A friend of mine recently updated her Galaxy S2 from the stock GB 2.3.6 to AT&T's ICS update. According to her it's ruined the phone and she wants to go back. I'm assuming it's as simple as flashing a stock GB 2.3.6 ROM with Odin onto the phone but I can't seem to find that ROM anywhere. I flashed the hell out of my old Galaxy and have already flashed my Galaxy S3 a few times, but I've never worked with an S2 before so pardon the noobness

If you wanna go back to stock gingerbread here's the link. Please read the entire post, its very easy to do. I've done it a few times when I've managed to soft-brick my phone.

Edit: There is a bug in stock ics kernel that seems to mess up the phone. Since you're not rooted double check with a recognized dev or contributor to make sure this will work.
Doing a data wipe or factory reset from within recovery with stock ics kernel can result in a bricked phone as a result of the emmc bug - so avoid doing such as long as the stock ics kernel is on the phone.
First flash back to a gingerbread kernel or a safe ics kernel before doing any wipe or factory reset.

Hey everyone
A little while ago I jumped on the ICS bandwagon and flashed my villainrom 2.5-toting Optus i9100 to WanamLite 8.9, via CWM Recovery.
its been buggy as hell and the phone has turned to garbage ever since, with random freezing, touch input not responding, et cetera.
my question is - should i have flashed to one of the leaked samsung ICS ROMs via ODIN before updating to wanamlite via CWM Recovery?
i remember back in the SGS days, when moving from 2.1/2.2 to 2.3, you had to flash a generic 2.3 ROM via ODIN before you could flash a custom one. flashing a gingerbread darky's ROM over a froyo custom ROM directly using CWM caused all kinds of problems.
now that the official Samsung XXLPQ ICS is out, i want to flash to a pre-rooted version of it with CF-Root kernel (the ones that wanam himself has uploaded). but should i flash via ODIN to an official ICS first, and then root + flash the wanam custom version, just like i had to do when going from 2.2 to 2.3 on my original SGS?

If i helped please consider clicking yes,thats what my dog always wanted ! Sent from under my bed
Sorry for the previous post i clicked it while it ways empty by wrong
Just get ur phone into download mode and flash the stock jpq
After that do wipe cache and factory and ull be good to go
isn't the problem with doing that the fact that the bootloader will be upgraded as well, meaning i can't reset the flash counter with my USB jig anymore?
my question is - should i have flashed to one of the leaked samsung ICS ROMs via ODIN before updating to wanamlite via CWM Recovery?
Not really needed .
But this is what i always do with any major upgrade or new custom rom .
titanium backup and nandroid backup
Wipe.format system data cache .
Install stock rom of same version
Root with CWM and Root kernel.
Flash new rom .
result no problems .
jje
Restore backed up apps .
Hey guys
My S2 was preloaded with ICS 4.0.3 when i bought it. However i have noticed problem with many of the HD games, they run for sometime and crash...
My question is, how can i downgrade to gingerbead 2.3.6.?
I did find my region 2.3.6 firmware on sammobile..so if i follow the flashing steps from odin..the downgrade will be done successfully?
Also how safe is the process?
Also i would like to know how to take a back up my phone in the current state? So if something goes wrong or if i am not satisified with the downgrade, i can go back to ICS 4 i.e. the same condition my phone was when i unboxed it?
Some suggestions and answers would be really appreciated
Thanks
You cant backup your current rom without rooting it. here is a good vid on how to root a galaxy s2 http://galaxys2root.com/galaxy-s2-root/how-to-root-galaxy-s2-i9100-icsandroid-4-0/
You will need to back up your phone using clockwork recovery
You can however download the latest rom using Check Fus you can find it here http://fus.nanzen.se/ This should be safe. this video here will show you how to use odin to flash a stock kernel http://galaxys2root.com/galaxy-s2-unroot/how-to-unrootunbrick-your-galaxy-s2-i9100-ics/
you can always go back to ics if you do not like the GB stock rom
Hope this helps

Yea flashing through Odin is safe. Just don't mess with the repartition box or pit files unless you are 100% sure what you're doing. And if you're stock you can backup your device through Kies.

