Unlocking Agreement​
Thank you for your support for Huawei Device’s products. Huawei Device has granted bootloader unlocking permission for its latest mobile phones’ and tablets’ official firmware. Unlocking the bootloader enables you to burn third-party firmware to your device.
However, unlocking the bootloader carries the following risks:
1.Huawei has optimized its products’ hardware and software, but after you unlock the bootloader, Huawei cannot guarantee the best product performance or the normal operation of all functions.
2.Most third-party firmware has not been adequately tested and has poor compatibility with Huawei devices, which will affect your device’s stability or even cause damage to your device’s hardware. For example, the power consumption may become so excessive that your device’s standby time and battery life are reduced, or the RF performance of your device may degrade, which will lead to network search failure or poor call quality. Even worse, your device may fail to start and cannot be repaired. In other words, your device may no longer be usable.
3.The third-party firmware may be vulnerable to malicious software attacks, as a result of which your device’s security cannot be assured. For example, Your personal data such as contacts, messages, and locations may be disclosed. Malicious software may control your device to send messages to subscribe to paid services or make calls in the background, incurring charges secretly. Malicious software may even monitor your device.
4.Some functions will no longer work after you unlock the bootloader. For example, the Digital Right Management (DRM) security password and digital contents you have purchased cannot be used any more. Software upgrade using Firmware Over-The-Air (FOTA) or a microSD card may fail or your device may not function properly after the upgrade.
Unlocking the bootloader will cause unexpected negative impacts on your device, including but are not limited to those listed above. You are at your own risk if the device malfunctions and cannot be recovered. For software and hardware failures, Huawei repair centers can provide and charge for maintenance services.
[ Warnings and precautions ]
1. As determined by your service provider, custom devices may not support bootloader unlocking. If so, contact your service provider to unlock your device’s bootloader.
2.Unlocking the bootloader restores your device to its factory settings and all of your personal data will be erased. Back up your data before unlocking the bootloader.
Before you unlock the bootloader, ensure that you are fully aware of all the risks and that you master the required skills.

[Q]HTC Toush diamond2 Locked

Hi guys
I have installed the free antitheft mobile software of F secure at my windows mobile phone {HTC Touch Diamond2] and, of course, I have chosen the number key for entering the software and my mobile and the sec ret code [letters and numbers] to lock it from distance.
Since then, many times when I was restarting my phone I didn’t had any problem to unlock the software using the number code, and then, with the same number code, to unlock my phone so that I can use it.
Unfortunately, yesterday after that I installed another software [swype] and I had to restart my phone, when I entered the same number code I received the answer that the code was incorrect. I tried many times without result –some time I got the message to use my secret code [letters and numbers] which lock remotely my phone but this is not possible because to enter the F secure software I can use only numbers. Finally now, any effort to enter the number code is without result and I don’t get even the message that my code is not the correct one.
I was informed that the only solution is to hard reset my phone-solution that I would like to avoid for not losing my sms, contacts, softwares installed etc. So I would be very grateful if you could help me
Thanx in advance

