G900V firmware on my G900A phone

Hei all,
I bought my phone off ebay without realizing that there are different models for different markets. However inside the battery case the model number is SM-G900A. Since I off course wanted the latest android version that my wife has on her G900F I went about googling for a solution. After lots of tries and lots of failures, I eventually managed to root my phone with towelroot. I went on to flash a G900V firmware onto my phone (Don't ask why). Now I have a G900V baseband, bootloader and rom entirely. I then went on to update OTA to end up with Android 6.0.1 version only to realize that it cannot be rooted yet. I then went back to 5.0 in order to root and to install custom Twrp 3.0.2.2 recovery and unlock the bootloader to developer mode using sambootloader unlocker.
My question is this: How the h... was I able to transform my G900A to a G900V model to begin with. This is over a year ago, and I cannot remember how I went about it. What I do remember is that I used ODIN, with a G900V pit file and did a complete wipe checking repartition, nand erase all, phone efs clear, and bootloader update.
Now my follow up question is this: If it was possible to "transform" my G900A into G900V, would it be possible to "transform" it into a G900F model given that the hardware on the phone is identical ? I mean what is it that makes the phone a G900V, G900F, G900A model in the first place ?
Would it be possible to completely repartition the internal memory of the phone and flash a complete G900F package with bootloader, recovery, system, modems etc ?
If you are inclined to answer this with a short no, then please be so kind to explain why my phone now only accepts G900V firmware ?

You have done something very risky
Flashing another phone's PIT is a quick way to hardbrick (*i've done it before. what an argue at the service center!*)
Don't try to convert to a G900F... that's an even more different phone
Simply flash G900A PIT+FIRMWARE
Also, NEVER TOUCH any checkboxes in Odin like nand erase all and phone efs clear! Your phone will never work on cell signal again.
There is no way it should not accept ATT firmware because the signing key is in true ROM on Qualcomm S5s I believe

this is risky and dangerous i know all partitions except bootloaders can be flashed with flashfire on a bootloader unlocked phone but ive never heard of someone flashing bootloaders succesfully i wouldnt attempt it and agree with lightning i do remember g900a and g900v modems seem to be compatible but im dangerously curious can you remeber anything else oja60

No, not really. All I can remember is best described in the post above. I bought an S5 from ebay, probably delivered from asia somewhere. The back of the phone said G900A and I was curious as to why I couldn't get any OTA-updates. I the downloaded a G900V pit file and a stock G900V ROM from sammobile, and went at it. After installing it all the phone worked like a charm, so I could then go about rooting and unlocking the bootloader with the above mentioned method.
I have now gotten a hold of a G900F phone which I wanted to begin with. That means I could try the procedure again to see If it's possible to convert the now G900V phone into a G900F in the same way. I need to specify this however: We are not talking about running a G900F ROM on an unlocked G900V bootloader here (That's easy!). This is about converting the whole shambam. What I still haven't gotten an answer to is what makes a G900V a G900V and what makes the other models unique ?
Best regards
OJA

Custom binary blocked by frp lock

need urgent help really.
my phone has been rooted and has twrp installed for months now with no issues, all of a sudden my phone rebooted to the samsung logo screen with the mentioned error message. i have no idea how and why this error has occured but my phone wont boot to system. i really dont want flash stock firmware as i havent backed things up, is there a way to fix this issue with out doing a full wipe?

you might have accidentally disable oem unlock. so phone is bricked , and you need to flash stock firmware with odin , no other choices . and as you know knox counter will stay 0x1 , root or no root, once you break knox its permanent as knox is hardware, once you root it break an electronic fuse so once you flash stock firmware I really suggest you to install custom rom and twrp again as many things will be blocked if you stay on stock firmware as your device will stay marked as " rooted "

Yeah I had to do firmware install in the end. It's just crazy though. I very rarely go into dev options, I had noto kernel installed and everything on stock aqh3, rooted with magisk and everything worked great, so annoying as this happened at 3am and I have slow internet connection and took me 2 hours to download the 3.5gb firmware file. Urgh o was on the verge of installing a custom rom too, ah well good job I had a lot of stuff saved in Samsung cloud.

yes hopefully cloud is our new god ^^ yes its annoying I agree but its also a great feeling to begin with a clean phone like new after a reset , and I have also a crappy download speed so yes its a pain to download 4gb , and even better when its corrupted and need to download agin good luck with your device

Hey guys I need help.
My phone got bricked as you said (I accidentally turned off OEM unlock on my rooted phone) so I tried to flash stock firmware, but odin fails and on my phone it says (sw rev. check fail. device:3 binary:2). Plz help!
My phone: S8+
FIRMWARE: CRF7
FRP LOCK: ON
OEM LOCK: ON

Just had the very same problem meself ?
Thank god for Odin and https://updato.com/
Bt like previous posters says its like havin a new phone apart from samsung pay not working

Can someone help??
I got the "FRP lock" on my Samsung S8 (Exynos) and tried to flash Stock Oreo but Odin fails and the device shows "KERNEL REV. CHECK FAIL. DEVICE:3 BINARY:2".
This stock Samsung Rom worked earlier today so it should be the right Rom for my phone.
Also tried to flash TWRP recovery via AP in Odin which failed with "RFP lock" message showing on the device..
I tried to add a snapshot here but couldn't.
Anyone please, I'm helpless..

Your issue is trying to flash older firmware than what is on your phone. You will need to download firmware with bootloader ver. 3 or higher ( bl ver no. is 5th number from right of firmware name )
Flashing twrp failed because of locked bootloader.

If you've rooted and flashed a custom rom your Knox was most likely tripped so you can't use Samsung apps anymore. You can mod shealth and get that working but that's about it. If you flash back to nougat you have to reset your phone.
If you flash nougat via Odin you'll have to reformat your phone
If you flash Oreo you won't need to since your system is already set to Oreo.
Also you said you did something that corrupted your storage, what exactly did you do?

Why not just flash a rooted Oreo rom that already has magisk? As for Samsung apps yeah you tripped Knox so those won't work anymore permanently

Sm-t280 frp locked binary

So long story short I was intoxicated and for some reason disabled OEM in debugging then sometime later I restarted my tablet to get the frp binary locked. It has a custom rom with twrp I absolutely need the data off of this tablet and the only way I see is to reinstall the default os through Odin but that wipes the device I need a method to get the data off of the tablet or a method to bypass frp entirely it would be mighty appreciated if I could have some help

Why don't you try a backup in TWRP?

Reinstalling the stock firmware with Odin won't wipe the device.

It's difficult to say if you can keep your data. The binary FRP lock is quite different that the average FRP lock that's associated with the Google sign in. Usually whenever you trip the binary lock it's because some firmware was installed such as a Root or a ROM that was flawed or invalid. It's an overstacking of binaries and therefore you get a "Custom Binaries Blocked by FRP Lock" notification. I've had this problem on another varient of the Tab A, the Galaxy Tab A6 SM-T580. I have found about four diferent variations of this. You may not have turned off OEM because in Binary lock it will act like you have. Possible reason to think that is the way it acts in Download Mode where you can't seem to flash anything especially the official firmware. Sound familiar?
Version 1. If you try to go to Recovery you get redirected to a screen similar to the Download Mode. In the upper left are red lettered "Custom Binaries Blocked by FRP Lock.. Download Mode is accessable but won't initialize when trying to flash stock firmware. Binary 4 FRP Unlock file was accepted and flashed in by Odin3. Stock firmware installs afterwards.
Version 2. Device is stuck in bootloop. "Custom Binaries Blocked by FRP Lock" appears on Logo screen. Recovery and Download Modes are so far, useless. Binary 4 FRP Unlock used, no positive results. Binary U 4 used. Positive result. Stock firmware flashed in afterwards.
Version 3. "Custom Binaries Blocked by FRP Lock" appears on Download Mode which either stalls right after or fails to initialize. Binary 4 FRP Unlock and Binary U 4 yeild no positive results. (This ones on it's way to me).
Version 4. "Custom Binaries Blocked by FRP Lock appears on Recovery Mode. Download Mode useless. I'm currently following this one.
Solution: I don't know if the one I have will work, they may be device specific. Research for a "SM-T280 Binary 4 FRP Unlock" which I couldn't yet find.

Nothing needs to be done except install the stock firmware.
The device hasn't been reset so no need for any kind of bypass.
FRP has kicked in purely because unsigned software is installed.
Replace the unsigned software with stock and it'll boot just fine. Data fully intact.

I hate to argue with you but that wasn't so easy with mine. While in Binary FRP lock I, along with a few others that have the SM-T580 or the SM-T585 couldn't use Download Mode to flash in the official stock firmware. Trial and error followed. The solve was first I had to flash in the Binary FRP Unlock and then I could flash in the firmware. With another device the owner tried the Binary Frp Unlock which didn't fix it. Later he flashed in the U4 Binary and that worked for him. I passed the info along to some others in the same predicament and it helped them. So I don't know what to tell you but what you're stating is not always applicable.

