Bootloader v6.22

I try to upgrade my wm2002 to wm2003 and halt half way. After the hard reset, the screen still show the upgrading screen.
Please guide me to flash my xda with the SD card in the bootloader v6.22 environment.

Should work the same way:

Hi LumpiStefan,
Sorry for my stupidity, i really been trying for the past weeks to solve the problem.
I have downloaded the XDATools into my PC and cook a Rom image of wm2003 with Asia configuration nk.nb1.
I have also imaged it into my 256M SD card using the XDATools.
I do a hardreset after placing the SD card into my XDA and got the wallaby bootloader v6.22 with GSM OK. I have to push the 3rd active button into to see the flash tools page. But it only display cd rom to sd, boot to sd, cd+boot to sd and gsm rom to sd.
What should I do next?
Thanks a nillion

Looks like the Bootloader didn´t notice the new ROM on your SD-Card.
Either you have problems copying the ROM to your SD-Card (Do you use an internal Card Reader) or they have changed something in the bootloader...
Try doing a backup of your ROM via Bootloader (ROM to SD) and reenter bootloader. If you get the option to flash your device you have a problem writing the ROM to the SD-Card. Otherwise it´s an issue with the bootloader...
Stefan

Yes, I do used a intergrated SD card reader to write the ROM to SD.
I can't backup my ROM to SD. Each time I try, it said Card Key Invaild...???
If it is the bootloader having the problem, how...????

2 steps in Upgrading ...
At first you have to downgrade your boot loader from 6.22 to 6.15 or so. Bootloader 6.22 will not allow flashing your device, unless you are equipped with the proper sd key. The way to do it is using the XDArit (I had problems with the new version in which protection of your hard drive has been implemented. You should write an SD with the wallabypatch (look at the FTP for the NB file..). a tip is when writing the sd with this patch, check the box of diagnostic). Than flash your device.. and you have to be quick and follow the instruction carefully... it will allow you to run diagnostic... which enable to flash the device. In summary for this section look for the wallabypatch instruction.
2. after you manage to write bootloader 6.15 , it will enable you to flsh you device with the new SD (written by XDArit ).
Good luck.

Dear kind Sir,
Is there any way you can show me how to downgrade the bootloader from v6.22 to 6.15?????
Can guide me through step by step.......Sorry.......

Excuse me, can you help me what to do if i lost for stupid my wallaby bootloader ... i only get parrot screen from T-MOBILE (number version, radio, etc... only) and i would back to life to my wallaby. it is dead 5 months ago :roll:
thank you too much your help.

Stuck in bootup
Guys,
I believe I have the same problem as the last post. I have several XDA's and one boots up to the "Welcome to TMobile" screen with bootloader 6.22, G324e4, R6.25.02, 4.01.16.
This is a Tmobile release with no ROM modification. I used a second XDA to start the bootloader and dump the ROM to an SD card and I then used this SD card to flash the ROM to the frozen device.
It did nothing, it is sill stuck on the boot up 'tmobile' screen. Any ideas?
Thanks Paul.

Try installing a PPC2002 ROM and if the device works normal downgrade the bootloader.
Maybe this is an issue of the bootloader 6.22
Stefan

LumpiStephan,
The two devices I have, one working one frozen, is stock from the factory, no modification of any kind, both have 6.22 bootloaders. All the self tests work fine, GSM, memory, everything is fine.
I have no idea of what it is waiting for.
Thanks,
Paul.

Thanks alot
I think this topic must be static at the top of the forum. You are great....

Flashing Via Mini Sd

While attempting to flash my wing via SD with these steps.
1 BackUp your Herald (if possible)
2 Format your micro-sd card with FAT32
3 Unpack the .nbh file of the Rom you want to use if needed
4 Rename the .nbh file to Heraimg.nbh and place this file, and only this file onto your micro-sd card.
5 Place the micro-sd card in your Herald
6 Put the Herald in bootloader-modus by pressing simultanious camera- and comm. manager button and performing a softreset. Keep pressing both buttons until the bootlaoderscreen appears.
7 Your screen will display the instructions to press the key on the left side of your device (slide the volumebar down)
8 Follow the instructions as displayed.
9 After flashing perform a hard reset as prompted!
10 Tada
Once I get to bootloader screen at the bottom for a split second it says "searching for sd card" but never finds it. Ive been flashing for a little bit back and enjoyed alot of Ferias work.Ive enjoyed 3Gen MDAs and have had three. Ive flashed via SD card on the MDAs and never had this problem. Theirs gotta be something Im missing. Any help or constructive criticism would be appreciated.

HELP: will pay for fix that works $.

Hi. New here. Done this magldr 1.12 and leo70 rom but my phone playing up badly after a lot of droid and 6 and other flashes. I can't install hardly any rom any more without it - ie: stock, wm6, android, wp7 rebooting constantly for no reason etc.
Done mtty and have bad blocks - about 16 and 16 reversed. done task 28 and task 28 55aa, and task 29 as read in other threads. tried everything with different radios, different nand droid. multiple wp7-hd2 installs. but still reboots.
Any thoughts? If go back to stock+spl1.66 and send back under warranty anyone know/think if they will fix it and/or replace it? they still have old sealed replacement hd2 stock or boards much? do they do diagnostics and look at bad blocks properly on warranty return? Even on stock-rom and stock-spl still does this reboot although not as much. Worried that stock-rom wm6 will "work" too well and they won't check blocks. What about task2a? etc? Any way to install wp7/magldr and partition right so no bad blocks counted in?
Thanks very much.

They will replace just flash stock rom and downgrade back to spl by using the hspl flasher, just select the spl. Call tech support and tell them it keeps rebooting and you reflashed stock rom 5 times. They will send you another hd2 and you'll be back in business.

Step by Step
First I am assuming you are an T-Mobile USA HD2 user.
Disclaimer: THIS WILL RESET YOUR HD2 DEVICE TO STOCK. NO HSPL
If not correct me.
1. www.tmobile.com/wmupgrade (Download the official rom from T-Mobile USA)
2. Once you have downloaded the file, extract the exe using 7z or WinRar. ( Right click on the file and click on Extract to ....) Downlaod Link Attached.
3. Reaname the Ruu_signed.nbh to LEOIMG.nbh
4. Copy the LEOIMG.nbh to your micro sd card, put the file in the root directory. (If the phone sits at the bootloader screen, try a smaller size sd card ex. 2GB)
5. With the phone off , hold the Volume Down while turning the phone on. Once you see the Bootloader sceen you can stop holding the buttons. ( Usually it will recognize there is a Flashable Image on the card, If not try again only this time let go when you see a Loading Message .........)
6. The phone will then prompt you to press Press power or some other button to flash.
7. Once your phone restarts go through the prompts if you want to click finish.
8. Put your device back in Bootloader Mode and Download HSPL3 (Attached Below) Next Put your device back in Bootloader Mode and Flash Magldr 1.12 & Windows Phone 7 ( Sure you know these steps, If not readme file included in the file)
9. Make sure the SD card you plan to use is in the device before you flash Magldr and Windows Phone 7. (Most are claiming a 16gb Sandsik Class 2 is working fine)
10. If you having restarts still, post what micro sd card you are using.
11. The problem lies with the Micro SD if you continue to have issues. ( Commong Windows Phone 7 issue)

