Stuck on boot screen. - EVO 4G Q&A, Help & Troubleshooting

Went into recovery and wiped data, cache, dalvik then went to install Fresh 3.4.0.1. It was done installing and I gave it a reboot. At first I thought it was just the first time installing a rom that was making it take forever to boot up, but I fell asleep and just woke up, and that definitely wasn't the problem. It's still on the boot screen with the white background and black htc EVO 4G. I haven't been able to get into bootloader so far.
Any ideas?

I had a similar problem once. I would just get stuck at the splash screen no matter if i tried going into recovery or just normally booting up. What fixed it for me was to just take the battery out and leave it out for 5 minutes. Try putting it back in, booting into bootloader, then into recovery. From there try wiping everything and then installing Fresh again.
Also, make sure you are using Amon_RA recovery, as it correctly wipes everything.

yea try that what he said. take the battery n try it one more time n see if that works

[Q] Unbreakable Boot Loop?

Flashed Myn's R4, and then flashed Warmlines boot animation. Now stuck in Warmlines boot loop. Power/Vol+ doesn't get me into Clockwork Mod, and ADB cannot detect my device. The only way to stop the reboot cycle is to remove the battery. I have searched the forums and Google using the terms Evo 4G and Boot Loop, but haven't found a solution yet. Suggestions?
*Power/Vol- seems to be the right path to take. Please disregard this post until I do something else idiotic.

Your phone didn't like the boot animation eh. Pull the battery out. Let it sit out for a couple minutes. Put it back in. Hold Power and VolDown simultaneously until it loads up the bootloader, then release. Wait for it to scan the sd card, youll see some stuff scroll down the screen real quick. Then select recovey. Once you're in recovery, wipe everything 2 or 3 times (data, cache, davlik cache) Now you can either restore a nandroid backup if you have one or reflash Myn's RLS4. That should be successful, then reboot. I guess you could try reflashing the ROM without wiping data, but I would suspect that to still leave you in a bootloop, but maybe not. It would be worth a try to reflash the ROM without wiping data, and see if it boots and if it runs okay. Otherwise wipe data.

Having issues with Roms

Hey folk,
My buddy & I both have EVO 4G's, I rooted mine yesterday, downloaded rom manager did a backup and than downloaded a rom and everything went smooth no problems.
Now today I rooted by friends phone the same way I did mine, when It came to doing a backup or downloading a rom, every time it goes to reboot after the rom is downloaded or you do a backup, it will reboot and than all you see is the white screen and it showing the evo 4G logo.
I don't know what I did wrong? the root went successful and everything else is fine.
Any help folks thanks.
How long is it staying on the splash screen? Sometimes it can take a few minutes.
Is it stuck on the splash screen or can you get it up & running?

It was stuck on the splash screen for about 15 min or so than the battery died.

It stays stuck on the flash screen it won't move, last it was running for 15 min on the splash screen and than the battery died, so I plugged it in to the charger and powered it up and it was still the stock rom but still was rooted.

First thing: don't try to flash anything with a battery lower than 35%. It might be okay at levels lower than 35%, but it's better to be safe. You don't want to be flashing something after a wipe & the phone shut off.
Second: for some reason after rooting my phone, it takes a lot longer to reboot than it used to. This isn't something that always happens but it does some times. The first couple times it would even get stuck on the splash screen & I'd eventually pull the battery. I found that after I switched to amon ra recovery it stopped happening. You could try switching recoveries, but if you do rom manager won't function anymore & you'll have to do everything manually. It's not difficult.
Try again, this time with a full battery, and see what happens. Make sure cwm says that the flash was successful. If it takes a really long time to reboot, pull the battery & power it on normally. Sometimes it takes a while after wiping/flashing because it has to rebuild cache and/or load the rom for the first time, but it shouldn't take 15 minutes.

Every said was correct. But I'd like to add, that its possible that it didn't wipe fully. The screen should never hang on the splash for 15 minutes...five is normal, and sometimes happens after flashing. But like plainjane said, try another wipe. Also, flashing under 35%, it'll flash, but if your phone dies midway, expect to have a fancy paper weight.

Thanks Guys I will give it another try, but I would also like to men-son nothing gets flashed, the phone reboots - black screen than white screen and thats all.
When I did the same thing to my EVO the white screen stayed for about 40 secs and than started flashing.
I will try to remove rom manager and reinstall it.
So I am still having trouble with my friends EVO, it stays on the splash screen and won't change it lasted for an hour and than I pulled the battery.
Nothing happen to phone.
When I try to unrevoke it, it asks me if my version is new and reboots.
Even when I try to go to clockwork it gets stuck on the splash screen.
What am I doing wrong?
does anyone not have an answer for this?

I'm not sure this will help you, but if it were me, I would download unrevoked's s-on zip and flash that. Then get the PC36IMG.zip for the Stock unrooted 3.70 OTA and install that so you will be completely back to stock and unrooted.
Then try to root again. Also, try Amon Ra since clockwork was giving you trouble.

