[Fix] Mobile Hotspot Hack Reposted for OTA 4.24.651.1

I didn't write this hack, but it appears to work with the new stock GB update.
I did edit the script and zip archive so it wouldn't need any external exe's or libs to apply. Just copy the newest framework.jar file to the script directory and run the HackHotspot.bat file. Then simply run these ADB commands from a dos window.
------
adb shell
mount /system
exit
adb push framework.jar /system/framework.jar
-------
clear Dalvik and fix permissions if desired
Reboot Phone
Done!

Much appreciated but way over my head (I've never done anything with ADB). Any chance of getting this, and the USB debugging notification fix, in a flashable form?

The debug fix is the one that doesn't display the statusbar icon when connected?
I'll see what I can do for ya

[SCRIPTS] Unpack / repack MT65xx/MT83xx boot.img, recovery.img or logo.bin

If you are looking for a way to easily unpack / repack boot.img, recovery.img or logo.bin from your MediaTek device (all except Android One devices), don't look any further. Here you can find my own Perl scripts.
Scripts were first based on the ones available on Android-DLS WiKi, but are now highly modified in order to work with specific MTK boot and recovery images. The scripts fully work with every image from all known MediaTek SoC:
MT6516
MT65x3 (MT6513 and MT6573)
MT65x5 (MT6515 and MT6575)
MT6577
MT65x2 (MT6572, MT6582 and MT6592)
MT6589
MT83xx (MT8377 and MT8389)
MT6595
The most up to date version of the scripts is always available at my public github repository: bgcngm/mtk-tools. Scripts require Perl v5.14+ to be installed and were fully tested under Ubuntu 12.04 as well as Windows 7 x64 (using Cygwin).
Please don't just leech the files and go away. You can easily say thanks just by pressing "Thanks" button.
Unpack script usage:
Code:
Usage: unpack-MTK.pl <infile> [COMMAND ...]
Unpacks MediaTek boot, recovery or logo images
Optional COMMANDs for boot or recovery images are:
-info_only
Display file information only
(useful to check image information without unpacking)
-kernel_only [--debug]
Extract kernel only
-ramdisk_only [--debug]
Extract ramdisk only
(optional argument '--debug' can additionally be used to provide useful
information for debugging purposes, even while unpacking both kernel
and ramdisk)
Optional COMMANDs for logo images are:
-force_logo_res <width> <height>
Forces file to be unpacked by specifying image resolution (in pixels)
(only useful when no zlib compressed images are found)
-invert_logo_res
Invert image resolution (width <-> height)
(may be useful when extracted images appear to be broken)
Repack script usage:
Code:
Usage: repack-MTK.pl <COMMAND ...> <outfile>
Repacks MediaTek boot, recovery or logo images
COMMANDs for boot or recovery images are:
-boot [--debug] <kernel> <ramdisk-directory>
Repacks boot image
-recovery [--debug] <kernel> <ramdisk-directory>
Repacks recovery image
(optional argument '--debug' can additionally be used to provide useful
information for debugging purposes, while repacking)
COMMANDs for logo images are:
-logo [--no_compression] <logo-directory>
Repacks logo image
(optional argument '--no_compression' can be used to repack logo images
without compression)

Editing .rgb565 raw files
There may be other ways for doing this, but here's a short info that will help you to edit .rgb656 raw files found inside MTK logo images.
Download and install Paint.NET
Download the attached plugin and copy the RGB565.dll file to the folder: "C:\Program Files\Paint.Net\FileTypes"
Open the .rgb565 file and enter image height and width
Information:
The plugin will allow read and write support to the RGB565 or RAW565 format. This format is used by the Android platform for the initial boot screen of the device. It will also allow you to open a BMP, PNG, JPG or other image and save it as a RGB565 file.
RGB565 is simply the raw pixel data of a bitmap file. It does not contain any header information and does not contain the dimensions of the image. The only thing that is known is the total number of pixels. When opening a .rgb565 file, the user must specify the height and width of the image, which is the resolution of your device's screen.
Just as an example, for a device with a 540 x 960 screen, the .rgb565 file for that device will have 518400 pixels. The size of the file in bytes will be twice the number of pixels, i.e. 1036800 bytes.

hello,
i tried ur script and works with MT6573 but i need some help.
How to repack?
The syntax u posted looks little jumbled and i need a example on unpack and repacking from u
Burned from my laser torch using pencil cells

Simple... let's say you unpack a boot.img:
Code:
unpack-MT65xx.pl boot.img
This extracts the kernel (it will be named boot.img-kernel.img) and the ramdisk folder (it will be named boot.img-ramdisk).
In order to repack, you should run:
Code:
repack-MT65xx.pl boot.img-kernel.img boot.img-ramdisk new-boot.img
If you are repacking a recovery.img, then it should be:
Code:
repack-MT65xx.pl -recovery recovery.img-kernel.img recovery.img-ramdisk new-recovery.img

I m getting "can't exec "mkbootimg" : No such file or directory at ./repack-Mt65xx.pl line 66" error
Now?
Edit: Solved the error

How did u solve?

Probably it was just a matter of setting the proper permissions.

I have only used the scripts under Ubuntu, so never tested it on a Windows environment.
Are you sure that you have Perl correctly installed?

tried with ubuntu works.
Thanks!!!

Works in windows with cygwin too with some minor tweaking...
change the repack script line 66, mkbootimg to ./mkbootimg.exe & replace mkbootimg with this windows version... i think it should work with any mkbootimg.exe windows version too...
ignore the unpack scripts error though, it works fine actually in cygwin...

If someone gets the error:
can't exec "mkbootimg" : No such file or directory at ./repack-Mt65xx.pl line 66
Follow this:
In Ubuntu:
copy the 'mkbootimg' file and paste it in your /bin folder.
A command like this in the terminal will do the work:
Code:
sudo cp /path/to/unpack-repack-scripts/mkbootimg /bin
(enter your password, when it asks)
In windows(using cygwin):
Edit:
Use the OP to download latest script.

give the binary execute permission, and move it to somewhere in the path:
sudo chmod a+x mkbootimg
sudo mv mkbootimg /bin

@OP
Real Gr8 job
For those people facing problems regarding the mkbootimg ,
Just that you need that binary compiled for your system
Here is for OS X (tested on 10.7.4) attached !
I just compiled form the Source
got from Internet ( lazy to boot that thing in Parallels )
for compiling !!
Source for Windows :
http://www.freeyourandroid.com/guide/extract-edit-repack-boot-img-windows
mkbootimg for OS X, Linux and Windows
Does any one need for Linux ?

Help extracting initramfs from Kernel [SOLVED]

Hi,
My Question is
How do i extract initramfs from a Kernel.bin file ?
the Galaxy S Advance uses Kernel.bin instead of a boot.img
I tried dsixda's kitchen, but it couldn't recognize the file format
I just want to replace a certain binary in the /sbin folder and repack the kernel.
Edit:this phone is kinda different,
it seems that the recovery and kernel partitions are the same

Figured it out
The zImage created after compilation process is actually the same, a kernel binary aka kernel.bin
I just had to rename the zImage to kernel.bin and add md5sum to the kernel.bin and pack it into a tarball to make it flashable via odin.
that can be done like this
Code:
md5sum -t kernel.bin >> kernel.bin
mv kernel.bin kernel.bin.md5
tar -cvf mykernel.tar kernel.bin.md5
As for packing the ramdisk into the kernel.bin
that can be done before compiling by editing the .config file or any config you gonna use
just have to add the path to the ramdisk at CONFIG_INITRAMFS_SOURCE="path to your ramdisk"
There's also a script to unpack the ramdisk from the kernel.bin, i'll attach it here
usage:
place the script at the same location of the kernel.bin
Code:
chmod +x unpack-initramfs.sh
bash unpack-initramfs.sh kernel.bin.md5
OR
/bin/sh unpack-initramfs.sh kernel.bin.md5
Hope this helped Others who were facing the same problem

how to repack it?

