Root Htc Desire root problem

Hadron Give Me link for All Things Root Guide sticky post ???

i have read many forum but don't get idea about ext partition ??

how can i remove 4ext recovery and get old screen of recovery it has to much option and some times i am confused what to do so plz tell me about it ???
 
I don't think you really want the "old" recovery if you mean the original stock one (pre-root) - that doesn't do anything useful (doesn't let you take backups, flash ROMs, or anything really apart from wipe data and apps).

Any other custom recovery has a similar number of options, though they may be laid out differently.
 
MildWild Oxygen will be fine. It will run Ok without the partition, just you'll have more storage space if you do add one. I'd probably go with MildWild rather than CM7.2, as CM will need more setting up.

If you want to partition it, you could use 4Ext recovery to do so. I don't usually recommend using recovery to partition a card, but trust 4Ext more than ClockworkMod or Amon Ra for partitioning. You want to add a single ext4 partition, if you are just using it for apps then 0.5GB to 1 GB would be fine. Back up everything on the card to a computer first though (including folders with names starting with a ".", like ".android_secure" - make sure your file viewer is set to show hidden/system files), because partitioning often erases the card.

If you've already installed the ROM, you may need to go into menu (Settings->Applications->Development) to activate a2sd - don't bother with data2sd stuff. If your space doesn't change after partitioning, try looking at the settings there.
 
to change my rom my system partition will ok or i required to repartition it ??

and if i don't like the rom and want to try current rom again what i have to do ??
i mean at flash time we select rom zip file from recovery but our back up is not zip file and not consist boot image file so it will restore ???
 
A card partition will be ok with any ROM.

If you have changed your system partition (flashed a custom hboot) you may need to change it again if you change ROM. The system partition must be large enough for the ROM. If you have not done this then don't worry about this.

Make a backup from the recovery's backup and restore menu before changing ROM. If you want to revert you go back to recovery and select "restore" to restore the backup.
 
Sorry, but it's better if you tell me what you did rather than that you followed some instructions from that thread. There are many things in there, and I need to know which ones you did and in which order to be sure whether things were done correctly.

What you should have done is:

* taken a backup from recovery
* wiped the phone (wipe data/factory reset should do everything in one go, and should be all you need)
* install zip from sd card

That should be all that's needed. However, if you have a blank card I'd advise doing a titanium backup first, and backing up contacts and messages (if the card is blank, it does not contain those backups).

The other thing is, if it hasn't worked what actually has happened? I think you are saying that it is booting back to the original ROM, i.e. that it's not flashed the ROM at all. If so, what messages did you get when you tried to install the ROM? And are your apps/data still present, or just the pre-installed system apps (if you've wiped it should only be the pre-installed ones)?

Sorry for all of the questions, but I need more information to work out what has happened.
 
I have done backup in other SD then using 4ext I do wipe data /factory reset
Then wipe delvic+cache
Then install from SD and then select mildwild.zip .
Then no error only it show installation start..
Installation aborted...
Then I start there are only system app no other app .
 
No other message, just installation aborted?

One possibility is that the ROM zip isn't a good copy. You could check the md5 if they provided one, or download another copy. This is the less likely in my opinion.

The other thing is that maybe you have "signature verification" turned on? To test this, go into the "Install from sdcard" menu and select the item "toggle signature verification". It will respond saying either "Enabled" or "Disabled". You want "Disabled", so if it says "Enabled" select it again. When it says "Disabled" then try flashing the ROM again.
 
Ya there is no error only start and aborted...

My 4ext still display "ATTN: recovery is in safe mode this is because the following partition is not accessible :"system" please enter the wipe menu and format system ! if you changehboot you should choose to format all partition (except sdcard) After words please reboot recovery "

Any problem is there ??
My other steps is ok I mean wipe data /factory reset Then wipe delvic+cache
Then install from SD...
 
I don't think you even need to wipe dalvik after a factory reset - factory reset alone should be enough (though it will do no harm).

Try just rebooting recovery and see whether the message goes away. If you are unable to flash the ROM you could try formatting system, but I'd avoid that if you can - try rebooting recovery, then check the signature verification toggle and see whether you can flash the ROM. If it still won't let you you could format system - you need to flash the ROM or restore backup after formatting system, because formatting system erases the ROM.

Still same message in recovery...

if i format system then 4ext remain or it will also removed ??
if remove then how i backup ROM ???
at that time if i direct install Mildwild Rom from SD it will work ??
 
DONE .....
Very very grate full to Hadron Thanx a lot man.....
yupeee i have installed MildWild V-4.3 it takes only 5-10 min...
The notice in recovery also gone....
 
Phew - relief! :D

I was wondering whether we'd have to discuss fastboot flashing another recovery as the next step - glad not to have to do that!
 
7gb main partition followed by 1gb ext4 partition, (no swap) make both primary. Use gparted or 4ext recovery to do this.
 
The first bit of advice: partitioning usually wipes the card, so back everything up to a computer first. Make sure you can see system/hidden files and copy those too - ".android_secure" in particular (that's where apps moved to sd are).

Having done that, we have generally recommended GParted, but to be honest I think that 4Ext Touch recovery can probably do this fine - it uses a different partitioning utility to older recoveries, and includes the ability to check for partition alignment (which is the thing that most recoveries get wrong when partitioning). So that might be the simpler way of doing it.

So, back up the card, boot into recovery, and you'll find the option to partition the card in the "tools" menu. I'd add a single ext4 partition, no larger than 1GB (for a2sd that's as big as you'll ever need), leave the rest as fat32. You can then copy the card contents back to the fat32 partition afterwards.

There is an option to partition and preserve your data ("save my fat32"), which may be worth a try, but if there are any problems you'll need to use the other option, which is why it's important to back up anyway.
 
Edit - Ignore this post.

Hboot is the system partition.
The part where the rom sits.
Smaller hboot means more space for apps.
 
I used 4Ext to partition my card, was too lazy to boot a pc into GParted and 4Ext was on the phone. All went well and smooth. Do back up the SD card before doing any of this though.
