Facts:
- Pocophone F1 is in an endless boot loop. Every 8 seconds it reboots itself.
- Recovery mode and Fastboot are reachable, but this doesn't stop the boot loop.
- I have never used a custom rom
- The bootloader is unlocked (ADB confirms this), USB debugging is enabled, but OEM unlocking is NOT enabled.
History:
The problems started after a regular update (I had never put a custom rom on the phone). The phone became unstable, constantly restarting itself. Sometimes restarting quickly, sometimes after a few minutes (reaching Android). I tried to unlock the bootloader, by tapping 7 times on MIUI Version, enabling USB Debugging [I did not enable OEM unlocking unfortunately...] and run the flashtool. The flashtool reported that the phone was unlocked. And after restarting, the phone reports to be unlocked. ADB confirms this too. But after unlocking the phone, it never ever again reached to Android, restarting itself always after exactly 8-9 seconds. I can get into recovery mode and fastboot, but it will still restart. In Fastboot, my pc recognizes the phone as an Android Phone. Is there a magical way to get out of this loop?
Similar thing happened to twice. My power button was kinda stuck (not noticeable to eyes thoughts). Flicking onto the power button real hard solved the issue.

The problem persist when I completely remove the connector of the power/ volume button... When I push the power button I feel that the button moves and I hear a click-sound. Something else must be the cause of the problem. But still thanks for your help.
i have the same issue, did you find any solution to the problem?
Have the same problem is there any solution?
I don't have the phone so I cannot say this will solve the issue, however this sounds like a problem with the battery, something similar happened to my Redmi Go. The voltage should be low enough that the system boots, but just as it starts up the voltage drops to the point it reboots.
Solved it!!
I have Played with the power button and press it several times and it help.
I think the button was stuck or something close to that.
Thanks for you help guys!

Chance 1: Power button bug
Chance 2: EMMC failed and your phone is long gone.

Thank you! This was the issue. There is no way to tell that the power button is stuck. But it is and was causing my Poco F1 to bootloop even in fastboot or recovery mode. A symptom to look out for: your phone randomly locking once in a while due to this.

i booted in TWRP for 8-9 minutes with full brightness & no timeout but then mine didn't go into bootloop... recovery's getting powered but OS isnt?
Same thing happened to my F1, I press and flicked my power button hard and it worked. My problem happened maybe because the hard cover pushing the button too tight because it sometimes lock it self. Thank you for the tips! Just made account to reply to this thread.

Hello guys,
I've got a big problem with my I9300 and therefore I would like to ask here for any help. (If I'm in the wrong section, please move the thread to a correct one)
I had installed the Resurrection Remix ROM, v5.2.6. from 30.12.2014 and Googy-Max 2 recovery (CWM based) on my phone. I was using it for days and all worked fine.
One day I turned the phone off and I wanted to restart it. But it never restarted again; it ends up in a boot loop. It shows me the white Samsung Boot-Logo for some seconds, then a total black screen and the same thing repeats in a loop.
So I wanted to get into the recovery for wiping etc. but I couldn’t access the recovery. Nothing happens by pressing the relevant buttons. The device is still hanging in the boot loop. So I wanted to flash via Odin, but this isn't possible. I also can't go into the download mode. After pressing the relevant buttons, the green warning screen appears, which asks me if I really want to go to the download mode. But when I press volume up for "continue" or even if I don't press anything, the phone turns off and the boot loop with the white Samsung Logo starts again.
Therefore I ordered a USB JIG for forcing the device to go into download mode. When I plug the USB JIG in, the device actually goes into download mode but this status holds on only for a few seconds. After accessing download mode through the JIG, after a few seconds the phone turns off, restarts, (and because the JIG is still plugged in) the download mode appears again and it ends in a loop.
At first I thought maybe the power button is sticking and therefore the device turns on and off autonomous. But definitively I can negate it, because I opened the phone and removed the power button and nothing changed. Also by pressing the power button on the mainboard I can clearly hear the "click".
So I started a new attempt. Although the time, in which the device stays in download mode before turning off, is very short (only a few seconds), I tried flashing an other recovery, namely TWRP v2.8.3.0. So I prepared ODIN, plugged the JIG into the device, by appearing the download mode I switched cables and an other person clicked start at ODIN and it worked. So now TWRP is installed. Now I also can't get into recovery but after flashing TWRP there exist two little differences. First, after pressing the relevant buttons, TWRP appears for less than 1 second until the phone turns off. Secondly, when I plug the device in for charging, the Samsung charging logo appears for some seconds, then for less than 1 second appears a charging logo from Lollipop and the device ends up in a loop by displaying alternately the two different charging logos. Before flashing TWRP, the device booted in a boot loop (as I wrote above) by plugging it in for charging.
So the main question: how can I get my device work again
I tried telling you all details so that you have a better view of the problem.
Maybe I should flash a fully (stock) rom, but as I told you the download mode appears only for a few seconds. Flashing a recovery was possible, because the recovery file is very small - 7 MB. A full rom is much bigger and I think by flashing a complete rom, the device would turn off while Odin is flashing, therefore I ask first here for any assistance.
Thank you very much in advance!

