[Very Technical] Did fastboot returns wrong bootloader lock state for MRA58K?

[kschang]

Was using WugFresh's Nexus Root Toolkit, updated N7 to MRA58K. Try to update to 58U, and got "bootloader still locked", when I know for sure it was NOT locked as I was able to update to M from L previously.

So I did a little digging in Fastboot.

One way to get bootloader status is

fastboot oem device-info

This returns, among other things

Device unlocked: false

However, using a different command

fastboot getvar lock_state

(or getvar all if that doesn't work)

Got me instead...

(bootloader)   lock_state: unlocked

Which is the result I was expecting.

So, you think someone over at Nexus ROM patching screwed up the oem device-info output? Or did I interpreted the flags wrong? Which flag to trust? Should they say the same thing?

Plot thickens. According to Chris Simmonds, a Linux consultant who also do Android, bootloader status is shown in "secure" variable. I'll have to double check both my Moto X and my Nexus 7.

Maybe our beloved N7 20113 is in some transient state with its actual MM stock factory image versions regarding ability to answer queries for bootloader to see if the device is unlocked...
I am getting still the same result as you even on 6.0.0 MRA58V (unlocked):

C:\>fastboot oem device-info
...
(bootloader)    Device tampered: false
(bootloader)    Device unlocked: false
(bootloader)    SB=Y
OKAY [  0.000s]
finished. total time: 0.000s

C:\>fastboot getvar lock_state
lock_state: unlocked
finished. total time: -0.000s

C:\>fastboot flashing get_unlock_ability
...
FAILED (remote: unknown command)
finished. total time: -0.000s

So the ROM *did* change on us, hmmm!

2.07 is out and the problem seem to be fixed. Flashed 58V last night.