Trust me, I have 3 of these devices. I've bricked them, frp locked them every possible way during development for this device.
The T580 is a different device and may be more difficult to bypass if and only if FRP has kicked in because of a device reset.
However for EVERY Samsung device that has simply had non stock software installed the only fix that's required is to install the stock firmware.
This is the case on all the Samsung devices I own and I have quite a few from lollipop to Pie.

Wow, you're on a roll ain't ya? Hey ASHYX, dont misjudge me because of my stats you see here. Over a decade ago I was stacking ROMs into my HTC-G1. 3 decades ago I was an Electrical Engineer and Sonar Operator in the Navy. Let me tell you point blank, you're mistaken! Normally you would think you can just flash in stock OTA firmware into the device via Odin3 and you get to return to normal. Well that wasn't the solve for this. This was a new one to me also. If you think you're so right on what you say I'll be more than happy to point you in the direction of some XDA visitors, two of which are still Binary FRP locked. You can try telling them what you just told me and they'll probably call you a blooming idiot. No offense but you could try reading it properly which might help.
I said, [QOUTE] " While in Binary FRP lock I, along with a few others that have the SM-T580 or the SM-T585 couldn't use Download Mode to flash in the official stock firmware. [END QOUTE]
Take my word for it, the method you stated was already tried AND DID NOT WORK!
If you want to insist you're all that, here ya go, these people need your expertise in development

Data loss when flashing stock firmware.

That depends on which stock firmware you're using. Typically what you get OTA (over the air) is the same as the 4File Official Stock Firmware. These are the 4 files that go into each section when using Odin3 to flash firmware. BL is for the Bootloader which controls security, start-up and recovery. AP is Android Partitioning, CP is Cellular Processor. Now let's talk about the CSC. file. The 4File contains two CSC files, one is listed as HOME CSC. If you flash the CSC file you will lose your App data. If you flash the HOME CSC you do not lose your App data.

Depends on which custom rom you had installed? If it's stock based on lollipop then you should be fine. If its lineage then it may not boot without a data wipe.

Unbrand an LTE Tab A Sprint unlocked sm-t517P

Hello, I am trying to unbrand my LTE Tab A from Sprint SM-T517P by flashing another CSC, or flashing another PIT on a patched version of ODIN with no success.
Can anyone tell me how to do it properly? I have read about Chimera, and Samkey, but they are too expensive, and I worry about bricking my LTE tablet (do not want to root, and there is no root anyway).
Any help?

I made little progress. I think I got the latest correct firmware for it downloaded, but it didn't want to flash with a patched Odin, but it did flash successfully with a non patched version of Odin.
After that, I tried flashing a CSC from another firmware of an LTE that is unbranded (SM-T515), but I always get a SECURE CHECK FAIL PIT error.
Does that mean I need to unlock the bootloader? Is that even possible? I wonder how Chimera, or Samkey is able to change CSC thru just software, but they are too expensive for me
Any help?

I soft bricked the tablet by flashing the AP, CP, and CSC of the latest firmware of International unlocked model SM-T515... I was able to recover by flashing its latest firmware for SM-T517P.
I worry about hard bricking it, but after so many tries with different things, I feel so close
Flashing only the CSC of any other firmware hasn't worked so far, and flashing anything other than Android 10 Q doesn't work either, even after unlocking bootloader.
I have NOT flashed bootloader of another firmware yet, super worried I may hard brick it if I flash another BL even after unlocking its bootloader.

hmmm i dont think there are many modifying the sm-t517p. i also own one of those on t mobile . i wanted to add twrp and root ....i cant seem to find any version made for it...so onto the magisk played with thatfor a couple days and locked it up a few times ...i think for now ill be okay with no modding ..idk why im compelled to screw p a perfectly fine working tab-phone. i did however just see that kali linux can be run on it without messing the os up..maybe ill ry that next... why did you want to modify yours? so you could switch carriers im guessing? luckily for me t-mobile took over sprint........just curious

bootloader unlock...
Unlocking Bootloader​Unlocking the bootloader on modern Samsung devices have some caveats. The newly introduced VaultKeeper service will make the bootloader reject any unofficial partitions in some circumstances.
Allow bootloader unlocking in Developer options → OEM unlocking
Reboot to download mode: power off your device and press the download mode key combo for your device
Long press volume up to unlock the bootloader. This will wipe your data and automatically reboot.
Go through the initial setup. Skip through all the steps since data will be wiped again in later steps. Connect the device to Internet during the setup.
Enable developer options, and confirm that the OEM unlocking option exists and is grayed out. This means the VaultKeeper service has unleashed the bootloader.
Your bootloader now accepts unofficial images in download mode

Hi, I also have a sm-t517p and have searching to find twrp and root. So you had no luck at all? No root even with magisk?
