# IMG Patch Tools
Patch image (.img) using sparse Android data image (.dat) in OTA zip with "BlockImageUpdate"
Patch other files (boot.img, firmwares) using patch file (.p) with "ApplyPatchfn"
## Downloads
[Github Release](https://github.com/erfanoabdi/imgpatchtools/releases)
## Requirements
For Building this tool you need :
* zlib
* libbz2
* openssl
It currently supports Linux x86/x64 & MacOS, Not tested on Windows.
## Usage
```
usage: ./BlockImageUpdate
```
args:
- `` = block device (or file) to modify in-place
- `` = transfer list (blob) from OTA/rom zip
- `` = new data stream from OTA/rom zip
- `` = patch stream from OTA/rom zip
```
./ApplyPatchfn [init_sha1(2)] [patch(2)]...
```
- `` = source file from rom zip
- `` = target file (use "-" to patch source file)
- `` = target SHA1 Sum after patching
- `` = file size
- `` = file SHA1 sum
- `` = patch file (.p) from OTA zip
```
usage: ./scriptpatcher.sh
```
args:
- `` = updater-script from OTA zip to patch recovery commands
## Example
for example from updater-script of OTA we have:
```
block_image_update("/dev/block/bootdevice/by-name/system", package_extract_file("system.transfer.list"), "system.new.dat", "system.patch.dat")
apply_patch("EMMC:/dev/block/bootdevice/by-name/boot:33554432:f32a854298814c18b12d56412f6e3a31afc95e42:33554432:0041a4df844d4b14c0085921d84572f48cc79ff4",
"-", 0041a4df844d4b14c0085921d84572f48cc79ff4, 33554432,
f32a854298814c18b12d56412f6e3a31afc95e42,
package_extract_file("patch/boot.img.p"))
```
after getting system.img and boot.img from firmware
This is equals of previous functions on PC with this tools:
```
~$ ./BlockImageUpdate system.img system.transfer.list system.new.dat system.patch.dat
~$ ./ApplyPatchfn boot.img - 0041a4df844d4b14c0085921d84572f48cc79ff4 33554432 f32a854298814c18b12d56412f6e3a31afc95e42
```
scriptpatcher.sh will generate all commands automatically from updater script so run it like:
```
~$ ./scriptpatcher.sh META-INF/com/google/android/updater-script > fullpatch.sh
```
check fullpatch.sh your self, you need to provide all images and files in correct name and patch as mentioned in mount and other commands of fullpatch.sh