Unbranding vs. Unlocking vs. Rooting

I don't where to put this thread specifically but I know there is some confusion in the HD7 forums. So I'm here to explain the difference between Unbranding, Unlocking, Rooting.
Unlocking:
Unlocking your device simply allows you to use it with any other GSM carrier in the world. It is a good way for you to not incur roaming charges since you can travel out of the country(or inside for that matter) and pick up a prepaid SIM card and use it. It does not damage your phone, disable any features or functionality and does not void the warranty. Unlocking your phone can also increase its value, because the phone can be transferred to a non-CDMA based company (CDMA is, in basic terms, phones that have SIM card built-in, but don't rip apart your phone, there is no SIM card; Sprint is an example of a CDMA based company). There are some carriers, who allow you to unlock your phone, for example, T-Mobile will give out unlocking codes for some phones, if you tell them your travelling outside of the country. This is because this specific carrier does not have an international call plan.
Unbranding:
Unbranding, or debranding as it is some times referred to, is where you remove the carrier branding from your device. This will void your warranty since you are essentially removing all carrier affiliation, besides the logo physically printed on your phone, from your device. It is possible for you to "rebrand" your device with your carrier again, although there is no point to unbranding if you're going to do this. One thing unbranding will do is that it will remove the carrier splash screen that is displayed when your phone is booting. It will also revert your device back to the factory defaults, so back-up your hone if you plan to. The process of unbranding your device is not illegal, although for a small number of devices(like Blackberries) the software is!
Rooting[?]:
The reason I put a question mark in brakets is because for Windows Phone, rooting isnt the correct term. Jailbreaking was the first instance of this type of software modification, and freed iPhone users of the incredibly limiting way the iPhone was set-up. Androids were later 'jailbroken'; however, due to the fact the OS is Linux based, they called it rooting due to the way the files were set up and named{I don't know the full reason, go google it}. Anyways, rooting{which is what I'll call it in this thread} is when a device is totally released from all restraints set by the manufacturer. In the case of the iPhone and Android phones, it allowed to install 3rd party application(applications that weren't allowed to be in their respective marketplaces), change the appareance and layout of the phone, and even change the splash screen(what's seen when booting the phone; i.e. for the HD7 its the T-Mobile and Windows Phone logo ). Usually this process voids the warranty, however, in some cases like the iPhone, reseting the phone through official provided software will revert back.
I hope this helped
great info. just wanna say thanks.
: )
Someone needs to come up with a better word for "rooting." I hate the term jailbreak but it looks like we might be getting stuck with it. Maybe if we made the difference clear by calling one "SIM unlocking" and the other just "unlocking."
Call it Sideloading
that'd do for me
so using chevron will void my warranty is what your sayin?

