ADB device offline - after upgrading TWRP and 4.2 ?

So I have had my Galaxy Nexus since the day it came out, I rooted it before I even activated it.
Like many, I have used all sorts of different ROMs over the year period.
I have never had any problems with adb or anything. I have pushed and pulled files and all of that numerous times.
Until yesterday, I finally upgraded my recovery from an really old (first touch based recovery) to the newest TWRP. It worked fine. I put my phone into fastboot mode, and was able to flash the new recovery through the command prompt (adb/fastboot) on my PC. Then I switched to a new 4.2 rom (Paranoid android 2.99)
So today, I wanted to try some editing on some system files, so I went to go pull some files off of the phone (using adb of course), but now it just tells me that my device is offline.
I tried
"adb kill-server"
"adb start-server"
"adb devices"
It lists my device number, but just says "offline"
I tried to update everything. (Samsung main Drivers - Google's USB SDK drivers - and the newest version of android-sdk)
Also made sure that my USB-debugging was set on my phone.
Even if I put my phone in fastboot mode, it doesn't recognize it anymore. Which is weird because just last night it worked perfectly fine when I upgraded my recovery. I am frustrated to no end...... Can anyone else tell me what I might be missing here?

Nobody?

only thing i can think of right now, before suggesting omap flash or odin, would be try a different usb port, another computer, another OS!

try installing the latest CWM recovery and see if it helps.

Try going to settings and look for something related to Root Access and it would have three options:
1. Apps only
2. ADB only
3. Apps & ADB
Choose the 3rd.
You might have to hunt the exact location under Settings where this option will be available as I don't remember them exactly.
Hit Thanks, if this helps...

I looked, but I don't see those settings anywhere.
I tried multiple USB port's. Switching from my USB 3.0 ports to my 2.0 ports. nothing. I can still access the phone storage. So I know it is still connecting to the PC. I could try to boot up linux, but I don't have any of the driver's and sdk tools on my linux drive, and from what I heard it was hard to get it all running in linux.
I guess I could try to change recoveries from TWRP to the newest CWMR,
but last time I turned my phone off, put it in fastboot mode, adb didn't recognize it. So im assuming it won't let me flash anything. Unless fastboot sees it but adb doesn't?
I mean my phone is working perfectly fine, running the new recovery and rom. But I have to be able to connect to adb. Not only for modding but in case of an emergency where I would need to flash.

I understand your situation... Since you were not able to locate the option suggested, a little Googling answered it's location, check for same and confirm:
Settings > developer options > root access > apps and adb
This should hopefully help resolve the issue.
Hit Thanks, if it helps.

hi. i try all this ways. i know that my usb debuging have problem, in development option i'll checked this, and it says enable. but infact it's not enable and still i got device offline error.
also i use z4root app and when i touch on root, it says that rooting need usb debuging enable (please enable it)!!
then move me to development setting to enable that, but this was checked and enable.
is any way that we make device online from my phone? for example using terminal emulator to turn on usb debuging or turn it off. this way is only my way! any one know some trying this?
i also use usb debugger app, but it move me in settings too! LOL
i need enable my device to root that.
thanks every one

I know this is an old topic, but if somebody else googles it, I had that offline issue, the solution was to upgrade adb : http://stackoverflow.com/questions/10680417/error-device-offline

You simply need to upgrade to the latest version of adb. Went thru this a few weeks ago.

