Hi All,
I flashed my HTC Fuze with the below ROM
Calkulin's Visual HTC Kitchen v4 for Touch Pro and my mobile is dead now. I missed to unlock the phone before running this update (although very clearly mentioned in the instructions )
Since the mobile is not booting I am not able to flash it with any other ROM or revert back what I did. Computer does not recognize the mobile through ActiveSync. I tried resetting the mobile (Power button + volume down button + OK button), it even says restoring to factory settings, but after restart still hangs at the AT&T screen.
Can anyone please help me out here or I need to take my phone to AT&T service, but that would be the last thing to do as I think the warranty is void with this tampering.
Well, I'm pretty sure that Calkulin cooks for the Herman (aka cdma touch pro). This is your problem (and maybe not your only one).
Flash a stock rom off your sd card.
Edit: Wow, that link takes you to the cdma Diamond forum at ppcgeeks. What were you thinking?
Thanks a lot Ted...!
Thanks a lot Ted. You are my "knight in shining armor". Atleast I have some hope, I think
You just said "Flash a stock rom off your sd card.". Can you please let me know or direct me to a post that tells how to flash rom off the sd card? I am however searching for the best fit for my set.
Also, I think i need to search for an appropriate ROM for my fuze this time.
Thanks again.
Um yeah...you might've just bricked your phone. Your best bet is trying to reflash your phone with an OEM ROM via a MicroSD card, then going to one of the cooked GSM roms on this forum.
Look at the stickied threads in this forum for the procedure and links to an ATT rom.
If that doesn't work, you could try going to an ATT store and playing dumb...there's a small chance they'll replace it under warranty if it hasn't expired yet. If all else fails...you might be able to score a fuze from ebay on the cheap...I'm sure there's a lot of people upgrading to touch pro 2.
Thanks for your reply.
streetlight22 and Ted, Thanks for your reply. I will try this today. Keeping my fingers crossed . If this works, I would be happier than ever (not because I could save some bucks.. but because I love my fuze and can't see it dying).
Every where the step says "renaming the ROM nbh file to RAPHIMG.nbh or something like that. I am wondering if I also need to rename the .nbh file to something before running the update.
The rom image will be named ruu_signed.nbh (if it's a custom rom) or something longer if it's a stock rom. You should try a stock ATT rom image. Just rename it, stick it on the root of your sd card (must be FAT32), and see if you can go into bootloader. If you can't get into bootloader, you're screwed. Remember to hold volume down for several seconds after soft resetting. Press it down before soft resetting. If the tri-color screen doesn't appear, you're in trouble. It should appear briefly, then go grey with a message like 'loading image,' then it will tell you to push power. But if you flashed a diamond cdma rom, you may have totally screwed things up. Most people seem to recover from cdma touch pro roms, but if it's from a different device, you may be screwed.
Hi, if the tri colour screen appears you can try flashing trough your PC, it should find new hardware (htc hot sync or similar), then there should be USB written in the lowest part, then you can flash watever you want from the PC in the manner you are used to.
It worked.. it worked.. my fuze is now up and running WM 6.1. Thanks to all...! Special thanks to Ted for his quick reply and the tip "Remember to hold volume down for several seconds after soft resetting. Press it down before soft resetting". This is what I was not trying inorder to connect fuze with my laptop. My set is back to normal, up and running cool...
Once again thanks to everybody. xda-developers is really really a life saver . Great job guys, keep going...keep helping newbies like us.... we really need u
Help needed.!!!
My phone suddenly started turning off today and did the vibrate then freeze on boot issue on me.. (overheating?? far too quickly)
so i thought ok .. i'll put a stock rom back on 3.14 uk (not actually able to download for my serial number from htc.com but i got it off the forum, original rom was 1.66 i think a few months back)
I did this and it still over heats..so i thought i'll remove hspl and put stock spl on to take it for repair/return sell to cex or something.
i got the 3.14 nbh and renamed in LEOIMG and everything was fine an seemed to be flashing ok..
it was at the red/green/blue screen for ages and the text did display spl.304 rather than hspl.. so i thought..cool..its done.. so i removed the battery and put it back in..
BAD MISTAKE!!
i get these errors issues now:
triangle with software update failed try again when i turn it on
0028022 "not allow" text when i go into bootloader
i cant load a rom because i dont seem to have hspl anymore
i get "upgrade rom coded error try again".. on the coloured screen in boatloader
i get critial error bad spl version when i try to use hspl2/3
when i try to flash with stock rom again i get to 2% then get the errors:
invalid vendor id error 294
then goes to software update failed triangle try again
am i basically f**ked???
Did i remove the battery mid flash during the spl bit?
PLEASE PLEASE HELP WISE PEOPLE!!

