So, i've tried to unlock bootloader using this guide: http://forum.xda-developers.com/showthread.php?t=1254225
The first part (up to step 5c) ha gone really smoothly, without any complications.
However when i tried to connect phone to Flashtool all i got was "Device connected with USB debugging off". So then i decided to do the dumbest thing (now i know that) i could do: reboot my phone. Now it's not powering on, so I'm assuming it's bricked.
So my questions:
1. Is it bricked beyond all repair, and i cannot do anything about it, or perhaps there is still some hope left for me?
2. If it's bricked, will service be able to help me? And if yes then how much approximetly would they charge me for that (I'm assuming that my warranty is void because of my attempts)?

Answers:
1. A cellphone technician with a JTAG/RIFF BOX tool can fix your phone, or the alternative is by replacing the motherboard of your device, you cannot fix at home, that is for sure not unless you have this devices and know how to use it.
2. As for the warranty, just play dumb and say that you dont know what happen to your device. Your warranty is safe as long as they didnt find out that you have mess up the bootlader, IDK much about this, but for me this work.
It happens that, x8 that has been manufactured in 11w26 to 11w37 is problematic and 11w38 beyond is surely bricked if tried to unlock the bootlader. The issue is, they have fixed the security loophole in the bootloader in the later releases. I have 11w44 x8 black that has been hard bricked a few days ago, and I just play dumb in the service center, and they didnt asked anything, it has been covered in the warranty, so free service.

There is nothing wrong with the procedures that has been provided by the guide, its just that there is something wrong with your phone, most probably youre x8's mfc is 11w38 or up, "remove your battery, then look for the e.g. 11w38 something like that in the back of your phone, 11 is year 38 is week that it has been manufactured."

I just hardbricked my friend's phone, it was a 11w41, so he is going to claim his warranty tomorrow, do you know if there is some way to unlock bootloader to a 11w41+???
So basically someone (I don't know who, I was drunk, I thought it was a joke but no one has come forward) has set a pin on my phone and I can no longer use the thing.
I just want to be able to make phone calls again.
Is there anyway to factory reset my Sony Xperia Z1f without knowing the pin? What are my options basically?
Thanks,
Alex.
Go to Sony Service or the Store where you bought it, they will reset your phone a think for free.

I was hoping to be able to use it this weekend *sigh*
Do I need the receipt/box or something? I bought it from a small importing company who have told me I will need to mail the thing to Sony at my own expense as the nearest service center is a 10 hour drive.
So there is literally no way for me to unlock my phone short of how ever many weeks it takes Sony to mail it back to me?
It's like the shop where I bought mine, they said I got Manufacturer Warranty so I will have to send the phone to Sony, but actually when I call them they will do this for me. Go there and ask them or call them.
Factory Reset the device with PC Companion.
It doesn't ask for a PIN when I just tried now.. I needed to FR mine for the 4.3 update, so I tested it for you

Sorry what is PC Companion? Can you please post a little more info, would be super grateful. I have not been active on these forums in quite some time and am out of the loop haha
Also, I tried following this guide...
http://unlockbootloader.sonymobile.com/instructions
But I can't access the service menu on my phone from the emergency dialer like many YouTube videos show.
Why might this be?
Pc companion is a program for your Pc where u connect your phone and you can do loads of things like reset update etc...is made by Sony so just do a lil Google search and download it... Or go on Sony website

Ok I got PC Companion and figured it out and have updated my phones software to the latest version.
But now after reading through these forums I think I would like to flash a custom ROM, however looking in the service menu my phone says that bootloader unlock is not allowed.
Is there someway to still unlock my bootloader and flash a custom rom?

No, if Unlock Bootloader Allowed say NO you can't unlock it, but you can flash custom roms with stock kernels and also root your phone. Unlock Bootlader is needed to flash custom kernels only.
Hi there
I am encountering an issue with my Sony Xperia T (FW: 9.1.A.1.141) which I am certain can be resolved with the correct tools and knowhow, but having spent the last week following what feels like every related link on the internet, I am no further forward - sleeping badly as a result - and very much in need of some help.
I'd prefer to avoid a torrent of potential fixes that I may already have tried at length so please forgive me if I go into too much detail. I just want to be very clear exactly where I am and what I have done so far to try and fix the issue. My PC is running Windows 7 64-bit (no issues).
This is my first proper smartphone so after a few months getting to grips with the underlying nature of the Android OS, I decided it was now time to root the phone and try out different ROMs etc. After reading what I could about the process, I finally used DooMLoRD's Easy Rooting Toolkit 17 (For Sony Xperia Devices) and was amazed by how easy it was to unroot my device. After installing Titanium Backup and fully backing up my files, I then installed ClockWorkMod Recovery 6.0.4.6 (For Sony Xperia Devices), and was able to boot into the recovery environment without issue (I also made an additional backup of the system at this point). So far, so good.
I then copied two ROMS to my SD card - Android 4.4.2 (KitKat) For Sony Xperia T (AOKP Build) & CyanogenMod 11.20140127 (Nightly) For Sony Xperia T - and tried to flash the CyanogenMod ROM from within the ClockWorkMod Recovery Environment, however I received a Status 7 Error, preventing me from flashing the ROM, then tried the same with Android 4.4.2 (KitKat) ROM, but again I received a Status 7 Error. As I attempted to leave the recovery environment to research the Status 7 Error, the program flashed a popup saying the phone was not rooted and would I like to root it. At this point, I assumed I had lost root as a result of the Status 7 Error, but didn't want to make any more changes, so chose no to the root option and restarted my Xperia T.
At this point the Sony logo went into a loop and despite restarting the phone using power and volume up many times, I was unable to boot back into the ClockWorkMod Recovery Environment nor connect the phone to my PC, although I could see the drivers appear for a few seconds in Windows before disappearing. It took me a good couple of days to realise that I had to fully charge my phone, so when I began the operation again with a fully charged phone I was able to update the driver in Device Manager from Sony Ericsson Seehcri Control Device (yellow exclamation mark) to Sony ADB Device (although the Sony Ericsson Seehcri Control Device with exclamation mark later returned so I am unable to assess how successful this actually was).
From here, I tried to update the phone using the already installed and up to date PC Companion, but the phone will not connect in flash mode, so it is not possible to connect the phone. I also tried the latest Sony Update Service (2.13.4.16), then Sony Emma Flash Tool (For Sony Xperia Devices), but none of these recognise the phone because I cannot get the phone into flash mode. Using the Android Flash Tool 0.9.13.0 (For Sony Xperia Devices), I am able to connect to the phone in fastboot mode, but when I try to install a stock kernel or any other variant, the Flash Tool states that I can't make any changes because the phone is not rooted.
Thinking I could root my phone again with DooMLoRD's Easy Rooting Toolkit 17, this time it no longer works, I assume because my phone cannot enter flash mode, even though it is recognised in Android Flash Tool 0.9.13.0 in fastboot mode (blue light).
Now, it is conceivable since my phone is no longer rooted that I may well be able to have my phone fixed under warranty and returned to me, however I would thereafter be scared to try and install a custom ROM, and would never really feel comfortable with the phone again, so I would much prefer to learn how to fix the problem myself. I am convinced the phone is salvageable because I have no issue recharging the phone, the screen is lighting up to display the Sony logo without issue and I am able to connect to my PC so that Sony ADB Device is recognised in Device Manager and via the Android Flash Tool 0.9.13.0, but can make no other changes.
My suspicion is that it has something to do with the ADB drivers, (which I linked to my Android Developer Tools Bundle 20131030 64-bit via the Windows Environment Variables), since no devices are recognised when I connect the phone and run the ADB Devices command in the Windows Command Prompt even when Windows is otherwise able to identify the device in Device Manager.
If anyone would be willing to talk me through this, I would be most grateful and would follow up all advice up so this information might be useful to others in the future as I can't see this being an isolated case. Likewise, if I am simply wasting my time and need to get the phone replaced or repaired, at least it would be good to know that I have exhausted all other options.
FYI Prior to the soft brick, I had USB debugging enabled and was in Mass Storage Mode (since this was more stable than Media Transfer Mode).
