Samsung S2 T989 help with Cell Radio - T-Mobile Samsung Galaxy S II SGH-T989

Hello everyone. I'm new to the forums and not very experienced with Roms/Kernals etc. I recently loaded CWM recovery on my phone, plus I've tried a few roms and kernals now. Love being able to customize my old phone, since it was running 4.1.2 now I have 4.4.4 and I tried 5.1 as well and I had a lot of help from the forums. Thanks for the useful knowledge on this forum. The question I have is, on my new rom I noticed my battery was draining pretty quickly, even on the charger. I checked what would be draining it, and cell standby was at the top. Usually brightness is the main killer. I don't have service at the moment, mainly just using my phone with WIFI for gaming, apps, etc. So I decided to look for ways to disable Cell Radio. I did, I dialed *#*#4636#*#* and gave me the option to turn off the cell radio, however I'm trying to access that same section but when I type in that number I get "Mobile Network Not Available" and can't seem to turn it back on. Any help would be greatly appreciated. I'm not sure if this will help but this is what I'm running: AOKP Hercules KitKat Rom with UBER Kernal so I can overclock to 2ghz. =) I love the speeds and everything is great so far with this setup. Just can't access that section anymore to turn on my cell radio. I'm getting my phone turned back on in a week or so and would really like to use this rom, and don't want to have to do a fresh install since I have downloaded all my apps and games back on it. Thank for any help provided and your time.
P.S I have tried turning on Mobile Network in the settings, but that didn't allow me to access that screen either.

[Q] 3G Won't turn on PLEASE HELP! :(

Okay, here is the status. I have a DINC and I've rooted it, upgraded the hboot to s-off, and upgraded the radios and all that good stuff. I've also ported the phone to cricket with successful results with full 3g, market, wifi, sms, mms, text, etc. So everything was working fine.
Then someone wanted a phone switched like mine so i did it for them no problem. It was working for a day, then it stopped. So I got it, and tried everything in the world to fix it, but 3g wouldn't work, even after reset to stock using ruu, pb31img thing and all that s-on, and everything. Even was verizon prl, radio etc.
But the 3g would not turn on, you go to mobile settings and it would just be greyed out, say "Turning on.." and flash white real real fast and go back to turning on and greyed out. And this is where it sits, no 3g icon nothing.
I've tried the airplane mode and that did not work. Turning off 3g, flashed different radios, different kernels, etc. No avail. Different roms, everything. Even at stock it says this. I've checked the settings PST wise, and even programmed it using ##pst from the phone itself and it commits successfully.
but no 3g turning on. So we sent the phone back because we thought it was a hardware failure.
So my phone was working great, latest radio, latest build of redemptive revolution, latest prl, everything working great on cricket.
I decided hey, i'll just sell you mine, and just get a cheap phone and save some money for a while. So i sold it to her, ported it over to the new number, switched it via cricket told them it was a razr v3c and all that. Next thing you know, same EXACT problem. No 3G will turn on, even after full reflash/flex or whatever to stock. Nothing i can do will turn on the 3g, it just hangs.
What in the world is going on, please someone help me, I feel so sick about this process. I am pretty adept with all of the drivers, adb installs, rooting and apns and all that. I also used the cricket v10 mms.zip flash file and its been working great up until this point.
We got cricket to check the settings on the account and they even did a reset to make sure its not that.
Is there any way I can look at a log file of the 3g radio? to see if its giving errors? Or is there something I can do to diagnose or view what is really going on? Any help no matter how involved or simple would be greatly appreciated. Like I said, I am really sick over this matter and feel so lost
But I love you guys, and you are geniuses and I know someone can help me. Thank you.
ALSO, i've noticed this happens a lot even with new dincs from verizon, so it might just be a hardware failure. I just don't know what to do to check it.
Question ... didn't you make a back up of the stock ROM...?

Some kind of delayed radio issue?

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!

In HDR menu there is a LTE only mode..... beware you wont receive calls or texts so if you have google voice set up then perfect

[Q] Bad battery life?

Hello everybody!
I just got this cellphone and this is what happened so far.
After I got it (brand new), I rooted, unlock it bootloader and install a custom recovery so I can start installing Roms and stuffs.
First thing I remember when I was on stock rom, its the awful battery life, that's actually the reason that made me swap roms.
I started to read every popular thread about LG LS970 roms and the one that caught my attention was Carbon 4.3. It was great, didnt like many of the animations and stuffs that included, but it was smoother and batter life was awesome.
The problem is that at that time, my DATA wasnt configured yet. I tryied many things but I noticed that many of the hidden menu that used to work on STOCK ROM, didnt work at this rom CM based. After some reading I realized that it was because of CM.
So I got back to STOCK and then sent my cellphone so it will get its data configured.
Now my cellphone can use 3G and stuffs, all nice, gps, mms, signal, everything working flawlessly.
My only issue is that now Im back on this horrible battery life. No wakelocks and anything, I learnt about that using other cellphones.
And Im using the same apps that I was using with Carbon rom when I was getting exellent battery life.
So my questions are these:
I dont know how to configure data, and this cost me a few bucks. Is there a way to get back to Carbon ROM without losing this cofiguration? Or will that get wiped off with everything else?
Is there a way to backup/restore this specific data? So I can swap ROMS and get back everything else?
By the way, I live in Dominican Republic, the PRL I use is 30122, I can update PRL easily with the tools provided around here, but couldnt figure out how to edit apn or whatever option was needed to edit to make DATA works. And the guy I paid it for, did it in only 20 mins. Couldnt see how he did, I just noticed that he needed DIAG mode to do it.
I know a few settings like APN (lte.tricom.net), MCC and MCN and stuffs like that but I think there's something else to it.
Also I was wondering if I can connect my cellphone to CDMA Workshop and read it, will that display whatever this guy did to my cellphone? Maybe I can copy everything and then setup myself.
Too many things and I dont know what should I do.
Thanks in advance for any tips/advices/insights.
P.S.: IF there's any kernel, thing, whatever that one can install on stock rom to improve or make it work (batter life) like Carbon rom, then I'll do it. I dont care much about roms, I like some features, but its the battery life the thing I care the most.

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.
The OP is for Jelly Bean, but comment #50 made one for Kit Kat.
I know it's taboo to link over there, but I don't see anything in the forum rules:

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...
