OOO yes this is great app!

i forgot about it!

i have used it and realized that all my neighbors sitting on the same channel with me! (5 routers!)

CH 11 by default! i have set my router to 7 :) it's was clean!

and no problem since! none :)

my level is the high and strong!
[HD2 Android NAND Development] petbede:
Hi there,

Just pondering and wondering if u can tell me how to change the channel

PEACE!!!
[HD2 Android NAND Development] MystaMagoo:
These 2 are updated version of what's inside rom.

At least for me they get updated when I go check in market.
[HD2 Android NAND Development] officialbambam:
Is there a way I can put this rom in my phone without the customization's. I just want everything to look like a stock androids icons and menu.

[HD2 Android NAND Development] dorimanx:
great!

i will use it also! :)
[HD2 Android NAND Development] officialbambam:
I'm moving to this rom, so do I download the regular rom, and download the new update to this rom, then convert to the stock theme?
[HD2 Android NAND Development] MystaMagoo:
Just wait some minutes as DM is about to upload new rom?

Or if you want to go to this 2.8.8 then...

[HD2 Android NAND Development] officialbambam:
Thanx for the information. I'll just wait for the update.
[HD2 Android NAND Development] dorimanx:
OOO Yeee!

some more tweaking and reducing overhead of read ahead! lead to faster write!

and this is the source of all stuck and lag!

60MB file write to EXT in 4.3SEC!!! :) 14.2Mb/s :)

Read reduced, but it's nothing compare to Write speed increase from 6MB to 14!!!

Someone mentioned the WiFi Signal Strength issue again...

Last we "touched" on this situation, no-one including dorimanx could figure out what the real issue is as he himself doesnt have an issue and since no logs can be made from a simple drop/disconnect... well.. FUBAR is the name of the situation!

I will state for the record that I have also previously mentioned having this issue as well, and while its supposed to be "power saving" for me, its anything but since it has to reconnect and retry so many times (and I have to wake it back up to make sure its finished and/or start it again)... I am in eyeshot (17Feet~) of my router and I have yellow/red signal strength, NOW thats not the only thing, because Dorimanx is right, signal strength NORMALLY doesnt mean anything, that being said however I can start a download or 2, and sometimes (read not always) the signal will totaly drop, or the download will be interrupted/have communication error, basically WiFi just sucks!

I have tried 3 different WiFi routers, made sure that my Router was on a unique channel so as not to overlap with other's, and used the stock, 5dbi, and 7dbi antenna's for my router, and the issue still persists, additionally, in my own personal testing when I put WinMo back on the device, the signal is green (well 4 bars) all the way to the gate on my property, doesn't cause download issues, and rull rate/ping is fine.

All that information aside, I dont know if its the driver, or some config for the WiFi, but for the looking I did for myself, I just dont know why the issue exists, or even how Dorimanx could fix it if it happens to be a driver issue! I also had this issue when I tried Hyperdroid as well, haven't tried others, really should have tried Energy's rom as I used his WinMo TP2 mods and they where great to compare against.

As it stands I have given up the hope of a "non" power saving* or just better wifi stability in exchange for the rest of the ROM being stupid fast, IE games that would normally jitter dont, listening to my AudioBooks dont skip/jump/take forever to load, and of course, the massive use of SWAP/EXT and RAM without running into complications just make this ROM the one to use if you want true device performance!

*I almost want to think that somehow the WiFi Radio is being effected somehow by undervolting or something causing the issue, but I doubt/am unqualified to speculate on the real issue.

Thats all I have to say on the subject, as last time it just became a giant pissing match with those with WiFi issues on one side, and those without on the other (kinda like the Keifer kernel problems, even though I like it better :P )
[HD2 Android NAND Development] dorimanx:
OMG!!! :)

it's not a fake!!!

# sh sd-ext-read-write-60MB.sh

it's real + buffer! but it's great!!!!
[HD2 Android NAND Development] odoss:
Man you should put a video demo of your build in youtube for example so we can see the updates, especially when talking here about DATA to EXT, in my experience i've installed many builds using that before and it's very VERY laggy ! so you're talking about speedy writing and reading, a video demo should do the work would be great!

Issues with this ROM and Android Market

Ever since I installed this ROM, I've been getting errors in android market. I don't know if this has been mentioned before on this thread, but here it goes...

Every time I try to search or download some apps from the market, I get an error: your device is not compatible with this item

The most recommended solution was to change LCD density to default 240, but my LCD density is already at 240 (I checked build.prop) and I have cleared Market cache several times and rebooted phone, still no go. I have even reverted to the old Market and I still encounter the same problem.

It's really frustrating because I have some apps which I previously paid for, but can no longer access or download them because of this error.

If anyone has a good idea on how to fix this, please let me know...thank you.
[HD2 Android NAND Development] Hammerfest:
Hello, I myself do not have this issue, however we need a bit more information to TRY and see if we can recreate the issue! Mainly, what software/app is it that you used to use w/o issue?

