Hello

Tv box: mxqpor 4k s905x 2/16 p212

I used the script to install armbian on internal memory an and works partially because tv box boot from internal memory but without sd card the system does not start

I deleted all files from the boot partition from desktop environment and now my tv box freez on amilogic logo.

i have tried to rum armbian from android recovery using ext> sdcard> aml_autostart script but i get error

cant find / misc!
sd/block/mmcblk0 to /sdcard  read only

is there a way to fix it or do i need flash firmware?

Moved to tv boxes

hello

 

now I definitely broke the box

 

I used gpatred from os on sd card to clean internal memory
but now i get only red light and tvbox doesn't want boot: /
I assume that it was not the best idea and I just started to get to know that the world of arm works a bit differently than a normal PC

I tried to use amilogic burning tool
after connecting the usb, I see: connected success.
but i stop on 1-2% and it throw error:
0x10103005 romcode / initialized ddr / download bufer read data item failed

I read that it may be the fault of a weak cable (I will check if I have a different cabel)

on linux I tried aml-flash-tool but when i start ./aml-flash i get Board is in secure mode

I also saw that i can short pins to bypass nand / emmc memory but I don't know which pins.
my nand / emmc chip is: samsung klmag2geac-b002

on other threads I read that after the nand memory format and need to use external programator to flash uboot?

is there a chance to do something about it?

my tv box mxq pro 4k s905x 2/16 p212
board: hnt-s905x v1.0 170519

Since you have an amlogic based box, you need to locate an original android firmware for the box and use the amlogic burning tool to restore the box to a known good state running android.

I tried :
-many different img
-aml burning tool (1% always)
-sd card burner

 

this is output from uart to usb:

GXL:BL1:9ac50e:a1974b;FEAT:BDFC31BC;POC:3;RCY:0;EMMC:0;READ:0;CHK:AA;SD:800;USB:8;
LOOP:1;EMMC:0;READ:0;CHK:AA;SD:800;USB:8;
LOOP:2;EMMC:0;READ:0;CHK:AA;SD:800;USB:8;

mayby someone have img for this device?
and can tell my how to fix this?

someone use librelec forum i cant add thread or ask anybody there? 

@N3bi2 - you may try to dd this (gunzipped): https://github.com/hexdump0815/u-boot-misc/releases/download/200718-01/boot-amlogic_gxb_atf-aarch64-serial.dd.gz to the beginning of an sd card - this should at least give you a working and booting mainline u-boot from sd card ...

Hi 

 

How to burn this on sdcard?

 

ok i found  

 

the boot-xyz.dd file should be written (after a gunzip of course) via "dd if=boot-xyz.dd of=/dev/target-disk bs=512 seek=1 skip=1 status=progress"

i tried but noting hapend.

this should work actually as your boot block sees and reads from the sd card (SD:0;READ:0) ... there is one thing which might explain it: encrypted boot loader - very few boxes have it (for gxl for instance the mi box, s905x2 the a95xf2 for instance - or was it a95xf3 maybe ...) - in that case the only chance you have is trying to find some original firmware for the box with the proper signing and encryption - everything else will not work ... i think the reason why it ended up in this state is that someone installed another unsigned/not encrypted image on it ...

Hi

 

it was probably me

I tried to use linux on it and found armbian and  i wanted to install it on internal memory using install script and it work until I formatted the memory: /

 

its sounds not good because is hard to find stock rom for it

 

you think this can help some how?

i don't think that this will help - your only chance is to search for potentially fitting stock images and try them until one works ... otherwise you have a nice little s905x doorstop only ...
