How to unlock bootloader on your 'Sony Xperia E C1504/C1505' // Bootloop fix!

Hello!
Today I am gonna teach you how to unlock (and relock) your bootloader. Also fixing bootloop.
Disclaimer! Proceed at your own risk! I am not responsible if anything happens to your phone. Although if you follow every step carefully, you won't have any problems. Unlocking bootloader WILL void your warranty, but you can relock it, so it's under warranty again. Also back up your data!
So lets first talk a little bit, what bootloader is and what a bootloop is. Bootloader is required for some mods like CWM, custom ROMs and so on. Bootloop is if you have unlocked your bootloader, and try to boot your phone, but the booting animation will start to replay, so you basically can't boot up your phone.
Make sure USB Debugging and Unknown Sources are enabled.
But lets get to unlocking the bootloader, shall we.
First, on your phone open Dialer. Type *#*#7378423#*#* to acces the Service Menu. Select Service info, then Configuration, and look for Rooting Status. If Bootloader Status says Yes, then you can unlock your bootloader, if not, stop right now!
Now take a piece of paper, and write down your IMEI - you are gonna need it later to get the bootloader unlock key.
Nextly, download and install Flashtool.
Once installed, go to this site. Fill in the information, and you should recieve a bootloader unlock key onto your eMail.
Now open Flashtool. Click the BLU icon. Then unplug your device, turn it off, hold down the volume up key and then connect your phone to your PC via USB cable. (This is Fastboot Mode)
Once you have done that, you should be promoted with a screen asking for your bootloader unlock key. Type it in and click Unlock and your bootloader should be unlocked now.
To relock, repeat the process of unlocking (click on BLU, connect in fastboot mode, and so on) but this time you will get an option to Relock. Click on it and your bootloader will be locked.
Now, continue reading if facing bootloop, like I did. It's common on our devices to face bootloop, but you can probably come out of it.
After unlocking, try to boot up your device. If not able to boot up, take out your battery. Connect your phone to the PC in Fastboot Mode.
Now relock bootloder. Boot back to Fastboot Mode and unlock it again.
Now flash Xperia E's Stock Full Firmware via Flashmode. Wait for it to flash. First boot might take a while, but hopefully you don't face bootloop / come out of it.
If this guide helped you, then please click thanks!
Any questions? Just ask them and I'll answer!

No. Because your DRM key cannot be recovered since you unlocked your bootloader.

[Q] Can Bootloader be unlocked

my Xperia L C2104 device does not show any YES or NO in the bootloader unlock allowed section of service configuration.
It only shows like this:
Bootloader Unlock Allowed
and no yes or no after that.
Also I tried to unlock the bootloader previously via official method but it showed Error: Bootloader cant be unlocked officially.
Help me guys, Can the Bootloader be unlocked in my device and if yes HOW? Any Unofficial method there for unlocking bootloader plz convey that...also m a NOOB so simpler language appreciated :silly:

The phone doesn't need to only show YES or NOT.

I also tried that method a month ago. I will try it again. but the commands given in the website arent accepted. they show error with tht commands. :crying:

I had tons of problems with this, I thought all was lost. I have win 8.1 x64 and assumed it was a driver problem and so did the unsigned driver install in windows safe mode. No dice, flashtool continued to be unable to unlock. What worked for me was re-submitting my code to sony, I got a totally different unlock code and then it worked through flashtool! Maybe give that a try? Fingers crossed!!

Oneplus 7 pro bricked bootloader lock

Hi guys I have a OP 7 pro bricked (boot loop), I try everything to un bricked, that is why I ask for any help. I use msm tool and install several zips but when the tool finish it still have the same problem, I can access to the fastboot mode but my bootloader is locked, so I cannot try the fastboot method cause my pc won't recognize when I connect my phone in this mode (I think that's because I need to have enable usb debugging).

I've got bad news, if your bootloader is locked and MSM tool fails you will most likely have to send it in as it will no longer be easily fixable, I unfortunately had this same issue on my OnePlus 8 and learnt the hard way.

You said that you "cannot try the fastboot method" because your PC won't recognize your phone... did you install Oneplus fastboot drivers correctly? You should be able to access your phone in fastboot, even with bootloader locked.
Try with another PC too. Just my 2 cents, sorry if this doesn't help you...

