new to this - THINK I've done the research and got it? - Mogul, XV6800 ROM Development

Hello, this is my first post her and my first experience in doing this.
I bought a 6800 off of eBay, It is the CDMA version w/ GPS, a Bell Mobility phone. I was under the impression that MTS (Manitoba Telecom Services) was still aligned with Bell, but it turns out that hasn't been the case in over 6 months, so now I may as well try and hack my phone. They don't use the same data lines anymore either.
I took it to MTS to get it activated. The calling and text messaging works just fine, but the data part does not work AT ALL. It gives me an error message "Can't connect for an unknown reason. To check your connection settings and change them if needed, tap Settings. If the problem continues, reset your mobile device according to your manufacturer's documentation and try again."
I've been doing some reading on the wiki and other posts here, and it's a lot to absorb for someone who is completely new to this. I THINK all I have to do at this point is unlock the phone, change the carrier to MTS, and enter the akey (which I could possibly get from MTS).
Does this sound about right? I realize I could put a custom ROM on and a new Radio ROM, but if I don't need them just yet I would rather see if this will work.

i feel a custom rom is the first thing to do to these phones.... sorry cant help with the other questions......

Can you call them and find out how their data connections work?
Like with me, for Sprint, I have to dial #777. You might just have to edit your connection settings

Can't speak directly to MTS, but on VZW, what I do is an esn change off the phone to my backup...flash the custom rom, then esn change back. This takes care of akey and provisioning.

Can't make phone calls

This is happening randomly I can't make phone calls. Most of the time I can't make any calls or receive any, I cleared the storage and looked up problems about this but couldn't find any(other than doing a full flash which is something I wouldn't want to do)
I was making phone calls last night and it didn't work for a while and then kaboom! It started working again but after a while I couldn't make any calls at all.
I got this phone yesterday its the t-mobile version and its unlocked I live in ireland and my network is 02.
My two questions are:
Why is this happening? And how can I fix this?
If I switch to android would I be able to make phone calls in this situation?
Please help!
Hmm, well it shouldnt make a difference, but try installing the cab i posted in THIS thread, post 4(which will have the added benefit of auto setting up your data connection settings too)
I'd also get rid of the stock rom too, though again, theres no reason it shoudl affect calls.
EDIT - oh hang on, when you say the t mobile version, do you mean the uk t mobile version (which is teh same as all other hd2s)? or the US t mobile version (which is a different phone in certain respects)

I have the US version with the upgraded ram.
oh ok, (though they all have the same ram, it just needs unlocking on the regular hd2, its the rom that you have double of.)
give that connection cab i linked to a try, just so you can rule it out. also, i know you said you don't want to flash a new rom, but it will sure get rid of the useless stock tmo apps.
I tried the .cab file and I still can't make phone calls. It still only works randomly and I can send messages but I can't recieve any.
Hmm, the phone is unlocked to the network you wanna use, right? and it supports the right GSM bands? (Im sure ot probably does)
all i can suggest is open teh phone screen, hit menu, options, menu - advanced network - and try disabling HSDPA/HSUPA
also on phone screen - menu - options - scroll down to band - and try messing with the settings in there (GSM wcdma, and teh band frequency options)
i've got the same problem.
Did you solve it?

Connected to carrier but signal says Roaming, no APN settings, but have internet

OK guys the title explains my predicament. I live in Costa Rica and am currently with the I.C.E for any of you that may be from here. I purchased a used S2 from a guy that bought it from Claro. So the first thing I did was get rid of the stock and I flashed everything like I wanted which is:
CheckROM v6
Using DarkKnight's Kernel
I'm using the KI3 radio but I have about 20 others and none of them changes my situation (coming up)
Original info was:
PDA-KG7
Phone- KG4
CSC - KH2
NOW here's the deal, my network icon has full bars but with an R for roaming. The phone works fine, I somewhat have data connectivity although SLOW, BUT when I go to APN settings there is nothing there NOR will it let me save a new APN, BUT I do get the 3G and H icons depending on where I am, I just can't program in a new APN or get rid of the Roaming icon no matter what ROM I flash, kernel or radio combination...
I have tried automatically and manually selecting my networks also, no dice...
I have of course already gone to *#*#4696#*#* and changed settings and tried all the variants but currently have it on WCDMA preferred.
I have also gone to *#2263# and tried all those variants but left it on WCDMA All Channels.
So I am more than open for any suggestions.
Go to Sammobile.com & search for stock firmware for your country/carrier (or just your country if they don't have any carrier specific firmware for your region), flash this firmware via Odin following whatever instructions Sammobile have for firmware downloaded from their site.
Once you've done that, check your APN setting & see if you have full connectivity. If for whatever reason your APN settings are blank (if you only end up downloading/flashing a country specific firmware only, for example), call your carrier for the APN settings and then enter these manually.
First thing you do when you have these problems is go back to stock & see if you can reproduce the problem or whether going back to stock fixes same

