How to downgrade to the stock ROM on the Xperia ARC

Hi,
I am currently using CM9 on my Xperia ARC, there are certain bugs which disallow me to use my Video camera and there are some WiFi issues too. Since the official ICS update is already out for the Xperia Arc, I wanted to rollback to the stock OS.
Can someone please guide me through the entire process or even point out to a post on this forum that will help me in doing so.
I went across many suggested post but there were none for the Xperia ARC.
Thank You.

This is the latest framework for xperia ARC " NOT ARC S "
http://www.mediafire.com/?rtoaz2tc6c7bsjc
simply .. download , extract , flash through flashtool .. It contains baseband , kernel and ROM, all in one =)
BTW , It's not Rooted since It's the latest Official framework
Use the Search button for the Root ..
regards ..

I think the user above means firmware, not framework.
Anyway it's easy, just use Flashtool and official FTF file. As you said you were running CM9 you must already have an unlocked bootloader. These steps are for unlocked bootloader phone and this is how I did it on my Xarc.
Go to this thread:
http://forum.xda-developers.com/showthread.php?t=1330314
and download official LT15i 4.1.B.0.431 Generic Global World (big bold letters, you can't miss it in post #1)
Unrar this file to get the official Sony 4.0.4 FTF.
Then go to:
http://androxyde.github.com/Flashtool/
Click the tab that says "Installation".
(I assume you are running MS Windows)
Download Full Install, Windows Edition - v0.8.0.0
Download Updates, Windows Edition - v0.8.5.0
On your computer run installer v0.8.0.0 first, then run v0.8.5.0 to make it the latest version of Flashtool. Flashtool by default installs to c:\flashtool and doesn't create a shortcut in start menu, so you will have to find it with file explorer (My Computer).
Power off phone. Do not connect data cable yet!
Run Flashtool.
Drag the FTF file onto the Flashtool window.
In the window that appears, leave everything as is, but tick "No final verification" in the bottom right corner.
Click "OK" and wait a few seconds.
When the message appears, hold down the back button on your phone and insert the data cable.
Notification LED should turn green and Flashtool begins flashing the firmware.
Wait until flashing is complete. Flashtool will say "Ending flash session" and say something about phone rebooting when it is finished. Wait about a minute after these messages appear and you can then unplug the data cable.
Now for Clockworkmod:
Go to:
http://forum.xda-developers.com/showthread.php?t=1680793
and download LT15i Arc v2 from first post.
This is the stock kernel with CWM added.
With phone powered off, hold down menu button and insert data cable. Notification LED should turn blue.
Run Flashtool. Flashtool should say "Device connected in fastboot mode"
Click the button in Flashtool which looks like a lightning bolt (the button furthest to the left.) Tick "Fastboot mode" and click OK.
On right side "Select Kernel to flash", find the kernel with CWM you just downloaded and "Open" it.
Kernel flashes in just a few seconds.
You can now unplug data cable and start up the phone. You can give a quick run through the start up settings, language selection etc. before we root. (The only real reason I said to start up the phone is to make it easier to transfer the Superuser install zip to your sdcard from Windows.)
Now root:
Go to:
http://androidsu.com/superuser/
and download Superuser-3.0.7-efghi-signed.zip
from the Eclair/Froyo/Gingerbread/Honeycomb/IceCreamSandwich (2.1 – 4.0.3) section.
In the settings menu of your phone: Menu > Settings > Xperia > Connectivity > USB coonection mode: Choose Mass storage mode (MSC)
Connect the data cable.
When your sdcard appears as a drive in Windows, copy the Superuser-3.0.7-efghi-signed.zip file onto it.
Unplug data cable and power off your phone.
It's important to watch the notification LED for the next bit!
With phone off press the power button as normal when turning on.
Once the Sony logo appears, watch the LED.
When LED turns blue start pressing the Menu button. You have less than 3 seconds to do this!
This takes you into the Clockworkmod recovery.
Use volume up/down move up and down. To confirm use Home button.
Select "Install zip from sdcard" > "Choose zip from sdcard" >
Superuser-3.0.7-efghi-signed.zip > Yes - Install Superuser-3.0.7-efghi-signed.zip
Once the install completes you can go back and "reboot system now"
Your phone should now be rooted.
Good luck.

Hi,
Currently I am on Android Version 4.0.3, with BB 70 and using Arconium MiUi Rom.
I want to get back to GB. I tried to flash the BB 64 and Adv Stock Kernel and TEAM HDPI Rom, but the internal space is showing as 0 and not able receive any sms.
Can i follow this method to get back to GB?

Yes, with a few small changes I believe this should sort you out. As you are using Arconium MiUi I take it that you have unlocked bootloader.
I used this method on my own Xarc to downgrade to GB after testing out some of the first ICS roms in April, so I know this works.
The FTF file you need will be LT15i 4.0.2.A.0.62 Generic Global World which is the latest official GB 2.3.4 from Sony. (Note, this particular version can only be rooted on an unlocked bootloader.)
IMPORTANT: Never downgrade arc to a version of GB older than 2.3.4, because you will get the 0% battery problem which can not be repaired. The safe FTF files are LT15i 4.0.2.A.0.42 or LT15i 4.0.2.A.0.62 which are both GB 2.3.4 .
The main change is when it comes to the Superuser/root and CWM steps.
I would do it in this sequence:
1. Flash the GB FTF
2. Boot up the Gingerbread and copy the Superuser-3.0.7-efghi-signed.zip to the sdcard from Windows. (You can of course also put Superuser on the sdcard at the start if you wish. I just like to see that the unrooted firmware is working okay before I make any changes to the system files.)
3. Instead of flashing a kernel to the phone, I use Flashtool to "hotboot" a kernel with CWM recovery.
4. I use CWM of "hotboot" kernel to install the Superuser/root the phone.
In greater detail:
1. Get LT15i 4.0.2.A.0.62 Generic Global World from:
http://forum.xda-developers.com/showpost.php?p=18997655&postcount=1
Flashing this FTF is same steps as for the ICS in previous post.
2. This part is straightforward, just get the Superuser-3.0.7-efghi-signed.zip on to the sdcard.
3. From http://forum.xda-developers.com/showpost.php?p=18997655&postcount=1 scroll down to heading "[Tutorial]Root with recoveryLT15i". Download the file "Recovery.rar" from that section.
Extract the file recoveryARC.img from the RAR file.
Although the RAR also contains instructions for using commands to hotboot, I personally think the easiest way is to use Flashtool.
So we want to hotboot "recoveryARC.img" :
Start Flashtool.
With phone powered off, hold down Menu button and insert data cable.
Notification LED should turn blue.
Flashtool should now say: "Device connected in fastboot mode"
Click the button in Flashtool which looks like a lightning bolt (the button furthest to the left.) Tick "Fastboot mode" and click OK.
On left side "Select Kernel to Hotboot", find "recoveryARC.img" you just extracted and "Open" it.
Wait a minute while phone starts up. You do not need to press anything, it goes directly into Clockworkmod recovery.
Now you can proceed to root the phone from CWM.
4. The only difference is that in this version of CWM you must use power button to confirm your selections rather than Home button. Otherwise rooting GB from CWM is same steps as ICS in my previous post.
Disconnect data cable and reboot. Gingerbread should now be rooted.
Good luck!

Thanks a lot mate..It really worked. Now I am back on GB with Internal space problem solved.
Your detailed post really helped..Now I can go for any GB custom ROM..

RxHy

A factory reset wont do the job!
http://talk.sonymobile.com/message/198483#198483 . A well-explained thread,and assuming you dont want/(haven't yet) to root your your phone(since u recently bought it),you can use this.Or else a better option would be rooting it and using a custom gb rom,since it gives you a much better experience.Use the search for rooting or other info.

Simple guide:
1.- Download flashtool. In the folder you install it you will find drivers folder. Run the program and install drivers for your device (if they aren''t installed yet)
2.- Download any 2.3.4 GB firmware, I would recommend you 4.0.2.A.0.62 firmware. 4.0.2.A.0.62 firmware for ARC S // 4.0.2.A.0.62 firmware for ARC. Introduce that firmware you downloaded in the folder firmwares (inside the flashtool directory)
3.- Turn down your phone. In flashtool, press the thunderbolt symbol, and press flashmode. Then, a list will appear. You must select the 4.0.A.0.62 fw you downloaded (and inserted in Flashtool/firmwares). When the PC is ready, will ask u to connect the phone in flashmode. Press back key and then connect the phone to the computer. A green light will appear in ur led. When finished, take the phone and reboot, you will have Gingerbread 2.3.4 in stead of ICS 4.0.4
Hope I helped u!

Sir, I am trying to flash my arc S for downrading to GB. I have the LT18i_62.ftf. Is this safe?
Also I am stuck in the "turn off your phone/hold back key" step....while holding the back key, says 'driver not installed even if i did already install drivers from driver-tools folder.
Thanks much.

It does sound like a safe file.
Install the drivers from Flashtool folder 'drivers' (by default C:\Flashtool\drivers).

[ROM][ARC/S]JELLY SANDWICH 4.5[09.09] Sonys logo problen

Well people, I have some problens on my Xperia Arc S GSM
The problem is the rom don't out Sony's logo
I found a Answer to me Question but I don't know how to fallow him
"locked bootlaoder ?
If so you need to flash an official ICS rom with flashtool, root it again, and reinstall x-parts.
Now you should be able to enter cwm.
Then do the full wipe and format system, and flash 4.4 Jelly sandwich.
Always remember that x-parts installs a recovery in the /system folder, not in the kernel (as it is on unlocked bootloaders), so if your rom is messed up, you can't access the recovery anymore and need to reinstall x-parts again, and for this to be done, you need to flash an official rom with flashtool first then root it."

Try
Use sony update service to repair the phone or flash a generic ROM.
For flashing ROM:
1. You need latest flashtool. Get from here http://androxyde.github.com/Flashtool/
2. ROM (in .ftf format) - Download the ROM that you need.(Search in xda forum)
The methods and procedures discussed here are considered risky and you should not attempt anything if you don’t know completely what it is. Do this only if you’re capable of getting your phone back right on your own. If any damage occurs to you or your device, we won’t be held liable. You only will be responsible — you’ve been warned. Okay!
This process will clear all user data and applications.(contacts, messages, call data, apps, apps data etc.,) . Please take backup of all your data before you start.
Instructions:
1. Switch off your phone and put it aside.
2. Extract the “FlashTool_x.x.x.x.exe” file on your PC (you can just double click on it to extract)
3. Few files and folders will be extracted — the two which we’ll be using are the ‘drivers‘ folder and the ‘firmwares‘ folder.
4. Inside the ‘drivers‘ folder there’s a file named “ggsetup-2.2.0.10.exe”, double click on this file to install the proper driver on your PC.
5. Now copy the “.ftf” firmware file that you downloaded for your phone, and paste it inside the “firmwares” folder.
6. Double click the “X10FlashTool.exe” file.
7. Once the program opens — click on the “Flash” button.
8. You’ll see the firmware that you copied in Step 5 loaded on the screen — click “Ok”!
9. Now it should ask you to connect your phone to the PC. So first plug the USB cable to PC, then pick up your phone and hold the “Back” key (key at the bottom left on
your Arc), and then connect the USB cable to your phone. Remember you’ve to hold the “Back” key while connecting the USB cable to phone.
10. Once the phone gets connected — Flashtool will automatically start the flashing process.
11. Keep an eye on the Flashtool’s screen.
12. And once the process gets finished, disconnect your phone from PC and switch it ON.
13. Don’t freak if it takes longer to boot (that’s normal) as the phone has to build the cache again after flashing.
Enjoy!!!
Hit "Thanks" if anyone helped you. :good:

I have tried google search to find an alternative and I have come across one file with the same name, I flashed it with Flashtool and now my Xperia S won't boot, I can get into flashmode and fastboot but that's it.

Thank you very much. This worked. I didn't know flashing a stock .ftf firmware would re-lock my bootloader. It did I flashed LT26i_6.1.A.2.50_1257-5499_WORLD and after that was able to upgrade through PC-companion without any problems. Thank you for the help.

Ok. I assume you installed Flashtool. Did you install the drivers and put the FTF files in the firmware folder in the Flashtool directory?

There should be a button with a lighting symbol. Click on it and select flash mode. Select FTF and the program will do it from there onwards. Just follow the instructions.

1) Download flashtool, on sony website they told us to download emma software but did not work out for me so i downloaded flashtool directly here from this link
http://forum.xda-developers.com/show....php?t=2335555 (plz check this link twice, dont remember from where i downloaded flashtool software could be this one , sorry googled lot of links for this software
2) download ftf file from this link
http://forum.xda-developers.com/show....php?t=1681542
3) flashtool will go directly to C drive which must be your main drive
4) go to c:/flashtool/firmware and delete anything you have in there
5) when its empty copy ftf file from step 2 and paste it in here
6) open flashtool, click on bolt sign and select this ftf file
7) take out battery of phone, put charger in phone and press back button to enter in flash mode
8) press flash on flashtool software and wait for completion of process
ALL DONE ...
