[Sony Xperia S, Acro S, Ion] dumbl3:
With cyanogenmod its better to do it like this yes. First boot.img, then ROM. Or at least in my experience it is. Either way it couldn't hurt..
[Sony Xperia S, Acro S, Ion] mirhl:
If you are still running stock kernel, then you'll definitely need to fastboot cm one

For the following times then it shouldn't be needed, given that every other kernel released in the last 5-6 months is just fine
[Sony Xperia S, Acro S, Ion] Ahmed:
So, for Cyanogenmod the answer is Yes. But what for other ROMS? For example Carbon Rom. I asked the same question in their thread and they said that I don't need to do that.
[Sony Xperia S, Acro S, Ion] cronot:
Well, I'd very much like to know where this "always flash kernel manually before flashing CM" came from. This confusion probably stems from the fact that, on the Xperia S, the recovery is built into the kernel. However, it all boils down to the recovery.

So, here's the deal: As [MENTION=4900593]mirhl[/MENTION] said above, if you're coming from a stock kernel / ROM, then yes, you will need to flash the CM kernel separately first - but that's only because such kernel will contain a recovery that can flash CM (and most other non-stock or non-stock-based ROMs) itself.

So, if you're updating or downgrading to a OpenSEMC (i.e. CM) build with another OpenSEMC build currently installed (or any other ROM based on CM or OpenSEMC, for that matter), you don't need to flash the kernel separately first - flashing the new kernel (boot.img) is part of the normal rom flashing process, so flashing the kernel manually first is a redundant step in this case - you will get the kernel that's currently on the zip either way if you just flash the zip.

The same goes when you're flashing from CM to Carbon, or PAC, or Omni, or whatever, or back the other way around - as long as the kernel you have currently flashed contains a recovery that's able to flash zip files without validating the manufacturer signature (which is really the main feature of any custom recovery, be it CWM, TWRP, etc.), you're fine, no need to flash the kernel manually first.

If you get bootloops or softbricks while flashing zips without flashing the kernel manually first, you most likely did something wrong. I never had to flash the kernel manually on my device except when going from a stock to a non-stock ROM.
[Sony Xperia S, Acro S, Ion] Ahmed:
I have a bootloader unlocked Xperia SL with the stock rom. It's not ROOTED yet. Can I flash this rom?

---------- Post added at 08:05 AM ---------- Previous post was at 08:01 AM ----------

In my friend's device (Live With Walkman), I wanted to go to Jelly Bean from Ice Cream Sandwitch. As I didn't flash the kernel manually first, it got stuck at boot logo. It worked when I flashed the kernel manually. But thank you, I clearly understand now.

Does anyone have a problem with internal speaker volume? How to increase volume in this ROM?
[Sony Xperia S, Acro S, Ion] hmzuleta:
Yes, you can. If it's your first time flashing on a Sony device, you can follow my tutorial (on my signature). Make sure you update us on how it goes.
[Sony Xperia S, Acro S, Ion] lammebn:
I have this problem, every time I power up or reboot my XS his lost the correct time, someone have the same problem?
[Sony Xperia S, Acro S, Ion] hmzuleta:
I used to. What I did is I changed the default CPU Governor in the Performance settings from Interactive to Ondemand, and checked the option that says "Set on boot".

There are some forum threads on other websites that mention other fixes.
[Sony Xperia S, Acro S, Ion] dangerzone:
short answer:

Reflash factory stock ROM to see if the problem gets fixed.

Reflash back to your favorite ROM

long answer:

My device exhibited this same behavior after a battery replacement (not recharging, not from running down to 0%)... the internal realtime clock (RTC) got reset to epoch time at every boot, and all my nandroid backup times were messed up and it was quite annoying.

I looked for ways to reset the RTC, some involving the terminal, but finally what worked for me was flashing back to stock ROM, setting the clock, rebooting a few times, and re-flashing back to CM-10.1.

By the way, this also fixed a camera manual-focus problem. It seems that the stock ROM initializes the hardware differently, and some settings can get "lost" when the battery is out.

