[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] truc007:
It's seems to be a USB driver problem on your computer side (or a defect USB cable). Make sure Win update the driver (Internet connection needed).

You can also flash from SD. Put the "ROM" on your SD with a specific name (sorry don't remumber which on, I think on HD it was Blackimg.something). Look on xda or google for the correct name.

Ok I've google it for you: "Take the ruu_signed.nbh from an original ROM, put it on the root of your SD and rename it as LEOIMG.nbh", then follow the advice in the previous post (boot, press sound key down...)

Sure it has been explained many time on XDA :rolleyes:

And just for fun... make sure the USB cable was connected :D
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] imanh:
You can use another method ,

1-Turn off the phone

2-attach usb cable to phone

3-turn it on still keep pressing the power botton

4-go to aMagldr boot screen ( not multi-color screen)

5-choose #5 option ( USB flasher) (upp and down with volume key)

6-then press answer botton

and you would see the usb connection to pc if not for surely ur cable is damaged so try another cable

This is my very first Android device. I'm very pleased with it, but I'm looking to do more with the device. However, I'm scared to take the first step in fear of bricking the phone.

My question to the posters of this forum is:

1) What is the easiest and most simple way to root and overclock my phone?

2) What do I have to look out for while trying to root my phone? Any precautions to not brick my phone.

3) Is there only one method of flashing a ROM?

4) What is the best ROM out there right now? Been reading a lot of good things about Cynanogen(?)

Any advices would be great!!

[HD2 Android NAND Development] dandiest:
This is my development based on Takaaki's initrd, during I develop my build at http://xdaforums.com/showthread.php?t=913597, I spent a lot of time to enhance the data2sd and ext4, after studying almost all the popular methods: App2SD, Data2SD, Data2ext, Data2whatever, I develop this:

Features:

1. Support both data 2 data.img or ext4.

2. Support SquareFS.

3. Auto-format the 2nd partition with block size of 4096.

4. Utilize the Nand data partition to improve the performance.

5. Switch the PPP/RMNET.

6. Config the gps_zone

7. Support the update without re-flash. (you can fully customize your build based on this feature)

8. Backup the ext4 to data.img (implement in future)

9. Restore the data.img to ext4 (implement in future).

To enable external data.img

1. create '.data' folde under sdcard (/sdcard/.data).

2. create 'config.txt' under '.data' directory.

3. copy old data.img to '.data' directory, otherwise a new data.img will be created.

4. boot into Android.

Config.txt for data2SD.

To enable ext4

1. create '.data' folde under sdcard (/sdcard/.data).

2. create 'config.txt' under '.data' directory.

3. Config.txt for data2SD.

For first installation, it is always good to set the format_ext4=1 to format your ext4 partition with proper block size, after 1st boot, change it back to 0.

To config PPP/RMNET and GPS_ZONE

ppp_mode=1 will enable the ppp, set to 0 will use rmnet.

gps_zone='your country code', - country code, us, fr, jp, etc

To update/customize your build

1. Create a folder /DLZUPDATE under your sdcard.

2. put your app's apk under AndroidApps in /DLZUPDATE, that apps will be automatically installed into your data partition.

3. put your kernel file or other under root in /DLZUPDATE, all the files under root will be copied to your build, if your want to upgrade your kernel, just put zImage in /DLZUPDATE/root/system, and module files under /DLZUPDATE/root/system/lib/modules. etc.

Download

View attachment 492146

Install

1. extract the zip to a folder on your pc

2. backup your existing initrd.gz using adb

3. In "command prompt" env, run install.

4. your existing initrd.gz will be backup at the same folder named backup.initrd.gz.

5. if your have problem to boot into the system, just try: adb push backup.initrd.gz /system/initrd.gz. (even system can not be booted into the launcher or sense, in some point of time, the adb still can function, so just keep trying.)

Caution: if your build current use app2sd, you have to disable it before using this, rename the init.local.rc under etc to init.local.rc.bak, remove the 00start, 04apps2sd from /system/etc/init.d.

If your build uses boot partition, you should change the installation script to push the initrd.gz to replace the existing one wherever it is.

