Serial port under sim card

Hi guys.

Heres my first and probably last post

After some toiling over finding what the hell port is under the sim card, I've finally found it. it's /dev/ttyMSM2

You probably all know that but hey, i spent at least half an hour reading through this messy thread to no avail, just messages by zacpod saying he's trying to find it ;)

I found it using the 'android serialport api project' on google code. That plus the arduino IDE serial monitor.

Also, i managed to solder wires on without too much difficulty, and snipped my sim card a little to accomodate them, and all still closes nicely and the sim still works. They go into an £8 RS-232 to USB converter thing from ebay. It's literally just the famous FTDI chip, 2 leds and a usb plug on a pcb :)

anyway, have fun with this port.

sorry to hijack..

My nephew has an lg gw620r on rogers which is pay as you go. He doesn't have a data plan and when i enable wifi on the phone to get to the market it of course asks for a google account. i created one for him but it keeps saying ".. or our sim card may not be provsioned for data services..." etc. I popped out his sim and put in mine which is a full plan with data on my captivate and it still gives the same error. it is running 1.5 (cupcake?) unmodified and i just wanted to get some free games for him from the market since you are supposed to be able to connect over wifi without a data package.. or at least thats what we were told.

any ideas?

thanks

hi all,
does anyone here have the problem with the driver?
i installed the driver for this lg gw620, but everytime i put the device in fastboot, win xp always ask android 1.0 driver.

edit:
i have figured it out after spending hours browsing the internet.
finally, the driver is installed properly.
and now i can update lg gw620 to cyanogen froyo.
thanks to xda dev.

    And since we're giving away secrets, here is a handy tool to extract those system.mbn files LG ships. This allows you to extract and browse the filesystem easily without having to flash your phone. It's based on unyaffs because that's basically what the filesystem is, but the LG ones don't use OOB data for the fs, but do have some extra data in them (probably checksums) which needs to be skipped.

    Edit: updated unyaffsmbn to preserve uid & guid (if run as root) and timestamps

    I also have V10T - not sure if it's stable or not tho... It's been a looong time since I looked at a 620. http://www.zacpod.com/files/V10T.zip

    Have you checked out OpenEtna? They had some Cyanogen ports that were actually pretty decent.

    Decompressing the KDZ

    Okay, it took me a while to find the right version of the LG-Utils program to decompress the KDZ file. From those of you following along at home, you want at least version 0.4.2 (the most common version is 0.4.0, which is great if you want to flash your phone with the firmware it appears).

    Okay, for those looking at this thread for the first time, here are a quick set of instructions to get you caught up to ZacPod (as of the 19th anyway).

    (1) Download the firmware: http://csmg.lgmobile.com:9002/swdata/WEBSW/GW620R/ARGSBK/V10c_00/V10C_00.kdz
    (2) Download LG-Utils 0.4.2: http://www.assembla.com/spaces/ks36...eJe5afGb/download?filename=LG-Utils-0.4.2.zip
    (3) Run KP500-Utils-EN.exe (or whatever language you prefer out of the available choices) and select I to extract the KDZ.
    (4) Open the resulting CAB file and extract the DZ file.
    (5) Download DZExtract: http://www.frenchcoder.com/upload/DZExtract-V0.2.zip
    (5) Use DZExtract to extract the MBN files:
    Code: 
    DZExtract -x GW620RAT-V10c-OCT-21-2009-RGS-CA_DZ+0.dz C:\extractedTo\

    Voila, lots of MBN files: amss.mbn (8717kb), partition.mbn (0kb), qcsblhd_cfgdata.mbn (0kb), qcsbl.mbn (32kb), oemsblhd.mbn (0kb), oemsbl.mbn (150kb), amsshd.mbn (0kb), appsboothd.mbn (0kb), appsboot.mbn (215kb), zImage_Ramdisk.mbn (2030kb), System.mbn_0 (95089kb), System.mbn_1 (12158kb)

    Now, the zImage_Ramdisk likely contains the kernel. The question is if there is anything else in there. In a hex editor, it starts with the string "ANDROID!" and later on has "mem=88M console=ttyMSM0 androidboot.console=ttyMSM0". Running strings on the mbn files might yield interesting tidbits.

    System appears to be too big and was broken into two pieces ... I suspect it needs to be put together again before it will be of any use.

    amss.mbn is intriguing ... it starts with the string ELF, which is common of linux executables. Not sure what the smss.mbn is. There are also page after page of "empty" sections (all null's). Are there multiple files in here? I don't think this is a filesystem ...

    partition.mbn is kind of interesting too. It contains the strings MIBIB, WALLPAPER, OEMSBL2, DLOAD, AMSS, APPSBL, FOTAUSD, FOTAPKG, ZIMAGE, SYSTEM, DRM, CACHE, and USERDATA. I'm assuming it defines the partition tables.

    The question really is, what are these mbn files? They don't look like filesystems, but I'm not really familiar with YAFFS2.

    This thread here:
    http://forum.xda-developers.com/showthread.php?t=399249
    Talks a lot about the DZ file format and there is some discussion about MBN files.

    However, it doesn't appear they are in any special format so I tracked down the YAFFS specs (http://www.yaffs.net/yaffs-spec). I'm hoping they might shed some light on what these files really are. Some notes on YAFFS2 are here: http://www.yaffs.net/yaffs-2-specification-and-development-notes, but they are rather out of date.

    Since this thread got revived I may add my 2 cents to the discussion!

    First of all, it seems that the homepage of http://openetna.com/ went down (also the forum and wiki) - i will try to contact cwhchew to find out what happend...

    Secondly, there has been some development for the LG GW620, so this i want to sum up here:

    OpenEtna - the last version based on Android 2.2.1 available on http://code.google.com/p/openetna/ is Openetna V6.3-rc7

    But there has been also some development on Android 2.3.7, there was a project started called openEve.

    OpenEve - There is a port of CyanogenMod 7.2.0-RC0 on the page http://code.google.com/p/openeve/ - also there is a alpha port of Android 4.0.3 available there (CM9 ICS 4.0.3) dated on 2012-01-13

    And finaly there is a project called openEve-continues which is based on the released CyanogenMod 7.2.0 available here: http://code.google.com/p/open-eve-continues/ - it is dated on 2012-07-27

    I hope this helps someone to find the right custom firmware for the good old GW620!

    I also started a entry for the LG GW620 on the XDA wiki: http://forum.xda-developers.com/wiki/LG_GW620
