i have htc m8 harman kardon edition model number 831 c. It doesn't support lte band of Pakistan due to frequency unmatched. to unlock all the frequency of lte band i read some threads in this website and change the nv value of mobile through QXDM and QPST. unfortunately, due to some mistake or by wrong information i have changed the nv values of gsm as well like 0441 etc. i don't know the exact values now, but after this my phone is not picking the signal. it shows circle on signal bar and continues. Aeroplane mode very difficultly switch to on otherwise signal bars remain fluctuating and drain the battery very quickly. i am not able to change network mode by applying *#*#4636#*#*. i have flashed the phone, install custom rom, reinstall software, root the phone but no effect.
Kindly help me i dont want to lose this phone.
waiting for your reply.

Hi All,
I am starting a new thread for India specific networks on the Bionic.
I am new to this so please don't mind if i write anything stupid which i may haven't understood yet.
I got my Droid Bionic running on Stock ICS from States to India and inserted a couple of GSM sims which worked fine for a while without any tweaks. I used my device for one whole day(made calls didn't test data) and when in the morning i woke up there was no network. At that time in *#*#info#*#* it was showing as detecting network but as soon as the location updated, GSM would show out of service.
What i have done so far:
1. I flashed Eclipse ICS v 1.2 ROM and got network though very weak but couldn't make no calls.
2. I got ICARUS HD - 1.6.1 and applied the tweaks as mentioned in phone and got network stength increased but still no calls but a strange thing happened when i tweaked with build prop editor running ICARUS HD, when i changed to WCDMA Preferred and turned radio off and on it registered on the network gave full strength and GSM: showed in service as well, though this was only for 10-15 seconds and i couldn't test call.
3. Now I'm running CM 10 - released on Jan 18th and to my amaze I can use 2G Data though GSM state is Emergency Calls Only.
Following might be helpful to understand:
Current Network: TATA DOCOMO
Signal Strength: -99 dBm 5 asu
Neighboring CID: Unknown
Cellinfo: Blank
Roaming: Not Roaming
GSM Service: Emergency Calls Only
GPRS Service: Connected
Network type: EDGE(Also shows EDGE2 at times)
Message Waiting: False
Call redirect: false
Call Status: Idle
Preferred network type:
WCDMA preferred
I have changed to gsm only, gsm auto and all others applicable to no help.
I am trying to run my phone in India on network: Tata Docomo which probably operates on 1800 or it could be 1900 on 3G.
One thing which i am sure of now is that this phone certainly has all GSM capabilities and its some tweak which is required which i cant figure out. I have personally seen my phone making calls and now its running data as well.
Please help me on this!
Seems like settings changed with build prop to run on T-Mobile or AT&T dont seem to work for networks in India. Tmobile operates on 1900 and Tata Docomo on 1800
One thing which wont let me sleep is that why did it run perfectly at first and why did it fail if i did nothing to it. Can the network block the IMEI or something of that sort happened. It's been two sleepless nights for me now, now praying to the Radio God!! LOL!
Did you manage to get it to work? You might be right in thinking that it might be related to IMEI. Did you try and find out if the IMEI is considered valid by your operator since this is not a true worldphone its IMEI might not be in their database?

Didn't work. I had to give up on it. There was actually no way in which i could get it checked with the network.
I sold it off on Craigslist last July!
I now have bought another one to test. Waiting to get back to India to test it again.
Not all bionic works with gsm, only wcdma. It's HW A after 36/11 and HW B

It's quite interesting that it did work perfectly initially and then with CM10, the data worked. Did CM10 rom include its own radio as well?
I found something interesting in this thread (not related to Bionic):
http://forum.xda-developers.com/showthread.php?t=945312
Good luck with your new Bionic! Does it work okay with GSM carriers in the US?
I finally got to try it and unfortunately it didn't work for me. Mine is HW A '12 Bionic and I am on ICS. If I go outside my house and search for networks, I get to see only one network(not mine). I see extremely weak signal in the phone info screen and also it shows gsm out of service. I tried 3 sims from different operators. Inside my house, nothing ever shows up. In other phones, I get to see many operators. Seems like it's definitely a signal strength issue if the gsm 900/1800mhz and wcdma 2100mhz bands are not locked. I'm not sure at this point what is the real cause. I even tried flashing just the radios from GB versions as complete downgrading is supposed to brick the device. Needless to say it didn't help. I'm still investigating and experimenting.

Hi,
I have now tried everything possible with the Bionic to run it on GSM network in India but it has failed to respond. I tried both hardware versions and can confirm that it is not registered as a world phone like most of new Verizon devices.
The worst thing which still bothers me is how and why did it work once(Yes, I made and receive calls on Docomo network in India). It will still show network strength , detect network but not register. I cant find no answers to it and have given up on this. The model is now obsolete and is clearly not a world phone in my dictionary but I won't deny it having GSM capability having seen it work personally. I have finally dumped the other bionic as well.
Good luck with your experimentation though!
My phone will not use 4G (HSPA+ or 3G) at my work indoors and favours 2G. My HTC Sensation could be made to use 3G by cycling the radio off/on - but this HTC One is not able to get any 3G plus. I assume this is not a ROM issue as it behaved exactly the same on the original US T-mobile ROM build. Just outside the building (and always at home) I get 4G (not LTE but T-mobile HSPA) speeds (slow here at around 4-6Mbps).
I know that settings can be changed to make the radio favour 3g/4G etc (even if a poor signal) but can anyone help here. I can sit the HTC One right next to the Sensation and the Sensation will show 3G with 1-2 bars and the One will show 4-5 bars with 2G! (and very poor data rates on the HTC One as you'd expect).
I am on a US T-Mobile model on 10.1 ROM with new radio (4A.16.3250.24_10.38.1150.03.zip) - VERY impressed.

