THANK YOU for this thread.
I tried it about ten times and it didn't work.
Always got this annoying "TEE PL failed with -19"-message (like others here too). Don't know what this means. But then I looked for another SN-Writer-version and so I installed the latest one (v1.1916.00) and SURPRISE...suddenly it worked and I could read "PASS", yeah.
Now I can see my real IMEI again on my phone but the red annoying Tee and Google text is still on my screen.
Asking myself if it's due to missing one number in my MEID (it just has 14 instead of 15 numbers because you just can insert 14 with SN-Writer).

So next step: Get rid off this horrible big letters and don't stop trying...
Wish me luck! ;)

S3 Pro Non-EU
Windows 10

I'm in the same position, with the TEE PL failed -19 message. I have tried many different versions of SN Write Tool and also flashed various ROMs, including the Euro ROM previously mentioned. My phone has been like this since October and I feel my options have been exhausted. Thanks to everyone for the information they've provided

I've also tried connecting the phone through Maui Meta Version 10 software. It will always fail at "Connect to MD" step.

I've tried using different USB ports, USB data cables. Re-locked the OEM bootloader.

Honestly with SN Writer v1.1916 I just were successful in restoring my IMEI and MEID but the 'red text problem' still exists.

Would be a big help if Bencebacsi could tell us what this "TEE PL Failed -19 Error" is about.

My smartphone:    Umidigi F1 Play
ROM:                   2019090318_g38v71c2k_kw_f1_play_eea
SN-Writer:          SNWrier_1828-4.0.0-vturkey_F1_EEA

It's always the same procedure:

I start SN Writer turkey version (in my case the european one) and do the settings like recommended.

starting program with recommended settings

Then I enter my correct IMEI 1+2 and MEID.

entering correct numbers

I click ok. 'Start searching preloader com port and handshake...' appears on my screen.

after clicking ok

Now I connect my powered off phone via usb to the PC. I hear the 'connection noise' and after about one second the 'disconnection noise'.
The program now says 'Start searching kernel com port and handshake...'

waiting...

After about 5 seconds I again hear the 'connection noise'
(now sometimes the phone switches to Meta-Mode, sometimes it doesn't...nevertheless, the following result is the same)
The program steps to 'Searching kernel com port and handshake OK.'

waiting...

And after 5-10 seconds I get the FAIL message and always 'TEE PL Failed -19 Error'.

...bad result!

All in all I tried it more than 50 times, used different USB-ports and all officially existing F1-Play-ROMs.
Unfortunately with no satisfying results.

Would appreciate it if Bencebacsi or someone else could find a solution.
As a little thank you I include you in my prayers before I go to bed. ;-)

Thanks in advance!
