[Q] Iconia A500 stuck on ACER logo, no more ideas - Acer Iconia A500

Hi,
I'm trying to repair a friend's Iconia A500 which is stuck on ACER logo.
My friend doesn't know the Android version of this tablet.
My tests have been done under Windows 7 64 and XP Pro, no antivirus, no firewall, UAC disabled on Win7 (always in run as admin mode).
All boot tricks have been tested (wipe / reset / hard reset... : power / vol - / vol+ / lock button...)
I tried to update with following files (renamed / extracted / decrypted if needed) on a FAT32 micro SD card :
Acer_A500_0.000.00_1.013.01_EMEA_GEN1_1300336887417_befd43a1

Android logo standing up with a rotating blue "ball" in front of him.
Android logo lying down with a red triangle (containing an excalamtion mark in it) above it.
I tried the APX mode on my PCs (with reset pushed down...), tablet is recognized as APX (USB eject displays : "Eject APX"), but "apx devices" and "fastboot devices" command doesn't display any device.
adb devices
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
List of devices attached
My tablet Vendor ID / product ID :VID_0955&PID_7820
I tried official Android drivers (adt-bundle-windows-x86_64-20131030) and others from another ZIP (root-3.2.1-V4) :
recognized as "Acer Picasso USB Boot-recovery driver".
I modified the .inf in each driver package to re-install the driver in each possible mode in order to obtain the following device name :
Android Bootloader Interface
Acer Composite ADB Interface
ADB Interface
Still unable to display my device via "adb devices"...
Any idea ?

Stuck installing TWRP w/ Kindle Fire Utility 0.9.1

Here's what I'm seeing...I've restarted the Kindle 4 times now and nothing is happening.
Any ideas?
Here's a link the pic : img18.imageshack.us/img18/6505/image1cb[dot]png
What are you seeing on your Kindle now? Are you in fastboot (Yellow Triangle with fire)?
I don't have FireFireFire installed. Basically I ran the Kindle Fire Utility and did a Permanent Root (after I unrooted using BurritoRoot)...and then ran latest install of TWRP....and everytime it gets to the actually instal part...I see that screen....
and when I restart my kindle (like it says to do in Kindle Fire Utility) it just restarts normally and then goes to USB connected screen.
Steps:
1. Download this .img for twrp.
2. Place it in the adb folder. (where ever you have to cd to)
3. Do the following commands:
adb shell
su
idme bootmode 4002
reboot
4. Download fastboot and place it in the adb folder and do:
fastboot -i 0x1949 boot twrp-blaze-2.0.0RC0.img
5. Enjoy your newly added recovery.
I'm now stuck in fastboot (yellow triangle with fire)
I tried to just press the power butter to load into recover but it didn't work.
I tried adb reboot, but it says no device is found...
Any ideas?
Edit: I saw a post that I need to re-install the drivers?
Which one:
Image: img809.imageshack.us/img809/7474/image3si[dot]png
did you do
idme bootmode 4000
to get it to boot normal?
adb commands arent working....do i need to reinstall the drivers? if so which one...it gives me three choices...
ADB interface
Bootloader Interface
Composite ADB Interface...
I'm assuming once I get adb commands working again...then I can use idme bootmode 4000 to get into regular boot mode again.
Edit: I tried chaning to Normal boot with Kinde Fire Utility...didn't work...
Really wondering if I should reinstall the drivers and try agian...but the KFU doesn't really seem to be playing nice with my device.
Not to say KFU is bad but I never used it. If you started with the directions that came with twrp we might not need so many topic about twrp help.
I just ran into the same problem!
ADB and fastboot commands don't work for me too, and I also tired to reinstall the drivers and still didn't work..
edit: try using KFU on another computer, and then changing to normal boot!
that seemed to work for me!
try to uninstall old/faulty drivers:
disconnect kf and use:
http://support.microsoft.com/kb/315539/en-us
connect KF and select the last installed driver (which you installed by running "install_drivers.bat") manually (check the date/time on selection)
Yeah, the KFU has just been a headache for me.. I finally got it working though, i have to use burrito root everytime I want to do anything after a reboot in KFU, but it works perfectly fine after that. Make sure you have good drivers installed under android phone also! Don't use the install_drivers.bat from KFU, just caused me more headaches...
i used the drivers from kfu - but after a cleanup - that seems to be the point
the difference is they are te only ones with entries for device 18D1 you'll nedd in fastboot mode or you can add the entries to your drivers under "kindle" or "kindle fire" or what it is called in your android_winusb.inf:
%SingleAdbInterface% = USB_Install, USB\VID_18D1&PID_0100
%CompositeAdbInterface% = USB_Install, USB\VID_18D1&PID_0100&MI_01
Well I was assuming they used a root method that already had them set up their own driver files etc. already.
no they don't - they try to provide drivers that are working in every bootmode - i've made corrections in the driver installer script for non english os which vashipooh implemented off ver. .9 - i have also device 18D1 in my adb_usb.ini - if it helps ? - but there's no downside
Maybe I'm just too tired (its 4:30 AM here) But I don't understand what you said... And the current version of KFU has a bad install_drivers.bat, it replaces the mass USB storage driver and it made my ADB stop working...
i think it don't replace the mass storage driver, it just reinstalls it - that's not they'r fault - it's the tool they are using from microsoft (devcon) to update existing drivers - devcon seems to be working this way - good or not ? - who know's ?
Wait, are you talking about the most current 9.1 or 9.0? Because 9.0 works fine, the new 9.1 kills USB storage, and for me ADB which kind of destroys the point.
9.0 - will download 9.1 and take a look - perhaps i can help to sort the problems out and contact vashi to correct the issue - thanks for the hint !!!
No problem, haha I knew there was something missing in that conversation, hope you guys can figure it out!

