Warning: This flash will overwrite your extended_rom!
This rom is very similar to my Dopod Lite (now D-Lite!, I just thought of it!) rom, however, this one is based on bepe's modified T-Mobile 3.6 rom, so it converts your extended_rom memory into additional storage memory. Until I can figure out exactly what bepe did and apply it to the D-Lite rom, I thought I'd put this out there for all you storage memory freaks. (You know who you are.) This is pretty much equivalent to my DopodLite V1.0, so you can read that thread for info about what it looks like, and what I've done to create it. I hope it proves to be just as stable.
Like the Dopod version, this is meant to be a stable, fast starting point for your own creativity. It's much easier to mix and match applications after flashing than before. If you get tired of a particular app, just remove it and try another. If you get tired of a particular skin, try a new look. There's plenty of stable, fast storage memory for loading your today screen utilities, phone apps, voice dialers, animated screens, etc, etc.
This rom does not have: Transcriber, voice dialer, catalog, error reporting, autoupdate, phone home (ceipui), games, calculator, some audio files and other odds and ends. It does include: Office 2007 (No OneNote. Thats not particularly useful unless you have it on your desktop, in which case it installs automatically anyway.), Java, .Net, all the Bluetooth and security stuff, MMS, Camera, and the rest of the basic functionality. If you want transcriber or a voice dialer or games feel free to add them. Ditto for the calculator, which needs replacing anyway.
At cold boot:
4mb page pool: 71.47 mb total storage, 67.10 mb free storage memory, 31.19 mb free program memory. If you delete the startup folder shortcuts, the program memory goes to 31.97 mb.
6mb page pool: 67.10 mb free storage, and program memory is 29.08, and 29.87 mb respectively.

Hi Edward,
Got me nervous (I hadn't checked it), but I'm connected with my home network now. You may have to look up the registry setting to activate "G" capability if your home network is set up for "only G". (Or use a tweak utility that does it for you.) I'm running "G", with a linksys router with WAP, AES security. Works well.
Good luck!

To provide my feedback after a couple of hours using....
No problems encountered so far, 3G or WIFI working
Edhaas, as I am really crazy for more RAM, just a suggestion:
Removing application that is rarely used i.e. internet sharing, midlet manager, SAPsettings, streaming media, customer feedback, error reporting and some of the ringtones i.e under the windows\rings folder.
A noob question, noted that from Settings>About>version, the memory in is only 51.02 MB while the total/free storage memory is more than this. Is there any 'truth' in the version memory or just a display?

