Guys, i need some help. My cellphone was with a lot of stuck on apps, and i tried factory restoring a lot of times to solve, and i tried upgrading to Android 9 too. After all, i resolved to root the device in order to fix the errors. But I made some mistake in the rooting and it doesn't work. Now I can't put the device to work, i tried all the tutorials here and a lot of roms, but i always get a diferente problem.
I always get "(bootloader) Image signed with key bad key" message when I make the tutorials, I dont know if this is the problem. In some tutorials I get a bootloader looping, in others the device try to initiate and the screen stays flashing, but in any of them the system starts.
If you can help me, i'll thank a lot.
In my bootloader show the following informations:
BL: MBM-2.1-aljeter-retail-02dae09-190122
Baseband: M8937-30.05.80R JETER-LATAMDSDS-CUST
Product/Variant: jeter XT1922-5 32GB P4
Console (NULL): null
Tool Modes Config: DISABLED
flashing_unlocked
