As @gm007 said, it is advisable that you do a repair using SUS before doing anything else.
After that, if you're still on an older firmware (going by your signature) download any full .253 ftf (Find it here) and flash it in flash tool.
Ensure that you wipe everything when flashing.
Once you've updated to .253, root it & install 2.4 release dual recovery.
Then follow the instructions from here to update to .423.
If the instructions are unclear, just ask, I'll elaborate on whatever you didn't understand.

I think the problem is not the rom cause now i am on 4.2.2 leaked but this happened on others updates official

@kgs1992
Not to argue with you, as you seem like a helpful person, but why advise to update to 253 first, when they could just jump straight to 423 and root it with Doomlord's tool if they require root?

I'm not sure if there is a full ftf for update to .423, that's all.
And @[NUT] had advised an update from .253 or .307, but it seems the guide now says that you can also update from .350 or .434
I'm limited by my own knowledge, sorry.

Nobody needs to be sorry for helping others
There are quite a few 423 ftf available in the general section.
I used this version - http://forum.xda-developers.com/showthread.php?t=2336874
There are a few more for different regions/customisations posted in that section

OP is on neither of those firmware versions, but yes, using a full FTF for .423 there shouldn't be any problems coming from .407. The only potential problem could be if the ROM you're coming from contains a different NFC firmware and the destination ROM doesn't flash a compatible version. But since .423 does do this there shouldn't be any problems in this case

So i should install .423 via flashtool?

Yes. Then root and restore TA partition if you have that backed up.

I'm not sure how the FlashTool process works. Does it wipe the data partition? If so there might be an option to not wipe it, I don't know. But if your device is rooted you can just back everything up with Titanium Backup (make sure to backup to external SD card) and restore the data for those crucial apps afterwards.

[Q] Confirming the Stuff i need to do

NOTE: MODS, i know i could have used an existing thread for this, but i need the information in a proper way and maybe ask some repeated questions.
Hi guys,
I recently bought my first sony phone. Mighty impressed, i must say. Being an old HTC fan, i didnt expect i will ever make a jump, but this phone hooked me.
I have worked a bit for the development of HTC and some other phones, so i know what to look for and where to. Reading all the guides here, this is what i concluded if i want to safely unlock bootloader and flash some CM goodness. Please read my steps and let me know i am doing the right thing:
1. Root (via Doomlord thread guide. Flash old kernel, use exploit, then flash new kernel back)
2. Backup TA partition (for the precious BE2 and other magical SONY stuff)
3. Unlock BL the official or unofficial way, (as it doesnt matter because i can always relock it using TA backup , am i right???)
4. Flash CWM/TWRP etc and enjoy all the custom roms. (never look back)
Much appreciated guys. I will surely contribute with my own flavor of aokp once i get the basics correct. Not so soon.
Regards
neXusPRIME

Yes and Yes.
The steps you described are the proper ones

Yep that's the right steps to do!Have fun unlocking your device

No if your bootloader is untouched it will update you will lose root tho

Rooting will not flash a custom recovery it will just install a SuperSu app and su binary. U can use a stock firmware and flash it using flashtool to get back to stock

One last question before taking the plunge.
What if i flash a generic stock FTF (for my c5303 ofcourse), but not caring about the branding, will that also be okay for OTAs or will i have to repair/update via PCC SEUS?
In other words, how do i know which branding stock ftf do i need? About Phone page doesnt have that info i think.
I am not worried about system partition or anything, but i want to make sure i have stock recovery of my phone which will guaranteed work when i get the 4.3 OTA.
for rest, ill root, flash CWM and nand backup all things.
btw, it was so so easier on HTC

You can restore you phone with SEUS also with Flashtool ofcourse.
It does not matter what kind of firmware you flash as long as it is an C5303 one. I had dutch Vodafone Branded and I flashed a Generic EU one without issue the updates will be provide by Sony and not vodafone (my case).

Used sony update service to repair my phone,
Its back to unrooted stock 254
i think twrp messed something up.
Is it recommended or CWM only works?
on my old phone, twrp was more reliable.
There is something fishy with sony mobiles.
I know the modding stuff is more safe due to flashtool being always available for the rescue, however common stuff such as unlock, TA, recovery and etc are much too complicated for the newcomers.
even being n RC for porting TWRP to two htc phones didnt help me there.
Stuff dont work the first time.
In my case, the problem was,
flashtool worked the second time for flashing 254 kernel
doomlord kit worked the second time for rooting (i really dont know why, but it wasnt related to kit, something up with usb debug n permissions)
installing CWM didnt work the first time as well, (not the fault of installer, rather first time fails coz u give SU permissions just then, so something is missed, 2nd time, the SU permission is already there, so it works)
and ROM flashing almost always needs wipe dalvik/data/cache etc otherwise you might mess something up...
Its a lot safer if i see it one way, because these steps are more foolproof, but on the other hand, a lot more complicated, then say HTC or samsung phones. especially as i havent unlocked my BL so being cautious at every step.
Anyways, all things are fine now, using existenze ultra and enjoying it every bit.
Will step more carefully now on, using above as experience. Thanks all. This thread is closed until i have another problem

