Sorry, I Don't know where to post this ,i posted it here according to my mobile model(S2) but now my problem is with (s7562).. & Sorry for my English.

I'm searching for an effective solution to
1- ""Can't mount /sdcard" for both internal & external one"
2-Signature Verification Failed
3-Is it possible to connect Samsung devices via fastboot ? or only ADB ?
Note:Any solution asks for reinstall the rom or doing factory reset is NOT accepted for me

Hi All, ^_^
i spent my day trying to solve a problem ,more than 12 hours straight
& FINALLY ^__^,
i didn't solve it & I'm going to dream with it...

i have a problem with my s7562 ,actually they are problems

#My main problem is that i want to root my phone &&& finally i rooted it using Kingo app & it was easy & effective.
"Kingo" roots my phone & installs "Super User" but it does not install a new CWM for the recovery...

The problem is that i managed to change my current (Android System Recovery <3e>) with a new CWM because (Android System Recovery <3e>) :
1-always says: "Signature Verification Failed"
2-there is no ability to access the internal sd

I tried many CWM a flash-able zips form both "odin" & CWM but it always fails due to this problems:
1-when i try to enter CWM the phone hangs at Samsung logo
2-OR i can enter cwm but i cant access my sdcard,internal sd >>"Can't mount /sdcard" for both internal & external one

For the first problem (Signature Verification Failed) i tried this article
& signed the zip >same problem
& i search for " Toggle Signature Verification " option in my CWM & i didn't find it

For the second problem ,i read that the cwm is the cause of this problem "Can't mount /sdcard" & i have to install a new one,
i tried may CWMs & nothing works & i found many CWMs as (.img) files then i used this article to make then a flash-able (.tar) files
flashed successfully & nothing works
note,when i return to the stock cwm i can only access the external sd,but zips installation fails due to "Signature Verification Failed"

ALSO i tried to install the cwm via ADB but i faced problems in that,this is the xda article

Thank you for your attention
Any Help would be appropriated
Regards ♥ ♥ ♥
