The reason I asked is that I read somewhere that you can't 'downgrade' your firmware once you are already on the Sep 1 security patch. were you on the Aug 1 patch prior to downgrading to the July patch? I'm gonna try this on my Exynos phone, I hope it works as I am still on the Aug 1 sec patch. BTW I sent you a DM. I appreciate your time. Thanks!
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] tribalfs:
Not sure, but I think it will work with Exynos going back to Jul patch from Aug patch.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] BlinkThinks:
I will report here later.

Kindly check your private message. I asked you something about the firmware. I want to share with everyone if indeed I got it right. Thanks.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] jacktackle:
Was reading carefully but my question is

CSC changer can change borrowing exynos CSE on Snapdragon? I want to change KOR (KOO) to UK BTU.

Why? This will fix region problems and samsung daily will focus on UK news rather then korean.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] tribalfs:
I don't think it will work. Exynos and SD use different modem hardware.

You will have a good chance if from the same chipset.

IT works. Still after updating to the latest firmware (Ota), the 5g mark doesn't show up anymore. Still it seems I'm on 5g given my speed test. Did anyone else notice that?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] BlinkThinks:
@Tribalfs I want to thank you for this. Since your guide is for the SD version,

I made a thread for the Exynos version

[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] evenshop:
I confirm, 5g no longer works after OTA update even though csc is still BRI

Ows! That's absurd Samsung.

CORRECTION CORRECTION!

I am deeply Regretful if I am Derailing you guys with my Claim of Samkey being not a necessary Step.

Please allow me to explain.

I did try to Change CSC with Samkey. It Did the process and Resulted in Successful. But after the phone starts and I Checked the ADB info in samkey nothing was changed and also when I tried to check support from Samkey it said not supported. I checked *#1234# and the CSC version was OZS (TGY) not OZL (CHC). Also in software info it was TGY/TGY, TGY/TGY. So nothing was changed. And phone behavior was also similar. I spoke to ”phoneunlockservice.com” guys and told them for support, they check from their servers and said it is not supported and will not be refunding.

All above made me Assume it is not required to change CSC from SAMKEY but YES I did it initially.

My Mistake for not Quoting this drill.

Just added this up to ensure the community doesn't run into trouble. But this process is Real and Finally working.

Credit goes to [MENTION=1113385]chetbiz[/MENTION] who Tried it first and enlightened is. Big thanks to [MENTION=1113385]chetbiz[/MENTION].

I miss Samkey. :(
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] farehmani:
Hi [MENTION=1024633]fjorger[/MENTION],

My Software version now is CHC/CHC, CHC/TGY.

Call Recording is Active

Data Info in Notification Panel is also active.

Also a little change in 4G Placement. It is now with the Network Signal Bars.

Phone app crashing after CHC CSC Conversion.

[MENTION=1113385]chetbiz[/MENTION]

Please confirm if you are facing the same.

In the phone app I have noticed That the phone app crashes silently i.e. when in call log I tap on *contact* and then on *i - for Info* the the screen goes Black and then it comes back after two seconds. This happens everytime. Are you facing this issue as well.

Also I have noticed that any local contacts saved in international format does not picks up Save name from Contacts list. I have to remove the +92 from the phone number and then it recognises the name. Any workaround for this? As I have 2850 contacts and many are saved in international format.

Looking forward.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] chetbiz:
Yes it's goes black for me too, I don't use samsung phone so even didn't notice that.. also I have a problem with Samsung Theme, its asking to update but Its crashes and can't do update Themes Services
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] farehmani:
Same here
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] chetbiz:
I noticed that we couldn't update with Software Update in the phone, its telling that Your current software version isn't supported :(

---------- Post added at 08:38 AM ---------- Previous post was at 08:27 AM ----------

Interesting that when I enter the service menu *#*#27262826#*#* we have now option to change the CSC to WWD, from what I understand it could enable esim support, so it would be great if some one could try it, I don't have esim on my operator ...
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] farehmani:
Yea thats an issue too, but thisncan be manually updated whenever new major update comes. No?

This is because we made a hybrid ROM which is not officially released.

I am enjoying the clarity of recorded calls though. No major Glitches. Only the Contact Black Out.

So in short there is a cost of everything and for us it will be contact crashing, no updates and galaxy themes not updating.

