Hi there, ive had my nexus for around 6 months now and it started acting up a few days ago to the point where it refuses to boot. When i got the nexus, it shipped with 4.2 and i updated to 4.2.2. I then used the toolkit by wugfresh to prepare for custom roms. It was working great on paranoid android, i updated as new versions came out. I was on the latest build (3.98) with M kernel, and a few days ago it started switching off without reason. It wouldn't boot unless i plugged a cable in, then on friday, i found my nexus stuck in a reboot but it wouldn't get past the PA boot logo. I booted into TWRP and tried wiping caches, no luck. I then tried a reinstall of PA and PA gapps. Still no boot. I have taken a backup, done system, data and caches wipe and reinstalled PA again and still no boot. The nexus was also refusing to switch on at some times, even though it had plenty of charge. Now i cannot get it to boot up. I still have access to TWRP.
Can anyone suggest actions to take? I thought my battery cable/connector might be loose, but i couldnt get the back off to look.
Thanks, donk165

Have you tried following the flashing a factory ROM/return to stock sticky at the top? It essentially wipes everything and makes it like the day it came out of the box.
EDIT: there are numerous videos and walkthroughs on YouTube and here on the forum, just do a search, on removing the back cover.

Thanks for your reply, i managed to get the back off, and the battery is firmly connected.
Ill try reverting back to fully stock android with the guide you suggested. Hopefully that will sort it out, ill post again with results.

So my nexus refuses to boot or charge it seems. If i plug it into charge, the screen backlight comes on but doesnt display anything, and it doesnt seem to charge either.
What can i try to bring it back?

I haven't done anything to it since my initial post. All I have tried to to charge it. and its not doing that, all I get is the screen backlight switching on, and thats it. No access to TWRP now, the bootloader screen isn't coming on when i hold both volume buttons and the on switch. The device isn't charging at all. I dont understand what's happened to it, it started as just not booting android anymore, So I've left it, and now its commited suicide and cant charge, or boot or even show the google logo / charging logo.
Most likely the USB/IO port is faulty or the ribbon cable is out after taking the cover off. Try taking the cover back off and inspecting the ribbon cable. There are videos and posts on how to fix/replace the port.
It's most likely not doing anything anymore because the battery is completely dead.

That's what it sounds like to me too... Can't say how many times I've taken my computers & phones apart to fix one thing, only to find out I knocked a ribbon out of place in the process... Had to go back in.
Luckily the nexus 7 is easier to get into
Right, I've opened it up and checked the battery cable and the ribbon cable near the battery connector, both are fully secured in. So I don't think that is the issue, how difficult is it to replace the USB? I would take it in for warranty repair but I've got paranoid android on there so if the techies get it working, its gonna boot showing paranoid android on the boot logo. So I feel like I've screwed myself a bit here.
It will not boot, No google logo , it doesn't seem to charge, no battery logo, and I don't think anything happens when I connect it to a PC. All I get is the backlight come on and sometimes white flickers on the screen for a few seconds when I plug a charger in.
Has anyone got any suggestions on what I can do, I don't know what the stance is on having custom firmware on the tablet and needing it repaired.
Edit: I have an "Anything Happens" cover plan on my N7 from PC World UK, but I don't know if they cover a device which has had its bootloader unlocked and still has custom firmware installed.
What is the Google warranty like on unlocked bootloader devices? Do they not cover it or would they accept it?

So in the end, Asus did a free warranty repair, and the problem was with the USB port.
The paperwork I got back didn't detail anything, it just listed USB port and Firmware problem as the repair work. I'm guessing they reconnected the port, and then fully stock flashed it then sent it back.
Hopefully this post will help someone out there

