[Q] Reboot Loop, No Recovery, No CWM - Android Q&A, Help & Troubleshooting

Phone: Motorola Droid Maxx
Rooted
Problem: After accepting 12.15.15.en.us update, phone powers down, reboots, reaches home screen from between 30 seconds to 1 minute, then reboots again in the same fashion, nonstop.
Agreed: I should have never accepted that damned update.
I can access TWRP for about 10 seconds before it reboots again.
Can't find any backup files.
Not sure if it would even have enough time to backup, before rebooting, regardless.
I have tried holding the Vol Down key to reboot into menu. It tells me that my "Device is LOCKED." So I guess I lost root (?).
From there I selected "Reboot into Recovery" but it doesn't change anything - simply reboots into Home Screen again.
Considering a Factory Reset but not sure that will do anything.
What to do?
Please help.
Edit: Tried booting into "Factory" but it just took a long time to reboot and then nothing changed.
I'm sunk!

me too having the same loop of starting problem

[Q] Stuck on splashscreen and hard-resert dosen't work?

Hey, I've just installed the ViperDNA rom and tought I would try it out. I've installed everything correctly with TWRP and Aroma showed me everything was installed fine.
Now I am booting my phone and I've noticed it was stuck for over 7 minutes in splash screen, so I tought okay I will do a hard-reset. I've pressed over the home button for a minute and the it didn't restart, the panel was flashing but it didn't restart. I've tried to click on other buttons and all but it didn't work, I've connected it to the PC and tried to find it with ADB and it showed the device is not connected. The battery is full and it's in the splash screen still, how could I possibly restart the phone?
- ADB dosen't find the phone
- Tried to check if suddenly the phone is stuck in fastboot (sometimes happend with my old phones, unknown how)
- Tried to press the home button for over 1 minute to restart when it should be 10 seconds.
Anyone knows how to do something? I am hoping my battery will run out somehow like this, but untill then. I need some suggestions.
Hard reset is holding power button for 10secs not home.
Sent from my DNA using my mind.

[Q] VS98012B - Stuck in boot loop. Can't flash.

Hi guys, so I've been digging through a ton of posts on here trying to solve this problem.
I have a VS98012B a.k.a. LG G2, it's stuck in a boot loop.
LG Logo displays, then the Android on his back with the red triangle, one minute later the screen goes black and the process starts all over again. Here's what I did leading up to the issue:
I rooted the phone with ioroot24.
Root was successful.
Used Root Explorer to change permissions on the SYSTEM folder. (I was trying to change the .ogg system sounds to custom ones.)
I was prompted that I would need "Superuser" status to do so.
The launcher app, and half a dozen others crashed over and over. I couldn't power off the phone or anything. I could only press OK everytime the box popped up every second. So I attempted to hard boot the phone with the POWER button, and here I am in this boot loop.
I tried using the LG Software, and a .kdz file for a VS98011A. The USB drivers are the latest ones for the phone. I tried rolling it back thinking it might help to have an older version, but couldn't find the device driver to roll it back from.
The LG Software will attempt to restore it, but since the phone keeps rebooting, it never gets a chance to perform the install.
I tried to do a factory reset, holding VOL DOWN, then POWER, then at the LG Logo I release the POWER and hold POWER down again while still holding VOL DOWN.
The dialog comes up to reset it, I tap POWER 3 times, the screen goes black, The Android with the Blue Orb comes up with a loading bar, but it disappears after about 3 seconds, and the whole boot loop continues.
I'm about to kill myself. Please help if you can. T_T
Please close this thread. I found out how to put the phone in Download Mode, which took it out of the boot loop, enabling me to finish the process via the LG Mobile Update Tool.
To enter Download Mode, you need to hold the VOLUME UP key.
Surprisingly, the older 11A version was a placeholder for the actual Recovery data that was used for my phone-12B.

