Stupid stupid mistake!

I think I have fried my Nexus 7.... didn't even think about what I did how stupid am I....
I decided to wire up a Hella connector to a USB cable the idea being to plug it into my phone for charging on the road... I then had a not so smart idea to use my OTG cable to connect the USB A connector to my Nexus 7 to see if it worked...
Nexus 7 booted past the bootloader and then nothing.... I realised then how stupid I had just been...and still nothing...
Presumably I've run a shed load of power down one of the data line..... what a fool.....
ARGH!!!!!!! anything I can possibly do to salvage it.... please!! :crying::crying::crying:

you could try something ASUS support told me, press all buttons (volume + & -, power) for 30 seconds, and if it won't boot after that, you should get a RMA

Going the RMA route would be costly. If it is dead, he'd be better off just bring a new N7.

Thanks for the suggestion but no it hasn't worked...
I've had the N7 plugged into the charger for the last 30 minutes or so and when I went back to it the screen backlight was on slightly (you can see if you look at the screen from the side)... but the whole unit was really really hot... I've obviously disconnected it but now can't get the thing to turn off, if I hold down the power button the screen flicks off but then back on.

I would think that "broken display” units on eBay/CL probably have working mobos and batteries, as the owners are trying to dump them because of the broken screen. But, buying used is a crap shoot.
Nice that Google is selling N7s at cost (or even a loss) - but it does mean that any oem component replacements will be a significant fraction of the original price.

I was reading in Play Books when my N7 shut down due to low battery. I plugged it in and it wouldn't charge or boot and I noticed a faint light bleed and faint dots streaming from right to left on the display. I tried things like holding the power button for 30 seconds to reset, holding vol down and power to try to get to recovery, but it wouldn't take. Finally, with it plugged in, I held down the power button for just about 10 seconds and backlight and dots stopped. A few seconds later without pressing anything, it booted up. It would start to charge, but if the screen timed out, I was back to the earlier state and it wouldn't come on. So I got it started again and immediately went to developer options and checked Stay Awake while plugged in. Eventually the charge built up and I'm back to normal, at least my N7 is normal. I only mention this because the OP talked about the faint backlight and it may be worth trying.

A standard hella charger outputs 5V at 2A which is the same as your N7 original wall charger.
I doubt your problem came from the charger, it might be softbrick at an unfortunately moment.
I came across a similar problem when i was editing a custom kernel.
If you tried every method to shut down the device and failed do the following:
1. Open the case (it's quite easy to open with a plastic card)
http://www.ifixit.com/Guide/Installing+Nexus+7+Battery/9895/1
2. Unplug the battery and hold the power button 30 seconds (with the battery detached)
3. Let it soak for 10 minutes
4. Reconnect the battery and close the lid.
5. Put your nexus 7 in the wall charger, and you should see the battery bar on the screen.
After that, let it charge a few minutes and boot the device.

[Q] Sprint Galaxy S5 Not Powering On

Can someone please give me some advice on what to do. My phone is less than 3 months old and will not power on. It doesn't do anything, not even the vibration it usually does. I've tried plugging it into the charger but it doesn't even have the charging light on. It was working fine and just stopped. I pulled the battery out and put it back in but nothing it working. If If anyone has any suggestions, I would be very grateful! Thanks!!!

what were you doing at the time
What were you doing at the time the phone stopped working? Did you try charging the battery on an external charger?

As the poster above suggested, what were you doing recently? We are looking for clues as to what happened? Did you yank on the power cord, drop the phone, et cetera?
Make sure that your battery isn't in backwards in the phone and try using a different cable to charge the phone. If it still doesn't charge, then borrow a friends external charger.. or even the (charged) battery out of their S5 for a few seconds to see if your phone will turn on. We're trying to differentiate between a dead battery and all other problems.
If you still have no luck, then remove the battery for ten seconds, then replace (the presumably charged) battery in your phone. Then press and hold the volume down key. Then also press and hold the home key, then the power key. After about five seconds, you should see the phone start to the "download screen". If so, post here for further guidance.
If you phone is non responsive to a borrowed battery and the download mode described above, then you should seek warranty service with your carrier. A three month old phone should still be under warranty.

