Have you use the Windows Mobile Device Center?

Maybe you can try flashing [upgrading] using mini-SD card refers to How to upgrade using SD Card on Wiki

But you have to use the 512 MB mini-SD Card, coz I've tried to use 1 and 2 GB and it all failed.

Only 512 MB that succeeded

!!!

And I've used the Free Hex Editor Neo to cut the header of "diskimage.nb0" and saved it as "diskimg.nb0".

Then I copied it to my mini-SD 512 MB, followed the instruction on the Wiki above.

And it worked...I can upgrade via mini-SD Card. :cool:

Good Luck.
[iPAQ rw6828, XDA Atom ROM Development] ekym44:
ekache,

i thought, upgrading from sd card is only for semi bricked atom exec?

i don't know that it can be done...

thanks for sharing.....:)
[iPAQ rw6828, XDA Atom ROM Development] ekache:
Infact, I already done it (Upgrading via mini-SD card) with TJ's ROM : 20931, 21014, 21202, 21210, 21501, and 21231 instead using the DSUU upgrading.

In addition, I renamed the "ExtendedRom.img" to "extended.img" coz it was needed to got the perfect flashing.

So the "diskimg.nb0" has an accompany named "extended.img", then I put both of those files to the mini-SD (512MB), so the upgrading process will run perfectly.

I was just curious if it can be done with my HP RW6828, why my ATOM EXEC couldn't ?

I tried it and I did it. :cool:

Well I don't have to worry again if the DSUU process fail in the middle of flashing in my PC/laptop,

I just cut the header of "diskimage.nb0", copy it to mini-SD, plug the power...let it flash with no PC/Laptop needed.

Done. :D

It can be done for all of TJ's ROMs, as long as you cut the right header refers to Wiki. :cool:
[iPAQ rw6828, XDA Atom ROM Development] ekym44:
only those two files are enough, i have also a winhex editor, and it is okay...

but i never try to upgrade using sd card, i was a little bit afraid of having my bhebheko(this is what i call my atom exec :D ), bricked... :)

First I would like to say thank you to you guy for your ROM. :D

[iPAQ rw6828, XDA Atom ROM Development] onnicked:
Thanks for the ROM TJ

I've been using the wm6.5 rom by TJ... works great... (Atom Exec)

but the thing is when receiving MMS... cannot be open or view.. i dont know what problem causes it..

another thing is, HTCcalculator, HTC Album (HTC programs - Front list) is not working...

Some menu cannot be read, maybe because of the language.

thats what i found out for now.

hope you can review it back TJ...

thank you...
[iPAQ rw6828, XDA Atom ROM Development] xda2_haseeb:
Can i know how much free RAM do you guys have at Boot after a soft reset?? sorry for this stupid question but i dont own a Atom and was thinking of buying a O2 XDA Atom Exec, do u guys thinks its a good choice?? THNX.
[iPAQ rw6828, XDA Atom ROM Development] tjkhattak61:
Page Pool Changer (included in the WM 6.5 Kitchen gonna upload shortly)

MMS problem is being checked now

On WM 6.5 it is 22.30 MB on soft reset and sets somewhere between 13-15 MB after a day or two.

Atom Exec is the best only draw back is battery life.

THNX :D so ur from PK?

Do you know would TouchFlo2D work on Atom Exec??
[iPAQ rw6828, XDA Atom ROM Development] tjkhattak61:
Yep the Great Pakistan and yes TouchFlo2D works for Atom Exec, I have just released the 21051 version for Atom Exec with built in Manilla 2D in black (though credit for Manilla goes to my friend Jaime).
[iPAQ rw6828, XDA Atom ROM Development] xda2_haseeb:
well... thats where your mistaken my friend :) in talking about TouchFlo2D not Manila 2D. I dont knw the differences but they are different alright and TF2D cant be ran on HTC Wizard due to the heavy graphics ;)

EDIT: well maybe im taking the wrong name it might not be TF2D but something else :confused: it was a thread in Developement section ill search for it again, well im not hoping to find it again :p
[iPAQ rw6828, XDA Atom ROM Development] tjkhattak61:
TouchFlo 2D is a concept introduced by HTC and now in newer sets like Diamond 2 it is TouchFlo 3D.

TouchFlo 2D was introduced as Manila 2D for other devices or non HTC devices by an XDA member here http://xdaforums.com/showthread.php?p=2277665#post2277665 and u can go through this http://xdaforums.com/showthread.php?t=430916 and http://xdaforums.com/showthread.php?t=451727 .

TouchFlo 2D is running very fast on Atom Exec because of its 520 MHz processor :cool:.
[iPAQ rw6828, XDA Atom ROM Development] xda2_haseeb:
well i culdnt find the link... and i knw all about the M2D :D i also have it in my ROMs :D the thing is wht i was talking about was a step down version of TF3D which culd run on smaller devices :) unfortunately not on HTC Wizard well leave it ;) can u tell me whts the standby time of XDA Atom Exec??
[iPAQ rw6828, XDA Atom ROM Development] tjkhattak61:
Yeh TF3D is a problem. Atom Exec Battery (i Have an old 2 years) in standby runs for more then 24 hours.
[iPAQ rw6828, XDA Atom ROM Development] xda2_haseeb:
okies :D i guess more thn 24 hrs be enough for me coz im texting arnd 18hrs a day :p so it must last 24hrs and i can put it on charging in the nyt :D

And my bad, I am sorry there is no Quick Menu and no Office/note. I have corrected the first post SORRY.

People u wanted a clean clean ROM so it is here :confused:.

I will correct the calculator problem in next update.

I am sorry I cannot be very active due to my job, so u have to wait, even my friend Jaime has to wait for the Kitchen to cook a beauty of his Blue MD2 (Hey Jaime it is coming man but I want to correct it as much as possible).

OK guys I have corrected the SMS folders "Sent" and "deleted" not visible, now they are visible.

Corrected the bluetooth hands free not working problem. I have a Jabra BT 800 and it is now working fine. U complained about files transfer not being done through bluetooth but I have no such problem. My brother u have to switch "Receive all incoming beams" even for bluetooth to transfer files, so check it in the connections folder and u can transfer files through bluetooth.

The internet sharing is also corrected and included in next update.

No news of A2DP yet sorry :(.

Hope u can wait for 1 or 2 days for the next update which fixes most of the problems.
