Flashing back to original rom

Hi guys,
I used the search but i cant find the right answer.
I want to flash my xperia x1 back to the original rom. maybe by using the SE update service if possible.
i recently HardSPLed my phone and used a custom wm 6.5 rom. Can i just use SE update service or a original stock rom and flash it? or do i have to restore my stock SPL first?
Thnx for your time

Well, there are many questions like yours and all have been answered..., just do search a little bit more. For example, read this thread.
But, maybe this will help :
1. Download stock ROM from this thread.
Run the program and rename the extracted program to "RUU_Signed.nbh" if you want to use CustomRUU or rename to "kovsimg.nbh" if you want to use micro SD method.
2. Download stock SPL from this thread.
Flash your device back to stock SPL.
So, first, flash the stock ROM, then flash the stock SPL.

[q] i9000adjf1

Hi all, I am in somewhat of a confused state right now and hope you can help...
I have one of the first I9000s that O2 shipped here in the UK. My phone reports firmware of PDA/Phone I9000ADJF1 and CSC I9000O2UJF2. As I am in the UK I would have expected this to be one of the I9000XX firmwares and cannot seem to find any reference to the AD firmware anywhere.
Can someone shed any light on what the AD firmware is? Could it be that it is O2 specific and if so, do you think that flashing an XX firmware would cause a problem? I am just a little concerned about flashing this when 2.2 is officially out, hence the questions.
Please forgive my ignorance if the answer is simple, this is my first android phone
Bob

Before you do anything...
PLEASE back up your phones rom and host it online!
there are several of us on this forum who have o2 UK phones and have since upgraded losing our original firmware. If you upgrade and dont back up your original rom you cant send it back for warrenty!
So at least make a backup using odin, or if anyone else knows the way to extract the rom please say now lol.
Other then that I9000ADJF1 is fine for flashing I9000XWJM2 or any of the other european ones. the AD just stands for '02'

Will ROM Backup within ROM Manager do as a backup? I had to Root the phone, then backed up ROM to SD card. I got same ADJF1 Rom.

use clockwork recovery from ROM Manager (from the market) and do a nandroid backup

Ye. This is what i did. I just wander what it will contain rppted image. I will probably enable to unroot it later. Will all get back to normal(unrooted phone with warranty) then official froyo arrive?

[Q] How to return to stock?

I have not flashed a ROM yet, but when I do how would I go back to stock? I made a CWM backup of being stock rooted, but I want to know of another way to go back. When I had the AT&T Galaxy S2, all I had to do was flash the tar file in Odin. I searched the development section and only found modified KJ4(2.3.5) and KKA(2.3.6) ROMs. I have the Polish Note if that matters.
Edit: I think I may have found the right way to go back to stock KKA. Just by placing the stock zimage using Chanfires method ^_^
Edit2: Meh figured it out

Get the stock rom and reflash it.

Yeah I definitely know that part, I'm more concerned about the way of doing it.
I heard that flashing through Odin would cause the yellow triangle as it would set off the flash counter... Can please you link me to the stock ROM that is flashable through Odin if this isn't the case? OR an alternative method besides the one I posted above.

I do in fact have tha same questions. I even went off topic in a ROM release thread about it.
I'm a longtime HTC user and with long time i mean since like 2002ish. I have no fear to mess around with HTC stuff since I know my way around and know exactly how to brick it, if I really want to ;-)
Things look different with the Note thought. The recovery doesnt stick but is kernel dependant, Odin seems to be similar to HBOOT but shouldn't be used since it tells Sammy what one did to its device. Flashing can be done by this that or another way, it all looks so weird and chaotic to a HTC camper... lol.

Cheers guys for the great info .
ive been following this thread for a while now , and i would like to suggest to the experts , if possible , to make a full step by step guide for how to revert to stock (including the whole stock kernel re-flashing process for different note models) bcos to be honest , i think many of us have this same question and are hesitated as the whole process sounds confusing.
i could be one of them as this is my first samsung device , coming from HTC Desire HD ,where flashing and development for samsung devices (as far as i know) is quite different from that on HTC devices.
Thank you again for the efforts , would be highly appreciated to get that guide post up.

