Help - Phone keeps booting to Bootloader - Nexus One Q&A, Help & Troubleshooting

So..I think this might be a trackball issue and i'll explain everything that is going on.
1) Decided 2 days ago to reboot my phone
2) Phone booted into Bootloader automatically
3) Volume up and down didn't work to select anything and the power button wasn't working either.
4) Rebooted again by pulling battery, loop back to number 2
5) Rebooted via fastboot (fastboot-windows reboot)
6) Success - loaded OS, con - Safe Mode - All buttons work (Volume, Power, trackball is a little wonky)
7) Rebooted phone to see if I could get out of safe mode. No luck
8) Goto number 2
9) Posting on this forum
10) Question - is there a hack out there that I can use to disable the trackball...i think the trackball is what keeps putting me in the bootloader as well as safemode. Returning my phone is not an option for the next few months since i'm now living in the philippines. Any ideas would be greatly appreciated. I honestly think this is a trackball issue so wiping and reflashing the rom just seems pointless at this point. Is there a way to force my Nexus one out of safe mode through a fastboot cmd? Looking for your input.
Thanks for your support here is what i'm running:

[Q] MIUI 2.3.4 for Galaxy S Gone wrong

Hi All - while in the process upgrading from the previous version of MIUI to this latest one, I accidentally selected the 'restart system option after formatting the system, cache and data without flushing the new ROM and now the phone won't boot up. It goes to the main Galaxy S screen followed by Galaxy S Glitch screen then it runs some coding (in seconds so i don't know what is says) and then back to main Galaxy screen in a loop.
What I have tried
> Going to recovery mode with vol up + home + power button (released @ first Samsung Screen) but then it goes back to second Galaxy S Glitch screen in the same loop.
> Going to download mode with vol down + home + power button and it does the same as going into recovery mode.
> Tried to do go into recovery and download mode multiple times using different combinations of vol up, vol down, home and power button without success.
> Read through the threads here but I was not able to find anything with the same or similar problem problem
> I tried to follow the help provided by Thyrador on this forum
http://forum.xda-developers.com/showthread.php?t=1109110 with Odin except using the jig method and no go
> Connecting phone to ODIN keeps on going rebooting in the phone in a loop as well.
I know if I can go into recovery mode I will be able to flush the new ROM but getting there is the problem.
I would appreciate your help with this and hope there is a fixable solution.

I have done that a few times and both CWM and download mode should be there.
Make sure everytime you try the 3 buttons you actually remove the battery before trying.
K.
Edit: the coding you are talking about is CWM trying something and that's shy I think it is still there.
Did you just format system?

Thanks for your response
I actually formatted the system, data and cache without flushing the new ROM.
I tried what you said about removing the battery but that didn't show anything on the screen when I tried the 3 buttons. Is that what you meant?

What I meant was a bit dumb as since you have a bootoop you would have removed the battery anyway each time to try.
I normally flash the same way like you and I always do a factory reset (which formats Data and cache and I do the system manually. Unless soemthing has gone seriously wrong I don't see why you would not be able to get back to recovery?
I have even done it today actually and managed to go back to recovery.
I would say try and boot into download mode. Did you use Download Mode in the past? Are you sure it is there?
I read somewhere else someone saying that it does not always work the first time. Give it a few tries.
Your last option would be the JIG obviously but hopefully you should be able to get it sorted without.
K.
To tell you the truth I always use an app to boot the phone into recovery or download mode however one of my work colleagues has always being able to reboot my phone into any of these modes using the three buttons - not sure how. I will continue to try anyway.
Thanks again for your response and for give me hope that this has happened to you in the past.

[Q] Fastboot not working, no power button, how to flash?