Hey Mate,
I was also facing same kind of wiered issue, I am on Developer edition and In India and initially Was not not able to connect to any 2G network. I tried everything from Custom ROM to STOCK ROM, Radio, SIM card change, orperator change etc.... but mothing worked. I was only able to connect to 3G networks.
Today finally I S-OFF'ed my ONE and after that it's connecting to 2G and 3G both networks. I think there is something related with security.
Try to S-OFF !!

Thanks - but I can get 3G and 2G signals now. It is just that the phone seems to significantly favour the stronger 2G (more stable) connection even though a low signal strength 3G connection can be achieved (as shown on my Sensation). I do not want to try S-off just yet as that should really only allow the changing of H-boot and radio firmware etc. I have never read anything that indicates that S-Off can improve a given (un-changed) radio. It is this method I want to try first - I am already on the .24 radio but that made no changes.
I do know that it is possible to access a hidden (HTC Engineer?) radio menu by typing a series of numbers and hash (#) symbols into the phone dialler - that reveals a menu in which (I believe) you can change the priority of network selection.
It could, of course, just be that the HTC sensation radio hardware is better than the HTC One - I hope not.

Hey All,
I searched the web on and on and cant figure it out.
My provider Vodafone in holland provides me with 4G.
On some sites i read there is a minor update which activates the LTE option.

I can't really help you but as far as I know LTE is already unlocked and working on all international S4 Actives. Mine certainly worked perfectly out of the box - although I turned it off promptly because I have ****ty 4G coverage where I live so it was nothing but a battery drain for me.
Are you sure you have a 4G sim card, and that you are in an area where 4G has coverage?
If you go in under settings > connections > more networks > mobile networks > network mode don't you have the LTE option at the top?

Im not 100% but i got the textmessage from my provider, so i recon they only send it to people who are able to use the 4G.
Yes, i am in a 4g coverage area
i dont have the LTE option at the top no. i have:
- wcdma/gsm
- only wcdma
- only gsm

Well then I really have no idea - the only thing I can think of is that you might need to replace your sim card if your provider didn't already do so in advance of the 4G rollout. Hopefully someone with more information might step in here, but the international version is LTE capable out of the box. If you don't hear anything else I'd suggest to try and contact vodafone and get a clear answer from them first.
If you check the mobile networks in your area and don't see anything that supports LTE, you may just live in an area that doesn't have it yet (people get 4G and LTE somewhat mixed up - 4G is the overall identifier for a whole class of technologies with "4th generation cellular networks" basically while LTE is technically one of those technologies so, it should rightfully be classified as 4G in most respects.
Having said that, the only way I got my GS4A to function in LTE mode - meaning it actually shows LTE in the notification bar under the 4 with a small G and LTE underneath it - was to go into the service menu (*#*#4636#*#*) and change the preferred network type to either LTE only or LTE/GSM auto (PRL). Once I did that the radio would reset and connect and then it would be in proper LTE mode. Doing a speedtest with the Speedtest.net app shows LTE as the connection whereas with my standard setting which is WCDMA Preferred (T-Mobile AWS) it'll just show as "4G."
I've had no luck making alterations in the Settings/Mobile Networks section, I have to change it in the service menu to get LTE functional. I don't use it because here in Vegas where I live (specifically my home location) the LTE mode gets me about 1-2 bars of signal (about 8-12Mbps) whereas the WCDMA Preferred setting pulls in 5 bars rock solid and 25-35Mbps.
Can't do screenshots or I'd add them, I'm running the pre-release MI2 ROM presently and that aspect is borked.

I can check my area on the vodafone site. I live in a 4G network area 100%!
i guess my wcdma is sufficient then.. didnt experience speedboost tho..

That would be because you're on the i537 from ATT, rather than the i9295 that this discussion is about. I checked google and vodafone holland does indeed use LTE on the right bands in its brand new rollout, so it isn't that - most likely it's his sim that needs replacing or it's just not activated on his account yet.
hello
I have HTC M7_UL model, and trying to connect to LTE network with no luck, is there a way to check or diagnose LTE modem in the phone itself?
LTE discovery app shows 'one bar' on range permanently and no additional information regarding signal, *#*#4636#*#* and switching to LTE also fails
Thanks
-----EDIT---
Case solved, device do not support frequencies served by my operator, it is Sprint version and I need europe freqs, anyobody know if it is possible to turn on all the LTE frequencies in HTC m7 ?? I tried NV but values aren't writable ????
cheers

Hi everybody! I have a problem, my 626 Sprint just get 2G signal only,even though i already chosen 3G only in Network mode,
anybody help me to know what to do? thanks before
Same problem. Help pls
I'm having this same issue as I'm stuck on 2G while d device has 4G. Tried unlocking the bands through qpst and dfs CDMA tool, yet no success. From what I've read, we may b able to add bands with a custom kernel which I'm not sure has been created for this device.
Unactivated
I'm trying to activate my service with a CDMA carrier that is called choice wireless I haven't active the phone yet unsure if it will cause a problem no bars. Just locks the 4g LTE gsm. The carrier don't use Sims and I haven't yet to call them. Plz help
