I'm new to cellphones. I bought a used EVO 4G, rooted it and installed Cyanogen - once. In the process I've done quite a few different commands, but, don't have much memory of them and what they all do.
After a while my screen cracked. First I tried simply replacing the digitizer and when that didn't fix it I got a digitizer/lcd screen assembly. It still didn't work and the problem was the connectors on the main board for the screen, digitizer were bad. I then got a new main board and am getting farther, but, have a new issue.
The first couple of times when I started the phone I wasn't watching but I heard it making sounds and so forth but after a while it just went black. I did a hard reset (clear and then reboot). After that I again tried turning it on (without watching the whole time) and it acted the same. Then I watched the who process and found that it would get as far as the grey background with "4G" in yellow and white letters. After a while the screen would go to sleep but I can't pull the bar down to unlock the screen.
I know there are lots of commands and things I can do with adb, but, it doesn't appear to to be enabled. When I run "adb devices" on my computer while the phone has the grey background and the white and yellow "4G" it doesn't list anything. Then again it seems if the digitizer isn't working there should be an error when booting.
I see there is a bootusb option but I don't remember what it does. Does anyone have any suggestions?

I got my hermes from my friend, (HTC X01HT), she didnt want it because she dropped it and the ringer didnt work. it had only gotten unplugged, so i opened it, plugged it in, and had an awesome phone.
I dont think this is normal, but from the time she gave it to me, the screen made an awful highpitched ringing noise, (very uni-directional, it was weird).
Anyways...
now, the screen is just white. for a little while i could get the screen back, just by opening and closing the slider and hitting the power button a couple times.
Sometimes the today would display, then it would jarble up a little bit then fade to white, but i cant even get it to do that anymore.
Anyone else seen this issue? i'd hate to get rid of a perfectly awesome phone.
Thanks!
(also, if someone could post a picture of the device locked screen, where you have to enter a PIN to use the phone, that would be great, im trying to get into the phone with activesync, but its locked, and i dont know where to push the buttons.)
thanks!

Looks like the screen is unplugged, really. Maybe you need to disassemble further, like http://www.pdacenter.ru/razborka/razbor_hermes/ shows?
keep in mind, it worked fine for almost three weeks before the screen issue started... but i will try that when i get my hands on a small flathead again.
There's a whitescreen & D-Pad failure issue that can be caused by many things, including DROPPING the phone.
I wrote a guide about it which seems to be quite successful for many people.
http://forum.xda-developers.com/showthread.php?t=321163
so after trying a hard-reset, (which somehow displayed on teh screen), and clicking no, i was able to get the screen back... only this time with the moved screen problem, wrapping around at the top about 1mm.... and the buttons didnt work.
i tried your guide, but now im stuck at the white screen again... :/

I have been using CRC 12.11 for a while. A strange problem started all of a sudden. My screen went white although it is working. Soft reset didn't solve the problem. Hard reset solved the problem for a while and then it came back. I noticed this at the time it happens. While everything is fine, the screen fades out, a few lines like scratches appear and then the screen stays white. I hear system sounds, the phone rings but no display. What has caused this?
I flashed another ROM but when my phone restarted it was still white. I hard reset and now I am waiting. If it reappears, it means it is a hardware problem right?

