Dear,
I have totally lost faith in new ROM 2003. 2 major bugs that I really cannot stand which are frequent SD card data loss (actually totally wiped out) and inactive screen (in case I turn off the screen, it will not be re-turned on by pressing the button, just have to soft-reset the device) :evil: . Could anyone suggest me how to go back to my previous version of rom 2002 which was rom 3.17.03. Please also advice me step by step since I am quite a newbie here. Thanks in advance
all u have to do is restore ur ROM from the backup that u made before going to 2003. write it to the sd card and load it via bootloader method. btw i'm running 2003 and don't have ur problems.

Dear,
First of all, thanks for your recommedation. ANyway, to be frank, I did skip the backing up step when I made the installation of ppc 2003 upgrade, so there is no physical data to back up. BTW, do you know any other ways or file formats besides RUU that might do the trick. I overread it somewhere in the forum that if we install via .BAT file, the downgrading can be possible without the bootloader method. Please help, and thanks again
last time i checked the only way to downgrade from 2003 is via sd card. u need to find rom file for ur operator. i have one for TMO in USA.

I much prefer the easy way of doing things and besides i do not have access currently to the facilities to use the boot-loader method, so i have always used the .BAT method downloaded from either Jeff or XDA people. I have successfully gone from 3.14.xx to XDA 1.1 to XDA 1.2 to WM2003 to XDA 1.2 to WM2003 to XDA 1.2 to WM2003 to XDA 1.2 to WM2003 to XDA 1.2 which is where I am know. The reason for so many changes is that O2 UK GPRS has caused a number of problems for me, although I did get things working over this weekend as far as GPRS was concerned, the disadvantages (for me) of using WM2003 far outweighed the advantages of XDA 1.2.
There is a point to this. From my understanding of things I've read on here if you go from WM2003 to an OEM supplied 'update' you could end up with problems, far better to go WM2003 to XDA 1.2 to OEM.
I hope this helps.

Hi there everyone.
I have just bought a new HTC Cingular 8525 but it is running windows mobile 5. I would like to upgrade but I cannot find any downloads or instructions on how to do so. I do not want to brick up my new phone. Does anybody know a download link to upgrade to the latest windows mobile version that will work on my phone. Its an american bought phone which is unlocked and I am using it in the UK on Three. It used to be locked to at&t and I am pretty sure much of the at&t rubbish is slowing my memory and speed of the unit. If I were to upgrade will the phone still be unlocked?
Rom version is 2.15.502.3
Rom date is 04/09/07
Radio version is 1.40.30.00
Protocol version is 32.73.7020.16H
Operating system is (build 15706.3.5.2)
I am all new to this and would appreciate any advice idiot proof I have flashed many PSPs and other things but nothing like this.
As I have just got the phone I am still trying to work out how to use it so I have no idea how to do a Hard or Soft reset and have no idea about the roms
Sorry to waste your time
Please help
Rob
You should read through the Hermes wiki: http://wiki.xda-developers.com/index.php?pagename=HTC_Hermes
Make sure you install hardspl! If you install the "official" AT&T WM6 install hardspl again, your phone will stay unlocked, even with custom roms. If you flash one of the big storage roms, then go to try another, flash the "official" rom before flashing another custom rom.
Read the wiki: http://wiki.xda-developers.com/index.php?pagename=HTC_Hermes
I would also suggest making sure your phone is "super cid" before flashing custom roms, you'll also be able to flash from an sd card if you are super cid.
Read a bunch before flashing any radio roms!!!
Read, read, and re-read before you flash, and you should be fine. They have made the process fairly straight forward, but you can never be too sure. I have never "bricked" my phone, and I jumped in with both feet!
Mustn't flash a lot then because if you did you will end up with a brick sometime... I've always been able to recover my Hermes but there is STILL the possibility it won't.... one day...

I guess I have been lucky, but I'm sure I haven't flashed as much as others on here. But, I tried to follow the wiki, and tried to learn from others mistakes before I made some of my own. So, I figure if I can flash my Hermes, others should be able to do the same. And I have read up on the issues for when you "brick it", just in case.
I flashed several roms from the beginning (when I got my hermes), and learned a bunch. Then found what I needed/wanted in a rom, and spent days and days and days reading through many threads to find ones that fit me. I actually tried not to flash too much, but that can be a hard temptation to overcome.
So, just trying to pass on what has worked for me, to avoid the hard resets and such.
I would like to attempt cooking my own rom, and have read through tons of info on it, and played with some kitchens. Still working on learning that stuff, it'll give you a good appreciation of what the chefs around here do.
Whenever i get to the update part of the software my htc turns itself off and disconnects?

