Just bought a used Tab, cant get past the activation screen? - Galaxy Tab Q&A, Help & Troubleshooting

I just bought a Samsung Tab for 140 bucks.
Model # sch-I800
I think it is a 3G tab but I bought it because I only want it for wifi use only and the previous owner said it could be used wifi only. When I turn it on it asks me to activate it and when I hit the activate button it says unsuccessful.
Do they have to be activated? If so how?
thanks in advance!

Nevermind. I figured out how you can bypass the activation screen using a certain sequence of the volume butttons. So I'm up and running now.

Does the tab need to activate after rooting or rom flashing? I have no data plan.

Hi everyone. To date, I've rooted every Android phone my wife and I have owned (and several for other people). I bought a Verizon Samsung tablet today and of course I want to root it. The tab was used and the girl I bought it from did a factory reset BEFORE disconnecting it from her data package. I noticed that the tab went through an activation process after the reset. Everything works fine on it now, except it's stock and not rooted.
I'm not sure if rooting this thing will require me to activate the tablet. I haven't researched to see if the software is replaced or if it just pushes super user to the tab but I'm pretty sure flashing a rom would require the initial activation set up.
So my question, if I root and rom my tab and DO NOT have a data plan, will I be able to get back into the device? I asked Verizon what would happen if I did a factory reset (which is the same as wiping data in recovery) and they said I could temporarily move one of my phone lines to the tab...which is also a problem because we have 2 Thunderbolts. If I transfer my line from the phone, my sim card will be no good. I'd have to go to Verizon to get a new one.
Any way to bypass the initial activation after a factory reset or rom flash? Or is that even a problem for rooters without data plans. Am I over thinking?
No one?

Thanks, I found something online saying that I can press the following at the activation screen to bypass it:
Vol up once
Vol down twice
Vol up three times
Vol down four times
I'm yet to try it but I will this weekend.

How to use Verizon tab w/o acct?

Sorry in advance for the nooby question. I just cancelled my Verizon plan for my Verizon Galaxy Tablet and have someone who wants to buy it to use as Wifi only. Is there a way to do this? I reset the tab back to stock, but now I can't get past the activate screen. How can I convert this tablet to wifi only?
When you get to the activation screen press the volume button in this sequence.
UP, DOWN DOWN, UP UP UP, DOWN DOWN DOWN DOWN
A new menu will appear allowing you to skip activation.

Milestone (no sim) (no service) screen

Hi i recently bought a Motorla Milestone off craigslist. Upon turning it on I am prompted with a screen only allowing me to make emergency calls and nothing else. The screen also says no service no sim. My question is can I bypass this as I only want to use it over wifi. Or if not what can I do to use this phone would puting a unactivated sim bring up the normal activation screen?

Perform a factory reset of the phone that should get rid of the screen only allowing you to make emergency calls. And yes putting a normal unactivated SIM should bring up the normal activation screen if not I believe you dial *228

I haven't gotten around with it yet. The last time I tried, I got the Security Exception. For now I just bear with it, I boot my phone and do something else so that I won't notice. haha.
Will follow this post just to be updated.

Mine never does that. Does it succeed? It must succeed to not pop that up.
One thing I've learned the hard way several times, is if you have AdBlocker running it screws up Activation, Update PRL etc. But you should be able to turn it back on later.
If it is failing activation even with adblocker off try activating with WIFI connection up.
You can also try ##72768# but be warned if it does not succeed you will have no voice or data. I recommend doing this only with a solid Sprint Signal 3G or 4G, but WIFI will work too.
If you call sprint, 99% sure that's the first thing they will try.
If you are using GSM in another country there is an app you can freeze. Look in Sprint M9 forums, this is asked all the time on how to kill it.

I'm on GSM in another country. I tried methods described before to turn it off before, but I ended up bricking my phone. If I started to be bothered by it again, I might try freezing it. Something I noticed though, I didn't notice the Activation prompt on my recent reboots recently.
For the information of all...
Dont try remove or Rename "LGStartupwizard.apk" remove this APK cause Bootloop and stuck at the "LG Security Error" and the only way to go back to life the G4 is flashing TOT file
cheers!
It might be wonky activating because your on a gsm network with a CDMA based phone.

Galaxy S8 financed blocked?

I bought a used t-mobile galaxy s8. The website I used said clean imei and I put my sim in the phone and it worked fine. After taking it home it stopped working. I played around with the settings to get it work and came to find that it works briefly after turning phone off and then back on. After about 10 minutes I can't make call or even perform a speed test via speedtest app. The dialer screen will not even load and remains blank, then no calls incoming or internet. If i restart then it starts again. This made me suspicious and I eventually found the t-mobile imei site which says it has an outstanding balance and may not be able to be used. I just find it weird it works then stops. Is that what is causing it? Will it eventually stop working completely?
call tmobile and describe your issue. they can help or at least tell you what to do.
OP, where did you buy the phone from?
I purchased one from S**p*a and have similar concerns.
I recently had the same issue.
I found out somehow an option was enabled that made it seem like i was network blocked or had a bricked sim card.
Under settings/connections/more connection settings/wifi calling
Make sure the middle option is selected and not "never use cellular network"
For some reason every samsung phone i have owned has enabled this option atleast once during ownership.
