Securtiy Repair On SLA Based MTK Chip

[hitech care]

Hi Team


Is There Any Way To Repair Security On SLA Challenge Based Phones..


Actually I Am Having 1 Redmi 6A With Security Damaged I Need To Fix It Is There Any Way ...?


How This Problem Arise
======================
Redmi 6A Came Dead After ELS Found Emcp Issue Remove Old Emcp N Try To Connect On Socket Found Emmc Completely Dead Not Detecting...I Replace Emcp 32GB With 16GB Emcp Phone On But Unknown Baseband As I Write Another Phone Dump..After Flashing Baseband Ok But Security Damaged.


I Just Have Few Questions Can We Use OLD NV N Create New NV With My Phone Security (IMEI) Number...Or Can We Modify Firmware For BL Unlock..Or We Can Use SLA On CM2 For Direct Repair Security With It..

About Official BL Unlock:- It Will Won't Work With My Phone As I Don't Have Old Binded Account..If U Add New A/C U Have To Wait For 48 Hours To Unlock But Problem Is I Can't Login MI Account To Phone As It Dosen't Have Security So Not Login Any Account I Try Without Login Direct With Tool But Verification Fail .

Redmi 6A, unlike other plain MTK models, not contain OTP. But it contain modem, which check RSA signature of pair - UID(CHIP_ID) + IMEI/MEID + MAC's.

Enough to reflash device in most cases to back modem to live.
