Flashing Android 10 to my S9+ - Samsung Galaxy S9+ Questions & Answers

Alright so I've been trying to flash Android 10 on my S9+ because it wont update on it's own. The phone was originally Verizon but its unlocked and has the tmobile firmware now which is my current firmware. I downloaded the correct firmware for my phone and it's for tmobile but when I try to flash with Odin I get "FAIL! (DeviceInfo)" in the log.
I've tried both the normal CSC and the HOME CSC as well as a modded Odin ( https://forum.xda-developers.com/android/software/patched-odin-3-13-1-t3762572 ). Also I've been following the guide that was on sammobile's site, which is also where I got the firmware. Any idea on what I'm doing wrong?

got developer settings and adb unlocked?

Check your rev builds. It could be that the build you're trying to flash has a lower rev than what your phone has.

Samsung Galaxy S5 soft bricked and not able to use Unified toolkit

Hi all,
I am a newbie and don't know much. So please bear with me.
I was trying to root my Galaxy S5(SM-G900H) by using the tutorial given on http://forum.xda-developers.com/showthread.php?t=2696537 but the process did not go as planned as keep struck on recovery.img on odin3.10 so I googled and found that changing USB port will help so I take out the battery changed the port and try again but this time I soft-bricked the phone as odin struck on cache.img and now when i try to start my phone I get Firmware upgrade encountered. So now I again googled and found about unified toolkit and install it on my windows 10 ,now when i choose option 6 (i.e. flash stock boot image to your device) it says waiting for usb debugging to be enabled ,now I remember I turn USB debugging on but it is still struck here. Now what should I do? My parents gave this phone just a week ago and I am in deep trouble.
P.S.-I am only able go into the download mode not recovery mode.
Boot into Download Mode and use Odin to install the original firmware. Might require a factory reset after if still bootlooping. Here is a link to 6.0.1 from Sri Lanka https://mega.nz/#!YMAFhR4a!pZmf7OEWgzDzET1FLGsAOQ5XyVlvE8y4pJfB8KDNbMI . Any region firmware should work for the F model. If you want your specific one then check sammobile.com. I just linked to the other because it is a much faster download.
Problem encountred while installing original firmware
I tried to use Odin to install original firmware , I started the process but Odin got struck on sboot.bin (Also I read somewhere that whole process does not take more than 10 minutes). So please help me.
Which firmware did you try?
You might be able to use Kies to recover your device as well.

I downloaded it from http://www.teamandroiders.com/samsung-galaxy-s5-sm-g900h-stock-rom-firmware/ with PDA: I9500XXUBOL2. I want to know one more thing as I am in India so should I use INU or INS?

Oh geez...no wonder it isn't working. i9500 = S4. Really gotta be careful with that kind of thing.
INU is for unlocked from the factory
INS is for phones from a carrier
Either one should work. As mentioned, with the G900h, any firmware should work that is for that model, no matter the region. Use the one I posted and change the language or grab the one for India from sammobile.com though it'll take an hour or 2.
Edit: I see that it was just mislabeled as i9500, but the download says g900h after all.
Were you on 5.1.1 or 5.0 before you started this process?

Well I downloaded another one from http://firmwarefile.com/samsung-sm-g900h the second one, before it all started I was on 5.0 and the link you give does not work anymore. Anyway I tried with the firmware with upper link. And Odin is struck with sboot.bin for more than an hour. And have no idea what's going on? So what should I do?
Also someone suggested to use Pit. Should I use it?
No, don't use the pit. Try the newer firmware for 6.0

So I downloaded the 3rd link from http://firmwarefile.com/samsung-sm-g900h for newer version and try Odin 11.2 with it. I try two times to flash the firmware first time it struck on sboot.bin and second time it just showed fails(I used Odin with administrative rights this time) .Please see the attached images. Please tell me what should I do now. I want to repair it ASAP.
Not sure. This is pretty standard stuff. Have used Odin 1000 times and haven't had that much trouble with it. Sorry.

