[Q] Please Help

My friend tried to flash a rom to his EVO 4g, everything went smooth, installation was a success. However prior to rebooting, he know gets stuck in a blank screen after the evo 4g screen goes away. Anyone ever get this problem ? is there any way to start from scratch?

Reboot the phone into recovery ( pull battery if it's in a bootloop, then restart phone by holding vol-down and pressing the power button)...
Wipe data/factory reset
Wipe cache
Wipe dalvik cache
Reflash the ROM
Ps: what ROM is your friend trying to flash? Be sure it's a Rom developed for the evo (not calling you or your friend stupid...mistakes happen)

He was using salvage zin, I essential there watching like I prolly should have lol but he got impatient and downloaded the rom then went into recoverey wiped data and all the others and then flashed and then got stuck in a black screen and what do you know he's calling me saying I have a problem lol, I'm trying to drink not fix his phone man lol but now I feel bad, I'm a good listener if I'm giving instructions. I'm a nexus s user though so is new to evo by the way

Is there anyway to Odin back to stock ? Or perhaps himdell back?

If it's a black screen and then the phone boots, there's probably just something wrong the boot animation. If it won't boot then he might have a bad download.

Strange issue, need a little help.

I was on my phone, checking XDA, reading news and so forth. I put the phone down to grab some dinner. When I got back after eating I picked up my phone and it was unresponsive.
I held down the power button for a while and nothing.
I did a battery pull and I was able to boot to the Google splash screen with the unlock symbol. Unfortunately it just hung there.
I pulled the battery again, this time I booted in fastboot, then recovery. The clockworkmod recovery main menu came up in recovery, but when trying to do a restore or anything… The blue menu would disappear and not come back. I can get to recovery, but I am unable to do anything with it.
Last night I flashed to AOKP B26 from AOKP B25. I wiped cache and dalvik. I did not do a full wipe, but according to the dev you do not need to. This morning I flashed Morphic’s kernel TNP138-RD-FUV. I used this kernel on B25 with no issues for several days as well. I wiped cache and dalvik before flashing the kernel as well. CPU was set to the default 1190 and default voltages, with the on demand governor.
It is weird that I didn’t have any issues until hours later and the phone wasn’t even in use. It is as if it wiped itself. I am wondering how and why.
At this point I am going to do a full factory ODIN restore. I don’t think there are any other options.
EDIT, as posted below:
I was getting ready to do the ODIN restore when for the heck of it I decided to let it boot normally one last time. What do I have to lose.
I booted to the Google splash screen and set it down. I got a drink and took out the trash. When I came back I noticed it was at the boot animation! It sat at the boot animation for another couple of minutes but 10 minutes after pressing the power button I was booted up.
I let it sit for another 10 before I played with it. But now its like nothing ever happened. And it boots regularly now. I even booted into recovery and it is functioning as normal.
Any ideas what happened?

In cwm is there a 'go back' option at the bottom? If not scroll up and down a few times passing from bottom to top (looping) until it says like back button activated. If back is not active power button makes screen go off and on and does not select.
This is if you are not using touch enabled cwm.

if you can get into cwm then try fastboot and flash the factory images from the boot screen

I am not using the touch enabled. I know that if you cycle through the menu too much it will disable the select button, but if you keep cycling it will enable it. This isn't that.
The screen is on, I can see the clockworkmod recovery & version in the middle of the screen. Just the ICS blue menu disappears completely. no go back or anything. just a black screen with the clockworkmod info in the middle. It is as if its thinking but it just hangs.

id suggest you try to use ADB from recovery to try and at least pull the sdcard files first of all
second id try to flash another recovery from fastboot then boot to recovery and flash a rom or restore backup
if the above doesnt work then factory image from fastboot is it

I was getting ready to do the ODIN recovery when for the heck of it I decided to let it boot normally one last time. What do I have to lose.

HELP!!!!! Ughhh

I did a clean install of AOSP Vicious Toro V1 and anytime my phone boots up or I restart it....it shows the Google logo for about 2 minutes, then says "android" in small letters in the center of the screen for 20 more seconds then finally shows the launcher.
Can anyone explain this? This is kind of frustrating that my phone takes this long to boot and also I have no idea what happened to new Nexus logo.

What method are you using to install the ROM? What do you mean when you say "clean"? I've installed every version of the Vicious ROMs on my GNex and I haven't had that problem. Also, I haven't seen a boot animation with "Android" on it for a while; you're running the default Vicious kernel?

I wiped data, cache, dalvik, battery stats, formatted system, data, and cache. Flashed V1 from AOSP, then rebooted. It showed the Nexus logo once. Then every time after that it takes about 3 minutes to boot and the nexus logo is gone.
I did another wipe, cache, data, format, etc. Same thing happens

All of the jellybean roms (liquid, jellybamf and now AOSP 4.1.1) I've used do that hang on the Google screen every so often for a few minutes but it always boots. I always wipe cache/dalvik/data so its not because of dirty flashing. Don't think that'll be fixed til OTA
As for your bootanimation just search out the new one on here download it and stick it in system/media with root explorer
**edit HERE

Thanks man! I switched over the boot animation and now it boots in 42 seconds instead of 3 minutes lol. It doesn't hang anymore.

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)

Wipe everything (system data cache) and install a stock-ish ROM. What happens?

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???