Hello.
I woke up yesterday, dig into my pocket tried to turn it on... battery was dead so I plugged it in, and then ever since, the power button is unresponsive. It showed no previous signs of flakiness. But I've since spent the last 2 days digging and searching for ways to salvage. I see that Cyanogenmod has a nice trackball wake feature that could solve my problem. I download the sdk, and try to unlock the bootloader with fastboot, but fastboot FAILED with status read failed too many links (on windows 7). I tried on a Mac and it also failed for similar reasons. ./fastboot-mac oem unlock
... ERROR: usb_read failed with status e00002ed
FAILED (status read failed (No such file or directory
So from what I've read, pretty much all flashing of roms require either a power button and/or fastboot (because of the radio?). Is there another option I'm missing? I was able to root the phone by downgrading from 2.3.4 to 2.2.1 using the passimg method and using superoneclick. So now I have a rooted froyo phone, with no power button and can't seem to access with fastboot.
Any assistance would be great. I'm just trying to salvage the phone and resurrect it.
Thanks.
Ok, I think I've done something wrong. I used ROM manager to download and install cyanogenmod 7 but now my phone hangs on the X. I let it sit for like 30 mins. Then pulled the battery and booted into recovery mode and reloaded the passimg file from before. It is currently back to froyo. What, if anything can I do? Thanks.
You're never going to be able to use fastboot, because unlocking the bootloader requires you to use the power button to confirm that you wish to unlock...
Make sure you wipe before you flash a new ROM.
Using the ROM manager I selected to wipe everything and then it reboots into the triangle exclamation point. What is the method to flash without fastboot or a power button... it seems even the ROM manager needs the power button. What am missing here?
You need to install a custom recovery. You can do this from ROM Manager - don't use Clockwork 3.x
Thank you so much! I was able to push it through that way. Now that I've got CM7 on it I'm good... but now I'm left wondering if there are better ROMs out there... guess its time to play. Thanks again.
Ok, Now of course... there have been issues. Just getting it up and running had me a bit too excited. Now it seems that the screen is fading in and out... while 'sleeping' and usually when I unlock the screen the power off/airplane mode menu comes up. I 'think' the power button has regained some limited function... and is constantly pressed perhaps. Because now when the screen does remain asleep for a second, I can push the power button and it will wake. But when the phone is on, if I push it, it doesn't go to sleep. I've done some searching but haven't been able to find an app that disables the power button on the N1.
Any thoughts on what I could do, because this is quite annoying. It just flashes off and on and off and on. Thanks again.
The power button is on a separate board connected by a ribbon cable. You could just disconnect the cable?
You could just buy the button with a flex cable, and fix the phone...
Yeah, that too - lol!
Once inside the box, its sometimes difficult to think outside it! xD

[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.
@Dude Random21 and Danger-rat

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.

[SOLVED]Can't boot to bootloader

I finally found solution! Bootloader on my phone isn't nearly same as usual one, no white screen, just a few lines which designate modes. 4 are present:
-normal boot
-fastboot
-recovery
-UART boot
I accessed it by pressing and holding power button and volume up button at the same time during device boot.
I hope someone with a same problem will find this helpful!
I managed to boot to system but I still can't get in bootloader. No combos and neither adb works.
I got my HTC One from second hand several days ago and I instantly noticed that something wasn't right. System was naked, no bloatware, no usual settings, no proper identification so I decided to install custom rom. I tried to boot to bootloader which I wanted to unlock(I guessed it's locked 'cause recovery is stock) with key combos, adb but it simply didn't boot to bootloader nor it rebooted or sometimes it went to factory mode which is on chinese. Again, I tried to find which version of phone I own but I can't figure it out. Moreover, I downloaded and put stock rom on virtual sd card and booted to recovery, opened menu with power button and selected to install package from zip just like it's said in thread but it outputted 'Install /sdcard...' and nothing else for past couple hours. Recovery isn't frozen, It shows\hides menu when power button is pressed. I tried to force shut down it by holding only\in combination with power button\volume buttons but nothing happens. I don't know what else to do...
Any help would be appreciated.
EDIT: It eventually discharged but when I turn it on with charger in it I get blinking white screen on every 3 seconds and when long pressing power button phone just vibrates. In combination with volume down it keeps blinking on every 3 secs and with volume up on every 5 seconds. To me, it looks like it's trying to boot but bootloader can't find anything installed. Computer is recognizing usb device on the moments when I connect it with usb just like when device is rebooting.

You have a fake phone
I agree, you've probably got a counterfeit One, but you can't flash custom roms from stock recovery anyway.
Firstly, thank you for any answer. How do you mean 'fake'?! I got it in original box and IMEI's are same(on box and device) What can I do with it then?
I tried to flash stock rom designed for stock recovery, at least that's how I understood.
MIDN07100 (Europe, a guy from which I got device claimed that it's from England so this should fit)
IMEI:354436053103493(same on device and on box, checked with IMEI checker it appears as valid HTC One device)

