referb nightmare - Acer Iconia Tab A100

Hi just got one of these tablets from factory direct. got home, charged it and it was clear they didn't test it. the display is lite up weird were its hard to make out txt and there is alot of flickering like you would see if you watched someone use an old crt on television. not to mention, the tablet looks like its running on 256 colors.
it was supposed to be on hc 3.2 but when i booted it up it was on ics 4.03.
is this an issue were someone had it, messed around with it and possible screwed something up software wise? is this a driver issue or faulty hardware?
i tried factory reset, didn't do anything. I am downloading a fresh ics image and will try re flash with it but im not expecting much,
1 more thing, upon turning the unit on, the display is messed up like i mentioned above right from the get go.
can i save myself a 45 minute drive back to factory direct or do i go there and throw it at someones head?

URGENT help with boot screen, how to log it?

[Warming up]
I've been having problems lately trying to figure out the problem..
So, first i suspected the SD card, doesn't seem like my original 16GB card was the problem, because i bought 2 new 32GB Micro SDHC cards already, same problem..
[Now the problem]
80% of the times when i reboot and go into recovery and flash a couple of roms, or reboots in general, i for the most part get stuck in Bootscreen, if i try to wipe Cache and Dalvik-Cache, it sometimes solves the problem and 20% of the times i can get into the system, the other 80% of the times that i actually succeed into getting the rom to load up, i mostly get stuck there aswell, untill it reboots the phone, and im back at the imfamous bootscreen...
So, i've figured, is there anyway for me to log the stuff that is happening at the boot screen? because im curious to what the problem might be..
[The things i've done already]
Everything is formated as EXT4, and has been so since Mike introduced it with his rom..
i've tried Mikes rom, Unity, Honey roms, Coredroid, RCmix, all the same on all of them.
I always wipe my phone fully before i boot the rom, mostly with Mikes Super Wipe Script, but sometimes with the wipe zip mentioned from the Rom Dev explicitly telling me to use that..
I always let the rom boot 2 times before i start flashing themes and stuff..
Just going Stock rom doesn't help either, i've tried that aswell, no change.
I've cleaned the phone, from top to toe.. (brushed and cleaned with special liquid)
I've tried different Micro SDHC cards, 1 of em was a counterfeit card, the newest one works just flawlessly, i've benchmarked, checked for errors and even done a Bluff check on it, all working 100% nominal.
CPU running at 998Mhz, just incase..
[Ending]
So, does anyone have any suggestions?.. Does anyone have any way for me to get logs of the Bootscreen (as its a wallpaper, i have no chance in actually seeing what is happening)
Are there any ADB commands i could use to check errors in bootscreen? Any diagnostics tests?
Maybe even a way to refresh the Bootloader with ADB commands?..
ANY help would be greatly appreciated!!
You have some pretty serious problems here. Not that I could diagnose it, but it sounded like hardware related problems to me. Btw, here's the link about boot log you've requested.

Thanks man, very much appreciated!
I'll run some logs tomorrow and see whats up with the phone, i actually got the phone running optimal again with yet another fresh rom flash and it all seems to work, have only restarted the phone 2 times, as im afraid of restarting the phone and get stuck again..
If i do get stuck, im stuck forever, and have to try above mentions i've done before, wipe cache and dalvik-cache, sometimes this works, most of the times it doesn't, and i end up fully wiping a couple of times and reflashing roms untill it works.. (I know this might sound like an SD card problem, but its not, i've gone thrue this with a couple of programs)
Anyway, a thousand thanks for that link, will probably help me quiet some..

