hi all,
i have recently aquired Sony Xperie SP C5303, and i now i'm lost since i never had android phone. all i used was various emulators for PC and stuff...
but now there is many stuff to be noisy about. and probably this has been answered many times but please, do me a favor and pretty please answer again if possible.
1. Phone is SIM locked (i'm working on getting unlock code from provider, since i have right to do so, after contract expires..which has)..but is there any way to unlock phone before i get the code? i'm wondering how technitians in local services do that. they ask about 30€ for unlocking device, and i doubt they have acces to provider's unlock code.
2. I tried to flash phone with custom firmware (using flashtool) but it failed on me even though i used right firmware, and phone bricked. however i managed to recover phone with sony PC companion and it now works same as when i got it. Firmware 12. 1. A. 1. 205, android version 4.3. i have no idea why it failed on me during flash. can it be cause phone is no rooted, and have no root support? (whill connect to this on 3.) do i have to root phone before flashing? i would really like to have root access.
3. i was unable to do hard reset of phone with power + volume down button. or any other trick didn't work. i couldn't not enter android recovery options. i followed instruction on how to root my phone on
Code:
developersonymobile(dotcom)/unlockbootloader/unlock-yourboot-loader/
. i entered
Code:
*#*#7378423#*#*
to check if my device is unlockable, it says boot loader unlock allowed : No. Does this mean i won't be able to have root acces on my phone? or i still have to learn difference between terms or what they mean.
also is that really true what they warn about that there is no turning back after i root phone and all. won't just hard reseting phone or repair device with all defaults troubh pc sofware bring back and vipe everything back? how will than service know if phone has been rooted ever?
thank you in advance for all your answers.
"Bootloader unlock allowed : No" <= this means you can't use UBL ROMs or custom kernels.
You can always root and use LBL ROMs though. There are plenty of LBL ROMs out there to try.
You can always un-root your phone. And you can always repair your phone's OS by flashing the Stock ROM via flashtool. Doing so would remove root access as well, no one would know you ever rooted.
Root using towelroot.
Get recoveries by Dssmex.
Then flash LBL ROMs, mods, ports etc. that you want.
and Be careful when you flash anything,
Read the threads, don't try to flash any UBL ROM as it may brick your device.
First thank you for helping.
UBL is unlocked boot loader right? and L is locked. sorry to doubt your last tip but i need to double check was it typo or...? you said don't flash UBL. isnt that supposed to say don't flash LBL. or i have totally got this wrong. maybe i don't know what what's LBL and UBL.
but just to be safe? where can i find stock ROM? i tried official site, they don't let me download firmware manualy. only trough sony PC companion automatic repiar. Which is ok too i guess. else i can download sony flash tool callsed emma, but i cannot get login info since they need about 7 days to approve my registration.
so my first step is to root my phone. ok i will do that. i might do it manualy, not trough application though.
what about sim lock? after i root phone, is there sim unlock command or what? and do i need code...how do you unlock your phone to be able to use other SIM.

Welcome.
And no, I did mean "Don't flash UBL ROMs"
UBL = Unlocked Bootloader
LBL = Locked Bootloader
The ROMs that are made for Unlocked Bootloaders are UBL ROMs.
Unlocked Bootloader users can use both LBL and UBL ROMs.
But since your device's Bootloader cannot be unlocked, you can only use LBL ROMs.
It's written in almost all ROM threads if it's a LBL or an UBL ROM. But if it isn't specified, then be sure it's UBL. (Like all 5.1 ROMs are for UBL)
Download stock ftf from here.
Use Flashtool v0.9.18.5
and I can't say about the last one as I don't use a carrier locked device.
Try and see what happens.
thank you again for reply. you've been very helpfull with all info.

that is exactly from where i got it the first time. also same flashtool version. after i tried to use that firmware, my phone bricked.
even though it's stock ROM, probably cause my phone had locked bootloader (i finally found article on what is bootloader and i got it now).
but after this, i have used sony software to recover my phone and it works again.
now important stuff. so my device's bootloader cannot be unlocked. does that 100% means that i'm stuck with locked bootloader and no way of getting it unlocked.
even on sony offical site there is process tutorial how to unlock bootloader, and it says "if you device isn't listed, than you cannot unlock bootloader".
but it IS listed and I AM able to get the unlock code for it. now i'm confused. can i still do the process showed?
another confusing thing is where i read about bootloader, it says that for to be able to root i need to flash custom ROM, and to do that i need to unlock bootloader.
but you have provided link for "towelroot" which was able to get my phone root acces. is it different from rooting my phone manualy after unlocking bootloader. how did it manage to root it anyway? and with towelroot it still has bootloader locked. actually it says "boot loader unlock allowed: NO!". now begs the question does that mean, not allowed, but i can be unobidient one and still unlock it without clearance, or does it mean .."you're stuck with locked bootloader. deal with it!. if you try to unlock bootloader your phone will brick"!.
i think after i get answer to this, than it would be my last question for this topic
also again, thank you for answering all previous questions...and this one, hopefully

