Hi,

I am trying to install /e/ on my FP2. I’ve followed the instructions but I get an error on the last step “Sideload the /e/ .zip package”.

The command adb sideload e-0.5-n-201903013788-dev-FP2.zip initiates and the transfer starts but it systematically fails around 50%.

The output of the terminal is Total xfer: 1.00x.
The output on the device is Zip signature verification failed.

I have check the settings of the TWP and the zip signature verification option is unchecked.

I’ve used to following TWP image: twrp-3.2.3-0-FP2.img

Any idea what could be the problem?

Thanks,

Figured it out. I used a different version of TWP: twrp-3.2.2-0-FP2.img

The Zip signature verification did not happen and I was able to boot /e/.

Usualy happens with an outdated version of TWR recovery.

Try reflashing twrp-3.2.3-0-FP2.img
