Question on CyanogenMod 7 for AT&T Samsung Galaxy S II

[5942marine]

Quick question here. After I flash my Galaxy SII with the CyanogenMod, if for some reason I want to go back to the previous rom that I backed up, do you always have to do a WIPE (wipe data/factory reset + wipe cache partition) before you flash the new rom?

Apologize for the noob question.

You don't HAVE to, but don't be surprised if you have random fc issues. Just use titanium backup to backup apps and restore.

Quick question: Don't have the necessary amount of post to post this in the following forum: http://forum.xda-developers.com/showthread.php?t=1285823

When I got to apply the zip from the sdcard, I get the following error:

e: failed to verify whole-file signature
E: signature verification failed
Installation aborted.

Yesterday, I flashed the CLOCKWORKMOD-RECOVERY FOR GALAXY S II (AT&T) and rooted it. Then I installed Rom Manager, made a few backups, etc.

When I open Rom Manager, I do see the following:

Current Recovery: ClockworkMod 4.0.1.5

Now, I believe this might be due to installing the ClockWorkMod in the Rom Manager, would this be the issue I'm facing?

I had this issue as well. I reverted back to stock and rooted/flashed CWM from the xda thread instead. ROM Manger version of CWM must be for international only.

So to clarify, I need to flash this back to stock and re-do the process correct?

Did you use the following thread: http://forum.xda-developers.com/showthread.php?t=1286192

Also, theirs a update.zip in the root of the sdcard. When I go to apply it, i get the same error message as above.

E: failed to verify whole-file signature and so on.

Do I need to apply this zip at all?

Okay, was able to install the rom. I was doing it wrong. I needed to power off the device, then press Vol up and power. Some reason, getting into CWR that way seems to work, rather than when you boot into recovery from the Rom Manager app.

Yeah I'm pretty sure at this point ROM Manager is useless for us. I'm definitely going to avoid doing anything through RM until they have it set up for the ATT version.

Dont use RM for CM7 for now.

I'm surprised that worked. It should be VolUp + VolDn + Power.

Don't use ROM Manager. It caused nothing but problems on the Infuse, and is causing nothing but problems here. Use the CWM included in every custom kernel that has been posted here so far.

If install cm7 will it change the file system like it did on the captivate

Just so I'm crystal clear, that means you need to power off your phone and do the Volume UP / Down and Press power to enter CWM correct?

Which brings up another point, according to this: http://forum.xda-developers.com/showthread.php?t=1285823

You have to press Vol Up and Power button. But for my AT&T Galaxy SII, i have to press both Vol Up/Down to get into it.

Sorry, I meant to say both Vol Up and Down + Power.
