Can anyone link to a guide about restoring my SGS2 to factory settings? I've moved to a Galaxy Nexus and will sell my SGS2 with Envirofone, of the mobile recycling companies.
Much appreciated!
Questions belong in the Q&A section!
Also, the information on how to restore your phone to factory defaults is covered by the user manual and does not require xda-developers.
if you are on a stock rom, unrooted, just go through the settings menu and somewhere in location and security (i believe) you should find what you are looking for. make sure to also format the internal sd card.
For Android ICS
Settings> Backup and Reset > Factory Data reset
Settings> Storage> Erase USB storage
Settings> Storage> Erase SD card
Assuming you have CWM/Recovery installed, format cache, data, system, & internal sd card in Recovery, flash stock rom in Odin then reset flash counter. Done.
If you don't have CWM/Recovery & not rooted, do as Chef Tony said (definitely not an XDA thing if you're not the sort of person who tinkers with the phone/doesn't root or run non-stock firmware).

Sorry I was not clear. I have one of the nightly CM 4.0.4 builds so it will be the former option. Can I reset the flash counter in Odin, and will the Odin flash also remove CWM and reinstall the stock kernel?
Thanks
Can you reset the flash counter in/with Odin ? Um, no
To reset the flash counter, you need Triangle Away if you're running ICS bootloaders, or a jig if you're running the old bootloader. Now that I think of it, if you're running ICS bootloaders, reset the flash counter with Triangle Away first, before you format everything in CWM & before you flash a stock rom as it requires root. Flashing the stock rom in Odin won't affect the flash counter.
Doing all those formats in CWM before you flash the stock rom will remove root (and everything else). When you flash a stock rom in Odin it will include a stock kernel.

Thanks. Didn't know about Triangle Away, great app. Wiped everything in CWM, and then tried to restore two separate 4.0.3 images found here. Both times Odin finished fine, but after reboot the phone doesn't progress past the animated "S". Any ideas?

Hey guys!!!
New galaxy S2 owner. I have done some searching in these forums and the threads answered many of my questions. However, I still have some newbie questions that I found unanswered. Please excuse me if my questions have been answered before but I got tired of searching
Here is the deal:
Yesterday, I flashed a CF Root with Odin3. Then used CWM to flash a wanamlite firmware. The firmware was great but I didn't like that it still had TW. So I dl'ed another firmware to the internal SD card and flashed again using CWM. I then flashed a couple of other ROMS and I noticed that after the first wanamlite flash, the new ROMs were unstable with many error messages that some OS processes have stopped etc.
I got back home, flashed to stock with Odin3 and the phone got stuck at the second samsung logo. I followed some community steps (thanks XDA) like disabling all kies processes from TM, wiping data/cache, then boot in DL mode and flash the stock ROM using Odin3 which worked.
I then Flashed a CF Root again and used CWM to flash a Spike Pure ICS ROM v5 which was great but I get occasional error messages like 'gallery stopped' or some other error message when I try to set contact photos. It just lags, blackscreen then comes back with the 'Unfortunately, the process had stopped'.
My questions: is this because of the previously flashed firmware that this is happening or is it that those ICS ROMs have these issues commonly? Did anyone have this experience before? What do you advice before flashing to a new ROM going back to stock or going straight from the current? Doesn't Odin3 technically wipe everything back to stock?
WIPE WIPE WIPE.
Go into recovery. Data/factory reset.
Advanced, Wipe dalvic cache. Mounts and storage, format system. Its a standard procedure going from one OS to another OS. You can then either flash a firmware zip from recovery or an .tar file from Odin.
Then to be on the safe side factory reset once again.

Wich fw do you have?
Make a deep clean with odin an flash on the latest ics version (lp9 is a good one)..then flash (if you want) a custom rom..
My experience with custom roms: one of the best rom samsung based (ics 4.0.3) is the foxhound greyfox v2..if you want a pure ics rom flash the omega aokp rom (ics 4.0.4)..
Try then to change kernel..siyah is the best for both roms..
P.s. sorry for my bad english
Sent from my GT-I9100 using Tapatalk 2
After LP7 should be staple enough for daily use .However you are using custom roms and you should read carefully each roms thread before flashing .
You are probably suffering from flashing multiple roms and leaving bits behind as well = clean wipe .
jje.
Can someone give me a clear full wipe procedure? I always wiped data/factory rest/wiuped chaceh and dalvik... but what else? a step by step procedure would be helpful!!
I currently have Spike Pure ICS v 5.
What do you mean by Odin3 'deep clean'?

