Ok, so my brand new EVO was working fine. Power save came on, and turned the screen off. I hit the power button, and you could see the backlight light up, but nothing would come on the screen.
My soution was to remove the battery, then reinsert it.
Now it just gets stuck at the white EVO screen!
Does anyone have anything that can help me with this?
Try keeping the battery out for like 5-10 minutes then put it back in. If that doesn't fix it, might have to do a Hard Reset or bring it back to the store for a new one.
Tried to hard reset, but nothing happens. It stays stuck at that screen.
Hard Reset meaning a full wipe of the phone. I think it's Vol button and Power button at same time. And then choose hard reset or something of that nature. Yeah Vol Down and Power
http://www.knowyourcell.com/htc/htc.../463924/how_to_hard_reset_the_htc_evo_4g.html
Yep, that's the procedure I went through to hard reset.
Like I said though, that didn't fix it.
Bring it back to the store then man or keep the battery out for a few minutes (if you haven't tried that yet) or possibly take SD card out?
When I take the SD card out, it comes up with some new "artwork" on the boot screen that leads me to believe it either can't be booted without this card, or ****'s just broke.. IDK.
It's like a phone with a red X on it?
That's probably not the best description, but it's close.
Ok, so this time taking the SD card out worked. It booted.
I would suggest try to bring it back asap before they run out but maybe someone else has gone through this before and help you. Sorry bro, keep us updated though
EDIT: Nice! Thought that might be it. They were having SD card errors which is why the OTA is being sent out. Glad it worked out for you
Nothing to be sorry over.
My personal opinion at this point is that the SD card got knocked loose, and wasn't seated correctly.
That seems like a horrible design. How are you supposed to see if the pins are aligned correctly?
I mean it should just slide in, but maybe it doesn't fit the tolerance every time.. IDK.
Again, to recap what I did to fix it.
I removed the SD card, reset it to factory default, and it booted.
After that, I put the SD card back in, and all is still well.
Thanks for your help xda-dev forum!
Ok, nevermind. It's still broke.
Seems like when power save comes on something gets hosed.
I'm half afraid to do the OTA update, as I want to root this thing.
Ok, I'm about 90% sure the problem is with the SD card being seated correctly.
Every time I put the card in, the phone freezes within a few minutes.
If I have no card inserted, it runs without a problem.
This is the problem the OTA fixes, you can take it back to the store and see if they will swap it but I'd be willing to bet they tell you to apply the OTA.
I did the OTA, and am still having this problem.
Took it to the store tonight, they agreed to replace it, however their systems were down, because of a storm. So I will be waiting until tomorrow i guess.

Whenever I do the update and restart it get's stuck in a continuous loop. I already returned the phone and they replaced it but when I did it again it did the exact same thing. I just learned and didn't install the update again :/
I don't know what I'm going to do now seems like it's stuck. If I update I don't get the latest fixes but if I do it messes up my phone and it restarts over and over again uncontrollably... bleh
Just got my replacement phone.
It seems to function properly so far.

It might be worth doing the update in the store or having them just perform the update so they can go through all the hassle and you just get the result. It's what they get paid to do.
This time they did the update in the store before even giving me the phone.
I think they were just super swamped yesterday, and the early people didn't get updated phones.
The store guy told me I was the sixth return, but they sold "over a lot" of units.
I rooted my phone, now I want to reset it to factory default
I hold down the vol and power on, I get the white screen When I want to go in to recovery, it reboots and hangs with a pic of phone and red w/ xclamation over it
it there any other way to hard reset???
I have a co-worker with Droid incredible and every time she turns the device on, it is stuck at the white HTC screen. Once in awhile, she'll be able to see the lock screen, but then the device will reboot again. I tried going into the recovery by pressing vol. down + power, but when I choose recovery, it gets stuck at the white screen again.
She does not have an insurance on the phone, is there a possible fix to this problem?
Thank you in advance.
Is it rooted or what? What did she or you do before this happened? Try to flash a rom or diff kernel?

Download this file
http://www.fourty.net/~berzerker/stockstuff/PB31IMG_3.26.605.1_RUU.zip
Rename that file PB31IMG.zip, put that on the root of the SD card, boot the phone into bootloader mode by pressing vol - & power. Let the update run its course, and she will go back to a TOTAL stock 2.2.
EDIT: She will lose all her texts, have to re-download all her apps, and set her homescreens up again, but I don't think you have any other option if it keeps getting stuck at the white HTC screen.
If it's stock already or if rooted and the PB31IMG from the above post doesn't work, she simply needs to do a warranty exchange. We are, after all, still within the warranty period.