Thanks to

[HD2 Android NAND Development] jpl69:
Ok, i've managed to understand the concept of data2ext, and when on initial setup everything gets what i expect, i've 1 GB (depends on ext partition size) of free memory space, but i get an horrible performance even if formated with your tool, i guess it's SD performance/quality because i can't run any ext build published here where most of users claim to get good performance. So i try data2sd but instead of the 512MB (img size created with this) of memory i get only the 80MB of the free nand internal ram. What is stored on this img file ? only settings ? On 20 applications i use only 4 are movable to sd, so after my initial setup (and of course with good performance) i get a lot of memory low warnings.

Thanks

Looks like the data2sd was not enforced, what's your configuration in config.txt?

[HD2 Android NAND Development] jpl69:
I'm sorry but with all this flash/unflash install/uninstall download configure i've lost my config, but i'm sure data_img=1 and data_ext=0

(just a note gps_zone=pt should configure gps to be used here in Portugal right ?)

If you say that it should work i'm going further with my tests and post here results because i don't want to flame this thread.

Update:

I've a stock 8GB class 4 card swaped with 4GB class 2, results on nand/ext4:

Initial setup (with format ext4) 1/2 time, second boot 1 minute and everything runing muuuch smother and faster so or i've got a malfunction card (?) (and i've read someone complaining about a 16GB class 10) or lowest class gets more speed (?)

Update2:

The diference is really amazing, i've got a completly functional android now with this card.

You should mention on your threads that if you get bad results on initial setup forget about that nand, return to SD builds or get other card.

Can you please post your card type please ?

data.img Question

3. copy old data.img to '.data' directory, otherwise a new data.img will be created. ... Can I somehow set how big will the data.img be ?
[HD2 Android NAND Development] dandiest:
Default will be 512M, you can config it by data_size.
[HD2 Android NAND Development] pinobigbird:
Looks promising

This new initrd and file management seems well thought through and very promising. :)

In other builds I experienced that there can be a huge performance difference between the different file management choices (full NAND > adsd > ads2+ > data2ext > data2sd). It's good to see that you got into this subject and tried to find an optimal solution which can be configured by other chefs.

I assume that you implemented all this in your own DL DesireZ v2.5 build? If I find time I'm certainly gonna give it a try!

Looks like the system in Gauner1986 build is read only or have the boot partition, or really occupied all the space? anyway, your existing build should be unchanged.

you can try adb shell ls /system, or adb shell ls /boot, whether there is an initrd.gz under it, then, manually push all the necessary files.

Hi @dandiest

Thanx for this. Though, just wanted to know, is it possible to push "initrd.gz" file using Root Explorer? If so, where should I put the file in android system. Couldn't find an answer, after searching, hence thought of asking here...
[HD2 Android NAND Development] 10507:

[HD2 Android NAND Development] dandiest:
You can open the install.bat to know where other files need to push.
[HD2 Android NAND Development] dandiest:
What the config do you use?
[HD2 Android NAND Development] dheerajk27:
Hi

Thank you for the reply. Though there is something wrong with the entries related to the binary file "e2fsck" in install.bat :-

adb push e2fsck /system/bin

....

adb shell chmod 755 /system/xbin/e2fsck

So where to push the same? To bin or xbin? Sorry, if the same is already mentioned somewhere...
[HD2 Android NAND Development] pinobigbird:
Looking at the location of the file in another build it is "/system/bin", so I think the last line has to be

adb shell chmod 755 /system/bin/e2fsck

Thank you Daniest!

Would be perfect if this works :-)

I'm using thist ROM: http://xdaforums.com/showthread.php?t=908528

and as suggested I used ext3 instead of ext4 because then this build is faster, but it has still some lags...

So, if got some questions about your initrd:

1. is it possible to use this with ext3?

2. if it is possible: does it also improve the spped like it does with ext4?

3. if it is NOT possible: once you have implemented backup and restore of the ext4 partition, is it going to be possible to backup my ext3 partition, format to ext4 and erestore the data with your initrd?

4. have you compared ext3 and 4 regarding speed? as ext3 is much faster with the ROM I'm currently using, would there be an advantage if I switch to ext4 and your initrd?

