hd7s bootloader brick

hi guys, I think i brick the bootloader.

I have an HD7s (AT&T). It came with mango.

I tried the OSPL, and i saw that the bootloaders didn't reach my version (4.x). So it gave me an error.

NOW MY BOOTLOADER WONT START CORRECTLY!

It only shows the first line:

PD29150 ss-bc (4k)

(nothing more)

And I can't load any rom now. nothing.

The phone starts ok, and works ok. The only thing wrong is the bootloader.

I tried to update from zune, but it says it has the latest rom already.

What do you think??

regards

Agustin

for issue SPL 5.1 cant downgrade to SPL 1.x ~ 4.x, it can using goldcard.

I same problem with this SPL before here and it can resolved using goldcard.

Goldcard is not to hard i think, you can make it by your self

I'm in a bit of a pickle here..

My PC92100's screen was damaged, so I had to send it in for repair at HTC.

Before I did this, I restored my original shipped (pre mango) backup from zune and sent it in.

They fixed the phone, which was nice of them.. But it now has 7.10.7720.68 with this spl:

SPL-5.10.2250.0(132274) MNG

Any chance I can still restore my pre mango backup from zune? Because then I can do HSPL.. Or will it not let me restore?

Thanks.

[EDIT]

It didn't work. It didn't let me restore my pre mango backups. I tried an older version of Zune too. Oh well.

Yes, because you have to put a fat32 formatted SDcard in the phone

Btw I think some here have managed to solve half brick with chevron unlock and cab sending method .

[Windows Phone 7 Development and Hacking] Magpir:
THe HD 7 has only one micro sdcard in the phone.

so remove that card means disassembly the phone and that voids warranty
[Windows Phone 7 Development and Hacking] Martin7Pro:
See my older posts. You have got "big" halfbrich without USB mode. 1st must restore USB mode (to "small" halfbrick), if possible. 2nd you can use "normal" way to downgrade SPL (exe from equal ROM, or GC). Full unbrick manual is finished in Czech language now, I am waiting to somebody English correction able. M.

Unbrick manual

Hi guys. I have finished first version of halfbrick solution manual . Czech original is presented on http://HTC7Pro.HowTo.cz/Unbrick/UnbrickCesky.htm , english translation will occured on WMMania.cz in a few of days. Some parts will changed, becouse any new methods confirmations are not included still. If somebody cannot wait to finish english version, he can read authomatic translation (but see wrong formatting) here: http://translate.google.cz/translat...p://htc7pro.howto.cz/Unbrick/UnbrickCesky.htm

Is there anybody able to make English language correction of finish version? Send me PM, please.

Sorry for my bad english
[Windows Phone 7 Development and Hacking] Martin7Pro:
When you are in "big halfbrick" state, you cannot flash ROM by USB port (only JTAG way is possible), because USB mode is not present by corrupted bootloader. First aid is OEM Update resending. This may unbrick your phone, or unbrick to "small halfbrick" state, where USB mode may be forced. Why do not you read any posts here about problem? Read my immediatelly previous post, there is first beta version of unbrick manual. This is compilation of older posts only.

Edit: For another people - do not use next method before 100% confirmation! I have got this tutorial as part of my full unbrick manual from one man and I have success confirmation from any next people in last weak, but they have not all devices/brands/region. Error may be in part "remove RUU_Signed" with using any different RUU packages. Wait, please, rdia and Magpir have probably problem with using it.

1st try ROMUpdateUtility (must download equal brand/region Ansars signed ROM for your device with lowest number) from PC with SPL_Signed.nbh only (remove RUU_signed and other nbh files from directory). Try it in backup mode (Black screen with computer picture, hold shot button after phone restart), if no success, also in USB Host mode (White screen, hold volume down + shot button after phone restart). If no success, try more difficult methods (Y-cable with simplified or full GC, change card by GC, send to XTC/JTAG repair service). This is the same, what I have wrote in last post, read detail links.

ATTENTION! Flashing needs full battery everytime. I know much people with fullbricked phone by this reason.

EDIT: Do not use it! It is big mistake, read other posts.
[Windows Phone 7 Development and Hacking] Magpir:
I think u are on crack, i have a hard time believing yr stories.
[Windows Phone 7 Development and Hacking] Martin7Pro:
What is your problem now?

