Hi. My uncle bought a MTCC-KLD6-v2.97 device and installed it into his car, only to find that DAB did not work as he expected. He asked me to try a different OS, and while I didn't believe that'd fix it I figured I might as well try. I first installed the Malaysk 4.4.4 ROM and it ran just fine, but no DAB app. Then I tried to install 5.1.1, and that "bricked" the device. It got stuck in recovery with messages saying that it couldn't mount a bunch of partitions. Then I followed the guide in this post to reset it, and I got to a boot screen, but it bootlooped. So now I'm stuck with a recovery that displays unable to mount errors, and a os that bootloops.

What happened when I tried to unbrick it:

1. I created the bootable sdcard and the usb with the OS.

2. I booted the device (from no power) with the bootable card in GPS slot. This errored.

3. I removed the bootable sdcard. It went to recovery (while showing unable to mount messages).

4. I installed OS from recovery. This seemingly worked (for the most part), but with some error messages along the way about things being aborted.

5. Rebooted and got bootloop (which was an improvement from it going straight to recovery, but still broken).

Do anyone know how I can fix this?

How did you brick the unit, did you flash the wrong Rom type?

MTCD rom will not work on MTCB/C units...

[MTCB Software Development] typos1:
Keep trying, you have to use the exact same OS version that the unit was flashed with when it was bricked.
[MTCB Software Development] pcmender2005:
Hiya mate did you manage to sort yours out
[MTCB Software Development] typos1:
Sort of - I restored it using a copy of 4.4.4, but flashing any version of 5.1.1. (factory or custom) resulting in the unit never booting into Android (continuous boot logo) but happily going into recovery, wiping cache multiple times did nothing, I got errors about not being able to mount different partitions on the eMMC - the same problems I got before it was "bricked" (I put that in inverted commas because it boots to recovery, its not fully bricked but Android rarely starts). A few times it would boot to a bank screen with the home and volume icons at the top but these did not work and neother would any other buttons. The unit is running a MTCC MCU so there shouldnt be any problem with the MCU check on KLD 5.1.1 ROMs.

It seems that it just wont run L for some reason.
[MTCB Software Development] Alxandr:
I tried to install Malaysk 5.1.1 (from this thread).

So, I download the rom from this thread (first post) and put that on bootable sdcard + usb? Not the roms linked to in the "unbrick" post?
[MTCB Software Development] typos1:
I m pretty certain that the "unbricked" post specified that you MUST use the ROM that your bricked unit was running to make the bootable SD card.
[MTCB Software Development] Alxandr:
https://xdaforums.com/showpost.php?p=69374440&postcount=869 not that I can find. I downloaded the OS from that post to try to unbrick it.
[MTCB Software Development] typos1:
That post is misleading - it says about putting the SD card in AND a USB drive, forget it, go to the link in that post and follow those instructions, ie use the firmware that the device was bricked with to make a bootable sd card.

Hi All, sorry I haven't had time yet to read all 1000+ posts in this thread. Wonder if you can answer a simple question - I have a pumpkin android 5.1 unit with 1GB ram. I've done my research and it's capable of running this ROM. My question is - is this rom (or any other) significantly faster than the factory rom? I have a world of frustrations navigating between apps, launching apps can take minutes etc.

Thanks
[MTCB Software Development] typos1:
You need either an upgrade to 2Gb RAM (3 threads on this and/or to install a ROM with MicroG or OpenGapps.

I bought a 4.4.4 Joying headunit last year, will this work on it? It's the 7in one with the volume knob and buttons to the left of the screen. If so, will I be able to use android auto with this as if it were a true Android Auto unit?
[MTCB Software Development] pcmender2005:
Is it a MTCB rk3188?
[MTCB Software Development] imranh101:
Pretty sure it IS an RK3188, not sure on the MTCB though, how can one check? I went to the product page for the one I bought and they have since updated the page to show their newer Lollipop version, so I can't check there
[MTCB Software Development] pcmender2005:
Go into settings then about and see what MCU you have if it's a MTCB
[MTCB Software Development] typos1:
As the first post says, you can use it on any MTCB or MTCC head unit the uses an RK3188 processor, so you need to look at your settings/about device screen and if it says "MTCB" or "MTCC" and RK3188 then you can use it.
[MTCB Software Development] imranh101:
Checked and it's definitely MTCB and RK3188 :) So is there a way I can use the headunit as if it were a real Android Auto unit once I do the upgrade? I know about the Android Auto app but can I then connect my phone to it like a real unit?

Thanks!
[MTCB Software Development] typos1:
You can, AFAIK all you have to do is install the app and connect your phone.

Hello Malaysk, how could i change the color of the keys with your Firmware? Since i updated my MCU keycolor is white again and i cannot find any menu nor setting to change the color in the rom.

thx for your support!

[MTCB Software Development] typos1:
Turn them on in factory settings and reboot 5 times, the Element app should appear, if not, just select the colour from factory settings.

You can go to 4.4.4 Malaysk, i downgraded from original 5.1 without any troubles on my MTCB 3188, with the result of satisfying speed... ( ok, 2 Gigs of Ram would bring it to the top...) but it IS usable and way much better (5 times) then the original L ?
[MTCB Software Development] typos1:
No it is not risky, the SoM can take 4.4.2, 4.4.4. and 5.1.1.

Have you tried [MENTION=6041319]dsa8310[/MENTION]'s microG and openGapps L ? Its much faster because of lightweight google apps.

PPP Widget developer here.

PPP Widget 2/3 doesn't rely on kernel drivers since kernel module loading is disabled since Android 4.3

Consequently, the pppd program can't be used either because it needs those serial drivers.

