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!!
