Battery change on Lenovo

Linus67

I plan to flash a Lenovo Tab M10 HD 2nd Gen LTE 4G/64GB (X306X) with Ubuntu Touch in the next few days.
Later on, I might replace the battery with a new one.
Could there be any issues with replacing the battery while running the Ubuntu Touch OS? Or should I replace the battery while it’s still running stock Android 11?

No.
The only issue with replacing batteries on devices like that is opening the device and reaching the battery.

I now have a different problem. I can’t get Stock Android 11 to install on the tablet.

The spflash tool gives me the following message:

smart phone flash tool error: status_brom_cmd_send_da_fail (oxc0060003)

@Linus67 is it already running Android 11? If not and you are using Windows, the Lenovo Software fix tool is easier...

@MrT10001 Getting stock Android 11 onto the Lenovo Tab was a real challenge yesterday.

Problems:

SPflashtool failed due to chip permissions.
Attempts using MTK bypass tools also failed

How it filaly worked (after ~3 houres)

Download Lenovo Software Fix Tool (thanks for the tip)
Create a Lenovo account (using a disposable email address)
Start the recovery workaround (but you can only flash up to Android 10 !!!!)
OK, perform a recovery with Android 10
The recovery tool downloads the ROM (A 11) to your PC
Before starting the recovery, you must replace the downloaded Android 10 files with the Android 11 files witch you downloaded from the UBports link bevor.
Then start the recovery process and the Lenovo Software Fix Tool will flash the tablet with Android 11, which you’ve placed in its nest, just like a cuckoo’s egg.
