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

Ok, so I picked up the new Telus Defy with the 850/1900 3g band for use with AT&T and it works great with 3g speeds better than I was getting with my Atrix.
So far, I've installed MIUI and OCed it and am pretty happy with the phone, but am hesitant to really start playing with it as I can't seem to find a Telus OE SBF - anyone have one?
Also, can someone tell me if the baseband changer included with CM7 be able to retain the 850/1900 3g bands?
Thanks guys!
if you got the original ROM running right now, grab the baseband, zip it, post it here, and I do a compare to tell you if it's included or not. You need to copy this folder: /system/etc/motorola/bp_nvm_default
If its a new one I would like to include it in the Basebandswitcher.
These US Basebands are included in the Basebandswitcher:
US T-Mobile 3.4.2-107-4 Frequency Bands: 850/1700/2100MHz
US T-Mobile 3.4.2-107-9 Frequency Bands: 850/1700/2100MHz
US T-Mobile 6.xx.0 Frequency Bands: 850/1700/2100MHz

Didn't realize that the baseband was just a folder under system - thought it was a separately flashed partition.
Anyways, here is a copy of the Baseband that came with the Canadian Telus Defy 850/1900.
Let us know how it compares to what you already have in the switcher!
I'll post back here, thanks for the Baseband. Can you post some infos about the ROM you currently use? A screenshot from the telefoninfo for example?
Does the baseband also rely on the firmware that was flashed to the phone?
Anotherwords, if you flash an sbf for a 900/2100 market to a phone with the 850/1900 bands, can you just use the baseband switcher and select the 850/1900 bands, or do you also need to flash the corresponding baseband partition?

There's no spezial parition for the basebands. When you select a baseband for your region/contry/provider you'll be fine no matter what you flashed before
Having a little trouble here with the baseband:
Started with an unlocked Telus Defy (850/1900). With the stock firmware and on the ATT network I was getting great up/down speeds - better than with my ATT Atrix.
After making a backup, I flashed NORDIC and CM7, and using the baseband switcher built it, I now get (relatively) slow Internet connectivity regardless if I use TMobile (850/2100) or Argentina (850/1900).
So I tried copying the bp_nvm_default folder from my original Telus backup to the phone running CM7, but now get no service! Is there an additional setting I need to change? Maybe one of the dbs? I'd really like to get the Telus baseband working with CM7!!!
I have a wcdma 900/2100 one and flashed T-Mobile rom, and no way to connect to T-Mobile or any hspa provider in north america
Does anyone know if its at all possible to build a mod that can enable the GSM Radio for the Verizon SGS3? As of now only the CDMA and LTE radios are enabled, but Verizon plans to enable global roaming "in a future update". Seeing as how i'll be going oversees in 2 weeks I'd like to know if any of you talented devs has thought about creating a script or mod to enable global GSM roaming?
enable GSM radio on vz sgs3
Someone should correct me if I'm wrong, but I believe adding GSM support would require 2 things:
1) support in the modem software (I don't think we have the source for this right now)
2) support in the kernel (I also don't think we have the source for this either)
I think we are at the mercy of VZW's release schedule for global roaming until we can solve our bootloader issues and get source (which may never happen).
Right now, InvisibleK and other devs are devoting a lot of resources to flashing a custom bootloader. So far, they've been able to flash a custom boot.img to the recovery partition (including an insecure kernel). A potential downfall is that we loose our recovery partition in the process. They've been able to overwrite the bootloader but there is another check somewhere else. Perhaps a HW check in the snapdragon s4 (qualcomm secureboot)?

I have noticed GSM settings and international settings as well on sprint's version. I wonder if they plan on doing the same thing..
I'll be following this thread.

hmm interesting.. so if we ever get an unlocked bootloader it should be it do-able?

has anyone been working on this?

i guess not =( would be nice ya know for sprint to be able to work with gsm.
not sure they have the slot for the sim though.
If Verizon plans on adding support then maybe all it needs is an unlock. Anyone with an unlocked verizon gs3 try a GSM sim?

Mike Reid, developer of Spirit Radio app, has been working a lot on this. He states the problem is with the LTE radio in the North American version. http://forum.xda-developers.com/showthread.php?t=1732685
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
So basically as the title states, can you flash a tmobile rom on the Verizon s3? i got my tmobile sim to work, and id like to use the tmobile software as well. Can it be done? if so, what ported roms are available?

I wouldn't. Even though it's the same device basically it will cause issues. Only flash specifically for a universal d2 or d2vzw

Ok so i have a G955U Verizon unlocked S8+. I want to use it on AT&T but i was told that verizon had disabled a few of the AT&T bands. I dont care about rooting, but if i could root and get all the AT&T bands and no bloat ware that would be above and beyond. I would mostly be happy with just having the capability to use all the bands. So i saw PartCyborgRom had a custom rom that has just recently been updated to work with the v3 BL. Would this rom give me access to all of my AT&T bands? Sorry im a newb haha 15+ year forum creeper, first time poster. Need some help guys this new stuff is over my head! Cheers and thanks!
EDIT: So i have found bboii86's thread on the AT&T S8+ Stock Oreo G955USQU3CRD4 Odin files: https://forum.xda-developers.com/at...g955u-stock-g955usqu3crd4-odin-files-t3789751 and because im already running the same baseband version somehow but with Verizon bloatware im going to try flashing it. I suppose having the AT&T bloatware rather than verizon would just make me feel better lol. So new question with parts of the old still in place: will running PartCyborgRom give me access to all the bands on the AT&T network and will I be able to use it being on the 8.0 (oreo) Android Version? Much appreciated my friends.
