Can't Flash TWRP - General Questions and Answers

Hi friends, I own one Asus Zenfone max pro m1 and I recently wanted it's bootloader to be unlocked and I tried the unofficial method but didn't worked. So I chose the official method. It wasn't a good experience because I was successful after several attempts. Don't know why... But after installing and unintalling and then reinstalling the unlock tool several times somehow I managed to unlock the bootloader. Now it's showing fastboot mode instead of csc fastboot so I believe it's bootloader is unlocked.
But as I tried to flash twrp using Bugjaeger app from another phone(since I think I'm having issues with usb 3.0 port on my lap) it's showing "Flashing not allowed in Lock state".
How can I be sure to know if my bootloader is unlocked or not? And whatif I flash rom directly(using adb/fastboot) without twrp with Corvos OS? Will O be stuck on a boot loop?

I finally came to solve my problem by trying to unlock the bootloader again and again by official method. And after 3 attempts it was succesfully unlocked (unlocked properly). I could flash twrp without any difficulties and Im on Abhix Rog version now..

OnePlus One OxygenROM- Cannot Unlock Bootloader or Root

Custon Rom after Oxygen has loaded
All,
I have a OnePlusOne and I love the phone. I have had custom roms on the phone in the past and now running Oxygen and not a big fan of it. .I have now tried to Root and unlock boot loader . and it doesn't appear to be working
I have followed the directions from here:
forums.oneplus.net/threads/guide-oneplus-one-how-to-unlock-bootloader-install-custom-recovery-and-root.64487/[/url]
when I unlock the boot loader I don't think it is unlocking. I think this because it does not wipe the device
if I go thru the rest of the steps it does load the TRWP and it is rooted
I am just trying to load the Cyanogen rom or something that is clean and smooth
AM I missing something?
I can boot into TRWP
and root checker sais that I am rooted
thanks in advance

If you've had custom ROMs on the device in the past then the bootloader must have been unlocked at some point already. Did you relock it? Check the status with this fastboot command:
Code:
fastboot oem device-info

[Q] Nexus 5 6.0.1 (MMB29Q) not rooting & no SuperSU

I’m currently using NRT 2.1.4 and i’ve tried rooting my device a few times now and it never installs SuperSU and I can’t boot into TWRP as it shows the android laying down w/ the red exclamation, which is odd since it does go into TWRP during the process of rooting...
But I do not have TWRP installed because of the NRT process
Steps I have taken:
Unlock Bootloader
Flash stock + Unroot (Latest version MMB29Q)
Root & Custom Recovery
When I do the root step, it boots into bootloader, goes in a temporary twrp, then launches normally and says to update SuperSU binaries and check busybox, but neither SuperSU or busybox get added into my app list
It also sometimes says ADB recovery device not found on some attempts..
Is there any way for me to root my Nexus 5?
I have repeatedly flashed the stock with the newest version and still haven’t been able to root.
I have tried relocking the bootloader and unlocking it, but upon unlocking it again, it says that it's already unlocked...?
(Bootloader shows LOCK STATE - unlocked when trying to relock bootloader)
I have been able to root my Nexus 7 2013, but can't seem to get my Nexus 5 to work..
How about flashing TWRP via fastboot, then use the volume/power button to immediately boot into TWRP, and then flash supersu?
The bootloader will not relock?

Yeah, I don't know why, when I try to OEM lock and unlock it says it's already unlocked, which is odd.
But I did the TWRP via fastboot and installed SuperSU that way, thanks.
Glad it worked for your phone.
Help me to unlock bootloader and root
Hello Guys, I want to unlock the bootloader on my N5. My phone is in Android Ver 6.0.2 with Feb patch(Build Number MMB29Q). Please help me in doing so. Also i would root my device, i would prefer TWRP. Please anybody...
Boot the phone into fastboot, connect the phone to your computer, and use fastboot commands to unlock the bootloader, flash TWRP, and flash supersu for root.
Unlocking the bootloader will wipe the phone.

Please see my post. May make it help or not.
When I try to burn rom with TWRP, img burns but it doesn't start and zip gives an error and cannot burn.
When I first burned custom ROM (unofficial AEX), it did not start, so when I deleted the data from TWRP, it seems that I deleted things that should not be erased, so even if I burn it from the zip file, with the error message in the image below I...

Question Allow oem unlocking option missing in developer options

So, i recently flashed arrow os 12.1 on my poco x4 pro (veux) using twrp. Flashing the rom removed twrp and now i cant flash it back because fastboot says that my bootloader is locked...
Of course, it isn't and the problem is that allow oem unlocking isn't on... I really would appreciate some help because i've been stuck on this rom for a day.
Gonna wait for some answers, thank you.
In the first place, flashing the rom shouldn't relock your bootloader. Can you please reboot to fastboot mode and use mi unlock tool with the same account you used to unlock bootloader first time.

Thank you for your response. Sadly i already tried that and the tool says that the phone is unlocked.
I'm trying to reflash stock rom via EDL mode, but i always get some error.
By the way, when using fastboot getvar command, it says that my bootloader is locked.
So, i recently bought a poco x4 pro (veux) and flashed a custom rom using twrp. Sadly, the rom's recovery managed to overwrite twrp and when i tried to flash twrp back, i could not flash it because fastboot said my bootloader wasn't unlocked. When i tried to unlock the phone again the xiaomi tool said that the bootloader was already unlocked. So, i used the getvar command which said that my bootloader was locked. So, i remembered that i didnt turn on allow oem unlocking in developer options. Sadly, when i looked for it the setting wasn't there. I tried using Edl mode to go back to stock but with no success. I always get some failed to read hello packet error. Can someone give me any help? Im kinda getting desperate...

Go to service centre if it is critical. I have never seen such case so i couldn't help. I am afraid that you would have to pay the service centre people money for reflashing your device.
Also have you tried flashing fastboot ROM (MIUI) through fastboot? Also try to flash stock recovery rom via the recovery you have now currently.
Another thing you could try is using the Xiaomi official flashing utility (which is not unlock tool) to flash stock rom which does not require OEM unlock.

Thanks for the reply, i will try what you said.

Samsung Note 3 SM-N9005 with twrp installed can't flash lineageOS android pie.

So I Was Trying To Unlock My Note's OEM By Flashing A custom rom, But TWRP Says Failed, Any Help?
What steps have you followed to unlock your bootloader?
Enabling the OEM Unlocking toggle is the first step. If you are unable to do this, the bootloader cannot be unlocked and flashing custom firmware is not possible.
I Still Haven't Unlocked It, But I Flashed It With Twrp And Rebooted Then LineageOS Wasn't Installed, Download Mode Hasn't Been Affected.
(UPDATE) Fixed The Failed Problem And Rebooted With Lineage Os, Download Mode Still Hasn't Been Affected
