Member: 163 Status: Offline Thanks Meter: 7,841 | 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. b.r. Alex

Member: 163 Status: Offline Thanks Meter: 7,841 | 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. b.r. Alex

Member: 163 Status: Offline Thanks Meter: 7,841 | 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. b.r. Alex

Member: 163 Status: Offline Thanks Meter: 7,841 | 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. b.r. Alex

Member: 2906417 Status: Offline Thanks Meter: 0 | 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 |
