Hey guys,
I've been noticing something unusual with my tablet. The stock hard-reset recovery(as well as CWM) only works with USB plugged in. When it is not plugged on the computer, it hangs on the black screen with the Google logo(when it is oem locked, there's a lock on the bottom). I am also a Galaxy S2 user so I know that I didn't need the USB plugged in, in order to enter the recovery mode.
Is this normal for the N7 tablet? or is there something wrong with it?
Thank you

I have the same issue, and I always thought it was just me. Going to try a different recovery when I'm back home.

Yeah it's weird. Even after coming back to stock, unrooted, the hard-reset via stock recovery doesn't work unless USB is plugged in. Maybe some files are missing
Wow, I'm glad I stumbled on this thread, I was going nuts trying to figure out why I couldn't boot back into CWM after going back to the stock image and applying the OTA .zips.
Confirmed, I can get it to boot into CWM from fastboot only if I have the USB cable plugged in. Otherwise it just hangs on the Google splash screen.
Weird.
I've been able to boot into recovery using the app "quickboot" which had an option to reboot into recovery. My usb cable isn't plugged in.

This sounds a bit like my Nexus S i9020. It will only go into bootloader without the usb, and only go into download mode with USB attached (although it doesn't have to be powering it). This is the same on both handsets I've used. Maybe not a 'flaw' and more a nod to using fast boot/adb?

I am currently having the same problem. Did anybody come up with a fix for this?
I'm having the same issue with the nexus 7. I've found out that you can boot into recovery if you have ROM Manager installed and select reboot into recovery.
Does anyone know if this is an OS issue or recovery issue?
Interesting. Was wondering why I couldn't get into Recovery from the Bootloader.
Another bug for me is that if I boot into Bootloader with the USB connected, I cannot make any selection using the volume keys. Only works if I boot in first without USB connected, then connect once I'm booted.
Its a bug, guys learn to search in the Development threads, I'm sure its being worked on,personally I've been able to get into recovery without have to connect via USB, if all else fails you can enter recovery via USB and ADB, by issuing the command adb reboot recovery in terminal/cmd
I had the same issue last week. Not sure what changed but now I'm able to get into recovery using the reboot menu or good mngr/rom mgr. No need for usb. I'm on modaco rom and used both clockwork and twrp.

I have one more problem...
When I connect USB, the keys don't work in bootloader so can't try recovery with USB cable on.
Any solution for this?

There are two different versions of CWM- one uses the power and vol-up/down buttons for keys- the other used the tablets touchscreen for button press functions.
You may have installed the touch(screen) version of CWM- try using the touchscreen for controls.
Same issue here. I can get to recover either connected or via rom manager.

I too can get into recovery via ROM Manager. I read somewhere that pulling the battery might help. I know that's a bit of a pain on the Nexus 7, but I'm going to try that when I get home later to see if that helps.

Nope, disconnecting the battery didn't change anything. Wug Fresh (Nexus Root Toolkit developer) informed me on Google + that it's a Google issue and it should be fixed in a future update. For now i'll be either plugging in USB to computer or ROM Manager.

Try Quick Boot
Free, easy to use, will boot to bootloader, recovery, reboot etc... requires root of course, you already have that.
i dont't have root because it was screwed up right fromt he get go
Alright, I am having some trouble with the Nexus and hopefully someone can help me with this. Then Nexus was unlocked and rooted but I was still rocking the stock rom on there. The tablet used to be recognized by the computer and everything was fine. I used a car charger today to charge the tablet, came home, and the tablet would no longer show MTP when connected to the computer but rather would only charge.
I thought it was an issue with the rom so I downloaded a new rom, made a backup and went to flash it. Something happened when I was flashing the rom which forced the tablet to reboot and all it would get to is the Google screen. It won't go past that. I can get into the bootloader but can't boot into recovery or the system. Its not being recognized in fastboot mode either so I have no way to flash a recovery onto it...
Any suggestions?
have you tried force rebooting it a few times to try to get it ti boot up?

The device is not recognized by the computer at all and the bootloader freezes then I connect it to the computer or the charger.

Are you two able to get an adb connection? If so, and you can get into fastboot, you can download and flash the Google factory ROM.
If you are not familiar with adb, try the Nexus 7 Toolkit from Skipsoft.net to flash the OEM ROM.
I'm not the lowest of the low, but I am the slowest of the slow.
I had similar issue
When I first unlocked and rooted my N7 .... and then tried to flash AOKP, I had a very similar issue as it would not boot into OS or CWM! SO i left it for some time and then crossed my fingers and tried to boot into bootloader 1 day later and then CWM ..... and it worked!
I think this is quite good advice for u to try out!

I can get into fastboot but once I connect the usb, it freeze and the toolkit I used (GNEX TOOLKIT) couldn't get my device :crying:
And sorry to ask, what is adb connection?
I only know fastboot, now my N7 only can boot in fastboot without usb plug in :silly:
But I will try to use the toolkit you recommend me, hope it works :fingers-crossed:
Thanks a lot

Google Fasfboot and ADB. Between the two of them, you can flash recovery, push & flash ROMs, etc. The Nexus 7 Toolkit makes Fasfboot & ADB commands pushbutton choices.

I have a broken screen and digitiser - I can see nothing at all on the screen and it does not recognise any touch movements.
The phone does appear to turn on and is recognised by my computer.
I want to retrieve all my data - photos, videos etc - from the internal SD card.
Unfortunately I did not have USB debugging enabled when the screen broke.
Is there a solution to achieve thiis?

Connect with usb and copy your files to the pc You don`t need usb for that.
Thanks for your reply Gee but that was, oddly enough, the first thing I tried.
The computer recognises the device as a portable media player and there are no files found in the device.

Maybe my original post wasn't too clear.
I need to retrieve all my data from the S4, and the conventional method of plugging in to my computer via USB does not recognise any data. Would I possibly have to select to mount the card to view? Either way, this is not an option due to the broken screen.
My next thought was to use ADB to transfer over all the content of the internal SD card, however, my S4 is not recognised using ADB (I assume as USB debugging was not enabled when my phone broke?)
So, is it possible to enable USB debugging without use of the screen on this device?

Can I flash customer recovery, though, as I can't see my screen?
You could install ClockworkMod Recovery and use ADB to retrieve your data while it's in recovery. You can put your phone in download mode by pressing and holding Volume Down, Home and Power buttons till it vibrates. Then press Volume Up to confirm that you want to enter download mode. You should then be able to use Odin to install ClockworkMod Recovery.

you can boot in download mode and flash it without screen. see if odin recognize it
In my opinion if u could turn on usb debugging that would not bring back your lost data. Not really sure though. You could do that by connecting a micro usb to hdmi cable to your tv and then i guess you could use the phone there, not sure if the touchscreen would work though but worth a try..

be sure that you boot in custom recovery, connect your phone, open cmd in adb folder (shift + right click) and type (no need to enable usb debug):
Code:
adb devices
you must see the serial number (in recovery mode)
Code:
adb pull /sdcard/
use attached adb folder

Because I can't see the phone I'm not sure the state it's in.
Is it just Volume-up + Home + Power to access customer recovery?
I can now see the device in ADB.
When I run the adb pull /sdcard/ command I get an
error: device unauthorised. Please check the confirmation dialog on your device.

hmmm do you read "recovery" in command line after the serial number?
there is a dialog box showed on your broken screen, try to tap on, maybe you will hit confirmation

Okay so i have a nexus 7 right? yes, but im fairly custom to rooting and all that stuff. Well im not a nub at this stuff but i need help once in a while XD, i just got the thing to turn on again i let it die completely and the charging bug decided that it wouldn't charge. I ended up jump starting the battery and now it turns on but now i plug it in it turns on right? yes it does but now i can get access to any data thats on it. (P.S there isnt any data on it since i had to wipe cyanogenmod 6.0.1 off it) and theres only twrp recovery on the tablet, i can access twrp and the boot loader (unlocked obviously) but i cant access fast boot or push files via adb. The charging port is still good on it i know that we had it tested on a friends tablet and it worked fine. OTG usb doesn't work either i cant seem to get data on the tablet but it turns on when i plug it in, it doesnt charge when plugged into a wall adapter or a pc it just turns on when plugged into a pc. Any and all info is appreciated. (sorry for my spelling errors if there is any, also i am on linux so i dont need drivers as far as i know, i also tried on windows and its a no go the device doesnt show up on either os)
nexus 7 2012 btw

Eh just dont bother guys im pretty sure its dead, the nexus help forums didnt have anything.

Thanks for the help but sadly ive tried that...
As the device can go into fastboot and twrp with adb and otg without data transfer being possible I'd say most likely the port is broken.
Just to be sure no adb or fastboot commands work at all right? even those which don't transfer files. If they work then your partition layout is messed up which could be fixed

Did you try to charge the N7 via wall adpater or the pc? Did you use the genuine charger that comes with the device? What does it look like when you plug it into your pc? Did it show up as a mtp device (or any kind of device) ?
Try charging the N7 with genuine charger, or via pc. Make sure you install the driver for the N7 (go google it) before plugging in. Judging by your status, it appears that you're having a defective charging port or mainboard. Usually you'll end up sending it to the manufacturer to get them replaced (hope that it won't happen :3 ).
Have you used the push files and adb function on TWRP? To the best of my knowledge, these errors don't come about often in TWRP. If you don't know to use it, look it up on Google or the Xda threads. One more thing, losing fastboot is pretty rare with N7, so if you're not sure whether the fastboot is VANISHED, go to this link: http://forums.androidcentral.com/go...1477-guide-nexus-7-factory-image-restore.html

You should try to go to fastboot and connect it since it loads low level drivers. Have you read the linked post and tried the steps?

I'm not really sure, whether my port is broken or not. Shortly after I posted here, I found out, that I missed the Standard USB-Protocol-Setting in developer options (it was checked as charge). So I changed it and voila, USB worked!
But then I tried to install twrp (which was successful at first, but seems to be overwritten again by stock recovery) and now I can't get my device to connect again. I tried to disconnect, connect with other PCs, change the usb-debugging and standard usb-protocoll, connect in fastboot-mode, nothing works.

It's me again, I solved my problem!
When I tried to connect yesterday I noticed that my phone always charged and then immediately stopped charging again. It was charged to ~80% and didn't go any further. So I thought maybe the battery calibration is faulty, which can happen when you never fully charge. So I emptied the battery, charged it while phone off and tadaaa everything works.
It seems my phone interrupted the usb connection because it tried to charge my phone over 80% and the controller stopped it.
