UMIDIGI F1, F1 Play and S3 Pro: Repair IMEIs, MEID and Google certificate

chrismelb

Need help - I have an error using SNWriter (Umidigi F1 Play). I have spent 2 weeks and can't fix it so I'm trying this guide.
I have null IMEI so my phone won't work (Wifi and Bluetooth and apps all work), need SNWriter to fix it.
I can use SPFlash tool perfectly.

But when using SNWriter - both version 1.1828.0.0-Tee-v4000 or latest 1.1916.00 - I get this error
FAIL   - SmartPhoneSN::- APSwithToModemMeta_Ex() : Switch to MODEM meta from AP meta fail.
EDIT - I now get error -23 like the user Faysoft posted above. "TEE PL Failed with -23 ". I have read all the logs but can't understand what the problem is.

What does this error mean?
Can anybody help? My brand new phone is useless without SIM card and IMEI.

Sorry but your "tutorial" is completely a misconception with many wrong statements and conclusions. You need to just strictly(!) follow the instructions in the first post and it will work. It's very important to download that version matching with the software version on your phone.
The software of the F1 and F1 Play is perfectly compatible (the fingerprint scanner and everything), except the back camera setup. You can use this tool on any version but you must use the EU version for EU version phones and vice versa.
You were just simply lucky after many attempts with wrong methods but your tutorial is nothing about a solution. I recommend you to rather delete your post.

1. Flash the latest stock ROM in firmware upgrade mode on your phone, not a custom shit or anything, and do not change anything on it.
2. Re-lock the bootloader if you've unlocked it.
3. Choose the appropriate SN Writer TEE version that fits your phone model and region - EU or non-EU.
That's all.

Hello. before, I could manage to change IMEI by secret codes such as *#*#08#*#* . but I can't change on my new F1 Play ( non eu version ). This secret code works out,it opens the page where I can write down the IMEI numbers.  but although I save and it says that it succesfully change the IMEI, it doesn't change in fact. Do you know any other way for F1 play to change IMEI without programme but through secret codes?

I worked the second time, as I had managed to recover the imeis repeated the process only by checking two options, the bluetooth option and the wifi option and configuring it as advised in this post to be generated automatically, if done correctly , the red letters will disappear, they took away my f1 play.

Hello. I tried this code on my new F1 and yeah it is not working, imei numbers are not changing. If you can find any solution can you share?

I have tried using the SN Writer multiple times and my Windows machine always says the USB device couldn’t be recognized. I can use SP Flash Tool (if I hold the Power and Vol +) with no worries. I’ve installed the drivers as specified, but still no dice.

I have an F1 Play and mistakenly wiped my NVRAM partition yesterday when trying to clean up to install the newest OTA. Suggestions would be very welcome at this point.
