I just tried one wireless charger that i have and it didn't work. Other than notification settings, no other settings say that it supports it.

Dont know if there is some compatibility that has to be met. My charger is rated at 2A so it should have been fine if it was supported.
[Android Q&A, Help & Troubleshooting] CactusJack69:
I hope the phone supports wireless charging and that they have just disabled the feature for now and will bring the feature into the market as an OTA update in the future. Would love to have wireless charging with this phone

Since I have sold this phone, can anyone make a back-up of all the files from my mega link and post it here for whoever needs it? I want to free up the space taken by these files from my cloud, and it would be a shame if they'd be lost. Thanks!
[Android Q&A, Help & Troubleshooting] Twisted Mind:
I have imported it in my cloud

https://mega.nz/#F!ndhjkT5T!TZ2Gy-HJhJLO_j_GpaNf4A.

I will leave it there for a long time. I will also upload it to cloud.ru later.

One question though, the docx file is named steps for rooting. Is that the tutorial to root or to flash firmware? I would say that this is flashing.
[Android Q&A, Help & Troubleshooting] vlad.spatariu:
It's for flashing, but that's how it was translated. Definitely for flashing though. You can find a step-by-step on how to root on the russian site I posted a few pages back. :)

Have any of you received the ZUI 4 update for lenovo z5 through OTA? It seems that the russian site provided above already has firmware for ZUI 4 update but when I checked through OTA it still doesn't have any updates.
[Android Q&A, Help & Troubleshooting] Twisted Mind:
not yet, but i am imaptient to get it since it includes led notification and reposition of software buttons.

I will not use the russian version just in case and will wait for the official one thorugh system upate.

I hope that updating will not bring back chinese apps i uninstalled.

EDIT:

I have looked at those flashing instructions and you dont have to use that chinese version or install anything. QFlash is standalone and can be downloaded separately

https://androidmtk.com/download-qualcomm-flash-image-loader-qfil

QPST is used only because it comes with qflash

https://androidmtk.com/download-qpst-flash-tool

Also, worth mentioning is that you should not flash anything but stock on locked bootloader. So, no multinalnguage unless you know how to unlock.

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.
[Android Q&A, Help & Troubleshooting] Twisted Mind:
Where did you download qfil?

If you downloaded standalone, try the one from qpst installation since it might be different version.

Also, did you enter fastboot mode (or whatever mode is required) with power and volume buttons?
[Android Q&A, Help & Troubleshooting] mugwump00:
Hello all - got a Z5 in the UK - great price for awesome hardware (it's going to sell well), but the supplier is useless - it has had the boot loader unlocked prior to me receiving it, so the System Update app refuses "your system has been root, we are unabe to provide the latest version...". I've d/l the ZUI4.0 from the Russian site to an SD card but SU says "There is not update package..>".

I realize I'm a newbie wrt Android flashing etc., and I'm reading everything I can, but can anyone help guide me to what I need to do to re-lock the boot loader, or get the offline installer to work? TIA.
[Android Q&A, Help & Troubleshooting] Twisted Mind:
For the offline udpate, you have to rename the zip to update.zip

As for locking botloader, it might not be the best idea if your recovery has been updated as well as the phone rooted.

Basicly, this is how it works when you want to root

1. you have to unlock bootloader. Boot loader is loading boot image. When it is locked, it checks boot image and recovery image to see if it is the stock one. If it is not it means that it is modified and it does not let it continue.

2. in order to flash anything like magisk or supersu, you need custom recovery image that allows flashing unlike stock images. So, you change the stock recovery to custom like TWRP. So if bootloader was locked, your phone would not boot after this.

3. once that you have these two done, you just need to modify the system partition to gain root access or what ever. Maybe even install whole custom rom. This is done by flashing zip files that make the changes to system.

I wrote all this with a reaseon.

If you want to revert to pure stock, you have to flash the stock image and lose all data OR uninstall SU (super user) binary that allows root access. If you want to uninstall, you have to know which one is used and there are lots of these. Most common is superSU, but...

