[Q] Broken Bootloader

Hi, I think my phone just broke.
It's a HTC Desire Z.
Today I tried flshing a new radio image, but it didn't work , got the write failed message, from within phone os (virtuous froyo 1.0.2)
Got hboot 0.85.xxxx.
This was at work and since I had no compatible USB cable I thought I'd wait until I got home.
Well at home i selected boot to bootloader from holding the power button, the phone shutdown and that's it.
Now only lifesigns are the orange charge led.
When pulling the battery and inserting it, connectiong the usb cable the light comes on, pulling the cable it turns of.
When cable connected and pressing vol down + power, nothing happens, pulling the cable leaves the charge light still on.
Trying vol down + power without the cable does aboslutely nothing.
Do, does anyone have any clue what I can do ?
The phone worked flawlessly until the reboot point.
Iknow the first desire had some special key combination to get into some blue-led mode, haven't found anything on this so far.
it does not show up in devices in computer management either.
HELP!!!!!!!!!!!
P.S. I found the vol up + power it shows up as Qualomm CDMA Technologies MSM in device management.

There must be a way to recover this type of brick, to dd a new hboot image.
Lets face it, the hboot image was flashed to a brand new HW at some point, the Q will therefor be, how do they do it, and how can we all do it?
Research continues.....

Ok, does anyone know how to fix a broken bootloader on the Desire Z ?
I figured out that the bootloader is broken, this because I mixed up radio and hboot image yesterday and tried to write the radio image to hboot partition, this is why I got a message telling me write error because of space issues.
Now I have my old Desire Bravo, wich is working better than all desire bravos here at work
But I want my Z back in bizniz.

have you got insurance??
u could drop it down the stairs at your workplace... claim on insurance... make sure its truely broke though...
just a stupid thought
if warrenty wont replace then insurance most probabally will... if its so broken you cant even turn it on to get the led. lol
either way mate i really hope you get it sorted soon best of luck!

You have brick your phone. bootloader is broken no fix for it. Sorry.
If you do not have warranty call htc Norway and say that you try to update your Software WITH HTC SYNC. They are very customer friendly there.

I've been talking to mcare and deltaservice, they seems to be unable to help me since the bootloader is broken, I know this issue can be worked out with JTAG on the old desire, just have to wait for JTAG update on the Z, then I'll be up and running again, btw, I'm getting a new phone AND got to keep the old one
Ohhh, yeah.
BOYAAAAHHH!
I still wonder what the volume up + power key combo is good for.
When the phone is started in this mode, it shows, as mentioned earlier, as a Qualcomm CDMA Technologies MSM device in device manager on my puter, diagnostics mode ? possible way to get write access to internal memory, like say.... /dev/block/mmcblk0p18 so we can repair the bootloader without any advanced tear down of the phone and fancy equipment ?
If ANYONE have a clue on this feel free to share it with everyone else that has a Desire z/Vision. Thank you.

[Q] Can't boot HTC Wildfire S

A friend of mine, gave me today an HTC Wildfire S, who found laying in the street. Problem is that i can't boot it, even in bootloader (Vol Down + Power) if i try to boot into bootloader only a tiny red light appears on one sensor, and if i try to boot into android, it appears to boot but nothing appears on the screen.
Any Advice?

Is it detected when connected to a PC?

I thought about a lot of things as your post didn't have a lot of info:
1- you aren't aware of battery level, leave it for an hour or two connected to the computer to recharge the battery.
2- do you have hTC Sync 3.0 ? You have to have it so the computer can recognize the phone.
3- putting it to the bootloader mode and nothing appearing on the screen makes me a bit worried.
Let us know how things will go !!!

1 - Full Charged, at least charging light now is green (was orange before, like in other HTC's)
2 - Yes, i also have ADB drivers installed, but nothing appears with cmd "adb devices"
3 - I don't know if is rooted, or has USB debugging on.

Best thing to do is use xtc clip, create gold card etc and flash the Rom.

I've found the problem. Looks like screen backlight is working fine, but no info is coming to it. I know because when i press touch buttons they vibrate, and vol buttons sounds when i press. So, do you know where can i get a cheap LCD screen replacement in EU?
Thx in advance

How about trying to find out who is its real owner and return it to him or her?
Can you feel confortable using something you know it is not yours?

tottaly agreed. just think when you lost yourself your HH..

