Downgrade from LG8 to LG2? - Sprint Samsung Galaxy S III

I updated to LG8 a few days ago, and ever since, I have been experiencing terrible battery life.
Is there any setting that I can change to get the radio version to what it was before the LG8 update? Or is there anyway that I can downgrade from LG8 to LG2? I am unrooted and completely stock.
Thanks.

That can be done.
First try fixing the problem. It is not universal to all LG8 user.
I don't know the root cause and I never experienced the battery problem, but I do see some users report your symptoms. Some of those report that clearing the cache memory cures the issue somehow.
If that doesn't work, use Better Battery Stats to try isolating the issue.

If that doesn't work, I would assume there is an ODIN stock image that could put you back to LG2.

Don't resort to flashing radios you can really screw up your 4g.....Did you try factory reseting your phone but back everything up first and see if that works if not try flashing a stock rom or a ruu.
Update Profile/PRL. If that doesn't work, flash a stock RUU and Update Profile/PRL. If that doesn't work do a ##786# reset. That should get you up and running.
If you still have problems post back and I will point you in the right direction to fixing your data profiles.
I also have the same problem using myn rls4, but have net 4.2.1 cfs HAVS more kernal. Out of nowhere the data will just cut out and stop working. I will try some of the suggestions in the thread.
Did any of out suggestions work for you?

well i went back to CM 6.1(newest build) and about 45 minutes ago it happened again while i was at the bar. guess imma go to a non rooted RUU to see what happens
not to be "that" guy but one bump for a hopefully permanent fix.
As much as half of us have a rom flashing addiction. I cannot do this every day lol.

If that doesn't work. Call sprint and tell them your phone is having really slow data and it's going in and out tell them it happened after updating your phone through system update then they will say it's due to software update and they will send you a replacement next day.That is my suggestion because you don't want to screw something up that might be noticeable trying to fix your current evo just get a new one and start over with everything updated. I hope I was helpful
I did this, using the debug menu once. I reset all data and then it wouldn't update my profile so I couldn't access my 3G and the web data was gone. I tried to update my profile/prl and it wouldn't, kept timing out.
Every time I would reboot the handset it would try to update automatically but fail. It turns out the rooted rom I was on, (Fresh EVO) was interfering with the update. I flashed the stock RUU...then the phone attempted the same update profile, and afterwards it was back to normal.
So try going back to a stock rom, and then if it doesn't automatically try to update your profile, go to your settings and do so manually, should do the trick.
Basically do what APH noted in his post...sorry must have skipped your posting.
This same thing happened to me on the Hero. I RUU'd back to Sprint's crap and then called them. They walked me through some things and then told me to take it in. The repair guy did the same thing I did (RUU and then data fix) and it started working. So, if all else fails, RUU and bring it back to the store.
thank goodness i have a long weekend. Guess if the new PRL update doesnt fix this then ill head over.

4G won't connect after flashing ROM

First Android phone, so I still getting up to speed so hoping someone could answer a couple quick questions. I'll start with the questions and then give the history.
1) How do you determine what ROM you have installed?
2) Any ideas why 4G won't connect? Is there any way to troubleshoot this?
3) Is there anyway to tether on 4G?
So I dove right in after purchasing this phone and flashed a ROM (Zedomax) so I could tether. After installing this ROM my battery life went down the drain and it wouldn't hold a charge for more than 6 hours.
So then I flashed the EG30 stock kernel and my battery life returned to normal. Still wanting to tether I tried another ROM (don't remember which one). This ROM had the same battery issues so I once again flashed the stock kernel back to my phone.
So now my battery life is great, but 4g won't connect (i'm in NYC) for a few days now. I've tried pulling battery, want what not to no success.
I believe I am running the stock kernel, but to my surprise I still have root access. No triangle on the home screen and ODIN says I'm using the Samsung Official binary.
Just to clarify, you are flashing kernels, not ROMs. Zedomax is a kernel, EG30 is a kernel, etc. You can find your current kernel version under Settings > About phone > Kernel version.
Also as an FYI, I wouldn't be going all willy nilly flashing kernels that you can't remember the name of. I'd have to imagine that's a good way to possibly brick your phone or have problems like you are with 4G.
I'm no expert on this stuff by any means but I'd probably recommend flashing Bubby's stock kernel or chris41g's version of it that is packaged up with CWM. These will get you back to the stock kernel (assuming you're not there already) and probably get your 4G working. Otherwise you probably need to update your PRL or something along those lines. Someone who actually knows more about this stuff (i.e. not me) may have a better suggestion for you.
Thanks.
Kernel version is 2.6.35.7-SPH-D710.EG30-CL435734
Is that stock?

Yep! 10 char
Cool.
So flashing to chris41g's or Bubby's kernels probably won't help me. I'll go searching to figure out how to update my PRL but if anyone has any other ideas I'd be grateful.
Also does anyone know if it is possible to tether over 4G? I was never able to connect unless I turned off 4g before tethering.
It is working again. I started over and flashed Stock-EG30.tar and all is good now.
Out of curiosity did you update your system profile after you flashed? I think it's recommended to do that every time you flash a new kernel.
Settings > About phone > System updates then choose update profile.
Edit - Ahh cool looks like you got it worked out. Cheers!
Nope, I never updated my system profile. That could of been a fix....
Interestingly enough, I was retracing my steps after going stock, after each step I checked 4G connectivity. I lost 4G after enabling AdAway. So I disabled (each change requires a reboot) and got 4G back after the boot. I enabled it again hoping to be able to isolate the issue but after that next reboot I got 4G access with AdAway enabled.
Can't say it is AdAway, but after toggling it, I got 4G back.

[Q] Total Signal Loss, Again

My wife and i got our GNex phones at the same time in April through the Amazon wireless store. Both of our phones had to be repalced by amazon within the 30 day window for 4g/3g/1x signal drop issue. 4g radio would just totally crap out, then would wipe out the 3g and then i would have a complete signal loss. Everything was fine after we got the replacement phones. My wifes phone is totally stock and has had zero issues. Mine is rooted running AOKP toro IMM761, Android 4.04. 4 days ago it started having the rampant 4g signal crash issue again. I've turned off the 4g radio for now, but according to NoSignalAlert, with just the 3g radio on i've had complete signal loss 7 times today. I'm in the same area as usual, my house and my office where i normally have 2+ bars of 4g. I'm thinking the radio has gone bad in this phone, like it did in both of our previous GNex phones, it just took this one 6 months to die. Now i have to deal with Verizon Wireless to get a replacement. They are wanting to make sure i'm on the most current build, baseband etc. Here are my questions.
1 - What is the most current stock ROM, radio, build etc. that i an put back on my phone to both a)make sure that a rooted app/baseband etc. is not all of a sudden causing this issue and b) i can talk to VZW and they won't know i've rooted the phone.
2 - Once i return the phone to a stock ROM, i assume that I will have to do an OTA to satisfy the VZW tech. If the phone does not need to be replaced, i.e. the OTA fixes it, will i still be able to root back to an AOKP ROM?
3 - Is there some other update i should try before going the "unrooted" route and trying to talk with Verizon?
Thanks for your help.

Here are the VZW radios for the Gnex. Personally I would try flashing the new one [4.1.1 (JRO03O)] with a JB ROM. I was on AOKP for pretty much the entire life of my Gnex, 8 months, and never tried CM10. Flashed CM and besides the Nav bar, which I like better in AOKP, I have seen substantial improvements in performance, stability, and even better battery life. If you are determined to stay with AOKP I would still update to the JB version and try those "new" radios.
I started having the same problem a couple days ago when flashing a ROM went bad so I had to restore to an old (4+ mo. old) backup. From there I flashed factoryrom jb and then flashed the new radios today Cuz I just noticed the lack of signal. Still no bars anywhere. Any other thoughts? Do you think flashing a CM would fix it? If so, why?

What is selected in settings-more-mobile network-network mode?
data enabled is checked, and network mode is LTE/CDMA
I was gonna try to find a fix today and if i can't find one, flash to complete stock, reroot/mod etc.

Well, your settings are good to go. Did you check the md5 sum of the radio file after you downloaded it? If you have root explorer hold down on the .zip file and choose properties to check the sum and make sure it matches.
hahaha i guess that's what I get for trying to download a radio on crappy mall WiFi... the MD5 was bad :-/ works good now! thanks!

