[Q] Is it ok to flash Cyanogenmod for verizon to US cellular phone ? - Verizon Samsung Galaxy S III

I asked somewhere else but I found a lot of references here so I ask again
I would like to use my phone which is originally a US cellular phone on Page Plus network. I think it will make it much simpler for me to flash a Verizon cyanogenmod (not the stock one ) to my phone b/c of defaults network settings, etc.. I think that way it will work out of the box !!
Is it ok to do that or it will brick my phone ?
The reason I wanted to do so was because I was following some tuts about flashing USC phone to pageplus which required dialing *#22745927 to enable Tap Qualacomm USB Setting and DM+Modem+ADB or something like that.
But without the USC sim, the phone refused to accept *#22745927 or anything, it said network not available. With the USC sim in, the phone rang for a few secs then a voice said my account is not authorized.
That is why I thought I should flash the phone to VRZ to begin with.

How to activate my Droid 2 Global?

I got my lovely droid 2 global (white) today, which is amazing. However, when I turned on the phone, it required me to activate. How can I activate it in Toronto, Canada without in US? Thanks.
Exit that wizard, switch to GSM/UMTS and you are ready to go (assuming you unlocked)
hi all,
i've been using my lovely Droid 2 Global outside US for quite a while (unlocked and using GSM network), and it worked all fine till today...
i tried to install fission today, and it didn't work for me (it just won't boot up), so i restore to 2.3.29, and finally managed to boot it up...
but after i power up, and enter PIN for my SIM, it requires me to Activate the phone...when i hit Activate, it immediately show "Phone Activation not supported on this network"...any suggestion on what i should do? i think i have the unlock code that i got from the buyer, but the phone doesn't even give me a chance to enter it!!!
i don't need to use Verizon network, i just want to use my D2G under GSM!! Please help!
i should have asked: why i need to re-activate again simply bcs i restore from a SBF??? I thought it shall stay as activated and unlocked once it was done...am i thinking wrongly?!
Don't freak up. Activation is only for CDMA radio. Every time you do factory restore (wipe data) CDMA programming gets erased too. GSM radio doesn't need activation. Simply ignore this, switch to GSM/UMTS mode and start using your phone.
If you have US account and you want to reactivate so you can use CDMA roaming feature, you need to do manual activation, but you may need Verizon's support to help you with some numbers you need to put up in programming.
BTW - the boot loop happened because you didn't wipe data after SBF. Fission (and any other non-stock ROM) will cause boot loop if you don't wipe data after SBF flash. (SBF flash process does not wipe data as part of the flashing).
GSM radio need to activate to use outside USA ! You need to contact with Verizon to get unlock code or use some unlock sim

You are mistaking unlocking with activation process. On GSM you activate the SIM card (Subscriber Identification Module), while on CDMA the "SIM" is integrated in the radio, hence you activate the radio.
For Droid 2 Global since it has essentially 2 radios - a GSM and a CDMA one, for GSM you need active SIM card to activate and for CDMA you need to make sure phone's MEID is active on your Verizon account then you program it (activte) either automatically while on Verizon network by dialling *228 or manually by calling Verizon support.
For the GSM radio in D2G, in order to use non-Verizon SIM in it, you need to unlock the phone first. Once unlocked, phone remains permanently unlocked and no SBF or wipe or anything will change this status.
Hey guys. I just bought an unlocked D2G on ebay so I thought I would share my experiences.
I got to the same screen where I was told "phone activation not supported on this network" and it was extremely frustrating. my only option was to hit ok and go back to the "touch the android" screen. I tried everything including the menu button. Nothing worked. This was with my SIM card inserted.
So I took out my SIM card and tried again. this time the menu button worked; it brought up the wireless options menu. I wanted to switch to "GSM only" as I had a feeling that would fix the problem. But I was told "no GSM card, must use CDMA mode". So, feeling stuck, I called Verizon, and after waiting on hold with the first CSR, and getting about 30 seconds into the phone call with the high up tech guy, I was in the middle of telling him about how in CDMA mode the wireless options menu would come up, but not with a SIM card inserted, the wireless options menu actually did come up. So I switched to "GSM only" and I was in!
Well, sorta. I had to get the phone linked with my google account via wifi, because the phone had no internet at all. A quick search of the internet revealed that this was a common problem - "I can talk on my D2G, but no data!" I called Rogers and sure enough, there were some settings I had to change to make this work.
Go into wireless options, then mobile network settings, then GSM/UMTS options (I assume you have a D2G because you want a droid you can put your SIM card in, right?) and then to Access Point Names. As this phone is unlocked, there are no APNs listed and your phone is neutered until one is added. I had no idea because my last phone was straight from Rogers and was of course hardwired to know this stuff.
Setting up the APN is really easy. just give it any name, list the APN as internet.com, MCC is 302, and MNC is 720. That's all. Back out. You will notice nothing is showing there. Don't do it again. It's there, but it's not showing up until you reboot. On my first reboot I had the 3G icon pop up in the notification bar and just about filled my pants. finally, the phone I paid $400 for was fully functional! No issues since then. Smooth as butter.
Thanks for the information and sharing leobg and seventieslord!
Gingerbread's rolling out, I'm planning to update my dad's D2G, but we're outside the US with an unlocked phone using GSM. I was worried after updating to Gingerbread, the phone would ask for a reactivation. This thread put my mind to rest