Do you now what the CSC code WWD means? We have this option in *#*#27262826#*#*...
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] farehmani:
For WWD CSC, the only things modified are :

- Enable ESim Support

- Enable Menu block call
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] chetbiz:
That's I found too on google :)

Not sure it's relevant for our device..

Is there NATIVE CALL RECORDING feature in BRI and Samsung Pay works?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] fjorger:
As you may know, I have not yet made any changes to my default CSC (TGY) to the new "CHC" for call recording.

But while running the following commands (using Google Phone app):

- SERVICE MODE:

*#*#27663368378#*#*

- CSC SELECTION:

*#*#27262826#*#*

- BAND SELECTION:

*#*#2263#*#*

I Noticed that the CSC Selection shows only TGY and BRI, and Dev/QA.

Anyone knows what DEV/QA is for? Besides being the obvious "Development and Quality Assurance"?

Thanks.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] fjorger:
To to best of my knowledge, no. It does not have "Native Call Recording", don't know about Samsung Pay.

[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] farehmani:
TGY (Hong Kong)

It is more like international.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] :
Hi. Is it possible to take the modem file from one fir.ware and move it to another firmware and then flash it. I was browsing through the x55 folder in my firmware download and also in another variant and found xaa has all us and lot of other carrier bands where my tgy won't let me have 5g until nr41 it turned on in los angeles. I went deep into files looking and was wondering if I could edit or use different modem file then flash.

---------- Post added at 12:30 AM ---------- Previous post was at 12:26 AM ----------

I'm using s 9860 512gb bronze with tgy. I tried chc and every option but same bands. Could I use modem file from different firmware to flash. Thoughts? I even found in there all bands open. Every one the modem supports. That be nice. Or if we could get drivers and find way to unlock it. I want to root but I got brick. Anyone in los angeles would help me. I'm are master tech on cars. Trade car work for phone work
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Limeybastard:
Sounds like a good idea, I'm not nano savvy on the X55 apart from the basics. But how do we know if there isn't a few variants of the X55 that are used. One needs to check part numbers and such perhaps as a start.

I could be wrong , but during my time on XDA I don't think I've read about Qualcomm modems having additional bands enabled that never existed in the first place. We could start looking into this together.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] chetbiz:
Did you try to change CSC to WWD when you were on CHC rom? From what I understand WWD is a world wide rom, maybe there is some bands opens in that rom...
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] :
I'll flashback to check and try wwd, I thought only avail was tgy chc and bri for the 9860 , the xhc is full of bloatware like 2gb larger than bri.

I'm going to try to intermix firmware files and try it with unlocked bootloader. Idk. This is my first phone im trying this with.

I just want my 5g to work. T mobile bought sprint to gain nr41 which I support but I cannot find anywhere in los angeles with it working. So I'm trying to add nr71 nr66 , I don't care about mmwave , but on my 986u1 I just mailed back to Sammy saying my esim isn't working. I'll send it weekly if I have to. Lol. I got 1yr warranty and Sammy care so ill do it for long time. I'm not waiting for the future update to enable it. So just to be clear. I'm trying to crack modem on 9869 for 5g and crack esim on 986u1 for dsds. Yall have great day.

Oh lastly. Do the people that say they can unlock bootloader on 986u1 ,can they do it or is use a scam?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] farehmani:
Idea from WWD if it is World Wide Rom. If Changed to WWD then It may remove the Chinese formating and small changes like Web pages opening to .com instead of. cn and maybe othe little Chinese stuff gets removed. Us the call recording stays. Who knows.

Has anyone tried WWD

Call recording feature is so good that other problems are forgotten for now but in the longer run if you imagine no updates. That'll be a problem. Because of the mixed ROM we have made now.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] fjorger:
Yeah, I agree 100%, maybe WWD is the a solution.

As you mentioned, the big problem with the mixed/Frankenstein TGY/CHC rom “Native Call Recording“ solution, is indeed the inability to get any kind of official OTA update.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] west2cool:
To get official update he has to flash the full CHC firmware. What I did was to change CSC from TGY to CHC using samkey then flash the full CHC firmware using AP, BL. CP and CSC (please note I did not use CSC home). Once I setup the phone I checked for a software update and was able to download and install. I didn't like the software so I have since changed back to TGY by changing CSC to TGY and flashing a full TGY firmware.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] fjorger:
I Think while using the “mixed“ solution we would want to get OTA updates from the Native TGY, not CHC. But that would mean spending more Samkey credits just for the CSC change (from CHC to TGY and then back to CHC after the update).

