Sorry for my English I will try to explain my problem.
After rooting everything was fine, but when I try to flash stock firmware somethings happen.First problem is that my PC cannot detect the phone with Odin and adb or mass storage I am 100% sure that the problem are not the drivers because I root that phone on the same PC before a week and of course I try everything on a another computer, but without success.
Download mode Odin cannot detect the phone! after many attempts to fix usb problem now the phone cannot boot , only in recovery (loop)after every start it's show recovery with message
Filesystems:
system: rfs
data: rfs
cashe: rfs
maybe system, data and cache files are erased I don't know.
recovery version is 0.1.3.b5
How can I flash stock firmware without PC. For example HTC devices can flash from SD card - Gold card, and PB99IMG.zip (I can't explain very well what I mean sorry)
Maybe the phone is usb bricked !
working..
recovery - only recovery
Download mode Volume Down + power off + camera ) - but cannot connect to PC and Odin.
not working
after flashing new costume ROM - the same thing - reboot to recovery
installed software on pc
android SDK,Kiesmini_1.0.0.10075_1,Samsung PC studio 1.5.1.10064_2,Drivers for spica on (Windows 7 x86)
really I cant find post like this !!! and sorry for my English
If you can go to download mode and phone is not detected, then you have bad drivers or bad usb in PC. Try another PC.
I have 3 pc and 2 cables and the same problem cannot detect. Can I flash new stock firmware without odin ?

Have you tried different USB ports, specifically one on the back of the PC?

I told you that the problem is not drivers.Before week I flash another Samsung without problems. I think the problem is USB brick or something else
I HAVE DRIVERS

