Rooted for a few weeks -- rebooted and stuck on T-Mobile Screen + Random Vibration

Hello all! This is the second time this has happened to me, I've rooted my phone for about a week, and then for some reason when I decide to restart my phone -- it no longer boots up. It is stuck at the t-mobile screen and vibrates for a bit then stops, I have booted in to recovery mode and tried wiping that cache, but to no avail.
Any help would be appreciated -- or even how I can backup my data would be great too.

Wah gwan! My T-Mobile S7 Edge running TekHD v2. To have your phone running very nicely, you need to download the APD8 fireware. Make sure everything on your phone running APD8. download the files from max on highonandroid, flash the tar file twice using modified Odin from max. Once boot up screen say custom, next step download and extract TekHD.rar file .there's a part in the file that operates like cmd, right click and let it do its thing. Make sure your phone is on and a low USB debugging.

Also this TekHD Rom is best for unlimited hotspot for Windows, Android and Mac. I have download about 20 more GB of files to make sure its good. The tutorial from max is good, the easiest way I see so far is to click on the root.dat in max files to add superSU. For TekHD click tekhd.bat. That was the easiest way after flashing the tar file. The hold process take 2 minutes once done right. I'm not a developer but a big Samsung Android fan. I have a Note 3,4,5 S6 Edge+ and S7Edge, I tried and tested many Roms at my own risk. Never had any problems. Make sure you always have the stock rom tar file for your device before any flashing any roms, is case something goes wrong you can start over.

first of all this is an eng boot root, so expect some hiccups and proble.. before u root make sure u back up everything then odin back to stock then root or else u will run into problems

You're going to have to ODIN back to stock. This seems to be happening to a lot of people (myself included) and a stock flash is the only way anyone has been able to recover. Flash all 4 files in ODIN simultaneously, but if you don't have a backup, try flashing the Home_CSC and see if it'll boot. I've heard reports that the Home-CSC file doesn't wipe your phone. If that doesn't work, then unfortunately you're going to have to re-flash, but this time use the standard CSC file, which will wipe your phone. Good luck.

I just had this happen for my second time and was stuck phoneless out of the house :/ I wish we could figure out the cause... Not sure if related, but my recovery has red text on the bottom "dm-verity verification failed"

No, that is not related, dm-verity verification fails because recovery still checks dm-verity even though the kernel does not.

Damn same thing just happened to me at work. Had to do factory reset...
When at that tmobile screen, hold down volume down + home button + power. It will reboot,and as soon as it does, switch volume down to vol up until it loads recovery to reset

This happened to me also. Go to lockscreen and security options and disable automatic security updates.

I think it could be new firmware update from Google. I tried to install TekHD Rom after update to the newest APG1. And it hapened to me also. Stuck on Samsung screen with random weird vibrations.

I can almost certainly say that the vibrate crash has something to do with the phone installing something behind the scenes. After getting the Amazon/Google/Samsung services multiple crash followed by the reset to the vibrating T-mobile screen I did a non-wipe ODIN, which works and works perfectly. What seems to not work though is re-installing root, it just leads back to the same screen, so I think Samsung is pushing something sneaky onto our phones probably through the security thing as mentioned.

TekHD Only works on PD8, it's mentioned in the thread.

Can't run that ROM on APG1. If you want to try it, you will have to ODIN PD8. There is a post in a thread in this section that shows how.

I just had this same thing happen on PG1. Using ODIN with all of the various parts and Home_CSC got me back in without having to wipe and everything survived. Going to try and re-root with the engineering boot image now that I made a decent backup. Would be great if someone smarter than me figures out what is updating/changing and causing this problem.

I said it on page 1: In settings, go to lockscreen, then security options and disable automatic security updates.

That might work to prevent this problem -- but what needs to be reverted once this problem starts? I can flash stock PG1 and if I use the (home_csc) it will fix the problem and not wipe my data.... but if I reflash the engineering bootloader it goes back to hanging at the tmobile screen.

im stuck on tmobile screen, and it keeps vibrating, idk what to do

I haven't rooted but if your stuck just Odin back to stock.