Personally, i like root and would just flash the dwnloaded update package.
[Android Q&A, Help & Troubleshooting] Choi02:
Hello,

I just followed from what is being post regarding on flashing of stock rom here. Also the app that i had used was the thing that uploaded here on mega app.

Is there anything to do first before im going to flash the firmware, i mean if the phone will be need to root or unlock its bootloader first? Because apparently my phone says that its bootloader was unlock by turning it on theres a message promt that my phone bootloader was unlock. Or theres another chance to upload again the app that you used and given us the simple and easiest way for flashing?( i mean the step/ procedure) , thank you for your kind assistance

And regarding for the fast boot mode sorry im not aware from that thing. I just did is the final step that turn off the cp press the volume + and -,then put the usb cord to pc then let go,then the loader qualcomm will appear.

i did a quick search on sahara fail and there is a thread about ir for lenovo zuk phone

https://xdaforums.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.
[Android Q&A, Help & Troubleshooting] Choi02:
hello bother,

Thanks a lot for your response and help. My phone now back to stock firmware 3.9.200ST, however the phone still rooted and unable to update it. May i know even the my phone was rooted is there another way to get an update? how? and please share the file . Thanks !
[Android Q&A, Help & Troubleshooting] Twisted Mind:
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.

[Android Q&A, Help & Troubleshooting] 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

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 :D. 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.

[Android Q&A, Help & Troubleshooting] WrightStuff:
To give something back to this thread that really helped me out :

I received the z5 and as others have reported it was boot loader unlocked and had some non standard android build on there. It kind of worked but was pretty rough. A lot of the transitions and process switching was very lumpy.

First I ensured auto updates were enabled and a WiFi connection was defined.

Then I manually copied the ZUI 4 (update.zip) to the root folder on the phone :

https://translate.google.com/transl...0168,15700186,15700191,15700201#entry76144132

Then I reflashed back to OEM 3.9.200 using QPST and these files :

https://mega.nz/#F!ndhjkT5T!TZ2Gy-HJhJLO_j_GpaNf4A

Unfortunately after the flash the phone was malfunctioning.

It booted to a flashing home screen, with all icons missing :(

-But- because it detected via OTA that an update was available it popped up with a notification. I was then able to click on that and manually install the update.zip from earlier.

Could not install OTA at this point because the phone was still rooted.

After installing ZUI 4 the phone rebooted and is now working perfectly!

This might help you out if you get in this situation.

Everything is a lot smoother, switching, minimising etc.

U Health app doesn't allow you to enter a UK phone number.

Right swipe from the homescreen still in Chinese.

Play store not provided as standard, so you will need to download the .apk for that.

Lots of extra apps in Chinese, but I have no idea what they are!

In the seller provided 3.9.200 ST build the update option is not available but once you reflash to 3.9.200 in the mega.nz link the update option is then available (see my previous steps to then upgrade to russian ZUI 4).

The reflash instructions are ok but some of the filenames are slightly different.

Just be aware if the reflash doesn't work for you I won't be able to help as I learned just enough to get my phone done!

This includes 3.9.075 and 3.9.200. You can ignore L78011_XXX_3.9.075 as you will only be using L78011_XXX_3.9.200.

I also didn't use zui_XXX_3.9.075.

2. Download the ZUI 4 update.zip from google drive : (this is linked to from 4pda - aka the russian site. I've given the direct link here to make it easier)

https://drive.google.com/file/d/1zIE54WIXwiK5-LLtPju01HcMQybJuiad/view

3. Copy the update.zip to the root folder on the phone.

4. Enable wifi connection and enable auto update.

5. Install QPST and Reflash phone with 3.9.200 using QPST/QFIL - follow steps-for-rooting.docx

6. When the phone reboots it should reconnect to wifi and pop up a notification saying update available.

7. Select the notification, then hit the 3 dots in the top right and select 'Use install package update', this will install the update.zip from the root folder.

8. Hit reboot when prompted.

9. Phone should restart into ZUI 4. I think there is a menu in chinese asking about cloud storage for the first reboot, can't remember which option I picked you will have to work this out yourself ! (use google translate on another phone).
