[Q] [Help] Bootloop on Stock-rooted - Samsung Galaxy Nexus

So today, While I was using it my phone suddently rebooted. Since then it could not boot back to android and is stuck at the google logo. I can still access CWM but even data wipe did'nt do any good.
Is there any way to save my phone ?

Yes, definitely. If you're able to access download mode or the custom recovery, the device is easily recoverable. By easily, I mean most users are able to complete the steps although some users require more time and labor than others.
When the device hangs at the initial boot logo screen, in your case the Google logo, this generally indicates an issue with either the kernel or the ramdisk. The simpliest solution is generally to flash a known good kernel which is compatible with the currently loaded ROM.
If you have a nandroid on hand of a previously known good working state, that would be the easiest to restore. If not, you'll want to find a known good working kernel which is compatiable with the currently loaded ROM. If you're unable to find this combination, a ROM and compatible kernel will need to be loaded.
The odd part of the situation is how it seemed to "randomly" reboot and encounter this issue. Without knowning the details of the custom software loaded, difficult to accurately speculate the root cause.
Hope that helps point in the right direction!

Thank you.
Since I didn't know how to push files from my computer to my phone and had already done a full wipe I flashed google factory image and it worked!!
Now evrithing is good.
Thank you one more time, it realymade me freak out...

you wont't brick your phone unless you somehow brick the bootloader, even then you might be able to recover

Galaxy Neuxs Encryption woes!!!

Hey All,
New to XDA but been using this site years so my level of Android knowledge is not bad.
I am currently having a huge problem with my Nexus. I used Google Apps encryption on it recently and that seems to have bricked my phone. I am unable to reset to factory settings to wipe the encryption as recommended by Google and I am stuck now with a bricked Nexus.
I also tried flashing stock roms with Odin which appears to work but the encryption still remains. All I am trying to do is put the stock back on my phone and re-root but I am having no joy. When using CWM to flash a new rom the system does not mount in recovery mode so I can't load any other roms. I have also tried the fastboot method but it stalls on waiting for device all the time.
If anyone has seen this and can help or if anyone just knows how to fix it please help me! I am stuck now with a useless Nexus. I should have just left it alone but as usual I couldn't.
Any help would be so appreciated. Thank you.
By some chance is your phone both rooted with CWM?
Hey, yeah it was so when I did a factory reset it could'nt use the stock bootloader so it didn't know how to wipe it. Unfortunetly once you apply encryption from a Google Apps the only way to remove is to factory reset.
I got around it by fastbooting the stock bootloader, radio and image from Google. Then I completed a manual reset using the original bootloader.
A world of hurt really! I have learned a lot but never going near Google Apps encryption again. It also slowed down the phone too.
Anyhow all sorted now, re rooted and running revolution rom now.
theres another thread with a guy who had the same problem. I wonder if vzw nexus has an issue with encrypting...
If the phone wasn't rooted I would have had no issues. It is simply a problem when it comes to loading roms. In CWM the recovery cant mount the data/system so you can't flash anything. Also doing a factory reset from settings doesnt work because the phone is looking for a stock bootloader which it doesn't have once you root. So I ended up in a loop and could do nothing. Fortunetly I learned all about adb and fastboot this morning, never heard of them before and that allowed me to reload stock and unroot. I still had to wipe the phone using the bootloader as I couldn't get into the phone or past the encryption.
If anyone is having issues with this I will gladly help as I really thought that my phone was bricked and was very frustrated. The only way I got help was from a guy on this tread http://forum.xda-developers.com/showthread.php?t=1392037&page=3

