Yeah, found out recently that I'm an idiot. Still, much obliged about the ports, I hope it helps somebody else.

Nice its even printed onto the board

You have Allwinner device, not Amlogic, so use appropriate tools and guides - https://androidpctv.com/allwinner-fi...-guide-tv-box/

Hi,

Just acquired an MXQ Pro 4K 5G RK3228H 8GB/128GB, and was hoping to use rkDumper_1.1.1.0 to back-up the eMMC flash, in RockUSB Mode.

Seems that the clever engineers that put this one together, have used a boot loader with no RockUSB Mode implementation, and also seem to have left out the Android Rescue Mode. Just to be fun, and a bit different, they've also left off any identifying PCB markings, and used unmarked chips, save for the eMMC/ RAM chip.

So, my first question might be: how do I get a copy of the eMMC contents?

Undeterred, I've learnt that RockChip SOCs have an inbuilt Maskrom Mode.

My next question is then: where located on my pcb, am I likely to find the requisite eMMC Clk pin, for shorting to ground, and invoking the USB Maskrom Mode? Can this mode be used with any kind of 'dumper' program, say rkDumper_1.1.1.0, to gain a copy of the commercial Android firmware installation? There's also an unpopulated 3-pin header. Could this be my serial port?



Thanks for any advice, or direction.

Tressie.

Greetings, I'm looking for the right pins to Mask Rom Mode this board: it's a Tanix TX3 Mini with an Allwinner H616 processor and a e-Nand 617y. I've got an issue with USB Burning Tool not recognizing the device no matter how I plug it; with the reset button at the back it boots in the stock recovery mode, and Windows doesn't detect it; and with the reset button under the AV port it detects it but doesn't show up in the Burning Tool itself.

Other issues I had: Couldn't flash a ROM using an SD and Burn Card Maker; couldn't flash TWRP, couldn't unlock the boot ("fastboot flashing unlock" returns nothing)
