Useless guide for me.

Hi , what I ve done wrong ??! . THX.
It's not your fault...Is a known "sahara error" ...
read here how to fix it : https://xdaforums.com/android/development/lenovo-p8-tb-8703f-wifi-how-to-flash-t3720621
or use google search for "sahara error" in Qfil etc...

I know it might be too late to reply or maybe you already fixed you problem.
Same error here. Followed the sahara fix passes but I changed something from what I see you did.
I put the root files to load in Qfil in a shorter named folder directly in c:\ and used one of my few usb 2.0 port on my pc.
And...this time it worked!

This has been some time, but sahara problem is now solved here. I just cannot believe it. The device wasn't even in USB debugging mode back then, as I had never even enabled developer options. Embarrassing. Tried it again and now everything worked like a charm, the tablet is up again and running LineageOS with gapps and Magisk...

Root not work
after doing root, root does not work as it should, you can give permissions to the TB app or other demanding root permissions but you can't e.g. copy files to the system, with r / w suddenly it gets r / 0 every time. likewise, xposed cannot be installed. pic in link

Hi friends,
My 8703-f is not being recognized at QFIL. May be because my windows version is 64bits?
I did everything and don't work....
Someone can help me?

33I found this version of TWRP on the official Chinese Lenovo forum (original thread). The Lenovo P8 was originally released in the Chinese market, but there is now a version with an English stock ROM and full Play Store access being sold online.
The instructions I have written also work for the 4G model (TB-8703X) but you will be using a different version of TWRP (see below).
Notes:
This method installs TWRP and SuperSU without unlocking the bootloader. As such, there are some risks involved. Pay special attention to the steps labeled ''IMPORTANT'' to prevent a bootloop from occurring.
Necessary files:
QPST flash tool (use the latest version): https://androidmtk.com/download-qpst-flash-tool
Qualcomm USB driver : https://androiddatahost.com/nbyn6
TWRP:
- If you have the WiFi TB-8703F model, use TWRP-3.1.1-0821-LENOVO_P8(8703F)-CN-wzsx150-QPST.7z: http://www.mediafire.com/file/s6wpp3eic9gvp2y/TWRP-3.1.1-0821-LENOVO_P8(8703F)-CN-wzsx150-QPST.7z
- If you have the 4G TB-8703X model, use TWRP-3.1.1-0820-LENOVO_P8(8703X)-CN-wzsx150-QPST.7z: http://www.mediafire.com/file/o3qoa4hws0t7g16/TWRP-3.1.1-0820-LENOVO_P8(8703X)-CN-wzsx150-QPST.7z
Instructions:
1) Install QPST and the Qualcomm USB driver from the above links. Also extract the TWRP archive specific to your model number
2) Run QFIL (part of the QPST package), and select the build type ''Flat Build''
3) Next to ''Select Programmer'' click ''browse'' and select prog_emmc_firehose_8953_ddr.mbn (located in your TWRP folder)
4) Next to ''Select Build'' click ''Load XML'' and select rawprogram0.xml and then select patch0.xml (both located in your TWRP folder)
5) Turn your device off. Then, press and hold the volume up button and connect your device to your PC via the USB cable
6) QFIL should detect your device in 9008 mode (''Qualcomm HS-USB QDLoader 9008'' will appear at the top)
7) Click the blue ''Download'' button
8) IMPORTANT - once it has finished downloading, disconnect the device and enter TWRP by holding the volume up and power button together (it should vibrate just before loading into TWRP)
9) You will notice that TWRP is in Chinese, but we will now change the language to English. Slide the slider at the bottom all the way to the right, and click the grey button that is second to last in the right column (see here). Then, click the white globle icon at the top right (see here), and set the language to English (see here)
10) IMPORTANT - Press ''Advanced'' and then ''RM Forceencrypt''. Swipe to confirm. Now reboot into system (do not install SuperSU just yet).
11) Once it successfully boots into Android, power down the device again and enter TWRP (hold volume up + power button together)
12) Press ''Advanced'' and then ''Install SU'. Swipe to install.
13) IMPORTANT - after SU successfully installs, go back to the main menu, click ''Advanced'' and then ''RM Forceencrypt''. Swipe to confirm.
14) Reboot into system and your device should now be rooted
Findings:
I encountered a small issue with AdAway not loading initially. This was easily fixed by going into the SuperSU app and changing the setting ''Default access'' to ''grant''. After you successfully load AdAway and see the ''grant permissions'' popup, you can revert the setting back to ''Prompt'' in SuperSU.

Special thanks to @wzsx150 and the L.R Team for creating this version of TWRP.9Lenovo P8 - After Rooting - improvements
After Rooting device we can few things (no custom roms there,no developing)...
for example, we can open MultiWindow, themes,emoji changer(android O) & some build.prop tweaks (for the better operation of the device)
_How to Enable Multi-Window : open buildprop line & change the value of build type from user to userdebug & Reboot device... (In developer options will see a new choise : Multi-window mode) ≥ see the second screenshot..
__Enable multiwindow mode with two ways: using an app from playstore very easy,(build.prop editor,Root Essentials etc) or using adb & pc : https://xdaforums.com/android/general/guide-enable-multi-window-mode-android-t3121483

__ from Root Essentials buildprop, the backup is mandatory....From other app, (buildprop editor etc) we get backup the current buildprop settings before all this!! because all these have a risks! (maybe bootloop)

Follow this step by step!!!
- go into TWRP
- backup DATA, SYSTEM and BOOT
- Advance wipe DATA and CACHE (Not Format Data)
- install lineage.zip
-install adreno patch if you have wifi version!
- Install SuperSu (if you want it)
- Apply RM Forceencrypt if it asks for password after reboot!
- reboot
Big thanks to HighwayStar from 4pda.
ps: he will create new thread for this ROM on XDA soon. Don't post in this thread please.
Respect the OP. Thanks.
