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.

Android 5.1.1 OTA Files Online

Whoever wants to update the Zenwatch via ADB Sideload, here is a Link to the OTA File.
The others will receive the update pretty soon as it seems that the OTA has been triggered.

Worked fine for me. But don't expect WiFi

For me, it was a nightmare. My Android SDK was out of date. Even when I upgraded, I was left with a lower revision of ADB than I needed to push the update. I had to completely uninstall and reinstall the SDK. Even then, the ADB wasn't the right rev. I found some obscure posting on XDA thst said not to use ADB, but ./adb (Ubuntu based system ). This worked.
Once I got it updated, the watch had nothing but issues. Lots of lag, connection issues, and inability to use any of the Asus watch faces. I had to do a factory reset on the watch. It took about 45 to sync all the apps (not sure why it took so long, I really don't have many apps.)
Things seem to be settled in now. We'll have to see how it goes.

I also had issues. I struggled with ADB problems as well. I finally updated my Android SDK. I still had issues, but it finally worked. All was well, but I noticed an app that was on my watch but not on phone. (my fault) Reset the watch and it took forever to sync. Finally, all is well. So far, I like it.

ADB Sideload was a pain in the a** for me as well. Also had an outdated version but went for "15sec ADB" on XDA. Worked fine.
However ADB always found two devices. On my Mac I had no idea how to fix it, so I went to Windows, disabled the offline flagged device (which was not the one I disabled first of course. And every disable requires a reboot. Windows really didn't improve at all) and ran the ADB Sideload afterwards.
At the first boot of the watch everything was running like crap. Rebooting helped and made everything smooth for me

Got my update early this evening.

What's worse when you try to sideload the Zenwatch is that when you sideload it via Ubuntu, it needs a udev rules entry. But I can't find that anywhere.

no need to push, I found a trick.
If you want the update just uninstall the zenwatch manager. Then on your watch, hit reset to do the factory reset. After its done reconnect to phone and it will first install the old software and then you can select "system update".

I'm really confused, I dont have bluestacks installed, its showing one device when i connect my watch, then when i reboot into recovery it shows the same device 2 times, one is sideload, the other duplicate is offline...its not allowing me to sideload the zip because there is more than one device or emulator attached, also tried adb kill-server then adb devices, still the exact same serial.... what am I doing wrong?

I don't think you're doing anything wrong. I ran into that too. I updated my Android SDK, and tried again. I had to restart the watch a few times after updating the SDK and it finally worked.

Any idea when will the official OTA from Asus be rolled out?

Heres how

I think a lot of us found our old ADB version out of date since it still worked on most phones. Android Wear obviously wants the latest and greatest, and it was the watch that complained about the ADB version. Here's where to grab a quick basic install of ADB and Fastboot from an XDA contributor - I installed it and once I restarted the phone and used the newer ADB to put it in recovery and sideloaded the file all was well -

If you run the whole sideload process on Windows (I had to in the end because I didn't know how to get rid of one of the devices on Mac OS X) just disable one of the devices, check which one is still available in ADB. If it's the sideload version, great. In this case you can sideload the firmware. If it's the "offline" version, disable it and enable the other one again.

As I posted above, I got mine days ago.

how do you disable a device? I think my problem is that both devices shown have the exact same serial numbers, once plugged in it shows one device, once it goes into recovery, there are 2, one offline, one sideload. I used the links above on a different computer and it does the same thing, after multiple reboots and adb kill server commands. sorry for being such a noob, I really don't want to annoy you guys. but thank you for all the help, I may just wait for the OTA update hehe.

Adb recognizes devices during phone on state, but not in fastboot.

