Yes is true.I do not know what Lenovo is doing,I don't think he not knows the problem
device perhaps has a problem with bootloader or & recovery also (or maybe with partitions sizes) ..let us hope,Lenovo to fix it,the device has good features & in good price .he policy followed by Lenovo is unacceptable (do not allow unlocking of the bootloader ! )

bravo, good job, man. thanks so much for this post!
i've done this flash thing already. and be careful that your wifi&bluetooth mac address gonna changed.
and also, it's better to backup Qcn file first.

---------- Post added at 10:09 PM ---------- Previous post was at 10:03 PM ----------

oh, there is question, i wanna make a full backup of the stock rom entirely, there is a post about it, https://forum.xda-developers.com/gen...-root-t3570178,
im not pretty sure about the process, have you done it or know how to do it?

not download to the tab, but read from the tab, can qfil do this job?

not download to the tab, but read from the tab, can qfil do this job?[/QUOTE]

Full backup via qfil No! I do not know what he wants to do, but stay away, it is very dangerous all this for hard brick !
For full backup needed or custom recovery (nandroid backup) or rooted device & use some tool from playstore for backup etc..
You can flash twrp : https://forum.xda-developers.com/gen...2#post74281359
and after you can get a full nandroid backup ..
except all this, backup for stock rom? and how to restore the backup? also, even if you have the twrp probably will not be able to restore a factory image backup...

I just want to know how is this file dumped or where did the Russians got this file.

Before I downloaded this file into my tablet, I flashed trwp recovery, and made a full backup of the Chinese version ROM . BUT the ORIGINAL lenovo recovery WAS GONE , RIGHT?
SO ..... without the original recovery the backup cannot be called a full backup right

I told you...custom recovery can not flash (or reset) factory image backup (this version twrp decrypt device because Lenovo P8 has a locked bootloader etc..)
backup of stock rom is useless in this device, you can flash stock rom if you want, via Qfil
