Question How to return to previous version - OnePlus 10 Pro

I have OnePlus 10 pro NE2210 with NE2215_11_A.17 software version. If I want to go to previous version like NE2215_11_A.16. what should I do, should I unlock bootloader or there is normal process. If I have to unlock bootloader then how to unlock it?

You can use fastboot enhance to roll back..

Are there currently any ways to unlock the Mate 10 (/Pro)'s bootloader?

After Huawei killed their bootloader unlock website, users have been left unable to unlock their bootloaders. Is there something like dc-unlocker for the Mate 10 (Pro)?

Yes dc-unlocker
As far as I know there's only one for the Lite, it didn't detect my phone
DC-Unlocker not supported the following devices:
WARNING:
Huawei P20 EML-xxx all versions not supported
Huawei P20 Pro CLT-xxx all versions not supported
Huawei Mate 10 ALP-xxx upgraded to Android 8x not supported
Huawei Mate 10 Pro BLA-xxx upgraded to Android 8x not supported
Huawei P10 VTR-xxx upgraded to Android 8x not supported

Huawei Mate 9 MHA-xxx upgraded to Android 8x not supported
DC-unlocker works if you're on BLA-L29C432B142 or lower. They did something in B145 which fixed dc-unlockers unlock code generation and the backdoor they use with DC-Phoenix. And you can't use FH to downgrade either (Not tested on B145 but on B148-SP1).
I'm not sure what builds are on other custs, but this is the Night Shot update on C432.
F*ck, my phone was 142 and I have updated in 145 just out of the Box...
Damn.
Dc-unlocker Give it a crack might still work, you just need to make sure you put the phone into management mode so it can read it phone. Just unlocked mine last night. Running magisk v16 working decrypted twrp and emui 8.0

The question is from 148 is this possible to Downgrade with Funky Huawei to lower, 142 for example and Root with DC unlocker ?

No it is not, at least one user couldn't (I know it's not much, but it's a friend of @Pretoriano80). I think someone in the Funky thread tried too.
It finds update and that but stays on 0% forever. He was trying to downgrade to both b145 and b142.

I have mate 10 pro running 8.0.0.141(c636) and I just tried dc it didnt work just got unknown error 375 everytime it tried to read it.
Has anyone tried BLA-A09 8.0.0.119(C567) I cant get dc unlocker to even recognize my phone.
Used DC Locker today on BLA-A09 8.0.0.111 fresh out of the box.

The one issue I ran into was fastboot oem unlock wouldn't work initially. I went into developers options to find the oem unlocking feature greyed out. To fix this turn off automatic updates in developers options. Then put your sim card in and restart your phone. (I was keepoing the sim card out to prevent updates) I was able turn on the OEM unlocking feature after this.

Guys, i just bought mate 10 lite and i have bunch of noob questions. Instead of starting new thread i wanted to ask here.
So my phone on RNE-L21C185B142 version. I read the forums and got my bootloader unlock code from dc-unlocker before its too late. So i am able to unlock my bootloader and root my phone right now.
1- Should i unlock my bootloader? I was using cyanogenmod and lineageos on my previous 2 phones. I like customize my phone thats why i install custom roms.
2-If i unlock my bootloader am i still able to get official updates somehow (like flashing from adb or twrp) without relocking bl?
3-If i install custom rom or root can i go back to stock 8.0.0.142 version so i can unlock my bl again?
Thanks in advance

Locking Bootloader

Hey
So i used FH to rebrand and install the Android 9 Beta version on my P20 Pro.
During this i had to unlock the bootloader. So now, whenever i restart my phone, it warns me about not being safe. Could this also be why Google Pay does not work?
Questions:
How do i lock the bootloader again
Will this factory reset my phone?

313 hour wait time , Are you kidding me ?(Can't unlock bootloader)

I had already unlocked my device way back (July 27) and have permission to unlock on my account . I had locked my devices while flashing a fastboot rom and for the past week i have been trying to unlock bootloader without any luck. And now the tool tells me to wait for 313 hours(13 days).
Why the hell am i supposed to wait to unlock my bootloader again?. I've already waited once and unlocked the bootloader two months back. I do not understand the thought process of the people at xiaomi, like why make me wait again. The unlocking process was time consuming enough and now they had to **** it up even more.
Does anyone know the reason for this issue, and how it can be fixed.
I am really frustrated with how xiaomi is handling this situation

This is normal behaviour from the tool, if you unlock once and then relock all on the same xiaomi account you have to wait, 7 days for 1st unlock. Don't think there is a way round this as its connected to your account
please add your account in MIUI's Settings > Developer options > Mi Unlock status
I'm going through this too, MrCrowley37 have you been successful? I sent an e-mail to xiaomi and they replied that I have to continue using the device, since the device does not boot.
Thank you for contacting Xiaomi Customer Support and sharing the snapshot. I am Saloni and Understand that you are facing issues while unlocking the bootloader.
I would like to inform you to wait for some time and then try to unlock the bootloader as it is a server process it may take some time. Kindly use your device as it has not been used for a particular time through which it can unlock the bootloader.
For any further query, feel free to write us back!
Best regards

I saw your message in another post: "I bricked my k20 so I flashed a fastboot ROM, but selected the flash and lock option by mistake. The fastboot ROM was 10.3.3 and the unlock didn't work. I got the same error you did. I even updated ... "I did exactly the same, did you get it? As you did, should I just wait?

