[Q] Look over my gameplan please - AT&T Samsung Galaxy S II SGH-I777

A long time ago I rooted my phone via odin and then flashed a shostock ics rom to my sgh i777, after searching around on this forum I found out not to go on the website that I learned how to originally root/flash my phone, anyway here is my phones current information
android - 4.0.3
Kernel- [email protected]
Now im planning on switching over to the Siyah 4.3.3 kernel with micswap, and the AOKP Jellybean Build 11.9.2012 rom. Now from what I've gathered I simply both the kernel zip and rom zip over onto my phone. Using cwm I flash the kernel because odin only recognizes .tars iirc and then have it boot back into cwm and then flash the rom? Obvioulsy before i go through with it, i'll make the nandroid, and then do
1. Wipe cache
2. Wipe dalvik
3. If you are already on a previous version of Siyah, "Reset ExTweaks profiles" (its under "Kernel specific options")
4. Flash the kernel
Once i flash the kernel I should be able to flash over to the JB rom correct?

1) Copy ROM, Kernel and JellyBean GApps to your device in a place that's easy to find (I use root of internal SD)
2) Reboot into recovery
3) Make a nandroid backup
4) wipe data/factory reset
5) wipe cache
6) wipe dalvik cache
7) reset extweaks profiles
8) install ROM zip from internal
9) install JB GApps
10) install Siyah 4.3.3 micswap if you want - but you won't get support in the AOKP thread if you do this.
11) reboot device
If you flash a kernel before a ROM, the kernel included in the ROM will overwrite the one you just flashed.

I was under the impression I need the micswap in order to use the rom I want? You mentioned I can use it if I want but I just wont get support in the thread so I tried researching the whole micswap thing, well Im still a little confused because some say you need it for the i9100 phones. Well mine is an sgh i777.. but after I originally flashed it with odin whenever I booted it, it comes up with the i9100 logo, so Im a little confused now because in the siyah thread it says I need the micswap to run the rom I want (AOKP Jellybean 11.9.2012).
I downloaded the v4.3.3 - CM10/AOKP MALI - CWM Flashable kernel with the micswap. Either way cant I just put the other 2 v4.3.3 ICS Micswap and no miccswap kernels onto my internal SD and then flash them if I have to?
edit - heres another problem I just ran into I just found a siyah v5 in this thread It has both micswap and no micswap versions, It mentions to use the micswap for anything AOKP based, since the JB rom Im using is AOKP based I would need the micswap version, but now im assuming the siyah v5 kernel is better then the v4.3.3 right? But i cant seem to find like a release thread of the v5

I noticed you have the same att phone as i do and you're running the 4.3.3 kernel are you using the micswap version or the without micswap?

Reading is your friend here - spend LOTS of time doing this BEFORE flashing to know what you are getting into. But the short answer to your questions above:
There are mic-swap and non-mic-swap versions of most of the kernels for the i777. if you are using a rom based on an i777 samsung release, you need NON-mic swap. If you are using a ROM based on i9100 Samsung release, or AOKP, or CM, or AOSP, or pretty much anything else, you need mic-swap. Any ROM you install will include a kernel with the appropriate swap settings. You are best off running whatever kernel comes with the ROM you flash at least at first, and then try something else if you want additional functionality or want to see if you can improve performance. If you flash some other kernel over a ROM, the ROM dev will likely not provide any support becuase you are messing with what they release - this sometimes results in bugs/erratic behavior. It's up to you at this point to research/read/try stuff to sort out your problems.
The latest siyah ported and modded by Ktoonsez is 4.3.3. Ktoonsez adds some stuff to 'stock' siyah, so many people use that. 5.0.1 Siyah was ported by AJ, with, as far as I know, only minimal changes. it is more of a 'stock' siyah, but a newer version. You need to research the two yourself to decide which is better for you based on their features. you do this by reading at LEAST the first 10 posts and last 200 posts (yes, last 20 pages) to get an idea of the history and ongoing issues for each. You should be doing that for any ROM you are thinking of flashing too. If you're not willing to spend at least that much time to benefit yourself, it's not fair to expect anyone here to spend their time helping you.
If you have an i9100 logo at boot, it means you flashed non-stock via odin and triggered the counter. This won't hurt you at all unless you need to return the device for warranty issues, or if it annoys you. There are plenty of threads around here with the means to get rid of it - search is your friend here.

