Since i bought this phone i haven't updated it, and now i want to update my version is 16.0622.1906.19
I tried to install latest version but it failed to update?
You will need to install the updates in order from your version to the next.
EDIT:// I can't see your version on here:
This is the version
The download page is here:
From the download page, download the fololwing firmware files and place it in your root directory of Internal Storage. The system should detect the files. After each step, check to see if you have upgraded.
The upgrade versions you should follow are (Please don't use anything that says CN as that's for Tencent/Chinese models):
(After this stage, you should be on Android 10. Try the FOTA again to see if you get anything. If not, continue with the below versions)
This is the current version
Read my previous post.
One last thing, the first two updates that you have mentioned should i save them both and then update or do one by one for every version that you've mentioned?
Do one at a time to be safe.
You can download them and place them in a folder and then move them to root folder 1 by 1 when you are done with the previous one.
Normally, if you still have this version, then it's highly likely that it says tencent on the phones back. If it does, then you need to find help at XDA forum on how to update your phone. Tencent phones are not supposed to have the WW ROM so there's no official support for this combination.
