Are you trying to use the same account used before?

Did you login to your account in miaccount?
[Redmi Note 9 Guides, News, & Discussion] Jazzda:
Yes, in my account I have 2 phones, a redmi 7A and now a Redmi Note 9. Both are detected in miflash_unlock 3.5.9
[Redmi Note 9 Guides, News, & Discussion] VD171:
Probably that is the problem.

This is issue is with xiaomi and not with you or your computer.
[Redmi Note 9 Guides, News, & Discussion] Jazzda:
So you mean I should create another account for the new phone?

The software is amazing btw
[Redmi Note 9 Guides, News, & Discussion] VD171:
May you attach the screenshot of the miunlock status inside the settings of the device, please?

I had same problem because I tried to unlock more than one phone in a short time.
[Redmi Note 9 Guides, News, & Discussion] Jazzda:
Well, it's in portuguese, but basically it says that the device is blocked, the phone is safe, then they try to explain why it is blocked, and finally they say that if I need to enter fastboot to restore the device I must unlock it first.

So tired of xiaomi bull **** :mad:
[Redmi Note 9 Guides, News, & Discussion] SubwayChamp:
I think first you have to bind successfully your Mi account to the device to can go to the next step, and for the next step I prefer the official Mi unlock tool over the Xiaomi v2 tool.
[Redmi Note 9 Guides, News, & Discussion] VD171:
Apparentely, that is a problem with binding account.

Did you try other SIM cards?

(Aparentemente, este é um problema na vinculação da conta. Você tentou usar outros chips?)
[Redmi Note 9 Guides, News, & Discussion] Jazzda:
These are the devices that are listed im my Mi account (https://account.xiaomi.com)

The first one (M2003J15SC-Red) is the Redmi Note 9 that I want to unlock, the other one is already unlocked.
[Redmi Note 9 Guides, News, & Discussion] VD171:
When did you unlock the another device?

(Quando foi q vc desbloqueou o outro aparelho?)
[Redmi Note 9 Guides, News, & Discussion] Jazzda:
2 years ago in September
[Redmi Note 9 Guides, News, & Discussion] VD171:
That's fine.

You need to keep trying everything you can to get the solution.
[Redmi Note 9 Guides, News, & Discussion] SubwayChamp:
It's not enough with just logging in to your Mi account, you also have to bind your current device to it, try inserting your SIM to the slot 1 (or switching it to the other slot), you have to switch off Wi-Fi and enable mobile data, also try with logging out from your Mi account, then restart your device, logging in again and accept all the conditions from Mi cloud to synchronize with (later you can change that), in the case you actually don't own the Redmi 7A then disconnect it.
[Redmi Note 9 Guides, News, & Discussion] Jazzda:
The two phones are active, each one with his own SIM.

I did all that but accepting Mi cloud synchronization. I have lot's of data in the phone already and don't feel safe by giving it to someone in china. It must be illegal to force people doing that, right?

I will make a factory reset and proceed as you say.

Thanks a lot 🙏
[Redmi Note 9 Guides, News, & Discussion] VD171:
Nobody in china wants your data.
[Redmi Note 9 Guides, News, & Discussion] Jazzda:
Someone from a Mi forum provided me with a new unlock tool from xiaomi that works.

I must wait 168 hours before unlocking but it seems that my problem is solved.

Thanks for your support 🙏
[Redmi Note 9 Guides, News, & Discussion] Jazzda:
I need a small advice.

In the meanwhile the phone firmware was upgraded from Android 10 to Android 11.

I want to go back to Android 10, so if I make a factory reset would it revert to Android 10? And will it keep the unlock state?

Good work, my friend.

You are welcome.

[Redmi Note 9 Guides, News, & Discussion] VD171:

But if you downgrade to Android 10, you may need to wipe data too.

Dear VD171, your Merlin guide is very good, but I think it misses a guide to install GSI.

I'm trying to install a GSI (LeOS) for a couple a days, but the GSI never starts, it stays in bootanimation forever.

Dear VD171, I think I have an unusual issue and need your help.

After reading a few threads decided to downgrade from V12.0.10.0.QJOEUXM --> V12.0.4.0.QJOEUXM to be able to install some TWRP.

MIUI was working fine, but couldn't get a GSI to work, so after lots of tryings I gave up and decided to flash stock again (v12.0.10.0).

I executed flash_all.bat from within fastboot and MIUI was full flashed without errors.

But now it is in bootloop, only showing the unlocked status icon on top, big "Redmi" on middle, and "powered by android" on bottom for a few seconds and restarts booting.

I tried to Wipe Data from stock recovery and flash stock again, but with the same result.

What can I do?
[Redmi Note 9 Guides, News, & Discussion] SubwayChamp:
To call some specific user you have to quote using @ preceding the username otherwise if they are not visiting the thread for a certain time, XDA won't update them.

Like your bootloader still remains unlocked, try firstly flashing the patched vbmeta.img that is in those threads and try to boot.

If it is not working, you may flash the firmware using the Format all option (not need to re-lock) and through EDL mode, personally this gave me better results over fastboot method.
[Redmi Note 9 Guides, News, & Discussion] Jazzda:
Thanks for jumping in 🙏

Using what tool?
[Redmi Note 9 Guides, News, & Discussion] SubwayChamp:
Using SP Flash tool, there is an option in Format tab to wipe all except bootloader, I think you read the guide to bypass an authorized account and can use it, didn't?
[Redmi Note 9 Guides, News, & Discussion] VD171:
You do NOT need to downgrade your MIUI version to be able to use any recovery project.