****.... tough luck mate....
As long as u got rid of hspl you should be able to get the phone fixed by htc or tmobilie or whatever plan ur on..
Good luck
bought it off ebay..so cant really take it to my provider..the phone is over (just) a year old so probably not in htc warranty? how do i check?
i will donate money to anyones paypal account if they can help fix this
Install the correct stock ROM (the one who match with your S/N) over SD.
how do i know which matches? and how do i do it via sd?

Put in your serial no of your phone (found underneath the battery) into the HTC support website and you will find the ROM that matches your phone. You will then need to download the ROM, extract it and take the .img file out of it and rename it as LEOIMG as before and flash via SD card.
shouldn't even need to use sd card. the correct rom should downgrade the spl over usb.
phone into bootloader,connect usb, run your update .exe, done.
you are guilty of getting over excited and lack of research. five minutes should have told you that you can't use hspl to install 3.14, and that flashing from sd first removes hspl,changes spl, then runs the compatibility tests again and shows exclamation mark if it fails.
I had the same problem i thought i bricked my htc which i was testing before buying i know stupid idea brick the phone before i buy it, basically i had installed hspl 2.08 from 1.42.00 and installed the froyo ROM build which was all good it was working but running really slowly, i couldnt get the ringtone to change which was probably due to the fact that the build did not come with any preinstalled which is fine as i downloaded a ring on mp3 and set it as that, and the radio was one of the latest which wasnt giving me a good reception so i decided, fine that's ok let me get my hands on some apps now so i downloaded a couple tweaks, multiboot and games and put them on my sd card; as well as a tweak to enhance the speed as it was going really slowly on the android, the second i put my sd card into the phone and tried running metamorph an app i was advised to use to apply a windows 7 mobile theme the phone went blank, the only way to get the phone into tri coloured screen mode was to plug it in via the FRONT usb port of my machine which would bring my phone back to life.........oh so i thought, so i was able to see the phone load up to htc white load screen and it would display my buil in red BUT after that it should show the "quietly something something message" and load right.....WRONG the phone just restarted and it would just do the same thing go to htc and restart so i managed to use the vol down+cancel call button to kick it into the tri coloured screen and managed to get the phone back into hspl 1.42.00 which completed but then i still couldnt get past the htc welcome screen!! ARGHH!!! So after spending a whole night applying different hspl's and trying to reflash teh rom via usb and failing i thought id give up and just pay for a bricked phone which i was paying £150 for btw (i know a bargain and brand new!!!) BUT as i came into work today i thought let me try a different pc as that may affect it, and after i downloaded an official ROM update for the phone 1.72 i i plugged my phone in and after literally 20 seconds the bloody thing turned on and started working as normal with no multiboot or rom installed i think i shall be CAREFULLY installing android on the phone one last time. . . . I hope this helped any users out there as i was panicking, and please remember that whatever you do is seriously AT YOUR OWN RISK, do not just jump the gun...sit down do some proper reading and watch some videos because after having to trouble shoot i must say im pretty good at applying roms hahahah i shall be very cautious from now on though. . .. sorry if the post was too long i am a noob my first post!!
yes.. i managed to fix it.. the same way kurt willems above mentioned... i installed the stock voda rom that matched my serial number.. kurt send me you paypal email and i'll bung a few quid in for your help..
gonna swap this phone for the galaxy s... good swap?
So u managed to save ur HD2 and now u wanna swap it?
keep HD2. Its great, and so many possibilities. U must know what ur doing, tho (kindof)
Also, his link for donation is everywhere. 'DONATE' 'DONATE TO ME' 'If you like my work buy me a beer'
haha..oh yes missed the donate button..
im a bit sick of the winmo set up... it's just abit too fiddly with soo many settings to mess with..plus the handset gets hot too quickly recently and turns off, vibrates when i turn it on and freezes... need to get rid before it gets worse.. cant be bothered with the hassle.... besides.. i like the android phones..so ill go back to them...
right im having some real issues now, i decided NOT to mod my phone again, because once my phone started up again i had to insert the simcard so i turned the phone completely off took out the batt and re-inserted the simcard and then it was bricked again (htc welcome screen, then restarts then back to htc welcome screen and repeat) after that i tried another go at installing the hspl again i just took a random version tbh and tried that as mine is factory unlocked uk htc, and then it failed i then took out the battery and notice that the spokes that connect to the metal part of the battery was a bit crooked so i carefully reseated the battery and hey presto its working again ( i can get into the phone home screen etc) so i quickly downloaded the origional spl from theunlockr"dot"co(m)/2010/04/22/how-to-get-the-htc-hd2-back-to-stock/ and installed it and then gave the phone a factory reset and now it seems to be back to how it would be if it was brand new but now im in a dilemma as i dont know which spl to use as well as what rom is best suited for teh spl and radio because i do not want to brick my phone again because if it does i will end up going back to the phone that has lasted me the longest nokia 6200 XD

Firstly you haven't bricked your phone. Bricking your phone means that it is reactive as a brick - it does not switch on.
To get the latest standard ROM, then go to the HTC website for your area, select the ROM you require and enter your phone's serial number. If you are entitled to use that ROM, then it will download. If not then you will get an error message. You may have to select your operator's version of the ROM.

Assuming, from your icons, that the HD2 is locked to O2; therefore you should be able to download the O2 1.72 ROM (no HSPL required) and it will not invalidate your warranty.
nope thats just what tariff i am using. . .Ive been looking around and now im qutie confused i thought the process for having android on the htc was literally
Download a hspl and install - reset
Download a radio and install - reset
Run CLCARD.EXE then HARET.EXE and presto were in android, now unless something has changed is this right because im about to.
Download hspl3 and install - reset
Download radio and install - reset
Download a ROM and install and - reset
now is this the neccessary steps or am i about to mess up my phone again =.=
It would be helpful to know which ROM, RADIO and SPL you already have.
As for running Android, all that is pre-required is that you have the minimum .50 RADIO (it should be specified in the Android ROM's page). Although flashing the newest RADIO (2.15.50.14) won't do any harm.
Although I am with T-Mobile UK, I have the HTC 1.66WWE ROM, 2.15.50.14 RADIO and 1.66HSPL (via HSPL2). I downloaded an Android version and installed it on the SD Card. It works fine. Since I only tried it a couple of times, I can say that it boots and generally works. But I prefer WimMo.

sorry for "stupid" answer,but...have you flash radio FIRST and rom than??I know,you're not a noob,but sometimes things more 'simple and obvious **** you
I had similar issues, it turned out to be a haware problem. HTC replaced the main board in the phone.
sorry to hear that
Just a 杯具
Yeah, you either need a new motherboard or use JTAG to reflash the bootloader..

I've been searching on how to completely restore my (T-Mobile) HD2 on this forum for a while and haven't came to it, so sorry if I'm repeating any threads.
Basically I'm fairly novice in flashing and things in that nature. I've been flashing updating Energy ROMs on my HD2 for about six months since I got the phone. Which was fairly simple to do. Since WP7 ROMs, I've switched over to flashing those. The problem is that 99%, it'll flash fine, then won't get past the boot screen. And on the rare occasion it does get past it, I can't turn it off, or else I'll have to trying getting past the screen 1000 more times to be successful. I think I have all the requirements to run WP7, but not exactly sure.
So I would like to know what to download and flash/ install for it to be as if I bought this from T-Mobile today.
Thanks!
I need help with this too..I craked my screen and am going to send it to t-Mobile so they can send me a new one, but I want to put it to factory reset. Ive looked all over cant find them...the post a couple up...links are dead
you do realize that if you cracked your screen your warranty is already void. it doesn't matter what software you are running at this point.

Sorry for MY late reply, but I put this phone away for a while and now my dad wants to use it. I've gone though the steps, but I can't get past "6. Hold the volume down key and power on your phone. As soon as the coloured screen changes to grey, RELEASE volume down." It never turns grey. I'm one step from taking this phone and throwing it out my window to see it shatter.

