[request] WIFI Only Rom - Epic 4G Q&A, Help & Troubleshooting

ROM that doesn't use any resources or have any apps for phones or mobile connectivity. I need a ROM that's strictly for web browsing when connected to WIFI.
(I lost my phone and deactivated it and got a new one. I recently found the phone and since its deactivated its only useful when connected to wifi)
So I would like a rom that completly rids of th ephone features and just have a "portable internet / gaming device"
Will pay handsomely if a developer is a redditor. and makes a rom with my request, but in mind "Reddit Moblie"

Umm... just use airplane mode on any rom, even stock and there ya go.
Stock should let you activate Wifi with airplane mode activated, but some custom roms do not. There is an app in the Market that allows you to activate other radios, like wifi/cell/bluetooth, with airplane mode active. (Here)

I think tphillips was his name...he worked on something similar, but it's been long abandoned.

I keep the cell radio active for syncing the time... You can root and use an app to do NTP... but the cell radio sync is easier, especially if you cross timezones since it will resolve that automatically...
Also, leaving cell connection on allows you to use Llama location profiles as well.

Why does mobile hotspot work but others don't?

I have a Verizon Samsung Fascinate phone and an Acer A100 tablet. My tablet locks in on the wi-fi signal generated by the the Fascinate's Mobile Hotspot program with no problem, however it does not even recognize the wi-fi signal generated by Open Garden Wi-Fi program.
Does anyone know what the Mobile Hotspot program has that Open Garden Wi-fi program does not?

If by Hotspot program you mean the carrier loaded one, then this makes sense. This tablet only supports a specific wifi range (called ad-hoc I believe? Correct me if I'm wrong here) and thats the signal type the default one gives off. But OpenGarden uses a different one (called ad-poc I think, again correct me if I'm wrong) and the tablet doesn't support it. So your solution would be:
1.to try the beta version of the normal wifi tether app (the one that opengarden is built off the sources of, you know the one.) and see if that fixes it.
2. switch to an AOSP rom, and use the built in tether from that. Its a known problem with older android devices and mobile hotspots.
The Evo Shift gives off the correct one with both AOSP and near stock roms, as its a newer device, so I'm good there, but you'll need to do one of the above fixes. Sorry about that.
Infrastructure vs. ad-hoc
Minor correction (I think). Tablets/mobile devices out of the box support infrastructure network connections. In order to tether you either need to broadcast that mode or modify the wpa_supplicant file on the device to allow it to identify and connect to ad-hoc connections.
I have never heard of ad-poc.
The beta version of wifi tether supports infrastructure on some devices, so some people are able to use it. Best bet is to, like the above poster said, is to load an AOSP rom on the phone and use the built in hotspot. There is an official port of CM7 for the fascinate and I know that has built in infrastructure hotspot.
Thanks for reply. It seems to me if the native or bloatware program that comes with the phone can generate the correct frequency to work on our tablets without the need for any rooting or supplicant files or whatever they are called then why can't a program be written for the market that generates the needed frequencies since it is obvious it is not a hardware issue.
If my opinion sounds dumb due to ignorance on my part, I apologize. However if someone that knows can tell me why it cannot be done I would be grateful.

Not sure, might be because the files neccisary aren't open source, or no one has rewritten them for the facinate. I still think your best bet is AOSP, but you can try getting the apk off the wifi tether Google project page. Could be solved by the newest beta of that, cause it might have been fixed in that new version.

Thank you for the information, WiFi Tether 3.1 beta6 is the one I used and it works perfect on my Acer A100 tablet, no rooting or messing with the tablet involved. I get lousy 3g signal inside my home and I was was still able to watch a movie on Netflix from my Fascinate tether. It also works fine on my laptop. Thank you for all the help, I'm a happy camper.

Force/increase 4G connectivity vs 3G, auto tethering when connected to power

I've got a two part question for some issues I'd like to address while on 4G (some I've called Sprint about, others I know you guys will have the answer since I'm rooted) that I hope to resolve.
My issues with Sprint is that if I'm on 3G and looking at images via websites, pics obviously load slower, but they're always nice and crisp. I notice that when I happen to be on 4G and go look at images, suddenly they load super grainy. I spoke to someone else who is also on Sprint w/ an LTE 4G phone (not a Note II, something else) who experiences the exact same problem. I've called Sprint about it, but I get the usual run around saying they're addressing the issues, fixing towers, etc. When I first started getting 4G in my area about 3 months ago, it was BLAZING fast, connected the second I came off the freeway and stayed on strong. I realize over time that I'm sharing the same signal with others, but damn.
My issues that I'm hoping you guys can assist with is in regards to the phone staying connected to to 4G more via changing thresholds. As I id before, it was awesome. Now it's gotten to the point where I or the phone have to be near a window, or occasionally I can leave it on the top edge of my couch...but if I happen to handle the phone to answer a text messages, it'll often drop back into 3G. The problem is that I use my phone tethered to my laptop for watching TV....Top Gear, Family Guy, etc that I stream. On 4G it's great, but once it drops to 3G it turns into a buffering nightmare and some shows/sites can't handle jumping around for time frames, so lets say if I'm 15 min into a show, go into 3G and come back into 4G, the show never recovers and I've got no choice but to restart the show. I'm just curious if there's a way to change at what point/signal strength that the phone wants to swap back and forth and basically ask it to stay on 4G more often than not when I'm at home where I actually get 4G.
As for tethering, I'm a stock rooted ROM using TrevEMod tethering because the stock tethering app won't stay turned on, I'm assuming due to using the stock ROM. What I'm curious about is a way to have the phone automated in that once I plug it on, the tethering app turns itself on and then back off again once unplugged from a power cord. At one point I'd used some app where it had me enter parameters to do this, but it only worked to turn on the stock tethering app which won't work.
Bottom line is I'd like my phone to stay connected to 4G more often than not, turn on tethering when plugged in and turn it off when not.
as for the tethering, if you are running the stock deodexed rom, there is a mod you can flash to make the native hotspot work then you will be able to use Tasker or however you automate it turning on. if you are running stock odexed you could always flash stock deodexed, if you were intent enough on making it work.
here is the hotspot mod: http://forum.xda-developers.com/showthread.php?t=2232553
I truly don't know if the stock ROM is odexed or deodexed, I just did a simple rooting procedure and nothing more so I could install a tethering app. Maybe I'm just being naive, but coming from my Epic days where I rooted, ROM'd, kernal'd, OC'd, etc days where I removed tons of apps, added others, etc I never was able to get battery stats/calibration to work correctly, which in turn wrecked havoc on that phone...phone would get super laggy, bog and stumble, then I'd reset the phone and I'd go from 20% battery life to 3%, then realize why the phone was freaking out. Now that I've got this Note II, it works great, I've never felt the need to OC or anything (I wouldn't mind removing stock apps but the SDX Stock App Removal Tool doesn't work), so I'm kinda hesitant in flashing any sort of ROM for fear of reliving past experiences...right now the phone simply works great, I'd just like a few simple features. Any input to sway my decision?
i hear ya, i too like a nice stable setup with everything working. your system is probably odexed if al you did was root, but if you have a file explorer app, when you go into /system/app, you will see each .apk also has an associated .odex file. the deodexed rom has the odex part added back into the apk, but otherwise is exactly the same, no tweaks or anything, every bit as stable, and with nothing removed, but it is easier to make mods for a deodexed rom, such as the hotspot mod!
the decision is yours. it is always a bit of work to flash a rom, but this is defintiely a way to keep the stabilty and reliability, and have the hotspot working the way you want it to! the rom is here: http://forum.xda-developers.com/showthread.php?t=2241930, if you choose to go this route. this is exactly my setup, with the hotspot mod, and it runs great.
I'll read the thread, thanks for the link. Any suggestions for something that will enable the tethering app automatically based on being plugged in, and I've had no luck finding anything in regards to people changing thresholds for the 4G connectivity.

no problem. the app Tasker from the market does things like that, i think it costs a few bucks but it's well worth it. and perhaps there are others.
for the 4G thing, i don't see any setting for that. there are other people who know a lot more about network stuff than i do. there might be a dialer code menu where you can set to receive LTE only, but sorry i can't be of more help there. good luck and have fun!

