Talk:Baseband Commands

i bought an iphone from 2weeks with baseband 02.30.03 and bootlooder 6.2 and i need to unlock it to work with vodafone sim card need you'r help plz find me a sulution to unlock or downgrade my baseband so i can use yellowsn0w

I am having trouble figuring out how to run these commands on my iPhone 4. I mean minicom does not work. I saved and all but it wont let me see what command im typing and it says "offline" in the bottom.
 * You have to remember, minicom hasn't been updated in a while. It's probably not going to work very well with iOS 4+, and pretty much any device after the iPhone 3G... also, sign your talk page comments :) --rdqronos 06:22, 23 July 2011 (MDT)

Well, I tried tty.debug, dlci.baseband.blablabla... amd it didn't seem to work very well. Are there new releases of minicom? Or the source of it? --XiiiX 17:09, 14 August 2011 (MDT)
 * Minicom is an open source project: --pjakuszew 12:45, 15 August 2011 (MDT)
 * The days of  are gone (1.x?).   does not require CommCenter to be shut down, but you have to spam AT[enter] until you get a reply and then issue your command hoping the connection doesn't fail as CommCenter is using the BB pretty much all the time making you unable to connect. Also, the OFFLINE message is normal. --Ryccardo 05:37, 16 August 2011 (MDT)
 * Would shutting down CommCenter help though? Like honestly, if it's that much of an issue, I'll run the command to kill it... Also, if I did kill CC, would I have to spam AT or would one typing of AT do it? --rdqronos 17:00, 16 August 2011 (MDT)
 * According to my experience in 3.x, shutting down CommCenter barely helps yet it's pretty much a requirement. Remember that shutting it down remover Wi-Fi until a reboot, so you have to permanently disable it, reboot until you can't get signal as per the status bar + get the non-visual voicemail indicator (empty badge over Phone icon), try your luck then enable CCenter with . --Ryccardo 16:50, 18 August 2011 (MDT)

One way around this is to install signal iphone app found in cydia:

"...Signal was designed for iOS 4, and contacts /dev/tty.debug in a iOS 4 compatible way, it does this to receive baseband information, one of them being, the exact measurement in dBm. This opens the port to /dev/tty.debug..." (http://applehack23.blogspot.com/2010/09/smscl-on-iphone-4-and-ios-4.html#comments)

I can confirm this works.--JackR1 07:44, 23 September 2011 (MDT)

I have Minicom set to connect to  (if I turn off CommCenter using  ), but it doesn't display anything. I've tried spamming AT with no success. I tested  to see if anything gets displayed, and it does. Anyways, here is a dump of my : And ideas? I don't know what else to try. --Blue Skies (talk) 00:37, 8 February 2013 (UTC)
 * I have no experience with the baseband, but since the 4S there are no more AT commands afaik. The interface has changed completely. That's why planetbeing's Signal app no longer works. The new baseband chips use a different operating system and communication protocol. --http (talk) 08:08, 8 February 2013 (UTC)
