Question Unlock Bootloader of Redmi 8A Dual - Xiaomi Redmi 8A Dual

I ve been trying to unlock the bootloader for a week now.
I am stuck at Developer Options > Mi Unlock status > Add account and device.
It throws up the error "Coudn't add, Device basic data authentication failed"
What could be the issue, any help / pointers will be appreciated.

I think you need to turn off wifi and enable mobile data then goto developer option and repeat the process.

Thanks, I tried but still not working.

There is no possible solution for this particular problem. We're constantly checking everyday but apparently its MIUI problem they messed up something in new update. Wait for Aug update.

Dark mode is far more better now
Full screen gesture is available now ( swipe up from bottom and side to navigate ref - Google android 10 updates navigation gesture)
Jiocall app works well no issues ( I am mentioning this because jio call app was not working properly with Android 10 on other brands like realme they are trying to fix..)
And now also the bootloader unlocking not working.. now also the miflash_unlock application shows failed to unlock..

Can we flash the lower version of miui roms by this meathod
https://www.google.com/amp/s/wasconet.com/flash-rom-xiaomi-phones-locked-bootloader/amp/
Without unlocking bootloader. (Device is at latest update) so not possible to unlock bootloader.

This method doesn't work on newer devices, as the edl mode is locked and only accessible by opening the device's back case and shorting the edl flash point. Even after that flashing permission would be needed to flash via official mi flash tool which users can't get.

Excalibur, leave that bootloader issue first my device IMEI number is not getting verfied with the Flipkart exchange and the device exchange value is also very less its 1,680 without IMEI verified.
and then the mi suit does even recognise this device why I don't know.
And it's a 32 bit device that's a bad issue for gcam lovers too.,
Good things with this device that
Storage space 32 gb I have
(And that too this device doesn't support ExFat file system on as card)
Type C ( but its of no use without fast charging ) may be we can use this type c for audio output (again the audio drivers or hardware is of no best for orginal audio quality) you have to use mausic player like jet plus pro app to tune it .. if it's rooted then V4A viper 4 Android.

It supports 18w fast charging, you just need a fast charger to do that which doesn't come out of the box. I've been using a fast charger and it charges as quickly as rn8 pro or any other 18w supportable device.
There isn't anything wrong with the audio quality provided by the inbuilt dac, it's the same as any other phone in this price point or any devices costing even higher than this. And viper4droid does more like tuning the eq which again would be of no use if the device's dac is bad.

any update guys?

your link seems dead or not correct. - edit: link correct, was not working due to my vpn...
I assume he patched a G8+ boot.img with magisk manager.
boot image can be extracted from official Doha firmware found here: https://mirrors.lolinet.com/firmware/moto/doha/official/
manual on how to do this can be found on official magisk manager website.
be aware that when unlocking bootloader your phone will reset to factory settings.
This is what I did. Yes..
Worked great for my G8+. I guess people should just check which stock ROM file they get from lolinet to make sure it's the right one. I say that because, in my case, lolinet list had two files for the Brazilian stock ROM. I went to Settings / About / Version number and downloaded the matching file. Don't know whether the other file would work the same or not. Just didn't want to risk having any issue since G8+ is somewhat new and there's not much info on solving root problems on the Internet.
Hi,
Couple of questions
Does the Bootloader have to be Unlocked to flash the modified Boot image?
Or can I use update option?
Are Motorola releasing unlock numbers for Bootloader now?
Thanks, Carl

Hello, Carl. I guess it's not possible unless there's a flaw in the security. There are some articles on the Internet about that. Google "is-there-a-way-to-root-an-android-phone-without-unlocking-the-bootloader". I can't post URLs yet.
As for Motorola devices, I was able to unlock the bootloader without problems on my G8+, last week. The only caveat, I'm my case, is that I had to wait some days for the unlock bootloader option be available under developer options. It was disabled by default in my G8+. And, yes, they're releasing bootloader unlocking codes.
THANKS!
Have anybody with a rooted device tried to get wide angle camera working in gcam ports?
Thanks.