Check and make sure that your volume buttons and home button are not stuck also. If they are not, I would suggest a visit to a repair shop as your EMMC chip might be weak already.

Your power button is failing, stuck in 'pressed' position. Try pressing repeatedly power button for several seconds, then release it completely. It shall bring it back to life. Visit your local service, or prepare tin, heat gun and soldering pistol. One button cost $0.2, they are selling them on eBay in sets of three (and 10, and 100....).
Happened to me some time ago, and video on youtube helped me to dismantle my phone, pull broken button out of it, and change it for new.
My phone was cycling like yours.

Thank you very much for helping! :good:
So the question is, whether it's the power button's or emmc's fault...
I did a little searching and found this video. I've got exactly the same problem like the guy. At 1:06 following the boot loop, at 1:34 following the problem with downlod mode.
Although he thinks it's caused to the sudden death problem, but at least in my case I think it's wrong because months ago I did the eMMC Brickbug Check.
Also I noticed a probably important detail. When I put the battery in the phone, it automatically turns on without pressing the power button like in 1:04-1:09 in the video. Which normal working phone turns itself on by simply putting in the battery...?
So it must get a command for turning on - (possibly through a defect power button?)
@Virnik0, do you remember, if you could hear the micro-switch clicking on your phone before replacing the button on the mainboard?

Your power button is faulty, replace it before you try fixing anything else.
Thank you very, very much for helping! :good: :good: :good:
Truly the power button was fault although you could hear clearly the "click".
I unsoldered and removed the power module and (by startig with JIG and rebooting via ADB) the phone works as it should. :victory:
Now I'm trying to solder a new power button......it's a bit tricky
Again, thank you very much guys!
I had the same problem, pressed the button many times, and it helped. Thank you for your suggestions
Recently my DNA has been getting laggy and restarting occasionally, and yesterday after sending a simple text message it decided to enter a reboot-loop that I think is probably fatal.
When I plug it in to any power, it turns on, shows the white/green HTC screen, and then immediately shuts down, and repeats the cycle. I have not been able to get it to turn off (while on power), and cannot turn it on (even into the loop) while off power. HOWEVER, I CAN use the vol - shortcut to get to the bootloader screen BUT I cannot select anything, as it immediately shuts down when I try to do something.
My DNA is running the latest stock software (OTA from Verizon, i think 4.4.2), and i have not modified it (S-ON, unrooted etc...).
Any and all help would be appreciated!
Bonus: on the 95% chance it is dead, should i go moto x/droid turbo or stick with a *gasp* iphone 5 for 2 months until gs6/htc m9?

