Going From JF rc33 to thedudes 1.5 issue

Ok, I asked this in theDudes thread for this release but it wasnt answered.
My question is this. I have went from Rc33 to the 1.5 cupcake build. I absolutely love it. Now, on JF's build i was using the apps to sd mod. So currently I have been running all my apps on my sd. Now that I have updated to theDudes, all of my apps are there, but my phone storage is pretty low.
Are all my apps on my sdcard still? All of them are showing up on phone. how do i figure this out, and or get my phone memory back??
thanks guys!

bump
Anybody suggestions?
All i know is I did an update without a wipe comming from jfrc33 with apps to sd mod by lucidrem. Now all my apps show up, but my available memory is 33mb.
Did my apps somehow make it back to the phone memory? I read that after an install there should be 51mb free. So im missing almost 20.
Anyone?

If you went from RC33 to TheDude's you probably need to do a wipe and then flash TheDude. Then, create all of your symlinks again. YMMV, but that's what I've heard recommended. I had to wipe going form Haykuro's to TheDudes and those were both App2SD versions and both based on 1.5 --- I'd imagine you'd have issues coming from RC33 to 1.5 without wiping. But I could be wrong.
and 33MB seems like a lot of available room to me. I have my apps to SD and I have 26MB free on /data --- and that's after freshly clearing my browser cache. (I dont have my caches to SD yet.)

Well, oddly enough when i flashed and didnt do a wipe, my phone came back exactly as it was b4 it was powered off. I noticed that the memory was alot lower than what i was used to getting, but that could be the build.
Anyway, I wiped the device and had to do the whole initial setup and all.
From this point, how do i do apps to sd on this rom? can you point me to a link?
I know with jf's you run the commands through the telnet.. but i dont think thats the case here. I looked through the thread, but nothing.

look under the applications tab for dev tools. There is a terminal emulator there.
type su at the prompt then enter the commands. You may need to boot to the recovery console: (power down phone, press home + power until text appears, press alt + x) Once at the recovery console type the sym links to complete the transition.

Search is your friend. http://android-dls.com/wiki/index.php?title=Haykuro_Apps_to_SD
Make sure you have your card partitioned correctly first.

I went straight to Dude's .8 apps2sd nowipe from JF's RC33 and everything works perfectly but I only have 20mb free.
I've only moved apps, not data or cache, so that may be why. I'm seeing all these people claiming 50-70mb free though and it makes me jealous. I may be just imagining it, but it seems when I start getting down to this amount of free space, the phone tends to get a little laggy.

I had the cache moved to SD for a long time. Then at around 80 installed apps, internal space started to become a real problem. I got tired of managing apps on a daily basis, not to mention the dismal performance of the phone when memory gets tight.
So I broke down and bought a class 6 card and partitioned. I initially tried moving both apps and data. It was a disaster. I never could get to work...either it never thought the apps were installed, or the phone got stuck at the flashing android.
I tried scripts, and even making the symlinks by hand. Nothing helped. I think I must have done a factory wipe about a dozen times trying to get it to work.
I finally ended up just moving the apps, but not the data. That worked just fine and has been working ever since. I think people who are moving both must not have very many apps installed in the first place.
If space starts to get tight again, I'll try moving the caches. In the meantime, I'm hoping Google/T-Mo makes and effort to resolve the lack of internal memory another way.....other than expecting us to buy a new phone.
I'm keeping a sharp eye on NuviPhone....4GB internal memory...I'm sure it won't be long before someone has Android running on it.

I have the same issue. 19mb available after cleared cache. updated from lucid rem mod to .8 apps2sd. had about 42mb free before update. It showed me having 18mb free originally, not sure why i have 19 now, although I did uninstall powermanager since it doesn't work on Dudes build. but that should have been installed to sd?!

Yeah I Get What Your Saying I Have Like 59MB Free But I Don't Have Apps Installed To SD-Card. I Would Love If T-Mobile/HTC Made An Update Where We Could Just Use Our Memory Card To Save Apps And Data/Cache Without Rooting It, That Would Be Insanely Crazy I Have A 8GB SD-Card But I'm Not Sure It It's Class 6 Dam, Bought It For Nothing.

I just moved dalvik-cache to sd card and went from 18mb available to 57mb in Dudes build.

