[Q] Custom ROM, stuck at boot animation... - Acer Iconia A500

I wanted to run a custom ROM on my A500 (first attempt at installing custom ROM), but i'm now stuck at the boot animation.
I downgraded my A500 to 3.0.1, rooted, installed clockwork mod, upgraded cwm to 1.5. So far so good.
Then i downloaded thor rom v12, copied it to the external sd card (by putting it on USB thumb drive, transfer to tablet, copy to external SD using file explorer - something tells me I'm going to need to pick up an sd card reader for my computer)
Rebooted into recovery, wiped everything (had nothing of value installed yet), and then chose to install zip file, chose thor_rom_v12.zip on external SD card, it started installing - looked like it succeeded.
Reboot tablet, and i've been staring at the boot animation (electric blue pulsating android with spinning gears on it) for about 45 minutes.
How should I proceed from here? Any idea what I did wrong?
Thanks

Hold the power button down and see if you can force it to shut down. I dont think itll turn off but its worth a try. You could also try the hard reset button (pin hole on the side of the tab) if the reset works than you should be able to boot back into recovery. If not than youll just have to wait till the battery dies.
Once you eventually get it turned off than try booting into recovery and do a full wipe and reflash the rom. I have a feeling the file you downloaded is corrupted though. if this is so than your tab probally wont boot up again.
At this point id redownload the thor or another rom and than try flashing that. You'd have to get an sd reader since you won't be able to transfer the files through your iconia again. If you can manage to get a clean download on your micro sd somehow than i'd skip straight to this step and start redownloading the rom right now.
BTW these are just the things i would try from knowing what I do about android. I haven't had any issues with my tab yet so I havent looked for solutions for this it, but ive dealt with other boot looped and soft bricked devices.
I'm sure if you do a search you'll find something.

[Q] Bricked!?!?!

I've heard about how it's pretty much impossible to brick the nook... Mine seems about as useful as a brick though. I was trying to set up a dual boot following these instructions. Basically, I had HC installed to the internal memory. backed it up, formatted system and data, then flashed update-nc-stock-1.2. CWM said that was successful. Then I rebooted with my CWM SD card out. Screen said "read forever" or whatever, then went blank. I waited for about 5 minutes, and pressed the power button. The screen went from an 'on' blank to an 'off' blank. Since then, I haven't been able to get it to turn on at all. Just an 'off' blank screen with no signs of life, even with charger cable connected. Tried it with CWM SD in and out. None of the buttons seem to do anything...
Thanks in advance!!
I'm pretty new to the Nook having just got it today, but I did some reading prior to attempting anything to see how easily I could back out if I had to.
Have you tried basically starting over (ie. Let go of the multi-boot dream for a bit and get back to basics)
You know, take a SD card, use diskimager to put the clockwork 3.0.2.8 image on it with the CM7 full ROM and boot to that, then format system, data and cache with clockwork and finally install the CM7 zip image (and gapps I guess) just to get going again.
If it all works, maybe take another run at whatever you are trying to do with the multi-boot stuff.
Thanks for the reply.
Sounds awesome; problem is I can't get the thing to do ANYTHING. boot period, into recovery or otherwise. I plug it in and it displays nothing - no 'wait 15 minutes and try again'. Just a black screen no matter what I do. I have an SD card with recovery on it, and i've tried making it do something with or without the SD card. No luck.
Good luck with your nook; I had really been enjoying mine.
So holding the power button for 10-15 seconds doesn't do anything?
Or when you plug in the power does it try to boot?
I mean in a complete worst case scenario you could grab yourself a T5 and open it up, disconnect the battery, and then reconnect it.
Then something is wrong with your Recovery SD card, as no matter what, hardware dictates that it reads the sd card first. The problem with what you did through dual boot methods is you resized partitions. So even if you do back out of all of this, you're going to be losing space unless you setup dual boot.
Recreate the CWM recovery card, either redownload the image and reburn it. Find a different one or something else, because it should load on startup.
Thanks for the help!
Reformatted SD again, then tried powering up with the power cord unplugged. Apparently it won't boot into recovery as long as the power cable is in, and whatever the boot was on EMMC was messed up. Happily running stock 1.2 now, next step, dual boot with HC!
Anyone know how I can delete this thread as it's pretty unnecessary?

[Q] Bricked Iconia...

I guess I bricked my iconia...
I installed Recovery, etc. But when I rebooted my device it starts up, and shows my initial display screen. But it locks on the display (it is past the Android, and Acer screen).
So I tried to recover the device using the unbrick procedures described in this forum, and others. But it seems whenever it tries to process any update.zip file including the unbrick the little android man either stops turning or displays a sign indicating things did not work out as they should have.
I have clockwordmod backup from my system. How do I use that backup? When I use my phone the device automatically boots into xrecovery and allows me to restore. How do I get that with the Iconia?
first of all your device is not bricked as long as you can boot into any type of recovery.
second you obviously have cwm installed, but anyhow even if you don't have it i hope you have an external sd-card.
dl any of the stock rom's from the dev section, basically best is to choose the rom made for your country.
extract the update.zip and put it on your external sd-card.
then install it with cwm if you still have it, or with acer recovery (volume - and power simultaneously until the recovery text shows up).
and then take it from there.
also good idea is to clean dalvik cache and data cache before restarting if you use cwm.
then you can reinstall root and cwm.

Thanks... The problem is I can't boot into anything.
How do I boot into cwm? I can't boot into the operating system as once it hits the display screen with my picture the system freezes and tries to power down?
I have been playing around with acer recovery, but all of the updates I downloaded will not load onto the system. It tries to install, gets about 1/3 through and then gives me an error.
Hence why I was thinking that maybe my backup has something?
push volume - (left volume button) first and power and keep your fingers on it until it displays the recovery text message on top left of the screen
If you are getting into recovery. And flashing. A rom give you errors or does not complete. This issue is a bad d/load.or a bad currupt SD card.I would say format your SD card again.redownload the correct rom again.don't use a download manager.then decrypt. Unzip then put the update.zip on your SD card turn off your tab install SD card.
Reboot
Holding down volume up and power until you see the 4th line of txt. It should take you to cwr. Or flash your device
good luck
Yep.. use vol-down and power to boot into cwm. Keep holding vol-down until you see tiny white text in upper left corner.
Then do full restore. When it's done, if you don't see "Backup Succesfull!" message, you'll need to restore flexrom from the advanced restore menu. This is because it failed trying to restore .android_secure.img and caused cwm to restart before flextrom was restored.
Alternatively, you can delete the .android_secure.img file from your backup set before doing the full restore.
Good luck.

Thanks guys for all of your feedback.
However, when I hold down the buttons you mentioned I do get those text items you mention. The problem is that unlike my android phone it does not pop up the recovery menu. It goes straight into the Acer Recovery procedure (The android with turning gears).
Could it have been that upgrading to a specific ROM the recovery procedure is shortcircuited????
What I am trying to figure out is how to get the recovery menu.
Same deal!
I have the exact same issue. The Update.zip will not take and the Android Gears screen gets to 1/3 before the yellow triangle. Any further help would yield loud THANKS!
your update.zip should preferably be those 3.1 full. cos I believe it does not check anything for it to fail.
Thanks Kenny that does help and explain a few things.

[Q] A500 Stuck on Android Screen

I have an A500 that was originally purchased in Thailand. I contacted Acer Thailand and they provided me a recovery package to install. I put this on a FAT32 formatted Micro SD card and it installs, but when the tablet reboots itself it gets suck on the screen with the silver "android" logo.
I've gone also some of the advice in this thread as well: http://forum.xda-developers.com/showthread.php?t=1874345.
So far I've tried 3/4 recovery zips provided (41-124-01, 41-125-03, 41-203-01) with the same results. Rather than simply trying to load recovery ROMs at random hoping one magically fixes the problem, what I'd like to do what I would like to do is completely erase the flash on the device, and then try reloading the recovery ROM.
Is there a NON-acer recovery tool I can use to blow away everything that is on there now (and presumably, the corrupted bits?)

I ended up getting it booting up into Jellybean. First I tried restoring as mentioned above with the SD card.
This next part, I believe is the key as the device revived after this step. I put it into a bootloader restore mode by powering on with volume down and flicking the screen lock switch once the device vibrated. After this, it continued with the tablet setup mode and booted into Jellybean.

Fixed bootloop, back in bootloop. Crap.

How it started: I use a NC with mirage 7.2 flashed to the emmc in my car. It runs Torque to display engine data, and is switched in and out of sleep with the ignition. Two days ago I started the car and got the low-battery "exclamation point" icon thing, so I figured the charging cable must have come loose*. I took it all out and left it charging overnight, but when I went to boot it in the morning it was stuck in a cyanoboot loop. I couldn't power the device down or enter emmc recovery. When I completely unplug the NC I can't do anything, the screen remains black no matter what I press, except it flashes white every 5 seconds or so. If I manage to plug it on, get to the cyanoboot loading screen and unplug it while holding the power button down at the right time, I can sometimes get it to power off completely.
What I have done so far: Tried various recovery SD methods, none of which worked. Wiped cache/data/system, factory reset, tried loading 7.2 again over the top of whatever is left in there, lol. Basically after it first happened I probably made a big mess of the file system in a desperate attempt for some kind of stability. I tried this recovery SD: http://forum.xda-developers.com/showthread.php?p=25354258#post25354258 ; section A10, and managed to get into CWR. I've never felt such joy in my life.
What finally worked: I repaired the 2nd partition with the help of this thread: http://forum.xda-developers.com/showthread.php?t=1759558 . I did not repair or format any other partitions though. After repairing the partition, I did a factory reset and flashed mirage 7.2 and gapps back onto the emmc. Before I rebooted, I swapped a clean SD in but it still went back into the bootloop..BUT...when I put my recovery SD back in it booted into 7.2! I set everything up and was happy to have it running again. Battery level was at 88%.
What made it stop working: I was testing to make sure the NC would enter sleep mode when disconnected from power, so I unplugged it. Everything went black, no "sleeping" screen, just a hard shut-down. I powered it back on and I'm now back in a cyanomod boot loop.
So...any ideas? If there's a way to completely wipe and reinstall everything I'm OK with that. I've never used ADB before but I'll give it a shot if someone can lead me in the right direction. Thanks in advance.
*I'm using a 2amp USB car charger with a modified data-looped cable for a/c style charging in the car. I know the supplied nook cables are prone to going bad, and this may have happened with the vibration of the car and all. Not sure.
Little update: I can sometimes get into TWRP by selecting the "normal emmc" boot from the cyanoboot screen. I don't understand how that's possible, as I flashed that on my original install of 7.2 months ago. Guess I need to figure out how to completely wipe and re-flash everything.

To completely wipe and reflash everything, do the other two zips that you said you did not do from my partition repair thread.

No luck with that. Here's exactly what I did, so tell me where I might be going wrong:
1) Burned an image of the 6.1.0.2 recovery onto SD, then put the (2) recovery zips and the (1) format zip as well as the mirage 7.2 and gapp zips onto the SD.
2) Booted into cyanoboot, it took a few tries to get out of the loop and into CWM. Note that I can't power on at all unless it's plugged in. As soon as I unplug the NC it turns of except the screen will flash every 5 seconds or so. Once I got into CWM, I installed both partition repair zips, starting with the 1-4-5-6-7-8, followed by the 2. Rebooted. There were no errors at all.
3) Again it took a few tries to get out of the bootloop and into CWM. Installed the format zip and rebooted again.
4) Installed Mirage 7.2 and gapps and restarted, but went straight back into bootloop. I know that the rom requires a clean formated SD card, so before rebooting after I installed the zips I took out the SD card, formatted with SDFormatter and reinserted in into the NC.
I'm beginning to think this is something hardware related. :crying:
Sounds like there might be some bad data in emmc, I had this problem before and fixed it by formatting everything , even emmc and wiping dalvik cache. Then boot off a SD card using the latest cwm.

It is possible that your partition table is messed up. The only way to find out is to boot to recovery, connect your USB cable to the PC and run ADB. It is also possible to make a CM bootable SD and use terminal emulator to check it out.
Once you get ADB shell or terminal emulator working, type the following command:
fdisk -l /dev/block/mmcblk0
It should say 965 cylinders, 4 heads, 63 sectors.
If it does not, we need to do a manual repair.
You can also abandon emmc and just run off SD.

Urgent help needed I bricked the unbrickable nook color

Summary:
I bricked my sister's Nook Color. She bought it refurbished at a pawn shop for cheap and everything was working until I told my sister that I could root the nook and put an android rom on it. My biggest mistake ever.
I looked at a lot of forums relating to the problem and it seems like there isn't a fix. So basically I got to the point of having CWM working.
All was going so well and I decided to flash eyeballer's cm-9-encore-20120904-0700-unofficial.zip on it. The one on Goo.im. After looking at screenshots of CM9 I was impressed.
I did the factory reset on it and wipe the cache, I flashed the CM9 and it was installing and it seem that it was taking a long time and then the nook turned off.
The biggest mistake that I made was that I formatted the boot , I'm a noob, I figured I wasn't the only one so I came across a thread here http://forum.xda-developers.com/showthread.php?t=949699
I thought that CM9 got installed and when I went to turn it on, nothing whatsoever... It doesn't boot no more.
I tried putting the 1gb bootable CWM on a 1gb sd card with Win32 Disk Imager and the Nook didn't boot from the SD card either and I also did the same with an 8gb.
When I go connect the Nook on the computer it searches for a driver called Omap3630 but it doesn't install and it seems to disconnect itself.
I am was looking for more threads and found out that I'm in a similar situation as a user called Jiv_au here,

The problem is that you formatted boot, and CM does not include all of the needed boot files if you formatted boot. You will need to flash the stock firmware back onto the device, and then you can proceed to flash whatever ROM you want on the device, LINK.
I am not sure what version bootable CWM you are using, but download and flash this one,LINK. Since you saw the Omap3630 driver prompt, it does mean that it still is alive and attempting to go through the booting process. As for getting it to boot from this card, you will not get any visual indication that the device is on or not, the screen will stay dark if it’s on or off. Since the device might have been on this whole time I recommend that you fully charge the device before proceeding forward. With no USB cable connected to the device, press and hold the power button for 30 seconds, then insert the SD card, then press and hold the power button for 5 seconds to turn it on. It should boot into the CWM recovery, if it does not press the power button for 30 seconds and try again. It might take a couple attempts, but you should be able to get it. Once you get the device to boot, wipe data/cache, and flash the stock image, and reboot the device. Once you have a working device, you can then boot into the CWM card, and flash the ROM that you want.

You gave me a bit of hope but its not booting. The nook is dead... thanks for the help.
edit: I heard that pressing Power + N is like forcing a shut down so I hold those for 30 seconds and then put the SD card in it No boot.
I tried it again and put the Sd card in it and then press the power button still nothing. I believe this is definitely dead. I wish she had bought it at the B&N store. I think I'm getting her a Nook tablet. I owe it to her.
