[Q] Bootloop comes out of nowhere - AT&T Samsung Galaxy S II SGH-I777

Had ICScrewed running for 4+ months and out of nowhere phone won't boot and is stuck in samsung bootloop.
I have searched and can't seem to get any solutions to work. I have done so much crap I am thoroughly confused as to what I have done and what I haven't tried yet.
Someone please send me in the right direction.
Right now last thing I flashed was "I777UCKH7 OCD Root No BL" oneclick.
Any ideas? I appreciate your help!!

Something changed to trigger the bootloop. If you can pinpoint some event that occured just before it, that might help determine a solution.
From what you say, you must now have stock UCKH7 installed. If you can boot into 3e recovery mode, try a wipe data/factory reset, and clearing anything that it will let you clear. Don't remember the stock recovery very well.
Or, if the bootloop will let you get into 3e recovery, you could flash a custom kernel back onto the phone, enter recovery and clear cache and dalvik cache, etc. Also, if you have a nandroid backup, from custom recovery you can restore the backup to get your phone to boot again.
If you need specialized files to flash to recover the phone, you will find them in the Download Repository, linked in my signature.

I didn't do anything I can think of that would trigger this. I can't get into 3e Recovery it says "Deleting Cryption Meta Data" and just reboots.
I flashed via odin "SGH-I777_ClockworkMod-Recovery_5.0.2.3.tar" That gets me into CWM Recovery... i wiped data/factory reset... cleared cache... doesn't help.
Then I tried SD card to load a custom ROM and everything on the external SD card is completely not what shows up when i have it in my computer.
I am so lost.

I just got a custom rom onto /sd with Droid Explorer and renamed it update and it installed but is still stuck in bootloop.
Any ideas? I need my phone for my business I am soo screwed!

Flashed SiyahKernel v2.6.14 and with stock rom it works. Thanks!

Be sure to make a nandroid backup once you have it configured the way you want. Restoring a nandroid backup is the first thing I would try if that type of problem ever happens again.

[Q] Need help - Can't get past recovery.

Hi guys.
I got a problem.
Got tired of lags, so i decided to wipe (data + dalvik) and reinstall Omega 27.1.
Now i can't boot up the phone - it just starts up CWM (6.0.1.2) when i reboot. Have tried to pull battery and when i insert it recovery just comes up.
What have i missed?
I have tried to install again, with and without wipes but still the same.
Can't restore nandroid either. Getting error on restoring /data, and just comes back to CWM again.
I'm kinda stuck.. ideas?
EDIT:
Just did a nandroid restore, error on restoring /data as always, but i rebooted and got into Android. I had to type in my google account information again, and all apps crashes all the time.
So I rebooted to recovery, and installed 27.1 (did a full wipe again), and now i can't get past recovery again.
Wtf?

If you can get into download mode, flash a stock rom samsung www.sammobile.com with ODIN, then get root permissions and cwm with ]cf-root 6.4

Yes, it seems to be the only thing to do..
But does anyone know what is causing this?
Can't be the boot.img, because restoring the boot (wipes+restores) doesn't work. And installing a new rom also adds a new boot.img.

[Q] SCH-i905 - Can't Factory Reset & Can't Flash

Hi Guys
I am new to playing around with android but not to electronics. I have a Verizon Samsung Galaxy Tab 10.1 16gb (SCH-i905) with current 4g service.
Here is the problem I am having:
It started yesterday, I was browsing the web and the tablet froze and then rebooted. After the reboot programs randomly freeze and crash, if I reboot anything I have downloaded is gone and anything I deleted is back and I can't install or remove apps. I figured I had something corrupted and a factory wipe would fix it. Unfortunately when I perform a factory wipe from the menus or through Android recovery nothing happens. The tablet boots up like nothing was erased. Still has all my accounts, security pin, apps, and so on.
So after that I figured I would flash the tablet, I found the thread here in the development forum with the stock 3.2 image to load through ODIN. I downloaded everything, followed the instructions. ODIN says the flash was successful but when the tablet reboots it still has all my info and is running 4.0.4. I have tried this multiple times. I have tried loading CWM with ODIN but it will not stick.
Any thoughts? If you need more information I will get it, I am just stuck and can't find anything that helps me with this problem!
Thanks for your help!!!
If you want cwm to load after you install it using odin, then you must immediately boot the tablet into recovery without letting it run normally. During the normal boot process, CWM is deleted and the stock recovery is restored. Therefore once Odin finishes installing CWM, hold the volume up button and once you get to the recovery mode you will be running CWM instead of the stock recovery module.
Regards,
Michael
Yes, I did read that in the multiple thread about installing CWM and have gone into recovery directly after ODIN reboots the tablet, however it is still only the stock recovery app.
Any ideas why the factory reset / data wipe won't work?
So after several more hours working on this problem I think I have come across the root cause. I believe that my internal storage has corrupted and is now only mounting in Read-Only mode. From everything I can find online, without having root access previously, this is a no go for fix it yourself.
In case anybody happens on this post down the road, I have been unable to find a resolution and it would appear I must sent the unit back to Samsung for repair.

factory reset through the stock recovery should be able to get you out of it (RO filesystem).

I guess that blows my theory out of the water. I can't make heads or tails with this. No matter what I do, Menu Factory Reset, Recovery Wipe/Reset, ODIN Flash Stock EG01 firmware, ODIN flash CWM Recovery as soon as this device reboots I am right back where I started....... GAH!!!
Thanks for letting me know I'm probably wrong.

it has to be factory reset through the stock recovery (it will format /data), not through CWM.

