Hi everyone,
I have the LG Optimus L90 D415 from T-mobile. I'm in Europe using a different carrier and I can only connect to 2G (EDGE). Following the instructions I found, I configured properly the APN and tried to change the radio to "Euro band" from the *#*#4636#*#* menu but when I press the option "Select radio band" I don't have any options to choose, just the title "Set GSM/UMTS band".
I didn't find any custom ROM to check if it changes. Can you please help me?
Thank you in advance.
It may be under the menu found via 3845#*415# ,
Theres radio settings to enable band 2100. Not sure if it will work without a new anntena in your phone. Tmobile US do not use full 2100 band but a cdma subset.
Failing that i think your wasting your time with roms. Try updating the firmware for your anntena. Perhaps the firmware from the 405 model but update firmeware with cation
Did u get it working ?

After enabled is it possible disable it?
hi
Did it work?
The T-Mobile version of the phone does not support UMTS (3g) on band 1 for the 2100 Mhz frequency as many European and other countries use, so that's most likely why there aren't any options, because nothing you could change would make a difference.
Help
Any solution for enabling WCDMA 2100 band 1 on LG-D415 ?
Issue: using 3 in the UK and they are running LTE Bands 3 and 20. I am looking at my wife's phone next to mine and she is camped on 3's Band 20. I am using an N900t and it won't allow me to enable those bands, even when forcing to either of them in the service mode. I'm running the OB6 firmware, CSC, and bootloader. The ROM is an Alliance TW 5.0 with TWRP as my recovery. I've also enabled CA as well as LTE Rev 10 to no avail.
I don't know much about how this OS works, but I am thinking that the baseband is reading the CSC and disabling the OCONUS LTE Bands, which is why they won't enable in the service mode. There is no other CSC for that firmware on sammobile, and I've read that flashing a mismatched CSC can cause incompatibility issues.
Thoughts?
I definitely posted this in the tmo note 3 form, not sure how it got here...
The phone has a hidden menu if you type *#546368#*930# in the dialer.
Does anyone have experience with activating VoltE and switching LTE bands.
I live in Denmark and my carrier supports voltE but it is not activated and I don't know how to activate it on this phone.
Try flashing the India DS firmware on it, which allows VoLTE, at least with India carriers.
Does anyone on HK or India software version have access to IMS settings in the Field test in the hidden menu?
I don't have access to IMS settings in Denmark on the HK software version.

Here's India firmware if you want to flash it via dev patched LGUP.
[H930DS][STOCK][OREO]LG V30+ INDIA H930DS H930DS20b_00_OPEN_ESA_DS_OP_0530.kdz
You can always flash back to HK if it doesn't have what you want.
Hi All, I have unlock ATT version, then switch to T mobile service (flash T mobile firmware). Now I switch to Sprint firmware. HOwever My ATT ver didn't have the band 25 and 26. Only have band 41. Sprint needs all 3 for better connection. Is there away to unlock 25 and 26 band?
Unlock S9 plus vers and other have all bands

The G965U and G965U1 are identical hardware wise and all support the same bands. What differentiates the G965U from the G965U1 is the that the G965U1 has the unlocked firmware (non carrier branded if that term makes more sense).
The only thing that differentiates one G965U from another G965U is the firmware. The firmware determines what bands are available as well as custom carrier settings/apps/configurations that is installed. For example if you properly flash the firmware for the Sprint G965U onto the AT&T G965U then it will have all the bands (and sprint customization/bloat) that the Sprint G965U version has.
To give you an example I have the sprint version, flashed it to the unlocked firmware, flashed to AT&T firmware and then finally to T-mobile. I didn't flash it in that order, that is just the different kinds of firmwares I have had on that phone.
Across the different firmware versions all necessary and needed bands were active and working just fine.

Yes, i put in Sprint Sim on the phone then the phone auto removed the Tmobile apps and installed bunch of Sprint apps. I checked the specs for ATT ver and only see band 41 avail online. After Sprint firmware installed, I check again *#0011# and only see band 41. I was too assumed everything should be identical both S9 plus U or U1 but there must me something got block by ATT and carrier firmwares still can't unlock it.

Did you flash the sprint firmware onto the at&t phone you have or did you just insert the sim card and let the phone apply the settings for the sim card?
If you did the latter (specifically just changing the sim card) this doesn't give you any of the carrier specific tweaks/customizations that can be found on the carrier firmware. For thse tweaks/customizations you need to flash the firmware for the carrier branded phone. So your better connection desire will most likely be a sprint firmware specific thing and not found on the at&t firmware.
Also looking up what the at&t branded phone supports and the sprint branded phone supports won't help much. It will only tell you what the two phones are configured to do for the carrier the phone is branded for. Those specs It do not tell you what the hardware can do (or that the hardware is the same whether it be the unlocked version from Samsung, the sprint branded one you buy from sprint or the at&t branded one purchased through at&t).

This makes sense. I'll will try to flash Sprint firmware on top right now. The reason I said tweaks/customization applied because the whole UI "Settings" of the change completely changed from Tmobile Pie to Sprint Pie (more buttons, header rename...) so I assume tweaks/customizations already applied when Sprint Simcard did its own things
Also I thought the base S9 Pie for U ver all the same. Only when you put the Carrier simcard in then they download their all carrier settings (Not in this case?

