or are there any other methodes to run his system, we don't know why the sdext not worked....
we need help very fast, please help!!!!
thanks a lot

I have these backed up on my SD card & PC too. But I'm afraid it has some private stuff also backed up.
I reccomend you installing a stock rom again and root it (installing a stock rom unroots your phone).
Like in this thread:
http://forum.xda-developers.com/showthread.php?t=918939 Be sure you use the latest ROM and read the full thread!
Also why don't you try another rom, see if it works? ANd make sure you wipe all data (factory/cache dalvik)

how we should install that when we can go only into recovery mod, we can go to sd card but the link you give to us, there is only a rom with is a exe.
can you give us a deteiled introduction? we aren't so good in these things :S pleaase help.
edit2: we can't start the phone so we can't chose htc sync...

The tutorial and ROM you should use:

If you can't start the phone, then search the forum here for solution...

the problem is, we dont have android on the phone now, no datas nothing, we can pnly good to recovery mod...
we need to install a backup or something from recovery that we have a system on our phone....
so we should need help! ((((((((
edit:
an idea nagypapi :
maybe you can backup you data now, then wipe all your data and flash a completly new rom, then you can make a backup from the completly new rom and than you can give us the backup files bacause these data are without you personal information, thats the one chance ,,,please.....

Download leedroid noA2sd, boot in to recovery, mount the sd, copy the rom to the sd, unmount and flash the rom. You can use a other rom than leedroid if you want but for now just use it.

A possible solution here in post no.7:
http://forum.cyanogenmod.com/topic/6433-solved-messed-up-partitions-on-internal-storage/
Also I can do the thing you suggested to create the files , but since now I am not at home upload would take forever...
Also try first installing the NOA2SD LeeDroid rom.
+ What Rom You want to install? Does it need an ext 2/3/4 partition, maybe that's the cause, also make sure your SD is formatted to FAT32.

Yes I think its the fat, I try it home later.
The main problem was that we can't mount the SD could. Not mounted in the recovery ... I say it already at the top...

Yeah, you must make an ext partition on the FAT32 SD card, and it should work.

Can I make that with ubuntu?
Ok then I have two partitions on the sdcart (4gb).
On which partition should I have all my folders?
On which partition should I have my zip data (rom) ?
;D you make me hope
Sent from my Desire HD using XDA App

Your error is related to a missing ext partition, since the phone doesn't boot i assume you tried to install a sense HD rom. What it said a the top is mounting the ext partition failed, I'm talking about mounting the normal fat partition as mass storing to copy the rom onto the sd card. If that also does not work, take out the sd card put it in a card reader and copy the rom on to it, the put sd back and flash leedroid. This will give you a booting device.
If you want to make and use a ext partition make sure you first have the fat and then the ext3, all files should be on the fat partition and there is no need to do anything else to the ext partition.

I suggest using GParted for that or anything that works in Ubuntu.
If you have another Android device (i bet you have ) you can dowload ROM manager form the Market and use that to create partitions / format card (it is easier).
"Partitioning your SD Card ready for A2SD+
* Backup all data on you SD card (this will be wiped)
* The card should be formatted with your standard FAT32 partition 1st followed by an EXT2/3/4 partition
* Linux users use GParted or a similar software.
* For everyone else I would recommend using Rom Manager
* Once you have downloaded ROM manager from the market, open the app and click partition SD Card, Select your EXT size (512MB or 1024MB recommended) and set 0mb for swap
* Restore your data to your SD and the job is done."

Desire stuck in boot loop

Hello, tonight i tried some thing (i just wanted to change rom), but i made some mistakes... now i cannot boot my phone, it keeps rebooting. I have Leedroid ROM and it keeps rebooting after PC-boot like animation. The only thing i can access is the back button + power recovery. What can i do?
Thanks!

I have tried to wipe the cache and system, and solo deleted storage (hard reset)... but same point. I think that if i can put a update.zip on the sdcard i can flash it... but at the moment i don't have a sd card reader. Is the phone dead?

No your phone isnt dead
1. If you have a nandroid on your sd card just enter hboot and recover your system.
2. Otherwise you can perform an md5 check of the rom you downloaded and wish to flash. (just to make sure its not corrupted, i suppose your trying to flash leedroid) Enter hboot wipe everything >system wipe>cache>dalvic and then relash the rom. Oh and make sure your sd card is partitioned correctly ... a2sd, D2EXt ...
3. If problem persists go into hboot mount your phone as storage copy another rom you would like to try and then flash this, you can just follow the steps in no2 abouve again.
This should solve your problem!