PPP Widget 2/3 uses the VPN API to create a controllable network interface on the user level (the only way to do that AFAIK) and routes all traffic to/from USB through it.

The problem in this case and annother reported at the PPP Widget forum is that this ROM somehow fails to setup the VPN interface correctly. You should not see errors like these:

05-23 09:03:15.225 D/ConnectivityService(452): Adding iface tun0 to network 100

Hello, I have an eonon g2110f rk3188 which I have updated with

update_5_1_1_FUSE_800X480_RK3188_04_MAL_12_09_2016

The problem is that after the updating the leds of the bottons turn on but the display remains black. This happens even when I entry in the recovery.

Can anyone can tell me how to solve the problem in order to get back to the firmware kitkat 4.4 which I have already the files? Thanks
[MTCB Software Development] typos1:
You dont have an "eonon g2110f", Eonon are sellers only, look in settings/about device, the letters after "MTCB" or "MTCC" will tell you what unit you have.

Either flash KK "blind" by going into recovery and turning the knob the appropriate number of times to install KK and press it, or use the SD firmware tool to recover your unit.
[MTCB Software Development] antonyo17:
Thanks for your answer.

I installed this firmware on the radio of my car model eonon g2110f S07.

I can't enter in the settings to see what unit I have because the display remains black.

Maybe the only problem is that I did not install the right MCU.

If you can tell me the link to download the correct files and also the link to download the SD firmware tool.

Thanks
[MTCB Software Development] typos1:
Yes I realise you cant find out the unit you have at the moment.

SD firmware is here:

"The correct files" are whatever ROM you want to flash, you said 4.4.4. so I would try blind flashing that first, personally.

Actually there is really no option to change the light color of the headunit leds. Neither in the factory settings (with code) nor in systemsetings through android.

Most units have RGB LEDs but not all, its more common for custom fit units that fit specific cars not to have them (because they normally just have LEDs that match the LEDs in the dash) and more usual for universal ones like yours have them (because they ll fit in any car so the dash lights could be any colour).

But if the option doesnt appear then you probably just dont have them I m afraid.

EDIT: just gone back through your post and it seems that you did have them I think, just that theyve disappeared with Malaysk's ROM is that right ?
[MTCB Software Development] ricanxd:
I believe the solution, which is what I had to do as well, is to go into factory settings and change the RGB settings to different colors. Save and reboot each time, takes about 2-4 changes and reboots for the element setting to appear in Android settings. (If this is the issue you are having). Hope that helped.
[MTCB Software Development] moetheone:
Yes, right! I was able to change the led color before i switched over to Malaysk Rom. It kept the setted color, but when i updated my MCU the color fell back to white.

[MTCB Software Development] typos1:
I ve heard of the element app disappearing from a custom rom before but the strange thing is that the rgb option doesn't appear in factory settings. I already said this and told you the password and you said it isn't there. I get the impression that you don't actually know what factory settings are ?? Unless of course you updated to an older mcu.
[MTCB Software Development] hans109h:
It doesn't matter. Change from RGB to red or blue, then reboot and see if you have a new settings menu option. If not go back to factory settings and change back to RGB and reboot. Keep trying.
[MTCB Software Development] moetheone:
finally... it worked. I did not find the elements app but was able to switch "LED" in factory settings to another color ("R"). This was showing "RGB" wich actually means white color.

[MTCB Software Development] typos1:
Did you use the "export" button before you updated ? It sounds like you didnt (export saves all your MCU settings and flashes them along with the MCU) your ll have to go into factory settings and reset everything, if you didnt note what radio tuner you had before you updated you ll have to go through each one til you find one that works (after settings radio area to "USA".
[MTCB Software Development] undrwater:
I reverted to 2.78, got the radio working, went back into factory settings, and hit export. Wipe / Flashed the mcu you provided, it read the mcu.cfg, but no radio regardless of selection (including the one that worked for 2.78). I reverted back to 2.78 again, and was listening to radio.

I can only conclude that some of the later versions of mcu are not compatible with the early units.

Hi Folks,

i've been attempted to flash Malaysk ROM on my NewsMy NU3001 (2GB version, Screen and android box are 2 separated components) which is supposed to be MTCB.

When i entered TWRP Recovery (in the car android box connected to Head Unit), it didn't propose to flash system partion but it proposed only boot and recovery partitions.

Therefore i've decided to do so with RKBatch Tool v1.8 with PC (android box connected to PC through USB <--->miniUSB), and device recognized...firmware uploaded...firmware checked....flash successful....so far so good.

In the procedure, it says that you need to wipe data and cache partitions....However, when i unplugged and re-plugged the usb cable from pc, the green light indicator switched ON showing the device is ON but no way of getting recogized by PC...So i thought plug-in it to the Head Unit in the car might show Recovery or any options....But Head Unit screen is black as well.

So, i end up by a Hard Bricked device !

I red the procedure of unbricking, bootable SD with stock firmware.... I think i'm gonna go for it but in the meantime if you have any suggestion it will be much appreciated.

So, owners of Newsmy NU3001, you're warned.

Thanks,

KR

[MTCB Software Development] typos1:
Malaysk's ROM is ONLY compatible with MTCB/C units - your Newmay unit definitely is NOT "supposed to be MTCB" - its an ENTIRELY separate device and not compatible in ANY WAY.

So flashing Malaysk's ROM on your entirely different unit will never work, lets hope you havent killed your it completely.

As it is not an MTCB/C unit for help with unbricking it you need the Newsmy NU3001 forum, not this one.

I dont think NU3001 owners need warning that they should not flash software from a totally different device onto their Newsmy - most of them will know that already.