so:
1. Recovery mode > format user data > wipe cache > clear dalvik > format system (from moutns and storage)
2. Download mode > flash stock ROM using odin 3
Did I get it right? Was there something i didn't wipe?
Before you flash a new rom, make sure you answer the requirements.Some ICS roms need to be flashed in specific way.
The way of doing a full wipe is you go in Clockwork mode, wipe data/factory reset, you wipe cache partition, then go to advanced wipe Dalvik and Battery stats, then go in mounts and storage ( i think ) and you wipe the cache from there, but nothing else in mounts and storage.If you wipe anything else there's a high percent of bricking your phone.If this doesnt help you, I doubt that anyone could give you any clearer instructions.
Good luck.
DONT FORMAT SYSTEM.
....................................
Clean Slate for those that balls up the firmware .Or need to return to service or decide if its hardware/firmware problem .
Backup data first if phone is working .
Boot CWM recovery
Mounts and Storage
Format cache data system sd card .
Remove battery
Boot to download mode
Open Odin
Install correct stock firmware .
Followed by root and custom rom if you so wish .

OK im confused now... do I format system directory in mounts and storage or no?

i always do personally.
I got tempted and formatted system/cache/data but now i cannot flash from my internal sd card.. I get errors and 'installation aborted' if i try to do it from CWM... does that mean formatting those 3 means Odin3 is the only way? Cus I'm not home and I don't have odin3 on me.... LOL!
OJ77 said:

Did you format sd card and totally wipe the lot = nothing on the phone .
Backup data first if phone is working .
Boot CWM recovery
Mounts and Storage
Format cache data system sd card .
At this point you have no OS on the phone nor kernel rooted nor CWM .
Hence
Remove battery
Boot to download mode
Open Odin
Install correct stock firmware .

I did a 'full wipe' by doing t his:
1. Boot into CWM: wipe data, wipe cache, wipe dalvik, wipe battery stats, wipe system/data/cache from mounts.
2. Reboot into DL mode, flash stock ROM using Odin3.
3. Repeat step 1
4. flashed spike ICS v 7.3 using CWM. Stable so far.
Thank you!
imho: the most stable ics release is the stock official, but with some.battery issues, my suggestion: stay on gingerbread, find a custom kernel to suits your need,

I agree! I don't like ICS because is still unstable! My battery lasts very short with ICS and the phone overheats.
Moreover I hate the browser! I mean, The Galax S2 with GB still has the smoother browser of all the smartphones out there, and Samsung with ICS update messed it up! Now is laggy with micro stutters! Don't understand why!

You didn't need to go through all that trouble just because you didn't want TW (which I also hate, btw).
You could simply have installed another launcher (such as Go Launcher EX, ADW, etc) from Play Store and, since you were already rooted, uninstalled TW using Titanium Backup afterwards. It has to be in that sequence (install new then uninstall old).
this way you can have whatever ROM + kernel combination you like, and still use whatever launcher you prefer.
how to factory reset stock 4.0.4 and keep root?
hi am quite new to the s2, after rooting with Siyah 4.1.5 i am getting constant crashes and freezes, i wanted a quick step to stop guide on how to factory reset the firmware.
i don't mind loosing all apps and data as i can use titanium also all my main data is on my external sd card. thanks
You are asking to do to different things a factory reset will wipe user data only nothing else , you will still be rooted.
go into recovery and clean cache, daavik cache and then do a factory reset. It will store your phone to default settings for what ever stock rom you are on.
If you format the internal storage, you will lose the rom, root and all data on the internal card. You will then have use cwm or odin to flash a new rom and apps.
Don factory reset jus download philz kernel an flash it via odin or cwm

