[Q] Droid stuck in boot loop - General Questions and Answers

Long story, but here goes...
About a week ago I turned off my Droid. When I attempted to turn it back on it got stuck at the Motorola logo screen. After a few minutes it would reboot and do the same over and over. I had never rooted or done anything custom to the phone at any point. It was 100% stock original. Nothing had changed recently to suddenly cause an issue, no new apps or anything. I spoke with Verizon about it and they walked me through the process of attempting to boot to the recovery screen. During this call we found that I could not even boot to the recovery screen. I am outside of the warranty and inside of my renewal date.
Since I don't intend to pay for a new one I decided to try to fix it myself. My first attempt was simply to get to a point that I could boot to recovery. I flashed the phone with SPRecovery and sure enough I was able to boot to recovery. I then attempted to flash it with 2.2 and ended up back in the same situation with the boot loop. During all of this I noted that the Bootloader version was 2C.7C.
I then decided to go back to the SPRecovery/rooted configuration and attempted to load a custom ROM from Liquid. This also failed.
My next train of thought was to flash back to an older version of the Droid OS. I chose to flash to VZW_A855_ESD56_QSC6085BP_C_01.3E.01P_SW_UPDATE_03. Low and behold, that worked and the phone booted up and ran fine. It immediately updated to 2.1 update 1. I noticed after this flash that I was on Bootloader version 2C.6C.
Shortly afterwards I was prompted to install the OTA 2.2 update. After accepting and installing I was back to having a bricked phone. This was through the OTA update. Nothing I did or forced.
So basically, I can flash the phone back to VZW_A855_ESD56_QSC6085BP_C_01.3E.01P_SW_UPDATE_03 again and it works fine. But the second it tries to install the 2.2 OTA update or if I attempt to flash to the 2.2 image it gets stuck in the loop.
Notes that may be important:
1. I get the "E:Can't open /cache/recovery/command" error when I am able to get into recovery.
2. I have been sure to wipe data, cache, etc and formatted the SD Card through the phone OS when possible.
3. I use Ubuntu to flash the phone as it seems more stable and easier for my preference (I like Linux commands )
Any help would be greatly appreciated!!

I'm also stock in a bootloop, lost count already...

Nexus One doesn't load past the multicoloured logo

Ok I have a massive problem here. Last night I decided to use the 1 click universal root app to root my phone and flash it to get CM.
I downloaded the app did the root, downloaded clockworkmod then did a clockworkmod recovery. After that finished i was given a pre-root option to backup my phone and wipe data/storage.
I only chose back up my phone. My nexus one then rebooted and proceeded to backup my phone then it went to install CM 6 RC2.. After this had finished it then rebooted and went to the multicoloured animation where the colours ceom from the left and right..
Here it would continuously loop and never do anythign else. With this I pulled the battery and loaded into recovery where I was in ClockworkMod. I then proceeded to use the recovery and as it was doing the recovery it just froze and the progress bar nor any words would come up.
From here I pulled the battery again did a soft/hard reset but it would hang on the loading animation again. I then did a wipe data/clean option and now it just hangs on the X logo.
On my sdcard I still have the clockworkmod folder with the backup, nandroid, system and all the other files as well. Vodafone Australia have no stock of the Nexus One at all and won't be getting anymore in since it's a finished product
I barely have any cash for a new phone and need to know asap what to do to fix this problem! If anyone can help!
When you installed Cyanogen CM6 did you install the proper baseband also or you just didn't write it down for us? If you had 2.2 on the phone before you rooted the baseband is ok for CM6.
Did you try hooking your phone with USB and try if ADB interface works? If your computer sees the phone via fastboot?
IF fastboot works, you could always restore your stock recovery and install a stock FRF91. (And then try again with CM6, this time installing the proper baseband AND WIPING like you should when installing CM6!!)
When installing custom ROMs always read the install instructions whole first then install.

