Unlocking bootloader - General Questions and Answers

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.

[Q] Help rooting 2.3.4 At&t

Finally jumped the ship from iOS to Android. I've been looking around the forums and all over the internet, but I can't seem to find a way to root my phone? I'm on 2.3.4, i9020a, and build number is GTJ61. I've tried multiple guides, but none of them seem to work. Is it because I'm on Vista, or am I just missing something here? I'd appreciate any help.

Something tells me you are missing the drivers.

I just got mine (identical to your unit) and rooted successfully. Did you follow every step in the guide?
Yes, whenever I try fastboot OEM unlock, it just sits there, waiting for device.

"Waiting for device" I do only remember from two situations:
a) missing USB drivers
b) haven't turned on "USB debugging" in Android settings (Menu > Apps > Development)
b) being the more probable reason
I've turned on USB debugging. Maybe I don't have the correct drivers installed?

that's probably it, or you might have fastboot in the tools folder of the sdk. I had to move it into the platform-tools folder to get fastboot to work if I remember correctly. type fastboot devices in command prompt to see if your phone is listed there.
Its not listed there.

Cant seem to root, someone pm and help me

I've tried the new supertool v3 and the aahk hack and it doesnt seem to do anything. It might be my computers fault cause it keeps giving me weird errors like my usb device has malfuctioned or windows doesnt recognize it. I'm lot and would like some assistance if someone could help
thanks,
mike
finally figured out it was my other computer so i moved to a different computer and am using the supertool hack and i prepped it like it said and it seemed to do something, then i went to #3 cause it says attempt perm root so i clicked that and it seemed to be doing something and then flashed at me and said rooted! and my phone turned white and i had 4 option like bootloader, reboot, reboot botloader, and something else i forgot. I'm not sure what i should do from here so i clicked just bootloader and it took me to a different screen then i just restarted it and i downloaded terminal emulator and typed in su to see if it was rooted and it wasnt. I'm confused once my screen turns white and asks me what to do
By "Supertool", do you mean Bubby's root method?
Idk who its from, but i got it from this website and its called htc supertool and says it works on almost every htc phone
No he mean the HTC supertool from the general android section. Use the Ace hack kit. It is the only proven way that I know of. We have all used it at one time or another and as long as you read the manual you will be fine.
This maybe a little exaggerated, but you may download Ubuntu and run from a USB drive for example and run aahk from there...

It's not recommended to run from a USB drive. Use a live CD instead. (It's in the effen manual for aahk).
You can install the live CD in a usb with unebooting, that's what I mean

lol what are you saying? The Hack Kit is the best way to go. The OP has been instructed to use this tool and if he still runs into a problem, the OP should re-read the the first post in the hack kit thread and the manual to be sure he/she didn't miss a thing. If problems still persist I believe the IRC chatroom is still in service.
I should stop writing short replies, I mean you can install the live CD in the USB with unebooting or other tool, from there use the aahk

[Q] Bricked??

i recently tried to install jellybean but the rom did not work on nexus s, i stupidly removed the only working rom from my 'sd' card and now my phone only boots into a black screen, i have tried to put a known working rom on my phone but every pc i try to connect my phone to says the device has malfunctioned and windows cannot install software. i have tried to use adb but that also cannot find my device. am i looking at getting another nexus with a broken screen and using my working screen to gain a decent phone back or am i missing a vital programme that will fix my utter cockup? thanks in advance
Are you familiar with adb? Because unless you have the right drivers, you phone won't be recognized. Also, usually your computer won't notify you when you're connected and able to use adb, you have to start the interaction through cmd.exe. this being said, try adb again to move a rom or backup into your device.
Also, can you boot into fastboot? If so, is there a warning message or anything?

i am only famililar with adb to the point of rooting, i have tried to download the drivers but only can see .dll files in the driver folders no option to install said drivers. i can get into power and vol up if that is fastboot?? the problem been is i installed a rom which was meant for the nexus s and i didnt read all comments and later found out it does not work with the nexus. i now cannot access the sd storage to put a working rom onto it . when i open cmd and type adb shell it says device not found. brains ready to explode right now. any help on adb is greatly appriciated
Fast boot is when you phone is off, you turn it on by pressing volume up+power at the same time. Let me know if there is a warning text in red at the top.
Do you know how to flash factory images? Because you may be able to do that to get a stock os on your phone. It would wipe everything, however. Flashing a factory image doesn't require you to open SD storage. I'd link you to the thread with the tutorial, but I'm on mobile :/ ill post it if i get a chance, i know its floating around in the nexus s android forums

