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: //github.com/96boards/documentation/blob/master/consumer/guides/qdl.md
The video: //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]
- something/lenovo-flash
- 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 deviceis 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.
- SP Flashtool [Download and unzip then run it]
- Stock firmware or Mirror - password: lenovo-forums.ru [Download and unzip]
- 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.
