sorry about this thread but i am getting a bit confused with flashing roms on my s2. my handset is not even 3 weeks old and i am already sending it back due to the drainage of the battery. what i mean by that is that i must of flashed the handset like over 40 times till i found the rom that would not drain my battery so fast. i tried cognition, villainrom, batista and everything and my battery was going like hell. within like ten minutes of just having wifi on and just doing my normal browsing my battery from fully charged went down to 85% and that is with data package off and hardly any widgets on. and all the time my display was the highest thing in my battery stats taking the most usage of my battery.
anyway i am sending the handset back and hopefully they will send me a new one. what i need to know is that can install any rom on my new handset once i receive it or do i need to find one which matches my firmware. ie say im ke7 do i need to find a rom with baseband ke7 or can i just flash it anyway say with kg6 baseband?]
sorry if my questions sound stupid i just do not want to flash for the sake of it if its going to harm my handset again.
cheers
Multiple flashing is a bad move to solve battery drain .
You can flash any rom .
Baseband is the modem not the firmware .
Why mess up the phone the minuet you get it in your hands again .Far better to read and learn how and what.
better battery stats .

thanks for replying back JJ and yeah i kinda realized now that it was a bad move flashing alot but can you help me with this then. why is it when i flashed a custom rom my display was sky high in battery usage display and now that im back on stock its normal and i mean 30% and lower?
i had an iphone 4 and was into my jailbreaking and etc but i feel like rooting and flashing is a whole lot more confusing or shall i say pro wise.
[QUOTE=JJEgan
Baseband is the modem not the firmware .
but does the baseband matter in what rom to flash though? say i have ke7 baseband do i need to find a custom rom with ke7 or can i upgrade it to the baseband the rom comes with?

No you can use any modem and even flash it on its own .
KG3 7 KG6 probably the best current modems .
A flash requires two further processes . One charge battery fully . Two zero battery stats then the phone must be used for a week or so to get an accurate indication of battery life .
I believe the key to good battery life starts with a good overnight battery drain when the phones is sleeping . If the drain is high here its going to be even higher in use . Aim for 2% drain over twelve hours sleep if its about 20% then stuff is connecting or waking the phone up .

i have already sent the handset bk today so hopefully they will send me the new one by the end of the week. problem is when i put the stock rom back in and upgraded the firmware through kies officially everything on my battery stats looked normal. so i really do not what the problem was with the handset when i flashed a custom rom and made the battery drain quickly? and also worried that seeing that they might send me the handset back and then i would not be able to flash a custom rom? whats your advice please JJ

Thanks a lot for helping a newbie mate.
i am gonna do exactly as you said.
btw iguess its true what the guy told me that on most of froyo roms , there is a major glitch that if someone is calling you then he ll hear the ring but there will be no call at ur end . ?
as with eb01 i am facing this.
I like
There is a phantom call issue but that's only on the AOSP ROMS. Any Touchwiz based ROMS like Community ROM aka Ultimate Kangbang and Evil Fascination will NOT have that issue.

If you are already on SC 2.9.2. It's likely to be safe just to wipe Cache/Dalvik to install Com Rom.

the first one is superclean i suppose, it works good , but the battery drain is a real pain in it , i mean it drains like 1 point in 5 min LOL.
i believe the first one can be simply installed with odin in one go , withouit doing anything else .

Battery Drain can be solved by ReCalibrating(Charge phone 100% > Turn off, Charge 100% > Turn on, Charge 100% > Recovery > Advanced > Wipe Bstats) or tryin to erase couple of apps that might causing the Battery Drain.

Too subjective to say - depends on your usage and the kernel.
Custom kernels can be tweaked more than stock kernels - some tweak for performance, some for battery.
Never used hyperdroid, so I can't compare. On my ROM (see sig) I have Redpill kernel. I compared it once against my stock backup, and got about 75 minutes more battery. But it was hardly a scientific test.
Just flash a couple of stock ROMs and find out how battery life is for your setup/usage.
Generally speaking the latest stock is best .
Generally speaking custom roms are better battery life
Generally speaking battery life is a factor of user and the apps and settings on the phone coupled with usage .
Better battery stats and wakelocks are the starting point .

