Flash ROM From SD Card? - HTC Excalibur

Is it possible to flash a ROM Image from an SD Card like the Hermes?

It is possible!
Thanks for everyones help, but I figured it out. Flash is possible on the dash from the SD Card. Now I just need that wm6 rom and I'll be in business.

How did you do it?
In the same way described here: http://wiki.xda-developers.com/index.php?pagename=Hermes_SDCardFlashing
What .nbh file did you use? The one extracted from Original-Dash-ROM?
Can you save the SD-Card on PC with psdwrite/psdread?
Thanks in advance for sharing your know-how

Flash from SD using original TMO rom
This is what I did:
1. OPEN RUU_Excalibur.exe with an archiver and extract files to temporary directory (the file we want is the EXCAIMG*.nbh)
2. Format SD card using FAT32
3. Insert SD card into phone
4. Connect using ActiveSync
5. Rename nbh file to "EXCAIMG.nbh"
6. Copy EXCAIMG.nbh to SD card
7. Disconnect phone
8. Start Manual Bootloader (hold camera key for three seconds and press power button)
9. After quick messages (checking sd card, etc.) you should get "Update SD image? Press power button to download" screen with countdown in bottom corner
10. After timeout you will go to color bars UI
Exit bootloader: hold camera key, wait three seconds and hold down power key also until phone turns off
My phone is not unlocked, so I didn't test with other roms.

but excalibur has no camera key

SD Flash WM5 works SD Flash WM6 doesn't?
Ok, using the extracted nbh file from the original WM5 Dash ROM, I perform the following operations using the command prompt under windows:
1. Format SD card (FAT32)
2. Rename nbh file to EXCAIMG.nbh
3. copy EXCAIMG.nbh to blank SD card
4. copy any additional files to SD card (cabs, homescreens, ringtones, etc...)
5. Insert SD card into phone and power on while holding down the two softkeys
This method allows me to flash the phone back to WM5, but when using the nbh file from the WM6 Test ROM it will not work. Can anyone tell me why? WM6 -> WM5 works, but WM5-> WM6 doesn't. Is it the bootloader (same or downgrade only) or is it the signing of the ROM, could it be something else I'm missing?
Standard T-Mobile Dash (Not CID/SIM Unlocked)

I don't find on wiki how to flash a ROM Image from an SD Card to MDA Vario (Wizard). Can you help me?

Is the .nbh file talked about the bootloader only (~1.5 MB file) or the entire ROM image (~36 MB)?

is there anyway to boot from an SD card that doesn't require the use of the power button? Mine is broken and the rom seems corrupt on my phone.

can i ask why you would load the rom from an SD card when you state "connect to active sync"? if you have a computer there, that the phone is connected to, why not just use it to flash the rom?

Because my power button is broken and I can barely get the phone into bootloader. While in bootloader, active sync will not connect to the phone so I can flash it via my computer. Thats why I was wondering if I coud flash thru the SD card.

Thanks mate, your info above saved my unlocked athena (X7500) on which I had flashed a wm6.5 ROM which was faulty, and had completely taken over my athena, and refused to flash any other roms.
I have now reflashed with original rom before I try to flash other roms again.
Thanks once again.
PS. The last step does not work with Athena, what works is to simply do a soft reset by inserting the stylus into the reset hole.

helpp
does this only work with the original rom becasue i tries and it said invailid cerfiticate

I've done all the steps,but I still can't enter bootloader.I'm holding camera key for 3s,and then I press the POWER buttons while still holding camera key,but the phone start normally.Could anyone show me how to enter bootloader ? More clearly

Keep trying, you are probably holding too much time the power button.

For set bootloader pls poke strek (2 line ) for 3 sec and press reset for 1 sec.
But only upgrade with sD.
For upgrading press vol message and start win on flame for 3 sec and press reset for 1 sec.

I don't have microSD temporarily. Please, re-check this variants with card with inclusive ROM-image file (he located in your Extended Rom, file diskimage.nb0). For easy open ExtendedRom on FLAME, can use this cab: http://4pda.ru/forum/attach/1143435/Medush_FlameStorageOpen.cab
After SR you put new disk "Storage" - it's Extended ROM FLAME.
so that edit program list, which install after XR - remove any unnecessary program from CABList.txt.
I found an interesting thing.
If you enter in hard reset mode (clean boot screen), press and keep "no" button and IMMEDIATELY press and keep "yes" button: "image file not found" appears in a green colour message.
Perhaps taking a file NB0 in microSD, starts ROM update.
Is there anyone who risk to copy the file diskimage.nb0 and eboot.nb0 from extendedROM to microSD and try it?
I do not dare. In Spain there is no O2 technical service to fix it if something goes wrong.
Some things about this:
This works in my new PNY 2GB microSD but not in sandisk 2GB microSD.
If I formated PNY 2GB microSD in PC it not work
If I formated PNY 2GB microSD in canon camera it work
I think exist one relation between bootloader and SD formated sistem.
If I formated sandisk 2GB microSD in canon camera, now it work
And now flame detec it inmediately after soft reset

