[Q] Rooted Phone...now how do i install custom ROM - Galaxy S II Q&A, Help & Troubleshooting

Ok...Yep im a newbie and yep ive looked in the forums but im getting confused..
Phone :Samsung Galaxy s2 i9100 running 4,0.4 kernal version XWLPT.
Ive rooted the phone using the method 1 on this guide.. http://forum.xda-developers.com/showthread.php?t=1746794
Now im looking to install cyanogenmod but i dont want a bricked phone so was wondering if anyone cleverer then me can give me a quick guide of how to install as all of the guides are getting confusing lol
Cheers for you help in advance...

Now that you have rooted your phone, you can install CWM. CWM (short for ClockworkMod) is a custom recovery menu which allows you to install any custom ROM packaged as a zip file. Refer to part 2 in the tutorial you followed to install CWM. I'd also flash another kernel such as Siyah (thanks to gokhanmoral) to make sure you can't brick your phone. That stock kernel you have is dangerous and you must get rid of it before doing the data wipe required to install CM.
Once you've done that, grab a CyanogenMod build and install it from the CWM recovery. You should of course place the zip file on your internal storage first. Make sure to follow the instructions here.
By the way, there's a "Q&A" section for this device, so please try to ask your questions there, they should get answered faster and by more people if you do that.

Cheers tydem..i thought the kernel in mine was prone to bricking...ill flash the one that you recommeded and see how it goes

just to add to that.. do we have to update Modems as well? can we update them?

No.
Yes.

[Q] Please Need Advise Before I Install CM9

Hi I want to install latest CM9 nightly, As Im installing first time, I just want to make sure that my phone is running firmware lower than XXLPH though it looks lower but cant judge, I went through official CM9 Thread I can follow all the steps except this one. And also I have already rooted my device using
GT-I9100_THR_I9100JPKJ2_I9100OJPKJ1_I9100XXKI4 (firmware) and
CF-Root-SGS2_XW_XEF_KJ2-v4.4-CWM4.tar (root kernel)
I still havent installed any custom rom yet.
Here is my current phone details:
GT-19100
Android 2.3.5 (STOCK)
Baseband 19100XXKI4
Kernel 2.6.35.7-I9100XWKJ2-CL676699root
____________________________________________
I thought my firmware is higher than XXLPH so I found this guide to ugrade to ice cream firmware first:
http://androidbeast.com/937/tutoria...oid-ice-cream-firmware-on-galaxy-s2-gt-i9100/
then root it with this kernel :
http://androidbeast.com/948/root-samsung-galaxy-s2-cf-root-kernel-odin/
Now I need your advice that weather should I continue following above guide or should I start flashing CM9 firmware staright away ??
now that you are rooted and on ics, you can then follow the instructions in CM9 thread.
Flash odin version first and then update to latest build from cwm recovery
codeworkx said:
If you're a bloody noob and getting confused by following simple instructions, go down and read about using the noob-proof ODIN method.
First time installing CyanogenMod 9 to your Galaxy S II, or coming from another ROM:
- READ FAQs: http://teamhacksung.org/wiki/index.php/Experimental:GT-I9100:Frequently_Asked_Questions
- Make sure you're running ICS bootloaders lower than LPH: Download (flash as PDA with odin or extract and $ sudo heimdall flash --primary-boot boot.bin --secondary-boot Sbl.bin)
- make sure you're running a proper working CWM like the one from CM7
- Copy GApps and CM9 ZIPs to your internal SDCard
- Boot into Recovery
- Flash CM9 zip
- Flash GApps zip
- DO A DATA WIPE / FACTORY RESET (otherwise your calendar sync will not work)
- Reboot
- Don't restore Apps using Titanium Backup!
Upgrading from earlier version of CyanogenMod 9:
- Copy CM9 ZIP to your internal SDCard
- Boot into Recovery
- Flash CM9 zip
- Wipe cache partition and dalvik-cache
- Reboot
Using the noob-proof ODIN method:
- Download CM9 Resurrection Edition
- Download GApps and put it onto your internal sdcard
- Open Odin
- Choose cm-9-XXXXXXXX-ODIN-galaxys2.tar.md5 as PDA
- Boot your phone into download mode
- Connect your device via usb to your computer
- Wait till Odin has fully recognized your phone
- Hit the start button and wait till the flash process is finished
- Device boots automatically into recovery
- Flash GApps, wipe cache and dalvik-cache
- Reboot into CM9
- Follow above steps to update CM9 to lastest available version (Upgrading from earlier version of CyanogenMod 9)

Yes, follow the "noob proof" method. (which doesn't seem too noob proof at the moment... :/)
And seriously, why did you start two threads (this current one, and this other one) about flashing an ICS ROM? CM9 is considered an ICS ROM, so really the topic is the same.
Hi.... i recommend this site galaxys2root.com
it helped me figure out a lot of stuff in the beginning. Video walkthrough of installing roms is really a big help.
For the latest Ressurection Remix 1.2 looki the Android developer forum.
I am about to install now
Hope you get it all sorted

