Samsung Galaxy S2 i9000 - CM7.1 Keeps "resetting" - Galaxy S II Q&A, Help & Troubleshooting

Hi there
I am relatively new to the world of custom ROMs. I have an S2 Galaxy and I have been using CM7.1 without fault for a few months. The other day, without any explicable reason, my phone rebooted. All good so far. What happened after that, though, has got me stumped and is driving me CRAZY. Heres what happens: The phone "resets" to a backup i did at the end of July. When I say it resets, i mean it literally wipes everything and reverts back to the previous backup. Ok, so this is still believable. But... now it goes into this GroundHog Day scenario several times a day, reverting back to the same backup. Yes, it means I have to update the same apps which I delete as soon as it does it. I can wipe my cache, i can reset to factory... I can flash other ROMS - which I get told is done successfully - I can physically remove my SD card... I can re-flash it through Odin... down to kernel level... and every time i reboot... it comes back to the same darn backup, even with the SD Card sitting on my desk. Is there ANYONE out there who has had this happen before? Its driving me nuts. Is there perhaps a way I can totally, completely and utterly WIPE my phone and start from scratch? Any help would be MUCH appreciated!

[URGENT] help needed with randomly hard resetting fuze.

every few hours my fuze becomes super slow, and power cycling it resets the phone back to factory settings, aka hard reset.
so i have found out by vigorously searching the forums, that my internal storage may have some corrupt sectors that i need to deal with using RAPHDIAG.nbh
it seems i must have this file on my sd card and then hard reset the phone and it will go about reformatting the internal storage after which i can reload the rom - IS THIS CORRECT? i have never done this before.
also my case is stuck to my phone so i cannot remove my sd card, in which case if i do said procedure, can i then active sync to reflash a good rom onto my phone? if not should i load the rom onto the card as well before hand so then i can use the flash by sd card method?
please help i need to get my phone working asap.
DId you try installing an official build and then going back to the cooked ROMs? That solved it for me long time ago..
no i did not. i was too impatient so i went ahead with the raphdiag.nbh, which took about 4 seconds to flash the nand. after that i reloaded tael, and it seems a bit faster and hasn't hard reset in the 4-5 hours that it normally does.
if it does this again, i might revert to the stock and then redo the custom rom procedure.
thanks and i will keep u updated.
Hope it works out for you.
A similar thing happened a flash and a couple of hard resets solved it for me.
Happened to me also a long time ago with one of the first NRG Roms.. The cure to my problem was flashing back to a stock AT&T rom and then reflashing the new rom you have again.. Hope this helps
i have to say the xda community is the most helpful i have ever seen, and for that.. kudos community, kudos.
so far i have reformatted the nand to fat using the raphdiag.nbh, and it seems as though that made the phone faster, and has been successful in solving the problem for this 1 day, i'll probably not customize my phone for a few days until im sure its fixed, or else its a trip to stock and back.
PS
since it made my general operation faster, im wondering if its any harm to keep fat formatting the nand on a regular basis before every new rom flash that i do on there? would that damage the system any?
also we need to document this raphdiag.nbh procedure so that people dont have to hunt for hours and then take a shot in the dark figuring out how it works (it took me 20 minutes to realize there was a selectable operation on screen)
weird things happened today morning again. going to revert to stock and then back.
im assuming i dont have to go to the stock spl, just the rom and radio.

[Q] I have searched enough: Recovering Backup with CWMOD

OK:
Briefly, Running fine on VEGAn 7 RC 1 with Pershoot's latest. When the Tab was running and booting, I made a full backup in CWMod.
Screwed around with some permissions and once I rebooted, ended up at VEGAn Tab pulsating Boot Screen. It would do its thing for a minute or so, screen would go blank and then return immediately to the same VEGAn Tab screen (i.e., not a full boot).
Not a problem, right? I just booted into CWMod, cleared out everything and restored my earlier backup.
No go. Same loop at the VEGAn screen.
I searched the forums a lot, so either I am not very good at searching or this has not been addressed.
Advice would be appreciated, as this is not the first time I have been here and want to learn if there is a way to repair it (obviously, I can reflash ROM+Kernel) restore via Titanium and only have a little manual recovery left to do.
Thanks!
I had the same thing happen to me while i was changing around roms. I know its not the exact thing but regardless. Anyways, try mounting your tab in cwm as USB and pull your back up off the tabs memory. Go back to cwm and wipe everything, then repartition to advised settings. Remount your tab as usb and put the back up back on your drive and restore again. It may work.

