Samsung Galaxy Tab 7″ (P1000*) – Android ICS CM9 MTD

Greetings Androidians! Clique Aqui para Português.
This is a download page to help CM9 enthusiasts, specially P1000N and P1000L that always get their kernels later than the regular P1000. These are my own builds, from the original sgt7 repo, no modifications.


New opensource partitioning type. Same partitions, just diferent type.
Easy to flash to, but you will have to full flash and repartition to go back do BML, the Saumsung proprietary partitioning, used in all other non-MTD ROMs.

CM9 UNOFFICIAL – sgt7 mtd repo, not official Cyanogenmod nightly.
The sgt7 repo is the original Te4m repo in the development thread, before the merge with CyanogenMod. It will be synced with CM, but will keep extra tweaks, such as the Trebuchet tweaks by sbradymobile and a better recovery.

(OBS: New CM9 builds already contain PDroid patches and @sbradymobile tweaks)

Modem CwM flash updates for MTD ROMs, by cdesai.

PDroid Privacy Protection CwM Patch 20120812.

  • PDroid Patch Install, md5sum: dc9d45d793a7163742c6acdddf68324b
  • PDroid Patch Remove – re-flash your ROM, or copy the original 3 files.

NoMoarPowah! Galaxy Tab stockblue theme based on ironheart’s theme.



  • Use boot.img inside the ROM ZIPs if you want to try other CM9 MTD builds, like the CyanogenMod official and AOKP, which often don’t provide latin (P1000N/L) kernels.
  • Flash with heimdall like this:
    heimdall flash –kernel boot.img –recovery boot.img
  • Or just replace boot.img inside the ROM ZIP with your desired kernel.


ATENTION: I assume you are following the CM9 conversations in the XDA threads. Make sure you have the required flashing background. In sum, if not already in CM9:

  • Must be on Gingerbread.
  • Must be on ext4.
  • Must have CwM Recovery.

The Overcome guide is a good start before you get to CM9.

Easy restock from Gingerbread, in case you get any strange simptoms.

  • Flash full stock Gingerbread (with repartition).
  • Flash Kernel with CwM. Doesn’t have to be Overcome, could be any CF-root kernel for your model. You can use the same one in the CM9 ZIP that you will flash.
  • Boot directly into CwM Recovery, holding VolUp. No need to convert to ext4, since MTD will converto to yaffs2 anyways.
  • Flash CM9 ROM and GApps!


  • Coming from some variations of CM9 you might get assert error status 7. If you are up to editing the update script, try reading this post from HumberOS.
    Or try this in recovery, thanks ayysir.
    Else, do the full restock, Overcome dance.
  • Mobile, Data, 3G problems? This ROM comes with the JPZ modem. You might need to flash your customary modem back. Just copy your modem.bin to /radio in the Tab.
  • Laggy? Slow? Wipe Cache and Dalvik cache. Also try using the following configs in Performance Settings: Processor: Max CPU 1200MHz, Governor ONDEMANDX (go ahead and try others like SmartassV2, Smoothass and Lagfree). Memory Management: zRam 18%, Allow purgin assets and Kernel samepage merging (KSM). And reboot.
  • @sbradymobile – For anybody with a SystemUI FC on the newest build go into Settings > System > Combined bar expanded settings > Expanded settings entries and uncheck/recheck at least one of the settings (I will push the fix this morning).  You can now change the order as well.
  • Wifi sleeping: if your wifi is sleeping when it’s not supposed to, try setting Minimum CPU Speed to 200MHz.

Don’t forget to hit the  button on the XDA posts that you find helpful.

Cheers from Brasil!

    Olá, tudo bem? Estou usando sua CM9 MTD 20120504 – Full ROM, meu tab desliga quando tiro uma foto com ele com a câmera traseira, tem idéia do que pode estar acontecendo? Obrigado!

    Alroger Filho Says:

    Nunca vi desligar.. mas 2 ideais:
    -remova todos UnderVolting (UV) / e ou OverClocking (OC) para testar sem nada.
    -limpa o cache e dados do aplicativo da camera.

    Em ultimo caso um factory wipe pode ajudar tambem.

    Alroger, instalei o nightly 20120508 (get.cm/?device=p1 que por sinal amanheceu hoje fora do ar, ia baixar o 20120509) sobre o do dia 20120507 e meu GT-1000 ficou muito lento. A sua versão 20120508 é diferente? Fiquei com vontade de testar sua versão por conta de customizações que parecem estar incluídas na ROM.

  10. 10
    Alroger Filho Says:

    20120508 fine for me… very smooth.. I added a couple performance tips in the Troubleshoot section above. If it’s laggy, you need to wipe somehing!

    Hi, I tested wi-fi direct yesterday and it doesnt work right until now. Pairing is no problem, but filesharing seems unpossible yet. (Tested with a galaxy S2 as partnerdevice. There you could choose file sharing via wifi direct, but nothing happened. On the SGT i also couldnt choose this opinion.)

    Hi Alroger why you didn’t host 20120510 update here I always use your builds I think yours is better.

  17. 17
    Alroger Filho Says:

    I was about to upload them when the power went down all around my region. I will post them in a few hours.
    Humberos’ build should be just about the same.

  18. 18
    Magdy Says:

    no I tried it before, my HD videos was blinking while playing but your build in the same date was better.

    I think it was 20120505.

    Alroger Filho Says:

    Ok, power back up… ETA 2h.

    Remember that humberos had his build out very early today… so mine might have more fixes. Specially latelly when things are moving fast.

    which modem file for P1000T and what PDroid Patch Install is?

    Daniel Weck Says:

    May 10th build makes my GT-P1000 hot, battery goes down quick, and device goes dead after sleep (black screen)…reboot by long-pressing the power button is required.
    I was using 1.2GHz CPU max, OnDemandX governor, but this was configured via SetCPU.
    I have now disabled SetCPU and I will try with the built-in settings panel. I have also unticked “Force GPU rendering” in the “Development” section. Let’s see if this fixes the problem.
    Regards, Dan

    Could not install 20120516 due to assert problem. I think I will wait for a new version instead. Dont feel confortable with the Humberos instructions on this.

    16-05 release has the same error with get.prop assert.
    Will try to remove the lines with notepad++ to see if it solves…

  45. 45
    Leandro Romao Says:

    Okay! It solved the problem!

    Here’s how:

    1 – Download notepad++ (google it!)
    2 – open the update-cm-9.0.0-RC0-p1l-UNOFFICIAL-20120516-signed.zip (or whatever your release is) with winrar, navigate to META-INF/com/google/android and extract the “updater-script”
    3 – open it with notepad++ and delete the 2 first lines of the file! (don’t leave any space of the lines you deleted!)
    4 – delete the original “updater-script” from inside the zip and drag and drop the one you edited to the same folder insite the zip.

    Good luck!

  46. 46
    Rose Cruz Says:

    Leandro Romao
