Hi. Is there a stable solution for the BSODs (Black screen of deaths) problem?!? It happens with cm7 and miui roms (AOSP roms). Is it related to the kernel, to the baseband or what else? If you have suggestions...please share with us!!!
For problems with certain rom/kernel, it would be better to search for answer in their certain thread, as you haven`t write which is your rom/kernel. I would try with changing kernel first or try to over-volt current kernel to see if helps.
However, I would recommend you to go to cutom stock based roms/kernels, which are good, fast and stable. Put an eye on this one .
Or to be sure that it is not a hardware error, go back to pure stock first.
According to temasek their's a way to reduce it but not totally vanish this problem the source of this problem is unknown until today according to him
Ok im getting a used phone that is stocked never been rooted and ill update to 2.3.5. What is best stable rom with battery life and OC after i odin and corn kk_4 v705 and do i need BL drs or not necessary?
Many ROMs are stable. Best ROM is the one you like most.
For people with no experience with Captivate I always recommend this Guide. It shows step-by-step how to update the OS from GB to CM10.x stable. CyanogenMod is the most popular ROM, CM10.1.3 Stable is JB 4.2.2 based, CM10.2 Stable is JB 4.3.1 based. Don't flash beta or experimental ROMs as your first custom ROM. Read the guide VERY carefully and try to understand what you are doing.
Ive had Cappy back in the day with Heimdall days and 2.2 lol. Im getting a used Cappy this week it will be 2.1. Yes i already have latest stable 10 and gapps downloaded and ready and wanted to know if i can use the s3 touch wiz after all is said and done? Sec launcher signed or unsigned? Can i use neat kernel on this or what do you recommend for OC`ing?
- You can't upgrade to CM10.x starting from Eclair, read the Guide.
- You can get TouchWiz style theme and/or TouchWiz launcher, whatever you like.
- Be careful what kernel/version you are looking at, different kernels are for different Android versions.
- I wouldn't recommend OC over 1.2GHz. Default CM kernel supports step OC to 1.2GHz.
- Careful with CM10.2 Android 4.3.1 based, kernel change may break the ROM.
I see you are in a hurry to transform your Captivate to something awesome, but please read more and understand what you are doing. All the information needed is already here on XDA. Use Search and you'll fund what you are looking for. Upgrading from 2.1 to 2.3.x includes bootloaders flash and a risk to brick your device. I recommend you to use KIES for this process, follow the instructions closely.
I meant after ive done the kies and 2.3.5
OK
- you can use whatever you want launcher with CM10.x
- Neat kernel is for different Android version (4.4.x), don't flash it
- for CM10.2 my recommendation is to use default CM kernel
hello, mine is CM10.1.3 but I was able to use the JB 4.3 but its running real slow. do I need to update it for something?

CM11 Android 4.4.2 based nightly builds are quite stable. Some features are still missing, but coming back soon. I'm currently running latest 20131215 and I have no issues whatsoever. In my opinion, CM11 runs better than CM10.2 and uses less RAM. Leave ART alone for now, it's in experimental stage and more potent hardware is needed to show real advantages; use default Dalvik VM.
Keep in mind, that once the phone is repartitioned to run CM10.2/CM11 there is no easy way to go back to CM10.1. You'll need to go back to stock GB, flash Corn kernel, flash CM10.1 to repartition, flash CM10.1 again to install the ROM.
thank you! but can I directly update it to CM11? since Im running CM 10.1 or do I first need to update it to CM10.2?

once you get a custom recovery on the phone, then it becomes a much easier process. I only really found trying to unlock the phone as the main difficult item.
Hi,
I installed 2 weeks ago the latest Beanstalk 4.4.4010 CM-based and I really liked it, it is a very nice ROM and increased the life and performance of my phone by a lot.
At the beginning everything was fine, but now after 2 weeks I am having again the same network problems (losing connectivity, not being able to recover signal, and so on) that I had with my old CM ROM.
After reading a bit around in the forum, I found that there is this RIL change solution http://forum.xda-developers.com/showthread.php?t=2496075
But since this is a bit older, I don't know if it has been already implemented or not in the recent Beanstalk updates or if I still have to do it. And also if this only works with the P880-dev based ROMs or also with the CM based ones. It is difficult to say when one has to read so many threads.
Also an user uploaded a flashable zip fix of the RIL for the AD version. Does this mean that I can flash the P880-dev based ROM with AD and then just flash this zip and would avoid having to do the procedure of the above tutorial?
Is there another flashable alternative for me?
I also read somewhere that NamelessRom wasn't having this issue, so do you recommend to switch?
Thanks,
SC.
there are still several versions of RIL; i recommend you try a few of them till you find out the one that works.
the zip that was made for the AD version of rom works only and only with that specific rom, made on that specific date. any rom that was built after (or before) needs to have different flashable zip.
i do recommend you try nameless rom first (take a backup of beanstalk). take it for a spin for a few hours/days and see if you have any network issues. if you do not, you can extract RIL from nameless rom & implement it in beanstalk. good luck

