I'm trying to root+cwm my brother's sgs2 to bring it back to life (so much lagg).
I've done this with my sgs3 but it's tedious trying to find the right method and files for this particular device.
I have searched these forums but am not reassured that I'm going about this the right way to get the rooting process over and done with as there doesnt seem to be much info on rooting 4.1.2. Better to be safe and ask than to be sorry...
Device Info:
PDA: i9100XWLSD
Phone: i9100XXLS8
CSC: i9100ojvls6
Basebrand: i9100XXLS8
Build: JZO54KJ9100XWLSD
Kernel: 3.0.31-889555 dpi @ dell 228 #3 smp preempt TJ31 14 48 54 KST 2013
Android version: 4.1.2
This thread says I have to look under kernel version for something similar to 2.6.35.7-I9100XXKG1-CL349526 but this info seems to have been moved from kernel version with 4.1.2.
I'm guessing that i should use CF-Root-SGS2_XW_OJV_KF1-v4.0-CWM4.zip based on my CSC but don't see anywhere in this thread if I can use this rooting method for 4.1.2.
This thread also asks you to look at kernel code similar to XWLPX-NEE but this does not exist under kernel version on my phone. Now I'm not sure if I should use XWLSD (bootloop fixed) or XXLS8-FOP (Jellybean) as both of these are relevant to my device info.
Or should i use this method and run superoneclick later?
Any clarification would be thanked and appreciated!

use a custom kernel (eg siyah,dorimanx...etc)that comes pro-rooted and CWM installed.
link for dorimanx kernel http://forum.xda-developers.com/showthread.php?t=1617219
link for siyah kernel http://forum.xda-developers.com/showthread.php?t=1555259
download the TAR version of the kernel and flash it with odin 3.07.
how to use odin:
download odin http://d-h.st/SdH
boot your phone in download mode (Press and hold the Volume Down key, Home button (middle key), and Power button simultaneously. A warning message will appear on the next screen. Press the Volume Up key to continue).
open odin,click on PDA,choose your downloaded kernel,and start flashing.
hope it helps.
No problem asking, but its not that there isnt much info about rooting, its that there is far too much.
My answer depends on exactly what you want, with a view to present and future desires.
If you want root and cwm you can flash apollo/siyah or philz kernel.You can do it by odin, or see what signed zips are available to use stock recovery.
You should also run a kernel cleaning script.
So what you're saying is kernel version, csc etc. all dont matter as long as its simply an i9100 running 4.1.2 when using the above siyah/dorimanx/phillz methods?
I intend to keep it as stock as possible (my bro's terrified of rooting) until he sees its safe and wants features only available in other roms at which point i'll probably use cyanogenmod with no custom kernels.
My question (how to root when on 4.1.2 for my particular hardware) is probably what most new rooters for the i9100 come to this section of the forum for today. But unfortunately the stickies give you the idea 'do not use this method unless made for your exact device!!'
or maybe its just me...
i think i'll go the philz route for pure stock experience. i have trouble figuring out which version i need based on what my about page says:
XWLSD (bootloop fixed)
or
XXLS8-FOP (Jellybean)
??

Wow i don't know what you guys are talking about
But if you just need to root your device why don't you try
https://forum.xda-developers.com/showthread.php?t=2130276
1-klick and root
And if you need to install cwm you just have to download rom manager from playstore - he will automatically install the latest cwm for your device

No. Do not use Rom Manager on the I9100/T/G/M/P. At all. Ever. It will break recovery/cause bootloops eventually, which will require an wipe and/or an Odin flash to recover.
Besides, any recovery flashed on its own on this phone will only persist until the next reboot anyway, due to recovery being baked into the kernel/not on a separate partition like many other devices.
Flash a custom kernel of your choice = rooted phone + CWM & you can then flash whatever custom rom/kernel you want from there. No need to flash CWM separately.

Didn't know it shouldn't be used on these models, only tested it with my phone.
however how do i know which model he is using? I'm a bit confused know
Nevertheless, sry for giving false information, never would have thought it could break the phone cause it says in rom manager it will find the fitting cwm ...:screwy:

All good Yeah, Rom Manager breaks stuff. You might get away with using it for a while (maybe even a long while), but in most cases it do the things I mentioned sooner or later. CWM has everything you need anyway.
How do you know what model someone is using ? Ask them.

