Need help downgrading to gingerbread 2.3 - Galaxy S II Q&A, Help & Troubleshooting

I need to get my device to 2.3, but I can't find the download I need and i cant find my csc code *#1234# or what ever it is doesn't work for me. My device is rooted. Please I really need to get to 2.3 quick, If anyone can help me it would be great thanks. I'm a noob to this but I have rooted my phone and know what to do with odin. I just need to know where to download my firmware.

Go to Samfirmware, use the pulldown boxes to find a GB stock rom for your carrier/country (the other sites link back to Samfirmware's files in almost all cases), download it, flash it with Odin. Tho you may have trouble getting 2.3 - that's ancient.
Also, if you're returning the phone for a warranty claim, you do not need to go back to 2.3, irrespective of what you may think or what you may have been told. You simply need to make sure you have any rom for your carrier/country on your phone (you could flash the latest JB rom released by your carrier, for example), your flash counter is reset, do a factory reset once you've flashed the rom just in case, and send it off.

[Q] DO I need to change my CSC

Hi
Ok so I was with o2 on KF3, I've now flashed stock samsung firmware from here http://forum.xda-developers.com/showthread.php?t=1075278
I'm using the most up to date XEU one which is
XWKI4
Firmware info
PDA:XWKI4
PHONE: XXKI1
Date: 14/09/2011
Android 2.3.4
All o2 stuff has disapeared. I've read through the forums on changing the CSC and am confused.
Do I need to change it to XEU now to be able to update through kies? currently it comes up as 02U.
The firmware flash didn't reset my phone everything was as before. Which was nice, however I want the option to get the updates through kies or by flash.
Am i right in thinking I would have to change my CSC for this?
I see views but no replies - anyone no the answer or is it a smarties job?
Tried to change it anyway but phone wont let me dont even get a keyboard. Stuck it on clipboard selected all on 02U then pasted XEU ontop all i got was an error to say it had to be 3 characters any clues?

So after some more internet scouring and no help here it appears i need to flash a multi csc fw then change csc then reflash the one i have now......... Can anybody verify if this is correct or not?

To use kies again you will have to flash back to the original firmware,in your case carrier firmware,that came with you phone.If your firmware is not official or doesnt match your product code then kies will say that "this firmware cannot be updated" although your phone will still connect.The CSC firmware you have is a mono-csc package.If you try to change it or install a custom ROM on top it will say "CSC-UNKNOWN" because for custom ROMs and other changes to be done there needs to be at leats 3 CSCs in the firmware.The best thing you can do if you want to stay on this firmware is stay with XEU for your region or if you want flash the OXA multi CSC pack.It has varios CSCs to choose but i cant remember if it has XEU.You could always flash a custom ROM that has a multi CSC package built in to it like Omega ROM which im using but this of course means you cant use Kies.So the choice is yours.Stay with XEU if you want to keep to stock or OXA-multi CSC if you want to flash a custom ROM or back to your original carrier firmware to keep using Kies.
EDIT: Theres nothing Kies can do for you that XDA cant.Im in Spain on XXKI4 (Poland 2.3.5.) running Omega XT v3.0 ROM which has a EUR CSC for Europe built in to the ROM itself.So Ive got a Europe CSC thats works fantastic with a version of android that isnt even released in my country and a ROM thats fast and stable that gives me 2 days battery life with 3G on all day with moderate use.
thanks
Hi
Thanks for that, I guess I just wanted the best of both worlds, to be able to flash official roms from XDA as they come out for XEU but also have the ability to do the same through kies - ODIN was painless enough so as u say there's nothing kies can do for me that xda can't in that respect
Eureaka
So I factory re-set my phone from the recovery menu.......bang csc now reads xeu so it would seem to be that flashing the firmware as above won't sort csc on it's own unless a multi csc, but it doesn't matter which route u pick multi/single csc fw package you have to factory re-set to change it.
At least I know if I ever need to send the phone back to 02 I reflash, factory re-set and everything is as should be, although will the binary counter hint i've been flashing?