Thanks for the quick response and yeah im not too worried about about the counter. I appreciate you clearing up that each rom has its own kernel for some reason I thought you need to match a kernel/rom. For now i'll just try the aokp rom and then maybe switch over to the siyah 4.3.3 after doing more research. I just went through with flashing just the rom and gapps now time to spend an hour in the bathroom figuring everything out. Anyway thanks for the help i'll definitely do more research into android. Computers were my hobby for the longest period of time untill I got into cars, trying to pick up phones now even though im pretty late to the party.
How are you liking the Ktoonsez Siyah 4.3.3?

rom/kernel question

So I had followed a guide (GalaxyS2Root.com i think the site was) for rooting my phone and successfully rooted my i777 device. Had no problems.
Upon researching this forum to start figuring out what else was possible with my phone, I found some information on what I had just installed and learned a few things and decided I wanted to install a custom ROM (but, I haven't gotten around to doing it yet)
So the package I had used to root my phone (which is using the AT&T-provided ICS rom) was "Siyah-v3.4.2-nomswap-I777.tar".
I noticed the "nomswap" in the name as well as the version.
I read a few peoples' posts asking about JB roms, and some replied that mic swap is required for all JB roms.
So, my questions:
1) I need to install an MSWAP kernel first before a JB rom? Or the other way around, rom first, then the MSWAP kernel?
2) If I install the MSWAP kernel but choose not to install a JB rom all the sudden, will my stock AT&T ICS rom continue to work fine?
3) Do I require the updated Siyah 4.3.3 kernel for the new JB roms?
Thanks.
The determining factor for whether or not you need mic swap is the ROM's base. Android version has nothing to do with it - some JB ROMs will require mic swap, others will not. Mic swap is for ROMs built on I9100 or AOSP base; without mic swap is for ROMs built on I777 base.
You should understand that every ROM is packaged with a working kernel, so there is no need to flash a different kernel on top of it. However, if you prefer a different kernel, you can always flash it after flashing the ROM.

You should have the most up to date kernel in general. All roms are packaged with kernels already otherwise it wouldn't run at all, so it overrides whatever is already there. And DO NOT USE ANYTHING FROM GALAXYS2ROOT. For the rest, you'll have to use Google as I've done my spoonfeeding for today.

Also as a side note. Any of the leaks require u run the kernel the rom comes with . As in Siyah and Dream won't work with the leaks yet.
Thank you for all the information. Very useful.
On a side, I only learned of XDA and the AOKP ROM as a result of reading GalaxyS2Root.com.
So basically, with every release of a ROM, I can just flash it and be OK. I don't need to manually change the kernel beyond flashing the ROM itself...
If that is the case, what is the purpose of the kernel downloads (Siyah 4.3.3 or the sort)?

Because not all roms use Siyah as a kernel but it can be flashed separately.

[Q] Little help flashing to cyanogen

Hey guys.
I just bought a samsung tab 2 10.1 and want to flash it to cyanogen to get the multiple users that comes with android 4.2.x
I havent flashed in a while since i updated my i9100 to 4.1.2, so i thought best to flash my i9100 to cyanogen first to try it out as my phone is already rooted. I found a few guides for installing cyanogen to my phone using cwm recovery to install from the SD card.
I remember rooting my device back when i updated it to 4.1.2 but when i tried to boot into cwm is would boot into the stock android recovery.
so i figured i needed to flash cwm recovery.
after checking all kies processes were stopped i flashed the kernel "GT-I9100_ClockworkMod-Recovery_4.0.1.4" , but the phone would not boot and hang at start screen.. as a plus side i now had access to cwm recovery from boot... ironic.
so i booted into cwm recovery thinking to install cyanogen mod as i thought maybe the rom wasn't compatible with the kernel?
but noticed that the cyanogen rom was not present on the menu in cwm recovery, must of put it in the wrong place. I was now thinking to get my phone to boot into 4.1.2 that should still be on the phone, since the current kernel wasn't working i flashed "Siyah-v5-MCM-i9100-vsync_sysfs-20130217" in hopes it would be compatible.. still no luck with it booting. but i still have access to CWM recovery.
Any thoughts on how i should proceed? if i can get cyanogen onto the SD card should i install it via CWM?
little lost at the moment. been a while since i done all this.
here is the information i noted down before i started today.
4.1.2
i9100xxls8
3.0.31-863787 [email protected] #3 smp preempt thu jan 31 12:20:07 kst 2013
JZO54K.I9100xxms1
Thanks for reading.

