Hi all,

I've been using this forum for years and years, always finding solutions to my rooting, rom or whatever problems but I'm getting to the bottom of it with this new one.

Here is the situation :
- I tried to install a ROM, it crashed, got my EFS partition delete.
- I didn't have any backup (I know, I know, I screwed up)
- I asked a friend with the same phone to send me a TWRP backup of his phone
- Now, I have a working S8, but with no IMEI

I still have my IMEI number from my phone that I would like to inject into the EFS partition. Is there a way to do that ? I don't want to change IMEI, I only want to reinstall mine. I'm trying to find IMEI tools to do that, but in a legal way (I know it's illegal to talk about IMEI change here). Or maybe an idea would be to generate efs.img files ?

If anyone has a good idea, I'll take it !

Thanks

You can't. Imei is cert protected. It has to be wrote to the device with a new cert file. Paid service my friend only way. Try flashing your stock firmware with proper baseband and such. Btw imei isn't in the efs like it used to be. That's about all of the help you will find here on it

Hi.

I'm in same case. I losted my phone IMEIs and i'm unable to use my g960F DS.

My 2 IMEIs show only zeros. And restore efs didn't worked for me.

I wrote phone's IMEIs on paper in case with ID too.

I try secerals ways but no success.

I will be good to share the process to have success.

Thx a lot

Ok so the @BIOKNOX account has been removed. Thanks for nothing, industry! 🤬
Can we have a solution to the technical problem, please? (No need to state that looking for official service was a hopeless adventure.)

How can the Problem
"IMEI zeroed out on screen. Original IMEI available on package"
be solved, please?
Official answers welcome. PM welcome.
