✅ Haan, kuch cases mein update ke baad BROM Mode access nahi hota.
❌ Lekin, har update par yeh apply nahi hota.

Possible Reasons:

• Secure Boot Protection enable ho chuka hai.
• MTK BootROM Exploit Patch apply ho gaya hai.
• Preloader lock ho gaya hai, jisse BROM Mode accessible nahi raha.

1. Preloader Security Update: Naye MTK updates preloader mode ko force enable kar dete hain, jisse direct BROM Mode access mushkil ho jata hai.
2. BootROM Exploit Patch: 2021 ke baad ke updates BROM exploits ko patch kar dete hain, jis se Auth Bypass tools kaam nahi karte.
3. DA File Restrictions: Update ke baad custom DA file kaam nahi karti; sirf official secure DA file use hoti hai.
4. SP Flash Tool Restrictions: Flashing ke dauran scatter file aur DA file check karna zaroori ho jata hai.

Example: Xiaomi, Realme, Oppo, Vivo, aur Nokia ke naye models mein update ke baad BROM Mode disable ho sakta hai.

A. Test Point Method

1. Phone ka back cover open karein aur Test Point (e.g., CLK) locate karein.
2. Test Point ko ground se short karein using a metal tweezer ya copper wire.
3. USB cable connect karein; device BROM Mode mein enter ho sakta hai.

B. Custom Preloader Use

Agar official preloader lock ho jaye, to custom preloader flash karke BROM Mode enable kiya ja sakta hai.

C. Downgrade Firmware

Agar update ne BROM Mode disable kar diya, to old firmware flash karke device ko downgrade kiya ja sakta hai (SP Flash Tool ya Miracle Box se).

1. OTA Update Disable Karein: Agar BROM Mode ka access chahiye, to Developer Mode mein ja kar Auto System Update disable kar dein.
2. Firmware Backup: Update se pehle MTK Preloader aur BootROM ka backup bana lein.
3. Custom Bootloader Unlock: Kuch models mein custom DA file ya Auth Bypass Tool se bootloader unlock kiya ja sakta hai.

Agar aap flashing, IMEI repair, ya FRP removal ke liye BROM Mode ka access chahte hain, to update na karna behtar hai. Lekin agar phone ko latest security ke saath safe rakhna hai, to update karna zaroori hai.

Agar aapke paas koi specific model hai jisme update ke baad BROM Mode access nahi ho raha, to uska best solution nikalne ke liye hamse rabta karein.