Hi guys
Bascially I need to have Android 2.3 on my Galaxy WiFi 5.0, I need HD video etc so im running into a problem. I have installed Eryigit-GB-2.3.6 G70ZCKPA Galaxy Player/wifi 5.0 ROM at the minute but I really would like unmodified 2.3 ROM not this one yet when I try to use odin to flash this ROM: Galaxy Player 5.0 Gingerbread KPH 2.3.6 it says every thing went ok but the device bootloops. Now Ive tried it with just the ROM and then Flashed the Kernel INTL one and it still does this?
Any help guys thanks
Please don't reply if all you have to say is "why go back to ginger bread when there are ics roms" ino i developed a couple of them i just need helpful answers thanks

Well the obvious first thing is that the stock kernel does not support ext4, so it will not boot without access to /data and /cache. Try going into stock recovery and wiping data. If it just gives you a bunch of errors, you need to flash and *repartition* in Odin. Then try wiping in stock again.

Thanks mate i flashed Pit file along with stock ROM and it worked cheers to you
Hallo everyone!
So since a week ago i'm a proud owner of Samsung Galaxy S2 (yay!).
It had Android 2.3.5 at the beginning so 2 days ago i've updated it to ICS (4.0.3). I've updated it via ODIN (since it couldn't find updates via KIES or by air) with a official ROM (if that's what it's called) from samfirmware.
Since then my phone heats up a lot more compared to 2.3.5 , i don't know how's that possible but i haven't installed any new apps or used the phone differently since the update. I know it's normal to heat up when playing games but even if i'm browsing the web it heats up a lot. I haven't this problem with 2.3.5
Any suggestions?
Go back to 2.3.5 and wait for JB.Or try custom rom.

So it's a common issue?
Hmm.. This is weird.. I'm having the same issue, but I'm having it with JellyBean ROMs.
For ICS the combination that works for me best is Cyanogenmod 9.1 and Siyah Kernel. If that still heats up, you might want to try some different modem and check out if any of them works for you. I think the stock XXKH3 modem helps.

As you might red above i'm a total newb to Android world atm , i just learned how to flash few days ago, i'm not going to mess with new modems etc. (for now). Do you guys think that if i upgrade to that leaked 4.1.2 , that might fix the problem? Also i didn't do factory reset after the upgrade to 4.0.3 because some other user from other forum told me that if i install the official 4.0.3 rom from Samsung - there's no need to do factory reset.
I would have done a factory reset,but thats just me.ICS was overheating my wifes phone,but it was the 4.0.4 thats worst.
If you are flashing modems,you should root first and backup your efs folder......and make a nand backup.

As i mentioned i won't be flashing modems and such. What would you suggest me to do from that point (aside from downgrading)?
You can only downgrade to GB.I detest ICS(rootbox was ok),so I went back to GB.
But now I use vanilla rootbox(JB) with dorimanx kernel.
Only problem Ive seen with this so far is the bloody volumes far too loud when I press keys(had to switch it off).
Anyway,whatever you do make sure you get rooted and backup your efs folder.
So i just upgraded to JB and we'll see how's it going.

UPDATE: So i've upgraded to 4.1.2 (JellyBean) , haven't installed any apps and for about 10 min. of browsing the web it jumped from 31°C to 37°C. What should be the average temperature of SGSII while using it (not playing games)?

Ok dont bother then.....its no skin off my nose.
I went to samMobile firmware site and going to download, 4.0.3 ics or the GB firmware. I currently have ics 4.0.4 and my phone keeps going into SOD and i have to remove battery to turn back on, so can I flash with oldin one of the other version of firmware to downgrade to 4.0.3 ics without hurting my phone. as a noob and i have been trying to read posts. 4.0.3 befoore the upgate was running good.
You can flash the 4.0.3 UCLE5 from SamFirmware using odin. The file contains everything, including bootloaders I'm pretty sure, and is straight stock, not rooted. You will most likely need to perform a wipe data/factory reset, and there could be some risk involved due to the possible eMMC superbrick bug in the UCLE5 kernel.
Another possible route would be to flash UCLE5 plus root from the development section of this forum. It is a bit safer since the bootloader is removed. After that you should also install a custom kernel to get away from the stock kernel.
Thank You will have alook at JB roms. Hopefully this will fix the SOD issue Att and samsung are pissing meoof, on my 3rd phone with same isssue.

My understanding is that the sleep of death problem is a firmware issue in the 4.0.4 distribution. If that is the case, replacing hardware will not solve the problem. Or maybe your replacements have been for another reason? Anyway, I have never had stock 4.0.4 or stock 4.0.3 on my phone, but I am running a JB rom (SHOstock) and have never had the SOD issue.
stock 4.0.4

Can anyone confirm if this process works coming from stock 4.0.4? I have a friend who asked me to root his device and I would hate for something to happen to someone else's phone. If it's my own, I would just not sleep all night until I've found a way to bring it back.

Just like anything else , it works the way it's supposed to if directions are followed and appropriate reading is done.
