SYSTEMLESS DevBase has been developed and physically tested on S7 Edge (G935F), so main thread containing the most detailed description you can find here:
>> [SAMSUNG][6.0+] SYSTEMLESS DevBase | Encryption support | Stock OTA updates <<
However, it should work on ALL SAMSUNG DEVICES running Android 6.0+, so if you are Galaxy S6 Edge (G925xx) owner - please place your feedback & discussion here to let me know about device-specific issues or to let me know that everything works perfect
---------------------------------------------------------------------------
Are you tired with traditional custom ROMs?
Do you miss custom ROMs but you would like to have encrypted /data (for privacy/security reasons)?
You are in the right place! I present you SYSTEMLESS DevBase - an SYSTEMLESS equivalent of my previous work (for older devices)
Prerequisites:
- Samsung device running stock or stock-based Android 6.0+ (mandatory!)
- Rooted device - SuperSU v2.76+ installed in SYSTEMLESS mode (mandatory!) (*)
- Stock, untouched /system partition (not mandatory, but recommended for working OTA)
- Stock recovery (not mandatory, but recommended for working OTA)
(*) NOTE: The latest CF-Auto-Root image for G925F contains SuperSU v2.74 which does not support SYSTEMLESS solutions (su.d is not triggered early enough). It is NOT enough to update it via PlayStore to the newest version and update su binaries! You need to update it using TWRP / FlashFire installable ZIP from THIS STABLE or THIS BETA thread. Alternatively you can use "EverRoot" -> "Inject SuperSU" option in FlashFire even if you are rooted already by CF-Auto-Root (it will update SuperSU in the same way as flashing ZIP).
SYSTEMLESS DevBase:
1. Benefits / main features:
- Works with encypted /data partition
- Working official OTA updates! (see Tips & Tricks)
- Does NOT perform any phisical modifications in /system
- Does NOT perform any additional changes/patches to the kernel
- Removed KNOX warnings (systemlessly removed SecurityLogAgent)
- It contains SYSTEMLESS BusyBox (bionic, the most stable and respected release)
- It allows you to easily modify most of files & apps in your /system - SYSTEMLESSLY (see Tips & Tricks)
- It does not interfere with Magisk! You can use Magisk in paralell with SYSTEMLESS DevBase if you need it for your favorite module.
2. Systemless Safe De-Bloat (more info below):
What does it mean and why is it called "safe"?
- ONLY apps available in stores will be systemlessly removed from the ROM, so you can easily (re)install any of these app if you like
- ONLY pre-installed system apps are will be systemlessly removed, DevBase installer never touch any updated app nor app installed manually from store
Thus, the following conclusions can be drawn:
1. If you install my SYSTEMLESS DevBase directly over working stock ROM - in most cases almost all these apps will remain untouched, because almost all apps have been updated already (stored on /data). But then you will be able to remove any useless app using the "Application manager" -> [Name_Of_App_To_Remove] -> MORE -> Uninstall updates. NOTE: App will disappear arter reboot and will be visible even in Titanium Backup!
2. If you perform "Wipe data" directly before installing SuperSU and my SYSTEMLESS DevBase (before you let to install app's updates) - then all apps listed below will be removed. If you would like to use any of these apps - just install it manually from appropriate store. Installed manually app will not be removed during the next DevBase update or re-install.
Removed apps list (depends on the device, should cover all devices starting from Galaxy S5):
ChatON
Chrome
Drive
Dropbox
EditorsDocs
Evernote
Excel
Facebook
FB Messenger
FB Pages Manager
Flipboard
Google+ / Photos
Group Play
Hangouts
Instagram
OneDrive
OneNote
PEN.UP
Play Books
Play Games
Play Movies
Play Music
Play Newsstand
PowerPoint
Skype
Smart Remote
WhatsApp
Word
NEW! Safe De-Bloat feature automatically detects and systemlessly removes apps not listed above, but present in your CSC package
3. Systemless CscFeature MOD (enabled some built-in, hidden features):
- Added shutter sound menu in Camera app
- Sending/receiving MMS without data on
- Show SMS/MMS sending time instead of receiving
- Added "Exit Internet" option to stock browser
- Added call button in Phone Logs (**)
- Added "Call/Message block" option in Settings
- Added symbols as secondary keys in Samsung keyboard (**)
- Call Recording (manual control, added "Record" button)
(**) may not work starting from Android 7.0 Nougat
Installation:
1. FlashFire app (recommended ***):
- Open file using "Flash ZIP or OTA" option
- UNTICK "Mount /system read/write" [extremely important for working OTA!]
