POCO F1 boot loop issue - Xiaomi Poco F1 Questions & Answers

Hi, my name is Vinicius and I'm from Brazil. I have a Pocophone F1 since October's 2018.
So, I was using my POCO F1 normally then it turned off and decided to boot loop today. It doesn't load the system, and I had never rooted my phone (it's a virgin POCO). I followed tear-down videos and seems the processor is overheating in this boot loop. I have disconected my battery from the mother board to avoid damages.
Then i googled boot loop issues about poco. I conected battery again and tryied holding the power button and the (-) button, and something happened but it started the loop again and now it doesn't show the poco's logo, just the mi assistant tool, then turn off and turn on loop again.
I really didn't did nothing to be in this situation, and I don't know what I can do with this, because I really need my phone and I can't afford a new one now.
Is there anyone with this issues too? How can I solve this?

Same Issues!!
:crying: Hey bro! Did you solve it?
My Poco f1 started to have this restart loop problem now. Couldn't even get to recovery. The recovery itself is restarting in a loop. I'm just a normal guy unlike you. Is there any other problem with the button thing. Cause it already happened once but I tried to restart again and again for multiple times it worked. Now it's not working at all even after many times. Is there anything I can do?
I am so frustrated bro. Help me out.

Just Flash the fastboot rom using Mi flash tool.
And it will start working fine.

I was trying to do this, but the problem is that I enter the download mode, then the phone restarts 5 seconds after. It's impossible to use Mi Flash Tool.

how to save data?

Was there a solution to this issue?
My phone (POCO F1) running Pixel Experience 10 Plus got into a boot loop last night. I had updated to PE ROM many months back. No updates recently.
Phone keeps o looping between blank screen and POCO logo screen. Unable to get to recovery. Even when the recovery button combination is pressed, the loop continues. Unable to turn the phone off. If the battery runs out, the phone gets into this vicious cycle again when it's connected to a power source and has enough charge to get going.
Any suggestions on what could be a way to recover the phone? Totally at a losss now :-(

Faced the same issue while flashing pe10 rom. You can try formatting data after flashing the rom and also try clearing cache. It fixed the issue for me.

Need help with g2x!!

So, I've had my LG G2x for about a year now. About 2 days ago it stopped working. So I tried rebooting it manually (Power and Vol.-). It worked! Later that night the phone stopped working again. I have tried rebooting it many times and have given up on that. So I tried One-Click Recovery Flasher to try and reboot it. I have tried all three flashes ( 4.0.1.5., 5.0.2.0. and the Stock) and then I try rebooting in the flashes and the LG logo pops up and then the screen turns black. And it's a loop so it just pops up and goes black again. Is this fixable? If I flash it with Stock and go to T Mobile can they fix it? SOMEBODY HELP!!!

[Q] SGSIII reboots just after start.

Hi. I have a SGSIII which doesn't work properly. Its previous owner told me that the phone had started work slowly so the owner decided to restore factory settings. After that operation he was not able to use SGS. It keeped restarting. He gave up and now this telephone belongs to me. When I try to run this phone telephone restarted as soon as the system started. I decided to flash SGS with stock firmware. I found the one which contained only one file (PDA). Unfortunately it didn't help me. Then, I installed CWM and CM11. But the problem still wasn't solved. Finally I decided to find four-file stock rom (Bootloader, PDA, PHONE, CSC), of course I still have the same problem. I've been looking for solution in the Internet and I'm afraid that could be hardware problem, what is more, it seems to be common. Do you, guys, have any ideas what can I do to fix this issue? Or can you confirm that is the hardware problem? Thanks in advance.

Dont know much but as long as the phone boots i dont think it should be a hardware problem but still it can be. Did you try takimg it to service?

Well I haven't tried taking it to service, because I am not sure if it is worth to repair this. Replacing the motherboard will be expensive so the better way will be buying another phone.
It could be a stuck power button... that can cause bootlooping type behavior. If the phone turns itself on when you put the battery in, but then reboots before it gets done booting it's likely the power button.

I don't think so the power button is guilty, becaue the telephone doesn't turn itself and it doesn't reboot until Android starts.

Phone boot loop. Restoring phone works, but then restarts and boot loops

Hey everyone, E2303... I recently replaced the screen because it was broken, but now it boot loops. I can restore to a different ROM using Flash tools and it comes up fine after, but during the setup of the phone (choosing language, etc...) it reboots and goes back to boot loop.
So strange. Anyone one know what could be causing this?
Thank you!

When flashing ftf, have you tried wiping the system and data?
Yes, and the phone boots up normal. I recently put it in the freezer and it actually makes the phone work for a while, and the it reboots. I think it is the processor over heating, any idea how to fix that?

RN3 Kenzo - replacing motherboard to unbrick

Dear Redmi Note 3 experts,
I have totally hard bricked my Redmi Note 3 trying to unlock unofficially. No hardware damage, only hard brick.
I was wondering if it is possible to bring it back to life by changing it's motherboard.
Is there a recommended place online to buy a mother board or a service center I can ship this to replace the mother board?
Does this even make any sense? or is it even possible?
Appreciate any guidance
Use test point mathod it will be back in life easily. Tested myself

can you boot to fastboot if yes then flash via fast boot or search for FASTBOOT TO EDL MODE IN guide news section and flash via EDL that might help

If you're unable to boot to fastboot and edl or the pc shows 9008E, get the deep flash cable from Alixpress. It's cheap and easiest way to recover your phone. This cable works fine.
https://www.aliexpress.com/item/New...rts-all-BL-locks-Engineering/32785943419.html
Or you can make the cable yourself with some Youtube tutorials posted above.
I can see 9008E. So I just bought a deep flash cable and was able to flash global stable rom with success message.
When I pressed power button, nothing happened.
When I pressed -vol+power, nothing.
when I pressed +vol+power, nothing.
Then I pressed -vol +vol +power together and the screen showed mi logo and android logo at the bottom. Attached​ picture. It's been like this for 30mins already. It doesn't seem to finish booting. Should I wait?

Wait a bit more and if nothing happens try rebooting to fastboot.
If fastboot is accessible try flashing the latest dev rom.

Did you flash all partition including storage? If I remember correctly, this shouldn't take more than 10-15 mins to boot up or even less. If it's still stuck, you should select 'flash all including storage' in Mi flash.
Or
Since your phone can boot into fastboot now, I would suggest to unlock it unofficially and flash zcx twrp recovery and than flash the rom through recovery after formatting all data.
Device booted after flashing Chinese developer rom. However, another issue seems to have sprouted from this.
There is a prompt saying "Cant Get Valid Device ID"

You lost your IMEI and Modem. Try this -> https://forum.xda-developers.com/redmi-note-3/how-to/flash-recover-efs-snapdragon-t3406789
My phone box has only one IMEI code. I was able to restore that imei to the sim 2 slot. sim 1 slot has some unknown imei1.
However, after much effort flashing many roms trying many methods for efs/imei restore, i was not able to get the sim cards working. none of the sim slots work.
Does the "Radio: OFF" status mean it's being kept forcibly off by the system. i looked for an option to turn it on with no success...

U did somethibg wrong..u have to use imei fixer and input your own imei given at the back of box..dont.input some random imei..imei spoofing is illegal
I have also lost IMEI, sent to service and motherboard was changed with IMEI. The problem is the new motherboard, which keeps rebooting, suddenly and randomly. When starts to reboot, it never stops and keeps rebooting on Mi logo - never get to loading MIUI. Even if I flash the MIUI (global) again through EDL, same thing happens. After some time, it will revive again by itself and starts booting. My fault is I didn't backup nvram with the build came from service, but with global stable after I have updated.
It sounds as a hardware issue, or it could be resolved by some software flashing/modification?
@Yogendra Kher Do you have any issues with new motherboard?

Bootloop LG G5

My phone turned off a few days ago and it's now in a bootloop, I've tried a lot of things, without any positive results.
When I try to get into download mode it appears for only a few seconds and then it enters in the bootloop again.
The only thing I have access to is to the fastboot mode but i don't know if I can do something useful with it.
Can anyone help me please?
Sorry if my english isn't good enough btw, i'm from Chile.
Thanks.

Well, I tried the common things... LG UP doesn't detect the phone because the download mode restarts after a few seconds. In fastboot I tried to patch a new sofware with some guides in this forums, but I realized that the bootloader was locked so nothing happened.