Unpack, Modify, Repack and Loki SGS4 Boot Image! (14 Jul 2013)

Here I consolidate the custom tools necessary to unpack, modify, repack and loki your JB 4.2.2 ROM zip boot.img!
These Windows/cygwin tools invoke the djrbliss loki bootloader exploit for your rooted SGS4!
See my Instructional Demo below! Results are tested working on my AT&T SGH-I337 running Liquid Smooth v2.8 (JB 4.2.2) and TWRP Recovery 2.5.0.2.
SGS4 Boot Image Toolset (sgs4-boot-tools.zip): http://www.mediafire.com/?6sp3pp33lxgm3ua
Contents
Executive shell script: modify-boot-sgs4.sh to unpack boot image to kernel and ramdisk, thus enabling user to modify boot image
Perl scripts: unpack-bootimg-sgs4.pl and repack-bootimg-sgs4.pl
mkbootimg.exe (make boot image from kernel and ramdisk)
loki-boot directory with ROM-like directory structure --- contains all files needed to “loki” your boot.img
The loki-boot directory also contains two boot files: boot-ref.img (extracted directly from Liquid Smooth ROM zip) and a modified boot.img (generated using the Instructional Demo further below).
My custom repack-bootimg-sgs4.pl invokes the following command string:
./mkbootimg.exe --cmdline 'androidboot.hardware=qcom user_debug=31 zcache' --base 0x80200000 --kernel boot.img-kernel --ramdisk ramdisk-repack.cpio.gz -o $boot-repack.img
Detail:
--cmdline 'androidboot.hardware=qcom user_debug=31 zcache' (command line tellback from unpack-bootimg-sgs4.pl)
--base 0x80200000 (from Liquid Smooth /proc/config.gz: CONFIG_PHYS_OFFSET=0x80200000)
--kernel $boot.img-kernel (ROM kernel file)
--ramdisk ramdisk-repack.cpio.gz (gzipped cpio of/ramdisk)
-o $boot-repack.img (output file)

Instructional Demo
1. Boot SGS4 to recovery and Nandroid backup existing ROM for peace of mind
2. (One time) Create a cygwin working directory (e.g. ~/cygwin/home/modify-boot-sgs4) and unzip the SGS4 Boot Image Toolset files to it
3. On Windows, extract ROM boot.img (e.g. from Liquid-JB-v2.8-OFFICIAL-jflteatt.zip) and place boot.img in cygwin working directory.
4. Launch cygwin command window in working directory and enter script command:
sh modify-boot-sgs4.sh boot.img (produces ramdisk directory: boot.img-ramdisk/)​
CNTL-C out of shell script and back to cygwin prompt.
5. Edit boot.img-ramdisk/default.prop, set: ro.secure=0 and save and close.
Note: The setting: ro.secure=0 instructs Android to grant root to ADB so user does not have to keep entering “su” at the beginning of each ADB session.​
6. At cygwin terminal enter:
perl repack-bootimg-sgs4.pl boot.img​
This yields boot-repack.img.
Here’s a dump of my cygwin session…

8. Connect SGS4 to your ADB-enabled computer, then
adb push loki-boot.zip /external_sd/Download (or your favorite flash directory)​
9. Boot to recovery and flash loki-boot.zip (takes a few seconds)
10. Reboot system and achieve “pre-rooted” ADB sessions on Liquid Smooth!

BTW here's a nice little app: https://play.google.com/store/apps/details?id=com.siriusapplications.quickboot&hl=en
With Quick Boot, you can reboot to recovery via soft key, which is easier than booting to recovery from cold start.
Blessings. Enjoy!

