Hi ,

update june available on BRI today :cool:

:good:
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] Abra_Cadabra:
Thanks [MENTION=1000401]cheetah2k[/MENTION] for the instructions. Can confirm also that updates work fine after the change in CSC. Immediately got an update with the June security patch.

Now if only we could find some software way to enable eSIM :) then this phone would be perfect.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] st3v3nBB:
I'm looking everywhere to find a solution... there is a section here on XDA where somebody has done it for Exynos and let user try on SnapDragon, but didn't see any success.

Hi

I changed my CSC to TGY by samkey in 5 min and i get 5G also i am in last update (Jun) ??.

I try many methods but not working except samkey.

Now I have problem with Samsung pass that say my phone is rooted and it's not working also Samsung health not working but my phone not rooted ever.

But i have a note my bootloader in unlocked, is it the cause???
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] west2cool:
If your phone was rooted before you change csc. Just download the latest firmware for TGY and flash with odin or factory reset it.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] {M+H}:
I will wait the next OTA update, if it not solve it i will flash firmware with odin.

But do you think the unlocked bootloader affects or what ?
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] stefauresi:
Hi,

It's strange because Samkey does not supported SM-G9880 :confused:
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] west2cool:
Where its says samkey does not support G9880 its to with sim unlock the device and not changing the csc.

I failed to update my SM 9880 from BRI to TGY with Samkey. I was logged in with enough credits etc, the app started, phone rebooted and then the app said it was unable to finish the process.

Anyway I'm on the last BRI update, with 5G enabled and VoLTE available too.

The phone is absolutely good, and everything works perfectly.

I ordered it on Rakuten. 16gb Ram 512gb memory.

You need to disable all lockscreen security or it can't get back into Android to complete the process, also removing your SIM is recommended

i tried again with lockscreen security off.

now, i can NOT read the IMEI and fail.

For the 1st try yesterday, it was able to read it. Strange. Maybe something broken now, but on the phone the imei appear.

[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] Dynamac:
Is this to flash to CHC and then back to BRI/TGY? Does 5G work on both sims and while both sims are active?

is 5G only on sim 2 by design or a bug, did 5G on sim 1 work before the may update?

Do you know if 5G is active on BRI now or when that may be expected? Similiar to my query above, what is the reason that 5G only works on sim2 and is there hope that will change?

Thanks!
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] lovers74:
No 5g did not work on sim 1 before the update, I believe its not bug. All Snapdragon devices act the same.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] brownie80:
I did intensive testing with logging tools as well. I am having the G9880 with latest July Patch installed, BRI-version, German Telekom SIM card (262-01).

SIM slot 1: no 5G, limited 4G band support only (bands 1, 3, 7, 8, 20, 28, 38), but carrier aggregation enabled

SIM slot 2: 5G with N78, N1 and N3 enabled (I added DSS support via carrier policy, but limited to B8 anchor for 5G N1, which is only a few percentage of the available 5G N1 towers), all 4G bands enabled provided by hardware - but NO carrier aggregation enabled.

VoLTE and VoWiFi working flawless as well.

Battery + overall performance is excellent, thanks to Snapdragon SOC.

Just I would love to enable carrier aggregation and B3, B8 and B20 as anchors for 5G N1 - then we are ready to rumble with this nice phone!

Anyone with ideas?
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] insomniacandroid:
What is the carrier aggregation? Is it useful? Does it work with exynos models?

I discovered that my phone is missing b32, but b20 should work.

I have s20+ snapdragon bri.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] brownie80:
Yes, B32 is not implemented (the antenna just may not be able to transmit on 1500 MHz) or licensed from Samsung for this phone.

Carrier Aggregation is the the "plus" behind your 4G logo in your display. It shows up when its activated and can accelerates the download and upload through adding additional bandwith of another or the same band.

For example: 20 MHz carrier at B3 band can be combined with another 10 MHz in B3 band. Or with 20 MHz in B7 band. Possible combinations can be different for different providers, phones, chipsets, modem-configurations and reception quality. Its even possible for upload.

In Germany you can reach more than 500 MBps through combination of bands 3+3+7+32 - with the Exynos S20 for example.

Check https://cacombos.com/device?model=SM-G988B for Exynos S20

Does your phone shows any "4G+" when your SIM is in the 2nd slot? Mine does not and it has serious impact on download speed.

Can you use 5G in both SIM slots now? And does it shows "4G+" for activated carrier aggregation? That would be very interesting to know.!

Oh wow - those speeds are amazing.

I'm in a 5G area for Vodafone but can only get 4g+ on both sim slots. Have the g9860 BRI changed to TGY using Samkey, so same as yourself I think.

Did you have 5G connection in sim 2 straight after changing to TGY?
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] bigup7:
I don't live in a 5g area so couldn't test before. I've always used Sim 1 and sd card though. 5g doesn't interest me right now.

I get 5g at work so can now finally see it.

I've done nothing else apart from use Sam key to change to TGY.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] shauno100:
Has anybody been able to successfully switch between CSC (BRI>TGY and vice versa) after recent firmware updates? it appears that since U2 bootloader is being used Samkey no longer works for changing the CSC. My SM-G9860 originally came with BRI (Taiwan) firmware. I managed to change the CSC to TGY but it was not via Samkey. I had to flash the Open China (CHC) version firmware via ODIN and then reflash back using TGY firmware. The CSC then became TGY as i suspect TGY is the default CSC but i have been unable to flash the CSC back to BRI when flashing BRI firmware. The CSC file looks identical in the firmware package.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] shauno100:
I'm also having the same issues others mentioned regarding the loss of 5G after One UI 2.5 update. It initially worked only on SIM 2, after the upgrade 5G is not working on either SIM slots now (I'm with Telstra in Australia) - annoying that Samsung keep changing things all the time, now i've got to decide between latest firmware with additional features + august 1 security patch or an older version where atleast 5G works (i.e. AP - G9860ZHU2ATFD)

I also changed from BRI to TGY several weeks ago using Samkey and now without 5G.... Its this a bug?? That should be fixed with next update?? How can you get around the issue?

I am also in same situation and with Telstra in AU but after UI 2.5... No 5G on any Sim.

Any progress on this issue? Am in same boat.. Paying for a 5G plan without 5G
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] shauno100:
If you really want the 5G (this is in reference to SM-G9860 model), you can flash back to TGY firmware (AP - G9860ZHU2ATFD i know works but some of the more recent One UI 2.1 based releases may still work) with ODIN, as for latest firmware we'll just have to wait and see what happens in future update(s) i guess, unless somebody else has found some way to get it working in latest firmware?

One other thing i should note if of interest to anybody is now that i am using the latest firmware it is impossible currently (as far as i know) to switch from CSC "TGY" back to "BRI" as Samsung have implemented some security feature to prevent this. Luckily if you're currently on BRI CSC and using a "U2" based bootloader you can still switch to TGY by flashing Open China (CHC) firmware in ODIN and then afterwards flashing back to TGY firmware which will set CSC to TGY as it's the default CSC in OZS.

Samkey have also advised latest firmwares no longer allow CSC changes. I tried flashing the earliest "U2" bootloader based firmware for TGY and i was unable to change CSC with Samkey "android SDK error" or something like that and with the latest firmware i got "AP version not supported) - also cannot go back to older firmwares with older bootloaders (e.g. U1) obviously.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] Mittesh:
Are you ever going to get 5g again?

Are we getting 5G again on TGY version or just give up with new version 2.5. I am not tech smart so can't make any of the fancy rollbacks etc
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] shauno100:
I can only speak of Telstra in Australia, but using latest firmware i cannot get 5G on either SIM. I've read others have reported 5G is now working on both SIM slots but i'm pretty sure they're not Australian users. But maybe this will be changed/fixed in a newer firmware, will have to see what happens.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] Mittesh:

[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] relax24:
Out of interest, why were people changing from BRI to tgy in the first place. I thought the Taiwan csc was better for UK people due to having carrier aggregation. What does tgy have over BRI?
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] cheetah2k:
Is this with the latest TGY August firmware? I just got a 200gb 5G mobile internet sim on telstra, ill try it tonight.

Have you tried the frequency / channel hack to force it on N78?
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] phrancini:
I'm from Italy, I get better carrier aggregation on TGY than on BRI, maybe our carriers use different bands. I can use Samsung pay with no issues and get spam protection with the caller id function.

Ah.. yep. No 5G on Telstra anymore :( :crying:
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] shauno100:
Yep unfortunately you'd have to roll back to an earlier One UI 2.1 firmware via ODIN. Hopefully though it might work again in a future release.

It is possible to flash BRI G9860 with CHC rom?

I am trying to get the native caller recorder and only CHC rom has it.

I have read samsung pass doesn't work on CHC, is that have a fix?
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] shauno100:
Yes you can flash CHC ROM with Odin on SM-G9860 with the BRI CSC. The SM-G9860 is identical (hardware wise) between TGY-BRI-CHC ---- no difference.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] bissa:
I have read to stay away from the CHC rom, and better to stay with BRI/TGY roms.

