LG G4 H815 SEA Stuck on LG Logo Screen

So i decided to unlock my h815sea bootloader, every thing went fine. I was able to flash twrp, flash android 6.0 with root and boot into system. I wanted to install xposed, i downloaded v78-sdk23-arm64.zip. I flash the zip and reboot into system. Now i cant go past lg boot screen. Could someone tell me how i can go into twrp? I am able to go into download mode, but LGUP application shows phone as unknown, can I use lg flashtool to flash android 6.0 kdz? OR am i able to flash android 5.1 kdz since i am able to go into download mode. I backed up everything using twrp and have all the files on my desktop.

nvm. I was able to go into recovery and flash genisys rom for xposed framework. For some reason when i try to flash xposed on a stock mm file, phone goes stuck on lg logo.

When did you unlock your bootloader?

I would love to know the answer to that as well.

I was able to get the unlock key when lg accidentally enabled bootloader unlocking for SEA variant on their website. Didn't it use the unlock key until yesterday. Loving MM, so smooth.

There's a guy (shiboby) that is looking for the unlock.bin files to examine to see if he can figure anything out for them. Doubtful anything will come of it, but you may want to send him yours to see if it would help

rom booting problem

rom booting problem
hello guys i have a xiaomi mi 6. I got it from china and wanted to change to a global rom. I started all the proccess and when I tryied to select the rom i pressed the global stable one and it started downloading and installing the global developer rom. When it finished installing I started the device and when i selected the language the phone started rebooting and didnt stop doing that. then I trying to put an other rom to the phone and it didnt let me because i didnt have usb debugging enabled and i couldnt enable it because the device wasnt able to open further than the lock screen. I tryed unlocking the bootloader but me account wasnt linked with the device any more so it wasnt possible. I somebody help please. I am not able to use my device.

Ah but to change from China to global ROM or the other way requires unlocked boot loader...
Otherwise stuff like this happens.
The boot loader can be relocked again after the process.
Since the boot loader is locked there is less chance to solve the problem as you won't be able to flash twrp or use fastboot to flash firmware to the phone.
Another solution will be needed

That exactly happened to me.
I unbricked my phone with testpoint method.
It's easy procedure but you will have to open up your phone..
I Did it and never opened a phone before, its about open it and link 2 dots with a wire or something, and Then it goes to download mode and allows you to use mi flash and flash mi6. I recommend chinese developer rom (it will allow you to unlock bootloader afterwards)
Watch this russian guy do it, he makes it easy it took hours for me just search "mi6 testpoint" on YouTube

I got it fixed thank you guys

bootloader unlock code different from frp unlock code.
installing other device firmware has chance to replace oeminfo.img partition. Changing this partitin often causes locked frp.
If lucky you can wipe from the erecovery that is loading. maybe even couple times. Then maybe it will boot. Other that that there has been no public mention of any fix.

do your best to fix it using hisuite or other methods if you can. if you have twrp that can help if you have stock recovery and locked frp your only hope might be hisuite and if that fails you will need a paid option like dc-phoenix or funkyhuewei. i only have experience with dc-phoenix, and it did fix my locked frp completely bricked phone, but i read that funky also works well but is nearly 3 times as expensive. (15€ vs 50€)

The displayed build number comes from the data part of the update. (Update_*hw_*.zip)
If you reflash again all three files , might be fixed

If flashing again is the answer to solve problem. Use my guide here.
You are on Oreo now so use the top portion. "Flash update"

I don't want to sound like rude or anything.
But I put it all pretty simple, I thought. Like 4 steps
Download files
Put files on SD card
Install twrp
Install file I shared
If that is over your head, maybe you should not have modify and phone.

You bought second hand phone?
If no then you have nothing to worry about.
And even if you bought second hand just link your mi account to the device and you'll be good to go

No it was just bought to a Chinese store new, and already have my mi account, but in any process (Twrp, root, ROM install) will ever ask me about the bootloader account?

