Samsung Galaxy Tab P1000 with Android 4.3 – CyanogenMod 10.2

CyanogenMod 10.1 - Android 4.2.1 - Samsung Galaxy Tab 7 CyanogenMod 10.1 - Android 4.2.1 - Samsung Galaxy Tab 7 CyanogenMod 10.1 - Android 4.2.1 - Samsung Galaxy Tab 7

One more time I wanted to give another breath to my Samsung Galaxy Tab 7, because prices here in Venezuela are not encouraging, so I decided to install Cyanogenmod 10.2 con Android 4.3, thanks to HumberOS. This upgrade is valid only for the Latin American model, I mean Samsung Galaxy Tab 7 P1000N (o P1000L). Here I leave all you need to do so, and some tips.

Considerations

  • Remember that only you are responsible of what you do to your tablet. Although I followed this method, I won’t take any responsibility if you brick your tablet.
  • Backup your current rom and any data. This will help you to go back if something goes wrong.
  • Do this procedure with at least 75% of battery charge.
  • This rom ONLY works on P1000N / P1000L.

Requisites

  • To have installed a Recovery  capable of loading updates ( like CWM Recovery)

Installing

  1. Download and copy into internal o external sdcard’s root directory files cm-10.2-20130921-HumberOS-p1.zip, and gapps-jb-20130813-signed.zip. The first one is the ROM and the second one are the Googles’ apps for this Android version.
  2. Turn off the tablet and then turn it on in the CWM Recovery by pressing Power On + Volume Up buttons at the same time. When it boots you should see a screen like this one:

     CyanogenMod 10.1 - Android 4.2.1 - Samsung Galaxy Tab 7

  3. Make wipe data / factory reset and wipe dalvik cache on the wipe menu.
  4. On the  Install menu go to choose zip from internal sdcard (or choose zip from external sdcard if it’s your case). Choose  the cm-10.2-20130921-HumberOS-p1.zip file to flash it to the tablet.
  5. Later you must install the Google’s apps. To do so you have to go one more time to choose zip from internal sdcard option and choose the file gapps-jb-20130813-signed.zip.
  6. Once installed, go to reboot menu and reboot the tablet by choosing reboot system. The tablet will boot with the CyanogenMod’s logo. It will last quite a few, don’t turn off the tablet. Be patient.
  7. When it had finished, follow the tablet’s settings wizard, and enjoy it!

IMEI no valid

If you reboot your tablet and got the Invalid IMEI error as show below, I recommend you to got to the Stock ROM 2.3.3, and the update with the HumberOS’s kernel qith grants you root permission,  and finally do the above steps for upgrading to 4.3:

IMEI issue

The process can be a little tedious but it must be done to use a fresh operating system so it can recognize the device’s IMEI.

I have a Samsung Galaxy Tab 7 first edition, and due to Samsung no longer released updates for this device I couldn’t try Android 4.x.x. But I freind reminded me: go to the community and install a rom like CyanogenMod. In fact he gave me a link to the image that supposedly works for my tablet, but I couldn’t upgrade because it said it wasn’t compatible. Then I remembered HumberOS was basing its ROM on CyanogenMod so I decided to try it’s 10.1 version, so I put here all you need to install it on your SamsungGalaxy Tab P1000 (N o L).

Considerations

  • Remember that only you are responsible of what you do to your tablet. Although I followed this method, I won’t take any responsibility if you brick your tablet.
  • Backup your current rom and any data. This will help you to go back if something goes wrong.

  4. On the  Install menu go to choose zip from internal sdcard (or choose zip from external sdcard if it’s your case). Choose  the HumberOS-2.1.zip file to flash it to the tablet.
  5. Later you must install the Google’s apps. To do so you have to go one more time to choose zip from internal sdcard option and choose the file gapps-jb-20130301-signed.zip.
  6. Once installed, go to reboot menu and reboot the tablet by choosing reboot system. The tablet will boot with the CyanogenMod’s logo. It will last quite a few, don’t turn off the tablet. Be patient.
  7. When it had finished, follow the tablet’s settings wizard, and enjoy it!

IMEI no valid

Every time you reboot the tablet you’ll get a message saying your IMEI is not valid, bu all phone and tablet functions works correctly, even the 3G connection:

Stock ROM Gingerbread 2.3.3 for Samsung Galaxy Tab 7 (P1000N)

If you want to upgrade your Galaxy Tab 7 version P1000N to Gingerbread 2.3.3, here I left the needed  steps. This is the stock rom, I mean, it’s not rooted, all work and it includes the new market and all Samsung’s apps (like  (Swype, Music, standar browser,  etc). Useful if you need to be on this rom as a requisite to install another one,  or  just for having a stock rom to apply the warrant.

