[Q] Some questions before instalyng CM7

I am seriously thinking about instalying cm7 nightly on my phone. But before i do i have some and i was thinking maybe you can help me out.
1)I was readying that everything works exept for the radio. Is that true? and how does the gps work as good as in gingerbread?
2)How is the battery life compared to the stock gingerbread rom?
3)Is it stable enough for every day use?(i don't mind if i have to "adjust" something here and there i just don't want to miss my cals amd sms).
Thnx in advance.

hi.
1) everything except radio is working. Radio is even semi working on the latest builds.
GPS is sometimes stable and sometimes not. Can't day it was better when I was on stock ROM.
2) there are some battery issues, but I can make it last a day with moderate use
3) wouldn't say so. It is still in nightly build and no stable release is available yet.
I'm using it as my daily driver, but I don't mind some bugs here and there since the ROM is blazing fast.
My 2 cents on the matter

I had it installed for about a week. Didn't try the radio but everything else seemed to work.
Was a bit unstable at times but I could live with it. I couldn't live with the battery life though so reflashed samsung firmware.

To answer all three questions ...
1) FM radio works in the most recent builds. As GPS is about the same as on stock roms. The hardware is the hardware after all.
2) battery life is just? Like on the stock rom ...it depends on a lot of factors. If you are one of those people who claims to get three days on a charge, then you will disappointed. Most users get between a day and a day and a half of normal use per charge with much greater performance than on stock roms.
3) I feel it is ready for daily use if you are the sort who enjoys regular updates and tinkering . However ymmv so the only way to know how you will like it is to flash it and see.

what he said ^^
battery life was fine for me and i last used CM about 2 months ago !!! so it must be even better now
its the same as MIUI except from the layout, and i been on MIUI since CM7 - 2 months. and it is definitely stable enough for day to day use.
everything works for me and fm radio does too !! but if it acts up, i just switch data on and listen to radio online, so thats no issue for me.
I would HIGHLY recommend you try it, the speed is well worth the little bugs. it will blow you away compared to stock / samsung based ROMs.
and if you like CM7 soooo much, take 10 mins to switch to MIUI and you will be even more amazed
and if you dont like it, just go back to stock. at least you can say you have tried it

Big thankyou for everybody that answer my questions.

True.
I will try it first thing in the morning. since i have to recharge my phone.
rschenck @ i am going to fallow your tutorial, but i noticed you sad that you need a froyo bootloader, why is that?
And 1 more thing: If i want to update cm7 do i allways need to reinstal all the apps or i can update the phone without wipeing all the data?

you can update without losing your apps, thats not a problem
and as for the froyo bootloader, you need this for sd card reasons mainly, amongst other things.
sometimes people cannot use internal nor external sd card, because of not having a froyo bootloader, thus resulting in most apps not working, camera not working and so on.

I was just like you... and i have decided to flash CM7 two days ago:
Really surprise, it's fast and stable.
No problem with call/sms.
Gps and battery life is ok like samsung rom.
Heavy 3D games like Dungeon Defenders work well.
But no TV-out, it's my only problem with this rom...

well i don't use the tv-out feature so i think it is ok.

[Q] Getting an IS tomorrow or on monday...

But, where should I start?
Is it really necessery to flash a custom ROM, or is this phone snappy enough with Sense (but I'll probably use GoLauncher or LauncherPro, I only use 1 homescreen...)?
Which tweaks are really necessery to make the phone's battery survive for more than 24 hours, when texting pretty much?
Perhaps the phone's battery survives even though I text a lot (between 100-500 texts/day, depending on how bored I am)?
How's the vibrator in this phone, can I have it in silent mode and have it in my pocket and actually notice when I get a text?
My current phone's vibrator is pretty crappy.
I've been browsing this forum for some time now but haven't found anything that answers my questions... I come from an Acer Liquid A1, without CM7 or MIUI that phone is probably one of the worst phones ever done. But, I sure hope this community is just as active as the one the Liquid had, and still have
(lol, "is this a question?" eh, it's many questions... )
oh, and one more thing; is this device brickable? or can you always reset it to default, like with the liquid? if something f...s up you can always boot into bootloader and reflash a *.bin
Help a newbie to get started, and flashing things and stuff is nothing new. Only the way to root it is new for me... :/
Regards,
Me
(hopefully I haven't missed a thread that answers all my questions, but of what I've found I haven't found anything that actually helps me. if I've missed it, just link to it and remove this thread )

I don't think you need a custom ROM. See if the battery is good enough for your needs. Remember to drain the battery completely multiple times to "train" it.
On another note, why get such an expensive phone, just for texting? It's going to drain a lot of battery while you are looking at the screen. Might as well go for a feature phone imo.

You should easily get 24 + hours if all you do is text mainly. Just remember to turn data off. It will help make your battery last longer.