Here is how to manually install the drivers step by step.. If you think you may have a problem with the drivers that you have on your computer it would be smart to get download another .android folder and put it on the root of your c:drive just to be sure that nothing is wrong with it before you attempt this
- Go to start Menu and right click on computer, Click manage
- In computer Management hit device manager
- I am guessing that you see your kindle connected in there with a yellow ! by it
- Right click on kindle and update driver software
- Click Browse my computer for driver software
- Click let me pick from the list of device drivers on my comp
- Click Next
- Click Have Disk
- Click Browse
- Navigate to your user folder in that window/ or wherever your .android folder is
- Double click on .android folder
- Double click on Driver Folder
- Now Click open
- Now click ok
- Click Next
- ClickInstall driver software anyway
Hope that helps..!

[GUIDE] Alternate method for rooting the Kindle Fire system version 6.3.1 and 6.3.2

The main reasons to root the kindle is to gain access to the Google Android Market and or flash a Rom. The the act of rooting the stock software is very near obsolete in most cases. For one reason or another this appears to be an arduous task for the kindle, the computer, the utility and for the inexperienced user. There`s a better way, not a new way but far less talked about. My hope is to create a better safety net for the average user. A few simple steps and you`re well on the way. The process involves getting drivers installed correctly, putting a custom recovery in place as well as a bootloader, managing your first backup and installing a modified stock Rom with root. It`s a good idea to first understand some basic things about what your device will need to make all this possible. I do not believe it could be anymore clearly laid out for you than FSM Kinfauns wrote here [GUIDE] Kindle Fire For Beginners. If you`re new to rooting or just to the Kindle Fire this is a must see.
Drivers​
Well I`m sorry the first part is difficult at least for some users it requires getting drivers in order. I`m not going to go into great detail on this it`s very well highlighted in the second post of the above thread. Some things that may help installation.
Avoid using 3.0 USB ports users have had trouble with them not reacting well to fastboot causing serious problems.
Make sure your using the proper cable.
Run the Install_driver bat file first. Any errors during this may indicate the need for a manual installation. Windows XP requires manual installation.
Plug in the Kindle. Watch to see if windows shows installation of drivers and which one. Windows 7 usually shows a popup balloon of the driver it`s installing, click on it to view progress and type.
Open device manager. In device manager you should see "Android phone" click to view driver it should read "Android Composite ADB Interface".
If it reads "Android ADB Interface" more work is needed.
Right click then select update driver.
Click "browse my computer for driver software", and point it to the kindle drivers. On my Windows 7 machine, for instance, it's C:\Documents and Settings\HP_Administrator\Desktop\Kindle_Fire_Util ity_v0.9.6\Kindle Fire Utility\drivers\kindle.
Include subfolders and click next. Disregard any warnings update driver software anyway, preferably it will then read "Android Composite ADB Interface".
For manual installation here`s a very good tutorial. How to install Kindle Fire adb USB driver?
Driver flex test​There`s a way to test the driver before ever attempting to send anything to your device. The Kindle Fire driver is in and of itself multifaceted and Windows has only met with the first half of it. A mild introduction to the second half could very well prevent Windows from being confused when you need it function correctly for the technical part of this process. I would consider this "the lesser of two evils" with the only risk being stuck in fastboot. This far less under weighs actually physically breaking something if it were to fail.
Plug your kindle in.
Unlock the screen.
Tap disconnect at the bottom of the screen to stop the USB file transfer application if it auto launches.
Open device manager.
Launch Kindle Fire Utility.
Confirm driver indicates "Android Composite ADB Interface" in device manager and Kindle Fire Utility indicates ADB Status: Online / Boot Status: 4000.
In KFU select # 1 Bootmode Menu then select # 2 Fastboot <4002> the Kindle will be told to reboot in fastboot mode. Setting bootmodes with KFU takes a bit be patient.
Check device manager see that the driver reads "Android ADB Interface" without errors such as an exclamation point or a question mark.
Powering the device off and back on again while attached can prompt new hardware found for updating driver on XP and proper installation of the driver in Windows 7.
If it does have an error or Windows does not recognize the device you must once again right click then select update driver to make it read "Android ADB Interface".
Press any key to continue
If it says ADB status offline Boot Status: Unknown disregard and select # 1 Normal <4000> this will tell the Kindle to reboot in Normal mode.
