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

Hi, i got an arc s recently and updated it to ICS. It lags a lot now and i wanna revert to GB. Can a factory reset get it back to GB or do i absolutely have to flash it in order to do so ?
Thanks.

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).

Step 2 : Unlocking Bootloader on Xperia S
Step 2 : Unlocking Bootloader on Xperia S
Procedure To Unlock Bootloader of Sony Xperia S LT26i :

Now, We Will Unlock The Bootloader,
Why to Unlock Bootloader?
1.) You can flash custom ROMs/Kernels
2.) You don't need to worry if the new firmware can be rooted or not as with unlocked bootloader u can always ROOT Your device
[ Before We Begin Unlocking Bootloader ]
Get the IMEI code for ur device: type *#06# in phone dialer to find it out, note only the digits (no dashes)
Make Sure The Fastboot Drivers Are Installed.
Make sure u have a windows PC with USB cable to connect the phone
Power down ur phone and keeping the Volume Up button pressed connect the USB cable to PC this will trigger FASTBOOT mode and windows
Will start driver installation, extract the above package and point the driver install to that location (usb_driver) folder
Once drivers are installed just disconnect cable and power on device.
[ How to Unlock ] (Official Way)
Video Link ---> http://www.youtube.com/watch?v=LRH3pC7MhEA
For better understanding, I highly recommend you to watch the above video along with the instructions below:
1.) Download ‘Fastboot Drivers And Pacakges File For Xperia S’ file from → Here
2.) Extract the file you downloaded above on your PC. You’ll get the following three files:
drivers.zip
fastboot_with_Android_USB_file.zip
3.) Go to: http://unlockbootloader.sonymobile.com/ and read everything!
This will open a web page in your default browser. Scroll to the bottom of the Instructions on the page and you’ll see a link like “Continue”, click on it.
In the pop-up window click “Yes, I’m sure” and then in the next window click on both the checkboxes, and then click “I accept”.
4.) Now insert the details as per the instructions:
First 14 digits of your IMEI No. Do NOT enter the last digit (15th) in the box. To know your IMEI No. dial *#06# on your Xperia Arc.
Your Name
Your Email Address
Click Submit.
5.) You’ll get a KEY to unlock boot loader. Write it down somewhere you can remember, it will be used later.
6.) Switch off your phone.
7.) Now extract the “fastboot_with_Android_USB_file.zip” file you got in Step 2.2.
8.) Pick up your phone (it must be switched off) and hold the “Menu” button (the key at the bottom right of your phone), now while holding the “Menu” button connect your phone to your PC with an USB cable.
9.) Once connected — the LED light near the phone’s USB plug will turn blue. If it doesn’t — repeat the Step 8.
10.) Now to install the drivers do the following:
Extract the “drivers.zip” file you got in Step 2.1
Open “Device Manager” on your PC and look for “S1Boot Fastboot” under the head “Other devices”
Right-click on “S1Boot Fastboot” and select “Update Driver Software…”
Now select “Browse my computer for driver software” and select the folder where you’ve extracted all the three files you got in Step 2. Once done — click Ok.
Now click Next (Make sure you’ve ticked the “Include subfolders” checkbox).
If you see any Windows security warning box, don’t worry . Just select “Install this driver software anyway”
Wait for “Windows has successfully updated your driver software” message to appear on your screen. Now click Close.
11.) Open the “fastboot” folder from the file we extracted in Step 7.
12.) Now hold Shift and press mouse right click (Shift + Mouse Right Click) anywhere on the empty white space inside the “fastboot” folder. And then select “Open command window here” from the context menu.
13.) Now in the command prompt window type/paste the following:
fastboot.exe -i 0x0fce getvar version​
14.) It should return a value like “0.3”. This ensures that your device is correctly connected.
15.) Now type/paste the following line in the command prompt window:
fastboot.exe -i 0x0fce oem unlock 0xKEY​
IMPORTANT! Replace the word “KEY” from the above line with the KEY that you received in Step 5. Then Hit Enter.
Click to expand...
Click to collapse
16.) Now wait for the process to complete. Command prompt will show a “Finished” message when it will be completed.
17.)Once it’s done, disconnect the USB cable from your phone and switch it ON.
18.)Your phone’s boot loader should now be Unlocked.

Troubleshooting
If you experience a bootloop (phone constantly reboots and reboots on the boot screen) or a soft brick (powering on the phone shows an orange triangle with a phone and computer), don’t be afraid. XDA to the rescue!
For a bootloop:
Hold The Power Button And Volume Up Button
If You Hold For 3 Seconds = Soft Reset = 1 Viberation
If You Hold For 10 Seconds = Hard Reset = 3 Viberations***
Power on the Phone Again, Keep pressing Volume Up Button
Your phone will boot into recovery.
Select “Wipe data/ Factory reset”. (Volume Up for going up and Volume down to go down)
After the reset is done, select “Reboot system now”.
The phone will reboot and you should be all fine.
***Do Not Try Hard Reset Untill And Unless The Phone is Facing Major Problems,
For a soft brick:
You probably flashed some faulty firmware or firmware not meant for your device.
The File You Downloaded Must Be Incomplete.
Download the correct firmware and flash again.

Hi, I searched a lot for the way to flash a custom rom on my Xperia S. But now halfway through, I've got a problem. My device says it does not allow to unlock bootloader, so does that mean that there is no way I can flash a custom rom on my phone? :crying:

You can use only Stock based ROM for locked bootloaders, not the unlocked bootloaders one.

Which recovery are You using? The 2.8.1.0? It doesn't work with Xperia S. Use the 2.8.0.1 version.

Wait i will let you know the complete story.
so what happened is
first i was on CM11 for few mnths then switched to MIUIv5 for 1 month. everything was working fine
but when day before yesterday i flashed PA rom i am not able to access the recovery now (previously there was TWRP in my XS). now i can't flash any zip file
when i reboot to recovery it gets stuck on black blank screen. Even the recovery apps like twrp are not working. when i tried to install recovery through app, the app crashes.
As recovery is not working i cant even switch to other roms or any zip file.
i am totally stuck on this ROM
i asked this que on sony mobile group on FB (created by some sony fans), one of the member said "probably this is not ROM fault but the kernel fault. consider trying new kernel"

If You are on Beta 6 of PA, it doesn't have twrp or cwm. Flash the twrp v2.8.0.1 by terminal emulator method.

Ah yes, even that one doesn't have recovery.
Unlocked bootloader is must.
You need an Android app. You can find the app here. Also, here is the page of the twrp.
What You need to do is, download the twrp from here. Rename it to fotakernel.img .
Then copy it to Your sdcard.
Then run the following commands on the terminal emulator app:
Code:
su
dd if=/sdcard/fotakernel.img of=/dev/block/mmcblk0p11
TWRP installed!

[Q] Help unlocking bootloader, root and flash.

Hello guys, i have a xperia ZQ C6503 Brazil, i want to unlock the bootloader , install a recovery and a stable cyanogen mod , but the cyanogen installer shows the device is not supported ( they are not equal the ZL ? ) , i want a correct step-by-step for this things i want, i am confused with tons of topics with differents things..
So i want a how-to Unlocka bootloader, install a custom recovery, how to root, and how to install the cyanogen mod without the windows installer if possible. thanks.

ZQ it's exactly the same of ZL, I don't know why Brasil changed the name, I have a ZQ and installed the cyanogenmod 11 for ZL and everything works, don't worry about that. I can see you're a little insecure, so I suggest READING MORE TOPICS. And make sure that you're installing everything for xperia ZL (ODIN) and not for the Z (yuga) or Z1.
First: read this .. http://forum.xda-developers.com/showthread.php?t=2201148 READ EVERYTHING, DOOMLORD IT'S THE MAN !
AFTER READING DOOMLORD'S TOPIC: IF it's not clear, you can read http://techglen.com/2013/11/28/install-android-4-4-kitkat-on-xperia-zl-with-cm-11/# and http://wiki.cyanogenmod.org/w/Install_CM_for_odin
Suggestion: Use flashtools to install the custom kernel (connect the phone in fastboot mode, click on the lightning, choose fastboot mode and choose install/flash custom kernel) it's way easier than using terminal.
After installing adb drivers, sony drivers, fastboot drivers, and etc ...
1) unlock bootloader
2) download the last cm11 nightly and google apps for android 4.4.2 (search on the cyanogen site)
3) on the phone: put the .zip on the root of sdcard ........... on the pc: extract the .zip on desktop (you're just gonna use boot.img)
4) shutdown the phone, plug the cable on the phone pressing VOLUME UP ( + ) , a blue led should appear
5) open flashtools, click on the lightning and choose fastboot mode, after choose install/flash custom kernel and choose the boot.img that you placed in the desktop
6) Unplug the cable and reboot the phone (or it'll reboot by itself) WHEN SONY LOGO APPEARS (A PINK LED WILL APPEAR, this is the phone telling you that you can press volume up (+) to open recovery), so, when the pink led appear push the volume up (+)
7) Now you're in clockworkmode recovery, wipe cache/data/dalvik, flash the rom, flash the gapps, flash the supersu.zip(if you want it rooted)
8) Reboot (it may take a while, up to 5 minutes)
9) Have fun

