Send it back to Acer. They'll fix it, but you'll have to pay for shipping.

wow they ll fix it for free you think ?
they wont charge me 1000$ ?

Acer has a single pricing repair .The cost for this in the us.is.199.99 dollars. I have called them in the past. However I do not know about just fixing a bootloader issue. Something that they should give a way to the end user to do from there home.but then again they lock these devices to protect software rights of digital copyright and so on.
Call them but be honest as to what you done.They will figure it out anyway.
You can also contact sc2k here on this forum.He might be able to help you.
Good luck.

yes, I cant even boot. Dont see acer logo, android,
or hardware reset message "erasing..."
display stays black all time
doesnt vibrate
EDIT: just saw in my device and printer tab in sys settings, there is a device called APX. Acer Picasso USB Boot recovery driver
EDIT2: lol somehow i managed to get into acer download state with pbj20upgrade.
installing 3.0.1 now.
i think i was stuck in this mode and the devices waited for data or something
EDIT3: if anyone has the same problem try this:
install andoid sdk!
start pbj20
click next
turn out iconia
turn it on
if you are in APX mode (look in sys settings> devices and printer), youre good to go
it will check for versions
you get message: Connected ?
type yes
setup starts somehow

There have been more than a few members that have bricked their tabs, sent them back, and Acer has either fixed or replaced their units for free. Not sure wtf ER is talking about though?!?

Maybe I was a bit unclear.I was saying ask acernto fix it..
And I know from experience with acre they have a flat rate for repair.on any acer computer product.199.99.
I called them in the past about a main board in a laptop.
Then again when I dropped my tablet.Sorry for any confusion maybe I should go back to doing the dishes and looking pretty.
Boohooing

You interrupted the update...this is something you should never do when updating a devices firmware/bootloader and your tablet probably has an incomplete firmware/bootloader, as a result.
BTW: have you tried pressing VOL- and PWR, to load the recovery image: i mean if that would work at all, given your circumstances?

Screenproblems and a Customwarequestion...

I have a Viewsonic Viewpad 10s and some problems with the screen, I flashed at first the version Vegacomb 9n + Update 3. At the beginning it was wonderful but then the screen does not work properly. Even after a reboot did not care much. I went to ClockworkmodRecovery and flashes Honey Ice, it was back to normal. Some time later came the same problem, can someone tell me what it is?
The other question is, what ROM is to recommend the best? The tab is a Christmas present, I do not want to have again after 2 days because it is not reasonable ...
I am in a German forum, but there are not really someone who has the problem with the screen ...

I had the same problem with my Viewpad 10s with Vegacomb, HoneyIce and newer roms. One of the original issues was using it while it was plugged into the charger the screen became either unresponsive, or would randomly apply keystrokes that were not touched. Two people posted solutions, heating the outside of the tab with a hair dryer, and putting more pressure on the tab (squeezing the case) as you were touching the screen. I did find the extra pressure did help, but it was crazy trying to get the pressure just right. also noticed that screen worked differently in portrait and landscape mode. I often had to use portrait mode to slide the unlock across, while landscape would not allow the tab to unlock.
I decided to "downgrade" the rom to stock, it worked, then to modified stock, it worked but had some touchscreen inconsistencies, then to Corvus 5 rom, which I read somewhere solved other peeps touchscreen problems. Once I got Corvus 5 up and unlocked, I used his screen recalibration tool in apps and everything works perfect. I've been up and running for a month with no touchscreen problems. I even backed up Corvus 5, and tried Vegacomb and HoneyIce again. They worked for a couple of days, and then tab went back to touchscreen issues. I'm thinking it's a kernel sensitivity issue, but I'm know expert, and it's not happening on enough tabs for devs to take as a serious issue.
Hope this helps!!

you are one of the lucky ones man..i tried Corvus 5, true the method you described and still have the issues, well..actually i tried every single Rom and no luck.
I know it's mostly a hardware problem, the only differences in Rom's is the heating they produce, some more, some less..so depending on how bad your case is, you might find a balance and make it work for some time..or no time..
By the way, anyone knows if it's possible to disable the touchscreen inputs, from terminal, adb commands or maybe some app?

[q] no screen touches being recognized!!!

