Bricked Mi 9? - Xiaomi Mi 9 Questions & Answers

While trying to install a custom ROM I wiped the system and vendor folders and formatted the phone. I was struggling to push the rom via ADB as it kept giving me errors then eventually the battery died.
After the battery died it does not go on. I charged it for a few hours and when I put it on I only see boot screen for a second and then an empty battery symbol and then it goes off.
I'm assuming that certain files to keep it awake or boot was deleted. Is there anyway to revive it?

Xperia Z Boot problem

Hello, this is my first post here and ofcourse I have a problem...
So yesterday I was rooting my Xperia Z, unlocked the debug mode and was able to access the recovery mode a few times. So I flashed my device to 4.2 version with a computer then I copied the 4.2.2 .tft file and the Kernel into my phones internal memory, turned my phone off, turned it on again, turned on the recovery mode, did the "Wipe data/Factory reset", wiped the catche partition, wiped the Dalvik cache, formated the system, formated the data and the cache. So then I went to install the prerooted ROM but my phoned seemed not to find it in the internam memory so I selected to reboot my device and since then it is acting all weird...
So the phone then tried to reboot but freezed at the Sony logo, the battery was about 89% and the phone started heating like it was working on its max, the phones battery died after about 2 or 3 hours, so ofcourse I tried connecting it to my PC to try to charge it but it just started to boot loop, I could hear the computer making a notification sound that the device is connected and after a few seconts it just disconnects. It seems that the phone isnt charging at all because after leaving the phone to charge for the whole night with a regular charger the phones LED was still red and was giving me 3 blinks when I tried to turn the device on. I think that if I could to access the recovery mode again I would be able to fix everything from there on my own...
Any help to fix this problem is welcome, I can provide more information about the problem if there are some questions
P.S. I already tried to remove the microSIM and microSD cards

I noticed a really weird thing. It looks like it might be both technical and software problem. So earlyer I had the rooted 4.4.2 version but it started to bootloop when I turned on the camera, the device turned off when it was at about 60% battery. So I though to hell with this version and wiped everything again, installed the 4.4 version with flashtool but then the bootlooping started again, it went no further than the Sony logo, after about 2 hours of trying to get the damn thing on I took my fathers Galaxy S4 charger and pluged it into my phone, for my surprise the phone started charging and was displaying that battery icon in the middle of the screen, so now its about at 30% battery and trying to turn it on wont work, almost gets to the main screen and then instantly turns off. Ill try to charge it to about 80% battery and then try to turn it on. I suspect that the device thinks its battery is empty when it is actually at about 60%

[HELP] Redmi 4x won't boot.

Hello,
my Redmi 4x won't boot. I tried to find some solution for this issue, but I can't find it anywhere, so I created this new thread to ask you for your help.
Last night I was out in the city and my phone died because of low battery, so after I came home I just wanted to charge it as usual. Battery logo showed up and it was behaving as always, but when I tried to turn it on it couldn't boot again.
After pressing the power button the splash screen flashes for a brief moment and then it just turn off again. This happens all the time from the moment my phone died. I'm not sure what went wrong here. I can't get it to recovery mode either. So I wanted to do a fresh start and flash it again with new ROM here (Ressurection Remix 6 is what I have now)
I'm able to get it on fastboot mode, but once I try to flash it with MiFlash I get error message like "error:FAILED (remote: Critical partition flashing is not allowed)"
So I looked up for a solution and I found that I need to get it in EDL mode with adb.exe
I tried this solution but with no luck. Phone is restarting but it won't turn on again and the fastboot mode is lost.
I'm not really sure if I have right drivers for it. Qualcomm HS-USB Diagnostics 900E is what I have now. I can't also change the usb debugging mode obviously, so I'm also trying to find some solution for this issue either (is there any chance how to turn it on with adb.exe?)
I think it's softbricked but i'm not really sure.
Thank you for your help

Hi, most likely your battery is faulty. Current draw during Android kernel boot up phase is above 1A whereas only around 0.2A for a working OS, that's why neither OS nor recovery can start when the battery develops high ESR (internal resistance). Do the following test:
fully recharge the battery
do not disconnect the charger
turn it on
Your Android may now actually work again but you must use a short quality cable connected to a 2A+ charger, which will support the battery at boot time - and you can disconnect it later.

