Locked out of my Acer C720 - Chromebooks

SOLVED The problem was that dev_boot_legacy and dev_boot_usb had been disabled. Without getting into ChromeOS there seemed to be no way to set them until I found a guide titled "Workaround for battery discharge in dev-mode" (I cannot post links yet). It worked like a charm and I've just booted into Linux Mint off USB.
I've been running Linux on my Acer C720 since day one and I love it, but a recent series of events has left me locked out of it. I'd love to get it running again but I cannot figure out a way back in. I'll break down a short history and recent events.
Acquired C720 and unlocked developer mode.
Installed several flavors of Debian, completely removing ChromeOS from the SSD, eventually settling with Arch Linux.
After enjoying Arch for a year decide to try out Qubes.
Something fails during Qubes installation.
Boot into a Debian live environment from USB. Debian cannot see my SSD.
Try a few different distros from USB, but fdisk et al. cannot see my SSD.
Now I highly doubt that Qubes broke my SSD. It was probably already faulty but my Arch install was chugging along and not using the bad sectors. This is where I think I locked myself out, I don't remember the exact order of things but I re-enabled OS verification at the boot screen, and attempted to run the ChromeOS recovery from a USB. The ChromeOS recovery also failed. I put the SSD in my desktop and confirm that it was indeed dead.
So now I have a Chromebook with OS Verification enabled and no SSD to restore ChromeOS on. Bummer. But I figured I could try some things, so I booted into recovery mode with Esc-Refresh(f3)-Power and hit Ctrl+D at the Recovery Screen, success! I was able to disable OS Verification. But this has not solved my issue...
When I boot I can press Ctrl+D to be taken to a screen that tells me Chrome OS is missing or damaged and to insert a recovery USB. If I insert a USB loaded with Linux I am told "The device you inserted does not contain Chrome OS." I have no m.2 SSD to put into the chrome book to recover it and start the process from a virgin state.
What I'd like to do at this point is use the Chromebook running my OS from a USB stick, at least until I can afford a new SSD which will not be for some time. Is there any way for me to do this?

have you tried Chrubuntu?

I have, but I have no interest in keeping ChromeOS around. The problem is solved anyway.

[Q] GTab not recognized by PC at all

First, let me say that I've searched and searched and looked for all the info I can find about people having similar problems. I've yet to find anything that works for me, and I'm at my wit's end on this...
A few days ago I tried [unsuccessfully] to update CWM on a GTab. I can't get into recovery at all now (it just hangs), but this problem predates that.
The problem I have is that I cannot get any PC to recognize the GTab - in any mode - and I've tried 4 computers with various operating systems. I've tried Fedora, Ubuntu, Windows XP and Windows 7 and none of them will see the GTab at all. They won't see it with debugging on, with it off, in APX mode or anything.
I have gone through half a dozen cables and tried every USB port I've got. It just simply will not recognize the tablet in any way.
I'm toying with the possibility that the port might be damaged, but I can't think of a good reason why that would be the case. The tablet has been well taken care of, and all the other ports work just fine (audio, USB storage, SD).
So, has anybody else run into this issue and found a fix for it?

Read: Only ClockWork recovery on boot
Check dmesg to see if tablet is detected: A self inflicted wound
Also: [Q] (really) bricked g-tab.
If you can't boot the tablet at all--into either ROM or recovery--, then there's nothing you can do if your USB isn't working. If you can boot into one of them, then there's hope.
I managed to get CWM installed (was my bad on trying to flash the wrong one to upgrade it anyway). It's always booted just fine into the ROM, and everything works but the USB connection to PC.
I am actually a Linux admin by trade, so I kept an eye on all pertinent system logs and outputs when I tried it on the Linux box. No dice.

Well, you have to be careful about these things. APX mode, for instance, only "connects" to the host PC once, so if you unplug and replug hoping to see USB device recognition messages from the Linux kernel, then you will be disappointed.
What about on the gTablet? Does the kernel print anything pertinent when the cable is connected to the host PC (enable USB debugging first)? Are there any other error messages or diagnostics?
That's the troubling part. I'm finding absolutely nothing. Nothing at all to indicate there's any kind of issue. My guess at this point is that the USB port must be physically broken. I can't see any other way to make sense of it.
Here's one final suggestion: Open the gtab up and disconnect the battery. Wait 1 minute then reconnect the cable.
See if it helps. (It's for people who can't even boot the tablet into APX mode, but, try it before concluding that it is a HW problem).

Endless Boot Loop - Booting from USB

I'm trying to boot Remix OS Legacy version on a Dell Inspiron 1520 laptop, from a San Disk 16GB USB 3.0 drive. I've downloaded and burned the Remix OS to the USB twice but all I get is a Boot Loop.
The PC starts booting and I get the option to boot in Resident Mode or Guest Mode. Doesn't matter which I choose, it gets to the point in the screen shot below and the PC simply reboots over and over.
I've checked the BIOS and can't find anywhere to disable secure boot or anything like that. Any help or ideas Thanks!

When your pc starts, keep pressing F2 key. You will enter the BIOS menu. Go to the boot tab, select "Legacy Boot" mode and disable "Secure Boot". Change the boot structure from HDD to FDD. Press F10 to save and reboot. Done.

Ah, but you didn't say search harder. You just reiterated what I'd already been doing.

My nine year old ****ty laptop has legacy boot, dude, how is it possible you dont have it. If not, get an update from the motherboard's official website.
For example, some acer laptops did not have legacy boot mode, so, they released an update to it on their official website. Maybe, your manufacture did it too.

Well don't look anymore for secure boot because Inspirons don't have/support it.(Under system information mine says unsupported) I don't have any ideas/recommendations for you other than to redownload and reburn to usb because on my Inspiron all I had to do was change the boot priority order in the boot menu and whenever the usb is plugged in I boot to it.
I think Remix is still in alpha stage. From other side, there is to many diferent hardware, and it is hard to support all of them. My experience: I have Toshiba Satellite L775D AMD quad core wit AMD Radeon 6520G hd and 6GB RAM. I am very familiar with instalation of OSs on hdd, I have 4 Linux distros, 1 Android x86 and 1 Windows 10 on same hard drive (multi boot, runing GRUB from Arch Linux), but I can't boot Remix. Also, I can not boot Android x86 Lollipop and Android x86 Marsmellow. I can boot Android x86 KitKat and have one installed on hdd. From other side, on my wife Acer Aspire, I can boot all of these stuffs.
Sory dude, but I think you simple have no luck with your hardware and Remix. Maybe things will be better in future for you (and for me).

Same with me still, with beta
Workaround for dell inspiron is to use PlopKexec boot manager. Don't know if it will work for HDD but I got USB 32bit version working on my Dell inspiron 1545 using it.
32bit works for me!
Got an old Dell GX620. 64bit gave endless loop symptoms. 32bit works like a charm! :good:
My Toshiba Sattelite C50d-a-13w can boot remix and android x86(_64) from 5.1 to 7.1 ...................
I realize that this is way overdue, however Dell laptops back then did not support secure boot, and while they did support both UEFI, you could not enable or disable either, you just had to manually specify each time you boot from USB what you wish to boot (and Dells use F12 for manual boot).
As to whether RemixOS boots or not, that is down to the specific hardware and OS version.
I have an Intel DH55HC motherboard, and Remix OS booted on it without issues, until the last versions, where it would keep failing to boot.

Wisky 3G068i 9,7" w8.1bing->w10 fail. Error message, cannot continue. unusable.Urgent

