Stuck at boot screen after trying to restart my device, don't want to lose data

[Prakharpathak]

Hey there, so I was playing a game PubG in which in the middle of a match the screen got stuck. I waited for 10 mins for it to go back and tried locking the screen with power button but nothing happened. When I long pressed it closed for a second then restarted and got stuck on bootscreen with only mi logo and no animation. Now it isn't switching off it gets rebooted to the same screen again. Only fastboot is opening. I don't want to lose my personal data there photos, videos that includes all my college life. If I try to flash it I think I will lose all data. Also I didnt backup all the data on mi cloud or anywhere. Please help me.
Also in flashing if I select the option 'save user data' will my data be saved?

Is your bootloader unlocked?
If you only want to back up your music, photos,videos,documents etc. , flash twrp recovery then boot into it (power+vol up about 11s). Connect your phone to PC. Then copy all data you need to save. Then reboot to fastboot and do a clean flash (clean all).
If you either want to back up the application data, do the previous operation without flashing first, and then do a "dirty" flash (save user data). At this time, your phone should be able to boot, use the BACKUP app to back up all your application data and copy it to your computer. The backup file seems to be stored in /storage/emulated/ 0/MIUI/backup, I don't remember it well.
After backing up all data you needed to save, you'd better do a clean flash using fastboot method. Make sure you choose "clean all".

Thanks for replyling. I think my bootloader is not unlocked. Also power+vol up is not working, only power+vol down is working. Can I flash twrp with bootloader locked?

So what did you do? Please tell me the method if you were able to solve it.

Re: Prakharpathak

I'm sorry because I can't save a phone that have a locked bootloader. If you wish to try Qualcomm QDLoader9008, maybe it will not work. Xiaomi has locked the 9008 port for their phones. Unless you have an authorized Mi account to get the verify token and send the authentitation tag to your phone, or the phone will reject all flashing commands. QPST is not working. The only difference is that the bootloader can be unlocked, but the 9008 requires authorization every time.
If you want to try the force unlock bootloader tool, once the force unlock is successful, you will lose all your data. Unless you can erase the recovery partition before the bootloader send a wipe command to Mi-recovery. In other words, if the recovery partition is erased or the recovery is not stock recovery (like twrp, etc) , unlocking the bootoader will not lose any data. Twrp does not accept the wipe command from the bootloader.

Re: @jagannath287

If this is also useful for you @Prakharpathak , you can also try.
If you are ready to lose all your data, you can try to use Mi PC Suite. Offical link of MI PC SUITE:
http://pcsuite.mi.com
You must be able to boot into Mi-Recovery, otherwise my solution will not help you.
Download the recovery ROM for your phone. Note that you can't upgrade or downgrade the OS version using this method.
After downloading and installing the Mi PC Assistant application on your computer, run it and login to your MI account. Then select FLASH ROM section and connect your device to your PC. Make sure your device is booted into Mi-recovery and selected “Connect with MiAssistant”.
Warning: you can't downgrade/change ROM region (you can only install the same area version to your phone, like MI-MI, RU-RU, EEA-EEA, etc) using this method.
Make a full wipe for your phone and select the RECOVERY ROM package: fast update and agree with full wipe. Then wait for the data erasing is fully done. After you see “Checking zip file update” and if all ok, the flashing progress will start and you will see the flashing is in progress. At last, you will see the window with successfully flashing. In theory, the phone will reboot to system automatically. The first start will take about 10 minutes. Be patient and wait the welcome screen.
There is another MI PC SUITE version that I found and I attach with my post. There is also a XiaomiADB flashing program.

Alternative method:
Download the adb driver and install it on your computer. Use the XiaomiADB full-auto flash program to flash your phone.
Select “Connect with MIAssistant” in the recovery and connect the phone to PC.
Make sure the recovery ROM zip file and XiaomiADB flashing program that in same folder. For start flashing just HOLD zip ROM AND DRUG IT TO THE XiaomiADB. After this command your DATA will be reset! You lost all files and Settings on your device.


At last, I suggest you to unlock the bootloader for your phone as soon as possible and flash your phone using MiFlash in fastboot mode in order to avoid facing mysterious bugs. A phone that have an unlocked bootloader is easy to save (unbrick) or backup all data from the phone without booting into system.

Re: @Arun pm

Xiaomi has locked the 9008 port for their devices.
Can you flash and boot into TWRP recovery?
Can your phone boots into fastboot?
Did you try to flash every partition manually?
Did you try to flash the oldest version--V9.5.19?
More information needed. It can save time and guesswork.

Re: @Arun pm

You'd better create a new thread otherwise we will disturb the original author of this thread (Prakharpathak).

Did you mean the returned message from your phone is like this:

Sending "recovery"...
OKAY. Total time: 4.016s
Writing "recovery"...
FAILED<remote: Permission Error>
finished. Total time: 4.016s

In theory, the fastboot won't return this message and the USB debugging switch has no relation with fastboot flashing.
All partitions can't be flashed and return the "permission error" message?
Can you take a photo of the flashing error message?

I am currently facing a similar situation.
My device redmi note 5 pro was running on miui 11 and suddenly its screen froze and then it got restarted and stuck at mi logo. It has locked bootloader and I can't access the stock recovery but I can access fastboot mode. I tried flashing different miui versions with different flash tools and everytime the process starts then after 9 seconds I get the error "ack count doesn't match". I tried flashing with edl point method as well and with a patched firehose file to bypass mi authentication but still got the same error. Can you please help me? I searched around the net and I can't find anything related to this particular error I am getting. I would really appreciate if you can help.
