    i wanted to try out if the path of the files are all correct.. without formatting or partitioning the sd card..

    so..
    installed java jdk..
    installed androidsdk..
    have problems with fetching... even after selecting fetch http:// box...
    i still continued..
    (my phone is already rooted... usb debugging enabled.. portals n tools selected)

    open commandprompt..
    adb devices..
    device found..

    adb shell
    $...
    su... ok for request...
    #cd/sdcard/apps2sd

    not found!

    why is that so...?
    i extracted the files to the phone in memory card access mode to a folder named apps2sd...

    is that right?
    im not really sure what is meant by "extract the files to the root of your phone"
    sdcard/apps2sd...


    help please...

    /* tried unmounting... no change... added the command in build.prop.. no change...

    uk based motorola xt720...


    fixed..
    din notice the space in cd(space)/sdcard....

    however.......


    the apps2sd did not install...
    while running the command for apps2sd..
    it said file already existed... ext2.ko...
    this is becasue of the previous apps2card app i guess...
    but i tried running command promt right after reeboot... still no good..
    how to delete the old file???????????????????????????????????????????

    the jit was installed properly...

    phone still crashes after turning on the camera at times... like twice a day...!!

    (((((((

    did i mention the phone now on crack!!
    haha..
    so fast!!!!!

    benchmark 702...


    thank you.....

    happy new year to all ))))))))))

    Hello everyone ! Sorry but i am in need of some help. I am new to this and like others found out after buying the phone that moto wont update xt720 to froyo got me a little upset. I never rooted or done anything with phones before so please i ask for someone to help me
    I already formatted my sd card well hope the right way with gparted.
    i have 8gig card so i did
    fat 32 about 5gig and ext3 2.5gig and some was left but instruction dont say what to do with that so i left it unallocated something like that.
    also i had a hard time figuring out how to flag fat 32 as boot because it says to apply changes at end and i had to apply changes then right click flag management and then select boot.
    Step Two: Copy files to the microSD card
    those this mean both files
    DOWNLOAD UNMODIFIED FIRMWARES HERE
    Central Europe STR_U2_01.1E.0

    i only did the STR and load it to the card once it was unrar. I opened in the phone with the es manager and did the universalandroot then ask me to root phone which i did and now is rooted.

    Please i need lots of help with
    Step Five: Run the script
    i open the command and do what it says but is not found i cant pass that step at all. All my drivers are installed.
    a video will be so helpful or screen shoots or if anyone is willing to call me ok too.

    please HELP !

    That error of "Error loading ext2.ko, exiting script ..." means the ext2.ko modules was not able to load into the kernel. This normally means the microSD card is not partitioned correctly.


    • Make sure that the first partition is fat32 and flagged as boot (and primary)
    • Make sure that the second partition is ext3 (and primary)

    Edit: I just uploaded a bug-fixed copy of the xt720-optimizer.rar. The only changes made were to force the overwrite of ext2.ko if it already exists and remove the line which gives "bad mode" on theme install. These were just minor annoyances.

    i am a complete noob to the android world, and i apologize if this is overtly ignorant on my part but ive done everything as in the guide to get 2.2 on the milestone and i am still having problem. ive had to factory reset the phone twice now and it still wont go through. i have partitioned the sd card with GPL fat32 14xxx mb and ext3 1xxx mb, both primary with fat32 as boot, the only other thing is a 4mb unallocated portion in the begining of it all which i always thought normal. i have gained adb access just fine. when i enter the sh install.sh into the command prompt it brings up the 1-9 menu. 1 installs fine, 2 apps2sd never works and gets the exact error mentioned above with the "Error loading ext2.ko, exiting script ...", so i skip to 3-8 just fine. then i run 9 the cleanup and reboot. it reboots and milestone overclock is there, but thats it. no apps2sd which is understandable because it errored, but the new themes and 2.2 arent loading either. is it all hinged on apps2sd and if so, how can i get that to work? i appreciate any help, thanks.

    ok i reflashed the phone and sd card, and got everything to install correctly, so the error loading apps2sd corrected itself, i found a post here that directed to do to that and it works, thanks.

    but now once it rebooted, nothing looks different, and i cant find the app2sd application. am i missing something? it seems everything else worked, i have overclock and all the installs from the adb access prompt worked. do i need to somehow tell the phone to use the new 2.2 JIT?

    I have been looking at install.sh to find out what could have been the difference that causes different failures if not used with one of the tested ROM above. The first thing I noticed is (European U2_01.1E.0) install.sh tries to remount mtdblock6 on /system as read-write:

    Code:
     mount -t yaffs2 -o rw,remount /dev/block/mtdblock6 /system
    But in my phone (India ROM, STR_U2_01.1E.0) I see the partition is a little different, /system is mounted off /dev/block/mtbblock7

    Code:
    $ /system/bin/busybox df -h
    /system/bin/busybox df -h
    Filesystem                Size      Used Available Use% Mounted on
    tmpfs                   112.4M         0    112.4M   0% /dev
    tmpfs                     4.0M         0      4.0M   0% /sqlite_stmt_journals
    /dev/block/mtdblock7    199.6M    172.2M     27.4M  86% /system
    /dev/block/mtdblock9    173.1M    155.5M     17.6M  90% /data
    /dev/block/mtdblock8    106.0M     17.6M     88.4M  17% /cache
    /dev/block/mtdblock6      8.8M      8.5M    300.0K  97% /cdrom
    tmpfs                     2.0M     28.0K      2.0M   1% /tmp
    tmpfs                     2.0M         0      2.0M   0% /skttmp
    /dev/block/mtdblock0      1.5M      1.2M    268.0K  83% /pds
    The copying stuff would have failed otherwise.

    Trying to investigate why most people's phone gets stuck at reboot after app2sd install. But generally they get thru if they flash one of the stock ROM first (and use corresponding script). So most likely it is not a SD card partitioning problem. We expect the first partition to be FAT32 which will show up as /dev/block/mmcblk0p1, and second to be ext2 which will be /dev/block/mmcblk0p2 (the same assumption is done in install.sh). Afterwards it just moves /data/app to /system/sd (where it was mounted) and make a symlink. Even so far so good. During boot the script is modified to mount /system/sd. So not much ROM dependent functionality we are doing here. So this also looks nice, my only concern is, it is done assuming original boot script will be done by then. I don't know if there is a chance that original mot_boot_mode tries to access /data/app and crashes due to unavailability of the same.

    Sorry for back to back posts.

    I only cherry-picked JIT stuffs from the optimizer. To do so, here is the change I made to install.sh for my India ROM, I also made the backup more robust in case we want to go back:
