[Q] Unlock bootloader on 4.1.1

Hi I'm somewhat an android noob. I owned a moto droid back a few years then I had an iPhone and forgot a lot about android and a lot has changed since then. I now have the galaxy s3 and I love it. I have it rooted and have clockwork recovery installed. My question is that to install custom roms I know you need to have an unlocked bootloader. How do I unlock it on 4.1.1? It seems that most information I find gives details for earlier versions of android then what I have and I don't want to do something incorrectly and mess up my phone. Any help would be great. Thanks.
Edit: Nvm I found a zip to flash to unlock the bootloader. Thread can be deleted.

[Q] Trouble unlocking bootloader HTC ONE X AT&T

Dear XDA experts,
I'm trying to unlock the bootloader on my HTC one X phone for AT&T. My reason for doing this is i am no longer using AT&T so i unlocked the phone but i would also like to be able to use the wifi hotspot function which AT&T has blocked.
I followed this thread : http://forum.xda-developers.com/showthread.php?t=1671396 to accomplish the unlock but I'm getting this error when typing "su" in the adb shell command: /system/bin/sh: su: not found
127|[email protected]:/ $
I rooted the phone (AT&T HTC ONE X) using this technique : http://www.androidauthority.com/att-one-x-root-87398/
I'm a little new to all this so I would really appreciate any input.
Thanks a lot!

The Issue might be caused by your Firmware I Personally Recommend using Hasoon2000's AIO Toolkit which can be located @ http://forum.xda-developers.com/showthread.php?t=1952426 ive tried it on 5 of my devices all One X and works without an issue. If you run into errors feel free to contact me

I'm really grateful for your reply, thanks for taking the time to answer me.
I was about to download the toolkit you mentioned but i noticed it says v2.0 and I'm running 2.2 is that still going to work ?
Also i before i read your post i had tried this technique :http://www.bestandroidblog.com/root...phone-on-2-20-firmware-with-x-factor-exploit/ which actually almost worked. What i mean is i was able to get the unlock token from http://htcdev.com/ but when i try to flash it to the device it just says "waiting for device" and i don't get the message on my phone asking if i would like to proceed with the unlocking of the bootloader.
C:\Android>fastboot flash unlocktoken Unlock_code.bin
< waiting for device >
The phone is on charge only mode and has usb debugging enabled.
Please help.

Yes all the Version Means is it's Version 2.0 for the ToolKit, You probably have the 2.20 Firmware on Your phone... any way yes the ToolKit Will work, as a Troubleshooting step, make sure that you have the latest fastboot Drivers for HTC, and those can be found @ http://downloads.unrevoked.com/HTCDriver3.0.0.007.exe also check your device manager and make sure that your PC is recognizing the Device, it should say Android Phone --> My HTC, or something similar.

[Q] How to unlock/root a Nexus d720?

Thread title says it all. This is for a friend that has never rooted or unlocked any device before. I'm going to help him. Anyway, I've searched for over an hour and can't find and d720 info. It's one thing to brick your own device and another to brick your friends.........

Nexus S 4G (sojus/crespo4g/d720) is not SIM locked to a single carrier. If your friend is looking to switch carrier, simply switch SIM (provided frequency is compatible).
Try searching oem unlock and rooting instructions for Nexus S 4G.
eg. [GUIDE] [NS4G] Simple Root/Unroot For latest recovery and superuser see below.
Install Android SDK Tools and when SDK Manager runs, install Android SDK Platform Tools and Google USB Driver packages for fastboot/adb commands.
fastboot oem unlock --- will erase all data
fastboot flash recovery recovery-clockwork-5.0.2.0-crespo4g.img
flash via CWM Superuser-3.2-arm-signed.zip. Other versions or superSU can be found here.

Ok so I finally got to look over his phone. No SIM card and no SD card slot - weird. I'm at a loss now. His upgrade hits in June and he's going to get a new phone and is not too worried about rooting. He's just wanting to learn and I was going to help him out. Any further help is apprciated.

It's not weird. It's a cdma phone so there's no sim card and nexus doesn't have true sd.

[Q] "New" phone from ebay (villec2) that will not update. Unlocked/Rooted?

Hi
This is my first post here, and I'm hoping somebody could help me with some questions I have.
I have recently bought a "new" HTC one s on ebay, which may seem to have been a bad idea. I have later discovered that it is not a z520e (snapdragon s4), but the cheaper z560e (snapdragon s3) version, or villec2 running android 4.0.3.
Anyway, I have tried to upgrade the phone to the latest android version, using the built in phone function. However, this did not work and I got an error message telling: "We have determined that your phone may be running modified version of its system software...". In other words, I have the feeling that the phone is tampered with. Maybe the seller have unlocked in a way that makes it impossible to upgrade. Is there anything I can do to check this? And is there anything i can do to upgrade to android 4.1.1. ? I have tried a factory restore (phone function) with no luck. Or is the update only available to Asia?
Any information is very appreciated. I would like to know what the seller have done with this phone, information which I can use against the seller. Thanks!