Yup, done that multiple times. I'll take video of it if you want, Factory Reset in stock recovery has no effect.

odin flash CWM (you can use 6.0.2.8 in JB CM10 folder on droidbasement), boot it and try to format the /system partition first then /data.

HI Pershoot!
I forgot to say thanks for your help!! I appreciate someone smarter than me lending a hand.
That said, I just tried to flash CWM from DB Galaxy Roms/CM10 folder. Upon reboot the tablet still entered stock recovery, I have tried this several times, but this time I took a video. If you feel so inclined to watch it maybe you can catch me doing something wrong....
Again thanks for your help!!

I had to do this on mine. http://techne.alaya.net/?p=8829. I rooted and modified the file described in the steps. Weirdly enough it still booted into stock recovery the first time I installed CWM. I installed CWM one more time and the tablet now boots into CWM.

Bootloop Help? IM DESPERATE

I installed a bunch of root apps that ended up putting my phone into a bootloop. I had superuser on it with Titanium backup, and I was able to undo the loop. I am now just stuck on the screen with the triangle after attempting to put a stock ROM on the phone. Its an Epic 4G touch, Im able to get into Recovery and Odin mode. Ive wiped all partitions, dalvik cache, etc. Still stuck. How can I get back into my phone?

Did you install twrp or cwm? Sounds like you wiped the system off and need to install a rom now thru recovery after you put it on your sd card. Dont wipe your sd card. Fallow the steps to install a rom.
i had also face same problem
the i had flashed costom rom and kernal
and also my old backup then also
there is no result
only the in bootloop and open only cwm recovery only
then i had flash custom recovery
it works and my files and app are safe.

Bootloop (Device Always Boots Into CWM)

Hi everyone, I have a problem with my phone.
It is no longer booting into the OS, instead it boots into the recovery mode.
So here's what happened. I was on Google Play Store looking for some utility apps, and found this "[ROOT] Rashr" app, read its details and got interested in it since I also do wanna try to back up my CWM Recovery. I don't even completely understand what it means, but as what the apps says, I really thought that with it, backing up my recovery will be very easy, just like how ROM is backed up when you do a NANDroid backup. So, after it was installed, I head on to its Back-Up section, ticked the box for "Recovery", and tapped on "Go", expecting that it would work. It said "Rebooting..." and booted to recovery mode, so I thought that I had to complete the "Recovery Back-Up" inside CWM, so I spent time looking through the options. And, this is where I discovered that CWM has a rainbow color mode. When I found out that no signs of back up could be done in CWM, I rebooted from within CWM. BUT, it still booted to Recovery Mode.
I tried . . .
Odin, but since it boots only to recovery, Odin isn't detecting it.
Wiped the data, cache partition, and Dalvik cache. Then restore.
Can this be fixed? I badly need help.
I have:
CWM Recovery v6.0.3.6 (used when I rooted the phone), updated to v6.0.4.5 (current)
Stock ROM 4.1.2
Recent NANDroid Backup
Any inputs will be very much appreciated. Thanks.
No intention of giving the "Rashr" app a bad name. I just didn't know how to use it.

I never thought the solution would be that simple. Hehe Thanks manoj. :good:
Finally fixed it!
What I did:
1) Flashed the stock Recovery. I was surprised it was able to boot to Android cause I was thinking that the zip is only the stock recovery. It had errors though. Home Screen won't appear or load.
2) When rebooted, it got stuck in SAMSUNG boot animation, but it was all good cause Odin was still able to detect it which means it can still be rooted. So . . .
3) Flashed CWM Recovery v6.0.3.6
3) Wiped data, cache partition, and Dalvik cache.
4) Restored the backup.

Bricked Samung Tab E Verizon

Hi all,
Sigh. So it looks like I bricked my Samsung Tab E Verizon. I rooted it with King root and when I removed it, it is now in a endless boot loop. I've tried all sorts of things to try and recover it.
I used SkipSoft to set it up to be flashed but odin fails everytime. I was using the new ROMS found on this Forum. I've tried putting it into download mode and manually flash it and that didn't work. I can't Re-Root it as it won't stay on long enough to Root and they always fail. Right now I'm at a loss.
Can anyone help?
Thanks.
Do you have custom recovery or default? if you have default you can hold the home button and vol up button then the power button to get into recovery, once your done with that you can wipe cache and reboot, if that STILL does not work then factory reset your phone and re wipe cache, i know losing data sucks but its better then a brick. (this will work 99% of the time because the default recovery automatically re-installs stock rom)
If you have a custom recovery, then i recommend wiping everything including dalvik cache etc, making sure EVERYTHING is squeakly clean (execpt recovery obviously) , and find the driver for your samsung phone and download it on your computer and install, once you are done with that, put your phone into download mode, find your original STOCK rom for your phone, download it and flash it with odin, from there IF successfull you should have a fresh boot of your stock rom, then you can re-root and go on with your day.
Also make sure once you re-gain root access backup your rom so you will always have a plan b if everything goes bad. i cannot recommend this enough, even if you are an expert with flashing, there is always that small percentage things will go wrong and you should always have that backup ready.
Hi!
Thank you very much for the reply. You know, that was one of the things i tried initially when it happened. When I tried it, it wouldn't go into recovery mode. I then went on the odyssey of hell in trying to recover it.
When I read your post I was thinking; "Yeah I tried that", but then I thought I would give it another shot. I went into Factory Reset, it then actually went into the recovery menu. I deleted the cache and set it to data/factory reset and it's still looping. I get an error saying; "E:failed to mount /preload (no such directory)". I then tried to run update from external storage and it's telling me that it's disabled. I tried to update from ADB and it's disabled. I tried to apply from cache and it says; "APPLY_CACHE is depreciated". It's still looping.
Urghhhhhhhhh.......
