With partitioning you get a swap partition. Speed may be better using one, but in my experience it's not noticeable. I'm not saying it's not there but even without the swap partition, this build is fast which makes noticing an increase in speed pretty hard.

As for the sd-ext partition.

It's a great idea. All your apps and data get backed up to this partition without you having to do anything. When you shut your phone down, it backs up all the apps and data that you have added since the last reboot.

I think it's a little more complicated than that, but I don't remember how exactly it is done. Cope elaborated on the procedure somewhere in this thread. The backup function also does something when you boot up.

And that is also the downside of this function. It takes a little longer to shut down and boot up because of it. How long is depending on how much you've changed.

The good thing is, that when you switch to a new version of the build, you don't have to backup any data manually. Just install the new build. You can start with a new data image, so no risk of having an old image messing things up. At first boot, the backup function finds out, that there are apps missing and copies them to your new data image. That way updating your build is absolutely painless.

That's the idea anyway. Never really worked for me but it obviously does for others.

I no longer use it because I don't fully trust it. Because of that I always have to make a backup with Titanium and since I know this backup will work a second backup is redundant.

But check it out. It's a brilliant idea and it can really make life easier for you, if it works.
[HD2 Android SD Development] shamez23:
Ha, you got me there. I don't even know how to do that. And I don't fully understand Titanium. Many of the Titanium options sound similar to me and there is no real explanation what exactly will happen. But the way I do it seems to work so I'll probably stick to it.

What freaked me out was the weird behaviour yesterday.

I mean, the old build was working perfectly for weeks. I didn't change anything on my SD card and all of a sudden it stopped working.

But I've been around computers as a user for too long. I'm no longer trying to find out why such things happen. My only concern is how to fix them. And using Windows tought me that a fresh install usually is the easiest and fastest way.

I know this cost me many hours of my life but still I'm kind of gratefull to Microsoft for them having hammered that lesson into my head.

Ah, another one.

Well, I think there are more of us than we might believe and if all the people with problems, outside small icons and green LEDs, would follow our lead this thread would be a lot shorter. And if the small icons and green LED people would have read the first post, the thread would be even shorter. Only updates from our devs and real fixes to real problems. How strange a thread that would be... .

Have fun with your working AmeriCanAndroid.

shamez,

next time u upgrade with a fresh data.img and it has issues with FC's, even after our fix permissions, go to rom manager and use the fix perm's there.

in the times i've upgraded with a fresh data.img, i ended up having to do that for some of my apps.

so while the backup isn't 100%, it's 98%, and very worth while to have.

the swap partition is nice, tho not so noticeable.

Using google and titanium for backups

Google is great for backing up contact and email data. I found out the hard way, way back when i had an audiovox smt 5600, one of the first smart phones (htc bought audiovox's phone line). I lost my contacts at one point. While I was able to import from my work's outlook contacts file, I was irritated enough to look up how to avoid that problem. Since then, I've used google sync. Now, poof! All my stuff is there when I log into the account from the phone.

I looked up titanium after losing some apps. It looks dreadfully complicated at first. BUT, if you look carefully, the main options are to back up user apps or system apps. I don't back up system apps, only user apps and data. It's pretty fast, and if you've recently backed everything up, you don't really have to do anything before a new build. It allows you to identify new apps that haven't been backed up. The thing which was unintuitive to me was the "batch" process. Hit the center button and click on batch. It will give you a BUNCH of options for backing up or restoring. But, just look for the one that makes sense - like "backup all user apps". It helpfully identifies how many apps will be 'affected' by this. Finally, if you have to wipe your SD, for goodness sake, back the Titanium backup folder up - in fact, do that regularly. Having it backed up on your phone is not helpful if you wreck the card or phone, etc.

Good luck!!!

Yes I do read, but i would just like to verify. To "upgrade", I run the android as a fresh install. Then I copy the data.img and downloads folder? This will keep previous settings and apps?

