Hi,
So I have 2 Captivates here with me, one is running on AOKP Milestone 6, and is recognized just fine by the PC, so we can rule out drivers issues
On the other hand the other captivate had eclair, so I got into download mode, and used a one click Odin package to KK4, after that I can't get in anyway to Download mode, I nevertheless can go into stock recovery. I should note too, that I have a jig that is working with captivate1 but not with captivate2, like I said, it is not going into download mode, screen stays black.
Whenever I try to get it connected to the PC, a pop up on the PC says (roughly translated): "that one of the USB devices linked to the computer ididn't worked correctly and Windows couldn't recognize it. click on this message to get more info on how to solve this problem".
After I click on it, a windows with the title " USB device not recognized" is shown and listed is what I know is supposed to be my captivate but instead it says "unknown device".
If I insert the battery the device would turn on, no need to press the power on button, but if I shut down the device, I can't turn it on with with the power on switch, I have to reinsert the battery, in other words it's like the power on button is stuck, I don't know how to verify this, and I don´t know if this is what is causing me the problems, though I dont think so. Power on behaves just fine inside recovery or with the device turned on.
I can charge the device with the PC or with wall charger just fine.
Thanks
Probably the power button as you suspect... They have problems with the power button, so I have heard.
But what about the usb not being recognized, and I should also add, that it intermitently gets recogonized and when it does, it gives the message I typed on the OP. Could the power button affect to this extent?
Is there anything that can be flashed from 3e recovery (from KK4 update)??
Nope. Stock recovery is very constrictive.
My power button stopped working a couple days ago but I was still able to wake device with volume buttons. I was worried that if my phone were to shut off I wouldn't be able to turn it back on so I booted into bootloader and was going to try and flash "oem off-mode-charge 0" (which should then make the phone power on when plugged into charger).
At the time I couldn't detect the device using fastboot and as I was searching around on my computer the screen on the phone turned off (was in bootloader at the time). I'm not sure at this point if my phone was on and that both the power and volume buttons were not waking device or if the phone turned itself off.
I have tried the hold the volume down and plug the charger in trick to try and get back into bootloader but nothing happens. When I plug phone into my computer it takes about 20 seconds but I get the little windows ding that something has been connected but phone is still not responsive. I'm starting to think I'm a little screwed here but welcome any input.
You just looking to get the screen to light up so you can implement a way to use the device without the power button? You could try gravity screen or something but first things first...
If its not lighting up on plugin have you tried connecting to a computer and opening ADB and issuing the command adb devices followed with adb reboot. If you wanna go back to bootloader just adb reboot-bootloader. That will restart device so screen is back on and I would turn on the Ambient Display mode so when you pick it up the screen comes on or get a volume power button app or gravity screen app that turns on when you take it out of pocket. Thats all I can suggest and hope any of this helps.
With phone plugged into computer, nothing shows up when I check adb devices or fastboot devices. I guess I'm unsure on what state my phone is in. None of the buttons do anything and nothing happens when I plug my phone into my wall charger (no charge light or screen on). The only response I can get is when I plug the phone into my computer windows makes a noise.
Anyone know what happens when a powered off phone gets plugged into the computer? Does windows make the little noise indicating a device has been plugged in even with it off?
It does not make a noise if its off.. That much I know. Interesting though. Are you sure you have the correct drivers installed for your nexus phone if you are on windows. Go into hardware manager by right clicking on my computer and make sure that its reading it correctly in usb devices without a yellow triangle next to it.
I should have the correct drivers. I just went ahead and reinstalled them through the nexus toolkit. In device manager it says: unknown USB device (device descriptor request failed).
I checked adb devices before all this happened and it displayed correctly. I then rebooted into the bootloader but the fastboot devices command did not show anything. It was shortly after that that the screen turned off. Will the screen normally time out when in the bootloader? I'm wondering if my phone is still in the bootloader with the screen off and both power and volume buttons non functional.
Only thing I can think of is to wait for it to die, then volume down + plug in to pc and when bootloader screen appears issue command fastboot continue and it should boot up. Then get something to remap key or an app. If this all fails after it dies and you restart it assuming debugging wasnt on or its just reading phone as media device of sorts not allowing adb then you may have to get the power button assembly possibly and install it yourself or open the back case and hit the power contact under the button and see if you can get it on. Thats all the ideas I have.
I'd also suggest that after you reinstalled drivers make sure you did a reboot and then plug in the device and also try using a different USB port and or USB cord also as odd as that sounds Ive seen it work before. Im pretty tapped on ideas tho. Do you know if you had usb debugging enabled?

