Guys,
let me ask you one thing: Did you read a little through the forum? did you do any searching?
Ok, this is Lumia 900 section, but in the Lumia 800 section, this was discussed a couple of times now... Everyone is asking the same, i bet your answer's already posted anywhere here on xda

But ok then, once more:
To be able to flash a custom rom to your Nokia Lumia 900, 800, 710, you need to have the qualcomm bootloader on your phone.
To get this, you need to follow a nice tutorial for Lumia 710, but for Lumia 800 and Lumia 900 you need a couple more things:

1. You need ATF flasher box
2. You need good soldering skills or the special atf cables from gpg industries

Here's a tutorial to SIM-Unlock a Lumia 800: http://forum.gsmhosting.com/vbb/f609...orial-1564470/
This is almost the same procedure for "bootloader-unlocking" your Lumia 800 and Lumia 900. You just do not need to click SP-Unlock, you need to click "boot repair" (and select qualcomm, of course).

Here's the thread of the special cables: http://forum.xda-developers.com/show....php?t=2112984

So, if you don't want, or can't buy such a box, check for a local phone repair shop in your town/city. If they have ATF, i'm sure they can do this for you for a small amount.

Yeah, good news!
My Lumia 900 arrived today. I'm going to disassemble it now and flash the qualcomm bootloader to it.
Then i'll test my own rom (rm-823)

Very helpful, just curious, do you think this will ever lead to a software based full unlock? Or will we always have to open up the phone to unlock the 900?

I think ATF software version 5.91 or higher allow flash boot without opening phone, if wrong pls correct. Because i read ATF log and found this.

That mode is equivalent to flashing using Care Suite or NSS Pro. It only accepts signed FW images.

The JTAG and UART ports discovered in the SIM slot are more promising, someone should check out if they are actually useful.

I thought it would be as easy as flashing a new rom onto an android phone.

It is actually very easy, once you've got your bootloader unlocked. But doing this, can be a real pain...

is there a faster way of unlocking your bootloader instead of going through this long rigorous process

Of course there is, i'm just only making long difficult solutions, instead of easy ones...
Just kidding.

No there is not. I think it would be very stupid doing this difficult process, if there would be an easier way...
