[Q] EVO 3D stuck on splash screen reboot - read many Q&A - HTC EVO 3D

Greetings!
I've inherited a EVO 3D that has issues. I'm new at this, but had 3 other old HTCs. I read a lot that i could for the last 12 hours in various forums and made a few mistakes/discoveries. I tried a few but i think i am stuck and i couldnt see anything else that can help so here i am. groveling for help. My first post too!
The 3D when turned on shows the HTC with white background splash screen for maybe 30-45 secs and blanks out. then reboots again ad nauseaum. In short, the phone cant boot to Android.
when plugged into the usb, seems to heat up under the camera area but not the battery, it actually drained the battery (or so i think ) because i was able to boot it before, and after i left it plugged in for an hour, it was hot and will not charge (red light blinks) i found out later voltage was below 3.0v used my old raphael to charge the batt (that works) so i can continue working on the 3D.
- i found the hboot power+vol down and was able to get into fastboot usb.
- was able to unlock using htc method
- tried loading cwm 4.0.1.4 - says success but wont enter recovery mode - just same splash screen
- tried loading cwm 5 (latest) says success but wont enter recovery mode - same as above
- found out about the RUU method. flashed back stock recovery and locked again and using the PC86IMG.zip method in hboot and a sd card. new 2.08.651.3 stock RUU was loaded successfully. but alas, still stuck in reboot/splash page.
edit: i noticed it "bypassed" one of the TP. not sure what that meant. when i was installing the stock RUU.
i dont know about the S-on or off, cant see it from hboot. can i?
i dont know if this has been rooted but the previous owner said no. it was still locked until i unlocked it.
so now, when i try recovery or factory reset, it immediately reboots and show splash screen only ad nauseaum. ( i waited as much as 5 reboots )
Help please? let me know if u have any questions.
Thank You!
CK

Go get flash image gui from the market. Put your recovery of choice on your SD card and flash it via flash image gui. Hboot 1.5 recovery partition is marked as "read only" hence the s-on, which can be seen in bootloader. The way around it is to fastboot into your device and flash zips that way or flash kernels and recoveries via flash image gui app.

Thanks Jwolf1,
I did try both CWM 4 and latest CWM 5 that is 3D specific. but it just reboots immediately and cycles over and over again and wont go into recovery. But! I may be missing a step or two. I havent found a post yet or a faq where there are more detailed steps to do this. maybe you can point me to one thats EVO 3D specific?
I tried the link but unfortunately, all it shows is the domain name is for sale.

Thanks Jabawockee,

Thanks jwolf1
I went to the site but i dont see anything that could help my case.
do you have other suggestions?
it seems that everyone expects recovery to fire up after a fastboot boot or a pc836img.zip boot from sdcard. i just cant seem to get to that page
I was observing that everytime i run a fastboot flash recovery something, i see it being loaded, but i dont see it being "written" (the progress bar on the right hand side is just a blip. no color) but when i try a recovery.img that is with the stock rom i have. i do see color in the progress bar when writing. not sure if that means anything.
I'm trying to find out if i can wipe cache and dalvik without going into recovery (since i cant boot the phone properly) but so far, all indications is ... no.
also, is there a way to peek inside the phone to see if the partitions are corrupted?
Thank You.

OP: You have my big thanks for trying to find an answer by yourself BEFORE you ask for it. A simple rule that n00bs are constantly failing to comprehend.

new info...
I think i may have found the issue...
while trying over and over again, i notice i wasnt getting consistent responses to a certain command. in particular,
fastboot getvar all
on most cases, i get the following response on the cmd line
getvar:all FAILED (Status read failed (Too many links))
but once in a while i get
(bootloader) version : 0.5
(bootloader) version-bootloader: 1.50.0000
(bootloader) version-baseband: 0.97.10.0808
.
.
.
(bootloader) security: on
(bootloader) build-mode: SHIP
(bootloader) boot-mode: FASTBOOT
So i think the problem is, when i try writing to recovery, the message may say OKAY. but i am not sure that its being written in.
when i try a "fastboot erase recovery"
i always get "FAILED (Status read failed (Too many links)) "
another problem could be that the boot-mode is FASTBOOT
Is this the same as the one that we are suppose to turn off in the settings?
if yes, since i cant get in the phone settings. how do i turn it off?
if no, then it doesnt matter?
and is the security: on an issue? maybe why i cant erase recovery or load recovery ? i do noticed a difference in the screen on the phone when i load a "signed" recovery vs CWM and TWRP.
Anyone? help?
Thanks.

