[Q] Evo randomly stuck on white screen - EVO 4G Q&A, Help & Troubleshooting

Hey, this is my first post so let me first say sorry if I'm doing something wrong here and thanks a ton to anyone who can help me out in some way...
So long story short - I just looked down at my phone and it was on the white "Evo 4G" screen, so I thought it must have just restarted for some reason (which has never happened, but I usually try to remain optimistic) and I went about my business...about 10/15 minutes later it was still on the white screen, so I pulled the battery and left it out for a minute and then tried turning it on again. No luck-right back being stuck at the white screen. So I pulled the battery again and waited about a half hour before trying with my other battery, which is definitely fully charged and cool, and it is still sticking at the white screen. I don't know what the heck is going on. Anyway, I have an Evo 4G running Warm 2.2 with some netarchy kernel of some sort (one that is suggested on his thread) if that even matters. I can get into recovery, but that's actually another set of issues in itself so if this can be solved without doing a restore I'd prefer that. Okay, sorry to give too many details. Thanks again to anyone who has any thoughts!

this is why you make nandroid backups
If you do happen to have a recent nandroid backup you might wanna restore to that, otherwise the only other other option I can suggest which may still not work but it's worth a try...
recovery > wipe cache > wipe dalvich cache > flash the same warm 2.2 zip you are running and do not flash the custom kernel just yet, see it that gets you to boot

I would suggest wiping cache and dalvik cache and trying to boot up the phone again. I have ran into this a few times using the fastboot option, otherwise never had the problem.

[Q] Odd Problem...

I want to know if anyone knows what the problem/solution of this is. I have a 0003 Evo, the panel that only supports 3 pt touch, ROM doesnt matter, on the ENG HBOOT for CM, AMON RA 2.3
That sums up my phone, the problem is I'm always stuck at the splash screen for 3-4 minutes when booting up. If im booting to Bootloader or Recovery it's quick, hot reboot never reaches the splash screen so thats whatever, but reboot, or powering down then turning on my evo gets me stuck at the splash screen for quite some time. This is my second evo, and continues to do this despite the ROM I use and despite the splash screen image I use. Whats the problem/fix because so far it's only this specific evo.. I've tried google, everyone is complaining about erasing boot, that isnt my problem since everything else of the phone works just fine.

huh?
Anyway, are you wiping data/cache/dalvik everytime you flash a new rom?

What exactly is the problem? It takes a long time to boot? You said it boots up eventually, or I assumed that since you said everything else on the phone works fine.

when i boot up, it is stuck on the splash screen for 3-4 minutes, and then boots up normally. I'm wondering if all that time on the splash screen is normal or if i screwed something up since it takes so long to get to the boot animation
mine takes that long

That's not abnormal. My phone takes anywhere between 30 seconds and 4 minutes to get past the splash screen. This is especially apparent if you've just flashed something. Don't worry, it's just your phone loading

really? I was messing with my friends evo and his screen was there for only 10 seconds, he was unrooted. Is this a side effect of being rooted?

You can by staying on a rom (Of course only to a certain point)
I don't know if I'd say mine stays at the white htc screen for 3-4 min, but close to a good min for sure. Have you actually timed it at 3-4 min?
Once it reaches the boot animation, it's typically ~30 seconds before the UI comes up.

yeah I have timed it, came out to 230 on avg with peaks at 3 minutes but generally around 230. I unrooted, then re-rooted my phone to get the latest hboot 2.1 and see if i screwed something up when rooting and after i unrooted i got past the splash screen quickly, and after rooting it still got past quickly. could it have been my hboot? i was on 0.76, gonna flash 0.93 if i cant keep the current hboot and have Salvage GB at the same time

I suppose it could be the hboot ver, but am not familiar enough with it to say for sure. It's been over a month since I had hboot 2.10, and I don't reboot the phone THAT often to pay much attention to it. FWIW, I've compared mine (hw ver 0003) to a launch day 100% stock evo. Both go through the splash and animation in roughly equal time.
Yours might be delayed because you're running GB?

