[Q] Verizon HTC One M7 to AT&T - General Questions and Answers

I have my One M7 rooted and unlocked. It was originally with Verizon. I now wish to use it on Straight Talk (AT&T towers). Simply getting the SIM card and activating it does not cover everything. Due to the latest Android software there is no option to add or modify APNs. Therefore, I can not use data unless I am connected to WiFi.
I was wondering if I should (or even can) change everything to the HTC One (GSM) ROM from CYanogenmod so I can properly set up my phone to work on Straight Talk.
Any and all help will be much appreciated!
Thanks

[Q] HTC Mazaa activation on Verizon

This question has been asked two times already but in the middle of huge discussion threads and there hasn't been an answer yet, so I thought I'd try again.
There is no way I can find to specify carrier information or get into a "programming" mode via the provided Mango apps. I took it to Verizon and the IME was fine, but the programming codes for the Trophy didn't do anything on the Mazaa so they couldn't activate it.
I did pop in a friend's T-Mobile SIM card and it connected and worked just fine via that route.
I emailed HTC and they said they don't have that information and there is no unlock code since the phone isn't locked.
So, anyone have any clue about how to get this phone provisioned on Verizon? It's running the retail Mango as of yesterday.
Thanks in advance!
Well I have a trophy on Verizon now and I know how tough it is to get Verizon to work with you on this. I am going back to tmobile soon so I need a tmobile phone. Because it's unlikely you'll get the Mazaa to work on Verizon, I will happily trade you my mint trophy with box and all accessories for the Mazaa. I will also add cash or maybe my HP Touchpad with case and dock....
Im not trying to take advantage of you or anything like that, it just seems like it could be good for both of us.
PM me if interested.

lol that is because it is not locked. locked phones are only an issue with GSM phones. Verizon uses CDMA. Basically, t-mobile and AT&T use sim cards, while Verizon does not. You can not take a Verizon phone and use it for t-mobile or AT&T and vice versa. Simply not possible as they use completely different tech.
Yeah, I know the phone isn't locked. I already said that.
Do you personally know how to provision and unlocked phone to work with Verizon? The HTC Connection Setup says it can't find a database and exits when I run it.
Does anyone know if its possible to copy carrier specific provisioning information from a retail Verizon WP7 rom and inject that into the rom on my phone? The HTC Trophy seems to be the nearest match. At the least it would be great if I could copy over "the database" from the one ROM image to mine.
Open for suggestions here..
Sprint HTC Mazaa activation
I am also looking how to activate my Mazaa on Sprint. Sprint refuses to add it to their network and it can't even find a cell tower. When I look at the settings page and choose about the phone it appears to be setup for Verizon, although I don't have Verizon and can't verify this for sure.
How did u get the HTC connection setup app to even run? Mine immediately just says I don't have an HTC phone and exits!