Aye, this phone i have in my hands right now has already been in for repairs before and they changed the PCB of the phone, got a new IMEI number and all that..
But i do have warranty left for it, but i have to iron out the problem before i send it in, don't wanna risk being sent back to me and i have to pay lots of $ for their trouble (you know how HTC 3rd party repair centers works).. Plus they might actually scratch my screen some more as they did when i last sent it in...
Well, i have another "minor" problem with the phone aswell, not sure if its my phone or a general new cosmetic problem occurring on phones sent in for repairs, as i haven't noticed it on my earlier phone (Well theoretically the same phone).. Is that when i look at the screen in pitch black moving screens, i can see a distinct line going from Top Right to Bottom Left corner, and the Top Left side of the screen is black, and the lower right part of the screen is black/grey, you can see the difference, but not noticeable when your actually booted up, only in the Bootanimation part is it visible, i've tried different Bootanimations and everyone that has a Black background has this cosmetically problem.
Aah crap, Wall of text..
Haha just gonna add that i installed both apps you mentioned earlier, and the phone feels more like a Dev phone now, but anyway, it all worked great, not sure if it logged anything yet, didnt find anything in the app yet if it does..
I noticed something strange though, Gsensor Enabled, then right before bootup, Gsensor Disabled..
Have no idea why it does that, have no problem with Gsensor though..
Edit:
6 successful restarts!! That's something new!
I have no idea why its behaving this good.. Well time will tell..

[Q] Screen's gone fuzzy and weird - Solved

My Captivate Glide's screen does this whenever I turn it on:
I didn't drop it or get it wet, it just started doing this randomly.
I live in the UK and ordered the phone unlocked over eBay so I can't take it into an AT&T store, sadly.
Do you guys know if there's anything I could do myself or anything someone more experienced in repairing mobile phones could do to fix the screen?
This is bearing in mind that not many people over here have seen one of these phones though.
Any help would be massively appreciated. Thanks guys.
you was using still GB right? just flash ics via odin, with one click or with a tar file
This is UCLH2 without one click
http://androidromupdate.com/2012/09/...ota-stock-rom/
And here is the latest version with bug fixes (like keyboard light)
http://androidromupdate.com/2012/11/...ptivate-glide/
and there is for one click
http://www.androidauthority.com/captivate-glide-sgh-i927-att-android-4-0-4-ics-uclg9-leak-110365/
i think that only one click wipe your internal storage. but is the bes (in my opinion). try it, dont have anything to lose
No, I already updated it to ICS. Should I reinstall it? Will that fix the screen? How will I manage to do it with the screen all messed up?
if you can put in download mode, then you can. Its weird because i only see that problem with GB. Put in download mode and then reinstall
I just tried putting it into download mode but I get the exact same thing.
Thats weird, the problem is weird because it never happen to me in download mode, maybe you can try it without battery, or let the phone without battery a couple of hours, etc.
Dont Know what you cand o, because if you cant enter in download mode, you will be no able to flash ICS
Hrm... that purple splotch in the bottom left of the screen doesn't look so good... Almost appears as if it had been dropped on that corner at some point in the phone's history. I am tempted to say that is a hardware issue, though. Reminds me of when the flex cable for my laptop's display started shorting out many years ago. Might be repairable, but, might be a costly repair depending on what all needs to be replaced. I can't imagine replacing the software on it will do much, though, sorry to say. You could give it a shot, you can verify if your phone made it into download mode without the display by loading up odin and seeing if it detects under that, and then running the one click install (or any other since you'd have odin running anyway) but I wouldn't expect much.
If you're not getting the Samsung/Rogers logo screen, you're done. Either the screen is physically damaged, or the bootloader is corrupt. There's no saving that one, sadly.
yes, try what Artemis-kun say. put in download mode and connect, and see if odin detected. Or maybe just turn on the phone and wait a little, then try to call to your phone, if the phone ring or appears to be on, then is a hardware problem.
But try what Artemis-kun, maybe you have luck
PD: now i see better the image and it seems little different from what it happens to me. if you turn on, inmediatly happen that? or screen banish slowly?
AW: [Q] Screen's gone fuzzy and weird - need help please
There should be a cable, connecting the hardware to the display. Maybe it loosened, you should check out the video of a guy tearing his glide apart, hopefully youll find something to repair there.

Hey guys, you'll be glad to hear I finally fixed my Glide by installing a new screen assembly from Repairs Universe.

