Restoring ROM and Extended ROM - JAM, MDA Compact, S100 Software Upgrading

Hi guys, I've recently upgraded my ROM from 1.12 to 1.13 (Glad that it was successful)
Prior to upgrade I made a back up of bought my ROM and the Extended ROM through the help of most of the post in this forum (Took time reading hehe!).
So far I'm enjoying the current upgraded ROM version.
But just in case i wish to revert back to my previous ROM version, could somebody or could anyone walk me to the steps by steps procedure to be undertake in restoring?
(Ive tried searching on the forum but with no luck)
I would highly appreciate any help from you guys!
Thanks and God Bless!

C'mon guys, please atleast point me to the right direction or links... =)
I have in so far the following backup files of my previous ROM:
- OriginalRom.NB1
- 96 Files i copied from my Extended ROM.
Really could use some help here...

Put the ntrw.exe and the nb1 file in the root directory of drive C: and Open Command Prompt then type (ntrw write OriginalRom.nb1 g: ) without the parenthesis and g: represents the drive letter of your card reader. after your rom image has been copied to the sd, flash it to your Magician the same way you flashed the Big Storage rom which is through Bootloader - then press power... thats it... im presuming that you do have a backup of your original rom not the big storage rom...

how to unlock rom on treo 750v - made by htc

we are trying to unlock and or dump the rom on the treo 750v. this is a newly released treo made by htc. the treo has an awesome feature called theeaded sms which does chat style sms.
we have tried the grab it program that was on this site with no luck.
does anyone no of a way to get this done? does any have any ideas of why the grab it program doesn't work. does anyone want to help?
thanks, cody
So far we've manage to get someone to try the grab_it tool from
http://forum.xda-developers.com/showthread.php?t=238945
But they are getting a write error. I assumed since the Treo 750v uses a mini-sd card the appropriate version of grab_it would be grab_it_128_minisd_468.exe. I'm trying to get someone to try the grab_it_128_150.exe version to see if that works, since that is the version BeyondTheTech used to extract the Treo 700w rom. The 700w uses a regular sd card though.
I asked the guy that tried grab_it_128_minisd_468.exe what the storage card folder name was set to and they verified that the registry was set to "Storage Card". So it's unclear to me why they are getting a write error. Maybe the minisd version expects something else? The card used was a 2GB minisd so it should have plenty of room for the rom.
Anyone familiar with grab_it know what is different about the minisd version? I read through the thread but it wasn't clear to me what the difference is.
Ok, I'm the one who's run the grabit tool on a 750v
It runs Ok and creates a 128Mb dump.bin file but the file appears to be mostly empty. If I zip the file up it only takes 147Kb which seems to confirm this. Am I doing something wrong or is it a bug in the tool
i have hope 750v user and appreciate your efforts

Can you upload the bin file please. I think someone here may be able to figure this out by looking at the contents of it.
If anyone has a source for a unlocked 750v let me know i really need one.

Hi, please can you do me favor? I have idea which can help us get SMS threading application and other palm features as well. If isn't possible dump ROM in this moment can you download Total Commander (freeware) http://www.ghisler.com/pocketpc.htm and do following.
1, Create foder on memory card and go to the Total commander.
2, go to the root of your device and copy to SD everything what is possible specially from Windows folder and Program Files (rest will be fine as well)
- this will take some time and in case of problem with file just skip that file.
3, When this will be done please go into the "\\" in the root and then to "registry"
4, now select registry tree one by one and copy again to card.
This will give us most probably files which will be required for hack and registry keys which will be required as well i think.
Thank you very much for your help.
Here's a zipped up copy of the dump.bin file, hope it helps
I extracted that dump.bin and it looks like a 256 byte block of data that is repeated at each 16 meg boundary 8 times.
Does this ring any bells to the experts?
The only readable text is "CHEETAH IPL EVT".
wow! that's great!
I don't have a Cheetah, but there's some info on the hermes forum that might be of interest to you:
http://forum.xda-developers.com/showpost.php?p=1019171&postcount=22
750v_User please try this program to extract the rom image.
unzip and copy TestDump.exe to your device and run it. In the "Path to file" enter the path for the dump file (i.e. \Storage Card\dump.bin). In the "Mbytes to dump" enter 128. Then press the "Dump" button. It should make a dump of the ROM file.
Zip it up and upload here. Thanks!