Did you install the drivers properly (Flashmode, fastboot, viskan common) ?
You need to disable driver signature verification before installing drivers if you're on Win 8/8.1/probably 10 too.
And flashtool should work perfectly in both LBL and UBL phones.
You said your service menu says, "Bootloader unlock allowed : No"
Even if you get a BL unlock code you can't unlock it coz it's not allowed.
And by messing with the bootloader or trying to flash UBL ROMs may permanently brick your phone.
And different phones have different rooting processses. Rooting our SP is easier than most other phones by TowelRoot.
And "Bootloader unlock allowed : No" is more like a "You're stuck with locked bootloader. deal with it!. If you try to unlock bootloader your phone will brick!".
And you can still use a lot of LBL ROMs, from 4.3 to 5.0. So don't worry Lol.
Welcome
i did install fastboot and drivers and everything acording to tutorial. i payed attention on par "pay attention to this. be sure to install drivers correctly, lol"
i'm using win 7 64bit sp1. i have disabled UAC. i'm alaways running as admin. as for flashtool. software works perfectly..it just fail flashing.
it goes to part where i need to unplug phone and plug in holding volume something button..it says on poppup. than i plug in phone and it starts flasshing..it goes up to 40% something percent. if finish few files but when it comes to system.(something) i forgot extension, it says failed. flasshing stopped. than after that i can't turn on phone again.
i couldn't untill i recovered via Sony PC companion. i did try to flash it several times with several roms. i think it's cause my provider messed with bootloader. they locked it together with sim. on official sony site. it says:
"Note! Even if your device is listed here, certain releases of the device model may not be supported due to operator restrictions. Please select your device on the Start tab to check if your particular device can be unlocked."
anyway, i even got my provider's firmware trough flashtool download system, got my provider's name and exact same firmware that was installed. it still failed on same file.
than after i recovered i didn't try to flash anymore. i don't even know what's the point, if i can have root access without it.
i'm not so keen on installing other android version, unless this one gives me problem. for that i need to unlcok phone first to be able to even use it or test it so far it's has been t urned off most of the time

I see.. I'm not actually sure why Flashtool isn't working.
Anyways some good 4.4.4 LBL ROMs are 'CM11 by Bagyusz', 'Omni-X by NeildownX', PA etc.
Try them if you want.

I assume you're now on a rooted stock ROM.
Follow this to get recoveries.
Reboot, when you see the Blue LED burn, press vol down to enter TWRP recovery.
can i use cm-11-20150822-UNOFFICIAL with flashtool so i avoid installing recoveris or CWMP?
flashtool worked for me it just gave me an error during flashing one of the files....that might be cause i didn't know difference between LBL roms and UBL roms. maybe problem was incorrect rom type for my phone.
i tried to install recovery tools. and i had some problems...when i swhitched on phone there was no light showdown,,just red led...and after phone entered safe mode. but not in recovery menu.
i sure have no idea what to do...now everything is so strange.
to be honest i'm considering dropping this whole thig of and use stock rom as it is...
it would be cool if there would be automatic debloat application which will remove all bloatware...
or at least bloatware list of apps i can delete manually, without loosing important function on my phone. than i would not need custom rom!

If you're on CM11 by Bagyusz, Open Terminal Emulator and enter the following codes,
su
./system/bin/recovery.sh
^ it will give you access to recovery when you see the red LED while booting.
If you decide to go back to stock, you can freeze/remove these apps.
I made the list when I was on stock. Take a backup before removing them just to be safe.
thank you a lot! this has all been so helpful!

Hi all with request for help,
I am trying to unlock bootloader for 4x. I have created and activated MI-Account, downloaded and installed Unlock tool and set device in fastboot. Device is positively recognized by windows with the command "fastboot devices".
But when I start the unlock tool it checks for permissions and I get the message: "your device is not supported by mi unlock" and then it sends me back to the unlock tool download page instead of to the application page where I can put in my details. Cache of chrome browser emptied various times - no success. It´s catch 22.
I have version MIUI 8 global. I have also heard that I need to flash the Chinese/english version to unlock.
If anyone has an idea for the correct way to go from here a competent feedbck would be greatly appreciated
You have to request permission from Xiaomi to unlock your bootloader.
Hi all,
I've purchased a used P20 Pro from a friend which has an unlocked bootloader and has been previously rooted. I normally keep my phones stock so I want to lock relock the bootloader (I have the code) but despite trying to follow various guides I have been unsuccessful.
Would anyone be able to guide me through the process of relocking the bootloader please?
The main reason I like to keep stock is manufacture updates etc and I don't have the knowledge to maintain a rooted phone.

I don't believe that an unlocked bootloader will prevent you from getting updates. As far as I know the only difference is the warning you get when you boot that "you can't trust the phone."
IF YOU BRICK YOUR PHONE IT'S YOUR RESPONSIBILITY
Don't know if there is another way but of you have fastboot and adb you can do it:
1. Make sure developer options are enabled
2. Connect your phone to the computer using USB cable.
3. Open a command window and type 'adb boot bootloader'
4. Once the device has booted into the bootloader mode type 'fastboot oem lock'
This WILL ERASE all your user data and you will have to configure everything from scratch. You will need the unlock code if you ever want to unlock it again so make sure you don't loose it.

Ok so I just upgraded to android 11 and want to unlock the bootloader but while doing it through the app it says failed to unlock the device why is that?
Also I have never unlocked my device before it's the first time I'm trying to do so..
Do a backup of your data you don't wanna loose and flash raw file with A10 available here in ROG3 section. Then your unlock tool will work. After you unlock you can update and restore data. Bootloader remains open until you lock it again with abd or app.
My rog 3 tencent version is not unlocking bootloader, bootloader is failed to unlock your device plz help me
How did you attempt to do it? Steps please.
Same issue here. Previously I was just downloading the Unlock Device app here and running it. (I already had developer options enabled) and the device would reboot but not do anything (I reckon I tried 10+ times). Since then I formatted the device and tried again and got the same results so I set the device backup normally today (running build 18.0410.2108.158) and tried it again (with and without developer options enabled as I forgot to check) and I just get a standard error message saying it couldn't unlock my device and to try again later. Same result multiple times. I don't see any option for OEM unlocking in Dev options which I see some people mention. I'm updating to the latest OS I can see in the link I provided and I will try again after installing that.

Hello
Your phone has already been unlocked earlier and has the flag removed. Someone blocked it again for sale.
So you won't do anything with Asus tools.
I recommend the EDL mode
