How to Flash the Firmware: 5 Key Points
This is a high-level overview of the flashing process using SP Flash Tool. For a full, safe, and detailed guide, you must click through to our main pillar article linked below.
- Prepare Your PC: Download and install the required MediaTek VCOM USB drivers to ensure your computer can communicate with your phone.
- Load the Firmware: Launch SP Flash Tool and load the firmware by selecting the `…scatter.txt` file from the extracted firmware folder (e.g.,
BQ_Bliss_5511L_MT6737M...zip). - Configure the Tool: Ensure the flashing mode is set to “Download Only.” This is the safest option and helps prevent the loss of your phone’s IMEI number.
- Initiate the Flash: Power off your phone completely and remove the battery. Click the large “Download” button within the SP Flash Tool to set it to standby.
- Connect Your Device: With the battery still out, immediately connect your phone to the PC with a USB cable to begin the flashing process, which finishes when a green “OK” checkmark appears.

Troubleshooting Common Issues
1. “Storage Space Running Out” Warning
Cause: The BQ-5511L Bliss has only 8GB of internal storage, of which the Android system uses nearly 5GB. This leaves very little room for apps and user data, causing this warning to appear quickly.
Solution: A microSD card is essential for this device. Set it as the default write disk if possible. Use “Lite” versions of apps (Facebook Lite, Messenger Lite) and regularly clear the cache of all applications via Settings > Storage.
2. SP Flash Tool BROM ERROR 4032: S_FT_ENABLE_DRAM_FAIL
Cause: This common error on older MediaTek devices often indicates an issue with the driver, the SP Flash Tool version, or the connection timing. It means the tool failed to communicate with the phone’s memory.
Solution: Ensure you have installed the correct VCOM drivers. Try using a slightly older version of SP Flash Tool (like v5.18xx). The most common fix is to click “Download,” then connect the phone with the battery REMOVED. Only insert the battery after the red progress bar appears.
3. Invalid IMEI After Flashing
Cause: This critical issue occurs if the NVRAM partition is erased, usually by selecting the “Format All + Download” option in SP Flash Tool.
Solution: To avoid this, ALWAYS use “Download Only” mode. If your IMEI is already lost, you will need an advanced tool like Maui META to manually rewrite the original IMEI numbers, which can be found on a sticker in the battery compartment of your BQ-5511L Bliss.
Frequently Asked Questions (FAQs)
- Can I upgrade the BQ-5511L Bliss to a newer Android version?
- No. The official firmware provided, Android 7.0 Nougat, is the final major software version released for this device. There are no official updates to Android 8 or newer for the BQ-5511L Bliss.
- Will flashing this ROM remove the Google FRP lock?
- In most cases, yes. A full firmware flash with SP Flash Tool typically overwrites the partition that stores the Factory Reset Protection (FRP) lock. However, some stubborn locks may require a manual format of the FRP address using the tool’s “Format” tab.
- Why is my phone so slow, even after a fresh flash?
- The BQ-5511L Bliss has very modest hardware (1GB of RAM). Even a fresh installation of Android 7.0 will struggle with modern applications. For the best performance, disable animations in Developer Options and only install essential, lightweight apps.
- Is the battery for this phone removable?
- Yes, one of the features of this model is its user-removable 2500 mAh battery. This can be helpful for forcing a hard reboot if the device freezes.
Conclusion
Restoring your BQ-5511L Bliss with its official stock firmware is the definitive solution for overcoming software problems and restoring the device’s original performance. By using SP Flash Tool correctly and following the detailed instructions in our main pillar guide, you can successfully unbrick your phone. Always back up your data first and use the “Download Only” mode for a safe flash.