Well this didn't go at all as I'd hoped even if it could be worse:
-rooted using Philz XWLSD (fixed for bootloop) and confirmed supersu was working
-made a nandroid backup in philz
-did a data wipe>clean for new rom as planning to install cm 10.1.3
-wiped cache & dalvik cache
-realized i should probably make a 'clean' stock version first to give my bro the option of choosing stock or cm
-restored the nandroid and rebooted
Now I'm stuck at the samsung logo on boot. Not sure how to go forward as this is my first boot issue ever after flashing 50+ roms on the s3 using cwm.
Installing cm thereafter resulted in no issues but it'd be nice to know i could go back to stock if my bro wanted

Well i don't really see a reason why the restore didn't work. I would try to make a complete wipe after restoring and than run the backup again...sometimes that helps ...
If no try to flash a custom rom first with the same Android version like ur stock rom and afterwards try to restore ....
It sounds not very logical but i had to do that often :banghead:

Apparently the problem was that philz does not backup the /preload/ partition by default which results in the bootloop. The only possibility is flashing the original fw via odin and trying to integrate that /preload/ partition with my current (incomplete) nandroid. Will need some time to test this as my brother is currently quite happy with cm.
Yeah.....I've run into that preload issue with PhilZ myself........
There is a thread on here by Chainfire for one of his creations called mobile Odin.....it allows you to flash a firmware 'in phone' without the use of a PC or PC based Odin.......
With regards to integrating two partial backups.....I'd be surprised if that worked.....integration IS probably possible..... But then you have to modify the MD5 file in order for the recovery to accept and flash the integrated backup.....from what I understand, the MD5 acts *like* a numerical 'bar code'.......
In the same way that a bar code is linked to a specific product, the MD5 is linked to a specific backup or other flashable zip.....I believe it 'encodes' the size, number of folders/files etc......if the MD5 info is a mismatch to the zip, cwm 'scratches it's head' and refuses to flash it........

hi, sorry for the noobish questions. :L
i have a couple of questions, i have heard about checkrom but i havent been able to really find out what it is, could someone please tell me ?
my other question is would i be able to flash miui on my phone?
my phone's details are:
model number: GT-I9100P
Android version: 2.3.4
baseband version: I9100PBVKI2
kernel version: 2.6.35.7-I9100PBVKI3-CL608158 [email protected] #2
build number: GINGERBREAD.BVKI3
it's the nfc model locked on orange uk.
thanks
You need a P rom to flash as far as we know so far .If you flash a wrong firmware you can brick your phone .
Checkrom is a custom rom if you go to the Checkrom post in the developers thread it wil giver you a descriptions . Same goes for all custom roms page one this rom is and has the following or not .

You can only flash a P rom unless you find evidence to the contrary . Most roms are for i9100 version .
Or be a guinea pig and try .

You can flash 9100 ROM on your 9100P
But 9100 ROMs don't support NFC module (it will be supported natively with ICS).
I have the same device (orange FR) and you can look my signature for working Radio + ROM...

I dont remember
But if your device is already rooted you can install Rom manager or CWM from the market and make a backup of your config. Then reboot in CWM and install what you want (read the how to install section of the wanted rom).
Don't care about your "P" version!
What you read here for standard device (i9100) is working for your P version.

Don't use Rom Manager, use Clockwork. Rom Manager seems to not work well with the SGS2, this forum is littered with posts from people who used Rom Manager to flash and it broke CW Recovery, put the phone into a bootloop or soft brick, etc, etc.
Best to play it safe IMHO.

Oh I didn't know that rom manager was not working fine on our device. I am using clockwork manager and it is working fine.
I've seen a heap of posts in the couple of months I've been visiting this forum from people who ended up with broken CW Recovery & bootloops after using the Manager app.
I used it once to try and flash a kernel & it broke recovery completely.
Obviously any/everyone's mileage may vary, but for me, I'd rather play safe & boot into Recovery whenever I flash or backup.