Free LG G4 (H811) SIM Unlock

There are other threads about this but rather than pollute them with my post I figured I'd create a new thread to share my experience. READ THE WHOLE THREAD BEFORE ATTEMPTING THIS. I AM NOT RESPONSIBLE IF YOU SCREW UP YOUR PHONE. Feel free to comment and I will make adjustments to the op.
Pre-requisites
- LG G4 T-Mobile Variant (H811).
- The Phone must be paid in full.
- The account the phone is/was attached to needs to be in good standing.
- Proof of your purchase of the phone (eBay or paypal receipt)
- The phone must not be reported lost, or stolen.
- Try the T-Mobile Device Unlock and select permanent unlock (if it works skip to the section on retaining SIM Unlock)
- Persistence, patience and politeness.
History
I purchased a used LG G4 (H811) on eBay, then called T-Mobile to request the device unlock. I was told by two Customer Service representatives and two supervisors the same thing:
- I either had to get a T-Mobile account and register the device on their network for 40 days and request the device unlock.
- Or the original owner had to request the unlock.
T-Mobile would not budge, but you can make them give it to you. The CTIA Consumer Code for Wireless Service (http://www.ctia.org/policy-initiatives/voluntary-guidelines/consumer-code-for-wireless-service) is a Voluntary document drafted by the FCC and administered by CTIA that T-Mobile is a signer on. In section 12 it states that wireless providers will unlock eligible phones for customers, former customers and individual owners. That third category is the one that most of us fall into. Principle 2 of that section says that for post paid phones the provider will unlock them upon request for phones from accounts in good standing that have been paid off again for customers, former customers and individual owners. CAVEAT: The Code does allow them to charge you a "reasonable fee", but I was never asked to pay a fee.
Penalty for T-Mobile not complying is revocation of their status of meeting this code and they cannot display the seal which means other providers will harp on that and T-Mobile doesn't want that. After sharing this information with the supervisor they told me that I could write a letter to their legal department which I did not want to do.
Getting the SIM unlock code
1- Contact T-Mobile to request the device be unlocked. Unless they change their policy they will likely tell you the same thing they told me.
2- Go to FCC.gov and filed a complaint online stating that you are an individual owner of an eligible phone (T-Mobile never disputed that) and that T-Mobile was refusing to unlock it and therefore in violation of the CTIA code.
3- Go to CTIA.org and use the contact us link to send them a very similar email.
4- Finally go to bbb.org and filed a complaint online against T-Mobile USA (Make sure that you select the head office in Washington State).
In all three I provided my IMEI number for reference (#*06#) and THE SAME DAY I got an email from the Office of the President of T-Mobile requesting contact information to verify eligibility of the phone. I responded back and answered their questions. They needed the IMEI, make, model and receipt showing purchase. She then sent me an email telling me that she removed the block on their server from the app working and allowing a permanent unlock.
SIM Unlock procedure
1- If you are already running any flavor of the stock firmware that still has the T-Mobile unlock app then skip to step 6. If you are on a custom ROM reboot into TWRP and do a complete backup of everything EXCEPT your efs partition. If you later restore your efs partition after unlocking the phone it becomes locked again.
2- In TWRP wipe the device with the default settings.
3- Install a stock flavor ROM that still has the T-Mobile Unlock App.
4- (Optional) Install SuperSU to keep root.
5- (Optional) For good measure flash TWRP recovery in case the ROM you installed replaced the recovery.
6- Boot the T-Mobile Stock ROM and run the T-Mobile Unlock App. Request a permanent unlock and it should successfully unlock the phone.
7- Reboot and test with a non-T-mobile sim.
If you are satisfied with running the stock T-Mobile firmware then you're done. If you, like me want to run a custom ROM, then follow below. The steps below assume you have a custom recovery and unlocked bootloader already, but if not you can look at the threads on this forum on how to unlock your bootloader permanently, root, install custom recovery and install a custom ROM.
1- Turn off the phone.
2- Hold the volume down + power button.
3- When you see the LG logo release the power button for 1 second and then hold it again.
4- You will get a white screen asking if you want to factory reset the device. Select Yes, then Yes again and it will boot you into TWRP.
5- Back up your device (especially the EFS partition), but you need all of it. Use the file manager to move that backup to your external SD card.
6- Perform a standard wipe in TWRP.
7- Restore your backup of your custom firmware but DO NOT restore the efs partition or your device will again be SIM locked.
8- Restart.

Can you explain EXACTLY how to preserve the EFS partition? I back it up and restore it to custom ROMS I install?

In TWRP:
1- Backup
Tap Backup
Tap the box next to EFS
Tap all the other boxes
Tap Select Storage
Tap your external SD card (if you don't have one just make sure you copy the backup to your computer for safe keeping after the backup completes).
Tap OK
Swipe to backup
2- Wipe
Tap Wipe
Swipe to wipe (Default options will not erase your EFS partition)
If you found that you somehow wiped your EFS partition, then restore your unlocked backup and make sure to restore everything. You could try just restoring the EFS but I don't know if it will work.

Hi, I have a generic question.
I am using T-Mobile phone and I was not eligible for the T-Mobile Unlock App, so I decided to use unlock services online. The one I used was unlockbase they have a software that unlocks the phone on-the-go using their software and it requires internet connection. I got my phone unlocked and international SIM working. The question is that if I backup my EFS and MODEM now using TWRP and later restore it will it break the UNLOCK?.
Because the unlock they do is of course by altering the EFS and stuff like that and in that case backing up EFS and MODEM is a safe way to UNLOCK my phone again in future if it somehow gets LOCK again, right?

My Experience with T-Mobile
Complaints posted today to fcc.gov, ctia.org, and bbb.org:
"I purchased a phone through a local sale via craigslist.org, after verifying that the phone's IMEI is clean and that all obligations have been paid in full. I purchased the phone because I travel frequently and have upcoming European travel and want a GSM phone capable of multiple networks. Within hours of the purchase I called T-Mobile support to get the phone unlocked. After two hours on the phone they continued to refuse, stating that they would not unlock it because I don't have an account with them. T-Mobile does not dispute that the IMEI is "clean" and that there are no outstanding obligations. They seem to want to get the a minimum of two months of service and payments before they will unlock the phone. I don't want their service. I just want my fully eligible phone unlocked!
Thanks for any help you can provide.
IMEI: 000000000000000
<contact info as appropriate>"
Edit to add result several days later
I had a call from T-Mobile today. Apparently one of the three agencies that I'd sent the email to forwarded it to T-Mobile. The fellow from T-Mobile continued to flatly refuse to unlock the phone.
I explained to him that it was like buying a used car, taking it to a Chevron station, and being told that it could only be filled with Shell because some past owner had a contract, long ago completed, with Shell to provide gas.
The take-away here is that one should NEVER EVER buy a T-Mobile phone that is locked unless one intends to use it solely on the T-Mobile network.
I'd love to take this to court but the legal costs are prohibitive.

6- Boot the T-Mobile Stock ROM and run the T-Mobile Unlock App. Request a permanent unlock and it should successfully unlock the phone.
7- Reboot and test with a non-T-mobile sim.
If you are satisfied with running the stock T-Mobile firmware then you're done. If you, like me want to run a custom ROM, then follow below. The steps below assume you have a custom recovery and unlocked bootloader already, but if not you can look at the threads on this forum on how to unlock your bootloader permanently, root, install custom recovery and install a custom ROM.
1- Turn off the phone.
2- Hold the volume down + power button.
3- When you see the LG logo release the power button for 1 second and then hold it again.
4- You will get a white screen asking if you want to factory reset the device. Select Yes, then Yes again and it will boot you into TWRP.
5- Back up your device (especially the EFS partition), but you need all of it. Use the file manager to move that backup to your external SD card.
6- Perform a standard wipe in TWRP.
7- Restore your backup of your custom firmware but DO NOT restore the efs partition or your device will again be SIM locked.
8- Restart.

Thanks -- this works, fast and free. Note that the FCC and CTIA complaints are basically unnecessary (even if gratifying). The key is the BBB complaint to the Washington state T-mobile headquarters. The office of the president team member called me back within a day, saying he was specifically responding to the BBB complaint. I emailed him my ebay receipt and gave him the IMEI right during the phone call, and he had me permanently unlocked within 5 minutes with the device unlock app, no charge. They just want to see that you paid for the phone in full. I'm running android 6 v20p on an LG-H811 rooted with Imperium kernel 4.8. I happily closed the BBB complaint saying I was satisfied. If only their front line reps would do this, they could save us all a lot of hassle! Anyway YMMV, best of luck. This beats paying the $30+ for unlocking.

Yes… the bbb complaint will be what gets the ball rolling on your phone, but if the ctia and fcc get enough of these complaints they will put pressure on TMobile to change their policy of not being in compliance to an agreement they made.

