Not entirely sure , what sign in problem you mean but I think you are referring to the Google Account Verification after factory reset on Lenovo TAB-3 7 Essential . To fix this issue you will need to do a "Hard Reset"
are you Pressing and holding the Volume Up + Power button simultaneously for about 10 seconds ? it should appear as shown in above screenshot ..share your Bootloader image so i can guide you about Flashing
Same window comes Vol up + power & Vol up+Vol Down+Power..
Now how to flash or any other solution Khan sab......
Select the option "reboot to bootloader" and also show me its image.
Image sizes shouldn't be more thn 1 MB :p anyway you can always use https://img.drhack.net for heavy images and all
let me know the bootloader image so we start with flashing your Lenovo Tab 3 7 Essential
You will need a Computer , USB Cable & your tablet for this process, if you have these things keep on reading.
maybe I missed some thing while installing. rest did everything as per your instruction. selected: BootImg , Android , UserData
you shouldn't miss anything .kindly follow it exactly and if you face any errors let me know so we resolve them
I am failure in this task. I did as per the instruction but. Going to give it back to kid.
Complicated to flash.
what is this message. tried right now and this window came.
I tried to upload this window from mobile but i couldn't. not mobile supported and please let it more than 1mb to upload to. everytime have to resize than upload :)
Oh good , you tried again .. this message means your Tablet has a different model version , I will get you appropriate firmware for your Lenovo Tab3 7 Essentials MT6580 . Its weekend so can not tell how quick i will be :P .. and as per Image, as I earlier told you may upload all your images on img.drhack.net :) .and i will increase image size to 2MB
Firmware for : S00029 (This should work for you model ) and the download is real
and for update to S00030 with Recovery
"for update to S00030 with Recovery" what to do with this update? have downloaded but not clear what to with it?
now this is weird , give this link a glance .. it is same but maybe a difference in explaining might help you a bit ?
give this ROM a Try : S00030 with Recovery , and after flashing open its recovery tell me if TWRP has been flashed or not ..
give this ROM a Try : S00030 with Recovery , ... how to give it a try. please not clear how to proceed with it.
you proceed using the procedure as mentioned in this comment , but in Step 3 : use the Firmware S00030 with Recovery .
But be aware of one thing , if you click the download button in SPFT after connecting the tablet, or after rebooting? If you do this IT WILL NOT WORK.
Click the download button first, then connect the tablet which should be OFF. That's due to the way MediaTek has implemented this..
No matter device get back on or not. You still deserve a treat. You are welcome for a treat anytime.
Let's make the deal final??
And here the new message!
Hope you doing it while the TAB is off ?
also after you flash the firmware 29 , Download this Custom TWRP Recovery for your Tab and only select the "Recovery" partition and flash it ..using the same procedure as mentioned above. once down open "Recovery on your Tab" as already mentioned in above comments..if custom recovery opens up their you need to format the partition "frp" that is the "Factory Reset Protection" partition which is storing the Google Account information to prevent misuse .
My treat is getting this damn tab to work :p
That is an issue with Android File Host , I have asked them for resolve the "OOPS! - no mirrors found." issue . Its a wait game for now
Issue is resolved , you may begin your download from the link given above as download servers error is fixed
Hurrah! Done. Its working now. What process worked don't know. Kept trying and finally succeeded.
Your treat is confirmed once again.