The thing that i have done BAD is the format of the card... or better, i have done right things but i'm almost sure something was wrong. I formatted it from gparted, then created a 3GB FAT32 partition, and with the remaining space i created a ext4 partition. Then, i moved the files needed for the rom that i wanted to flash (MIUI) in the fat32 partition, as i seen that the ext4 part was mounted read only (dunno why).
IMPORTANT: I have done all this mounting the SD card via Clockwork recovery.
When i selected the voice "flash a zip selecting from memory card" (or something )... it said "cannot find a valid zip".
Then the only choice for me was to reboot and... that is
Now i cannot mount SD, as i don't have (at home) a SD card reader and i don't have access to CWM recovery.

[Q] Problems with Boot after replacing SDHC

Ok, I've searched everywhere and I cant find an answer so I've come here for help.
I've got a Telstra Branded HTC desire, been rooted and is running Leeroid 2.3 for the last month and its been great. Just bought a new 32gb SDHC to replace my old 8gb. Put it in my phone and detected it without a problem, was able to run "ClockWorkMod" to install a partition for A2SD "512mb ext, 0mb swap". Booted recovery, backed up, wiped the factory/data, Wiped Partition Cache and Wiped Dalvik Cache.
Now here's the problem
After all that is done I reboot from recovery mode, The phone hangs at the First Telstra Logo "The White HTC screen for original Rom". Take the 32gb SDHC out and put the old 8gb and it boots normally, take the 8gb out and have no memory and it boots normally.
Anyone know what the problem is? I've been re-installing the Rom on both the 8gb and 32gb, Re-Formatted the 32gb, copied all the files from the 8gb to 32gb and ran a full nandroid backup and still have the same problem........
While Restoring a copy of the backup from the 8gb on the 32gb, I got two things that are missing according to the check.
".android_secure.img not found. Skipping restore of /sdcard/.android_secure."
"sd-ext.img not found. Skipping restore of sd-ext/."
Spent the last 5 hours fiddling around with the phone but getting really frustrated, any help or a solution would be great
Thanks

It is definitely your SD Card.
However, a nandroid restore should work.
And from some reason you miss some files from your backup. The EXT.img is vital to make the ROM Run.
It does not even boot if you flash the ROM again after a full wipe?

When you mean full wipe, thats re-installing the rom from the 32gb SDHC or do I have to format something in Recovery Mode?
I donno why it cant find the EXT.img when I do the backup, if all fails I might as well throw out the SD card since its purpose was just for the phone......=_=
Yeah, a copied backup from the 8gb on the 32gb does the same thing, just hangs on the white splash logo thingy

Why not just wipe everything and start from scratch? Bit of a pain but if it works, it works.

I am willing to do that, the thing is whenever I put the 32gb card in my phone, it just hangs on the first set of logo's.
I've copied the Leeroid to the root of the 32gb, wiped the Factory/Data, Partition Cache and so on.
Go into install from zip and select Leeroid 3.2d.zip and run that. It finishes installing and asks me to reboot. I reboot manually and it loads the first set of logos and hangs.......
I've put the memstick in the phone and it worked before I partitioned it for A2SD. After that, its just been chaos, Im using the 8gb stick again so I can make calls an all but 32gb would be great to use =_=
If there's anyway to get this thing up and running on the 32gb. Doesnt matter if I have to start from scratch, as long if it works. That would be great ^_^

SD CARD = your 32 GB card
1. Partiton your SD CARD for A2SD+ (512MB Ext3 minimum)
2. Put SD CARD in the phone, copy Leedroid_a2sd.zip (or whatever it is) to the card.
3. In recovery wipe everything (data(factory reset)/cahce/dalvik cache) - dalvik is found under the advanced menu.
4. Install Leedroid 2.3
5. First boot takes 5-15 mins, so just wait.

