[Q] Can't Reboot into recovery, Q-mobile Noir A10 - Android Q&A, Help & Troubleshooting

Hello Everyone,
I have Noir A10 by Qmobile and since morning I am having this problem. I had installed JMP ROM v 8 and it was working super fast for atleast a month or so. When I got up in the morning, I saw the wait logo(that appears when I boot up the phone). I waited for a few minutes but phone was stuck there. I tried to restart but it didnt respond. I took out the battery and turned it back on. It did turn on but display resolution had a problem. I could not see whole the screen. For instance when I browse to Application drawer, I am unable to see some of the Icons. I reset the phone to factory settings and restarted but had the same problem with display. Then I tried to reboot into recovery but it simply resets the phone to factory settings instead.

Vol+ Vol - and power button, release power button after it vibrates but keep holding volume buttons and at last home button your phone will reboot into recovery.... and even if you flash another rom the start up logo ll remain on your phone so if you want to get rid of it you ll have to delete it from temp fold " logo.bin"

[Q] Hanging S2

Hello,
I rooted my S2 some time back with no problems and removed some Samsung bloatware. I did not install a custom ROM but did use Triangle Away to remove the start up screen. It's rooted with the Siyah Kernel
My issue is not with boot hanging, but hanging after starting,
My phone used to hang every now and then (twice a week) and a simple battery pull would solve the problem. Pull battery, reboot and it's fine.
Today, my battery ran out, and I placed it in charge and removed the phone after charging. My phone starts up fine, gets pass the Samsung logo, Siyah logo and I get my home screen. Here is where the problem starts.
I get the usual start up notifications e.g. "preparing USB storage", "power saving mode enabled" etc. I can then use the phone for roughly 4 seconds before it freezes. The touch screen does not respond. It freezes. The only thing that does work is pressing the home key 4 times to get negative colours. Apart from that, nothing. If I press the sleep button, the screen goes black and the phone is off. I restart and I get the same problem all over again.
TLDR: Rooted phone, hangs at homescreen upon boot, no custom ROM, battery pull doesn't work
Any help would be much appreciated!

Prestigio 4500 stuck in Bootloop

Hello, 5 monts ago i flashed and installed a new ROM on my Prestigio Multiphone 4500. It worked fine except some minor low memory issues but it didn't bother me too much. Today I decided to factory reset my phone. I backed up all of my data and went into options and factory reset, after that my phone turned off for a second. after that I noticed it only shows the bootup screen and the android logo with a blue bar moving underneath it.
I tried the Volume+ and Power button but nothing, after that i pressed Power and Volume- , it launched the phone in factory mode but no option to format or anything. one of the few options were PCBA Test, Full Test, KB Test , Item Test , etc...
After that i formated my memory card but still didn't work.
Please help

Lenovo K910 keeps restarting endlessly.! PLEASE HELP

Hello,
This is my first post so i hope that this is the right place.
I have a serious problem. My K910 is endlessly rebooting.
It all started after i updated android from 4.2.2 to 4.4.2 When device rebooted after installation it never came further than lenovo logo.
When phone turns on, it vibrates, then lenovo logo comes out for 2-3 seconds then it dissapears and the loop starts again.
it shuts down only when i push power button and volume- button multiple times.
I have tried to enter recovery/safe mode, but with no results phone keeps rebooting.
I reinstalled battery but still as i turn the phone on, same problem occurs.
As soon as i connect my phone to pc phone turns on and endless loop starts again.
Questions:
How can i change to stock ROM or connect to PC in this situation since it keeps on rebooting my pc doesnt see added device?
What can i do to fix this situation?
Please Help.
I promise $feedback if this thing can be fixed

That means your phone is in bootloop. Try opening recovery and wipe cache/data . If you got a custom recovery, then its much better.
Hello,
Also i experienced similar problem with a defective battery,
after i removed it too much,
fixed by replacing it,
hope it helps.

Please help me! [SM-G920F]

-So i recently bought a Samsung S6 (SM-G920F) and it came with android version 7.0 Nougat. I wanted to root it and put TWRP into it as well but before that i found out a Samsung S8 rom, (the stable version):
HTML:
https://forum.xda-developers.com/galaxy-s6/samsung-galaxy-s-6--s-6-edge-unified-development/noble-nougat-rom-1-0-t3565293
-And it came with Magisk 14.0 so it had root as well, i did have the twrp before i got s8 rom, and it was looking pretty fine for like 2-3 days but after some time , i was normally looking up on youtube and my phone just froze up and started making weird noise, screen did not respond, neither did volume keys neither did power button, nor home button, since my s6 has a non-removable battery ,i forced it to shut down with holding volume down button+ power button, and it just kept restarting but it always got stuck into some point before it could be booted, like in middle of samsung logo, in middle of showdown of twrp recovery, i only had access to download mode. I searched the problem in google and found 0 answers about this problem. So i tried to put a full factory rom for SM-G920F using odin v3.12.3, and it was looking good, it passed the test, rebooted to recovery immediately without me touching anything, and it got stuck after i hit restart, then i again forced to shut it down, so it did, restarted and again stucked at recovery android logo, sometimes it goes in the recovery and i tried wiping out the cache and data, but that did not work either.
-I would really need your help, because i lost a phone 2 months ago with the same exact problem but i did not put any rom only root (it was a samsung s4 mini) and i do not want to lose my second phone :/
Thank you.