Happy to help. Glad you're liking the rom. I'm not finding much different in feel from the D-Lite rom (which is a good thing). Everything is working well for me as well. HSPDA, a2dp, wireless stereo over wireless radio in sleep mode sounds great. No lockups so far. All my apps work as before.
Tutorial regarding memory: In this rom there are two types of built in memory, storage memory and program memory. They are physically different and cannot be interchanged via programming. In other roms, the storage memory is broken up and part if it is used as "extended_rom" which is meant to be hidden and used by carriers to put their particular customizations in, which are generally only used once after a hard-reset. This partition was about 10mb in size. Bepe has figured out a modification, which removes this partition and makes the user storage partition (where programs are stored, similar to a disk drive) correspondingly larger. Another partition is used to store the base programs which are "flashed" and include the operating system. Tadzio figured out how to move the boundary of this partition so that smaller roms will free up more storage memory as well.
So, end of history lesson. The storage memory is what is left after all of this, and is used as a "disk drive" equivalent, it is slower than the "program memory" which is like "ram" in your computer. However, storage memory is generally faster than SD card memory, and is preferred especially for "resident" or today screen type programs, because it's instantly available when you first turn on the device. Most of what I and others have done is to maximize the amount of this memory which is available to you, so you can fill it up with programs that load more quickly than if you put them in SD memory. In this rom that free space starts off at 71.47 mb, and then at start-up the operating system allocates some for it's own use, and in other roms customization programs loaded after cold reboot are loaded in there. So, in this rom there are actually 67mb available for the user to play with, which is a ton, and pretty much overkill for 99% of people including myself. As long as there are around 10mb free for the system, the device will work well.
Program memory is "ram". It is the fastest memory and programs in actual use are executed from there in chunks loaded from storage or SD card memory. It starts as 64mb, but the device uses a good chunk of it internally which we have no control over, and so reports the 51.02 mb as what is initially available. However, an additional chunk is used by the operating system, of around 15 mb, leaving the rest for us to actually use. The page pool, which is a buffer used between ram and storage memory comes out of this, as does the ram used by any start-up programs. Generally, as long as you have about 5 mb or so available, the device works pretty well.
[Edit: Addendum: In this rom I have removed error reporting and customer feedback, I'm having more difficulty removing the icons for them however. The other things you mention could be removed, but this would reduce functionality for folks who use those things, and would only add slightly to available storage memory, which as I stated above is already in the "overkill" category. I'll probably cut some more stuff in later versions as I gain experience with this rom, but I doubt there will be any noticeable difference in performance or usability.]
This is a bare-bones account, but hopefully will help you conceptualize things.
Best wishes, and enjoy!
Enjoy the silence!
Added addendum to above. Also I want to report over 50 downloads in less than 24 hours, and no real problems reported. Sounds like another quietly effective launch!
Enjoy your weekend!

ROM hangs and then Hard Resets
Hi Edhaas,
I'm facing issues of Hard Resets.
This is already happenning twice in a day.
I do not have this issue using your last v1.2 versions.

The device hangs randomly.... and once u do a softreset....
It then turns out it hard resets itself.
I'm not sure if its due to MortPlayer?
Anyone have this issue?
Regards
Never experience the problem u encountered... never install MortPlayer
Try running the rom without MortPlayer, c what happen!
rgds
@fychan, I run mortplayer and was going to flash this rom tonight.
What version of mortplayer are you running?
I am currently running 3.31b61 on edhaas's d-lite without issue.
However, on past roms (black 2.5 thru satin and sleuth's developer 2 and 3) I discovered that 3.31RC7 was more stable.
Perhaps downgrading might solve your issue.
fychan,
I can't seem to replicate your issue.
Are you running anything else that might be leading to your strange problem? I ran the latest mortplayer build, playing for a while, pausing, turning off and on, resetting... At no time did my machine reset itself.
BTW, from the little I did see, it looks like a fast little rom here. I can't keep it though as it has the sms/mms together.
Hi all,
I have been suffering by this issue.
I do not have many program in my x01ht, only isilo, mbook, rescoviewer, rescoexplorer, PMcontact, pocket imformant HTC Home, Slide to unlock 0.72, CE-Star, CORG (some of them are installed in card memory)
Everytime after I soft reset my x01ht (offical WWE ROM), I have 26-27M program free
However, after running couple of apps., the program memory drops (of course), the problem is if the app. takes 5M of program, WM6 only release 2-3M memory after I close this app.
So, after half day using my x01ht , I must reset it once , otherwise there is less than 10 M program memory free inside, and I could not run more than 1 program or use PIE to surf internet
Does anyone know anything I could do to fix it ?
Or it just normal because it's based on "window" ?
Appreciated!
I use a small app called "Hibernate" to release closed program memory daily. It was installed already on my TNT rom, so do a search should to find it's cab.
Freeware Oxios Memory (containing Hibernate and Close Apps mentioned in above post) can be downloaded here.
Thanks so much Guys, but I also read from this forum, somebody said this program makes hermes device no more multi-task functions
Everytime users only can run one program...very weird.
Any other users tried this program on Hermes? (Offical WM6 ROM or Cooked ROM?)
Actually I am trying it now, but I have a question, what's the difference in function between Osios Hibernate and Oxios CloseApps ?
Thanks
Not even Oxios Hibernate can free all used RAM. It's an OS issue, called memory leak.
Hibernate - free RAM without closing apps.
CloseApps - Hibernate + Close all apps

Thanks so much,
I have found out something weird after I install this app.
It automatically closes my app. after couple of mins (after use) , even I only run ONE app.
And it closes app. when I run more than 3-4 apps at the same times immediately (after I run the 5th or 6th app. )
I thought Hibernate and closeapps functions when I click it , but not automatically close my apps., isn't it?

