Can't flash or boot recovery on oneplus (ab slots)

[aibd]

May I first ask which of the Different Build Types you are trying to install ?

My reading of the difficulties over the past 12 months is that installing the Android 13 (T) version which is a community build is much more likely to be successful than the stable build which is still on Android 12 (S)

I searched one thread that particularly sticks in my mind and quote the closing post (with an edit for typo)

@langedarm

So my advice to everyone who want to install E on a Oneplus Nord: FORGET ABOUT THE STABLE ANDROID S VERSION AND GO STRAIGHT TO THE DEV VERSION ANDROID T.

I would prefer the e-Recovery to TWRP from an install point of view.

Edit This nord install story comes in 2 parts:

• After flashing TWRP only bootloader accessible – note TWRP not recommended for an easy install, special instructions are linked.
• Error applying update: 29 (OnePlus Nord - avicii. Fixed by changing install plan from Android 12 (S) to Android 13 (T).
