[Q] China 4G-LTE - Droid RAZR M Q&A, Help & Troubleshooting

How to modify the baseband of RAZR M meets 4G-LTE of China

You cannot, I guess. Hardware limitations that no software will be able to work around.
As far as I know only a handful of US phones support B41 which is one of the bands for TD-LTE. For example the Nexus 5, but it has to support B41 by hardware before we are able to unlock it. As for RAZR M, it doesn't even have B41 support by hardware.
You Chinese dude? 你好

[Q] Support for Galaxy S 4 (i9505 + Carriers)?

Hello, will this eventually officially support the Galaxy S 4?
Even though there are many versions of the S4 (carriers, international), we could flash ROMs from other devices' forums (IE, my T-Mo S4 can flash ROMs from i9505 international (but still needs a kernel optimized for T-Mo version).
Edit: wrong thread sorry

[Q] Update Radio

Im currently runing on the 4.2.2 basesband (M9615A-CEFWMAZM-2.0.1700.48) to flash a 4.3 rom do i have to update the Newest baseband ????
I had some issues trying to keep an older radio when I first moved to 4.3, I only held onto it for lte purposes but I found some awesome hybrid radios that worked flawless.
Search out the radio thread and grab the latest hybrid, works great if you want to have lte enabled with some of the newest ROMs (that may not support lte out of the box)
And be sure to thank the dev that created them

would the hybrid radio work on Paranoidandroid ?? cause it asks for you to be on the latest radio
Yes it should work, there are a couple hybrids of the latest ones, again not needed if you don't use lte, but if you do they're great!

You need to flash a hybrid radio unless you never updated past stock 4.2.1,
newer radioes have the code disabled since it hasnt been approved by the FCC for LTE

The Nexus 4 does not support all of the AT&T LTE bands. It lacks the most commonly used LTE bands for AT&T and therefore can only be used in a couple of cities. If you do live in one of those cities, you need to unlock the bootloader and flash a hybrid radio.
OK I've been reading and I'm a little confused is there a solid working root and bootloader unlock for 4.4.2 ?

You can flash any baseband (aka radio) you want but, in order for LTE to work, you will need to flash a hybrid radio. For 4.4.2, you would need radio version .98 or .97
There was a recently released app that makes installing or changing either the hybrid or stock radios extremely easy. I used to use the manual method until this came along:

As was also mentioned, AT&T Band 4 is not available in too many areas, so don't be surprised if you never get LTE.