Tried to do the recovery and same issue I can not get into clockworks so I am basically stuck, If I goto recovery it will just get stuck at the white splash screen.
I am really lost at what to do now

Can you boot into your ROM at all?
^^^^^
No not at all.
If I power down than press volume down and power it will take me to the screen where I can goto to recovery but when I select it and try to go to recovery it will reboot and show the white splash screen that says EVO 4G and thats it, it will just stay there.
If I try to download a ROM or do a Backup and when it reboots to the same white splash screen it will just stay stuck there.
It looks to me the phone is partially rooted cause wireless tether, superusers, rom manager works but when I tried to download titanium so I can do the unroot and wipe the data clean titanium won't work.
At this point I have read a-lot of other posts and tried many other things but they all require me to go into clockworks which I can't. I even tried another method I seen on Youtube but I can't find unrevoked on my EVO anywhere.
I mean can you boot your phone up normally, and from the looks of it you can. You just need to reflash your recovery. Boot your phone up, go into ROM Manager and hit flash clockwork. After doing that, choose the flash alternate recovery option to flash Amon Ra and then do all your ROM flashing through recovery and not through ROM manager from here on out.

[Q] help please. possibly corrupted efs?

ok so heres what happened. this morning my phone started behaving weirdly. then it restarted and got stuck in a boot loop. I was running the newest aokp release. after the boot loop i restarted to recovery, i was using the team win one. i wiped cache and dalvik and restarted...still only to boot loop. next i tried factory wiping and reinstalling rom. still same thing, only then i couldnt clear the cache. if i tried it would just reboot.
on lunch break i figured id just odin back to stock. after playing with it a few times i got it to flash the stock back. after it rebooted the first time it went into recovery to clear the caches like it should but there was a red message saying cant locate efs or something. there was about 4 lines in red saying pretty much the same thing. and it said manual mode at the bottom.
ive tried wiping caches and restarting a number of times. I fallowed both the guides from the development section and from the general section. so i currently have the stock ics odined on the phone. it will boot to the rom and start. made it through the upgrading android part then once it gets to the home screen it will sit for a minute then reboot again and just boot loop. i can clear cache and make it boot back up but it just restarts after a few secondds.
please anyone know what to do? this is my second gs2.

Cannot boot into rom.

For a while now I've been running a MIUI ROM without problems.
Today, the phone didn't want to wake up from sleep (tried using trackpad and power button).
I pulled the battery and started the phone back up but after the boot animation it went to black screen and wouldn't do anything from there.
I wiped cache and rebooted, went through the app checking but somewhere in the process crashed and went to black screen.
After several failed tries of pulling the battery and trying to reboot but only getting black screen, I did a full wipe and tried installing a new ROM but have not been able to boot into it.
According to the ROM installation everything went fine, but when I boot the phone up it starts trying to boot the MIUI boot animation then goes to black screen even though I did a full wipe and flashed a new ROM.
After doing various full wipes and sdcard formats, the phone doesn't seem to want to boot into anything even if I flash a rom, and recovery keeps loading up in Safe Mode due to a problem with /cache.
Any help would be greatly appreciated. Thanks!

[Q] HTC Desire HD boots but black screen afterwards

So I have a rooted HTC desire HD with Jellytime on it. All was working great till recently when it would shut down by itself. Today after I wanted to test a new boot screen from Rom toolkit I restarted it and while the boot screen worked great after it finished I see a black screen (backlit so I know its on). I tried going to the bootloader but after I try to go to wipe cache for example it restarts by itself and it gets stuck after the boot screen... Any ideas?
ok an update seems that if I go to the recovery via down button and power it lets me do actions. All this time I went to recovery mode when phone was shut down and plugged into a power source. I did a wipe cache and now it says android is upgrading and now it finished saying starting apps. Hope it didnt get stuck there because it keeps doin the cycle animation but doesn't do anything else.. I ll leave it be for a bit like this... :/ Had to restart it by removing the battery after 20 minutes... same problem as before still...
another update... just before it goes to a black screen when the boot screen finishes an orange light appears just briefly (where the green light appears when it charges)

I flashed the rom again and wiped data and all seem to be ok now. I ll update this because I saw many people have similar problems... thanks in advance for any help!
Have the same problem.
I bought this with the problem that it keeps rebooting all the time.
I unlock the bootloader with htcdev,root with Easy Ace Tool,flashed the new cyanogenmod 11,
but did the same .
At least 3-4 rebooting before open normally.
I said that it must be ROM issue and flashed the KK-LegacyCarbon-4.4.
Did the things should be...flash the ROM and then the boo.img separately.
Now i have black screen and the only screen i am able to get is bootloader and the recovery 4EXT.
I reflased cyanogenmod back but nothing happened,any thoughts???
