Use fastboot to reflash the usual and x from ics. There's a thread with a link if you haven't already downloaded it.

[Q] Security error on an unlocked bootloader?

I had unlocked the bootloader of my p768 sometime back by flashing onto a p760 firmware and then i returned back to a nandroid backup of my p768 v20A
With the nandroid restore, I got my old recovery back(the one which is installed by the l9 recovery installer app) and everything normal
I wanted to use the touch recovery which is in this thread.
So i replaced the recovery in my nandroid backup with this one and tried to do an advanced restore of boot.
Now I have a security error.
Isnt the error only locked bootloader specific?
Update--I used the LG flashing application. I had to use the recovery phone option to make it work. It flashed V20A on my phone. When I did the bootloader unlock check in the hidden service menu(3845#*768#) it said "lock"
but now when my phone is in SW Update mode, it says bootloader status:unlocked

Sure I will try it in the evening.
You can definitely Unlock it using the HTCDEV process , I have a done this. Any ways if you are able to flash a ROM then there is no reason to get it Unlocked, more over S-OFF gives you full control over the device but again it also increases the risk of getting your phone bricked so make sure you use it wisely (knowing what you flash) , so I will say why to beg HTC for some thing they have already provided.
One more thing S-OFF device means you dont need to flash boot.img separately so you dont need to use your PC to flash roms no more.
Waiting to know about your progress on flashing the ROM ..

I have now successfully flashed a Rom..initially I tried it without flashing the boot.img and it entered a boot loop.
Then I installed flashify and flashed boot.img that came with the Rom. Then the Rom is working now.
The boot loader is still locked. Has twrp .

so you mean to say you failed to install the boot.img from the custom recovery ? well that is weird, one more thing since you were in boot loop how did you manage to install flashiffy !
if you may please include the complete flashing steps , will be helpful for my experiments.

Initially I flashed the Rom alone and it went into bootloop and all buttons became unresponsive .so I waited till the battery ran out and the phone switched off. Then I recharged , entered recovery by vol down + power button.. I had the backup there . So I restored back up.. then phone rebooted normally.. and I flashed boot.img by flashify just because I didn't know any other method... Then from recovery I wiped dalvik cache and system .. flashed the new Rom.. reeboot and fine..
Feel free to ask for any more clarification..

Flashed stock ROM but not booting up

Model:XT1521 Retasia(Indian)
So let's get on with the story
I own a moto e 2 4g variant. I unlocked the bootloader of the device,installed a custom recovery and flashed a custom ROM. Everything went well;I was trying a new ROM almost everyday(5.1.1 and 6.0.1) until one day when I decided to go back to stock ROM.I downloaded the official 6.0 stock ROM,installed it and started the device.The phone booted,went straight to recovery and showed erasing.The problem starts here.It showing eraseing and rebooted after some time and I thought that it's going to boot up into stock 6.0.But I was wrong.The phone booted and again did the same thing and this went on in a loop.So I decided to try it once more.This time I did two more things prior to installing the ROM;
Fastboot erase all
Fastboot erase system - w
Till then in bootloader it showed official in software status.But after those two erase commands it started showing modified.
Even then the result was the same I.e.showing erasing and rebooting.So I thought that I will go back to custom ROM for the time being.all went well,phone booted up but there was no signal.The phone was not accepting any Sims. I went to bootloader and immediately found out the cause.It was showing not found under baseband.So I seperately flashed a modem but to no luck.As of now I have tried all stock rims available(5.0.2,5.1.1,6.0) but the device is not booting up.
Any help will be highly appreciated.
Thanks in advance.
This happened to me with CM13, the same thing happened with the baseband number, and I couldn't even enter in the recovery, so I had to manually flash the Stock ROM via adb. It happened to me again when I tried to root my phone even with the systemless root, the phone just doesn't boot up, I'd recommend you to flash the basebands found in the forums, if that doesn't fix it, you'll have to manually flash the stock rom via adb or you can use the easy tool, it's fairly simple if you follow the steps, I'll leave the links bellow.

Used the flashing tool.But in every mode of flashing,the bootloader flashing and boot.img flashing is showing some error.But rest all are flashing succesfully.Still in bootloader it is showing baseband not found.And when I boot the device,the bootloader screen comes up,followed by a black screen and the cycle repeats.Any help would be appreciated.
Edit:My moto e 2015 is a LTE RETASIA(Indian) model.In the baseband link you provided,XT1521 RETASIA version's baseband is not available.

One Plus X soft (?) bricked

Hi guys,
Before you say again a topic on a non bricked One Plus X, I would like to let you know that I've checked and try almost all of the tutorial I've seen on xda and one plus forum.
I was on CM14.1 with this ROM : https://forum.xda-developers.com/oneplus-x/orig-development/rom-cyanogenmod-14-onyx-t3452150
Unfortunately, I made the 25-12-2016 update and it totally broke up the phone..
I download the OnePlus X OxygenOS 3.1.4 on the One Plus website. So I flash it on the stock recovery, it tells me "Install success" then I reboot and it stays on the bootlogo.
For information, I can't access the oem unlock menu if needed, but when I ask the oem device info it says unlocked. The phone is detected by the computer sometimes with unknown device and sometimes correctly with the qualcomm drivers..
I have a back up made from TWRP, I can access the device by the fastboot mode, it seems that all the operations written here worked but it doesn't install or even boot on TWRP..
Thanks for your help guys.

I'm not even using TWRP, since I can't boot on it.. But I tried to flash the twrp-3.0.2-2 from blue spark v41, after the installation via Flashboot, it doesn't boot up on the recovery..
So after flashing TWRP you use fastboot boot recovery.img and nothing happens?

If you did not unlocked bootloader properly then also you might face the problem...

Start by seeing if you can fastboot flash stock recovery from any 2.X.X OOS. Then fastboot flash twrp 3.0.2. If your on new bootloader meaning latest ROMs or OOS3 then you need to boot into 3.0.2 and from there you can flash IMG of twrp 3.0.3. Make sure you boot right back into recovery after flashing any twrp or it won't stick. This worked for me when I lost my recovery twice but always remember at your own risk. Not responsible if you make your phone into a paper weight.
Fix It!

how to root asus zenfone live zb501kl

I have been searching in the internet for hours, trying every method i could understand and none of them worked. the main problem is the official bootloader unlock tool provided by asus is not working, it just restarts the phone and it is still locked. one solution is flash a custom recovery without unlocking phone and another way is unlock without the official app or maybe root without custom recovery, i would be happy if someone explains a way to root this phone.
indeed. the official bootloader unlock is not working and just restarting with no changes.
Then i tried to flash TWRP via fastboot it says Ok but no TWRP when I proceed to recovery its only stock recovery.

I suppose that you've already turned developer mode on and enabled the USB debugging.
Did you either reboot the phone by yourself or it did that automatically after flashing twrp? There are some devices that just restart and get the official bootloader back. This auto restart overwrites the bootloader.
Some people say that after flashing twrp you must unplug the device and then reboot directly to bootloader by yourself, holding the power and volume up buttons . Have you tried it?
