[Android Head-Units] radinix:
I bricked my unit.

I can't remember exactly what firmware did it, a lot of stuff has happened since first attempt to update firmware.

What I can give you is a very basic overview of how I fixed it.

=======================================

Flash Computer package gongban_YT5760L_ui1-1024x768_zlink-v1.68.zip - make sure to select correct size preloader file. eg, 1,2,4

Put 2 files on FAT32 USB stick and

XYAUTO_UPDATE.bin

upgrade ota gongban_YT57xx_1280x800-v1.73.7_a31d36be_ota.tar.gz

Insert USB into stereo. Wait while it reboots twice then remove USB when screen is readable.

Navigate to Settings > Factory settings > Touch settings > Key position. Select "no key"

Touch now matches screen

Navigate to Settings > Other settings > ScreenRotation. Enable. Password 8888

Screen up right way

Write IMEI with Maui META

Find an apk download of google services. I used ver 23.17.15 just because it's what I found and it worked. Without this Android can't update itself.

=======================================
[Android Head-Units] apaicello:
Can you share the file in another cloud?
[Android Head-Units] radinix:
No. Just use their file if you want it.

[Touch Diamond, MDA Compact IV General] logger:
Mate, I have had my Diamond for several months. Tried everything available to fix this with no luck. I think it is somewhat ROM dependent too. Tweaks will work with one ROM and not another. Or will work for a while then stop working. I have begrudgingly learnt to live with it.

[Treble-Enabled Device Development A/AB ROMS] gabriel.oliveira.brito:
Hey guys.

On my old SM-J730G device, some ROMs did not have the confirmation dialog for ADB certificates. This prevented me from connecting to the shell, getting logcat output, etc.

To resolve, I needed to copy the certificate to the device, install a root file manager, and copy the file to / data / misc / adb / adb_keys.

Well, I developed an application that helps in this process. Your requirements are only to have the device rooted and to have copied the adbkey.pub file to the device. The app will assist in the implementation of the same.

About restoring SPL, you have the needed info in the HardSPL thread http://xdaforums.com/showthread.php?t=410150, for now there are only one SPL, version 1.90, so the follow the steps and you'll get the stock SPL.

UK MDA Vario IV ROM

Well, being sick of waiting for someone to do so, I finally followed the procedure to reconstruct the UK MDA Vario IV ROM.

The ROM version of my phone is 1.69.110.8 WWE (08/21/08) but I have not tested the resulted file yet.

I am curious about the version of the BaseROM having anything to do with the result, since it has a numeric advantage (1.90.405.1) over the ROM reconstructed.

Please, whoever wants to download it, feedback.

Also, I do not have a rapidshare account, and the file will not last for long (10 downloads) whoever has the means and the will, feel free to reupload it.

But that comes second.

Feedback is crucial.
