Question about LTE - LG Optimus G Pro

Dear Fellow of XDA
I have AT&T 980 and I successfully flashed stock back to stock (non root) using this thread http://forum.xda-developers.com/showthread.php?t=2302660
I first thing noticed was LTE did not appear. LTE was covered in my area. I went into apn changed apn setting no success.
I am confused but I did was right step from the link and did not get LTE. I checked the file and it what I needed for my device.
This not an urgent, but was very sad about it.
Thanks

Note 2 I317M AWS Issues

Hello everyone,
I picked up a 2nd hand white Note 2 I317M, Canadian variant, with the intent of using with Mobilicity, which uses AWS 1700 bands. So, after I got it, I applied this mod to enable AWS http://forum.xda-developers.com/showthread.php?t=2068041 . Unfortunately, even after flashing the QCN file, the phone did not detect Mobilicity. I rooted the phone and installed skynote 8 ROM then flashed the QCN file to unlock the AWS bands, it still didnt detect Mobilicity. I then followed this guide here http://forum.xda-developers.com/showthread.php?t=2026569 and installed a T-mobile ROM, then flashed the QCN file, and it still didnt detect Mobilicity. The only networks it shows are CDN ROAMING (aka Rogers), TELUS, and some other network I cant remember. I even downgraded to stock 4.1.1 and applied the QCN, with no luck. I have two friends who have Canadian i317M Note 2s, with the AWS QCN patch applied, and both of them are using them on Mobilicity and Wind with no issues whatsoever. Does anyone have any idea whats going on here? Please help
Thanks!
EDIT: Also want to mention that earlier today when I had Skynote running, the phone connected automatically to Mobilicity after leaving it by itself for a long while. However, it couldnt call or do anything, and signal strength was very bad. After I did a reboot, the phone wouldnt find Mobilicity anymore

I believe it does because the original aws thread is in general too
Wrong. You are troubleshooting and asking a question. Does not go in General. General is for sharing something useful and that is not what this thread is.

OK why are you bein the post vigilante? That thread got closed and I did not get my issue solved on the AWS thread. I'm pretty frustrated right now because there is no reason for my phone to be not working. So please, unless you're going to actually post something helpful, dont post at all. Thank you

I just followed the instructions on the other thread by flashing the att dumimei file using qpst. I tried almost everything possible (with the exception of manually changing the nv parameters) with no luck. So i just sold it and got a t889 aws model

I downgraded mine to 4.1.1, flashed it with the one you used (att dumimei ) and it worked!
Your post was the very first one that showed up on google when I searched I317M AWS. Luck you replied right away or I'll be reading and searching the whole night looking for the right one to use.

Hey slickflick, did you do anything else?
I downgraded to 4.1.1 as well and flashed it, and it still doesn't work for me.
I had the same problem as yours. I first downgraded to 4.1.1, flashed the qcn file and reboot, it didn't detect wind. I put back 4.1.2, flashed it again, it didn't detect. In the end I put it into recovery mode, did a reset and reboot, it detected wind. Then everything works!
After I have applied the the ATT_I317_AWSMOD_dumimei.qcn file (provided by sjravi) on my Rogers SGH-I317M, it's only able to connect to the Wind network only 1/10 of the time.
Under "About device->Status", it does appear to be connected to the "Wind Home" network but it fails to establish connection with the mobile network. In fact, when I try to search for network operators, it can't find anything.
I've tried setting the Service Mode to "Automatic" and "WCDMA ALL", but nothing works.
I own a rogers i317m note 2 have had it on rogers since January 2013..
Today I devided to unlock it! (After a years of *****ing about rogers):
-First I downgraded to version 4.1.1
-Then following the guide on this form to get into the menu with the *# what ever command. I unlocked the phone (make sure to wait the 30 seconds and 60 seconds they recommend after clicking the options) then tested it on a bell sim which worked.
-Then I updated back to 4.1.2
-Next I downloaded the qcn file thing off this site for att device changed the usb option in the hidden menu then backed my file up then restored the downloaded qcn as mine and rebooted put in a wind sim had to go under mobile networks let it search for about a minute and it worked.
Been on winds network for about 9hours now with no problems. Sorry for horrible grammar posted this of my phone.. but if anyone here is having issues with there rogers phone on aws network feel free to message me.