unlock will even works if you restore your back up efs partition only from your stock rom to the custom rom Im on turbo rom latest version and it works and i only restored the stock efs partition where i used the app to unlock my lg g4 i back up first in twrp. unlock worked on crickiet sim for me i borrow from my friend to test it.
This works for me ! Thank you so much.
I followed your steps, and it did work. I bought this on eBay like you did. Then I found that this phone isn't unlocked. I asked the seller to make the phone call and the seller already changed his carrier. So I began to search for the solutions and saw yours.
I unlocked the boot loader and rooted the phone, flashed custom rom the moment I got the phone. So as you wrote, I flashed the phone back to stock rom, tried the unlock device app , it said the phone is not eligible for unlock. After calling t-mobile service, I filed complaint like you did, t-mobile contacted me a day after, and asked me my IMEI number , my eBay receipt, then helped me unlock the phone today. It took me like a week, t-mobile agent is slow but it's OK. I'm now using AT&T and it's working on 4G/3G.
i have trouble to fel the complaint im not good at englis i couldnt find Washington State hedwuarter any helpplease ?
Network Locked
Hi guys,
My Phone network is locked, after updating to Marshmellow 6.0 Software version 20r.
it was working fine on lollipop.
phone is clean from T-mobile.
I paid online to unlock the phone, and after 2 days they email me that your phone is unlocked.
But my Unlocked Device app is giving me this error "failure in processing the request. please reboot device and try again Tmobile app" i tried every possible way, reboot the device, uninstalled the apps, factory reset the device but still same error.
any help!!!
I'd just like to say thanks, the guide worked for me. T-mobile didn't like the BBB complaint and it took back and forth about 3 times before they gave in. They kept trying to close the complaint, I kept it open and asked that all i wanted was the IMEI to be whitelisted and finally they gave in. It took forever though, I don't remember maybe a month but I wasn't able to get through on the phone and they didn't respond to my email reply for a long time.
Too bad though because right now the phone doesn't start at all. So it will either get sold on ebay or if I'm super lucky I will get something out of LG due to the big lawsuit they have right now. Lg Should let us trade in the G4 or V10 for a G6 and pay just $200, I think that would be fair!

There are other threads about this but rather than pollute them with my post I figured I'd create a new thread to share my experience. READ THE WHOLE THREAD BEFORE ATTEMPTING THIS. I AM NOT RESPONSIBLE IF YOU SCREW UP YOUR PHONE. Feel free to comment and I will make adjustments to the op.
Pre-requisites
- LG G4 T-Mobile Variant (H811).
- The Phone must be paid in full.
- The account the phone is/was attached to needs to be in good standing.
- Proof of your purchase of the phone (eBay or paypal receipt)
- The phone must not be reported lost, or stolen.
- Try the T-Mobile Device Unlock and select permanent unlock (if it works skip to the section on retaining SIM Unlock)
- Persistence, patience and politeness.
History
I purchased a used LG G4 (H811) on eBay, then called T-Mobile to request the device unlock. I was told by two Customer Service representatives and two supervisors the same thing:
- I either had to get a T-Mobile account and register the device on their network for 40 days and request the device unlock.
- Or the original owner had to request the unlock.
T-Mobile would not budge, but you can make them give it to you. The CTIA Consumer Code for Wireless Service (http://www.ctia.org/policy-initiatives/voluntary-guidelines/consumer-code-for-wireless-service) is a Voluntary document drafted by the FCC and administered by CTIA that T-Mobile is a signer on. In section 12 it states that wireless providers will unlock eligible phones for customers, former customers and individual owners. That third category is the one that most of us fall into. Principle 2 of that section says that for post paid phones the provider will unlock them upon request for phones from accounts in good standing that have been paid off again for customers, former customers and individual owners. CAVEAT: The Code does allow them to charge you a "reasonable fee", but I was never asked to pay a fee.
Penalty for T-Mobile not complying is revocation of their status of meeting this code and they cannot display the seal which means other providers will harp on that and T-Mobile doesn't want that. After sharing this information with the supervisor they told me that I could write a letter to their legal department which I did not want to do.
Getting the SIM unlock code
1- Contact T-Mobile to request the device be unlocked. Unless they change their policy they will likely tell you the same thing they told me.
2- Go to FCC.gov and filed a complaint online stating that you are an individual owner of an eligible phone (T-Mobile never disputed that) and that T-Mobile was refusing to unlock it and therefore in violation of the CTIA code.
3- Go to CTIA.org and use the contact us link to send them a very similar email.
4- Finally go to bbb.org and filed a complaint online against T-Mobile USA (Make sure that you select the head office in Washington State).
In all three I provided my IMEI number for reference (#*06#) and THE SAME DAY I got an email from the Office of the President of T-Mobile requesting contact information to verify eligibility of the phone. I responded back and answered their questions. They needed the IMEI, make, model and receipt showing purchase. She then sent me an email telling me that she removed the block on their server from the app working and allowing a permanent unlock.
SIM Unlock procedure
1- If you are already running any flavor of the stock firmware that still has the T-Mobile unlock app then skip to step 6. If you are on a custom ROM reboot into TWRP and do a complete backup of everything EXCEPT your efs partition. If you later restore your efs partition after unlocking the phone it becomes locked again.
2- In TWRP wipe the device with the default settings.
3- Install a stock flavor ROM that still has the T-Mobile Unlock App.
4- (Optional) Install SuperSU to keep root.
5- (Optional) For good measure flash TWRP recovery in case the ROM you installed replaced the recovery.
6- Boot the T-Mobile Stock ROM and run the T-Mobile Unlock App. Request a permanent unlock and it should successfully unlock the phone.
7- Reboot and test with a non-T-mobile sim.
If you are satisfied with running the stock T-Mobile firmware then you're done. If you, like me want to run a custom ROM, then follow below. The steps below assume you have a custom recovery and unlocked bootloader already, but if not you can look at the threads on this forum on how to unlock your bootloader permanently, root, install custom recovery and install a custom ROM.

