This thread is reserved for nightly builds of CyanogenMod Rom for Samsung Captivate.

All Samsung Roms run on top of BML/RFS, CyanogenMod 7 does NOT.

It runs on MTD/yaffs2 (like Nexus One) which means you'll not able to flash just any kernel or run just any other filesystem you want. Use it as it is if possible, otherwise confirm with the kernel developer that you are trying to install whether it would work with CM. We do not support other kernels and know nothing about their capabilities or compatibility. Only the data partition, which is on movinand, is ext4 like on speedmod or voodoo ("lagfix"). No "lagfix" is necessary because this does not use any Samsung proprietary file systems.

CyanogenMod is a free, community built distribution of Android 2.3 (Gingerbread) which greatly extends the capabilities of your phone.

** These CyanogenMod builds are highly experimental and unsupported.
** Please refrain from submitting bug reports for any issues
** you may encounter while running one of these builds.
** Submitting bug reports on nightly builds is the leading 
** cause of male impotence.
What are Nightly builds? Auto compiled build of the latest CyanogenMod source from github. This version changes each night and aren't officially supported.
If you find bugs/issues you can/must discuss here (do not submit nightlies bugs on CyanogenMod issue tracker).

Warning : Not for new users, flash this build only if you know what you are doing !!! Make SURE you can get into Download mode using only buttons (no other method, Download mode from just buttons is essential).


Latest version:
Check the md5sum if you want to be sure that the download worked (different OSes have different programs that do md5, on ubuntu it is md5sum that you run against the zip you download and compare to the md5sum number shown on the download website). ROMManager does this automatically for ROMs you download via ROMManager.

- First time flashing CM 7 to your Captivate (or coming from another ROM)?

Easy way:
  1. Start with a rooted Eclair/Froyo running Eclair/Froyo Bootloaders (do not ask us how to do this).
  2. Install ROMManager Premium.
  3. Flash ClockworkMod Recovery. Pick Captivate (MTD) (ignore the warning about not having an official, pick ClockworkMod 2.x).
  4. Make sure you can reboot into ClockworkMod recovery from ROMManager. Reboot and get back into ROMManager Premium.
  5. Choose download ROMs.
  6. Pick the CyanogenMod Nightlies.
  7. Check the Google Apps addon.
  8. Check Backup current ROM!
  9. Check wipe data, cache, dalvik cache.
  10. Let ROMManager finish the installation.

Harder way:
  1. Make sure you're running a Eclair/Froyo Firmware (2.1 or 2.2) and Eclair/Froyo Bootloaders!
  2. Root your device and install ClockworkMod Recovery.
  3. Do a Nandroid backup!
  4. WIPE (wipe data/factory reset + wipe cache partition)
  5. Install the ROM from internal sdcard using ClockworkMod Recovery
  6. Optionally install the Google Addon (through ROMManager is easiest)

- Upgrading from earlier CM7?

ROM Manager method:
  1. Install ROMManager Premium.
  2. Flash ClockworkMod Recovery. Pick Captivate (MTD) (ignore the warning about not having an official, pick ClockworkMod 3.x).
  3. Choose Download ROMs.
  4. Pick the CyanogenMod Nightlies.
  5. Check the Google Apps addon.
  6. Check Backup current ROM!
  7. Check wipe cache, dalvik cache.
  8. Let ROMManager finish the installation.

Clockwork Mod method:
  1. Download and push the ROM zip file to the sdcard.
  2. Reboot into recovery.
  3. Do a Nandroid Backup!
  4. Install the ROM zip from sdcard (your Google apps will be backed up automatically)

There are no Google Apps bundled with CM ROMs, because Google asked Cyanogen to remove copyrighted apps. After flashing the rom, don't forget to flash Google Addon package if you want it. ROM Manager will allow you to flash it if you just go into it and after flashing the ClockworkMod recovery for MTD devices, choose Download ROMs, and pick Google Apps.

Just want to make sure my understanding is correct

- Don't use "reboot recovery" command or other shiny things to do this!
Flash cm7-captivate-initial-kernel.tar as pda using odin without auto-reboot

So after flash of efs pull battery, get to dl mode, flash initial kernel with auto reboot off. Pull bay after flash go back to recovery?

Do a wipe

Factory restore in clockwork?

Install the Nexus S USB-Drivers from SDK-Manager if you're using windows.

Are these drivers needed to use odin our just files transfers

To revert to a samsung rom, simply use odin with repartition option enabled.

Does odin one click qualify here or use full version?

Just making sure I understand instructions fully, thanks

Thank you very much but because this is a test release, I will keep my eye very close to see how everyone else does on this ROM. Actually, I'm scared to flash this until it's stable enough for a daily driver .
