In the first post rom 7.1.2 the process is written:

[ROM][PX3][RK3188][Nougat][7.1.2] Hal9k ROM 2 for ALL RK3188/PX3 MTCD/E head units

Hal9k Mod v2.507.04.2019 Firmware for platform MTCD-MTCE Rockchip PX3-RK3188 1024x600 800x480 based on the latest official version of HCT2. This is the further development of my Mod v1.x based on Android 5. Thanks graviton.no for the equipment...

xdaforums.com

I imagine it is the same process for 5.1.1.

One doubt: the stick usb is also prepared by SD_Firmware_Tool or only contains the nupdate.img?

thank you so much
[MTCD Software Development] typos1:
The stick is prepared by sd firmware, there should be nothing else on it.
[MTCD Software Development] moreno_cos:
Please HELP! Now HU is only black screen

Step 1- micro sd configured with SD_Firmware_Tool ( uncheck update firmware )

Step 2- USB configured with SD_Firmware_Tool ( uncheck update firmware )

Step 3- Insert micro sd in gps slot and insert usb

Step 4- Reboot

Now mi HU is only black screen :(
[MTCD Software Development] typos1:
Have you read the guide in the 7.1.1 thread ?? You eject the sdcard as soon as you see an image on the screen, this gets you into 5.1.1 recovery then you can nstall 5.1.1.
[MTCD Software Development] moreno_cos:
Yes, I have read the guide.

The Hu is dead, with or without SD boot,

The screen never show an image., it is only black.

The bottons have light.

Please help
[MTCD Software Development] typos1:
Make another bootable sdcard and try that, a smaller card is better.
[MTCD Software Development] moreno_cos:
Solution:

I managed to unlock it with a 7.1.2 bootable micro sd

Later I tried again to do the process for 5.1.1 and the screen went black again and new brick

I have resuscitated it with a 7.1.2 micro sd and I have left it like that
[MTCD Software Development] typos1:
Sounds like you didnt use a 5.1.1 bootable sdcard when trying to install 5.1.1.

I'm looking to install this (5.1.1) or the (7.1.2) version on my old MTCD head unit, it's currently running Malask, which is just a mess and operates horribly in my case.

I want the most streamlined, fastest experience, which version would be the best?
[MTCD Software Development] typos1:
5.1.1

Does anyone know where I can find the original firmware for this radio? To possibly go back to the original.
[MTCD Software Development] Pavel-71:
Give the MCU version and the full build number, preferably take screenshots, you can find it in the settings. According to the current information, it is not possible to determine whether you are in the correct subforum.
[MTCD Software Development] typos1:
Incorrect - he has an MTCD unit with Android 5 so we know that he IS in the correct forum.
[MTCD Software Development] Pavel-71:
Good! He didn't have this information here originally, after being notified he added the information, exactly at 10:15.

Pavel is like one of the only remaining MTCx enthusiasts that keeps these threads on track. Thanks to Pavel! @pavel71
[MTCD Software Development] elman2020:
I uploaded soft hal9k to the radio with RK3188. Everything works well. I can't change the homepage, launcher. I've looked through the entire menu. Where is the change? Maybe you need to upload? In the pictures on the first page you can see 5 types of home page.

