Here is a tutorial. Stay away from windows partition makers. http://forum.xda-developers.com/showthread.php?t=1016084
Basic rules: Fat partition comes first, both have to be primary, respect file-system and partition sizes indicated by the developer of that ROM.

[Q] Can anyone please suggest or help on what to do in my situation?

I recently followed the video noob guide on rooting my desire and installed the Leedroid 3.0.7 rom.
Everything was working perfectly until recently my phone started to freeze and the only option was to remove the battery to switch it off. This kept on occurring more and more often and now it refuses to go past the splash screen. It is just stuck there until the battery dies.
The bios works so i went there wiped data/factory settings, wiped cache and dalvik cache and installed the newer leedroid 3.0.8 rom. It installed without errors but still after reboot doesn't go past the splash screen.
Does this mean it's bricked? and what can i do make it work again?
More info:
It's the amoled unbranded htc desire.
I did all the steps in the noob proof guide here on xda including the custom splash screen.
Bios info:
BRAVO PVT1 SHIP S-OFF
HBOOT - 0.93.0001
MICROP-031d
TOUCH PANEL-SYNT0101
RADIO - 5.11.02.27

Did you follow the steps and create an EXT3 partition on your SD card and align it before flashing the ROM?
I have a 4gb card, i created a 3gb fat32 partition and a EXT4 1gb partition
basicly everything was done 100% same as in that guide
The first page of the 3.0.8.2 LeeDroid ROM says to use and EXT3. It probably doesn't recognize EXT4 partitions. I'd start with re-formatting your card, aligning the partition then flashing the ROM again.
thnx i will try that
I need a working phone to use gparted, don't I? I can't enable usb mode from bios or anything
P.S. If i use my friends xperia with my sd card in gparted will the partition work later on my desire? thnks

no you dont need a working phone to use gparted. if u can or want to, connect your sdcard via usb or some sort and use gparted to partition it.
if i were you, i'd flash AmonRA recovery. you'll be able to partition your sdcard and format it to ext2/3/4. no need to connect to pc to partition it. hassle free.
well i got a card reader made an ext3 1gb partition, still same problem when it doesn't go past the splash screen. tried leedroid and reflex s roms.
any suggestions?
how do i go back to stock from this point?
If I were you I'd try a different ROM. THE absolute most stable, most worked at, and most widely used is Cyanogenmod, and personally I have never had any issues with that. It is an AOSP (Android Open Source Project) ROM, so you don't get HTC Sense, but you do get a lot more in speed etc.
If you're looking for a good sense ROM, I'd recommend RCMixS, or Cool Sensation V6 (If you don't mind your phone being a little slow for looks etc.)

[Q] Rom not installing

Hi
I have a Desire GSM rooted and S-ON RA-Desire v2.0.1 stock HBOOT Ext 4 1Gb latest radio ends in 23
Have been running on a custom rom for over a year now and want to install the latest copy of the same rom. The md5sum is identical for the zip file to the source.
Booted into recovery wiped all data, cache and then devlik-cache.
I have turned off signature verification and then selected my rom zip on SD card.
Installed the rom rather there were no errors and it took about 20 seconds (seemed too fast).
Next in recovery I did a reboot.
Now the screen went white with green HTC logo in centre for about 1 minute then after this a black screen with android written logo for about another 2 minutes.
Eventually phone boots into rom but it is not the new rom it is the exact same old rom.
I can see from applications listed that I am still super user so not lost root.
In settings software information everything is listed identical to what I had before.
The contents of the zip files are different so it is not the same rom being flashed.
Choosen rom is
[ROM][Cool Sense][5 April]Cool Droid v3|2.3.4|FASTEST|Data++/Stock (currently have Icecream sense v2 installed which is an earlier version of the same rom)
I did not install the alignment zip as I had already setup to use an earlier rom version and ext4.
What have I done wrong in trying to install my choosen rom please?
I feel like I must have missed something.
Not sure which recovery you have, with 4ext I boot to recover, format everything except sd then install zip and it seems to work, obviously everything then needs reinstalling from the backup you'll have made

Hi
Unrevoked 3, as I have one of those odd PVT4 Desire phones 4000 erase size using RA Recovery. (something like that sorry if technical references are not super clear).
I use Titatium backup so reinstalling wont take long just need the ROM to install.
This is a fast glitch free rom using sense so I do not want to try a different rom as it gave me a year without trouble. Only doing this to start again with the space issue needing a refresh.
I have cleared delivk cache again and flashed my original v2 rom and that worked showing expected progress reports.
So I thought would try flashing the new v3 rom, and see if I got any joy this time.
Still no joy, it looks like it starts as two lines appear then it says complete with no obvious error.
So I reflashed the original v2 rom again and will go with that as I need a phone more then I need to play.
Odd.
Maybe the new v3 rom needs sOFF but as far as I could read it does not.
Even installing the previous rom things are still not right.
The apps that normally come with the rom are not installed such as Demon controller, No adds and Busy Box. I can see that they are in the zip file they are just not been added.
I can manually install Busy Box from the market so I know it is not a permission thing.
Titatium Backup is seeing my Ext4 partion (it calls it an ap2sd but it is showing) so I don't think there is a problem with my SD car arrangement.
I stupidly do not have a nandroid of the previous install I can restore.
So any ideas please why the previously working and installed rom is not reinstalling fully with all it's built in apps?
Anything I could try please?
Looks like I have identified the problem, my SD card is flakey and Gparted reports sick partion table that wont fix so the Ext4 partion was not been seen which is probably why the install failed and the apps were not installing.
New Sd card will be ordered and then start again.
Thankfully I dod have an uptodate SD card backup.
Phone is working just as a phone for the next few days.
These micro SD cards do not last long at this rate I get 1 year from them as this will be my third ordered.
Go to S-OFF, is better and mandatory for a lot of rom.
New card and more fiddle work with Gparted and now waiting for setup to complete as old v2 rom is installed. It works fast and is smooth plus has HTCsense so I can keep my sync capability so will be staying with it so I can live without S-OFF
Gparted when I followd the recommendations I kept getting a corrupt card on my phone so this is what worked for me.
Format card on phone
Then put card into usb card reader and place in PC
Reboot PC onto Gparted CD
Select SD card and then I resized the fat32 partion already there and then added a new EXT4 partion.
This worked for me.
Dump gparted, format the card through 4ext recovery

Bootloop issue

Hi,
I have rooted, unlocked bootloader and unlocked sim on my friends Desire, but I have tried flashing several Roms. They at first appear to be successful, they boot happily but with every ROM (Ive tried 5) on second boot it gets stuck in bootloop.
Anyone got any ideas?
Thanks
Need a bit more detail:
- Unlocked bootloader using 'revolutionary' to S-OFF?
- What ROMs are you trying?
- Are you performing a full wipe before you flash any of them?
- Do any of them require an sd partition? If so have you correctly partitioned your sd card using 4EXT recovery or gparted (not minitool or CWM recovery)
Ive tried Mildwild stable, Mildwild 5.0, Touchwiz 4.2.2, and two others I cant remember. Ive done everything you say apart from Ive partitioned using CWM.
Maybe thats it!
Yes that's it. Cwm creates badly aligned partitions. Those Roms try to move bits to the sd-ext hence bootloops
- you're s-off, flash 4ext recovery through fastboot
- backup your sd, then partition your sd card using 4 ext.
- you will gain more app space for some of those roms by flashing a compatible hboot using fastboot. Check each rom thread for individual requirements

Sorry your question doesn't really make sense.
'Revolutionary' is merely a method to unlock bootloader (s-off), has nothing to do with ROM compatibility.
If you're referring to CWM (clockworkmod) recovery, you should still be able to install ROMs with it as you have discovered. However it is not suitable for partitioning your sd card.
So in your current position, you should be able to install a ROM with CWM as long as it doesn't need an sd-ext partition. However:
- Most ROMs require a partition
- You won't be able to install many apps without a partition.
You are s-off, so this gives you the power to do two things:
- change recovery -> 4EXT is better, will partition your sd card correctly
- change hboot -> allows for more optimum use of the Desire's actual internal nand memory (more space for apps).
Basically I recommend you find the guides to learn how to flash both using fastboot. Then you are in a much better position to install a ROM without issue + app space :good:

It can see CM 12 backup because I have put them into the zip file. So when u flash the zip the backup will automatically extract to correct DIR...
That dual boot system different. That was have only one system partition. And My one have 3 new partitions. On that system I tried lot of times. But sometimes not get worked. I don't know why... Maybe my fault. I have tried CM 12 on that. On that u said guide I cannot switch back to other rom after installing the CM12 untill format the system... My one have New recovery. So Your phone will get two recovery modes. And much more...
That's why my Dual Boot system was different from that guide.

Why not just thank a developer for doing something that you neither have inclination nor the calibre or the talent to do or understand. Why not just say "OK cool...dual boot system...nice..I'll try it out..maybe I'll see something different from the 'thread already posted there'" instead of *****ing about it and asking for explanations like you own this forum!

Table will be Like this
Second Rom System Partition = mmcblk0p30
Second Rom Data Partition = mmcblk1p2
Second Rom Cache Parition = mmcblk1p3