How would that not work? Its the stock rom, signed. I myself have done this before. Why go exchange it and get a crappy refurb (most likely SLCD )that, more likely than not, has problems? Why not fix the problem and keep the one that she has?
If they didn't want to do that they could go to shipped-roms.com and download the RUU from there and flash it back to stock that way also.

It ain't gonna work if it's a hardware failure, which seems a bit too common with the first run of Incredibles. No software is going to fix a problem with the SoC, which is why I said if the RUU doesn't work, she needs to do a warranty exchange.
The phone is completely stock.
She had to cut the line off and use company phone for about a month or two due to her personal problems. Now she's trying to get back on line with Verizon, but it's keep on rebooting itself so there's noway put it back on again..
Does Verizon/HTC do warranty on the phone even though she's not on the Verizon with the Incredible?

I doubt they do, but you could just put it back on the plan, and take it into a verizon 30mins later. Tell them you hit *228 & #2 to update the prl and your phone rebooted and keeps doing so.
Thanks. If everything fails, I'll just go ahead and do that..
There's another version of recovery that lets you wipe the phone - you can search if I'm wrong, but I'm pretty sure that instead of pwr<->vol down it was pwr<->touchball. There, you'll be able to wipe the phone.
I had a similar problem with a phone that I just sent back for warranty repairs. The upside was I did get past the white splash screen. The downside was a few days later, the phone finally kicked the bucket and wouldn't power at all.
This fixed my issue. I was able to retreive my pictures after everyone else was saying to forget about it including HTC and Verizon.. I think this is a pearl as so many Incredible users have posted the constant reboot issue. Thank you Thank you Thank you!!
Another rebooting SLCD Incredible
Hi guys,
Just wanted to let you all know that this week, my wife's SLCD Droid Incredible started randomly rebooting. I had her on the Virtuous stock-based ROM and the SLCD ClockworkMod Recovery, and she had a TON of crap apps (pregnancy, game, live wallpaper, etc.)
I was able to back up the phone if I left the back cover off, but everything I did was time/heat sensitive. I wiped the phone and when setting it backup, got the bootloops after downloading only five or six market apps, not running any of them.
Last night I went back to stock (S-ON, Stock November PB31IMG.zip bootloader update). Again, after getting back to complete stock, it locked up after a few market apps were downloaded.
I called Verizon this morning from MY AMOLED Incredible, and they first had me describe the issues in detail (30 minutes), then try and repeat the issue (20 seconds after opening Google maps and starting a navigation session *quick heat*). She transfered me to "Level 2 Support", then he wanted to walk me through resetting to factory defaults on the phone via the SD card and storage settings. I noticed he wanted me to wipe the Internal storage, so I told him I needed to first backup the DCIM folder full of personal pics and videos to my SD card. He waited patiently while I backed them up (20 minutes). When finished, he had me wipe the phone+EMMC. I left the cover off so we could get through the initial setup, the put it back on after setting it up. He had me do *228 option 1, after the phone rebooted he wanted me to try and do "normal tasks" like downloading apps to get the phone to repeat the issue, if possible. I simply opened up Google Maps, started navigation and 1 second later, the phone went into bootloops. He promptly set up an "in-warranty" replacement to be overnighted to my house.
I do not have any monthly insurance on my phones, so I thought it was great deal that Verizon can issue an advance warranty replacement with return shipping, overnight, no less. Most companies would tell a customer to contact HTC directly. I am sure that is what Alltel used to do. I don't think VZW did it because we have corporate discount, I think this is standard service they provide for all their customers.
For any of you having this issue, here's what I recommend:
**If your phone is continually rebooting, pull your battery and let it sit out of the phone so they can cool for at least 20 minutes... Alternatively, you could probably put your battery in the freezer for 10-20 minutes and get a little extra "cold time" out of the phone before it bootloops**
1. Sync your apps with an app service like Appbrain to easily retrieve the list of apps you had.
2. Backup your call history and bookmarks using an app or two from the market. I have used free ones before, they should be easy to find.
3. Back up your Internal Storage and SD card to your computer (and preferably to a backed up location on your PC)
4. Revert to S-ON, and Stock ROM, if you are not already on one.
5. Set up only the basic functions on your phone (don't download any apps), then test that it is a heat issue by simply opening up Google maps and navigating anywhere.
6. Call Verizon and wait PATIENTLY on the phone as they walk you through their hoops. Expect this to take an hour or three. Just do as they say, as they have to make sure you indeed have a defective phone.
7. Profit.
Hope it helps,
jakewill

