help me please! oneplus 3 - OnePlus 3 Questions & Answers

hi guys
I’d got a big problem on my oneplus 3. My device’s oem lock was disable (in developer setting) and my bootloader was in locked status. I cannot use the command: fastboot oem unlock. The command said remote unlock is not allowed. I don’t know how to unlock the bootloader in fastboot. I tried to ubrick my phone but it didn’t work. It said: check md5; cache failed…. and it reset the phone many times. I also couldn’t open recovery mode. Please help me. I really need your help. You are my only hope now. Thank you in advance

Have you tried the unbrick guide? I'd try that out before doing anything else, see if the guide works and then retry unlocking the bootloader.

You didn't follow the Unbrick guide properly.. If you get these MD5, cache, system etc failed that means you didn't use the right drivers provided in the tutorial.. Also you do need to boot windows into driver signature enforcement.

Driver Signature Enforcement should be disabled.

Yes my fault. Make sure you boot windows without Driver Signature Enforcement.. Googling helps a lot

Virtually impossible to unlock bootloader

Guys, I need some help to confirm the only solution I found for my problem, or if I can still try other solutions.
I bought a Mi5s that already came from seller with the global stable rom. I asked the official bootloader unlock to Xiaomi and has received authorization by SMS. But the unlock application stucks at 50% saying that the device being unlocked is different from the one authorized on Mi account. I looked for some solutions like deleting all the devices in the page i.mi.com, leaving only the Mi5s, but I did not have success. Other solution is flash chinese developer rom
Another solution is to flash Chinese developer rom, to confirm unlock of the device on the developer screen and then to use the official tool unlock. But I didn't find any way to flash the developer rom. I've tried using Chinese PC Suite, fastboot mode, MiFlash, and all says that the rom I am trying to flash (Chinese) is different from the rom of the device (global).
The only solution I found is to buy a deep flash cable and flash the developer rom in EDL mode. Or hope to launch the global developer rom for Mi5s, which so far we have no prospect in the short term.
Do you suggest I try some other solution? Thanks in advance.
Try logging into mi cloud with your mi5s using the same account you used to asked the request to unlock.

Already had done it, no success
From http://en.miui.com/thread-482266-1-1.html
Under settings/additional settings/developer options, click Mi unlock status. Click add account and device. Your device will now be automatically added to your Mi account.
Next,enable OEM unlocking and USB debugging under developer options.
Then connect your mobile to the pc or laptop while on fastboot mode. Unlock again. This time, it will be successful!
Same problem. Can't unlock my Mi 5S on Global Stable firmware (V8.0.3.0). And can't flash to China Developer firmware.

Sorry i was on mobile and understood you badly.
According to this:
http://en.miui.com/thread-202290-1-1.html
You should have that parameter no matter you are at global or not, but if you don't you should flash a developer version, instruction at the same page.
Before you say "i can't flash developer rom", did you tried the updater app to flash it?
Force flash your rom using special cable to enter fastboot to install. I dont know its detail, but the installation called Deep Flash using deep flash cable sold on ebay

I had similar problems and I was also trying to figure out what to do to unlock bootloader on Global stable rom. The amount of people having the same problem where unlocking app stops at 50% is overwhelming ,judging from the comments found on google, but the info what is the actual problem is next to none. Suggested solutions looks to me like voodoo and most if not all probably doesn't have any impact on successful unlocking. As the Xiaomi unlock app is just a wrapper for fastboot executable I've checked what kind of commands are being send to the fastboot when you click unlock here they are.
fastboot getvar product
fastboot getvar soc-id
fastboot getvar soc_id
fastboot getvar board_version
So I've checked if I will actually get any info from bootloader if I send those commands manually, and with no surprise I didn't get any. So this was the problem at least in my case. Some kind of connection problem I'm not sure where exactly the fault is, probably drivers but try to issue those commands manually from command line I can bet you will not get any info from the phone. What to do if that's the case remove and reinstall drivers, this is what has worked for me. Good luck
Had the same problem. Got it solved today. the bad news you need a deep flashing cable, good news you can make it yourself.
Here is the guide:
http ://en.miui.com/thread-310325-1-1.html
http ://en.miui.com/thread-299790-1-1.html
I have unlocked 4 mi phones with no difficulty. Some of them with fake/seller ROM. Once you got permission make sure you have done all things right before preceding to Unlock. Usually it's all about loading the right driver for Xiaomi phone. Using default windows driver is not working. As it's not Microsoft signed driver you have to start windows in insecure mode.
You have to login in your mi account both on PC and on phone with SIM card ind.
Check that phone is verified settings/mi account on your phone.
Best luck
Something is with drivers for your phone. I have the same problem...than i delete drivers and than they automaticly reinstall and evarything works.

Follow the guide that I posted to make the cable(first link), install all the drivers and software needed (second link).
After successfully putting the phone in deep flash mode you need to update Qualcomm drivers (under device manager it must appear as com3 or com10 port after that).
Then use Mi Flash tool to flash Chinese dev rom (http ://bigota.d.miui.com/7.1.20/miui_MI5S_7.1.20_229fa68558_6.0.zip). If the flash fails the first time reboot the computer and try again.
After that sync connect your MI account to the device, enter Dev mode and you will find OEM Unlock option.
Not easy but it works.
Good Luck!