magisk module debloater and also sdmaid helped with most of the bloatware, the only thing I could not remove was google files but I just deactivated it.
a really weird thing happened with the April 1st update, basically the update started automatically and it failed at 3/6 so I tought I should restart my phone and test it again, but it got stuck in bootloop and I had to reflash a rom with fastboot cmd.
I think that's because I unlocked the bootloader and rooted my phone, cause u lose the right for updates after you do that, but for some reason lenovo/moto update system goes automatically the next second u connect to the internet and fails halfway thru so u have a higher chance to ruin your phone or something, instead of denying the update from the start
so the solution I found was to try and delete "moto update service" app that I can't force stop or disable but I couldnt find it in system/app or system/priv-app, that's because the app name is "3c_ota", so deleting that with SD Maid app worked and the "update system" option in settings is reverted to a sort of default android one that lets you check manually.
Had a similiar issue. I soft bricked my phone (bootloop) and installed a stock rom from an unofficial source. The funny thing is, this version did make like 3 or 4 system upgrades to PPSI.29.65-51 without any issue. But the 1st April updated failed to install. I then flashed the official 1st april stock image with the moto rescue and smart assistant. After that, the official ROM tells me my phone is not allowed to do updates because the security of this phone is compromised and I should contact lenovo support
Those upates are kinda annoying if they don't work, I guess I'll just completey flash the phone every 6-12 months with the moto assistant.
yeah you should always have a backup rom that you can download with moto assistant or from lolinet g8 roms (https://mirrors.lolinet.com/firmware/moto/doha/official/)
I also got the same message saying that my phone is compromised ( unlocked bootloader + rooted) and it won't receive any further updates, but I just deleted the "3c_ota" app (the moto update service) which is bad cause if forces automatic updates the second u connect to internet.
I'm not going to touch any further updates or security patches until android 10, which I will attempt to flash via moto assistant

SM-A205U (MetroPCS) OEM Unlock

Hello,
Just wanted to share this with the community as I found this just yesterday. If you goto your settings and click connections then "More connection settings" towards the bottom there is an option for "Network Unlock". I did this like I said yesterday and it permanent unlocked the phone. I don't have any other SIM cards to try and see if it will go on a different network but just wanted to point this out to the community!

That's not an OEM unlock, you've only unlocked the SIM card lock.
Into the sun you go
I wondered if this was either effecting, &or blocking or stopping oem unlock from showing or being visible? Just a thought.

It's our specific model.
There are no 205u units in public domain that exist with an oem toggle.
It's disabled by default in the 205u source.
The only way this might be possible is with combination firmware but in all my searching so far i have yet to find bootloader 5 combination firmware ...
If anyone can find me a bootloader 5 android 10 combination firmware for the 205U varient i would be willing to see if there would be a way to get this rooted and bootloader unlocked

The combination file is from an older bootloader, so it retains the most recent bootloader to maintain integrity of the Qfuse.
That's kinda why we want the combination file for 10, the bootloader hasn't changed which means the file would be universal for anyone who updates.

To many threads, what are the steps to change the original OS ?

Hello all,
I have read so many threads, and finally I'm still not sure to have the right method.
My current config has no more memory to update apps so I need to do something ! Here are the details :
Huawei P8 Lite 2017 (PRA-LX1)
build : 8.0.0.402 (C432patch01)
EMUI : 8.0.0
Android : 8.0.0
After reading several threads, here are my questions :
1. I have to use DC Unlocker --> is it always mandatory ?
2. Which TWRP do I have to use ? (link please, I'm completely lost, an still doesn't know which one to download ! :angel: )
3. LineageOS 15.1 seems to be the best choice (battery stamina), does it work perfectly ? (GPS, camera...)
4. What about Treble Project ? I still doesn't understand it is a better idea, how to install it, which ROM to use...
Thanks for all of your replies !
Hello,
DC-Unlocker is mandatory if your bootloader is locked. Recently, TWRP went official on P8 Lite 2017 devices. You can grab it from the official TWRP website (can't post links as I am a new user, search for 'prague' in the device list). I am using LineageOS 15.1 on my device and it's working flawlessly.
I use chimera to unlock bootloader.
But every custom to a have to flash isn't work. Boot loop or other issuses, like "device is uncertificated" so any google apps don't work.
Do i need to decrypt memory? To flash corectly custom rom.
Finally i have only root, and clean all brand apps.