tried all this, but to no avail. (on a europe htc hd2 512. 2.14.50.04 576 enabled. didnt do exactly as you stated but i did do the hd2 eur. equivalent of the steps) tried 2 microsd cards, the standard 2gb sd card that was in my phone package and a new Integral 8gb class 4 micro sdhc card. as soon as wp7 is flashed the phone reboots, magldr goes into 123456 gogogo! mode and shows dft splash screen. next, screen goes black and phone reboots. phone only loads wp7 1 out of 50 tries (avarage, went through the whole process of flashing, formatting, reflashing, etc. 6 times now) and suffers from random reboots (in sleep mode).
if you want to know how i flash leo70:
either from custom wm6.5 rom or stock wm6.5 rom:
boot in hspl2.08
run task29
flash magldr1.12
usb flasher mode
dwi.exe
>reboot<
magldr > 123456 gogogo!
dft splash screen
screen goes black
htc logo > magldr1.12 > 123456 gogogo!
and again and again until i get lucky and wp7 boots. i go through all settings, phone chevrons easily, phone installs everything easily.
phone battery goes empty/phone random reboots. and goes back into bootloop. when phone finally boots back into wp7 i might either have lost all settings (like a HR) or the phone has actually rebooted correctly and i can continue until the next random reboot. yay me.
any options? is it the microsd card? is it the flashing process? is it anything else i am missing? if it's the microsd card, i am getting an 8gb class 10 sandisk by wednesday so i can then try again. thanks in advance, i really like wp7 so i would love to be able to use it on my hd2.

SD Card
Backup your information.
Format the sd card using windows.
Choose Default Allocation Unit Size
And Fat32
Quick Format
Let me know if this helps.

This happened to me... I am on T-Mo US... i tried everyhting... all roms... hspl... stock... android... bla bla bla... but nothing worked...
and they replaced the phone for me... its your CUP i think... mine was doing it everytime i would turn on GPS or a location based service... If its been less then a year since you bought the phone it should be a free replacement... well for me it was... and if you have insurance... i dont know how its in EU...

My phone keep restarting all the time ....before i flashed new roms and didnt work. Then i took my battery out my phone and put it back and realized that the little hinges on the right side of the sim card was bended and face out so i pushed it back and place the battery correct and phone works perfect make sure you didn't bend the little golden hinges where you set your batter at

phone in wm6.5 (custom rom dutty's ml v12 dutch) > usb mass storage mode
format drive H: (8gb integral microsdhc card) standard settings. fat32 quick format. successful
task 29
successful
magldr1.12
successful
boot into magldr1.12
option 5: USB flasher
LEO70 dfi.exe
successful
reboot into magldr
12456 gogogo!
dft splash screen
screen goes black and phone goes into bootloop. wp7 boots after 6 retries
just in case this time the bootloop is an anomaly i change some settings in wp7 and reboot
once again bootloop. stop after 10 retries without getting into wp7. reverting to wm6.5 and keep searching for fix.
note: during full process 8gb microSD card was plugged into phone.
note2: phone did see 7.23gb of free storage space in settings>about
sadly this too did not work. figure it has to be the micro sd card?
edit: @nemo0405 do not have insurance, phone has always worked properly on wm6.5 never had random reboots nor did it have bootloops. phone was bought december 5th of 2009.
@that nicca it's not a power issue. in wm6.5 i do not have any problem with random reboots or bootloops.
edit2: have yet to try 2.15 radio in stead of my current 2.14. trying now.
result: sadly no changes in bootloop.

^^^ try it bend the 1 golden hing and sit the battery on it where it dont touch and put your phone on you gonna see your phone restarting every min .....i had that problem try it see if it works

Try to charge your phone straight 24hrs.that fixes the issue for me.

Go back and put the original stock rom back in, Then start again. You only need a 2gb micro SD. Dont know why everbody is using 16g? Its only used at booting in the Leo70 ROM. Use HSPL2 and change 2.08 to HSPL 2.08. Now put in the radio. I used 2.15.50.14. Now while still in bootloader mode, put in mgldr, and then when you see the menu, tab down to 5 and enter. once you have the gogogo and then Usb..Usb now flash in LEO70 rom. Now do you still have the loopy booty? If so, remove battery and re-insert. Looping stopped? If so go and set up the phone. If still loopy, remove battery again, now take out the sd card, put batt back in. Loopy stopped? If so set up phone. and if it sets up fully, then shut it down and put sd back in. If it goes loopy, then its the sd card. Make sure sd is formatted (FAT) before hand.
Let me know

After a task 29, flash first MAGLDR 1.11 then 1.12 ...or flash directly a stock rom. I remind that i read somewhere that MAGLDR 1.12 is an update of 1.11.

Remember too, that some sd cards seem to be incompatible with WP7. I have used a 16gb Kingston class 4 micro sd and an Adata 32gb class 2 sd card. These both seem to work. Check the thread about sd card compatibility, you might find your answers there.
Cheers...

If you phone keeps restarting AFTER you have installed NAND WP7 then your micro sd card is incompatable with Windows Phone 7. Most kingston and sandisk cards seem to work but generic and other brands can have problems which match yours. Reformatting the card wont really help, you need to get a sandisk card (you can pick up a 16GB card for about £18 on ebay) and it should work fine.
Remember though that if you use a new micro sd card that you will need to reinstall WP7 via Magldr as once WP7 has been flashed it sets up the card you have in your phone in a special way and therefore you CANNOT hotswap cards after that.

dude surely it can't be that easy for get a free phone ?
if everyone phoned and said they had 5 unsuccessful attempts of fixing an hd2 and got a new one everyone would have multiple hd2's and htc would die !!!

HI all. I am the OP and doing wp7 'hspl'/flasher/kitchen with other devs too; sorta know what I am doing (to a degree anyway, otherwise I pretend I know ).
Anyway THAT is what I am doing: it is being fixed at factory now: WARRANTY. No - they dont give out free phones - but 5 flashes story makes sense! I did this before even reading that post (told them did stock RUU many times). and yes, they should REPLACE your phone under warranty. also: no, not tmous and no, Sd card fine. Thanks for all response but tried everything mentioned here guys except 24 hours charge constantly. That I shouldve given a GO at least before sending in maybe. ???. Battery gets very HOT. (magldr!). battery pins are fine; done everything possible; incl task 28, 28 55aa, 29.
I even tried flashing with dwi.exe with 0kb partxx.bin files to 'clean' it as suggested here and even did task2a and recovered it with stock rom+spl (there are ALWAYS ways if you keep trying and never give up) and even done own JTAG!
Couldnt figure it out in the end as it just freezes/loops on DFT screen or ANY droid screen. Sometimes even reboots on SPL screen! dangerous hey!!!!!!!!!! (omg). even when watching cpu direct. ROM doesnt matter. multiple sd cards tried. either is BadBlocks, CPU, or contacts somewhere shorting maybe.
Ideas still appreciated PLEASE but they should replace it with new or at least new motherboard(+processor+ram) under oem warranty- thanks all. .

Thank you very much!!!
This works, but I didn't bother extracting the t-mos rom, I just installed it using the tmobile application that came with it.
I had 16gb sandisk (the one that came with the hd2) and I had no problems for 3 days. Before this I major problems pop up shortly after the first day.
Anyway, I just received my sandisk 32gb class 2, and I'm redoing all this hoping that it would work with this card as well.
Again Thank You!
Update: My 32gb class 2 Sandisk is running great!
Cheers!

[Q] Hard reset?

I'm looking to put android on my HD2 but I got a simple question.
If I install a NAND Android on my phone and I don't like it or encounter some problems can I get windows back with a hard reset or does that option get lost when I put Android on?
I got the tip to "You simply put the stock rom you want on your SD card, rename it to leoimg.nbh and then go into bootloader by holding Volume down while powering on."
I have tried to find info about this, can anyone point me in the direction where there is a guide/tutorial on how to do this it it would be very appreciated.
Thanks for your help!

No, a hard reset won't do the trick, you will need to reflash a winmo rom to get it back, as installing a NAND rom (even magldr) removes winmo.
You can find info here
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.

It's not cool to copy other people's things and publish as your own. So You bring yourself to the risk that someone might think you're very smart, and someone else that you are a thief. Link to other users post instead of copying it.
