Hey guys,
So i am trying to put into recovery mode off reboot because i had a rom install that didnt run properly. When i do the volume down method, it goes to the HBoot screen, and immediately starts calculating some stuff on the screen, it doesnt let me scroll up and down to any other options. Am i missing something?
calculating stuff? when you get into hboot you should be able to push the volup or voldown to scroll to recovery and then press power to select. otherwise pull your batt. and put it back in then just plug the phone into a wall outlet or usb. if your on CM it will boot CM up automatically. (sort of a glitch, but in your case it might save you instead haha)
the calculating is just the bootloader looking for an update.zip. a few seconds after it finishes you should be able scroll down to recovery.
Problem Solved
When i let the update.zip load. It said to let it update, or press power to reboot.
It kept fast booting.. I think thats what the problem was.
Solved the problem by starting without the SD card mounted. Then once it loaded I was able to arrow up and down. Popped SD back in and was able to properly recover.
Thanks
Hello,
I have a pb with my acer Iconia.
The tablet is blocked on the screen "Android" ...
I tried the button "reset" but nothing better ...
Is there a way to make a hard reset (factory reset) with a combination of buttons ?
Thanks a lot !
PS : My Acer Iconia Tab is "rooted".
Try holding the power key down till the unit shuts off, then let go and hold it down again till it restarts. Good luck.
I've found holding the volume button closest to the corner and power button at the same time forces a restart. Of course, I haven't tried just holding down the power button alone when it's frozen, so the volume button may not be necessary.
I am having the same problem with mine. My widgets started acting weird and disappearing. I thought a reboot might help but now it gets stuck on the Android load screen. I have tried hard reset and holding volume up during reboot. The latter takes to a recovery boot but seems to search on the SD card which doesn't really help. Acer tech support is absolutely worthless and it is too late to return to best buy so now I have to ship it to acer for service. Sucks.
Try this. Plug in a usb keyboard and power on while holding volume down. Keep holding both buttons until you see clearing cache in the upper left and you can then enter a menu by hitting HOME on the keyboard. There is an option to do a factory reset. You will lose all user data by doing this factory reset of cache and data but it may just get your tablet back. There are some other posts on this in dev if you search. Good luck.
maybe.you,both have a bad app that is causing this
try comparing installed apps .might.find what is the.cause

I did this and it will boot now but during setup the setup wizard FCs and starts over. I checked the Dev sections and I didn't see anything on factory resets? I'm running out of options.
I would try a couple times to boot since cache has been cleared, sometimes it will fix itself after the programs have a chance to JIT compile...it is typical in Android to see some FCs after the cache is cleared. If after a couple boots things aren't working their way out then you may have to flash a system image for your build, however this shouldn't be necessary unless you rooted and changed some stuff like uninstalled system apks etc.
What I did before the factory reset was replace the whole /system/app folder ( that I deleted some bloat ) with one that was complete like stock. I got a bunch of FCs, followed by a black screen. So I followed the steps you provided because the symptoms fit.
I've also done multiple restarts and the setup wiizard is still FCing.
this is my build Acer_A500_1.104.02_COM_GEN1 doubt this will help me.

If I were you (note the disclaimer), I would find and flash the complete system.img file for your build (see the [Dev] System Images thread). Once you have the proper system.img for your build in hand, then you can write the system partition in it's entirety. You can find examples of this in the same dev thread.
Cliff's notes:
Use adb to connect via usb and place the the system.img into /mnt/sdcard (adb push command), or you can do this another way if you have access to your storage via USB. It will take some time to copy, several minutes at least.
You will need root to do the rest, but obviously you already do if you overlaid system/apps. Using the adb shell as su, mount the partition as writable and use the dd command within the adb shell to restore the system partition. It will take several minutes to write, so don't panic.
Here is an example of the dd command if your .img is called system.img in /mnt/sdcard:
>adb shell
# su
# dd if=/sdcard/system.img of=/dev/block/mmcblk0p3
# reboot
do i need to try adb i cant get my android market to load it force closes every time, i wished i could just load an factory image from older version and then let it grab the updates and start from fresh, i am rooted which may have been a mistake. i can hook an usb keyboard up hold home key get into recovery but if i put an rom.zip on sd card it doesn't see it.....what am i doing wrong.
Hi There,
I have also the problem that when I booting my tablet it stucks on the Android logo. I have tried to hook up an usb keyboard but he can´t find him. I get the Androidman with a note of exclamation.
Can someone tell me where I did go wrong? If I try it I see the cache messages etc. in het left corner.
My tablet is not rooted.
if you want to do hard reset first of all make sure you have an appropriate upate.zip on you external sd-card preferably use a stock rom.
after you do volume+ (up) and power once it vibrates keep your finger on volume + and toggle the screen switch few times. then let it go it will update.
Thank you for your answer.
I have searched for a update.zip and I have download and ecrypt this file: Acer_A500_1.104.02_1.141.07_COM_GEN1_1305615165779_f0150ee4
If I put this file on my SDcard I still get the androidman with the ! in it.

