Greetings and salutation;
I've been fiddling around with my new tablet, learning about flashing ROMS and such, now I`m trying to get back to the original stock. I think I deleted it, or the recovery image from the device because I keep getting a Cyanogen Mod load screen.
Anyway...
I've search the forums and seems like most of the information either dated with broken links, unclear, or assumes most viewers understand the vernacular/terminology.
Basically, I need to find the stock ROM for the Acer Iconia Tab A700, in English. I'm fairly confident with flashing it as I have that figured out. I just need to get my hands on a copy of something that will install.
I have an image right now, but I keep getting the following error bounced back to me;
"assert failed: getprop("ro.product.name")=="a700_pa_cus1"
"Error in /cache/acer_ug/update.zip"
If I can figure that out, then maybe I'm good to go.
Anyone feel like helping me out?
Thanks.
I've been having the same issue, I was following a guide on how to root this device when something went wrong (a file was out of date or something). Anywho, the devices now just loops at the Iconia animation on boot & I'm trying to find the best way to revert back to the stock rom, or something at all at this point. I'm currently getting the same error as you, I'm hoping someone more knowledgeable can help out or something. I'll continue my search tomorrow when I get back from work.
I see that this post was from about a week or so ago, have you found a solution yourself or are you still waiting?
Anything at all would be greatly appreciated!
Thanks a ton!
Hey there, not sure if you're still looking but I found how to restore stock!
Check out the following link, if you follow the steps exactly you're tab will have the stock rom.
http://forum.xda-developers.com/showthread.php?t=1812635
Just a note, the first time you restart is after flashing it might freeze on the iconia boot logo after it's animation. Just restart it with either the power button trick or the pin hole at the bottom...or side, depending on how you're holding it I guess.
Hope this helped!

Started reading the forums a few days ago, already planning on getting a gtab for x-mas. So got one at Sears today and went home confident I would know what I am doing. Well I was wrong !!
First mistake: My assumption that this will be as easy as my SGS with clockworkmod. For one, there are apparently CWM versions floating around that are known to cause issues - hence that is the one I ended up with. It installed the CMW fine and went into recovery just like I am used to. Tried to apply the ZPAD 2.2 rom and as soon as I rebooted got the 'Magic Value Mismatch' error at the top of the screen.
Mistake two: trying to fix it by finding the correct CWM called .8 which seemed to make things worse. I got a screen now right after the power and Vol + key that shows alternating black and white strips.
I had this thing only for 3 hours and I already managed to get way past my expertise on fixing this.
What can I do to get the tab to load a recovery image so I can boot?
On the internal SD card there is the folder called 'recovery' with the command file that points to the update.zip on the external sd card. I imagine that is correct. However it did not matter what ZIP file I place on the SD card. For example I renamed all the exising rom's one by one to update.zip to see if one of them would take and no luck.
I am sure someone with more experience can point me to how to get back to normal. I would appreciate some help.
Try This
I had a similar issue with mine about 30 min after I got it. Use your external SD and but the vanilla tnt update.zip and the recovery folder on it. Edit the command file in the recovery folder to say sdcard2 instead of sdcard. This worked for me , Good luck
Thaks for the info.
I created the recovery folder with the command file this time on the external SD card (preped this on the PC) and made sure the vanilla update.zip was on the root of the SD card.
I got a new error about a kernal having a critical error, but I was so frustrated that I did not write it all down.
Then I tried another rom (gtab lite 2.2) and I get the Magic Value Mismatch error again.
It seems like it does not even attempt going into recovery now, because it does not matter if I press the VOL+ and PWR key together. It has the same effect as if I press PWR alone.
I really don't want to give up just yet. If anyone else has any suggestions I am willing to try, plus this experience might help others in a similar situation down the road to recover instead of having to return the device.
I saw a post about some PC based update, but I also seen comments that that could make things even worse. Any ideas?
In the mean time I followed the NVFlash instructions and there is some success and also some loss.
The success is that I no longer get the "magic value mismatch" error. The loss is that my tablet still does not boot and now I have a Nvidia boot screen which will most likely raise a flag with Sears when I return it for an exchange.
I don't want to give up yet, but I really could use some pointers on what else to try.
Here are the instructions I followed for the NVF...

