[SOLVED] [Q] Getting back to stock ROM

Hi all
I have rooted and unlocked the bootloader but haven't taken the jump and stuck a ROM or kernel on as yet, as am actually quite happy with the stock ROM, and also rely on the headphones, amongst other things - which appear to be a problem on some of the ROMs.
If I do stick a custom ROM on, can I easily get back to the stock one, is there a stock ROM of that which I can flash via CWM ?
I understand that with CWM I (currently) have to instantly stick a ROM on, so presumably cant do a backup of the stock ROM at that point..before putting on FXP or some such
I presume I can use the sony update service, but would that wipe the root ...?
could someone enlighten me
many thanks

Take a backup of what you have now in recovery, and you can always restore.
Also there are plenty of stock .ftfs in the allin one thread in Q&A that can be flashed in flashtool
No.
if you flash cmw from the thread then yeas, but you have unlocke your bootloader, so just flash the advanced stock kernel and then you have recovery without having to reflash a rom...

that has CWM rolled up in it?
and I can simply type
fastboot flash boot Tkernel.elf
using the version of fastboot that came with flashtool
with the phone in fastboot mode (blue LED)?

Rooting .195

Hi guys,
Many of you will be tired of this, but to save bricking my phone, I want to run this past someone first, please.
I'm on UK Branded Orange .195 and wanted root.
-I've downloaded UK Generic 7.0.A.1.303.
-Flashtool is installed.
-Run Flashtool and select the firmware.
-That'll then put my phone back on 7.0.A.1.303? So you can backward flash firmwares without any issues? This won't brick my phone?
-Reboot phone, at this stage it should load and be usable without any other input?
-Then root using BiNary's method.
-Install CWM for locked bootloaders.
Do I then flash a .195 firmware?
Thanks guys, I know it's a pain but just being cautious.

Hmm, when n flash mode, I'm just getting = "For 2011 devices line, be sure you are not in MTP mode"

Yes you can downgrade the firmware this way without any consequence.
Start the phone up (not connected) and turn on usb debugging under settings > developer options.
Turn the phone off, load the. 303 in FlashTool and wait for it to tell you to connect the phone. Plug in the usb while pressing vol-.
After the flash you will have fully functioning. 303 generic firmware.
Root and install CWM. Download the firmware of your choice in CWM flashable zip format. Turn the phone off and on again, and when you see the Sony logo press up repeatedly till it vibrates. You will now go to CWM recovery. Choose factory reset and from the advanced menu clear dalvik cache. Now choose install zip from sd card and navigate to where you put the downloaded firmware and install.
Repeat these steps to reinstall CWM and the reboot fix (you should also put these on your internal storage before flashing). After flash reboot and you will be greeted by your newly installed firmware. Let it fully boot.
Now turn the phone off again and flash the kernel corresponding to your firmware to prevent problems.
I can't make it any clearer than this. All this information is available from the all in one thread in the q&a section and in the threads of the individual firmwares.
Hope it helps.

Worked like a dream. Thanks very much.
I assume this won't prevent me from installing future firmware updates as all it seems here is i'm flashing a .195 rom over a .303 firmware...

Always god to hear. What firmware did you install?
Future releases you can flash the same way you did the .195, just download the zip of your choice and go to CWM.

Hi mate,
Just used [STOCK][ROOTED][7.0.A.3.195][Thats it][29/11/12]
Have thanked you for your post. I'm wondering whether this is a little less smooth, perhaps the 'placebo' affect.
Could I flash your .223 on here, locked and rooted? Where the changes ever worked out for that firmware?

Help. My device is stuck on boot animation - cwm and twrp will not load

The title says it all.
I went ahead and tried to install Paranoid android RC2, I flash it then subsequently the GApps using TWRP. Now, the device is stuck forever in the boot animation and neither TWRP or CWM (installed with DualZRecovery) will work.
Is there any way by which I can somehow revert what has happened here? This has never happened to me before.
Needless to say if I can avoid having a $400 paperweight, I have sworn to never risk custom roms on my main phone again.