I have done a dozen of flashings on my Tmobile HD2 and works fine so far. Thanks to XDA forum all the tools I need are available right here on XDA !!! You just to search them out yourself (sorry I don't have the links ....... ).
I suppose you know how to flash your phone so I will not explain details how to do it.
In brief, to install WP7 this is what I suggest you should do -
1. Update flash radio to the latest available update from Tmobile US website, regardless of what ROM you have at present (version 2.15.50.14 is the latest, I think).
2. Flash HSPL 2.08 to your phone to maximize 576 RAM usage, if you have it (do not use SPL 2.08.000 as this will recognize only 448 RAM size).
2. Use Task29 to clean out the existing the existing ROM on your phone (this will erase your OS and you will only be booting on the white HTC logo screen). This will clear out those ROM leftovers on your phone.
3. Flash magdlr 1.12 or 1.13 on your phone (press power button on boot to show magdlr menu).
4. On magdlr menu scroll down to no.5 USB flasher, connect your phone to pc and run dwi.exe on your WP7 installer and wait till installation has completed.
I have done these procedures a dozen times already I have not encountered problems so far. I have been flashing and flashing to choose the best ROM (WP7 or WM6.5.x) I want. On personal note, I think I would settle for WM6.5.x cooked ROMs because of usability and handiness (I find WP7 too complicated to deal in terms of tweaks and handling of personal videos/photos file security).
Some notes:
a. You need to flash radio and HSPL only once.
b. Use Task29 every time you need to install a new ROM (your choice, but recommended).
c. After Task29 you can start out clean and flash to stock ROM or any other rom you choose.
d. There are dozens of videos on YouTube to help you flash but I have not seen one using Task29 to start the process of flashing.
This works for me, hope it does to you as well. Good luck !!!
Sorry for posting here, but there is no WinMo6.1 section for HD2. Maybe transfer the thread to WinMo6.1 subforum?
Also sorry, if I was maybe to stupid to pick the right keywords for search. Maybe I searched to complicated or noone was so stupid to want what I want.
Hi everyone. I made some stupid mistakes, and now my HD2's OS isn't booting anymore.
Preconditions
A HTC HD2 with open bootloader and installed Windows Mobile 6.1 ROM CrossbowHD2. There are some minor regedits for displaying japanese but those were no problem. Everything stable for half a year now.
What did happen?
Just wanted to install some software.
Japanese Advanced IME
Well, didn't saw the 'Raphael&Diamond' but there was no error while installing. After the installation it demanded a restart (no problem right), and since it doesn't boot beyond the white screen with the green HTC.
Guess it screwed up the registry.
BUT - and that's something good, isn't it? - the bootloadermenu is still working
What I want to achieve?
At best, full recovery without dataloss (no, don't have backups. Know myself it's stupid. Thanks). Maybe through reverting the regedits from the installation as can be found in the cab file?
Second best: Datarecovery via the bootloader through a tool or just flashing the original registry for backup (also the software won't work anymore) or some similar method.
Third: Memory dump? Is there a toll for converting the resulting binfile to something usefull?
Actually I just care about some of the note files, calender entries and pdfs. The pictures and similar may be lost if there's no other way.
Numbers:
Red booting numbers:
Code:
R 2.07.51.22_2
G 15.32.50.07W
D 3.14.04666 8G
Yellow bootloader numbers:
Code:
PB81100 HX-BC
SPL-2.08.HSPL 8G XE
0x05
CotullaHSPL 0x40
So, am I crazy, or is there a way?
I guess I'm asking for the impossible?
So other suggestions for solutions or another subforum to post this in?
Or, for a change, is there a android version which looks and feels like mobile 6.1?
Try booting you device and connect it to the computer if actvesync can recognize it you might have a chance if not i dont know any other way.
As for the android part try a gingerbread rom since it is the most stable and equal to wm6.1 speed wise but graphic wise waaaay different.Although jellybean 4.2.2 seem fast they tend to slow down after a while.You could always dual boot win mobile and android native-sd.
Well, thats the problem. It doesnt even come this far as to connect to active sync
Actually, after 5 minutes or so I get a black screen which states, that the device is unable to boot because turned off incorrectly or a installation from a "untrusted source" and to press volume up to factory reset or anything else to cancel.
I thought, if you can flash/write a rom there maybe also is a way to read from there
I dont like android from desktop to setting fiddling but, well, most software nowadays...
Is there like the bootmanager for linux and windows on the desktop something for windows and android for pdas?
maybe there is something like a "lightweight android" (like feather linux) to use just for 3, 4 programs ^^
Well i do not know any other way to recovery your data you could just reflash the rom by going into bootloader ( remove the battery put it back in hold vol down and power on) and flashing a rom.
As for Android rom you can run it with wm but there is no true bootmanager as such. You need to load wm then android there are plenty of apps that can act like a boot manager but they stiill require wm to load then once loaded give you a choice to run wm or go to android.
For a light android rom go with and CM7 rom personally i would go with Sundawg's rom it was the most stable cm7 rom and is pretty light