did u get it working?? i have the note 2 i317 originally from telus...got it unlocked and then used the forum's tmobile rom and patch the qcn and it worked. i can use it both on mobilicity and wind right now.... mobilicity however has poor reception. when i switched to wind , reception is strong and my battery lasted longer too.. dunno why... just make sure when u patch the qcn, make sure there are 2 ports which u apply one on. that's how i troubleshoot it and didnt need to install anything else
I followed the instructions on unlocking the AWS bands (did it to 2 buddies Note 2 phones, and worked without issue). However, my phone OCCASIONALLY will find Wind, and will only register on main roads.
I have an S4, and it works anywhere without issues (unlocked AWS bands also), but the Note 2 will not register except main roads, and even then has choppy service.
Used the AT&T qcn file that is found on this site. Not sure if there is something I am missing for the Note 2.
Looks like the same issue as nawkwan.

[GUIDE] How to enable LTE on the Mobilicity / Wind / Vidéotron T889V

Hello everyone,
If you're using an SGH-T889V (originally from Vidéotron, Wind or Mobilicity) on a carrier that runs LTE on the AWS band, e.g.: Rogers, Bell, Telus, Fido, Virgin Mobile Canada, Koodo, AT&T or T-Mobile; this will allow you to enable LTE.
Note: Vidéotron has launched their LTE network in September 2014. As of writing this, it is unclear whether there will be a new T889V modem released with LTE enabled in the coming weeks, much like there was with T-Mobile USA when they launched their LTE network.
If you're using a T-Mobile USA SGH-T889, this guide isn't for you.
The usual disclaimers apply.
Actually, let me rephrase that: This mod permanently damages your phone, and irrevocably voids your warranty.
No one has been able to flash back to a T889V modem (be it ALJ4, BMA3, CMK4 or DNE7) without encountering bootloops afterwards.
Interestingly, T889VVLUDNH2 did not bootloop, it simply showed an "unknown" IMEI and baseband with no network connection.
Some background:
A rather lengthy post explaining what I did and what happened
TL;DR version of same
Additional relevant threads:
Getting LTE to work on fido
Need Help Please WIND 889V Borked
You'll need:
LTE - Coverage, known working microSIM, proper plan and system provisioning, etc...
Proper APN settings for your carriers on hand. (Better yet if you're running TouchWiz ROMs: proper CSC files and knowledge on how to modify and apply those.)
ADB
Clockworkmod/TWRP recovery
CWM/TWRP flashable I317M modem image. (I originally used the BMA3 modem, although the mod should work with any of them.)
Bell/Rogers/Telus I317M modem files
I317MVLALJ2 4.1.1 initial release (This one could be of interest for unlock purposes...)
I317MVLBMA3 4.1.2
I317MVLUCMK5 4.3
I317MVLUDNF1 4.4.2
I317MVLUDNF3 4.4.2 (I haven't downloaded the full Odin image and prepared a zip for this one.)
I317MVLUDNH2 4.4.2
Mobilicity/Vidéotron/Wind T889V modem files.
T889VVLALJ4 4.1.1 initial release - CAUTION: flashing this on top of a working ALJ4 modem installation has been known to cause bootloops and NV item corruption.
T889VVLBMA3 4.1.2
T889VVLUCMK4 4.3
T889VVLUDNE7 4.4.2
T889VVLUDNH2 4.4.2
Once you've downloaded the above files:
Backup your NV settings (in CDMA Workshop text format) as per this thread. You can also use the EFS Professional Tool (currently at version 2.1.61) almost identically to the older NV_reader_writer tool. (It also contains the IMEI NV item generator functions that Peoplearmy's tool had, apparently gone missing too.)
The only things I'll add are that:
RMNET + DM + MODEM is not available, you'll have to use RNDIS + DM + MODEM instead.
Finding the COM port can be done in device manager, you may need to refresh devices or disconnect and reconnect the USB port. If it's been properly detected, you can also click the Port text to the left of the droplist, there's an autodetect function there.
Also use this guide to backup (in QPST/QXDM .qcn format): http://forum.xda-developers.com/showthread.php?t=1946915
Optional: Backup the raw mk9efs partitions too, as per @connexion2005's suggestion: http://forum.xda-developers.com/showthread.php?t=2079705 (they're not necessary for the mod itself, and are only made as an additional precaution)
Optional: Backup the raw mk9efs and efs partitions with this CWM or TWRP "flashable" zip based on the Synergyrom team's work. It outputs the dumps in a ready-to-flash restore zip.
Consider backing up other files and data from your phone with the usual complement of Titanium Backup, nandroid and so on. Copy those off the phone.
If you're running an AT&T or T-Mobile ROM: you may have to flash another ROM as well. The stock T889V ROM has a "Network Mode" setting that lets you toggle between LTE/WCDMA/GSM, WCDMA only and GSM only. The I317M and N7105 ROMs also have this, while the I317 and T889 probably don't.
On the T889V ROMs: to see LTE become an option, you'll need to edit your CSC files and remove the <CscFeature_Setting_DisableNetworkMode>lte</CscFeature_Setting_DisableNetworkMode> line in /system/csc/others.xml. This setting is only cosmetic: the notification bar icon will show "4G" and you won't see LTE in the network mode settings. However, the phone will still use LTE, which can be confirmed by looking in Settings / About Phone / Status. (I've come across this while flashing ROMs with unaltered CSC files.)
Let's proceed with the actual modification:
Reboot to recovery, flash the 317M BMA3 modem. Wipe /cache and Dalvik cache for good measure.
Reboot phone. No bootloops? Good.
Check in Settings / About Phone that you still have a valid IMEI. (It's possible you still do at this point.)
Reboot the phone. This time the IMEI and service should be lost.
Using the same procedure you did to back them up, restore your NV items.
Reboot the phone.
Confirm your IMEI is correct and that you have service.
Check in Settings: Wireless and networks -> More settings -> Mobile Networks -> Network Mode that LTE/WCDMA/GSM is selected. Another menu worth mentioning here is the "Band Selection" menu accessed through the *#2263# dialer code. Note that if you force the phone onto the LTE bands, you will only have data service, and no voice calls or SMS.

