no it will not soft brick ur phone ma8, need not worry
u can install RR JB v3.1.2, just fallow the install instruction in the OP of the rom thread and also read some extended steps of installing the Rom in the general FAQ of that rom thread main post

Do I need to unlock bootloader?

No you don't, just follow the instructions in the rom thread. It's simple as that

Well you heard wrong. There is no such thing as a "soft" or "hard" brick, Those are just terms n00bs like to use as they cant distinguish the difference between bricked and not bricked, all they see is rom not booting and think "**** me bricked me phone, better panic immediately post topic without searching".
Your device is only "bricked" when you cant access/use download or recovery mode which can happen when you corrupt bootloader, use faulty kernel and wipe device etc. In these cases your only option is using JTAG fix or mobo replacement.

[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.

Galaxy S2 GT-I9100(G)!!Cynogen Mod Help!!!

Ok. Here is it. I have seen a stable build of Galaxy S2 GT-I9100G, REMEMBER IS (G)!!!! Don't reply me with the answer of S2 without the G, I'm asking the[G] Version. So the stable build was here http://download.cyanogenmod.com/?device=i9100g&type=stable for the [Direct Download: cm-9.1.0-i9100g.zip ] So i wondering if it really stable and safe. So, here the Question.
1ST:Is it safe to flash? Will it brick? Worth it? And what Android version IS IT?
2ND:Is this CWM Good, Working, and Safe to flash?So, i'm giving 2 link, (Not downloaded from here)=http://forum.xda-developers.com/showthread.php?t=1631934( and i found these word=This is a kernel including ClockworkMod Recovery for use on Samsung roms.
Don't use this kernel on aosp based roms like CyanogenMod!!!) And this link is where i'm downloaded the CWM and flashed it, http://forum.xda-developers.com/showthread.php?t=1683800( because of GT-I9100G_LP7_ClockworkMod-Recovery_5.5.0.4 it make me think it is the same from the first link i gave that have LP7 hacked, and i wonder it will it be also not support cynogenmod.
3RD: If the CWM at STEP 2 is not supported, What CWM that is work for SAMSUNG GALAXY S2 GT-I9100G and Flash able to cynogenmod with not PROBLEM!
4ST: Anyone have this on their Galaxy S2 GT-I9100G? Is everything WORKING FINE? Is the Performance and Battery Good?
5ST: Do i need to factory reset the phone before and after? And can anyone tell me the step if you can?
My phone is rooted and my battery is so bad :crying:and i wonder is this rom good for battery and performance. I'm afraid of bricking my phone because of the CWM. I installed cwm on galaxy 5 and it died.:crying: So This is important information to me. and PLEASE ANSWER ALL MY QUESTION CAREFULLY!
First of all... You posted at the General Forum (which is wrong actually)... You should probably post at the Q&A Forum... Devs here will probably burn you for being demanding so much while showing excessive 'noobidity'

Alright, ill post this is Q&A forum that you said.
1. Yes, it is safe. And CM9 is Android 4.0.4
2. If you want CWM I suggest you to flash Horsepower kernel
3. CWM5/6
4. AFAIK, everything works
5. Only before changing the ROM.
hmm

How do i get back to original rom

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?
Thanks once again

For official stock rom, check

And search latest stock rom for your region.
If you like custom rom, then there are so many roms on xda. I like omega and alliance roms. Choice varies from person to person

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.

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?

Question about superbrick and upgrading to Cyanogen!

Hey everyone,
Sorry if the Answer was staring me in my face but I'm not sure about upgrading to the CyanogenMod because of the superbricking I might get..
If any help can be given as to whether I am safe to do it, it will be much appreciated, My android version is 4.0.4, Build number imm76D.XWLPT.
I have just rooted it with XWLPW-ROOT-CWM6, and It seems to have rooted fine.
Will be much appreciated if I can get any help as to whether I can Flash it with CyanogenMod and everything will be fine..
Thanks again
EDIT: Yeah I just realized about having the Superbrick bug, I must have a kernel that is not liable to bricking, I rooted it with PhilZ touch 3 and when I go into recovery mode it says CWM Base version: 6.0.1.8 at the bottom, Am I safe from the bug?
You're safe as long as you don't perform a wipe from stock recovery in 4.0.4 (and not all phones have an insane chip). So yes, you can flash CM.

EDIT: Sorry, do you know which CyanogenMod I should flash? I just want to upgrade to one that is fully working, but there are many in the index and I dont know which one to flash :s THANKS!!
and If I dont do a wipe? wont it be stuck at boot as the Guide says it will?
I highly recommend you read the discussion thread for the version of CM you're wanting to try in General section. So you can get a handle on other people's experiences with it, bugs/flaws/annoyances/features/etc. I never flash a rom without reading the first 10 pages of those threads & the last two weeks or so worth of posts so I know what I'm in for.
I agree. And you always have to perform a full wipe if you change firmware.

yes thank you I will, but do I wipe my phone before I install CM? or..? during it..? I'm scared of this superbricking ^-^, I have flashed my GS1 before with no problems, but problems arose and I've been out of the game for a while, and have forgotten phones and roms etc for quite a bit ^-^

I assume you've read guides about how to flash a rom? Copy the zip-file to your phone, back up, wipe and flash.
You don't have to be scared of this superbrick bug because you're already running a custom kernel.

Well, I was trying to root my phone so I don't think so, now that I think of it no, its only root and clockwork recovery mode thingymajig because file size only 7mb so if it was only root, my build number and everything is as same as before ^-^,
That's what I am so confuzzled about, I need to downgrade to a custom rom that must come with a custom kernel right to be able to upgrade to cyanogen right...? otherwise ill brick it?
No. Make sure you flash a custom kernel (for example Siyah) with Odin. Then there's no need to flash other firmware first before upgrading. Just wipe your device in CWM (after the back up), and flash the rom you want.

Thanks, thing is a lot of things are outdated like the guides, do you know if I can use the latest odin which is out that apparently is for the S3? I've spent two days trying to do research on this and im failing quite badly :'(

Make sure you have kies installed or at least the drivers.
Reboot into download mode
Run ODIN 1.85
Flash Siyah kernel (.tar) via PDA section
Boot into recovery run backup
Wipe data/factory reset
Flash CM zip file.

Btw, if you have any apps/appdata you need to restore after wipe you can restore them from your nandroid backup using appextractor.