[Q] Droid 2 Global

N00B here! but tried to gather as much info as I could..
Got a VZW droid 2 global from ebay that the seller profiled as "unlocked"
I'm in Central America and trying to register it with a GSM 850/1900 carrier but it won't connect to the network at all.
It had a 14 IMEI code... found it's translation to 15 to 17 IMEI and bought a the unlock code on a site. I got the unlock code but the phone has nowhere to enter it.
Found a post stating that it should ask for the code after inserting a foreign sim card or waiting 30 minutes if nothing happens. tried that and there's no prompt.
I have accessed the testing menu with *#*#4636#*#* and select the GSM only and WCDMA preferred (I got an HTC Inspire 4G working with that one here) and it is recognizing the GSM 850/1900 local carriers but unable to get any network access from them.
Found that VZW locks the carrier's network ids but the phone is recognizing them.
Again: ir recognizes the networks but is not asking for an unlock code... all the posts states to enter the code but they don't say how (the phone must prompt it automatically)
Please let me know if there is any way to manually pull up the field to enter the unlock code or if I can try anything else to unlock it
Thanks!
First, the phone's IMEI is written on the label under the battery.
Second, if you switch it to GSM mode it will output the IMEI in *#06# and in Settings, About phone, Status.
The 14 digit code you mentioned is probably MEID in hex form.
Switching to GSM is done by going to Settings, Wireless & networks, Mobile networks, Network Mode.
Using the service menu you mentioned is wrong and can lead to the phone being unable to connect to GSM at all, in which case you must reflash the SBF.
Actually I got the unlock code but there is nowhere to enter it.
Also it allowed to me to at least view the available networks after changing it to GSM/WCDMA and seems to be trying to connect to one but there's no signal at all.
If I do a network search now it will show me the available networks 5 or 6 (2G&3G), selected one and it just shows that it is not able to connect to that network
BTW, found that the radio was off as well and had to switch it on using the testing menu because by going to Settings, Wireless & networks, Mobile networks didn't allow me to access it at all, it was just grayed out and there was no way I could turn on the radio using that option..... sorry... I think I got everything I need except where to enter the unlock code
It looks like you have successfully (like other people before you) fried the GSM radio settings. Congratulations.
You need to flash the SBF to reset the phone's radio module to its original state.
If you actually bought a phone that was already unlocked it won't ask for an unlock code.
A locked phone asks for the code the moment you power it on and let it boot with a non-Verizon SIM card.
The code you supposedly bought is not for your phone at all, because you requested it for an IMEI you made yourself from something that was never an IMEI.
For me, The unlock screen appear only on original rom with non-verizon sim.
not appear on custom rom.

weird network lock?

Hello
I just recently got the optimus 3d. its brilliant!
With the help of this forum I've managed to root and get Clockwork then install thais rom.
amazing speed increase.
But i have just one issue.
My phone was locked to orange uk provider. when i bought the phone I had to call orange to have my phone 'activated'
only after i did that did the phone even receive a signal.
before that it just said emergency call only, or no signal.
now, i've unlocked the phone using a code. it now says no personalization when i check the lock menu.
but: when i insert another sim, vodaphone uk or 3 uk, it says emergency call only or no network.
whats going on?
please help...
thanks
after a search it seems other people also have this issue with no reply.
did anyone else have this problem and fix it?

