Rk Flash Tool

Boot Mode¶

eMMC flash is commonly soldered directly to the board. Some eMMC flash are pluggable, but it is hard to find a reader to use on PC. Therefore, eMMC is generally flashed onboard, that is, running to tiny system on the obard, which reads firmware data from PC and flashes to eMMC.

Depending on the existing data on the eMMC flash, there are two special boot modes: Rockusb Mode and Maskrom Mode.

You usually just need to enter Rockusb Mode for upgrading an existing Android OS or Firefly Ubuntu OS, which is packed with RK Firmware format.

  • RockChip RK Batch Tool (ROM Flash Tool) v.2.1 - is an utility for flashing Android tablets, e-books and MID devices based on Fuzhou Rockchips (RK2818, RK2808A, RK2918, RK3066, RK3188, RK3288 and etc.) SoC and manufactured by Tronsmart, Wexler, Pipo, Minix, Explay, Ritmix, ONDA, Teclast, Texet, etc.

Maskrom Mode is the last resort when Rockusb Mode is not available due to bootloader damage, or you need to flash Raw Firmware to eMMC.

Rockusb Mode¶

After the flashing, a success message will appear. Disconnect your phone and turn on. More Tools:-Download Latest Sony Mobile Flasher v0.9.28.0 (Xperia Flashing tool) Download Moto RSD Lite Flash Tool For Windows V6.2.4; Download All Versions LG Flash Tool To Flash Firmware on LG devices.

If the board powers on and finds a valid IDB (IDentity Block) in the eMMC, it will continue to load the bootloader from the eMMC and pass execution control to it. If the bootloader checks that the Recovery button is pressed and USB connection is made, then it enters the so-called Rockusb Mode, waiting for further instructions from the host.

Requirement:

  • 5V2A power adapter.

  • Micro USB cable to connect power adapter and board.

  • Male to male USB cable to connect host PC and board.

  • eMMC.

Steps:

  1. Pull all the USB cables (including micro USB cable and male to male USB cable) out of the board, to keep the board powering off.

  2. Install the eMMC and pull out the SD card.

  3. Use the male to male USB cable to connect the host PC with the USB 2.0 OTG port (the lower one in the double-decker ports) of the board.

  4. Keep the RECOVERY button on the board pressed.

  5. Plug in the micro USB cable to the board to power up.

  6. Wait about 3 seconds before releasing the RECOVERY button.

Maskrom Mode¶

If anyone of the following conditions is met when the board powers on:

  • eMMC is empty.

  • The bootloader on eMMC is damaged.

  • eMMC read data failed by connecting eMMC data/clock pin to ground.

then no valid IDB (IDentity Block) will be found in the eMMC. The CPU will execute a small ROM code, waiting for the host to upload via USB a small DDR blob to initialize the DDR memory, and later a full bootloader to handle further firmware upgrading. This mode is called Maskrom Mode.

It involves hardware operation to force into MaskRom Mode, which has certain risk and should be carried out VERY CAREFULLY.

Requirement:

  • 5V2A power adapter.

  • Micro USB cable to connect power adapter and board.

  • Male to male USB cable to connect host PC and board.

  • Metal tweezers to connect eMMC clock pin to ground.

  • eMMC.

Steps:

  1. Pull all the USB cables (including micro USB cable and male to male USB cable) out of the board, to keep the board power off.

  2. Install the eMMC and pull out the SD card.

  3. Use a male to male USB cable to connect your host PC and USB OTG port of the board:

  4. Find the reserved eMMC CLK and GND pads on the board, as shown below:

  5. Connect the eMMC CLK and GND pads with metal tweezers and keep holding steadily.

  6. Plug in the micro USB cable to the board to power on.

  7. Wait about 1 seconds before releasing the metal tweezers.

Download Firmware¶

Firmware description: the firmware is classified into Raw Firmware and RK Firmware, which are placed into different folders. The latest firmware is the one with the latest date, which is often more stable. Please choose the correct tool to flash according to the type of firmware you need.

Linux (GPT) firmware: The Linux firmware files, including Ubuntu, Buildroot, Debian and other Linux systems, contain GPT in the filenames which means that they are using GPT partition scheme. They are referred to as Linux(GPT)firmware, which can be compiled in the Compile Linux firmware(GPT) chapter.

Flashing Instructions¶

The flashing tools and flashing methods used between different firmware are different. Please follow the table below to flash.

Upgrade Guide can help you to reflash your device based on different RK SoCs

This is a common guide for reflashing RockChip based devices. All RK SoC (RK3066, RK3188, RK3288, RK3229, RK3328, RK3399 and so on) supports the same applications and drivers for Host system, if 3rd party producers do not add any other limitations or special options. Differences can be in hardware parts, so you need to detect OTG port and recovery buttons correctly.
Notice: this guide is 100% working with Ugoos RK devices.


BEFORE START

What do you need:

Rkflashtool

- 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 (separate Android Tool and drivers you can download HERE)
- DriverAssitant - tool to install drivers and firmware image file
- Firmware image


INSTALLING DRIVERS

Launch RK DriverAssitant and press “Install Driver”

Apply all changes and warnings during installation until finishing message

CONNECTING TO PC

Run Batch tool or Android tool on your host PC.

In order to connect device with Host PC and run bootloader mode you should perform following steps:

1. Plug off device power adaptor.

2. Connect device to computer via usb OTG port, much better to use certified OTG USB cable from package.

3. Run Batch tool or RK Android tool

4. Hold the hardware recovery button.

5. Plug in power adaptor and Turn on device if not turning on automatically.

Tip: if you can’t hold recovery button or it’s broken you can reboot to bootloader from Ugoos power menu.