When the phone is off, press and hold volume down then press power button (don't hold).
This will let you enter bootloader.
Top of the screen if it says unlocked, that is why you cannot update.
I'm guessing you do not know about fastboot commands/ adb commands and are not interested in learning to root and load custom ROMs to your phone.
But if it is unlocked and you want to relock it you just need to type in a command prompt: fastboot oem lock
that is assuming that the stock recovery hasn't been changed. (which isn't hard to flash)
In this guide you would want to download that fastboot.rar file
http://forum.xda-developers.com/showthread.php?t=2175411

As this is a question, I've moved this thread to the Q&A, Help & Troubleshooting section.
In future, please remember to ask any questions in this section rather than in General.
Thanks

First of all, sorry for the posting in the wrong category.
You have right that i have no experience rooting android phones. However, i managed to jailbrake an iPhone 1st gen in the old days.. Anyway, my main concern is to try to find out what this phone is running, and if I should send it back or not. I paid 260 usd, so I would like the phone to be ok/not too much tampered version.
I got into fastboot / Hboot, and it says unlocked. What does unlocked actually means? I also got some red text when i started the phone afterwords telling that it was some non officially software that were not allowed to be distributet (went a bit fast).
I guess this is the reason why I cant update. Is there some more information I can take out of this Hboot? (I tried to find a hboot guide.) Any ideas why the seller sold me an unlocked phone? And is there something i should make sure of before I decide to keep the phone? I might send it back if there is some tampered things here.
Thanks again for you feedback!

HTC allows to unlock the bootloader from their website. You are sent an unlock bin code. Unlocked means you can root the phone, you can put on a custom recovery to make backups of your phone and put custom ROMs on it.
If yours said unlocked, and right below that if it did not say tampered, then i believe you still have the stock recovery.
you just need to download fastboot files to your pc then you can lock your bootloader.
you go back into bootloader and plug your phone into computer (phone will change from fastboot to fastboot usb)
from your fastboot folder you hold down shift and right click the mouse, choose the option to open a command prompt.
from there you just type
fastboot oem lock

Thanks for the reply!
Yes, i cannot see any "tampered" below the *** unlcoked *** line in HBOOT.
I tried the recovery in the HBOOT but got a red triangle. I guess i need to to this from an PC (I have macbook at home, or do I need the Andorid SDK on my computer maye..), and download the right android image etc. I also guess the factory reset will not help me either (probably the same function I can choose from the settings menu in android.).
Now my question is if I should try to change it to a z520e. I guess i will get some more battery life with the snapdragon s4. But not sure how much, and if its worth the hassles with return shipping etc.
Anyways, thank you very much for the information!

[Q] Nexus 5 fully wiped (system, data...), bootloader Locked

Dear all,
I am new on Android, the Nexus 5 is my first android device. I freshly come from a 5 years old iPhone 3G.
2 Weeks ago I unlocked the bootloader of my device and rooted it following the tutorials provided by the XDA community without any problem.
Today, I saw that the OTA to upgrade from the Android version 4.4 to the version 4.4.2 was available directly from the device.
Since I did not want this update to be a problem with my rooted device, I downloaded the following apps: BootUnlocker for Nexus Devices and OTA RootKeeper (I do realize using RootKeeper was stupid since anyway the last update was released on July 25, 3 months before KitKat...). But anyway, this is what I did. I used those apps to Lock my Bootloader and unRoot my phone, thinking that this will reduce the chances of potential conflict with the OTA update.
Afterward, I downloaded and tried to instal the OTA directly from the Nexus 5. It ends up that I got stuck on the recovery menu. It was then impossible to get back on android and I did not know what to do.
This is where I did something totally crazy. Usually I spend time reading tutorials and finding information before doing anything that I do not fully understand. But at this stage I simply thought that the update could not properly instal due to the root. So I went on Advanced Wipe, I ticked all the options (data, system, Cash, Dalvik... all of them), and wiped the device.
As a result, my Nexus 5 has currently a Locked Bootloader and no OS installed. This means that I cannot activate the developer menu (no OS) to tick the option USB debugging. Thus, I cannot unlock my bootloader and in consequence I cannot instal the factory image and get back to stock.
Please, If you can give me some advice, explain me how can I unlock the bootloader in these conditions. Let me know... I really don't know what to do now.
PS: sorry my english is not perfect but I do hope you clearly understand my problem.

You've got it all wrong. You do not need USB debugging to unlock bootloader. to unlock bootloader you must use FASTBOOT commands, which means you MUST be in the bootloader itself. USB debugging ONLY works in android.

Dear RootSU,
So this means that I am not stuck at all and that I am simply limited by my current knowledge about android?
If this is the case, then "alleluia"! I will document myself to be able to fix this thing.

Pretty much
You should be able to unlock the bootloader as you did before.

Boot phone to fastboot mode, download fastboot and adb kit to you computer... it can be found here on forums easy, and in comand line to unlock bootloader you need type "fastboot oem unlock".
More complete guide you can find here http://forum.xda-developers.com/showthread.php?t=2507905 =)

It's ok now!
As you said, I could unlock the Bootloader the same way I did before. Then I install the factory image 4.4.2, which I rooted directly.
Thanks a lot RootSu, you've shown me my mistakes and put me on the way to fix my problem.
Thanks also for your concern Biggreen. =)
Problem solved!

Dear RootSU,
One more question, could you explain me why I got stuck into the recovery menu when I first tried to update via the OTA? Will I get the same kind of problem when I'll update with the v4.4.3 in the future?
Thanks

I am not sure on the extact reason. OTA itself will not install with a custom recovery. You have to download the OTA and boot to recovery then manually flash.
There is a good "OTA Helpdesk" sticky thread in general you should read as theres lots of advice there

hi there...i've got the same problem... i wiped everythink and now i'm not able to switch on my phone....i just want to get out of this somehow...i'm very much new to this and i just want to get my stock android back that's it...somebody please help....

Do you see the battery icon when you connect the phone to a charger? Does the LED turn red when you connect the phone to a charger? Maybe leave the phone connected for a couple of hours and then try to power on?
