It happens. The easiest way to do a wipe.

You can try to replace the required files manually in /system folder.

You can, with known restrictions when playing video.

just tried it out on my crappy 1GB ram joying headunit and it's quite surprising. Initially, everything seems to work / look good , tested bluetooth, canbus, dvd player, media player all working.
[MTCD Software Development] Dukenukemx:
But it works if I use something like VLC? That doesn't sound too bad, but is 7.1.2 faster than 5.1.1? My stereo is still extremely slow in response time for some reason. Like starting up Waze could take a minute before I can actually type in an address. I know that might be due to only having 1GB of ram but I've got other stereos with 1GB of ram without the horrible response time delay.

Also, the stereo couldn't see the rom, do I need to enter recovery for it to find it? I was trying the upgrade button before and it didn't see the image file.

[MENTION=5092263]Hal9k_[/MENTION] I recently got this headunit (see pic attached) made for BMW X1. Sold by "MEKEDE" on aliexpress: https://www.aliexpress.com/item/New...dia-player-Autoradio-for-BMW/32885077467.html

1. I can't figure out if this is an MTCD unit. Its advertised as a RK PX3. Will your rom work on this?

2. If so, this unit has a launcher made to mimic the look of the BMW original infotainment system. Can this launcher be extracted and used with your rom?

Thanks for the help.

It does not matter.

Show the photo (video preferred) with the process of the error occurring.

Thanks for trying to help me.

My problem is that the unit doesn't boot on SD card. I have a white screen on startup. I didn't manage to have the nougat recovery.
[MTCD Software Development] Hal9k_:
If you already have Android 7, you do not need to create a bootable card. Just follow these instructions:

Format the SD card in fat32 and copy the nupdate.img file to sd root. Boot unit to recovery, аpply system image from SD card.

This requires version about 2.5 or higher.

Your video helped to answer.

The video shows that the HU is booted into the system after pressing the reset.

So it should not be. In this case, the HU must load up into recovery.

Since you have Opel HU you have USB1(2,3..) instead of GPS in the Music, right ?

Thus, you will not be able to update with this method.

Try to flash fw again and then do the wipe.
[MTCD Software Development] fabro91:
Yes my SD card is viewed as USB.

Is there another method to update my unit to 7.1.1?

You've made a version test upgradable with Android 5.1.1, is it possible to flash the test ROM and after flash this rom?

[MTCD Software Development] Hal9k_:
Install your core board in the HU with a real sd-card reader.

Connect core board to the PC and flash from PC. The description of the connection was on this forum.

I think not because of the difference in the partitions.

The boot card must be ejected after booting and is no longer used.

How to understand it ?
[MTCD Software Development] R4m80:
After I remove the sd card with the Nougat recovery from the HU and I go into recovery on the HU, I just get a black screen. Is this correct?

[MTCD Software Development] msj33:
Just upgraded my 1GB PX3-KGL unit from Malaysk 5.1 version 10 ROM - I reallylike the 7.1.2 release in simplicity and features...........but:

-No gains of running microG here:(

-Have severe performance issue(Memory?) - Unresponsive and MANY ggoogle wait/stop popup on apps.

-Google Maps does only work once in a while - Reeeeeeeaely slow to start up and freezes very often.

-FM Radio app is gone!? - But the launcher has it on the front page.

Is there ANY chance of getting memory optimizations on this 7.1.2 ROM? Alternatively thorugh an App or deinstallation of "something"

Can I get any performance optimizations by upgrading the MCU? (Running default here) - And Anyone knowing what latest KGL MCU is on and available?

Unless I can solve these performance issues, I have to roll back to Malaysk or try Hal9K 1.3 - But do prefer 7.1.2 :(

Thanks in advance - Very good efforts done here:)

Second question.

Will I be able to use any 4G dongle with this ROM?

I already tried a T mobile 4G dongle with stock ROM and unit was not able to see it.

That is why i am using a old 3g phone as an hotspot
[MTCD Software Development] meazz1:

2nd question: I don't know
[MTCD Software Development] raptor_demon:
first off, thanks for creating these roms!

a few weeks back i managed to get 7.1.2 v2.2.0hal9k installed on my px3 1gb ram.

it was running really slow so i decided to do a factory settings reset. this caused the headunit to lock up and just be stuck with a black screen and would not boot.

i attempted to reinstall the rom using the same methold as used the first time and i can't get a new rom to install. it seems to no longer have the recovery menu.

attempts to install a new rom via the system update fails also, resulting in a black screen.

any ideas what im doing wrong?

thanks

[MTCD Software Development] typos1:
Its not a CAN Bus issue, its a software issue - the devs have not written any option to change the readout to mph for ANY vehicle

Go to settings/about device, if your MCU is MTCD or MTCE and you have a quadcore/RK3188/PX3 processor then you can use it.

xtrons is NOT the manufacturere, "HH" is the manufacturer.

No

No, you need to remove the sdcard AS SOON as "Nougat" appears on the screen.
[MTCD Software Development] Crimas:
Thank you

First of all,

I want to say thank you for your really great job.

Reason why I was looking for a firmware upgrade was to find a final solution on a really big bug on factory firmware. Even if I did your upgrade to last version problem Is still present. Not for you trust me because improves are great. Actually RDS specifically AF function did not change keeping alternative frequency to same station of before when need to change due to lack of coverage. Radio change to any other station without any logic.

Do you mind is this something you can solve with any future upgrade? :fingers-crossed:

Thank you again

Additionally I noticed that kernel adiutor is not applaying setting at startup.

