It won't Boot and shows a lock on the screen!!

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

[Q] Boot Lopp + No Power Button

Hey guys, I just got the older HTC One S (C2) from my sister , to play a bit around.
I rooted, unlocked without any Problem, but after flashing it just stuck in a bootloop . And I can't even escape.
Unfortunately the power button is broken and i can barely turn it on by making contact with a pin needle (works rather badly)
ADB won't find my device, and even pressing all buttons the same time won't change a thing.
Anybody got an idea or some other plan?

Beg your sister for not doing to you what you did to her phone...
Your phone will power of by pressing "Power" for 10-15seconds. Is the button itself GONE? How? Once powered of press or in your case "jumper" the "power button + Vol down" at the same time. You can release power when display turns on and just keeping "Vol down" pressed will bring you into bootloader.
You will have to try getting to fastboot. Or pay 40€ for a bootloader repair. There is no other way :/ for
As you did not tell anything about S-OFF you're probably S-ON. So you may be forgot to flash the kernel???
If flashing means you flashed a custom rom. Bootloader is working in every case.
May you post some more infos?
-Firmware / HBoot
-Recovery version
-rom/KERNEL installed
-any other modifications?
Did you face any issiues while flashing?

[Q] Phone starts in BootLoader/Fastboot mode

Hi
I have been helping a friend repair their phone after it got water damaged
THe battery has been replaced and the phone boots and can go into Android
I have since Unlocked the bootloader
Installed TWRP
Rooted it
Installed a Cusom Rom
And installed a Custom Kernel with no issue.
So In my eyes this Phone is 100% working
The Problem i am stuck with is that whenever the phone is turned on it goes straight into the Bootloader screen and the Option bit on the top (Start, Recovery, Reboot BootLoader and Power off)
Constantly scrolls through each option as though the volume key is being pressed
if i press the power button as each option appears the phone will boot into the option i have chosen
While in Android all the buttons work correctly.
Vol up and Down and the power either going to sleep or bringing up the power menu.
Any ideas would be a great help

Probably HW related, but not sure

after 3 years did u find any solution. exactly same issue happen today :crying:

Try updating to the latest bootloader. But I assume the buttons get stuck sometimes. Try smacking the buttons s a couple of times. Hope that works.

[Q] 1st gen moto g stuck in unlocked bootloader screen after wiping all data, no os

My moto g was attempting to install lollipop on my rooted 4.4 and i idiotically wiped all my data through TWRP (?) and rebooted my phone with no OS even when i was warned By a warning screen. Now my phone is stuck on the white unlocked bootloader screen and when i hold down the power button and the volume down button, it just goes back to the unlocked bootloader screen. Can i do anything? Idc about any data on it but id love just my stock phone working. Thanks for any help.

If you are still facing the problem, press & hold power + vol down button. It will turn your phone off briefly for 2-3 seconds & immediately again press & hold power + vol down button for about 5 seconds. Release it & this should take you to bootloader. And since you flashed twrp you might be familiar with pushing & flashing a rom from recovery.

Two Nexus 5 16b stuck in reboot loop!

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.
