Unflashable S7Edge?

I have an S7 Edge from Verizon that I had previously flashed U on. I was going to try flashing the AT&T FW so I could flash the unreleased final Nougat.
I found the AT&T stock FW (G935AUCS4APK1) but Odin would not flash it. It stalls at
<ID:0/006> File analysis..
<ID:0/006> SetupConnection..
<ID:0/006> Initialzation..
and the phone displays "Odin protocol version error!". So I canceled the flash and rebooted, and got a screen that said "An error has occurred while updating the device software. Use the emergency recovery function in the Smart Switch PC software".
Now, I can't flash anything. Every FW I try to flash with Odin results in the "Odin protocol version error!". Smart Switch does not recognize the phone either.
A little help please?

Maybe try a diff USB port/cable? Did you have more than one of each file like ap others?

I had two CSC files. Hone_csc and CSC.
I had several different FW that I tried, the AT&T one I mentioned, PI3 Vzw and pl4 U. None will flash. I noticed that download mode shows the model number as g935a now. I tracked down a newer version of Odin that's supposed to work with the att model, but I haven't had a a chance to try it yet.
Edit: The 3.12 version of Odin worked and I got the AT&T APK1 to flash. Time to go flash Nougat!

I don't have a SIM card in it, though. Just using it to play around with the OS. SO far, it reminds me of my Note 7. I put the phone away in a drawer, just too depressing to use. I wish I never got rid of my Note 7.

Problem with my G935A

Hi, I got a S7 Edge SM-G935A from AT&T at the end of December.
That same night I tried to root my phone(i got a bootloop), and I didn't know the bootloader was locked.
So I re-flashed a SM-G935U rom, but I would like to go back to the basic one in order to get a new start(SM-G935A), without root and nothing.
Knowing that I have a problem connecting to the wifi, maybe because of the rom that doesn't match.
And also i dont have samsung updates, i'd like to have the latest one im currently on 7.0.
If someone could help me to get my phone with original firmware, I'd be grateful.

Ok, first off, you can run any US/Qualcomm variant software on your device. Unless you just have a hankering for AT&T firmware, the U firmware will work just fine. Either way, find a full copy of either A or U firmware and ODIN it down, and you will essentially factory reset your device in the process.
There are links to both in this forum. I personally prefer U because it is faster and less bogged down with carrier crap, but if you are an AT&T customer, there are decent enough reasons to stick with A.
NOTE: you may need to use Prince Comsy's ODIN tool if you get a mismatch error. Unfortunately, there is no universal ODIN tool, but as a general rule, if you are CHANGING variants you need Prince's. If you are writing over the same version, you need the official.

Then this is easy. Go download the U firmware and use Prince's ODIN to convert it to a G935U. If you aren't on an AT&T network there is zero reason to keep your device on A firmware, starting with the fact that you will never get updates. (AT&T firmware will only update if you have an AT&T SIM installed.)

Only add-on is to perform this from a Windows 7 pc and not 10. Prince kept crashing on 10 and worked fine on 7.

S7 Edge Emergency help!!!

Hi, I have a huge problem, I locked myself out of my S7 edge and it frp'd on me after trying for days to fix the problem (I entered the wrong email and kept receiving the incorrect password message and I rest the password to wrong email and later deleted the email) I had my friend who is really good with fixing things. He got it to work and not sure how he did what he did, but he got an update tried to install it. It crashed and is telling me to use the Smart switch PC Emergency Recovery Function. But that's not the worst part.
The major problem is that it is showing that the phone is a SM-G935P. I don't know what he did or how he did it. But I am sure someone on this site can help. I have tried most of the Odin program's I seen and I have downloaded some much firmware that I am begging for help. Samsung said they will help with the frp once I get the phone back working some what can any one help. We been trying for about two months straight. I am going to upload a picture of what the screen days in download mode.

From what I can tell it seems your friend installed Sprint's newer firmware on your device which has a binary version of 6 while the other carriers' firmware are on binary version 4. Sprint did this to make it harder for their customers to switch mobile carriers by not allowing the device to downgrade the binary version (the binary/bootloader version of the firmware is indicated by the digit in the 5th from last character in the firmware version. G935PSPT6BRD2 as shown here the binary version is 6. So now you are stuck on Sprint's firmware and will need to download the latest version of their firmware link: https://www.sammobile.com/firmwares/galaxy-s7-edge/SM-G935p/
Use the PrinceCosmy version of Odin to flash this and you should be able to get back running from there.
Also by your Download Mode screen's information it also indicated that your FRP Lock is not activated so once you flash the updated Sprint firmware you should be golden.

Double check your firmware version you are flashing and that it is the latest Sprint firmware listed in Sammobile (G935PSPT6BRD2)

IMPORTANT REMINDER TO OTHER USERS SINCE THIS IS POSTED IN THE VERIZON FORUM: This is only a solution if you are experiencing the same issue with your phone model SM-G935P (Sprint)..Do not attempt to flash this particular firmware if you are not already stuck with the updated binary version Sprint pushed to their customers as of November 2017 because you will not be able to flash any other of the carriers' roms as it seems the others are not going to update their binary version. When this firmware is flashed to your phone you will (at least for the foreseeable future) be stuck with Sprint's version of the S7 Edge which includes their bloat etc...although you will still be able to unlock the phone for use on other carriers, it will prove to be very difficult to use your carrier's full extent of features as most of those features will not be available in this rom/firmware. Again if your device shows as any other model (G935A, G935V, G935T) then do the research to find the firmware for your model because you will have many more options staying away from this firmware, I've been reading many many posts where users have carelessly flashed Sprint's updated firmware and are unable to go back because of this.

Links for AT&T USERDATAs

I know these are much tougher to find - can't be obtained from SamFirm or SamMobile. So I'll be uploading one for each bootloader version. Firmware is universal on U models so you can use the other 4 files from any other matching collection. Can probably even mix and match builds, if you can't find files for the exact same build. Can't mix and match bootloaders though, so the other 4 files have to at least be from the same bootloader.
USERDATAs for any other CSCs can be gotten from SamFirm - for the latest version. If you need an old USERDATA for a CSC that's not commonly found on SamMobile (ACG, LRA, TFN, etc), let me know and I can probably get it.

Can I use the userdata file for G55USQU5CRF5 with the other four files being from the build G55USQS5CRF5? I'm not sure what the difference between SQU and SQS is, and if it is significant. Thank you!

Yes, you can. There basically is no difference

I'm begging someone to help me. I flashed my AT&T S8+ to the G955U1 unlocked firmware, then got accepted into the beta and installed it via OTA update. I now want to go back to a AT&T rom so I can have stuff like Wi-fi calling and VOLTE back. I've tried so many different roms with ATT userdata and they all fail with ODIN. I'm guessing its something to do with bootloader version. Is there any way I can get back to a AT&T ROM from the G955U1 Pie beta firmware.

I finally managed to get Odin to flash a ROM. All of them I tried were bootloader 5. But now the problem is I cant get OTA updates. My phone is back to being a AT&T one with the AT&T boot screen and wi-fi calling etc etc. But everytime I check for updates it says its up to date even though I have CRL1 and the latest AT&T firmware is U5CSA4. I would update form SD card but that wipes the phone every time. I had to do that 4 or 5 times just to get to CRL1 because it kept saying my phone is up to date.

1. AT&T phones don't OTA if you're using a carrier other than AT&T - even their own MVNOs
2. If you are using AT&T, OTA rollouts are staged. It just came out less than a week ago, so your phone might not have been green-lit yet
3. Both 1 and 2 are really irrelevant anyways, because you can just Odin flash any update you want. Using HOME CSC will ensure data isn't wiped

I am using AT&T. I know rollouts are staged but I've never had it tell me my phone is up to date when it is 7 versions behind which it was because I had to start at CRF5 since that is the newest AT&T Userdata file I could find. I checked after doing the update from SD card method each time, making sure to put the date on my phone forward since AT&T only lets you manually check once a day. No matter what it said I was up to date despite being several versions behind.
I'm gonna try using Odin to flash one more time because not being able to do OTA update is a HUGE PIA. Dose it matter that the user data is called "ATT_G955USQU5CRF5" despite the firmware being USQS because I couldn't find a USQUCRF5 and besides AT&T's update history shows USQSCRF5 anyways. What I did was downloaded a verizon G955USQS5CRF5 ODIN file (because for some reason AT&T odin files are really hard to find) and replaced the Verizon user data with the AT&T one.
Also if I flash say CSA4 verizon with the verizon user data the put my AT&T sim card in it dose it not download all the the carrier bloatware and what not? dose that basically turn it back into a AT&T phone? or could I take that CSA4 and flash it with the CRF5 AT&T user data?

