[DAISY][OFFICIAL][FASTBOOT] v10.0.2.0.PDLMIFJ

V10.0.2.0.PDLMIFJ Pie Official Release by Xiaomi: Mod edit link removed.
GUIDE:
1. Make a backup.
2. Unlock Bootloader.
3. Enter in fastboot mode or EDL.
4. Use MiFlash.
Whats the reason for not using MiFlash?
And especially why relock the bootloader with the script, if anything goes wrong your device could be bricked!?

The packaging hierarchy is slightly different from that of an official because this is a repackaged that a user has made of 4PDA.
You can try if you think MiFlash will work. I only tested this via Flash.bat script on fastboot mode.
Working perfectly
in my use, these problems have been solved:
•SIM Card Issue, Solved
•No Disturb on camera, Solved
•Wi-Fi bug, Solved
I'm still analyzing the update..
Patched boot for this ROM https://drive.google.com/file/d/1dBX2dZV_wWgSip8d9lk0lrO_JHfxGdKU/view?usp=drivesdk

*If you don't want to relock bootloader, remove "fastboot oem lock" from "Flash.bat" and save.

Just a short question, will data be kept when not executing the OEM relock?
edit: Ok, i found out the the line "fastboot -w" will erase the user data. Anyone tried without this one?

Yes, just remove the two lines from flash.bat. Worked without problems here.

It is not necessary to delete data and reset the system!
You can upgrade to the newer version.
If you use Mi Flash Tool, select: flash_all_except_storage.bat
Or manually via fastboot:
Code:
adb reboot bootloader
fastboot flash devcfg devcfg.img
fastboot flash dsp dsp.img
fastboot flash modem modem.img
fastboot flash rpm rpm.img
fastboot flash tz tz.img
fastboot flash keymaster keymaster.img
fastboot flash cmnlib64 cmnlib64.img
fastboot flash cmnlib cmnlib.img
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash vendor vendor.img
fastboot flash mdtp mdtp.img
fastboot flash aboot aboot.img
fastboot flash sbl1 sbl1.img
[COLOR="DarkOrange"]fastboot boot patched_boot.img[/COLOR]
Open Magisk -> Install -> direct
Very nice! Thank you bro!
Worked without locking the bootloader

Make sure you have the latest fastboot driver's installed.
Did this work?
Hi, did you find a resolve?
I have the latest drivers and nothing seams to work. Tried 5 windows 10 computers with the same result. No partition.
It has to be something with fastboot or the boot image. Well, I guess your phone could be toasted as well. What happens with "fastboot flash boot boot.img" if you use the stock image?

Yes I can also install custom recovery but no ROM can boot up from custom recovery! If I keep device on fastboot mode it automatically turns off and turn on to fastboot mode.

If you can get those 4 files extracted to your pc, you will need to wipe your phone via fast boot, then flash all 4 of them files separately via fastboot and your phone should go back to normal.

If only I managed to access recovery mode your method would have worked. I tried flashing stock ROM recovery and Orange fox recovery but it always bootloops to fastboot way sooner than I can finish all of my steps. Same case when I tried to erase boot it bootloops faster than the process to be finished.
Can you please suggest me any method to stop bootloops atleast in fastboot mode?

have you done in extracting the *.img in the ofp file?
if yes then go to your cmd and type the command:
1. fastboot erase boot && fastboot erase dtbo && fastboot erase recovery && fastboot erase metadata && fastboot erase vbmeta && fastboot erase system && fastboot erase vendor && fastboot erase userdata && fastboot reboot-bootloader
the command was based from this thread : https://forum.xda-developers.com/t/realme-5-stuck-on-fastboot-mode.4096691/
then after issuing the previous command change the "erase" to "flash":
2. fastboot flash boot boot.img && fastboot flash dtbo dtbo.img &&...... (don't include the metadata group)
i just fixed mine today
