PIN 5025 unlocks the system settings information.
MMI box appears to be an Andream unit but the precise model designation is not stated in the system information.
CUST Version: B2_V1.1.2
MCU Version:" 20.8.19.23
When deliberately trying to start a software update without a USB drive inserted the system states that a GEMINI_PACK.BIN! file is not present, i.e. this proves that the unit is looking for GEMINI files rather than ISPBOOOT.BIN.
Software tends to be updated for reasons of stability improvements and/or functionality enhancements so I'd like to update the unit if possible, however...
Looking at Post #3...
B2_V1.1.2 is not listed as a software release (B2 releases start at V1.1.5)
V1.1.2 is listed for a "B" model version.
Could someone with real knowledge or experience of the Andream units comment / correct / advise regarding the following :
- Is the software version a more reliable indicator of the model, i.e. in reality I have a B unit even though B2 is stated in the system information ?
- Conversely, is it more likely that it's a B2 unit but running a software version that precedes the earliest version (1.1.5) listed in Post #3 ?
- If I have a B2 unit, and bearing in mind that 1.1.5 is the earliest version available for download in Post #3, does that effectively mean that my unit doesn't have a software upgrade path (because the instructions in Post #3 state that GEMINI files have to be installed sequentially, and versions must not be skipped) ?
- Can CUST and MCU be updated independently (i.e. in any sequence) or, for example, does the MCU have to be updated first ?
Thanks. |
Well, let me go with the easy one first. The MCU can be updated with much less risk, in my experience, even across models B and B2 and brands. May not be true in all cases. Normally doing CUST or MCU first does not matter, but if your MCU and CUST dates have years between them...it may be an issue.
My best guess is that it is a Andream B2 (Version 1). Not aware that anyone flashed a B2 on a B and lived to tell about it...so unlikely, but possible. There is a post referencing "freeozone" who updated to "B2_V1.2.0_t" the same exact CUST and MCU as yours:

More here buried in the pages on that "B2_V1.2.0_t"version and the MCU:

What file was the unit looking for (Gemini or ISPBOOT) when you wanted to update the CUST? And what file was it looking for (Gemini or ISPBOOT) when you wanted to update the MCU?
