Hello guys,
Been searching for some direct answers, but I would like some input regarding ROM's that retain the U.S. band unlock.
Just picked up a droid 3 and unlocked it successfully, running debloated stock ROM now.
Your input is appreciated
Speaking from no experience here...
I don't think a ROM will mess with the band unlock at all. I'm assuming that you're running it on a GSM network? You'll need to tweak build.prop and change out libmoto_ril.so to get a CDMA ROM working on GSM. IIRC, that's all you need to do.

Hi Everyone -
AT&T finally gave me the unlock code for my Galaxy Note 3 SM-N900A phone. I'd like the move it to T-Mobile, but have some questions before I do:
1. Is there any way to flash the T-Mobile/N900T firmware to an AT&T N900A variant? I'm talking the official factory firmware...CSC, bootloader, radio, everything needed to essentially do a complete conversion. I'm not interested in custom ROMs based on T-Mobile's firmware and that kind of thing. I assume if there is a way, it's not as simple as flashing N900T firmware in ODIN, since it would probably fail the model checks.
2. Is there any way of enabling the 1700 MHz AWS band for HSPA+ on an N900A? I know it works fine on T-Mobile LTE and will also work on HSPA+ in areas where T-Mobile has refarmed it for 1,900 MHz. I assume the 1,700 MHz lockout on the AT&T version is probably a software limitation inside the modem firmware.
If anyone can shed some light on this, I'd appreciate it.
Thanks!

You can't flash them or you would get hard brick. If that were the case people would have already unlocked their BL's using T-Mobile

Figured.

I wonder why it would hard brick though. With the exception of atts bl being locked, wouldn't it all be relatively the same? Would it be possible to clean up the n900T bl to match the n900a?

Make sure you pay attention to the Modificatinator file and add the T-Mobile carrier file after installation. Works fine and much better than stock ATT junk rom.
Quick question to everybody on here... Is it possible to ODIN the baseband/modem for N900A to the N900T? I want to do this because my service provider is Cricket, which is an MVNO of AT&T. It's not a priority, but is it possible?

Probably, and if it doesn't work you can Odin the stock NC2 or NL1 firmwware back and start again with this ROM.
But why? If you're getting LTE the way your phone is (assuming Cricket is giving you LTE), you won't gain anything by flashing a different modem. (Unless you're getting a lot less signal with this ROM than you were with the NC2 or NL1 modems.)
Hello all,
I am about to take the plug in the Moto X world and have a couple questions. I live in the Great White North (i.e. Canada) so the only available version I can easily get my hands on is the Rogers version. My question is will I be able to use it on Rogers if I flash the Developer edition ROM. Will the developer edition ROM even work on a Rogers Moto X?
Thanks and much appreciated!
Yes, it will work fine as long as you have unlocked the bootloader. You will lose band 7 LTE (2600 Mhz) if you use the full developer edition firmware however you can flash the developer edition firmware and then flash just the modem from the Brazil 4.4 release and it will be restored. This is what I have been running for a while now on two Rogers XT1058s and it is working extremely well. Mine are sim unlocked and running on Koodo.
Thanks for the info! Sorry to ask such a noob question but where can I download the Dev edition firmware? I can't seem to find it. Also can you let me know where I can get the Brazil modem?
Much appreciated!!

Just curious, why would you need the dev edition ROM on the Rogers X? It has an unlockable bootloader, is extremely easy to root, and you can remove any extra apps Rogers puts on it? What's the advantage to using the dev edition ROM?

Guys, I have a question for anyone that's SIM unlocked their 920T's. At the moment, my 920T is running xtresolite 2.2. It's based off a 920F firmware. As you know, this is an International version. To further complicate things, I needed to SIM unlock my phone so right now I'm using the MetroPCS COF9 baseband. Every time I switch back to a T-Mobile based ROM, my SIM unlock gets pulled and the phone is relocked back to T-Mobile (has been confirmed in multiple posts on XDA). I'd just stay with xtresolite 2.2 but I have no wifi calling or volte. I'm trying to find a rom for this phone that supports a different carrier sim as well as volte/wifi calling when I switch back to my T-Mobile sim. Is this possible?
All the ROM's I find for the 920T are either locked down T-Mobile ROM's under that development section and the general development section is mostly compatible International variants - but lacking WiFi calling or VoLTE. I'm beginning to think these two things just can't work together on the same ROM.
Thanks so much in advanced for a reply!

If you want unlock while on T-Mobile rom. See here: http://forum.xda-developers.com/tmobile-galaxy-s6-edge/general/sim-unlock-t3186826/post62512066
Other than that, not sure about WIFI Calling etc
Hello I have a verizon note 4 and am using it on tmobile my question is this, Now that the 910v can be rooted what happens if I root it and download a tmobile rom and install it on the phone? Will it work or will it brick the phone? I have no idea if there is any real difference between the verizon note and the tmobile note besides the carrier. Any input would be appreciated as I cant stand the verizon bloatware and would love to have my tmobile stuff back
thanks in advance
As far I know not possible
Tmobile is GSM model and verizon is CDMA frequency bands different.
I did something similar with AT&T G2 and loaded a Tmobile ROM on it. First you need root and TWRP or equivalent. and then some developer have to created a modified bootstack that are tailored for your phone model to work with the rom. Once you load the bootstack, then you load the rom without the radio. Not for the faint of heart.
Hello
I have a K3 note, version K50-t3s, running Android 5.1
I'm planning to flash it to Android 6 (haven't decided which ROM. I was thinkig of Ghost, but if anyone has any recommendations, let me know). It currently works with 4G FDD with both SIM slots, and I need to keep this function.
I read on a French forum that you need to change the IMEI after flashing so that it will work on 4G, but I haven't found any explanation of why that should be.
So, do you really need to change the IMEI, and if so, why?
Thanks.
