Known issue: On devices with 1 GB due to lack of RAM or another videocodec hardware, the built-in video player and other programs that work with video does not work normally.

Solution: use a third-party video player.

is this fixed on v2.5 or any other version ?? i'm really not sure to switch to hal9k from malaysk now, but i'm hoping it will be even faster.

important apps i'm using:

-dab-z

-fm radio with rds data and text

-torque

-tomtom mobile go

-music player

-dvd video

running on mtcd rk3188 with 1gb ram and 16 rom memory

My unit is 1GB PX3 using recent mcu. Lately I detect a problem with bluetooth and wifi. If I connect the HU with my phone, WiFi speed is greatly reduced. It worked fine with Android 5.

My HU uses the infamous MD725 bluetooth + wifi module, type 1. Can it be fixed in Android 7?

Thanks in advanced.

[MTCD Software Development] abellemare44:
bluetooth is working everytime now, I have MCU MTCE KLD V3.01 and HAL9K V 2.5

I don't know if it's because the MCU update at V3.01 or the update at V2.5 for HAL9K

But it works

Thanks

downgrade

please people any way to downgrade

I'm not able to boot 5.1.1 recovery from sd card to downgrade

every time the unit boot to the nand recovery android 7

I tried many sd cards but with the same result
[MTCD Software Development] typos1:
You need to eject the sdcard AS SOON as "Lollipop" appears on the screen.
[MTCD Software Development] Gerd44:
Hi,

the hardware eject button doesn´t work anymore with the Hal9k Mod. at my Erisin Erisin ES3782s.

It doesn´t ejects the CD/DVD disc, instead it starts/ends the DVD app.

There´s no Code for disc eject at the Mod-Settings.

Can somebody help me?

Thanks
[MTCD Software Development] VictorQ8:
the problem is the head unit boot to the system recovery "Nougat" immediately

it did when I installed this rom but when I want to downgrade to Lollipop it's not booting to my sd
[MTCD Software Development] typos1:
Its booting into Nougat recovery immediately and youre using a correctly functioning Lollipop bootable sdcard ?
[MTCD Software Development] VictorQ8:
Yes sir and I tried more the 6 different cards even new ones, In my unit if I didn't hold the reset button it will boot to the system so I hold it for 10 seconds and release then hold for 3 seconds and the unit boot to recovery
[MTCD Software Development] typos1:
You have not read the instructions properly - you insert the Lollipop bootable sdcard while the power is off, then turn on the power, as soon as "Lollipop" appears on the screen you eject the sdcard, why are you trying to get into recovery yourself ? That will never work because the recovery on the device is Nougat. The word "bootable" means the unit boots from the sdcard.
[MTCD Software Development] VictorQ8:
That's what I did every time

The unit always boot to the system ignoring the bootable sd card, it will never boot to recovery unless when I hold the reset button then it boots to nougat recovery, I tried restarting the unit with same results even removed the car battery but same thing

[MTCD Software Development] ozzyboy:
I've just downgrade from 7.1.2 to 5.1.1 without problem.

I think you are doing something wrong ...

Steps for downgrade are:

1. Prepare sdcard like in first page, BUT for downgrade use 5.1.1 original rom when choose firmware (1GB sdcard it's enough).

2. Prepare USB memory, format as fat32 then just copy on usb the "dupdate.img" (firmware)

3. Put both on HU media, then force a restart. In this moment you will see lollipop screen for 3-5 seconds then it boots in with a message "Doing actions failed! please remove sdcard......."

4. Remove sdcard and wait ... HU reboot in lollipop recovery

5. Then here choose "update system/mcu image from usb and clear all".

6. Wait few minutes... android is loading and configuring.

Good luck!

L.E. ....And if it not works in this way, maybe you have a problem with your GPS sdcard slot from HU, maybe it's broken and in this case maybe it's possible somehow to use the other one sdcard slot, but here I can't help u anymore!

Hi can you send me a link for launcher 4 (looks like carplay) i have downloaded all launchers from yandex there is no launcher 4

Thanks

I have found the theeme inside the rom!! Thanks
[MTCD Software Development] dasJens:
Hi.

Sorry for my bad English. My german is much better. :)

A few days ago I upgraded my radio with the costum rom of Malaysk. Then I wanted to try this one out.

Unfortunately, I do not get the recovery of nougat to start.

If I am with 5.1.1. in the recovery boats, there is always the error that external_sd is not found.

Apparently it's because the GPS SD card is mounted on USB_3.

Are there any solutions or is this normal?

I have formatted the SD card with the tool (without the hook for firmware update) and copied the image to a FAT32 USB stick.

