Could any of you guys (with root) upload a boot.img of this device?
You should be able to see where boot is mapped to if you look under /cache/ - there should be a recovery folder.
Then use following commands to dump the image:
Code:
su
dd if=/dev/block/bootpartitionname of=/sdcard/boot.img
Thanks in advance,
Tim
EDIT: smaskell has now done this here
Any help you could offer would be greatly appreciated

I couldn't find a thread on this. If there is one and I just missed it, please direct me that way and I apologize for the duplicate.
I hacked the .config file (kernel), compiled it, tested it in fastboot's boot mode (from the bootloader) and then flashed it to the phone with the instructions on this site:
credentiality2.blogspot.com/2010/08/nexus-one-htc-passion-compile-and-flash.html
It works and is wonderful, but I would love to find a way to create a boot.img file with the kernel I've hacked. Do any of you have any insight or know where I can look for more info.?
Do any of you know how to create the boot.img-ramdisk.gz file? I know how to put that with my hacked boot.img-kernel file and create a boot.img file that way.
Any help is much appreciated.
Fixed!
I figured out the problem was I couldn't the boot.img file from my Android 2.2 phone because the read-write permissions did not allow me to do the adb pull command. Now, I've pulled that boot.img file and can unpack and repack it with my hacked kernel using the directions on the website I originally referenced.
I used this command to change the permissions so I could pull the boot.img file:
#mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
Hi,
I have rooted my HTC Dream successfully. I have flashed in CyanogenMod ROM.
Now I have downloaded Android Kernel and rebuilt it. Now I have the zImage which is the kernel image. Now how do I use this new image? I guess must modify the boot.img to use this new kernel image.
Any idea how can I do this? I tried using "fastboot flash:raw boot <kernel directory> <ramdisk directory>"
For <ramdisk directory> I point to the one in the android-sdk. But after flashing it stuck in the "G1 T Mobile" screen and doesn't proceed. Not sure how to resolve.
Thanks In Advance,
Perumal
I downloaded the boot.img file, split it into boot.img-kernel and boot.img-ramdisk.gz. Then, renamed my newly-compiled kernel's "zImage" file as "boot.img-kernel" and zipped them back up into boot.img. Then, I flashed it to the phone with fastboot. All of the directions are on this website:
credentiality2.blogspot.com/2010/08/nexus-one-htc-passion-compile-and-flash.html
It was written for HTC Passion / Nexus One, so you may want to pull your existing boot.img file first in case it doesn't work on the HTC Dream and you need to go back to where you started. I found this tutorial helpful for that.
credentiality2.blogspot.com/2010/08/extract-bootimg-from-android-phone.html
You probably need to change your permissions to push and pull the boot.img file. I would do that on my computer (with it tethered to the phone), using the following commands in a terminal window:
$ adb shell
$ su
# mount -o remount,rw /dev
Hi, I'm from the samsung galaxy tab 7 plus and I'm trying to build a rom for our tab. But i need to extract the boot.img from my tablet. So I came here to ask you guys how you extracted your boot.img to build your custom roms. I figured i'd come here for help since our devices are very similar in terms of hardware.
easiest way is to download your stock rom (see http://forum.xda-developers.com/showthread.php?t=1367478) and then untar it -- the boot.img should be there
Use terminal emulator
This from tab 7,7 partition table..
to extract kernel(boot.img) you can type this
Code:
dd if=/dev/block/mmcblk0p5 of=/sdcard/boot.img bs=4096
to extract recovery, type this
Code:
dd if=/dev/block/mmcblk0p6 of=/sdcard/recovery.img bs=4096
both of file will extract to sdcard, you can replace destination folder with yours..
if you want to repack boot.img or recovery.img dont use this method, you need image from odin file..
Like post above before me

oh...i found the problem is that i only can use adb in recovery mode. But everytime i reboot it, all changes i made will be erased automatically due to the limited storage i think. So, i created the folder and it just being erased.
i know it.
1. Turn on device
2. Create a folder
3. Run adb
4. Write commands.
Must write a lot of text after the second command. So fff installed. If you reboot kf after this, can see yellow triangle.
thank you so much Deat7
hi guys
as you all know that some of the devices (i9300i) are hard bricked by flashing indian 4.4.4 so to unbrick we need a debrick.img which you guys can help us get by flashing this file https://copy.com/1ggUuyIqHUrF it will create a debrick.img into your sd card which you can upload and share
source http://forum.xda-developers.com/show....php?t=2439367
OR
Use this procedure to create the image
Enable USB Debugging.
Open cmd and navigate to your adb folder.
Run adb shell
Now type 'SU' to enable superuser, your may have to grant access to ADB from a popup screen of your phone's superuser app
next copy and paste the following code and change the phone model to your phone i.e. dd if=/dev/block/mmcblk0 of=/sdcard/debrickI710-16GB.img bs=1M count=128
dd if=/dev/block/mmcblk0 of=/sdcard/debrick[phonemodel-memorysize].img bs=1M count=128
6. Now type Exit on cmd and then use following the command to copy this image to your adb folder
adb pull /sdcard/debrick[phonemodel-memorysize].img
7. upload the image and share its link here.
[B]It will just take few minutes further you can compress the file (zip or rar) to reduce its size so that it can be upload easily.[/B]
Thanks in advance

Hi, I've used your CWM script but it doesn't have created the ZIP file with the debrick image.
I've searched it on all memories (also the system folder) but nothing. I've a GTI9301I ITV Firmware UANI1
I've tried also the adb shell and when i type adb pull /sdcard/debrick[phonemodel-memorysize].img it show me no devices (but it's enabled and the phone receive correctly commands)
Could someone who is running VNS-L21C432B380 upload his/her backup of cust.img and version.img?
Like so using ADB shell:
Code:
dd if=/dev/block/platform/hi_mci.0/by-name/version bs=8M of=/sdcard/version.ext4.img
