Hi,

First time venturing into firmware flashing. Appreciate all advice I can get from experts here. Many thanks in advance.

I'm planning to flash my Note 20 Ultra Taiwan firmware (BRI) to HK firmware (TGY).

I realized Taiwan and HK shared the same CSC on Sammobile. So, can I still flash to HK firmware (TGY)? I have downloaded Odin V3.14.4.

Next question is, Samsung pay works but I do not get Samsung pay rewards for using Samsung pay. Since I'm flashing the firmware, is there any way I can make Samsung pay reward work in my country? I understand I need to change the CSC code.. Do I use XSP (unbranded) in order to be able to use all the telco services in my country (Singapore)? I was told that HK and Taiwan set uses single CSC, what does it mean?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] MrPhilo:
Did you flash anything else to make it more UK compatible like another CSC?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] tdodd:
I have not flashed anything except the official OTA updates. Mostly everything works to my satisfaction with the following minor or irrelevant negatives....

- Samsung Pay won't work with a UK bank card, but I don't care as I've always used Google Pay.

- For LTE the phone is missing Band 32, used by Vodafone and Three, but seemingly only in city centres where I seldom venture, so no loss.

- 5G definitely works with Three. With Vodafone it's a little unclear. I've seen the 5G symbol, but using nPerf to map out coverage it does not recognise a 5G signal from Vodafone, whereas it does with Three. All posts I've seen say that 5G does not work with EE, but I have no personal data as I don't have a 5G SIM card for EE or O2. Almost nobody comments about O2 5G.

- VoLTE and VoWiFi (Wi-Fi calling) both work if the SIM supports it.

- When 5G does work, you can only select one of the two SIM cards to be on 5G.

I'm not really concerned about 5G, but the techy in me is curious to see what works and what doesn't. Living out of town it's pretty much irrelevant for me. I have to travel out of my way to find a 5G signal for testing.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] MrPhilo:
I see, I was also looking to purchase it from t dimension. Hopefully I get the Hong Kong version not the Taiwan.

Have you ever got an update without having to flash it manually?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] tdodd:
Yes. They've been the standard OTA updates, obtained through the normal software update dialogue screen. I have not "flashed" anything using ODIN or anything like that. It's 100% standard Samsung stuff.

I'm trying to attatch a screen print from the phone of the software status, but this stupid forum refuses to display the image. I've tried four times and it will not display. I've seen this a lot lately with other people. Sorry I can't show you how it looks.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] chetbiz:
Most important don't forget to delete your google&samsung accounts and remove screen lock before reflashing )
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] micshang:
Thank u for your advice.

Delete Google and Samsung accounts, I remove these 2 accounts under accounts and backup in the phone?

Remove screen lock, I select none under screen lock type?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] chetbiz:
yes you must to do it, I didnt do it ones and now I have a brick phone and I can't even reflash firmware..
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] micshang:
Thank you.

OMG! That is bad! Can u bring it to Samsung service centre? I'm sure they can do something about it? Like, re-install the original firmware?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] chetbiz:
unfortunately I cant because I bought it on ebay from Hong Kong, I asked samsung service in my country and they told me they dont support this model because its not even for sale here and they support only exynos models
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] micshang:
How about sending it back to the seller that u bought from on eBay?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] chetbiz:
yes you must to do it, I didnt do it ones and now I have a brick phone and I can't even reflash firmware..

Tried to contact him, he doesn't respond to my massages, I think the only option for now if I find someone in Hong Kong that could help.. or to wait that z3x box, octopus box will support frp unlock so than I could do it by my self..
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] tribalfs:
For curiosity's sake, I tried full CHC room and changed to WWD . Here are my observations.

5GNR (1 ,3, 28, 41, 78 and 79) and LTE Bands are the same as TGY

OTA update does not work

Phone app:

- call recording is enabled

- call blocklist and whitelist is enabled

- spam call protection is missing

- Nearby Places tab missing - replaced by Chinese exclusive Yellow Pages tab which you can't totally get rid of.

