Bootloop and no recovery...

So I feel like I am pretty experienced when it comes to the whole ROM/Root scene, I've had the OneXL, Galaxy S3, and Nexus 4.. but I've always had a difficult time with the One XL and ROMs... I always seem to run into major problems.. Right now I can only access the fastboot area of the phone, it will not go into recovery (i have even tried reflashing recovery but no luck) and no matter what, it bootloops constantly. I had ViperXL running fine on the device but I tried to install ElementalX kernel for the first time and now the phone is Kaput.. Any ideas??? Could this be a semi-brick?

did you specifically try to go into fastboot and fastboot flash recovery recovery.img
?
because this phone is pretty much either "it's reading qsb mode in device manager bricked" or "i don't know what i'm doing and cannot figure out what to do next NOT BRICKED" (i'm not rippin on you; if you pull up my history, it even happened to me once and i had to make a baww thread for someone to help me figure it out. turns out, don't click factory reset in bootloader.) there is one other way, but it involves acceptin the OTA with your CID having been changed

Actually, I was just about to post that I fixed it!! I relocked the bootloader, then unlocked again(i thought maybe it would wipe all my data for me, and it did!!) So I then reflashed the recovery and got into it, reformatted the USB mount in windows with FAT32 and then placed a new ROM onto the device. And it booted right on up!
By the way, this ind of thing happened to me too before... but I never had to do the bootloader thing.. Thanks for the input though!

Boot-looped One mini!

Hey guys and guyettes!
I somehow managed to put my One mini into a boot loop!
None of the options on the fastboot menu do anything other than turn the screen black and then go back to the boot menu... If anyone has any ideas on how to fix this it would be greatly appreciated!
And before anyone asks for whatever reason, no it is not rooted!
Things I've tried:
- Using ADB and SDK to unbrick it
- Hard resets, recoveries and factory resets
The last thing I did before it started the loop was install King of Thieves (a game).
Before the loop it ran out of power so I plugged it in and it went to the menu like it usually does then it just started too loop!
Thanks for any suggestions

I'm currently chasing the same thing on my wife's phone. This is the 2nd time this has happened. (the first time was replaced by factory warranty). The ROM and everything is completely stock so I'm trying to unlock the bootloader using the HTC dev tools and I can flash the Unlock_code.bin but the screen never prompts me to actually unlock it... I'm hoping someone has a tried and true way of fixing this.

I have the bootloop menu which suddenly appeared for no apparent reason seeing as I haven't rooted the phone. It's an annoying problem that I see many people have except most people I see haven't quite got the same problem as myself...

Same issue...
I have a customer's phone, having the same issue. The customer brought it to me like this and I thought I would try to repair it. He is mentally challenged and so I really wanted to help him. But it's doing exactly what the OP stated. I even tried the same things before I found this thread. Unlocked the bootloader (but it did not actually bring up the screen to unlock the bootloader, the WinDroid Universal Toolkit simply stated it was unlocked). And yes, I did acquire the unlock.bin or whatever it was called.
So the phone will do nothing but reboot. I'm not sure how it got this way or if it can be fixed. That is why I am here.
Any ideas?
Thanks!

probably this is the case

Rooting LGMS631 (Metro) Running 6.0

Hi there,
I know this is probably redundant but I've been searching these forums and I'm a bit overwhelmed. Mainly I am trying to discern whether I need to factory reset my phone before I root it or not. If anyone would be kind enough to break it down for a rooting noob, but fairly tech savvy chick, I would really appreciate it. Or just direct me to the most applicable thread for my situation. I have a PC running Windows 8.1 also, if that helps.
Thanks!!!

Factory reset is not necessary.

i tried following the guide , igot the bootloader unlocked but when i tried to do the flash recovery.img it kept saying it couldn;t find the directory. i moved the img file to the same place as where the adb is installed but that didn't help. i ended up rebooting my phone and it was in oem state. I installed a backup for now but I tried to attempt it again and i couldn't get it to come up in the adb devices anymore. Advice?

never mind

Warning: Do not flash the google assistant

I flashed the Google assistant some time ago and everything was fine but yesterday I decided to do some minor build prop edits and accidentally bricked my phone. Now that's fine because they have multiple ways of unbricking the T-Mobile LG v20. But when I tried to unbricking it using LGup nothing works because it registers my phone as a pixel and now my phone can't be restored. So take it from me..Don't do it!!! It isn't worth the loss. I have a brick now. An official lg v20 brick. Sigh
EDIT:
IM EDITING THIS TO ADD WHAT I DID.
Here's the story
I was trying to revert to stock with the build prop so I could upgrade my phone. so I edited the prob and removed the lines I added to get Google assistant in the first place but it crashed and when I entered TWRP to push the build prop. When that didn't work I flashed the stock tot file which got my phone working but I wanted to upgrade so I found the page in XDA to flash the kdz with LGup which I was doing but half way through it failed and Twrp was gone which started this snow ball effect.