It is my first time to get the SD dual sim Samsung and I am little confusing as I have been always using Exynos OXM rom.

I am happy with the BRI rom but lacking the call recording which I had on the s20+ Exynos model is a problem for me and I tried all the recording apps and nothing worked like the native call recorder.

Any recommendation if I would face any issue with the CHC rom ? I don't care about the bands and 5G as it is not supported in my country.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] shauno100:
You asked if you could flash CHC ROM and i was advising that you could do that if you wished. Not too sure about the native call recording query you have unfortunately.

[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] brownie80:
Hi everyone!

I am back on 5G including carrier aggregation, working on both SIM trays with UI 2.5 and August Patch.

I never changed the CSC and did not rooted my G9880, but I did some serious surgery on my modem configuration.

Some facts:

- 5G N1 is working with 4G anchor band B8-only

- 5G N78 works with a bunch of 4G anchors, including B3

- 5G is enable for both SIM cards

I will provide more screenshots later, but this modem configuration is not something easy to do. Of course it will only persist until the next update, then most probably my modified nv-files will be overwritten.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] Mittesh:
That's awesome news... Looking forward to any guidance on how to do the changes.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] brownie80:
You would need to use QPST-Tools to upload a bunch of files into the EFS file system. It can break the modem firmware and leave the modem unable to boot properly, if you do something wrong.

But - I can confirm proper functionality, even if certain band combinations of the phone which are baked in the firmware cannot be overridden at the moment. Works for all S20 Snapdragon versions.

If you have your phone and QPST tools ready, and can access the EFS file system, let me know by DM and I will support.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] stefan243546:
Could I use qpst to add missing bands to my phone (SM-G9860)? My country is soon going to add more 5g bands and my phone only supports N78 from those that are going to be added.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] brownie80:
Which bands you are looking for?

The S20 Snapdragon variants from Asia have certain limitations in the modem firmware, which cannot be modified (at the moment).

For example, there are no carrier aggregation with LTE on B20, its only supported as single carrier. Look at the attached combos when used within the German Telekom network. In this case the network requested even B32, but not supported.

Also 5G ENDC NSA is limited to anchor band B8 with N1 only. It does support aggregation of B3 and B7 as well, but B8 must always exist as anchor band.

The following 5G bands are supported from the firmware: N1, N41, N78, N79 (there was N3 support before August Patchlevel)

4G bands implemented are: B1 - B5, B7 - 8, B12 - 13, B18 - B20, B25 - 26, B28, B34, B38 - B41 (there are hints that B66 is supported, but not confirmed)

No other bands can be used (at the moment).
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] X04D:
Would it be possible to export your modem and make it a flashable zip so others could use it? Or maybe an APK that applies your changes?
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] cheetah2k:
I second this

If you can provide the instructions to make the change, I'm keen to do it :good:
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] stefan243546:
My carrier, Orange, is the only carrier in Romania that fully supports my phone, such that I get 4G Carrier Aggregation, Volte and Vowifi (On other carriers like Vodafone I cannot get 4G CA to work) and 5G at the moment is also fully supported, as the only band used at the moment is N78. Starting next year, they will add N1 and N76 I think (will edit the post with the exact bands once I find exactly which are going to be implemented). That's why I asked, because starting next year I will not be able to get 5G CA with the supported bands of my phone. A friendbofine suggested that I use QPST, but I couldn't get the software to detect my phone, but I don't think I would have known how to "add" the bands anyway.

edit: these are the bands that will be added across all carriers starting next year: n12 / n14 / n83 / n20 / n75 / n76 and n7.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] insomniacandroid:
is it possible adding some new bands with a tool?

For istance my sm9860 doesn't support b32 and it would be good adding it.

So I am looking to get the n1 5G band working on my phone (G9860), but on TGY csc it cannot connect to it, possible due to my carrier using some different 4g anchor than the phone wants. I've done some digging and found that BRI on the other hand uses the same B3+B7 anchor for n1 as Orange, my carrier here in Romania. The problem is that when I changed my csc to BRI, I would not get any 5G at all. Here I have to mention that on TGY n78 band was working flawlessly. I have tried putting the sim card in the 2nd slot, but on TGY 5G has been working with the sim placed in either of the 2 slots ever since the one ui 2.5 update so that cannot be the cause. What could be the cause for this and is there anything I can do?
