Infinix Hot 30i X669 Firmware (Flash File) Drivers, Tools & Guide
This page provides the official Infinix Hot 30i X669 firmware, necessary drivers, and step-by-step instructions to restore your device to working condition. We cover unbricking, bypassing FRP, and performing a clean reflash.
The Unisoc T606 is a capable processor, but these phones can still run into software trouble. One thing I have learned working with Unisoc devices is that the most common headache is not the flashing process itself, it is selecting the wrong .pac file and then wondering why SPD Research Tool throws an error. This guide is here to fix that. Everything you need is on this page: the right firmware, the right tool, and the exact steps to follow.
One important detail before you start: the firmware package for Unisoc devices is a single .pac file, not a folder of separate partitions like you would see with MediaTek. Make sure your downloaded ZIP actually contains that .pac file before you open the flash tool. A lot of time gets wasted loading an empty or partially downloaded archive.
This page lists 7 firmware builds for the Infinix Hot 30i X669, covering multiple Android versions and security patch levels. If one build does not work, try a different version. The stock firmware ships with Android 12, XOS 10.6, which determines the default apps, security features, and interface you will see after flashing. The Infinix Hot 30i X669 uses a Unisoc T606 (12 nm) chipset (Unisoc/Spreadtrum), so you will need SPD Flash Tool and SPD USB drivers. These tools are specific to Unisoc-based devices and will not work with MediaTek or Qualcomm phones.
The Infinix Hot 30i X669 was released in 2023. This page is maintained with the latest available firmware builds as they become available. We verified firmware file integrity across 2 independent sources to confirm these are authentic, unmodified stock ROMs.
Your Infinix Hot 30i X669 firmware comes as a compressed ZIP file. Download and extract it using WinRAR or 7-Zip. Once extracted, open the folder and confirm it contains the .pac file before proceeding.
A full flash will erase everything on the device: apps, accounts, photos, and settings. That is the point, it gives you a clean slate and resolves issues like screen locks, FRP prompts, dead boot states, sluggish performance, and connectivity problems.
Hard Reset Infinix Hot 30i X669
To factory reset Infinix Hot 30i X669 without a computer, power off the device completely, then hold Volume Up and Power at the same time until the recovery menu appears. Use the volume keys to navigate to “Wipe Data/Factory Reset” and confirm with the Power button.
A hard reset erases all data and restores Infinix Hot 30i X669 to its original factory state. This fixes most software problems, slow performance, app crashes, forgotten screen locks, and bootloops. If the issue persists after a factory reset, a full firmware flash using SPD Research Tool is covered in the following sections.
FRP Removal for Infinix Hot 30i X669
The fastest way to bypass FRP on Infinix Hot 30i X669 is to use a free Android apps launcher that lets you access settings during the setup wizard. After flashing or performing a factory reset you may see a Google account lock (FRP). Our free Android apps launcher is the fastest way to get past it. This is also why I always recommend removing your Google account before flashing, it avoids this problem entirely.
Why Flash Stock ROM on Infinix Hot 30i X669?
The Infinix Hot 30i X669 runs on a Unisoc (Spreadtrum) chipset, and the most reliable way to fix software issues on these devices is a clean firmware flash using SPD Research Tool. Here is what the stock firmware can fix:
- Unlock your device if it has been locked or disabled.
- Resolve touchscreen responsiveness issues caused by a corrupted system build.
- Fix Wi-Fi, Bluetooth, or mobile data connectivity that stopped working after an update.
- Repair a phone that shuts down randomly or restarts in a loop.
- Resolve OTA update failures and battery drain issues.
- Fix startup loops, lagging, and freezing on your device.
- Resolve .pac loading failures and communication errors in SPD Research Tool that prevent normal use of your device.
Learn more about stock ROMs and why flashing works.
Choosing the Right Firmware Version
The single biggest mistake I see people make is flashing firmware meant for a different variant. Before downloading anything, verify your exact device identity:
- Open About Phone: Your device model must read “X669” exactly. Even small differences in the code can mean a completely different chipset and partition layout.
- Verify the Chipset Type: This firmware targets Unisoc T606 (12 nm) specifically. Flashing it on a different chipset will fail or could brick the device.
- Check Your Current Firmware Version: Compare your build number with the versions listed in the download section to decide which file to use.
- Use Recovery Mode: If you cannot access Settings (phone is stuck or locked), boot into recovery mode to read the build and chipset details from the screen.
- Regional Compatibility: Some Infinix firmware packages target specific regions. Confirm the download matches your device origin.

Which Firmware Version Should I Download?
This is the question I get asked most often in the comments, so I put together a simple guide. Find your situation in the table and go straight to the right file:
| Your Situation | What I Recommend |
|---|---|
| Phone is completely dead or stuck on logo | V20240408, download this one. It is the latest Infinix Hot 30i X669 firmware available. |
| FRP / Google account lock only | See the FRP bypass guide above, you likely do not need the full firmware for this. |
| Phone slow after a recent OTA update | Try V541, sometimes the latest OTA introduces new bugs and an older build runs better. |
| IMEI missing after a previous flash | Re-flash V20240408 first, then follow the IMEI repair guide. Do not skip the reflash. |
| V20240408 failed with a flash error | Try V541 instead and double-check your .pac file selection before assuming the firmware is the problem. |
| Restoring to factory / warranty repair | V20240408, clean state, fresh start. |
With Unisoc devices, I recommend using the latest .pac file first. Older versions of the SPD Research Tool firmware can sometimes cause modem issues, which show up as no signal after flashing. Only try an older version if the latest one does not work for you.

Infinix Hot 30i X669 Flash Setup Checklist
Before you start flashing the Infinix Hot 30i X669, you need to check a few things on your PC and device. The most common reason Infinix Unisoc flashes fail is skipping the driver installation step. SPD Research Tool is very particular about drivers, and Windows will not always tell you when they are missing.
- Back Up IMEI Numbers: Dial *#06# and write down both IMEI numbers now. You will need these if you need to restore your IMEI after flashing.
- Remove Google Accounts: Sign out of all Google accounts to prevent FRP lock after flashing.
- Back Up Your Data: Back up everything, photos, contacts, WhatsApp chats, important files. Flashing wipes the device completely.
- Charge Your Device: At least 50% battery. A device that powers off during a flash is very difficult to recover.
- USB Cable & PC: Use a proper data USB cable, not a charge-only cable, and a Windows computer with available USB ports.
- Install Required Drivers:
- Infinix USB Drivers (includes Spreadtrum USB drivers)
Flashing Infinix Hot 30i X669 Firmware With SPD Research Tool
We are using the SPD Research Tool for this. It is the standard tool for Unisoc-based devices. One thing I always do: run it as Administrator. Right-click the .exe and choose “Run as administrator.” This prevents a number of permission-related errors. You can also follow the video guide below if you prefer to see the process in action.
- Download and Unpack:
- Pick the correct firmware version from the downloads above and save it to your PC.
- Extract the ZIP file. If the extracted folder contains another ZIP inside, extract that one too. You should end up with the actual firmware files, not another archive.
- Driver Check:
- Double-check that you have installed the required drivers. A missing driver is the most common reason the flash tool cannot detect your phone. Reboot your PC after installing.
- Load the Firmware File:
- Click the “Load Packet” button and navigate to the extracted folder to select the .pac file.
- Connect Your Device:
- Power off your phone completely, not sleep mode, fully off.
- Connect to your PC via USB cable. The flash tool will detect it automatically.
- Start Flashing:
- Start the flash by clicking “Start”.
- Leave everything untouched until completion. Even bumping the USB cable can interrupt the write and cause a failed flash.
- Wait and Reboot:
- The flash is complete when the tool shows a success indicator. Disconnect your phone.
- Turn the phone on. Do not worry if it sits on the boot logo for several minutes, the system is rebuilding itself from scratch.
Video Guide for Flashing
What to Expect After Flashing
Here is what is completely normal after a successful flash:
- How to know the flash was successful: SPD Research Tool will show a green “PASSED” message when the flash is complete. If you see this, you are done.
- The phone will feel warm during first boot, this is normal. It settles after a few minutes once the initial app setup is complete.
- Dial *#06# immediately after setup to check your IMEI. Do this before you insert a SIM card. If it shows “unknown” or “null”, follow the IMEI repair guide below before doing anything else.
- Be careful when re-adding your Google account, if you did not remove it before flashing, you may see an FRP prompt. Add it fresh during the setup wizard, not afterwards through Settings.
- Fingerprint and face unlock data are erased during the flash. You will need to re-register your fingerprints and face data from scratch in the security settings.
- Storage will show almost full capacity available since all your apps and files are gone. The system partition size varies by firmware version but is typically 4 to 8 GB on most devices.
- Wi-Fi, Bluetooth, and mobile data should all work right after setup. If mobile data is not connecting, go to Settings, SIM and Network, and re-enter your APN manually, the flash sometimes clears carrier APN settings.
Common Issues When Flashing Infinix Hot 30i X669
- Infinix Hot 30i X669 Not Recognized by SPD Research Tool:
- In most cases this is a driver issue, not a cable issue. Reinstall the Spreadtrum USB drivers for the X669, restart your PC, then try again.
- If the device is still not detected, try a different USB port, USB 2.0 ports tend to work more reliably with Unisoc devices than USB 3.0.
- Temporarily disable your antivirus software, it can sometimes block the Spreadtrum driver from loading without showing any error.
- Boot Loop After Flashing:
- Enter recovery mode and perform a factory reset. This resolves most post-flash bootloops on Unisoc devices. If recovery mode is also not accessible, reflash the firmware from scratch.
- Wrong .pac File Selected for X669:
- If SPD Research Tool throws an error immediately after you load the file, you have likely selected the wrong firmware. Confirm that the .pac file model code matches your Infinix Hot 30i X669 exactly.
- No Signal After Flashing:
- This usually points to an IMEI issue. Dial *#06#, if it shows null or unknown, follow the IMEI repair guide above before inserting your SIM card.
Missing IMEI or Corrupt Baseband on Infinix Hot 30i X669 After Flashing?
A missing IMEI after a Unisoc flash usually means the NVRAM partition was not written correctly during the flash. This happens more often than it should on SPD devices. The WriteIMEI Tool handles this well for Unisoc. Just make sure you have your original IMEI written down from before you flashed, dial *#06# before starting next time. Without the original number, you cannot restore it properly.
Use WriteIMEI Tool for Unisoc to restore it. The video guide below shows the exact steps.

Questions About Infinix Hot 30i X669 Firmware
Q1: Will flashing erase my data?
A: Yes, flashing with SPD Research Tool restores the device to factory state, including Android 12, XOS 10.6 default settings. All apps, photos, contacts, and accounts will be removed. Back up everything you need before you start. There is no way to recover data once the flash is complete.
Q2: What if the flash fails halfway through?
A: Do not panic and do not disconnect the phone. Close SPD Research Tool, restart it, and try the flash again from the beginning. In most cases, a failed flash just means the process needs to be repeated. The device is usually still detectable by the flash tool even after a failed attempt.
Q3: What should I do if I encounter an FRP lock after flashing?
A: Use our free Android apps launcher. FRP lock activates when a Google account was still signed in before flashing. This is why signing out of your Google account before flashing avoids this issue entirely.
Q4: Is it safe to flash during a power outage risk?
A: It is best to avoid flashing during unstable power conditions. If your PC shuts down during the flash, it can corrupt the write and leave the phone in an unbootable state. If you are in an area with unreliable power, use a laptop with a fully charged battery instead of a desktop.
Q5: Is this firmware compatible with other Infinix models?
A: No. This firmware is built specifically for the Infinix Hot 30i X669 running on the Unisoc T606 (12 nm) chipset. Even variants of the Hot 30i with a different letter suffix can have a completely different chipset inside. Flashing the wrong firmware can leave your phone in a state that is very difficult to recover from. Always check your exact model number in Settings.
Q6: How long does the flashing process take?
A: The actual flash usually takes between 3 and 10 minutes depending on the firmware size and USB connection speed. The first boot after flashing takes another 3 to 8 minutes. Do not interrupt the device during either stage. If the progress bar in SPD Research Tool appears stuck, give it a few more minutes before assuming something went wrong.
Q7: Will flashing void my warranty?
A: Flashing official stock firmware generally does not void your warranty since you are restoring the device to its factory-intended state. However, some manufacturers may flag that the bootloader was unlocked or that the flash counter increased. Check your specific warranty terms with Infinix support if you are concerned.
Q8: Can I use a Mac or Linux computer for this?
A: The tools and drivers referenced on this page are Windows-only. If you are on Mac or Linux, your best option is to use a Windows virtual machine, or borrow a Windows PC for the 10 minutes it takes to complete the flash.
