ok very confused, i gather xx means english (or european?), and i9000 is the SGS, but...

can anyone explain the naming scheme for the last bit of the firmware? :confused:

i have a uk vodafone galaxy s, with the following:

pda: I9000XXJF3
phone: I9000XXJF3
csc: I9000oXAJF3

are they recent versions? how far from the most reason are they? what would the most current versions be? (and also what is the difference between pda/phone/csc?)

many thanks if you can straighten this out for me...

Firmware is from June 2010. There are other threads to your questions but

Latest firmware for 2.2 is I9000XXJPK and for 2.1 is I9000XWJM9 from http://www.samfirmware.com (http://www.samfirmware.com)

And welcome

The naming convention confuses me too charlie.

What i often wonder as a T-Mobile user who has no flashing / rooting exp is what is the difference between the various firmwares. I read about JF3's and JE6's but they really mean nothing to me.

Thanks for the reply Doomed - do you know why there are named like that, and why not, say, 2.1, 2.2...?
(and GC its nice to know i am not alone!)

You say latest firmware for 2.1 and for 2.2: is the 2.2 included in the firmware, or do i need to install the correct one for what i am using; if i install the one for 2.2 the phone will upgrade to 2.2? Sorry if that doest make sense, but i cannot work out if firmware includes the OS.

...i cannot work out if firmware includes the OS.

I am guessing, at 220mb, that I9000XXJPK does include the OS

Yes, the firmware includes the OS.

If you install an XXJPK firmware, you will be running FroYo (2.2).
I've seen the way they do the naming posted on either this forum or xda-devs... It's something along the lines of the J for the phone, the P for the month, and the K for the week.. Close to that but it's not absolutely right.

Example of firmware naming breakdown for Samsung Galaxy S I9000 running firmware I9000XXJM1

I9000 = Phone model
XX = Region code (XX = Austria, Belgium, France, Germany, Hungary, Italy, Spain, United Kingdom)
J = Year of release
M = Month code
1 - Revision version

so I9000XXJM2 would be a newer revision of the JM1 firmware.

BUT

It doesn't always work out exactly like this because that would be too easy :p

The easiest way to refer to the major updates to the operating system is by their "food based" nicknames...

The current one for the Galaxy S is Eclair (otherwise known as Android release 2.1)
Pretty soon we'll have FroYo (otherwise known as 2.2 - FroYo is short for Frozen Yoghurt)
If we're lucky and the SGS is still supported by then, after FroYo will come Gingerbread...

And yep, I'm afraid JF3 is quite an old version :o

....The current one for the Galaxy S is Eclair (otherwise known as Android release 2.1)

When you say current, some people have 2.2 (through official releases), no? :confused:

The reason I ask is I cannot get Kies working, so I was considering using Odin, and I9000XXJPK, as per Doomed's comment. Is that 1/2 sensible?

Can't get 2.2 officially yet, but the newest now is JP6 (still 2.2) from another thread on here which has installing instructions too :)

As Doomed said, at the time of writing 2.2 isn't officially available, so yes, people do have it installed, but not the official version.

If you can't get Kies working then using Odin to flash a new firmware is the only realistic alternative. You might as well wait for the official 2.2 release though because it should be here any day now. Then download that and flash it using Odin.

I presume you have checked that you can get to recovery mode using the 3 button combination ??

Thanks for the help Goots/Doomed. With every answer I feel more lost!


...wait for the official 2.2 release though because it should be here any day now. Then download that and flash it using Odin

So when the official release is out, will it not go over the air? If I cannot use Kies will I have to flash it using Odin?

No I havent, although I checked out tiptronic's guide to recovery mode (http://samsunggalaxysforums.com/showthread.php/1237-3-Ways-of-getting-to-Recovery-Mode) and it points out the need to reset the phone before flashing to avoid some common issues. If I do go down the Odin root, will I have to factory reset my phone as well?

Samsung have already stated on their twitter feed that the FroYo update in the UK will be distributed through Kies, so if you're having no luck with it then your only other realistic option is to use Odin to flash the new firmware. There is plenty of information on how to do it on this forum, and Tiptronic is particularly helpful when it comes to using Odin.

After flashing any new firmware it is advisable to do a factory reset, especially so after a version jump as big as 2.1 > 2.2, though it's a not as big a deal as it sounds.

You really do need to check that you are able to get to recovery mode using the 3 button method though, because if you can't, I really wouldn't advise changing your firmware by any method. :(

Luckily, there is a solution available that will enable 3 button recovery mode on your phone even if it has been disabled.

Hi Goots

Yeah I have been doing my homework: I can get into download mode (if that is what it is called - with the robot and shovel icon) using 3 buttons, so I think (but will check 1st!) it will do the same for restore mode (I got the impression if one is blocked both will are), either way - I saw the way to enable, doest seem too difficult. Rooting seems pretty straight forward as well.

Just 3 things I am not so sure about:

1) Does the phone have to be unlocked in order to be flashed via Odin
2) I read somewhere about backing up an encrypted (efs?) folder (in case the EMEI no. changes?) is this necessary/ advisable?
3) You said it isnt too big a deal doing a factory reset - what about programs (the only one I have purchased is Tasker, but I would miss it!)

Hey Charlie,

Regarding the 3 button combo, phones which have recovery mode disabled still work in download mode, so just because you can get that doesn't mean that recovery mode will work. You really do need to check, it could be a lifesaver.

1) Not sure what you mean by unlocked there, if you mean not locked to a network then no, that won't matter.
2) I would totally recommend backing up your EFS folder. Yes there have been reports of IMEI's getting changed during firmware flashes, and if you haven't backed yours up before flashing then you will be screwed. The best way to see/backup your efs folder is to root the phone and buy root explorer (about £2.50 but absolutely worth it). You should then copy the whole EFS folder to some secure location. I have one copy on my SD Card and another on my PC.
3) If you have already purchased Tasker then it will be available for you to download again as many times as you like. I had bought 2 programs (Root Explorer and ROM Manager) and after I flashed new firmware I only had to log back into my account and they were downloadable without paying.

I would recommend you create an appbrain account and then install the appbrain app on your phone. This is a good way of keeping track of free and bought apps, and can be used as a great way to find if there are updates available for your apps just by clicking the "sync with appbrain" button.

so another question. first of all Ive looked into rooting and nowhere did I see mentioned the need to backup the EFS folder but i guess i should do my homework a bit better before i do it. second I probably won't be able to see the contents of the folder much like charlie here and I live in greece which means no matter how much i want it I cant buy this app you speak of Goots so since I have to back up that folder how can I do it? and lastly what exactly does the factory reset in recovery mode entail? say i root my phone and flash new firmware until (if ever) froyo is released. can i just factory reset it when froyo comes out to spare myself the hassle of unrooting and all? just factory reset it and then upgrade to froyo. I can backup my apps and sms and contacts so ill be fine if that is to be an issue...

The efs thing is only if you intend to flash new firmware and you definitely won't need it before rooting.

The other thing about living in Greece is that it might not matter if your IMEI is changed/lost because I don't think networks ban phones by IMEI over there, but I'm not 100% sure. It would be best to find that out from someone who knows more than me. Banning by IMEI is the way it's done in the UK and lots of other places, hence the need to back up that folder - it contains information relating to your IMEI and other phone-specific details so the efs from my phone wouldn't rescue Charlies phone if his got screwed up during the flash.

The idea of a factory reset in recovery mode is to put your phone back to the exact state it was when you received it. This will include the removal of any apps and any network provider added crapware etc.. The factory reset done through the software (Menu > Settings > Privacy > Factory Data Reset) is more to erase passwords, contacts, memo's etc basically all the personal stuff you might have stored on your phone. Be aware that if you flash a new firmware now, then 2 months down the line do a factory reset in recovery mode, it will only take you back to the barebones of the new firmware you just installed, not the one you had on it when you bought it.

As for you not being able to get the Root Explorer app, are you saying that you can't access the marketplace from Greece ?

oh well you answered my question about the reset. I wanted to flash new firmware but if it's gonna take me back to the new firmware then no need in that. I was just thinking that it would be good to have a backup in case the new firmware proved to be problematic in any way and would restore me back to original authentic settings so my firmware update (when that comes) would be legit. kinda like jailbreaking the iphone and then restoring it so you can update the OS but as Ive seen thats not the case as to connect it to a program to restore the original firmware but had a hope when i saw the system restore option. anywhoo as for your marketplace question I can access marketplace just fine from here its the paid apps I can't access since they haven't been released to the land of economical failure just yet.
but btw in your personal opinion should I/we flash the new firmware? I just cant take this lag anymore

Ok,

I have checked, and I can get into recovery mode.

I have rooted the phone, and used ROM Manager to make a back up image, plus I copied over the /efs folder, having rooted the phone, using Android Terminal Emulator.

So I am now ready to update either by using ROM Manager or Odin. Having a bit of difficulty finding a suitable ROM... :confused:

I am using this guide and the linked files (xda-developers.com 807886 (http://forum.xda-developers.com/showthread.php?t=807886)) to update to JPM, although if anyone knows where I can get a ROM I can use with ROM Manager I would be very grateful for a link... :)

OK mate, while you've been away sorting all that, a semi-official FroYo release has occured :)

If you FOLLOW THESE INSTRUCTIONS (http://samsunggalaxysforums.com/showthread.php/2330-Good-News-Froyo-is-here?p=14626&viewfull=1#post14626) exactly, it will work perfectly. I'm using it now.

It's scary doing it, but that's half the fun I guess.

One thing, very important - MAKE SURE YOU REMOVE ANY LAGFIXES FIRST - leaving it Rooted is fine.

This solution needs you to connect via Kies obviously...

Was uber excited for a second, then read the Kies bit. I am running Win 7 (64) (not sure if it is because of that or what) but Kies dont work for me :mad:

So still stick with Odin/ ROM Manager... :(

Any thoughts?

Done! Thanks for the help. BTW JPM is so much better - much more responsive :D

Draps, I'm still running JPK :mad: Or is it that I'm just lazy and haven't bothered to up date :confused::)