Hey there, so I'm confused. I bought the redmi note 5 pro from Amazon and it said unlocked. I have it on T-Mobile. If it's unlocked that means i don't have to go through the xiomi back? On the box it says global room. It the settings it says I have whyred room. So can I flash a rom already ??

Check fastboot oem device-info
in fastboot. If true , you are unlocked to flash custom ROM, recovery etc....

Question Bootloop to fastboot logo and back in lock state

Hi everybody,
yesterday I tried flashing the stock pocof3 rom back onto my phone, but since it got stuck in a bootloop at the fastboot logo. Showing the poco logo for a milisecond and then straight to fastboot..
(before this I flashed twrp and the arrowOS recovery and images a few time trying, without succes, to install this rom)
Last thing I did was flash via the mi-flash tool and did't see the "clean and lock" selection so it's also in lock state again.
I cant get adb to find the phone although the mi-flashtool is finding it.
anyone any tips?
I tried the vol up power trick, but this didn't help, keeps loading into fastboot

I'm not sure, but you may still be able to flash official ROMs.
But in "Configuration" make sure Erase is disabled

BAD NEWS... your Poco is bricked. You cannot flash ANYTHING using a PC when your bootloader is locked.
(I did same thing on a Mi11 5g last week and ended up selling it on eBay for spare & repairs
I tried sideload flash, miflash, copying update.zip to internal storage via ADB, and many other options - all without success).
- if your POCO is under warranty in your country (i.e. not a chinese import)... contact Xiaomi Support they can re-flash correct ROM
- Ask your local phone repair store... they *might* be able to flash original ROM back by using "Chimera" engineering software.

- Bootloader was re-locked whilst a custom ROM was in the phone.
(MIUI with Locked bootloader will not boot up where ROM is not stock or does not match the region/product code).
You cannot apply for bootoader unlock because you cannot boot up into Android and request the unlock via Developer mode.
You cannot remotely (via PC cable) flash any ROM into a Xiaomi / POCO phone whilst botloader is locked.
You are in a chicken and egg situation.,,, but if you find a way to repair your phone, please let us know how you achieved it.
Good luck!

If the system hasn't booted up yet there is a chance that you will be able to unlock bootloader again. Try it.

That's what I'm thinking too ...
Connect the phone to pc and do the bootloader unlock again via the mi unlock app - you don't need to apply again and stuff as long as you're able to recognise the phone inside app correctly

tried unlocking it via the mi unlock tool (latest) but it says (in chinese) its locked by nr 123***456 by searching the phone - can't unlock
edit:
google lens translates:
X The phone has been locked by the account number 661****647 by searching the phone, Can't unlock
but it's not the nr. of my account..

Is it not even possible to flash Official ROMs?
Isn't there like a system that it checks the signature of the ROM and if it's a signed ROM it allows the flash? Or am I mistaken?

Nope bootload locked = no 'remote' flashes via pc
Apparently there is an 'authenticated user' mode for Xiaomi engineers in MiFlaah and also an EDL Emergency Download Mode which you can trigger by shorting out 2 pins on the motherboard so bypass bootloader lock and flash any ROM
Neither were available options for me

I'm now in the procedure to sent it back under warranty. any idea if this is possible and what the cost would be if not under warranty?
If all fails i'll try the shorting by pins, should be interesting

I think a warranty repair claim is your best bet ... I have never read anywhere that unlocking bootloader invalidates Xiaomi warranty (Unlike Samsung and so many other brands!)
If warranty repair is re refused try a few independent repair shops
Last resort is get the back cover off the phone and short out the EDL pins
Good luck!
Let us know if you manage to get your phone booting up again

I once hardbricked (complete blackscreen, not even Fastboot reachable) a Poco F3.
I requested a replacement from Amazon and that worked.
I said a software update bricked it.
Of course having to do that is really bad, but I was scared of opening the back.
