Hi
im kinda of a novice in flashing the tab, but i did anyway.
Now i have hit a snag, and it says that it cannot mount the internal sd card, so my tab keeps booting to recovery all the time. i try to wipe data or format but it says on different actions i try....
E:unknown volume for path
e:unable to process volume.
how can i get it to boot?? i do not have a back up
please advice
thanks
Try pressing Home button many times until it boots back.
or:
I havnt tried this before since im doing heaps of researching myself to get a recovery for my stock GT. You can you try and use Kies as the software comes with an emergancy system recovery option. That should restore your galaxy even if your in recovery of some sort. I havnt tried it myself but thats similiar to odlin.
Hello. I have an Acer Iconia Tab A200, and recently I tried a factory reset. However, due to my meddling with system files, it won't reset.
I've tried to do a hard reset (Power on, Volume+, Orientation lock switch) but it says the following:
Erasing Userdata...
Erasing Cache...
It then reboots, and does nothing. It hangs on the Acer logo.
When trying to go into recovery (Power On, Volume-), it says the following:
Erasing Cache before SD update...
SD update cmd: recovery
--update_package=SDCARD:update.zip
Booting recovery kernel image
Recovery verified fail ...
Now, I mentioned that I meddled with the System Files. Here is what I did:
1. Removed unwanted Vendor Apps
2. Removed the DEFAULT LAUNCHER <-- I think this plays a big part in this
3. Placed a CUSTOM LAUNCHER in the VENDOR APPS FILE
4. Did a FACTORY RESET
My brother is more techy than me, so he tried to fix it. However, he somehow re-locked the bootloader and even replaced the bootloader with a newer version.
I talked to Acer Support claiming it's system files corrupted itself, but they won't fix it unless I also pay to fix my cracked screen. I'm willing to do so, but hey, I'd like to see if I could save $120. I don't mind the cracked screen.
NOTES:
The Acer Iconia Tab A200, along with their other tablets, has a USB port. I can probably load stuff from there somehow, but not sure.
It is a 16GB model with a 32GB Class 10 MicroSD card in it.
Any ideas? All help is appreciated.

Do you have access to any a200 Update roms? Sometimes, you can pull the update.zip from the rom, place it on your ext sd card, reboot holding Vol+ and PWR, and it might install.

I have searched for some A200 ROMs, but can't find any that work using that method. I'm open for ANY Acer A200 official ROM, then simply updating using OTA. I tried an Acer A200 Recovery Pack I found. It is the exact stock Honeycomb image, but it didn't go. It always says recovery verified fail. I cannot unlock the BootLoader either.
Stockimage flashable while having bricked /DATA Partition
Hi Vuciz,
do you still have the issue with your bricked A200 ?
I got the same problem with mine, the only solution was to send it to repair, it seems the storage controller chip has some bug which destroyed the /DATA partition unrecoverable.
if you need to revert your Tablet to an locked bootloader you have to download an StockRom and modify it by removing the partition check (called "assert") in the update script.
please send me an message if you need further assistance.
regards and good luck with your tab.

Yes I do. However the screen is also cracked so they want me to pay for that. Which I'm unable to do at this time.
anything I do, fails

I also have this tablet. I bought it for 20 bucks because the screen was cracked. replaced the screen and then found out that the bootloader was trashed. I've done almost everything I can think of to fix it. Used APX mode to get UID from ubuntu, tried to use that UID to get sbk, got the SBK and then tried using blackthunder's tool got connection failure, tried using babsector same thing, even went in ubuntu, with tablet in manual apx mode for all three and when I attempt to reflash the bootloader, all I get is that command failure message with a nvflash connection failed nv error 0x30011 message and when that happens in windows, the tablet disappears from device manager, and in ubuntu when I run nvflash with the sbk function --sbk XXXX and so on, I get the command sent failure message, and then when i rerun lsusb, the nvidia device that represents my tablet in apx mode that showed before is no longer listed unless i reboot the tablet in apx mode again. If i boot it normally, the acer logo appears and then goes to the little animation and then the iconia tab screen and thats it. I've tried attempting to flash the bootloader from that screen which i know probably wasn't going to work anyways. If anyone has any advice on something I've missed, or anything that could help, i'll all eyes. thanks in advance.

