I'm having a heck of a time just getting twrp booted. I only have experience with one other device so maybe there's something obvious here.
I'm using
twrp-3.6.0_9-0-taimen.img.
The output of (fastboot boot twrp-3.6.0_9-0-taimen.img)
downloading 'boot.img'...
OKAY [ 1.133s]
booting...
FAILED (remote: dtb not found)
finished. total time: 2.290s
The instruction at the top of this thread say to use (fastboot boot ...) while the wiki that is linked says to use (fastboot flash boot ...) Which one is right?
The TWRP page for taimen says
"If you accidently flash TWRP to your device using fastboot instead of temporarily booting the image, you will need to download the latest factory image for your device and reflash the boot image."
If I run (fastboot flash boot twrp-3.6.0_9-0-taimen.img) I get this:
target reported max download size of 536870912 bytes
sending 'boot_b' (40960 KB)...
OKAY [ 1.202s]
writing 'boot_b'...
FAILED (remote: size too large)
finished. total time: 1.251s
I switched to slot a with the same results.
Any help would be greatly appreciated.