Nexus S won't boot to OS

I have the Nexus S from Telus.
It was rooted, unlocked, running CM7. However I've been having issues with it freezing and decided I want to go back to the stock rom.
I ended up downloading what I thought was stock ROM for my phone (Stock GRH78 Nandroid Backup in this Tutorial http://forum.xda-developers.com/showthread.php?t=884093) however after it flashed my phone, I ended up with a phone which was essentially stuck in Airplane mode, would not connect to Telus. I'm guessing that it has the wrong radio for my phone/carrier?
So then I ended up finding a zip file someone posted Stock-GRJ22-i9020A-unsigned which should have worked, I ended up flashing the zip file from recovery.
It said it installed fine. Rebooted, and now the phone just cycles the Samsung Loading screen endlessly.
I tried to go back to recovery, and it gives me yellow triangle with !.
Is there any way to flash the recovery image back to the phone?
I plug the phone in and the PC won't recognize a device.
I installed the Android SDK
Ran the command adb devices, no devices attached to the PC.
I tried fastboot devices - blank
I don't know how I'll be able to get files back onto the phone SD Card for flashing etc...
I had the exact problem two days ago...flashed an image that jacked my phone up. Wouldn't boot past the google logo. Sat there indefinitely.
Read this thread and see if you can get it work. In a nutshell, you need the PDA net drivers installed. Since PDA net can't install the app on your phone (because it's not booted into an OS) leave the install program in limbo and voila, fast boot will work. From there, push the recovery.img (google Clockworkmod recovery image), boot into recovery and you are off to the races.
This is, of course, assuming you already have a ROM image on your internal SD card you can flash to get back up and running. I'm not sure how to install a .zip image ROM if you can't gain access to your SD card.

Good luck, I know the feeling. It blows.
Ah, just found out how to install a file on a phone that won't boot.
You do need to flash CWM recovery first though.

Good news! I tried a factory reset/data wipe and rebooted the phone.
It doesn't hang anymore, all functions restored and the phone is working on Telus again!
I guess I had to format data, clear cache, before the flash of the rom.
So relieved.
Issue has been solved!

Update process for OTA 3.1.1 on noOTA Shield?

Hi folks,
My NEW (RMA) Shield is rooted / TWRPed / 3.1 / and I applied the noOTA process to it so that they couldn't force-push some future undesirable OTA (or accidental bricking) at me.
Of course, as soon as I get settled in to the new unit with all apps and data where I want them, they do this new OTA.
What's the process for applying the latest OTA, given a rooted, TWRP recovery system? Do I just boot to TWRP, flash the full OTA, reflash noOTA, and be done? But wouldn't the full OTA kill TWRP, so I should reflash it?
Before I mess up this thing I want to make sure I get it right. I've got a PC so I can ADB/Fastboot sideload stuff if need. My main interest is in not messing up my data and apps.
Thanks
:highfive:

that's correct. this update in particular doesn't upgrade the recovery too, so TWRP won't be affected, but if you have an unlocked bootloader, you can just reflash TWRP at any time. for root, you might also want to flash SuperSU from TWRP (it will ask before rebooting if you don't install it yourself)
Thanks Bogdacutu.
I copied the full US LTE OTA 3.1.1 over to the internal memory (I used the downloads folder), rebooted to TWRP, and flashed it from TWRP. Before rebooting, to be safe I also flashed nomoreota.zip and then supersu.zip. On first boot I got the typical post-OTA "android is updating" thing where it optimizes the apps. Any idea what this app optimization is? I've always wondered... This app optimization process actually took longer than flashing the OTA and stuff.
After finishing the first boot, SuperSU told me it needed to update the binary, which failed. It suggested a reboot.
I rebooted normally (not going into recovery or anything first). This boot stayed on the NVIDIA boot up screen a lot longer than usual. after about 10 minutes like this I turned it off. After it was all the way off I turned it back on again. This time I let it go about 20 minutes. Still nothing past the NVIDIA boot screen. Crap.
I turned it all the way off. Rebooted with volume down button and was relieved to see it give the usual options (continue, recovery, fastboot, etc.). I let it go into recovery and got to TWRP in short order.
At this point I turned it off, as the battery was getting a bit low and I have to take my kid to a soccer game. I'm charging it in powered off mode until I get home.
Any ideas what to do next to get this thing booting into Android again?
Thanks
Marc
After it charged all the way up, when I got back from my kid's game, I booted back to TWRP and reflashed the OTA update.
I then told TWRP to reboot... it said something about should it reflash SuperSU script to preserve root. I agreed and let it reboot. It came back up in Android. I'll explore the situation and report back.
All seems well at this time.
According to rootcheck my root is preserved. SuperSU successfully updated binaries in normal (non-twrp) mode. Checked for system update. It said I was up to date. I booted back to TWRP, flashed nomoreOTA.zip again. Rebooted again, no problems. Back to normal, fully updated. Phew.
I'm not sure what went wrong the first time, but it seems OK now.

