[Q] Help unlock a noob's bootloader!

Hey,
I've been tinkering with my Nexus S for a few hours over the last couple of days, and I can't seem to unlock the bootloader. I've tried Googling the problem, but I'm having no luck at all.
I think I've installed all of the drivers correctly; when the phone's on, and I type "c:\android\android-sdk\platform-tools\adb devices" in the command prompt, my phone's serial comes up.
Then, and here's where I'm stuck, I shut my phone off, and restart it in fastboot mode. At the bottom of the list on the top it says "Lock State - Locked", I assume that's what I'm looking to change? From here I've tried unlocking it, and I've got the command prompt to say "waiting for device", but nothing happens with my phone. Even when I go for 'fastboot devices' nothing happens, it just skips to the next line.
I'm using 64-bit Windows 7, if that helps, and I'm very new to the command prompt.
I'm sorry if this is a duplicate post, I've spend the last half hour looking for a solution. Any help would be greatly appreciated.

I had the same problem. There is a decent guide at androidcentral that I followed.
One thing I had to do was install some drivers. I know this is going to sound crazy - but I kept reading that if you install the free version of pdanet -it has the drivers we need. So I finally just broke down and installed it and then adb worked in bootloader.
Hope that helps you a little.

[Q] super cid issue/ adb issue

i was going to s-off the this morning and flash illusion 2.0 but instead i am beating my head off the keyboard. i have been reading all day. i have like 12 tabs open and my main problem is that adb isn't working. not sure what i'm doing wrong. i need to get to supercid. instructions seem easy enough. i go to command prompt, change my directory, everything good here just as usual. when i type "adb shell" i get "error: device offline" don't know what i'm doing wrong. thanks in advance.

I had the same problem. First make sure ADB debugging in advanced options is checked. Next try booting into fastboot. If your on stock try putting it into charge only mode. Try the multiple different ways

do you mean usb debugging? or is adb debugging different? because i don't see adb debugging anywhere.

Check these things right here in the picture. Have USB debugging enabled and select root access and choose apps and adb

It's usb debugging that you need to check. You mentioned that you are on a custom rom ... Is it sense based or aosp? I was still on the stock ics rom when I changed to super cid. Everything went just fine, although I didn't proceed to do Facepalm s-off immediately. I did flash cm10, and came back to finish s-off a couple of weeks later. Nearly drove myself crazy, until I realized it works best when done on a sense rom. Flashed a stock rooted rom, and it literally took about 10 minutes to finish s-off. Restored my cm10 backup, and all is well.

I really appreciate the info. I'm on bb8, which isn't sense. I have USB debugging on. Should I be on a stock rpm to get supercid or just for s-off? My problem is adb won't my phone.

ok so, back on task...i can not get adb to work. i'm trying to get supercid. i can't find anything on adb. i get "error: device offline"

what do you mean by tried putting it into fast boot? & by that i mean i thought it had to be in fastboot. also, i believe i have sdk set up but that's maybe where i'm going wrong. in cmd i actually got it to say "daemon started successfully" which it's suppose to, but then it said "error: device not found" not sure what i'm doing wrong.

Fast boot is when you boot into boot loader using power + volume down. Once you get to boot loader there's an option for fast boot use you power button to select it

i serched the android sdk guide and it looks like i have everything in order. i will dl the gn toolkit. also, i've heard that some things work better with a sense rom. i did switch to trickdroid, which has wifi issues and will not be a daily driver, but i can't remember if it was with scid or s-off or something else.

Unlocking bootloader

So I was just trying to unlock my boot loader of my nexus 5 using to wubfresh toolkit. But I am having a problem, I am not getting the option on my phone to always remember my computer. And this is causing the program to not work. I have tried to reinstall the drivers and it still will not work. Does anyone have a solution.

You might need to update the Android SDK on your PC.

Still have not found a solution to this .http://gyazo.com/3fbc8ec1a9ff3a1dadfc8a1fdcd8edc1-- this is a picture of what is suppose to come up and I am not getting it.

Rooting possible with a command terminal?

Just got my nexus 5. Went to get my laptop only to find out its been stolen. Is there a way to root using the command terminal in say jumpy apps?
I'd hate to have to buy a Laptop just to root this phone. The root browser seems to allow access to all the relevant files. Anyone tried this?
Thanks.

Afaik, you'll need a pc to unlock the bootloader. From there I suppose you could do the rest on the phone using dd commands to get a recovery on. But since you'll need the pc anyway you might as well use it to get the recovery on.

How do you go to get your laptop to find out its stolen? Lol

You will need a PC with working adb connection to unlock the bootloader

Why don't you just borrow someone's pc or go to a internet cafe?

You could always try a library. All you need to do is download fastboot, run "fastboot oem unlock" and reboot. You can then do the rest on your phone. It shouldn't take you longer than 10 minutes.

ADB and Fastboot go hand and hand from my knowledge. Even a slim non full version SDK still has ADB .

What do you mean "hand in hand"?
They're both command line platform tools offered in the android SDK but thats about all they have in common. One is a minimalistic "linux shell" for interacting with the android kernel (adb) where as the other is a tool that manages the fastboot functions of the bootloader.

Correct.
You will need to have USB drivers, of course to use fastboot, which are often referred to as "adb drivers" but not the adb binary/exe itself

Last Internet cafe closes here and pale think rooting will damage their LT! The ones I asked.
I only posted this out of desperation. Library computers are locked up so can't accept drivers.
I've been rooting since the early days and I did a Samsung g2 without a computer. The boot was open. I just put the su, etc on the card and rooted it. As it was pre owned not sure if it had been unlocked or was like that from new. I've come from the nexus 4 mainly because of 4g.

Do you have another device that supports USB OTG? It can do everything the laptop can with ADB and fastboot. The ADB binary is shipped with android, you'll just need the ARM fastboot binary.

[Q] Nexus 5 Brick/Soft Brick

Hey guys,
New to this forum so I hope someone can help me out with this issue.
Status: Bircked/Soft Bricked..
CM11
Running ART
TWRP installed
Rooted
Unlocked bootloader.
CM11 has been running fine for me for quite a while until i switched it over to ART. It ran for a few days and then all of a sudden..BAM... it dies and wont boot into the OS or the TWRP now. I can get into the CM11 start screen and even to the point where it says"updating apps" it boots into the phone but starts giving me phone errors and then reboots itself into the CM11 logo screen..yadda yadda yadda.
Also, I cannot boot into TWRP. I get to the TWRP screen and it freezes on the TWRP initial screen, the screen without the options.
when I run fastboot and run a "Adb devices" in the command prompt i get the "emulator-5554 offline" error.
I have tried flashing twrp and even CWM onto the nexus 5, nothing seems to happen
Im in a jam and i hope someone can help me through this.
Thanks guys

Hmm.Did it work for you?

Try flashing the factory image in fastboot.
Also, adb commands are not going to work in the bootloader. You need fastboot commands.

I don't think there is going to be a way. But I'd try this. Download the bootunlocker script from here http://forum.xda-developers.com/showthread.php?p=40409356
Also have the twrp recovery image on your PC. Then boot into the bootloader. Try
fastboot boot recovery.img. Where recovery. img is the twrp recovery image. If that works it'll boot into twrp.
If it works adb push the bootunlocker script to your device and install it in twrp

So just an update, they are going to RMA the device. I told them everything I did to it and they are still going to take it back. Let's hope it is that emmc flash memory, it should be covered under the warranty as a hardware defect. Well I'm assuming it is .
Thanks for the help, unfortunately nothing seemed to fix it. Ah well we tried. I will update everyone on the process, so ppl in the future know if Google will honor that warranty.