i dont have any problem with region because that thing doesnt matters in my country i just want a good simple and less buggy firmware just tell me name of it and also give me reference from samfirmware site
Then go to Samfirmware & choose whatever firmware for whatever region/carrier you want. You can't search yourself why exactly ? (I suspect laziness has a bit to do with it).
ICS Rom
My current ROM is from westcrip :
http://forum.xda-developers.com/showthread.php?t=1436854
Resurrection Remix ics v9.6 exclusive XXLPH 4.0.3 Full-Wipe
If you're looking for something stable, fast, no FCs(if you install it correctly ), no orange triangle when you boot your phone(this is not the most relevant because there is an app to remove it, but it was a nice surprise the first time I booted the phone), I would recommend this one.
Hope this helps.
Well i got a second hand S2 and i would like to "clean" it and install a better rom and a better firmware as the battery life is very short about 17 hours.
My problem is idk which one is better for my device. Should i stay on Giner or pass to ICS?

ROM - XWLA4_CheckromRevo_HD_V6 (Most votes on a pool thread)
KERNEL - DarkKnight_2.5.2 (found it on checkrom page, i could not find a pool for kernels.. )
any advices for a good kernel?
battery life still poor
Few days ago i managed to get a 25% (as can be seen on Old Results attachment) display usage but suddenly has raised to over 45% and no matters what... it wont go below that level.
You can have a try of Siyah's Kernel.

well if you are getting 45% for display you must be using your phone or your display is turned on alot.. download betterbatterystats_xda_edition here on XDA .. its free (just search) and check your kernel Wake_Locks
also CPU spy from market to check is your phone going into deep sleep

FWIW, 17 hours is not bad, depending on what you're doing.
If you are actively using the phone with a screen on time of at least a few hours, with full sync going, that's actually pretty good.
If this is pure stand-by time (you're not touching the phone at all) it's on the mediocre side, but still not terrible if you have full sync going.
I can get 24+ hours if I hardly use the phone at all, or about 6-7 hours if I'm constantly using it for web surfing, facebooking, XDA, games, GPS, etc.
Battery life is completely subjective to how you use the phone.
Hey guys,
I'm here because I'm new to flashing, rooting and whatever comes within this territory. I own a Samsung Galaxy S2 which was bought from a retail store in New Zealand. It's not an imported phone however Vodafone is its "Carrier" of choice.
What I want to do, is flash the device with this ROM because I am having battery drain issues with the Stock ICS 4.0.3 firmware. I have tried everything, removing apps, wiped cache partition a few times, but when Wifi is on 24/7 it drains from 100% to 0% in literally 8-9 hours flat. That's with me doing absolutely nothing with the phone.
I installed BetterBatteryStats and Battery Monitor Widget. The latter app shows my phone discharging -8.0% while Wifi is on and -0.2% when it's off. BetterBatteryStats doesn't indicate anything that is obvious.
So, I'm hoping a ROM like Lighnting may help. Plus, I love it's theme, look and feel.
Down to my real questions.
If I have any issues during flashing of the ROM, can I return the phone back to its stock firmware?
What is the procedure to do so?
Can anything go wrong?
Thank you
STEALA
Here's couple screenshots of my battery usage. Yesterday there was an update so I updated. Wiped cache and factory data reset. All I installed was AirDroid and setup Gmail.
The drain is quite excessive.
you can revert by flashing a stock rom on odin

Hey,
I'm running a rooted stock ICS on my SGS3 right now.
It's I9300XXBLG8.
I wanted to know few things before I flash the new JB for international version: I9300XXDLJ4
1. Does it safe to flash the new JB with odin over my rooted ICS? Will it make some conflicts or problems?
2. Do you recommend flashing?
Right now I have a really good battery life - when I go to sleep with 100% I leave 3g on and after around 7 hours I also have 100%, and the battery is really good. I'm afraid that JB will have bad battery life because it's important to me. What can you say from your experience with JB?
Thanks in advance,
Elad
1. just flash using odin (pc or mobile)
2. don't really get your meaning, just flash only

1. It is fairly safe yes but if you flash a stock rom with odin i'm pretty sure you'll lose root. If you have CWM you should download a stock rooted rom and flash it through through CWM.
2. I dont really understand what you mean. But i do recommend jelly bean. I do think it is an improvement over ICS
Battery life is pretty much the same for me but I never really got as good battery life as you suggest there anyway with ICS. If it is 100% before i go to bed, when i wake up its around 97%-98%. What you can do is turn on airplane mode before you go to bed to save some battery.
