You can search the threads for guides. I don't use HTC so I'm not familiar with it. Starting you can find a ROM that is suitable for your firmware. Gt i9100G. Be sure not to get GT-i9100 ROM because its two worlds apart. Once you done that, go to cwm and fully wipe everything. Then install from SD card. If the roms has aroma installer you are good to go. To get detailed guides please search the forums.

if u want a custom ICS rom then the same can be flashed with CWM.
but if its a stock ICS firmware then u have to do it with ODIN since the same (stock ICS) cannot be flashed thro CWM

hey bro,
Sorry I couldn't reply your PM.
1. It's very easy to go back to ICS
2. It can be done via CWM recovery but you will need a custom stock based ICS ROM,
Check Android development section, once you find the one you like, let me know.
I'll post the instructions about flashing it.

> need help before i risk flasing my first rom <

This is my first post and i was wondering if people could answer some questions i have.
First off heres my phones specs
Samsung galaxy s2
Model number
GT-I9100
Android version
4.0.3
Baseband version
I9100XXLPQ
Kernel version
3.0.15-I9100XXLPQ-CL223505
[email protected] #3
Build number
IML74K.XXLPQ
I've rooted my phone using rachmat3 method and thats how far i've got because only just got phone as a gift and im scared to flash a new rom incase i brick my phone.
Is it safe to use the cwm.zip to flash a rom that i used from rachmat3 root method or do i need a updated version of cwm?
Can someone recommend a fully working paranoid android rom that i can use for daily use?
Which kernel would be best to use with paranoid android rom?
Should i flash a kernel before i flash a rom?
If i install paranoid android rom would i then have a permanant cwm on my device or would i still need to use my temporery cwm.zip?
What is the chances of me bricking my phone?

Flash what ever rom u want till its for GT-I9100
No need to worry
Just read the specific rom instructions carefully
Sent from my GT-I9100 using xda app-developers app
Yes mate now u can flash any Rom ....Just read the instruction before flashing
I would advise you to flash a safe kernel first before doing any wipe and flashing any roms. Siyah is a safe bet.
Sent from my GT-I9100 using Tapatalk 2
1. Download ROM Manager and you'll be able to flash any ROMs you wish using that.
2. All the PA versions are working fine, so just browse through and choose for yourself.
3. Asking questions like that is against forum rules because they often lead to arguments. The best advice is just to download and flash different kernels and stick with which ever one you're happy with.
4. It really doesn't matter in which order you flash them. The result is still the same. I personally always flash the ROM first, but it doesn't make a difference.
5. If you use ROM Manager, as mentioned previously, even if you have to do a full wipe when flashing a different ROM, it doesn't matter because you can simply download it again anyway. Or just save it to your SD card.
6. The changes if bricking your phone are higher if you're worried about it. Just be sure to read all instructions given about installation and follow them perfectly and you'll be fine.
If after reading about flashing ROMs you are still worried, then you're better off waiting for a bit until you've done more research into what exactly is needed.
I'm a product of the system I was born to destroy!
Thanks for your replys.
just follow the steps mentioned and follow some video (like on youtube) and it'll be easy!
Would it be to much to ask if someone could put a link to the right paranoid android rom for my phone please

I don't recommend using ROM Manager since it can brick the phone.
Why don't flash custom kernel and use real CWMR?

Most ROM zips include kernels, so if somebody wants to stay with the same kernel, then it's necessary to flash custom kernel again.

I just mentioned ROM Manager from personal preference to be honest.
I've always used it on my S2 and never had a problem with it.

Just coz i have no pc to revive a bricked phone and i wont beable to check online for solutions as my phone will be bricked.
Sent from my GT-I9100 using Tapatalk
You will need a pc if for example you flash a kernel and somethings not right.You cant get cwm, only download mode.
That happened to me when I flashed a siyah kernel.Phone was stuck and I couldnt boot into cwm.Only way to fix was boot to download mode and use odin/pc.

I can help you from here, pretty simple
Within the next 30 mins, you should be running PA.
First, flash Siyah kernel with your temporary CWM recovery. Very safe

flash siyah kernal via ODIN (or any kernal you like), then you can flash any custom rom you like via CWM recovery. The rom you wanna flash depends on what your looking for.
Ok.

You can flash siyah 4.1.5 from gokhanmoral. Com for galaxy s2
Then you are rooted. You will get CWM 6.0.
Then from recovery take back up of your current stock rom.
And flash any ICS Based custom rom.
Do these steps then in future you want to try JB custom rom then let me know

Some questions regarding root...

Hi all, (this is my first thread)
I wanted to ask a couple of questions about which I am confused...
I am currently running stock 4.1.1 on rooted international galaxy s3..
Q1. Is there anyway I can get 4.1.2 OTA Without unrooting?
Q2. I am not sure whether the country I bought my phone from has got the update yet... So is there anyway I can check that...
P.S I got my phone from dubai..
But I live in India...
Thanks.

Give a try to the temporary unroot option in the superuser app...

Download stock rom through sammobile.com and flash through odin only...

If you already have CWM recovery why not use CWM to flash a custom 4.1.2 rom thats based on Stock firmware (like Android Revolution HD)?
Thats just as easy, has more support, rooted and you'll have future updates faster as well.
I already downloaded omega v34 but didn't flash it because people have lot of issues with it.. Lag, random reboot etc. Stock rom will be more stable I guess..
I haven't tried revolution though...
I'll try it now..
Any other rom you recommend?
Thanks!

I had the same experience, Omega had loads of launcher redraws and sudden lag. No such experience on ARHD with Perseus kernel. That kernel now even has the exynos exploit fixed.
Nope, all other roms i've tried i never used more then a few hours.
Can you give me a link to the ARHD page?

Yeah, everytime you flash the stock image, you'll have to root the phone again... but so what?? I have my mobile sine 8 weeks and i think i flashed it 10times now, and lots of custom-rom installations, configuring the phone etc....
It's not a hard work, you just have to read carefully BEFORE you start rooting, modding or whatever. This forum is awesome and till now i really found an answer to my questions everytime without bothering the ither guys with a question that is already answered a thousand times just have to use the search... so, good luck and have fun with your rooted mobile. By the way, i recommend the Omega-ROM for galaxy S2 and S3, the guys are.doing a great job with their ROMs. If you own a S3 LTE (i9305) i recommend the Pandoriam ROM, works best for me
Best regards

Haha.. Thanks buddy.
Btw, I am not new to rooting, I have flashed at least 15 rom's on my old phone(galaxy ace)
But I was not a member of XDA then.. I just used to read....
But since s3 is much more expensive I wanted to be absolutely clear about the smallest of things...
Because with great power comes great responsibility.

[Q] returning back to complete stock rom

i had rooted my galaxy note 2 (GT N7100). Flashed paranoid android custom rom.
now i have restored my stock rom backup (which i had made before flashing)
but now samsung stock apps like "readers hub", "Game hub" etc. are not working. apps say "Rooting detected" and clos.
and in settings->device status it says "modified".
so according to me the phone is not completely restored to stock rom.
can u help me out? cuz i want complete stock rom.(the original rom i got when i bought the phone.)
Thanks in advance....!!!
Maybe you had first rooted your stock ROM before making a backup. Make sure to flash a new stock image, not a backup you made previously. Look in the Galaxy Note 2 forum for more details.

Search for 'Triangle Away' by Chainfire. I'm not too acquainted with Samsung devices as I've never owned one, so I can't help you with this. But you'll find a lot of guides and everything you need.
