[Q] OTA update keeps failing to download

My wife got me a brand new A500 off ebay a couple of months ago for a Christmas gift(for me it's only three days old). So far I love it but it will not take the OTA update that it keeps bugging me about. The download starts fine but then stalls out mid download. I looked here http://forum.xda-developers.com/showthread.php?t=1113878 but did not see my current version there. Can anyone point me in the direction of the OTA I need to download and flash with recovery? My build is Acer_a500_1.145.09_com_gen1 I'm running 3.0.1. It looks like it's trying to download 4.010.11.
Further info:
According to the log the file name is Acer_A500_1.145.09_4.010.11_com_gen1_1311243587838_bd1ab95c.zip
I can't find that file anywhere on the net.

The reason I would suspect is because someone replaced the stock recovery? Off eBay you say, was it brand new and never used? It sounds like it was used or someone tampered with it?
If that's not the case, then you can just install the update manually. Download the update you want and put it on your external SDCard and then enter recovery (using power and volume). The recovery will install the update for you.

It said it was brand new. My wife would not buy something like this used. The weird thing is it knows it has an update and it starts to download and get's up to half way downloaded and then it just stops. It shows that it still is pulling data but the downloaded file size doesn't increase anymore after it stalls.
Ive been looking into rooting it and since I'm on 3.0.1 it appears Gingerbreak is all I need. The next question is what rom should I get and how do I go about installing it? I've never rooted droid before and most instructions on XDA are written for the experienced level and not the new guy. I'd like to stay fairly stock but rooted.

There are reports of others having the same issue. They say that a soft reset often fixes it.
You can use my tool to flash in 3.2.1 which is rooted. http://forum.xda-developers.com/showthread.php?t=1307539&page=14

Just to make sure I'm getting it right: I go here http://forum.xda-developers.com/showthread.php?p=20680452 download that to my PC and follow the instructions contained within and I end up with a stock rooted 3.2.1? I don't need to download anything else right? A soft reset for this tab is pusing the little red button on the end by the USB port?

Yes, if you want to flash 3.2.1 stock with root read the instructions in the download. The download has everything in it.
The soft reset everyone talks about is using the paperclip in that little hole next to the USB port.

Sweet. You're a life saver. Thanks for translating it all to noob for me. Will I need to reinstall all of my apps and such afterwards?

Yes, the flashing tool makes it just like new, out of the box, but with root.

Here is the error I am getting.
sent from my nexus 4 using google mind control

The OTA installer checks every single file it intends to patch before anything happens.
If a single file that is checked has been changed by even one byte, not one patch operation will occur.
The message you are getting means you did something to change or remove that file compared to how it was in the stock ROM.
Note that the installer halts on the first error of this type; there could be zero or many more of these errors awaiting you.
In short, OTAs are not meant for patching random non-Stock ROMs.

I installed beats from play store. Gutted. Just backing up all my data and gonna factory reset and try again

Odp: Unable to install 4.2.2 upodate
Guys, guys, guys. You need STOCK recovery for official updates.
Sent from my BMW E34 using XDA App

I searched many threads when I rooted and unlocked my Nexus 7 3g, to avoid this "status 7" problem.
I chose Wug´s nexus toolkit, unlocked and rooted my device. After that, I installed, via toolkit, the TWRP recovery.
When I received the system update notification, my device asked me to reboot, then a screen of TWRP appeared to me. I just rebooted the system and now, without update, I don´t even get the message again.
I assume that the Wug´s toolkit flashed a grouper version of TWRP. What I have to do now ? I would like to do the things manually. Maybe flash a factory image from here with this method.
I´m very noob with this kind of thing, because I still have a old milestone 2 with a locked bootloader. The method to flash ROM in milestone 2 is quite different...
Anybody can help me ?

There is modified OTA floating somewhere that skips check, worked for me since it reported that GoogleCalendar.apk was different than it should be....

