Hello My Friends
Sorry English Not First My Language
i Want Buy This phone G930F Verizon Carrier
Can i use this phone With 2G Network By Change rom or any way ?
See Attached Photo To This Post to know what i,m talking about .
Regarding the observations of the professors can i use this phone on 2G netowrk ?
Verizon doesn't do G930F models, Verizon's are G930V's. They come with different network modems intended for US carrier networks which differ to international, also a different CPU chipset and locked bootloader.
So I'm pretty sure it's a fake and why it says LTE / CMDA / UMTS and not LTE / 3G / 2G, because it's a G930V faked to look like a G930F. For reference my G930F says LTE / 3G / 2G under that menu.
A G930V can't be flashed with a ROM because it has a locked bootloader.
If you can boot into download mode without the seller noticing (Vol down + home + power) the real phone model will be in there.

Hello,
I've got a LG Phoenix 2(K371) phone that I bought from Bestbuy and unlocked through AT&T
The phone is supposed to support the UMTS B1(2100 Mhz) frequency (as stated in specs).
I'm in North Africa right now for a business trip and unfortunately I wasn't able to get any 3G data with the local carrier that uses the UMTS 2100 Mhz frequency, I'm stuck with only 2G while my other phone works just fine.
I tried to change my Network Mode from 4G to 3G but the Network mode menu is missing!!!!!!
My questions are:
1- Does the K371 really supports the UMTS 2100 Mhz frequency ?
2- How can I change my Network mode from 4G/Lte to 3g/WCDMA?
Thanks
Did you ever get this sorted out? I am in Germany and can only get 2G also.
Same here in the UK! Only 2G.
My understanding is that either the official specifications of the phone are wrong - it doesn't support the HSDPA frequency of 2100 MHz, or (most likely) this frequency is disabled in the phone software settings since [email protected] doesn't use this frequency in the US. In any case it is very frustrating: I bought this phone convinced it is going to work while I am travelling in Europe, but obviously it doesn't as 2G data connection is useless.
Same problem in SE Asia. Phone doesn't have the right LTE bands but HSPC should work. Only getting 2G. No option in the hidden menu to change the modem RAT settings that I can see. *#546368#*371#
Anyone have any luck using the k371 overseas?
Same here...
I tried every single method I know in hopes that I could root the phone, but no luck!!!
I believe at&t disabled the said frequencies....
Our only bet is a proper root, and a custom rom..
any update on no UMTS 2100Mhz?
any solutoion on this issue?
I have found a solution. I am using it outside the US. I contacted my cellular provider, gave them the phone name (LG K371) and they sent me a text message with automatic settings for their data network. As soon as I opened it, I got a message like "data settings have been updated" and now it works on 3G and 4G without any issues. You may also be able to find these data configuration settings on your cell service provider's web site.
Seriously???
Please let me know is it AIRTEL service? since i am from INDIA.
we have the same problem in 2 mobiles..
Hmmm
I tried of calling and received setting for MMS , GPRS, INERNET but still i m seeing 2G symbol as E - edge detection
Please help me
Hi this is sainath
am also facing same problem, any one got solutions
please give reply.

Sorry for a late reply, but here's the real scoop about the LG K371 (AT&T)
First, being a "cheap" LG phone, there are very few bands actually included, and they only cover the main (not all) AT&T US frequencies, therefore it's no surprise that doesn't work on all overseas carriers. Again, they are covering only major US bands, and despite what it shows on the box or specs it may not be always true. B1 (2,100Mhz) band has different sub-bands, therefore it doesn't mean that the US B1 will work on an overseas B1, let alone the air-interface (2G/3G/4G/LTE) may not all be supported even if this sub-band exists.
Second, being that it's an AT&T phone, they are knows to load firmware with major restrictions for band selection called RAT Restrictions, which cannot be undone unless you can reflash it with a non-customized firmware, but you can't do that either due to the locked bootloader. A better option is to always go with the un-customized or Tmobile K7/K8 because they always have a lot more bands enabled than the AT&T version. Better yet, go with a Samsung which have more bands even on the AT&T models.
Bottom line, "cheap" phones along with AT&T restrictions will not work everywhere, despite the specs, and there's nothing you can do about it.
And my favorite old adage is "You get what you pay for!" LOL
I have been trying to get my LTE working on my Samsung S8+ SM-G955FD with Freedom mobile. I have updated the CSC to XAC and GLW from the development forums and the phone will not connect to LTE at all. However flashing it to tmobiles CSC I was able to get LTE as it uses the same band 66. I initially got LTE by selecting the network operator "Home" once I lose connection from LTE to 4G it will not automatically reconnect back to LTE unless I select the network operator again. Any suggestions on fixing this?
Same issue with Reliance JIO (India) using VO LTE. Seems the phone does not support it either (the 6GB Ram Model)
up!
my 3g does work but lte not always!
I found this article around flashing csc, it seems like it's proven to work when they are the same model eg both g950w.