Carrier settings (APN, MMS/SMS settings, PRL, Roaming lists and related) are not quite the same when it comes to bands being enabled/disabled or carrier tweaks/customizations. Also I don't know if the base for the s9+ contains all the full carrier customizations/tweaks or not when it comes to android pie. If I had to guess I would say it probably comes with a somewhat generic one size fits all configuration... Perhaps along the lines of what the U1 firmware has.
Though I would presume that the base does not have all the carrier customizations/tweaks because the carriers release android pie at different times.
As an example (for illustrative purposes to explain my presumption) AT&T releases the new update before T-mobile does. T-mobile releases the update before Verizon does. Because Verizon would have been the last to release the update both AT&T and T-Mobile would not have any of the additions Verizon would have made.
When flashing the sprint firmware onto the AT&T phone you have you may need to flash the U1 firmware first, do a factory data reset and then flash the G965U firmware for sprint. Someone else might have some insight if this is still applicable for Android Pie, but when I flashed from sprint to t-mobile using the Oreo firmware that is the process I had to go through.

I would debate on the example (for illustrative purposes to explain my presumption) you had above, I don't think carriers are related. I would think Google/Samsung (Google may give the base to Samsung first then Samsung distribute to each carrier) give each carrier the base then each carrier goes customize their own settings with their own times to release to us.
Yes the correct way to flash to U1 then flash back to be clean (I guess And I did that when switch from ATT to Tmobile) But i have to much to setup again, so may just dirty flash Sprint now
PS: Still can't find the Sprint Pie in Sammobile website. Only Verizon and Tmobile and Generic ver

Shouldn't have to flash the phone should install the firmware as soon as you install the Sim card

All models are the same. Their just blocked in att firmware same goes for vzws B13. Your phone will install the firmware when you put in the sim card

You are right, I saw 25 and 26 now. Sim card will download and unlock the band needed

Yep. My S8 did it,so does my S9+

I am not sure if this would work or not and I haven't done this for a while. I might have the wrong service code or the menu option may have changed with android pie. So if I do someone feel free to correct it.
Note - if you see a message like RAT access/menu isnt allowed (or something like this) power off the phone, take the sim card out and power the phone on without the sim card in it. The process should work then.
*Open the phone app and enter ##DATA# (##3282#)
*Choose edit and if prompted enter a total of siix zeros as the MSL
*Select LTE to edit the active bands
From there you can enable or disable bands. If the band isn't listed you simply cant just add it. I would suggest flashing the carrier firmware as this would have it enabled.
Also I do believe that there are carrier customization/tweaks that may only be on the firmware from the carrier. Swapping the sim may change a few apps, change a few menu items and apply settings from the sim card onto the phone. It also may apply some (or perhaps most) carrier settings. I have not seen anything that gives me cause to believe that it applies all the carrier customization/tweaks.
If that were the case why did my g96u1 (or sprint g965u) firmware not show video calling or get provisioned for it, but flashing the tmobile firmware allowed for the feature to be enabled and provisioned. Also on the tmobile firmware I have had better signal retention and strength (not the signal bars, actual signal strength measurements on the phone) then with the unlocked firmware (or the original firmware that was on the phone with the tmobile sim).
If swapping the sim installs the tmobile firmware then that should have been all it took and I could continue to use the unlocked firmware, but this was not the case. The only features that were enabled were (outside of menu changes and app additions) VoLTE and WiFi calling. Now if this alone indicates carrier firmware specific features/tweaks/customizations can only reside on carrier firmware, then how could one declare it wouldn't also effect what bands are enabled/disabled. Like I said I haven't seen anything that says otherwise, but from what I have seen first hand there are somethings that are apparently only on the carrier's firmware that is not available on the others.
Hi guys, here in my city and another ones near recently we have some carriers with VoLTE enabled. I was thinking about reasons that Xperia X don't have VoLTE enabled... I tested in another phones that i have and it works perfectly. The SOC is a snapdragon 650 wich supports VoLTE and HD Voice features, also VoWiFi, according GSMArena it also supports 700MHz band, wich is the one that we have VoLTE here... I'm leting something scape? I also tried some build.prop configs what give-me some "toggles" access "Enable VoLTE" in network settings, i've set to enabled but isn't... So, our stock software don't have any implementation for VoLTE? I've already research about and don't find any satisfactory information...
Thank you,
Luiz
Some providers enable the Volte on the sim only if they see the sim is in a supported phone by them, if its enabled by default on the sim then the phone has to have selected the right modem. You should check to see if sony has specific firmware for your provider here: https://xpericheck.com/device/F5121 , and if it does you should flash the specific firmware if not your only way to make it work is to change some stuff in build..prop and check different modems (you can google to see how its done) and maybe you are in luck that some other provider has the same modem settings with your provider.
1. Check to see if your SIM has Volte enabled on it or you have a way to enable it (some providers auto activate it if they see the sim is in a phone accepted by them and for some you need to send an SMS or something to activate it )
2.Check on xpericheck if there is a specific firmware for your provider (if yes you should flash that , or just flash the customization file) and if not
3. Enable volte in build.prob then test different modems maybe you get lucky (only if you have root)
The phone supports Volte and it works smooth if your provider and sony released a firmware version for it.
I already try to enable VoLTE on build.prop, also searched for modems but no good results. I'm using TIM operator in Brazil on F5122, the only modem for TIM is from another Sony model, and not working yet...
