Are there any ways to hardreset a bootloader locked phone with fast boot? - General Questions and Answers

Hey everyone,
I have an LG G5 and I'm trying to hardreset it. I can't turn it on because it always goes into "incompatible module" mode, telling me to change the battery. The power button also doesn't work anymore.
I have however managed to get it into fast boot mode. From there I tried to use
Code:
fastboot erase userdata
but it says that the bootloader is locked. I checked with LG and they said that my particular phone (from Australia) can't officially be unlocked.
Now I'm looking for a way to either unofficially unlock it or to wipe all data with fast boot without having to unlock it. I can't use adb because it somehow doesn't recognize my phone, fastboot does.
Thanks,
Josh

[Q] Nexus i9020T stuck on unlock bootloader

I have an i9020T that is stuck in the Google boot loop. I was given this phone in this state so I am not sure how it happened. I can volume+ and power and get to fastboot. When I do a fastboot oem unlock, the screen changes on the phone to confirm I want to unlock the bootloader. I use volume+ to move to Yes then press the power button to select.
The PC terminal shows the little dots as if it is working on it. After 9 hours, the phone's screen remains on the Unlock Bootloader? screen and the PC terminal has Failed with too many links.
I have tried with the Android ADB Interface driver, the Android Bootloader Interface driver, and the Samsung drivers. I have removed the drivers and downloaded PDAnet, put the phone in fastboot mode, connected to the pc and let PDAnet install the driver (although it cannot install PDAnet on the phone). All resulting in the same outcome.
If I type fastboot devices, it returns the serial number that is displayed on the phones fastboot screen. It will not fastboot oem unlock.
I have searched and read as much as I can find on this and other forums. It appears this has happened before but the threads I have found seem to stop without concluding if there is a solution or it's a lost cause.
Anyone have a solution to this? Or, is this phone just a brick?
same problem here, can anyone know how to unlock the bootloader or even revert to stock ROM with locked bootloader?
Also, is it possible to flash official ROMs, any of those with locked bootloader?
I never flashed any custom or other ROMs with my phone, and it just turned out like this

[Q] Bootloader unlock disclaimer not showing

I have a HTC One MIni that is stock in a fastboot loop every time I turn it on. I can't get any option from bootloader to work. So after doing some reading here I was going to unlock the phone and try to fix it but I can't unlock the phone. So fastboot was able to get the code and I went to htdev and get the unlock.bin file and I can run it with fastboot and it says it is all good but the disclaimer that it is supposed to come up after this on the phone, never comes up. I thought maybe restarting it would show it is unlocked but no luck. So I'm stuck with the phone only booting on fastboot mode and not being able to unlock it and therefore can't install anything to fix it. Is there a way I can fix it?
Thank you

[Q] Moto G stuck; recovery fails from boot menu: Can I reflash the stock firmware?

I have a Moto G that has gotten "stuck", if that's a good description. If I start it, the initial Moto splash screens go fine and then it becomes a dark screen but backlight On and just stays stuck there for ever. (Is this what is called a boot loop? Not sure)
By using the Power + Down Vol key combo I did manage to get it to the boot menu. Unfortunately the Recovery Option there does not work. Shows a quick Moto bootup splash screen, then Says "Boot up failed" and falls to the boot menu again.
What's my best bet to recover from this?
I did install adb + fastboot on my laptop & then connected the Moto G with a USB Cable. fastboot seems to work. I could get the phone to reboot, and some other basic diagnostics. e.g. "fastboot oem get_unlock_data works". "fastboot devices" also shows my device Serial Number correctly. But I want to be careful before I issue any further erase or flash commands so I thought it best to post on here. What is the logical next step in the debug?
"adb devices" did not succeed.
The phone had the original Google / Motorola software so far and I'd never even attempted to flash it etc. Only whatever automatic updates got pushed by Google / Moto / Carrier over the network. Right before this happened I was in a call and got a bunch of pop ups saying Application xxx was being shut down.
The phone is out of warranty. It is still locked, but when I enter the details on the Moto Website it says it can be unlocked. So I can proceed to get the unlock codes etc. if that helps.
The exact SKU is XT1033. Boot menu says (Version 41.13; Battery OK; Device is locked; Status Code 0) if that is of any help. Was a Dual SIM phone on a GSM Carrier.
Tried issuing the commands
Code:
fastboot erase cache
fastboot erase userdata
Both don't seem to have helped at all.
Any other ideas?
To flash anything you first need to unlock bootloader. Doing that erases all your data including internal memory. Then you can flash a recovery & a custom rom.

Thanks @Legolas!
I did not realize that. So I guess if I just tried a flashboot flash command it would fail since my phone is not unlocked at the moment.
Luckily I can get the unlock code from the Motorola site. I will proceed to do that then first and subsequently try all the other steps needing flashing.
What happened? Did you manage to boot it up?
@carefulcat : i have a similar problem as a well.let me know if and how you managed to fix it

No luck yet. If you find any ideas let me know!
@carefulcat :
Check out my thread @ http://forum.xda-developers.com/moto-g/help/moto-g-bootup-problem-recovery-mode-t3122492
The only difference I find from what you've shared is that both of us have different bootloaders.
Let me know if this is true.

