Ext4

K I'm tired of stock dk28 and I wanna flash a rom but they all seem to need ext4...
does ext4 format anything? What's the benefit besides "speed increase" because I'm satisfied with the speed of the phone already
I remember I had to format my sdcard to ext4 in Amon_RA and I hope its not gonna do that again lol

It formats the internal memory of the phone to EXT4. Speed increase is not immense like some are saying.

You don't have to have EXT4 for all of the Froyo roms. I think its a little confusing to some people because most of the Froyo roms support EXT4 not Require it. For instance, Bonsai4all 1.1.3 supports EXT4 but doesn't require it. That is a nice rom if you want to try it out.

I gotta say I'm having a different experience with EXT4. I have noticed that Angry Birds stutters now and again and so does the music. Maybe something else is wrong, dunno. I am running the apps off of the SD card but I was also using RFS.

Your system files are copied to the sdcard temporarily, the internal memory is formatted ext4, and then the data is copied back. Unless there's a problem, you won't lose any data.
Additionally, all the ROMs that use Dameon's kernel and are listed as EXT4/RFS or "dual"(Bonsai, Nebula, Quantum) will boot whether the file system is EXT4 or RFS.

I'm having intermittent stuttering as well.

For me, ext4 has been a disappointment. I'm keeping it for now, but I haven't noticed any improvements, and if given the option of doing it again, I wouldn't bother at this point. As said above, lots of 2.2 ROMs don't require ext4, and I can't give you a reason to convert to it.

I am seing the best battery life with ext 4 since I've had froyo. Without ext 4 on froyo I was getting 20 maybe 30 hours on charge if I was lucky now with ext 4 I'm getting 48 - 55 hours. Sweeet I noticed a lil stutterng during games but boot is way faster.

I was incredibly curious to try the Bonsai ROM, but I've been away from the forums for a while and missed the big hooplah over EXT4 so I know very little about it. I'm not all that interested though, and the developer's install guide specifically goes through the steps to format to EXT4 and doesn't mention it being optional and there's not a lot of info about it on the Wiki.
So I could just grab it, flash it like I would any other ROM on any other phone and be fine then? And does anyone know if I would flash the extra thing he describes in his install guide? There's no indication on whether its for EXT4 only or not.

Rom manager or flashin not working
My epic never allowed flashing of roms through rom manager or maybe im doing it wrong but i have always used odin to load dk28 or back to stock dk18..does anyone know where i can get the .md5 or .tar files of any rom out there so i can load it with odin or maybe im just ass backwards and dont know what im doing?? lol not a newb but farely new to android community

You wouldn't do it through rom manager (which is when you're booted), you would do it through clockwork mod (which is a part of rom manager). Hold camera, down volume, and power when phone is off and keep holding till you boot into recovery. (I'm sorry if I'm assuming you don't know this but when ppl say they use rom manager I don't know if they know your supposed to use recovery mode)

dudes i am planning to switch to #199 cm7.
the plans are...
1) fresh flash #199 with 2.6.32 buzz kernal.
2) dta2sd beta 3,jewz ram script, sd speed increase script(4068) .
3) custom mtd partition with 170mb system and 30 mb cache.
4) data and app to sd ext4.
5) 8gb class 4 sd partitioned to 1gb ext4, 32mb swap, rest with fat32 with a large allocation value.
6) lot of paid app of course.
i need your suggestions ....
thanks in advance.

Do the mtd partition as you install 199, I got problems when a2sd was already installed, my mtd settings are 140 10, 10mb works fine for cache just make sure you have 06mountdl in your init.d folder otherwise you wont be able to download anything from the market above 10mb in size, if it isn't in the init.d folder you should find it in the cm zip.

dude i haven't heared of init.d folder. pls explain. well i surely plan to give 25 mb cache. if so do i need to care about init.d folder?
" just make sure you have 06mountdl in your init.d folder" dude i realy dont understand this.
" if it isn't in the init.d folder you should find it in the cm zip." and this too i dnt understand.
so i am a newbee to custom mtd partition. hence i need help about this. how should i need to use the script? i plan to flash it soon after i reboot to #199. only after that i will install my apps.and also gapps. so do i need to take nandroid backup? as i have backups of my app using titanium backup. so i will install every thing later.

