    Hi…i have samsung tab GT-P1000 with android froyo 2.2 and i want to update to android jelly bean 4.2.2. I have copied the 2 files to external sd-card. My problem is when i am in recovery mode…i do not see ‘install ZIP from sd-card but instead i see ‘apply’ only. So my progress is just until there. Its just the same if i go through the recovery mode from ROM Manager Apps , where i can choose the 2 files succesfully but it will still go to recovery mode like i mentioned before. Any advise? Thank you.

    I have upgraded my Galaxy Tab P1000 smoothly. Now I’m enjoying using it.
    Then I help my friend to follow suit. However, this time was not so lucky for me. Successfully installed cm-10.1-20130504-EXPERIMENTAL-p1-cdesai zip file. But not so for gapps-jb-20130301-signed. Then I switched off and on then tried to recover to the old version since I did my back up. However after recover and reboot it hanged. Power up again (using power & Volume +) I got message could not locate path E. How do I go about it? Appreciate your advice.

    Thank you

    Has anyone got this upgrade to work (from 2.3.3 Gingerbread) to Jellybean 4.2.2
    Help needed I need a Guide on how to do a full back up of GT-P1000 . Kies does not do it.

    Link to Google Apps Package takes me to Cyanogen Developer page. Which package should be downloaded. Author says Download to Computer then Load via usb onto Tab. Where (destination) should it be loaded.

    Observing the comments, it seems that the Author has a good offering to make But for us mere mortals, we need more detail on procedure !! Bushbug

  • hassan


  • Russ

    Installed, seemed to work fine, but my computer no longer recognises device when I plug into USB. Also won’t pick up 5GHZ wifi. WhatsApp doesn’t run

  • Brian P Lavelle

    It seems that there are a lot of difficulties in trying to execute what the “Experts” advise for rooting etc.
    Does Any Expert ever reply to Queries ??
    How to do a Full Backup inc. Micro SD is not covered in Guide. Kies is not reliable and freezes.
    How to differentiate between Tab models.

    Mine is Samsung Galaxy Tab 7″ GT-P1000 wiFi +GSM E,H,& 3G +GPS inc. phone.

    Cymogen says software not suitable for this model !!

    Publishing half the exercise is a danger to your followers and grossly irresponsible, sticking a disclaimer at the end is neat.

  • Bosun

    Thanks for your write up. I followed your procedure and my device is now functional. However, there are some issues that came up. The device does not mount my external sd card anymore. The second is that I cannot use the telephone anymore because it does not recognize any mobile network. Is there anything to be done to correct this or is this a penalty for installing this android os?

  • Sam

    after doing all the above process booting took 10 minutes time. but after that it said “unfortunately setup wizard not working” this is the error message i got. so i restored my old backup. please help me out to solve this issue.

    I don’t see the option install zip from sd card while the sd card is in the p1000 and the files are in the root of the sd card…?

    • Pradeep Neela

      no, it wont work on P1000

  • Dave

    Sorry. I did this process exactly to a “T”, but, alas, in the end it would not install because it came back to me with a message that the file is not signed or some such nonsense. And……all of that after wiping….Bummer.