Ok, cool. I'll take a look.
Managed to get it back into the bootloader this morning. So I guess this is a PSA, if your screen times out while in the bootloader, the volume keys will not wake device so since my power button is broken I couldn't wake it. At that point, the phone is in a state where it cannot receive any fastboot commands, even though it is in bootloader with the screen off. What I had to do was wait overnight for the battery to drain and have the phone power itself off. At this point the volume down plus plug in charger trick worked to get it back into the bootloader with screen on. At that point I was able to 'fastboot reboot' back into system.
Thanks for the insight people

It's easy but also annoying. Removing the 18 screws is the most annoying part

Driver issue.
Remove/uninstall the drivers from your PC when the phone is connected.
After that reinstall the adb/fastboot drivers.
N6 - Power mapped to VOL DOWN; turned off and can't get it back on
Hi all, I had to remap my power button - I mapped it to VOLUME DOWN. The other day I voluntarily powered down my N6 at a test center.....and haven't been able to get it to respond since. I do have a Pixel 2 XL on the way - but not that sure I'll want to keep it. The N6 is so sweet.
I've tried holding the volume buttons (POWER and VOLUME UP) for like a minute, but nothing. When I charge it, I see the battery symbol (full) but only for about 5 seconds.
ADB does not see any connected devices. Wug's NRT does not see any connected devices. I'm at a loss and afraid that I've lost my N6 and will have to use the Pixel 2 XL regardless what I think about it.
Any other ideas?

Wow - just got my N6 to boot using this little tip I found on Reddit - https://www.reddit.com/r/AndroidQue...ny_way_to_turn_on_phone_without_power_button/
I was holding down the Vol Up and Power buttons (which are both the Volume bar since I remapped my power to Vol Down), but I hit 'enter' on the 'fastboot continue' text in the CMD prompt just after I plugged in the USB and the battery icon came up. It booted into bootloader mode briefly first, then went into system reboot. Whew!
I think your button assembly is broken and I would replace it. You could try the work around in Broken power button, any way to boot? by altarity, post #3.

My HTC Desire 510 from EE in the UK will not reboot after I used the shutdown menu to select 're-start'. It is just a dark screen. Cannot even do a hard reset with 'power-on' and 'volume down' buttons. I have tried taking out the battery, and then doing a hard reset and again nothing. I have left it charging overnight with the original HTC charger and again nothing. None of the charging lights come on either.
I have tried to plug it into the Windows 7 PC with the USB cable and it looks like it is intermittently 'seeing' the HTC but saying the 'device is not recognised' but then the unrecognised device disappears from the Windows USB ports and then again a few seconds later get a 'device not recognised' message with the unknown USB device briefly visible and then it disappears again.
Have not made any modification to the OS since getting it from EE/HTC apart from installing apps and updates. The phone has not been dropped, or got wet or in any other way physically damaged and was working fine.
Any advice/help would be very much appreciated.
HTC One M7 - Screen connector on motherboard is destroyed. Phone is fully encrypted but I have the password. Was trying to follow guide on stackoverflow "Mount Android encrypted data partition on PC" to recover data however I cannot get adb devices or fastboot devices to recognize my device.
When I plug in the device the red charging light comes on.
If I hit the power button the charging light turns off and the vibration motor spins.
If I hold volume down and power button the charging light turns off and the vibration motor does not spin (assuming this is boot loader).
I can't seem to get the phone to enter fastboot mode? I have HTC Sync latest installed on my PC.
Any suggestions?
I managed to solve it!
simple!
hold down and power for it to restart, at the exact moment when it restarts, you press the two volumes, up and down, and connect the usb cable right after, before turning on, then a menu appears where you can hold up for 7 seconds and unlock the bootload
what does the exact moment mean? And it connect the usb cable for odin?
