Cannot Downgrade Rom From 3.16 To 2.17?? - Mogul, XV6800 General

I had 2,17 and upgraded to the leak rom 3.16. I did not use any locker or unlocker when upgrading. I am having issues with mail2web that it sends the same sent email several times. I think there is an active sync bug with the leaked rom. Anyways, I am trying to downgrade back to the official 2.17 and I when try to flash after the intial reboot it tell me error 328 invaild command
can anyone please help??

According to my sources, you needed to use olipro's unlocker v2 in order to upgrade the rom to 3.16 in the first place. I wonder how you did it?
I just got done putting the 2.17 rom back on my machine from 3.16 due to a ton of stability issues, not to mention I was downloading at approx 100kbps with 3.16 as opposed to 6-700kbps with 2.17.
Anyways...
You need to use the relocker program and then directly begin the 2.17 rom utility from HTC.
Be sure to remove and reinsert the usb cable when noted.
RELOCKER

nah, you dont need the unlocker if you never flashed a different rom to begin with. (stock rom)
to op, sounds like maybe you need to downgrade back to original bootloader...thats the best i can come up with.

thanks for the responses,
how do I get the oringinal bootloader??

i figure it out. For someone reason when you upgrade to 3,16 the device unlocks automatically, so i relocked the device with the relocker and the 2.17 rom flashed with out any issues. thanks

Did you have to go back to the original radio also?

Yep I tried to downgrade to 2.17 and had the same issue. All I did was hard reset the 3.16 and it cleared all my audio woes, so I never went back to 2.17. At least now I know why I couldn't. And no, you did not need to unlock to upgrade to 3.16

Find the relocker. There is a version of it that has the stock bootloader with it.

Unlocking with R6.25.02

Anybody knows how to unlock the T-Mobile XDA with this radio stack. I have downgraded by ROM to 3.17 but the XDAUnlock still wouldn't work. I get Error Getting Unlock Code. Based on what I see it does not seem to be a good idea to downgrade the RSU. If I do downgrade I can't find how to upgrade the RSU back to the current version.
1. Any help?
2. Will the XDAUnlock be modified to support this radio stack?
I agree with you it's not safe to flash the RSU, but if it's the only way then you will have to do it ... or it's better to get the lock key from your operator.
I downgraded the RSU...
Worked!
I tried unlocking the phone...
Worked!
Now I see no signal.... Do I have to upgrade the RSU again?
If so how can I do that?
thanks in advance for your help!!!
Upgraded Radio from uspocketpcphone.com and it worked!!!!!
HI. if you are trying to upgrade the radio stack, make sure that the radio stack is built for what kind of WM OS. For example, if you downgrade or upgrade the radio stack that you with Tmoble, make sure that the radio stack must support you Tmobile OS. I have tried may times and found out that AT And T just suits for AT&T rom, Tmobile, just for Tmobile rom, O2 must for O2 Rom. There is no way that you can swap one radio stack to another rom.
Again, I don't have radio stack 6.25 but I have radio stack 6.24 for Tmoble. I will upload if you need it.
Again, if you don't mind, can upload the radio stack 3.17 for me. thanks.

You were right!!!
I wish I could have read your post earlier.
I upgraded the radio on my own phone (i was working on my friends phone yesterday). Then there was no signal.
I tried downgrading to 3.17 (on yorch.net) and it froze and now my phone is dead. it restarted but it shows no radio version and no signal.
any ideas???

Reapplying same Rom version with SPL1.09..Invalid Vendor

Hi all,
I updated my Vodafone Rom to latest HTC HERMES_HTC_WWE 1.35.255.2 & Ext Rom. I am now running on SPL-1.09.
If i wanted to re-run the same ROM i would of thought that it would be OK as all is the same. I did all the unlocking before doing the upgrade when it was on original Vadafone Rom....
Reason is that i want to wipe and restart from scratch.
Thanks for any words of wisdom.
should be safe to reapply the same rom upgrade... but for what you say, you should better do a hard reset, no need to reflash again.

