How to Roll Back Firmware on Epson L15150 Printers

Question:
I watched your video about downgrading firmware and fixing incompatible cartridge errors on the Epson Artisan 1430. I have an Epson L15150-how can I roll back the firmware update on this model?

Answer:

1. Restart in Service Mode and Use Recovery Firmware

The first method is to restart your Epson L15150 in service mode and then run Epson's recovery firmware tool. This overwrites the currently installed firmware and restores compatibility with cartridges that may have stopped working after an update. Epson releases these tools occasionally, and they are usually distributed to service centers, though you may find them through online support communities or third-party sellers.

2. Using WICReset Software

If the recovery firmware option doesn't resolve the issue, you can try the WICReset utility. This software allows you to roll back to a previous firmware version, provided that the rollback version is still available. You can find it at wic.support or other authorized resellers. WICReset is widely used for Epson printers, especially when cartridge recognition problems appear after an update.

3. EEPROM Dump Method (Advanced)

If the printer's EEPROM firmware is corrupted or cannot be reset through software, a more advanced approach may be needed:

• Search for a binary dump file (bin dump) for the Epson L15150. You can sometimes locate these files by searching online with the model number.

• Use an EEPROM programmer-you can either build one yourself or buy a ready-made device from Amazon. This lets you physically write the bin dump into the memory chip.

• In severe cases, the EEPROM memory chip itself may need to be replaced if it is no longer holding stable firmware data.

4. Important Notes

• Always ensure you are using the correct firmware or bin dump file for your exact printer model, as using the wrong version can permanently brick the device.

• Be cautious with third-party software or firmware downloads-only use trusted sources.

• If your printer still shows cartridge errors even after firmware rollback, you may also be dealing with a chip recognition or CSIC board issue, so it's worth keeping that possibility in mind.

Addressing firmware rollback issues is highly technical and often requires hands-on work. For this reason, we can't provide remote support or troubleshooting for this type of repair. However, we do provide an in-person printer repair service (https://bchtechnologies.com/printer-repair-service). Since we operate on a first-come, first-served basis and demand is high, wait times may be a few weeks. If you prefer self-help, I recommend searching our YouTube channel (https://youtube.com/@bchtechnologies) using the search icon near the "About" tab to find firmware-related videos.
