WM5 Memory Map

Hi guys (and gals)
First, thanks to c_shekhar for the Himalaya WM5 roms. Top Job
I'm quite new to WM5 and it has taken a little while for me to work out
how the XDA memory usage has changed from older PocketPC versions.
I thought I'd share how I think it looks for others, like me, who are using WM5
for the first time, thanks to the great ROMS on this site.
I've probably got bits of this wrong. Feel free to correct me
1st we need to understand what memory is in an XDAII:
128MB RAM (non-volatile after soft reset | volatile after hard reset)
32MB Flash ROM - Integrated with CPU (non-volatile after soft or hard reset)
32MB Flash ROM - Disk On Chip (DOC) (non-volatile after soft or hard reset) *
* All or part of this will get formatted if you select YES on the FORMAT STORAGE option on hard reset on WM5
The 32MB DOC Flash Rom is divided into two 16MB partitions by default:
Half goes to extROM
Half goes to persistant storage
Pre WM5 the memory map looked like this:
PRE WM5 - MEMORY MAP
--------------------------------------------------------------------------
...................| Storage (Installed Program Files, My Docs etc
128MB RAM.| Programs (running apps)
...................| Pocket PC OS (i.e. running state)
--------------------------------------------------------------------------
32MB Flash / CPU..| System ROM (i.e. where the ROM .nbf goes) (/Windows folder?)
--------------------------------------------------------------------------
16MB Flash DOC.| extROM (hidden by default. Contains vendor specific apps / hard reset - system startup)
16MB Flash DOC.| Persistant Storage (/Storage folder on pre WM5)
--------------------------------------------------------------------------
Pre WM5 pocketPC versions allowed you to dynamically select the amount
of (non-persistant) storage / Program space via the memory applet. Obviously
a hard reset would lose any programs installed into this RAM area of memory. Also the file system had a /Storage folder so you knew where to put impotant files that a hard reset wouldn't wipe out.
Things have all changed with WM5. Thus: (Based on c_shekhar 3.50a ROM)
WM5 - MEMORY MAP
--------------------------------------------------------------------------
...................| 37MB Programs (running apps)
...................| 40MB RAMDisk Storage (Non persistant storage /RAMdisk folder)
128MB RAM.| 24MB PagePool (PocketPC OS Cache ares (?))
...................| 27MB Pocket PC OS (i.e. running state)
--------------------------------------------------------------------------
32MB Flash / CPU | System ROM (i.e. where the ROM .nbf goes) (/Windows folder?)
--------------------------------------------------------------------------
16MB Flash DOC.| extROM (hidden by default. Contains vendor specific apps / hard reset - system startup)
16MB Flash DOC.| Persistant Storage (14MB Formatted space)**
--------------------------------------------------------------------------
** WM5 no longer has a /Storage folder. Now /My Document /Program Files etc
reside in this persistant area
Obviously one benefit to this re-arrangement is that a hard reset does not wipe
out your installed program, assuming you don't FORMAT STORAGE in the WM5 hard reset screen.
If you are using c_shekhar's ROM then the extROM area is not used. In fact its
probably is sitting there invisible to you with the old pre WM5 vendor apps wasting space. There are tools to make this 16MB partition visible and merge it into the existing 16MB DOC partition to give you 32MB of persistant storage.
Instructions >here<
To check how much storage space you have:
Start>>Settings>>System Tab>>Memory
Storage Total will be circa 14.60MB for standard Install
Storage Total will be circa 30.53MB for merged extROM modification
There are also ways to change the size of the PagePool and RAMdisk but they are not discussed here. Search for c_shekhar + PagePool + RAMdisk
I hope this has been helpful
Please post any corrections, or further useful info

very helpful indeed
thanks for all the research

Sorry to ask you silly questions... I am a newbie about PDA. And I stil didn't understand clearly concerning why extROM exist in PDA.
1. What is the real function extROM ?
2. I read from your writing, If I used c_shekhar rom it means extROM doesn't have any function anymore. Is it true ?
3. What are the risks if I merge extROM to storage ?
I hope you would like to be kind to explained this for me.

Well..

