( and stock rom= original rom )?
NO stock in both cases means Samsung rom/kernel .
Original may be modified /branded by the network/vendor .
2-why for change stock with insecure stock ( for root) in odin we should checked F. Reset Time ? can we dont tick it to doesnt reset phone?
Follow instructions is the method >> But ODIN always opens with that box ticked unless user unticks .
3-when we use insecure kernel and root and install original kernel ( too hide yellow triangle) can samsung kies say me my phone has new firmware? or after root kies cant recognition new firmware for my phone?
You no longer have matching codes .
4-how can i back up my kernel ?
CWM from rooted phone backup rom . You can then extract the kernel if required . ( kernel is only a part of the firmware and is not the full firmware )
Pointless backing up a kernel backup firmware includes kernel
5-after install new rom should we reset factory
YES/No really depends upon instructions with that rom .

REALLY thank u JJE i get happy i find a person that answer me and if i have a question im not alone!
in Q3 i asked can kies recongnice new rom for rooted phone ? or not.. but i cant get mean of ur answer

Answer is either yes it will or no it will not.
Depends upon what you install as a custom non standard rom .
KIES updates original roms thats its job >>> other roms stock roms it may or it may not update . No update you use ODIN as usual .
KIES supplies firmware but you may have a long wait for the most uptodate firmware for your phone .
Via XDA and ODIN we have firmware before it is sent to Kies .

and some question again
1-do i need root again after update rom? (original rom)
2-does update rom (sam's rom) delete apps and messages and totally all thing?

[Q] Rooted without making a note of my original version

I recently shifted to an android from an iphone and I am loving the experience. Unfortunately the noob I am, I didnt do my research properly and I went ahead and rooted my Samsung Galaxy S2 without making a note of which version my phone was (i.e KE1, KG3 etc etc). Now I want to shift back from Lightning ROM to the original Samsung Sense but I dont know how as I dont know which rom or kernel to download. Could you help me out. I dont have a clue of what needs to be done. Also what do I need to do to un-root my device if I ever require to do so in future.
I would be grateful and in debt to you if you could help me out.
Samsung dont have Sense .
Product code on the box or under the battery may give an indication of original firmware otherwise its guesswork .
Question was phone branded was phone from a particular area .
Stock rom post has many Samsung roms Branded rom post likewise .

[Q] ROM

Hi,
Can anybody tell me if i root my s2 (currently on KF3 firmware) with cf method and flash stock kernel,will i be able to install new ROMS like litening etc,how ?, and will i be able to come back to my stock firmware and kernel,and how ?
thanks in advance !
You can flash any Custom firmware anytime, without root. And you can go back to Stock firmware and kernel anytime.
Regards.
so if i root(by a method you earlier told me),can i also use any rom on that ?if yes then how and also can you please tell me how to come back to stock rom(before flashing with custom rom) state ?
You just need to add the .tar file of the Custom firmware in PDA section of Odin and flash, same for Stock ROM.
Regards.
you can root your phone as ihappy said but use the threads on the forums to find the stock kernels and roms that suit you. and i mean by what region you at. most of the custom roms come with root anyway so i would not worry about rooting. the thing is though whenever you do flash always make backup. first time i flashed i did not do backup and i was panicking on how to go back to stock.but thankfully the guys in this community are the best around and helped me out. hope my post helped in anyway

How to flash Chinese I9100G ??

Hi,
I am sorry for the newbie question.
I just bought a Galaxy S2 GT-9100G here in China.
Only after buying did I realise it is a 'G' model. damn.
anyway - I would like to 'reformat' the device, and place an Israeli ROM on it.
I hope I am using the correct terms.
The reason for this - is that the chinese version comes without Android Market,
and other stuff (and the Israeli one does).
1. Do I need to root the device first before I can change the ROM ?
2. If so - I have seen in this link
http://forum.xda-developers.com/showthread.php?p=18099806
that flashing the kernel is the only way to root the device.
I have flashed my brother's Galaxy S2 (I9100) a month ago, using the steps shown here:
http://samsunggalaxys2review.org/root-your-samsung-galaxy-s2-heres-how/
(used OdinDownloader and SuperOneClick). Do I do the same with this device ?
Which file do I supply to Odin ??
3. Is there anyway to flash the Israeli ROM on this device ?
or it won't work, cause Israeli ROM is only for I9100 and my device is I9100G ?
If not - what can I do in order to flash a new ROM with built-in Android Market ?
Thanks to everyone who can help !!!
If u flash the new rom to your phone, it no need to root!
I own a I9100T, I flash it to I9100, it work fine, so I think u can flash it to an Israeli ROM.
Check this thread: http://forum.xda-developers.com/showthread.php?t=1192575
In general, be careful about flashing the China phones. It seems they went out of their way to make sure those phones comply with China's government restrictions.
i9100G got KH4 and KI1 rom, u need to donload insecure kernel to root them

How do I root ?
Just use Odin or do I need SuperOneClick also ?