I had this same weird issue once on my rom, i think it's because of the Big storage bug.. Flashed OEM rom and went away.. only saw it once!
I reflushed several ROMs that I used to have before without problems and still have the same. I can't install OEM, I think it's because of the bootloader version but I don't remember exactly the procedure to correct this and I don't know if it's worth the effort in downgrading to OEM.
Another thing I just noticed is that the screen is not aligned in the center. There is a small gap on top of the screen as if the image has moved downwards. Maybe this is the cause of the problem. Noone had similar issue? I don't believe it has to do with big storage because I have been using it fot a while and this never happened before, not even once.
Any ideas will be apreciated as my only choice right now is to buy a new phone.
same thing
i´ve been looking around and some people say is because the magnet in the pouches, affect in some way to the screen ribbon or something like that.
that is a common problem with the hermes, if u search the forum u'll find a couple of threads like this.
it's a hardware problem, next symptoms will be the green/red buttons and d-pad stoping to work
I know theres a few links in the FAQ about the white screen issue, its fixable in some cases.
problem solved!!!
i just took it apart, one of the ribbons which connect the green and red buttons was kindda folded also the connectors , so i just blow some compress air and tried to unfold the ribbon, put it back together and voila! like new. Just be carefull cause it´s like fragil.
same exact problem word for word
The same exact thing happened to my hermes. I guess I can attempt to put mechanical skills to work and fix this problem.
I have rooted my desire z (about a half year ago) and now I am having a problem.
When I boot my phone my screen stays black during the phase that normally would show that htc logo and white background. And after that colors are weirdly blueish (it goes back to normal after I put my phone to sleep and wake it). Also bootloader is black (I know that it boots to bootloader because when I push vol- and the power it goes to clockworkmod). And clockworkmod is also weirdly blueish. I got this problem when I was trying that unofficial CM9 rom and I have used superwipe, tried several other roms and backups of other roms, but the problem don't go away. Any ideas how to fix this?
It seems that my screen problems change when I open/ close keyboard. So could the cable be a bit broken?
Most probably the cable. If you are still in warranty, take it to be serviced. If not, I'm sure that wouldn't cost much.
Either way, sounds like a hardware problem.
I JUST got my LG G2 from sprint less than 4 hours ago and as soon as i got home i rooted it using ioroot25 that i found somewhere online (if its important i can dig up the link but figure its probably irrelevant) and installed TWRP recovery, made a backup, not a single issue, then all of a sudden half hour later i pick it up and turn it on and the screen is mostly white with yellow lines (that move/respond to touch and whats supposed to be going on on the screen) and it will not show any sort of picture just kinda yellow fuzz lines...it looks just like some phones ive seen with cracked/ faulty LCDs but if i hold the power button and up or down to hard reset it, the LCD starts working again upon boot, and continues to work untill the LCD turns off for the first time after booting and i try to wake the phone again, every time i turn the screen on when its on it goes back to fuzzy lines with no way to make it start working other than restarting the phone with the buttons on the back.
anybody ever seen anything like this before? it cant be a broken or cracked lcd cuz when it first boots it shows a crystal clear screen and everything works fine untill the first time the screen turns off...im guessing i am more than likely going to end up making a trip back out to the sprint store tomorrow for a manufacturer defect replacement? any insight into this strange problem would be greatly appreciated!

Faced similar problem with LS980
I am also facing similar problem with LS980.
Only additional mistake i have made is -
I have installed TWRP recovery for D802 instead of LS980(Seller labeled it as D802). After reboot into recovery mode, My lcd showing only lines.
Any suggestion/help ?
nothing exactly meaningful, just wanted to mention in case other people had similar experience.
well also it may have implications after the next OTA / post-root-if-that-happens
for reference: to be safe, for a while now I have had both of the known IPs blocked on my router.
- maybe a week ago, tried to scroll into Home->Recent and got a solid blue screen for 5-10 seconds. didn't touch the device, it auto-reboots, then everything ok. version number unchanged still etc_02.etc like we all have.
- few days after that, Prime TV was playing and kept playing fine, but usb went sideways. reconnecting usb, power looked ok but still nothing. tv app kept playing 100% fine just no HID. stupidly did not try the remote. recycled power, and got stuck at (white-logo)amazon screen. power-off, wait a while, tried a few more times and always stuck at (white-logo)amazon screen.
-- removed the 2 blocked URLs from my router and booted, everything back to normal. (version number still same etc_02.etc)
wasn't even going to bring all of this up, who knows I may have a flaky KFTV, but then
- today got the solid blue screen again trying to scroll Home->Recent*. as before, box eventually rebooted itself, without having to do anything, and everything normal again. (and this with both IPs still re-unblocked)
if nothing else reminded me to re-block both URLs lol. but it is a very small and random sample size so far.
semi-weird: the first blue screen, and the usb breakage, both very hot days here, it almost could have been temp-related (but box did not feel warmer than usual) - but then blue screen today is bad weather / cold here, so yeah probably not.
*since it happened same way both times, could easily just be some bug about Recent, or in the KFTV Launcher
