hi sony,
i followed your instructions and used the opda cert and key to sign the apps using freesigner but i sill get “certificate error”
would you know why this is still happening?
I also faced the same problem but most of the application have no certificate error after resigning. If resigning won’t work then follow manual installation with the original file.

it has this msg . “wrong IMEI,please check carefully”
i keyed 13+ 9 other number.
can you advise me?
you need to enter your IMEI number only in the IMEI number field and confirm IMEI field.
13+9 other numbers in the phone number field.
Sry, Pardon my ignorance. What’s IMEI. Where can i find this number?
IMEI stands for International Mobile Equipment Identity. You can find it on your mobile just by *#06# on your dial pad.
