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

I was in TWRP recovery flashing Xron rom b2.9 and the recovery said the zip file cant open. So it just kept doing its thing and would not let me go back to the main menu. I tried hitting home and back buttons, but no luck.
This was not found by me. I am giving credit to this amazing person who somehow found a trick to reboot the device even if your not in an OS.
"The reboot solution that I found to work all the time is to simultaneously hold the power button, volume down button and the big HP button for 30 seconds."

I had an issue with my Touchpad where the touchscreen stopped responding in CM7. Volume rocker worked and power button would turn the screen on and off, but I was stuck with no touchscreen and no means to reboot. After a mild panic attack, I plugged it into my computer and luckily had debug mode enabled so I was able to adb reboot it.
But this... this is incredibly useful. Thank you for the post. I'm glad to see that the manufacturers making devices without removable batteries are giving us a trump card to hard reset the devices. My 7" Galaxy Tab has a similar function where holding the power button down for long enough eventually resets the device.
..or you can just hold power + card button for 6 seconds. no volume button needed.
Hi,
i recently bought 2 Galaxy S wifi 5.0 as there was a deal going. first one worked fine but a few days later and i've opened up the second one to find the screen isnt working.
its stuck at the 'select locale' screen from the initial setup with me unable to scroll and select any options. the back and menu keys don't work either although the home button seems to be doing something as the keys light up when pressed and it also works in recovery mode.
The volume key works as i can see the media volume going up and down when its pressed, it also worked when i booted into recovery mode to try a factory reset.
i can see the media scanning running after bootup and when i plug in the usb to a computer it appears with the USB connected (but ofc i cant press the button) so i think the system is running fine?
the power button seems a bit stickier than the one thats working fine and also when i hold the power button in to shut down the device (unable to press power off) it comes straight back on. is there way to force a shutdown rather than reboot?
just wandering if theres anything i can do to hard reset? im a bit reluctant to flash a stock rom / gingerbread as i have on the other one if the screen is just dead but thought id see if anyone had any ideas of anything i can try?
cheers,
Well, I would return it since it is still under 30 days (where did you get it?).
comet was £99.
yeh ill probs take it in tomorrow just wandered if there was anything i could do to double check the screen was definitely goosed
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?
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
Hope you guys can help me out, to cut the long story short, I've an old tablet, of which I've forgotten the pattern on and best of all, I've forgotten the email too!
I tried connecting it with my laptop (running Windows 8.1). It only detects as charging cable and from what I've read, I think USB debugging is set to "off" and I can't go to settings and enable it.
I've tried the volume up + power button boot option, it opens the said menu, I select" Recovery mood" the little android bot comes that it's initializing system, etc, and then after few seconds, another animation comes with green android dead with red triangle exclamation mark, written "Error" below only. I tried doing "volume + power" didn't worked.
I've exhausted almost all my options here, any help would be much appreciated.
It's an ASUS tablet.
Thanks
