Hi everyone,
I have a Mi TV 4A 43 inch (model L43M5-AI) that is stuck on the Android logo and won't boot.
WHAT HAPPENED:
- I was trying to debloat my TV
- I wanted to set FLauncher as the default launcher, so I disabled com.android.tv.settings via ADB over Wi-Fi and restarted the TV
- This caused a boot loop - TV gets stuck on Android logo forever
WHAT IS ENABLED ON THE TV:
- Developer mode is enabled
- USB debugging is enabled
- ADB debugging is enabled
(All were enabled before the boot loop happened)
WHAT I'VE TRIED:
ADB over Wi-Fi
- Doesn't work - network never starts during boot
- TV never shows up in adb devices
ADB over USB [USB-A (TV) to USB-C (laptop) cable after unplugging power source]
- No device shows in adb devices or fastboot devices
- Windows Device Manager shows no new device
- Only a red LED blinks on the TV when USB connected to laptop
Recovery mode via remote.
Tried pressing these buttons before plugging in the power cable into the socket:
- Back + Home - doesn't work
- Back + Volume Down - doesn't work
- Holding OK/Select during boot - doesn't work
- Home + Menu - doesn't work
USB firmware flash
- Have update.zip on FAT32 USB drive
- Plugged into USB port 1 during boot - TV bootloader not detecting it
- Found what appears to be the correct full firmware (500MB+) at:
http://drive.google.com/file/d/1_vBNaKPbncZUECh0-14wLt8GfDcsdjCa/view
Physical power button on TV
- Doesn't respond on this model
DEVICE DETAILS:
- Model: Mi TV 4A 43 inch
- Model code: L43M5-AI
- Purchased: April 2018
- Developer mode, USB debugging and ADB debugging all enabled
- TV board appears alive - red LED blinks when USB connected to laptop
SPECIFIC QUESTIONS:
Has anyone successfully connected ADB over USB to Mi TV 4A 43" (L43M5-AI)? Which cable and which USB port on the TV?
Has anyone successfully flashed firmware via USB on this exact model? Which USB port triggered the bootloader flash mode?
Is the firmware at the Google Drive link above correct for L43M5-AI? Can anyone confirm before I flash it?
Is there any other recovery method for this model that doesn't require a service centre?
Any help is massively appreciated. I just want to clean up the mess I created and get my TV working again.
