Acer Iconia A500 stuck in boot loop or bricked?

Ok, I looked in some of the threads already posted, but didn't really see the problem that I am having.
My A500 gets stuck in boot loop. I can access the recovery and wipe data, flash etc... however, none of that is working. After I have wiped EVERYTHING and reflashed the Thor ROM 14.2 I get stuck in boot loop again with the little blue android with the spinning gears... That's it. I'm spent, I have no idea what I should do next. I only paid $260 for this bad boy, so I'm not sending it to ACER to charge me money to fix it... Any ideas?

Have you tried to format your sd card and place a fresh download of the rom you wish to flash on the sd and tried again.. It sounds like there is something corrupt.
This would my first thing to try from what i understand about your Question . If you try the above and still have issues. post back all the details that caused you to end up in this situation. from rom version you were on at first and recovery your using as well as details on how you flashed.
Good Luck.

I'll try that, but skeptical about it. Since I last posted, I have tried a nandroid restore, flashing a different rom, a couple more complete data wipe/factory data resets, no luck on that. I am formatting the SD card now, in hopes I can get a good clean flash?
Edit: I just realized all the wipedata/factory rests I've been doing haven't worked as they never complete. They say 'error formatting...' and before I can read what all it says it cannot format, it disappears. I guess at first I just thought it was wiping really fast...
edit: formatting the sd card, did not work. im still stuck in bootloop.
Edit: I think I found my solution here: http://forum.xda-developers.com/showthread.php?p=23246074#post23246074
so far it seems to be working...

So that link got you up and running? I'm always afraid of the boot loop and like to prepare for the worst

Re
Do you get an error message when you try to wipe data factory reset? If you do then your data partition is corrupt, happened to me yesterday. the way you fix this is go into recovery>backup/restore> toggle backup and restore of internal storage (/data/media) so it says enabled>mounts and storage>format data. Then you should be good to go. This REALLY formats the data partition so EVERYTHING will be deleted on it.

first,sorry for my bad english. I've been able to light up my acer a500 but I got stuck in airplane mode on email section.any one can help me?

it fixed mine

Restoring CWM backup leads to splash loop

I'm using: NexusHD2-ICS-4.0.4-CM9-HWA V2.4
Something went wrong on my phone so I decided to restore a backup. I had one from 2 weeks ago. After the restore completed, I rebooted my phone. It was stuck on the ROM splash screen and never got past that. I left it running for 20 minutes. I tried clearing /cache and dalvik-cache, with no luck. If I format /data then it works, but then of course all my data is gone.
Luckily I had a previous backup which did work.
I'm nervous about nandroid backup/restore. Can I trust it? It only happened for this particular backup, but why would it happen at all? There were no MD5 sum errors at all.
Any advice would be useful.

I've had an issue only once with CWM backup where my data from the ROM was lost but the ROM itself flashed fine. I suspect though that I actually had to reboot a few times more before giving up so quickly, because somehow the wallpaper was still kept and I've found on occasion that my data from a ROM restore/update slowly comes back after a few reboots. Anyway, as for your issue, did you change partition sizes between the time you made a backup and when you tried to restore it? I'm using NexusHD2 and I know that the required partition sizes have changed quite a lot between the ROMs.

I did not change the partition size at all. The backup before this one worked fine, so it can't be that. I also just did a new backup of today, and restored it. It worked at the first boot and didn't take extra time. I then tried restoring the broken backup again but ONLY data, and again I got a splash screen loop. I doubt multiple reboots will help, but I did try that.
I have an urge to mount the data backup and slowly take out folders until I find out the cause. If not for anything else, just out of my own curiosity.

I am facing exactly the same problems...
In same cases i got bootloops when restoring a Backup, in other cases i can boot after restoring but then my data is gone and i am asked to configurate my phone again with the wizard...
I never tried to boot several times if the data comes after some tries...
Btw I also didn't change the partitions...is it possible that it has something 2 do with link2sd?

In that case (@OP) I'm guessing its just a broken backup. This is why I always use Titanium as well. It takes up less space and you can restore it on almost any ROM.

Are you using an A2SD script? or do you have an ext partition?
You may have resized it, you can also try formatting it.

are you coming from another rom, did you wipe data? redownload and try again? reflash your previous rom? restore a nandroid backup?

I wiped data, and I don't have a previous ROM or nandroid to go back to, because I (stupidly) wiped EVERYTHING last night, and I've been working on fixing it since then .... I'm currently booted to recovery though, and I may just push a new ROM to it and try again
says my SD card is read only? trying to remount it as rw

I ended up having to reflash all the stock images...

could be worse.
keep a copy of your latest running rom/kernel/gapps in your storage, for just in case. thats my normal procedure, if you dont want to keep a nandroid backup in your storage, because of its size. but a nandroid backup would be ideal

Having the same issue. Tried installing new Carbon nightly (with factory reset) and didn't boot past Google logo. After that I restored my nandroid, which lasted for about a day or two. Today I started getting force closes and phone won't boot. Now I'm backing up everything (ADB rules ) and will try stock image.

Dont feel bad. When twrp updated I didn't notice wipe internal as I usually wipe all but USB in bottom but it was too late. I had swiped my finger and lost everything. Worse? My computer crashed. So RMA backordered so I bought new s2 for backup. I have to fix before sending back. But its not broken. All asurion does is push files and make sure it boots. They wipe everything. So I did most of the job for them lol. I feel stupid as I've never had a problem in four years. Bam I got too far comfy and forgot the twrp updated and had no idea what was added. I will just find a computer and fix or they will get a wiped device with twrp lol not that I think they will do anything as I've heard far worse but I did it so I'll pay if they mention.

cwm recover not recognizing restore files

I recently rooted my phone and tried a few different roms. I'm currently on cyanogen mod 10.2. I used cwm to backup my original ROM. I copied the backup file to my computer and uploaded it to my dropbox. I formatted my SD card since it had a lot of junk on it. I copies them back and now they aren't being recognized. This is my original stock ROM and since this is my first time rooting I really want to keep a stock ROM on hand for easy access incase I mess something up and need my phone to work properly. Thanks for any help. Its also a Samsung s4 i337m from fido.

can you see the backup and it's just not letting you restore it or can you not see the backup at all?
i'll tell you to keep researching and troubleshooting but if all else fails, odin back to stock, reroot, install cwm and make a new stock backup again.

Its not appearing in cwm at all unless i have a restore that was on it post format and not copied off the computer. Like if I make a backup of my current ROM the stock one will appear and just hang in checking md5. If there are no backups other than the original stock one it isn't being recognized. Also it worked before I formatteebthe SD card.

when you formatted the card and then replaced the cwm backup, where did you place the backup?
for example: 0/clockworkmod/backup, /clockworkmod/backup, etc.
if you make a backup now, where does it save the new one?
i'm just running through the bases here.

Sorry I don't know the exact locatiotion but I just dragged and dropped the "Clockworkmod" That cwm created when I made my first restore to my PC. Formatted the SD card and just dragged and dropped it back to the SD card. The new restore saves in the same folder also.

i'm assuming they're both in something like sdcard1, extSdCard or external_sd /clockworkmod/backup.
if so, and you didnt change cwm versions (i.e. from 6.0.3.6 to 6.0.4.4), then something may have been corrupted when moving the backup folder back and forth.

Yes that seems about right. I didn't change anything on cwm, unless my ROMs did. If it is corrupted will it just hang indefinitely or is there a chance it can work? And is there any other way to do a restore?

i'm no recovery expert but if your backup is corrupt than i dont imagine there's a fix for it.
i accidentally deleted my stock backup a couple phones ago. in order to have a fully stock backup on the sd card again (in the event i needed/wanted to restore to the original factory setup), i had to odin back to the stock firmware and start over.

Do you know any good guides on how to do that?

Try to re-downloading from drop box. Could have gotten corrupted during the download process.

Download it straight from dropbox to the SD card through the phone?

true story.
report back. cheers

Nope, no luck. It just hangs at checking MD5 Sums. I tried the backup i made for foxhound 2.0 and it did the same thing.
edit: It worked it was just hanging for a good 15 minutes though.

Can you have cwm not check for the md5? It's been awhile since I've used cwm. I use twrp.
Edit, doesn't look like you can. I just flashed cwm to see. Was the foxhound nandroid one you just made and it still doesn't restore?

yeah, thats what i was gonna ask: if you've made one just now and tried restoring it.

Ok thanks for the help but the problem resolved itself after letting ti hang until it did something. It worked after about 15 minutes.
edit: I just rooted the phone a few days ago and I'm all new to this, so i figured after it not doing anything for 5 mins with the dead android on the screen was bad. Thanks for the help.

Good, yea a restore and reboot can take longer than you think. And waiting seems like forever when you're expecting it to boot. You'll get used to it.

[Q] Nandroid restore help

Hello,
Need some help with a Nandroid restore. When I did the backup everything went fine, and now when I am trying to restore it, when it gets to /data it is taking forever.
I am using philz touch CWM recovery. Samsung Galaxy S5.
I started it yesterday and it is still going, it says 800/5575 mb, so it has a lot more to go... is this normal? is it really going to take a week to do a restore?
Darth said:
Hi,
Since you're stuck now anyway, I'd restart the phone in recovery, wipe system, data and cache and try restoring again. But it may just be corrupt. If you have another nandroid, try to restore it.
Other options are use another device with a micro SD card and put a rom, and gapps if needed on it and install the rom on your device.
Last option is to Odin flash stock firmware again.
If you want other ideas or need further help, please ask in this dedicated help thread for your device,

Thanks for the help! Do you know if wiping the system will get rid of the clockworkmod folder? that is where the nandroid backup is saved...
I may just flash a new rom again, with titanium I should be able to recover everything.
Copying to the other thread too. Thanks!

Any ideas? should I stop it where it is at and flash a new rom? I wanted to after there was a stock 5.0 version out, but I could do it early.
I did take the backup and put in on my computer, and then put it on my phone again. Would that affect it? the SD card wont mount on my phone, so I only have the internal to work with.

Ok, so I decided to stop the restore and I am trying to now load a stock rom. I am running into a problem though, how do I transfer a file to my device? I have nothing to boot into, and the SD card does not work. Can I flash it with odin?

Solved?

I think I have "fixed" it. Finaly was able to sideload a rom. I am waiting for the stock rooted one to download still, but if it does and I can load in all my titanium backup stuff, all should be good. :fingers-crossed:
