Hey guys! this is Marco from Costa Rica, I´ve been around for a while but just created an account so I could ask something to what I haven't found an answer:
Is there any way to enable Swap support on stock JB for Galaxy S2? maybe through XPosed?
Or if not, do you know what's the closest ROM to stock that supports this, I know it might be a little naive, but I'd like to keep it as close to stock as possible.
Thanks and as we say here Pura Vida!
If your kernel supports swap you could look at this http://forum.xda-developers.com/showthread.php?t=2460068.
Alternatively you could use an app for such purposes.
To check if your kernel supports swap use this https://play.google.com/store/apps/details?id=com.roehsoft.meminfo

that's the thing, I know my kernel doesn't support it I already checked with that app before, I actually want to use Roehsoft ram ezpander swap. But I really don´t know what kernel or rom to install so it works without loosing stock features that sometimes are taken out in roms
For the I9100G, this kernelhttp://forum.xda-developers.com/galaxy-s2/development/kernel-blazing-kernel-v16-t2275275 works with stock rom and has swap support.
For the I9100 I don't know. Though I would assume most custom kernels support it. (or maybe not)
Also I can't really tell what you mean by "stock features".

Hello
I'm new to this...
I was wondering if I can install the SpeedMod Kernel on my SGS2??
Why this Question:
When I rooted my decive with cf-root and odin I have chosen the Kernel with the same "version" my stock kernel had.
Now I'm not sure if I can install any sgs2 kernel (in this case SpeedMod) or if the "version" is important.
I think that all SGS2 Phones should have the same hardware so I sould be able to use any Kernel. Is that right?
What do I have to be aware of, when I choose a new kernel?
Thanks
Ditschi
Yes you can, don't worry about it. Versions don't care much after all.
Thanks a lot thought that. I'll flash he kernel tomorow.
But what im interested in:
When you say the version doesn't matter why are there so many versions of cf-root? Is'nt that a lot of extra work? Why not useing only one kernel?
Cheers
Ditschi
That's for people who want to stay as close as possible to stock.
The developers compile their kernel to work with any Samsung or TouchWiz based rom.
CF Root extracts the kernels from the specific rom, adds in the goodies and presents it to us for use to root the respective rom. So basically what you have is the stock kernel with root added among other things
ah ok...
That makes sense. Thanks a Lot for the help
I need to fix a friend's phone, could you suggest me wich rom and kernel to use? I have no idea.
Also is there any hope that this phone will see android 4 with cyanogen? Will the gpu support it'
I plan to use this guide I made time ago