After booted press any key to continue.
Press 0 to recheck device status.
Confirm driver indicates "Android Composite ADB Interface" in device manager and Kindle Fire Utility indicates ADB Status: Online / Boot Status: 4000. This completes the driver flex test. If you get stuck in fastboot don`t panic there`s no damage, just an altered bootmode. Keep working with your drivers, powering the device off and back on again while attached seems to work pretty well.
Device preparation​
Start with a fully charged battery.
This step is very important under settings/device turn on allow installation of applications from unknown sources.
Plug your kindle in.
Unlock the screen.
Tap disconnect at the bottom of the screen to stop the USB file transfer application if it auto launches.
Status verification​
Open device manager.
Launch Kindle Fire Utility.
Confirm driver indicates "Android Composite ADB Interface" in device manager and Kindle Fire Utility indicates ADB Status: Online / Boot Status: 4000.
TWRP installation​
Select # 3 Install Latest TWRP Recovery. The Kindle will be told to reboot in fastboot mode. If all goes smooth it will reboot, in the terminal it will download the recovery, send it, write it. Then return your kindle to normal bootmode.
If nothing happens after 3 or 4 minutes and it just sits there <waiting for device> simply hold down the power button while connected till it turns off then turn it back on again. This could even take a few times always wait the 3 or 4 minutes in between.
Bootloader installation​
Hopefully now the risky part is over and you`re booted back to the stock OS of the kindle.
Swipe to unlock the screen.
Do not disconnect the USB file transfer application. If it fails to auto launch touch upper left of screen, tap USB is connected select to copy files to/from your computer. This will show the contents of your sdcard on your computer.
Download bootloader only from here [bootloader][05-26] FFF 1.4A bugfixes + new look + recovery boot [.zip file size]. All files to be flashed in recovery must be in zip form. DO NOT EXTRACT. Do not use the bin file from KFU it`s not intended for flashing in recovery and will break the bootloader.
Drag and drop fff-u-boot_ v1.4a.zip on to your sdcard but do not place it inside of a folder.
Then disconnect the file transfer application when finished transferring.
In KFU select # 1 Bootmode Menu then select # 3 recovery <5001> this will tell your kindle to enter recovery.
In TWRP select install then locate fff-u-boot_ v1.4a.zip tap on it and flash it, leave the boxes unchecked.
When finished hit the home button upper right to return to TWRP home screen.
Select reboot.
Select system if prompted.
First backup and flashing rooted stock​
After reboot Swipe to unlock screen.
Do not disconnect the file transfer application.If it fails to auto launch touch upper left of screen, tap USB is connected select to copy files to/from your computer.
Drag and drop this Rom zip onto your sdcard [ROM] 14 Jun Gr9 (6.3.1) - MoDaCo Custom ROM for the Kindle Fire. Use the standard version not the altrom but do not put it inside of any folder. I`m not trying to highlight just one developers work but this is needed for this method.
Disconnect the file transfer application after the transfer has finished.
Unplug kindle from pc.
Power the kindle off , then back on again. When you see the white Kindle blue Fire logo quickly depress the power button a few times till you get a boot menu select --Recovery--.
In recovery select backup the default selections are fine, swipe to backup. This backup you will later rename noroot631 without spaces. Adding spaces will cause it to fail if you need to restore it.
When finished hit the home button upper right.
Select install.
Tap on GR9 Modaco zip and flash it. Do not enable force MD5 check or zip file verification or it will fail.
When done select reboot.
Select system if prompted.
Final result​
When the Kindle reboots it will have root and have the Google Android Market in your applications.Take note that this is the only Rom that you flash without doing the proper wipes. To increase your safety net it is recommended to perform an MD5 check on fff-u-boot_ v1.4a.zip and Gr9 (6.3.1) - MoDaCo Custom ROM for the Kindle Fire using this application WinMD5Free. You may ask" Why so many steps?" or "Why not flash everything at once?" This is to insure everything works throughout the process and prevent mishaps. The entire point of this thread to avoid having to use a factory cable or firekit to rescue your device because something went wrong. I hope that some of my tips and tricks will make your rooting experience safer and easier. Good luck and have fun.
How to flash another Rom​
1. Transfer Rom zip and matching gapps zip to sdcard.
2. Enter recovery.
3. Create a backup.
4. Wipe factory reset.
5. Wipe cache.
6. Wipe dalvik.
7. Wipe system.( unless same Rom, same system, same developer)
8. Flash Rom zip.
9. Flash gapps zip.
10. Select reboot, then system if prompted.
11. Enjoy!
A very special thanks for all they continue to teach me and coaxing me to strive for more.

