Problem locking bootloader. - Nexus S Q&A, Help & Troubleshooting

Adb is saying that it doesn't recognize "fastboot" as a command. I haven't really use ADB since I got the phone in February, has there been changes to the commands needed?

I did a simple search and found this: http://www.nexusoneforum.net/forum/...-fastboot-devices-command-not-recognized.html
GL Hope it helps.

Problem is not it recognizing cause Adb reboot-bootloader works.

This used to work
Cd\
Cd androidsdk/tools/
Fastboot oem lock
Has something been moved? And if so what is the new path?

Make sure fastboot is still in your tools folder. With some of the updated sdk fastboot gets removed. If it's not there you can get it from the cm wiki and just put it in the tools folder.

The problem is that you think you need to run adb to get fastboot to work.
adb and fastboot are 2 separate programs. ADB is the Android Device Bridge where fastboot is another standalone command line program s used to directly flash the filesystem etc.
If you download the Android SDK now, it won't have fastboot included, so you need to get it from somewhere else, like the old CM wiki as crump suggested.
Once you have the compiled fastboot file, you can navigate to it from a command prompt and execute the fastboot commands

Thanks for the clarification. I really only used it once or twice when I first got the phone. And I just looked and I am missing the fastboot. I'll give it a shot.

In cm wiki there is only fastboot 32bit. I have 64bit, will it still work?

[Q] Installing Cyanogenmod, Fastboot wont work.

So, trying to root and install cyanogenmod on my friends Evo **** 4g 2.3.3.
Following instructions per the cyanogenmod install wiki and a few other places.
I am using linux for everything and have adb setup correctly. I downloaded the fastboot from htc's dev website. [Everyone links you to the website but forgets to mention that you have to create an account and click on 'unlock bootloader' and scroll through a few pages]
Anywho, I did that and extracted the file to my android sdk directory. {for me it's [androidsdk/platform-tools]}
Now, when I try to run the fastboot command after running the adb reboot command to get into the bootloader, it returns with an error. "Fastboot command not found"
Now, I double checked and I marked the permissions for the fastboot file to be allowed to execute as a program.
What else am I doing wrong? If someone that has done this before, could help me out, that would be fantastic!
Again, I am running on ubuntu 11.04 linux with adb set up properly. Thanks.
cehck to see if you are in the same directory as fastboot. If you are in the platform-tools/ directory, do cd ../tools
fastboot *command here

I was indeed in the same directory as fastboot, but fastboot would not recognize as a command. Even when I tried it with my atrix.
Try chmod 777 fastboot

[Q] Serious problem

Hi,
please help me! I hope it is not a brick.
I wanted to make full wipe. I made factory reset in recovery and then wiped sdcard.. Now I cannot boot ROM because there is no one and I have nothing on my SD. So I even cannot copy rom or backup back to phone.
Is there any way out? (
EDIT: I think I can push files (e.g. backup) through adb, right? I installed adb for dummies but when I want to execute SDKmanager.exe. it only opens black window and immediately closes it. I cannot continue

Access your commands through a terminal window, like start > run > cmd to get into the prompt.
and from there work your way to your directory where you have placed it, and execute the command from that directory directly.
..
Thanks!
In the end I used adb to push backup in recovery...
All this I did because I wanted wipe my device - today I woke up and got a call and found out that my earphone stopped working I am afraid that it is due to condensation and next oxidation... I did not do anything wrong but when you come from cold winter weather into a warm flat it can happen Now I need to send it and hope the warranty will pass..
Anyway, I was looking for complete unroot process and found several advices. I am not clever from them. Is it enough to flash stock ROM? Recovery will be removed as well??

Ok. I have everything done but the relocking. Could you tell me how shall I do this? I tried to write "adb reboot bootloader" and then " fastboot oem lock" but both case the command line responded something like that it is not internal command etc. (I dont have it in English) Cannot lock it

1.Switch off your phone
2.Connect your phone to your PC throught the USB cable
3.Switch on phone into fastboot
4.Provided that you have the driver for windows for the phone installed open Start/run/cmd (from your PC)
5.From the Android-SDK/platform-tools run the following "fastboot oem lock".
like :
C:\Android-sdk\platform-tools\fastboot oem lock
this will lock it immediately ...

it works only in "tools" and then it just says "waiting for device" and stucks When I tried "fastboot devices" it says nothing... I tried to reinstall drivers but maybe I have some old version? When I am in Windows copying files etc. it works well.
1. Make sure you open the command prompt IN in the folder with fastboot.exe.
2. Put the phone in fastboot mode.
3. In the command prompt type fastboot devices.
It will now show your serial number. If not its either you are such a noob that you managed to screw that up or the fastboot drivers are not installed. Or both.

OK. I really dont understand what could have been screwed up. Ok. It doesnt show anything. Just nothing. Cen you please send me the link for the drivers which should work? Maybe there is the problem. Fastboot drivers are something else than drivers for adb to be working? Because I dont know whats wrong. Thanks...

If you have i9023 you need to add a line into the sdk for driver. You can search the tutorial threads for it.

try this
just check if you have fastboot and adb on the same folder, when I've rooted mine's got this issue, if cmd report "the command is an external one" simply means there is no such program in the folder you are in
copy both adb and fastboot in tools and platform-tools too, so you can run the command in both folder
cd>desktop > cd android>cd android-sdk> cd tools (then run adb or fastboot)
cd>desktop > cd android>cd android_sdk> cd platform-tools (thr run adb or fastboot)
1. Find out exactly what phone model you have if you don't know already.
2. Do the same for your computers os . Including 32 or 64 bit.
3. Combine that info and search the forum or just Google search. How to install fastboot drivers for phone model in step 1 with the os in step 2.

Thank you all. I decided to unroot it and relock it using Odin software which was great and quick. So I am done.... Adb has a lot of problems with drivers, commands, paths. This way was much easier

[Q] Noob Root Walkthru

I am new to the ASUS family of tablets, and j just can't figure out how to root. I have rooted many tablets and installed custom roms before but the i cannot follow the how tos listed here. For one fastboot doesnt work on my computer. It opens and closes immediately. What i would like is a detailed step by step guide with a trouble shooting guide. I mean now i reading about downgrading, blob files and a few other things i never dealt with on my galaxy. Someone help......would love to root this thing. Email me if u want [email protected]
You need to run fastboot from the DOS Prompt
start run - cmd
then type fastboot command.
I take it you have unlocked your bootloader?
Check this thread, it has videos about rooting and whatnot, hope it helps:

Yes, Bootloader is unlocked. Ok, so I tried the flashboot command, so now what? I typed the command from the walkthru "fastboot -i 0x0B05 flash recovery recovery.img " but get an errorcannot load recovery.img. So what am I missing. I have the recovery image on my desktop.....
Put the recovery image in the same folder as your fastboot application and it should work.

....what fastboot folder? I installed the ADK per the instructions, I downloaded the root and recovery image. I looked in the system for a fastboot folder and do not see it. Plus when I try to type in the fastboot command now, it says it is not a recognized command. I am sure this is something simple, but I am just not getting it. Is there a more detailed step by step somewhere that will actually walk you thru the steps without assuming you know what they are talking about? I can root my phone, my galaxy tab all day long and install and change ROMS, but this one has me upside down.
When you installed android SDK and ran SDK manager to install the tools, it should create a "platform tools" folder. In that folder you should see "fastboot.exe." Put the recovery image into the same platform tools folder.
Make sure when you run the command that you are in the command prompt, and that you have navigated to the same platform tools folder. It should then recognize the fastboot command and flash your recovery.

Found the folder and it did have the platform tools in it but Apparently I have forgotten how to navigate in CMD, so I moved the folder to the current location CMD was at. I typed in the command fromt the walkthrough and I get "adbwinapi.dll" is not installed. Not sure if this is progress or not.....so now what.
That file should be in your platform tools folder as well. I think it's a driver issue. Is your tablet showing up in device manager? Does it have a yellow triangle? I'm not really an expert unfortunately, hopefully someone with more knowledge can jump in.

Ok, so reinstalled everything.....did a quick refresher on CMD directions and had it rooted with CWM in 10 minutes. I have been working in Android so long without the use of a PC that I forgot how to use the PC. Thanks for the help....now we wait for some nice roms.
Sweet, glad you got it, I've done this stuff a few times but I always have to refresh myself and take it slow on each different device.

You should not move the folder. This can cause all kinds of problems. in the cmd prompt just type
cd \folder\folder\etc.
The cd means change directory and you start off with a backslash to set the initial path to the root of your drive. if folder names include spaces then wrap the path with quotes, cd "\folder one\folder two\etc". the prompt should change from C:\windows or whatever to what you typed in.
if you've installed on a drive other than C: then first change to that drive by typing the drive letter followed by a colon, ie D:

ADB not recognized

So I finally undated my PC from Ubuntu 12.04 to 16.04. The good new is I have full MTP access to my G3 now. However, ADB is no longer recognized. ADB and Fastboot are located on a separate drive from the OS, so I am trying to run the same file from the same HD. Any suggestions?
You need to run adb in root. Are you doing that?

I did try that without success even though I successfully ran ADB without root with 12.04. Only Fastboot needed root.
For some reason the file is not recognized as an executable file. Below is a screen copy:
Code:
$ ls
adb fastboot twrp-osprey-3.0.0-r2.img
commands.txt twrp-osprey-2.8.7-r5.img twrp-osprey-3.0.2-r1.img
$ adb
The program 'adb' can be found in the following packages:
* adb
* android-tools-adb
Try: sudo apt install <selected package>
$

I have not even got that far. See post above, "adb" is not recognized. I would rather not install the adb development package if I can avoid it.

The commands is not my issue. I have a list of commands I have run successfully many times. My issue is with the new OS (in the same PC) not recognizing adb. When I boot to the old OS, no issue, back to the new OS, command is not recognized..
My list of commands is as follows:
Code:
adb devices
adb reboot bootloader
sudo fastboot devices
sudo fastboot boot twrp-osprey-3.0.2-r1.img

Re-reading your reply, I think you mis-read my code box. Next to the dollar sign my command "ls". Below is the OS response. Next $, command is "adb", and below the OS response.
I figured it out. So in Ubuntu 16.04 my command needs to be:
"./adb"
where in 12.04 "adb" worked.

This implies execution from the current directory... Are you sure you don't have multiple 'adb' executables installed? Check the command 'which adb' to see.

adb doesn't work in bootloader mode, that is when you use fastboot... I think you should review the process involved in installing recovery.

Seems like youre in the wrong folder. Try to navigate to your download folder with the command cd
You can also send pictures in here
You have to open a Terminal window in the same folder where you have adb and fastboot.
Also, on OSX, the commands have to be preceded by ./
For example:
./adb devices
./fastboot boot twrp.img
Done it thank you.
I did the 'cd' command.
Then dragged the img. file from Finder to the terminal window. Then put the 'fastboot boot' command in front of that. It worked obviously.
I was unfamiliar with the file location name. This seems an easy way for someone that doesn't have a clue like me. ??