Hmm, it did this "need to restart SIM to work properly" crap, restarted and stopped working. Any thoughts? I'm installing franco kernel to see if that helps
Welp I ended up just flashing the factory image hahaha, will reinstall ROM and see how it goes. Everything seems to be working fine right now though
Glad it was something simple like that to get you back up and running.:good::highfive:

I d/l the 4.1.1 radio and flashed it in clockwork, and though the flash said it completed successfully, i don't see a way to check the radio version. I don't see 4.1.1 JR03O listed anywhere in the About Phone information...Where should i be looking?
Further, my prboblem seems to have further degaded ...With the 4g radio on, i get random total shut down of the phone, as opposed to simple radio crashes. Just goes to off with black screen. I'm up to try anything. I assume i can easily locate one of these JB ROM's in the dev section?

The baseband i think. Mine is I515.09 V.FF02 / I515.FG02.
I'm not all that knowledgable about the radios I just know my reception/data was poor on JB ROM with ICS radios. When I flashed the JB radio, my issues were fixed. I believe the ROM and radio versions should match, so if you flash JB radio I would flash JB ROM. All the info should be in the thread that is linked.

I am such an idiot, this whole time you've been talking about JB ROMs i assumed you meant some particular brand of ROM, like AOKP or Myn etc... It didn't dawn on me until i saw JB next to ICS that you meant Jelly Bean ROM.
Ok i'm running an AOKP Jelly Bean ROM with Android 4.1.2
baseband is the same as yours
Build is aokp_toro-userdebug 4.1.2 JZo54K
The radio problem seems to be resolved. Thanks for the point in the right direction!
oops, accidentally wiped my sd card when i was restoring back to factory... TOTAL back to factory hahaha.... which isn't so bad i guess... after a year it's about time I guess
I seem to lose signal when leaving wifi though, have to either airplane mode or reboot. Because I had my phone so long, I don't know if there was connection or dust issues, so I did the classic NES/SNES/Sega Gen trick, took the sim card out, blew in there and all that. Seems to still be going ok.
Fyi.. i a simple restart doesnt disconnect u from the towers.. u need to turn off, pull battery, pull sim, and wait for 10 20 sec. That will disconnect u fully..

Galaxy S3 Shutdown

Hey guys,
starting last night my Galaxy S3 began to freeze and then randomly shut off. I then had to press the power/home button for a while for it to turn on (around 20-40secs). At first I thought it might be a battery issue, but I used another S3 battery and the issue persisted. I bought the phone in June, and it is currently unrooted but running a leaked Bell Jelly Bean rom which I installed a while ago....
Not sure what the issue could be, and I was wondering if anyone else was experiencing the same issues or if anyone had a fix?

What ROM are you running ?
Same here, started last night. I'm not running a ROM just rooted and a few apps removed. In the process of reverting to unrooted stock to see if that helps.

It might need a factory reset
EDIT: Ahhh I just noticed you must be on the international version. June didn't ring a bell until I remembered we didn't get carrier models until July
Might want to head over there

i agree on the reset. as a matter of fact, i'd suggest a full wipe, flash the appropriate stock firmware in odin and full wipe again. this tends to solve the biggest issues when users update/change android operating systems.

Do y'all have the i747 or the i9300 international version ? 4.1.2 was never released for north America phones and you quoted a UK version of the OS
Don't flash anything on this site unless you have a i747 or i747m

Having Wifi problems

Hey guys, I'm just wondering if anyone else has had problems with their wifi not wanting to turn on,
I've switched roms, I've went back to factory. Everything i can think of. So If anyone has some experience with this,
Or ANY clue whats wrong, Please let me know.
Thanks!
Why don't you tell us exactly what did you did when it stopped working
Nothing really, Just normal use on Stock when poof it didnt work anymore. I rooted and used custom kernels/roms to
try and get it back working. But it hasnt worked yet. I think It may have been after an OTA update from ATT. But that shouldnt linger after a full wipe, would it?
reboot your modem and router at home..
That Didnt work, It doesnt work on any wifi network. The phones wifi will not enable.
what does your baseband say?
Baseband is I317UCAMC3
ok, that is ok...what rom and kernel are you on?
Rootbox's 4.2.2 Rom with its default kernel. But this issue started happening on Stock, non rooted. And has persisted all the way through 3 different roms so far.
Ok, this is supposed to be only for the gt-n7100 version but it sounds real familiar and if it's a bug in jelly bean it could be your problem. Either way it shouldn't hurt to try.

Since we do not have a stock UCAMA3 Build to flash via odin, what build are you flashing to return the stock build ??
Are you downgrading and taking the update ??
We need more information..... as a step is missing I believe. ..g
