Well after the WOW effect wore off my phone, i am starting to HATE the flaws.
I bought this phone outright for a hefty $600 and hoping i did not waste my money switching over from blackberry.
MY problems
Bluetooth disconnects every 15 minutes, plus sounds like garbage, i did some reading on this and its a common problem yet appears to not be addressed yet? i am using a Jawbone Icon by the way and its dual connected to my work BB
Data(HSPDA) randomly disconnects at least once every 2 days and requires me to pull the battery to get it back going.
Battery drain is beyond crazy, i cant get 5 hours out of the phone with moderate use.
This thing heats up like crazy!!!
I know the last two things are software related, and people say upgrade to KG2, well my phone had 2.3.3 and KG2 and this is what it shipped with, so what should i go to?
Or can i just solve all of these issue by rooting the phone? if so, i will go that route.
Thanks.

if you want to go that way(rooting,FLashing Roms)
Think twice, the SGS2 has a binary counter that counts how many times you flashed unofficial software on the phone,
if you brick it or something happens, screen breaks etc, you might ran into some problems @ samsung if they check the counter
you can reset it yourself by buying a JIG, google it!
I've had no issues with my bluetooth headset (logitech freepluse). i'd guess it doesnt like being dual connected
I've had no issues with losing my data connection (i did on galaxy s though). how strong is your signal before you lose it?
as for the battery drain, make sure you're exiting your apps + all the usual other stuff (turn off sync, wifi, bt, set to autobrightness). 2.3.3 does have the drainage issue for some people. i'm on villainrom 2.3.4 and have no drainage issues
rooting won't help you out.
HSDPA disconnects? if you have H always on that means you are either downloading or uploading something most of the time, H only turns on when there is data being pulled or sent, you should see the 3G icon MOST of the time, if you are streaming music/video then you'll see the H kicking in.
I have a Jawbone Cruiser and have no issues whatsoever I have 2 devices paired to it but only 1 at a time, A2DP works flawless and it even sounds better than the original Galaxy S.

never happened yet on many roms .

Warm but not overhot .

KH3 latest stock firmware on this forum .

Rooting has nothing to do with battery problems all it does if give user a lower level access to the OS .
Hundreds of battery problem posts with tips methods etc but for me the starter has to be ,
better battery stats .

Rooting will not solve these issues, but I can maybe enable you to start solving it.
However, before you start messing with kernels and firmwares I would really try to find out if some of the problems might be hardware related or not. If so, you could use your warranty to get a new one or get it fixed. Once you start messing with custom software you're never sure if they will grant you the warranty or not.

not sure where you get that from? i actually hate apple and take that post as quite an insult, one and only thing i ever owned from them was a ipod way back, and it got stolen 2 mths after i bought it and i never replaced it.
that aside, i came from a Blackberry Curve 8330, although it sucked, it did have good bluetooth connectivity,decent battery life, and did not heat up, keep in mind it was a CDMA phone.
so i know i have some changes to expect with a new network, but it appears lots of these have been fixed by people and i am just trying to understand the software and device, KG2 KY this,etc is all new to me, so i have been reading lots but find it confusing since its so vast.
needless to say it will be kind of disappointing if i cant connect 2 devices to my jawbone icon at the same time and work flawless, as this is huge for me.
Also i NEVER see 3G data show up on my phone, its always the H with up and down arrows, should i see 3G? im up in Canada(Saskatchewan to be exact)
It appears i should update from KG2, yet KIES shows no update, i have not dove into Odin to try that out, maybe i should?
Any help is greatly appreciated.
Thanks.

Rooting doesn't solve anything, just gives you access to hidden files. You need to flash a newer rom(kh3 or kh5) and hope it fixes those issues.
I agree with the above poster, I've been using android since inception and I don't believe in rooting a phone to mask the issues you are having, upgrade the software, there are many roms to choose from, get the device running well before you think about rooting.
People are giving new android users the impression that rooting is the answer for phone issues, it is not.
Rooting is for advanced users who want the extra access to explore the power of android.

