Samsung s9 stock rom question. - Samsung Galaxy S9 Questions & Answers

Hey guys, how are you doing.
I need your help, because i have a samsung s9 (SM-G960F) which is in a bootloop. I am trying to install a stock rom, but with all the ones that i have tried, odin has either got stuck on keystorage.img or, it has given me a secure check fail. As this occured inexpectedly, i don't know my csc code, so if any of you could find it, i will pay well.
Also, i have tried different odin version, all with the same result. And i tried all of the spanish softwares (because i am spanish)
my imei is 353467/10/733728/3
in download mode it says that FRP LOCK is on, Also OEM LOCK is too.
Thank you very much

where did you get your firmware from? try a fresh download of the firmware, the most current version of Odin, maybe try a different cable (this isnt a likely culprit) and finally a different computer. Those are basically the only things you can do in situations like these. if it was me, i would absolutely download a fresh firmware from sammobile and flash it as a first step. The sammobile link brings you to a page where you can select your country. You should be able to flash whatever countries firmware you want, but its best to flash the one that it was originally built with. You can look that up with the IMEI if you still have the box or the sticker on the back of the phone itself. Also, im thinking it could easily be the version of Odin youre using as they can be very finicky.
i littered an entire box of links in that reply for some odd reason. im bored
Edit:
also, i see this is your first post, so WELCOME to the forum!
Edit 2: i promise im gonna stop editing this post... eventually

Thx
thank you man, i will try that. quick question, is SAMFW.COM reliable? because i have been downloading the firmware from there

That doesn't fix issues for those of us that need to have the full stock firmware to re-Odin with. Guess those of us in the same boat wait a week or so. My problem was removing the knox files with root explorer. Bad move. Makes the phone unbootable. Called Samsung tech support and they confirmed that. Rooting no problem. Recovery screen totally blank. Never get to see the the white/green screen some say they have for a recovery screen. The magic use volume up keys 7 times etc I have seen posted don't work for me. Samsung specifically told me the stock firmware is proprietary, so they wouldn't give it to me. I can wait a week or so for developers to get their hands on appropriate files, including a custom recovery that actually works...like good old TWRP :victory:

have you tried to flash the S6 file? not the S6 edge but the S6. Try to get yourself in download mode and do that. Make sure you are using the correct odin. That is what happened to me and I was able to obtain ROOT.
If you can get into download mode, you can now use Kies to install the stock firmware. Just did it about 3 mins ago.

Where did you get the stock firmware. I'm not talking rooting file. I'm talking the full on tar to use to ODIN and flash the complete full stock firmware.

I used Kies to restore the Firmware. Unfortunately, I was unable to find the Firmware file on my computer (Or could not figure out how to use it). I did see a temp file that was the correct size, but it's name and extension were wrong. I tried to open the file using 7-Zip and WinRar, but neither would open it. At that point, I just allowed Kies to do it's job, and it worked well. Removed ROOT and am now running Stock Firmware and Stock Recovery. KNOX is still tripped, but I don't care at this point.
In Kies, use the option: "Firmware Upgrade and Initialization". You will need your Model Name and Serial Number. Found on the box or in Settings if you can get there. I've got a T-Mobile Edge, so my Model Name is SM-G925T. Your serial will be unique.

I deleted via root explorer a slew of knox fies. Samsung told me by doing this, it renders the phone non bootable. That is why I need a full stock firmware tar file I can use in Odin, to flash the original complete firmware for my 925 Edge.Removing root, re-rooting, will not help. Chainfire said that SamMobile rleased the firmware files but all I get is web page not available. Grrrrr. Really wish someone would post the file in the Development sections or at least provide a working link.

I had also removed all of the KNOX files, and most of the Samsung Files trying to get close to AOSP, but it became unstable. Kies re-installed the COMPLETE firmware again and all the stock files returned. I don't mean it removed ROOT only, it flashed the complete firmware. Kies uses ODIN internally to do the flash.

Well, someone (Pagel) already posted the 920 stock tar file in the S6 thread. so there MUST be a source currently. Wish I knew why Sammobile web site returns errors for me about unable to open web page. That's the source most state is where to go.

Okay I was able to find a workaround on how to restore my phone through Kies without getting an error.
do the following: 1) open Kies, click on tools, Firmware upgrade and initialisation, enter your model number and serial number and let it download the firmware, after an hour or so depending on your connection speed the firmware will be downloaded and your phone will reboot into recovery to install the firmware. done

That's exactly what I was saying to do a few posts back. Did it yesterday and it worked fine.
EDIT: I'm going to run through it again and see if I can find the downloaded file. I believe I found it last time, but it was not a TAR file, rather a temp file specific to MY phone. But I'll try again, and if I get it, will post it here.