For the counter just buy a jig on ebay or maybe from a store if you can find one that sells them.Ebay always has them.It wipes the counter clean so Samsung dont know that yourve been playing around cos if the counter isnt at 0 then your warranty is void.Cost 2 bucks.The latest 2.3.5 official firmwares,also available here on XDA,have a new bootloader which is un-wipeable but there is an odin flashable old bootloader which allows you to flash the latest version and still wipe the counter.you can read about it here at the bottom of the Frankenstein section bellow XXKI3
http://forum.xda-developers.com/showthread.php?t=1075278
I also wanted the best of both worlds but at the end of the day all official kies firmwares you can find here from the link i just gave you anyway and flashing custom ROMs and back to stock and custom and stock again could also put your IMEI in danger of being corrupt.
EDIT: Heres a good IMEI backup method http://forum.xda-developers.com/showthread.php?t=1308546
Wasn't aware of that risk! Will have to get a jig as if phone busts it will have to go back via my insurance company and I'm sure they will check!
Also I've got Odin 4.42 now not odin 3 1.85 does anyone know how to use it to flash the GS2 as it's options are slightly different e.g one tarball support - dedicated option rather than just pointing the pda field at the single tar.
also the reset time has a value of 300 rather than just being a tick box. Other than that it's pretty much the same

About the new Odin im not sure.If your not sure then its probably a fail-safe bet to stick to v1.85,at least you know it works and messing around with things that your not sure about could end up with a bricked phone.Ive been flashing for donkeys and im happy with v1.85.If it aint broken....so ill stick with it.A jigs good to have just incase.If something happens you need to wipe the counter before sending it back.An IMEI backup is a MUST HAVE.Not really if your only flashing original firmwares but if you want to flash custom ROMs then YES its possible that something could go wrong.Happens not to often,to some people never,but if you dont have a backup then there is no way you can get your original IMEI back without sending it back to the service centre and that will cost you.No IMEI means on conection at all.No 3G,HSPDA or even signal.Not good at all
Cheers for the advice will stick to 1.85 it works lol yeah i stick to official fw interested to know how imei can get fried though

[Q] Car Phone Warehouse

Hi there can't post in Development so here will have to do...
Ex SE Satio user moved over to android SGS2 and got one late last year from CPW (Car Phone Warehouse), Unlocked and with cpw stock firmware, I think it was XEU or one of the general ones, I rooted it using odin and was happy as larry, until the proximity chip failed, so I rehashed it back to Out Of Box and sent it back.
Great Then then sent it back with a different firmware, I'm still getting my head together with this but I'm sure I cant find it? and there is hardly anything online about it.

I also failed to state that its...
2.3.3 and Kies say's "THERE WILL BE NO MORE UPDATES FOR THS PHONE."

Well if you want to root flash a cf root kernel via odin from the original development thread.
Also check out infratechs thread to see if he has this firmware there incase you need to revert back, once rooted just make a backup via CWM either via recovery mode or using the CWM app that comes with cf root.

Hi mate and Thank You for your quick reply. I've scoured the threads and the closest I've found is..
XWKDD
Firmware info
PDA:XWKDD
PHONE: XXKDH
Build date: 26/04/2011
Generic XEU
But I thought that when you rooted your device it had to be identical, I could flash Ice Cream, but then I wouldn't have anything to back up to if my device blobs?
O2 say's I shouldn't have this firmware and so does Samsung, Kies actually said..
"Your device does not support software upgrading via kies"
I's that odd?
Don't worry about it, if you've got an o2 model just flash the latest UK firmware for o2, again in infratechs thread or maybe sammobile. You can flash o2s CSC anyway that will give you back the splash screen and such.
For now if you want to root, cf root is the easiest then flash away using CWM any of the plethora of roms available.
I suggest you flash a stock rom from Infratechs thread so you can update to the latest if you want LA2, then use CF Root to root. Then if you want ICS just flash that via CWM.
You can also use Checkfus (search on here) to find/download the latest firmware for your phone/carrier.

Its not O2 firmware its CPW firmware CPW is the clue
KD was a very very old firmware May 2011
What has the firmware to do with O2 its not an O2 phone .
UPGRADE CHOICES
One ask CPW service for an upgrade
Two wait for KIES upgrade if CPW upgrade KIES .
Their should be a CPW firmware and most definitely an O2 Firmware in the branded providers rom section .Or via CheckFus that should give you a backup of whats on the phone .
Carrier branded .

