Great to see the improvement as this ensure that we are going to have a good and stable official release when the time comes http://samsunggalaxysforums.images/smilies/smile.png

Ah sorry for the doubled post, donno how could I miss it :(

Although the GPS is pretty good at the moment and there is nothing I am awaiting for improvement or fixed in the current firmware but I think I will give it a go as well this weekend ;)

Hi All,

Its been a long time since ive last posted hence I am still on FWJM5 with the one click lag fix.

I want to try this firmware when I get in today but just want to confirm if there's a difference in installing this firmware compared to when I installed JM5?

What I would normally do is put the SGS in update mode (3 button option) connect to Odin, then just flash all the files ive downloaded and it works.

Is this the same procedure for this 2.2 update? and is there any side effects e.g. 3 button combo getting lost, product code, locks?

Thanks

p.s. I am on a unbranded SGS.

Yes it is same way as you flash JM5 just make sure dont restore the system data and app's data from your backup after you flash to 2.2.

Also it is adviced to clear cache partition, reset factory settings and format internal SD card if you experience any FC after flashed to 2.2.

Thanks for your replay, however how do I format internal sd or clear cashe? Is it from the wipe data option wen doin the 3 button combo?

Yup, in the recovery mode ( Volume Up + Home + Power), you will be able to do all that.

FYI, when doing odin flash, you need to go to download mode (Volume Down + Home + Power)

I have now begin the process........
512 pit
re-partion enabled

.......as guided from xda and tiptonic for the rest

So far it has installed if no errors and everything has seemed sync well, however google map is not working?

it gives up with network error, however i can browse the internet?

Ive cleared the maps cashe still the same problem?

Upgraded my phone to the new JPK 2.2 firmware yesterday. Was good timing, since that release came out the day I was going to flash to the slightly older JPH, which had a few bad bugs. The JPK release feels extremely close to a release version everyone, its running very smooth, and I haven't had any problems yet. Enjoying Chrome to Phone (well, actually Fox To Phone), and Flash immensely, protected apps show in the Market (think Angry Birds), the new Gmail application is interesting too, the Music Player is finally perfect (no more crashes when trying to arrange by Artist), and the icing on the cake is the BT keyboard and mouse support (rather fortuitously my BT mouse also arrived in the post yesterday). I haven't yet tried the GPS, but people are reporting much improved performance (I've never had problems on any firmware, go figure). Samsung have kept their flawed RFS file system in place here, but despite 14 hours uptime now the lags haven't yet started, so whatever they've done for lagfixing is at least somewhat effective. Unfortunately Voodoo lagfix isn't available for 2.2 yet, but if I do have problems the One Click Lagfix is available.

I flashed JPK yesterday using 803 PIT file and repartition, phone seems great, no need of lagfix in my opinion, i tried it with JPH and didnt notice any change to speed, iv only rooted this firmware, very close to actual release now.

I think this is final release, for the first time when I open phone info I see under build number FROYO.XXJPK like I have had on Éclair, factory delivered. There is also time of build when you type *#44336# like on all official releases...
Anyway, final or not, it runs with no problems so far for me, and I know that Samsung can give official releases like this (remember Samsung i8910).
Rooted and lagfixed just to add

Just did mine. All seemed to go OK until I tried to get into recovery mode - the phone just powers up as normal. Download mode works OK. Tried reading through the XDA forum on this and someone else had the same problem but I couldn't see a solution to it anywhere. Anyone else had this problem?

When you press and hold the 3 buttons to the recovery mode, did you see some small texts right after the "Samsung GT I9000" screen? As soon as the small texts screen comes up, you need to release the "Home" button because the first item in the menu of the recovery mode is reboot phone, and by holding the home key will command the phone to reboot as normal.

Just flashed mine a from JPH to JPK, cannot see any significant improvement maybe thats because JPH is already very good to me.

Restore system settings, apps + data straight from titanium backup and all goes well.
Can see protected and paid app in market (same as JPH).
Twlauncher Edit menu from homescreen is back (wasn't there in ZSJP2).
Quadrant score 1020 without any lagfix.
GPS seems to get locked very quick, will try the accuracy later if I have any chance.

Got there eventually - just seems to be a lot more fussy than before. Now the joy of trying to get everything back on the phone again :)

I've had it running a little over 24 hours and I have to say I prefer JPH. I did the same thing as JPH - full factory reset and format internal SD, then load all my apps back on etc. I actually get lag more often in places I didn't before. A couple of things that are a little better:

1) It used to be very very slow at bringing up the keyboard in many apps. Now it's just very slow rather than very very slow :-). I really hope they can fix this as that is my main gripe with these froyo firmwares.

2) It used to force close on some apps randomly and you could just restart the app and it would be fine. I haven't had a force close on this firmware yet.

Having a problem flashing this, used the 803pit and files frm samfirmware using re-partition and getting errors, only gets as far as Samsung logo then black screen.... :/

I use 512.pit but I don't think that is the problem. I did use 803 the first time and it was ok just the *#1234# not showing the CSC properly so I reflashed it with 512.

