MHI2 a6 c7 bricked after patch

[Oski]

Hi. I have a problem with mib2 out of a6 c7. I did firmware update from p3634 to k3663, then patched it, and all seemed to be fine. Then I tried to code it with vcp, but it froze during coding. So I tried to code it once more - but unit was not responding. I reset mib just to see a blank screen for over a minute, then I showed "radio initializing" and it stuck. I could not connect to it with vcp, with putty I can only connect on mmx, rcc doesn't respond. I thought I could restore backup I did, but when I go for "on -f rcc flash it -v -a 0x00540000 -d -f /net/mmx/fs/sda0/original-ifs-root-both.ifs" putty says "rcc: host is down". Same result when I try to manualy change dir to /net/rcc. How to recover it? Now, I can do it on bench only, as I removed it from the car.

I can fix your unit but not remote.

p.s. Keep using the "free" solutions ... more will come.

I have it on quadlock, rcc responds, however only on ipl mode, without shorting tx and ground is dead. Breaks fine but after 10 seconds runs further. Can you help? Here's the log.
