[q] bootloader wth? - XPERIA X8 Q&A, Help & Troubleshooting

Hello guys, I've been searching on xda-forums and I didn't found anything so here is the noob question.
- What is bootloader and what will I gain by unlocking this?
- I've got "11W22" Black x8 with cypress, so what are the risk of my phone? (I mean, I will install it, loose waranty, but what are disadvantages?)
- What are "all" the advantages of unlocking bootloader?
- What are the characteristic of kernels (alfs, nAa)(pros and cons) and what are battery life consumption?
I see most of you here using custom kernels and all devs are making ROMs for custom kernels.
The most important things for me are: battery life (need 2-3 days with normal use), stability and fullworking ROM (like stock one).
Can you help me?

- Think of bootloader as the BIOS of your PC.
- You have to unlock bootloader to install custom kernels
- The principal advantage of custom kernel is better performance: you can set swap, overclock, without having to patch modules, has better 3D librarys, etc.
- Since you have a X8, run S1 Tool and verify certificate, to see how to unlock.
- Battery life depends on which rom, how apps you have installed, etc. Dont expect much, cause after all, we have a smartphone (i guess you sleep every night right? so why not left it charging?)
- The main difference between Alfs and nAa is the support of ROMS
nAa = MiniCM based ROMs
Alfs = GDX based ROMs
- Least but not last, you can re-lock your bootloader

Thanks man, really what I needed.
I've got another questions to you:
1 - With unlocked bootloader, can I get back to Stock ROM by using SE application? (In case if anything someday gets ugly and I could need to "reset" everything and start again)
2 - Battery - I know that it depends on ROM and I shall recharge it every day, this is what I'm doing, but with custom kernels the battery improves or gets worse? Or stays the same?
3 - If unlock bootloader is that good, why relocking it?

1. Yes you can go back. Just use PC Companion, it restore stock kernel and ROM, and then you relock your bootloader.
2. I think that stays the same or gets better. You should consider that stock is Android 2.1 and the most of ROMs are 2.3. More recurses, a little bit more battery.
3. I dont know, but I guess if you relock your bootloader, you still have the warranty, in case that any hardware fails. (verify this with someone more pro-user)
Sorry for my english errors, still learning.

I'm using nAa + MiniCM and my battery is dropping 5% every 8-9 hrs. But i have a weak signal (consumes more battery), and 3G, Wifi disable.

I recently unlocked my bootloader succesfully according to this guide.
Then i installed a Kernel (LinuxDX) that bricked my phone and had to restore with Sony Erricson Update Service.
I am using GingerDX now and my log from s1tool is this:

I know that this RUNNING S1_EROM VER "r8A029" has an "r" that means that my bootloader is unlocked but i want to be sure that i can install another kernel without bricking my phone again.
So, can i install safely another kernel ?
Sorry for my english and my noobness i am new here ...

Yes, you can safely flash another kernel.
If you want to stay with GingerDX you can switch to alfsamsung's Alfs kernel - don't forget to flash the vold update in CWM or you will have problems mounting the SD.
If you want to change to nobodyAtall's nAa kernel you also need to change to the MiniCM7 2.1.9 ROM - GingerDX does NOT work on nAa's kernel. This means you first flash the kernel, reboot, enter CWM right away and flash the ROM (you hopefully copied onto the SD card beforehand).

While i was waiting for a reply i look around some kernels and i must say i got pretty much confused.
I noticed that most kernels have in common the ext2/3/4 , CPU governon and swap (?).
I cant find infos for these and i dont have a clue of what they are for.
And btw smartass is a CPU governon or something else ?
Thnx for the reply as i cant press thank button yet i think.
Edit: Also any info for what X8Gesture is for ?

You cant use PCC when you have a custom kernel installed, you need to use SEUS which works perfectly and does the same job.

For me, PCC works great with custom kernel. I already repair 2x with no problems.

- Most of kernels have the same features, but supports a different kind of ROMs.
- SmartASS is a CPU Governor: it increase/decrease clock speed of processor when need it. (Google for more info)
- X8Gesture is a module for fake dual touch in Synaptics touchscreen. In most custom kernel, it already implemented.
- Swap is linux virtual memory (Google for info)
- Ext 2/3/4 linux filesystem. You partition your card, and then you can install apps on it.

