RK3229 R-Box Plus Brick, No Boot or Power after TWRP install attempt

[Droid_Help]

The box originally was stuck at the logo screen. I flashed the firmware via pc with Factory Tool. (Worked)
I wanted a custom recovery so i tried to install TWRP, the first time i used the Android Tool I only selected "Recovery" (everything said it was good, downloaded and checked the firmware)
but whenever i rebooted into recovery mode it was still stock recovery. After a couple more failed attempts i decided to select all that it would let me which is pictured.

After It got done the last time, I unplugged it, connected it to the tv to check it and there was no power. NO RED BUTTON/ NO BLUE BUTTON & I tried to hard reset it so i can flash it and I got nothing. My computer no longer recognizes that it's being connected - whenever i hold the reset button in the AV Port with it being connected to my pc it doesn't make sound. If i connected the power charger (I've tried 3 charges just to make sure) I get no power.

Does anyone have any suggestions, I've never installed TWRP but usually im pretty good at figuring things out until now

Hi ,

you must use the "shortPins" Way , so called "MaskRomMode" for RKBoxes to restore , look here :

Thanks for the info. I did try to short the pins however it didn't work. I'm gonna keep trying to find out more info about shorting the pins
maybe there's another connection point somewhere else i can do it.

Hi ,

try Pin 7/8 on NandChip , if available ,
you not uploaded Pictures of both sides of full PCB , so i cant see if Nand has solder rows , did you connect Power too ???

connect USB before / correct Port
short Pins 7/8 / hold it
connect Power

PC makes Sound / Tool shows "Maskrommode" / leave the Pins when you hear or see it ,

now you can "restore" your Box ,


good luck / gefattern

I did not connect the power adapter, only the male to male cord to my pc.
I also tried to short pins 7/8. I will try again right now with the power cord and let you know how it goes.
**UPDATE**

So i tried it with the power adapter and it made no difference. Maybe my box is done. It literally has no red or blue lights whenever the power is connected

Hi ,

if you only flashed the .img Files that are shown in Picture above it is for sure bricked , you not flashed the / loader / misc / recource / boot / system , so it must brick , but i not understand why you cant get it to "Maskrommode" , and why you not posted Pictures of both sides of PCB , you can look on YT for Video guides how to get to MRM ,

The wifi chip is pictured here from the first post. It is a RTL 8723bs https://forum.freaktab.com/forum/tv-...nstall-attempt

Here is the firmware that originally was on it
