Hi all,
New user here, not much experience rooting or messing with firmware for phones. I was following the guide on how to flash the SM-935U firmware to the verizon model of the Galaxy S7 Edge, and may have bricked my phone. Here's what I did.
Followed the guide to the letter.
Powered off phone, booted to Download mode
Fired up Odin, selected the SM-935U firmware files, and clicked start.
It gave me an Auth error, which research revealed means that I forgot to turn off Reactivation Lock. I figured, "Fine, I'll just disable it. However, I can't get the phone to boot again. Every time I leave download mode, it boots into Android Recovery, where, no matter what I do, it just reboots into Android Recovery. I can't Wipe anything because it can't mount /system - probably due to Reactivation Lock?
I've been research and researching ways around this, and everything I find just points back to flashing it with the stock firmware. But then I read that you can't even do that if Reactivation lock is on, because Odin will still fail with the Auth error. So, I can only get it to boot to recovery mode, and I can't flash it with anything?
I did read somewhere that if I choose to wipe the phone's EFS with Odin that it should override activation lock, but then it clears the phones IMEI, which is an even bigger mess, isn't it?
I feel like I have to be missing something... since it never did the wipe, why is it that I can't get past the recovery mode. Shouldn't I still be able to get into the system somehow?
Does Anyone have any thoughts or suggestions for me? I'd really like to not be stuck with a permanently bricked S7 edge if at all possible....
Solved
Just wanted to post this to help anyone else who might have this issue. Turns out that you can flash the stock firmware, as long as you're flashing at least the same version or newer of the stock firmware as what the phone was running prior to getting stuck in recovery mode. It shows you what version it was running in the recovery mode at the top.
So for me, I googled the exact firmware version that recovery mode said the phone was running, downloaded it, flashed it with ODIN, and it worked just fine. Had to choose to wipe with the recovery mode after I flashed it, but then it booted like normal. - Then I enabled OEM unlocking under the developer menu, and tried flashing the U firmware again with ODIN, and it still failed with the auth error. Huh.
Turns out (maybe I wasn't doing it right or something) that you can't flash older versions of the firmware to the phone. But, as long as OEM unlocking is enabled, you can flash the U (unlocked) version of the current firmware to the phone and it will take just fine. Hint: I was able to determine the "version" number by looking at the last 4-5 characters of the build number... the verizon version I was running for my SM-935V was: VZW-G935VVRU4API3 - So I googled the API3 firmware and found the U (unlocked) version for my carrier (I happen to be using T-Mobile) on this site: https://samsung-firmware.org/model/SM-G935U/ and found the zip file name which was TMB-G935UUEU4API3-20161011161050.zip, googled that, got the rapidgator link, downloaded it, and that flashed just fine to the phone, and now my T-Mobile SIM works perfectly in what was previously the SM-935V, which now identifies as an SM-935U in settings. It's beautiful.
Also, you need the PIT file, but I was able to use the PIT file for the phone model number (again, found at the top of the android recovery menu), which for my phone was: HERO2QLTE_USA_VZW.pit (googled that and got it off androidfilehost) - I was able to use that PIT file for the T-Mobile U version of the firmware and it worked just fine.
Hope this helps someone.
Hi Guys
This is my first post on xda even after using these forums for years. But today I cant find a solution on here or anywhere for that fact, and was literally hoping that I've missed something somewhere.
So to start. I have a Samsung Galaxy J5 Prime (SM-G570F). The other day I was flashing a custom rom when something went wrong during the flashing process and left me with a bricked device. Now I did do a full backup before flashing as I've learned the hard way how important this is. During the flashing it also asked me for a full wipe and to backup the EFS. Even though I did do all the backups and wiped everything< I've ticked both boxes and proceeded with the installation. Everything seemed fine but on 99.9% it froze. Not wanting to do anything I left it until it rebooted the phone by itself, where I was greeted with the download/flash screen. Didn't even give the warning about installing custom software and asked to continue. It just booted straight to the download screen. Tried getting back into recovery only to be greeted with download screen. No matter what I did it just kept booting into download mode. So I then re-flashed TWRP. Getting into the recovery I was able to mount EFS, System, Data, etc. Bu all showed 0mb of 0mb available. I then went to restore everything only to find that the SD Card was also wiped by the process. Thinking that maybe the recovery isn't reading everything correctly, I found the SD Card empty in windows also. No call me names or whatever, (I know my own stupidity) but I never backed up my backups on my PC. So I just proceeded flashing stock firmware as to start from scratch. Everything went as planned until the device got reset by odin. I was greeted with a screen saying "installing system update", but as soon as it reach 32% it changes to "erasing" and then "error" with the "DRK Missing" error. Then it boots to recovery where an error message is saying "unable to mount: EFS (Device or Recourse busy). I cleared cache and did a factory reset and it booted the system (Though mount error still appears in recovery even in custom TWRP/CWM recoveries also). Now I have a 00000..... IMEI number and no network connection. I've spent the last week on the web trying to find a solution with no luck. I'm tired AF because I didn't sleep trying to solve this. I tried flashing stock and custom roms, recovery's, boot-loaders, modems. Tried different software's like Samsung Tool, IMEI repair tool, Strings of adb commands, xposed modules, apps, terminals, etc. I even flashed factory binaries with no luck as to how to change it back.
So in short.
My EFS got wiped.
I lost my IMEI.
I don't have any backups.
Been awake for a week searching for solutions with no luck.
So please if anyone knows of a way to change the IMEI, please help me. I know It's illegal to change IMEI (though not in my country). But I down't want to change it for all the wrong reasons. I just want to change it back to the original found on the back of the phone and on the box. This can't do any harm can it? Please I just want my phone back please!

