After I successfully backup my O2 Mini existing ROM to the SD Card by the romupdate.exe. I used the ntrw.exe to convert the Image in the SD card to my computer. However, when i excute the command
> ntrw read backup.nb1 X:/
it return the followings..
>could not open backup.nb1 -- the volume does not contain a recognized file system. Pleas make sure that all requited file system drivers are loaded and that the colume is not corrupted.
I have tried other card reader (both 1.1 and 2.0) other computer and other SD card ( i am using LEXAR and Kingston 256 ) but the problem exists.
and the romupdate said the d2s command was success.
Why will it happen and
What can i do to fix this problem????

You need to use a card reader and the drive X: should be the drive XP allocates to the SD card slot on your reader.
XP Assigns my SD reader to I: unless you have a lot of network drives on your PC it should be somewhere. The card needs to be in the card reader slot obviously and not the PDA.
I am also assuming that you are trying to write the Rom to your hard drive and not writing it back to the SD?

Hi there, looking at the dos screen you took, its telling you that you have already a file with that name in the folder. look, delete that file... and then try again... i had that problem yesterday. Now im struggling to upload the rom.

by wrong command also, it creates the nb1 file. so do DIR and see that .nb1 with 0 bytes will be there. delete it and try again!

SD Card problems after using Romupdate and ntrw

SD Card problems after upgrading to 1.12
I posted this in the normal form but no one replied, I think this may be a problem causing my upgrading, so I post again here
--------------------------------------------------------------------------------
The SD Card used for dumping rom with ntrw could no longer be accessed by my notebook which was accessable before(I formatted the SDs already with my mini), it needed to be formatted, after I did that, and plug the SD into my mini, the mini couldnt read it and prompting the SD card needed to be formatted again!
So, I formatted it again with my mini, but after that my Notebook want to format the SD again, and the fight between them keeps going...
anyone encounter the same issue...there are some clues that I tested:
1. I got 3 SD cards, 2 for them used for upgrading and they occured the same problem, but the third one which is clean can be accessed by both machine
2. The SD cards(those with the problem) can be read by my PC's Card reader...
I know I could use the card reader instead, but I dont wana waste the build in one in my notebook and the data exchange between my Notebook and mini is quite important to me, pls if anyone could help me solving the problem, Many thx!

Hi, you must use ntrw in comand window ( in winxp run cmd )
Take ntrw.exe and your file.nb1 in roof directory.
Type the command C:\ntrw read rom.nb1 x: ("x" is your cardreader name)
Ignore any error message when you plug SD card into your cardreader.
After that you type d2s in next window, so on...
When finish you will have file .nb1 in your roof directory.
Hope you successful !

Sd card problem on Magician

Hi Bro,
I need some advice on O2 mini as my SD card is not working good.
Before I started my Rom experiment, the SD was working good with both the magician and my laptop.
I made a mistake and I did not backup my rom before I start flashing.
After changing to my new rom, seems like I cant inter-use the SD between my laptop and magician. The magician cant read anything from the SD if I put data into the SD from my laptop via SD card reader/writer. When inserted to the magician, it will prompt to reformat. The same thing happen when I slot in the card to card reader after writing something from magician.
Therefore, now, I cant use SD to update rom ect.
How can i solve this problem? Thanks
Russ

Have you already tried formatting the SD card? When an SD card is used for ROM upgrading the card becomes totally unreadable for both PC and Magician.

Zerimar,
I did reformat of the SD on my laptop before writing the image to the SD via ntrw.
However, after slotting back to Magician, then go to Bootloader mode and wait for the "start loading prompt" but that have not happen yet.
russ

I think I misunderstood you, sorry. Put the Magician into bootloader mode first then insert the SD card. It should then display the message asking you to press the Power Switch to start the upload.

Thanks for your reply dude,
I've tried that too. It does not look promising.
I hope there is nothing wrong with my sd slot in the magician and i dun think there is any hardware problem. I confirmed that the Image was written in the SD.
Initially the SD card was working well with the magician before i did any rom flashing myself. even with the 1.12 WWE rom i cant read the SD. I've tried to reformat using XP on my laptop, and put back to magician. Then the magician will prompt to format again. else i cant see the storage card in the file explorer.
I've tried:
1) Slot in SD and wait - DUN WORK
2)Slot in SD, disable Async USB, and slot in use to Magician and wait. -DUN WORL ALSO
3)Slot in SD, press camera, on/of, and reset and wait till the SD load screen- ALSO DUN WORK.
4)Go to Boot loader, the slot in SD and wait- ALSO DUN WORK
5) No more idea
I wonder if different rom version will not work with certain sd brand.
My details is : 1.12 WWE with big storage.
SD : Kingston 256MB
I've tried with 1.13 WWE also but the same problem.
Hope someone can help or anyone have the same problem before?

Hello, Try this one
I think if you get problem with the SD card, you can use Mr. OLTP ways.
First open this :
http://wiki.xda-developers.com/index.php?pagename=MagicianRomUpgrade
then
downloadls all the tools you need, from the site.
1. Unzip NL_11300_131_11200.exe (or any other shipped-rom) to get all the .nbf & enterbl.exe . click right your mouse and chose extract to NL_11300_131_11200\
then you must copy all the file from NL_11300_131_11200 folder to c:
ex: c:\temp (make a new folder "temp", and copy the file from the NL_11300_131_11200 folder).
2. Put NBFDEC in the same directory = open nbfdec folder, you will find release folder in there, open the relase folder and copy 2 file to c:\temp.
3. open the temp folder and find getdevicedata.exe, Copy the getdevicedata.exe to your Magician and execute it (it will not provide any gui displays or feedback whatsoever), open the windows in my device(in your PDA), search for getdevicedata.txt. then copy to your desktop, and open with notepad.
4. To decode nk.nbf -> nk.nb1 start a command window, go to the directory where you stored nbfdec & the other files & type: nbfdec -d nk.nbf nk.nb1
this isi the ex:
in cmd
c:\documents and settings\frans>cd c:
c:\documents and settings\frans
c:\documents and settings\frans>cd ..
c:\documents and settings>cd ..
c:\>cd c:temp
c:\temp>nbfdec -d nk.nbf nk.nb1
this will convert nk.nbf to nk.nb1
don't close the CMD windows
now open the Hexeditor (must use the newest version V3.x)
open file/nk.nb1
then klik replace button , in the upper insert 02 00 00 80 00 20
in the lower 02 00 00 b8 01 20
replace all, enter.
save file in same name.
then back to the CMD window
c:\temp>nbfdec -e nk.nb1 nk.nbf
and
close the CMD windows.
open the temp folder, plug your PDA to USB,
On your PDA press power,camera and reset to bootloader mode.
clik maupgradeut_noid.exe on the temp folder.
and follow the instruction. if shows error 120. repeat again clik maupgradeut_noid.exe this will start to instal your OS
FINISH
thanks to MR. AMPDA, MR. OLTP and Mr. SEAN
for helping me.

Pls follow the guides on the board a little more carefully! Mine is very good ;-)
When you dumped your rom image on your SD with your magician, you completely destroyed the MBR of the SD. Before you save the image to your laptop with ntrw, your laptop will want to format it, cause it can't unserstand the car
. Don't do that. just put it in your cardreader & back it up with ntrw. Then you can write back another image to the card with ntrw & put your card in your magician. Just as long as you didn't format the card in between the operations the bootloader will recognize the image on the SD by the word magician which must be the first thing it reads on the card. If there's a mbr instead of the word magician, no mather what the bootloader will not present you the image 'press power to flash'
Hope you understand know how to solve your 'problem'

Hello yeoruss,
did u actually fixed the problem with using the sdcard on notebook and ppc at the same time? Ive the same problem after storing my ROM on SD.
I simply cant use the card in both units. When i format it under windows, is works in Windows but not on PPC - The PPC asks to reformat the card to make it readable.
When I format the Card on PPC, it works there, but no more in Windows.
Im experimenting all the time but i cant see the solution
Edit: I did not changed the ROM on my Magician, i just tryd to backup my current ROM.
Thank u

o2 mini flash to big storage ROM failed.lols lols.

i followed every step in "ampda_how_to_upgrade"
till the last part.
-------------------------
Your Magician should show the following message on the screen. (There will be no backlight). This might take a few seconds to come up on the screen.
d. Press the “Power” button……..fingers crossed.

my O2 mini (singapore) appears :

what's wrong with it?

Most probably you have formatted your SD card or your SD card does not contain the image to be uploaded to the unit.

You can find additional info here http://forum.xda-developers.com/viewtopic.php?t=46628
Cheers, M

i did nt format the card.

as i said : i followed every step in the tutorial.it's based on picture.

Help for upgrading to wm 6.1 via SD card Flash

My USB Mini port seems to be damaged. I can charge the phone but when i connect it to my PC, the orange light lits and the phone gets charged but it is not found by my pc. So pls let me know how can i upgrade to wm 6.1 through sd card flash.
The solution is:
U need
ntrw ftp://xda:[email protected]/Magician/Tools/Backup_tools1/ntrw.exe
wm6.1 nb1 file http://www.mediafire.com/?sharekey=02c513f13b6fba677f7ec40ada4772a6e04e75f6e8ebb871
If the 1st method doesnot work then u need the backup of existing rom Click here to know how to back up ur exsiting rom http://wiki.xda-developers.com/index.php?pagename=BackupExistingRom
the hex editor http://www.hhdsoftware.com/Download/free-hex-editor-neo.exe
Method 1:
write to the sd card using
ntrw write Cotulla6.1.O3.nb1 F:
F: is ur sd card drive
There will be an error saying parameter incorrect. dont worry. Insert the card into the phone and enter the bootloader( Power+Camera+ SOft reset). A message will come asking you to press power button to flash. Press the power button and wait for complete flashing. in the end there will be a error that checksum failed . dont worry and do soft reset. Hurray u now have wm6.1 on ur magician.
Method 2:
If this doesn't work try this.( U should have a backup copy of ur old rom nb1 file.)
copy the first 416 bytes of ur old rom to the 416 bytes of the rom downloaded using hex editor
write the new rom to the sd card and install as in method 1.

It's not possible to install my rom via SD card.
Sorry, it designed for RUU flashing only.

I was wondering this myself...
Are you sure, Cotulla, that following this procedure would fail with your ROM?

Please someone try and if sucessful pls upload the .nb1 file so that i can write it to SD card and flash it through SD card. Thank you in adavnce

I can dump my ROM for you if you're willing to test to flash it.

please. i will try on my o2. thanks

Here it comes: click. Password is xda-developers.com.

the file appears to be too small only 23 mb . coutulla's rom was somewhere around 50 mb. will this work. i will try tomorrow as i am outside & donot have pc access

That's because of compression, the file itself is 63.7 MB.
I was planning to try this as well, but I don't have a memory card at the moment.
Keep us posted and good luck

As MusikMonk stated, this file is compressed and crypted with 7z. Haven't you heard of 7z yet? It's about time!
I doubt it will brick your Magician, since it's not overwriting the bootloader. Thus you can always flash you beloved old ROM.

While writing the file to the memeory card i am getting this as output.
NTRW v2.00
Removeable media
Cylinders: 0:120
TracksPerCylinder: 255
SectorsPerTrack: 63
BytesPerSector: 512
bufsize is 65536
WriteFile(): Cotulla6.1.03.nb1 -- the Parameter is incorrect
When i put the memmory card in my PDA and enter the bootloader mode only the screen with Serial and v.1.02 is there and there is no option to install press power button.

You must have done something wrong when filling your SD card.
I get that "press power to flash" message.
I hope someone will eventually try to flash that file... otherwise I made a lot of effort for nothing :-(

So does it work or not???

I used 1 GB Memory card. The Problem Might be because of than. Pls Letme know what memory card u used. Shold I used 64/128 MD card instead of 1 GB. Pls Help

64MB is a few bytes too small, 128MB is sufficient. I used a 256MB card... maybe the boot loader is unable to read much bigger cards... if my 16 GB card were empty I could give it a try... ;-)

I tried to copy the Cotulla.nb1 file on my SD-card, but it doesn't work. I used a 2gb and 128mb card...
I copied the ntrw.exe and the Cotulla.nb1-file to c://user/username. Then I write "ntrw write Cotulla.nb1 j:" in the black DOS-Window and press enter. j: is my SD-card.
Now there appeare some lines of text and I can wait about 3 minutes until there comes something about a wrong parameter...
But as I understand it, this should be no problem.
But the problem is when I try to take a look on the SD-card, there comes a window, that says that I must format the card. I cant open it... When I take out the card from the card reader and put it inside again, I can see what is inside on the card. But there is only one folder with the size of only about 130kb and no ROM...
My OS is Vista.
What am I doing wrong???

Magician boot loader does not expect any file system on the SD card, thus ntrw writes the OS directly to the first sectors of your card. When you insert this card now anywhere Windows does not find any file system and recommends to format. That is correct (as long as don't answer yes) and shows writing WM6.1 was successful (given your card is big enough and failure free).
To make clear: you shouldn't be to browse that card in Explorer when you wrote WM6.1 on it.

Ok but if I put the card out of the reader und back again I can browse the card and there is nothing except of an 130kb small folder...
And if I put the card into my magician on bootloader, nothing happens...
What could be the reason for that?

I tried with 256 MB memory card I am gettin gthe same message while writing to card.
NTRW v2.00
Removeable media
Cylinders: 0:120
TracksPerCylinder: 255
SectorsPerTrack: 63
BytesPerSector: 512
bufsize is 65536
WriteFile(): Cotulla6.1.03.nb1 -- the Parameter is incorrect
And when I enter the bootloader mode with the card Inserted I get the message:

update!
But with the same SD card when i write my old ROM( whic i had backed up) I get no error and when I insert the card and enter Bootloader mode I get the message :

Sections=1
Press Power to Flash
This means that there is some problem with the nb1 file . So kindly someone try it and post the results

one more thing. The backup.nb1 which i backed up from my sd card is 243 mb big. So i feel that the nb1 file which U extract from your card should also of around the same size and not 65 MB. Correct me if i am wrong.
I tried to extract nb1 file after writing ur rom to my sd card. it is also 243 mb big.
