[Motorola Droid RAZR] Quantumstate:
Nobody's ever going to make it to MIUI if they can't overwrite GB with ICS. There are -no- instructions, and I must be the only one trying to do this these days.

Well I've found the Linux method, and downloaded the script. Put the script and fastboot file into the fastboot EU image directory and ran it. Every single file came up with "Preflash validation failure". I searched around and found that the version of fastboot that comes in that archive is old and cannot handle large images, so you have to get this one:

Well this worked better for me, but could only write a couple of files successfully. The rest still failed with "Preflash validation failure".

When I reboot the phone it crashes now and goes to fastboot mode, I'm sure because I now have a mix of files on it. And I am fairly confident now that the 'Preflash validation failures' are because I am trying to flash an EU image on a NA phone.

But there are no images labeled for the US. There are images for Mexico, and Canada, but the Canadian image failed with I tried it in RSD 3.7.

Edit: Yup that was it. These things are signed by region. I got those errors because the Canadian existing images don't match the EU ones I was trying to flash. You have to flash an image from the same region you are in. I was able to flash the Rogers Canada image here completely using the fastboot for large images from Motorola. (link above) Now the phone boots again, although I am still at 2.3.6. I have to decrypt the long filenames of the images to try and discern the version numbers, FCS.

So now I have to find a fastboot ICS image for my region. Once I flash -that-, then I can flash BootMenu Manager, which I can hopefully use to install MIUI. I doubt that very few people in the world have gotten this far, at least recently.