Indeed. Very similar problems. Could be identical.
I've, in fact, even erased via fastboot & unlocked via motorola's site. Hasn't helped so far.
I haven't had the stomach to download a 500 MB stock firmware yet.
Who do you think our bootloader is different?
@carefulcat :
Well,I am on an unlocked unrooted Android L 5.0.2 XT1033 Asia Retail Edition (upgraded via OTA) which has Bootloader version 41.18.
You've just cleared the ROM it seems.
Unlocking the bootloader will wipe off all the data from your device.
It seems yours is still locked,you have the unlock code but didn't use it.
Which OS did you have?Exact version,region and type of upgrade.
And which commands have you used till now?
If you're clear with the basics try stocking a Stock Flash ROM (depending on your bootloader and previous OS) or custom recovery like TWRP or CW.

[HELP] Softbrick due to FRP Lock?

Hi there,
apparently I screwed something up while trying to prepare my 6X for Lineage
I did the OEM unlock but FRP Lock is still active and somehow this prevents me from doing anything else.
The combination of problems seems quite special, I've found (and tried) a lots of tipps for softbricked devices here but unfortunately none of them worked for me.
When restarting I get the warning that the device is not secure and will boot now - however it is stuck on "booting now" until the battery is drained.
It starts into Android when charged again but on every restart it will be stuck again.
When in "booting now" only Vol- key combination works when connected via USB to a PC. All other combinations (Vol+ , Power and Vol+/-) have no effect. Doesn't matter if connected to PC or not.
I can only get into fastboot, however I can't flash images (remote command not allowed), seems to be because of FRP lock.
The device is recognized (fastboot devices) and HiSuite sees it too. Drivers are OK IMHO.
Simply locking it again is not possible, the fastboot lock/unlock options don't work and when booted OEM unlock is greyed out in the options.
dload method is not available, because I can't get into erecovery since the key combination doesn't work.
I also tried factory reset, but:
doing it in the options doesn't work - it reboots and is then stuck in booting. After charging it everything is still there, so no reset at all.
doing it with *#*# 2846579#*#* doesn't work - says can't do it because I have a google account. Removed the device from my account, message remains.
erecovery is not available, can't get in the menue
Any help is greatly appreciated, I would be very happy to just restore it to default settings.
Cheers
Did you removed your screen lock password before unlocking bootloader?
yes, i did. At the moment I don't have a screen lock pw set. Should I set one?
Maybe you need to use dc unlocker
hm, not sure. I got the unlock code from Huwai and it worked. I read up on dc unlocker, how do you think it could help?

Look into DC unlocked Phoenix. It can write to the phone in fastboot mode if the bootloader and frp is locked. I used it and it worked... Cost 20 dollars not better than buying a new phone
Thanks, will try it in the next days and post my results.

How to flash a corrupted Google Nexus?

Dear friends,
I have LG Google Nexus 5 (Hammerhead D821(H) 32GB) model. Some days ago I tried to install Ubuntu Touch OS through UBports Software in my nexus 5 phone. But I forgot to enable USB Debugging first. So when I started the flash process and try to unlock bootloader, one time it show lock state unlocked. But In reality it was not unlocked. Because of this reason Ubuntu Touch OS installation is not completed and it corrupted my phone. Now I am unable to boot in android also. I also tried to re-flash my phone with Google Factory image but it was not completed because of my bootloader is locked. I don't know how i can unlock bootloader now. I used Wipe Data & Factory Reset option in Recovery Mode but it is also vain. Please help me how can I correct my phone.
Assuming you have adb/fastboot drivers correctly installed, you have to reboot to bootloader by pressing volume down + power and keeping them pressed until you see the bootloader screen. Then connect your phone to the PC and issue the following command from a command prompt:
fastboot oem unlock
Keep in mind that unlocking the bootloader will erase all your data, just like a factory reset, so backup everything first!

Dear Sir,
I tried to unlock bootloader with fastboot oem unlock command many times. When I used this command one time it shows unlocked but when I restarted bootloader it again shows locked.
Eh, this is not good. In my experience, this happens when the eMMC has gone bad, either faulty or write protected for some reason. I have investigated the issue and I have not found a solution yet... Even desoldering it and soldering it to a uSD custom PCB does not allow me to write to it... I am afraid you are stuck with a secretly bricked phone...
I don't know if you already tried all possible,just take a look at this thread.
https://forum.xda-developers.com/go...nexus-5-doesnt-boot-access-adb-t2521691/page3
Or even look at this,LG Flashtool.You don't need unlocked bootloader to flash.

The thread is quite old,but needed links are working correctly,i've just checked.