No problem, as long as we all get there at some point. The temp file that Kies downloads is called tmpE635.tmp It ends up being about 1.6GB in size. I tried to open it using 7-Zip and WinRar, but neither will open it. I'll post it in case anyone wants to try using it in ODIN. I don't know if it is specific to MY phone, or the T-Mobile S6 Edge in general (SM-G295T).
But, honestly, I would suggest you use Kies yourself so you are positive to get the correct file. You WILL get the error message that says Kies does not support your phone, just ignore that and keep going.
Phone Serial Number
I just realized that the Serial Number Kies is asking for is not on my Box. It's in the settings/about/status menu, and also on a sticker that is stuck to the Plastic Wrap that was around the phone in the box. Looks sort of like this: R58G31D1PBA. So, if you cannot get into your settings, or don't have that plastic, I'm not positive how you will get it to start the download. Maybe if you just use someone elses serial number, that will start the download???
EDIT: Link to the Temp File from Kies (not sure you'll be able to do anything with it)

[ROOT][Samsung Galaxy Tab E][sm-t377p/sm-t560nu]

WHATS THIS?
This is my port of CF-AUTOROOT for the Samsung Galaxy TAB E.
You flash this at your own risk. Please ensure you have the stock ROM to hand downloaded from SAMMOBILE or a TWRP backup in case of problems. This will trip the knox counter.
Flash with ODIN 3.10.7 in the AP slot.
Load the respective file below into the AP slot and hit start.
cfautoroot_sm-t377p.tar
cfautoroot_sm-t560nu.tar
NOTE: ON SOME 5.1.1 DEVICES IT IS NECESSARY TO GO TO:
Settings -> Developer Options -> OEM unlocking
AND ENABLE OEM UNLOCK FIRST OR YOU MAY ENCOUNTER 'BLOCKED BY FRP LOCK' WHEN FLASHING.
STOCK TWRP IMAGE FOR SM-T377P
This is a link to the stock system, boot, modem image for the T377P in case anyone needs it. Needs to be restored with twrp.
Thanks to @shawn1976 for providing this.

FRP lock
Any suggestions on getting pass an FRP lock? My niece tried to root it but didn't turn on the enable OEM unlock. I just literally got it so don't have a back up and stock rom is no where I can find online even tried the Samsung Switch software and the T377P is not an option.

Isn't there a recovery mode in the SS software that allows the firmware to be reflashed?

That was my plan ...however they do not support this model number yet so its not available to be reflashed. I checked sammobile as well figuring I could download firmware and use Odin to reflash and same situation.
There's a chance the sm-t377R4 firmware may flash as it's practically identical to the sprint firmware just a different csc.
Okay....will try and find that one.
Hi, I had a question. The Samsung Tab E is my first android device (I am a IOS user, so i know how to Jailbreak, but I don't know how to root!). My friend told me to root it, but I don't really know how to do it. Can you post a step by step tutorial. Also, after i rooted can i update my device to a newer version or do i have to remove the root. Lastly, how do you back up your device? Thank you! I appreciate your hard work!

You can follow the tutorial below, it's for the Tab A but the procedure is identical.
Obviously don't use the cf_autoroot file in the tutorial use the one here. Also note the PDA button in Odin is now called AP.

You can update your device with odin anytime you want but not via ota.
To back up you device you need to install TWRP.
Search Google for info on using TWRP.

I tried the t377R4 firmware that didn't work. Any idea on where I could track down a copy of the t377p? Odd I can't even use the Samsung Smart Switch or even Kies as it doesn't recognize the model number. Or if anyone has a backup available they can share please let me know.
I have a US Cellular Samsung Tab E SM-T377R4 and I rooted it using the procedure below. The root process went fine and everything is working well except Recovery Mode does not work. It just boots to a black blank screen when I try to go to Recovery Mode. But that's no big deal to me.

Surprised recovery doesn't work, considering the 2 devices are identical specs.
Try installing Twrp, you'll probably find that works OK.

Rooting gone bad... Rooted my SM-T377P with KingRoot and there is an FRP Lock that comes up a week later. All of the custom ROM versions I have keep getting rejected by ODIN every time I try to flash them. The only other way I can think of doing this is to flash the stock ROM for the device.

Im wanting to de-Cricket my S9
Its a G960U, so i assume that all i would really need to do is flash the U1 firmware, correct?
and if that is correct, it will give me a Sammy splash screen and boot animation too, yes? Perhaps some sophomoric questions, but im just making sure.

Yep that's right, it will remove all the carrier crap (I assume splash, definitely boot), just remember about the bootloader/baseband versions that cannot be downgraded so if you flash to version 4 you can only flash v4 or above after that
You will also receive updates direct from Samsung instead of the carrier

damnit. thats just my luck too :/ thank you for affirming my understanding of how this works. I came to the S9 recently but i do recall the odin flash process for the t-mobile S2's that required the individual files to be placed in Odin before flashing, so this is all old hat as far as the process goes. Any idea on how long it might be before the U1 firmwares are going to be available for V5?