It would be a nice idea, but my friend found it without SIM or microSD and can't get it work, so if you have any idea about how to find the owner, I'm listening.

After getting an LCD replacement and booting it up properly you could check the accounts & sync settings to see the Google account they used with the phone. That way you can maybe contact them. Contacts are also saved on phone memory, so you could have a look there.
If you did find the owner then you could charge him a little extra for finding and repairing it.

I have the exact same problem with my HTC Wildfire S.
So what did you do with that phone?

[Q]Bricked htc trophy when installing Mango !!

So here's the story ; I bought the phone worked normal , nodo installed , security update installed , i then register a developer account , installed mango beta 1 , then beta 2 , after that the leaked rtm mango, random restarts.I thought its normal since the drivers aren't updated for mango. Reverted back to nodo today so i can get the mango through official channel with the normal driver. I keep checking no mango , i then tried a disconnect trick a discovered on the forums. version 7401 was installed and then random restarts much often than usual. After disconnecting the phone on step 9 and removing battery couple of times phone booted up and stayed on. After that the Zune prompted me to install Mango. After doing everything zune said Step 8 of 9 Restarting your phone. Phone was stucked on HTC logo disconnected phone removed battery like i did before... but now i can't start it up , no logo no nothing , Power + Volume down does nothing... warranty is still valid though , should i send it for repair? Thanks for any reply

If it's a Verizon trophy, look at the leaked HTC roms, they are the same thing.... (version for version they are exactly the same as you get from the Zune download).
Flash that rom and you'll be on Mango final with all the features that you want.

Check in the HTC Trophy area on this site... there is a bunch of roms, find a NODO rom and put your phone in boot flash, flash it, it should get you back to a working phone.
I know about the CDMA version of the phone and you have the GSM, so I can't help you with the exact rom you need but, I am sure you can find it.

If it won't boot up, and no trick to make it boot up works, then get it swapped. No reason to ask here when no one here works for HTC or whoever you bought the phone through.
From the random reboots you mention, you might have had a semi defective unit from the start as it shouldn't be rebooting that much on you if at all.

Exactly the same problem here. Going to contact htc sav :/ to fix that.

This was the issue; how long did you wait?
I remember when I last upgraded, the phone ages to reboot. You have to be patient!

Same problem here.
HTC Trophy. Was on NoDo (7392 or something like that) and never installed any pre-release Mango. Phone is not developer unlocked or unbranded (it's VF).
Did the disconnect trick last night to get the update. It installs 2 updates and the first went fine but the second (which I think was the HTC firmware update) took quite a long time and eventually got to step 8 of 9 (restarting phone) but stayed there for at least an hour with the HTC logo on screen.
I left it and went to sleep. Woke up this morning with Zune still saying step 8 of 9 and phone blank.
Phone is completely dead. Whether it's unplugged, connected to PC or connected to the charger it won't power on. It doesn't even show the red or green power light. Camera + Vol Up + Power also does nothing. Checked battery with multi-meter and it has power so it's not a charging issue.
It looks almost like a hardware failure (by the fact that there's no activity at all). Maybe the firmware update taking so long overheated something in the phone.

I have the similar problem while updating to Mango. But my current state is a little bit different (may be a bit better then other people). It is stuck in the HTC logo screen.
I have can get into bootloader, but the official bootloader doesn't allow me to do anything.

dears
i have same problem with my trophy
first step: if your trophy can't enter boot mode you have to go to profisnal tool like Riff Box or ORT Box thay used JTAC method and you have to open your phone to connect JTAC cable then repir Boot area and no way to repir this area without this solution
after repir now you can enter boot mode
sec step : flash your phone with Correct flash files
but my Q is what kind of flash can be correct i try many but still hang on HTC logo
we need some one give us correct info about :
all flash file Brand or unbranded and what the true one
are we need to repir RSPL Or HSPL

These sound like factory faults to me. I've been playing around with different ROMs ever since I got my phone,no problem. The only things I wish I had were usb storage and tethering, I wish they were possible without going through an encyclopaedia of instructions,that's a sure way to brickville.