The activation bit is for the sim card, I have a phone locked to O2 and what happens is you register the sim with them and then they enable it to use their network which is why until then it will say no network.
It is also the reason why if you put any other sim in the phone, and that sim has not yet been used to make calls, you get the same error.
As for the personalisation message on the unlock menu, I am unsure what you mean by the lock menu. I assume you mean the screen you see before you unlock your phone to use it each time, and did a search on google which produced no results but I would guess that if you are using a custom rom the message means you either have not personalised your screen or that the option is there to personalise it but has not been used.

unlock menu - where you enter the network unlock code.
i'm trying to use my 3 uk sim, its been on contract for over 2 years.
I know that a lot of unlocked phones wont work with 3, if you google 3 unlock you will find a lot of people have problems and some unlock companies even specify they wont unlock to 3 network but if it does the same with non 3 cards or only works with one operator perhaps the unlock was only partial?
I did a search for pedsonalisation and all I found were various unlock sites saying that a sucessful unlock needs you to have a personalisation menu.
My previous android phone had a device lock and a sim lock, could it be your unlock has only partially worked? Is it only one provider whose network you can access?

you're being really helpful so i give thanks.
i have tried o2 and vodafone sims in the phone also but to no avail... always says emergency only or no network, with both showing no signal.
would flashing the original orange rom back then retrying the lock code help? as of right now when i go to the unlock menu and click network lock it prompts a message stating my phone has no personalization.
sorry missed out a little bit of info.
the only network that works is orange, it gets full signal and works perfect, but i'd really like to use my contract sim instead of pay as you go extra on orange.
I've done some more searching and found that on a lot of phones that personalisation message means the phone unlock has failed and that after a successful unlock it should say something like "network lock has been personalised".
You do only get a certain number of tries so don't enter the code over and over, if you are sure you entered it correctly it means the code you got just didn't work (I had that when unlocking my previous LG and had to buy a code from somewhere else as the first one didn't work at all).
I am not recommending this site, it's just one that explained how to unlock so am posting a link in case it helps, but the site says you need to enter two codes on an Optimus 3D. One is for network lock and one for service provider lock, I know that some people on the xda forums have unlocked their phones so I hope they will jump in and help solve your problem as really all I can do is google for the bits I am unsure of but it would seem your code did not work, or that you need two codes and only had one.

just wondering if i could post a video link here to show how it happens, if not, mods can you delete this link:
http://videobam.com/YqMQH
might need to tilt head/computer screen
that was with orange sim, without orange sim it shows no signal and no network... its running thais rom.
heres a video of it using another sim.
when i start the phone with other sim, it prompts whether i'd like to use mobile data or not, but no connection!

Well having watched your videos I can clear up something, I think.
I had searched for terms based around "no personalisation available" which means your code did not work but searching for the actual message in the video "your phone is not personalised" produced completely different results.
That specific message means the option you are clicking on is not locked (not personalised by your provider) at least according to various pages I have found including a few on other well known Android forums so if that's correct your unlock did actually work and that is why the message appears.
The page at http://www.cpkb.org/wiki/LG_enter_NCK_code also mentions this code and its cause.
If the other sims you try offer you data or mobile but do not connect, yet you can make calls, then you need to set up your apn for that provider. The apn tells your phone how to connect to your provider.
This is really easy to do but you will need a free app called Apn global from the android market at https://market.android.com/details?id=osatek.apn.global obviously you need it on your device which can be done in various ways, possibly easiest if you can connect via wifi and go to the market.
Install and run it, pick the name of your provider (the provider whose sim you wish to use) and it will create the mms and internet settings for you. Then mobile data should work.
Alternatively if you have an android phone which you already use that sim on, install to that phone and choose the apps backup option which will backup your exact settings to sd card so you can import them to another android phone.
If you have other providers apns on there you will probably need to tell the phone to use your new settings. Simply go to your phones settings menu, find the wireless settings option and click it then scroll down the screen to "mobile networks" and click that. Then click "Access point names" and choose the desired provider. I have three on my phone and you can always revert to any other settings if you change provider later.
The apn app is very useful, I have used it on a few phones, it has a large list of providers worldwide so you should find your choice of provider there and hopefully that will solve your problem.
Dave
Thanks for the reply dave, but I have yet more bad news sadly.
I can't actually make calls, as shown in the second video it shows no network/emergency calls only.
It's hard to believe no-one else has this issue.
I have owned lots of android in the past(started with g1, then hero, then jumped to zte blade then galaxy 1, now this) none of them posed any difficulty removing network lock.
Its such a strange problem that a search of this forum shows at least one other person had this issue but no-one could help.
Sorry if this sounds stupid but have you gone into the settings menu on your phone (Settings/Wireless and Networks/Mobile Networks/) and chosen the "select your network provider" option?
There you can force your phone to use a specific network provider.