So, ghmail, are you saying you have managed to do so yourself ?
Change the ROM on an I9100G to any ROM you want ?
On the topic - how can I backup everything on my device ?
I mean - the bootloader, the ROM and all the other stuff I might mess up if I brick my phone ...
Please remember..u cant flash any I9100 custom rom because its diff between I9100 and I9100G..If u flash it the phone will be semi bricked and u need to flash back to the ori rom of I9100G KH4 or KI1..
China GT-19100G-ZCLC2
Hi People, I am a total novice here. I have been reading your forms for few weeks now, since i Bought this SGS II-I9100G in China [Big Mistake ?? :-( ]
This is my phone :
Model - GT-19100G
Android - V 2.3.6
Baseband - 19100GZCLC2
Kernel - 2.6.35.7 [email protected] #2
Firmware : PDA:LC2 / Phone:LC2 / CSC:LC2 (CHN)
I read thro creezalird pdf user guide and as guessed DooMLoRD_v4_ROOT' dint work with both methods on my phone.
I just want to root the phone so I can install few useful apps, no fancy stuff like flasing or custom rom etc. As you know even google play is blocked. Can someone point me to right link/guide me to do it.
I did read many articles (too many of your forum's) and probably why Im now totally confused. Reason is I do not see anything pointing to ZCLC2. Maybe I am not looking hard enough.
I got it done using superatom's kernel. Now all sw works on chinese phone.

[Q] ICS Update - SGS 2 Rooted 6 months ago

Thanks for reading - I'm a noob.
I came here to learn about rooting devices over 6 months ago and decided to have a go at rooting my SGS 2 to remove the bloatware and speed it up a bit.
Performance has been great - I left the stock firmware because the OS/ROM was not a concern to me. I simply flashed the kernel with CF Root: CF-Root-SGS2_ZS_OZS_KF4-v4.0-CWM4.tar
Now I am led to understand I would need to flash back to my stock kernel to allow the OTA update for ICS - the only issue is I cannot find any available downloads for I9100TDVKF4 - Telstra's stock kernel.
Now I read somewhere a reply to a similar question was "just flash it with a new rom, I dont know why you want to go to stock" - Well I want to update to the official ICS. I was under the impression that would be available a long time ago and never was. I just want to....
Please can anyone help me to point out where I can find that kernel? perhaps there is a different kernel i could use?!
Is there any ICS firmware I would be able to download and flash to the ROM using Odin whilst keeping my phone rooted?
I found this place really helpful in how to root and now I just hope someone can help me get onto ICS!
Cheers
Is there any ICS firmware I would be able to download and flash to the ROM using Odin whilst keeping my phone rooted?
No only custom rooted firmware .
Try Checkfus for your stock firmware download and flash via Odin .
Dont confuse yourself with kernels without understanding .
ICS on Checkfus or Kies for your phone install otherwise wait until your provider releases .
or flash your original saved firmware that will overwrite root .
jje
Thanks for taking the time to reply mate....
Dont confuse yourself with kernels without understanding - dont worry ive been trying not to but it seems thats the only thing i changed on my phone when i rooted it so i was lead to believe i needed to change that back...
My provider has just released new version of ICS but i cant actually install it once ive downloaded it over the air it only gets to 8% then reboots itself and i believe thats because the phone is rooted...
or flash your original saved firmware that will overwrite root - I dont know if i backed it up correctly on the guide i was using!!! The only thing i backed up was the apps using titanium backup so now i feel im stuck!
Use check fus down loader and get the official ics ROM.
It's under i9100t Australia/telestra
Problem solved.

Start with a ROM of your choice, just pick one you'd like to try and test it out. If you don't like it try another one out.
*Repeat untill your phone dies

Hi Vinay, Post ur questions in Q & A forum. Ok the difference between custom and official ROM is u ll get ROOT access, many mod from official. Moreover check the caution lines before flashing any ROM.. Watch some videos on flashing ROMs. Also always a copy of main original official ROM..
and a nandroid backup would be also useful just in case something goes wrong
Hi!
Custom rom made by developers that can be from stock (samsung) basis or aosp/aokp (google) basis according to what the devs wants and need, so you need to know about what features and themes are included in the rom so that it would match your preferences. There's sure are a lotta rom out there to try. Be sure to flash only rom that made for your phone and made a backup just in case..
Happy flashing!

Hi to all and thank you for helping me.
The big trouble is that i led my phone in to strange state where only triangle appears and logo of samgung and gets stuck in that state ;after downloading some wrong ROM, my mobile got to this state , now i want to get back in order to wakeup my mobile and brings it too original state as pervious , also to inform you that the mobile was locked to local operator and i tried to unblock and i did mistake .
I just want to have brief guide to how to start as there are many information in this forum and i dont know which tutorial should i base ON.
Basically i just want to know which ROM should i take and procedures in order to install the correct ROM in correct way. I allready has the ODIN installed in my PC and at the moment i can navegate in my phone by Clockworkmode but i dont know what i should do after that , i do know that i can put the ROM in SD Card and try to force the mobile but first i would like to have exprties opinion on this matter, PLEASE.
Regards
Vinay
Well basically if you want to restore to original state, you have to flash the stock rom for your phone or the backup you made before (which I assume you didn't made it). Try to find the stock firmware/rom for your phone version/country/region on sammobile and flash it using odin (put your phone to download mode first). Hope it helps..
P.s: don't worry about the yellow triangle thing, it'll disappear after you flashed the stock..

Thank you sir and thank you all moderator helping me on this ,
Ok ;i understood but if i dont want to go back or lets say if i want to root and unblock without original stock ROM what procedure should i do , please.
I am also having difficulties finding the best ROMS for mobile S2 GALAXY where i should find them , please.
Best Regards
Vinay Navinchandra
Dont mention "best rom" since its against the rules.Youll get a warning and your/this thread locked.
Yeah, it's a matter of preferences if you talked about what best so browsing around and try for yourself..
Some custom rom got pre-rooted, and some need to be rooted first or even not at all. There's lotta method to root sgs2 and it's not hard at all, just google it and you'll get it..
