[Q] Quick question regarding ROM and Kernel backups - Galaxy S II Q&A, Help & Troubleshooting

Hi,
I've been searching over the forums for the past few days and i've been thinking of rooting my Samsung Galaxy S2 and i've got a few questions, yes i've been searching around for them and I still find i'm confused, if there is a logical answer somewhere else in the forums I apologize but i've not been able to find the answer.
1.
Chainfire's rooting methods seems to be the easiest methods to do so for the
Samsung Galaxy S II I9100
I'm worried that if the phone I recieve tomorow is the i9103 model it won't work. Wondering if someone can confirm this for me.
2.
Custom ROM's and custom kernels compliment each other and I can't wait to load them onto my phone when I finally recieve it.
But is there a way to backup the original ROM and Kernel that I recieve just incase there are hardware faults with my device and I need to hand it in with the warranty i'll have to load the original ROM and original Kernel somehow?
Is this possible?
3.
Will the USB jig as shown in a thread on this forum work specifically for the i9100 device or will it also run for the i91003 device.
Sorry if I sound a bit paranoid but I'm just worried about my warranty, but at the same time I wish to use the EPIC creations on this forum. Hopefully you guys can help me. Thanks

Dont know what a 19103 is .

Yes if you have a backup of the rom or have a copy from the branded rom post in dev section .
#Failing that a flash of stock Samsung rom will remove root .

If you have taken the steps to backup your original firmware and know how to remove root etc then you are starting from the beginning as opposed to many who try to find those answers afterwards .
Also check out the backup your EFS thread and or Nitrality app in the market to back up the IMEI via EFS folder in dev section .

Reverting to stock after flashing CM10 on AT&T Galaxy S III?

Hi,
I am considering flashing CM10 to an AT&T S3. There is a post on an Android blog which states the following regarding flashing CM10:
Create a NANDroid backup to backup your current ROM. In case there is something that doesn’t work out with this ROM, you can always revert to your old ROM.
Click to expand...
Click to collapse
If I create this NANDroid backup with clockworkmod, can I simply restore back to it after flashing CM10 to revert to stock? No other steps other than selecting backup/restore in clockworkmod?
I was running CM7 on an Atrix 4G and had created a NANDroid backup but later learned that to restore stock I would need to either flash a fruitcake from the house of pudding or flash the riskier SBF, or something like that. I never tried because I never felt comfortable enough with the processes.
Now I am just wondering if the revert-to-stock process for AT&T S3 from CM10 would be the same. If there is a revert guide please point me to it. I've found comprehensive CM10 flashing guides but not revert ones.
Thanks!
I'm about to go out to dinner and don't have time to explain this, but you should really google the different regional versions of the GS3 before asking advice on flashing your AT&T version.

I have Googled and Google, both before posting and after. Perhaps my Web searching skills are horrible.
Regardless, I have not found someone who has switched between CM10 and stock on an AT&T S3 or a tutorial detailing the steps to revert. Until I find some more info I am hesitant to flash.

I think what the poster was asking is do you have an International SGS3 I9300 or some other phone . Firmware from I9300 may brick non I9300 devices .
You mention AT &T S3 = not this forum phone ????
Many users mistakenly do such that is why we have a sticky .

i dont know what happened, but oh well...i rebooted the phone, its in usb debugging and all that..

Just simply click yes, it should work or check the extension of the files. There are some picture extensions that the phones don't recognise.
qbking77 method
As their is no such method i believe on this forum .
But you could post a link to check for this root .
My big guess is that you are yet another in the wrong forum and do not have International I9300 phone .
If so firmware from here may brick your phone be warned .
Of course you may well have a I9300 but rooted with a method that is not for the phone .
So what phone have you and if its I9300 check the root method .

never had an issue till now. the phone is rooted, i have the superuser

Lets make it simple you have L710 not a phone called the I9300.
This is not the Sprint L710 forum we know nothing about such a phone you would be better off in the Sprint L710 forum .
Does that make sense you are in the wrong forum as i keep saying .

[Q] No service after installing any new rom?

Hello guys, I am kinda experienced with flashing roms and stuff since I owned galaxy s2 for over a year. However I bought a second hand galaxy S3 one month ago and it has a turkish firmware however when I tried and installed a new rom everything seems to work find except the network service all i see is a circle and has no service and i tried many roms even jelly bean rom (which worked fine with my friend's S3) even i installed the same exact firmware that i had when i got the phone with the same kernel but got nothing :/ then i took it to where i bought it and he told me i can not install any rom on it and just the one i had on it then he took it for like an hour and it was working again... but its really bothering me! what's wrong? i want to install jelly bean or cyanogenmod but afraid to lose the service again i read its something related to radio or stuff? so any help please?? and here is a screenshot of my kernel and rom..
I think you might want to flash different modems and see what works best for you

One search before posting and read the faqs and guides before not after flashing .
Two it requires you to restore your backed up EFS as per the faqs and guides .
Not read the faqs and guides and no backed up EFS then you require a service centre .
#But you can try a factory reset and flash stock rom first .

