Noob question - HBOOT: ENG S-OFF state

[Guest sonicjuice]

Hey all

Just a quick question from a newbie to Android.

I've got an N1 holiday/developer phone with an SPL of ENG S-OFF which allows me to relock via fastboot. At this time I'm still running the stock build that came with the phone but I'm keen to move up to Froyo via signed zips (initially, just to see how things are - I'm going to move to a custom modaco ROM later).

Anyway, noob question is: By flashing the PASSIMG signed ROMS and also, later on, custom ROMS I'm not actually at risk of losing my ENG S-OFF status am I? I notice that in the ERD79 PASSIMG there is an HBOOT.img and stuff.

I wouldn't like to lose my ability to easily relock etc just by upgrading to a newer build! :angry:

cheers, Thomas

p.s. if I download the build upgrades as signed ROMs I assume all I need to do to install them is copy the zip to the root of the SDCard and boot into recovery - and it'll automatically upgrade itself? Is that correct - I don't need to mess around with fastboot or anything?
