Hello and thank you for your fair initiative !
I just ran the update 1.4.2 and at reboot I got the boot menu with, at the screen bottom, the following error message:
[...] Verifying update package... E:footer is wring E:signature verification failed Installation aborted. E:Can't open /dev/block/platform/msm_sdcc.1/by-name/misc (Permission denied)
Then I selected first reboot option and my phone booted normally. Even though I had to enter my SIM code with very low brightness.
Updater still suggest me to install 1.4.2.
What should I do ?
