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.
I've purchased a ZE551ml in Taiwan, here in Chile we use 4GLTE 2600(7), the TW version doesn't support that band, I've flashed the latest firmware, and now the version is "LRX21V.WW-ASUS_Z00A-2.13.40.13_20150401-8390_USER044030427_201501060109", this means I'm in the WW firmaware version? If not what can I do, and add support for 4GLTE in 2600(7) band?
Thanks for your help.
It is my understanding you will need to purchase a WW or US version to get band 7 support. The WW version in France should be released soon. No word on the US version.
I am not sure if there are different versions of ZenFone 2 ZE551ML (as for the hardware). I bought the ZE551ML from Taiwan about 2 weeks ago. It came with a WW firmware & I am living in Romania (so Europe). I did had some issues with LTE even after the last OTA update (the network kept dropping again and again). I solved the issues! For me, I only had to change the phone's ATP settings with the ones required by my network operator (Settings -> Wireless & Networks category -> More -> Cellular networks -> Access Point Names). Now I don't have any issue. Maybe you could try to find what settings are required by your network operator.
Thank you for saying this. I also have a TW ZenFone 2 and it came with WW firmware. I thought it was a mistake.

Although it's WW, it's not the same build as real WW model.
I also have Zenfone 2 TW version. Re-flashed it to WW just to make it more generic.

Yeah, true. There is, for example, an asian-market game-store app, pre-installed. Even though my phone came in with a WW firmware, I chose to flash it with the WW ROM from their website (I thought it would have been a more light version with no 3rd-party apps like Kindle, TripAdvisor, etc...but it's the same )
My phone is working with 3G, and network APN are well recognized. Only have problem with 4G. I think the hardware must support all bands, it's a feature of the chipset. So I hope that with a different version of the firmware fue 4G could work.

For me, the APN was recognized, as well...but I had to make some changes in some names. I hope you will get yout problem solved, somehow.

How do you figure out if your Zenfone 2 is TW version if I may ask?

On the box check C.P/N barcode. Last two letters TW means Taiwan version.
Also, Taiwan version when bootы first time, suggests Chinese Traditional language by default.
Change FIrmware???
I keep reading different people saying: "I had CN firmware so I flashed WW firmware ...." while on the Asus site, from where I got the firmwares, says "DO NOT FLASH FIRMWARE OF DIFFERENT SKU VERSIONS" ... it explains further "CN SKU should flash CN firmware".
Can someone lead me in the right direction and tell me how to flash my CN version to WW version? Do I just flash the WW firmware off of Asus's site?
here is the bands it shut support from the differend versions

It seems that installing a different region firmware will work, but the bands won't. However, i know that the ZenFone 2 uses the same LTE modem in all these ZE551ML devices (Intel XMM 7262 Slim Modem—LTE Advanced). But this modem may come in 2 variants (not sure). I contacted Intel and Asus for more info regarding this. I know that there was an issue with Galaxy S5, for example, where some bands weren't allowed by default (market related), even though the phone supported them.
Flashing firmware from different region won't change supported 4G bands. Bands support relies on region of phone, which is defined in SFI (it's simpler version of ACPI found in PC) OEM1 table, and it's not touched by flashing procedure.
Although, it may be possible to spoof HW region in kernel. But it requires unlocked bootloader.
There may be another way to unlock bands: copy one region specific file set to another region set, but it may not work. This method doesn't require unlocked bootloader.
BTW, there is one more region not mentioned above, called FULL. So, according to name, it should support frequencies from all regions.

Taking a look at the recovery last_log file, the latest WW_ZE551ML_2.15.40.10_20150425 firmware include quite a few ifwi Image FW versions:
ifwi: 0002.50E6
ifwi: 0002.00E6
ifwi: 0005.00E6
ifwi: 0088.0163
ifwi: 0094.0171
ifwi: 1002.10E6
IFWI FW Major version numbers (the first four) have to match before it will flash the firmware.
I suspect these may be the different regional modems in our device, but allows ASUS to push a single firmware.

There are exactly 6 ifwi_ files in ifwi.zip inside the ROM package. But I can't figure out their versions... Maybe we can flash an ifwi with different major version with xFSTK Downloader?
EDIT: Finally got something...
0002.00E6 ifwi_ann_a0-mofd_v1.bin
1002.10E6 ifwi_ann_a0-mofd_v1-DBG.bin
0005.00E6 ifwi_ann_a0-mofd_v1-DSDA.bin
0002.50E6 ifwi_ann_a0-mofd_v1-SIL.bin

0094.0171 ifwi_ann_a0-mofd_v1-ze551ml.bin

doing so can we change modem region and available lte bands?

Maybe not. (I'm wondering if -DBG version allows unsigned kernels, like unlocked bootloader, and if phone will recognize it)

I don't hope much. There are 2 different ifwi binaries:
Code:
ifwi_ann_a0-mofd_v1-ze550ml.bin
ifwi_ann_a0-mofd_v1-ze551ml.bin
But only one DBG version.
It means, DBG version is for special DEBUG device, with probably special hardware config, neither ZE550ML nor ZE551ML.
It's possible, that ZE551ML and ZE550ML are the same at bootloader stage where existing differences are not touched. But if there is some initialization or even access of device specific config, then wrong bootloader will eventually brick device.
For some unknown reason ASUS choose not to hardlock write access to boot block. It's only "soft locked". It means, with root access you can enable write access and then using dd, you can re-flash boot block. Btw, boot block (IFWI) is written not as-is. Updater reads some kind of settings/config from existing boot block, then copies it to new boot block and then writes it back to flash.
So, it's extremely dangerous to mess with boot block flashing!
On my D855 No Brand EUR, I'm unable to enable see the VoLTE and WIfi Calling menù.
I've tried both with v20h-eur and v20p-eur. firmware
Please can you explain to me if there's a wait for my D855 No Brand EUR to have VoLTE functionality? For the moment I need only to see that feature on the Setting Menù to make sure that it will work with providers that alredy improved VoLTE.
Thanks a lot.
Afaik, it is found only on Vodafone branded roms.
If you install the 20p KDZ you'll get it.

Now I have v20p-EUR-XX but I don't have the VoLTE option under Settings Menù.
I've also tried to enable it using 3845#*855# under LTE Only setting VoLTE radio on and rebooting the phone without success.
Always on 3845#*855# menù, if I go into IMS it returns the following error: "IMS VoLTE packages doesn't exist" so I'm very confused.
Is there somebody that has a No Brand G3 and is seeing VoLTE Settings menù?
Hello, i just switched to LG G4 from my LG Optimus G PRO. I was using *#*#4636#*#* in order to select the network type i want (LTE Only, LTE/WCDMA etc) . That code is not working on my G4. Is there any way to enable it or any idea why it is not working? Or any other way to select any network type i want? My Android version is 5.1 and the Software Version is V10d-EUR-XX
Use *#LGMENU#*815# -> Field Test -> Modem Settings -> RAT Selection
Also remember some models, like the Taiwanese H815, are CSFB only, i.e. no VoLTE, which means that if you set them to "LTE only", you will only have data and not be able to place / receive calls.
There is also the Settings (General) -> More -> Mobile networks -> Network mode
Hi, it is possible and safe to change the firmware of LG g8s g810ea to g810eaw? I thought about flashing new firmware with LG up.

I know nothing about the G8s, never owned one, but generally speaking, pretty sure changing the firmware is much the same as the G8. There are some no no's, like if you have dual sim to single sim, or vice versa, but you don't say anything about the firmware you're referring to... it might help to know why you want to change, iow, what are you trying to accomplish?
But more than likely, it shouldn't be a problem. I'd suggest first to ask on the tele group for the v50 / G8 devices, they are more international experience there and will be more certain. Cheers
Thank you for a quick answer. My LG G8s is a g810ea version. I won’t to flash g810eaw firmware because the are fresher builds. Newest build for eaw is 30c from 7/2022, when ea 30a is from 12/2021. Also LG Germany declared Android 12 update. Morover I couldn’t find setting for VoWifi and Volte. All firmwares are meant for LG G8s, which is available in 3 versions g810ea, g810eaw and g810ra.

From what I can see on the firmware pages, should be okay. Always keep in mind that ea individual rom has certain bands enabled, so be sure the bands it has will meet your needs.
Also, vowifi and volte are dependent on your carrier, not just the phone. The G8s is capable of both, but if your carrier doesn't allow them then there's no way to make the work. And, some carriers (like US at&t), only allow it to work on their phones - or at least that was the case at one time.
It's always best to flash an 'open' version Rom, if there's one available with the bands you need, and your carrier allows a phone on their network that isn't running their specific rom (usually an mvno type carrier is best).
cheers
