[Q] Bootlader unlock problem. Help??

Hi I've tried searching about quite a bit but can't seem to find the correct solution.
I've had the bootloader unlocked once by following DoomLords instrucions but locked it as an upgrade popped up on my pc companion, now I can't seem to unlock it again.
I've followed the same process as before, even through the sony bootloader unlock site (this gave me the same unlock key as before) I've attached my error from the command prompt screen.
Anyone??
the screenshot is not readable.
maybe you forgot to remove the last number form the unlock key.
or flash a firmware first then try again
Sorry here's another screen.
I tried to re unlock the bootloader after an update via pc companion, it didn't work then.
I've now flashed ICS onto the phone with flash tool and unlocking the bootloader still doesn't work.
I've tried taking the last digit off the unlock code, with no luck!
Random post to keep the thread alive, hopefully someone will know whats up
Last try, anyone?
You're not using 0xFFFFFFF as the key are you?
No definitely not. That was the error the 2nd time round trying.....

HELP please... HardBrick RN3SD

i don't know what to do... i think i read every tutorial for unbrick my phone but nothing works...
my situation:
-i unlocked my fone by unnoficial method, instaled twrp and everything was ok.
i decided to instal sMIUI, but nowhere i read that is necesary to delete emmc file... so i bricked my phone.
bootloader got relocked, i can't turn on my phone, mi logo appears during 1 sec > screen off > again mi logo during 0.001s > screen off
when i plug in my phone into my pc, i have black screen and red led, but it's not adb mode.
i can't enter adb, my pc (windows 10 x64), i use command "adb devices" and list is empty
i can't edl
i can enter in fastboot mode.
i can't flash nothing, "failed: device is locked"
anyone can help me?
if i unlock officialy my bootloader, can i flash again stable rom or something? i just had my phone during 2 weeks.
can i do anything?
thanks.
one more thing: i had guaranty, so, if i unlock my bootloader officialy, i lose it?
i don't want to try testpoint method, because of guaranty.
Well, welcome to the party.
Irrespective of how much u search, cry for help or open millions of threads like this instead of doing a little search, there is no solution except test point method. Now don't ask how to do it. Search and read a little u will get the necessary info.

thanks a lot for this kind help, i will do it, don't worry. :good:
Don't worry bro u will certainly do what is required. I was the first who reported a bricked device while unlocking bootloader by unofficial method. After extensive search and trying different methods I came to this conclusion.

Vodafone VFD 300: Unlocking bootloader not allowed - says it's "secure".

This is a problem, and it's doing my nut. I have a Vodafone Smart Mini 7, which I desperately want to root, to get all of Google's bloatware and the stuff the original network provider put on it.
I've already unlocked it to all networks, but the bootloader is being a PITA. I've done the usual with adb and fastboot, namely put it into USB Debugging, and then done this;
Code:
adb devices
adb reboot bootloader
fastboot getvar all
When I get to the section on the bootloader, it advises me that it's Secure.
I tried to use
Code:
fastboot oem unlock
and when I confirm on the phone that I want to unlock it, I get told that Remote Unlock is not allowed.
I assume that the fact that fastboot getvar all says that the bootloader is secure, means I need some sort of key to get it off. My old network provider don't know where to get it from, my tech team don't know where to get it from and I'm screwed.
Anyone got any ideas on whether I can get round the "secure" part of this, like some way of finding the key for it? Thanks

I have the exact same issue I read some threads and nothing solid has come out of it some say they managed to get root but others say they bricked the phone
Any news on this topic? I too have one i desperately would like to root because it is permanently full and you cant do anything wih it. The Google apps and the apps installed by my service provider take up all the onboard storage space. I downloaded only Whatsapp and Facebook Lite and bam,the phone is completely full and useless as it cant do updates,runs extremely slow and does all sorts of random stuff like restarting on its own etc. driving me utterly insane.

Cant unlock bootloader with DC or HCU

SOlved:
so I was unaware that the bootloader unlock was going to be a problem before I purchased this phone... I did some research before making the purchase and it seemed all was good.
I spent $17 with DC for an unlock... all I got was some nonsense "temporary unlock" SO once I run the temp unlock the phone says "unlocked" on both the phone and the FRP.
FYI.. I also tried HCU client... and it can find the phone but then when I hit "unlock" it says something about a COM error and cant get the code... I tried this with 2 different PCs as well.
I was able to then push the TWRP recovery to it via fastboot. I then did fastboot reboot and went straight into the recovery... and no luck. it brings me right into the EMUI recovery.
is there anyway that I can at least get into TWRP temporarily since I do have the temporary bootloader unlock? or any other way that I can push supersu via fastboot?
this is very frustrating...
Ok so I CAREFULLY re read the directions for HCU... HCU is to be run while the phone is still on in the OS. not in fastboot which was my mistake all along.
so the key is to go into the dialer and enable manufacure mode... then run HCU while the phone is still on.
another key is to disable the Huawei software ... IM not sure if this is necessary but I think its a good idea because I noticed that the software itself causes the phone to go back to Hisuite mode instead of manufacturer mode. so I went into windows services and disabled hisuite... and closed out of it.
Hope this helps someone else
and do not waste your money on the DC program!!! you have to purchase your credits from DC but dont use the DC client. I am currently working on getting a refund for my first wasted credits. also they charge 15 credits for this unlock which is $18 USD! but thats not so bad considering I got this phone for $499 from newegg brand new

Temp unlock lets you flash anything (stock images) from fastboot. So essentially you could flash a whole firmware using only images in Fastboot mode.
Twrp don't work as you need to be unlocked to use it, even if you have Twrp it will reboot to sec_recovery when you are locked.
Do you remember wich firmware was in your phone before you unlock your bootloader?

In a weird position. How do I root my phone?

So I got this Sony Xperia X model F5121 from one of my relatives, and I ran into quite a few issues when I tried rooting it. it says Bootloader Unlock Allowed: NO, which would mean that i couldn't get into fastboot mode and unlock my bootloader but here's the very specific and weird part: I can get into fastboot mode, at least I believe so. My phone was carrier locked to Vodafone but I payed a professional to unlock that and now I can use every SIM I want. I looked online and the first XDA page said that unlocking the SIM meant that fastboot mode is unlocked as well. So I tried, I plugged my phone in while holding the volume key, a blue light popped up and it meant I was currently using fastboot mode, but when i try doing anything it says "waiting for devices" and doesnt end up working at all. Am I missing some drivers? Is it just impossible? Could one of you be kind enough to provide the needed files and some instructions for this procedure? i'm asking for a lot, I know but if there's anyone kind enough. I'm running the absolute latest version of Android 8 Sony provides.
EDIT: YEs, used adb shell, I have the ADB drivers, I tried the szuzu install or what the TWRP codename for it is, but everything just stops at "waiting for devices" and I can't do anything.
Since you are not allowed to unlock the bootloader - Bootloader unlock allowed - No, there is no way to unlock it and root it. Sorry.
even if you want to try again, make sure to force install googles drivers
instead of sonys
