Question with regards to Plants vs Zombies 2 and the blackscreen issue.

On previous builds CM11, I was able to use Resolution Changer Pro to change the res. to get the game to run.

On this build, none of the resolution programs seem to change the resolution (Tried NOMone Resolution Changer /Screen Size and Density). Resolution Changer Pro actually causes the table to reboot about every 20 seconds, once you try to change the res.

Any ideas? I believe the correct resolution is 1280X752.

Anyone actually pull it off?

Hello,

since the first version of Android 5.1 I have the same problem. All 5.0.2 work well without problems, but flashing 5.1 get me stucked in a bootloop with acer Logo. Obviously I wiped all data, I tried different Recovery including up2date CWM (with LVM, of course), I tried flashing by recovery and by flashify. I would use flashboot as well, but my USB Port is "slightly mad", seams to be common as I had the same problem with the device before I changed the mainboard two years ago (Burnt the first one with a 12V charger - interesting, with sparks and smoke and some strange display output like old tv going crazy but not recommendable.). It needs about a million times to get connected and after that it drops the connection randomly. No big issue, as I have bootloader unlocked and CWM working. Anyway, it's working flawless under Stock and other Roms - but CM12.1 is just denying to boot at all. So, I don't know what might be the reason. It's not that I depend on cm12.1 but I'm curious. What can be the problem? What's the reason to fail on this specific device?

Bootloader is JB, Installing works without problem, LVM activated, all storage reset, no errors reported, everything wiped - is there anything more I can do? Or it's just CM12.1 is out for the world beside me? Any help appreciated -

Greets, BL

Hi Shreps

Is this version (	cm-12.1-20150902-UNOFFICIAL-a510	9b143c7168fb60011225b94b5c45bed7	CM12.1 - Zkernel) from your site (acer.shreps.fr) is a continue of this project? On first page last version is 22/07 and this one is from 02/09?

Hi there,

thanks for the work on this image.

I just flashed my A511 and it worked very well and easy.

Just one things confuses me: TitaniumBackup and all other complain about not working "su".

Files are located in /system/bin/su and /system/xbin/su.

If I execute them within a terminal nothings happens.

Any hints for me?

Does anyone know if I can easily downgrade from cm12.1 to cm11? I will switch to another tablet (that runs cm13) and want to hand this tablet down within the family. But with 12.1 there is too much hassle (closing each app after use) so I want to put a more beginners friendly version on it and cm11 was always very stable. Will it be just wipe and install or more difficult?

(27cc48411b1755a8569398a3e8d678d9)

Here is the build, I can't test it, so I hope it will have no issues.

BTW, has everyone noticed, I'm not active on this device anymore. The reason is simple : I gave my parents my A510 and I moved on some new devices.

It means there will be no new development on my side for this device.

That was a great adventure with you guys, I hope you enjoyed your tab until now ^^

PS: I tried to compile CM 13.0/Android 6.0.1, but it requires many Kernel upgrade. We need a developer able to upgrade our t30 kernel from 3.1 to 3.4 and then apply all security/SeLinux patches required by MM.

That's how grouper got CM13 running.
[Acer Iconia A700 and A510] GhouLinux:
Hi Shreps, very sad to hear this. We have three of these fabulous tablets in active use here in my family. I'm going to give the new build a test run soon. Are you really completely sure that your parents should be endangered by their software getting older and older?!? ?

CM13 would have been great, but from the discussions I saw on XDA (for the Samsung Galaxy S5) this would be more than a full-time job for a single person...

Thanks for a great and interesting time...

GhouLinux

Update: cm-12.1-20160130-UNOFFICIAL-a510 needed some time to flash and some time to boot (~12min), but behaves very friendly afterwards. Up to now no problems found. If something shows up, I will update here...

Actually he made perfectly stable CM11 and CM12 and even if we keep it as it is, tablet will remain fully functional for a lot of time.

According to my experience developing CM13 for A510 actually does not make much sense - on a daily base is CM11 much faster for A510 than CM12, so I switched back.

No for now, it's just for experimental testing, I will open a thread only if it's usable (which seems to not be ok for now).

Tried the flashlight way yesterday. It only works on startup. When A700 went to black screen or restarts, then it wont work with flashlight. When set brightness the manual way, then screen also turns black cant say when. but it has`nt run more then 5 mins without problems.

When the massage "App not responding" comes, the background turns black and then i got flickers wich shows the backgroung for milliseconds. It restarts after short time. Then it offen hangs on reboot. I have tried to set min and max cpu freq to lower values, but crashed again.

It should work without problems but don't blame me if your tab is hard bricked afterwars.

fastboot oem unlock

don't flash this bootloader it bricked my a510 !

i was on ics bootloader and cm 11 from shreps... i flashed cm12 + gapps (mini) from twrp bigsystem... and was stuck on acer logo

i tried to flash jb bootloader and after reboot... i only had one choice... read "boot image verification failed" and no way to use recovery... no reset worked...

i successfully activated fastboot and do the following steps:

- fastboot oem unlock

- fastboot flash recovery recovery-cwm-shreps-6.0.5.0-a510-lvm.img

- fastboot flash recovery a51x_twrp-2.7.1.0_bigsystem.img

- fastboot reboot-bootloader

- fastboot reboot

and now i have cyanogen boot logo... but it's long and long... don't know if it fully worked but i'm not stucked at this ****ing message "boot image verification failed"...

Edit.1

: Passed the CM logo... Now on optimizing... Yeah dude... do your optimizations...

Edit.2

: Passed optimization and rebooted... hope it's stable..

Edit.3

: After reboot... still optimizing... strange...

Edit.4

: Rebooted... seems to work... brightness bug seems here...

Edit.5

: Seems laggy and can't access recovery at boot... maybe a full factory wipe is needed now

Thanks for the feedback I'm glad that it worked? you're both on jb-bootloader now or? and sorry for not having in mind that the bootloader needs to get unlocked after flashing but be happy it's only the data you lost and not the whole tablet what could have happen...

You see a small line at the top with jb-some numbers at the very first screen? A factory reset from recovery is needed when coming from cm11 no way to avoid it ;) but should already happened as you did oem unlock the bootloader...

Ah OK I thought it's normal behavior that unlock formats data partition like on other devices. But you're on the jb bootloader right? Titanium backup shouldn't make problems though but avoid restoring system apps...
