That Audiovox CDM-8930 Prototype Board

This might be a pretty lengthy read since this was originally written for Twitter/mastodon thread bursts but... here goes!

As promised, here's a post about the prototype Audiovox CDM-8930 that was recently uncovered.

The phone board was originally posted for sale without any indication of who made it, though there were a few clues that it was at least a Curitel-made ODM. For context, the vast majority of Audiovox phones made in the early-mid 2000s were ODMs from Curitel (later Pantech).

So what clues were there? The listing photos weren't clear enough to make out any board markings, though the phone came with a box with HYUNDAI and "TX-125C" on it. Hyundai had a mobile phone division at a point, which would then go on to be purchased by Curitel.

The "TX-125C" marking also helped narrow it down a lot - it was very close to other released Audiovox phone FCC IDs (e.g. CDM-8920 → PP4TX-120C → TX-120C). What was odd about this was that there is no TX-125C registered with the FCC…

Skipping ahead to acquiring the phone board, the oddities only increased. The board itself did not have the TX-125C markings, but instead had "TX130C_MAIN PROTO1_4_A 2003_09_17 T130M_03_335" silkscreened around the top right. The question then became "was there a TX-130C FCC ID?"

There sure was. It turns out this board strapped to a piece of cardboard with twisty ties was a prototype of the #Audiovox CDM-8930 - a phone that is not too frequently found for sale online. (photo courtesy of the user manual) https://fccid.io/PP4TX-130C

The silkscreened date on the board helped show how early of a prototype this was - almost half a year before its FCC approval! Unfortunately without a screen, it was hard to say what sort of software was on it (if there was anything on it at all).

The only indication that it wasn't completely blank at that point was the fact its power draw wasn't entirely consistent, though it did loop around the 120-130mA range. Next up was dumping the phone via JTAG, as per usual around here :)

Dumping the flash chip let us know it was not entirely blank! Checking for common resources using MultiExtractor showed the same sort of icons that could be found on the Qualcomm 6280 F-US reference device that was sent in not too long ago.

From there it didn't take long to realize this was still running bone-stock Qualcomm reference firmware! The latest date referenced was October 27th, 2003, which isn't as early as the board itself, but still predates its release let alone FCC approval by quite a bit. It identified itself as "T130CVE0R01.152"

While the Hyundai box nor the included JTAG adapter were used to dump the firmware, they will certainly be held onto. Oddly enough, the TTA-24 plug with the parallel port end does not have all 24 wires connected, despite having more than enough pins available on said port.

It would certainly be interesting to try and flash this to a retail CDM-8930 - but not before preserving a retail firmware release first!

Virgin Mobile Audiovox CDM-8610 dumped

Another day, another phone firmware archived! This is the Audiovox CDM-8610, more specifically the Virgin Mobile branded variant. VM phones are notorious for being very locked down, but they fortunately did not disable the JTAG test points. Download here: https://mega.nz/folder/2aoVnJJJ#ovZJG4cbvIOqLVEJBHrQSQ/folder/LPomDKxY
