[Q] gs2 back from ICS to Gingerbread HOW!!! - Galaxy S II Q&A, Help & Troubleshooting

Someone please help i have tried and tried to root my phone but to no avail. I want to go back to Gingerbread from ICS but what ever kernel i put on says its passed but i'm still on ICS.
As i've said my phone just wont root. And Kies says my phone does not accept updates. So is there a way to go back to GB? I dont care if i loose all my apps etc. I just wanna go back to GB. (Stock) if poss
If there is a way could someone help. All the links i find for GB seem to be dead.
Oh and I am not the greatest at jargon so an idiots guide would be needed as I am an idiot.
Thanks in advance

Ok, you do not have a nandroid backup of your former GB ROM.
Restoring this backup would be the easiest way to get back.
You are on ICS now, and un-rooted.
Maybe it is best to flash a new ICS ROM, such as XWLPD or XWLPF to your phone.
Have a look at Intratech's Official Firmware thread here => http://forum.xda-developers.com/showthread.php?t=1075278
There you will find the official ROM version as non-wipe installations and a description how to flash.
This is just to get a stable base to downgrade to GB.
Then choose the GB ROM version you want (also available in Intratech's thread), and flash it to your phone - in the same way you flashed the ICS ROM before.
After flashing, you may have to do a factory reset in recovery mode.
Press Volume UP + Home + Power button till recovery menu appears.
There you can choose to wipe data/factory reset.
Then reboot the phone.
Good luck!

Go to sammobile.com
Download a GB stock ROM
Download Odin for flashing
Flash the stock ROM
Your done
Chris.

Here's your problem. Flashing different kernel won't change your Android version. Flashing GB rom will. Go to sammobile, choose your phone, download whatever rom you want from the list (look at its version before downloading it) and flash it with Odin. Flashing rom includes kernel so don't worry, you can change it later.

Good instructions the only thing I`d change is swap steps 10 and 11.
10.. Start Odin as administrator on your PC.
11.. Connect phone to PC using original USB cable and wait for yellow confirmation box in Odin on PC before pressing start.
The reason being Odin can be a bit flakey if phone is connected first. It`s only a slim chance anything would happen but why take even a slim chance.

Guys my internet connection is a bit flakey nowadays with multiple disconnections so I can't download a odin gb package, I'm on ICS now but wanna go back to GB (having some network problems,just to check) I however do have a nandroid backup of the earlier gb. Now can I go back to GB by just flashing the backup over ICS? Or will that screw something up? (Diff bootloaders etc?)

Hi, I have the same problem as the OP but I'm unable to connect to ODIN. My computer(s) won't recognize the phone whatsoever.
I have a CDMA (US Sprint) SGSII with ICS KP8 (leaked, wrong region) on my phone and it won't connect to my PC. I've been searching for an answer all day.
I have: tried ODIN 1.85, 1.83, 1.3, uninstalled Kies, tried all my USB ports, tried all the USB ports on my other laptop, rebooted my laptop, and the phone many times. I've tried different cable as well.
I have the factory ROM zip file on my phone in a couple different locations, and I've been trying to get recovery mode to recognize it so I can "apply update from external storage" but it says E:failed to mount /sdcard (no such file or directory). I've done the factory reset and even *2767*3855# but everything brings me right back to a broken 4.0.3 with no wifi or mobile network. Does anyone have any ideas on how I can fix this? Thanks so much.

[Q] Restore to original rom with broken usb

Since a few weeks my Samsung Galaxy S2 gt-i9100 won't respond to any USB connection. No battery charging, no connection to pc, and also a JIG is not working.
Also note that when last charging a few weeks ago the phone was very hot and vibrating. After that the battery was empty.
When I connect the battery to another S2 it is charging correctly. When I put another battery into the S2 with the problem it is working, but USB is still not working.
I have flashed the phone in october 2011 to cyanogenmod 7.1, with the warning that I will lose waranty.
I think it is not a cyanogenmod issue, but a hardware faillure. Any suggestion how to get the phone back to original rom so I can send it back to samsung for waranty?
If it is not possible, any suggestions what to do know? Maybe getting the partnr GH59-10949A and replace it by myself?
Thanks in advance!