I don't understand why everyone seems to be pushing the USB JIG, it's like there are people making and selling them here or something.
@BrokenPixel, H or H+ doesn't drop to 3G as fast, if your Telco doesn't support Fast Dormancy, or you have Fast Dormancy disabled.
I like Blackberries, it is lacking as a end-user smartphone, however for companies, I still like the privacy with point to point encryption. Android does not have that unless you purchase a 3rd party application which means both parties have to have it as well. Again, it really depends on what you are using the phone for. I still recommend using the right tools for the right job.
@Gustopher, calling Blackberries a "second cousin of a minor demon..." is like calling a screwdriver the bane of our existence, or a hammer "the killer of thumbs..."
peachpuff is correct, instead of rooting your phone, perhaps you should try changing the modem to something else instead, try KH3, KG6, KF4, KE4. Perhaps in the mentioned order. It really covers most regions, since we don't know where you are at!

Thank you for actually being informative.
I am in Canada by the way(Saskatchewan) and i am running on the Sasktel network(Bell essentially)
I always thought i had to root in order to install something different then KG2?
i am not sure what my network supports, but i have NEVER seen 3g since the day i bought it.
i have turned off some of the recommended things to save battery life, it seems to be helping, we will see what i get
If your problems are related to your settings, flashing newer firmware (KG5 for example, works fine with me) will only really help if you do a complete wipe/factory reset. See the guides for that.
That would be done best by rooting with CF-root, going into CWM-recovery, doing a backup there, do all "wipes", reboot straight into download mode and flash the fresh firmware via Odin. The guides are all there.
Just make sure to play with some settings like gsm/wcdma in your network settings first.

Have you never heard of BB's? He came from a Curve..basically a glorified pager. He could probably go 3 days on that thing with a single charge. Kind of like going from a Commodore 64 to a high end laptop.
One thing I haven't heard mentioned about rooting is the fact with root you can install Titanium Backup..and with the Pro version..freeze apps (instead of deleting) which allows you to fiddle with perhaps some rogue apps that are draining your battery.
As usual with most Androids..make sure you don't have FB or Twitter syncing crazily (and if you're running multiple tweet or FB programs..be sure they aren't syncing as well). I'm not familiar with Touchwiz..but if they have their own "social networking" apps that you don't use (and you use the actual apps themselves instead) be sure to check those and make sure they arent sync'ing either (and better yet freeze them with TiBu).

stock 2.1 rom 10% battery drain per hour when sleeping
sc 2.9.2 UV 50 kernel (dont remember the full name) 3-5% sleeping in my pocket, BUT 1% drain every 3minutes when the screen is on the LOWEST setting.
Just odined back to stock, and 2.2 was already available to me.....so i OTA upgraded and my battery battery is even worse than that of stock 2.1. 12% percent for sleeping AND crazy battery drain when using the screen... i cant get over 7 hours of using my phone moderately....

Have you checked spare parts to see whats eating your battery?
Here are some things you could have done or do.
-Clear battery stats using terminal emulator
-Use app called juice defender
-Use UV kernel (seems like you did)
-Use Set CPU and bring down max frequency to 800MHz.
-Turn off GPS, Wifi, Bluetooth when not in use.
My suggestion is Odin to DI01 and then get the two OTA's EA28 and ED01 and then just run complete stock, and do not install ANY apps, yes I know who wants to run a phone with 0 added apps, you can update any stock apps, but if you run your phone for a day or 2 with just that setup and your having the same issue then go to verizon and get your phone replaced, also keep track of any settings you change, you want to try and keep your phone stock as much as possible, the only stock setting I personally would change is not have live wallpapers.
If your phone is over a year old, you might want to consider getting a new battery for it. No rechargable batteries stay 100% for over a year.

The phone has not been out a year, so its impossible for him to have it longer then a year.
Good point
Seems like this phone has been out damn near forever. Was trying to help. You have a better idea, or do you just troll these forums looking to bust peoples' balls while offering no actual help of your own?
the fear i have with taking it to Verizon is that. i didn't originally buy the phone. i got it of craigslist....so another question i have is, is there a warranty sticker to show if its ever been taken apart? maybe the previous owner replaced it with a cheap POS screen, that why it eats more battery...

Hmm ... I'm not sure about the replacement screen theory ... that seems like a lot of work for ??? benefit.
I second the advice about going stock and not installing any apps. Also, I don't see that you listed some of the things from Battery Use and Spare Parts that are listed as taking up battery life. There are apps that start things up automatically (e.g. Pandora always starts a service when I connect my bluetooth headset, even though it doesn't do audio and I've never used Pandora over bluetooth) ... sometimes you can change this in the settings, sometimes you have to decide how much you want to live with the app.
Out of curiosity, do you leave WiFi on when not connected to a network? I find that sucks battery pretty bad. I use Locale to turn that off when not at home and only turn it back on if I need it. I also used a widget called Traffic Monitor for a little while to see what was using data.
Honestly, you won't be able to return it to Verizon. My husband bought an Ally off Ebay and found out when we got the phone that something wasn't right, so he went to Verizon store and once they found out where it was bought they didn't even want to help him out.
I would suggest calling Verizon and tell them that the phone you have now doesn't work period. You'll need to emphasize that you need a phone that works. I called Verizon the same night that the store didn't help my hubby out and after an hour with the customer rep, I was able to get a new Ally ordered for him and his upgrade date wasn't until Dec of this year. He got his new phone late Feb/March I believe.
If they say they can't help you, keep telling them that you need a phone, and then ask them if they can see if a supervisor will be able to help you out. I stayed on the call with them, until they had that new phone ordered for him-I didn't give up. If the 1st day you call doesn't pan out, call them the next day as each rep is diff and some are really wanting to help, others couldn't care less.
Hope this helps you out.

I did offer a suggestion, which is the same thing that Verizon would ask you to do, and its the same suggestion even most Carriers should ask you. Same with a lot of computer companies should ask you when you are having issues with your computer.
Reset your machine to standard stock, run all your updates, don't install any apps, and see if it still happens, if your battery is just as bad, then we know its either your phone or battery, either way Verizon will trade it out for you, because honestly what else can it be? The only way Verizon can really say tough luck and deal with it is if the battery life he is saying he gets, is what everyone else gets, which we all know is not true.

I update OTA last week on Verizon to Froyo 2.2. My battery was overheating and draining like crazy from my CPU usage being at a constant 99%..
I found the source of the problem. An app I use for facebook called "FLOW". The CPU usage was cut to 20% when I killed it with "Advanced Task Killer".
I resolved the issue by: Opening Flow.. going to Preferences.. Notification Settings.. Refresh Type.. Checked Periodic Polling (I was using Gmail Experimental previously)
Hope this helps...
Hey guys,
I was planning on getting the SGSII (I just sold my SGS for this, actually) but after lurking around here a bit I'm now a bit weary of going ahead with the purchase.
Between battery drain issues, screen issues, Wi-Fi issues, heat issues, and now approx. 3-4 different versions of the SGSII (which makes me scared of ROM incompatibility between the different models) I guess I just need to ask... is this phone actually worth getting, or will I get shafted by a new, fixed version that will come out in a couple of months?
Your opinion?
No if you cannot differentiate between a few users with problems and the majority with no problem . Dont buy you will only go looking for problems .
My phone and many others have .
One No battery problem
Two No yellow screen problem
Three No other screen issues
Four No WiFi issues
Five No heat issues
Six No problems with rom incompatibility only an idiot will install the wrong rom .
jje
JJEgan Is Right..
I have brought my mobile even after knowing problem.After getting it I have started searching for what is new not for a Problem...
Only problem for me is Screen will become hot while charging but not soooo Much hot just very little other than that Great Mobile..
It will be nice if they release NFC in this not by releasing new model like the rumors saying I9101 etc ..This is One of the Best Mobiles till Now.Many people know about the problem Few People having but still they are buying ..Many shops are out of stock...I will say GET IT
I have to mostly agree with jje, except for 1 point. ALL SGS2s have the discolouration issue, but you have to specifically set up your phone in a particular manner (that no-one actually uses) and go looking for the issue in order to even vaguely comprehend what the "problem" actually is. Seriously, when you do see it you realise that the problem lies in the people whining about it, not the phone.
Unless you're unlucky enough to just get a dud phone, get it and you won't regret it. Best phone I've ever had, and that's after nearly 2 years with a HD2 and every ROM under the sun.
Duly noted. My main concern is not software issues which can and will be sorted out either by Samsung or the Android community, my main concern is with hardware issues (screen, battery, etc) which obviously can not be fixed by the community.

Personally, I don't have any hardware issues.
I get a full day of battery out of my phone, and that's using it as a smartphone (browsing; notifications such as facebook, twitter and news updates; wordfeud etc.) If I turn off all data and use it as a phone and SMS device only then I get about 2.5 days.
As for the screen, I have 0 complaints about it. It's seriously the best screen I've ever seen on a mobile device. I particularly love having mostly black backgrounds. Not only does it increase battery life, it looks bloody lovely!
Please bear in mind that most people only post threads when they have problems. It makes it sound like everyone is complaining, but they're not. If we had a real count of how many users are on this site, compared to how many are having real problems then you'd see it's actually only a small percentage, and you're gonna get that with any piece of tech.
I am not a rich guy but i gambled knowing all the problems i have been reading... So far it is just a great phone... It is a phone that make you gamble
Yet to find a problem. Battery works for a day (if this is a problem for you)...
I keep upgrading whenever a new phone comes out - SGS2 is THE fastest phone I've had with the BEST battery life.
With other phones, HTC Desire, Hero, etc I've had issues that I've had to counter by installing custom ROM's & acting as a guinie pig for the dev's but with this one - I'm on the stock ROM with no updates - it's rock solid and absolutely no issues.
I wouldn't think twice in recommending this phone.
my 2 cents...
to be honest i really love the phone. it has some annoyances but i really do like it. it's blazin' fast, i love android, and even the look and feel of the phone...
now, the only thing is: i only get about half a day of juice (recharge at night and once again in the afternoon and to be honest i just have no clue how people are getting those numbers like 20h+ of moderate use (well i guess it depends on how you dfine moderate use)... i have 0 widgets (4 widgets (stock calenda, stock powermanagement, google search and the beautiful weather thing with clock))...and main thing i do is: whats app, music, some browsing, emails (set to check only once an hour) and of course make calls... but i believe that it has to do with a bug somewhere. i freezed the wifi-sharing thingy and tried everything i've read so far to conserve battery. eventhough i have the screen set to about 10-30% brightness or auto brightness, it not very spurprised, is always around 60% or more and the android os and system use quite a lot...
but all that said, i still love the phone and i'm glad i bought it!
It's definitely a VFM. And frankly I dont have any WiFi problem. Battery it's okay too. And unless you focus at that screen with a digital camera you won't even notice the Yellowish tint. I am frankly very happy with mine.
Regards.

i dont quite understand the ppl who buys android phones and doesnt modify it... i mean the only TRUE difference between iphone and sgs2 is powered by iphone iOS and Android.. which is open source... the other difference doesnt really matter much.. processor ( yea its more powerful but duuh.. there isnt much things to do that really require that much power) or the screen (duuh iphone has abit better screen so what? if u dont look closely u wont even see difference(atleast not me)) so yea if you gona buy sgs2 i RECOMMEND you to do alot of flashing and rooting and play with it around
WITH BACKUP of course... especially the EFS backup
It all depend how you use your phone. Sometimes I it for hours on end and go through 2-3 batteries a day (I have 3 spares).
Today I used it very little. About 7 phone calls, 2 messages and only about half an hour browsing / xda etc. Currently on 85% after 18 hours.
So usage makes a massive difference.

do you think is there a need to change the Kernel version ? or just do the official update and it will be fine ?
Definitely stick to official updates. Regardless of what anyone might tell you, it's a fantastic phone running stock firmware. And if you're not confident about flashing custom roms/kernels (there's a small risk everytime you do it that things might go wrong/you might brick your phone), definitely stick to official firmware.
At the very least until you've done a lot of reading on here and are confident to try different roms/kernels. If things do go wrong, it might take you a few days of research on here to work out how to fix your phone (which means you won't have your phone working for that time), and at worst you'll have to return it to Samsung for repair. Which you'll probably end up paying for as running custom roms/kernels voids your warranty.
So slow and steady, stick with stock for a while and read. Then read some more. And when you're done doing that, read for another couple of months.

Definitely stick to official updates. Regardless of what anyone might tell you, it's a fantastic phone running stock firmware. And if you're not confident about flashing custom roms/kernels (there's a small risk everytime you do it that things might go wrong/you might brick your phone), definitely stick to official firmware.

Sorry but got to disagree, yes its a great phone as stock but with custom ROM and kernels its an amazing phone. The devs here have done some amazing work. BUT (and its a big one) dont do a thing till you've researched your arse off, and you understand all the risks of what your doing.

Latest stocks have been fine, even stock kernels have shown improved battery life. But with a custom rom/kernel combination your setting up a phone the way you like it with many ways of tweaking it.
If you do buy one, update to latest stock, try it out, if your not happy then root and enjoy.
My post was an attempt to persuade the OP to stick to stock should he purchase an SGS2. The last thing we need on here is yet another " Hlap mai fone broked !" post :-/ (and everything that goes with it).

Actually , few phone calls may be total 15 min per day , but i will there will be a fair using for the WIFI may be 4-6 hrs per day , do you think this will effect much the battery performance?

My wifi and GPS are on 100% of the time. I never turn them off. Today, 23 hours since charge and about 2 hours screen time and battery on 69%. But 3g is off (2g only) and no email sync.
Yesterday, heavy usage and went through at least 2 batteries.
BTW, since I got the s2 I've only ever used cf root kernals. Nice and stable for me and the closest thing to stock. Others claim increased performance or have over clocking etc don't interest me. I believe the phone doesn't need them. Also using Checkrom. On the S1, well that was different.

I am trying to understand this phenomena.. I realize this is more of a philosophical topic than a technical topic, but its something I think about ever day when I read the forums and try to help people with stuff.
To start, my good friend, and my wife have rezounds. To be fair, my wife could care less about the ROM she is running, but, I like to keep her updated. My friend and I go back and forth about what rom is better, he likes Rrez rom, I like Cleanrom, but we flash back and forth.
Out of the 3 of us, We have never had any of the problems that I see other people having. Why?
We all (you guys too) have the same phones, we flash the same software, how is it that Joe gets 24 hours of battery life, flawlessly smooth performance, crystal clear reception.. while John gets an overheating battery, stuttering performance, unusable signal and 4 hours of battery life?
I continue to read posts from people complaining that this rom sucks or that rom sucks..
So.. is it the PERSON, the PHONE or...
maybe not all rezounds are the same inside, and maybe some software does not work with some versions of the phone. That seems pretty ridiculous though.
When I flash mine and my wife's phone, i usually "race" them to see who's is fastest (ya.. its stupid i know). But from the first power down, to wiping to flashing the rom. i press the buttons at the exact same time, and both phones complete the process at the exact same time, boot up in the exact same time..
you get the idea.
just to see if there are any differences, I did a clean flash of clean rom 4.1 on both phones, and let them sit with the screens on, full brightness for 1 hour. they BOTH drained to 83%.
These phones were purchased 3 months apart, and one from VZW and the other from Amazon.
my buddy has never had any of these problems either (his wife has a rezound, but she wont let him flash it)
none of us have had problems, why?
I am not trying to discount anyone's problems, obviously if your phone is overheating, its not something you are making up.. but why is it that YOUR phone heats up, yet mine doesn't
This is a real question, and I think it deserves some sort of analysis. A real answer could go a long way to helping people who are having problems others are not.
Case in point, people are complaining that the radios in the new leak suck. They are getting crappy reception and they regret updating.
i LOVE the new radios!!! i get AWESOME reception!!.
Right now im sitting at 17 hours with 30% left and I tethered my laptop at school for 3 hours while doing homework at school.
A few days ago, I let the battery die (didnt charge it overnight) and it charged over 60% in 30 min, it was awesome lol
60% in 30 minutes? on the new ICS firmware? it took me 1 hour and 20 minutes to go up from 14% to 70% today...