Calm down. Did you read what I posted above? I said nothing about drivers. Have you tried other USB ports? Most people find the ports on the back of the CPU work the best, not ones on the front, or on a hub. It does make a difference.
Am I stuck in APX mode with no USB connectivity and how do I get out of this? Here is what happened:
A500 with OTA Android Build: Acer_AV041_A500_1.033.00_PA_CUS1
Windows 7x64 with UAC turned off and restarted OS
- Launch Afterota v1.09
- Info tab > Install Driver ... "ACER ICONIA 3G DRIVER INSTALL"
- Boot A500 > ENABLE USB debugging
- Plug USB cable into A500 ... "Acer Iconia Tab A500 ... Your device is ready to use"
- Tablet Information ...
Tablet Serial : 11933073415
Tablet Cpuid : 028841854280E4D7
Tablet Sbk : 0x15290000 0x7FC6C006 0x47E52404 0x302C2103
Android Build : Acer_AV041_A500_1.033.00_PA_CUS1
Bootloader : 0.03.12-ICS
- Save Values to AcerIDs.txt
- Standard tab > Bootloader Ics v3.14.8 + Recovery Thor v1.7.3 > For A50X
- Install sys rw patched kernel (sys rw patch only, no overclocking)?
- Yes > OK
- A500 boots to APX Mode
- Afterota status ... flashing (about 1 minute) ... idle (no further activity ... ever)
A500 screen is BLACK, Power LED is ON, all the Afterota buttons are grayed out except for Unsoftbrick Browse.
Driver: OK - driver installed
Usb: ERROR - connect usb cable and enable usb debugging
I've tried reinstalling the USB driver multiple times and using different USB ports with no luck. I can turn A500 on and off by holding down the Power LED button for 3 seconds, but still a black screen.
Any ideas will be appreciated
May have a possible Fix for you
EDIT: OK May have a possible Fix for you I've just run this myself from apxmode and it worked for me...give it a whirl and see how you go!!!
check this thread here
##############################################################
the 'mode' yr tab is in now - black screen with power lite....
i'm sure its waiting for the apx driver to load this will enable yr tab to enter the next stage where the flash takes place..(this stage is called different things depending on which tool u use...which doesn't help matters at all...) you will know when u enter "the next stage" because yr tab will display some white text "a500 apx mode" or "acer download mode" even "a500 bootloader mode" they're all the same -
so if u do not have the white text displayed the only conclusion one can come to is that the required driver cannot be found....(if I'm wrong on this then please put your 2cents worth in and maybe we can get this problem solved once and for all)
you need to have the "acer usb-boot recovery driver" displayed in your system tray under safely remove h/w or in device manager. Is it there....?
Device manager is yr friend always have it open when trying to troubleshoot flash issues.
connect yr tab to yr pc with yr mini usb data cable - the flash will definietly not happen if you're using a regular sized usb cab le!!!!
is the driver listed under usb controllers?
is there an "APX Device" listed?
if not disconnect and power yr tab off
then enter apx mode manually and reconnect cable and see if the boot-recovery driver installs itself - if it doesn't then reinstall the acer drivers....again!
also if it hangs on the black screen again
always disconnect yr usb cable close the program down and try again.
your other choice is to use civs nvFlash cos it requires yr tab to be in apx mode first - if it fails it will show you an error which will help
There seems to be alot of ppl of late getting stuck in this mode...and there seems to be no real solution to it.....sometimes you just have to keep at it until it works... if all else fails then u may need to downgrade back to HC and try from there!!!
Please let us know how u get on....
cheers
EDIT you need the android drivers too - theres a zip file in my cpuid thread if u need them
I've tried your suggestions, only using AfterOTA so far ... still no success.
These are the steps I've been following:
1) Disable UAC > Restart
2) Run Afterota.exe
3) AfterOTA (Info tab): Install Driver
4) Power on A500 (screen is still black, Power LED is white) ... plug in micro-USB cable from PC ... "driver successfully installed"
5) AfterOTA (Advanced tab): Unsoftbrick ... browse to ... recovery_thor17_403.img
6) AfterOTA (Advanced tab): Unsoftbrick ... browse to ... ics_boot_unlk_V6_500.bin
7) AfterOTA (Advanced tab): Unsoftbrick ... Install
[1/3]loading apx mode bootloader
[2/3]flashing recovery ..
This is where it gets stuck. No vibrating, the screen remains black (no text), nothing even after 5 minutes. I've repeated steps 5-7 trying two different USB cables plugged into the A500 micro-USB (small) port and also connected to different USB ports on my PC. Each time I shut down AfterOTA, unplugged the USB cable, powered off A500 ... then try again. I've also tried uninstalling and reinstalling the USB driver using AfterOTA.
Every time A500 is powered on and connected to USB ...
- "Acer USB Boot-recovery driver" is listed in Device Manager, USB controllers
- "APX" is listed as an Unspecified device in Devices and Printers (not in Device Manager)
- "Usb: ERROR - connect usb cable and enable usb debugging" listed in AfterOTA (Info tab)
It appears AfterOTA can't establish communication over the USB connection.
The very first time I used AfterOTA, A500 was still able to boot to ICS, the USB connection was OK and I was able to retrieve the Acer IDs and save them to a txt file. It was only after flashing "Bootloader Ics v3.14.8 + Recovery Thor v1.7.3" that I got the "Black" screen. It appeared the flashing was successful, as it had completed step [5/5] and then showed status "idle .."
I guess first priority is to find a something (maybe other than AfterOTA) to see if it can communicate with A500. Haven't tried civs nvFlash ... yet.
Thanks for your help.

ok, this is weird:
you are saying device manager reports the boot-recovery driver installed
But there is also an unspecified APX device????
Are u using win7/64 by any chance as there have been some issues reported by those users - are u able to try another pc??
Try manually installing the driver the apx device, by pointing it to the acer folder in program data
what happens there??
- "Usb: ERROR - connect usb cable and enable usb debugging" listed in AfterOTA (Info tab)

- while yr tab is in apx mode you will have no access to adb or usb b/c apx is using the USB connection -

