I have just tried flashing WM6 on to a Friends QTEK 8500, it went wrong Doh!!!.
I had already last Friday put on it the version with non wroking GPRS and this went without issue. I then reflashed my own one with a GRPS working version (went without a problem) and then tried his. I can get it into the boot loader screen but nothing else. I have tried SD card flashing (3 cards) 1x 512MB Card and 2 x 2GB card all formatted as FAT32 with file on the root the phone searches for it but doesnt find it.
Please any advise.

First of all, REMEMBER, your phone is NOT bricked until it goes to BOOTLOADER mode.
Have you made SuperCID before flashing? What firmware are you trying to flash via bootloader mode?

When you say booloader mode what does that look like. At the moment if I reboot the phone I get the HTC Mobility windows by Erofich screen.
When you hold down camera and record button and then power on the device I get brifely the white scrren looking for SD card it then goes to the tri-colour screen and does nothing.
I beleive I have CID it as I did the same on this as I did on mine i.e. ran the unlock according to the sticky.
I than put on this
Windows Mobile 6 AKU 0.5.0 (5.2.1711 Build 18165.0.5.0) WWE v5c

using the clean one which updated fine on my phone but when i tried it on my friends it fell over at about 83% I followed the recovery intructions but this did not work.
When you get into bootloader screen by pressing RECORD and CAMERA buttons, then you MUST flash back to the STOCK ROM first. You can't flash any custom WM6 at this point. Only AFTER you have the stock ROM flashed, you can use SDA_ApplicationUnlock.exe to app unlock the phone, and copy the SoftSPL into the phone. Then run SPL.lnk.
To summarize: The built-in bootloader CANNOT flash WM6 and can ONLY flash a stock ROM. Once you go back to stock, you can then try to flash WM6 again. Anytime a flash fails, you must go back to stock first, then try again.

This method works on Cingular ROM only, not Qtek.

Hold CAMERA and RECORD button and press power button. When it goes to Bootloader tricolor mode connect your device to PC and run official Qtek 8500 RUU. Then make a reg (app) unlock:
Download regeditSTG2 which is digitally signed: http://4pda.ru/forum/attach/387522/regeditSTG2.zip
Then install it and change some registry values:
HKEY_LOCAL_MACHINE\Security\Policies\Policies\00001001 = 2
-> change to 1
HKEY_LOCAL_MACHINE\Security\Policies\Policies\00001005 = 16
-> change to 40
HKEY_LOCAL_MACHINE\Security\Policies\Policies\00001017 = 128
-> change to 144
HKEY_LOCAL_MACHINE \Security\Policies\Policies
-> create new key "0000101a": Dword = 1

I have two phones one did work and one did not the one that worked shows version 1.02 on the tri colour screen the one I am having problems with shows 3.06 not sure if this is relevant.
Try removing the battery for about 30-seconds (or just removing the battery cover) and then put it back on. With the phone OFF, hold RECORD and CAMERA and plug in the USB while holding those buttons. It should go to the Bootloader. Run the QTEK RUU immediately after doing that.
If you sit at bootloader very long (more than a minute or so), for some reason it times out and the RUU won't work. It could be that's what's happening.

Tried that a couple of times just to make sure I was doing it correctly it goes into the tri colour screen I pressed the reflash option on the PC 1 second later this then sits there for a minute or so and times out "ERROR [260]" the phone did come on and has a USB in the bottom left corner so I presume the connection to the PC is OK.
I have just re-done mine again using the NEO rom (very nice) to make sure I am not going mad and that I did it correctly and this all went without a hitch.
Is there anyway I can get the phone to boot of a SPL on an SD Card I think if I could do this then I could get it back to 5 and start again.
No, it will only boot off the built-in SPL in ROM.
Did you try using the OEM .nbh file, naming it STARIMG.nbh and putting it on the SD card?

Yes tried that made sure formatted FAT32 etc. I know the SD card is ok because if I take my working phone and run the SPL link with the card in my good phone it finds the file and asks me if i want to reflash it. The non working phone with SPL3.06 does not do this.
You are not alone.
The bad news - the person in the post ended up having to exchange the phone.
It could be there's a bug in 3.06 SPL? Seems to be the case because I've flashed bad ROMs many dozens of times on my Cingular 3125 StarTrek and not once did I have any trouble flashing OEM ROM back on it.
Can I write the flash at a lower level with any tools i.e. pdocwrite or seomthing like that?
I don't believe so. Those programs require an Activesync connection (copies files to the phone). You could try the MTTY method, but I don't know if that works on StarTrek. I think it's some kind of terminal access into the bootloader, but what I've said so far is the extent of my knowledge about it.

