That's a lie.
You can't brick your modem at all, as it has a ROM bootloader.
Dedicated person can damage calibration data and that'd be a
practically irrecoverable action (CMU-2000 and special soft are needed
for calibration). BUT it's not as simple as making a typo.
Damaging one's modem by typo is practically impossible, moreover, the
new moko11 firmware contains quite an important fixes related to
hardware flow control and resuming from call/sms. As it also fixes all
known issues with any sim cards, it's worth updating.
Thanks Paul,
I'm trying to flash my GSM firmware and running into a problem.
I get to the point where I run the fluid command line and it just
sits there.
Here are the steps I'm taking for doing the flashing. I'm following
the docs on the wiki
at:
http://wiki.openmoko.org/wiki/GSM/Flashing.
After I get the
Bootloader: (reset target)
message, I run s3c24xx-gpio b7=1 in another xterm, ssh'ed into the FR.
and the main window just sits there.
Here's the output of what I'm typing in the main window:

Help ?
How long should I wait for the Bootloader to respond to the s3c24xx-
gpio b7=1 command ?
The documentation makes it sound like it should happen right away.
Thanks,