...again I could be wrong here, and c_shekhar would know more about his ROM, but I think the general idea was:
1. XDA Manufacturer (i.e. HTC) provides main system ROM i.e. the pocketpc OS
2. The network supplier, or distributer (e.g. O2) provide the extROM ROM
Then when you hard boot the OS loads and autoruns and installs the branded
applications from the extROM to give you a clean branded install after a hard boot.
The extROM is readonly and invisible so you don't mess it up and can always
get back to the standard installation O2 or other supplier provided in the box.
My understanding is it is only used during a hard boot to install branded apps.
If you decide to install a ROM like c_shekhar's then he installs all the software
you need into the main system ROM. He doesn't use extROM to provide any
other applications that would install on a hard boot. In fact I assume he
takes out any call to the autorun in extROM which is why there are no app loads
when you hard boot his ROMs.
So you have a choice. Leave extROM alone and let 16MB of nonvolatile flash
rom sit there with O2 apps you'll probably never use again. Or, merge it into
the 16MB of storage space and get circa 32mb or storage.
There are always risks from flashing a pda device and messing about with flash
memory, especially from a non-official source. But then there are huge benefits from
c_shekhar providing us with a fantastic WM5 ROM that we otherwise wouldn't
have.
Hope this is correct and helpful.

Wrong thread to be asking in. But SD slot works ok on my XDA with 3.50a.40CS
I'd suggest you go back to an official ROM version and verify its not a hardware fault.

Good Sutdy and informations for the newbees. appriciations for sawyer_family. There exists the autorun program for installing the third party S/Ws and configurations at the time of hard reset developed by buzz. But, I have not provided it in the ROM. It can install the S/Ws and configurations from the resrve space into the RAM just like it used to be with the ExtROM. Here the advantage is that ExtROM can be placed on the Storage card. Like I am using it on my device to install the third party S/Ws and all the stuff at the time of hard reset. I have placed all these stuff in folder called "Storage Card/ExtROM". May be I provide it in my next release If people require. ......

Nice idea c_shekhar, it is a brillian idea to put extROM in storage card. It will safe much place in ROM. I will waiting your work mate !!!!

Thany you sawyer_family, you help me much to understand this topic.

ROMs

Can someone explain this to me. The storage in a device is in the ROM of the device. When you flash a cooked ROM it is in the ROM of the device. So are these in the same areas? When you look in /windows is that file what you flashed in or is it a copy? Where does all the space go?

generaly the full storarge is 128mb. the roms that are coocked are about 53-57mb unless the extended storage is included in the coocked version so it might be about 72mb (i think)
When you flash rom the computer loads the files into the phone, then the bar reaches 100% and a long wait before the phone reeboots. The rom files are locked for good; whatever aplications or upgrades you put into it do not overwrite any of the files in rom. so that when you hard reset only the original ROM files stay in the rom and all of the stuff you put into it are wiped clean.
The extended rom (correct me if Im wrong) is actualy located in the ram (usualy 10mb) This is the place where your carrier installes their programs and settings they desided are right for you. some developers also use the extended rom to put in their fixes.... However, all of that still gets installed into main device memory
Then there is a pagefile (from 4-8-12mb in some cases)
That leaves whatever miniscule remains for available storage and ram.
I hope that this is clear.

Can you just delete/add stuff to the extended rom or not?

Yep, absolutely agree with ya 100 % dude, ain't nothin to it.

[ROM][WWE] HTC Touch Official 6.1 ROM - ALMOST [Tabish ROM v3.3.6.1]

