bro this question was answered heaps of times..
search before posting..
Also this is supposed to be in the general section not
development..
Anyways go into clockworkmod if you can't connect to
pc and wipe everything and reflash with Recovery.

there was a post of how to make fastboot recognizr your device
but i forgot because fastboot works fine on linux
maybe if you find

Try the recovery, i had this problem as well!!
uninstall all drivers and reinstall them..
After that go to fastboot and type
fastboot -w
fastboot reboot

Press Power+Volume key to access download mode. Computer will now recognize your GT540.
Reflash .kdz

Hold the HOME button along with the POWER button while turning on your phone. You should encounter recovery at some point. If not, flash a recovery rom by typing:
Code:
fastboot flash recovery <image_name>
Replace <image_name>, with the recovery image and remove the brackets.
So for example:
Code:
fastboot flash recovery recovery.img

The 'display initialize' thing is a part of fastboot. Do the commands when you're in fastboot.

er dudes remember that the blue screen and white text is only there if you use mur4ik's bootloaders and not the one you get from the kdz

If you have blue screen its not dead
sudo ./fastboot -w
sudo ./fastboot flash boot boot.img
sudo ./fastboot flash system system.img
sudo ./fastboot flash recovery recovery.img
Maybe its your adb server cant remember the exact command but its something like
sudo ./adb kill-server
sudo ./adb server
Or something along those lines look it up on google its the command to restart the adb server if you use more than one device or do alot of work with adb sometimes it will show it cant connect to the phone when really it can it just needs to be rest because something has screwed up on the system and or phone.
Hope this helps and good luck if you still have problems give us a few more details and what happend where but your gt540 is nowhere near broke trust me.

You think that I should reinstal the adb server (or the complete adb with sdk)
Killed the server,and startet it again,but with no response from phone ...
I have reflashed the phone with V20D,and now it stucks on android logo ...
The fastboot is still not working

reinstall LG drivers or whatever drivers needed for our phone and try fastboot again .

Fast boot drivers are missing from your computer, Vernica's pinned post with lots of guides will point you in the correct direction.

ADB recognizing issue

So I am having a lot of problems with trying to root my nexus 7. I'm pretty sure it boils down to a driver issue but I'm not sure. I have tried installing the correct drivers over and over again also uninstalling other hardware manufacturers drivers and I cannot get adb to recognize my device when it is shut off and in the boot loader.
When the tablet is on and I have debugging on, adb shows up and is recognized, however my problem is that whenever I reboot into the boot loader I lose adb recognition. So therefore I can't root or do anything else. Fast boot commands work fine its only the issue with adb.
If anyone has any suggestions as to what I can do I would really appreciate it. I don't know if its just a hardware issue or something I am doing wrong on my end.
This is also not my first time manually unlocking/rooting a device

When you initially connect, the device shows up as a "Nexus 7".
When you reboot into the boot loader, the device name changes, and there is no driver for that device.
As far as I could tell, I would have to do the root process under Linux to avoid this issue.
As for me, I just ignored the issue. By the time you reboot the bootloader, you are already rooted.
The only thing you do after the reboot is rename a file. For now I am missing that step...

Yeah I'm using windows xp. When its in boot loader it does change names. I can unlock the bootloader via fastboot but can't do anything with adb. Lol I don't know what else I can do, I'm at a loss.

Like I said - I think you are done...
Install a terminal on the Nexus and see what it says to "su". I use one called "terminal emulator". Works fine.
I think fastboot uses adb.
If you connect your Nexus, and type "adb devices" in a command window what does it say?

I believe it says devices attached or something like that. (Not at my computer) but doesn't give me a serial # like I think it should.

If you do not have USB Debugging checked, "adb devices" will just show the List of devices line.
If I set USB debugging on, "adb devices" also shows the Nexus serial number.
If you don't see that, I would double check the device driver you are using.
Under Device Manager, Android Phone, Android Composite ADB Interface it shows:
Driver: Google Inc.
Date: 5/24/2012
Version: 6.0.0.0
Digital Signer: google inc.