unlocked is not everything.
GSM phones cannot be used in CDMA networks, and vice versa. What you need is a CDMA phone, to work with the Verzion network. (GSM and CDMA are not software matters, you cannot simply solve by flashing different ROMs)
Phone is Quad Band
Thanks but the phone is a quad band and can work on all of the carriers.
HTC Trophy Rom Dump
I grabbed the Trophy ROM and looked at the image. There is a folder called operatorpkg in the OEM folder that looks to contain the provisioning information and databases. It also includes some Verizon audio files and some PROVXML files for configuration of Verizon.
I don't think there's a way to get a ROM DUMP from a Mango phone yet, is there? If there's a process I could dump the ROM and check for the operatorpkg folder but my guess is that it would be missing on the Mazaa.
Am I naive to assume that copying the operatorpkg from the Trophy (and nothing else from that image) into the ROM image of the Mazaa would essentially make the Mazaa a Verizon-capable phone?
If anyone knows how to dump a dev-unlocked Mango phone's ROM please advise.
Another HTC Mazaa Request
I too have a "developer" HTC Mazaa, version 7661.wp7_5_trial(mojobld).20110607-1657 and have so far have zero success in activating it on Verizon. It works great as a WiFi device and I want to use it to replace my current phone.
For those who have gotten it to work, PLEASE PROVIDE SPECIFICS. When I take it Verizon and use the IMEI and/or MEID, it "provisions", but as a "test" device. It can't see the network and still gives three beeps when I call ANY number, including *611 or *228. Further, since it's not a "retail" device they apparently don't know the program sequence (the #-#-something-something number that puts the phone in setup mode), and the sequence code one for the very similar HTC Trophy didn't work.
Is there an HTC Mazaa RUU ROM image out there that someone can point me to? I haven't found one yet.
Also, has anyone figured out the HTC Connection and HTC Hub apps to work? HTC Hub says "attention required" and won't uninstall nor install. Also, HTC Connection Setup warns "there is no SIM card" even though it's supposed to work on both CDMA networks (w/o SIM).
Again, please provide SPECIFICS if you can help, (or at this point even "hunches" would be OK --LOL) or if you can direct me to a source who can, I'd appreciate it.
cdma phone
I contacted the person at Microsoft who arranged getting me the dev phone and they swapped it with one that works on Verizon. Just did a "switch device" on their web page and it works great!
Next Issue
So I have the Verizon enabled Mazaa and it works great, EXCEPT I can't send or receive media via SMS. Everything says I need to run HTC Connection Setup, but I can't because it tells me I have no SIM card!
Apparently Connection Setup configures everything needed to do what I'm after, but I can't run it.
Anyone have any ideas?

Wow. You actually got it to work on Verizon? How? Please provide the details. I originally gave up on getting mine provisioned on Verizon and went to Tmobile where it worked like a charm. The problem is, there's NO Tmobile reception in my office complex so I've got to go back to Verizon, with this or another phone. The more details you can provide, the better. Feel free to PM me.
There is an FFU file posted in another thread that may provision the device on Verizon for you. MS sends the device out provisioned for either GSM or CDMA. They didn't provide a method of changing the configuration on our own.
So, to get it on Verizon, you can either contact MS and send it back to be flashed with the CDMA image, or you can try flashing the FFU that was posted here. Mine was originally provisioned for Verizon, but to get Mango I had to flash the FFU - so I am successfully using that same FFU image on Verizon.
Be warned that MMS & 3G don't work on Verizon (SMS does, though). I also get occassional crashes on my Mazaa.

[Q] No Internet sharing on unlocked ATT devices???

I'm hoping this will be figured out since it's a major feature that will never get to be used.
I for one am using the ATT Titan unlocked and on a different carrier (Telus) and yet when switching it on it still asks me to contact ATT or dial 611 to use tethering.
I highly doubt calling ATT from Canada will allow me to use this feature. I also doubt Telus (who doesn't support non Telus phones) will be able to help me either. I also doubt HTC can do anything.
There has to be a workaround for this.
I have got the same problem using an AT&T Samsung Focus S on Rogers. there seem to be no way to remove this unless you get it dev unlocked and play with the settings.
but even that is impossible now since Chevron Unlock has been down for a while now.
its actually a feature i used almost everyday. im gonna give it a few days, if there is still no solution, im going back to my galaxy s2. as much as i hate android, at least when you pay 500$ for a phone, you can what u want with it.
I would think that for HTC devices, that you could use the HTC Connection Setup app to configure your device for your carrier and that should point it in the right direction.
Most other manufacturer's provide a similar tool for their phones and I would assume using those tools would also configure your device to work specifically on other carriers.
Otherwise, it would be something that you'd have to contact HTC/Samsung/LG to see if they can provide a tool or fix to configure your device properly.
I doubt they would help since they sell devices to carriers, they will tell you to contact carriers. I downloaded the Samsung Wireless manager but even though i use Rogers APN, it seems stuck on AT&T APN for the Internet connection sharing.
aside from this issue i really liked the phone, too bad !
I have the same thing on my HTC titan from at&t - amazing phone but the tethering is a bummer --> starting to think I should have got the HTC ultimate from Brazil - it has the same bands as the at&t one but doesn't have any of the carrier branding on it.
I'm going to give it some time - once interop unlock is available im sure someone will find a way around the at&t lockout - or at the very least we should be able to flash the Brazil rom onto our phones
My Surround didn't even get 7740...

