Does anyone know the manufacturer behind the SoM's >> ? HCT , the price asked on aliexpres is ridiculous, The PX5 chip sells for 11 USD from Rockchip, cost for that module should be lower 40's
[MTCD Software Development] typos1:
HCT makes the SoMs, you could try going to them direct if youre not happy with the price. Of course its rather more than the chip youre buying, its also the RAM, the flash, the GPS chip, various controllers etc.
[MTCD Software Development] henri_p:
Well, that was exactly my question, who is HCT, i cannot find any website or reference.

We produce SoM's, mainly NXP and TI products, so I know the price is strongly exaggerated
[MTCD Software Development] cupi1234:
HCT - HENGCHANGTONG

http://www.hctsz.com/
[MTCD Software Development] typos1:
SoMs for what? The price is set by the retailer not the manufacturer
[MTCD Software Development] henri_p:
We make for example the Wandboard and also the new Android things Dev kits .

Yes, the price is set by the retailer, that is why I search for the manufacturer. :good:

[MTCD Software Development] H0U5ECAT:
I've tried multiple time to flash the update, but it keeps failing.

Rooted mtcd xtrons rk3188.

I've updated it via the system update and it recognises the file and goes into reboot mode and recovery

I'm running stock so I choose the fifth option, update via usb and clear, but it fails trying to update the mcu.

I've tried the fourth option also. still no luck.

I've also tried to rename the image to just update.img but this also isnt working.

Any help? Cheers in advance
[MTCD Software Development] typos1:
You appear to be talking about the ROM and the MCU but you say "the update", they are 2 separate updates.

I dont know what you mean by "I m running stock so I choose the fifth option" - it deosnt matter whether youre on a stock ROM or not, try from SD and if that doesnt work try re-downloading the updates and also try re-formatting the sd card/usb drive if re-downloading the updates dont work.

If it fails updating the MCU the ROM should still flash ok, so surely its also failing to update that as well ?

[MENTION=5331038]H0U5ECAT[/MENTION] show us a screenshot with Version info (as in the 1st post) and the video of the upgrade process.
[MTCD Software Development] H0U5ECAT:
Image attached.

Sorry, I'll try to be clearer.

I downloaded and extracted the RAR file. and loaded the image to a USB, formatted to fat32.

There were only 3 files in the rar. An dupdate.img and 2 readme files

Via the "system update" in settings, I tried to load the image.

The unit found the .img and went through the process.

I chose "Update via USB and clear" option first. I also clicked the wipe and clean option before choosing the image to update.

The unit went through the update procedure, but there was a few lines where it said "failed".

I couldn't read it as quick as it let out the script. But it did say it failed to update the MCU.

Then I had to reboot the unit.

I tried the other option after doing the process again by choosing "update via USB", and still no luck.

Image of the system attached.

Thanks again for everyone's help on XDA. I would have had many sleepless nights without everyones input.
[MTCD Software Development] H0U5ECAT:
I'll try to do it again and record it a bit later.
[MTCD Software Development] zerozoneice:
of course it failed to update MCU because there is no MCU file in the package.

this ROM only updates the system image.

first thing before attempting any update is to verify if you can enter the recovery. Did you test it?
[MTCD Software Development] H0U5ECAT:
I'll give it another crack by booting into recovery instead.

I thought the system update would have solved my problems...

Cheers Zero.

no luck
[MTCD Software Development] zerozoneice:
maybe corrupt download, bad usb stick...

download the file again and unzip the image file only to another USB stick (formatted as FAT32) with nothing on it except the dupdate.img file

choose wipe data/factory reset

then choose update from USB and wipe all

if it fails, go to recovery again (if it doesn't go automatically after reboot) and choose again update from USB

if it still doesn't work, repeat process using another USB port (if you have another one) or a SDCARD.
[MTCD Software Development] typos1:
Try it using the SD card and whilst its fine to update the ROM and MCU at the same time as your having problems just do them one at a time.