I copied entire SD card to computer, so I didn't lose a thing.

Again, I just wanted to make sure before I did anything. The 3/29 build is the first and only android I have used. ****Fantastic Build**** The Data drops became too annoying and has twisted my arm to install latest build. But My God the thing ran smooth. Faster than Win6.5. Design and user friendliness was flawless.

Thank You Cope & Warren for all the work you do for us. Because of YOU, my HD2 is still fresh and fun. With your talents, it is beyond me why Google Dev Team hasn't offered you a paycheck for your skills. I am sure AmeriCanAndroid has greatly increased Google's market.

~Bdwlf2~

**Correction** I did have the build before that 3/29 release, but I didn't have anything anything on there to really save. Is there a way to use the old boot up screen? (the one with the line going back and forth)
[HD2 Android SD Development] shamez23:
See, that's what I thought, too. And I tried. I tried all the tricks I learned from reading every page of this thread and copes thread of his first build. To no avail.

Formatting the SD card was the only thing that did help. I tried to avoid it, because it takes quite some time to backup the content of my card and even longer to restore it but at least it works. And in the end it turned out to be way faster than all the things I did to avoid it.

That's exactly what I like so much about this build, well every SD build actually, but AmeriCanAndroid is the best of those. It's on your SD card. If something gets jumbled up, you just format it and your good to go. If you don't have the time to do it, you can fall back to winmo for a short time.

You don't have to think about it, no panicy moments like when you flash your phone memory and pray for the screen to turn back on instead of finding out you bricked a 300€ piece of hardware.

The sd-ext backup function really is a brilliant idea. I've had my card partitoned for quite some time but in all that time it just didn't work for me. It seems to be stable now but I chicken out easily when it comes to things like this. I would still be using Titanium because I trust it. So the ext partition is wasted space on my SD card.

But I don't update with every new build. I have no reason to. I probably could still be using one of the builds from end of february and I would be happy with it.

The data connection is not very important to me, I don't have a data plan and therefore I almost never use it, except for navigation with google maps but that's a very rare occasion. And I don't use BT. The rest has always been working for me.

Mh, that is something you have to be carefull with. Sure, all the long time followers of this thread and you of course are tired of all the repeated questions but trying to keep a thread clean is a delicate matter. People can get pretty angry when they get blocked. Sure, most of them had it coming but one slight misunderstanding and you block someone you shouldn't have because he had a real problem, something new, or a good idea you didn't take serious at first look.

It happened before, you know that.

And it's a lot of work. Probably easier to let the users take care of it.
[HD2 Android SD Development] warrenb213:
Yea the only thing about the mod right would be to review the posts from day 1, catalog the important ones, review them with cope or myself, and then delete the others. once we get to about a 3 week latency on the thread, it'd just be minor clean ups. the good thing is that with the catalog of important posts we can better leverage that info into the FAQ section and then clean those posts out as well.

in fact, i wouldn't want the person we appoint to cross in any closer than the 3 week latency, mainly because of the reason you point out. :)

as a side note,

I think even the built-in wifi hotspot(under settings) may be working as well. surprised it's working when we're root but hey whatever if it works it works, though we will always include the expanded wifi tether app in the future.
[HD2 Android SD Development] bdwlf2:
I tried the Tether on the last build i had. I had a coworkers iphone & a motorola hooked to it. Was very slow, but a simple setting adjust and both phones were opening net pages instantly while i was surfing as well. The Tethering is a very nice option.
[HD2 Android SD Development] shamez23:
I don't need to backup my emails. They are always on my providers server. I never started using outlook, always do it online over my browser.

I've been using the internet pretty much from day one. Well, not exactly day one but lets say day one of when it started to get available to a wider public. A 14K modem was a pretty fast thing back then and still it was pretty useless because almost no one I knew had a internet connection, many not even a computer.

It came pretty much as a surprise to me, when I had the first cases of people complaining about having lost all their emails after a computer crash. I wondered how the hell they made that happen. That's when I found out about outlook and that they downloaded their emails and erased it from the server.

Email to me was always something different than paper mail. Something that happened on the internet and stayed there. Different approach I guess.

Anyway, enough of going down memory lane.

Email backup is no problem, I just redownload the last couple of emails after a fresh install.

But the google online contact backup came in pretty handy when I had a faulty backup a couple of updates ago.

I was kind of reluctant to give google my contacts. Not so much because I don't trust them but because some of my contacts don't. But Google is pretty sneaky and you have to be quick with deactivating that option. I wasn't, so google has my contacts.

Saved me a lot of trouble, though.

What I don't know how to do, is backing up app data to google, like warren suggested. The apps I bought always are in "my Apps", but the rest isn't.

If there is a way to get them back via some google backup feature I'd be happy to use that.

But Titanium is a good alternative. I do things exactly like you described them.

Except for the adding new apps to my old backup. I tried that once but it didn't work too well. Some apps where missing and I had to go back to my old build and do a fresh backup. I've been doing that ever since. It just takes a couple of minutes, time well spend if it makes sure that the backup is going to work in case you need it.

Maybe docent could use your directions and make another chapter in his FAQ out of them. Could be a big help for others. If they would read it. Those that would need to do that the most, sadly seem not to do it.

LED problem

Before you attack me...I've read the LED FAQ page...I've downloaded LED me know and the led light still remains lit...
[HD2 Android SD Development] bdwlf2:
So using OLD data.img and download file will NOT save your apps and settings?
[HD2 Android SD Development] shamez23:
Good idea. I didn't even think of that. But I pitty the person that will have to do that. Close to 600 pages. That is an awfull lot of work.

Question is, if it is worth it. It sure would slim down this thread but how much use would it be. Sure, there are people that take the size of this thread as an excuse.

It's easier to just ask, then to go through so many pages but would they really not ask, if the thread was only 200 pages long? Or make that 10 pages. That's what cope always asks for. Read the last ten pages or the pages since the last build update.

You even point out were those posts start and people still don't do it. They also don't read the faq, the place were the content of this thread is summed up. They can't even be bothered to read the first page.

Sometimes I think you should build something that would brick their phones. Put it in the download section. Put in a warning, in red, huge font. I wonder how many posts we would get from people that put that one on their phones. Too many, I guess.

It would be a lesson learned but there are new users every day.

It's really sad but no matter what you do, no matter how much effort you put in, things won't change.

We have a saying, where I come from. Roughly translated:

Every day some new idiot gets up out of bed.

May not sound friendly but it's true.
[HD2 Android SD Development] shamez23:
No. Using the old data image will keep your files. The data.img is the file that contains the system. That file IS Android.

But using the old data image doesn't always work and it won't work forever.

It's like buying a new car and keeping the old motor. Cruel comparisson but it's close enough.

The old engine may be a good enginde and still have many more miles in it, so you could use it for your next car. You could maybe even use it for the car after that but it gets older and older and one day it won't work any more.

If your new car is too different from the old one, the old engine won't fit.

That's what happens when the devs do some big magic thing with the build to improve it.

That's why I always make a fresh start, with a new data image. Just to be on the save side and not get caught by some error that silently slipped in.

You don't have to do that, you can try using your old image. If it works, perfect. You just saved yourself a lot of time. But if it doesn't work and you get problems, don't come here to find a solution and blame the build, before your tried using a new data image. We have enough people here, that do exactly that, that's why this thread is hugely long.

You need Titanium backup or some other backup tool or the sd-ext backup function, if you start with a new data image and want all your old data back.

Clear enough now?

I thought I read about the how to in the faq, but I may be wrong, it's been a while, but I don't think so.
[HD2 Android SD Development] shamez23:
So, you donwloaded the app. Did you start it?

[HD2 Android SD Development] MarsHD2:
Yes, one way I get rid of it is when I test a certain notification so it can start blinkly then once it stops blinking, I end the test...but then it comes back again a little later. Is there a way to just disable the whole LED thing on android, I really don't need it...
[HD2 Android SD Development] bdwlf2:
Ahhhh, see I thought the Data.img was for most of the add-ons. Like it was like an external drive (so to speak) for the system, not actually the system itself. Then obvioiusly I wouldn't want to use old image because all the goodies from Cope & Warren wouldn't be there. I thought that info was in the smaller files (rootfs, 240buildprop, syst.ex2, etc....) And because Android creates the data.img file upon installation, I assumed it was mainly configurative files that were being generated that just held app data and other disposable info not neccassarily important to the functionability of the build itself.

Thanx for clearing that up. I mainly use Amazon app store, so everything is server stored, just click and install. Anything else is most likely in my downloads folder I saved.

~Bdwlf2~

Wasn't the Data I was really worried about, more of the settings. I have poked through the system several times and personally tweaked things. Those setting is what mainly what i wanted back, instead of trying to remember everything I did. Like the little battery icon on top, data transfer settings, animation frame speeds, cpu throttle..... All the little things that make your android personal. Data..... not worried about. That is easily restored.
[HD2 Android SD Development] JustX:
Really? I shall update to this one then...
[HD2 Android SD Development] efebe:
Is anyone else having problems with the SD card? ... I have dual boot windows phone 7 and this android build, when i get into android (using magldr), it doesnt show any SD card... im not sure if someone else is having this same problem?
[HD2 Android SD Development] JustX:
Did you read the information on the first post about using MAGDLR? Is this the first time you have used this build?
[HD2 Android SD Development] shamez23:
Ah, well. Not exactly. It's a little more complicated. The data.img is not all of Android. It contains the stuff that is important to you, like apps and settings. You can use the old image in a new build and still get the goodies. But that is were the problem lies. The data.img is connected to those files outside it and when the changes outside get too big, it won't fit anymore. That was the example with the engine.

Hard to explain, really. You would need someone like warren or cope or one of the other guys that know their way around the bowles of this system to explain it.

But as I said. Try the old image unless stated otherwise in the download section. If it works, your good to go. All the new stuff without loosing any of your data and the least amount of time needed for the update. If you run into problems with the old image, backup your data, create a new image and restore your data.

And always, always make a backup of the whole Android folder to a computer before you do anything. In case something doesn't go as planned, you can always go back to the old system.
[HD2 Android SD Development] efebe:
Yea i read the info, and this is my first time using magldr to boot an android build :P hehehe
[HD2 Android SD Development] shamez23:
Just play around with the settings.

Untick all the notifications and the LED should stay off.

After a bootup you might have to start the app again.

You can also plug the phone into a computer with the usb cable. Plug it off again and the LED should be off but only as long as you do not reboot your phone.

It's something related to cynogenmod. They have to fix it. It's nothing the devs of this build can do.

If you can't live with it, use another build.
[HD2 Android SD Development] daniel_kiefer:
It works fine for me. Are you sure you set up your partitions right? Did you follow the magldr steps for this build? Like I said, I have no problems. I'm a pretty thorough reader though.

[HD2 Android SD Development] daniel_kiefer:
I know one of the more confusing parts for me was the partitioning. Make sure for wp7 it's unformatted and set to primary, and your android formatted to fat 32 and also set as primary. I think the wp7 partition had to be bigger also. Not sure. Wp7 has a funny way of dealing with the sd card.

I used this tutorial: http://xdaforums.com/showthread.php?t=944288

Could just be a bad sd card too, or maybe just need to re format the android partition.

I have set everything to 10db, but doesn't really make a big difference. In WM6.5 mode the external speaker seems almost twice as loud. Yes, i looked at volume controls.
