hello frnds,
i am from india (duh) ...my friend bought a galaxy nexus s two days ago..
she had it up an running and it was working as it should.. but yesterday when she woke up..what she saw was that the phone won't boot up and a it shows a lock sign on the boot screen below google and that it was heating up badly... even the pc is not detecting it..i have the phone right now and i promised her that i'll fix it...
what should i do to keep up my promise!
bootloader is locked, phone won't boot
Hello,
The lock simply means that the bootloader of the phone is currently locked (as it is from the factory).
If it won't boot past the Google screen, try removing the battery of the phone for 10 seconds, then trying again.
If this fails, remove the battery again, replace the battery, hold down the UP volume button while pressing power until you see a green android screen. If you can see this screen, then use One Click Root 5.1 in the Development Thread for Nexus S or Nexus S 4G.
hmmm..
thank for the relpy,
well i have tried all that stuff i.e removing the battery for 10 sec..(didn't work)...
wen't to recovery mode(the green android thingi...) and tried recovery option won't work..
do you mean i should flash the firmware again by using one click?
thanks in advance!!:angel:
The lock sign means that the bootloader is UNLOCKED. If you didn't see the lock it would mean that the bootloader is locked (stock). The recovery option won't work because you haven't flash any custom recovery. In fastboot mode (volume up+ power button) it should say: LOCK STATE - UNLOCKED. This means that bootloader is unlocked. Use the toolkit (found in nexus s android development) to flash stock image.
Someone tried to do stuff to the phone and messed up.
thanks
i will try this let you know.:fingers-crossed:
thanks for the help:good:
What causes this though? I have codename jb And cwm 6 on my device and it randomly gets stuck on the boot screen through out the day

Hey ppl.
I got a Nexus S and his power button does not work for a week now. Since i got it still on warranty i decided to get it to samsung service.
I was using SlimBean so it was ok with volume rocker as a wake the device action. Since Samsung wanted the phone to be stock and locked i decided to do it. I found the stock rom, i flashed it, and here is when the problem started. I flashed the rom the way i flashed every other "custom" rom, via ClockWorkMod. Then, trying to also lock the bootloader i found this. I installed the device drivers again etc etc and when the program says "Checking Fast Boot Status" everything stops. The phone is not responding (can't move up and down with volume roker) and i have to pull the battery to reset it. Thankfully when i put the battery back in the phone starts up itself so no need for power button
So what can i do? Whats wrong with my bootloader?? Is there any way to install a custom recovery again, to have a rom with volume key unlock and leave the power button as it is? (reminder : phone is back to stock and no superuser, cwm or anything)
Appreciate any help !
Nothing was done to the phone. It's all stock and bootloader is locked.
Every time I go into the bootloader no options appear, but If I use Nexus Root Toolkit it gives me the options. But when I use it reboots the phone and gets stuck and when I remove the battery and Check to see if it save it, it still lock.
When I try Recovery mode a little android robot pops up and quickly takes me to a blank screen. The keys like the home, back those light up.
I try to flash it but since bootloader is locked everything fails.
Hey guys...
My Zenfone 5 won't boot up. It just stops at the android screen and doesn't go any further.
I can't remove the battery as i don't have the proper tools.
how it got bricked:
I powered off my phone by pressing power button and shutdown, it was connected to my pc at the moment. i didnt wait for the charging symbol(the green battery with a lightning symbol in center) to show up, but i tried to boot into bootloader before the charging symbol showed. when i got the android screen i didnt let go the power button, so my device switched off again. once more i tried into bootloader, i didnt let go the power button, again switched off. now i hold both power and volume up to go into bootloader, and i let go power button, but it is stuck at the same screen and wont go any further.
i tried adb reboot but adb doesnt recognize my device.
Please help.
Device runs android 4.4.2 and is rooted.
Never mind...
I got it working after i hold the power button for 8 seconds and then rebooting again.
A good bit of advice: don't be hasty when ur modifying your phone. I should have thought twice before starting this thread.

The asus bootloader is already unlocked, to the best of my knowledge. (when i tried power button+ volume up while switched off, and released ONLY the power button when the "in search of incredible" screen showd up, i got into the stock bootloader direclty, which should be droidboot.)
I have two Nexus 5 (one is mine, one is my wife's) that have recently following OTA updates from Google stopped booting.
They get to the Google logo, then to the animation and at this point switch off and reboot ad nauseum.
What can I do to bring them back to life?
Never known a phone so prone to firmware issues as this phone!
If the bootloader is unlocked, you re-can flash a stock ROM. Just be aware of the fact that unlocking the bootloader will factory reset the phone which results in complete data loss.
Its locked currently.
Is there a way of unlocking the bootloader whilst in this state?

Try holding the power and volume down button together, you should see it boot into fastboot mode, you can press the volume down button till u see recovery highlighted, press the power button and boot into it. From there just try to factory reset and see if that works, if it doesn't then I'll help you unlock your bootloader with the best knowledge I can offer if u got a PC.
Try booting into fastboot mode and leave it here for about 5 minutes. If it reboots by itself, it could be a defective/faulty power button.
Flash a factory image and it will be fine. i had same problem already, just google nexus factory images all instructions are there as well as factory images.
Hi Guys, My Nexus 5 is stuck in a boot loop where it wont even get past the Google logo.
I have been searching around and have tried a number of things but nothing is working for me. Here's what I have tried so far:
- I thought the power button might be stuck down so I stripped and cleaned the whole thing. Button seems to be working OK but still in loop.
- Tried clearing cache through recovery mode. Once in recovery mode the power+vol up button will not bring up menu. It then reboots after 5 seconds and the loop starts again.
Currently I am trying to flash an OEM version onto the phone but the Bootloader is locked. Working through the guide here. I can connect to the phone. Execute the command 'fastboot oem unlock' but then when I attempt the reboot I get stuck back in the loop.
So yea that's where I am at so if anyone has any solutions for me that would be much appreciated.
Try nexus tool kit to unlock bootloader.

Do you mean the Android SDK Platform-tools or maybe the Nexus Root Toolkit? In either case the result is the same. As soon as the phone needs to reboot to unlock the bootloader it goes back into the loop and hence can not complete the unlocking.

It's your power button then nothing to do with nexus root toolkit.
I'm having the same problem, power button seems to work as it does not reboot itself
It stops in the Google logo for about 10 to 15 seconds, after which it restarts and does it again
When I do unblock the bootloader by adb and I will execute the command to reinitiate it back again to the screen with the Google logo with the bootloader blocked and thus be infinitely with the logo for 10 to 15 seconds
Anyone have any idea what that might be?
Sorry for my english.