[Q] Kindle 2nd gen issue

Hello all.
This is my first post and my first experience with android devices so please go gentle.
I recently purchased for £20 a kindle fire 2nd gen otter.
The reason it was so cheap was that it is stuck in a bootloop.
The friend I bought it from intended to bring it back to life and install CM to the device but never got round to it. So I took it on as my little project.
I have been scrolling through pages and pages of google and this site for research but have hit a brick wall.
I purchased a factory or fastboot cable knowing I may well need it. I also have the original cable.
When trying to boot the device I get the usual kindle and fire logo orange as of it's booting then every 10 seconds or so the screen will go black and back to the kindle fire bootloop.
I have tried to use the normal cable to link to my desktop on windows 7. When doing this the device will not show up in device manager at all.
When I plug it via a fastboot cable it boots into fastboot with a green flashing light on screen and is recognised as an otter prod 04 on device manager.
I have installed the latest sdk. Also fastboot.
I have changed the windows environment variables under path on the PC and can successfully run fastboot in a command window. I can also issue adb commands through also a dos command window so I know both are working correctly on my PC.
I have typed in fastboot devices
I have also typed in adb devices.
When I issue either or these commands my device will not be found through the command window. It just returns a blank.
I know this is due to drivers not working correctly so have opened device manager. Update driver , have tried the android sdk path for drivers have also tried my adb drivers. I have also downloaded the latest Google USB driver and none will install. I have a programme running that allows any unsigned driver to be installed on win 7 so I know it's not that.
All I have returned is cannot install drivers for otter prod. 04
The only thing it will accept is choosing from a list of devices, Then android. And installs as adb device or adb composite device, this is obviously useless as I can't boot device into normal mode to be able to use it as adb or issue commands to it.
I have tried everything. I know this kindle is save able I just don't know how. My end result is make it bootable, root device and install CM
I have trawled through loads of pages of info and tried tried and tried for answers but nothing works. Can anybody shed some light on the issue for me.
Many thanks in advance

Just thought id add, I have also tried all timed variations of holding down the power button
I have also let device run flat and recharge. Have also tried a different PC and USB port.

Hello Vincent,
ADB stands for Android Device Bridge (Just wanted to point that out since you are new to Android).
The ADB Composite Device driver lets your computer and your Kindle Fire device communicate with each other. This includes ADB as well as fastboot.
Install the ADB Composite Device driver in Device Manager and then go to the command line window and type fastboot -i 0x1949 devices and it should now show up in fastboot.
Now flash the stock bootloader, recovery, and system img files to your device. After that, you should see it boot successfully.
Hope this helped, and don't be afraid to ask me more questions about your device!

Why can't I get Windows to recognize a G4 in Fastboot mode?

I'm trying to unlock the bootloader on my daughter's G4, and I have run into a heavy snag. I get "code 10" (driver can not start) when it's in fastboot mode, but I'm fully able to connect with adb when the phone's up and running. This is not my first rodeo, and I'm sure the USB cable works (original cable), I have enabled USB Debugging (or ADB wouldn't work in the first place) and I think I have done everything else that should be done. But the damn thing won't work on any of my computers, under Windows 7 or 10. Driving me nuts! Also when it's booted up I see it as an LG Mobile ADB interface, but when it's on Fastboot it insists that it is an MTP device, even if I have set it as a PTP device when it's booted up. Can anybody please tell me what I have to do to get this to work? Another thing is that if I run "adb reboot-bootloader" (or even the wrong syntax (at least I think the dash should be there) "adb reboot bootloader", which LG's page says), it will not boot into fastboot/bootloader, it reboots into Android. So I have to get into the setup by holding in vol + and plugging in the USB cable. But I don't know if this is related.
Edit: Oh, btw, I have tried to find the latest drivers, so far I'm on 4.0.0.0. They are dated May 2015.

FireTV1 (rooted/bootloader unlocked/cwm installed) Bricked. No light, no logos.

So I bricked my FireTV last night during an upgrade to rbox's latest fw...
Short story is, it got to the Amazon app optimization after the flash fine so I went back to the computer to start working on the second box while it did it's thing. I mistakenly sent the reboot recovery command to the box that was optimizing itself. I didn't notice I was sending the command to the wrong box until I saw that my second unit was not rebooting to recovery.
Needless to say, it now no longer boots to any logos, and does not turn on at all (no light when plugged in, not even for a split second).
What are my options to unbrick? I'm taking a guess that the SD reader/eMMC method is the only one. If so, is it possible to retain an unlocked bootloader/etc with this method? I've read you'd lose it, but I'm not familiar.
If someone could point me in the right direction that'd be awesome. I tried google but it's filled with loads of outdated or unrelated information (mostly debricking if the amazon logo appears) or info from when the initial hardware root method came out.

i am in the same boat. if you find anything let me know.
after following the downgrade tutorial, I executed the command as instructed adb reboot recovery
device reboots into recovery,
update starts..... after while reboots...
upon reboot
no light on device no logo on screen - black screen
connecting to win7 machine with USB cable it initially recognizes the box, but cannot connect with either ADB nor FASTBOOT - searching for device

At least you can connect with USB! I get no connection at all to the pc with a A-A cable.
I would suggest for you trying to get the timing right and initiate the fastboot commands right when the device is recognized.

You people need to reflash your partitions, this happened to me months ago. Can't search for the thread now, I think the steps were in the FireTV1 5.0.5.1 thread...

my device bootloader is not unlocked. I was following the steps to downgrade firmware in an attempt to unlock the bootloader.
in Win7 Control Panel > System > Device Manager the FireTV1 appears as QHSUSB_DLOAD - i think I am also going to try this ... http://forum.xda-developers.com/showpost.php?p=66961740&postcount=676
thanks for the advice ldeveraux, ill take a look.

Ordered the eMMC adapter from exploiteers. This is likely the only way I'll be able to fix this as the USB A-A cable is not detecting my FTV

Well I managed to get my device talking with an A-A USB cable while waiting for my eMMC adapter. So now to flash
Is there a way to recover with this method without losing the ability to unlock the bootloader? Bootloader was unlocked prior to the brick.
UPDATE: annnddd it didn't work for me. Was getting I/O errors while writing and now the device no longer gives me partitions in /dev/. The usb device still shows up however.

how did you get the /dev/ partition to appear ?
which linux distro did you download / install as I cannot see any partitions on my device
did you use the linux in a VM ? & did you have the windows drivers installed beforehand ?
thanks

Obtained Sprint Nexus S 4G, Stuck on ICS

So my buddy gave me this Nexus S 4G, since I like to collect phones. Unfortunately, it appears to be stuck on 4.0 ICS. I tried to check for an update to 4.1 ICS, but for some reason, it reports that my phone is up to date??? Wtf. So I tried doing it manually, I can't flash this random OTA which may or may not (probably is) Jelly Bean in stock recovery, but it fails. I tried doing it even more manually using fastboot, but for some reason, I can't get the USB drivers to work. My next step is to use a Macintosh, as they seem to work better with Android, but I don't have access to it yet. In the mean time, is there any other way to get this phone updated or, at the very least, rooted and ROM'd?

@Dr. Hax
I'm assuming you are using windows? If so burn a Linux iso, Mint or Ubuntu are both great. You can make a bootable iso using a thumb drive or CD. Then set up your pc for dual boot. You'll never have a driver issue on Linux.
I'm sure you probably know this but how I have gotten windows to work and see my device is install the fastboot and adb 15 second installer from here: https://forum.xda-developers.com/showthread.php?t=2588979
Then reboot of course. And when I plug my device in have developer options enabled and usb debugging enabled and be watching phone for the little box pop up that you just checkmark really quick so your pc can communicate with the device... Also if you scroll down on the phone in developer options to "default usb configuration" and change that to "file transfer", that will usually bring the little box up on my devices to check mark so they can communicate..It only shows for a second then it's gone. But if it hasn't popped up yet then open terminal and type sudo adb devices (hit enter) and again be watching your phone because that little box should then come up that you must quickly check mark on phone so pc and phone can communicate.
I always uninstall and reinstall drivers on windows and reboot afterwards. Also make sure check device manager and see what's there. But that 15 second fastboot adb installer for windows is a life saver and makes it all super easy!! On Linux none of this happens. Ever! ? You just plug in your phone and the model of your device shows up on the computer screen. IDK if this makes sense much but I tried to word it where it did best I could. Hopefully this helps or you already got it going.
