please help me un-brick my phone

ekh... bought a nexus one off craigslist. it was already rooted. i used it for a day and then decided i didnt want to keep it, so i decided to do a hard reset. it's now stuck on the screen with the four different colors (nexus symbol) and the unlocked lock on the bottom. i've done the clear storage by holding the volume down (or trackball) and pressing power. i've tried to go through all those settings and cleared everything, but it still wont load..
any ideas? do i need to re-flash the original rom? can i flash a rom if it doesnt boot up? please help, as this is my first android phone and i've had it all of 24 hrs.. thanks
omar

Omar,
Please read the second sticky post in the forum "[ROM] Original Shipping - Tutorial" This has all the files and will tell you the steps to return your phone to the original shipping rom.
You can skip to step 5 once you download the necessary files. To get into fastboot mode on the phone do the following:
1. Power off the phone
2. Hold down the volume down key and press the power button (continuing to hold the volume down key)
3. Release both and it should boot into a white screen with the top, highlighted, option being fastboot
4. Press the power button to enter into fastboot mode. The screen should say fastboot-usb in red
Once you see fastboot usb you can begin to erase and flash the roms per the instructions.
FYI: The fact that your phone is booting to the four colored X logo means that your phone is not bricked. It is simply in some sort of boot loop. A bricked phone will show nothing on the screen and will not connect to the computer in any way shape or form.

if anyone can help me via AIM i would really appreciate it. i think i'm just about there, just need a little more info

i'm trying to figure out this fastboot thing.. i got the USB thing to work, so now my computer detects the phone. i downloaded fastboot but it keeps giving me some error message that it cant find some file... any ideas from there? thanks
omar

ok.. found and downloaded the sdk, and now when i open fastboot, it just closes right away.. wtf am i doing wrong?

You are running fastboot from a command prompt right?
To open a command prompt type "cmd" into run.

Posting a thread in the right forum might get you some help. =]

Hope you have a custom recovery (most likely). Hold volume down and push the power button. Then on the white screen, press volume down once and select Recovery by pressing Power. Hopefully, you'll have Amon Ra's recovery. If so, then you will be sent into this recovery screen where you can turn on USB mode which will allow you to connect to your computer so you can download a ROM onto your SD Card. Do that.
Then you disconnect...wipe everything under the 'Wipe' settings...then Flash the new ROM. You should be good to go from there!

[Q] Is there a way to boot from power off directly to Clockworkmod?

So my power button on my Nexus One works 1 out of every 1000 tries. Which makes getting a boot loop and having to go to the white hboot screen a royal PITA.
I don't need or want the white hboot screen. I would LOVE to be able to hold down the trackball and pop the battery in and out and have it just power on into clockworkmod.
Is there a way to do this? Thanks in advance!

Unfortunately I don't think there is a way. There are certain buttons you have to push in order to get to certain areas of the unit. From a powered on state, of course there is the use of quick boot or some variation. But from a powered off state, you must have a functioning power button to be able to navigate through the HBOOT section. It would be great to be able to remap the hardware function buttons to allow the vol-d or vol-u buttons to act as navigation buttons in certain cases, but I think that is nearly impossible.

You can't go directly to recovery but you can go to the bootloader. From there you should be able to follow this guide to skip the recovery altogether. This should enable you to be able to flash your individual files created from a Nandroid backup and then reboot into it. Alternatively you can use the fastboot command:
Fastboot boot recovery.img (Where recovery.img is a copy of Clockwork mod recovery in your /tools folder. However do remember this is a one time boot, therefore you'll need to do this following any bootloop).

Thanks for the reply. I'm thinking the trackball is the perfect candidate seems how it is totally useless in hboot. Sometimes I push it just hoping my prayers have been answered but to no avail.
I am not a programmer only an end user but I think if its possible a few options would be to remap the power button on hboot as you mentioned or to make an option on ROM's where a person could choose to boot directly to clockwork.
Although maybe this would be an option for clockworkmod itself.
Anyway someday someone will figure it out. I just hope that day comes before my power button stops working all-together.
The strangest part is that the power button seems to only have this problem in hboot. If I want to use it to turn off the screen or turn it on again its fine ... But my trackball can do the same ... To sum up ... My trackball only acts like a power button when I don't need it to. The irony.

Thanks for the link. I will have a look and see how it works. ^^

At any point that the device is running, you can issue the adb reboot recovery command via a USB connection to reboot directly into recovery without having to press any buttons on the device. You can do this even while the device is bootlooping (as long as it has gotten beyond the static X image).

