[General Topics] Mhden2x:
I have experienced similar problems on Cyanogenmod just before it turns to Lineage on some other, older devices, that's why I always prefered AOSP based ROMs. On this device, fortunately I haven't noticed anyting suspicious yet (latest update and the tablet is rooted with magisk + xposed). I would recommend trying to clean cache, junk etc, which is a long shot but it may help. I use sd maid (I don't trust any other similar apps!) almost once or twice in a week. But it may not help at all, this device is kind of weird lol. If only the bootloader could be unlocked and a light AOSP ROM could be developed!

Given that we've got a locked bootloader, how on Earth does Magisk modify boot.img without breaking the boot chain security?

Is there a lesson to be learned here that could lead to flashing modified system images? We can modify recovery and boot. Why not system?

Hi! Firstly: thanks for the support. For me, the download failed two times, and then won't run the "volume up + power" thing... just the original service menu comes up, BUT after the third "failed" download, the TWRP runs flawlessly, and the following steps are also working, so I am satisfied now, and an owner of a succesfully ROOT-ed Lenovo P8 Plus :)

So, won't give up when failed the download, maybe just a bug, but it will be fine! ;)

I was wondering whether a custom rom can be flashed in twrp for those of us who have a rooted device with locked bootloader
[General Topics] daitalos:
hypothetically, with the last chinese version twrp 3.2.1-0 & RM Forceencrypt button, maybe yes....

_more easily ofcourse, for users with tb-8703x (bootloader can be unlocked normally via m/adb & fastboot > oem unlock-go etc..)

(only the Lenovo knows why there is this difference between two models...it is totally absurd!)
[General Topics] tweakradje:
[MENTION=5976373]daitalos[/MENTION] can't you flash only the part that is responsible for the unlocking from the X to the F version? Maybe only emmc_appsboot.mbn?

The unlock data could be in the /persist partition.

A few strings from emmc_appsboot.mbn (elf 32 bits executable)

oem unlock is not allowed
Need wipe userdata. Do 'fastboot oem unlock-go'
oem unlock
oem unlock-go
oem lock
oem device-info
oem enable-charger-screen
oem disable-charger-screen
oem off-mode-charge
oem select-display-panel

I also see these variables like: androidboot.mode=boot-factory (or normal)

I had a mediatek tablet once that accepted that. The partition was called "pre-loader" if I remember correctly. It was the only partition that allowed flashing with a locked bootloader.

Dunno how qualcomm does it.

I have this tablet on its way and would like it unlocked if it arrives. Good hardware. Although root access will be enough in the beginning.

EDIT: 4 may 2018 - digged a little further in to Qualcomm partitions. I have Redmi 4X and has same structure (aboot -> /dev/block/mmcblk0p19)

aboot is emmc_appsboot.mbn from flash file and is simple ELF ARM 32 executable.

Redmi 4X was locked too. But unlocked wit Mi tool after receiving code from Xiaomi. Same procedure as Motorola with the X version of the tablet.

I will try flash the Redmi 4X aboot into the P8. If it works you can get into edl mode (not supported by P8 aboot, see above fastboot list of oem commands)

From Redmi 4X aboot you see tehse oem commands:

oem unlock
oem lock
oem edl
oem device-info
oem enable-charger-screen
oem disable-charger-screen
oem off-mode-charge
oem select-display-panel

EDL mode is Qualcomm HS-USB QDLoader 9008

Te get EDL mode: Turn your device off. Then, press and hold the volume up button and connect your device to your PC via the USB cable (edit: maybe it must be Volume up + down + power!)

EDL mode supports flashing without encryption keys and certificates.

Already tried to run T4 P8 rom (Nougat) on it.

Boot.img worked fine without problem but couldn't use the system.img: was too Big.

T3 P8 has only 3GB system partition, T4 P8 has 4 GB system partition.

Then I stopped. Didn't have time to reduce system.img from T4 P8.

