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!

    thanks before

  3. 3
    Alroger Filho Says:

    yes, Overcome applies to P1000N also. pay attention to the procedures. what’s important is the procudure to unlock your bootloaders and there is a specific download for P1000N for that. read carefully.

    underTheHood Says:

    I can’t figure out where is the part for how to unlock the bootloader, can you specify it for me? the link maybe? thanks in advice..,

    Alroger Filho Says:

    Well, it’s all in the Overcome Guide. You better read carefully so you don’t miss anything.
    It says “Preppin’ The System…” and the in big RED LETTERs:

    Then you have the instructions on how to root and how to unlock your bootloaders. The bootloaders take you to a link with 2 downloads. 1 for regular P1000 Tablets and the other for P1000 N and L, AKA Latin Tabs.

    Pessoal, nessa vida de navegação, achei um vídeo do Baixaki falando do nosso querido CM9, e até que eles elogiaram a rom. Agora pergunto a vocês, o 3G realmente não funciona ou está errado o vídeo?
    O meu aqui nunca conectou em 3G, e olha que sou do Rio de Janeiro e a cobertura é boa. meu P1000l só fica com sinal de “H” na conexão. abraço a todos.

    after flashing by CM9 20120707 Tab P1000 doesn’t recognize it’s serial number. Why?

  12. 13
    Alroger Filho Says:

    Claro que o 3G funciona! Dicas de modems no artigo. No Brasil usamos outros modems. Anote o que vc usa atualmente antes de tentar o CM9.

  13. 14
    Alroger Filho Says:

    Why? Cause you got some problem. If you dont find the problem then restock and try from scratch!

    Eu estava usando muito bem a rom 20120707 e resolvi subir pra CM9 oficial 20120719.
    O touch parou de funcionar. Além de não poder desbloquear a tela ou inserir o PIN, assim que a tela desligava, sumia para todo o sempre.

    Somente ressucitava entrando em recovery e dando wipe em tudo. Mesmo assim, o problema persistia. Tenho um P1000L.
    Fiz restock p/ 2.3.3 e estou pensando em voltar definitivo p/ HumberOS, pois não tenho tido muitas alegrias (diversos bugs, travamentos e flashs mal sucedidos, mesmo seguindo todas as dicas, além de a bateria durar de um dia p/ o outro sendo que somente utilizo o tab à noite) com o CM9 e a TV faz o tablet antigo um pouco mais atraente em relação aos demais…

    Abraços e sucesso com o desenvolvimento!

  15. 16
    Alroger Filho Says:

    Falta de touch significa kernel errado. Isso acontece qdo faz um flash do P1000 no P1000L ou P1000N. Verifique o nome de arquivo que vc usou… deve ser p1, ao invez de ser p1l.

    De qualquer forma nao existe nenhum novidade apos minha ultima build 20120707, nem no oficial nem no do nosso Te4m sgt7 (para Galaxy Tabs quero dizer). E o CM9 oficial nao tem tudo que o nosso tem.

    O kernel do Humberto ainda tem suas instabilidades.. estou usando o do cdesai ultimamente, que esta dentro do nosso build 20120707.

    hi Alroger,

    there is still a higher priority bug in a lot of the last roms.

    by flashing the newest ICS roms the MAC adress changes to a new one. also trying to change it back manually does not work.
    we tried to change to old MAC address by editing the file “/data/.nvram_net.txt” (WLAN switched off, with root access). Saving was successful, the changed value was available after reopening it.

    but unfortunately: after restarting the tablet the change is lost and the tablet sets the other MAC adress again. also in nvram_net.txt it changes back.
    do you have any idea how to restore the old MAC address? thanks in advance!

  17. 18
    Alroger Filho Says:

    No such problem anymore. You must restock, check that you have your correct IMEI, modem and MAC and flash the latest CM9.

    If you tried several builds since the ICS/CM9 builds started testing you might have gotten that problem, and you need to the restock from scracth.

    Latest CM9 does not alter IMEI, MAC, S/N or anything.

    Alroger Filho Says:


    at least the Te4m sgt7 builds! I don’t usually try the Official nightly builds.