In rom manger it has the option to boot into recovery.
Quickboot does the same. Elegos rom updater does it.

[Q] What is the Nexus one power button fail rate?

Hi everyone!
I just purchased a slightly used N1 for my dad for fathers day, and the guy was telling me about how N1s have a problem with their power button. He told me it hasn't happened at all with the phone I purchased, but I wanted to ask XDA..
"Do you have a nexus one with a failing power button? & how long have you had the nexus one?"

18 months and no failure. A free app called Quickboot in the market allows you to power down with a soft button, lengthening the click-life.

Ya I use trackball wake, widget locker and quickboot so I never have to touch my power button except to turn it on from power off or to select in bootloader. The thing is is that nexus one power buttons fail after a while but it depends how much you press it if it's once every 5 minutes ya it'll die faster you can't know if it will die soon there is not really an average dying rate.
BTW: I've had mine 10 months

Power Button failure
I am desperate about my power button status, is completely out of order. I am on latest nightlies but due to FC of launcher, i had to power off my n1. Because of my power button I can not restart or access recovery mode, now it is in bootloop.
Is there any solution???

Is your bootloader unlocked??
If yes then try fastboot flashing if not then do passimg instructions are in the wiki (under unroot/restore) http://forum.xda-developers.com/wiki/index.php?title=Nexus_One/Guides_%26_Tutorials#Unroot_.2F_Restore_your_Nexus

Thank you Dude Random 21,
Yes, my N1 is already rooted, bootloader unlocked, however s-on not s-off. I dont quite understand why is always s-off for more than a year, but i can do everything as rooted device. I read somewhere that my N1 is not completely unlocked, this may be other story
In my situation now the power button do not properly operate as required, so I cannot shut down, ie power down my phone, for recovery option.
Help!!!

You can power down just to turn it on you'll need to plug in your charger (to your computer if you'll be flastboot flashing anyway) and then remove your battery and reinsert it (while holding trackball so you boot into fastboot) you may have to try it multiple times to get it to work.

my power button works fine after 15 months, but that is because i purposely use track ball wake and rarely ever touch the power button. and i use quickboot app as well. i just dont feel like even dealing with the possibility.
so really just root, install cyan 7 or some other ROM with trackball wake, and save the hassle.

18 months, and I use it constantly. I've installed Quickboot, but never use it. I've enabled trackball wake, but never use it...
I'm prepared for when it dies - which will probably be later this evening, now that I've said this...

My power button died after 3 months of use... I'm currently using "anyunlock".

15 months and no issues whatsoever.
P.S. I have never used trackball wake...

No problem here, but I have been careful. I normally use "Power Off and Lock" to turn it off and Trackball to wake. Owned just over a year at this point.
I worry about the trackball wearing out, but I figure if it does it won't kill me, as I don't really use it for much anything else. Love my RGB notification disco ball though, I WILL miss that, even if I don't physically use the trackball itself.

I got to white screen with 3 robotic skaters, ie screen with options: fastboot, recovery, clear storage, and simlock. As I said before, my power button does not work any more, so that I can not push pwr botton for activating recovery mode.
I tried other option using method of recovery image at http://forum.xda-developers.com/wiki/index.php?title=Nexus_One/Recovery_Images. After typing the cmd "fastboot flash recovery recovery.img" the notification is " waiting for device". I think adb cannot see/ regconize my n1, so that I cannot enter recovery mode.
Please enlighten me.

To use fastboot, your bootloader needs to be unlocked and the phone needs to be at the fastboot screen (hold trackball while powering up - looks like the same white 3 android screen, but the menu is slightly different)
If your bootloader isn't already unlocked you may be out of luck (you need to use the power button as part of the unlocking process).
You can use adb to boot into recovery, but you need to be in either recovery (pointless), or booted normally to use adb (won't work from hboot).

I started having problems 5 months after purchase and Videotron replaced it. My wife's N1 just started playing games, also after 5 months.

