It's not about NativeSD, it's about the bootloader. I am using NativeSD on cLK and I'm using PPP, because my bootloader is cLK. And Data is working just fine.

Besides, no one has any problem with rmnet. People are facing issues with PPP.

[HD2 Android NAND Development] Robbie P:
Have you tried re-installing and changing rmnet/ppp option?

Also are you running short of ext4 partition? Funny things happen then.

Also in earlier sd builds, tytung's rmnet to ppp update worked to fix certain people's data problems, for some reason the installed files didn't work and applying the update fixed it. Worth a try.
[HD2 Android NAND Development] sanos99:
I have installed DOZENS of ROMs, backed up data, started configuring, until there was a bug (either Wifi, tethering, bluetooth, sync, stability) which made the ROM unusable on a daily basis.

The first ROM I have tried was this one but I flashed it wrong (NAND instead of sd-ext on a EU HD2, wrong partition size etc). I came back to it a few days ago and I can state that it is by far the most stable and the fastest one, from froyo/gingerbread up to JellyBean.

For those still having bugs after installing this ROM, I am writing a short flashing method that will transform your phone into a modern one look alike:

1. Install HSPL 2.08;

2. Install Magldr

3. Partition correctly with Magldr: 5MB cache, 285MB ROM (choose custom and type 285 in the textbox, then repartiton with HD2 tools)

4. After partitioning, you will have access to AD Recovery.

4.1 Use AD recovery to partition your SD card: 2G sd-ext, 256M swap.

4.2 Use AD recovery to mount USB storage, copy ROM and upadates on the card.

4.3 Flash ROM then reboot. Do NOT boot.

4.4 Flash all other updates. Reboot phone, go through the setup.

To recover, use either clockworkmod or Titanium backup. Both worked for me, even if with several particularities.

All tools used (HSPL, Magldr, HD2 tools) are easily found by doing a search in the site.

WIth this ROM, I have used SD-booster with a 2048k cache and SD-tools to check the speed. On a 16GB, type 10 SD-card (I use two, a Sandisk and a Kingston), I have acieved 7.5/24 Mbps average speeds (write/read). The system is as responsive as my wife's Samsung S3 mini. Cool huh?
[HD2 Android NAND Development] doctorasgr:
What all other updates? :confused: I have tried (I am so tired saying it again.....) many different options (including this one you described above) but all I get is SODs. I have an HD2 EU. Could you please tell me why this is happening to me?
[HD2 Android NAND Development] NYLimited:
Yes, unfortunately you need to eliminate possibilities one by one.

If you install the ROM after a factory reset and you install nothing else for a few days you have two possibilities.

The ROM hangs - in this case it is something to do with the ROM or the hardware or a combination of the two. I would start looking at things like sd cards (if using DataonEXT or NativeSD) and other similar possibilities.

The ROM runs clean, without any hangs - in this case it must have something to do with one of the apps you installed. At this point I would consider installing one or two apps only for a couple of days, adding another one or two after a few days if no hangs. Eventually you will get the device to hang again. Now go back and remove the last app you installed. If the device runs fine again you have your answer.

I agree, this is a pain to do but too many people, including myself, are running this ROM daily without any issues. There must be something unique in your installation causing the problem.
[HD2 Android NAND Development] b-16707:
system runs uber slow compared to ICS (i had the ICS version before dataonext was added) . JB has constant program crashes and system lags. could it be i need a class 10 sd card? i only have the original sandisk (unmarked class number) card. ICS ran fine on it, super fast super reliable. no mention of needing a fast card in the original post.

[HD2 Android NAND Development] MarkAtHome:
Have you played with voltages, at all?

The reason that I ask is that the

default

voltage settings for speeds up to 460MHz is set at 1000mv.

If those voltages are not modified, I do not see any gain by setting minimum speed to anything less than 460MHz (besides, some processes struggle when limited).

Am I misinterpreting its meaning?

Total internal space only 124mb on T-mobile HD2

Excuse me, I changed from leo512 to leo1024 yesterday, and keep using this great rom.

But after I flash this with NAND type of full installation, I found that my total internal space only has 124mb and can't install anything.

Was that anything I should do before installation? Or how to solve this problem?

