HELP: No Bootloader after BigStorage Flash

hello guys, i'm really desperate now. my Magician is dead. i followed the laid out procedure 100% for upgrading to bigstorage. that's what i did:
- dump rom on to the sd card (512MB).
- got a external card reader (since the one in my laptop did not work with ntrw.exe)
- killed ActiveSync (wcesmgr)
- dumped the rom to my hard disk
- got Big_ROM_Ger_1.11.nb1 from ftp
- changed the first 416 bytes with ultraedit.
- wrote the resulting rom to the sd card with ntrw.exe.
- flashed (got the question in bootloader mode, pressed power).
- flash completed, got the 100% message and checksum failure.
- did a softreset
- my Magician is now DEAD !!!
Tried to put it in bootloader mode again, nothing! Put out the battery, unplugged and replugged usb cable, nothing!
PLEASE, any suggestions or help ??????

Please explain "nothing." Are you getting anything on the screen, blank screen, backlit, logo, text, anything?
Can you zip and upload your modified ROM dump file to dropload, rapidshare, or some other portal where someone can take a look?
Did you pull the battery completely, reinsert it, and pressed the reset+camera+power to get back into the bootloader?

the screen is absolutely blank. if i plug in the power cord not even the charging lamp is on.
i removed the battery completely for a few hours now, reinserted it just that moment and pressed reset + camera + power --> blank screen, no backlit, no logo, no text. i even used my torch to make sure i didn't miss the bootloader message. nothing.
when i press the reset + camera + power button the blue led blinks for a split second but then again nothing.
tried it with and without external power....
any clue????

rom i used

well, could be possible.... kinda teaches me not to mess around too much. i flashed my old xda II with magneto and all, never had any problems....
anyway, i will try to clear the backup battery over night and try it again tomorrow. if it still doesn't work, i'll get it back to the shop. it's brand new (2 weeks), so i guess (hope) it shouldn't be a problem.

No solution - but I had the same problem
Hello,
sounds that you have exactly the same problem I had. I also wanted to use bigstorage. First I updated to 1.06 official rom from T-mobile Germany. Then I used mksbigstorage to modify this rom. After installing this my mda was stuck at the splashscreen. But the bootloader still worked so I was able to restore my original rom.
Next I downloaded the 1.11 extended german rom from xda-developers ftp-server. I also replaced the first 416 bytes with the one from my rom. After installing this rom and doing a softreset my device was completely dead. No bootloader, no even a blinking light when connecting it with the power supply. I also tried to remove the battery for some time. But nothing worked. As I also had this device for just some days I finally did send it back and recieved a new one.
On this new one I also tried to modify rom 1.06 with mksbigstorage. But after that it was again stuck at the splash-screen. Mksbigstore seems not to work on this rom. Finally I was able to use bigstore by modifying two adresses in the original 1.06 rom downloaded from my device. This method is described in this forum. Worked without problems.
So I do not know what went wrong and I am sure I followed the instructions for flashing bigrom exactly, but as I am not the only one with this problem there is a risk flashing under certain circumstances.

I had the same problem flashed XDA 1 hundreds of times without problem. Flashed Magician device one time --> same problem as you have.
I've sent my device to repair center and they installed a new motherboard. So i don't believe that tehre is any fix to relive you're device..... :-(

I don't see anything wrong with the ROM file except for the fact that it's slightly larger than my ROM (65281k vs. 65427k). May have been a bad write to the SD card. Was your card a 64MB SD card?

On Monday I'll send it to the service center

Thanks for your response, kinda reduces my pain and asures me that I'm not a complete idiot....
I'm now pretty sure that I have the same problem as you have and that sending it to the service center is my only option....
At least I can use my Himalya with Magneto a few more days :wink:
I guess I will not try this again since I don't want to risk killing it again, allthough I allready had problems with the storage size on the working device (tomtom).
One more question: Did anybody ever had problems on upgrading from a t-mobile rom to a vodafone rom? is it even worth upgrading to 1.12?
Thanks for your help guys!!!