Those are very much a belt and suspenders bit. They're not to be restored in the instructions, and my inclusion here is mostly because connexion2005 had requested a set for a JTAG repair. I'm taking a guess here, but if there's any calibration data or other phone specific parameters in there, having those from your device on hand can't be bad.
What if I suffer boot loops, didn't do any backups, and my IMEI is already Zeroed out on my T889V? How can I fix this?
I have my IMEI still since it's written on the purchase box of the phone.
I used to be wind, now virgin mobile with LTE sim. I flashed tmobile modem. No love. Flashed T889V modem back, then got boot loops.
Please help!!!
edit:
Hi Darkshado, really hoping you can help.
I've done more reading. I can't seem to make the boot loops stop.
I've done odin to factory rom image. No luck.
I tried i317 custom modem you have here on XDA, no luck. Also Tmobile modem, etc... no luck.
I used CWM and permission fix, etc.. no luck.
My boot loop is a little weird. It will boot and stay live (working - no signal though) for about a min, then it will say some android.media.process is not responding and reboot.
So I can't get NV to inject my IMEI as it will reboot too soon. From what I read, NV needs 5-10 min??
basically, I did JEDIX-15 tmobile rom install with latest tmobile modem. That's how I got into this mess. I have a T889V and virgin LTE sim such as yourself.
I just can't seem to make the boot loops end so I can move forward....
Try writing flashing back the T889 baseband and restoring a T889 or T889V NV items backup.
http://www.mediafire.com/download/p5025pxtp9vgk4k/NV_items.7z
Will this do?
T889UVBMD1
from: http://forum.xda-developers.com/showthread.php?t=2102380
I'm going to try and odin the factory image and see if that stops the reboots.
I'm guessing baseband is the same as modem correct?
I'll go give it a try now and use CWM to inject it first before I odin.
I've never done an NV restore let alone backup, so that seems to be my hick up. I'll do some research and get that done then and get back to you.
Thanks for the assistance.
edit:
I'll try to write NV, but that might be an issue since I need the phone not to reboot, and it does in under a minute usually.
Any suggestions, or specific rom I can try to write so I can eliminate the reboots so I can do the nv?
edit2:
ok, the tmo modem from that link above worked. It's not boot looping after a min now!
There is still zero signal. Does not connect. When I do *#2263# and choose automatic, it says menu does not exist, etc...
going to to try inject my IMEI with NV.
Will report back.
Edit 3
Ok, just used nv read/write to inject your t889v nv file. Then generated my imei and injected that.
reboot, and got signal! yay.
thank you so much!\
When I go to settings. I only see WCDMA/GSM/AUTO. No LTE option. I think I read somewhere that is cosmetic?
If I NV write the T889 NV file from deeznutz1977 will that fix it cosmetically?
Thanks again!

20% More Awsomeness
I switched over to Telus sine Mobilicity is going under . I could only get HSPA+ @ 5Mbps, Now I too have fully working LTE. Albeit with weaker signal strenth due to higher band freqency. But I can just toogle LTE when needed. I must admit that second reboot with IMIE 0 and no service was a bit nerve racking, but the backup was flawless. Thanks a million OP. ^_^
i edited the csc called other....
and the LTE line was already not present.
The LTE option is still not in the mobile settings however.
When I do the *#2263# menu and set it to LTE the data does keep working. And I do see it in the system info. Also using a tmobile radio with the JEDI-X15 rom. yay.
But I'd like to solve the cosmetics side of it.
I did inject the t889V nv setting.... could that affect it? Would the t889 NV settings fix it?
edit:
still no luck getting LTE option to appear, although it works, I'd like to solve the cosmetic side of it.
Any help?
You can also get confirmation that LTE is active by checking in About phone / Status.
I don't feel like going through the 664 pages of the Jedi X ROM thread to see if they've altered the network icons or not. Being based on the N7105 ROMs icons with either "4G" or "LTE" captions should be present. Are you editing the active CSC files? Namely those in /system/csc/ ?
I should mention that some CSC edits only apply upon factory reset, e.g. activating WB-AMR, (a.k.a. HD Voice). One neat trick is to make a backup in recovery (nandroid or TWRP), factory reset, then reboot to recovery and restore the backup. I don't recall if this applies to the network icon related lines or not.
Older Modems
Question?
As I stated before it was a smooth transition. But... Some claim the older modem worked better (I317M-I317MVLALJ2). I tried through TWRP as before but the return status says FAILED. No changers are thus made. Any ideas? Thanks.
I've been able to flash back and forth between ALJ2 and BMA3. You're saying the linked ALJ2 zip refuses to flash? I'll have to check, but this might take a few days as I'm:
-rather busy IRL
-stuck using my old laptop (mushy, thoroughly worn out keyboard with an overzealous enter key that fires the moment you hint at touching it and a dead left shift key) while the other is in warranty repair (failing PSU seems to have damaged the motherboard and/or dGPU)

yep, I edited those CSC files as per your original write up.
I did not factory reset. And yes, you are right. A good example is the Nexus 4. It needs a factory reset to keep the LTE settings ( unless you go to the "INFO" menu, and then you need to reset again.
Okay, I'll try the reset tonight. See what happens. And yes, I see LTE in system info.
Also, when I use speedtest, it records it as lte.
Honestly, I'm just happy it works again...

Problem Solved. The issue was I am using SDCard encryption. For some reason TWRP can SEE the cards files, but not use them. When I moved the modem to internal it installed fine. Sorry bout that.

It should. My data in this department is very limited, since I don't have an active Videotron account on hand. With that said, I got a working speed test on Videotron's AWS HSPA shortly after sorting my phone out this winter. (I simply dropped by one of their stores while at a shopping mall and nicely asked a sales rep to borrow an active SIM card. Showed her the menu unlock method as a thank you.)
I also got to use the phone with T-Mobile USA earlier this year, getting both HSPA (some of it likely AWS, though I didn't get the time to check) and LTE.
@Darkshado thank you very much for the T889VVLUDNE7 modem. I just flash the zip in cwm and it work perfect for my Videotron T889V.
Thanks for putting this together!!
Quick question - I have a t889v from Wind Mobile. I switched carriers to Rogers, and in the process screwed up my phone and had no IMEI/Baseband. Had to send it in for repair to replace the board. It came back with the baseband T889UVUCMK7.
Do you think I can still use this method? I'm currently running a T-mobile Touchwiz 4.4.2 ROM (Test Rom v1.2).
What does download mode give as product ID? You may well have a U.S. board in there now.
The later T-Mobile T889 basebands support LTE out of the box. Make sure your APN settings, plan and SIM card are correct, and that the modem you have does support LTE; if not, you might just need to update that.
I know some people here followed essentially the steps I did, but with the T889 modem instead, but I don't think it applies here.
Good luck,

Trouble Reconnecting! (Modem T889 on T889v phone)

Hey so im afraid im on the same boat as those who flashed a t889 modem on a t899v version of the note 2. I had fixed my signal and etc so now I have a working phone which although was a pain im glad I have a working phone. But for some reason whenever it looses connection to WIND HOME, it can never connect back to it untill I reboot the phone. ALSO when I try going automatically to search for a connection it either looks forever until a force stop or nothing happenings if I do manual it shows wind home and like 6 versions of WIND AWAY, no matter what I touch it will never register it even though it claims it is trying to.
Any help would be greatly appreciated. If it helps even though its the same error throughout what ever rom I use im using a t889 modem,with tweaked 2.5

You can brick your phone if you use a modem not intended for your phone. Just flash the T889v again.

Also, once the T889 modem is flashed on T889V phone, does that unlock all the available LTE bands? For instance, would I be able to use the AT&T, Rogers, Telus/Bell LTE bands? Or would I need to flash specific modems for those phones?
Is there a custom modem file that would enable all the LTE bands the phone is capable off?
Are there any disadvantages to installing T889 modem on T889V? Would I lose anything?

[Q] Note 2 does not work ATT To T-mobile, wife's iPhone 5 works fine

Hi,
I have note 2 from AT&T at 4.1.1 with I317UCALJ2 and I took t-mobile connection, I can not have mobile hotspot on. Also I get call drops and less 4G connection as compared with my wife's iPhone 5, she is having consistant 4G and mobile hotspot. I called t-mobile they changed my APN settings to fast-t-mobile.com, but it did not work much, then I was reading a forum and I dialed *#2263# and selected WCDMA ALL (when I did that my APN in the settings changed back to epc.tmobile.com). Now I am getting 4G band but still no mobile hotspot.
My phone is unlocked, I unlocked my phone using the key combinations posted in this forum last year. What should I do to make my phone more usable?
Thanks
sounds like some software problems try more roms..

I am not rooted and I have the stock ROM. Can someone please guide through the process?
Don't check CDMA all. Check LTE and then make sure you use the fast.tmobile.com SONg setting

I tried, still no luck

I tried that, still no luck, should I put any custom ROM? if yes then which one?
No rom yet....
Since you are changing carriers entirely...have you cleaned the device to make sure no bad data is present ??
I would suggest doing a factory reset to clean the device....
Then enter in the T-Mobile APN again and test...
If the process does not help ...a new or different modem may be needed to improve your signal...
All of the steps to do this are in the general and development sections...and you should begin by searching and reading the steps....
Go slowly...until you understand the process...and only then should you attempt any flashing....
We will be here to help....but you need to learn the process if you intend to flash files to this device...
Start in the "everything" thread in the general section....
It covers the basics of root and flash procedure...and how to avoid mistakes that catch several people...
And do not update your device via OTA...
It will give you a Knox bootloader...and that is not good for users...especially new users to flashing...
Read much....learn much...and only then should you flash....g

are you seeing LTE signal? if not, then you are on T mobile's legacy 3g or possibly the reformed 1900 hspa. Since the phone will not get 42mbps hspa, your speed maybe a bit lower due to 21mbps hspa. I am using the phone on t mobile network and do not have issue. i did have the latest att modem. When I was on the 4.1 rome, I did flashed the latest modem before the 4.3 rome.

I unlocked the phone, I also have supersu and triangle away on my phone. I do not remember what all I did. But I am on 4.1.1. If I do a factory reset, will I loose everything meaning unlock etc? Or should I install a modem? If yes then which one?
If you are ready for the 40 mbps hack....here ya go...
If you have a PC and a few minutes....this link will get you on track ...
I use ATT and have never used this method...but many have...and report proper speeds after unlock to TMO...
Good luck...g

factory reset should not change your unlock. The phone should stay as SIM unlocked (if that is what you meant). Once it is sim unlocked, it will stay as unlocked. It should not affect your root either as factory reset (though I am not 100% sure since I have custom rom so cannot remember if stock rom will remove root). Often it is best to stay with the same modem as the rom version. Here is the link to the modem list: http://forum.xda-developers.com/showthread.php?t=1987541
I have the latest one but I am using 4.3 rom. I cannot recall which modem I had when I had 4.1.2 rom so do a bit search, but I think it is the MJ4.

[Q] 4G Lost After Flashing Firmware

Hi everybody,
I'm totally new in this flashing world and I was messing around with my new Xperia Z1 Compact trying to get Kit Kat installed because when I bought the phone it came with JB 4.3. I flashed Latest KitKat Nordic 14.3.A.0.757 unbranded, and everything worked like a charm until I discovered that I lost 4G connection (It only connects to 3G). I went to settings to select network, and LTE is checked.
I was reading about this matter and it seems that nordic ROM doesn't support LTE Band 7 (2600Mhz) which is the band in my carrier. I tried flashing Central Europe Rom and Global rom for journalists found here in the forums. None of them seems to support my LTE band. I want to know if there is any way to recover 4G changing any setting or if you know a link to any generic ROM compatible with LTE Band 7 (2600Mhz), or if there is any way to revert to my original Jellybean 4.3 ROM using PC Companion or Sony Update Service. Any help will be very apreciated.
Hello,
I am using the Generic UK .757 on a BAND4 LTE network in Canada.
you have checked off the first thing to do from the checklist..
second is to make sure your APN settings are correct.
All these are simple, but if still no luck, some labour is in order.
Need to do full wipe and clean re-install
IF you are not rooted, just launch Sony PC companion with the phone NOT CONNECTED and do a repair. It should by default take you to KK
At the time of flashing, You probably had the wrong boxes checked and unchecked in the WIPE and Exclude boxes..
I'll try the two options
Thanks guys for the responses.
First I'll try to flask UK ROM to see if finally I get kitkat working on my phone. If this doesn't work I'll take the second option with PC Companion to restore the original ROM. I'll post the results.
It seems this rom doesn't work for me

Hi Phil,
I found UK rom in this forum ver. .681 and flashed it, then I downloaded OTA update to .757. So far the problem remains. I discovered that I was wrong about My LTE Band, is 7 not 4. Apparently there's a carrier in UK with band [email protected] same as here (Colombia), so theorically this rom should work, but this is not the case. I'm trying to change more settings without luck. If you know something to help me, it would be very appreciated. Thanks.

Hi jewelkobayashi,
I tried the method you wrote, but, despite the phone being disconnected, it downloaded the same ROM that I recently have flashed (GLOBAL .757 commercial and Journalist). Is there any other way to download the original Phone ROM . I know my original ROM is GLOBAL-14.2.A.1.114 and the customization number is 1281-3723. I haven't found any site to download this exact firmware. If you know something, it would be very appreciated. Thanks in advance.
Are you sure about your customization number? Because it gets changed if you flash another firmware. Here's everything you need to know: http://forum.xda-developers.com/showthread.php?p=52011642 to download your firmware. By the way, what's your country, branding and SI-Number (so I can add your customization number to the list)?

Stop flashing random ROMs and check your settings! Unless you have a different model phone than the rest of us (there are three, D5503, M51w and SO-02F), then ANY Z1C (D5503) ROM will work, but they come with different APN lists as bundling every carrier in the worlds APN settings would be a waste of space. Go to Settings > Mobile Networks > Access Point Names, and edit or create the correct APN in there. Look at a friends phone or on your carriers website for the correct settings. This is your problem, no doubt about it.
Please note that some carriers (mine included) have a special APN for LTE. E.g. standard is internet.tele2.se, LTE is 4g.tele2.se on my carrier.
...I have no idea where you're getting your data from, because literally every LTE network in the Nordics uses band 7.
Finally it worked

Thanks for your response. I verified APN settings with friend's phones and it was identical. Finally I called my carrier's help desk and after some try/error setups with them, they gave me an alternate APN that worked until I came home where 4G icon dissapeared again. Then, I was surprised with helpdesk response when I called them again. "There is no 4G coverage in your home area". O.O What is intriging to me is that the phone displayed 4G all the time when I just bought it (Even with restarts and wherever i was) and this changed only when I flashed a generic rom. Is just a silly assumption, but, is possible that carriers can make things like force 4G icon in their custom roms to make advertising or something like that? Just asking. Anyway, Thanks a lot for the responses.

Emmm do you have a manual to how to use the ussd??
I went into it to check it out, I touched I don't know what...
And now I can no longer connect to my network provider...
(reboot doens't helps, changing to wdmca or gsm or other options doesn't changes, VPN seems ok, I have no signal... )
Help!!!
Ok, this is what I did to screw it all
Go to the ussd *#*#4643#*#*
Go to phone info
Go to setings and Select radio band
It gives me the option of GSM/UMTS band = USA Band
-> I no longer have WCDMA or GSM connection :S
(LTE still works...)
Now, how do I go back to my previous options? or does it has nothing to do with it, and the problem is something else?
EDIT> problem solved, I had to reflash my ftf by just updating the FOTA (not sure I needed this...) and the BASEBAND... Now I am back up and running again.. >D

Good to know that your problem is solved, even better you solved it yourself. Sorry for not being able to help, I don't know about that ussd code I shall try.

Actually, there's an app in Google Play that is a shortcut to this ussd code : 4G LTE SWITCH