They should work on demand - i.e. only when you run them by clicking the icon/exe. I am using these two apps for quite some time and never had such an experience you describe. Seems the culprit is something else in your case...
It's a natural WM behavior to close other apps when the system requires more memory. For example, you open up calendar, then you open up a game that requires a lot of memory, WM will close calendar automatically.
It's not the Hibernate/CloseApp app that's doing it.

But before I installed this oxios memory, It didn't happen to me.
And after I uninstalled it, It doesn't happan again (I uninstalled it over 1 day)
So , it sounds a bit weird for me......I really have no idea.
But anyway, thanks so much guys!

Answer to your first question: I do it even more often...
I prefer Hibernate.
You are right Closeapps closes the running programs and has hibernate function included. If these apps do not work correctly for you you can use commercial or freeware version of SkTools (it also cleans RAM apart from tons of other functions or also commercial MemMaid - that will let you clean tweak everything connected with memory in your PDA.
Oxios CloseApps doesn't close apps. I don't know if it's because it doesn't work with WM6.1 but when I use it all my apps are still running. Have to use QuickMenu's "close all apps" mode.
Hi.
I'm still using Ausdins 6.1 Rom, but would like to jump on the Manilla waggon. I'm a bit worried about the RAM consumption.
Could you please report your free RAM with the different ROM's you are using. (Program as well as Storage).
RAM usage
I would say you must allow 5-6M for Manila proper operation with AS on, push mail, SMS, etc.
Since our trinity is only 64M it is crucial to ask yourseld the following questions:
1. Can you allow a bit slower performance and get more free RAM? If yes, play with pagepool and use a good solid cooked ROM. 4M pagepool gives about 50-51M of free RAM. With Manila on you still have 18-20M free RAM. Unless you try to run memory hungry app like igo, it's plenty.
2. Do you mind shutting Manila off and on from time to time? If not, then keep in mind Manilla is just a desktop plugin. Turn it off and you get the 5M back...
I do so often before I run igo. m Today, or Manila on/off app is doing it with one push of a button within 5 seconds.
Generally speaking, trying 6-7 different ROMS, choose a manila cooked ROM. Look for the lite ones that do not come with Google maps, player, you tube, and photo album in the ROM. Those are light and fast. You can always add the rest as separate cabs. All is found on this forum on the general areas. Storage vary between cookers depending on ehat the ROM has, and if they put full blown M2D or not. Never had a problem with it, and have seen any number from 12M free ROM to 50M... depending what you get in the cook, so it's hard to tell...
Enjoy. M2D is the best dsektop plug in I have ever used, including SPB shell. But it is only my opinion...
Thanks for your advise. I think I will try.
1. I don't mind having to shut down manilla in order to run ie TomTom. As I don't need push mail, maybe that will save som RAM as well.
2. Is it all Manilla ROM which allow to quickly close it, or should I look for a special program (addition in tha ROM) in order to have this function.
how to switch Manila on/off
Well, some ways of doing it.
1. Old fashion - setting->today
2. Using M2D DevTool
3. Using mToday
The last two are free on this forum. BTW - ROM and RAM are two separate entities. I was referring to RAM , not to the storage for programs, that was never an issue, especially with SD cards. 64MB RAM is the main reason I am looking into replacing the trinity, as for anything else, there is no significant difference with the newer HTC versions.
Guys, i'm going mad.
Since i have iPhoneToday installed (with many icons, i admit), my GWES.exe (WM 6.5, ROM NextOS 1.2)raises quickly to 20Mb memory usage. And then, as soon as it reaches 20 megs, HTC MEnu Enhancement stops working leaving me with an unusable system (breaking HTC Menu results in apps not showing at all their menus). CleanRam usually takes it back to 13mb, but i have to run CleanRam about every time i run an app (and that's bad).
For what i know, processes should have a 32mb space, so my questions:
- why the hell my GWES kills HTC Menu at 20mb?
- is there a way to give GWES more memory to operate? (i've tried to reduce the payload uninstalling topbar and gaining 3 mb, but it's not enough).
- i've seen there was an old patched GWES floating around for and old problem of HTC enlarged menus working bad: is there something similar for newer GWES's?
-as alternative: is there a way to flush GWES when it reaches, to say, 19mb, so that it doesn't reach 20mb limit and breaks HTC menu?
Thanks
I found this topic via the search button because I have the same problem with Dutty Leo R5.
When softresetting the phone the application gwes.exe (Graphical Windowing and Event System) takes about 15-16MB, thats absolutely OK.
Now after some time using lockscreen and some other apps the application gwes.exe grows up to 27MB. These 27MB seem to be a magic number, because when gwes.exe reaches 27MB the menus are getting very ugly. (ill try to find a screenshot to explain what I mean)
Somehow for you its 20MB, for me it was ~27MN.
After some more time gwes.exe takes more than 30MB and then it happens! Alot menus arent beeing displayed at all! Also some other applications dont start at all or better dont display a single picture or text...
No1 an idea what we can do with this gwes.exe thingy?
Since there were no answers, I have solved this problem myself long time ago.
You can use the attached cab: it will install another GWES.exe and GWES.exe.0410.mui version, that uses much less memory (at startup now i have 12 mb WITH 5 megs of iPhoneToday icons, it means 7-8 megs if you don't use it).
Of course, if you haven't italian ROM, remember to rename the GWES.exe.0410.mui accordingly to your ROM
BEWARE! Installing a wrong GWES version could lead you to hard reset!!!
So, install at your risk. This is only for WM 6.5!!!

