Oneplus 6T userdata

[hxrofo]

hi
I've been trying to install it on my Oneplus 6T (fajita) for over a week now, but it fails every time. OP6T has no sdcard slot, so I-m trying to install to EMMC using fastboot. The boot.img installs without problems to slot A or B, but the rootfs.img is bigger than the userdata space, or at least that's why I understood so far. This is the message I get:
fastboot flash userdata rootfs.img Warning: skip copying userdata image avb footer (userdata partition size: 118112366592, userdata image size: 140724372960656). Sending sparse 'userdata' 1/4 (744601 KB) OKAY [ 24.681s] Writing 'userdata' OKAY [ 0.007s] Sending sparse 'userdata' 2/4 (782466 KB) OKAY [ 49.254s] Writing 'userdata' OKAY [ 0.002s] Sending sparse 'userdata' 3/4 (752397 KB) OKAY [ 63.010s] Writing 'userdata' OKAY [ 0.008s] Sending sparse 'userdata' 4/4 (765831 KB) OKAY [ 56.397s] Writing 'userdata' OKAY [ 0.010s] Finished. Total time: 203.493s
and after it finishes, when I reboot it keeps booting to fastboot main page. Partition A is rooted and has LineageOS 21 installed. I tried installing to both slots, but everytime the same errors. Any suggestions to what might be wrong or if I'm missing something? thank you

Have you erased dtbo? Also try to flash only boot.img and see if you can get initramfs console.

You can flash twrp or boot twrp image from fastboot and flash lineageos zip.
