GT-9305t NOT REGISTERED ON NETWORK/CORRECT IMEI

HELLO EVERYONE.
i have a samsung i9305T i flashed it wth L.P rom then suddenly
my imei went 0049. i tried anything bUt no luck. so i decided to flash a stock one
4.1.2 my imei was back. But when i try to insert my network sim it says.
NOT REGISTERED ON NETWORK . tho ived used this phone before here in the philippines
so im sure it is unlocked.
any help guys.? thank you in advance does my baseband caused the issue?
please help ...

Hi,
I'm not an expert at all but i have a theory :
I think you get a corrupted EFS. You flashed L.P rom so the format of your EFS changed to V2. So when you tried to return to 4.1.2, the phone can't read your efs anymore.
I think the solution is to flash a newer baseband, for example the L.P baseband or a KK baseband.
Read more about efs format => http://forum.xda-developers.com/galaxy-s3/general/ref-imei-efs-stuff-i9300-including-t2393289
Hope it helps.

IMEI and Baseband Unknown HTC Desire 626G+ Dual

I've flashed a recovery.img file of a wrong variant with Official TWRP App and lost my IMEI and Baseband as a result.
Thinking that it'll be fixed by flashing the stock recovery back, I flashed the stock recovery. But it results in nothing.
No IMEI and Baseband yet.
Tried to change IMEI by Chamelphon, MTK Engineering Mode. But they failed.
Deleted the nvram folder too, but nothing seems to be working.
Any idea what to do next?
Samsung stores the IMEI thing in their EFS folder, where in HTC?

I brought my device to a service provider and he repaired my Baseband and IMEI with his Infinity Box and it's fixed then after.
But it now shows CID Error warning! Going on well with this warning so far.

I've, however, already been to this site and tried almost 10 of their custom ROMs just to stay on with the RR-5.8.8 finally. And the cool thing is, custom ROM doesn't give me any CID error.
STOCK one gives always, though. :crying:
Wasn't sure enough if I was supposed to share external links here or not.
Thanks, anyway.

First of all check your IMEI number and Baseband and describe about what stock rom are you used before and the stock rom you flashed later

Imei becomes unknown during flashing custom rom

I have tried many custom roms but when i flash it, my imei number becomes unknown and i can't use my wifi and my sim is not detected. I tried and followed every steps but it happened every time. Then when i used the motorola rescue tool and flashed my own firmware i got my imei number back and sim and wifi are also working. I want to use a custom rom, which custom rom should i use?

I tried with leveno app and I can back it up, but still got null baseband not found. I know I asked from you a lot but is there anyway backup EFS and presit (sorry my spelling) into an twrp backup?
Because even I flash the stockrom, it dosent find IMEI numbers and the carrier

Lost calls sensor and imei serials

I installed pixel experience plus throught twrp as pixel site says in instructions page after installing the new rom i found there is no sim card signal and i found imei 1 and 2 serials
1 set to blank and 2 set to "0222222222"
I fixed it by restore backup from twrp again but when i call someone or someone calling me and i answer the screen goes black i cant use my phone until other side how on call with me end the call
I flashed the original rom from fastboot buft nothing works only getting worse google services stopped and cant complete opening the phone without google setup

so, after flashing pe and it caused issues, you reflashed to stock but it still isnt working?
does the imei show in stock?

do you have the box? if so try and manually set the imei's, I am not sure how to do that but google it, I am certain its possible.

allright, try wiping system, first backup everything, then go into twrp and wipe internal storage, after doing so, flash the stock rom that ur phone came with (do not interchange global (mixm) eea (euxm) india (inxm) and china (cnxm)), everything should go fine