Try this
I actually ran into the same senario when I went from RC33 to theDudes cupcake! I went back and reflashed my phone and went back to the RC33 build with mod, think that was 1.42, then instead of using LuciREM apps to sdcard i tried using MarcusMaximus's. They both move apps to sdcard and both work great. I realized on MarcusMaximus's edition after running commands in the terminal we rooted from recovery and mounted in recovery as well. I guess that did the trick for me, so now i'm using theDudes cupcake on a apps to sd command from MarcusMaximus. Thanks to all these guys, they rock from JF, LuciREM, MarcusMaximus and theDude. Hope it helps!

I agree with u, but im wondering if it would be possible to install apps directly to the SD card, i hope google can do something to make it work. If tried allocating my apps to my sd card twice and i failed, the first time it seems i got success but after i while, applications like ahome forced me to close, which was not good, not only with this one, so then i thought maybe it would be good idea to reboot the phone so i turned off and when i turned on, it got stuck in the splash image, buu anyway i fixed by deleting my ext2 partition and rebooting my phone with another build...after a while i tried to make a partition using only the phone and running some command...and i got the same problem, so i guess allocating app2sd doesnt work for me .Anyway the internal space still is not a problem for me cause i have 71apps with 20Mb free..not so much i know....im still having JFv1.42 RC33 but i guess i will move to dude .8 build i heard a lot about that build...so seems to work good for now...but people are demanding many things from his build. What im happy is to be part of this community cause when i got the problem with my phone i couldn't use it for 2 days, i didn't know what to do..and was asking questions to everyone, but i guess everything is in this forum, we just have to read, i learned a lot thanks to the contributions of guy like you, that share experiences with their phones...thank u guys and of course to the developers that make android be better.

Apps2SD:Am I going crazy or just not paying attention

Before I get flamed, I know I posted this in the Sapphire General section, but the reason I am posting this here is 'cause I'm looking for more info from a different crowd. Thanks in advance.
Here is my dilemma.....
Cliff Notes Version:
Got the MY3G, did all the good stuff (rooted, CyanogenMod v4.0.4, Apps2SD, etc.,). However, after I configured Apps2Sd and the SD card with the partitions I could have swore I had 289MB (or something close to that) of free internal storage. I have installed numerous apps and it went down to 278. I know the Apps2SD worked, however what is taking up those 10 megs??? After I noticed this I began rebooting the phone after app installs to see if maybe the apps need to be pushed to the SD card during reboot. No luck. If anyone can throw me some advice or point me in the right direction that would be badass.
--------------
your_helpfull_hand provided this answer:
You do know cache does take up room? Also if you installed apps thats why it went down. its normal
--------------
I replied with:
your_helpfull_hand: This is my first Android based phone so thanks for taking it easy on me. Ok, I forgot about the cache....So, if I understand this correctly the apps will install on the SD card but the internal memory will still slowly decrease but not all crazy as if I was installing straight to the phone??
One more thing, after configuring Apps2SD how much internal storage should be left with (the phone being clean after loading Cyanogen)? As I mentioned I was originally left with 288MB or close to that. Is that about right? Should it more or less?
--------------
So, that is where I am at. If anyone has additional info that would be awesome.

Using a swap file in /data partition?

Hey guys!
Just been racking my brains for ways to try and speed up my poor little G1, as its quite a sloth these days In my quest for more memory, I have tried using swap on my SD card, and despite having a Sandisk Ultra, it does (overall!) seem to make my phone much slower, I also tried compcache (still slow) and compcache with backing swap (slow again). It does have some benefits I have noticed, but overall not, so I turned it all off.
I was thinking about the different partitions in the phone, and I'm assuming that the /data partition is probably faster than an SD card, I could be wrong. So I was thinking, why not put a swap file on the much lesser used (got apps2sd) /data partition in the hope that it wont be as painfully slow and supply some better swap? I used DroidSwap to set the location of the test 16MB file on the data partition, told it to go ahead. It created it, did a mkswap on it, then for whatever reason couldn't swapon on it. I then tried a mkswap on the file manually in terminal, worked fine, then swapon, get an 'invalid argument' error. Tried to google it, and I didn't really find anything of use. I'm running the one just before the latest Cynanogenmod. Can anyone give me some insight, or tell me if I'm just on a wild goose chase and wasting my time?
Thanks in advance!
Chris

I think it will be something to do with the filesystem
I may be wrong, but I think yaffs are 'fractured' and therefore no good for what you want
In anycase it probably isn't a good idea to hammer out with swap you only get so many read writes , and it is much easier to replace an sdcard.
there is an app called auto memory on the market, you may be able to get some use out of that.
when it comes to swap there is always some debate about what's best
some, none, lots, etc
personally I'm in the “lots as soon as possible“ camp
I would rather have real memory available to my current app than having some app I'm not using hog it. having a lil bit of lag while pages load back from swap is better than waiting for a killed app to reload, which is what happens when you have no swap and lots of apps
but at the end of the day no one is wrong, all options have pros and cons.
all very much depends on your usage.

[Q] Will future versions of the Android OS fix this blasted "out of space" problem?

[Q] Will future versions of the Android OS fix this blasted "out of space" problem?
So I have been an avid fan of Google for many, many years. I was looking forward to the Google phone before any Android details came out. So I naturally jumped at the chance to own one. But lately, I'm starting to have a change of heart. These constant out of space warnings are really getting annoying.
So much in fact, I don't know that I want my next phone to be an Android device sadly. I really want to want another one. But this experience is starting to sour my taste for them.
I currently run a rooted (virtuous) Dinc. I have gotten the out of space notification many, many times. I have now started to get it again after installing the Google Music app after being invited into the beta. I have removed about 15 programs, but I still only have about 17MB free on that stupid 149MB partition!
This is beyond annoying. If the phone has something like 8GB of internal memory, why can't I use it? Why can't the apps install there? Why limit this massive amount of storage to a measly 150MB? What year is this, 1995?
I know I'm preaching to the choir here, but I am fed up. I don't know what else to do here and I'm ready to walk away. Someone please tell me that Google has saw the light and is going to fix this glaring bug of theirs in Gingerbread or Ice Cream Sandwich!

Why did you create a partition so small? You should create a larger partition to prevent these notifications so often since you'll have more space and use up the extra space not being used. Also, it's not the Android OS's fault that your phone has a small partition made. Since the partition is so small, and you have hardly any memory left (17mb) then it's just one of the phone's functions to notify you about this which should be a good thing to let you know.

Android doesn't just make partitions by itself. Maybe the rom you have did that. try getting a new rom because this is not normal.

Wrong. At least on the HTC Droid Incredible, ROM's have a standard 150 megabyte \data\data partition. For either odexed or deodexed ROM's space is taken in that partition by pretty much every installed application. I've seen contacts hog nearly 70 megabytes of that partition for some handsets, and Sense takes a lot of it, too. Odexed ROM's allegedly require less of the space.
I've run several Froyo ROM's and they all have that limitation. I cannot speak for AOSP ROM's, only Sense ROM's.
There is an app which I have used (but don't seem to be able to find in the Market any more, and the dev isn't responding to PM's here at xda, but I digress) called NotEnoughSpace which allows some portions of the contents to be shifted elsewhere. I found it was very helpful when I was on Froyo, but it does not appear to work on GingerSense. On the other hand, the partition appears to be bigger in GingerSense. The flip side is that the GingerSense ROM's are so fat, there's less RAM available for applications to run.
Pick your poison. I agree it's a stupid limitation that somebody should figure out a way to fix.

Yes, thanks for explaining that much better than I could!
I do have NotEnoughSpace and don't use it for that purpose anymore. I just use it to see how much space I have available and to clean up the dalvik cache. When I was using it to get more space, my apps kept disappearing on me and I would have to re-install them constantly!

is this just a droid problem? i have an epic 4g and it allows me to use the entire 485mb for app storage. what about an apps to sd option? i know at least half of my apps have the option of being stored on the sd card. just wondering.

This does not make any sense. If an app is moved to the SD Card, the space it took up on the device (some if not all) should be gained back since it's not there any longer. Whenever I move an app to the SD Card, I get back my space. There really must be something wrong with your rom/phone.

You sir have alot of apps then.

The small internal Storage is a massive problem. I agree to you.
But I know there are several ways to fix this. What I don't know is how...
There are several ROMs who support different kinds of app2sd scripts so you get more 'virtual' internal storage on the sd card.
As you can see on the pictures attached i have approx. 550 mb free internal storage but more than 40 apps that could be pushed to sd.
To get this it is necessary to re-partition your sd-card and install the correct scripts.
Unfortunately, as i said, i'm not able to tell you exactly how to get this work. I just followed a step-by-step guide somwhere in this forum.
The ROM i use, uses D2SD automatically, if the SD-card is partitioned the right way.
I'm sure you will find something that fits to the ROM you use.

I've used the app2sd and notenoughspace programs in the past, but it seems they have done more harm than good. Apps would stop working. They would disappear completely. The system would crash, etc. I kinda gave up hope on using those approaches.
I was hoping the Google Android team would wake up and just fix this instead of us paying users have to perform work-arounds just to use our devices.

Then you are pretty unlucky. I never had problems with this stuff. All works just fine as it should.
But, of course you are right, i can't understand why they don't give us a GB or so as internal storage either.

Try using a cleaner ROM for your DInc (ie "stock Android"- no Sense UI). I just got a DInc yesterday, switching from an Aria. Did a factory wipe, rooted, and installed the CM7 nightly 100. I believe I currently have s2e on my 8gb MicroSD (just swapped it from my Aria, which had s2e and CM7). Anyway, I have 118MB used, 630MB free internal storage space for apps. This clearly isn't a Google/Android problem. Could be an HTC Sense problem, I suppose.
edit: My Aria even has 185MB available for apps. Not a huge amount, but considering it has a lot less internal space than a DInc, yeah, OP something is wrong.

[Q] Swap, ext2/3/4(?) guide?

Ok first off hope everyone had a great holiday (or Christmas, as the case may be )
I have come to realize that alot of my issues may/may not have been caused by factors outside my phone or the rom I was attempting to install and use. I will give myself credit tho in that in all but one case I have managed to follow instructions to a "T" and have not experienced many/any of the issues that others have. Anyways, I got a new wireless router, and also a class 10 SD card. Some of my earlier connectivity issues are very rare now, and camera issues seem to be minimal also (assuming that the issue there was write speed to the card).
So I've really come to like a few of the roms, in particular one I'm liking right now VERY MUCH is MIUI 1.11.9. What a nicely put together package that is. I would really really like to stay with it.
However, it's huge. With that and two apps (Gmail and Facebook), I'm lucky if I have 14 mb left over. Obviously, this causes crashes and reboots left right and center. Camera usage is almost impossible. But, I'm willing to admit, the problem is likely my fault, because I have not done anything to manipulate swap/ext/etc on my sd card. I have the phone, and I have a formatted 16 gb class 10 sd card.
I've looked through 10 pages of threads and to be honest I'm finding it hard to know where to begin. I'm convinced, however, that if I can learn what swap ext/ext2/ext3 do, and how to create/use them..and whatever else, that MIUI and probably a few of the other roms will be amazing for me.
So is someone bored over the holidays here and can help either point me in the right direction of a Guide to do this, or maybe even write a bit about it for me? Assume I know nothing about how to create a swap, an ext, link2sd, any of it. I don't know how to use terminal emulator, modify or execute scripts...but I can learn!!
I realize that I'm asking for info that is probably obtainable by reading numerous other threads..but I can't find anything truly comphrensive..it's too bad threads couldn't be "stickied"...this subject seems crucial to me in order to get some of these roms to run ok. Many of them operate the same way: they take up 100 mb or so, and they don't allow for easy moving of apps to the SD card.
Anyways many thanks in advance if you can help. I'm sure there's a few others who could probably use a refresher in this also.

I'm learning alot about this and hope to update this thread with my own tips for how to do this in the coming days.
That is, if anyone is interested. If so, hit me with a msg.

internal upgrade?
can someone tell me how to upgrade the internal memory because im getting very low in phone memory.. are there any solutions like using the 1GB for the internal memory of my 8GB card?

Well, you cant physically expand the memory but you can virtually via an extended primary partition and an app like link2sd.

Hey acrobat69
I am pretty much the same boat as you. I have tried a bunch of ROMs, and I am still on 6.3 rc3 now.. went back and tweeked after learning some things and this is the least buggy for me at the moment.
I also do not use swap at the moment.. but this is also something that those in the know here on the Xt720 forums have debated.. how useful is it???
I would love to try swap.. or any other tips you might have.. so I at least will be listening.
I would like to get FM radio working on 6.3 rc3 too.. no luck so far.
I have found that when you overclock.. some speeds and Vsel work better in some roms.. or applications.
I saw one fellow who was running 800/48vsel - overall nice and great for battery usage.. but camera would not work at 48vsel.. would crash it .. running several highpower apps like wifi tether and gps at the same time would crash a low vsel set phone..
SO I know there are many factors that you can tune to make a rom work best for you.
James

When I get back to my PC, ill type something up on this for you as well as archer's other thread similar to this Q.