Triangle away only works on ICS roms.
1.Download any ICS rom, but get one that can be inscalled via recovery.
2. Download Triangle away, let it do its thing.
3. Download the stock rom you want, and sent it over wifi to your phone or download it on your phone.
4. Buy Chain fires mobile odin and flash it. Make sure you untick root, or you will need to go back to step 1 again.
Same thing happened to me they said I got water into the USB and wont fix it but I bought the parts to fix it on ebay.

I am currently on 2.3.5 and want to upgrade to ics. but i can't flash the phone as usb is not functioning.and anoyingly there is no OTA update!!! as i understand it I can update the firmware via Recovery by putting it onto the sd card and restarting in 3 button mode. Correct?
I think i have the files downloading from samfirmwares.com now, but with 40 min to download!

Clarification of stock firmware to return to

I want to return an S2 to stock...I'm in the UK, will XWLPD be the right firmware? I must admit I'm a bit confused as to the second link there : XWLPD Stock Kernel....do I need to flash both these things?
Essentially I want to sell the phone and have it as much back to original as possible. It is rooted and has CWM on it. It's currently running CyanogenMod 9.
I can't get any Phone / PDA / CSC info, because *#1234# doesn't work.
Use CheckFus to download whatever is the proper and latest ROM for your country and operator.
CheckFus is here: http://fus.nanzen.se/
Then using Odin flash the ROM to your phone, reboot, wipe everything and the phone will be as good as new.
If that answered you, click "Thanks".
Flash just the tar.md5, its the whole package

No. The full package is the first link, which has the stock kernel contained within already. The stock kernel in the second link is provided as a separate package just in case you need it, in the event you want to flash the stock kernel back after you've either flashed an insecure kernel to root, or flashed a custom kernel.
Dont forget to format the internal sd-card

I'm thinking of reverting back to stock as well, what are your reasons? I love the customisation of the AOKP ROMs but im really picky and some features dont work such as WiFi direct which is putting me off. Non AOKP ROMs dont have this issue but they dont support live lock screens so there is always something
Very minor but I am just that picky..lol Saying that I might go back to RR 9.6 as that seemed to work well for me. I am trying FOXHOUND atm and it seems good also.
B4 you go back to stock pls try Omega v13, there is stock, ICS or Black&Blue. I use v13 Ics as it's beautiful, truly. Everything just works. If you want AOKP, he even has an Omega v3.0 AOKP that I've heard is good too

Thanks for this. I've done this - how long should it take to reboot? Its gone to the SG2 boot screen and pretty much has stayed there for the last 10 minutes.
EDIT : No worries, went into recovery and erased cache/wipe data - now booting.
If your trying to get to original firmware, there are a few things we need to know.
1.. What carrier/provider are you with.
2.. What original firmware did you have, ie 2.3.3, 2.3.4
Download the original firmware from Samfirmware.com
Because you were on ICS; and you are selling the phone, you need to do more than just factory reset.
1 enter recovery
2 data/factory reset.
3 ( Advanced ), wipe dalvik cache
4 ( mounts & storage ), format system. format data. Format internal storage.
Unzip original firmware once only.
Put the firmware into PDA in Odin
turn off phone and enter download mode.
Connect usb cable to phone/PC
Click start on Odin once you see yellow connection in Odin.
If I was doing this and it was my phone, I would also put the pit file in too. But i shall leave that up to you.
Wait for phone to reboot.
On dial pad phone *2767*3588#
Phone will reset then reboot.
Done.
PS.. do not install custom rom.
If the new owner then wants to upgrade via Kies, he/she can.

I've reinstalled a stock firmware, it all works. It wasn't ever branded and was unlocked when I got it, so to all intents and purposes, it looks like an unlocked, generic S2 now(with UK presets). There was no pit file on what I downloaded -but thanks for your input.....what I didn't do was format all before I tried to install. Once it had gotten stuck, went back into recovery and wiped all these things - now working fine.
For future ref. The pit file, you get from samfirmware.com. Its under flashprograms.
Hope you get a good price for it.

How to flash to Stock ICS update??

Hey guys, new here (obviously). I'm also fairly new to flashing/rooting on Android in general.
I flashed my phone to one of the leaked ICS international versions (when I boot up my phone it says "Samsung Galaxy SII GT I9100" from Gingerbread. I did this a couple of days ago. There are a few problems main one being I can't use the phone app for my phone (ironic).
So since the ICS official version for the US AT&T phone came out, I was wondering.
How can I flash my phone to the stock ICS version? Any help would be great and I hope I did not post in the wrong section :\
Thanks so much in advance guys.
Download KIES, install the proper drivers, plug in your phone, update.
Although you probably messed up your phone flashing firmware for the wrong model....
BTW, you might want to at least make an attempt to read before making a thread. There is a thread already dedicated to upgrading your phone to the official AT&T Gingercream Sandwich update
At least pretend to look like you are genuinely interested. Or you know, follow the rules you agreed to upon signing up in the forums

I don't think the standard method is working. Just shows the battery on screen.
and in response to the kies reply; when I plug in the phone and sync it up with kies, kies says "Your device does not support firmware upgrade through kies" or something along those lines.
In response to the other guy, I'm terribly sorry, maybe you could help by posting a link to that thread? I tried looking around seeing if there was anything related to my issue and I couldn't find anything. Forgive my noob status?
Thanks guys.
I used the method that worked though. Held down power, vol down, and home..
ODIN MODE
PRODUCT NAME: GT-i9100
CUSTOM BINARY DOWNLOAD: NO
CURRENT BINARY: SAMSUNG OFFICIAL
looks like you need to read around and learn how to flash the secondary bootloader for UCKH7. It will change it back to the correct boot screen too. At least, that's what I think. I had to do it the other day after working on rooting the new LE5 stock.
Read the links in Creepy's signature.
To return your phone to I777 stock, flash the UCKH7 CL503881 stock binaries. The one-click downloader is the easiest. You will find the firmware in the Download Repository, link in my signature. This is the package that includes bootloaders and param.lfs.
Edit: I have been assuming you have the I777. This is true isn't it?
After you are at UCKH7 stock, you can use kies to update to stock ICS, or you can flash UCLE5 which is also in the Download Repository, at the bottom.
kk. I think what I'm gonna do is flash is completely back to stock gingerbread using one of his links and odin.
and plug it in through kies and see if that works to update it to ICS official.
Thanks guys! Sorry I caused such an uproar.
Thanks Creepy!! I will do just that
yes that is correct; I have the SGH-I777 At&t Samsung Galaxy S2.
It appears the one click exe that reverts my phone to stock software actually STOPS and "FAIL"s on the part where it's flashing the "cache."
My phone says "Firmware upgrade encountered an issue. Please select recovery mode in Kies and try again."
Fortunately when I went download mode the top right corner says SGH-I777
instead of the international version.
I've tried the one-click several times and it still does not work. :\
Any advice?
Edit: Kies is not recognizing my phone ; "device not responding"
thanks again.
Make sure you have the USB Debugging mode turned off. It took me a few minutes to figure that out when I was trying to upgrade from Gingerbread to ICS via Kies earlier.
Not sure what's hanging it up. From your report, it appears that the secondary bootloader was successfully flashed. Do you recall what other steps completed before the fail?
You should be able to boot into recovery by holding vol+, vol- and pwr. Hold down until you enter recovery. Then wipe data/factory reset. Then try to flash the UCKH7 stock package without bootloaders. The link is in the return to the store guide linked in my signature. Or flash one of the stock plus root packages.
Hey thanks Creepy!
I really hate using the one-clickers, had no luck with 'em :|
I'd much rather use the blank Odin 1.85 exe I have that lets you fill in the files.
If I use that and the ---Return/Unbrick to Stock + Root: I777_UCKH7_OCD_Root_No_BL.7z (This contains the kernel, rooted system image, and modem.)--- download, what do I use for the bootloader slot or do I leave that empty?
thanks

That's a one-click downloader. If you want to flash the full package, there is a tar.md5 file in the Download Repository with everything in it, but it's all in one package, including the bootloaders, so you put it in the pda slot and it's the only file you flash.
In the Download Repository, there are also tars for Entropy512's packages which you can flash in Odin3. They are also one file tars and go in the pda slot. You can read about each one.
I'm not sure you need to flash the bootloaders again. I'd try to wipe data/factory reset and then flash a stock package without bootloaders first.
Applied the one-click with root Flash and now I'm back to gingerbread.
gonna see if I can get ICS working through kies..

