problem chromebook 300e Bypass enrollment - Chromebooks

Hello chromebook 300e gen2 the bypass does not work has anyone found a solution please
here is what i have already tried
Make sure your Chromebook is off.
Unscrew your Chromebook back cover.
Unscrew the battery and unplug the power cord connecting the battery and the motherboard.
Open your Chromebook and press the power button for 30 seconds. This should bypass the admin block.
Place the battery back in and connect the power cords. Put the back cover on.
Turn your Chromebook on and press esc + refresh + power It may take 9-15 minutes to boot based on your device. Do not follow this step until you reach the chrome screen.
When you reach the "Chrome Os is missing or damaged" screen press Ctrl + d
It doesn't work for me

Have you found out how to solve this?

[Q] Disable power button long press = power off ?

Hi,
When doing a long-press on the power button of my Galaxy SII, after a few seconds, it powers off. This happens whether it is locked or not, and without asking for confirmation on the screen.
I'm using a Sena leather case, which presses on the power button. Each time I put it in the case, it powers off, then it restarts, and stays on "enter SIM pin code" screen. I may have discovered a new way to switch to Airplane mode but I'd like to avoid that.
Moreover, there is a distinction between :
- long press (2 seconds) : brings the power menu (Airplane / Reboot / Switch OFF)
- very long press (approx. 8 seconds) : switches the phone OFF
Also, these two keys are active even when the phone is locked.
Here's what I would like to do : disable both the 2 seconds press and the 8-seconds press when the phone is locked
I found some threads about key remapping applications or direct edit of keymap files, but none of them were successful.
Could someone point me out an application / a way to achieve that ? Does someone know if it's ever possible ?
(For now, the only workaround I found is a hardware one : disassemble the phone and sand the power button to reduce its height, so that it stays inside the casing)
Thank you in advance. Kind regards
My old HTC Hero used to do that too, which leads me to believe it is something hard-coded into Android itself. I'd suggest there is nothing much you can do, but wait and see if a dev replies or something.

I don't know if it's possible but if it is it has to be something in the kernel.
The 8 second power off function works the same way as the on on your PC and is used if your phone stops responding so I don't see a way to disable it with an app because it's ment to turn the phone off even if an app freezes your whole phone.
Hi,
If the 8-seconds press is hard-coded, I think precautions should have been taken to avoid unwanted power off each time you put the phone into a leather pouch !
On iPhone f/ex, you have to press both power and home button during several seconds to trigger hard reboot, which makes unwanted action hard to happen unexpectedly.
It's always frustrating to encounter such a basic problems on a $600 phone using the latest state-of-the-art technology, which powers off each time you put it into your pocket ;-)
I hoped some developer has found a way to workaround this. I googled a lot, but I didn't find anything.
So, if the power button features are hard-coded, the only solution may be to hard-remove the entire power button
Problem solved.
I disassembled the phone, I removed the power button, I carefully grinded it to reduce its height, and I put it back into the phone.
(For those who may already owned an iThing, disassembling a Galaxy SII is very easy, it's a matter of seconds with a good old mini-screwdriver; proceed carefully when grinding, because if you reduce the height too much, the buttom may break)
Now my power button height is just below the casing. It's still possible to press on it with a finger, but it does not press by itself when putting the phone into my leather pouch.
Thank you for explaining it I had an issue with my S II and it went to service to solve it, they totally changed the board and was shocked when I found the short press on power button doesn't show the power menu I used to have and it switched off immediately!
I've got to return it to service and your post made me thinking it's a simple issue! It won't take time
Regards,

[Q] Chinese tablet hangs after being fully booted, anyway to hard reset?

I've got a Chinese tablet that boots properly up to the unlock screen, where if I'm quick I can unlock, I can see wifi is connected, etc. but around that point it completely freeze, even the power button doesn't turn off the creen and I have to reset it by long pressing the power button.
I tried all combinations of keys to bring up a recovery (power + volumes) without luck so far. If I press any volume or back key while powering up, the tablet doesn't power up and stays black. adb isn't finding the tablet. I opened the tablet, there are pins to connect a rx/tx serial. I could do connect a serial adapter to it if that could be of any help.
Actually, at this point I don't care much about the tablet but that could be a good opportunity to start learning a bit more about Android hardware development, just don't know exactly where to start.
Any tip?

[Q] Xperia Tablet S (SGPT1211) not responding to reset/boot comands

Hello,
I think I might be at the end of the road with my tablet. I've never rooted it or tampered with it in an way, however yesterday it locked up so I did the usual soft reset (hold power and vol+ for 10 seconds) I then turned it back on and the sony logo popped up, but there it just hung. If I press and hold the power button it switches off, a brief press on the power button brings it back on in the same state. So I go Googling, including looking at threads on this site, all seemed to advise to try to get the Android recovery menu up. on the Sony this is done by holding the power and vol+ and then releasing the power button (only) when the son logo appears (this process to be started when the tablet is off) so I did this, and no response at all. Worse than that, where it would turn on and instantly hang, it now doesn't turn on at all. Hooking it up to my PC I can see the device in device manager, but it tells me my usb device has malfunctioned.
At the moment, my thoughts are to open it up, to:
1. Check that the power/volume buttons aren't stuck in some way (preventing the boot command being given correctly)
2. Remove and resolder if necessary internal battery to force a power cycle.
3. Bin it and get something new (it is 2.5yrs old so no big loss i suppose)
Any ideas where to look or similar experiences?
Thanks

HP chromebook 14 developer mode

Hi, I've literally searched anywhere and cannot find any answers but i have a HP chromebook 14 and wish to enter developer mode. It used to before but i had to powerwash with a failed linux install and when i hold escape + refresh + tap power it does nothing. if i hold power with the other 2 it logs out then another attempt shuts the system down. The escape key and refresh keys function alone.
is it possible there is a hardware problem where it wont accept all 3 combined? Bearing in mind i have tried an external keyboard and got the exact same result.
I've tried:
external keyboard
powerwash
all different channels of chrome (stable, beta and developer)
trying the key presses in every different combination from opening the lid etc
also refresh + power dosnt hard reset it just does the same as with escape being held down.
Could there be a software problem linked with the key presses? I really want some help because i find where i live now and the lack of wifi out and about unbearable to use this machine without some way to work offline and install to SSD
Thanks in advance if you can help
Turn on your chromebook and hold down ESC+refresh+power until it turns back on to a screen says "chrome os is missing or damaged" at this screen press Ctrl+D and press enter at the next screen it should turn on developer mode. This will take about 10 minutes or more depending on how much stuff you have on the Chromebook. After it finishes reboot and at the screen that says " is verification is off" press Ctrl+d and then you should be able to log into google.
can i do it with an hp 14 chromebook? the model is ak-039wm

bricked chinese tablet

i have this tablet which i think is bricked, it wont turn on even if i hold down volume up or down. when I connect it to the pc, after 30/60 seconds the com port appears (screenshot), after 1 second it disappears and continues like this. would anyone know what to do? flash a firmware? in the screenshots there are all the information of the motherboard
similar issues i had with my chinese tablets. The core issue i figured was that they don't hold charge any more and the battery drops like 20-40% with every restart. so the best way to get this up back is to put it on charge for few hours. then hold the vol up + power button, you should see the recovery mode/options page where when you press vol up button you can choose between 3 options of recovery, fastboot, normal. keep presessing vol up and go to normal and then press vol down to reboot into normal mode. if you have a different battery to replace, start there. Good Luck!
