wifi problem - just reflash kernel and wifi will work ..
for baseband - if you can call that is not poblem with "unknown baseband", i have unknown baseband and everything work good

I'm not familiar with the ROM you flashed, but most likely what you experience is due to incompatible baseband and RIL. When you flash a ROM the baseband remains the same, so you are still on an old GB baseband, but your RIL is made for ICS. Flash a v30 baseband and things should work again. See the baseband overview thread here.

Need Help "LOST IMEI and Baseband Unkonwn"
I was using Euporia 5.0.1 on LG 4x
I received update notification and I downloaded Update.zip ( which included to 5.1)
By mistake i flashed the zip directly from CWM ( without Formatting any partition )
after restarting there was no IMEI
Following things I have tried
1) Trying to flash Original V20C KDZ. via LG Flash Tool. ( I think it checks for IMEI , and that's why stuck in between)
2) Use LG Software Update tool. ( also can't progress with IMEI)
3) Flashed Original V20c Flashable zip from CWM (But it didn't restored my IMEI)
4) Contacted LG Service Center, and They say You need to change whole Motherboard. ( I was Shocked to know that )
:crying:
If anybody went to same problem. and resolved .
Please Guide me.

I dont think that fleshing update.zip had anything to do with losing IMEI since you cant update 5.01 to 5.1 without wiping u will just have many bugs but u wont brick u device.I think it is hardwer problem my friend on his lg 4x have similar problem (no IMEI and cant connect wifi to any network).

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.

Hope it helps.

Help needed:strange S3 mini became sim locked after installing custom rom

Hello ,
I hope that someone could help me !
My friend ask me to mod a galaxy s3 mini i8190n .
It was bought in UK (used from a shop) , but from the splash screen i saw that it was original from french (SFR carrier).
Before do everything i checked the IMEI displayed and it was the same of the sticker behind battery (it was ok) and i saved the original firmware code .
The phone was working properly with an uk sim , so i didn't think that it was sim locked .
I rooted the phone and made a backup with CWM.
After i saw the last release of cyanogenmod 12.1 , i flashed TWRP and CM12.1.
I didn't try with sim inserted at the beginning . After all wipes the system was unstable (reboot , black screen etc ) .
So i tried to flash the Resurrection Remix (last release) that worked better .
With the last rom i tried 2 sims (perfect working in other two phones) and both are not recognized (no sim icon).
No message for unlock the phone on starting was displayed!
I thought at that moment that probably the phone could have some problem with flashed roms.
I decided to reflash CWM and restore the original firmware from backup . The problem persisted (no sim ).
So i found the original rom on sammobile and flashed it . No sims recognized as well !
Imei was the same with all roms , so i think that the EFS folder is good !
I read a lot and discovered that the sim unlock is stored in a protected memory area , so i think i couldn't delete the unlock ... If it had been unlocked before being sold. Am i right ?? And i would like to exclude an hardware problem .. because the phone was working properly before the modding!
What could I do for resolve this problem? The phone is not mine and i'm so sorry to have made a mess!
Thanks in advance for any suggestion.
This is the orginal firmware version

Just wondering if you resolved this problem. I had the same problem - no SIM working on any custom ROM. I could only fix it by re-flashing stock Recovery in Odin, and then Re-flashing stock ROM also in Odin.