Edit: I mean I know after quick discovery. Opposite much ROMUpdateUtility success confirmations I mean this cannot work for SPL 5.xx! You are right, I must be on drugs. I have wrote here what somebody send me and others confirmed, but it is danger for much devices. Can you write, what is your phone status now?
[Windows Phone 7 Development and Hacking] rdia:
I'm worried already, did not screen beckspe cpreta computer error (260) conetion and so also error 240 white screen.
[Windows Phone 7 Development and Hacking] Martin7Pro:
Please write more here or to my PM. What is your device brand/region, what is used ROM file. Have you really equal? Have you full battery? Flashing was begin and error is occured after any time (any success percent occured), or immediatelly? System is booted normally now? Battery, PC/laptop power, carefully included USB cable and equal SPL file brand/region is very necessary. When SPL flash crashes about 1% to 9%, you can fullbrick your phone. Have you read all warnings, also from used ROM package. Post also your lines from Settings/About/More information.

EDIT: Opposite all this method success confirmations it is probably very wrong for SPL 5.xx. This is only one part my unbrick manual, which I have not tried myself and use only others success confirmations. After quick discovery now I must write this cannot work with SPL 5.xx and it is very danger for any devices. What is your phone state now?

[Windows Phone 7 Development and Hacking] Martin7Pro:
Yes, I see. But, what is your phone state now (after ROMUpdateUtility crashed)?
[Windows Phone 7 Development and Hacking] Magpir:
My phone is still. Fine and working fine .

No brick .

I tried the rom update utility many times and it never bricks my phone.

Because i am on stock mango. There is safety protection in it as boot loader is original 5.1 will not allow further proceeding of flash .

Maybe those people who had it bricked had something different about their phones, ,maybe they bought a 2nd hand half brick phone , or has hspl , forgot to remove RSPL/hspl ect.

---------- Post added at 01:16 PM ---------- Previous post was at 01:14 PM ----------

Yr phone bricked because u used the wrong rspl version .
[Windows Phone 7 Development and Hacking] Martin7Pro:
Thanks for info. I am happy you have not fullbrick, but I must wait for rdia post about his phone state. I had tried ROMUpdateUtility on my phone with NoDo unlocked system, but with newest radio and "small" SPL halfbrick, nothing was happened (flashing did not start). But, I mean now, there can something similar "SPL5.xx - HSPL" conflict be occured also for "SPL5.xx - flashing SPL1.xx by RUU only - undefined Radio state". Slovak man HD7 was in totally undefined state from second hand, but I mean it will better for everybody to stop unbrick experiments (also with GoldCard) before full conflicts clarification. M.

Edit(17th December 2011): I have tried flashing DFT ROM OS Version 7740 (http://xdaforums.com/showthread.php?t=1350437) with full success on my phone.

Then way Halbrick --> force OEM Update --> "small" HalfBrick --> downgrading SPL by GoldCard (may be simplified without CID reading) --> Unbricked state --> apply RSPL/HSPL --> flash ROM is probably care independent of actual Radio version. But use carefully and on your own risc.

[Windows Phone 7 Development and Hacking] 5ft24:
not if you don't take out the screw with the VOID sticker on it, plus I tested it with the card not being swapped for a formatted one, and it works just fine. Just reboots 2 or 3 times more when it first starts loading than it did before.
[Windows Phone 7 Development and Hacking] Martin7Pro:
See post http://xdaforums.com/showthread.php?t=1195647#4 . I am not sure if any RSPL/HSPL from post http://xdaforums.com/showthread.php?t=1195647#1 supports your SPL, but, you will see it on second application screen in listbox. Do not continue, especially when 1st SPL number is different!

If no support, you can downgrade SPL first. For SPL-4.xx I have confirmed no downgrading brick (different from 5.xx - see my last posts). But, I prefer GC for 4.xx too instead of ROMUpdateUtility.

Or, you can wait for Cotulla confirmation/update, but it may be long time, he is very busy now.

Hi Guys

This is my first attempt at flashing my HD7

I'm on mango with an SPL-5.10.2250. Reading through the threads, am I right in thinking that I cannot flash the nextgen+ ROM without first downgrading the SPL and installing/launching HSPL/RSPL, and that if I just run the ROMUpdateUtility.exe without downgrading the SPL it will likely brick my HD7?

