Main and upto date thread here
Kinhank G1

This is a quick run down on how we got here and what is needed to get the most of KinHank G1,

Thanks to Sholander , tasmansaroha and everyone else who contributed

and special thanks to hungphutho and ofcourse Team CoreELEC for which none of this would exist without.

So for what happened , KinHank made a fireware update that locked out bootloader and no OS like CoreELEC could be installed or accessed, a developer hungphutho

i made custom android tv fw version for G1 based on latest ota (Link to public dowload Firmware img 781.46 MB file on MEGA) , has features like .

  1. Unlock developer options
  2. default will Boot coreelec in SDcard and USB
  3. DV / HDR adaptive
  4. block update ota
  5. Remove bloatware
  6. work all google services , netfix …
    (7. this new version SPDIF audio port works after the uart cable mod below)

To flash this firmware, you must not update ota.

This is the instructions provided by @Sholander

Here are two tutorial versions, SD with sound, and HD without sound, link

Short instruction:
Install “V3_setup_V3.2.8.exe” on a Win PC
Load “dv8910-hungphutho-v1.img” to Burning Tool
UNCHECK “Verify Bootloader” BOX !!!
Connect G1 with USB_A to USB_A cable to PC (use 2nd USB port away from uSD card port)
Press and hold Reset button and apply power to G1.
(Flashing should start now. If it does not, disconnect box and close Burn Tool. Repeat
the procedure until it starts flashing. I had to do it twice before it started flashing)
After it flashes for about 5-10 seconds release Reset button.
When flashing finishes close Burn Tool.
RUN “flash.bat” file…

Edit: Link to public dowload Firmware img 781.46 MB file on MEGA
Link to download video instructions (provided by hungphutho) from here

NO! To be on the safe side DO NOT OPEN ANDROID before you flash this firmware!
If you want to check if the box is with original, not blocked, firmware just install CoreElec -ng version. If you get CE working, your box is ready for this firmware.
If you cannot install CE on your new box, either return it, or use only Android on it…

That’s all, enjoy Smile

can you show a picture of where you connected the UART to the G1? Did you have to solder? [edit – I do see the GND, Rx, Tx, Gnd to the left of your photo - that is fine]

this is the UART cable that hungphutho used
https://www.amazon.com/WWZMDiB-CP2102-USB-TTL-Programming/dp/B0BCYRFZJD/

can be sourced from Aliexpress for much cheaper

get the CP2102 Red, second option for $1.56 (pre tax)

From thegryghost, he got it to work without the need to solder

I was able to do it without soldering and had to try a few times since I had emmc timeout errors but eventually got it working.

This has Netflix is ​​4K tested by hungphutho

This is recommended by kenicsabi

and I recommend to buy the uart cable alongside your order since it’s so cheap ($1.56) just in case the hardware is updated (Cp2102/ch9102 usb 2,0 to uart ttl 6/5pin stecker modul serieller konverter stc ersetzen ft232 ch340 pl2303 cp2102 micro usb - AliExpress 502)

make sure it’s the second one CP2102 Red

please note their is boxes that have the 1 gigabit ethernet and others that are restricted to 100Mb, I’m guessing the first few batches have the gigabit and future releases will have a 100Mb ethernet

Hope that’s everything to help get your G1 running.
