v2 Goggles unable to lock about margerine

[j005u]

I assume you're trying to undo wtfos? Do the following:

adb shell
opkg remove --force-removal-of-dependent-packages wtfos wtfos-system
wtfos-remove-adb
reboot

Skip the wtfos-remove-adb if you wish to retain basic adb access.
margerine.js lock isn't currently working properly.

[DimitarKrastev]

Actually I never got to wtfos. I want to.
I initially unlocked with the master branch. I wasnt sure if the unlock feature in the 1.1-wip branch is different, so I decided to lock, refresh firmware, then switch to 1.1-wip, unlock and install wtfos and msp osd.

If I previously unlocked with master, can I just switch to 1.1-wip and execute node margerine.js payload to install wtfos and then proceed with msp osd?

[j005u]

Yes, you can do that.

[DimitarKrastev]

So, if I previously unlocked with master, I am safe to switch to 1.1-wip and install wtfos? No need to lock/refresh/unlock firmware?

[j005u]

Yes, that's fine to do.

Also, msp-osd currently has a bug in the package and it crashes when you activate it.

You can use mv /opt/etc/fonts /opt/etc/font.bin && mkdir /opt/etc/fonts && mv /opt/etc/font.bin /opt/etc/fonts/font.bin to fix it after installing the package on goggles.

The package should get a fix soon.

[DimitarKrastev]

Yeah, I noticed that it is probably crashing, I will apply the fix now, thanks.

Anything specific you need tested?

[DimitarKrastev]

I installed the msp-osd-goggles package, opened the terminal and executed the command, but got:
mv: bad '/opt/etc/fonts': No such file or directory

[j005u]

Sorry, it's

mv /opt/fonts /opt/font.bin
mkdir /opt/fonts
mv /opt/font.bin /opt/fonts/font.bin

[DimitarKrastev]

OK, that did it. Thanks, I will play arround with it.

I also have the same issue with the v1 Goggles.

found GP150

I've tried to lock them in order to test Root from Browser fpv-wtf/wtfos-configurator#4

I've uninstalled WTFOS from the Browser, though, so maybe the another issue is better placed there.

[j005u]

Uninstall wtfos via the configurator. You'll still have CLI (adb) access, run:
wtfos-remove-adb

Margerine needs an update, it's trying to run an old uninstall method that is no longer compatible.

[DimitarKrastev]

Any ETA for this? I would really like to revert to stock and refresh my firmware. I am experiencing weird issues with DJI menus freezing or lagging taking 10 seconds to register a click, etc. Thanks

[Alia5]

Joonas already posted the solution

Uninstall wtfos via the configurator. You'll still have CLI (adb) access, run:
wtfos-remove-adb

This will re-lock your goggles.

From what I've gathered, after that you might wan't to downgrade and re-update your goggles via DJI configurator

[j005u]

@DimitarKrastev yeah, what @Alia5 posted. If you want a full reset then you need to downgrade and upgrade otherwise dji_upgrade won't actually flash things.

Could you at least tell us which packages you had installed that started to cause this problem?
Or ideally, try disabling all startup items and see if the problem persists?

I've been flying with a wtfos install daily and haven't seen such problems yet, but it could be some weird interaction between different packages.
