Hello,
I have a problem with my new HTC One bought on a chinese website.
I discovered (unfortunately after the phone arrived), that it is Sprint Developer version and I tried from some days but I can't get 4G LTE networks.
It works with my italian sim card only in GSM/UMTS and I think that 4G networks is only possible with USA sim card, or however with CDMA sim.
How can I fix the problem?
I have tried to flash any kernel for the original HTC and flashed some custom ROMs, but in any case I can't access to 4g networks!
Are there any firmware (I don't know if it's radio or kernel but I need the firmware that enable 4g) that can I flash without bricked the phone?
I have already read other old posts in this forum, but nobody gave the solution.
I have read that the internal phone components are the same, too.
Thanks
N.B.: In my simcard 4G is allowed.
Nobody answer?

Dear Modders I know this is only HTC braned phones forum but please don't delete my post because this is not brand problem but common unlocking maybe somebody can help me here ...
After long time tests I came to on result.
My phones wi-fi not working becuse it's unlocked ant then I insert another sim card which is not working in my country and there is not GSM antena indicator on that time wi-fi starts working but then I put my normal sim card which is working in my country and phone getting signal from GSM network it blocks wi-fi and I can't use my wi-fi even after that when I insert back the other cart which don't have network coverege in my country again it's not working till I fully format phone from settings.
Please if someone can have solution with this post here or tell me how to fix this so have working phone wit wi-fi and gsm network togheter
is your phone rooted?
Rooted or not, try a Factory Reset. That might fix your problem. If its rooted, flash the rom again after doing a full wipe.
Dear nephron phone is rooted I tryed reflash rom many times and no success even after full wipe. I think my problem is that my phone unlocked with the code I get from T-mobile and when my phone uses GSM sim card and I am getting registred in gsm network wi-fi can't find any network but when I put other sim card which can't register in my country because of there is no network for that sim card that time wi-fi works perfect.
So by my understanding GSM signal is not letting wi-fi to work how to do that to get working togheter ?? and also I have some doubt about unlock code can t-mobile have to unlock codes for on IMEI one will unlock carreir and another will unlock all functions? or I am wrong?
Please is there any expert on this issue so can help me with this...
Here is the my boot.img file maybe this will help to fix my wi-fi problem. please some adnroid developers maybe can give a hint or help me to fix my problem..

I am having the same exact problem with motorola Cliq and don't know what to do. Have you come to a conclusion on what to do?
The routine of the error is exactly what happened to you.
I seem to have an issue with the samsung captivate here in china.
I have a pilotx custom ROM installed, firmware 2.3.4 baseband version I9000XXJVT and samaphore kernel for the captivate.
this works very well in Israel, getting perfect reception and voice quality everywhere. however when i arrived in china i found out that my phone doesn't manage to connect to china mobile network (chinese SIM card is china mobile).
searching for networks i can see chn-cugsm, which is a china unicom network. if i put my SIM card i can sometime connect to the network as a roaming user but my battery only lasts for a few hours, seems like the phone is constantly busy trying to find a network.
when i try to install another modem using CWM it looks like its going well but when i reboot the phone baseband version remains the same XXJVT, i tried both i897 and i9000 modems but can't seem to change my modem, is it possible that the modem is installed but the version is displayed incorrectly?
second thing is - is anyone using china unicom and can tell me which modem works best for them? their website states their network is GSM 900/1800. the israeli provider is said to be using GSM 1800
Try using ODIN or Heimdall to flash the modem? Can't help on wich modem.
isnt the VS980 supposed to be unlocked for GSM use ?
I am in India at the moment...i have 3 Verizon G2 phones...SIM cards work fine on 2 of them...On the third one...it does not detect the mobile network...sim is detected ,coz it gives no alert...and when i search for networks...the networks are shown...it just doesnt connect to the network...the sim cards work fine in other phones...in the other G2 phones and in a HTC DROID DNA...so its not the sim at fault....
Have tried multiple SIM cards from Vodafone/Loop Mobile/Airtel...none of them work on this particular phone..
When i search for networks...im getting networks...but cant connect to them...most times it shows error while searching for network...
What can be the problem ?
Please help me out...otherwise will have to send the phone all the way back to USA...
if i am right... verizon phone is unlocked to all US carriers only....try to verify if its globally unlocked
EDGE/GSM (850/900/1800/1900), HSPA/UMTS (850/900/1900/2100)*
those are the frequence bands it support.
India support 900 1800
So technically it should work..
try *#06# to check if it shows imei number and other is to try to unlock phone

I got 3 Verizon g2... 2 of them work fine with Indian sim cards.
The third one is facing this problem.. I thought the IMEI was lost.. But IMEI is still intact and dame as that on the box.. Also Verizon g2 has no unlocking system as it is already unlocked..
That ink which u posted says it is unlocked for us carriers.. And not that it cannot be used outside the US.. People use it in UK, Australia.. Mexico.. Germany.. To name a few..
It seems the efs partition is corrupt but I don't know how to fix that as I have no backup..
Also if it wasent unlocked the sim won't be detected.
When I search for networks, the networks show.. It just doesn't connect..
The problem exists only in one of the 3 phones..
Ok then install custom rom and try with that.
I can recommend you for cloudy g3 rom. Best one out there
If your phone is not rooted and no custom recovery then open towelroot.com from your phone and install apk and it will root right a way
Then install rashr flash tool from play Market and install twrp recovery.
It's the easiest methods to install custom recovery and root I can recommend.
I hope this will work for you and don't forget to setup apn setting if data plan not working

I have a very similar problem. Using a SIM with 850 mhz HDSPA provider LG G2 works.
But when I use a SIM at 900 mhz, I got only voice. No 2G even.
Ideas?

Fixed for me. I rooted the phone. I installed the cloudy rom, based in the D802 version of LG G2, now, the phone works perfect. No issues at all.
I suggest change the rom and try other software.

does the phone have a big verizon logo in the back or in the screen? Then yes, it's a VS980. Pick that option in the aroma installer.

VS980 not picking LTE Frequency
I am from Pakistan and I have the same issue. Did anyone find any solution?
Ihave thisproblem too
I am using Verizon G2 32gb.. and yes... signal reception is so so soo poor.. at same locaiton, others handsets with same network are receiving very good signals while its on no network :/
Not picking any frequency or signal at all
Upgraded my VS980 to lolipop and after a couple of days same thing happened to me. I am in Pakistan btw. Sim is working fine on any other mobile. Have tried restoring to stock nothing happened. One thing i want to add is when i change my location sometimes for a couple of minutes, network do appear. But it does not makes call or uses data then it again gets to emergency calls only status... Phone is no better then i web browser now.... Help needed
Also not connecting (But it detects networks)
I have an lg vs980 and I was using it with H2O wireless and later I changed to Simple Mobile. I'm living in Puerto Rico. The phone was working all right and, suddenly, one day it was always displaying 'emergency calls only'.
I did factory reset, then I reflashed stock lollipop and it was like nothing happened, keeps displaying 'emergency calls only'.
Then I found this post http://forum.xda-developers.com/showthread.php?t=2394689 and applied the patch but didn't seem to resolve the problem.
As a last resort I tried flashing cm 12.1 and before first boot applied the patch from the cited thread but no result, keeps displaying 'emergency calls only'.
Has anyone found a solution to this problem?

as far as i know the bands are hardwared. You cant change them with program. No idea why 3g wont work. Try installing stock rom and then test it. Dont think kernel has anything to do with it, kernel is conencted to cpu. As i said ,try stock rom with odin, that usualy works. Then install cm again.
4G issue

You might need to go to samsung repair centre and check it out. I had a prepaid sim card and the carrier with who i was with back then they only had 3G. Until I change carrier who had 4G service I was still getting 3G. After calling support here and their, got my phone checked and it was a hardware problem, lucky it was still under the 2year warranty. I contacted samsung and handed over my phone the repair centre and finally my 4G had worked.

Hello peoples,
Buying a P7-L00 can be interesting from China, with the dual Sim slots, but you have to know that the 4G will may be not work.
For exemple, i live in France and the only operator which is compatible with the L00 chinese 4g chipset is Bouygues. (All other ORANGE/SFR/FREE will be 3G) This is due to frequency use in their 4G networks, the P7-L00 support 3 out of the 4 channels frequency but all those operator only support the missing one.
So no 4G for this little phone, if not a Bouygues client.
Another thing: roms.
I installed TWRP and unrooted the device. Since then all official update are failing.
When i boot in twrp, and choose the update.zip file, it says that it is unable to check the zip file....
So im stuck with previous version, unable to install mui3.0.
So if people have a solution on how can i upgrade my device, would be nice.
Regards

Flash stock recovery, put update on sd card, and make force update.
