osm0sis' Odds and Ends -- Misc./Batch Tools, Flashable Zips, Scripts, etc.

General Information

In a nutshell, I just wanted a single thread to gather links to some of my other, larger projects, but also serve as a spot I could put some smaller scripts and zips I've created that I don't think merit their own separate threads. This is partially for my own sanity and will hopefully make it easier for others to find some things as well. A lot of the stuff here was developed with the GN, N4, N5, N7s or N5X, OP5/T, OP6/T, OP7Pro/T, OP8Pro/T or OP9Pro, or P8Pro (my devices) and Windows in mind, but could generally be applicable to most devices either out-of-the-box or with some slight modification. If you see something that inspires you, go ahead and mod it, just let me know and give me some credit somewhere. If anyone would like to know the specifics of what's in a particular script that I haven't already linked to more information on, just let me know and I'll post that in here as well.

Note: Older zips with a "cwm-" prefix are NOT only for the now-defunct ClockworkMod Recovery, the prefix was used to denote a flashable zip before I adopted Chainfire's "UPDATE-" prefix. Please use a currently maintained recovery, like TWRP, for all zips to ensure the best compatibility/results.

Misc./Batch Tools

AnyKernel3 (many devices) - link

AnyKernel was a simple template for an update.zip that could apply any kernel to any ROM, regardless of ramdisk to reduce the chance of any issues arising from the custom kernel pairing. The drawback to this is that some kernels require modifications to the ramdisk to enable/set up kernel features, and in the old AnyKernel format there was no way to do this. AnyKernel3 pushes the format even further by allowing kernel developers to modify the underlying ramdisk for kernel feature support easily using a number of included command methods along with properties and variables to customize the install experience.

APK-Patcher (many devices) - link

A proof-of-concept, simplifies APK modification to make it easier for modification creators to keep creating. Using JesusFreke's brilliant bak/smali and iBotPeaches' excellent apktool, modified to run on-device along with the various binaries required, allows on-the-fly APK modifications to be applied via recovery, to whatever ROM APK is present, taking the constant update burden off of the modification creator. The zip is smart and automated, using the APK name to run all the various parts involved for complicated patches and is extensible to any number of APKs in a single zip.

Android Image Kitchen (many devices) - link

A collection of Windows/Android ports of the necessary Linux utilities for Android image (kernel+recovery) mod work, and my own automation script to unpack, edit and repack the ramdisk. Other guides/scripts exist but none of them are universal for target device, compression and/or developed for Windows/Android. Now also Linux builds to bring my improved featureset back to where it came from, recently extended to macOS as well. Has been extremely useful for me in my messing around with kernel ramdisks.

ADB Screenshot (many devices) - attached

Take screenshots while in recovery. Useful for development of recovery apps or error reporting. Original method had lots of different threads around with the general method for various devices but I figured out a couple tricks required for getting it working on the Galaxy Nexus and then automated the process. Tested and confirmed working with both pixel formats of CWM and TWRP. More information in this GN Q&A FFmpeg thread. New method uses fb2png and should work on all ARM devices.

ADBsync sdcard Backup (many devices) - attached

Backs up the entire sdcard so that you can have a complete snapshot of your device when you make periodic backups, and be able to restore things exactly as they were. Automates the sync process of Renate NST's great adbsync utility which makes only newer files get pulled, significantly decreasing backup time for the sdcard compared to "adb pull". Original version posted in the old adbsync thread. Defaults for devices with /data/media/ internal sdcards (Nexus devices, etc.), but is easily customizable to backup other mountpoints or backup via ADB over WiFI.

Flashable Script Zips

TWRP A/B Retention Module script (many devices) - link

We need an interoperable root ecosystem again. A/B and system-as-root were a big setback to the root community in this respect. To help alleviate this issue, this atypical Magisk script zip "module" will keep TWRP installed to both slots when flashed from Magisk Manager after an A/B OTA has installed in the background, but before you use Manager to install Magisk to inactive slot.

Nexus BootUnlocker script (GN, N4, N5, N7 '13, N10) - attached

I don't know about everyone else but sometimes I find I've rebooted into the bootloader only to realize I've forgotten to unlock it in segv11's excellent BootUnlocker App beforehand. Well, I decided to make a BootUnlocker Script for my Galaxy Nexus so I could just boot to recovery quickly, unlock, then adb reboot-bootloader (or use my Reboot To Bootloader script below) to get back without having to fully boot the OS to make the change. Also extremely useful in the case you aren't able to boot. As with the app there is no data loss like there would be with fastboot, allowing you to relock for safety. Originally posted in the GN EDIFY Scripting thread. Modified for the newer Nexus devices and combined into a single Nexus BootUnlocker zip with tamperbit reset support added using information from the BootUnlocker App Dev thread. For newer devices using Factory Reset Protection (N6 and later), the BootUnlocker Script can't directly toggle the lockstate due to new security tokens, but it does now toggle the ability to use "fastboot oem unlock" without needing a booted device.

N7 BootUnlocker script (N7 '12) [creation guide] - link

The Nexus 7 2012 is a special case. Per-device encryption of an entire partition makes it impossible to support the N7 '12 in a simple root app, or flashable zip as above, however using my guide and included script you can now create a working BootUnlocker Script Zip for your specific device. As with the above scripts there is no data loss like there would be with fastboot, allowing you to relock for safety.

sdcard Fix Permissions script (many devices) - attached

A little flashable zip script to fix ownership and permissions of files and directories on the sdcard to what they would be if Android OS had put them there itself, since some apps can't access pushed files that have root.root as owner/group. This is useful when restoring to your sdcard backup, as with my ADBsync sdcard Backup batch script above, since generally, pushed files get root.root from adb shell and higher permissions than usual. Also a solution for a bug where sdcard files get lower permissions somehow, resulting in similar access problems. Currently written for devices with /data/media/ internal sdcards (Nexus devices, etc.), but could easily be modified for other mountpoints. No longer required on Oreo since it fixes these itself at boot.

Recovery SLAM script (many devices) - link

Recovery "Simple Legacy Auto-Mount" (SLAM!) is for devices that have been updated to SAR, but there are older zips that break in TWRP because they rely on the mounts occuring a certain way, especially during a ROM OTA. Recovery SLAM mounts them more as the zips would expect, generally allowing them to proceed. Most useful for premounting /system before a legacy zip with my FlashAfterUpdate addon.d script.

SUmount script (many devices) - attached

Another tool for the toolkit of anyone using Chainfire's SuperSU or topjohnwu's Magisk systemless root, this simple flashable zip script toggles the mounting of the su.img, magisk.img and magisk_merge.img while in recovery to allow easier access to the /su, /magisk and /magisk_merge filesystems, simplifying manipulating it via ADB shell, AROMA Filemanager or TWRP's terminal/file manager. Especially useful to anyone who uses su.d/post-fs-data.d scripts or can't boot due to some issue with a user addition in /su/su.d, /su/bin or a Magisk module.

unSU script (many devices) - link

While experimenting with Chainfire's brilliant SuperSU systemless root, I discovered that uninstalling the older style system-modifying root through his app (<2.60) didn't restore all of the modified system files correctly, so I wrote this script to do so and aid in people wanting to unroot from recovery. Expanded to support uninstallation of Koush's SuperUser, phh's Superuser, SuperSU Systemless (su.img and BINDSBIN), Magisk, LineageOS addonsu and custom ROM su binaries.

Adreno Systemless Installer script (N5, N6, N7 '13) - link

For use with Qualcomm's official updated preview GPU drivers packages for Adreno 3xx/4xx-powered Nexus stock images. This is a different frontend to take whatever device zip from Qualcomm is in the same directory as it (also searching /sdcard), then unpack and install it as a Magisk module or into the SuperSU systemless root /su filesystem, instead of the usual /system.

Kernel MultiROM Injector script (many devices) - attached

Intended for use in Chainfire's excellent FlashFire app to automate re-injecting the current boot image ramdisk with Tasssadar's brilliant MultiROM's trampoline bootmenu; this avoids having to do this as an extra step in MR-TWRP following an OTA, ROM Delta or SuperSU update. Should work for all EMMC devices with MultiROM installed.

GN PIT Editor script (GN) - link

Dumps and alters the Galaxy Nexus' Partition Information Table (PIT) to reclaim unneeded space from the /cache partition and add it to /system to allow for larger ROMs and GApps packages to make continued support for Lollipop+ easier. The resulting file is byte-for-byte identical to those created by external tools like PIT Magic, so that it may be flashed back to the device in Odin Mode to complete the repartitioning.

Kernel Emergency Reset script (many devices) - link

Basically a go-to cure-all for custom kernel users experiencing issues after an upgrade due to old settings left over in a kernel control app (eg. franco.Kernel updater, Trickster, etc.), or problematic init.d/userinit.d scripts. It's also useful if you just want to make sure you're running clean defaults without conflicts.

Reboot To Bootloader script (all devices) - attached

Those who preferred using CWM may have noticed a couple of things missing that the other popular custom recovery, TWRP, has built-in. One of these is a file explorer/manager, which is answered by amarullz' brilliant AROMA Filemanager. Another thing I found myself wanting was a way to reboot back to the bootloader once I'm in recovery, so I created this very very simple flashable zip script. (No longer required on CWM >=6.0.3.5). Note: Once in the bootloader, "Start" will boot you back to recovery. Not sure why, but it's not a big deal, just reboot normally from recovery at that point.

Flashable Installer Zips

Flashlt Installer (many devices) - attached

Installs my Flashlt script to allow easy flash and dump of boot, recovery and radio/modem (possibly others) EMMC or MTD partitions while booted, and trimming of null characters from files. Also installs a script zip that makes flashing boot.img (kernel), recovery.img, and radio.img/modem.img (baseband) files via recovery simple. It aims to save the average user the hassle of repacking their own image zip, or using the command-line or fastboot to flash it. Place an appropriately named file in the same directory as the zip and flash away! Should work on all devices with normal partition naming ("boot", "recovery" and "radio" or "modem") which accept Android standards-compliant images (including a/b slot devices like Pixel). Extremely handy when used with amarullz' brilliant AROMA Filemanager, and/or my Android Image Kitchen: Mobile Edition (linked above).

Busybox Installer (all devices) - attached

A byproduct of building my own static busybox compiles in all Android architectures for my AIK-mobile package, I figured I might as well offer them up separately as well since there weren't any providers making Android x64 builds when I was researching. Detects device (ARM/64, x86/_64, MIPS/64) to install the busybox binary, cleans up symlinks from any previous install and generates new ones. Detects and supports SuperSU/Magisk systemless installs. Please read the release post about applet inclusion and special features.

nano Terminal Editor Installer (many devices) - attached

An installer to push my own static Android arm/arm64 build of the nano editor and required files to /system/xbin and /system/etc/terminfo, with a wrapper adding a --term option to try terminfo profiles more easily. Detects and supports SuperSU/Magisk systemless installs. Can then be used from Terminal while booted. When flashed in recovery also allows temporary recovery use by pushing a script to /sbin/nano with the required setup, so you can trigger it from adb shell or TWRP Terminal. Makes it extremely easy and worry-free to tweak and mod on the go, knowing you can edit the faulty build.prop or startup script if something goes wrong.

adb + fastboot Installer (many devices) - attached

Marshmallow removed adb from the /system/bin directory. For those wanting this functionality back, here's an installer to push static compiles of adb and fastboot to /system/xbin, with a wrapper to point adb to the correct HOME directory and set TMPDIR for compatibility. Detects and supports SuperSU/Magisk systemless installs. Can then be used from Terminal while booted.

Nexus Media Installer (many devices) - attached

Custom ROMs usually don't include Google ringtones/notifications/system sounds and bootanimation, instead including numerous terrible sounds and often less-than-desirable visuals. This installs the media from old Nexus devices systemlessly (SuperSU and Magisk supported), or to system with an addon.d script to survive a ROM update or dirty flash, and using the zip name (also reading from /data/.nexusmedia) to allow user choice.

mtd-utils Installer (many devices) - attached

mtd-utils (flash_erase, nanddump, nandwrite) are necessary for mod work on a number of Android devices using mtd/char devices instead of the more standard emmc/block devices, and where the busybox versions have been less reliable in the past (especially where it doesn't include flash_erase), using the official suite is preferable. The older ARM builds available on XDA were about a decade old, so I worked out how to configure and cross-compile from the latest source. Detects and supports SuperSU/Magisk systemless installs. Can then be used from Terminal while booted

Zip + ZipSigner Installer (many devices) - attached

Signing zips and APKs on-device has always been a tricky proposition due to memory requirements of the old SignApk.jar, running a jar on an Android device, and other complications for script-based zips. Android has always been missing a zip binary (for unzip see my Busybox Installer). ZipAlign is also handy if you do APK work. To remedy this once and for all, here's an installer to push my dexed version of topjohnwu's brilliant zipsigner.jar and static arm/arm64 compiles of zip and zipalign to /system/xbin, with a wrapper to run zipsigner with Android's dalvikvm. Detects and supports SuperSU/Magisk systemless installs. Can then be used from Terminal while booted.

odex Script Installer (all devices) - attached

Based on the great work and binaries from this thread, a simple installer to push my odex script along with the required dexopt-wrapper and zip binaries to /system/xbin and set the appropriate permissions. Automates the procedure to odex any apk or jar from the commandline to potentially improve performance. Dalvik runtime (KitKat and below) only. Also uses cut from busybox.

N5X/6P BLOD Workaround Injector (N5X, N6P) - link

When, unfortunately, my Nexus 5X was recently stricken with the abominable Bootloop of Death, I looked into the well-publicized workaround and turns out it was all contained in the ramdisk and cmdline of a Android image. This is the perfect application of AnyKernel2, so I made an AK2 add-on zip to patch both the current boot and recovery partitions with all the current workarounds to help others afflicted by this issue to hopefully regain their data/device as easily as possible. Linked is the Nexus 5X thread, the Nexus 6P thread may be found here.

N7'13 TWRP flo2flox Injector (N7 '13) - link

The Nexus 7 2013 (flo) has seen a bit of a resurgence with official Lineage 18.1 support repartitioned as "flox". Since official TWRP is still automatically being built only for flo and this isn't compatible with flox, and the minor changes required for flox support were a great application of AnyKernel3, this zip automates the patching process so making official TWRP from flo2flox is easy for all going forward.

GN Synapse Support Injector (GN) - link

This AK2 kernel add-on for the Galaxy Nexus injects support for the Synapse tweaking app into the current boot partition ramdisk, including all the Synapse interfaces for the GN I've maintained since the Franco Kernel and DirtyV Kernel days.

GN Recovery Color Correction Injector (GN) - link

The aging screen on the Galaxy Nexus was looking pretty rough in recovery until I discovered the recently added new OMAP kernel color correction was also present in the most recent TWRP recovery versions. So this add-on zip uses AK2 to patch the current recovery partition ramdisk to add the command to reduce that green/yellow SAMOLED nastiness.

Kernel init.d Support Injector (many devices) - attached

An experimental proof-of-concept. Following from great ideas by Captain_Throwback in my AnyKernel2 thread and using script from my Flashlt script above, this AK2 zip will inject basic init.d bootscript support into any kernel ramdisk on any emmc device with normal partition naming and using the Android bootable image standard, without having to bloat a ramdisk using a busybox binary. This zip is also signed, so could potentially be used with non-Nexus stock recovery on a locked bootloader.

CMSetup Fix for GApps Installer (many devices) - attached

Installs a su.d script fix to work around the CyanogenMod/LineageOS 13 ROM issue of a broken Quick Settings pull-down when CMSetupWizard is removed as part of a GApps installation. Removing CMSetupWizard is useful because it allows Google's SetupWizard to grant apps default permissions, so the workaround automatically executes the only required command at the appropriate time following first boot. Requires a SuperSU/Magisk installation (for su.d/post-fs-data.d support). Flash after the SuperSU/Magisk zip and your GApps.

Dev Team init.d Pack Installer (all devices) [see "950iosettings, etc." below] - link

A simple installer I wrote to create the /system/etc/init.d/ directory, extract the latest init.d scripts as published by the "Franco's Dev Team" tuning collective (of which I was a member), then set correct owner, group and permissions to the entire init.d directory. If you are a developer and would like to include these tunables/scripts in your kernel or ROM please provide credit. A lot of time and effort has gone into this project and that's all we ask.
