You first need to register in order to download it. After that just key in the details and download the right firmware as Jeetu said. You can then follow the tutorial on galaxys2root.com to unroot your phone!

You need Odin to flash and you need to install kies on youur computer for USB drivers. The rest is out there, Google is your friend!
Hi,

kies is already installed, but where can i get odin and a short link to guide would be nice.

Flash stock rom after resurrection remix 1.9.1

Hi guys,
My friend's got a problem. He installed resurrection remix v 1.9.1 by westcrip 4.0.4 on his s2.
The kernel is:
3.0.31-siyah-v.3.2.4+
[email protected] #32

He didn't do a backup before installing it and now he wants the original rom back. Could anyone here tell me exactly what he has to do?
He doesn't know anything about flashing roms etc and he did it as in the tutorial to get resurrection remix, so we need an easy tutorial (I don't own a s2 so I can't help him much).
His S2 has no branding.
Thx and please help!

Only your friend can know what firmware was on his phone before flashing the custom ROM. I suggest to use CheckFus to get the latest official firmware for the phone and then flash it using ODIN.

Using CheckFus is self-explanatory and for using ODIN there are already many excellent and easy to read guides here.
So CheckFus will tell which firmware is right for his device? It will tell exactly which firmware?
And could you post a link to a thread, where is explained how to flash the firmware using odin. Cause I don't understand anything about basebandkernel, and we don't know which firmware was there as he bought the device and which kernel and which baseband and whatever. Is there any tutorial for noobs?
Could you excatly post which firmware we need from here to get phone back on stock ics? We want a german firmware if possible. (I know you could just say ask google, but at xda heres a great community and I don't understand anything of odin and want to know which files exactly I have to download for phone, pda and cdc. That would be so great!)
Please help us!
Thx in advance!
Michi
EDIT:: I found this here: http://androidfirmwares.net/PhoneFirmware/Download/120
Can I download there and then I have to put them like this:
PDA: XWLPF
PHONE (Modem): XXLPX
CSC: OXILP6
?
And then get s2 to download mode?
And what about the kernel? There is this kernel on s2 right now:
3.0.31-siyah-v.3.2.4+

You will have to do quite a lot of reading. Start by reading the Stickies and then read this thread which explains how to use ODIN.
Remember: only fools rush in - take your time and read before flashing
Thanks a lot, but what about kernel now? We'll have to read the thread, but I just want to know if the firmware from android firmware was right and if I could flash the rom if I just put these 3 Phon,Pda and Csc in the fields and without repartition. So what about the kernel?
Sorry if I nerve you, but I'm a noob with s2/flashing etc and it's not my phone
Thx!
Michi_optimus_me said:

The kernel is part of the stock firmware.
So we just need to place these 3 files in the right order in odin (PDA: XWLPF, PHONE (Modem): XXLPX, CSC: OXILP6) and go in download mode on galaxy s2. Then we can flash the firmware which is stock? And then we can update via kies if possible and use kies and etc? there's nothing else to do? And after the we have warranty as if we have just bought it?
EDIT:: I downloaded it but in the 7z file there were only boot modem cache etc and these were iso files? What have I got to do? Where can I download just pda, phone and csc? I dont get that!
Pls help!

You can try www.sammobile.com for stock firmware too. You'll have to sign up, but it's worth it. You just search for the stock firmware for your device and flash through Odin. Do not use the repartition button or the pit file and you should be fine.

I doubt that, the 7z file contains one tar.md5 file. Do not untar it, no one said you should do so. For ODIN read and follow the instructions according to the link I posted in post #4. That thread tells you what to do with the firmware file.

extract the file u downloaded from samfirmware or checkfus
u will have two files in it (in Latest gb or ics)
insert it in pda and flash
and ur done
the kernel is included in the firmware ..
Thx guys now I hope this is my last question on this topic:
I read the guide and downloaded a firmware. Now I don't understand the thing with checkfus. Do I really need checkfus or can I just download this firmware for a s2, unbranded, bought on amazon and it's a german s2?
Can I only put this extracted .tar.md5 file in PDA Section in Odin, boot s2 into download mode and connect to pc. Then click start and everything should went fine?
I own a xperia mini pro and there I must flash kernel and then firmware, so at odin and s2 the kernel will be changed when I flash pda and is included in pda?
Sorry, I asked same before, but I don't really understood
Thx for your great answeres, xda is a super community!

CheckFus is used to download the latest firmware. As you have downloaded the firmware from somewhere else, you do not need CheckFus anymore.

Flash stock rom after resurrection remix
I just reflashed my samsung J-500H with the stock rom after gapps started crashing on resurrection remix. I had no problems going back to stock except the I had a boot loop for a few times my remedy was to do a data and factory reset on stock recovery. I will reflash RR after I find gapps that would work on my J5 Lollipop. Any suggestions?

Update from I9300XXDLJ4 to I9300XXDLJ5

Hi, as the title says I have I9300XXDLJ4 and I would like to update to Indian I9300XXDLJ5; as this is not available with my CSC, I'd like to update just the ROM and the modem.
Is there a way to do this? It should be enough, as the RIL files should be in ROM, right?
Thank you and regards!
flash via odin

Good Question :highfive: :silly:
By the way..are you trying to increase your post count????
Just asking..
Anyways..there are atleast 4 threads with the same purpose in the General Section (Last I counted)..and numerous others asking the same question which you have asked...
Don't you think...creating a new thread just for it was pointless??
[EDIT] After having another look ...I believe you don't want to flash the kernel...for it you have 2 options:
Flash via odin: Download the firmware ..extract the tar.md5...delete the boot.img from the archive..pack it again in a tar file and flash
Flash via CWM..download the ROM..delete the boot.img from the zip....go inside META-INF>COM>GOOGLE>ANDROID>updater-script and delete the commands that flash the kernel..

Yup! There is always a way to do it on XDA.
You can use Odin to flash the firmware to your phone... it's much better than Kies trust me.
Here is the complete step by step guide to update to the latest firmware.

Right. Nobody is going to hold your hand through this. You want your phone fixed, you're going to have to fix it.
The guide in that thread is valid. If you want stock roms, go to Samfirmware, AndroidFirmwares.net or get the PC version of Checkfus & download one.
Get a stock rom, flash it in Odin as per that guide. Done.
You have some reading/searching to do.

[Q] how to unroot my s3

Please can anyone help me?
I need to unroot my s3 and put a UK T-Mobile ROM back on it as I am exchanging it for a new one through insurance due to dropping the phone.
The screen still works but has a small crack in it.
Cheers in advance
Go into the general section and follow the unroot guide.
Basically you need to reset flash counter by downloading TriangleAway app (its available here on xda) then just download your official rom from http://www.sammobile.com/firmwares/1/?model=GT-I9300#firmware, flash it through odin and restore factory settings. There should be in deph tutorial in general section.
