How to know is my bootloader unlocked? Ty

how to know it isn´t ?
-You don´t have d851
Other variants than tmobile are using bypassing(means --bumped boot source, kernel, recovery) in order to fool the bootloader that it´s a legit signed boot option.

Bounty for unlockable bootloader!

I'd gladly pay 50 dollars to anyone who could deliver a way to unlock/replace the bootloader on D5306. Or at least some kind of Loki to be able to load CM11 and recovery.

In your device, open the dialler and enter *#*#7378423#*#* to access the service menu.
Tap Service info > Configuration > Rooting Status. If Bootloader unlock allowed says Yes, then you can continue with the next step. If it says No, or if the status is missing, your device cannot be unlocked.
My bootloader says it's unlockable. There has to be some sort of LOKI, or JTAG device that will replace my locked bootloader with an unlocked one.
If your boot loader is unlockable, all you have to do is follow instructions on that site to unlock it. There's no need for JTAG or LOKI

Thanks for the tip, but my bootloader is unlockable by that method.
I'm sorry if i sound rude but do you know what unlockable means? If it's unlockable, that method should work because it's OFFICIALLY SUPPORTED BY SONY ITSELF. If it's not, then too bad. You have to find some other way

I've seen previously unlockable bootloaders replaced only by Jtag. Or a workaround like a Loki created. My wife's S4 uses a Loki to be able to boot cm11.
I really don't think either of those things are impossible.
Someone who might have a 5303 or unlock D5306 lying around could extract the bootloader and put it on a Jtag adapter and package it with instructions on how to disassemble the phone, and reprogram the bootloader. If that can be done, then the bootloader should be open from that point onwards. I would gladly pay for one of those packages. Might be a nice kickstarter project to raise funds to ship the adapters. Or maybe a Groupon purchase. But impossible, I think not. I've soldered too many Jtag adapters onto Xbox's to replace the bootloader. I know it can be done.

[Q] recovery locked bootloader

As the title says, I was wondering if it was possible to have recovery without unlocking the bootloader. I know that sony phones have recovery.img unified with boot.img and that is not possible to flash custom kernels with a LB. But on old xperia U there was a way to have recovery without needing to unlock the bootloader.
Thanks in advance

S off is just for if you dont want to wipe apps correct?

S-off is for converting your phone to a developer edition or International (by changing the CID / MID and flashing a RUU)
or flashing unsigned firmware and for flashing RUU that are older than your current version.
to get s-off you must already be unlocked and rooted
O.k. so basically I need a computer there's no app,etc that can unlock my m9 correct?I don't have a computer that's why I'm asking. Thanks In advance!!!

S-off is required to update or flash certain parts of the system... but not for custom recovery (TWRP) or custom ROMs. That only requires an unlocked bootloader from HTCDEV.com
For example, once you have a custom ROM, you no longer receive OTA updates. OTA updates not only include the ROM, but also firmware updates as well. Custom ROMs do NOT include firmware updates. (I.E. the latest camera fixes, and updated radios for better signal and improved battery) Developers will often rip the firmware out of the OTAs or RUUs and provide them to be flashed separate and without wiping your device. These are modified (I.E unsigned). Modified, unsigned firmware can not be flashed without S-OFF. I believe To update your firmware without S-Off, you'll need to return to stock with an official RUU and get all the OTAs (if your RUU was not the latest version.) Then flash a custom recovery and your preferred custom ROM again.
Another thing S-Off gives you is the ability to flash firmwares for other regions.. for example I have a developer edition 1.32.617.30 firmware. I can only flash "617" firmwares. I cant flash 1.32.401.17 firmware because the "401" firmwares wont match my CID.. but I can with S-OFF.
Also a word about root.... There is no reason to root your phone if you will flash a custom ROM.. This makes 0 sense since you will root a ROM that you will then proceed to delete. The only reason to Root is if you plan to stick with the stock ROM, or if you want to backup some things that require root before you flash a custom ROM. Root is not required for flashing a ROM.

No
SunShine is our bootloader unlock/s-off tool for Motorola and HTC phones. We currently support most HTC phones, and Moto X (2013), MotoG (2013) and Droid Maxx/Mini/Ultra on Android 4.4.3 and lower. All modern HTC devices (m9 m7 m8 e8 Mini2 remix dna etc) devices are supported up to 5.0.1, as long as they are rootable.

"as long as they are rootable" means you have to already have the bootloader unlocked Twrp installed and Rooted on the M9
So if I wanted to turn my T-Mobile HTC one m9 into a dev model I just need to unlock the bootlooder and root it.and also get s-off.Is that correct.I thought the dev model had more frequency bands for you can get service in more areas.Is this right or no? Thanks In advance!!!

You don't need root for that. Just S-off.
You can flash the dev edition RUU, but it's not going to disable/enable any bands. That's all hardware. You also lose wifi calling.

OK I never use Wi-Fi calling.so does the dev edition have more or different bands or are the band's the same as the T-Mobile version.so it Is possible to duplicate the dev edition to make my T-Mobile model the same as it. Thanks

Having S-off means you can update the phone firmware (think: bios) without having to wait for a.carrier OTA. This ability is different than unlocking your bootloader which enables you to flash a ROM. Without these two things, the only way to update your phone is to wait for the carrier to get around to it. For example, we who also own M7s already are running LP, while the rest of the AT&T customers wait l.
One thing I would encourage you to do is to READ THE GUIDES THOROUGHLY, because your questions clearly indicate you are not familiar with the process or what you are doing, and one mistake can possibly brick your phone.

Yeah, the dev edition has the exact same hardware as the ATT model. The bands are different. If you want to use the phone on Tmobile, the tmobile version will be the most optimized.
The most you can do is flash the dev edition RUU.

Rooting methods

Guys, just got this brand spanking new. It's my first LG and from what I'm reading it's not easy to root this thing. I've read through the forums and wanted to ask if unlocking the boot loader through LG then installing recovery and flashing supersu for gaining root is safe for my phone or should I go through the low effort methods and others... Very confused...
I've got the H815 ...
I've attached a screen shot of my software too to be clear as to what I'm running...
Sent from my LG-H815 using XDA Free mobile app
If you have the 815 model, then it's perfectly safe. I just did it in the morning. Unlock, flash recovery, flash root.
Okay so I basically unlock through LG, flash the recovery and then flash super su through it and that's it right?

Also needed to ask, will unlocking the bootloader reset the phone or wipe it?

splashscreen can be flashed - install twrp, if the bootloader is locked the fastboot flash will fail with no harm done. If it installs then you are unlocked
