Hello! I have very big problem, because I don't know what to do now. I accidently did "Format All + Download" while trying manually update ROM from 20201228 to 20210128 on my Umidigi A9 Pro 64GB. After booting I saw two red labels "Unwritten tee key" and "Unwritten google key" on screen and NO NETWORK . I realised, that it's problem with NVRAM and started looking for solution. I tried a lot of methods and finally found SNWriter. It didn't help me. Yeah, it wrote correct IMEI codes, but network didn't appear. Then I found this https://community.umidigi.com/fo ... 9565&fromuid=431168 topic and reflashed my device following it: - Format ALL
- Download Preloader
- Download Other Partitions
. Then I downloaded SNWriter for my model from this topic, successfully restored everything following instruction in first post, but it's still no network, I can't make and receive calls. Interesting fact: in *#*#4636#*#* I can see both correct IMEI's, network signal strength (30-35ASU), SIM CARD number, even Neighbor Cells. BUT PHONE STILL SHOWS "NO SIGNAL" AND ICONS WITH CROSSES... Phone seems to see network, it asks for SIM PIN code, it sees right IMEI's, phone numbers. I think I need NVRAM.bin file from manufacturer. Help me, please, I've tried everything