I came to post that I'm having these issues as well, this is the second time it's happened to me.
The first time I had TEKHD on my Phone, and so with it constantly nagging to do a system update.
I figured when it did this the first time, it was because the update ran over my TEKHD side load "ROM" and corrupted. Ok , whatever, reloaded.
But now I'm just rooted, and stock ROM otherwise. Just happened to me again
Each time it's happened, I start getting "playstore has crashed" errors - dismiss and it comes right back. So I reboot, and then it boot loops and gets CRAZY hot. Man I've never been able to fry an egg on a phone quite like my S7 Edge...
Is there any light shed on what could be doing this? I may have to remain stock which makes me want to :crying: but I can't keep bothering my Work Admin's to unlock my Token account so I can re-register my same phone -
I shall try that home_CSC Flash when I get home though, hopefully I can recover it at least in a way to transfer token to my tablet or something.

posted that at work, I'm at home now. I tried to flash just the home CSC and that did not work, just booted into recovery with an error and wouldn't resurrect at all.
I shall try that disable auto updates thing though and see if it helps in the long run...

you got a link for the home csc file you can send me I was good for about a month and a half and it finally happened to me as well and can confirm I was getting the play store/ google services errors right before the reboot and tmobile screen

Was having this issue as well, forgot that I needed to turn off Security policy updates.

Android N OTA from 6.0.1 stock - Services crash and phone reboots every few minutes

Hey Guys, I updated OTA to Android N from 6.0.1 (Marshmallow). After the upgrade all services crash (all google services including Messenger SMS) and the phone reboots every few minutes.
-Boot-loader is locked.
-No Custom Recovery Image.
-Oddly, entering stock recovery from boot-loader results in "No Command" error message.
Ideas??

Probably something went wrong in the update process and conflicted with something else.
Anyway: hard reset.
The "no command" screen is just a security screen and it's normal, you need to bypass it to enter to the recovery with a button combination (that now I don't remember, but I never remembered it even though I used to enter in recovery after pressing random buttons combinations lol).

Thanks dude. No worries.
Hard reset didn't work. Also tried to flash OTA from Recovery..
I was really hoping to avoid the stock ROM.
For now, I unlocked the bootloader, installed Recovery, and then loaded Stock ROM. All is well under Stock ROM.
Will try again tomorrow.

Press power + volume up to get recovery menu.

Was having a similar issue. I'm all stock, unlocked bootloader. Signed for N preview and instantly got the OTA download. It installed and pretty much within a few minutes the bootloops started. couldn't even power down without it rebooting on its own. I got it to power down without turning itself back on through recovery/power down. I let it sit and cool down. Upon reboot.....was doing well, and started to boot loop again. I REALLY did not want to factory reset.

Thanks dude, but not a newb. Not using my old account, which I should recover.
I had no issue restoring to stock after unlocking bootloader and flashing Recovery. Strange that the OTA via beta is unstable for some and not for others. Even after a reset of OTA, the services and reboot issues continued.

So for me, a factory reset and setting up a brand new phone (no backups of any kind....even from Google) have seem to do the trick. Unfortunate that I lose my wifi password backups. Asking some people for their wifi passwords again is a PIA. Especially the ones who don't know them, and it's a 27 key password from their cable company. Anyone know how to pull just the wifi backups from google?
My thought is one app or setting was causing my problem so I'm slowing adding everything one at a time. PIA really. I don't miss the Froyo days that's for sure.

Wi-Fi forgotten on reboot or when Wi-Fi turned off

So I have android nougat [rooted] but when I reboot or turn Wi-Fi off then back on it doesn't have my Wi-Fi networks saved. I have already set ro.securestorage.support to false and it still will not work. Have a screwed something up? I just installed this a few days ago..

It is a known bug with the eng root method, i can't remember the fix. Search the root thread and you'll probably find it

Part 3 is what you're looking for.

I know my replies can be long, but would rather give too much info, than not enough.

OK so it's all fixed but now i get 3 reboots before i even get into the system.. Any pointers?

Not sure if it'll work on stock rooted but on some roms you need to boot into recovery, wipe system/data, once rebooted and set up run the latest supersu root.bat. i belive the latest version is 2.79.

I figured out what the rebooting was from. What happened was 'master.sh' was rebooting after the sh files did their jobs, but i guess one of them wasn't doing it's job so it kept rebooting. The 'master.sh' file has a 'failsafe' where if it reboots 3 times (defined by 'reboot.count') it will cancel the reboot. I thought it was just some issue with 7.0, but while it very well could've been, i flashed the stock AP again but this time put the engboot in CP and it fixed itself after i reinstalled su.img essentially.. Can't imagine how Android 8.0 would react to EngBoot and su..