I was talking on it and hung up. Then, I tried to use it about 5 mins later and it wouldnt turn back on. What do you mean by "external charger"?? Sry, I'm not very tech savy lol! The only charger I have is the one that came with my phone. Thank you for replying! ☺

My battery was charged in the 70% and I also used my husbands battery (we have the same phone) but that didnt work either. I'm going to try your other suggestion. Thanks!

Can you get into recovery ( volume up + menu +power button) or download mode (volume down + menu + power button)?
You may read this article http://www.technobezz.com/samsung-galaxy-s5-not-charging/, hope it helps.

I tried the volume down + home + power and it didn't work. I'm not sure what to do. I don't want to make a trip to the store but it's looking like I'm going to have to.

It may well be an electrical hardware issue, it doesn`t look like a software problem to me. Good luck and i hope its fixed soon

It is looking like a hardware issue. If you are positive that the battery is charged.. i.e. if the battery turns your husband's phone on, then we ask what is different about your phone? Most software issues would be bypassed by starting a phone in download mode, which is why I asked you to try that.
Have a quick look at the battery "fingers" or pins on your phone. Those are the gold or silver coloured pins that line up with the gold or silver tabs on the end of your battery. Do they all appear to be the same? There isn't one that is bent out of alignment or shorter than the others where it might not be making contact with the battery?
And why not try one more test? See if the phone will start up in "recovery mode" this time.
Pull the battery out of the phone for ten seconds. Then replace it. Now in order.. press and hold the volume up button, then press and hold the home button as well. And last, press and hold the power button. Continue holding all three for ten seconds or until you see the phone screen turn on.
If that still doesn't work, my best guess is that you may have accidentally banged and damaged the power button. If it was me.. I'd try pressing really hard and wiggling the power button for a few seconds to see if you can cajole the phone to power on at least once and confirm the problem.
But that is about all that we can do. If you can't get the phone to power up with a known good battery.. then th store needs to check it with test equipment to narrow down what the hardware fault is.

Power Cycling

So my new Galaxy S7 is power-cycling in to recovery mode but the boot won't complete. The battery is completely dead and while charging it continuously tries to power on in to recovery mode. I can't get it to do anything else. Buttons aren't jammed. Any ideas? I've scoured Google but nothing has come up so I figured I'd rely on Good ol'e XDA!

Sounds like a hardware failure. That's what warranties are for. Take it back to Sprint for a replacement.

Did you take the phone in for service? What did they do to fix it, if they fixed it... I have a dead phone and need some answers if they are out there. I'm looking through every post that has anything to do with this subject and coming up blank - just like my phone's screen!
Part of my issue is that I had a shut down from out of nowhere on NYE. I was able to bring it back up with the power, volume up, and Bixby combo the next day. Foolishly I assumed it was a fluke and went right back to using my phone just as I had before. I saw an article about disabling the Bixby button, which seemed to be the thing to do... When the phone shut down the next day again, I couldn't bring it back because I no longer have a Bixby button for the combo. It's been down since Jan. 2, and I'm at my wit's end. Can you please update your phone status? I'd appreciate it if you can!

Lol disabling the bixby button in software does not mean you can't trigger download mode. That level of software has no idea what packages you disabled ?

Did you have Substratum themes applied before updating?

Happened with me last night, bunch of updates and then black. I was gonna send to warranty, then someone told me Power + Bixby + Vl down and it worked. How can I find out what did it

