  1. my problem is the links don’t open, i can’t download the zip files. any other download route?

  2. Hi Neal,
    I just wanted to know why do we first flash with speed mod kernel ?
    Because the Cyanogen Mod 7.1 has its own kernel in the RAR file (it has z-image)
    That all.


  3. When i get into rom manager because i didnt see the cwm app what do i do.

  4. Hi Neal..I followed each n every step in this article, after installing cyan 7.1, in about phone the kernel does not show as the \speedmod\ but the \pawitp\ kernel. is that ok? or did something go wrong? cause i did the speedmod kernel and it did show that it had speedmod kernel before installing cyan. plz reply thanx.

  5. hi neal,

    i successfully installed ICS Cyanogen MOD 9 Android 4.0 Firmware, but i found out that some features is missing and my sd card showing no files. however, would you please provide some instructions how to downgrade my phone to its previous firmware?!

    thank you.

  6. Hi Neal, I have successfully updated but not able to send SMS. When i wanted to update the message centre no, i didn’t find any such option. Could you pls help and guide.


    • you need to update with XXJVT version as its a beta and unstable version!

      • Thanks for the reply Neal but do you mean i can’t be on Cyanogen Custom ROM? I had already updated to XXJVT and post that only i updated to Cyanogen. The only issue is SMS, rest all seems fine. Anyways if that is the only option then can i simply follow the process mentioned in “http://androidadvices.com/samsung-galaxy-gt-i9000-steps-install-gingerbread-235-xxjvt-firmware/”. And also this will ensure my phone not rooted any more as the process mentioned here would unroot the device. BTW could you pls suggest some stable custom ROM’s which would support XXJVT.

        Thanks in advance.

  7. Hi,

    I tried the process but when i click \install zip from SD card\ the screen goes blank… but when i click the home button the screen again comes to the original section with all other options. What shall i do know???


  8. hey neal im on xxjvt rooted can i update to cyanogen mod 7.1 reply a.s.a.p

  9. Hi Neal!

    First of all thank you very much for providing the best solutions to update Android phones with simple procedures. Keep up the good work buddy.

    Please let me know the best ROM from my Samsung Galaxy S GT I9000. The reason why I want to change the software is that there is no option to input the proxy settings in wireless settings advance options even when I updated it to Cynogen 7.1 following your procedure online. Please help.


  10. Hi Neal,

    Your instructions refer to XXJVS, i have XXJVT rooted with clockworkMod, can I proceed without reflashing with XXJVS?

  11. after i press on install zip from sd card it just goes blank and doesnt do any thing what should i do (i tried again and again following the instructions).

  12. just a quick update. flashing cm7.1 on xfjva is not recommended :)

    i’ve re-flashed it on xxjvt and it’s now more stable.

    issues that i faced (at one time or another) with cm7.1:

    1.force close – a lot of times. no specific apps that i know of. solution – re-installing, the affected apps works fine after that but very annoying
    2. freakiest of all was my wifi connection keeps activating by itself even after turning it off. solution – wipe cache and re-flash cm7.1 in recovery mode
    3. titanium backup doesn’t seem to work well with cm7.1

    overall, i’m very pleased with cm7.1 except for the various issues highlighted, which, although annoying, can be resolved with re-installation and re-flashing.

    personally, i find MyBackup works best with CM7.1

  13. Maybe its not compatible with xxjvt!

  14. when i install it on xxjvt, it restarts again and again. i think i brick my phone? is your instructions correct?
