Modem Patched, Fixed LTE & Mobile data

[JigsawMobile]

I have an EA ROM on an ATT device, but we all faced on the A11 that after fixing the NT code, we are not able to use LTE and mobile data, but then we had the PDC tool where we loaded the .mbn.

Now on the A12 we don't have the ability to use PDC so I was forced to do something to get LTE & mobile data back and I made some changes to the modem .img where the problem was fixed.

Note: I read before that some people were not able to fix the fingerprint after croosflashing ROMs, now we can do it but by cross-modem images.

Current patched mods are for EA ROM A12 but there are one version for A11 if you do not want to use PDC tool.

We have three versions of the modems.

• V1 is with minimal changes only for EU bands (outside it wil work or not)
• V2 & V3 is with slightly bigger changes and can be used outsde EU,

in the previous modified versions, users had the problem that Netflix did not work on their A11, with V1.2 or Universal version where the mentioned problems have been fixed.

• V1.2 only for A11
• modem_Universal fully compatible with A10+ android but there are more changes than V3 modem

Note: it is always better to use a modem with fewer changes, this ensures that the updates are original and newer.

5G and VoLte working.

You can flash modems easily via Fastboot to A/B slots or you can flash via Qfill.
Flashing patched modem won"t bricked /bootlop your device.

so when you flash EU modifed modems all work but you do not have volte ?

sometimes when "cdma roaming option" option shows when NT code is not corect, do you have nt coe error ?

missing oprion in networks settings it not depend of modems.

I AM USING docomo v60 with EU firmware with docomo model....
Actually you sent me bootloader flashing file...
Can you flash both modified modem in your mobile and take backup from qfil share me....

 

[JigsawMobile]

Yes i can backup modems via qfill

try this first when you flash modifed modems via fastboot than backup via qfill and that modems try to open via qfil, and tell me will it open in the .7z.

well you can flash modifed images via qfill, qfill can flash and .img files

Ok now i can t unlock the bootloader now.
Do you have modified modem backup

Hello, should I flash the .gz file or do I need to extract it? If so, it looks like both images are 2kb bigger than the original ones.

 

[JigsawMobile]

You van flash via fastboot or via qfill, qfill can flash and .img.

Exttact from .gz you will get
Img

 

[lucasdessy]

I don't get any .img files, only files with no extension.
Tried to flash tem via qfil and fastboot, both methods give me a kernel crash.
Also, both qfil and fasboot warned me about those files not being the exact partition size which is 361.758.720 bytes, instead, they are 361.760.256 bytes.
I tried flashing them whole and also trimmed by deleting everything post 0x158FFF0, both made me kernel crash. Restoring the backed up modem partition gets me to boot again.

edit: I'm using 7zip to extract, maybe that's the issue?

To reatore do not extract only modem_a, need to be with extension .img

I will reupload in the rar compression

I would like to test the LG v60 Japanese version on a machine that has been cross-flexed to the Canadian version. Can I allow download access?

 

[andamiro00]

Thank you for the access.
It also doesn't work in the Japanese version -> Canadian version.

I had a question when I saw the text file in the compressed file.

Are the modified folders image\sdx55m, sdx55, modem_pr\so" and other att original modem files placed in the ea modem?

All changed files EA

I did not croosflash att and ea modems but i will test it method when i having att a12 original modem, i believe that we can get to work via croisflashiig original -> EA modems.

Note: if you want to try croisflash modem you need rooted device.

Why you using canadian rom version why not EA ?
