[Q] Boot verified failed and APX driver problem

---

Hi!

I have tried to flash unlocked bootloader V3 from civato's guide, and I could not pass step 6 (flashing bootloader with nvflash or blacthund3r's tool). None of this method didn't work (Nvflasher didn't flash anything, and blackthunder tool was stuck at formating some partition (can't remeber which one).
Last successful step was flashing ICS rom (full leaked version of 1.031.00).

After that I could boot up, and rom worked all fine.

But, after that, I got my self in trouble.... I pressed Vol- & PWR, tablet did his thing, and when reeboted, I got stuck in Acer logo screen with red writing "Boot verified failed"

I understand that I have messed boot somehow... And to fix this i have to flash new bootloader through nvflash and apx mode. I tried to put update.zip on sd card, but it didn't helped (I still get boot verified failed)

Here, I got another problem. When I have connected tablet in apx mod to pc, i got message "driver not installed". Now, in devices I have "unspecified APX device".

BTW, adb doesn't see my device?!

I hope that You guys can help me with these problems, so that my tablet is operational an running again.

Thanks in advance!

I have the same problem but I can not find the v3 bl and CWM Recovery Package to flash with the apx flash utility. If you find them let me know.

This what you have do:

Your recovery is borked so u have to put a new one on there, the best way to
go about doing this is to:

Download the V3 AND CWM Recovery package and apxFlash that.....Done!!

your need to flash the WHOLE PACKAGE b/c ARI reports yr BL as plain old stock
You cannot replace the failed recovery with CWM with the plain old stock BL!!
You have to flash the patched BL as well, so again
You must flash the whole pckg just like in the guide OK
if later u want the stock recovery back u can use ARI to do that but after the apxflash!!!

Thanks for your replay! I'l try to do this and hope it will work...

By "WHOLE PACKAGE" you mean unlocked bootloader and CWM? Or, something else?

Check this thread for V3 and CWM.

Yes "WHOLE PACKAGE" unlocked bootloader and CWM

The tread you sent me I do not know how to use the nvflash never works for me.

I have been trying for 3 days and no luck.

Let me know if it works for you or how you make out

Hi!

Yes, I have dl the drivers from Acer site and installed them. But pc only recognize tab in APX mode. And adb doesn't see my tab.
Every method that I have tried (APX flash tool and nvflash) hangs at some part. APX flash tool hangs at "Flashing bootloader EBT - stage two, and nvflash hangs at formating partition 4.

Hi, I´m having similar troubles to get acer drivers working on windows 7 32. I installed newest acer web drivers, ADB works OK. When I get to apx mode I need to manually point to drivers, I have an APX driver with a sign and turns to Acer Picasso USB Boot-recovery driver. The problem is that not any of the tools sees this as a connected tablet in apx mode (afterota or apxflash).
I am doing something wrong? I know a500manager shows me the tablet is in apx mode "please install drivers" when i get APX driver with Sign, after installing the driver manually it just doesn´t show connected anymore.

thanks

Download and install the Google USB drivers.

Google.... Android USB Drivers, and you should get the page for the Android SDK with google drivers.

In Apx mode, go to device manager on your PC, and manually install the drivers. Don't let it search automatically, do it manually. If you get a compatibility warning, ignore it.

Should hook you up with normal, ADB and APX drivers.
