DTPro Redmi Note 9S/Pro Both IMEI Repair Successful

[rafik23]

HI
i have redmi note 9s ( now migred to note 9 pro india I love (mi calller and message apps) a few months ago I try to unlock Bootloader , ther operation was successful but i lost IMEI ,
i try to repair it.
after facing some constraint, to fix them both but still RSA problem which reboots the phone, so I did this as a next step:
flash with ENG rom in EDL mode (it costs between 15 and 22$ via teamviewer) and write QCN with 2nd IMEU then write 1st IMEIs but after this procedure flashing The normal ROM , it causes the problem rebooting phone , but in this case if the bootloader is locked ,there is only one solution left, that is hardware RSA disabled , it's to solder a resistor in parallel with the one mentioned on the illustration images for having 45 to 100 k ohms , have soldered 100K with 300Kohms , i get approx 75 Kohms , ok




the solution is perfectly work only when you reboot in fastboot or other in the boot this message is appears
but once reboot normaly it desapears

on this situation reboot normaly
the hardware version or board id is 1 but it requires RSA HW disable for working with Both IMEis

REMARK : for disabling the message in recovery (MIUI can't be installed on this device) when you enter in fastboot or edl mode , you must have Under 70 K example bettwen 56k and 40kohms , like I redo it now and no message appears when i start it in fastboot or another mode , i do it with soldering two 100k in parallel on the 300k factory resistor ( shown in first image in 1st post)
