Simple

Flash ZUI 1.9.044 which is for Z2 CN model. This ZUI version is very important.

Download link 1
Download link 2

Password if asked is: ask.lenovomobile.com

Then flash latest CN or Indian ROM of your choice through QPST.

Your bootloader will stay locked and you can use OTA updater app as a virgin phone. (With re-locked status, you could not use OTA updater app and had to rely on notification to update.)

Warranty should be restored for Indian users.

Fastboot status:


Thanks to members of this forum who discovered this accidently. So backup that 1.9.044_ST and keep it safe.
Enjoy.

Why don't you try and confirm it?
Because I am stock and won't void warranty just to prove the original thread poster if it works or it doesn't.

Anyone that has rooted the phone and is on twrp can easily try this by backing up their cellphone, flashing both qpst files as you mention and confirm it stays on locked. After that they just unlock bootloader and restore backup

Confirm too. Only 1.9.044 will set you back to locked, newer won't
I originally noticed this, and can confirm this.

> Warranty should be restored for Indian users.
Is not all that certain, since you initially send your serial to lenovo to get the unlocker.
Guys, another question, did you came back from 2.3 chinese or 2.011 Indian.

Thanks

Hmm i did that before the Indian release.
buggy international -> 1.9.044 -> 2.1 chinese -> unlock/root -> brick -> 1.9.044 -> 2.1 chinese -> unlock/root ; haven't switched to indian or 2.3 yet.

They should offer warranty because sending request for boot loader unlock file doesn't mean you actually flashed it.

Can I update Z2 Plus (Indian ver) having ZUI 2.0.111ST with this ROM?
My Z2 has security patch of August 1st 2016.
When I clicked on System update in Settings, after brief refresh it is showing No updates but when I click "Details" it is showing "Failed to access the release information server, please refresh again", which is failing everytime.
  1. VoLTE is not working even though enabled.
  2. With no background apps it is getting stuck (blank screen, continuous LED notification ON), once in two days.
  3. Bought & using from 45 days now. I reset 3 times & restarted when it crashed ~15 times by now.
Please help me with this, neither Customer telephonic Service nor Service Center is not responsive here! Anticipating a positive response.
I can download and update this ROM from recovery mode? What is the procedure to update? Thanks in advance.

Hyderabad, India
Hi you can flash newer version via QFIL or Miflash
stock chinese rom is good
i guess volte also works

dont flash via recovery. flashing via MiFlash is the safest and easiest
