Root [ROM] CTMod 3.80 (04/06/13)

So, my Prevail crashed recently. It froze one day, so I took out the battery and restarted it. Unfortunately, when I rebooted, it was consistently stuck on the KoumaKernel picture.

So, I finally restored from an old back-up (CT Mod 3.75). I flashed up to 3.80. I haven't wiped my sd card in a while, so I backed it up and did so.

I decided at this point that I wanted to try Kouma's SSM setting. I couldn't get it to work. I've been up and down the forums looking for a step-by-step method for getting it done, but to no avail.

Can someone direct me to the procedure for implementing SSM on my phone? If I'm understanding SSM correctly, I'd like to have a partition for apps (replacing internal memory), a partition for the davlik cache* (replacing internal memory), and a partition for swap (should this be on the internal or sd memory).

Thoughts and advice? I just want my Prevail to be as capable and lag-free as possible.

Currently, I'm running a Class 4 SanDisk card with 32 GB with a 4096 MB partition in Data mode. My intention is to overclock (200 min, 900 max) like I did before with the performance CPU control and an appropriate I/O scheduler (I forget which one I was using last time).

Thanks in advance!

*BTW, what is the Davlik cache anyway? I read that it takes away from
internal memory, so I wanted to eliminate that and free up the internal
for swap or whatever.

What is the Dalvik Cache? This info was obtained from :
DD Systems & Dbase Developments

It's a good source of information/ definitions regarding a lot of things having to do with Android. Most are brief definitions but you can get the gist of it. As always, Google is your friend when it comes to looking up info for just about ANYTHING> lol :D



Dalvik-cache
When your phone starts up, the Dalvik Virtual Machine looks at all your apps and frameworks, and creates a tree of dependencies which is stored in the dalvik-cache. This allows applications to run in an optimised state (and explains why your phone takes longer to boot up after applying a new rom, it
 
I am also having trouble with my GPS since upgrading to CTMod 3.80.

The problem SEEMS to be only with GPS satellites.

I select "Use GPS satellites". I deselect "Use wireless networks".

I go to the "Maps" application (or the "Local" application, or the "Navigation" applicatoin). I receive the message "Waiting for location" and then, after a few minutes "Your current location is temporarily unavailable". I have tried it in several locations around town.

If I select "Use wireless networks", I do not get the message that my location is unavailable. However, the location it guesses is not very accurate.

I tried downloading the "GPS Status & Toolbox" app, then "Tools", then "Manage A-GPS state", then "Download", but it does not fix the problem.

Any ideas? Thanks!

This was working in my previous version of CTMod. I did a backup and restore rather than a clean install.
 
Are you using the newest version of maps? I had the same problem with maps reporting that it was 'searching for GPS' until I updated

What a great suggestion, but I DO have the latest version of Maps.

Hi,

I run CTMod3.80 and the following GPS programs.... Paid version of "GPS Essentials", "FasterFix", paid version of "GPS Status" and I get perfectly accurate readings, same as with my Garmin GPS, almost no difference at all.....

Not sure what your problem is tho..... Hmmmmm

I THINK I now have it working. Here are the steps I took.

In settings, GPS, I turned on BOTH "Use wireless networks" and "Use GPS satellites".

I then opened the GPS Status & Toolbox app. It could not find my GPS location or any satellite signal. After 10 minutes, the phone froze completely and I had to remove the battery to re-boot.

After re-installing the battery and powering back on, I opened the GPS Status and Toolbox app. The app found my location within a few seconds as well as six satellite signals.

I opened Maps, which found my location immediately.

I now went back to settings, GPS, and turned OFF "Use wireless networks". Both the "GPS Status & Toolbox" and "Maps" have been able to find my location since (and I have driven several miles to confirm).

I don't know if the removing the battery step is what fixed things, or if it had to do with the sequence involving setting the flag, or both.

I hope that if anybody else has issues, that helps. Or, perhaps, somebody will discover a flag that needs to be set, initialized, etc., in the source code.

Thanks to everyone for the help!
 
First post here since it's the first time I've had an issue. I'm running v3.8 and I found that turning on bluetooth crashes the phone. I get the double vibration of a crash, the screen blacks and when it comes back it's at the searching for service stage of startup. I then only have a couple seconds to turn bluetooth back off or the cycle repeats.

I'm not sure how long it's been like that since I rarely use my earpiece. There's been no hardware or software changes other than updates since I updated to v3.8.
 
Hi !!!

First of all, thanks for this nice ROM !! I love it, very simple, not superflu softwares ; fast and beautiful :P

Quick question by the way, are some people notice issue on low mic gain on headset mode? I mean when I use headset with mic, people don't hear me very well... What about you?

Thanks :)

Did you delete Music.apk from /system/app? it's required for BT.
 
Hi Blooddawn, thanks for the great rom! It really has made the phone so much more usable for me.

I do seem to have encountered a weird little bug, though, and it didn't exist with my previous, default non-rooted rom. In the google maps app, if I go to my starred places and select one that is just an address, without a title, (not etc 'home', 'work', 'Jimmy's pizza', etc ) then it crashes every time. Entering an address in the search box works fine. It's only unlabeled saved places that crash it.

I would try to manually delete my saved places to see if that fixes it, but I don't know how.

You could always delete the Maps app and redownload it from the Play store. Make sure that you wipe all the data for the app before installing the new one though. You can do that in settings/apps or just use an app like Titanium. ;)

May work, may not. Def worth a try though. :D
 
The USB connection WON'T show the phones internal folder structure ( only shows your sd-card ). You need to use a File Explorer on the phone itself...... This File Explorer MUST have ROOT privileges.....
 
Ran a search in File Explorer, found no Music.apk. Would I just need to re-download that? Why would that file even effect bluetooth?

What file explorer did you use to search? If it can't view the root of the phone, then you're not going to find it.

Not sure, pretty sure it's the one that installed with CTMod, here's what I can find out about it.

Program Name: File Explorer
Version: 3.1.6 (201303075)
Developer: Hootan Parsa

It's been quite a while since I've used ctmod, but i do believe that file explorer is capable of searching the root of the phone, but i think you need to enable that feature.

The file I'm most familiar with is 'es file explorer' which is free in the play store.

If you install that app and open it you will see a bar at the top that will say something similar to this
(this picture is from my rush, but the options should look similar)

Press on the box that the arrow is pointing to until it says 'device'. Once there search for the system folder, select it and then select app. That is the folder where music.apk should be located

I think I like your file explorer better. There's Musicservice.apk, but not Music.apk.

ok, so you have a few options then. The easiest being to use blood's apk installer (found in the first post)

You will need to take ctmod3.8.zip, open it up and extract music.apk (from the /system/app folder) and place it in the apkinstaller.zip (also in the /system/app folder) then just flash it via recovery and you should be all set
 
Had some difficulty downloading CTMod (Firefox really doesn't like places like goo.im it seems), flashed it over and it's not crashing anymore. I don't have my headset handy to test it but before it was crashing even without it so I'd call this solved. Thanks Lordvincent!
 
I have had ctmod 3.80 since the week it came out. For a while now the phone has been lagging really bad. Sometimes it freezes altogether. The signal has been bad too, but it might just seem this way because of the lagging.

I have a 32GB class 10 card with 4GB partitioned for data.

What suggestions do you guys have?
