How to unlock 4xCA at EM7565?

[shvedv.egr]

Hello there
At stock 00028874 file there is a lot of 4x
CA
https://smartphonecombo.it/uecapabilityparser/view?id=638ee9c951
But i have tested some 4xCA at my region and in UeCap there is only 3xCA Smartphone Combo - Sierra EM7565 25002
And for me works only 3xCA combos at all providers.
Last time i’ve tested EM7565 with 3-7C-20 aggragation, but works only 3-7C (3xCA limit)
At test i change 00028874 and write to in ontly 20-7C-3 combo, but in UeCap still only 3xCA combos:
Smartphone Combo - Sierra EM7565 25002
I know that EM7565 is cat 12 = 600 mpbs limit, but X16 modem can aggregate 4 carriers.
I’ve cheched lte_category, enable/disable_cap_ies files at EFS but no luck with that (there is no files with this name)
May be someone know how to unlock 4xCA at EM7565?
Thanks for answer

Hi @shvedv.egr

Sorry, I took some time to respond. If you look at the modem’s specification document, we state that we support 3CC in DL. The modem supports CA_3A-7C, CA_3A-20A etc. 4CC in DL is not supported. Please go by what we provide in the modem’s document. The MDM9x50 chipset might support more combinations than what is offered by the EM75 modem.

If you want a higher performance LTE modem, please check out the EM7690 modem. Thanks.

[anon56110884]

BTW, your LTECA looks different from mine with latest 01.14.xx.xx FW, https://source.sierrawireless.com/resources/airprime/minicard/75xx/airprime-em_mc75xx-approved-fw-packages

[shvedv.egr]

After A LOT of downgrades/upgrades/wipes i still have same combos at LTECA?
(BTW, after delete 00028874 file and re-flashing FW there is recovering same combos with same 00028874 file)
