G955u engboot - AT&T Samsung Galaxy S8+ Guides, News, & Discussion

After downloading a bunch of files from all over, I found that this ENGBOOT flashed and booted with this Odin on my AT&T S8+. not sure if it will help anyone, but who knows...
Cant remember exactly where I found them, but I take no credit for their existence.

How do I unroot and reflash stock ROM onto AT&T G930A S7?

I am trying to unroot my phone. I have a US version of G930A. Sammobile has every county except the USA. I found G930AATT1APB5_User_Binary.zip which has AP_G930AUCU1APB5_CL7193387_QB8719495_REV02_user_low_ship_MULTI_CERT.tar, the BL, CP and CSC file in it. I try to flash it using Odin3, and I get an "odin protocol version error." I take it because the image is a lower version that's what's on there. I would like to download the latest stock image but sammobile doesn't offer images for the US? Or is there a better way?
Wrong forum. This here is for SM-G930F Development, not Q&A. You'll get the answers you're seeking and more, at the S7 AT&T Q&A and Dev forums. Mod, please move - thanks.
Wrong forum. But try using Kies in Download mode
That is what i do when ever i restore my phone.
No Kies good lord. This isn't a Note 2.
You're getting that error because you're on newer firmware than you're trying to flash so it's erroring out.
Follow the Return to stock procedure in this thread:
http://forum.xda-developers.com/ver...sed-unroot-t3411039/post67605246#post67605246
Flash all 4 files, then you'll be on PF2 and able to get the OTA Update to PG1 with wifi calling, etc.
I tried using kies. It asks me for my model. I put in SM-G930A. The serial I put in all caps and it tells me my model number I entered is wrong.

Which Odin are you using?
You're flashing the PF2?
I've tried many versions of Odin v1 (not the 3). I'm not sure what the PF2 is.
To get it to work, I just defaulted the phone and rerooted it. It's the only way I can get it to work. It's working perfect right now. Only question is how long,

for g930a (galaxy s7 at&t NOT EDGE)
WARNING: YOU WILL LOSE ALL DATA MAKE A BACKUP
download these files:
Odin: http://www.mediafire.com/download/2t...din_3.12.3.rar
Flashing Files: https://drive.google.com/file/d/0B17...w?usp=drivesdk
After downloading extract the .rar extract it then extract each, BL, AP, ect... files. Use the odin included in the download to flash and you will be returned to stock. If the odin included still gives you the error you can get the princecomsey version and see if that works from here: http://downloadandroidrom.com/file/tools/ODIN/ODIN-modified.zip
If odin freezes or crashes just restart it and try again, it might take a while foor the AP file to load into odin so just be patient and if it looks like it is about to crash wait about 2-3 minutes then force close it and try again.
Now you are returned to stock an all set !!
(p.s) - PF2 is the latest firmware as of now for the g930a, meaning when you flash this you will be all set. You may have tried to flash the original PF which is now outdated cause AT&T updated it, I did this and it worked but i could not update my phone so I flashed this one and it works perfectly and Samsung pay is up and running.

Can't restore G930P Firmware

Ok so here's my issue
For a very long time since the G930U firmware was available to install, I've been using that. Well I decided to want to get my phone unlocked for GSM using those services but it needs Stock Firmware.
So I tried to restore to the latest G930P firmware and ODIN is giving a Volume size error for the system.img.ex4. I've tried now a couple different firmwares and no luck. Any idea?
The latest Firmware is PH7 I don't recommend it. PG1 on down are good to go. Extract zip stock firmware to a folder and add it in to Odin all the slots accordingly. BL AP CP CSC the last slot CSC is HOME_CSC not CSC_SPT and start flashing. It always works for me.
I ended up figuring it out. I had to find the stock G930P .PIT mapping's and re-partition because G930U ended up changing the sizes.
Oh good to know. Thank for sharing
Why do you not recommend PH7 update? I've heard it helps with battery life.
Could you share the pit file you used. I tried the same thing with a pit file i found online how ever since the pit i am able to flash bootloader but unable to flash system.ext4. Odin gives me a "failed (auth)" and neyjer the 930u version or the f2 or any of the other stock roms wont flash.... Help please
Don't you just love it when people "figure it out" and then don't share how? lol
Here... Since nobody gave you this. This may not be your problem.

