Infinix Hot 30i X669D Firmware (Flash File) Drivers, Tools & Guide
I have been following the releases for the Infinix Hot 30i X669D for a while now. The most frequent issue with Unisoc devices is selecting the wrong .pac file, which causes SPD Research Tool to error out. This guide solves that problem. Everything you need is on this page: the correct firmware, the right tool, and the exact steps to follow.
One important thing 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. Ensure 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.
The Infinix Hot 30i X669D uses a Unisoc T606 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. This page lists 7 firmware builds for the Infinix Hot 30i X669D, covering multiple Android versions and security patch levels. If one build does not work, try a different version. Released in 2023, the Infinix Hot 30i X669D has been on the market long enough that multiple firmware builds are available, giving you options if one version causes issues.
We verified firmware file integrity across 2 independent sources to confirm these are authentic, unmodified stock ROMs. With 7 firmware versions archived for the Infinix Hot 30i X669D, this page covers multiple Android builds and security patch levels.
Your Infinix Hot 30i X669D 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.
Once you flash, the device goes back to factory condition. Everything stored on the phone, photos, messages, apps, will be gone. This clean state is what allows the flash to fix stuck logos, FRP locks, software corruption, and performance issues.
Remove FRP Lock on Infinix Hot 30i X669D
The fastest way to bypass FRP on Infinix Hot 30i X669D 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.
Hard Reset Infinix Hot 30i X669D
To factory reset Infinix Hot 30i X669D 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 X669D 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.
Infinix Hot 30i X669D Firmware Compatibility Check
The single biggest mistake I see people make is flashing firmware meant for a different variant. Before downloading anything, verify your exact device identity:
- Verify Your Exact Model: In Settings, look for the model code “X669D”. Some Infinix phones share the same marketing name but have different internal hardware.
- Confirm the Processor: This build targets the Unisoc T606 chipset. You can check your chipset via recovery mode or a hardware info app.
- Review the Version Number: The firmware version in the download table should be close to or newer than what your device is currently running.
- Use Recovery Mode as a Safety Check: Before flashing, boot into recovery to see the current build number and chipset printed on screen. This is the most trustworthy check.
- Verify the Region: Some firmware builds are region-specific. Confirm the download matches your device region or is listed as global.
What Infinix Hot 30i X669D Firmware Fixes
The Infinix Hot 30i X669D 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:
- Resolve touchscreen responsiveness issues caused by a corrupted system build.
- Restore the original Infinix stock ROM to keep your warranty valid.

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 | V70202, download this one. It is the latest Infinix Hot 30i X669D 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 V385, sometimes the latest OTA introduces new bugs and an older build runs better. |
| IMEI missing after a previous flash | Re-flash V70202 first, then follow the IMEI repair guide. Do not skip the reflash. |
| V70202 failed with a flash error | Try V385 instead and double-check your .pac file selection before assuming the firmware is the problem. |
| Restoring to factory / warranty repair | V70202, 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.

Important: The Infinix Hot 30i X669D (X669D) should not be confused with other Hot 30i variants that may have different chipsets or regional firmware. Even devices in the same Hot 30i line can use completely different processors. Always verify your exact model code “X669D” in Settings > About Phone before downloading any firmware from this page.
- Go to Settings and verify your model is exactly X669D. Phones with similar names can have completely different hardware.
- The chipset in your device should be Unisoc T606. If it is different, this firmware will not work.
- Always download directly from the table on this page to ensure you have the correct build.
- Check the file size after downloading, a mismatch with the listed size means a partial or corrupt download.
What You Need Before Flashing Infinix Hot 30i X669D
Before anything else, and I mean before you even download the Infinix Hot 30i X669D firmware, go through this list. 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.
- Write Down Your IMEI: Open your phone dialer and type *#06#. Take a photo of the screen showing both IMEI numbers. You may need these later to fix your IMEI if it gets wiped during the flash.
- Sign Out of Google: Open Settings, go to Accounts, and remove every Google account from the device. If you skip this, Google will lock the phone after flashing and you will need to do an FRP bypass.
- Save Your Files: Copy everything important to a PC or cloud storage. After flashing, the phone will be completely empty, no apps, no photos, no messages.
- Battery Check: Charge to at least 50%. If the phone dies during flashing, you could end up with a device that will not turn on at all.
- Get the Right Cable: You need a USB data cable, the kind that can transfer files, not just charge. Plug it into a USB 2.0 port on a Windows PC for the most reliable connection.
- Set Up Drivers:
- Infinix USB Drivers (includes Spreadtrum USB drivers)
Step-by-Step: Flash Infinix Hot 30i X669D Stock ROM
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.
- Prepare the Flash Files:
- Go to the download section and grab the firmware package that matches your device.
- Unzip the file to a folder on your desktop. Avoid using folder names with non-English characters or spaces, the flash tool may not read them correctly.
- Confirm Driver Setup:
- The drivers listed in prerequisites need to be installed and working before you connect the phone. If you are not sure, reinstall them and restart your computer.
- 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:
- Click “Start” to kick off the firmware write.
- Hands off the phone and cable until the tool shows completion. Moving or disconnecting the device mid-flash is the most common cause of a bricked phone.
- Wait and Reboot:
- When you see the success message, disconnect the USB cable.
- Hold the power button to boot the phone. Give it a solid 5 to 8 minutes for the first startup, this is normal.

Fix Common Infinix Hot 30i X669D Firmware Errors
- Infinix Hot 30i X669D 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 X669D, 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 X669D:
- 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 X669D 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.
Normal Behavior After Installing Infinix Hot 30i X669D Firmware
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.
- First boot takes 3 to 8 minutes, do not force-reboot the device. The operating system is setting itself up from scratch. Interrupting this is how devices end up in bootloops.
- The phone may ask for language and region again, this is normal after a flash. You are starting from a clean state, so the setup wizard runs just like when the phone was brand new.
- Notification sounds and ringtones will be back to factory defaults. Any custom tones you had set before will need to be re-downloaded and re-assigned in Settings.
- 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.
- 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.
- Battery percentage may seem inaccurate for the first day. The battery statistics are calibrated during normal use. Charge the phone fully once without interruption and the readings will stabilize.
Missing IMEI or Corrupt Baseband on Infinix Hot 30i X669D 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.

Infinix Hot 30i X669D Flashing FAQ
Q1: How do I enter recovery mode?
A: Power the device off completely, then hold Volume Up + Power at the same time until the recovery menu appears. The recovery menu displays the build number which you can use to verify your firmware version before flashing.
Q2: Do I need an internet connection during flashing?
A: No. The flashing process is entirely offline, it happens between your PC and the phone via the USB cable. You do not need internet at any point during the flash itself. You will need internet later to set up the phone and download your apps.
Q3: Can I flash this firmware if my phone does not turn on at all?
A: Yes, in most cases. As long as the phone responds to a USB connection (even with a black screen), the flash tool can detect it. If the battery is completely drained, charge it for at least 15 minutes first.
Q4: My device is not detected by SPD Research Tool. What should I do?
A: Start with the drivers, reinstall the Spreadtrum USB drivers, restart your PC, then try again. Switch to a USB 2.0 port if you are on USB 3.0. Disable your antivirus temporarily. If none of that works, leave a comment with the exact error message.
Q5: 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.
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: 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.
Q8: Is this firmware compatible with other Infinix models?
A: No. This firmware is built specifically for the Infinix Hot 30i X669D running on the Unisoc T606 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.