Dead phone! Microwave?

My phone refuses to boot winmo, it just gets stuck at a white screen (Its worked fine for 6 months, and decided to die today -_-)
So, I want it fixed!
But....
It will boot to the tricolour whatsit so it clearly shows 'coutullaHSPL'
But everytime I try to restore the stock Radio, or ROM is fails.
With the words :
"LEOIMG.nbh - FAIL" and "update terminate UPDATE FAIL"
In red writing.
Which is something, after over a year of doing this stuff on my HD2 alone I have never had happen to me.
So I cant take the phone back to stock, so no warranty!
So what can I do from here? Put her in the microwave so she wont turn on at all?

Tried it, and nothing! I've tried 3 different official roms now

When you are in Bootloader mode and your USB cable is plugged in what does the screen say at the bottom line ? Serial or USB ?
If you can see USB its all right. So take HSPL2 and run it, after that perform task29. Then try to flash customROM.
This is how it worked for me.

Serial
Sometimes it says neither!

actually had the same problem, its the problem with the sd card, what you can do is reformat it then redownload the rom and try again, should work.
Luckych

did you try copy leoimg to your sd card then boot the phone ?

u use T-Mobile stock rom?

Serial
Sometimes it says neither!

What´s your operating system ?
I´m using Windows 7 so i dont´t have the trouble to install the right USB driver´s...
If your device says "serial" there must be a porblem with the drivers... It has to show you "USB". Only then you will be able to flash it directly over your USB cable and CustomRUU...

It was news to me it was illegal, considering the amount of people (including staff!) who tell you to smash up your laptop to get a new one lol.
I explained that to another mod.
Sorry about that.
Well if anyone has any help on a fix, i'd be grateful!

I would do the following to get your device up and running again legitimately:
1. Take SD card out of device, insert into Card reader and then PC.
2. Download from HTC's offical website Stock ROM 1.66 (or even 1.43) with your S/N
3. Extract this RUU.....exe file to your desktop with 7-zip or Powerarchiver.
4. Rename custom.nbh to leoimg.nbh
5. Check if your SD card is not corrupt or damaged
6. If not, then copy leoimg.nbh to the root of your SD card
7. Remove SD card from PC and reinsert in the powered off device, which is not connected to your PC.
8. Press and hold vol down button and then shortly press on/off button. You should then enter bootloader screen and 1.66 will be automatically installed on your device.
9. At the end of the procedure there should be a message: installation succesfully. If yes, press the little red button beneath the battery to perform a soft reset or remove battery, wait 10-15 secs and reinsert battery and push the on/off button.
10. When the phone has booted up correctly after the SR, perform for extra security a hard reset.
When all goes as it should, you will have the the official 1.66 HTC ROM on your device.
Good luck and regards, Kuzibri

[Q] Help!

Hey guys,
Sorry to be a burden but I'm having a few issues with my hd2, and being a noob I didn't really know where to turn except this forum.
Basically my dad bought the hd2 from the UAE early this year and it all worked fine on stock settings for about 6 months. In the last few months, however, the phone started to lock up, and it got to the point where it wouldn't even boot properly.
In an effort to fix the problem I went with a hard factory restore, however, this seems to have caused more problems as now the phone is stuck in the bootloader.
I've been searching for hours, and have come to the conclusion that I need to update the flash? and then possibly install a new rom on the phone?
My major issue in doing this though, is that I can't seem to connect to activesync while the phone is in the bootloader.
Please help me sort this out.

First of all lets make sure that your trying perform the hard reset correctly.......
You need to hold down both volume buttons whilst the phone is turned off..... Then tap the power button and keep the buttons held down.......
Release them when you see the confirmation screen.........
Powering on while holding only the vol down button will take you to bootloader....
If you need to reflash the device then have a read of this thread here....
If its a "Tmous" HD2 (green and red call/hangup buttons) then you need to read this one
When connecting to the pc in bootloader you should see the word "serial" at the bottom of the screen change to "USB".......
Might be worth checking the text on you bootloader screen for any irregular looking characters, there have a few cases of people with corrupt bootloaders, usually these will display odd looking characters at the top. This is quite rare though.
If you want to flash another stock rom then you wont need to worry about HSPL just download the appropriate ROM and follow the instructions on screen.
Start off at the HTC site and input your serial number to see which ROM is suitable for your device.....
If none of that helps then hold out for some advice here from someone with better knowledge of these things.....

