Guy, I'm fairly certain that our phones just use the same battery as the Infuse 4G.

I haven't tested this theory yet, but I do have a handful of Infuse 4G batteries en-route from eBay. So if you're willing to wait another week or so for me to test this theory, I'll report back, and hopefully that will be an easy solution.

By the way, "extended batteries", unless they're physically larger with modified rear backings (ie, the "double batteries") are rarely "extended". It's a marketing gimmick, and in my experience, it's a really GOOD REASON to expect that the battery will have a lower capacity than the original OEM battery from Samsung or HTC.

I've verified this ^ through testing the actual capacity of dozens of cells, but you can also verify it with basic logic. Fact:

1) Batteries are not expensive components for Samsung / HTC / the manufacturer of the phone.

2) Samsung / HTC / etc are constantly battling for the best battery life.

3) Battery capacity is constrained by physical properties (energy density of the battery chemistry used).

So, if someone could make a battery that was size compatible with the original Samsung battery, but held a higher capacity, why wouldn't Samsung have just done that in the first place? Samsung is one of the largest electronics manufacturers on the planet and they have relationships with everyone (humerously, even their competitors like Apple!). Do you really think Samsung couldn't source the "most extended" battery possible for use as the OEM pack? This is not like printer ink where they're counting on consumables to make back their money. Most people DON'T buy second cells for their phones, and those who do, generally don't buy from the manufacturer anyway. But people DO make decisions about the phone they'll buy based on battery life (which is always tested and reviewed based on the included OEM stock cell). So Samsung has every motivation in the world to use the highest capacity cells out there. In fact, they spend a lot of money to optimize hardware platforms to minimize power usage. Do you think they would just "forget to investigate" whether they were using the highest capacity cell out there?

When I tested a dozen or so of the most common Sensation batteries on the market, the bottom line was that basically none of them outperformed the original HTC cell, and that at best, a few roughly matched it. There was also no correlation (that's right, none) between "claimed" and "real" capacity. So, you might look at two cells, one claiming 2500mAh, and the other 2800mAh, and think "even though I don't believe either claim, the 2800 is probably better", but that thinking doesn't hold up either.

i have been using the Samsung Infuse 4G SGH-i997 battery ON MY I757M for 2 weeks now.
[Galaxy S II General] rhd-android:
Awesome! That's exactly what I ordered after comparing sizes, weight, and contact position. I thought they were identical.

There are a million of them available online.
[Galaxy S II General] CharlieMPK:
Yes, I can confirm that the Infuse battery does work with the i757. But I have noticed a difference between the two.

Infuse: The model number is GB/T18287-2000 it is a 3.7V Li-ion battery that runs at 6.48Wh with a 1750mAh rating. (2011.04.26)

SGH-i757: model number is GB/T18287-2000 it is a 3.7V Li-ion battery that runs at 6.85Wh with a 1850mAh rating. (2012.06.27)

^Hope this helps! :D

Hello fellow CM9 users. Today a bug in CM9 locked my phone apparently. I use CM9.0 on my SGSII.

I was calling someone and exactly as he was accepting the call, 1\2 second later the call hangs and as i then was looking onto the display, it was rotated to the right even though i was holding it upwards and it was totally hanging.

No reaction whatsoever to any key. After 10min waiting i finally removed the battery, inserted it again, the phone started and now my lockscreen is locked rotated to the right. I cant confirm my Pin-code this way to enter the phone, because the "OK" button is not visible when the lock-screen is rotated right and stuck there.

So what can i do to solve this and keep all my Data?

In the Clockwork-Recovery\Download mode i made a full backup and tried everything, wiping caches, dvalvik-cache, etc. No success.

Only resetting the phone to factory works and i can enter it again - however all my 122apps, pictures etc are gone which is a no-go. So i restored the backup again which works very good.

What can i do to solve this?

I was thinking about extracting the backup on my computer and deleting the Gyro\Tilt\Rotate Calibration data, repacking it and restore from it.

Does this work? If so which files to edit? Any other Solutions possible?

Thanks a 1000 times for all input

Best Regards Christian

Have you tried to wipe the caches and reflash the last build from SD-card?
[Galaxy S II General] chriss_android:
Yes i did. I tried reflashing of CM 9.0 aswell as CM 9.1 with the same result. The lockscreen is rotated right and stuck there.

Unfortunately my knowledge of the Android OS is not sooo deep, so i don't know which files to replace, to reset or even disable the screen-rotate feature, so i can unlock it again with my PIN-Code.

I have seen some people previously on some phone-forums "coding" or "packing" a zip for people with various "different" android problems, which they then could successfully flash from the recovery-mode or download-mode via PC, to reset/restore a certain feature of the Android OS.

Can someone do this for me? I use CM 9.0 Stable on a SGSII (GT-I9100)

NFC Antenna

So, I couldn't find my Bold 9900 but I came across a Curve 9360 that has the same style antenna.

I have affixed it to the battery cover and the contacts line up perfectly!

Now I just have to wait until I go out and find NFC tags to try it on.

Does anyone know the best way to test without NFC tags readily available?

I will post my results if I come across any tags today while I'm out.

Mobilicity Help 1700Mhz/ 2100mhz

Is there anyway to use this version of I757M S2 on Mobilicity in Canada.

I have unlocked the phone, I flashed 2.3.6 rooted frimware.

i also installed CW and installed and tried all the tmobile modems.

but no luck sometimes it picked up Mobilicity but when i dialed a number call just ended without ringing.

The closest i got to making it work was that it had

service but it was on roaming mode and that was on a stock modem.

I have also tried dialing *#2263#and selecting 1700Mhz band but still no luck

Can someone please walk me through this ? :rolleyes:
[Galaxy S II General] dmeinder:
You need to check if they use same radio bands as bell.

If they don't, sorry you'll be out of luck. If they do you have to register you imei number with them.

Help Please. Screen Broken.

Hi All, I have dropped my i757m :(

can use side buttons but the digitizer is shot as well as all picture onscreen.

If at all possible to use CWM to backup my internal card that would be very helpful.

does anyone have the latest none touch version of CWM for this build and are able to walk me through the button presses?

also if i manage to create a file, How can i get it off of this phone? need some billing info by monday if at all possibe.

Thank you for your time and help, VINCELDUB.

my usage of the rom

I have been using this rom for about 2 weeks or more now and I can say it is very stable and does do pretty much anything like AOSP. One thing to address. I have been having mic problems while calling and during the phone call. The second time around it works fine. I have also noted that the phone has to be really up close to the ear for the mic to work as if the mic relies on the proximity sensor. Anyone else having this problem or is it just me?
[Galaxy S II General] rohan00:
kind of a late response but yes i hav this same problem...light sensors dont work when set to auto...i just managed to get this phone and using this method to upgrade it

Unlock

I have a Bell Samsung Galaxy S2 I757M With Android 4.1.2, and I am looking to unlock it. I have had no success with any Google play unlocking tools. I just need clear instructions on how to do this with PC, cable etc. It is rooted, but I don't know where to go from here. Baseband version I757MUGMCS JZ054K build, non custom ROM
[Galaxy S II General] Titus_Andronicus:
I just installed this ROM on my I757m. I am enjoying it, expecialy the fact that the radio (ICS Radio MUHLH2) is working well with my GPS. The JB radio that I was using with CM11 didn't work with the GPS.

However, I am no longer getting LTE, just the HSPA. Anyone know is this is a known issue, or if there is a fix for this? Is there a different radio I can flash that will work better? Will the GB radio work with CM9?
[Galaxy S II General] Titus_Andronicus:
Fixed it. It was just turned off by default. I just turned it on in the network settings.

PLease where can i get the link to download the rom?
[Galaxy S II General] LVNona:
Awesome rom but waiting for stable release

Yesturday try your rom - Love it!

But after 30 min I get "banana" ;)

install google maps & google navigation. Start to use it in a way home and phone starts to get restart in loop...take battery out for few minutes - starts ok.

After thet camera - doesnt work at all.

And after that my calling phone stops to work - i can do phone call...but no sound and no mic. and if somebody calling me - no sound.

Try to reflash - doesnt help.

Need phone for work that's why reflash for older rom.

Any suggestion? really want this rom.

Thanks
[Galaxy S II General] dsixda:
If I had a suggestion then I would be a genius and have fixed it, I am not.

Are you using the ROM on an ES120 (Asian GS2 HD)?? If yes, then please don't post in this thread and confuse the Canadian users - the thread is meant for the I757. The ROM works on the ES120 except for phone and camera as you said, but I am not going to help with that.

[Galaxy S II General] dsixda:
Thanks for the info, I'll build a new version of CM9 on Tuesday with new files from the Galaxy Note. We'll see if that resolves any of the outstanding issues.

I'll be disabling BLN as it appears to have been broken with the fix for the capacitive buttons not turning on (which is more important than BLN, IMO).

There's something else that I noticed in the Skyrocket/Note sources which has to do with "Enhanced NFC". Not sure what it does but I've added it to ours as well.
[Galaxy S II General] dsixda:
In the meantime, please update your CWM to 5.5.0.4b (letter "b"). I've enabled the performance enhancement of SD card read/write. I'm not sure if that fixes any of the flashing issues however.

https://d-h.st/users/dsi
[Galaxy S II General] dsixda:
I am on my phone right now, but search the thread for my instructions on how to build CM9 for this device.

Kernel does not need to be modified for cam, I already know what hardware it uses for the front and back sensors. The front camera issue is likely in the lib files .. liboemcamera.so, libcamera.so, camera.msm8660.so... Some of those are built off properietary code, which is why the files are in the "vendor" folder in github (i.e. no source code is publicly available, so we have to instead copy the binaries directly from existing ROMs). However, there is a site called Code Aurora where people are working on open-source drivers for these MSM8660-based devices. You may find stuff there.

Keep in mind our front cam sensor is different from the one in every other GS2 variant (who all use the same front camera... weird), which is why we *might* need to build our own drivers or else wait for the Bell ICS update to get the working lib files. I would hold off on that for now and concentrate on the video playback issues instead.
[Galaxy S II General] dsixda:
I'm not seeing anything new in the above build. In fact, I have reverted back to the original set of files I had.

I'm uploading a July 3rd build as I type. It has updates for enhanced NFC, GPS utils (?) and Adreno drivers, and disabled BLN because it's broken, and increased the SD card performance in the kernel.

Nothing new for video playback and front camera, however.
[Galaxy S II General] TrainAss:
What is BLN?
[Galaxy S II General] deafened:
Big SUPER Thanks

I've been installing customer ROMs since my 1st month of having the i9000m from Bell (currently rocking ICS). I am constantly amazed by the work of developers who can put together a working OS while Bell lags behind trying to add their own crapware to an already beautiful device.

This ROM has everything I need for daily use. I had one random reboot when the phone was reinstalling my apps. Other than that, it's great to be back on ICS.

Thank you for your hard work.

Am I the only one who is having issues downloading the latest build from dev-host?

All other downloads off the directory are fine, but the latest build seems to stay at about 20 kbps download, which eventually leads to download timeout :/

They're upgrading their servers. Check their twitter feed.
[Galaxy S II General] B.Moreira:
As the post says the front camera doesn't work, but I decided to try it out anyways and caused the camera app to crash everytime it opens. :( So long story short don't even try to use the front camera or you'll have to wipe your phone and reinstall the rom again.
[Galaxy S II General] dsixda:
There is a way around that, you need to clear the data and something else for the Camera app. I successfully got it restored but can't figure out exactly how anymore.

P.S. Nice to see someone from edmonton.. I grew up there.

If someone wants to help out, here's something we need to crack:

I can't get Gallery thumbnails of video clips to show up. The preview pics are blank. This is the logcat when I go into a folder with two videos (one MP4, other 3GP):

[Galaxy S II General] markdexter:
hey dsixda just on my way to work, I came across this http://epiccm.blogspot.ca/2012/05/pictures-repair-and-cleanup-for-epic.html?m=1

doing know if it will help, maybe tonight I can play around with it, see if I can help
[Galaxy S II General] dsixda:
The actual problem is at the very end of the logcat, where it says the videoframe returned a null pointer. This means the video format is not supported (accodding to google) and hence it cannot generate a thumbnail preview of the file, since it can't open the video.
[Galaxy S II General] B.Moreira:
Hey dsixda, do you think you could add the Samsung task manager to the CM9 rom?
[Galaxy S II General] dsixda:
No.

There are more important things at the moment like getting CM9 completed and working properly. I need help right now, not requests for eye candy or tweaks.