[MTCD Software Development] elman2020:
I have an Erisin radio with Hal9k Mod v1.x RK3188 software loaded. In this software, the internal memory is divided into 2 partitions. In addition, the radio has 2 memory cards. I want to save maps on a memory card, unfortunately all navigation programs only see these two partitions of internal memory and not the card. What to do with this? I guess you need to hide one of the partitions somehow. I will add that when I had the original software, this problem did not exist.
[MTCD Software Development] Pavel-71:
#181
[MTCD Software Development] elman2020:
Thanks for the answer, but I have a different problem, the memory is visible, but it is divided into 2 parts. If I want to save google maps to SD card, they are saved in internal memory. User erronr describes it in this thread: #123. Unfortunately I didn't find a solution :(
[MTCD Software Development] Pavel-71:
If erasing and formatting in recovery did not help, you can still try to install Hal9k mod 2.5 #1, select wipe data before installation. Unfortunately, Android 6, 8, 9, 10 cannot be installed on Android 5.1.
[MTCD Software Development] elman2020:
I'm not sure if I understand you correctly. Should I have one partition after installing hal9k? Like most phones? If I have two, does it mean that the memory was formatted incorrectly? In post #9, the user asks about the amount of memory, and hal9k answers that there are two: 4 Gb and 9.5 Gb. My question is: is it possible to combine these two parts into one? I am attaching photos from my radio.
[MTCD Software Development] Pavel-71:
Hal9k mod 1.3 has two partitions, why the navigation does not see the memory card I do not know. No one had a similar problem. Have you tried another file manager like Total Commander? Or try formatting SD cards to FAT32. I don't know if deleting and formatting will help, if you don't try, you won't find out. If you want one partition (FUSE) then try Malaysk#1

or use the search engine and type FUSE, if the original firmware worked then reinstall it, every time you install a new firmware then choose wipe data, if you don't it may cause errors, I have no other advice:

Hello. Need help from the experts. Hope you can understand it, everything written with translator.The image is somehow gone and I want to bring in a usable one.

It's an Erisin ES3026S and Erisin doesn't help because I no longer have the proof of purchase.I would be very grateful for a link for this. I'll come to the repository. If data is needed, please let me know.
[MTCD Software Development] elman2020:
Thanks Pavel-71, you provided me with a lot of information. I need to clarify one thing: all applications see internal memory and SD card (google maps, magic earth etc.). If I choose to save maps to the SD card, then the maps are saved to the second NAND FLASH partition - 9.43 GB and not to the physical SD card - 32 GB, that is the whole problem.
[MTCD Software Development] elman2020:
I have the original system for this radio, if you need it, write me a private message.
[MTCD Software Development] Pavel-71:
I don't know, but you can try to make the SD card an internal storage, maybe it will solve your problem, I found a tutorial and translated it from 4pda:

Go to Settings > "Storage and USB Drives"

"Tap" on the card you want to make an internal storage device (GPS in our case)

Click "Three Dots" > "Storage Settings"

Click on "Internal Storage"

I have to agree here

Now he changed the card, instead of 16gb he put 160gb, before that he forgot to change it.

Check "Move Now" > "Next"

Again we agree

Here is the result

After this it shows that you have 160GB of internal memory and the GPS slot is missing everywhere, only the SD is left, the /data directory has been transferred to a formatted card in the GPS slot. Try transferring the maps there.

does this rom also work on PX5 chipset?
[MTCD Software Development] gunmoule:
PX5 is RK3368. This Rom is not for your device.
[MTCD Software Development] AndroidBricking:
My unit says "px3-userdebug 7.1.1 NMF26X eng.hct.20170527.145603 test-keys" for the build number. Since RK3188 and px3 are the same thing (I think), your rom should work on an MTCD_XRC_V2.52_1 device, yes? My unit runs on 7.1.1., but I do not mind downgrading if I can obtain root. I only ask before trying it because I already bricked one of these before.
[MTCD Software Development] prmah:
If possible please ask your vendor for 7.1.1 android firmware of ur device and share it here.

[MENTION=415542]Alhaddad[/MENTION] Yes. But you need to install Xposed framework and this module.
[MTCD Software Development] Alhaddad:
yes, but i meant without xposed, is it possible to modify the framework and change the volume bar code?

there's no way i'm installing xposed again after the worst experience in Malaysk rom
[MTCD Software Development] Hal9k_:
[MENTION=415542]Alhaddad[/MENTION] Everything is possible, if you want. Do you want to do this? I do not like this bar.
[MTCD Software Development] enes67:

[MTCD Software Development] prmah:
[MENTION=5092263]Hal9k_[/MENTION] can we install this version with 5.1.1 recovery?