and from http://forum.xda-developers.com/showthread.php?p=1646965#post1646965
First photography from bootloader mode.
sorry, it is taked with N70.
Text in screen said "UPDATE EBOOT nb0 via SD CARD."
IMPORTANT: I used sandisk 2GB micro SD card formated in Flame with resco file explorer.
With this card in the Flame, push and hold pulsed at least for 3 seconds the 2 keys "-" in the flame, now you reset and hold the keys and waiting boot and hold the keys.
Do not release the keys "-" at any time.
Make backup before try it.

Thanks man, I've noticed you have a Claro logo below your nick. Did your excalibur came locked to Claro and with WM5 originally?? I was wondering if you know what original rom is the one for this phones?.
Thanks again
No it didn't, I have 2 Excaliburs, one is an HTC S620 no carrier and the other one an Unlocked tmo Dash. No Claro original ROM for the dominican Republic
cant seem to pass step 6!! wont work!!!!
it goes to the searching sd card but it only flashes for a sec then goes to the multicolor screen! iim so confused!
i have finnally got into the screenn and then it says
"invalid certificate"
What did i do wrong?
is your excalibur app unlocked??
Invalid Certificate message
I'm also getting this message, I have flashed previously (not from SD card) with no problem. I tried flashing through SD card since I'm dealing with a frozen screen that I can't fix due that I was trying to upgrade to the new WM 6.5 and I don't know if I locked again my device. I've tried everything posted on these forums to resurrect my excalibur and I'm running out of options. I can only get to the bootloader mode with no success with the original roms posted, my phone just throws me the "Invalid model error" or "invalid model vendor". Is there another way out?

Eten x610

Hello,
I Have A Glofiish x610,
This Time When I Had A Hard Reset, It Hangs While Installing The Rom Softwares, So I Soft Reset The Device...
It Doesn't Load!
It Can't Be Hard Reset Too!
I Downloaded The exe File From Glofiish.com For Updating The Os But It Needs Active Sync! My Device Doesn't Load So I Can't Use Active Sync
Please Help Me
hi there
try thees Steps
1. Run the ROM update program on your PC and go through the installation process until your reach the ‘End User Update‘ window. Leave this running.
2. Go to the Temp file in your Documents. This is usually C:\Documents and Settings\username\Local Settings\Temp but it really depends on how you set up Windows.
3. Look for these 2 files, temp.dat (about 60 MB) and USBDLUpdate_Console.exe (about 4 KB) and copy them to your formatted SD Card using a card reader. You might want to copy these files to another location on your PC before copying it to your card reader if there are problems. Also, rename temp.dat to temp.bin before proceeding to the next step.
4. Put this card into your device and put the device into Bootloader mode. This can be done by pressing (and holding) the power button and voice commander key and then soft resetting. When it restarts, you can remove the stylus but keep your hold on the power and voice commander buttons.
5. The installation will proceed but at a slower rate than if you did it on your PC. This is due to the slower transfer rate between the card and device. It might take about 15-30 minutes so it would be best if your device was connected to the mains charger.
6. Installation is complete when you see this message “USB host is not connected yet“. This is your sign to do a soft reset and setup your device as the ROM installation was successful.

you may use this rom

Help: Kaiser can't flash NBH anymore!

Following the instrcutions tp flash back to WM:rename RUU_Signed.nbh to KAISimg.nbh and place it on your SD card along with KAISDIAG.NBH. Place the SD into your Kaiser and hold the Power button and camera button down, then take your stylus and hit the reset button.", after I pressed the power button again, tri-color screen changed to a whie screen with "Loading..." showing. There was no progress bar below as usual. After about 5 minutes, I reset it, Kaiser runs android system well: I can even install a new anroid system. Just can't flash any NBH file, even Android small NBH file. Tried with a newly formarted fat32 card also. It always stop at "Loading.. " screen.
Anyboby can help me?

1st
I have never used the stylus reset to flash nbh. (good thing too because I broke it long before switching to android)
just holding the camera button while powering on gets me to the tri-color and then a white screen telling to press power button again to flash.
2nd
I have had freeze-ups on that screen while "loading" and it is usually because of a bad/corrupt nbh file or not making sure all caps in file name KAISIMG.NBH
just a thought...