Just so you know, I was never able to resolve this issue.
Hello,
I search help for my Acer Iconia Tab A200.
During a flash with TWRP, it block and I have to set my A200 off using Power.
And then, my A200 don't work, don't vibrate.
I try :
Reset + Power : nothing, no vibration
Power + Vol- : nothing, no vibration
Power + Vol+ + switch : same result
Connected to PC : adb devices : nothing
All commands adb or fastboot : waiting for device
I don't know what to do...
where can I send my Acer tablet to fixed stuck on bootloader
hello I have an acer iconia 200 stuck bootloader cant find anyone to fix it. Acer wont touch it unless its under warrenty! my 90 day store warrenty has been way past! taken to 2 local computer tech both told me I needed to send it back to acer but I cant! so what can ido i or where can I send it?? anyones time and effort would greatly appreicated!!! thanx for your time
I just recently tried to downgrade my A500 using downgrade_not_stable.zip on a non-formatted SD card and after it updates it is stuck on boot screen and the message is
"Not legal !!!!!!! abort
Warning: The blob package is not official ~ Abort!
Boot verification failed ..."
When i turn it back on, it only has the words:
"Boot verification failed ..."
In red it the top left corner. I have tried the solutions from other threads here and none of them worked.
Is there any way to for me to fix my tablet or does the SD card have to be formatted or is there another ROM that would work on this tablet.
Thanks in advance for any help
If you haven't tried it yet, try just removing the sd card and rebooting. If that fails alone, then try getting into the recovery via power button + vol down and see if you can get into that. If you can get into the recovery environment you should be able to use one of the many recovery methods or roms to get yourself back in shape.
Hi
I have a i9505 that all of a sudden stopped booting. If I turn it on, I see the "Samsung Galaxy S4" logo for a couple of seconds, then the screen just goes black.
If I try to boot while holding down "Vol+" and "Home" (recovery mode) a blue line of text at the top says "recovery booting..." but it never does, it just stays stuck there and nothing happens.
Download/Odin mode seems to work, so I tried to flash a custom recovery. Tried both TWRP and CWM Touch, but same result: when I try to boot into recovery it just says "Recovery booting" at the top and doesn't do anything. Only difference is that it detects that the recovery is non-stock and warns me about it under the "recovery booting" line, but the result is the same: completely stuck.
The next step I would try is to flash a full firmware, however I understand this will wipe my data partition, is this correct?
The truth is, I'm actually more interested in recovering the files that are on the phone rather than to unbrick the phone, so before proceding I wanted to know if anyone had any idea why recovery is not working or has any idea on how to recover my data in any other way.
Any suggestion, even the most desperate ones, are welcome.
The only data that will be deleted is app data. Anything stored on the internal memory should be fine.

Thanks, I tried going forwared with the full flash, but Odin always gets stuck while flashing "system", at different moments but always near the start. I have to pull the usb plug and battery to reset the phone.
I have a suspicion there's some deeper hardware issue here, maybe memory corruption, that is preventing me from either booting or completing a full flash. Does that sound reasonable? Any options you can recommend, other than just throwing the phone in a volcano?

The flash problem may also be caused by the USB cable or the micro USB port on the phone.
The only other option is to take it to a pro and Jtag it or something.
I tried to go about rooting and what not with my Galaxy Tab A 10.1 w/ S-pen (sm-p580). I was following the following guide:
https://forum.xda-developers.com/ga...covery-official-twrp-galaxy-tab-10-1-t3473023
Everything seemed to be going well. At the end of it all I went to reboot the system and now I appear to be stuck in a loop. TWRP tries to load and then I think it reads that if fails to mount data. The system reboots again and then it I get a message on a black background saying "Verification Failed" and there is a button to factory reset the tablet. When I click that button, start the cycle again starting with the failed TWRP.
At this point I will take any advice that will just get the tablet working again (with or without root/TWRP). I do not have any data that needs to be saved on the tablet. If it seems like I have left any details, please ask away as I will fill in whatever info I can. Thanks for all the help. Hopefully I didn't break my tablet.

Boot to TWRP, use the FORMAT DATA BUTTON to Format data then immediately flash SuperSU.
Reboot.
Your device should boot after a short while, be patient.

Thank you for your help. I was trying to boot into TWRP and was having trouble getting into that. I tried one more time after your post and fortunately was able to get into it. Everything is working great now!
