Nexus One stuck in bootloader

Pardon for the long post but my Nexus One has been out of comission for a few days now so I'll list everything I've tried to make it work in an attempt someone might be able to help me!
Okay, here goes.
A couple days ago I removed the battery on my phone to install an invisible shield. Prior to that I had owned the Nexus One brand new for about a week, had it rooted first thing with the HTC Desire ROM...it was running perfectly
After the installation of the shield was complete I reinserted the battery and hit the power button. The phone booted straight to the bootloader (aka white Robots on Skateboards screen). Funny thing, I was unable to navigate the bootloader (vol up/down) without fiddling with the trackball first by pressing it a couple times) Anyway if I would reboot the phone via bootloader it would return...power off the phone it wouldn't power off just reboot to bootloader.
In this mode I could still use fastboot perfectly and I could enter the restore screen. At this point I kept attempting a reboot and it actually went through at one point and did a full boot to the OS...when I powered down and booted up again however, it was back to the same issue.
On the modaco forum they suggested I flash an alpha2boot.img as the boot image replacement for r21 desire rom as a fix, I tried this method with no success. Since, I've factory reset the phone several times replacing it with various ROMs (currently running stock) none of it fixed the problem.
I also found a way to brute force the phone into safe mode via the fastboot command in prompt: fastboot-windows reboot Using this command the phone successfully reboots, albeit into SAFE MODE. In safe mode the phone works perfectly in every way. I'm just limited in that I can't install any applications and I can't reboot properly (without a computer and command prompt).
I was doing some research on the forums and read the problem could be with the trackball. It would make sense that the phone could only boot to bootloader if the phone had the key press for the trackball triggered somehow. That said, the trackball functions perfectly when operating the phone in safe mode so I doubt this is the issue.
Another idea is that the phone is stuck in some state in the SPL or bootloader...I was wondering if there was anyway to reflash the SPL or bootloader to see if I could resolve the issue that way. (how I would do this, I have no idea)
Any help, suggestions, or advice is very appreciated. As I already unlocked my phone I have a feeling I am out of luck for warranty though I would pay for HTC to repair it if they could. I would prefer to fix it in the software however and not send it in.

Reflash the stock ROM and see if that helps.

He said he's running stock rom...
@ OP, if everything was absolutely perfect before putting the shield on, and everything to crap immediately after finishing the shield, then obviously something went wrong during the install.
The obvious yet unfortunate conclusion is that some solution got inside or something, most likely inside the trackball. =\

Detail exactly what you did when you installed the invisible shield.
Did you get you phone wet at all?

Got the front of the phone a little wet and I'm guessing some did get in the trackball. That said, I do invisi shields every day for my job and never had an issue with any phone...wouldn't it be ironic that mine was the one that got screwed up.
I think it's interesting to note that the trackball still works perfectly when the phone is running in safe mode, no double clicks or anything like that...possibly a sensor was tripped?

So I called it quits on fixing this phone and I'm sending it out to HTC does anyone know how I go about getting restore back to factory settings?

Well you can't relock the bootloader, but if you can use fastboot when your phone's on the booatloader, you can use that to wipe the phone.

Oh wow, sorry to hear it.
If your phone will not boot without the help of fastboot, I wouldn't worry to much about what state Android is in (factory, or custom rom). HTC will attempt to boot the phone, toss it in a bin, and then send you a replacement.
Or that is my assumption anyways. A friend had a similar issue; he unlocked his phone and decided after flashing the Desire rom, that he wanted to stay stock with what came on his Nexus for a while. After flashing the stock images back, his phone looped into bootloader. Off to HTC it went and within a week he had a new phone.
Best of luck!

Sorry to post in such an old thread, but I'm having the exact same issue. Even the part with the invisible shield. Didnt install it myself, the idiot at best buy used too much of the liquid I guess. Did you send yours in or what? I managed to get the phone to work for about a month then it started acting up again today. Wont boot into anything other than safe mode, or fastboot. When it boots into safe mdoe, the phone turns off within a few seconds then goes straight to the boot animation. Would love to get this issue settled, really annoying

i am having same problem. fasboot doesnt even find my phone. i got into safe mode but when i turned it off and back on it went back to fastboot

Same
I am getting the same problem! this really sucks. I think the phone might have gotten a little bit wet, just a few drops of water, and that may have caused this. Should I just call HTC and send it in?
btw, the phone was working fine, even with the very little moisture that was wiped from it. But, I took out the battery when I got home, and this happened.

so is this because on invisibleshield? cuz i just ordered mine today!!

I think its from a little bit of moisture getting into the trackball. I've been doing many "tests" trying to figure out the problem, and my almost final conclusion is the trackball not working good. Most of the time I try to start-up the phone i get into safemode, and once I have gotten into the normal way of things, but the trackball wasn't working well. I think I might have to cal htc, and that sucks because I am going out of the country in 4 days... I won't be able to take my nexus if I can't come up with a way to fix it myself.