Thank you, but the battery wasn't the main issue, because once I was able to flash it through EDL mode to the latest stable official ROM, the battery was on 93% already.
Now I'm stuck with MI logo and powered by android with 3 blinking dots above. I watched somewhere, that it could last for 7 minutes, but for me even the 15 minutes is not enough, so I guess i'm in bootloop.
For some reason my bootloader is locked again, even though I already made the unlocking process earlier before I flashed to Resurection remix 6. My phone doesn't even appear in device manager. I can't even use it as a storage, so I could try to flash it to custom ROM.
I'm not really sure wat happened and how is it possible to brick your phone by just draining your battery to 0%
Ok, phone is alive again. It booted up right after I inersted microSD card in slot. I didn't know this was necessary...

Mi8 not charge

Hello everyone,
I've got a problem with my Mi 8. When I charged battery to 100% then I remove cable from my phone and use it until battery 30%.
So I've to charged again but nothing happened.. it's not charging until I restart the phone, it's will charging again.. and If I want to charge my Mi 8 I must restart once before charge it.
How to solve it and what happened with my phone?
Thanks.
PS. I already update the global rom latest version
Hello i had the same problem, i installed new ROM (factory reset) and this fixed the problem, seems something gets stuck. Got mad that i had to reboot everytime when i wanted to charge phone.
At the beginning everything was stock. After the problem occured i unlocked BL flashed TWRP and then a ROM from mi-globe. This fixed problem for me, since then i never had it again.
Probably batterystats file was broken. Try deleting it. It'll be recreated at 100% charge or at reboot. You can do this on twrp or with different apps.
I agree with @The War Profiteer
Boot to recovery, and use recovery file manager to navigate to Data/system and then scroll down past the folders and delete batterystats.bin file then reboot. Alternately if you have root you can install this app "Battery Calibration" to calibrate your battery.
Afterwards charge your phone to 100%.

Question Redmi Note 10 Pro stuck in a boot loop

Today I left my phone in a cab and got it back in the evening. But after I got my phone it was stuck in a boot loop (after force restart - power button press and hold - it will go to battery icon and automatically restart after a few minutes and again goes to battery icon). Please see the video to understand the boot loop. Unfortunately, Developer options of the phone were not enabled.
Can boot to recovery but can boot to fastboot.
Can you please help me to boot my phone back to normal or sideload a ROM via adb.

Was able to fix the issue. Followed below steps,
1. Kept phone until the battery fully drains
2. Plugged into the charger and charged the phone up to around 65% while the phone is switched off.
3. Switched on the phone when the cable is disconnected.
4. This time the phone was booted to recovery. No battery logo anymore
5. From recovery, rebooted the phone. But again it was booted to recovery.
6. Wiped all data and rebooted.
7. Phone was booted to MIUI os but had to set up the phone again from the beginning.

Same problem bro, did u resolve it???
I think your battery is empty. Leave it on power for a while and check if its charging. Maybe the charginglevel is too low for booting up.

I hope it was that simple ..it seems probably like a bad update. My gfs phone did the similar today
The digitizer stopped working, I force reset the phone and boom ..recovery mode - Trying everything but it doesn't work. Wipe surely would work but she has pictures and videos so I'm trying to avoid that. Plug it to charging but she remembers it had like 75% of battery ...geez (hoping for a miracle)
EDIT: Probably this happen from the bad xiaomi update, anyway I did wipe the data and as expected it work without an issue, I'll unlock this phone and ditch MIUI (I mean I did it to my phone Xiaomi Mi Mix 2S from day 1 - I hate miui) ..now my gf has a reason to hate it too
A factory reset could be painful, since you would lose everything on the device. I saw a guy tap all over the back of the phone with two fingers, and boom! The Redmi Note 10 Pro boot normally! I tried it on a friend's phone, and it worked.
Hello,I had a kind of a similar thing.
I left my phone to charge and when I was back it seems to be stuck in a boot loop(MIUI14)
Well,I tried to force restart but the same.
Before I go to recovery mode,accidently,I putted the phone in fastboot mode.I restarted it in the try to go to recovery mode but the phone started normally.After boot,it's shows an update compete message,so te problem was from an android security path update whatever.

I have important apps on the phone and I wasnt thinking about a factory reset anyway but hopefully it worked in that way
