Aaand that's why you probably have this issue.8. type fastboot -w
9. type fastboot erase userdata
10. type fastboot boot twrp-name.img
11. push ROM.zip to internal storage via using command prompt by typing (adb push ROM.zip /sdcard) or copy paste to internal storage if it is accessible from file explorer on your computer.
12. flash ROM.zip ( by default skip digest check will be enabled so don't untick & don't tick anything extra )
13. swipe to flash
14. reboot system
Enter fastboot and start flashing from step 8, just like I flashed asop13, it is pe flashed directly from aosp
1. go back to stock ROM. Use LMSA for this.
2. when you're ready to flash this ROM, do:
fastboot erase userdata
fastboot boot twrp.img(twrp filename can differ)
4. if you have an SD Card, copy the ROM onto your SD Card. It's gonna be a lot easier.
5. if you don't have an SD Card, you can use adb to push the ROM onto internal memory. But...I couldn't find the correct path. So...this step didn't work for me, and I ended up doing this instead:
adb sideload path-to-ROM.zip
I guess you could do whatever method you want. But I feel like flashing from an SD Card might be the easiest way. Ooor...sideloading.
fastboot rebootOoor, just reboot from the Power button.
I think, in your case, there might be some things left from AOSP 13. So that's why I suggested going back to stock ROM first, then flashing this.
