Unlocked my bootloader for nothing

Peace be upon everybody, and good morning/evening
Last night I remained using my PC for a whopping 9 hours of work to figure out how to unlock my E6633 bootloader - and I finally figured it out.
The whole process was bumpy and the Sony Mobile Developers tutorial didn't wholly work out, but it had some vital info for the process. I had to unlock the boot loader using the Flashtool (thankfully), and I had some lack of luck at the beginning, which involved a journey to find the lost driver for my Z5, and to install it in the Device Manager (took some time). And then I took a "detour", since facing another roadblock, by creating a folder in C:\Users\<User>\.flashTool\registeredDevices named by my devices code (that appears when you enter adb devices in cmd), then inside of that folder I've created a .txt named ulcode.txt which contains the serial code provided by Sony Mobile to unlock your boot loader. And I've gotta tell you, it was all a pain in the bass.
More frustratingly, this whole procedure has resulted in zero luck with rooting the goddamn device (thanks Sony), and now I'm stuck with an unrooted bootloader-unlocked device . I'm sure this requires taking another detour. I've failed in every way I know to flash the modified stock kernel for some reason. I've tried cmd to flash the kernel and it comes back with FAILED <Remote: command not allowed>. I've also tried Flashtool to root it directly, and it turned out to be non-working as well.
Now, I'm not going to complain about this whole situation, even though I'm recalling how easy rooting my good old Galaxy S3 was. I'm now looking for a solution for that last tiny bit of the puzzle, and I'm sure there are other fellow members who are facing the same hitch.
Cheers .

Is oem unlocking ticked? It sounds like your bootloader is still locked.
All I did to unlock mine was type the command Sony provided with the unlock code and unlocked it with fastboot, took maybe 10 seconds?

After unlocking the bootloader does the phone reset to factory settings? Just to make sure that you succeed unlocking.

Go to developer options and check if oem unlock is ticked

This difference in rooting experience that the OP had with the GS3 and now with the Z5 raises a question in my mind. Is the modding community more focused on popular devices? This is often a deal breaker for some people. If the 6P or the GS6 gets more ROMs and mods and faster root exploits than the Z5, then I myself would prefer those devices over the Z5.

It is indeed ticked and I'm positive that the bootloader is unlocked.
Yes I tried the easy way of doing it with cmd but it just didn't work out. Kept returning with FAILED <Remote: command did not succeed> and that's why I resorted to the other way of creating those files in the flashtool folders (as explained in the OP).

I think maybe the developers at Sony are narrowing down the possibility of modifying their devices.

I went through the steps in that thread and without any problems until the part with
Code:
fastboot –i 0x0fce oem unlock 0xXXXXXXXXXXXXXXXX
I have checked the recognition of my device by entering fastboot devices and it recognized my device successfully.
The X's above being the code provided by Sony, the cmd window (of minimal adb and fastboot) returned with
Code:
FAILED (remote: Command did not succeed)
Although, the step prior to this one which is to unlock the bootloader using Flashtool has succeeded.
It's really mind-boggling...

As far as i know that unlocking bootloader will reset ur phone to factory settings.
And not sure but i think you need to remove a number from the code sony sent to you.

Take a look here: http://forum.xda-developers.com/xperia-z5/general/guide-sony-xperia-z5-unlock-root-tweaks-t3298224
Bootloader unlock is under # STEP 1 - GENERAL GUIDE
I hope this will help

Also check if you're bootloader is allowed to be unlocked.

Type in dialer *#*#7378423#*#* (*#*#SERVICE#*#*)
Service info > configuration > rooting status.
If it says bootloader unlock allowed :YES you can unlock it, if it says NO u can't unlock it.
If it says rooted or unlocked, you've successfully unlocked it already.

UM, I have E6633 and everything works fine... I used flashtool to unlock bootloader.

Carrier lock, unfortunately as far as I know since the very first Z series impossible to unlock unless u contact the carrier and they unlock it for u.
Keep in mind that they might charge u for that.