When I called Samsung, they were clueless how to get it started again as we walked through all the button combinations they had. It was fully charged when it stopped working, both times. The second time it took me a few days of trying on my own, calling, Samsung and then going into their repair store.
They took it back to work on it after I explained what was going on. He tried several things and came out and told me it may need a replacement but wanted to try one more thing. Hours later, he came back and said he hooked it up to a charger and it had been dead. Once it started charging, it showed the green battery, lightning bolt and blinking circle. It still didn't start normally, but the three button combo worked at around 20%. I'm not sure if he tried before that, but it came back on.
I've discovered that my handset is extremely sensitive to cold temperatures and shuts down. I'm in the Midwest and have been working outside in a tent like structure. I listen to music, books, or podcasts while I'm working. Many times, I will put my phone on a shelf while charging but still listening. The phone shuts off and first I have to wait for it to warm up, then it has to drain the fully charged battery, and then I start charging it again. After the first time on my own, I did the button combo right after it started taking a charge and it worked.
I'm not sure if a replacement phone is the way to go, because if this is common on the S8, I might end up with another dud that would just frustrate me more. I like the phone, but this quirk is annoying.

Last night my phone was charging and accessible fine. This morning I have a green light at the top showing I assume that it's charged but the screen is totaly black. nothing I do brings up any screen. I tried all the button combos I tried plugging it in to the charger and nothing shows any kind of reaction. I tried plugging it into my computer and the computer said it was setting up device QUSB_BULK. Then said it was set up but even after it supposedly complete I could not find the device. What the hell?

S8 Black Screen
Is the green light staying on? This happened to me on one of the many shut down times I experienced. I think I narrowed it down to my phone not liking cold temperatures, but I don't know if that is your phone's issue. It hasn't happened since last winter, so I haven't needed to do any of this for quite some time, but I'm trying to remember all of the steps I took.
I'm gonna suggest getting the battery drained back down to zero. In order to drain the battery when it's black screened, I kept trying all the button combos repeatedly for, it seems like, maybe three or more days... I couldn't tell if it was dead on several of the occasions, but when I had an indication light, it went off after days of doing any and all button combos, just to drain what battery I could.
Once you do that, while keeping it out of any extreme temps, (if there have been any) then plug in the adapter that came with it, using a good quality USB-C cord and charge it again and see if the charging screen comes up. (The Fast Adapter Charger that connects with USB 3.o is the best to use. Samsung wanted me to use the original cord, but I have no idea where that is! I just used a good quality cord.)
If that doesn't do the trick, then it's not the same issue I had, and I wish you luck on finding out and getting it fixed! Don't forget to update the site for others to find out if your tricks work... (You can still try this, but it may be just to rule it out as a possibility.) Try draining it more than you first did, and then plug it in again to see if it takes a change.
If it is taking a charge again after draining and plugging in your power cord, wait until you get back up to at least 20% and then try the three button start (Bixby / Power / Volume Up at the same time) and make sure you hold them for up to 30 seconds or until it kicks on. One time, I think I held it for almost a full minute. But it did take the change, restarted on the three button combo restart, and didn't have any new issues from its down time.
If this works for you, come back and tell us! If not, come back and report what you try and what the results are.
I really hope that helps! Good luck!

Sounds like a system problem, you can try to use the button to force a reboot, if there is no response, you can try to reinstall the system, if this still can not be solved, then you may need to replace the new screen, you can go to Witrigs to see Note 8 screen, they There is an original Note 8 Super AMoled screen for sale. The price is also relatively low.

PH-1 requires long press PWR button to boot - Any ideas why?

Hello,
I just purchased a used PH-1 and it was reset before I got it. So I put in my Google credentials and restored a backup no problem. The first few times I powered the phone down and plugged in a charger, I saw the battery charging graphic icon (looks like a coffee to go cup : ), no problem. But now, when I power down the phone, the screen is black and stays black with no sound or vibration when I plug in the charger. It still *does* charge in this state, but when I try and boot the phone back up, I have to press the Power button for 10+ seconds and let go before it will boot. I suppose I can continue to use the phone this way, but I was wondering if there was a reason and/or fix for this that anyone is aware of? thanks so much.

Sorry I should have mentioned, I tried several cables and chargers... same result.

Another issue I noticed. If I turn on the phone when it's plugged in, it goes to the bootloader (which is locked). I have to unplug the phone if I want to boot to the OS.

Make sure you're not fat-fingering the volume down button and the power button, because that combination is guaranteed to get you into the bootloader.