It depends on how you read it: i use sktools, that reads different, for example, from memmaid, since it splits size and heap

if you cannot install it in any way, the only solution is to copy the files manually (attached for your convenience):
1- with resco explorer or total commander go to \windows and rename gwes.exe to gwes.exe.bak and gwes.exe.0410.mui (or 409, or whatever is your country code) to gwes.exe.0410.mui.bak
1a- if you cannot rename, this means the files are in ROM, so no problem: go to 2
2- copy the new files to SD, and then again with resco or total, move (not copy: move) the new gews.exe and gwes.exe.0410.mui to \windows. (You'll be told "warning the files are in rom you can damage and blah blah": answer you want to overwrite).
3- import the .reg
4- soft reset
I was able to copy to device but my gwes.exe still shoots up to 25-27mb after locking the phone. I'm curious though after importing reg file it did not notify if it was successful. It just asked me if I wanted to import.

This is the normal behaviour. btw, the reg only disables magnifier (since this is a newer gwes with magnifier embedded).
may I know the origin of the gwes.exe file? which build was it taken from?
I am using 21869 build now and the gwes.exe still keep "expanding" after long usage of Garmin, Opera, etc, but the HTC Menu stays working even gwes.exe has expanded over 30MB.
By the way, I have also tried smaller Font cache size, fom 32k down to 8k and it does help to reduce gwes.exe size.

Hi all
Has anybody tried bbonzz Anti-GWES leak-EN.cab on MS build 21854? If so, can you please post your results. I'd like to get gwes.exe down in size but I don't want to have to hard reset my device.

