My galaxy a3 is not booting up after I installed cm 13 - Galaxy A3, A5, A7, A8, A9 Q&A, Help & Troubleshoot

Hello everyone, can you please help! I have the SM-A300F model and I've been trying for a week to install the cm 13 unofficial rom, I installed the twrp 3.0.0-0 recovery and downloaded the files and wiped Dalvik / ART Cache, system, cache and data. then I installed the rom then the gapps and then the super su, but when i reboot to system, it always gets stuck on the cm logo, I waited for one whole day and it was still on the cm logo, it didn't boot up, i don't know what's happening with me, i think I am having a bootloop. Thanks a lot for reading, can you please help solve this problem?

Soft bricked? (solved)

Hello there,
I was installing latest Build of PA rom, I downloaded it from someone's mirror, I went to twrp then wiped data, system, cache, dalvik and usb otg. Wipe failed.. Then I noticed I by mistake selected usb otg, I deselected it and wiped again and it was successful. Then i went to install and installed rom then installed gapps and then kernel (martix) and rebooted phone. It was stuck on google logo. I went to fastboot mode and then into recovery then wiped and installed previous build but I'm still stuck to boot logo (google) Now I want to know if I can recover my data from internal storage somehow in twrp or fastboot mode.. or I can unbrick device without loosing any data of mine..
Any help would be appreciate thanks..

My G2 won't load any rom at all...

The problem started yesterday. Did an OTA update from CM11 to CM12 but it caused so many problems so I booted to TWRP, wiped everything clean, transferred CM12 to my via Fastboot and did a clean install. Rebooted and it just lingers on the boot logo for ages. I tried the wipe and install again, same problem. I wiped my dalvik & cache, same problem....
So I thought maybe that version of CM was just buggy so I wiped again, transferred Resurrection Remix via Fastboot and installed that. It was at the boot logo for an hour before I gave up and turned it off.
I've never had a problem like this which has spanned between different roms, what could be the problem? I'm installing stock now, hopefully that works so I can try again

If you note a problem like this after installing a rom, i think you can try format data, not a simple wipe but a format in twrp

TWRP Loop

***Problem Solved***
Hello All,
First of all, Iam a newbie in custom roms so i hope it's not a stupid question...
Couple of months ago i rooted my LG G2 en installed TWRP and after that i flashed Lineageos 14.1.
But i wanna try something else.
I flashed AOSP and works like a charm.
So i decided to flash another one.
But now my phone is stuck on a TWRP loop.
I aleady update twrp to a new version: 3.2.1.0 but it still not work.
What did i do:
Iam going to wipe.
Advanced wipe and wipe:
Dalvik/ART cache
System
Data
And cache
After that iam going to Install:
select the rom and the OpenGapps. (ARM 7.1 Nano)
And confirm flash.
After the flash i wipe Cache and Dalvik and then reboot..
But it's only starting in recovery again and again.
I have tried this roms:
Lineageos
ASOP
CRdroid
Paranoid Android
MK
Ressurection remix
But none of the roms will work
I also tried to wipe Internal storage but unfortunatly that also doesnt work
What iam doing wrong?
Or what can i do to get one of this roms to work?
Thank you
***Problem Solved***
I Found it!!
By Terminal i have to type a code and then another code.
My phone is working again.

Bootloop to TWRP after installing LineageOS

Hello,
iam stuck in a Bootloop that goes straight back to twrp.
I got a refubirshed Mi 9 T with MIUI 11 and wanted to install LineageOS.
I unlocked my bootloader with the miflash_unlock tool (didnt had to wait).
Installed latest twrp (twrp-3.3.1-0-davinci.img)
Flashed twrp (fastboot.exe flash recovery twrp.img)
Wiped Dalvik, Cache, System, Vendor, Data
Installed LineageOS 17.1 and gapps nano
After that my Phone reboots straight into twrp and i dont know what to do or what i missed.
I set up a pattern so i guess my filesystem is encrypted but i dont know if it matters.
Does somebody know a solution?
Kind Regards

Solved it.
I had to wipe the /data/ Partition
please push format data (button), reboot in twrp and install lineage too
If that doesn't work, you can install vbmeta
