Eonon GA6164F - Recovering from no Boot/Brick - MTCD - RK3188 - MTCD_KLD

Here are my notes regarding the Eonon GA6164F and recovering from a black screen, cant boot, cant get into recovery.
Thanks to all the members and information on this site who i was able to piece together to come up with this solution.
I still dont know if my assumptions are totally correct, (please comment if i need to learn more) .

Back Story : My device was shipped with a Dec 2016 Android 5.1.1 build, and my steering wheel keys on my Camry were not all working.
Skip track and Back track were doing the same action, I tried re-learning/mapping in "WheelKeys Study" but nothing fixed it.
I resorted to using Vol - + for volume, Skip forward = skip track, MODE button (underneth) as = skip back.
I contacted Eonon about this, and they gave me a new Android build to try, update.img.
I wasnt able to update using the Settings - About - Software Update. (Error finding file).
I wasnt able to update using the standard recovery options (RES button, power etc.)
I did notice it was looking for dupdate.img.
I renamed my update.img file to dupdate.img and it was able to install via the Settings - About - Software Update.
The device rebooted , installed, then nothing... just a black screen.
I couldnt get any display up no matter what i tried.
After 24 hours or so of testing/trailing etc. I did manage to get it back working.
Im certain it was a bad update file because once i had it working again, i re-applied the update file i was supplied and sure enough, it broke it again.
These are my notes on how i recovered it.

Boot into recovery and restoring on a un-healthy device
----------------------
If cant boot into recovery
Download a Malaysk android build file (you may need to sign up to the hosting server site, and then add to downloads, then you can download to your computer from there)
Create bootable SD card using 'rockchip create upgrade disk tool v1.4'
(Run .exe as admin, dont check 'SD Boot', just leave 'Upgrade Firmware'
(If you cant see your USB drive, check that you have right clicked-Run as Admin in windows on the .exe)
Select Malaysk MTCD dupdate.img file
First post has download links
https://forum.xda-developers.com/android-auto/mtcd-discussion-questions-development/rom-malaysk-roms-mtcd-device-t3385309
Fully power off device (unplug from the back/or remove neg battery from car).
Insert new-bootable SD card into GPS slot
Plug device back in (or reconnect neg. battery cable to car)
- Device will boot into recovery and complain about no update file (thats fine) the Bootable SD card is just to get you into recovery.

Now i am running a 10.8 build, because i was having trouble with the Google services on the latest, and i need to learn more about the 11.4 build and the MicroG stuff that replaces the Google services.
I am still suffering from the steering wheel controls issue, but at this point... i dont care...
I found i am getting a lot of "unable to read file" from the m4a files i have on my SD or USB card/stick and i need to learn more about how to get the steering wheel controls to action "other" music apps, i believe this is to do with the MTCD-Keys stuff, but going from what seemed like a dead device to this point, i want to wait a while before i start playing with it again.
I have added pictures in the thread, but they are linked to a photobucket, so i have also added them as attachments in case that photobucket account ever goes down.

Eonon Issue HELP!!!!
I have a Eonon Radio similar to this unit except it originally had 4.2.2 on it I recently tried to update it to 4.4.4 and mcu 2.81 which worked perfectly until restarting the car overnight. Radio booted into cannot find e:\
I then reverted back to 4.2.2 but I can get to the 4.2.2 recovery mode but every update.img I try to use only puts me into a reboot mode of the KiKat screen Maylay Mod Splash. Anyone out there can help suggest something?
I seem to have a half baked system that I can get into the recovery mode for 4.2.2. but the update.img says it cannot find it in the GPS sd card.

There are no Eonon radios, Eonon sell radios from several different manufacturers, the one in this thread is a Klyde - KLD.
If yours was 4.2.2./4.4.2 and MCU 2.85 then you have an MTCB unit and you need to try in the MTCB forums.

I've downloaded the rockchip create upgrade disk tool v1.4 and ran through your instructions. The HU won't boot off the SD card. Just sits there. If I remove the SD card, it immediately boots into the installed ROM. (I want to downgrade)

Try making a bootable sdcard.

Guys your help pls! My head unit is stuck to the initial logo (Navigation System) and there seems to be nothing I can do to get into recovery to re-install the software. I have tried everything described above, no way to get into recovery with buttons, so I made and SD bootable card with various firmwares but the HU does not seem to read the card (I tried also with a USB stick, with no luck).
Is there anything else I can try to get it to work again?
My HU is a Px3 MTCE KGL 2 GB.
Thanks a lot for your help!!