Not something we wanna do every month or so.

Well, although with no other (worry free) solutions to “Native Call Recording“ problem as the existing Mix TGY rom/CHC CSC, with the resulting OTA issue, I would still prefer the halfway ACR solution (even with the low quality and no Bluetooth).

But that's only my opinion...

Nonetheless we are going in the right direction (thanks to our relentless users ”chetbiz“, ”farehman” , “tribalfs“ and many others).
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dalle3:
You didn't need to use samkey to change csc to CHC,

it's another partition size flashing full rom with csc

not csc_home works and updates too and when you want to go back to tgy same proces reversed.

Samkey only needed to change between bri and tgy.

Been using this way with s10+, s20+, ultra and now with note without any problems
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] chetbiz:
What you mean you dont need to use SamKEY, I was on TGY and tried to flash CSC CHC file (not home_csc) and got an error in odin,

only after I changed CSC from TGY to CHC with SamKEY I could flash the CSC file of CHC without a problem...
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dalle3:
Full flash with odin bl, ap, cp, csc

done at all my phones from hk without any error and vice versa to tgy
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] chetbiz:
Ok this is understood and of course its works I tried it too because you flash the CHC rom from scratch. But whole the point is to end up with Rom CHC,CHC/CHC,TGY, because only then you have integrated google services from TGY rom and the only way to do it is when you on TGY rom to flash only CHC csc file and that can be done only after you change CSC to CHC with SamKEY when you on TGY rom and after that flashing only the CHC csc file.

[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] chetbiz:
I was on clean CHC rom, not everything works, google assistant doesn't work, and its different when you install google apk or its integrated like system app...
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dalle3:
I don't use google assistant at all, and for apk its same thing if you installed it as user or was already there as system priv app

I'm completely ok with this csc
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] chetbiz:
And I use google assistant a lot and there's some programs that's uses google assistant for their language recognition system.. so its very depends on your personal use )

What's different from CHC?!
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] chetbiz:
Didn't found yet, only that the phone app doesn't crash when I open contacts from recent call log..
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] farehmani:
Yes of course,

Have you full flashed CHC ROM and THEN Converted CSC to WWD or Changed TO WWD in your current Mixed ROM? That must have the option to update itself as it'll be a full original ROM.

Preferable it must have been tested on Full Flashed CHC ROM that it allows Google in Or Not. And that Call Recording is still intact.

Also If you converted to WWD on your TGY ROM then is it CHC/CHC, CHC/TGY? Still or something else.

Is call recording still present?

Does it allows updates. (It must not)

Does the update theme message gone?

Is the data usage in notification panel still there.?

Does the caller ID saved names working properly.... I mean the number format and caller name display problem (sometimes show number instead of name even if number is saved.)

What else have you noticed in the ROM?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] fjorger:
Great news.

Thanks chetbiz.

What about Samsung pass, and Themes?

If they both work on CSC WWD, then the only drawback: OTA updates.

Well: never mind, I can see someone already asked about it (minus Samsung Pass)...

Guys I need your HELP! With all this rom flashing I soft brik my phone, forgot to remove google account :crying: and now I cant flash any rom, its saying FRP lock enabled...

The factory reset with recovery doesn't help, probebly because of a combination of chc csc file and TGY rom. I`m stuck

Form what I read I need to remove the FRP lock, but for this I need to flash combination file for our device, don't know where to get it :crying::crying::crying::crying:
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] fjorger:
Dam, that's really bad.

Did you already tried the steps described here https://technastic.com/remove-frp-samsung-combination-file/amp/ ?

What did you get? Response?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] chetbiz:
I tried that but I cant to extract the AP and BL files, they all have a passwords:(

Maybe there are files without password???

I already got the combination file for our phone but I cant flash it because I need a PIT file, and I cant extract it from CSC file because its too have a password (((
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] fjorger:
Hi again,

I'm using SamFirm tool 1.3.0 , and I see that it has (Samsung tab) the option “Bypass FRP (MPT)” . Although ”fortunately” I never tried it, there is a newer version “in the next few days” (1.3.1), using a new FRP method.

Did you try it?

About the password, it's very strange, there are no passwords whatsoever, at least on the ROM I downloaded (ATI3) , I'm now downloading the latest TGY (BTJ9), just to see if they are different and replicate what you are saying (but I do not believe they are), nonetheless my question;

What tool did you use to grab the Firmware that you currently have? I'm guessing it's not SamFirm tool, right?

