Thank you, trebor, for the firmware links.
Has anyone managed to login to Android or to break into either the Rockchip or the U-Boot boot loader using the serial console?
I have only managed to get the boot loaders' log output but unfortunately I get no further output once the Android/Linux kernel starts booting.
I thought the baud rate might have changed but setserial says it is 1.5 Mbps as for the boot loaders.
The situation is the same with both the stock firmware and trebor's firmware.
I have also been unable to get Bluetooth working: it disables itself almost immediately.
Judging from dmesg there seems to be a conflict between BT and the serial console.
UPDATE: BT works if I unsolder my serial console. So there is clearly an interaction between them
I should be most grateful for any help.Last edited by segv; 09-14-2017, 18:49.

I found a solution to three problems.
1 - only brum sound on AV output (stereo output),
2 - freezing the box on alternative firmware,
3 - low quality wifi or bluetooth signal.
Check the dimensions of the jack plug and select the appropriate drill bit.
Open the casing and remove the motherboard - check that it works on this cable.
Enlarge the AV output hole.
Make sure your wifi and bluetooth antennas are not short circuited. Solder again if there is a short circuit.
My device overheated. The heatsink is very small and was badly glued.
Gently remove the heat sink from the processor. Remove the adhesive tape. For gluing, use a thermal adhesive, do not use adhesive tape. The processor is not flat and the tape is not covere on the processor. If you have - use a thicker heat sink.

Hello,
Can anyone provide firmware image for Z28Pro PCB XJH-RK28-V11.
Stock Build: rk3328_box-userdebug 7.1.2 NHG47K eng.qinzhendong.20170830.225537 test-keys
Flashed superceleron SCV2 , and now it does not pass boot.
I think it have something to do with loader.
Already tried:
Restore, via AndroidTool 2.3.9, with partition images, backup made with rkDumper 1.05
Flashed Z28_universal_stock_supersu_10_08_2017
Flashed LUSHEN_XJH_RK28_V10_A7_1_RTL8822BS_Z28Pro_20170727 115958
Rectification:
managed to install superceleron SCV2 in XJH-RK28-V11
unpacked firmware.img and installed all partitions except the loader
correct loader is MillionALL.bin

I have aquestion.
Who have Alfawise z28pro using with 4K TV?
Is The resolution really 4k? (mine is 1080p)
In Kodi looking about device i see resolution 1280x720, is that mean my videos are only 720p?
