[Q] Bootloop! Help! - Android Q&A, Help & Troubleshooting

Hello all. Long time lurker, first time poster here with a rooting question/situation. I rooted a Verizon Galaxy Nexus, running Android 4.2.2 today. After rooting, I thought to give Cyanogenmod a try and see how I liked it. It worked great, other than that I couldn't get on my Verizon mobile data, despite setting the APN's correctly (or so I thought...) After messing with that for a while, I decided to go back to Android Jelly Bean. I didn't backup the previous Android, because the phone was freshly wiped and had a factory reset done. After downloading a stock Android ROM.zip, I installed it and went back to Android flawlessly. The version didn't come with SuperSU or Busybox, or Titanium Backup (programs I am customary to using with root access, like many others) I went into Titanium Backup like an idiot and started slashing programs, including another Superuser that had been included in the Android ROM flash that I wasn't aware of. After this, I went into SuperSU and it said I would have to boot the phone in recovery mode to get it to work, so I did. I have CWM custom recovery on this phone. After doing that, the phone started booting normally instead of recovery mode, then showed the CWM custom recovery icon, and continued this process for a while. "bootloop". I went to start the phone normally, and the exact same thing happened. Tried custom recovery again, and same thing. Google icon starts, then the CWD logo comes up and continues in this pattern. I can access the boot loader, but can't start the phone or access recovery. To top it off, I never turned USB Debugging on the phone. Any Ideas?

[Q]Cyanogenmod 10, stuck on boot screen (dual core)

I recently installed the Cyanogenmod 10 ROM to my Droid x2. It was done correctly, and was working fine for about a week. But, it is currently stuck on the boot screen whenever I try starting it up. This is what I think happened: After a while, I realized that I had never installed Bootstrap recovery, over CM10. I checked on the Official ROM page, and saw that the bootstrap recovery for CM7 worked on CM10. I had to leave, and didn't have time to install it.
Later that day though, While looking through my SD card contents, I realized I had a Bootstrap apk on it. Without thinking, I went ahead and installed it (I believe the problem is that it was Bootstrap for 2.3.4, the one I first used to install CM7, on the way to CM10) I brought up the app, and installed recovery. I did not automatically restart my phone after, and carried on. Later on, while texting, the phone crashed without warning, and tried to restart. It failed to start up, leaving me where I am currently.
I've tried rebooting with the phone unplugged, with the phone plugged into a wall charger, and with the phone connected to the computer.
Also, Standard Android recovery fails to start. It gets stuck on "Starting RSD protocol support".
My question is... Does anyone know how I could regain access to my phone? I did NANDroid backup, but, I have no way of accessing and installing the backups, while locked out of my phone.
If you can't access stock recovery then you'll need to SBF... once back on 2.3.4 you can root, isntall BSR and then restore the backup you created.
Yes, I agree. You can sbf, root, install normal bootstrap, and restore nandroid. Then you can install the cm7 bootstrap. I've used it with cm10 a2 and can confirm it does work with it. I didn't like cm10 so I went into the cm7 bootstrap and restored my cm7 nandroid backup. Shouldn't be too hard for you to restore your phone. Good luck.

[Q] Every Reboot is a Hard Reset

Hi,
I have an lg c800 -- mytouch q by lg
I rooted it yesterday and removed all the bloat. I also installed several root only apps to optimize the phone.
It ran smoother than even right out of the box.
So, I figured it be a good idea to backup the rom, and maybe later try cyanogenmod... So I installed Rom Manager by clockworkmod
It said i needed to install clockwork recovery rom. I went in there but it said my device was unsupported (only like 12 were) so I backed out,
and stupidly hit TWRP listed under "Recovery Already Installed". (thinking that meant what options I had to SETUP a recovery/backup)
I hit backup rom. almost instantly the phone restarted. After the bios, but before android it went to a screen with a box, and an arrow pointing from the inside of the box to the little android man. Then went to the regular android boot screen.
It does this every reboot now. The SuperSU is still there, whenever Rom Manager (which I have to reinstall each reboot) asks for root access I get that dialog box, so it hasn't actually hard reset the phone I don't think. But all the user data, contacts, apps, wifi passwords, google id "(to access Play) get wiped out.
I understand what I did wrong. I think I understand what its doing (booting to the factory rom as it was, and I can't set it to stop doing it each reboot)
What I need help with is getting back, if possible, to what I had previously, among other things, I had a bunch of tasker profiles and notes that will be time consuming to replace.
Thank you for your help.
EDIT: SuperSU is now listed among the factory installed apps. This is unchanged each reboot.
Question: If I unroot the phone what that invalidate Rom Managers ability to run before android boots?