I think I should mention that the firmware I used was INS not INU and if you have a genuine link for version 6 for INU with fast download speed, please share it (different than sammobile because it has only fast speed only for premium users). Should I use PIT or try something else than Odin. Anything that might help please tell me. I have got this phone just a week ago and my parents are not gonna give me a new one so please help me.
I keep encountering sboot.bin error ,maybe there is a way to resolve it?

I want to know one more thing on the above link there is a custom firmware and there is a custom ROM with bootloader and all. So should I flash custom firmware or use the instructions given on thread to flash custom ROM?
The custom rom does not include bootloader and modem. You will need to flash via Odin if you were not on the same firmware as the software is based off of. I would flash them anyway, to be safe. You can skip the root part as it is not need. Follow the instruction in post 2 for stock rom users minus the root part. Make sure to boot directly back into TWRP recovery before it attempts to boot. You can load rom on SD card and any additional add-ons you want. Plenty of youtube guides on how to use Odin to flash TWRP and such.

Finally seen some progress, thank you very much. I successfully flashed TWRP recovery, but I got a couple of questions. Firstly I should flash ROM from recovery mode and then go to download mode to flash boot-loader and Modem files right? Should I flash ROM from SD card? And if this custom ROM causes problem is there a way to get to stock ROM? And is this custom ROM rooted or I have to root it via CF-Auto root or try anything else?
Rom might work without bootloader and modem. Just depends on your previous firmware. I would try and flash it though as it was recommended. Rom flash from SD card or internal. Either way should work. You will be able to go back to stock if you can find a firmware that works. It is already rooted.

Thank you very much.phone is working again with custom ROM.just one more thing if I upgrade from custom ROM what will happen?
:good::highfive::victory:
It should work to reflash the original firmware through Odin. Just get the one that matches your baseband version.

Downgrade necessary for carrier/csc change? August 1st update

Hey guys,
Bought the galaxy s8 plus from a store thinking it was factory unlocked version directly from samsung, but it wasnt. Its the unlocked sprint version based on the radio, and it had a tmobile app or two already installed. I am using AT&T and would like to change the carrier to at&t so that I can get a few features for at&t (Mainly being able to send mms while on wifi). I updated to the latest online update (which im guessing i shouldnt have) and i would like to know if its possible to easily change the carrier still, and or if i can downgrade safely to change the carrier. If so, what files are the latest that I can get the ball rolling with? Using the AT&T version is completely fine.
I came across this youtube video that shows how to easily change carrier without flashing: https://www.youtube.com/watch?v=msAHhCVF-F8
Basically i am a bit lost and would like to know if anyone can help at this point. Here are my software information:
Bootloader Version: G955USQU1AQGL
Build number NRD90M.G955USQU1AQGL
Active CSC Code: XAS
Please advise, thanks guys!

Goto updato.com to download the latest AT&T stock firmware. Extract and flash the files in Odin. If you flash all the files (AP, BL, CP And CSC) you will wipe everything on the phone so backup first. If you don't want to start over, then just flash CP and CSC.
There are two versions, 955U and 955U1. The U version is carrier specific and will contain their own software bloat. The U1 version is unbranded so no carrier bloat.
If you need more details, search for carrier switch.

Hey my friend,
Thanks so much for reaching back with an update and for the support! Awesome! So, youre 100% sure downgrade procedure wont brick the device? Also, do you know if this will this trip knox? Last question: do you think this will solve the red tint on the edges of the phone? I heard this was supposedly a software issue, not hardware.

Ok, so I tried it and with the unbranded XAA version and I am getting a "FAIL! Model dismatch fail" in odin. Even tried renaming files to tar and removing md5 at the end.
I also noticed that when in download mode, there are no green words going across the screen like I see in youtube videos who get it after they connect it. Could it be i do not have specific drivers installed? I installed the samsung usb drivers.
EDIT: Scratch that, the odin PrinceComsy version (Has to have the banner at the top) seems to be working fine. I am currently flashing

Download quick reboot for your phone and use the app to get into download mode. Make sure you have debug settings turned on in phone. Also check if you can access the phone when its plugged into your computer. If you see it as a drive, then the drivers were installed correctly. If not, uninstall and reinstall.