1. Download DC Unlocker from GPlay, buy credits (it will send you username and password to your email)
2. Download DC Unlocker to your pc, in phone allow ADB debuging and HDB
3. Type into call app '*#*#2846579#*#*', tap on 'Background settings', next on 'USB Ports Settings' and select 'Manufacture mode'.
4. Plug your phone to PC and click on 'Detect device' and allow all stuff that will pop up on your phone.
5. Click on 'Server' tab (we are still on PC) and enter username and password you've got from app and 'Check login'.
6. Click on 'Unlocking' tab and choose 'Unlock bootloader code'. And your code should popup in text log.
7. Let's move to your phone, go to settings -> developer settings -> Enable OEM unlocking, enter your password.
8. Power off your phone and when it vibrate push Vol - and Power button at same time.
8. Plug it back to your PC and start Command prompt, enter 'fasboot oem unlock 00112233445566778899' (use your code).
9. Now just accept unlocking and formating all your data on the phone.
10. Download TWRP and let's flash it using command 'fastboot flash recovery_ramdisk twrp.img' (if your command prompt is in for example C:\Users\Pepege just cd to your Downloads directory where is downloaded .img file)
11. If it's succesfull just type 'fastboot reboot' and keep holding volume up, if eRecovery pops up click on reboot and this time hold volume up and down (idk why but sometimes works this and sometimes this combo)
12. If you are in TWRP just format DATA, CACHE and Dalvik Cache partition, make backup (if you wanna) and now flash whatever you wanna. LOS, AOSP, it's on you.
Also if you wanna LOCK (not relock) your device, download HuRuUpdater, download oldest version of Android for your model and region (C432 in this case) and flash it, after you reboot from recovery go to bootloader (fastboot mode) and type on your pc 'fastboot oem relock 00112233445566778899' then 'fastboot reboot' now do first setup, go to developer options, disable 'Enable OEM unlock', format data again (to be safe) and you are ready to go, after updating to oreo relock status should change to locked.
EDIT: Adding random Youtube video just in case https://www.youtube.com/watch?v=pclEmwt5C84
EDIT2: Project treble is simply stuff splitting system from vendor, it's on every device runing on oreo or better, more here https://www.xda-developers.com/goog...ze-android-so-oems-can-update-devices-faster/
Also for me best ROM are AOSP 10 and LOS 17.1
No custom rom wanted to boot. The method on this page will not work. All that's left for me is to decrypt the phone's memory. but then knowing that the weekend was over and I needed a phone call on Monday, I just let go.
@DunoCZ
What a great post, thank you so much !!!
Some people have reported more battery consumption on Lineage 16 and 17, compared to 15. Did you test all of these ROM ? Are there people here who have some feedback ?
@flgmnft
If I unterstand well, I need to extract fstab file from the ROM archive in order to remove the encryption : can you confirm or explain me what to do ?
@ilakhnon
It seems you don't have the encryption problem, what is your opinion about it ? did you edit the ROM fstab file ? other ?

hummmmm.... bad news : my phone is not detected by DC Unlocker !
I should have tried before buying the license, but it doesn't matter.
But don't you find it strange ?
oh... I didn't read it correctly, the P8 Lite 2017 is not supported, only the P8 Lite (that was my mistake).
But I wonder if I really need it, because I bought it "sim unlocked", what do you think about it ?
EDIT : in other words, how can I know if I can erase the original bootloader ? (adb method)

Then try using hisuite to downgrade to nougat, but after unlocking upgrade to oreo to have treble enabled.
I'm waiting for an answer from DC unlocker's developper, and I will test this solution if I don't have another choice.
(I don't know if it is easy to downgrade with HiSuite, I've never used it, I will see that later).
Thank you for your help.