Edit I think I found some nice suggestions in this thread about custom roms
http://forum.xda-developers.com/showthread.php?t=1366300
Hey all, I've recently rooted, unlocked, and installed a AOKP rom on my I777, and the rom has some really cool features for a custom kernel (overclocking, fast charge, etc.) I have been poking around google and the forum to find a good kernel to install for my phone, and I'm new enough at android hacking that I dont want to risk ruining my phone by installing the wrong one.
So my question is, what is a good stable kernel that works for the I777 that supports as many tweaks and goodies as my phone can handle?
also, if my rom says it supports a feature like fast charge or what have you, that doesn't necessarily mean my phone itself will be able to use it, correct?
Thanks in advanced!
Hi,
I am a new Galaxy S II (i9100) owner. I have a couple of questions, if some of the experienced users could please assist me I would greatly appreciate it. My questions are listed by priority:
EDIT: I am rephrasing my questions and putting the answers that I feel are best suited so that people who are interested can see the answers in one clean post
1) I understand that CM Mod is based on AOSP and is used as a base on a lot of ROMS but could someone please explain to me how a ROM could be an AOKP ROM and "Based on CM10". Are they taking certain modules from CM10 and certain things from an AOKP Build and putting it together?
ROMS usually take the best of CM and AOKP and combine to produce a more stable base.
2) I know what CWM is but once you use ODIN to flash CWM onto your phone where does it go? By this I mean, does it sit on the ROM or somewhere on your Internal SD card (or both, maybe it puts settings on your SD card). I would like to know if I format my Internal memory will it remove or cause CWM to bug out?
CWM will get removed from your phone if you flash a Kernal that doesn't have CWM on it. It will also get removed from your phone if you "format" the internal SD as that is where it is stored. CWM will NOT be removed if you flash a update to your phone that doesn't require you to "wipe"
3) I am not a fan of the Stock Samsung ROMS because of the bloatware that it contains. However, is it all possible that these Stock Samsung ROMS have built in optimization code or something that works better for my specific device? I ask this because the best battery life I've managed to get was on Stock Samsung ICS where as my battery life dies on any of the JB Roms (Even SlimBean)
AFAIK Stock Roms are optimized for basic / standard features. Custom ROM's can be optimized for the way you use your phone. A Stock ROM is a "One Size Fits all ROM" a Custom ROM can be "Tailored" to fit your needs.
4) I understand how I/O Schedulers / Governors etc work but what advantage does using a non stock Kernel have? As far as I understand these can be changed on any rooted Kernel or am I incorrect?
I/O Schedulers / Governors can be changed on rooted or non rooted Kernels. Rooted Kernels have access to their own custom schedulers and governors.
5) When I download an app from Play store is there no way for me to not install it and just download the APK? So that I don't have to backup all my apps (I don't like using Titanium very much) and so that I can just reinstall the APK files from my internal Memory?
No There is no way to get around this. Install APK files from the Web. Use Titanium Backup to backup applications installed from the Play Store.
6) I've followed the guide to enable or disable Fast Dormancy (I'm still learning about this) however when I type the code in my phone (*#9900#) or (*#0011#) nothing happens. Is this because I'm running JB and these codes only work on ICS?
These codes only work on Stock ROMS
7) When I have a look at my battery usage (currently on CM10) screen says "52%" even though my brightness is set to like 25%. I am trying to figure out why my battery is dying so fast. Is this normal?
There is no "Normal". Too many factors involved. Have a look at the BBS Thread http://forum.xda-developers.com/show....php?t=1179809. You may post your BBS dump/log in this thread and ask the experts to analyze it for you.
8) What is the main difference between AOSP and AOKP? I understand that AOKP will open up a lot of other customizations to me but what are these customizations? I assumed it was things like setting the governor and the I/O Scheduler etc but I've installed ROMS based on AOSP that allows me to do that.
Busy Formulating an answer
9) Galaxy S2 Modems I keep flashing different modems on my phone but I see no change in signal whatsoever is there an application or anything that can help me get an accurate benchmark so that I know which modem is "best" for me?
This is usually done by trial and error. Have a look at the Modem / RILS thread to ensure that your Baseband and RIL version match. Alternatively you can use an app called GETRIL which will get the correct RIL file for your modem
10) Please don't mistake this as a "What's the best ROM??" question. I've tried many different ROMs and I still haven't got a favorite I am looking for someone who has an idea of which ROM will mostly fulfill my requirements which are:
(BTW I'm leaning towards SlimBean here)
1) JB (I love JB keyboard)
2) Battery life (I think I'm looking for something that uses the conservative governor)
3) I mainly use my phone for WhatsApp (I use this ALOT) and browsing (barely for games)
4) Lightweight (I don't want Samsung Apps, I don't want a ROM that has 3 launchers etc.)
5) I don't mind charging my phone once every 16-18 hours.
6) Preferably AOKP so I can mess around and experiment and perhaps give back to the community
This is my personal opinion but I think that SlimBean will best fit my requirements