Well if I have USB debugging on and tablet on and do adb devices I get the serial # but once I go into boot loader and do adb devices I don't get the serial #.
For device manager I can choose adb interface or adb original interface. I'll have more info when I get out of work and at my computer. Do you have a link to the drivers you used? Or where to find them. Because I have tried a couple of different drivers posted around to no avail.
BTW thanks for helping me out.

I would not use any posted driver - you don't know where that thing has been.
Download the SDK from Google; the correct driver is in there.
Just point the device manager to it when you install drivers.
There are a lot of good descriptions on installing drivers in the other nexus forums
But - again - I think your device driver is fine. You will not be able to talk to the Nexus from ADB after you boot the bootloader
Bootloader has a different device name which ADB can't use under Windows.
Use Linux if you want to do that.

ok, so pretty much what happens is when my tablet is powered on with usb debugging everything is fine and ADB is recognized. Now my problem seems to be when i reboot into the bootloader it seems as though the drivers dont stick and it asks me to install the drivers again and this is where i have had all of my issues. When i type in adb devices in, it just tells me "list of devices attached" and wont let me do anything else (fastboot works). Like i said i was able to unlock my bootloader but i cant flash recovery or do anything else.
When i go into device manage to select the drivers it gives me the option of choosing between adb interface, adb bootloader interface, adb orignal interface and nexus 7 bootloader interface. I have tried all options and nothing seems to work. I have tried multiple usb cords and ports.
If anyone else has any suggestions it would be much appreciated.

I didn't read through everything but your initial problem is adb doesn't work in the bootloader that's where you use fastboot commands either boot into a custom recovery or just boot up normal and make sure debugging is checked.
Try running fastboot devices and see if it shows up. What you need to do is have bootloader unlocked and dismiss the super user zip floating around here pot that on sd card download cwm recovery image floating around boot into bootloader then
fastboot devices
fastboot flash recovery name_of_file.img
fastboot reboot bootloader
select recovery from the menu
Flash the super user zip
Or download a rom that has root and put that on sd card instead of super user zip and after doing the steps above then selecting super user zip select the rom you downloaded and flash. If you're on Linux run sudo first.

-setup adb

-open command prompt and type:
Code:

-if your phones serial number shows up, its recognized. Then you can push a rom back onto your phone and flash it using:

[SOLVED] Z1 not showing up in Linux ADB devices

hi,
trying to flash the breadcrust recovery using my linux pc, but the Z1 doesn't appear in the list of devices when running adb devices. Image attached. Normally I would get a request to accept the RSA key for a trusted pc when enabling usb debug. But I don't get this option.
- Adb tools are loaded and working on my linux laptop
- My nexus 7 responds to ADB devices and shows up ok
- tried on wifes windows laptop with adb/sdk tools loaded and no joy there too
- i have developer USB debug options enabled, i've tripple checked this
could it be the cable? I'm using the one which came with the phone, so that should be ok?!!
cheers
SOLUTION - I ran this One Plus Two script modified with the Z1 device ID and now I can see my device in adb devices and interact with it. I get the SHA screen to allow access and can run commands from linux terminal. YAY!
See the attachments for script.

I think it´s a driver fault. Did u install them in windows?

im using linux, i dont get any rsa pop up confirmation either!

But u said, that u tried ur wifes Windows notebook. Did u install the drivers there?

ADB doesn't work for me, too. I work around this problem by booting into recovery (simultaneously press Vol+ and Vol- and Power until phone vibrates) and choose "Boot to bootloader" from there. After rooting I installed "Power Toggles" from Play Store and use the toggle to reboot to recovery or bootloader.
By the way, when I boot into recovery, I'm able to ADB sideload. So I don't think there's a driver issue.

ok some progress.....
got the trusted device RSA screen to appear on my wifes windows pc. i could then run adb devices and see the device.
I could run adb reboot bootloader, but the device doesn't boot into fastboot, just reboots as normal!
I could also hold down up/down volume buttons and get into the bootloader, but again the device isn't picked by any fastboot oem checks for unlocking!!
arrrgh!!!