i can get into fastboot and at the bottom it says

my laptop does not recognise the phone so i dont know how to flash a factory image. this is the cmd sequence i get
adb shell
error device not found
tried mounting sd card and data but no joy
also tried mounting usb storage.
all i get is device has malfunctioned and will not run
tried downloading google usb drivers and samsung drivers all to no avail.
fingers crossed you can tell me something i dont know as i really cant afford to buy a new phone
Well it seems you sdcard isn't dead, which is good! When mine was, fastboot gave me an error.
Now IMO, you should be able to flash a stock recovery image. This will clear everything you have on ur phone, but it should get it back to working condition.
Ill post a tutorial on how to do it tomorrow, that's the soonest i can get on a computer. It is not that hard, and it helps when you're already somewhat familiar with adb. I used to be a noob too, now I'm slightly less noobish!
So as i said, i think i have a solution, ill post how tomorrow, when i have a PC (in on mobile right now).
Cheers, i hope i can fix your phone!

Alright, so this is the guide to install a factory image: http://forum.xda-developers.com/showthread.php?t=1572307
What a factory image will do, is restore your phone completely to a new like state. That being said, you will lose anything you have on the phone (picture, music, etc..). I don't know of any other way to help, so if you're willing to lose everything, but get your phone working, continue reading.
-First, you have to determine what model on Nexus S you have. If you're on AT&T or Rogers, you have an I9020A, and you have to download the "sojua" factory image. If you're on T-mobile, or have the version with an S-LCD display (as opposed to the normal AMOLED), you have to flash the "soju" factory image. If you're not sure what version you have, let me know what carrier you're with.
-Second, download the Factory image corresponding to your phone from the link I posted, as for version, that's up to you, but I recommend 4.1.2 (JB).
-Third, Make sure you have all the right drivers, and the android-sdk installed. You should already have this, since you've use adb before.
-Fourth, follow steps 1,2,3 and 4A in the link I posted above.
Follow these instruction, and if you do not understand them before doing the procedure, just ask a question here! good luck!

still adb cannot find device.......... any links for known drivers for nexus s on win 7 64 bit?
You might need to reinstall the android SDK and drivers, there should be a link in the link i sent you to show how to do that.. If adb still doesn't recognise, your main board might be fried

i wish someone could just see this, pdanet asks me to connect my phone to finnish installing the drivers, problem is the phone is NOT RECOGNISED i know exactly what you are all saying to do but my phone will not connect at all. more than happy to post it to one of you guys on here to fix but like i said ive tried everything and have pulled nearly all my hair out in the process
Samsung repair? I know what you're talking about, it happened to me, I was completely bricked, all I could so was send it to Samsung repair..

Damn, if only you could get it recognized you'd probably be able to flash custom recovery through fastboot and I guess you'd be able to install from sd without data loss.

[Q] Cant reroot my nexus 5 (bootloader already unlocked)

Hey guys,
A few months ago I successfully rooted my Nexus 5 using the first youtube video you see after youtubing "root nexus 5" (sorry, new members cant post links).
unfortunately i had to remove root access for a short period of time. now that i try to reroot the phone using the above method (as well as a few others) It doesnt work.
when I put the phone in fastboot mode it says SECURITY BOOT: enabled and LOCK STATE: unlocked. Im assuming that means the bootloader remains unlocked. when i run the program and my nexus 5 flashes all the magic voodoo rooting screens, the phone boots back up but i still dont have root access.
what in the world can i do here?
You shouldn't be using programs. Just follow the guide we have here, linked in my signature

appreciate the thought but that doesnt really help where im at right now. im probably using the term "programs" incorrectly. i just installed hammerhead and ran it using this n that. Ive taken a look at several guides as well giving me the same operations (download this hammerhead thing. run the thing which then roots the phone with its usb debugging on). I would think that the majority of guides on youtube are derived directly from the guide found on xda anyway (especially the one i used, considering it was a relatively light and easy process).
No most guides use Toolkits. Our guide is proper. We cannot vouch for others.
Our guide involves flashing a recovery and then flashing root from recovery. Do that and let us know where you get stuck, otherwise we can't help
Sent from my Nexus 5 using Tapatalk
Rootsu is correct. If you want things done properly you're best using no shortcuts like Toolkits. Different OSes and drivers and cables may change how the toolkit works.

[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

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