Thanks!
[HD2 Android NAND Development] NYLimited:
You most likely can use a better (faster) card although I doubt Class 10 or Ultra will help that much. If you are using DataOnEXT there are many other variables besides the SD Card's speed when it comes to fine-tuning the OS and making it run fast(er). It is not probable that any one answer by itself will do magic for you.
[HD2 Android NAND Development] b-16707:
Does 30mb sec cards work well? Any advantage with a 95mb sec card? Cab the system even utilize something that fast?
[HD2 Android NAND Development] NYLimited:
How much space is in your system partition??

Sounds like you are running very low there.

Try increasing system a little or use DataonEXT which let system be very large, if needed.

Battery drain

I have aproblem with my battery , it is draining very fast specially in standby mode and secondly in screen !!!!!!!!

Any ideas ?
[HD2 Android NAND Development] b95505017:
I follow tytung's first post with 285mb partition.

I just curious about how much the total internal space should be without install any script, just pure NAND installation.
[HD2 Android NAND Development] NYLimited:
I don't recall exact numbers off-hand but in any event, Tytung's numbers are the ideal or recommended numbers. They do not (cannot) consider any possible bad blocks your device may have. Your issue may, however, originate from insufficient space in the /system partition, not from too little internal memory.

Roughly, total ROM size, less all the partitions you created (misc, cache, system, recovery) - whatever is left is traditionally given to "userdata". BUT, some things require space in system and even when you allocate 285 MB for system you could have quite a bit less IF you have bad blocks on your device.

I use the DataOnEXT install method which places all my apps and data on the sd card (ext4 partition) without any scripts. That means the traditional userdata partition remains unused so I can make my system partition much larger (and safer).
[HD2 Android NAND Development] sanos99:
For the moment the only update I found of help was the one (found in the first post) disabling the softkeys (I personally wish for more space on the screen).

I have got SOD too and I couldn't figure out the problem, since I totally formatted my two HD2 EU and I bought two brand new 16GB, Class 10 Sandisk cards to equip the phones.

A few days later, after many many trials, I discovered that the phone freezing or hanging or giving me all sort of headaches had the same card in it (I used to swap the cards between phones). I bought a third one and dismissed the alleged bad card and a miracle happened. No more troubles, no more issues. So I know for a fact that even a brand new card may be bad. Windows is also giving errors on that card on a daily basis, so now I am sure I have pinpointed the bad component.

In order to give you an advice in discovering what is wrong, I suggest the following steps:

1. install a Windows 6.5, stock or whatever version is the least buggy and let it o the phone for a few days (using the phone of course). Don't use any sd card this time. try using programs that use the sensors of the phone: gps, magnetic field sensor, accelerometer, compass, proximity, light, etc

2. If everything goes well, it means your CPU, nand, ram and sensors are OK and you can proceed to the next step. If not, something is definitively wrong with your phone and you should get an other one or avoid using one of the (faulty) sensors later.

3. Assuming step 2 is OK, put an sd in the phone, thoroughly tested without errors. (try formatting it in windows, but not in quick mode, using as formats both fat32 and ntfs, two or three times). reinstall windows with some apps but on the card this time. Play with those apps for a couple of days and look for freezes, hangs or slowdowns of the system. If you experience such manifestations, either your phone card reader if faulty or the chip reading the card: you can't do anything in this case except stick to windows if you don't want to throw away your phone.

4. Try using an sd distribution of android, launched though haret from the sd-card, use it for a couple of days. This stresses your card on the file containing the image of the ext4 data partition. However, I think that if you have arrived here, android should perform well. You cand try even this ROM, since it can be installed solely on the sd-card.

5. See my previous post and be careful about all possible errors while flashing android on nand. When I say errors, you may include faulty or defective: usb hub, usb cable, usb computer port, wrong drivers.

6. Use android as it comes, without any other apps, for a couple of days. Then try installing one-two apps a day and follow the system's performance.

This step-by-step procedure should pinpoint exactly your issue, I hope for your sake it is not one of the phone's components (nand, ram, card reader).
[HD2 Android NAND Development] b-16707:
bah. i guess i dont fully understand the background work of roms in general. shouldn't it be optimized for the HD2 basically "plug n play?"

oh well went and purchased a card before i read your message. relatively cheap nowadays anyways, wont hurt.