I'm hoping you can answear my questions...

But either way: Thanks for your work and thanks for sharing it with us :-)
[HD2 Android NAND Development] dandiest:
sorry, should be /system/bin.

is this initrd working when booting from SD or from MAGLDR SD ??

i have tried to write my own init file lastnight based on Takaaki (http://xdaforums.com/showpost.php?p=10285868&postcount=1)

but the problem is even with takaaki's original initrd file... the phone hangs after "exec init.android" when booting with system.ext2 file on SD!

i tracked down, and write a log file of the complete init, had someproblems with takaakis using of loop9 device... don't know why... everytime i get errors about mtab... solved it with using loop0 ...

after that i'm mounting the system.ext2 to loop1 like in hastarins initrd from good old SD Builds... but also didn't work:

mounting data.img
finished mounting data.img
onsd_card
/bootsdcard/ANDROID
Using uncompressed system

The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>

exec_init

btw, hastarins initrd file is stillusing the rootfs.img ... and i'm want to get rid of this !!

i want to have 1 initrd file for NAND and for SD(haret/magldr) Boot...

i've created some options to set the service line in init.rc corretly (add/remove nand_init, also change ppp or rmnet)
[HD2 Android NAND Development] dandiest:
This is for nand only, I have made a initrd for SD which can load from both magldr and SD and has the same feature with this initrd, but I want to go further to load some most frequent access files into RAM, still testing... once it is successful, I will merge it back to this nand initrd.

great jobs bro.. currently I'm using your init file (not the whole initrd.gz) because I believe ur initrd is optimized for sense build..

Hello dandiest,

sorry for bothering again...

what are the differences between nand and sd initrd files??

also i have the problem that with cedesmiths new initrd file that was built for SD only (without rootfs) the miui builds won't boot up... just hangs...

thx for helping
[HD2 Android NAND Development] dandiest:
They initiate different devices, SD mmc, nand mtd.

BTW, why does miui need rootfs?
[HD2 Android NAND Development] lesjaw:
hello future..

I was able make miui boot using new cedesmith initrd file.. what you need is you have to change init.rc and init.htcleo.rc .. I'm really sure..cedesmith initrd.gz was designed for sense build.. if we just use his initrd.gz file it will make boot fail or make some components didn't work, like Bluetooth and FM radio..

I was use init files from cm build..

one thing bothering me is..when I boot android from ad sd magldr it freeze on lock screen..

did you see any sdcard build success with magldr ad sd boot?

@dandiest

so I now, run your init file for my build for a couple of days, what I experience is :

data on ext4 partition

- homescreen does have fast performance

- gtalk has delay sending text after taping send button

- Gmail previous and next button also has some delay..

- MIUI screen capture fail, can't save PNG files on sdcard.. but third party screenshoot app work just fine

data on data.img

- everything are very awesome ..
[HD2 Android NAND Development] jan-willem3:
lesjaw I am using the same one as you it indeed gives great performence. But it ** bluetooth and fm radio what you said. MIUI Is not designed for ext4 btw.

Edit g.lewarne just tested the same for me on cm6 rom and also there is a bluetooth crash. It should be because there is a difference in bt for cm6 and sense. So if possible fix this issue.
[HD2 Android NAND Development] lesjaw:
hello JW..

actually bt issue is because of we must start btld service first then hciattach service (darkstone passing this knowledge to me).. by using a right init.rc (or modified dendiest init.rc) we can fix this issue..

BTW, I read u thread you have fix this issue right? or do u use manus initrd.gz?
[HD2 Android NAND Development] jan-willem3:
I use the same initrd.gz. So we need other init.rc can you tell me where I can find or what I need to change. If you need help with other things just ask me btw.

I tought I fixed bt issue but it still exist so it isnt fixed.

Edit I see you made ext 4 working nice.
[HD2 Android NAND Development] lesjaw:
you can take a look my current initrd.gz files, unpack it .. then take my init.rc and init.htcleo.rc then put dendiest init file.. pack it again as initrd.gz ..

tomorrow I will release my new build with dendiest init file .. u can use it bro.. I believe it will run on cm build too..