Well, my current phone dies pretty quickly when texting a lot. Today it went from 60% down to 5%, and I woke for 11hours ago and have been texting ppl since then.
And I'm buying a new phone since my 4 touch-buttons on this one is getting really weird, they only work sometimes and yesterday they all died so I was stuck in a conversation and had to reboot to get out of it.
And sending texts and stuff is what I mainly do, of course I browse the Internet, play games and everything. During school and such I only text people, and a lot. So I pretty much needs the phone to make more than 24hours without charging it, even though I text a lot and listen to music.
@NardVa;
Won't be a problem. Already thought of that
Thanks for the replies

I was going to suggest flashing, the stock rom is garbage for battery life. Android Revolution HD seems to be one of the more popular choices, but of course Cyanogen Mod is there if you decide the Sense UI isn't your thing

I've made up my mind now, I'll use the official GB ROM for a couple of days/weeks/months (basically untill I'm tired of Sense 2.1) and then flash a Sense 3.0 ROM and hopefully I can understand which one of all those RUU's that's made for Europe too when I'm bored of Sense 2.1
You don't happen to know how it is with bricking this phone? Can you always reset it to stock, or can you actually brick it for real so it's 100% unusable?

[Q] Need your Advice guys. Thinking of buying the 2x

Hi guys
Basically I've been a windows mobile user for ages now, had the omnia i900 for quite some time now, and i think its time to move on.
I've been thinking allot of buying this phone because it has an excellent value for money. Simplyelectronics.com has it listed for like 300 euros and here in my country(Cyprus) its 550 or something, which is ALLOT. So I've read allot of reviews and everything, but I would like to know what YOU guys think, how it is for everyday use.
Any problems or annoying stuff about it, and also if it's easy to use and easy to carry around, although is that big.
I really appreciate it.
Cheers

I changed to a custom rom almost immediately after I got my phone, so not sure about the stock software. I am using DJDroid rom atm, and I like the battery life and have no problem with everyday use.
It should be the best value for money phone until xiaomi phone arrives.

Hardware good, software bad, customize it and it's a goodun.

I'm also very interested in this phone. This is mainly because of it's killer hardware as well as the poor software as this has caused the price to fall to a reasonable level. Poor software can easily be fixed by flashing a custom Rom/kernel.
I also think it looks very nice

Thanks guys.
You're great.
How bout the feel of the thing. Does it feel bulky, or thick?
What do u think

It is 10.9mm which is slim, even to todays standards.

Just placed my order.
Really great value for money.
You guys have been really helpful, cause i read allot of threads about random reboots and stuff, and i thought they were hardware issues or smthn.
Anyway
Thanks a bunch
Cheers

I would buy the 2x. With the latest stock rom, it's smooth and stable.
I love it!

I dunno what anyone has agaisnt the stock rom with the exception of the bloatware crap that lg bundle in with it i havnt had any issues, no overheating, no random shutdowns or restarts, its been fast and responsive.
Maybe some people just dont know how to use their phone and have to get cyanogen to handle it for them.

Its a good Handy.
You can buy it.

I also think it's a great phone when you look at its price. I am really happy with it

its great if you dont use bluetooth audio and radio. otherwise dont buy it!

BT Audio? Really? Just A2DP or other audio-related profiles?
I was aware of A2DP issues with certain ROMs, but are you aware of any issues with the HSP (headset profile)?

good
im satisfied with my O2X and many developers are supporting this device now including extending battery life and camera quality. I'll say you should go and place the order

Feels good actually, not sure what others are about, been using mine with the rom it came with, has 2.2.2 on it and gets 3 days per charge easy (still over 50% battery at end of 3rd day), and have not had any issues with it.

Do you turn off your phone when you don't use it?
I have no idea you get 3 days out of it. I play 3 hours on mine, and battery is gone. What ril, baseband, rom, settings you use?

it's one of the best phone out there.. those said this phone s*cks must never tried to fix, so they given up this phone.. all you need is root, custom ROMs, and there you go.

[Q] CM7 battery is horrible... how are people getting good results?

Wanted to give CM a shot again, getting the same results as the last time i tried it.
My results with pinnacle 1.2:
Everyday I leave for work at 630, and when i leave at ~3, depending on how much i use the phone, im usually at 70-80 percent.
If i dont use my phone at all, and am in an area of good service. It usually drains at about 1% per hour.
My results with CM7 nightly - stock kernel
I left for work today at 630, have barely used the phone, because i wanted to test its standby drain, and im already at 70 percent (down 30% in 5 hours) The performance is great, but i cant live with battery life like this.
Is there anything i can do to fix this? And please dont tell me to do things like turn off sync, and all that crap, because i bought the ****ing phone in order to do these things. If i wanted a phone that was just a phone, i would have gotten a blackberry or some other regular phone.
If i can do these things in pinnacle and get good battery life, im not going to give them up in cm just to get battery life that is closer to pinnacle.