I've came to this thread because I've the same problem and I've found that when GWES is near to the Windows CE process limit of 32MB some graphical intensive apps stop working.
I read the memory usage with memmaid, so it gives a mix of size and heap.
If an app creates a new DC and its asigned memory mapped bitmap for some graphics and does not release it, or create any kind of graphical objects and does not release them, it results in GWES memory leaks, and as soon as it reaches a memory usage near 32MB, if another app tres to create graphical objects, receive an error and cannot do it.
I've started my HD Leo Holy Gray R0 and GWES takes 15MB of RAM, but in my Diamond WM6.1 without Manila it take only 1.7 MB of RAM.
So there are three problems: Initial usage, badly written programs and new graphical intensive applications.
I'm the programmer of a graphical intensive commercial application. When some menu is opened, I need almost 3MB of GWES ram that I liberate as soon as the menu is closed. I've tried starting the app and the menu 50 times and closing it again and GWES have not increased its memory usage, so it can be done.
My advise: Try to identify the app that is leaking memory in your system and avoid it. Look for a replacement program that is well written.
Do I have found a solution?
I use a lot Resco explorer, that has a new look since WM6.5: the treeview control for folders is now more "expanded" and have bigger + and - simbols.
I don't like them so big, so investigating I've changed these two keys:
HKLM/System/GWE/CommCtrl/TreeViewPlusMinus to 18 (0x12)
HKLM/System/GWE/CommCtrl/ExtraItemSpace to 4
And not only it now shows the treeviews like before, but I've not got any problems with GWES since I did it.
Maybe there has been introduced memory leak on the treeview control functions when them have been modified to support this new style?
Good contribution, lets test it and report!
gwes.exe heap size is huge
I tried the tip above and my gwes.exe heap size did reduce by a couple of MB but at one point yesterday the process details (from SKTOOLS) for gwes.exe was over 100MB.
My phone's an HTC Touch Diamond 2 but wanted to include it for reference.
Name---- ---Size ----Heap Path----------------
gwes.exe 4247552 85132896 \Windows\gwes.exe
Would the tip above about replacing the gwes.exe be compatible with my phone too?

Hi all, after install WM6.5, it seem the RAM is always on high consumption. even I cancel the running program, the ram still not back to lower ratio. I have tried install some FreeRam program for WM6.1 but it seems doesn't work on WM6.5, anyone have new freeRAM program for WM6.5?
HTCAddicts.com's CleanRAM works fine in WM 6.5 (www.htcaddicts.com)
Hi,
Unfortunatly it does not work as the only thing it is doing is closing and restarting apps.
You can do this manually with pretty same results.
But the problem of WM6.5 or HTC Sense or whatever I don't know is Memory Leak concerning GUI handling. Take a look a gwes.exe memory consumption at start and then at the end of a regular use day with all apps closed. GWES.EXE will take twice memory than it took when you soft resetted.
And I think nobody has find a way yet to get rid of this problem.

Thomas

oh, I did mean to use cleanRAM manually (actually, mode 3) ... guess you're technically right, tho
Thanks! I think use this better than nothing. About the final solution, it may need to wait the HTC update ROM to settle this problem.... so sad!!
try to make the shared memory smaller
this problem is caused by the shared memory.
HKLM/ Software /HTC / Resloader
look for that registry setting and recalculate it to half. that might solve your ram issues. I had to do it with my Kaiser running M2D. Fixed my problem when I set it to 3mb (1024 x 3 = 3mb.) You need to make sure that the math is correct so that you are not wasting any sectors. 1mb increments works well.
I would reserve at least 10mb for TF3D as opposed to the 3mb for M2D.
Use this at your own risk and make sure you backup first, in case you will have to do a hard reset.
also, in order to see actual memory usage for processes you should use the MS task manager, not the DF TaskManager. MS gives you accurate readings, while DF lets you close processes.
I just tried setting it to zero. no harmfull efects.
thanks for your advise, I don't know how to caclulate this but task manager could help. may I ask when can I found the task manager?
