2. Rockchip Batch Tool 1.8

If you have drivers installed for RKBatch tool then RKAndroid tool should also work as it is the same drivers. Bob There is no option to clear IDB in RKbatch, however RKBatch does recognize the MK808 in this mode as it gives a 'blue' square instead of the green (firmware update mode), flashing yellow (update in process), red (failure),. RockChip CM2RKT brick tablet. Batch Tool Unbrick. Chip Start Check Chip Success Get FlashInfo Start Get FlashInfo Success. The Windows tool for flashing the image is provided by Rockchip. To flash the update.img, you need to use the RKBatchTool and to flash the partitions, you will need to use RKDevelopTool. Both RKBatchTool and RKDevelopTool rely on the RK USB driver so you will need to install it first as below.

IMPORTANT: users can perform further manipulations at their own risk, and only if all other reflashing options can’t help.

This option can help if your device got soft or hard bricked. If you want try to reflash your device for the first time please check THIS article

BEFORE START

What you need:

Image file

Host PC

USB OTG Cable

Supported host OS: Windows XP (32/64bit) Windows 7 (32/64bit) Windows 8 (32/64bit) Windows 10 (32/64bit)

The first thing you need is to download the archive with firmware. Inside archive, you find:

BatchTool or Android Tool - tool for reflashing

DriverAssitant - tool to install drivers and firmware image file

Firmware image

All actions before reflashing are the same with the

INSTALLING DRIVERS

Launch RK DriverAssitant from the folder and press “Install Driver”.

Apply all changes and warnings during installation until finishing message

CONNECTING TO PC in MASKROM MODE

Maskrom mode is reflashing way, when you block reading data from NAND using hardware short circuit of NAND pins.

1. Open device housing and detect NAND (is standalone chip with 48 pins on two sides) on PCBA. In some boxes you also need detached heatsink or cooler in order to reach NAND

2. Place PCBA in front of you so you can clearly read NAND’s name and board number

3. You should choose 6th-7th or 7th-8th pin from NAND bottom on the right side or 6th-7th or 7th-8th pin from first pin (first pin is marked on PCBA with a point or ) and circuit it during plugging to Host PC and powering on (check pin sequence for other devices very clearly)

After circuit and attaching to host PC, Android tool will show you message in progress bar: Found one maskrom device.

Then start upgrade. The reflashing process should run several steps

You also can use Batch tool for this action. Device indication should turn blue instead of green for maskrom mode.

There are photos of several well spread NAND chips and circuit schemas:
