Any ARB4 fastboot rom: my phone is china variant so I use this rom: "lavender_images_V10.3.1.0.PFGCNXM_20190403.0000.00_9.0_cn_a2cbd6207b"

1. Download and install QPST.
2. Download and Extract fastboot rom folder. You can use any latest fastboot rom. If you have Global variant use Global fastboot rom and if China variant use China fastboot rom to prevent being stucked on recovery (Miui version can't be installed in this device).
3. Download patched prog_emmc_firehose_Sdm660_ddr.mbn and copy inside fastboot rom images folder.
4. Remove back cover, remove battery. While connecting 2 Test-Point, plug in USB cable into PC

Hi!

This method helped me recover my Redmi Note 7 from bootloop. Thank you very much!!!

My situation was the following:
I flashed Global Rom onto phone Chinese version and accidentally locked the bootloader. After that, only opening the back cover and short-circuiting Test-Point contacts with battery unplugged helped get the COM 9008 port in Windows. Next QFIL flashed Chinese ROM into eMMC without problem, and the phone could boot into UI again!

I followed the steps precisely and confirm it works.

Also, while opening the back cover I realised that my phone had been opened by seller before me! The Test-Points contacts had distinctive dents from tweezers! I bought the phone from AliExpress from 'Xiaomi Retail Store' seller as a brand new one, but it turned out to be the contrary :|

Wish you successful restoring of your phones , mates!

• Be more careful with what you flash. Always check and heed warnings.
• Always select clean. Never keep data or clean and lock. That is how I bricked.
• There are two bootloaders in a phone: Primary Bootloader and Emergency Bootloader
• All Qualcomm devices have this special mode (EDL) to directly flash a ROM to the EMMRC memory. This is done through the sahara protocol
• Qualcomm has developed a special framework called Firehose programmer for creating partition tables and other low level operations.
• Xiaomi locked down this EDL mode and made updates through it only available from authorised accounts due to malware and blah blah blah. ("Only noop and sig can be received before...")
• ChocoML has provided us with a Firehose programmer file that bypasses these restrictions. However, to my knowledge, it ONLY works with the Chinese ROM and therefore, with devices that support that rom.
• THEORICALLY, you can keep user data even after all these low level operations: http://en.miui.com/thread-235865-1-1.html (Scroll to blue text).
• Every device/processor has a different Firehose programmer file. For other devices, look for the appropiate Firehose file.
• Redmi Note 7 Pro (India) has a different chipset (violet). Do not attempt to use this guide.
• Make sure you've got a fine USB cable with data transfer properties. DO NOT EVEN THINK OF BREATHING NEARBY THIS CABLE WHEN FLASHING. Lest you get a permabrick.
• "Receiving hello packet" Error: Reboot the PC and phone to Solve it.
• You cannot dawdle when flashing using the QFIL. As soon as you establish a connection to the 9008 port, click on download. Lest you get a Sahara Protocol Error.
• Useful tip: Do not connect the USB cable last to your device. Connect it first to the device and last to the computer. It's easier to short the testpoints this way.
• Heat guns are hard to regulate. Hot plates with temperature displays are recommended to avoid display damage.
• Have a great deal of patience. It's touch and go with these things. Do not try to rush.
• Unplugging the battery is compulsory. You do not have to physically remove it: just remove the ribbon cable that connects it to the MB.
• Make sure you are flashing a Fastboot rom and not a recovery one.
• After I flashed the Chinese rom, the phone rebooted yet again to recovery. Reboot and check if it works. If not, wipe data and reboot.
• Exercise circumspection when updating or changing ROMS. Be sure not to trigger the Anti Rollback, which has a similar upshot as flashing the incorrect rom version
• You can no longer apply for an authorised Mi account. Thread 404'd
• Do not pay extremely high fees for unlocking online. Try this tutorial first. Then service center. Only then pay.
• Do not lose hope. This is the most important point of the list! It took a while and it certainly was a surly experience but you can pull it off. (Unless you've got the global version; may God be with you in that case)