First thank you for your time.
I though that too, but i didn't do it , maybe is because I read that in order to use this method (fastboot), oem unlock and usb debugging have to be enable on my OP 7 PRO
Ps: today I'll try again whit another pc, maybe it works, I think the Qualcomm drivers, adb drivers and OP drivers are a nightmare, who knows how many I've been downloaded those in order to make everything right
Sorry for my English I'm from Costa Rica

Sounds like he is stuck o. The older firmware that don't recognize oem unlock command. Not doing the developer preview upgrade then Ota out to regular firmware. Kinda sounds like what I started out on this t mobile one

Hi MadScientist do you hav the same prob? Didi you solved?. Like I said I think the fastboot method to unbrick doesn't work for me because we need to have oem unlock and usb debugging enable on the OP. I will use another pc to discard
Ps: don't know what you mean with "older firmware"
Since I don't remember what version of firmware I have I try the older 9.5.3 to 10... On oxigen. Even i read that someone resolve his problem installing the Chinese version (hidrogenOs) I don't remember the exact name

simple , go to about phone and try to find build number,
after you find build number tap on it until it says you are in developer mode
after that head on to developer option (it may be inside about phone section or above about phone section) turn on the option which says allow oem unlock. then,
just reboot to recovery mode either by pressing volume up or volume down key with power button.
after you enter recovery connect usb cable and open command prompt in pc and make sure that lg device drivers are installed on your pc also make sure you have adb and fastboot installed.
ok, after all this type command
adb devices
if any thing shows us then you have successfully connected your device.
after it type
adb reboot bootloader
then your mobile should restart and show fastboot mode in screen
type command
fastboot oem unlock
and done your bootloader is unlocked.

I meant TWRP recovery . After you've unlocked the bootloader where did you get a custom recovery to flash for the LG k51. From what I saw on Team Wins website, there isn't one.

I doubt that's going to work, but let me know if it does. Carriers and manufacturers use a variety of sophisticated security schemes like requiring lengthy codes that only they can provide, etc to purposely make it very difficult to unlock bootloaders. Tmobile gave me a K51 for free. They apparently feel the have to pay for it by spying on me. I bought a moto g7 plus unlocked for $117 directly from Moto and put Lineage on it, no gapps Would love to use thie k51 though if anyone figures it out because it's more waterproof and bigger battery.

Whether device's bootloader is unlockable / device's Android is root-able or not you easily can find out by means of ABB:
Code:
adb shell "getprop ro.oem_unlock_supported"
If returned value is 1, then it's supported otherwise it's not.

and let me guess my doofus luck im guessing no way to unlock it with out a P.C. like nuttin at all?

Absolutely no of the crap above works at all in any capacity especially sprint. Generic postings like hold volume down and power also doesn't work to go into fastboot so if you guys are following the advice of some of these guys don't because you'll drop more money on a new phone then you will unlocking it some variants verizon is one I think you have to call LG I know I spent 6 hrs on the phone with "tech support" aka "jokes with a screen to read from" to FINALLY get into touch with an engineer who told me the only way "NOW" to unlocked the bootloader is in his office which means it has to be depot to be unlocked which as of this moment lg is not doing that WILL change in the future that was 12/03/2020. Even running external adb with kali linux to hack it broke the bootloader and sends you into an infinite reboot loop

This returns no value on a locked bootloader because even with Dev. Opt. Enables its still read only until bootloader is unlocked this is verified on two carriers k51's sprint and att. However it is unlockable we haven't found it and/or LG has not added this service to their site which is where you will get the info needed for the unlocked.

Oh my. You know you need to do all this from a computer, right? Can't do it in an Android terminal because fastboot commands are only valid in a phone's bootloader environment. And if you didnt know that then rooting and all of the dangers that come with it just isnt for you. But yes, it's rootable. So here you go anyway.
Reboot the phone to download mode.
Install LG's K51 usb drivers, and install adb and fastboot, on your computer.
Open a command prompt and type: fastboot oem unlock
If it does anything other than pat you on the back and tell you it's proud of you and how well you follow instructions, then go back and follow the effing instructions.
Otherwise, type: fastboot reboot.
Download magisk manager.
Do the magisk manager.
Use the LG flash tool on your computer to flash what you just did when you did the magisk manager.
And presto, you're rooted. Or I successfully left out enough info and you dont know how to use Google, leaving your device still not rooted. And thank god for that.

Ive been learning from xda for some time now. Bricked a few phones in my learning curve and tonight i had my first success with my g7, and wrighting this on my new k51. This is my first post and I think that was pretty rude of you to say. This is supposed to be a place to learn, share knowledge, and help those who are less educated. Not look down on people and say crap like that. If he wants to learn even if it takes a couple bricked phones to do it, let him. Either give him the proper procedures or dont say nothing at all. How long did it take you? How many phones? Its taking me quit a while but i am finaly getting somewhere. Keep with it guy. Dont let this dude, or any one else for that matter, bring you down.

Yo Ken,
So your K51 rooted?
If so, maybe you could provide a step by step?

I haven't done this yet but is it verified working? I did a google search came across the method to do the unlocking but it showed it was a failed project?

