DiSCLAiMER: USE AT YOUR OWN RiSK

Prerequisite:

1. After grabbing the latest Firmware, before Flashing using Odin, you must prepared the boot image file first.
   [Note] i'd use Child files instead Download one file of the latest Firmware (A035FXXS8CYA3 - Release Date : 2025-02-13).
   
   • AP_A035FXXS8CYA3_A035FXXS8CYA3_MQB91821401_REV00_user_low_ship_MULTI_CERT_meta_OS13.tar.md5 (4.05 GB)
   • BL_A035FXXS8CYA3_A035FXXS8CYA3_MQB91821401_REV00_user_low_ship_MULTI_CERT.tar.md5 (4.18 MB)
   • CP_A035FXXS8CYA3_CP28973379_MQB91821401_REV00_user_low_ship_MULTI_CERT.tar.md5 (12.56 MB)
   • HOME_CSC_OLE_A035FOLE8CYA3_QB92096408_REV00_user_low_ship_MULTI_CERT.tar.md5 (116.33 MB)
   Select the "AP" file and extract "boot.img" file using 7zip or Peazip then copy into your smartphone internal or external storage.
   
   
   


2. Install and open "Magisk App" to patching the boot image file, tap on the install section and navigate "boot.img" file. Reach out to the location and press the boot file to start the patching process. From this method, the "magisk_patched.img" file will appear in the folder "Download" on internal storage. Recopying the "magisk_patched.img" to your local hdd PC/Laptop, then compress to ".tar" format using 7zip or Peazip.
   
   
   


3. Now, install and open Odin Tool (version 3.14.4) to starting flashing your phone. Select and navigate as below:
   • [BL] : BL_A035FXXS8CYA3_A035FXXS8CYA3_MQB91821401_REV00_user_low_ship_MULTI_CERT.tar.md5
   • [AP] : AP_A035FXXS8CYA3_A035FXXS8CYA3_MQB91821401_REV00_user_low_ship_MULTI_CERT_meta_OS13.tar.md5
   • [CP] : CP_A035FXXS8CYA3_CP28973379_MQB91821401_REV00_user_low_ship_MULTI_CERT.tar.md5
   • [CSC] : HOME_CSC_OLE_A035FOLE8CYA3_QB92096408_REV00_user_low_ship_MULTI_CERT.tar.md5
     The Difference – CSC and HOME CSC
     --- [CSC] ---
     If you want Odin to wipe all third-party apps, data, and settings and perform a factory reset while installing the firmware, you should add the CSC binary to Odin. The image, video, audio, and all other files present on the internal storage will be deleted. Flashing the CSC binary will result in a clean installation. If you feel that your phone is slow and experience any lag or misbehavior, wiping the phone might help fix those issues.
     --- [HOME CSC] ---
     If your purpose is to just re-install the firmware or update your Samsung device’s software without wiping your apps, all user data, and settings, you should go with the HOME CSC binary. Choosing this file will only affect the software version of your phone while keeping everything intact.
     
   Then click on "Start" button and wait until flashing completed.
   
   
   


4. iMPORTANT After flashing completed and while your phone restarting, it will stuck on "boot logo (bootloop)" but DON'T PANiC it happen because the "bootloader unloked", just press and hold [Power], [Vol+] and [Vol-] until entering to "Download Mode".
   Open Odin Tool again then Flash the patched boot image file that already prepared on step.2.
   Select and navigate as below:
   • [AP] : "magisk_patched.img.tar" then click on "Start" button and wait until flashing completed.
   
   
   


5. Now your phone won't stuck on "boot logo (bootloop)" after restarting (problem solved).
   All Done and enjoy!
