Samsung Galaxy S2 Freezing and Rebooting - Galaxy S II Q&A, Help & Troubleshooting

Hello guys
I have samsung galaxy s2 I recently buyed it, phone sometimes gets in reboot loop or it just hangs freezes with screen and if you do not restart it it will stay blocked
I have tried all roms and kernels but no success currently I have the latest samsung official rom
Is there a way to fix SD card or do something like full format because format and wipe with CWM are useless
I need this fixed ASAP because its eating me, and can it be a battery problem or what is the issue?
Sincerely yours
BETIMI

If u tried all roms with wipe etc its a hardware issue.Go to Samsung centre or from were u bought it and replace it

Remove you're sdcard first and do not use it until you sure problem is fixed or still happening...
Flash stock GB ROM using Odin.

How to remove SD card, I dont have an external sticked on it just only the 16GB Phone storage ?

Just go through the rest of the work, remember either the emmc format or sdcard format will work, depends on version of Cwm so don't worry about that error when you get that.

I have tried everything with roms but no success it happens again...
What should I do more ?

If you really formatted system, and flashed a stock GB ROM, and didn't mod it later, with kernels and stuff and still got issues, go to Samsung repair.

[Q] Unstable ICS ROMs (tried many...)

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

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 .
jje
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 .

Thanks...
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,
GT-I9100, official 2.3.6, hardcore's Speedmod

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.

big problem with cwm and odin

Hi,
First time it happened. tried everything but still cant fix it.
after a month or two on MIUI, I wanted to move to AOKP JB.
As I always do when switching ROMs, I backed up everything (efs, pictures, apps with titanium, etc) and format the internal sd card within the os to get rid of all the junk.
Then went into CWM (siyah) and wiped data and cache.
And now for my mistake, I foramt the /system instead of / cache.
So now, when Im trying to install the ROM as a zip file threw CWM I got an error 7.
When trying to do it on ODIN, it stuck on 'factory fs', 'cache', or 'boot'.
After some time, I got the "Firmware upgrade encountered an issue" message.
Then got rid of it after somehow succeeding installing a different cwm (the stock one) but nothing worked there either, exept installing the Siyah kernel zip from there.
What can I do now to get my phone back alive?
THANKS :crying:

I jumped from S1 to S3, but I'm sure it's applicable. You need to flash via odin stock rom that originally came with your phone. Then root then flash custom rom. Odd tho in past I've done the 5 formats, boot, cache, data, system, sdcard then while still in recovery flash rom. Good luck

The problem is, I really cant remember what was the original ROM version. I bought it end of june 2011.
I cant even remember if it was a UK ROM, or an open europe one, or anything else.

Soft bricked.. I guess :s

I had ICS.. backed with titanium and upgraded to JB with Liquidsmooth's rom... however I failed to read that titanium backedup contacts couldn't restore from ICS to JB... after reinstalling Liquidsmooth I thought the error might be with the ROM so I installed Omega's JB rom... nice bootscreen... pity it stayed in a bootloop... I then reinstalled it from cwm after removing the battery (a few times) and getting into recovery.... however it remained the same...
so.. I get into odin.. PDA -> ChainFire's "CF-SGS3-CWM-v5.5-v1.5.tar" worried that all I've don'e is put a ics kernal into a JB rom... I boot into recovery and install an old (possibly original root) ROM... now it boots past the animated logo just stays on the static -Samsung- logo... I can boot into odin.. not tried to boot into recovery...
but I don't have a recovery rom... (I have searched)...
could someone point me in the right direction please
Thanks
Have you tried wiping cache and dalvik, maybe try factory reset.
If all that fails this is what I do:
Boot into recovery
Go to mounts and storage
Format cache, System, data and internal sd card. (of course you will lose all data)
Then flash a full stock firmware package through Odin.
Done

I found a stock 4.04 (ICS) rom... still soft bricked... I'll wipe everything except internal SD card... see if that works.. else guess I got no other option :s... I am pretty much backed up so I'm not completely fussed.. but I know there will be something that was missed...
didn't have to do a full wipe... but when I power-off it still reboots... I have to remove battery to power off?
Just do a wipe from Recovery, often the problem then not.

[Q] Please help my device wont get pass the gt i9300 screen

Hey guys this is my first time messing with custom roms and my biggest fear has come true i think i bricked my phone, at least soft brick.
here is what happened:
I decided to flash supernexus 5 rom and everything went well, however my wifi wasnt working i tried to do a nandroid recover from a nandroid backup that i had from a while back made with the same version of cmw but it i got the message "no files found" even when i had put the folder with the recovery in my internal storage in the cmw folder. I decided to do a factory reset, wipe cache and dalvik cache but this didn't solve my problem with cmw not detecting the files then i went on and did this i went to mounts and storage as i read on a thread that mounting and unmounting everything solved the problem for a guy but this did not help either, then i went to mounts and storage and formated cache, data and system as shown in this youtube video http://www.youtube.com/watch?v=ZCoI62PG7jE&feature=g-hist after that i tried to rebot the phone but it wont get pass the inicial galaxy s3 i9300 screen, i tried whipe data cache and factory reset again but i still can't make it boot ,I can get to recovery however it still doesn't see the folder that i have there. If i connect the phone to the pc it says installing drivers for the device but it fails and i can't see the phone anymore as connected.
Please help me you have no idea how much i saved for buying this and i don't want to loose it.
this is the version of cmw that im using CF-SGS3-CWM-v5.5-v1.5

You formatted system so you have no os to boot! Flash stock Rom with Odin.
Nb.......if you are using cm10/aosp you need to flash an ics Rom, let it boot, and enable wifi before then going on to flash the Rom as wifi won't work coming direct from jb Rom

yes it was the same version only thing is that when i made it i have rooted with cf-root 6.4, but after flashing the stock elk4 leak i used cf auto root and then installed the recovery on its own but is the same version.

hmmmm......not sure what the problem is then, only thing I can suggest is flash the cf root again(not the auto one) and see if that sorts it, but I would move that backup back to its original location first
thanks again!! i will try flashing it again.

It's just a shot in the dark, but it's the direction I would head in if it happened to me......or I would just abandon the backup and start afresh !

I9300 battery died now bootloops

Hi guys little intro
Samsung galaxy S3 I9300 International
Running
TWRP recovery
Slimbean android 4.3
Basically what happened is the battery died on the phone so i swapped it out for a charged one and the device just bootloops on the slimbean logo. I then went into recovery to restore from a backup and after the restore it said "This device does not appear to be rooted would you like to install supersu." <-- alarm bells?? so i click yes, and now it doesnt even boot up the slimbean logo it just sits at the samsung one.
I have tried
Re rooting using cfroot
Reinstalling recovery
Reinstalling the rom
Restoring to a backup.
Nothing is working? is it possible for phones to throw wobblys and unroot themselves? which would explain why i cant load a custom rom?
Whats worse i cannot for the life of me figure out why just pulling the battery would result in a bootloop?
#
help pleaseeee
An instant shut down will usually result in data corruption, first try clear cache and dalvik, next a mega wipe script.
If that also fails then probably best to flash a stock rom using odin on your pc. You might need your efs backup if that partition was damaged.
Managed to resolve the issue by first re rooting with cfroot then installing twrp then reflashing the ROM, unfortunately my micro SD card got corrupted over 30gb of music and data gone, not impressed, also lost my nandroid backups and my titanium backups
