[Q] Boot verified failed and APX driver problem - Acer Iconia A500

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.

boot verified
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.

To get back to stock you'll need to run an official a501 EUU - theres a thread in the dev forum by blackthund3r with a list of official Acer Roms -
you need an "EUU" AND I hope you have saved your cpuid from using afterOTA - you can't do anything now without it

Well, that is good news, you're halfway there
This tutorial will give you some background on rooting and installing CWM http://forum.xda-developers.com/showthread.php?p=35500631#post35500631
But now you have the v8 and access to fastboot the first thing you should do is to hook your usb cable to your pc and run a command prompt from the fastboot folder (if you need help with doing that have a look in the cpuid guide linked in my sig). You want to wipe /data and /cache and then immediately flash an ICS custom rom...civato has a thread with official acer stock roms that will run on the v8 or you can choose a full custom one.
You should already have a custom recovery on your tab, if not, use fastboot to flash one after you did your wipes...then boot to it and flash your rom not an update.zip
i have hook the usb cable but i cant write somthing on the cmd
its noet working, i want to install CWM this was verry easy to use.
I dont now why its verry difficult to root and install a custom firmware on a Acer Iconia A500.
I have olso a Samsung galaxy tab, this was veryy easy to use after 3 minutes it was rooted and installed the CWM.

First to thanks to dibb_nz, civato, Moscow Desire & Heisenberg.
I have installed Skrilax CZ bootloader V8 on my TAB ( after six month trying )
Then Installed: CWM recovery v5.5 thor2002ro rev.1.7.3
showing: kernel 3.1.10-digetx-thor-4.4micro
Bootloader: 0.03.14-MUL
Active boot partition 1st boot partition set as default.
Not running HC bootloader, itsmagic not needed.
As per your instruction on (Skrilax CZ bootloader V8) wipes all the /data and /cache using fastboot method then reboot and after going to CWM recovery flashed Civato official acer Rom Acer_AV041_A500_1.041.00_WW_CUS1 from here http://forum.xda-developers.com/showthread.php?t=1633907.
But again my Tab is stuck on Skrilax CZ bootloader V8 bootmenu.
now help me what to do.

[Q] Who can help provide a motorola official update.zip file?

My milestone 2 is completed bricked and can't be recognized by PC. But I can log in the official recovery screen. I have downloaded a update.zip file from a link (not sure if it is an official link, as I can't find it through Motorola website). It prompted "signature error" when installed. Not sure anyone can provide an update.zip file, so that I can try if I can save my Milestone2. Thanks in advance!
as long as you can enter the stock recovery. your device isn't bricked. did you try to do a full wipe in stock recovery? did you try to use another usb port in bootloader mode? sometimes you get a black screen in bootloader mode, but you pc recognizese your device very well. did you install all drivers on your pc?

1. I have tried full wipe, but didn't work. The machine reboot again and again;
2. I have tried another usb port, another PC and even another operating system (win7 and winXP), also didn't work.
3. I am sure I have installed the drivers, as PC can recognize my phone when it is OK before;
As I can only entered the official recovery screen, I think I can try if it worked when I update with an official update file. Anyway, thanks for your suggestions and reply!
hi,guy.i think you should do the curect usb driver for your pc recongnizing first. than choose a ringt bootlaoder offical ROM. curse your phone can login the rockrecovery screen means its ok! isn't?
I think the only way for you to get an update.zip is with another milestone 2 running froyo, that way you can update it via OTA, and before the phone reboots, take the update.zip from the /cache partition.

Acer Iconia A500 bootloader issue

Hello,
I read a lot of threads but I'm really tuck...
When I power on my Acer Iconia A500, I have this error message : "Secure boot: image LNX checksum fail!"

When I power on my tablet in recovery mod I don't have this error. My recovery it's TWRP v2.4.4.0 (Team Win Recovery Project).
I have not my CPUID, so I downloaded Afterota and install the official driver Acer.
But when I plug my tablet, second step "Usb Connection" I have this issue : ERROR - connect usb cable and enable usb debugging"
But I can't enable usb debugging because my ROM is fail...

I think I brinked my phone. Please help [SOLVED!]

Hello. I tried downgrading from the latest ASUS firmware to Android 6.0.1
I used this tutorial to install the raw firmware: http://www.asus-zenfone.com/2016/12/asus-zenfone-3-raw-firmware-and-asus.html
Went all the way to the last step when the app hanged. ASUS Flash tool went all the way saying
Code:
Run flash image script ...
It was hanged there. And as per this video, went all the way to the end where it showed the "code bar" on the right (https://www.youtube.com/watch?v=P8xg7A-P7Ak)
This is when the "Android" uninstalled driver showed up in Windows. This is under "Other devices - Android". I tried updating this driver using the ASUS_Android_USB_drivers_for_Windows found here: https://www.asus.com/Phone/ZenFone-3-ZE552KL/HelpDesk_Download/ but it wouldn't install the drivers.
Note that I used these ASUS USB drivers to get the ASUS ADB Interface installed. As per the tutorial I showed in the very first paragraph, I never got the "ASUS Android Bootloader Interface". This is what I think this "Other devices - Android" is found under Computer - Manager - Device Manager.
Most tutorials on the internet shows that the "ASUS Android Bootloader Interface" should be installed using these drivers found on ASUS website, the ASUS_Android_USB_drivers_for_Windows.
Now of course because I unplugged the phone, it will continously stay on the Android splashpage showing the loading circle infinitely.
As a last attempt I tried installing the "stock", not "raw" firmware (the one I wanted to install WW_13.16.5.49 but ASUS would not let you downgrade using the recovery "power+volume down" and using "Apply update from microSD card". It would give the
Code:
Warning- No file-contexts. This package is for "ww-phone" devices, this is a E:error in /side load/ package.zip (status 7) Installation aborted.
)
Well, after it brinked, I tried it again and this time it DID install WW_V13.16.5.49. Was succesfull. But after the ASUS splashscreen it's still stuck in the booting process.
I am very sorry if my post is convoluted but I tried explaining everything I did. Any way to un-brink it? I think maybe if I figure out how to properly install the ASUS Android Bootloader Interface, I can try again ASUS Flash tool and install the raw image and maybe that will fix it?
Please help. Any questions if my thread is too confusing, please let me know and I will answer it. I can't even turn off the phone. While it's stuck into the load splash screen, if I press the power button it just restarts, not turn off.
I still have access to fastboot (pwr + volume up) or recovery (pwr + volume down)
EDIT: Phone won't get recognized anymore in ASUS Flash Tools. Serial number won't show up to select
Factory reset and delete cache/dalvik through recovery and post back. It'll take 5-10min to boot up after that. You should always delete cache/dalvik after flashing.

Thank you, this actually worked!!
Aaaand, it's actually on the version 13.16.5.49!!!! THIS IS EXACTLY WHAT I WANTED!
So apparently by brinking my latest nougat 7.0 update from ASUS via the ASUS Flash Tool trying to flash the .RAW 13.20.10.137, the standard recovery system (power+volume down) allowed me to install the 13.16.5.49 version. Then I assume remnants files didn't allow to properly boot, and your idea to wipe cache and factory reset fixed that!
What is so great is that I was scared that because the .RAW firmware was newer than the version I needed (13.16.5.49), I wouldn't have been able to install it. It was the same problem initially, when I tried to install 13.16.5.49 directly via recovery over the latest nougat 7.0 version from ASUS, but it was giving me
Code:
Warning- No file-contexts. This package is for "ww-phone" devices, this is a E:error in /side load/ package.zip (status 7) Installation aborted.
I think this error was due to the fact that ASUS won't allow older firmwares to be installed over newer ones, as per their webpage
https://www.asus.com/support/faq/1009748
Code:
You can not change the SKU from one to another, e.g., WW -> TW, and also can not downgrade your firmware, e.g., V2.20.40.13 -> V2.19.40.18
So in the end, what allowed the 13.16.5.49 stock firmware to be succesfully installed? The installer not detecting a proper firmware anymore because of the damaged update due to ASUS Flash Tools hanging because my computer won't install ASUS Android Bootloader Interface?
Glad you got it going :good:

Need help unbricking my Axon 7

So I'm quite a noob when it comes to flashing/recoveries/bootloaders and things like that, and that's most likely the reason why I got myself into this situation. Anyways my axon 7 (which I bought in China a year ago) was running fine yesterday, just a little bit slow. I had installed TWRP on it, and flashed the US rom along with SuperSU root. However last night was when things all went wrong.
I tried to flash the xposed installer from twrp which caused me to not get stuck on the AXON boot screen when I tried to restart.
Seeing that my phone was now softbricked, I thought since my phone was already running so slow, maybe I should take this opportunity to install lineage os and at the same time unbrick my phone. Win win right?
But when I tried to flash lineage os, I got the red error 7 message and problems with mounting /system. I went into the zip and changed the updated script and tried reflashing the new lineage os zip. That didn't worked and I still got error 7 messages.
So I this point I was quite desperate to get my phone back so I tried to reinstall the stock axon 7 rom which didn't work as I ended up with unable to mount /system errors.
I tried to reinstall twrp but my pc wouldn't recognize my phone while it was in fastboot mode.
I tried this tutorial IGNORETHISTEXTCASUEICANTPOSTLINKSYETJUSTCOPYTHELINKTHATCOMESAFTERhttps://m.youtube.com/watch?v=T-7neHzSIvc but got stuck on the step where I needed to reformat my data partition as exfat (the progress bar just kept going). After waiting 3 hours for it to format, I thought it was frozen or something because the guy in the video was able to format it instantly.
So I force restarted my axon 7 and now I'm here:
1. Most of the time when I restart my phone, it gets stuck on the zte logo
2. occasionally it gives me the option menu (with power off, fastboot, recover, etc.)
3. If try to use fastboot, my pc won't recognize my phone
4. If I use recovery, I get stuck on the teamwin screen, but my computer seems to recognize my phones presence, in the fastboot command prompt the "adb devices" command displays my phone as "10109dd offline", if I run any other command such as reinstalling TWRP, the command gets stuck at "waiting for device"
5. Obviously can't boot into android cause my whole system partition is wiped
Anyways that's the state I'm currently in (all because I wanted to install xposed installer ) and I would appreciate any suggestions!
Make sure all your phone drivers and adb are up to date.
Also try the Zadig drivers these might help too.
In Windows device manager it should show as,
Qualcomm HS-USB QDLoader 9008"
If you get stuck you can always try using an Edl package.
I have and Edl help page here>