Put the files needed on your sd card and write your settings in the txt file.
Run the first part of the mtd partition (wipe system/data/cache and install the first zip, bravo recovery or something like that, reboot your recovery from the advanced setting.
After doing the first step install your fresh copy of cm7 (instead of the nandroid backup) without wiping anything, then run the bravo boot zip and let it boot before installing anything else.
Files from the market, when first downloaded go to your /cache folder which if set to only 10mb would mean you can only download files below 10mb in size, the 06mountdl script deals with this by diverting the downloads elsewhere /data partition I think (not sure), the scripts are found in /system/etc/init.d after installing cyanogen if your cache size is small just check that folder (with root explorer) as a few times I have had to extract 06mountdl from the cm7 zip because it hasn't installed.
All that happens if 06mountdl isn't there is, when you go to the market you'll get an annoying message saying you don't have space left if the filesize of the app is larger than your cache.
Hope that made sense its 7am here.

thanks for your help dude. i will check it out. also do i need to flash dta2sd b4 or after i install apps. i had done it b4 i install apps in my current rom#177. do you have any suggestions?
Sent from my HTC Wildfire using XDA App

Not entirely sure, I know some people say before but its never harmed me doing it after, you may aswell just run it straightaway though after your first reboot. Just in case.
I only use beta 3 as I had problems with beta 4, I don't think there's any noticeable changes between them tbh.

So i ended up in cm7#203. Stable. Fast, like it a lot.
The sad thing is i can't make custom mtd. Every time i ended in a non booting cm7 boot screen. Actually i had to flash froyo 2.2.1 ruu 2 times. Rooted, installed cwm. 2 times. Coz i had done like u said. Flashed custom mtd recovery with mtdpartmap.txt file containing 160 25. Then installed new rom with a reboot of recovery only.also flashed bravo boot. All as you said. Stuck in splash screen. So again tried to flash new rom and kernel from recovery. Still the same after flashing. So again ruu flash. Install custom cwm v5.xxx.partitioned SD. This time the SD got corrupted. So removed custom cwm and put original cwm using fastboot flash. Then partitioned with out errors. And installed cm7#203 from cwm, SD speed increase script,Jews ram script,2.6.35 kernal, latest radio, mediaprofile patch, gapps for 2.3.5 Andy. Rebooted after dalvic wipe. Itz running perfect. Installed s2e app . Moved app,private app, data, to ext.
I think that s2e is more efficient than dta2sd. It is faster, move almost every thing to ext. And internal memory consumption is quite low after app installations(when compared to dta2sd). Also booting and shut down are faster.
I will be watching for future errors. Thank you.

Nand problem

Hi
During more than year of my "android on hd2 experience" I've had no problems at all. To be honest i became quite handy on this field.
recently I was using two roms daily HyperDroid-CM7 and testing NexusHD2-IceCreamSandwich Beta.
on NexusHD2 rom i install Data2SDInstaller.
and my problem started when I wanted to go back to HyperDroid.
boot animation stuck, of course i tried clk / magdlr different partition sizes always task29...without any effects. Now I tried NexusHD2 ICS 4.0.3 CM9 V1.0 , finally went through boot animation,when i saw Setup Wizard the messages appear immediately: "Unfortunetly, the process ....... has stopped" and when I click OK appears next and the next message , such as contacts, Email, calendar, etc. i thing all of the possible .. later message: Setup Wizard not responding.
And it happens on magdlr/300/5
I've read already about bad NAND blocks, and in recovery.log I did not detect any of them
I tried to run MTTY but I have a problem with drivers win7x64: - /
Does anyone know what's wrong with my HD2 and how to solve it.

you remembered to wipe the sd-ext partition and .android folder (cwm - wipe data / factory reset) right?
there are folders on both sd-ext and on the fat32 partition that will screw with new installs.

Like he said, you need to wipe your sd card, ext and fat32. Both parts. This is majorly important since you used Apps 2SD!!
Another thing, I think your system size is way off. 200/5 for cLK if not 180/5 and for magldr probably like 200/44 but at least 10mb of cache..

I'm not too sure if this will help or not but this is my experience.
I have been on these forums for a while and using Hyperdroid for quite some time now as well. The reason why I do not have any posts on this account is because I switched over just today, my old account was imarte068.
When trying to update my Hyperdroid the other day through magdlr I encountered an issue. No matter the partition size or sd-card, it always managed to get stuck on boot. I got frustrated and attempted to re-flash countless times. After many attempts I gave up and just used an MIUI rom.
Several days later I devoted myself to solving the issue. After about an hour or so of trial and error I fixed it. I simply re-flashed the kernel after the installation of the rom. I am using magdlr therefore I do not know if the process will be the same for clk.
Hope I could be of help.

I thought it was a sdcard and i delete all partition and make it new.
I do always full wipe and dalvic...

Try re-flashing the kernel as I said in the post above.
Link to kernel here.
Hope I could be of help.

This may spur some argument, but in my experience task 29 is the key if you're having problems. many people say wipe with cwm the system boot davlik cache, etc but in my testing when I'm having a problem and need to solve it task 29 has been the answer almost everytime. Partition size is huge as well. Another thing if you were using apps2 SD on ics it was bugged. Without formatting your SD it is possible that it could bug your system.

Im using 220 with 5mb cache. ICS running smooth without any problems. And no need to fully wipe sdcard. Would be stupid to delete the whole card just for flashing a new rom hehe. Its enough to wipe the (dalvik) cache and sd-ext partition via CWM.
For data2sd use the 'how to' from post #207 and the flashable file from post #174 in tytungs ics cm9 v1 thread. I think it removes old app2sd or data2sd scripts. Worked without any formatting of my sdcard.. works like a charm.
Btw.. ever tried to fix permissions? First thing you should try if you get FC.
Just do (re)install the rom like the guy in post #207 described but with the file from #174 (40ad2sdx-a2Recovery.zip)
And im using my hd2 now for more then one year. NEVER used task29.

Edit: btw for problems with your Usb? Driver on win7 machines try to install new version of WMDC (windows mobile device center)
Solved the problem for a friend

As I said people will disagree. I will say that in most cases you're right though, wiping the davlik cache is enough. I am just saying from my personal experience there are sometimes when it isn't (at least on my phone). I'm not trying to start an argument, I just want to help him.

big thanks mates for advice.
So far I haven't had time for it but for sure tomorrow or on the weekend, I will deal with this and I will let you know how it goes.

In brief I run ICS all fine, but HyperDroid not starting.
Here is how i try:
________
Ok I was using WP7 and whats I made:
SD card: I delete all partition, I make only one Fat32 than in CWM I made ext partition.
Task29 > Clk 200/5 > recovery > install HyperDroid-CM7-v5.7.0 > And here phone stuck before boot animation, only white android robo > then as flamgodian advice I install kernel thins. > Same without boot animation.
Second try
Task29>clk 220/5>recovery>wipe(all possible)>install HyperDroid-CM7-v5.7.0>same robo>fix permision> install kernel this> I saw robo for 10s and phone self reboot after reboot > stuck :/
I have not seen even the boot animation.
Task29>clk 220/5>recovery>wipe(all possible)>install NexusHD2-ICS-CM9>Kernel>
He goes
__
I make like redplate(Big Thanks) write with installation 40ad2sdx, and everything runs great.
I will stay with ICS but it is strange why my phone doesn't like HyperDroid Rom.
And from here I would like to thank you all for advice.

Phone wont boot after enabling zram

I finally got my stuff copied to my 4gb sd card. However, after installing Dorimanx Kernel 5.7 with my initrd.gz file, it wont boot at all. What am i doing wrong?
I used Linux Disk utility to create a linux swap partition.
My ROM is Hyperdroid 5.10.22
Thanks to everyone!

Yes i did. then i used Ubuntu, to get rid of the sd-ext partition as i do not want one but apparantly you must have one.
UPDATE: i got it working but now i cant restore my ****ing data back to my device. It just hangs again. This is really pissing me off..

****!! Might have something to do with sdext partition, like a script that just found it..
use fikret kernel

Well i went back to my 2GB card, without the partitions. And redid everything. Now im trying this using my 4GB card.. Hoping to god it works. However, when i ran quadrant with zram installed. I didnt get any better of a reading then before. Which i should have since i have zram on.
EDIT: Well that didnt do ****. It booted but it says i have 92MB free space. I think im going back and just using it without zram. i was hoping zram would make things load faster and make it overall faster but **** all this **** lol

Yeah zram didn't help me. I'm not sure if I installed it incorrectly or something but I saw literally no difference when I flashed it. Also, didn't you at least make a CWM or Titanium Backup backup before flashing?

Yeah i did, but after enabling zram and SD-ext data, i tried restoring my data from the CWM img. But then it wouldnt even boot. So now i actually just switched to dorimanx ROM and i have sd-ext which is working properly, but again my benchmark isnt much different. I really would like to know how people get such high benchmarks. I know its only the I/O that makes these high benchmarks but a high I/O is actually good when it comes to playing games. It can read the data much faster.

Problem with internal memory on froyo JPU

Hey friends,,
I've lately facing a problem with my galaxy 3. Lately i've been using custom ROM's based on JPU and the internal memory is getting low too quickly. It's like the apps take the double of its real size, so i can't have even more than 15 apps that my internal memory is already gone...
To realize if it's the custom ROM or not, I've tried the original froyo version I5800XXJPU and have got the same problem. Initially the total free memory was 170mb, after the system updates (gmail, market, google search...) it decreased to 130mb, and after just installing the facebook and facebook messenger it's about to 100mb
I don't use Hybrid Data2sd, because i simply don't like it and had some problems with it last time. And yes, i move the apps to the sd card in the own system interface.
Am I doing something wrong? Someone knows how to solve it?

The dalvik cache is probably taking up a lot of memory. Just wipe the dalvik cache and cache in recovery and you should get maybe 10 extra MB or so.

check your internal and external memory for .exe file virus with esfile explorer

One simple thing - DEODEX
When you deodex the dalvik cache goes to /data for /system/app and ../framework also.. I am on ODEX and it's good enough.. PS - You need to odex manually or download a pure stock ROM or some odexed custom ROM..
IF THIS IS NOT THE PROBLEM PLEASE CONTACT ME or SOMEONE ELSE WHO CAN HELP
