Looking stock firmware for SM-R805F

Hi everyone,
I just recently got a SM-R805N (Korea LTE ver) and want to change its region.
However the CSC variants in the stock only contains Korea telecom (as mentioned in the CSC thread by ecoco1)
I am trying to use the old fashion way: flash in the combination firmware, switch the CSC and then flash back to stock, in which, the CSC I am looking for is in SM-R805F version
However, I cannot find any free source for SM-R805F firmware online... all those available , also in this XDA forum, is only for bluetooth version.
Would anyone in XDA able to source the R805F firmware? (best to have both combination & stock?)
Thanks a million

Caution.
Since Gear S3 it is NO good idea to flash wrong Firmware nor wrong parts... to LTE variants...
You could end like this:

https://forum.xda-developers.com/smartwatch/gear-s3/please-help-bricked-gear-s3-sm-r765s-t3665558
I have no Galaxy Watch... but this means not I have no idea how dangerous it is... if you doing """experiments"""...
Example:
https://forum.xda-developers.com/showpost.php?p=78545468&postcount=74
Only as info.
Additional info...
Not tested what happens with CSC only... BUT be sure it is not less dangerous... because partition PIT is inside CSC and netOdin AUTOMATIC write this file to device...
Suggestion...
Study offline...
You can extract files with 7zip and compare...
rootfs.img needs some other Tools or Linux... or...

Thanks adfree, but its too late... I have already bricked my brand new galaxy watch...
Now the watch wont go into any mode below. All it does is have a flash of horizontally line screen, consistently.
continue
factory command
recovery
download (wireless)
Tried the method "press 2 seconds, release 1 second" does not work, think it corrupted the partition.
Only mode still work is "download" which shows the screen correctly. What make it worse is I reset the watch before doing this and forget to turn off activation lock (but I have my own user name and password, think that does not make it worse then?)
Appreciate if any idea on how to tackle this... am already thinking about buying the usb connector for odin flash...(hopefully something will make it work again...)

Suggestion, if you want try it self at home....
Look into this post:
https://forum.xda-developers.com/showpost.php?p=78545468&postcount=74
Look into Video...
You can also click around this Thread... to see diffferent "solutions"...
Security prevent netOdin use... IMHO no way without USB to flash again.
If you have POGO Connector... Odin...
Then try FIRST to flash SM-R805N...
I see at this time it is not leaked...
So you need luck to flash SM-R805N Firmware...
Hopefully Warranty Void will still:
0 0x0000
Seems 3 SM-R805N Stock Firmware leaked:
Code:
R805NKOU1ARK8
R805NKOU1ARJ6
R805NKOU1ARHJ
You can PM me... if you need Help with POGO...
Best Regards

Sent you a pm thanks very much, i have not yet able to watch the video as im at work, but i think i need the items below:
R805N stock firmware
POGO Cable for usb connection
anything else would i need?

Thank you @deadman96385 for the firmware
Hi adfree, here is the photo of the "Download" screen
Now i need to get my hand on the cable to try it out...

Thanx for Photo. :good:
Good:
A
SM-R805N to see...
So sboot.bin is not overwritten...
B
Warranty void still 0 0x0000
So Knox not dripped... BUT you have to wait for final result after Repair Flash...
Not so good = IMHO bad...
Reactivation Lock is ON...
This means MORE f&%ing Security...
As "we" have only Stock Firmware...
If no luck then also Warranty Void Value will change... maybe.
P.S...
partition.pit aka PIT is 1:1 same between SM-R805F and SM-R805N... except the RSA 2048 Signature crap at the end of file.
Best Regards

thanks... I should be able to get the POGO wire mid next week, will update you the result....!

My Galaxy is back alive! Thanks everyone in this thread. Tested the following:
Install R805N firmware: Download mode: Works
Install R805F firmware:
Download mode: PIT fail instantly, without install
Download (Wireless): Able to complete the install -> Fail warning in red -> Bricked
Tried for combination firmware, or CSC only, same result
Guess I will never have chance to change my CSC then...? (Unless there is a combination R805N available which has all CSC countries inside?)

no i am not able to change, as mentioned above, the original firmware does not have other CSC included, flashing any other firmware will brick the watch

