please help me with downgrading verizon galaxy tab 10.1 from ics to honeycomb.

Hello, today I upgraded my verizon galaxy tab 10.1 from honeycomb to ics with customized rom.
I knew here would be one or two problems, but after I upgraded my device to ics, it just disabled using data.
What I mean is that there is no symbol or any option that allows me to turn on my data or whatsoever.
The rom that I used was AOKP, milestone 6.
Someone please help me to get back to honeycomb.. please!!
I'd reboot into recovery, factory reset, reboot into download mode, then flash factory ROM with Odin. Make sure you backup your data first.

WiFi stopped working after flashing resurrection remix Rom

Hi,
So I got my first problem while flashing today, have played with roms and things on my s3 a few times and dispute being a noob never had any bad experiences.
Earlier today I decided to root my note 10.1 gt-n8010 (uk) which also went fine and no problems, I then decided to try a custom Rom after I wasn't that impressed with the ota jelly bean 4.1.1 update and flashed resurrection Rom with the jelly bean 4.1.2 via cwm to see how that stacked up. However on the first time I ran it I noticed I couldn't connect to my WiFi anymore, I rebooted my note to see if that would help but it didn't.
I can get into the WiFi menu ok and fill in my WiFi code ok, but them just get a message saying 'failed to connect to WiFi'
So has anyone else had this problem or know of fix for it because as you can imagine is quite annoying, if there is nothing I guess I have to flash another Rom?
Thanks in advance guy's, I appreciate any advice
I would suggest flashing CyanogenMod nightly, it has the latest Adndroid version 4.2.1 and it has very few bugs.
Suggest wipe and flash .
Redemption works UK wiFi .

[Q] Sprint Galxy Tab 3 Root issues

So I rooted my Galaxy Tab 3 and tried flashing the Goodness rom since it was the only I could find for this model. I used CWM to backup everything before hand. When I booted it up after the flash my wifi wouldn't turn on. So I decided to restore my backup of the stock. Well it got stuck at the Sprint boot screen so I had to use Odin to put it back at stock. Now it won't connect to LTE, wifi still won't turn on and I need help getting a working rom for this thing. Does anyone know of any stable roms that don't cause these issues?

Custom ROM Flashing Problems

Good day to all, ya'll have changed things a bit it appears since my last visit. Okay I don't know what is going on as I have flashed hundreds of ROM's without issue and this morning Im seeming to have all kinds of issues. Sprint Galaxy S4 rooted and Flashed for Straight talk network. I am having some kinds of problems and am not able to flash any custom ROM's. Ive tried flashing GPE 4.4.4 and Super S4 ROM and Im getting a Footers Wrong error, error #7 and Signature not verified error and then it will reboot back to the stock firmware. So being my bright self that I am I toggled the signature deal in Clockworkmod and flashed it again and the phone rebooted and started up in GPE, but I could not get a data signal nor would it allow me to even turn on the wif-fi. and now Ive got it bricked and hooked up to odin. Any suggestions, comments, beatings or there of the likes. lol thanks guys yall are great.
Custom ROM Issues
Okay good day once again....Okay the phone has booted up completely and with GPE 4.4.4 or what I assume is GPE. I have no service to the device what so ever, but it does saying preparing network in the task bar and has been saying that for 20 minutes now, I still can not turn on Wifi. When I go to about device it says the following Software Version - Unknown Hardware Version - nothing Android Version 4.4.2 Baseband Version- unknown Kernal Version 3.4.0-216929 [email protected]#1 Wed Jul 9 09:03:50 2014 Build Number - SuperS4-1.5(which means it isn't GPE it is Super S4 ROM, which is cool especially since one of your guys I think built it) and everything else their looks normal to me. So any feed back on this post please. I have to be at work in a few hours and can not do without a phone ....
Hello...! I have some questions to you.... Do you try to flash a custom rom from recovery right....?
And it says "status 7 error"?
I think the reason for this is that you are trying to flash a rom that does not match with your phone or it's not singed...! For example you are trying to flash a rom for Samsung Galaxy S 4 GT-I9500...