I suggest you to try all recovery projects, if you can.

Flashing recovery does not brick your device, you can flash another easily and safely.

I suggest you to flash recovery using fastboot.

Certainly, more than one will works to any MIUI version.

Now I'm trying to unbrick using XiaoMiToolV2, but it's downloading the last version (R) and I will need to downgrade to 10 again, if it can unbrick it

The bootlop happens after flashing the stock miui, so the recovery is there

Anyway, I'm givving up of TWRP
[Redmi Note 9 Guides, News, & Discussion] Jazzda:
It's possible that this happened because I started MIUI without a SIM card?
[Redmi Note 9 Guides, News, & Discussion] SubwayChamp:
No, I know it, I didn't refer to the Format All option in the main menu but the option that it is in the Format tab that anyway have to be marked, and checking the option Except Bootloader.

[Redmi Note 9 Guides, News, & Discussion] VD171:
If you flashed the stock MUIU but it keeps on bootloop, probably you need to format data.

If you flashes stock MIUI and your device keep in bootloop, certainly you need to wipe data or flash the EXACTLY SAME miui version of before, when the device was working.

I tried that too with no avail.

Then I got a link from someone to an official TWRP for merlin (from twrp.me) but it was for Motorola Moto G Turbo, also named merlin.

Now not even the hardware buttons work, so I'll take it to a support store, and I hope they can fix it.

Thank you for your support
[Redmi Note 9 Guides, News, & Discussion] SubwayChamp:
I think you are not trying exactly what others are advising you should do, you are in your own trying things out of scope. The links for TWRP are very clear in the various guides provided by VD171.

The better is using simply the SP Flash tool with your device completely off, READ the thread to bypass the EDL authorization and all will be OK, recover first the ability to boot and after try again to customize it always that you didn't have a mistake and flashed something for other device that worst the things what I'm starting to suspect.
[Redmi Note 9 Guides, News, & Discussion] Jazzda:
I've read a lot of stuff about sp flash tool, but it's the first time someone tells that the device needs to be completely off. That's why it just sits there for more than an hour doing nothing.

Now it's too late, the phone is fully charged and will take days to drain the 5A battery.

On monday it goes to a support store hoping they will make it boot again.

(y) 🙏
[Redmi Note 9 Guides, News, & Discussion] SubwayChamp:
Completely off means that you have to shut down the device, not that the battery has to be drained. When the device is off connecting it to the PC while you press volume up it would work too, if the device is not recognize properly it could be hours, days, no matter, nothing can't happen in this stage. The guide to bypass EDL authorization is a must-read too, otherwise your device won't pass from BROM to bootloader and SP Flash tool won't see it.
[Redmi Note 9 Guides, News, & Discussion] Jazzda:
I can see some light at the end of the tunnel :)

After only one night the battery drown completely, and I was able to make spflashtoo detect my phone.

Now I need some guidance, please:

My device had v12.0.1.0-RJOEUXM installed, abusively auto updated from v12.0.10.0-QJOEUXM, which means, it was upgraded from A10 to A11 without a simple warning. I wanted A10 back and was able to successfully downgrade it. So far so good.

It was bricked while on 12.0.10.0-Q, after flashing a twrp for a motorola also called merlin.

This is what I think I can try now, with your bless and approval: (y)

1. Flash (in Download mode) ONLY bootloader from v12.0.4.0-QJOEUXM -> how? spflash tool complains about authorization

2. Flash (in Download mode) v12.0.10.0-QJOEUXM, leaving bootloader un ticked

If this is the correct approach, how can I bypass the error about authorization?

I've read this but couldn't get any conclusion

Direct links to the needed files would be nice.

Thanks a bunch 🙏🙏🙏

[Touch Diamond, MDA Compact IV Themes and Apps] Pugzi:
Hi all,

Since the Touch Diamond has accelerometers in the X Y and Z space axis, is it not possible to try and create an Inertial Navigation System. For those who are not sure, it INS uses the accelerometers to assess the movement of the device. So long as the user states the start point and north orientation do you think it possible to do it and to create the software. If it is, then we could do without GPS, afterall, aircraft have used INS for a long time now (albiet theyalso used a gyro). It's not as accurate as GPS but it'll certainly work as a navigation device.

Any comments or help in doing this?
[Touch Diamond, MDA Compact IV Themes and Apps] beemerTPPC:
Some GPS systems use inertial navigation for better positioning when in tunners or low coverage areas.

The idea could be simple, a program that read the GPS data, mix them with the G-Sensor data and (why not!) with the TMC data recovered from the FM radio and publish them in a new virtual serial port.

But doing it is not so simple :(
[Touch Diamond, MDA Compact IV Themes and Apps] Ikari:
I think its not dificul to trie i already post the idia in other forum, get the gps data, mix whit the acc, and start counting speed changes in forward . left/right and i think we can get a 600m bonus before black out.

600m whit simple formulas, complex ones give you much more.
[Touch Diamond, MDA Compact IV Themes and Apps] dan168:
The idea is simple yes - implementing such system is a lot more difficult than one could imagine though. It'll only be accurate for a short distance, before the errors become so large it's not feasible (due to double integration).