G975U and G975U1 Firmware Links and Flashing Discussion Here

For those who aren't already aware, G975U is the model number of all of the US carrier versions of the S10+. The G975U1 is the model number of the same device, but sold by Samsung SIM unlocked and with no carrier bloatware. Firmware is 100% interchangeable among these models: any U or U1 firmware version can be flashed to any U or U1 device at any time, assuming that you're not trying to downgrade the bootloader. A "U to U" or "U1 to U1" flash does not require a factory reset, but changing from one firmware to the other will require one. Also, U firmware is identical for the 4 base files (AP, BL, CP, CSC) for each individual build, no matter which carrier it comes from. So if you download 2 different carrier versions of the exact same build, the 4 base files will be identical. Where the firmware differs is in the USERDATA file - that's where the carrier bloatware and customizations reside.
Manual Odin flashing is designed for those who:
- want to manually update to a newer version of U firmware on their U device, either because they don't want to wait for their carrier's OTA or because OTAs aren't working on their device, or a different carrier got a new feature/patch before they did
- want to flash U1 firmware to their U device
- want to convert from U1 firmware to carrier U firmware
- want to convert from one carrier's U firmware (with all apps and bloatware) to a different carrier's U firmware (with all apps and bloatware)
For those who aren't already aware, anyone can now download firmware for almost any Samsung device any time that they want, via the various firmware download tools posted here on XDA like SamFirm or Frija. There are threads and info about them here on XDA so I won't waste time explaining - do a search if you're not already familiar with these tools. But they only provide whatever the latest/newest/current version is - nothing older. I pay for a subscription to a site that gets the official releases (usually) before they hit the firmware download tools, so that's where my files come from.
This is not a "beginner's guide to Odin flashing" -type post/thread, so I won't list basic, step-by-step flashing instructions. My threads are geared towards those who already know what they're doing. If you're new to manually flashing Samsung firmware (or haven't done it in a long time), I recommend you consult one of those "beginner's" guides- there are tons of them here on XDA.
Happy flashing!
U firmware: https://www.androidfilehost.com/?w=files&flid=290649
U1 firmware: https://www.androidfilehost.com/?w=files&flid=290650
Notes:
- I compress extra small for space and bandwith savings. The default Windows extractor can't handle it, so you'll need a 3rd party tool like 7zip, WinRAR, etc
- I remove the .md5 from each file solely for faster flashing (Odin won't check the file integrity without it). Rest assured, the files are perfectly fine and safe - Odin has a million safechecks built in.
- My naming method for folders is: build - bootloader - Android version
So "SAT - 1 - 9.0" means the full build number ends in SAT, it's bootloader version 1, and it's Android 9.0. When bootloader and Android versions increment, the first build to have those changes will have its folder notated appropriately.
- HOME CSC file keeps data intact; using the other CSC will wipe data. Any zips with "wipe" in the title do not have a HOME CSC included.
- I have identical threads for the S10e and S10 as well
- the correct procedure for switching from one carrier's firmware to another is given in post #25
- You can get USERDATAs from SamFirm for everything but AT&T and Cricket- those files will never be on SamFirm. So in addition to the 5 piece firmware, I'll try to always upload one USERDATA per bootloader increment for those carriers.
- For identifying USERDATAS, and to know what region/CSC to use in the firmware download tools if you're downloading yourself:
AIO = Cricket (not available via firmware download tools)
ATT = AT&T (not available via firmware download tools)
BST = Boost Mobile
CCT = Xfinity Mobile (Comcast)
CHA = Spectrum Mobile (Charter)
SPR = Sprint
TMB = T-Mobile
TMK = Metro PCS
USC = US Cellular
VZW = Verizon
XAA = U1 firmware

This is looking great, was about to pre-order the T Mobile variant, when I remembered that they disable the (Data) Quick Toggle and I have to fiddle around to turn it off, Well, Not the case with the Unlocked version, at least on my Note 9. Anyways, this will come in handy, thanks!

Hopefully One UI stays the same. You're welcome

Good to see and will be a good place to hangout! ?

Loved your dedication to uploads on the 9+! Glad to see you here as well! I preodered my ATT 10+ yesterday. Got my mom and two daughters the 10+ / 10e also. Happy to see you'll be providing firmware for the "E" also!

Build SBA added.
Only CCT, VZW, and SPR USERDTAs (for now), but it can be flashed to any S10+

So I flashed this on my new U1 and went to U firmware. My Wifi didn't work after this. I can't connect to any Wifi network... I will try going back to U1 and see if the issue is fixed. Maybe I have a defective phone?

Hmmm that's weird. I'm assuming you wiped?

G975U and G975U1 firmware is now live and downloadable in SamFirm. Getting U1 requires manual entry - Auto will not work. U firmware is up for these carriers:
Xfinity Mobile
Spectrum Mobile
Sprint
T-Mobile
US Cellular
Verizon (have to use Manual entry - Auto will not work)
So going forward, I'll only be adding full builds if I can get them before they hit SamFirm, and only if there isn't build for that month already (eg. I won't add any more February builds since SBA is already up.). I will try to stay up to date on USERDATAs for AT&T and Cricket, since AT&T won't let their firmware be put on SamFirm.

Thank you for this. Just flashed my U1 to TMB SBA for video calling feature.

I have a question and I hope someone can help me. I just purchased a s10 not the plus. And its unlocked which is great but has three UK branding on boot up ect..,
Is it possible to remove this maybe install another rom via oden? And it wouldn't void warranty or enable a security problem on the phone? Any help would be much appreciated

Guessing ATT is late to the party as usual with no ASAB userdata yet? Doesn't appear they've pushed it yet ?

Anyone can flash any update - USERDATA isn't required unless you're changing from U1 to U, or from one carrier to another.

