I recently tried rooting my Sony Xperia M. The rooting process was successful but I soft bricked my phone when trying to unlock the bootloader following the instructions on SONY's site: (developer.sonymobile.com/unlockbootloader)( I am posting the link this way as external links are not allowed currently) The instructions were confusing and unclear. I still haven't been able to understand the instructions, especially the part where it says to plug the device in flashboot mode after which it will ask where to install the driver(Such a driver installation request never came up for me). So I installed flash tool from a link I found in this site and installed the drivers (I had also downloaded the sdk package given in the instructions in SONY'S site). But after I ran the commands in cmd, the phone never rebooted(it was stuck in a boot-loop). So I took it to the service centre and now it's in the unrooted form. I really wish to install the custom fw but I dont wanna brick it again. Clear instructions for unlocking the bootloader would be highly helpful. (btw I am using windows 8 on my PC)

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.....
Hello,
I've tried to unlock my bootloader on SGP321. I followed the instructions on the sony website, but when I try to download the fastboot driver to replace in the android sdk, the downloaded file contains only a setup info file named android_winusb. No .inf file, so when I connect the tablet to the pc holding the fastboot button (volume+) I get a fastboot s1 device and Win7 cannot find any driver in the sdk/extras/google/usb drivers folder (as per sony's website instructions).
Does anyone know what's going on and provide some advice on how to perform the unlocking (my bootloader is unlockable, as I checked following sony's instructions).
Thanks for any help guys!
Luca
Hello, I am not sure if I got your problem right, but if you are searching for Fastboot drivers for the XTZ, then see this post. I just did this yesterday and went through the process too. For your convenience, I have packed just the installer file to a ZIP archive and uploaded it here: http://mysharegadget.com/333422488
And if you haven't done so already, do not forget to backup you TA partition before the unlock, see this topic. It will allow you to return back to the normal locked state with DRM keys.
I thought I replied to your message, but I guess I just hit the thanks button!
However thanks again for the useful information.
Hi Fellow Users!
I just bought LG v10 yesterday with international warranty even though i live in UAE, the problem is i am following all the steps from "step by step guide to root for tmo" but unfortunately i am not able to boot into phone recovery which is odd for me as i am a long time user of android, is that possible my phone doesn't have one? I tried everything adb, manually but nothing worked, i once booted my phone into recovery via adb but i saw green android picture with no command written on it and fastboot didn't worked there so there is that.
1) i tried dirty_cow but stuck at getenforce "permissive didn't appeared which is must needed, i think its related to my bootloader"
2) should i follow LGUP procedure even i am not sure my bootloader is unlocked?
P.S my phone is TMO although its unlocked to use any network.
Please advise, thank you
Unfortunately flashing KDZ file bricked my phone, :crying:
Now its just off it doesn't turn on tried everything any advise?
Update: Went to LG TechServe and handed over my phone to re-flash the original firmware, bad thing they don't cover international warranties as i live in UAE and the model i have is TMO with international warranty so there's that.
Reason to share the story, may people learn from this.
Have you tried with Kingroot app or kingoroot app? These apps can root many devices.
I read other threads with the same issue, before post this , but i cant solve it yet
Rooted HDX 4.5.5.3 -Check
Set developer mode on the Kindle -Check
Allow USB Depuration before proceed -Check
Downloaded ADB Composite Drivers / Unlock Bat's / ADB Interface- Check
I run as admin both files without problems, abut the error appears when kindle reboots "Unlock Failed- Unlock code is not correct"
(The files are placed on the correct site,by the way)
I tried
Download again ADB + Fastboot
Reinstall ADB Composite Drivers
Reboot Kindle
Download again Unlock files from original thread
Erase mutiple times unlock.code
No sucess at this point
Any suggestion its apreciated, serial number seems ok
I dont try downgrade yet , because someone post recently he bricks his device using this procedure, so i prefer stay away if is possible.

You need to install a vulnerable bootloader before unlocking. See step #2 in OP of linked thread. Scroll to the end of that thread to secure the referenced files as links in the OP are dead. Proceed with caution; a simple mistake can yield a world of hurt and potentially an unrecoverable device.
If your device is rooted you do NOT need to downgrade.
Yeah im following the steps correctly, i try again on my desktop tonight with Windows Vista , i think its some issue with W10 FCU on the laptop, when i tried unlock bootloader on my Blu Life One X2 on w10 , the system show excatly the same issues with unlocking tools, i repply the results

Can you boot into TWRP after completing step #2 of the unlock procedure? If not it is likely the vulnerable bootloader (ABOOT) was not properly installed.
Step #2 can be performed independent of steps #1 and #3. IMO it should be the first step taken after rooting. There is no need to generate an unlock code (step #1) prior to installing and testing the vulnerable bootloader and TWRP (step #2).

I can't boot into TWRP after installing aboot_vuln.mbn. What should I do now? My tablet can only get into fastboot.
Couple days ago I tried to install TWRP on my Z4 Tablet, which was ALLOWED YES and I unlocked the bootloader by using the guide on Sony Website. but I failed to install TWRP I always had this Error: waiting for any device. So I tought the problem would be my PC Windows 10 so today I decided to install the TWRP on my Tablet by on Linux Debian (Kali) and I had this error again so I checked *#*#7378423#*#* and I saw this: Bootloader Unlock Allowed : NO it just turned from Yes to No. And yes I am sure it was 100% at the begining YES. And the USB DUBBING was on all the time. I need your help. I really need the TWRP.