Is it correct to.say you have a Sprint Cdma 651.3 hboot 1.50 based Evo3D?
When u enter hboot/bootloader you should see either "s-on" or "s-off" near the top and either "locked, unlocked, or relocked".
I had a problem with that Ruu.zip file Mr.Esp posted, maybe a bad download. Find another link (i did) or.run the 651.5 based Ruu for the updated radio (i did).
Note: you have to relock before running the Ruu.

I don't know if.it will help you or not but I had some issues getting certain recovery files loaded & booting to them afterwards to flash files from. I have the details & step by step scenarios of what I did that may help if you are overlooking a step. See the ROM/recovery issues thread in my signature.

It sounds like the kernel/boot.img may not be correctly loaded after a ROM flash, but I'm not sure.

mpgrimm2,
Thanks for the help! Thanks for inspiration!
i ended up inadvertantly fixing the damn thing. it was a hardware issue but i dont know which one.
I got fed up of 4-5 nights of not sleeping and got myself another "broken" evo 3d.
It had a broken digitizer so i was going to perform the swap. as i disassembled the first 3vo. i had the mainboard out and i figure, why not test it? hooked it up to the usb and hand held a batter and lo and behold i saw "normal" recognition pattern by the pc!
I slowly assembled it again, testing it at each and every connection to see if everything is still the same or maybe some other component may be causing the issue, and i finally have a whole 3vo working! booting! now i can even fastboot boot cwm ! damn! no more boot loops!
i am not sure if its was me pressing on the mainboard and maybe a chip got a connection back or maybe just one of the cable has a loose connection but now its fully functional again. (i'm thinking more of the former than the latter)
reason why is because of the heating issue it has. i wont be surprised if the issue comes back or if others has the same issues.
so for others with the same symptoms, try disassembling it and pressing down on the part where it heats up. one of those with the heat shields (using only finger and thumb!) good luck!

My evo 3d is exactly the same problem. I have disassembled and reassembled it, also pressed down the part with heat shields, but no lucky to me:-(

I never have erased a recovery I have flashed over the old one... Seems to overwrite that part the recovery is stored...
Haven't had any issues doing it this way...

Subaochen,
Try plugging the mainboard while disassembled, just mainboard and battery. thats how i found out mine works. then you can slowly reassemble step by step. if yours doesnt connect normally during that time, check the board over. if you can identify which part overheats then you know where to press...
Good Luck!

reaper24,
I have tried "fastboot flash recovery any.img" multiple times without success, until i disassembled it and then, everything was just normal. could also be a dirty connection for me. altho when i run the RUU, it "seems" to work properly since i was able to upgrade to latest stock ROM.
I do have S-ON so i guess i would never be able to erase recovery nor boot.
hopefully everyone have the patience to troubleshoot their unit. i had to learn patience with mine.
boot loops are really the discouraging to say to least.
Sincerely,
CK

Thanks xdapro first!
I have tried again but not lucky:-(
Maybe my situation is not the hardware failure, just the wrong kernel or boot? When I accepted the OTA while the phone was rooted and after have a full reboot, the phone just stuck at the htc splash screen and boot loop.
I guest that, when I accepted OTA, the bootloader was updated to Hboot 1.5. But because the phone is rooted, kernel or boot partition is not updated by OTA, so the security signature is not the same between the new bootloader and the old kernel, so the boot loop.
I have tried RUU and all custom recoveries I can find, all failed, the recovery seemed installed ok, but can not boot into recovery. Also, I have tried fastboot boot recovery.img, just directly boot into the HTC splash screen and boot loop.
Anyone can give any hints? thanks a lot in advance!

Just a heads up, you have to "relock" the phone before flashing the Stock RUU's.
From "fastboot USB" Type: fastboot oem lock
It will erase the recovery in the process. I have had bad ruu downloads before. If the exe doesn't work, get the zip version.
