help with unlocking bootloader...

I have a LTE gnex. I am having problems getting my bootloader unlocked.
If I attempt to use fastboot commands at all I get the error 'fastboot is not recognized as an internal or external command, operable program or batch file.'
If I attempt to use adb devices while I am in fastboot it says "List of devices attached." If I use the adb devices command when my phone is turned on it lists my device like normal.
I feel like I am so close, but yet so far. Any ideas?
EDIT: I'm attempting this on XP, and I am on 4.0.2

I am no expert in these matters, but a few things come to mind:
1) have you got all the proper drivers installed?
2) in the cmd prompt, are you in the directory where fastboot.exe is located?
Have you followed this thread? I'd recommend downloading superboot, extract the contents, go into that folder, and then use: 'fastboot-windows oem unlock'. That should definitely do the trick. Good luck.
EDIT: I don't specifically know all the differences for the GSM/LTE/CDMA versions, but the above should be okay for all versions. To root, and install recovery, on CDMA versions, check out this google+ post.
EDIT2: Also, this thread may be worth looking into.

Assumptions:
- your drivers are loaded properly
- file names are: adb.exe and fastboot.exe
1) open the folder w/ ADB and Fastboot located in them.
2) shift + right click in any open space in the folder - choose: "open command window here"
3) type in (minus the quotes): "adb reboot bootloader"
4) the phone will reboot in the bootloader screen
5) type in: "fastboot oem unlock"
6) phone will ask you are you sure? - use the volume buttons to make the selection say "yes" and press the power button.
7) the phone will unlock and restart. the restart can take as long as 10 minutes or a tad bit longer... do NOT be alarmed!
if this doesnt work for you... either your drivers arent fully installed or your adb/fastboot programs are duds.

just open command prompt manually and then go to folder. Eg 'start' -> 'run' -> type 'cmd' and hit enter. Then cd c:\path to folder\ etc.
edit: plus, i gave you a few links to other threads. I really recommend to follow the steps described there if you haven't so far...

hot to install kernel using mac lion?

i read through all the posts and am having trouble. i have a macbook now and my htc one v is stuck in a boot loop. i need some simple instructions or a link to how to flash a kernel on mac. i have googled it ect and i may be dumb or i cant seem to find the answer and everyone is always so helpful here and im getting frustrated. thank you so much. my phone is already rooted with a custom recovery. its a virgin mobile us

Go developer.android.com and download the SDK & move it to your home directory ("~" or /Users/<username>)
Go to <sdk-location>/tools and launch "Android"
Download the platform tools
Open terminal
Open Finder to <sdk-location>/platform-tools
In terminal, type "sudo cp"; drag adb from the Finder window into the Terminal window; type "/usr/bin/"; hit enter
Enter your password
Repeat the above three steps, but drag "fastboot" instead of "adb"
Close terminal
Open terminal (it sounds weird, but just do it)
Now, and forever, do this to install a kernel:
Download kernel
Connect phone to computer
Make sure USB Debugging is enabled (Settings>Development>USB Debugging)
In terminal, type "adb reboot bootloader"
In terminal, type "fastboot flash boot"; drag in the kernel from finder; hit enter
Examples:
Code:
sudo cp /Users/Username/android-sdk-mac/platform-tools/adb /usr/bin/
sudo cp /Users/Username/android-sdk-mac/platform-tools/adb /usr/bin/
adb reboot recovery
fastboot flash boot /Users/Username/Downloads/boot.img

No problem! You may want to clean them up a bit; I was in a hurry when I typed those.

sure thanks ill credit u for it

It's very simple. Follow whatever instructions are for the kernel, rom, whatever, but add "./" in front of the commands. So "fastboot flash boot" becomes "./fastboot flash boot"

No! That only works if he has done
Code:
cd <sdkdir>/platform-tools
other wise, it will fail and confuse him even more. Doing cp to /usr/bin/ will allow him to never have to do "./" before the command.

Ok ok calm down. I do it my way multiple times a week, I've never had an issue. Sure I have to cd into the directory, but that's only one more line of code. If your way will be easier then cool.

