[Q] Stuck in HTC startup screen while booting - HTC EVO 3D

Well, I have to ask for help right here because Goole/Yahoo/Wiki DIDN'T help. Although it's a bit long but please read it
Here's my problem:
At the last time that my phone is still being functional, I was playing the game "Contract Killer" and "Facebook", "Internet" were running in the background.
Suddenly, it shut off with showing "power off...(Sth like that). This is obviously a normal situation when the battery is out of power. I took it to charge as usual and went to sleep.
Next day, I waked up and tried to boot up my HTC EVO 3D...
First time: Stuck in the startup screen without playing the HTC opening sound track( The phone used to be in Silent Mode)
Second time: I pulled out the battery and put it back and boot again. Still stuck in the startup screen but this time it play the HTC opening sound track...
I've got a lot data in the internal memory and I've never BACKUP before.....
Is there anyway that can boot up my phone without losing the data???
Oh...my phone has never been rooted.

Anyone know the problem??? (

I dunno, kinda sounds like a Hard Reset/Factory Reset is in order. Did you take the battery out for a while and then try to reboot?

There's no way unless u can take to service provider an have them extract it

i had that kind of a problem once but i was on a CUSTOM ROM so i'm not sure it will work for you and I'M NOT SAYING this method is THE SAFEST.
so 1st thing i did was.. i panic'd... 2nd, i started googling and when all the signs pointed me to a boot up problem i opened the zipped rom, i extracted the boot.img, connected the phone to the pc in fastboot mode and flashed the boot image. after that it started with no problems, all my data was there. what do anyone else suggest? would it be okay to flash boot.img (stock one) on a stock rom?

I would suggest the following:
If rooted with custom recovery:
1. Pull out the battery
2. Replace the battery, and access recovery and do nandroid backup, you will only need the user data.
3. wipe, wipe, wipe
4. install the ROM you had and let it boot
5. reboot in to recovery and restore you DATA ONLY
If not rooted:
1. Install custom recovery
2. go to rooted instructions
IF this doesn't work you can get the .img files from the forums of the ROM you had or stock if that was what you had and only install the boot.img and system.img and try to see if you get the phone to boot with your data in there.
let me know if anything helps.
PS. There is a great risk that you won't be able to recovery your apps data but lets try and hope for the best.

This sounds like a battery, cable, or AC adapter problem to me. You can get a cheap replacement battery on eBay for a few bucks and see how that works out. Also try different wall pieces, micro USB cables, and power outlets.
If none of that has worked, then you more than likely have a corrupted boot image. You can mount the EMMC (internal flash storage) onto a Linux distribution (like Ubuntu or Fedora) via usb and copy your data to a safe place like a flash drive or HDD. Then do an RUU (there are tutorials on this in the development thread) to restore the phone to stock, then of course pull whatever is needed from the data you saved.
Now if absolutely none of this has worked at all, you have malfunctioning hardware. Your only option at this point is to go to a Sprint store to have your data transferred over to a new replacement phone.
Hope this helped mate.

First of all, thanks for helping~ I would like to know that will my data lose if install the custom recovery? Seems like a huge risk...
Besides, I am a little confused about using the .img to boot my phone.......

Well if you can somehow get ADB access to your phone you can try to backup the following file:
/data/data/com.android.providers.telephony/databases/mmssms.db
This is there database that contains all your messages (SMS / MMS).
Flashing the boot.img file is easy, if you have the phone in fastboot (and it indicates the usb connection on the phone too) then you can just flash this way:
fastboot flash boot [location of boot.img]\boot.img
You will not loose any personal data, there that the partition affected by the boot.img is not the same as the one affected by /data. This also apply to the recovery section of the phone, in case you want to load a custom recovery:
fastboot flash recovery [location of recovery.img]\recovery.img
Hope this helps, if you need any more help let us know.

If you remove the battery off your phone and then you reinsert it back, press PWR+Vol UP to access the bootloader.
While in the Bootloader access fastboot and ensure to have the USB connected. from there, you can run any fastboot command you need, like loading custom recoveries or anything else.

---

WOW! I am approaching the target. To be clear, fastboot command stands for using ADB access?
AND:"While in the Bootloader access fastboot and ensure to have the USB connected. from there, you can run any fastboot command you need, like loading custom recoveries or anything else." means my phone can connect the computer by using "press PWR+Vol UP to access the bootloader"??? The bloody bootoader??
I am sure i'm almost there!!!!! THANKSSWSSSS

Fastboot is a different command center from it counterpart adb. From fastboot you use only commands related to the flashing img files and more.
Just use fastboot /? From the command prompt to see a quick help of all what fastboot can do for you, but the main thing you'll need from this command is the ability yo flash a new boot, and maybe system image to get your phone back up and running.
