Help with endless reboot and no access to revocery. - EVO 4G Q&A, Help & Troubleshooting

First let me apologize for putting this in Android Development. I am just stuck and thought you guys were the only ones knowledgeable enough to possibly help.
My phone woke me up this morning because it somehow got into an endless rebooting cycle and I cannot for the life of me fix it. I do not have access to recovery, when I try to enter recovery it just goes back into the boot cycle.
I did a wipe from HBoot but it did not help. I also reflashed some various pc36img files, but they did not help at all. I was not able to find a similar situation on the board, since the solution for the other ones all included going into recovery. Any help would be greatly appreciated.

[Q] htc desire wont boot up

i am new to the forum and i am looking for some help i have a htc desire unbranded and it is stuck on the htc splash screen it is on hboot 0.93 and i have tried downgrading but it keeps coming up main version is older i can get into fast boot but not recovery i have been reading a lot of threads but cannot figure it all out as there is so much information i'm chasing my tail tail lol if anybody can help me i will be very grateful.
Why are you trying to downgrade? You could use an RUU as a quick fix but it will wipe everything. You haven't given any details of what you tried to do or are wanting to do.
i believe i have to downgrade to hboot 0.83 to get the phone to work but im not sure i have tried a lot of ruu's but cant seem to find the right one i'm very confused by it all to be honest i'm stuck as to what to do
It would also be helpful, if you used a little bit more correct grammer (putting punctuation between each sentence) as much as possible. Some of us, can't understand what you're talking about. This isn't FB or an sms
Also, it would help. if you said exactly what you did, and how you got into this situation. Ie; flashes, etc.
For example, are you rooted? Were you trying to flash a custom ROM?
htc stuck on boot up
Sorry i am not the greatest writer. I was on 2.1 and upgraded ota to 2.2.then the phone started resetting itself. before not booting altogether.i am currently on rom image 2.29.405 hboot 0.93 .and thats as far as i know.
htc stuck on boot up
The phone just hangs on the white htc screen.and wont go into recovery.
First of all, you have a desire. Before running any update, you need to create a Gold Card. It's not specific to "all" desires. But, better safe than sorry.

To boot into recovery the manual way, turn phone off.
Hold volume down, and press the power button.
This should boot to recovery.
If you get the Triangle, with exclamation mark,
press Vol Up + Power
This will bring you to another recovery menu where you can : Reboot , Flash from sd , Wipe Data/factory ,Wipe Cache
If you can recover the system, I highly suggest creating the Gold Card.
And one more note, if you decide to flash to a stock RUU, I highly recommend wiping all cache memories before flashing. Yeah, I know they will tell you that it's not necessary, but hey, I believe in overkill.
htc stuck on boot up
That's the thing it wont go into recovery, I can go into boot loader and fast boot but when i press up and power it goes back to the htc screen and hangs there again, i have tried a ruu which seemed to be successfull but it still hangs on the htc screen and will go no further.
If you can't get into any type of recovery, just how are you able to flash?
Bear with my stupidity here.
Without a menu system in any type of recovery, I am at a loss.
However, I have heard, that, some people put their phones in the freezer for several minutes. And that the phone would boot. Enogh where they col=uld goto recovery, and fix what they messed up.
Now, I would suspect it;s because the processor was overheating during boot. Probably because cache memories weren't wiped before flashing, and crap got all messed up.
Normally, I would never suggest this. And you do this at your own risk. So if it's messed up beyond repair, please, do not blame me,
htc stuck on boot up
I went into fastboot usb then ran the 2.29.405 ruu which completed successfully,i even extracted the pb99img.zip file and updated that way but still no luck,ill throw it in the freezer for 5 and give it a whirl, who knows might work. and thank you
The freezer thing, is a last ditch effort. And it is only a temporary thing. 15 minutes max. Maybe enough to allow you to clear caches and flash.
I have run out of expertise. So, I have nothing more to offer...

boot loop no safe mode

Hi
im really hoping someone could help....
my phone decided to yet again throw another tantrum and crashed out, i first of all lost bluetooth like last time, and it kept hanging.
I restored the rom but no avail.
Stupidly i decided to wipe everything in clockwork mod and now the phone just shows up the android splash screen flashes and then shines again.
ive tried going into safe mode (vol - and power) but the phone fails to launch it. all it does is vibrate then continue onto the android screen
am i up the creek?
thanks for your help

try the suggestions in this thread?
(simple search brought this up)
I'm curious, did you full wipe and then try to reboot without first flashing a rom? I've always wondered what would happen if you did that, not keen to try it myself

[Q] Phone stuck in a degrading boot loop

I have been an XDA lurker for years and have never had a need to post since everyone on here is so great about solving issues as they emerge. Anyway I have searched high and low for any answers to my problem with no success. My phone was rooted running a kit kat rom (Dirty Unicorns) when this issue occurred. A couple days ago I sent a mms and noticed my data was off so I turned it on via the power menu and my phone rebooted. Now this is something I have encountered with certain custom roms so I thought nothing of it. The phone went through the reboot process but then it rebooted again after about 3 minutes of normal operation. Since then the time to reboot has gotten worse until now it wont go past the Samsung boot screen. I have tried nandroid restores, cache/data wipes, and finally pushing stock roms via ODIN. None of these change the reboot behavior. Finally, as if everything else wasn't enough, I can no longer flash roms via any custom recovery. This to was something that also degraded over time. At first I was able to flash .zip files for the first few hours but eventually that to would also send my phone into a bootloop. I am clueless what to try next. Any help would be greatly appreciated. Thanks.

HELP stuck on bootloop nothing is working

My phone has been stuck on boot loop for hours. I don't even do any of the advanced things i've been reading about while trying to figure out what to do like root & mod etc. all i did was call and pay my bill, & then restart it and it's been stuck ever since. I've tried rebooting, factory resetting, wiping the cache. nothing is working. i currently don't have a way to put something on my sd card to fix it. I don't know what to do. i need help. preferably before it dies because i honestly don't think it'll charge.
Can someone please help me?? ):
hi, is it working now ?
