(Latest release: stable v1.0)

Welcome to the ezGingerbread Rom and Development thread
Here we discuss building, testing, and patching a basic gingerbread build for the Dream Sapphire platform.

The goal is for this to be a reasonably bare bones build gingerbread build; Focusing on memory and speed performance.

Installation Guide (of Binaries)
While ezGingerbread remains as open source as possible this sections will provide some pointers to installing the latest distributed binary.

(The following is automatically done if installed via Rom Manager)
  1. Requirements
    EzGingerbread works on most 32b Dream, 32b Magic (MT3G), and 32a magic devices running 2.22, and/or 3.22 radios, and will auto detect the correct configuration on install.

    However the following configurations are optimal:

    32b Dream: Radio- and SPL 1.33.0013d are recommended

    32b Sapphire: Radio- and either SPL 1.33.0013d or 1.33.0013 (if the SPL is not already installed I recommend 1.33.0013d)

    32a Sapphire w/ audio plug (ie MT2.1/fender): Radio- and either SPL 1.33.0013d or 1.33.0013 (This is likely what you already have installed, if you don't have this and your phone works you likely you don't have a MT2.1/fender)

    32a Classic (no audio plug): Radio + any SPL (however 1.33.2009 or 1.33.2010 may be better) [Note 6.x radio will not work with this rom]

    Users of customMTD must have an 87 Meg system '87 2' is common. There is no need to flash the cMTD boot patch as the rom installer automatically patches the boot image for cMTD.

  2. Download Rom related files
    > The ROM: (md5: 2ae9f618b0650c98b9621b37ad7e8596)
    > GAPPS: (mirror)(mirror 2 -- dead) (md5: 6f9a6d27cce1f58be1f34f696212d326)
    > GPRS Patch (optional but recommended) (md5: fa259735ca394a650710e6b26673c91a)
    > Alt Launcher [Zeam] Completely optional, but for those that want a smaller launcher, or just intend to replace the default (Launcher2) anyway with a market download this may apply to you, Note its an older version, and the newer market version has been slightly unstable: (md5: 6416ec0efa15f92f3d36f6ec6b524a11)

  3. Language Port/Pack File

    If you use (German, English, Spanish, French, Italian, Japanese, Korean, Polish, Portuguese, Russian, and Chinese)

    These are contained in the base rom, do not download a language pack.

    If you use (Bulgarian, Czech, Danish, Greek, Finnish, Hungarian, Dutch, Slovak, Serbian, Swedish, Tagalog, Turkish, Ukrainian)

    These require lang pack 1: MD5: 37ee9cbf4f4c80a4b5fd96269332b853

  4. Copy Files to the phone

    Copy all the downloaded zip packages to your SD Card, Remember Ra-Recovery users must put them on the root of the sd-card.

  5. wipe or not to wipe, and other preparations
    > Users upgrading from
    GINGERBREAD-DS-Alpha-20110509-1, Beta builds, or the Gamma build

    There is no need to wipe as long as you wiped when you first installed one of these versions of ezGingerbread. You are however encouraged to uninstall SetCPU or other overclock software, and backup your rom before installing. (if the new built in CPU Speed function is not to your liking feel free to disable and re-install the 3rd party overclock software after upgrading)

    > Users New to ezGingerbread (upgrading from a different rom)

    You are encouraged to wipe before installing, however feel free to use Titanium or other utility to back up your application and application data to be restored after installation.

  6. Installing the rom
    flash in the following Order:
    > [If you need it]
    > [optional but recommended]
    > [if you chose it]

  7. Reboot
    Reboot the phone and wait for the screen to dim before interacting with the phone
    (First boot will take additional time; longer if you had many applications installed and are doing a no-wipe upgrade)

Tips and Tricks

Now that the system is installed I have some pointers to making the system as fast as possible, you may ignore these if you really must have something they don't allow but if the phone runs slower you know why:

Tip 1: Google Maps: If you can live without it the phone will be much more stable.. (Maybe using mapquest as an alternative) However if you really do need Google Maps note the newer versions require much more resources than the older ones.