Download the ROM again and try again.

Play Store issues

I've flashed this ROM and I am getting the RH-01 Play Store error with the microG configuration. Could anyone help me solve that? I've been looking around the internet and these forums for a few days, but came up empty. The microG Play Store seems to need additional manual configuration after installing the Malaysk ROM, but I could not find any such instructions for Hal9k.

Otherwise great ROM, expect a donation from me.
[MTCD Software Development] Hal9k_:
[MENTION=8500212]Atlanntas[/MENTION], thank you.

Just read the post #2.

"How to switch to microG ?"
[MTCD Software Development] Atlanntas:
Thanks, previously I had only followed the readme within the archive. The microG settings app was missing for some reason, although I did switch the framework a bunch of times with various G apps disabled, maybe that's the culprit. I did a factory reset and then the microG settings app was there, I was able to successfully configure it.
[MTCD Software Development] Hal9k_:
Glad you did it.

MTCD LM with radio & clock problems

Very compliments for this version.

I try it on 2 devices but I have same problems ok both device:

- Clock : i set GTM +2 but when i switch off the car, i loose this setting.

- radio: if I store some freq., when i switch off device i loose all setting.

How I can solve?

Thanks a lot
[MTCD Software Development] CjSury:
Hi guys!

Great ROM!!

Is possible to do scroll or move in the display where contacts are shownd?
[MTCD Software Development] Hal9k_:
1. I do not have this problem.

Did you connect wires BAT and ACC correctly ?

The navigation software can change the timezones.

2.Set the "Default power status" in Factory settings to "Memory the status of last".

This helps to keep FM presets.

Of course. It scrolls from top to bottom.
[MTCD Software Development] CjSury:
Sorry!

Is this possible from the buttons on the steering wheel?
[MTCD Software Development] Hal9k_:
As i remember, no. From the steering wheel you can only redial the last number.
[MTCD Software Development] nosidefcp:
ive read here about the 7.1 rom without red text...can someone post the link please?thanks
[MTCD Software Development] typos1:
Plenty of links in this thread, you just gotta read it . . .
[MTCD Software Development] nosidefcp:
I was an heavy user of several quadcore r16 from allwinner UNITs, and there were Also issues with a red text string. That was solved in the 4pda forum. I will check if it works in the rk3188 and ler you all know
[MTCD Software Development] nosidefcp:
in order to remove the red string/text in the r16 quadcore units, they changed ro.fota.device from JYZC1_0024 to JYZC1_0000 in the build.prop.

i cant seem to find any ro.fota.device in the unit build.prop...
[MTCD Software Development] typos1:
Hmm, it maybe somewhere else then, it may even be different thing thats doing it.
[MTCD Software Development] AndroidBricking:
Does your mod support TPMS modules that plug into the back of the unit? (Not USB, but a multi-pin connector)
[MTCD Software Development] nosidefcp:
It is not present in 5.1 build.próprio, but i can have a look in 7.1. Can i downgrade fine from 7.1 to 5.1? If yes, when i get home i will havê a look in 7.1 build.prop
[MTCD Software Development] Hal9k_:
The same as in the stock firmware. In this part, I did not change anything.

Hi , is it possible to change a MTCD-HTWX firmware by your fimware MTCD hal9k ? will it brick my system , or not ?

---------- Post added at 10:03 PM ---------- Previous post was at 09:56 PM ----------

just read the forum , apparently , it will do !

sorry for the ( repetitive ) question i have ask

---------- Post added at 10:27 PM ---------- Previous post was at 10:03 PM ----------

so the new question is : how do i go in recovery mode with a system that have no physical button ( except reset ) ?
[MTCD Software Development] typos1:
Yes you can downgrade details are in this thread.

If you have an RK3188/PX3 1Gb RAM unit running Lollipop you can use this firmware, not if you are using any other processor or an RK3188/PX3 running N.

the attached picture explains how to get into recovery.