I found out that its because I'm running vista. I tried to view Mr. Vanx's guide but its no longer there at this link..
http://www.mrvanx.org/cms/index.php?option=com_content&task=view&id=23&Itemid=27
So I am a bit stuck as I tried to do the following on here..
http://wiki.xda-developers.com/index.php?pagename=Hermes_UpgradeForBeginners
With no avail. It wont even let me install the HARD-SPL as it just gets stuck in bootloader mode with the error 260.
I have no idea what to do now. This process needs to be simplified more
http://www.mrvanx.org/thg/index.php?option=com_content&task=view&id=16&Itemid=26
Now make sure your device is on and activesync (or for vista users the WMDC) is running on your PC

I don't have anything running vista.

It tells you how to Hard SPL your Hermes with the sd card method. It also gives you ALL the apps needed.
After you Hard SPL your phone you can use the sd card method to flash a new OS. Flashing a new OS though requires you to drop steps 5 & 6 (you don't need sspl.exe once you have Hard SPL). Just remember though that the bootloader won't recognize any sd card bigger than 2gb...
Cheers...
Thanks for that. Its just now I have a problem where my phone is stuck on the Tri-Colour screen
Did you format the sd card fat32 (they are default format FAT) and rename the .nbh file to "hermimg.nbh"?
Is the sd card 2Gb or less?
You're on bootloader, is your SPL 1.09 des? If yes then insert the sd card and reset.
Cheers...
it might be an issue with activesync
i read somewhere before that activesync 6.1 won't sync with WM6 on vista machines.
I had to downgrade mine to ActiveSync 6.0 to get mine working again.
just an idea that might work
I've been having a few odd problems trying to get my C550 to flash a ROM of any kind using MTTY or Tera Term. I had been planning to reflash an old QTek ROM that I had on there, with one of the newer WM6.x ROMs that you guys have managed to put together. To recap, my C550 already has SuperCID, the SPL has been reflashed using Patched RUU and now reports 1.0.77 rather than the 1.0.16 or my other stock C550.
I can enter the bootloader fine and can connect to it using Mtty, making it respond to successfully to info and format commands, but when I try writing a new ROM, it just sits there doing nothing. I know it takes a while to reflash, but on my device it doesn't actually do anything even if you leave it for a couple of hours. The log looks as follows:
Cmd>l c:\rom.bin
clean up the image temp buffer at 0x8C080000 Length 0x01C40000
MTTYDownloadImage "c:\rom.bin"
:F=c:\rom.bin
start download​
The phone itself can be successfully reflashed using a ROM install package such as that of the old QTek ROM, or another T-Mobile ROM I have. The device can also be made to dump the current ROM to the miniSD card, so the bootloader seems to be functional. Which makes me wonder why this isn't working? I've tried flashing with and without the sim card, and also with and without an sd card in the handset, but it doesn't seem to make any difference.
If anybody has any suggestions of something else I could try, I'd greatly appreciate it! I had been thinking of trying to find an image dump of a WM6 ROM that I could then restore from miniSD, so if anybody would be able to that, it would also be appreciated.
Thanks for your help!

Please ignore the post above, I realised the SPL upgrade didn't seem to take until I used a different download of spl566wm6_spfans2006.nbf. Everything works fine now anyway.
Cheers for the wonderful work guys
i have hspl 3 installed and have installed custom roms befor on this phone.
my problem now is that when i try to flash new rom it gets stuck on 0%, i have tried from the sd card and using RUU Custom installer with no luck .
also i have done a hard reset, also have tried to install HSPL3 again even that gets stuck at 0%.
Has anyone come across this before and is there a fix.
You said "i have tried from the sd card and using RUU Custom installer with no luck".
Why do you use RUU installer when flashing using a SD card?
All you need is a SD card with ROM in it, and start the flashing from the phone.

If you get really stuck just re-flash the rom that the phone came with - i.e. the official one from your mobile operator - and you should be fine. You can find them on the net if you don't have it (e.g. on the HTC web site).
You can then start putting custom roms back on it.
Good luck!

Interesting, I'm having the same issue.
Grr.
Me too. I have rom 5.11.502.2 WWE, and I cannot get the RUU OR the Hard Rom flash to work.
This phone is a replacement for my Fuze that was stolen.
This newish phone is a WinMo 6.1 and I want to change the rom to 6.5-23568 Fuze Touch Pro.
WTF is making this stick at 0%?

if the version numbers you mentioned are correct, then you do not have a hd2.
Hey guys, I had this problem like three weeks ago, then got my phone working but this time it won't. What's happening is that when I boot on it just goes to a blank white screen. I have 2.08.HSPL etc. It usually works after a few battery pulls/soft resets but this time it isn't. I've tried running Task 29's, but they're stuck at 0%.
Everything I try do gets stuck at 0%. Well I've tried running a Stock RUU (RUU_Leo_HTC_WWE_1.48.405.2_Radio_Signed_15.28.50.0 7U_2.05.51.05_2_Ship.exe) and that got stuck at 0% too. I tried downloading my stock ROM off the HTC site but it says "Sorry, this software download is not suitable for your device." Why isn't it? My phones not a TMO HD2? It's a EU Leo bought from o2 Ireland. Can anybody link me to possibly the UK o2 stock ROM?
I downloaded a stock ROM from here but all that comes with the English WWE version is a .exe and not a .nbh.
I also flashed Artemis' custom ROM from SD card and that flashed etc. but when I tried to boot I get the white screen.
Any help appreciated, thanks.

Sorry to hear your HD2 is not working right now Skellyyy. I am with T-Mobile so I am not familiar with O2 but do they not have an official ROM on their website? Do you have to download your official ROM from HTC? I tried to pull up the o2 website but for some reason it would not let me pull it up. I went to www.o2.co.uk/ and I got this error message.
Error 502 - Bad Request

The exe is how you run the update utility for that ROM too by the way. Well atleast it is if you are using a computer to flash it. You have to right click on it and click explore to find tbe RUU file.
Also seeing as you have the EU HD2 why not just download the official update from the T-Mobile website and try it?
Yeah no I don't think they do. I looked on there and they hadn't got it. I think TMO have it on there website is because there's is a different phone then to the EU one.
Wouldn't downloading that ROM sort of brick my phone? Or would it not as the EU is compatible with all radio's?
I know the way you run the .exe then the RUU pops up, but HSPL won't flash anything. I've already tried. I know flashing from the SD works as I've flashed an Artemis ROM from it... but still had the screen.

Good point I have not thought about that. The hole thing about the TMOUS HD2 not being able to flash non TMOUS Radios probably does have something to do with it being there on thier website. This is an effort to keep people from getting confused and downloading the wrong ROM and bricking their phone.

No I don't think just downloading the ROM will brick your HD2, you have to flash it for it to even have a chance to brick it ha ha ha ha..........Just kidding I know what you meant, and no I do not think it will brick your pbone cause you have the EU HD2. You might get some preinstalled T-Mobile apps that you can not use but I think this would be the only side effect. But then again I was thinking you could flash it and then try to reflash your regular ROM as I know that the T-Mobile ROM should fix any issue you are haveing with SPL or the ROM. So maybe then you can get HSPL to flash sucessfully.

I also know if you flash the T-Mobile ROM via SD card it overwrites all, but I think this is the case with any SD card flash of any official ROM. The Artemis ROM is a custom ROM so if you are haveings SPL incompatibility issues it would not fix this as it would take an official ROM flashed via SD to fix that.

stuck at 0% usually means hspl is no longer there.
what does it say by 'spl' in bootloader?
If you have tried to flash a stock rom from sd card at all, , hspl will have gone EVEN IF THE FLASH DIDNT APPEAR TO HAPPEN, hspl will still have gone.
Your phone, if from o2, will always only ever take o2 stock roms, unless hspl is there. HTC website will only let you download o2 roms with that serial.
The .exe file the rom comes as is really a zip file, , right click and 'unzip here or extract here', or rename the file from .exe to .zip, , the file ruu_signed.nbh is inside there.
Artemis probably failed because of your radio and/or spl. tell us what it says in spl, and what rom you want to aim for, and we can take it from there.