Prepaid

Can this phone be used on the 65.00 plan for ATT? Also do I need a sim in the phone for wifi too if I just wanted to use for wifi and no plan? Im new with this phone

I think this forum (One X AT&T) is what you were seeking: http://forum.xda-developers.com/forumdisplay.php?f=1572
Also this one for (One X+ AT&T *better than the International one*) http://forum.xda-developers.com/forumdisplay.php?f=1816
You are currently asking this question in HTC One X (Tegra3/International) forum.
Regardless of which phone you are interested in, you can always use your phone without a SIM card (in Android).
However, I won't recommend you to buy the Int. version; you will almost get no support from AT&T, and they will try to make it an excuse and sneak their way out from helping you. Beside that, you won't have an access to 3G network on AT&T (you will be left with only 2G, in other news that would be dropped in 2017).

[Q] Supercid carrier firmware swap m8 verizon to att

I have terrible reception and no MMS on an unlocked Verizon m8 swapped to AT&T sim. Phone is unlocked via sunshine with TWRP custom recovery and flashed to the latest Verizon firmware via http://forum.xda-developers.com/showthread.php?t=2723159 running Viperone 3.1.0 and I believe some kind of faux boot. Can I switch to AT&T firmware to get the best reception from this phone. So far I have read the hardware is all the same and was thinking I could open up the AT&T bands with this new firmware. Is there a better firmware? Can this be done on a Verizon phone? Any advice would be appreciated because I don't want to brick it and would be better safe then sorry.
If your phone does not support the at&t bands, there is likely nothing you can do about that. Also check you APN settings in phone settings, mobile networks. If they are wrong or missing, you won't be able to use data. You can google the settings for your carrier.
Good luck!

APN settings are fine have tried all of them I believe. Was wondering if I change the firmware for the phone and turn it into an AT&T phone and replace the ROM again with the Viperone ROM if that would free up the bands if the hardware is the same. If the hardware for the Verizon phone is different from the AT&T phone then I'm stuck but I'm hoping they released 1 phone with the same hardware and just put different firmwares on it so i can change the radio firmware etc.

Are u running the att viperone version or the Verizon version? I have a vzw branded m8. Running viperone. But I run the T-Mobile version so that I have a bit better call quality and I do receive all my sms mms and most my 4g antennaes. My only gripe is going between towers with 4glte on, it doesn't travel very well between towers.. So I run on wcdma only and I get my 14 gb data which is fine so that I can travel and get plenty speeds without buying another phone.

I would like to know this also, as I have a verizon m8 and I would like to entertain the idea of putting it on straight talk with at&t service.
Looking to see if anyone can post a copy of a build.prop from a verizon m8 with working att mms. I have edited mine and still nothing. Used several different text apps and every apn i can think of.

So you tried go sms pro ? That one seems to work one of the best. Also did you try google hangouts since they added support for google voice in to it ? The hangouts is supposed to work off wifi also so that could help you when on wifi at least. Did you check the at&t m8 forum for this conversion I saw another member thought they posted the conversion in the at&t forum for the m8. I have not had the time to look for myself yet.

[Q] Verizon HTC one M8 to Ting GSM (Sprint)

Hi XDA!,
Backstory:
I have an HTC one m8 previously on verizon. I just unlocked, s-off, and flashed a lollipop ROM to it in hopes it would get rid of the locked APN settings verizon sets on their devices. This was a success, and was necessary in order for me to use this device on Ting's new GSM service. Now that I have an unlocked phone and my Ting GSM SIM, I am having connectivity issues. Everything works, just very very spotty. At my desk it will fluctuate from zero service to full LTE. I was suggested to flash a new baseband version from a redditor when google lead me to this forum.
I have done only a few days worth of research so I am no way knowledgeable on how to proceed from here or if this is even the correct solution for my problem.
Here is some information on my phone and thank you to anyone who replies.