As thick said, most custom kernels do come with double tap to wake, aka dt2w.
I'm assuming you know the procedure for rooting and flashing a ROM.
In order to get dt2w, first flash a ROM of choice. Boot up, and set it up according to your liking. Then, find a compatible kernel (we can help you with that), and flash that. Boot up again, make sure (in your phone's settings) that the kernel flashed successfully, then download a kernel tuning app like TricksterMOD and go into "Screen Wake Settings."
Note: some kernels may use AROMA, which lets you configure dt2w while flashing. The above should still apply if you want to change your settings later on.
Thick's ROM comes with it built in, but most other ROMs don't.
Happy flashing, and remember, ask twice, flash once.
I appreciate it!!
I rooted and played around with different Roms on my previous phones e.g. HTC Hero, NS4g, and Evo4G
but since my HTC one is still being updated via OTA officially I didn't proceed with rooting yet.
I really wanted DT2w feature and I don't think any update would give me that feature so that's why
I am thinking about rooting my phone. I really appreciate your help since you said you can help with
choosing a kernel please go ahead and suggest a good kernel and few feature rich/stable Roms.

I would suggest SD 12 since it's on the latest base (.12, which has some important bug fixes) and it's relatively close to stock.
Along with that, I would suggest using ElementalX 18, which is one of the more easy Kernels to set up. It uses AROMA, so you don't have to download any apps to adjust your settings later. I had a good experience with the battery saving/thermal throttling/undervolting settings (you'll see those come up when you try to flash it). I don't recommend messing with the clock settings, however.
Wipe (default wipe in TWRP), flash ROM, boot, set up, go into recovery, flash kernel, reboot, wait, reboot again. That's the procedure I follow.

EX 18 is a 4.4.3 kernel, you probably used it on a 4.4.2 ROM. A 25 mV undervolt with "run cool" setting would be good.

Yes you are right I was trying it first on my stock rom which was 4.4.2 if I am not mistaken that was the last official OTA
update for me. I am on SD 12 ROM and EX18 Kernel at the moment and loving it. I tried SlimKat which was not bad but for some reason I couldn't fix the resolution of the screen everything was too small for me (icons,fonts etc). Latest Liquid Smooth didnt recognize my sim card so I had to move away from it. It seems like for now SD12 is going to be my daily driver.
In case if I want to give SlimKat another shot can I use EX18 on it or it's only a sense kernel? also SlimKat is 4.4.4 so what good kernel can you suggest which will give me DT2W option?

Hi,
since the official maintainer "solk2" for the GT-I9506 moved on to CM12 before providing a final build incorporating his latest fixes I decided to make my own builds.
According to my personal experience the battery life has vastly improved. In particular the power consumption while the display is off has decreased substantially. Solk2 has apparently fixed some issues with the kernel so the battery issues are gone. So for everyone not yet willing to transition to CM12 (in my case inter alia due to the currently unstable state and the lack of a stable Xposed framework in Android 5) this might be a good alternative.
I will gladly share my unofficial ROMs, however I would need someone to host the files in order to do that. If anyone would be so kind as to host ROMs please let me know.
If any relevant code changes to CM11 will appear I will most certainly compile a new version.
* IMPORTANT *
Please note that these builds are based on nothing else than the unchanged official code from Cyanogenmod, solk2 and others. So every credit goes to them.
I will not and cannot make any changes to the code. The only thing I can do and will do is build a ROM thereof in case some interesting fixes etc. appear. However, since CM11 is becoming outdated there will most probably not be a lot of changes to come.
Also, it should be understood that I take no responsibilities whatsoever if anything goes wrong when you install the ROM. Like the original ROM this is completely at your own risk!
However, you can expect that any ROM I share has been installed on my own GT-I9506 (with Samsung firmware of 4.4.2 nordic countries) and runs without obvious issues. Your mileage may vary.
Here is the current version, including the CM-11.0 code base up to http://review.cyanogenmod.org/#/c/97688/ :
https://www.mediafire.com/folder/j0jynk3en95j5n1,soag9jcmrcajdhq/shared
* Note *
At least some of the issues with solk2's latest official builds were apparently caused by preceding changes to the kernel code. My builds use the latest code base of February 16 incorporating solk2's latest fixes (see https://github.com/CyanogenMod/android_kernel_samsung_ks01lte/commits/cm-11.0).
Unless solk2 will make further changes to the kernel (which I doubt as he has turned his attention to CM-12) the changes in my builds are only related to merged changes in the official Cyanogenmod code for CM-11.0 (see http://review.cyanogenmod.org/#/q/status:merged+branch:+cm-11.0). In other words the kernel will remain the same, even if the build date thereof may change.
Thank You. Perfect rom. in 2015-05-20 mms is working by default I have not find any bugs.
I'm on arter97 CM12.1 and I'd like to try this one. I can imagine a such install procedure:
-flash kk stock firmware (CNJ1 nordic) from odin
-reboot
-flash custom recovery from odin
-reboot
-flash your rom from custom recovery
Is that right?