Just flash some kernel with recovery and restore your backup. If you don't have backup, download some of stock or custom roms and flash via Flashtool or recovery......or just use search function

As I said, the main problem is that for some ungodly reason CWM is not working despite the fact that it is what i used to flash PA into the phone in the first place. I have never had a case where CWM itself failed. I need to be in Fastboot mode for flashtool right?
Well the phone wont even go into recovery so im not sure how to get it into fastboot.

1. Download some of newest stock ftf and put it to firmware folder in Flashtool
2. Start Flashtool, press flash btn and pick stock rom
3. Press vol- and connect usb simultaneously and wait about 3 min.
That's it.
Your phone is brand new stock :good:

I think it was because I forgot to wipe the dalvik cache after installation of the ROM - although why CWM itself stopped working I have no clue.

How did u unlock your bootloader? Flashing aosp base rom require u to unlocked your bootloader first bcos of the custom kernel..if u unlocked your bootloader, did u fastboot flash boot.img?

Root & Unlock Bootloader for Xperia TX Latest Version

Hi. I wasn't able to understand the process of doing this to Sony devices cause I'm not used to all these sub-branches of steps for slightly different variations and software versions, lol, I understand this is a lot of n00bness for you guys.
I have a stock, legal Xperia TX, software version 9.2.A.1.199 and I want to get it to the point where I can flash custom ROMs. What do I do with it? Sorry for asking, I appreciate any help. :]

You can most likely only flash custom ROMs (that come with a custom kernel) if you have an unlocked bootloader; so first find out if you can unlock it.

What do I do after that? I'm following the instructions here http://unlockbootloader.sonymobile.com/instructions but installing CWM and rooting for my device and it's software version is where I'm at a loss.

Before unlocking your bootloader, I'd backup my TA partition which backs up your DRM keys. If you don't do that, you'll lose them forever (AFAIK), which means no more Bravia Engine. Look for "Backup-TA-9.10" in XDA and/or Google. You need root to do this, which means you'd have to go back to 4.1.2, because there are no methods currently available for rooting 4.3 without an unlocked bootloader.
Once you do that, or if you don't care, and you do upgrade back up to 4.3, flash this kernel, which comes with two recoveries, and then flash any custom ROM you want.
Although, if you do go back to 4.1.2 in order to backup your TA partition, then you can easily root 4.1.2, install CWM, and flash your custom ROM from there, no need to go back up to 4.3.

u can use this.. im also using tx

[Q] Firmware [KITKAT] Plain AOSP for Xperia T

Hey guys.
I currently have open bootloader and I'm with the firmware Ultimate PureXT v4.0 (4.3 JB) and therefore my disposal Recovery (Philz Touch 6 / CW v6.0.4.7).
The question is, if I just go directly to flash the firmware, with subsequent wipes, or previously have to flash a kernel via flashtools.
In case i need to flash a kernel through flashtools, what use, which is within the firmware or that recommend me?
I feel my bad English

Please can anyone answer? I do not dare to flash directly from recovery, without being certain not brik the terminal, not to have a different kernel that I have.

http://forum.xda-developers.com/showthread.php?t=2729509
You mean to install the above linked ROM? Since you already have recovery installed, you can indeed use that for flashing the ROM, no need to flash an other kernel first.
It's always a good idea to make a backup of your current ROM first, so:
- backup
- full wipe (everything except SD)
- flash ROM from SD
- reboot

Many, thank you very much! It is exactly that.
That was my question, the difference in the systems and whether to flash a new kernel, to install the new firmware recovery
As I'm on 4.3 JB not know if I can flash this firmware directly from the recovery going from 4.3 to 4.4 while maintaining kernel 4.3

When you full wipe from recovery, everything is gone from your phone (including kernel), so just immediately flash the zip after wiping to install the new ROM (new kernel is then installed, you won't end up with 4.4 firmware with 4.3 kernel )

I always thought you had to change kernel if the system is updated, or wanted a firmware cooked
