first few partitions are the radio side of the phone. you can avoid flashing it by removing the files from the image directory and it will skip flashing those parts.
It would be splendid to have your adventures in this area documented for the general good.
This 'recovery' is intended for fixing screwed-up phones.
As long as the hardware is OK (including the power and volume switches) then this is a really simple
way to load a complex set
of custom firmware -- or to return to stock.
And - especially if you can load the sdcard /image folder with a computer card reader - you can bring a phone back from very close to death's door.
But it MUST be emphasised that the MD5 must be checked
If people don't know how to do that, then they should be kept away from this method.
The Japanese 003z and the Chinese V880 (and X880?) are well-known have a slightly different hardware setup.
Obviously this is NOT recommended for them.
Those apart, its great for delivery of 'production' rom packages.
If your model of the Blade is known to run 'standard Blade mods' (like standard Clockwork and all the custom roms here so far) then it should be safe, if used sensibly.
But I'd still suggest that any NEW 'BLADE' versions/offerings be checked for compatibility with 'traditional' mods before loading a TPT.
But once someone has confirmed that that version is a 'standard Blade' and not an 003z/V880 (or something entirely new), then TPT is a great way to go for 'production'.
And IMHO, the only people that need to be steered away are those who don't know how to (or can't be bothered to) check MD5's, the owners of Japanese- and Chinese-market phones, and anyone with a new (not previously seen) version.
During development, the alpha and beta stages, using update zips as patches is a much more economical use of bandwidth ...
