Trying to recover MXIII G II S912 TV Box from what looks like corrupted/dead internal memory

I don’t see such a thing , this is how my tool looks and works.

Start CE and copy meson1.dtb to / storage
then run in the ssh terminal:

dd if=/storage/meson1.dtb of=/dev/dtb

meson1.dtb (86 KB)

Oh true, my bad - thinking of different device. Sorry
Then I guess what you need is recovery.img and / or boot.img for your device to flash with adb. There must be a way to extract those from the .img you already have, I just don’t know it off-hand.

Did:
scp ~/Downloads/meson1.dtb root@192.168.1.42:/storage
And got:
meson1.dtb 100% 86KB 4.2MB/s 00:00
Did:
ssh root@192.168.1.42
Did:
dd if=/storage/meson1.dtb of=/dev/dtb
And got:
172+0 records in
172+0 records out
88064 bytes (86.0KB) copied, 0.001018 seconds, 82.5MB/s

What do I do next?Should I try again with the Burn Card Maker and your .ini?:slight_smile:

Yes, repeat the OTA update.

I did that and I still get this :

I unpacked the contents of the both images (update_MXIII-GII_rv109.img, update_MXIII-GII_rv112.img) and found that the files _aml_dtb.PARTITION and _aml_dtb.VERIFY are missing. Thus these images are not suitable for the OTA update. You need a full-install image.

I just noticed that in this case dtb file must be written to the partition “reserved”,sorry, my mistake.

dd if=/storage/meson1.dtb of=/dev/reserved

It seems to me that the fact that you are getting a low quality picture for the Android robot points to the fact that the images you are using are not right for your box and you probably have the wrong dtb.img. I have personally never seen such a boot image in greyscale before.

Just a thought.

Thanks for sticking around are trying to figure out what it is :slight_smile:

So I did :
dd if=/storage/meson1.dtb of=/dev/reserved
And I got :
172+0 records in
172+0 records out
88064 bytes (86.0KB) copied, 0.518800 seconds, 165.8KB/s

I still get the android with the X thing unfortunately.

About the image, I will try to look for some more , or maybe I could pull those files from a similar firmware or something, but I saw a lot of people on freaktab saying that this firmware worked for them:

Vendor links the firmwares#28:

These are the links they posted:

https://mega.nz/#!j1wTURCQ!H6pLEGCtk-s0bMZ6jDU7JFH7EJgFyMprwkkhP9heTrk
https://mega.nz/#!D1IhnRBS!bwov8ZBpMjjRv2qTGq_3Ofs3kxGo2GTyHZihI8vxsng

I also saw people on freaktab saying that this custom ROM below works for their MXIII GII S912:

Thread where someone says it works for the box#248:

Again#166:

Custom ROM Thread: https://web.archive.org/web/20170711123457/http://freaktab.com/forum/tv-player-support/beelink-aa/beelink-android-tv-box/gt1/firmware-roms-tools-cg/611261-rom-beelink-gt1-alfawise-s92-superceleron-v8c-rom

Custom ROM Download: http://freak-tab.de/luis/Beelink/SCV8C-GT1.zip

I will download and try to install these via the Burn Card Maker method and then come back.

Edit1: I tried the custom and and saw a blue background a droid and a link to freaktab.com and then it went back to the droid with a X sign.
Edit2: I tried formatting the card as FAT32 then copying the contents of sd_MXIII-GII_rv109.zip to the card but it won’t boot, maybe I need to dd something there?;however TWRP worked with just formatting as FAT32 and copying and renaming the image to recovery.img without dding anything.
Edit3: I tried formatting the card as FAT32 then copying the SD firmware again and this time it booted to a black screen.

Post#225: Here you can see a guy trying to flash a custom ROM getting this image.

Then here: http://freaktab.com/forum/tv-player-support/amlogic-based-tv-players/s912/611106-mxiii-g-ii-tv-box-amlogic-s912-octa-core/page16

Post#226:You can see the same guy saying that it worked with the same image but with a different card.
Also Post#236 getting the same image with the stock firmware.

As said previously you will require the FULL original image to restore properly and not an upgrade image.

If I ssh intro CoreELEC and do:
cd /dev

So I think all the files I dd are going to the CoreELEC SD card not into the internal memory.

Is there any way to make the box use the SD card as internal memory or somehow install android on the SD card?

  • No. They are eMMC partitions.
  • Yes, but it is very time-consuming. Please keep in mind, we are not in the Android forum. :slight_smile:

If I boot from another card with CoreELEC on it and ssh cd /dev then ls the bootloader,dtb,reserved folders are no longer there.

what I have noticed so far - partition “boot” is missing. Please type the following command and show the result

ls /dev | grep boot

Furthermore, a complete boot log would be appropriate. Please read how to establish a uart connection between the box and the PC.

Hello,
I have exactly the same problem as Bojan but on different device.
Have Sunvell T95V Pro (S912, 2gb/16gb)
It’s bricked, just power led, no signal, no recovery, nothing.
USB burning tool don’t recognize the box, unless I short two pins on nand. Then I tried to flash all the roms I can find, but always the error at 7%-formatting…
Tried with the SD card method but also without success. Box won’t boot from SD card, unless I short two pins on nand. Have tried with reset button first, but nothing happens.
When shorting pins, get android robot and “upgrading” but hangs forever at the beginning, same like Bojan.
Then I tried with CoreElec, burn card with s912 image, but all the same, won’t boot unless shorting pins. Then it boots perfectly and everything works very well.
I tried also “installtointernal”, it start’s but hangs on “system-formatting”. Think that EMMC is busted, not corrupted or blank but dead, because it refuses writing on any way.
So, is there any way to force the box to boot from SD card when the emmc is broken?
Bojan’s case is little bit different than mine. I read on this theme that solution was to write “aml_sdc_burn.UBOOT” from working stock image to SD card with coreelec, but problem is that my box won’t bot with any stock upgradable firmware from SD card without shorting pins.
When coreelec is loaded it works flawlessly, but it’s very annoying to shorting pins every time I gonna watch something…
Any help?

Just to say that I managed to solve the problem.
First burn CoreElec to SD card, then use Amlogic Boot card maker with u-boot.bin.sd.bin from stock firmware, just UNTICK option to format.
When done, put SD card to box and boot straight away to CoreElec, without shorting pins.
Now everything is working excellent.

many thanks i had a similar problem and you solution worked fine for me :+1:

Hello Nebojsa!
I know it’s been a long time since your post, but I’m trying to revive a T95vPro like yours and I run into exactly the same problem with the addition that I don’t have the original firmware nor can I find it anywhere. All the links I find to this firmware are down.
If you still have it and it’s possible for you to share it in some way, I would appreciate so much.
Thank you in advance
