[Q] Galaxy keeps rebooting after flashing ics - Galaxy S II Q&A, Help & Troubleshooting

So I flash the Ics update (LPQ) last friday and all went well, my phone was working perfectly. However on sunday my phone kept freezing and the only was to get it working again was to pull the battery. So because of this i decided to go back to GB and wiped everything and flask a stock firmware (KI8) which is my carrier firmware. Now my phone keeps turns off every 10 minutes or so any it is really annoying. It only seems to happen when the phone is not plugged in to charge and I have tested it out and it doesn't tend to happen in flight mode either. At the moment I have wiped the phone completely and haven't even installed an app yet it is still happening. Has anyone got a clue what this could be as its driving me mad.
Thanks in advance

I have the same problem, i updated to ICS and now my phone reboots every 2 / 30mins.
I tryed lots of roms and now downgraded to a 2.3.3 stock rom, with re-partition, no SDcard .. but still ... it reboots itself a lot .
The strange thing is that it reboots when left alone, the sgs2 can stay up for 3h+ when it plays music on GoogleMusic ...
Oh, and i also tryed with a new samsung 2000mah battery kit, still no changes, so it's not a battery problem

I had this problem with GB 2.3.5 stock firmware. After flashing custom ICS - Lite'ning Rom - http://forum.xda-developers.com/showthread.php?t=1095274 , the problem disappeared. Of course I did full wipe of device before flashing.

Thanks, Ill try flash lightning later when i get home. As i think that it is something to do with the radio I have also tried flashing a new modem (KE7) but that did not solve the issue either. It there any app that can monitor processes so that i can look at what is happening just before it turns off.

I had this when I was using MIUI. I flashed Spikes Pure ICS yesterday and haven't noticed it since.

Strange, I had this issue on GB, and not on ICS. Try flashing some different roms, full wipes of course, and see if that helps

i did a factory reset by using the *2767*3855# command , then i went to the recovery to format data/system/cache/sdcard/emmc .
Still, no luck and getting reboots

Last night I flashed both lite'ning ron and Check rom. Did a full wipe before both and I am still getting reboots and freezes. Think Ill have to get a jig and bring it back to the shop

So just to update. The latest think i have tried is changing the modem to KE3 and I tried the speedmod kernel and the syriah kernel. Still having the freezing issue. Have also tried a kernel cleaner but to no avail. Anything else I should try before bringing it back. Thanks

Why dont you try to install a stock rom, then root it, and within CWM recovery wipe everything, then reinstall your stock rom thru odin

Have tried flashing the stock firmware 2.3.5 KI7 and wiped the cache,the dalvick cache and factory reset the phone before but that didnt work. Is there specific firmwares that will wipe everything?

Corrupt SD can sometimes also cause random reboots. Do you have an external SD on top of the included internal SD? Try formatting them both. Start fresh.

i agree with you i tried this method last year and it worked,, you should try this and if doesnt work format your phone system wipe data, wipe cache , wipe dalvik for a very fresh start..

Yes I thought it could have been the sd card to so I removed it from from the phone and formatted the internal memory, then wiped the dalvik cache, the cache and the phone and flashed a new rom but my phone started to freeze after about 20 minutes. Its weird originally my phone was Freeze and wouldnt wake from sleep, then it would just randomly reboot and now its back to freezing and not waking from sleep