I can not get it to receive any signals from me in the bootloader as it shuts down immediately. I tried connecting it to my computer for use with adb, but fastboot WAS enabled and developer tools were DISABLED (i think), plus it cannot keep a constant connection, so that wasn't working.
After doing some research I think I can save it IF I can get it to a stable state from the one it is currently in, and then using the bootloader screen to do a factory reset ( or use
"adb reboot recovery"), but like I said that is depenednet on getting it to stop the boot loop.
I also tried doing something called an RUU (I have limited knowledge of this, i sued the dottat one), but since it cannot establish a constant connection, it did not work.
Im open to any suggestions at this point! Thanks
I seem to have posted my reply in haste.
I have installed the "minimal adb and fastboot" tool that was suggested for basic fastboot use. Fastboot will not recognize it when I use "fastboot devices".
I did install the HTC drivers a while ago, but I suspect they may not work, could that be the issue? I am running win 8.1.
Thanks

Hold volume up and power until the screen flickers and immediately switch to volume down only. Get it right and you will land in boot loader. Need boot loader to show fastboot usb

Yes I have gotten into the bootloader before but as soon as it shows up (and i try to select using the vol +/-) it shuts down and restarts right away. Basically, I cant even get the bootloader in a stable state.

Fastboot usb is going to be your only option. If you aren't able to stay there it's hardware. Any chance a button is stuck?

You are right unfortunately, I can absolutley not stay in the bootloader with any sort of stability. I read on another thread that opening it up and disconnecting the battery from the motherboard would help, so thats what I did. As soon as I sealed it back up, the reboot-loop started right up again. My guess is that the motherboard is fried, its either that or the battery is holding no charge whatsoever.
If the board is fried, im done right?
if its the battery, is there any way to manually charge not going through the board?
Thanks for all your help btw!
So i was using RessurectionRemix (a version from last month) and recovery twrp 3.1.0-0 and the phone was working great!
Yesterday i left my phone charging over night and in the morning i wake up to my phone bootlooping!
So i tried different things including everything it says here https://forum.xda-developers.com/le-max-2/how-to/guide-hard-brick-fix-qualcomm-hs-usb-t3492949 without luck
I can get it into recovery and fastboot but as soon as i let the key combination go the phone stops and just shows a black screen (screen is on) and i cant get into qualcomm recovery to flash!
And the only way to shut off the phone is by holding power + vol up + vol down!
Any solution or suggestions?

connect phone to computer, try force shutdown phone by hard button, ater phone shutdown, immediately release power but keep both volume. Phone maybe will enter Qualcomm flash dead mode, and Flashone will regconize com phone (refresh nedded)
Hope you success ! And believe, if a phone can flash with Qfil or Flashone, almost that phone never die (software)
Are you able to connect to the phone via Vysor, either via Chrome browser or as a standalone app on Windows PC when you do not see anything on the phone screen? Please post if Vysor install goes thru successfully. Hope your developer options/USB debugging are on. I assume your phone boots but may have display issues either hw or sw.

Phone gets recognized but not long enough to do anything (windows makes sound but doesn't install anything and doesn't show up in device manager)
try this guide
https://www.gizmochina.com/2016/11/20/leeco-x820-max-2-super-unbrick-guide/
You have mentioned that you are able to see the device in recovery and fastboot till you release the buttons - does this mean if the buttons are held say in fastboot mode you are able to see the device via "fastboot devices" or in recovery the twrp screen or nothing ever shows up at all? Are the buttons clicking properly? Check individually to make sure - particularly the power button. Does it vibrate at any point of time when you press and hold the power button? Are you able to see any backlight when you say the screen is on?
If there no backlight shine a torch or sunlight from the side of the screen to see anything at all on the screen.
Vysor reports apk not installed when it attempts to download from PC to phone but fails. With Vysor you will have two windows one showing status of phone - this is the main window. The other is the mirrored one - that of the phone when you click view on the main window. I forgot that the phone requires approval to install the apk. Please see the attached thumbnails. Keep touching the screen about 3 cms up from the bottom of the screen (not the phone) to see any change. Hope your touch works.
I know it is quite frustrating to try a number of things. I recently went thru the same on Galaxy S4 to make sure the phone but for the screen works OK prior to ordering the screen. Besides in my case developer options was disabled and touch also did not work. It took about a week of learning and trying to see something on Vysor. I never have used a Sam phone till that time this broken phone was handed over to me.
After a lot of trying i found out that when i keep pressed power + vol down or vol up while connected to pc and device is off it gets recognized as
qualcomm hs-usb qdloader 9008 long as i keep the keys pressed so i tried the flashone method but it just says could not connect
Are Qualcomm drivers loaded on your computer? I have not used flashone. I used QPST to see if phone is connected. I am not sure if they are same.