[Q] HTC One M8 keeps rebooting after AT&T Software Update

Hi, android noobie here, I have a rooted m8 that keeps rebooting after updating the at&t software.
I get the pop up that says AT&T software is available. If I clicked on continue it reboots to teamwin during boot up and once i reboot to system it just reboots itself every 30 secs or so.
I had to do a factory reset just to get my phone working again. But now the update screen is popping up again and I have to keep it under 35% so it doesn't auto update and keep pressing remind me later.
How do I disable this auto update? or is there an easier way to make the phone go back to stock since I really don't have any use of a rooted device besides watching MLB games...
Thanks for the help.

If I'm not mistaken, you would need to un-root your phone prior to installing any OTA Updates from AT&T. Also, you should only install the OTA Updates while using the stock recovery. So, you should re-flash the stock recovery and then attempt to complete the OTA Update. After that, you could re-install TeamWin, re-root and prosper.
Refer to this link on reverting back to stock... http://forum.xda-developers.com/showthread.php?t=2721435

Good rule of thumb, do not install OTA updates on any modded Android device, without at a minimum doing thorough research on what will happen.
Depending on the device and the update in question, attempt to install an OTA on a modded device will remove root, possibly plug existing exploits (and render the phone unable to be rooted), or put you in a boot loop (as you have experienced).
In particular, OTAs require stock recovery in order to install. So if you have custom recovery installed, this is why the OTA install is failing (and why it keeps booting into TWRP).
Also, there is little (if anything) contained in the OTAs that doesn't get posted in a safe format (flashed from custom recovery) in the Development section soon after the OTAs start to roll out.

Hi, i have a HTC One M8, and when my first update popped, i was very enthuziast.
I accepted to download the update, installed it, and... the problem appeared. The phone made his restart after update... and continued to do so over and over again. (Vibrate/HTC screen on for 30 secs/screen off and so on)
I checked the HTC website for solutions, i entered live chat with a consultant, and he asked me to start the Hard reset procedure. To do that, while turned off, you have to press both volume keys, and press the power button. The phone will enter in the Bootloader menu where you have some options. But... tell me, how to do that if the phone restarts continously? you have about 1-2 seconds to do that, while the screen is off. It gave me a hardtime to do that... Finnally, i managed to enter the Bootloader menu.
There... you have 2 options: (using volume up/down to select, and power button to select) you can select to poweroff(shutdown) the phone - and the phone will shutdown,
or you can turn off the fastboot, and the phone will restart normally.
The thing is that when you restart your phone normaly, while fastboot on, the phone skips some steps, and go directly to to turn it on and show you the startscreen.
When you make a major update, like system upgrade, when the phone restarts, he needs to load all the boot setting. And here is the problem. If you have fastboot on, and make a major update, the phone will enter in this ****ty cicle of continous restarts.
Remember to deactivate this Fastboot before you update!

This is not correct. To force a reboot, you hold power and vol up (not both vol buttons). Then, when its restarting (the moment the screen goes dark and before the white boot screen appears) you let go of both those buttons, and only hold vol down.

In the case of a bootloop (phone keeps restarting), all you need to do is hold vol down during one of the reboot cycles. The timing doesn't matter in this case. Just sit on the vol down button until the bootloader screen appears.

First, the FASTBOOT selection in bootloader is not the same as "Fast boot" in Settings>Power. The latter just makes the phone start faster from power OFF. The former is an adb (Android Debug Bridge) special mode that allows you to flash partitions from a computer.
Second, in bootloader, you should have the following selections:
FASTBOOT
RECOVERY
FACTORY RESET
SIMLOCK
CHECK SMARTSD
IMAGE CRC
SHOW BARCODE
Of course, its the FACTORY RESET option you want if you want to wipe the phone. Scroll down to (using vol keys) and select with power button.
On the bootloader screen, the active selection is the blue box with white text below the green phone info (hboot number, radio number, etc.). FASTBOOT should only be the default "active" selection if your phone is connected to a computer by USB. Otherwise the default selection in bootloader should be HBOOT.
Third, the "Fast boot" option in Settings>Power does not make a restart "faster" by skipping any steps. It just makes a start from power OFF faster. Its kind of a trick, where power OFF is not really off, but just a deeper sleep mode. A restart is always a restart, regardless of whether "Fast boot" is selected or not in Settings>Power.

Lenovo TAB S8-50F stuck in boot loop

I have Lenovo TAB S8-50F that is currently stuck in a boot loop. It shows the white Lenovo and "android" text on black background boot screen for 30 to 60 seconds, then shuts off, vibrates and the screen flickers some white color and then goes back into the Lenovo and "android" text boot screen and repeats.
After some investigation on these forums and Google, I have tried the following:
Hold down Power + Volume Up + Volume Down until I see "fastboot starting...". I wait 5 - 10 minutes and it still says "fastboot starting...", nothing else. I try to connect to my Windows 8 laptop but it doesn't recognize the device.
Hold down Power + Volume Down until I see the boot screen, then let go of Power (keeping Volume Down pressed). Apparently this should boot into a Recovery menu, but nothing happens and it continues to just turn off after about a minute and boot loop
Hold down Power + Volume Up until I see the boot screen, then let go of Power (keeping Volume Up pressed). Same result as above, it still goes into boot loop.
During any of the 3 scenarios above, I can turn off the tablet by holding Power + Volume Up. Also I never saw any other messages like "EFI failed" or "No mounted drive" that other users had problems with.
Is there anyone out there that can help me restore this tablet back to functional state? I'm not sure what happened that caused this to happen.

Okay so first of all i will let you know why a phone gets bricked-

my case
i always keep two phones with me like one for my experiments and one as a backup. In this case i'll be talking about my lyf wind 3 that got bricked.
>actually i was trying to install twrp onto that phone but first i had to root it, and due to the upgraded android security, i wasn't able to do via kingoroot so i tried i-root and it did the job but instead of kingo-superuser i got some ****ty superuser so i tried granting permission to the actual superuser and while doing so i accidentally double rooted my phone (first with i-root and then with kingoroot), which was kinda stupid, so it just deleted some system files and my phone wouldn't boot after that. It just got stuck on the boot logo.

Realme 1 random bugs/issues after Software update C.49 (May 20th 2020). Plz HELP

After I updated to C.49, my phone is acting weird...
1) Power Button is not working properly
2) Random emergency Call Screen and Power Reboot/Off Screen.
3) When I tried hard rebooting to go into recovery....it shows recovery mode at bottom for 10s and the reboots again to recovery mode text at bottom. It does not go into Menu of selection of English and Chinese language. This continues infinite times...Until finally it decides to boot to main home screen. But the Power button and Emergency screen/Reboot screen issue continues..
4) I tried factory reset of system setting...Same issue remained.
5) I finally tried factory reset wiping all data..Since the Version is latest C.49, which I believe has issues, the Emergency screen and Power Reboot Screens and Power Button not functioning properly continues..
6) I downloaded CPH1861EX_11_OTA_0490_all_sWtP8RDIvyoU.ozip from realme support. Tried updating that software in the phone..
But it lead to point (3) which I stated above...Same vibrating/rebooting after every 3 to 5 secs but not going into recovery Mode..It continued for 1 full day until battery died..Then I charged the phone for sometime and it continued its same funky routine of infinite rebooting and stopping at recovery Mode text.
But, eventually, after few hours, it booted normally to main screen.....But the problem was still there.
7) Now, even if try to shut down..from Power reboot/off screen...It shuts but in few seconds reboot again to main screen. So I cannot even shut it down.
8) I may try to download C.48 version (2.16 GB) and update from SD Card somehow..I don't know if it will revert back to different Version...But gotta try.
Or if there is enhanced or latest or custom update newer than C.49 available in market. maybe I should root or install that.
Frustrating...
How to get rid of this bug? I guess have to wait for new patch or something or next update. Service Centers are not open..because of Lockdown in Mumbai.
Please help, if someone knows the solution or had to deal with similar issue.