Hi. I don't see any mention of bootloader status. Did you go through the process of unlocking your bootloader? Or have you checked to see if your phone is "bootloader unlock allowed: yes"? The reason I ask is because the 2 roms you want to try seem to be AOSP-based / Cyanogen, which run on custom kernels. If your bootloader is locked, you are not allowed to flash custom kernels. That might explain the failure code you say in CWM - or it might not (since my bootloader cannot be unlocked, I don't have much experience with those kinds of ROMs).
Moving on to the recovery you flashed - Which recovery did you install? I have been reading that Clockworkmod recovery (v9) is quite buggy. You can get v8 in this thread: http://forum.xda-developers.com/showthread.php?t=2609997
The peeps in this forum are pretty good problem solvers (and creators ;D) - we'll get you going again hopefully!
is your bootloader unlocked dude?i mean if you have a locked bootlader you are not supposed to install custom roms. and if your boot loader is unlocked sony update engine and pc companion wont solve the issue. you have to try with flashtool .firstly you gotta install the flashtool drivers fot xt .and then run flashtool x64. hold the vol down button and connect it using usb. i had this problem many times. and that above procedure may solve your issue
Hi there
First of all thank you so much for replying. These forums are quite daunting at times and it is good to know someone with some clout is listening. Apologies again for going into yet more detail, but it should help me reach a resolution sooner rather than later.
As re the bootloader, I was under the impression that DooMLoRD's Easy Rooting Toolkit 17 would root my stock Xperia T while leaving the bootloader untouched - that is to say locked (as far as I am aware) - should I wish to revert the rooting process at a later date. Now, I obviously lost root somewhere along the line, but has the bootloader also been changed to unlocked? I don't know, but I wouldn't imagine so, so I can only assume it is still locked.
I have recharged my phone ready to make some fresh attempts at this, but to confirm the current state of my Windows 7 connection, I can only connect to the PC in fastboot (with the blue light turned on after connecting to the machine while pressing volume down). There is definitely an issue with some aspect of the drivers since the Sony ADB Device is recognised as working in Device Manager as soon as I connect the phone, however the bothersome Sony Ericsson Seehcri Control Device is also present with a yellow exclamation mark indicating a problem.
Now, whether this is actually affecting my use of the Android Flash Tool 0.9.13.0 and the other flash tools, I can't actually say. When I open the Android Flash Tool with the phone connected, the two options available to me are flashmode or fast boot mode. When I try to use the flashmode with the (as far as I am aware) Xperia T stock firmware LT30P_9.1.A.1.141_PL.ftf, I simply cannot connect in flashmode when prompted. I am asked to remove the phone then reattach it, but no green light ever shows indicating flashmode, only the blue light indicating fast boot mode. When I try to use fast boot mode on the other hand, firstly I am not sure which of the various methods to use - I have of course tried them all, and also I should say both the 32-bit and 64-bit versions of the Flash Tool - but when I do, I am always told that the device needs to be rooted first.
Now, this may have something to do with the kernels/firmware/ROMs that I am using (there's no question all the variations confuse me a little) as I assumed it simply wasn't possible to flash via fastboot yet further reading suggests that it should be possible to flash a stock kernel without root access. The kernels/firmware I have tried are: stock-7.0.A.3.223-twrp-2.3.3.0.elf; 15102012.img; Sony Xperia T Kernel (Stock) With CWM602; Sony Xperia T Kernel (Stock) With TWRP2500. So perhaps I am not using the correct firmware or kernel (I would like to try the LT30P_9.1.A.1.141_PL.ftf, but cannot see an option to do so via fast boot mode). If this is the case and I am able to identify the correct kernel, then perhaps this "device must be rooted first" notification would no longer happen and the state of the ADB drivers would be largely irrelevant.
On the other hand if the flash tool in fast boot mode is always going to ask me to root first, wouldn't it make more sense to focus my attention on being able to connect to DooMLoRD's Easy Rooting Toolkit 17 in order to root the device so I can then use the Flash Tool in fast boot mode without any further issues. But that being the case, perhaps I should focus on working out what is happening with the problem Sony Ericsson Seehcri Control Device in Device Manager. Perhaps when that is resolved I will be able to connect to any of the available flash tools.
As far as ROMs and Recovery Environments are concerned, I truly appreciate your advice - and believe me when I resolve this problem I will be sure to run through my rooting plans BEFORE executing them on these very forums - but for now I need to focus on flashing the phone back to stock or somehow connecting the phone to one of the Sony Flash Tools.
Thanks again for your patience and assistance so far and I look forward any more ideas now I have provided a bit more detail.
My sanity hangs in the balance!
BTW, I imagine you are both quite right about what went went wrong in the first instance - I did not appreciate you couldn't flash any ROM once the Xperia T had been rooted. Again, when I resolve this issue, I will describe my exact plans before proceeding. Thanks for clearing that up. I'm learning all the time.

Try unlocking bootloader, fastboot flashing boot.img of the rom you want. (before hand get the rom you want on sd or something) And then you should flash without error.

No - the bootloader unlock is a whole process in itself. DoomLord's (fantastic) root kit will root your phone - meaning, it will root your phone's current system, to allow read/write access to the system's files. When you unlock the bootloader, that allows you to write to partitions (kernel aka boot, radio/baseband? etc.)
I have recharged my phone ready to make some fresh attempts at this, but to confirm the current state of my Windows 7 connection, I can only connect to the PC in fastboot (with the blue light turned on after connecting to the machine while pressing volume down).

Since right now, what you need to be able to do is flash a stock FTF (to get your phone working again), make sure your phone is disconnected from the PC. Drivers --- all you should need is Sony PC Companion installed (which installs base drivers for the phone), and Flashtool (http://forum.xda-developers.com/showthread.php?t=1943886). After you install Flashtool, you will need to go into its folder - inside of there is a "drivers" folder. go in there and run the EXE. On the left side, make sure to click/check the driver for your phone (xperia T or TL or LT30p or whatever), plus the Fastboot driver, plus the Flashmode driver. Let it do the install. **NOTE** i dont know if Win7 has "driver signature enforcement" - if you notice the drivers are failing to install, that could be why. Look into how to temporarily disable driver signature enforcement and try these 3 drivers again. You will need them!!
Now, whether this is actually affecting my use of the Android Flash Tool 0.9.13.0 and the other flash tools, I can't actually say. When I open the Android Flash Tool with the phone connected, the two options available to me are flashmode or fast boot mode.

Stop here for a second - For the purpose of flashing an FTF (i.e. getting your phone back to working state), do not connect the phone yet.
When I try to use the flashmode with the (as far as I am aware) Xperia T stock firmware LT30P_9.1.A.1.141_PL.ftf, I simply cannot connect in flashmode when prompted. I am asked to remove the phone then reattach it, but no green light ever shows indicating flashmode, only the blue light indicating fast boot mode.

When using Flashmode, don't connect the phone at all - Choose flashmode, then choose the FTF, then wait for it to process the files, then it will pop up to tell you when to connect the phone. And this is very important - make sure the phone is fully OFF, then, hold the VOLDOWN button, then plug the usb cable in - when you see Flashmode start moving along, you can let go of the VOLDOWN button... and put the phone down gently .. you dont want to distrub this delicate process .
When I try to use fast boot mode on the other hand, firstly I am not sure which of the various methods to use - I have of course tried them all, and also I should say both the 32-bit and 64-bit versions of the Flash Tool - but when I do, I am always told that the device needs to be rooted first.

This may all depend on your bootloader - if your bootloader is locked, you likely cannot get the phone into Fastboot mode.
Now, this may have something to do with the kernels/firmware/ROMs that I am using (there's no question all the variations confuse me a little) as I assumed it simply wasn't possible to flash via fastboot yet further reading suggests that it should be possible to flash a stock kernel without root access.
Click to expand...
Click to collapse
Right - flashing via fastboot may not be possible right now if your bootloader is locked.
The kernels/firmware I have tried are: stock-7.0.A.3.223-twrp-2.3.3.0.elf; 15102012.img; Sony Xperia T Kernel (Stock) With CWM602; Sony Xperia T Kernel (Stock) With TWRP2500. So perhaps I am not using the correct firmware or kernel (I would like to try the LT30P_9.1.A.1.141_PL.ftf, but cannot see an option to do so via fast boot mode). If this is the case and I am able to identify the correct kernel, then perhaps this "device must be rooted first" notification would no longer happen and the state of the ADB drivers would be largely irrelevant.

Yes - let's skip the kernels for now - and get you flashing a fresh FTF so you can start over. I suggest that once the FTF is flashed, and the phone can boot normally, you dial the Service Menu number and look to see if your phone has "Bootloader Unlock Allowed: Yes" or "Bootloader Unlock Allowed: No". -If it says NO, it means NO! There is currently (as of Feb3/2014) no way to get around this. This means your bootloader cannot be unlocked, which means no custom kernels, and no fastboot! Custom ROMS can still be flashed - just those that are Locked Bootloader-friendly (meaning, the custom rom operates just fine/is based on the Stock kernel - whatever version is preferred will be mentioned in the dev's first post of the thread). There are a few.. like XperimenT and T-Hybrid. I like those.
I'm going to be safe and assume yours says No (like mine, because everyone should suffer with me!! ) You can then ROOT the system like you did, then install CWM Recovery for locked bootloaders (v8!! dont use v9 for now), then you can flash a rom or do whatever. If the custom rom you're installing is based on a stock kernel whose version number is different from your phone's base, then you may be able to find kernel zips that are flashable via CWM - since they are stock kernels, the flash will be allowed because they are signed or whatever. Example: Since you're going for LT30p .141 FTF, you're on the 141 kernel. If the rom you're installing says it recommends the .145 kernel, find the LT30P .145 kernel zip. You can flash that right after flashing the ROM. I think that the 141/145 kernels are similar to each other so in this case, you may not even have to flash from 141 to 145. But you will - because you will become addicted to flashing like the rest of us and you will want to observe/compare how the ROM behaves on each.
On the other hand if the flash tool in fast boot mode is always going to ask me to root first, wouldn't it make more sense to focus my attention on being able to connect to DooMLoRD's Easy Rooting Toolkit 17 in order to root the device so I can then use the Flash Tool in fast boot mode without any further issues.

I think what it's really asking you is to Unlock Your Bootloader. Unlocking the bootloader is kind of considered a global root (because it allows writing to any partition on the phone.
But that being the case, perhaps I should focus on working out what is happening with the problem Sony Ericsson Seehcri Control Device in Device Manager. Perhaps when that is resolved I will be able to connect to any of the available flash tools.
Click to expand...
Click to collapse
Yes - hopefully above we have tackled that.
As far as ROMs and Recovery Environments are concerned, I truly appreciate your advice - and believe me when I resolve this problem I will be sure to run through my rooting plans BEFORE executing them on these very forums - but for now I need to focus on flashing the phone back to stock or somehow connecting the phone to one of the Sony Flash Tools.
Thanks again for your patience and assistance so far and I look forward any more ideas now I have provided a bit more detail.
My sanity hangs in the balance!

Agreed!! Good luck!
Thanks for the considered responses. hhamzah49, I have tried to use the bootloader unlock in the flash tool, but it simply waits for me to connect in flash mode, which is what I am unable to do. There is not even an opportunity of using a SD card since I cannot start the phone either normally or in a recovery environment.
LaZiODROID, you're the man for going into so much detail, and yes I am looking forward to trying out loads of ROMs if possible, however I can't consider such luxuries until I've flashed the phone back to stock! It seems the bootloader probably has a lot to do with it, and I wish I could confirm one way or another if it is locked or not, but I don't see a way to do that in the phone's current state. I bought it from Amazon UK in October or thereabouts, so perhaps that might give you a clue - I would assume it is locked for now, but happy to try the process working on the assumption that it is unlocked if that is likely to help.
I am already using the Flash Tool you suggested and have OKed the drivers signature on Windows 7. I understand about not connecting the phone prior to preparing the flash tool (in flashmode) - and making sure it is fully off by pressing power and volume down until I feel the three vibrations indicating the phone is fully off - but all this seems to be immaterial as I am never able to connect in flash mode. Only the blue light ever appears, never the green one.
You say it is likely that I will not be able to connect the phone in fast boot mode because my bootloader is locked, however I am ONLY able to connect in fast boot mode so if I am not able to flash via fast boot, I am not sure what other course of action to take.
I think I understand now about the unlocked bootloader and having to source suitable ROMs when the time comes, but not quite there yet.
I have uploaded several images of my current connection via Command Prompt, Device Manager, Android Flash Tool 0.9.13.0 & DooMLoRD's Easy Rooting Toolkit 17. I also noticed that when I start DooMLoRD's Easy Rooting Toolkit 17 with no ADB drivers running in Windows Task Manager Processes, two instances of the ADB driver appear, each leading back to DooMLoRD's Easy Rooting Toolkit 17 and each a slightly different size. When I try to run the Rooting Toolkit, the command prompt simply says "daemon started successfully", but nothing happens after this. If I kill one of the two ADB processes, this seems to start the program off, but to no avail since "device not found" is displayed repeatedly.
Anyway, my comatose phone and I remain on standby ready to try whatever it takes.

Detail is always good - much better than a "i rooted my phone and now it doesn't work" post. I agree, information is in many different places - very easy for that to happen.
Yes - that is, if your bootloader was Locked when you started this whole adventure. - Maybe but maybe not!, No - the bootloader unlock is a whole process in itself. DoomLord's (fantastic) root kit will root your phone - meaning, it will root your phone's current system, to allow read/write access to the system's files. When you unlock the bootloader, that allows you to write to partitions (kernel aka boot, radio/baseband? etc.)
Since right now, what you need to be able to do is flash a stock FTF (to get your phone working again), make sure your phone is disconnected from the PC. Drivers --- all you should need is Sony PC Companion installed (which installs base drivers for the phone), and Flashtool (http://forum.xda-developers.com/showthread.php?t=1943886). After you install Flashtool, you will need to go into its folder - inside of there is a "drivers" folder. go in there and run the EXE. On the left side, make sure to click/check the driver for your phone (xperia T or TL or LT30p or whatever), plus the Fastboot driver, plus the Flashmode driver. Let it do the install. **NOTE** i dont know if Win7 has "driver signature enforcement" - if you notice the drivers are failing to install, that could be why. Look into how to temporarily disable driver signature enforcement and try these 3 drivers again. You will need them!!
Stop here for a second - For the purpose of flashing an FTF (i.e. getting your phone back to working state), do not connect the phone yet.
When using Flashmode, don't connect the phone at all - Choose flashmode, then choose the FTF, then wait for it to process the files, then it will pop up to tell you when to connect the phone. And this is very important - make sure the phone is fully OFF, then, hold the VOLDOWN button, then plug the usb cable in - when you see Flashmode start moving along, you can let go of the VOLDOWN button... and put the phone down gently .. you dont want to distrub this delicate process .
This may all depend on your bootloader - if your bootloader is locked, you likely cannot get the phone into Fastboot mode.
Right - flashing via fastboot may not be possible right now if your bootloader is locked.

try to do a hard reset; (while NOT connected via usb or something) hold power+vol up, it will vibrate 1 time, and then 3 times quick. After that try to connect the usb (NOT while pressing any buttons) and press vol down+power
That should connect it into flashmode.

OK, I'm totally aware that this seems to be the main clincher, if I can somehow get it into flash mode (with green light), but I have tried connecting it pressing every combination of button I can think of, but it only ever connects in fast boot (with blue light). I'm just gonna grab a bite just now, but will try this some more right after and let you know (turning the phone off with one vibration, then three, up and down buttons etc). Thanks again for now.

Since your phone doesn't boot into a system, I'm not sure if DoomLord's rooting kit will help you. What is there to root? There's no Android system running yet for it to root (right?).
Great news
You beautiful, beautiful people!
I managed to get the phone into flash mode by following your exact instructions to turn the phone fully off when disconnected from the PC (by pressing power & volume up until I felt three vibrations following a single vibration), then connected the phone again WITHOUT pressing the volume down button (as I had always been doing before), then, after the red light came on and the Sony logo appeared, pressing power & volume up again until suddenly the beautiful green light lit up and I was able to flash the phone back to stock firmware (LT30P_9.1.A.1.141_PL.ftf). I lost flashmode the first time because I was so shocked, and there doesn't seem to be time to hang around, but the second time I connected it again the firmware flashed immediately, fairly quickly and without any issues and I am now looking at my freshly started phone and the virgin Sony Android screen.
I have to say this process is unquestionably difficult to explain over the internet, probably because there is no universal implementation of the buttons, but at least once you know how, you are sorted for future problems (of this type at least).
I swear to god, I feel about a stone lighter as this was really hanging over me - not only am I too skint to be worrying about dead phones and warranty issues, but now I feel more secure testing things out, and might even be able to help others in the same predicament in future. I'm not sure if all the excessive detail was warranted, but better to err on the side of caution as a general principle I believe.
My sincere thanks to everyone for helping me out! You have given me a great introduction to the site and I look forward to any and all future communications.
Sadly, I have a pile of crap to attend to, now I know the phone is working, so I will regather my strength for a fresh attempt at rooting the phone (with DooMLoRD Easy Rooting Toolkit 18 For Sony Xperia Devices), installing a recovery environment (CWM v8 as opposed to v9), then flashing a suitable ROM tomorrow evening. I checked my service menu and it states, "Rooting status: Bootloader unlock allowed: Yes," which I trust opens my options a bit more. The two ROMs I am initially wishing to try are CyanogenMod and KitKat, but would be nice to know I could try others without more problems. I am now also aware to backup the TA Partition via the Android Flash Tool 0.9.13.0 before rooting the phone and assume I should hold off reinstalling my Titanium Backups until I am happy with a particular ROM.
I expect this isn't the place to go over these things (although I am quite happy to do so), so I will start a new thread tomorrow to go over my best plan of action.
Thanks again, and I hope this helps out someone else in the same position!

Thank you, LaZiODROID. You've been more than helpful so I trust you don't mind my quickly confirming what I now understand about the bootloader now you have so succinctly brought it to my attention.
I previously hadn't taken into account the state of the bootloader when I tried to flash a ROM, so my failure (Status 7 Error) probably suggests that the bootloader must currently be locked, although it is possible to unlock it on my particular handset (but not yours), is that correct?
All I knew when I used Doomlord's Rooting Kit was that the bootloader would not be affected thus preserving my warranty status, however it would be advisable for me to unlock the bootloader using the Android Flash Tool 0.9.13.0 so I can install custom ROMs without having to worry about special packages like XperimenT & T-Hybrid, is that also correct?
The only final query I have is, if I do unlock the bootloader (using the Android Flash Tool) in order to flash custom ROMs, can I then lock it again for the purposes of my warranty?
I shall assume the bootloader should be unlocked AFTER rooting the device, but BEFORE installing the CWM Recovery Environment.
Thanks again! I will rest easier tonight.
I think hhamzah49 is the hero who got you going with that nice trick (to get you into flashmode)! I guess it turned out that you didn't have driver issues after all.