But my past experience is that most users prefer Windows

I am not sure, but I don't think this will work on a fresh install of Cygwin. When i installed cygwin i selected "all" for packages. The directory structure does not match your script, /bin is not under /usr but in the root of cygwin directory. Also, i checked the installed packages, many are missing, and when i search cygwin.com for the missing, i cant find quite a few. Im new to cygwin, as in this op, but not new to software. i tried several boot.img (4.3) thinking it might be the image, but it was a strech and all failed the same. I dont find the .dll your script is looking for, so the error is correct.
I get this error:

UPDATE: well I went through the cygwin install/update again and after searching for each package you listed, installing everything associated with each package, your scripts WORK. I have unpacked/edited/repacked and loaded. ADB as root......profit
Thanks for this

Thanks

Here I consolidate the custom tools necessary to unpack, modify, repack and loki your JB 4.2.2 ROM zip boot.img!
These Windows/cygwin tools invoke the djrbliss loki bootloader exploit for your rooted SGS4!
See my Instructional Demo below! Results are tested working on my AT&T SGH-I337 running Liquid Smooth v2.8 (JB 4.2.2) and TWRP Recovery 2.5.0.2.
SGS4 Boot Image Toolset (sgs4-boot-tools.zip): http://www.mediafire.com/?6sp3pp33lxgm3ua
Contents
Executive shell script: modify-boot-sgs4.sh to unpack boot image to kernel and ramdisk, thus enabling user to modify boot image
Perl scripts: unpack-bootimg-sgs4.pl and repack-bootimg-sgs4.pl
mkbootimg.exe (make boot image from kernel and ramdisk)
loki-boot directory with ROM-like directory structure --- contains all files needed to “loki” your boot.img
The loki-boot directory also contains two boot files: boot-ref.img (extracted directly from Liquid Smooth ROM zip) and a modified boot.img (generated using the Instructional Demo further below).
My custom repack-bootimg-sgs4.pl invokes the following command string:

If you don’t have cygwin, you can download it here: http://www.cygwin.com/ and install.
Cygwin packages installed on my XP workstation are shown below. You probably don’t need all of them, though I believe many come with the base cygwin.
But you definitely need perl

1. Boot SGS4 to recovery and Nandroid backup existing ROM for peace of mind
2. (One time) Create a cygwin working directory (e.g. ~/cygwin/home/modify-boot-sgs4) and unzip the SGS4 Boot Image Toolset files to it
3. On Windows, extract ROM boot.img (e.g. from Liquid-JB-v2.8-OFFICIAL-jflteatt.zip) and place boot.img in cygwin working directory.
4. Launch cygwin command window in working directory and enter script command:
sh modify-boot-sgs4.sh boot.img (produces ramdisk directory: boot.img-ramdisk/)​
CNTL-C out of shell script and back to cygwin prompt.
5. Edit boot.img-ramdisk/default.prop, set: ro.secure=0 and save and close.
Note: The setting: ro.secure=0 instructs Android to grant root to ADB so user does not have to keep entering “su” at the beginning of each ADB session.​
6. At cygwin terminal enter:
perl repack-bootimg-sgs4.pl boot.img​
This yields boot-repack.img.
Here’s a dump of my cygwin session…

8. Connect SGS4 to your ADB-enabled computer, then
adb push loki-boot.zip /external_sd/Download (or your favorite flash directory)​
9. Boot to recovery and flash loki-boot.zip (takes a few seconds)
10. Reboot system and achieve “pre-rooted” ADB sessions on Liquid Smooth!
BTW here's a nice little app: https://play.google.com/store/apps/details?id=com.siriusapplications.quickboot&hl=en
With Quick Boot, you can reboot to recovery via soft key, which is easier than booting to recovery from cold start.
Blessings. Enjoy!

Make sure you install the cpio packages for cygwin.
You can install additional packages by running the setup/install again.
You can also search for cpio via the search bar at the top left when presented with the list of packages.
Hope that helps.

Althoug, now it is telling me Permission Denied, I don't know why, or how to change that in windows 7, but it wasn't giving me any errors before, it just wasn't writing the image

Thank you, you helped me a lot! It worked!
Oh, when I searched for cpio I had to click on "default" ( and select "install" on the windows before clicking "advance"), to install it properly!
A VERY IMPORTANT INFORMATION:
I was trying with Cygwin 64 bit and I had problem repacking it.
I found out mkbootimg only works on Linux 32 bits.
So it is necessary to use Cygwin 32 bit version!
Finally it worked! Thanks a lot!

Yeah, I did that...same result...the problem is with permissions, when I run it in compatibility mode, it tells me permission denied. I'm suspecting
it is a Windows 7 problem, mkbootimg.exe is saying permission denied. I appreciate the answer though. maybe an antivirus program is blocking it or something. my cygwin icon is showing the security essentials icon on it for some reason...i dunno, i'll research it some more and figure it out when I have time, thanks again

I'm doing this on windows 8.1 64bit with cygwin 32 bits. It works. I don't use antivirus, turn off security essentials and other system protecting programs, I'm sure you will do it.

Try it with boot.img from I9505 International , unpack and repack without problem , flash it and phone restart and vibrate constantly.
Any ideas how to fix this problem ?

[Q] "FAILED (remote: dtb not found)" error when flashing image on Xperia Z3

Hello,
I am facing error when flashing image on Xperia Z3. I rooted the device using the link posted on "theunlockr.com"
Now, I am trying to flash a new image on the device. I am extracting the exisiting image from the device, modifying the init.rc file and repacking the image (myboot.img) and then flashing it using fastboot method. This is when it gives me this error.
When I flash the original image that I extracted, it works fine.
I tried following methods: -
1. Changing init.rc file and repacking the .img file and flashing it
When I extract initrd.img (using abootimg), it shows me only these files ( I usually find init.rc file when I extract initrd.img but not in this device, is this expected?): -
- XZ3-AdvStkKernel_DooMLoRD_ramdisk.gz
- logo.rle
- init (linking to sbin/init.sh)
- sbin/bootrec-device
- sbin/ramdisk-recovery-cwm.cpio
- sbin/busybox
- sbin/ramdisk.cpio
- sbin/init.sh
I extracted sbin/ramdisk.cpio file to get the init.rc file using the command: -
cpio -idmv < ramdisk.cpio
After modifying the init.rc file, I repacked the cpio file using the command: -
ls | cpio -ov > ramdisk.cpio
I made sure that none of the extra stuff was not there in the folder before repacking the cpio file.
Now that my ramdisk.cpio file is updated, I created new image using the command: -
find . | cpio -o -H newc | gzip -9 > ../newramdisk.cpio.gz
and created myboot.img using abootimg
When I flashed this image file, I get the "dtb not found" error
2. Second method that I tried was I simply unpacked the boot.img (original image) and repacked it using abootimg in to myboot.img without changing anything.
This also gives the same error.
It looks like there is some issue with the unpacking and repacking of the boot image.
Is there any other way to resolve this issue?

use this instruction and tools, but when you will build your boot.img, use this cmd line
Code:
./mkbootimg --base 0x00000000 --kernel zImage --ramdisk_offset 0x02000000 --tags_offset 0x01E00000 --pagesize 2048 --cmdline "androidboot.hardware=qcom user_debug=31 msm_rtb.filter=0xb7 ehci-hcd.park=3 dwc3.maximum_speed=high dwc3_msm.prop_chg_detect=Y" --ramdisk ramdisk.cpio.gz --dt dt.img -o boot.img
with that instruction all work fine. I've tested many times

Thanks for replying to me.
I just want to modify init.rc file to add few lines. The only file that I see is ramdisk.cpio which contains init.rc. I unpacked it , modified it and repacked ramdisk.cpio. Instead of creating new dt.img, I directly flashed the new img file onto the device and that soft bricked the device. :crying: The steps that you suggested mentions creating a new kernel and creating a new dt.img. Do I need to do that even though I just need to modify just init.rc file?
At this point, I am just trying to unbrick the device using flash tool. I tried cwmrecovery but it did not work so trying flashing tool now. once its done, if it is necessary to create a new dt.img and new zImage using toolchains, I will use that method. Please let me know if you think that is the step that I am missing which caused the device to brick.
Thanks a lot.

UPDATE:
Device is unbricked.!
I just need to root it again and follow the steps that you mentioned. Please confirm if I need new ZImage and dt.img even if I just need to edit init.rc.
Thanks a lot.