Because the tool downloads and decrypt's the file automatically...

PS: I know it's already too late, but while downloading the latest odin, the first popup window “Please be sure to delete your Google account (Samsung account) before....“.

[emoji3062][emoji3063]
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] chetbiz:
Didn't try the Samfirm tool, will try ot tomorrow.

About the files I mean when I try to rename AP file and to add zip extension lile they sad, after this I can't extract that file, i didnt mean about the whole rom zip file that contains 4 files in it...

About google account yeah I know I really f*** UP. It was realy stupid of me (( I hope I could bring this phone to life (((

Thank you very much for your support..
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] fjorger:
No problem, you are welcome [emoji4].

Just trying to help you out (you would do the same for sure, for any of us) especially on a ”more than1000” bucks phone.

And on top of all, you have been risking it, trying to give us a valid solution for the “Native Call Recording” problem.

And you did found one...

About the Google/ Samsung account deletions before any major firmware (using odin), I have been there ”4 years ago” (Note4 N9100), so don't punish yourself (we have all done some kind of “stupid mistakes“ at least once).

About the “ZIP” rename, try to open the resulting “renamed“ file with the latest 7zip or Winrar, instead of Windows Native zip support.

And don't give up just yet (I think you will recover the valuable Note 20 Ultra still) , fingers crossed [emoji1696].

Keep us posted.

PS: update: I just finished BTJ9, and I was able to open/extract all files inside (AP and BL), no Password [emoji848]
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] chetbiz:
I successfully opened the files with 7zip, strange with winrar its asked me for a password..)

Unfortunately the process with combination file and pit file didn't work, its still saying FRP enabled, ignore PIT download :crying::crying:

About SamFirm I didn't found version 1.3.0 and on other versions there is no Samsung tab..
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] fjorger:
Hi,

About Samfirm 1.3.0 and ”Bypass FRP“ feature.

Just type in YouTube.com and then add

/watch?v=4Nwe-QKTx-4

Go to “Mahmoud Salah“ Comments page section, and search for the 1.3.0 download link.

Remember that you need a “patched“ version of “odin“ for the ”special” combination file to be accepted.

Just wondering, were you able to locate all files mentioned for “combination file build”? I mean what files did you add (total of 3, right?)?

Mostly, did you find “shoot.bin.*“ ? Because I couldn't !

Keep us posted.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] chetbiz:
I downloaded ready combination file here - https://www.fullstockfirmwaredownload.com/downloads/combination-sm-n9860/

The whole problem is that Factory Reset doesn't work and I cant startup the system to get to enter google credentials and remove the FRP lock, something went wrong because of TGY rom and CHC csc and with FRP lock I cant reflash anything at all including combination file. There some solutions with z3x-team box that's opens frp lock, but you have to buy box like this and I don't know even if our device supported.

This guys have some solution for FRP unlock too but for SM-N985F/DS device, I will try to ask them if they can make for our model... https://www.fullstockfirmwaredownload.com/downloads/frp-bypass-sm-n985f/
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] fjorger:
I know the mixed TGY/CHC doesn't help. [emoji855]

You mean, you had to pay for the combination file, because I searched everywhere for a 9860 combination file, and found none (I read that we could create one ourselves, but never tried it).

Did you try the Samfirm “Bypass FRP (MPT)“ new feature?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] chetbiz:
Yes I payed for this combination file, its the only place I found one for our device...

The Samfirm Bypass FRP (MTP) solution will not work because you need to boot to system for MTP to work, its an APK that they install and try to unlock, If I just could to boot the device all problems will gone any way because I could remove FRP by enter my google acoount...

Csc change

I did the atgm firmware with chc and I was able to go into service menu of google phone set my csc to tmb,xaa and xas and all north American carriers and I got my 5g working and call recording. There's ton of bloatware to remove and few quirks that it has but my 5g button now toggles 5g on and off , I got 648mbps speedtest. I haven't figured out how to upload photos. I would do screen shot but it asks for url of my photo when. I try to upload. But I was successful. I have 5g on 9860. Whoop whoop

Next I'm still trying to get my esim working, I send my 986u1 xaa in for service last week , I made service tag because my esim was broken. I will send it every week until they turn it on. 1 year warranty plus Sammy care plus.....its their money their spending on ups for shipping. I figure it be cheaper for them to turn it on than every one who owns one to ship it in for warranty claim saying its broken
