New A700 can`t recognize PC (No TA-DA sound) - Acer Iconia A700 and A510

I have a brand new Acer Iconia A700 and USB port works well for all external HDD or flash pen drive via OTG cable, but PC can`t recognize, no TA-DA sound. Maybe output port is broken? Tested with 3 different micro USB cable, 2 notebook (XP an 7) and 1 PC (XP). In setting options i have selected "Media device (MTP)". I have an stock rom Acer.AV051.A700.RV16RC01.EMEA_DE.
Any solutions? :crying:
Thank you in advance!

If you check the Windows Device Manager, is an unknown device present? If so, try installing the Acer USB drivers. You can download them from the Acer website
"www.support.acer.com" and choose your language. Select tablet, select Iconia A, Select A700, Choose tab for USB.

Thanks for answer, but my Win is ready for my tablet, i have installed USB driver, and Acer Sync but in vain, nothing. Perhaps USB output is death or JB 4.1.1. I don`t know! Tablet is it in warranty but i bought in another country.
Later Edit:
Yesss... usb is working now. I simple boot into recovery mod and reboot and surprise usb works!
This key combinations :
- Press [vol-] + [power]
- Once the tablet vibrated, let go [power] and keep [vol-].
- Now the tablet vibrates a second time, let go [vol-] and press [vol+] quick
- Once the text that appears on the screen ("loading recovery kernel image"), let go [vol+].

i assume that you have usb cable plugged into the pc
for english wm6 search hp SP38077
it must match your SKU ID (P/N) otherwise it says you have wrong version.
my skuid is:FA908AA#ABB -> SP38077
i have windows vista installed and it works
1) take out the battery
2) remove USB cable if connected
3) insert battery
4) push and hold the silver center of the 4way key and press red phone key (switch on)
or see http://h20000.www2.hp.com/bizsuppor...=3375716&prodTypeId=215348&objectID=c01087938
this will make hard reset
5) computer now recognizes HP USB Sync
if not, then remove the battery and remove the cable.
then insert battery again
then hold volume down (bottom part of the silver key on left side of phone)
and insert USB
now it will enter bootloader mode and if previosly not installed then now installs hp usb sync
now start HP Rom update utility with your preffered language (en or fr i dont know)
and it will connect to the phone and upgrade a firmware and voila phone is ALIVE !

[Q] How to format install and root BSNL Penta Tpad IS701c

Hi,
I own a Bsnl Penta Tpad IS701c Tablet which has the following specification:
1. 1 Ghz Cortex A8 Processor
2. 512 MB RAM
3. 4GB Rom
4. Expandable to 32GB via Micro SD Card
5. HDMI Port
6. One Mini USB and One Full USB 2.0 with Mic Facility
7. VGA Camera
I was trying to root this tablet since it was performing very poorly but wasn't able to do so, so I tried to downgrade it from ICS 4.0.3 to Gingerbread. Flash was successfull but now the tablet is stuck on the Andriod Welcome Screen and I am unable to use the touch screen. Also when I am trying to shutdown it doesnt allow me to do so and Hard Reset is also not working.
Need your assistance in resolving this problem.
Resolved: How to format install and root BSNL Penta Tpad IS701c
Hi Guys,
I previously was looking out for an answer regarding how to upgrade firmware and unlock root access for BSNL Penta Tpad IS701C tablet. After 3 sleepless nights I have been successfully able to do the same and here is how you can restore your broken tablet (if its the case).
Prerequisites:
1. BSNL Penta Tpad IS701c Tablet (at least 50% charged or put on charging and continue)
2. OTG cable
3. Windows XP Operating System (I used the same since I was unable to load the ADB drivers using Win7)
4. Downloaded driver pack from pantel website for your device (For my device, New IS701C 20121201)
Procedure:
1. First of all, Download the Driver Zip pack and unzip it anywhere on your desktop or laptop
2. Next open the unzipped driver pack and run MPTool.exe file.
3. Next step is the connect your OTG cable to your tablet and then your PC/Laptop (Make sure that your tablet is in OFF Condition)
4. Now, insert a pin in the reset hole of tablet and press the Power Button for 5 secs (your tablet will start in Debug Mode and you will find Andriod device pop up on your PC/Laptop by the drive name as Vrdu or something).
5. As soon as the device is connected respective Port name in above picture is highlighted in Green with status as 'Ready' ( Buckle up as your are all set to flash your device)
6. Next up, click on 'Erase' to flash your ROM (this is advised to avoid any boot failures due to some junk data in Rom if you choose to just Download the ROM without Erasing it first, as good as Format your Hard disk and then clean install your OS simple!!)
7. Once done, you will get a pop up message 'Download End' and in background you will see 'Erase Success'.
8. Click on 'Download End' button and then click on 'Download NAND' button. ( Download will start, please be patient while this happening since it will take some time to complete. DO NOT TOUCH YOUR TABLET TILL THEN.
9. Once the download process is completed, you will again see 'Download End' pop up and in background you can see 'Download Success'
10. Next up, to patch your device ID, enter your device number as received with warranty card and click on 'Save and Return' button.
11. Now click on Write Chip ID ( you will get success message as before)
Viola!!!! you have just completed flashing your ROM and installed Andriod ICS 4.0.3 with some prepackaged softs.
Test:
1. Unmount your Andriod Device from PC/Laptop
2. Remove OTG Cable
3. Press the Reset button once ( Device will be shutdown)
4. Press Power button for 5 secs and.........
CONGRATULATIONS....your device is up and running brand new Andriod ICS OS.
Note: The device is powered by VIMICRO VA7882F chipset just an FYI.
Happy Andrioding!!!!

