SlimJB4.3 for Canadian Samsung Galaxy S2 HD LTE (SGH-I757M)

[COLOR="red"][B][SIZE="4"]*** Disclamer ***[/SIZE][/B]

THIS ROM IS FOR THE CANADIAN SGH-I757M ONLY... DO NOT FLASH IT ON ANOTHER DEVICE!

By flashing this ROM, you are voiding your phones warranty (Unless you return it
to complete stock which is possible, but beyond the scope of this thread). You
also agree that I will in no way be held responsible in the event that your
device becomes bricked (Not likely to happen). In addition, you are responsible
to take the necessary backups of your apps, data, sms, contacts, calendar events, etc.

If you agree, then please continue on ;)[/COLOR]

[COLOR="red"][B][SIZE="4"]*** NEW RECOVERY REQUIRED ***[/SIZE][/B]

Due to the addition of user control in Jellybean 4.3, you are required to update
your recovery to a supported recovery. As of this writing, the latest available
version is CWM6.0.3.9/Philz6.07.9 for the SGH-I757M.

If you flash the new ROM with the old incompatible recovery, you risk loosing
your sdcard under a bunch of subfolders.[/COLOR]

[COLOR="red"][B][SIZE="4"]*** NEW RADIO FIRMWARE REQUIRED ***[/SIZE][/B]

As of SlimBean4.2, ICS radios (I757MUGLH2) are no longer supported. You must download the new JB radios (I757MUGMC5).[/COLOR]

Introduction

It's finally here :-D SlimBean4.3 (Android4.3.x) for the Bell Canada Samsung Galaxy S2 HD LTE (SGH-I757M). Among the most notable new features are new adreno graphics drivers with triple buffering (this is project butter). This is the latest SlimBean4.3 and has all of the features of a SlimRom that you've come to love. Don't forget to download the special gapps package to get the full SlimBean experience while using "The Real Dark Slim" feature.

What Works

* Phone
* Wi-Fi
* Mobile
* GPS
* Bluetooth
* SMS/MMS
* Data Usage
* Camera
* BLN Notification (Enabled in Advanced Device Settings)
* VM Notification
* Youtube Overlays
* init.d is fully supported

What Doesn't Work

* I experienced an incompatibility with some of my existing mp4 media files and when gallery tries to load them they cause a soft reboot. Loading these videos into the gallery media player using a 3rd party file manager seems to work without issue, it is the loading of the preview in gallery that causes the phone to crash.
Solution: The solution is to use a file manager to move the mp4 files to a new directory and add a ".nomedia" file to that directory so that when browsing photos in the gallery, it does not try to load the offending mp4 files. You can still view these mp4 files, but you must open them with a file manager directly into the video player instead of using the gallery to access them.

* The camcorder records just fine, but when playing back the video, it's just a distorted video. Audio is fine, and I have not tested video with a third party app. If you test one and it works, please post that here so that others may benefit from your findings.
This seems to have been fixed as of the 20140121 build

* The latest Google Drive seems to be missing classes and will not open. This may be due to a missing content provider or may be a bug with the Google Drive app itself.
Solution: The solution for this is to uninstall the latest version of Google Drive, then go to Settings -> Security and enable Unknown Sources. Then open the Play Store and turn off automatic updates or it will end up overwriting the older version and you will be left with a non-working Google Drive again. Once all that is complete, download and install this Google Drive instead:

com.google.android.apps.docs.apk (8.4MB)

Pre-Installation instructions

1) Download to your sdcard, the new CWM6.0.3.9 or Philz Advanced/Touch Recovery flashable zip which is compatible with SlimBean4.2/SlimBean4.3
2) Enter your existing CWM Recovery
3) Install Zip From sdcard
4) Select the CWM_RECOVERY_6.0.3.9_I757M_20131005.zip (or the Philz one) that you downloaded to your sdcard
5) Flash the new Recovery
6) Go back to the main recovery menu and go Advanced -> Reboot Recovery (This might not actually reboot you into recovery, you may have to do that manually by turning off phone and using 3-button combo)

Now that you have the new recovery flashed to your device, you can continue to install this ROM.

Please be aware that the new recovery detects your sdcards (internal/external) in a different way. Your internal sdcard is recognized as /storage/sdcard0 and your external sdcard is recognized as /storage/sdcard1.

Installation instructions

1) Download the Rom and Gapps (Use only the Gapps downloded from this thread. It is customized due to our small cache partition)
2) Enter CWM
3) TAKE A NANDROID BACKUP
4) Wipe Data/Factory Reset
5) Format Cache
6) Advanced -> Format Dalvik Cache
7) Mounts and Storage -> Format /data,/cache and /system (Required for a clean flash)
8) Flash the Radios
9) Flash the ROM
10) Flash the Gapps
11) Reboot Phone

NOTE: If you are using Philz Touch/Advanced Recovery, you can replace steps 5 - 7 by selecting the "Clean to install a new ROM" option.

FAQ

Q. Why is my screen flickering?
A. There is a bug in this ROM where the board can't decide whether to display the frames with the cpu or the gpu, thus the flickering while it resolves the issue. To fix it, disable HW Overlays in Developer Options. There is a script that has been included with this ROM in the init.d that sets that on every boot so you shouldn't have to.

Tips and Tricks

Use the Bell Flex APN. You can select it by going to:

Settings -> Wireless & Networks -> More -> Mobile Networks -> Access Point Names

This helps fix some issues with VPN and some other system services.

Logcat what is it and how do I get one?