Okay so now that I've scanned pretty much all of what the internet has to offer on this issue, I'm helpless and forced to write a new thread here about this.
Yes, a similar question has been replied to a million times before, but absolutely none of that helped, made no difference whatsoever.
So earlier, I was on the stock rom, with TWRP flashed and root access. But wanted to switch to the community build. Tried the twrp trick to install the CB but that didn't work, so flashed the stock OP3 rom and flashed community build.
All went fine, until I tried flashing back TWRP. Used the traditional ADB method of doing that, seemed to have flashed it but tried going into recovery only to be presented with a black screen. I got fed up of that trying to fix it for a whole day so I just left it, because I could still boot into the OS and that worked fine.
Fast forward to about a week later; somehow the flash didn't work and I still have stock recovery. Now I try flashing TWRP again, but I discover that my device doesn't get detected in fastboot. It absolutely refuses to.
It DOES, however, gets detected in the OS just fine.
I've tried every which way, absolutely NOTHING seems to work AT ALL.
- OEM unlocking is checked, if that makes a difference
- USB debugging is turned on
- Uninstalled all USB drivers related to the device, and installed them via device manager (but it gave me this error:
"the folder you specified doesn't contain a compatible software driver for your device. If the folder contains a driver, make sure it is designed to work with windows for x64-based systems)
seeing as I'm on an x64 version of Windows (its worked before with my Nexus 5, I swear)
- Tried it with different adb fastboot files, from all over the internet. All of them show just that blank space after I type in 'adb devices'
- Installed universal adb drivers.
- Samsung drivers.
- Obviously the official OnePlus drivers.
- Used Usbdeview to uninstall / force stop and re-installed the drivers.
- All in one tool
Now I'm thinking, I should try to re-lock the bootloader and unlock it again, or do like hard rest sort of things. I have no idea though, how this would affect the detection in fastboot.
Anyone have any ideas? Because I'm out of all of them, and so is most of internet.
TL;DR - Adb devices detects phone while booted in OS, but not in fastboot. Tried all methods, nothing works. Going to do lock bootloader then unlock it and try again, if not that then going to do a clean wipe and install the community build again, hoping that would work. Should I?

I am having a similar issue. I have a brand new OP3. Everything stock. I'm attempting to unlock the bootloader and have found that while ADB recognises the phone, Fastboot doesn't. I'm pretty sure it's a driver issue and I have no idea how to fix.

I'm afraid you've missed the point, my friend.
If the phone does not get detected in the fastboot, it means I cannot flash anything, period. No original TWRP, no modified TWRP.

I had this exact issue and fixed it.
Fastboot would never see my device, no matter which driver package I tried or no matter how I tried to install or force the correct drivers. Turns out Windows 10 (and Windows 8) has a feature that completely prevents installation of unsigned drivers, which blocks the fastboot driver. If you're seeing "Kedracom" or "Android Device" in the device manager, then your driver is NOT actually installed. This is true even if Windows doesn't throw you an error message during install, or if you appear to force the installation. Even though it looks like you're doing the install correctly, Windows just ignores your unsigned drivers.
You need to temporarily disable the security feature to permit installation of unsigned drivers. This involves invoking a special restart function. Here's the howto for Win10: http://www.howtogeek.com/167723/how-...igned-drivers/
Once you've done this, on the next reboot you can do a forced install of the unsigned fastboot drivers you downloaded for the OP3. And simply rebooting your computer restores the security feature.

It's mostly because of the windows security over unsigned drivers.. Try the above method or just the cmd way..

OnePlus 3 fastboot driver issue

I had previously rooted my OP3, but accidentally updated it with the OTA open beta update, losing twrp recovery. I'm finding it incredibly difficult to flash twrp again to reroot.
The bootloader is still unlocked, and USB debugging is on with OEM unlocked, but I keep getting FAILED messages when I attempt to flash. "fastboot devices" shows the device (as a series of numbers).
I've tried using the OnePlus3&[email protected]_radaideh, but when attempting to flash it shows the below and then fails:
error: no devices/emulators found
I couldn't get it to work on my computer at home (win10) and read about problems with the OP3 drivers being unsigned (even with driver enforcement off). I'm also struggling on win7 - for some reason, the driver is listed in the Device Manager under the hardware group TP-LINK Android Phone and I can't get it to work using the OnePlus Android Bootloader Interface (under OnePlus, Inc.) or the Android Bootloader Interface (under Google, Inc.).
Could anyone suggest anything I should try?

