I'll report back soon.

OK I reentered the first line of the ADB command with same read only response so I did ADB remount and got 'remount successful', but when I ran the command again I got the same response 'failed to copy.... 'File system is read only'. My device is being recognized. I'm open for suggestons. Please don't steer me wrong I want to be able to use this thing. Thanks

A temporary fix for this is go to root explorer and mount system as r/w

Try:

adb shell busybox mount -o remount,rw /

Might have to install busybox, but I assume the root kernel installs it automatically.

Edit - And if it doesn't work, it just won't do anything, it won't hurt your phone.

ok, it accepted all commands. Now do I need to type in sopmething before I exit ADB. I am leaving the command prompt open in case I do. Thanks

If you typed in all the commands he listed and got no errors you should be done.

I would do "ADB reboot" to reboot and then give it a try.

i dd'd the modem. it gave me no signal... circle with line thru it...
i got no errors.. i pushed the bin files to sd card and dd'd them from root shell. all successful but no signal....

commands i used:
adb push mdm.bin /sdcard/
adb push amss.bin /sdcard/

adb shell


dd if=/sdcard/mdm.bin of=/dev/block/mmcblk0p13
dd if=/sdcard/amss.bin of=/dev/block/mmcblk0p17

okay ADB was successful, however my phone was acting up and kept rebooting. I reflashed the at&t modem with Odin. I flashed the t mobile modem again through ADB successfully with the same results. I reflashed the at&t modem again through Odin. then I tried the method that kc720 used in post #15 with the same results. Now I'm back on the default at&t modem again. I am using an active t mobile sim card. If I can get the t mobile modem to stick I can then dial *#2263# and attempt to use the wcdma 1700 band that does show up with my t mobile sim card though when I try to use it with the at&t modem I just get the circle with the line through it where my bars should be. Hope this helps. I really want the 1700 frequency to work and ready to try something else