Folks,
You need to stare at the actual error message.
If the failed assert() is complaining about a file (e.g. see the OP's 2nd image attachment) then THAT FILE IS THE PROBLEM. It means that it was altered or removed by a root-privileged operator from the way it was in the stock ROM.
If the failed assert is complaining about a build number, then it is possible that using a different recovery will allow the OTA to succeed.
So you have a couple of choices:
A) Go and find the stock version of the file and put it back into your ROM (with the correct file ownership and permission modes) and repeat the OTA install. Seems like a dumb idea though, as the installer stops on the first error encountered - you will need to keep repeating this process until you have restored all changed files. Could be only one file, could be a few, could be many. Note also that this applies to the boot image, too. Got a custom kernel? You'll need to put the stock boot image back in place, too.
B) Back up your apps using TiB or Carbon. While you are at it, take a nandroid backup too. Install the Factory 4.2.2 ROM, reinstall your fave custom recovery, and root the factory ROM. Boot it up, enter your Google creds, restore your apps & data (Carbon or TiB). Yep, you are gonna have to redo your homescreens. Big deal; that's something you would do anyway when hopping between ROMs (unless you have this covered already by using a non-stock Home/Launcher app which has its' own backup/restore capability)
C) Just wait a little bit - your ROM Dev will probably release a version based on 4.2.2. At that time you can do some stupid thing like overflashing the replacement ROM without wiping.
Unless you know exactly what you are doing, running a modified OTA with *all checks* suppressed is a seriously brain-dead idea. (Removing only the build version check should allow alternate recovery use - but for goodness sake, the OTA nukes the recovery anyway, so what's the big deal about putting the 4.2.1 stock recovery back in place ahead of the OTA?)
Look, running the Stock OTA is going to remove your recovery and very likely disable your root. You are going to need to put your recovery back and re-root anyway. Doing things the right way is barely more effort than what you are going to need to do the crufty way.
good luck

Moto G Rooted! Root Tool Inside

GO GO GO!
Superboot is a boot.img that when booted, will root your device the first time you boot (installing su and the superuser APK). No need to flash any partitions, no messing with the contents of your data partition, no overwriting the shipped ROM on your device, just boot the boot image using the instructions below and you're done!
YOU NEED YOUR BOOTLOADER UNLOCKED TO CARRY OUT THIS PROCESS. It's easy using fastboot, which is included in the download below. The instructions on the Motorola site are very straightforward - visit this page to get started. Unlocking the bootloader will wipe your device.
This Superboot installs SuperSU version 1.80. Note that rooting may affect your ability to receive future OTAs, reverting back to stock is easy enough. We'll cross that bridge when we come to it.

Props and thanks to [email protected], i can now consider buying this phone

i have a problem .... mmy cel is unblock but no rooting u.u

Rooted successfully, but I can't encrypt my phone now; it says "Encryption unsuccessful" and offers to erase everything. I reboot the phone instead without erasing and it boots normally.
Any ideas on how to solve it? It's kind of critical, since i can't use my email without encryption

can confirm that this is working, done in under a minute

I was able to get it working only after reflashing stock http://forum.xda-developers.com/showthread.php?t=2542219&page=3 then encrypting and then reflashing superboot.
So maybe it is worth updating instructions:
1) Unlock bootloader (wiping all data)
2) Encrypt your phone
3) Flash superboot

Thanks! only a question... If i unlock the bootloader and root the moto g, will I still receive the kitkat OTA update?

still not rooting
unlocked the boot loader, tried to root with super boot, but didnt work, flashed to generic uk, tried to root again and it still wont say rooted or show the su app, please can someone help?!

Rooted...wireless tether working with wifi router app. However, I got notified of 4.4 update today and it downloads, starts install, then fails.

5.0.2 - Experience and Discussion

Thought it would be good to have a thread dedicated to 5.0.2, instead of sifting through the 5.1.x Rolling Out and Stock OTA threads.
Got the prompt and updated this morning. Took about 10 minutes -- 3-4 minutes to install the updat and then a good 6-7 to go through app optimization (for 120+ apps).
Haven't had a chance to put it through its paces yet, but interested in what others experiences are. Improvement? Same old?

Screen flicker possibly gone? Was pretty bad before on mine, haven't had it since update now.

This will sound dumb probably: I am stock rooted with TWRP recovery. My N9 has a notification that update to 5.0.2 is available. As far as I know from reading guides and tutorials, I can't accept the OTA right? I have to manualy flash factory image? But how am I about to do that if the factory image for Wifi N9 5.0.2 isn't even available?
Thanks in advance.

You basically have two choices:
1) Flash the stock 5.0.1 system.img (this will install stock recovery) and boot.img, then vendor. Img then take the OTA.
2) Wait until Google posts the factory image.

Actually, you will need to flash three things from the LXR22C 5.0.1 factory zip ...
system.img
vendor.img
boot.img
and if you have TWRP, then also recovery.img
once all these are stock, then you can take the OTA.
After the OTA, you can either reflash TWRP, or just simply fastboot boot it, then apply the latest SuperSU zip from chainfire's web site, and you'll be back to stock and rooted.

Can't say i've seen much of a difference
then again the update was only 23MB. What Google are thinking atm I'd love to know.

Ive tried the ota 3 times now and every time it 'errors' in recovery while flashing, I'm flabber gasted this is how Google now treats its nexus customers.

Ok I'm going to update my vendor
if any one wants it just tell me

Something else ... if you attempt the OTA once, you're done ... you can't re-attempt it unless you reflash back to original 5.0.1 stock.
It checks System first, and updates it ...
Then it checks Vendor, and updates it ...
Then it checks the boot image, and updates it.
So you you fail the vendor test, it's already updated System, and it won't run again.
You have to reflash system.img, vendor.img, AND boot.img before you can try again.
A much smarter method would have put the three verification steps one after the other, but obviously Google did not write the script that way.

I think it's just some bug fixes. This is the only Nexus not moved to 5.1.1 by now, it's also the only Nexus using the K1 chipset. Not sure if the two are related, but it seems reasonable that they are running into some nVidia issues. 5.1.1 isn't out for the Shield tablet either.

ok guys updated to 5.0.2 just to get the vendor.img. it was hard lol

I appreciate this. Coming from Nexus 6, vendor.img doesn't exist.
And on Nexus 6 when flashing the stock system.img it checks recovery and if not stock will automatically flash recovery.img. Is Nexus 9 the same?

When will my Nexus 9 LTE Model get this?

I know man I'm crying inside

Ok so I got my ota update and downloaded it. Now my Nexus 9 keeps trying to come on,then saying android updating apps, then shutting off and restarting , and then repeats the same thing ! I never rooted or flashed anything ! Its completely stock ! WTH ! Help !!!!!!!

Update showed up when I turned mine on, ended up bricking my device.
Would show the spinning balls and nothing else, tried wiping cache, factory reset and still ended up at the spinning balls. Google sent me a new one, but I really wish I could just return the stupid thing.
I'll never buy another "premium" Nexus tablet again, the only way I buy another is if they give us another Nexus 7 like device.

I'm doing a factory reset .It seems it still on android deleting screen for 10 min already. Is it frozen ??

Boost E4 1766 Only Boots to TWRP

-Screwed up somewhere as my goal was to install LineageOS and try to use it on an At&t mvno.
-Package was unopened for months, so it still had the older firmware.
-Everything seemed okay after I unlocked the bootloader.
-Then I installed TWRP.
-Did a backup of everything using TWRP before I was going to try and root the device.
-I knew something was wrong when no verity opt encrypt and Magisk gave some error message and failed.
-Now whenever I boot the device, I get a N/A in the top left corner and then goes into TWRP.
-Restoring the backup using TWRP did nothing.
-I thought this would be the solution (dd if=/dev/zero of=/dev/block/bootdevice/by-name/misc bs=1M), but I get the bad key first and then N/A before going back to TWRP.

What should I do now?
Any help would be appreciated. Even links to other posts that dealt with this issue is fine. Be aware that my skill level is only a little better than following Youtube videos.
Thank you.

N/A is normal. It will be there forever after you unlock bootloader. Did you format data in TWRP and type yes to format?

Thanks for the reply.
As far as I know, I did not format within TWRP. Is that my next step? If not, please advice what should be done next.
My concern is something is wrong because both the suggestions you gave in that other thread did not result in the phone booting to Android properly.

once you flash TWRP you have to flash a no verity zip and probably magisk and definitely format data to remove encryption for your phone to boot.

Installing no verity zip and magisk produced the following. Did I do this properly because there looks like multiple errors?

I can't read that, LoL. Maybe... Failed toount data? That's because you're still encrypted.
Put the zips on external storage. Format data, type yes.
Now reboot recovery (not system) then flash the zips.
And you can take screenshots in TWRP.

Thanks so much.
I followed your instructions plus the one from the other thread. Phone is now able to boot to the stock Android. I guess my next step is doing a little more research before trying to install LineageOS to see if the phone works well enough on a USA GSM mvno.

One more question please.
On the E4, are the system firmware updates mandatory? I read that users are first notified and then forced to take the update even if you Disable Automatic System Updates.
Is that true? I wish to stay with the old firmware because people have posted that the new firmware eliminates any chance of using a USA GSM sim on a Boost 1766.
Thanks.

Use caution going with a custom ROM on this device, especially with a mvno. You may score far more hurt than benefit. Also consider what you are trying to accomplished going with custom ROMs given the clean stability of Moto stock ROMs. Toss in Xposed framework and a few modules like Gravitybox for full control/customization.
OTA updates can not be processed with a custom recovery (one of several prerequisites that your device no longer meets). You may get notified but the update won't install; you'll be dumped into TWRP. You can easily disable the update engine and corresponding notifications on a rooted device.
