[Q] Sim network unlock error fix?

After porting a Custom Rom made for N700 or the international version of the GN2 I am getting a sim unlock network error.
Is there a way to fix this problem?
The rom i used was Android Revolution HD 8.0.

Anyone can help? Maybe i should unlock the phone?
The problem is this is the sim card that came for the device, so its not unlocked, and its the same network.

Yeh i fixed my own problem.

F180K works only with rom F180K10H_00.kdz

Hallo all,
I have a silly question for anyone has time to lose: I have a LG-F180K, the OptimusG korean version. Why can I only use the rom F180K10H?
I tested several configuration and official roms, mixing my backupped baseband and roms, official OTA. but my phone works ONLY with F180K10H.
For example with the others official LG's rom mobile network doesn't work (I can't make calls!!), wifi works. Restoring the baseband (img) works mobile network but wifi not.
I tested the official upgrade F180K10H->F180K20C/G/I without success.
Ideas?

same here
i had exactly this issue.. did you find any solution? thanks!

For now I'm on ICS. Unfortunately I didn't find the reason, but I think it is the baseband...

I noticed that if you dial 3845#*180# you gain an hidden menu. If you have jb installed maybe 2G network is disabled. Can you check this?

The modem menu/settings is 5457

S-800 (LTE) devices have Qualcomm modems. Exynos devices have Motorola modems. The radio s/w you installed with the LTE ROM isn't compatible with your 3G radio. That's why it's borked.

I have no idea why calling's working. The way to solve the problem is going back to a P-601 ROM. Throughout XDA they are posts from people that have borked their devices using Wi-Fi, 3G, or LTE ROMs interchangeably. They aren't interchangeable.

try any type of authentications type..
and in the Bearer you can see these options:
LTE
eHRPD
Unspecified..

[Q] Suddenly not able to access 3g connection on micromax canvas 4 with any simcard

Hello Geeks,
I am not able to use 3G internet on my canvas 4 suddenly it stopped. When I switch to '3G' network bars dissapears or even if they are there it does not load the content, phone gets hot (I think its a packet drop issue)
However, if I connect to 2G or WIFI it works awesome. I had extended warranty of mobilestore but they were not able to fix this, so I stopped trying to get it fixed but found this forum yesterday and thought to give a try.
I have used each and every available sim card which provides 3G in india and issue occurs with all, so definitely its not service provider issue. This is observed on both the sim slots
