3g 1x disconnects - Fascinate Q&A, Help & Troubleshooting

So I was rooting around in the hidden menu the other day (i know, don't say it) and now my data disconnects completely and randomly while using any app that requires data.
I have tried full wipes to no avail, and have already tried re-flashing the radio. It also disconnects every time I initially launch an internet app, then wait about 30 seconds and its good to go for about five minutes then the same happens again.
This is so frustrating, does anyone have any idea what to do with this thing? Will an all in one Odin undo whatever evil I have done, or is there a way to "reset" the hidden menu to default.
Edit: And i have searched high and low on this and found nothing. Please don't patronize me with "read first" posts and the like. I am not new to these forums and am very familiar with the rules.

You need to DMU reset. Only way to do that is to ESN swap. So if you have an old phone laying around, activate that wait about five minutes and the reactivate your fascinate.

Crazy trackball

Hello xda crew I have a problem with my phone. Over the past few days the tractable has become possessed. It will scroll to the left whenever it feels like it and it won't allow me to recenter until I screw around with it. I tried dust off but nothing. Can I drop a lil alcohol in there to clean the contacts or flash back to 2.1 and go to Verizon?

Im having the same problem. When it does it i just shut my screen off and roll it all around a little vigorously (not to hard) then it fixes it for awhile. Its what i had to do back in the day when i had a blackberry with a trackball. Actually it is what the blackberry techs told me to do. Maybe if it doesn't fix we can unroot and get an incredible or something.
I was thinking droid x but i guess incredible would do as well. its still annoying though. I wanna pop the phone apart but warranties are so much more useful when you dont void them

Phone is bricked, here's tmos take

I have a Samsung Vibrant. I had installed Assassins Creed, NOVA, Geocaching app, did the GPS fix from the secret screen. This is all pretty much stock stuff, I've only had the phone a month. This morning I woke up and it said "THERES AN UPDATE TO YOUR PHONE". I was like ****ING A RIGHT THERE IS. So I clicked next and took a shower.
Phone is stuck at the VIBRANT - SAMSUNG Screen. Since I had been in the bathroom about half an hour for the three Ss, I know it had half an hour to get this right. Rebooting the phone gives me the happy crappy jingle (yeah, still stock jingles) and then the phone hangs. Accessing the (stock) system restore screen and clearing both user and cached data did nothing, so I grabbed my kid and went to the Tmobile store. People tend to be more helpful when you're annoying them with babies.
They did the same thing, then they got on their super secret tech support line. The guy did a lot of Mmmhmming and reset the phone a few times and said it was dead. Then he handed the phone to me. They asked if I overclocked the phone with voodoo (something or other). No. They asked if I had task-killers installed (Advanced Task Killer) and if it was set to kill anything automatically. I said no. They asked me what I had installed since I got the phone. I'm not a poweruser here, I hadn't really had the time to dig into it nor the inclination figuring the update was in the pipe, so I gave them a list. I asked if they could see what was installed, she said they could not, hence the questions.
At this point they offered to ship me a new device, and lent me a new phone. The shipping, unlike other laments on the forums, is free IF you don't take their offer to upgrade.
I got off the phone with them and let my kid eat the displays for a bit - apparently I'm *phone number four* they've had come in today to be sent back. Tmobile knows they have an issue and they are replacing the phones for free so long as you're not that far off the reservation. Now, I'm guessing there's not four people who read these forums and mess around with their phones out here in the sticks, so even the stock phones are getting killed here. If it kills my wifes phone (and she is absolutely stock, GPS crap and all) then I'll know there seriously is a problem. The technician advised me not to update the phone until further notice, I'm inclined just to be a PITA and keep doing it as motivation to at very least pull the update.
Damn that is awful. I was under the impression only rooted phones with laxfixes and/or different kernels were screwing up the update. I wonder if someone, somewhere, is getting fired over this fiasco LOL. Four phones replaced in one day.....

