[Q] Carrier conversion question - Verizon HTC One (M8)

I live outside of US.I saw this Covert HTC One M8 Verizon to Fully Compatible T-Mobile Version thread & i love to do that to my phone.But i have some questions before flashing that.
1.What exactly is this.I mean like flashing a gsm rom of just chaning/modifing network to work better with gsm?
2.If i super CID,then can i flash any varient support rom & select gsm carrier (such as AT&T,T mobile) as my carrier not just for that ARHD rom?
3.Veriozn & gsm nand partitions are different right.So selecting gsm won't do nothing to nand partitions?
Thanks

hi i just bought touch pro 2 from telus and im using it on rogers gsm. i dont like the stock rom cant edit alot from it. was wondering if i can switch everything to strickt gsm radio and rom.
No you can only flash cdma roms to a cdma phone. If you flash a gsm rom you will have a big brick. There are many cdma roms in the below link. http://forum.ppcgeeks.com/forumdisplay.php?f=98

Doesnt matter for customruu...GSM ones work in CDMA.
Have u hard-spl your TP2? Hard-spl is a MUST if u wanna flash custom ROM. If I'm not wrong, T-mobile is GSM version. I use TP2 Sprint which is CDMA/GSM. I use GSM mainly in Indonesia.

If you bought a T-Mobile branded phone it is referred to as a "GSM" version.
You can tell which version you have either by the carrier branding, the model number or a conbination of both.
EVERY SINGLE TOUCH PRO 2 HAS A SIM CARD.
and EVERY SINGLE TOUCH PRO 2 HAS A QUALCOMM CMDA MSM CHIP.
Why? Because "3G" GSM isn't really "GSM." It's WCDMA (otherwise known as UMTS or a HSPA variant). And Qualcomm makes the CPU chip which drives the system.
So what you're seeing is 100% normal. Both the "GSM" and "CDMA" TP2s have Qualcomm CDMA CPUs inside.
thanx

You have to Hard SPL before you can use a custom ROM.

Why does it say everywhere else not to flash a GSM rom on your CDMA device? If both were the same phone, then wouldn't the custom ROMS be shared together and not segregated into a Custom CDMA ROM forum? I know that I can hold a GSM (Tmobile) and a WCDMA (Sprint) Touch Pro 2 side by side, and they are not identical, though they could have the same chipset.
I would double check that information about running custom roms for GSM on CDMA...Every post I see about it, is from people who did it, then think their phone is bricked until they flash a CDMA rom onto it.

ROM for GSM only & CDMA/GSM is different! Including the splash screen is different too. U can't interchange them, could brick ur device. Several people have bricked their TP2 cos wrong ROM. If u wanna plenty of CDMA/GSM custom ROM, just visit www.ppcgeeks.com. This xda-developers mainly on GSM only ROM.

Verizon TP2 Hard spl for running gsm?

Hi, i have purchased a Verizon touch pro2 from the states. It has been shipped here to Australia i have unlocked the GSM and now am running on a gsm network, my issue is does this now change from cdma roms to gsm and vice versa with SPL.
Thanks.
No you only use cdma roms. If you use gsm roms or radio you will create a nice brick.
Great, thanks very much
I have the same phone, using in india successfully over GSM, can anyone suggest me where i can get custom ROM for my Verizon Touch PRO 2? do i require to apply Hard SPL before i flash any ROM? As I can only flash custom CDMA ROM to this device, will GSM keep working as it is even after flashing custom CDMA ROM?
Thanks in Advance
It already has a cdma rom on it because it is a cdma phone. Go to ppcgeeks.com for hard spl info and lots of roms.

I concur a hideous depressing non responsive brick.

Sprint to Verion and vice-versa

Noob question.
Now that we have an unlocked bootloader is the vzw hw so different from the sprint one?
Can we somehow install a custom rom (stock or no) that was designed for the S3 sprint one and vice-versa from vzw to sprint? Without porting.
If not then why?
Good Question, I would like to know this too. (BUMP)

No, you are most likely not going to be able to use a Sprint rom on this phone. They use different radios and most likely a different bootloader.
Also, the LTE frequency for both devices are different and the Sprint version uses the 800, 850 and 1900mhz cdma frequencies wheres the verizon version is only 850 and 1900. The Sprint uses 1900Mhz for 4G as well.
I think the only way this would work would be if a dev made a rom that was specifically for the CDMA version of the phones and would detect which type it was running on before flashing

Need some help please! What stock ROM to use - original carrier or current carrier?

Hi all,
I need to reflash my stock ROM (HTC One M9) after it got bricked. As usual, there are a number of stock ROMs available based on carrier. The phone was originally Rogers when bought, unlocked, then placed on the Virgin Mobile (Bell) network.
Should I flash the Rogers ROM or the Bell ROM?