Just my opinion, but if battery life was better for you on another rom, and that's important to you, why switch?
If you're really looking at CM7, maybe you should research what modem you had on pinnacle and see if there is a CM'ed version of that one available. That alone could be part of what you're seeing. You could also try a kernel like Glitch and see if OC/UV is something that would help. Also take a look at the battery stats and see which processes are near the top - that's usually an indicator of what areas of the phone you should focus on first.
And, although I understand you're frustrated, please watch the language.

Because as stable and good on battery as it was, i just needed something different. And dont get me wrong, I love CM7. Its awesome besides the battery issue.
I started this thread before i flashed to try to get an idea of what i should use: http://forum.xda-developers.com/showthread.php?t=1347952
Someone did make that modem for CM, but from what i hear, the call quality isnt great, and the other person hears a lot of static. Weird because its awesome in Pinnacle.
Going to try glitch, but i wanted to get an idea of how the stock kernel worked before comparing it to glitch. Probably will end up doing a OC/UV, but i wanna at least see if i can get decent battery first before i do that.
Cell standby is accounting for double of what anything else is listed is, which hopefully means that if i get a better modem, then it might fix that.
And didnt mean to come off as an ass, i just hate when people suggest things like that to fix battery issues. Ive read in other threads people suggesting that, and really, why even have a smartphone if your gonna limit it that much? I dont go crazy with any widgets or any apps that would cause that, but turning off sync and things like that are just crazy.

Sounds like a good plan. If you haven't checked it out yet, I think that Oxicottin has a list of modems and where they work somewhere in the Dev thread - that might be a place to start your search for modems.

you call quality sucks because CM7 lacks the audience chip support that is native to all I897 ROMS.
So again call quality and great battery life or CM7? You might want to try some of the newest KK2 Rom builds like Luminance or Legendary.

[Q] I wish Samsung would release official JB!

Hello everyone, as the title suggests if only Sammy released JB for my phone. I love the look and feel of it on the S3 but just dont like the phone, its too big and bulky IMHO. I am eagerly waiting for the S4.
Anyway, the reason for the post, i have been using CM10 on my I9000 for the last couple of weeks, i actually love it ands it actually pretty stable but and its a BIG BUT the battery drain finally killed the last remnants of patience i had with it. 12-15hrs on one battery charge is just not satisfactory.....so ive gone back to stock GB 2.3.6 and already the battery life has dramatically increased. Is this a firmware issue or poor hardware I wonder.
In anycase i would like JB back on this phone but I would like at least the same battery performance as GB, so my question really is about which JB ROM i could use?
Anyone got any ideas, recommendations or rom-avoidance advice? Anything would be helpful and much appreciated.
Thankyou!
G.

Use a different modem, and try a tweakable kernel like Semaphore. Also install betterbatterystats. That will tell you what's keeping your phone awake. I get two days out of my worn out two year old battery on the latest CM10 with low to medium use. Back on ICS, before I changed the modem, a RILJ wakelock would keep it awake pretty much all the time and I had about 12-15 hours of battery life. I'd rather Samsung stay as far away from software development as possible because nothing they have ever done in that department has been even remotely usable.

I also wish Samsung would release official JB for the I9000, but I'm afraid it's never gonna happen. They have left the I9000 behind it seems, and I think Gingerbread 2.3.6 was the last ever official update. It's custom ROM's from now on for the Galaxy S.

I wish i could fly.

try a different modem??? try a different kernel??? i apologise i dont really know what you mean....
1. are you suggesting you can change the modem - how on earth do you do that??
2. ive heard the word Kernel being used but actually dont know what one is or what it does. complete novice to all this im afraid - i know about ROMs (for JB) like Cyanogen CM10, Slimbean and HellyBean etc etc, and have actually heard of this Semaphore but not actually knowing what it is!
Can you explain what this all means at all ?
btw - i get your point about Samsung especially on thier own non-andriod phones. to be fair the stock roms work flawlessly on my i9000 and the UI progression from Eclair to GB is staggering...even if it is cloaked as Andriod development....still looks and feels better than any Iphone. Thats what i meant by i wish Samsung would of developed ICS and JB for the I9000.

