Hello guys I hope you can help me. I have a car GPS (Unfortunately I am not allowed to publish links here but is a regular chinnese dash cam with GPS). It comes with a "board" cm84 dvp v2.1. It was working fine until one day I turned it off without knowing it was doing an Android upgrade on the back and after that it started looping while boot. So it shows the splash screen then it says that Android is upgrading - Upgrade 1 of 1 and then it just restart again. My guess is that part of the upgrades files were stored in cache and they now don't allow the GPS to boot. I know normally entering the Recovery boot via Down volume + power button I can clear cahe and even factory reset it, but the thing with this device is that it doesn't have any volume button, the only button it has is the power one so I have no idea how to access that option. Does anyone know how I can do that? Also, just in case, when I plug the device via USB to my Windows 10 laptop I see 2 units (D: and F on device manager but not on Windows Explorer.... in case there is no way to access the recovery boot because of not having a down volume button... is there any way I can just delete the cache folder content from Windows using any software? Thanks a lot in advance for any hand you can give me. I tried Coolmuster Android Eraser which detects an Unknown Android device but asks it to configure it to accept USB debugging which clearly I can't do.
Any solution?
Hello,
I am facing same issue with my device. Did you manage to find any solution to this problem.
Hi all,
first post in this section, so be nice I have a very recent build Xtrons TQ700L unit that i have managed to soft(?) brick after rooting and removing a factory app ("Easy Connect"). On boot I get the initial logo, then after a long time a black screen that goes nowhere. I'm looking for advice on the best strategy to recover/rebuild it.
Hardware details...
build number:
rk3399-userdebug 10 QQ2A.200305.004.A1 eng.hct2.20200521.120545 test-keys
MCU version:
MTCE_GS_V3.53_3
As i understand it i have an "MTCE, GS" MCU and can ONLY flash MCU updates from the GS manufacturer. The MCU is probably not the problem here though.
I have a PX6, Android 10 build date of 20200521. Am I correct in saying i can flash any android 10 ROM designed for the PX6 that is newer than this date? Are the only differences between manufacturers cosmetic, like the nice launcher Xtrons supplies?
When i look on Yandex (https://yadi.sk/d/umCvHqCDzHccr), there is no PX6/Android 10 firmware at all from "GS", but there is from "HCT". Should i be looking at flashing the HCT/PX6/Android 10 firmware date 20200612 from the recovery menu? I can get to recovery easily enough by holding, then double clicking the reset button - i just dont know whether i should be flashing part of or the whole of the above package to fix my brick.
thanks.
So in case this helps anyone else, it was an easy fix. Baby steps below.
- grab the latest "Android 10", "PX6/RK3399" factory ROM either from threads here, or from Yandex. I found HA3_RK3399_10.0_ota(20200706).zip here on XDA.
- unzip the outer layer ZIP file and copy the inner "update.zip" to a micro SD card. The stock recovery systems dont allow any selection of ROM file names, so it must be update.zip.
- put the SD card in the "GPS" SD slot.
- with the unit on, reboot to recovery. My way was using a nail to hold the reset button in until the touch button lights began the flash, then quickly release and double click the reset again.
- in recovery, menu items can be scrolled through by either clicking the reset button, or (in my case) touching anywhere on the screen (easier).
- push and hold the rest button (or screen) to select the item.
- do a "wipe data/factory reset" (i guess) to be sure of cleaning out the old mess.
- then do "Apply update from SD card". it should automatically find the update.zip and apply it to all partitions.
- select reboot. Done.
The ROM i used was a "HA" branded generic ROM, so it didnt have the same launcher as my original "GS" (Xtrons) branded ROM. Xtrons wouldn't supply me with their stock ROM when i asked. The generic one was a little better anyway, since it has a stack of boot animations to choose from, whereas the Xtrons one only had the Xtrons logo. It also doesnt have the Easy Connect app, which is what I was trying to remove in the first place!
Additionally, i was able to obtain root easily by using the wifi ADB method here.
I did the same thing. Stupid app kept opening.
I don't have a micro sd card slot, hope it works with usb stick. Don't have one at the moment to try.
Same as yours.
Also, entering recovery mode you..
Hold reset button for 10 sec, release and immediately press it once.
I have a dicola px6 mtce
I'll update if i get it working.
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.

I've got that. But the hard thing is that i will not see this manipulation... I have to do that blindly. Risky stuff, right?
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
