I have a Samsung A7 2017 (SM-A720F) brought from UAE having latest Oreo update. While I tried to flash an INS version over this Odin detects the phone. But after hitting start it takes some time and gives error like failed. I also tried to root it with CF-AutoRoot file. Those also have the same error. Developer mode, USB debugging and OEM unlock are ON. Trying with windows 10 + Odin 3.13 (latest). Any solution ?
Combination file successfully flashed. But, still not able to flash another country File. Can I proceed with original country file (i.e XSG stock firmware) ?
Please help me

Root with twrp and magisk, cfautoroot is OG in my opinion . Try flashing just CSC_home or whatever it is called in Odin.

I'm able to flash Combination file, original country (XSG) file and also flashes TWRP. But, I can't get access to TWRP after flashing it. Always it replaced by Stock recovery. And apart these 3 files nothing flashes, including CSC file alone...

When you flash twrp, untick auto reboot in odin. Boot straight into twrp without booting system.

It won't help change the csc. But hadesrom oneui has a huge selection of csc's you can select when flashing it.

If I flashed HadesROM OneUI with 'INS' CSC can I able to downgrade it with INS Stock firmware in future ?
Is the binary thing really need to consider while flashing that ?
PS : I looked on HadesROM. It is temptating. But, the real problem is with VoLTE which affects the network badly here... The VoLTE only network is a large mess here... And thanks for your unconditional Help & Support :fingers-crossed:

It should work to change csc with Hades and then flash stock. Just make sure you don't reflash csc then because it could change.

By Odin flash TWRP, copy the Magisk file to the memory of the phone or to the SD card and Magisk flash by TPWR recovery.
When you restart, install the Magisk manager apk and that's it.

This is normal and it happened because you flashed the AP file only
If you want to get rid of these Russian providers menus and have stock settings menu you need to flash the full rom files (BL+AP+CP+CSC) via Odin.

No you shouldn't get a fail.

Many people reported that the Russian firmware is working flawlessly on A320FL Model and no one mentioned any issues during the flash process.
For me, first time i flashed the rom the flash progress stopped near the end because i was using the 3.10.7 (not 3.12.7 as you mentioned) version just like you.
After using the 3.12.3 version it worked perfectly.
So you nead to use the latest version of Odin (3.12.3)
Whether this method can be applied in galaxy a7 2017 running in nougat?

if you want a clean install first install Nougat BL AP CP CSC of your device. After first boot on the settings screen, shutdown the device and go into bootloader mode, select AP from OREO, no other one, only AP. Press start and you A320FL will be upgrade to OREO. I installed Russia Oreo on A320Y

CSC Oreo will get error of pit file wrong. BL Oreo will get error of Bootloader wrong. CP Oreo will get error of modem wrong. AP Oreo only contain upgrade files, this file is the correct to upgrade. Now, if you want a clean install, first flash Nougat and then flash only AP file from Russia Oreo, other ones files (BL, CP, CSC) are get error because not corresponding to device

Flashing an official stock ROM (with Odin) should never trip Knox. At least it never happened to me with other Samsung phones (Galaxy Ace, Galaxy S3 Mini, Galaxy Alpha). I haven't tried with this one, but I bet it will be safe.
OK I have officially screwed up...
So it was all going smoothly flashing a tweaked custom rom and twrp successfully and then I decided to back to stock...
I accidentally (ok maybe not so accidentally) flipped the OEM unlock switch and now I am locked out of my phone since I still had the custom binary on the phone.
I tried to flash the latest stock firmware for the s9 BTU found from samfirm but odin seemed to have not liked the firmware or something and it gave me an a red message on the odin mode screen.
When I try to flash everything at once I get "REV Failed Check (Bootloader)"
When I try to flash just AP I get "REV Failed Check (Kernel)"
At the moment when I boot up I get the message telling me to use emergency software recovery but Smart Switch does not seem to recognise the device either in the emergency recovery page however it does try to connect on the home page.
I'm not too sure what to do, any help would be nice?
Thank you
You cannot downgrade the bootloader, check which version your phone has in Download mode (BL: xx) and check which version the firmware you are flashing has G960FXXU1BRF8

OK I think I have found the BL version from the line that says...
"RP SWREV B:2 K:2 S:2"
But what firmware has the BL Version 2? They all seem to have a BL version of 1 from what you've said?
If there are no firmware which match this, what do I do? Is my phone redundant?