For the black screen problem: After flashed, see if you can access to recovery mode and do factory reset, cache partition wipe and internal sd card format.

Thanks, works after doing all three.

Anyone else notice the colour is different with this firmware? it's like a weird tint to the display now.

Not sure I like this.

I wondered about that Shocky... yes it does seem that the colours are slightly different.

Is it the brightness settings? I can't see the different. Maybe that because I have mine set to the lowest in most of the time.

Following Brigg's guide on flashing, but must be missing something - as I can't seem to see where to download JPK from over at samfirmware ?
Plus, can I flash straight from JF3 to JPK ?

Any advice - much appreciated !

Hi all

Its been 2 days with JPK however its seems to lag allot, even loading the phone,messages or contacts lags, browser lags as soon u open a couple of tabs.... Flash slows down tje webpage however plays fine.

Does anyone have this problem? Im on a clean install and all my apps are fresh from the market...

Seems fine to me no lagging what so ever, however i have had a problem with the last 2 firmwares that after a little while my music disapears in the media player and the only way to get it back is for the media scanner to run to pick it up. Either connect it via USB and disconnect or restart the phone. Have to do this twice a day. Considering i play music twice aday it is very annoying. Some times i could be playing music and will then loop, check the play list and the only thing left is the track i am currently on in till i reboot the phone. It's becoming very annoying.

I dont have any lags what so ever, infact i noticed its a little faster then JPH, for you guys tha are having problems, i dont believe in the automatic backup and restore of apps, i suggest to stay on the safe side and reinstall everything manual again, this is what i do before i install any new firmware:

1) take note of all my installed apps and write it down in a word program.
2) transfer my photos/ videos/music to pc
3) Turn of phone, access recovery mode and wipe 'cache partition' and 'data factory reset'
4) install new firmware
5) to make sure all goes well no problems, again access recovery mode and wipe 'cache partition' and 'data factory reset'
6) Manually install all apps from the market again :)

This might be tedious work, but i hadnt had a problem yet since i purchased my phone, i couldnt reproduce the colour tint, and its as fast as it should be.

Dazz,

I never had that problem, did you try doing the "stop scanning" of media file at startup! that might have caused your issues!

im very happy with this update far better than jph i think, Hasn't crashed yet and runn very smoothly. and everything seems to work for me. i dont seem to have a weird colour tint to.

Gps is slightly better than JPH, but still unusable for me...

takes ages to lock and when it does it darts around the place ever when just walking.

thanks for your reply,

However Mine was a clean install of the FW and clean installed from the market, hence no backup apps were installed. I also wiped cache and internal SD after the update to JPK and still with these lagging problems....

1. I have launcher pro installed may this be the problem? Has anyone experienced this? As home switcher does not work with 2.2 therefore stuck.

2. Scrolling seems fine and fast so no lagging there.
3. installing apps seems fast and handles better than 2.1 did.

Its just the phone function it takes a second or more each time i load even when not closed. on 2.1 if already open and just loaded from memory again it will be up instantly.

Does anyone recommend to do a re-installed or is this normal?



Solved my problems, now the phone runs perfectly....

I wiped and formated SD, then installed the FW and thats it..didnt bother with the wipe again as that what i did before and had problems...

However I have not installed launcher pro yet, so will see if that what caused the problem....

Just before I give up waiting for the Official release and just go ahead and flash my phone, is it better to restore to shipping defaults before Flashing or just go with the flashing straight away.
Phone's rooted with no other customisations.

Always best to wipe the slate clean before a flash.

I'm actually going to flash back to JPH. Adobe flash enabled websites worked perfectly before, now it's a mess. It lags more than JPH for me too. JPH had its own problems but they didn't bother me too much.

Dazz,

Nope have to let it run just out of the blue it no longer picks up the media, i wouldn't mind so much if i could get the media scanning to run when needed rather then rebooting the phone every time.

Installed this firmware & rooted the phone yesterday & so far everything is running fine. Followed the instructions here :-

http://forum.xda-developers.com/showthread.php?t=790686

My previous firmware was JM8 which ran really smoothly, swiping between screens was silky smooth, on JPK there is just very slight lag between screens, just a fraction of a second so no big deal. No problems with colour tint.

When using the file manager I find two "Lost.Dir" on the phone, one on internal card & one on external. Even if these empty directories are deleted they come back again after a reboot ?.

Just wondering why this happens.

Also, on previous firmwares MyBackup Pro would make the backup on the external card. But on this firmware it backs up to the 'sd' folder on the internal card.

OK, I might try and flash it again with those instructions. The only thing I did wrong was use the wrong PIT file. I'm not sure if that will fix it but worth a shot since most of you find this firmware good but I find it worse than JPH. This is the first time the later firmware has been worse than the previous one for me too.

