[Q] Can I Bootloader Unlock this Phone? - LG Optimus L9 P760, P765, P768, P769

Hi all,
Looking to bootloader unlock a P769 to intsall custom ROMS.
Here's the current system info (rooted w/ CWM):
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
It looks like I can use this (kuma82's) method to unlock the bootloader:
http://forum.xda-developers.com/showthread.php?t=2601480
But I'm seeing other threads for people looking for alternate methods to unlock the P769 bootloader:
http://forum.xda-developers.com/showthread.php?t=2557249
http://forum.xda-developers.com/showthread.php?t=2653639
But I can't establish why those people cannot just use Kuma's guide, need to know that his guide will work for this phone.
Any ideas??

I used kuma82's method
The P769 is annoying to unlock but kuma82's method worked for me after I'd unsuccessfully tried various others. The trick seems to be to leave your L9 on with data connected for as long as you can (45 mins is suggested, but I left it for around double that). Make sure you disable any screen lock and turn on "show touches" in developer options before you do anything - the crazy messed up screen drove me insane I also opted to leave the screen on and left the phone charging throughout so that sleep didn't interfere. Good luck!

Can you tell me the date under your battery?

Date under battery
Sure, it's May 2013. I purchased the phone in Nov 2013 reconditioned from Wind Mobile in Canada. I updated to the latest official kdz using offline flash (21D, I think) and had artas182x locked bootloader CWM recovery on there (as I was thinking of flashing kuma82's themed rom for locked b/l). Didn't have any joy with unlock methods listed on XDA and elsewhere, gave up for a few months, then tried kuma82's script and it worked. Hopefully others are finding the same.

[Q] Help needed for unlocked STOCK T-Mobile HTC Amaze

Hey everyone, I've searched thru the forum looking to see if someone had the same issues I did, and the stellar assistance that was given to others with various problems, I'm hoping that I can get the same (haven't seen anyone with my particular issues yet).
As mentioned in the title, I'm using a stock T-Mobile Amaze, unlocked and I'm using it in Barbados. A few weeks ago, a notification popped up on my phone.

Naturally, I was curious to see what this update was, but after ensuring that everything that was required for the update was in place, I see this...
...which I'm sure means there's some error in installing the update. The phone freezes, and I can't get out of this without doing a battery pull a la blackberry. This is issue 1.
Issue 2 is that a lot of my menus have wrong names, e.g. the 1 for Wireless connections says "Turn It On"
and even the options within the menus are wrong, e.g. In the display menu, to set the screen brightness, that option is entitled "Set A PIN code to lock your UIM Card"
Further to these, often when I try to access many of my settings, the whole shebang crashes, and asks me about sending an error report. Til now, nothing has changed in that regard. Any assistance to these problems would be GREATLY appreciated. Thanks in advance.
Your best bet is just to do a master reset on the phone. It should clear up all those issues.
tried it...didn't work (well, the menus still are screwed up, and the settings keep crashing when i try to access some of them, like the Sound menu.)

Have you tried locking your bootloader and flashing the stock firmware?
You already unlocked your bootloader, right?
Just flash a custom rom.
If you REALLY want to flash the 1.43 update then relock your bootloader and flash this: http://goo.gl/KvHzj
Rename it to PH85IMG.zip and store it on the root of your sdcard.
It will update everything.
Then unlock your bootloader again, reroot and you'll be good.

Bootloop? I got in one after Aroma froze, I tried going back into recovery and it only flashed up for a second and then rebooted.
1. Re-lock boot loader, then unlock it again
2.Wipe cache via Fastboot("Fastboot Erase Cache").
3. Flash Recovery again. Reboot into recovery.
4. Sideload a ROM with ADB

It's NFC. It's there to let you know NFC is enabled, to get rid of it, flash an international ROM, or go to settings>more>NFC and uncheck the tick box(Note:This will turn NFC off.)
Faint blue horizontal lines on the screen in direct sunlight. I've seen them they exist, you may want to check if you haven't seen them. IDK what to do about this problem yet.
Faint popping sounds after playing a sound through the speakers. I've heard this too, but I hear a software update may fix it. If you want to hear this yourself listen to a sound, stop it and place the phone near your ears and after about 2-3 seconds you may hear it. (Note: Very very faint sound need to be in a quiet room.)

LG V30 in some sort of bootloop after factory reset.

Device is a pretty much new LG V30 from verizon, running android 8.
I have done pretty much nothing with the device yet. No root, no tinkering, nothing. I accidentally accepted the software update request it showed me today, which I didn't want. I shut the device down but everytime I would turn it on it would start the update progress.
The only other option I had was booting into recovery, so I did that. I was presented with the following options:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
So I went with factory reset. After that the phone won't boot anymore, and all I see is this screen:
What can I do now?
Again: No root. No unlocked bootloader. Nothing. I used LG's "require password on boot" feature though, which I assume is equal to android's full disk encryption. (?)
I talked to LG already since it's under warrenty (got it literally last week) - LG however told me the warrenty is void because there is a small crack on the back of the phone. WTF? Is that even true? I didn't drop the phone. I don't even know where the crack comes from. It's small. Shouldn't the warrenty cover that TOO instead of voiding the warrenty for everything else? Like jesus christ all I want is LG to fix my software why does a crack on the back matter?
From what I see my only option is to access fastboot and re-flash the ROM? The thing is: How do I access fastboot on this phone? Power and Vol- brings me into recovery (stock) everytime. Are there flashable images for the V30?
No one knows what I should try or what I could look into? This doesn't sound like it could be something overly complex to me.
Issue still persists. I had a talk with verzion at their store and they said I'd have to pay a $149 deductible. So what can I do now?
I'm assuming flashing a ROM via fastboot. Two questions:
1) Where can I get the ROM from?
2) How can I access fastboot on this phone? The method suggested everywhere puts me in LG's stock recovery, not in fastboot.

OEM Unlock 7 or 14 days, RMM state...

I read a lot in these forums here about OEM unlock S9+ but until now it did not work for me. Additionally there are lot of confusing information around here...
Can anyone (from OWN experience !) please write how unlock, waiting-time and RMM-states are related?
I bought a new phone from U.K., a variant which actually is only available in the Asian market as far as I know.
Color blue with 256 GByte and dual-SIM.
It has EXYNOS CPU !!! As you can see from my attachments, I have already been waiting 7 days for OEM-unlock with no success. I did not boot into download-mode yet.
I assume Samsung has produced phonse, even with EXYNOS, where the OEM-unlock is impossible...

As far as I know, so far, only the snapdragon variants can not be unlocked using the OEM Unlock feature.
I had a custom ROM for about 5 days, and to be honest I sort of wish I hadn't done anything at all. Unlocking the bootloader breaks things like Google Pay and Device Certification on Google Play. This stops things like Netflix and other services (seemingly only ones that rely on Googles Windvine DRM - although the APKs can be installed manually). The second you load TWRP, Knox is gone forever. It is unrecoverable. This I care less about, although Secure Folder had its uses for duplicating apps.
Yes, its possible for Root to fix most of those, but its an endless cat and mouse chase and often breaks when Google update things (I could not get Google Pay to work at all despite Magisk Hide)
During those 5 days, the OEM Unlock option was unavailable to me. When I decided to go back to full stock condition (minus Knox) I loaded all the correct things in via Odin, and the OEM Unlock option was available, with the slider in the off position.
What I want to know at this point, is does turning it on re-lock the bootloader? Because if it does that would likely solve my issues with Google Pay (its incredibly handy).
To answer your question though, the standard waiting time is usually 7 days, after which it will re-appear.
I now rebooted to download mode to see the RMM state. It is Prenormal...

Probably someone tried to root it and made RMM to change to prenormal. Have you tried checking if RMM/KG is showing prenormal in Download mode?

Can i fix this problem );
Yes, typically the RMM resets after 7 days. There might be a quick fix which I am unsure of, so keep digging on xda.

I just got the Edge Plus (named that here in the US) Same phone as this, and mine is like this too, brand new out of the box like this.
Having the same issue, greyed out OEM unlock button.
Brand new, out of bocx.
Also when I go to the motorola site, it says not eligible to be unlocked, which is bizzare. Its fully unlocked!
My guess is it takes some time for the button to not be grey, according to what I read here.
Still need to try to get the code though from the moto site.
Fairly confident the Oem unlock button will be active in a few days.
Does anyone button greyed out get the Oem unlock code? I can't get that. Fully unlocked device.
ok was able to get the motorola unlock code, about 24 hours after I got the phone. Still, cant get the OEM unlock to toggle. Tried multiple reset options and nothing worked (sim, no sim, wifi, no wifi).
Did a factory reset and it worked!