You shouldnt need to press anything, it should boot from the sdcard as soon as you turn it on. I would read @marchnz's unbricking threads if nothing its working.

Just want to know were I can find an "original" Rom for my Klyde PX5 MTCD unit.
I install Hal9k and it work like a charm but what if I have to send it back to Shenzhen?
Maybe I have to do this so before that I want to get it in original state.

Lol, no one send their unit back to China because it costs too much, its far easier and cheaper to repair it yourself, but there are factory ROMs around if you look, but I wouldnt bother looking unless you need to, cross that bridge (if and) when you come to it as they say.

Now it's a situation I really need that klyde mtcd px5 firmware.
Are there any hints or links?
Thanks ✌?

Yeah loads all over the forums.

tcl android tv firmware

where i can download tcl android tv firmware to flash it with usb

I want to know too, I think there's already TV's with version 9.0 but mine still on 8 I would love to update

I found this about a year ago. I don't have the source, but I remember getting it from a forum where a TCL developer shared the folder. Instructions are inside the folder, you have to translate that. It's still Oreo and I haven't tried by myself, so please be careful and flash it at your own risk. The last update was on July, so I don't know if they are still updating the repository. If you find pie upgrades, share here as well, please.

Instructions are inside the folder, you have to translate that.
Google says the instructions translate to:
"We change the file name to Update.pkg.
We format the pendrive to fat32.
We are installing Update.pkg.
We disconnect the tv from the power supply.
We connect a pendrive.
We hold the power button on the tv (not on the remote control).
We connect the voltage all the time by holding power on tv.
We hold until the update information appears."

I have a TCL 65" TV, purchased about 5 years ago and it was going ok until it wouldn't open YouTube so I did a reset on it with the hope that its memory would be rekindled. Alas, it didnt and now the once operating TV has nothing on it whatsoever ! What changed was it went from a TCL with Australian software on it to a Thompson with (EU) software on it. I can't scan channels of course (different country parameters), I can connect WiFi but not sure if it is working and it is now very slow to respond to remote, basically there is nothing there but I can still get into settings ect. It has a project Name of 65UB6406, Software V8-NT67FO2LF1V614, Chassis NT667EU and a Serial Num 1605DAJ60000600536. Is there any hope for this TV to be resurrected? I haven't been able to find any firmware for the Asia Pacific area for this TV. Cheers

TCL 65P815 firmware update problem and few things

Hi,
My problem is with 65P815. Fabric software was v084, i tried to update to V191 official version from TCL page, but after update and turning off TV, there is nothing shows on screen. I hear only sounds, and remote clicks, menu gone etc.
I search for info, and go back to v083 software, that helped and fixed TV. But now I don't know what to do to fix my TV. Tried to update with factory reset, nothing helped. Any tips how to deal with it ?
Next thing is concerned with soundbar thing, I have LG soundbar, is it possible to control soundbar over TCL's remote ? On my old Samsung TV it worked normally.
Here in TCL I don't see option to choose sound sourec (tv speaker/optical/hdmi), there is no option to mute TV speaker and move sound to soundbar. For now I use 2 remotes, but I want to use only one like in Samsung. I connected soundbar with optical cable to my TV.

Hi there. Trapped into same thing. After flash, I can hear 'bing' when you navigating in menu, backlight is working, but screen still black. Tried to flash V191(Inserted stick to USB2.0 with Update.img and plugged in with power button pressed). But got same thing. Led is blinking during i suppose flashing, but after that - nothing. Can it be somehow reset to stock or whatever?

you have to go back to 0.83
Turn off the TV, plug out the cable. put the drive into usb 2.0, press power button on TV's back and plug in power cord, if led start blinking wait about 10 mins to finish flashing. Sometimes you have to do this twice and TV will be ok.
Write to TCL support about your problem, let them prepare patch

Hmm... I have couple of questions then.
Does that mean v083 firmware didn't published somewhere?
And does that mean that we can't update 65p815 to any new firmware with Android 11?

what was your native FW ?
I tried to update to V191 which is on android 9, and update was failure. There is something wrong with the FW
File upload and sharing. Large file transfers. Free online cloud storage.
Visit this link to download: V8-R51MT02-LF1V083.zip
files.fm
here you can find v0.83
Android 11 is in beta now, we have to wait for official final update

I didn't check my original fware version. I know that was very stupid, but i supposed that just platform is matter.
Thanks for link. Will try this fware. Hope that will help, because i don't like to waste time with support, that usually just redirects to another operator...

it should, try second time if the first will failure

Ok, i just finish downloading and i'll start bring that baby to life. Thanks for help. Will report if suceed.