Umm, you have a dual-sim fake Sensation XL, so probably none of the tools here will work on you, at best you can do all the things by yourself, dev things for it...

Fakes usually have unlocked bootloaders and you most probably can root it using some generic rooting methods, for other device i mean, check any root script for ICS on other devices and try it for yourself, rooting is achievable on fakes.

[Q] Allow unlock bootloader

Hi guys, i have a question, I will go tu buy a XPERIA SP (FACTORY FREE, without any brand), and i want no know if there is a posibblity of they come with ALLOW UNLOCK BOOTLOADER: NO.
Thanks for your answers.
Yes there is the possibility
My phone was like that, I bought it SIM Free and discovered that it showed NO.
After a few mods and rooting attempts, magically it changed to Yes. But remember that you will lose DRM keys, BRAVIA Engine may worke but other GPS functions will stop working forever, right now there's no need to unlock the bootloader. There arent any good kernels/roms...

Simple my friend... It's because i want to enter into program services across the QPST becuase most of the roms are 2G. and i have 4G service. I use to give service as AP to my lappy on the way, so i will need to cook my own CM with the KK and all the KK are working well with ULB, not with LB... (And most of them in 2G only). Or come back again to the 3G Samsungs...
The key is to alow the bootloader unlock to yes to be with Sony. That's the shame... The air supplier gave me this for my job...
The QPST is a very powerfull tool but only works on the SP with unlocked bootloaders. It's not a simple question of to be root or not. It's a question of to take advantage of the services. 3G is slow, 2G it's impossible for me... No way... 4G is the best... 51Mbps is not 1,5 Mbps... The access to the server by remote takes me 1 hour by instalation of the Wimax access with the 2G... With 4G i make only 10 minutes... (Anyway, also has a high cost, but life is too short).
I will have to wait to have some solution for the bootloader permission... That's life...
(But if you find the version with that bug, will help too much).

[Q] Xperia T soft brick - HELP GREATLY APPRECIATED

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.)

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.
Click to expand...
Click to collapse
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.
Click to expand...
Click to collapse
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.

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.

I am not able to understand the words like carpetetas or recueperar? you can take your phone to local service center and ask them to see what is wrong. First take backup of your phone like contacts, sms whatsapp data etc. then visit service center. If everything is okay ( DRM Keys and TA partitions ) they will flash latest 4.4.4
If yiu didnvt unlocked the bootloader then try to install arom for ur region but if u unblocked bootloader i think you have lost ta partition so the imei doesn't show up when u call *06#
I think so too. May be you have unlocked bootloader without backing up TA partition and DRM keys thats why you are not able to upgrade your phone to version 4.3 or 4.4.2 or 4.4.4.
There was same question some time back. Someone unlocked bootloader without backing up and now stuck on 4.1.2. Sony refused to help as he lost warranty of the phone by unlocking. He had no knowledge about unlocking and warranty.

Frankly speaking, I do not understand non-English words that frequently appears in your posts. Having that said, I can pretty much grasp the gist from your posts, although that may not be 100% what you intend to mean. Combined with answers by previous forum members, i offer you suggestions to your problems point by point.
Okay enough of this bull****. First I want to say that if you are unfamiliar with things here on XDA, read the guidelines before you do anything. You probably unlocked the bootloader of your phone, but did not backup anything. In that case, you HAVE to install a kernel everytime you try to switch rom (including a stock-based, or stock for that matter). Your numerous problems above suggests a kernel problem to me. What you do now is to follow UB way to flash a AOSP or whatever rom (not stock) and report if it solved your problems

Amigo antes de flashear una room CM11 o Aosp debo abrir el Bootloader?

Is this weird or normal?

I searched high and low for solution of my problem but i couldnt find the right solution to my problem that's why I'm starting this thread.
Phone- Xperia Sp C5302
Stock Kernel
Rooted
Philz Touch recovery installed
Nandroid backup made using TWRP
Tried to unlock bootloader- Problem starts from here........
Initially phone rebooted normally but couldn't detect sim and signal.
Then phone started rebooting after few minutes . Stay on for a while then reboot again till battery died.
Now battery not charging, phone showing no life, no led, no vol up+power, vol- power , vol up+vol down+power work
Tried everything I know plz help and plz explain slowly and calmly.
THANKS IN ADVANCE.
EDIT:
Used wall charger 2amp for charging left overnight no red led or anything as described in other posts
Connected to laptop left for about 4 hours no nothing.
Tried to connect in fast boot not detected.
Any more ideas guys at least give some pointer for what to do or is my Sp is actually dead ? And I can't restore my backup? Plz guys help
EDIT: Pressed the small button at the back and the phone came back to life YESSSSS........
Now the phone isn't showing imei no. or sim or network. But when restarted it imei and network came back magically. So I thought the problem is solved to confirm it I switched phone off again then switched on then imei and network gone again and also baseband isn't showing too (I'm sorry if it is the same thing I'm a newb to this stuff)
Then again I restarted the phone number it came again. I don't know what to do in this situation. I just wanted to unlock bootloader and install xenon hd rom in my Xperia Sp.

Try flashing stock ftf with Flashtool.
If the problem gets solved, then start with the new ROM.

Use the method answered by the previous post. But I will add into that
You can use the flashtool to flashing everything stock but please dont flash System and Kernel. If you flashed a custom recovery and want it to stay untick Fotakernel as well.
This should fix your problem without having to deal with the stock ROM.
But if problem persists then I would suggest a complete stock ROM flash.
Huge chance that the process of unlocking your bootloader is faulty. Are you sure that it went without errors? Anyway you might also wanto to try to relock and then unlock the bootloader again
@Zenith I left the phone idle for sometime now it's OK ish . I've made a nandroid backup but can u tell me plz which folder contains imei and other important stuff so I can make a backup of it too.
BTW I think my bootloader is not correctly unlocked coz pc companion is detecting my phone bravia engine is there gracenote is working. But in service menu under configuration I found: Bootloader unlocked: Yes.
Previously it was Bootloader unlock: Yes. So is it unlocked or not if not then how to unlock?
I've followed sony's official unlocking method.

You don't need to backup imei. It will stay the same no matter what ROM you use.
and You can use Titanium Backup to backup all your important apps and data. But do not backup/restore system apps.
and in the service menu;
"Bootloader Unlock allowed - Yes" means that your Bootloader is Locked, and you can unlock it.
"Bootloader Unlocked - Yes" means that your Bootloader is unlocked.
Bravia engine shouldn't work if your BL is unlocked, so something must have gone wrong in the process.
Follow what's said in post #4.
@Zenith Thank you for your wonderful suggestion i will do as u say. bt one big noob ques- Do i have to dload a ftf file to flash to stock cant i use my backup or someyhing from it to restore?
@TechnoSparks yeah i think you are right about my bootloader bt isnt there something to check if BL is unlocked correctly. Btw when i requested to unlock BL in fastboot nothing really happened apart from
<Bootloader > Unlock phone requested
OKAY [15.725s]
finished. total time: 15.725
Then restared approx every 10 min or so till battry went flat and phone being dead untill i reseted it via pin

Yes, you have to download the ftf file.
Use this one.
and don't use the latest version of Flashtool, use the "0.9.18.5" version.
@Zenith Thanks bro bt my model is C5302 will it be compatible?
And i just dloded 0.9.18.6 version. its not latest 0.9.19.0 ver is latest.
So do i have to dload again? (connection limited bandwith n slow speed)
@Zenith Sorry bro for bugging you again n again bt u r the only person who showed some intrest in this post and helping me.
Btw ive founded this"https://drive.google.com/file/d/0B-mh6JO-ztBfaGZ6UE1QanFzRTg/edit?usp=sharing" C5302 Indian generic 12.1.A.1.201 [FTF] Is it better?

You should flash ftf specified for C5302 then.
Download the C5302 variant that you prefer from here.
And try flashing with the Flashtool you have. If it doesn't work properly, then uninstall it, and install the 0.9.18.5 version.
Some members including me faced some problems on the next 2 versions of flashtool. So yeah..

It's okay
And as I have a different model, I can't actually assure you that it works or not.
So try and see what happens.
Thanks bro will surely let u know.

Even you can flash C5303 ftf on C5302. I personally use Singapore variant .207. It has got least bugs and it is fast and much bloatware free.
P.S. Dont flash .201 it has got a lot of bugs.