This should be without that "red text" at bottom. Or are you going to provide a newer version of 7.1.1 ?
[MTCD Software Development] Hal9k_:
[MENTION=7515547]enes67[/MENTION] You need to install Xposed framework and this module. Instructions for installing Xposed you can find on this forum. I have only a link to 4pda on the Russian instruction.
[MTCD Software Development] Hal9k_:
No. It's need a bootable SD card.

"red text" at bottom will be always present on a stock ROMs, installed on old coreboards with 1Gb RAM.

I think, it is "marketing policy".

Maybe.

And what do you expect from 7.1.1 ?

What do you miss in 5.1.1 ?

I do not see a significant difference in the functionality between the existing firmware 5 and 7.

And I do not really want to do firmware for HU, which I do not have.
[MTCD Software Development] prmah:
That's totally fine with me . I just asked out of curiosity. And you also mentioned in other thread, where you released ur android 7.1 test build , that you will be working on Android 7.1

Hello,

I am coming from a malaysk rom, and it seemed to have all of the internal memory avail instead of just the 4gb as internal. Is this possible with this rom? I download my google music to the device and it won't move to the 'external' storage. Thanks!
[MTCD Software Development] typos1:
Yes, [MENTION=3590033]Malaysk[/MENTION]'s ROM is FUSE, [MENTION=472138]hal9k[/MENTION]'s is not, this has already been discussed in this thread.

Hi!! I have Eonon GA6201F in my bmw E39. I have question, is this rom working better? My devices has small lags, this is terrible. Has this rom apk cameleon 2.0 ? I can in this apk change any rbg colors button. Thanks!!
[MTCD Software Development] typos1:
The ROM is very, very good, try it, it will help with lag because it has microG apps - the Googleservices are what slow it down.

All ROMs contain the RGB LED app, you may just have to turn it on in factory settings.

Your head unit is not Eonon, they are a seller only, go to settings/about device and the letters after "MTCD" will tell you what unit you have. :)
[MTCD Software Development] Alhaddad:
has anyone tried xposed framework on this rom? does it slow it down?

umm, where? :) i just read the whole thread.

i'm on malaysk 11.5 microg and after few days it starts to act strange...losing wifi, blank screens, etc. Awesome pioneer work for [MENTION=3590033]Malaysk[/MENTION], but development on his PX3 "branch" seems dead. I'm willing to give this one a try...

[MENTION=5092263]Hal9k_[/MENTION] is it possible to modify the radio app, so that it mimics somehow the xposed module behavior on malaysk 11.5? Meaning RDS text should remain visible in the preset boxes, not switching between freq and ps_text, eliminate the "rubberband effect" of the preset boxes when scrolling, etc... :) Oh and make it visually appealing, i can help with that if you want, we can take it offline via PM if u want.

I got a joying 8" px3 with upgraded IC amp chip (Pioneer 2030A) and don't really want to sell it, just need a stable and flexible rom for it ;)

i'm waiting for RAM chips to be delivered to do the 2GB upgrade as well, btw.

thx.
[MTCD Software Development] typos1:
Dunno, I d have to read the whole thread again to find out !

Cant see any reason why you cant install Xposed and [MENTION=3590033]Malaysk[/MENTION]'s radio app on [MENTION=472138]hal9k[/MENTION]'s ROM.

Did you know you can do 7floors sound mod to MTCD units ? Imagine the sound with your upgraded amp IC !
[MTCD Software Development] zerozoneice:
yea i know about 7floor HW mod but it's a bit too much :) i'm very happy with the sound now, given the speaker setup.

like [MENTION=5092263]Hal9k_[/MENTION] 's work so far, it feels more solid & less hectic than competitions' :)

yea, the radio app is untouched from original FW, it needs some serious makeover. display countinuously switching mhz & psname and fm preset groups lasso-ing back & forth drives me mad.

i know y'all firing up spotify, shoutcast & co but call me an old fashioned FM fan :)
[MTCD Software Development] typos1:
As I said, you can install [MENTION=3590033]Malaysk[/MENTION]'s radio app and Xposed on this ROM, its easy to do.
