Can't unlock bootloader no ADB NVFlash not working no APX HELP ME PLEASE :/

Hey friends! I just recently got an Acer a500 as a gift. I went ahead and rooted the device with ICS 4.0.3 but now the problem is I can't get a recovery into the device cause the bootloader is locked, tried really hard to find a solution. I have tried NVflash but it says my device needs the USB drivers, which I already installed. I tried the power button and reset, but nothing happens. Please if anyone can kindly help me? I truly appreciate that!

Please Help! I flashed my phone to Lineage OS and tried to relock the bootloader.

Please Help! I flashed my phone to Lineage OS and everything was working great except android pay. I read online to re lock the bootloader for android pay to work. I did and the phone suddenly died on me. If I try to switch on it wont switch on. It just shows ZTE logo and dies and the red notification light flashes once immediately. If I try to charge, the red notification light wont come up. Its all black. Please help if anybody knows any solution! Thank you!

It's because LOS needs unlocked bootloader. What you're experiencing is it booting into EDL. If you connect it to your computer you should near that chime that something is connected. You'll need to flash the b20 bootloader to unlock it again. Once you do that flash the nougat bootstacks and you'll be back in business.

With the phone connected to the pc, post a screen shot of the device manager screen.

Phone is in bootloop, no access to recovery, locked bootloader

Hey guys,
So the USB cable I was using to flash my fiance's ph-1 to an Oreo beta came unplugged halfway through the flash.
The phone is now in a bootloop. I can't get to recovery mode via VU+pwr or through the fastboot menu. I can use fastboot and my PC recognizes the phone. However, I forgot to tick allow bootloader unlock in Dev setting so I am unable to flash anything to the phone.
Edit: Wondering if there is still a way to get the phone recognized in QFIL with HS-USB mode... I have tried every button combination I can think of with no luck :/
Am I screwed?
Any help is greatly appreciated..

Ask essential for help, they should be able to sort this out. I think you'll have to send it back to them. In any case, please let us know how you manage to solve it.
Good luck

No luck from essential, they told me all they can do is offer an out of warranty replacement for 200 bucks. I really expected better from a company that actively promotes participating in their beta's so frequently online. :/

Doesn't make sense you must be leaving something out??
You couldn't have been flashing OB with a locked bootloader it would have just failed.
use fastboot getvar to check your bootloader status. if it is unlocked then unlock critical and flash the back to stock zip on this thread.
That will correct your issue they even have the OB3 out https://forum.xda-developers.com/essential-phone/development/stock-7-1-1-nmj20d-t3701681
You could even flash it through TWRP recovery as long as you bootloader is unlocked.

Bricked A2017G

Hey Folks, i just bricked My Axon 7 some Days ago. It started randomly a reboot which i can't abort anymore. Everytime the Device get's a Charge does it start again. I can't enter TWRP or Fastboot (Reboots after a few Seconds). Same for the Flash Mode. It is now completely discharged and i don't know how to recover it. Any Ideas?
Think i can't fix this, but asking here don't hurts... :angel:

4th grade unbrick guide here in the Forums. That helped me after i cannot access any Mode. No Flash Mode, No EDL, No USB, No Qualcomm Loader. Axon 7 too.

Lol. I made a guide based on that one but updated, called DFU unbrick, because everybody had to read my comments there anyways to be able to do it. Not sure why everyone still uses the old one ?
@Miustone: If you want, you can try an EDL cable first. A lot of people say that they could get out of DFU that way. (assuming that you can get into EDL/DFU that is). Google my guide, it's called "DFU unbrick", if the EDL cable doesn't work

Thanks Guys! I will take a look on the DFU unbrick and the EDL Cable. At least a blink of Hope for this great Device... Still good as new, would be sad to use it just as a golden Sculpture lol

Hey, sorry for asking but how did you brick it? I am thinking about installing a custom ROM, rooting etc and I would just like to know if it was something in specific so I can stay away from it. Cheers.

Any help with fully bricked device

Hello!
THink I have bricked my phone, but just checking before I go through what I suppose is a long process with oneplus.
Looking for any help. I had a working device - unlocked bootloader and installed TWRP and magisk using MauronofrioTool. ok - however, I found out I couldn't use a fingerprint security option on that would have been anoying. So... Long story short. I used MauronofrioTool to relock bootloader. Oops - so that didn't work. THen found out I couldn't do anything except stare at g.co/ADH message on my screen. Couldn
't get to fastboot or TWP. ANyway, so I managed to up and down volume and enter into TWRP. Was still connecting to the tool, so I downloaded factory Zips and tried to install via tool after unlocking - Seemed to be working ... but it stopped mid way through a process and hasbn't come back! NOthing at all. I wonder if I could have triggered an OEM thing? ANyway - literally nothing no buttons work no screen action. I see a QUSB_BULK_CID:etc number when connecting the phone, but that is it. No fast boot or any other actions available.
PLease, pretty devastating, Anyone know if I can do anything?

I'm no pro but I use this tool which helped me:

Thank you. I feel I am little past this stage now though.. Also trying the brick reprieve software . Just can't get my computer to recognise the phone now. No ability to get to emergency download path - think it is my crappy cihinese pc (old Huawei tablet basically) or Windows via apple that have me stranded.
**********SOLVED
THe crappy Chinese language Windows tablet worked as the unbrick OP said WIndows would. Must be a kink in the Windows via Mac that could get me into the situation, but not out.
Very relieved... Even though I still am not 100% sure what I actually ended up clicking to get it to register and connect with the unblock tool (which of course was in Chinese) hahaha.
Cheers
CHeers though

Glad you got it sorted out! Cheers

Need Help, please
Just received my OnePlus 8 pro, decided to Root and unlock the bootloader---this went fine.
I then went and upgraded to Android 11 DP3.
I'm now only able to get into Fastboot. at points it will try to boot but only get to the logo screen and then goes black.
When the phone boots up, it goes to Qualcomm CrashDump Mode.
I've been attempting to solve this for half the day with no luck. I've tried Msmtool, but it doesn't recognize the device, even after loading drivers again.
Is there a way to load a ROM from fastboot mode?
Hoping someone can assist, this is super frustrating and I would appreciate any help, please.

Thanks so much. I ended up getting Msmtool to work. Although my device wasn't on (black screen) and it didn't fully show up in the tool, I decided to start the process anyway and it began to load.
I've been on here for over 10 yeas (XDA) I've just lost my account info and made a new one.
Thanks for taking the time to respond. Much appreciated.
