Hướng dẫn flash stock rom lenovo k800 năm 2024

This thread is meant to help regarding issues with flashing a lenovo stock rom with device in EDL-mode using the QDL-tool for Linux.

I've made a short video, of how I flash the stock rom. Mabe it helps to understand the written steps. I am using a self compiled version, since it was the most reliable way to get the tool running without issues.

Help for compiling and other helpful information regarding QDL is given here: https://github.com/96boards/documentation/blob/master/consumer/guides/qdl.md

The video: https://drive.google.com/file/d/13YKJp5dUKnpD7KKy4_IfuAJCIVFq7_UT/view?usp=sharing

The steps I made in the video in words:

• My file-tree-structure looks like this:
  • something/lenovo-flash
    • qdl (qdl tool folder)
    • x605
      • TB-X605L_S210224_200910_ROW (stock rom folder)
• I am in the stock rom folder and have to call qdl tool from two parentfolders above, thats why I do: ../../qdl/qdl
• I have connected an USB-A to USB-C cable to the computer but NOT YET to the device
• I enter following command in the terminal: ../../qdl/qdl prog_emmc_firehose_8953_ddr.mbn rawprogram_unsparse_upgrade.xml patch0.xml
• The message Waiting for EDL device is displayed
• I press both volume buttons of the device with my thumb at keep them pressed while I connect the USB-C end of the cable to my device
• The device turns on and shows the Lenovo logo, I still keep the volume buttons pressed
• The device display turns black
• In the terminal, the qdl tool starts to do something -> I release the volume keys
• Now I just need to wait until the tool finished

If you get error messages from the qdl tool, it may be caused by the version of qdl you are using (snap or a specific distro package), thats why I strongly recommend to use a self compiled version.

Reading from your previous question, the model is `Lenovo tab 2 A7-10`which has a Mediatek chipset (Mediatek MT8127). So you need SP Flashtool and the firmware with a scatter file to be able to flash your device.

1. SP Flashtool (Download and unzip then run it)
2. Stock firmware or Mirror - password: lenovo-forums.ru (Download and unzip)
3. MTK VCOM, CDC Drivers or Mirror (Download and install)

Install the drivers for the computer to be able to detect the device. Power down your device. If you can't, just force shut it down (Keep pressing Power button + volume down button for a couple of seconds).

On SP Flashtool, click on Scatter-Loading: Browse to the folder where you unzipped the firmware, you'll find a text file similar to this: MTXXXX_Android_scatter.txt. select it.

You'll be back in the SP Flashtool interface, uncheck the first field (Preloader) and leave the other checked.

Click on Download (green arrow) and wait the software do its things. You should get a big green checkmark if everything goes fine.