[GUIDE] How to S-Off and install ENG hboot to your One V

Disclaimer:
I (or anyone other than yourself) am not responsible for anything that goes wrong with your phone. This process is very safe, and the likelihood of bricking your phone is so small that you have a better chance of flying to the sun without a rocket. If you read the guide here closely and do not alter from it in any way, your phone will be S-Off and fully ready to have fun with.
#2
I did not write any code or have any involvement with the development of rumrunner. If you want to donate to someone, donate to them at [email protected] via PayPal. Really guys, I didn't do anything more than test. ​
For Linux:
For Linux, you do not have to install anything to your hard disk. In fact, you only need a USB port or CD-ROM drive. Ubuntu (32bit) is the recommended distro, however others will work. This guide will only use the Ubuntu given below, for universality purposes.
Downloads:
Firstly, we need to get some important files. Please download all the files given below
Ubuntu 13.10 (32bit)
rumrunner (Go to One V Linux at the bottom of the page)
hboot mod (For your corresponding device, for more info see Device Identification section)
NOTE: Some variants do not have Hboot mod yet. Please be patient.
ADB and Fastboot
Unsecured boot.img
If primoc or if primou (DONT have a stock boot.img yet... can someone send that in a PM please)
Now that you have all the files, boot into Ubuntu. I will not go into detail in how to do this, as it is well documented elsewhere.
Once in Ubuntu, open a terminal for usage.
Now minimize this and place the downloaded files onto your desktop.
unzip the adb_fastboot_linux.zip file to the Desktop
Un-tar and Un-gzip your rumrunner file to the desktop. This can be done by double clicking the file, then clicking extract.
unzip the adb_fastboot_linux.zip
move Primoc_Unsecureboot.img into adb_fastboot_linux/
go to your terminal, type "cd ~/Desktop/adb_fastboot_linux/ && chmod a+x *"
now type the command "sudo ./adb reboot bootloader" (if you get waiting for device, enable USB debugging in developer settings)
If you're not unlocked, unlock at htcdev now... Else, continue
Run the command "sudo fastboot flash boot Primoc_Unsecureboot.img" then "sudo fastboot reboot"
Now....Type in "cd ~/Desktop/rumrunner_primo_0.5.6" and press enter.
Now, type in sudo soju. Respond to the prompts within the program and follow all the directions.
You should now be S-Off... want more power, well lets get it.
If your device has a hboot mod follow the following commands.
move the hboot_rumrunner_primoc.zip into adb_fastboot_linux/
"sudo adb reboot bootloader"
"sudo fastboot erase cache"
"sudo fastboot oem rebootRUU"
"sudo fastboot flash zip hboot_rumrunner_primoc.zip"
OR if it primou
"sudo fastboot flash zip hboot_rumrunner_primou.zip"​
Congradulations, you are now S-OFF and can flash kernels in recovery. You also have flat out ultimate control over your phone; however, tread carefully. With great power comes great responsibility.
NOTE: Windows coming soon.
Device Identification:
It is important to know which device you have with the S-Off process. If you do not know what device you have, you can severely damage your device, possibly bricking it. To prevent this, follow the steps for identification below.
Unplug phone if plugged in
Go to settings>power>fastboot(disable)
power off phone completely
once phone is off, press volume down+power until bootloader appears
look in the top left corner, you will see either Primou or Primoc
If primou appears, you are GSM if primoc appears you are CDMA

Im leaving this thread closed until I get a chance to write up windows as well

How to open an "adb shell"?

On the official cyanogen mod guide for the LG G3 this is stated:
Now, open a command prompt window or terminal window and open an "adb shell"
How is this done / what is meant by it?

Download the drivers for LG G3, download the adb from Google, connect your device to computer, open command prompt, navigate to adb.exe or make a path in computer settings, verify that device is connected with command: adb devices, if your device is listed continue with command: adb shell, copy whats written in the guide you found.
Or save yourself the trouble if you aren't good with cmd and download flashify from Google Play, download the latest TWRP and flash it. Of course this will work only if you used the benders autorec app on lollipop otherwise you will get secure boot error.
But if you are on kitkat you don't need to install benders autorec, just download TWRP and flash it either with flashify or with adb.
Also if you dont want to use computer you could install terminal emulator from Google Play and you wouldn't need to use adb shell at all. Just write the stated commands, that is:
su
dd if=/sdcard/twrp-d855.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery
Happy flashing.

LETS GOOOO!! HEROOO!! Super easy and working on the latest December 2022 update! Felt way safer as well, not so much concern over twrp as we only booted into it, and then I just used the standard magisk and it worked excellent without worrying about all types of patches and versions aside from the latest twrp for android 12 from @JengaMasterG!
Thank you! I think the renaming the magisk file from apk to zip was probably what I was doing wrong trying to follow the other methods, on top of driver errors, that were solved by uninstalling all the drivers for the duo on my surface pro, which revealed a native 'Surface Fastboot' driver. Combine that with the 15 second ADB and it's .bat ready to go command line interface, idk... it wen't so smooth and worked perfectly.
Now I can try to see if I can improve my experience with some go to methods.. I really want to enable immersive mode and hopefully increase overall volume, if possible (many devices this can be done with engineeringmode, idk yet but hopefully it does have one and hopefully I can also calibrate the gyroscope)... obviously adblock without vpn is on the menu.... can utilize the full autoruns app to stop apps from starting up at boot like in windows... and then get into some other customizations.

Hello! I'm rooted, but I can only read and can't write. I am Android version 122022.821.13 of Att.
So I can't delete the apk inside the system directory

Newer Android versions, especially stock ROM, generally doesn't let you write to the system partition. Only ROMs can do that, unless you can find a way to change the partition permissions. Root alone will not allow it, no matter what you do. I used to know of a TWRP script to fix that and make the system writable, but it doesn't work on andorid 11/12/13 anyway
