Q1. The tool is stuck on "Checking Baudrate." How do I fix this?

This is the most common issue with the SPD Upgrade Tool. It means the tool cannot communicate with the phone. The cause is almost always an incorrect driver installation or not using the correct boot key. Re-install the drivers and make sure you are pressing and holding the Volume Down key *before* connecting the phone.

Q2. Can I use SP Flash Tool or QFIL for this phone?

No. SP Flash Tool is for MediaTek (MTK) chipsets, and QFIL is for Qualcomm chipsets. The Advan i5E uses a Spreadtrum (SPD) chipset, so you must use the SPD Upgrade Tool or a similar tool like ResearchDownload.

Q3. My IMEI is null or zero after flashing. How can I restore it?

Losing the IMEI is a common risk when flashing Spreadtrum devices. This firmware flash will not restore it. You will need a separate SPD IMEI tool to write your original IMEI numbers back onto the device. The original numbers are printed on a sticker found under the phone's battery.

Advan i5E Stock Firmware (.pac File for SPD Tool)

The Advan i5E is a 5-inch 4G LTE smartphone from the Indonesian brand Advan, released in 2017. It was marketed for its “Glassy Design” and solid performance for its price point. If your Advan i5E is bricked, stuck in a bootloop, or suffering from severe software errors, flashing the official stock firmware is the definitive way to restore it to its factory condition.

Important Note: This device is powered by a Spreadtrum (now UNISOC) chipset. The flashing process requires the SPD Upgrade Tool and a `.pac` firmware file. This process will erase all your personal data.

🔧 Device-Specific Troubleshooting

Phone Not Detected by PC: The removable battery is helpful here. Ensure the phone is off by removing and re-inserting the battery. Hold the boot key (Volume Down is standard, but some variants might use Volume Up) firmly *before* you plug in the USB cable. If it’s still not detected, the issue is with the SCI USB Drivers on your PC.
“Operation Failed” Error during Flashing: If the process starts but then fails, it could be due to an unstable connection. Try a different USB port (preferably a USB 2.0 port) and a high-quality cable. A corrupted .pac file can also cause this, so try downloading the firmware again.
Upside-Down Screen or Wrong Colors After Flash: This indicates a hardware mismatch, usually with the display panel. The Advan i5E may have been released with slightly different screen components. This V0.3 firmware might be for a different revision than your specific phone. You would need to find the exact firmware version that matches your device.
Stuck on Advan Logo After “Passed” Message: If the flash was successful but the phone doesn’t boot, you need to clear the old data. Boot into recovery mode (usually Power + Volume Up), and from the menu, select “wipe data/factory reset” and confirm. This will allow the new system to boot properly.