OK so its not in the guide, but one is to exit the shell BEFORE keying adb devices. it does show.
but sadly I don't think this gets me closer to fixing what is broken.
Can anybody at least tell me if my stuff is still there or gone?
I have the impression that the boot loader is grabbing the stock rom and just expanding it and running it each boot, but that the old functional rom is still there but being unused --- like a dual boot type thing.
Am I off in left field here or?

more info: the bloat from the original rom is still gone, and SuperSU is intact and functional
Chui says its some flag in CWM that isn't getting cleared when the device boots.
I'm just trying to get the data my apps help at this point.
cmon phone nerds i still need some help!
no help.
The original ROM of your phone got modified after you rooted, hence no bloat and SuperSU intact even after many wipes.
I suggest re installing the factory ROM again, including the bootloader, radio and other stuff. That ought to fix the issue.
What phone do you have ?
So when it was modifying the rom that was running at the time, also the recovery rom was modified?
how do you reinstall factory rom if the phone never enters fastboot?
I'm all about wiping the bootloader (so it STOPS running recovery) but I have only made a little progress in finding how to do that without fastboot.
What I can do is run a root viewing file manager. I even found the log for the recovery it keeps running. But not what to kill so that it STOPS recovering.
Phone is LG C800DG
The LG rom update software has a recovery option but that didn't work.
One youtube video

Says I can get around this by using a flash utility the installs as an apk. I doubt I'll find one compatible with this phone though as support is very limited.
looks like everything out there says I need a 3rd party recovery already flashed...so that I can flash a stock rom.
sounds like the damn chicken and egg to me, to get stock fixed you need 3rd party but since you have stock you cant get 3rd party
It seems to be a general problem with your set as many others too have posted the same issue.
For stock ROM this should work.

[Q] Can't access recovery

Okay. So. After some trouble with houstonn's latest rom's lately (getting stuck on boot), I decided I'd give one more try for the 4/30 release. Clean wipe, flashed it, flashed minimal apps. Stuck on boot. WOOP WHO CARES?
This time was different - I couldn't access recovery. So I tried like 30 more times to access recovery. Couldn't do it. LGNPST back to the ICS stock bin (11c). Get my OTA update to 4.1.2, rooted with this method http://forum.xda-developers.com/showthread.php?t=2006946. After that, I tried to access recovery mode again. Couldn't do it. So, I was like "what the hell, maybe FreeGee will help." So I continued on to unlock the bootloader with FreeGee and with CWM. Installed quickboot and chose to restart to recovery. SAME THING. Black Screen after LG logo. Can't get into recovery.
Now I'm LGNPSTing back to stock to repeat process. Any ideas on what's going on?
Edit: Running into quite a few problems with LGNPST. Gets stuck at 85% and won't boot even after power cycle.
Edit 2: TeenyBin AltBin let me format my partitions and then the LGNPST worked. Got the OTA. Rooted again, used FreeGee, except this time with TWRP 2.5.0.0. Wouldn't reboot afterwards, so moved on to TeenyBin AltBin again. The phone booted up and everything runs fine. One thing to note: I had some wifi problems when I just TeenyBinAltBin'd and used a restore point for stock 4.1.2 which is why I was so adamant to LGNPST like normal. Still can't flash any of the newer ROMs of houstonn's, but I can others. On the good side, I still have a phone. Hopefully if anyone else has the issue, they can follow this and resolve it.

Attempted to update TWRP, stuck in download mode.

Hi All,
Today I decided to "update" TWRP to 2.8. I backed up the old recovery using Flashify, and then performed the update using the same. After a reboot I was treated to Download Mode with a 'Could not do normal boot' error.
I am quickly remembering that I used safestrap back when I originally did this after I got a Secure Magiccode Check Fail via ODIN in an attempt to fix things.
Is there any way for me to atone for sins, and undo the error of my ways?
So, I turned off the phone completely for about 30 minutes to an hour. After that, I started to charge it, and the battery icon came up. I turned it back on, and it jumped right into safestrap and continued working normally as if I had not mangled it. No idea why this happened, but hopefully this can help someone else.
You say TWRP, then safestrap. Those are two completely different things. Safestrap is for LOCKED BOOTLOADER devices. TWRP is for MDK ONLY. Be lucky that you didn't brick it.