How To Guide [ROOT][GAPPS] Root and install GApps on stock Edge S/Chinese version

So you got the Edge S and want GApps? Basically you unlock your bootloader, root with Magisk, then install MagiskGApps.
DISCLAIMER: UNLOCKING YOUR BOOTLOADER MAY VOID YOUR WARRANTY, AND DOING ALL THESE THINGS IN THIS GUIDE MAY RESULT IN DAMAGE/BRICKING YOUR PHONE. I AM NOT RESPONSIBLE FOR ANYTHING YOU DO TO YOUR PHONE. PROCEED AT YOUR OWN RISK.
1. Unlock the bootloader: that should be doable with their global bootloader unlock website here.
2. Download Lenovo Motoroa Smart Assistant (Rescue and Smart Assistant), and follow its instructions to "rescue" your device. It will lead you to boot into bootloader mode and download the firmware. Find the firmware file via the LMSA's downloads (should have a "show folder" button). You'll need the boot.img file for Magisk.
3. Download Magisk, then follow its instructions. You'll have to copy the boot.img to your device, then use Magisk to patch the boot file, then copy the modified one to your PC.
4. You'll need fastboot. If you don't have it already, you can download the Android SDK platform tools here. Then go into the folder, Shift+Right Click the folder, then "Open Command Prompt" or "Open PowerShell," you should have something close to one of those two. Copy your Magisk modified .img file to that folder, then you'll want to input:
fastboot flash boot [modified .img file]
Once that completes, you should see in large text, "Start" on your phone next to the power button. Press the power button, and it should boot, and you should have root now.
5. Download MagiskGApps to your phone, open Magisk on your phone, click the button that looks like a puzzle piece at the bottom of the screen, "Modules." Click "Install from storage," locate the MagiskGApps file, and install it. After that it will ask you to restart your phone, do that, then you'll just have to be patient as it takes time once its restarted to load everything. You also may need to update some or all of the apps, then you should be able to use the notification to finish setting up the phone with Google Setup.
Thanks to Motorola for making it easy to unlock their bootloaders
Thanks to the whole Magisk team for making an easy, awesome root (and more!)
Thanks to Wacko1805 (and team?) for making MagiskGApps. This is really awesome.

Magisk has a "Magisk Hide" which will allow it to pass SafetyNet, and most things which check on device security will think the device is secure. But unlocking BL and rooting does make the device less secure, and therefore incurs its own risks apart from bricking or damaging the device.

Google Pay works. But according to the Motorola website you should be able to relock the bootloader if yours doesn't work. But there's never any guarantee. If you need your device secure, recommend don't unlock bl or root, or wait to see if there's a root option without bootloader unlock that can be easily undone.

I saw that someone’s edge s had unlocked the BL and Flash G100 firmware and everything worked normally, and then tried to lock the BL again, but it was unsuccessful and the system could not start. The flashing tool does not recognize the machine.

That's not good. Hopefully they can restore it back somehow. With this guide to unlock and flash gapps why would you need to flash G100 though? This seems to be itright now without one of rom developer's releases to get root & apps. For me this is all i would look for. Titanium backup on it and restore.. done until PE rom comes out.

I would think yes, if you flash different firmware, locking the BL would likely cause problems. It's very difficult to do anything w/o unlocked bootloader, except sometimes rooting is doable. That's pretty much the behavior I expect. If they come to this subforum, we might be able to help.

thank you. They did not ask for help. It seems that the lock BL is a self-verification switch, and then performs a verification system integrity.

I'm curious,If you unlock and flash other firmware and then flash back to the original firmware, can it be locked again?

Mine doesn't let me unlock its BL. I've got unlock code from moto and did a factory reset with SIM card in slot 1. After enabling developer mode and debugging the switch still is greyed out. So no chance to unlock it.
Has anyone got an idea what to try now?
Moto support answered yesterday to my request but also no solution since I told them that it doesn't work
Device is not branded. I got it from Amazon so no provider branding.
If this won't be able to be unlocked and rooted I'll have to return it and switch to a Google Pixel.

I had the same issue, you need to factory reset WITH your sim card in the phone, this will let you open the OEM unlock slide thing in the dev mode.
Then once its done you can fastboot and unlock the bootloader.

I did so, maybe I explained not so well. SIM was inserted and then I did factory reset by starting it from settings. After restart it's still the same - switch / unlock slider greyed out.

On my OG Pixel XL, I had to wait 7 days for the slider to become normal. By the time I got around to do it on the Edge S it was about the same time.... could be related

Now as you said that I remember that thingy with another device. Maybe a Xiaomi I think... With that I had to wait several days until the unlock code was delivered.
But there was a message, too, when trying to get it sooner, which said you needed to wait some more time.
Not sure if it's the the same for Moto devices? Then again, when thinking that you experienced the same with a Pixel, too...
Did anyone else make such an experience with his/her g100?

Make sure your on the latest OTA, Lenovo made a mistake on previous versions with the OEM Unlocking function not being enabled. They fixed it in latest ota.

RSA tool said the file I uploaded yesterday is the latest one available (and it's exactly the same as the installed version).
The device was released just a few days ago in Europe. Perhaps they fixed the unlock switch in other regions and still need to fix it in Europe..
Will wait until weekend if they come up with a solution. If not I'm afraid I have to return the device as I need it personally AND professionally, too - I'm field agent, so.... :/
