I have a couple questions about CWM and backups:
Is there a difference between flashing update.zip and installing a zip from the sdcard in CWM?
Also, let's say I make a change to boot.img and system.img and something goes wrong. Instead of flashing the backups of those two images from my computer to my phone using fastboot, can I just place them both in a zip file and install it from CWM? Would I need to include any other files?
How come a nandroid backup makes a system.ext4.tar and not a system.img? How do I turn that into a system.img?
How come I need unyaffs to read cache, data, and system.img files? I thought the filesystem was ext4 and not YAFFS?
Flashing an update.zip looks for a file on the root of your sd called that and flashes it. Installing a zip let's you choose.
You need to put a few more files into the zip. An update script and binary
Update to romracers recovery and you can do an advanced restore just using certain parts of a nandroid.
That recovery also makes.. Img files rather than tars

So I found some links about the update-script and I'll be reading those shortly, but after skimming them I didn't see any mention of the binary. Is the binary an executable version of the same script or something else? Any links?
So what your saying is I could just skip the update.zip stuff, extract the images from the zip, and use advanced restore to flash each image? Obviously more work but it's good to know if these two processes are equivalent.
Actually, I just made a recovery using romracer's CWM and boot and recovery are .img files while cache, data, and system are ext4.tar files. pds is .ext3.tar and .android_secure is .vfat.tar. So do you really get system files as .img files? And if so, what's wrong with my CWM? If not, the original question holds: why doesn't CWM make an image of each partition, and instead use a tar? For compression? How would I make this a flashable .img file?
And also the last question about ext4 and YAFFS is still there. Thanks.
Most of those I'm really not sure. The update binary is the same for every zip. Just grab it from a rom or theme
I would go with the cwm zips. Way easier once you get them working.

I was just looking at this too. My old recoveries from before atrix4.1 was released were all .img files and the post atrix4.1 backups are .ext3.tar (except for boot.img and recovery.img). I'm on a stock deodexed GB ROM, so I don't have any ext4 partitions. I think he changed this with the newest update so CWM can recognize the ext type and mount them appropriately.
This post should hopefully clarify a bit more than I can. I'm relatively new to all this so I'm still learning different aspects of modding. I'm guessing you have some ext4's because you're running one of the newer custom ROM's?
I noticed every flashable zip has one. If i merge to flashable zips what do I do with the update-binary? Is it important?
Its the program that executes the commands in the update-script, but dont quote me on that

i want to make some changes to the build.prop... it might lead to bootloop....so i want to make a flashable zip backup of original build.prop, so that i can flash it via cwm to revert the changes.... How to make that zip backup file?

How can I make my own .zip files with say the latest twrp 2.8.1.0 that can be flashed in recovery let's say since I can't find most I'd like to be able to jus extract the file if need be and create my own flashable .zip on my i9100m
