You might need to do

chromefy cyan v69 / caroline v69 first if above does not works - after powerwashing, then repeat the above steps :(

Notes -

* this hack also works for flashed or non flashed firmware Chromebooks (with FydeOS 5.3.1)...

* using post 1 method to keep original kernel also works but only with ATB 55 if not flashed...

* flashing the firmware needs to be done properly, so always backup the firmware when prompted...

* flashing the firmware is a great idea, it makes the Chromebook more versatile...

* one can use ATB v72+ & FydeOS 6+ on the flashed firmware Chromebook, so more ROMs to play with...

* & using post 1 method on ATB v72 gives a fully functional with original firmware Chromebook...

Disclaimer -

I have only Acer C720P so for other Chromebooks, mileage vary...

Extra Notes -

* above hack used to yield camera migration for Acer Iconia W700, not anymore - which made me suspect as I posted earlier, that camera gets upgraded in the background by googledevs irrespective of the recovery ROMs used, & they seem to have crippled it so it cannot use camera migration on non Chromebooks.

Chrome OS R70 on 2014 Chromebook C720P using [MENTION=281641]Chromefy[/MENTION]

script from USB & arguments: chromeos_11021.81.0_eve_recovery_stable-channel & chromeos_10895.78.0_caroline_recovery_stable-channel_mp - + great news from [MENTION=4134963]arnoldthebat[/MENTION]

- Chromium OS R71 release imminent via [MENTION=228437]xdadevelopers[/MENTION]

maybe this could still yield camera migration for Acer Iconia W700 (after chromefy nocturne)

* Getting camera migration working on Acer Iconia W700 still possible - needs FydeOS 5.3.1 - Nocturne v71 - cyan v70 - caroline v69 - boring, but could not find any other way...

2 USB's each with FydeOS 5.3.1 - one to boot from, 2nd target to chromefy to...

Use older version of chromefy -

1. chromefy FydeOS 5.3.1 with Nocturne - answer no twice when prompted

2. chromefy result FydeOS 5.3.1 Nocturne with chromefy cyan v70 caroline v69

answer yes to first prompt, & no to second prompt -

- you now get a solid Chrome OS v70 with camera migration, etc (of course no google assistant with cyan).

So far unable to replicate it with eve.

works with eve v70 too... as above but amend as follows -

* Getting camera migration working on Acer Iconia W700 still possible - needs ATB v72 - Nocturne v71 - eve v70 - caroline v69 - includes Google Assistant too ;)

works with eve v71 too... as above but amend as follows -

use 2 USB's with ATB v72

1. chromefy ATB v72 with Nocturne - answer no twice when prompted

2. chromefy result ATB v72 Nocturne with chromefy eve v71 caroline v69

answer yes to first prompt & no to second prompt

3. boot the result - will not allow to login (OK)

4. chromefy result with chromefy eve v71 swtpm.tar

answer yes to first prompt & no to second prompt

some interesting outcomes with eve 70 / 71 on Acer Iconia W700

- in eve 70, penguin crostini kernel is 4.14.67 (which is also FydeOS 5.3.1 kernel)

- in eve 71, penguin crostini kernel is 4.14.74 (ATB v72 kernel is 4.14.83)

Linux penguin 4.14.74-07776-gac52e5f750c8 #1 SMP PREEMPT Thu Dec 6 17:36:39 PST 2018 x86_64 GNU/Linux

in eve 70, camera migration is in native camera, webstore app works lauched from webstore...

in eve 71, camera migration is accessed through third party Android apps, native camera webstore app is the default.

eve 72 uses Android Pie which I have not been able to get to work with camera migration in Acer Iconia W700 (neither with ATB v72 & FydeOS 6.0)

In both error message when doing

$ sudo apt-get update

cyan v71 gives camera migration

cyan v72 does not give camera migration

cyan v73 gives camera migration (which is great as it's latest so far)

All releases for strago platforms, like cyan have Android Nougat 7.1.1 - I don't think they will recieve Android Pie (their original Linux Kernel is 3.18)

new releases though might remove it again :(
