NAND or EXT2:which you you like most? - Tilt, TyTN II, MDA Vario III Android Development

And why?
I find that ext2 isn't slower (yet) than using NAND.
I've installed to NAND because it's faster boot (first windows than android).
Since GPS is stable and faster than on win. mobile I have finally made the switch.

Ext3 vs ext4

Hello to all.
I have a question:what is the differences between the two file system in object of this thread?
I read that some Roms support ext4 and now I have ext3.
I need to change this?is better for performance?
Thanks

I would like to know this also
Ext4 is the newer Linux file system. Much like Windows 95 moved to Fat32, Vista moved to the NT file system. Linux is now moving to version 4 of their file system. The new file system is more efficient, has journaling and is more secure. It really will not have any noticeable affect on operation.
It must be noted though that native Linux file systems are a lot faster than Fat Windows file systems, however they are not accessible when you put your SD card into a Windows computer. This is why only part of the card is partitioned to Ext3/4 along with the benefit of not having to unmount a file system with your apps on it.

I ve read a post with a very good explanation a week ago .
I will search !
Edit : hum sorry its about a2sd+ , but a little about ext3 and ext4
http://forum.xda-developers.com/showpost.php?p=7458565&postcount=8
So it's not really important to make the upgrade to ext4 for me?it's only a problem about security and not affect the performance?

i think it doesnt matter on a sd card which ext you use
sdcards are too slow
Check out this article for extensive info.
It is increased journalisation, and better handling of bigger volumes/files.
All the above is absolutely right, but totally wrong. The technical aspects are not important here. For the HTC Desire user the main difference between those filesystems is simple: stock kernel and recovery does not support ext4. That's it.
If you never plan to use stock kernel and/or recovery or skiled enough to enable ext4 support for them, then go ahead and read all those technical articles and do (or do not) change the FS type. If the words "stock kernel" and "stock recovery" mean nothing to you at the moment, you better stick to ext3.
P.S. in theory, ext4 gives you better write performance (and slightly longer SD card life) only if you frequently write the data to the ext partition. But this is not the case for A2SD partition, where the apps are installed occasionally. Unless you plan to give the Desire or the SD card to your grandchildren after many-many years.

[Q] NAND memory write cycles (life expectancy)?

Just wondering with all these reflashes of ROM we are doing, how long will internal NAND last before it's dead?
it will last long enough. It's the same flash type used in Solid State Discs, running Windows or Linux, so yeah, you can flash your ROM at least 100.000 times. More like 1 million time.
They should had still given us 2GB for internal NAND,then we wouldn't have to do the a2sd+ etc...

Your Sense HD rom experience?

Hi guys I have no intention of starting a flame war regarding who has the best sense hd rom. I just want to know from people who switch a lot which one is really the best in terms of everyday use.
I have tried most of them but I just came to the conclusion that they are all the same, which is somewhat slow and incomplete. Perhaps someone with more experience can share? All of the rom claim to be stable and fast, others "fastest" even and I wanna know whats it like beyond the label. Coming from an HD rom and going back to a regular froyo sense rom is a totally different experience, the speed difference can clearly be seen and my only wish is that one day the desire can handle the HD rom just as fast.
Please share your inputs guys, preciate it!
I noticed a slight speed difference between those HD Roms ...
coming from LeeDroid 2.2f i switched to Aurax T Sense which felt a bit slow after a while. Then i tried RCMixHD which also became a little laggy after one week.
especially the pulldown menu and transition animations were really laggy so i switched to baadnwz 1.3 HD rom.
with my 768 MB ext 4 partition on class 4 microSD the baadnwz rom feels quite good after a while. speed differences to standard froyo Sense Roms are barely noticeable ... even with applying tons of skins, font changes and transition animations to it.

I also agree. Having flashed every hd rom, I find baadnwz 1.3 to be the fastest, smoothest and most stable Rom. I think this is to do with installing everything to nand. All this on a class 2 microsd. I have ordered a 16gb class 4 microsd so can't wait to try it out.

Im sorry I am a noob at this and I need help interpreting this:
ext2/3/4 partition AFTER the fat32 one
All I know to do is to create an ext 2 partition with rom manager, I have no idea what ext 3/4 and the fat32 one is
Is there an easier way to create a 1gb extension ? Rom manager can only do up to 512mb
thanks!

EXT is the extended filesystem used by Linux. Fat32 is the File Allocation Table (32bit) used by windows.
Power down your device hold down volume down, and the power button until bootloader shows, use the select Recovery using the power button and volume up and down. If you have ClockwordMod Recovery v2.5.1.3 installed you can go to advanced and select 'partition SD card'. From there you can choose 128, 256, 512, 1024, 2048 or 4096 Mbs.
*Edit* Use a zero swap size. It will format the partion to EXT3 which is ideal.
Ignore that last post, I was thinking of the wrong ClockworkMod it's the DHD's one.
You'll need to download ClockworkMod Recovery 2.5.1.8 from here put it into your SDK folder, by default it's C:\AndroidSDK\Tools. Plug your phone into the PC open up Command prompt, and type 'fastboot flash recovery recovery-clockwork-2.5.1.8-bravo.img' press enter and it should take two seconds then it will be done.
From there you can power down your device hold down volume down, and the power button until bootloader shows, use the select Recovery using the power button and volume up and down. Go to advanced and select 'partition SD card'. From there you can choose 128, 256, 512, 1024, 2048 or 4096 Mbs. And again use a zero swap size.

But whats the difference between ext 2 / 3 / 4 ? and which one do i need for the dhd rom? ext 2 right?

I don't see why 2 wouldn't work, but we use 3. I know four works, not too sure about two, just stick with ext3.
*Edit* Not that Recovery actually gives you a choice, it will automatically format the partition as EXT3.
Why isn't the latest build of clockwork showing up on rom manager?
I downloaded the file and I am getting signature verification failed when trying to install it. It's the only thing thats stopping me (
Wait, from what I understand ext 2/3/4 is like making 3 different partitions in your sd card for your data to be stored right? So data is equally distributed among the 3?
Preciate the help

I don't know why the latest build isn't showing up, are you following my instructions and using ADB (Android Debug Bridge) to install the .img file via Command Prompt?
i tried all hd roms, yes i agree all are same no doubt about that (all roms are same except a few things like theme) and yes the hd roms are laggy here and there. i m back to leedroid, by far the most stable rom i love it. earlier was on pays rom, but its not updated lately so... leedroid rocks
MY experience was bad. 6 hours of battery life (a day with the latest leedroid), laggy, although I miss the DHD goodies
Try ReflexHD Sense by Ne0phyte, latest 1.5 version is insanely smooth! I feel like I'm using my wife's Desire HD, only smaller screen! I left 1.4.1 version because of the already mentioned lags here and there, but now they're all gone. I repeat, this is actually HD experience on regular Desire, and I say that because it performs just like a (stock) HD handset as I tried that thoroughly. And I noticed there's a 1.5.1 already
I have tried too almost all of the HD roms, I like them, now using baadnwz, but the battery life is still terrible. 40% remaining after 9 hours unplugged. With my the Alex-V rom I had no problem pulling 24+ hours on one charge with same usage.
sense PFF... its not my taste, but i tried a few just try these new "HD" roms. the one i found best was RCMixHD with DATA2EXT. i got 2,2k Quadrant points, and the speed is amazing, i am using 1190mhz OC... but still, its ultra smooth with launcherpro plus with 3D drawer if i find a way to change the lame statusbar i might be on this rom
I tried almost all Sense HD available. Frankly speaking, don't feel they can be used daily. always found it laggy especially using live wallpaper. Back to MIUI rom. The best ever till now.

[Q] Most stable build?

So i have used different ROMs and love android on my kaiser.
However, after a few days use the phone tends to crash and afterwards loses all data(SMS etc) and/or apps. The 2.6.32 kernel seems to be better but this still happens.
So is there a way for this to not happen? I'm currently just restoring data to avoid reinstallign apps and using backup apps to restore SMS etc.
Is this to do with data being on NAND? and if so is there no data loss on SD card but is it slower and can you not remove SD card if you do it that way?
i'm searching that too but i have a big problem with all android roms..
my problem : i can turn on the wi-fi and it shows me the wifi networks... BUT after i pressed on my network and entered my password correctly it says disconnected...
what can i do ? please help me it makes me angry
anyone? i'm sure someone knows what's going on!

From my understanding the older kernel 2.6.25 is more stable, although it lacks some of the updates that later versions provide.
Installing system to NAND and data to storage card is no doubt the most nonvolatile option at this point. It can run a bit slower, but this can be circumvented by overclocking the CPU using RogueTools (a bit taxing on the battery, however).
It's always a good idea to keep consistent backups made to insure your data is safe. You can never go wrong there. Just be sure you have the latest patch of the current version you've flashed, do a clean system install, add your usual apps, reboot to the boot menu and backup data, then restore data from the same menu. This has been the recommended process mentioned in other threads.
this also happens to me, for a few days everything runs fine, however once in a while (about 2 days) system crashs and i have to restore data (with every apps installed). The problem is that all sms, call log, and some apps settings are wiped.. =( that's not cool ;P
another problem is everytime i reboot, or restore data, 3g is enabled... even if i put on settings "no data". is pain in the ass when my data plan limited exceeds, every time i reboot, carrier charges me more money... any solution? thanks in advance...
You can disable data on boot in the kernel, either in Atools or change ppp.nostart=0 to ppp.nostart=1 with a hex editor. I think the only way to enable data then is with Modem.apk, but most builds have it and if not, you can just copy it from a similar build.
I used it like this for quite a while when I was on a contract with no data plan.

could you possibly point me in the direction of guide for how to put data on storage card? i'm currently using it on NAND and it dies after a few days.

you have to split your SD into three primary partitions: FAT32, EXT2 and one more EXT2. Use something like Partition magic or free EASEUS Partition Master to do that.
REMEMBER: all partitions should be Primary, not Logical. FAT32 must go first, or your Windows PC won't detect it.
first is acessible from Windows and is used for storing music, pictures and other stuff. You also place andboot folder to that partition.
second and third are for /data and /swap respectively. /data will contain all your apps, so don't be greedy with its capacity, and /swap is a location for temporary data, so 256 Megabytes are enough.
AFTER YOUR SD IS SPLIT, use atools to assign data and swap to appropriate partitions (SD partition 2 and 3), then flash your Kaiser with such an NBH.
FINALLY, boot up from sd card with Android build in andboot folder, hold the D-pad center for installation menu and select "data to SD partition" option.
Let the installation complete and press Quit to boot into your crashproof Droid.
For me, the MOST MOST MOST stable build were Warbyte's Donut and Myn's Warm Donuts.
Froyo crashes pretty random at bootups due to init.rc corruption. If you want to be handy with android OS and don't messa round alot, I suggest you go with Donut. Froyo does offer you performance but in my opinion its less stable than a usual Donut build with 2.6.25

so youre saying if i do like You said I can reboot as many times as i want and nothong would wipe? and btw. if i use atools to mod boot settings my kaiser freezes when running quadrant benchmark or raging thunder.

Majority of Developers start building for Donut first since its still primary OS for alot of devices. So far all of the apps worked on Donut for me. ADW, Handful of Widgets, Documents2Go, FruitNinja, and blablabla apps.
Flashplayer doesn't work even on foryo as of yet

Just a correction, to my understanding, 2nd Partition is there for Sys on SD Card Partition, and 3rd Partition is there for Data on SD Card Partition option. If you make a 4th partition with linux swap FS, it will be auto-mounted at startup

Never liked Zeam Launcher, it's just a dumbed down version of ADW in my opinion. But I will agree with the newest Gmail. Hell it's not even supported in Eclair. >_<
Donut is by far the best as it's designed for phones the same age as our Kaiser's, and Eclair would be considered an upgrade option for our phones as well. Froyo on the other hand as well as Gingerbread would be "unofficial" upgrades as they would be too resource hungry for our small devices.
Zeam is pretty snappy but Helix launcher is okay on donut otherwise. Twitter, oh well, there are dozen of apps that tweet for you on your donut. Gmail, I agree. and soundhound, never used it >.<
Eclair isnt as snappy as froyo or donut but worths if software support it. I say that try thoughtlesskyle's Not So Super Froyo or mine build as well. Considering init.rc, its more obvious in updated versions of fresh froyos (usually happens if you reboot with some resource taking process running)
i cannot install a donut release. but the froyo works installing.
I don't know why. any suggestions?
hey,
so i'm using data in a partition on my microsd card and so far is pretty crash proof. unfortunately it's only a class2 one, and so it can be slow and some apps like alarm doesn't work properly, i suspect this is due to the slow microsd card.
Is there a difference in speed between using a partition and using data.img without a partition?
Will using a class 4/6 one solve this problem? getting very close to a stable phone that does all i want!

[Q] D2ext versus D2W

So whats the difference then?
I know that data to ext means that their has to be a particular partition structure and data 2 wherever does what it sounds ie it uses "wherever" it finds, but why would you choose one over the other? Is one faster? more secure? Why wouldn't I just use the D2W rom simply on the basis that it is less complicated?
Yes I was also searching the difference since some time now. Lots of ROM offers 3 types.
A2SD - Which I understand and using it
what is D2W an D2EXT? what are the benefits?
Ok, from release notes on some roms I understand that D2W is actually faster. But there is the chance of losing some data using this method, D2ext is supposedly more secure.
Is this even nearly right?
And what is the second ext partition actually for?
It's nearly the same. With d2w, the partionning and formatting is done automaticly (the 2nd partition must exists). with d2e, you have to format the 2nd partition (using gparted for examples)
