Data2ext?

Hey guys, saw this on front page today. Seems to give a major boost to performance, any chance we could get it working on the hero, but more importantly would it actually help us?

The data to EXT looks to use ext4, I dont think Hero has that capability. Or it does but hasnt been unlocked so to speak. There is a data2sd that uses ext2, and still provides a 250% increase in I/O, if I was reading correctly. I am gonna look into this today. We need to start with Deca, the kernel needs to be able to allow a few things for it to work.

didn't we have ext4 in some of the older 2.1 roms, like DarchDroid? I wish Darch would come out of hiding

The OP was updated and it says the the mod is stable and faster on ext2
I havent tried it yet, I did chat with firerat a bit and he says it wont interfere with his Mod, and it should work. He gave me a busybox code that is supposed to do the same thing BUT when reboot the code is lost and would need to be entered again. I tried it and got no high scores on benchmark, still pulling 450.
Code:
busybox mount -o noatime,nodiratime,remount /data

Oh wow, well when I get a chance I'll try it out. I don't use firerat's mod so maybe something weird is interfering :/

Maybe should go on twitter and ask him I guess since he was so sincere about it, he probably doesn't think that hack should be used at least not for the average user I guess. I mean he said "you've been warned" lol so I think ill roll with his advice. Good luck to you all who use it.

Any form of an Apps2SD won't get you support, unless you are using the Froyo version.
I'm going to check it out. Maybe some of the ideas behind the code can be used to resolve some of Darktremor's quirks.

No, he doesn't like anything that remotely looks like his old Apps2SD code. He thinks they create the stability issues with CM. I can't vouch for that, but I have a lot of people who run Apps2SD-style code on their CM with no issues.

quick update
looks like one of the gsm devs has a working data2ext cooked into his rom.
currently it's still in the early stages so it's kinda unstable, however, looking at the quadrant scores they are pushing their phones into the low 700 range...

I think it is just not for average user issue. I went though the whole process on my Hero and made a mistake. I used a program called EASEUS to create my partitions on SD, I set them all as Logical so when I rebooted the phone saw no card to mount Had to format card, restore my data, so I could nandroid back. Then I had to.. well, lets just say it was a pain in the arse for such a dumb mistake! LOL Try again tomorrow, on a spare sdcard.

Can't you just make partitions from the recovery menu?

I dont have that option on clockwork, I can create partition from the app, but the mod directions say to use a program called Gparted, or Fdsk. I just tried it again with a smaller sd card, class 2, and it didnt work again. Something has to give, they are doing this on the G1, N1, Desire, come on Devs lets rock this on out Hero's!!!

I might give it a shot if i have time tonight, but I'm no dev so don't expect magic has anyone bounced this idea to deca or aosp?
Sent from my HERO200 using XDA App

ooh crap, i tried flashing amon_ra's custom recovery to make partitions.. for some reason it jacked up EVERYTHING. just spent 30 minutes getting my phone to boot/boot into recovery without freezing
edit: and spent the 30 minutes reflashing a rom and resetting everything... this better work
YET ANOTHER update: i am teh fail and am a linux noob. so i couldn't get it to work last night but managed to not brick my phone. good news is i contacted a very talented dev and he said he's already working on it

Any luck? I didnt try at all today. Gonna look into the darltremor script though, it already moves dalvik to ext/sd so it wouldnt take much more, maybe tweak that code from firerat....
EDIT.......
These scripts are popping up in flashable form now! I flashed one that may work BUT it needs 3 ext partitions. I flashed with only 1 ext and it booted but was SLOW. Gonna try later with correct partitions. I also found one were someone took the darktremor apps2sd and modified it to include data, gonna flash that now!

I flashed a modded darltremor app2sd and ran a quadrant. It flew through I/O test 1 and 2 but then hangs on database writes. So it IS close and CAN work on Hero!!!!

[Q] 4 GB internal memory

Hi,
I am going to get this phone shortly. Can someone please answer the following questions for me.
I have come to know that although the phone has 4 GB of internal memory only 1 GB is usable. Does this change when I install a custom rom (e.g. CM7). Can I then utilize all the space?
Another question. Does skype (video calling) work ok?
Thanks

The phone only has 1gb of internal memory, and when you install any rom, it uses some of that internal memory to store itself.

This says otherwise http://www.gsmarena.com/t_mobile_mytouch_4g-3520.php

It has 4 gb of internal memory, but you can't touch all but 1. You can't even see it. So as far as anyone is concerned, it has 1gb.

I'm not so sure because a Rom doesn't take up 3gbs. So the site may just have false info.
Sent from my HTC Glacier using XDA Premium App

doesn't matter how much internal storage it has, 1gb is used by the system, so it must have 1gb. whats the point of having 3gb that nothing can use. It's gotta be mis-stated specs.

I'm not always right. However, this time I'm pretty sure I am. There is only 1gb of storage for you, the system, or anything else. If you found a website that says otherwise, its wrong.

PC Mag confirms 1gb memory. Think the g2 is the one that is screwy like that with the 4gb onboard memory, but only 1 is usable.

