[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] Mike_SattyEng:
All, I have an AT&T Samsung S7 Edge (G935A) I have had for about 14 months. It is bone stock and I have always applied every OTA as they are pushed to the phone.

Three days ago I got the notice for a software update (4BQL1). I downloaded the 45 Mb update and told the phone to reboot. Upon rebooting the update installation got to 26% and then stopped with the message "installation interrupted". I tried the following fixes but nothing worked:

1. download and reapply update

2. Power down and restart in recovery mode then clear the cache. This was recommended AT&T in one of their forums for a previous update.

3. Factory reset and then restore of my backup settings.

These failed!!!!:crying:

Next step was to take a trip to my local AT&T corporate store. After 2 hours their only recommendation was to go home and use the Samsung Sync App on my PC to try and install any updates. I backed up my phone using the Sync app and then had it check for an update. Sync reported the phone to be on the most current firmware (4BQK2) which was incorrect.:crying:

Here is how I fixed my phone.

1. downloaded most current rev of Odin (3.12.3) I got from this website: https://odindownload.com/

2 Downloaded the full version of firmware 4BQK2. Note this is a 1.9 GB download. Thank you Norab for your post. https://xdaforums.com/att-s7-edge/how-to/updates-g935a-servers-adb-sideloads-t3583165

Instructions:

1. BACK UP ANY FILES ETC YOU FEEL ARE CRITICAL BEFORE YOU START! (I used Samsung sync app on my PC with it connected to my phone). This install will ERASE all of your files and reimage your phone. Note: I am not responsible for your actions if you fail to heed this warning or you brick your phone.

Extract the 4Bk2 zip file. It will have 4 RAR files with BL, AP, CP and CSC appended to the file names. Use your favorite RAR app (I like 7 zip for windows) to extract the files into 4 folders. Each folders with will have one file with an .md5 extension.

2. Power down the Phone. Connect it to your PC with a USB cable (this assumes you already have drivers installed) and then restart the phone in update mode: Home button + Power button + Volume down button. You will need to follow the screen prompt and press volume up to enter download mode.

3. Launch Odin on your PC.

4. Verify Odin is connected to your phone via the USB cable. Odin will indicate this by showing a Comm port number in the upper left.

5. In Odin click the BL, AP, CP and CSC buttons (one at a time). This will a windows folder. navigate to the applicable folder and select the file with matching prefix (BL, AP, CP or CSC) then click Ok. Watch the log window. Odin will inspect the file and verify the MD5 hash. Odin will tell you if the file ok or if it is corrupted.

5. Once Odin has verified all four files, click start.

6. You will see a progress bar on your phone. If you left Odin at the default configuration it will restart your phone when the last file has been copied to your phone. Odin will display "PASS!" in the status area right above the comm port.

7. Wait for the phone to go through the installation process, you will see the AT&T globe for a while. This will take some time to complete. You should finally see the phone screen state "installing applications". Once this completed you will prompted to set up the phone.

8. Set the phone up as prompted.

9. If you backed up to Sync, now you can use it to restore all of your settings, apps etc. Otherwise log into your Samsung account and it will restore all of your settings over the air assuming you had previously configured your phone to backup your Samsung and Google accounts.

Once the restore is completed and your phone is stable, check for new updates. My phone showed me an update was available (4BQL1 in my case).

I downloaded the update and it installed correctly. :o:o:o:o

Good luck!
