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 ). Before we begin i must add, changing a working imei of your phone is ILLEGAL. “International Mobile Station Equipment Identity” is your phone’s unique identity. The IMEI number is used by a Linkleri görmek için lütfen Üye Olun veya Giriş yapın! network to identify valid devices and therefore can be used for stopping a stolen phone from accessing that network. So if you wanna change that number you are probably a thief or you are living in Turkey If you flash a wrong firmware/rom to your phone, for example 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”. This is becouse your orginal modem configuration has been written over with wrong one. This can be fixed while flashing the right rom back again if you are lucky (if original data is not corrupt). 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. I’ve seen many cases about lost or null imei’s after stock OTA updates, Samsung owners will hear me well i know. For this operation we will use the program called QPST from Qualcomm himself, its a service grade factory software to handle/change/fix many configuration options on Qualcomm’s. Other then QPST we will need (+ for editing imei) : 1. Linkleri görmek için lütfen Üye Olun veya Giriş yapın! (2.7.430) 2. Linkleri görmek için lütfen Üye Olun veya Giriş yapın! (or any other hex editor you like) 3. Linkleri görmek için lütfen Üye Olun veya Giriş yapın! 4. Linkleri görmek için lütfen Üye Olun veya Giriş yapın! 5. Linkleri görmek için lütfen Üye Olun veya Giriş yapın! (2016, universal) 6. Your phone model’s USB drivers (in some cases) First Step : We need to open our Snapdragon’s so called “Diag/nostics Port” before we can do anything. To do that; some phones have just a hidden code to open that port, some phones needed to be forced from adb after rooted and some phones has that port open by default (and some you can open from developer opitions). As you can see we have many options here. I will give some examples (mostly used), others you can ask me in comments. Our working example will be Xiaomi’s Snapdragon 820 flagship Mi5. You can open that diag port with dialing *#*#7177171#*#*, a message will come up saying “Diag USB port enable”. If you installed your drivers properly you see the ports under device manager like this : Now open QPST Configuration browsing “C:\Program Files (x86)\Qualcomm\QPST\bin\QPSTConfig.exe” and you will see that our needed diag port has been added automatically.
