Hi, I tried compiling U-Boot for RK3399. I have the files and flashed it via AndroidTool v2.38. But when I flashed uboot.img it say cannot find uboot offset. And when I flashed the trust.img file I get this:

And it bootloops.

I tried booting into maskrom mode to flash it again. After booting into maskrom and flashing it again, it now no longer boot, even from maskrom mode. No output from UART. AndroidTool does not show any devices.

How do I restore it back now? Thanks!

Sometimes randomly the device will come back and Android Tool will say “Found One LOADER Device”. But when I try to flash anything I get “Prepare IDB Fail”. How can I fix this?

OK now it’s in MASKROM mode I think. What image should I flash to get it back to order? I can’t find the download. Thanks!