Best ROM ever on my 1gb mdcd unit. One question. Is there any way to run iPod application and play music via usb cable from iPod/iphone?

Thank you in advance.
[MTCD Software Development] typos1:
Yes, the same as any other ROM - go into factory settings and tick "ipod", this is nothing to do with the ROM, its MCU controlled.
[MTCD Software Development] munio.pl:
Thank you for clarification. So please let me precise my question. How to get iPod app running? I am using MTCD_KD_v2.40 MCU. Does anyone managed to run iPod app? If so, which MCU should I use?

Thank you in advance.
[MTCD Software Development] typos1:
Lol, I ve just told you - go into factory settings and check the option marked "ipod" !!
[MTCD Software Development] munio.pl:
LOL, if this would help I would not ask... I tried on several MCUs. After turning on iPod option in factory settings, app appears but it does not work.
[MTCD Software Development] typos1:
Ah, well you never said that !

Has it worked on other ROMs then ?
[MTCD Software Development] munio.pl:

Could you please try to open it on your device? On mine it crashes one second after opening.
[MTCD Software Development] typos1:
With or without your ipod plugged in ?
[MTCD Software Development] munio.pl:
With or without iPhone plugged in.
[MTCD Software Development] typos1:

[MTCD Software Development] viperx888:
I have a few questions before I consider doing this mod.

Does this custom rom speed up the loading of applications such as Spotify and GooglePlay Music? I think my current stock 5.1.1 system is quick with the 1.6Ghz Cpu and 1GB ram, for navigating through device settings, but it feels very very slow when initially loading applications such as googleplay and spotify. Would this custom rom give better performance for applications?

Second question, am I still able to use the subaru logo as my loading screen during the boot process?
[MTCD Software Development] typos1:
Yes, because it uses microG.
[MTCD Software Development] Hal9k_:
I think, yes.
[MTCD Software Development] nosidefcp:
hi. my volume wheel*knob is swithing radios instead of increasing/decreasing volume...any tip?
[MTCD Software Development] madiskallas:
Thank you very much for this ROM. I tried to use Malaysk ROM for half a year, but was always sluggish and wierd. Your ROM is very fast and easy to use.

I've got a question though. I want to add applications to the "sleep whitelist", but I don't know how I could get the correct strings for it. For example I want DVR and CoPilot to be left running when unit goes to sleep. What exactly should I write into this whitelist in settings?

Also, I want those two apps to start running when I start the unit up (not sleep, cold start). I've used a startup app so far, but is there a neat and better solution for that?
[MTCD Software Development] rohithp:
Thanks

Hai Hal9k,

yesterday i have installed your ROM and i am very happy to say that its working perfectly fine better than stock ROM. I got lot of new options in my settings. Thank you. Looking forward for better updates
[MTCD Software Development] Pegasoman:
@hall9k I have a couple of questions:

1- Can I install your ROM over one that has FUSE? Is it enough to wipe all data?

2-Can I delete icons from the status bar?

Thanks in advance

Yes to both questions.
[MTCD Software Development] ruirocha:
I need your help.

I followed the steps for enabling microg, but I can't use YouTube. Says I have to update Google services. Tried to update but gave me error.

What am I doing wrong?
[MTCD Software Development] Hal9k_:
Use this app, for example https://play.google.com/store/apps/details?id=com.gijoon.pkgnameviewer to get the package name and add it to the list.

No, there is no such built-in application. Use third-party.

This problem exists, but I have not dealt with it yet.

You can try to install an older version of the YouTube app or look for a solution in the microG thread.
[MTCD Software Development] devilsoft:
You can use my app from https://xdaforums.com/showthread.php?t=3246437 to run any app, on startup.
[MTCD Software Development] here is johnny:
Hello,

First of all thanks for the effort to make such a rom. I only knew malaysk rom.

