[AT&T Samsung Galaxy Note I717] BlackZenith:
Since we are on the subject of backing up and restoring... is it possible for TB to remember which apps you had frozen and refreeze those apps during a full restore?
[Android Q&A, Help & Troubleshooting] mistermentality:
I know I'm likely to get criticised by some for saying this but some of us have to use task killers.

My phone has an average of 140 mb free after it boots up. Add to that apps that stay in ram even when you close them and you can have as little as thirty or fourty mb free.

I've seen apps such as facebook and tapatalk, and even some games, taking up ram even though I don't want them used once I exit from them...and when my phone gets to around fifty mb free or less it can get slow and unresponsive.

A quick kill of un needed apps makes the os perform as it should again.

It's nice to say android clears up ram as needed, and it does, but try playing a decent hd game when your ram is low and, unless you kill some apps first, you're left with a black frozen screen while it tries clearing some ram. In some cases your phone can be unusable for a while, on mine when this happens the capacitive buttons stop responding to keypresses.

Now on ics with 1 gb ram this isn't an issue but for those of us with less ram and / or an older os it is.

Ideally we could configure non system apps so that if we don't want them in ram when finished with them then they cannot auto restart.

It is a simple fact that two identical phones will perform differently if one has lots of free ram and one has most ram in use, I use an on demand task killer so that apps that stay around on exit can be stopped from eating ram and slowing my phone down so for me a task killer is not pointless specifically because it frees up ram so that something memory intensive can be run without slowing my system while android tries to make room for it.

So while I agree with the theory, in practice task killers can be useful or at least on demand ones can.

[Android Q&A, Help & Troubleshooting] gruntparty:
I agree with how Linux handles its applications. I switch between WinXP and Ubuntu and the overall way tasks are utilized are similar, but linux does a better job at handling running applications. On windows i have Chrome open and with 9 tabs open im hitting 1.5 gb ram used. Same situation on linux i find myself hitting around 500mb of ram used. Im sure this applies to android as well.

On a side note i find that people who "Kill Tasks" are just running them because they can and are usually fixated on seeing a large amount of ram free. It just adds another reason to stay on their device. Just my opinion.
[Android Q&A, Help & Troubleshooting] Markuzy:
An alternative to task killers for rooted devices are apps that blocks app from running at triggers so nothing is killed at all; the apps don't run.

Eg: the autostarts app.

[Android Q&A, Help & Troubleshooting] mistermentality:
I use one to make sure my phones already low ram does not drop so low my phone becomes slow, which it does when you get to even just fifty mb free ram left. And to kill those applications which do not exit properly.

On an android phone that has 512 mb ram if ram gets eaten up the phone goes slow, and I know it is not just me because other users with similar setups have same issues. So I think it is too general an assumption to say we all use task killers for say a cosmetic rather than practical reason though I'm sure some do.

[Android Q&A, Help & Troubleshooting] mistermentality:
Unfortunately this only stops apps auto starting at boot and once you have used an app and exited it, a lot stay in ram.

Some restart when killed some don't but when your phone is on permanently as many are, having low ram can quickly be a problem.

I think part of that is the phone manufacturer as 512 mb ram, with just 140 mb free at boot, is rubbish on a dual core 3D phone but whatever the cause I find killing tasks helps make phone run better.

[Android Q&A, Help & Troubleshooting] lewymaro:
I used to kill tasks when i was on Android 2.1 an 2.3, but since 4.0 i feel my phone gone strangely fast, and i don't need to use task killers anymore. Phone is LG GT540, so... :cowboy:
[Android Q&A, Help & Troubleshooting] mistermentality:
I used to love my gt540. Didn't know you could run ics on it though, good phone for the price but didn't like the resistive screen though the phone itself can take some serious punishment and still keep working.

I love lg for their build quality, pretty hard to break them with dropping etc, but unfortunately they do bad with the software side.

[Android Q&A, Help & Troubleshooting] al3nkbootas:
Good topic, I don't like the task killer!
[Android Q&A, Help & Troubleshooting] SifJar:
In general, yes task killers are bad. But occasionally it IS necessary to kill an app. Sometimes an app will freeze. Then it needs to be killed to be able to use it again. But you can easily just go into Settings > Applications > Manage Applications, find the app and then Force Stop it. So there's no real need to have a task killer. Although I do like to have Watchdog on my phone, as it shows the amount of available CPU cycles being taken up by each app, so you can make sure background apps aren't using too much CPU. (It does also show RAM usage, but it sorts apps by CPU usage, by default at least).
[Android Q&A, Help & Troubleshooting] zapcow:
Linux has nothing to do with the management of an application, the applications under Android are sandboxed in java and there is this dalvik machine that takes care of everything.

I don't get why people keep mentioning this kernel over and over, also for the biggest part of its history Android did not use a real linux kernel with vanilla flavour, only recently the Android kernel was merged with the linux kernel mainline.

This is one of the very first Google video about Android http://www.youtube.com/watch?v=Mm6Ju0xhUW8

edit: In this series of videos there are also references to memory management and app management.

[HTC Amaze 4G] Nshih422:
This is awesome. I really appreciate this, but I feel like I'm just following instructions and not really learning anything. Even with the compile cm9 from source I felt the same way. I guess I just need to play around :-)

EDIT: Is there a way to do the second part without Windows, still in ubuntu? I'd have to swap hard drives to get back on Windows.....long story.
[HTC Amaze 4G] ziggy46:
yea, just look up how to use the kitchen in linux.
[HTC Amaze 4G] KnowledgeBroker:
I was wondering why he switched to windows for that part.. for me cygwin install didn't work properly, but i MADE IT WORK.. just look up dsixda kitchen and follow the instructions for the ubuntu setup.

And note to anyone: installing ubuntu itself can be a *****, building a kernel is not nearly as intensive as compiling a whole rom from source - you can install ubuntu in a virtual machine and build in that, it will take a little longer, but it works just fine..

And to anyone who wants to learn, actually building the kernel isn't going to teach you as much as looking at the git commits and doing some Googling.. if you look in any of the threads where kernel discussion has been had, you can see a lot of useful info.

I suggest that the OP add a couple of notes about changes that can be made before the make command.. how to make those changes will be more educational that the process itself(tho it is helpful as hell, very well written!)
[HTC Amaze 4G] ziggy46:
yea i planned on expanding the guide to have the different mods you can do in it. :D
[HTC Amaze 4G] freakboy13:
Ziggy nice write up...
[HTC Amaze 4G] brainbone:
If you're swapping hard drives (have only one machine), perhaps you should look into using VMware Player or VirtualBox.

For the free VMware Player, you can use http://www.easyvmx.com/ to build empty VMXs to get you started.
[HTC Amaze 4G] Nshih422:
I know about vm, I'm a certified computer tech. It's something about my old drive not playing nice with ubuntu. I swapped this hard drive only installed ubuntu and have been using it as my main machine. It's just my laziness that's preventing me from having Windows and Linux.
[HTC Amaze 4G] ziggy46:
yea, the main reason i made the guide go from linux to windows is because the kitchen it so much easier to get setup in windows. (so it makes this easier for the new folk) but yea, the kitchen works perfectly in linux as well. you could also make a vm box of windows within your linux machine.
[HTC Amaze 4G] hasoon2000:
Somethings don't play nicely in Windows. When I try to build up ROMs from the kitchen, it tells me Cygwin may have an issue doing some parts. When I see that, I finish it off my other laptop that has Ubuntu on it.

[T-Mobile myTouch 4G Slide] fsured:
Well I decided to jump the hoop and go for rooting my mt4g slide. Was doing great and unlocked it using the lovely All-In-One tool kit and couldn't get the phone to show S-off. I figured I needed to get this done before installing a rom's as I tried 2 different ones and neither would work. Tried a few different things and still wouldn't work to get S-off. Long story short, now I'm in a boot loop where the phone automatically goes into the boot loader. It will start up and show the mytouch splash screen before going into the loader. It will scan the sdcard for files and say there isn't a image etc and go back to the main boot loader screen. I can't do anything beyond that. I hit recovery, factory reset, and nothing. Tried putting roms and see if it would out of the blue read one.

It's my fault for taking the risk but adding a bit of insult to my injury is my back up phone, G1, won't even turn on now. So now I'm kind of phone less. Any suggestions on how to restore hboot?

take out your sdcard and use an adapter to put a stock PG59IMG.zip on your sdcard (make sure its named PG59IMG.zip) and go back into the bootloader. It will confirm if you want to install the zip and in 10 mins you'll be back on stock. Oh and ^ plus one please next time post in general as this has nothing to do with developing.

"tried a few different things" to get S-Off?

There are two ways of getting S-off. One is done with Revolution if your HBOOT is earlier than 1.45. The other is juopunutbear if your HBOOT is 1.45. Did you check your HBOOT version before "trying a few things"?

Did you read the instructions for the all-in-one toolkit? Or possibly just follow the steps in order in the program? It's specifically designed so you don't need s-off.

I'm assuming you must have flashed CWM recovery since you said you did a factory reset. Did you do Juopunutbear or revolution, or are you planning on leaving S-ON? If S-ON, Did you flash a kernel(boot.img) using the toolkit? If you can get into HBOOT and get into recovery, there's no reason you should need to revert to stock. However, if your plan is to continue doing steps before reading the instructions, you should probably revert to stock anyway before you really do brick your device.

This link will provide you everything you need to get your device running. Just follow the spteps from the beginning. If your bootloader is already unlocked from HTCDev, then start at the step directly after unlocking the bootloader.

[T-Mobile myTouch 4G Slide] davidf9:
The toolkit worked well for me (even though it was my first attempt at anything), so I guess I'd echo that. It also matched with the step-by-step guides on stuff I found elsewhere in the forum. BUT there is a real difference in the method and order of things for the two hboots, hence KarriOn's questions.

However, having rooted and S-Offed, I then got a bit cocky and managed to end up in a not dissimilar position to you! Total panic, but I managed to get out by thinking through what I'd done, researching, and the cause and hence solution became clear. Took a night sleeping on it, and 2 hours.

what HBOOT?

Did you unlock the boot loader?

Did you get recovery on

Did you do a backup before going any further?
[T-Mobile myTouch 4G Slide] fsured:
I followed the all in one tool for everything. I've finally been able to get into cwm recovery. For awhile it wouldn't and I gave up for the night. Came back yesterday morning to tinker with it more and it worked. I've tried flashing the superSu.zip file in cwm and after it reboots it still reads s-on. But either way I can't get the phone to do anything other than boot into the bootloader screen. I'm going to check out the link about 2 posts up and tinker with it after work. Thanks for the replies!

Oh yeah, that is the tread I used and the tool. After getting unlocked from HTC I tried flashing a rom and it wouldn't work. Figured I needed to get s-off for roms also. That is where my error started.
[T-Mobile myTouch 4G Slide] karri0n:
You don't need S-Off for ROMs to work. It sounds like you didn't flash a kernel after installing a ROM. The instructions on doing this are listed in the all-in one tool thread, the "flash ics roms with s-on" thread, and even on the all-in one tool interface itself.
[T-Mobile myTouch 4G Slide] eparico:
Flashing SuperUser won't get you to S-Off. Hasoon2000 has two different toolkits. One that will guide you through the rooting process and the other on how to gain S-Off using the Juopunutbear method. Having S-Off isn't necessary to root but it will take a few extra steps to flash a different ROM with S-ON. I was too much of a chicken to try the S-Off method since there is some risk involved but several have reported that it worked successfully for them.
[HTC Rezound] GrayBoltWolf:
Download link is back up again!

I am so tired of all the developers leaving, so I decided to step up, and do it myself.

My first ROM ever, and after a few days of fun, here it is! I learned a lot and hope to do this some more.

WolfROM 1.0

​

Features:

De-Sensed, removed worthless sense crap, (Without removing the Sense 4 Launcher)

De-bloated

Choice of 3 launchers, Apex, Launcher Pro, or my favorite.... the Sense 4 launcher!

AOSP lockscreen

ICS blue status bar icons

Dolphin browser, Go SMS Pro, MyVerizon (Installed and working!)

Rooted (working on SuperUser, having some problems, but everything still works)

Original bootanimation

Many other things that are escaping my mind at the moment.....

joebrady119's HQ Camera

To get to quicksettings, tap to the left of the gear icon in the notification window.

Just a very simple and cool ROM for those crack flashers. :D

Based on Nils Buisness Sense 4 ICS ROM. All credit goes to him for making a great base ROM!

Downloads:

Download Page--> Click Here!

For users on 3.14.605.5 RUU or later, just flash WolfROM.

If you are S-On, flash WolfROM and reboot to bootloader. The PH98IMG will be there.

For users with GB, flash WolfROM and then flash "Patch-New-v3-ROM-Old-FW.zip " (credit to NilsP) after you flash WolfROM.

Mods:

HTC Lockscreen (Get it on the downloads page, place it in /system/app, and then reboot. I am working on a flashable zip)

Bugs;

Data arrows don't work (working on a fix), HDMI doesn't work (gives you this weird like stretched, doubled imaged thing), Bluetooth (media works).

Donations are accepted but are never expected!

Please, also donate to NilsP for making a great ROM to build off of!

If you have any ideas or other bugs, please PM me!