Hello @DunoCZ,
I was thinking about this post... I won't need to unlock the bootloader if I downgade to Nougat ?
Is there a topic talking about it ?
EDIT : Sorry, I didn't read correctly your post. Unlocking will probably be mandatory, so it doesn't change anything for me.

There's no problem unlocking 2017 with DC Unlocker which I did two days ago.
Install HiSuite and run it once to be sure you got proper drivers and make sure you put USB into manufacture mode.

I had the same issue, and contacted dc_unlocker's developer. Basically, the software can read the bootloader unlock password if it just discoverer the phone's port, even if does not seem to recognize the phone. I had to go ahead an got the code, for 4 credits/€
I'm also interested in knowing what is the best overall ROM these days in terms of compatibility and battery consumption!
Hello all,
Sorry for my silence, I had to go back to work, and after a few days I was seriously ill. I begin to recover some energy, it's not great, but enough to come back here... and because my phone, stiill with the original system, becomes really too slooooooooooooow !
@buteo : Do you confirm me I can go further with DC-unlocker software, in order to unlock the bootloader without any risk ?
@All :
As @Natural_High asked, which ROM is currently the best choice ?
Thanks for your help !

You can use DC-unlocker, it's safe. I used it myself a couple of months ago too.
Regarding the ROM, I haven't tried any Android 10 or 9 ROMs. From what I've seen, people say it's still a bit too buggy, so I went for LineageOS 15.1 and it worked fine. I did some tests, since I don't use it as my daily driver, but eveything seemed to work fine! anyway, feel free to try some of the newer ROMs and let us know your opinion
Thank you very much for your answer !
Lineage 15.1 was my preferred choice, I think I will use it.
I hope I won't have any issues, since I really need my phone...
Let's go for backup...

Question how to unlock my bricked Redmi Note 11 Pro 5g (China:Pissarro) Bootloader

hi, i updated my phone to MIUI 13.0.3 android 12 and i've noticed a bug that made all the apps that are using the camera like instagram and snapchat take blurry pictures like an effect getting applied to the pictures taken by those apps (everything normal in my stock camera app) so i decided to use MiFlash tool to flash the previous android version on my phone but i bricked my phone instead i flashed a global rom while my phone is the chinese market version and accidently checked the ClearData+lock Device check box in MiFlash. the tool flashed the rom successfully but when the phone restarted it showed me a message saying that this rom cannot be installed on this device in recovery mode i couldn't do anything after cuz the bootloader got locked too T i tried everything to unlock it (mtk Client - bootloader unlocker+ adb fastboot + Xiaomi Unlock app ...). please help me is there any way i can fix my phone and what is the righ Rom to flash on my phone (Redmi Note 11 Pro 5G China (21091116C - Pissarro). thnx
friend I'm not a star I tell you how things are 1) you can't go back with another Rom only china 2) anti-roll-back 3) MiCloud you have to disable it you can try MiflashV2 there is also to unlock the bootloader it does everything even the firmware remember if the firmware does not start. important not only china also not china for updates remember first you do the factory reset put google account do not update any app except google drive backup with drive if it has arrived update it is better by setting the time instead of downloading the package the problem is when the update occurs it fails to close all active apps and then there is MiCloud that blocks. Best wishes and good luck and that I have little time for me too much trouble here in Europe.

currently my phone is stuck at the logo and after seconds it loads Fastboot automatically i cant access the phone os to do anything i used the xiaomi bootloader unlocker app that works online but it didnt work . the local cell phone service shops told that they have to open the phones back case to fix it ... i dont want that i've just bought the phone didnt even use it for a whole month
they don't have to open it they use licensed or dongle software (USB type) currently I use unlocktoll.net but if the phone is under warranty and you haven't removed the bootloader before it is better for you. It is possible that others have the same problem as you. Good luck

