install LE on DEAD A95X MAX V81

xfocus29 · April 27, 2020 at 12:40 PM

hello

i did break my box and i want to unbreak it using LE.

this is what i did try and didn't work :

1. flashing LE with different dtb files no one worked i get no video signal. (using the how to install LE tutorial)

2. short pin (sdinADF4-64g not Samsung ) the box after pushing the reset av button the PC detect the USB but it listed as Unknow USB device even if i installed ton of drivers (burning tool drivers rocketship drivers...),the burning tool and androidtool didn't detect the USB because it listed as an unknown USB device.

3. i did try to ssh into the box because after connecting the box to my router via ethernet i can't get the ip of the box and the ip scanner in my PC didn't detect the box, also even if i see yellow light flashing in the ethernet witch mean the ethernet is not working :frowning:

side of the box

finally i did connect with the UART interface with putty serial port here is the log using USB only flashed with CE :

`G12A:BL:0253b8:61aa2d;FEAT:F0F831B0:12020;POC:F;RCY:0;EMMC:0;READ:0;CHK:1F;READ:0;CHK:1F;READ:0;CHK:1F;SD?:20000;USB:8;LOOP:1;EMMC:0;READ:0;CHK:1F;READ:0;CHK:1F;READ:0;CHK:1F;SD?:20000;USB:8;LOOP:2;EMMC:0;READ:0;CHK:1F;READ:0;CHK:1F;READ:0;CHK:1F;SD?:20000;USB:8;LOOP:3;EMMC:0;READ:0;CHK:1F;READ:0;CHK:1F;READ:0;CHK:1F;SD?:20000;USB:8;LOOP:4;EMMC:0;READ:0;CHK:1F;READ:0;CHK:1F;READ:0;CHK:1F;SD?:20000;USB:8;LOOP:5;EMMC:0;READ:0;CHK:1F;READ:0;CHK:1F;READ:0;CHK:1F;SD?:20000;USB:8;LOOP:6;EMMC:0;READ:0;CHK:1F;READ:0;CHK:1F;READ:0;CHK:1F;SD?:20000;USB:8;`

and here is the log from putty if i use an SD card only flashed with CE:

`¦G12A:BL:0253b8:61aa2d;FEAT:F0F831B0:12020;POC:F;RCY:0;EMMC:0;READ:0;CHK:1F;READ:0;CHK:1F;READ:0;CHK:1F;SD?:0;USB:8;LOOP:1;EMMC:0;READ:0;CHK:1F;READ:0;CHK:1F;READ:0;CHK:1F;SD?:0;USB:8;OO¦¦¦¦EMMC:0;READ:0;KZK:1G;READ:0;CHK:1F;S\Q¦s¦CHK:1F;SD?:0;USB:8;LOOP:3;EMMC:0;READ:0;CHK:1F;READ:0;CHK:1F;READ:0;CHK:1F;SD?:0;USB:8;LOOP:4;EMMC:0;READ:0;CHK:1F;S¦]C¦¦¦CHK:1F;Su]¦¦{CHK:1F;SD?:0;USB:8;`

i think i have this loop because the update deleted the bootloader

because if i flash the sd card with wind 32 imager with this boot image A95XMAX_boot.img from the google drive link:

A95XMAX_boot.img - Google Drive

i get this Log :

The "G12A:BL:0253b8:61aa2d;FEAT:F0F831B0:12020;POC:F;RCY:0;EMMC:0" stuff means no bootloader on eMMC. It's actually a better position to be in than having the wrong bootloader (as then you're in pin-shorting territory). If you put A95XMAX_boot.img on an SD card it will boot from the card and start looking for something to boot. If the u-boot environment contains the usual Amlogic bsp garbage it will look for some "autoscript" files or boot.ini or boot.scr .. so I would start with putting LibreELEC-AMLG12.arm-9.80.0-box.img.gz on a USB stick, setting a dtb name in uEnv.ini - pick another G12A device like X96max or U200. If you're lucky it will find the USB and boot, and tthe UART will then give you access to an OS and console where you have more tools to play with. I suck at figuring out all the sector counts, but as a minimum you can then "dd" the A95XMAX_boot.img back to the emmc device, and then you can probably run LE or other distro's from an SD card.

xfocus29 · April 27, 2020 at 1:59 PM

you mean i need to copy the A95XMAX_boot.img to the SD card plus the LibreELEC-AMLG12.arm-9.80.0-box.img and create some uEnv.ini?

but what to put inside it do you have template?

thank you for your help.