[MENTION=612766]dangerzone[/MENTION]

even though your explanation was interesting I'd rather prefer one with less magic involved
[Sony Xperia S, Acro S, Ion] hmzuleta:
There are some things where one must try anything. Just begin with the allegedly simple solution then move on to the bizarre one. Everything is like that when troubleshooting any IT related topic. Lol.
[Sony Xperia S, Acro S, Ion] Ahmed:
Shouldn't this work on Xperia SL too? And if it works on SL, how can I overclock the CPU (you said you disabled OC). Note that Xperia SL has got 1.7 GHz, so if I flash this rom, I would probably get 1.5 Ghz max as it's the default for Xperia S
[Sony Xperia S, Acro S, Ion] cronot:
I can't assure you it'll work because I don't have an SL - but it *should* work, yes. And yes, with the kernel that's bundled with it, the clock will probably be capped at 1.5Ghz. I'm pretty sure the latest version of Kernel755 from [MENTION=4275152]someone755[/MENTION] for 4.2.x ROMs is compatible with OpenSEMC-U and contains the fix for the vol+ bug, so you can try that to squeeze the most out of your phone... http://xdaforums.com/showthread.php?t=2415636
[Sony Xperia S, Acro S, Ion] hmzuleta:
It does work on the XSL, I have it right now. It tops its CPU speeds at 1674MHz.
[Sony Xperia S, Acro S, Ion] Ahmed:
Thanks for making sure...
[Sony Xperia S, Acro S, Ion] someone755:
The newest Alpha on Kernel755 is basically the same thing as here, only OC'd and with some (ahem, broken) governors.

I thought we already ended this conversation...
[Sony Xperia S, Acro S, Ion] saumil007:
Does anyone still use the ROM ? If yes how's it ?
[Sony Xperia S, Acro S, Ion] hmzuleta:
Almost perfect, I would say. Everything works as expected. My brother's also using it and after 3 months he's getting some weird behavior with bluetooth, but I can't confirm this myself. Battery life is okay, in my opinion. It is longer in stock. I usually get around 8-9 hours of moderate use: 3G on all the time, 1h screen-on time, about 2 hours of music playback with Apollo or Walkman app, and some web browsing with Chrome.
[Sony Xperia S, Acro S, Ion] chanchari:
Do you think its performance is better than in Carbon ROM 4.4.4 using deedwar kernel 1.25?

Thanks
[Sony Xperia S, Acro S, Ion] hmzuleta:
I have never used it so I wouldn't know.
[Sony Xperia S, Acro S, Ion] Daniel_Lechu:
Thanks for this rom, better than 4.4.4 for now (all i've tested have a lot of bugs PA for example stuck after 2nd reboot, CM11 have random reboots...).

I've a little annoying problem: every time i reboot the phone, it says that is there's a new sim and i've to reboot (again) to make it work. I've discovered that is not necessary, but is annoying. How i can disable that message?

Greetings!!

Forget it!! ;) After 3 reboot pressing OK button, now i've ignored the message touching outside area and finally the msg is disabled...

[Sony Xperia S, Acro S, Ion] zaidx:
I wish lollipop was as stable as this ROM:(

[Sony Xperia S, Acro S, Ion] anantharam:
Should i install a seperate kernel for this ROM or should the stock 4.1.2 kernel do?
[Sony Xperia S, Acro S, Ion] mirhl:
....

Needed kernel is flashed alongside the rom..

No way stock one is going to work
[Sony Xperia S, Acro S, Ion] anantharam:
Can you tell me where i can find the kernal that i need to flash before flashing this rom?

I am coming from stock 4.1.2 ROM. It is rooted and has clockworkmod recovery installed, should i do anything else apart from just flashing this zip file?

[Sony Xperia S, Acro S, Ion] ChriMo:
I'm relativey new on Android. I do like slim independent and stable ROMs without Google and other stock bloat-ware. Therefore when I received a two year old SXS I first flashed Carbon and later crDroid which runs well on a Moto E. But sooner or later I always had forced system shutdowns. I then tried the OpenSEMC-U ROM from here because I read from some experienced user it is the most stable SXS Custom ROM. At first I taught a very good compromise of an older system (4.2), but slim and stable, but then the forced system shutdowns did begin also there. I did two complete new re-flashings over TWRP but it did not change.

I hope this is not caused by some of the apps I always install: mainly FOSS over F-Droid (DAVdroid, OSM~, Firefox, Adaway, etc.), at least in the runnings Apps window I only see the Keyboard when sometimes the system shuts down without further messages.

I would be happy to receive suggestions, maybe also to try another ROM (possibly without Google and Sony stuff).
[Sony Xperia S, Acro S, Ion] xDroidZz:
i only get force shutdown once in a while. (once a or twice a week). it isnt the apps i think since i also got a lot of apps in my phone with 4.2.2.