Thanks. That post appears to be for updating the rom. I wonder if there is some key combo like this to extract the rom.

Based on the Hermes experience, there's no knonw way yet to extract it in a form that after is flashable on another device, but you can follow these instructions to dump some parts:
http://wiki.xda-developers.com/index.php?pagename=Hermes_HowtoDumpRom
You can also use pmemdump to copy some of the ROM contents to a file. Once you've dumped SPL you can search for strings on it and you'll see the bootloader commands.
HTC has removed all the "d2s, s2d, r2sd..." and like commands in the hermes bootloader, probably you are lucky and you have some command to dump the rom to sd in your bootloader.
Hope that helps
The ROM dump // extract discussion is over my head...one question though has anyone sorted out how to unlock this device?

will that work????
just tryin to help........
what if someone get the .nbh file..can that be extracted??
750v ROM dump uploaded
I put a rom dump from the TestDump.exe tool on ftp.xda-developers.com. userid: xdaupload pw: xda
file: treo750v_dump_rom.zip
I used the dumprom tool to extract files, but it looks like it's only extracting the first rom section it finds and stops. Can one of the experts take a look at the dump and see if you can extract the other sections please.
Thanks.
What are you getting from the first rom section?
Sounds weird... was the dump complete?
It looked like a bunch of system files. The kernel, img.dll, filesystem drivers and the like.
There is 59MB of data in the dump so there has to be more stuff in there.

Extended ROM

hey Does any one have any tools to unlock the Extended Rom for my Magician (O2 xda2 mini), i wanna install some cabs in there pls do help.
1.Download Resco Explorer or Total Commander (cos you will need either these 2 program to enable "Reveal all files"
2. To unhide the Extended ROM, after you reveal all files, go to your File Explorer (Start, Programs, File Explorer)
3. Using the File Explorer, go to Windows folder and find this file called LoadVDisk.exe and then just run the file
4. Next, using File Explorer again, and go to \My Device and you should see the Extended ROM folder
5. Click on the Extended ROM folder and find the necessary cab file and click on it..
6. soft reset
also the search function is also quite useful. try it once in a while...
hey thanks for the advice will check on it, thank you.
hey man it works so how do i place another program in ext rom and will it be installed everytime i hard reset, and yeah since its unlocked how do i lock it again. than for the help hoping for a reply soon.
u cant place any new programs in the ext ROM. that ROM is supposed to be inaccessible to u. ur ext ROM should be hidden after the soft reset. check it!
You may not be able to place anything in the ExtROM till you unlock it. You have only "unhide" the ROM by running that utility. Till you unlock it you can only read the contents not write into it....
so tell me how do i unlock the ext-Rom of a magician, has anyone got any idea, pls let me know if there are any possibilities, i want to unlock the ext. rom of my O2 xda2 mini, pls help.
There are more possibilities read its content, (unhiding it). One possibility to hard reset it (pressing the Power button while pushing RESET). This will erase every data+programs from the device.
When the 1st boot finishes the ExtROM cabs are beginning to install. You have to Soft Reset the device (pushing RESET) to interrupt it. No cabs will be installed and ExtROM will be readable.

There are no unlockers for Magician AFAIK. But now most of the people go for big storage hack with which you get 27MB of extra space for storage. Put ExtROM on the SD card. Lots of material avilable on this forum for doing so..
what is the advantage of having a big storage other than ext.Rom, if i need to can i reverse the process back to normal.
The term “Big Storage” in a nut shell is the process of modifying the built in ROM file of the Magician and deleting its “Extended ROM” contents which frees up approx 20Mb of space. This new space or “Storage” can be used to install 3rd party apps etc and won’t be deleted after a hard reset. The only way to restore the contents is by “Flashing” the ROM again with a new complete ROM File. - excerpt from ampda guide
so what is the latest rom with the big storage for a magician. i surely would love to make a switch over. thank you.
The latest and last ROM for the Magician is 1.13 with Radio 1.12. Actually you can convert any ROM to BS.

Lost Usb Bluetooth connection after update

Well here I am stupified. I updated the ROM to a WM6 the phone works well with one exception USB and Blue tooth connections will not work. I am struggling with an sd card update ( to reinstall another rom) , but have failed so far. Any suggestions as to how to have my phone talk to th epc again. I can use the sd to get files back and forth. Obviously I am a novice.Txs
AT&T 8525 aka hermes,tyten etc,
What phone do you have?
Duuh, should have mentioned that
ATT&T 8525 aka hermes tyten etc
Are you using XP or Vista to do the upgrade?
In case you have a preproduction HERMES and you can not update the ROM (due to the fact that your bootloader is <1.04) here the very easy solution:
- format a SD card with FAT32
- extract the .NBH file from the rom image you like
- rename the .NBH to HERMIMG.NBH and copy it to your SD card
- put SD card in phone and start it in bootloader (hold OK button on left side and POWER button at same time and stick with stylus in RESET on bottom)
- confirm flashing on screen
- flashing might hang after some time but this is normal. Just wait. Complete flash takes about 30 minutes.
This also works for normal (non preproduction) devices but keep in mind that if the CID does not match the flashing might not work.
John
P.S. Same applies to other devices: BREEIMG.NBH, STARIMG.NBH, ...
(i didn't write this)
have a vista x 64 and a xp laptop
bootloader starts
screen shows
Herm100
ipl-1.04
herm100
spl-2.10.Olipro
serial
- format a SD card with FAT32
no issue
- extract the .NBH file from the rom image you like
can do, but only receive
splash.nb os.nb and sub splash file
- rename the .NBH to HERMIMG.NBH and copy it to your SD card
where is the .nbh file coming from? is this the org rom download?
what do I miss?
BTW Thanks for all the help

Just go to the Hermes forums and look for a rom that you like over there and download the package. More than likely, the zip/rar file will have the upgrading tools as well as a file called nk.nbh. This is your rom. Just do as nir36 said and you should be fine.
Good luck!
everything done as above sugested.
I cannot get past the multicolered page with the above mentioned information. ???
Herm100
ipl-1.04
herm100
spl-2.10.Olipro
depending of situation it says serial or usb
I left it their over night with no change,pushed ok buttons no change
what can i do??
did you use a different rom?
I assume you hardspl'd your device prior to flashing a rom right?
Before I did anything I used
http://www.mrvanx.org/thg/index.php?option=com_content&task=view&id=16&Itemid=26
from olipro to hardspl my herm
I then succesfully uploaded a vanilla 2d from josh. As the phone went dead( nirvana) a couple of timnes i tried to use a different rom
which i could upload, afterwards though the phone works but no bluetooth or usb connection hence no contact to activity sys and no restoring of my contacts.
Am i bricked or what is it. Can I somehowe eras all info and start from scratch?
MAin concern is I cannot get my huge contact list back in the phone
I have finaly got it to work fyi if someone needs it
I botted into the bootmaster connected to my computer and installed via "olliinstaller" a new rom told the softawre to ignore and safe hard boot.
It worked .
Thanks for all the suggestions and help

Ruu_signed.nbh

How to extract the .nbh file from my device? or where i get it?
Thanks for help
my device is a htc apache
Please read this even thou your device it's not the same, the procedure it's quite similar.
i dont understood
First download mtty.exe
Back-up you card via active sync or card reader. (i recommend 128-512mb).
Start your phone in bootloader mode.
Disable USB conection in active sync.
Connect the device.
Run mtty.exe, select USB, CMD> prompt should be displayed if not, hit enter.
Type (don't copy/paste) "r2sd all" and hit enter.
The loader will dump the entire ROM (including extended ROM) to the SD card.
Note that this is NOT a file on a FAT filesystem - its a RAW data dump with a signature and checksum. This backup can be flashed directly from you card.
thanks, but my question was because i wanto to carry xip and sys files to my dump rom to build a new custom rom. I have my dump and my extracted rom, and im stock in this step

[Q] HP rx1950 English ROM

first to post here
as i saw that HP rx1950 has got a Windows Mobile 6.1 Custom ROM..
but my device doesn't have the same language as the custom ROM pack, so i can't update it...
i've searched through the forum and the internet... there had been some ROMs posted,, but the links were dead already
anyone who still have this device, hope u can kindly extract the Stock WM5 English ROM for me
thanks a lot for your help, and sorry for my poor english..
martin
Just upgrade you phone, language of your current ROM doesn't make a difference .
Here is a kitchen ROM of WM 6.1 Classic for rx1950 from xda members Victory144 and Guifort.
http://www.mediafire.com/file/nna2yo92q2beiik/Flasher_Hp_Ipaq_rx1950_ENG_WM6.1.rar
I agree with tomcug. It should flash your ROM to WM 6.1 regardless of the language. You need to use it on a Windows XP computer with ActiveSync installed though...

I've read the post.. there're two methods to flash the WM6.1 ROM, by SD or through USB.. but i failed with a message "Wrong Image" after cloning the image to SD card, and the lauguage problem while flashing through USB with stock update utility (that maybe some lock by HP on language. mine is Chinese Traditional, but the update image is English..)
therefore, that'll be fine if the English Stock ROM is available.. btw, is there any program to flash that bypass the lock??
or how to change the language option of the ROM generated by kitchen?
i am not very familiar to configure the kitchen
thank you for your help
Here is a very technical discussion of 2 methods for installing different language ROMs.
http://www.tweaks2k2.com/How_to/39xxROMlang.htm
You will need a HexEditor:
http://www.mediafire.com/file/6r8ffn1fq3bh9mu/uedit32.exe
And a mtty program:
http://www.mediafire.com/file/7srppxvnr728ime/mtty11a.exe
BUT - at the end of method two when the author says - At the terminal screen type "lnb nk.nb0" at the USB prompt. (That means: Load the ROM nk.nb0)
INSTEAD - use the command "l nk.nb0"
That may be a typo - or the difference in mtty versions used by myself and the author...
thank you for your suggestion, i see that the ROM file structure of 3950 is a bit similar to rx1950, so i will try to change that
i've got the kitchen and the whole system downloaded from the site u suggested, but i just can't figure out how to change the language code of the output file while building the ROM , so that i can fool the ROM Update Utility and flash the ROM to my PDA..
wt's Build_XIP?
do u hv any suggestions? thx again
martin
Build_XIP... I think that is something for a different device. confused
_____
The following is based on research and guesswork. I make NO CLAIM that it will work and not damage your device... TRY AT YOUR OWN RISK.
_____
If my experiments with mtty and my reading of the How to install a different language tutorial are correct, all you need is:
mtty11a.exe to send commands to your iPAQ.
The English WM 6.1 ROM Image (CEOS.nbf) you want to upgrade to.
And Uedit32 to edit the ROM.
Put all 3 files in the same folder. It will be easiest to create a new folder on desktop with whatever name you like.
_____
This is for a Windows XP computer. That is what you have, yes?
First be sure to BACKUP your iPAQ and put all files in a safe place on your PC.
Next - remove the battery and any SD cards from the rx1950. Wait at least 10 minutes for the internal battery to discharge so that the iPAQ is cleared of all memory except the ROM you want to overwrite.
_____
Now we want to save the Chinese ROM you have so we can restore it if anything goes wrong. Best to be safe, yes?
Do you have a spare SD card at least 256mb? If not, use the one you normally have in rx1950... See why we saved all your files first?
Kill ActiveSync by opening Task Manager>Processes. Look on the list for wcesmgr.exe and wcescomm.exe. Highlight each one and click on End Process. With ActiveSync killed you can now "talk" to iPAQ with mtty.
DO NOT PUT IN THE BATTERY. Attach the iPAQ to the PC with the USB cable AND the AC Power Cord. Turn the iPAQ on and manually enter Bootloader Mode. (Google tells me for rx1950 you - press following buttons simultanously
Contacts + Mail + Reset for as long as your PDA boots)
Insert the SD card where you want to save the Chinese WM 5 ROM.
Go to the folder where you saved the 3 files you need and double click mtty11a.exe. That opens a box called "Open port setting." Scroll down the list in "Port" and look for \\\WCEUSBSH001. That is the port you want. I noticed that the end number (001) changes with each use of mtty. Never mind the number so much, \\\WCEUSBSH00x is what you want - that is your iPAQ. Select that port and click on the "OK" button.
It should open a command terminal (white window). Press enter until USB> appears in the window. I only needed to press enter once, but some tutorials say keep pressing until it appears. (?)
At the USB> prompt type r2SD and press enter. This will have mtty command your iPAQ to dump your ROM image onto the SD Card as RAW DATA. Wait for the progress bars on iPAQ screen to finish and you get a completed message.
Save this SD card in a safe place. This is your Recovery Image to restore the iPAQ back to the ROM you started with. The card is not formatted in a way that you can open and read with Windows XP so do not try putting it in a card reader right now - XP will want to format it and we don't want that to happen.
_____
If you need to recover your iPAQ at any point...
Unplug the iPAQ from PC and AC power cords. Remove battery and SD card. Wait 10 minutes to reset memory.
Insert SD card with Recovery Image. Plug in the AC power cord. Turn on iPAQ. Enter Bootloader Mode. iPAQ will see the Image on the SD card and offer you the option to Flash your ROM or exit. Pick the option to flash your ROM.
The iPAQ will Hard Reset after it flashes and then you can remove the SD card with the Recovery Image and do a Restore from the files you saved on PC and/or your regular SD card and the Backup we did at the beginning of this experiment.
_____
Now that we are safe, we can start to try and change the English WM 6.1 ROM so you can flash it to your iPAQ.
I read the "How to install a different language" tutorial quite a few times. Here are my calculations for what we need:
Original checksum
minus HexSum of ENG (45+4E+47 = DA)
equals change value
or
ECEC
-DA
= EC12
HexSum of CHT (43+48+54 = DF)
plus change value
equals new checksum
or
DF
+ EC12
= ECF1
Then that means we change ENG (code for English) to CHT (code for Chinese Traditional) and also change the Checksum from ECEC to ECF1 and we can get the ENG ROM to load on your CHT rx1950.
_____
Now you need to edit the ROM. Go to the folder where you saved the 3 files you need and double click uedit32.exe to open the Hex Editor. Click on "File>Open" and navigate to the folder where you put your files. Select CEOS.nbf and Uedit will open it.
10 lines down (line 00000090h) the file says "..........ENG.hp"
Next line 000000a0h says "iPAQ rx1950...."
This may or may not be the place to change - But I believe it is the right spot to tell any updater program what iPAQ version to update...
Scroll down to line 00000ea0h where it says "..........ECEC^a"
Next line 00000eb0h says ".e^a..........."
I believe that is the ROM Checksum and then an order to verify the checksum from iPAQ...
Scrolling down farther to line 00001ec0h it says " iPAQ rx1950..6."
Next line 00001ed0h says "00.00 ENG......."
I believe this tells any updater program what version is being flashed. But it may need to be changed...
So my best guess is:
At the first spot ENG is listed (line 00000090h) you need to edit ENG to CHT
At line 00000ea0h you need to edit ECEC to ECF1
Make these changes with Uedit32 and then click "File>Save as" and label the file "Test.nbf" saving it to the folder we have been using. (Note that mtty and any files you want to flash MUST be in the same directory.)
In Uedit32 click on "File>Close All Files" and exit Uedit32. Now you have 2 versions of the ROM in your folder...
_____
mtty still open and iPAQ connected?
If not - connect iPAQ as above (no battery or SD card, wait ten minutes, connect with USB and AC power, put rx1950 into Bootloader Mode). Open mtty. Navigate to your port and get a USB> prompt.
At USB> type in "l Test.nbf" (no quotes) and it should try to flash the edited ROM to rx1950.
If it was edited wrong you will get an error message something like "Header request time out."
_____
If it doesn't work that way it shouldn't affect your iPAQ and a Hard Reset should be all you need to restore your system. If that fails we have the SD card Restore Image we made earlier.
Delete the Test.nbf file from the folder and try editing CEOS.nbf again.
Try changing the Checksum and the second time ENG is listed:
At line 00000ea0h you need to edit ECEC to ECF1
At line 00001ed0h you need to edit ENG to CHT
Save as Test.nbf and have mtty "l Test.nbf" again
If it fails, delete Test.nbf
The last try would be by editing the Checksum and both times ENG is listed:
At line 00000090h you need to edit ENG to CHT
At line 00000ea0h you need to edit ECEC to ECF1
At line 00001ed0h you need to edit ENG to CHT
Save as Test.nbf and have mtty "l Test.nbf" again
_____
I hope one of these works for you. Please let us know what happens.
Thanks.
thanks for your suggestions very much!!
but i get the File CRC checksum error when using the stock update utility,
and through mtty.exe, it shows "Header Request Time out" also, in both i changed the first mentioned "ENG" to "CHT", second time and both times ...
all failed
would there any way to flash it through SD (by creating a suitable .nb0 file?) ?
hurray!!!!
i've cheated the HP ROM Update Utility (RUU) to accept to update an English ROM to a Chinese machine !!!
i use WinHex to replace the ENG with CHT, CHT with ENG,, and it's OK now!!!!
anyway, thank you very very very much for your sincere help!!!!!!!!!
Really marvellous!!!
HUZZAH and Congratulations martinhy!!!!!
I'm glad you got it to work.
I was at the keyboard for about 4 hours playing with the files last night and was afraid that my guess was wrong (as it turns out it was). So I'm really surprised and pleased that you solved it.
You just edited the RUU??? All other files in the kitchen folder stay the same???
Cause I need to cheat it and make it change from rx1950 to rx3115... I'll be trying your method soon.
it's troublesome to change ,, or i can say, cheat, the ROM file (.nbf) itself, coz it has checksum .. and the algorithm may be difficult to guess, and changing with different versions of iPAQ,
but the RUU itself doesn't have the integrity check, so it's cheatable
anyway, thx for your effort to help me
i can't be sure whether your guess is wrong, coz when i download the stock ROM, i.e. "l CEOS.nbf" to the iPAQ, through mtty, i also says "header request timed out"..
so i can't be sure whether there's problem for the way to edit the ROM, or the iPAQ doesn't support such mtty method...
or........
. becoz i'm a newbie, maybe i've got something wrong though...
*sigh*
When I try to change the RUU from rx1950 to rx3115 and run the rx1950 upgrade kitchen I get the CRC error...
When I try to change the .nbf and put it in with a rx3115 update package I get 244 Error (model ID)...
When I pull on my hair it comes out in big chunks...
I think I need a lot more study and a new toolkit...
that's maybe quite a challenge to flash ROMs from other models rather than language... both models are not compatible