trust me, I was just as surprised as you, I was sitting in lecture and it shut off on me. I went to study and plugged it in with the HTC charger and the supplied cable (i love that cable) while I read over some material, 30 min later I unplugged it and it was at 62%, I almost fell over lol
im on 4.1 with stock kernel. I flash my phone so much that I dont have **** installed on it (battery saver wise or whatever). It just a normal phone. I dont OC it, I dont run apps that close programs..just stock build
I've wondered the same thing. I'm somewhere in the middle here. I have some heat problems (can't charge and use a lot of mobile network, heavy games push me to 120-ish), my battery life kinda sucks (it's great, as long as I don't use it... but I get like 2 hrs screen on time). Overall though, it's not a terrible situation, and I still dig the phone.
But stories of 24 hour battery life and never seeing temps above 90 sound like tall tales to me.
I think some of it is that we all have our own interpretation of "moderate" use. I'd imagine some people think two hours of screen time is moderate use (a few facebook checks, some phone calls, and some email over the course of a day). To me it's extremely light... I'm at an hour+ by 10AM most days, 2 by the end of work, then I run with gps, play a game or two in the evening, and you get the idea.
I can't speak for those who have radio/ reception problems... but I've become pretty convinced that the other two main "issues" are mostly due to perception.
I think some of this may be location... if you are in an area where reception is spotty, your phone works harder to gain a connection, gets hotter doing it and uses more battery power.
I went from last Thursday to Monday morning with zero WiFi and the phone was using more power than my normal use, but the connection was solid, speeds were solid as well. I normally use WiFi most of the day because if I am at home or at work, I have a good solid WiFi signal and the phone uses less power (for me at least). My test over the weekend was a good test for me showing that while 4G was solid, if I have WiFi available I save battery power using it.
In general, I have rarely had issues with any phone that I use. Never had to replace one or return it for defects or any other reason. I am good to my equipment though, my Dinc still looks brand new and I got it pre-launch.
It's about 20% phone problems and 80% problems with the people. A good majority of people who flash and then complain are those who don't know what the heck they're doing. In the case of the new firmware, many didn't follow the directions to a T. They got a bad flash or a bad download. Then there are those who flash a new ROM and don't take the time to read everything before doing so. These are the 80% that are essentially complete morons. They do idiotic things that just can't be explained. These are the types of people who should either not be flashing ROMs or who should be using iPhones. In my opinion, if you don't read everything and then complain about something not working correctly, it's your fault.
That being said, there are phones that just suck straight from the factory. Some people who really know what they're doing have these phones and get bad results when running the new firmware and different ROMs. There are plenty of these people on here that have these issues. I feel bad for these people. I certainly don't feel bad for the other 80% who go into a thread and complain that the ROM sucks or something when it's completely their fault.
EDIT: And yes, much of the battery drain and temp problems can be blamed on location for those who have phones that just can't seem to grab a 4g signal for too long. I live in an area where my 4g is solid 99% of the time, so I have no issues. I was in an area about 2 hours south of where I live the other day, though, that had crap 4g signal. My phone definitely drained pretty quickly that day and did get a bit hot.
These are all good points. and actually I never considered location before,
And i thin you are right on with the perception. There has to be a way to standardize some of the stuff to rule out perception. So when people say "man i get crappy battery" We can say "well did you run the (insert standardized battery test) test? what was the result?"
say the test was something like leaving the screen on for 2 hours, starting with a full charge and in airplane mode to rule out reception. Theoretically, all phones with the same ROM and kernel should drain the same amount ..
It is also common for people to see a new mod/rom etc.. and rush to try it out without doing any prep for how they will recover if it doesn't work, how to go back, ramifications of the changes they make... checking first to see if others had problems with it first... etc.

lol, Rom devs should put in a system where new people are required to read the entire "read me" file along with flash instructions, and then answer a 20 question test and score at least 90% on it. Then, and ONLY then do they get the DL link After 10 or so times of doing this, the requirement would be lifted.
this idea makes me laugh..