Samsung Pay app installed but stuck at splash screen

Samsung Pass is missing.

Secure Folder is missing. However there's a stock individual App Locker which I think is better than Secure Folder

Samsung Members app not supported

Google Play is missing but can be sideloaded

- Software is google certified. Passes safetynet. So, my bank apps work

- Data usage stat in notification

Smart Manager in place of Device Care. Includes Autorun apps settings

Only two (2) CSC options in CSC change settings - CHC and WWD
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] chetbiz:
Guys from what I understand to unlock frp I need binery 4 unlock frp file, its an special AP file that you can flash and it's removes the frp lock, the question now where to get this file for our model..?

Do you still get the chinese keyboard or the normal keyboard?

Also can you try keys cafe?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] tribalfs:
Yes same keyboard
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] farehmani:
New Thought!!!

Please share all your opinions and ideas.

Side Note. (@chetbiz I feel for you man. I hope your phone is up again asap)

I'm thinking of selling off my N9860 and buy an Exynos N986B/DS. It serves everything I want

*DUAL Physical SIMs

*5G

*12 GB Ram (Since my country officially offers a ****ty N985F 8 GB Ram Version)

*Will Change CSC to Either INS (India) or THL(Thailand). Both CSCs supports Native Call Recording. Don't know if Data Usage Info is there or not.?

*Will keep getting official updates every time.

*will have Samsung Pass

*No compromise on Google Services and Apps.

So It serves all the purposes. I checked a N986B/DS of a friend of mine at my Gym today. Dialed *#*#27262826#*#* on Google Phone app and it had a huge list of CSCs to change to. I'm so wanting to replace My Snapdragon to Exynos now.

Ive seen on YouTube the performance difference is very minor. Everything else is ditto.

What do you guys suggest.

Please advise.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] destz0r:
Performance difference is minor, agreed. But battery difference is pretty significant imo. The battery is the only reason i went for snapdragon version instead of exynos.

So if you dont mind having a bit worse battery life, go for the exynos then ;)
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] -cyNix-:
Same stupid china region keyboard? With the weird 123 button?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] farehmani:
I've tested battery and difference is huge. So I'd rather stay with Snapdragon. Also performance is also way better 16%.

Not the least. Exynos heats up too and deceases performance further.

Hi [MENTION=1113385]chetbiz[/MENTION] did your phone come back to life?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] chetbiz:
Unfortunately no, still bricked. No solution for now
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] -cyNix-:
PIT is just the partition information table right? Can you just flash the AP so that you can boot the device? Wondering if you have your own thread somewhere of how you came across the brick? Can you flash anything other than PIT at this point?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] chetbiz:
I cant flash the AP file, ot always failes and stops on super.img, I get an error on phone: FRP lock enabled: cant write PIT file. I told here all the story about how I got to this situation. Yes I can flash everything besides super.img file and 3 files in CSC dont remember their names but from CSC I can flash only cash file. This I know because I tried to flash with chimera with the filter option.

[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Giang gau:
Can u help me
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dalle3:
Hi, i used this one without any error , remove first your google or samsung account from phone , then use

all files and CSC_OMC_OZL_N9860OZL1 not HOME_CSC_OMC_OZL , same odin ver have used with g9860 ,g9880

from tgy to chc ,and back to tgy before sale no errors
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] juston80:
This method worked perfectly.

As soon as I entered the code, I saw the whole list of CSCs that I didn't see before even with Phone INFO ★ SAM ★ Plus.

So I was able to select THL thus enabling native call recording as well.

Thanks a lot for the news

:love:

Hello! I am on latest december ORX firmware update (manually flashed) but phone is still TMS, even when there is no december update for TMS (I know this way I could not change CSC). I'v tried google phone app way and I see only few CSC:

COS, CRO, DTM, MAX, TMH, TMS, TMZ, TNL, TPL and dev/qa option.