Hi,
The above method is for Penta Tpad IS701c. If you are trying to install this firmware of IS701r it will not work since there is a difference in the touchscreen hardware. Please download firmware from Pantel website for IS701r and try it once.
Always happy to help!!

Hi,
What OS are you using on your desktop or laptop? I used Windows XP to update flash my firmware coz its comparitively easy. if Win 7, there are problems as Penta tablet is not recognized by default so you need to specify Generic Andriod ADB drivers. Once the Andriod device is recognized Vdfu named drive is opened. and then you can run the VIMICRO tool in the firmware setup you downloaded. Then first erase the rom and install the new ROM. Its fairly easy process if you still have any issues let me know. Old firmware was without HDMI support while new is with HDMI support I flashed with new IS701c firmware.

Hi All,
Sorry for hacking this post. I bought one BSNL Penta 701c Model, and when I open camera it says "Internal card is empty"" . When I insert the SD card it is not mounted. And the tablet details are
Model Number : 701c
Android Ver: 4.0.3
kernal Ver : 3.0.8
Build Number : PENTA IS701C 20121012
I was trying to flash my device. But even after enabled USB debugging the device is running in to debug mode.
I tried this unlock tool mentioned in thread(http://forum.xda-developers.com/showthread.php?t=1969766) and it says device not found.
Any help ?

There are two versions of Penta IS701C hardware. Build nos 20120717 & 201209xx are considered old and there is a new version 201212xx.
This is amazingly lame on the part of Pantel Tech. They should have changed the model no to atleast IS710d or IS701E. Now when the
above 2 "old" versions hardware is flashed by "new" (angry birds space) rom/driver version, it causes trouble. TouchScreen problems
are the first headache as the tablet becomes unusable. (Try connecting a mouse on USB port. On my functioning tablet it works nicely).
Similar problems happen if "new" version hardware is flashed by "old" driver/rom version. I had recently emailed Penta tech support and they
cautioned me against updating my tablet with "new" angry birds space rom version.
One solution would be to download the "old" version of drivers from the Penta website and flash them.

Where do you find this MPTool.exe. If it comes along with driver download from Penta website, could you please zip it and
post it here in this forum. The driver package is huge and I don't want to download it just for one tool.
Actually I want to try to take the backup of the IS701C rom using MPTool. There are many versions of MPTool floating around
on the web for different kinds of devices like pendrives, phones, tablet etc. Right one should be used.
Taking a complete backup image of this tablet is proving to be challenge. It appears there is no recovery firmware compatible with it.
So softwares like ROM manager, ROM Toolbox, Titanium Backup, Online Nandroid all fail to make a complete image of the ROM.
While apps and there data can be backup by Helium backup, the system partitions remain out of reach. It is always good have a
complete backup in case something goes wrong in the future.
Best Regards,
VK Singh
useful information indeed @MadMax, it worked for me, thanks
After RESET use button POWER+VOLUME- (volume minus) to get into debug mode.
All the above steps are working. just after using RESET button use HOME BUTTON+VOLUME DECREASE BUTTON to get into DEBUG MODE.
otherwise the tablet do not go into debug mode.
try it. its working well for me.
thank you for the post by MADMAX87.:highfive::good:

Hi,
My BSNL PENTA IS701C was having issues in accessing the Internal & External SD card memory. Hence I have reflashed the tab with the firware from the Patel.in site (IS701C OLD 20120918) with the help of PC & external SD card. Now after flashing the firmware, the Touch Screen is not working (but the SD memory card is working fine). Mouse connection is working fine. I believe the firware version is wrong.
I tried reflashing the version NEW IS701C 20121201, but I couldn't so because the MP tool is not recognizng the device. I have inserted the pin in the reset hole and pressed the Rest and Power button simulatenously for 5 sec. The tab boots normally and the in MP tool the not device is selected and Erase/Download NAND buttons are not enabled. But I am able to access the SD cards from the PC. USB Debug is enabled. Kindly help me in fixing the issue.
Thanks in advance.
To Mr. Pallav.
29-Oct-13. Dear Mr.Pallav, Your info "Build nos 20120717 & 201209xx are considered old and there is a new version 201212xx." acted upon us as MOST VITAL info. So, we downloaded the new OS accordingly from Website - mytabletguru [dot] com. Immense thanks and gratitude.

Soft bricked Panasonic P81

Hi Friends,
This is my first post at XDA.
I unfortunately bricked my Panasonic P81 after rooting it and adding XHalo app and the boot manager app from the Xposed Framework.
The situation is as follows-
I can get to the logo, it screams Panasonic and then doesnt boot. I dont have CWA installed and worse, my SD card which had my stock backup is also lost. This means I need a mechanism to stock recover and perhaps flash boot.img and recovery.img?
I am stuck at this point, not sure how to proceed. I can get to recovery, have cleaned cache, backed up user data ,done a factory reset. Even after factory reset it still cant boot.
Please help me with a step-by-step instruction to recover, this phone is dear to me. How do I flash?(boot.img or rom) I have downloaded Sagar Patel's (good bless him!) backup and the images, but need guidance on how to flash and recover.
Please help friends and apologies for any incovenience. I am still a newbie
Guys please help!!

