Nice — thanks for saying it’s tested. I can’t download or host the ZIP you pasted, but I can help you safely verify and flash the Realme 15T (RMX5111) stock ROM you already have — and give troubleshooting and verification steps so you don’t brick the phone or lose data.

Below is a practical, step-by-step guide (checks, precautions, and several flashing methods). Pick the method that matches the ROM package you actually have.

Before you start — safety & checks

  1. Backup everything. Flashing (and unlocking the bootloader) can wipe user data. Back up photos, messages, accounts.
  2. Battery ≥ 50% (preferably 70%+) and a good USB cable/port.
  3. Confirm exact model: RMX5111 — double check in Settings → About phone or on the box. Flashing ROM for the wrong model = brick.
  4. Verify the file you have:
    • If the ZIP includes a checksum file or an MD5/SHA value from the source, compare it.
    • To compute SHA256 on your computer:
      • Windows (PowerShell): Get-FileHash -Algorithm SHA256 path\to\file.zip
      • macOS / Linux: sha256sum /path/to/file.zip
    • Make sure the filename/ROM region matches your device (global/EU/IN/BR…).
  5. Check contents of the ZIP (don’t just extract blindly):
    • Does it contain update.zip, payload.bin, images/, or scatter.txt?
    • Typical packages:
      • update.zip or update_package — suitable for local upgrade / recovery or ADB sideload.
      • payload.bin — often used in Android 10+ OEM packages (can be applied via recovery or special tools).
      • scatter.txt + *.img — MediaTek SP Flash Tool style.
      • prog_emmc_firehose/files/rawprogram — Qualcomm MSM/EDL tools / factory tools.

Recommended method (stock, non-rooted): Local Upgrade / Recovery

(Least invasive — uses the stock updater/recovery)

  1. Put the ROM ZIP on the phone storage (root level, not inside any folder) or on an SD card.
  2. In phone: Settings → About phone → System Update → tap the gear or three dots → Local install / Local upgrade. Select the ROM ZIP.
  3. Follow on-screen prompts. The phone will reboot and apply the update.
  4. If local install fails, try recovery:
    • Power off → hold Volume Down + Power (or the correct key combo) to enter recovery.
    • Choose Apply update from SD card / Apply update from ADB if needed.

Use this first if the package is a stock update ZIP. This preserves IMEI and baseband.

ADB sideload (when package is sideloadable)

  1. On PC install
  2. Enable Developer Options → USB debugging.
  3. Reboot to recovery: adb reboot recovery (or use the device keys).
  4. In recovery choose Apply update from ADB.
  5. From PC: adb sideload filename.zip
  6. Wait for completion, then reboot.

If package is payload.bin (Android factory images)

Some OEM update ZIPs include payload.bin. These usually require:

  • Stock recovery that accepts it (then use local install) OR
  • Tools that can extract payload (there are payload-dumper tools) — more advanced. Preference: try local upgrade first.

If the ROM is for MediaTek (scatter + images) — SP Flash Tool

Only use this if the package includes scatter.txt and *.img files.

  1. Install MTK drivers on PC (VCOM).
  2. Download SP Flash Tool (use the version recommended for your ROM source).
  3. Load scatter.txt in SP Flash Tool, confirm partitions, do not format unless you know what you’re doing.
  4. Choose Download Only to flash images (safer) or Firmware Upgrade for comprehensive flash.
  5. Power off phone, connect via USB when prompted. SP Flash will detect the phone via VCOM and flash.
  6. After success, unplug and boot.

Warning: wrong scatter or options can wipe IMEI/NVRAM.

If device is Qualcomm (EDL/MSM) — factory tool / QPST / MSM Download

Qualcomm phones sometimes require factory tools or EDL mode (EDL flashing can be dangerous if you don’t have the correct programmer files). Only use trusted, device-specific factory tool packages.

Bootloader / Fastboot (when using fastboot images)

If the package contains boot.img, system.img and you intend to flash via fastboot:

  1. Enable Developer Options, OEM unlocking (this wipes data).
  2. Reboot to fastboot: adb reboot bootloader
  3. Check device: fastboot devices
  4. Example commands:
    • fastboot flash boot boot.img
    • fastboot flash system system.img (if sparse images, you may need fastboot flash --slot=all system system.img)
    • fastboot reboot

Important: Unlocking the bootloader (fastboot oem unlock / fastboot flashing unlock) will factory reset the device and may void warranty.

Post-flash checks

  1. First boot may take several minutes — be patient.
  2. Verify IMEI and baseband: Settings → About → Status — ensure IMEI exists. If IMEI is missing, stop and seek expert help (restoration of EFS/NVRAM is required).
  3. Verify network, Wi-Fi, camera etc.

If you get errors / phone stuck in bootloop

  1. Try wiping cache and a factory reset from recovery.
  2. If stuck in bootloop after modifying partitions, restore the original full stock package (the same exact ROM).
  3. If IMEI lost, do not attempt random tools online — ask for step-by-step help with logs and exact package contents.

Where to get official stock ROMs (safe sources)

  • Official Realme Support site / downloads — always preferred.
  • Realme community forums — official or trusted partner posts.
  • XDA Developers (device-specific subforum) — community builds and guidance.
  • Avoid random file-hosters with unknown reputations.

Quick checklist you can paste to me

If you want me to give exact commands for your file, paste the exact filename and the list of top-level files inside the ZIP (you can paste the output of ls -1 or the list shown by your file manager). I’ll tell you which flashing method to use and give the exact commands for ADB/fastboot/SP Flash as appropriate.

If you prefer, paste the filename or the top-level file list from inside your ZIP now and I’ll map it to the exact flashing method and commands.