Yeah he did update it. That's where I got the idea about just using Chainfire's Initial Root Flasher and placing the zImage in that folder. On the bottom of the OP, he put
Now How I can revert back to Stock ROM/Unroot (In case of replacemet may i need)
I you have Just rooted only but not added CWM - Just Download this Extract - Execute - Rum Me unroot.bat
If You have Root + CWM - then first find out original stock kernel (zImage file)
Now place this file in zImage folder, n repeat procedure(Initial CFRoot Flasher), which you have done at time of pushing CWM by selecting I am rooted already
Now unroot with above said unrooting tool.

i have afew questions about that ,
where and how can i find the specific zimage for my device ? i understood that its in a compressed file extracted with 7-zip , but how can i get that compressed file ?
also , what if i had another type of ROM installed (NON stock) , how can i flash the original stock rom back (since i will not be be rooted, wont be able to restore NAND backups)??!
in HTC devices (i had Desire HD) , reverting to stock rom is simplified by flashing the "RUU" files , which were found in a dedicated thread.
This whole samsung diferences is really confusing me
thanks alot for any help.
cheers.

This is my ass-umption as I am still waiting for other responses as well.
In order to revert to stock you have to download the Initial Flasher.zip from Chainfire.
Then download your Kernel from the first page. http://forum.xda-developers.com/showthread.php?t=1331784 The zImage is taken from extracting your Kernel, whether it be KK1, KJ4, KKA, etc...
You place that zImage in the files folder and click "already-rooted.bat" *if you are coming from another ROM.*
Once that is done, you run the unrooting tool from Doomlord.

This method may work if you are able to access your device. As in your Android OS is up and running. What about a bootloop on a ROM/Kernel without a custom recovery built in confused. How would you go on from here?
On a part-bricked or bootlooping or otherwise fukkered HTC I would fire up my (bien sure as first thing) flashed ENG HBOOT, put it in FASTBOOT mode and simply a) fastboot boot c:\path\to\file\recovery.img or b) fastboot flash recovery c:\path\to\file\recovery.img and done. No brick from here, bc I a) always can restore a nandroid from here or b) always have a ROM ready on the SD or I could put it there using the mount usb option in the recovery, or heck, even by ADB PUSH. But on a Samsung...

[Q] How to restore the factory default ROM on G-Note?

Hi,
I installed RocketRom v.23 and so far it is great, aside from some minor issues.
However, as I need to return the phone back for some other reason, is there any way to find what was the original ROM on my phone before I install this custom ROM on top of it? Maybe from the IMEI or sth???
PLEASE ADVICE cause I know they will not accept it without the original ROM.

It is not possible to know
But you can find ROm for your country from here N flash it with PC Odin.

I think you can check the date of your purchase invoice of the device and find a rom released before that date and flash it. You can find the date adjacent to rom details in Dr. Ketans thread.

this is the answer. you dont need the exact rom on your phone before. you need to find any rom that you could have upgraded your phone over kies.

Please help me revert back to stock rom! I've read guides but I need more help!

Hey guys I'm in a bit of a pickle.
I have a Samsung Galaxy Tab 8.9 WIFI/3G (Model GT-P7300 I think).
I somehow managed to install Overcome ROM on it when I first got it. Now I want to give it to my Dad and I would like to revert everything back to factory default stock and all. I'm not sure what a Kernal is and not sure if I need to revert that too but probably.
How do I best go about this? I am having much difficulty understanding from googling and reading forum posts and I am not familiar with the acronyms and lingo the community uses. Would you be so kind to please explain to me step-by-step detailed as if I was a child lol
Please link me to everything I need to download!
Oh and another thing: I bought this tab in Asia so it has English and other Asian languages installed. Can I install a different language ROM for my Dad? (I think he prefers Swedish). Will it be locked to any providers or anything?
Thank you very much in advance. I really need help with this

Here's the stock unbranded firmware for Nordic countries
Here's the branded firmware for Telia (couldn't find any other carrier branded for Sweden
Then just flash using Odin, that will wipe everything though, but you'll be back to stock

I don't understand how to flash with Odin .. I don't even know what Odin is! Please give me super simple instructions
I downloaded the firmware file and I put it on my tablet's SD card. I rebooted into Recovery mode and I try to apply the update from the ZIP file. But it says it cannot Open it?! What am I doing wrong?

All is explained in this post here, that is stickied at the top of this section

overome is quite a standard rom with features that are not really seen... the look is stock... I don't see a reason to revert back...

Thanks guys, I successfully flashed with Odin and I think it was a success. You have been very helpful.
But I am still not sure if 100% everything is set to default stock in case of a future warranty claim. Is there anything else I should do? Do I need to install stock Recovery as well?
Thanks again.

If you used Odin and one of the stock firmwares then it should have flashed a stock recovery as well IIRC, I'm pretty sure Odin on these tabs does the whole kit and kaboodle when it flashed