well as I'm sure you all did.... the first thing I did when you got your N7 was to unlock and root it so you could load up all the games that you worked hard at on your phone... everything was great until it slipped off of my car seat when I got home and now it will not recognise the USB port while its powered on... my computer will not recognize the device at all to transfer data either... luckily I have already unlocked/ rooted and loaded team win recovery...
so here is my question... where can I look to see if something got broken when I dropped it... I took off the back cover and and everything looks ok...
my other question is will google replace it if I send it back saying that the cable does not charge while powered on... I can not relock/ return to stock without usb/adb connection
the length of turn around time that I hear about with the 16gb models I might wait it out to see if I can deal with it... I have a wifi web sharing app that I can use even though its very slow compared to a direct cable
If you can get back to the stock rom ...I'd sent it back if it's all possible.The Rma is quick and painless if your tablet was bought on Google Play.
- The turn around time for me on a 8gb and 16 gb tablets from Google play was just a few days. (Under a week from the time I called until the time I got my tablets in my hands. )
Well I let it charge off for the night and it is charged 100%... I guess I'll just rely on wifi connectivity for a while and see if I can manage before I try and return it

That really sucks man typically they won't replace a device that has been unlocked. Have you tried a factory reset yet? I I know it sounds unlikely but I have had accelerometers go to "sleep" from being dropped and or a faulty rom and a factory reset brought it back. Its really weird since you do get a charge when its off.. if it was broken hardware I would think you wouldn't get a charge at all. Make sure you do a nandroid backup before so you can get your apps back if it doesn't fix your problem.
Also about the RMA for the 16gb I believe now they are actually out of that model at the time. They may have a stash just for returns but if you decide to try a return I would make sure to find out what the estimated wait time would be.
Sent from my Nexus 7 using Tapatalk 2
Yea that's the weird part... But I did flash it back to stock ROM but nothing worked... If I could get USB to work I could flash it back to stock and lock it... Its a loose wire somewhere inside I'm thinking

My N7 16gb charged properly on the first charge. Now on the second charge, it will only charge while powered off. My device is stock and has not been dropped.
I plugged it in last night, while powered on, and woke up to find the battery in about the same state that it was in 8 hours earlier. That was with it plugged into a 2.5 amp HP Touchpad charger. I tried plugging it into a 1 amp charger and got no indication that it e was charging, until i turned it off. Then it put up the charging indicator. I will try using the N7 charger and see if that makes any difference.
It is possible, but very unlikely, that the device is doing a handshake with the charger when the device is powered on, and if it fails then refuses to charge. If that were happening i would expect to see a warning pop up on the device.
UPDATE: My device will charge properly off the asus charger that came with it. It totally sucks that the N7 appears to do a handshake with the charger. My advice to the OP is to make sure you only use the original charger.
Does ADB wireless work? Might not help you with fastboot, but you could push/pull files...
Yes all wireless connections work fine... But I guess I'm just going to have to live with this issue since it was my fault but at least I am already rooted with custom recovery so I might get lucky and have a kernel that might be able to fix it...

Based on the post about the charger "handshake," maybe it's the charger that's gone bad, and not the device?

I dropped it cracked screen and can't unlock the screen, UK Repairs
Hi, hope someone can help :-0
I dropped my Nexus (oh dear!) and the screen's cracked. It powers OK, just I can't unlock as the touchscreen is not responding.
Asus UK can repair it, but can't quote me a price (because they've had so few repairs in yet)
Questions:
1. Anyone dealt with Asus UK repairs? Or any ideas of the costs of replacing a broken screen?
2. Can I reset the device by just using the on/off and volume keys as the touchscreen is dead
Thanks
As long as you have adb connection you can reset it to stock... I've got no USB connection so I cant... wugfresh toolkit has all the proper files to flash the stock image...
I've been doing OK with no USB... I charge it at night and I last me all day easily

Hey everyone,
I've tried searching, but no luck, so here's my issue.
My nexus 7 was around 25% battery last night so I plugged it in for the night.
Woke up this morning and the backlight was on, but the screen was off.
When I unplugged my n7 the backlight turned off. Hitting the power button had no effect.
I then tried pushing and holding the power button for roughly a minute, nothing.
I have disconnected the battery and still no response from the unit.
I plugged it back in for roughly a minute as well, still nothing.
Unfortunately I don't have access to a charger right now.
Is it possible the battery is dead even though it was on the charger all night?
Sent from my SAMSUNG-SGH-I747 using Tapatalk 2
Weird.
Just plugged it in to my car charger and it booted up. Battery is completely dead, so I guess with the backlight staying on all night it didn't charge.
Now why would the backlight stay on if the screen is off...

Don't go flashing different roms and kernels now like most of the idiots here, it could just have been your charger being faulty or a bad connection to the tablet overnight. if the problem happens again then you can investigate further.
BTW, were you charging from your PC/Laptop with a USB cable or through a wall adapter? i've had issues in the past charging my Nexus 4 and 7 not charging overnight on my PC
I feel like a broken record but since I've fixed a ton of n7s with loose battery connections, I would recommend checking the internal battery lead to make sure its not loose. Asus didn't do a good job of making sure all n7 batteries were secure and this allowed the battery to shift and pull the power lead out. Some clear scotch tape on the connector and one on the battery (avoid the copper tape areas) will eliminate this problem if that's what you have.

I ran into this problem. Initially, my Nexus 7 didn't start. When I plug in the charger the screen would flicker from time to time but there's no indication of charging. So I decided to open it up to see that the battery cable has loosened. So I managed to fix it and use it happily thinking that it won't happen again.
Since last week, the same issue happened. I thought it was the same issue and opened it up to see that the battery cable is firmly in place. So I got a shock. I removed it and re-inserted it again to see if it fixed it. But nope, it won't turn on. And now it's been a week and I don't know what to do It's nothing wrong with the loose cable cuz now it's firmly in place.
Now when I plug it in to charge, the screen will just flicker (as in the back light will turn on and off in 5 sec intervals). What do you think I should do? I tried holding the power button for 30 secs as well.
I bought this new from eBay and still under warranty. But I live in Sri Lanka. So when I bought it, I had to ship to a friend in the US and had to wait till he came down. So it's not easy for me to ship back and to receive another device. Hopefully I can find a solution to fix this myself.

Make sure that the cables between the battery and the connector are intact and not broken. One or two people reported a broken cable.
Does it boot while plugged in to the charger with the battery disconnected ? You could simply have a bad battery.

I checked again. The cables aren't broken. They are all in good shape.
It doesn't boot when I plug in. Actually it doesn't show anything on the screen. If I look closely I can see static flicker on the screen from time to time. Just like the static in TV but much much less. Like only a few of those in certain places.
When this happened the first time I opened it up to see the loose cable. So fixing that helped it then. But now I dunno what's causing it.

Might have to try a different charger, maybe something stronger. I JUST had that problem with my GF Nexus 7. It wouldn't boot with her normal charger and the screen would flicker like a TV. I used my Nexus 4 charger and it worked.
She had left the battery fully drain for over two weeks and I think the battery didn't appreciate it.

recently I noticed that my n7 is loosing battery even when charging, I was running cm10 with the kernel that came with it, and I tried switching to rootbox, but that didn't help... I'm using OEM charger with OEM USB cable, I just called Asus and they created an RMA for me, but I just wanted to find out before I send it in, if there's anything I can do to solve my problem on my own.....
Thanks,
Aryeh

The first thing to check I think is if the cable and/or charger is defective by using another cable. If not, you can restore the original 4.2.2 Android and ROM with Nexus Root Toolkit. If nothing changes, inspect the micro USB port for damage as they are extremely fragile. Asus’ warranty claims that your warranty is void if non-authorized personnel tamper with the device. So you should be careful if you decide to open the back to inspect if the battery is properly connected to the motherboard as I have heard stories of them not being connected properly. The last thing is to inspect if the battery itself is defective.
I hate restoring back to stock... Backing up my internal SD took almost a whole day... But but I guess I'll have to do that anyway if I send it back to asus
Sent from my Nexus 7 using Tapatalk 2
I would +1 with the cable idea. My USB cables get man handled like crazy so I am never surprised if they misbehave.
Also, I don't think it'd be too far-fetched to try a different type of 'power brick' if you have another (preferably Samsung) charger around. But I know these are less likely to cause issues for most users. However, if you're that adamant about sending your tablet back I would try this last.
In addition, does the tablet charge normally when powered off when plugged in?
When the screen was off i got from 13% to 100% in 4 hrs
I ordered another OEM charger from amazon and if it doesn't solve the problem I'll return it

