About rom flashing on M8 - One (M8) Q&A, Help & Troubleshooting

HI,
I own a Galaxy s4, being tired of samsung and wanting a change I was looking on the M8.
I have a question, if I buy the att variant, will i be able to flash International versions roms, or google edition firmwares?
Is this posible or are they not compatible.

Are custom roms compatible with the I257m?

Being Canadian not getting the international phone can any one tell me if the international Roms will work with the Canadian s4 mini? I know it's very similar to the us model but that one has a locked
Bootloader if I am not mistaken.and the Canadian model is not locked.
I know the 6.3 mega has compatibility between Canadian and international models, (and very similar hardware to the s4mini) so I was hoping if someone had tried the s4mini international Roms on their I257m and had any luck.

[Q] Can the s4 mini (AT&T) use custom roms?

Hi all, I have an s3 mini under AT&T that I wanted to install cyanogenmod on last night. After lots of searching I found out the bootloader is locked and no one has been able to unlock it, therefore I can't do any custom roms.
Does anyone know if the same problem exists with the s4 mini? I'd upgrade to it if I can install a custom rom.
I searched around and saw something about s4 mini international, but I doubt that's the same as the one I'll get from AT&T, right?
thanks in advance

ROM/Kernel Compatibility - Please help!

Hello guys! I'm thinking of buying a Harman Kardon SIM unlocked M8, but I've one serious question.
Is every ROM/Kernel cross flashable? Can I flash everything here (http://forum.xda-developers.com/htc-one-m8/development) on it?
Sorry for the noob question, but please help me!
Harmon Kardon edition is Sprint, which is a US carrier with a CDMA network. Unless your local carrier is CDMA-based, I would not advise buying this version. The HK edition is known as a "CDMA" variant (along with the Verizon version). Yes, it does include some GSM support (mainly for Sprint customers while travelling abroad) but its different hardware from just about every other M8 version (which are known as "GSM" versions of the M8).
For the HK edition, you should only flash ROMs specifically intended for the Sprint variant. And that is part of the reason I would not recommend buying this version. Your choice or ROMs would be more limited, and you are better off with a "GSM" M8. Also, radios are interchangeable on the GSM versions, but can't be flashed to the CDMA variants. Meaning for the most part, band compatibility is set on the CDMA version, while on the GSM version, you can flash radios from other carriers and change band compatibility (if you need to do so to get service on your local carrier).
The HK audio mod can be flashed to just about any other M8 version, its just a software mod. So the only desirable thing (if you are not on a CDMA carrier) about the HK edition would be if you like the color scheme, or the HK earbuds.
And no, ROMs and kernels are not all cross-compatible. Sense kernels only work on Sense ROMs, AOSP kernels on AOSP ROMs, etc. Also, you can't mix a KitKat ROM with a Lollipop kernel, and so on. When in doubt, read the kernel thread to check for details.

Sprint M8 to stock M8

hi there
i have an htc M8 Sprint Device (831C) and i want to change it to a normal stock M8.
I'm in Turkey, I've bought the phone from outside of the country and i can't use some features like wifi hotspot because of the devise is unlocked version. in other words, i want to get rid of Sprint M8 rom.
Is there any way to do this? ıf its possible, how?

Your best bet is probably to unlock the bootloader, and load a custom ROM (that specifically supports the Sprint variant), rather than a "stock" M8 ROM.
Reason being, the Sprint version is a CDMA (includes both GSM and CDMA radios) and actually different hardware from the other "GSM" phones (that you are calling "stock"). Trying to "convert" your Sprint version (installing "international" firmware, radios, etc.) is a very bad idea, as it probably won't work, and might even brick the phone.
Quite frankly, you probably bought the wrong variant for your country/region. Just about any version except Sprint/Verizon would have been better, and could be converted to be the "international" version.
oh got it. i think the custom rom is my only chance. thank you for your interest...

Sadly, No
AT&T use locked bootloader which means you can only flash official AT&T signed firmware
Also there's currently no way to flash custom ROM on the AT&T Note 5 so you (we) are at the mercy of AT&T
The only hope is one of the senior XDA developers finds a way to unlock the bootloader then we will be able to flash custom ROMs and get Nougat 7.x that way
Thanks for the reply, I'm happy to wait, I know the Asian versions of the note 5 are getting the android 7 nougat update this December, my question is Will the at&t ever get the update
