Looking for some kind of a assistance, I'm out of ideas.
Introducing the culprit: GOCLEVER nanoDROID X2 (link to brand, front, back)
Specifications: Android 4.1.1, RK3066, Mali 400, DDR3 1GB, 4GB Nand
Connectivity: 1xHDMI/USB2.0/MicroSD/MicroUSB-power WiFI:RTL8189ES
Buttons: 1xButton (to PowerON hold ~4sec, to PowerOFF ~9sec).


What I needed: Android TV stick with working screen rotation functionality.
What I got: Android TV stick with locked rotation (no market app could override that), that I successfully rooted, got a working CWM recovery, did a full backup. So far so good.
What I did wrong: Edited buildprop (...sf rotate something - changed from 0 to 180) and on the next boot the screen stuck upside down (the android loading screen, bootloader was fine). Then I discovered that I cannot enter recovery because there are no hardware buttons to do so. ADB did not work. Then I did a comprehensive research - xda developers, this site and many others. I found out about the 8 and 9 pins. And it worked! I got it into the mask mode. Searched for the stock FW (rk30sdk-eng 4.1.1 20130129_v1.0.3) and found none. Later found something similar. Tried RESTORE with Batch tool - got an error (image 1). Tried UPGRADE - error (image 2). Tried to ERASE nand with RKAndroid Tool - using the bundle mk808_finless_17c ROM - error (image 3). Tried flashing - error (image 4). At this point I plugged it into the TV, no changes - loader OK, boot screen upside down and after that it freezes. OK. Moving on - tried to rewrite something - something happened (image 5), tried other parts of the package - did all of them except the loader (it was not working at all...) - the same - download file failed. When I finally got to the smallest of them - i got something working - download OK and the device disconnects from the PC after that (image 6). At this point I connected the device to the TV, and got a dredded boot loop - bootloader loads and after that device shuts down. Tried different versions of these tools - the same.
Tried to connect using different cables (different length, brand), different computers: windows 7 x64 sp1 with Intel i7-3***, windows 7 x64 sp1 on an old dual core AMD machine, windows xp sp3 on a HPCompaq desktop with celeron 1.7 inside. Tried back and front USB connectors, nothing. Power is not an issue - it was working originally from the Intel i7 desktop pc plugged in the front and connected to the LCD screen.
Extensively searching I found user who posted about his success with Finless 1.7 rom with this exact device, I have sent him a message, but as of now he has not answered me.
Found posts about different pins - Tried the 5-6 pin trick from the other side - device shows up but shuts down after few seconds - and as a results the connection with the pc is severed. Tried 30/31 pin and pin 9/10 - the same, connects and then shuts down after few seconds.
TLDR: Can not erase NAND. Pins 8/9 trick is working OK. Gallery with all the images here. Here is the CWM full backup link1, mirror link2.
Is there anything that I could try to do that I have not yet tried? Or should I give up on this damn fake device and order the original Chinese version?