Awesome. ok, so i got it to work. But now when i reflash the rom back for sprint, the splash screen is stuck to AT&T and does not remove or go unbranded no matter what i do. It even has bloatware for att when the system starts. I never flashed att rom, only sprint unbranded XAS, not sure how this is happening. How can i get unlocked gsm and cdma back unbranded for sprint? I even formatted everything and flashed the user data, still the same. Its weird
Also, I am flashing it back to return the phone to store the way I received it. This red tint is just unacceptable.

Yes that firmware is unbranded. The CSC from XAA will automatically detect your carrier's sim and use that network.

Ok, so just tried it and the sprint CDMA is no longer available in the Mobile Networks menu., only the following:
Mobile Data
International Data Roamin
Disable 2G
Access Point Names
Network Operators (AT&T underneath)
There is no option to choose CDMA like there was before I just firmware changed. The XAS firmware that I had offered the option to choose automatic, LTE/3G, CDMA. Now its gone from the menu after the XAA flash.

Forgot you have to be rooted use the app. There's an adb command you can use instead. Just do a search in xda for preconfig carrier switch.

N970U and N970U1 Firmware Links Here

For those who aren't already aware, N970U is the model number of all of the US carrier versions of the Note 10. The N970U1 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.
This is not a "beginner's guide to Odin flashing" type post/thread, so I won't list basic, step-by-step instructions. My threads are geared towards those who already know what they're doing. If you're new to manually flashing Samsung firmware, I recommend you consult one of the "beginner's" posts/threads - there are tons of them here on XDA.
Happy flashing!
U firmware: https://www.androidfilehost.com/?w=files&flid=297977
U1 firmware: https://www.androidfilehost.com/?w=files&flid=297978
NOTES:
- DON'T QUOTE THE OP WHEN YOU REPLY, kthx
- I have an identical thread for the Note 10+
- My zips are compressed extra small for space and bandwidth savings. The default Windows extractor can't handle it, so you'll need a 3rd party tool like 7zip, WinRAR, etc
- My naming method for folders on AFH 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. Flashing USERDATA will also wipe data
- I know AFH servers/mirrors can be wonky sometimes, so if you want to download the latest version of whatever firmware you're seeking yourself, you can do so via SamFirm or Frija (plenty of links and threads here on XDA). I pay for a subscription to a site that gets beta builds and also gets the official releases (usually) before they hit SamFirm, so that's where my files come from. However, I don't have unlimited bandwidth on the site, and it's also quite time consuming to download the files, zip them up, and upload them to AFH. And, I do threads like this for every single Sx and Note x model - so I won't be uploading every single update version. The only full builds that I upload are ones where I get access to a new bootloader and/or Android version early, before they hit SamFirm.
- You can get USERDATAs from SamFirm for everything but AT&T and Cricket- those files will never be on SamFirm. So I'll try to always upload at least one USERDATA per bootloader increment for those carriers, and I'll also upload any full builds if AT&T is the only carrier to get that specific build, because you won't be able to find the files anywhere else.
- For USERDATAS (all the others are self explanatory):
AIO = Cricket
CCT = Xfinity Mobile (Comcast)
CHA - Spectrum Mobile (Charter)
TMK = Metro PCS
- the correct procedure for switching from one carrier's firmware to another is:
1. Flash full U1 firmware package including non HOME CSC
2. Upon boot, insert a SIM of the carrier whose firmware you want
3. Watch for the popup that says "reboot to apply new carrier settings" etc, and do it
4. After that restart completes, reboot back to Download mode and flash the full U firmware package, with the USERDATA file of the carrier whose firmware you want
Firmware is now available via SamFirm and Frija, but manual entry is required in a lot more cases than previous models. Hopefully that's just because the phone technically doesn't release until Friday, and that they change that on Friday or soon after.
Manual entry is currently required for VZW, CHA, and TMB U firmware, and for all carriers/regions/CSCs of U1 firmware

