[Q] Stuck at "Enter your password" screen - Acer Iconia A500

Hey guys....i really do need help on this.
i've manually flashed ACER_A500_4.010.41_COM_GEN1 update.zip on my a500, when finished and rebooted, a screen asking me to enter a password appear but i don't know the password.
I've read through the forum and tried almost everything suggested;
1. Hard reset / soft reset - nothing happened
2. Revert to HC3.0.1 using APX - unable to go into APX can't set the tab into usb debugging.
3. Flash HC3.0.1 update.zip - can't flash, droid with yellow triangle.
Any idea/suggestion?except to send the tab to acer support.
Thanks

apparently the only way to fix this is to completely wipe ALL your data/cache
if you have the unlocked boot loader then see http://forum.xda-developers.com/showthread.php?t=1969106
if you have stock boot loader then the only way is to use the toggle rotation lock method....its fiddly to get right bit tab will display text wiping use data and cache when u do...keep trying

Alright, finally able to erase userdata via fastboot, which i've discovered after posting this. now the tab is back in business.

[Q] A500 bricked after failed device encryption

Hi All,
Need your help. I tried setting up a corporate Exchange Account on my Iconia (rooted, running Honeyvillain 1.05). After set up of the account, I was asked to encrypt the table (policy from the corporate server). I followed the prompts to start the encryption process, entered a password, and then the device rebooted. It then was stuck on the screen with "Android" on it. I waited 30 minutes, and nothing. I forced a restart and then was presented with a green android (with a belt?) and prompting me for my password. After entering the password and hitting "OK" it would then immediately reboot and stop, again, at the screen with the white "Android". I tried wiping and restarting but nothing. I then tried installing a different ROM, but again was prompted for my password. This time (virtuous galaxy rom) it didn't actually restart, but just froze on the screen with the green android robot with the belt looking thing. I've tried running the unbricking process using the update.zip method, but still cannot get past the screen prompting me for my password. Would love your help with this! Am I out of luck?
Thanks,
-T
I use encryption with my tablet, and switched from various stock roms without problems, but I even didn't try with the custom roms, surely it will fail and loose all my data. The only thing I can think for you repair your tablet is to try to flash a stock rom and see if it boots, if not, then you have to erase everything from the tablet. There is a post saying to boot holding the power+vol up keys and then move the lock switch several times on and off, so it deletes everything on the tablet like a hard reset.
After you do that I will recommend stick with the stock rom (rooted if you want, it doesn't disturb the encryption) and encrypt the tablet again, it took quite a time to do it, specially if you have many data in the internal memory.
Hope it helps you.
Hi There,
Thanks for the reply. In the meantime, I actually found some instructions on how to do a factory reset (volume+ and power, then release power, then toggle screen lock twice) and I managed to revive it! I had previously tried installing the update.zip mentioned here: http://androidforums.com/acer-iconia-tab-a500/345419-un-brick-acer-iconia-tab-a500.html, and after a factory reset, the tab booted into this stock EMEA ROM.

[Q] Phone stuck on HTC screen?

My phone is stuck on the start-up HTC screen, the one with the green "HTC" logo non a white background.
I was just changing my font to "Cees Hand Regular" using Font Changer and it was not my first time using this application. Every font change requires a reboot, and when I did so my phone got stuck on the start-up screen.
I'm currently running the latest stable version of Cyangonmod if I'm not wrong, and my phone is still able to enter bootloader mode.
I've already tried Googling around for answers and there were some saying to reflash a new rom. But how can I do so if my phone is in such a state? I also tried pulling out the battery to cool and even cleared my memory.
Can someone help me with my problem? Any help or replies is very much appreciated!
If you can enter bootloader mode, you can enter recovery (Clockworkmod) and can flash a ROM again from there.
Enter bootloader, wait for the file scan to get over, then use the volume keys to navigate to RECOVERY, and press the Power Key. Phone will restart in Clockworkmod. Here, perform a wipe data / factory reset, format /system under Advanced, and re-flash the ROM again.