1. I have no idea what the difference is between SQS and SQU. Even on the same network, it seems to be completely random as to which one gets assigned to each new update. I don't think it matters
2. Don't flash userdata if you're going to Odin flash a different carrier's version. Just do the normal 4 files

Sorry for the late reply. But just wanted to say that this method of getting from a G955U1 (US Unlocked) firmware back to AT&T branded firmware did end up working. I did eventually start getting OTA updates after using the method I mentioned (flashing Verizon USQS5CRF5 ROM files with AT&T G955USQS5CRF5 USERDATA file using ODIN Odin3 v3.13.1 3B Patched). Then updating to the then latest version using the update.zip method using files from the "Firmware Science" site (I think that's the name). Then about two days after AT&T released a new update I actually got it OTA. However after it installed successfully my chrome app became broken. Opening it and hitting the ... button in the top right would open the menu but all the options just said "chrome". Tried clearing the cache and files of Chrome but then it just crashed when launched. Had to do a reset (not a big deal since I had a Samsung SmartSwitch backup on my SD Card). Just hope that dose not happen every OTA, but guessing it was a weird fluke.

Hey I am in the same boat. Can you please help pointing to the files you used to ODIN to get back to ATT version.

SC1 USERDATA was added a few days ago, for anyone wanting to jump to Pie

USERDATA added for bootloader 6

USERDATA added for bootloader 7

Ive been researching and reading most of the day about returning to stock on an att 955u. The only download i can find that wont take 6 hours is from samfirm and is G955USQS7DSL2. Can i use this and the userdata from your link to return this back to stock?

Since the USERDATA is TA5, I would recommend using a build that's closer to that one. You can get TA3 from SamFirm under regions/CSCs ACG, CCT, LRA, SPR, TFN, or VZW.
When you say "returning to stock", what firmware is currently on the device?

I was on a verizon build. I ended up returning to stock with G955USQS6DSG4, got one update and now says no firmware. Currently shows G955USQU6DSH8.

Do you have all of AT&T's apps and bloatware now? If so, it should be updating at least to SJ3, if not up to TA5. You would need an active AT&T SIM inserted in order to pull the update though

Yea just uninstalled and disabled a bunch of att and samsung bloat. I am currently running an att sim. Should i possible download the v7 files and try again? Shouldn't matter that the firmware was from "tmobile" right its the userdata that counts iirc.

Flashed a different carrier's firmware...now I can't flash anymore

I have a TracFone S8+. I recently flashed it with the Verizon combination and stock firmware. Now, whenever I'm trying to flash it to anything, I either
get stuck at SetupConnection for a while before getting "All threads completed success 0 / failed 1", or
get the Complete(Write) error
I tried the method where I click the start button before immediately entering download mode. That did nothing. I also tried flashing it again with both Verizon and Tracfone files. Neither succeeded. I used different versions of Odin, as well as the Prince and the new patched editions. My phone is working fine, but I'm worried that problems may arise by not having the original carrier's firmware, esp. when I still have TracFone as my carrier.

Nothing bad should happen service wise. A lot of tracphone uses Verizon towers. As long as you download the TracFone apps.
Ok first off.
The combination is a multi carrier firmware. It is test firmware from Samsung not the carrier. So when you flashed that and then switched to Verizon that set Verizon as the CSC.
What you are looking for is a TracFone CSC from your current firmware version 5th digit back from far end is a 1 through 5. That determines the revision. This could cause a Odin failure. If it's lower than current.
So now that's some what explained.
If you can find that revision of firmware's CSC file you can flash that in Odin with your tracfones sim installed and it should revert back to TracFone if you think it's nessicary. If your on the newer 8.0 firmwares you need that modded Odin 3.12b I think. Those firmware are in a different file type. Not .tar files. So that will cause a fail too.
I'm always around if all those check out we can go from there:good:
There is also a dialer code to select csc but I think hidden menus are disabled on Verizon.
Lss all the firmwares are identical for all the us models. They all have identical hardware.
Pretty much what determines anything is the csc file

Thank you for your help! It's invaluable.
Okay, so I found Verizon's firmware to be G955UOYN2CRB9. However, Tracfone's is G955USQU5CRL2. If the number before the C is indeed the bootloader version, then that means I'm trying to upgrade from 2 to 5. Is that possible?

Yes. You just can't go back to the revision 2 firmware after. You can upgrade just not downgrade

Okay, now I'm seriously boggled. When I go to Software Update section in settings, it tells me that the current version is indeed G955USQU5CRL2/G955UOYN5CRL2/G955USQU5CRL2. Even though the last successful flash was Verizon. Do you know what could've happened here!? And why I still get an error when I flash the phone with TracFone firmware?

I have a Verizon phone with Verizon firmware and the 5th digit from the right is a 5. It appears you have Verizon firmware flashed on your phone

Interesting. When I visited SamMobile's page for G955U, I found that PDA associated with TracFone as well.