Thanks alot for your response MistahBungle.
Well on stock firmware is where I originally have the problem, that's the reason I began flashing ROMs and radios. IF I use a SIM from the original carrier which is Claro then all is well. BUT if I use a SIM from one of the other two carriers then the phone signal says roaming and I can't save any APN settings, no matter if I'm on stock firmware or any of the other ROMs or radio combinations that I have tried.
OK. Looks like we'll have to dig a bit deeper
So do you have baseband & IMEI in settings/about phone ? That issue of not being able to save APN settings with those other carriers sounds to me like a SIM or network issue. My first thought was it's a problem with the baseband, hence I suggested to flash a stock rom. But if that was the issue, you probably wouldn't be able to enter APN details for any sim/carrier.
Actually, now that I think about it. You know what it sounds like ? That the phone is network locked to your original carrier. That would explain everything.
If your phone *should* be locked (like you're on a contract where you only 'own' the phone at the end of the contract, etc), then I guess you can either pay the original carrier to unlock it. Or you can try one of the many unlock methods you can read about on here/apps you can get on the Market. Or if it shouldn't be locked yet it is, maybe ask the original carrier to unlock it.
You could also try flashing a specific rom for one of the other carriers, but I'm pretty sure that phone is network locked.

Ok just to clarify... all that makes sense, but what is ODD to me is that I don't think the phone is locked... I have full phone capabilities. I can make and answer calls, send texts, I even have full internet capability (even if I can't save any APN settings and there are none to be seen in the menu to choose from), I have the full speed of what I'm paying for from my carrier... the phone just won't let me SEE what APN settings it's using and in the signal it says R for roaming, but in networks it shows that it's connected to MY network...
Yes my IMEI does come up, BUT when I try one of those unlock apps I always get the message that it was unable to unlock it, but it's working with my carrier.
Ahhhh. OK. Yep that's a bit clearer now
OK. So we're pretty sure it isn't locked. That is really weird that it won't let you enter APN settings (regardless of which rom you're using), but you still have internet connectivity. Again, showing your network as the network connected to, yet showing up as roaming on the taskbar, is weird.
I've gotta say I"m pretty much stumped then. Haven't read a similar situation on here in the 4 mths I've been following the Q&A section of the board pretty much every day. Sorry I can't be of more help
Hopefully someone better qualified that me reads your post & can help. If you don't get a reply in a day or two, give it a bump.

Hey don't apologize, as you see no one else has ventured to give me a response either and I'm completely stumped myself. I looked for 5 days for an answer before I started a new thread because no one will go off on a noob for not searching quicker than I will, but I just haven't seen anyone with a similar situation on any forum anywhere...
THANKS AGAIN!!
Now to the rest of you devs, come on help a fella out and tell me what files I need to be looking for or modifying
Ok MistahBungles I got an update for ya... I decided to download a different firmware package (the PDA and Phone match mine but not the CSC), it's for Claro Argentina, BUT the ROM isn't branded when I booted it (the ROM the phone came had a CLARO boot logo (another reason I started looking for a different ROM)) and THIS ROM automatically has my APN settings in the menu without me doing a thing and the R in the signal is gone....
So now my question is how do I go about flashing the ROM I wanna use which is CheckROM but not lose my new found freedom (I ask because I'm not sure if this is a simple radio issue)

The Phone maybe Network Locked.(Not sim locked) As taken from gsmlocker.com:
Q. What sorts of locks are there?
A.
- lock phone to SIM
- lock phone to OPERATOR (network lock)
- lock phone to CODE (product lock = offer lock)
If your phone is locked to the sim you cannot use any other sim than the one you have: SIM broken makes phone useless.
If your phone is locked to an operator, you can use any SIM from this operator in your phone. You can switch between contract and prepaid as you wish, but not to a different operator.
If your phone is locked to a code, the phone checks a special "password" (GID) on the SIM that must match your phone. Providers often use different passwords for contract and prepaid.

OK I get your point BUT the phone if fully functional, I'm using a SIM from a different carrier, I have a data connection, make and receive calls, the whole nine yards, it just won't let me see what APN setting it's using and the R symbol is in the signal... once again, IT IS allowing the use of a different SIM from another carrier
Yes its the same as me! I have the R showing as well.(if you put the Claro sim in the R will disappear yes?)

Yes when I use a CLARO SIM the R disappears....
BREAKTHROUGH... I think that I have found the culprit... since I live in Costa Rica I use Market Enabler... apparently whatever it changes is causing the problem, which is weird because I have 3 other android devices, I use the same app on all of them and don't have this issue... NOW I'm really scratching my head... guess I need to contact the dev?
Ahhh. So Market Enabler is changing the CSC which is causing the network settings to disappear/barf.
Nice work finding the source of the problem Yeah tell the dev. Hopefully they can find some sort of fix/workaround so you can still use Market Enabler.

Well I just through and installed and tried ALL the market unlocking apps and they all apparently do the same thing and causing the same result, my phone thinks it's roaming, so now the head scratcher is why my other Android devices don't behave in the same way? This is my only Samsung. The others are Dell Streaks.

Sorry to bump this up, but I'm having the exact same problem. I was wondering if you ever figured out how to fix it.
I have a HTC Sensation and it happened to me right after I upgraded my custom kernel version to a newer one.
I never installed Market Enabler nor Market Access but when I check the SIM info it shows incorrect MNC and MCC values which
I can't change... they won't save in the system options.
I thought maybe my SIM card is screwed up, so I'm thinking of getting a new one from my service provider.
I just have to check it on a different phone first.

[Q] Using phone abroad, can't connect to data network

Hi everyone, I've read quite a few discussions on here but this is my first post.
I've recently moved to Sweden from the US with my sprint lg g3. Before I moved, sprint told me that my plan covers me to use voice and data for free, but only with a specific carrier. They said that it's already taken care of and I shouldn't need to do anything when I get there.
That was one week ago. I've been in Sweden for a week and every day of that week I've spent around an hour on the phone with sprint trying to get my phone to connect to the data network. I get voice just fine, but, from what I understand, the phone is wanting to connect to a different carrier for data and he doesn't know how to force it to connect to the right one.
So, after some digging, it looks like I might be able to create a new apn and maybe connect to the right data network that way? Going down this path, I can't by default add any apns, so I followed another discussion and installed root tweaker to be able to fix that. My phone is indeed rooted on lollipop, but the tweaker doesn't seem to change anything for the apn screen, I still can't add nor edit them.
So, my two questions are, should I even be messing with apns (and if not, what should I be doing), and if I should mess with apns, how can I edit it/make a new one?
Thanks so much in advance, I'm getting frustrated with the sprint guys so I'm trying to take some initiative myself.

Try flashing (in recovery) my "MegaAPN" file. It should support a HUGE amount of carriers. You may also need to unlock your apn's so you can edit them. You can do that by searching for this: com.lge.hiddenmenu.settings.ApnUnlock in shortcut master (lite or pro) and clicking the name of the shortcut then just press the "Launch" button (looks like a little Space Ship). Then just press the little "Unlock APN" button and Reboot. You should now beable to add/edit and remove APN's.
Hope this helps:good:
Hi!
I've tried the shortcut master to unlock my apn, and a dialogue bowstring my apn is unlocked appeared, but after a reboot I still have no options to add or edit an apn.
Luckily I do know the carrier I need to be on, and I've found the apn information for that carrier, I just need to be able to add it in the phone I guess.
Thanks for your help!

Galaxy S4 I545 (Verizon) outbound text msgs not working with Tmobile SIM card

Hey everyone. I just bought an unlocked, unused (new) galaxy s4 I545 (Verizon) and it wont send out text msgs with my T-mobile sim card. I do receive (inbound) text; but no outbound text msgs. Calls and web surfing work fine.
I'm aware that this is very common problem when trying to go from Verizon to Tmobile with galaxy S4 phones, but i have not been able to find a straightforward solution to this exact issue. Has anyone been able to solve this? I did find this one thread that addressed this problem, but it's quite confusing --> http://forum.xda-developers.com/galaxy-s4-verizon/help/noob-s-stuck-oc1-lollipop-t3116732

I tried changing all the APN settings. These are the same ones T-mobile had me switch. There is another post where the user discovered his SMS/MMS works when on 3g, but not 4g. The workaround was to Root and then change a setting to use only 3G. My problem is that I cannot get Kingroot or any other app to root my phone. They all fail.