Tried with KAISIMG.NBH, nothing different!
Anyway, Thanks!
Try clearing everything on the sdcard and leaving only the KAISIMG.nbh and remove the diag file too.
You should have one file (KAISIMG.nbh) on your sd.
NOTE: If the phone is off you only need to hold the camera and press the power button. If the phone is on just hold the camera and press the reset button. There's no need to hold the reset AND power button.
Since you can access the bootloader there is another way to flash, by USB.
You will need to do a little preparation.
If using XP disable Activesync by going to connection settings and uncheck 'Allow USB Connection'.
Then make a temporary folder somewhere handy, I usually use c:\flashtmp, but anything is good.
In this folder goes KaiserCustomRUU.exe, and the NBH renamed to RUU_Signed.NBH.
Once you have all this, put kaiser in Bootloader, it should say Serial at the bottom, attach the USB Lead, and wait until it say USB at the bottom, then run KaiserCustomRUU.exe and follow the instructions.
You should be able to flash Radio, splash, or OS with this method.
i usually do it the way zenity describes...its easier for me to keep up with all of my nbh
the few times i did it from SD i DID NOT have kaisdiag.nbh...other threads said it was unnecessary, so maybe its even bad
btw everyone i found that KaiserCustomRUU.exe will take a nbh named anything as long as its the only one in the DIR. found this by forget full accident
One thing zenity forgot to mention was that you need to remove kaisimg.nbh from your sd before putting into bootloader. Or just remove your sd

you can techically leave it there. in spl there is the option to not load the .nbh...after selecting that you can plug in USB like normal
Ah yes, I did forget the removal of the SD card, it may not be necessary in this case, but generally it's a better practice, saves confusion.
Didn't know about customRUU accepting any NBH though, always good to learn things
Regarding KAISdiag, I have never used it, so leaving it out is safe, in fact I'd only use it as a last resort for bad flashes or problems that require it.

Tried as your instruction with SD card and SIM card removed, when going to step to run KaiserCusomruu.exe, there is always a "communication error showed on PC screen, and recovery didn't make any difference.
I noticed that my SPL is SPL-3.34.0000, instead of SPL-3.34.0000. May it is beacause I flashed stock rom befored. How can I flash Hardspl in android system. I don't know how to copy jumpspl.exe to kaiser in android system.
You should be able to flash a stock winmo rom using the above method, since stock does not need HardSPL.

[X51V] The great upgrade guide

Here is a guide on upgrading an Axim X51v to WM 6.1, or WM 6.5.
This was originally posted on Mobilism.
NEEDED: Axim X51v (duh), PC (I don't have a mac and I am clueless about them) spare SD card (Min. 128 MB), SD card reader, charger (connected to cradle or via port, doesn't matter), and PATIENCE.
DISCLAIMER: I am not responsible if you brick your Axim. Use caution.
1. Get a ROM. Links are attached to this post (because the forum will not let me put links in my post >.<)
2. Extract the ROM to the Desktop. You will need to install WinRar, which I've posted a link to. Drag the 2 files in the box that show up after clicking on the RAR file.
3. Now, put the SD card into the reader and plug it in.
4. Go to My Computer, (Computer in Vista and 7), find Removable Disk (or whatever you named it) right click it and click Format.
5. When you get a box that is labeled: "Format Removable Disk" (or whatever you named it), under "File system", select "FAT32".
6. Click 'Start" (on the box), then click "OK" again.
7. Wait.
8. When you get the box that says "Format Complete", Click "OK".
9. Go to My Computer, (Computer in Vista and 7), find Removable Disk (or whatever you named it) and open it.
10. Find the .nb0 and nb0_.crc files on your Desktop (that you extracted earlier) and drag them to the SD card.
11. Eject the drive. (Right click on the drive in Computer and click Eject)
12. Place the SD card into the Axim and do a Hard Reset. (Hard Reset by holding the Power button. While holding down the Power button, use the stylus to push the reset hole and then release BOTH. Then, press the Contacts button.)
13. Go into the SD Bootloader by holding down the Power button and the Wireless button. While doing that, use the stylus to push the reset hole. After pushing the reset hole, keep the Power and Wireless buttons pressed.
14. You should get a blue bar at the top of your screen that says "SD Image Update A10_G*" (* for any number.) If you do, go on to the next step, if not, go back to step 13.
15. When the black bar with white letters show up, press the button in the center of the D-Pad twice.
16. Wait.
17. When it says "Update Complete, please do hard reset", do a hard reset. (Hard Reset by holding the Power button. While holding down the Power button, use the stylus to push the reset hole and then release BOTH. Then, press the Contacts button.)
18. Enjoy WM 6.1 goodness!!!
Oh yes, and if for some reason you don't like WM 6.1, I've made an A12 ROM (Original Dell).
This looks very similar to my X50 unbricking guides sticky over at Aximsite. I would like to inform you that this is not new information.
Anyway, you forgot to mention the part about checking the crc address in the nb0 file before you transfer the files to the SD card. For that, you just download the crc calculator and run it with the nb0, and then check to see if what the crc calculator spits out is the same as what's in the crc file. If not, than copy the value from the crc calculator to the crc file and save the crc file.
I would also like to mention that this process can be done on MAC OS X, but you have to mess with a partitioner to do it.
