Flashing gpe firmware.. - One (M8) Q&A, Help & Troubleshooting

If I flash the gpe firmware, so I can use skydragon without bugs, is it just a case of reflashing sense firmware to get back to sense ?
I know partitions are changed when flashing gpe firmware, so I just want to be sure that EVERYTHING is changed back when flashing back to sense.

[Q] Switching between AOSP, Sense and GPE question

Hi, just a question that I couldn't quite find the answer to.
Is it safe for me to switch between AOSP, GPE and Sense ROMs if I'm S-On with unlocked bootloader? I remember reading before that you can convert to GPE RUU which adjusts the partitions but you need to be S-Off to do that and just flashing a GPE ROM wouldn't do it (and I can't remember/find where I read it from). I'm not so sure about flashing AOSP (interested cause of the new BMFR ROM by mrjaydee) and switching back to a Sense/stock ROM later on.
Basically, can I switch to an AOSP ROM and then back to a Sense ROM without issue?
Details:
S-On, Unlocked Bootloader
Stock -> ARHD 11.1 -> Sinless 3.6.0 -> Elix-R 1.2.1 -> Elix-R 1.2.2
You're good as long as you don't convert to GPE. Flashing the GPE roms are fine but full converting is what you don't wanna do in your case. Just flash the sense/aosp/GPE roms normally.

GPE Firmware question

If I flash a GPE firmware on a sense firmware, I'll have to format data partitions and then install a gpe rom?
Well you don't have to do a gpe conversions to use some gpe Roms you'll find in the forums. I think skydragon can be used with HTC partitions and GPE converted phones.
It works on gpe but you have to update firmware,sense firmware you just treat it like a normal ROM

moving to gpe or asop from sense s-on

looking to move over to either asop or gpe from sense im s-on with latest firmware can i just flash as normal either of these rom types or will i need to adjust to a different firmware ?
You can flash the roms, but to actually covert to GPE, you'll need to be s-off.
You also need the latest firmware for most up to date roms. ?
The M8 will need to be updated to the new 5.0.1 firmware to use latest Sense ROMS,
for AOSP you can use any firmware 3.x and up.
On the GPE Firmware you will need S-OFF as the change in partitions are locked in
S-ON.

Huh... There is a GPE rom on the sprint forum. When I was s-on I flash the rom then flash the kernel in fastboot. I was on latest firmware but not sure if that had something to do
Yeah, there might be a ROM but the full conversion to GPe requires S-OFF
You can use the GPE Rom Easily, without S-OFF it's like any other AOSP ROM.
But if you want to fully convert it to a GPE Edition, you'll need S-OFF.
The problem with the GPE ROMs/Conversion is that
the HTC File Manager cannot load SD Card Tab (You can't modify anything in the SDCard without rooting it after wards).
And the HTC Camera no longer works on GPE , it used to work before without root.
I guess HTC Ruined the Non-Sense variants again.

Possible to install android revolution over gpe rom?

So I have an m8 with a gpe rom on it, and I want to switch to android revolution, but I remember seeing somewhere that the partitions (or something of that nature) are different.. So I'm trying to find the right flashing process to get this back to flat stock so I can install Android Revolution or, better yet, get AR on the phone without having to wipe my user data.

It depend on whether you did a full conversion by RUU to GPE; or just flashed the GPE ROM.
If you did do a full conversion, you need to convert back to Sense (to re-partition to the Sense partition scheme, as you touched upon).
If you just flashed the GPE ROM, you can just flash the ARHD ROM.

HTC one m8 Skydragon Rom stuck on boot

Hi I just tried to flash Skydragon 4.0 on my bootloader unlocked, supercided with S-OFF one m8 running latest MM GPe firmware. The installation completed successfully but it gets stuck on the Google splash screen.
Does anyone know why this is? Do I need to be rooted? My recovery is TWRP 3.0.2
You shouldn't install any Sense based ROM on GPE firmware, won't work.
Sense based ROM requires Sense firmware. GPE system partition is too small for Sense based ROM.
When I tried flashing the Skydragon sense based firmware TWRP couldn't mount my internal storage, cache, system or data. Do I need an earlier version of TWRP or is it something else that's causing it?
I don't really understand what you're trying to say.
There is no Skydragon sense based firmware, only Skydragon sense based ROM.
Firmware and ROM are two different thing.
Are you saying you tried to install firmware.zip with TWRP ?
If yes .. this is wrong. You can't install firmware.zip with TWRP, you only fastboot flash it or use microsSD method.
Now you still have google splash screen when trying to boot ?
If yes, you still have wrong firmware problem.
Post your fastboot getvar all result without serial & imei no.

As ckpv5 pointed out, firmware and ROM aren't the same thing. Firmware refers to hboot, radio, etc. that is separate from the ROM. Firmware is not installed in TWRP.
Did you convert to GPE using s-off and RUU; or just flashed a GPE based ROM?
Is your bootloader screen black or white?
Also, post the getvar info as directed by ckpv5 above.
I flashed the GPe firmware using fastboot and then flashed the GPe ROM using TWRP. Bootloader screen is black. I will post the getvar data.

As mentioned before you can't install a Sense based ROM on GPE firmware.
If you really want to install a Sense based ROM, you need to convert your device from GPE back to Sense.
This means you need to flash Sense firmware using fastboot, format data to get back the correct Sense partition then only you can install Sense ROM.
Thanks! I got it working
