@Sergey Lepeshkin thanks for the quick reply! i ordered it and pulled out the dtb, kernel, ram settings (hope this help building the armbian) https://drive.google.com/drive/folders/19oQF4U7VyI9lDBRBOuTHgxHQBjBO7cAt?usp=drive_link

@Sergey Lepeshkin it's been a while but could this work? it's a ft232rl usb to ttl

(sorry for bad english) this box is heavily locked down i want to install armbian for emuelec on it but no support and no root but luckily it can local update throught sdcard/usb i just want to watch kodi, play emulation games does any one have the android tv firmware for this box? specs ( if needed): 1g ram 4g rom cpu fake allwinner h313 ( high chance is h3 because uses mali 400 mp2 and armv7a i checked on aida64) android 9

specs: hi3798 ram 1g rom 4g sd/usb boot or emmc boot any help appreciated

@Nick A yeah, no progress.

@Nick A I tried it — I installed everything and created a secure boot image, but it doesn’t even attempt to boot from it. It just goes straight back into Android. Any idea what I might be missing?

@Sergey LepeshkinThanks for the clarification. Could you please recommend a specific USB-to-UART (3.3V TTL) adapter model that you know works well with this TV box? A product name or chip (CP2102 / FT232RL / CH340, etc.) would be really helpful.

Hey @Sergey Lepeshkin, i got the cable after 1-2 months now, i tried adb and all of them didn't regonize, only the middle port of the side, but i can't connect to it, it also beeps like theres a connection conflict, any solution? (There is no root on the board i tried using root detector and magisk), any help appreciated EDIT: here are the commands i tried: C:\Users\UX305\Downloads\DUC DANH\6. CODING\ADB\platform-tools-latest-windows\pl atform-tools>adb devices List of devices attached C:\Users\UX305\Downloads\DUC DANH\6.

@Sergey Lepeshkinok

@AndroidNewbie Do you have the image of the box?

@Sergey Lepeshkin thanks for the information.After a while search for soldering shops i didnt have any results, it seems like there is no soldering shop in my city (there are but very far away). I was expecting a alot of them since im in the center. What to do now? EDIT: I tried your modified update.zip, and it regonized it, i clicked the the Settings > device info > local update > mmcblk0 (the sd card with the update file) and it rebooted, after that that, the box didnt update anything 😕

@Sergey LepeshkinThank you, it all make sense now… but could you suggest a uart connector? And every time i boot, do i have to get the uart connected?

@Sergey Lepeshkin i also note that the picture of the tv boxhttps://drive.google.com/drive/folders/1etPmH8ZG4UtPHI3Vf1U9MUHl5_gK_s-E are from diffrent boxes, but the reflash_from_backup.jpg is probalby mine. But i can't access the recovery menu, is there any way?

@Sergey LepeshkinThank you! You made me feel better, i will flash your modified .zip file since i saw 2 partitions on the file manager, that's why Also, i don't have a uart connector and soldering skills, so is running armbian on my atv box impossible???

@Sergey Lepeshkin from the messages, i bought it online and the seller i know him since i bought wires from the shop. I couldnt contact the seller to provide the rom and i think they dont know since they most resell them. Also is it safe to install that file on my box?? Im scared that is going thr brick the box
