The inevitable Secure Boot thread

[trter10-imore]

So guys, what's with the secure boot?

Can't flash recovery or boot, and I'm assuming this is why.

Does anybody have any ideas on how to disable it/work around it, or even what it is?

Thanks!

You can boot a recovery and flash su for root. Read my guide.

Right but it worries me that one can't be fully flashed like usual

Course it can.. You probably need to just delete or rename the recovery-from-boot.p file from /system before you can flash a custom recovery permanently, that's how it is on ICS and other JB versions.

Any chance of a temp root method, without unlocking?

Not yet, then again i doubt any 4.1 exploits have been tested.

Just unlock, it's what nexii are for

Would prefer to temp root, do what I need and unroot. I'll keep an eye out then.

 

[trter10-imore]

Ah I see. I'll let you know if I see anything

@trter10 -- Hey, have you found out any more info on this secure boot thing? Lol I have to admit I'm getting a little bit confused by it.. it's seemingly giving kernel and recovery developers some head-scratching too as they try and get custom kernels to flash properly on this thing. Think I originally misunderstood what the deal was and now having trouble finding solid info... appreciate any light you can shed

No idea
It seems like almost a checksum verifier since it lets the stock boot be flashed and it boots afterwards, but fails on a modified boot image that will boot from Fastboot boot boot.img... but I saw a dev on XDA get a custom kernel booting but I'm not sure if he used Fastboot or recovery to flash.
It may also just be a signature checker since I think the guy on XDA built from source and modified the source directly, and compiling added a signature whereas just splitting, editing, and recompiling does not.

I've never had a nexus before last week and ive never had a successful attempt at building a kernel (ignoring integrated kernel building in CM9) so I'm just as lost as everyone else.

OK my thumbs hurt now I'm going to stop
