[Q] Problem: Unresponsive screen after update

My wonderful wife gave me an Acer a500 for Christmas. Awesome gift. I had rooted it immediately with no problems, since all of my phones and families phone are rooted, it just seemed to be the natural thing to do.
As someone that "plays" with their android a lot I did all of the backups. Well, the time came to have my tablet "approved" for use at my company and also have the appropriate "encryption" software and keys added. Just as a precaution I decided to restore the original backup and unroot the tab.
All was going well until I received the update message. I went ahead and downloaded the update and ran it. During the install process it froze. I thought it was just busy so I left it for a good 20 minutes and finally realized it was frozen. I rebooted and it went through a couple of reboots and finally settled on the lock screen. But now I find the touch screen unresponsive.
I plugged in a mouse and keyboard in hopes that I could get back into it and start over, but, although, the mouse shows up, it is jumpy sluggish and will not grab the lock to slide open and eventually freezes.
I have tried all of the "update.zip" files I could find and they all fail at one point or another.
ADB allows me to explore in shell but since I unrooted, I cannot get su privileges.
Acer is of course, useless and the vendor it was purchased from is worthless.
I have been through every thread I could find and tried every trick I could come up with. Now I'm just stuck.
Any help is appreciated

I've had this a couple of times already. Usually just turning the screen off and on a couple of times does the job (the issue seems to be with the driver, also on various custom roms). Just try it after each off-on cycle, most of the time it takes no more than two or three tries, though there are exceptions.

Thanks, but it has been rebooted many many times since it's demise.
Decided to skip sleep tonight and keep plugging away.
I found an update.zip recovery file for an a501. Figured I can't do much worse so I went ahead and ran it.
It froze at about 95% but.........
Good News:
The tablet is responsive and touch panel works again.
Bad News:
It boots straight into system settings and although you can open the settings menu, nothing actually launches.
Decided to try all of the old update.zips and still everything fails.
No more ADB response.

When you originally unrooted your device did you revert back to the stock recovery or did you leave cwm on your device?? If you left cwm on your device that may be the problem with the update.zips and OTAs.

You are sooo right. I've never gone back to a stock rom before and I completely forgot about reverting to the stock recovery.
As a matter of fact, I was on Civato's Flexstriker 3.2.1 rom with the new CWM before I reverted back to the stock rom.
Well, at least we've determined my stupid mistake, but now the question lies: "How do I get back to any working rom?"

Here's an update. I did find an update.zip file that also begins to load but does not finish. It stops at 95% still.
I will attach the photos in case someone notices something otherwise I am at a loss. In addition to all of the above, I tried everything I could to get into APX mode but nothing. I am willing to try almost anything at this point, so all suggestions are appreciated.
Something I noticed was the recovery for the a501 was android with gears spinning in the body. The recovery I have now is a package with an arrow. The recoveries are different. The current update file is Acer_A500_1.145.05_COM_GEN1
So this brings me to a question: Can I put Thor's 1.6 CWM back on the a500 and at least work from there? I do have my original backups and thought I might be able to get somewhere that way.

[Q] GT-i9500 has no OS installed.

Hi everyone I just recently purchased a used S4 the GT-i9500. Everything seemed fine until I got home. It detected my T-Mobile Sim fine but I could only access 2G data and could not connect to any WiFi network I came across. The rom was stock 4.2.2 and the phone was rooted pre purchase. So after fiddling around for a few minutes I discovered the previous owner had flashed TWRP v2.4.1.0 as his choice for a Custom Recovery. Now at this point I had decided to flash on a Custom Rom and of course I first made a backup before flashing on WanamLite. Now after attempting to flash it I immediately received a failure. I tried turning off the signature verification and it did not flash. Now in my frustration i attempted to wipe everything and tried flashing Omega Rom v14. Now i was able to go through with the installation and choose what I wished to install and when I pressed Install things went along smoothly until I hit the app SecSafetyAssurance.apk where it freezes. This is a bump that I've run into at least 5 times already. I changed certain options I wanted to install and eventually made it past this and I am prompted to reboot. Now when I do this to my dismay I just receive a black screen. Upon pulling out the battery and attempting to reboot I still receive a black screen. when I boot back into the Recovery and attempt to reboot the system from within TWRP it warns me saying No OS Installed Are you sure you want to reboot. Im at a loss of what to do. I have read about other members suggesting to use ODIN but I am very confused about how to access Download Mode in order to flash a stock rom from SamMobile.com. I could use a few tips or maybe a few options that I'm left with in order to obtain the operation of my phone again. I would like to get my phone back and Im sure some users can relate to how Im feeling so any help at all would be greatly appreciated. Thank you very much in advanced!

