SPD (Spreadtrum) chipset wale devices ko flash karne ke liye ek “Loader Key” chahiye hoti hai, jo boot process ko unlock karti hai aur device ko flashing tools ke saath connect karti hai.

SPD Loader Key ka basic kaam boot security ko temporarily bypass karna hota hai, taake device flashing ya unlocking ke liye ready ho sake.

Iska kaam yeh hai:
✅ Flash tool aur SPD device ka connection establish karta hai.
✅ Unauthorized flashing aur modifications allow karta hai.
✅ FRP, screen lock, aur dead boot recovery ke liye zaroori hota hai.
✅ Diag Mode, EDL Mode ya Fastboot se bhi related hota hai.

1️⃣ Auto Loader Key (Built-in)

🔹 Latest SPD flashing tools (jaise Miracle Box, CM2, Unlock Tool) mein auto-detect loader keys hoti hain.
🔹 Yeh tool device ka chipset identify karta hai aur correct loader key apply karta hai.

Faida:
✅ Automatic aur secure method hai.
✅ Kisi manual key ki zaroorat nahi padti.
✅ Multiple SPD models support karta hai.

2️⃣ Manual Loader Key (Custom)

🔹 Agar Auto Loader Key kaam na kare, to aap custom loader key manually select kar sakte hain.
🔹 Har SPD chipset (SC7731, SC9832E, SC9863A) ka alag loader key hota hai.

Faida:
✅ Agar auto method fail ho jaye to manual method kaam karta hai.
✅ Unsupported models ko bhi flash kar sakta hai.
✅ Dead boot recovery ke liye helpful hai.

2. Device ko SPD mode mein connect karein (Vol Down + Connect).
3. Agar auto loader key fail ho jaye, to manual loader file select karein.
4. Flashing ya FRP remove ka process start karein.
5. Process complete hone ke baad device restart karein.

• ❌ Galat loader key use karne se device dead ho sakta hai.
• ❌ Unknown source se loader file na lein, kyunki virus ho sakta hai.
• ❌ Har SPD chipset ke liye alag loader key hoti hai, sahi select karein.