Philz kernel lss flash that through odin. Reboot to recovery, do the wipes and and reboot. 4.1.2 should boot up then. Then move custom rom to int sd and flash away. Philz installs custom cwm. Once you have flash custom rom philz will be replaced with stock custom kernel with cwm built in to it.

I'll give it a shot, is the Philz kernel you mentioned this one?;
<< 03.06.2013 - PhilZ-cwm6 v5.06.1 with CWM 6.0.3.2 based recovery >>
I'm not to sure what kernel version i need.
how would i find out this information ?
Many thanks.
Edit:
I noticed in my previous notes i made when first flashing my phone a year or so ago. The kernel i used was this;
3.0.15-I9100BGLP8-CL317471 [email protected]#3
It is now kernel version;
3.0.31-863787 [email protected] #3 smp preempt thu jan 31 12:20:07 kst 2013
which has no reference to previous kernels. but my current baseband version is: i9100xxls8
LS8 stands out in both... so would using PhilZ-cwm6-XWLSY-ORA-5.10.0.tar.md5 work on my phone?
Lss will work as it for 4.1.2 it just has newer cwm installed.tar is for odin. You could get the zip one and put on an sd card put bk in your phone and flash it like that. Make sure its zip not tar for flashing in cwm.
Thanks

Thanks, that worked. opted for no installing the nightly version of cyanogenmod as i would like something more stable on my phone.
I've been looking at Resurrection Remix 3.1.2 or CM1UI Jelly Bean.
Is the Philz kernel i installed a widely compatible kernel or should i install Siyah ? my last attempt to install Siyah kernel lead me to write this post.. how would i go about installing a more widely compatible kernal with out ending up in a hang screen again ?
Kind regards and many thanks.

By 'compatible', you mean the kernel works with many ROMs?
Philz is a stock based kernel. So it only works on stock based ROMs, and depends on the android version and the build versions (like LSS, LSJ, LSD etc). Siyah is more compatible, because it only depends on the android version (like JB, ICS or GB).
You had a bootloop before after flashing Siyah mcm kernel, because the mcm kernel supports AOSP 4.2.2 ROMs, not stock JB.

To avoid bootloops after flashing a kernel, use these tips:
1. Flash only kernels supported by your current firmware. Suppose you are running stock JB and you want to flash AOSP 4.2.2 ROM. You might be tempted to flash Siyah mcm kernel (because it supports AOSP 4.2.2). But that would end up in a bootloop as Siyah mcm doesn't support stock JB! :good:
2. Use a kernel cleaning script before flashing any kernels. :good:

Thanks for your reply, i have a few questions to try and understand.
Would i be right in saying;
When im looking to install a new kernel and/or Rom. My check list should be;
1. Kernel to phone compatability. I.e my phone is LS8 so i look for LSS/LSY/LSD soforth and so-on.
2. Kernel to Romcompatability. I.e Philz is a stock kernal hence why it works with 4.1.2 stock Rom.
So if i want to install Resurection Remixed i believe its a modified stock Rom so it should work with Philz?
As would cyanogenmod as it is modified stock?
Or is even that modified to much?
If i want to change both kernel and Rom, would it work if i installed for example siyah kernel then boot into CWM recovery and installed from there a new Rom?
Im looking to try out a few roms on my i9100, mainly Reserection remix, and other cyanogenmod clones with light modification as i enjoy the stock android experiance.
Also looking to install cyanogenmod to my p5100 tab. Flashing Philz p5100 kernal and then installing superuser through recovery and then installing cyanogenmod 10 stable version?
thanks for reading and taking the time to anwser my previous questions.
Many thanks

Don't worry, things can be a bit hard to digest at first.
Let me make it easier:
1. U are currently using a stock or custom ROM, but you want to change the kernel (without any plans to flash a new ROM). In this case, you need to select a kernel that is compatible with your current ROM.
2. U are on a stock ROM, and you need to flash a custom ROM. You want to flash a kernel to root it and install CWM (to enable u to flash a new ROM). In this case also, u should flash a kernel that supports your current stock ROM.
3. U are on a custom ROM, and you want to try another custom ROM (which may require another kernel to support it). In this case, you DON'T need to flash a new kernel that will support ur new ROM. You can flash the new ROM directly. All custom ROMs come with their own supported kernels bundled in the ROM. So, after flashing the new ROM, your current kernel will be REPLACED by a supported one from the new ROM.
Better?