[A] Soft bricks, blocked recovery, bootloops - RESCUE TIPS

Ok, so there are a lot of threads about soft bricks and bootloops, I have answered in a lot of threads but it seems it needs separate thread to explain how to "revive" your phone from bootloops and soft bricks.
First of all, I don't guarantee that it will work but mostly this tricks do their job.
Tricks were tested and worked on many phones, but I don't take responsibility for hard bricked phones after performing tricks from this thread.
Sometimes you need to repeat process because everything must be done with perfect timing. Also if one method won't work try another.
1. Prepare your phone to press recovery combination and while plugging phone to USB or charger, hold keys and release when samsung logo appear. Do Factory reset in recovery
2. (the best) turn on phone into download mode and don't accept terms, when phone will reboot quick hold recovery combination and release when samsung logo appear. Do Factory reset in recovery
(3). Emergency download mode (when phone wib but don't turn on screen) - take off battery for few minutes, after that time hold download combination and insert battery, wait few seconds (so normally it would boot and enter dm), accept terms by pressing volume down, connect USB and flash stock Rom
4. usefull tip - Always have backup created in CWM on phone, you never know when it will be needed. What I do is creating backup every week/two weeks, also I have stock backup. I really recomend to create backup before flashing CM while you are on stock (it will guarantee everything will 100% work if something fails), it helped me a lot of times.
(recovery combination - volume up, volume down, power, home)
(download mode - volume down, home, power / accept terms volume down, decline - volume up)
In 1 and 2 "just in case" you can flash stock Rom, when it will start to reboot after Odin finish flashing, take off battery and insert again (to stop boot process) phone should boot into recovery normally but repeat point 2 to be sure.
Also, what is importiant, ALWAYS have turned on debug mode in your usb settings, first thing you should do after flashing CM, turn on debug mode.
===================================================================================================================================================
When you are switching from CM to stock, after flashing stock you will have almost 100% chance that you will have bootloop on samsung logo. You have to factory reset before first boot. So, after flashing stock, when odin will proceed reboot your phone, unplug phone and take off battery (take off battery cover before flashing, but be careful not to drop battery while flashing via odin, it would be really really bad for your phone, hold phone and battery all the time). After inserting battery back and assemble cover, go to recovery and do factory reset.

Thank you for this ! The decline download mode agrements , press recovery combination trick worked , I managed to get to recovery ! I flashed stock rom 3 times and tried repartition with pit ...but this is the only thing that worked ! Thank you
Now I have a Idea about a Un-brick:
1. If you want to return (after a Forget a clean data/cache/dalvik) When You can downgrade with .md5 Stock ROM (or Custom)
2. If Recovery Doesn't works... You can only Download Mode (Volume Down + Home + Power) - Remember it's that's not with SIM/SD Card [Maybe that's optional if it forget but I will be recommend.]
3. Flash to Newest "ClockWorldMod"
4. After Restart - That's must be take off battery and Connect USB Cable to SGMII
5. Let's Turn On Recovery Mode with a "Samsung Logo" Before Input Battery [With a Battery it's doesn't does it Start,on Fortunately...]
6. And... Let's to clean data/cache/dalvik... And that's All of "Open source Unbrick"
What Did a get:
+ Downgrade ROM without a Additonal Box (Because that's Open source with a Easy-Root and Not Close-Source as a Self of Old Sony Ericsson Tuning - But I Like a Old Sony Ericsson's Too ... And "Sony" looks from a 2007 about a Modifications and Sony is not a blocked for Android - Fortunately... And for a Today Some users remembers about a Big Seasons Tunings from K310i or K550i [I had a Two phones... That's nice what I discovered about a ROM's Modifications... And Let's praise for Sony that's Not blocked for Androids... Thank you,Sony. ]
+ That's can be again to Upgrade eg. Cyanogenmod
And... A knowledge... Hope that's share a help.
might want to consider adding this
Hi OP, you might want to add this to your thread..
so, early this week, i faced a bad bootloop situation after the software update.. Even with a normal boot (no vol+,home button and power button pressing), my phone will still be stucked at CWM recovery..
Note that my phone was working fine, only the software update caused my phone to stuck in the CWM bootloop..
So, what i did was, i updated my CWM 4.0.8.2 [ my bad, cause when i rooting my phone initially last few weeks, and i've been reading outdated threads].. So, i updated my CWM 4.0.8.2 to CWM 6.x through CWM recovery..
Then, after it rebooted, i go to download mode, connect my phone through ODIN and flashed stock rom.
Now, it is working fine like new..