My Latest Official Flavour Rom
Tabish Rom v3.3.6.1 is here. The OS core is based on an extract and port from latest official HTC release (Opal ROM) which is closest to the HTC Touch sys folder. Base ROM remains 2.20.456.1B for OEM part which is the latest HTC rom for Elfs. This ensures 0 bugs, fast stable Rom which is VERY much what an official HTC Touch WM6.1 Rom would have looked like had they released one for us. Ofcourse mine would still have the advantage of being BIG STORAGE
Features/Updates from Tabish v2.x to v3.3.6.1 Rom
1. Wm6.1 (19971 Base from OPAL)
2. Esmertec JBed updated to 20080610.2.1
3. Default Pagepool to be Elf and Elfin friendly (though dsixda's EXCELLENT PP changer attached)
4. Task Manager updated to 2.1
5. HTC Random Access for contacts added.
Changes included from 3.3.6.1
6. .NETCF 3.5 (upgraded from 2.0) (Some people swear speed improvement, plus compatibility with new programs like Adavanced Config 3.x)
7. Bluetooth Activesync problem fixed
8. MSN connection fixed
9. Full Cities list (or atleast I think this is most complete list available)
I have also now included RUU files with download for people who are new to this.
PAGEPOOL and Memory
Rom is released with default 8mb PP setting but dsixda's excellent universal PP Changer is attached. I would like to give a disclaimer at this point that though the PP Changer works well with the ROM but I am NOT responsible for any damage caused by using the PP changer or my ROM for that matter.
Rom works very fast and very stable with 4mb PP with Elfs. Memory after first boot is as follows (for Elf with the default 8mb PP)
Storage
=======
Total: 47.94mb
In Use: 6.26mb
Free: 41.68mb
Program
=======
Total: 47.65mb
In Use: 25.44mb
Free: 22.21mb
But program memory quickly drops to
In Use: 28.39mb
Free: 19.26mb
after Cube is loaded in memory.
If you want more, you should shift to 4mb Pagepool but memory management for this build is very good and I have included the task manager screenshot below that shows 91% memory used while Audio manager, JBed, IE, SMS, connection manager and File explorer were open. For the record I was listening to a song, connected over wifi, downloading Opera Mini 4.1 on PIE and running Opera 4.1 on Jbed which was browsing facebook. I had the threaded SMS open and so was connection manager and file explorer (and ofcourse the screen capture program was in memory) AND cube was loaded n memory and I still had about 4mb free AND all this with the 8mb PP so you can imagine how it would be with 4mb PP.
Recommendations and Misc.
I strongly recommend installing the excellent IPL 2.27 and USPL 2.28 by htctouchp with this ROM. Its also recommended that you softboot and restart the phone once after first install before using it full time (works best after 1 normal restart)
Also I have attached a cab file for those who want to disable thread sms feature for whatever reasons.
Discussions, comments for this Rom starts on Page 10
http://forum.xda-developers.com/showthread.php?t=397739&page=10
DOWNLOAD & DONATION
Before you download and install the Rom think that if HTC offered an Official Wm6.1 upgrage for $5 for our HTC Elf/Elfins would you get it? What about $1? If yes, consider making a contribution for my work after you have tested and used the ROM because this is as close to an HTC Official Wm6.1 Rom as anyone could hope to get for our Elf/Elfins (and countless hours went into this)

Alright, FINALLY here is the download link

What kind of memory leak are you talking about? How long until you run out of memory?
When I reset it in bootloader mode it says SPL 1.11.0000 - Am I concerned with this possible leak?
I know that memory tends to diminish in time, but since I installed the auto-hibernate tool, it's better (even though it still runs down).

Zeflash if you have 1.11 SPL then you are probably using the 1.11.707 version rom which does not include the new keypad etc or one of the cooked roms.
Memory runs down on all Pocket PCs but with the new 2.20 series there was a leak where the memory would disappear for no reason till it got to low memory warning in matter of seconds specially after opening IE.
This ROM is intended for people who want the original ROM feeling, speed and stability with the new keypad included and want additional storage over the measly 25 mb offered by original Roms and are sick of the memory problems.
Regards

Ok.
Just a note, I believe it's quite anormal to provide a SPL in a cooked ROM. Usually it's only the system segment, sometimes the radio is included. Anyway. I'm fine with my SPL.

The older SPL is the actual fix for the 2.20 Roms and thats why its included with my original Rom and seperately for those who dont want to reflash the whole OS but want to get rid of the memory problem can just flash the SPL part that I have uploaded

For all those who try please give feedback

Would really appreciate if you could mention the details of available RAM and storage after using your ROM. I use an ELF.

I am currently using it with a 6mb Pagepool using the attached Activesync PP change (was originally at 8mb) and so currently I have
Storage:
Total: 49.18 mb
In Use: 5.12 mb (after installing a few programs. was more after immediate flash)
Free: 44.13mb
Program:
Total: 49.72 mb
In Use: 27.43 mb
Free: 22.29 mb
After leaving it on for DAYS it runs down to 19.81 mb but I can easily launch Audio manager playing mp3s over bluetooth stereo, Wifi connected running IE and Opera mini 4.1 in Cloudyfa's Esmertec JBed and still have a 1-2 megs ram free...

good work i get the same RAM config using the old 1.17.. ROM the touch Diamond keyboard. But will try your ROM have been long waiting for a good original ROM.

Thanks, very nice work, i am using ShadoW_2.1 WWE and after aplaying PP 4 mb Psgepool
I have:
Storage
Total: 57.18
In use: 25.18
Free: 32.00
Program
Total: 51.68
In use: 29.12
Free: 22.55
Working with SPB Mobile Shell V2.1.0.3363 with diamond skin, fast and smooth

I gess it suits for me.
One thing, can i flash fimmware to my htc if i have Mac OS X? Cuz i dont know how. Or in Server 2008 i simply dont have active stink.

pagepool change to 4mb. works fine to my elf. with 21mb free program for stable.
note: i have installed some games(4 games) with apps like opera, diamond keyboard, srs wow, mobile nero, htc stream & wisbar advance 3.

Cloudyfa is one of the most talented cooks EVER so of course his work is VERY good. This rom is more for people who like original roms. This is an original rom just with ext.rom removed for big storage and patched spl to fix memory leak experienced on Elf with the 2.20.xxx Elf/Elfin Roms

I prefer 6mb PP cuz I think it works faster than 4mb PP for things like touch scrolling through programs etc. And I like HTC keypad better than the diamond keyboard. But whatver you prefer, I am just glad you are using my ROM

Yeah original roms ROCK in terms of speed and stability. This SPL fix can also be used with the Australian Official HTC 2.20.710.2B ROM or any other 2.20.xxx Elf/Elfin ROM for that matter but if you get sick of running out of STORAGE memory as well, flash my full rom which is exactly like the original rom with just 1 difference that it will have 40+ mb free and if you miss the programs in ext.rom then ZIP is attached with ext.rom included cabs

Thank you so much. This is totally original ROM flavour with no add-ins. Tell me how it works out for you. For all those who dont like ROM's original midlet manager, I am attaching here Cloudyfa's excellent Esmertec JBed that seems to work without hitch on all platform roms I have tried

difference between cab install and cook?

sorry for a stupid question
any difference between that software cook in the rom and install by cab?
(eg. free ram)

maybe cooked in rom would be more stable than just install if treat well

cab is just the extension of install programs on ppc
cook is making an ISO of the operating system and flashing a rom replace the image of the operating system with whats included in the ISO

There is no difference regards RAM, there is an old wife's tale that it's faster cooked in but that's not the case as we use compression to which will actually slow down access very slightly.
The main advantage for me is being able to cook everything in so if i have a software issue i can just hard-reset and not have to install loads of .cab's of course this is only if the device has enough Storage to not have to worry about everything being in ROM.

got it!
Thanks for your reply

The difference is that if you format your entire phone, the software will still be installed on your phone. This way you don't have to manual install the programs 1 by 1.

Custom ROM for SM-J500FN

Hi
My first time here.
I've seen there is a forum specifically for this buy I'm not sure if my question should go there or here.
Samsung Galaxy J5 (2015) ROMs, Kernels, Recoveries
I have a Samsung J500FN with Android 6.0.1 and I'm looking for a custom ROM that can make it last a bit longer. Here are my requirements.
I don't want to root it as that will probably not allow me to use my banking app.
I need a ROM that does not have, or allows me to remove, all the bloat that comes from factory: word, excel, weather, powerpoint, chrome, facebook, samsung's internet, etc.
I've seen that some of the available ROMs come with Android 8, 9 and even 10 but I suspect these OSs take up a lot more space. If that is so I don't want them as my mobile only has 8 GB and I don't want to have to spend my days deleting cache, memory and apps.
Any suggestions?
Thanks in advance, Eduardo

chill bro,
1) for banking app like sbi uno and other use magisk. its open source and works well to hide root.
2) android 7 would be great for you because samsung switched to art in it and is a lot faster smooth and consume less space and is supported by most apps.
3) i know the pain of having 8gb rom so, try to use opera mini instated of chrome and try to optimise system by removing unnecessary software using root+magisk.
4) android 9 is also good. just flash try and see if its what you need.
thanks hit like if i helped.

