HTC TP2 bricked? Freezes at Start up!

Please help!
My HTC TP2 freezes at start up with the black screen and the Touch Pro2 Logo and some details in red at the bottom:
B 80
R 4.49.25.17
G 61.44tc.25.32U
D 1.86.67102
No USB connection can be established.
What happened:
1. Tried to update from original WM 6.1 to WM 6.5 by using the official HTC ROM update utility. Seems like USB connection broke during update and update freezed at 42%. Update utility process has stopped by itself (no process visible anymore in the Task Manager).
2. Restarted phone and multicolor screen appeared and stayed. After connecting with USB cable again "USB" appeared at the bottom. Started again the HTC ROM update utility which recognized the phone and started the update process again, but stopped at the beginning with an error message stating something like the ROM is broken.
3. Restarted again (by removing the battery and hit power button) and state reached like described above (HTC TP2 freezes at start up with the black screen and the Touch Pro2 Logo and some details in red at the bottom).
4. Performed a hard reset but did not help.
What can I do to bring the phone back to life?
So you can't or can get in the colored screen now? (the boatloader)
And it's kind of normal that their nothing happens after the tp2 + red information screen, this since their is no rom to startup.
EDIT
Is it possible to tell exactly what error you got?
EDIT
Try to hard reset your device, do you know how to do this?
If not this is how to do it:
To perform a hard reset
1. With the device turned off, press and hold the TALK/SEND, END and POWER buttons until you see this message on the screen.
"This operation will delete all your personal data, and reset all settings to manufacturer default. Press VolUp to restore manufacturer default, or press other keys to cancel."
2. Release the TALK/SEND, END and POWER buttons.
3. Press the VOLUME UP button to perform the hard reset, or press any other button to cancel the reset.

This is just what worked for me..
Had the same issue on my tp...
Hope it will work for you.
Did already the hard reset - but this did not help as nothing changed!
One further info: whenever I insert the battery the device automatically starts up - until it freezes again at the start up.
Can someone please help?
It's normal that the device starts up when the battery is plugged in...
But this is just what I know out of my own experience.
So sorry I can't help you farther.
EDIT
Did some research you might want to try to flash your phone by micro sd... (not for sure if it helps but by some people it did work)
Read the tread about flashing at the top of the rhodium section and you know how to do it.
Did another trial: downloaded and copied a RHODIMG.nbh to the micro sd card, inserted it again and pressed volume up at startup -> colored screen appears shortly, then switches to a white screen telling "Loading..." in blue font color, but nothing more.
Is there anybody out there who can help?
Do I need a specific RHODIMG.nbh to make this approach working? I didn't flash this device before, so it has been still in the original manufacturer's state.

suppose 2 press down volume not up after soft reset
This may help,
Try entering bootloader by switching off device then switch back on holding down the Vol down key.
If you can enter bootloader this way then you wil be able to flash from SD card following the instructions from here
http://forum.xda-developers.com/showthread.php?t=550540
if you want to flash the Official update from HTC you can extract the Nbh from the Exe file you downloaded from them, just use winzip, Zzip or Win RAR to extract the contents from the Exe you are looking for RUU_signed.nbh..follow the above thread instructions to change the name of the file to RHODIMG.nbh.
I DONT KNOW IF YOU NEED TO HARD SPL FOR THIS..Probably better to do it than not. Can Anyone Confirm???
i hope this helps
Device is up and running again !
Could enter bootloader mode and tried first to install again via the official HTC installer -> worked!
Thanks a lot for your support!
great news welldone Bro and welcome to the forum!!!

For future info, from what I have gathered you must hardSPl for all ROM flashes. If the ROM you flash is the stock ROM, you can also revert your SPL to stock. For any other ROM, you must leave your device hardSPL'd.
Hope I helped.
how were you able to connect the phone with the pc. i seem to have a similar problem but am finding it difficult to connect the phone to the pc. i have activesync installed but cannot connect to the phone

is it possible to connect to active sync in bootloader, cos my phone cannot even boot, it freezes up with a white screen and htc logo.
After entering bootloader you can flash either way,either by ruu package provided by your ROM's maker or running official ruu release or if you have the renamed file on the root of your sd card....I never use sd card flashing and have never had a failed flash...If in bootloader it will not connect with activesync,but device should be recognized by ruu.exe

Phone won't start up ?

Here's the thing , I unlocked my bootloader and rooted my phone a while back (probably using an already outdated software , if i remembered correctly it was 2.3.3 , but i knew i followed the instructions here
http://forum.xda-developers.com/showthread.php?t=1133650)
Today, my phone asked if I wanted to update the software (like an automated software update) and i could choose to update or not and i chose yes but now , my phone won't start up for like 3 hours already . I tried turning it on but it won't turn on , i tried charging it but there isn't any lights which was supposed to be there .
So I decided to google it and i followed the instructions here
http://talk.sonyericsson.com/thread/26720
but after installing both , choosing my phone , followin the instructions on update service , it gets stuck on "it contains a modified software that cannot be updated" so decided to come back here to ask you guys what I should do .
Right now , all I want to do is for my phone to start up again , any ideas ?
edit : right now , i took out the battery , and put it back in . This time when I tried to turn it on , the vibrate is there which wasn't there initially and theres 1 flash of the green light on the side of the phone .
and also , i think its recognized by the computer because i can hear the sound notification (the same sound when you plug a USB into a computer) which wasn't there before I did the update service thingy .
edit 2 : it won't go into safemode either when i tried clicked the right and left buttons below the display (the menu and back button) and the power button after that . yes i tried reinserting the battery .
edit 3 : I'm not sure if this'll help but my phone is recognized as SEMC flash device (i checked on device manager) and theres a green colour non flashing light when i plug my phone into the pc .