[Attempted TWRP Soft Brick] Can you please help me recover from soft bricking my GS5?

I rooted my phone about six months ago so I could have super user permissions. Today, I decided I wanted to try to install cyanogenmod.
After following the instructions to install CM and repeatedly failing (with no apparent harm to the phone), I thought the issue might be that I hadn't unlocked the bootloader. I tried to install TWRP using Odin, but apparently I had installed safestrap back when I rooted. I opened safestrap, attempted to install the packages listed on this post [http://forum.xda-developers.com/ver.../rd-unlocking-galaxys-s5-bootloader-t3337909], and my phone is now apparently/maybe softbricked. I tried to follow the un-bricking instructions on that same page, but I'm getting "fail" messages from Odin.
I do not know what I'm doing. I downloaded what I thought was the stock TAR for my US Verizon Galaxy S5, but it's giving me fail messages when I try to install it with Odin in the AP slot. Am I missing something? Do I need a Pit file or something else in the BL or CP slots? What am I missing?
I would really appreciate any help. I'm out of my league with this.
To add information, I'm getting an error message on my phone saying "[aboot] fused 2 > Binary 1 error" and even after googling that I'm not sure what the fix is.
I just want to get back to non-bricked. Even stock is acceptable.
Go to Sammobile. Com and download ok3 or PB1 firmware for s5 verizon and flash it in odin to your phone

G930V (custom rom) to G930A_BRA1? help please

Hey I'm on a custom rom for my Galaxy S7 which is originally an AT&T variant however I've had many different firmwares on here. I'm trying to go back to AT&T and the firmware file I'm finding on here is a 7z file. I tried extracting it and even removing the .rar from the end however PrinceComsey Odin doesn't process is farthest it gets is file analysis. Are these just bad files? Am I using the wrong Odin? Am I extracting it wrong? Are there other requirements? I can follow directions just fine and usually it's pretty simple

Conf00sed n00b needs to restore his 950u to fac

hello, not exactly a n00b, but definitely with this phone.
Long story short, tried to root with Odin using apparently depreciated instructions. Odin halted after wiping my NAND, leaving me with a softbricked phone.
I need help restoring the phone to factory. I have expierienced fail auth and sha256 errors trying do restore.
Which of the dozens of flavors of odin , and which FW do I need to get this back to work? I forgot to mention the carrier is AT&T. So my boot loader is locked.
TY
use prince comsy odin

Clarification
Is U1 FW the same as for SM-G950U? Just want to clarify before I attempt to flash again. and ty for your reply
Restore worked beautifully, however cosmey errored out and I had to use the PatcheD version of odin to complete. Can someone point me to a guide for rooting the U1 oreo pls?

U 1 can be flashed but you just want the regular U firmware.
Make sure it is the correct bootloader version as what the device is on now or higher. As downgrading is not possible and also throws a fail auth error.
Also use regular Odin 3.13.1 for stock firmwares. Not comsey,that is for modded firmware and such

Yea here's the kicker. Oreo can't be rooted and u1 isn't rooted only rooted is part cyborg rom. Which is U Firmware Also if your bootloader is to high. 3 or higher no downgrade no root
I think we have had quite a mix up or misunderstanding here...The link in #2 points to ATT SM-G950U1 FW. I looked all over the sammobile site and was not able to find any ATT FW for the 950U, only the U1. Also, I was told in #2 to use prince cosmey so I tried. I ran cosmey as admin loaded the 4 Files, left the options on default, and it errored out. So I tried standard odin with default options, it errored out as well. Finally, I used the PatcheD odin 3b and it worked flawlessly. My only question now, can someone link me to a working root method for the 950U/U1
for the snapdragon version of the s8 by at&t? I have tried several, but odin and/or the device always throws an error. I am on the verge of giving up. TY very much for all your help up to this point, I could not have gotten my phone back to working order without your help.
