Hi,

As the Title says OFFICIAL Cyanagenmod 7.2 is here!!! The aim of this thread is to let you know about how to install, remove, report any bugs and anything else that is relavant.

Before you install its very important that you make note of your current firmware version and baseband should you want to go back. Carrier branded firmwares are harder to find than generic and it will be essential you know what it is exactly (See uninstall section about checkfusdownloader.exe)

Installing:-

1 - You'll need to root your phone. Look HERE

2 - You'll need ClockworkMOD recovery 5 (NOT ROM MANAGER) HERE

3 - Boot into recovery (turn phone on holding home key) and choose .zip from SD card. Select the CWM zip you just downloaded and apply.

4 - Go to Galaxy ace Cyanagenmod 7.2 download and download the file. Place on SD card. IMPORTANT - our device is known as cooper on Cyanagen site, not ACE - that is the HTC Desire HD - using ace will kill your phone, use COOPER!!

5 - Download GAPPS (market etc) from Here

6 - Reboot into recovery, perform factory reset, wipe cache partition, and wipe dalvik cache (from advanced menu).

7 - Select update from .zip and select the Cyanagen ROM file. Wait until done then do the same with the Gapps.

8 - Reboot phone and VOILA! You have the official CM 7.2.

Notes

This is a nightly build so there are a few bugs. These are as follows:

1- Torch does not work
2- Screen does not come back on after a call (goes to main menu)
3- When WIFI is on the menu and back buttons blink when screen off
4- some people say FM radio does not pick up UK stations (mine does tho)

Nightly builds are released every now and then and just need flashing over the top - the idea is that improvements are made and bugs are fixed. At the moment we have a very stable, Very fast ROM which for a first nightly is fantastic. Battery is best for CM ROM i have used.

Please note although the battery is best for CM rom it will never be as good as stock. There is no task killer widget so be careful to end apps properly so they dont hog battery.

Uninstalling

If you want to go back to your stock ROM from this, there is a bit of a process involved. If you made a CWM backup you cannot simply restore it as CM7.2 uses the EXT4 filesystem and stock uses RFS.

To revert to factory settings you'll need to download your firmware from somewhere like sammobile.com or similar site. This site does not contain many carrier branded firmwares (like vodafone, 3 etc) so look for a program called checkfusdownloader.exe as this can find them if you made a note of what u need. And youll need ODIN and the cooper.ops file.

Flash using this guide HERE

then you will be able to revert to a CWM backup if needed or a Titanium backup of your apps.

As always if not sure make sure you find out the answer before attempting any of this as if phone bricks I cannot be held responsible.

Hope this is of use for someone!!:cool:
 
16/6/12 - Stable (final) release now available!

28/05/12 NEW NIGHTLY (RC3) RELEASED!!

Go to Cyanagenmod Downloads For the latest version. Most bugs should have now been fixed. Report any you find in this thread and I will feed them back. (please DO NOT) report bugs with 3rd party apps, or if you have used a modified kernel in anyway!)

Link for latest changelog CyanogenMod nightlies changelog for Ace

Update 22/04

Looking at the CM download page, there have been 2 new official nightlies. They should be adressing the bugs but i have not been able to test them as I have given my Ace to my Stepson as I now have a Galaxy Note. Will get him to test and report back to me!

UPDATE 16/04

Kolja Dumman (CM Maintainer) is working on Android and CM again. He has been asking a few to test new builds and is addressing the issues from the official versions. Slaid480 has also been given access to the Jenkins Buildbot (CM auto nightly buildbot) so expect a stable final release is not too far away!

Just come to my notice that the Nightlys below might not be acutally official. Stick with the post above if you want totally official. Will update as I hear more. The ones listed below do have less bugs thought!

New Nightly 04/04/12

HERE is the new nightly. Updates include:-

-Patched For Clear/Better Cam/recording and Better Sensors Too
-Fixed Some few Issue
-Faster than Old Nightly Builds

Torch now works
No button lights randomly coming on
Proximity Sensor Now works.

More updates as and when I find them.



03/04/2012 We have an official maintainer!!!

What does this mean? Well it means that Slaid (XDA developer) is now part of the CM team and will be pushing the updates in the form of Nightlys

One was released yesterday and another one on its way tonight. They will eventually be available from the usual Cyanagenmod page (See above) but for now head over to the original xda thread HERE

More updates as and when I get them!

Update : New release update-cm-7.2.0-RC1.

Having flashed this version last night. These Bugs Still remain:-

1 - Torch Does not work.
2 - Menu and back button light up randomly when Screen off and WIFI on.
3 - No Torch in Video Camera
4 - Proximity sensor issues when calling.

I have found no other bug. (as of yet) but will keep trying. I have noticed that these two official versions do away with the 3 major issues in the KANG versions.

1 - Lock onto GPS is very quick.
2 - Wifi Scans and locks quicker.
3 - Battery Drain is a lot better.

ROM manager is included and some on XDA have been testing it and so far no Bricked aces. look HERE and read the whole post. I personally have removed it with Titanium backup as dont trust it.

Will post any more updates as and when they come.

have a look at the guide at the top!

But in a nutshell. Root phone. Install Clockworkmod Recovery (5.0.2.6). Run Backup. Install Titanium Backup. Backup User apps.

When you want to reinstall - Download any gingerbread stock rom, odin and cooper.ops file (see above). Flash stock rom using odin. This will give you a stock rom with correct file system (rfs). Root and install cwm again. Run restore.

If need to run TiBu for apps (they should have been restored with CWM backup though)

Done!

Hello, I followed this guide and my phone got bricked when using the backup function in ClockWorkMod Recovery (downloaded from the link in the first post). I tried flashing it with Heimdall without success. Did this happen to anyone else ? How do I know if my phone is hard bricked just like what seem to happen with ROM Manager ? Thanks for your answers.

Did you sucessfully root before running the backup?

Hemidall is for the galaxy S series of phones (the ace is not one of them)

If you can get to download mode flash a rom via odin and it should bring your phone back to life. Good news is it sounds different from hard bricking (like with rom manager) as you can get to download mode.

Good luck