Only Samsung knows, but a lot of firmwares are now on v5 so if I had to guess I'd say the next update probably will bump it up to v5, they said the security updates included in the June update required it to be updated
When it receives the next update is anyone's guess though
And yes, all 4 parts of the firmware to be flashed together in the corresponding ODIN sections, HOME_CSC will not reset the phone, CSC will reset it, use one or the other in the CSC section

Samsung galaxy S20 Ultra Super Image needed?

Hi,

Please can anyone help it was a lot of money?

first off, what did you do to brick an expensive phone? Is it because you can't wait for the update to come along that you tried switching different Firmware without back reading some threads beforehand?? i'm not here to offend you or belittle you, in fact we have the same device and variant, HK- SM-G9880 to be precise.

You probably have to read this topic about samkey so just dig this thread and read about the samkey. How it can fix your phone depends on what youll choose otherwise i can still suggest using samsung switch from pc and do an emergency installation but as always find a topic about it first and do the most suitable thing for you.

Hi thanks for comment... I flashed odin but it didn't remove lock. Maybe because it is a modern phone? I have given it to a local phone repair shop so hopefully they will fix for me.

Hi Folks,
I posted this thread and just wanted to thank everyone who offered advice. I have managed to fix the phone now.

Samsung Galaxy s9 Demo Security Error

Hello! This is my first post on any forum ever, so please be gentle.
Recently I dumpster dove behind a U.S. Cellular that had just gone out of business and I found this neat Samsung Galaxy S9 Live Demo phone. It was originally flashed with an SM-G960XU Firmware, but I wanted to de-demo mode it, so I thought I would flash an SM-G960U firmware on it instead.
This failed miserably and I now have the following error: "Security Error: This phone has been flashed with unauthorized software...". A picture of the error, as well as the other information I have been able to glean from the locked phone is attached.
Unfortunately, I knew nothing about androids before attempting to flash the phone, so I have no other data about the phone other than what is in the pictures.
Any help would be greatly appreciated.
Thank you very much,
Oronto
Meh... you have a parts queen, less the mobo.
Demo unit should be missing the baseband chip hardware inside, so even if you could flash the stock firmware you would be limited to using it with wifi.
Apart from that, what happens if you try to flash again with odin? i would try flashing the precedent firmware G960XU

Hi effry,
Thank you for your response. I would love to reflash it with its original firmware but I can’t find it anywhere on the internet! I did not realize I was supposed to back up the firmware before flashing it which was quite the mistake. Do you happen to know where I might be able to find this firmware?
Thank you very much,
Oronto
Start from here and check the exact phone model with the IMEI, it is printed on the bottom of the back of the phone (use a strong light, it's a small and light text)
Check Samsung IMEI information in SamFw.com
You can check Samsung IMEI information like Model, Region. And you can choose the exact firmware
samfw.com
After that you can use the same site to search for the correct firmware , donwload it and flash it with Odin

Hi Blackhawk,
Thanks for the response. What do you mean by a parts queen? Do you mean I should sell it for parts on eBay?
Thanks,

A hangar queen is the actual terminology. An aircraft used for donor parts to keep others flying.
The display, frame, battery, C port pcb, cam module should be good. The mobo is useless for use as a phone except as noted with wifi.
So if you have another phone of the same model... you now have an Android queen

Hi effry,
Thank you again! I input the model’s serial number into the website you linked and it returned that the firmware is SM-G960XZKUXAR. Unfortunately, that website doesn’t have the firmware that it tells me the phone is supposed to have. I checked elsewhere on the internet but I can’t seem to find it. Is there an obscure website you know of that might have it?
Alternatively, do you think it is possible that I could flash it with another equivalent firmware? If so, what might you suggest?
Thank you very much,

Hi blackhawk,
Thank you for your insight into which parts seem useful for scrapping. It is looking like I might have to do that. Unfortunately, I do not have an equivalent model, so I will have to sell it for parts if it comes down to that.
Thanks again,
Oronto

By looking online it seems that flashing the firmware with odin should fix the issue. Maybe you did something wrong in the process? i would try another odin flash using this firmware

Hello again effry,
I tried your firmwares and bad things have happened. It got to where the download was almost finished and then it displayed this error. Unfortunately Smart Switch Emergency Software Recovery does not register it as connected.
I believe I am boned. Thoughts on this?
Thanks,
Oronto

You could just replace the motherboard from Ebay for around 50 bucks (USD). Make sure it's a regular unlocked version (both FRP and network), any carrier will do since you can cross flash any firmware of your choice (no need for the demo anymore). Just a heads up, demo units sometimes are missing some of the LTE antenna cables/connectors, which would prevent the good replacement main board from working on cellular.

Hi billa,
Thanks for the advice. I’ll look into it, but I might end up just selling it for parts.
Thanks,