Am I doing something wrong?

Others have more CSC's on exynos phones right?

N986B/DS

I am facing issue with no 5G on this combination, even when it should be working for both, ORX and TMS...

Hello,

I have buy a Galaxy S20+ but I'm really annoyed with it :(

It's the SM-G9860 Taiwan version (BRI). I have right now the G9860ZHU2CTL3 Firmware (I'm in France).

The problem is, Free has activate 5G and everything is ok with my xperia 1 II but, with the s20+ I can't have 5g connectivity ;(

I saw some of you had same issues and solved it by downgrading the firmware, does it wipe all datas ?

If I'm understand correctly I only have two solution as we can't actually change CRC to XEF : change it to TGY for HK location or downgrade it ? I prefer to not install the CHC version.

It's for a friend and I don't want to loose phone datas, I can flash with Odin only HomeCRC no ?

I also see the way with Phone Call App by Google, I see I can change to TGY on my phone, is it ok if I select it or should I backup as it will wipe everything ?

Thanks for your answer, it's the first Samsung phone I buy and I think it will be the last one ^^

Hi there,

I bought a Korean note 20 ultra snapdragon and i leave in Israel, where there is only the enoxios version. Can change my csc N9860ZSU1BTK3 (again, a snapdragon) to israels enoxios csc?

2 reasons i would like to change:

1) because Israel is the only place that call recording is allowed, and that feature is very important to me.

2)till this very moment, i didn't receive the 3.0 update for my Korean N9860ZSU1BTK3 csc.

In other words, i need some help guys 🙏

Thanks in advance
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] jirka607:
N9860 is not Korean version, Its HK/China/Taiwan.

Korean version is N986N and no you can´t change CSC to exynos version
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] jirka607:
so i bought N9860 BRI version and LTE+ and VoLTE works immediately with speeds around 150mbit/s so everything is fine

Only at home where i got LTE+ on exynos version i have only LTE

I guess no point in trying TGY? Or will i gain something?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] shinsplit24701:
Thank you mate🙂

[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Mooatreides:
same here, i have vowifi and volte on partner, no5g yet.

any point to change from tgy to chc just for android 11, call recording and network speed? Will i have full English french and hebrew? or a hastle for nothing?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] fjorger:
There are a lot of feedback posts about the CHC rom issues (if you are okay living with all the nags and troubles) go ahead.

I will not. Although I do miss the ”call recording” feature a lot, I have to live with a crippled features of the only working ACR software (and cannot record when using Bluetooth device, example : Car), other than that, all good with the TGY rom so far...

PS: by the way, I got Android 11 One UI 3.0 today 😇.

About 5G support, unfortunately Portugal is lagging behind (no comercial 5G implementation yet), and due to Covid19, no travel to test it elsewhere...

If You have possibility to enter TGY, You can choose TGY...but on my phone, if I put any firmware, nothing happens with CSC code ;-( and nothing to posibility to change /of course, after downgrade to Android 10/

BTW: But I solved problem before two days, I have found one Czech service guy, who is serviceman in Samsung. he has changed for me CSC code, but I must visit him and took phone to him.

Now is clear with possibility to change to all versions ;-)

He did this over some Samsung BOX for repairs and authorized sellers...I gave phone to him, waited 20mins before building, after that, he brings me with chnaged CSC and with possibility to change to whole world.

1. By only flashing csc from CHC to TGY will samsung pass, pay, and secure folder and also Google services and apps will works as before as on TGY?

2. Or after flashing chc from tgy and changing csc from chc to wwd will the services works as asked above?

I didn't use Samkey. On Android 10 TGY I flashed Android 10 CHC then changed csc to wwd. Once changed I flashed Android 11 CHC via ODIN using home csc.

You won't get any OTA after that and you will have to manually update everytime