Actually on that post I wasn't sure which ROM was based on what firmware but i came to know from users like you and I got clear idea from you all before that in the mean time, i was gathering info through various guides, videos from weeks and merged those ideas in to one then I decided to install CM9 as it looks similar to new galaxy nexus phone and this is exactly what I wanted my phone to look and behave like. Now I am happy and satisfied.
I have done oden with bootloader but in the middle of that the bootloader progress in oden is turn to red and cell get off. now its hard bricked, dead, what i can do

Man... why did you the touch the bootloader first? never play with it unless you know whats gonna happen! and about noob installation guide for CM9 is not clearly noobproof, I completely did all installation with clockworkmod recovery, I used ODIN only once for rooting my phone after that i never used it as I was very very cautious and careful about each and everything bit i was doing.
But never loose hope, you never know what kind of brick you have you have two ways to unbrick your phone,
1.Using USB jig, search it on XDA, Google, Youtube
2.JTAG Service, This is the ultimate solution if your phone is completely Hard bricked but for this you have to send your device to them.
here is their demonstration:
http://www.youtube.com/watch?v=kQdTi2vgMmY
its written in the cm9 installation to do the boot-loader with ODIN, that is what i do
oh bhai....... make sure you had i9100 not the i9100G,
remove battery and see if you can get download mode.
im running cm9 on new bootloader unless intratech still removes them from his stock ROm as he used too..... i came from stock LPS to cm9
that much sense i have dear its s2, and ya its dead, i send the cell to lahore, khi, rwp, but no one have jtag proper equipment

you dont get it i9100G is also S2 and virtually same. you have to see under the batter if its written i9100 or i9100G.
because thats what would happened if you flash i9100 bootloader onto i9100G.
plus faulty usb, dead battery can do the trick aswell.

[Q] What kernel do I need?

I just successfully rooted my phone using the DooMLoRD method. I wan't to use a Jellybean custom rom(probably aokp). What kernel do I need? I have a Galaxy S2 with version 2.3.4 and gingerbread.uckh7.
You need one with cwm baked in. It's that simple. The rom you select will flash the recommended kernel

These are really basic and common questions that you are asking and can be easily found by searching. I'm just giving you a fair warning, because you will be flamed by others for not searching.
Creating backups via CWM is not a requirement to flash anything. It is highly recommended that you do create backups though (especially if you're new to this), in case something goes wrong while flashing stuff.

question regarding root methods

since im new to android i would like to know some information from u guys
From what i have read since now i haven't understood the difference between cf-root and cf-auto-root. Is it possible someone to clarify some basic questions to me?
1) When do we use cf-root and when cf-auto-root?
2) Do they need custom recovery files installed ?
3) Which one is recommended under what circumstances ?
4) I have read something about flash counters. Which one of the two methods messes up with them ?
5) I ve read something about locked boot loaders. Which one is not compatible with them and how can i determine if i have one on a stock non-rooted phone ?
BTW i own a galaxy s3 (GT-i9300 & Android version of 4.1.2)
I know its a lot of questions im throwing here but i would appreciate any help that i could get.
Thank you.

=> If I remember well, the difference is the included/excluded custom recovery, hence if you want a customer recovery use cf-root, if you want to keep your stock one, use cf-auto-root
2) Do they need custom recovery files installed ?

see my asnwers to 1 - 3) above in the quote, for 4 & 5 I am not 100% sure, hence I do not want to give you advice there but the forum got a lot of people that know that stuff for sure
4) both
5) in general, you do not have locked bootloaders in I9300.
additionally, I'd not recommend you to flash anything which does not contain SDS fix. Effectively, as Chainfire abandoned some parts of the project, and as recovery includes kernel - I'd not flash CFrecovery now, but I'd look for something newer.

If i use the cf-auto-root method which does not install a custom recovery file because i want to install the one i want, should i install first the recovery and then the root or the other way round?

cant flash files on CWM

guys im new here on galaxy s2 thread so kindly do not judge me if i ask noob things
i want to flash AOKP for galaxy s2 and i found 2 of them Revolt and thunder roms
download both + dorimanx kernel placed on SD going into CWM trying to flash kernel and rom but im getting this message :
E:signature verification failed !!
Like just about everything else on here, 'E:signature verification failed !!' has been covered many many times on here (Including a couple of times over the past few weeks). Search for those threads, your answer will be in one of them.
i think i have the stock recovery !!
flashing this Cf-root throw odin will give me the CWM ??
Having stock recovery would explain your problem. If you flash the correct CFRoot kernel via Odin, yes, you will have a rooted phone + CWM. However, many people prefer to simply flash the Odin version of a custom kernel (like Siyah) to achieve this aim these days (Given the issues with 4.0.4 stock kernels, which CFRoot is, and the brickbug). Find the relevant Odin flashable version of Siyah for the Android version you're running; check the Siyah threads for which build is compatible with which version of Android (should be on the first page).
all the Cf-root is ICS and im running JB what i can do in that case ??
all i want to access cwm to flash rom and kernel
This recovery I have
Sent from my LT26i using Tapatalk 2
Which as you said is stock recovery. You can flash temporary versions of CWM from stock recovery, but these only persists until the next reboot/aren't permanent. Make life easy for yourself & flash the Odin version of a rooted kernel as advised in my PP (Use CFRoot if you really want to, just don't do a wipe from CWM while you're running it, wait till you're running a custom kernel before doing any wipes).
Edit - You're welcome, BTW.

