For completeness' sake: if you did not unlock the bootloader before, the unlock tool will remain as functional as it would have been in the first place. If you can't unlock the new bootloader, you couldn't have unlocked the old one either (issue is on ASUS' side, well referenced on the forum).

Reflashing an older bootloader: no, unless you have NvFlash and the concurrent backup files-- I didn't gather you ran that procedure before upgrading to .30...

TL;DR: your bootloader will remain unlocked if you unlocked it prior to updating, and remains unlockable if not.

fantastic. thanks for the detailed reply.
any idea if the reboot to recovery thing is BL-related? if so, would upgrading it solve the problem? or is the tf700 owner's club SOL with that?

Maybe. It works for me, with the 10.4.4.25 bootloader.

In any case, before you use any "reboot to recovery" tool after flashing a new recovery, always test the new recovery by starting it at least once with the power/volume button combination.

My pleasure!

I had a boot-to-recovery loop once with CM10 -- that was a hairpuller. After doing some research (all the while hair-pulling, to be honest), this zip solved it. So as far as I'm concerned, that'd be a yes.

This is always sound advice -- the older recoveries indeed have caused quite a few splitting headaches.

thank you, fellas!

EDIT: I upgraded my bootloader successfully. I can now issue the "reboot recovery" command and end up in CWMR. Thanks again!