Didn't say you shouldn't use it Just said that plenty of people have had problems using the app, and rather than risk it, since I had that problem with it, every time I've done a backup or flashed a rom/kernel I've rebooted into recovery & used CW Recovery itself to do the business
As I said in my previous post, your mileage may vary & you may not have any problems with it at all.

Hello guys! I have a GT-I9100P also with the latest BVKL2 2.3.6 firmware. I had it rooted when I was at BVKI3 2.3.4 firmware and now I am looking for a good CF-ROOT kernel for my phone. What would you recommend me? (what if I tell Chainfire to make a CF-ROOT more appropriate to my kernel)?

Why don't you post in Chainfire's thread to ask him about making an insecure KL2 kernel?
But I think you can use the insecure KL1 kernel from Chainfire's thread to use for root. Or you could flash SpeedMod or Siyah, and the rooting will happen for you. You have lots of options.
were to put the rom zip file
I got the exact same phone as the OP im trying to flash a rom in a zip format but clockwork mod recovery cant find the file ive looked in install from sd card and install update.zip. ive also tried installing it through rom manager, no joy there, inside rom manager i chose to boot into recovery to flash it manually and now i got a black screen with a white triangle n a lil green android dude so i see what people are saying about the s2 and rom manager, anyways my question is were do i place the zipped rom? on the internal or external and should i rename the rom file?
Ive had 2yrs experience with a HTC HD2 so im not exactly a noob to flashing roms, but the galaxy s2 is very new to me.
Hi!
I was hesitant to open a new thread, especially since I watched the noob video before registration. But since I really want to make sure that what I am doing is correct, I have decided to post this.
I have SGS2-I9100 with ICS (so my firmware version is XWLPD). I will be using this tutorial to root my phone (How to Root Galaxy S2 i9100! [ICS][Android 4.0+] -on galaxys2root dot com) I am familiar with the basic terminology and also understand the principles of rooting. However, I do have a question about which CF-kernel am I supposed to flash. I found two of those (v5.3 and v5.4):
From the tutorial (i can't post outside links) - v5.3
And from Android authority - v5.4
Which one should i use and are they both ok with XWLPD firmwares?
(And don't I need an original kernel after the rooting? With previous tutorials, there was always an insecure and a secure kernel)
And after the device is rooted, what is the best thing to do? I am thinking: first I would flash Clockworkmod Recovery 4.0.1.4 (and backup my original ROM), and then install TITANIUM BACKUP for contacts, apps etc. Is that good?
I really appreciate all your help!

I am not sure about CF-Root, but I recommend siyah kernels because its safer. It should also work with your firmware version. If you are on 4.0.4, best not to have CF-Root and wipe data through CWM since you might brick your phone. CWM also comes with siyah
Sent from my potato.
I have 4.0.3.
Thank you for your answer!
however...
Well, this has confused me a little.
So instead of CF-kernel I should use Siyah kernel? (@ gohkanmoral dot com right?). And then flash it with ODIN 1.85. And that is it?
And CWM is allready a part of the kernel, so if power off my phone then i can reboot into ClockworkMod Recovery by holding down Volume Down, Home button, and Power button together?
I am sorry for my lack of understanding.

Yes, u can use Siyah kernel V4.1.5 from www.gohkanmoral.com ( u should Dwnld the file from 'Download Tar (for Odin) link).
this kernel will root ur phone running Ics 4.0.3 and will also install the latest 6.x Recovery and also a dedicated 'CWM' app in ur app drawer which u can use to boot into recovery
Ps- its always better to clarify if in doubt rather than getting Stuck!!

Your original ROM doesn't matter. Just make sure your kernel supports the custom ROM then it will work.

the best way to say what is your best option is to try ROM by ROM
seriously, read the descriptions and choose the one that fits your needs, but before flashing new roms always do a nandroid backup, so you can restore your previous rom in case of troubles or if you just not like the new one
hi guys,
i have a samsung galaxy s2 (GT-i9100 - NFC), which i got from orange end of 2011. I the in jan 2012 got help from this forum to root my phone and change the rom from the original to:-
Rom & Build No: VillianROM 3.0
And' ver: 2.3.5
Baseband: i9100XXki1
Kernel: 2.6.35.11-ninphetamine-2.0.5+ninpo @ titan #20
Although the phone works okay, i'm beginning to notice a lot of slowdowns and regular reboots, so i want to go back to whatever latest google android OS the S2 can handle (rooted). I've forgotten what to do and would be most grateful if someone could please help me with the following:-
1. Whats the best software/method to backup everything?
2. What is the latest rom (original, but should not have a provider's bloatware) i can use on the S2?
3. Once backed up, how do i change from VillianRom to the latest/best OS currently available?
4. How can i root the original rom?

1. Depends. You can do a backup in CWM to image your device or you can use Titanium Backup Pro to just backup your apps/appdata and restore to new rom.
2. http://www.sammobile.com/firmware/ < Check your device/model here.
3. Well just so you're clear, There is no "best" its subjective. Also "latest" depends on what type of rom you want to flash like Sammy/AOSP/AOKP/CM/MIUI etc. To flash latest samsung do it via ODIN, to flash any other do it via CWM. All info you need is already on forum.
4. By flashing custom kernel via ODIN.
All your questions have already been answered countless times.
Thanks very much guys. I simply want a fast lean rom as some seem to be slow running.
Doesn't get better than this.
sendign the phone for warranty?
you will need to flash back the original rom and unroot your phone.
if they found your phone is rooted the warranty void, experience it before so be aware of this.
Let me thank you guys for advicing me. I am most grateful. I read your posts a bit late and in the meantime, I think i have bricked my phone as i've flashed Samsung's original FW (I9100PBVLP8_I9100PORALP8_ORA) from sammobile.com. I used Odin v3 and successfully flashed the phone, but it's simply stuck on the boot logo. I have even done the following:-
I've managed to wipe the cache partition, but the recovery menu has No advanced options. It says:-
ANDROID SYSTEM RECOVERY <3a>
reboot system now
apply update from ext' storage
wipe data/factory reset
wipe cache partition
apply update from cache
test redband fota[FS]
But i still cannot get it to boot. I have also tried to use an old nandroid.md5 backup i made, but odin reports the file as invalid.
I'm desperate guys, please could someone help me.
Download Mode and re flash.
Are you sure you are flashing the right ROM right? Check under the battery to see the Device Model.
If it's i9100, then make sure you are downloading a i9100 ROM.
Thanks very much for your advice gastonw - i have managed to fix the problem now by going into system recovery and doing a factory reset, so thank you.
Although everything seems to be working fine, i would have preferred a more newer 4.2 jelly bean rather than 4.0.3. Oh well beggars can't be choosers and all that, lol! I guess i'll have to re-root it again.
gastonw mate ur a star! I've installed the latest JB rom u posted earlier and i'm very happy with it.
Now before i damage it beyond repair, how do i root it safely?

Hi You could try this method http://forum.xda-developers.com/showthread.php?t=1501719 its quite safe so ether should work or wont, if don't no harm done as it doesn't need a insecure kernel.
I'm quite new myself @ this so plz use caution when trying it out.
Peace

Good to know man, enjoy it
About root, I've seen a couple of methods laying around the threads, I'm sure they're safe.
I still think that ExynosAbuse app is the fastest way to Root now (one-click).
Here's a vid. I never tried it tho.
Thanks very much for the links AnubuRe and Gastonw.
Gastonw mate, i have been playing with the rom you posted a link to. Don't get me wrong, it's great and very fast, but the downside is that it doesn't have a huge number of options to tweak etc. Now someone mentioned a rom called Neatrom, but i'm wondering what you can recommend? I don't want a bloated rom...i want a fast rom, but with some options to allow me more greater control over the phone.
Also, i know this is a bit off-topic, but can you recommend me a widget app, where i can quickly dial phone numbers i.e. by touching a person's photo?
Hi I was searching for roms to change stock and so i found this two

Which one its better for my i777?
Also i have root sotck but i dont have cwm how can i install it?(I know this is in the stickies but i dont know so much about kernels what should i install)
In case that cmd10 its better where i can download the gapps?
Also when im done installing the rom can a install this kernel with the 2 roms or it is not compatible?