I combined kernel from T4 with ramdisk from T3 in my boot.img. It started al right after applying "RM ForceEncrypt" in TWRP.

Think there is no technical problem that prevent running custom ROM on our T3 P8.

Also source code for kernel is available and I read on 4PDA that someone already used it for TWRP. Maybe we only need TREBLE compatible boot partition.

Maybe soeone can ask proper person on 4PDA thread what the status is?

- Install SuperSu (if you want it)

- Apply RM Forceencrypt if it asks for password after reboot!

Failed to Open Comm Port Handle

Hi All,

Firstly thankyou so much for your hard work and for sharing all your work and thoughts.

For some reason, I get a failure when hitting "download" during the process in QFIL.

"error: function: port_connect: 100 Failed to open com port handle:" ( this happens about 15 times )

"error: function: main: 297 could not connect to \\.\com3"

Download fail; Sahara Fail: QSaharaServer Fail: Process Fail"

For the record:

1 - Have downloaded and installed drivers, QPST.

2 - ADB is installed.

3 - Have enabled USB debugging & OEM unlock

4 - Fastboot & ADB both recognise device properly via cmd prompt

5 - Windows recognises device

6 - QFIL recognises device as "Qualcomm HS-USB QDLoader 9008" ( com3 or com4 depending on usb slot I use)

7 - have tried different USB ports and dfferent USB cords...

It has to be something with QFIL specifically as the PC recognises the device fine in all other modes - suggesting that the USB cord / ports are working as normal.

Is there another setting in the tablet I need to turn on??

Any ideas at all would be very much appreciated.

Thanks in advance.

EDIT****

All ok - tried on a different PC and worked fine.

I really thank all those who are working on the Lineage OS 14.1 for this tablet, I followed all the guides and on my TAB3 8703X it works really well, at the moment I did not find any problems in using it.

Note: For the root I installed Magisk and everything works perfectly, the only thing to say is that after having done the root I had to reapply the RM Forceencrypt, because the tablet reminded me again the password at startup. After this everything worked perfectly.

Thank you!!!

Your set of instructions ends with: "14) Reboot into system and your device should now be rooted".

Does it mean this entire procedure brings you to rooting the device only?

Or does it flash the device with English stock ROM?

Flash TWRP via QFIL according to the thread procedure (successfully with latest TWRP 3.2.1)

Once in TWRP (i'm here) : i've not yet installed SU and not rebooted to system for now... ?

RM Forceencrypt (with DMVerity checked by default) and reboot to Recovery? to System before ? It's needed at least first time?

Flash "Magisk-v16.0.zip"

RM Forceencrypt (with DMVerity checked by default)

Wipe "Cache" and "Dalvik / ART Cache" (before reboot)

Reboot to System

Install MagiskManager-v5.7.0.apk

Enjoy

That's right?

Thanks!
[General Topics] Mhden2x:
Yep. Since you are already in TWRP, I don't think rebooting to TWRP is necessary, but just in case do it. At this stage RM Forceencrypt is NOT necessary either I guess.

Flash Magisk, now do RM Forceencrypt, wipe cache and Dalvik/ ART and then reboot to system. If it prompts you to install SuperSU, of course press "do not install".

Magisk works fine, on both Stock and LOS ROM.
[General Topics] verspax:
Works! Thank you so much ;)

How to install Magisk directly on your new TB-8703F?

Flash TWRP (latest version, you can) via QFIL according to the thread procedure (in first page) until step 11

Instead of install SU, flash "Magisk-v16.0.zip" (or latest version - don't Wipe Cache/Dalvik after this)

RM Forceencrypt (with DMVerity checked by default)

Wipe "Cache" and "Dalvik / ART Cache"

Reboot to System

Install MagiskManager-v5.7.0.apk (or latest version)

Enjoy

If system ask password for decrypt partition after reboot, go back in TWRP for reapply RM Forceencrypt (as step 3) and reboot.