Ditto I have always had a pleasant outcome talking to the phone reps. Remember they are just doing their job and they are probably doing this exact same long process all day..
Wish I could say the store reps we're just as good but it's pretty hit and miss.

Just got a defy last week. And now sometimes the phones goes to sleep mode and it wont turn back on, unless you remove the battery and put it back on.
I haven't modified, or rooted. Just the stock rom.
I also did a wipe to see if it fixes the problem but after the wipe it still happens
You can use OSmonitor (one of my favourite market app) to see system log, or you can use "adb shell" when phone is sleeping, and see if u can log in, and if you can, use "dmesg" command to see the system log; and troubleshot the problem and mess around for hours and hours.. You can post Log here and see if anyone or me can tell whats happening..
Or you can just flash a newer firmware and maybe root , and probably see the problem gone and forget about it.
Thanks for the reply. I haven't rooted it yet. The firmware im using is the latest one, at least that's what it says on the SYSTEM UPDATE.
I have the same problem and generally during wifi connection. in attachment there is messages from OSmonitor and in 31 and 32 minute it was reset. If someone know what happened with my phone let me know
I'm not sure if it is software issue. Since you just got it, you better return for a new one.
It started after about 2 weeks after I got this phone. So, should I go and return the phone for new one? It is one possible way to fix it?
I don't know your supplier's policy, but it doesn't hurt trying. And if you try to fix it yourself by rooting the phone or flashing roms etc, you may actually hurt your chance.
if i were you i would upgrade to froyo and return the phone if its not fixed, but the sooner the better
do you think that it can help upgrade to froyo? this problem can be caused by version of android? now i check the phone and notice that the problem dissapear if the wifi is turned off. any ideas?
I have this problem too. Pretty much disappointed by this kind of behaviour and i think its a big problem which Motorola should fix very fast. I think I'm going to send it to repair service.
I believe to do sth with it without sending to service. If it is impossible and it's just a hardware problem it would be necessary but if it can be fixed by myself I'm waiting for your ideas
okay the supplier replaced the battery and after 2 days of testing its still the same.
Going to try and see if i can upgrade it to froyo.
Any vid tutorials on upgrading?
hey all-
youve been a great community since ive been around (last december) and i was wondering if anyone had any insight on a problem im having.
I recently got a replacement phone that is refurbished from sprint, because the power button on my old e4gt was completely stuck
when i got the phone i immediately rooted it and went to my usual set up of Blazer 4.1 with the rogue 1.4.1 kernel.
since then ive been having some trouble:
the touchscreen is very wonky, ill be in the middle of texting and it will all of a sudden start selecting things all over the screen. simply turning the screen off and then back on usually works, but ive noticed that the frequency of this is increasing. also the menu home back and search keys all pick and choose when they want to work, and when they dont. sometimes ill press them and they wont work, other times ill be browsing the web and the menu button will start going off and on, without me pressing it.
ive also been experiencing quite a few random reboots, this wouldnt be such a problem however sometimes the phone will just shut off, with the red led light still on, but the screen wont come on when i press the power button. ive also noticed that sometimes the phone will randomly reboot, and then hang on the samsung screen. this has happened a few times at night and caused me to miss class because my alarm didnt go off (lol). when any of this happens i just hold down the power and vol up button to reboot into recovery, and then reboot the phone from there.
the only visible difference i can tell is that under the build number it says: "Blazer v4.1 ~ PI:FG-X^2I^2
i dont remember the last part of that being in any of the previous build numbers; ive been running this build pretty much since it came out, theres just something about the speed, snapiness, and battery life of this gb build that has me hooked.
if anyone knows if these problems are hardware related, or if i just had a bad flash, id greatly appreciate your feedback.
i know this has turned into a long post, but i just have one more question:
i use google play music as my music player, and absolutely love it. my favorite part about it is the fact that i can "download" songs to stay available even when i dont have a data connection, this comes in reallyyyy handy. HOWEVER, i use titanium backup to backup my apps, and when i flash to a new rom and restore play music, it restores all my music, but not the music that i have stored on the device. this is annoying because i then have to wait for a stable wifi connection to download the 500 or so songs that i usually keep on the device. My question is whether or not there is a way to backup all of the cached music, or if i could move the app+app data to my sd card, so i wouldnt have to redownload all the songs when i flash a new rom.
again youve all been a great community and im thankful for all the devs and all the work they do. i apologize for this post being so long, i dont usually post much but when i do ive always gotten the solutions for the problems ive had.
have a great day everyone, and you stay classy san diego
replace
put the phone back to stock and see if these problems still occur. If the do still occur then take it into a service center and have it replaced

A service center should take the phone apart and check the sticker in the inside. You could also just buy a battery from amazon and use that when taking it in.

Hello Smart People,
I have an unlocked at&t note 4 and for the past 2 week my phone will freeze for 1-2 minutes then it will be useable again or if it is not doing that will randomly reboot when I am using the phone. So benging of last week I called tmobile since I have them now. I spoke to tech support. Told them my problem and they had me turn off the phone and take the sd card out and then boot into recovery to clear the cache. That did not work. Within 5 minutes of have the phone back at the home screen it froze again. So tmobile said that it was not the sd card in the phone. Told me to turn the phone off and put the sdcard back in the phone. Then I rebooted back the home screen. They said that at this point all I could do was back the info on my phone and do a master factory reset of the whole phone. I told them I could not do it right then and there. They said if it still happens after the master factory reset then you will need to get the phone reflashed to have the software fully reinstalled and they could not do the reflash of the software since my phone was an at&t branded version of the note 4 so I would have to call at&t and see if they could reflash it for me. So the next day I backed up my phone using samsung smart switch software on my pc and master factory reset the phone from the recovery menu. When it was done I resetup the phone and it still froze and reboot randomly. So I called at&t and spoke to tech support and told them my problem and what tmobile say to do. They told me they could do the reflash but since I am no longer a customer they was nothing they could do for me. But I could go to best buy to a Samsung experience store and they could reflash my phone with for me with the latest software that at&t had out. So I went to the Samsung store inside of best buy. I told the lady my problem and what tmobile had me do and what at&t told me. She told me she could do the reflash but I already had the latest version of the at&t software on my phone all ready. I told her that tmobile told me the hardware in my phone is all good and that however I got the at&t update it did not apply correctly and that I need a reflash. She took my phone and started to plug in to her computer to do the reflash. After it was done she gave me my phone back. On the screen it was in recovery mode trying to reboot back to the phone screen. I showed the phone to the Samsung store lady and she told me I had to wait and it would reboot to the home screen. I thanked the lady for helping me out and left the best buy store. Got to my car and the phone now had a black screen so I took out the battery and put it back in and turned on the phone and it booted in to recovery mode not the home screen. From the recovery screen I picked reboot the phone and once again booted to recovery mode. So I walked back in to best buy and talked to the Samsung lady and was like this is very weird it should not be doing this. She also took out the battery and put it back a few times. Still phone was rebooting to recovery mode and not the home screen. So she called her tech support to figure out how she could fix my problem since now my phone was 100% not useable. The Samsung lady’s tech support had her plugin the phone to the computer again and reflash the software. But it failed at 3%. She was told to tried it again it failed at 20% this time. So she was told try it again and it failed this time at 50%. So she was told to try it one last time and this time it went all the way to 100% and she keep the phone connected to the pc until it was fully rebooted but again it rebooted to the recovery more screen not home screen. She told me that she would have to keep my phone and next day ask Samsung for the full flash of the software to download for my phone since she only had the latest update. So I left my phone with her and waited for her to call me and let me know that my phone was all good to go. I went back the second day after giving Samsung my phone and the lady told me that she did not run the full flash because she came in the first day after I give her my cell phone and it was at the home screen. I thanked the lady and left the best buy store. When I got home I download an app from the google play store and the phone rebooted on me. So the problem is still there! The phone so far has not frozen on me which I guess in grand scheme of things is good, but I am not calling this over just yet. So smarter people of xda Is there anything I can do to fix this phone so I can still use it and not have to worry about it or is it time to just bite the bullet and get a new phone even though there is nothing out that I like.
We're in the same boat
I am having the same exact issue. I just got my phone flashed at the Samsung experience kiosk at best buy only to use it and find out it still randomly slows down then crashes and restarts. It at times crashes as its restarting and continues a boot loop for a while. What can be done?
1.Battery is about to die or 2. Uninstall good luck
I'm having the same issue with my ATT Note 4 it started a couple weeks ago as well
Was in the same boat
Install a app called WakeLock from the play store. Use the level 4 option and yours troubles will be gone.
I had the same issue for 2 weeks and then came across this gem on one of the forums. Has not caused an issue for the last 2 weeks now.
Is that app wake lock powermanager be Darken? There are a few wakelock apps.
I'm in same boat as well. NOTE 4 worked great until a few weeks ago. Then MANY freezes, reboots, etc. I almost think aTT pushed something down intentionly (ita called planned obscellesence) to force an upgrade. Not reall5, but I do wonder .

Worked like a charm!
Edit. Worked for a while but apparently my battery was trash. New battery came yesterday and solved all issues i was having.
WOW! I was ready to throw my note 4 in the garbage because of all that crud! This app is AWESOME and did fix my issues. Thanks a ton for those that recommended it. My note 4 runs wonderful now, and probably will be PLENTY sufficient for me for another 2-3 years. Unfortunately, this issue has REALLY dampened my outlook on SAMSUNG and cell companies for that matter. It's in their best interest that people DO upgrade phones every 2 years or so.
Help please

battery issues
Just want to say was about to throw out my note 4 this week for the same issues. I installed the wake lock app (darken), have it set on 'partial wake lock' and AMAZING my phone seems to be operating normally! Thank you, and spread the word.
Wow! Thanks to all for the great tip. You saved my Note 4!
Since the latest OTA ROM upgrade from AT&T, (6.0.1, baseband N910AUCS2EAK5) my normally solid note 4 phone worked like garbage! It would slow way, way down, especially on a strenuous task, and quite often reboot spontaneously. It was so frustrating, I had to carry a second phone just to make sure I could be reached.
I did everything - wiped cache, factory reset and was just about to ODIN flash an earlier ROM when I can across this tip on XDA. This Wakelock app is phenomenal!
It seems as though Samsung / AT&T released the last patch with faulty power management. This app bypasses the whole issue by NOT allowing the phone to enter deep sleep. Problem Solved! Perhaps battery life takes a small hit, but who cares! We just have to hold on until the Note 8 arrives!
---------- Post added at 02:47 PM ---------- Previous post was at 02:39 PM ----------
Totally donating to Darken (via play store) for saving my phone from the garbage, and saving me $500 to upgrade to a phone I don't want! Best $2.31 ever!
Still need the app
I just did the OTA upgrade from AT&T. I am now on baseband N910AUCS2EQD1 (6.0.1) I was hoping this upgrade would fix the problems, but it didn't. Still need the app!
my daughters note 4 has been randomly rebooting and sometimes when it reboots it sticks at the att symbol or it even goes to download mode? it started after att did a update . i told here to try the wakelock and let me know how it goes but has anyone had it reboot where it says could not reboot then has the android and do not shut off target?
Would anyone happen to know how well Wake Lock plays with Good Lock and/or power saving mode? My battery is ready to retire (seems to be at about half-capacity if that's the right terminology, new one on the way) and I've been having these freezes and reboots happen to me over the last few weeks; often at annoying inconvenient times.
My new battery should be here before this week ends, but I'm just looking for some insight for the few days in the interim. Thank you in advance for any responses.
...Noted (SM-N910A)
well tried wake lock and it seemed to help but did not fix the problem, phone was flawless and worked perfect before 6.01 . now reboots during call and downloading updates from playstore ect. sent it to samsung and they said it would be $70 to repair so i sent it in. they called and said the screen has ghosting and need a lcd, i think they broke it and didnt want to pay for it but they had it and i had to get it fixed. i now have it back with the newest att rom and updates with a new motherboard housing and screen for $185 but it works perfect like it did before with 5.0 so there is a hardware issue gong on with certain boards from what i have been reading in other forums its the early production ones. must be ram or internal sd who knows but whatever it is the marshmallow rom brings it out. did not want to spend the money but it was worth it. no lag and very snappy again and no reboots. i wish samsung would admit there is a issue with the note 4