You have mentioned that you are able to see the device in recovery and fastboot till you release the buttons - does this mean if the buttons are held say in fastboot mode you are able to see the device via "fastboot devices" or in recovery the twrp screen or nothing ever shows up at all? Are the buttons clicking properly? Check individually to make sure - particularly the power button. Does it vibrate at any point of time when you press and hold the power button? Are you able to see any backlight when you say the screen is on?
If there no backlight shine a torch or sunlight from the side of the screen to see anything at all on the screen.
Vysor reports apk not installed when it attempts to download from PC to phone but fails. With Vysor you will have two windows one showing status of phone - this is the main window. The other is the mirrored one - that of the phone when you click view on the main window. I forgot that the phone requires approval to install the apk. Please see the attached thumbnails. Keep touching the screen about 3 cms up from the bottom of the screen (not the phone) to see any change. Hope your touch works.
I know it is quite frustrating to try a number of things. I recently went thru the same on Galaxy S4 to make sure the phone but for the screen works OK prior to ordering the screen. Besides in my case developer options was disabled and touch also did not work. It took about a week of learning and trying to see something on Vysor. I never have used a Sam phone till that time this broken phone was handed over to me.

It doesn't stay long enough in recovery or fastboot to do anything it shuts off after a few seconds even with the buttons pressed after that it just shows a black screen
Phone vibrates when i press power and shows leeco logo (not os logo) and after 1-2 seconds screen goes black and phone vibrates again and shows leeco logo again and just continues looping
if i try to press power + vol up normally it goes into recovery but as soon as recovery is loaded screen goes black (screen on just doesn't show anything) the same goes for fastboot if i press power + vol down it loads fastboot but after 1-2 seconds screen goes black
if i keep pressing keys the phone just stays longer in recovery/fastboot but only 4-5 seconds
I assume you have adb and fastboot. Since you say the screen remains on when booting to recovery open a command prompt at the directory where adb is and issue a command "adb devices" without quotes. Does it just exit without showing any device or throws up some error? Try this irrespective of the black screen.
Have you looked at and tried what is given by @HTC-TYTN2 at post #8? It is for Le Max 2 and you will find a link to Quallcomm drivers too. Do not bother that the link mentions X820 even your Max 2 is 821, 829, etc.
since it happened after charging, you might want to check your cable and battery. best is to get a cheap usb multimeter.

I too thought it could be the battery based on that's the screen goes off. But he also mentioned that the screen remains on but nothing to be seen after a short while. Wanted to suggest slow speed charging probably via a laptop usb as I'm not sure if he used high speed charging resulting in battery issue.
Did you solve the problem?
My phone just died completely! No response at all anymore. I'm contacting the seller now to send the phone back.
Looks like it is a hardware defect! A pretty odd one but nothing i can do anymore. I send it back and post what the problem is as soon as get any information.
Thanks to everyone who tried to help!

Try this:
https://www.androidfilehost.com/?w=files&flid=136823
download file, unzip, open folder, connect phone to USB via fastboot ( phone off phone + hold volume -) . Click to the flash app in your PC. The app should find the phone. Confirm TWRP problem -NO and start flash.
Drivers must be installed.

Hey all
Bought this phone because it seemed great on paper.
Sadly I had very huge trouble getting twrp and root on it.
Tried the one post on xdevelpoers and got my phone finally bricked.
It starts up and resets all the time. It doesnt get past the "orange state, your device has been unlocked, please wait 5 seconds for boot"
It just crashes after 3 seconds and restarts all the time. Im unable to get into recovery or fastboot or anything.
This ****ing **** is driving me crazy. Ive never seen so many false information on the internet.
I had many phones bricked but still easy fixed. This is completly new for me and never happened before.