- Enable "EverRoot" -> "Inject SuperSU" option if necessary (see NOTE above (*))
- Tap "FLASH"
2. TWRP recovery:
- Tap "Keep Read Only" on the Welcome screen [extremely important for working OTA!]
- Open file using "Install" option (use extSdCard or OTG storage in case of encrypted /data)
- Confirm flash by swiping right
- Tap "Reboot System"
NOTE1: One additional auto-reboot may be performed at first boot. It is not a bug (may be required for systemless build.prop support - see Tips & Tricks for more explanations)
NOTE2: Do not worry about red "mount /data failed..." messages displayed in TWRP in case of encrypted /data (installer will do the work anyway!)
(***) As far as I know - FlashFire is the only flashing tool with full access to /data during flash in case of encrypted devices. It is also the only tool which allows you to perform full backup/restore of partitions, including encrypted /data. It does NOT require custom recovery to work!

Tips & Tricks
1. OTA updates:
- Basically, the only thing you need to take OTA update is to perform "Full unroot" in the SuperSU app. However, a better way is to use "unroot2ota" terminal command, because this will not remove DevBase boot script from /su/su.d and the only thing you will need to re-activate SYSTEMLESS DevBase (and all your systemless MODs) after performing OTA update is just re-root your device with CF-Auto-Root.
- If you flashed custom recovery like TWRP - it is mandatory to restore your stock recovery (otherwise OTA will not work). You can do it using FlashFire app (the easiest way) - just open recovery.img file (extracted from your original FW) using "Flash firmware package" option, disable "Preserve recovery" option and then tap "FLASH". EDIT: Starting from version v1.2 there is a new "unroot2ota" feature which allow you to restore stock recovery using /system/recovery-fromm-boot.p file. There is no guarantee to perform it successfully (even if there is no error message) but in most cases it works well (tested on Nougat beta). Please go to recovery before you try to get OTA to check if you have stock recovery already after performing "unroot2ota" (if not - you need to use PC Odin to flash recovery.img packed in tar file).
- It is recommended to temporarily disable "Auto-update apps" in Play Store settings before you unroot your device. It will prevent updating applications covered by Safe De-Bloat list, as there apps will temporarily appear until you re-root the phone after performing OTA update.
Note (devices which use dm-verity): You should never allow /system modifications in TWRP, never allow to remount /system r/w in any app (e.g. Root Explorer, FlashFire, etc.) and never flash a ZIP file which could modify your /system or remount it r/w. Failure to follow these recommendations will break dm-verity verification and will cause, that your device may not be able to boot with the stock kernel (you will need to re-flash your original FW using PC Odin to make your device bootable).
2. Making your own modifications:
- You can systemlessly replace any existing system app by modded one. Just put modified app to /data/devbase/system/app or /data/devbase/system/priv-app and then reboot your device
- You can systemlessly replace jar or apk in /system/framework. Just put modified one to /data/devbase/system/framework and then reboot your device (NOTE: framework support has been added for advanced users -> there is high risk of bootloop if you do something wrong!)
- You can systemlessly add or override any line in /system/build.prop. Just put (only new or changed) line to /data/devbase/system/build.prop and then reboot your device (NOTE: one additional auto-reboot will be performed if /data/devbase/system/build.prop file has been added, modified or removed. It is not a bug - it is required for the changes in /data/devbase/system/build.prop to take effect!)
