My Device is A300F (United Arab Emirates, XSG Product Code). From Ashyx's v3.0.2-1 I've been updating pvineeth's A300H Recovery upto v3.2.1, didn't update to 3.2.3-0 yet, and I used image files from the Official TWRP site (No Issues at All flashed charmly). Till v3.2.1 MTP & O-T-G didn't work at all. Does it work in the latest 3.2.3 ?
The one You linked to Ashyx's (post 80) works, but it's outdated !

i tried every twrp version here, but none works on my a300f rooted kitkat 4.4.4
the only one that boots is the 3.0.0.0 version, but the screen is ghosted, one cannot push anything.
the others dont boot (always "downloading..." screen after trying to get to recovery)
is there an older twrp maybe that boots with kitkat?

I've rooted my phone, but what superuser app can I use? They seem to all be gone from the play store. A recommendation would be appreciated.

Hello all,
The link for the GoogleApps (opengapps.org) in the "how to" is out to date.
Do you think that we can replace it by this one ?

    Bevor you do something with your Device do a Backup of all your Data (Contacts, Pic´s ect.) outside of your Device (in a Cloud or on your PC)​
    I'm not responsible for bricked devices, dead SD Cards, broken phone chargers etc.​
    You do all at your own Risk!​

    If you are new, just work the first 3 steps from top to bottom.​

    Flash Root & Odin3:
    At the https://autoroot.chainfire.eu/ site you can Download the the Root File for your Device (Link to A300FU). When you Downloaded the "CF-Auto-Root-xxx.zip" File unzip it. In this zip you will find the Odin3xxx.exe and the Root .tar.md5 File
    You need this Odin3 tool also for TWRP and going Back to Stock Rom
    For Root: Make sure your device is in ODIN download mode (you can get there by holding VolDown+Home+Power when the device is turned off), then start the included Odin3xxx.exe file, press the PDA/AP button, select the Root .tar.md5 file, and click Start, never interrupt this action! You can find more detailed instructions and assistance at [CENTRAL] CF-Auto-Root Thread


    Flash TWRP:
    You can Download the TWRP File at the [RECOVERY][ROOT][TWRP 3.0.2-1]Samsung Galaxy A3(2015) SM-A300F/FU/G/H/M Thread. I recommend the Build from Post 80 it has working MTP & OTG for the FU Device!
    To Install Start download mode (you can get there by holding VolDown+Home+Power when the device is turned off), then start the Odin3xxx.exe file, press the PDA/AP button, select the TWRPxxx.tar file, and click Start, never interrupt this action! After Reboot you can get there by holding VolUp+Home+Power when the device is turned off.
    There are also a TWRP 2.8.7.0 and a TWRP 3.0.0-0 but both have small bugs so i recommend TWRP 3.0.2-1 only if you have Problems try to downgrade
    TWRP Bugs:
    TWRP 2.8.7.0 Can only Install CM12.1 ROMs, it has no MTP & no OTG
    TWRP 3.0.0-0 Can only Install CM13 ROM & it has no MTP but OTG is Working
    TWRP 3.0.2-1 Can not install @cbolumar ROMs and the Build from Opening Post has no OTG
    TWRP 3.1.0 Only tested with LineageOS, it still has no MTP!!!


    Flash a Custom ROM:
    You can Install a ROM now with TWRP you can enter TWRP by holding VolUp+Home+Power when the device is turned off.
    In TWRP IT IS HIGHLY RECOMMEND TO DO FIRST A BACKUP! (I Recommend to placed at the SD Card)
    Backup -> Storage : Micro SDcard -> Ok -> [x] Boot, [x] System, [x] Data, [x] Cache, [x] Recovery, [x] EFS, [x] MODEM, [x] APNHLOS -> Swipe to Backup
    If anything goes wrong you can easy Restore your Device in TWRP without losing anything, so it's also recommended to Backup your Custom ROM
    Now you need your Custom Rom, Google Apps like Opengapps for ARM and i recommend latest Magisk[/URL, OR (if you prefer) [URL="http://download.chainfire.eu/supersu"]SuperSU to Manage Root Access.
    Place this zip Files at your Device (I Recommend to placed at the SD Card)
    Now you enter TWRP and go to:
    Wipe -> Advanced Wipe -> [x] Dalvik / ART Cache, [x] System, [x] Data, [x] Cache -> Swipe to Wipe
    Now go back to main menu and select:
    Install -> Storage : Micro SDcard -> Ok -> now choose your ROM zip first, you can "Add More Zips" and choose Gapps zip and if you want you can Add direct Magsik OR SuperSU zip as well -> Swipe to Confirm Flash
    After placing files the Device need a Reboot, at the First Start it will Install your Rom, so be patiently at first start!



    Flash Xposed:
    Magisk user on Android M (6.x) or better follow this Thread [2018.5.6][Magisk] Systemless Xposed v89.3/v90.2-beta3 (SDK 21-27) by topjohnwu

    SuperSU user on Android M (6.x) or better follow this Thread [OFFICIAL] Xposed for Lollipop/Marshmallow/Nougat/Oreo [v90-beta3, 2018/01/29]

    info:
    SDK 21: Android 5.0 | SDK 22: Android 5.1 | SDK 23: Android 6.0 | SDK 24: Android 7.0 | SDK 25: Android 7.1 | SDK 26: Android 8.0 | SDK 27: Android 8.1

    at CM12.1 ROM's Offical Xposed works fine.
    Download the "sdk22-arm" zip, and Install it with TWRP first start need a long time! be patient!
    After the Framework is installed you install the "XposedInstaller" apk, done.
    For stock rom you should visit [UNOFFICIAL] Xposed for Samsung Lollipop by arter97 but it´s for deodex'ed ROMs for this you should visit [Deodex][SM-A300] Deodex Thread for Samsung Galaxy A3

    Working only on MM touchwiz (tested by me on A300FU with TWRP 3.0.2-1)
    How to install:
    - Install this Xposed Installer App version http://forum.xda-developers.com/attachment.php?attachmentid=3383776&d=1435601440
    - Make a nandroid backup
    - Copy the Xposed file and the uninstaller to your sdcard
    - Flash "xposed-vxx.x-sdkxx-tw-armxx-custom-build-by-wanam-xxxxxxxx.zip" through a custom recovery (TWRP/CWM...)
    - Reboot and Waiiiiiiiiit, it may take several minutes to boot up depending on your Rom size.

    Flash Stock ROM:
    Download your Firmware at Sammobile than i recommend you to Wipe all (Advanced Wipe) in TWRP except the SDcard!
    Boot your Device in ODIN download mode (you can get there by holding VolDown+Home+Power when the device is turned off), then start the Odin3xxx.exe file, press the PDA/AP button, select the .tar.md5 file, and click Start, never interrupt this action!
    After doing this you lose TWRP and Root so if you need it you have to install it new.
    You should not try to Flash 4.x ROMs it could Brick your Device!
    With a Stock Marshmallow ROM it is recommended to use a Custom Kernel

    Nice guide. Which one would you recommend between the CM12.1 and CM12.1 RR?
    Also, for downgrading TWRP, you just need to flash the older version, right?

    Click to collapse

    Definitely CM12.1 RR!
    Right just flash first TWRP 2.8.7.0 via Odin3 install the ROM and than Flash TWRP 3.0.2-1 via Odin3, btw. the Build from post 80 has a working MTP and OTG in TWRP (only in TWRP not at the ROM!)
    And you can anytime time flash TWRP 2.8.7.0 again if you have to Install new :D
