Hi All,
I've got the Tee Key problem
I've tried all the usual methods to fix it but I do not have factory mode on my phone
I do have root access
I have correct IMIE and Baseband on the phone and the serial number is correct also
I do NOT have an original backup of the phone - stupid mistake

I have these mediatek packages

did you try the suggestion from my response in your previous post? i.e https://www.hovatek.com/forum/thread-324...#pid187751

lew247 · 02-09-2020, 08:38 PM

Yes
Sorry I forgot to mention it
there is nothing called ro.mtk_microtrust_tee_support or anything with tee_support in the both system and or vendor partition

try adding a new line with "ro.mtk_microtrust_tee_support=0" then save and reboot the device, see if that fixes it

Fixed

I had to contact live:3403902729 on Skype
She then sent me a special version of SnWriter that writes the Tee Key and instructions on what to do
It's specific for each operating version I'm told

good work! this was going to be the last resort, also tee key is device specific

Device MODEL number and Android Version specific
I only had to give the model number and android version (BV9800 Pro and Android 9)

Do share a link to the tool and any other file(s) used to fix for others in the same shoes

lew247 · 05-09-2020, 12:39 PM

This is ONLY for the BV9800 Pro with Android 9 EEA version

writer.rar - 79.0 MB

It will work for other versions but you'll need to Skype Blackview first to ask for the Key and they are extremely helpful