If you must have google maps try an older version rather than maps 5+
Google Maps 4.7 (mirror) MD5: b8c558351949be97eb8703d1f4a05807 (download/place on SD card and install with File Manager)
Brut Maps based on Maps v4.6

Tip 2: Facebook: Well I can't say facebook was ever fast on our slow Dream, but the most resent versions run an "Upload Service" 24/7 in the background eating much unnecessary ram.. v1.6.4 is the newest version I know of without this behavior.

Tip 3: Apps2SD, well best to keep apps you want to use frequently of quickly on the system, but to enable Apps2SDext if you have an ext partition here are the directions:

> goto settings->Applications->Development
> Check SD-EXT
> Reboot
> Now you can use the Manager Applications screen to move apps to/from sd-ext .. if you want sd-ext to be the default install location choose it in Settings->Applications->Preferred install Location
> Data2sd will move all your application data to the sd-ext partition.. this will significantly slow down the phone thus best to leave unchecked.

Tip 4: SuperUser
The system by default prevents the update of superuser or anything signed with the same key (such as superuser elite); to temporary lift this restriction goto Settings->Applications->Development and check Update Superuser.

This will allow superuser to be updated, superuser elite to be installed/updated until reboot.

This ensures no application can change Superuser.apk on your behalf when you do not expect it thus can't grant themselves superuser access.

Tip 5: EzGb Extras
Settings->EzGingerbread Extras

This menu has historic "Spare Parts" funcitons, as well as other performance enhancements.

> Configure PowerWidget allows you to configure the powerbar widgets, when you are done configuring either reboot, or rotate the display to re-set the widget and see the update

> Incoming Call TouchUI - enables the slide to answer/end calls when a call comes in, rather than only being able to use send/end hardware buttons

> Busybox NTP Cliemt - If your phone is not keeping time, even with the sync to network time enabled, checking this may help keep the phone in sync with earthly time

> CPU Speeds, This lets you overclock and under volt, I recommend setting Min speed to 128000, leave Max screen off 480000, and max screen on may either stay 528000, or very slightly overclock to 537600. If you want the settings to apply after your next boot tap "Apply On Boot" if you have problems with the settings, before the screen turns off after boot enter this screen and tap "Reset CPU Settings" before rebooting again.

> Compcache RAM Usage, sets the amount of compcache, keep this as low as possible but not so low background services keep restarting.

> Use KSM Module, this may improve ram usage if checked, however may also slightly increase CPU usage and reduce battery life (all three results are very slight and thus hard to notice) no restart is required so test when/if it works best for you

> Window/Transition animatinos, since froyo animation times have been increased.. many find speeding these up make the rom feel more responsive as they are historically used to.

> End button behavior: choose "go to sleep"

> Haptic feedback/Compatibility Mode .. most will leave these alone

Tip 6: Surface Dithering:

Well this is a trade off [Settings->Display->Surface Dithering] if its checked the display may loose some more frames than if unchecked.. but some people rather loose the frames than see the artifacts left by skipping the dither, choose your poison and reboot

Tip 7: sync: disable what you can

Go into settings -> Accounts &sync
Tap your Google Id. Unless otherwise needed, unchecked Sync Picasa Web Albums, and Books
If you have Google plus you may also wish to disable Sync Instant Upload.

Historic versions, and additional addons can be found below in post 2


Regarding kernels: If you are looking for stand alone kernels (sometimes there is an update between official releases; or for use in other roms):
See the Stand Alone Kernel Post

The Stand Alone Kernel Post contains both the ezgb-2636 kernels and links to the tags in github they are built from.


Developer's Guide (How to build ezGingerbread and the ezgb2636 kernel) is now on GitHub:

Includes instructions to fetch and build from source both ezGingerbread and its related kernel.