3) i know the pain of having 8gb rom so, try to use opera mini instated of chrome and try to optimise system by removing unnecessary software using root+magisk.
4) android 9 is also good. just flash try and see if its what you need.
thanks hit like if i helped.

I would like to try Android 7 if it's lighter then Android 6 but I prefer not to have root.
I've been reading that ING app doesn't work with magisk so I prefer not to struggle there.
Why doesn't my phone automatically update to Android 7, doesn't Samsung provide for this?
Where can I download a Android 7 ROM ?

IMHO LineageOS is the right choice for you.

Do you think that even if it's Android 10 it will be lighter than my present Android 6?
As I mentioned I don't want to root. I see that the link you included has a GAPPs installation so I guess the Lineage ROM comes without those.
I use OpenSuse linux so I would like to install from there, any problems?
Otherwise can I do it from a Windows 7 virtual machine?

It really doesn't matter whether it's Android 10 or Android 6 or whatever version what is running. As with any Android for each app a predefined heap size ( the maximum amount of RAM the app can allocate ) exists which is passed through configuration properties inside Android's build.prop file. Usually, heap size is relative to the RAM size of the Android device. So, an Android device with 1 GB of RAM will normally have a heap size of 128 MB and a device with 2+ GB RAM a heap size of 256 MB.
Assuming Android OS itself is eating 500 MB RAM to properly run, then on your phone can - at maximum - run up to 30 apps using 256 MB ( large-heap-size ) simultaneously.

Thanks for your reply.
What I meant by lighter refers to the scarce 8 Gb on my device, not the RAM. With only 8 Gb there is a very low limit to the amount of apps I can install. Maybe with Lineage there is more of those 8 Gb free.
And that takes me to the Gapps packages. When reading the link for Gapps it offers various packages and I'm a bit lost as to which I should download.
Open Gapps for LineageOS 17.1 GSI build: Download
Open Gapps for Android 10
ARM: Download Open Gapps 10 ARM Zip
ARM64: Download Open Gapps 10 ARM64 Zip

GApps for LineageOS 17 | Link

I've downloaded the Lineage ROM file and have a doubt about the name of the file and whether it's valid for my model. The name of the file is
lineage-17.1-20201213-UNOFFICIAL-js01lte.zip
What worries me is the "...js01lte" part.
My mobile is SM-J500FN, also "j5nlte"

ok, I think I'm almost ready to flash my first ever custom rom.
I've been reading to understand what I'm getting into.
One doubt. It seems that TWRP is capable of installing the custom rom without me telling it what partition it should be flashed to.
My question, if I want to flash a Samsung stock ROM can I also use TWRP or must I use Odin or Heimdall and flash it to the appropriate partition?
BR, Eduardo

Before I proceed
Installation instructions state "Then, select the System, Vendor, Data, and the Cache partition and perform a right swipe to format the selected partitions."
My device doesn't show the vendor partition.
Is it ok to proceed ?

Still insstalling? I think lineageOS is not the right solution for you. I got the same phone and made it work by disabling bloatware.

Hi Kurtin
from what I've learnt until now disabling bloatware doesn't free up any space, it just doesn't show but it's still there.

You need to see the partitions separately. The stock version of each app is stored in system partition. That is no problem. You can't use free space in system partition.
Our problem is data partition. Each enabled app will try to store it's data and updates in data partition. That makes the device unusable.

I think I understand what you mean and therefore installing a different ROM won't help unless it changes the partition setup.
Thanks for your support.

Installing a different ROM will help. Custom ROMs usually have less bloatware that occupies data partition for updates.
Same effect as disabling apps in stock ROM.

Hi
our exchange started when you stated "I think lineageOS is not the right solution for you. I got the same phone and made it work by disabling bloatware."
Can you propose a better custom ROM that addresses our needs or didn't you explore that track?

LineageOS 17.1 should be OK.
