How to install Android 10 on Z5 PRO GT

*edit*

If any of you uploade the android 10 zip elsewhere send me the links and after validating the link ill put it up here

Downloads

ADB+FASTBOOT

Android 10 Zip

TWRP

For starters don't try to just install zip via stock recovery it will just error out (THEY KNOW THAT YOU'RE BEING A NAUGHTY BOI AND INSTALLING IT WITHOUT BEING A BETA TESTER)

Before you start be on latest stock firmware

For starters install adb+fastboot drivers

After that go to your phone enable developer options by slammin that build number

Then go to developer options and enable usb debugging and oem unlock

Go to about and write down you IMEI 1 and serial number

Then go to Magical Link Yes

Yes yes its in Chinese i think

Here's a handy little translation for you

And apply for bootloader unlock image

Download it and save it somewhere you can find it

Now the fun begins make sure to follow as i say cuz otherwise there's a chance android 10 might not install yes its very picky

Make sure you're on latest official ZUI 11.1.021

Now turn the phone off and power it on holding volume down and power button to boot into bootloader

Now its time to unlock the bootloader

Connect the phone to the computer and open CMD in the fastboot folder place the bootloader unlock img in the same folder

Type in

fastboot flash unlock sn.img

and after that type in

fastboot oem unlock-go

Now your bootloader is unlocked

Now you must boot the phone up and set it up with unlocked bootloader (yes this is important)

Set up the WiFi etc

And make sure to set up a pin and fingerprint

After you finish setup turn off the phone and boot into bootloader again (volume down+ power button)

Now flash TWRP

(put downloaded TWRP image into fastboot folder)

And then type in

fastboot flash recovery twrp.img and slam that enter

after its done click vol down few times to boot into the recovery click power button to select

Now when you boot into recovery it will ask you for a password to decrypt stuff (type in the pin/password you set up earlier when setting the phone up and click ok) now it will decrypt the storage

Now there's 2 ways to do this

1st Option

Connect phone to PC and drag the Android 10 zip to the internal storage

2nd option

Drag the firmware to a USB device and plug it in via OTG

Now click install (do not do any wipes)

If you went with the 1st option then select the zip file on internal storage and flash

If you went for 2nd option switch storage to OTG and click zip file and flash

Wait for it to flash

If it errors out that means you didn't listen and didn't set up pin and fingerprint (they are crucial so don't skip them the update somehow relies on them being set up and if they are not it doesn't wanna flash )

However if you did follow the instructions flashing will go well and after a bit it will be done

(Optional)

You can also flash magisk straight after without any reboots

Now back out and turn the phone off not reboot

Now boot into bootloader (vol down+power)

And you will see that your bootloader is locked again yes that's after effect of the firmware flash and fun part is that until you unlock it phone won't boot either cuz you have TWRP installed

Now unlock the bootloader again (scroll up for the instructions) and after that phone will reboot

Now wait few minutes for phone to boot and huzzah you have yourself some android 10 action on Lenovo Z5 Pro GT

(There is a chance firmware can overwrite TWRP to stock recovery if it doesn't just use the instructions above to flash TWRP again)

And that's about it

Enjoy your android 10
