Hi,

I think it's pretty much the same problem as described here : https://bbs.blackview.hk/viewtopic.php? ... st#p879695

As a matter of fact, it is happening to me too, after flashing the ROM provided on this forum, I got TEE: *red chinese characters* and Google: *red chinese characters* on the upper right corner of my screen. I tried following the tutorial that can be found in the link above, but SN Writer (V1.1828.0.0-TEE-v4100) fails with the error : TEE PL failed with -19

I looked into the log file of SN writer, here is the end of the file when the error happens :
 [08 26 20:41:33][INFO]<__kpha_init>: Program Secondary certificate.
 [08 26 20:41:55][ERR]<trustkernel::Uploader::post>: perform_failed: 7
 [08 26 20:41:55][ERR]<trustkernel::Uploader::upload>: Failed to send upload device with: -1

 [08 26 20:41:55][ERR]<trustkernel::VTurkeyLicenser::issueSecondaryLicense>: Upload failed with -1

 [08 26 20:41:55][ERR]<__kpha_init>: Device production processing failed with -19
 [08 26 20:41:55][ERR]<KPHA_Init2>: __kpha_init failed with kr = -19

I was wondering if this could be related to the Googlekey file that we have to enter following the tutorial, but since I couldn't find any information related to this TEE PL error, I don't know ...

Also, I read somewhere else about using a newer version of SN writer with no tee stuf, but the method requires an attestation key file (.bin) that is not present in the ROM zip file ...

I hope someone will be able to help, and that this post helps others too ...

Many thanks in advance.

Hello, I've got an issue on my BV9500 Plus using that ROM. It shows in red color:

Tee: [Chinese chars here]
Google: [Chinese chars here]

..on the top right of the screen and I can't get rid of it...
Also once opening google chrome for the first time, or any google search field on the system, it asks if we want google, something Russian or another thing I can't remember

Any help would be greatly appreciated!

Hello, could you please describe this question clearly or shoot one pics?

Sorry I thought I'd have an email when there is an answer to my post....
Anyway, I can't send pics and now I'm running a more or less stable LineageOS as it was the only one I could install and make work on my BV9500+. Tho I can't use google pay and other stuff requiring SafetyNet to pass. I would love to restore original OS but I cannot remain with those red labels on the top right. Apparently not only me is getting issues with restoring original OS...

Hello, sorry for the inconvenience, please contact the after-sale department support02@blackview.hk

Thanks, nice to see that both by email and here BlackView team is very responsive, really appreciated!
Now I need the latest original firmware (for France if it differs per Country) haha!

Any information?

So after contacting by email I got some tools not working and I still have the red thing on top right even after restoring my IMEI and all the rest...

Hi.

What tutorial did you follow to install lineage os? I've searched a lot and I did not find any that would actually work.

Thanks in advance