Win10, Update & Security, Recovery, extended Start, there disable driver signing and then do your thing. Don't reboot or signing is active again.

Did you use the drivers coming with the phone on a emulated CD drive? These worked very well for me in the past.
EDIT: Yes, Kedacom problem is nice. But changing the driver to the unsigned one manually worked for me in the past.

Yep I was here aswell. Boot into driver signature mode and install the proper drivers. If you connect your device you can change the drivers. I don't have a PC next to me so I can't give you exact steps. The unbrick tool has the proper drivers, just follow the first few steps of that instruction to get it to show up as Qualcomm or something else as long as it isn't Kedacom.

If you want helpful responses you have to be more specific. Assuming you have the fastboot files installed on your PC/laptop ... What LG G4 model? What software version? Bootloader Unlocked? etc.
Assuming you have installed on your PC/laptop LGMobileDriver_WHQL_Ver_4.2.0 available for download from the LG US site as the Windows driver can create issues, have you tried downloading and installing the "Official" TWRP app and installing that way?

I have minimal adb and fastboot installed
device is h811 20v
bootloader is already unlocked
and yes I'm using LGMobileDriver_WHQL_Ver_4.2.0

If you want helpful responses you have to be more specific. Assuming you have the fastboot files installed on your PC/laptop ... What LG G4 model? What software version? Bootloader Unlocked? etc.
Assuming you have installed on your PC/laptop LGMobileDriver_WHQL_Ver_4.2.0 available for download from the LG US site as the Windows driver can create issues, have you tried downloading and installing the "Official" TWRP app and installing that way?
Suggest if you are still having problems, you head over to: https://forum.xda-developers.com/g4/development/recovery-twrp-3-touch-recovery-t3442424

I have the right files, when I get into adb reboot into bootloader
it no longer recognizes the device. I cannot flash twrp

After reboot into bootloader, open your "windows device manager" and see if windows detects your device properly.

Don't allow Windows 10 to update your drivers - you can set that up in Windows. Google it for the how-to.

The device type changes depending on "how" its connected. Windows can "see" it as a ADB device, MODEM, etc...
With the phone connected, uninstall all device related on windows device manager, refresh the device manager for it to detect the phone as it should be (as you need it to be detected).
Sometimes its needed a manual device driver install. Happens some times to me, unfortunately I don't remember exactly how I do it because the issues (when it happens) are kind of random, so, I need to "understand" what is going wrong and fix it.
Just to tell you that is nothing unfixable on the procedure, you just need to have patience and find out how windows is supposed to detect your device.
If you don't find out by yourself, tomorrow (Monday), I'll try to see on mine how it should be detected in fastboot mode and tell you. Today its already late for me...
Good luck

everytime I boot into the bootloader the driver stops working.. when I boot the phone normally windows doesn't recognize my phone. it is unknown, so I remove the driver, reinstall it., get into bootloader and same issue persists "waiting on device:" I think the lg driver keeps crashing or it is windows issue
will try again tomorrow

Your device should be seen as "LGE Android Phone" (if your lg drivers are good).
Now gonna be tricky because my OS is in Portuguese, I don''t know exactly the path name in English... use your imagination
Connect the device on a USB 2 Port !!!
In windows device manager, select "update driver", "search software on the computer", "allow to choose from a list of avalable drivers". unmark the "compatible hardware" and find on the list the needed drivers. If the "LGE" drivers don't work, try to download Universal ADB Drivers, maybe it works.

I'm thinking it could be a corrupted LG driver. Download another from the LG US site, ONLY. Uninstall the one you have installed now, reboot and install the newly downloaded one. Then connect your phone and see if it is recognized and shown correctly in Windows Device Manager. Also, in adb type lsusb and see if the phone is listed in the output.

Boss, no need to struggle with this ADB anymore.. there is a tool called FWUL which was created for people who have driver issues... Check it out here:
