[Q] Clockwork...DesireHD...NAND...Ext4-SD? Arrrr

OK, not that much of a noob (or at least dont think I am!) have been playing with android for some time, and have decided to cook up my own rom based on DesireHD. After some failures I now have a good stockish rom that I like and will release once i can sort out a few problems that I have.
I want to go down the CWM .zip route so I can release updates easily, off to the forums I went with a few questions... hours and hours of searching and researching and a few test runs later... have even more questions!!!!
1. EuroHD2 (Leo512) has 512mb ROM > how much of that ROM is actually available?
2a. When does the kernel load the SD-Ext partition?
2b. With CMW Recovery do you have to set a "userdata" partition when using SD-Ext data, or can you get away with not setting one?
3. Does CMW support using SD-Ext userdata
4. Is the 400m CMW Recovery only for the Leo1024?
5. What is the maximum size for the "system" partition on Leo512?
6. What is with all the questions??????
As you can see, many questions. Most have come from searching the forums and becoming more and more confused with it all!!
Please help!

All of it.
Partitions:
misc 1MB
recovery 5MB
boot 5MB
system 150MB to 350MB
cache (optional, but people like 10MB)
userdata (whatever that remains, 350MB system partition size = 50mb userdata)

yes, sadly, you still need the userdata partition, you can go around it by creating another partition on the SD card, and call it userdata, I am assuming that works too. So now your SD has userdata, sd-ext, fat32 partitions.

urm, that's not CMW's job, that's your job.
You can either use DATA2EXT method which puts all userdata in SD card, ext2/3/4 partition or A2SD+ which puts all your data on the SD card, minus I don't know what, because it keeps reducing and I never figure out what. I am lazy to use adb.exe to go check.

Yes, because you really ran out of space. 350MB system partition, gives you less than 50MB of userdata partition provided you have 10MB of cache partition.

I was wondering that...
So if I create a "userdata" partition on the SD card the system should use that... meaning no userdata partition on the NAND... meaning SD-Ext and Data2SD features are not needed?
But then surly if it was that easy somebody else would have done it?!
The layout I am thinking is:
NAND/
--/misc (1mb)
--/boot (5mb)
--/recovery (5mb) *Is this needed? - Is this not for the recovery programs that we have on SD?
--/system (350-400mb) *theoretically upto 491mb as no userdata on NAND
--/cache (10mb)
SD/
--/userdata (1gb) *Could be bigger, but have read that it can cause corruption if over 2gb
-Fat32 (leftovers)
But all of this comes back to Q2a. When does the kernel load SD partitions?!
Other idea is to set the "userdata" in NAND to set size and grow the "system" partition and carry on using SD-Ext and Data2SD for internal storage, something like:
NAND/
--/misc (1mb)
--/boot (5mb)
--/recovery (5mb)
--/cache (10mb)
--/userdata (50mb)
--/system (leftovers) *441mb
SD/
--/Ext (1gb)
-Fat32
But then does the "system" partition have to be created 4th and wont work if created last???? And what about all the plastic trees, where do they go?! My head hurts, i'm cold and there are wolfs after me!

I am guessing that creating userdata on sd card might work, but I don't know how your build mounts partitions, so that is your job too.
but you should read up on data2sd, data2ext, a2sd+ and a2sd
No, you can move the partitions around, it worked for me.

why some Roms needs the SD-EXT partition ?

Hi all,
why some Roms needs the SD-EXT partition ?
if we install a rom using the SD-EXT partition and then we boot without putting the SD card,the phone will boot?
many thanks

There are to ways a ROM can use the partition.
1. It will put your apps to sd which saves much space and you can install nearly infinite count of apps
2. Put dalvik cache to sd card which saves also space /ram etc.
If it just uses the partition for putting apps on sd it will boot but if it uses dalvik 2sd it won't boot.

(Just to add)
but none of the apps you installed will be there.

thank you jonas2295 and samsamuel,
and what about the sense roms?it puts apps or dalvik cache to sd to sd ?
i'm interested to these roms: sense 2.1 and sense 3.0

Try this one (Sense 3.0):
http://forum.xda-developers.com/showthread.php?t=1185087
It´s from the best dev in know and it uses dalvik2sd and a2sd+ .
No glitches and the dev knows what he does.

i have only 1Go sd card,so can i install this rom and use 1Go ext partion? if it is possible,can i use my sd card after installing the rom?
CWR: 5/180/5 ==>what does this mean "5/180/5"
i know that 180 is the size for the recovery,and what about the "5"?

hmm that´s bad .no you won´t be able to use it .
Or at least you can´t put anything on sd.
You need min. 2gb card.

eiy seems like AOKP but using HD2Toolkit, min. for cache is 5mb, try the link below it could give you an idea

Installations:
Please use at least 170MB system partition and at least 2MB cache partition.
Please refer to ksubedi's HD2 NAND Toolkit and/or mskip's guide.
Cache partition (/dev/block/mtdblock4) is only mounted and used by CWM.
Cache partition size is not important because the data partition (/dev/block/mtdblock5) is used as the cache space when running Android.
If your HD2 has bad NAND blocks, you may need larger partitions.
Wipe
Wipe Data/Factory Reset while doing a fresh install. (Optional: also delete /sdcard/Android folder or format your SD card if you have any strange issue.)
Advanced -> Wipe Dalvik Cache while upgrading from an old version and wanting to retain data.
Flash this ROM.
I click custom and below that enter 2 in cache box, click repartition. Show new table "What do you want the custom partition size to be 5-445 MB allowed. I write 170 click OK.
I give table sorry chase size must be 5 to 45MB.
Where is I did mistake ?

1 -In the main HD2 android NAND toolkit window, look left for "Choose system partition size(MAGLDR)" and select "CUSTOM"
2 -Below this window change "cache size", but smallest possible is 5MB. It doesn't matter if it's bigger, won't give trouble.
3-after those step choose "Repartition" button below 'Functions' and type desired (4) system partition size.
Have fun.

as retsam88 said, it deoesnt matter the cache size, most people leave it at 5, some roms say 45, (but i haven't seen that for a while).
As far as i know, (i've read it once or twice) on most roms, only recovery uses the cache partition.

misc ya 1M
boot yboot|ro 5M or 6M // According to their Recovery
system ya 150M // Minimal Installation
system ya 240M // Full Installation
system ya 150M - 275M // Custom Installation
cache ya 2M
userdata ya|asize|hr allsize
if you have Bad Sectors, please add 5MB more, to System Partition
I like to do this partition. What do i have to make it work with hd2toolkit ? Thanks

you cant because the toolkit writes a new flash.cfg each time when you choose custom, or uses an .nbh when you choose a preselected size.
You should find the daf.exe flash version of cwm, and when you extract it into a folder you will find one file called flash.cfg, , open that in notepad you will see a list like teh one you posted, , edit the numbers, save it, then run daf.exe with teh phone in usb flasher mode.

-< Partitioning Questions >-

OK .. Im about to flash a new rom (ParanoidAndroid HD2) but i am a little confused on how to do all the partitioning requested.
Heres an example:
misc ya 1M
boot yboot|ro 5M
system ya 200M
cache ya 2M
userdata ya|asize|hr allsize
I understand that i can use HDToolkit to partition the system and cache, but what about partitioning "boot" and "misc". And what is userddata ya?

Everything in that list gets partitioned when you do the system partition, so don't worry about it.
Also, your thread title says SD partitioning, which is nothing to do with anything in your post,, totally different thing.

So basically all i want to do is make sure the system partitioning is as recommended or enough and the same with the cache. The other partitioning is done during the installation.
If thats the case, thank you very much for your input.

Basically yeah, just select 200MB in the HD2 Toolkit and let it do it for you.

1.misc is for android misc data and boot is for the linux kernel and ramdisk in order to let the rom boot
2.normally we set boot to 5 and cache to >=2 because roms now dont really use this partition for cache, it's just used by cwm
3.misc and recovery should normally be 1 and 5~6
4.userdata is for android to store your system and application data in your daily usage
5.usually you can find an instruction for partitions size in a rom thread
EDIT:userdata is usually auomatically sized becasue it spreads at the end of the nand,
following other partitions...

[Q] why error in install 2.3.5?

Hi, I dont know, where fail me, please can you help me? Sorry if I write in bad section.
I want install this ROM to HTC HD2: http://forum.xda-developers.com/showthread.php?t=1348922 I found step by step guide, and stuck at at instal magldr 1.13 recovery, I solved that, and next step was instal CLK 1.5. ok, after reboot I get to android recovery menu. I copy ROM to root SDcard a over recovery menu installed , by instal asked me at wipe (I gave wipe) next ask was version EU vs US t-mobile verzi (EU option get error. US-tmobile get install ROM) last ask was magldr or CLK installed, I installed at last CLK so choiced CLK.. on LCD I saw install complete, you may reboot, and may take 15 minutes. I saw HTC logo, but after 35 minutes in stuck htc logo, I powered off and find help. can you help me, where I failed? THX and sorry for my bad english

Follow the guide in my signature, either you followed a very bad guide or (more likely) you misunderstood a lot of it because of the language barrier. This is an outline of the steps you should be taking:
1. Install HSPL
2. Install a compatible radio
3. Install MAGLDR
4. Install CWM with the correct system partition size for your chosen ROM
5. Partition your SD card for A2SD (optional)
6. Install the ROM
7. Install any extra features you want.
Good luck

That is correct, yes, however you must also partition your SD card if you have an EU HD2 as some apps will be installed to the EXT partition of the SD. You can either do this on a PC or in CWM (see the guide in my signature for this).

How can I check if I have EU or TMOUS (this is not my phone, so I dont know it)? I am installing TMOUS, because EU install get error. and must I EXT partition creat in SD with TMOUSE? big thanks

A TMOUS HD2 will have the T-Mobile logo on the top of the phone, a red end call button and a green call button. I think that you may still need to create an EXT partition for the TMOUS one as well, now that I've had a look at the ROM.

I changed touch screen, so mabye only check button ok I think I have EU version, so I need EXT part? can you any PC tools recommend me? I think by CWM not work :/ or its possible it take format 8gb card 1 hour? I see only partitioning SD card... please wait... but really I see it 1 hour :/

Yeah, it shouldn't take an hour so it's clearly not working properly in CWM. I'd recommend using EaseUS Partition Manager, it's fairly user friendly. I don't know about the language settings though, hopefully it'll work for you.

I must be idiot :/ still nothing I formated SD card with primary partition FAT32 capacity 6,5 GB and 1 logical partition EXT (I tried EXT2 and EXT3), but If I try install EU version, by step "mount sd-ext" get error E:error name_rom.zip (status 0) isntall aborted. Any ideas? THX

OK, I choosed another ROM and it work BIG THANK TO Nigeldg