Hope drivers are installed properly in your pc.
If you are going to use sp flash tool, Make sure SP flash tool is set to auto-detect com port, not manual selection
If you find that it is driver problem, following may help you.
Please note that there is nothing that much hard in driver installation as it is just to connect your device with your pc but because many users still face problem of driver installation, you can try following tricks!!!
It is observed by me that driver installation and adb interface problem do not happen in windows XP as eventually and generally it is happened in windows 7 and later…so, you can simply try on windows xp if you are able to do so…(you can use dual operating system too!!! Or good relation with neighbor/friends/colleagues/someone/all can be beneficial here!!!)
Note that all tricks here are not necessary to work, but it may still work for you….
Take one by one step, if the first step does not work for you, only then try next step. This is not all steps to be taken at once type guide…This is simply Try and error type tutorial/tricks…
There are following problems I have come to know regarding to driver installation and conflicts:-
Device is charging through usb cable but there is no usb option displaying on either device or no driver installation box/message/pop up appears in pc….
Missing sound of that usb-pc connection
Sound of disconnection after couple of seconds of connection
Adb interface is missing
Ok, sometimes changing usb connection type for example, from mass storage or mtp to camera, ptp, usb tethering or something else can bring adb interface…..
Try with different USB Cable. You can use original nokia or samsung tiny cable instead of cable having long length. Sometimes, length matters!!!!
Try in different USB Port.
Sometimes, you have to disable signature verification in your pc for proper installation of driver.
Had you disabled your antivirus before downloading, installing and while running your tools/softwares? You may need to do so…
Have you installed the software (or say, all associated softwares/tools) in C-System drive?, if not, then you should first install required software/tools in system drive that is usually C drive in Microsoft-Windows OS…or try after installing them on desktop.
Keep all necessary files/tools (driver files, flash tools, rom etc…) on desktop.
Download proper driver According to your model/device, According to chipset inside, According to Official site of manufacturer, Official site of chipset, through PC Suite/flash program of your device…
If the problem still not solve, you should try all available driver packages of your device one by one whether from official site of chipset inside your device, or any forum, adb, pdanet+ or foxfi, universal driver, VCOM Port driver, drivers from hexamob through play store, and find all possible packages and see if someone make positive result after installation…
If the problem still not solve, you should install remaining update packages of your system (PC) including all primary, secondary, essential, Non-essential updates….whatever, just install them all….reboot your pc…and see if problem is solved….
If you can connect the device but somehow found that device driver still not installed properly, just go to device manager in your pc, click on portable device, right click on your device and apply “Update driver”. Click on “automatically search” when a window prompt ask you.
If the problem still persists then,
Just remove all the drivers using usbdeview (I have given link also to download usbdeview in earlier post)
https://drive.google.com/folderview?id=0B511A2txfpAPbmwtQXZqbnVlT1U&usp=sharing
Install usbdeview and remove all the drivers
You can also fix this by showing the nonpresent devices in devicemanagement (google for show nonpresent devices for explanation)
Go to com ports, and delete all mediatek drivers except preloader driver. Now start over. It can help if you choose the same usb port where you had success last time.
Use Usbdeview to uninstall all the drivers before connection, restart the pc, Extract and keep driver zip files and other useful files/tools on desktop…just start your tool… and try to perform your tasks like backup…or restoring the backup…without worrying about that sound of disconnection you may listened after couple of seconds of connection or don’t even worry if you are just missing that sound of usb-pc connection….just try on your tool…
If still problem of driver installation persists, then simply use usbdeview and uninstall all drivers, restart your pc and try following steps:-
There are various ways to install proper drivers at the time of connecting the device with pc depending upon how you connect it.
Follow the procedure both with and without battery
Simply plug in via USB Cable
Connect by holding volume down button
Connect by holding volume up button
Connect by holding Power button
Connect by holding power and volume down
Connect by holding power and volume up
Connect by holding both volume up and down button
Connect by holding thrice volume up, down and power button
Connect by holding power and home button
Connect by holding power and menu button
Remember which method works and which drivers are installed
in LAN-Devices you may have different android device
Select/set drivers by hand and use the mtk usb driver, now Flashtool finds the phone
Suppose holding volume down method without battery works for you then what next you have to do is as below:-
1.TAKE THE BATTERY ,SD ,SIM OUT OF THE PHONE
2.HOLDING VOLUME DOWN CONNECT IT TO PC VIA USB(ONCE YOU HEAR A SOUND FROM PC YOU CAN RELEASE VOLUME DOWN)
3.OPEN DEVICE MANAGER(ON COMPUTER SEARCH IT OR CONTROL PANEL)
4.WAIT FOR 2-3 MINUTES
5.YOU WILL HEAR A SOUND & OTHER DEVICE WILL BE DISPLAYED
6.IN OTHER DEVICES ->MT65XX PRE-LOADER
7.RIGHT CLICK MT65XX PRELOADER
8.UPDATE DRIVER
9.LOCATE THE DRIVERS PROVIDED ACCORDING TO YOUR OS(VISTA,WIN7,XP)
10.IT WILL DO ITS STUFF
Install Mediatek drivers, preloaders, VCOM port etc…
Manually Install MediaTek USB VCOM Drivers
Requirement:-
1. Download MediaTek USB VCOM Drivers
2. Download USBDeview

8. Click Open and OK. You will see the drivers listed.
9. Select your driver there (select Mediatek Preloader USB VCOM Port)
10. Click Next and finish installing
11. If SP flash tool or other software still dont detect your phone then also install Mediatek DA VCOM (consider installing more from the list of drivers one at a time if need be)
Try in different PC
Sometimes windows XP works when windows 7 fails!!!
Case:-
It did the same thing with my MT6577 (Wiko Cink PEAX), so I connected it with a battery and without holding VOL+. Then "MT65xx preloader" appeared in device manager then disappeared (once). It is normal that it disappears. When you start Flash_tool and when you click Download (or whatever you want to do) THEN you connect the phone (in off state), and the flash operation will succeed.
Guess what? Once my Panasonic P81 could install driver and got detected after approx. 5 hours of continuous connection with win 7 x64!!! Meanwhile, I tried first usbdeview and then manually installation of mediatek driver but manual installation had failed as my p81 was only charging when it was connected with pc….So, mediatek – windows 7 conflicts….but, when I tried tiny (very small) nokia usb cable, it works instantly…
If you ever meet problem when you connect your android with your pc via usb cable and find that your android is charging but could not recognize or there isn’t that options of “USB connection” then just disconnect your android, power off it, remove battery, connect it without battery with your pc through usb, let it have some time to recognize your android or hear that voice of “usb connection” you were just missing…after that, insert battery and switch on your android…you are done!!!
Sometimes removing both sim cards and battery and then re-inserting them after a couple of seconds also works.
Try with different USB Cable
Try in different USB Port
Try in different PC
Sometimes windows XP works when windows 7 fails!!!
Use usbdeview to remove all the usb devices and then add your device
Find proper driver of your device:-