[Q] Stuck with no OS, no emmc access Epic 4g Touch

Hi all,
I'm new to trying to root the E4GT and I've gotten in a bit of a jam. I don't think I'm completely borked because I can still easily get the phone into download mode or Clockwork recovery, but I'm stuck on what to do next and I want to proceed carefully so I don't accidentally turn this into a hard brick.
Because I'm on Linux, not Windows, after reading up on rooting the E4GT I installed heimdall. It's not the most intuitive program in the world but I eventually worked out rooting it using "heimdall flash --kernel ~/path/to/zImage" where the "zImage" in question belonged to Zedomax v3 as linked from epic4gtouchroot.com. That seemed to work brilliantly as I was able to boot into what appeared to be a reset phone, now with a generic Android boot animation rather than the default Sprint advert, and I had the Superuser app.
From there, I decided to try Strongsteve's Odex blue and I booted into Clockwork. Without even thinking about it I wiped the factory data and cache partition, and then started looking into what I needed to do, only to learn that my external SD was going to be inaccessible from here so I had the .zip file in the wrong place. I proceeded to reboot my phone to set things right but I was shocked when the phone simply appeared to turn off after the (new, rooted) boot animation played. The phone then becomes unresponsive until the battery is pulled, at which point it becomes responsive again.
Because it boots the Samsung logo (with the yellow warning triangle) and part of the boot animation, I have plenty of time to get it into download mode or Clockwork, but I don't know what my next move is. I guess (based on a bad experience with trying to root a Kindle Fire) that this is still recoverable, though. Should I just flash a stock/stock rooted ROM? Reflashing the Zedomax kernel doesn't seem to work like it did before. Has anyone encountered this? Does anyone have a link to a recovery method that should be reliable in this situation? Thanks in advance and please remember LINUX -- i.e., no Odin.
[[ PS - I pretty much described the whole process above, but in case anyone was wondering, let me explicitly state I do not have a working nandroid backup. I only got Clockwork after rooting successfully, and I didn't think wipe data/cache was potentially a brick! :\ ]]
UPDATE: Solved! I was able to successfully flash the zImage from the stock rooted kernel here. Phone is working (and rooted) once again!

[Q] Stuck in Bootloop

Hello,
I was recently attempting to flash the new Cyanogenmod 10 ROM to my phone and I've found myself in a bootloop (the logo just continuously circles). I actually know what error I made to cause this, but the problem is, I have no access to any recovery menus anymore. All I can access is download mode. I can still use Odin and connect to the phone, but other than that I'm at a loss for what to do. I have backups of everything, I just need to get the phone wiped and back to factory set and start over. Unfortunately, without a recovery menu I don't know what to do.
What should I do from here?
Solved it.
For anyone that has this issue in the future, I plugged into the computer and ran Odin and was able to have it install a stock ICS ROM and I just started over.
Good job with solving the issue on your own! :good:
Your issue and solution had been discussed on these forums already. As a tip for the next time you have an issue, make sure to use the search bar first. Cheers!

[Q] AT&T Galaxy SIII (SGH-I747) will not boot past Samsung logo

I have been using the i747z ROMs for quite some time and after trying a bunch of other ROMs I always reverted back to theirs. So when their 3.0 version came out with Android 4.3 I installed it, using ClockWorkMod recovery. Right after it installed, CWM displayed a message about the boot loader and to fix it. So I went ahead and did that (Don't really remember what the message was) What I know is that I lost root. Also the phone could not connect to the mobile network, only on Wifi. So this morning, I factory reset the phone again, and attempted to root the phone with Odin with CF-Auto-Root-d2att-d2uc-samsungsghi747 (which I had used when I first rooted the phone). Now the phone doesn't boot past the 2nd samsung logo, it starts out with the Samsung logo with the blue circle around it, then the AT&T Rethink Possible and then the plain white Samsung logo. Also, the LED has a slow blue flicker.
I can get the phone into download mode and I have used Odin to attempt to load the stock firmware and the stock bootloader. But after restarting the phone I can't get past the same screen described above.
I am pretty sure this is not related to the i747z v3.0 ROM but rather something a miss with the order in which things need to start in Android. I have done some reading on that but I am not sure what I need to do to correct this soft brick situation. ( I have googled "soft brick" as well)
Any thoughts would be greatly appreciated!