I have with error "Unable to connect to this network at this time. Please try again later."
I don't think I can help, though I did some more googling and on the cyanogen mod forums someone posted a similar problem....
I've been using the nightly builds of CM7 since they came out and have had no network problems. I then installed version 7.0 [stable] when it came out, and just yesterday I installed version 7.0.3 [stable].
I have had no signal since, and whenever I try and select my network from the Settings > Wireless & Networks > Mobile Networks > Network Operators, it comes up saying "Unable to connect to this network at this time. Please try again later.".
It is nothing to do with my network provider, as my brother's phone works fine and he is on the same network as me.
I am on Three Mobile.
Please help!
RESOLVED: I just wiped all userdata and reflashed CM 7.0.3, I'm a very impatient person

If you fail to get a solution this option may help but probably best as a last resort. One thing I did notice when watching your second video is that you have the wireless on, this will stop your phone connecting to any providers mobile data so at least as far as mobile data goes you won't be able to use it when connected to wifi and would have to switch wifi off in order to test the mobile data connection.
Also I know that on my O3D my wireless sometimes seems to cause my phone signal to switch off with the little x. I doubt that is the cause of your problem but may be worth trying to connect with no wifi.

I'm going to try reinstall the original orange rom that came with it and downgrade baseband, if that fails to work after a full reinstall using lgflashtool I'll have to try get another phone.
thanks for all your help dave, i really appreciate it!
A popular unlock site says the only steps needed to unlock to any network are...
1. Input a non accepted simcard
2. Phone will display enter “Sim network unlock PIN” or “Enter Network Unlock Code”
3. Input the 8 or 16 digit unlock code that was emailed to you
4. Phone is unlocked!
If you did this, which you obviously have, your phone is unlocked and the problem must be something else but if you're going to flash a copy of the orange rom you might want to check first with one of the more knowledgeable users here that the rom won't replace some of the locks you already removed.
I checked around and from what I have found it should be as easy as put the new providers apn on your phone, select their settings from mobile networks menu for provider and also mobile data and that should work.
One orange customer who unlocked a different model android phone found that all they had to do was flash the radio only (not the rom), not sure how you do that but there are probably guides on xda.
Dave
I flashed the original orange rom and after flashing the froyo basrband it suddenly worked. Flashed gb again and it still worked, seems i just hsd to reflash basebsnd/radio like you said.
Thank you so much

Hi pauliebb,
I have the same problem that you had. I bought a used unlock O3D vodafone ES to gift to my brother, he lives in south america and he told me that the mobile does not recognize his SIM. What did you exactly do you did to reflash the baseband firmware???
I supposed thet the mobile is unlock because it shows the same message when enter to the unlock options "phone is not personalised"

the same problem
i have the same problem, i have phone from plus gsm poland, phone is not personalizet but read only sim card from plus, diffrent card not read and show info no sim card, help me how resolve this problem?

SM-G920W8 | No Option To Connect to LTE

I bought an Unlocked Canadian S6 recently, and it just won't let me connect to the LTE network.
Model Numer : SM-G920W8
Android Version : 5.0.2
Baseband : G920W8VLU1AOCG
Connecting to the LTE is not even an option. When I go in the Network Options, I get the choice between :
-WDCMA/GSM (auto connect)
- WDCMA only
- GSM only
I know for a fact that I am in the coverage zone, so no need to ask that silly question
I've tried different SIM cards, played in the options a bit, and factory reset the phone about 5 times now, yet nothing seems to work.
Also, when I try to do the update, it just reboots and gives me an Android logo and a failed Icon
I've only seen one other post like this from a carrier's support website, but no solutions were found.
**Update : For a reason, after a recovery, it will connect to the LTE for a bit or until next boot, then go back to what it is now.
First question, who did you buy the phone from? Second, Is it second hand? By default, Wind mobile does not allow the LTE option to be displayed in system settings as they as a carrier don't have LTE. It is blocked by the CSC setting for the carrier. As for other carriers It should leave you the option to connect in settings where you say it is not. If it is a Wind phone, You would need to change the CSC to enable the LTE selection. There is a method to force LTE even without option in settings, but I think it is removed in the latest firmware. Try dialing *#2263# in the dialer. It may bring you to menu that will allow you to select LTE. This is not a permanent method though as it will need to be done every boot. The other way, (If you are in fact a Wind/Mobilicity phone) is to enter dialer and enter *#272*IMEI# with IMEI being your devices unique code. If at all possible, take a full nand and Titanium Backup before doing this and be sure to transfer everything off the phone to a PC. This method wipes everything and I mean everything off the phone buy is a surefire way to enable LTE.
Yes, it was second hand. I didn't ask who was his carrier simply because it was unlocked.
I'll try it tomorrow, thanks for the information
Here is the menu you will see when you type the *#272*imei# code into your dialer. The codes are the carrier names. Mine which is GLW is Wind, BMC is Bell, RWC is Rogers, etc.
Maybe there is no LTE in your area...

