Just wondering, why is this mod usually included in these ROMs?
Disabled search button(Enable zip attached)
What is the benefit? I know that I and many others take advantage of the re-enable zip because I like the ability to search any searchable window. Are accidental key-presses a problem? Do you assign it to something else?

Started using this ROM this morning, probably about 5 minutes after he posted it, lol. I have to say its great. Not sure if it really matters to anyone, but Im a fan of the eVdO thing instead of 3g. I was glad to see it in there. Even the internet icon in the dock..

It is also silky smooth. Normally I theme roms, but this one i like just the way it is. I just used the desire flip clock and left it be from there. I love it. no issues with anything, even seem to have a little better reception :)

But yes, overall its worth the flash, or the upgrade if ur already using the previous rom version.

I live in Durham NC and have always had 4g but i dont get the speeds people are showing on 3g or 4g. I have never made it above 1.5 meg. Is there another wimax zip to use. If i connect 4g, i get connected and i have a really strong signal, but never above 1.5. Please help.

Sent from my PC36100 using XDA App

I work in Durham. Just ran test speedtest.net app to server in Wichita, KS. Download 4001 and Upload 990.

3g speeds are terrible in this area for me. Still using 1.34 and only updated my radio to the latest version. I haven't updated the other components because my phone isn't s-off.

Downloading now. Calk, do you use Sense or the ADW launcher? Care to post your homescreen if you use the launcher?


I have both setup but I use Sense more often because of the widgets. If I ever find a hack to use the Sense widgets on ADW or replacement widgets, I would dump the Sense launcher in a heartbeat because I like to have 5x4 icons on this big of a phone, plus the option of customizing the launcher is a big advantage.

As for my setup on ADW, I just have Beautiful clock/weather widget on a 1x4 on top and the rest 4x4 are icons

when you downgrade the PRI do you recommend having the matching NV too or is it ok to have 1.71NV with 1.34PRI?

I'm currently using NV 1.71 but so try with that one or downgrade if you want to test the older ones

Why do a Nexus One port?? Why not a Lexikon port?? Just wondering.

FRG83 is the Froyo base, the Lexikon only has the updated Sense, it still has FRF91 as the base

Accidental hitting is the main purpose of the mod because with this big of a phone, I found myself hitting that key almost everytime I used the phone for more than a couple of minutes

As always it looks nice and clean. However, I seem to have a problem in downloading from market, has anyone else tried?
or, is this just another day when the market server is screwed up?

try running the fix_permissions script that's included with rom manager... then reboot and try again.
let me know if it helped.

Just load this to my evo and I am getting the error message:

"The application Internet (process com.android.browser) has stopped unexpectedly. Please try again."

Any idea how to fix it?

1.4 is working great so far

It wont let me install the stock app from the sd card

What app because some require you to use ADB or root explorer to install as they won't install using a file explorer.

Just load this to my evo and I am getting the error message:

"The application Internet (process com.android.browser) has stopped unexpectedly. Please try again."

Any idea how to fix it?

Try clearing data for that app in manage applications to see if that helps

    EViO 2 Series



    Based on rooted 2.2 / FRF91 - 3.70.651.1

    ROM includes:
    HTC #15 kernel(undervolted)
    Most HTC apps
    ADW Launcher
    EStrongs File Explorer
    HTC_IME mod
    Wireless Tether
    and a couple more
    (Removed apps are in the sdcard/Removed_Apps folder)

    MODs included:
    Tweaked system(Very FAST)
    Unlocked 3G USB tethering & Sprint Hotspot!
    Moved dalvik-cache to cache partition
    Reduced auto-brightness range for better battery life
    Disabled search button(Enable zip attached)
    Removed haptic feedback from dialer & stock Android lockscreen(if you decide to use it)
    Notification bar will display TRUE network speeds(2G(1x) when used), instead of always 3G(EVDO)
    Battery % on battery meter(ported from Smooth Icons)
    Removed USB Debug notification
    Removed purple hue from most of Sense
    Colored notification icons
    Rosie app launcher displays 5x5 icons & swapped right button to launch the browser(ported from JsChiSurf's Rosie mods)
    SNQ's 4-in-1 Reboot option mod
    JsChiSurf's Notification Menu Power Widget mod w/ custom icons
    Upped MMS size limit to 5MB(Default is 2MB still)
    Modded Flash Player so Hulu works
    Annoying ads in programs are blocked

    System has also been de-odex'd, apk's have been optimized & aligned

    Notes about Battery Saver script

    Can be used with HTC or custom kernels
    It completely eliminates the need for SetCPU or Overclock Widget
    Easily customizable if you use a text editor(scripts located in /system/etc/init.d)
    It will set Max/Min CPU speed to 245MHz(384MHz if a VDD kernel) and governor to powersave(if available) when a sleep
    If SetCPU or Overclock Widget are detected, the script is ignored, so it will not affect them
    Preset profiles are:
    1.075GHz(custom kernels only) - 100-90%
    998MHz(921MHz for VDD kernel) - 89-51%
    844MHz(uses -50mV less) - 50-16%
    768MHz(uses -100mV less) - 15-0%

    Script is specially tuned for kernels that can set VDD levels(Ziggy471's recent are the only ones that I'm aware that can do this), so you will get the best battery life from those kernels

    If you want the best battery life from a VDD kernel and your phone can handle ultra low voltages, try the -100mV or -150mV zips in the FAQ section

    Using now HTC's #15 kernel(undervolted)
    Battery saver script now includes profiles to save battery when battery levels reach preset levels
    Tweaked voltages for VDD kernels
    Kernel now includes support for Apps2SD
    Unlocked hidden phone settings
    Cleaned up build.prop

    Reduced undervolt to -50mV to help those PICKY phones that don't undervolt well
    Created a -100mV for those phones that can handle -50mV but not the -150mV undervolt
    Made notification bar display TRUE network speeds[SIZE="1"](2G(1x) when used)[/SIZE], instead of always 3G[SIZE="1"](EVDO)[/SIZE]

    Ported JsChiSurf's Notification Menu Power Widget mod w/ custom icons
    Created custom CPU scaling script that eliminates the need for SetCPU for HTC & custom kernels[SIZE="1"](unless you want multiple profiles)[/SIZE]
    It will set the powersave governor[SIZE="1"](or leave default governor if not available)[/SIZE] and set Max/Min CPU speed to 245MHz[SIZE="1"](128MHz if available)[/SIZE] in sleep mode and switch back to default governor when awake
    If SetCPU is detected, the script is ignored, so it will not affect it if you want to use it.
    Also if the kernel can set VDD levels[SIZE="1"](Ziggy's latest is the only one that I'm aware that can do this)[/SIZE], it has a special script and voltages for those kernels

    I have my twin nephew's birthday to go to this morning, so I'll post v1.7 based on 3.70 a little early and do the change log this afternoon when I come back. And before anyone ask, yes you can update from my current builds but like always, wiping is always the best option especially when new framework/apk's are included.

    EViO 2 ROM (v1.7)
    The EViO 2 ROMs are definitely my favorite out there but I would love a flashable zip for the non-transparent taskbar as well!

    here you go...
    this is the power control (with smooth icons) flashable zip. NAND backup first:D. This will make your taskbar black again and add the power control widgets we all like and love. the only thing is the curtain will be back to white (you will see) and it will also revert the taskbar icons to default (not the notifications). some animations are also altered.
    I just tested it on 1.7 and works well. hope that helps.
    EDIT: attached my version of widget.txt to add 4g to the power control. here my order:

    EDIT 2: added the power control flashable zip attached to the post.:D

    EDIT 3: ORIGINAL THREAD: http://forum.xda-developers.com/showthread.php?t=877003
    Well, instead of sleeping last night, I stayed up and got v1.7 based on 3.70 done, so I'm doing the final testing of it now. Should have it posted before the weekend is up or Monday at the latest
