Interesting. Not to point the finger or anything, but perhaps something went wrong with the flash procedure? USB cable or something? Admittedly I haven't been following this that closely so I don't know how many people have bricked their boxes.

I use a USB 3.0 cable and a USB 3.0 port to flash my boxes and run USB Burning Tool 2.0.8.

I flashed my box the same way I did my M8S Mini II: load firmware, press start, plug one end of USB cable into PC, press and hold the reset button and plug the USB cable into the box. I normally release the reset button once all of the windows notification beeps stop.

I've flashed the firmware 3 times using the above method with no issues; once to 0919, then back to 0815 because I wasn't happy with 0919, then finally to magendanz rom.

I haven't flashed yet. Just made a factory reset. It seems to be better than before now. Bought this box because of the roms but now looks like risky

Sorry to say, but i had the same code (now i remember) and it's a SEC713 witch is in the faulty area according to freaktab....but really strange that no brick happened....there was also a other guy with Fw0815 and SEC713 who had no problems flashing the box maybe this combination is risk free

Guest knows more i'm sure

Actually, I have three boxes and none are from the affected batches, so I'm guessing like the rest of you.

I can't find the WIFI Settings in LibreELEC.
The device-tree is from:

http://wrxtasy.libreelec.tv/MECOOL/dtb.img

is it not supported or is there a way to get it work?

[hansdampf]

Under chip type it says AJNB4R...is that what you're looking for?

Could someone successfully mirror the phone/tablet to the Mecool M8s Pro+?? I can just share pictures oder videos but not mirror the whole screen .....is there a extra app to for mirroring? i have a Samsung A3 2016 with Marshmallow

@rahzel
what is the chip the eMMC app mentions? can you tell us? in my case it's KLMAG1JENB what means the bad SEC713

edit: after googling this code, it seems to be a Samsung chip. Aren't the Samsung chips suspected to be the faulty batch? Or is it only certain Samsung chips?

My box runs fairly well running magendanz Nexus rom. No lockups yet. My only issue is the WiFi seems to drop for a second the odd time, but I suspect that's a HW issue.

But yeah, I was able to flash to magendanz rom, as well as GB's 0919 firmware using USB Burning Tool without any issues.

Do you have properly SD card with Libreelec on it? When you do "reboot update" Libreelec from SD Card must boot up.

I just check everything.

It was my fault GRRRR. I used a wrong image "LibreELEC-S905.arm-8.2-8.1.10-C2.img" insted of "LibreELEC-S905.arm-8.2-8.1.10.img.gz".

now it works fine. Thx for your support

[dstojic]

Thx for the answer.
I've tried but it only boot into the Adroid Recovery not from the SD-Card

[stlab]

With SD card in slot in Terminal app you should type reboot update and then box reboot Libreelec. If you want reboot in Android you should pick Reboot from internal from shutdown menu on Libreelec.

I had exactly the same problems with my M8s Pro+(Gearbest, FW:0815, sec 713)....it might be possible for u to look witch emmc u have inside? there is a app in the play store called "eMMC" to look for.... i'm still afraid to update to FW:0919 and to brick it.

And could someone successfully mirror the phone/tablet to the Mecool M8s Pro+?? I can just share pictures oder videos but not mirror the whole screen .....is there a extra app to for mirroring? i have a Samsung A3 2016 with Marshmallow

The app didn't give me any relevant info from what I can see. But thanks for the tip.

Like I said, I went ahead and updated my box and thankfully it went smooth. However the firmware itself was... meh. It felt smoother but they removed the status/navigation bar option in the display settings. The volume controls are linked. And play store was the Android TV version and the regular version downloaded from apkmirror didn't work.

I decided to flash to magendanz nexus rom and it runs just as smooth, if not smoother, and magendanz's rom has the status/nav bar option still there. So far I'm fairly happy with my box now.

Big thanks to megendanz for his work.

BTW, I was noticing in the u-boot usage doc that the write command automatically skips bad blocks. That would explain what we're seeing with those partial firmware writes on the affected boxes. If the same "bad blocks" are always skipped, they might retain their original contents from the factory firmware. Then only reflashing the original firmware would restore their integrity.

gxm_q20x u-boot Usage:
store store init flag
store read name addr off|partition size
        read 'size' bytes starting at offset 'off'
        to/from memory address 'addr', skipping bad blocks.
store write name addr off|partition size
        write 'size' bytes starting at offset 'off'
        to/from memory address 'addr', skipping bad blocks.
store rom_write add off size.
        write uboot to the boot device
store erase boot/data:
        erase the area which is uboot or data
store erase partition <partition_name>:
        erase the area which partition in u-boot
store erase dtb
store erase key
store disprotect key
store rom_protect on/off
store scrub off|partition size
        scrub the area from offset and size
store dtb iread/read/write addr <size>
        read/write dtb, size is optional
store key read/write addr <size>
        read/write key, size is optional
store mbr addr
        update mbr/partition table by dtb

Hi,
Does anyone know the distribution of pins in the AV socket?
Where is GND located?

[hansdampf]

So I received my box from gearb and the firmware it came with was 0815. There is a reset button.
The box hasn't froze up on me but it seems quite buggy. I have a logitech mouse connected to it, and the mouse cursor is restricted to the top left quarter of the screen. After a while, the overlayed settings menu on the right becomes quite sluggish. Youtube (playstore version) came preinstalled, but it is not listed in the app drawer, only the settings app list, so I can't add a shortcut.

Am I safe to update to firmware 0919, which as I understand it is the latest firmware for this box?
When updating it with USB Burning Tool is it similar to the Mini M8S II and that you load the firmware, press start, press and hold the reset button and plug the box in via USB? If so, does it matter which USB port?

Any help would be appreciated.

EDIT: I took the risk and just went ahead and updated the box (I know I should have probably taken it apart to check the emmc etc.) but I lucked out and it flashed no problem.
The box seems snappier so far but I just installed it.

The only issue I have with this firmware is they seemed to have removed the option to show the status bar. Is there anyway to get that back with this firmware?
edit2: Also annoying is the sound sliders are linked to each other. I can't set the media volume to max and other volumes low like I usually do.