Hey XDA, Really need some help here, i'll bullet point my problem for ease of reading:
- 1st Nexus 4 bought from google had wi-fi issues so got replacement
- 2nd replacement nexus 4 was good for about 2 weeks
- randomly screen touches weren't recognized by phone so reboot fixed that
- got worse and more frequent
- now my phone does not recognize screen touches at all
- phone is completely unusable, power volume buttons work though.
- need to ask XDA before another replacement ///
WHAT I'VE TRIED:
- i was on stock, so i tried to reflash stock to get rid of gravity stock and stock kernel
- rebooting phone 3950280359283 times.
- cleared caches.
- asked google play support, they're clueless.
- problem was here before i was unrooted, on complete stock 4.4.2
- also wondering whether its a software or hardware problem. i assume hardware however.
- i still have warranty
ANY IDEAS?!? thanks.

Does a touch recovery recognize touches? If so, it could be a problem of your rom/kernel. Otherwise I think it's a hardware problem.

My screen works now. However it will still come back every now and then and is fixed by a reboot. When i made this thread it did not work for a whole day, so my device will probably breakdown again. When I use TWRP it does not recognize touches. A good decider. So i guess it is hardware?

I think so, but wait for another reply confirming that.

I'd say it's a hardware issue. Definitely get it replaced again.

Lmao. You're definitely right. It's really annoying they sent me another device with a WORSE problem. Gonna ask google for some sort of compensation. I don't really have time to fiddle with devices re-rooting them transferring all my data again and so on. Too much work.

[Q] [D802] Touch Screen uncalibrated after flashing

I've looked everywhere but haven't found a proper solution. I have an international D802 which after a lot of effort I was able to flash to KK but the touchscreen no longer functions properly - eg pressing one area would register one or more touches in anther area making it impossible to use the phone. If anyone has any idea to fix this please let me know. I have tried various roms including going back to a JB rom and the problem persists.
Thank you.

Even i am having the same exact problem which you have, i searched and didn't get any solutions yet.

Hi, I had an issue like this when I flashed the wrong tot file. It went away upon using the right one. whatever method you used, did you make sure to use the right files?

Anything worked for you?

I think we have following options:
1. Use mouse via USB otg to get to debugging mode to turn on adb than flash recovery and rom
2. Use mouse via USB otg to update the touchscreen driver via the hidden menu
3. Warranty
Can you get your device in adb mode?

Just managed to install recovery using autorec and lots of patience however touchscreen issues persist even in recovery (the touches are not accurate in recovery) so i think i will need to flash kernel as i think thats where the touchscreen drivers are.

Managed to flash CloudyG3. Still no good. The thing is that the touch is broken in CWM which means that its not the ROM, it's something else. I don't really understand the technical aspects but flashing Cloudy also flashes the kernel. Almost given up on this, too much time sunk.

I also had same issue and I flashed alot of different .KDZ and other custom ROMs too but the problem was always there.. so I went to the repair shop and he said that its a problem of eMMC chip so that needs to be fixed.. I have given the phone to him to fix it ...

Did you guys try updating the touchscreen firmware via the hidden menu? This is so frustrating, I've rooted/romed at least 5 phones/tablets and this is the first time Ive bricked something.

I am trying to go to the hidden menu and its not working at all .. So I will just have the touch replaced

I am not entirely convinced its the screen to be honest. I feel like replacing the screen does nothing about the software which control its behaviour. Just my 2c - if you want to go ahead with it perhaps get them to take responsibility - e.g., I replace the screen on your advice and if it doesn't fix the problem I shouldn't have to pay for the screen otherwise you might be throwing your money at a problem which we dont necessarily know the cause of.
Edit: Get a lgd panel not a jdi.

Ofcourse, if the guy is saying that after replacing the touch , it will be fixed and you pay 5000PKR then obviously i will check the phone before buying it otherwise i will not pay.. Simple

Scrolling issue

Hi everyone. I got my OP5 a few days ago and realized that the screen isn't working properly, apart from the jelly screen issue. Does anyone know if this is fixable or I need to replace the screen. I'll leave a video showing what I mean

I want to leave that as the last resource. Got it from another country, and sending it back costs a lot. Maybe knowing if the problem is the screen or the GPU can save me a couple of bucks

It has the latest version of OOS, but I'm starting to think that the problem isn't software related