I have a similar problem on a 3125 and the phone reports V4.01. I acquired the phone in this condition, so don't know how that came to be. When I try to update via USB, it tells me I need a newer update tool (to match the 4.01, I assume). What error message are you getting when you try to update via USB?
I have been struggling to flash (again) the great pro V2 rom, but I always used my VMWare based XP windows version on my Vista laptop. Today I could use a genuine XP Laptop and I could make a connection and start the upgrade!
Sounds good? That's what I thought too, until the upgrade stopped at 70% (and I didn't touch anything), because of a connection error. I followed the text on my PC screen and I finally it started flashing again for a few seconds and then my startrek suddenly restarted, but it stops at the first splash screen! I tried to get my device back to bootloader mode (push 2 soft buttons and start), but no bootloader mode, only the 1st splash.
I solved the problem.
Thank you for this thread
I tried flashing a new ROM to my i-mate smartflip and thought I had killed it, but going back to the wm5 OEM as suggested on this thread worked and I still have my phone. Now, am I brave enough to try upgrading it to wm6.1 (or even 6.5) again... Once again, many thanks!

Hi all, first of all I am no geek, I would like to unlock my HTC TYTN so that I may use other sims while abroad etc. I have read the instructions, downloaded v£a of the Sim Cid unlocker, however every time I run the unlocker my phone shuts down and reboots. I have tried with the phone without sim with none network sim with Orange sim same result phone shutys down and reboots. I have tried waiting till it is connected via active sync after rebooting but it nust keeps rebooting. I have even manually loaded the hard spl and run it on the phone but my phone shuts reboots and the spl has not been updated. Can anyone tell me what I am doing wrong?.
Thanks in advance Jimmy
info on device status tytn on orange
I have kept trying but still the phone keeps rebooting everytime I try to unlock. Device status uis as follows
operator version 24.181.1.612
ROM version 1.81.61.2 WWE
ROM Date 09/20/07
Radio version 1.27.12.29
Protocol version 22.45.88.07W
does any of this indicate I would have a problem using current unlock version 3a?.
Thanks in advance Jimmy
Check to see if the SPL has changed... Go to bootloader - hold power, OK above flywheel and reset with stylus. hold until tri-colour screen comes up. It will tell you your IPL and SPL.
It may already have flashed and that means you can update your rom with more safety.
Do you get any errors when running the pc? For instance [error 260](pretty common).
If that error keeps coming up you need to COMPLETELY remove activesync and then reload. All sync relationships MUST be deleted too. That fixed mine
Cheers...
I need some expert help please! I have a Hermes (Orange SPV M3100) that I want to flash with a custom ROM but I am having a problem with ActiveSync losing the USB connection at the point that the device enters the bootloader screen. I am also unable to flash using the SD card method. I have flashed a Nike without any problems and I'm usually good with technical stuff so I think there must be something extra I need to do that I have missed. I hope that somebody can spare the time to help me solve the problem. Here are the details:-
I am trying to follow Mr Vanxs guide to flashing the ROM in windows Vista so that I can upgrade it from WM5 to WM6 and apply a custom ROM to load a new TouchFlo style OS. The first step in this process is to flash HardSPL using this guide but my problem with the USB connection won't let me do that. I have unlocked the device using Hermes Unlocker 3a so it is (or should be) SIM and CID unlocked and be SuperCID with HardSPL-1.40 (so maybe I can miss the Mr Vanxs HardSPL step?).
So, when I run the RUUWrapper.exe, choosing the Force option and accepting the messages I eventually get a prompt on the device. At this stage ActiveSync is connected. I click Yes on the device and it enters the bootloader screen which shows 'USB' on the tri-color screen but ActiveSync immediately drops the USB connection. The update then waits for a while then fails with Error 260. I have to do a soft reset to get the device out of the bootloader screen. When the device reboots the Activesync connection comes back to life.
I thought that I maybe don't need to HardSPL first so I tried just going straight to the ROM upgrade but I get the same problem.
