Flash in Hboot
*first and foremost,while it is really cool to have an engineering,security off bootloader,it comes with great responsibility. flashing a bad or incomplete file in hboot can brick your device,so use extreme caution.
-make sure you are only using files from reputable,known developers
-make sure you are checking the integrity of files by verifying md5 sums
-make sure your phone is well charged,as powering off during a flash could be very,very bad.
so here is the safest way that i know of to flash files in hboot:
1)download the file to your computer *note:do not unzip
2)use a file verifier to compare the md5 sum of your download to that listed for the file.there are lots of free file verifiers,heres an example here: Home of the MD5summer . this saves you from transfering a bad file to your phone,but is a somewhat optional step.
3)connect your phone to your computer and place it in disc drive mode. transfer the download to the root of the sd card(top level-not inside a folder) however you are comfortable. i personally open a couple of windows explorer windows and drag the download from one window to another.
4)rename the file on your sd card to "PG05IMG" if youre using windows. if youre using something else,you may have to add the ".zip" manually to the file name. windows likes to add the file extension automatically,then hide it,so if you type in "PG05IMG.zip" you may be actually naming the file to "PG05IMG.zip.zip". also please note that is a number zero,not a letter "O"
5)if you havent done so allready,now is a good time to right click on the drive that represents your phone in a windows explorer window,and then click "properties". your phones sd card MUST be formatted FAT32 in order for an hboot flash to work. if you find now that your sd card is formatted something else,youll need to back up everything on it to your computer,and re-format it to FAT32.
6) eject your phone from your computer first. then select charge only mode on the phone. if the phone has sufficient charge(some say 70%,i personally charge mine all the way) unplug the usb cable.
7)f youre currently on a custom rom,go to settings/power and make sure "enable fastboot" does NOT have a checkmark,as this will prevent you from entering hboot from a powered off state.
8) check the md5 sum again. you can use astro file manager,or a market app called "scary aliens android file verifier". this is the most important preventative step,IMO,as THIS IS THE FILE that youre going to flash. it could have become corrupted tranfering it over,so just because it was right on your computer,does not mean that its safe.
9) power off your phone
10)power on while holding volume down. if you have named the file correctly,and have a properly formatted sd card,the phone will find the file. youll see a couple status bars as the it unpacks it,then checks it. when its done it will ask you if you want to update.
11)select yes to update by pressing volume up.
12) youll see more status bars as the phone does things. if youre flashing a full ruu,sit back its going to take awhile. at this point i gently sit my phone down and let it do its thing. you dont want to drop it and have it land on the power button,or spit out the battery,so put it down and dont mess with it.
13) when the update is complete,it will tell you so. in some cases you may have an option not to reboot,in wich case you could manuver to recovery if you have something to do there. otherwise,reboot.
14) upon reboot,IMMEDIATELY DELETE the PG05IMG file from your sd card,as every time you enter hboot,the phone will find it,and try to update. this can be a big problem if you are stuck in a bootloop,hung up at a spash screen,or have some other problem that you need to get to recovery to fix.
enjoy your new radio,splash image,recovery,or whatever it was you just flashed