Wisky 3G068i 9,7" w8.1bing->w10 fail. Error message, cannot continue. unusable.Urgent
Hey,
I got Wisky 3G068i 9,7" w8.1bing tablet yesterday.
It was reset to factory settings. After getting things going, it worked fine with win8.1 and updated itself. Then asked do I want to update to win 10 and after reading and ppl saying its better(and i dont really like win 8) I updated it throught windows own update screen.
After night of installing it, it was stuck on 95% (took hellish long time) and had error message on it "please install extrenal removable media and press ok" (its in finnish so translation might not be correct but you get the point)
I tried clicking yes, no affect. Then removed card, put it back in and it started to revert itself back to win 8.1 after saying not enough room or some error(cant remember correct anymore).
It reverted approx 8 hours then that error came again and now its stuck on it, it wont do anything.
I tried to create win10 install to micro SD with win10 media creation tool but it wont boot from it. It boots up, wisky logo is seen and then rolls loading dot for while, then flashes some screen like command screen, very fast, I cant read what its doing and the error is back.
What can I do? there must be some way to get to reinstall of windows 8.1bing or win10 but how? I dont know does tablets have bios or how to get to it, or how do even get it to boot up some install media.
Been googling another 8 hour but i just cannot find anything that would help my situation.
How can I force it to boot from microSD or do I need to get some microusb-female usb adapter for usb stick? I have a USB hub and throught it i was able to install the win10 installation to usb stick and microsd but idk does the tablet understand that hub(and read from it the usb stick)
i have years of experience with pc's but with tablets i dont really have any.
Tablet has 3 puttons: power on/off and volume up/down
Since I dont have manual, i dont know how to do any resets on it or anything and seller did not have one and maker is chinese and hasnt answered me.
I found old posts on internet saying ppl did get the win10 to install but none posted how they did it.
tablet has:
2gb ram
16gb harddrive
microSD port where I have 64Gb brand new Kingston class10(it works even it says on specs 32gb is biggest)
3.5mm port and micro HDMI port.
Please any help is useful and Im forever gracious to whomever can help me fix it! heck i even buy you a beer if possible

Fastboot can find Waldo faster than it'll ever find my phone.

Please don't drop the "wrong thread" bomb on me. My experience in forums is, you ask a question and you get 50% told to reboot, 40% told you're in the wrong thread, 9.9% other nonsensical things, and the 0.1% would be an actual attempt at a solution.
Here's the thing. My v10 is not going to have its bootloader locked by running fastboot. I have tried every single solution. No matter what, the computer never sees my phone on fastboot. All the drivers are right, re-installed nearly twenty times now too. I've tried the light, minimal version of adb. The full version. That other version I didn't quite get why it was different. And in all permutations with all driver installation attempts.
Don't know if this has anything to do with anything, but the phone has never once successfully booted into recovery by holding down power and down-volume. Nor power and up-volume. Not once. I have only ever been able to get it to do so with the "adb reboot recovery" command, just as, before I installed the xPosed module, "Quick Boot," there was no way I could get into bootloader other than "adb reboot bootloader" command. Because of course bootloader sees the phone in all states except fastboot.
No, if I plug it in while on bootloader, nothing happens on the computer. Nothing installs. No little yellow triangle thingie shows up suddenly in my computer's Device Manager. Ever. So there's no way to make the driver upgrade to whatever it needs.
Only one time has "fastboot devices" ever shown this device, and that was the moment I unlocked it to root it in the first place.
And now that this device has proven to be without a doubt the worst thing I've ever, ever owned, and I am sick to death of all its problems and screw-ups, I have absolutely no way whatsoever to relock the bootloader and do something to exchange it. Unless anybody knows any other way for me to do this without the use of my computer. Anybody? Please help. I can't even stand looking at this phone any more, much less use it without it making me want to kill puppies and babies and throw exploding Samsung 7s at little old ladies just to watch them burn.
All help is appreciated. Except, as I said, what I usually get 99.9% of the time from forums. Thanks.
Oh, wait, mandatory emoji storm... sorry, almost forgot: :cyclops::good::silly::laugh:
Oh, before anything, I forgot to add...
I tried every USB port, with multiple USB wires, on both computers, one old and one new, one Windows 7 and one Windows 10, and again, in all permutations. There is no possible way this should be this frickin' difficult.

Had the same problem. I highly suggest if you have even a 16gb flash drive to download and install Ubuntu onto it. It takes just a few minutes to get setup and fastboot will detect your device almost immediately. Launch Ubuntu in live boot (from the usb drive) and you can then try it out and it should work fine. This was the only option that worked for me after trying just about every option online I could find.
Once on Ubuntu right-click the desktop and open Terminal and put in the following without quotes around it: "sudo apt-get install android-tools-adb android-tools-fastboot" follow the prompt and within a few seconds you should be able to issue both adb and fastboot commands properly.

