Amazing ROM, probably the best Lineage build I’ve seen. Unfortunately it doesn’t work for T-mobile. Looks like the radio doesn’t support 4G on this ROM, was only able to get H+ and even then it dies after a reboot. Seems to be missing the critical “LTE/WCDMA/GSM auto (PRL)” entry, can verify by bringing up the ##4636## phone test options.
I was on Nougat firmware, assumed that was needed given this is a Nougat OS release. If it requires the Oreo firmware, would be nice to know since the instructions are fairly vague.
totally wrong, I have used t-mobile for around one year on 2 eOSdevices with fill 4G / KTE+
It seems more an issue of your firmware. What Android version do you running now and what version was on the device BEFORE eOS ?
Which t-mobile, europe or usa?
Have to agree, it is not a ROM thing. More of a device limitation I’d think. The device itself (or model/variant) must support the bands used by a chosen carrier. The ROM is (mostly?) carrier agnostic.
I am on T-Mobile in the U.S. with /e/ on two devices. No problems with 4G/LTE here.
If device is okay then…
If whatever previous ROM or firmware you had before was working fine then maybe something went weird when switching over to /e/.
Even when playing/testing around I’ll go from perfectly working to messed up networking.
Provide all the info harvey186 asked for to get a better idea of what may have happened.
Let me clarify… I’m using a HTC 10 unlocked version. Was on Lineage 17.1 (Oreo firmware) but the battery life was abysmal. So I downgraded to Nougat firmware (by flashing the old radio, deleting the persist parition, then RUU with the last known Nougat version “RUU_PERFUME_WL_N70_SENSE80GP_VZW_MR_NA_Gen_Unlock_2.51.617.32.exe”. After that finished, I was running that for a week with this version without any issues. I then flashed the e ROM and thats when I had massive issues getting 4G. No other firmware was flashed between the official HTC 10 RUU and e – I just used TWRP to format the system partitions per instructions and installed e.
Under settings->network settings (or whatever the equivalent in Lineage is), the network mode shows the right one “GSM / WCDMA / LTE auto” or something similar but the problem is the actual radio does not have that setting in the phone test options (when dialing ##4636##"). The only data signal I was able to get was H+ and that was with some combination that included UTMS.
After that happened, I RUU’ed back the Nougat version above and was able to get the data back to full 4G/LTE.
I didn’t have time to tinker or really look into it, but it could be something as simple as missing entries in the build.prop file. See https://www.internauta37.altervista.org/en/patch-fully-enable-gsm-cdma-global-phones-android
For the others saying Tmobile works fine, are you also using an HTC 10 or is it a different model/phone? If you are on HTC10, are you using Oreo or Nougat firmware?
