[Epic 4G Q&A, Help & Troubleshooting] sdpluth:
Ok. I apologize upfront if I have missed the obvious but I have searched the

forums and have gotten lost in the details (responses are to specific

phones, methods of rooting, Roms etc.) and I am not sure what would apply to

my situation without asking.

Thank you for your patience!

First here is my configuration as best as I can describe:

Sprint Samsung E4GT, I rooted basically so I make backups with Titanium. I

was able to use clockworkmod and rom manager but I really do not understand

exactly how to use them fully.

I did not install any ROMS and I am still on EL29. Gemini App Manager shows

very little RAM (248MB) and internal (171MB) space available but I have

plenty on USB storage (4GB) and on external SD (4GB).

I am having problems with installing apps because device memory is low (and

this is after transferring my largest apps to external SD and deleting all

cache and application data). I only put 45 of my largest apps on external SD

because if I go over the 50 app limit it sends my phone into endless

reboots.

I saw this thread

(http://xdaforums.com/showthread.php?t=1680844&highlight=battery+

script) about using blazer but I am really not interested in putting any

ROMs on my phone and want to maintain full phone capabilities (wifi, gps

etc.).

However, I would like to remove bloat and improve battery life.

My questions are as follows:

1.) Can I use Calkulin's Bare ROM Converter

(http://www.androidauthority.com/galaxy-s2-epic-4g-touch-bare-rom-converter-

68213/) with my configuration (i.e. EL29 without putting a ROM on). The

article seems to state that you just need CWM but in the thread it links to

everyone is talking about ICS.

1. part 2) The article states that it saves the files to the SD card but in

the thread several people report that it actually doesn't.

1. part 3) how do I restore specific files if needed. Will Titanium be able

to restore a specific bloatware file?

2.) I saw this post on improving battery life for the E4GT

(http://xdaforums.com/showthread.php?t=1527041&highlight=el29&pag

e=472) but it seems to be specific to the FF22 ROM. Is there something

similar for EL29?

2. part2) is a 'script' like this ROM independent or can it be modified for

EL29?

I realize that I am kicking it old school in wanting to stay with EL29 but I

just want to keep things simple until I have a better understanding of what

I am doing.

Thank you in advance for any thoughts or suggestions!!!

This is the list of apps that I have installed on my HTC V

There are some apps which I have never tried... But yes, all of them are working on this phone without any performance issues.
[HTC One V] paarthdesai:
which are your favourites? the best ones?

dont just say thanks hit thanks if i helped :)
[HTC One V] 1ceb0x:
Dude, you have so many apps that are only for camera and editing photos. Why don't you use only one that does both? Instagram is a good choice.

A good app is Airdroid, I think that's why is in your top of the list :). Another indispensable app is "AdFree" which makes your phone to not display ads of any type in any application.

Root explorer should be a good choice for advanced users, Nova/Apex launcher, Terminal emulator (for when you need to do something and you don't have adb at your hand).
[HTC One V] iamsonal:
Yeah, I do think so. Need to remove some of the photo editing apps.

No its because if u rearrange all the apps in alphabetical order, AirDroid will come at top... :p :p :p

AdFree needs a rooted phone... Right now I am happy without rooting it.

1. Total Commander - Best file explorer... far better than ES File Explorer too...

2. DICE Player - Best Video player for HTC... Infact it plays mkv files without any problems

3. Juicedefender - Battery Saver, reducing power usage. Battery lasts for a longer time.

4. Sygic - Voice Navigation and offline maps

5. Pixlr-o-Matic - Best photo edit software... I think its better than Instagram

6. Wordweb - Offline Dictionary... cant live without it

[Samsung Galaxy Nexus] ÜBER™:
That will definetly come in good use. Thanks :)
[Samsung Galaxy Nexus] pastert33:
This is nice! Thanks! One thing that I thought would be useful is to have a notification pull down toggle for NFC. so you think that's possible?
[Samsung Galaxy Nexus] FrostyF7:
This is handy thanks dog lol.

Sent from my Galaxy Nexus
[Samsung Galaxy Nexus] obsanity:
Hmmm... I've always been able to use Google wallet with the screen off. I'm not sure about any other nfc use though.
[Samsung Galaxy Nexus] BK553:
Awesome man, thanks. Just bought some NFC stickers to mess around with and this was my biggest problem. Really appreciate it.
[Samsung Galaxy Nexus] BeerChameleon:
Nice!! So the screen of one is only if the screen is off without a lockscreen? :confused:
[Samsung Galaxy Nexus] Geniusdog254:
No. Sorry, I'll update the OP to be a little more clear.

Screen off means you can ALWAYS scan an NFC tag. Don't have to turn the screen on or anything. Just touch the phone to the tag.

The lockscreen version lets you scan a tag whenever the screen is on, but it doesn't have to be unlocked. You can't scan while the screen is off, but you can just touch the power button to get to the lockscreen and then scan. If you have a passcode, no need to unlock your phone to scan a tag.

It's definitely possible. I'm working on getting the option in Settings now, and should have it working by the end of the day. Once there's an option in Settings, it should be super simple to add a notification bar toggle option as well. Haven't messed with that part before, but it's not too dissimilar from WiFi toggling, so I've got code to look at.

I was hoping to get the settings mod done in time to submit it to CM before they started the code freeze for CM9. Well, they went into code freeze this morning so I missed that. I'll still get it submitted ASAP, but don't expect to see it in the initial CM9 official build unless you use the nightlies. I'll of course update everything once I submit the patch and if it gets accepted.
[Samsung Galaxy Nexus] BeerChameleon:
Darn it LOL i would love to have one that works with both :D

Great work tho, i will probaly get the lockscreen one :D
[Samsung Galaxy Nexus] agentdr8:
Any thoughts as to if this will work on the One X? I'm backing up my stock NFC.apk anyhow and am going to test it, but I thought I'd ask in advance.
[Samsung Galaxy Nexus] Geniusdog254:
In theory, it should work on any 4.0.4 base ROM, on any NFC device. No guarantees though
[Samsung Galaxy Nexus] Rumble6059:
This is just what I've been looking for (FOR AGES) I know that it doesn't come like this from stock, due to the potential security risks, but sod it! Lol, i love it.

Thanks for the fantastic work :-)

[Samsung Galaxy Nexus] zcmack:
im curious as to the effect on battery life. how noticeable is the difference?
[Samsung Galaxy Nexus] Smurph82:
I think that this is a great feature. But I thought that the reason

the NFC only worked with the screen on and phone unlocked was

a security reason. Meaning someone could not just walk up to

you and scan your phone without you knowing. you would have to

have the phone on for anything to work. I think that the settings

idea is great that way if you want to open then you can have it open

if you want it closed then you can keep it like stock. Great work. Worked

good on my GNexus (Sprint).
[Samsung Galaxy Nexus] Geniusdog254:
I can't speak for the battery life, as my phone is plugged in either for tethering or testing code all day. Shouldn't be too noticeable.

Security is exactly the reason it doesn't come like this by default. It's also why I made two versions. If you're worried about security, then flash the lockscreen version and you have to turn the phone on to be able to scan.

Currently, there is no way that I know of to get anything malicious by scanning against someone's will. It doesn't just offer up credit card numbers when you scan it. If you have NFC Task manager on your phone, someone could scan it and make it start an app you have installed or turn off wifi or something mundane like that, but that's about it. Plus they'd have to get within ~5" of your pocket ;)
[Samsung Galaxy Nexus] agentdr8:
It would appear that the One X's Nfc.apk has different hardware support. When I flashed your zip, NFC ReTag couldn't detect NFC hardware any more. And the option for NFC disappeared in Settings. Nothing a restore of the original apk couldn't fix, but it's unfortunate it didn't work.

Any chance you'd be willing to share what edits you made? If it's smali, I can probably tweak the One X's apk to be similar.
[Samsung Galaxy Nexus] Geniusdog254:
It's actually compiled from source. I've never messed with Smali, so I don't know how useful this will be. The easiest way is to tweak a variable called POLLING_MODE in the NfcService class. There are a couple different settings. 3 is the default, 2 works on lockscreen or unlocked, and 1 works with the screen off, at the lockscreen, or unlocked.

I don't think Smali keeps variable or function names, so that might be of no use at all.. The other method, in a function called applyRouting() there are a couple if/else statements that check if the current state matches POLLING_MODE or not. If you take those out, then it should also work although for some reason that only seems to enable it to the lockscreen level.

You should be able to see a copy of the file here, if that helps.
[Samsung Galaxy Nexus] Smurph82:
I did not mean anything by my comment, I think that having to turn the phone

on to use it is a bit much. I like that you have the ability to run it form the lock

screen. I understand that right now you really cannot do much with the NFC,

hacker wise, other than changing settings you are not stealing information by

scanning. But being that NFC is still new(ish) I also feel that all the security

holes have not been discovered. I just wanted people to consider every angle.

I still think that you have created a great feature.
[Samsung Galaxy Nexus] Steady Hawkin:
I love what I'm seeing here, well done! Can anyone confirm if this breaks Google Wallet functionality?
[Samsung Galaxy Nexus] brium13:
One idea please ?
[Samsung Galaxy Nexus] G405T:
I tried applying the usual changes to NfcNci.apk and they didn't have any effect :/ Something more involved is needed..

Anyway, I suggest you move that question over to the Nexus 4 forum now, to show your interest where developers will be more inclined to help.

(and before people start telling you off :p)
[Samsung Galaxy Nexus] XlAfbk:
I provided a diff file for CM10 in http://xdaforums.com/showpost.php?p=29625900&postcount=93

You'll have to put use that diff to go through the 4.2 NfcService.smali and make all the changes listed in it manually (as the ids will have changed).
[Samsung Galaxy Nexus] brium13:
Thank for repli

Merci pour votre réponse
[Samsung Galaxy Nexus] je55ter:
I just got done re-applying the diff for my GSM GNex. This was made from the nfc files from stock 4.2.1, though it will probably work for 4.2 as well. It will NOT work on a Nexus 10 (I tried). Supposedly, the N10 has two nfc chips, which is probably why it uses a different apk (NfcNci.apk) for nfc. Not sure if this will work on other Nexus devices like the Nexus 4.
[Samsung Galaxy Nexus] brium13:
Hello, Nexus 4 use NfcNci.apk :(
[Samsung Galaxy Nexus] bulgareli:
This dosen't work on my GSM GNex with paranoidandroid 2.99 (4.2.1)... had to flash the ROM again...

It is possible that will only work on stock ROMs?
[Samsung Galaxy Nexus] je55ter:
Probably.
[Samsung Galaxy Nexus] nerys71:
no this will work on any rom that use PRECISELY the same nfc.apk

SO if you can get someone to modify the nfc.apk that comes with your rom it should work fine. Stock or not should not matter.
[Samsung Galaxy Nexus] Ragnarok:
hello,

works with DLJ4 version ??:confused::confused:
[Samsung Galaxy Nexus] daniel_loft:
Geniusdog254, is there any change that you could look into eliminating the annoying sound that Nfc.apk makes whenever it reads a tag? Or maybe changing it with something less loud or just with a vibration.

Thanks!
[Samsung Galaxy Nexus] nerys71:
I love the sound its confirmation it worked :)

changing it should be as easy as finding the ogg file that is that sound and changing the file to anything you want (even a blank file so it makes no sound)

I will try to figure out what the sound file is later tonight (just play a bunch till I hear it or see if a file name stands out as me me me :)
[Samsung Galaxy Nexus] XlAfbk:
the .ogg is in Nfc.apk. You can easily replace it with a silent one yourself.
[Samsung Galaxy Nexus] bombadier:
I have attached the two NFC app files from the 4.2 ROM I am using,if any of you wizards could have a look and do the patches to get it working screen off It would be much appreciated,

Thanks in advance
[Samsung Galaxy Nexus] daniel_loft:
XlAfbk, I've decompiled Nfc.apk with elesbb's GUI APK Tool v1.1.4.5, edited the ogg's with Audacity (just applied a reverse effect), recompiled the apk, put it on the phone with adb (while in recovery), fixed the permissions and rebooted the phone. Now there's no NFC functionality (not even the NFC settings). I've also signed Nfc.apk after compiling with no better result.

What am I doing wrong? Do the size of the ogg's matter?

Thanks!

PS: Sorry for kinda hijacking this thread.
[Samsung Galaxy Nexus] XlAfbk:
don't decompile, just replace the ogg files. the apk is really just a zip file (with some extra stuff)
[Samsung Galaxy Nexus] daniel_loft:
I just replaced one of the ogg's (opened the apk with WinRAR, replaced end.ogg and pushed the apk to the phone) and now the Nfc Service keeps on crashing.

What am I doing wrong?

They are zips, but they're signed, which is likely why you're seeing the crashes. You need to resign the apk before pushing.

[Samsung Galaxy Nexus] XlAfbk:
the instructions on how to change Nfc.apk yourself are already in this thread.

Tutorials for creating recovery zips can be found all over the web. Easiest way is to just grab a working recovery, remove its files, put in this one and edit the recovery-scripts

EDIT: Had a minute to quickly do it while the GF was getting ready. Here you go. Only for phones/tablets with Nfc.apk, not for those with NfcNci.apk!

Has anyone gotten this working on the Note 2?

I know the screen off possibilities of the Note 2 are much different than the original Note. I quite a few things working with screen off on my original Note, but have been unsuccessful with the Note 2. Even Sleep as Android will not track the sensors if the screen goes off. So I'm guessing there's an additional layer of coding that disables these that makes it not possible?

Any success? I'm on AT&T if that matters, but the device seems pretty streamlined across carriers.
