Baseband question - RAZR HD Q&A, Help & Troubleshooting

Howdy! I have a friend who has a Verizon Razr Maxx HD. He would like to use it on T-Mobile. I know about the NV RAM bit change that will allow non-Verizon sims.
My question is will flashing the Rogers ROM replace the Baseband firmware and allow 1700/2100Mhz LTE on T-Mobile? I found the specs for the Rogers X925 and it states that the device supports these bands. Thank You in advance!

Bump. Anyone tried this or know if it is safe?

[Q] Will those AT&T, Verizon etc roms work for Canadian G2?

Just saw there are lots of roms on the sub forums for AT&T, Verizon etc.... are those working for Canadian G2?
No. The verizon model is a cdma phone and the att model has a extra noise cancelling mic which causes speaker issues when ported to other gsm models. The canadian version is the same as the international (d802) and tmobile (d801) if i remember correctly. So you should be able to flash a tmobile or d802 rom if you switch out the boot.img with the one from your device. Or flash a custom kernel after the rom install that is r your device.
I know one of the canadian variants shares the model number with tmobile us device, and there is a d803 right? Is the 803 a cdma device?

Verizon M8 LTE Bands

Hi guys.
The Verizon m8 supports these LTE bands : Verizon: 700/AWS/1800/2600 MHz (taken from the official HTC web site),
but it seems like 1800/2600 are software locked and can't be used.
I had the same issue with the AT&T version of the M8, but installing a rom would fix this issue.
Unfortunately, installing a rom on the Verizon m8 does not help and these bands are still locked.
bootloader unlocked and soff.
Any ideas?
Thank you!

Hi, M9guy
I have same issue with you, I am in China Now, they lock 1800MHz. I tried to find solution, but failured, android version for Verizon M8 can use QPST unlock Verizon Band limitation, but M8 for windows not support by QPST. Certainly, I am not expert, so don't know whether exactly support. After check XDA, found have some guys use QPST flash custom image for Lumia 1520, I don't know whether M8 for windows can use QPST.
If can use QPST, we can try to change Band data that should same as android version.
Thanks

Anyone know how to GSM Unlockl the 'Trackfone/Straighttalk SM-S906L version of this?

Hello,
does anyone know the easiest way to GSM unlock the Trackfone/Straighttalk version of this Verizon S6?
This version is called the SM-S906L . Apparently it is identical to the Verizon version except running a different rom for CDMA.
Could I just root it, install TWRP and install a Verizon rom on it.........so it would be GSM unlocked?
Thanks for any info.
