#unknown hacker who modded a cheap flip phone's firmware where are you

Samsung SGH-X427m and X507 dumped, plus a modified SPH-M270 firmware shipping on a prepaid carrier device..?

I know posting has been slow, but rest assured phone preservation has shown no signs of slowing down!

Some new firmware dumps as of late:

Samsung SGH-X427m, version X47MUCDI3 (incomplete; 8 of 16MB)

Samsung SGH-X507, version X507UCFC2. A previously undumped model!

Samsung SPH-M270, version FA10 on Virgin Mobile. Read on for the story of the previous FA10 dump…

The previous Samsung SPH-M270 dump was done on an unsuspecting device with a Q Link Wireless sticker on it, and appeared to be based on an existing Virgin Mobile firmware, itself still having some Sprint remains. It wasn't put into question until the phone in question had much less restrictions compared to any Virgin Mobile feature phone, including a working Qualcomm Diagnostic port as well as working test dial codes (such as the ##2739# BREW code). When known BREW contributor kraze1984 picked up his own M270, he noted that none of the dial codes which worked on the Q Link device worked on his, and that it only allowed for an MTP connection when plugged into a PC. One JTAG dump later, and it was found that every single mention of Virgin Mobile was replaced with "Phone", resulting in the phrase "You may need to contact Phone" being found on the modified firmware. It is yet to be known who made the modifications to the M270 firmware for Q Link Wireless, or why they even bothered to do such…

Last but certainly not least, thank you to MC4f for the recent donations and krzbrew for dumping the stock SPH-M270! I hope to be able to share info on a very interesting reference device soon…
