Hi

Just sharing the rom for my daily use.

This is Bell Official V20f completly debloated and deodexed

Remove security error from ramdisk.

Kernel is overclockable and can be undervolt too.

Gpu is overclock from 266mhz to 300mhz for 3d and from 200mhz to 229mhz for 2d.

Add new governor = lazy, intellidemand, lagfree, badass.

Add init.d support.

Add Nova Launcher

Add 1% circle battery

Remove carrier from status bar

GitHub for this kernel

Can I flash this one on AT&T's nitro ?
[LG Nitro HD] HO!NO!:
yes AT&T and Bell can use the same Rom.
[LG Nitro HD] mpsantiago:
Is this much different from Liquid Nitro? Is the color theme the same as the ATT ROM?

ALSO... can you rip the firmware/baseband out of this and make it a flashable zip? :)
[LG Nitro HD] Technocian:
Tested battery life and it is comprable to Full Throttle.
[LG Nitro HD] abc001:
FC for LG keyboard. Am I alone?
[LG Nitro HD] mpsantiago:
I didn't have any keyboard problems.

For me the battery on this one was quite good. Maybe as good as Liquid Nitro... though I didn't test for long enough to know for sure.

Also, it isn't quite as ugly as AT&T's UI.
[LG Nitro HD] Technocian:
LG Keyboard and Stock keyboard I had no problems with, but they both sucks so I used Root Uninstaller to get rid of them both (frees up some RAM) and installed Swiftkey.

For anyone wondering, this is flashable via CWM. You DO NOT need to unbrick to install this ROM.
[LG Nitro HD] mpsantiago:
HO!NO!, a suggestion-

If you make another release of this ROM, can you swap out the included calendar for the one from the market? The one in the ROM does not have a widget!

Re: [ROM] HO!NO! P930 V20f mod

I just downloaded Google calendar. I also just wanted to give you props on this ROM. It runs beautifully, gives great benchmarks, and has great modifications made to it. My favorite ROM thus far. Keep up the great work!

Use this All out from V20f mod.zip

This is all the removed app so you can install them manually.
[LG Nitro HD] mpsantiago:
The status bar icons look sooooo much nicer in this ROM vs the ATT ROMs.

I modified my SystemUI.apk so that the status bar itself is solid black. The cyan icons pop nicely against it.

I'll be bouncing back and forth between this and CM10.1.

[LG Nitro HD] X0dus:
I have not flashed this yet, but are the settings to oc/uv in the init.d folder like your Full Throttle ROM or do we use System Tuner to set those values? Personally, and for what it matters, I prefer having the files in the init.d folder to mess w/ rather than that messy System Tuner app that never seems to stick values for me..

So can somebody clarify, how exactly can I reinstall apps from that provided zip? Thanks.
[LG Nitro HD] Swetnes:
Re: [ROM] HO!NO! P930 V20f mod

The easiest way is to use an app called x-plore available on the play store for free. Use it to push it to /system/app and from there set permissions.
[LG Nitro HD] JobNick:
You can use ADB or some file manger app such as Astro file manager.

If you having any trouble doing that PM me and I'll explain in detail.

Re: [ROM] HO!NO! P930 V20f mod

So... anybody want to post undervolting for dummies? lol
[LG Nitro HD] mpsantiago:
Probably the EASIEST way to do it is to download Kernel Tuner and have at it.

Just don't expect miraculous results and don't go nuts with it. You can more aggressively undervolt at lower frequencies but less so at higher frequencies. The CPU needs more power when it is under load and the CPU clock speed is ramped up.

Adjust in small increments, test, repeat. A good test I found is to make a phone call while wifi, bt & gps are on. That uses a lot of power and it'll reboot pretty quick if you've gone too low on the voltage.

In all honesty I see more noticeable results with a bit of underclocking. It seems that this device loses most of its power through the 3G/4G/Wifi radios and the IPS-LCD screen, none of which will be helped one bit by undervolting (unless you figure out a way to undervolt the radios and lcd!)
[LG Nitro HD] KrisPK:
with this rom some market applications are not compatible like Real racing 3 fifa 12 etc any way to fix that?

With p936 and cm roms those apps are compatible
[LG Nitro HD] Swetnes:
Re: [ROM] HO!NO! P930 V20f mod

Titanium backup has a restore market compatibility that van be applied to individual apps maybe this will help?
[LG Nitro HD] mpsantiago:
I wonder if it has something to do with the device identifiers in the build.prop file? Maybe you could compare a v20c build.prop with the v20f one?

I would assume that would work; just backup your data and all so you can do a clean flash if you run into problems.

What is the rom you got on your phone (working) before trying this rom?

Did you wipe data, cache, dalvik-cache?

Did you overclock your phone once? if yes, on which freq was it stable?

Did you undervolt your phone once? if yes, was it stable -25 mV on all freq?

Does the first release was working for you? Yes, aside from keyboard FC

Do you use cwm recovery? Yes

Where in the boot process does it stop? LG logo then black

Did you wipe data, cache, dalvik-cache? Yes

Did you overclock your phone once? if yes, on which freq was it stable? Yes it was stable at 17XXmhz. Didn't try higher.

Did you undervolt your phone once? if yes, was it stable -25 mV on all freq? Yes
[LG Nitro HD] Swetnes:
Re: [ROM] HO!NO! P930 V20f mod V1

1. With v1 I tried both CWM & TWRP, with v1.1 just TWRP.

2. Your original v20fmod works perfectly (using now).

3. V1 I could get to boot once if flashed over v20fmod original, only after wiping data but after 1st reboot would boot loop at after capacitive buttons light.

4. V1.1 I almost got to boot by installing dirty flashing v20fmod but rebooted after apps rebuilt when phone said starting apps. Would only boot loop after full wipe.

5. Overclocking - sometimes but don't like to phone seems to run hot. 6. Undervolting - never had luck.

7. Don't know if this helps but wind kernel works fine on my phone but don't use.

8. And yes all caches were wiped.

Re: [ROM] HO!NO! P930 V20f mod V1

I just spent quite a bit of time trying to get it to boot with no luck...infinite bootloop. I tried dirty flash over your previous version, after full wipe/format, flashing package repeatedly. Still bootloop after lg logo. My phone is stable at oc up to 1836, and was oc'ed as such using the previous release. I did not undevolt but have on different roms stable up to -50mv on some frequencies. Phone has been unbricked. Feel like I'm forgeting some info so if there's anything else u need just lemme know. Thanks again for your contributions
[LG Nitro HD] HO!NO!:
In try number 2 i return to stock value for overclock and voltage to narrow down the problem of why i am the only one able to flash it... :confused:
[LG Nitro HD] mpsantiago:
Can you post MD5 checksum?
[LG Nitro HD] keenz:
Well... Tried a few times. Just boot loops.

I'm using cwm and have had my phone at stock settings.

Came from v20f mod which runs perfect minus the lg keyboard fc.
[LG Nitro HD] Swetnes:
Re: [ROM] HO!NO! P930 V20f mod V1

Well I didn't get a boot loop this time... It just causes my phone to power OFF and this happens after the capacitive buttons light. I know this because I got the power off charging graphics... Very odd, HONO each version seems to be getting worse for me anyway.. The best so far (not including orig) has been v1.0, I could at least get it to boot once. I am still using TWRP, let me see if I get any different results with CWM.

[LG Nitro HD] Swetnes:
Re: [ROM] HO!NO! P930 V20f mod V1

Ok I got v1.1 try 2 to work once, would reboot and everything. In an attempt to duplicate what I did so I could pass it on to everyone I cannot get it to work now :(. Just in case someone else wants to try I did the following:

1. Dirty flash v1.1 try 2 along with wind kernel using Rom Manager.

2. After phone boots open Rom Manager again and reflash v1.1 try 2 and reboot.

This worked the very first time I tried it but hasn't since so maybe it was dumb luck. I confirmed this by the fact that kernel was v3.08-perf and software was mod 1.1.
[LG Nitro HD] truonglv:

this rom is badass with wind 3.7, also check nitroTNT, it's basically the same except with a differant look. had to bump this to show respect to Ho!No! for his great work even though he has departed from us. this rom is still extremely relevant it's now my main rom as it supports 1080p recording, MHL (microusb -> HDMI) 1080p and with wind 3.7 it is very snappy fast, you can even turn on the experimental intellidemand settings but they can be unstable, using default settings i have 100% stability over first 3 days on this rom and swetnes's version of this rom (tried them both) swetnes has better default keyboard but i like the status icons on this one better, so it's a prefference thing, swetnes said he might work on the statusui and i few other things so with some developement his might be better, right now i just wanna bump this so people don't forget it exists, Ho!No! worked hard on this i'm sure.

[LG Nitro HD] KronicSkillz:
Kronic BlueMod V 4.3

for bell based v20f, also works on most other v20f but some icons may need to be swapped.

- to backup original ui, make a copy of this zip, open the copy with 7-zip, replace /system/app/systemui.apk and /system/framework/framework-res.apk with the CURRENT ones from your phone (adb pull them or something) then rename the copied zip originalUI.zip and put it on your sdcard, in case something goes wrong you can reflash it to go back to default.

- to install just flash the zip in recovery mode, do not wipe cache partitions.

enjoy!!!!

carrier from status bar

everything is ok.. just i would like to restore the carrier name from status bar...

How can i do that¿?
[LG Nitro HD] KronicSkillz:
not easily, it's done through editing the xml of SystemUI.apk/res/layout/status_bar.xml

you have to add a reference to the smali code that adds it in the layout.

i would give you the code but i don't run any rom's that use it so i don't have it handy, you can find it with a simple google search though, most people remove it so search for "how to remove carrier label from status bar" and read the tutorials, then when you find them quote, remove the line that looks something like this.

<com.android.xxxxxx.carrierlabel android:textColor="xxxxxxx" android:xxxxx="xxxx" >

copy and paste that line and add it to your status_bar.xml where they say to remove it.
