  18. 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

  19. Upgrade went good, everething is working fine.
    One problem i noticed, not possible anymore to connect to PC to put something on it.

    someone got an idee?

  20. Best

  22. Hi guys, I have a galaxy tab gt-p1000
    I have installed the cwm based recovery v5.0.2.8. and I’d like to install Jellybean 4.2.2
    I have followed the guide but when I install the firmware I get the error message “assert failed status 7 many thanks

  23. Nice tutorial. It works fine on my p1000… thanks

  24. 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

  25. 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

  26. 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.

  27. 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?

  28. 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.

  29. Thanks great

  30. It is showing the below error
    E: failed to verify whole-file signature
    E: signature verification failed
    Installation aborted

  35. im doing exactly what you wrote above but it keeps saying that it did not find the file

  36. cannot upgrade galaxy tab version

  37. After installing this onto my galaxy tab it now randomly shuts down and when I attempt to power it back up it takes a few presses of the power button before it actually shows sings of life?

  38. May I use this Firmware with Galaxy Tab GT-P1010? Thanks a lot for your responses…

  39. Hi,
    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…?

  40. Will this update work on the GT-P1010?

  41. 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.

  42. hello,

    Is it stable ? Is everything working ? (Phone call, data, 3G, HSPA and wifi hotspot) ?

  43. very valuable feed.thank u.