Ok well I've just tried to do the hard reset in the way you've described and had no response from the phone. I had to remove the battery from the back to actually power down the thing as nothing else seemed to work. I can't actually seem to start it up again now =S
Thanks for all the info, I'll keep trying to get it started. I'm downloading the stock rom from the htc site. Hopefully I will find a way to install that.
Also, when the bootloader was up, there weren't any odd characters that I could see. It all seemed pretty standard. It had the current rom driver which was 1.42 or something and a few other lines of info.
Thanks for the post.
edit: perhaps the battery is dead?

No problem.
Is it charging when plugged in and turned off?
If so let it charge while turned off for a while and then try to boot........
If you cant get to bootloader and establish a USB connection then you could try flashing the ROM from the SD card.
rename the rom to "LEOIMG.nbh" place it on the root of a freshly formatted (fat32) sd card and turn on the phone holding vol down..

To be honest I have no idea if it is charging whilst turned off =S All I get is the bootloader when it decided to turn on and that gives no indication of power level so I really have no idea. It makes updating a rom pretty scary haha.
So I just attempted to install the default rom from teh htc site, but failed due to the lack of activesync. It was strange though because the updater managed to change the screen on the phone and get to 1%. It then crashed and I had to go through this recovery process.
I will have to try this SD card process I guess. Could you perhaps link me to a more in depth guide to how to do this?
Thanks a lot for your help I really appreciate it.

you should get a red light up near the earpiece to indicate that its charging........
try this video for flashing from sd card......

I am not getting a red light flashing? But it doesn't seem to be running out of charge. I'm still having lots of trouble
It would seem that I need to install this hspl before I do anything, however, I can't install that if I can only access the bootloader screen. Does this mean my phone is bricked?
I want to be able to set up a rom straight from SD, however, I have no idea where to start. That video just seems to send me in a big loop.
Perhaps you could link me to a simple rom that I can attempt to load via sd card?
edit:
I seem to have somehow fluked an install of HSPL 8G XE.
I have no idea how this happened or whether it is good or bad.. but at least something has happened.

Hmmm
installing hspl is covered here
as long as the word "serial" is changing to "USB" on the bootloader screen when you connect to the computer you should be ok.......
You dont need HSPL to flash via sd card but I think that video was directed more towards people installing cooked ROMS from XDA.
Installing a stock rom will automatically overwrite HSPL so unless your planning to flash a custom ROM then installing HSPL is pointless........
You might be better off installing a cooked rom. (Artemis, Dutty's)
They tend to run better than stock, if you get one running then it will be easier to get back to a stock rom (if you want to) than the situation your in now.....
This is from the flashing guide;
Flashing Via MicroSD Card
NOTE (PLEASE READ): If you flash a Stock Rom via microSD Card then it will overwrite your HardSPL with a stock SPL included in the nbh file. This does not apply to custom roms as they do not include an SPL. BE CAREFUL!!
1. Make sure your microSD is Formatted to fat32 (you dont have to delete all files but it is safer if you do)
2. Download your prefered Rom from the LEO Rom Develpoment Page and unzip/unrar it to your PC
3. Goto the Roms Folder and rename the .nbh file to LEOIMG.nbh
4. Copy the LEOIMG.nbh file to the root of your MicroSD Card
5. Plug the MicroSD Card into the phone
6. Reset the device while pressing the volume down button to enter the BootLoader screen, you will first see a tri-color screen with the phone and SPL Information at the top
7. Follow the On Screen instructions to start the update
8. After flash has completed, press the reset button with the stylus to reset the device.

Reckon you could link me to one of those roms? I think we're getting pretty close now.
Your help has been great I can't thank you enough.

Your welcome
You can find Dutty's ROM here
or the Artemis ROM here
Have a quick read and see which one you think you'll prefer, to be honest I think they're both pretty similar to stock but with a lot of the crap taken out....
Just follow the steps in the first link I posted and you should be good to go.

Ok new problems.. Can you believe it.
I seem to have tried everything.
Basically I can install of a sd card, but when it gets to the end of the install and I restart instead of booting into a OS it boots to the tri colour screen, and starts the install process again.
Also, I have attempted to install via usb and have had varying success.
As I have already said, I am able to install hspl, however, when I try to flash I get to varying percentages below 30% before the whole thing freezes.
I now have an error that says Upgrade Rom code error Please Try Again.

Sorry i dont mean to hijack ! but will any of you be kind enough to help me here..
http://forum.xda-developers.com/showthread.php?t=879980
thanks !

Ok so I followed the steps and still to no avail.
I am able to boot using the sd card method, however, the same problem occurs with each rom version. Basically as soon as I reset the device it pretty much switches itself off, then I can't turn it back on, once I finally do turn it on, it restarts the process like it never happened.
The other issue is again the active sync problem.
With most of the the usb connections I am able to connect and get a little way through the install (most I've got is 15%) then it just freezes up and I get the 262 error

Your best bet is to try flashing with a freshly formatted (FAT32) 4gb, class 2 card.
I know, sounds pretty specific right?
You wouldn't think it would matter?
I have tried flashing with 16 gb class 2, failed at the radio step
Tried with a 8 gb class 6, failed at the radio
4 gb, class 2, flashed successfully.
Seems our HD2's are picky about what cards they'll take a ROM from for some reason.

Alright I'll try that, my next issue is which is the stock rom for the phone =S
It was bought in the UAE and I'm currently in Australia.
edit: Also I read somewhere that the constant bootloader screen can be caused by a bent battery pin?
Edit2: I have attempted to do that, however, now the bootloader will accept the card, then just sit on loading...
I'm pretty sure this thing is bricked.

I've heard of bent battery pins being a pretty common problem, causing usually just the phone not to charge properly. I've personally never heard of it causing constant bootloader, but it's definitely worth checking.
It's weird that it's such a common problem, my usb/charging port is broken, so I have to use an external charger. I change my battery on average twice every 24 hrs, and I've never bent a pin

Ok, new info, apparently because the device is for the middle east it does not support stock 3.14 roms. What does this mean for me? Am I bricked.

That's the post I found the info in. All of that info matches up to mine except my original image was 3.142 I think =S

Firstly, your phone is not bricked - a bricked phone is responsive as a brick.
Can we start from the begining?
What does the Bootloader Moder screen say (with and without the USB cable connected)?
What ROM (and if custom ROM, what RADIO) have you flashed and are trying to flash?

Alright from the beginning.
Basically about a month into using the phone in Australia it became very unresponsive to the point where it would not boot at all. We left the phone for a couple of months, however, after seeing a friend rom android I decided maybe it was time to attempt to fix this phone.
Some more info:
When I attempt to do any sort of ROM update there is nothing in the 'current image' part so for example it will say update to Dutty 3.6 but it's updating from nothing, does this mean there's no firmware there?
In the bootloader I have:
PB81100 HX-BC
SPL-2.08.0000 8G XE
MICROP(LED) 0X05
MICROP(TOUCH) 0X40
Without USB cable in I get Serial in the white part down the bottom, with the USB cable in + plugged into computer I get USB.
Just to further clarify. In regards to the ROM I have installed. I simply don't have anything installed. There is a bootloader, no image, no bootup. It boots up to the tri colour, that's it.