GNEX Without service

First I would like to thank everyone on this forum. Being a Noob to rooting I have learned so much here.
I will be picking up my new Galaxy S5 tomorrow and I want to keep my GNEX for a music player. I believe I will still be able to connect it to wifi and load it with music via USB. Any suggestions as to how I should configure it before I lose service?
I have Vanir ROM running 4.2.2 with DirtyV kernel.
You don't have to do anything. It doesn't matter if you have service on it or not. It will still work on Wi-Fi
Sent from my Nexus 5
yea I have been off of Verizon service for long time now(almost a year)
what I do is Google on airplane mode. then you can just turn on wifi(bluetooth.and wifi are able to be toggled on/off without affecting airplane mode)
I get actually good battery life on this thing that way lmao!
but yea, you can always change your setup later by just using wifi to download your Roms/kernels.
not having service won't affect ability to install roms.
but make sure you do toggle airplane mode on lol. cuz without service(i don't even have sim in anymore) it will be constantly trying to connect to a tower to get a signal, and will horribly drain your battery very fast.
(I've also removed BIP.apk and the stock messaging apk since they always show as running apps and I don't need them anymore I figured just remove them to free that ram up. you will have to remove them every time you flash a Rom though remember, if you decide to go this route as well)
Someone made a flashable zip over at Rootz that disables everything that makes your device a cellular device.

[Q] Rom or app to fix either bluetooth handsfree or disable 4g

Hi All,
I love my captivate, but replaced it with a droid 4 so I could switch off 4g and use hands free. The issue I have is, where I live we have poor cell coverage except for 2g. If the phone has even the faintest sniff of 3g or 4g it connects to that. This results in no calls or few calls getting through, hence needing to turn it off. All the roms I have tried don't seem to allow you to select 2g only (my droid does). Also all the roms I have tried prior to august have Bluetooth issues and have no audio on any of my 3 HF kits. If I use the standard at&t rom, they all work, just stuck with 4g.
I have tried the service menu, but that only works sometimes and I find myself missing a few calls and spending half my time messing with that menu. Any apps I tried, only actually link to the phones menu and don't actually do much more than provide a shortcut.
Please help, as I would prefer to use this over my droid, especially as that has the dreaded earpiece issue. AAARRRRRRRGGGGG

Hi
Have you tried sediROM and if so: are your BT devices working with it?
If that is the case and you want to permanently disable 3G and 4G for the device:
Open dialer
Type in: *#*#2263#*#
Tap menu 3 (GSM bands)
Select 1 (All GSM)
Tap the menu button and press "end" if the menu does not close automatically after that.
Hint: never use the "back" key while in service mode!
That way you will effectively disable or enable 3G and 4G. You can revert by choosing automatic instead of menu 3.
As this is something you do not want to do every day I can recommend the app Llama (2 "L"). With this you could switch on/off 3G based on your location (based on the phone cell , gps e.g. or based on whatever you want). You need to specify a rule within Llama where you define a event and an action. The action can then be to use 3G etc or disable it e.g. when you leave home enable it and disable it when come back.
If sediROM works for your BT devices then you should be fine with either the above permanent solution and/or using Llama.
All the best

Thanks for this. I have flashed phone and will try over the weekend. Thanks for the code hint, I never used to press end, which may be half the problem. I have downloaded Llama too. On initial setup it doesn't seem to be switching to 2g. This could possibly be a error on my part and will continue playing. FYI the code is actually *#*#2263#*#*