I've got the 32gb SD Card working again, turns out that the partition I created on ClockWorkMod was corrupted. Rejoined the Partition, Wiped everything and installed Leeroid 2.3 and it works fine and the phone picks up the memory.
New Problem
I cannot get ClockWorkMod to create the partition since it automatically reboots the phone every time I attempt it and I get an black screen with an android/! picture.
Im using Gparted to create the A2SD partition but each time I create one I get an error
Unable to detect file system! Possible reasons are:
- The File System is Damaged
- The File System is Unknown to Gparted
- There is no file system available
- The device entry /dev/sdc2 is missing
I'm assuming that the SDHC I bought, for some reason doesn't allow me to create a partition? If that is the case, is there any work around to install apps to the SDHC. The Desire is such an awesome phone but it lacks the internal memory
nagypapi, I know I'm asking too many questions but your help means a lot

What card is it? If it was a cheap one, it can cause problems.
And partition it from the phone using GParted.
Boot into recovery, mount USB storage. And the run Gparted.
Remove both partitions, and create new ones from scratch.
If GParted still gives an error, try to format it on the PC.

I bought the SDHC from eBay, doesn't have a brand but it works apart from the whole partition thingy.
I got the error when I format the SDHC on the computer with card reader, I'll have a go with the USB Storage on the phone recovery mode. Donno if it will make a difference but I'll give it a shot anyways, I cant do it now since I have work tomorrow but I'll attempt it while I'm working and get back to you

Sounds like a defective card, send it back, if possible. Never use "unbranded" cards.

fix "can't mount /dev/block/mmcblk0p2 (File exists) error mounting /sd-ext/!.

I flashed a Leedroid 3.0 and it was just stuck in the boot screen. So tried to clear data and all thru recovery and i got this error "can't mount /dev/block/mmcblk0p2 (File exists) error mounting /sd-ext/!.
I downloaded gparted to repartition my 8gb sd card. I did a ext3 partition. When i plug back the sd card, the error still comes out in recovery mode. Any rom i flash gets stuck in Bootscreen still. I tried partitioning my 4gb sd card but it also gave the same error in the recovery.
please help. Been trying the whole day and still nothing is happening

Have you tried partitioning it through recovery? (If you have that option available)

I'd begin with reflashing a cwm recovery, cause maybe the problem is not your sd. In "mounts and storage" did you try to mount/amount sd-ext ?
Sent from my Desire using LeeDrOiD 2.4.1

I cant also mount/unmount sd ext. It says the same thing. can't mount /dev/block/mmcblk0p2 (File exists) error mounting /sd-ext/!. should i just buy a fresh new memory card?

What exactly is your recovery ?
Sent from my Desire using LeeDrOiD 2.4.1

flash clockworkmod recovery 2.5.0.7 . Im using a sd card now without partition. It seems to work with the rom. Using Leedroid 2.4.1 . If i use the original SD card and reboot it with it, its just stuck in HTC boot screen.

So you should just use parted again with your stock sd to make it work ...

Common error when card is not partitioned or wrongly partitioned. First make Fat, then make EXT.
http://forum.xda-developers.com/showpost.php?p=7279872&postcount=3

Thanks man. I was able to repartition. I made a wrong partition in gparted. Made a fat32 primary then the second one extended partition. From your post i made it primary also the second one. Now my rom reads the sd card. Thanks again.

Hmmm I had this exact same problem with LeeDroid 3.0.2... Trying to flash without wiping, had about 80 apps on my EXT3 partition... Got stuck on the white HTC screen for about 2 hours, gave up, pulled the battery, tried to flash the alignment zip, still stuck... tried to restore nandroid backup but then started getting this same error as you.
Thankfully was able to rescue all files from my SD card, format and partition again, then flashed LeeDroid 3.0.2 and restored a Titanium backup... everything running smoothly again! Phew...

May I ask how did you manage to do that?
EDIT:
Ok. Apart from the backup/restore issues that depend on having a healthy ext partition as I figure, the "can't mount [..] error mounting /sd-ext/!" problem is responsible for the "green HTC logo on the white screen freeze" also. So I've been trying to make it work all evening and this is what I found:
The Error (at least in my case) and the freaking "green HTC logo" freezez were generated because the Ext partition got corrupted in some bizarre and mysterious way. I have no idea how that could have happened, but I guess a small role in this ballet got played by the ROM itself and maybe even the nandroid backup built into the CWM (ClockWorkMod). It started right after I finished installing a fresh copy of the LeeDroid 2.4.1 and all my favourite apps (which worked flawlessly), rebooted into bootloader > CWM > nandroid and made the full backup of the system. Rebooting the device afterwards got me into the above mentioned freeze.
I tried many things, among which were flashing different ROMs and Radio images (without wiping though), but none worked. I just wanted to roll back to the previous state (because i've spent quite some time configuring and installing the 2.4.1) and it seemed impossible at that point. Browsing the recovery options got me into the Mount and storage section where I noticed the listed error with the ext partition. I thought maybe formatting will help - well, it didn't. After a couple of weird things I had tried, I've decided I should delete the ext partition (leaving just the fat32 intact). Creating a new ext partition from scratch seemed to solve the error. However this didn't solve the freezing. And the reason had to be the fact that when it created the nandroid backup images, the ext was already corrupt (or however unreadable), so the relative image was not written because it didn't see the source.
I doubt there is any way to fully restore my previously installed ROM with all of it's apps in place and in a functioning order, because the ext partition had data on it and now it's missing (hence the freeze).
Therefore the question: what could have gone so badly wrong to compromise the ext partition?
And another one: is the LeeDroid 2.4.1 ROM or the 2.5.0.7 ClockworkMod Recovery the culprit?
Sorry for the looong post. I look further to hearing from Lee, if his busy schedule allows it and thank him in advance.
Cheers!

hi! having the same exact problem right now... could you please help me how did you rescue all of your sd-card and sd-ext partitions? Thank you very much!

same problem on my N1, reparition to resolved

hi..
i got this problem too
i have clockworkmod recovery. pvt4.
cyanogenmod 7.1.
didn't make any partitions,
everything is by default as i got with cyanogenmod
s-on.
sd - 8gb, class2
yesterday my desire freezed.so i had to pull out the battery. but i couldn't turn it on till' i didn't wipe cache and dalvik cache.
When i selected wipe dalvik cache i got this
E: can't mount /dev/ block/mmcblk0p2
(file exists)
but it wiped it and my phone worked.
this appears even without sd card
it freezed after a week again but after a couple of reboots it works again but the error still exists.
i am newbie so i don't know what to do?

So I flashed a ROM which stuffed up my partitions somehow (also became S-ON, WTH?!).
I got 'can't open /dev/block/mmcblk0 (or /dev/block/mmcblk0p1) (invalid argument)' when trying to mount /sdcard.
I also got the aforementioned 'can't open /dev/block/mmcblk0p2 (file exists)' when trying to mount /sd-ext.
After literally 16 hours of head banging, I realised when I partitioned the SD card again that they were logical instead of primary. Partitioned using minitool partition wizard home edition.
Rundown:
I'm using LeeDroid v3.3.3 with clockworkmod recovery 2.5.0.7
Make sure you partition FAT32 first as primary, then ext3 as primary. LeeDroid says to partition ext3 1GB after FAT32, so e.g. my SD card is 16GB, I have ~13.8GB FAT32 | 1GB ext3
This fixed the 'can't mount /dev/block/mmcblk0' error, /sdcard is mountable.
You can now run .zip files from recovery (yay!). Throw alignment_ext3.zip on there and run it. You should now be able to mount /sd-ext.
Do a full wipe + Dalvik cache wipe (to test /sd-ext accessibility). For me it was back to normal and I'm currently doing a restore.
Always do a backup.

[Q] Sd card problems

Hi guys, sorry for the newbie question but here I go. Just now I decided to flash a new ROM so I do what I normally did before I flash a new ROM (backup my sd card contents and do a nandroid backup). After I done those, I reformat my sd card using my laptop and place the ROM I wanted into the sd card. After I flash the ROM I get stuck in the HTC screen and my backup doesn't work but luckily I manage to revive my Desire. After that I notice that my previous partition that I made using gparted is gone and that's why the ROM didn't work at first. So, am I still able to recover my lost partition from my sd card or they are gone for good?

If you have a working nandroid backup, you can try to recreate your partitions first and restore then.

Windows laptop? The reformat using will have wiped your Ext partition. As said recreate fat32 and Ext using Gparted and restore nandroid (assuming under AmonRa or 4Ext recoveries you included sd-ext) or flash new Rom.

Although I'm not an expert in partitioning but I can provide some info about this. Firstly, how you partition your sd card (gparted, rom manager or other methods)? And which partition you made (EXT3/4)?

The ext partition itself is gone, but if you re-partition using Gparted, copy your sd card backup from laptop onto sd card, then providing your nandroid included sd ext backup a restore should get you back to where you were.
