Hey everyone, I am following this interesting thread as I am interested in updating my standard MIB2 as I have installed a new 8" glass screen with "APP" , button but it is not working.
Here are the details of my current software:
3Q0035824A (MIB 2 STD Composition Media)
MST2_EU_VW_P0231D_MU0633
I have never patched the unit, it is original. I already own Android Auto and my goal is just to be able to activate the "APP" button.
The target firmware I thought is MST2_EU_VW_P0631D_MU0753 it's correct?
I would like to understand the procedure to follow to perform this upgrade, and in addition to know if all the OEM activations will remain (such as AndroidAuto and CarPlay for example)
Thanks everyone in advance
I try to reply myself.
If i understand correctly i have to do:
- enable green menù with vcds
- from green menù enable ethernet
- connect through Putty and save InstallationManager with command:
- Mount SD card
cd / && mount -uw /sdc1/
- Create backup folder on the SD card
mkdir /sdc1/backup/
- Secure installation manager
cp -Vf /ffs/sbin/InstallationManager /sdc1/backup/InstallationManager
- after find the correct Variant number from metainfo2.txt of MIB2STD in the zip of New firmware that i want to update, in my case MU0753 have Variant 17256
- Open InstallationManager file with HxD
- Find every-where 17248 (Variant of firmware MU0633) and replace with new variant 17256
- save the modified InstallationManager file
- copy back to the MIB with command:
cp -Vf /sdc1/backup/InstallationManager /ffs/sbin/InstallationManager
- format SD card and put in the root the new firmware MU0753
- start update procedure with manual SWDL in Green Menu (when update start choose "select all")
with this procedure i can make the "jump" of version but maintain all my OEM activation ecc...
It's correct?
thanks for help