What build are you running?
F1
I was able to root my I545 yesterday after months in limbo........ I used Kingroot (not Kingoroot). I tried it 7 times from the phone, and it failed.... then as recommended by many users, I scrolled to the bottom of the kingroot page on phone (after root failed). It said I should use the desktop to root it. Soooooo I set Google translate to "English" and loaded KR (Kingroot) on my desktop.... It WOULD NOT open Kingroot. So (on my desktop) I opened KR WITHOUT english translation. and it was running (on my desktop). Once it was opened, everything was in Chinese (of course). BUT.... it has screenshots that walk you through it (although in Chinese). I attempted to root the phone (by using screenshots only, since I do not know Chinese), and it rooted it first time My advice, use Kingroot as described using your DESKTOP computer and cable. That should do it
NOW my problem, is I have to flash my VZW S4 (OC1 lollipop), to a t-mobile rom...... so I can have wifi calling with my dedicated number Of topic:..... if anyone can do some Q&A with me on that topic I would be appreciate it GREATLY.
Hope that helps ya
---------- Post added at 08:30 AM ---------- Previous post was at 08:09 AM ----------
BTW.... I have the same issue with my text messages (no outbound sms) when I am on 4G. There is a write up on the forums on how to possibly remedy that, but I get hit with.... "MD5 has to many hashes" and I cant go any further... Im still trying to figure out what the hell MD5 is.
ATTENTION to MODS, and OP's:
I am seeing more and more people (like me) whom are coming to XDA because they have a Verizon S4 (whether its kit kat, or Lollipop), and they are using a T mobile sim. I have made an assimilation though.... These people that are coming to XDA have little, to NO root, rom, kernel, experience what so ever (just like me as well). IWe are looking for a fix (I myself want to flash my phone to a T-mobile rom, activate wifi calling, and be able to send/recieve sms continually). Is there anything that anyone could write to address JUST 2 things......... (1 how to get a Verizon S4 with kit kat, and with lollipop to have a t-mobile rom, 2) If somone elects to leave the phone a Verizon phone, a step by step (tailored for noobs like me and many many others) process for fixing the sms issues from having a T-mobile sim... The write up for the second request thats out there is okay, BUT the common problem is a "MD5" issue when you try to download hiddenmenu.apk. Without being able to download the "hiddenmenu" to our phone, we can't even get to step 2 of the "fixing sms issues"...
Please OP's, and mods........ remember in this tense world we live in, remember one thing......... "NOOB LIVES MATTER!"...... C'mon noobs, say it with me! :good:
I don't think the ROM matters. As long as it's a Verizon variant of the phone you won't be able to flash T-Mobile ROM's. This issue is most likely an APN setting issue. Did you ever try flashing the stock OC1 build for the VZW GS4?
I have the OTA lollipop update.... it came in two parts. The apn settings are set per tmobile . I can send sms however only when it switches to 3g. The problem is, on lollipop, you cant toggle between 4g and 3g like kit kat would allow. So its hit and miss (much more miss than hit...lol). From the sounds of it, the radio mhz are different between vzw and tmobile regarding 4g. The other dilemma i have is that i live in the mountains of oregon so i am 3 miles outside the network.... therefore i need wifi calling. I have a google voice number, but i need my assigned phone number for work purposes.
If what you say is true regarding a rom specific for vzw, i guess i need a vzw based custom rom, that will allow me wifi calling, and also fix my sms 4g issue...

Speaking of the 3g and 4g thing...... since i have rooted my phone (via kingroot), and installed supersu, am i able to turn off 4g? And if so, how do i do that?
No, you need a T-Mobile ROM that has wifi calling enabled. But like I said this is probably more an APN setting issue than any.

This ^^^ is a link to the manual if you think you can find something useful in there. I've used like 20 apps that all claim they can Toggle LTE data but I've yet to find one the doesn't just bring me right back to the settings of the phone. I've heard rumors about an app that's $1 on the play store that can do it for the GS4 but I can't confirm that. It seems as though you need some special settings provided by the service provider in the ROM that allows for such changes. I might recommend looking into whether you can flash a T-Mobile ROM to the VZW variant.

Thanks for the link for the manual. I just checked the APN settings, and they are where they need to be. There are only two different settings/entries that i have found for mmsc, and both leave me with this problem. I have researched, and can find a fix for it if i had jelly bean, or kit kat..... but i have lollipop
I am searching to see if this vzw phone will take a tmobile rom (or a variant). If it will, than i might be in business. Does anybody know if i can roll this back to kit kat, or jellybean since i am now rooted?
Unfortunately once the GS4 is on the 5.0 build the phone's bootloader does not support downgrading-I've tried. I, like you, have a the lollipop build (OC1) on my S4 and I really wish I had not taking that update. Lost story short it was an accident I shan't repeat.
finally got it working
I also ran into a wall after taking my wife s4 i545 from Verizon to T mobile. I finally got everything working. the phone is on OF1 so there's a lot of things you need to do they are all here but scattered and very hard to find. you need to root with wondershare mobilego. then you have to odin flash an OC1 kernel then change the settings to the T mobile settings then get this app called Advance signal status and change the defaul text message number from the verizon to the t mobile number and the mobile networks there too(you want GSM auto). after all that you'll be on 3g or H+ for your data but its not too bad and everything else works great including text. total time about 1 hour but just putting things together is where your time goes. hope it helps
Note if your T-Mobile SIM used to be in an iPhone
I was having crazy trouble getting my SMS and MMS working with a stock Verizon Samsung S4 (SICH-545) ROM. I believe most of the problems I had were due to the fact that I was previously using an iPhone4 as my T-Mobile device. After searching through the internet and finding the proper settings for T-Mobile APN, I was able to quickly get phone calls and 4G data working. However, there were some things that took a while to get working. Initially, I could receive SMS, but not send SMS, nor send/receive MMS. It's now working and here's what needed to be done:
Remove the phone from iMessage (allowed sending of SMS)
Remove the phone from iCloud (allowed sending/receipt of MMS)
Lastly, to ensure you get Voicemail access, change the Voicemail number in your Settings. To get directly to VoiceMail with T-Mobile, dial '123'. There's a different number for accessing from a different phone, but this works directly from your T-Mo phone.
I did not get a chance to read all of the responses on this thread, however, I can probably help resolve if the answer is not already embedded in this thread.
I have successfully rooted a Verizon SCH-I545 with stock Verizon ROM and got SMS/MMS to work. Unfortunately, I have only been successful through locking out LTE. If you want more detail please IM me. Otherwise, here is a quick overview:
1. Root SCH-I545 (There are a handful of methods but Wondershare MobileGO seems to do it for me.)
2. Update APN’s to T-Mobile (fast.tmobile.com)
3. Download Advanced Signal Status. Change Data Signal to lock GSM/CDMA (PRL)
4. Reboot and Enjoy
Worked on several handsets I have flashed.
NOTE: A simpler method would be to flash ALBE95_S6 using Flash Fire then there is no need to deal with locking your data signal through Advanced Signal Status, just use the default Network Settings within the ROM.
Hope this helps.
That doesn't work for me. I can't access Additional Info, AND even when I could, DATA would disconnect... so I'd have calls and texts.. but no data.

Change the smsc number to +12063130004 and the network mode to gsm (auto) using advanced network status app. You'll need root and the latest supersu binary

I did the same, flashfire albe s6, rooted, busybox, apn change, advanced settings gsm/umts, lost wifi too, but....
I was able to fix it. There is a wifi fix in one of the earlier posts: http://forum.xda-developers.com/galaxy-s4-verizon/general/gogolies-wifi-fixes-t3099951 forgot which one I used. but it all works now (on tmobile that is)
Oh, in case you went and downloaded the latest ota from verizon (f*** you very much), like I did, lol, there's a wifi fix for the OC1 bootloader too, for us flashfire people: https://www.androidfilehost.com/?fid=23991606952597069
here's the directions, nice and slow
root the phone, I used kingroot, then converted to supersu, then install busybox
then install safestrap, if you can (your bootloader is older than and not including OC1) or (if you went OC1 or newer), then install flashfire, like I did. Only thing is, if you muff something up and only have flashfire and not "real" recovery, other than the stock one, it gets kinda stick fixing it, (you have to odin in the verizon stock full image of OC1 and start over, I think, I forgot).
then I installed albes s6 rom, I think its in the unified or maybe att s4 section. its easy to find. Its prerooted, so I just updated busybox and then re-installed flashfire. when you install albes make sure you do a full wipe and flash the oc1 bootloader after the albe rom, in flashfire, that's the only way it'll boot.
ok, so you got albes, now you need to change the apn. I use idoneapp gt 3.8. The guy doesnt give it away for free anymore, and I don't blame him, I was just lucky enough to grab 3.5 (which you need to install 3.8) and 3.8 before he decided to charge for it. Its for the sprint s4, but it allows you to do alot of stuff, even on the verizon variety (lol). You can change the apn, allow wifi tethering, get into the advanced menu to change the radios (gsm, cdma, wcdma, lte, etc) (or you can dial *#*#4636#*#* - sometimes doesnt work though. There are other apps on the playstore to change the apn too, so change it after you do all that other stuff. make sure you have the mmsc and everything else correct for tmobile. I have mine set on lte, gsm, cdma, which seems to work for everything, voice, data, mms. Anyway, good luck and have fun! If it doesn't work, oh well, I bought mine for $13. I also have 3 other s4s, a sprint l720t, the cricket one, and the 970 us cellular. I cant get the cricket or the us cellular to take the tmobile sim, even though I flashed the radios to gsm and the roms to tmobile (pain in the a**), but I think those, although they do have the radios, don't have something else hardware wise to allow gsm, since they are both exclusively cdma. I found the sprint one, paid $10 for the cricket, and $22 for the us cellular (it was brand new though). I get lucky on ebay, people think their phones don't work and they do. I've take all of them apart many times, and most times they just need the usb,mic ribbon cable, which I can get on ebay for $1.89 (there's 2 versions though). Late

Unable to connect to my mobile network

I recently purchased a refurbished phone Samsung Galaxy S21 5G. I just got it yesterday, and found that I am not able to use my mobile network. The sale said it is factory unlocked, and according to the descriptions, it should work just fine with my US Mobile SuperLTE network as well. When I switched on the phone, I see Verizon on the screen and so, I assume that it was locked to Verizon in the past.
When I tried to change the network settings, specifically the APN settings, I get the message "Access Point Name settings are not available for this user." The three dots on the top with reset to default is also greyed out along with Network mode in the previous page. When I click Network Operators and try to connect to the network manually, I am only able to connect to Verizon Wireless and no other. But, calling and messaging seems to work fine. Is it that the unlock process has not been completed properly? Did any of you face the same problem before? It would be great if there is something that I could do to unblock the APN settings as the rest of the phone works really well. The specific model is SM-G991U.
Thanks!

So, you need to go into the settings menu and find about phone, software info. What you want to find is the CSC information.
It will basically look something like this: XAA / XAA-XAA / XAA (or some other letters like VZW or ATT or TMB etc etc.
What taht will tell you is very helpful in determining what rom the phone is running and what kind of device it was originally. Find that in your device and post it and people will help you to figure out what it means.

Thank you so much for your reply. I looked through the software section in the about section. I found the following codes about the rom.

So the csc info is complicated, I'm no expert on it. But it does look like the OYN indicates it's a multi csc rom. It does have XAA as a part of the code, and that indicates it's 'open' for that specific part. But all the others are VZW. So it's running a vzw rom, obviously.
Your sim US Mobile uses both verizon and t-mobile networks. So it working for calls and texts makes sense, as a vzw phone. You could use patched Odin and flash a different (open) rom, but first you should verify that the device really is unlocked from vzw.
Best way to do that would probably be to insert another carriers sim card and see if it can make calls / texts. If not, it's not unlocked. But are you saying everything works now except mobile data? IOW, no internet access?
I had an international sim card at hand and I put it in. Interestingly the APN settings are no longer blocked. But, I do get a notification from setup wizard saying the inserted sim is not from Verizon and some services may not be available. But, messaging still seemed to work and I was also receiving 4G.

Oh then yer okay. That message from verizon can be gotten rid of a couple of ways; 1) use adb commands to disable the specific packages 2) use patched Odin and flash a different rom
VZW is the only rom I think that does that, and it's very annoying. I don't remember exactly which packages have to be disabled, but search google and use xda and vzw in keywords and u should find it.
The 2nd option would be my choice. It would do away with vzw crap and with an open rom you may find volte and vowifi will work also.
cheers
Thank you so much for your reply. That sounds great! To just give it a try, I tried putting in a TMobile sim and phone restarted to install software for TMobile. After that the APN settings were unlocked and now I am also able to connect to the internet using my US Moblile sim. The only problem is the the network mode is greyed out.
This rom I think only recognizes network from major telecom providers. So, just flashing with an unlocked rom would just help to unlock all the features and also remove telecom specific crap. I will try to flash it today.
Thank you again!
I also just flashed the stock firmware which is fully unlocked. And there is no bloatware from telecom OEM's. I am now able to use the network and set the APN's, but the Network Mode is still greyed out. Is it possible to know why? I am guessing that if the phone is fully unlocked, I should be able to change the Network Mode. Is there any other info that I can give you to help understand what is happening? I do not see vowifi as well.
