Unknown IMEI and locked network after trying to recover

Hi everyone,
Hope you can help me solve this, cuz I'm way out of my knowledge..
My phone broke the lcd and was out of action for a few months.. After I finally got a replacement screen, the phone wasn't working and said IMEI unknown, I've tried to flash a few roms via recovery but nothing. So I just went crazy and flashed it via kies. It worked, the imei appeared but the phone was locked again..
Back to the shelf a few weeks until I could afford to pay for unlock.. When I picked it up, it was unknown IMEI again and the guy at the shop basically told me he couldn't help.
Was he right? I refuse to believe I can't recover the phone.. Can you please help?
Thanks!

Anyone?

Are you sure is that phone imei is not blocked, because provider may block if it is stolen reported.
I had the same problem after changing display IMEI unknown
But somehow it was saved from 'unknown IMEI' I don't know how.
restored efs from previous backup (twrp & philz recovery)
- no imei
I flashed stock
- no IMEI
asop
- no imei
tried different modems
again stock
- suddenly its worked
(some users reported flashing different modems worked for them)

Yes I'm sure imei is not blocked by network. Have a friend that bought a phone which he discovered the hard way it was stolen, anyway, blocked imei by network behavior is completely different.
This is what happened to me first time only valid imei after kies rom update.

If you see imei again, Make a backup using pc, there is a guide in development section. So, you can easily restore again.

Restore IMEI To XT1072

Hi guys
I've looked all over the internet on how to restore the IMEI and I don't seem to be having any luck. At the moment the IMEI under the Android system shows as '0' I and I want to restore it to the proper code that's printed on the inside of the phone and outside of the packaging box. I initially made a NANDROID backup using TWRP but no EFS partition that other phones use was backed up, so I have no idea how I can restore the IMEI information. I'm trying to install Cyanogenmod 13 but I'm disappointed that the incorrect IMEI is showing. I have even restored the entire TWRP backup and the IMEI is still showing as '0'.
Can some help me out here please.
Many thanks
Will

I just flashed CM13 and IMEI came back, but the phone works only in 2G now
(I have xt1079)

Baseband + IMEI Unknown

Hello
I recently lost my s10 and now got my hands on a new one (exact same model)
I thought i was smart and restored a TWRP backup from the lost phone on the new one
I guess the mistake was that there was also the efs partition included in the backup
The rom (newest beyond) works without problems but the sim card is not recognized and baseband and IMEI both show unknown
so i flashed the original samsung firmware with odin but even then i have baseband and IMEI unknown
Did i just screw my new s10 or does anyone have an idea?
any help much appreciated

Anyone has an idea what I could try?
Or did I really kill my phone for good

My guess is that you may have wiped out the new phone specifics, such as IMEI and other things. I'm not sure if you can recover that in some way, or if you need to just find a way to get your old IMEI back. I would probably try to restore my old IMEI if I can (see if you can identify the old one from your carrier's website or something, for example).

I know the original imei, it's printed on the phone but how could i flash that to my phone? Seems to be impossible

There are ways, but they are not allowed to be discussed here on XDA. I've seen Youtube videos that cover it as well.

N960F IMEI repair

imei went to zeros . was fixed online with a new imei. Since then i updated rom and have no signal. I'd like my original imei back or at least fixed again. Had enough of chasing fake apps with passwords and viruses. Any help appreciated. Thanks.

If you have TWRP and a backup you have done via TWRP just do a Restore in TWRP but only restore the EFS - ODM and ODM Image partitions only. That will restore your IMEI.
My note 9 had all zeroes and I could not use it for over 9 months (purchased a replacement). Found an old TWRP backup while cleaning out my PC and this fixed it straight away.
Always do a TWRP backup and ensure you keep a copy of it off your phone.