For a moment we will forget about going to 3.14 ROM: I don't know if that phone is entitled to an official upgrade to 3.14, if it is locked to a particular network, if it is branded, etc. If it is not entitled to a 3.14 ROM upgrade then you will have to go through GoldCarding, so we will leave it for now.
Make sure that the battery has had a good couple of hours charge in the charger or double that if connected to the computer.
Remove SIM Card and SD Card.
Switch on to Bootloader Mode, then connect to USB.
Download and run HSPL2 - ignore the instruction about connecting to ActiveSync etc, just proceed.
Download and install the HTC 1.66 WWE ROM - again, ignore the instructions, just proceed.
The reason for HSPL is because your phone may be operator locked (not SIM locked) and you aren't entitled to run the 1.66 WWE ROM.

Go into bootloader (turn of the phone, press the vol down button and press the power on button at the same time, wait until four color screen appear and see at the white color part the text "Serial". Plug in to your PC and wait until the "Serial" changes to "USB". Now you can flash it with winmo
Goodluck

Thanks for your answer but I knew how to flash rom with computer without you help .... you should read the other coments...
I have broken usb

You will need to place leo.image onto microsim assuming you have card reader which you will need since your usb is dead.
Then hold volume up and down whilst briefly pressing power on button. Then boot up from microsim which has leo image on it.
Do a search here on xda forums. Lots of posts on this form of rebooting..
Good luck..

What the hell are you talking about??
a) its leoimg.nbh not "leo.image"
b) Its MicroSD not "microsim"
c) You dont hold volume up "and" down, you JUST hold volume "down".
d) You dont boot "from" the image you flash using it.
People like you just confuse n00bs more.

[Q] Help on fixing hd2 that wont boot up

Hey guys I have a hd2 that wont boot up anymore. I have installed several windows 6.5 cooked roms into this device for a while now. Recently this device has been given me a lot of problems until finally it took a dump. Now everytime i power up the device it stays in the splash screen. It doesnt even show radio version, rom version,etc on the bottom left of the screen. So is this hd2 dead or is there some way that i can fix it. I even tried installing tmobile's official rom on this device by going into the "rainbow screen" so that the device can be seen by using the usb cable, but alas....it didnt work either. So any help would be appreciated .

If it doesn't install, and nothing installs, then you need to take it to repair I guess.

I had a feeling about that. I just figured there was no way to fix it and the fact that i couldnt send it back to tmobile to get a replacement was out of the question since the firmware was modified. But your saying there are shops that fix these kinds of issues? If so, I better start looking around over here.

why dont you try sd card method for flashing your rom !1! you can pm me if you need further help

Do you mean that it can't get to the boot loader screen (rainbow) or that trying to install a ROM from there didn't work? You might want to flash the original HSPL too, just to check.

What I mean is that everytime I boot up the hd2 it stays stuck on the splash screen. It doesn't even show the rom information in red at the bottom left corner of the screen. But I can boot to the tri color menu though. I have tried to install the tmous official rom by plugging the USB when I'm in the tri color menu and it always stays stuck at 9%. So is there way to fix this or am I screwed.
Sent from my Android Powered HD2 using XDA App

Try the sd-card recovery instead of the USB one.
http://www.jayceooi.com/2011/01/01/how-to-upgrade-htc-hd2-rom-through-sd-card-video/
After that, even if it fails, it shows only SPL in the tri-color screen then you are set to claim warranty.

Well my bro... i think thats nand problems or heating issues ... does flashing rom goes all ok or it stops during flashing ? if stops than check if you phone is hot - hotter than normal.
Try this : Take out battery, memory card, sim card and put you phone in the fridge for about 5-10 min ( dont worry tried many times... no harm ) meanwhile prepare your sd card to flash rom with sd card method ... to do that extract Ruu rom - stock one - download with hd2 serial nr ( winrar, 7zip etc) find Ruu_Signed.nbh rename it to LEOIMG.nbh than copy to sd card ( format you sd card fat32 and make sure it works ... 2gb will work ) take phone out from fridge put sd card & battery into phone power one phone while holding volume down key ( go into tricolor screen - bootloader) and follow procedure in phone... i hope everything goes well and you fix you phone... but if still no success than flash android or wp7 ( if you have warranty flash stock SPL and return phone).
best regards from me