[Q] am trying to understand s3

hey i'm reading guides in http://forum.xda-developers.com/showthread.php?t=2344125 to understand s3 more
but i have a question about mine ( sorry for being rushing in but i do need to change my phone these days )
my s3 is on leaked 4.2.2 israel , i need to flash back into 4.1.2 stock EGYPT ( or any good custome ROM ).
when i flashed 4.1.2 EGY before it made " restarting bootloader ". so rootSU told me to make factory wipe.but it didnt work
while am reading i found that restarting bootloader is a good sign that my phone isn't brick ( note : its working normally but the leaked ROM 4.2.2 having alot of issues ).
what should i do , please ask me for what u exactly need to know of info about my phone so i can provide and fix this.
(( do i need to just wait for 4.3 official release )) ?
thanks in advance

efs is not related to rooting or custom roms mate. it is related to the network connection and your imei number. you need to back it up and keep safe so that if you face network problem after updating the phone to the latest 4.1.2, that might help you restore. refer to the thread under my signature for any queries relating to efs/imei.

[Q] Rooting SIII clearification

Dear everyone,
i am getting in the next days the samsung galaxy s3 and i would like to prepare myself about what i should do to root the phone (and save the EFS folder).
I had from a colleague a samsung galaxy s2 which lost the IMEI and EFS folder, that's why i know that is crucial to save all. Plus i excercised on it to root the phone.
On the SG S2 i routed the phone loading the "philz-touch_3.00_i9100-signed.zip" with the phone and then applying the "Root_SuperSU.0.98-Busybox.1.20.2-signed.zip".
Phone was magically simple rooted and as simple as that, could be again unrooted.
Now, I am checking what to do for the samsung galaxy s3, but it seems that the procedure is not so simple and riskless anymore.
I read almost everywhere that the procedure is the one found on this website http://techverse.net/root-samsung-galaxy-s3-android-4-3-jellybean/
The procedure descripted asks me to use odin and from my experience with SG S2, this is there for reflashing the phone, or better to put a new rom in it. So if i did not understand wrong, with that procedure i basically put a new rom that is rooted. Am i right?
this is not really a good solution for me, as the unroot would not work good anymore.
Searching then deeper in the xda forum, i find this: http://forum.xda-developers.com/galaxy-s3/orig-development/i93xx-philz-touch-t2002953
So this seems to be much more similar to the one i applied to my sg s2.
Now the question is, why if this is much more simple, is so less shown as a solution and result on google?
is that "philz_touch_xxx.zip" + "Root_SuperSU.0.98.Only-signed.zip" for rooting the SG S3 as easy as with the S2?
Sorry if this question might have been already posted and answered. i just could not find it in the forum.
Thank you in advance for your attention!

So you mean that can be easily rooted with the files "philz_touch_xxx.zip" + "Root_SuperSU.0.98.Only-signed.zip" ?
does it flash a new rom somehow or just makes the device rooted?

ok so basically i just have to press volume up, home, power on button, open the CMW in the sd ("philz_touch_xxx.zip"), then from there apply the zip file "Root_SuperSU.0.98.Only-signed.zip".
correct?
sorry that i ask over and over, but i cannot brick this phone
You can't install philz recovery from the stock recovery, you would need to flash the .tar version with odin -so you would be better to use CF autoroot as recommended in the sticky guides.

isn't there any way to root the phone keeping the original rom?

WOW thank you so much! I read it and now i have much clearer ideas.
SO: i will just root installing a custom recovery, but no room. perfect and clear like water.
Now i have a question that might have been answered in those threads but i just did not see it (or i would not ask i promise):
If i let the samsung galaxy S3 android upgrade to the latest android version through the official tool KIES, and THEN i make the root, so i have the latest android version, is it possible? If yes, can i use the same tools indicated in http://forum.xda-developers.com/galaxy-s3/general/ref-understanding-basics-rooting-s3-gt-t2362743 ?
Thank you for the links!

AWESOME!! so that means also that if would ever come out any future android upgrade, in order to upgrade officially i should unroot the device, restore the stock recovery, update via kies and then re-root again. I think i got the whole thing!!
---
I was checking on the samsung galaxy S2 (previous phone) the CMW installed. There, in backup and restore, there is "backup" "restore" "delete"....
is that backup the NANDROID backup? if so, why isn't that clear like idiot prove (like me ) ?
Okay. Flash cf auto root in odin. Just go download mode on ur fone, then connect it to the pc. Then just flash the cfautoroot file in odin. No nid for cwm. Flash cwm AFTER u flash cfautoroot in odin.

ok you wrote really nice, but i don't understand what i should do after connecting it to the pc. You wrote "then just flash the cfautoroot file in odin", but isn't it what you wrote me at the beginning?
Instead of asking people to write out exactly what you want to do, just go and follow the guide -they are provided for that reason to help new users safely root etc.