Android version - Nougat 7.0
Baseband version - G570FXXU1BQI6

If this problem is still open, then on Your Phone box is writen imei, or take battery out and under serial number there will be your imei, root your device and use IMEI changer grant root access and type your imei in it, after that reboot and your imei should pop up! I had same issue and this steps made my day! THIS WORKS ONLY ON YOUR IMEI, YOU CAN'T CRACK, STEAL IMEI By this method, don't believe those Dumb ****'s from YouTube!
May I help You!

Can you tell us more?
How did it start?
Did something happen to it, or did you just notice it is not connecting?
The most easy things first, is your sim card correctly in place?
Which ROM are you on and have you reflashed it?

The phone started with problems since I upgraded to Android Pie, I have taken care of it very well but I do not know if it is a hardware failure, but note that in baseband turns out to be unknown, I installed several stock roms from fastboot without any success, also I thought it would be a problem of the EFS partition, but everything is fine I even took a backup in case the doubts, what could happen?

Did you originally update via OTA, meaning, was it the official update?
Then when you noticed it's not working, you tried to flash several stock ROMs?
One possible problem that comes to mind, is that for some reason, you have the wrong radio/modem firmware. That can happen for example, if you have flashed a ROM, which is not meant for your region.

Yes, upgrade to Android pie via OTA
I already put a stock rom of the same region, following each fastboot command one by one, but everything continues the same, I even installed RROS 7, to see if at least it turned on the wifi, and it is in bootloop.

Go with the modding guide index: how to restore stock ROM etc., and flash a stock ROM that you know will work. Flash the radio/modem file too, and make sure it's the correct one.
Just to say, I had connection problems too, and in the end they were because the sim card did not latch correctly in place i.e. was not correctly in place.

I already tried, I installed the rom corresponding to the model of the cell phone and the wifi still does not work, the base band is still unknown, I also checked if the sim card was correctly placed, and everything is fine

Great that you have an idea. ?
Here's an idea: take a backup of your current config in twrp, move it to the computer, take a copy. Replace the files in that copy with the ones that you want to flash.
Did you mean this? You are aware that you can try different radio/modem files through fastboot, not having to flash everything else every time? That said, go with your idea. ?

Ok, but WiFi should work even if there is no mobile data available.
I probably can't help at this point, apologies! My suggestion is to flash a stock ROM, lock the bootloader and send the phone for repairs. There could be a solution to this, but I'm out of ideas. ?*

from what I see, if there is no baseband it does not detect the sim card and it does not turn on the wifi, I will try to force an OTA retail update

Hello, colud you solve the problem? Because I am havig a very similar one...
Hello group friends, I'm new here. I have a similar problem, I was using the Havoc 2.4 rom, when upgrading to 2.6 I no longer recognize my SIM card and the wi-fi does not connect, I can not install another rom anymore, nor rom stock, recovery TRWP has been replaced by the Havoc and the Wipe System function does not work, and for a few days you can not stay in recovery mode anymore, it restarts every 3 seconds, not the time to click the options. Can someone help me. I'm without a cell phone, and I need it.
I have a similar issue after flashing the latest firmware. SIM goes to "SIM locked" every ten seconds or so, and Wifi drops at the same tie. It's like networking is being reset every 10 seconds. No network settings I've tried change that.
I've flashed several stock ROMs; the one I had previously, newest, oldest, both for RETEU and retail. I used Lenovo restore to upgrade but that resulted in soft brick, after that I flashed the latest firmware via Fastboot and that's when the problem started.
With Oreo, wifi and cellular don't work at all, nothing detected. With Pie they're connected and dropped in a loop. I can't help thinking that the Lenovo restore broke this somehow, but modem files have been reflashed several times after that with no change. I'm not getting the baseband error.

I have the exact same problem, I wasn't able to repair it so I sent it to service and tomorrow they will try to fix it for $35. The problem with goign back to previous versions is that you loose the IMEI and MAC . The problem with the pie version I believe is the baseband. If the service is able to fix it I will post the solution here for you to fix it .

Sorry I answer so late, I didn's see the message before.
I believe you already tried puting it into bootloader mode. If that's the case, I had a similar problem recently an it solved alone, I let it loop for a while and suddenly fell, into dtock recovey, i factory reset (with stock recovery) and somehow stock was booted ( i believe it was because it was in inactive slot).
Hope this helps you

I am still working on this, I actually did this to a work phone (I had permission to root/unroot). Something that has helped me so far is just getting familiar with the whole flashing process - https://android.gadgethacks.com/how...actory-images-android-using-fastboot-0175277/. I think from this article the problem lies in the modem/radio rom. That *should* be the only thing you need to flash on. However, I have noticed with a lot of roms on here, a modem rom is not included on the stock firmware. But that needs to match well to your phone from what I understand. I have tried a few modem roms already, unfortunately, but no luck.
