Gentlemen, good day! Out of pure interest, I requested EDL firmware in the "SMT Download" mode, which essentially wipes out and replaces ALL sections on the phone. Yes, then I did not know about it ... In general, IMEI, MEID, MAC addresses - everything was worn out. Generated Macs, threw MEID and IMEI0 from the box - it doesn’t catch 4G and after a while it automatically finds towers, sometimes you need to choose manually. That’s okay, a kind person from this forum threw off .xqcn, band settings and calibration, at least approximate, I will return it through it. There are two questions in this situation:
1) I somehow need to get the IMEI of the second SIM slot, have ideas how it can be "calculated" from IMEI0 / SN / MEID? I looked at Google Dashboard, exported data about all Android devices on my account, IMSI shows both, and IMEI is only the first.
2) I really do not want to substitute the person who helped me and sent .xqcn, where can I find the most complete list of identifiers unique to each device? Well, or rather, information about which ones should definitely not coincide, for example, who knows what about GPSID?
P.S body OnePlus 5, SD835
UPD1: Forget, IMEI 1 and IMEI 2 are distinguished by the check sum and the 14th digit at the end.
UPD2: It turned out that on OnePlus 3 and above there is a special NVRAM cell that stores "encrypted IMEI". One APK-cabinet inside the firmware poured it into modemst, even when the usual IMEI record was zero, it certainly took me a couple of days. Who cares - NVRAM 2500, "NV FACTORY DATA 4 I". After I removed this from the .xqcn with the same xqcn-editor, I again reset the EFS to itself and flash it - everything became ok. (I thank the author of the utility and respect, I was surprised that this can be done through vba, also in Excel).
I only caught 3G, the second slot was with zero IMEI, now both of these problems are fixed, and as for me, the network began to cling faster.
