Frequently Asked Questions
CyanogenMod 10
Android 4.1.2 Jelly Bean for Motorola Defy and Defy+

Quote:

The FAQ has been updated with some information about the 2nd Boot builds with custom kernel thanks to the collaboration of the user sa3e1 who rewrte some parts of the FAQ. If you have any suggestions, corrections or some information to add, please send me an MP. For more information about JB please visit the Motorola Defy Wiki With JB Status


Before doing anything:
►Always start the procedures with 80% - full charge battery (if your battery die during the process, you can still go Mcgyver)
►Make a backup of your apk's (using Titanium Backup for example) and a nandroid backup from recovery.
►If you have any problem, don't blame CyanogenMod Team, Quarx, Epsylon3, the FAQ or whatever. This ROM works (except the known bugs), if it's not working for you, it's mostly because you used wrong versions or are doing something wrong.

► What builds are "2ndBoot"?

24.09 builds and before ► Normal Builds
10.10 builds and after ► 2ndBoot Builds

► Is this ROM for Defy (MB525) or Defy+ (MB526)?

For 2ndBoot Builds:

Both, since Quarx’s "2nd boot” builds we have a universal build with custom kernel supporting all Defy variants (Defy Green Lens, Defy Red Lens and Defy+). This means that the same .zip file works on the Defy green lens, Defy red lens and Defy+.

For PRE 2ndBoot Builds:

Defy Green Lens ► Froyo Kernel ► CM10-2012XXXX-NIGHTLY-mb525.zip
Defy Red LensGingerbread Kernel ► CM10-2012XXXX-NIGHTLY-mb526.zip
Defy+No Kernel Needed ► CM10-2012XXXX-NIGHTLY-mb526.zip

Don't know if you got green or red lens? Click here.


► I don't have CM10 and I want to install it, how can I do that?

Pre-steps:
► Your phone has to be roooted.
If this is the first time you install a custom rom (if you have stock froyo) you'll have to root your phone, install 2nd init (custom recovery), and some other things.

A little FAQ extracted from the Wiki for some 2nd Boot Builds doubts:

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 never 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.

► I already have CM10 and I want to upgrade to a newer nightly, how can I do that?

Automatic update: (Using Defy ROM Updater)
1) Go to Settings ► About phone ► Additional system updates OR open Defy ROM Updater directly from the app drawer.
2) Tap Check for updates.
3) Select the newer version.
4) Select Start Download.
5) When the download finishes, install it.

Manual update:
1) Go to Recovery
2) Wipe Cache and Dalvik
3) Flash the last .zip file.
4) Flash gapps (just if you have a newer version of gapps, otherwise, this step is optional)
4.1) (ONLY DEFY RED LENS WITH PRE 2ND BOOT BUILDS) Flash battery fix (if you don't, the battery meter will display 1%)
5) Wipe Cache and Dalvik (this is also optional)
6) Restart.


► Is this ROM stable and ready for daily use?
Yes. In fact it's stable as CM7. Make a backup and try it by yourself.


► What's the difference between Quarx and Epsylon3 versions?
The new "2ndBoot” builds with custom kernel are avaible only from Quarx.
There weren’t recent updates from Epsylon lately, so if you want recent updates, and custom kernel improvements use Quarx’s builds.

NOTE: Always use the last version!


► Can I flash an Epsylon3's build over a Quarx's one without wiping data?
Yes, you can. Just follow the steps as if you were upgrading from a previous nightly. I didn't test coming from Eppy's to Quarx. EDIT: You can also flash Quarx builds over an Epsylon one without wiping data.


► What is full HWA? Is this a good thing?
This article explains everything:
"...Contrary to what we’ve always heard, Android has had some hardware acceleration for drawing 2D UI elements since before 1.0. Many of the animations we see every day on Android have been hardware accelerated the whole time. All “window compositing” is done using GPU-based hardware rendering.
Since Android 4.0 we have “full” hardware acceleration. All UI elements in windows, and third-party apps will have access to the GPU for rendering. Android 3.0 had the same system, but now developers will be able to specifically target Android 4.0 with hardware acceleration. Google is encouraging developers to update apps to be fully-compatible with this system by adding the hardware acceleration tag in an app’s manifest.
But hardware accelerated drawing is not all full of win. For example on the PVR drivers of devices like the Nexus S and Galaxy Nexus, simply starting to use OpenGL in a process eats about 8MB of RAM. Given that our process overhead is about 2MB, this is pretty huge. That RAM takes away from other things, such as the number of background processes that can be kept running, potentially slowing down things like app switching..."