adb_usb.ini needs to be located in your .android folder if its not copy paste it from Kindle_Fire_Utility_v0.9.6\Kindle Fire Utility\drivers\kindle to .android and plug your device in. Make sure that 0x1949 is written in if its written in twice or not written in the device will appear offline.

abd Server offline and offline and offline......
Hello
I have a very neus Kindle Fire. Unfortunately I can not make it to rooten it.
For two days I build drivers back and forth. Always unsuccessful. The adb server is offline. Can it be that the device is too new? The device connects normal with win7. All attempts failed to use the modified drivers. It was only when I entered in my driver hardware ID from the Kindle (USB \ VID_1949 & PID_000A & REV_0216
USB \ VID_1949 & PID_000A) I was able to install the driver. Then stood in Device Manager under Android Phone ADB interface. Unfortunately the Kindle but then disappears completely from the workplace. But brings no good, the adb server is offline. Weis someone whether to run the adb server must also, not even when the kindle is connected? In Task Manager starts at least the adb exe.. Comes in the shell, but the message is written if I have adb properly etc.
I hope anyone have any advice.
Greetings and thanks

I had the same issue, I had to rename the recovery file name to twrp.img then it worked perfectly. Also delete the file you created for twrp in the recovery directory in the kfu package and just replace the copy of twrp (if the is one there) in the recovery folder with the one you downloaded and renamed.
Sent from my SAMSUNG-SGH-I317 using xda app-developers app
everything is set but when i open the KFU 0.9.9 it look like this.
failed to copy 'files\fbmode' to '/data/local/fbmode': Permission denied
This is a great guide that goes into more detail than most of them which helps a lot for troubleshooting.
Unfortunately, the /data file system on my fire is read only, so copying the files to root it is not possible. I'm using KFU 0.9.9 and the kindle is running 6.3.2. Compter is windows 7 64-bit. What do I need to do to get permission to write to the kindle's filesystem? See the screenshots below.

[Q] ADB error new Defy XT557D

I received new Defy XT Dec. 17 from Republic Wireless and wanted to move as many apps as possible to SD card without rooting as discussed elsewhere.
However, after enabling USB debugging on the phone (Settings - Applications - Development) and connecting the phone to the computer with the USB cable here is the message when I type command "adb devices".
adb devices
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
List of devices attached
???????????? no permissions
command "adb version" returns:
Android Debug Bridge version 1.0.31
Apparently my Defy is not recognized and of course no other adb commands work. I'm not using Windows. I'm using Linux, Ubuntu 12.10. I've used adb successfully on same computer with Acer Iconia A100 Tab. Attached file contains pertinent messages in syslog when usb cable from Defy is connected to computer. Any help with why this device not recognized by adb would be appreciated.

Correct Partition Set Up

Hi all...
I have a Nexus 6P that just sticks in a Google bootloop.
The phone has USB debugging on and the bootloader unlocked.
I have the correct Google USB driver installed and in windows 10, Device Manager it shows up as 'Android Bootloader Device"
-- properties of this tab shows device working ok
When i connect the USB data lead (i have tried now several) to the PC and phone... the PC makes a tone to confirm connection.
I have downloaded the latest Fastboot and ADB driver package (platform-tools_r28.0.1-windows).
When i command prompt into the folder that houses Fastboot / Adb , i am able to do the following:-
ADB Version --> Android Debug Version 1.0.40 Version 4986621
ADB DEVICES --> List of devices attached (blank)
---> i tried ADB KILL-SERVER --> * daemon not running; starting now at tcp:5037 *daemon started successfully
I then retry the command ADB DEVICES and again i am shown --> List of devices attached (blank)
When i use the following Fastboot commands, i fair better:
FASTBOOT DEVICES --> "Serial number xxxxxxxxxxxxx" fastboot
FASTBOOT FLASH RECOVERY TWRP.IMG --> Sending 'recovery' 16425kb Failed (write to device failed in Sendbuffer () Unknown error Finished Total time: 5.006s
I am confused as i know i have connection from PC to device?
I have tried in Win10, Win 7 and Linux...all the same as above?
I believe that my partition tables are screwed?
Is there a command I can execute that will reset the phone partition to make the partition writeable...thus it will take a custom recovery?
Many thanks for everyones help