That file is an incremental update and is ONLY for updating FROM 1.104.02 TO 1.141.07.
If your version doesn't match exactly, the update will fail. You'd be better off grabbing one of the 3.1 OTA updates in the thread in the dev section, as these are full ROMs.
I have tried the HC 3.1 ROM. This ROM was 487 mb but I still get the Androidman with the ! in it.
I have tried the file: Acer_A500_4.010.38_COM_GEN1.
The other files were 47mb
Reformat your SD card, or try a different one.
Locked at the android screen

I have a similar problem. Tried this and was able to do factory reset. However, after that, the same.The tablet is still stuck on the screen "Android" ...
During factory reset, I noticed the following messages on the screen:
E:/dev/block/mmcb1k1 does not exist
E:/dev/block/mmcb1k1 does not exist

E:/dev/block/mmcb1k1 does not exist
E:failed to mount/sdcard

What does this mean? Is there a way to fix it?
Somebody, please help! Thank you!

Try step 2
Also, advice for a hard reset.
Hi folks,
Have tried following the advice below, downloaded: Acer_A500_4.010.38_COM_GEN1.
Added it to my SD card and then tried to boot whilst holding volume down.
It seems temperamental. Sometimes the Android with the ! appears and there's no progress bar. Sometimes the Android with the ! appears and there is a progress bar, but it never makes it past 25%.
I've tried formatting my SD card and redoing it but no joy.
Any suggestions?
Cheers.
Hi all,
I tried rooting my Nook today following this procedure using unooter
http://wiki.cyanogenmod.com/wiki/Barnes_&_Noble_Nook_Color:_Full_Update_Guide
I got up to Gaining Root Access. After unplugging from the pc the nook won't power up.
After than the nook will not turn on. Hold the power button down, or all the buttons, nothing.
I plug the charger in and the green 'n' light on the usb cable is always green. Also when plugged into my PC and Mac.
If I plug into a Mac, it recognises it as an additional Ethernet device.
I tried restoring based on this thread:
http://forum.xda-developers.com/showthread.php?t=914690
But no luck. Nook won't boot or startup.
Any thoughts??
In either of those processes, did you create a bootable ClockworkMod Recovery SD card? If not, grab this image, extract it, and write it to your SD card:
1GB CWM Card
It doesn't matter how big your card is, the 1GB image will work for our purposes. After you write the image, put these two files on the card (do not unzip):
update-nc-stock-1.2-keepcwm-signed.zip
repartition-boot-with-stock.zip
Hopefully you'll only need to use the first one. Put the card in the NC and attempt to power on--hopefully it will boot to the recovery menu on the card. Volume buttons are up/down, home is select, power is back.
First, in mounts and storage format system and data. When done, go back to the main menu (power button). This step may not be necessary, but won't hurt.
Now, install zip from sdcard > choose zip from sdcard, and try update-nc-stock-1.2-keepcwm-signed.zip.
When it's done installing, hold the power button until the NC shuts off, remove the card, and power back on. If this works, the first boot will take a few minutes.
If it doesn't work, put the card back, boot to recovery again, install zip from sdcard > choose zip from sdcard, and try the repartition boot zip.
Let us know how it goes.
I wanted to revert my nook and start over because of my sd not working. Anyway, I was following "Restore Nook Color back to stock EASILY!" how to guide and I forgot to add the zip file to the Bootable Clockwork SD image. The guide said "add the zip file to the computer as well". For some reason I didn't interpret that as saying put in on the sd card.
I am now stuck where I cannot turn the nook off. It just has the following choices:
repoot
apply update
wipe data
wipe cache
etc...
How do I shut down the nook?
Also, the guide mentions to add NC 1.0.1 zip file to the card. Do I do that after I reboot the clockwork image. Any help would be appreciated.
It sounds like you're at the stock recovery screen. If you simply hold down the power button (could be at least 20 seconds) it should turn off.

K, thanks. It worked.
Due to my own actions (idiot) I deleted the recovery partition to try to regain 9gb it took from me. I would like to reformat and start again but I cannot. I have tried the following dell advice:
these are the steps to reset your tablet:
1. If your device is not turned off already, hold the power button for 10s to power it down.
2. Once it's powered down, press the power button to turn it on.
3. When the Dell logo appears (you may have to do it as soon as the screen turns on instead of wait for the logo to appear), hold the power button again to turn it off.
4. Do this process 3-4 times (they said 4, but it was only 3 for me) until you see something at the bottom saying that it's starting automatic system repair.
5. From there, you should see a menu. Choose "Troubleshoot", and the next menu should ask if you want to reset your PC along with some other options.
6. Choose reset PC, and when you get to the two options that ask "just delete files" or "fully reset PC", choose the second option. From there you should be able to follow the instructions to setup your device.
When I get to restore it asks for system files? I have tried the Dell recovery but that fails as well.
I have made a boot disk on my USB via an OTG cable which is recognised by the tablet, but it refuses to boot from this even after setting the bias to 1st boot from the USB.
Can anyone advise me of how to solve this problem and reformat and start again.
