[Q] Get backup after the phone has been rooted? - Galaxy S II Q&A, Help & Troubleshooting

Hi, I think im gonna root my phone. And if i root it and then install custom ROMS and themes. If my phone has a problem and i need to give it back to the store, could i restore it to normal(not rooted) and then give it back to the store?
and if i can, How can i do this?

Yes, before giving it you have to put the Stock firmware back and use an USB Jig (Ebay) to reset the ROM counter. They won't understand if your phone was being rooted or installed with a Custom firmware or any Mods.
Regards.

You can, as long as they don't check the binary flash counter. Your phone counts the times you flashed custom roms. Recovering a backup does not reset this counter.
You need a USB Jig to reset this counter. A home-made usb device you stick into your phone's usb port. I'll make one when I need it, my phone doesn't look like it's about to stop working.

I have one USB at home, but what should i do with it?
What is the stock firmware? and how do you reset the ROM counter with it?

To reset turn phone off .
Connect USB jig phone boots to download mode counter now zero .
Remove jig and reboot .
Stock firmware is the Samsung firmware released to the phone providers for customization,
DEV section Stock Firmware and Branded rom posts .
jje

so if i get a problem with my rootet phone, this is what i do:
1. turn of my phone
2. plug in my empty usb that i have at home
3. then wait
4. then done
is that it?

No
USB jig has two uses ONE to put a phone into download mode where the phone itself will not go to download mode via the Vol Down + Home + PWR keys .
Plus it will reset the binary rom counter to zero .
It has nothing to do with root and will not fix any problems bar the two above .
Dont really know if you understand what has been posted .
One a USB RECOVERY JIG is not an empty usb .

i dont have a JIG , so its not good that i root my phone, right?

Nah nah, you won't root cause you don't have a Jig is meaningless. You just need the Jig to Rest the ROM counter, and that you will do if you need to service your phone. Otherwise it's NO problem.

About USB Jib, URGENT

Really im not new about doing this things about how to flash correctly with odin, etc.. But I really do the things correctly I already flash with stock JFD <-- well that's eclair.. the phone works 100% but i had froyo before I flash to stock so i put the official version firmware that T-Mobile launch.. my phone don't start... in Odin say succesful.. it never turn on,No recovery, No download mode.... Some people say that a USB Jig will turn on the phone?, but i don't think so? why can turn on if the phone don't work the 3 combos?, . Also i read about t mobile block the keymapping or someting like that?.. I should be able to have my cellphone in download mode with a usb jig? i will buy it if someone tell me if I have a little hope with my phone..
Please help! ...
the phone seem dead.. like a toy ..
I called in my country a place specialized on cellphone repair and say something that if the phone don't turn on they cant repair it because the MOTHERBOARD is dead ( broken ) idk.
Before purchasing a JIG to get into Download Mode try this...
Make sure you have ODIN OPEN with admin privileges!
1.) Take off your back cover, remove your sim & mirco sd card.
2.) Remove your battery.
Make sure you have the USB plugged into your PC but NOT your phone!
3.) Hold the volume buttons.
4.) Put the battery in.
5.) Put the USB in.
You don't necessarily need the download mode image to be present. As long as you are getting the COM ID to light up yellow in ODIN, just flash back to stock like normal.

Unrooted my sg2 I think?

Hello , I rooted my s II a while ago but I wanted my warrenty back so I wanted to unroot but I didn't have to usb Jig.
But , today I updated my firmware on kies and root checker says my root is gone so does that mean the counter is reset ? and also how do I check the counter?
Sorry for such nooby questions but well I got to start somewhere.
A USB jig is currently the only way to reset the counter. You can confirm that it is still > 0 by booting into download mode (vol down+home+power).

[Q] doubts restoring, unbrick procedures sg2

Ok before something goes wrong and start become crazy asking for help to fix my sgs2, i have read the necessary info (i guess) to do it by myself , I have this backup files
1- Nand backup (when i first rooted, i made this in CWM, CF-Root CWM5)
2- Stock rom/firmware 1 file (from sammobile.com exact the same carrier PDA,CSC,Modem)
3- EFS backup 2 files (with HC-kTool, i dont know in which case use it)
So in the case i install "x" numbers of roms and kernels or if i brick the phone and want to go back to its brand new state or recover the phone, which is the best procedure? Obviously depends on the symptoms but, are this the options i have in base of my backup files???? :
1-Go in to CWM and use Odin to flash the stock Rom
2-Go in to Recovery mode and use the nand backup
3-Use a jig to go to CWM and use Odin to flash the stock Rom
I get a little confuse with the backups files i have, because nobody seems to use the nand backup, also i have read
[GUIDE] Fix an unflashable or soft bricked GSII from Pistachio
So could you just tell me if im right or wrong, i just have the root and i want to be sure to start installing roms