So my breakdown would be I'm using a Stock ROM with Philz kernel rooted and CWM. I want to Install Resurrection Remix which is a 4.2.x ROM, Philz is a 4.1.x Kernel so i need to install a new kernel to support Resurrection Remix? or would that come with its own Kernel?
And for my tablet. I flash Philz kernel and install superuser to root the device. so now its stock Rom with Philz kernel. So when i install Cyanogenmod Rom it will install its own Kernel or do i also need to install a Kernel that supports 4.2.x?
Or is it Firmware version based Kernel updates that happen when you install and new custom ROM?
i.e Running 4.1.x kernel and installing a 4.1.x Custom ROM will update the kernel, but installing a 4.2.x ROM will not?
vice versa Running a 4.2.x kernel and installing a 4.2.x ROM will update the kernel, but installing a 4.1.x ROM will not?
Kind Regards, I appreciate your time for reading my mind numbing questions.

For you i9100 just flash the rom using philz cmw recovery and once its done you will have a custom rom with custom cm kernel which is rooted and has cwm with it. I would say to format system ,data, cache and preload before you flash it using philz recovery and make sure the rom and gapps is on int sd card were you can find it.
As for the tablet make sure philz is compatible with that tablet first!! Dont just flash it on that thinking because its 4.1.2 it will work.
Btw with philz also come with root access too.

No, you don't need to install a new kernel, because flashing RR will flash a compatible kernel (included in the ROM) by itself. :good:

Don't overcomplicate stuff mate. When you flash a ROM, the kernel contained in the ROM will be replace your current kernel. Simple.
Thanks a lot!!!
I installed RR to my i9100 and cm10.1 to my p5100.
I'm having a little trouble with i9100 device though, I keep getting random sim locks on the device.. Not sure what could be causing it. It didn't happen on stock 4.1.2.
The devices will be locked and when I wake it I get prompted for the sim lock code. I now have the sim lock on my phone deactivated but I'm fearful that even thought I am not getting prompted for the sim code, the sim could be de-activated while the phone is in sleep thus not connect to the network?
Could be a loss of signal activate a security feature of the sim. Or a problem with the kernel?
Kind regards.
Many many thanks for all your advice into helping me understand a little better.

Sent from my GT-P5100 using xda app-developers app
If you're sim locked, then you want the app 'Galaxsim unlock'. Search for the xda thread, the OP is spocky12 if that helps you find it. It won't be kernel related. And, test it for yourself. See if you get messages /calls / push notifications while your screen is off & phone is sleeping.
Sent from a galaxy far, far away
The i9100 was originally sim locked, but I paid someone to unlock it, once I got the phone back from him "unlocking" it. It was apparent that he has flashed the device with a new kernel and ROM in order to unlock it... Not to sure of the process. A couple months later I flashed 4.1.2 as it wasn't available as a update on the ROM he installed. The phone re-sim locked and I downloaded the app you mentioned and unlocked the phone successfully, been happily using it up until I installed RR. Now I'm suffering from random pin locks. The phone connects to the network and functions perfectly, apart from said sim locks.
My only fear is missing important calls if this lock is causing network disconnections. Can I log network functions and connectivity to see what's causing it?

[Q] Changing ROM changes recovery as well?

