[Q] I dont know what the problems is?

[yj121]

Hi, so I've been flashing for a while now on my phone and my friend wanted to root his phone so i agreed to help him out. After flashing multiple files in order to get cwm recovery and just get everything working, the phone started to act up.
Here are the problems:
Phone can boot into stock recovery but i cant flash anything from it
i wiped data/factory reset many times.
i tried to install the cwm kernal by applying update from sd card (I followed the install custom recovery instructions from here: http://wiki.cyanogenmod.org/w/Install_CM_for_i777) but when into recovery to flash, 2 red signs come up saying "E: Failed to verify whole-file signature" and "E: signature verificatoin failed" after this is just aborts the process
i tried download mode, but none of my computers recocgnize the phone (2 computers) i have tried all usb ports, reinstalling usb drivers, different usb ports many times but all have failed
if i try to boot, the phone just stays stuck on the Samsung galaxy s2 logo (no triangle? even though its rooted)

my only option is to hang out in recovery, i have a bunch of files saved to an external sd card but i cannot access that from stock recovery
any help would be appreciated, Thanks

You can not install any unsigned files with stock 3e recovery, as you have discovered. That is normal behavior.

I don't know why performing a wipe data/factory reset from 3e recovery does not clear the phone to boot normally. It should. But since it won't...

You will need to get the phone recognized by a computer, and then flash with Odin, or you could try flashing with Heimdall command line. I would suggest that you flash the full stock plus root I777UCKH7 (2.3.4), and then when it boots normally into the system, install Mobile Odin Lite or Mobile Odin Pro, and use that to flash a custom kernel. You can find the stock firmware in the Download Repository, and the basic directions in my guide, both of which are linked in my signature.

The hardest part about this is getting my computers to recognize the phone

i guess i shouldve mentioned this earlier, i attempted to flash in Odin but it was stuck on zImage so i unplugged it

before i flashed in odin, i used to be able to boot into the phone like touchwiz and whatnot, now it just gets stuck on the samsung galaxy s ii boot logo

This is now [Solved}! thanks for the help creepyncrawly! i figured it out after doing some more reasearch online. apparently, youre not supposed to use the charger wire that came with the device since samsung doesnt want to waste their time on creating a good enough cable for this kind of stuff. so i grabbed some random cable that i found in my house, hooked it up and BAM! both of my computers were able to detect my phone just finished flashing bone stock on the phone thanks

I noticed in your post that you tried everything but another cable. But I'm glad you got it working. I had the same problem before too. Cables are finicky little things.