Leave the phone to wall charger for at least 30 min and then it will boot up

I tried that a few times. In fact I left it plugged into the wall charger overnight. Still nothing.
I ended up getting a replacement phone from my carrier. Interestingly the battery was completely flat when I put it into the replacement phone. They only replace the main shell (refurb), not battery, charger cable or back cover. I had to leave it plugged into the charger for a minute before it turned on.
The difference between the dead phone and the replacement is that the replacement would charge (immediately showed red light when plugged in) but the bricked phone didn't charge or even seem to recognise that a charger was connected.
I do wonder what would have happened if I had charged the battery some other way and then put it back into the phone. I'll never know because the courier took my phone away when they dropped of the replacement.
The worst part was being without my phone for 4 days (over a weekend) and then having to reconfigure and reinstall everything on the new phone (because stupid Zune does not have any way to restore a backup to a different phone). I think the only thing I really lost was my text messages in the end.

Well I've had my phone for 7 months without any issues, including the couple of updates we've had since February. I think what caused the problem here was that the Mango update included firmware updates from the manufacturers. It actually applies one update, restarts the phone and then applies a second update which is the HTC Firmware update. That's the one that doesn't complete properly. Looking around online there seems to be a few HTC (Trophy and HD7) users experiencing the same thing.
I applied the Mango update to my replacement phone (also a Trophy 7) without any problems so maybe it only affects certain Trophy phones.
And I agree with you on the tethering - that's one of the main features I seriously miss from my previous phone!

Then a lot of people must have the same problem with their PC or USB port (including 3 people on this thread alone). I can't post links yet but if you do a Google search for "mango bricked HTC windows phone" there are quite a few links, each with multiple people having the exact same problem (completely dead phone, no power or lights at all). I wouldn't call it "widespread" yet but there's definitely an issue affecting certain HTC phones when updating to Mango.
I had done previous updates on that phone (using the same PC, cable, etc) without issues and the first part of this update worked fine (including the restart). Replacement phone (exact same model) updated fine on the same PC with same cable (including the HTC Firmware update).

Bricked? APX mode?

I was given a HOX international tegra 3 by a friend to fix but i am afraid i am hitting a wall. He upgraded to the galaxy s3 and is trying to sell this off. I don't think he tried rooting, unlocking the bootloader, flashing anything. He stated that it would force close while trying to open Settings.app and everything started force closing when he inserted his SIM. He gave it to me because i was into flashing nexus one roms and kernels when i had a nexus one.
The phone doesn't seem to power on or show any signs of life on the phone itself. If i plug it into a windows machine, it recognizes it as "APX" but no driver is found or installed. I have searched around and neither ADB, Fastboot or nvflash recognize the device. I tried installing various drivers to no avail. I have pointed it to "android debugging bridge" and "NVidia USB Bootrecovery driver for mobile devices". ADB, fastboot and nvflash still do not recognize the device. It is also not listed in Device manager. Universal Naked beta driver also did not do anything. Can anyone point me in the right direction? I have done some brief reading on the S-OFF thread and it seems like you guys needed a device in APX mode for further progression? Maybe we can help eachother out.
TIA

Message Xmoo about the APX mode he's in the S-off thread should have some ideas. As to getting it to boot i'm assuming you've tried holding power for ten seconds?

i would suggest calling yor friend over,
tying him to a chair and beating him until he remembers how he got it into APX,
ppl would kill for that device in APX.

Careful, if you achieve to boot it, you may never be able to get in apx mode again. First talk to some experienced people in s-off thread to see what we can squeeze out from apx mode.
Sent from my HTC One X using xda app-developers app

tried every single power + volume combination possible. Everything leads to APX mode. It is like a 4 second wait with power and volume down. if its just power it takes like 15 seconds for the pc to recognize. I msged xmoo and am awaiting his reply.

Yes get over and talk with the team who are working to fully unlock this phone as they need apx mode and are dieing to have this mode one of them may even buy it from your friend in its current state as the crackers of this device are dieing to get this mode turned on on other devices if it's going to lead to an fully unlocked hox I sure am dreaming of the day this happens as I'm sure others are too so try talk with one of the guys over on other threads ask to see if anyone of them would like to buy it instead
atm do not I mean do not try to get the phone to boot normally until you have an answer of someone apx mode is needed and no one can get the hox in this mode

It would appear that the device defaults to apx mode when it is bricked. The fact that it won't even boot to hboot indicates this

In the bottom right of the taskbar, there is an icon that's normally used to safely eject a USB device. The only thing listed is APX. If i unplug the phone, the icon for apx disappears and vice versa.

I think I know why you can't get nvflash to talk to it. Chances are you are probably using a version designed for Tegra 2. There is a Tegra 3 version floating around but I'm sure it was a Linux version so you'd need Linux to use it. I'm sure I had a link but I can't find it. Also you might need the secure boot key (sbk) to flash anything but even just getting nvflash to do a --sync is a start.

I'll just copy-past myself:
Drivers etc. should be provided by this package: http://developer.nvidia.com/tegra-android-os-images (download here from list: http://developer.nvidia.com/tegra-resources).
Can download Linux,Mac,Win versions, all including drivers, nvflash and other stuff (bootloader, recovery.img, ...)

Hi,
Thank you for PM'ing me.
The phone gets noticed as APX, which is good. You need the Tegra3 Nvidia drivers. The problem is that you need to correct address in Nvflash. Cause if you talk with the wrong address, you could brick your phone. Since your friend kept it off for couple of weeks, I think that is the way it got into APX mode.
On old WM devices, when the battery drained and device had no power for a long time. The device would HardReset itself on the next power cycle it got. Maybe this is the same thing with the HOX. Battery is to empty, so it can't boot. Anyone who is willing to try the same thing? I use mine HOX everyday, so Can't leave mine powerless

Hehe, that was my first attempt after I read about APX on other devices that mentioned taking out the battery first. I let battery run out, booted few times into hboot etc until it didn't turn on anymore. Anyway, didn't work, as soon as I plugged in a USB cable, the phone had juice again and booted normally :/
If I remember correctly, there were also a few users who opened their HOX (think for wifi fix) and tried with disconnected battery -> no success

Yes but there is a difference. When emptying battery and directly plug it in. I would say empty battery in couple of days and then leave it for couple of weeks. Just like this story.

As I said, I didn't directly plug it in, but loaded hboot few times to drain the rest of the juice out. Then waited a few hours. Empty is empty, whether for 1 hour or 1 week.
Anyway, I gave up that attempt as I read about the guys who tried with disconnected battery. Can't get "emptier" than that ^^

Actually I don't, as far as I know there are no volatile memory in mobile phones ([edit]no crucial ones at least...I know i.e. RAM is volatile[/edit]), hence you don't need a battery to keep it alive, you just need one to run it.
Anyway, I'd be glad to be proven wrong ^^ Though it might be tough for some people, if they had to lay off their phones for weeks ^^

HTC 10 Will not Boot/Power-up

My new HTC 10 (bought from HTC UK) is completely dead it seems. I've not tried to unlock or anything and it's a standard HTC supplied model.
The phone had just powered off completely via black screen with no input from me whilst inserting the phone into a car holder. Possibly the side buttons were pressed but in any case it powered off via a screen with small text at the bottom 1/3 of the screen. I didn't get a chance to see the text.
Now it seems that no combination (that I have tried) of button presses will power-up the device - not even boot to recovery (volume-down and power button). If I do attempt to boot to recovery then the 2 capacitive buttons either side of the home button flash on then off about 2 times per second. When plugged into the supplied HTC charger the charge light does not show!
I am about to call HTC UK - I have had it less than one week. Any advice would be most welcome as my brand new HTC 10 has failed on me .

Plug the phone to a wall socket and keep the power button pressed until the buttons stop blinking (10-15 seconds maybe?). Phone should vibrate and boot again.

:good: :victory: - Thank you. That did the trick and it's now booted up again and all looks so far OK.
Have you any idea what may have happened and caused it to go to this state where it would not (normally) power-up? Just keen to know what might have happened and more about this situation? Could I have a fault? I ask because I contacted HTC and they may replace the phone as it was logged as DoA.
Many thanks.

I don't think anything serious happened. The phone was just frozen. It wasn't turned off. You just needed a cold reboot and that's it. Hard to say why it froze though. I'm no hardware expert .
If you feel like that, you could try replacing it, but in my opinion the device is okay.

The phone is still working fine so I'll be keeping. I'm very impressed with this phone, but miss a few of the HTC apps such as the Gallery.

You can always download the HTC apps from the Play Store.

Most of the legacy apps (gallery, music, sense input etc) all show up as incompatible when I check the store for them. Apk mirror on the other hand has them all for download.
