[Q] sign update.zip for e3 recovery - Android Q&A, Help & Troubleshooting

Hello guys!
I've this tablet: Mediacom 722i with Amlogic AML8726 M3.
I want to do something with the original rom on the website of Mediacom.
I've a great problem to sign the update.zip that i create.
I used SignApk and nothing, the e3 recovery always tell me that the verification of the signature is failed.
I used ZipSigner for Android and the same error from the e3 recovery...
How i can sign the update.zip for this tablet?
The original update from the website of Mediacom is signed by SignApk.
Why my update.zip isn't good for e3 recovery?
P.s. this tablet hasn't CWM
Thanks in advance!

Anyone can help me?

did you find the solution for this problem?
thanks

The device may need to have an official OEM sig, not just a generic one. Often this is the case with this type of recovery for any update.zips