So yesterday I installed the rom yesterday, after switching to microg, which I am not familiar with, I can't download any apps from the appstore is that right? I should download first with Gapps option first and afterwards switching back to microG for speed? Or did I do something wrong? With microG the speed is perfect. With gapps.. well you know..
[MTCD Software Development] Hal9k_:
Did you followed the instructions in post 2?

Steering wheel control

Dear Malaysk,

I have installed your ROM last week. I wanted to share one problem which i am currently facing after installing your ROM. My steering wheel key functions are not working properly. Sometimes volume up key wont work, sometimes next button wont work. So every time after starting the car i have to configure with the steering wheel control buttons. Any solution for this?
[MTCD Software Development] typos1:
This is the thread for [MENTION=5092263]Hal9k_[/MENTION]'s ROM . . .
[MTCD Software Development] here is johnny:
Yes.. Well sort of..

I did what I wrote earlier, downloaded the apps from the playstore and converted back to MicroG.. But I can't really use Google Maps, because it is to slow, and spotify takes a lot of time to start.

First install it worked as a charm, but after reversing it back to Gapps installing apps and then back to MicroG it slowed down..

So now i will try to but the apk's which i want into the descriped folders in post 2 of your thread. And leave the rom on MicroG, oitherwise I will have to try something different..
[MTCD Software Development] hugovw1976:
I have a similar trouble, I can't signin on play store and if I try to use maps or youtube allways have a message about upgrade google service but if I try to update have a fail message.

I updtate microG to the latest version from here: https://microg.org/download.html and everything works fine now.
[MTCD Software Development] typos1:
So youve installed all the apps on that download page ?
[MTCD Software Development] hugovw1976:
Just the first one (services core).
[MTCD Software Development] typos1:
Ah, ok thanks.
[MTCD Software Development] here is johnny:
Thank you, maybe that will work for me too, does your playstore work as well? and the speed of the unit?
[MTCD Software Development] hugovw1976:
Play store work fine, about the speed, I have my unit on work bench not in my car I can't made a full test for speed sorry.
[MTCD Software Development] munio.pl:
HI Hal9k, apologies if this question has been already answered within this thread, but I did not find an exact answer. Currently I am using rk3188 1GB of RAM KD unit. It works quite well with your ROM (the best ROM ever, by the way). I am going to upgrade my HU and replace it with 2GB rk3188 unit. What should I look for/ask seller to make sure that it will support your rom? Thank you in advance.
[MTCD Software Development] typos1:
I assume you mean a unit running Nougat ? If so it wont, his ROM is only for the 1Gb RAM L units, theoretically your SoM could run his ROM (the older 1Gb RK3188 MTCD SoMs can run N), but you would have to ask him to modify it to run. He was working on N for the older 1Gb RK3188 SoMs but he hasnt announced anything yet. For more details simply read this thread.

You could keep your current unit and upgrade it to 2Gb RAM, then you would be able to run his ROM without any mods, probably would be cheaper too.
[MTCD Software Development] munio.pl:
Thanks for prompt response. I read the whole thread, but maybe I lost something in translation. I thought that Hal's rom is applicable for all rk3188 boards. Currently I am looking at - https://www.aliexpress.com/item/Qua...c-android-4-4-for-BMW-E46-M3/32449072913.html

This one is running 7.1.1 but I am afraid that it will be slow running all this useless android stuff.

What I need is simple, responsive HU, with light ROM to run spotify, google maps and one other Polish region specific app -Yanosik - that is all.

Can anyone suggest which HU with 2gb of Ram should I use?

Sorry for off topic.
[MTCD Software Development] typos1:
I thought it was this thread that had discussion about L and N ? Maybe I was wrong. His ROM isnt really applicable to all boards, only the rev0.02 1Gb boards, as I said I m sure he could make it run on a 1Gb rev0.3 SoM - he got the ROM from the rev0.3 SoM to run on the rev0.2 SoM. He has said he is working on N but also that he cannot really make a version for the rev0.3 N SoMs as he doesnt have one of those. I have volunteered to test it on my unit if he wants.

