Phone does not boot often - Xiaomi Mi A1 Questions & Answers

Dear all,
Right now I am facing an awkward problem.Usually I charge my phone when its turned off.Sometimes I am observing that whenever I powered on the phn it just stucks in "bootloader unlock warning message" and the ROM does not boot up.
After that If I hard reboot then rom boots.This situation occurs often.
My phone is 1.5 months old and using official RR ROM.No problem with power button.
Can anyone tell me why it may happen and how to solve it?

Phone keeps restarting at recovery screen

Hi guys,
I have an issue with my phone:
Yesterday, tried to restore factory settings, since the phone was quite slow.
A second or so after I confirmed the reset, the phone turned off and wouldn't start.
I took out the battery and it was swollen.
I bought a new battery today, inserted and stated the phone.
What happens now, is that the phone boots, Samsung logo appears, then the TWRP logo appears, from this point, the phone stuck at this logo screen,
and flashes every few seconds (I can't post a video here, so I can share the link in private, if anyone can take a look).
I tried to leave the phone for about 20mins without battery at all, removed SD cards, removed SIM cards, no use.
Trying to boot to recovery or download mode gives the same result.
Tried today with an original battery of a friend's Galaxy S4 , same result.
Does anyone have an idea what I can do?
Thanks in advance for you help

Sound to me your power button is stuck/faulty. Does it reboot also when in download mode? If so, then it's your power button. Wiggle it loose or replace it.

It never gets to download (or recovery) mode...
It keeps flashing at the logo of the TWRP
Trying to boot to download or recovery modes, gives the same results
I don't think it's the power button. Otherwise it would turn off if it is stuck or not turn on at all if it's faulty.
Still, I wouldn't exclude it.
The screen flashing might related to a GPU problem. I don't think it is a problem you can fix yourself.

Trouble flashing marshmallow roms

Hi all
I'm using a snapdragon n10g note 4. Whenever I finish flashing any android 6.0 ROM(with factory reset and everything) I get the following problems:
The phone shuts down at the boot screen-while the boot animation is playing. Not restarting or anything,it just shuts off. I can try to turn it on again but it just shuts down again.
Then, in the rare occasion that it DOES boot successfully, I get a "no sim card detected". And I can't really reboot to try and solve it because the first problem will show up again...
Have googled a lot but didn't find anything. Thx in advance.

Rn7 global died all by itself

The phone rebooted by it self, no firmwareupdate going on, just random reboot.
Got stuck on redmi logo.
Could reboot and get fastboot, but could not flash original fastboot rom, got errors. a normal reboot gave only redmi logo.
Now the phone is out of power, not taking charge, not powering on.
Anyone have any solution for this problem? Or any tips? The phone is stone dead
Not sure if this will help...
here's my random reboot thread and fix
Well, i have no simcards or sd-cards inserted.
And its not charging or turning on. volume up and down + power is not making any results.
The weird thing is that it said "redmi" on the display for about 24 hours draining the power, and after it died out of power i'm unable to do anything with it. its basically a brick.
This happened totally random. just a spontaneous reboot into a never ending redmilogo.
During redmilogo i had the posibility to get it into fastboot by rebooting it, but mi flash would not accept the phone. so another reboot into regular boot ended in infinite redmilogo again :|
Your phone's bootloader unlocked?
Nope
Did you try keeping it charged for a while? Device might not show any sign (charging indication) but the battery will get charged eventually (I guess).
Charge it well and try to SIDELOAD that FASTBOOT IMAGE via PC..
It loooks like its bricked all by itself. i left it in charger for days.
I got contact with the phone with mi flash, but it has gone into some authentication mode with the flashing, so i'm not possible to reflash rom without authorization.
Read about this on reddit, and it seems like a dealer has to look at it.

suddenly boot-loop, maybe after phone fell

ok
i've been usign whatsapp and suddenly my phone went into bootloop,
tried to enter fastboot, recovery
but he keeps on boot-looping after 2-3 sec of showing the fastboot-recovery icon.
i tried disconnecting the phone-battery-motherboard-etc, but he keeps going boot-loop, showing the first load screen, black screen, and so on and forth
any suggestions? never occured to me before , only after unsuccessful flashing, but like this? this is really weird.
i have a custom rom yes, but with it for a few months already , 0 problems.
p.s my phone fell on the floor few days ago, but had no problem since whatsoever
any clues on how to solve this?
i can't even get to flash via fastboot/recovery because it restarts when im there..
what could be the problem? the only thing pops into my head is that the restart key is pressed all the time, but is it possible?
I had the same problem, crazy thing. I couldn't even enter orange fox, got to the loading screen and got another reboot. I pressed power button fast many times and then worked. The power button seemed to be ok. The only thing that i had recently changed was the EAS version of the predator kernel. It may not make sense but i went back to HMP and now it's fine.
well! it worked lol
what is HMP? a kernel?
A type of kernel, the common one. Now i know that was not the reason!
Hello
I have the same problem as you and if someone has a solution, I will be very grateful !
I can use my phone but if I push to the power Button, it bootloop.
