[ROM] [SGH-I757M only] CyanogenMod 9

CyanogenMod 9 for Samsung Galaxy S2 HD LTE (SGH-I757M)

THIS IS AN UNOFFICIAL BUILD OF CYANOGENMOD 9 BUT CAN STILL BE USED AS A DAILY DRIVER.

CyanogenMod is an open source replacement firmware based on the Android mobile operating system for smart phones and tablet computers. It offers features and options not found in the official firmware distributed by vendors of these devices.

Bell Canada released the Galaxy S2 HD LTE (SGH-I757M), which is a slight upgrade from its original Galaxy S2 GT-I9100M released the summer before, with now a bigger display and HD resolution. Since Bell hadn't released an ICS update yet, I have ported CyanogenMod 9 (stock ICS / Android 4.0) to the SGH-I757M.

NOTE: I was told by mods to post this thread in this General forum because it's not an I9100.



(Screenshots attached below)


What works:

Pretty much everything for daily use. Click below for details.


What doesn't work:



Download:

WARNING! Do not flash this to a different device model from the one it's meant for. It will not work with the other Galaxy S2 iterations, so don't try it with the Bell Galaxy S2 I9100M (non-HD). DO NOT flash it on the Asian variant of the GS2 HD (SHV-E120) either, as it uses slightly different internal hardware - the ROM will be unstable and the phone component will not work. If you are sure you have the CANADIAN Bell Galaxy S2 HD LTE (SGH-I757M), then click on the button below:

(For questions about CM9 for the SHV-120L, contact skysbird on Twitter or GitHub. I will not discuss that device in my thread.)

Full instructions for installing:

Download the necessary files:

1) Ensure you have my latest ClockworkMod (CWM) Recovery image for the SGH-I757M. Please refer to this thread for details. NOTE: The original released version of CWM for this device is not compatible with the CM9 ROMs, so update to the latest one please.
2) Download the CM9 ROM from the SGS2 HD LTE / cyanogenmod9 folder found at the big Dev-Host link above.
3) Download the Google Apps (gapps) file from the SGS2 HD LTE / cyanogenmod9 folder found at the link above. The Google Apps are flashed separately from the ROM due to legal requirements (proprietary files). They include Gmail, YouTube, Play Store, Maps, etc.
4) Optional: Download the stock Bell ICS modem (MUGLH2) from the SGS2 HD LTE / factory images folder. You should skip this step if you had earlier flashed the stock Bell ICS update, since it contains that modem/baseband (check your Settings-->About screen to verify the Baseband).

Back up your data:

1) If you're coming from a non-CM9 ROM, back up your apps and data with the Titanium Backup app if you wish. Back up your SMS messages with apps like 'SMS Backup and Restore'.
2) Boot into CWM (hold down power and both volume buttons, let go at the Samsung logo)
3) Enter CWM Recovery and make a Nandroid backup of your current ROM, just in case.

Now flash:

1a) If you have CM9 already installed and want to flash it again: In CWM - wipe cache, then go to Advanced menu and wipe Dalvik cache. Then flash the CM9 zip file.
1b) OR if this is your first time flashing CM9: In CWM - wipe data (factory reset), then flash the CM9 zip file TWICE.
2) Next, flash the zip file for Google Apps - it is recommended to flash this every time you flash a new CM9 ROM!
3) If you had also downloaded the modem, then flash that as well.
4) Reboot phone
5) If you have problems, read the FAQ below and ask questions in this thread if necessary. Please do not PM me about tech support.

Frequently Asked Questions

Q. I flashed CM9 after coming from another non-CM9 ROM, and I get errors or phone fails to boot.
A. Make sure you read the instructions in Post 1 for flashing correctly. If you still can't figure it out, go to the "advanced" menu section in the recovery menu and select the log output to see what went wrong. If it says you have an "assert" issue then you obviously have the wrong version of ClockworkMod recovery and you didn't follow the instructions.

Q. How do I restore my phone back to factory conditions so that I don't have a voided warranty?
A. Flash the stock Bell firmware (found at my dev-host link) with Odin. OR download the stock firmware by creating an account at sammobile.com and going to the Firmware section (search for SGH-I757M); then flash it with Odin.

