https://mrchromebox.tech/#fwscript

To download and run the script, from a terminal/shell type:

cd; curl -LO https://mrchromebox.tech/firmware-util.sh && sudo bash firmware-util.sh

3. Install/Update Custom coreboot Firmware (Full ROM)

As this is a full replacement firmware, the script will offer users the option to back up their stock firmware on USB. Chromebox users have the option of a Legacy Boot or UEFI compatible firmware. When the Legacy Boot option is selected, users will have the option to set the default boot device (internal storage [default] or USB/SD); Haswell/Broadwell Chromebox users will also have the option to enable "headless" (no display attached) booting, as well as the option to enable PXE (Ethernet/network) booting via iPXE. If PXE support is enabled, it can also be set to be the default boot device. As before, changing any of these boot options requires re-running this script function.

Since Haswell/Broadwell/Baytrail Chromeboxes store their Ethernet MAC address in the VPD (vital product data) region of the stock firmware, the script will extract that region from the stock firmware and inject it into the new firmware ensuring the unique MAC address isn't lost. It will also persist the VPD region across firmware updates, so this is all transparent to the user.

After installing the Custom coreboot / Full ROM Firmware, your device will boot directly in UEFI (or Legacy) Mode; ChromeOS will not boot (though it will try to do so and fail, until a new OS is installed). Your ChromeOS device is now a "regular PC," and you can install the OS of your choice without any special instructions.

Supported Devices: All SandyBridge, IvyBridge, Haswell, Broadwell, Baytrail, Braswell, and Skylake ChromeOS devices, plus the 2018/Kabylake Chromeboxes

Requires firmware write-protect disabled: YES

Notes -

I am finally giving the middle finger to Google googledevs with their firmware restrictions on Acer Chreomebook C720P

1. Removed firmware protection screw from motherboard.

2. Ran the mrchromebox script above making sure to backup the original firmware to usb disk, in case of unfortunate bricking.

3. Reboot - I now have a fully functional UEFI PC with no firmware restrictions.

3. Can run Arnoldthebat v72 or FydeOS 6.0 with Kernel 4.14.83... or efi ubuntu, arch linux, (which I could already with seabios) etc.

4. Can run all variants of chromefied eve, nocturne, etc with Kernel 4.14.83 & FydeOS 6.0 or ATB v72 as base...

Next step - use the internal SSD to dd my Chrome OS of choice.

I am happy like a piglet in mud :) ;)

Comment - this confirms that Google's firmware is crippleware to stop customers from updating their Chromebooks with unofficial ROMs
[Chromebooks] darethehair:
Background info: I own many ChromeOS devices (primarily used off eBay), including some older ones (Acer C720 and C720P), which -- as you know -- have expiring support in June 2019. In the meantime, I have plenty of experience running MrChromebox firmware enabling legacy dual-boot to my Linux-distro-of-choice -- either internally on a re-partitioned SSD, or an external USB stick. There is no great urgency to seeking out solutions to my soon-ending ChromeOS support, but your posts suggest that you are the 'expert' on the various options available for the C720P -- as noted in your post above.

Question: Have you considered the creation of an all-inclusive web page describing a C720P conversion -- not just the 'Full ROM/UEFI' change from MrChromebox, but everything else to get back an auto-update (?) ChromeOS with the latest features (Android/Linux) -- the stuff within #3 and #4 above?

You are welcome to give this a go - I do not have the expertise, or patience to set up an automated service of any sort, this is just a hobby to me, & owning a C720P, I just wanted it to be more useful to me despite the Acer & Google built in restrictions ;)

Windows 10 To Go on Acer Chromebook C720P

This might become a thread if needed...

Soon after I purchased Acer CB C720P (in July 2014)- tinkerer hobbyist that I was, I tried to get Windows 8.1 to run from its USB 3.0 on it -

Of course this is a modest machine, so it was expected that they will try & discourage this as Windows 8.1, then later 10 laptops are more expensive, & this is supposed to be a Chrome OS machine, so running Windows on it will be made hard with lack of drivers & the sort...

Anyways, with the help of a few hackers posted advice, I managed to get it working with most functionalities, especially the trackpad.

As I have a Windows To Go 10 USB 3.0 SSD lying around, & after flashing the C720P firmware, just for fun, I tried to boot from it on the C720P...

