VW DELPHI MU9122D READ-ONLY FILE SYSTEM - Jester - 25-11-2023

HI guys , looking for  VW DELPHI dump file of 3Q0035864C 0842 851  MU9122D, in some reason i cant change any files by telnet. I read full dump, adopted to QNX and still cant change any files. First time i have problem with that version so didn't get any  dump backup b4.
Thanks in advance

btw, i try do some updates to 0867 or 0891 even try use that patch by C&D but radio after 2 restarts back to normal used mode and wont update.

This is strange. Have you tried to mount the files when the QNX is already up and running?

eMMC is bad. If replacing need to mind that for persistence area SLC is set.
Just writing some dump to some eMMC will end in a mess. MST2 delphi needs brain.exe

Known problem - I’m replacing eMMC if formatting and reflashing with working dump doesn’t help.

Just putting a dump on some eMMC is not enough. SLC area needs to be set for the mmc0t180 partition. There are only very few eMMCs supported that InstallationManager will set SLC area on successfully. Just writing a dump to eMMC without SLC set will cause a crash on next update and IM will attempt to set SLC area. If eMMC is not supported unit will be stuck in emergency trying to set SLC region forever....
Obviously all SWaPs and datasets are lost too when this happens.

@DukeFawks every service man has own ways to fix common problems - why U criticizing on my method? Every repair by me ends with full manually reflash of all files and devices works flawlessly wink
