Re: Lenovo TAB3 Business TB3-X70F TWRP down

Hallo Tzul

after 1h booting still stops at the lenovo logo ...  that actually happend before  when in the first attempt I used flashtool boot recovery. But at  that time I could go back to the original recovery   and that let me do a factory reset.

 

I had SR3-SuperSU-v2.79-SR3-20170114223742.zip installed.

 

To unbrick my phone I used  Lenovo_TB3-X70F_S000026_WC0E305514.zip via your recovery.

But no change.

Is it possible to flash the  Lenovo_TB3-X70F_S000026_WC0E305514.zip with an other flash tool?

I hope my german english doesn't confuse you...

Re: Lenovo TAB3 Business TB3-X70F TWRP down

The Lenovo_TB3-X70F_S000026_WC0E305514 firmware you used is for the Tab3 10 Business (TB3-X70F), but you have the Tab3 10 Plus! While it appears that these tablets are pretty much the same, except for the fact that the "Plus" model has only 16 GB internal storage, they use different firmwares.

If you made a backup of your tablet's original firmware when you first ran TWRP via "fastboot boot", then you should restore that. If you didn't make a backup, then you're out of luck, because I don't know a source for the Tab3 10 Plus firmware.

Re: Lenovo TAB3 Business TB3-X70F TWRP down

Had to sign up just to say thanks mate.
S000026 and latest SuperSU has worked brilliantly on my X70F and I'm having fun overclocking this to perform better with certain games! Much appreciated.

Re: Lenovo TAB3 Business TB3-X70F TWRP down

Hallo Tzul
Me again.

Thank you again for answering my questions!

I did a backup while on flashboot boot before flashing the recovery.
The backup contains system but no boot ,where as the backups I made after flashboot flash contain both. Could one separately flash the right boot image?


1.

When I restore the backup via twrp this shows:

Data successfully dercryted...
....
In red letters:
Unable to Mount storage
Failed to Mount '/data'. (invalid argument)
Then in normal colour:
Full SELinux support..

Then in red again:
Unable to Mount /data/mdedi/TWRP/.twrps

Then in normal:
MTP enabled...

After that it writes back data for some time and

finishes with done...

2

When I earlier did flashboot boot recovery ,before I flashed the recovery later, the tablet would stop at the logo ,when booted the device again.
I did factory reset ,at that time possible, and could start again from scratch.
Does that give hope, my device would start ,when I flash my backup on any other way?

Yes, you can flash the boot image separately.

Strange that the log says "data sucessfully decrypted" but then fails to mount /data.

You could try to format the data partition, using TWRP's "Wipe" menu. That will delete all user data from the internal storage, but it might fix the problem.

Re: Lenovo TAB3 Business TB3-X70F TWRP down

Hallo Tzul

Nothing worked to bring my tab back.I contacted the chat support with a bad  feeling. They generously take it for repair without nasty remarks!

You have been very helpful, but then there are such people one can not help.

Hopeful there will come a recovery for my tab. The code tb3 x70f for my lenovo tab 3 plus had misled me.

Anyway I have to thank you for the recovery you build for the lenovo tb3 710f ,which runs superb.

Hello Haema

I don't understand, when you say "I have to thank you for the recovery you build for the lenovo tb3 710f ,which runs superb.", you intall the tb3 710f  TWRP on TB3-X70F ?

 

How do you do to overclock the TB3-X70F ?

 

To unbring your tab back, have you tested "Smart Phone Flash Tool" with OTA 025 ROM in Tzul androidfilehost ?

Re: Lenovo TAB3 Business TB3-X70F TWRP down

Well, i have some problems with the TWRP on my tab3 10 plus (Edit: I don't understand the serial number is

TAB3 10 Business

Serial NumberHGER2X7C
Machine Type ModelZA0X0125SE

) . I've tried to unlocked it with

fastboot oem unlock

on the tablet screen

Unlock bootloader?

If you ... (some warnings on the unlock)

Press the Volume UP/Down buttons to select Yes or No.
Yes (Volume UP):Unlock(may void warranty).
No (Volume Down):Do not unlock bootloader.

So i press the Volume UP button

Unlock pass ... return to in 3s

on my PC screen (linux terminal adb/fastboot commands) :

fastboot oem unlock
...
(bootloader) Start unlock flow

OKAY [  4.981s]
finished. total time: 4.981s

then another tablet screen :

Select Boot Mode:
[VOLUME_UP to select. VOLUME_DOWN is OK.]

[Recovery mode]
[Fastboot Mode]  <<==
[Normal Boot]
=> FASTBOOT mode ...

I press the volume up button but nothing happen, nor if I press volume down button.

Then I flash the recovery :

fastboot flash recovery recovery_twrp303_TB3-X70F.img

and try to reboot system with

fastboot continue
resuming boot...
FAILED (remote: not support on security)
finished. total time: 0.002s
fastboot reboot
rebooting...

finished. total time: 3.009s

but nothing happen nor with :

fastboot reboot-bootloader

to reboot it I have a long press on power button. The tablet reboot on recovery but something is wrong : The Lenovo logo appears twice, but TWRP doesn't have a complete boot :

Data successfully decrypted, new block device:'/dev/block/dm-0'
Updating partition details...
...done
Successfully decrypted with default password.
Updating partition details...
...done

renamed stock recovery file in /system to prevent the
stock ROM from replacing TWRP.
(in red)

and it reboot in loop. I certainly do a mistake, but which one?