Considerations

  • Remember that only you are responsible of what you do to your tablet. Although I followed this method, I won’t take responsibility if you brick your tablet.
  • Backup your current rom and any data. This will help you to go back if something goes wrong.
  • Do this procedure with at least 75% of battery charge.
  • This rom ONLY works on P1000N.  For other stock roms  (P1000L, Verizon, CDMA, etc) you better check the xda-developer’s forum.

Requisites

  • The procedure use Heimdall. To be more precise I used the command line version for Linux on Debian, although there is a GUI version for Linux and other operating systems such as Windows and Mac.

Installing

  1. Download and extract Stock ROM  Gingerbread 2.3.3 P1000N file.
  2. Turn off the tablet and boot it up in the Download mode by pressing the power and volume down buttons  (Power On + Volume Down). After booting the tablet will show a image like this one:
  3. Connect the tablet to the PC running Linux, in a terminal as root go to the extracted directory Stock Gingerbread 2.3.3 , and type:
    heimdall flash --repartition --pit gt-p1000_mr.pit --IBL+PBL boot.bin --SBL2 Sbl.bin --KERNEL zImage --FACTORYFS factoryfs.rfs --CACHE cache.rfs --DBDATAFS dbdata.rfs --MODEM modem.bin

    Warning: Double check the options passed to Heimdall because your can brick your tablet. For instance check all files are present in the directory.

  4. The tablet will reboot by itself. Wait until the system boots (it will last a little bit, but don’t turn off the tablet until it finishes to boot).
  5. Follow the tablet’s configuration wizard, and enjoy!

CyanogenMod 7 (Gingerbread) for Samsung Galaxy Tab 7

The Galaxy Tab 7 stock rom has interesting features like Swype, a flash compatible browser, Samsung apps like Kobo, among other things,but you can be interested in trying out another rom to get a better performance from your device. So, I decided to try out CyanogenMod 7 (Gingerbread 2.3.7) , because it can add the tablet to my VPN (I tried the OpenVPN option but it just doesn’t connect to the server). Without further ado, let’s see how to install this rom on the tablet.

Before beginning

  • Backup your current rom and any data. This will help you to go back if something goes wrong.
  • Do this procedure with at least 75% of battery charge.
  • Remember that only you are responsible of what you do to your tablet. Although I followed this method, I won’t take responsibility if you brick your tablet.

Considerations

  • This rom works on GSM tabs  (Euro, US ATT/TMO), with JQ1 (Gingerbread) unprotected bootloaders that can run Euro JQ1 ROM and gt-p1000_mr.pit partitioning. This rom doesn’t support CDMA tabs.  LTN tans are supported using included experimental kernel (this is my case).
  • In general all work, except movie capture (taking photos does work) ans some issue with the Market, which its solution is explained later.

Requisites

  • It’s recommended to have official Gingerbread 2.3.3 on the tablet
  • The procedure use Heimdall. To be more precise I used the command line version for Linux on Debian testing, although there is a GUI version for Linux and other operating systems such like Windows and Mac.

Installing

  1. Download and extract ROM Cyanogenmod 7 Galaxy Tab file.
  2. Turn off the tablet and boot it up in the Download mode by pressing the power and volume down buttons  (Power On + Volume Down). After booting the tablet will show a image like this one:
  3. Connect the tablet to the PC running Linux, in a terminal as root go to the extracted directory CM7 , and type:
    heimdall flash --repartition --pit gt-p1000_mr.pit --primary-boot LTN/boot.bin --secondary-boot LTN/sbl.bin --kernel LTN/zImage --factoryfs factoryfs.ext4 --cache cache.ext4 --dbdata dbdata.ext4 --modem modem.bin

    Warning: Double check the options passed to Heimdall because your can brick your tablet. For instance, check all files exist in the folder.

In my case I used the experimental kernel for LTN tablets, if is not your case thet use the files outside the LTN directory (I mean, remove the “LNT/”, example –kernel zImage instead of –kernel LTN/zImage and so on). Once Heimdall finish to flash the tablet it will boot CyanogenMod 7. Be patient because the first time it lasts a little bit (remember the Dalvik cache will be building at that time).

Android Market issues

The new Market 3.x.y is more strict about the device resolution checking. That means there will be some applications reporting themselves as incompatible with your device and the Market just won’t install them. To fix this there are two solutions:

  • Increase the DPI value to 240 by editing the file /system/build.prop, at about line 37 change to:
    ro.sf.lcd_density=240

    In addition you must delete any update of the Market in Menu > Manage Applications > All > Market

  • Install the old Market 2.x.y using Old Market app,  which allow you to go back to the new Market whenever you want..

Of both option I prefer the second one because changing the DPI modifies the tablet’s display resolution, and even though it doesn’t look bad icons and apps are a little big for my taste. On the other and, every time you change the DPI you must reboot your tablet.

Here I leave some extra snapshot if you want to see how it looks with some customization:
