Please Help Me Phone Wont Boot

I tried to Update my GSM GN to Ver 4.0.2 using the manual instructions.
I first downloaded the image for my build (ITL42F). I placed the files in the same folder as the fastboot. then followed the instructions below.
fastboot flash bootloader bootloader-maguro-primekk15.img except file name was primekj10
fastboot reboot-bootloader
(wait for bootloader to reboot)
fastboot flash radio radio-maguro-i9250xxkk6.img except file name was i9250xxkk1.img
fastboot reboot-bootloader
(wait for bootloader to reboot)
fastboot update image-yakju-icl53f.zip except file name was itl41f.img.
Shows everything was ok and the phone started to reboot. I get the animation screen for 10 minutes but the phone wouldn't boot into the system screen. Please help me.

Are you sure you had the correct version? ICL53F is 4.0.2. Try using the images here.

Thanks going to try and report.

Reflash with ICL53F
Used the right image file now, the only thing I noticed was when I used the last command "update image-yakju-icl53f.zip" i got
archive does not contain "boot.sig"
archive does not contain "recovery.sig"
archive does not contain "system.sig"
Bootloader Version rimekk15
Baseband Version: I9250kk6
Serial Number:,,,,,,,,,,
Afterwards it run the image and show okay on the bottom and the phone reboot, but still just the animation is on and the phone is not booting to the system.
Any ideas please.
Joe.

From what you wrote it seems like you didn't wipe data.
Your final command should be:
Code:
fastboot -w update image-yakju-icl53f.zip

That was my lsat command and the above showed up. It seems to have ran everything but still not booting.

OK. Because your original post didn't have the -w flag before the "update image-yakju-icl53f.zip" so I assumed you didn't wipe.
Are you currently trying to flash the 4.0.2 build? If so, follow these commands exactly:
Code:
fastboot flash bootloader bootloader-maguro-primekk15.img
fastboot reboot-bootloader
fastboot flash radio radio-maguro-i9250xxkk6.img
fastboot reboot-bootloader
fastboot -w update image-yakju-icl53f.zip

Workssssssss
You are the man, thank you so much. The -w is what I was missing, now it's working again. I have 4.0.2.....
Thanks again
Joe

No problem man.

Mac OS X Fastboot Mode <Waiting for Device>

Hi, I am trying to Re-Lock my Galaxy Nexus GSM version, I've downloaded the SDK files (adb-mac and fastboot-mac) and all the image files and I am trying to execute the following commands:
adb reboot bootloader
fastboot flash bootloader bootloader-toro-primekk15.img
fastboot reboot-bootloader
fastboot flash radio radio-toro-i515.ek02.img
fastboot reboot-bootloader
fastboot flash radio-cdma radio-cdma-toro-i515.ek05.img
fastboot reboot-bootloader
fastboot -w update image-mysid-icl53f.zip
fastboot reboot-bootloader
fastboot oem lock
With the phone in normal mode I connect the USB cable to the computer, start Terminal windows and run the first command, "./adb-mac reboot bootloader" and the phone will boot into the "Fastboot Mode", then I try to execute "./fastboot-mac devices" to make sure the phone is connected and properly detected and I get nothing.
If I try to execute "./fastboot-mac flash bootloader bootloader-toro-primekk15.img" I get the message <waiting for device> and it will stay there forever.
Do you know what might be the problem ?, is there other method to do this ?, go back to Stock ROM and Re-Lock the device ?, thanks

You must also install the Samsung usb drivers. I have no idea how to do this in mac. A simple search will help you tho.

can't unroot/relock GNex - please help

I walked through the following steps to put the stock OS back on my device...
adb reboot bootloader
fastboot flash bootloader bootloader-toro-primekk15.img
fastboot reboot-bootloader
fastboot flash radio radio-toro-i515.ek02.img
fastboot reboot-bootloader
fastboot flash radio-cdma radio-cdma-toro-i515.ek05.img (Note: This one takes a couple minutes. Be patient)
fastboot reboot-bootloader
fastboot -w update image-mysid-icl53f.zip
I now have the stock OS loaded and can boot alright, unlocked. When I get back into the OS I turn debugging on and then head back to adb. I can browse to my device through the USB but get the following error when attaching to my device.
c:\android\android-sdk\platform-tools\adb shell
[email protected]:/ $ adb reboot bootloader
adb reboot bootloader
error: device not found
1|[email protected]:/ $
Further, if I run "fastboot devices" from my command prompt I get no devices returned.
What am I missing?? I need to get this device relocked to send back in for warranty quickly. I'm trying to get the device locked back up. Any help you can provide is appreciated!
Edit: Resolved now

nevermind... whew... figured it out.

Mark threads as solved and update first post with whats happening, so one doesnt waste time like i did.
No need to double post for that.

How to unroot and relock recovery? (fully revert to stock)

I have unlocked and rooted Nexus 5x and would like to revert back to stock + relock bootloader.
What is the easiest and safest way to achieve this?

download fastboot and fastboot drivers then download latest factory image from here https://developers.google.com/android/images?hl=en and unzip it now you should have 6 files but we are gona use only 3 bootloader-bullhead-something.img radio-bullhead-something.img image-bullhead-something.zip now flash bootloader
fastboot flash bootloader bootloader-something.img then fastboot reboot-bootloader then fastboot flash radio-bullhead-something.img and fastboot reboot-bootloader now unzip the other file and cd into it then fastboot flash boot boot.img fastboot flash recovery recovery.img fastboot flash system system.img fastboot flash vendor vendor.img fastboot flash userdata userdata.img and finaly fastboot flash cache cache.img now start your device and if it boots normaly reboot to bootloader again and run fastboot flashing lock (this is gonna wipe all your data so dont set up anything just make sure it boots)

or just run flash-all

Nexus 5X stuck in bootup

Hi,
I have a Nexus 5X that was on the latest 8.1 firmware, and I successfully downgraded to the latest 6.0.1 firmware by unlocking the device and flashing everything separately. Here's what I did
Enable OEM unlock in Developer settings
Reboot to boot loader
fastboot flashing unlock
fastboot flash boot boot.img
fastboot flash bootloader bootloader.img
fastboot reboot-bootloader
fastboot flashing unlock (had to do this cos after rebooting, device is locked again)
fastboot flash radio radio.img
fastboot flash recover recovery.img
fastboot flash system system.img
fastboot flash vendor vendor.img
fastboot reboot
After this, I get the "Your device is corrupt. It can't be trusted and may not work properly" boot up message, but continue anyway, after which the device boots up and I set up the new device as per normal.
Then, I tried to flash TWRP in order to install Magisk. It is during this step that the device is stuck in the bootup process with the 4 colorful circles. Here's what I did
Reboot to boot loader
fastboot flash recover twrp-recovery.img
Reboot to recovery to check TWRP has been installed (it has)
Reboot to system (stuck in bootup!)
How can I get it to boot up again?

I ended up waiting for the battery to drain and the device to shutdown.
