Hi,
I'm new to Android. I'm checking out the CyanogenMod guide and it says:
If the Bootloader on the Nexus S has already been unlocked, you may skip this section.
.. how do I check if my nexus comes unlocked or not?
Thanks
Power off the phone hold and continue to hold the volume up button and press the power button. Use the volume keys to toggle down till recovery lights green. Press power buttom. If you see the custom recovery titled: Clockworkmod then it has been unlocked. Or the other method to bypass this has been done.
Or more simply if you are the first owner of the device and are new to android you don't have a unlocked bootloader because you have not done the precess needed to root the device.

Ummm your bootloader can be unlocked without changing recovery.
Just turn the phone off. Hold volume up and power, this will get you into bootloader mode.
Look for lock state. It'll say either unlocked or locked.
If its unlocked, you'll see a lock under Google upon turning the phone on

I suppose someone should add that unlocking the bootloader while simple enough in comparison to other devices, will erase the internal SD of the phone so make a backup if you have anything you don't want to lose
It is possible to root the nexus s without unlocking the bootloader thus not losing data. I did the oem unlock on one device and the non oem unlock on another. There is a thread for it in the sticky.

okay so i found backdoor to flash the ROM on your nexus one phone "that probably wont void your warranty[i haven't tried it yet]"
turn off your device>
when fully powered off
first press and hold the trackball then holding down the power button
now you should see a white screen with droids on skateboards
now using the volume up/down buttons scroll the blue stripe to the spot that says "BOOTLOADER" and press the power button
next (using power up/down buttons) scroll to "RECOVERY" (it will reboot .....be paitiant)
when you see the android (robot) with the triangle warning sign
simultaneously press the power button and both volume up and down buttons
now you should see the "android system recovery" (with blue text)
you should see the following
-reboot system now
-apply sdcard:update.zip
-wipe data/factory reset
-wipe cache partition(this is good if your phone wont connect to data or is unresponsive)
-apply sdcard:update.zip is the one you want to use
but make sure to rename the new custom ROM file update.zip
please tell me if this truly works without giving you the "unlock bootloader screen that says 'unlocking the bootloader will void your warranty"
Most interested in this, don't have mine yet though.....

I doubt this will work since it never worked with older android phones like the g1/mt3g.
There is no way you can void your warranty. If something goes wrong just flash the stock nexus one rom without root access and lock the boot loader. They will never know.

There is a stock Nexus One ROM somewhere in the N1 section. Do a complete wipe and flash that. Then go into fastboot, flash the stock N1 recovery (somewhere in the N1 section) and then lock the bootloader. I think the code is something like fastboot oem lock bootloader.
what a great idea...
except the bootloader will not accept the lock command....
as to my knowledge, there is no way to go back, when you unlocked the bootloader, it stays that way...
but please correct me if I am wrong..
I just got the google nexus s 4g phone and im trying to root it but i cant get into bootloader mode? Ive tried both volume up and power and volume down and power and it just boots to main screen. Is there something i have to do first to get into bootloader mode that i missed or something?
Nop, just press volume up, and while keeping it pressed hit power.
To add to that, make sure you keep them held down because even letting off slightly early just brings up the Google screen. At least in my case.
Not to mention the phone needs to previously be off
Since you're going to be unlocking it you're going to be using fastboot once you get there. Boot the phone up normally and make sure usb debugging is on if it isnt. adb reboot bootloader
Hello all,
Slight problem...i just rooted my phone (ATT) did all that good stuff...and then when and flashed cleanROM's rom....cleared all the cashe etc....and now it seems that all my phone does it show the HTC start up page and go black. if i hold the power button, the lights on the bottom flashes about 7-8 times and then goes to the HTC start up page again. can someone help me get my phone working again?

or even better still, s-off then you won't need to worry about flashing boot.img ever again!
i can't get the phone into the bootloader or recovery. Is there another way i can get into that?

To get into bootloader hold vol- while holding the power button. Don't let go until it reboots. It will now be in bootloader

You need to let go of power, but keep holding vol down. If you don't let go of power, nothing will happen (except the phone shutting off).
The most surefire way (works in just about any situation) is to hold power and volume down. Don't let go of volume down until I say so later. The capacitive buttons will flash after about 5 seconds. Then the buttons will stop flashing, the screen will turn off (if it was on). After that, release the power button, but keep holding volume down until the white bootloader screen shows up.
If the screen turns on at all, the phone will always be able to go to bootloader. Failure to get into bootloader is almost always a matter of the user not performing the button sequence properly, rather than an issue with the phone.
I have unlocked my bootloader through the Motorola website but when I boot into the bootloader now, the message that says the bootloader is unlocked pops up and turns my phone on.. So I can't pick the recovery option to install the supersu file.

If you google "rooting the motorola photon q" the top result is a very good guide.
If you follow the instructions in there, it's pretty straight forward.
You should still be able to boot into recovery by pressing and holding volume up and power button to power the device on, and then pressing volume up and down simultaneously when the dead android displays.
You can also still use any of the many rooting kits people have put out there, or root via adb with USB debugging enabled.

I have an HTC Desire S with a broken power button. I manage to power on the device by using quick battery in-out trick, and unlock screen with an unlock app. I want to root the device and install custom rom.
The problem is that i cant select items on the Bootloader menu since the power button doesnt work. Is there some way to select items without the power button?

How is the power button broken? You might be able to fix it if you can take the device apart which is quite easy, I've done it. However, that would have to be a risk you're willing to take. I'm not sure if you can navigate the bootloader without a functioning power button. But I know you can access fastboot from the command line. Is your device S-OFF? Is the bootloader unlocked?

The power button became lesser and lesser responsive over time. i had to press multiple times before the screen would unlock. Eventually it just stopped working. I have taken the device apart once, with hopes of fixing the power button, but it seems that the power button is a tiny button surface mount directly to the main board. I cleaned eveything out, but no luck.
The device is S-ON. I havnt done anything other than installing the Official ICS upgrade. How did you fix your power button?

I should've explained why I took mine apart, I took mine apart in order to mod the unibody thing. I've seen websites that sell replacement parts so if you feel confident about repairing it yourself then you could always consider that.
Back to your initial question. You will be on the most recent HBOOT due to being on the ICS upgrade. Follow this guide by skanob in order to downgrade your HBOOT. Then use Revolutionary to S-OFF and install a custom recovery to your device. Then you should update your HBOOT to 7.00.1002 so that you have no difficulties with any custom ROMs.
Remember to read all the guides in full and make sure that you know what you are doing and that you are prepared before you start doing anything to your device. And make sure you are willing to risk damaging your device. Every device is different, personally my DS had no issues with any of these things I used as you can see in my sig.
Good luck.

This is the procedure that i am following. Step 1 itself is to unlock bootloader using htcdev.com/bootloader . This procedure requires me to select HBoot from the bootloader menu, which i cannot, since the power button is broken.

Unlocking the bootloader doesn't require you to select anything. The guide tells you to type some code into a command line. Your PC will do everything for you. To get in to the bootloader all you do is connect your phone to the PC, open a cmd box and type:
fastboot reboot-bootloader

It will then turn off your phone and boot into fastboot.

I have done this. But im now stuck at the final step, which is a yes/no confirmation prompt on the phone, where i have to press power button to confirm.

Usually the yes/no prompt is selected by the volume up/down buttons.
