Hi, maybe a rookie question, but what exactly is the difference between the z710a, and z710e, aside from the likely A(merica) E(urope)
and if that's the case, what hardware differences exist?
Different 3G bands.
I have a TMOUS Sensation 4G (uses the 1700/2100 frequency) and was wondering if I could flash a Bell Mobility ROM or any other carrier that uses the 900/2100 frequency ROM onto it. Would there be any possible issues due to this?
I believe you need to root the phone first. There's a how to in the Sensation for noobs..I think you'll brick it if you don't.
Forgive me if this is a trivial question, but since European carriers such as Vodafone and O2 Germany also have the dual-core version of the HOX, is it possible to flash a european radio and use the European LTE frequencies? Or are the frequency bands hard-coded into the chipset?
It was my assumption that the US and European LTE variants used the same hardware components, but were just set up to use different LTE bands.
Frequency support is set in hardware.

Thinking more about this, I'm still not convinced it's impossible to flash a european radio on the HOX to swap LTE bands. Unless the physical antenna is different, I'd think that it's a possibility.
With my other phone, the Samsung Skyrocket, we can flash T-Mobile radios to gain support for the 1700 AWS band. The chipset supports it, and it just took a radio flash to activate it. AFAIK, you can't use 1700 and LTE though - that or a radio with support for both doesn't exist.
I guess it depends on what chipset the German One XL uses..but I'll wait to see if someone has luck before I risk my own One X.
The hardware is different, as I already said.
The Skyrocket (and a few other AT&T phones, like the Galaxy Note) included the AWS band in hardware (likely due to the now defunct merger with T-Mobile that was going on at the time). The hardware was there, but AWS was simply not enabled in software. Hacks to make AWS work on these phones just enabled the software side for what is already supported in hardware. Without the hardware already being there, no amount of radio flashing will create support for frequencies not already there.
Its possible that some bands are "hidden" in the same way that AWS was for the Skyrocket. Lots of folks here on T-Mobile are hoping the same AWS support is possible on our phone. But if the hardware is not already there (such as for different LTE bands, as you are asking for), you can't make it happen by flashing radios. In the case of AWS, AT&T had a reason for including support (T-Mobile merger). They don't have a reason for including support for LTE bands willy-nilly, just for the sake of doing so, without any tangible (monetary) reason.
I know the verizon and sprint m8s has CDMA functionality and other versions are GSM only.
Is this an actual hardware difference? Or is it available in all versions but locked away behind firmware similar to how the different carriers lock away different LTE bands?
Thanks,

Might be a silly question but aren't devices that are the same made the same with the same hardware? Like is it made specifically for each carrier? They made 10 different version with different chips and whatnot for that carrier? what's making me not flash Sprint bootloader/recovery/Rom to a Verizon phone of the same device. Couldn't we just hack it to spoof to make it think its a Sprint phone? Im confused on why they would do such a thing, and maybe yes GSM/CDMA phones are different but i mean GSM to GSM /CDMA to CDMA. whats the deal?
