broken IMEI ok K430dse

Hi,
I write wrong firmware and bricked phone, then i restore old one but i got empty imei number.
I read about MauiMeta and try to recover Imei number, but i don't have proper modem file (file BPLGU.....). I try with file from k430dsy (http://forum.xda-developers.com/lg-k10/development/lg-k10-k430dsy-original-modem-file-t3481543), but it didn't match. Is there possible to extract it from oryginal KDZ file? Maybe someone have this file.

If you know your original imei nr. you can download your firmware with lg mobile support tool.
What apout lg bridge update error recovery?
Or in case you have your original firmware you should search for mobileuncle tool, there is an imei repair thing for MTK devices.

I mentiuon several times on whatsapp group to make a backup of the ID's partitions before changing firmware.
To restore it now you will need a box now.

[REQUEST] Anyone willing to extract and share qcn / xqcn backup ?

Hi,
I recently tried to flash qcn on my OnePlus 7T and it seems that I lost efs data (some sensors aren't working now).
To extract qcn or xqcn file you need to enable usb diagnostic port (in phone app dial *#801# and click the second and fourth buttons).
Doing so will make your phone detectable in Qualcomm softwares.
To extract qcn, use QFIL and click Tools>QCN Backup/Restore. In the field "QCN file path" write the path to the directory you want to save the backup, and also write the name of the file that will be created. Then click Backup QCN.
To extract xqcn, use QPST Software Download, and go to the Backup tab. Click Browse to select the destination for the xqcn backup, and set a name to the backup that will be created. Then click start.
Doing this process is quick and should take approximately 5 minutes if you already have the QPST software.
In case you need it, I have the installer from Qualcomm for QPST 2.7.480 :
http://www.mediafire.com/file/nm0zlac003tn41j/qualcomm_qpst_setup_2.7.480.zip/file
Also you have to know that your IMEI will be visible in these backups, and you should remove them using an hex editor to replace it with some random numbers or zeros before sharing it with me or anyone.
If you need informations on how to find your IMEI in your qcn or xqcn backup using an hex editor, I will explain it in this thread too.
Thank you

Are you saying with these same methods you lost efs data or you did a mistake while flashing ?

Thanks @egekonuk for your reply.
In fact I was trying to flash international rom version on my TMobile Oneplus 7T by editing MSM download tool (using x64dbg which is a software sharing many functionalities with IDA Pro).
I did not managed to flash international but yes, I lost efs in the process.

Just curious why you didn't do the other posted method to go from TMO to international? I did the other method and it worked out just fine. Of course I don't know if that very friendly person is still doing unlocks or not.
Is there a difference between the QCN and XQCN between ROMs?

@amcferrin90 yes I didn't mentioned that but it's because my device was not SIM unlocked by T-Mobile. I bought it on ebay and I was not aware it was not paid off, and seller refused a return.
If I was SIM unlocked, I'd be able to unlock the bootloader and flash the international rom using fastboot.
I did not understand what you meant about qcn, xqcn and roms.
To me, qcn and xqcn are different because xqcn backups are larger than qcn ones.
I think xqcn contains some efs data, but I'm not sure about this.
Would you be ok to make a xqcn backup and share it with me?
Thanks

I also need a backup of QCN.(please)

you can change the IMEI as you like using Maui META but now the NV data file itself is corrupted so the phone won't boot

So i need a valid NV Data file to be able to fix the IMEI

I'll upload mine (but modified IMEI), but which file?
is it the nvdata folder inside /mnt/vendor?

i guess so

NV Data NV Ram

I don't think it's correct, the nvdata folder only consist of GPS ID, BT MAC, WiFi MAC files.
The rest is a bunch of calibration files for sensors.
I'll try extracting using Maui.

Sorry bro, unable to extract it using Maui as well.....

hey do yo find any way to fix it my also same as you. If you fix than please tell me how?? It will be really helpfull. @MohamedYousri and @Crescendo Xenomorph or if anyone can please tell me how can I fix it.

Hey All,
My Phone's Begoniain [ 8/128 ] .
I tried flashing a custom rom on my phone ended up with the bootloop.
So, I tried flashing the stock rom and my IMEI number got deleted.
I used MAUI IMEI Tool to restore the IMEI. Later I realized that the NV Data got deleted ( NV Data is Corrupted ).
Now I'm unable to install MIUI and also not able to see any network related information ( IMEI No, MAC, Sim, Wifi, Bluetooth, etc., ).
I searched all sites, No results regarding [ Mediatek Helio G90T MT6785V ].
Can anyone advice me on this.

how much priced you for this.?

primero debes resetear el efs (con UMT o por TWRP) para dejar los imieis en "0", luego para repararlos pasan el firmware y ponen un nuevo imei o restauran el que tenian y listo

MOD EDIT: English Translation Below
First you must reset the efs (with UMT or by TWRP) to leave the imieis in "0", then to repair them pass the firmware and put a new imei or restore the one they had and that's it

did you guys resolve it ?
i may have an idea

Any fix

do you guys even search before asking?
First, do a TWRP backup, all partitions including efs & modem.
Open the root explorer app, open the efs folder, delete the files named nv_data.bin
, nv_data.bin.md5 & the folder called imei. Then open twrp, wipe all partitions. Flash the latest firmware with Odin.

That solution work???

This should give you a good idea of how to re-write the partitions!

Sorry, maybe I'm referring to the wrong place, but I did not find another post related to qfill. My question is: Is it possible to replace the APN settings file through QFILL and if so, what is the name of this file? I have lg v50 thanq 5g. Thank you!

APN settings can be modified under your network settings.You won't need Qfil or anything for that?What are you trying to accomplish?