Ok, I got to the fastboot screen with menu option: fastboot USB..., bootloader, reboot, rebootbootloader, and power down. So 2 question:
In my case, my bootloader is considered as unlock??? If it is unlock how can proceed further ?????, because for selection one of options my pwr button does not work.
With ADB method: this method does not required using the pwr button: I tried as instructions
For unlocked bootloader - using fastboot
The following won't work unless your bootloader is unlocked.
1. Download Amon_RA's Recovery from one of the versions above.
2. Rename Amon_Ra's Recovery Image to simply recovery.img.
3. Download this file - Stock Recovery Remover - and copy it to the root of SDcard.
4. Toggle on USB Debugging (Settings » Applications » Development). Power off the Nexus One.
5. Boot into bootloader mode. (Hold volume down & power button until you see white screen with skateboarding androids)
6. Connect the Nexus One to the computer.
7. On the computer... Open a command prompt/terminal & navigate to the Android SDK Tools folder.
8. Type in the following commands (assuming recovery.img is in the current directory):
fastboot flash recovery recovery.img
fastboot reboot recovery
Click to expand...
Click to collapse
The result is the notifications:" wait for device" and i waited for hours...
In both cases, I cant go further, any way out???

If your phone has the padlock on the static x screen it is unlocked. It also tells you in fastboot if its locked.
Anyways as I think danger stated you need to use fastboot commands when the phone is in fastboot mode connected to the PC etc. It is a not a adb command. Its fastboot devices...etc
I'm the end you will issue the fastboot flash recovery command. Then fastboot boot recovery....
If you're unlocked your fine. You don't need power button. If you're locked you're ****ed
Sent from my Nexus One using XDA App

Yes, I confirm that there is a padlock, and I understand that my N1 is unlock.
I redid cmd: fastboot flash recovery recovery.img and fastboot reboot recovery
But nothing happen. It is my N1 bricked???
My last hope is to replace Power Button.
Any suggestion???

First, make sure your phone is connected by typing:
fastboot devices
If that works, then try flashing the recovery. Post any error messages, rather than saying "it didn't work"...

Using Nexus One from April 2010 - power button working fine. Bought Nexus One directly on google site.

Vol Up key broken?

So, my volume up key stoped working from one day to the next. Didn't slam the phone on the floor or anything, it just stoped working. I already tried it on recovery mode, no luck so i'm asuming it's not software related.
Anyone faced this issue at some point? I did the eb40 battery mod a month ago, didn't notice anything unusual since then.
Thanks guys for any help.

Anyone?
I'm worried i might need to enter recovery or bootloader using keys instead of software reboot at some point, and won't be able to since my keys don't work.

I mean you could open the phone and check the connection for the button and the contacts. Does it feel loose? Maybe the button is upside down ( which shouldn't matter but you never know). Get back to us!

The touch recovery does not require the use of volume or power button. Same with Touch CWM.

Oh. Well of course you don't need the volume key to navigate the menu in a touch recovery. That's not the problem. The problem is getting *into* recovery without the volume up key. The only way to do so is if you have a functioning ROM, so if you're in a bootloop, you have to FXZ back to stock from fastboot, reroot, and install a reboot to recovery app. Then commence doing whatever it was you needed to do in recovery (assuming flashing a custom rom again and hope you don't get a bootloop)

I understand now. Yes, it's tough to access fastboot or recovery mode without volume keys working.

Not at all there are ways to get around this. Install xposed framework with an advance power option and install it. Or go to play store and look for an app name i believe quick reboot

Indeed. I've wasted several development hours just getting back to a workable system when I end up with a bootloop. Makes testing very frustrating.Volume down key still works (it seems people only ever have problems with the volume up button) so can still get into fastboot. It would all be good if the "fastboot reboot recovery" command worked on this phone, but it's blocked.
EDIT: @Technofreak, once again that won't work if you're in a bootloop.

Yes, and fastboot only works while in download mode, which you can't access while on a bootloop.
mmm... is there any way to make the device boot into download mode by default? That would be maximum safety.
Btw, did your vol up key broke by itself? did you do the battery mod? Thanks for your input.

You mean download mode as in the menu where you can choose recovery or fastboot? You can't get to that without the volume up button at all. You should be able to still enter fastboot, even from a bootloop. Just hold down the power and vol down button until it vibrates, then let go. Then hit power button once more, and you should be in download mode. But that still won't get you into recovery, so you still have to FXZ back to stock from there and redo everything. There IS a way (sort of) to get it to boot to fastboot every time. Just flash an FXZ and unplug it while it's flashing system.img. Then manually flash a system.img. That should trigger the sticky bits deal where it boots into fastboot every time... but I really don't know what that will accomplish, because every time you reboot your phone you'll have to plug it into a computer and use "fastboot reboot." There isn't a reboot to recovery command in fastboot, and there is no option within fastboot itself to reboot, so you'd have to plug it into the computer and use fastboot reboot.
I wish there was a software option to always ALWAYS boot into recovery from a cold boot. That way you could always get back to recovery no matter what. FXZ is surely a last resort, but you can always restore a backup from recovery.
Yes, I have an EB40 battery mod. But the volume button didn't stop working until a couple of months after doing that. It was seemingly random. Just stopped working one day. I can't way whether it's related or not.

