Redmi Note 9S (Curtana, Global?) not fixable boot loop

Hey Guys,

i have the Redmi 9S Curtana Smartphone. Buyed in Germany. So i dont know if i have Global or Europe Version.

Modelnumber on the Backside: M2003J6A1G

I had Lineageos 18.1 official installed with Lineageos 18.1 Recovery along with it.

Today i decided to install MIUI again.

Used Miflash Tool and curtana_global_images_V12.5.4.0.RJWMIXM_20220211.0000.00_11.0_global_c3215d4c09.tgz

And now i have a Bootloop that i cant fix. (it shows "Redmi powered by android", vibrates, and then restarts)

Even if i reinstall lineageos recovery and then lineageos self, boot loop still persists...

Tried XiaoMiTool V2 too. Tried other recoverys and ROMs. No single one works any more.

Could somebody help me?

Thanks.

IDK if you already did it, you should use format data.

Try with other ROM version

Have it done it every time. No luck with that.
Try with other ROM version
I try a Android 10 Miui one, and then i give report.

Ok, tried now to Flash curtana_global_images_V11.0.3.0.QJWMIXM_20200318.0000.00_10.0_global with no luck.

All Flashtools says that the Device is locked. And cant unlock again because MIUI dont boot...

Edit:

Tried it anyway:

It seems you did relock your device. As it is locked, can't be flashed through fastboot, only EDL, but you probably need an authorized account to use Mi Flash tool.

So, i can throw it into garbage... I already searched in the internet, the repair cost to much. for that money i can get a new one...

But that wasnt the goal. Indeed i relocked it. The Goal was to reflash it to stock MIUI ROM (wich is really easy and already did it with the note 8 one in the past), and to sell it, because i got a new phone.

So, **** happens

Actually is very tricky to flash a Xiaomi powered with Qualcomm, specially when the bootloader is locked, even in unlocked devices, sometimes is required an authorized account to proceed to flash.
It is highly advised to not re-lock bootloader when attempting to recover the device, otherwise you'll be forced to use only EDL mode.

It's not that your device "is not properly in fastboot" most likely, that you need to update the drivers correctly, so your PC can detect your device.

This may mean drivers are not installed or missed. Instead, you have to see if there is some hardware variations while you attach the device to the PC.

Assim, posso jogar no lixo... Já pesquisei na internet, o conserto custou caro. com esse dinheiro posso comprar um novo...

Mas esse não era o objetivo. Na verdade, eu o bloqueei novamente. O objetivo era reflash para armazenar MIUI ROM (o que é muito fácil e já fiz isso com o note 8 no passado) e vendê-lo, porque ganhei um telefone novo.

Então, **** acontece

Eu consigo recuperar seu aparelho, porém tem um custo do apk que eu utilizo, cerca de $25 /30 usd , depende da situação que seu celular ficou