You do not need flash any stock. Just flash TWRP, make full wipe and flash this rom + gapps
Why is this rom so ignored? I flashed it a few days ago and I find it's great. Very very fast and absolutely rock solid. No bugs, no fc, no reboots.

I do not know how many have installed this ROM (anyone having done so please leave a reply here).
I see only a very limited number of reasons to transition to a new version of a ROM or Android in general:
1. If the new version provides functionality that I want or need (and material design isn't one of those); or
2. If the new version fixes a bug or security flaw (there is none that I know of).
At the moment CM-12 does not fulfill any of these criteria, instead I would lose the solidly working Xposed framework for an alpha version thereof.
I'm not intending to advertise this ROM, inter alia because the only thing I did was build it, so the credits should still go to solk2. But if anyone hears that someone has issues with the latest "official" version of CM-11, please direct them here.

Do you have some knowledge on building stuff ? (via linux command, problem etc)
What should happen if I update via OTA as it ask me to do?
edit: I realized that the updates suggested are cm12 so can be ignored
I had one strange bug in this rom (maybe reason was in gapps): Go to SMS app, push new and write name in address line from above: phone getting list of contacts to chise. You choisew one and see wrong number (without region code) in address line.
If you push on contacts button and choise contacts here everything will be ok.

Then maybe you should ask Arter97 what's different in his kernel... Without any hint what difference causes this no-one has a realistic chance to find out. Or ask him to adapt his kernel to CM-based ROMs. I didn't know that his kernel does not work with CM, is that so?
Also, on my S4 I do not have frequent reboots. However, I once activate the advanced option "kernel samepage merging" and then had two reboots in 1-2 days. After resetting to deactivated no more reboots since about 2 weeks... Worth a try to check.
I would like to help, but I simply do not have anywhere near the experience and knowledge to find a kernel bug that apparently solk has not found himself!

Well, another problem... I'm not sure if it is a bug in settings.apk or only in connection with our device. However, when you check the option is always ON, and upon leaving the settings.apk it will always return to being ON. So at least I can say that turning if OFF cannot have had an effect because it was never turned OFF.
However, I will try with KSM disabled now. For the time being you can manually disable it and lock this state (well at least until next reboot) by doing the following in an adb session or the terminal:
echo 0 > /sys/kernel/mm/ksm/run
chmod 444 /sys/kernel/mm/ksm/run
Another way would be to recompile the kernel with the option disabled. It would be far better to fix the issue in settings.apk. However, to file a bug report one would have to check if the behaviour is the same in the official nightlies... I read that someone reported this as a bug for the Oneplus One, but it was never resolved.
As an somewhat veteran in other xda-like forums, I advertised link to neudlis reply with his/her first build because it has been rock stable and fast. With my I9506 nordic.
No other customs have been this solid for 3 weeks straight, and I have been trying roms since december !

Although I cannot often enough remind everyone that I did not provide or change any code but just build it that's still not too bad for the first build of a guy not that much into coding .
After a weekend with not much use but some hours of listening to audio books I was left with 21% charge after more than 3 days (see attached screenshot). That's just awesome! So I believe it can safely be said that any power consumption bug was resolved by solk2's latest patches to the kernel.
Also I believe that turning off kernel samepage merging might have helped additionally, so I encourage everyone to try it as well (see above post for manual way to turn it off as bug in settings.apk won't let you otherwise). In my opinion this option should default to off as it is said to be potentially unstable and the I9506 surely has enough RAM not to need it. So I prefer to lessen CPU load for longer battery life in exchange for potentially increased RAM occupation.