Do you not have TWRP you can reboot into, and re-flash a backup or new ROM?

Nope, the only thing my phone does it boot into the mode where it says "Firmware update" mode. I really think I destroyed my phone.

That's actually a pretty good idea. I'm going as soon as TMobile opens.

I had the same problem. ADB didn't recognize my device to run command to reboot recovery. I found that ADB did pick it up while doing a factory reset. Even tho it was the original LG factory reset screen it would use TWRP to perform the reset but would automatically reboot after. So I had a command window opened with adb reboot-recovery typed then I rebooted into the original factory reset and selected yes twice. As soon as TWRP screen came up and I heard the windows chime recognizing the device I hit enter in command window to reboot recovery and it rebooted into TWRP normally where I was able to restore from backup. If you time it right you can get back to TWRP. Hope this helps

That is very strange, I recently bricked my phone to the point where I didn't have a system at all on it. When you boot to firmware update mode (power + volume up) and pluged it in LGUp recognized it instantly. You have the correct DLL for your device right?

My issue was that when I flashed the assistant mod it turned my device name into " google pixel" so when I hooked it up to lgup it read it as a pixel and failed the restore every time. That was the issue I couldnt change the name of my devixe back to the v20.

I disnt have anything on my phone. No twrp and I couldnt install it. The assistant mod changed my device name to PIXEL and when id connect it to the pc it read as a pixel and failed every update I LG V20 I pushed to it..that was a new type of brick lol. But I told t mobile that if I what happened and I got another one.

These old assistant mods would be taken down. The only thing needed to enable it without spoofing a phone as a Pixel is adding "ro.opa.eligible_device=true" to build.prop, and the Google app updated via Play Store.

That's the thing my phone didn't have a system on it at all and LGUp read it as what it was. When you on the firmware screen it should read based on hardware ID right? Have you tried using LG bridge? Are you on the T-Mobile variant?

This is a contributing factor in why these companies lock bootloaders. People do stupid things because they don't know what they're doing and then others encourage them to just return it and get a new one and lie. Not cool at all. How about don't root your phone if you don't know what you're doing.

WTF! With your logic no one would learn anything.
My phone was rooted just fine. How was I suppose to know that after I flashed the stock build prop my phone was going to stay as a pixel device?? That wasn't stupid of me that was trial and error. Something stupid is if I did it again. No one specified that my phone would stay as a pixel device, go read the instructions and tell me where it says that. Also, I have "Jump on demand" so I used one of my jumps to get a brand new phone..So I paid a price for it. It wasn't just "me lying and getting a free phone" I still paid for it I paid for my mistake and Yes initially I lied but still paid and am still paying for this phone. Plus I have an s7 edge and a Huawei honor note 8 all rooted and have never ran into any issues. Why?? Because I never did what people instructions told me not to do. I always follow instructions. I've been rooting phones since I was a milk drinker all the way back to the G1 days. I'm very careful but if instructions don't cover all the basis then what?? PEOPLE, including me should continue to root and try new things. But you can't blame them if YOU(not you in particular but in general) as a developer make something and can't catch all the bugs(it isn't The developers/modders fault either)..Modding is a giant community of trial and error. The only people at fault are idiots who don't read and do some ****. Other than that we are all out here finding our way with these new devices. So yes, I have a new v20 that I paid for with MY "Jump on demand" plan that is now rooted and unlocked. Now am I going to use the Google assistant mod again?? No, because that would be stupid of me. Now get off my post.
I was just warning people so they wouldn't make the same mistake as me.

Whats the stupid part is how you managed to erase TWRP and lose access to fastboot on your device. Not that your changed something in build.prop. His logic is not flawed, whatever you did to lose access to the two essential parts of having a rooted phone is the flaw here.
Also simply doing build.prop edits should not make you lose access to TWRP nor being able to access fastboot - or did you relock your bootloader?

In stead of assuming what happened with my device how about y'all ask me the details first. But coming off the bat assuming that I just did foolishness is asinine.
I was trying to revert to stock with the build prop so I could upgrade my phone. so I edited the prob and removed the lines I added to get Google assistant in the first place but it crashed and when I entered TWRP to push the build prop. When that didn't work I flashed the stock tot file which got my phone working but I wanted to upgrade so I found the page in XDA to flash the kdz with LGup which I was doing but half way through it failed and Twrp was gone which started this snow ball effect.
So once again where's the stupidity on my part when I didn't know that my phone was still going to be labeled a a pixel after a factory reset? Please, both of you have several seats in the back.
All I'm doing is warning people about what could possibly happen. Y'all can miss me with your unnecessary opinions and comments.