You'll have to add -i switch followed by the device ID to your fastboot command. I don't have it at hand, so just read the TWRP thread.

ok! Some progress...ish.
running "adb reboot bootloader"command in windows worked when I switched Cyanogen recovery updates off in developer options. The Z1 reboots into bootloader.
Running "fastboot -i 0x2b4c oem get-device-info" returns nothing just "....."
So I tried "fastboot -i 0x2b4c oem unlock" an error returns cannot unlock use command "fastboot -i 0x2b4c oem unlock-go" which works. The phone wipes data and reboots back into OS.
I re-enable the developer options and adb debug. and reboot into bootloader
Run "fastboot -i 0x2b4c flash recovery z1.twrp.2.8.7.0.By.Breadcrust-UPDATE3.img" - some time stats are retunred and OKAY message. But when I boot into recovery it's still the cyanogen stock recovery. not TWRP.
weird!

Your commands are simply wrong, thats why they don´t work.
It is:
fastboot -i 0x2b4c oem device-info
fastboot -i 0x2b4c oem unlock-go
Run "fastboot -i 0x2b4c flash recovery z1.twrp.2.8.7.0.By.Breadcrust-UPDATE3.img" - some time stats are retunred and OKAY message. But when I boot into recovery it's still the cyanogen stock recovery. not TWRP.

Flashing does NOT work on the international version, you have to boot into it directly from fastboot.
fastboot -i 0x2b4c boot z1.twrp.2.8.7.0.By.Breadcrust-UPDATE3.img
Should be correct instead of the flash command.

What made the change? I was able to see the RSA screen only once, but after device restored to defaults I can't get it back. same drivers installed, and it appears in the device manager.

I honestly don't know, it just worked after many attempts. I read somewhere about USB 3 ports with Linux so might be the same for windows?

It's an USB 3.0 issue. Plug the phone into an USB 2.0 port, or an USB 2.0 hub plugged into an USB 3.0 port and it will magically start working. God knows why this is the case...
Ironically, fastboot works fine even on USB 3.0...

For to be able to boot (not flash) the TWRP recovery you shouldn't need to unlock bootloader. Am I right?

Booting should work.
At least it worked fine on other fastboot capable devices I've had in the past.

Okay, I have found out that it is impossible to boot from TWRP as log as the bootloader is locked. It just took me 2 hours to setup my phone again after unlock.

Have a look at this thread, I am going to give it a try later.
http://forum.xda-developers.com/showthread.php?t=2408802

This did the trick on Linux (Ubuntu):
- run on terminal "sudo gedit ~/.android/adb_usb.ini"
- put "0x2b4c" in
- run on terminal "adb kill-server" and "adb start-server"
And run the fastboot commands with "sudo".

Working ADB Driver?

Hi guys!
I am trying to flash the factory OS downloaded from the dev website, however I have a problem.
When the phone is booted in Android the ADB Interface is recognized without a problem.
However when I reboot to recovery to flash the FW Windows 10 (latest CU version) does not recognize ADB Interface and says This Device Cannot Start Error 10
I have tried these drivers:
adb-setup-1.4.3
SAMSUNG_USB_Driver_for_Mobile_Phones_v1.5.33.0
latest_usb_driver_windows /google driver/
OnePlus+5+USB+drivers+-+Technobuzznet
Nothing has helped, the issue remained the same.
Any suggestion what can I do to get OP5 ADB working when the phone is in Recovery ?
Thank you!

same problem.
fix for it -> use linux
setup vmware, install ubuntu
when everything is set up connect device in fastboot mode
open command line:
sudo apt-get update
sudo apt-get install adb
sudo apt-get install fastboot
now you can make adb and fastboot commands, don't forget the sudo before the command e.g.: sudo fastboot reboot

I made the mistake of wiping my entire device when going to do a clean flash so the only thing I could access was recovery. I had no issues with using adb to sort out my mess in Win 10. The last phone I had was an old HTC that I was using between getting my OP3 stolen and the OP5 release and for that I had HTC drivers installed.
Not sure if that is a solution that will help you, but just putting it out there.
