My Iconia has CWM installed. I used it a while ago to install the leaked ICS rom. I tried to install the most recent (official) ICS rom. Now my Iconia will not boot past the Iconia logo. I've loaded CWM and formatted everything and reinstalled the official rom. No go.
I figure at this point I have to use nvflash to install a new recovery image and rom. Could somebody tell me how to do that and what files to get?
Thanks
Before doing anything else have you tried wiping cache and data? Has worked for me when a rom wont boot. Have you still got cwm can you access it? If no cwm you can accomplish this by holding power and volume up then toggle the rotation lock.
Yes, I have access to CWM. I have tried wiping everything. I even successfully installed a new rom. The device still will not boot past the Acer logo.
I booted wit hte method you described. Two messages appeared in quick succession, "Clearing data..." and "Clearing cache". After the cache message, the device just sits there doing nothing at all.
Previously I had the data partition encrypted. Could that be causing trouble?
did you install an ICS bootloader?
I'm not sure. That is why I created this thread. I'm looking to get the recovery and OS image necessary to get this device working again.
As the previous poster noted, have you switched to the ICS bootloader? When I flashed my A500 with an ICS rom it too got stuck in a bootloop. I then discovered that I actually had to flash the ICS bootloader berfore installing the new rom.

You can't install official ROM with CWM. You need Acer recovery! This issue has been answered several times. Use search button!!!
Hello!
I was about to unroot and get back to stock with my A500 so I flashed a stock ROM via CWM to get a ota-update. Before i had a custom ICS ROM installed and now I installed a HC stock ROM. The problem is that i forgot to go through the wipe menu in CWM before the flash and now when I start up my tablet I first see the ACER logo as usual, then a android text-logo which the tablet is stuck at. I've waited 20 minutes and is still shows the same thing. The logo has an animation which i still can see. I've tried to restart the tablet and get into CWM again without succes.
What should I do?

I believe you have to have the HC bootloader. Now you have HC with ICS bootloader.
Please help me i am in boot menu of my Acer A500 and i don't know what can i do my Acer whene i push power bouton i am blocked in this meni :
Skrilax_CZ's bootloader V8
Booting primary kernel image
please help me to complet installing JB rom
Same issue here...Just tried flashing the new kernal in Goo Manager as well as a new ICS build within TWRP, and I'm hung at the same screen.
Time to do some homework. Any help is appreciated.
OK, got this working. Basically, it all boiled down to a bootloader issue. I was using an older bootloader with a JB ROM. Bad idea! I was able to get into recovery by doing a vol down+pwr to boot it up, then selected an older ROM from my SD card to get it back up and working.
I then poked around for updated bootloaders, and snagged v8 ICS bootloader.
I applied that guy, wiped the device, installed CM10, gapps for ICS and everything worked.
Hi,
Guys I need your help on this one.
I sold my A500 almost a year ago to a friend of mine. At that time I flashed it with a HC ROM and Recovery 1.3.4.
Last week the new owner of the tabled asked me for help updating the ROM to JB. Since now I use a Samsung Galaxy I completely forgot on the correct procedures to update the Acer A500. I simply downloaded a 4.2.2 Rom and tried to flash it on recovery mode.
After that I'm stuck with an endless loop. The tabled boots, pass the Acer logo, shows the ROM logo screen and than boot again.
Since I can still acess the recovery screen (it still shows 1.3.4 recovery) I tried flashing other ROMs with no sucess. Every room that uses the Aurora installer freezes as soons as Aurora Installer message shows on the screen. So I wasn`t able to flash a new Rom or a new Recovery (since all the Roms and recovery that I have found uses the Autora installer).
I also tried to install an older room (Tried the Lightspeed 2.1 ROM) and although I was able to flash it and reboot from recovery, it stops on the boot screen after that (I waited for 4 hours).
Can you guys help me with this one? Also, do you guys know if I can install a new Recovery using Odin?
Thanks
Anyone?
Maybe you should try flashing stock rom. Download 》rename it to update.zip》install from sd card or use EUU roms.

Simply put, this is what happens when a rooting newbie discovers custom bootloaders and ROMs.
Current State:
A full stock ROM installed (no root) with the Skrillax V8 bootloader plopped on top of it. (which of course means the recovery-from-boot.p file still exists and that I don't have CWM.) The tablet will show the Acer logo then the Android logo and will give the appearance of booting. Then the icon flashes. It does this intermittently and forever.
What I want:
CM 10+ running with Skrillax and TWRP stably. I'd go with Flexreaper for next choice. Maybe I'll try to compile a KitKat version for it someday. Who knows.
How I managed to get my tablet in this crappy state:
Rooted tab a long while ago with a probably far outdated method.
Looked all over the internet later on how to unlock the bootloader and settled on the manual method in this excellent thread.
I flashed V8 and TWRP without a hitch using nvflash.
I wiped and installed Flexreaper.
I liked it but wanted a higher prize. I make a nandroid backup of it onto the external_sd and wiped and installed CM 10.1 from this thread.
This is where everything started going sour. It told me the install was invalid halfway. Disappointed, I wiped again and tried to restore my nandroid backup. It seemed to restore properly, but then Skrillax hung forever loading the kernel.
I wiped again and installed Flexreaper fresh. This time it booted. I downloaded the newest unofficial version of CM they mention on their wiki.
Booted to recovery and installed CM 10. It ran fine and I was impressed with the new OS. Then I noticed the apparent lack of Gapps.
I flashed the Gapps Jellybean package and rebooted. Skrillax hung.
Wiped everything I could fine in the TWRP menu and installed Flexreaper. Got past the primary kernel loading but the android icon would work for a bit then flash, starting all over again.
At this point I flashed several other recoveries, hoping it was my recovery. No such luck. I tried all of them included in V8.
Then finally, I downloaded full stock ICS and flashed it. I rebooted and noticed the same Android flashing thing.
Finally, I flashed V8 again, being the newbie I was, and then suddenly remembered while trying to boot to recovery that the Full install probably rewrote the recovery-from-boot.p.
And here I am.
Tl;dr version:
Went click-happy with ROMs, wiping, and recovery flashing until I was left with a stock OS that wouldn't boot with a Skrillax bootloader but no recovery.
The good news is, I still have cpuid+sbk, it still boots to APX (no idea how I didn't screw that up too.), and I have a nandroid backup on my external_sd which is probably untouched, since I was careful to not wipe it in TWRP.
Please help me fix this. I don't want an excuse to waste money on a flashy new Nexus or Asus Transformer tablet, I already have too many for my wallet's comfort.
I quess you renamed stock rom to update.zip and than flashed it? If you havent do it, put it on sd card and pres power+vol down (if nuttin happens than vol up). That shld trigger flashing proces

I don't have access to a micro sd card reader if the file must be placed on the micro SD card. I already have flashed the stock rom supposedly via TWRP, so I shouldn't have to flash it again, I wouldn't think. If I do, I guess I'll have to get a reader.
Yes. Micro sd. Rename it. You have guodes gere on xda. Im hoping it will help you.

It didn't work. Still in same state as before.
I also have access to fastboot if that would help.

Babsector should still work - you would need t do a search for it
It seems to have worked properly, sort of. Flashing FLEXReaper results in an "Encryption failed." prompt at boot, which the button, of course, does not work. Wiping everything works except that the prompt notes "E:format_volume: make_extf4fs failed on /dev/block/mmcblk0p4" Trying to reflash V8 with TWRP with the V8.bat file fails at format. More help?
My tablet is still displaying "Encryption failed", the button still doesn't work, and I still love my a500. Help?
Anyone?
I guess I'm screwed, then.
In the end, I think my data partition failed. Formatting or wiping data fails and when installing FlexReaper, it reports /data size as -1. Unless anyone knows how to fix flash memory, I think I'm stuck.