As you said JJe, it is a CPW rom, and I knew it was an old one, but it's odd that CPW are sending refurb phones out with such an old ROM on it. I've decided to bite the bullet and go with the original ROM that I got with my first phone...
Product Code: GT-I9100LKACPW
Version: Android 2.3.3
HIDSWVER: I9100XWKE7/I9100CPWKD1/I9100XXKE4/I9100XWKE7
Bypassing this and going for...
I9100XWKI4/I9100CPWKH1/I9100XXKI1/I9100XWKI4 (2.3.4)
This is the original firmware plus KIES update to 2.3.4! I know that CPW were sending NEW phones out with this, so this will have to be my BackUp If my hardware blobs.
I'ts a shame I couldn't find the original ROM/Kernel. Checkfus did come in handy after all.
Many thanks for your help and patience you 3.
Now I just got to cope with FBI shutting down MEGAupload, as most of the Rom's etc reside there.
hey ya, lets say someone i know (wink ;D) is employee at carphone warehouse, and to tell you a fact, the repair centres tend to care very little if youve changed the firmware, at most they will charge you £10 to 'upgrade' the software to the latest official release, if you cant find it, i really wouldnt worry to much, most staff dont even realise what the yellow non stock firmware triangle is, though i would be sure to get rid of it just incase you get one clever clogs but for the most part, no big worry really
Just my luck flashed new ROM and i'm gettin "The process.com.android.phone has stopped unexpectedly. Please try again" every 5 minutes when i'm navigating through menus and that.

Make sure you have wiped data/cache and dalvik cache via recovery (If you have CWM recovery) otherwise pick a rom from the stock rom thread that says wipe, flash it via odin, then flash the new rom you want.

Turns out that it's incompatible with my sim card, the phone works fine when I remove it, but as soon as I put my sim back in I get the same error?
CF-rooted fine,CWM etc ok, but still this error, might have to try another ROM
Sussed It!
Flashed to XXI1, then flashed the CF-Root Kernel and wiped it, looked like veyka, it was my Backup that I was Restoring, because now it works fine with the SIM card, something from the Backup from that ROM was incompatible with XXI1!
Got just a DATA backup on CWM from main backup, will see what I can restore safely!
Got Yellow Triangle, no Jig. will try SuperOneClick method
Trial and error eh?
Thank you again. (buttons pressed.)

[Q] Multiupload is down and I need to download links to get ICS

Hi Everyone.
I'm an Android amateur. Basically I want to install the official ICS software on my galaxy s2 Orange UK phone now that it is out, however, because I have flashed it previously, Kies says "Your device does not support software upgrading via Kies"
I want to use the links on this thread: http://forum.xda-developers.com/showthread.php?t=1113928

Gone gone .
Search as said via Google try sammobile.com try Checkfus are all the usual answers to your question .
Flash the Orange firmware via Odin or download it via Checkfus .
jje
just asking but as youve already flashed anyway why not just flash the sim free software from http://forum.xda-developers.com/showthread.php?t=1544487 instead of the orange branding one? Wont have all the horrible orange branding on it then
First of all you are going back to GB from ICS so you will need to flash the old bootloader before you flash the firmware to avoid bootloops.Follow these steps.
1.Unzip file from below to get the old bootloader tar. file first.
2.Open Odin and put the tar. file in PDA and connect phone.Without selecting anything else hit START and it will take about 4-5 seconds.
3.When done disconnect phone and let it boot and then turn it off and boot to download ready to flash firmware.
4.Flash this -2.3.6 GB Orange U.K (cant find the other one)
http://www.hotfile.com/dl/152491674/56b608a/I9100BVKL1_I9100ORALB1_ORA.zip.html
This version has no root kernel but if you want to flash via kies you wont need it anyway.Now update via Kies.
ALTERNATIVE WAY..................................................................................
Latest official kies release for Orange U.K
http://www.hotfile.com/dl/153501669/3ba8630/I9100BVLPB_I9100ORALPB_ORA.zip.html
CF-Root kernel if you want to root
http://download.chainfire.eu/143/CF-Root/SGS2/CF-Root-SGS2_XX_OXX_LPB-v5.2-CWM5.zip
This is and older kernel and could give problems mounting storage.At the moment there is no specific CF kernel for you unless you want to try a different one or SuperOneClick (not a good idea)
OTHER OPTION,
U.K. and Ireland unlocked Kies official latest release.Kies will still work but if you dont have a factory unlocked phone then the updates wont work anymore untill you reflash your carrier ICS firmware.
http://www.hotfile.com/dl/153177481/9861a3a/I9100XWLP7_I9100XEULP5_XEU.zip.html
CF-Root kernel (stable)

