[Galaxy S 4 i9500 Android Development] cmd512:
Last thing you need to do is apologize for anything, Uncharted is the fastest freaking ROM out there when it comes to release!

[Galaxy S 4 i9500 Android Development] bombaybadboy:
I always recommend a clean flash then no chance for complaints and makes my life easy but so far no problems with a dirty flash.

91% but i got to 100 earlier and just froze on AFH :(
[Galaxy S 4 i9500 Android Development] cmd512:
I used to as well... with my S1, S2, and S3. I just think Samsung as come a long way with ROMs, especially the way partial updates are pushed out now. Like I mentioned, I dirty flashed all the way until KitKat (ha) with no issues. For KitKat, dirty flash just fell flat on it's face, so a clean install was indeed required.

Nothing else to tell you but ,thank you BBB , to tell you the truth am the same as you

I downloaded the ROM , that was fast :)
[Galaxy S 4 i9500 Android Development] scarookie:
Man, you guys are fast. Wasn't it less than a week ago that you released uncharted v5 XXUGNH2. I can't even keep up with the pace of these releases as v4 still feels very new on my phone, and I'm afraid to dirty flash.

Then if I may ask, what is the relevance of a CHANGELIST and how is it interpreted.
[Galaxy S 4 i9500 Android Development] bombaybadboy:
Samsung only tell you the change number not list. On the S2 we use to have a member that would check and find all changes but no one does that for the S4 that i have seen. So all i can tell you is its newer and has more changes than the last fw

Hi. This is a fantastic rom, very fast and with great battery life. Happy I have found it.

As for the network meter in status bar, how do I enable it? Do I need to install an addon for it? All I see is the addon for removing it.
[Galaxy S 4 i9500 Android Development] sco1984:
Hello,

I am going to try out this rom today for 1st time. 1 doubt before flashing = I am facing issue to read contents on micro sd card via stock rom 4.4.2. [when using Sygic it can't read maps when copied to external memory card. says access denied.If I copy maps in internal mem it reads :( ]That security parameter is removed in this patch? And I hope flash is working for camera in this rom.

Thanks & Regards,

Amey.
[Galaxy S 4 i9500 Android Development] Siberian Tiger:
You can use an xposed module to enable it ☺

The fix for sd card is already included in the rom ?

Moderating via Galaxy
[Galaxy S 4 i9500 Android Development] dbenyakar:
Yes but that I can do with any rom. I presume the feature listed as supported by the rom does not refer to xposed.

The fact that it has a mod to remove it means this is a rom built in feature.

[Galaxy S 4 i9500 Android Development] bombaybadboy:
the reason Newer Versions doesnt have network meter is i didnt build the original mod it was given to us by engloa. i just read up and built a new one for you and added it to flashlight toggle and smali % battery V6-Flashlight toggle-smali battery-network meter

Also yes i will build a lite v6 version and i will try to add a mega mirror but there has been problems with my internet

Thought you included that mod in newer builds, that's why I didn't bother to update that mod
[Galaxy S 4 i9500 Android Development] bombaybadboy:
Thanks for the reply m8, a lot of the mods built here are SystemUI mods and i didnt no which ones to add network meter to. :)
[Galaxy S 4 i9500 Android Development] engloa:
Not much changes from JB. You put the smali files in com/android/systemui/statusbar/policy for network meter, battery bar,clock mods and so on..and declare/call them inside status_bar.xml(instead of tw_status_bar.xml)

Wiima Theme

hey mates

I've been trying to install Wiima theme on this rom but I've done successfully only if I don't install any theme like 3Minit or flashlight toggle. If I install any of these Mods my status bar disappears and it is impossible to work.

I also tried to do 3Minit Mod decompiling and compiling my SystemUI with Wimma theme and although 3MinitMode worked very well, every time I received or made a call SystemUI forced close and did not respond until it reboots itself.

Can you help me please with any suggestions to get working Wimma theme in this rom? The Rom is great but I still missing Wiima Theme.

Hey guys & Gals.

I been running v4 for over a week now.

All is great, another fantastic ROM.

Two things though,

Quite often when opening browser (stock) i get a blank black page.

Also, i cannot install any apps that aren't from PlayStore. Its set up to allow them in security but they just won't work.

The "install" button just won't do anything.

Any advice?

[Galaxy S 4 i9500 Android Development] bobdoblo:

[Galaxy S 4 i9500 Android Development] bombaybadboy:
Did you dirty flash m8 and is that v4 lite? I suffered with the google playstore bug for 5 days and needed to install facebook, twitter ect from other sources and never had any trouble. Browser may be poor signal, Maybe its time you moved to V6 m8 and see if you still have these problems.

Sent from my GT-I9500
[Galaxy S 4 i9500 Android Development] gp545:
No, it's not for browser. That's the solution for not able to install apps.

Read some thread on XDA and I try to write down whatever I remember!

Setting black pixels turns off pixels on AMOLED screen.. Because of that down most pixels towards home button becomes unresponsive. This makes Install and Cancel options untouchable. Disable screen filter and you're good to go.