Just to be fair to tmobile, it was rooted. I had titanium backup on there to uninstall the meego stuff, the in flight internet stuff, the sims 3 (170MB if I recall correctly), AVATAR but the goal was to uninstall the stuff that was clearly advertising and such. It wasn't taken to the level of having TEH NEXUS WON or a "Stock ROM".

Looks like getting the battery replaced isn't all that complicated at all. Maybe some company will even come out with a different plastics to accommodate a larger battery.
The guy in the above linked video actually removes the battery within three minutes and forty-two seconds.
That is very fast considering he was even narrating how to do it at the same time. I think I will send this to a few battery manufacturers to give them an incentive to create an aftermarket battery.
Thank you. I believed this could be done in theory. I even created a post about this and everyone was like, "No, you have to remove the screen and then that just gets too complicated." Actually, all you have to do is pop off the back with a flat head, remove four screws, separate the back plate and bam, remove battery and replace it. Takes all of about 3 minutes.
Since the phone is so thin, I wouldn't mind replacing the 2,000 maH battery with a 2,500 or even 3,000 maH battery with just a little added thickness. As long as it is no thicker than my Samsung Epic 4G. That is about perfect thickness. Anything bigger then I will just use a car charger or something.
So what happens when we get to that step in the root process or bootloop that says
"Remove Battery"?
Ugh.
Is there a hard reset button?
may be a hard reset button. but more likely it'll be like One X where 10sec power button push shuts phone off, then power and volume can be used to get to bootloader.
god, i hope i never have to pull my phone apart like that. watching that, I realized the whole time my muscles were clenched, and spine taut as though watching a life or death human surgery.
The one thing about getting this phone is the scare of not having the Non removable battery. I mean sure there's a hard reset, but we had one on the EVO 3D and 10% of the time it didn't work. Not to mention if you flashed the latest firmware leak its completely hindered and won't work anymore... So small things like that can be worrysome

A nice thing I learned while using my HTC Jetstream, which also does not have a removable battery is that if you ever end up in a bootloop, adb still works. So I always end up just doing an "adb reboot bootloader" to get out of a sticky situation
^ I was wondering when someone would pipe in with this bit of info. It works, very well. I wasn't worried about the sealed battery because of ADB. Maybe if more people used it (Meaning: Don't use a one click method, if possible. Learn how your phone works. If I'm 20 and can figure it out, so can everyone else.), we wouldn't have as many people asking questions they could easily fix themselves.
Once, long ago, there were no one click methods, and you had to do it yourself. (No, I wasn't Androiding then, but I wish I was.) If anyone else came from VZW and remembers the Fascinate (Galaxy S variant) some people couldn't get one click methods to work and had to do it manually. Setting your system partition as R/W for the first time, by your own hands, is very rewarding... especially with a Samsung phone.
Boot loader tools are a different story, but there is no reason anyone should not be able to at least root a device themselves once an approved method comes out.

I hear ya, I too am also only 20. I have to admit, with my HTC EVO 4G, I did use a one click root method to get where I am today, but when it came to my HTC Jetstream, that was a different story entirely. It had a locked bootloader and the root process was a bit more tedious. With that being said, I have to admit, I learned a lot more while using my Jetstream.
I think manual method is a whole lot better. You actually learn something instead of just mechanically clicking a button, not knowing what is really going on in the background.

In essence, on-click-root is for those Apple fanboys who want an automatic jailbreak, and DIY is for those hardcore Android mechanics who root like a bawss.
^^Very well said above! Seriously though, i truly hate the one click stuff because I don't really know what's going on behind the scenes.
For the original evo, there was a how to guide that was all manual. I went over each step until it was clear what was being done and why.
I'll admit, forbmy Incredible, I used a one click method, but I was curious about how it worked and investigated. It wasn't until my Fascinate that I actually needed to use it, but like I said, I was curious. I feel its important for rooted users to understand at least part of the process. It is an eye opener to a fraction of what our devs go through. It gives you a deeper appreciation.

PLEASE HELP. Phone wont turn on.

So, I rooted my GS3 with this method http://www.youtube.com/watch?v=XoEVD...ure=plpp_video
Everything went perfectly and was successfully rooted.
I then made a backup of my phone.
I tried installing a rom and it had errors, so I restored my phone and it was successfully stored and hit restart phone.
Thats where I am at now. The phone shut off, and wont turn back on. I have it on the charger and there is no charging light, nothing. tried pulling the battery, entering recovery. Nothing works.
I have no idea what happened or how to get my phone back on.
Please help.
Thank you.
Sounds like someone installed an International rom.

if you did flash an international rom, did you follow all the suggestions in this thread during your recovery attempt:
http://forum.xda-developers.com/showthread.php?t=1727443
The seriousness of your issue will depend on if you can enter download mode or not. Do not have USB connected, pull the battery and put back in to make sure it is truly off, instead of some hung state of "on". Hold Power, Volume Down, and Home at the same time, for several seconds to try to enter download mode (see http://youtu.be/0BJlfbZNB-I).
If you can get in, you should be all set.
Then open up Odin (http://samsung-updates.com/Odin307.zip)
Connect USB, it should light up a "COM" port recognizing the phone as connected.
Find the proper stock tar file for your carrier:

T-Mobile: http://forum.xda-developers.com/showthread.php?t=1737855
Note, the sprint one also has a video link to similar instructions.
If you can't enter download mode, however, that's a potentially tough situation. You may research "jigs" that I'm not familiar with, or you may consider a warranty return, an often debated morally questionable move.
Let me save you some time..
As said, see if you can get into download although if no charging is happening i'm 99% sure theres no download mode either. In which case plug it in your PC. If it appears in device manager as QHSUSB DLOAD then let me be the first to say,
WELCOME TO BRICKTOWN. sorry but you look like another unfortunate person to see how easy these ****ers brick. my deepest sympathies
Also, in reference to the jig, unfortunately does nothing in this situation. I feel confident though that somebody will eventually find a way to unbrick with the Qhsusb dload brick because i saw after hours of looking into this it has been done with other phones. just my 2 cents
So, what I ended up doing is returning the phone to best buy for an exchange.
Now I know to pay attention and not install international roms anymore. Lol
Thanks for all the help though.
Oh, and my phone was not able to enter download mode, so I was assuming I was screwed for the most part.

These company's do care, and why do you think they lock bootloader and constantly patch to prevent rooting , samsung has been easy so far but, given enough returns and complains from retailers they will change their policy. Just a matter of time.
Samsung also implemented flash counter just for this reason.
Sent from my SAMSUNG-SGH-I747 using Tapatalk 2
Couple things. People work for Best Buy and anytime you defraud them it will impact the company, the profitability, and employees. It will also eventually impact people who have honest claims and get put through the ringer because of previous claims.
Secondly, this phone isn't any easier to "brick" than any other phone when you flash a rom, modem, etc. that wasn't made for it. Would you try to chip your Ford's engine with a chip meant for a GMC truck? Would you flash the BIOS of your Dell laptop with the BIOS image for an HP? That is how people need to consider the variants, as if they are from separate companies, not only separate products.
These threads just get under me. How do you not read every single sticky on each board.
Hmmm, wonder why Verizon got the idea to lock the bootloader?

[MOD] GPS Fix....Faster Location fix.

I recently went to West Virginia from Ohio and noticed the GPS took forever to get a fix on my location. I changed the GPS file and it went from taking 5 to 10 min to get a fix down to 5 seconds or so. I figured it might help others out so feel free to try it out.
This is for the Sprint S5 but may work on others I'm not sure. Test at your risk.
Use root explorer or a file manager with root access to rename gps.conf.txt to gps.conf then copy it to System/etc/ folder. Make sure the permissions are set to RW-R--R-- and then reboot.
PLEASE MAKE A BACKUP OF YOUR system/etc/gps.conf FILE FIRST JUST IN CASE.
This is what I added to make this work.
Will work on most androids and thanks for hitting the Thanks Button Everyone

Glad that it worked for you and thanks for putting info on what your device is.
Thanks for providing this fix. Unfortunately, I tried it while on several AOSP ROM's available for the Sprint version and it seams to have broken GPS.
Prior to applying this fix on AOSP based ROM's, GPS worked and locked fine, afterward, It's stuck on "Searching for GPS" and won't lock on.
I've tried everything I can think of and the only way I can get it back is to restore my nandroid of my rooted stock TW based ROM. Unfortunately, I didn't nandroid after flashing the AOSP ROM's when GPS was working. I've tried 3 AOSP ROM's (Carbon/Vanir/AOKP) and all 3 have the problem.
Any help in solving this would be appreciated.

I don't want credit for it. I don't want credit for anything I didn't do. If you read the entire thread, you'll see that I had just cobbled together something I found here and there on the internet. Even if I did package it, it's still not my idea.

Hey thank you this works pretty good! Much faster GPS lock. Can it be taken 1 step farther and default to California instead of North America?

You should be able to if you have the server settings for that location. Just put them in place of the North American ones.
Just Flash a stock Samsung Firmware through Odin, or Heimdal If you have a mac. If your on the latest firmware you cannot downgrade so do not waste your time flashing any other firmwares via odin. After you flash stock via Odin boot the phone let it get a GPS fix and then flash the ROM of your choice [unless it has known issues with GPS fix this should solve your issues] Take care
Alright so.
I flashed this GPS fix and ever since I did, my data connection bounces all over the place, even after I went back to stock?? It really borked my system.
So, the GPS didn't fix... As I couldn't get a lock in the first place. Secondly, my data would no longer connect. I was smart enough to do a backup of the system BEFORE flashing this fix file, thinking it would have backed up the original GPS config file, though maybe in crazy and always had acted like this? Then I factory boot back to stock, then got a boot loop, tried a couple times, ram the rwilco rooted rom and booted in, got my GPS lock, did the battery pull and restored my backup.
Had anyone else experienced this kind of issue? It's now functional, aside from my data signal constantly flaking out on me...As dumb as i was, I did not actually back up the original sprint file, separately wishing i had. If anyone has it, please post it up , it would be greatly appreciated.
Would love some feedback, thank you!

Use root explorer or a file manager with root access to rename gps.conf.txt to gps.conf then copy it to System/etc/ folder. Make sure the permissions are set to RW-R--R-- and then reboot.
PLEASE MAKE A BACKUP OF YOUR system/etc/gps.conf FILE FIRST JUST IN CASE.
This is what I added to make this work.
Will work on most androids and thanks for hitting the Thanks Button Everyone

it's working pretty fine buddy.. thanks
Okay, that's about enough.
I'm just going to say it. This fix appears to be the cumulative product of lots and lots of cargo cult nonsense. It's unlikely to ever help anything, no matter how many people have been posting that it "works great". To someone who is familiar with these technologies, upon close examination this "fix" really sounds a lot like a bunch of people on the internet got together and came up with a cure for the common cold which involves filling a Neti pot with Oscillococcinum, and then gently inserting it into one's rectum. This "fix" is wrong for a positively breathtaking number of reasons. Making matters worse is that it's gone on for so long that a whole bunch of well-meaning (okay well, "desperate for clicks" is probably more honest) blogs and news sites are repeating it, also without examining it carefully. Can we please stop spreading this misinformation around?
First off, those NTP_SERVER lines are unlikely to be doing what is apparently hoped for (I can't be the only one thinking it)... they're setting a variable--not populating an array. It's just replacing the previous value seven times. This means the last value "wins". Secondly, to do NTP properly there should only ever be an odd number of NTP servers involved. Eight is not an odd number... unless you're using Imperial eights or some eights you got off some sketchy Chinese website or something and then god help you. In the event that there's a disagreement among the servers polled, the time reported by a majority of them is what is used (because it's NTP which is a protocol that has been argued to death since before many of you were born, so that's is a fight you would do well to not jump into the middle of). You can't have a majority if four are saying one thing and the other four are saying another thing--you're just dead in the water and have to start over. We don't average the responses from all of them because that would definitely be wrong, despite being "close". It's also appropriate to wait for them all to respond before making this determination. If you try to poll eight and one doesn't respond... there's going to be considerable time lost while deciding it's not going to respond. Using lots of servers just adds complexity and the chance of failure without substantially increasing precision! Compounding this madness is that the pool server names are all querying from the same pool of NTP servers, despite one set saying "north-america" and the other saying "us". The best part is that it's primarily being used to ensure that the time your phone already has (and probably got from the cellular towers) isn't wildly inaccurate. What matters to GPS receivers is the time the satellites think it is (which is generally even more accurate than what you're going to get over the internet!)
Now, we do need to know the present time to get a result more quickly, but we don't need femtosecond accuracy for this, nor would specifying a whole bunch of NTP servers make that possible. We just need a ballpark figure that's accurate to within a few hours. We need to know the time so that we can use ephemeris tables (that's the weird file your phone occasionally downloads from the internet and is good for a few days--don't waste time re-downloading it multiple times a day!) to figure out where the satellites are in their travels, and we're just (pretty reasonably) assuming that no one crossed half a hemisphere since the last time GPS was queried, so... knowing (within a few hundred miles) where we are and where the satellites are, we can work out in advance which servers are most likely to be overhead and visible/audible. This allows us to skip listening for a bunch of satellites we can't hear, (and most importantly) exclude the borderline useful ones near the horizon that we probably won't be able to listen to for long enough to be useful. because of interference, and go straight to listening for the ones we can be pretty sure are overhead in relatively ideal positions.
Now as to "pure" GPS mechanics, let me explain... You need a minimum of three satellites in "view" in order to get a solid fix on your location.... because triangulation isn't something that happens when one tries to swallow a Dorito without chewing. There's be a whole slew of the satellites flying around overhead and things can get very complex very fast, but you still need three to triangulate your location. Additionally your device has to be able to "hear" them for about thirty seconds in order to get their broadcasted location information (which is almost ridiculously precise because getting it wrong can mean falling out of the sky LOL and satellites aren't cheap!). In that time we are also getting what time the satellites think it is with (no pun intended) stellar accuracy.
Your phone uses ephemeris tables and (hopefully) an almanac of satellites it's heard from recently to skip the step of finding three satellites to listen for, and it uses cached time information to skip ahead again instead of waiting for the part of the broadcast with time in it. This is why you get a coarse location within 100m or so really quickly, which is then refined as the satellites' time is heard and perhaps a few more satellites are listened to for good measure. Most of the poking and prodding people are doing (particularly those which flush the almanac or cached location information) tends to actually just slow things down, not speed them up.
TL;DR: Stick with one NTP server in your gps.conf. ...preferably north-america.pool.ntp.org (the numeric host part you see it prefixed with is also largely decorative) if you're in North America because it's better for determining accuracy and less wasteful of public resources. NTP servers that are overworked because people are querying them needlessly can't respond as quickly as ones that are almost bored to death.
To those people who seem to be convinced this "fix" works, please perform the following experiment. Back up all your data and wipe your entire phone (wipe caches, format /system, nuke user data), and then reflash the firmware. Boot it up, go into Maps, and time how long it takes to get a solid location fix. Now, reboot the phone and while it's rebooting, place it in the middle of a large plastic (not metal) bowl filled with Doritos. I personally prefer Cool Ranch flavor for this. Once it's rebooted, again go into Maps and time how long it takes to get a solid fix on your location. Congratulations, you've just proven that Doritos have an almost magical effect on the accuracy and speed of the GPS receiver in your phone by assisting with triangulation! Please remember to chew thoroughly when the experiment is complete.