[Guide] Installing Custom Rom Xperia Ion (CM)

I have made this thread as a desperate attempt to minimize questions such as the one that follows. I have seen these questions clog up development threads and the responses are usually short and the user if extremely new to android, gets lost.
In making this guide, I have chosen to use the custom rom: CM-10 for Locked Bootloaders Rom shared by @optimumpro
I chose this rom due to the simple fact that the question was based from that thread AND because I myself use this rom.

Sorry to bother you all with my annoying questions, but, as far as twrp or cwm go, will titanium
backup suffice and how exactly do I install the rom?
Sent from my LT28at using XDA Free mobile app
Click to expand...
Click to collapse
The instructions as given are
1. Have JB latest Stock Kernel, Roger's Baseband in case of LT28i, Root and Recovery
2. Format System/Data/Cache in TWRP or Mount and Format the same in CWM
3. Install the ROM and Reboot. Nothing else is needed
here is the general breakdown if you are moving from Stock on XPERIA ION to in this example, the CM 10 rom for locked bootloaders.
------If from ICS, follow from step 1
------If from JB, follow from 1a
1)
1a)----Flash----
-You need flashtool (http://www.flashtool.net/index.php)
-You need the firmware (http://forum.xda-
developers.com/showthread.php?t=1752345)
You need to download the JB for Generic International Firmwares - LT28h and if you wish to have LTE for AT&T devices then
you must also download the latest JB for rogers (Rogers Stock Firmwares - LT28i)
First, Flash the Generic Ftf
(optional) For LTE, flash the Rogers Firmware with EVERYTHING excluded except for baseband
1b)----Root----
There are a few methods but personally I use:
http://forum.xda-developers.com/showthread.php?t=1886460
Download the current version (happens to be v33 at the moment)
-Connect phone to computer with Android Debugging Enabled with Unknown Sources
-Run the required File and follow the instructions in the Command Prompt Window
--It will complete the required steps and upon reboot, you will have root access.
-Install Busybox after root
1c)----Recovery----
-http://forum.xda-developers.com/showthread.php?p=30149181#poststop
--Download RECOVERY for XperiaIon v.4.zip
-Connect phone with same requirements for root
--extract and run the .bat file->done
MAKE SURE YOU HAVE THE SPECIFIC ROM YOU WANT ALREADY ON YOUR INTERNAL OR EXTERNAL SD CARD BEFORE CONTINUING you have been warned
2) CWM MENU SELECTION
-Upon Reboot a BLUE LED should appear, immediately hold the volume DOWN key, CWM menu should appear
--Scroll using the volume and select using the power key--
-Go to Storage and as instructed by the CM 10 Rom I specified, wipe System/Data/Cache
For more information on the CWM menu breakdown visit:
http://forum.xda-developers.com/gala...neral/ref-cwm-clockworkmode-menu-options-t1542857
------OPTIONAL BACKUP------
-If you would like to make a backup of your current rom, go to option 4 the Nandroid menu and select the Backup Option
3) INSTALL
Then go back to main menu, to go the INSTALL MENU
and select choose zip from (external/interenal (depends on where you stored the zip))
-navigate to zip location-> select-> yes-> install
-----wait patiently-----
Reboot
Done

I think you should talk about making data backup too. For a newbie, he may never know that he should first have a back up and how to go about it.

Dude if you are on stock ROM then navigate to
settings > about phone > build number
(Download specific kernel from that three options that matches your build number and flash it)
