[Galaxy Tab 7.7 General] Gilbot:
If anyone is like me and owns a Verizon variant of the Galaxy Tab 7.7 (SCH-i815) then you have probably noticed that there is little information for users here that is easily available to refer to that is specific to our variant. This post is meant to house information for reference and I in no way claim to be the originator of this info, all props go to the creators themselves (please let me know any missing info so as to credit the proper people).

Please also let me know of any corrections that need to be made. If anyone feels this should be in the development forums, please don't recommend it to be moved, I am not a developer.

PLEASE BE ADVISED THAT ALL INSTRUCTIONS AND FILES HERE ARE FOR THE VERIZON GALAXY TAB 7.7 LTE SCH-i815

ONLY

AND THAT YOU USE THIS INFORMATION AT YOUR OWN RISK.

If you have a different variant, do not flash any files below or you risk bricking your device .

As a general rule,

DON'T ACCEPT OTA UPDATES IF YOU'RE ON A CUSTOM OR MODIFIED ROM

. They will probably fail to install and remove root access.

SCH-i815 OFFICIAL FIRMWARE(S)

None available at the moment (probably never tbh)​

*BE CAREFUL! No known official firmware exists to return to stock! Don't bork your Tab!

FAQs

Q: I obtained a Verizon Galaxy Tab 7.7 without a contract and have a 4G LTE phone with a compatible microSIM, can I swap the microSIM from my phone into the Tab and get service? What about Phone calls and SMS/MMS Text?

A: Yes and No. You can place your microSIM in the Tab and data will work. You can't, however, make or receive phone calls and SMS/MMS text as it has been disabled by Verizon. The APK files don't exist and simply using a file explorer to install them from the P6800 won't work. You will receive endless Force Closes and soft reboots if you do. There is no known way to enable Phone and SMS text at this time.​

Q: Does the 64gb MiscroSDXC card work in the SCH-i815?

A: Yep. Make sure to format it in the Tab before loading it with files. It is possible to format the card with an NTFS filesystem, for more info: http://xdaforums.com/showthread.php?t=1665491​

Q:I have CWM installed and am Rooted on

stock rom

but I want to return my recovery to Stock in preparation for an OTA update, how can i do this?

A: Please check out electron73's awesome guide to revert back: http://xdaforums.com/showpost.php?p=27376275&postcount=7. This guide is for trying to update from build FA02 to FD01. Not sure if this will work in any other situation.​

Q: I updated my Tab to ICS and don't have service with Verizon (I plan to use it as WiFi), How can i stop this annoying "SIM not inserted" notification?

A:There are a couple things you can do to stop this annoyance:

1. Insert a Verizon LTE SIM and allow it to activate if you have service with Verizon or allow it to fail activation if you have no service with Verizon. You can then turn off mobile data in Settings>Data. Leave the SIM in your tab to avoid the annoyance.

2. If you have no Verizon LTE SIM, put your tab in Airplane mode, then enable WiFi in Settings>WiFi. You should also be able to turn off mobile data in Settings>Data.​