Sorry to be a bit 'thick' but i just need to be sure ;)

Regards

[Windows Phone 7 Development and Hacking] GoodDayToDie:
You're basically correct. I think running the RUU without installing HSPL just won't work - it will complain that the custom ROM isn't signed correctly (because we don't have Microsoft's private key, of course). Trying to install HSPL on a v5.x SPL will result in Bad Things, though.
[Windows Phone 7 Development and Hacking] Martin7Pro:
Yes, mostly right. But, I have one Fullbrick confirmation when using ROMUpdateUtility to SPL 5.xx downgrading. For any devices in combination of any ROM (cca 5% which I have answered) - flashing starts, it may to get success (more confirmations), but it may to get also Fullbrick probably. GC is better solution, but, I have also one Fullbrick confirmation from man used ROM flashing after GC SPL downgrading (but, he does not know sure, if he had full battery).
[Windows Phone 7 Development and Hacking] chromedome:
Thanks guys for your replies - really appreciated! Guess I'll have to wait for an update from DFT as I don't want to risk bricking. WP7 is a pretty cool OS anyway, but the better battery and possible signal increase from Nextgen+ ROM just got juicing a little ;)

[Windows Phone 7 Development and Hacking] Martin7Pro:
See my older posts. You have got "small" halfbrick. You can use GC or simplified GC for SPL flashing in USB Host Mode (hold Volume down + Photoshoot after restart, it is danger operation, but without warranty lossing if success). Or, if you have one from 4 supported devices, you can pay JTAG/XTC repair.

Ahoj Romane. The same answer as above (GC, but on your own risc). Or, you can also wait for Cotulla 3.2.xxxx HSPL version.
[Windows Phone 7 Development and Hacking] Nullstring:
no, I have not done anything yet. I just showed the SPL version because the available version from DFT_RSPL_WP7FG2_LAUNCH is 1.x so I did not continue HSPL'ng anymore because I thought there are a new versions.. The phone doesn't really have any problem and still running it's updated Mango OS. Update came from Zune software.

I saw some thread about downgrading from 5.x to 1.x, is that an option?

[Windows Phone 7 Development and Hacking] Martin7Pro:
Sorry, I could not compute from 1 to 4 :) It is very often picture, I must look better here next time. SPL downgrading from 5.xx is the same procedure as "small" halfbrick solution. Choose, what you like: JTAG(XTC)/GC. I mean GC (or "simplified" one, when you have WP7 and Windows PC machines only, see details in my older posts) is easiest way. If success, with Y-cable you will not loos warranty. But, if no success (cca 1%, usually by wires electrical connection or power mistake), you can get fullbrick.

---------- Post added at 09:17 PM ---------- Previous post was at 09:05 PM ----------

Yes, for 3.xx - ROMUpdateUtility is possible and probably safe, for newest SPL it is danger to try. OT: Have you also cca 400ms haltings sometime on this ROM as me? (post to PM or DFT thread)

I just spent the last 3 hours rigging up my cable and following these steps and unfortunately my HD7 or the card reader so much as make a flicker... could it be that I am going to have to try a gold card although I'm using a branded TMobile ROM for a Tmobile branded phone?
[Windows Phone 7 Development and Hacking] 5ft24:
double check the cable wiring. Does the phone go into loader mode? (white screen with blue writing).

Make sure to hold volume down, camera AND POWER until it is in loader mode, or it will just go to tri-color spl mode. And it all has to be connected and plugged in first. If the phone is powered on, hold power and power it off. As soon as the screen goes black, hold all 3 buttons down.
[Windows Phone 7 Development and Hacking] cdzo72:
Thanks for the suggestion 5ft24... Yeah I was up til past midnight last night rigging up another completely new cable and same results, the bootloader does nothing, I get the same screen pushing the Vol- and Camera button while powering on as I do by just pushing the Vol- while powering, the half bricked bootloader screen with the one line of message at the top.

What type of screen am I supposed to be seeing?
[Windows Phone 7 Development and Hacking] 5ft24:
You should see an all white screen with blue text.

make sure that before it starts powering itself on (which it does with power on the USB) that you hold the power button down along with vol- and camera... may try and click the camera button a few times as it boots while holding the other 2 down...
