psyched[/SIZE]]Hi rooter,
at first I have to say that your postings on TMC are very interesting for me, thanks for sharing you knowledge.
As far as I can remember you've been the first one sharing real informations than just small bits - and it seems you're the first one and also the last one because most the other 'specialists'(in hiding informations) disappeared.
At the moment I'm working on a MCU1 that I've purchased just for bench. But how life goes the emmc from my own car also wrecked last week.
With the bench MCU I'm starting with an empty image because I don't care about keys&certs, just firmware (2019.20.4.2) on p1/p2 and empty p3/p4.(I could dd/ddrescue the old emmc without errors but it's not readable, fsck and gparted data rescue couldn't help - I only can mount p1 and see directory strucure and files but no information inside.)
I also want to obtain root and I really have read your 'manual' several times but I've still some questions.
- according to the situation that I'm starting with empty p3/p4 directory/file structure is created on first boot as I've heard - so I'm not able to find the files you've described in your step-by-step instructions.
- since 2019.4.x tesla is mounting a tpmfs over cron - what's the best workover for this issue?
I always try to find as much as possible informations on my own - before questioning. But I don't want to make to much try and error especially when it leads to resoldering the new emmc on tegra board
