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 (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 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
ZipSigner + Zip 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 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.
Scripts
950iosettings + 875mntsettings + 925vmsettings + 975experimental init.d scripts (all devices) [with Franco's Dev Team] - links
Also available bundled in an installer. The scheduler tunables have already gained a bit of attention/adoption on various devices and kernels, but this is the init.d script I wrote to set the new custom scheduler tunables values as "default" by an independent loop, sleeping in the background and detecting each time the scheduler is changed. There is no effect on idle drain or deep sleep. The settings included are the complete work of the "Franco's Dev Team" (or "Team Franco") tuning collective, of which I was a member. We strove to perfect the scheduler, vm and various other settings for the smoothest and fastest experience available. The collective was: malaroth, osm0sis, joaquinf, The Gingerbread Man, pkgnex, Khrushy, shreddintyres. 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. Lollipop(+) updated versions now also available through the continued excellent work of pkgnex.
999-flashafterupdate.sh addon.d+addon.d-v2 script (many devices) - attached
For ROMs that don't have "Flash After Update" support built into their delta/update process. During an upgrade, this script will flash zips from an sdcard directory, with several options (listed in the script header) for displayed output, after all other addon.d backup/restore actions have completed. This can be used to flash SuperSU and then an AnyKernel2 kernel on LineageOS, for example. Only zips that specifically support addon.d-v2 can be supported on A/B devices. See this how to for instructions for use with A/B devices. Unzip once downloaded and place in /system/addon.d/ with rwxr-xr-x (755) permissions.
98-twrp_ab.sh addon.d-v2 script (many devices) - attached
Allows you to keep TWRP installed in a boot partition through A/B OTAs with Magisk installed by copying the TWRP ramdisk from the current slot to the updated one, before Magisk's addon.d-v2 script patches it. Requires a current Magisk installation since we need the tools and Magisk's the only way to ensure a working addon.d-v2 environment across ROMs at the moment. Unzip once downloaded and place in /system/addon.d/ with rwxr-xr-x (755) permissions.
97-dumpimages.sh addon.d+addon.d-v2 script (many devices) - attached
For ROMs with boot.img, etc. inside an OTA payload.bin or otherwise inaccessible, it dumps the updated chosen partitions before further modifications (TWRP, Magisk, etc.), saving it to /sdcard/Download/boot.img or to/from other customizable locations at the top of the script. Unzip once downloaded and place in /system/addon.d/ with rwxr-xr-x (755) permissions.
00-omnirootfix.sh addon.d-v2 scipt (many devices) - attached
OmniROM appears to include 69-gapps.sh automatically in its /system/addon.d directory despite not shipping with any GApps; when not rooted this doesn't appear to present a problem, but really this is only because the script doesn't have enough permissions to run how it's supposed to since Omni's sepolicy doesn't let addon.d-v2 work correctly. Once Magisk is installed, providing more privileges to the addon.d-v2 update_engine, Omni's 69-gapps.sh would remove important system files during an A/B OTA when no GApps were installed, so this script will simply prevent that for those wanting to run Omni minimally and with root. Remove the .txt extension once downloaded and place in /system/addon.d/ with rwxr-xr-x (755) permissions.
00-resizesystem.sh addon.d script (many devices) - attached
One common solution for aging devices is to resize the /system partition so that it can hold newer, larger ROMs and, of course, GApps packages. On devices where the /system partition has been resized to hold larger GApps packages, but the ROM in use has system.dat format zips with no resizing functionality, the extra space would get lost in a ROM delta flash, breaking things when GApps attempted to restore. This script will resize the system partition to its maximum before the GApps restore occurs on EMMC-based devices with standard partition naming. Remove the .txt extension once downloaded and place in /system/addon.d/ with rwxr-xr-x (755) permissions.
10-extract-lineage-kernel.sh addon.d script (many devices) - attached
Nowadays with systemless root and other boot.img mods out there, it's good to have a backup of your ROM's unmodified boot.img handy in case you want to do a clean flash of your boot partition. Since LineageOS moved their update zips to a /data/data subdirectory that made this harder to get to, I automated the procedure as an addon.d script so that the newest gets extracted on each update. The output directory may be changed by editing the script. Remove the .txt extension once downloaded and place in /system/addon.d/ with rwxr-xr-x (755) permissions.
999-customkernel.sh addon.d script (many devices) - attached
Addon.d is awesome at restoring your GApps, root app, and other things after a ROM Delta, update, or dirty flash, but of course this can leave a lot of stuff out that you'd also have to re-flash (see below for a personal addon.d script you can modify to cover anything else you want to save). This script aims to help remedy the issue for custom kernel users on EMMC-based devices with standard partition naming by dumping the current kernel as part of the addon.d backup process, and then restoring it after the ROM has flashed its included kernel. Remove the .txt extension once downloaded and place in /system/addon.d/ with rwxr-xr-x (755) permissions. This is deprecated by my FlashAfterUpdate addon.d script, above.
logohack.sh (GN) - link
Galaxy Nexus bootloader image replacement hack script. Inspired by bitdomo's brilliant imgdata tool and replicating the functionality of Ezekeel's abandoned, broken paid Logo Me app, this script improves upon the app version by working on all Galaxy Nexus bootloaders and on-the-fly, to allow replacement of the Google logo and lock images within the sbl partition. Remove the .txt extension once downloaded and place in /system/bin/ or /su/bin/ with rwxr-xr-x (755) permissions. It can then be run from the Terminal.
flash_image (many devices) - attached
MTD devices require a little extra finesse when flashing partitions from the command prompt and multiple commands, versus MMC devices, for which we can just use the dd command both ways. I wrote this little script to simplify the process for myself in my MX Box tinkering. It parses /proc/mtd so you only need to enter the partition name. It requires _n0p_'s excellent MTD-Utils compiled for Android, and uses grep and cut from busybox. Remove the .txt extension once downloaded and place in /system/xbin/ with rwxr-xr-x (755) permissions. It can then be run from the Terminal.
getprio (all devices) - attached
Android doesn't allow you to check the priority (or "niceness") of a process with the getpriority command as you would with normal Linux, and busybox doesn't provide this functionality either, so I wrote this reasonably simple script to allow you to check the niceness of a process. Some kernels have been experimenting with increasing the priority of com.android.systemui for smoothness, so this command can be used for testing different levels and whether the renice command set it correctly. Remove the .txt extension once downloaded and place in /system/xbin/ with rwxr-xr-x (755) permissions. It can then be run from Terminal with either the pid (default), class or a class name search string. Uses pidof and pgrep from busybox.
gappsintegrator init.d script (many devices) - link
ROM GApps Auto-Integration of /data/app GApps into /system, complete with libs (unlike Titanium Backup), for Jelly Bean through Marshmallow. It should process things early enough in the boot that afterwards Dalvik will immediately do the cleanup ("Android is upgrading..."), much like following an OTA. An initial GApps installation is one requirement and there are some important notes for support of Lollipop and above. Intended for ROMs with a busybox installation. Can also remove libs from and zipalign the integrated APKs if those binaries are present in the ROM.
lmkwhitelist init.d script (all devices) - link
Users running ROMs or kernels with extremely aggressive custom lowmemorykiller (lmk) driver settings may notice their launcher redrawing frequently. Some kernels/ROMs also include an exclusion for this by making stock (or the included) launcher unkillable, however that still leaves all the 3rd party launchers out there that people use. I wrote this init.d script with a community created list of the most common launchers to make whichever one is installed unkillable. This also has instructions for how to set up init.d scripts. If your launcher isn't included in the list, you can modifiy it by adding the application class name (from the Play Store URL) to the list within quotes, separated by spaces. Also part of the 975experimental Franco's Dev Team init.d script, linked above.
dalvik2cache init.d script (all devices) - link
Bind mounts the dalvik-cache directory to the cache partition. Useful on devices where the cache is sizable and unlikely to be used for OTAs (custom ROM, etc.), and the data partition is not. Every little bit counts!
settingsdump.sh (all devices) - attached
In comparing vm settings from various kernels and ROMs to see what's out there, I wrote this script to generate a list of the values of all the relevant sysfs files and directories. Now expanded to cover cpu and governor as well. Remove the .txt extension once downloaded. To run it, assuming you just put it in /sdcard/, open Terminal Emulator and type: "sh /sdcard/settingsdump.sh" (without quotes). It will output the file to /sdcard/r*-output.txt where * is the revision of the kernel you're running. This makes it easier to compare what's changed between different nightlies, for example.

BootUnlocker app (many devices) [with segv11] - link
With a number of users researching and contributing the bootloader lockbit and tamperbit offsets in threads around xda and to the development thread for seg11's excellent BootUnlocker app, I have begun making beta builds with these new devices added. With hopes of adding any/all that can be, it now supports all the older Nexus devices, OnePlus devices and several others. We are accepting Pull Requests and collaborators for further device/design updates. Check my original revival post for more details.
G-Box Midnight MX2 g18ref ROM, recovery and kernel osmods (MX Box) [with BenniBenassi & relol] - link
I bought one of these unbranded Android TV boxes and was immediately determined to tweak it as much as possible following my work on the Galaxy Nexus. Flashing the official Matricom stock ROM over the generic included one I also discovered the recovery didn't have any A/V output to my old CRT TV. I set out to dump the kernel and recovery images, fix the recovery images and tweak the kernel defaults for the most performance.
Holo Stock Notification Icons for Notification Toggle (many devices) - link
This was likely my first post ever on xda. It is a "Notificon" pack for j4velin's fantastic Notification Toggle App, bringing a seamless stock look to this indespensibly useful app. Also a great way to get back to Settings easily from the notification shade since Android 4.2, and add shutdown/reboot menu functionality to stock/vanilla ROMs.
My GN Kernel Settings + 900colorsettings init.d script (GN) - link
I was being asked a fair amount for my kernel settings over in the GN f.K thread where I helped out, so I posted them up. I also put up an init.d script for setting color values on boot, which can drastically change the outcome on older panels, and at least makes custom values seamless. Instructions for how to set up init.d scripts are included.
Galaxy Nexus Baseband Collection: maguro - i9250 / M420 / SC-04D Radios (GN) [with josteink] - link
Original thread author josteink moved on to other devices and asked me to take over the thread. Lots of great information on the GN radios, posted alphabetically by region and chronologically by the build string date I found embedded in the images. Huge respect and massive thanks to josteink for seeing the need for a baseband thread almost as soon as the Galaxy Nexus was launched, way back in December 2011, and maintaining it diligently.
TK GApps (many devices) [with TKruzze] - link
After helping TKruzze with some of the concept and script work for his famous Paranoid Android Google Apps packages (PA GApps 2.0), we decided to collaborate again for his return to XDA after a much-needed hiatus, with me doing the thread setup and management with DevDB, and a Q&A section so things don't get overwhelming for those trying to follow along. The main thread remains locked and can be subscribed-to for those wanting notification only when there's a new GApps release, and the Q&A functioned as the main discussion thread where people can help each other. Much of the script is the same from PA GApps but TKruzze has added some impressive new features, made many fixes and revamped a large portion of the documentation. I also continued as an adviser and submitted script when needed.
Nexus Louder Audio Improvement Patch (GN, N4, N5, N7 '12, N7 '13) [with Misledz] - link
One of my earliest forays into EDIFY scripting, I wrote the flashable zip install/revert scheme for this great volume boost mod by Misledz. The scripts check to see if the mod is already installed and if so recommends you flash the version-specific revert that goes with it. More on that in the Intelligent EDIFY thread. During install the script also backs up the ROM files it replaces so that you don't need to reflash your whole ROM if something goes wrong, just use the revert to restore the backups. I eventually rewrote this completely in shell script with a Universal install/revert, that detects which files to backup and leaves a list for itself to revert. I also wrote automation batch scripts for Misledz as the "Louder Build Farm" to simplify his work for all the versions of the mod he maintains for various devices, linked in the knowledge base below.

When JB4.3 broke all previous root methods I made this simple frontend script to install rovo89's brilliant Xposed Framework for modding ROMs until they could release a new version themselves. Xposed Framework files and the install.sh used are the work of rovo89 and Tungstwenty; I have only created a recovery flashable zip and shell script to function as an alternative frontend for the framework installation process. Then updated to mimic the APK installation and allow devices with /system write protection like HTC's S-ON to install the framework. (Deprecated as of Xposed 2.5).

avbtool-arm (zip package) - link
AOSP's BootSignature.jar for AVB v1 was relatively simple to run on-device for boot.img modifying flashable zips like SuperSU and AnyKernel2 but avbtool for AVB v2 is written in Python, so that makes things a bit trickier. For experimentation I whipped up a little wrapper script to run avbtool on-device with an actual Python interpreter.

Thanks back to you, everyone! I've learned a hell of a lot about Linux and Android in the year since I got my GN, and I mostly have xda to thank for that, even though I've always been the type to tinker and Google things. Still lots more to learn though! But, at the very least I guess nobody can say I haven't been busy since becoming a RC, huh?
Nice to see all these settings are adopted by others, also the interactive tuneables are used in ak kernel now.

New version of testvalue.sh up. I added the input value to the output.txt file to make it easier to read since it starts at 0. Right now we're trying to work out the equation for the scale of certain cfq and deadline tunables on the GN, which is a bizarre one:
7, 15, 23, 31, 39, 46, 54, 62
Increases by 8s but occasionally (on the 5th jump, though sometimes 6th) it increases by 7.
Edit: Every 3rd increase of 7 occurs on the 6th instead of the 5th.
Edit 2: Stats genius of the group, @pkgnex worked out what the trick was; dropping the decimals once calculated.
So in Excel: y=TRUNC(x*7.8125,0)
:good:
The "why" of the GN tunables working this way, with a value of 125/16 is a very good question. No ideas there, personally. Something to do with the GN having a HZ value of 128 (where on others it's 100 or even 200) I'd assume, but I don't see the direct connection.
This was very handy to know though, because the cfq+deadline source requires the number of jumps (x) to hardcode the values, not the actual desired numbers like you'd expect.
Perfect!!!
Very interesting
Created a getprio script last night for use in /system/xbin as a runnable script to check the niceness of a process. It's up in the 2nd post now. It attempts to make up for Android not having "getpriority", and not displaying the niceness in "top" or "ps" like it would on mainstream Linux.
Code:
usage: getprio [-p] <pid> | -c <class> | -s <search string>
note - class name search will only use the top result
So you can either -p the numeric pid of a process if you know it (this is the default so the -p argument is optional), -c the class name of the process (eg. com.android.systemui), or -s a search string using part of the class name (eg. systemui). If there is more than one result for the search only the top result will be returned so if you are trying something like "-s mms", you'll only see the system mms process and not com.android.mms until you get more specific with "android.mms" or something. It's likely you've got a lower level process if you get the response "Warning: empty class name!" so that's your tip your search was too broad. Naturally, processes must be running in order to return info as well. :good:
Edit: ps -p will display niceness on Android, but it's not ideal if you want it only for a specific process like with getpriority. Thanks boype.
Hi XDA Community!
"This is my first time to post a thread. Please consider me as a junior and don't be ignorant
This is all about rooting all almost devices without using a PC.
I called it...."
DROID Universal Root
or DROID U-ROOT
ROOT can access all features deep down into system, just like you are a Administrator in Windows Computer!
ROOT can give you more benefits like, optimize performance, save more battery life, completely remove unwanted user and system apps, and more!
That's why i created this small package
(ChainsDD has also his package but it's old : http://androidsu.com/superuser/)
REQUIREMENTS:
+ Android 2.3 Gingerbread to 4.2 Jelly Bean (Not yet sure for KitKat)
+ Android Devices with ARM Architecture, not yet available for x86, MIPS, etc.
+ An Android Device with a workable Recovery Mode Console.
(Custom and NON-OEM Recoveries are Recommended! More info...)
* With a SD Card at least 20MB remaining space, a system partition at least
12MB and a "/data" or internal memory with at least 10MB space remaining.
* Unlocked Bootloader (Bootloaders issued mostly in HTC, Motorola, etc. if Available)
NOTE : For users who are using DROID_U-ROOT_******--SIGNED.zip,
If installation fails, try these two packages.
DROID_U-ROOT_******_GB--SIGNED.zip contains Superuser files by @ChainsDD
while, DROID_U-ROOT_******_ICS+--SIGNED.zip contains SuperSU files by @Chainfire
(ICS+ Means its for Android 4.0 to 4.2)
COMING SOON:
* v 1.0.21 *
BIGGEST UPDATE EVER!
-- Fixed TYPO code in updater-script for GB Edition.
-- updater-script would be obsolete, we will now using the
binary source from @ClockWorkMod (coding)
to ensure rooting process!
-- More permissions fixes using scripts to ensure it's integrity!
-- Other architectures (x86, MIPS, etc.) would be available!
Version Changelog:
* v 1.0.1 *
-- Properly Signed all packages using APK-Multi-Tool (Hope it's more compatible!)
-- Dummy file contained in init.d directory in order to sign the whole package! (It will call "su" binary at boot)
* v 1.0.0 *
-- Initial Release

1. Information about ROOT
-------------------------------------------------------------------------------------
More info at: http://en.wikipedia.org/wiki/Android_Rooting
Android rooting is the process of allowing users of smartphones, tablets, and other
devices running the Android mobile operating system to attain privileged control
(known as "root access") within Android's sub-system.
Rooting is often performed with the goal of overcoming limitations that carriers and
hardware manufacturers put on some devices, resulting in the ability to alter or
replace system applications and settings, run specialized apps that require
administrator-level permissions, or perform other operations that are otherwise
inaccessible to a normal Android user. On Android, rooting can also facilitate the
complete removal and replacement of the device's operating system, usually with a
more recent release of its current operating system.
As Android derives from the Linux kernel, rooting an Android device gives similar
access administrative permissions as on Linux or any other Unix-like operating
system such as FreeBSD or OS X.
Root access is sometimes compared to jailbreaking devices running the
Apple iOS operating system. However, these are different concepts.
Jailbreaking describes the bypass of several types of Apple prohibitions
for the end user: modifying the operating system (enforced by a "locked bootloader"),
installing non-officially approved apps via sideloading,
and granting the user elevated administration-level privileges.
Only a minority of Android devices lock their bootloaders?nd many vendors such
as HTC, Sony, Asus and Google explicitly provide the ability to unlock devices,
and even replace the operating system entirely.
Similarly, the ability to sideload apps is typically permissible on Android devices
without root permissions. Thus, it is primarily the third aspect of iOS jailbreaking
relating to giving users superuser administrative privileges that most directly
correlates to Android rooting.
2. Advantages and Disadvantages of ROOT
-------------------------------------------------------------------------------------
An Android Device with a ROOT Access can give more functionality, such as by
Optimizing Performance both Software (Kernel, ROM) and Hardware (CPU, RAM, SoC)
Longing Battery Life, Uninstalling unwanted system apps, Forcibly transfer the app
to the SD Card (Even it's not supported) etc. All of these functions can separately
install using apps with a special SU (Root binary) system call.
Many users says that ROOT Access was a great function for a Android device.
But ROOT can cause vulnerabilities on your device and it's potentially dangerous
just because it can access deep down into a Android Sub-System such as modifying
system files, depending of which particular files or binaries would modify it by
users.
3. What are the requirements to make it work?
-------------------------------------------------------------------------------------
In order to make it workable smoothly, you/users must comply these requirements;
* Android 2.3 Gingerbread to 4.2 Jelly Bean (Not yet sure for KitKat)
* An Android Device with a workable Recovery Mode Console.
Custom and NON-OEM Recoveries are Recommended!
(More info: http://www.androidcentral.com/what-recovery-android-z)
* With a SD Card at least 20MB remaining space, a system partition at least
12MB and a "/data" or internal memory with at least 10MB space remaining.
This package will install a Superuser/SuperSU app in system/app/ directory, then
the su binary will install in a system/xbin/ directory. While the other functions
will be informed how at XDA forum.
4. How to install DROID UNIVERSAL ROOT?
-------------------------------------------------------------------------------------
BEFORE INSTALLATION...
Reboot your device to recovery mode, booting IT can be in different ways.
Case #1: Turning off the device and wait in a seconds to shut, and pressing
BOTH Power, Volume Up and Home Hard Buttons. This case are applicable
in many Samsung or other devices which it has a center button (HOME).
Case #2: Turning off the device and wait in a seconds to shut, and pressing
BOTH Power, and Volume Up Buttons. This case are mostly applicable
to the devices without a center button. (Soft Touch)
In some recoveries, some of them doesn't have a "select zip from sdcard" option.
So make sure you must rename the package to update.zip
INSTALLATION...
After that, Use the volume button to move, and home/menu/power button to select.
Some devices can select by tapping. Choose "select zip from sdcard" or
"select update.zip from sdcard". It will run if you rename this package
to update.zip!
AFTER INSTALLATION...
Reboot your device, wait for a moment to boot, and open your launcher menu.
When the Superuser/SuperSU app appeared, it means that you are ROOTED.
5. Compatibility Notice
-------------------------------------------------------------------------------------
NOT ALL ANDROID DEVICES are 100% workable in this package.
Many devices may not be easy to install cause of security features
such as OEM Recoveries build and provided by own manufacturers,
and locked bootloaders which it has a ability to restrict sideloading files
except their Official OTA Updates. It should be unlocked right away before
this procedure.
For users experienced Error 0 by installing this package, simply replace the
update-binary file from any of your stable update-binary.
Open the package using WinRAR then...
* META-INF/
* com/
* google/
* android/
! update-binary <<< Should be like this
* updater-script
* CERT.RSA
* CERT.SF
* MANIFEST.MF
To avoid device crashes, please make a backup through ADB (Android 4.0+ only) or
Custom Recovery (e.g. CWM). The developer is not responsible for Device Crashes,
Bootloops and other relative damages on your device.

Idk what this is. OP says Stable and beta. I downloaded your signed beta rc 1.0 and it is nothing but supersu apk, su binaries, and busy box. The updater script seemed weird as supersu does all of the work in the updater-binary. Anyway, I have no idea what this is supposed to be. You might want to ask @Chainfire before repackaging his stuff though. It doesn't appear in your OP that you give him credit.

LazyFlasher & no-verity-opt-encrypt
INTRODUCTION
Hello Users and Developers of XDA!
LazyFlasher is a custom kernel flashing tool designed to make it easy to dynamically modify ramdisks and inject kernel binaries into the current boot image.
It's the swiss army knife of kernel flashing for use in Team Win Recovery Project.
The intent behind it was to allow a 1 custom kernel fits all approach, where your users can flash single zip on any ROM for a particular device,
allowing your kernel to be compatible with the vast majority of custom ROMs already out there. It takes away the pain of building custom boot.img
for each and every variant a user requests and puts it into 1 low maintenance intelligent universal flashable zip.
You might already know of @osm0sis's AnyKernel2 project. This approach is similar to that. Back in late 2015 I decided to design a more compatible, more friendly, and more feature filled version. Since then, AnyKernel2 has apparently improved a lot so if LazyFlasher doesn't accomplish what you need, AnyKernel2 probably will.
LazyFlasher does not currently support ELF boot images.
For users of no-verity-opt-encrypt: This thread can also be used to discuss the no-verity-opt-encrypt project which is just a minimal version of the LazyFlasher framework.
Disqus thread: https://www.xda-developers.com/xda-...-is-an-alternative-to-the-anykernel2-project/
THE GITHUB REPOSITORY
You can find LazyFlasher's development and download it here: https://github.com/jcadduono/lazyflasher
LazyFlasher source code is distributed under the BSD 2-clause license. You can do anything you want with it, however, some of the binaries used by it are under GPLv2 or GPLv3 licenses.
FEATURES
ChromeOS support (ChromeOS test-key signing and recognition)
MediaTek device support (MTK headers)
SELinux policy injection support via sepolicy-inject
Example scripts to disable dm-verity or forced encryption during the install process (010-no-force-encrypt, 015-no-dm-verity)
A process that executes a sorted list of scripts for making the desired modifications (separate from the framework)
Handily unpacks, decompresses, applies changes, compresses, and repacks boot images quickly and safely
Supports Gzip, LZ4, Bzip2, and LZO ramdisks. Support for LZMA and XZ is a work in progress
Supports arm (armv7), arm64 (aarch64), x86 (i386), x86_64 (amd64), mips, and mips64 architectures
Supports dtb.img replacement (place it in the root folder named "dtb.img")
Scans fstab and partition locations for the boot partition, optionally allows a preset location
Intelligently installs kernel modules by copying the previous layout of /system/lib/modules and creating symlinks
Creates modprobe supported /lib/modules aliases if kernel modules are included in the installer (030-kernel-modules)
Installs new files to the ramdisk and sets their permissions automatically based on file type from ramdisk-patch (020-patch-ramdisk)
Includes an optional bbe tool for applying binary patches
Unnecessary architectures and tools can be removed to save space
Many useful functions and variables included in the patch.d environment to simplify modification/patching scripts (patch.d-env)
Simple "make" build system
SETTING UP LAZYFLASHER
LazyFlasher is only designed for building on Unix based systems such as Linux, Mac OS X, and FreeBSD.
To download it (feel free to fork it so you can have a copy on your GitHub to modify instead!):
Code:
cd ~/build
git clone -b kernel-flasher https://github.com/jcadduono/lazyflasher.git
cd lazyflasher
To use LazyFlasher, you'll probably want to take a look at the Makefile, config.sh, and META-INF/com/google/android/update-binary (a shell script).
There's a few things you can change there to personalize it to your needs.
(make another git commit to save your setup!)
You should also check out the README! There is a lot of useful information there.
Once the installer is set up to your liking, all you have to do to build it is copy the resulting kernel binary from your kernel build output into the lazyflasher folder.
If you have built with kernel modules (make modules_install), copy build/lib/modules -> lazyflasher/modules.
Now simply run:
Code:
make
A TWRP flashable zip and sha1sum is created!
You should consider signing the zip with AOSP test-keys so that users can verify its integrity before flashing it.
LOOKING TO TRIM DOWN THE INSTALLER?
I have forked the kernel-flasher branch to a branch called kernel-flasher-arm64-minimal. This provides all the features of kernel-flasher except sepolicy injection and bbe, and only supports arm64 devices. It reduces the minimum zip size from 1860 KB to 200 KB.
You can use this branch instead if you like. If you're using another architecture, just look at the trimming commit as an example and apply it for your arch.
BUT I AM ON LE WINDOWS!
How did you build your kernel binary?!
Anyways, there is an alternative for building it on Windows.
You can download the LazyFlasher kernel-flasher branch as a zip file from GitHub and extract it somewhere on your PC.
Make your modifications using Notepad++.
You can then use a tool such as 7-zip to create a zip file by selecting everything in the folder, right clicking, and going to 7-Zip -> Add to "lazyflasher.zip".
LIMITATIONS AND KNOWN ISSUES
It will not run on TWRP built in Android 4.3 or earlier (usually builds older than 2.8.0.0)
Requires Busybox to exist in the TWRP build. All official builds should have this.
There may occasionally be some devices that are unsupported due to extreme modifications made to the boot image format by the manufacturer. If you have one of these devices, feel free to contact me and I will try to add support for it if it is worth the effort.
If you have an issue, please gather a recovery.log from TWRP after flashing and I will try to look into it. I can't do anything to diagnose your problem without a recovery log.
Code:
adb pull /tmp/recovery.log
JUST WANT TO DISABLE VERITY/ENCRYPTION?
You can build lazyflasher by itself, empty, without a kernel image or modules and flash it!
It's already set up to automatically disable verity and make encryption optional.
Alternatively, there's a branch already set up called no-verity-opt-encrypt. You can find prebuilt official zips at: https://build.nethunter.com/android-tools/no-verity-opt-encrypt/
WHO ELSE IS USING LAZYFLASHER?
I'll keep a list here of cool projects that are using it. Feel free to ask for yours to be added.
The Kali Linux NetHunter project (GitHub, Website)
no-verity-opt-encrypt, no-verity-force-encrypt, twrp-data-fstype-swap (Website/Download)

nope, no plans to support that device, surprised they are still out there, i would expect most to be dead emmc by now. :|
you can probably modify boot-patcher.sh to copy partitions to split-img folder then flash them back instead of using bootimg
i don't even know if lazyflasher's binaries will run on any of the i9100 twrp builds. might be too old.
if i can get an example layout of i9100's partitions i can fork it to a new branch, called kernel-flasher-sgs2 and make it compatible for you guys.

They are too old but still supported by lineage 14.1 and official twrp 3.0.2-1 without any problems
osmOsis dev of anykernel2 said that i9100 and older devices are having different boot img header format when i tried to run anykernel2 script it says Android magic is not found something like that
interesting tnx
Wow...
I'm just recognizing now, how powerful lazyflasher is ...
Setting default.prop values and settings. Disable Encryptions and so on. Wish I could contribute something but I'm still learning how it works. For now I've just included lazyflasher into my PATCH to disable DM Verity and forced Encryption and to make some edits on the default.prop. That's really useful since the build.prop doesn't allows such deep changes.
@jcadduono what would be in the Theory possible with the Lazyflasher? Could we add things like Gouverneurs or default Kernel Clockings? Init.d Support? Sorry if I sound noobish :angel:
So, uh, is there a TL;DR for lazy people? :silly: :laugh:
@jcadduono this is absolutely awesome. thank you for your hard work.
Hope that someone can dev nethunter to Asus zenfone 5 t00f :fingers-crossed:
can you please make a tutorial vedio of it because i don't get it and i'm sorry for my stupidity
Will it work for Android Oreo / LOS 15?
Did anyone succeeded in removing dm-verity? I got this error
good
