from dump rom to tytn - 8525, TyTN, MDA Vario II, JasJam Software Upgradin

Hi to all
Its possible extract a rom from a tytn and install this rom so other tytn???
or we must use the ship version???
if it is possible how can we extract a rom and how we can convert it to flashable rom???
Thx

Short answer: It is not possible yet, you must wait for a shipped version.
Long answer: A ROM consists of 7 parts:
1. Extended ROM
2. OS Image
3. IPL (part of bootloader)
4. SPL (part of bootloader)
5. Splash screen
6. HTC Logo (normally uses the same image as the splash screen)
7. GSM radio code
You can dump the original rom, but only the things contained in the FLASH will be dumped, this does not include the IPL, SPL, splash and radio parts, so its unuseful for flashing it back.
I've updated the wiki with this answer, see here:

Please Help
Hey pof.
I was wondering if you could point me in the right direction with my problem.
I've tried to upgrade my HTC Tytn original ROM to JasJam ROM , right at the end (99%) the updating software stoped , gave me an error and restarted the computer. Now all i see on my tytn is dots with mixed colours all over the screen(not even a tri-color mode) it looks like a broken tv. Now i can't even sync it with my PC to install old ROM. Can't do anything with it now. the reason for this i guess is a ROM update that wasn't completed.
I've tried to use bootloader but it didn't give an 'USB' option. just com1 and com2.
Please help. Iam really desperate

Does it look like this?

1) try SD card flashing:

2) If it doesn't work, put the unit in bootloader mode, disable activesync usb on your computer (Connection settings -> disable USB connection) and try to flash a ROM using the usual method.
Other than this... I can only tell you trying to get a repair under warranty

Hey pof. Thanks for the quick reply.
That is exactly how it looks !
Listen, somehow i've managed to get in to bootloader.
It shows on top:
HERM200
IPL-1.01
HERM200
SPL-1.04
I've tried to do the SD Rom update but it doesn't work. Just shows me the same bootloader screen with those two messages(above). Pushing the powere button doesn't do anything
The bootloader update didn't work either. when i typed in "set 14 0" it said "Write Nand Success" but when i soft reseted it , it still gave me that screen.
Any ideas what i can do? other then send it for repairs.
Thanks again.
Hope to hear from u soon.................iam freaking out here

Just tried SDCardFlashing with different ROM files.
With the original ROM it does not do anything (stays in the bootloader screen)
With JasJam (that's the one i've tried to install) it show "checking..." message on screen , but does not do anthing.............been like that for 10 minutes.
Can't believe i've screwed up so bad

At least bootloader is still "intact", the right NBH file should be the one matching your CID, assuming that you have a TyTN it should be the TyTN 1.18 rom.
If you can go into bootloader and send commands using mtty check your CID with command "info 2".
Also try to do a rom upgrade using the usual proces while the unit is connected in bootloader mode and activesync usb disabled, click on RomUpgradeUt.exe, then Next ,next, next... if it fails tell me which error you get and where.

---

Hey Pof.
when i try "info 2" command , it just hangs without any output. and i can no longer type in commands.
I've tried to run RomUpgradeUt.exe
This produced ERROR[222]: DEVICE NOT RESPONDING. I get it at the end , after the updater asks me for final confirmation.

Read this thread, from post #11 until the end
http://forum.xda-developers.com/showthread.php?t=278025
Try to put USB monitor (instructions on post #11) and see if you get any output from the device... attach the USB capture here if you want, I can have a look at it.

Hey Pof.
Did everything like you said.
Here is the output.
P.S: didn't allow me to upload WinAce archived files so i upload the text file, its pretty small.

The RUU sends "task 32 ; info 2 ; info 3" commands to bootloader, but you get no output from it, I think it's screwed because none of the three commands is answered by your device.
Normally, task 32 should return the seclevel, usually 0xFF ; info 2 should return the CID (in TyTN it is QTEK_001) and info 3 should return the block to calculate the dynamic password to be able to use wdatah command. Without wdatah you cannot flash
Do you have warranty on your device?

---

Yes its still under waranty , i purchased the device couple of weeks ago. Iam going to call them today.
Can you please advice me on what should i tell to HTC customer support ppl as to why this whole mess happend to my handheld?
Just wanted to tell you that i really appreciate your effort. Thank you for everything.

HTC has not "officially" released any rom for the hermes yet, the tytn rom we have on the ftp is leaked from dangaard NL, so you cannot say you've been trying to upgrade the rom because they will tell you there are no rom upgrades available yet.
If you are not in a hurry to have your phone back you can wait until they release a ROM upgrade and then tell them the "truth"... but i don't know if they will be able to see that you flashed Imate ROM and not HTC ROM (and flashing another brand's rom voids your warranty). If they don't notice it, the repair should be under warranty and no charges for you.
If you are in hurry, just tell them you tried to flash the imate jasjam rom (downloaded from imate ftp) and phone screwed, they will charge you some money to repair / flash back the original htc rom on your device and return it to you, but you'll have to pay because this is not covered by the warranty.
I don't know how much will they charge you for this, but you can explain them by phone and ask...
