NAND Chip Mask ROM Mode Short Location

[dogukanbild]

Hi friends i bought hk1 mini plus rk 3318 about one month ago when updating electricity gone then it stuck on red light not opening searched on this forum and i figure out it was bricked i tried on batchmode and android tool , factory tool it showing blue mode (maskmode ready) every program i tried showing error idb failed i will try short circuit method please anybody can show me pin points.

both not that easy due to BGA board chips

I tried lot of pins but without luck...

[soldiaz]

Keep in mind to insert USB plug WHILE (!) shortening!!

[Nebojsa]

Yes I tried that way, connect power, press and hold reset button, short pins and insert USB plug, but nothing.

Yes I tried that way, connect power, (_{press andhold reset button}), short pins and insert USB plug, but nothing.

1. Connect PC ( while running UBTool ) and tv box with USB male-male cable.
2. Connect power adapter to the box.
3. Short pins and you should have connection...

Tried lot's of variants but without luck.

connect to pc, connect power, shorting pins
connect power, shorting pins, connect to pc
shorting pins, connect to pc without power
press recovery, connect to pc
press recovery, connect power, connect to pc
press recovery, connect power, shorting pins, connect to pc

Maybe I'm using wrong pins.
PC, cable and drivers are ok, tried to connect other working box and it's recognized without problems.

Also tried to boot with SD card.
Made bootable SD card with Rockchip Create Upgrade Disk Tool v1.53 but won't boot, nothing works.

You're already in MASKROM mode. What did you do to get to this point?

sorry to answer too late,I went and flash the box with android 7 with loader Rk devtool 2.42 but the box was allredy with android 7!!! so now it won't load nothing i keep getting IDB FAIL everytime and if you see my nand is diferent spectek PFG57 FBNL05B128G1KDBABJ4 NAND FLASH

I'm looking for this chip's pin short (Nexbox A95X (S905) ) . Thx!

I found three shorts on the NAND, 1-2; 12-13; 35-36, but none of these helped to upload rom. USB Burning Tool's stops : 1% Download DDR

I've attached a USB-TTL device , and connected with Putty over serial. The output:

Does someone here know which pins to short for the Vontar X96 max 4GB/32gb?

Thanks

Must be in the other side of your motherboard.
Take a better picture (better resolution)

HM8 ,mecool

hhhh

[mody_bodey]

another picture for HM8, hope it\s more clear, Its red lamp, only by using sd it is working but never accept any firmware. and the green lamp appear
any idea how shorting NAND can solve the issue? and which pins