FYI, FM radio works since 6.3.0 RC4. Well at least as much as FM radio "works" on any of the non-stock-based ROMs at the moment-- volume control is difficult/problematic.
I think 6.3.6 is a good choice if you don't mind disabling the hardware button lights. And if it does bother you, I can make a patch that puts the lights back as the were in RC3 (but would disable notification leds).

Ok so to answer a few of the above questions, I'll try to break it up into sections. Ext2/3/4, Swap and basic memory management.
Ext partitions: since our XT's are so low on memory, a fair while back some scripts were created to make it so that when you downloaded an app, it went into your ext partition and not to the internal. Remember that this was when we had 2.1 and Froyo was only a dream. As you know Froyo has the native App2sd function where you can move most of the app's data/function to your SD card via the .androidsecure folder on your card. Since this was not a function on 2.1 we needed a bypass. This was done by creating a EXT partition on your SDCard to bypass/hijack the installation process and "force" the apps to install to the SDCard rather than the meager internal memory. Since the grand old days, we have evolved that function from app2sd to app2ext where now the /cache can be moved over to the partition as well, in addition to apps like Link2sd with one-click UI to do it for you.
This is how to do it.
1 Make sure your ROM supports app2ext-it should be in that ROMs OP.
2 You need to use GParted or Minitool Partition Wizard to create your Ext2/3 partitions (do not create an Ext4 with either of these b/c they won't work correctly, most ROMs don't support it and you can convert it from 2/3 to 4 in MZ's open recovery).
3 You have a 16gb card and are asking what size should I make my partitions. They need to be in this order-FAT/EXT/SWAP from L->R. FAT is what it sounds like. It is your biggest sized one (and make it Primary/Bootable in your partition wizard). Your Ext is going to be up to you on the size. I usually recommend 350-450mb. Anything bigger is really wasted space. In fact, I chorgle to myself when I see people with 1gb Ext partitions b/c your average size app is usually about 7-12mb (with something like Angry Birds at a meaty 18mb). Remember that 1gb=1024mb. 12mb vs 1024mb-see what I am saying here?
4 So now you have your partitions set up. How do you activate it. You flash your ROM and let it settle down. Get ROOT and open a file manager and go to the ROOT. You will see a folder labeled SD-ext. Open this folder and make another folder called App (not Apps-no S) or if you are using Link2sd, you would put a folder called Link2sd (not LinkS2sd-again no S). Reboot and BAM!!!once it boots up, all your apps that you had will be in there and any new ones will be installed there saving you tons of internal space.
I'll cover Swap tomorrow b/c I am tired of typing for now but here is a thread on some unknown types of memory management that you can do on your own.
Sorry for the long post but I wanted to make it as general as possible so that it wasn't too technical.

Woodrube thank you very much for that, indeed very helpful and to the point. Ill hit you with a thanks when back on my laptop.
James: debates nothwithstanding, I can't see how its possible to install one of these Roms and actually use it...and any decent number of apps with stability, without using the extended partition. I have not had any success until I learned how to do this. Therefore, were absolutely not going to debate it, just do it!
To Woodrubes excellent instructions I will add these tips, learned from Mio7's advice and trial and error:
- do any partitioning before you install your new rom, and do it via a card reader inserted into your computer, not by plugging the phone into the computer via usb.
- do not make the second partition fat. In some threads people said it worked however it never works for me. Create the second partition as ext2 , then go to open recovery and convert it to ext3
- use root explorer to create the folder in sd-ext as Woodrube advised. Make sure root explorer is in R/W mode not R/O or you wont be allowed to
- install Link2sd first of any program. It's when you're running link2sd it seems that you can't create the link for certain applications check the market to see if to the downloadable version then uninstall the app from the phone and reinstall it yourself then when you go back into linksd youll be able to create a link. I'm still experimenting with just how much I can rip out of the system and then reinstall myself so as to be able to move over to the sd card. Btw if the rom app manager wont let you uninstall, use the uninstall function in link2sd. It works, even tho it says "Failed" when done.
See the signature at the bottom of my thread that should be all you need to know about whether not the advice in this thread is good because I'm posting from my phone and I'm using voice to text
Next up I'm going to try installing other roms like MIUI or 7.1 to see you what ones this can be used on. I will post my successes and failures in this thread
