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
Hi,
I wanted to debrand by phone so i did the supercid thing to change from t-mob_005 to 1111111, then i installed latest HTC rom (and ver 4.0.4 software number 2.21.401.10) which in turn upgraded hboot to 1.14 and baseband to 1.06s.
Now, ive got my new token id and resubmitted to htcdev and then installed the new unlock_code it gave me back, all seemed to go thru ok, came up with the screen about voiding warranty, use volume to select yes or no, ive selected yes and it then reboots... but still the bootloader says relocked. ive tried the same over and over and even gone thru the process of new token id etc again but still i cant unlock it.
where am i going wrong?
Hi I had the same problem how I got over it is let the phone boot up enable USB debugging and disable fastboot in the power menu then completely power off the phone
Wait a minute then reboot once you get back to the home screen press power and restart holding volume down when you get to the bootloader screen it should now say unlocked once more

1.Shutdown your tablet
2. Hold Power + Vol Down until a message appears ("Press Vol. Up to enter RCK (5s)")
3. Press Vol Up .
4. Android Rebot laying down (red lable)
Please help.
Cannot into RCK. Need install Recovery or not?
Thanks
Well, what are you trying to do?
If you want to install a custom ROM or a custom recovery, you need to unlock your device first.
When running stock ROM, why do you need recovery?
If you have issues with stock ROM ASUS support should be helpful.

If you have stock ROM and you hold power+Vol down then Vol Up...it will boot into stock rom recovery...which is the android robot laying down. Nothing wrong there...that's what is supposed to happen.
That is the same way to get to a CUSTOM recovery such as TWRP but in order to install that, you need to have your tablet unlocked using the Asus APP unlocker. This is downloadable from the Asus website. Read carefully before you install it...if you don't care to install custom ROMs, then dont bother.
If I have stock ROM ICS 4.30 and unroot , unlock and I hold power+Vol down then Vol Up... It only show data wipe and android icon.
Some one in this forum said that also have a USB icon. However, I cannot find it.
How to show the USB icon? Need update to JB loader or unlock the table.
Anyone can help?

If you are on stock ICS ROM and you hold power+vol down, you should see wipe data, the USB icon and Android icon. Use vol down to move the cursor to the usb icon and then use Vol up to select...

What do you see when you hold power+vol down?
No you don't need to update to JB to see this...JB has 4 icons, ICS has 3.
Is USB debugging ON?
It is possible you may have to unlock to get the USB icon...
I forget since I did it awhile ago...

Before you proceed with the following, it is really important to tell me what you eventually want to do.
If you don't care, then go ahead and try first:
1. Go to settings, developer options, make sure USB debugging is checked. Then do the power+vol down to see if USB icon appears.
2. If that doesn't work, try settings, backup and reset, then reboot with power+vol down. Warning: This resets everything so all your data will be erased.

xxboarderxx,
Thank you for your hlep.
point 1 and point 2 have already try. Still only 2 icon show and no USB icon.
I think it should be need to unlock the table or update to JB.
I just want to know other user have same issue or not before I unlock or update the table.
Uhmmmm. The extra 2 icons show when you upgrade to jb. The jb upgrade includes an upgrade to the bootloader which is where these icons appear.
That being said if you don't intend to unlock or use fastboot mode, then you don't need these and perhaps you should stop trying to mess around in sensitive areas. If your intent is to unlock, root, update to the latest firmware and or load a custom ROM, there is a guide in the general section which explains all of this starting in ICS and moving up to jb. Go find it.

Two extra icons appear in JB yes but the usb icon should be there even with ICS. I can confirm since I soft bricked my tablet on ICS when I first got the tablet and needed to fast boot and nv flash using apx to get it working again... He's messed something up and the only way to really get everything back is to restore to stock. However he won't tell me what he intends to do so I can't really help him any further...

As I see it, the only reason to unlock your tablet is to get access to fastboot, right?
So it seems reasonable, that the USB/fastboot icon is not showing on a locked device.
Might be all quite as intended.
Unfortunately I can't check this, as my tablet is already unlocked, but it seems like a good guess.

You might be right. I can't remember if I had usb icon after unlocking bootloader or before. I just know there is a possibility of having 3 icons with ICS.

Android on back is stock recovery with no file to install found, correct response.
Thank you for all.

Good choice!
Ok.. I'm about to lose hope, please any creative ideas will be much appreciated..
I think i did a big mistake trying to update to the latest nightly release of CM 10.2 using the auto-update feature of cm 10.1...
The end result is a bootloop, gets up to the CM rotating animation for a few seconds and reboots.
on top of that:
unable to get into bootloader using pwr+vol up nor vol down
unable to access device using adb nor fastboot - shows no device connected
the PC does not recognize the device though there are drivers installed, the charging LED lights up but no PC activity
all of the solutions i've seen assume either the recover/bootloader is available or the phone is accessed via fastboot/adb.
in this case neither are correct....
for some time i wanted to upgrade to htc one but not yet....
please help
Press and hold power until the phone shuts off.
Then let go of power and press and hold volume down until bootloader comes up.

tried it again several time, but as I said it doesn't work.
I get a black screen (not the CM animation) and than reboot all over again.
You could try letting it drain completely. Then charge a bit and try again.
Is your phone plugged in while your trying? My phone will not enter bootloader while its plugged in.

You are mostly likely not performing the button combo correctly. If there were no bootloader (hboot), the screen would not be coming on at all. Not getting into bootloader is almost always a case of not doing the button combo correctly. The one possible exception, is if your volume rocker has failed (and simply not registering the vol down being pressed).
Make sure you hold vol down, and do not let go until the while bootloader screen comes up.
Recovery is a different story, as you can indeed not have recovery installed, and the phone will still function. But hboot and recovery are 2 different things.

I wish it was the case,
when i try to go into hboot the device instead of going into another boot until animation cycle, goes into black screen boot cycle. which means most likely that the action (PWR+Vol) does have an effect otherwise it would have continued to go into same boot cycle through the CM animation..
besides there is a recovery installed, or at least was...
is there anyway to re-install the hboot part without the hboot/fastboot availability?

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.)