Ah ok. On my S9+ I did some Odin flashing and even though I was on the att release, I wasn't getting OTA's. It was odd. Only way to restore OTA updates was flashing with ATT userdata.
On a side note, ATT has pushed the ASAB update for both the S10+ and the S10E.

Is it safe to flash A505F firmware on the A505FN device? As far as I know, the only difference is NFC.
And is it possible to void the warranty by doing this?
I tried Smart Switch a few times, but no updates.

Hi thanks for your reply.
Should I need to remove all accounts, and make a factory reset first?

Smart Switch only will provide you the newest firmware in the same line, not an option to use other different firmware from a different region.
Ever is recommended to do a factory reset/format data before to "switch" to other firmware and make a backup before to restore it in just minutes with SS.
Install Phone Info(Samsung) and there you will find the CSC availables for your device before to change the firmware (most of the international models are multi_CSC compatible), search for the regions and compare them here https://www.****************/2017/0...specific-product-code-csc-and-country-region/ if some of them is convenient for you then you can flash it, check before your bootloader version, I think all are now in v1 but check it before to go further.

Yes, you usually can (I switched a lot of times) but you could find some issues regarding to radio/baseband depending on how different they´re.
Take a backup before using Smart Switch, take note of your actual firmware in a safe place if something goes wrong and don´t forget to enable USB debugging and OEM unlock before to go.

Hi,
Good yes already did a backup and OEM Unlock and USB Debugging are one.
I'm simply waiting the firmware to be downloaded. Take very long time to download from samfrew

Finally succeeded in flashing to INS.
I forgotten to remove my Sim Card but even that it has changed the CSC.

Hey, what's the model of your device? Is it FN, or F? Because Indian firmware is A505F, so I don't know if I can flash A505F firmware on my FN device.

My model is A505F. I don't think you may install F on FN. It may work but you may have several problem with correct functionality of the phone or even brick it.

F firmware on an FN device should be ok afaik, but I believe you'll loose NFC
Also keep in mind that INS csc has this string in cscfeature_network.xml
<CscFeature_Message_ConfigImeiTracker>+919560345888,+918424098931,+919176905802</CscFeature_Message_ConfigImeiTracker>
I remember that this was a problem on custom roms for the old A-series since all roms for some reason added INS csc, so a bunch of users in europe got charged extra for messages to india if they didn't remove that from cscfeatures..
Not sure if it still acts the same, but I can confirm that the string is there in INS csc for A50.

Thank you.
There is finally firmware with July patch for FN versions of this device, so probably I'll wait few days, because only 5 countries in Europe got an update to the newest version, skipping June security patch, but I hope we'll have new features in the camera.

Change CSC on N975W

Does anyone know how to correctly change CSC on the Canadian N975W? I purchased a used Note 10+ that the previous user bought from Samsung direct but had a Bell sim so the CSC shows BMC and has bell bloatware. I'm trying to change it to KDO but no luck with any firmwares yet. Any ideas or steps I'm missing?
Tried both KDO and XAC firmware but the file names seem that they're the exact same from both updato and SamFirm.
Using patched odin and everything loads fine - using CSC not the Home CSC.

it should change depending on sim inserted as long as it contains the csc on the device.
you can use phone info or similar to see available csc.
you can also try *#272*IMEI#
Domt think itll help but i believe you could also install U and U1 firmwares to ur W variant. Maybe trying the U1 will help

Only in the same muti-csc rom can change
Go to http://www.samkey.org/ to buy SamKey CodeReader – 15 points is $ 45 USD, and there are split sales on some trading platforms for about 3 points $ 6.6 This is what you want to do
Download the SamKey program on its website, and download the driver together if necessary

Go to http://www.samkey.org/ to buy SamKey CodeReader – 15 points is $ 45 USD, and there are split sales on some trading platforms for about 3 points $ 6.6 This is what you want to do
Download the SamKey program on its website, and download the driver together if necessary

SM-G9880 Flashing Question

I recently just bought a S20 Ultra that has a unlockable bootloader. A little while back, I had a Galaxy S9 that I could completely convert the entire device to U1. Is that even possible with this device ? To fully convert the CSC and bootloader ect, to a US model ?

That was then. Each model is specific to a region and can not be flash with software from another region. I.E you cannot flash G9880 with firmware from G988U or G988U1 or the other way around.

What exactly changed from the S9 to the S20 that made that impossible ?

Any luck? I just got one in Canada and it only has 3g ad 4g so I was hoping I could flash a csc file.

So I attempted to edit the band config using QPST and QXDM, but I'm very unfamiliar with both programs and how to actually read and write information to the modem using those programs. Definitely not for the average user. Back in the days when devices had ESN numbers, I used to flash software using QPST and QXDM but there is a lot that has changed with those programs, and I wouldn't even know how to do that stuff today. If anyone has any knowledge about those two programs that can help me unlock all the US 5G bands for AT&T and Verizon that would extremely helpful.
