[Sprint HTC EVO 4G LTE] Magnum_Enforcer:
Yes, if you use the tool it will revert your phone to S-on.

As far as whether or not Sprint or HTC cares is almost anybody's guess. I've seen people say they don't care, and others say that they do. Just to be safe go back completely stock. You can always root it again once you get it back:cool:
[Sprint HTC EVO 4G LTE] jocarog:
Yes it will take the s-off flag to s-on, you will be back to stock, updated to 3.16, after that if it gets fixed/repaired you should be able to get s-off with moonshine / facepalm / dirty racun whichever it's easier for you...
[Sprint HTC EVO 4G LTE] KB3NRY:
Thank you both very much! This sounds like exactly what I was looking for. I'll give it a shot and see if I'm still having the issues I'm having. If I am, I'll send it back. We send my wife's phone back to HTC once (never rooted) and they were pretty easy to work with. Just cost us about $8 in shipping or something like that.

I am honest with Sprint employees about my phone being rooted whenever I have an issue. They never seem to mind, they just can't always be as certain if the problem is their problem or something from me messing with it...and I understand that. I usually test with my wife's phone and see if I have the same problem or not. Anyway, for what it's worth, Sprint has always been good to me as far as my phone being rooted, but I wasn't asking for warranty work at those times.
[Galaxy S II General] Gutslit:
One of the most popular practices amongst software developers is to leave ‘backdoors’ within the code, which essentially allow anyone with knowledge to get into the system at a much deeper level than you’d expect from an end-user. These backdoors aren’t always with a malicious intent; most of the time, they allow the OEM or programmer to get into the system for troubleshooting when other, usual modes of access have been blocked. They can be quite friendly and helpful if you know what you’re doing.

Smartphones have a good share of these as well, where they’re generally known as secret codes. Most of the time, these numeric/symbolic sequences allow you to access hidden menus, diagnostic tests, areas that could change some of the most basic parameters of your device and whatnot. These secret codes, in fact, have not been exclusive to smartphones, but have long been a part of the dumb-phones and then the feature-phones before most major OEMs joined the smartphone bandwagon. For those devices that run Android, certain codes are shared across the board, and hence, can be used on a variety of devices.

What follows is a collection of some of the secret codes common to the Android platform. All of these would be entered through the phone dialer (just punch in the sequence as shown). Since most hidden menus are manufacturer specific, there’s no guarantee that they’ll work across all Android smartphones, but you can try them out nevertheless on your Samsung, HTC, Motorola, Sony and other devices. Be advised, though, that some of these can cause serious changes to your device’s configuration, so don’t play with something that you don’t fully understand.

Actually, some still work, but our phone uses the old format instead of the new. So don't type "*#*#1234#*#*", but "*#1234#". Same for service mode: "*#197328640#". Etc. Also interesting: "*#9900#" for "SysDump" and fast dormancy.

[T-Mobile Samsung Galaxy S II SGH-T989] grantusmantus:
Im new to this device and have been reading through the dev forums and notice that everyone uses different recoveries. Does it matter really wich one you use? I like twrp but I had problems with it when I had my g2x. Is there a deffinitave answer as to wich one works best on this device? (CWM or TWRP) I know that this is mostly based on user preference but it seems that some custom roms will only install on a specific recovery.

Thanks in advance.

Sent from my SGH-T989
[T-Mobile Samsung Galaxy S II SGH-T989] krazierokz:
personally everyone has there own opinion i use CWM on my vibrant & GS2 but i use TWRP on my nexus s and nexus 7 not sure what my mytouch uses but CWM for always will and always has worked well without any bugs or hiccups that TWRP sometimes has but TWRP is very simple and straight forward its all on whats your preference though if you are going to use TWRP the latest is 2.6 and you should not flash it through GOO manager use the odin file when you get there
[T-Mobile Samsung Galaxy S II SGH-T989] soupysoup:
TWRP is by far a better way to go, not that CWM is a bad recovery, its just not updated frequently, and with the new scripts flashing jb roms sometimes things don't always work right, I've used both and I think twrp is a better choice, I've never had an issue with it like I have on cwm, plus with twrp u won't need superwipe scripts or anything like that anymore, overall I think its a more complete recovery
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] vigilante.zen:
Let me start off by saying thanks everyone~ I am absolutely addicted to this site..... (dont know if thats good or bad):p

1) In the Google Edition rom does anyone know if there is a "dock" mode. In the TW roms there you navigate to my device>accessory> Then you have audio output mode. This enables me to listen to my music in the car utilizing the ibolt car dock.

2) Any suggestions on a lockscreen widget or conversion to TW rom that acts like the AOSP roms lockscreen? I like to unlock to phone feature from lockscreen.

General statement I am currently using Goldeneye rom and found that if you flash the ausdim v4 kernel it improves benchmark results drastically. Phone seems to be little snappier. May be a figment of my imagination.... maybe it is..... Just wanted to see if anyone else had tried such and had similar results.

thanks again everyone

[Motorola Atrix HD] Blackest Pain:
Hey guys I've been flashing and rooting and unlocking for a couple years and I'd like to actually learn how to build roms, apps, ect. Where can I learn?
[Motorola Atrix HD] frog1982:
I think the best place to start learning how to develop apps is the official android SDK with adt. but if building android is what you want then take any Linux distro and start reading about official aosp. information for both are publicly available from Google.
[Motorola Atrix HD] Blackest Pain:
Linux is, like, mac or something right? I'm on Windows 7 so am I screwed?
[Motorola Atrix HD] matt99017d:
Read this.

Good luck!

http://www.dedoimedo.com/computers/dual-boot-windows-7-ubuntu.html
[Motorola Atrix HD] Youngunn2008:
buy a decent sized harddrive and install ubuntu or mint linux on it. then you can dual boot win7 and linux like me. Just start tooling around with the linux command line (terminal) and learning how to think like a geek lol. Then take someones rom, and take it all apart. look at what makes up a rom... the apps, libs, frameworks, etc. Setup a build environment on your linux box, download the official source code from google, and try compiling it until you can do so without errors. at that point, if you want to start actually deving, you need to know java, cuz that's what source code is in mostly. there are alot of source code modifications avaiable on xda, try merging one in with the source code and rebuilding it and see if it compiles... if not, it''ll tell you where the error is. just play around with it, practice, ask questions, but actually jumping in and just making your self do it is the best way
[Motorola Atrix HD] Blackest Pain:
Thanks :D What size hard drive do you recommend and what rom should I dismantle?

(I'd thank both of you but apparently there's a thanks limit I didn't know about...)
[Motorola Atrix HD] frog1982:
each aosp build is about 30 gigs and Linux takes almost no room no matter which distro you use so when it comes to the size of the HDD it is all about the balance of how often you want to clean and how much you want to spend.
[Motorola Atrix HD] skeevydude:
That. I'll add that, on my PC, Linux uses 20GB of space...but I also have two distros installed on the same partiton with one being a chrooted build environment.

Roms use around 20-30GB as is, another 15-20GB is used up when compiling, so you want to reserve 40-50GB PER ROM to be safe.

If you do buy a hard drive just for compiling roms, BUY A SSD...solid state drive. That and RAM will help you the most. I'd expect just a SSD alone would cut my current build times in half.

I'll tell ya that without any Linux experience at all that you're gonna be in for a nice fun time.

Now, if you just wanna write apps, LEARN JAVA. You can do app writing on Windows and test on an Android Emulator (or your phone for at matter). No Linux necessary for just writing apps.

That said, if you want to get into compiling roms, you've picked the right place because I will help you if your serious. If you ask me a SPECIFIC QUESTION I'll give a specific answer. Don't ask "How do I use git?" cause I might not reply very nicely. Ask me "How do I update the kernel with the Dev Teams latest updates and I'll give you step by step instructions. I'm about to have 3 different roms I'm gonna have to compile. So if you just wanna pick one of them that isn't PAC, feel free to be the compiler of it. So far I've had multiple offers for compilers and only [MENTION=2804068]Youngunn2008[/MENTION] has stepped up and actually started doing it.

EDIT:

//I started building custom roms about a year into using Android. Had to. Nobody else on my device could (or would?) and I wanted more roms, simple as that. All I did was CM7, PA, and a few others, but it got me to where I am now. Kanged from Quarx's repos. I owe much of my Android knowledge just from watching his commit history (and for keeping us up-to-date with proper drivers). A good Dev Base is a good place to start from, just remember to give proper credit and thanks (and ask permission if it isn't open souce -- that's a big one).
[Motorola Atrix HD] Blackest Pain:
You guys are the best. I'm gonna start looking for the equipment asap. Although I need to learn how to write code, so I'm gonna go through Java.

[MENTION=4487948]skeevydude[/MENTION] I'll definitely hit you up when I need serious help

P.s. where do you recommend I learn Java from?

Thanks everyone!

[Motorola Atrix HD] Blackest Pain:
I'd click Thanks but I've seemed to run out of them (seriously, 8 thanks a day? Really?), so thanks. I can't read script at all (It's like looking a spanish, knowing it's spanish, and not knowing what it says) but I'll try to stumble through this lol
[Motorola Atrix HD] frog1982:
my suggestion is to download the SDK and start following the my first app tutorial. I did not understand code at all until I did that and then things started falling into place and making sense.
[Motorola Atrix HD] skeevydude:
Couldn't tell ya where to learn Java from -- I don't know it. I'm starting to learn it myself...meaning today....but it really depends on the weather on what I can for the rest of the day -- lost internet for most of yesterday during a thunderstom and since another one is rolling in I might have to shut my machines down. Also why I haven't been on a whole lot the past 2 days. After today its supposed to be clear skies ahead.

I've just been lucky cause even though I don't know Java, its still pretty human readable and easy to figure out what I need to do when I merge code.

For a bit of help Java=Apps, C++=Kernel/Hardware. Not necessarily 100% true, but for the most part it is.

If you wanna get into writing apps for making money then start with Java....the only reason why I'm starting with Java over C++. As much as I'd like to learn C++\Bionic to help with bug fixes for the kernel, hardware libraries, etc, I'm flat broke and can't find a decent job -- Java and a good idea could fix that. Combine my current situation with the fact that in 10-15 years I won't even be able to do my current line of work (construction is a young man's job) so I need to buckle down and learn a new trade that doesn't involve 8-12 hours work in the sun, crap pay, sore body at the end of every day, and no real job security or benefits.

If anyone reading the above is thinking that I'm thinking I could be the next App Millionaire...I'm not. I'd be happy just to break the poverty line (1-3 thousand a month or more than 18k a year)....cost of living isn't that high in Arkansas luckily. I'd hate to live in NYC\Random Big City where a crappy 1 room apartment's rent is a high as a high-end middle class home here.
[Motorola Atrix HD] spy_1134:
I would also recommend Java. I'm in an internship developing an Android app for a local company and it's pretty straightforward. I'm not very good at building GUIs, but I can manage the flow of code fairly well and I'm learning as I go.

I didn't know you were in construction, Skeevy... With how skilled you seem in all of this I would have thought you'd be from some sort of tech trade.

I've been looking into ROM development myself but it seems a bit overwhelming to me. I have always been interested in how operating systems are put together and built, but the most complex thing I've ever done was patch together a Linux server box for gaming and hosting an old website I had a year or two back.

I have worked with Linux for quite a while and I now run Ubuntu as a primary, no dualboot. It kinda sucks to get used to the lack of applications but I would much rather have the stability and responsiveness of a Linux system. Plus documentation is everywhere so anything is usually fairly easy to fix/get working.

If you guys could post some websites/threads with some tutorials or further reading so I can know what I am getting myself into, that would be awesome. I have always hoped that one day I'd be able to help you guys out with getting bugs squashed and features added.
[Motorola Atrix HD] Blackest Pain:
I'm in high school but I REALLY don't want to work at a fast food place, so this like a good way to earn so change. Once I get out, this will (hopefully) become more of a hobby for the next 25 yrs as I'm training to become an Electrician. Then when I'm done and in the early retirement that seems to come with many people in that field I'll hop back onto this. I also second that idea with the idea of website tutorials lol.
[Motorola Atrix HD] skeevydude:
Electrician is a good trade to get into. I wouldn't mind being an electrician actually. Especially since I know enough contracters, house flippers, and landlords that are always needing electrical done and hate paying the electrician (they can pretty much write their own check cause you GOTTA have that LICENSE to touch ANY wire)....why I always built my gates to run on a 12V solar setup (more reliable and I don't need a license to mount a panel and hook it up to a car battery; not to mention a grand cheaper).

Look, I'd post some links, but the best links are banned from a site like this where ethics matter. I'm broke so I can't afford the ebooks if ya know what I mean...hint, hint...find good looking book with positive reviews, google search "name of book .epub", ????, profit.

//see my above post for a quick glance at what McD's offered me....TL : DR version....negative 15 a week cause I factored in a thing called gas money.
[One (M7) Q&A, Help & Troubleshooting] dinoc:
Hi,

I've installed an custom Mail app which supposed to delete the exchange policies but it didn't work. The custom installation kit (via cwm/twrp) removed the original Mail.apk files and the replacement is not working. After reboot I've ended up with no Mail app installed.

Can someone guide me please how to restore my original Mail.apk please ?

Can someone provide me please the files I need to restore the Mail from 2.24.401.1?

Do I need only the original Mail.apk and Mail.odex files?

If I'm copying them in /system/app/ will be enough?

I've tried to restore it from cwm backup using nandroid manager.

It says it restore it successfully but after reboot it didn't install it.

There are no Mail files in systems/app

Any idea why is not working?
