What base/pagesize parameters to use for mkbootimg? - Galaxy Tab 2 Q&A, Help & Troubleshooting

I want to mod my stock boot.img for init.d support, but I'm not sure what "base" and "pagesize" parameters to use with mkbootimg. Can anyone help me out?

Thanks! So, these settings are specific to the kernel. I see that for CM kernel, I would use:
BOARD_KERNEL_PAGESIZE := 4096
BOARD_KERNEL_BASE := 0x40000000
I was also trying to modify the stock boot.img for my device (p3110) and I came across a tool called "unmkbootimg" found here:
http://forum.xda-developers.com/showthread.php?t=1877807
When I use this new tool to extract the stock boot.img, I get this:
mkbootimg --kernel kernel.gz --ramdisk initramfs.cpio.gz --base 0x80000000 --cmdline 'console=ttyO2,115200n8 mem=1024M androidboot.console=ttyO2 vram=20M omapfb.vram=0:16M androidboot.carrier=wifi' -o new_boot.img
When I use the tool to extract the CM10 boot.img, I get this:
mkbootimg --kernel kernel.gz --ramdisk initramfs.cpio.gz --base 0x40000000 --pagesize 4096 -o new_boot.img
cool.

[HELP] 4.2.2 correct address

Hi!
What is the correct line to generate a kernel for 4.2.2?
mkbootimg --kernel zImage --ramdisk ramdisk.gz --base 0x80600000 --pagesize 2048 --ramdiskaddr 0x81С08100 --cmdline cmdline.txt -o boot-new_4_2_2.img - bootloop
mkbootimg --kernel zImage --ramdisk ramdisk.gz --base 0x80600000 --pagesize 2048 --ramdiskaddr 0x80C08100 --cmdline cmdline.txt -o boot-new_4_2_2.img - bootloop
or
mkbootimg --kernel zImage --ramdisk ramdisk.gz --base 0x80600000 --pagesize 2048 --ramdiskaddr 0x80C08000 --cmdline cmdline.txt -o boot-new_4_2_2.img

This should help you see the offset address from the ramdisk. Or point you in the right direction.

Unpack and repack boot.img (Help needed, stuck at booting)

I've been trying for like hours to unpack and repack a boot.img.
I never made this before, I was reading much (actually too much) on the internet on how getting this done.
So... I downloaded some tools for unpacking and repacking the boot.img and followed this tutorial:
http://whiteboard.ping.se/Android/Unmkbootimg
and I suceeded. But when I repack it (WITHOUT modifying ANYTHING), and try to flash the "new" boot.img to the phone, the phone turns on and then shows up on the upper left corner of the screen "KERNEL IS NOT SEANDROID ENFORCING" and stays there. It goes no further. I simply unpacked it and then repacked it (to see if I made the whole process right, before screwing anything up).
I saw something curious: The original boot.img is 14.3MB and the new boot.img only 14.0MB. Is there anything that got lost in the process? Remember that I set all the "adresses" to the files right.
Unpacking command:
Code:

[email protected]:~/Área de Trabalho/UNPACKTOOLS$
I also tried without those adresses. Without luck.
The phone is a (Samsung J1) "J120H" with Android 5.1.1.
And the boot image I obtained by downloading the stock rom and unpacking ONLY the "boot.img". Remember: When I flash this file alone, IT WORKS. When I unpack and repack it, it stops working.
Here are the tools which came and my boot.img (unmodified from stock rom): https://volafile.io/get/overPkOTw66W/ToolsWithBootImg.zip
If anyone can direct me in the right way, I would be very happy.
Or maybe even modify the boot.img for me, set "secure=0" and repack it. Because my main goal is to root the device.
Thanks.
Anyone?

Not exactly answer to your problem. I tried same thing - just unpacking and repacking It stuck at boot saying 'fastboot reason fall through normal boot mode'
This SO: has similar post : http://stackoverflow.com/questions/27889621/error-with-repacking-boot-img-android
I suspect the base address is wrong in all three cases.
May be if you are searching for solution we can search together

Changing --base 0x0 to --base 0x10008000 does the trick. You may need to play around with your device PHYS_OFFSET. For more read this https://lyncd.com/2011/03/android-kernel-mkbootimg-base/

[Q] boot.img creation dt.img problem

Recently I tried to build kernel from source. All went pretty good, kernel works but only with old pre-build dt.img which comes with the boot.img which I use as a base.
To collect dt.img i used compiled from source
gitlab.com/Thecrazyskull/oneplus2/raw/652861ab053df83c61e4c8d4807a52598703a5e6/dtbTool/dtbtool.c
Code:
./dtbTool -s 4096 -o boot/dt.img -p kernel-out/scripts/dtc/ kernel-out/arch/arm64/boot/dts/
or mkqcdtbootimg(allow to specify dtb dir) from sony xperia
To make image I use github.com/luckasfb/mkbootimg-worked-mtk
Code:
./mkbootimg --kernel Image --ramdisk boot.img-ramdisk.gz --cmdline "console=ttyHSL0,115200,n8 androidboot.console=ttyHSL0 androidboot.hardware=qcom user_debug=31 msm_rtb.filter=0x37 ehci-hcd.park=3 lpm_levels.sleep_disabled=1 boot_cpus=0-5 ramoops_memreserve=2M androidboot.selinux=permissive" --base 0 --pagesize 4096 --dt dt.img --ramdisk_offset 01000000 --tags_offset 00000100 -o newboot.img
So, the question, what am I doing wrong?
Use the dtbTool found here https://source.codeaurora.org/quic/kernel/skales/tree/
git clone git://codeaurora.org/quic/kernel/skales

I use it in my kernel build helper and it works.
