Thankyou!

We need someone that have and can go inside the file 00028874.zip, because i think it's a simple text/number file like 524356 (for band 3+7+20) or similar.

No one familiar with qpst and band aggregation?
[Samsung Galaxy S10 Guides, News, & Discussion] SteveHG:
The modified file 00028874 in the zip archive is for Russian operators only.
[Samsung Galaxy S10 Guides, News, & Discussion] Gho57:
yes, I think there's the new band, or aggregation hex number inside. Russia bands are different compared to EU, that's why we need some expert who can speak russian and ask to 4pda forum

Verizon is CDMA based right? I keep seeing posts on saying it's GSM only, I'm assuming it would work on Sprint too right? Have you had any hiccups or missing features on Verizon?
[Samsung Galaxy S10 Guides, News, & Discussion] monroe0328:
Edit... Well the Russians did it... Hope someone can knock this out for us carriers!

Ok so on verizon 9750 out the box...

Works...

4g (all verizon bands supported), texting, picture mail (only with 3rd party apps like Google messeges), volte, hdvoice with other verizon people

Not working/missing feature...

2g, 3g, picture mail (I guess it's just mms that's not working) with stock messenger, wifi calling, carrier aggregation (sucks I know)

I've tried flashing 975U csc in Odin and it won't go, even had a friend who knows **** try and fix the flash able, but still no go.

I just got magisk working so I hope that gives me a better chance at something, of course someone smarter than me will prolly have to figure it out.

Sprint DOES NOT WORK OUT THE BOX...

I'm guessing because CDMA isn't working (firmware or csc issue?) Sprint authenticates on CDMA so the phone can't register with the network.

That's when I got verizon sim, and I'm assuming they authenicate via LTE so the phone gets registered on the network and works

thanks for the explanation.

it takes an engineering degree XD

The only things we need is the aggregation for the b20 band with band 7 and-or 3, because the phone supports and connects with every EU band (1,3,7,20) but aggregation is only for the 1,3 and 7 not the 20. Do you think there's a chance to add this?

[Samsung Galaxy S10 Guides, News, & Discussion] Tuntu:
With https://play.google.com/store/apps/details?id=tw.rmstudio.mt.android.ltebandcalculator&hl=en we can calculate the number of the CA band.
[Samsung Galaxy S10 Guides, News, & Discussion] Gho57:
I think if we delete the file in / nv / items_files / modem / lte / rrc / cap / prune_ca_combos ( backup first! ) we can have more aggregation until we put a new sim or firmware or ota, Russians say.

S10 HK version supports all Italian LTE bands 1,3,7,20, so it would be useless edit or create a new NV 00028874 file, what do you think?
[Samsung Galaxy S10 Guides, News, & Discussion] yakapa40:
as you can see in the link of post 82 it's not the same method for NV1877 and NV6828 so maybe it's also another method to calculate NV28874

CA is controlled per combination so that should be the inactive combination list. It'll activate one of those combinations depending on your SIM cards IMSI.

deleting the list "should" enable all combinations of CA to be used. however I read this gets auto refreshed when you change locations by android.

I haven't tested any of the tools yet personally but if you aren't able to modify the file "RFNV_LTE_CA_BW_CLASS_COMBO_I" (NV 28874) using QPST/QRCT/QXDM you can also try using CDMA Tool DFS.

Hi Guys!

I own an S10+ (hong kong variant) and I live in Europe (Hungary). The phone is working fine here, but I have some trouble with the LTE speeds here. They are very low and the latency is high. This is because the phone only uses single LTE (4G) band, as it turned out. I did some research and got enough knowledge to change settings in the Qualcomm modem inside the phone to enable Carrier Aggregation.

My provider uses LTE B3 and B20 bands, and there is one another B7 which is also used by another providers.

I've calculated in LTE Band Calculator app that this 3 bands hex number is 524356 (B3+B7+B20)

What I did so far is:

1. Installed QPST and QXDM.

2. Enabled Diagnostic Mode by dialing *#0808# and set it to RMNET + DM + MODEM + ADPL.

3. Connected to a PC running Windows 10 Pro x64 and it immediately recognized it as

Qualcomm HS-USB MDM Diagnostic 90B7 (COM14)

and installed the required drivers automatically.