After flashing through odin did you format data?If not try it.
Go into recovery and wipe data.
**SOLVED**
Thanks xXFl4sh, I had tried that.
Solved!
Alright where do I start? How about RTFM Some how I had missed the part about flashing a bootloader and a modem after the ROM. Not recalling having to do that before, I skipped right over it. Once the recovery CWM 6.0.3.1 was finally loaded, getting the flashing the ROM, the bootloader and the modem was easy as usual.
The key was having to use Odin to install a recovery in .tar or .tar.md5 format since I could not access a Recovery Mode on the GS3, as well as a rooted stock image (I used root66_ATT_I747UCDLK3.tar.md5 which is a rooted Android 4.1.1 for AT&T) For the recovery, I couldnt' find a .tar or .tar.md5 for ClockWorkMod (did find a utility to convert it, but didn't want to introduce another variable into the mix) so I used one from Team Win Recovery (v2.6.3.0) and with that I loaded the CWM recovery. Once all of that was in place, I proceed to factory reset, clear data, cache, system and then flash the new ROM, bootloader and modem.
In all of this I learned quite a bit about the whole process and how to narrow down possible resolutions. I still see the "Rom may flash stock recovery on boot" message after flashing either a ROM, bootloader or modem, but just backing out without answering Yes or No seems to work. Also (and this may be related, I don't see the option to restart in recovery from shutdown menu). Don't really know what that's all about for now, and honestly don't want to mess around (at least for a while)
I know the steps are general, but I hope this can help some else if they get their devices in a soft brick situation. As for the i747z v3 ROM with 4.3, I really like it, everything works (Wifi,Blutooth,tethering) and the battery seems good as well.
Thanks!

Stuck in Boot loop after weeks of normal usage

Hi.
I have a problem with my D855. My phone is rooted and runs the fulmics ROM. Everything was working fine, , on Fulmics 5.3, except than one day, I was using my phone normally and then it crashed. I saw the phone rebooting, but for some reason it got stuck. The phone tried to boot unsuccessfully until the "firmware update" went through, after what it reboots again (unsuccessfully) and so on.
At that time, I was able to access twrp, do some backup, and flash properly with a downgraded version of fulmics (from 5.3 to 4.1).
It was able to boot again and use my phone like before. Yet, after one month of usage, the same problem happened on version 4.1. The phone crashed and now cannot boot.
Any idea of where it is coming from? Should I go back to stock? Should I contact customer service?
What did you do before the phone crashes ?
I think you probably should flash the stock ROM and wait for an other crash... or not.

I haven't done anything special. I think that the first time I was playing on candy crush. The second time I was just looking at pictures in my gallery.
I was using the ROM without any tweaks or extra modules such as Xposed. Just regular use.
Update on my situation: I switched back to stock ROM and it seems to work OK for now (it has been 4 days). So I will wait and see if new problems happen. By the way, it was extremely difficult for me to get back to Stock directly from fulmics ROM. I tried several methods that I have found on xda based on LGUP or LG Flash tool without success. For some reason I was not able to connect the phone to my PC in download mode.
The only way that I found was to use a nandroid backup that I did just after rooting the phone and that was based on stock ROM.

You can also use the Stock rom flashable from twrp. So you can wipe the system partition and get a "better situation" than a nandroid backup that should be with an old version.
Or use this that has also root and other improvements.

Same problem here. Normal usage suddenly started to reboot and now it's stuck in boot loop
Coming from Fulmics too - stopped working one fine day.
Now, continues to boot-loop at the initial LG screen. Trying to get into the recovery shows me the the 'Factory Reset' screen, but beyond that leads to boot-loops again. Even the Download mode loops!
I'm at my wits end without a solution in sight.

Thank you for this advice. I was able to update my stock ROM after the Nandroid backup through LGUP, but your method would have been faster.
But anyway, I am waiting to see if I am stuck with bootloops again, using non-root stock version, so I can send it to customer service if this happen again.

Are you using Fulmics ROM as well? Can you have access to TWRP? I was able to connect to a PC in the recovery mode and to transfer files before flashing, in case you need some basic backup...

Silly question, but are you sure that you selected "Yes" when the screen asks you about factory reset? you have to press "volume down" and the "power button", since the default answer is no.

Yes, of course I was able to access TWRP successfully earlier.
Curiously enough, the phone boot-loops in regular startup, Download mode and trying to get to recovery. However, it doesn't restart itself and fall into a loop, while on the Factory Reset menu. Am I correct in assuming that the battery could not be the root cause of the overall problem? Because if it was, it would likely loop even on this Factory Reset menu as well as far as I understand.
Unfortunately, the phone restarts as soon as it lands in the Download mode so I cannot even restore to stock.
EDIT: Okay, weirdly enough it just booted and reached the homescreen before restarting again. What I did was let it charge to a 100% and tried booting while plugged in. Could it be the battery after all? Though this exact set of steps hasn't been helpful before.