~Ta
[HD2 Android NAND Development] WOOZ!E:
OK, when I search for Wolfram Alpha in the market (on my phone) is doesn't show up in search results, but when and do the same on Android Market (web version) it shows up, but it won't allow me to download it from the web. rather it says: your device is not compatible with this item

There are also a few other apps which I can't remember off the top of my head, but they either don't show up on android market nor install.

where have download link ? :( i can't see

---------- Post added at 11:35 AM ---------- Previous post was at 11:20 AM ----------

hi everyone :)who can give me link
[HD2 Android NAND Development] Visentinel:
Hi dorimanx I'm really missing your rom ... Could u please help me by making a new sdrom with your awesome tweaks.

Mtty and recovery both show my nand is a write off. This sd based sense rom is nice but god its slow.

I'm suffering, please put me out of my misery. Lol.

In the sd development forum there's a system.ext2 builder and you use the linux shell to create an ext4 data.img 1gb
[HD2 Android NAND Development] Visentinel:
Sorry, in the sun and can't see what I'm pressing.
[HD2 Android NAND Development] dmunseyautotech:
It looks to me you need more ext partition space. May have to move your files from sd card to a folder on computer. Format card make a bigger ext partition and then reload files to sd. Just my thoughts let Dm check it to be sure.
[HD2 Android NAND Development] hd945157206:
where have download link ? i can't see

who can give me link
[HD2 Android NAND Development] Visentinel:
Blind much? There's 3 huge buttons in the OP that says download.

Good news folks, quallcomm has released the specs on the snapdragon S4. The Krait cpu will be faster than the pentium 2.

Clock speed is 1.5ghz to 2.5ghz. =O
[HD2 Android NAND Development] tmotard:
Ok but that doesn't work from xda app without opening the page in the browser :)
[HD2 Android NAND Development] pee-wee:
Yew, you must open those link from browser
[HD2 Android NAND Development] Visentinel:
Oh Good, might of got back in-time to tell you something else thats important about SD roms Dorimanx.

Booting them from MAGLDR requires something special done to pass the commands to the kernel otherwise even when you boot the kernels from the sdcard folder the kernel loads /system and /data from the NAND partitions.

Heres an INITRD from the rom im using at the moment that successfully boots the latest Tytung and Heiros kernels to sdcard located system and data images.

Sorry for initrd in a .gz in a .zip - forum dont allow .gz extension.

Another thing.. maybe it might be much easier to have the following setup...

Magldr boots ad sd

Initrd configured for SD boot

Kernel opens system image

Rom is configured to use SD-EXT for entire data like the NAND to sd-ext approach.

Just when I can't imagine anything better about this rom, an update comes making it even faster, even cooler, when it's already mind blowing!

Guess we'll just wait for DM to cook in the new

My 5 cents for all the joy and support you've been spreading with your work!

[HD2 Android NAND Development] Lextermina:
Yeah Wait the Bomb :)
[HD2 Android NAND Development] Visentinel:
Dammit, i dont know what im doing :confused::(

I tried using the system ext2 builder myself and i used a test 2gb card.

Built 2.8.8 rom with v11 kernel and new data to ext v4 and put a 256mb data img.

It wont boot, the kernel doesnt even boot far enough to give me logcat, thats how bad it is :(
[HD2 Android NAND Development] wifi75:
I've installed again all:

2.8.8,fix but with the same problem of market:

In section (my application) I do not see all installed applications.

Why? :confused::confused::confused:

:(
[HD2 Android NAND Development] dorimanx:
I have idea!

do you still have ROM zip of any kind! that market worked with it????

if YES!!!

then get the build.prop from it! and zip it and post it.

i will look inside and make changes to our build.prop that will allow the marked downloads again!

Thanks allot
[HD2 Android NAND Development] haysnamrip:
yeah you are right but actually i had 1.89gb ext4.. i think, i should format the sdcard as u suggest.. :D
[HD2 Android NAND Development] dorimanx:
Very strange!!!

you data is on EXT and looks all ok!

but you get error in debug log that you dont have room on EXT to copy DATA!

but you did that already!

Hmmmm.....

i will look in my script , and check why it's trying to mode data again!

Thanks.
[HD2 Android NAND Development] dorimanx:
Looks good!

but you can do some cleaning on sd-ext!

there are files that now on NAND data, and you dont need them on EXT

What posted below you can delete from EXT only!!!! all the rest DONT!

Never delete them from nand DATA.

[HD2 Android NAND Development] dorimanx:
i will look at that, when finish new ROM build from update-cm-7.1.0-Desire-signed.zip! STABLE!!!!

i was about to upload new patch and then this appeared!!! :)

Best to make full ROM with all tweaks...
[HD2 Android NAND Development] dorimanx:
Thanks for support!!! :)

i am building new ROM from STABLE version!!! :)
[HD2 Android NAND Development] dorimanx:
just download some free app.

then leave the market running in background.

it's will make a list and apps will appear,
[HD2 Android NAND Development] ORiZorrie:
Yes, that is about the potential corruption of data because of power loss. That wasn't my question actually.

If I understood correctly, you tweaked the IO to speed up the read/write and because NAND was a bottleneck due to hardware limitation, you store the data to EXT.

However, to my understanding the access time for EXT is a lot higher than for NAND. That means for smaller files (most system files) the access-time + transfer-time will be smaller from NAND than access-time + transfer-time from EXT. Certainly for READ operations. I haven't checked for Write yet.

I have been doing some reading on this topic and found this so far:

- SD read access times vary between 2 ms and 20 ms (Milli-Seconds) depending on card specs.

- NAND read access times are something in the scope of 50 ns (Nano-Seconds) - 20 µs (Micro-Seconds).

So worst case scenario for NAND and best case scenario for SD, read access times are still thousands times faster on NAND than SD.

Therefore I really doubt whether data to EXT is the better choice here.
[HD2 Android NAND Development] dorimanx:

Can you tell me what app you cant download?

and was able to with Hyperdroid?

Then i will do tests and find what can be done!

Thanks.
[HD2 Android NAND Development] dorimanx:
yes this can be correct!

i didnt rad about that for now.

but one thing i know! nand can write only 2.7MB/s no more! no way to push it faster!

so it's actialy sucks when you store new data or do restore.

and sdcard write 8MB real write + 6 to 9MB RAM bufferd write!

This why the quadrant not stuck on database check and show 7000 score for I/O and not 1430 when on NAND!!!

we have plenty of read speed! 12mb real + 30MB buffer!!!

small delay in read is not felt as huge delay in write!

when phone write and suffer you cant run any thing, it's stuck! long time, then released.

i can admit that when using lots of apps that site in RAM on high end + SWAP my phone sometimes lag for second or two...

but i am working on it! and made good progress, now it's faster.

but user with light rom and not much apps in ram will feel HUGE speed up!!!

Trust me i have tried.

and rom with stock apps will be atomic edition :)

+ your NAND get a release of stress all the time by slow write.

i prefer to buy new SD after couple of years!!! then replace phone, and suffer from bad blocks!
[HD2 Android NAND Development] kantjer:
Sorry my bad, There are a few apps like Google Maps I cant download when using the PC version of Android Marked, but I can download them via the Phone using the old_hacked _marked

On Hyperdroid I could DL (from PC and/or phone) after setting screen density to 240 and clearing marked cache, now with the hacked marked there is no need to do this any more.
[HD2 Android NAND Development] Visentinel:
YAY!!! I will look forward to this :D:D:D:D:D:D:D:D:D

Thankyou Thankyou !!

---------- Post added at 09:15 PM ---------- Previous post was at 09:00 PM ----------

Guys, the other thing is when we are using buffered writes and buffered reads the speed of the flash is irrelevant, especially with buffered writes, then the access time is even faster than internal nand, we would be talking access times in the areas of RAM here, that's where buffers are stored.

With a sufficiently sized buffer, say 4 megabytes, then as long as a single write operation is smaller than 4096KB the entire write operation will seem Instant.

For Example If the write speed of the flash card is 2mb/sec with a 4mb buffer. if you send 4mb to the flash card and then wait 1 second and send another 2mb... the phone would "feel" like it has a rocket strapped on.

[HD2 Android NAND Development] dorimanx:
NEW ROM! STABLE 7.1.0 CM7, version 2.8.9!

Hi,

I am uploading new ROM 2.8.9!

It's based on Stable CM7 7.1.0!

Change Log:

***Updated Superuser to 3.04 + SU

***Updated the Google Music App

***Updated Voice Search

***Updated GPS Status

***Added tweak that will convert your EXT3 partition to EXT4 on boot!!!

This is in case that you still don't have EXT4! if you do then it's skip!

***Added lots of tweaks for faster internal transfer + usb transfer.

Please do not expect huge improvements! we already pushing the TOP! :)

But stability is also very important! i did my best to provide it.

On heavy ROM delays can be still expected if data moved to EXT!

The sdcard struggling to keep up! so in case of unbearable delays move data back to NAND! using the REVERT data!

This mod is designed for LIGHT ROM or not heavy HIGH END

(HEAVY ROM = more than 45 services in RAM + 50MB used swap!)

***Updated all packs of DATA to EXT to version V5

No need to install them if you already moved the DATA to EXT!!!

Just install the new ROM and keep working as was!

If you didn't install the DATA to EXT and don't want to, then also just install the ROM and all will be as was :)

***Added the Wrapper 4B PPP files to improve DATA connection on CLK!

***Installed the HierOS 1.7.4 as DEFAULT kernel in ROM!!!!

For now please do not change it! i need to rearrange all Kernels in mirror and upload V12 of each kernel!!!

Tried to make the Speaker Louder but got the ECHO on call, so i reverted it back to normal.

i will keep looking for better solution!

HAVE FUN!
