V30 [H930] LTE doesn't work - LG V30 Questions & Answers

Greetings everyone,
I have a problem with my LG V30 (H930) data.
I'm from Argentina, and my carrier uses bands 2, 4 and 28. The problem is that when I go to the "hidden menu" only band 28 is working fine, when i tap on band 2 or 4, it says "FAIL".
If i go through my phone specifications, band 2 and 4 should work well.
I have already upgraded to "H93020u_00_OPEN_EU_OP_0528" on DL partition with LGUP.
Sorry if i don't speak english very good.

Some possible answers...
1) IF you have EU H930 LG V30, then yes, you should have LTE bands 2 and 4, in addition to LTE band 28. You shouldn't need the hidden menu.
EU H930
2G GSM: 900 / 1800 / 1900
3G (HSPA): 850 / 900 / 1900 / 2100
4G LTE: 1/2/3/4/5/8/12/17/20/28/38
(some sites don't list LTE band 2 for EU H930)
Are you SURE you have EU H930 and not another H930 variant like H930D/H930DS? Just because you flash EU H930 firmware over H930D/ H930DS that will not give you EU H930 bands. H930D/H930DS do NOT have LTE bands 2 & 4, but do have LTE band 28. This sounds suspiciously like your situation...
H930D/H930DS
4G LTE: 1/3/5/7/8/20/28/38/39/40/41
Search your IMEI online in IMEI database (see link below) and it will definitely tell you what H930 or H930 variant you have. It's possible whoever used the phone before you (if you bought used) flashed it to EU H930 firmware -- but it's really H930D or H930DS.

2) Apologies if I"m making assumptions, and I don't know what part of Argentina you live and travel -- but maybe your carrier only has LTE band 28 in your specific area? Have you gone to other places in Argentine where you know other people receive LTE bands 2 & 4?
For instance, my carrier AT&T uses LTE bands 2, 4, 5, 12(17) nationwide. However, in the specific area where I live and work (about 30 miles), AT&T uses LTE bands 2 and 12(17) -- and a few towers with LTE band 5, to supplement 2 and 12(17). If I went into Hidden Menu and tried to force LTE band 4, it would FAIL -- because there's no LTE band 4 in that area. Whereas if I travel north out of the city, suddenly I start to see LTE band 4 almost exclusively, and the other LTE bands disappear.

If either of those are not the answer, then Master Reset your phone, and flash most recent EU H930 30q KDZ via Dev Patched LGUP in REFURBISH mode.

bro te comento en nuestro idioma tenes q poner un firmware nougat del us998 y despues pasas a Oreo, entonces recien podes pasar a pie usando el modelo que quieras pero con la opcion de flashar ddl partition sin tildar las opciones de modem xbl y xbl2 asi seguis manteniendo la baseband de us998 q es la q mejor anda, o podes poner la version pie de us998 q salio hace unos dias.
busca los thread del metodo frankestein , y tambien de como convertir us998 a h930 que ahi tenes todo lo que te haga falta.
recorda usar el lgup dual mode que es el que mejor anda y el archivo q esta creo en el thread de us998 nougat firmware.
a mi me sirvio en mi h931 y ahora lo tengo con un firm de h930
saludos y cualquier cosa avisa.

Please write in English on XDA. It's actually a rule. You can write in another language but also translate in English.

bro I commented in our language: You have to put a firmware nougat of us998 and then you go to Oreo, then you can just go on foot using the model you want but with the option to flash ddl partition without ticking the xbl and xbl2 modem options so you continue to maintain the baseband of us998 which is the best one, or you can put the foot version of us998 that came out a few days ago.
look for the frankestein method threads, and also how to convert us998 to h930 so you have everything you need.
remember to use the lgup dual mode which is the best one and the file that is created in the thread of us998 nougat firmware.
it served me in my h931 and now I have it with an h930 firm
greetings and anything warns.

DO NOT CONVERT H930 TO US998.
Even if you untick the modems, what good does that do? It's the modems that's giving him problems. He's not receiving LTE bands 2 & 4.
Yours is exact opposite. You went from AT&T H931 to US998, then flashed firmware to H930 while keeping US998 modems. You have US998 modems.
He has EU H930 or perhaps Mid-East/Africa H939D or H930DS modems and can't change that.
So, Frankenstein (converting one North American variant to another) doesn't apply to his situation whatsoever. Unless he's mistaken and he has actually has AT&T H931?
If he searches for his IMEI in the database link I gave, he can confirm what phone model he has. Then we can go from there.