I tried all the possibilities described, that do not need flash developer rom using a deep flash cable. I changed drivers and everything, no success.
In time, I already ordered a deep flash cable here in Brazil. For my part, I thank all fellas who tried to help me but gave up trying anything else. As the title of the topic, my device is currently virtually impossible to unlock in the normal way.

I have same problem to unlock Mi5s before but then realize that you need to update driver on your PC from Keadcom (or samething) into Marshall London Bootloader and it success.
Now my Mi5s uncloked officially.
I just use same Mi account which has permission to unlock my previous device which is Mi5.
No need deep flash cable, just normal cable can do.
Hope this help.

Unfortunately this this did not help. My assumption is that 8.0.3.0. Global stable needs ROM-internal permissions, which are currently missing. (In fastboot mode ADB is able to communicate to the phone, so it is not a driver issue.)

I know you probably enabled the options when you first unlocked. But did you enable them again after your device was wipe from the unlocking process?
Can you boot the current rom on your device?
If the rom is not booting, you may need to try and flash stock fastboot rom in EDL Mode (If that is still an option for this device).
Edit: - As you locked the bootloader with fastboot command, have you tried the fastboot unlock command
Code:
fastboot oem unlock
What response are you getting from "fastboot devices" while in fastboot.
also what is "fastboot oem device-info" reporting?

[Link share] Unlock boot-loader with this apk for Realme 5 Pro on Android 10.

I had to upgrade to Android 10 and then follow the steps described here:

Btw., it's better to stick to the official post from realme I linked above, apps and links on youtube could be malicious.
I am using RM5P Indian version. The youtube link is safe. I didn't find any issues.
More than that, this apk was already listed in xda by faisalxp. I realized that late.

Yes, that's exactly what I was on before unlocking and rooting (INDIAN version).
Install adb and fastboot drivers in PC.
Good practice is to put all the necessary files in the C:/adb folder for installing twrp recovery.
Backup your data/pictures/notes etc first to pc.
Enable OEM unlock in Developer options. Enable USB debugging.
Install deep test apk and follow the instructions and get into FASTBOOT.
In fastboot type: fastboot flashing unlock and enter, and then unlock.

Yes, you can use the app prompt "Apply to exit in-depth test". It will reboot to Fastboot where you need to type the command to lock.
Fastboot help - will give you all the commands available.
Commands available:
locking/unlocking:
Fastboot flashing lock|unlock Lock/unlock partitions for flashing
I suggest you research a bit more. Phone might get bricked. Do it at your own risk.
You should not be on TWRP, go back to official recovery.
If you have rooted, UNROOT first and do the rest.

Actually when i press that button it shows this "You can only apply to exit in-depth test after carrying out bootloader lock operation in fastboot mode".
so I went into fastboot mode and used the command fastboot flashing lock it wiped my data and rebooted to welcome screen (language region setup)
Should I now use the app to "Apply to exit in-depth test"? or don't use the app?

What are the steps you took before relocking the bootloader?
In my experience, relocking the bootloader should be the last thing you do, after you've got a working/bootable stock ROM.

So, after i installed the latest stock rom, the device worked normally, but after waiting a while for the oem lock option appear in development options, it din´t show up. so i just gave up and installed lineage 19.1 but if i can i want to lock the bootloader again.
Raphael, I think you might have quoted my post twice, but didn't add an actual answer. Or maybe I'm super blind and I can't see it.

So, the OEM lock/unlock thing comes with a pretty big caveat, and you need to be aware of it: loss of data.
Every time you lock or unlock your bootloader, a wipe data is triggered.
Now, for as far as I know, to lock the bootloader, you need two things:
1. Stock ROM. Don't do this on a custom ROM!
2. following command, in Terminal/Cmd Prompt
fastboot oem lock
Of course, you need to be in fastboot mode, so if you're not, and if you're booted and connected via USB (USB debugging needs to be ON and RSA fingerprinting accepted), do:
adb devices
It should display your device here. This is just to make sure ADB is working properly.
adb reboot bootloader
At this point, the phone should reboot into bootloader, so now you can do the lock command
fastboot oem lock
Data should be erased and, in case it doesn't automatically boot up, you can reboot the phone.
Don't worry about the OEM unlocking option in Developer Options. You just make sure the stock ROM is functional before attempting to relock the bootloader.

So, the OEM lock/unlock thing comes with a pretty big caveat, and you need to be aware of it: loss of data.
Every time you lock or unlock your bootloader, a wipe data is triggered.
Now, for as far as I know, to lock the bootloader, you need two things:
1. Stock ROM. Don't do this on a custom ROM!
2. following command, in Terminal/Cmd Prompt
fastboot oem lock
Of course, you need to be in fastboot mode, so if you're not, and if you're booted and connected via USB (USB debugging needs to be ON and RSA fingerprinting accepted), do:
adb devices

I tried that, and it din´t work, this method is the same that was in a help thread in xda forum of my device, this command works fine in my nexus 6, but on my moto one action it does not, i unlocked my bootloader via the normal method using motorola´s website, not using another method.