& all the answers with drivers & howtos are published by coolstar (saving me having to find them) -

https://coolstar.org/chromebook/windows-install.html?device=peppy

Surprisingly, it became very stable with the latest iteration of Windows 10, with most drivers working, apart from trackpad & screen touch...

I will try & get these to work, & if so, will publish results & cooking here, with links to drivers I scavenge too...

coolstar did the work - head on here for resources, howtos & drivers -

I want to get a large microsd card (256gb or larger) and access it through a OTG USB card reader.

Does an unrooted Pixel 2 have/need SDXC support to read the card or does this all fall on the USB adapter having SDXC support? I'm guessing this is the case, but I can't really nail anything definitive on that.

I ported a few codes into the Nokia Recorder app v8.1030.40 to enable support for OZO audio recording. I've only tested this in my Nokia 7 Plus, but it might work in other OZO-supported devices.

Changelog:

-

Added spatial recording support

: ACC recording format (screenshot 2) now records with spatial audio recording by default.

-

Changed app theme color

: just to differentiate it from the original base app.

NOTES: To make the most of the spatial recording feature, I forced Surround mode in this mod, which means all three microphones are used at once. Since this feature is for video recording by default, its full potential can be maximized in landscape mode (since the microphones are oriented vertically, putting the phone in landscape mode allows for differential left and right audio channels). Here, I forced the orientation such that the left audio channel is oriented at the top portion of the phone, and the right audio channel at the bottom. So for accurate audio channels, I recommend orienting the phone in landscape mode with the charging port on the right hand side (like recording a video). Of course if it doesn't matter to you that much, you can orient the phone however you like; audio quality is good, nevertheless. Enjoy recording audio in high quality!

I'm curious how you figured it out. Is there some Nokia API documentation somewhere or is it just a matter of enumerating device capabilities and trying the various options? Is is an Java API or do you need to call ioctl on some device?

[Nokia 7 Plus Themes, Apps, and Mods] markcoley:
I've been looking for some way of recording Ozo sound since I got my Nokia 8 over a year ago. Up until now I've had to record video as well using the camera app, then extract the audio in Audacity.

I had written to Nokia back in September 2018 and had this reply:

Hi Mark,

OZO Audio function on the Nokia 8 is only for native camera video recording function and not open to 3rd party applications. Please contact mobile phone division for any further questions and support.

Regards,

OZO Sales

I'd also written to the author of the Hi-Q app to see if he could get Ozo audio working, but he couldn't. The audio recorded by other apps had odd audio distortion present as if some algorithm was at play distorting everything.

I'll do some testing later!

You said you could configure the microphones. For the Nokia 8 it might be useful to use the bottom mic and the one on the screen side then you can leave the phone placed on a surface and still watch the recording.

Can you explain what you've done... I can let the Hi-Q app developer know!

Thanks,

Mark.
[Nokia 7 Plus Themes, Apps, and Mods] j€nish:
Yes my phone stock Nokia camera app
[Nokia 7 Plus Themes, Apps, and Mods] markcoley:
With further tests on my Nokia 8 I can see the microphone by the screen doesn't seem to influence any of the recordings. You can rub it or occlude it and the stereo field doesn't shift. If you rub the mic near the flash or near the USB socket you hear mono noise (equal in left and right) added to the recording. If you occlude either of these you get mono recordings and signal is equally split between left and right. If you occlude both mics everything goes very quiet and muffled. If sound reaches both mics then it successfully puts the recording in the stereo field. As rubbing sounds are noisy in one mic but probably not heard in the other the Ozo algorithm probably sends that equally to left and right channels as it can't tell where it is coming from. There is no audio distortion heard on recording music coming from a room TV. With my Hi-Q app, rubbing either of the same mics generates noise purely in the left or right channel. And that app still suffers from some very strange audio processing where music in the room seems to get signal processed away.

In short, this is the app we've all been waiting for!
[Nokia 7 Plus Themes, Apps, and Mods] webvan:
Thanks for your detailed feedback. Where is the "screen side" microphone located ? Based on the notes that came with the app "forced surround", shouldn't it also be used by the app like in the surround mode of the videos produced by the stock camera app ?