Also, I tried following this link to flash using the SD card instead of USB but when I get to step 6 I don't see a confirm message - just the usual bootloader screen (it doesn't help that the screen shot doesn't appear on the link so I'm not even sure if I'm getting the correct screen). Any ideas?
I realise that an answer to this probably already exists somewhere on the forum but I have spent hours trawling through posts and I can't find it so I hope somebody has come across this before and can help me out.
Thanks guys!
Don't worry I solved it by rebooting my PC, skipping the HardSPL and flashing with an official ROM (HTC_TyTN_WWE_3.54.255.3_6275_1.48.00.10_108). I can now apply custom ROMs.
Hello Everybody,
My mobile at&t 8525 alias HTC 8525 is stuck in windows operator logo.It would not boot further. It happened while I tried to upgrade it from Windows 5.0 to Windows 6.0.First I got a tri-colour screen,but in a hurry I tried to backgrade to windows 5.0 again.
Other problem the mobile cannot be synced. I have installed Microsoft Active sync 4.5. Even then it could not be synced.
I tried to read all the posts ,but could not understand anything.
So please help me in getting my mobile repaired
Don't worie.
I had somewhat the same issue with a bad ROM flash.
Just disconnect the USB and boot to the bootloader screen (the tricolour screen) and you should be able to reflash the phone again.
Problem in syncing the mobile
I am not able to sync the mobile to the laptop.I have installed Microsoft Active sync 4.5. Even then it is not syncing.So how could I run the hermes upgrade if the mobile is not helping.
Please help
In Activesync on PC - Untick "Allow USB Connections".
Put the Hermes into bootloader (tri-colour screen) and connect by usb. Run the RUU_Wrapper.exe file you want. Follow onscreen instructions.
You need to have installed Hard SPL V7 for this to work...
did not work
Hello Boss
I tried to follow the procedure you suggested me. but it did not work. I tried with Hard SPl 7.0.
Please give me some suggestion
you dont need an active sync connection to flash it. Enter bootloader(tri colour screen) as you were told in the previous posts and Just click on the boxes that you do have a connection(even though you dont) and then flash the rom.
@ultramag69 i hve never had to untick allow usb connections and i have cocked up loads of rom flashes, saying that i have never had a problem flashing in vista either so maybe i am lucky
If you still cant flash doing it this way, then maybe you should try flashing from sd card instead, just make sure the battery is fully charged. Full instructions of how to do this are found in the hermes wiki, which i advise you to read anyway.
Oh and good luck anyway, you should be able to recover the phone from this ,so i wouldnt fret too much
Guess he isnt hardspl'ed... then his batt is death... must to flash a shipped rom.
correct me if im wrong.
Problem with upgrade At&T 8525 mobile
Hi!
I'm having problems with my Cingular 8525, after I made the upgrade to WM6.1 (FARIA-R32-XDA2_WM6.1.rar) for WM 6.5 (FCWs_stock_like_6.5_v3.rar), and slowed my device does not work anymore. He died.
I need help please. How resurrect it?
Excuse my English.
english is not the problem here cause we need more info... device info SPL IPL hardSPL? you go from 6.5 to 6.1?
Do you try to flash first the Stripped?
Does your batt has charge enough to boot?
There are many many things to say so... start to tell us all your history!
Hi
I tried to Hard spl with Hard Splv7. But I got a error. I even tried the Sd Card method.Its says loading and I get the tricolour mode. If I press the Power button its not showing the status of upgradation.
Where can I get a shipped rom. Actually my Spl is 1.11.

check the wiki pages for your device in the upper bar of this web forums
there are many official roms.
I also am currently using an 8525 (Herm100). It was received from an Ebay deal with WM5. I flashed it with the ATT OEM WM6pro (aka shipped wm6). Once it hit the three color boot screen, it sat on that for a couple of minutes then started cooking. Once it showed a progress bar, it took about 3 minutes to cook the WM6 over the WM5. It also showed a popup that stated going back to WM5 was not an option.
I would suggest running the installer again and going down to 7-11 for a refreshment. You may not have let it percolate long enough to set itself up for the actual ROM overwriting.