It always starts lollipop. : /

Hello there,

I download the file to USB. I'm connecting to the multimedia system. But the file is not found in the update phase, he says. Why could it be? Help please.

FAT32 format.
[MTCD Software Development] typos1:
Try downloading again, try a different sdcard or usb stick, just keep trying - Nougat on RK3188/PX3 chip can be VERY tricky to flash.

Youve booted to Nougat recovery using a Nougat bootable sdcard I assume ?
[MTCD Software Development] crewd0x:
Hello,

I get the same error despite downloading 3 times :(

I tried it with 3 different usb flash drives. I tried with 2 different micro sd but the result is the same :(

I'm going to update the settings after installing usb. do I need to do something different?
[MTCD Software Development] typos1:
You didnt answer my question.
[MTCD Software Development] crewd0x:
Sorry, my English is not good. I don't understand what you wrote :(
[MTCD Software Development] typos1:
Ok, please use a translation site then, because its important that you understand things correctly and I m quite sure that its because you havent understood how to flash Nougat on a Lollipop device that youre having problems.
[MTCD Software Development] crewd0x:
as far as I understand my device is lollipop, if I want to install nougat. is it correct?
[MTCD Software Development] typos1:
That sentence does not even make sense, read the thread from the beginning with a translation site.
[MTCD Software Development] dasJens:
Hi.

Where you are from?

You have to create an SD card with nougat with the instructions in the 2nd post and "boot" your radio over it.

https://xdaforums.com/showpost.php?p=75358408&postcount=2

Only then does it even recognize the image.

At this point, I'm stuck synonymous, because with me the SD card is mounted as USB_3 and not as external_sd. : /

Thus, the SD card is not queried when booting. :(
[MTCD Software Development] typos1:
Again your sentence does not make sense, please use a translation site to read at least the first few pages of this thread.

Things that i tried

With [MENTION=472138]hal9k[/MENTION] 7.1.2 bootable sdcard i can get into Nougat recovery menu, tried clean wipe cash, factory reset options and finally update again, there is no solution still stuck nougat logo.

With stock rom(5.1.1) bootable sdcard i cant get into lollipop recovery menu. Stuck on lollipop boot logo. Tried eject the sdcard as soon as possible when lollipop appears many time, doesnt work.

i never update dmcu, it is same as it was.

İ thing it is bricked, please ineed some advice, i m very sorry for beeing such despered

Edit: i apply this method to flash som with;

1- stock dupdate.img. Flshing succesful but stuck on boot again.

[MTCD Software Development] Melgawa:
Greetings !

I have been using your firmware (2.5) for almost a year by now, and it works like a charm !

I have 2 simples questions, maybe you have an advice ?

1/ the radio app keep searching without asking. Is there any option to 'freeze' a setting even if it's poor reception ?

I have a poor reception but I haven't been able to do anything about it : antenna checked, ground everywhere...no ant amp yet but thinking about it.

2/ the sound is not great...probably coming from my setup as well (Fiat Ducato) but do you have anything to recommend ? I have been playing a bit with the equalizer, but what is the difference between regular EQ and Viper for Android ? Do they overlap ?

Many thanks and keep up the great work !
[MTCD Software Development] typos1:

i think microG is causing issues,especially when you switch to Gapps after installing the rom.

Its not an Erisin, its a KGL unit.

Its an MTCD/E unit, so yes, you can upgrade the SoM to an RK3368/PX5 (octacore), an RK3399/PX6 (hexacore) or an RK3326/PX30 (quadcore). All these have 2 - 4 Gb RAM.

Enviado desde mi CLT-L09 mediante Tapatalk
[MTCD Software Development] typos1:
You have to replace the SoM (System on Module) inside the unit with one of the ones I mentioned.

You could also add 1Gb RAM on your current SoM and update it to Nougat (you can update it to Nougat now also, but I would not recommend it with only 1Gb RAM).

And how can I add 1 GB of RAM to my radio? You catch me again and I don't find out much. And with 1GB of RAM you tell me that Nougat is risky, but would Android 6.0 be fine? With only 1GB? Or for 1gb the best android 5.1.1?

There a several threads about how to add 1Gb RAM.

Nougat does not run well with 1Gb RAM, you cannot have Android 6 Marshmallow on the RK3188/PX3.

Yes you can use this ROM, thats why I directed you here :)

Probably unlikely anyone has tried the Sony Xposed framework, possibly someone has tried Magisk, flash the ROM and see, as I said before, I wouldnt recommend using these stereos without a custom ROM.