Ha ha, next time, please don't post so many questions in one post.
Then you will get more answers IMO.
I can't answer every question, but I'll try my best:
1) As I am using stock / Sammy ROMs only, I can give no clue to that. Please search and read a bit in ROM threads.
2) In SGS2 firmware, recovery (CWM is a special, enhanced recovery) is included in the kernel. If you format your internal memory (sd card), it will be removed, and will have to flash a new firmware (whole ROM including a new kernel with recovery) to your phone.
3) I like stock / Sammy ROMs, but custom ROMs may include same or similar device-specific drivers/etc. AFAIK.
4) Most custom kernels support different I/O Schedulers and CPU Governors. So you can switch to the one you like/prefer.
5) Apps from Play store will be automatically installed on your phone. That's why so many users are using Titanium Backup.
6) There is an app from gokhanmoral to switch Fast Dormancy on/off. I don't have the link, so you have to search for it here on xda. The USSD codes won't work on some ROMsm such as non-stock or JB.
7) Have a look at BBS thread => http://forum.xda-developers.com/showthread.php?t=1179809. You may post your BBS dump/log in this thread and ask the experts to analyze it for you.
8) Have already google it, or look at wikipeadia. I have no better answer ... sorry.
9) Have a look at the modem thread here => http://forum.xda-developers.com/showthread.php?t=1131950, and here for modem/RIL files => http://forum.xda-developers.com/showthread.php?t=1881304
10) No "What's the best ROM??" question?! Sounds like that to me You have to check different ROMs yourself and decide yourself what's best for you and your needs.
Good luck !

1. Yes the best of cm and AOKP where combined to produce a more stable base.
2. CWM or clockworkmode is a phone based recovery that allows you to make changes without powering and rebooting the phone in recovery mode. It is added to rooted kernel and will disappear if you flash a wiped or standard kernal over it.
It will not disappear if you flash an non wipe update to your phone.
3. jb roms are getting better with the battery as new optimizations are being intergrated. Stock roms were designed around the battery with minimal features implemented, when you add apps your battery will start get worse.
4. yes they can be changed on rooted kernals or non rooted kernals. On rooted kernals it gives you more control over the functions of the phone.
5. unfortnately play store automatically installs the apks automatically. you need to back them up with a program similiar to titanium back up. They are a few different versions in play store just find one you like. Only non play store apps download the apk for you to install yourself. One of the functions of CWM is to allow you to install APKS. I System Tuner Pro myself.
6. Correct, those codes only work with the stock keyboard and ics roms as JB Have very little stock apps included.
7. How fast the batttery discharges depends on a number of factors like what apps are running, If you leave wi fi on and if you have wake locks. BBs which is a battery recording app can found on this forum. Make a log of a day and post it and experenced members will review it and advise what to do to get better battery life.
8. You need to ask a developer what the differences are. But I think AOKP is an upgrade of AOSP.
9. No trial and error is the only method. Your baseband and ril must match to get the most efficiency
out of your modem. There is a small program called GETRIL which will update the ril for you.
10. unfortunately everybody's preferences are different so it is another case of trying roms till you find on you are happy with.
I hope that these answers of some help.
@It_ler @Cosmic Blue
Thanks for the replies... I have a better understanding already. I've read up on GETRIL and will give that a try.
2) In SGS2 firmware, recovery (CWM is a special, enhanced recovery) is included in the kernel. If you format your internal memory (sd card), it will be removed, and will have to flash a new firmware (whole ROM including a new kernel with recovery) to your phone.

I understand. But is the internal memory partitioned? If I use X-plore I have a 11gig SD Memory and then I have a "/Root" folder which is 2gigs
Structure looks like this: /sdcard 11gb (10.9gbfree)
/root 2gb (1.7gb free)
Does CWM and Kernel not sit in /root? and is "/root" not a separate partition?
So...Instead of doing your own research & getting full/accurate answers to your questions (and learning a lot in the process), you'd rather sit here & wait for 'users' to give you mostly vague-ish answers to them ?
(Hint: By & large, developers do not read Q&A. They have better things to do.)

MistahBungle this is a Q&A thread if you don't have any A's then rather don't post. I've had the Galaxy for 3 days. In 3 days I've read a lot and done a lot of research. You reply makes no sense that's like saying: "So Instead of failing many times and then getting it right you'd rather Google and get it right the first time?". I posted here because I know 90% of the people here are experts and will give me the answers I'm looking for. Also, I'm not posting questions like "OMG Lulz teach me how to root my phone" you can see that I've tried and these are questions that I have after trying out different ROMS.
Thanks to those that are willing to help, this is what builds a good community.
So that link I posted is an illusion, huh ?