There is also the official Sony method of unlocking your bootloader (see the all-in-one thread). Re: ROMS...

You just have more ROM selection with an unlocked bootloader because you can use the kernels that ROMS like Cyaongen needs.

Im really sorry for posting this question, but im really really noob at this.
I Have a Xperia SP C5303 with stock Android 4.3 and 12.1.A.1.205 and bootloader locked.
My phone is getting extremely slow at everthing, all applications take huge time to load, sometimes even crash, i cleared all cache on applications, even deleted all my messages (1.5years) and nothing worked. Started in safe mode and its pretty fast.
Im tempted to update my SP to a custom rom 4.4.x or even 5.xx .....but i really dont know nothing about it. Dont know how should i proceed and what steps should i take to backup and prevent any problem in case of something goes wrong.
I already used the "towelroot" and installed SuperSU from google playstore and it says its rooted, but already read somewhere that towelroot doesnt actually really root.
I really really appreciate a huge help on this if possible.
Thank you very much.

I think unlocking your bootloader resets everything so backup your apps for re installation once your are done.
I unlocked my bootloader the good old fashioned way via fastboot :
1 - Check if unlocking possible by typing *#*#7378423#*#* in the dialer and going into Service info > Configuration.
2 - If it says something like Bootloader unlock allowed - Yes then its unlockable. If its already unlocked, it will say something along those line as well.
If neither option appears then it isn't unlockable.
3 - Get the unlock code from Sony after filling the necessary details along with the IMEI no. of the phone.
3 - Open command prompt in the adb & flashboot folder by holding Shift + right click and selecting the "open command window here" option.
4 - Type fastboot.exe -i 0x0fce getvar version to check if device is connected properly.
5 - Type fastboot.exe -i 0x0fce oem unlock 0xKEY. Repalce KEY with the code that was received from Sony and hit Enter.
Alternatively the BLU option in FlashTool can be used to simplify things as it automates most of the above procedure. It can also be used to relock your bootloader.
There's also a new app called Kingo SONY Bootloader Unlock that apparently unlocks your bootloader with one click. Check it out.
I was doing that at the moment. Im using Fastboot also ....since i didnt find other ways
Already made a copy of everthing i can remember and used Titan backup also.
My phone says "Bootloader unlock allowed : no" , but im still trying doing all the thing....i read somewhere that sometimes works.
At the moment im stuck in connecting the phone in the computer with volume up ...and testing the fastboot getvar version to check if the phone is connected....but stays there....waiting for device...and nothing ...

If it says no then dunno what the chances of success are.
Came across this Youtube tutorial : https://www.youtube.com/watch?v=Li8Eim6gugw
Don't know how legit it is since its been posted a few months back and there are no comments at all so please proceed with caution and of course don't blame me if you brick your device
Also did you try the Kingo unlock app I mentioned?
Nothing works...cant really connect in Fastboot mode...i tried everthing...even in 3 diferent computers...nothing works.
Dont know if "bootloader unlock allowed : no" means that i cannot enter in fastboot mode....or if im doing something wrong...
Just install some 4.4.4 lbl build, for example cm11 by mateo337 is really good and even up-to-date.
You will not be able to unlock the boot loader i had XSP that said no and i was not able to do anything about it.
Dont use 5.x.x builds, they are really outdated and have a lot of bugs.
So, then i suppose the next step its to install a LBL Recovery? So i can boot in recovery to flash the custom rom....right?

No you should still be able to enter fastboot mode. Are you using the latest version of FlashTool and have you installed all 3 required drivers? Does your phone show up in device manager when you connect it in fast boot mode?
I am not sure abt the last 2 procedures I posted but the first 2 require your phone to boot into fastboot and stay there till the job's done.

Yeah. Since your phone's rooted now, you can follow a LBL procedure for flashing a custom recovery to allow you to install custom ROMs.