Hi!
I am new to this phone an I am confused about one thing. With my previous phone, I installed any ROM that I wanted, and the cwm recovery would be the same, and will not be affected at all. But, I changed my ROM to PACman ROM and I noticed that the cwm recovery version changed as well.
So, I have three questions:
- Firstly, How does this work? I opened up a ROM zip package, but I only found the regular android files, but I didn't find any recovery.img. So, how does replacing the ROM replace the recovery work when a ROM is flashed?
- Secondly, does changing only the kernel also change the cwm recovery? For example, if I flash Dorimanx kernel, will it also change the cwm recovery? If yes, then how does this work?
- Lastly, if I build a ROM, is it necessary to add a recovery with the ROM as well? Or, if I build a ROM without recovery, will it affect the recovery when it is flashed?
I know that these questions might have long answers, but I am keen to know the answers, no matter how long they are.
Please try to answer all three of the questions. Or, answer as many as you can, because those questions regarding the changing of cwm recovery is very confusing.
Thank You.
Hello, congrats on your new phone Unfortunately, i can't give you lenghty information about this because i don't think i know that much, but here are some facts for you:
-When you flash a new ROM, it will overwrite kernel too, so you will have a new kernel,
-When you flash a new kernel, it will overwrite the recovery, so you will have a new recovery,for example if A kernel has cwm as recovery, if you flash A kernel you will have cwm, and if B kernel has TWRP as recovery, when you flash B kernel you will have TWRP recovery,
-Since you have to have a kernel for your ROM, if you build a ROM, you must have a kernel=recovery, you can build the kernel yourself or use someone's kernel, but recovery must be embedded in the kernel (As far as i know)
When you start building your own ROM, i think you will find out the "how"s yourself though

That was short, but it does kind of make sense. Since I am using CM kernel right now, I guess the recovery will already be in there. But, If I want to create my own kernel from scratch, then are there any guides or information pages that give me an idea on how to do it?
Thanks.
All that stuff is in the development sections (where the devs live), Q&A is the wrong place for stuff like this (Q&A is for n00bs with busted phones). Google/XDA search for specifics or maybe ask a few devs in the threads devoted to their kernels/roms.
Yep, the recovery will be embedded to kernel. Here is the index of guides: http://forum.xda-developers.com/showthread.php?t=1826497 (thanks to pelpa87)
Index of kernels: http://forum.xda-developers.com/showthread.php?t=1702166 (thanks to GaboWinter)
I use G variant and there is a nice tutorial for us, you can read and see if there is anything you want to learn from there : http://forum.xda-developers.com/showthread.php?t=2495727 (thanks to Black_Prince)

But, if, for example, I install dorimanx kernel, then the recovery embedded in dorimanx kernel will be installed. So, if I dualboot a second ROM from dorimanx recovery, then the recovery from the second ROM would be installed. That would mean that I won't be able to dualboot again?
Hmm, i think dualbooting has some different mechanisms, since you dual boot you have to have ONE kernel that supports dual boot, recovery will be the same since kernel is the same. So basically, you have A rom which has A kernel, then you flash B rom which has B kernel to dualboot, but there can't be two kernels at the same time so you must choose between A kernel or B kernel (both has to support dualboot ofc), and since recovery is embedded in kernel, you will have A recovery or B recovery, not both.

[Get a noob started] The basics - 3 questions

Hi everyone!
Let me start off by saying that I am not one of those who directly ask questions before reading. Honestly, I have been reading from guide to guide and it is because of the many guides on the forum and Google that I have become confused on where to start.
I have rooted and flashed ROMs + kernels on my old phone, so I know most of how it works, but its the first time I use a Samsung phone, so I would really love some help to get started.
All in all, I have only few questions, but important ones I would love to be covered. Better safe than sorry, right?
Let's get started:
I am currently running stock JB - to get root I shall just flash CF-Root, or is anything else recommended?
Once rooted, is there any recovery I shall use that is more "stable" than any other? CWM, CWM Touch, TWRP etc.? Lets say I want to try NeatROM + Apolo kernel, will that require any specific recovery?
If I want to try different ROMs out, like to go from NeatROM to SlimBean to CM11, can I do all that by using the same recovery? I know about the full wipes, I just want to make sure I can flash other ROMs straight away or if I need to change things before?
That is all for now. Once this is covered up, I highly believe I can take care of myself in this huge community and to help others too once I get a little experienced
I say thanks in advance! Absolutely loving the forum here
Hmm,as all your questions are somehow recovery/kernel related,you may try flashing Philz kernel.It's basically a stock kernel+advanced cwm recovery.You'll get root too.Its cwm can flash all roms up to android 4.3.1.I would call this option a safe and easy bet.
Also,if you want to try kitkat roms,like cm11,you'll have to update to kitkat compatible recovery,like cwm 6.0.4.7 etc,first.

