Hello,
I am reaching out regarding an inquiry about the firmware for the EC25-E Mini PCIe LTE module.
Our company currently owns an EC25-E Mini PCIe module(Firmware: EC25EFAR06A21M4G, R06 Version).
To operate this module on Korean mobile network operators, Certified Firmware is required.
However, according to Quectel Korea’s response, the only firmware certified by Korean operators is the R08 version (e.g.,EC25EFAR08A04M4G_KR_01.001.01.001).
Quectel also informed us that **cross-downloading between R06 and R08 firmware is not supported, and attempting to do so may cause the module to malfunction
So I would appreciate your support regarding the following:
How to upgrade the R06 firmware to the R08 version,
How to purchase an EC25-E Mini PCIe module with the R08 firmware pre-installed,
Or if you have any other possible solutions, please let me know.
Thank you for reaching out and for the detailed information about your EC25-E Mini PCIe module.
Regarding your questions:
1.Upgrade from R06 to R08 firmware
As informed by Quectel Korea, cross-downloading between the R06 firmware (EC25EFAR06A21M4G) and the R08 firmware (e.g. EC25EFAR08A04M4G_KR_01.001.01.001) is not supported. Due to this limitation, there is no safe procedure to upgrade an R06 module to the R08 firmware. Attempting to do so may cause the module to malfunction, so we do not recommend or support this operation.
2.Purchasing EC25-E Mini PCIe with R08 firmware pre-installed
For operation on Korean mobile network operators, we recommend using EC25-E Mini PCIe modules with the Korea-certified R08 firmware pre-loaded. You can purchase these modules through our local sales channel/distributor.
Kindly share your expected volume and project schedule, we can help connect you with the appropriate Quectel sales contact to supply EC25-E Mini PCIe modules with R08 firmware from the factory. kindly reach out to me on this via mai, we will do our best to support you.
Best regards,
Aghelan
