Hello, I am writing to inquire about a problem that I have.
I have the F240L, and wore the ROM "SphinX GPRO KK V1.5", all good so far, but I have problems with 4G.
I have only 2G/3G reception.
I've been to "Hidden menu"
Then I selected "LTE-only"
Then "Modem Setting"
Then "LTE Band Selection"
And I select "Band 7", which is used by my country Chile to the 4G network, but then I again I enter the same menu and was not checked. :crying:
Someone who can help me.
thanks
LTE band
Having the same problem here, but i think its because of this;
F240K for KT Corporation – LTE 900/1800, Band 8/3
F240L for LG UPlus – LTE 850/2100, Band 5/1
F240S for SK Telecom – LTE 850/1800, Band 5/3
these are the supported band for specific models. I Think it cannot be changed using software because this is hardware related.

And flash a modem Hybrid?
Or modifying buil pro?
Flashing a modem means flashing the correct radio that maches the hardware. So basically hardware baseband cannot be changed.So it won't work. And build prop is for ROM properties. You can't use it to change the baseband.

Hi All,
i just bought LG pro (E988) from Hong Kong, However, i found that it's not support 3G in Canada due to different frequency
( 850/1900 vs 900/2100). is it possible to gain more radio band reception by software way ? e.g Flashing ROM, Modem or etc.
Please help
Thanks

Id like to know this also, would flashing AT&T KDZ help?
Hi there
I have a unroot-unlocked L-04E and want to use it with Wind in Canada. I am going to secret menu 3845#*04#-> Networkmode and want to select WCDMA AWS but there is a Fail message.
Any advice about how to make it work. Flashing mode, m band etc.. (There is Rooting method for this phone on Japanese websites).
Also I didn't have any luck with LGL21 (au version of E970) to make it work with AWS band. just I discovered its modem is identical to AT&T E970.

Make sure the devices lte bands match that of your carriers lte bands. Dont look at 2g and 3g bands. Only lte bands. Second id say make sure your apn settings are correct.
And last is make sure in mobile networks you have global or gsm cdma and lte selected
---------- Post added at 11:22 AM ---------- Previous post was at 11:19 AM ----------
A lot of times this could be due to specific hardware not picking up propper lte bands or those bands not being enabled. Which u can google on enabling hidden lte bands. I didnt notice what model u had from the seller. I noticed u said manipulations of unlocking bl so where u sucsessful? Then its a h815 i believe which would be the global model. Which then could be software relTed or a settings issue.
I had not specified that it is a h815 international version but planned for a planned commercialization in Singapore. According to my operator the antenna 4g near my home uses only the band 800 which is normally compatible with ... I also have a lg g4 that works perfectly with my chip. All APN settings are correct .. Is there a way to force to use this tape?
I tried manipulation to unlock the bootloader with the official version of LG but it is an Asian phone .. I thought of a software problem so I tried with lg bridge that does not pick up my phone. Is there any other way?

What is the method ?
I have an AT&T LG Optimus G Pro e980 20h. We have 3G on the 900 mHz band. Is it possible to unlock this band in this phone? Does it have this band hidden? Could this be done changing to a custom rom? Please, help me with this.
I have gone through this forum, but have not found an answer yes...
Thank you very much....
yes, it is easy to do it.
i flashed my phone (e980) with e988-20c, then flash back att modem.
enable hidden menu to choose "WCDMA only", then "modem setting", choose "network mode" to enable WCDMA 900, you should see "success"
Hi, I´m from Portugal and my Carrier is MEO. For 4G they support band 20/3/7.
I want to buy LeTV LeEco Le Pro 3 X727 and it says he only supports 4G FDD-LTE: 2/4/5/7/12/17/29/30/38.
LeEco Le Pro 3 X720 support 4G FDD-LTE: B1/2/3/4/5/7/8/20.
IF i install Lineage rom, or another Rom for X720 on x727 model, do he gonna support the same bands as 720? the 2/7/20?
Thx in advance and sorry for my poor English.

Also to answer your question, the supported bands are written to the NVRAM of the phone and aren't part of the rom. So no, if you flash a X720 rom on an X727 you won't unlock any addition bands.

Yeah, the baseband chip support all bands as it's part of the SoC. The modem driver is kind of generic. It reads a bit of read only storage on the phone called NV_RAM which contains stuff like the bands the phone supports, the IMEI, etc. So it is sometimes possible to unlock additional bands by editing the NV_RAM

So editing this in the Build.prop makes all x720 custom roms compatible with x727 (in theory)
*EDIT - Of-topic: Melbourne look likes the best city ever. Moving as soon as possible
I have the LEX 727 from Amazon but no working bands 2 or 4, any ideas to help me? changing the rom to the chinese version? something in the modem, baseband?

NVRAM isn't in the build prop, its a special bit of persistent memory in the phone. To edit it you need to put the phone into diagnostic mode and use QPST.
And yeah, Melbourne is pretty sweet. I hope to see you here soon!