Hahaha that's actually a really good idea lol I would change it to 95% or higher, though.
i know for a fact i'm not blaming it on the rom, or not reading right, or not flashing the firmware right.
i did everything right, and i'm 150% positive of that. thing is, when a rom runs great for the first 4 days or so, then out of nowehre i'm going from 18 hours of battery to 5 hours of battery, clearly there's an issue SOMEWHERE.
i'd love to blame it on verizon trying to push 4g here, but i run on wifi most of the time, so i don't think that's it.

posts usually start like this
"I tried searching but didnt find the answer...."
and then they ask how to flash the rom, or something else that has been covered 1000 times (you have to UPGRADE TO NEW LEAK FIRST)
yeah man, i really hope it's not! everything went smoothly...well, almost smoothly, i was one of the few where the phone froze on the white HTC screeen, and i did a batt pull, and when it rebooted, it began the second step of installation..but i have yet to have any force closes or anything. maybe i'm subconsciously using my phone more? i really don't think so. screen on time should pretty much help judge that, and it's not showing anything out of the ordinary...and better battery stats isn't showing any crazy up time..my awake time is like 39%..i mean, maybe the 4g issue is it? idk..like i said, i run wifi often, so that means mobile networks OFF...
then again, i'm running just 3g tonight ot see if 4g comes on again, and 3g keeps turning off, and switching to 1x..like, constantly...so they MUST still be doing something down here..

I got stuck also. Scared the hell out of me. But mine seems to have gone through the RUU perfectly and I've been getting insane battery life lately. Like at least a day every cycle on a stock 3.8v. It really could be a case of bad timing with the new firmware and Vzw updating 4g in your area that could be killing your battery. I hope you figure it out soon, though. That would be driving me insane.
you're running the RUU? i'm running joel's Bamf. works pretty well; i like ICS better, in general

Sorry, I meant I ran the leaked RUU and firmware and that's where I got stuck for a minute. But I'm on BAMF right now. I always run the latest BAMF.
Phone - Galaxy s2 i777, about 18 months old, running the factory ICS update
Ok, so I was initially having problems with my phone rapidly losing charge - Shutting down at 70% booting up at 40%, I assumed it was shutting down because it was over heating due to a large amount of power being discharged at once. I lived with that for a while, I assumed a new battery might fix it.
Next, before I got a new battery, my power button stopped working, so the only way I could unlock my screen was to get a message, or plug the phone in.
Now, I've installed ShoStock3 v2.5.1, (started out installing a kernel by Jeboo) then switched to Siyah v7.9
The power button issue came back after a short amount of time with the jeboo kernel, but seems to be fixed with the Siyah kernel (I'm not sure if that is just a timing/coincidence thing or not, but I thought it was worth mentioning)
My real issue now is that I have almost no service, I get anywhere from a "no service available triangle" to a 3G or H+ symbol with no bars shown. Every now and then I get a few bars, receive a few messages, and then the bars go away.
I assumed it was the modem since ShoStock3 says it flashed the modem during the installation dialog, I've tried using:
UCKJ4
UCLE5
UCLK3
and UCPLC5
so far, and nothing has worked. Maybe I'm just a noob and using the wrong modems, maybe it's a hardware issue, no idea.... so please help me out, I've been searching the forums for a couple of days to fix my problems, you guys have been great so far.
Also, I'm from around Baltimore Maryland in the US if that helps narrow down what modem I should be using.

Modem won't affect service. Are you sure you aren't in a dead zone? Also the battery thing is normal for our phone if it reboots
Nope, not in a dead zone. The issue just started recently, before I had plenty of service. WiFi works, but both my cell service and my GPS won't, which I thought indicated modem... any other ideas?
Thanks for the reply.

Try going back to stock gb?
Okay, so I'm still on shotock3 with the siyah kernel and the I777UCLE5 modem. I changed my APN settings around to match what I found in this thread:
Http://forum.xda-developers.com/showthread.php?t=2021401
It seems better than it was, but still not working properly. The connection comes and goes, when I get a connection speed test is showing about:
120ms ping
3.8Mbps DL
.4Mbps UL
But most of the time speed test won't even connect to a server.
Anyone have any idea what could be causing my phone to have service sporadically?
Maybe they're doing service in your area or having issues. Also meteorological events like solar flares and things can wreak havoc on service. May not be you.