Since ur rooted why not just flash the rom in cwm? The official release is found here http://forum.xda-developers.com/showthread.php?t=1650948

thanks bud!
I guess you just drop that file onto the phone using file explorer and USB connection,
then go into recovery to update via cwm?

[Q] Galaxy S2 i9100 stock firmware restore

Hi everyone,
I gave it a shot at rooting my phone and upgrading it from android 4.0.3 to 4.2.1 (rootbox) but I failed miserably. Somewhere in between the phone got stuck at that warning yellow marker and it would only allow me to get into download mode. After trying 5-6 different firmware versions, I finally managed to get one of them to work with Odin and the phone works once again but this firmware version does not work with kies.
I have no idea what the original version was, but I can get all the details from an identical phone from the same operator if you tell me what would be needed. I know it is a silly question, but is there a way to download the firmware from another identical phone used by the same operator?
I want to either restore the phone to a firmware version of local Swiss operator or properly manage to upgrade the firmware to a light version of android so I won't have to deal anymore with all those useless default apps which start automatically and eat up the battery.
I welcome any and all advices.
Thanks in advance.
did you do a full wipe?
my SII is runnning on SlimBean 4.2.2.
just try it
the latest firmware for you S2 you will find at sammobile->firmwares->check your firmware
You can download stock from
http://www.sammobile.com/firmwares/ just search for your phone and carrier then flash back to stock.
As the previous post said did you wipe first? Try a factory reset then flash the rom.

Thanks a lot for the help. With this new firmware on I finally managed to install RootBox 3.8 with Android 4.2.2.
It would be great if I someone would lend a hand in fixing the following 2 small, but quite annoying issues:
1. finding a way to remove 3 of the 5 home screens - I just don't need them and its annoying.
2. finding a way to disable the vibrations that happen whenever I use the on-screen keyboard to write anything

1. If you are on TwLauncher (original one) put two of your fingers on opposite corners or homescreen and then move both fingers to middle. Then you'll see all homescreens and just long press one and a dustbin will appear. Put the homescreens on it
2. Settings > sound > there it will be an option to have you vibrate while pressing and you can uncheck it.
This is very basic stuff, you should explore everything on your phone before asking questions. Keep in mind for next time.
Till then, cheers.

Thanks for the feedback. Be it basic or not, it simply does not work. I used the basic Rootbox as described in this thread.
1. No matter how much I move my fingers on the screen no menu appears
2. System settings >> Sound >> "vibrate on touch" is disabled yet the phone vibrates when I type on the screen keyboard which is really annoying to others if I am in a meeting ... I googled for about 6 hours for a solution and when I failed to find one I posted here. I am sure that the time of everyone here is quite precious I would never want to waste it.

If you can get to the samsung boot logo, then no. Can you access recovery? Or just download mode? If you can access recovery, then factory reset>clear cache>clear dalvik cache and flash one of the firmwares you'd have on your sd card, assuming that you used CWM to flash a zip in the first place (you said that you had cMIUI and rootbox working, go back to one of those.) If you can't get into recovery, then try download mode. You need to keep trying to flash with Odin if you can only access download mode. There's a set of troubleshooting steps to follow if you get another bad Odin flash. Search through my posts for them, I posted them a week back or so.
now trying to install a stock rom
I Can access recovery.. i did all the formatting of caches, i'm trying to install a stock rom now.. what i'm doing is correct or wrong please suggest..

If you're attempting to flash a stock ROM through CWM recovery, stop now. That'll never work. The only way to flash a stock ROM is to use Odin, Mobile Odin (which in your case won't work, requires phone to boot) or Heimdall (I've never used this personally). So if you're using recovery, DON'T flash stock. You have two options to flash a ROM at present:
1) Stock ROM using Odin
2) Custom ROM using CWM recovery.
Done and working Thanks a Lot

I flashed into stock rom XXLSJ variant. phone is working fine but lost access to root. in order to regain recovery menu i rooted my phone.
1. Now i want to backup my ROM using titanium backup. But its stuck at Gaining Root Access Screen What do i do now?
2. Stweaks,Super User and CWM have disappeared how do i get it back??
3. Strange thing Whatsapp is not working Unable to connect using my datapack
4. Can i Software update irrespective of the JB Stock ROMs region I am from.
Good job getting it working again now, time for you to do some reading. Read about what flashing a custom kernel will do for you. Then pick one that's compatible with your firmware and flash it.