[HD2 Android NAND Development] DarrenNewsgroup:
This is an interesting point. Are you suggesting that clock speed of 245MHz uses 1000mV of power and that this is the same amount of power as used at 460MHz? Therefore you presume both use the same power (= same battery life) so why not use the fastest speed?

There is some logic to that argument and I can't fault it, however, common sense says that it must be wrong as the ROMs have provided 245 for years. Why provide the option of 245 (and set it as the default minimum) if there is something better for free (more speed for the same battery life), I.e. 460.

I guess a simple test to check your hypothesis would be to fully charge they phone, put the phone in airplane mode and set max speed to 245 and former to performance (always run at max) and time how long to drain the battery. Recharge the phone and repeat but with max at 460. If your hypothesis is correct both should take the same time.

Would you care to do the test MarkAtHome?

Edit: Corrected 100mV to 1000mV

That is exactly what I am saying (1000mv, not 100mv).

You can see

modifty this via Android Tuner, ROM Toolbox and other such utilities. You can change the voltage associated with each individual speed from its default.

FWIW, Tyween provides his settings on the OP of his thread re TyphooN CyanogenMod 7.2.0.1.

This is not new stuff, nor is it my hypothesis, but it is often overlooked, and posted misinformation appears to be quoted endlessly (on this and just about ever other subject), similar to what you might discover when playing the children's game of "telephone".

[HD2 Android NAND Development] RavenMad:
Try increasing your system partition. I had multiple FCs at 285MB (probably bad block in NAND). I've now set it at 320MB and Data@EXT4 and it flies (SanDisk 32GB Class 10 Ultra).
[HD2 Android NAND Development] sanos99:
Other considerations:

1. SD Card

ny-limited has a very comprehensive guide about sd cards here: http://xdaforums.com/showthread.php?p=33091722

Take his advice on choosing the right sd card for you.

2. EXT partition size and SD card size.

Normally, even a 4GB card could accomodate the needs of a user. Some users might be unhappy with even 23G cards. You might consider the following:

2.1 The EXT partition size will hold all your data as well as your programs. For a regular user, a 1G partition would suffice. If you plan however to install tens of applications, you might consider enlarging this partition to the maximum of 4G.

2.2 The remaining FAT32 partition will have to accomodate the following:

- camera and video shots;

- your personal documents;

- your music and videos;

- your recoveries, made with either Titanium backup or cwm.

All of these take space and imho an 8G card would do for a regular user, up to a 32G card for a video passionate.

3. Battery drain

Android does not drain your battery much more than windows, if installed stock without applications.

In the need for speed, many users get prone to advertisements for task killers, Sd boosters, battery monitors etc. All these applications have background processes that drain your battery even when the phone is in sleep mode.

This ROM uses in average 3mA without any "enhancing" app installed. With task killers and SD boosters and battery monitors it can easily jump to 100mA in sleep mode, transforming you into a slave of the wall socket, always having to recharge your phone when you most need it to TALK.

Because, let's face it: HD2 is a Phone, a versatile one but not a tablet, it has a single core processor as opposed to the high-end devices with 4 cores. One should use the phone to talk and do basic intelligent stuff (more than with Windows, that's why we choose Android), not to overclock it to play HD games that won't be seen anyway at their true value.

Tests:

1. SD Booster

WIth this ROM, I have used SD-booster with a 2048k cache and SD-tools to check the card speed.

On a 16GB, type 10 SD-card (I use two, a Sandisk and a Kingston), I have achieved 7.5/24 Mbps average speeds (write/read).

Without SD-booster, I have achieved 7.1/29.5 Mbps average speed.

2. With SD-booster and a task killer, my enhanced battery got to 50% capacity in 18 hours. After uninstalling both SD-booster and the task killer, the same battery lasted to 50% capacity 38 hours.

Picture 9 is showing the drain with SD Booster and a task killer installed, in the left side of the graph, and the same thing after uninstalling both apps. The picture is worth a thousand words.

[HD2 Android NAND Development] marco.palumbi:
there are some things that you must consider about power comsuption in a cmos device:

current sink (and thus power), at parity of voltage supply, is almost proportional to the frequency at wich the device operates.

power consumption, at parity of frequency, goes with the square of the voltage

switching speed is tight to the voltage supply, so increasing the clock you must increase the voltage.

so, lowering the frequency at parity of voltage, it reduce the power consumption for a given amount of time.

obviously the same task is done in more time......
