QuantStudio™ 3 Real-Time PCR System, MiniAmp™ Plus Thermal Cycler, and Qubit Fluorometer Package - FAQs

You can perform this action if you have access to an Admin account on the QuantStudio instrument and if it is compatible for the downgrade (newer instruments are not compatible with v1.3.3). If your instrument serial number is below the following, then it can be downgraded:
QuantStudio 5 96-well, 0.1 mL block - SN 272514140
QuantStudio 5 96-well, 0.2 mL block - SN 2725210507
QuantStudio 5 384 well block - SN 272533285
Please also check if the instrument is being used with any validated protocols that may require a particular firmware version to be compliant. If you need the firmware itself, you can download it here.
The instructions to downgrade the firmware are on p.4 of the Release Notes: QuantStudioTM 3 & 5 Touchscreen Instrument Operating Software Version 1.3.3. It's the same process as an upgrade.

If the admin PIN has not been changed, 1234 should work. If it does not work, you can also try 0000.
However, if the admin PIN has been changed and none of the above PINs work, follow the instructions in the QuantStudio 3 and 5 Real-Time PCR Systems manual, page 100.