I only saw the news about the Verizon models getting updated. Theoretically that means that Xfinity and Charter should also have updates, since they all get the same updates at the same time. Not sure about any other models yet

By the way, I did use manual entry in SamFirm to find TMB firmware and download it. As a rule of thumb, I usually don't flash my phones right away after getting it, as I want to make sure that it isn't defective

Cool, my PC is ready and setup for Note10 Any idea if XAA firmware and the carrier's firmware are within the range/build date to allowing flashing? As I know the downgrade usually fails.

You can't downgrade if there's only one software version that's been released so far - there's nothing to downgrade to.
But even if it's months or years down the road, the flash will only fail if you're trying to downgrade bootloaders. As long as you operate within the same bootloader, you can flash anything you want
This is the one I'm getting direct from Samsung: SM-N970UZSAXAA. It is supposed to be unlocked. I asked for a Sprint sim Card. I hope it's not tied to Sprint, but can be moved to any US Carrier if I want to once the TMB-SPR merger completes.
SamFirm shows this firmware for TMB: N970USQU1ASH4 and I checked U1(XAA) as well and they are the same

Firmware is now available via SamFirm and Frija, but manual entry is required in a lot more cases than previous models. Hopefully that's just because the phone technically doesn't release until Friday, and that they change that on Friday or soon after.
Manual entry is currently required for VZW, CHA, and TMB U firmware, and for all carriers/regions/CSCs of U1 firmware

Looks like everything is back to normal, in SamFirm. Manual entry is now only required for VZW U firmware, as has traditionally been the case. Also, if you type in an older version for VZW, it will automatically give you the newest version, if there is one. So you don't have to always know the exact newest version - entering in the correct details of any previous version should always trigger the newest one.
Also, SH4 is now showing as the newest build for U1, T-Mobile, and Verizon. Spectrum gets SH5 (no idea why), and Sprint is still back on SGO.

Received my Note 10 U1, tested it on original firmware XAA(build: ASGO) and just now completed flashing to T-MO without updating to ASH4 build and want the phone to find and update firmware to see if OTA works. To get to download mode, I needed to press Vol + and - and power and the same time.
Flashed 5 files: BL, AP, CP, regular CSC and USERDATA. Device shows T-Mobile logo at boot, has Advanced Messaging, Video Call and I don't see any bloatware except for couple of T-Mo apps.
Went through setup and was able to get new OTA with August 1 patch(screenshot)
Wow great job! Can I get the link for the 10+ ...
I have the unlocked one but I have att and the only way to get wifi calling is flashing the U firmware

You can go to my profile to find all of my threads. But flashing U probably won't give you wifi calling. It's been extensively discussed in my S10 threads, and it usually doesn't work if you have a U1 model

Quick question, did your provider codes change? I flashed the Verizon files and am still stuck on XAA? Any help would be appreciated.

Initially, before I put in TMB sim, phone was on XAA/XAA/XAA. Now after all was said and done, my phone shows TMB/TMB/XAA. Make sure you put in the sim when you get the phone and when it has original firmware, so it can apply sim carrier's settings. Then you can flash and get the results that you need.

Thanks man I'll give that a shot.
@iBowToAndroid It states in the op that these models are all interchangeable. I have a U1 and flashed it to vzw U now when I try to Flash back to U1 it fails and says model mismatch???? Any help would be appreciated.

That's not much information.
1. What's the current U build?
2. Which U1 build are you trying to flash?
3. Where do you get that error exactly?
4. What Odin version are you using?
5. Do you get any other errors, either in Odin or on the phone itself?