Do you know how to fix this issue? How to overclock android 7 version to 1.6ghz or even more? (I added big heatsink, so my unit probably could handle a bit more than stock)

Guys, what am I doing wrong?

I want to install this ROM on my HU (Witson W2-A5753 Andoid 5.1) and no matter where I put the update image, it doesn't read it at all. Every time I displays me an error like "No update image file".

Either on the SD either on the memory stick on USB1, I shows the same error. They're formatted as FAT32 system file.

I can't boot in recovery mode on my unit. I tried many ways, but never made it. I only have a reset button.

I attached some pictures.

First with the HU's front view (CD300 on Opel Insignia 2010).

Second it the HU's version info page.

Third is the error I encounter every time.

Does anyone know anything so I can make it after all? Or no hope?...

I only wanted to go back to L to sort pout an MCU prblem after flashing an HA MCU on an MLT unit, I ahvent sorted it yet so its still never booting.

hats what es doing !!

It doesnt matter who the ROM is from as long as its an MTCD/E RK3188/PX3 L ROM.

Cos youre not doing it right - you need to get into Nougat recovery to flash Nougat, thats why the instructions say to make a bootable sdcard from the Nougat image and use that to get into Nougat recovery, then flash the Nougat image (as a normal update image on a separate sdcard). It doesnt actually matter if you flash the Nougat update via USB or sd, but you can ONLY do it via Nougat recovery and you can only get into Nougat recovery using a bootable sdcard.
[MTCD Software Development] Phlom:
Hello!

This time I used the SD_Firmware_Tool.exe application to format the SD card and I've made also a Memory Stick just in case. But again couldn't make it.

I hope again it's something I'm doing wrong.

The instructions are:

When I hard reboot/restart the HU (cause turning off just puts the HU into a sleeping/hibernating mode) from the hidden button, the unit boots normally, like usual. So can't get into Nougat recovery mode.
[MTCD Software Development] typos1:
Stop everything and READ the WHOLE thread, you clearly have not understood it !! And also read my last post cos you havent understood that either.

It doesnt mention formatting the sd card, it says you make a bootable sdcard with the image using sdfirmware tools, you use that in the sdcard slot (the GPS on) to get the unit into Nougat recovery, then you use another sdcard with a normal update image on it and use that or a usb stick (or an sdcard in a usb adapter) to flash the update from Nougat recovery.

I have told you twice and its mentioned numerous times in this thread, you need to follow the instructions.
[MTCD Software Development] Phlom:
Mate, my english ain't good enough to express some ideas. I meant "boot sd" not "format". So sorry for the missunderstanding...

A thing I couldn't read anywhere here is if in the application "SD_firmware_tool.exe" do I have to check the "SD Boot" also or uncheck the "Upgrade firmware" only?

I tried to check the "SD boot" and the application stops working. I'm on Win 10 Pro x64 operating system.

LE: I don't have any SD card or memory stick of 2-4-8GB, but only 16-32-64GB... Is this important?
[MTCD Software Development] typos1:
OK, you meant you made the bootable card.

Firmware upgrade - [MENTION=5092263]Hal9k_[/MENTION] definitely says that twice in this thread.

Download the firmware tools program again if its not working, maybe from somewhere else.

The size of the sdcard isnt important.

Can you tell us how though? You see us over here losing our minds trying to figure out

please read what we wrote, we did all that, lollipop recovery refuses to recognize the dupdate.img file.

So my question for typos and slumpz is this, if i name the lollipop image nupdate. and flash it using nougat recovery what will happen?

Also, i don't have the original ROM from my provider, and even if i did wouldn't it be the same issue? (ill try to find it)

---------- Post added at 08:18 PM ---------- Previous post was at 07:32 PM ----------

So I found the rom from.original provider but it's still in dupdate.img format. Should I use it with firmware tool?
[MTCD Software Development] masri1987:
alright screw it, gonna use the dupdate.img from my stock firmware sent to me by xtrons, will create a lollipop recovery bootup sd card using firmware utility tool, and try to downgrade from there. will report back

---------- Post added 4th February 2018 at 12:20 AM ---------- Previous post was 3rd February 2018 at 11:50 PM ----------

reporting back that even using the lollipop recovery image created from stock firmware on firmware utility tool it would not recognize dupdate.img from hal 1.2 mod or stock firmware dupdate.img.

If i rename dupdate.img to nupdate.img and flash it within nougat recovery will i brick my device?
[MTCD Software Development] slumpz:
It will, because each image has different partition scheme and needs to be flashed with correct recovery version.

Are you sure you loaded Lollipop recovery? Did you try flashing your supposed Lollipop recovery with a proper Nougat firmware file (nupdate.img) and see the result? If it can't see dupdate.img, would it be able to see nupdate.img?

Another possible scenario, recovery might want to flash .mcu as well. Try to download a mcu compatible with your device and put it there. Remember to save mcu config first. Feel free to dig the mcu threads.

And lastly, if your device is bricked, it's not my fault :))
[MTCD Software Development] typos1:
No, it wont brick your unit, it will probably just not flash cos of the "n" in front of update, I ve tried it myself before.

L and N recoveries look different and clearly display what thney are at the top of the screen, so tehre can be no doubt what recovery he is in.

You cant flash an Nupdate from an L recovery or vice versa. The L bootable sdcard hes using will get into L recovery, its not "supposed" - it IS L recovery.

Flashing an MCU will make no difference to the ROM or the recovery.
