I got a regular Jelly (no pro) and after I tried yo root my phone, I got a nice brick.
First I unlocked the bootloader by adb, then I also uploaded twrp with adb. Rebooted into twrp, I made the mistake to allow TWRP to modify the system, then I installed magisk 14 via twrp from the sd card. When I rebooted the phone, it stucked showing Unihwrtz logo.I tried to recover the phone flashing by abd the original boot and recovery. I made a factory reset from the original recovery and nothing, the same.I tried it several times and several ways and still no works.
Hopefully a day will appear a original rom backup to falsh it via TRWP
Thanks guys for your help

What bricked your Jelly? TWRP or magisk 14? I would be interested in which TWRP you used if that was successful

I exactly don't know wich caused the brick. Probably was magisk.zip flashed trough TWRP.
The TRWP version I used was the same one shared in this forum to do it

TWRP is the one which bricked your device. Jelly is hardened and uses dm-verity. Twrp touched system and verity never succeeds and hence android will not boot.

You can recover by installing a custom boot.img with verify disabled. Do you have a stock boot.img from Jelly?

You can factory reset - does that help?

Did you try the solution found in post 22 here? Did the same, now it is working!

I did almost the same thing.
Integrity check in Adroid Recovery shows "load source zip fail". Graphics check shows error.
When I try to reload from TWRP it says "No OS installed. Are you sure?"
So, looks like we need stock rom zip to flash?

I've found Jelly (no pro) old image. Not so well, but better then nothing. Will do for a while

For reference, the scatter file in the download above does not work (not a valid scatter file).

In my bricked Pro I had success using a MT6737M scatter file (unfortunately it won't boot due to different partitions).