Q. I'm not getting LTE (4G) speeds on my phone with CM9
A. By default the ROM is set to normal GSM (3G/HSPA). You can change it under System Settings --> More --> Mobile Networks --> Network Mode --> LTE/GSM. For some providers like Rogers you may need to manually add the APN for the LTE network as well. To verify you have LTE working, you'll see the "4G" icon on the notification bar. In addition, you can run the Speed Test app to ensure you get LTE download speeds like 25Mbps instead of 4 Mbps. Of course, all this depends on whether your location has LTE towers within its vicinity.

Q. Why do my buttons light up when I get a notification?
A. By default the Backlight Notification (BLN) is turned on. You can disable it under System Settings -> Advanced -> Sensors.

Q. The NFC options can be enabled in the Settings but why doesn't Android Beam work?
A. The device seems to not have the hardware support. The same problem happens in the stock Samsung firmware. However, the online user manual mentions the use of Tags, although when I tried with both stock Samsung 2.3 and CyanogenMod 9 they couldn't read the NFC tags (at the same time I was using an Xperia S and that was able to read the same tags fine). There is discussion going on in this thread stating that we may need an NFC-enabled battery and/or special battery cover. Click here for some debug info from the phone when we turn on NFC.

Q. If I power on the device while the charger is plugged in, it does not turn on. I need to pull out and re-insert the battery to start it again.
A. This is a known issue in CyanogenMod 9 and in AOKP, not just this ROM. You could also try unplugging the phone and holding down the power button for several seconds to turn it on.

Q. How do I access internal storage and also my micro SD card?
A. Internal storage is under the folder /mnt/emmc; micro SD is under /sdcard.

Q. Does FM radio work?
A. No, this device does not have FM radio hardware support.

Q. My battery life sucks.
A. Not my fault, I did not do some geeky tweaks or overclock your phone. The device itself has a crappy battery and you'll notice the same issues in stock. Click here for some battery-saving tips.

Q. I am a newb but want to help out with ADB and/or debugging an issue, how can I?
A. Read here. Also see the following posts on how to get the sources to build the ROM.

@johnnyjb that output doesn't really help. It didn't show you flashed anything. Did you get that after a reboot? Use adb to grab /tmp/recovery.log or /cache/recovery/last_log right after flash.

If you are flashing from an external SD card and getting incomplete flashes or it's stuck at boot, then you might have a corrupted SD. This happened to me.

I've watched the development for this device since day one and it's pretty remarkable how quick we went from struggling to find a root method to having CWM and now CM 9. Much thanks to dsixda!

Now down to business. I remember in the original thread someone confirmed that the light sensor was working however, running the latest revision I don't seem to be getting any response from the light sensor, I've tried a few sensor monitoring apps and the brightness wont adjust when set to "Auto Brightness". Has anyone else experienced this?

Set it to lowest brightness manually, then set to auto brightness. You should see adjustment to normal brightness eventually. I do notice the sensor is a bit slow on mine though.

jsr84 said:

I noticed a small amount of adjustment. I thought I would restore back to GB to compare the sensor using the same app and in GB the app reports the sensor as a "TAOS" sensor in CM9 its reporting the sensor as a "Sharp". In GB the sensor seems to react to different light levels were as in CM9 it wont respond to any light changes.

I know your plate has enough on in with regards to this port, but it was just something I noticed, I'm not even sure if its relevant.

Oh I know how to fix this, it's in the kernel. I'll get to it right away. I notice that the GB kernel has the correct model of sensor (TAOS) but I overlooked it when making the ICS kernel. Thanks a lot for the useful info.

I believe this will also fix the proximity sensor because apparently these 'optical' sensors are dual purpose.

I'll have a fixed build by the evening.

I noticed that both under Performance settings and using some overclocking apps on the market that the maximum CPU frequency is set to 1836 MHz, and cannot be changed(always reverts). Unless I've been misinformed isn't the default maximum CPU frequency 1.5GHz? If so isn't it a bit haphazard to have it set so high above the normal by default?

Click to expand...

I noticed that too and I wouldn't do that intentionally. In fact I don't even know how to overclock in the kernel! Not a big issue IMO, but I'll look into it when the big issues have been fixed. Thanks