Additional non-open addons that may be useful

Zeam Launcher By cloakt(replacing Launcher2 on system, also reduced to MDPI only): 6416ec0efa15f92f3d36f6ec6b524a11) [updated june 26th, 2011]

The packages above include support for: de, en, es, fr, it, ja, ko, pl, pt, ru, zh and are recommended for most users

If however your preferred language is not listed above, this LANG PACK 1 will replace the above languages with support for:
bg, cs, da, el, fi, hu, nl, sk, sr, sv, tl, tr, uk

Please download the version matching the ROM you are installing (see: adtl. details)
Mobile Data GPRS Tool:

A tool to update GPRS settings form gprsclass=10 to gprsclass=12 (also enables dtm)

Most users will experience better mobile network rates if they flash and choose yes, however if you run into problems simple re-flash choosing no to revert to the ezGingerbread defaults,
This tool will likely work on most Dream/Sapphire roms, however as always best to make a backup first
(md5: fa259735ca394a650710e6b26673c91a)

GAPPS: 20110709 (Please note if you are using 20110502-CheckPoint or an older build you must use gapps 20110205) (mirror)(mirror 2 -- dead)
MD5: 6f9a6d27cce1f58be1f34f696212d326
Cleaner 2.3.4 gapps package, recommended over 20110508b. Restore from Google corrected in this package, Talk2 has been replaced with the original talk app due to incompatibilities with voice/audio chat. However you may manually install it if you wish to use the newer interface w/o the newer features. While not 100% support of all languages, core apps support more languages in this package. Mirror thanks to SilentTweak.

GAPPS: 20110508b (Please note if you are using 20110502-CheckPoint or an older build you must use gapps 20110205)
MD5: 475fbf654977af73f30e509cb4adb21c
Also see information about Talk

Previous GAPPS: 20110205 (mirror)
md5: 70ddd820738b902d9b9f9b109e8fad5a

Note do not install both 20110508 and 20110205

MDPI Facebook App: [] (outdated)
md5: 17cb43e88f42cdf513f2c7c960347f21
v1.6.4 is newer w/o some of the newest memory eating services get the apk from:

For additional gapps:
1) Log into your Google account
2) tap gtalk to make sure its running
3) install the gapps you want from market (some common ones):
You Tube
Voice Search
Google Translate

*Maps and Streetview may also be grabbed from market; however Maps v5.* appears to be very resource intensive and overwhelms our poor devices; therefore I recommend either installing MapQuest; and/or an older version of GoogleMaps example extracted from froyo gapp pacakges. This will provide a much better gingerbread experience both while running maps and while not running maps.

Brut Maps based on Maps v4.6
Google Maps 4.7 (mirror) MD5: b8c558351949be97eb8703d1f4a05807 (download/place on SD card and install with File Manager)

Apps2Ext: (Included in 20110529-1 onwards)
This enabled in Settings->Applications->Development->SD-EXT

Sim Toolkit:

A friendly reminder... One hopes users of this thread know how to wipe their device .. and if they fail how to see they missed something in logcat.. but if not Super Wipe because regardless of subsequent errors all of these do boot to the Launcher.

Other uses are free to post custom builds in the thread for reference and testing.
Note however all of the above builds were cleanly made from the repo without modification. (ie. you are getting the file produced by the build system)

For full credits check github; Many peoples hard work (particularly that of the CyanogemMod's team make this rom possible)

More boots very well.

Under android version it still says 2.2.1. Almost ready for a daily driver.

I hope this becomes CM7 someday

Edit: I seem to have battery life issues using pershoots 2708 2.6.34.*... Any other kernel I should try (that does not have usb unplug bug)?

Am I missing something?

Your work is fantastic btw! So nice you are continuing support for our old dreams

Not that I know much, did you check if you have the latest radio and SPL?

Did you get it to boot?

The first time i installed, it would not boot, I waited for like 15 minutes or so, then tried a different kernel, same thing.
Just to try it, I flashed the gingerbread alpha again, and tried one more time, and it booted up.

I did notice the first time I flashed it, the "progress bar" did not move at all, the second time I was able to see it move.

1. backup
2. superwipe
3. shutdown
4. boot to recovery
5. flash the alpha rom (do not reboot)
6. flash pershoot latest New SPL + Radio 2708 Combo
7. unplug USB and reboot

Let it boot all the way up and let it sleep on it's own.

Don't expect a fluid UI and don't compare it to other ROMs. It's not intended for public consumption.

Um.. setup is part of gapps .. we have not hacked gingerbread gapps to work yet on this.. so I'd not install whatever non gingerbread gapps you have.