My story of almost bricked into rooted, unlocked bootloader, and custom rom

I thought you guys might find this amusing, and hopefully it will help some people that get into a similar situation as myself. First, a little background - I rooted and installed Alliance Rom years ago back before the bootloader was unlocked. This worked amazing for me for a long time but I've recently had some weird issues with my phone so I decided to do a factory reset.
I went into settings, clicked factory reset, and then my phone got into a boot loop on recovery. I remember from before I had to do a regular boot then click recovery at the prompt instead of doing the factory recovery so I did that.
Instead of doing a normal wipe, I wanted to wipe everything on my phone and start from scratch so I did the full wipe (in what I think was TWRP or safestrap or whatever). When I went to reboot my phone it had a message like "are you sure? there's no OS installed" and I clicked ok. Well now I couldn't get the phone to boot into anything except download mode so at least I can use Odin.
I'm frantically searching google to try and find ways to install some sort of recovery so I could load AllianceRom again since I still had the zip file for it. Eureka, I found TWRP for my phone! I tried to flash TWRP through Odin but that doesn't work because my bootloader wasn't unlocked.... I remember this from last time ... all of the places I found online to install any sort of recovery required the phone to be booted into android.
So I'm clicking around and someone has a recovery randomly posted in a thread so I install it thinking, what the hell, what's the worst that could go wrong. So I install it through Odin and boot into normal recovery and I get this message saying my phone has been tampered with and to go to a verizon store immediately! Oops... upon further investigation (looking at the download screen), I tripped the knox flag... oh well, it's not like my phone is in warranty anymore (I got it on release day).
I search around looking for what I should do next and I found a thread that talked about being on complete stock, rooting, then unlocking the bootloader. I download all the files I need (newest firmware here - https://www.sammobile.com/firmwares/galaxy-note3/SM-N900V/ and thread here - https://forum.xda-developers.com/ve...guide-ob6-of1-root-bootloader-unlock-t3439010) to go back to stock and flash in Odin. Actually I didn't download from sammobile.com because it was downloading too slow so I just googled the file name and found it somewhere else faster, go figure.
Everything seems to be going ok then all of a sudden FAIL in Odin... Ahhh what the heck do I do now? Try again obviously! Second try works woo hoo! Phone start booting up, things are looking good!!! hooray!! But wait... it's taking forever to start and it's stuck on the Verizon logo... uh oh... taking way too long to boot up so I pull the battery and try again. Boots right in saying that android is upgrading so I think I'm finally in the home stretch here.
I try to run the ArabicToolApp for Root but I installed the latest firmware which isn't supported DAMN IT! Downloaded the correct firmware (OB6!), flashed in Odin, same problem before where it was stuck on the red verizon screen, pulled battery, rebooted, finally time to get root!
Phone finally boots into OS and I get a popup "unfortunatley com.google.process.gapps has stopped" great... and it keeps coming up over and over again after I hit ok... just my luck! Reboot again to see if that fixes the issue. Seems weird that I didn't have to go through all the initial setup stuff I did on the other version I installed... hmm... or maybe it was because I pulled the battery on the red verizon screen? Whatever. I somehow manage to get to options to do a factory reset and I let the verizon screen stay on a while this time. I'll go take my contacts out and give my wife some love while I wait
Come back and the phone is at the setup wizard, this is good news. Enabled USB debugging, installed root, done! Thank god!
Next I want to unlock the bootloader. I follow the steps here which aren't very clear (I'm guessing on purpose for novice computer users) - https://forum.xda-developers.com/ve...l/official-note-3-verizon-bootloader-t3359370
1. I installed eMMC from the play store to make sure my CID started with a 15, it does so I know I'm good to use the hack.
2. I installed both files in the unlock kit (adb and driver setup)
3. Fired up adb, navigated to where I had unlock_n3, and ran through the first part of the code once, reboot my phone, checked that the CID was the developer CID, and then ran the second part of the code three times before it worked
I verified the bootloader was installed correctly by trying to install TWRP through Odin, which worked!
I'm going to try out Jasmine Rom since it's a popular one that is on 5.0. My SD card only showed 30 megs free or something like that, so I formatted it from within android and copied the zip file over and installed the Rom through TWRP. Rom installed just fine, so I did one last factory reset which worked great and I think I'm finally good to go!
If you have any questions or run into any issues feel free to reply here and I'll try to help as much as I can.
Glad it worked out for you in the end.
From making a few mistakes I know that sinking feeling "oh no, what have I done?"
FWIW, the bootloader unlock method (in principle) works from nearly ANY ROM which is rooted - so, you would have saved yourself a bunch of time if you had started with that before you wiped the Alliance ROM. So long as you have root and a CID value that starts with 0x15, you just need root privileges - no need to return to stock and re-root.
(The "in principle" part is that there were several bugs in the "safety checks" portion of the unlocker binary that were sensitive to the OS revision, so you might have to search through the unlock thread to find a version of the unlock binary that is compatible with whatever rooted ROM is on the phone when the unlocking is attempted.)
good luck
PS The AryaMod ROM (w/ phantomOne kernel) is pretty solid - Marshmallow w/ S-Pen apps, too! As with any other dev ROM, there are a few sharp edges, but mostly everything works (except NFC).
