Unique Question - For Devs (wifi only evo 4g roms?) - EVO 4G Q&A, Help & Troubleshooting

Hey everyone!
Just got an EVO the other day and I have a unique situation.
I'm not utilizing a carrier, I bought this phone from Craigslist, works great, utilizing google voice and groove ip for sms/phone with Verizon Mobile Hotspot for internet via wifi/tether.
That said... I'm curious about phones with similar hardware and flashing roms/kernels.
Is the radio in control of my wifi?
What I mean is... is it possible to flash other roms from other parts of XDA with similar hardware, such as the Nexus One? The research I did tells me they have basically the same hardware so I was curious.
My main reason? I am utilizing CM7 but unless I missed something somewhere, there isn't really an AOSP rom for this phone that is UV/OC? I've seen the sense ones but that's it.
Just curious what you guys might make of my situation and suggestions you may have for me? I almost feel like I'm in unchartered waters lol. Just need wifi to work so I can tether to my hotspot and of course the speaker/mic to work for calls, then it's just a matter of software/apps etc...
Any ideas, suggestions or questions are welcomed. Thanks!

No. Don't do it.

Very insightful, thank you so much.
I guess I should note. I'm not an idiot... I just don't understand development inside and out... If you said "it won't work because the flux capacitor won't jolt to 1.21 jiggawatts" (that's a Jay-Z measured watt) then I would take that, but your response was very unwarranted.
Again, thanks for the input.
If any DEVS have an educated answer I would be greatly appreciative

If you flash a rom from another phone, you will either get booloops (if you're lucky) or a very nice paperweight / brick.
Many of the roms in the evo dev section are ports from other devices that take months to complete so they are safe to use or even boot on an evo.
So to reiterate, don't do it.

I'm a Sense guy, and I'm assuming you want AOSP so I'll tell you what I run when I do run AOSP, it never fails me
Deck's ROM or MIUI with Tiamat 4.1.0 SBC kernel
The kernel would be in charge of UV/OC and Wi-Fi
Use Amon Ra as recovery
Wipe everything except for SD card twice
Flash ROM
Navigate to mounts menu and mount everything except for SDext
Flash kernel
Flash Vipermod (allows undervolt)
Reboot.
Reboot.
Go to terminal and type:
su
vipermod
Choose how much you want to undervolt. And usually I undervolt by -50
Type in 10 to save changes.
Reboot.
I almost always underclock. To OC/UC, go Settings-Advanced Settings for Deck's and set at boot or Download No Frills CPU for MIUI (have to go to Superuser app and hit menu button and allow root)
Do not flash anything from a different phone... Mount points are different, different kernels and it would be an absolute mess

[Q] Would you mind helping a Android noob?

Ok,I'm new to Android, fresh out of Windows Mobile and might not know what I'm talking about, so... here we go,
I'm looking for my dream ROM, and kernel combination
Is there a ROM out there that has:
Delicious Froyo
4G Enabled
Can use Bluetooth controllers - (Wiimote, MSI BGP 100) [I guess that means it'd have to be Senseless?]
Retains its HDMI out functionality
Uncapped FPS
Over 2 multi touch points
Stability - Doesn't crash often
Decent Battery Life - (More than 5 Hours)
Swype Keyboard
802.11N Wireless Support Enabled
Overclocking support would be nice, but probably not necessary
I'm currently running Fresh Rom, but its starting to seriously lag after a few weeks of use, I guess its because of all the apps and widget mods I installed. And stupid Sense keeps starting up when I start my phone, even though launcher pro is my default home.
So I'm ready to flash another rom to have a clean start, now that I kinda know what I want.
There isn't a ROM with all of that
Looks to me like most (if not all) of the things you want to do can be done on Fresh. If it's lagging, wipe the caches using Amon and see if that speeds things up. I ran Fresh for a long while with no issues. For the past 3 days, I've been trying out the latest Baked Snack rom, and it's very good, too. The only thing I'm not sure about is the multi-touch feature because I haven't come across the need for it yet. I recommend you do the same thing I'm doing and everyone else does: Download them, flash them, keep them for a few days, and then try another rom. You'll be able to eliminate the ones you don't care for and then narrow down your choices. Do a search for multi-touch and see which roms have fixes for it, and try those out first.
or at least ava froyo v7, thats got everything working for me and use a kingsxkernel
I believe most of those are functional on most of the ROMs now. As far as swype keyboard, I think calkulins ROM (evio2) has that natively, or there's a new ROM someone else was working on that I think had swype listed, it was called echo5 ROM, I think. It's not on the first page, it was on the 2nd page last time I saw it.
The fps, overclocking, and >2pt multitouch are all functions of the kernel, I believe. And the 2 main kernel devs (kingx, and netarchy) support those functions in their kernels, which will flash on most any custom ROM
(I'm fairly new, from winmo, too. I was reluctant and apprehensive for awhile, but really starting to like Android, not to mention most the great devs from winmo are drifting to Android, or already have. Xda has made the transition that much easier)

Like stated, any Rom can be anything. You can flash almost any kernel with any ROM..You can start with the stock ROM and flash what you want to get what you want...very customizable compared to WinMo.
That being said, I'm running Calkulin's EViO and love it. I can get almost 10th hours with heavy, heavy usage. With multitouch visualizer from the market, I can see 4 touch points. The phone is overlooked and fast as veal...never laggy. 4G works just fine. Lastly, the latest version has sense as an add-on, so no worries about it starting.
And, I have swype as an .apk if u want it.
Sent from my PC36100 using XDA App
Thanks for the quick replies peoples, I went and wiped both cache, and the dalvik cache... even though I have no idea what the dalvik is, I'm using Anon Ra btw.
Calkulens Rom and a kings kernel sound like what I'm looking for, but what about the Bluetooth I know that sense based roms have corrupted Bluetooth settings, so no gamepad, are calkulins roms senseless? And work with wiimotes?
Sent from my HTC EVO
VaelPak is the greatest. Just doesn't support bluetooth controllers but may be in an update soon
Swyped from my VaelPaked Evo 4G
Um no you can't flash kernels on most roms. They are either for sense roms or asop (senseless roms..cm6) you have to read the kernel thread... and swype you can install on any rom just search and you will find out the apk. For it. 4g doesn't work on cm6 so that's out the question then...
Most kernels are set to 1.19 to 1.22 top overclock.. setcpu is a paid app to over/underclock.. battery life there are a lot of things that causes bad battery. Bad reception, screen brightness, a app that keeps your phone awake, the settings of your CPU...etc...

10hrs of heavy use? Please explain heavy heavy use because I get 4 tops even with the battery trick.. btw I use a wall charger not the phone. I have tried about every rom including yours and what I call heavy heavy usage is non-stop on phone. I can be on here on full battery, txt and do research on phone and get only 4 tops. Even with underclock.. you use wifi during heavy usage? Stock battery?
Just don't believe 10 hours heavy usage...

So that combination of Calkulin's Rom and King's kernel will not work?
And does Overclocking seriously affect battery life?

When you overclock your CPU is running faster than normal which in turn needs more juice... kind of goes hand in hand...
Yeah that should be fine. If I'm correct its a sense rom. When you look at a kernel you usually read what it has implemented and what your looking for in a kernel. They tell you which one its made for. Just was letting you know..
Also always do a nand backup in case of loops or anything goes wrong..

[Q] Rooted my Evo, got what I need on it, but now I want more!

So I successfully rooted my evo using the unrEVOked method here http://forum.xda-developers.com/showthread.php?t=787304 (I have hboot .97) I'm already using the free wifi tether (main reason for rooting) and I'm experimenting with setCPU. I also have Titanium Backup pro and have backed up all of my apps and whatnot. I want look look around for different roms and/or kernels. If anyone can make some suggestions, it'd be appreciated. I like the stock 2.2 layout, but if there's something that'll work better, can you point me in the right direction? Also, I'd like to be able to not have to find all of my apps again, and if possible, keep the app data too (i.e. I have shazam and would like to keep all of my tags). Also, if someone can point out the proper method for loading the roms/kernels, that'd be appreciated too!
go with fresh. . its by far the most stable and it doesnt prevent anything .. 4g flash, all sense stuff .. easily one of the more popular roms..

I am a huge fan of Avalaunch mods. AvaFroyo10 was just released, and I love it. He focuses on high quality multimedia. The audio is better than most other roms. He also has tweaked the APN so it will lock on to Verizon towers for 3G if Sprint has 1 bar or less.
i am also a giant fan of ava, but i am getting no battery power. as an experiment, i unplugged my phone with full power, no use, and it was fully drained in 7 hours. ava works on some phones but not others.

USB storage problem

Just flashed Decks 1.2 ROM along with Tiamat 2.1.5 kernel. for some reason when I connect the USB cord it only charges and will not allow me to use USB storage. Any ideas as to why not? It worked with CM7 and Warm 2.2 so there shouldn't be a reason for it not to work now.
Download the kernel manager app and try the godmode kernel it should work. If not try the savaged-zen cfs kernel and if it works but you don't like the idea of having SBC send me a pm and ill give you a link to a flashable zip that disables it
Sent from my PC36100 using XDA Premium App
Thanks for the info. It's going to have to wait until I home later tonight though. Apparently I can only download apps over wi-fi and not 3G. I'm hoping it's just a kernel issue because I'm loving this ROM.
Just flashed the Savaged-Zen kernel and now its working like a charm. You sir are a genius.
No problem like i said tell me if you don't want the SBC in the kernel because some people aren't comfortable using it thinking it will toast their battery...
Sent from my PC36100 using XDA Premium App
Brief description of SBC please? I don't know all that much about kernels. All I know is that it's supposed to help my battery life. It's been off the charger for 15 hours now and only down to 65% with me texting all day so I would say it's doing its job.
sbc will help you a lot with battery life it increases the batt life.
I use sbc with no problem. But 8 people have reported tht their battery has been fryed becuz of sbc (they have no proof but their word)
by the way decks rom with sz kernel sbc with viperboys scripts is amazin batt life
Ok thats another new one. What exactly are scripts? Forgive me for all the questions, I know how to root and flash ROMs but I never really got around to the nitty gritty until just recently.
Just google "kernel starter guide xda" that decribes everything you need to know (i also think its stickied in the development forum). And a script long story short is a line of code that when entered into the terminal emulator app will change how you phone does a certain thing(depends what that line was meant to do such as undervolting to save battery)
Sent from my PC36100 using XDA Premium App
I'll go check that out, thanks. Still having a problem downloading apps from the market over 3G though. I can download all day long over wi-fi with no problems so I dont get it. When I click install the download progress bar comes up and the icon appears in my notification bar but when it's done the app isn't installed.
Nevermind, I found the fix. Installed S2E and everything is all better.

[Q] Custom Kernel Request

Could anyone possibly add higher frequencies lets say up to 902? And most importantly, could someone also fix wifi on this kernel? I can almost guarantee that this would be the absolute best kernel available if all of this was done. http://forum.xda-developers.com/showthread.php?t=970543&page=68
The Kernel is Drowningkernel 8-9-1
Quick question: Would this work on the Slide?
Yes this already works on the slide. Just install thru clockworkmod recovery. its a very high performance kernel, the only problems are wifi and frequencies could be higher

I wonder. Setting such high frecuencies, wouldn't risk your cpu phone to get toasted???
Also, wouldn't it cause much more battery usage?

I'm running drowning kernel 7 and I'm stable at 902, and I get a few reboots at 921 mhz. And for battery life, the smartass governer takes care of that, my phone lasts all day.

I was wondering why is it that when ever i install a new kernel with cm7, I can't connect or mount my usb to my computer?
Hmm that's strange I don't think I've ever ran into a problem like that. Not sure if I can help much with that but what I would suggest is, do a completely clean install of cm7 and then install the kernel or you could start a thread in the q&a section and maybe someone with more knoledge than me on that problem could help.

Yeah, I've tried drowningchild's .35 kernel and it's very smooth. But wifi isn't working at all with it. I remember his previous kernels were fully functional. I wish someone could make that .35 kernel for CM7
Maybe someone could modify drowningchild's 2.6.35.x CM Aria kernel so wifi would work?

Galaxy S3 i747M Kernals?

I was wondering if there are any custom kernels out for the Canadian (rogers) Galaxy S3 SGH-i747m

no offense meant, but if you are asking this question I would advise holding off on flashing any kernels and get more comfortable with just flashing roms first -- Roms are more pre-packaged and you can build your comfort level by trying out a series of roms prior to messing with the kernel which is a more powerful and inherently more influential element to your phone's operation
Appreciate the input I have flashed many roms but i allways go back to stock, i flashed a kernal earlier but i went back to stock kernal because im scared of burning my processor, not quite sure how safe undervolting and overclocking is, and ya im a noob just got my first android phone about 2 months ago and just rooted it last month.

I haven't tried faux kernel but ktoonzes will be OK left stock processor wise, it won't burn out your processor. Plus you will benefit from his built in tweaks. As far as over clocking/ undervoting ( oc/uv) if you go too far your phone will either freeze up or reboot, so don't use any "set at boot" options until you know your phone will handle it. I use ktoonzes kernel with no oc just the lower frequencies and a mild under volt for battery savings with no ill effects.
thanks for seeing the comment in the way it was intended! seems you have going about things the right way: everyone's phone will accept OC differently, some operate fine at higher levels, others not -- Faux does not post "recommended" levels for this reason, asks that you make adjustments in small increments and use your phone to see how it handles the changes. It is very much a trial and error. I had an older S1 that was wonderfully resilient and would take any setting and still function -- I lost it long before it had a chance to get damaged, My own sense is the phone itself is robust and hard to actually kill -- my earlier caution was more to prevent you jumping in the deep end too soon.
I have tried both Faux and the KT747 kernels, presently running just stock which is in itself a pretty decent kernel.

I tried Ktoonz and it made my playstore act weird and not connect and error out and such.
So I reversed back to my backup image with the rom's initial kernel that was installed with it.
I only find Kernel's being useful for OC or Dual Booting if you need/want the fun with that.
Otherwise find an amazing rom like Serenity or WanamLite or something if you want more customizability
OR a stock rom whichever one suites you better.

Perhaps your voltages and/or settings were too much for your phone to handle. When it gets out of hands, apps will FC a lot and phone will usually freeze or reboot. If you didn't edit the settings, I don't think the kernel left at default settings would affect the Playstore's connection.