report it to TCL support to make technical request, and to fix that firmware

Ok. Just flashed twice. God damn, you have been right! All works like charm!
If someone will be as "lucky" as me, steps are next:
1. Load to local pc zip from above.
2. Format flash stick with FAT32 and copy it to root.
3. Insertt stick into USB 2.0 port.
4. Turn off TV power physycally.
5. Press and hold On/Off button on a TV's back and plug TV holding button pressed.
6. Hold for 10 secs, the led in front of TV will start blinking - it is ok.
7. Wait till it will stop blinking and wait some 5 mins after that.
8. Repeat steps 4-7. After TV restart it will show TCL logo and Android welcome screen will appear.

Ok now we should think about how to flash properly new version of FW,
latest official firmware is
https://www.mediacenter.tcl.eu/uploads/common/R51M_Android_P_V191.zip
When I try to flash with it, from menu update/local it works but only first time. When I turn off TV, then screen is black
I found such instruction, what to do after installation
Press the Settings button in the remote control:
Press OK on the icon: Picture.
Then go to the line Advanced settings.
Scroll down to the line: Brightness settings.
Scroll down to the line: Contrast.
With the remote control, do the key sequence: 6 4 2 5
The special menu appears.
Go to the line “Reset All” and press OK.
Go to the line “Reset Shop” and press OK.
Now unplug the main power cord.
Wait for ~2 minutes.
Plug back the main power cord and perform complete installation.

Seems on mine 65P815 by your table, the code should be ST6451D02-3 (code 305), but i have ST6451D02-H (code 283).

I have flashed v272 (img file) from v084 to my 65P815. Flashing went smoothly with no black screen ecountered. v272 works nicely with no problem.

@ancifil said:- "Did you reboot your TV after that?"
Sure I had rebooted it after flashing as I have been using this firmware for about a month.
I remembered flashing it 2 times. The first time was not successful (can't remember due to what). The second time reflash (same as what you did as in post #10) was smooth and without any problem.

jngiag, looks like it should, as for me... Maybe, i shall try 272 one more time.
superfly86, did you try 272?

Btw, one thing. Can you remember, after you had flashed 272 first time and after that launched flash menu, to flash second time, was you able to see menu?

I think it was due to a request to input pin while I was trying to setup live TV. I did not know the pin so I powered it off and reflashed as in post #10. Sorry, I can't remember it exactly.

Your 65P815 with panel ST6451D02-H...... Project ID MUST be 283.
This is your problem with firmware (black screen ) !
So you need to change ID number from 305 to 283.
To modify the project ID, when TV is ‘ON’, with the remote control do the key sequence
0 6 2 5 9 8 .....MENU.... 283.
At the end of the key sequence the TV must reboots alone if the project ID has been understood by the TV. If it doesn’t, update the product with the last software available and try again.
Sometimes several tries can be necessary for successful project ID modification.

You need TV to work back or worry about not to reset TV ?
First try to unplug TV from power socket and after 10-15 min plug back .
If not,you nee to flash PKG file, to boot normal again.

Soft locked my Android TV?

So...
I was dumb enough to play with the developer options hoping to find an option to deactivate adaptive screen resolution. instead i clicked on something and now my tv is kinda soft locked. at first it was stuck in a boot loop, eventually went into recovery mode here and there (see attachment, maybe there are some informations that could help solving the problem) , but i couldn't select/press anything bc this tv only has a power button. Later i found out you can use an USB keyboard to select stuff in recovery mode. So i grabbed my keyboard and waited for the RM screen. but it wouldn't show up. idk why but now its booting "normally", even shows the android logo. but then its just black. eventually the TV turns off and then back on, over and over. i tried every button combination I could find on the whole internet. Nothing seemed to work. One combination got me some hope but that hope disappeared quickly: i unplugged the TV, held the powerbutton, plugged the TV back in, still holding the power button, and waited.
after a short time it showed me a monitor looking like symbol with a gear icon on it and the gear was crossed with a red X. under it it was saying "error". (see attachment) ("Fehler" means "error" it's german)
so here i am. idk how i get it back into recovery mode so i can try that keyboard method.
and since i got that TV from my gramps, I don't have much information about it either. just got the TV and the remote from him.
I just know that it's the TCL 43EP640 respectively 43EP640X1. (Theres a sticker on the back of the TV, see attachment) so yea. I've heard you can update the firmware/software using an USB stick but idk how and i couldn't find any firm-/software for this TV
If you've read to this point and have an answer to my problem: I Love you