Thanks for the reply! Appreciate the help! From what I can see, that also roots the phone, so this could be the easiest way to go :good:
I assume you refer to this thread? http://forum.xda-developers.com/gal...lz-cwm6-stock-kernel-cwm6-root-exfat-t1877270
The latest build alone has all these builds lol:
PhilZ-cwm6-XWMS2-MOT-5.15.9.tar.md5
PhilZ-cwm6-XWMS2-MOT-5.15.9-signed.zip
PhilZ-cwm6-XWMS1-NEE-5.15.9-signed.zip
PhilZ-cwm6-XWMS1-NEE-5.15.9.tar.md5
PhilZ-cwm6-XWLSZ-OJC-5.15.9.tar.md5
PhilZ-cwm6-XWLSZ-OJC-5.15.9-signed.zip
Honestly, in the thread OP says this but I really need help to understand this further:
Phil3759 said:
What kernel to choose:
The important part is the Kernel code:
XWLPX-NEE
Kernel code is in red (LPX), for this example, you need an LPX ROM. However, often, you can mix kernels when they are close: LPF kernel with LPG ROM...
NEE code doesn't matter at all, I add it for reference. It is the CSC
XW: mixed, often doesn't matter for close regions. For example, XW and XX are often interchangeable. However, mixing a BU with an XW ROM or inversly, sometimes works, but often ends in a bootloop. In that case, either boot into recovery or download mode to reflash

And one more question: It says cwm6, does this mean I shall use this recovery for JB or KK ROMs?
I am getting close to flashing, just need this final step
Look at your rom's build number and choose accordingly.To check,go to settings/about device.
Use this kernel only for stock/stock based JB or ICS,as it has older,kitkat incompatible, CWM.
To flash 4.4.x roms,you can do it by following these simple steps:
1.Download a 6.0.4.x or newer CWM for i9100.
2.Boot to Philz recovery.Do a nandroid backup.
3.Flash new CWM.
4.Reboot recovery.
5.Full wipe,then flash chosed kitkat rom+gapps.
6.Reboot and enjoy!!
Ok that is great help mate. Youre great person!
I just didnt quiet get the custom JB part then, to flash a custom JB such as the one on your signature, SlimSaber 4.3, I shall use...?
I promise this is the last question then I am good to go all thanks to you
With the CWM 6.0.3.2,which is latest in Philz kernel,you can flash all Jelly Bean roms(4.1.x to 4.3.1).This includes both stock samsung 4.1.2 Jelly Bean and custom JB roms,like AOSP(that SlimSaber 4.3.1 is),CM,AOKP and so on...Just no KitKat love.
Don't forget to do a nandroid backup and EFS(this is vital) backup in recovery before you start. Just in case you know.
Good luck!

Kernel and recovery

Hi,
I wish to install a newer ROM than the one I currently have, yet it seems I might need a new kernel and CWM instead if TWRP.
So my questions are:
1. How do I know if I need a new kernel?
2. At some kernel threads, it is said that they only work with kitkat ROMs for example, and other ROMs might brick the phone with this kernel.
So do I flash a new kernel first or a new ROM first? Basically, how do I not brick my phone?
3. I read somewhere that SGS2 users can't install recovery without installing a new kernel. Is it true?
4. I would appreciate some directions about installing a new recovery (I would probably need CWM).
5. Why is it so hard to find answers to these probably many times asked questions?
Thanks.

1 - if you are happy with your current rom, dont flash a kernel if not sure what you are doing!
2 - kk and LP kernels are not compatible between them as your cpu doesn't fit in a incompatible motherboard ! newer kernels are safe from brickbug ! you wont brick your phone with a wrong kernel (kk kernel over LP rom), just a bootloop.
3 - because a kernel is a recovery and a recovery is a kernel.
4 - Slimsaber is a good rom to start see first and second post
5 - is not hard to find if you know were to look!

Just a small correction. A recovery (CWM or TWRP) can not be installed by itself because we don't have a recovery partition. Therefore kernel with a custom recovery needs to be installed.

1. I am happy with the current ROM, yet I want to flash the kernel to fix the annoying FPBug and to finally get LP ROM. And I might not know what am I doing, but if I won't try I will never know
I've flashed a new kernel and a new LP ROM, and I'm trying some others.
I still find it difficult to find a kernel that answers my needs since many kernels are hiding in specific posts and some kernel threads doesn't mention which recovery they install.