If its something simple, clearing the Dalvik Cache in CWM might fix it.
I appreciate the ideas. Unfortunately i have tried then all. One of the times this has happened i was messing around with the old two taps xoom. Of i knew anything about the really technical stuff i might speculate something to do with boot loader.
Oh for anyone here who bricks, Don't freak... sometimes i do several times a day and have always come back from it ... mostly using the advice of all the brilliant people here, occassipnaly by messing around with adb, and once i let my monkey push random keys since he had already managed to compose a sonata...

boot loop issue

Hey guys,
Not exactly what to make of this which is why I'm posting. Here's the run down. Started off running Scamble_v01.3[CM6.1.3] for quite some time with everything just fine. About 2 weeks back, decided it was finally time to step it up to a Gingerbread ROM, and went with Wolfbreak's. For the first week, everything ran perfectly fine. This past week, I started to have issues with it rebooting every time I would run an app. Finally, this morning, it rebooted, and then just as it would get to the lock screen, it would say formatting SD card and then reboot. It would continue to do this repeatedly. I tried reinstalling in xRecovery (mind you I did Factory Reset (Full wipe), Wipe Cache Partition, & Wipe Dalvik Cache as well).
With high hopes, I restarted it. Unfortunately, this didn't change anything. I took my microSD card out and put Wolfbreak's updated ROM on it which just came out in hopes that maybe the file was corrupted somehow, just to find that when I tried to install it through xRecovery it, gave me an error that it couldn't because the SD card was busy. Stated in his ROM even, it says that you need to backup the ROM just for this very reason, however the only backup I had was of Scamble_v01.3[CM6.1.3] since I found it pointless to try and back up a messed up ROM.
Not knowing what else to try, and knowing that that was the last stable state my x10 was in, I restored that. Once again, it did nothing as far as the boot loop. I've gotten to the point where I have used FlashTool to flash the Generic Gingerbread ROM which just as all the others, gets to the first screen (which asks me to choose a language) and then reboots.
I'm completely stuck here and can't think of what I may be missing here. Any help would be greatly appreciated.

Maybe give flashtool a go, just flash one of the stock firmwares.
Already tried that. As stated before, it gets to the first screen which prompts me to chose a language, and then immediately reboots

[Q] AT&T splash screen loop

So, SGH-177 had been rooted and installed CM7, then Unnamed, then AOKP. All were pretty buggy. We wanted to bring it back to factory (with root if possible). Not for a warranty claim, just so it would be somewhat stable.
Anyway, I found a one click ODIN solution for UCKH7 stock. I used that, it passed. then the phone just looped through the AT&T "Rethink Possible" splash screen. I tried to get into recovery mode, but it wouldn't load, so I flashed the Siyah kernel to get CWM on there. Still I can only get into download mode and the phone loops the splash screen.
I hoped that it was just taking some time to load up the first time, so I left it overnight. Still stuck on the splash screen this morning.
I spent hours on here last night and found lots of people saying that if you have access to download mode, or recovery mode, you should be able to fix it. I wasn't able to find any answers as to how.
Help?!
I've had this same problem before. what always fixes it for me is to get into the factory 3e recovery to do a reset. I know you said you couldnt get there but make sure (while the phone is off; remove battery if you have to before this) you are holding down both Volume buttons and the power button at the same time until you see the "Samsung Galaxy SII" screen, then release the buttons.
factory reset, then it should be fine.
If you can't get to recovery, read some more on here. I'm sure something is out there, but I don't know what it is.
Here are two posts that might help you out. I've been doing the same research since my "Oh crap its stuck in a bootloop I'll sell it cheap on eBay" SGII is due to arrive today or tomorrow.