It depends on the kind of brick.
If your phone doesn't work very well, some apps have forced closes, the phone crashes and reboots several times ... this is not a brick.
In these cases, you can flash a kernel containing CWM recovery (or you have already CWM recovery), and restore the nandroid backup => done!
If your phone does not boot normally into Android OS, but you still can enter recovery and download mode, then it is called soft-brick.
This can be solved by the description you already have read.
If your phone does not boot at all - not normally into Android OS, neither in recovery nor in download mode, this is called hard-brick.
In this case, it is very difficult and sometimes not possible to solve this issue.
Fortunately, there are only few scenarios which will lead to such a hard-brick.
E.g. flashing a wrong pit file with re-partition option enabled in Odin, interruption of the flashing process at the "wrong" moment, EMMC bug after wiping with a "bad" custom kernel and hardware defects.
So, nandorid backup is a very good and useful idea. And I already had to use my nandroid backups after flashing into "unstable" states.
EFS backup is good for being on the safe side. When something has deleted your EFS data (IMEI, etc.), you can restore this information. But I never had to use my EFS backup so far.
Just to correct your list:
1-Go in to download mode and use Odin to flash the stock Rom
2-Go in to Recovery mode and use the nand backup
3-Use a jig to go to download mode and use Odin to flash the stock Rom
To boot into download mode, just press Volume Down + Home + Power buttons for some time, then confirm with Volume UP, and you are in download mode. (You do not need a Jig for that.)
To boot into recovery mode, press Volume UP + Home + Power buttons as long as recovery menu appears. Can take several seconds.

My phone is hard bricked after trying to install S-Voice. I can't get into Recovery by holding Vol Up/Down and Power Buttons. I can get into Download mode, but when I get there, I'm unclear what to do. I get the screen that says Odin Mode and Downloading...Do not turn off target!!
I let it sit, but nothing happens. What do I do then?
Can you provide more detail on how to unbrick using Download mode? And also about jigs?
Many thanks.

You will need: kies downloaded on your PC, a recent copy of Odin software and a copy of the firmware you want to put on (can be found on samobile)
Make sure (through your task manager) that Samsung kies is not running and start Odin. Put the .tar file (extracted from firmware zip) into pda section, you shouldn't need to mess with anything else, just check that re-partition isn't checked.
Put your phone into download mode and Plug it in. Odin should see your phone and give you a little yellow square, which is the go ahead to start the process if you don't get this yellow square, you may have problems. If you have a USB jig, use that to get into download mode but if you had updated to ICS it may not work

I have kies on my PC and just dl'd Odin. I also dl'd a .tar. I put my phone into Download mode and plugged it in. I opened Odin on my PC, but it didn't recognize my phone (no yellow square).
Ideas?
Thanks for your time and expertise.
Do you have a USB jig and were you on gingerbread or ICS?

Don't have a jig, but can order one if necessary.
I'm running Mystic's Glory ICS.
Hope that helps.
It's likely it won't work mate but maybe give it a whirl. This happened to me and believe me I bugged so many people online and read up on so many possible fixes but in the end I had to send it back to Samsung, I was lucky that I had reset the counters (using my USB jig) and they fixed it for free under warranty. It may be worth getting the jig if only to do that (if it works)

First uninstall kies.
Then download and install kies again so that you have the latest drivers.
Make sure kies trayagent isn't running so kill it in the taskmanager.
Start odin
Put your sgs ii into dowload mode.
Then and not before you did the above connect the sgs ii to the pc.
If odin doesn't say added, try a different usb port.
Hope this helps.

I appreciate your taking the time, but I tried so many different ways to unbrick my phone that I finally mailed it to Mobile Tech Video for repairs for $56.

I9300 phone and flashed I9300 firmware .
No recovery then download mode and flash stock firmware .
No download mode USB Jig to try for download mode .
That fails its a JTag repair .
jje
Yes yes ^^^^in that order
Can you see the welcome screen or anything else? Or it's completely dead?
Pull the battery, wait for a few minutes, if you have a jig insert it in usb port of yor phone ( if you don`t volume down + menu + power buttons all at once). If you come in downloadmode flash a stock rom and after boot you can reroot.
If you don`t have a jig, order one from somewhere. You can not do without it.

Phone unable to power up

I recently flash my Samsung Galaxy S3 to MIUI ROM (miui_i9300_3.6.21_92f38a8c3a_4.1), it is able to flash successfully. However, when in the middle of setting up the phone, the phone hang and auto power off by itself. I unable to power up after that.
I think my phone previous is the stock ROM ICS if not wrong.
I can't even go into download mode by pressing and holding Home, Vol down and Power button. I have also try remove battery and put it back and still can't go to download mode.
Anyone have any solution to recover my phone?
Btw, my phone already over the warranty period, so really appreciate if anyone can help me on this. Thanks!