But why do you say it didn't work? Do you get an error at any point during the process?

no, i run the command and it asks for changing the oem lock setting in developer options, i reboot the phone and run through the setup process. Then when i enable developer options and check the oem lock option, it is greyed out.
Is it greyed out in the on or off position? Can you attach a screenshot? I don't remember the operations sequence... But I think the option was automatically switched back to the original position (off) when you lock the bootloader. I could be wrong though. So...when you run the "fastboot oem lock" command, it asks you to....what?
Set the option to on or off? Some screenshots from both the PC, with the message, and the developer options might help to clarify this.

it is greyed in the on position, i can´t add a screenshot because i am in lineage 19.1 with root and the option shows up,when i run the command in cmd, it says to me to check the oem lock option in developer options

A screenshot would be really useful. But don't worry about it. When you're back to stock rom and ready to lock your bootloader, we can resume this then. I think either we're missing something, or it's everything ok, and you just need to switch that option off. Though, I remember I didn't have to do it manually. But I could be wrong though.
So, don't worry. Enjoy LineageOS and we can resume this when you're back to stock ROM and ready to lock.

so after running the fastboot oem lock command, it asked this in the cmd
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot oem lock
...
(bootloader) Check 'Allow OEM Unlock' in Android Settings > Developer
(bootloader) Options
OKAY [ 0.080s]
finished. total time: 0.080s
when i rebooted the phone, it showed the screen saying that the bootloader was unlocked. also i had to re run the command because it was going to erase my phone but that din´t happend, after going to developer options the option was still greyed out.
The last 3 days i've tried some roms from here.first i've unlocked the bootloader in developer menu,then from fastboot with the unlock key provided by motorola website,i've tried different rom,didnt like that i cannot use bank apps.so i went for locking.full reset,adb enable,reboot bootloader,full flash stock rom (last one from Motorola),reboot to check,adb enable, reboot bootloader,run command " fastboot oem lock " once ,it asked for confirmation due to data loss,then run command " fastboot oem lock " once more,then reboot to os.everything went ok,device dont show that was unlocked

General ROOT RED MAGIC 8 PRO V3.18

ROOT RED MAGIC 8 PRO V3.18​Your device must be bootloader unlocked
To unlock bootloader enable oem unlock in developer options and usb debugging
Then type the command: adb reboot bootloader
Or access fastboot with hardware key: Power + volume down
Once in fastboot type the following command to unlock:
fastboot flashing unlock
fastboot flashing unlock_critical"
Access fastboot then type the command:
fastboot flash init_boot_a magisk_patched-25200_3.18UN.img
fastboot reboot
Done
You check if the correct active slot is a, if it is b just change the command a with b
Only use for V3.18 version I have not tested other versions
Note: Absolutely do not patch the boot file, you will have a continuous boot error​
Root Done
The backups with just ommiting the B slots is 12.7 gb so i cant personally help you with that. Have you tried flashing the OTA's boot.img (might even try boot_a.img) and init_boot.img while slot A is selected? Not the magisk modded files either.

i flashed those 2 files but still can't boot the phone, go to logo then turn off the screen, can only go to fastboot and recovery, i sideload 47% it gives error
If you are rooted, please help me, I will send you coffee donate, please help me, full backup
I Pm'd you the backups now that i am at home, hopefully they help
Im at a stand still with this. I have already fastboot flashing unlock_critical as you can see in which it states Device already unlocked but whether I am in bootloader and fastboot I get Flashing is not allowed in a lock state. Any help from some else that ran into this or has knowledge on it?
Thanks
Update. Fixed the issue. Add the step of "fastboot flashing unlock" before "fastboot flashing unlock_critical"
If You can flash a GSI, It'd be a decisive factor in getting people to buy this phone. The company should be paying you to do this, but they're probably too greedy to make a bigger profit
I've successfully flashed a few A13 GSIs but screen lock is a still a problem and so far calls and messaging doesn't work normally.
I know that this next question were asked before, but i keep not understanding much about it: if i revert back the root completely (unroot the phone, lock the oem and delete "third party apps" like magisk, etc.) will my warranty be back? i am talking about the redmagic 8 pro void specifically. Can someone help me understanding this? i have searched on internet about this and they all say that simply it depends on manufacturers to "detect" if the warranty was void (even if you unroot and lock oem and all).... Thank you in advance

Well once you unlock bootloader it clearly says warranty: void in fastboot so it probably is very easy to detect

In that case, why op said that the warranty can still be returned after relocking the bootloader?
As you see, it is very connfusing... Some guys say yes, some others not. :s

Did you follow the instructions correctly, this error may have you flashed the wrong boot file, right?

Yes, I unlocked the bootloader first.
Then I flash boot and an error occurred.
Did I get a brick or is there hope?)
