Hello, my mate gave me G900NVM (firmware G900NVM20n) with not working Google Pay and CTS profile match fail in SafetyNet test. As much as I know it's cause of unlocked bootloader. So I tried to enter fastboot to check oem lock status, but I can't get into it, when I'm typing "adb reboot bootloader" that phone just rebooting. Also I can't get into it through recovery, cause there is literally only dead robot icon. Is there any other way to get there?
If you are talking about G900VM from Verizon, the phone fails CTS matching even without unlocked bootloader. I believe LG engineering took a shortcut and never certified their firmware with Google.

Hi, I understand probably not very many people still use Honor 6 these days but maybe somone might be able to help. I got it second hand with official B380 ROM (Android 4.4.2), tried upgrading to B521 (A5.1.1) which didn't finish and caused bootloop. It's L60-H04 version (EU distribution).
the problem: the phone is soft bricked (stuck in bootloop), I can't get to recovery mode, and the three button method with a full ROM on SD card doesn't work either (upgrade either doesn't start at all or gets stuck before finishing); I can get to fastboot mode but flashing doesn't work either, I get the "remote command not allowed" method both when manually using fastboot and typing all the commands and when using Huawei multitool. I assume this means the bootloader is locked. (Although when I check bootloader status it says unlocked, however I've read this might happen but in reality it could still be locked).
I assume it means both boot and recovery are damaged, so flashing (fastboot, adb) seems to be the only option. Unfortunately, the phone is second hand so I have no documentation, don't know the imei and serial number to request the bootloader unlock code.
So, is there any other way to get the code? Or does anyone have any other suggestion how to unbrick? Any help is appreciated.
SOLVED - solved by using paid tools DC-Phoenix and HCU-client
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.
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
Rescue and smart cannot flash phone ADB side load does not detect device not sure what next method to try
You can try to edl short the device to flash a blank flash file to "rejuvenate" the bootloader. Then use tinyfastboot script to "flash" the exact version of update that was last installed on the device. Search for tinyfastboot script on lolinet. Unzip, Run the .bat file given. Select version. Hit 5 hit enter/return. Watch A LOT of red words go by very slowly. If it's going slow then your device will be flashing even though it says it's not. Patience don't just unplug it real quick or close the bat when you see red right away. As long as the program doesn't stop you got the right update. If frp locked find a guide on hardreset.info or you won't get past checking pin or Google account. It will more than likely trip verity and reboot device. Remove security pin/pattern/password and Factory reset from settings > system > reset. If you want bootloader unlocked again you need the same code from Motorola bootloader unlock email as prior unlocking. (Not sure if you can reapply for it, haven't tried as I had my old number)
Hello beautiful people of the internet!
I am in dire need of some help - today's morning I did the unthinkable and locked myself out of my phone once again, only this time I'm clueless how to fix what I have broken.
So i tried to lock the bootloader with fastboot oem lock and after I did, I got the "No valid operating system could be found" .
So now I'm stuck without any system to boot and flashing locked, and recovery doesn't exist either.
Is there anything I can do to fix it? I feel like I'm running out of ideas at this point.....
Thanks in advance!
The way to recover it is to flash it with an octuplus type box or another similar one. This can be done remotely, something similar happened to me with an LG and a Ukrainian repaired it for 10 or 15 dollars. Ask in the telegram group in case they know someone
I've been struggling to get mine working again, I'm at the point I need to remove an EM shield to pull a specific pin to ground to get to EDL mode...
Did you disable "OEM Unlock" in the Android developers settings? If you didn't, and since it's a Motorola, you can unlock your bootloader again with fastboot oem unlock <UNIQUE_CODE>.
(Side-note, it is a wonder why it's at all possible to lock the bootloader again without making sure "OEM Unlock" is enabled in case something goes horribly wrong and you can't do anything anymore with perfectly working hardware, forcing people to get to EDL mode, mode that is made less and less accessible over time. "OEM Unlock" should never be allowed to be turned off if the bootloader is unlocked.)
Pretty sure your problems are stemming from the use of fastboot oem lock, instead of fastboot flashing lock...
You can relock the bootloader, but only with fastboot flashing lock, as far as i know.
The moral of (my) story is, dont unlock if you want to relock later, the forum is littered with similar cases to this one sadly.