Sounds like something totally new for me to learn, but I do have a pretty good size flashdrive. So, here goes something. I'll report back how it works. I'm glad to hear there's at least something to try because as you no doubt saw from my tone, I really felt like I'd been totally Kobiyashi Maru'ed here.
Because technology hates me in every way, I cannot get Ubuntu to work at all. I give up. I'm gonna go ahead with that puppy-kicking plan. I am just DONE.
Don't know much about fastboot and all that stuff, mainly because I have Verizon VS990 version with bootloader that can't be unlocked.
Having said that with Windows 7 or 10 did you install and open all that fastboot stuff as administrator? Because if you didn't do all the required steps as administrator that might cause this to not work on Windows.

Sir, if you came up with the answer to this (and that means me taking the time tomorrow to try it again) you will forever have me bowing down to you in the most embarrassing way imaginable. I'll letcha know how this goes.
Nope. Nothing. If I touch it, it refuses to work. I tried to make an Ubuntu boot stick, but every effort to do so gave me nothing but errors so I don't even know if that would work. Meanwhile the phone only gets worse, and I'm stuck with it, and out $600, and there's nothing that can be done. This is without a doubt the worst. And I am so f#$^%&^ing done with technology right now, you have no idea.

HDX 7 TWRP, no os, no ADB access [Lineage OS]

Ok, I need to load an OS back to the device ( wiped data/system because girlfriend enabled encryption.....) anyway I've tried the same computer I rooted the thing 2 years ago, installed new drivers and also am in test mode, however
the hdx (when booted into TWRP) never shows up in device manager, and "adb devices" is always empty. I've tried several USB cables, and even a mac computer, anyone lose access to their device and got it back? Any hints?

First verify drivers are working. For whatever reason legacy composite drivers from Motorola seem to work best with this device regardless of platform or host OS. Install the Motorola Device Manager from this page and then switch drivers. No need to launch the utility.
TWRP must be at v2.7 or above for ADB support. If below 2.8.6.0 you should consider updating via fastboot assuming bootloader has been unlocked. See: https://forum.xda-developers.com/kindle-fire-hdx/development/recovery-twrp-3-0-0-0-t3322547
If still no joy you will have to erase/replace aboot and rebuild the device from scratch. Data loss is likely.
hmm yeah, the main problem seems to be the tablet never shows up in device manager as any device... thanks for the hints though, will try the motorola device manager drivers...

Where'd you get the drivers from? Can you share a link to the ones you installed on your PC? In control panel devices have you tried enabling show hidden devices to see if the tablet is detected but not enabled? What version of Windows?
I haven't tried this yet personally yet but I'm wondering if a live Linux (e.g. Mint) booted on USB thumb drive might be an option. I don't know enough about using a Mac to access the Kindle to offer much in detail there. Have you tried different USB ports on each of these computers? Do other USB devices show up okay?

Read here literally two posts above yours. Where was Linux/Mac ever mentioned? Connectivity on Windows almost always boils down to procedures, drivers and/or USB cable integrity. Assuming the device itself is not toast.

Oh snap, this is a good idea - will try when I get home.
TWRP 3.1.1-1, Win 10 64bit - yeah tested several usb ports on my computer - I originally rooted the HDX with this computer and windows 10 install about 2 years ago [side note do you guys remember reformatting every 6 months because windows was such a pos, I'm really glad those days are long gone!]
LOL yep Windows 10 nowadays does seem a lot more stable than the earlier stuff.

Hi Davey oops somehow I missed that you had already replied a few days ago . cq_ did mention a Mac computer. I suggested testing with a live Linux thumb drive boot in case they have an extra thumb drive kicking around to find out what that OS sees as compared to the Windows and Mac already tried. When reviving my Thor, part of the process I tried was draxie's 1-click, which required Linux and access to the device to do its work, so it seemed like a good to me to try to boot the PC that cq_ is using into Linux. In my case I have Linux Mint installed on a separate SATA hard drive but not everybody has that type of rig, hence the live Linux USB thumb drive boot suggestion.

Fair enough; I may have been a bit harsh in my response. I now see the passing reference to an Apple rig and appreciate the unfiltered perspective often obtained via Linux. That said, there is new info on the table that suggests the OP has access to a Win10x64 box which should connect effortlessly/reliably with Moto drivers and a quality USB cable. Mucking with drivers can be a PiTA on Windows; the Moto variants remove much of the pain - although you still have to select the proper driver after tethering in the target mode (adb or fastboot) as Windows will typically default to Microsoft/stock variants which rarely work with HDX devices.