I'm not much of a ROM designer or themer, so I just want to get CM9 out the door and be done with it. If you want to make a flashable zip for others to use on this ROM, that's fine by me.
[Galaxy S II General] wltklah:
With the latest nightly(0704), I found that my camera start to making strange vibration(sounds like auto focusing gone crazy). It happens when I came back to camera shooting mode from pic preview(in auto focusing mode). I didn't really take pictures for a week already, so this problem might already exist before 0704 version. I can confirm it wasn't the case before, because I took thousands of amazing shots with CM9 when I went to Alaska in May. I did wiped the 2 caches before I boot a newly flashed nightly.
[Galaxy S II General] TrainAss:
How often are you publishing builds? Are you taking a specific nightly build from the original ROM that this one is based on, and updating your ROM or are you working from your original ROM? And is the latest CWM that you posted mandatory or optional for this build?

I'm thinking of putting the latest build (back) on to my phone... ICS is just so much nicer than GB.

As for the pervious person's request for the Samsung Task Manager, if I grab the APKs for the requested files, how difficult is it to create an app pack (similar to Gapps) for the Samsung apps, that way anyone that wants to restore those apps can do so?

In extension of that, how difficult is it to make an app pack in general? I think it'd be a lot easier for me to restore a simple app pack if I wipe my phone, than re-downloading every.single.app.
[Galaxy S II General] markdexter:
If you guys download 7zip you can easily pull the apk you want and then install it on your cm9 ROM, however, dont even know if it will work anyway. If you have 7zip you will be amazed with how much you can do with ease! Maybe ill do a little video to show you, I'm no expert by any means, but its very easy!

give dsixda a break....
[Galaxy S II General] dsixda:
I'm only publishing builds now if I actually fix something. Then, if I can remember, ;) I'll do a 'repo sync' to get the latest general CM stuff. I'll check the Skyrocket and I717 builds once in a while but they are pretty much done anyway.

Latest CWM is optional unless you want to have more SD card issues. Of course a new version is an improvement, why have older ones that potentially have bugs?
[Galaxy S II General] TrainAss:
Makes sense!
[Galaxy S II General] B.Moreira:
I'll try to get the task manager from the stock rom if I can figure it out. I wasn't trying to put all the work on dsixda, I should have asked that as a general question instead.
[Galaxy S II General] dsixda:
Ok, I so i found the fix for the wrong CPU speed being read. It's in the kernel, you have to specify max/min frequencies and it was disabled. Starting a new build....

Probably due to this, Quadrant also crashes during the CPU test.
[Galaxy S II General] TrainAss:
I'll grab the Samsung APKs in the morning for you.
[Galaxy S II General] B.Moreira:
I tried putting the Tasks.apk and TasksProvider.apk in the CM9 rom that dsixda made but I'm not sure if thats all I need because it didn't work when I flashed it.
[Galaxy S II General] markdexter:
I think the .apk you need is the one i have added called jobmanager
[Galaxy S II General] dsixda:
On my Github page for device_samsung_celoxhd, I've posted instructions on how to build the ROM from source. If you're curious and want to hack around a bit, give it a shot.
[Galaxy S II General] B.Moreira:
I think the reason why the apps didn't work is because I just tried to flash the rom over top of the one I was running instead of doing a wipe. I'll try doing a full wipe and install tomorrow to see if it does the trick.

Thanks for the jobmanager apk, I probably would have never found out what the task manager was called. :P

[Galaxy S II General] dsixda:
Ok, I'm uploading the July 5 build. It should now have the correct CPU frequency of 1.5 GHz. However you still won't be able to overclock/underclock for now. On the other hand, Quadrant no longer crashes and you'll get a score like 3300, similar to the GS2 I9100.

Also, I have disabled the front camera so it does not appear in the camera app options.

I was having trouble with BLN so it's been disabled for now.

Crap, I forgot to include the instructions for the vendor files in the README.md file. Will upload that soon.

Go to my vendor repository files and open the vendor blobs mk file to see which files are responsible. I didn't modify anything.

Also doing a logcat will show you more info.
[Galaxy S II General] dsixda:
I'm assuming the problem with CM not playing certain videos may have to do with the fact it does not support certain formats/codecs that Samsung uses when recording with the stock firmware... Which is sometimes normal and can be resolved with a third party app like MX Player.
[Galaxy S II General] dsixda:
Ok it's up now.
[Galaxy S II General] markdexter:
seems fine so far!! One thing i have noticed is if you go to settings-advanced-sensors then turn off "enable keys backlight" when you uncheck it the touch keys go off, but then when you lock the phone and unlock it they pop back on.

it seems even changing the brightness breaks this too
