Do you want to update to Oreo? READ THIS FIRST!

[bruneba]

hi, i forgot to install contacts and dialer on 3.1 and now im on 3.5, can i do it anyways?

Yes.. See the first post how to sync google contacts

I tried to update as described, but my phone never wanted to go to edl mode (I was on 3.1.218, bootloader unlocked and rooted and are worked right), so I could not flash 1.9, etc. Finally I made a factory reset (lost root) and updated with the renamed OTA from the stock recovery. Update worked and everything is OK. Now I am on 3.5.316 and happy, but without root this time.

You can easily unlock bootloader on 3.5.

if you aren't already, unlock it and flash magisk with TWRP to root

I worked all the steps as described, everything seems to work fine, except one thing: the google play app (v8.7.50) cannot update (clicking on version under settings does initiate a download on the notifications but when it is finished it disappears, it doesn't install). Any idea anyone?

Hm.. Idk, try to clear its cache and data

Do you have bootloader unlocked?
Maybe it didn't pass safetynet.

Thanks for you reply
I have tried clearing cache/data - uninstalling and reinstalling via app centre.

Indeed my bootloader is unlocked and magisk installed, where the SafetyNet result is:
ctsProfile: false
basicintegrity:true

I have no idea what the first one is but since all my root requiring apps work I didn't pay too much attention.

You just have to install and enable a module to pass safetynet.
But remember to disable xposed framework if you have it enabled, or it will never pass.

After you get both results as true, clear play store data and cache

Thanks, I tried it, now both SafetyNet tests are true but still same thing. I noticed now that under version. Device Certification field is now Certified (before isntalling the SafetyNet module it was uncertified).

Which is the latest Google Play version for 3.5.316? I could try installing via apk.

Idk what is the latest, I'm on a custom ROM now.
Why you want to update it? It isn't working fine as it is?

 

[n0body]

I am just afraid it might be other issues in the future related to google services (e.g. contacts sync). It does work fine though, so I will stick to it for now.

since I installed the playstore with app center on stock rom, I never had any issue with this app, so dont worry

My bootloader remained unlocked after the update as I did it over the 3.1.218 and not from 1.9. But anyhow fastboot mode does not want to working right (just like the edl mode). ADB list my device and I can boot to bootloader, but from here I cannot flash (or boot to) TWRP...

Just search for it on apkmirror

Actually I don't recommend installing other version if yours is working fine.. I remember the time I did that and I got too many crashes on play store..
But it is your phone, so you can try if you want

So, that's a good reason to lock it again flashing 1.9. It should fix this issue.

Force edl mode using button combination.

Turn off your phone.
Press and hold Volume Up and Volume Down button
Connect your phone to the computer with a type-c usb cable
Your Phone is now in fastboot mode (release the keys)
Open terminal (cmd) and type
fastboot -i 0x2b4c oem reboot-edl

Thx for the hint, maybe sometime I will try it, but now I am happy with the phone as it is

Thanks in advance and cheers.

Nope, so far so good.

Thanks for the helpful guide. Just wished the host was not MEGA, I'm at 37% downloading zukpro19 and I already exceeded my bandwidth.