OMG
Thanks
Sorry for not searching , I tried looking for Xperia arc won't load up / start up but it didn't give me this thread .
Thanks again
edit : i thanked you too

When I switch it on, it shows the SE logo and does nothing else.. I tried to enter the safemode menu (holding left and right keys when switching on, or volume down key and home key when turning on) but nothing works!!! I'm like desperate now so any help would be really appreciated!

Unlock the bootloader and flash cwm recovery. There are guides and tutorials in the development section of this forum, from recovery you can wipe data

phone backup and fix

Hi! if you want to really help me please read till the end because the problem is in stages and i want you to
have all the info! :angel:
I have a LG g3 (LGD855..) and yesterday it suddenly crushed and didn't come back - i pulled out the battery and put it in again and the it came back with a weird error:
DemiGod Crash Handler : Kernel Crash! :
Press key to choose Dload Mode/Reboot
1)Volume Up: Dload Mode.
2) Volume Down: Reboot.
etc'
Of course it didn't got into dload mode. I did some digging and found that is fatal error of the device and nothing can be done but try hard reset - but then I tried something else i read that is to pull both power b and v down button at same time when starting and get into safe mode - i tryed that - it didn't got to safe mode but it booted correctly!!! its alive!! - NOT FOR LONG. I managed to backup about 50% of my files and then it crushed again to the same kernel error. This morning I pulled out the battery and put it back after an hour and it came to a situation where the LED is in like greenish and blue light fading and the LG life's good (sure..) screen is showing - stuck like that and every few min changing the animation but no more than that. I managed to get the message "device" on adb so I figure maybe I can pull some files out of it, or maybe push a recovery like twrp and try to do something from there.. but i still want my 50% data left there so factory reset is really the last resort. Please help me.. what is my best option?
is it possible to pull files to my comp like that?
is it possible to push the recovery with adb?
and what kind of recovery do i need?
and will it wipe out all my data?
My device is rooted and i have no recovery or SD card. Thank you!!!
*update: adb reboot bootloader - does nothing but reset and get back to the LG life sucks screen...

Help -- phone won't boot and I need to get photos off

My daughter has been using this phone, but never backed her photos up. Now it won't boot and she is worried they are lost forever. I've been trying to help, but only seem to make things worse.
1. She never enabled USB debugging, or rooted it
2. She could not tell me whether she had allowed the OTA upgrades.
3. It got into a reboot loop a few days ago. It would start to boot, then say it was optimising a random number of apps (anything between 90 and 158) and then start over. Wileyfox tech support told me that this was due to an incompatibility between Cyanogen and the latest Facebook Update.
4. They sent me a link to the FOTA files with instructions how to progressively upgrade to Android 7 (TOS111B)
5. They couldn't tell me how to determine whether it was running CM12 or CM13 (I now realise that I could have looked at the log files in the recovery partition)
6. I therefore assumed that it was running CM12. I used their instructions to go into recovery and manually update from SD card to ZNH0EAS2NH from there to ZNH2KAS7EB and then to TOS111B
7. Fatally I did not reboot between updates. At the end I had the Wileyfox splash screen black on white, and then got an animation with it red on white. It then got stuck.
8. I then tried using fastboot to go back to the original version of the OS so I could start over. I found the fastboot image and I flashed the boot and system partitions.
9. Now on boot it either gets stuck on the black on white boot screen, or it displays it for a second and then turns off.
Can anyone help me? - I think my daughter will have a nervous breakdown if I don't find a way of recovering her photos. Recovering the photos is more important than unbricking the phone.

Since posting this I have had a partial success. A more complete set of fastboot flashing using the TOS111B fastboot images has got me to a phone that boots. Many of the apps work. However...
a) I get an "unfortunately the process com.android.phone has stopped" appearing almost as fast as I can close the app making it very difficult to get anything off the phone. However, I did manage to set up a google sync to upload the photos.
b) my daughter now tells me that her SMS's are vital.... and the messaging app says " getting message" then closes down
c) I cannot enable developer setting to enable usb debug mode. I can get into the phone status page under settings. Repeated tapping on the android version brings up the nougat splash screen, but the 7 taps (or 700 for that matter) on build number does nothing whatsoever.
Does anyone have any ideas how to recover to a fully working system without doing a factory reset?
I suspect that the sms database would have gone when the cache was cleared. Can anyone confirm that to be the case before I spend any more time trying to recover them?
Hi Jerry ,
Exactly the same problem here. Could you tell me where you've found the TOS111B fastboot images?
Thx!
Have you tried booting into safe mode?
I think you do that by pressing and holding the volume down down button during reboot.
If you can manage that you may be able to dissable the apps that are causing the crash.
