Due to your ROM that you used in your phone has problem with 3G, in my opinion. I used ROM made by Docco (on tinhte.vn) and I realized that it's ok all the time. You can register 3G by sending a message to the operator and can use 3G (no need config).

will you please give the link of rom which are you use on your lg lu 6200
thanks

I found this answer from an another thread.....
IF the phone is rebooted in airplane mode, the base band and IMEI is unkown.
Putting it out of airplane mode and rebooting, fixies the issues.
If it still does not, fixing permissions from CWM recovery works for me.
This thread also will help you to fix this Problem....

How to do Activate HTC Incredible 2 Verizon and unlock code

Hi guys, rite now HTC Icr2 in vietnam and china, they could unlock already, today i try to translate from their website, i hope it can help u guys.
source from vietnam:
"Vấn đề là mình cần phải set máy về CDMA Sfone để máy ko roaming từ Verizon qua nữa thì sẽ by pass được Activate.
Ở đây, tool ##778 ko hiệu nghiệm như đối với Incre1, do đó, mình đã thử với CDMA Workshop 2.7.
Trình tự như sau:
+ ##3424# để đưa máy về chế độ Diag
+ cắm cáp usb vào máy, tải HTCDiag driver để nhận diện.
+vào run, chạy Devmgmt để xem USB nó nhận là COM bao nhiêu.
+chạy CDMA Workshop, connect tới COM Port. Có thể mình phải send SPC (000000) để edit thông số.
+set tất cả các trường thành 1 số sfone, ví dụ số của mình 0959408599
+set MCC, đại loại country code gì đó thành 452
+cả NAM1, NAM2 mình đều set về số sfone giống nhau (Chỉ cần số sfone bất kì, ko nhất thiết phải số thực hay activate gì lên tổng đài cả).
+write
Khởi động lại máy và ok.
p/s:
ngoài ra, sau khi activate được, mình cần phải order code (số imei tìm trong status của máy) và nhập vào. Máy này ko tự hiện lên chỗ nhập code như dòng khác mà phải vào Setting -> Security -> disable sim lock để nhập code."

we have to set phone go back to CDMA Sfone, to stop roaming from verizon to phone, it helps to by pass Activate
##78 works for Incre 1, i try to work with CDMA workshop 2.7:
Follow this step:
+ ##3424# to let phone go to mode Diag
+ connect USB to phone, download HTCDiag driver to recognize
+ Go to "Run", run Devmgmt, let see our USB in what COM port number ?
+ Run CDMA workshop, connect to COM port. May be we have to send SPC (000000) to edit
+ set up all of them same phone number, ex: my cell phone 7144171411
+ set MCC, like country code whatever to 452
+ All NAM1, NAM2, i set them as same number sfone ( u can set any sfone number, not neccesary, its real or not)
+ write
reboot , done
p/s:
after done activate, if u want to find IMEI code thats in status of phone), if u wanna go to unlock code mode (Setting -> Security -> disable sim lock)
i hope this will help u guys, plz let me know, if u can do it or not, i am looking for more information in asia
awesome! i hope this works. i don't have the smarts to try it :/ hope to hear someone try it soon though!
Hum interesting ...
So this is just to unlock the GSM capabilities?
Sorry guys , no free cheese for today, you cant unlock gsm module without nck unlock code , it cost 20 bucks or so or someone told here that if you have no unpaid bills you can call vzw and theyll provide you a code for free. Hope xtc will support it soon and will full unlock em..

Not really. I have to have vzw account only if id like to obtain this code for free, other way is to buy a 8 digit nck code and unlock it as any other phone.

If u have vzw account u just unlock 1 phone, how about if u have more than 1, and u have to pay money to buy the code, waste ur money
Moved to proper forum.
So is this to use it as a global phone for free?

I believe that it is locked for US carriers; however, if you were to travel and use an international provider, you can place their SIM card and you should connect. The DInc2 is a world phone minus T-Mobile, AT&T, Sprint, etc. capabilities.

I can't make a call , i can't use GSM/UMTS mode ,I'm not in US
I live in Vietnam .
I try Xtc clip unlock my Incredible 2 but doesn't work
Some of people on forum met same problem as I , but there has been no solution for this ?
Google search : http://androidforums.com/htc-droid-incredible-2/327419-sim-unlock-issue.html
No solution
In fact ##3424# makes the phone to skip activation procedure and all other settings like data sync, google acc and so on. All the rest of this procedure was performed precisely, but after hard reset the phone still asks for activation to be made.
I got my unlock code from global support using the stock Vivow 2.3.3 you go
Settings>>> security>>>>> disable sim lock
Enter the code
It will then reboot
I have confirmed with a ATT sim
I can go back and forth from VZW cdma and gsm ATT and make calls text
Someone already mentioned it how ..... You are limited to EDGE only
Good luck guys

H and H+ (Chinese rom)

Hi.
I have a question about 3G mode: when I'm surfing on internet or I'm downloading a file with an european rom (Example 111,112,114) I see the symbol H+ but if I make this with a Chinese rom (Example 116, 117) I see only the symbol H.
Is It only a visualization problem or with the Chinese roms the H+ mode is not working?
Can be solved this issue by editing build.prop or by copying from any european rom a specific file/folder?
Thank you very much
P.S. B117Sp01 is working very fine

LG G3 D855[v20g-SEA-XX]: 4G available on Menu but not connecting

Hi fellows, I recently acquired a LG G3, an astounding phone, but then I realize it doesn't connect to 4G/LTE network. I'am an advance user and I' double checked APN, Carrier Service, and all configuration staff, also I had read a lot about troubles people is having with this, but my trouble is less common, I had the 4G/LTE option available and enabled in Mobile Networks menu, but my phone just doesn't connect to 4G/LTE it just stays in HSPA. Well, I' have tried the most common solutions and none works for me, here is what I've tried:
1. Go to hidden menu: 3845#*855# -> LTE Only -> Modem Settings-> RAT SELECTION->GSM/WCDMA/LTE auto (this just restore my HSPA and cellular connection when solution 2 fails)
2. Go to hidden menu: 3845#*855# -> LTE Only -> Modem Settings->LTE Band Selection (here I switched to every band, some give me a Success other Failed, nevertheless I got no signal service unless I do solution 1)
3. Change build.prop telephony.lteOnGsmDevice from 0 to 1( it changes it, but after reboot it comes back to 0, nothing happen )
4. Renaming LTE Config apk and rebooted(I rebooted then the it says the phone is upgrading and after that nothing happen)
Now I'm sure it is something related with the phone region and my current location because my firmware has suffix ASEATN (Asian)and I'm living in Ecuador currently, but I'm skeptic about the risk of flashing and changing the region.
Can anyone give some guide or advice about my specific problem, I'm willing to do advance user staff. Thanks in advance!
These are my phone specs

I have exactly the same problem.
I'm from Peru and the model is D855P. I used to have 4G LTE when I first bought it, but after installing CloudyG3 (Lollipop), I was never able to connect to 4G again. I have the option but it never really connects. I have to set it to 2G/3G only.
It's curious that when I traveled to the U.S some weeks ago and used an AT&T SIM, 4G LTE worked perfectly and back in my country, it does not.
I tried changing LTE bands using this method http://forum.xda-developers.com/cro...ad-progress-please-leave-im-updating-t2871269 but still not working. My carrier uses LTE Band 4.
I've also tried factory restores using the PC Suite. The original software is restored but 4G still does not work.
Any help would be appreciated!

Okp I let you know..the process es really easy...you spent more time documenting than doing it really...I think I'm going for a Cloud G3 Rom, which is more familiar and stable with the device.
