Hello all, This is my first time on this forum and decided jump in after reading the B153 bashing. Granted that the company deserves a lot of the complaints and disgruntled customers (mainly due to its amazing support ) But I do have to say I love the player itself (mainly for it's amazing battery life). Anyways enough of the introduction this fix is for all those firmware problems system errors and the lot. I personally had a problem in which my computer recognized the player as a USB device and would not boot.
The trick is MobiBLU has ok support.... just mainly for it's Korean customers so you're gonna have to download off their Korean site (this file is nowhere to be found on the American site though it is mentioned once in their FAQ)
and click on DAH-1900_Updater_M110_060424.exe
what you're downloading is pretty much a BIOS Flasher for your player.
once downloaded go ahead and start the program, It should automatically install and leave a desktop Icon. open up the program which consists of a simple ext box and button labeled Initialize. connect your player to your PC and go ahead to click the initialize button.
after about half a minute it should finish reflashing. disconnect your player and see if it turns on properly. If it does I'd reccomend updating the firmware immediately which is fairly simple. download http://www.mobibluamerica.com/downloads/B1.../B153_M1.10.zip unzip and simply move the BIN file over to the root directory of your player!
hope this solves a lot of problems!
If this doesn't work go ahead and ask me (I enjoy a challenge) I'll try to answer your questions as best as I can