No I appreciate you wanting to warn the community, but you most certainly did not post that story. You posted saying you got bricked from doing edits to your build.prop and then because of using a Google assitant mod you are hard bricked. Post that entire story as a warning because even having your phone appear as a Pixel won't do any harm - but flashing a .kdz and having it fail midway may indeed cause harm. Lack of details causes much misinformation to spread around quickly

My bad I'll edit it. And apologies for the response tone.

It's called taking responsibility. You had a phone with root and did something stupid. Instead of taking responsibility you lie and tell them the phone is defective. That is 100% your fault. I bet it worked fine before you started messing with it. Whatever man I'm gonna let this be but you can bet that when these companies look at the supposed drfrctive returned phones and see they have been tamperred with and that people are being dishonest to get a new phone when they're the sole reason the phone stopped working, eventually they will all say screw it and just lock everything down.
Hopefully you learned from this.

Actually the phone had a few random rebootsa and use to freeze on stock. I decided to keep it because of the note 7 fiasco and I was too frustrated and pissed to return it and then they ran out. So this was well over due. But once again you know nothing Jon snow. And yes I did lie but this device already had issues. Soooo???

S6 G920F stuck on boot logo

Not sure if my phone is a lost cause and only good as a door stop. My phone at one stage would only display a screen asking me to plug into smart switch to recover the phone so I tried that but smart switch wasn't happening. I downloaded the latest stock rom and installed it successfully via ODIN but now my phone will not get past the boot logo. I can only get into download mode, Any advise on if I can get my phone working again?
Thanks

Bro, I've been there and this is why I made an account on xda to see if my s6 (G-920F) can be fixed in any way. Yesterday I had the same thing as you when I tried to re-flash the phone with its proper, latest stock-ROM (UK/EE Nougat 7.0). Given how it hadn't worked, the update attempt through Odin screaming a big "FAIL!" at me, I was afraid I had bricked it completely, so I proceeded to re-install TWRP with Odin by putting the phone in download mode. I wiped the phone again with TWRP and now I'm not sure what I have to do as I am stuck with the UK Nougat bootloader and nothing else on it.
Before this whole ordeal I had rooted the phone and unlocked the bootloader following some instructions from a Youtube video and successfully installed a nighty build of LineageOS, which was buggy as **** (couldn't answer calls, use data, use the camera and a ****ton of apps were just not working). Dumbly enough, I thought I could just remove it through a wipe and put something else back on it but oh was I wrong.
Right now I'd just want to get my phone back to working (like you), as I am out of a job and need to be able to take phone calls with a normal, working phone.
Sorry I couldn't be of much help, but yeah maybe a first step towards fixing it would be to flash TWRP recovery on it and through the terminal, see what bootloader version you have with the command "getprop ro.bootloader". At least you will know the version of the broken bootloader you're experiencing difficulties with and *hopefully* an actual dev from the forums will entertain themselves in trying to solve this noobish puzzle we've created for ourselves.
Seriously, if there is a dev ready to board this crazy adventure with us, please help.
My namesake or username is pretty much a clue to what got me into this position.

I wish it was that simple for me mate, I cant access the recovery menu, I've tried flashing various recovery options but cant boot into any of them. I'm certain I could fix the phone if I could get to recovery. I'm now leaning towards it being a hardware fault with my phone. As you have access to recovery I think you may have more luck with your phone.

Oh dear.
Yeah it does sound like something got deeply ****ed up in this case. I had the luck to somehow get past the smart switch error when the phone died of low battery. As I attached it to the charger I quickly boot it into download mode before the screen would become a bootloop again and that's where I was able to reinstall the latest version of TWRP recovery. After that, I was able to flash a stock ROM of Nougat that didn't have a ****ed up bootloader like I had. Specifically the one from this thread: https://forum.xda-developers.com/galaxy-s6/help/device-5-binary-3-s6-sm-g920f-t3706025
by forumber2.
It's the Netherlands stock-ROM. Not sure if you're from the US and the carrier would be wrong with that CSC, but it was a good bet for me. I got my phone back to working normally now.
Worst case scenario I'd say see if you have a phone repair shop nearby and ask them an opinion on what could be wrong. I'm just an amateur like you.
Still, I wish you the best of luck with it. Maybe there's still some hope. :/