I'd recommend that you pick your custom firmware from the xda developers SGH-I777 Android Development or Ported Development forums. Look for one that is currently supported by the developer, if possible. This phone is getting a little older and some of the developers have moved on to other phones.
You can use Mobile Odin lite or Mobile Odin pro to install a custom kernel. You should choose a custom kernel that matches your version of stock. What's on the phone now?
Thanks for the quick answer

I can easily second this. I average about 13 hrs with less than half of that in screen on time. With medium usage my battery lasts almost 24 hrs.

With this official stock, you should use AJK v4.9 NoSwap to get CWM recovery so you can flash the firmware of your choice.
I've only been using SHOstock3 since forever, so I can't make any comment about the other firmware you mentioned. As I said before, it's best to choose a firmware that is still supported by the developer. SHOstock3 is, and several others are as well. Look in the development forum for threads that are active, then read the threads to see what's going on with them, and how users like them, etc.

You said the phone is already rooted. The answer is in post #2...
Install Mobile Odin Lite from here, or Mobile Odin Pro from the play store, on your phone. Download the zip file from the AJK thread, open it and extract the boot.img. Transfer the boot.img to your phone via usb or whatever file transfer you use. Then use Mobile Odin to install the kernel. Now you have CWM recovery so you can flash the firmware of your choice. Flashing the kernel this way does not flash the key layout, so see this post if you intend to keep stock for a while.
I'm in the same boat
I'm rooted and running stock att 4.1.2 and have been searching for advice like this...many thanks CnC.
I've never flashed anything (kernal/rom/modem/etc), but I know that I need to start by getting a modified kernal that has CWM recovery to do pretty much any system mods to my i777.
My 1st question has been, which kernal? AJK, Jeboo, others? Again thanks for a recommendation CnC.
Does flashing a new kernal delete any system/user/app data? That is my second question. If so, what method should be utilized to back up, other than storing data on another storage device.
Thanks again to the OP for asking a question that I've had, and for the other contributors for chiming in!!!

You can flash the AJK kernel with Mobile Odin without needing to wipe data. Your system and installed applications will not be affected.
However, when you decide to flash a custom firmware, you will need to perform a wipe data/factory reset. You should always do this when changing base. You can use Titanium Backup to retain installed applications and their data, but never install any system data with TiBu. Titanium Backup is something people who customize their phones use almost universally. If you plan to flash firmware frequently, you should pay for the Pro version so that you can have batch restore, and some other nice features.

Hmm, just curious, but I don't see an option in TiBu to backup apps and their data (not system data).

Then you're not looking in the right place: Under batch operations (little square icon at the top right with a check mark), Backup, backup user apps.
It's there in both the paid and free version.

That only backs up the app, not the data and the app, IIRC.
Best thing to do is to try all until you find one you like. If you're like me you'll love all of them.

I would think twice about either leaving it stock or getting the power button fixed, because if you mess up and need to get into recovery or download mode(bootloop for example), you are going to have a **** of a time. At least get yourself a usb jig and also familiarize yourself with using adb. Anyways...
First you'll need to flash the modified philz kernel from HERE to get root access. Read carefully, especially the second and third posts. You will have to match the kernel to the stock rom version you are using. Depending on which custom rom you want to install, you'll probably need to then flash a newer recovery, but take your time and read up as much as you can on the steps to take in flashing etc from the OP's and other threads and you should be ok. Follow each step to the letter, as you don't want to mess anything up with no power button!!

Yes there is, but not a standalone zip. You need to flash a kernel that has twrp like apolo or gustavo kernel.

Gustavos doesn't work, only works on later android. I'm not 100% sure apolo will work on stock rom either, it might. It definately works on custom touchwiz 4.1.2 roms such as neatrom(from 4.x branch). The philz kernel from the link I posted earlier(XWLS8) has touch ui if that is your main need. Only it would need to be updated if you were to try flashing a 4.4 or 5.x rom later though.
Apolo thread
Apolo works on stock 4.1.2. You need apolo v4.15b
Even if everything goes ok, the OP might still end up with a boot loop......In which case he's still gonna need all the buttons to boot into recovery to wipe data........
I've lost count of the number of times I've advised getting hardware repaired BEFORE flashing stuff......I owned the S2 and flashed it to within an inch of it's life, but I wouldn't have even considered flashing with broken buttons........
Get it repaired, it really will stop you facing problems.......
