[Redmi Note 8 Pro Questions & Answers] avdo06:
Hi, everyone. A very desperate owner over here...So, I am having no response from my Redmi Note 8 Pro. I unlocked bootloader, flashed the "lk" and "preloader" files to prevent hard brick. Then I flashed recovery.img from LR Team. I formatted the data and flashed the latest version of MIUI 11 for Europe (miui_BEGONIAEEAGlobal_V11.0.2.0.QGGEUXM_a13b9653ba_10.0). Everything went without problems. I went back (didn't restart) to recovery, and I chose the "install root" option and flashed Magisk. After that, I restarted the phone. But then the problems started with the phone bootlooping. So, I thought, I'm gonna do all these steps without the "Install root" to see if anything changes. So I flashed "lk" and "preloader" (just to be sure), and I flashed the recovery. After that phone doesn't even bootloop. It just vibrates vey shortly if I hold volume+ and power. No panic just yet, I go to SP Flash Tool, load the firmware scatter file and I press "download". But the tool gives me an error "status-brom_cmd_send_da_fail (0xC0060003)". I have tried different usb ports, changed the usb cable, different button combinations, changed between MTK_AllInOne_DA. bin and DA_PL.bin but without success. So I'm asking you all is there some step that I am missing? Because I have been all over XDA these last couple of days and no solution is working for me.

So I have managed to unbrick my RN8P. It was dead, without fastboot or any other way to connect. Except for SP Flash Tool. But I had no success to connect my phone in a way that would allow to flash the stock firmware. The SPF Tool kept giving me the "status-brom_cmd_send_da_fail (0xC0060003)" error. So, with my final effort I tried the steps that are explained in this thread https://xdaforums.com/redmi-note-8-pro/help/redmi-note-8-pro-bricked-t3976289/page4 (the last post on the page) . First I downloaded Miflash Pro from here https://androidfilehost.com/?fid=4349826312261688231 . It's in Italian, but don't worry, you just need to use a few functions within the program.

1. Once you have installed Miflash, open it.

2. Switch over to the 'Flash MTK' tab.

2. Load your firmware (I used this page to download mine https://c.mi.com/oc/miuidownload/detail?device=1900375 - European Version)

3. Choose Download Agent ( for example C:\Program Files (x86)\MiFlashPro\SP_Flash_Tool\MTK_AllInOne_DA_mt6785_mt6765.bin, your path coud be different)

4. Load scatter file (my example - C:\Users\your_username\Downloads\begoniav11030eea\images, it should be in the 'images' folder)

5. Click on 'Download'.

6. Connect your bricked phone

7. Now this step might work for you without pressing any buttons, as that was the case with me. But you could try pressing Volume - or Voulume + while connecting with the computer.

That's it. The flashing took about 5 minutes, but my phone was resurrected. BEAR IN MIND that before this hard brick happened, I did flash the files that were leaked a few weeks ago that permitted the use of SP Flash Tool without an authorised Mi account- the 'preloader' and 'lk' file. But I did flash an android 10 based firmware on top of it. As suggested by some senior members on this thread, by flashing an Android 10 ROM, I overwrote the 'preloader' and 'lk' files, therefore losing the option to flash with SP Flash Tool without an authorised account. But, the bottom line is, this method worked for me. So maybe it might work for you. And if you have a hard bricked Redmi Note 8 Pro, that doesn't have a previously flashed 'preloader' and 'lk' files, please, do try this method. If it works, then great, we just might have resolved some issues with hard bricking of this device.
