RK3518-D4-V1.0

[Roman Caletka]

hello everyone!

I bought this tv box..https://www.aliexpress.com/item/1005009346784515.html?spm=a2g0o.order_list.order_list_main.11.79e81802pgNRxu

but after starting it was not possible to log in to googleplay even though I had a connection via wifi or ethernet. the preinstalled version for applications was Aptoide TV..through it I wanted to update all applications (youtube, netflix, etc.) I managed to do that but no application could be started. the original file manager did not show the internal memory or USB disk or SD card until I managed to download ES file manager through aptoide and it showed my flash disk I installed HW info device and there I found out that it was an RK3528 chip.
so I wanted to flash the firmware and I used a rom image for H96max with the same parameters.
the firmware upgrade went OK but the device is dead. I can't find the correct firmware.
I'm attaching a photo--- maybe someone will recognize the board and identify which rom-img should be correct.
the seller can't help me in any way.

HI, It looks like you have an RK3518 chip from your photo, and not the 3528? Or was that a typo? In any case I also bought a box from AliExpress. It looks similar to mine with the 3518 chip. If there is a way to extract the ROM Image from my box I can maybe upload it for you somewhere?

Hey there,

 

Title:
Need compatible firmware / loader for XR8223518K-V1.0 (RK3518) TV box

Message:
Hi, I’m trying to recover a TV box with this exact mainboard:

Board code: XR8223518K-V1.0
SoC: Rockchip RK3518

Symptoms:

device only shows blue LED

no HDMI output

device can still enter MASKROM / Rockusb mode

What I already tested:

RKDevTool detects “Found One MASKROM Device”

using my current MiniLoaderAll.bin + ExportImage.img fails with:
“Download boot fail. Please check DDR.”

So I believe I need:

the exact stock firmware for this board
or

a compatible RK3518 MiniLoaderAll.bin / loader for this exact board / DDR configuration

If anyone has firmware, loader, dump, or files for XR8223518K-V1.0, I would really appreciate it.

Thanks.

hi. I gave up a long time ago. but now I found the board in the closet and decided to look again. I made a typo in the marking. I have rk3518. can you upload your firmware backup to google drive. or whatever suits you.