4. Launched QPST, verified that it detects the phone and then launched QXDM.

5. Set the target port to COM14 and it recognized the phone too.

6. Searched in RF LTE Category for RFNV LTE B20 CA BC CONFIG and set it to 524356 the pressed

Write

and repeated this with B3 and B7.

7. Waited for about a minute and then unplugged the device, then REBOOTed it with the button in Diagnostic Mode Settings.

The problem is that this is not working. I've checked in service menu and it shows CA-Not Config 00. I'm not getting 4G+ signals anywhere, even next to a CellTower the speeds are better but not as good as with other phone with 4G+. :eek:

I don't really know where to ask for help and just found this topic so I hope someone can help me.

[Samsung Galaxy S10 Guides, News, & Discussion] SteveHG:
Are VoLTE and CA working now with this file?
[Samsung Galaxy S10 Guides, News, & Discussion] scarface245:
Yes, CA is working really well on B3 and B20. However VoLTE is not but I don't think that file has to do anything with it. What I know for sure about it is enabled by my carrier and I need to install a profile for it which at the moment I don't know how I will do.

Probably its not working because its a "small" carrier and samsung doesn't include configurations for these in the software. One more thing, I've tested the phone a month ago with another carrier's card and VoLTE was enabled by default so it should work without replacing the file in rflte, but of course CA wasn't.

[EDIT]

About that file (something like 0002885), when I deleted it with EFS Explorer I did a back up first, then deleted it, EFS just moved the new one but it wasn't there. I'll double check it when I get to my pc but I swear it wasn't replaced just deleted. So maybe just deleting the factory one enabled the phone to use the configurations I set in QXDM.
[Samsung Galaxy S10 Guides, News, & Discussion] scarface245:
Okay, I found it. I don't know what russians did with it, but it definitely works with B3 B7 B20, maybe they got it from an European model and modem configs are similar between Qualcomm and Exynos or I don't know. VoLTE is not working, but it is because of a missing profile for my carrier. I don't know at the moment how I will fix, maybe switching carrier is better option XD.

Cheers,

[Samsung Galaxy S10 Guides, News, & Discussion] scarface245:
Of course, all you have to do:

1. Download and extract this

zip file

: 00028874.zip (Attached by SteveHG @ post #86 in this thread),

2. Download and install QPST

3. Enter into Diagnostic Mode on your phone by dialing *#0808# and then select RMNET + DM + MODEM + ADPL (Do not close that app until we finish)

4. Connect it to a PC, wait for the drivers to be installed, check in Control Panel > System And Security > System > Device Manager if the phone is listed under PORTS (COM & LPT) something like

Qualcomm HS-USB MDM Diagnostic

5. Run QPST as Administrator and wait for it to recognize the phone.

6. Select Start Clients > EFS Explorer, in Phone Selection click

OK

, then wait until it finishes reading the memory

7. Go into nv > item_files > rfnv folder then find

00028874

, right click on it and select Copy Data File To PC browse a location then click OK (This is important because this is the factory config file so we need to back it up by copying to the PC so in case we can use it.)

8. Right Click on the file (

00028874

) in

EFS Explorer

and click Delete

9. Right Click somewhere inside EFS Explorer where the files are and select Copy Data File From PC

10. Browse the file extracted from Step 1. (00028874) and then click OK

11. Head back to the phone and press REBOOT wait for it, enter your PIN Code, then you are done with changing config for Carrier Aggregation I think :cool:

Note,

IF the steps I mentioned above are not working and you are not getting LTE-A or 4G+ Aggregation in Europe

then you should complete the steps from my post #131 and if it is still not working, let's hope there is someone smarter who can explain the issue XD Good luck with it. :svetius:
[Samsung Galaxy S10 Guides, News, & Discussion] Scavenger01:

According to frequencycheck.com there are 16 records of countries and carriers that use B28 too. From them there is only one country that is in Europe and it is France. In France B1 B3 B7 B20 B28 bands are available for LTE which means if you complete the steps from my post #141 then you should have LTE-A or 4G+. If your country is not France or any European country then I can't help you at the moment because I can't read that aggregation file from the Russians and it is for European bands.

Well, you know, I was thinking about that two Bands 7+28 and I think it is worth a try replacing that aggregation file anyway. In worst case you have to put the factory file back if you are not getting 4G+ with it which is your current situation as you mentioned, and maybe there will be someone who can figure out how we can edit that aggregation setting file.
