How to edit MCU files ? - MTCD Android Head Units Q&A

I would like to find a way to edit these files.
I have a LM version and a XRC version I'd like to mash together if possible.?
The LM has "screen off" when you hit the screen icon with the small x but this one gives me the version unmatch error that I cant get rid of.
I'd like to add it to the XRC file, this one works great. I have the android unpack repack "pack" but its not workin for me..

Nobody found a solution to edit MTCD MCU files. If you find it please post it

Boost or increase speakers volume

Since updating to lollipop the general volume decreased and the speakers were not doing their job as in Kk. I could barely hear other People on a call. And used to get even worse if ambient acoustic was high. I rooted and installed recovery the flashed a rom based on MM beta. The general volume increased but not as I remember Back in kitkat. Any way to increase volume modifying some files or something? Flashable zip maybe? You name it.
Thanks in advance.
Cheers

You can use the mixer_paths.xml file from lollipop soundmods.
Extract the sound mod, find the mixer_paths.xml file and copy it to system/etc and set permissions to r-w-r-r and reboot.

Thats why i said dont flash the zip, you have to reflash your ROM or restore a backup. Read my posts before you try again.

Ok, you must not have set the permissions. In your file manager (I use Es file Explorer) hold down on mixer_paths.xml, once it is selected, go to properties, then select permissions. You must set permissions to r-w-r-r.

I have an UB, but that shouldnt make a difference, you could unzip the rom and copy the original mixer_paths.xml to save reflashing.

Try this one, I might have linked you to the wrong sound mod.
That is the exact file I copied to my system/etc.
Good luck.

just replaced the file you uploaded to MEGA, gave permissions as usual, no luck. :/
I've been tempted to downgrade back to 4.4.4 nad keep high volume back to normal values. This is crazy, volume in lollipop and MM roms in certain way are basicaly the same. Can't hear a call form the distance as good as KK FW. Any other solution for this issue? Thanks for your kind cooperation.

if you swap out or overwrite your original mixer path XML with one from a sound mod that has louder volume one. flash it or unzip it and take the mixer path XML don't downgrade that's ridiculous. Its really really easy where are you having problems.

PX5 has the 8-core rx3688, right? 2gb ram, android 6?
maybe that's the reason it fails...
Could someone please post the stock radio apk from stock 5.1.1 rom? Thanks in advance.

Update: they work. Radio app which i was interested in, has issues (no station find on scan), but music app work ok. Up to your taste which is better.
Edit: app can't be controlled via steering wheel buttons, so back to original for me..

I think the point he was making is that there are 2 root methods (2 different programs, if you like):
1 is called KingRoot and doesn't work
The other is called KingOroot, and this is the one that has shown to work on these units.
He wasn't pointing out your spelling mistake!
Jeah i know, but i tried Kingoroot and it does not work. I havent tried KingRoot yet.
Try this

You must install and then run Kingoroot. At 90%, it usually hangs, then simply terminate and re-run. It takes a while to get the root done.

Both apps doesnt work.
Toast message after 10 seks appear: "Root fail"
But thx for help.
I read about a method to enter the stock recovery via an update.zip.
So you are able to flash supersu.zip through stock recovery.
Anyone got an update.zip which is compatible with my device?

I think the only method to root could be by means of adb from computer and inject the supersu

In factory settings type 'adbon' and then 'adbwf' and that enables adb wifi.
That gets me into the unit and I've then pushed su, and apk to data/local/tmp but I'm too thick to go further!
Pushing the intel sofia adbwifi package kills my HU completely, lot of hunting to find 7.1.2 20170731 to flash back!
Using 'RK3xxx Firmware Tools by SergioPoverony' allowed me to turn 'ro.secure' to 0 in the boot.img, repack nupdate.img and boot normally.
If I unpack 'system' and straight repack back, the unit will not even come up with the boot logo.
I think we need a pure 'root 7.1.1 - 7.1.2 PX3' thread that remains purely on that topic! There are bits and bobs dotted over XDA and 4RU but nothing concise. There must be a way to get root just so I can disable all the apps I don't use.
adbwf doesn't work for me.

Your welcome. Great idea.
Does anyone have a solution in the meantime for the root problem. I would like to bring TomTom to run on my new HU.
I really need to root my mtcd device, hope somebody finds out how to do it :good:
Well I've got as far as SuperSU just failing to update the binary.... hopefully getting there. But it is through and wifi. I have no idea how to go about it without.

About newer MTCE firmware versions to flash

Hello, everybody,
I have a couple of doubts that for more than I have searched, both in google and forums, I have not been able to find out.
Recently I bought an Isudar Head Unit (this -> https://es.aliexpress.com/item/Android-7-1-1-Two-Din-7-Inch-Car-DVD-Player-For-FORD-Focus-S-MAX/32808228875.html?spm=a2g0s.9042311.0.0.3da263c0xgGxNv) which had installed the MCU with version "MTCE_GS_3.01_3" and I installed the version "MTCE_GS_3.07". On the other hand I had installed the Android compilation "PX30 8.1.0 OPM8.181105.002 eng.htc.20181224.174229".
My question is, which Android update can I install from here https://yadi.sk/d/umCvHqCDzHccr/RockChip%20PX30%20%20Android%208.1 ? I thought I understood that I can install any of them. Is that right?
Can I also install the existing version of Android 9 (https://yadi.sk/d/umCvHqCDzHccr/RockChip%20PX30%20%20Android%209) ?
Thank you very much in advance
In view of that you have a PX30 with MTCE_GS it should be possible to install your stated Android 8 roms for GS.
Android 9 should go too.
All at your own risk!!!

Sure i think too you can install every rom but maybe there are different options in the setting of each rom. There only helps try out but you can flash back if there are some faults.
Wich Android 9 you want install? Stock or custom?

I'm very lazy and I haven't tried to root the unit yet
but if I could flash a newer 8.1 stock rom, although from a diferent manufacturer (my unit is GS, and I flash a HXD one)
So I have been able to verify that although the MCU always has to be from the same manufacturer, the Android seems not to be necessary.

I just had to rename the file to update.zip on the HA file after I extracted, in case anyone else asks. I also have to figure out how to root mine as well, so if anyone has info for that I'd be interested....
Sent from my SM-G955U using Tapatalk
I found a possible root method. I would have to write the code into the update.zip and repack it then flash again. Even if that does gain root access, that still doesn't solve a custom recovery so I can flash zip files like magisk and Xposed.

One question, what was the original name of the file? Because I'm pretty sure isn't a name problem, because the recovery recognoice it well and try to flash it. But the problem is that the recovery can't open the file, so, as I said before, I think that your file is corrupted

Hi,
Did you manage to get Android 9 working on your PX30 unit? I have tried several times with different versions (GS, HA, LM, etc) but keep on getting the same error like you did.
Any suggestions will be appreciated.