Yea you'll either have to do something like that, or wait for your region firmware to have it's BL updated
Tried it out with a BL2 BTU firmware from SamMobile and the flash went smoothly however now I'm stuck in a bootloop when I'm trying to boot up.
I know this could be anything but I can't get any form of logs as the only mode I have is Odin mode available to me...
The way I flashed it was by doing BL first followed by AP, CP then CSC separately with auto reboot and one other one checked that was instructed by SamMobile. I tried to do them together but I keep getting an error of not being able to read a line.
What should my next step be?
What could be the reason for this bootloop as according to Odin the flash went well?
Thanks in advance

You might need to check "Repartition" in ODIN only, flash all 4 parts at the same time, use CSC and not HOME_CSC
Make sure you are using ODIN 3.13.1
Oh yea forgot the update...
I got it working, I think I unchecked repartition and auto reboot whilst flashing all of them together to get it working
So yea this is now solved
So i have a samsung s9 SM-G960F/DS version. i had have run TWRP on it and magisk + exposed and it worked fine. i had to uninstall exposed to log into some apps and then i would reinstall it agian. but when i ran the exposed unintaller the phone would not boot. i tryed diffrent things and it would not boot unless it had the exposed intalled on it. i did a complete wipe of the phone with TWRP and now i can´t install stock rom. i downloaded the latest stock ROM for my model and the latest odin that can handle the lz4 compression. bur when i but in BL AP CP CSC it just get stuck on system.img all the time. i there is simply nothing i have not tryed. and nothing works for me. The only think working is if i flash the TWRP then i can boot into recovery TWRP. thats it. i am at a point where i will pay anyone who can help me figure this out cause i almost lost all hope for this to work agian. So i really really hope someone here have an ide to what could work for me. every tip and trick i will test and if someone offer help via discord or somthing i would also be glad to hear from you.
Hi
Extract and flash bootload.img or hidden.img file from the main stock rom.
I'll check the actual file name for you when I get home later. Did experience that problem sometime back on my s6 edge.
Usually there is a small error message on the screen of the s9 if odin fails or stalls. It's small blue text, I have a feeling it's either 'magic string error' or 'SYSTEM not [Sec]' or close to it. I find this happens when flashing the wrong firmware for that model. Example, flashing G960N firmware for a G960F.
I just did a reflash and here are my exact steps for my G960F.
1. Download Odin 3.13.1
2. Make sure Samsung Drivers are installed
3. Grab the latest firmware for your device, my device is a G960F so I just picked the latest BRJ3 firmware with November patch from Updato. Just get the firmware for your exact model.
4. Extract the files from the ZIP file
5. Add all the correct BL, AP, CP and CSC files to odin.
6. Select nand erase
7. Boot S9 into download mode
8. Flash to phone.
Don't try to flash TWRP before installing the full firmwares and until the phone is setup.
If all fails, and because you seem to be able to install TWRP, then you can download TGP Kernel ROM and flash that. It is based on stock G960F firmware, has a nice aroma installer for selecting various things and tweaks. It also provides a clean install of Magisk if that's something you like.
Also be sure to flash no-DM Verify.
Make sure you're not trying to downgrade the bootloader, I'm sick of writing out the same guide each time and I just did it earlier today so shouldn't be hard to find

You should look for samfirm or frija tool . Those would help you get latest firmware for your phone. Download it , flash it with odin and everything should be fine. Just remember that its possible that as you would be on latest firmware, you might not be able to downgrade in future.
Many users report imei errors months after rooting. I don't recommend rooting. we do not know the origin of the problem
Hi friends.
On Topjohnwu's github, there´s a note about root any Samsung without recovery
Basically, extract the AP from stock firmware, copy it to phone, install magisk from xda forum, patch it, download the patched file to your pc and flash it using Odin.
You must fresh flash the entire ROM and the patched AP, userdata MUST be formatted (use CSC, not HOME_CSC)
Use it at your own risk, Knox wil be tripped and you could brick your phone.
Search the note into Topjohnwu´s github, Magisk section, Install and search for specific samsung section.
Be careful and enjoy rooting!

Here's my story, I patched the AP file and flashed it using odin, didn't add any other stock firmware files. I was able to attain root privileges, then the unthinkable happened. I received a call and it got disconnected instantly. The network signals vanished, I restarted the phone and was welcomed with a flash notification message "IMEI null or invalid."
I've since flashed it 10-12 times.
IMEI hasn't been restored, wifi works though.
I've given up hope now, my daughter attends her school classes on it.
I have never heard of such a case. Where did you get the boot.img from? It must be the same version as your phone. I recommend you flash a clean software by Odin, without root, and verify that everything is normal

Were you able to root it?
Also, in addition to the patched AP file do we need to flash the BL, CP and CSC files?
Yep no issues. Magisk hide, all working.
When you extracted the boot img, there where another files into the AP file provided by samsung that must be flashed too.
Do you have the patched file? Try flashing BL, CP, CSC and AP and then flash again only the patched boot.img into AP.
But I think it has nothing to the root with loose of imei.
Was your phone a company one? Like verizon, etc?

No, it's unlocked. Did you patch the whole AP file or just the boot file through magisk? I patched the entire AP file. If you could please list all the steps, it would be a huge help. Thanks.