Acer A200 Bricked - Can't Recover

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.

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.

[Q] a500 with forgotten password and unable to restore unrooted tab

A coworker has given me an a500 to try and restore to a working conditiion. Here is the story I was given... Tablet was working fine but he had a pop up informing of an update. He ignored it for awhile but finally let it update and after it rebooted he was presented with a password screen. He has no clue what the password is. I don't know what the tablet was updated to and to my knowledge it is not rooted.
I have tried erasing user data by holding down volume up and power and toggling the screen lock switch back and fourth after the tablet vibrates. Tablet displays
Erasing Cache before SD update.
SD update cmd:recovery
--update_package=sdcard:update.zip.
Then displays in red Secure boot: image sos checksum fail. I have had a couple different update.zip files on the sdcard when trying this but none are successful and it never seems to erase user data as it always asks for a password.
I have also tried an EUU update and putting the tablet into apx mode manually but this to fails. I was able to get the CPUID off of the device using a thread on this forum and an Ubuntu installation.
I have poured over numberous threads and tried many things over the last couple days and have had no luck. I am look for some help in either just erasing user data so we can go through set up again or downgrading/rooting or what ever it takes to get the tablet in a usable state again. I have a little knowledge of rooting and using adb and have never tried ubuntu until this weekend.
Thanks

theres a thread titled "will pay to get my tab fixed" actually there are 2, but in one of them I think the problem was resolved....I'll post a link to it if i can find it
oh... u say u used an update.zip - make sure it isnt still on yr sdcard???
out of interest what happens when u press power + vol UP - just wondering what bootloader the tab has...doing this will tell us
what part of apx mode failed???
i guess you've seen the SOS/LNX checksum thread???
you have a serious failure here, but hopefully not irrecoverable....fingers crossed
Hi, Thanks for responding. Its taken me a while to get back to this because of Thanksgiving and a project at work.
The update.zip is on the sd card. How do I move it the tablet?
When I press power + vol up the tablet vibrates then displays acer on the center of the screen. It then displays in the corner of the screen:
Erasing Cache before SD Update...
SD update cmd:recovery
--update_package=SDCARD:update.zip
Secure boot: image SOS checksum fail!
With the EUU update I run the PBJ20upgrade.exe. I then let it time out and manually put the tablet in apx mode. I then put in my CPUID and hit next. The tablet vibrates and displaces entering Acer download mode but the PBJ20upgrade.exe program displays that the upgrade process failed as soon as it vibrates.
The EUU update i tried was titled EUUs_SBK_Acer_A501_0.017.01_PA_ATT
Thanks again for the help

Constant restarts

Hello
Since this morning my Note 3 has died. I went to turn it on and it did not go beyond the initial Samsung boot screen.
I have already tried almost everything:
- Enter in recovery mode and make wipe dalvik and cache
- Enter in recovery mode and make wipe factory reset
- Install a new ROM for Odin
When Odin finishes, he gives me the PASS in green as all correct. I start the phone, enter the initial configuration screens, let me put the language, wifi, Google account but when the automatic configuration of the applications starts, it restarts and loops in trying to boot, but does not pass the Samsung logo.
I tried to install the ROM again, in case there had been any problems during the installation (despite giving the PASS in green), but it does not work.
The only thing I can think of is to put another type of ROM of those in which the option Re-Partition is marked, which I think is more exhaustive, but I'm not clear what kind of ROMs those are.
I would appreciate any help with the ROMs with Re-Partition, or any other suggestion that you could give me, to see if I can resuscitate it.
Are you performing a factory reset after flashing a stock ROM with Odin and before the phone boots the stock ROM for the first time?
but when the automatic configuration of the applications starts, it restarts
Reads as an app or something is the problem .
Thank you very much for your responses. After searching a lot, I found a ROM of 4 files + PIT. After installing it, the phone works correctly.