dont really know what your problem is. but my Open Semc-U 4.2.2 is the best rom that i used so far. best battery management. stable and fluid. :good:
[Sony Xperia S, Acro S, Ion] ChriMo:
[MENTION=4884137]xDroidZz[/MENTION] thanks for your feedback confirming Open Semc-U 4.2.2 should be the best Custom ROM. I'm not sure what to do since this ROM seems to be not anymore actively developed. Maybe I will try Stock ROM for some time to see if Forced Shutdown is occurring there also (Hardware issue?).
[Sony Xperia S, Acro S, Ion] A6ekAK:
Just stay on "clean" system for some time and see if it's crashing or not. No chances it's hardware problem... But remember to make a full stock flash using flashtool.
[Sony Xperia S, Acro S, Ion] xDroidZz:
its your phone, its your choice. :) :good: of course this rom isnt active anymore. they all started working on 4.4 and Lolipop :D even 4.3 got stopped after release of KK.
[Sony Xperia S, Acro S, Ion] ChriMo:
Could be that with the 2nd stock flashing I made to overcome softbrick/boot-freeze something went wrong. If have the log - will see, I think I have to try a second time. That seems a plausible reason since before SXS was running decently stable on crDroid (FCs, but no system shutdown) for a week or so. Thx.

EDIT: clean Open Semc-U 4.2.2 is now running since 16 hours and that is a good sign. Will now install/setup a contact/calendar app (DAVdroid) to make the phone more usable. I hope I do not need to reflash Stock and do the whole CustomROM process again.

Could be "hot inserting" the SIM card a problem? I mean inserting the SIM while the system is up? On Moto E this is no problem, but it could be that in the previous Open Semc installation which had forced shutdowns I did that (not on the currently running one).

[Sony Xperia S, Acro S, Ion] ChriMo:
Hmm, is AOSP Kk really more stable then OpenSEMC-U? I also like the CM adds as base optimization, so not sure if I should give one of them a try. So far I had no more forced shutdowns on the current OpenSEMC system. Do have an opinion on this [MENTION=4884137]xDroidZz[/MENTION] ?

Both camera and screenshot are working fine with xposed.

are you sure, the problem's are bcoz of xposed?
[Sony Xperia S, Acro S, Ion] _Vegas:
sure, disabled all the modules,and wiped dalvik cache.

Only uninstall the xposed framework in xposed app and wipe the dalvik cache, then the camera works.(xposed 2.7.1) maybe 2.6 should be fine ?

Edit

Tried , doesn't work.
[Sony Xperia S, Acro S, Ion] ChriMo:
Regarding stability of my SXS with OpenSEMC-U: so far running well. I'm installing only one app every 6-12 hours to see if one of them caused the earlier problem. But could also that it was a flashing issue. Battery lifetime seems much better then with any other ROM I tested (Kk Carbon, crDroid) so far.
[Sony Xperia S, Acro S, Ion] mpulock:
Strange, My camera works just fine. Although, I use only Gravitybox module. My Xposed app screen flckers when moving from page to page, sometimes I can't search or download, the list doesn't show up. But, i don't get any troubles from other apps because of it.

Anyway, hey, Do you use the 'GPSNotification' module? I googled this link, where this guy was having kind of same of your problem:

http://forum.cyanogenmod.org/topic/96584-xposed-framework-module-causing-camera-to-crash-system-ui/

Let me know, If you tried any other camera apps , and the result is same.
[Sony Xperia S, Acro S, Ion] _Vegas:
No, haven't use it, and I have disabled all the modules in xposed app.

Any other camera apps doesn't work too.

When I open the camera, I can see the ui, then it says:can't connect to camera

First of all, thank you very much for your work and for fixing the remaining bugs! :good:

Sorry for a noobish question but can we just replace the blob files in the phone with the ones from this zip? That way we can switch between the old blobs and the new ones whenever we want. Or do we necessarily have to flash the zip? If yes, could you please make another zip with the new blobs, so we can flash any of the two when we need?

Thanks again! :)

I searched about that and it seems 4.2 broke out this AVRCP feature. According to this 4.2.2 ROM with Bluetooth AVRCP/MAP Support. slimbean seems to fix this and we had an official build for this rom so you may ask them to know how they did this.

Hey, I've been using this rom for a couple of days, I flash custom roms every 2 months or so to see how stable they are and if I can settle with on of them for my daily driver, I gotta say that this one is the closest I've been.

[Sony Xperia S, Acro S, Ion] mirhl:
if your operator has FD enabled and you are sure you aren't experiencing fast-dormancy related wakelocks, then it would be better to stick with the default fd policy

if you don't meet these requirements however you had better disable FD, cause it would harm your battery life

btw if you want to reenable it, just replace your MMC and MCC code with the original 0

You're amazing!!

And thanks for giving us the option for the camera. If I want to record 1080p; I'll get ny dSLR. I'm going to flash the .211 cam.