The only reason the 1Gb model is slow is because it only has 1Gb RAM, an L RK3188 SoM upgraded to 2Gb RAM will be pretty much as fast as the N one. So if you want to use this ROM, I would recommend simply upgrading your SoM to 2Gb RAM and then running this ROM. You could also run N on that if you wanted, it wont be a custom ROM and it will say "test version only" at the bottom of the screen all the time, at least until someone finds a way of getting rid of it ! There a few threads in the forum about upgrading the RAM.

Actually while I think about it [MENTION=5092263]Hal9k_[/MENTION] if I gave you a copy of the latest 2Gb N ROM, is there any chance you could make a version of it to flash on a 1Gb SoM, like you did with the first release ? :)

After installing the ROM I have a problem with Navigon.

I can install Navigon from Playstore but when it starts the screen wents black only the statusbar shows "Navigon" and some other infos. Any idea?
[MTCD Software Development] s.rahus:
Hi Hal9k,

This is slightly off topic. But since you are so familiar with these ROM implementation, I thought I will ask it here.

How the input from microphone handled by Bluetooth and the android ROM on the MTCD devices? On the new MTCD devices running 7.1.x, the microphone works brilliantly during Bluetooth calls, however it would not capture anything while using google voice search or any other voice recording apps. What can be the issue, any idea?

Thanks in advance!

Cheers,

As with all MTC models it varies depending who manufacturers your unit, the processor is not relevant, its the motherboard that is.

This is awesome!

Can I use this time to downgrade my PX3 2GB ram with MTCD_MX_V2.56b_1 currently running Nougat 7.1.2.

I need to root my device to apply the USB audio mod to the audio policy file but am unable to find any way to root currently.

Does your room have the USB Digital Audio MOD applied??

[Edit] I went through all 33 pages but cannot find a clear answer.. Sorry if I have missed it. Can I downgrade my PX3 2GB ram with MTCD_MX_V2.56b_1 currently running Nougat 7.1.2 to this ROM? I currently do not have Root access..

From what I have read this ROM works with the 1GB ram version PX3. What about the 2gb Ram newer PX3? I know this is a L ROM and I don't mind downgrading...

Hi [MENTION=456516]typos1[/MENTION],

Yes I did see this reply from you but just wanted to clarify what you meant...

I know that [MENTION=472138]hal9k[/MENTION] has not yet released the N version of his room but if I were to load this room it would downgrade it to L, which I am fine with. Is that also not possible?

Is there any way I could get root? I don't mind L, M or N. Just need root. I am unable to find any thread that is dedicated for a custom rooted ROM (L,M, or N) specifically for the PX3 2GB chipset currently running N.

Would really appreciate some guidance please because without root I cannot do the USB digital audio MOD.

Arshish
[MTCD Software Development] typos1:
As I said, putting this ROM on a 2Gb N unit is theoretically possible, but [MENTION=5092263]Hal9k_[/MENTION] would have to slightly mod it to work, just as he slightly modded the N ROM from the 2Gb units to run on the 1Gb units. There are differences to the partitioning between the 1Gb and 2Gb units which is why he would have to mod it for it to work.

You could try Kingroot and Kingoroot, thats what some RK3368/PX5 users have used, you could also read the wiki about MTCB/C units in my signature - there is a code to get root, its worth trying that, cant guarantee it will work, but its worth trying.

So you have a 2Gb N unit ? Or you have 1Gb L and want to upgrade ? Because as I also said, it would be easier to upgrade to 2Gb RAM if you have a 1Gb L unit.
[MTCD Software Development] arshish1612:
If [MENTION=5092263]Hal9k_[/MENTION] has modded the 2GB N rom to run on the 1GB uint, has he also made a rooted version of the 2GB N rom for the 2GB unit itself? I could use that if available..

root just crashes on startup. Have not tried KING Root.

Also tried it *#hct#root#. Does nothing. Says incorrect password.
