Your phone model’s USB drivers (in some cases)

Qualcomm QPST Diag drivers (2017, universal)Ħ. Mitac Hexdecimal Editor (or any other hex editor you like)ĥ. Other then QPST we will need (+ for editing imei) :Ģ.

I’ve seen many cases about lost or null imei’s after stock OTA updates, Samsung owners will hear me well i know.įor this operation we will use the program called QPST from Qualcomm himself, it’s a service grade factory software to handle/change/fix many configuration options on Qualcomm’s. So our first goal should be to backup that important data before we upgrade even to stock rom, because even the biggest phone makers are still amateurs when its about Qualcomm’s data/partition structure. This can be fixed while flashing the right rom back again if you are lucky (if original data is not corrupt). This is because your original modem configuration has been written over with the wrong one. If you flash a wrong firmware/rom to your phone, for example, the same model but sold in different countries with different modem configurations, your baseband can become “unknown” and your imei will probably be “null” or “invalid”. So if you wanna change that number you are probably a thief or you are living in Turkey 🙂 “International Mobile Station Equipment Identity” is your phone’s unique identity. The IMEI number is used by a GSM network to identify valid devices and therefore can be used for stopping a stolen phone from accessing that network. Today we will learn how to fix/repair our beloved Snapdragon’s lost or corrupt imei’s and as a bonus, we will also learn to fix our “unknown” or again, corrupt Baseband’s ( modem configuration ).īefore we begin i must add, changing a working imei of your phone is ILLEGAL. Update : For Xiaomi Mi6 please use latest QPST