Rule number 1 for Xiaomi never flash anything on Mediatek devices, it will fail. If messed up, no way back as Xiaomi locks the devices for autorized service providers or local Xiaomi branches only. If you want to play with Xiaomi custom roms/development/etc. related only buy Snapdragon based devices.
I i.e. learned it the hard way, when this all started with the Redmi Note 8 Pro, I bricked it by flashing twrp in Android 11 and Xiaomi didn't want to repair it, so I had to pay some russian guy to fix it via Teamviewer with a modified unlock tool which was able to answer the unlock requests by pasting the answer manually from a generator. It's not like I messed up at a point, it's just that Mediatek devices easily fall in a unrecoverable state. In my term it was the combination of Android version and twrp. You will note there is no Mediatek support on xda and even when your device is named like a Snapdragon version, your device is offtopic here, because trying anything on it beyond unlocking the bootloader is harakiri
how to unlock my bricked Redmi Note 11 Pro 5g (Chinaissarro) Bootloader​
Congratulation. Brick without unlocked BL :/
my opinion: you are done....
Some Xiaomi devices have pins on motherboard to
switch EDL, but i dont know with this device.
Try complaint and say something like: "my phone was upgraded and then i see only logo"

I did the same with my device. You can fix it using the MTK tools guide. Its lengthy but easy.

rule #1 with Xiaomi - bootloader is unlocked

Cannot upgrade to 12.5 MIUI

I have a Russian (thanks Amazon !!) Redmi 9a 32Gb/2gb. It is currently running latest 12.0.x ROM version, but i would like to upgrade it to 12.5.
I see on xiaomi ROM site there is currently a 12.5.x version for Russian version, but the OTA never arrived and if i download the recovery zip file and install it manually, it fails verification and stops.
Is there a way to install 12.5 without unlocking the bootloader ?
Is 12.5 supported on this specific redmi 9a ?
thanks !
mmm... spflashtool might work, but Ive only ever used it on a bircked device to unbrick it, never on a functional device to just change the ROM version, but if you really wanna do it without unlocking bootloader thats your best choice.
I will say anyway, its probably safer to unlock bootloader install recovery and install the rom from there, its your call tho.
Heres how I unbricked my device

Right now I cannot unlock the bootloader, maybe in the next months I might try (I want to wait for the warranty to expire). My concern is that my version of Redmi 9A with just 2G of Ram is actually not compatible with MIUI 12.5. The 12.5 rom is actually available, but OTA will leave me in the 12.0 branch and verification fails if I try to install the ROM manually. I would not want to brick it by installing an unsupported ROM.
My phone model is M2006C3LG and the ROM I have right now says I have 1.8Gb of available RAM, I don't think you have a different device from mine.
Im a total n00b so I may be wrong about this next thing, but, I think the only difference is what version of MIUI they were sold with since the hardware doesn't allow downgrades further than the stock ROM that came with the device.
There is always antirollback after MIUI 10, but I think its even further locked for the original stock ROM that came to the device, but yeah, this is all my own speculation due to a bricking incident I faced.
The model number is the same, but the 9A was available with different sizes of RAM 2 or 3 or 4 Gb. Mine is the low end 32/2 which is the model still on sale today. If you still have 1.8 Gb of free RAM you very likely has the 3 or 4 GB model.
Maybe you are right, the OTA allows only for updates within the same MIUi version; I saw several guides on-line and i think i will try the miflash tool and switch to the global version. I have to find a way to unlock bootloader without Xiaomi account (no way in hell I'm signing up for that) and without sim card (this phone is used as a smaller wi-fi only tablet). There are some tools for an offline unlock, I will try those first.
It is incredible how Xiaomi is making it complex just to update to a stable official ROM; given also how much bloatware is shovelled with the stock ROM, I'm not sure I will ever consider Xiaomi again.

In my opinion, DON'T UPGRADE. I upgraded it with recovery and fastboot and my phone got an message everytime when I boot it : dm verity corrupted and I will need to press power button again to work. Maybe i didn't did that correctly ( I have Global 12.0.20 32/2gb)

Thanks for the info. So you upgraded to latest 12.0 without moving to 12.5, any reason for not trying 12.5 ? The phone is currently barely usable with Android 10, maybe Android 11 is even heavier, but why not give it a try ?
I saw several youtube videos and guides and by using MI Flash with a Fastboot image (scattered tgz) it should be a total reflash of the phone.