Bricked Shield (wifi) tablet after flashing 6.0 update

Last night, I downloaded the 6.0 update, copied the .zip to external storage, rebooted to CWM, and flashed it (successfully), then flashed SuperSU over it, cleared dalvik, and rebooted.
Since then, I'm stuck with the Nvidia boot screen. I can use Power/Vol Up to get in to fastboot, but when I try to boot back into recovery, the screen goes black, but goes back to the Nvidia boot screen instead of booting to recovery, even after flashing a recovery image to it via fastboot.
I can probably fix this with enough time and tinkering, but I just came back from a two week from vacation at work and don't have the time to futz around with this. Posting here in case someone already has an idea on what the problem is/how to fix this.
Update: I was able to get back into recovery using TWRP referenced in http://forum.xda-developers.com/shield-tablet/general/unofficial-update-original-shield-t3281541. Direct link is https://www.androidfilehost.com/?fid=24345424848487676.
I'm thinking this is a kernel issue.
This was a kernel issue. Flashing a older OTA (http://ota.nvidia.com/ota/data/post...wf-full_ota-36442_589.1541.20150826095201.zip) and booting normally, then rebooting to bootloader and fastbooting the CWM image worked. I'm restoring from a backup I took before flashing the update last night, then flashing TWRP, backing up, and trying this all over again.
Thank you, I was having the same issue :good:
Have the exact same issue, except that now, for some reason, I can't even get the device to turn on!

K1 - So I think I may have bricked this thing. Looking for help, if any.

Well, not fully bricked, but it's completely non-working just the same.
I've had the K1 for a few years now and have been fine with the standard, stock OTA updates. Recently though I've been seeing constant notifications that I'm short on ram and after uninstalling apps, deleting old files, it would work ok for a few days and then start complaining about low memory again. So I figured that something must be corrupt and now is a good a time as any to root and see about flashing a new rom.
I've owned many android devices over the years and have rooted and patched most of them. so I'm familiar with the tools.
This time however, I think I must have crossed something up somewhere.
What I did was this:
Grabbed the minimal ADB package and fastboot drivers.
Booted into the bootloader and ran the fastboot oem unlock. No problem.
From the nVidia site, I then grabbed and flashed the latest stock image and recovery, just to ensure I was on a clean slate. No problem.
Flashed the latest TWRP for the device. No problem.
Flashed SuperSU. No problem.
Booted into the stock system to make sure everything was still working and it was. But, this is the start of where I maybe hosed things up(?).
While running stock, I converted the SD card to internal memory, just so I wasn't having to mess with it later, not thinking that I'd have to do it again anyway after flashing a new rom.
Rebooted back to TWRP and proceeded to flash the new rom (AOSP Extended (AEX) 5.8).
I flashed it by way of the sideload method rather than from a zip file sitting on the SD card. This all seemed to work just fine.
Next I went ahead and flashed OpenGapps Mini. This resulted in an error 70 and after reading about it, it was a simple matter of going into the advanced settings in TWRP and extending the system partition. Did that and OpenGapps then flashed with no problem.
Finally I wrapped it up by flashing tegra124-tn8-p1761-1270-a04-e-battery.dtb and rebooted.
... Nothing. Now I know that when flashing a new rom, the first boot can take some time, but I let it sit for about 2 hours with no result. It didn't appear to be boot looping, but instead just stuck on the nVidia boot screen. Forced it to boot back to the bootloader and brought up TWRP. I obviously did something wrong, so I prepared to reflash the stock image.
Did the wipe, flashed the files and rebooted. Again, nothing.
This time however, not only can I not boot to the system, I now also can't get back into recovery.
No matter how many times I reboot, or attempt to reflash anything, it hangs on the boot screen when attempting to get back into recovery.
So I'm stuck. I've tried reflashing TWRP, stock recovery and stock system, with the SD card in and out, a number of times, all with no joy.
I can access the bootloader, so I can at least run fastboot commands, but that's all I can do. Without being in recovery, I can't access an ADB shell if I need to repair anything.
If you're still with me after this rambling mess, do I have any hope at all in recovering this thing?
Hi,
I think the problem is in the modified .dtb try flash the original file.

That got me in the right direction and I can at least get back into recovery now. Thanks! :good:

I'm also sort of in the same boat i had a custom rom installed and decided to go back to stock os and now i'm stuck at either the Nvidia Logo or the Fastboot menu there's nothing else it let's me do i'd take any advice at this point. I can use Fastboot commands and I've tried Flashing Twrp.img and also flashing all the stock os which goes through with no problems i reboot the device and it's just stuck at the Nvidia logo
Ps: how did you manage to get back into recovery
Hello.
I think i had the same Problem.
I Flashed a Custom Rom, MiniGapps and the tegra...Battery file and since then i had boot loop an the NVidia Logo.
The Problem was: i flashed the tegra-Battery.ZIP file!!!
I noticed that i have to unzip it and flash teh tegra-..battery.DTP file.
since then it booted up again.
the OpenGappMini was buggy. it worked with the Nano!
Hope this helps for you as well!
OMG you guys. I did the exact same damn thing. Flashed the ZIP instead of the DTP file. 100 million thanks to you. I'm going to give it a shot now.
It worked! I wonder how many other folks didn't realize it wasn't a zip to flash to dtb and bricked their devices.
