Motorola Defy/JB status
This page is intended to help keep track of the state of the many JB builds by Quarx2k and Epsylon3.
Defy/Defy+ XDA Threads
To download JB CM10 Quarx Builds (Defy/Defy+ GB Kernel) see this thread: 
For BUGREPORT all versions and kernels see this thread: 
Limit the number of described builds here and remove older builds as they get replaced by newer just as stable builds.
Defy/Defy+ CM10 helping locate issues with nightlies
There is a lot of people reporting issues with nightlies based on little information and with very little information to help the developers squash the bugs.
So when you want to report an issue with a nightly build, first check if others have reported this bug? If it is reported, try to be specific when adding your information. This is also important it none have reported it yet - Furthemore Then you should make sure that it really tied to the nightly. You can help the developers immensly by trying to narrow down what causes the bug to appear. If it's not reported yet, chances are that the bug requires a special setup to be seen.
On the Jellybean thread I have seen the following types of apps/scripts do more damage than good:
- Launchers other than Trebuchet (the standard one) can cause FC's, lag and higher battery consumpion.
- Apps that takeover/extend lock screen (MIUI - cause lockscreen not to switch off).
- scripts that change kernel settings (speed optimization scripts from GB kernel caused lag on 2ndboot kernel).
- High battery consumption because of apps that changed the way they access the internet.
Guides, How-Tos & Tutorials
Upgrading to newer build
- Download new nightly zip
- Reboot to recovery
- Install Nightly Zip
- Wipe Cache
- Wipe Dalvik
- Install ICS Battery Fix (ONLY RED LENS MB525)
- Reboot phone
Right after an upgrade the phone might react a bit slow for some time after the upgrade. It may also use more battery. So give it a day before reporting lag and battery issues.
If going to a different build, e.g from CM9 to AOKP. You might need to wipe data as well as cache, dalvik cache.
Upgrading from CM9 to CM10
It can work without wiping data. However if you do have stability issues or bugs not mentioned try wiping data Remember to make backup before wipe You will need new google apps for CM10 they take up more ROM than the google apps for CM9 - There is a Minimal gapps zip on XDA
Upgrading to 2ndBoot Releases
If upgrading from previous CM10 release -
- Download new Nightly Zip
- Reboot to recovery
- Install Nightly Zip
- Install kernel update if available (for instance the update_for_11.10_v2.zip for 11.10 nightly)
- Wipe Cache
- Wipe Dalvik
- Reboot phone (takes some time for 1st Boot)
- For 1st upgrade to CM10, Wipe Data off the phone completely through Recovery before installation (Remember to do a BACKUP!).
- Upgrade from 11/10 to 12/10, just install like any other CM10 release. If upgrading from any other release you need to install 11/10 before 12/10.
P.S - For 10/10 release - http://forum.xda-developers.com/showpost.php?p=32617972&postcount=9308
- Where is the Package for Defy (MB525) ?
- From 2ndBoot Release there is only 1 package for both Defy & Defy+.
- Do I have to install the Custom Kernel separately ?
- No, the Nightly Zip already includes the Custom Kernel, but there might be a newer kernel released without nightly. i.e. there is a newer kernel (update_for_11.10_v2.zip for 11.10 build)
- Must we change the Boot sequence to 2ndBoot in 2ndInit ?
- No, the Upgrade does this for you.
- Is a Data Wipe required ?
- Only if you are coming from builds other than CM10 (Quarx's). There is no harm in doing a Data Wipe otherwise also.
- My phone lags after Boot up.
- Its a bug in the Custom Kernel. To solve just turn off Wifi/Internet, Screen Lock & keep idle for a couple of mins.
Improving battery life
There are several tricks that can limit battery drain. Some tricks will however limit the functionality (I.e. activating flight mode) where as others actually just makes the phone run "smarter". Thus this section is divided into two. One section with tricks that don't limit functionality and one section that limits the functionality
Tricks and tweaks that helps without limiting functionality
Several things that could improve battery life:
- On Jellybean with custom kernel(2ndboot), lower zRAM or switch it off - It helps to make more RAM available to Apps by compressing data in memory, but does so at the expense of battery usage. So it's a compromise to be made.
- Best CPU settings? And how to set them? (e.g. using "SetVSel" to adjust max CPU levels based on battery state)
- Use gingerbread builds together with the 4.5.2-109_DHT-22 kernel to get deepsleep. (for bootloader<6 only!)
- Use ported Droid X CPU governors  (lncluded in latest epsylon builds)
The tricks in this section is all the battery tricks that increase battery life on all builds, but also limits funtionality.
- Lower screen brightness and/or use auto brightness (beware not to set custom levels so low the it's completely unusable!)
- Set screen off timeout low (e.g. 15s)
- Do not use live wallpaper and avoid desktop widgets
- Disable mobile data
- Disable 3G
- Disable wifi
- Disable gps
Buttons can be added to Notification bar for quick control of these. Many settings can be controlled easily/automatically with power control applications from the play store, including based on location (e.g. disable Wifi when away from home/office, etc.).
- Install LBE and limit applications access to hardware
- Use a battery statistics tool to monitor patterns and usage, e.g. "Battery Monitor widget" (by 3C). https://play.google.com/store/apps/details?id=ccc71.bmw
- Reboot phone to clear most running apps (before removing charger)
- Identify apps that autorun (e.g. at boot) and disable unnecessary ones. "Gemini App Manager" (SEASMIND) is good for this. https://play.google.com/store/apps/details?id=com.seasmind.android.gmappmgr
- Use a process monitor like "OS Monitor" (EOLWRAL) app, to check which processes are running. https://play.google.com/store/apps/details?id=com.eolwral.osmonitor
- Use a CPU state checker like "CPU Spy" app, to ensure the phone is going into deep sleep. https://play.google.com/store/apps/details?id=com.bvalosek.cpuspy
- Wake locks: identify any apps that can prevent your phone from sleeping.
- Synchronisations: reduce sync frequency or set to manual (check accounts, e.g. for email, calendar and contacts syncs)
- Scheduled processes: change frequency or disable any unnecessary, e.g. AV scans, Titanium backups, etc. (and make sure they don't happen while on battery)
- Application Updates: disable any unnecessary auto-updates in app stores.
- Background user processes: hold down Home key (from desktop), and swipe any unnecessary to close.
- Enable "close on long-back" (kill apps when finished with them).
- Network access: use a firewall (e.g. "DroidWall") to block apps unnecessarily using the network.
- Advertisements: use a blocker, like AdFree and browser plugins like Ghostery & AdBlockPlus to limit additional network requests (check this doesn't breach your app usage permissions)
- Ensure battery is fully charged by checking charge mAh (ignore battery 100% status if still drawing a charge current).
- Consider aftermarket high capacity batteries (e.g. Mugen)
- Use profiles to quickly manage settings.
