ramjet, I'm assuming that method is for S-Off users, correct?
flashing files from hboot is definately not s on or off specific. if youre s-on,its just more of a pain,as there are more rules that apply when s on,but thats the case for any type of flashing,really,and why most of us strive for s off
i mess with lots of htc phones,and its become quite cumbersome to physically keep moving files on and off the sd card,so ive been using the "ruu" method for awhile.
AFAIK, you cannot flash zip files from the bootloader when S-ON unless they are signed by HTC, but I'll PM scotty85 to clarify that since things may different on the Rezound or using the fastboot method.
pretty much all the newer htcs behave the same way. the rezound is quite similar to the 3d in specs,ram,processor,etc.
you can flash files from hboot on the sd card,or with the fastboot method while s-on. basically while s-on:
1)unsigned files must be
only the allowed partitions(system,boot,recovery)
2)signed by htc files must have the bootloader
relocked since they normally contain partitions that are not changeble with an unlocked phone(hboot,radio,etc)
3)wether signed,or unsigned, files must pass all the "usual" checks-main version,cid,etc. before the bootloader willallow the flash in hboot,or from fastboot.
since the info on the android info text document is relevant with s-on, its a good habit to get into,to flash the main version low zip prior to any flashing. when i first got the rezound it drove me nuts trying to figure out why some PxxxIMG file would flash,and some wouldnt
flashing the main version low zip sets the main version to 1.00.000.0 so that pretty much anything relying on a main version check will pass it.(note that changing the main version alone will not let you dowgrade to older firmware while s on. the phones are checking more than just that to flash whole,signed pacakages)
I assumed as much. I've used that fastboot flash zip method before, for the RUU. Wine+Linux didn't run the full RUU, so that's how I did it.
Reading this part here:
1)make sure the file only contains changeable images-i.e. boot,system,or recovery
2)make sure the android info document contains the same or higher main version than what is on your phone currently.
Makes me think that it would be more for ROM updates and whatnot, instead of radios/hboot/etc. I could be wrong, though.
while s-on,this is pretty much true. you can run "rom.zip" extracted from a .exe utility via the fastboot method,if the utility is giving you fits.
bout the only other reason,really,to use it with s-on,would be if you want to flash "mini-ruus" rather than relocking and running whole ruus. before getting s-off on the rezound,i used to pull the boot and system images from leaks,pack them up and flash them,so i wouldnt have to upgrade to leaked firmware that may suck
the
fastboot flash command can easily be used to flash recoveries and boot images,and is a a couple less steps than the fastboot ruu method,so thats typically how i changed kernels when i was s on.
i typed that kinda fast,so hope it makes sense. just holler if you have further questions