What about fastboot update? isn't that suposed to flash zip files, as in cm zips?
EDIT: Been trying the vol down + power for a while, it behaves as normal power button, can't get to bootloader.

I have never been able to get fastboot update to work. I believe it is restricted on this phone just like fastboot reboot recovery is. Don't quote me on that as I've never seen anyone outright say that is the case, it just has never worked for me.
If it makes you feel better,don't bother trying to get the scews out. I have taken mine all the way down to the motherboard to see if there was anything obviously wrong with the volume button. Mine seems to have nothing physically wrong with it. The button (the bare button on the mobo, not the plastic piece) pushes well and even gives a nice tactile click when you push it down with the tip of a screwdriver or soemthing pointy. Hell, I've even booted it up with the case off, bare motherboard, while holding down the button with said screwdriver and it still won't work. It's got to be something like a trace burned or cracked on the motherboard, but with all the componants and shields around it I can't tell. It looks normal, and no different than the volume down button.
That sucks that you can't use the vol down and power button to get to fastboot. I just tried it myself to make sure I said it right and it worked fine. Maybe your volume down button doesnt work either??? You have to be very VERY careful if you cant get into fastboot. Don't get into a bootloop, because I don't know if there is any other way to recover at all. The only way I would know would be to short the circuit on the mobo to force the mobo to recognize a volume button press, and nobody wants to mess with that crap. Don't do any mods that are too exotic lol.

Vol down key is ok. Do you press both buttons while phone is off? For how long? This is weird.

Well, I believe the correct way to do it is to hold all three buttons down at one time, but for me just holding down the power and volume down button works. If the phone is on, just hold those two buttons down until it vibrates a couple times. At that point let go of the power button. Then press the power button again, and it should boot into fastboot mode.
If the phone is off, I would assume just hold down the power button and volume down buttons. Then let go of the power button while still holding down the volume button and it should boot to fastboot mode.

Good good. That will at least allow you to FXZ if all else fails. Just don't flash anything unless you have the time to FXZ back and do the whole process over, because in the event of a bootloop, AFAIK that is your only choice.

But we can always go to the recovery mode using the command prompt.
Connect the mobile to computer and use adb fastboot commands.

Once again, fastboot reboot recovery does not work on the Atrix HD. Let me qualify that, because there may be some people that it does work for, but the majority of us, the command is locked. In most cases, that is an invalid point, because we cannot get to recovery using fastboot.

[SOLVED][Help] Installing stock recovery causing problems

Hi,
I'm very new to rooting and such and only followed guides a read forum posts to get to where I am now.
My phone is rooted with stock ROM and SU, the bootloader is unlocked but no S-OFF (don't think it's possible on the mini 2 yet anyway). The new OTA update last night installed when I got home and charged my phone, then the phone just shut off and every time I tried to boot it would go straight into TWRP without showing splash screen or bootloader (even when holding power and the volume down button). When it's in this state the touch screen doesn't work and the power button only locks the phone. Holding power + vol down in this state doesn't do anything.
I have to let the power drain completely to get the phone to boot back up but it immediately boots back into recovery and then I can use ADB to force the bootloader to appear, but when I flashed the stock recovery that I found in these boards, it messes up the screen and all it shows is static with some artifacts. I have to let the power drain again to get back into the bootloader, and from the bootloader I can get the android OS to boot but I'd like to fix this completely.
I guess I should also mention that even after flashing the stock recovery the phone will still boot back into TWRP after I let the power drain so I think that means that the stock recovery isn't taking?

The twrp problem you mentioned is known, hope it'll be fixed soon. Are you sure you typed the right command to flash stock recovery? Fastboot flash recovery recovery.img?
If you get stuck, the combination is power button and volume up, not volume down...

Unfortunately I was using the wrong ADB command, I was typing "fastboot boot recovery.img". This seems to have fixed the problem so far but I have yet to try rewriting TWRP back to the phone and I probably won't until theres a fix or unless I need to.

I had the same problem. It happens when I reboot with my phone when charging.
You can reboot your phone by holding vol up+power button.
