Root [YB1--X90L] how to

danjac · Jan 8, 2017

well, now it's getting interesting.

supersu didn't work for me (always failed to patch boot.img) but i found another way to get root. xda is just great.

it's definitely not my work...just used other people's achievements, so all credits go to them!!!

!!! Please, don't blame me if sth goes wrong. It worked for me and my model. Do it on your won risk!

!!! Before you do anything, back up your phone (in TWRP)

so what you need to gain root:
Yoga Book [YB1-X9OL]
working ADB --> e.g. see here
unlocked bootloader --> see here (unlocking the bootloader does a factory reset, so back up your data)
twrp_recovery --> see here (do not flash it, just boot temporarily)
files for root --> see end of post

1. download attached file
2. boot twrp
3. install 1-Magisk-v7.zip
4. install 2-phh-superuser-magisk-r259.zip
5. reboot
6. install 3-Phh Superuser_1.0.3.3.apk
7. install a root checker to verify

got this way from here: https://xdaforums.com/honor-4x/help/honor-4x-che1-l04-mm-6-0-1-emui-4-root-t3475854/
more about magisk can be found here (maybe even a newer solution/version): https://xdaforums.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445

screenshot:

files for root: View attachment MMroot.zip

EDIT:
You can also use the newest version of Magisk (v.10.2.) to get root, but then follow the following steps:
1. download and install the newest magisk.zip via twrp, phh's superuser is already included, so no need to install it seperately (as with v.7)
2. reboot system
3. install phh's superuser manager from playstore

!!!if you want to update from Magisk v.7., don't do it with magiskmanager cause it will break root.
donwload Magisk's uninstaller.zip (get it here) and install it via twrp before you install v.10.2.

Hey

What method do you recommend for backing up everything before unlocking for those who do not use google or lenovo services?

heldc · Jan 10, 2017

So why do you say to not actually flash TWRP, but to only boot to it temporarily? Does this fail if you properly flash TWRP?

west0ne · Jan 10, 2017

Anyone tried this on the non-LTE version YB1-X90F?

i think it would work. i think most important is to know whether partitions are the same and twrp is working.

to find out install disk info and copy the details about your partitions (via the share symbol).

also install AIDA64 then go to "system files" (?) and click on build.prop and copy the information there. do the same for /proc/partitions.

i will check the similarities.

nevertheless you could try to boot (!!!not flash!!!) the recovery, just to see if it boots at all (if yes and partitions are the same, it should be save) as you do not flash it, it doesn't hurt your device but do not use it in any way.

because i'm not an experienced developer...and i don't know if it will break at one point or fails in any way (i didn't build it from source, just modified twrp from yoga tab 3 pro).
so if you only boot it, stock recovery will still be there and you could flash stockrom if nothing works at all. I must say I feel quite comfortable this way...use twrp whenever i must, but have stock untouched.

on the other hand, so far twrp worked quite well for me

if you dare flash it, i won't take responsibility in any way.

secondly, doing ota update should be a lot easier with stock recovery.

hope you see my points!?

funny question, because there's no satisfying way to back up everything without twrp or root! it' s the main reason why i started to find a way for root and 'porting' a custom recovery. now i can use titanium or whatever tool to back up and of course twrp to back up all partitions.

back up what's possible.

I've not had a chance to try the twrp yet but will give it a go but in the mean time.

oh damn, could you please get the info about partitions from disk info again. the most important partitions are missing...like boot, bootloader, recovery, ...
just go to settings and make sure that you check all the following settings (see the attached screenshot):

show mount path
show partition name
show file name
expert mode
unmounted partitions
devicemapper partitions
temp. filesystems

partitions are vrtually the same...just try to boot it. i think there's a good chance it might work, if it starts try and test it...e.g. backup and restore data, see if terminal works and so on...
if yes i think you are good to go

but as always....no guarantee!!!
