Liste, updating to 11.0.350 solved communication issue of many users !!!

May be it resets proper QCN partition or whatever. Anyway there is no point in staying with earlier ROW version they are crap !

You didn't understand, I've erased my QCN file by mistake, and I've asked on this forum topic for a QCN file, the only version that x-geo's QCN file works is on default ROW version, if i upgrade I lose the signal.
It's Not with maybe, or perhaps, it's for sure 'cuz I've tired many options. That's why I ask here for any guidance.
Proof:


Any technical suggestions are welcomed :)
Thank you,

yes, in the lenovo z6 pro telegram, shared a generic QCN who fixes the call problem, i was using that QCN file, but when i updated to 0.350 the signal failed and didnt come back, i have the original backup of the QCN file, i did put the imeis and restore it, the problem was the generic QCN, @kjawenm, please can you send me via pm the imeis, the bt mac address and the wifi mac address (both from the box.. the generic QCN has anothers), and i send a QCN of a Z6 pro with that values and ready to restore, before the restore, i recommend flash the global firmware via QFIL and close the bootloader

Check posts #9 #10 #11 in this forum topic, it's all there for stock ROW rom.
Long story short:
1 flash row stock rom(QFIL)
2 flash alexeei's recovery(in case you have bootloop.)
3 boot system dial : *#*#33284#*#* and enable diag mde.
4 with QPST config->software download-> restore-> restore QCN file from post #9 with YOUR IMEIS !!
5 reboot to bootloader and with fastboot enter commands from post #11 (with persist and NON-HLOS from stock rom)(change NON-HLOS.bin to NON-HLOS.img)

I leave you mine with a random imei, change it to yours and tell me if works (change the extension to QCN)

hiya. new to this place... is there any way you could share the file any other way ? when clicked on the file, it opens the file and browser can't read any of it properly. when tried copy pasting what it brought up, file got twice heavy, compared to the original posted. tried QR code and to no avail, again.

When I dial *#*#33284#*#* to enable diag mode as istructed, a message on screen appears: "set sys.usb.qxdm_on to 1" and the diag mode remains unactivated. What should I do in this case? Wi-Fi is working since I runned "Fastboot erase persist" and "Fastboot flash persist persist.img" in prompt inside fastboot mode. If I just ignore it and try to execute "Fastboot erase Modem" and "Fastboot flash Modem non-hlos.img" returns command FAILED (remote: No such partition.)
UPDATE: Resolved. after enter in diag mode, upload a 'blank' QCN file to the phone and then the fixed QCN. Worked for me.

Anyone have idea what it is?

    hello valdo, as you managed to restore the imeis, could you please help me restore them. thank you

    Hello, you fixed the problem? i lost the imeis but restore it with a QCN Backup, but i dont have signal... thanks for your help

    i find the fix: thanks to tommyb2 in Lenovo english forum for the tip

    As it looks like you damaged your qcn you need a new one !

    is your WiFi working ??

    if not try this first !

    enter Fastboot

    then

    Fastboot erase persist

    Fastboot flash persist persist.img

    (your WiFi should be back)

    try

    Fastboot erase Modem
    then
    Fastboot flash Modem non-hlos.img
    After that Fastboot reboot !

    maybe also your imei ?!

    if not get a QCN, enter Diag mode (see page 12-13)

    and replace it with a new one !

    with an imei editor you can put in your imei



    The Files you found in your current ROM !

    Non-hlos.bin has to be renamed to.img

    Thank you for the qcn file, it did help but not nearly enough.





    Any other ideas on how to fix this ? I'm giving up on this 'cuz it seems so ...... chinese .
    Edit1: Do I need to change MEID or any other unique ids ?

    mied, is part of the imei... not neccesary to modify...

    now, do this:
    enter Fastboot
    then
    Fastboot erase persist
    Fastboot flash persist persist.img
    Fastboot erase Modem
    Fastboot flash Modem non-hlos.img
    Fastboot reboot

    I'm sorry it took so long to respond but I was on a trip.
    It works, I've got my signal back, but sometimes when I start a conversation the other person hears bad, like when you speak underwater. It doesn't happen when I put my headphones(not yet anyway),
    but I guess this will be solved in the future updates.
    Thank you very much :) :victory: :good:
