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

Hi, I have been trying to get my s4 i9505 networked unlock. It's currently on EE. I bought it from someone who has gone abroad so can't ask them to get ee to do it. I have tried 3 online unlocking sites, the last was recommended on here but non of them can do it. I have tried to install several firmwares but hoping that would remove the ee lock But they all seem to be ee firmware. Is there a firmware that you can tell me about which will do what I want. Or is there a way I can conect to my computer and do a hardware unlock. Hope someone can help as getting desperate now.
A friend of mine has a insurance supplied s4 i9505 Which is unlocked. Is there a way we can copy the firmware on his and install on my or completely clone the phone . ?
Installing firmware will not remove a carrier unlock. Downgrading firmware from Android 4.4.2 to Android 4.2 may work if attempting to use the free unlocking methods on the forums. Naturally, using those methods have risks, up to and including totally bricking the phone. The carrier lock mechanism is part of the modem firmware as RegionLock Away modifies the modem when it functions. Hardware unlocking probably can be done, but I couldn't tell you how it's done. I also can't tell you if copying your friend's modem will help your cause. I CAN tell you that completely cloning his phone is completely illegal and you could render both his and your phones completely useless by trying it.

Thank you for the reply, can I install a modem . I think I have read that you can't down grade the firmware ? If this is wrong. Where can I find the 4.2 firmware . Thanks
You can try, but I don't believe it will help any. While I said that the carrier lock is part of the modem firmware, it's not as simple as installing new modem firmware. The modem firmware that people commonly install really only controls the radios, while the carrier lock is in a different part. That part doesn't usually get touched by a new firmware install. In my experience, the carrier lock reared its ugly head when I destabilized the NV memory of my S4, which caused a reset to the golden backup in the phone.
I also had a SIM tray issue which popped up at the same time, and only by rolling back the firmware to 4.2.2 was I able to get to a stage to unlock the phone, using RegionLock Away. It is possible to roll back the firmware itself, but you cannot roll back the bootloader. Using old firmware with a new bootloader results in a "Kernel is not SEAndroid Enforcing" complaint upon boot.
To cut this down to basics, you can install a 4.2.2 modem and attempt one of the unlock methods available, as long as you are fully aware of the risks involved. If you choose this route you can download a modem from the appropriate thread on XDA and install it through Odin. You'll need to do a search to find it, but it shouldn't be too difficult. Full ROMs are available from www.sammobile.com or www.samsung-updates.com.

Is there anyone on here in uk who can offer to unlock this phone for me
Hi all. I have been having huge amounts of trouble getting the marshmallow bootloader, and modem on my phone. I have tried to Flash and Odin. I have tried to flash with flash fire. I have tried with TW RP. I always get failure messages. Error messages. Or the phone just boot loops and will not start up. My phone is an SM - s902l, which is Straight Talk's version of the g900v. My bootloader is not locked, I have been flashing ROMs on this thing for years now. Am I not going to be able to get the g900v modem and boot loader on this phone? Are they really two different animals? I would love to be able to flash all of the newly available marshmallow ROMs, but they usually require marshmallow bootloader and modem.Need some help, as I have run into wall after wall on this... Thanks in advance
Also, I cannot download firmware from Sam mobile.com I'm given either an upgrade super member status ship type thing, or nothing else.
Hello, All!
I have a G930V (Verizon S7) Non-EDGE, and I wan't to convert it to a G930U Unbranded (Or at least bloat free).
## BY THE WAY ##
Yes, I have seen other threads on this topic. Doesn't answer my confusions though.
Threads by:
tvm2487 (G930U Firmware)
James.Markham0757 (Can someone send me in the right direction...)
DeathAngel66669 (Using SamFirm to download SM-G930U-G930UUEU2APG9...)
## BY THE WAY ##
So anyways here are my questions.
##
1. Looking through Sammobile or Updato I see that a the newest version is
(G930UUEU2APEH) on (XAA), Would that work for the VZW Variant if not, What can i use?
2. Regarding my phone's below details would i be able to convert it to any of the 'U' Firmwares?
3. I don't wan't to trip any security features or mess with KNOX, really don't want to root.
Really just wan't to keep my warranty. Granted I will probably lose that by not using VZW firmware.
4. I thought flashing firmwares not similar to your phone will brick it permenantly. Why does the 'U' firmware run on the 'V'?
5. If i can flash the firmware (Odin?), What should i tick in the boxes for it to flash perfectly fine without errors?
Given this would be my first Samsung Tweaking.
6. Besides the Verizon bloat, What other cons are in the 'U' firmware that I should know about before doing the procedure?
7. Chances of bricking the phone? Would it be reversible?
##
My current S7 VZW Details:
Model: SM-G930V
Ver: 6.0.1
Patch Level: October, 1, 2016
Baseband Ver: G930VVRU4API3
I appreciate the help and your time. Thanks !
1. Looking through Sammobile or Updato I see that a the newest version is
(G930UUEU2APEH) on (XAA), Would that work for the VZW Variant if not, What can i use?
I don’t think it would flash as it is bootloader 2(5th character from right) latest firmware is 4!
2. Regarding my phone's below details would i be able to convert it to any of the 'U' Firmwares?
From what I understand all the USA variants of the Galaxy S7's are the same hardware
3. I don't wan't to trip any security features or mess with KNOX, really don't want to root.
Really just wan't to keep my warranty. Granted I will probably lose that by not using VZW firmware.
I have an AT&T branded S7 SM-G930A and have flashed the U firmware and used it for a while. I have now switched carriers to T-Mobile used the U firmware without issues and now flashed the T-Mobile firmware and it works fine. KNOW IS NOT TRIPPED.
4. I thought flashing firmwares not similar to your phone will brick it permenantly. Why does the 'U' firmware run on the 'V'?
Not sure, Odin may just fail to complete install?
5. If i can flash the firmware (Odin?), What should i tick in the boxes for it to flash perfectly fine without errors?
Given this would be my first Samsung Tweaking.
I never had luck flashing the HOME-CSC file, had to use straight CSC.
6. Besides the Verizon bloat, What other cons are in the 'U' firmware that I should know about before doing the procedure?
One thing I did notice is the visual voicemail app tends to work better when using the specific carrier firmware(both AT&T & T-Mobile).
I'm using T-Mobile and I don't see a need to go back to U at this time as their is not much bloat on the T-Mobile firmware.
7. Chances of bricking the phone? Would it be reversible?