All I get is the Nvidia logo. The tab has been on for more than 10 min and there is no change.

My nvflash won't help you, at this point. You want bekit's nvflash recovery -- http://forum.tegratab.com/viewtopic.php?f=6&t=8 I know you used mine because you have the Nvidia logo.
The difference between bekit's recovery and mine is that bekit's flashes EVERYTHING, at a low level. Mine isn't that extensive. You definitely want to try Bekit's flash before throwing in the towel.
As for SEARS, I wouldn't worry about it - they probably won't even notice. When I returned my first one, they didn't even open the box. Seriously.

The link you provided (I already went there before) had a link inside to download the necessary fiels but all it did is link to the main forum page. I never was able to find the correct files until this morning I believe. I found another post on these forums that had 'dropbox' links to several files that I downloaded.
So now I ended up with 1) the Tegra MSI installation file 2) the g tab image files and 3) the windows script files with the batch file. I will attempt these tonight and report back.
We are in the middle of moving - finally home owners again at last ;-). I have no internet connection at my new house yet however my SGS and tethering are my friend right now, so I can post and download at a lower rate.
Thaks for the help!!
I wonder what came of this! A feedback would be nice.
Thanks!
i would guess roebeet's suggestion worked, otherwise anosis would've been back on here.

No PM's to me, yet. I take that as a good sign?

I believe you deserved a big thank you instead!
Thank You!
I don't know about the other guy, but I borked the Tab tonight, and these instructions worked flawlessly. The links to the apps were stale, but the IRC channel pointed me in the right direction.
Now back to to the Tablet to find out what I need to put back on it.
Thanks again!
can you tell me where to find those links? I screwed mine up too.

Saved my bacon!
This thread was awesome! Pulled my ace out of the fire when i accidentally wiped out CWM when trying to format to install a new VeganTab. You guys rock!
Hooray!
Sorry to bump an old thread guys, but I just wanted to chime in and say this also worked for me. Someone should add this to the stickied threads...

Hi,
I am just wondering if you can provide a more detail instruction on how this can be fixed? I am a new android user, I am not very knowledgeable. If you can provide some more information, that would be greatly appreciated!
I beleive what you are looking for is in the link posted.

mismatch is good
I finally did the nuclear option to get my tablet back. I was in the dummies site when panicking as well, read mismatch was to be a welcome...
My Droid 1 is stuck in the boot cycle, it crashes on the little red eye and reboots and begins the process again. I have backed up my stock rom but each time I try to load it from boot loader I get a "signature verification failed" error. What can I do to fix this. Thanks in advance to all those who help..
What were you trying to do that made it crash?
I installed a battery icon mod that I found on this site. Stupid...I know. Any thoughts? I am researching how to unbrick a droid right now, am I on the right path?
I just thought I would give everyone a quick updated. After several terrifying hours I was able to recover my droid with the Unroot/Unbrick any phone method found at droidforums.
So now my question is, now that I’m back up I currently have android 2.0, build ESD20 on my phone, any idea how long it will take before Verizon brings me back up to 2.2.1? Or is there a better way to do this?
You could try searching around for a rom on this site, but you would have to root your phone. Look in here for a rom that suits your needs: http://forum.xda-developers.com/forumdisplay.php?f=671