► So, CM10 has full HWA? How can I enable it?
Thanks to the work of our developers on CM9, we have full HWA since the first alpha of CM10. HWA is enabled by default on CM10, so you don't have to do anything. However, you can select in which apps you want to enable it, with the HWA Selector, this app is preinstaled in all nightlys and it's easy to use.


► I'm on CM10 and a lot of apps give me FC and don't work properly
Make sure you have done a correct and clean instalation. Try wiping cache and dalvik.


► Why Google Now doesn't work for me? Why I just get regular google search?
That's related to the country you come from
USA ► pictures, knowledge graph, etc.
All the rest ► only normal google answers you also got from the website.
One solution is: In the search app, press Menu ► Go to Settings ► Privacy and accounts ► Search on google.com (activate this) and Location & Google search (deactivate this).
If this doesn't work, set your phone language to English.


► Why are some apps duplicated?
Make sure you flash the lastest Gapps or use a file explorer for root (as Root Explorer), go to system/app and delete duplicated apps (gallery and camera are more common)


► Why can I use Defy+ (MB526) builds on Defy (MB525) with red lense and what are the advantages? thanks to G00fY2
Because Defy+ has same camera as normal Defy with red lense, you can use its Gingerbread kernel and the MB526 builds. With green lense Defy you have to use Froyo kernel and MB525 builds to have working camera. But beside the use of 4 instead of 3 Vsel CPU steps there are no real advantages in using GB kernel. Both are based an 2.6.32.9 Linux kernel. Also you have to install a seperate battery fix, when using Defy+ build with normal Defy, because it has different battery size.


► I lose my data connection every time, is this error related to this rom?
No, it's a common bug related to others roms too. Check this post.


► I've just installed a new rom, and my battery indicator suddenly drops, is this a bug? Do I have to re calibrate it?
That's not a bug. Battery always show wrong percentajes when you flash a new rom. Wiping battery stats will not make any difference.
The solution is simple: You don't have to do anything. Charge your phone to 100% and wait one cicle of charge. Your battery stats will correct automatically. Your system always automatically "wipe" the stats when you charge your phone.


► How can I overclock and undervolt my Defy? And what are the advantages?
You can make your phone faster and your battery last longer. Check this article.


► I have problems with WiFi connections, my network get disconnected.
Make sure you don't have the "Avoid poor connections" option enabled. Go to Settings ►WiFi, press the menu button ►Advanced and uncheck Avoid poor connections.


► How can I change the DPI and keep play store compatibility? NEW

You'll need an file explorer. I recommend Root Explorer

1) Open Root Explorer
2) Go to /system and make sure that in the top says "Mount R/O". That means that the /system is mounted as R/W.
3) Long press on build.prop
4) Open with ► Text Editor
5) Scroll down until you see this line

Code:
ro.sf.lcd_density=240
and change that number for anyone that you want. You can try different numbers, I recommend 220, or 200.
This is how the line should be:

Code:
ro.sf.lcd_density=200
6) Menu ► Save changes.
7) That's it, when you reboot the resolution will be changed.


IMPORTANT: In order to fix the market compatibility, go to stable recovery and flash the right patch. DOWNLOAD


I'll keep updating this thread with your contributions, please feel free to correct me or suggest new questions.

yes, but the op of that thread just have the instalation instructions. The idea is post here the same questions that are asked over and over in the development thread.

I did this for helping some users, and i'm sure some of them will find this useful.

Thumbs up
Very nice!
Just some corrections:
Quote:

5) Flash CM9 Kernel (JUST FOR DEFY RED LENS USERS)
5) Flash CM7 Kernel

Never flash a kernel after the ROM, Epsylon said this long time ago, because you can revert some changes made in the ROM. You just have to flash the kernel BEFORE the ROM.
Quote:

- Why are some apps duplicated?

This happens when you flash and old version of Gapps, if you flash latest versions this bug is not present.

And something i want to add to the OP:

If you flash this ROM on Multiboot (on your SD card) you WILL experience lag, flash it as main system before come here to complain about that.

Thank you for your work!

On the other hand, when I tried to do it without the data wipe, the OS was very slow and applications stopped responding often. After wiping it completely, it's fast and snappy. So YMMV a lot, and I recommend using SMS Backup and Restore[ and doing the factory reset.

4) flash gapps
5) wipe cache and dalvik
6) restart


Make sure you flash the lastest gapps or use a file explorer for root (as Root Explorer), go to system/app and delete duplicated apps (gallery and camera are more common)

no need to flash gapps every time update the nightly
or put a (....) and write "only you have an update for it"
a noob will flash a gapps every time update the nightly
ps. to many wipe cahe and dalvik
one on the begining is enough
