Redmi 8a not opening - Xiaomi Redmi 8A Questions & Answers

hi guys,
I have a Redmi 8a (unlocked) after I unlocked and installed TWRP I tried to format it from TWRP and when it restarted it just stacks on the android logo and keeps restarting, even fastboot is not opening but when I try to open the recovery
TWRP doesn't open, the official recovery opens !!!!
and when I tried to connect the boot loader using the test point it connects put the problem that when I try to install the fastboot image using miflash it errors saying "error: only nop and sig tag can be received before authentication"
thanks:crying::crying:

There isn't any need to worry as long as fastboot is accessible and device unlocked, and there was no need to access edl via test points as fastboot allows you to access it via a command on an unlocked device, but that is not needed and also wouldn't be of any help
All you need to do is flash device via fastboot mode

thank you
i solved my problem.

My phone is breck (bootloop but can access fastboot)

So I tried to change the ROM of my phone because the vendor's one had malware but it was worse, my phone is stuck at boot screen and can't do anything with it.
First I tried to install a ROM with TWRP, it installed but it was just a black screen, you could only see the battery status.
Then I tried to install the global ROM that is on the official xiaomi site but it didn't work and it locked my phone.
Now I can't use TWRP, please help me. I am desperate.
Miflash isn't detecting the phone, but the PC does cause it listed under Android Phone->Android ADB Interface on device manager.

Once you rebooted it into download mode, use this:

My PC is no longer detecting the phone, only detects Qualcomm 9008
Ok, it is working till the miflash step it says "receiving hello packet" in red
You will need to flash a ROM using fastboot.
First install fastboot on your pc: http://www.theandroidsoul.com/how-to...t-setup-75174/
Second Download a flashable Rom: http://en.miui.com/a-234.html (make sure to choose the right one)
Unzip the rom and navigate to the 'images' folder
Put the phone into Fastboot mode (volume down and power button together until fastboot appears)
Connect the phone to pc with USB
Shift Right click on a blank space in the folder and choose 'open command window here'
run the following commands. one at a time
fastboot devices
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash cache cache.img
fastboot flash userdata userdata.img
fastboot flash system system.img
fastboot reboot

After that I use miflash?
Failed after second command
Hello guys, i have a redmi 3s china version, so i try to find global version, i installed all driver and try to use with miflash that:
land_global_images_V7.5.9.0.MALMIDE_20160805.0000.29_6.0_global_470b843c10.tgz
(if i use xiaomiflash i get error) meanwhile with miflash i see device and i flash it but something wrong , i restart the phone i stuck on the logo MI
I try also to download land_global_images_V7.5.4.0.MALMIDE_20160523.0000.23_6.0_global_dc5d804271.tar
seems is the right firmware
So i try again to flash in fastboot mode with miflash but i get error like i have no permission.
So i extract the whole firmware on a dir where there is ADB files , same problem...the device is locked
I try online the procedure with sms to unlock the bootloader ( i think is the only way, right?) or there are any other solution?
Maybe there is a stock rom to replace the original rom and put the global rom in another way?
Thanks in advanced
Bye

After you run 'fastboot devices' is anything listed? Usually a string of numbers. If not then the computer isn't seeing your device.
Try rebooting the computer, and trying different USB leads and ports if possible and try again.
Using this method you don't have to use MiFlash, and is for when MiFlash doesn't work.
Once your phone is working again you can try again to install another ROM using traditional methods.

Hello, i try the steps you give for EDL, after it the screen is not black but i see again the logo MI, i can go on fastboot mode but if i try to flash anykind of rom i get error "FAILED: remote: Critical partition flashing is not allowed)
other solution?
I think the only way is the unlock bootloader, but sincerally i dont know how it work. i did the steps online and the sim is on another device not xiaomi. I will get a sms from xiaomi with some kind of code? and after it how can use for bootloader?
There is another solution? I thinking....but why i cant use the original rom ?? always about the bootloader lock?

If you want phone encryption support, use TWRP 3.2.3-0, as it doesn't work properly in the following versions, namely 3.3.0-0 and 3.3.1-0.

Redmi Y3: Unable to boot System or Recovery with unlocked bootloader

Hey guys. I have a problem with my Xiaomi Redmi Y3. I didn't make any modifications to the system settings so I'm unable to activate USB debugging. One day, I am unable to boot to system, neither the stock recovery and the phone got bricked with a locked bootloader. The only thing I can access is the Fastboot mode. I can't even change it to edl mode. Also, I tried flashing the fastboot ROMs using the mi flash tool but that didn't work either. Could anybody suggest me what to do? I'm out of options... Thank You.

Hey there, I have found the solution to this problem. So anybody having this issue can follow this up.
The error occurs due to Windows (10) drivers incorrectly installed for the device. The solution is using a secondary phone via OTG with the app Bugjaeger (tutorials available on YouTube) to flash the TWRP image to your recovery partition. I searched this up but if no other way works for you (on PC), then you should definitely go for the provided solution.
THANKS!