Is my problem just some ridiculously easy thing that everyone knows so no one wants to help a noob? Or am I just getting bs answers because you don't it? "Modems don't effect signal", "are you in a deadzone?", "solar flares have been known to mess things up"
Can I give more information to help out? I'm not a noob to forums, I'm a noob to this forum, I've searched, I've read stickies, I just can't find a solution (my searching is probably not as fruitful as an experienced user's)
I haven't tried going back to gb yet, but I will tonight after work if you think that could help. I ran ics for months with no problems though, so I don't feel like that caused the problem (granted I'm on jb now, but still).
I know you guys are the ones helping me, so complaining about bs answers isn't all that smart. But answers about solar flares make it harder for other noobs to search for this problem and avoid posting.
...Did u think I was being a smartass? If so, u may want to learn more about the world we live in. Because everything I said as well as all the answers you got were completely legitimate and none were BS as you called it.

Don't come to these forums looking for help. Then blast the people who are giving you sound advice. I have been running the same rom you posted since release. I too flashed UCLE5 because I haven't had as much luck with the standard modem Sho uses, and have great signal since flashing UCLE5. No issues here. Could be any of the number of suggestions mentioned in this thread. I would suggest you take some of the above advice, and maybe thank some of the people who gave it to you rather than being an ingrate. When you flash a modem run it for a day or so and let it settle in as well. Don't just flash it, run a speed test, and then flash another. Sometimes after flashing it seems it takes my radio's a day or so to even out.

The "service in your area" part is EXTREMELY legit; used to happen to me all the time.
Not entirely wise to criticize those trying to help you.
My problem has been going on for 3 days, both at work and at home, roughly 50 miles apart, and no one else around me has been having any problems. Also, no GPS signal... therefore I think I can eliminate both service in the area, and astrological events.
I think step one before anyone goes to the internet to ask for help from strangers, is to find someone close by and say "hey, do you have at&t? Are you having any phone problems?"

I honestly assumed he was just being a smart ass, I know I'm the one asking for help here so I'm not trying to be an ingrate. The service thing is a fairly easy thing to check though, i can't imagine someone wouldn't check that first. The solar flare thing is funny.... but not really helpful...
I didn't realize that I needed to let the modem settle in first... being a noob, I didn't even consider that. it's been about a day, with noticable improvement from when I first flashed it, but still not what I would call functionable.
the only two suggestions on the problem in this thread were trouble with the service in the area, and solar flares, I was only trying to rule those out. The suggestion on a solution, was reinstall gb. I was initially planning on doing that after work today, but now I think I'll wait for the modem to settle in longer.
Any other suggestions on what the problem could be would be helpful. Again, I wasn't trying to be ungrateful, just trying to point out that i didn't think those were legitimate suggestions on my problem. My apologies... I have used xda posts for past problems, and am immensly grateful to have a community like this around. I have been trying to obey the "suggestions for noobs" "search before you post" etc...
Are you under warranty? You may be having a hardware failure since it is affecting your radio signal and gps.
Sent from my SGH-I777 using xda premium
No warranty, the phone is 18 months old, I haven't ruled out hardware failure. That was actually my initial guess, but then a new modem and time seem to help slightly...
I was under the impression that the gps antenna and the cellular antenna (and the speaker) were on the same piece of hardware, and both the GPS and the radio were controlled by the modem. That could be way off though.
Not sure what modem you are useing now, but you did say with ics you were fine and I am pretty sure the UCLE5 modem was the one that came with my 4.0.3 update. It seems to work best for me. If that is the one you are currently running let it settle a bit. I have also seen some people in other phone forums here complaining of throttling of late as well. Just a thought.
Throttling would be slow speeds though right? Not the lack of ability to even send a text.
When I do have service, my DL speeds have been around 4Mbps, which I think is decent.
My problem is more like the signal fading in and out, it almost seems like when I have a good signal then try to use anything that requires data, the signal disappears, would that be throttling?
No.
His issue sounds like a hardware failure. My I777 recently started having the same problem; I tried everything from flashing different modems, returning to GB, even disassembled the phone and swapped the part that controls the signal reception from my wife's to test.. everything I tried was a no go. I eventually figured out after some intense searching that the motherboard was failing, so I decided to just get another phone. Right now my three year old son uses it to play games and stuff. I'm not saying that yours is the exact same issue, but as Red_81 suggested it may be a general hardware failure. What you need to figure out is whether this is exactly so and what is the root cause, then determine if you want to replace the failed part or just get another device. They're pretty cheap on Ebay. Hope some of this helps point you to find a solution.
