No bootloader?

Good morning,
Having bought a phone LG G4 from China I doubt a bit of their ROM (we never know if they added cookies or what ..) So I decide to get started in the installation of a custom ROM. So already I notice that the phone is already rooted (while it was under blister). Well then I have to unlink the bootloader and I must restart in fastboot but nothing done I can not access the bootloader ?? I tried with the command window (adb reboot bootloader) but it restarts on the home screen .. ditto with an app boot manager, I go back every time on the home screen. How come? I do not have a bootloader or what ??
Thank you for clearing me up.
Sorry for my english

not all LG G4 can be bootloader unlocked only some european and tmobile usa one.
if you had root maybe it was on lollipop phone is bootloader locked.. in lollipop only it can be rooted using system.img rooted. and injecting.. but if you update to MM with locked bootloader it cant be done. no root nothing..
also downgrading in somephones to lower android version bricks phones they have antirollback.. not sure it it applies to all g4. mine does it tmobile.. maybe other can be downgrade. see if yours can at lest to have it rooted..

I don't have the fastboot mode, so you think it's normal? Mine is on LP but I can't update to MM (the category update is missing in settings) wich I think is due to the seller chinese, he did some strange things on the phone I think.

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.

Your Device Has Failed Verification And May Not Work Properly

I recently got a 7x from ebay.co.uk. I noticed the opened box states the model is BND-AL10 (Chinese) but in the phone settings it's a BND-L21 (International). S/N and IMEI match.
Out of curiosity I tried Huawei Firmware Finder for Oreo. I used DNS method, picked the top one as seen here (verified): hxxp://pro-teammt.ru/firmware-database/?firmware_model=BND-L21C432&firmware_page=0
It downloaded like 20 patches totalling around 8+GB and then asked to reboot...and failed.
My phone still works but I now get this during boot:
"your device has failed verification and may not work properly.
1) Press power key to continue.
2) Press volume up key up to 3 seconds to enter erecovery to restore your device.
3) your device will stop,start if there is not operation.
I tried Huawei eRecovery: 'Getting package info failed'
What should I do? Noob.

erecovey fails for everybody. dont know why.
the message you see is normal if bootloader is unlocked. You should have had that same message first time you turned it on too.
Attempting to use firmware finder to apply updates , is not possible to unlock bootloader, so it had to have already been that way.

This is known message resulting from of having boooader unlocked. Few people have been trying to make it not show , but no one has made it public if they have been successful at hiding it.
Now you got that phone (used, I assume ).From eBay. Perhaps the previous owner found some way. And attempting to update made his "hack" undo. Don't really know.
You can check if bootloader lock status to be sure if it is unlocked or not.

In FASTBOOT&RESCUE MODE:
PHONE Unlocked
FRP Lock
This phone is sold as brand new boxed. However, like I said it was opened. I wasn't expecting to get a Chinese version that has been flashed. I should have just paid a bit more from Amazon. Though, I'm not fussed as long as I get updates and it's stable.

that status is very bad.
that combination of unlocked bootloader and locked frp is often hard if not impossible to get past.
unless you can access developer options menu and enable "enable oem unlock" menu option.

PHONE Unlocked
FRP Unlocked
I read that "Huawei is no longer offering bootloader unlock code in 60 days." I tried to request a unlock but I get just get
"If you have any questions about the unlock code application, please contact us."
Nothing happens. I contacted them.
Will I ever need that unlock code given that it is already unlocked? Should I return/refund the phone and buy from Amazon UK or am I wasting my time, since I'll likely be requesting a unlock code and possibly be playing with roms in a few years. I keep phones as long as possible and a basic user which is why I have little knowledge with them.

I would try and get a refund (if you bought via PayPal I think you may get some kind of support).
You can get the 7x from UK retailers for as low as £210. But the current Amazon price of £228 is not bad.
Do you browse HotUKDeals? Always check there before buying anything in the UK or from China.

Yes, PayPal. I contacted the seller on the matter. Will see what they say. After using Firmware Finder correctly I updated to 8.0 Oero. The message during boot also went away... I'll certainly check out hotdeals. But if the phone works should I bother?

i think it is a little suspicious on the bootloader getting unlocked like that, but if its working , and you flashed full ota, then maybe give it a try.

"Dear buyer,
Sorry for bring you any inconvenience and disappointment, the reason we have opened the package is because we need to download a multiplied language system to the phone before sent it out, they it can be use normal in this country. And for the model no, that's a normal phenomenon after rooting the phone.
Anyway, is it affect your use? what can us do for you now?"

Since the bootloader is unlocked I won't need to request a unlock code or ever need that code? As I did read Huawei is no longer offering bootloader soon.

Bootloader unlock and relock
deleted, posted on a new thread

Hi. I'm having an issue with this new phone. It's Wowi Ultra SQ766. On start up interface the 'Red State' notice comes up, goes off for 5 seconds and comes back on. The full message states:
'Red State
Your device has failed verification and may not work properly.
Please download boot image with correct signature or disable verified boot.
Your device will reboot in 5 seconds'.
Could you please help me out with a solution or fix for this.
I'd be happy if you would help.
Awaiting your reply.

Stoping this damn RMM State Prenormal

Hi there.
I've been stuck with RMM State Prenormal on my Galaxy A8 2018 for 3 months, waiting for this to be gone. Nothing to do, after 3 months of uptime, it still there.
Many tricks with time and date hasn't worked anymore, but finally I just success to bypass this s***.
What I've done :
_Install stock rom from original carrier (BOG for me, I were on XEF for deleting bloatwares).
_At boot, do NOT put your Google account and Samsung account, only Wi-Fi and that's all.
_When install wizard is finished, do NOT activate Developpers Options. Go directly at time and date, set it 8 days before after desactivate "Auto time and date".
_Go to System Update. Then untick "auto update" and check for update.
_Reboot.
_Go back to actual time and date, check again for update.
_Only NOW, activate Developpers Options and OEM Unlock should be there.
It worked for me after MANY MANY tricks, attempts, and hopeless. This way given me another luck to root my phone and now I'm done and free with it.
Sorry if my english is sometimes bad. Hoping I've helped some users.
Regards !
Edit : I did it on bootloader V3 (U3BRJ4).

I hope it actually works with other a530f
because I have a530w and a530w doesn't have rmm prenormal in bootloader, I can't really test this

Yup, canadian and some versions of samsung smartphone (Verizon or something else if I don't mistake ?) doesn't have any method to unlock their bootloaders because they are locked by default and forever. But I've posted it for those who have international variant (SM-A530F for me).

no, I mean that Canadian variant of a8 is exactly the opposite of what you said, rmm is always unlocked, so oem unlock is always there
and a8 is the only exynos Samsung device in canada so we're lucky we didn't get any snapdragon version or that would be locked forever

Oh, mea culpa. I thought it was like Galaxy S4 who were totally locked (received one from Canada to France, last year, I were disapointed that is not GT I9500 but SGH I337M).
But the result stay the same, this is for unlocked bootloader that can be "locked" by RMM State ^^

once you downloaded it, extract zip file, then there should be 5 files, dont worry about the HOME_CSC, that leaves us with 4 files, put them in the correct position on odin, AP to AP slot, etc

You don't have oem unlock to use Odin.