Flashing through odin is one option.... some users have reported that there were some hiccups when installing omega 14 because of the aroma script.....try a different rom...there are many others to choose from....or you could flash stock via odin as said on the earlier comment good luck

Feedback
Today I attempted to use ODIN to flash now I am still currently attempting this. When I press the volume down key, power, and home button it takes me to the custom recovery TWRP instead of download mode. The phone did this when I first purchased it. When I still had what appeared to be the stock rom it would always take me to the recovery. When I would use the volume up instead of down it would take me to the factory test mode now mind you this happened when the OS was still installed. When i try that combination now i just receive a blank black screen. Are there any other ways to boot into download mode?

[Q] At my wits end

tl;dr phone is in some kind of bootloop, tried flashing stock firmware (successful but can't get past start splash screen), plz halp me
So I was just simply browsing on my phone on reddit is fun app, some Google Chrome sites, and 9gag. So then I saved a gif on 9gag and the phone just gives up on me. It went straight to shut down without any warning whatsoever and proceeded to restart. Thinking that it was just an unusual one time thing, the phone kept rebooting and I started really getting worried. I kept getting the Samsung Galaxy S4 splash screen and after that a black screen and then it vibrated twice and I saw the splash screen again. Didn't even get to see the menu for SafeStrap. After several unsuccessful attempts, I finally accessed SafeStrap after restarting the phone from download mode pressing the volume down button. To make as much precious time as I had, I made a backup (although I checked enable compression which I shouldn't have but I didn't have a lot of space on my SD card) and made an advanced wipe cleaning everything except the SD card. I then proceeded to flash a different custom ROM (GoldenEye if you were wondering) and hoped that it was just a custom ROM error that kept giving bootloops. No such luck. The different ROM didn't even help. So I went back to SafeStrap and made another advanced wipe. At this point, I decided to flash stock firmware via Odin from this link (http://forum.xda-developers.com/galaxy-s4-att/general/guide-odin-to-stock-updating-rooting-t2926642) with NB1 base. I remember having flashed the non-rootable version successfully and restarted the phone after that. Got past the Samsung Galaxy S4 splash screen and went all the way to ATT splash screen but then it crashed right there. After that, I couldn't figure out the problem and I couldn't flash any more stock firmware (at least from that link) via Odin because I kept getting a fail notice. I asked this question on reddit and the responses kept saying that I may have a defective power button but it doesn't stay shut down and instead bootloops. Should I try to find a new GS4, get another phone or try sammobile firmwares next to see if there's any luck? I really need to save this phone as it is super dear to me. I'm at the point where I can cry right now :crying:
If you guys need any pictures or videos, I will be more willing to do so

I'd say try redownloading the firmware and make sure your cable is good, try a back USB port, etc. I'd guess the firmware files didn't download properly and so it didn't flash properly. Before you do anything though, try going into stock recovery and wiping everything you can from there.

Thank you for the reply. As for the firmware, where should I acquire them? The link I posted has only one firmware (NB1) and I cannot access stock recovery AT ALL. When I do, I can see the blue text in the corner "Recovery booting..." and then the phone restarts again. This is really frustrating

NB1 is the only one you can get, just try downloading either one again.

When you plug in the phone in Download Mode, does the blue box in Odin light up? If not, reinstall samsung drivers

N910F problems - emmc read fail/ flashing stock no longer boots the phone.