After Flashing ROM, Phone Boots to Splash, Reboots to Splash, then Fully Boots

This has happened to me a few times, but when I was flashing the Savaged-Zen RC2 today, my phone booted to the white HTC Evo 4G splash screen, the screen then went black, it then rebooted to the splash screen again before finally going to the boot animation and loading fully. Why is it doing this? After a successful boot, it never does it again, but all these phones bricking lately has me nervous. It did the same thing last week with Miui. I've noticed no ill effects, but it's done this with Mikfroyo (a few months ago), MIUI, and now Savaged-Zen. Ideas?
We've discussed this before here:
http://forum.xda-developers.com/showthread.php?t=1028744&highlight=double+white
I have this problem too but I'm not incredibly concerned about it. It did go away for a minute for me, but it's back. Even after I wiped everything that AmonRa 2.3 would let me and did a completely clean install of CM7. No idea. I really do think it has something to do with flashing Savaged Zen though since I never had a problem with it before I flashed that. I may be a bit crass on placing blame there but that's one thing that we've all had in common.
Thanks for the heads up. I tried searching, but I didn't come across that thread probably because of the wording.

If I remember correctly, this is happening with the latest S-Z kernel. It's because of the built-in sbc/no-sbc toggle. Not a bug ... simply designed that way.

New radio update question

So I just flashed the radio update and i rebooted then it went back to the reboot screen it says its formatting cache at the bottom. Should i wait till thats done or just reboot now. For what its worth I just flashed the new evovled rom R3charged.... its been sitting on this screen for like 40 min now. I can go up/down on the recovery menu thats why i asked should i just try to reboot.
Yeah, you can reboot now. The first time I flashed radios, I did the same thing, stared at that screen for like 20 minutes, wondering....

Funny you mention this. AR 2.3 always sits there saying "formatting cache" even though its done when you do a radio flash. I too waited longer than normal and finally just rebooted via AR. All was well. I'm not sure why it does this.
SO, about this radio update, I came into this late, not realizing there were new radios, sorry if I missed a few things.
1, are you guys not rolling PRI back to 1.77 anymore?
2, what's with the Profile update people have reported?? is this across the board, a problem or just random? And I never heard of a Data Profile, Reset. WTH is that?

thx i got tired of waiting after about an hour and took a chance and rebooted so everything worked out. I was nervous for a lil while watching the formatting cache screen lol
Yeah, when you know that it could brick your phone, it's nerve wracking
Swyped From The Hippest Phone Using XDA Premium
Installed via clockworkmod . . .
I just installed the combo file via clockworkmod recovery. Everything went well, so I thought I'd document my experience to keep anyone from having a heart attack while waiting to find out whether or not they just bricked their phone.
The initial flash took about 2 seconds to complete.
After rebooting, I got the icon of the open box with a yellow arrow coming out and pointing at the Android robot. That lasted for about 60 seconds, then the standard htc EVO 4G splash screen popped up.
That was then followed by a similar box-arrow-Android screen with a progress bar along the bottom, which lasted for about 30 seconds.
Finally, the standard splash screen appeared again, which held for about 60 seconds, then my ROM loaded just fine, although it took about 2 minutes to do so.
Not exactly scientific, but I also documented a speed increase after updating. A speed test from 3 weeks ago had me at 1131/82kbps. Just now, I got 1567/115kbps. I probably should have done the test _before_ updating to have a better comparison, but this is what I've got.
Last time there was a radio update, there was pc36img version, with all 4 updates in it. You could see it loading all three in Hboot. This time, I can only fined the radio itself, so I guess I need to do it in recovery, which freaks me out.
BTW, how is everything? Any noticeable differences?

Flashed all of the new updates, even though I had the only thing that was needed updating was the radio. Reprovisioned data, and I have to say: the previous radio, I got very little cell standby drain. This new radio, even lower drain.
Signal seems to hold better too. Speeds seem equivalent, have not run a speed test yet.

My screen is flickering... what the what?

I haven't hit my ten message minimum yet so I can't post this in quite the right thread.
I'm running Quantum 3.4 right now and its been like butter., No problems and no hiccups. Tonight, the phone randomly turned off and when I went to turn it back on it went into a sort of boot loop. It just kept restarting itself as soon as it started the loading animation. All I could get was the vibrate and bit of load screen.
It'll load up every so often, but when it does the screen does this flickering thing and then reboots shortly thereafter.
Any ideas? May not have enough info here, so let me know if more is necessary to diagnose or even suggest a problem.
Thanks in advance
You could try wiping cache and Dalvik to see if that helps. If not, you may have to do a wipe of the data too.
Ok.... So here's some schadenfreude for everyone's amusement. My solution was to do just as Audit suggested, whic, unfortunately, didn't work (Thanks for the suggestion though). So I tried to dirty flash an earlier version of Quantum thinking that the voltages may have finally caused some sort of failure and an earlier rom wouldn't have this problem. No success... So I went all the way to a completely clean flash of the earlier Quantum and still no luck.
Finally, it was time to put the kiddos to bed so I put the phone on the charger and lo there was the little battery saying 0%. I swear I looked when this whole thing started and it said 38%, but nope. 0% So I let it charge and everything's flying along beautifully. Ugh.
Time for a beer.

Weirdest issue ever! HELP NEEDED ASAP :(

Hey guys, I've been having a really weird issue for a couple of days now. For your better understanding I'll list the things that I did with my d855 (Including some stupid ones)
1. I was on a cm 13 nightly rom, I was getting pretty bored so I decided to try out the fulmics 4.2 . So, I did. I flashed it without any hiccups. Everything seemed to be going fairly well. (I did make a TWRP backup and i also checked md5 of the zip file. It matched out)
2. I installed all of my apps that i use, Set up my wallpapers, nova, etc. I used it for a whole day and i noticed that the sot improved quite a bit from cm 13.
3. I'm in my bed, obviously not sleeping, you know how we do. And an incredibly stupid idea came to my mind. I thought "Hey! It's 4'o clock in the morning and i have school tomorrow, BUT WHO GIVES TWO ****S?! why not try out the lg g4 camera app ?!? Now, I had tried it before a long time ago, The camera didn't work, But the phone definitely did. So I wasn't paying too much attention on what the thread said about which version of android it was for. And just like a complete moron i downloaded the thing and proceeded to place the apk and 'libs' folder on my phone. I did give them proper permissions.
4. After that I went ahead and rebooted my phone. It booted just fine. I tapped on the camera app and it gave me an error. So i rebooted again, same as last time it booted up just fine but the camera didnt seem to work. Then suddenly it just shut down and then the lg logo flashed. It booted to the homescreen just fine. Then it turned off again and rebooted again. This loop started to go on and on forever.
5. So I decided to boot into twrp and wipe my art/dalvik cache and normal cache. Then i pressed on reboot. This time the phone didnt turn off, it optimized all of my apps. It took a while but i was on my homescreen and it didnt turn off. So I went ahead and opened up root explorer, located to where i pasted the camera, deleted the libs folder and the apk and also renamed my original camera app from .bak to .apk . Then I rebooted again, and it started the weird looping thing once again.
6. I realized that it boots up just fine if it's plugged in. But it seemed to turn off after 5 mins or so even when plugged in. I thought I messed up my rom or something so i decided to check by entering into recovery. But the result was the same. It just turns off. So since it was turning off even when i was in recovery i thought it was a faulty battery.
7. So i busted out my ZTE pocket wifi router and proceeded to take its battery and hold it up against my d855's battery pins with my finger. (Probably not safe) And the phone seemed to work just fine. I could use it for days without any issues. So at that point im like 110 percent sure its a faulty battery. Fair enough.
8. But, just to be certain i thought lets try doing a factory reset and flash the fullmics again. Result = Wank.
Then I wiped the cache again. Result = Wank. Then i decided to restore to the backup i made earlier that day. Result = An oreo to be given to the one with the correct guess.
9. At this point i wasn't 110 percent sure that it was a faulty battery. I KNEW it was a faulty battery. I was feeling it in my left testicle. So I decide to finally sleep cuz you know, gotta get some sleep, got a big day ahead of me tomorrow. Cuz I dont have my phone. So, I prepare myself and go to sleep.
10. The next day I decide to give it one last shot. I was thinking about wiping it clean and restoring to the backup again.
11. This is where the interesting thing happens. Bear in mind, I am NOT plugged in. Im on my G3's battery. I hold down the volume down and power button. The lg logo shows up. I let go of the buttons. I press them again. The white factory reset screen shows up. Now, I left my phone on that screen for legit 20 mins ladies and gentlemen and it didnt turn off once. But as soon as i click yes for twrp to launch the phone turns off before the twrp logo can show up. I tried the same thing with the ZTE battery as well, and it worked just fine. Only this time it actually booted to twrp. And it booted into the system as well.
Now, wtf is this? Wouldn't the phone turn off in the factory reset screen if it was faulty? And if the battery isn't faulty, then why does it work with a different battery but not with the lg one?
Now, My question to you guys, WHAT SORCERY IS THIS?
Help me out people. Expert help needed. TIA
*sigh*
It's a faulty battery mate. The phone stayed in the factory reset screen because the battery usage was basically insignificant. When you tried to go to recovery mode, the phone used more battery and boom, dead phone Happened to me too, new battery solved it.