I would like to ask if you rooted your phone and changed the CSC as per instructions given in the Droidview website?
If you did, and the results were not satisfactory, then you would have tripped Knox, but gained little.
I am in the same situation, and am considering rooting the phone to try the method in Droidview.
Thanks.
I got s8+ from freedom and trust me I absolutely hate their reception. On a drive home or from I get interruptions of voice call for 5+min (highway drive) in some areas. Anywhere in US call reception is hit or miss. In Canada isnt always great other. Now for LTE well, it ok if you catch LTE signal. Allot of the times im on 4g. Speed are very slow. If im lucky I get LTE. So i don't know whether its the service or the phone but im not happy. I'll pay of this phone and move back to FIDO or on US network. Freedom is garbage to me. Im all over the city, country and north america - freedom isnt great for me. Fido was excellent but i didnt get any credit on the phones, in US fido rates are very high.
Having received the S8 from Gearbest , and inserting a new Mintsim sim card I have been unable to get a data connection using the current MintSim APN settings. I am not a real phone teckie but I almost believe there are no options to make (via engineering mode) changes to get the phone compatible with U.S. carriers. Any suggestions would be helpful.
Not sure if updating the modem.img is an option. I don't see too many US carrier phones using the MTK6750T processor. I just get 2g edge on t-mobile. Not a bad phone if I could get 4g.

I have considered buying one of these phone's myself as it does look rather nice
This phone supports bands
2G: GSM 850/900/1800/1900MHz
3G: WCDMA 900/2100MHz
4G: FDD-LTE 800/900/1800/2100/2600MHz
AT&T vs T-Mobile (Mintsim)

https://www.att.com/esupport/article.html#!/wireless/KM1069631
There is a comment about the Doogee Mix 2 regarding support on the at&t link which shares the same bands.
I do not live in the USA so cant really comment too much about what does and does not work.
Hello,
I have a S7 SM-G930F with G930FXXU2DRA9 official ROM, without root and I noticed a problem on the aggregation of frequency bands.
My mobile operator uses 800Mhz (B20-FDD) and 1800Mhz (B3-FDD) tapes to make 4G + at 150Mbps.
The S7 is unable to aggregate these two frequencies, I also tested my sim in an S7 edge and same problem.
In the menu engineer with the code * # 0011 # I see that the S7 hooks well the two frequencies but without the aggregates.
Which means that I only have normal 4G on 1 frequency.
I put a sim of another operator in my S7 which has a 4G+ network with 800Mhz + 2600Mhz, and I have 4G +.
To see if it's not my sim that's the problem, I put it in a Oneplus 5t and there I have 4G + with 800Mhz + 1800Mhz.
The problem come from the S7 who do not want to aggregate.
Have any of you noticed that?
If I install a custom rom or flash modem, will that fix the problem?
Flashing your carriers Home_CSC and CP files are probably your safest bet. But if you bought it from your carrier then it should already have these, if you didn't it's probably using the stock CSC which may not be configured for your carriers network.
updato.com or sammobile.com should have firmware for your carrier, if you don't want to lose data make sure to flash home_csc. Normal CSC will wipe.
Hello,
I had thought but my operator does not sell branded phones, so no modified csc.
There is just one application that the operator makes available to automatically set up the APNs, that's all.
So I flash the modem + the csc from 3 other operator in my area using the same standard 4G FDD, the problem remains the same.
The only change is that I had a better network hang on some modem.
This is strange it is as if on the combination 800Mhz + 1800Mhz the Carrier aggregation is disabled, and that as soon as there is a higher frequency, 800Mhz + 2600Mhz, the Carrier aggregation is activated.
Unfortunately the Hidden Engineer Menu, allowing to make deeper changes to the connection mode has been disabled with Ota samsung
Hello there, my friend bought pretty cheap S7 from EBAY, everything was new, un-opened package, brand new phone.
BUT when he tried to flash it, then the problems started - Odin won't flash G930F firmware on this phone, then I started to research
- Model on package: G930F
- Model on back of the phone: G930F
- Model on the sticker on the back: G930F
- Model on device info and baseband: G930F
- IMEI number the same on: package, back of the phone (on the glass), sticker on the phone
buuuut:
- Bootloader versions starts with: G930A...
- CPU-Z showing Qualcomm CPU
Anyone know what's going on? The sim-card works in EU (Poland), LTE (4G) working, everything woking. I just can't flash G930F firmware because Odin won't let me to do so and DOWNLOAD MODE says G930A.
The software is only partially translated from what I saw...weird thing. Also on package there is a big sticker "EUROPEAN SIM CARD ONLY"
Maybe somehow I can force G930F bootloader flash? I don't care if it'll be bricked. Of course if there is a 99% brick chance, let me know
Can someone help me? Cheers!
You might have a fake device.

@sergatiuk - noo, of course it's not the case! I wouldn't be so dumb to try to recover chinese phone
I had S7 (real G930F) for 2 years before. This one I'm trying to repair is 100% the same, original phone. There is only something wrong with the firmware
Update: in recovery it says: samsung/heroqlteuc/heroqlteatt
7.0/NRD90M/G930AUCU4BQA6
Cool ! just making sure - I did get one of those lovely chinese S7s once...LOL
Best of luck figuring it out
I think I found something on a Russian forum:
Hello
Many in the same case receive after the purchase:
-a samsung GALAXY S7 Engraved SM-G930F on the back
-in terms of nougat parameters 7.0 for my case, all suggests that the s7 is a SMG930F version (can read BASEBAND G930FXXS4BQC1, same value for BUILD NUMBER). We could stop there but ...
... it is indeed a samsung SM-G930T (usa version on t-mobile operator) made up in SMG930F (global version), the latter being easier to sell and more profitable than its American counterpart since well better equipped processor level and frequency bands, although it has everything you need to capture the full potential 4G / LTE AND 4G + / LTE A in Europe and elsewhere. (see below or go to GSM ARENA)
We can say that we did not get out badly in the end, but the phones are undergoing unexpected changes software and unless otherwise opinions not possible with a tool like Odin on pain of getting the famous message "SECURE CHECK FAIL: (PIT) ".
With the application phoneinfo we get some rather intriguing details about the Rom:
1 an original bootloader so US G930TUVS4BQC1 (its role is similar to the bios, it is included under the acronym BOOT in odin)
2 a version of the original baseband so US and not European (this time the real value G930TUVS4BQC1 is obtained with the app phoneinfo or similar)
3 the OS is European G930FXXS4QC1 (pda or pa in odin)
4 an original csc (country dirty code) so US SMG930TTMB4BQC (csc in odin, here it is a single csc TMB so T-mobile)
5 a knox counter at 0x0 despite all this
The actual version of the bootloader ALSO appears in download mode, the bootloader remains unchanged in order to exploit the configuration of the motherboard of origin, which remember the American is equipped with a processor qualcomm 4 cores instead of exynos Octa cores for non-US versions, which is of course confirmed by the application.
On the network side, the network card will capture all the European bands in 4g / 4g + 3, 7 and 20:
GSM / HSPA / LTE
2G bands GSM 850/900/1800/1900
3G bands HSDPA 850/1700 (AWS) / 1900/2100
4G bands LTE band 1 (2100), 2 (1900), 3 (1800), 4 (1700/2100), 5 (850), 7 (2600), 12 (700), 13 (700), 20 (800) - G930A
That said, we realize that we are doing now with 4 cores less CPU level, and a band in less 3g (900mHz little or no impact).
For the winnings and unless I am mistaken, the GSM ARENA website indicates a micro SD slot that can accept up to 512GB against 256GB for other versions outside the USA.
Much more than a simple detail, OTA updates require a concordance of elements 3 and 4 contained in the firmware, which is not the case at all as described above. The solution is to reciprocate by flashing with ODIN for example an official ROM of the operator t-mobile, ATT, sprint or verizon depending on the case to match the CSC with the PDA. No worries to be level network, we keep all the frequency bands mentioned above after the installation of the original roms so 2g / 3g / 4g / 4g +
In summary, the phone has been set with a mix just enough to sell a samsung American under false air of global version if you do not look properly ... but still the update impossible to achieve should to arouse the suspicions, at least, as long as the scam is worked out that way.

Hi,
A bit late I know, but I am in exactly the same situation.
Last month, I bought a G930F which has a G930A (Snapdragon) mainboard.
Its a boxed G930F and the case has the same IMEI and 'G930F' engraved on it as on the original box. Note the serial number engraved on the case does not match the serial number reported on the phone.
I've put the details here...
https://forum.xda-developers.com/att-galaxy-s7/help/sm-g930f-actually-sm-g930a-boot-loader-t4018649
I think its been repaired rather than faked.
@Kamikiri , What did the you do with your phone in the end?
I am thinking of updating to a G9930F UK CSC and latest G930FXX PDA or perhaps latest G930U Firmware (AP,BL,PDA,CP & CSC) - any reason why I shouldn't or any gotcha's?
Any clues would be appreciated!
BestW,
YYo