Sorry, as the model is not the same, I would not risk buying a phone which doesn't support the ROM you deserve. Can you get it somewhere else as an a9?
I believe that you can buy it from htc's website. If your looking for installments/monthly payments. They offer PayPal's installment program

Technically speaking, the phone is considered the HTC One A9s, model 2PQ9100, FCCID NM82PQ9100. The hardware is identical to any other A9 UHL variant.
IF the phone can be can be rooted, I'm pretty certain that you'll be able to s-off with Sunshine and do a full conversion. Maybe @jcase knows more.

Even if you couldn't flash cm13, it would definitely be able to run Supersu, as it is obviously some variation of hiae, you could flash TWRP.

Here's the catch...
Unlock bootloader>flash TWRP>install SuperSU>use Sunshine to s-off ---the device could then (in theory) be converted to the desired A9 MID/CID, and be like any other non-Sprint A9
OR
(Somehow) get root with locked bootloader>Sunshine bootloader unlock and s-off ---same result
If the bootloader can't be unlocked, and there's no way to root otherwise, then the device will be locked down tight until a root exploit is achieved.

That's true, unless the carrier has prohibited unlocking and/or htcdev doesn't support this carrier branded variant, which is possible. There's just no way to know without additional information.
I wonder if there's a RUU for this device...

Awesome! That means that a full conversion to unlocked should be possible. Are you going to have the first known converted Signature Premium?

Haha thanks I think. The difference here when I flash recovery and unlock I needed to go to bootloader mode not in download mode. (similar to another device)
My phone full root now. And well function. About conversion? Maybe if this model no longer receiving updated (I mean unlocked device)

It's pretty strange that fastboot is implemented differently than with the A9. It would be logical for the Telstra to share a similar firmware base.
Do you mind posting the output of fastboot getvar all and cat /proc/emmc? (remove your IMEI of course)

I never heard of it. FWIW, with a device that has an unlockable bootloader, one would use FASTBOOT, not ADB. Command is:
Fastboot OEM lock
With that said, I haven't a clue if this will work on your device.

The g9500 (the snapdragon s8 family in Hong Kong/china) is unlockable using the crom service/KIWIBIRD in steady thing.
Unfortunately I have no idea what is involved. Why do you want to relock? Did you flash something already? FYI if you are 0x1 WARRANTY_VOID you cant undo that part

My problem is, that Samsung Health is detecting " rooted device"

Anyone managed to root lg k51?

I can't find anything definitive about whether it's rootable or not

Same here i tried every root app possible and failed.

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 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.

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.

Question How to unlock bootloader?

I just received my Flip3 (SM-F711U1) and would like to unlock my bootloader. However developer options is missing the OEM Unlock option. It's completely missing not just grayed out. I read a few articles about needed to change the system date but none of those guides changed anything. Can someone help?
Also, I attempted to call *#*#7378423*#*# to double checked that it wasn't already unlocked and I got a popup saying "Unabled to process the request."
Thank you.

- Hit settings
- about phone
- software information
- build number 5 times
- profit

You can try directly unlock without ticking the oem unlock. By boot into download mode. The other thing is your device or carrier or country wont allow your flip 3 to be unlock. There last step you can try is clean flash via odin with your latest firmware.

They used to, so there was always a possibility it returned.

I recently read this article on XDA about unlocking the boot loader on the Fold 3 which results in Samsung disabling the camera (WTH?), Is this a thing on the Flip3 too?

My device is rooted. I have always been able to find the OEM unlock option under developer options without any constraints.
My camera is NOT affected. I can still use it without any issues.
I have an European device (SM-F711B).
Hope this helps some of you to track down whether this is a location or carrier based problem.

Hey Redhatter,
Out of topic question, but are you getting Tmobile 5G just fine?

I just received my Flip3 (SM-F711U1) and would like to unlock my bootloader. However developer options is missing the OEM Unlock option. It's completely missing not just grayed out. I read a few articles about needed to change the system date but none of those guides changed anything. Can someone help?
Also, I attempted to call *#*#7378423*#*# to double checked that it wasn't already unlocked and I got a popup saying "Unabled to process the request."
Thank you.