sorry if i sound noob but frist time im dealing with Samsung its completly diffrent from Sony
thanks for your help
OK. This is my final post to this thread. I tire very quickly of having to repeat myself.
For the last time...Go to the Siyah threads. Work out which Siyah build you need for the Android version you're running. Get the Odin flashable version of that kernel. Reboot into download mode & flash it with Odin.
Done.
Rooted phone + CWM.
dude sorry but i'v found this
flashing this Siyah-s2-v6.0b4
and now i have cwm and flashed thunder rom
thanks for help and sorry for beeing noob here

[Q] Advice needed for rooting GT-I9300

Guys I know this is long but PLEASE don't freak out! I really need some advice from you experts on this! I hope you could spend your time reading everything here and give me some advices! Thanks!
Phone details:
Model number: GT-I9300
Android version: 4.3
Baseband version: I9300DXUGNB1
Build number: JSS15J.I9300XXUGNA5
Hello guys, since I'm not really a rooting expert (previously I rooted a motorola device), I would like to ask for some advices regarding rooting our S3 because I have only one phone and I can't afford to brick it.
1. So basically I'm referring to the guide here. However, that rooting guide is for Samsung Galaxy S3 on I9300XXUGNA7 Android 4.3 Jelly Bean, which is different from my build number (I've checked software update on my device over OTA and Kies3 but it says I have the latest firmware), will it works for my phone? Also in the guide it says to use odin3 v3.09, however in CF_auto_root page here it says to use odin3 v1.85, so which one is working for my device or which one is better?
2. Next I would like to ask is it necessary to install CWM recovery to replace the stock one? After searching around, I found that there are some people who installed CWM recovery even before rooting, is that even possible? So basically to install CMW recovery I think I will follow the steps here, is this working for my device?
3. Okay I know this is the dumbest question... but is there anything else I need to do after the above 2 steps (flashing kernel, modem etc.)?
Thank you very much for spending your time reading my post. I hope you can clear those doubts for me!

Flashing your phone in any way doesn't guarantee not bricking it, see this thread
Scroll down to the quoted section headed Quick Root from there
Download Odin
Download CF-AutoRoot for your phone
Read the link on rooting
It is really straight forward just read up on it but don't read too much into it a frighten yourself

Great that thread helps a lot! I cleared most of my doubts now, but one more question please, after rooting, I wished to install ported apps like S5 launcher and accuweather, and in order to install these I need to flash from recovery. Is it possible to flash this using stock recovery? Or I need to install custom recovery like CMW?
You can't install anything with stock recovery, you'll need a custom recovery.
Make sure you have a full nandroid and efs backup before you flash anything -ported apps can break the framework and produce bootloops.
Seriously though, all this information is available in the sticky or by searching -why do need people to write it all out for you?

Thanks for your information. I did search around and try to understand the things myself, but still there are some doubts remain, that's why I opened this thread hoping that someone can clear the doubts for me. This is my only phone and I really can't afford another (I'm from a low-income family), I just want to make sure everything is alright so that I don't mess up my device. Thanks for your understanding
If this is relevant for Samsung galaxy s3, I got this done the other day using Odin to unlock and root, ran the root app to confirm root. The ROM manager to found CWM recovery flash. So far all good, should take 5 mins in all but an hour in prep and homework.

Don't use rom manager, it can soft brick your phone.
Sent from my GT-I9300 using Tapatalk
Hello! I agree that it would be better NOT to use Rom Manager. Many users had problems because of it. The safest way, in my opinion, is to flash a custom kernel using Odin. For example, I had stock rom and used Odin to flash boeffla kernel (not advertising it, just saying what I did) because that kernel had both a .tar version and a .zip one. I downloaded the .tar version and flashed it with Odin by putting the .tar file in the PDA column. That's for root.
For recovery I'm using PhilZTouch and I love it. It supports both JB and KK roms and that is preety cool. Also it's full touch so I don't need to stress my hardware buttons. It's also available as .tar file so you can flash it with Odin just like the kernel.
That's how I'd recommend anyone to root and install a custom recovery on a Sammy phone because I believe it's the safest way. PS: before launching Odin make sure the phone is NOT connected to the PC and that Kies isn't running in the background (use Task Manager to check) Goodluck! !! :thumbup::thumbup:

Thanks! Will check out PhilZTouch recovery :fingers-crossed:
Currently struggling with deodexing/odexing the stock rom, after reading around I can differentiate between the odex and deodex rom, still digging on how to deodex a rom though (since I want to install some S5 mods). After searching around, it seems like titanium backup can do the deodexing/odexing just nice Gonna do some more preparation, hopefully I can have my device rooted by this week
You could flash PhilZ Recovery and make a nand backup of your rom. This way you'd have an emergency copy if something goes wrong or if you break something in the system. Just my thought