Guide: MIUI Stock Dialer And SMS app for Global RN8/ RN8 pro

Redmi Note 8 Global wow what a phone and what a pathetic dialer (google) and sms(google) app. I am saying this because I had Redmi note 7 with stock dilaer and sms app. What are you missing with google dialer and sms app
1. no theming
2. no sms seperate notification sound
3. No call recording
4. no blocking rules for incoming sms etc
You can switch to official Indonesia or Indian ROM to have MIUI Stock apps.
1. Download only fastboot version (not recovery )
ROM Redmi Note 8: MIUI 11 + MIUI 10 Global Stable India, Indonesia & China Stable
2. Unlock Bootloader (1 week wait) and flashing
https://c.mi.com/thread-1857937-1-0.html
Note1
If you want to change the ROM from one region to another (China/Indonesia/Global/Russia) installed on your phone then, 1st, Unlock Bootloader and then use Method 2: Fastboot Update to flash your phone. (Detailed Guide "Detailed Guide to Unlock Bootloader and Flash MIUI Stable/Beta ROM")
Note 2
DO NOT RE-Lock the Bootloader if you change from China ROM to Global ROM in China phone. Re-Locking will BRICK your phone. Select only "Clean All" option before flashing.
On Locking Bootloader, you MUST visit: On which ROM and Device you CAN and CAN'T Lock Bootloader!
Just follow instructions its quite easy. I have flashed two redmi note 8 global to redmi note 8 indian for one I kept the bootloader open and for other i relocked the bootloader.
Dont hesitate to ask questions if confused
Thank you man
Is there any hope of Xiaomi adding the stock dialer and sms in next update?

Yeah, I was kinda hoping that they would pay heed to our cries when rolling out MIUI 11, but have been very dismayed. Should have gone for the Redmi Note 7, instead of the 8 if If I had only known about this issue earlier. I am using Drupe and Textra as my dialer and sms app, but it is always better to use stock.
Anyways, I will try to change ROM over the weekend, and post the results.

Well, I'm not 100% sure, but unlocking the bootloader means you have to contact Xiaomi in a online method to get an application to do the procedure. So, they will know you have unlocked anyway.

I understood what you meant.
As I sayed, unlocking bootloader envolves a online procedure, and so maybe Xiaomi will know you have unlocked the bootloader. If they have track of serial/IMEI with unlocked bootloader, you local seller can access this list and discover you have unlocked.
But, I'm SUPPOSING they have... Personally, I won't unlock phone on warranty period. Maybe someone else can tell you if I'm right.

These links you provided have a recovery ROM, wich we can flash through stock recovery. Have you tried to flash these ROMs from phone?
I mean the method of tapping MIUI logo on "About phone" settings 11 times, and then open the new menu at right top corner.

Thanks for the reply. I checked the thread that you shared with me, in the list of roms I see several regions but I am not sure if any corresponds to Indonesia, correct me if I am wrong. I would have liked that the thread had been specific to the Redmi Note 8 Pro, because it is very easy to get a brick.

I understand that it is multilanguage, so if the Global ROM comes with Portuguese, is also should have it.

At this moment I am in the waiting period of 168hrs to get the unlock. Xiaomi understands that you unlocked the bootloader since you made the request? or until the wait for 168 hours ends and you perform the procedure ?
If the waiting period of 168 hrs ends and I decide to let the warranty period pass, when I tried to unlock the bootloader again, would I have to wait again ?, that is, when passing a Long period of time, the hour meter restarts?
If at this moment I am in the waiting period, I get an update via OTA, does this interfere with the waiting period for the bootloader unlock?
Thanks for the patience.

That link is for every MIUI device, correct me if I'm wrong. But you're right, isn't clear if the "IN" on that images are Indian or Indonesian. I can't tell you if exists any differences, also. Sorry.
About the unlock, you are only waiting a "code" to unlock your phone. Your request don't means you already unlocked (by the way, you will be able to unlock after the time period ends). I believa will be no problems with OTA, since the Mi account you used to make the request is still on the phone (don't remove the account or reset your phone while you are waiting the code!).
Can't tell if the period to unlock have a timeline, but I believe it don't have. Once you get the permission, it is binded with your Mi account and that specific device, so probally is permanent.
Once you received the code, you will input it on Mi Unlocker. Once done, you're unlocked, and Xiaomi knows you unlocked
the bootloader. But, as I sayed... I'm not sure, I'm supposing this is the way.
Thanks for the info about languages.

Why do you want to flash the ROM of India ?, Do not mind losing the NFC?
I flashed the ROM of Indonesia in my Redmi Note 8 PRO, it is multilanguage and does not lose NFC. Then lock the bootloader without any problem.
What method to use?
In fastboot run the following command:
fastboot oem lock.
Before closing the bootloader, I recommend that you make a backup, because you will lose everything.

How to Unlock Bootloader Asus Rog Phone 3 (06/27/2023)

I created this topic because I can't find a way to unlock the bootloader of my Asus Rog Phone 3. Regarding whether or not I unlocked it before, I would think not, since it was a high-end phone, when I bought it, it did not cross my mind unlock bootloader, root, install GSI roms, among others.
My Rog Phone 3 had Android 12 installed, I tried to Downgrade to Android 11, Downgrade to Android 10, and then use the Asus Original Unlock tool (using all its versions) without favorable results to unlock bootloader.
I also tried EDL Unbrick, although I don't know if there is any tool to unlock bootloader with EDL, tools, anyway, I open this question to see if there is any way today to unlock the bootloader of my Asus Rog Phone 3 (it has 12GB of RAM, It is optional, just in case.) Someone who can help me or access me, I would be very grateful, excuse my English. My goal is to unlock bootloader to root it and then install GSI roms, especially install GSI roms ..
