Samsung / Reset, Flash & Recovery

Galaxy S24+

Official reset & flash steps, plus guided recovery if something goes wrong — every download clearly marked official or third-party.

Select your exact model variant first

Flashing firmware meant for a different region/carrier variant can cause serious issues (IMEI/baseband loss). Confirm your model code in Settings > About phone.

Device-Specific Warnings

Button combo
Force Restart: Hold Volume Down + Side (Power) button for 7 to 10 seconds. Stock Recovery Mode: Connect phone to PC via USB-C cable, power off completely, then hold Volume Up + Side button until Samsung logo appears. Download Mode: Power off phone, unplug cable, press and hold Volume Up + Volume Down simultaneously, and plug in USB-C cable connected to PC; press Volume Up at the teal screen.

CRITICAL SOC / REGIONAL SPLIT: Global/European/International/Korean models (SM-S926B, SM-S926N) are powered by the Samsung Exynos 2400 chipset, whereas US/Canada/China variants (SM-S926U, SM-S926U1, SM-S926W, SM-S9260) utilize the Qualcomm Snapdragon 8 Gen 3 for Galaxy. NEVER cross-flash Exynos firmware onto Snapdragon hardware or vice-versa. Additionally, US carrier models (U) and unlocked models (U1) enforce strict bootloader rollback prevention (SW REV check); Odin will reject any firmware package with a lower bootloader bit than what is currently flashed on the device.

  • Rollback Prevention (SW REV Check Fail): Samsung bootloaders permanently increment a hardware security fuse index when updated. Attempting to downgrade to a firmware with a lower binary bit (e.g. flashing Bit 1 firmware onto a device updated to Bit 2) results in an immediate Odin flash abort ('FAIL! (Auth)').
  • Cross-flashing Incompatible PIT files: Flashing a partition table (PIT) from an incompatible carrier or storage size (256GB vs 512GB) can destroy the UFS 4.0 partition layout and permanently corrupt EFS/NVRAM modem data, resulting in loss of IMEI and cellular connectivity.
  • Flashing without PC Handshake: On One UI 6.1, recovery mode cannot be entered via button combination unless a valid USB data connection (e.g. to a PC or active USB accessory) is detected during boot.
  • Cable disconnection during AP (system.img.lz4 / super.img) flashing: Disconnecting the USB cable mid-flash will leave the primary operating system slot corrupted, placing the phone in emergency recovery.
