ok lets try this out,

power off your tab, hold the volume down and power button, continue holding both buttons until the tab load the acer logo. are you coming into recovery?

if so use the volume to go down to advanced, then wipe dalvic cache, then click yes, it will take a second or two. when the wipe is complete try goin back in the options to find reboot system. with any luck it may fix you

you should see a screen saying optimizing apps .

hope it helps

scratch that^^ read your post abit more in depth and im assuming you must have recovery and have wiped dalvik while doin the above,.

try this method to install the v7 or v8 bootloader its the ics version and unlocked/patched im using v7 right now after i got a bootloop and error saying bootloader unverified.

http://forum.xda-developers.com/show....php?t=1622425

the area you wanna concentrate on is after step 6 do read the entire thread though and remember to always have your cpuid!!

ALL REPS GO TO CIVATO /BLACKTHUNDER THE A500 DEMI-GODS
Note: please read everything twice before performing any dangerous operations on your tab i will not be held responsible


STEP 6 INSTALLING ICS BOOTLOADER
Automated flashing tool

USING blackthund3r ATX flash tool , It makes it all a little easier !

You need help on this ! Here is a walk thru!

-download the APX-FLASH-Tool & Manager

-Download one of the V8 unlocked bootloader apx flash packages combined with a recovery of your choise.

V8-pubA50._public_recovery.a500apx
V8-Thor_1.7.3_recovery.a500apx
V8-TWRP_2.1.3_ICS_recovery.a500apx
- Firts you do the Steps 1-2-3- 4 of the main guide !!

-1-Reboot your tablet and make sure on your tablet: "Settings" -> "Applications" -> "Development" -> "USB debugging" switch on.

-2-Now start the "A500APXFlash.exe" , the tool will start .

-3-When it askes for your SBK you need to type it in , the v0.4 APX flash tool will give your SBK automaticly !!

-4-Now you select "Use an A500 APX Flash Tool Package.(.a500apx)

-5-Select the package that you want,(you click on the right arrow to continue)

-6-Now you can select "Manual Method" or "Automatic Method". (I always pick Automatic)

-7-Click on "Enter APX Mode" (now it will do his thing)

-8-When it says "Done! press to run again" (even if it says on the bottom of the app "no apx mode devices are connected") you click on the right arrow to continue.

-It will ask if you are ready (click yes if you are)

-Let the app do his thing and wait !!!!!! Until it says "Done! Press and hold power to switch off then power back on!"

Optional A500MANAGER
What does it do :
· One-click APX Mode entry
· One-click Recovery Mode entry
· One-click fastboot entry for patched bootloaders
· Instant logcat viewer
· Instant dmesg Viewer
· Function which dumps the dmesg to a text file on the desktop
· Serial number extraction to make SBK calculation exponentially easier
· Links to ICS Root, A500 APX Flash Tool and two download links (Acer and my mirror) for USB Drivers
· Shows what mode the tablet is in at the bottom

erm well mate...u dont, you enter apx mode manually with the reset button and power button.

like i said read the whole thread buddy

Gotcha mate. So APX mode is like USB dubugging right?

Time to read.

Ill post back.

im not the best but from i know and understand =

apx mode is like the base programming/flashing state for making changes to your tabs guts/ loading software/os,.

usb debugging is for locating/extracting/uploading information to a system with already loaded software/os

you would need usb debugging to let the flashtool automatically set the tab into apxmode/ as doin it manually can be a hassle, but since you cannot turn usb debugging on to use that feature of the tool you should be ok to manually power into debugging and continue with the guide

tip: i learnt the 1-week till 3am way, you must have the usb plugged to enter apxmode.......or is it the other way around? or is it the charger? lol i cant remember srry

note: yes bruuu read, read, read, these steps are very dangerous to your tab if performed incorrectly. check everything, even look further down the threads to see what problems and solutions others have run into before flashing anything.

let us know how your doin and hopefully we're have it live n kicking again soon

ok im in APX mode. i start the manger and it asks for the SBK.

If i red this right the tool should get the sbk for me?
-3-When it askes for your SBK you need to type it in , the v0.4 APX flash tool will give your SBK automaticly !!

but the tool does not give me it?

-STEP 3=Now go to vache's site to get your SBK

you put your cpuid in and it gives you your sbk

these steps are further down the page (i know its set out weird)

How to get my CPUID ?

On HC Rom or HC bootloader (3.01) or you got a old nandroid backup do this to get your cpuid
-You can find your "cpuid" in one of your "nandroidbackups" that you made with cwm (look on your external SD/clockworkmod/backup=uid.txt ). It's the uid text you are looking for.
-Or when you connect your tablet and type in adb devices in cmd you get your cpuid
-Or usbdeview see more info here , thanks to dibb_nz


ON ICS ROM or ICS booloader (0.3.11 or 0.3.12) do this to get your cpuid:
Or you Install and launch Android terminal app on tablet. Run the following command: dmesg>/mnt/external_sd/dmesg.txt
Open up dmesg.txt (will be stored on your external SD) and look for androidboot.serialno. That is your CPUID.

Or try the following to get your cpuid (thanks to japinder)
-Reboot the Tab & just use the command 'dmesg | grep androidboot.serialno' (without quotes).
It displays the cpuid there & then. No extra lines, no need to save to file & then search. If the Tab hasn't been rebooted in a while, then the line containing 'androidboot.serialno' entry is lost/overwritten, so it won't even be there in the 'dmesg' output. Running the above command after a fresh reboot will always yield the result in an easier way.

so when you got your cpuid go to vache's site put it in and get your sbk, u can use the relative step in the thread to check your sbk is correct if you feel the need.

Enter it into the a500flash tool download a500
flashtool

click arrow

then select a ".a500apx" package u can get one here : skrillax BL's
Im using the v7

click arrow the tool should then do its thang! when it says pass/complete/get me a beer just restart your tab and it should be good to go.,


these are the steps i took on my tab when i had a unverified bootloader error and it fixed it all for me,... but i can not be taken responsible .....your tabs not working anyways so eh lol

Thanks for all your help.

Looks like its just a brick as i have no backups what so ever and it's never being rooted and it won't boot what so ever


Thanks mark
