I obviously know adb won't work on WP8, but is it likely that adb could possibly work on the boot loader only? Anyone have a previous HTC wp such as the 8x to comment?

Great point about even if we were to boot up wp8 we could be stuck with it. A one way trip to window land.

In my non Dev logic it would appear that the only way it maybe possible to go back and forth between wp8 and android would be at the recovery level to some how format the partitions and install via recovery. It was hard.

No

Android uses a fastboot based bootloader, whereas WP uses a EFI bootloader

If someone with a M8 WP wants to post a screenshot of the bootloader (Vol- and Power) then that would help to show that

I'll try to hit up a verizon store to confirm
[HTC One M8 for Windows] ajbiz11:
If they have a non-locked down floor model, you should be able to shut down the phone and hold Vol- and Power

If it says Fastboot ANYWHERE on the screen, then we have a EFI emulator at /boot/

Otherwise, its exactly what I'm expecting: totally different flash, from the OS all the way down to a EFI bootloader

and this is what happened when they tried to use the commands listed:

So it looks like the BL is not the same as the Android specific bootloaders (which is a given). It looks like a windows bootloader on multiple devices for windows phone.

Ideally it looks like we will need a jtag or a ruu leak at this point
[HTC One M8 for Windows] ajbiz11:
It would be almost unheard of, especially as that would literally be a direct copy of what Cotulla wanted to do

The ! Explained:

Press and hold the Volume down and Power buttons at the same time until you feel a vibration (about 10–15 seconds).

When you feel the vibration, immediately press and hold the Volume down button until you see a large exclamation mark.

Once the exclamation mark appears, press the following four buttons in this order: Volume up , Volume down , Power , Volume down . Your phone should now reset and restart itself. (It might take a while for the reset to finish.)
[HTC One M8 for Windows] domineus:
Let's hope.

It could be something simple. But we don't know if the h/w is exactly the same. That's the problem. But this quells one rumor that the BL is exactly the same. It's not!

The rumour never said they had the same bootloader. It said they were cross-compatible, meaning the Windows BL would work on the android M8 and vice versa
[HTC One M8 for Windows] ajbiz11:
Well

I hope to have this work on any phone we can

So

If we get this dumped, then we have VZW radios...so what? the bootloader should be the same between the VZW and ATT and UL versions

We need to be able to switch between them before we can do anything

Edit: Switch bootloaders between Android and WP, to clarify

For those of you wondering about ATT LTE on the VZW version, it doesn't work. I put the sim from my 1520 in, and it said H+. I was able to get texts, but sending didnt work, and i could browse the web and make calls. I didn't spend that much time trying, and i ended up porting over to VZW (I was already wanting to do so, but this phone made me take the jump). I have XLTE where I live anyway, so its worth it.

While I agree, these should be removed from the store, Android suffered from a similar problem in the past. Google fixed it eventually, but only after it was brought to their attention.

Microsoft will fix it it permanently. They have already removed a lot of the offenders. For the record, this was mostly present in the Windows store, not the Windows Phone store.

Not only need ROM to look the hole to make MAGLDR to boot but we need

1.how they build rom ? in WM we knew they building by PB but WP8 who knows ?

2.where can find sources and where to get it ?

3.we need mamaich to make tool , we need bepe to make kitchen

If we want M8/W8 replace HD2 without this will be very hard to make it happen that's why in M7 Cotulla make for WinRT

bepe been missing few years can't find him , mamaich got kids busy at home/work , Buzzlightyear became grandfather also besy with family , Cotilla also missing a year , me also stop doing this for a year , we need bring back 5 of them and others 3 team members to work together on this project otherwide hard to do , after WP7 we don't had any sources that I real don't know how to do this .

About "Bounty" our team not looking for this just play for fun but in the pass how many bounty ? after our team made it happen and how much we got bounty ? in the pass all devices bought by me for whole team but now I can't pay it , I got pay cut 40% last two years.

just my 2 cents
[HTC One M8 for Windows] oryan_dunn:
I doubt this will ever work. WP8 uses EFI secure boot and all pieces are signed by MS along the way. At most, you'll be able to convert an M8 to W8, likely won't be able to go back. Dual boot is out of the question.
[HTC One M8 for Windows] EMINENT1:
In the past, not a lot of interest was found in the platform. Now that it has matured along with excellent hardware, it's wanted even more. I can understand back then if it was just for fun, now it's a bit more serious and there are people that need this to happen. Myself included. I've already posted I will help with donations and i'm sure as these devices get on other carriers as rumored, the demand will rise even more.
[HTC One M8 for Windows] ultrashot:
1) WPAK/so on? Just renamed PB.

3) Well, kitchen isn't a problem - I have generally working kitchen for a year already but don't have time to finish it. WP8 cooking is much easier in general.

I use mine on T-Mobile, only without MMS.

It is known that Verizon has removed the option to edit the MMS APN, as of now there is no way to edit.

As for the DNS errors I was having the same problem, solved it by hard resetting the phone. At setup connect to WiFi and set up your live AFC. Skip the Verizon setup. After the phone is up and running go in to the sim settings and manually set it to T-Mobile; then set your internet apn(fast.T-Mobile.com) . it is very important to manually we it to t-mobile. Then power off and back on, turn off WiFi and test It.

I don't know what reviews you looking at but the CNET review has it listed as 21 hours compared to 14 for the android version.
[HTC One M8 for Windows] md1008:
It only makes sense wp8 is more battery efficient. Wp8 is much lighter with less stuff running in the background, sub par multitasking (compared to android). Its cool android can multitask and run a bunch of stuff in the background which makes it a positive experience but that comes at the cost of battery life.

Besides that's irrelevant even if wp8 was worst than android the point is to try and dual boot or at the very least boot up wp8 not to discuss which has better battery life

This thread is more or less a discussion on converting an android m8 to a windows one and vise versa. Not discussing the differences in battery life, or other key differences in the software. Those discussions lead to flame wars.

Here's to better battery life....dual booting is a great way to find that out. Wish I got the 64gb version for dual booting
[HTC One M8 for Windows] SolarTrans:
No 64GB M8 my friend. Only the M7. They lowered the internal storage because they added a MicroSD slot.

Besides, MicroSD is the only way a dual boot would be possible. I wasn't an Android guy in the HD2 days, but IIRC for dual boot you had to have the second OS running on MicroSD—at least with WP.

May be wrong about that second bit, but I'm pretty sure ;)
[HTC One M8 for Windows] NJGSII:
That and we need a bootloader on the device that would be able to boot either OS. I had something like this on an old laptop of mine. Dual boot would be the most ideal solution obviously as I for sure don't want to give up the capability of running android on this device entirely.

Inside the zip is a CRC file and an NBH. I know zips can be flashed via hboot by renaming the zip to 0P6BIMG.zip and placing on the root of external SD, I think you can extract the NBH and rename it to 0P6BIMG.nbh and place on root of sd and it should attempt to flash it. S-OFF/SuperCID is needed to flash of course.
[HTC One M8 for Windows] Oditius:
S-OFF huh? Another $25 to spend. :( Oh well I downloaded it, will have to think about it. Being Chinese means nothing will be in English? I guess if I screw it up I could always use the RUU I have to AT&T to restore it..... Will think about it a while.....:rolleyes:
[HTC One M8 for Windows] gamer765:
The fact it originated in a chinese forum should mean nothing. This is a Verizon WWE build and AFAIK, Verizon is in the USA only, so I'm fairly certain the ROM is in English. As you guessed, if you screw up, since you're S-OFF, you can always RUU back to AT&T.