N910F stock crash and bootloop after 6.0.1 update

Hello people of the world,
after reading a lot of posts here I still can't fix my phone's issues, so I need to post. Bear with me...
I have an N910F which was entirely stock and functioning without problems. Two days ago I accepted the official update. After that, the phone regularly lost connection to the mobile net, froze, and restarted. It would work for a short while until it froze and restarted again and again. When I tried to use the camera, the live picture was completely distorted. The phone crashed and has then gone into a bootloop.
I pulled the battery, did a recovery start and wiped the cache. No difference. Factory recovery next, no difference.
I have since tried several stock and custom firmwares, always taking care to follow instructions and use the correct bootloaders, modems, etc. TWRP is working.
When I flash a stock firmware, it will go into a bootloop. With any custom ROM, it will crash during startup (logo) and switch off.
Any help would be greatly appreciated!

Protect the eMMC?
So, after more reading I began to suspect that the eMMC had moved on to the valhalla of electronics. Sent my phone to service where my suspicion was confirmed. Luckily, they were able to replace the chip without having to put in a new board.
Is there any way to prevent this kind of failure again, or at least make it less likely?

Yes this is a known issue after latest update you could you install only one application called wakelock so that your phone doesn't reboot and CPU keeps awake

Thanks! I had read about that.
Got my phone back from service today, they had flashed stock 5.0.1. After checking that it worked I flashed RR 5.8.4 and installed Wake Lock Powermanager. I searched for a comprehensive tutorial on what the settings do and which to use. Right now I set it to PARTIAL_WAKE_LOCK (4) but I'd like to read more about it. Any tips on that?

installing power wakelock and setting up on partial wake lock is enough.if you get trouble in starting your phone remove its battery and put your phone in refrigerator for five min.and try to start your phone.this problem also related and happens after the latest update

7.0 Update Crashed my Device. Custom Roms won't take. Stock Rom crashes, too

I received an update push from Motorolla that installed Nougat. After that, my phone would crash every 3-10 minutes. I did all the troubleshooting I could find online. I contacted support and they wanted me to spend $150 to get it "refurbished." Of course, it sure seems like a software problem, so that wouldn't help me anyways...
I turned to custom. After rooting, installing SuperSU and TWRP, I couldn't get several versions of AICP or Lineage to ever boot (stuck on loading screens). I also tried all the advice from this thread.
I went back and installed the stock Rom using f2fs , and the phone would get to the "hello moto" part of the boot up, then crash and reboot. I tried again using EXT4, and it worked, but just like before I ever begun, my phone was crashing every 3-10 minutes. However, the first crash wasn't until after I made a phone call, and my phone had been crash free for about 20 minutes before that call.
I'm a I.T. guy, but I'm not a "phone" guy. But it seems to me that there must be some other software that was modified during the update that is causing the problems that isn't part of ROMs. Something in the Kernal, or a driver folder or something?
Also, is there a way to get crash reports? So maybe if I at least go back to the default ROM and wait for it to crash, I have some info to work with?
Any help is greatly appreciated, thanks!

Flash full stock 6.0x for your model/region.
Important:
Without bootloader, gpt. Don't try locking BL.
Links you can find in my signature.
Try normal boot and after success any custom.
You cannot allow any ota update after it.
Some customs are only for Nougat modem/radio - don't flash it. @Kaivian

Ok, I got most of that, except I don't know what gpt refers to and am not getting any hits on search.

My signature - flashing stock - without bootloader & gpt.

So, I installed a 6.0 stock ROM and got tons of errors. I tried a 2nd time, still got tons of errors. Needless to say, stock 6.0 didn't boot. I decided, "The heck with it" and tried installing Lineage 7.1 again... and it worked! It finally booted up entirely. However, now I get a "Sim card missing" notification. Can I just reinstall part of something... like the modem? so I can keep this "working" lineage boot? Or am I starting over yet again?

Repeat
from
fastboot flash modem ...
to
...fsg.

This caused it to not boot.
I went back to 6.0 and turned off auto-updates. I'll try again sometime when I have time. I did like the custom rom a lot, just couldn't use it as a phone xD