Sorry, the phone was purchased as a unlocked version from samsung, model number SM-N970UZSAXAA/SM-970U1 is what the box says.
1. N970USQU1AHS4 is the build that I was able to flash. And the actual problem is that I had a brain fart and didn't read your simple instructions and instead of booting the phone first I opened the box and flashed the firmware. The issue I am having is my "Service provider SW ver. is stuck at XAA/XAA/XAA and I'm trying to get it to switch to VZW.
2. N970U1UEU1ASH4 I looked at all the n970u1 firmwares on samfirm and this was the only one that had XAA.
3. After I load the files into their locations and hit start it checks the files and the fails on the 4th step, I can run it again and find out exactly if you'd like.
4. 3.13.1 patched I believe.
5. None
I may be taking the wrong route to answer my problem. I really need help with getting it to show the right service provider code VZW.
Thank you for your help.

Flashing U1_XAA firmware to Note 8?

My Note 8 was purchased from ATT a couple of years ago. I received the Pie update. Then I decided to switch to T Mobile. As soon as I booted up with a T Mobile SIM, the firmware changed itself to T Mobile.
Now I want to gift this phone to someone who lives in China. I tried to flash the latest U1_XAA firmware to the phone, but so far, it has failed to flash. Is this even possible? Or is there something special I needed to do to flash it with Odin?
Thank you.

Follow the instructions to switch from N950U to N950U1 and you'll be fine just don't try to flash anything with a lower boot loader version it'll always fail! If you're on boot loader version 5 then you HAVE TO flash either 5 or 6 no going backwards to 4 or lower! There's a page on the forums to switch from N950U to N950U1.. It's easy to do. This is the page! Make sure you read from page 1 to understand! https://forum.xda-developers.com/galaxy-note-8/how-to/guide-sm-n950u-u1-t3685884

Thank you!
I am a noob at this. I've downloaded the latest U1_XAA firmware from Sammobile. Since I don't know how to decipher the firmware file name to see what bootloader it is, I assumed that it is equal or higher than the Android Pie in my Note 8. I will try flashing again with the PrinceComsy Odin again later since my phone has carrier's Android Pie right now (ATT to T Mobile automatically).
Just checked. Phone has PDA N950USQS6DSG6 and CSC N950UOYN6DSG6. I downloaded PDA N950U1UES6DSH1 and CSC N950U1OYM6DSH1 from Sammobile. Looks like they both are booloader 6, no? Will try PrinceComsy to flash.
Tried flashing, it failed. Don't know what to do now...

You need to make sure you use the right Odin and if it doesn't work just reboot into recovery mode and factory reset the phone so you can at least use it where it was before.
I've tried Patched, Prince, and regular Odin. They all failed...
Just wondering if the automatic change of ATT to T Mobile firmware when I changed carrier has anything messing this up.

Does it at least boot up? If it does you can just send it the way it is and let whoever you're giving it to see if their sim card will work. It appears as if it's on the latest firmware version already which is boot loader version 6 so you might not be able to switch to the U1 version because Samsung might have blocked it in the new version.
Yeah, it operates as normal when I leave the loading screen. The phone was already unlocked and was used in Asia and Asian SIM card as an ATT phone. If there is nothing else I could do, I'll just have to give it out like the way it is.
Thanks for your help.

SM-T978U Odin Firmware Flash

Purchased a sim unlocked SM-T978U (Verizon Tab S7+ 5G) and am trying to flash the unlocked or Tmobile stock firmware to it. I've gotten "passed" flashes everything when flashing all of the files from the corresponding stock firmwares, but everything it boots back into the Verizon firmware. Any suggestions as to what I'm doing wrong that would cause this? I've probably flashed this thing 20 times at this point.
its a verizon tablet so thats normal.. u need to change csc is all
Thought that was part of flashing it with the patched version of Odin with a different CSC version of the firmware, but I've not done this before. Any suggestions or resources you can point to on how to do this? Thanks!

patched odin only removes hash checks.. all the firmware has multi csc (all the usa csc) so simply flashing firmware doesnt change csc
Gotcha, so change the CSC first, then flash the matching firmware? What's the best method for changing the CSC on the S7+? This process? https://www.**********.com/how-to-change-csc-in-samsung-galaxy-phones/
Any suggestions on how to change the CSC? I've hit a wall and haven't been able to find a way to change it and then flash the desired firmware.