Ok, I've done something stupid and I don't know what.
I've searched the forums for about 5 hours now, and can't find any help. If I've missed something, I apologize. I'm kind of frazzled.
I was trying to install an updated ROM from my internal SD via CWM recovery. There was an error, and now I'm stuck in recovery mode. I've tried clearing everything, but it won't boot to anything other than the CWM Recovery screen. I can't go into download mode to flash anything, or else I would just flashback to stock and start over. I even tried the whole taking your battery out and plugging the tab in to go to DL mode, but that does nothing.
We're dealing with a Galaxy Tab 2 7.0 P3113.
I'm about to cry.
Plz halp.
I might have it fixed now, but I don't want to get ahead of myself.
I finally managed to time my button mashing well enough that I'm in download mode. Will update soon.
If anyone cares.
I GOT IT
Ok, so I sill don't know what I did to end up in his mess, but through what I count as sheer luck I ended up in download mode, and was able to use ODIN to flash a stock rom.
I would delete this thread, but I want to leave it open in case anyone else runs into the same issues.
I had a similar issue when trying to update my rom, I found this to be particularly useful: http://forum.xda-developers.com/showthread.php?t=2302599

I did read that, but I was flashing a GB ROM, so I figured it didn't apply. I do appreciate the tip, though.
I decided today to read a few guides and watch some videos on how to root my HTC One M8 w/ Harman audio. So I successfully rooted it, and installed Carbon Rom. At first things went well, and to make a long story short, I would REALLY like to revert back to my original firmware. All bloatware included, I dont care. I really have no idea what I'm doing with any of this, and the internet keeps bringing me here to find solutions so I figured I would post my question. Currently I'm downloading an RUU with hopes that it will magically fix everything (file name: RUU_M8_WHL_K444_SENSE60_SPCS_MR_Sprint_WWE_Harman_3.30.654.2_R_Radio_1.08.20.0916_NV_SPCS_1.52_003_release_395175_signed_2 (1).exe)
If anyone could please just give me some sort of direction on reverting back to the normal firmware, I would be IMMENSELY appreciative.
Tried running RUU. Made it worse. Now it's stuck at the carbon boot splash. Cant even take out the battery. I have no idea what to do now, goodnight.
You might start by checking this thread: http://forum.xda-developers.com/showthread.php?t=2701376
There are instructions on how to get into recovery and download the stock firmware, based on the results returned from running certain fastboot commands.
Please keep in mind that I don't have the M8, nor have I tried the steps mentioned, so this is entirely at your own risk.
Good luck!
Ok, so there was a thread on here for this issue, but it has been dead for 5 years so I hope it's ok I open this new thread.
I have been given a Samsung Tab 2 GT-P5110 by a colleague of mine. At some point in time he managed to corrupt the firmware to get the black screen of death 'firmware has encountered a problem.......'. This will not have been from flashing ROMs or attempting to root the device (he's an elderly guy, who recently asked me for help resetting his Google passwords, so rooting is well beyond his expertise). I first thought this won't be an issue, I'll hook it up to Odin, flash a recovery, stick it in download mode and then flash a new ROM...... However this failed, Odin confirming the process was unsuccessful. I understand this may be because the corruption is seated deeper than just the level of flashing a new ROM and have read flashing a new kernel may go deep enough to make progress, however, I have only ever used Odin for flashing ROMs so this is all new to me.
I would be very appreciative if someone was able to point me in the right direction, I have found some kernels to download which I think would be compatible, but I'm a little foggy on the steps I should take. Alternatively, someone may know another route to go down, I am also not afraid to open this little guy up and do some DIY surgery if needs be, after all I didn't buy the thing so I have nothing to lose.
Any suggestions would be great and if you want some more info please feel free to ask.
Thanks in advance.

flash a custom recovery, and install this, https://builds.unlegacy-android.org/aosp-4.4/espresso/ua_espresso-4.4.4-20171105172717.zip
Thanks for the reply. I have attempted to flash a recovery, however every one I've tried fails and tells me 'NAND write failed'. I tried the TWRP recovery and philztouch. You don't have a link to a recovery you think might work? I'm pretty sure I've been using recoveries that should work, but you never know.
