Okay,
BEFORE BEGIN - CHARGE FULLY your device/tab !!! FOLLOW ALL STEPS CAREFULLY ! (Especially part with formatting) !!!
All mistakes are made by you, and you only ! No one will warrant anything !
All goes on your responsibility!
Now, lets make this guide as much simple as possible.
- Download ROM, with all needed inside:
TB4-7304I_S000041_171018_ROW
- Unpack archive. pass: lenovo-forums.ru
- Start SPFT, from unpacked folder \TB-7304I_S000041_171018_ROW\i-x_flash_tool\
flash_tool.exe
- Select DA Agent -
DA_SWSEC.bin
- Load scatter file from root folder \TB-7304I_S000041_171018_ROW\
MT6737M_Android_scatter.txt
- Main SPFT Window, go to drop-down menu "Options" - "Option" - "Download" - select both fields, close window
- Main SPFT Window - Go to "Format" tab, select "Validation", "Manual format flash",
copy/paste marked in red "
Begin address" :
0x6a00000 , "
Format length" :
0x100000
- Press "Start" button, connect powered off device to cable.
- Wait for finish, green circle will be displayed (process goes fast - 4-7 seconds).
- Enter device recovery, make "Wipe data/Factory reset", then "Reboot device".
- FRP Should be gone.
If you encounter "DL Image Failed" or "Tool DL failed" in bottom left corner, and reboot,
Simply reflash device with provided rom.
(Same procedure, but you don't do any format, just from main window, Download button.)
p.s. Check attached images if something not clear. They explain all.
p.s.2 If you get some error like in
THIS post,
then also load authentication file in SPFT - "auth_sv5.auth"
Now, try and post results.