Yeh I wish it were that easy - I've been working on this for a whole week now, as lately there have been a number of "stuck in apx mode" reports - altho yours is the first of it happening using afterOTA - there just doesnt seem to be an easy way out of it,,,its happened twice previously on my tab - i got it working but i cant tell you how....i just kept trying over and over till it worked!!!
If you do give nvFlash a try - edit the .bat file and delete the "cls" commands this will give you a chance to 'see' whats going on...
another tip: after entering your sbk make sure the "system information" window pops up - it will show amongst other things your "chip uid" this is yr cpuid - if you carry on without yr tab being in "bootloader mode" you can end up with a really, truly 'brick' on yr hands - see the walkthru in my sig if you need further guidance
[1/3]loading apx mode bootloader
[2/3]flashing recovery ..
Click to expand...
Click to collapse
once it completes "loading apx mode bootloader" this is when yr tab should vibrate and display the white text "acer a500 apx mode" which is what
leads me to believe that for some reason its waiting for the driver even when it seems to be installed already.....this is where i think the problem lay.
The only other tool that may work is timmydeans v4 it uses apx mode as well but will roll u back to HC, it also repartitions and 'resets' your tabs file system as alot of tabs have got stuck on "formatting partitions" with the flash...hopefully this won't happen to yours but you'll find out after running nvFlash tool...
apxFlash has never been able to pick up the fact my tab is in apx mode, it, like afterOTA relies on adb to gather the required tab info, and of course if it doesnt recognise your tab it doesnt know its connecteD!!! At least afterota recognises this by the fact the "unbrick" menus are not greyed out...
The only other thing i might suggest is putting yr tab in apx mode manually -
Turn tab off
use a paper clip to push and hold the reset button
then press and hold the power button UNTIL the power Lite comes on
count 3 secs and release
then after another second release the reset button
might seem strange thing to try, but you never know it may just 'jog' something into life
Yes ... I'm using Win7 64-bit.
When I plug the USB cable into the A500 ...
1) Acer USB Boot-recovery driver shows up in Device Manager ... listed under USB controllers
2) An APX icon shows up in Devices and Printers (not in Device Manager) ... it's listed under a category call "Unspecified"
When I unplug the USB cable, both 1) and 2) go away.
For manual driver install ... are you referring to:
C:\Program Files (x86)\Acer Inc\ACER ICONIA TAB3G\Win7\ADB\x64\android_usb.inf
-or-
C:\Program Files (x86)\Acer Inc\ACER ICONIA TAB3G\Win7\USB_ethernet_rndis\x64\acer_usb_ethernet_rndis.inf
-or- something else?
I have an older laptop running Win7 32-bit, so I'll also try that too.

something else, lol hold on....i'll just go check
I tried the paper clip / power button trick ... and then back to AfterOTA on Win7x64 ... no luck. I also tried AfterOTA on my laptop (Win7 32-bit) ... exact same problem.
ok this is where things get even weirder...and from memory it was a real pain to get this apx device installed....windows kept wanting an inf file but i'm positive that in the end i got it to install from a folder - i just cant remember how????
I cancelled the hardware wizard from doing its thing
then in the next window there are 2 options
let windows choose or let me choose - something like that
i kept trying let me choose and got nowhere
then i think i tried "search my computer" and chose the C drive - i'm sure it found the right ones that way
and i think i uninstalled all acer and android drivers, rebooted and reinstalled them before i could get any joy....i know it took a good 5-6 hours of mucking about - until finally something worked...
and yes def give 32 bit a go before we get too carried away!!!
oh no... i think i've jsut got stuck in apx mode...

then the only other thing to do is a rollback using timmydeansv4. run the tool without yr cable connected and wait for the instructions to put yr tab into manual apx mode - you wont have to worry bout that seeing as you're in it already!!! connect yr cable and click OK - enter cpuid and wait 10mins for it to do its thing...it won't take any longer than this -
let us know how you go!! and good luck m8
Where can I find timmydeansv4? Google search isn't finding it.
Thanks

i renamed the Acer Folder in Program Files
I then put my tab in manual apx
when the driver went to install
i cancelled "skip searching windows update"
in usb controllers an acer picasso boot recovery is listed
AND in Printers and Hardware the APX device is there - i didnt do anything with it at all
I fired up afterOTA but it couldnt see my tab
So I used civs V8 nvflash pckg
tab went into the proper apx mode with the txt displayed
it flashed and now running v8 and cwm 1.7.3
I did this via HC 3.1 win7 32
That worked !!!
I followed your The Chickens Guide to Flashing the bootloader manually after installing the USB driver from the Acer support website. Now I'm back to ICS without having lost any of my data or settings.
A couple of noob questions:
1) Would an ota update from Acer wipe out the newly installed V8 bootloader & Thor 1.7.3 recovery?
2) What's the most reliable way to root ICS?
Thanks so much for your patience with my problem!

Oh m8 thats made my day:laugh::laugh::laugh::laugh: rapt for u!!!
So u think it was the drivers??
1) don't know, we haven't recd an ota to find out - but in my experience nothing wipes unless u do! An EUU may do it or an official updaate.zip.
2) icsroot by blackthund3r google it
3) if u install a custom rom you will need to do a full wipe and format via cwm b4 and after flashing this includes Jr internal storage else all sorts of glitches happen.
Your welcome., as I said its been a problem with no real solution, awesome to know it that in the end it finally worked
I'm not sure it is the drivers. I installed Acer USB Driver v1.00.0524 (2011-10-06) from the Acer website. It appears to be the same version installed by AfterOTA. Maybe it's something else in AfterOTA that just gets hung up on a combination of hardware and software that wasn't anticipated? I'm sure gersma couldn't anticipate or check out every combination.
I'll try ICS Root.
Thanks again for all the help.

If the usb connection is disconnecting here's a few things you can check.
Both sets of drivers are installed. The Acer ones and the android ones.
Try a different usb cable.
Win 64 bit has issues try xp, ,vista or win 7 machine.
If still no joy try civs manual flash or Ubuntu.
Sounds like a driver issue so check those first.

Thanks so much for the reply the drive i have is Acer USB boot recovery drive and before that Picasso was visible .. there is just one driver how can i get two drives here? i have read many forum and the links they gaved is Just one two drivers, one was Picasso and the other was simple that i mentioned at first but the Device Manager just shows one (Acer USB boot recovery drive)
Three cables are changed but all it happens that it stuck at partition fomating or flashing recovery
Also like to mention that i Used AFTEROTA which shows the status under
Driver - OK - driver installed
USB - ERROR connect usb cable and enable usb debugging
(how can usb debugging be enabled when tablet is totally dead)
In the cpuid guide in my sig there's a download for adb/fast boot drivers. You must have these installed.
Was yr tab running ok before all this?

I have followed ur link and this is what i see
DRIVERS
Acer Support for Acer APX/Fastboot/Recovery Drivers
Android SDK for the adb/USB drivers - You can d/l a mini zip containing just the adb and fastboot drivers attached to this post "adb_fast.zip"
i went to ace support and download the honeycomb first version but the adb_fast.zip doesn't have any driver its a program... Kindly suggest where is the other driver
Sir Kindly reply i am waiting for your suggestion.:crying:
Hi there,
So I did something really stupid and I wiped my phone while in recover mode trying to install a new ROM. And now I'm stuck with a useless phone that can only go into TWRP and Firmware Update Mode.
I've tried every method to unbrick my phone, and have a previous thread on this forum trying to get help (http://forum.xda-developers.com/showthread.php?p=48914581#post48914581), but nothing is working.
My question now is I'm running TWRP 6.3.2.2, If I buy a USB OTG cable and put my rom files on a USB thumbdrive, can I then install the rom from the usb? If so, where in the filesystem does this usb storage show up?

I believe only TWRP 2.6.3.4 can support OTG (I've been happy with it).
I think you may have to ADB push the files from PC over while in recovery (may need to look around).
hello
i have a problem with my g928f
my issue is that it can not be regognized by the windows
i have tried at my desktop with win 10 and at my laptop with windows 7 and at both says unknown device,
i have tried everything i know of
unistall everything from the pc regarding samsung drivers
install it again , nothing
install smart switch , nothing
install kies, nothing
run odin , not even see the phone at download mode
made factory reset from recovery , nothing
charge is working just fine both from pc and my wall charger
i tried mhl hdmi and nothing happened
tried just now otg cable with a usb drive , again nothing

i cann't flash the stock rom because odin is not see it also
is it possible to be a rom problem????
i can't flash the stock one because of the usb issue
but i think i can download another lollipop rom to give it a try.
Have you made sure that it is set as MTP?
Setting - Storage - USB.
Check if the device gets connected in Fastboot mode. If it doesn't then it would be your USB.
sideload is not working either
usb is brand new and original.
is there a way to flash stock rom via recovery?
So, after a long story about Link2SD f*ck up my storage, i decide to flash a custom rom . when in twrp I accidentally delete everything and receive message "not os install...".