[q] ota update when rooted

Greetings to all,
Before my question, I am currently running at this specification:
Model C903
Android version : 4.2.2
Firmware : .257
Rooted? : YES
No CWM installed. Stock kernel and Rom.
I would like to ask if it's okay to update OTA while I'm rooted? the reason I didn't update before is because I might lose my game data/progress if I was just going to flash a fresh stock ROM, update and root - restore the game data using TBP.
I once experienced it that restoring app data from different android version isn't possible, got nothing to do but stopped playing that game.
Now, i guess my software version is really outdated so I am asking here for some help.I am thinking that updating OTA will best ensure my game data but i do not know if there's any side effect in updating OTA while being rooted because I cannot afford to re-flash a fresh FW atm.
Is there any way to unroot? or any other solution guys? Thank you in advance.

Anyone?

The question is: do you want to keep your root after the update? If so, OTA from 257 to the latest firmware version won't keep root. You're better off using the [NUT]'s method here: http://forum.xda-developers.com/showthread.php?t=2628185

Thanks for your response, i dont mind getting rooted after the update, as long as there will be no BUGs after that? Yup NUT's rom is pretty cool, however, im concerned about my data right now and I have a little time to do that atm.

His method will not wipe your data, as long as you choose not to do so when using Flashtool.

The apps will remain if you use Pccompanion but you will loose root. However if you use flashtool there is an option to wipe everything, so you can choose if want to leave the apps or remove them.

The best way is by using "SEUS"...Cleanest and best method ever existed...
It wipes out everything!

My sp stuck in boot loop
Hi guys, Please HELP!!!
So I rooted my phone a while ago and it was all fine until yesterday, when I changed the boot animation, stupidly, I forgot to rename the original boot animation zip so when I downloaded the new one, They both had the same name. Not realising this I went ahead and restarted the phone and I'm guessing the system did not know which one to use and is stuck on bootloop, is there any way out?

Heya there!
Did you make a backup of your ROM in a recovery? If so, boot into recovery and restore your backup.
If you don't have a recovery and didn't make a backup,the only way out would be to flash stock ftf file for your specific phone (C530X, area/region) using Flashtool by androxyde. THIS METHOD WILL WIPE EVERYTHING except your external SD

Hi, if they both had the same name then the system would've simply overwritten the old one and put the new one in. If you have a backup of your rom you could extract the original bootanimation and use a flash-able zip with your original boot animation. Or just download another bootanimation that works with sp and then just flash it.

Hi,
I own a C5303 and running on firmware 12.1.A.1.205. I would like to know what are the tools I need to root. I am aware I need to unlock the bootloader as I have some experience rooting other android devices. I have downloaded flash tool but I couldnt somehow get into the bootloader. I would like some suggestions for what firmware to use and the process to root. I did not get the latest OTA update(12.1.A.1.207) from my carrier (Virgin Mobile Australia). I have also experienced the annoying screen brightness changing from time to time.

check first that unlocking the BL is possible
Do this by going into the stock dialler entering *#*#7378423#*#* a window will open
Proceed to press service info then configuration and you can find out under rooting status if it says no your BL cannot yet be unlocked (like me). if yes you can unlock
Phone must be powered down to continue
To enter fast boot to unlock the BL press volume up then while holding it plug in the USB into your device if done correctly greenlight will appear ( do this when flash tool tells you to connect your device.) Process will ERASE internal storage so backup and DRM keys will be lost so backup those as well think there's a thread for that somewhere. Good luck phone will reboot afterwards

Hey, I want to change my GApps package which has been giving me FC's since day one. It's been a month now, so I don't wanna wipe and start anew. Any Ideas??[emoji4]

I'm afraid the only way that I know of is to wipe and start over.

Yes.
Something not mentioned in the thread was if you use flashtool to unlock your boot loader (by pressing "BLU", " Unlock Boot loader" then enter the unlock code) it is much easier and will automatically backup ur DRM keys so if you want to relock (BLU, Unlock Boot loader, there will be a new button saying relock boot loader and the unlock code will still be entered) the DRM keys will be automatically restored.
This is for some versions of Flashtool by Androxyde... Not sure if its for all.