I just installed T-Mobile Nougat on my phone and got the error on phone and it was stuck on “You will need to use Smart Switch Recovery” to fix phone! SCARY!!! I managed to finally get firmware installed and running!
Understood.
When I get home today I'll try to install a newer version from SamMobile.
Updato has older versions. Sammobile has the latest which is.
G930U with code (VZW) on
G930UOYM4APL2
(https://www.sammobile.com/firmwares/download/118975/G930UUEU4APL2_G930UOYM4APL2_VZW/)
Would this be compatible?
G930UUEU4APL2 is the latest U-firmware. Everything flashes correctly, it won't trip KNOX, and it is super easy to go back to G930V firmware if you decide you want to send it back for warranty. You can't brick the phone by flashing signed files with Odin. The bootloader won't allow Odin to flash anything that could brick it.
I had already started replying before you posted above me. I'd recommend using my link to the firmware, as Sammobile downloads take FOREVER.
I see, I'm glad.
So, What would i need to make sure to do and not do in Odin 3.11.1?
AP/BL/CP/CSC from your zip? Just flash everything or only certain things?
Re-partition tick box? yes or no?
Flash all four of those files and DON'T CHANGE ANY Odin settings.
Okay. I just flashed it and now my phone repeatedly keeps booting into recovery.
The recovery logs and the red text at the bottom says:
dm-verity verification failed
Need to check DRK first...
Any ideas?
##PREVIOUS##
I think it might have to be because I used HOME_CSC rather than CSC.
What's the difference between both? Can i revert later?
##PREVIOUS##
@CVertigo1
I reflashed with the CSC file rather than the HOME_CSC file as according to your instructions in your thread (Latest G930U Firmware) and it worked perfectly fine!
KNOX is still at 0x0 and warranty void is fine.
( https://forum.xda-developers.com/verizon-galaxy-s7/how-to/g930u-firmware-pl2-g930v-success-t3558214 )
No bloat, amazingly fast, and some features i like are present. I'll report back to your thread on the battery life when i get more time with it.
I appreciate your patience.
(Will post screenshots later).
Home_CSC doesn't wipe user data, which causes issues when swapping firmware. That's what caused your bootloop.
Followed this, today, was sick and tired of the damn Verizon bloat slowing the phone down.
The phone runs faster - notably faster.
After installing the SIM, the phone returns, "Your device will restart to configure features supported by the new SIM card."
And then" It's useless. If I hard-power reset it, and take out the SIM, it's viable - it's just useless otherwise.
Phone is a G930V, flashed to G930U.
Any Suggestions? The phone is *NOT* rooted, so I can't easily take out or rename the AutoPreconfig.apk package.. Argh.
Will I get the android nougat update on this ROM?
Just converted G930V to G930U, all 100% working here in the UK. Fully debranded and no verizon warning about sim change. perfect
Mind telling me what thread you used to find the latest firmware? This forum for the phone is so rarely used anymore, it's hard to tell what info to go even go on anymore.
Is PL2 the latest for 930U? I'm VZW but US, not UK
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 BootloaderUnlocking 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?
I have a J500FN here, with a lot of bloat from the network operator (EE), so to make it a bit more desirable for selling, I'd like to flash the unbranded BTU firmware on it, which will at least only have Samsung bloat on it.
I have previously flashed another J500FN using Odin, the flash completed successfully, only for the phone to switch off and never boot again. When I Googled the issue, it seemed like a reasonably common problem with this phone.
Is there a specific way I need to flash it (other than following normal Odin procedures) or a specific version of Odin I need to use or something, to ensure this doesn't happen again with this one?