Thanks alot that has worked a treat.
Also is this a known issue or not - I actually had a full backup from the previous day and decided to restore that - but once it completed i was unable to get a phone signal god knows why - is this common?
using sbp backup
cheers

Quoting myself - how silly!
Managed top figure out how to use the Mtty.exe utility today and have discovered that the HTC_Hermes_SIM_Unlock_v2a.zip did not actually set my CID to SuperCID as intended but left it as Vodap001 - I guess the reason for INVALID VENDOR ID.
I have notice that the original ROM that came with the Phone has been uploaded - HER_VODA_1201616_1030600_UK_SHIP.exe which is BL1.04
I am to understand that i can apply this if necessary to Downgrade ROM and BL from current 1.09 -> 1.04???

Bootloader 1.09 DOES NOT allow DOWNGRADING of itself by means of flashing earlier ROMs. Once installed it is IMPOSSIBLE to DOWNGRADE SPL 1.09 to 1.06 or 1.04 by regular means!

But on this post where you mention of the Shipped ROM, you state
"Notes on this ROM:
This is the current shipping ROM for v1605 Vodafone UK devices, it has bootloader 1.04 and CID VODAP001, so it can be used to downgrade these devices to priced bootloader 1.04 "
But reading the post over the last week i was under the impression that the Bootloader would not be done - 'until i read the recent post mentioned above'.
Thanks anyway
Sorry my fault: only 1.06 can be downgraded by flashing a rom mathcing the CID containing 1.04 bootloader, 1.09 doesn't allow itself to downgrade. I edited the post you mention and added the "1.06" part now

unlock cingular 8525 ver 1.6

I have bought cingular 8525 with 1.6 version but its locked.Can anyone tell me how to unlock it free with no hastles. Thanks
Do you mean you have a bootloader version 1.06? If so, that is what I just did about 2 days ago.
Simply go to the TyTN wiki and find the list of ROMs. Get the Cingular ROM version 1.30 with the 1.04 boot loader. Flash that, do the unlocker thing that is stickied in the upgrades forum for the Hermes, then you can upgrade to whatever ROM you wish. I recommend the 1.09 bootloader ROM by HTC. It has the best performance out of all of them and it is now possible to downgrade if you want again.
BTW, once you unlock in 1.04, it stays with you nomatter what ROM you flash.
Good luck

Not true.
Once you CID unlock, you can flash ANY rom, but bootloader 1.04 will not stay.
Whoops
That is exactly what I meant, thanks Pof.

Restoring to stock AT&T rom?

I'm selling my Cingular 8525 and I want to restore everything (rom/spl/etc) back to the default from AT&T. Currently it has HardSPL and vp3G 3.0 on it.
If I flash the stock AT&T WM6 rom on it will that overwrote the SPL, radio, rom ,etc all back to the defaults?
This is the file from the wiki that I'm thinking will do the trick:
RUU_Hermes_CINGULAR_WWE_3.62.502.3_6275_1.54.07.00_108_UOOS_SVN05_Ship.exe
Thanks!
whoops wrong phone!
I did a reflash to that ROM after a WM6.1 problem and it does flash a different SPL, I dont remember which one tho.
When I flashed back to the stock WM2005 it did not change the loader. Just what I experienced, so you know.

I am pretty sire it will only change the rom, since that is what you are flashing. It will have no effect on the radio or SPL, as far as I know. But, if you are selling it, you can usually get more for saying its unlocked, so I would just flash back to the ATT rom and sell it...
that initial post is over a month old.

how to re-install SHIPPED STOCK ROM?
connect with activesync and click on the RUU_Wrapper.exe file.
You need to find the stock rom first. Flash the shipped stock rom. It has to be the shipped rom or upgraded wm06 shipped rom so the cid will match and it MIGHT reflash the radio rom successfully. If you try ANY stock rom it WON't work.
Cheers...
Make sure you Hard SPL your Hermes after. It makes it easier to fix if something goes wrong with a flash , I'd suggest trying to fix first then install Hard SPL V7.

I can not install any wm06 shipped Roms, the download stops at 11% to 12% or 13%, I even installed (HTC_Hermes_SIM_CID_Unlock_v3a) but downloading continues to stop I understand nothing !
Please help me, I do not sleep more than anything to retrieve my radio!
Sorry mate, if you can't flash the shipped rom it means the radio has been corrupted and so can't be used as a phone anymore. Flash Hard SPL V7 then any cooked rom of your choice to use as a PDA but the phone can't be recovered...