A logcat is the system log of events that occur on your device. This log provides the developers with some useful information pertaining to crashes and other bugs you may encounter while using the ROM and/or apps running on the ROM. Getting a logcat is generally a very simple thing. Just open your terminal emulator on your phone and type the following commands without typing the $ as it denotes a command on the command line:

$ su
$ logcat -v long > /sdcard/logcat.txt

The first command above will ask you to grant superuser permission to the terminal emulator which you must accept. The second command will create a file at the root of your sdcard called logcat.txt and then start writing the logs to this file. Since the logcat is a continuous function, your terminal emulator will not return you to the command prompt after the second command as it will continue to write logs until you stop it by pressing the x to close the emulator.

If you are experiencing an issue with an app, then you need to do the steps above to get the logcat recording, then press your home button so that you don't close the emulator, but put it in the background. Then you do the action that causes the bug to occur and then open the emulator and terminate it to stop the log from writing. this ensures that the error is located somewhere around the end of the log and makes it easier for us to spot

What is dalvik-cache and why do I need it?

To explain dalvik cache, you must understand how an app is pieced together. An apk (android app) is like a zip file and contains a bunch of files inside. Two important files to note are the resources.arsc and the classes.dex files. They are compiled versions of the resources (images, sounds, xml files) and classes (source code files) of the app. When android boots into a ROM for the first time, and everytime you install an app, the system performs an optimization called dex optimization which means that is pulls the dex file out of the app and places it into what is called your dalvik cache. The system can then pre-load these dex files and allow the app to start quickly.

Dalvik cache is stored in two locations, at /data/dalvik-cache for user apps and at /cache/dalvik-cache for system apps. We unfortunately have a very small partition for /cache, only 100MB and this sometimes causes a side effect on first boot where it fills up to much with apps that only ever run on the first boot to setup the system and then other dex files cannot be written to the /cache partition which causes them to Force Close (FC). The trick in this situation, is to bear through the FC messages to get the system to the home screen, then reboot into recovery and Wipe Dalvik Cache from the Advanced sub-menu. This will delete all the dex files in both locations I mentioned above and will force the system to regenerate them upon reboot, and this time, those 1-time running apps don't start up and don't end up being optimized which allows the necessary dex files to be created for the apps that were FC'ing.

I have moved what I could from the system partition to the data partition to spare some extra space on /cache but this still sometimes happens, especially as the ROM's get slightly bigger every new major version.

titanic_fanatic, I just bought a pawned SGH-I757M and flashed your ROM on my device.

I love it, but there is one problem with my device. I find that the AMOLED screen is much too warm for my eyes. I know that CyanogenMod has in color modifier sliders but in this case, the kernel doesn't support it.

Is there any chance you may point me in the right direction in order to get this feature working? Or am I at lost with the SGH-I757M?

Thank you very much for your hard work, much appreciated!!!

Hey

Is this any different from the Cyanogenmod 10.2 iteration other than aesthetics? Does the battery and performance offer more seeing that it is supposed to be a much smaller and compact kernel?. I really have to urge to flash this, but I don't know if its worth my time considering I have already flashed CM10.2 recently and am very happy with it. Thanks!

I'll add back the mdnie settings. They are supposed give you control of the temperature

Only difference is in features and it's been slimmed down.Other than that, it's the same ROM. I just posted it for those who like the slim features check this page out for the list of slim features:

Hi Shouldn't this be in the development forum

I've only posted or ROM's here since that's where dsixda was told to post them back when he started with this device. If the mods would prefer I post them in the dev section, I'm more than happy to oblige

Amazing

I just flashed it, its amazing! Especially "The Real Dark Slim"! However, I did notice Google + doesn't work properly asking me to re install it at the play store. Had to uninstall using Titanium Backup and then install it back via app store, not sure now whether it has the the real dark slim feature integrated in google +. Other than that, it's really smooth so far Great port.

UPDATE: Google drive also doesn't work as it force closes continuously even after wiping dalvik's cache. I'll try redownloading the gapps tomorrow, might have a corrupt downloaded file.

 

[manfromgta]

I Fashed latest slim as well. It is running really well so far. I had the same issue with Google+ until I uninstalled using TB then reininstall from play store.

Can confirm issue with Google+..

Thank you t_f for looking into mdnie. Also, flashing the unmodified lock screen handle available on Slim's website did not work, I still see the Slim logo. Aaah I wish I had time to figure out the android build environment.. I mean its probably just ant lol

I noticed while testing the latest slim that hw overlay is disabled by default. Is this by design or necessary with this rom? I know this issue is addressed in your other ROMs but not sure about this one. BTW with fairly heavy use I am currently at 40% battery over 20 hours. Quite acceptable.

It is intentional. Disabling the hw overlays is a performance hit, and it seemed that slim didn't need that hack because the overlays are working correctly

I know, the latest ROMs are running smooth and battery is much better since I tweaked the kernel for both.

I'm also really enjoying my new computer so much that I'm playing with paranoid android too. Got it booting with a bunch of hacks and to my suprise, it's running quite well. I'll post that after I test it more and clean up the build process. Then we have choice of which ROM too use. That was the problem before, no choice strange though, there is no branch for kk in paranoid android's repo.

Just a word of caution to everyone using philz latest 6.07 cwm recovery. There is a know issue where the update-binary has now been updated as of kk and the recoveries built with kk like the new philz 6.07 are now giving assert errors (error 7).

There are two ways to fix this:

1) Revert to the older 6.01 version of philz.
2) extract the updater-script from the rom zip file, delete the assert lines and replace the old updater-script with the new one.

If you're new to all this, or consider yourself inexperienced, I recommend you go with option 1 and revert to the older philz as it's a less risky method of doing things

Here's the link to the older philz 6.01. You can use either the 6.01.0 or 6.01.2.
