Hello and thanks in advance for any help!
I am A NOOB, at the whole android software/rooting/unbricking.
So I am having issues while unbricking my currently bricked tablet, the way it goes is it will get a quarter way through recovery mode and then the entire process stops and I get the caution sign inside the triangle.
I have the update.zip file on my sd card, but unable to mount the image and boot files on the internal SD, so they are also on my sd card.
Startup reads Secure Boot: Image LNX checksum Fail!
So what I'm asking for is a way out, to even go back to stock would be fine with me, with no attempts to go on with systems I am unfamiliar with.
Any help is appreciated so much, currently deployed for the Air Force. So computer access is limited, and all I have is my bricked tablet. So if I am slow, I appologize.
How did you brick it. Do you have a external SD card?
Originally tried to root it.
Silly me, I really didn't know what I was doing, and long story short, Im bricked.
Yes I do have an external SD Card.
There is a thread in the development section about fixing checksum errors. Read it.

Any help would be appreciated. I am fairly new to modding android phones, so I wanted to make sure I get pointed in the right direction before I cause more damage.
I was messing around (like an idiot) and somehow screwed up the
/system/framework/framework-res.apk
My phone is now stuck in a continuous boot loop, but I can get into the bootloader. The phone is rooted and it is S=off.
Again, any assistance is greatly appreciated.
If you made a backup, or can get a copy of the ROM and copy it to your SD card, you may be able to use recovery to restore it.
If recovery is also messed up - good luck.
I have been working on this for the past few days and for the life of me cannot figure out the problem. I'll start by just laying out a sequence of events.
Bought A500 about a month ago. OTA'd to HC 3.1 4.010.13_com_gen2
Decided not to wait for OTA 3.2 and rooted with iconiabreak.
Did not do a backup (like an idiot, i know)
Flashed Taboonay 2.0 with Thor's 2.1 kernal.
Saw awesome post to get rid of cell standby by deleting phone.apk and telephony.apk....do i did that.
Realize i am an idiot and then run a Nandroid backup.
Was happy for a few weeks when i see that Vache had updated taboonay to 2.1b and decided i wanted to do that.
Downloaded the files and started to flash with CWM. Factory, cache, dalvik wipe. Run Taboonay zip.
Get stuck in bootloop at Taboonay boot screen. $#!t......
Think "it's ok, ill just do an update.zip and go back to 3.1"
Try almost all the files on Vache's full package and update thread.
I put each one on an ext sd card and throw it into recovery boot. The Android guy with gears shows up and it looks like it is going to work.
The progress bar gets about 90-95% of the way when everything just stops. Gears animation, progress, everything.
It then reboots and gets stuck in a bootloop at the android screen. Load a different update.zip and same thing happens each time.
I try to just do a normal recovery boot, but CWM isnt there anymore and i get the ! android.
Normal reboot gives me a bootloop.
So i am stuck and asking if it is the phone and telephony apks that caused everything? if that were the case, how would i be able to load them back up since im totally locked out. I havent tried adb since im out of town for a few days. Thanks for any help that anyone can lend me. Ill try to answer any questions for any information that might be needed.
bumping for great justice~
I've tried decrypting update.zip files and vice versa.
still no luck..
try the fall back to 3.0.1
Check under development section for iconia a500. You'll see a thread for going from 3.2 to 3.0.1.
As i readd about this rom, it seems it's used in difficult cases (it removes the locks created by 3.2 stock), so it could be worth giving it a try.

Thanks for the reply.
I don't think that will be a viable option for me since i'm not able to get my UID. i've plugged my tablet into the computer and gotten the "hardware found" bubble. It prompts me to look for drivers (which i havent be able to find) and, i assume because it's in a bootloop, wont show up on the computer.
Does anyone know why the update.zip files would fail at 90%? I think that's really the thing that boggles my mind and is most frustrating.
Did you at all have your A500 connected to your computer prior to this happening? If so then you can get the UID from by way of the Windows registry. Then you should contact SC2K and get him your UID he should be able to help you get your A500 back from the dead.

Unfortunately, no I never plugged my A500 into my computer.
quick update:
I was able to use a different computer and found something interesting.
While trying to transfer or open a decrypted update.zip file, i get an error message saying, "Please insert the last disk of the Multi-Volume set and click OK to continue". Clicking OK just brings it back and i am forced to click cancel.
Anyone have any idea what that would mean??? It doesnt happen when I open or transfer the non-decrypted file. Only the decrypted file using Thor's Acer Update Decrypter application on HC 3.1 and 3.2 files.
While loading the decrypted update.zip on the A500, it almost instantly shows the ! android guy, while the non-decrypted files go 90-95% and then reboot into bootloop.
Any help would be greatly appreciated!
first off if you can get into recovery to flash anything.You are not bricked.
Take your SD card put in a android phone format it.
Put the card in your computer.copy a full update.zip file from dev section.likes on a post by Thor.put card.back in tab and flash.
If it stall fails repeat with a different SD card.seems smaller ones do best.
Good luck.