- You can systemlessly replace any existing file in /system/csc and /system/etc (but NOT in subdirectories). Just put modified copy of a file to /data/devbase/system/csc or /data/devbase/system/etc and then reboot device
Limitations: original app or file MUST physically exist with the same name in /system, you can NOT add a new app or file this way!
Example 1 (Ad-Blocking): Download the latest Ad-Blocking ZIP installer from THIS thread. Extract "hosts" file (placed in /system/etc inside ZIP file), then copy it to /data/devbase/system/etc, set rw-r--r-- (644) permissions and then reboot device
Example 2 (modded SystemUI): Create "SystemUI" directory in /data/devbase/system/priv-app and then put modified "SystemUI.apk" file into it. Set rwxr-xr-x (755) permissions to "SystemUI" directory, rw-r--r-- (644) permissions to "SystemUI.apk" and then reboot device
Example 3 (De-Bloating a bit more): You can just create empty directories in /data/devbase/system/app (or priv-app) corresponding to applications in /system/app (or priv-app). Alternatively (more advanced method), you can add an app to modded enforceskippingpackages.txt file (you can find it in /data/devbase/system/etc or /data/devbase/system/csc_contents, depending on the original location in /system) and increase number in the 1st line. Second method should not be used by beginners (without a basic knowledge related to UNIX text format)
3. How to manually maintain the newest ROM version:
If you do not care about OTA - you can manually update your device to the newest ROM available @ Sammobile, keeping your original CSC (you need multi-file original FW, I mean separate files for BL/AP/CP/CSC). You need to download 2 ROMs: ROM with the newest changelist and the latest ROM containing your original CSC. Extract both and open in PC Odin BL/AP/CP files from the ROM with highest changelist but open CSC file from the ROM containing your CSC (I recommend to use HOME_CSC_* file to avoid auto-wipe-data). Flash such "mix", re-root and enjoy

There is new version available
Changelog
v1.1:
- Added SYSTEMLESS support for /system/framework
- Added SYSTEMLESS support for /system/build.prop (overrides & additions)
- Added major Android update detection (auto-remove mods for older API to prevent bootloops & FCs)
- Added BusyBox bionic (the most stable and respected release)
- Added logging to /data/devbase/last_boot.log (API & errors)
- Added SuperSU boot patcher version checker (exits su.d boot script if < 2.76)
- Added "Please DO NOT wipe /cache" warning in case of encrypted devices and TWRP recovery
- Minor changes & optimizations in the shell code
- Added SYSTEMLESS DevBase uninstaller
Download link:
>> SYSTEMLESS_DevBase_v1.1.zip <<
Since new version has many more features -> there are more possibilities of bootloop (especially if you are playing with framework mods). I have created DevBase remover to let you get out from bootloop. Of course uninstaller does NOT "know" which mod caused the problem, so it will not remove any file from /data/devbase directory, it will remove only /su/su.d/0000000devbase boot script to make your device bootable (again) so you can manually delete problematic mod:
>> SYSTEMLESS_DevBase_remover.zip <<
Another update:
v1.3:
- Fixed CscFeature MOD (e.g. G920I case, now should work with all Samsung devices/variants)
v1.2:
- Added info in Settings/About device/Software info/Build number (can be overrided by editing /data/devbase/system/build.prop)
- unroot2ota: added ability to restore stock recovery using /system/recovery-from-boot.p file (no guarantee)
- unroot2ota: check /system partition for common modifications before unroot
- Minor changes & improvements in the shell code

The link for "Debloat & Tweak" is down, could someone please provide me with a working link ?
Some Custom OS Like Lineage OS, Evolution X, etc. have a common problem - Error in Single Reception.
To fix Follow the following Steps -
DISCLAIMER - I am not responsible if any damage occurs.
1) Flash Magisk Root Manager.
2)Open Magisk Manager and Download and Install given Modules
- Riru (Riru - Core)
- Riru - EdXposed
**REBOOT**
3)Open EdXposed Manager (You will be redirected to Github to download the latest apk), Go to Modules and Enable EdXposed Manager.
**REBOOT**
4)Open EdXposed Manager, Go to Downloads, and Search LTE Mobile Signal Fix.

Video to install EdXposed - https://youtu.be/MezpjCoDRVQ
I have successfully degoogled and debloated the latest OOS (atm 10.3.8) and have a working microg setup using nanodroid package. Battery life is nice. 45hrs with 10,5hrs SOT on the first go! Not any unwanted background data moving, success I'd say! So for anyone interested, here are roughly the steps I took.
I couldn't deodex the services.jar with VdexExtractor so I used FakeGapps from Edxposed. Works!
In following guide we will first get a factory state OOS with twrp and root WITHOUT internet. Then we uninstall system app 'android setup', allow internet, get Edxposed working and FakeGapps installed. Then we install Nanodroid package from twrp to get a working microg and setup it and debloat. + Disable trackers using App Manager from F-droid repositories or github. Get it ready for sideloading or use adb. Support the developer!
General guide (everything gets erased):
1. Pure factory installment using MSM tool for 10.3.8 from Oneplus 6 unbrick tools. (XDA forum)
2. The phone starts, go through the initial setup bypassing everything you can. DON'T SETUP ANY WIFI!
3. Immediately switch off mobile data from quick settings, just in case. We dont want android setup to update any apps.
4. Enable unlocking the phone, reboot to bootloader
5. Unlock the bootloader (fastboot oem unlock)
6. Do parts 2 and 3 again (choose Oneplus slate font at this time if you ever want it to work)
7. Enable USB debugging, connect to computer, check 'adb devices' to get the window to allow the computer to appear. (The daemon needs to be running)
This all was to get the phone into pure factory state without automated changes, bootloader unlocked and adb working.
8. Install twrp and magisk. Boot up the phone.
9. Remember! No internet connections yet! Uninstall the system app 'Android Setup'. I used sideloaded AppManager for that. You'll know when you have uninstalled the correct app when the notification of android setup disappears.
10. Reboot
11. Now you can connect to internet.
12. In magisk, install Riru core, (mandatory reboot here!) and Riru Edxposed (2nd reboot)
13. In Edxposed, install FakeGapps and activate it. Reboot.
13. Now you can connect to internet.
This was all done to setup the phone for Nanodroid package and get safely to internet without unwanted updates.
14. Download a nanodroid package from github. I used just the microg version. Flash it from twrp. It should debloat some necessary google stuff, install aurorastore and aurora services and straight up working microg.
15. Check if microg is working and do registrations and enable cloud and location stuff. Reboot.
16. Install any app that uses google cloud service for push notifications and check from microg settings that it shows in the list. Don't continue installing any such apps until it does. Reboot or troubleshoot if necessary with microg related info.
17. Back up current setup from twrp for fallback.
18. Debloat to your heart content, except only disable and force stop the play store. In my case the app is still the official one. Don't use.
19. From AppManager, run disable all trackers, including system apps from 1-click ops.
There! Use some time, and if everything is to your liking, make a backup. Remember to disable trackers from every app you install after you have configured it.
Sidenote: Aurora store did not work when installed systemlessly, but worked fine as a user app
Reserved, just in case
How do you make a split apk into a system app?
I am currently using Redmi Note 8 Pro (begoniain)
Rooted using Magisk. (v24.3)
TWRP Recovery installed.
Zygisk enabled.
LSPosed Framework v1.8.2 (6519) installed
MIUI version:
MIUI Global 12.5.3
Stable
12.5.3.0(RGGINXM)
Android version:
11 RP1A.200720.011
I have tried the following methods (unsuccessfully):
Convert to System app using Lucky Patcher (with and without Magisk module)
Manually copy the folder from /data/app/~~..../package.name-..... to /system/priv-app/
Convert to System app using Magisk module - App Systemizer
Manually copy the folder from /data/app/~~..../package.name-..... to /system_root/system/priv-app/ from Recovery mode
Which app? What errors are you getting? Maybe you have already found a solution?
