cant unlock my bootloader

When my new phone arrived, it had bootloader unlocked, but after my phone was rebooting randomly , i have decided to flash a latest global rom with mi mix flash tool. When i did that, my bootloader got locked again. Whenever im trying to request unlock through official website , i get some crap in chinese "您所在的IP申请次数超标" does anyone had similar problem? and if yes, what did you do.

Not an expert but while waiting for mine to get approved for the first time I read that once it's unlocked you don't have to request it again you can unlock it again anytime. have you tried unlocking it with the tool yet?

A mi me pasa lo mismo. Siempre me aparece este mensaje en la pagina web: 您所在的IP申请次数超标.
Con esa herramienta me dice que el dispositivo no es compatible.

Same here.......
Same here. The message says that your IP is blocked. I've tried getting around it and haven't managed it yet.

Check using fastboot if you are already unlocked,
fastboot oem device-info
From a pc command prompt or terminal if using Linux.

Same problem here! I also made a second attempt after waiting 24hours. I checked with fastboot and it is definitely locked.

I just managed to do it over a friends computer! SMS was first not sent when entering the page. I waited for 10minutes. Pressed the chinese button. No SMS. Clicked again on the chinese button and then received the SMS.
And now they already granted permission.

Yes, I've tried that method it, it still won't allow me to enter the bootloader. I've tried to enter recovery mode as well but i can't either.
It seems very strange. Its like it's locked in some way.
This my model number

is your phone a h811 and not a frrankenphone .. means it says h811 but actual model maybe another . thats reason maybe you cant unlock.

It's definitely a h811, it says it on the back of the phone, underneath the cover.
But I did buy it unlocked so I could use my sim card.
Maybe that is the reason, but I really don't know.?

thers 2 types of unlocked.. sim carrier . means you other sim not tmobile and... bootloader unlocked to flash custtom roms and kernels ect...
just in case you have doubts.
you want to make sure is a h811.. open up phone and take motherboard and read model number on motherboard plaque.

if you bought cause you wanted h811 i would ask for refund.. they are refurbished phones. they edit software.. so now if you going to keep flash h810 stuff... yes it can be rooted. with rooted imaged pushed in a command.

Need EFS backup from V405QA

Hi guys, for developing unlock of Sprint v40, we need EFS backup from unlocked model V405QA (to compare some things between models).
You can do it by QFIL and QPST tools (to eliminate possible bugs)
Turn on Diag mode: In dialer *#546368#*405#, type 000000 in service code, then press SVC menu -> Port Check Test -> Enable.
Manual for QPST: https://forum.xda-developers.com/redmi-note-3/how-to/guide-qpst-tool-backup-imei-nvram-t3455297
Manual for QFIL: Start QFIL. Open Tools -> QCN Backup Restore. Click Browse and save it in cozy place. Press Backup QCN.
After finish you should see: «Done downloading the qcn file: C:\temp\00000000.qcn» and «Finish Backup QCN».
Manual for NV-items_reader_writer: Set port, click checkbox right after 000000, click Connect, Click Read button right after Connect button, click Read in main window.
Dont forget to turn off Diag mode after.
Many thanks! Your help for community will be greatly appreciated.

Hi.. i was wondering if we backup EFS from Sprint unlocked and restore it to Sprint locked will unlock the network for worldwide sim card?
Would it do any harm or changes to Sprint locked v40's IMEI?
I currently owned a Sprint unlocked LG v40.. bought it from Ebay, put in my Indonesian simcard and works perfect.. 3G/HSPA+/LTE great

Probably yes, with crossflashing unlocked firmware it can be big win for locked sprints.
IMEI will not change, we are searching only for items that locking network to sprint.
Im away till 11 march, but if I can contact you and help with backup, it will be great.

if I backup EFS from Sprint unlocked and restore it to Sprint locked, will this method unlock the locked one?

I can get the efs from an unlocked sprint lg v40 can also get the locked one if you need it

So the job is to get both sets of efs locked and not locked then compare and take what makes the phone unlocked and copy that info into the locked efs then write back?

What about nv items? Just like samsungs j727p is unlocked nv items will be easier then doing the whole efs system.

No.
I have crossflashed v40 with QA firmware, but EFS is not changing while flashing firmware. Network lock is located somewhere in EFS.

How did you crossflash?
Also i believe when cross flashing a v30 it doesn't touch the efs system either it just bypasses the lock its still there but because of the new firmware it tricks it into working thats what i was under impressions.

If you have a functional LGUP version and DLL for crossflashing V40, please share, this would be a huge help for many folks here.
I have extracted the DLL from the latest LM-V405EBW KDZ but haven't been able to locate a version of LGUP which will successfully flash the device.

I also have a v40 with the bootloader unlocked (can enable USB debugging in Developer tools), but whenever I try to boot to fastboot mode (either from recovery or adb) it just boots back to normal Android OS.
Were you ever able to figure this out?

I've been on Android for 10 years, originally with the Galaxy S1 and many devices across multiple manufacturers.. The ability to "Enable OEM Unlock" at all has been a key indicator of whether the bootloder was unlocked. This was true for all of my devices, up to my LG v30 that I continue use for my daily driver.
The v40 was the first device that allowed me to enable OEM Unlock without the bootloader being unlocked, which is why I was confused.
Thanks for the reply.

I'm having the AT&T version (LM-V405UA), can I unlock its bootloader? I can't seem to be able to boot into fastboot mode though.. Weird.

Almost every Android I've had allowed me to enable OEM unlock....since for the most part it needs to be ticked on so that you can unlock it...

Right. That was my point as well.
https://en.droidwiki.org/wiki/OEM-Unlock
Enabling OEM Unlock itself does not unlock the bootloader, but you can not unlock the bootloader unless it is unlocked.
This is the first device I've used that allowed me to enable OEM Unlock, but DID NOT allow me to unlock the bootloder. For other devices that had a locked bootloader, the first step of enabling OEM Unlock wasn't even an option, it was either missing altogether, or it was greyed out and unchangeable. That was my confusion.