I would try KH3 rom. For me that was the most stable GB rom

Phone randomly rebooting, no mounting/formatting sdcard

Hey guys,
need some help here. Some time ago (about 4 weeks), my phone started to crash randomly. Example: I was listening to some music, suddenly the music stopped. I thought I accidentially unplugged my earphones, but instead, my phone rebooted, without any further notice. Since then I got those reboots several times a day, not only while listening to music, but surfing the web, doing literally nothing (during work, I suddenly hear my phone reboot while idling in my pocket) or accessing any app installed on my device.
I am rooted and use a custom kernel and a custom rom. At first I thought, maybe there's something wrong with your kernel/rom, so I updated those. (Was on LeoMar75's Revolution Rom 2.5 -> installed 2.7.1; updated to latest Siyah kernel, I think it was 2.0.1 or something) Of course, I did a full wipe, but it didn't help at all. The first day everything looked fine, but then the phone started crashing again. After some more time, I changed to CheckROM RevoHD 2.0 and then 3.1.1. and changed kernel to Siyah. 2.1.1. then DK-kernel 2.1. Always the same results, always random reboots.
In the end, I thought to myself, that custom rom/kernel might not work properly on my device, so I went into cwm, wiped everything, installed stock kernel and flashed original rom via Kies. But, I STILL got those reboots.
Just for the record, when I say "wipe", i mean going into CWM and wiping cache and dalvik chache, batterystats, doing a factory reset and formatting /system, /data, /sdcard and /emmc. But the last time I did this, I noticed that i could not format /sdcard, I could'nt even mount it. I'm on CWM 5.0.2.7. now.
After that much of annoying text, my question is: Am I doing something wrong or is my phone broken? And if I'm doing something wrong, please tell me what, 'cause I'm kinda desperate here...^^
Looking forward to your help
Check to see if any apps are installed to external SD. If so, move them to internal storage. Also, in my experience, uninstall Dolphin HD if you have it on your device.

Hi SaneinOne,
I have no apps installed to my external_sd. I only store some music there. Additionally, I delete all android related folders from my external_sd before inserting it into a freshly flashed phone.
About Dolphin HD, already heared of that, tried it, didn't help.
But thanks for your help
No clues? C'mon guys, please, I'm desperate.
Maybe it a hardware problem ...
Try using warranty.
Dont know what your rom is but .
I would clean phone and start over .
Boot recovery
Mounts and storage FORMAT cache sd card data system
Remove battery
Boot to download mode flash stock rom via Odin .
Clear Custom rom counter with USB jig if needed .
Return to service centre .
jje
tEsT_MaStEr, JJEgan,
thanks for your replies.
I flashed everything back to stock and reset the flash counter with my friends' jig. I returned the phone to my store, they said they'll send it to Samsung to check it up. Let's see what happens...
Yay, 6 weeks without smartphone...

[Q] WiFi suddenly stopped working

I've tried it all folks. New kernels, factory reset, different radios, different ROMs. Every-thing. The WiFi will turn on for a quick second and I will get an error message "Unable to scan for networks" and then the Wifi will just turn on and off on and off over and over again. I've even deleted the files in the data/dhcp and data/wifi folders. Rebooted, still same issue. I've deleted the files and flashed a kernel and rebooted, still same issue.
Of course I am still in contract and will have to purchase a new phone outright from Verizon if I can't get this issue resolved......
I don't know what else to do here.....
Did you try formatting data and system before installing a new rom from recovery? If that doesn't work i would say its a hardware issue. You're not restoring system data with any backup programs are you?

I've wiped pretty much everything known to man on the phone. The ROM installs are all "fresh" I haven't tried to install any APPS on the phone. Just wipe everything, factory reset / Dalvik Cache, all of it... install fresh ROM. Try to turn on Wifi, phone boot loops. No matter what ROM I install, still same issue with Wifi / boot looping.
Well guess we can close this out. I went out and paid full boat for a Samsung Nexus since I couldn't fix this issue.
I'd like to reopen this topic. I had been running Bamf Forever 1.10, but last night I decided to try another ROM because it's been running really slow for some reason.
Did a wipe (factory reset, Dalvik cache) and installed Thunderstick. Now WiFi is broken -- the exact same problem as described in the original post. I tried flashing a new kernel and new radios, and cannot get WiFi to work.
Does anyone have any suggestions? Will flashing back to stock ROM/unrooting help?
Thanks!
@ajoesq I had the same problem when i installed thunderstick thru boot manager. My wifi stopped and I could get it going on my phone rom. So i booted back into thunderstick and wifi was working. Booted back to hte phone rom then into recovery and then i flashed my phone rom again without wiping or anything (Thunbershed V1.2) and it worked fine. wifi started agian.

Run a logcat when you try to turn wifi on. Put the output on pastebin.com and post the link. This might tell us what the problem is.
I'd make sure that the radio(s) were at least at the minimum of what the ROM called for.

[Q] I717 Not Operating Properly

Hi,
I have a galaxy note i-717m. It is lagging very badly, even if i tried to clear cache, dalvik cache, and wipe data/factory reset.
I tried to restore it to a working rom, it succeeded with less lagging. However, the phone freezes screen when I try opening any apps and will reboot after sometime.
Could anyone please help?
Going back to stock cannot help either.
Flash the correct modem. That is a Bell phone originally, right?