Before you start getting hostile please realise nobody on this site is obliged to help you and anyone who does reply to your thread does so in their own time and off their own volition. Beggers can't be choosers.
But otherwise your post isn't too bad. The differences between CM and AOKP are mainly cosmetic and to do with feature. There is no "AOSP" as everything is at its core based off AOSP. I always image AOKP as just a more streamlined, feature inclusive CM but recently they have started to add their own tweaks etc. Honestly, it doesn't matter anymore because with Siyah kernel (and kernels like it) being able to work on multiple platforms you can have ROMs with CM base and AOKP+Paranoid features.
The "features" I'm talking about are stuff like integrated weather, quick flashlight toggle, change the battery/signal display, etc etc.

I do agree that I should've responded in a better way, and that people are not obliged to help me. That's why I thank the people that do help. However, commenting on a thread and telling the OP to do his research doesn't seem constructive to me whatsoever (I've seen many threads like this). Posting a link is a quick CTRL+V and is way more constructive IMO.
Thanks for clearing up the differences for me. It makes a lot of sense. Everything is based on AOSP since that is the most "pure" release. AOKP is modified AOSP and CM is also Modified AOSP. So essentially most AOKP Roms take the best from AOKP builds and CM builds.
Hi ,
I've got couple questions to this rom but i can't write in direct topic yet, if wrong forum than change me
1. Please tell is it possible to set 5 icons in menu like s5? i don't want to set any luncher. For now i've got installed Wanam.
2. Second question do you have in your s3 little luggy/stutter while moving screen? Is it possible to improve it? Ofc with out changing rom
3. To users of this rom. Which kernel do you use and what is advantages? Is it a lot different between kernels?
4. ... I forgot this one

1. Yes, look at the screenshots in the dev thread
2. If it isn't smooth enough for you, install a custom kernel like Boeffla and try different governors to find the best suited for your expected smoothness/battery saving expectations. Try also not to have to much apps running at the same time, try Greenify it's great.
3. All popular kernels are great, and the settings you choose can change a lot the performance and battery saving of your phone.
Thank you for your response
1. Yes i know, that's the question how to do it? Because I've got 4x5 i my rom.
2. Can i flash it without rom, just kernel? (+ wipe dalvic?)
I've instelled UPSM manager, but i don't see any changes? Greenify is better and is it the same app?
3. I should instal this one "Kernel version 7.x is only for ported Samsung based Kitkat 4.4.4 roms (e.g. back-to-n00t)"

1. I don't know then. Why don't you try this rom if you think you'll like it?
2. You could, but first you need root and a custom recovery (if not already done). Greenify put apps running in background in hibernation, read its description.
3. If you read the OP, there are versions for 4.1, 4.3, 4.4.2 and 4.4.4
1. I've already installed this rom "Blekota Note 4 lite" , and as you see there is 5x5 on ss. But in my phone I've got 4x5.
And now I'm interested in how to set 5x5?
2. Already done all of stuff root + custom. I've already installed in my phone this ROM
The question is that is it possible without flashing all (rom + kernel), just kernel?
Greenify put apps running in background in hibernation, read its description.

Ok, so i try this one.
3. I've read all this stuff and faq, thx
BTW: It's not my first custom rom (and as you can see I do not know everything), but I had no need to register on this site beacuse site is free. And now I need to get 10 posts to write in direct topic
So I ask about that here.
1. Still don't know how?
For others,
2. Yes, you can flash kernel but restriction is to have the same Rom (4.4.4 -> 4.4.4) It concerns Boeffla Kernel
3. I think Boeffla Kernel is better than stock or arter kernel.

The 10 post rule applies only for development threads. Each ROM has its development thread and its Q&A thread. So you can ask questions about a ROM in its Q&A thread even if you don't have 10 posts yet.
If you want advices on how to write 10 posts without spamming, read this and that.
