    Hi, I've tried to install the new CyanogenMod, but while I launch the .zip install, it returns "assert failed: getprop("ro.product.device") == "E15i" || [...]".

    Rebooting the phone, from terminal I have looked for getprop and values are ok.

    I have try to install both before and after system format, but the error persist.

    Anyone can help me ?

    sorry not enough info to help, so i am guessing...

    are you using xRecovery to install?
    you should be using clockworkmod recovery to install

    cheers :)

    come....anyone, plz help me...or did i need to flash it using flashtool??

    Apologies... This ROM is a bit fussy (signed ROM).

    It requires Xperia X8 E15i NOT E15a
    And baseband 015 = X8 Shakira E15i_2.0.2.A.0.24_ril.ftf

    The reason for your error message is either...
    Wrong Xperia X8 Model or wrong baseband.

    cheers :)

    mine is E15i......baseband also 015 n the file i download is shakira...so whts the problem?? file.ftf? is that means i need to flash it using flashtool???

    root = done

    I'm gonna tell anybody who reads this exactly what i've done, and why it is still not working:
    a) Rooted my phone.
    b) Got all thingys (xrecovery blah blah blah...) installed.
    c) Cyanogenmod 6 (android 2.2) previously installed.
    d) Got baseband ... 015.
    e) My phone model is E15i.

    What I did was:
    a) download CM7.1 from the website.
    b) Copied update-cm-7.1.0-x8-signed.zip to my sdcard.
    c) rebooted to clockwork mod.
    d) tried to install zip from sdcard.
    if anybody can tell me where i went wrong, i'd be really grateful for it.
    Thanks in advance.

    Ok same problem as everyone else asset failed error my phone is E15i and 15 baseband. Everything done exactly but still the error. Maybe the zip is corrupted?

    umm, i can see a few reasons why maybe you're wrong:

    a) i've downloaded the file from different websites, which means there isn't any problem with cyanogen's servers (and the files stored in it).
    b) cyanogen would never release an update which doesn't work.

    at the same time, i really really hope you're right, since i heard cm7.1 is awesome, and i'd really love to have it on my x8.

    unfortunately, we x8 users have extremely limited options.
    CM is the best custom ROM for any phone, since it is extensively tested by loads of people and the developers are pretty good, too.
    Other ROMs like the ones you mentioned are developed by a few kind people who have the time and resources to develop ROMs for a particular phone.
    These unfortunately cannot match up to CM in terms of stability and performance, since there are always sure to be a few bugs around, and the comparatively less number of users means there aren't as many people to identify such things.

    So, maybe what I'm saying is, we're all in the same boat, stuck on an old OS, waiting for someone to identify the problem with CM7.1 for x8, so that we may use it too.