I DID IT!
Well, I think I did.
My theory that moisture was the cause of this bootloader stuckness is quite correct. I took a towel, and rubbed the trackball to it for a good 5-10 min, then I did it for another 5-10 min wiping while pressing down on the trackball. I'm very sure that there was some moisture extracted from the device. The trackball is working now. I now do not have to call HTC or send it in.
I kept on booting into fastboot and then recovery, being unable to press buttons, but then I rebooted again into safe mode, where the trackball wasn't working either. I kept moving around the trackball, and then I figured it out, because I felt a slight bit of moisture. Now, it boots up normally, I can access the recovery, and all selection is working.
But, I have a bad feeling that this problem will come back to haunt me. It's good for now though.
Phone is working great as usual.

Can confirm the same issue.
Drop of water on the trackball.
Rebooted into an unresponsive fastboot.
Fastboot reboot command from the computer got me into safemode.
Rolling the trackball while pressed fixed it, the phone boots properly now.

Not booting (into anything)

My phones battery died over the weekend, I got it charged back up, the phone was acting real sluggish so I restarted it, came back a few hours later and noticed it was still on the white HTC screen, I watched it for a few minutes and noticed it would sit on this screen for about a minute, then go dark, then back to the HTC screen and we go round and round.
I tried hboot, all the options do this. Fastboot, recovery even factory restore all trigger this infinite loop...
What has happened? How can I fix this?
Note that it was a stock phone, no mods, no custom ROMs or anything else. It was OTA updated to ICS about a week ago, and has been fine since then.

So can you get to the bootloader and send fastboot commands?

Sorry I am not a modder or anything like that, do you mean select the "fastboot" option?
I tried running fastboot reboot from my PC while it was plugged in and my phone was in the hboot area, and it just says "waiting for device" and never does anything.
If I select "fastboot" from the hboot menu the phone restarts, a bar goes up the side of the HTC screen then about 30 or so seconds later it goes black and repeats process.

Ah, yes I can. I figured it out, plug into USB, select fastboot, then it goes to USB. I was able to reboot the phone.
EDIT: Tried running the update from HTC's website, took it about 5 - 10 minutes or so. It completed without issues, however the phone is still doing this infinite rebooting cycle...

You mean the RUU? And for ICS? That is supposed to be the ultimate method to unbrick and return to stock. Sounds like the OTA messed something up. When you say go dark you mean the screen goes of then it comes back to the HTC screen? This is probably obvious but have you tried a battery pull? Taking out aim card anything is worth a shot.

Yes the RUU update from HTC's website. The phone started this morning without issues. Then after a restart it starts the whole cycle over again.

[Q] HTC Velocity dead?

Hey guys, i've had a look around and i'm in a hurry as im heading to melbourne in an hour or so.
My phone went flat last night and now does nothing..
if i take the battery out for a few seconds sometimes the amber light comes on for about 3 seconds then goes off.
other times it will flash on/off for about 10 seconds then stop.
i cant get into anything, hboot, or even a white htc screen.
Also the weird part is the touch buttons down the bottom vibrate when i press them, however nothing happens?
so ive come to the conclusion of
1. screen is dead? (no liquid damage and no cracks)
2. bricked ( i used the stock ics rooted ruu)
3. battery is dead?
basically i need to work out if i can get it back to stock or what im to do?
maybe someone knows a shop in melb that can do warranty jobs (if warranty will work) any tips would be great right now as i have no phone!

Also how am i going to backup my stuff????

finally got into hboot and did a factory reset. will see what happens
factory reset didnt work so now im trying to get back into hboot

Get into HBOOT and try to RUU it.
Have you installed a custom recovery/ROM? If you have and can get to HBOOT, boot into recovery and reflash your ROM.

I got int hboot once but can't seem to do it again will try again when I get home hopefully I can I have installed the custom ics stock rom that's rooted

took into telstra and tested it there, with a new battery it worked, so now i have to wait a week for them to get a new battery for me. at least it wasnt the phone!!

[Q] Phone wont boot, battery issues?

hello all, so I've had my vivid for about 6 months now. it's unlocked, I just S-off'd it, the whole shabang. i've been flashing new roms and having some fun with it. last night I put a new rom on it and made sure everything was working, then i took it off the charger cause i was going out for a bit. the phone died (no big deal because i wasnt in the process of flashing or anything) but now it wont come back.
i put it on a wall charger and the orange light wont come on, the thing is legit dead. AT&T sent me a new battery that should get here tomorrow or tuesday. once i get that everything should be working right? or do i have bigger problems on my hands?
thanks a bunch

i have actually had it happen where i had to reflash recovery so it would charge when turned off. IDk how the hell recovery had anything to do with it charging when off but it fixed it....

well right now the phone wont even turn on. no recovery, no bootloader. once the battery comes i will make sure i am still unlocked and S-off, then reflash recovery and start from scratch rom and kernel wise
EDIT: it came on briefly then died. i'm convinced the battery is just toast

EDIT: well i unplugged it then plugged it back in and the screen came on slightly. it's still black but i can tell it's illuminated. i guess i'll just wait for tomorrow and hope that i'll be up and running again

thats exactly what mine did

If you search... You'll find a thread where they talk about this...
The recommendation was to plug it in... Wait for the orange led to stop flashing... Touch all the capacitive buttons... See if the light comes on... If not unplug and plug back it back in repeatedly until there is enough snot to keep it on...
And if you believe in god... Pray

Please Help: Rooted & stock. OS won't load unless the charger is plugged in

This is a very strange problem. I never saw anything similar in my life and I searched for someone with a similar problem but I cannot find anything. So I am posting this thread, maybe someone here knows what I should do.
This tablet has been riddled with problems, but this one makes it close to useless. I had several problems since I got the tablet where it won't wake up after sleeping and you had to reboot the thing, where the dock is not available after sleeping and you have to undock and redock it, where the battery drains while sleeping etc etc. Annoyances but I can live with them. I know there is a fix for the dock and you have to send it to Asus, but shipping is expensive so I'll learn to live with it.
This problem though.. this is a big one. So just to clarify, the tablet is rooted with the original 4.4.2 ROM. I did not make any changes in the past week. Yesterday morning, I woke up and used it normally. Later that morning I unplugged it from the charger and that's when I noticed this problem. So while it is connected to the charger the tablet will function normally. After I unplug it the tablet will freeze after a few seconds, reboot on its own and then it will boot until the icons start coming up. Usually after this you get the lockscreen, but instead the screen will black out. After a few seconds the icons start coming back and the the screen will black out again and so on. This loop will continue forever unless you plug the charger in. When you plug in the charger, the icons will come up and after you get the lock screen (instead of the black screen), and you can use it normally. If you unplug it again, the boot loop starts again. This behavior is the same whether using the dock or not.
I don't want to do a factory reset just yet if I can. Last time I did a factory reset, the tablet would not boot and I had to send it back for a replacement. When I get to the fastboot screen, trying RCK I get the dead Android with the red exclamation, and cold booting does nothing.
Any suggestions please? Any kind of log I can get to help? I can post a video if the problem is not clear.
Thanks.

Hi, to start this reply, I'll let you know that I am no professional at any of this stuff. I am a regular person that has had experience with flashing ROMs and whatnot. In my opinion, this seems like a software (maybe hardware) related problem. So there are a couple of options you have here.
1. Are you still under your warranty period? You could return it and get another one (easy fix)
2. You could try to factory reset, and if it doesn't turn on, rma the tablet (which it sounds like it may be cheaper to just buy a new one anyways)
3. You could try unlocking the bootloader. Then install a custom ROM (kind of risky, but might be less risky than #2)
Overall, you are not in an amazing spot with your tablet. It saddens me to see all the problems with asus's tablets. I have been with them since the transformer prime because of their laptop like tablet makes it easy to use in school, but its always been a struggle staying with their lineup. I have returned their tablets multiple times. Please update when you can

If you have a microSD in the tablet take it out and try to boot it. I have seen the weirdest problems because of a card on the fritz....
Second possibility: Hardware. The behavior (working fine when connected to power) seems to indicate it doesn't get the charge it needs from the battery. Could be that it is going kaputt. It's not totally fried but enough that the tablet does not get a reliable charge from the battery.
Third option would be to reflash the firmware. That would eliminate a software problem. You will loose root if you do that...
Since you're still on the original firmware, I assume you did not unlock the bootloader and rooted with Towelroot - correct?
Whatever you do, backup everything you care about off the tablet now....

Thanks for your replies/suggestions. I could not use towelroot as it was on 4.4.2 (I think I read it is not possible). The bootloader is unlocked. This is my second tablet as I had returned the original one. I tried putting Cromi-X on it, and when I got to the step to factory reset it (using fastboot), the thing just was stuck in an endless loop. I could not even get to fastboot and my PC wouldn't recognize it. All it did was boot to the ASUS logo (and the message that the bootloader was unlocked) and reboot.
So this is the replacement unit and the charging issue was the problem. I say was because believe me or not the tablet is now smashed to bits. Since it must always be connected with a charger to work, I was carrying it around docked as I usually do and forgot that it was plugged in. I have resorted to an extra long extension cord with the charger plugged in to walk around. Anyway I forgot it was plugged in, the extension cord reached its limit and the charger cord yanked the tablet out of my hands and onto its side - screen facing away. I sweared, feared the worst and went to pick it up. The good news is that it still boots. The bad news is that the screen is completely smashed. The back cover is bent at one corner and the glass is smashed at that corner with cracks running to the other side. The touchscreen is not working anymore either. To add insult to the injury the tablet still only boots up with the charger plugged in..so there's that.
I don't know what to do now. I have contacted ASUS for a possible RMA but got no response yet. The thing is I don't feel like spending more money on it given the problems experienced. A screen with digitizer on ebay is about €75..so not exactly cheap.
I guess we can close this thread as it is now pointless. I hope no one has to go through my experience and that maybe it was a one off thing.
Thanks again to whoever replied. I appreciate it.