In my opinion MIUI is best because it has a self large community like xda and launch updates per month so many that you will fed up installing them.....if you download and install one update you will be amazed that it will say 3 more system updates pending......and if you complain a bug next month it got fixed.....only thing is to find one...
PS don't download the miui 6 for p81..complained by many p81 user that it hard bricked the device.
And that miui is not official i.e. some developer made his own one and DO not tested that it works or not......

[Dump] Captiva 10 Inch Tablet

Captiva 10 Inch Tablet
Modell CAPTIVA PAD 10
Android: 4.1.1
Kernel Version: 3.0.8+ [email protected] #29
Build-Number: RK30_ANDROID4.1.1-SDK-v1.00.00
ruifu_V2.60.20121105.dc72a7b
Well i did a dump from the Captiva 10 Inch Tablet. We had two, one died so we did a dump from the working one and put it back to the dead one and it is working again.
So now I want to share with you, how it worked for me, and of course the working system dump.
So if one Captiva Tablet isn’t working anymore turn it off.
After that do the following steps:
1. Load the 7-Zip file and extract it.
2. After that turn off the Captiva tablet.
3. Insert a Micro USB cable in your computer.
4. Hold Vol+ and put in the Micro USB cable in the USB Port on tablet side (not the “Host” port).
Now Windows should try to find a driver for the new unknown device.
5. So open up the device manager of your Windows system.
6. Right klick on the Unknown Device and update the driver manually.
You will find the driver in the Android Tool Folder which is included in the downloaded File.
Depending on your local Windows take the x86 or x64 driver.
7. After you installed the driver manually, you should see the device as a new class usb device, in this case “rockusb device” or like “rk30sdk”.
8. Next step is to open the “AndroidTool.exe”.
9. The bottom should display “Found One LOADER Device”.
10. You need to deactivate the “Loader”, “Resoruce” and “Parameter” in the Tool.
11. Next you change the path of “Kernel”, “Boot”, “Misc”, “Recovery” and “System”.
12. Just doubleclick on the Path to change it manually or click on the right field of the changing part and a pop-up windows displays your windows explorer, so you get manually the way through the explorer to the extracted file from our downloaded file.
13. I deleted the not necessary parts in my example. Even don’t wonder of the “No devices found”, because I did connect the captiva tablet to my computer for the tutorial.
14. After you changed everything like on my screenshot (Folderpaths can be different), click on “RUN”.
15. The tool will copy every IMG to the tablet.
16. After it finished your tablet should start again.
17. Please disconnect it from the USB cable.
18. Turn the Tablet off.
19. Hold the Vol+ and put in the Power Adapter.
20. Still Hold Vol+ and Push the Power Button.
21. The Tablet should start into Recovery. If there is an android with a red Triangle – You are in the recovery mode. If not, try again.
22. To go on push Power Button and Vol+ one time together.
23. The menu of the recovery should appear and just go to “Wipe Factory Reset” with the Vol+ and Vol- Button.
24. Press the Power button for Enter the Factory Reset.
25. Accept the Reset.
26. After that Reboot System.
27. Congrats. The Tablet should start normally.

Hi,
hopefully, you have not already deleted your dump. I happen to have a Captiva Pad 10 which only boots into recovery mode (android with red triangle) and then reboots only to display that android with the red triangle again (boot loop).
Perhaps I can fix this device using your dump. Your help would be greatly appreciated.
Thank you very much in advance and kind regards,