Went for it as well, so far so good, thx everyone for usefull info :)

I'm liking it at the moment, apart from the 5.1 surround in the video player. I keep getting popping sounds

Well, you probably have to reinstall your firmware, did you have that problem as soon as you installed JPK or after the applications?

Bluetooth HID profile support is working brilliantly for me with this firmware. Last night the missus was on my laptop doing some priority work stuff, plugged my GS into the 42inch tele and then used BT keyboard and mouse, absolutely perfect.

Heres a video to show it off:


http://www.youtube.com/watch?v=21aVbYpgrRA

Great video NZtechfreak! Now I am tempted to get a BT keyboard and mouse :D

Yeah great video man, HID seems to work awesome on this phone, btw your phone seems fast, and i like your menu as well, what customisations have you done..

Have just flashed to JPK.
All seems to be well but I have a problem with getting the bbc Iplayer to work.

It works great with WIFI but when I try to use it over 3g, Iplayer comes up with a message stating that it is only available on three and vodafone contract.

I am on Vodafone, have checked all the apn settings and they are as they should be.

Anyone got any ideas what the BBC iplayer site is looking for from my device which it is currently not seeing when I'm trying to access it over 3g??

Great video NZtechfreak! Now I am tempted to get a BT keyboard and mouse :D

You can pick them up pretty cheap, so its probably worth it! I got the mouse when I had confirmation about HID devices working, was like $6 or something from Ebay... For keyboards I'd think about spending a little more and going for the Freedom one that supports HID and SPP profiles, because that should work with more devices (you know, assuming you get tired of your GS in the future).


Yeah great video man, HID seems to work awesome on this phone, btw your phone seems fast, and i like your menu as well, what customisations have you done..

Yeah, its running nicely at the moment - thing is that its just the Froyo firmware without any lagfixes on it. I've been on it about 10 days now, got my 50 or so applications installed, but so far not felt any need to install a lagfix... In terms of menu customisations I haven't really done anything. Its LauncherPro in landscape in the applications tray, TouchWiz Froyo update in the notifications tray with the auto-rotate and GPS switches in there, and the different icons etc in the Settings menu is just standard in 2.2 firmwares...

Sweet thanks matey, the app i was talking about is launcher pro, never used it before so it looked cool, i only have like 5 apps installed on my phone atm, being too busy with exams, thanks again :)

LauncherPro is brilliant, make sure to donate for the Plus version too - it has a series of excellent widgets not available on the free version (including excellent FB/Twitter widgets, and the combined Friends widget, and also a truly great calender widget, something that was missing on the phone natively and really bugged me, theres a few other widgets too, but they aren't as good as those ones).

first post so be nice

Just flashed i900jpk working so far, bbc iplayer works but voice and video dont match up bit weird.

Does not seem to be rooted so had to root it, then used one click lag fix.

Quadrant score is 1850, which is not as good as the stock 3 mobile firmware which was over 2000 but loving it so far.

Don't worry about the Quadrant score, the OCLF is a benchmark cheat, the numbers don't really do anything but confirm its been applied (the false numbers are why Voodoo has better actual performance, despite lower benchmarks, will be good when we can get Voodoo on 2.2 firmwares).

Can you guys setup LauncherPro as default in JPK? It doesn't work on my phone, I can start it, but when setup as default in Home Switcher it does not remember this setting and goes back to TWLauncher.

Rather than using Home Switcher hit the home key after installing LauncherPro, it'll pop up with a box that asks which launcher to use and there is a box to tick to assign your selection to default. Should be fine after that (I believe Home Switcher does not work with 2.2).

the thing is I cannot start it any other way then using Home Switcher. Open button is not active :/

OK - I'm trying to reinstall now - didn't help.

So I just went to Applications, cleared defaults from TWlauncher and after pressing Home I got the default application popup NZtechfreak mentioned and works fine now - thanks all for help :)

I can set LP as default in my JPK build without any problem, have you tried reinstall LP?

Another reason to go for JPK is that Skype works on it 9see my thread in the applications subforum for more info).

After I flash with Odin 1.3 using 803.pit either with re-partition or without I get an error message which says

E:Can't mount /dev/block/stl10
(Invalid argument)
E:copy_dbdata_media:Can't mount DBDATA
your storage not prepared yet. please use UI menu for format and reboot actions
copy default media content failed

what can I do?

Why would you flash with the 803 pit, when the instructions specifically suggest not using it?

Try and reflash with 512 pit?

do you guys actually make calls, or do you just tinker ??? :lol:

I don't make calls at all. I just use the phone to fill time lol. My friends think I'm mad because every weekend I wipe the phone and flash another firmware. Who buys a phone to actually make phone calls? ha ha

Very true. haha.

Though - I believe SamFirmwares recommend 803 pit. =s It's worked so far for me. I dunno.

Just press format on the menu and it should work I believe. I had that problem too.

Telephony has been the minority of my mobile phone use for about 3 years now (ever since the N95 came out).

The second time that I formatted the internal sd, cleared the cache and factory reset it worked