@ cooza
you do not need to flash boot loaders when you flash using Odin.
You don't need to flash boot loaders even when you flash using cwm.
You get boot loops when you go from ics to GB with out wiping.

True that its not really needed for Odin but thought Id post it anyway.Ive suggested this to people with bootloops who have tried everything and still have one and it has been the only thing thats worked when going from GB to ICS via CWM and in a couple of occassions via Odin also.More senior members than me also recommend it.It may just be luck or may not but Ive never seen it fail.If he does it nothing bad will happen to his phone anyway.
cooza you really dont need that,
bootloops fixed by right kernel's, wipe's, or best formating system partitions

[Q]Which stock firmware to use?

After buying my phone from a person (not an authorized seller) I factory reset the phone and it showed up in Arabic language, however since I accidentally bricked it I wasn't able to take a good look at what it's stock firmware was, Is there anyway at all to find what stock firmware I should be using? since I can't access the Lockscreen or the shutdown/screenshot features of the phone, I'm using a Turkey country 4.1.2 firmware
Go to Samfirmware. You can use the pulldown boxes to choose OS/phone model/country/carrier & it will give you a list of stock roms released by that carrier. At the end of the day it doesn't matter what (or even if) stock firmware you run, though obviously it might be difficult to get OTA updates if you're not running one for your country.
Well that's easy but they said on the newbie thread that in practice it's okay but it's not since the modems are different, and I already searched for a stock firmware but the problem is that the lockscreen isn't responding or not functioning (regardless of what screen lock you would like be it pattern or pin). They also said that I should use my IMEI to match the stock firmware I'm supposed to use? but I don't know that method yet.
If you flash a stock rom for your carrier, you will get a modem that's presumed they tested thorougly enough so it works for most people most of the time with their network before they released the rom.
If you've got that lockscreen issue, that's a different problem, but try flashing a stock rom for your carrier (and do a wipe after) before you do anything else.
An IMEI search won't give you the info you're after. And as I said in my PP, it's not important, but to make sure of things you flash a rom for your carrier.

Need I9100PXXLSS firmware for restore on dead i9100p

Hi all,
tried to root my phone with jeboo_kernel_i9100_v1-2a.tar using Odin3 not realizing my phone was an I9100p (they look the same ,almost). Anyway it booted up but i had no signal guessing this was due to it being the wrong kernel? I then tried to flash to CF-Root-SGS2_XW_XEN_LP7-v5.4-CWM5 this gave me only a bootloader screen. I rebooted jeboo_kernel_i9100_v1-2a.tar and i can now use my phone again but without the signal, i do however have super user and CWM on my phone. Im thinking its probably best to give up so ive found the original firmware i need : I9100PXXLSS . unfortuently all copies seem to be on hotfile which has recently been closed. Anyone got this firmware they could send to me? Thanks.
try to search for I9100XWLSW_I9100XXMS2_I9100XEULS5_HOME.tar and flash that.
also you can visit sammobile, they provide good and updated firmwares
And where do you think the OP went to look for this firmware first ?
OP - Samfirmware are still in the process of migrating their stuff to Terra, they started with the most recent firmwares & are working their way back. Try AndroidFirmwares.net & Samsung-Updates.com; if they don't have what you need, you'll either have to flash something else or wait until Samfirmware have what you're looking for back up again. You don't need to flash the exact firmware that was on the phone to get it working again. If your aim is to root the phone & flash a custom rom, any firmware for any country/carrier will do (but don't use 4.0.4). If the intention is to simply go back to stock & stay stock, use any other rom for your carrier (again, stay away from 4.0.4 just in case you decide to root it or whatever).
