Modem Patched, Fix LTE & Mobile data after croosflash

[JigsawMobile]

I also tryed to your modem image but after flashing your universal modem it shows your phone is permanently locked and can not be unlocked

go phone info and see if IMEI there ot its 0.

Use universal modem only when other like V1-v3 does not work

Come to telegram group about problem with imei or make new your thread, this thread only for modem

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.

EFS tool, it using in test diag mode, phone must be in android.

we cant just extract partitions its encrypted

Well that's a freaking pitty. I stiil haven't found a way to put the custom rom into diag mode yet so I can't use EFS Explorer tool. But the good news is it may not be necessary. As I already mentioned, when I first flashed your modem.img v3 I got modestly better dl speeds. Now its somehow changed. Maybe tmob was screwing around with their equipment in the area or something else was influencing the network speed, but suddenly I got this.

This is with LTE only, no 5g connection was ever made. This is by far the fastest DL SPEED I've ever seen on this phone. The qcom x55 modem on this phone can absolutely run.

glad you are able to solve your problem that's good speed also you can try with V2 i think it will work for you too.

At this point, unless you just need to know whether it'll work or not, I'm completely satisfied. I've never even seen 5g get to that speed, at least not in my area.

BTW, in a nutshell, what mods are you making to the modem img. Specifically, what changes to V3?

You can unpack each modem separately and you can see what changes have been made. There are some files from A10 because a10 is much more flexible and less restrictive compared to newer firmware.

Which country cartier do you using, why universal modem, why not v1 or v2

Which country cartier do you using, why universal modem, why not v1 or v2

I use a Nigerian carrier called MTN Nigeria.
I ask about the universal modem because V1 did not work for me, produces no network reception. V2 and V3 works, but I can not use my mobile data. I can see 4g , my network settings is open. Infact, like I mentioned , I can use some apps like whatsapp and Telegram but I can not use my browsers, Google playstore or any of my main apps.
My fingerprint doesn't work but I really do not mind.

I just need my mobile data working again

Guys, I finally figured this thing out! So I just had to search for my network and select it, even tho it was registered automatically, but damn! I went through hell just to figure this out!

Now I can use my web browsers , playstore and every other application.

[zigiz1]

Bought phone - unlocked carrier LM-V600TM, ver. V600TM30d., made backups by QFIL. After that I unlocked bootloader, crosflashed POC V600EA30c_00_0616 kdz. Made changes in ftm - implemented OPEN_EU NT code, restored phone serial No. by HxD as administrator from original ftm backup and loaded by QFIL to phone. I live in EU Lithuania, and modem didn't work in LTE mode. Flashed to slot_a and slot_b modem from thread A12 v1 by QFIL. Modem didn't work in LTE mode. Flashed to slot_a and slot_b original modems from TMobile by QFIL. Modem worked in LTE mode, until restarted phone. After restart stopped. Flashed to slot_a modem from thread A12 v3 by QFIL. On slot_b leaved original modem from TMobile. Now LTE mode works, can access Hidden menu. Seems fingerprint works, but I don't use it. Phone working slot for operational system is slot_a. Issue: - can't connect to LG SmartWorld by own LG account, because it's ejected by app - got message - in my country LG SmartWorld don't supplied. But can connect to LG SmartWorld by device account.