Thanks yeah I typed the code with my phone so I missed the last asterisk but you figured it out already.
Llama itself will do nothing until you tell it what to do.
So you need to add a rule within Llama first and then you need to add an action like disable 3G,4G.
Check the doc here: http://kebabapps.blogspot.de/p/llama-handling-guide-instructions.html
In my case the service menu method is working fine nevertheless. Llama would be a fallback only or if you want to have some automatism only (well THEN Llama is a great tool btw).
Have fun
FYI
After a week with the captivate, I was reminded just how much of a pain in the butt all this is. I was happy I had BT, however the 4g just won't go away. I think with the pac rom I could at least get that to stay off, but had no BT.
Llama wouldn't stop 4g. I even had it set to ignore the 4g towers it could see, however it seems to have some kind of AI and knows when you have relaxed that you have it sorted, and would then connect to 4g even though it says "ignore". The service menu does the same and even though you go in and check and it says gsm only it will be on 4g and I would have to enable and save it on, then again off.
Also the wireless in this rom seems to take a long time to wake up when you wake phone.
Close but not worth the hassle.
I have just installed a nokia earpiece in my droid 4, and am able to hear again.

Well sounds bad and thx for giving feedback nevertheless.
The only thing I want to ask is have you tried sediROM or pacman ROM only? Just wanted to have it clear because I do not know which of the above problems occured with pacman and which not or all of them etc..

All the 4g issues were with the original ics rom and also with sediROM, however I could connect to bt. most of the jellybean and kitkat roms were good in controlling 4g, but would not connect to my bt headsets.
Good work on the sediROM though

Removing cellular from phone?

Hello all, I have been using the d2spr for quite some time... without mobile. I have no service on the phone and have no problems using it as an esspresso device like my p5113 tab 2. On my tab two there was a thread about removing the cell from the device, which I will more than likely have to look up again for that device. Is this possible for this phone? Anyone have any experience removing cell from the phone. I have read that searching for signal reduces the battery life, and I have yet to try it on the phone. If anyone can give me any pointers on this would be great. Also if you know which files to delete would save me a crap load of time searching for it.... thanks in advance...

are you basically trying to use it as a galaxy player? (i.e. an android version of an ipod touch?) if so, ive just put mine into airplane mode and turned wifi on manually. It greatly improves battery life as its not using the cell radio.

not exactly I use it as a voip phone and remote control as well as play various games, though there is no service on it, it shows the mobile connection. With the tablet it was a wifi only tab so removing cellular feature from android really increased battery life. Though I was not sure if it would work the same on the d2spr... not quite sure where to start though so thought I would ask, but thanks for the alternative, I am not sure about using airplane and wifi together as I have not tried that before.

gotcha. well, if youre using strictly voip, then the airplane mode and then turning wifi back on separately will work very well. like i said, ive done that with other devices and it substantially increases the battery life. Give it a whirl, what can it hurt?
Just an update with the steps on what I did.. as well as the results. With rooted device I deleted the 3 folders telecom, telephone, and another that starts with a tele that I can not think of. They are located in system/priv-app folder on root of system. (Using root explorer) After that I reboot, and all is working fine with no cellular at all. I have been letting it sit just to see how long the battery lasts on standby. So far I am at 28 and a half hours... I still get notifications and wifi works smooth. In the battery section in settings it currently reads charge remaining 8 days. Anyone with no service like me might want to give it a try... if something does not work all you have to do is re-flash what ever rom you had and that will put the folders back. and install cellular on the phone again... I would say that is the number one battery drain of the phone next to the display...
Day seven of my battery test and So far it appears that without cellular on the d2 you can get up to 10 days of standby charge. I did not use the phone at all for anything but to check status. Also, If you notice the small change in the curve, it is because it downloaded updates. It was connected to the internet the entire time...