Thanks for your reply
If I try power button + volume up: Phone vibrates. Stays black for 3 seconds. Then (I think) it resets, vibrates again and simply tries to boot the phone.
After that the phone just resets after 3-5 seconds forever.
Before the bricking, this usualy lead me directly to a screen where I could choose recovery or fastbood mode.
Power button + volume down doesnt do anything I believe (neither did it before)
Alright I got something else now.
Read about some unbricking ways.
One suggested launching SP flash tool, clicking on auto format and starting it. Then plugging the phone in.
I did that. It said formatting success after like 3 seconds.
Now my phone doesnt boot at all. Its just black. Nothing happens when I power on. No vibration.
LED still shows when I try to charge. PC also now says unknown usb device or something detected.
Is it all over now lol?

I don't think so but a lot of devices In situations like this require either a unlocked bootloader and USB debugging. I will try to see if I can help you. I know if your frustrated. And this is not really my area but I try to help as many as possible

To be able to fully help you right, I would have to know your devices name or build number( example sm-a510f) and just possibly if you are able to access anything

How did you solve it, I have the same problem
Hello friends, I come to report here a problem I'm having with my device.
It is not charging my battery, I thought it was a problem in the battery itself, I made the replacement for an original, but the problem was not solved. the device uses all the battery power, it stays at 0% and it does not charge, besides, it recognizes my SIM card, but there is no signal from the operator to make calls or use the 4G network, I did a lot of research I saw that it was a problem related to Software, regarding the CQA test, I saw several tutorials, where none succeeded, lastly, I would like to install a custom rom to see if the problem would be solved, but I went to do the bootloader unlock process, but when Fastboot displays the code and I enter the site of the motorola, it returns me with an error that I can not unlock the bootloader of my cell phone, and I need to unlock to be able to customize the android.
follows a video showing what is happening with my device.

sorry if my text contains errors, I'm from Brazil and I used the translator to write
Thank you if anyone can help me because I have the device stopped because of this.
Thank you!
Hi, had the same issue. What helped me was connecting
power cable, going to bootloader, from there navigate to recovery. When it boots to recovery, regardless if there is any, leave it for some time. After about 5-10 minutes try rebooting, and it might picked up some charge, then it should charge as normally but very slowly, cellular connection also appeared.
Last time when my phone went to 0% and after going through this procedure my phone was at 17% after charging in recovery mode but didn't charge in normal mode after reboot. I also needed to toggle some setting regarding CQA in bootloader menu. Then everything went back to normal.
I will do this procedure to see if it solves my problem, remembering that my battery is in 0% and with it connected in the device it is only displaying the lightning, informing that the battery is without load.
what settings did you make regarding the CQA?

My device does not hold 5 seconds on bootloader because my battery is at 0% I believe the power supplied by the cable in the charger is not enough to keep it powered on. and now?
Original charger is definitely more than enough to keep phone on in bootloader mode. Try to make sure that usb C connection is dust and grease free.
Regarding CQA mode setting I can't remember exactly, but that is second thing.
Maybe even 5 seconds in bootloader should be just fine to navigate to recovery.
I wish you good luck, i was almost desperate when it firstly happened to me.
i had the same problem. after lot of trial and error i found a solution.
connect to power source (wall adaptor/modo battery mod.) get into bootloader menu and wait for 5 mins pressing vol up or down frequently.
then select reboot to recovery. on red triangle screen holding power button press and release volume up button one time. you will get into android stock recovery
select option wipe cache partition. and select yes when asked.
keep charging the device upto half hour in recovery mode and then select option reboot to bootloader.
after bootloader menu appears scroll down to BPTools and select it.
Your Phone will reboot and you will get Network and Your Phone will also charge normally.
Warning: Do not let your phone discharge to 0% or you might have to perform all above steps again.
This method worked for me as well. I recently replaced the battery on my Moto z force droid but couldn't get it to charge and signal was gone, after trying several things the Bp tools worked great, thanks dude.