[Q] SGT3-7" Boots up w/no logo and no pic (updated to kitkat 1 day previously)

Title pretty much says the basics.
Details however are as follows.
SM-T210R, Have had this unit for about a year, always been in a case, never dropped, not a scratch/dent/ding on it and I use it every day.
Past couple weeks I was getting update notification from Samsung, I'd always put it off till I got home then not bother when I actually got there.
Finally, a long weekend for me.. I let the update run its course, No problems (500+MB's) And I believe it was upgrade to Kitkat from Jellybean.
Can't remember the exact version details.
Soooo, I use my tablet throughout the day everything seems to work great NO problems at all.
Notice my battery is down to like 20-25% and plug it in (Original wall charger and cable)
Go to get it the next morning, open the case expecting it to flash and display my lock/swipe screen, Nothing.. Not TOTALLY Black, you can see theres still a glow.
The screen still responds to touches ( I can swipe to unlock it and hear the sound)
I tried to reset power. Nope nothing except I can hear the startup tune.
Tried hard reset, nope same thing.
Tried every button combo I could think of or contort my hands/feet into.. Nope no joy.
Hit the internet... read, read, read, read, watch videos, watch more videos..
Ah-ha take the back off, disco battery, wait, replug and voila.
Nope.. not the issue
Different milliamp chargers, nope.
WTF??
Normally I'd think I did something to it, but I did nothing that I hadn't done at least 200 times already.
I'm convinced Samsung F'd my tablet w/their update, not only that but my $1200.00 drone sits idle over my holiday because my vision app resides on my sgt3.
Ideas?
My best solution so far...
Well its been like 2 days since my sgt3 lost its mind.
Found a solution.
EVGA - Tegra Note 7. (No hyperlinks allowed for me....Yet)
nvidia.ca/object/evga-tegra-note-tablet
DAYUMMMMM.
This thing blows my SGT3 right off the map.
Still would like to find a REAL solution, there's alot of configurations on my SGT3.
But in the meantime I think this'll keep me almost content.

Just download odin and the firmware for you country and flash it if it gets stuck at the boot get in recvory and wipe and flash once more works a treat
sounds like a bad flash i never let over the air upgrades there trouble always use a pc

Thanks Jason, I've not messed w/flashing the firmware through pc on this thing yet.
I've done it w/psp's, motherboards, routers etc, but never w/one of my tabs.
Just to confirm... I dont need a display on my tablet to flash it w/Odin?

No, you don't need the display on your Tab, you just need Kies and Odin on your PC.
Place your Tab in Downloadmode(VolDown+Home+Power,release All buttons when you see the warning, press VolUp) then choose your PDA firmware in Odin(Obtain firmware from SamMobile) an hit start. After this boot into recovery and wipe/factory reset your tab if it's not booting!
Good Luck

Hey Daniel, Thanks for the info.
I found Odin was pretty easy to flash with.
I've tried 4 different FW images for the GT3-7 and taken the unit (almost) completely apart w/the exception of removing the actual digitizer and the lcd.
Same results after each install though.
It boots, plays the boot sound, but no display.
I guess next step is removing the screen.. After that I don't know what to do except possibly getting myself a lcd replacement..
Just might drop it off to one of the local shops and get them to do it that way I won't wind up paying for something and f'ing it up.
No joy w/my sgt3..

Even went so far as to try Kies to do the last one.

[Q] Bought Refurb Tab S 8.4... odd booting issues

Generally when I get refurb, I have pretty good luck, but perhaps the forces that be are saying I shouldn't have one. When I first ordered, I got one with a dead pixel. Couldn't fix it, so I sent it back. Just today I got my replacement. I was pretty excited since the tablet looks brand new (still has most of the plastic on it around the edges. I charge it for a bit, turn it on and....
It played the Samsung startup music, but the screen stayed black. Didn't show anything. Keys lit up like they should, everything sounded normal, but was just black. For a while nothing happened, then finally the screen came on. It seemed to act normal from there on. Thinking nothing of it, maybe it was just a glitch, I took a few OTA updates. Every time it reboots, the screen issue comes up. And while it was updating, it didn't show the android updating screen. Also, I can't get it to go into recovery. Perhaps I actually am, but the screen is off so I can't see. I've searched and can't find anyone with a similar issue. Since this is my second device, should I just send it back and ask for a refund or is there something I can do to try and fix it?

Well to force reboot, hold and press power+home+volume up and down until it reboots. Have you tried to also factory reset in recovery?

I was trying to say I can't get into recovery. I don't know if it actually is in recovery with the screen off, or if I just cant get to it at all.
Additionally I just tried a KIES update, and it did not take. When I plug into KIES it says the same update is available even after I just updated it. Just now doing a software factory reset. So far no change. Unless someone can provide me information on how to fix this, looks like I'll be sending it back.
You will know if you're in recovery if you type 'adb devices' into a command window with the usb cable attached.
If it returns a set of numbers you're in recovery.

[Unsolved] Screen issues

Video of the issue: https://www.youtube.com/watch?v=XzIx9SHj6MQ&feature=youtu.be
According to my sister it has always had the screen "artifacts"as shown in the video where certain pixels are the wrong colours (which apparently never set off any alarm bells in her head... ). But apparently the screen and device stopped responding correctly a while back which i have been able to find out can be fixed by taking the back off the device. I can not use the recovery on the device since it just displays multicolored static on the screen, same thing happens when the device is plugged in to charge while powered off. I told her to get all important data off the device and factory reset it so the device is all at factory defaults to rule out software issues. After that didn't work i took the back off the device to check to see if the screen was connected correctly and to see if there were any obvious issues such as the cable being visibly damaged or disconnected etc.
Image of the issue when charging: http://i.imgur.com/Kat1RoC.jpg
So everything is stock on the device. It has never ran anything but official updates directly from Google.
The device is out of warranty and considering the cracks on the corners of the case i doubt Google/Asus would be happy to fix the device out of warranty without it getting expensive. It would be nice to fix it if it is possible or financially viable.
Any ideas and suggestions appreciated!
Have you tried a factory reset? If not, have you tried reflashing a stock rom, wiping everything?

It has been factory reset. I have not flashed a new ROM to it.
I have actually fixed that issue by putting some padding in to prevent the cable from flexing so much inside the case. So the device now functions as an e-reader and web browser. But it still cannot play video or cope with scrolling through images and so on due to the tearing. It gets worse the more that is updated on the screen. This may still be a cable issue.
I would flash a new kernel and ROM to the device but download mode doesn't work since no computer can recognize the device. In download mode and recovery the screen shows the static as shown in the image meaning i cant really use it easily. Since it is still running stock recovery i cant just flash a zip file, since download mode doesn't work it may be difficult to do the above.
But i only have experience with my own Galaxy S2 which runs custom everything. So my experience is with Odin and CWM, so i am not familiar with download mode for other manufacturers.
The second image, I know this. I was fiddling with the ribbon cables one day and I also got that distorted screen.
If it appears when charging, sounds like...the cable is not grounded or something and the signal(to/from the ribbon cable) is being distorted. But that is just a guess, it could be anything.

Its not exclusive to charging though therefore i dont think it is power related. It happens every single time the system displays something on screen outside of Android. So the charging screen, recovery and download mode are all displayed as that.
Have you tried fiddling with said cable when you get the distorted image, in an attempt to perhaps fix it? it's odd that it appears with system messages. This sounds more and more like a true hardware issue(a defective unit) than software or a "simple" ribbon cable problem.

Not while it displays that image. But i have unplugged it and plugged it back in and nothing has helped.
My theory at the moment is that the cable is damaged meaning when the device tries to completely update the screen data goes missing and it struggles. Since videos dont work at all while the android flappy bird clone works flawlessly since it doesn't need to send as much data to update the screen due to the solid background colours and so on. But there are still holes in that theory, for example the issues become many many times worse when the device is in landscape mode.
So as far as i can tell it could be anything from heavily corrupted software to broken vram and anything in between including broken cable (since fiddling with that has fixed a different issue, perhaps its related) to the displays RAM for storing the previous screen update being broken. I can't tell.
Defective VRAM is also a possibility.
But I am not aware of any tool(for Android) that would allow for direct memory scanning of the VRAM. If you end up deciding the tablet is a goner, and want to buy a new one. I'd advise against another N7, it's already old, and the bugs are not worth the hassle.

Yeah, im not aware of any either. I have also been through all the relevant debugging tools. Telling the screen to flash on update actually made the device function much better (where it flashes pink on each update) it stopped the issues from being serious. But lets face it, no one is going to want to use a device with that debugging option left enabled.
