  1. Hi Toanhung, Thank you for sharing the pinout. Would you please advise which JTAG cable and software are you using? I have built my own Wiggler parallel port cable and tested with OpenOCD software. However, there is no response from my i600 even I have pulled-up either TMS or TCK. Accidentally, I found that the i600 would NOT automatic power off if I pulled-up TMS so that I can run some program from the MicroSD card. But there is NO radio at all and NO USB can be connected. Is there any software like SSPL to load firmware / bootloader from Windows Mobile 6 OS? Thanks, Martin Wong
  2. Dear All, Rather than using the previous RS232 cable, there is also another HOPE to reflash the phone. It's JTAG. I have disassembled my SGH-i600 finally to find out the JTAG pins, but I still can't. Please find the attached photos for your reference. However, I got an array of 4x4 test points without any labelling from the PCB. Can anyone share me the pin out of these JTAG test points? Which one is TD1, TD0, TCK, TMS and GND? BR, Martin Wong
  3. This Cable! I am looking for it. See the picture in the attachment.
  4. FEEL FREE TO TRY!! For people who has flashed i600 with i607 ROM (1) Use a samsung D820 cable with Serial Port and plug into your i600 (2) Connect the cable to your PC's serial port (probably COM1) (3) Install the Samsung Blackjack Modem Driver (4) Uncheck the "Allow USB connections" in Active Sync option and select COM1 in "Allow connections in one of the followings" (5) Let Active Sync to search for the i600 and wait for "Connected" (6) Run the i600 firmware update program as usual. P.S. please let me know the result.
  5. Hi All, For my i600 which has flashed with i607 rom, actually I won't able to use its user interface within the OS, because it will power off automatically and I cannot prevent it to auto power off. Will there any key combination to stop it auto power off? I heard that there is a debuy mode on it. By pressing "Power" + "Left soft key" + "Camera" keys to launch the debug mode. It will prompt to press 0 or Space to enter configuration. Do you know how to make use of this debug mode to save the phone? Thank you very very much!!! Best Regards, Martin Wong
  6. HELLO EVERYONE :rolleyes: , I have got the same problem after flashing my i600 with i607 ROM, but I think if we can change the bootloader from Xcingular 1.2 back to Open 1.1 that will solve the problem. Is there any method to boot the machine from Micro-SD even without USB connection? Is there any special key to trigger it boot from Micro-SD? Secondly, my phone still booting to show the AT&T logo and then shows "GoodBye" and Power Off. Sometimes, it shows the "Start" button for a while before it powers off automatically. Can I use some key to avoid it auto power off and let me to do something inside the windows mobile OS? Thanks, Martin