I got mine unlocked in 5 days. I heard back from T-Mobile President's office and though they appeared to be reluctant on doing it, they ended up doing it. My device was paid in full by previous owner tho. I ended up buying it as the seller has it listed as unlocked while he didn't understand what unlocked means. lol.
Thanks for this useful post!

I took a chance on this about 5 days ago (basically last Monday, May 29th) and filled out the BBB complaint - for the record I did not contact T-Mobile or do the other complaints, I went straight to the BBB site and just did it through them. About 3 days ago I got an email and a phone call (didn't answer it) from someone in the "Executive Response Team" saying they'd like more info so I fired off another email with basically the same info presented in the BBB complaint, the fact that I bought the phone from a third party, that I was not the original owner, that it had no attachments to T-Mobile anymore (was paid off fully in their system and no longer tied to anything related to them), and because I would be classified as an individual owner per the CTIA document they had no reason to not honor my request.
Got another email and phone call (and I still didn't answer it) yesterday afternoon (Friday June 2nd) saying the device was now unblocked on their servers and that the permanent unlock should go through without any issues by using the Device Unlock app.
Well...
Made about 10 attempts so far and still no go, sent off another email within 30 minutes of him contacting me to say it was unblocked (which was about 1PM Pacific time) and he didn't get back to me before leaving the office so of course now I'll probably be waiting till sometime on Monday (June 5th) to hear anything more but I'll make more attempts as the weekend passes. Could actually be unblocked and it's just taking time for the confirmation to propagate through their system, who knows.
It'll get unblocked at some point and permanently unlocked. The temporary unlock works fine, of course, and I am running the pure stock 20v and I don't even have the bootloader unlocked presently so, the issue lies on T-Mobile's side of things now and they'll have to fix it or I'll just keep sending 'em emails.
YMMV, of course, but that's my current situation.
LG G4 H811 T-Mobile Unlock
rektbloodcells said:
Hi, I have a generic question.
I am using T-Mobile phone and I was not eligible for the T-Mobile Unlock App, so I decided to use unlock services online. The one I used was unlockbase they have a software that unlocks the phone on-the-go using their software and it requires internet connection. I got my phone unlocked and international SIM working. The question is that if I backup my EFS and MODEM now using TWRP and later restore it will it break the UNLOCK?.
Because the unlock they do is of course by altering the EFS and stuff like that and in that case backing up EFS and MODEM is a safe way to UNLOCK my phone again in future if it somehow gets LOCK again, right?

Hello Friend. I have same problem Can't unlock my phone by T-Mobile Unlock app. I saw unlockbase.com is web page and they have phone unlock service. After some searching i found that in the unlockable device list they do not have LG G4 H811. How you was able to unlock your phone with their software? Are you sure they can unlock h811? How much it costs?

N950f-ds [galaxy note 8 exynos] - rmm state lock

Hello,
I negotiated a Galaxy Note 8 (SM-N950F/DS) through a site of collective purchases in Brazil, with invoice and all the accessories.
I did all the tests in the device and I decided to buy it, because it seemed reliable.
The device already had the factory settings, but with Android 7.1.1.
I activated automatic update in order to upgrade the android to 8.0.
I received the update and installed it. When restarting the phone, I started the settings normally, I was able to configure the Samsung Account, but when I was starting the configuration of the Google account my phone blocked.
After trying several unlock passwords, I made contact with SAMSUNG which instructed me to send the device for local service.
When I arrived at the service it was verified that my device had "transport block" and who is responsible for unlocking the device is the store in which the device was purchased.
I went to the store that was described in the purchase invoice and there informed me that the store does not perform any kind of unlock or block, so I could not solve the problem.
After several discussions with Samsung and the store, it was verified that my invoice was exchanged and that it was possibly not true.
It was from there that I realized that I was deceived by the seller of the device, because when I try to contact him, my calls do not complete and he blocked me in the social networks.
The only information I have about him is his name and the phone number that should have already been discarded.
Anyway, I realized that I would have to try on my own. Because of this, I am doing this post. I apologize for the long text above before passing the technical information, I had to explain what happened, because I do not want to pass as a thief.
After doing several research I found that the lock was being triggered by RLC.apk which is located at "/system/priv-app/Rlc/Rlc.apk" in stock firmwares.
I found an instruction that guided to freeze the performance of this app with application Ice box v3.1.9.1.
I tried the instruction, but it did not work on devices with Binary 4 (which is my case). The device continues to locked.
I talked to some technicians who told me that this is a block known as SEDA_LOG or DNP 0001. There are some companies that unlock remotely, but it does not have support for Binary 4.
With rom COMBINATION I can use some applications installed by adb, even my data network works perfectly.
The IMEI is normal, unlocked, and is out of the blacklist.
Other information is that the RMM State is Lock, FRP ON, OEM LOCK ON.
Also, when the lock screen appears a few times the message "Silent Log is not allowed for commercial version, please get the EM token".
Through the Samsung Account I can make the phone ring and even locate it, but it does not unlock.
Some failed attempts:
- flash a rom from another region (the device region is ZTO, I tried O2U)
- wait 7 days for the RMM State to disappear (not disappeared, continued locked)
- freezing the RLC app
- enter several PINs to try to unlock.
- login with my samsung account on rmm.samsung.com to try to unlock rmm, but I can not access.
If anyone can help me, or can guide me in what to do, I am very grateful.
Well, if you got scammed by some nasty person, strictly talking, the device in your hands was illegaly traded, as such, here in XDA no solution will be given or support offered, sorry, these cases appear often, and the moderators usually close the threads

unlock bootloader

does anyone know how to unlock bootloader on huawei phone? i know they stop doing that back in 2018. just wondering if there's still a way.
Unfortunately, Huawei stopped giving bootloader unlock codes on 5/25/2018
Without said code, it is not possible to unlock the bootloader, unfortunately.
This is the reason Huawei gave for the change:
In order to deliver the best user experience and prevent users from experiencing possible issues that could arise from ROM flashing, including system failure, stuttering, worsened battery performance, and risk of data being compromised, Huawei will cease providing bootloader unlock codes for devices launched after May 25, 2018. For devices launched prior to the aforementioned date, the termination of the bootloader code application service will come into effect 60 days after today’s announcement. Moving forward, Huawei remains committed to providing quality services and experiences to its customers. Thank you for your continued support.​
