How to see if TWRP is installed? Bootloader is unlocked - T-Mobile LG V10 Q&A, Help & Troubleshooting

Hi guys
Long story short I bought a tmobile unlocked v10 off swappa that was rooted. I had the seller return it to stock. The bootloader is still unlocked but I'm not sure if TWRP is still there. Im a noob to rooting with the bootloader unlocked. My previous phone was a verizon galaxy s4 with safestrap and bootloader locked. I flashed tons of roms on there but it was different with safestrap and not touching the bootloader. Im not sure how to proceed with my V10. I have adb installed on my computer and it sees my device. Any tips or directions would be greatly appreciated. I'm reading the guide to easily root the v10 but I'm still nervous on how to proceed. If someone could guide I would really appreciate it. I'm just not fully versed in bootloader and fastboot so I'm a little confused.

should i do these commands in the command prompt? I have twrp-2.8.7.1-h901.img in my C drive adb folder.
Instructions:
If you have issues with adb or fastboot follow this post: HERE
If bootloader is unlocked:
reboot into bootloader
Code:
adb reboot bootloader
fastboot flash recovery twrp-2.8.7.1-h901.img
fastboot boot twrp-2.8.7.1-h901.img

mods please close this thread I got it figured out. Not sure how to close it myself or if I can

[Q] 2.3.4 software/Unable to Unlock Bootloader

Hello everyone. I am new to the world of android, but I'm a quick enough learner. Here is my specific problem:
I have an AT&T Atrix 4g. It is currently superuser rooted. It is currently running Android ROM 2.3.4.
Shortly after rooting the device, I downloaded ROM Manager and successfully installed through the application Clockwork Recovery. I tried to select the option to back up the current ROM (the stock android) on my SD card.. however, during the load screen, I got an error message stating
"Failed to boot 2
Starting RSD protocol support"
So doing some research, I came upon the conclusion that the reason I can't backup or really do anything with ROMs is that I needed an unlocked bootloader.
I went to Atrix4ghacks and followed the instructions on how to unlock bootloader and install permanent recovery.
This is the critical part: When I entered into the command prompt "fastboot oem unlock", instead of proceeding normally I got the return message:
"OEM unlock is not implemented"
Again, did a google search and read that Android 2.3.4 on Atrix 4g does NOT allow unlocked bootloaders.
So, the questions that I have that result from this are:
1.) Can someone here confirm that, in fact, I am unable to unlock the bootloader on my phone?
2.) If so, is there a viable workaround that is both reasonably safe and not overly complicated? Please note that I have no backup in case something goes wrong, leading me to
3.) Is there a way to backup my stock 2.3.4 ROM without an unlocked bootloader?
4.) Can I revert safely to an older android version that supports unlocked bootloaders?
5.) Can you actually install new ROMs without an unlocked bootloader?
6.) Am I totally screwed?
HUGE THANKS to anyone who actually bothered reading this, and even more thanks to anyone who can answer/point me in the right direction. Much appreciated!!!

Thanks a ton for that link. I'm sorry to ask once again, but I'm very wary of possibly bricking my phone... so I must ask: Is your solution possible with 2.3.4? Or will the phone softbrick?
If you did the Over The Air (OTA) update to 2.3.4 then yes your phone will softbrick after flashing the bootloader. Re-enter fastboot and issue the unlock commands and everything will be fine when you reboot.

How do I re-unlock my bootloader?

Hi everyone.
I'm S-off, SuperCID, 4.16.401.9 firmware, and I re-locked my bootloader while troubleshooting an adb problem.
Is there a simple fastboot command that'll unlock my bootloader again?
I can flash recoveries via the Flashify app, but I can't do much via adb anymore.
Thanks!
How did you unlock it the first time? HTC Dev Im assuming,should still have the unlock token bin file...thats run from bootloader via fastbootusb command...This should be in Questions and Answer forum...??

That's weird.... I thought I posted this in the Q&A forum. I was just in there looking for it and I thought it'd gotten deleted or something. Oh well.
Mods, please feel free to correct my goof.
I didn't use HTCDev to unlock. I just did Sunshine and it handled everything. S-off, unlock, and root - Talk about painless! After that I installed a custom recovery (Philz) and I was off to the races.
So I decided to SuperCID my phone so I can install whatever I want. No problem.
Then I tried to install 5.0.1 firmware (4.16.1540.8) so I could run SkyDragon, but the firmware posted on page 1 in the thread would not install- 4.16.1540.8
Kept giving me "FAILED (REMOTE:24 parsing android-info fail)"
I was able to install 4.16.401.9 with no major headaches, once I found a sensible upgrade path. That one is working fine, but I don't understand why 4.16.1540.8 would not install.
After googling the error, I found a post from Scotty a while back that said the phone wanted to see a stock recovery, locked. So I thought I'd throw the old recovery back on and do the 'fastboot oem lock' command . I didn't think it would impact the phone's operation since it is S-off. Well, the command worked, but I still wasn't able to flash the dang firmware I wanted to my phone.
So now I'm S-off, locked bootloader, PhilZ recovery (put it back on with Flashify), SuperCID, on Lollipop, and I guess everything is ok. But I still don't understand why the phone wouldn't take the firmware.
Any ideas? Thanks in advance.
If you ran sunshine on it,you can run it again i believe on that same device. It should unlock it again,if not then can try htcdev as it also uses fastboot to unlock as long as you can get adb to show needed code.

