What's a ROM? - Epic 4G General

They just seem like a mushup of things the developer did...like, say, using the mixup kernal and releasing a ROM where everything is stock except there's no drm...wouldn't I accomplish the same thing by pulling and pushing and flashing things?
I'm not getting at anyone here, I'm just curious is all

These aren't actual roms, they are more correctly should be called distros. The devs are more really just modders. I guess the incorrect nomenclature just got stuck.

In some instances we can actually improve the system rather than just adding to it. For instance, every application in my ROM has had every PNG texture losslessly optimized which results in about a 25% reduction in overall size. Reduction in size results in better memory conservation and in theory a faster phone overall.
That's just one example.

Voodoo or Non-Voodoo

Has anyone run the voodoo-ed superclean (either 2.2 or 2.3) in comparison to the it's counterpart non-voodoo-ed. I'm wondering if there's any noticeable difference. Or in other words if lagfix is worth it? I jumped from dl30 to 2.2 voodoo, and I was blown away, but I can't get my phone to act right, and I'm wondering if I should just wipe clean and start fresh with 2.3 non-voodoo-ed. Thanks for any comparison results you guys can provide.
Personally, I haven't had great lick going back and forth between voodoo and nonvoodoo. There are plenty of instructions on here that state how to do it properly, however. And you always have Odin (that is if your USB port is working...) to restore to stock if necessary.
I tried both, and personally I saw a huge improvement in speed and overall responsiveness with the voodoo version.
If you really want to be blown away, try jt's aosp v 0.7 -voodoo version. Its what I'm using now, and it will take alot to get me to switch.

Is jt's AOSP completely finished and stable? I'd run it but I don't recall it being 100% complete...
Unless you need camcorder or mms, for the most part it's complete. I think the benefits of how fast it is and how good it looks outweigh the few things that don't work.

Thank you.
I could be mistaken but I'm fairly certain that Jt's .7 is running on eb01 or something like it. He has a custom kernel for the rom so I don't know how it works out, but I'm under the impression that it is eb01 at the moment, and you can use the eb01 baseband regardless

Hellllll with tv screen off animation and setcpu!!

Screen off animation help and setcpu with cm7!
My tv screen off animation worked for probably 1 hour before I downloaded apps... idk why it's gone but I would love to get it back without widgetlocker.
Also I have read people getting 15 + hours of battery life using setcpu I just want to know what I should set it to and if I should use screen off addition. Thanks

hmmm, i had same problem with the tv screen off animation. i don't use setcpu i am using kifno's tweak. he has two, one for more battery life and one for more performance. reason i mention it is that when i flashed his tweak, suddenly my screen animation came back and has stayed.
Yeah ill try his tweak. I'm gonna go with battery rather than performance. Will I lose all my apps? It says I have to wipe I'm pretty sure

No you will not loose any apps. Mp= More performance and Bl=more battery life. Don't flash both. Just read the thread carefully, choose one and flash from recovery.

You should really take the time to read the whole thread or as much as you can to understand how you are modifying your phone setup. The risk/benefits will/should be posted by the OP. Also user experiences and feedback will be posted there as well.
With that being said.
The BL mod will take time to setup you will not see an immediate extension in battery life untill you have properly calibrated your battery. However you should experience a boost in 3g dl/ul
speeds. This will be minimal compared to the Mp mod but should be better than stock.
The Mp tweak results should take effect immediately hence the name of the mod.
Basically you can't have both. Its either one or the other. I run the Mp tweak and it might help with your animations. This is my understanding of the mod. To gain a better perspective hop over to the thread and read or Pm the dev. He's on break now but I think he's answering Pm's. He's quick to respond and is a cool dev.
Well Good luck. If you want to try a mod and have read upon it and need any help let me know if I can I will.

Alright thanks. I'll tell ya how my battery life is. Still looking to get that tv animation back so if you find out let me know

Blandroid on N1

I just noticed, blandroid rom on the rom manager menu, has anyone tried it on N1? I'm using cm7 Rc4 and I know you'll all say stick with it, but I'm still curious.

Seems like a plain stock ROM, nice to see to be honest.
Noticed the same thing, but was wondering what all it supports, site doesn't say much. I.E. what kernel it has/supports, TB alert stuff like that.
Hopefully the dev comes and explains what all he's done.
Well, I flashed it, for like an hour then when back to cm7 using the recovery I made.
First thing, market didn't work.
Secondly it didn't have the extra apps cm7 has, which I expected, but I instantly missed theme chooser.
Thirdly it wiped my contacts list.

First. The market issue is probably a wipe issue as I had the same problem with two different MIUI GB ROMs.
Secondly. That would be the lack of bloatware mentioned above. It's like stock android, so not sure why you even flashed it if you wanted bloatware.
Thirdly. It didn't wipe your contact list you didn't sync with google, becaue all of your contacts are backed up there.
You know what, I knew that'd be the replies I got, to be honest I'm curious of any rom that 1might increase battery life, currently using 85% over 10hours!! And of course the dreaded wonk which is seemingly inherent with cm7.
I couldn't force Google to sync with my phone, all my contacts are stored with Google you're right there.
Btw how would I get the market back?

I think it is another keyboard app. When you go to change the keyboard, it lists something in all Asian symbols.
I just deleted it and I have not noticed any difference with how blandroid runs.
The wonk was almost fixed on latest release of cm7. If you don't have the latest version, try it.
Sent from my Nexus One using XDA Premium App
Nearly fixed isn't fixed. The problem is really dragging out and these stock ROMs are showing that its fixed with them. Wonking isn't the only issue at the moment either. There is still problems with the sound levels after docking the phone sometimes where its maximum level is halved etc.
CM is an ace project and I truly respect the guys and their efforts behind it, but CM7 is very buggy, and when it starts to affect the ability to take calls its hard to use it.
Oh! Thx for the reply. I got scared and ran back to cm7

What sort of battery life do you get and is there good support from the Dev?

Sent from my Nexus One using XDA Premium App
I like!
Went for this until the CM stable kills the wonk; now I may not go back. I haven't used it for long enough to know about stability. I think of it as pure AOSP, but already rooted (and a just a few essential CM goodies).

So far, I haven't found anything missing I need.
And if you want a bit more eye candy and customization, just install launcher pro or adw.launcher from the market.
I give it thumbs-up!

Battery Life/Temp When Running ICS

Recently rooted my phone and have used a number of different ROMs. The ICS ROMs for this phone seem to heat up my battery and drain it quite quickly. GB ROMs don't seem to do that. Is that the nature of ICS for the Glacier?
I'm just wondering what other users' experiences with ICS are.
Thanks.
Its a known issue with ROMs that have the 3.0 kernel. I know that the devs are looking into a solution AFAIK no eta yet.

He said ICS, we don't have any ICS roms with 3.0 kernel (because we would have to re engineer the rom.)
To answer the OP's question, i haven't been on gingerbread for a long time, i don't have a problem with ICS, check your clock speed, your governor and your battery. What rom are you on? And are you sure its not JB?
I was using Glacier_One_V_1.3. Sorry, I'm a noob at the whole kernel/governor thing so any assistance would be greatly appreciated.
For now, I ended up switching to Skytouch (the i06 port to myTouch) as my ROM.

So, after doing some research, I downloaded System Tuner and changed the Governor to Smartass V2 with a High Threshold of 1.02Ghz and a low of 245Ghz. I'm going to see if that improves my battery life.

I'm very happy with battery life when I use Synthetic.Nightmare's SyNthetic_aospX 1.0.0-MR1SG. Is it as good as CyanogenMod 7.1? Hard to say, but possibly not. Haven't noticed anything in terms of heating, though. Newb, so not sure about kernels (except as they relate to linear transformations) but I think I have to be using aosp(x) kernel with that ROM...
My two cents
I am using Glacier_One_V_1.3, very happy with it. waiting for a new kernel about to be released.. and I am sure it'll solve a few issues maybe flickering screen/flipping lock screen and maybe the heating problems. Who knows
Battery life is good for me. yet thinking of getting an alternative battery. Maybe it'll get less hotter.

Best kernel for a "regular" user

I'm not much into over clocking or under volting and all that stuff, I just want a smooth kernel, without connection issues, and bug free as possible.
I only usually change I/O and governor's, which is already available on my current kernel and ROM so that's fine.
Any suggestions?
Oh, and works with AOKP

There is no "best kernel", its not a competition. Search in the Development Thread and try them out. Then choose what suits you best in terms of performance/battery.

OK, you obviously took my question out of context, let alone did you even read my question? I did search in the development thread, or else I wouldn't post this question. Out of other peoples user experience, I want to know what kernel was best for them, excluding the over clocking and undervolting features. And BTW, I'm not looking for battery specs as every user is different.

Oh sorry then I must've misunderstood it.
I am using Francos r51 kernel. Because.. eeerm .. the batterylife is just amazing without sacrificing performance.
These "Best kernel" threads usually get closed. Just giving you fair warning. I'm using Harsh kernel. It's great.
*obligatory there is no best kernel statement*
For 'normal' users I would recommend intersectRaven's kernel. Requires almost no user intervention - you can of course change governor and I/O scheduler - and is easily as fast as stock in performance but with much better batter.
All my opinion of course, yours may differ.
Currently I'm running AOKP with faux which is giving me the best battery life I've ever had. About 5-6 hours of screen on time!

If you're a normal user, then why do something abnormal by flashing a custom kernel? There's always a trade-off. You might gain a bit of battery life, but you're more than likely to gain a bit of quirkiness. Furthermore, some kernels like Faux's overwrite system files, whereas other kernels like Franco's use a different ramdisk. This may cause problems if you subsequently flash a kernel that replaces only the zImage (kernel) and which assumes that the ramdisk is stock.
there is no best kernel , all of those are good

I like this topic, I was actually looking for it.
I'm not an advanced user, I learnt pretty well how certain things about android work (i.e. I've used custom roms since I first started using a smartphone) but I know little to nothing about other stuff, like custom kernels.
Now... let's say that I'm not comfortable messing around too much with aspects of the kernel that I don't fully understand...
- Would you suggest a reasonably simple custom kernel that you believe is better then stock even if you don't mess around with it very much? (to me, and I believe according to iAndropple too, this is not a topic about "the best kernel")
- Would you suggest to stick with stock?
- Should I search for guides on YT or on the Internet so that I can have a better comprehension of how a kernel works, what is relatively safe to tweak and what is not?

I tend to agree with this statement, one has to try and learn, but maybe floepie is right, using a custom kernel is not the same as using a custom rom, and could be dangerous.
I know noobs like myself can be annoying, but I'm just seeking for advice and trying to learn new things here, any answer is welcome.
Thanks for the responses guys, and I'm just getting used to custom kernels, so I just want a low user based kernel, so I can learn my ways from there. I LEARNED how to flash ROMS and ADB stuff, but I didn't learn custom kernels "yet" to a full extent.
Hope you guys get what I'm saying