I videod a piano concert the other day and while the surround sound sounded better than the "front" option I was a bit annoyed by the "shifting" in the sound, probably due to the OZO software interpreting the sound sent by the mics.
[Nokia 7 Plus Themes, Apps, and Mods] markcoley:
The third mic is to the side of the ear piece, in the glass cutout line (on the Nokia 8).
[Nokia 7 Plus Themes, Apps, and Mods] webvan:
Ah ok, so not directly visible from the "outside".
[Nokia 7 Plus Themes, Apps, and Mods] markcoley:
More experiments! Using the in built camera app if you scratch each of the mics in turn with your finger whilst videoing you get a mono recording of the scratching. However the tonal quality varies. If on front or surround recording the front mic (by the flash) gives a sharp crisp scratch but the other two mics give a more muffled scratch. If on rear recording the mic by the earpiece inside the glass hole now gives the sharp scratch and the front and bottom mics give muffled scratches. On this new app the rear mic, by the glass screen, seems to do nothing and the front mic and bottom mic both give sharp scratching noises. Their behaviour is different from the camera app. Could it be they've been configured to record using the Ozo algorithm but with just two mic inputs? Interestingly if you rub one then the other in turn you get mono scratching but if you scratch both at once you get an interesting stereo mix! I've not tried headphones yet to see if you get the stereo noise of the old Nokia 808. Need to find my headphones!
[Nokia 7 Plus Themes, Apps, and Mods] Aleksey777z:
you are my friend genius, thank you! I was looking for a normal voice recorder for doc recordings with a guitar so long ago. Everywhere breaks zvaknk diode restrictions. And this app is good and your hands are golden.
[Nokia 7 Plus Themes, Apps, and Mods] LWTBP:
A BIG THANK YOU for doing this for the community. This completes the one thing I lacked in the Nokia 7 Plus.

There's one feature I request: When the recording is 'paused' instead of 'stopped', if I begin a WhatsApp recording, the Ozo recorder's recording stops completely and is saved automatically. Can this be prevented as regular audio recorders from the Play Store tend to keep their recordings 'paused' in the background even when WhatsApp recordings are created.
[Nokia 7 Plus Themes, Apps, and Mods] Liftedcorn:
If you would have properly read all of the above posts, you'd notice he said "NO FEATURES REQUEST" ??
[Nokia 7 Plus Themes, Apps, and Mods] LWTBP:
He said no request to add GCam support, which I totally understand. I am asking him to check if he can do something about a 'problem'. Is that wrong?
[Nokia 7 Plus Themes, Apps, and Mods] :
I don't think more than one app can access the same mic at the same time. Back when we had Oreo, call recording was possible, which was simultaneoes use of the microphone, but now it's pie.

We don't know what all has changed since Google revoked call recording.
[Nokia 7 Plus Themes, Apps, and Mods] alv3st3r:
Thanks a lot. Now I can finally record my covers in True Stereo. Would be great if you could rename the app package to display "Ozo Recorder" name in app drawer. Just a wishful thinking. Kudos to your efforts.
[Nokia 7 Plus Themes, Apps, and Mods] back.rider555:
Thanks for the tests, [MENTION=9836390]markcoley[/MENTION]. What is the orientation of the phone when you did the tests? I believe the differential use of mics is controlled by (1) the setting if Front, Rear, or Surround, and (2) orientation of the phone, either portrait or landscape. Whatever the orientation of the phone is when you start recording the video, that'd dictate the mics used. Here I forced phone orientation to 270 degrees so the earpiece mic is the left channel and so on. I only have Nokia 7 Plus, so I can't tell if the (forced) 3-mic stereo sound will be the same in other phones.

[Nokia 7 Plus Themes, Apps, and Mods] webvan:
Did a recording this morning using both the Nokia 8 and the old Nokia 808 and while the recorder worked fine on the N8 the result on the N808 is a lot nicer, much fuller sound. The mics are just not the same quality I suppose. I also have an old Nokia 830 that gave results that were pretty close to the Nokia 808. Bottom line is that if you want a good audio (or video) sound recorder get a cheap Nokia 830 ;) Oh and I stopped using my Zoom H1N, that's how good these old Nokia smartphones are for audio !

Hi [MENTION=8980633]back.rider555[/MENTION],

Great work! Thank you :)

As others have asked, please can you give more detail about what you did to get it working?

Or even better, if you can add to changes to an existing open source audio recorder app like... Audio Recorder for example (!) so that others can more easily test and add the other OZO audio devices, saving you some effort. And if/when you don't want to maintain it anymore then others can easily take it over. If you can it would be great.

Cheers :)

I last wrote a program in C many years ago so thought I'd see how Android works (!).
