what do you mean,"it didnt seem to work?" did it give you an error message? or did it appear successful,but the phone still wont boot?
as the guys have said,with s on you cannot install the boot image from a permanent recovery. the recovery must be launched from fastboot into memory,or the boot.img must be installed manually.
a couple things about installing manually:
-the boot image muct be from the rom youre trying to install,as they are all different across roms. some may compatible,some may not.
-the boot image must be in your folder with the sdk tools adb,and fastboot. if you used the file above,the boot.img must be in the "mini-sdk" folder.
the other option is launching recovery from fastboot,wich well get to in a minute.
error 140 could pop up because the main version of the rom is higher than the ruu your trying to install,or the hboot is newer. s-on will not let you back-track in software builds or firmware,meaning you cant install older RUUs.
the ruu you should be using is this one:
Androidfiles RUU
if it fails,you may need to lower your main version.you can do that by:
-download setmainversionlow.zip from this post:
http://forum.xda-developers.com/showpost.php?p=23169557&postcount=4
-re-unlock your bootloader(you can use your original token)
-enter recovery,via hboot
-flash main version low zip file from recovery
-relock bootloader
-run ruu
before you do that, i suggest we try and install a stock,rooted rom.
-go to
this thread and download
Shooter_ICS_35_S_Sprint_WWE_2.89.651.2_odex
-you should still have a recovery image in your fastboot folder on your PC. when you first rooted,you undoubtedly permantly installed it using this command:
fastboot flash recovery recovery.img. "we are going to do something similar,but use a slightly different command to immediately load recovery into memory. plug in,make sure phone is in fastboot(you should see
fastboot usb),open cmd window,change to adb/fastboot directory,and then use this command:"
fastboot boot imagename.img
so if your recovery image is named simply "recovery" then you will:
fastboot boot recovery.img
shortly thereafter,your recovery should pop up on the phone. you can now:
-enable usb storage and trasnfer the rom to your sd card(or have moved it prior with an sd card reader,wichever is less confusing for you)
-wipe data/factory reset
-wipe cache
-wipe dalvik cache
-install the stock rom linked above
-reboot
launching recovery from fastboot in this manner will basically make your phone think its s off

for lack of a better explanation. whenever you
fastboot boot recovery a seperate boot image flash should not be needed.
let us know what happens. once you have a working phone again,we can help you get your rom of choice installed. as DS has mentioned,not all are compatible with all firmware,so youll need to either s-off,or chose one compatible with your 1.58 hboot.
hope that helps
