Same for ALP-L09C432B148-SP1
I would advice to not install BLA-L29C432B147.
It has the same XLOADER changes as the other ones for C636 that bricks your device if you update/downgrade/rebrand from the affected firmware.
Meaning you won't brick if you install B147, but will (most likely) when you update/downgrade/rebrand from it.
It's confirmed that you can go 02 XLOADER to 02 XLOADER (C432B147 and the new C432B146 use 02 XLOADER), but not back (B145 uses 01 XLOADER).
So no more downgrading to a 01 XLOADER.
XLOADER checking tool:
Here's a tool to check XLOADER 01 or 02. You can use it to check xloader of any firmware, Mate 10/Pro. It should work for other models too that has 01/02 on those offsets but for Mate 9 it has 00.
Extract, put update.zip in 'check' folder, run check.bat. Wait for output.
Using FullOTA Update.zip takes a while as it has to extract the full update.app.
If it reports errors make sure the path to the script is not over 200 characters and that it doesn't contain spaces. Best is to extract directly to C:
If you are rooted can also dump your own xloader if you want to see what you're currently on.
Download Terminal Emulator from the play store and open it
Type the following
su dd if=/dev/block/sda of=/sdcard/xloader.img
The first affected offset is at 1A8, its either 01 or 02.
Using Mankindtws HWOTA cygwin folder/repack script as base.

Using Perl2exe so you don't have to install perl.