Edit:

BTW... Why is there an old OS mentioned in the build.prop?
[Sony Xperia S, Acro S, Ion] AnrgKrshn:
I can't believe no one's mentioned this. ROM is flying even though under clocked to 1.2 and conservative governor

And also, delayed wake seems to be fixed :D
[Sony Xperia S, Acro S, Ion] revan17:
The purple tint is there while taking flash photos(all pics have a purplish feel). It can be solved by setting the white balance to manual(fluorescent). It was a bug in .211 firmware, solved in .96. And yes, it's present here also with .211 blobs.
[Sony Xperia S, Acro S, Ion] cronot:
First, some news.

I've been playing with the blobs, and found out that mixing the newer liboemcamera.so blob with the older libcald_pal.so blob allows for fast camera startup WITH smooth 1080P video. :) I've added CameraMixedBlobs.zip to the downloads section - please flash it and give me some feedback on this.

Now, on to some Q&A:

Done, check the downloads section - along with the zip mentioned above, I've uploaded CameraNewBlobs.zip too, just in case.

That's how it is on RaymanFX's builds too (at least as far as RC2). I wouldn't be surprised if the FXP ROMs are the same. IIRC, these properties are mainly used by the Play Store to identify your device and tailor the apps selection to it. I'll see how it's set on Sony's latest release and tweak it if necessary, but I wouldn't worry about it, it's hardly going to make any difference.

Please try flashing CameraMixOem.zip mentioned above, and let me know if it helps - it's really hard for me to test this since it's only noticeable under specific lighting conditions (apparently, using flash on dark environments), and I'm in a well lit environment for most of the day.
[Sony Xperia S, Acro S, Ion] revan17:
Will do instantly. Perhaps you forgot to post the new zip? :P

Sorry, am an idiot. :)

---------- Post added at 03:31 PM ---------- Previous post was at 03:18 PM ----------

Nope, same issue with regards to the purple tint. Thanks for trying though.
[Sony Xperia S, Acro S, Ion] Redstarr1:
Awesome, it's been ages since I could record in Full HD, never bothered to use the stock .96 update. Not that I'm going to use it, takes up too much space and is a bit big to upload, but still nice to have a little more of the original functionality.

You can reduce the purple tint by using a different white balance setting, not automatic. But you probably already know about that. The grey sheet I'm trying to photograph still looks a little purple though. Pics in the dark with the flash never were really good anyway.
[Sony Xperia S, Acro S, Ion] ville525:
The CameraMixedBlobs.zip works great for me, the camera launches instantly and 1080p is smooth! :)
[Sony Xperia S, Acro S, Ion] Redstarr1:

OpenSEMC makes me feel my phone really does have 1GB of RAM. :good:
[Sony Xperia S, Acro S, Ion] Phat7:
It's really great that we have dedicated members who fix remaining bugs, so thanks to the OP for that!

Having said that, I tried the ROM and found that the battery drain is bigger than Rayman's RC2, so had to go back to his. I also confirmed that this is not related to the fast dormancy issue. Most likely this is to do with the new kernel.

Could I please request that you apply the volume up bug fix to Rayman's RC2 kernel and share that, so we have the option to use that kernel as well? So the ideal option would be to have this ROM with Hangouts bug fix + Rayman's RC2 kernel with volume up bug fix + Camera Mixed Blobs. I would be so happy :fingers-crossed: I think all other users would be as well!

If you don't mind me asking, what is the best method/app to change voltage and clock speeds?
[Sony Xperia S, Acro S, Ion] revan17:
Personally have no need for doing that. I charge my phone every night. :P But thanks for the tips.
[Sony Xperia S, Acro S, Ion] AnrgKrshn:
Should I under volt all frequencies?I'm new to this :)
[Sony Xperia S, Acro S, Ion] AnrgKrshn:
I'm sorry, but I didn't get you. I should under volt every frequency by 50? Even 192?
[Sony Xperia S, Acro S, Ion] Redstarr1:
Well you say there is more battery drain, but you don't give an example. How long did you try the ROM? Every ROM needs some time to settle since there's a lot of syncing the first day. So of course the drain will be bigger. And I think it's highly unlikely to be the kernel since it's very close to the RC2 kernel. Did you try a different governor? Not all of them are very good, if you say RC2 kernel is better, set the governor to ondemand and try that for a while.

No everything minus 50 except the ones that are already close to 800, 800 is minimum. I went below that though, not right now on OpenSEMC but with DoomKernel it was possible to go to 775 or something (if I recall correctly).
[Sony Xperia S, Acro S, Ion] AnrgKrshn:
I totally messed up, can anyone give me the stock voltages for this kernel or their own settings? I brought everything down to 800 mv
[Sony Xperia S, Acro S, Ion] revan17:
Just clear Kernel Tuner data, uninstall, re-install. It should be back to stock. If not reboot and you're good.
