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: TB-7304F_S000060_171019_ROW - MIRROR
- Unpack archive. pass: lenovo-forums.ru


- Start SPFT, from unpacked folder \TB-7304F_S000060_171019_ROW\Flash-tool_for_WLAN_no_sim_device\flash_tool.exe
- Select DA Agent - DA_PL.bin
- Load scatter file from root folder \TB-7304F_S000060_171019_ROW\MT8167_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" : 0x8000000 , "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.

Now, try and post results.

There is "authentication" file in same folder where SPFT is,
try to load it under third field (below scatter load field), name is "auth_sv5.auth" and retry operation.

If still the same, either you have different model, or you are doing something wrong.

This is for TB-7304F Model... Check your Model before this process.. Chipset MTK MT8167D


Download required tools and driver from here:

LENOVO TB-7304F FRP.zip

Extract zip "LENOVO TB-7304F FRP.zip"



Afterwards Extract Files in archive:



Install Drivers (Optional)


Open Flashtool:


Select "DA_PL.bin" (\Flash-tool\Flash-tool folder) in Download Agent

Select Scatter- loading file "MT8167_Android_scatter.txt" (\LENOVO TB-7304F FRP folder)






Afterwards Tick Format Tab at top... Select Manual Format Flash... Do not touch Region... Enter these:


Begin Adress[HEX]: 0x8000000
Format Length[HEX]: 0x100000






Click Start button... Power OFF device and connect with holding volume down...


Congratulations FRP is off... Reboot device and you will be able to bypass Wi-Fi (Google Account)

bro where am i getting wrong seems everything looks ok loading files ok DA ok what is the problem my cpu mt 8167A help me please to revive it

[Brka]

First and main problem is when you did FULL FORMAT of the device,
no idea where you got that (bad/stupid) idea.
With that move, you lost all calibrations, imei/wifi/bt/serial no.

Now, regarding this state of device ...

Try changing DA Agent into DA_SWSEC or DA_SWSEC_CRYPTO20 and try to flash preloader only.

Try all possible combinations of DA Agents, also try with or without holding volume buttons
when inserting usb cable into powered off device.

Some more info ...

TB-7304X - LTE , MT6737M
TB-7304i - 3G , MT8735D (which is basically same as MT6737M)
TB-7304F - Wi-Fi , MT8167

I read on other forums that someone with same problem,
solved it with using DA_SWSEC.bin and normal scatter + FIRMWARE UPGRADE option.

I suggest you to try the same.

I re-packed / re-uploaded SPFlashTools for TB-7304 series.

Download : SPFlashTool_Lenovo_TB-7304i-x-f

p.s. Try without auth file, with different model flasher, DA_PL, DA_SWSEC, something must work.
also, timing may be the problem - try holding power button and when device reboot, instantly press DOWNLOAD button, etc.

perfect instructions- working great.

Hi all, I have a TB-7304i- 3G , MT8735D, and would like to flash the ROM. The device does not have USB debugging under Developer Options.

Thanks to the SPFT posted by Brka, atlease now I can load scatter file. Prior to this, all SPFT I've downloaded will post C++ Runtime Error.

The scatter file posted in this thread is for MT8167, does it work with MT8735D? First time using SPFT and MTK chip.

Thanks