You need to flash with odin, wipe, then pop the other carrier sim in, on reboot it will boot with that carrier sw.

Ok, so SIM out, Odin flash with the TMB firmware. Then, what do you mean "wipe?" Is that just choosing the CSC file in Odin so that it resets all data, or some step after to wipe it?
So I tried again with these steps and had the same result, back into the Verizon firmware.
Removed Tmobile Sim
Odin flash TMB firmware
Tablet reboots automatically into VZW firmware
Then booted into recovery mode and performed a factory reset and cache wipe
Reinserted Sim and reboot
Tablet still boots into VZW firmware
I also tried this same process but with the unlocked "USC" firmware with the same results.
Am I supposed to somehow prevent the first boot after odin flash to perform the factory reset? I've tried that unsuccessfully but maybe I have the timing off or something.

dunno wat ur flashing but all the firmware is the same.. theyre all multi csc.. so simply flashing different firmwares wont change csc lol
I don't know if this will help but on some samsung phones you can change the csc by opening the dailer and typing "*#272*IMEI number#"
edit: IMEI must me copied from the about tablet section in the settings. Press on the IMEI for a second and it will be copied to clipboard. Typing the IMEI will not likely not work.
After entering this in the dailer a menu pops up and you can select csc. Note this will usually factory reset the device.
Yes if you try this, please let me know if it works. I have the T878u 5g from Tmobile.
Any update on this? I purchased an SM-T978U (on Samsung website that is t-mobile S7+)
I expected it to not be carrier or network locked but it was locked to the t-mobile network.
Would love to flash an unlocked firmware but I can't find SM-T978U firmware, let alone U1 firmware...... I realize that flashing U1 firmware won't unlock the network but T-mobile support tells me the device can't possibly be truly carrier locked because the IMEI isn't even in their system. So I thought maybe the carrier lock is in their app tied to the system instead of the actual device??
Anyway has anyone found the firmware for these devices? Sammobile doesn't seem to list SM-T978 as a device
These devices don't have a dialer so entering the IMEI method mentioned above won't work unless there is a trick?
Guys, for cross flashing, you must factory reset from within the OS before you flash. the newer security measures will not allow the device to accept even a full flash if the device is activation locked to an account. that is likely why you are flashing and still getting the vzw stuff to come up.
@elliwigy , though the devices are all loaded with multiple csc's, and you can change them on demand (if you know how), that will not automatically load the carrier branded bloatware that comes with each firmware, and certain settings that may, or may not, be enabled or disabled by the carrier. An example being native video calling that the verizon firmware has and the unlocked firmware does not.
I almost always flash my Verizon devices with the U1 XAA unlocked software. Among other things, this lets me get security patches faster, as i get them when sammy releases them, not when vzw gets around to it. I say almost always because there are still a few devices, like my tab s6, that are vzw models with some minor hardware changes that prevent it. But in the case of my Tab S7+ and my Note20Ultra, they are both rocking U1 XAA firmware.

Where is this U1 XAA firmware to download? Specifically for the SM-T978U?
RE: jmwfl2000 -I always untick the "Auto-Reboot" box when flashing new TWRP images to prevent stock recovery from being reapplied.After the first boot all should be well.

I'm pretty stumped like OP. Where are you finding U1 XAA for Tab S7+? Doesn't seem to turn up anywhere. Would definitely appreciate it if you could provide a link. Thanks.
I tried resetting before flashing and unchecked the auto-reboot but mine still returns to Tmobile. I just want the call and text on other devices feature.
Edit: I go the feature to work without flashing a new firmware but I am still looking for U1 XAA for the tab if anyone found it.

I bought an unlocked Verizon Tab S7, probably same seller. Its brand new, stil has plastic on it. Are you wanting to unlock Tmobile 5G bands?
