[MTCD Software Development] JoaWah:
The steps I took after I bricked my (KGL) radio:

Bricked totaly, only black sreen, no recovery mode, complete empty and black (in total four times)

First an sd-card fully formatted (out of 5 SD cards only one worked to boot!!!).

I modified the bootdisk.

I used this as a basis: https://xdaforums.com/showpost.php?p=75664396&postcount=3254

But now it's coming!!!!

After using SD creator, where it says in the manual that the file update.img should be replaced by the update.img from the folder, I didn't do that :silly: .

I took another update.img from android 6.1 and replaced it on the SD card. I used the latest Android 6.1 created for the KGL: https://yadi.sk/d/umCvHqCDzHccr/RockChip PX5 Android 6.1/KGL/update

This was the only one I got started after the crash.

Android 6.1 worked again, from there I updated to Android 8 v3.5 version of Malaysk (from this threat).

Again the same problem, the Malaysk version bricked my radio.

I adapted my idea of the SD Bootdisk to get into the recovery of V8. I used the Bootdisk from Malaysk again, this time I didn't change it.

This one from V3.5: https://xdaforums.com/android-auto/...-malaysk-roms-px5-2-4-gb-8-0-android-t3762724

After ejecting theSD card, I got into recovery.

From here on I did it differently. I have the Android 8 from KGL i used the GPS card slot (USB didn't work, I couldn't get it started from recovery)

Version KGL: https://yadi.sk/d/umCvHqCDzHccr/RockChip PX5 Android 8.0/KGL

AND BANG... ANDROID 8 WORKS! 3x cheers, party and beer.

But now I wanted more ...uuuhhhhh no, not more beer, but Android 9.

From this I made my bootdisk: https://xdaforums.com/showpost.php?p=80034820&postcount=33

Once in the recovery mode of V9 I installed the Witson version, via the sd-card from the SD-card slot and it works since yesterday evening (27-8-19).

But this time everything without bricking :victory:

Two weeks and a lot of (verrrrryyy much) time spending on the problems, and a lot more gray hair. A lot of times i wanted to fix it with a big hammer, but i didn't. Totally it bricked 4 times. It was a hell to get it rebooted, sometimes 2 hours constant attempting to get it one time to reboot.

And now why I'm going to sell my HU. My PX5 was bricked and did't do anything for almost 2 weeks, driving in a car without radio makes me :mad:.

I'd seen and read about the PX6 before, I like to work with new gadgets (but the money :eek: oops) so i only look at Ali but dit not buy it.

After I had crashed my PX5 and hadn't had a radio for a week and I got the tip from Marchnz to flash the SOM, I had something like this ... HELP!!!! this is very difficult!

That same evening I ordered the PX6 with DSP from Ali Sadocom. After i ordered the PX6 (maybe to fast/early) i started fighting against the PX5 machine :mad: and after again three full days i found a way to get it un-bricked. Then again it took three day's (6 or more hours each day) to install A9.

But there is only one radio fitting in my dashboard, so my PX5 will go on sale as soon as the PX6 works perfectly.

I can't put the PX5 in a closet, I think that's a shame after so much work.

Now that it's doing so well someone else can enjoy it with the for now newest Android 9.

And for me, after selling my "old" PX5 the new PX6 will be less painful in my purse.:cool:

At "marktplaats dot nl" and at "e bay klein anzeigen" they are sold for a nice price.

So thats why i'm gonna sell it.