Thanks for your reply, first off.
I'm sorry I didn't make it clear that I had done all of those things during the events of the first post EXCEPT try a different sd card.
So I went out today and bought a PNY 2GB sd card as opposed to the SanDisk 4GB i was using. I formatted it in my Atrix 4G and threw a full update.zip file in there. The first file I tried (from Vache's http://forum.xda-developers.com/showthread.php?t=1113878 thread) was Acer_A500_4.010.38_COM_GEN1 (HC 3.1). Since I was able to open the .zip without decrypting it I loaded it only the sd card. It did the same thing as before (loaded to about 90% then freeze, reboot) except this time I got a "Boot verification failed..." message in bright red letters up at the top left of the Acer screen. Since it didn't work, I loaded Acer_A500_7.006.03_COM_GEN2 (HC 3.2) onto the sd card. Again, since I was able to open the .zip file, I assumed that there was no need to decrypt it. Loaded the sd card and put the tablet into default recovery (not CWM recovery which I no longer have). The same problem keeps happening: it loads to 90%, freezes then reboots. This time, however, it went into a bootloop at the "android" screen.
I've tried decrypted versions of those files, but I always get an error message while trying to open them and when trying to flash them in default recovery, it almost instantly goes to the ! android guy since I'm assuming those files are already decrypted and decrypting them again is bad.
Hopefully if I try enough files, I'll find the one that works...
Until then, if anyone has any ideas as to what I might be doing wrong or should be doing differently, please let me know!
Thanks.
there is a thread that has instructions on going from the OTA 3.2 to downgrade. To 3.1.look for that tthread and windows software. On that thread it talks about that error your getting.
Since I have not had this issue .can't say for sure if it will help.
Good luck sorry I can not do more to hhelp
Just a dingy blonde here.

Thanks for your suggestion.
I was able to find my UID from an old CWM backup file and tried this method. I attempted it last night with no success. I was actually in the middle of making a reply saying how heartbroken I was and that I was basically giving up. I decided to try it one more time and made a slight adjustment from my method last night. In the UID file, I had my UID in there as 0x0blahblahblah and kept getting the incorrect UID error in the program. When I tried taking out the first 0x in the program, it gave me an incorrect format error. That is where I was messing up.
Instead of 0x0, all i needed was 0blahblahblah in the UID file.
Attempted the upgrade utility again, and viola! It worked like a champ.
So thanks again to all that helped out and offered suggestions and to all the Devs for their outstanding work. I've definitely learned a lot from this experience.
Hi guys, I apologize for the very specific question, but I really need help and will try to be as informative as possible.
A few days ago, my tablet froze, and unlike the other times it's frozen, didn't restart automatically. When I rebooted it, it hung on the "ACER" boot screen. After hard resetting, and factory resetting after nothing else worked, I did some research, and found that I may have a burnt out NAND drive. ****.
Whenever I try to run NVFlash to read or write, I get the 0x8 error, "Fatal read/write error", which seems to back up the idea that the internal storage is shot. (And yes, I have the right SBK and everything, --sync works fine.) --- (Also, I spent two days learning an easy way to retrieve the CPUID from APX mode if anyone needs help with that.)
Blackthund3rs A500 APX Flash tool hangs on the "Uploading" part of the process. I tried both Thor's recovery and TWRP's recovery with the same results.
According to this topic it is possible to run the system from a micro sd card, though it will be slower than internal storage unless you have a class 8 or class 10 micro sd card. So I was wondering if there's any way to install a system, including rom, recovery, and bootloader, to a sd card to run on the A500? And if so, if it's ever been done before.
I really need this to work because I don't have the money for another tablet, and I don't want to spend the money for a whole new motherboard. If you can help me out, I'll buy you a drink.
Thanks,
-Tibyon

It was running OTA ICS. It was rooted. Acer's ICS update was never stable,
I would really like some input here guys.
Maybe just a bad sector in memory card. I read somewhere (old guy can't remember where) some one had the same problem. They did a scan an repaired (locked out that sector) then the tablet worked because it did not use that area of memory. This is how hard drive disks fix memory errors.
Google search of repair memory card might get you tools.
Sorry can't be more help.
I took a bunch of backups before hand, but I put them on my laptop, so they're not on my phone. I've tried connecting my phone to my laptop, but I can't access the filesystem of my phone through my laptop. I can, however, boot my phone into TWRP recovery through a .bat file on my computer. The only thing I've managed to be able to do from there is wipe the phone and flash stuff. The only thing I've got on my phone that's useful is two .zips, the PA 4.4 zip and the Gapps that follow. As far as I can tell, the only thing I need to do to get my phone working again is to get my backup files back onto my phone somehow, but I cannot seem to get that working.
I've tried the ADB push command, but it can't detect my phone, so that's not working.
I'm wondering why the .bat works, as I can tell by the log that it is sending files to my phone! Somehow it manages to do it, but I cannot send my own files. Why is that? Also, looking at the log from previous times, It sent the files with speeds of several MB/s, but now it's only sending them at like 100-200KB/s. Is my SD card damaged?
I've read through a bunch of guides, and several of them states that the stuck boot animation is caused by the cache, so I tried wiping that. However, for some reason, it's begun to say "Error: Operation failed" when trying to wipe it again.
Help please
## Fixed it.
Could you post the .bat file that you used? Sorry if its a bit off topic but you are the only person that I can find with a similar problem as me and I have my phone stuck in the boot animation. I can't get my phone into recovery mode and was hoping that your .bat file could help me. I have a back up in twrp that I could use.
Hello all.
I suspect that my Verizon S5 has a bad eMMC. I read that there is a bug in ODIN that allows you to flash a ROM to SD instead (TFlash mode), but I'm not really sure how to do this. A paper was written on this, but I am not at the level to truly understand how this works.
https://www.sstic.org/media/SSTIC20...ticle-attacking_samsung_secure_boot-basse.pdf
Is there anything I can do with this to revive my S5?
All help appreciated.