It would still be visible in the Settings/Mobile Networks/Network Mode menu which it is not. His problem is more than that.

Sweet! It works :good: Thanks man
Now, would you have any ideas on why the update won't work? I didn't get much into it yet, but I will soon.
I'm not sure why it wouldn't update, but now that you have changed the CSC you can download the update and flash with Odin. Pick your carrier and go to town. The guy running the following thread runs his own firmware host. He's got amazing DL speeds. Usually takes me 6 or so minutes to do the 1.6gb file. http://forum.xda-developers.com/showthread.php?t=3086387

Connected with someone selling a G920W8 version. LTE is disabled and the codes aren't working. Can you reaffirm which unlock code worked for you? I'm on Fido, what LTE network are you using?
hi BCSC
Thanks for the details. I searched complete net and read all articles but nothing set me up with the proper thing. i read your solution i dialled *#2263# and all i got is service mode and in that i went to band selection , LTE and the all ....... Yes and its showing LTE in mobile data. THanks so much.
But now another issue, network is showing perfect but no outgoing and incoming calls.
in incoming its showing busy and on outgoing its not connecting to another phone.
And, Lte is not showing in mobile networks, There only 3 options still are showing.
Mine is same Wind S6 but i had to use in India.
Let Me know
Thanks once again
Cheeerzzzzz

Picking LTE from the service mode will note make it visible from the settings menu. Its more of a workarpund instead of a way of permanently enabling it. As for the issue of no out/in calls, my best guess is that it could be due to which LTE bands are being used or are available in India. Unfortunatly I have no way to test that option. I only was successful in getting the Wind LTE option on Canadian carriers.

Can you flash ATT, VZW to XAA Branded in Download Mode

Forgive me if this has been covered but I havn't found the answer. I've flashed just about every phone I've ever had but my question here is can I / how do I flash to where the phone reads as XAA in download Mode?
The situation is my phone was originally on at&t. They unlocked it and I'm on Verizon. It all works great (it still says at&t on download Mode screen)
My problem is that if I log into the my Verizon app it disables my visual voicemail. I finally got a Verizon tech on the phone that explained that it is unsupported due to originally being on a different carrier and their system identifies that and disables the VVM. The only fix I can find is to put my sim in my backup S9+ that came from Samsung unlocked (or any Verizon phone) and I can then reactivate my VVM by resubscribing.
I currently have 3 Note 20 Ultras. One Each originally from Samsung, ATT and Verizon but the AT&T is the only one that is 512GB or I would just switch phones. I have flashed them all to U1 firmware but notice they all still reflect the original carrier in Download Mode so again my question is can I change this by flashing it / or is it just a matter of what sim card is in it when it's flashed? I need it to be seen as XAA by Verizon system so not to loose VVM... Pics attached.
Any advice here is greatly appreciated in advance.
Just a try... You can try the *#272*imei# method... But thats If it works. Not sure if the sims has to be in the phone for that to work.

Click to expand...
Click to collapse
Yes it brings up this menu... So I just select the XAA and that's it? I've been reading forums and this method is reversible it seems ... I'm familiar with Odin and all that but these hidden menus are new to me...
Thanks for the reply btw
You may have to activate the bottom most option to stay.
Don't worry if you can't access the menu after the change. You can download samsung band selection and change to automatic or one of the lte options then back to automatic to get to the menu.
CSC Guide
CSC (which I think means Carrier Service Code) helps to set what options for settings show in the device for things like voicemail and wifi calling, as well as sets network code information for things like carrier aggregation combos.
When you go to your phone settings->about phone->software information and look in the Service Provider SW ver. section, you will see as the last line a combo like XXX/YYY/ZZZ. This indicates what carrier sales and network code is set and what brand the phone was manufactured as.
I think of the XXX/YYY/ZZZ configuration as follows
XXX=Sales Code-What kind of features are setup in the firmware like wifi calling, video calling and settings menus
YYY=Network Code-What kind of network features are set for things like carrier aggregation and LTE/5G bands
ZZZ=Manufactured as Code- What model the phone was originally manufactured as. Ot has no affect on the system settings or options. THIS CAN NOT CHANGE. IT SHOULD ALWAYS BE THE SAME. ONLY A ROOTED PHONE WOULD BE ABLE TO ACCESS THE FILES NECESSARY TO CHANGE THIS.

Hello All, Many people have asked about service mode and CSC related questions and I thought we should get a discussion going that is all in one place. *DISCLAIMER* I do not take any responsibility for any issues that may occur from changing...
