UPDATE: an unknown hero packaged a TWRP-flashable version of both the #Oreo modem firmware and bootloader and now I have my SIM card back.
If you own a #Samsung a5y17lte and lost both #IMEI and baseband after updating to #LineageOS 16 feel free to reach out to me, I'll be glad to share what I learned.
Hi, I have the same problem and have been searching for ages to solve. Please will you share your findings of I may also fix this Lineage mess up.
Thanks I'm advance.
@Sparky hey, I'll share the flashable package with you later.
Just place it in your phone main storage and boot into TWRP. Then flash the zip package and you're good to go.
NB. The package offers two options, only the Oreo one worked for me, but your milage may vary so keep that in mind if the first run doesn't work.
@Antanicus Thanks Antanicus. Appreciate your assistance. I found an unofficial build of Lineage 17.1 for our phones and flashed that a few mins ago hoping that it would fix the SIM issue...but guess what...lol...I don't need to say it. Will wait for you to share the zip files. If you are interested you can check it out here https://www.getdroidtips.com/lineage-os-17-samsung-galaxy-a5-2017/#Download_Links
UPDATE 2: I also found a flashable zip that installs #UnifiedNLP as a system app without a hitch. Feel free to ask if you are finding it hard to peoperly set up geolocation on your device