What helps in terms of battery life CM roms is:
-using 2d as much as possible and 3d only when needed (browsing, downloading apps etc). Problem is that 2g mode will not allow you to use data and make phone calls at the same time
-disable location services or at least gps when not used
-freeze/remove apps you are not using (stock email, talk, gmaps are battery drainers)
-disable CM built in app&data backup and use TB instead
-use lowest acceptable screen brightness
-buy a brand new battery

Hmmmm well all that seems like a gr8 idea but then what would be the point of flashing CM or any JB custom rom if i werent going to be able to use the features within it, like you would an S3 ??!!!! Kinda seems pointless to me... At the end of the day JB is the latest and greatest version, youd want to use and explore its capabilites as much as you can, without comprimising hardware performance..
Surely there must be a non battery draining and stable version of JB out there.......:crying:

@up
Totally agree with you. These are just workarounds that make you able to survive a day without recharging but at the same time limit user's satisfaction from owning a multifunctional device (eg no location and gps = no Google now). I'm switching to SGS2 that will get official jb shortly so will see if it gets better battery life but I do not expect miracles. The only hope in Google and Motorola cooperation. Motorola's battery + updates from Google must make a great combo

Before anything else, please install CM10.1 (http://get.cm/?device=galaxysmtd), CPU Spy (https://play.google.com/store/apps/details?id=com.bvalosek.cpuspy) and BetterBatteryStats. (http://forum.xda-developers.com/showthread.php?t=1179809)
Now in BetterBatteryStats, look at the "partial wakelocks" near the end of a day's charge and drain cycle. This will tell you what was keeping your phone awake. My money is on RILJ being at the top of the list and active for several hours. If that is the case, you need to change your modem. Check CPU Spy as well to see how much time your phone spends sleeping when it's supposed to.
Modems
The "modem" is basically like a driver file for the phone's radios and such. (Cell radio, WiFi, GPS, etc) It tells the phone how to use those things. So some modems are less efficient or not tuned as well for your specific carrier.
http://soggycashew.weebly.com/i9000-modems.html - Here is a collection of modems packaged in Clockwork Mod zip files. If you were able to install CM10, I'm sure you know how to install them.
Go to the "i9000_release_dates.txt" file and try the most recent one. If you have an i9000M which supports the 850MHz band, only use the 850MHz-capable modems. Likewise, if you have a regular i9000, don't use those. Testing may take at least day or so each. If you're still seeing a RILJ wakelock time more than about 20 minutes a day, try the next latest one.
Kernels
The "Kernel" is sort of like the BIOS in a PC. It starts up first then Android runs on top of it. Android communicates with the kernel, and then the kernel communicates with your phone's hardware. It runs the screen, sound chip, vibrator, radios, everything. Some kernels are basic and only include what they need to run the phone normally (like the stock Cyanogenmod kernel) and some are made to let you change all sorts of settings of how they operate.
I highly recommend Semaphore JB for CM10.1
You'll find that here: http://forum.xda-developers.com/showthread.php?t=1786220
And the app to change settings here: https://play.google.com/store/apps/details?id=com.semaphore.sm
For improved power savings, use the app to turn on Deep Idle, make sure WiFi PM FAST is disabled, and you may as well turn on fast charge. (no power saving, but a shorter charge time is nice)

Now this stuff is pretty simple, but it can be overlooked. Make sure to turn off apps that auto-update or at least lower their update frequency as much as possible. These are brutal for battery life. With your Google account, only enable sync for things you NEED to have updated automatically. Like Gmail and Chrome. Things like Contacts and Calendar you can update manually whenever you want but you probably don't need it constantly ready to sync. You can also do things like lower the screen brightness and turn off the fancy stuff, but I don't bother. 100% screen brightness all the time for me. I'd rather have a good experience than another couple minutes of battery.
I really hope this all helps and you can get on the latest ROM without the crippling battery drain these phones sometimes get. And you have the right idea about keeping all the effects and things on. Everything's active when the screen is on anyway, so battery savings will be negligible. Good luck!

All operating systems have a kernel, Windows, OS-X, Linux, whatever, it's just that in a closed system like Windows no-one knows its specifics or can do anything to it, whereas Linux's can be.
(Take a look at your screen when turning on your phone, the kernel image is not the first you see)

They should do that as soon as possible as the JB thing means a great progress in Android development. The new OS is really faster, covers alot of minuses from the previous versions and Samsung, being so good in the last few years they should stay in touch with new, good ROMs if they dont want to begin to have Google as their second conquerent.

I wished that samsung have followed apple's example and released the last version of OS for every phones which work with that.

Apple just stops updating devices for no better reason than they want to force upgrades, it's not like the old devices wouldn't work. Like what Samsung did here, except at least porting Android over would take a little bit of work/time. Still no better though. Apple also holds "features" back from older devices purely to market something new on their otherwise indistinguishable upgrade. (like Siri)
Nobody, including Apple, should follow Apple's example. I think Samsung should stop bothering with bastardizing Android and just hand the drivers over to the devs here, because they actually make software people actually want to use, and enjoy using.

...its very sad that i9000 won't get ( >= ICS), sgs1 is still very good phone...

Wish, you were here...
successfully using cm10 stable without any customized kernels , no battery drains, just do a factory reset from firmware settings, and you will be happy
