Hi,
I have an Samsung Nexus S [not rooted] with a broken power button (stopped working after I updated to ICS). So for a couple of months, I was using the "pull batter" trick to power on and off my phone.
Now I am stuck in a bootloop and I can't seem to get out of it, despite howmany time i try to pull out the battery.
I manage to enter into the fastoboot mode screen, but then my volume buttons won't work and I can't scroll up and down the menu.
Is there a way out? I am really a noob at this and haven't rooted an android phone before. Please help!
Thanks
i think the best think is to unlock the bootloader and doing that it will prompt to you asking for erasing all your phone (sdcard included), maybe this hard factory reset will help you bcz like that ur phone will be back to stock ics.
to unlock your bootloader (wich is the first step to root, if u want to) do this:
download this (the entire nexusrootics folder): https://docs.google.com/open?id=0B7O2O1p4iWXTWWxha0pUcXNud2s
put the folder on the root of your hard drive of your pc (for example mine is C:\)
then install the drivers (wich are in the downloaded folder), so plug your phone go to driver management and choose to select the fiolder and select the usb_driver and choose ADB... (first one)
then click windows button+ R and type "cmd" (no "")
now type "cd.." (no "") to go back to the root of your hard drive and type cd (name of the downloaded folder)
now type "adb devices"; if a number appears it means that your drivers are well installed
after that, type "fastboot oem unlock"
on your nexus a question will appear to ask your if your are sure to erase all your content, use the volume lockers to say yes. (if your volume buttons dont work here i think u are stuck)
NOW YOUR PHONE SHOULD BE BACK TO STOCK, WITH THE BOOTLAODER UNLOCK BUT NOT ROOTED so it's safe for warranty issues
please click the thanks button

to lock it back just type "fastboot oem lock"
I got the same problem, yesterday the power button was not functioning properly. And after a couple of battery pulls, I can't start the phone unless I put a usb cable in. The phone starts but it is stuck in bootscreen. If I hold volume up button and connect usb cable + put the battery back in I can get into bootloader (Rooted and unlocked) but I can't navigate in boot screen with volume up or down, and pressing power button does nothing, which btw is clicking when pressed as usual.
I think the powerbutton is continuously pressed, and thats why I can't navigate or execute any commands in bootloader.
Any help to this problem would be appriciated, since I'm working abroad and using this phone as gps here and have no backup phone at the moment.

I got the exact same problem.
Can't backup even through clockwork Rom Manager mod, because when in recovery the power button might be interfering with the scripted backup....
Well mine has weird issues
Every so often if I click the power button it doesn't do Anything or brings up shutdown menu

I'm in the exact same boat. What the hell did Samsung make the power button with??? Mine died on me barely 6 months after purchase of the phone. It's pretty pathetic.
I would like to know how am I able to browse bootloader screen if my power button is dead??
Mine did the exact same thing, I was online chat with Samsung for warranty and all of a sudden the volume buttons started working in fast boot...and amazingly I pressed power after select recovery and it works...right before the volume buttons "unlocked " , I was kinda tapping on the power button trying to get it to do anything, then I saw the USB init and whatnot

okay guys looking for the easiest way to boot into recovery / bootloader
would prefer both physical on the phone and adb commands
if you would be so kind
Volume down+power = BOOTLOADER
adb commands are the same across nearly every device
adb reboot recovery
adb reboot bootloader

thanks, i never had to use adb with my captivate or infuse so i figured i would ask .
also for some reason sometimes volume down +power wont work to get me into the bootloader.
I use Quickboot...it has many reboot options, including reboot into Bootloader and Reboot into Recovery.
Another simple way is to pick restart from the power menu then just hold volume down as the phone restarts.

You have to hold volume down the entire time until it gets to the bootloader. On the Captivate you could release it as soon as the splash screen came up but on this HOX you have to continue holding.

If the phone is powered off when you want to go into bootloader, you have to make sure "Fast boot" in Settings>Power is unchecked.
Going into bootloader using power+vol down requries the phone to be fully powered off or a reboot. Fast boot is actually just a deep sleep mode and not a full power down.

That method never seems to work for me. Holding the vol down immediately after selecting restart, or even holding the vol down while picking restart, it just boots normally.
I have to power down (with fast boot unselected in Settings>Power) then hold vol down while pressing power button, in order to get to bootloader.

I am trying to boot my samsung captivate into the boot loader. I've tried the physical key combos mentioned in this thread and there not working.
I tried using ./adb reboot bootloader but the phone does a regular reboot.
I am able to get a splash screen with that says "Download" and has a picture of the Android shoveling, by pressing both volumes and plugin in the power.
But if i do this, the device is not visible when I used ./adb devices
The question is how can i get this to reboot into the bootloader preferably from the terminal so that I can unlock it and install CWM.
Any advice would be much appreciated!
Good job finding the wrong phones forum and digging up an old thread to post on

This forum is specific to the HTC One X/XL. You need to go to the forum specific to the Samsung Captivate. The key sequence is likely different, and getting advice from people with a different device can quite possibly lead get you the incorrect info.
Also, as mentioned above, try not to dig up old threads from 7 months ago.

Quick question: I'm trying to reboot my android STB in bootloader mode to check its lock/unlock status... Obviously I can't use the Vol Down + Power button in a STB...
So I tried "adb reboot bootloader", which didin't seem to work. I mean, it powered down, then powered up in a screen with the brand's logo, but nothing else happened, and the command "fastboot devices" didn't find any device either (while before that, "adb devices" showed the device normally). Also, I didn't get any unrecognized devices under Device manager which would denote that a new "device" got connected into the system...
I then tried "adb reboot recovery" which works fine...
So what does this situation mean for my STB?
Hi, I bricked my phone somehow by either rooting my phone or upgrading it to gingerbread. Regardless the situation, I was doing it to try to remap my broken power button with my 3d button. So now, I think I bricked my phone, because everytime it gets to the logo it just stops. I flashed from my computer before, but it didn't work. It's because even if it did work, i've to go to recovery mode to wipe the data. However, my power button is not working, so there is no way i could get into recovery mode. Anyone got any idea, thank you.
Try using the LG Mobile Support Tool

Write down the IMEI and Serial Number of the phone then start the program, go to Customer Support (the second menu option from the left - I have it in Italian so I'm going blind here) then choose Emergency & Recovery Mode (the last option). You'll be asked for IMEI or Serial Number. Type them it and be patient. Just be sure that your phone is charged above the 40% and that you don't run the LG PC Studio.
i'm not sure if it works:
install adb(google it)
pöug in usb to phone and pc
when the lg logo apears type in cmd:
adb reboot-recovery (or reboot recovery)
if this doesnt work
press at the lg logo vol up + 3d button
and type in cmd
adb reboot

Update: I messed around with fastboot a bit more and managed to brick it entirely. It's stuck in a boot loop now -- it won't even power off -- and there's nothing I can do about it, so I just took it in to get it replaced.
Hey guys, I know this thread is very similar to others that have been posted, but I've already looked through them and haven't found anything that works for me yet.
My phone was already running rooted stock with TWRP for the recovery. I tried flashing CM10.2 but it was for the wrong model (I downloaded D802 but my phone is of course D801. Oops). Upon reboot, the LG splash screen appeared and then immediately went to a black screen saying
Code:
Fastboot mode started
udc_start()
When I attempt to turn the phone off it just reboots to that screen again. I am still able to use fastboot, and have tried wiping the phone and re-flashing TWRP. It doesn't throw any errors but I still can't actually boot into recovery. I can't use fastboot to flash a new ROM onto the phone though, since it doesn't like .zip archives apparently, and I can't find a .img file of a ROM anywhere.
When I try to use flashtool as described here http://forum.xda-developers.com/showthread.php?t=2541087 it says the device is not connected (probably because it's not in download mode?).
Any help would be much appreciated. All I need to do is get into recovery, it shouldn't be this hard.
That's the same error I got a few days ago when I mis-flashed a new recovery (oops. and be careful when you use 'dd', because a typo can nuke your recovery). I'd get that error message if I tried to boot into recovery, but if I just let the phone boot, it would boot fine. It was easy to fix, but that was because I just used Terminal Emulator to re-flash recovery.
Your best bet might be to go back to stock. Try this thread.

I'm not in a boot loop, as I can power off and it will stay off. But I am stuck at the Fastboot mode started screen (I can't get download mode to come up). When I do try to get into download mode it flashes for a second, but then goes back to the fastboot mode screen.
I'm hoping to find an image that I can use the fastboot flash recovery command with to re-write my recovery partition.
Any suggestions on where to find this image file? Or am I going down the wrong path?
Thanks,
Joseph
Did you get it to work? I am in the same mode.
I'm stuck here as well. Looking for a fix
Did you guys find a fix? I need help with this...
similar thing here with me
any solution
i cant boot at all, not into download mode, nor recovery,
got this too because i was installing a note3 rom to my d800, acciodentally of coarse. i managed to boot to twrp by doing the power and volume down technique. and from twrp i restored my recent backup
To anyone still stuck in this situation (reboot loop, no recovery etc):
- Unplug the phone from the USB cable
- Hold down the power until the phone turns off
- Wait a couple of minutes with the phone off
- Now hold power and volume down buttons
- When LG logo appears - release power and volume down and hold them again
- When you see a white screen with "reset to default instructions" -- do what it says, meaning pressing the power button a couple of times
THAT should work.

All I did was hold power and volume down until the LG logo came on (not when it flashed for just a split 2nd) and then pressed and held power down again and it came to the white screen. Then I pressed power 3 times and got into recovery

Not sure if you've tried this. To power off fully, press and hold the volume down and power buttons. Do not let go of the buttons. The phone should turn off and the LG logo should appear. Continue holding until after the LG logo disappears. The phone should be fully off and won't turn back on at this point. If you don't see the LG logo, just keep the buttons pressed for about 10-15 seconds and you should be fully powered off by then. You should be able to enter download mode from here (press and hold volume up button while plugging in USB from computer). If you are able to enter download mode, then use the LG mobile support tool in my thread and follow the instructions. This should flash the latest stock system to your phone. If that doesn't work, I have a link to an alternate method for flashing the latest stock system on your phone. Hope this helps.

3. While holding these buttons press the Power button for a short while.
4. Release held keys when you see an Andoid image.

Power down your device.
Press and hold POWER + VOLUME DOWN
After the Sony logo disappears, release the POWER button and continue to hold VOLUME DOWN for 3 seconds.
This will allow you to boot to recovery.

I may have given you incorrect steps and that's my fault. I was reading about a different device. My bad. Try this:
Power off your device.
Press and hold VOLUME UP + POWER at the same time.
Release all buttons when the Sony Xperia C3 screen flickers and in a few seconds the Recovery screen will appear.
You can also try this:
Reboot your phone, as it's rebooting, press volume down + power. You should then see the Android robot after restart, release buttons and press camera shutter.?

Okay, quick question. Have you installed a custom recovery? If not, your device was not shipped with a stock recovery in and therefore you will not be able to boot into recovery.

Do something for me first... Let's make sure your ADB fastboot is working properly.
If your device will boot normally, navigate to DEVELOPER OPTIONS and make sure you have enabled USB DEBUGGING.
Next, open a COMMAND PROMPT window and type:
adb devices
If the adb daemon is not running, you will see the COMMAND PROMPT say that it is starting the daemon on a certain port number.
Type this again:
adb devices
Your COMMAND PROMPT should return with a list of attached devices with your serial number.
Next, type this:
adb reboot bootloader
If it's working properly you should be booted into the bootloader and your LED should be a solid blue.
If you want to boot to the bootloader with the hard keys then do this:
Power off your device
Connect the USB cable to your PC
Press and hold POWER UP and plug in the USB cable to your device while still holding POWER UP.
This should boot you into the bootloader with a solid blue LED.
Let me know if these steps are working and post back with what you find

yes this works. i mean the volume up and usb cable let me go into bootloader. i see blue led and device is on debuging mode but i am unable to get into the device since i forgot the pass code.
this is why i want to get into recovery. i want to wipe data so the pass code will be removed.
beacuse of the pass code i cannot send adb commands through the lock screen.
anyway, there is somthing i can do to wipe data or flash a new rom or remove passcode through bootloader? (the black screen with the blue led)