Someone posted this very succinct summary of the brickbug yesterday in the I9100 General section.
After issues with the stock 4.0.3 to 4.0.4 upgrade, I wanted to root my ATT Samsung Galaxy S2.
I used Odin and UCLE5_Stock_Rooted.tar as suggested on the forum. I did not do a factory wipe- someone said I would not need to since ICS was on it.
Now when it boots I get errors: Logs Provider stopped, android.process.acore stopped, avrcp.service.samsung stopped
I can't access phone apps, call, etc.
When I hold vol +- and power, it comes up Android System Recovery <3e> ... it doesn't say ClockWork Recovery.
I'm not sure what direction to go now. Any help is appreciated.
First thing. Why does the thread title say UNLE5 ?. Second thing, yes you would need a factory reset wipe to fix your errors popping up. But that brings us to the third thing, you flashed a stock image of UCLE5 4.0.3. Which obviously has the stock 3e recovery in it, as you must know our kernels come with recovery installed and when you flashed that stock image it flashed the stock kernel that comes with 4.0.3 . Which takes us back to your factory reset/data wipe you need to do. You are now on stock ics kernel, which has been confirmed to have the EMMC brick bug. Which is just a fancy way of saying that if you do a factory reset/data wipe when on this kernel, it could hard brick your device. So if you want to stay stock with everything, just flash a custom kernel(siyah.tar file is easy to find) with Odin, then reboot into recovery and do a full wipe. Then simply flash your UCLE5 image again with Odin and you're good to go. But I would suggest just using a custom kernel and getting off the stock kernel, don't want to accidentally forget and brick your device.

Thanks- sorry about the typo in the title... I meant UCLE5. I was able to get rid of the errors by clearing the data on those items in the application manager. Thanks for the info on the custom kernel... I wasn't sure which to use for 4.0.3.

All good I'm glad you got it sorted.
Updgraded to Jelly Bean 4.1.2 via Kies. Un-rooted, stock SGH-I777. Stuck in bootloop now at AT&T logo. I already did the wipe data cache in recovery mode with no luck so it leaves me to factory reset as my next option. I've spent several hours browsing through the forum already. Do any of the below allow me to keep data?
1) Use Odin and stock firmware - downloaded the UCMD8 tar file
2) Root, install kernel w/ CWM to use backup functionality. (http://forum.xda-developers.com/showthread.php?t=1285894)
Just need a point in the direction I need to go, I'll handle the rest.
If the result is all the same (i.e. data loss), I'll use this issue as an opportunity to put a custom ROM on my phone.
Thanks!
Yes, most likely a wipe data/factory reset performed in recovery would correct the problem, but you will lose some system data. Which specific things are you worried about losing? You won't lose your photos, or any data from applications installed from the play store.
You are going to have to perform a wipe data/factory reset to use odin and the stock UCMD8 firmware. In fact, at this point it is probably the only way out.
U could try to re Odin the firmware first. Not sure where ya got it from, but it should be a no wipe. But if that doesn't solve ur problem, then ya have a few options--- Odin a custom kernel (like AJK), and then u could Mount usb storage through recovery and backup ur stuff to ur pc. Then try to see if it will boot up without looping. If it still loops then u need to go back into recovery and wipe data/factory reset. Reboot. And it should be good. Or if ya don't care about ur data, then just reboot to recovery and wipe data and reboot.

Hi, my S2 is running the spanish 4.1.2 that was flashed with ODIN a long time ago. Today it just died, when I try to switch it on it just stuck on the samsung logo (after the cool sound and animation).
I've tried to do wipe cache partition, no effect.
It's not dead. Unplug battery then put it back, then enter odin mode or recovery mode, reset rom. You could do odin on pc or recovery on Phone

@nupity maybe you can flash an flashable kernel/recovery through odin so you could also push another rom to your phone, flash it and easily backup your data. You can try siyah flashable kernel for odin or maybe from philz
Siyah, philz or dorimanx 8.43 kernel

I thought about it, should I flash through odin the rom that it's running right now? It should save the data and make it run right?
And then I will backup and move to a new rom.
@nupity you can try it BUT i am not sure or it formats data/factory reset also thats why i suggested to flash an recovery to flash another 4.1.2 stock based rom. You can google it about odin to be sure. I can't google it now since my tab's browser is bugged :/ and i don remember anymore from when i had the s2 or it wipes data also. I wish you luck with this

ahh okay nupity Maybe there is something with your existing apps what you had first. Try to go to Philz recovery and wipe cache/dalvik cache. If that doesn't work and it's still stuck then you maybe need to try to flash another 4.1.2 stock based romand see if it goes then so Download the rom, Format system, Cache and Dalvik cache.

I have access to the phone's files through Droid Explorer. Where can I found their data?
@nupity its in the android/data folder but if you have recovery like i said just do advanced backup of data partition and use nandroid backup manager or something like that to get the data. Or you can just take the folder I guess :/ i am not sure anymore about the folder since i am 2 months without an android phone
