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.

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

So.. my heart us a little broken tight now and not quite sure what should be done.
Here's the run down I have the first waves of transformers, rooted was running aokp build 31 before the screen fail.
Its been fully charged it at least I think it has been (can't really tell). At first I thought it was simply the screen not coming out of sleep.
So I had held the power button down for the 11 seconds or whatever it was, and heard the speakers do the power down poppy noise.. but now it will not turn on or boot.
Any ideas on what to do or where I should/could go or send it would be greatly appreciated.
Thanks

Does adb work? Can you get ANY response? Full charged and plugged in?
Hi, sorry for putting out this old thread, but I dont want to open a new one.
Have the same problem. I cannot get in ADB and the TF does simply nothing. Have gouveur kernel..
Try charging it again.. Maybe its just empty after Kernel Panic...
Sometimes I have to hold power for like 10 seconds wait 2 seconds then another 10 seconds for some reason. Hope it helps.

Same here. Mine wouldn't turn on this morning. I did the whole button finger dance and nothing. Let it charge, even though it was already charged and then did the same button thing for 5 minutes and it just came back on.
Can anyone one of you get into APX mode (Vol Up + PWR) and have your OS see your device? IF you can, then you use NVFlash to reflash your stock firmware (or custom ROM) and restore your backup, if you made one.
I just soft bricked my TF101 B50 and saved it with this --->
http://androidroot.mobi/2012/05/27/introducing-wheelie-nvflash-for-asus-transformer-tf101-b70/a
FYI, I am on Linux but you should be able to open the .sh file and use the same commands. Either that or there are Windows programs that use NVFlash binaries. Easy Flasher is one that I can think of off the top of my head.
No, cannot boot APX..
Just tried the 10sec.press+2sec.wait for roundabout 5 Minutes as above written and for 0,5sec flashed the emtpy Battery symbol on the screen. Keypad says full Battery. I think it is not charging when its turned off..
Will be on Holidays till thursday and try then APX mode trough the Keydock.. Hope that works..

I am in the same boat. TF101 that is out of warranty and just all of a sudden stopped turning on. I have a dock as well and the dock full charges, but within the dock or out of the dock and connected to ac power, it still wont turn on or show any response at all. No response at all. I have tried every button combination i can think of and find on the interweb. I really hate that the tablet doesnt have a light indicator for power. While the ac adapter might be fine and charging the dock, the internal part of the tablet where the adapter connects could be damaged or something and never getting power (docked or not) and we would have no clue. Havent looked into seeing if I can install a new battery and how much a new one would cost, but that still wouldnt solve the issue with getting power in the first place to charge or function. Any suggestions or ideas outside of what we have already talked about in this thread?

RMA to Asus. Mine had some serious issues staying stable and I obtained a RMA for a refurbished unit I bought from Newegg in February. It was in Texas one week and is being returned tomorrow. I don't know what if anything was wrong with it or if it even works when I get it back. I do know it was a door stop when it left and it only cost me shipping there to give them a shot at a repair. It was my last hope for a great tablet.
Good Luck

Just got mine back from ASUS after a short visit to Texas. They did not charge me to fix it, but they did not say what was wrong with it either. I am just glad to have my tablet back. It appears to function normally now. Great service from ASUS with my money.

So now I came back from holidays and boot the TF without any problems. "It just works"
Will write again if any problems will appear.

I had a similar problem with mine... Let it sit for a few days and it magically started working again.
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,

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

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.

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

Ordered a second P2XL since they were $200 off. It was suppose to arrive Thursday but got delayed till today. Opened it up and attempted to turn it on, NOTHING. Put it on charge using my other OE charger, 10m later, NOTHING, 1hr later still NOTHING. I cant get it into bootloader. No LED or charging screen, basically no signs of life at ll. It does nothing when plugged into the PC either.
Anyone have any other ideas to revive this unit before I have to advance RMA another one? It won't ship out until Monday anyway, so I'd like to try my best.
I had a similar problem with a Nexus 7. I put my charger on a power strip that had an on/off rocker and toggled it a bunch of times until I jumped the battery back to life. It might be worth a try. I got the same deal this week and mine arrived at half charge. No issues for me. Sorry for your bad luck.

I did attach it to mu other P2XL and it does recognize that it's plugged into another device and I can choose supply power to device. I don't think it is though because battery is not dropping on the donor device. Sucks because I NEED the device now.
If your battery is totally flat it can be really hard to jump start it, which is why my Nexus wouldn't even take a charge after being totally run flat and shelved. Sending pulses of voltage in repeated bursts charged the battery enough to restore it's ability to charge. This may not be the case for you but it helped me. I found this method on xda.
