[Q] Netarchy 4.3 SBC Kernel

I flashed a new kernel, netarchy 4.3 bfs no havs SBC and no undervolting. I had read before that it can take up to a few days for your phone to stable out after flashing a new kernel. I don't have any major issues, just get some really bad lag here and there. So, is it true that the phone takes time to become stable again? And if so, will the lagging go away in time?

Maybe...but then again it could be the kernel/rom/your phone combo. They say to wait for a few days for the kernel to level out but when I installed netarchy 4.2.1 cfs more havs smartass, my phone was zippy from the first boot. And never got slower or faster. So you could try to wait it out but if you find the perfect kernel for you phone it will
Probably be good right away. Once you find a good one I would run it for every rom you use. I've been on sbc net 4.2.1 for maybe a month and I'm not goin anywhere!!
I used the site evobenchers.com to make my decision to go with 4.2.1 it seemed to have the perfect mix of low battery drain and good speed and to my surprise it worked.check out the site and use the graphs to make you're decision. Good luck
Evo - Myn 2.2 RLS 3 - Clockwork - HBoot .76

As of right now it doesn't seem to lag a bit. However, I disabled all window animations so that's probably the reason why. It seems to be doing fine though. I'm really loving this battery life, I've spent about 30 min texting, on Facebook, and playing angry birds. Still sitting at 100%

Yeah...it's a really good kernel.

[AOSP] Q Which kernel do you prefer? Savaged Zen or Tiamat?

Just a show of hands basically, because both of these guys keep updating their kernels back to back it seems.
I personally use tiamat 3.3.3, these kernels have been good on my battery, and are pretty fast.
Which do you prefer?

I agree Tiamat has been awesome for me...i had too much chopiness with salvaged-zen and i personally like the SBC addition to kernels and they stopped updating it with SBC i saw...but as far as battery life and smoothness goes, i choose Tiamat, hands down.

Tiamat is great, but there is something up with bluetooth audio in his kernels. It's like the audio doesn't use the mic to auto cancel sound or something. Can't really put my finger on it. All I know is that when talking to the fiance after work on the way home in the car on yesterday, all she heard was road noise. Switched back to SZ and today its gone. Gonna wait a couple of revisions and try it again

Savaged Zen here. I tried Tiamat for a while, but I kept getting random reboots no matter what I tried. The first SZ I used was .9 bfs havs, and it worked great. Currently on .1.2 cfs and no problems.

Savaged Zen All the way. Especially now (this is from march) the 2.6.38 line, im on the newest 2.0.2 and Its super smooth, I havent seen the slightest hint of any instability, and it rips on benchmarks and games

Any Tiamat kernel sends me into random soft reboots, almost once every half hour or so. I can get it to stop by flashing ViperBoy's raise voltage script. Then it runs quite smooth and stable, however battery life sucks for me (probably from raising voltage) Savaged Zen gets my vote, it just agrees with my device way better for some reason, especially 2.0 CFS.

SavagedZen works better for me than Tiamat. Had them both and both worked well but I like running BFS on my phone and the SavagedZen governor is a great governor for battery life and performance.

timat is really stable on my phone, but sz has always been much faster... now that he new sz fixed my problems, im staying with it

I'm a fan of savaged but I'm cool with tiamat, still looking for a happy home. Im on SZ 2.0.2 which is giving me good battery life but still has the BS wimax bug. I ran tiamat a couple weeks ago for a few days but I swapped out once the random reboots started. Wish CM7, one of the best roms, also came with the best kernel.

I always do a full wipe factory reset and wipe the davlik cache. Cm 703 has more built in options than omfgb 120. I like it so far. I have heard the two were very similar now I see it is true. Right now it's a coin toss for me. Ill give cm a few days to cook in and see if there are any glitches. I know in the last 3 days on omfgb I have had no problems at all. Just gotta give cm a shot since the rom support seems to be much greater than what I've seen on omfgb.

It's great so far except huge lag when swiping screens, but no lag when using the next/previous screen buttons.

its not lag i dont think i think its just smoothness

[Q] Kernel for Miui

I just flashed the updated Miui ROM onto my friends Incredible (I am improving it for him) and was wondering which kernel would work best with it. I have heard that Tiamat is one to consider, but I don't know if it works the best with Miui.
Thanks in advance!!!!!

Tiamat is great, but I've been really happy with the included kernel. YMMV

Oh that's right, there is a kernel included with Miui. lol Forgot about that. Does it install automatically when you install Miui, or is there something separate you have to do? I am a Miui noob and just want to make sure I do everything right. And has it improved battery life? That's why I am asking about the kernels.
Guess I'll keep Tiamat on the back burner for now.
Thanks for the response.

No problem! Yeah, it installs along with MIUI. Give it a few days, I think your friend will like it. I'm running it underclocked to 800MHz on the stock kernel and it's smooth as butter

I flashed chads incredikernal. One thing I don't like about the stock kernel is the charge speed. I am currently at 11 hours 19 minutes with 36% remaining on stock Inc battery. I don't mess with any settings, I let it do it's thing.

Well, if you charge overnight, then that really isn't that big an issue. But I will definitely put that on my list of kernels to try if my friend isn't satisfied with the Miui one.
Thanks!

I've tried Chad's incredikernel and it was awful. Been using Tiamat for the past couple days. I'm gonna be going back to the included stock kernel that came with MIUI tomorrow. I've gotten the best battery life out of that one. I think it'd be worth it to try out each kernel on your own phone for a couple days. Some kernels may work better on certain phones than others.

Interesting. I will definitely try them at one point to see for myself, but it seems that the stock Miui kernel is the way to go. I've been playing with it for 2 days now, and I have seen a noticeable increase in the battery life. I am very pleased.
Thanks for the response.

I always flash Chad's Incredikernal after the MIUI update, but this time I'm test driving the (MIUI) stock kernal to see how battery life really compares after a couple of days. You really can't go wrong either way. But, as posted above, YMMV. Good luck!

Incredikernel #1 with IncrediControl app http://www.incredikernel.com/
I try Tiamat every release but always go back to Incredikernel, Incredikernel is so much smoother. Also better benchmark with all apps and no task kill. Pics for proof!!!!
SetCPU min128/998max @ smartass scaling

Also if you are playing with kernels and want to go back to MIUI stock it is the Official CM7.0 version1. Can be downloaded from kernel manager lite(free) in market. Invisiblek version4 is nice to, its based off CM7.1 version2 with smartass added.

Remember when trying new kernels for best results.. Charge until green, then boot into recovery, then advanced and wipe battery stats, then power off and let charge until green and good to go. This gets the results without waiting 3 or 4 days of charging. Also you wont see the unplug and go from 100% to 83% in 15 minutes.

every phone is different. I have been trying to use incredikernel for months and my phone runs like complete garbage with it. I use tiamat and it blows incredikernel out of the water on my dinc. I have no explanation for this and am hoping one day my phone will accept incredikernel. :-(

Hmm thats weird, reverse your statement and that's me. I tried to contact Tiamat support and they have no support, I emailed them 4 months ago and nothing. Chad only supports the incredible device so I have gotten response back from him in hours.
I have 4 Incredible's all running incredikernel fine. 2 are on MIUI and other 2 are on CM7.1. Three of them are on version 07062011 and I'm running his beta 2

Actually, to recalibrate, this is what I'd recommend.
Charge the phone to 100%
Turn it off. The LED will turn red again, wait for it to turn back to green.
Boot into recovery and wipe battery stats.
Reboot, then unplug.

Best/recomended MIUI rom?

Hello all.
I've been out the loop for a while now, still got stock sense on my DZ but have recently become very interested in MIUI roms. I have a few quick questions I hope someone can answer as after reading the various roms etc I'm a bit confused.
1. How well do MIUI roms work with the hardware keyboard? I'm seeing a few threads saying it isn't totally supported. This is a deal breaker for me really, can anyone clarify?
2. Which MIUI rom? I see there is an official one, but also others similar to official eg MIUIandroid, any particular 'best' version?
3. How is the battery life compared to sense? Does anyone have any current draw figures for screen off etc, my sense draws around 32mA screen off.
4. I assume they come with overclockable kernels, if so, is OC beater or whatever it's called still the best to use?
I'm interested to hear from MIUI users, sell it to me.

1. I've had no problems while using the keyboard with MIUI, it seems to work the same way as before. I have heard some people say that their backlights don't work but mine do. However, landscape is not supported on the homescreen but it is everywhere else.
2. I use the official english supported rom for Desire Z/G2, you can get it from ROM Manager or the MIUI website. I'm not sure about the best one because I've only used the official one.
I don't know about 3 and 4 but I do enjoy using MIUI. It was the first rom I used after I rooted my phone. I used to want sense but because of emoji support and themes I probably won't use another. I do recommend it as I have not been disappointed.

Thanks for replying.
Instead of exact current figures, maybe you could say what your typical daily use is like and what your battery level is at the end of the day?

I've tried miui us and miui android. Both are good and can tell any difference in look feel or performance. Also tried a couple of the miui v4 roms in the dev section. They are really good and give a snappier feel to the miui environment.
V4 is possibly better with battery but marginal. Compared to the stock rom I came from, battery is much improved. No figures I'm afraid as my days vary greatly. Camera is an issue on all ICS roms on the dz/g2 so decide if that's a problem or not.
Enjoy.

Thanks for that.
I'm gonna flash the 'official' miuiAndroid tonight I think, need the camera so the ICS is a no go for now.
As long as battery is noticeably better than stock sense then I'll be happy.

good luck and enjoy. Give it a couple of charge cycles with the CPU adjusted you should see a significant improvement.

i definitely recommend the MIUIandroid version, the translation is far more complete. Miui.us just has faster servers! If you send/receive a bunch of picture messages, I suggest you download my modified Mms.apk from the link in my signature, more info is in that thread.
I've been using MIUI.au v4 for the last few days. pictures are slightly annoying, but if you take two or three, you usually get a good one, but the pictures do have to be taken in landscape.

Well I have been running it for the day and I have to say that I love it! Much better than sense, seems really stable and I love the customisation.
I was going to ask about that mms thing, I'll check the thread out.
As for the battery, it has run down quite quick today but I've been playing with it a lot and expect to need to have a few charge cycles till it settles.
One question though, does the OC/OVbeater overclocking thing work with this rom/kernel or should I stick with set cpu?

Just to give you an answer, I don't know. But it's an AOSP kernel so... it should!

Have you flashed the bulletproof addon? It adds the Vituous OC daemon as well as OC/UV Beater. From there you can operate as intended and should probably have no issues. Personally I've never been able to OC over 1,3GHz on any MIUI ROM, may be the Tiamat kernel for me though...Anyway the highest I'd go on MIUI would be just barely 1,3-1,4GHz! Practically you wouldn't be needing more than 1,2GHz for heavier apps but considering this is MIUI and is a bit heavier, 1,3GHz will cater your needs.
Otherwise, OC/UV Beater will work but it will be limited to just Normal configuration, since the Virtuous OC daemon (which I presume you use?) is not cooked in, hence it can not be configured. You also can't undervolt because viper uv is also not included. If you're not interested in flashing Bulletproof then I'd stick with either SetCPU or even CPU Tuner (switched to this over from SetCPU and liking the fact it has more extensive configuration, as well as less battery drain). You can find CPU Tuner in the market, if you're interested.
Also, battery life wasn't half as bad actually. I find the MIUI Launcher to be a bit heavy and more resource consuming for my use. You can use Go Launcher or ADW if you want though.

Take a look at the bulletproof add on pack. It includes some nice tweaks, one being a kernel that supports OCing.

I will like to second that! Im running a MIUI V4 port by ajhavery and lenny_kano (MIUI_Au 4.0.3 base 2.3.2) and it is working very well. Except my battery life is not as good as the official MIUI ROMS. BTW Angel Camera from the market works perfectly on this ROM with no glitches.

Oh so you can use the bulletproof add on with any miui rom then?
I'm using setcpu just now but I may try cpu tuner. I tend not to overclock to be honest, I'm more interested in underclocking when screen is off etc but I may try 900MHz or 1GHz, it's running very smooth at 800MHz though.

1. Bulletproof addon is for ANY 2.3 based miui. NOT miui v4.
2. The chip in dz/g2 is designed to run at 1ghz. Htc just UCed it to save on juice and market it as a lower spec (that's how I understood it anyway). I find at 800 it just feels a touch laggy. That extra 100 takes the edge off.
Sent from my HTC Vision using xda premium

Does installing bulletproof clear any data at all?
Is it flashed from recovery?

Shouldn't clear anything. I say shouldn't as you can never guarantee it. I've never had any issues. Always a good idea to clear cache and dalvik when flashing anything. And yes, its flashed in recovery.
Sent from my HTC Vision using xda premium

So I flashed this at the weekend and so far all is well.
Though I must admit, I'm not noticing the battery gains I was hoping for, a minimal boost is all. It does kinda seem that it uses more with the screen on than it used to, some comparison figures for those interested, taken using battery monitor widget.
Screen Off
Stock Sense: 31-34mA current draw
MIUI: 28mA Current Draw
Screen On (taken as sitting at homescreen doing nothing)
Stock Sense: 147-190mA
MIUI: 137-230mA
It's probably still calibrating and I never wiped the battery stats. Would there be a benefit in doing so?
Also, I have noticed that when charging, the light goes green when charge is only around 90% done, any news on this?

The light goes green once the battery is > 90%, this is more or less intended behaviour.
There had been a recent announcement by a Google employee that wiping the battery stats has no visible battery life improvement. All it does is wipe the statistics file that shows you what uses your battery. What you can merely do is run the battery down to 20~% (wouldn't go below that as the failsafe might go off) and then back to 100% for 3-4 times, so that the Battery Meter can become more accurate. From there it is ideal to run it down to 20-30% twice every month in order to keep the battery health in good shape.
MIUI was merely created to be iPhone-ish, cool looking, and very user friendly. It looks awesome, inarguably, but battery life isn't it's strong point. I wouldn't be surprised if it draw more than Sense itself, too. ROM's that have the best battery life are barebones. These have a lot of features suppressed in order to save up in RAM as well as battery consumption. There's also little customizing you can do to them.
However, if you want a good battery life ROM that does not cost you anything in features, you should try Tsubus' ILWT CM7 ROM. It is a CyanogenMod 7 based ROM, that has been fine tuned for speed and battery life alike. I've been a user for a long time and the phones takes me easily through a day with plenty of juice left (about 40-50%). You will have to go through the above meter calibration process again.

Yeah I know and don't get me wrong, MIUI gets me through a day no problem, maybe I was just being a bit too hopeful.
Have to say though that I have fallen in love with MIUI, I can't imagine using another rom now.

well if you are looking to use the bulletproof addon then i made a rom myself with some mods included in it... you can check it out from the link in my signature...