In the past (at least on my One X EVITA) my understanding was that s-off meant that all security was bypassed. Meaning that bootloader check was effectively bypassed.
This isn't the case for the M8. From what I can tell a LOCKED bootloader still prevents you from flashing anything that isn't signed (anything "unofficial") even if s-off.
However, having an UNLOCKED bootloader doesn't seem to affect anything while s-off. Meaning you can do things like RUU when UNLOCKED (which normally needs to be LOCKED or RELOCKED if s-on).
In short, I don't ever recommend relocking the bootloader if s-off on this device. There isn't any reason to, as far as I can tell. Meaning, having an UNLOCKED bootloader doesn't prevent you from doing anything. However, a RELOCKED bootloader does (even when s-on) prevent some things.

can't OEM unlock!

hey everyone. trying to OEM unlock the TWRP bootloader. When I type "fastboot OEM unlock" it will reboot into TWRP bootloader, and nothing unlocks. I know this because when I type "fastboot oem device-info" it says "unlocked FALSE".
I have OEM unlock and USB debugging enabled.
This is a phone with previously successfully installed CM13, and now I'm trying to revert to stock/unrooted. I can't seem to flash the recovery at all here because I can't get the damn thing to unlock.
Any ideas?
Did you lock the bootloader ? If your flashing Roms and custom recoverys imagine its already unlocked. Bootloader won't lock itself. If you want full stock just flash any OS2 firmware with twrp. You can worry about stock recovery after. I would just leave the bootloader unlocked won't hurt anything.
I had the same issue not long ago. Finally, i used the mega unbrick guide, but warning, all the data is lost
Ps: Sorry for bad english
hey, thanks for the response. I have been following the following tutorial (and others similar for installing CM13):
(great, website won't let me post it here... it's the unlockr oneplus x guide)
so yes, I originally flashed the stock recovery and replaced it with the one from the tutorial. There were a few hiccups during setup, which may have affected why I can't easily update nightly now, so now I'm trying to revert to the unrooted stock state so I can try from scratch, hopefully fixing the issues I'm seeing now. The problem is that I can't flash the recovery using the stock recovery... I can't even update the damn recovery because it's locked. Is this what is meant by a 'soft brick' ?

I'm Having Trouble Rooting through Custom Recovery

I have wanted to root my phone for a while but one-click roots definitely do not work. So in my research I've found that using some kind of custom recovery is the next logical step. In doing more research, I downloaded the adb and fastboot tools but then found myself unable to unlock the bootloader. My theory is because I don't have oem unlocking checked, for the reason that it doesn't show up in developer options. USB debugging does though, so I have that checked. At this point I'm at a loss. I've tried all kinds of commands like fastboot oem unlock or trying to go to the bootloader through recovery mode and through commands. None have worked, and the only command that seems to do anything is adb reboot recovery. I was wondering if anyone had any ideas on what I should do next? Thank you!

Check your phone, is it international model? What carrier did you get it through, Verizon & AT&T BL's are usually OEM locked. Which can be a drawback.

It was for straight talk I believe. And from what I can tell it probably is OEM locked. If it is, does that mean it is impossible to root?

Question Noon question re boot moto g play 2021

Hi, have been reading posts here, but I'm trying to get a grasp on all involved to root my phone. I am pc literate but this is all new.
One site I got instructions on, https://www.thenextdroid.com/root-motorola-moto-g-play-2021-pc-via-magisk/, does not mention unlocking Bootloader with magisk~ just run magisk. Zip, Android it's rooted.
So my question, is that does the magisk v23 unlock Bootloader for you, or was that nugget just left out of this article?
I am obviously not new to this so would appreciate any counsel on this~ it does seem too easy 2 be right, but would appreciate some verification.
Thanks in advance

For unlocking the bootloader I followed the instructions from Dr.E (Max Lee) here
it still works for all Motorola devices currently and I used magisk to flash my stock firmware boot.img to root I also installed a twrp image from this forum I went into 2 bootloops trying to root this phone but I can say it's way better rooted than locked

The bootloops were caused by my own negligence and trial and error