Best of luck to you!
UnNamed buggy?
Out of curiosity how did you root and flash, cause that is probably one of the most stable builds we have with minor changes to stock.
Anyways good luck getting back to stock.
So, for some reason, the next time I tried booting into recovery, it worked. I got a couple errors, but then it booted up just fine. Don't know why it wouldn't get into recovery before.
Everything seems to be working as it should so far.
I'm guessing this may be why some of the threads I had seen didn't really offer a solution. Sometimes it finally works if you just hold your head right.
Thanks all!
Regarding UnNamed... I don't recall the method I used to root, it's been a long time and I've done various work on this (my wife's phone) and my Nexus One. Easy to get it confused. I flashed it through CWM recovery, factory wipe, flash from SD.
It worked fine for a while (a couple months), then it got really glitchy. Unable to answer phone calls, random reboots, etc.

Did you also wipe cache and dalvik? May have been the problem...
I don't recall, but would be surprised if I hadn't done that
A year ago. When I first started flashing roms. I spent an entire week just reading the atrix forums and learning. I planned. I schemed. I asked questions. Through pm. And googled a LOT. Then when I had learned enough I did it. Point is....if yer not willing to have patience and learn as much as u can before u jump into this. Then its maybe not for you.

Interesting story regarding a Fascinate I bought off craigslist...

I bought a fascinate from good ol craiglist for a friend. When I bought it I noticed the original user had already rooted it and installed CM7.
Because I didnt know what he had done to it I decided to start from scratch and used Odin and flashed powerwashed_20_b3_Full_ec09modem and the atlas_v2.2.2.pit
After that I flashed cwm4_fixed_for_cm7-ODIN.tar and began getting ICS on this baby (teamhacksung-ota-eng.BUILD2.zip followed by build 11 at the time).
Everything was gravy and I gave the phone to my friend who was a happy panda. Several weeks later he calls and tells me the phone is stuck in recovery, I assume he borked something so I headed over thinking I will just Nandroid the ICS ROM that I set up before I gave it to him.
Funny thing was after rebooting from the Nandroid, the phone goes back to recovery! I was a little confused but assumed that maybe the Nandroid went bad when I backed it up. So I decided to just reflash build 11 again, after the flash was successful i reboot and.... back to recovery?
At this point I was pretty confused, CWM appeared to be working but it wasnt. Nothing was working, not even flashing CM7. The only way I got it to work again was to Odin the powerwashed_20_b3_Full_ec09modem and the atlas_v2.2.2.pit again. So that was what I did and got him back to ICS (build 13 this time).
Thinking it was a freak occurence I didnt pay it any mind, until he called me again several weeks later saying its stuck in CWM again!? So I check it out and sure enough it keeps booting to recovery and not able to nandroid or flash anything (even tho it says it does successfully).
At this point I assume its a hardware issue but dont understand what exactly, I bought another on craiglist and will swap with him and further investigate the issue.
I looked around the forums to see if anyone had a similar issue but have not seen anything like this. Anyone have any ideas??
This is most likely caused by doing the three finger reboot on the newer ICS roms. Tell them to pull the battery instead the next time their phone locks up. Also, there is boot loop breaker in the development section.

I assumed that as well, however my friend has no experience with these devices and would never hold down all three buttons for any reason. Both times he had reported that the phone randomly went into recovery on its own.
He could be BSing me of course, but I'll be testing it when I get it back tomorrow and see if I can recreate the scenario.
But I will be including the boot loop breaker file in the SD card and see if that at least makes this phone usable again instead of having to use ODIN every time. So thanks for that info!
Check kernel settings. Sleep Of Death, maybe?