Hello,
I'm about six hours into the process of trying to revive a nonfunctional HD2 that I purchased. I'm going batty!
Here is my status:
1) have installed SPL-2.08.HSPL 8G XE (0x05, 0x40) Cotulla HSPL
2) Have downloaded a few different roms (Chucky, TMO official, Energy) but they either get stuck at 0% or 9% (the highest it's gotten)
I'm getting pretty good at pulling the battery - it's like a new skill I never hoped to have!
I'm getting pretty frustrated because I've read about a hundred different posts on this site and I see that people are getting around this, but I'm starting to wonder if my phone has an issue that I can't resolve?
The phone doesn't boot up at all - it just says "Upgrade ROM code error, Please try again". Prior to my goofing with it, it just got stuck at the "Stick Together" screen. (Unwittingly bought it that way)
If I use the HSPL3_PKG to install/remove HSPL, it only works (connects to the phone) about one out of ten times, and out of the ~ten times I have gotten it to work, it only completed twice with a "We Hacked It" screen. The rest of the time it errors out just as I think it's getting the job done.
If I boot to the bootloader screen, I can put the USB cable in and see it change from Serial to USB (I've tried the thick and thin cables as some have suggested and haven't noticd a difference yet)
Then I kick of a rom update using the update utility that comes packed with it, and either the update process stops at 0% or it has made it all the way to 9%.
I'm in a position to get a replacement from TMO via the person who bought it (two for one, wife didn't like it, I bought it off of him) but I would rather not.
Any suggestions?
The part number of the phone is 99HKY001-00 B

Once you have Hard-SPL on the device you don't need to worry about that anymore. Flashing Roms and radios will not overwrite it, that's what makes it "Hard". To make sure it's on there go into bootloader and it should show 2.08.hspl.
As for the radio, for TMOUS, just make sure it's a x.xx.50.xx radio (not a .51) and you'll be fine. If you have radio 2.10.50.xx you shouldn't have to change it.
So now I would try downloading one of the stock shipped Tmo ROMs (2.13 or 2.14). Then remove Sim and SD and go into bootloader, connect USB to PC and make sure it says USB on the device (not serial) and run the ROM Update Utility (RUU.exe). See if that works.
i also got this problem ,will try ur method n c

HSPL done ,i tried a lot of files only Miri & Dinik n Duttys Leo Sense file can b flash successfully ,it went into menu once but now hang at htc startup again,,is this hardware problem?
i had the same problem last week. Drove me nuts.

you have to download the latest one. for more info,
read my posts at

So you need HardSPL3 (the version is DarkForces Team HardSPL3 by bepe and Cotulla 21.06.2010)
If it still doesnt work, take a photo and post your screen
Still no go...
I have installed SPL-2.08.HSPL 8G XE (0x05, 0x40) Cotulla HSPL, the latest version I could find.
I just tried to flash RUU_Leo_1_5_TMOUS_3.14.531.0_Radio_15.42.50.09U_2.14.50.04_LEO_1.5_Ship and it consistently flakes out at 8%.
I charged the phone all night, booted to the tricolor screen, kicked off the update as an administrator in Win7, the phone got to 8% and then the update flaked out on the PC - "The ROM update encountered communication errors during the update process" (Error [276])
I genuinely think that this phone is bunk - I'm just going to have the fellow I bought it from call in for a warranty replacement.
Thanks for your help, everyone...
SD card flash...
Hi,
I could not see it anywhere in this thread, and also I'm not certain if it is possible on a HD2. But on my xperia I'm usualy flashing from a SD card, copy the image over rename it as KOVSIMG.NBH (guess it would be something like LEOROM.NBH).
Than by pressing (and holding) volume down + power button while the device is off going to the boatloader screen which detects the card (must be inserted and flash from it IF there is the correct file loaded on the card.
Dude,
Did you actually download the HardSPL3 version from DarkForces Team?
If not, dont second guess anything. And if it works, you'll get your phone back.
The file name to download is "HSPL3_PKG.exe". Its by bepe and Cotulla 21.06.2010
If you downloaded the right version. it will support ALL LEO types, and all the SPL versions below:
SPL 1.42.0000
SPL 1.62.0000
SPL 1.66.0000
SPL 2.07.0000
SPL 2.08.0000
SPL 2.10.0000
you just select which SPL version to install in the Choose SPL screen. This version also disables the CID Check.
Dont knock it before you try it ..

Yes you are correct you can flash via SD card. You need a 4GB or lower SD card. This is not to say other higher GB SD card will not work, it is just that it has been stated many times the higher SD cards sometimes work to flash a ROM and sometimes don't. The card needs to be formatted with Fat 32. You have to find the RUU_(wharever).nbh and rename it to leoimg.nbh ( you almost got it righ tsnoffy lol) and copy it to your SD card. insert SD card into phone and hold the volume down botton down anx tap the power button keep holding the volume down button down until you see bootloader come up and say searching then let go of the volume down button. The ROM will flash.
