I did something rather dumb in qpst NV RAM editor without first making a proper backup, and now I am stuck without any service. If anyone reading this has a global bands edition (preferably the 6/128 gb version, but I think any with global bands will do), and is willing to help me out a bit here, could you follow the instructions it the link below for taking a modem settings backup and post the file?

REMEMBER: make sure you wipe BOTH of your IMEI numbers from the resulting file before posting them. You really don't want to share that info online because that's your phone's unique identity You probably can do this by searching for your IMEI converted into hexadecimal (using the converter in the link), and replacing it with something benign of the same length like 111111111111111 for the first one and 222222222222222 (hexadecimal equivalents of the same length) for the second one.

Instruction link: androidbrick.com/ultimate-guide-qualcomm-snapdragon-xiaomi-mi5-imei-and-baseband-repair-fix/

QPST Link (use this one instead of the one in the guide): androidbrick.com/download/download-latest-qualcomm-flasher-qfil-qpst-2-7-460/

Thanks!

Sorry to say, it won't work. Even if it's the original QCN from your device, it won't work. If you have a backup of YOUR modemst1 and modemst2 partitions, or a backup of your fsg partition, you can restore those and it will work. If you restore someone else's, it won't work.

This stuff used to work with older phones, but no longer does with Mix 2S.

Sorry for the bad news.

Hi, I also have a Mi MIX 2S and I am starting to wonder whether the change of model numbers (M1803D5XA -> M1803D5XE after flashing Global over Chinese ROM) will indeed Change the phone's connectivitiy capabilites (supported LTE bands, WWAN protocols and standards) for my 8 GB/256GB Mi MIX 2S M1803D5XA (now M1803D5XE). IIRC the 8 GB/256GB Mi MIX 2S "Privilege Edition" was marketed as the "global model" in China, so there is should be no unlocking of additional LTE bands etc. if I flash a Global ROM over a Chinese ROM ...
Thanks!
Lars

Are you sure it saves a QCN which works when flashed? Normal tools to do this like qpst don't work for this. Are you sure that it isn't just backup of the modemst1, modemst2, fsg partitions it takes?

I did something rather dumb in qpst NV RAM editor without first making a proper backup, and now I am stuck without any service. If anyone reading this has a global bands edition (preferably the 6/128 gb version, but I think any with global bands will do), and is willing to help me out a bit here, could you follow the instructions it the link below for taking a modem settings backup and post the file?

REMEMBER: make sure you wipe BOTH of your IMEI numbers from the resulting file before posting them. You really don't want to share that info online because that's your phone's unique identity You probably can do this by searching for your IMEI converted into hexadecimal (using the converter in the link), and replacing it with something benign of the same length like 111111111111111 for the first one and 222222222222222 (hexadecimal equivalents of the same length) for the second one.

Did you manage to fix it? It just happened to me too.. How can I resolve this thing?

I did something wrong too few days ago that cause my phone modem to kind of like restarting.. this cause the phone disconnecting every few seconds in qpst and restoring xqcn become difficult.. the trick is to restore it again and again when it failed until it is restored successfully.. you need to start restore as soon as you see the phone online because it will disconnected in few seconds so time is essence.. if your phone modem become offline after few time failed restore just restart your phone and do it again.. it may take few times before successfully restore complete xqcn.. after successfully restore dont disconnect yet.. please change the setting you change you made before its broken to the original setting and restart your phone..