So when I plugged in my phone last night and left it. An hour or two later I came back to it and it was hot (not unusual). Upon looking at the stock charger and micro USB port it was charred and melted. Phone will not charge, nor connect to a computer. I am running a week old version of liquid smooth march 14th (probably not important, but it will clearly indicate that I do not have a warranty to anyone at at&t). And I'm running the latest CWM touch recovery. I know people who also own galaxy s4s, so I can get a charged battery, but that can't be permanent. Anyone think there is a chance of flashing back to stock and possibly getting my warranty? Or should I just look into a new phone? Any recommendations? I haven't really kept up with this years phones.

You could flash stock and get warranty, but there's a good chance they'd send you back an updated phone. Your best bet is probably to get an external battery charger and have two on you, or try and get some other phone repair service. Otherwise, you send it in for warranty and get stuck in the same TW only boat with the lot of us.

You could get a new usb ribbon. Until then to charge, if you strip an old usb and connect it to the terminal on the back used for wireless charging it will charge your phone, kind of slow though

i hear mixed results on nfc. the samsung replacement battery cover is much thicker as it also includes an additional nfc antenna. theres a few aftermarket charging receivers that fit under the stock cover but i think the bigger ones cover the nfc antenna.
I've been having a few issues with my Nexus 4 on 5.1.1.
Twice in the past month I've had random Force closures of all aps. Facebook was the worst. But then it goes on to all other apps including the launcher.
First time that happened I did a factory reset and things went well. Yesterday it happened again while it was on another charger and I can get my phone to boot.
The screen backlight looks like is on when it's plugged into the charger and will go out if I hold the power button down for 5 to 10 seconds.
If I hold the power button down for 10 seconds when the charger is connected the LED flashes red till I take my finger of the Power button.
I've let it charge overnight (12 hours) and I've tried holding both volume buttons with the power button.
As well as Volume up and Volume down separately with the power button.
Is the phone dead? anyone got any ideas on how to bring it back to life
I've got a screwdriver set on order as I don't have fine enough star screwdriver to remove the internal battery connection. Which is my next step..
I think you are right to try replacing your old battery. Be careful while scraping it out where it is glued in not to tear it up too bad because it can 'splode. Might want to use a plastic card for that. I used a metal shim, an iOpener, and am much better now...

I'm going to try just unplugging the battery from the board first before I attempt to replace it.
Think it's time for an upgrade anyway.
Got my eye on the "OnePlus-X" as my next phone.
Removed the battery and stuck my multimeter into it.
It's got V output of 3.61 volts but amps drop off a cliff to zero as soon as I touch the contacts.
New battery arriving tomorrow.
i have the same problem with my nexus 4 dude. it boots when it is connected to the charger. basically it works like a desktop. I went into recovery mode and did a fectory data reset and wiped all the cache. Pliz help me proceeed. I kind have a hunch that its a software thing. did yours start working ater change of battery?

And it's getting sent back today!!
Got it through Amazon and when the battery arrived it looked ok but would not charge. I took it out to check the contacts and the ribbon came away form the battery! Looks like it was not soldered to the battery properly (if it ever was!) Just glad it didn't cause a short and kill the phone or myself.
Getting one from a different supplier tomorrow. Hopefully this one will work!

Please let me know! I've ordered a third battery just now. The first one was an aftermarket one, the second one was apparently a knock-off, this one was smaller than the original one.
The third one is hopefully a genuine LG one since the reseller is listed on LG their site.
Dam!!
Replacement battery arrived today. Looks good.
Installed it and the same thing is happening!
Screen backlight goes on. does not seem to be charging!
Now thinking the motherboard is buggered!
But I'll keep the phone on charge overnight just in case...
Damn that sucks to hear man. Hope it works tomorrow!
Now just searching freebe sites and eBay for any damaged cracked nexus4's I could scavenge from