Hello. I had gotten this Note 4 phone which had a custom recovery installed on it but the rom seemed to be official, on 5.1
The first thing I did was go to samfirmware and flash a 6.0.1 rom, it went fine, phone was working properly. Then I got greedy and wanted to test a Note 7 ported rom. Flashed TWRP recovery and from within I flashed RamROM http://forum.xda-developers.com/note-4/snapdragon-dev/rom-sm-n910g-ramrom-t3400349 , I downloaded the one from post#2 , the N910F one that my phone is and after it flashed to ROM it simply stopped working. My phone no longer booted, was booting me directly into Download mode with emmc read error. I kept trying to flash the stock rom which I previously flashed and it would fail.
Afterwords I used Smart Switch to reinitialize the phone, writing my phones S/N and that failed as well but at least that made my phone boot into a different recovery where it said to connect to Kies. Once again I used Smart Switch and this time it was successful 100%. My phone even booted into the OS and was working, however, while using it, after 10 minutes the phone restarted into Download mode with emmc read error.
So all in all the phone is functional but it starts to lag and restart. Now I'm kinda stuck again since I've tried to flash the firmware I got from Samfirmware through Odin, it succeded but it just doesn't boot, it goes to Recovery, tries to apply an update and I get an error.
Is there anything I can do? I can't believe the emmc could've broken just from trying to flash that custom rom, especially that afterwards I was even able to boot into the phone.
Thanks for reading and I appreciate the help.

read this - http://forum.xda-developers.com/note-4/help/note-4-issues-t3453048
there are links to more threads related to your issue.
Short version though:
it is dying. install wake lock application, add it to start up and set settings to #4.
accept the fact that your phone will eat the battery faster and one day WILL die completely

Thanks for your response. Regarding the Wake lock application, I'm starting to look into it, I asume I'll have to be rooted. I'll try to recover it again using Smart Switch and then I can only hope I can install TWRP and still have it functional.
Previously when I was able to get it working with Smart Switch, entering the recovery messed everything up. It said it was applying an update and that got stuck.

no need to be rooted, just download, install and set it to autostart

I'll try it if I somehow manage to get the phone working again, Smart Switch just fails now midway through.

Is this the app you're talking about? https://play.google.com/store/apps/details?id=eu.thedarken.wl&hl=en
What exactly does it do?
I managed to restore it eventually with Smart Switch, it took quite a few tries, then I switched to my Macbook when I saw the app was available on it too and the 3rd try succeded. I only did it because I saw the 2nd try had the % much higher than the first.

yes, that is the app.
i've read it does not allow your phone to go to sleep mode.
drains the battery faster, but this is the only way to keep note 4 working without swapping its motherboard...

I have a question, my gf recently bought a note 4 and we may swap our phones and if we do, i'll flash CM and tinker with it because i find this phone very interesting, just a question, does this bug affect the N910C (exynos) model? Do i have something to worry about? Because the phone is warrianty protected and if it's the case, i don't want to break it. I hope someone will shed some light on this

Need help. Boot loop on J320P that was a friends.

Hey everybody, I need help. I have a J320P that is stuck in a boot loop, when it was found like this by my friend they came to me and asked if I could help. I have no information on how this happened other than they took a shower and when they came back it was like this. I have tried installing stock firmware 3 times to no luck. I might have an sd card somewhere with the backup for this phone but finding it would take some time so in the mean time I am turning to the forums. If anyone could help that would be amazing. I will provide more information and answer questions as they come.
Steps I have taken:
1. dirty flash of stock latest firmware
1. wiping the phone completely
2. Installing latest stock firmware
3. Still bootlooped

Not solved
So after triple wiping through TWRP and installing the stock firmware again it was still looping so i left to run to the store quickly and when I returned I tried powering it on and it loaded normally and I am still setting it back up.
Leaving the original comment. After coming home from work my friend said it had started doing it again, and it is. This time there was no root and no system anything messed with, does this mean there is a hardware problem?