Ok i will try flashing the bell stock modem as well.
flahsed stock bell modem by cwm, sucessfull, but cannot fix the lag
Just don't do anything flashing-wise. Let the rom and modem settle for a little.
I tried letting it settle for the whole afternoon.
I still experience freezes when i try opening some apps and everytime i press back to exit an app.
The phone reboots sometime, sadly i don't have a tjag box.
I have gone to recovery and show log.
Its shows: failed to open /sys/class/android_usb/android0/state: no such file or directory.
Dunno if that matters.

Is your rom stock? Or did you flash a rom from the development section?.. The lag your talking about?...why are members talking about your modem for lag? am confused?.....What exactly are you looking for? can you flash a rom? if so stay away from Jelly bean based roms right now,seems to have alot of bugs..I tried most of them.and users that arnt that experiencedvshouldbstayvaway from them and just stick to a good stable ICS rom right now...your lag will be gone and your phone should run alot faster you will see improvements right away
I restored to the bell stock rom and modem
The device can boot, but it freezes when i press the back button, trying to quit an app.
thank you for your advice, i will try getting the canadian custom i717 rom

Crashing since yesterday's update?

I have been using Omega rom for many months however recently the phone started to lag very bad, so I tried updating it to the latest update of Omega,however there was no improvement even after a clean fresh install.
So I decided to go back to a stock rom not realising I needed certain functions that only a custom rom provides.
However ever since the loading of the stock rom and re-rooting the phone, every custom rom I have tried, Omega and Sensation, after start up when installing the rom, within 5min the phone just crashes and I cannot do anything unless I take the battery out.
Why would this crashing keep occuring and what could I do to resolve this issue?
Just tried tried flashing Sensation again and installed fine but within 2mins of completing the install, it crashed and I had to take out the battery and reinsert to finish my first time setup, which this time completed.
I then allowed the phone to reload apps trhough google play and within 5mins of installing it again crashed although the charging icon is moving but I cannot select anything on the screen...

did you try full wiping ur s3 and then reinstall omega

When you say full wipe, do you mean through CWM?
I did wipe data, wipe cache, wipe dalvik.
Installed rom will full wipe selected.
After installing, wipe data and cache again.
Still crashing...
Omega problem ask in the Omega thread makes a lot more sense .

I had the same issue with Android Revolution.
Since reverting to stock rom, things seem fine now...

i9300 sleep of death issue

I'm helping a friend with her S3 i9300. It was running very sluggishly and starting in the last couple months she's been having a sleep of death issue.
It works fine (albeit slowly) while she's using it but when it sleeps for more than 10 minutes it doesn't turn back on without a lot of trouble or a holding down the power button and hard resetting. Every once in a while it only boots if I go indirectly through download mode.
I've confirmed with the play store app that she does NOT have the "insane chip" involved in the SDS issue. I've also factory resetted, rooted, tried flashing a custom kernel, a custom TW ROM (S5 sensation) and now an AOSP ROM (resurrection remix) and the problem persists.
Looking at other users' suggestions I took it apart and cleaned/played with the power button, even replacing it with the one from my old t999. Still the same.
I'm at a loss at this point. Has anyone run into this issue and found a fix I'm missing? Thanks for the help.
Have you already tried to format system partition (sdcard 0) via recovery?
After that you MUST flash a ROM, cause there is no system installed.
So, try to do this and let me know.
Else you can try to do a MEGA/SUPER wipe.

Thanks for the reply. Before flashing any ROMs I've always made sure to do a factory reset and then individually wipe System, Data, Cache, and Davlik Cache even though I know I'm duplicating some of the wiping. Unfortunately that did not work in this case.
I'll give the MEGA/SUPER wipe a try and report back.
Thanks again.
Looks like MEGA wipe didn't do the trick either. The phone is on NA8; is there a newer baseband I can try? Not sure what else to try.
At this point I'm thinking it might just be a hardware issue.
Flash the latest stock firmware from sammobile then factory reset, remove sd card and sim then test with a different battery.
If still the same then it is a hardware fault, motherboard/cpu.