Yeah no, that happened me before and I was only had 2.08.0000 but I'm sure I have 2.08.HSPL now. As I've said, it's happened before, in which all I did was do a soft reset and that worked. Doesn't seem to work now though.
I'm pretty sure MAGLDR is wiped now anyway, as when I plug a USB in while off it doesn't boot up, but just goes to a red LED. Is this normal yeah?
Just tried flashing the ROM I mentioned... the little progress bar showed... then the phone rebooted. Now it's back to SPL.
I don't there's anything I can do now is there? :/
ok, hang on, do you have a tmous, or a regular hd2 from t mobile?
I have a EU Leo. I don't know where it's from as I bought it second hand. The guy said it was bought on o2 Ireland.
Hey SKellyyy not saying I don't beleive you but just do this to confirm you have a DU HD2. I know for positive I have a T-Mobile HD2 as I bought mine brand new from a T-Mobile store. On your HD2 touch Start/Settings/scroll down to About Phone/Hardware Information. This is what mine says.

Compare yours and let us know.
if the send key is white its regular, green its tmous. yours will be regular, from o2.which is why none of those roms you tried worked. only ONLY o2 roms will work unless hspl is there, anmd as soon as you flash any stock rom using sd card, it will remove hspl and then teh flash will fail, but hspl is already gone.
so, to get..
a winmo rom
bootloader - hspl4 - 2.08.hspl (3.03.hspl if you want a 3.14 rom) - bootloader - radio (if needed to update, see the rom thread) - bootloader - flash rom
to prep for nand android
bootloader - hspl4 - 2.08.hspl - bootloader - radio - bootloader - magldr - magldr usb flasher - flash CWM
bootloader -
Lol dude I'm pretty positive as it only has 512MB ROM and it has no T-mo on top and the buttons are white.
I've already tried to flash HSPL again but that was using the second version of the software (can't remember the name) and it failed. It recognized the phone and let me choose 2.08.HSPL but the progress bar just went and went (for over an hour).
Where will I get a stock o2 ROM as the HTC website says "this software isn't available for your device"?

thats more likely the comp, not the phone. all usual things, reinstall activesync/wmdc, dont use 64bit os if you can help it, firewalls off, etc etc etc. easiest first test is use a different pc.
It was fine flashing CWM on Friday. Currently can't use a different PC, will get one later and try again.
Thinking if I get this fixed, I'm selling it. Too much sh*t happens with it. It's maybe just my phone but this usually happens everyday and a few battery pulls/soft resets fixes it. That by itself is annoying, but this is even more annoying.
hspl is different than flashing roms / cwm.
flashing and sync will work through any old usb port, rarely need to turn off firewalls, whereas hspl is realllly choosy. gotta be a usb socket directly on the motherboard, hates 64bit win, times out before the phone has rebooted if you start it from winmo running, isnt all that happy if you have changed teh usb drivers for that particular port, say for mtty, or android, (each usb port has its own drivers associated with it, thats why swapping usb ports if it fails is always the first step, try them all)
I've tried three different PC's. Two desktops and one laptop, all plugged in to motherboard USB'a but none of them are installing HSPL. They're all just going up and down on the progress bar. Should I try HSPL4? I'm using the HSPL3 program.
No computers are running 64bit btw.
Is there anywhere I can just get the o2 ROM and try flash it?
Yea go to HTC website, support, pick phone, downloads, change dropdown to rom upgrades, operator name is in the title. You can also find them in the official roms thread in rom development section, and elsewhere in various threads.
Keep gour head up!

Sorry you are having so much trouble out of your HD2. The HD2 is a great device but they are quirky as hell. I sure you will get it fixed, keep your head up man. Oh and don't give up on the HD2 just yet cause just like King Authur's Excalibure, The HD2 is a thing of legend.
Excilcior
Yeah, I'm currently looking to get a new HD2. Decided.
It's just the bootloader doing my head in, found the official ROM I need, but it'll only flash from PC and it's stuck at 0%. I need it as a .nbh so I can install from SD card. Do you know how I can do that if the RUU I downloaded is a .exe?
If you got RUU in .exe file install WinRar right click on the RUU file and choose "open with WinRar" then extract the .nbh file
