Hello!
I tried to change my firmware (to Cyanogen via Heimdall), but it seems like I ended up screwing up the bootloader, so it won't turn on now.
Neither power+volume-down, nor power + volume-down work, it just turns button backlght on and off periodically. Screen remains off.
So is there any way to restore it without going to service center?
Thanks.

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
This phone is from Australia, locked to carrier Vodafone.
the version is s5830v.
I want to flash the ROM I need, but the first thing is that
I am unable to use the button "Home+Power" into recovery mode,
and "Home+ Power+Volume Down" into downloading mode.
Every time I tried to use these buttons, the result is go into the system straight away, just like turn the power on.
I assume this function keys is disable by the carrier.
Is there any way I can regain these back.
Thank you all.
nobody knows?
it seems a tricky problem.
Try power + home + volume UP.
was with the original rom lg. and then went instalr the recovery of the cyanogen rom manager app, and then hung up the phone and now the message appears in red at the top of the screen
"Critical Failure: Unable to start Kernel.
Unrecoverable bootloader error (0x00000002)"
and I can not get into download mode to install the original rom again.
and now what do I do? I lost my phone?
you flashed cwm without unlocking your bootloader. re-flash latest jellybean kdz file for your phone using http://forum.xda-developers.com/showthread.php?t=2069723, then read some more about unlocking bootloader, and then start again.

but now I am unable to get into download mode on the phone. is
" Now just hold down vol - key ( hold hold hold dont release !!!! ) and plug the USB cable until you get screen like this :-"
he does not. whenever I do this it only vibrates strong and goes to the screen with the error message. I do not know why that. remember one time it happened to me already but can not remember how I resolved it is possible to even lose the download mode?
Its not possible afaik. Are you sure you are holding only vol - key and plugging in? Dont hold power key!
yes, I'm almost the whole day trying to get into download mode by pressing volume down + connecting the usb. and whenever it vibrates strong and hangs on lg logo. tried to volume up + usb connect. and no download mode. I'm going crazy with this phone. otherwise hesitate to hard reset? or other shortcut to download mode?

hard reset wont help you, as far as i know, you somehow need to enter s/w upgrade screen. did you try it with battery out?
he battery of the same error, and no battery it does nothing, or vibrate, or flash screen, nothing happens
Will I not be able to see my optimus running again? :crying:
it is not possible to load the kernel, what could I do?

Hi Raphael20 and everyone else,
Did you manage to figure out a solution to this? I have the same issue, i.e. cannot start my phone by holding the power button. Not even when people suggest to get to the S/W Update screen by holding the Volume down + plug into the computer.
I got to this error when I tried to do a factory reset. I installed the ClockworkMod Recovery. Then the factory reset via Volume up + Power button gave me the "Critical Failure: Unable to start Kernel" error. I somehow managed to get access to my phone by holding the Volume down + plug into the computer. Then tried to do a factory reset via the system settings of my phone. My phone restarted and then gave me the "Critical Failure: Unable to start Kernel" screen of death! Now Volume down + plug into the computer gives me the "Critical Failure: Unable to start Kernel", no matter whether I have restarted my computer and I have tried another computer. It seems that the bootloader is wrecked.
Does anyone have any suggestions?
Thanks!
Hi, after updating my firmware with the Sony Update program, my power button doesn't work. It still turns the screen off when I press it, but holding it down no longer gives me the usual menu letting me turn off my phone
Is there a way to reboot in the OS itself?
Thanks

I assume it is a software problem. Have you tried reinstalling the OS?
press "power +reduce volume "
Hi, I sorry to bother anyone, but I need help because my phone is not responding and I don't know what to do.
C6603, rooted, dual recovery installed, bootloader unlocked (I think)
So here's what happened. I very successfully installed the existenz ultimate rom on my phone. It was a wonderful rom and everything was going well. However, I accidentally dropped my phone and needed to send it for repair. Before sending it to the shop, I decided to do a factory reset using the option in recovery mode.
When I got the phone back from the repair shop, I wanted to install the same rom. What I did was download the rom installer and then install the zip file using the recovery mode. I went through the AROMA installer and everything, So I thought everything was going fine. When the phone rebooted, it showed the SONY logo, followed by a permanent black screen. The screen is on, it is just black.
I scoured the xda forums and I tried several things, to no avail:
I cannot enter recovery mode.
My PC cannot recognize my phone.
Flashtool cannot recognize the phone. My phone can't seem to enter flashmode, either.
I tried holding the power button and the vol. up button, and the phone does indeed restart (no vibrations), showing the SONY logo, and then I'm stuck with the black screen again.
I hope somebody can help me!
EDIT: I managed to somehow get flashmode working, so I think my phone is fine now! What a false alarm! In case this ever happens to anyone, what I did was to unplug the phone from any source of charging, then proceed to hold on the power button and vol. up button for REALLY long, I think almost 20 seconds. This managed to switch my phone off (it would keep restarting if I didn't hold in down long enough).
download stock firmware and open flashtool & ready to flash,dont connect until it say.connect your usb cable to ur phone,then reboot ur phone when display goes to black connect ur phone to pc whith pressing vol down ,then flash tool detect ur phone and it flash,sorry foe my bad english
