[help] Lenovo Z5 Chinese room and updates

[Twisted Mind]

Hello , just to share my experience during flashing stock rom firmware base on the procedure that given or post on this site. The 3 needed (Qfil ,zui firmware and step by step) the flashing was not made successfully because of the following problems, during qfil configuration theres another options there : firehost program setting :download protocol there is to choices to consider 0-sahara and 1-dmss i think which not same on the tutorial that was share and then during the final step which is to download theres prompt on the bottom box tell: Download fail: Sahara fail:QSahara server fail: Process fail. Please help me to fix this so that i can back my firmware to stockrom so that the updates app will appear.

i did a quick search on sahara fail and there is a thread about ir for lenovo zuk phone
https://forum.xda-developers.com/lenovo-zuk-z2/help/sahara-fail-help-tried-everything-t3624264

So, you can try few options from that page.

Is your bootloader unlocked? I would imagine it is if you dont have stock firmware, but still.

I locked the bootloader through fastboot and adb you can find it in the russian link provided:

As i said, personaly, i would leave it rooted as i personaly need root. I would update the phone with update.zip packages downloaded from sources like 4pda. Maybe, we will even post here future updates.
If you really want to unroot, you would have to see how was you phone rooted. You have to find it somehow. Most common are supersu and magisk. If you have apps for one of those, that is how it was done. Supersu app should offer the way to unroot in settings. I dont know about magisk, but i think it should be similar.
If the seller used something like kingroot or other auto root apps, maybe there is a way do delete su files from folders (you can google this).

OR, as the final alternative, there are ways to hide the root from apps.

Once again, i would not bang my head too much if manual update works.

Hello buddy,

Thanks, I'm already in version 3.9.200.
But I can not download the update of the Russian forum, you have to register.
When installing the rom the phone is rooted and with the bootloader open.
It is normal?

 

[olyolyoly]

I bought this phone from banggood and when i boot it up it states it has an unlocked bootloader. Does that mean its rooted already?

I like this phone but having a few teething issues. Currently on 3.9.075 st for ZUI version but would love to get to V4.

Current issues im having are as follows...
1. Notification LED (i can see this has been resolved previously from comments in this thread)
1. When a notification comes through the screen doesn't light up so i then have to press the power button to see it. Is there a way to force it to light up on a notification?
3. Sometimes app's won't connect to the internet unless i have the phone unlocked and that is after changing the battery settings. For example Watsapp Web will only connect on my PC if the phone screen is unlocked and active. So its as if the app's aren't passing data back unless the screen/phone is in use.
4. Some apps don't seem to create notifications even though i've changed the OS settings to allow notifications and i know those app's create notifications because they used to on my old phone.

Can anyone confirm if these are resolved in v4?

Thanks

Is jd2018 Legit

This is the link
mirrors.lolinet.com/firmware/twrp/jd2018/twrp-3.2.2-beta1-jd2018.img

You need to install ADB and Fastboot on you computer
put the img file in the ADB folder then open CMD as administrator navigate to the ADB folder and write this command

fastboot flash boot twrp-3.2.2-beta1-jd2018.img

you enter the ADB mode buy pressing the "Vol -" button while turning the phone on, the moment you feel the vibrate of the phone turning on you leave the power button and press it again quickly.

#

So just to clarify, is twrp by codename jd2018 the correct model for lenovo Z5?

Hi guys
Somebody in the Lenovo CN forum was able to flash the GSI of AOSP 9.0 taking advantage of the project treble compatibility of the z5.

Thought i would share this, My phone doesnt have unlock option for bootloader in Developer options.

Go to system -> About Phone -> ZUI version then tap it a few times. Developer mode should be enabled by then

Yes these problems are resolved in v4 (and in 3.9.200 too).

 

[Twisted Mind]

I dont have either. I believe it is the android security feature rather than lenovo's thing.
Apparently, it dissapears for 7 days after flashing or updating the phone. If you did OTA update itshould be it.

I have the same problem. On top of that, afte7 days, option did not reapear . I can also see many otherpeople with different phones having the same issue. There are some rules people set like don't restart phone and such, but that is a load of c***. "Feature" does not work properly and that is it. Playing with dates did not help me either.

In the meantime, i did another upgrade to zui 4, so new waiting period for me.

Go to system -> About Phone -> ZUI version then tap it a few times. Developer mode should be enabled by then

i meant to say the option for OEM unlock is missing within Dev options.

How to re-lock the bootloader?

Glad it helped! I'm in the same situation, tampered multi-language rom, but didn't have the time to flash it yet, will do it tonight.

@CactusJack69, was your bootloader unlocked?[/QUOTE

Originally my bootloader was unlocked but after i flashed the stock rom i also locked the bootloader since OTA updates wont work with an unlocked bootloader.

Hi CactusJack69, how did you re-lock the bootloader? I can't find the way to do it.

 

[WrightStuff]

This is what doesn't make sense - I have copied the download to the root of Internal and 'SD Card' but the 'System Update' tool doesn't see it.

This is the original .zip file as downloaded, then renamed, yes?

Ok I'm in the same position, phone arrived with bootloader unlocked. Want to upgrade to ZUI 4.
I've copied the update.zip to the root of the phone as described on the russian 4pda forum.
What exactly is this 'system update' tool that I need and how do I access it ?
Russian 4pda forum is less than specific : "Go to System Update , in the upper right corner click on the three points and select "Use the install package update" ?!?

Thanks all!