**chewitt** · April 27, 2020 at 2:04 PM Official Post

put the A95MAX_boot.img on SD card, use any SD/USB writing app (even ours, you can drag/drop any .img file no the GUI and we'll use it.

put the AMLG12 on a USB stick.

If you're lucky it will boot u-boot from SD and then search/find the LE boot files on the USB.

xfocus29 · April 27, 2020 at 2:43 PM

i flashed the A95MAX_boot.img on SD card, then i copy past the AMLG12 on a USB stick.

so the USB contain only one file AMLG12 image.

but still i get this error :

as you can see it detect the USB i inserted but it suck with this error

I said "write the image to USB" e.g. same as you wrote the other image to SD card, not "copy paste the file" so that's why it's not doing anything. Note that once the image is written and the image is mounted, you need to access the USB and edit the uEnv.ini file to set the name of the dtb file to use.

xfocus29 · April 27, 2020 at 3:23 PM

thank you chewitt you are awesome , i did gain access to the console serial

what to do now to recover my box?

if i type update i get InUsbBurn and then i connect the box via A to A usb cable to the PC but still i get nothing in the amlogic burning tool or androidtool no connection.

how to install what is in the usb via this console?

**chewitt** · April 28, 2020 at 7:49 AM Official Post

If you're at the LE serial console "emmctool" will tell you which is the /dev/device for emmc, so connect ethernet and scp the A95X .img to /storage and then write u-boot to emmc with "dd if=A95MAX_boot.img of=/dev/mmcblkX bs=1M" .. this should make the box bootable from emmc again and you free up the SD card for booting some kind of OS image (LE, Armbian, etc.).

What OS do you want to restore to emmc? .. and if you already have some kind of files, what are they called and what format are they? (and where did you get them from).

xfocus29 · April 28, 2020 at 3:26 PM

sdc_update- Burning a partition with image file in sdmmc card

before prepare correctly sd card with this tool for writing u-boot to micro sd card Burn Card Maker v2.0.3 - FreakTab

after preparing card copy also *.img and if i remember correctly you must change img string pointing to *.img file in ini file on prepared micro sd card.

some info in this article Download Amlogic Burn Card Maker and How to use it

xfocus29 · April 28, 2020 at 4:23 PM

i can't use the sd card because is used to boot the system with ,

if i use the sd card prepared with burn maker tool that contain *.img, the boox will not boot ...

it will boot only if preprare the sd card with A95XMAX_boot.img file.

because i don't have a bootloader inside my BOX.

usb_burn- Burning with amlogic format package in usb

but prepare usb with "burn card maker" not with dd comand , preparing pendrive usb or sd card with dd command it is also possible but requaire some additional steps

Linux + windows instructions how to do that here:

How to Create a Bootable Recovery SD Card for Amlogic TV Boxes

xfocus29 · April 28, 2020 at 5:48 PM

using the usb_burn or usb_update will trigger the update or burning from the USB dev number 0, but my USB is in dev number 1.

how to force the usb_burn to search inside dev 1 instead of auto selecting USB 0?

P.S : the USB 0 device is the port for adding HDD or SSD (i don't have SSD or HDD).

Swap things around then. Write the A95XMAX_boot.img to USB and boot from it, and put the restore files on the SD card.

xfocus29 · April 29, 2020 at 11:20 AM

if i swap the device don't boot.

stpf99 · April 29, 2020 at 12:16 PM

try to restore oryginal firmware for that box not only u-boot by preparing micro sd card with firmware from vendor, use for that Burn Card Maker v2.0.3 - FreakTab

proces is automatic, after that you can combine with other systems...

xfocus29 · April 29, 2020 at 3:43 PM

i did try that but it don't boot because i don't have bootloader inside the box

stpf99 · April 29, 2020 at 6:47 PM

Maybe on Linux your box will be properly recognized with short pin method as amlogic in lsusb, for burning IMG user this tool

GitHub - Stane1983/aml-linux-usb-burn: Linux version of Amlogic USB Burn Tool

install LE on DEAD A95X MAX V81