This link will likely answer all of your questions. Basically it is 4GB in specification, but utilized in such a way as to have only 2GB available. Of that, some is used by the ROM itself for /system, /cache, etc, leaving us with about 1GB. FYI that site has a lot of useful information that applies to the Glacier even though he is specifically talking about the Vision. Very similar devices.
Also, I personally think it is a bit shady to advertise it as 4GB, when in fact it is actually 2GB. That's like advertising an engine as 300hp, when in effect it only has 150hp in your particular implementation. Just because the engine is actually capable, in some form, of putting out 300hp...lol Rough analogy, I know, but you get the point. Basically they really should advertise as 2GB.

Hi,
From what I've learned since yesterday the mytouch 4g actually has a 4 GB rom chip but only 1 GB is usable (same problem as the G2). The following link describes this in detail.
http://forum.xda-developers.com/wiki/index.php?title=HTC_Vision#The_Missing_2GB
The PC Magazine has 'as tested' written in front of 'internal memory' so its an observation they've made. Not official specs. Official specs for MT 4g state that it has 4 GB rom
http://www.htc.com/us/products/t-mobile-mytouch-4g#tech-specs
Regards,
Ali Kazmi

Good link Ali. Thanks. That puts the information in more layman's terms. So I think the answer to the question of whether or not it actually has 4GB is "well, it does...but it doesn't"

Dualbooting

Can you dualboot miui and cm7?

For what reason would you want to do that?
I'm guessing if you know how to dual-boot then try it make sure you have a kernel that's compatible with both.. otherwise no.

Because I like them both and can't decide which I want as my daily.
With the new partition map and both roms under 118 mb I don't see why we can't have 2 different roms on the internal memory.
I am trying to find a computer science summer school so I can do this myself but summer is far away so I was wondering if any of our amazing devs could do that quicker than me

Possible the how to dual boot in android development .....
I think this method still works very lenghty so read up :

Sent From My "epic" SPH-D700 via XDA Premium

But that requires me to boot from the sd card which is really slow.
I think this is going to be my first real project.
It doesn't seem complicated.
I tried at other projects and failed so I'm going to give this a shot and if it works I'll post it in the development section.

Yes, one would need to boot from the sd card because there is no current way to share the system and data space. Your phone would not be able to seperate one framework-res from the other...you get the idea. You can't put pot roast and spaghetti in the same pot and try to eat only pot roast.
Sent from my SPH-D700 using XDA App

But if you make 2 system folders and 2 data folders and interrupt he boot path to let you choose which ones to use it might be possible. Take all that I am saying with a grain of salt but our device has done some pretty amazing things the past year and a half so let's let it live up to it's name and try every single way to make it better. I am going to start trying after I get my spring break because I'm a freshman in high school then in the summer after my classes I could probably get close or a buggy version working. I just needed to know if any other developer already did it so I wouldn't waste my time.
Sent from my SPH-D700 using XDA App

It sounds more like it would need 2 partitions and some controller to pick which one at boot up but feasible since computers can do it.

What do you mean by dual boot?
http://epiccm.blogspot.com/2012/01/boot-el30-stock-from-sdcard.html
The temporary EL30 boot from sdcard is a method of "dual boot" which has been useful for people to update PRL and calibrate sensors. This old version is problematic in that 3G and 4G data is broken. We know how to fix it, but it would take a few hours of work and there hasn't been demand for it.
Any type of dual boot would boot from the sdcard. The slow sdcard. Not a great user experience.

LOL...I got a quad boot on my phone. If I boot right into CWM I have nandroids of 4 ROMs to choose from to restore. Takes less than 10 minutes to restore one and then there is no issue of running from a slow sd card since we don't have enough internal memory to make real dual boot work.

Nook color has this. Although I never compared the specs. One boots off SD card, thither off internal memory. Speed off SD is same as internal. But I don't think the epic could handle this as a full time option. Just my opinion. My NC dual boots cm7 and cm9.

Where'd all that space come from? I thought we only had like 300 megs in both RAM and ROM?
Also my friends tp2 and hd2 dual booted very easily into android (infact I think the hd2 is the most developed for android phone after the g1 and nexus 1, and its not even native lololol) and ran extremely smooth (on the hd2...on the tp2 it was like a hero with a keyboard lol. Random sluggishness.)
But nah if the hd2 can handle it I know damn well our phones can handle it. The problem is, everything we can dual boot is closed source so that's why windows phones can dual boot android but not vice-versa (I mean, you could do it yourself but just can't distribute it).
Meego seems like a great choice for a dual boot though since its open source and amazing...

Whats funny is the HTC HD2 still runs ICS or can dual boot etc... and its 3 years old

I have had my head spun by this topic myself -- I've been doing a lot of searches and reading just about every result but I can't seem to find good general info on the subject. I've seen some loosely compiled info on dual booting CM9/CM7, and I've seen some info on the EL30 from sdcard mentioned before, but I had hoped to boot CM9/CleanGB as CleanGB is what I'm running stable and comfortable with now. I'd just like to be able to have stable and comfortable as a fallback for playing with ICS. I know running off the sd is supposed to be quite slow, I don't really know what to expect as to HOW slow, but the way I figured slow was an acceptable compromise for a stable fallback.
My bottom line has been that a lot of kernels seem to support this, yet it feels like there's very little info on doing it, and that just confuses me a skosh. Is CM9/CleanGB even possible due to kernel requirements?

The rom is only that size zipped up. While CM and AOSP based roms are smaller then stock based roms generally there will always be a good bit of space taken up by the OS.

Thanks, 8gb of space used though? Just curiosity for the most part.
