Hi guys,
I'm running my Moto G 16GB on Kitkat 4.4.2 system version 175.44.1.falcon_umts.Retail.en.DE. Today it offered to download and install the latest OTA update (called 176.44.1.en.DE). I started the download and tried to install it.
After downloading the update was placed in /cache. The file name was 'Blur_Version.175.44.1.falcon_umts.Retail.en.DE.zip', which surprised me. I was expecting something like 'Blur_Version.176.44.1.falcon_umts.Retail.en.DE.zip'.
When I tried to install it without removing root and without going back to stock recovery it ended with a signature error in CWM. Installing the untrusted zip manually didn't work as well - as expected.
Then I tried to follow advise from other threads and went back to stock recovery (extracted from a full install package 'Blur_Version.175.44.1.falcon_umts.Retail.en.DE' - 444MB) That seemed to work and the install of the OTA update went fine before getting stuck on the boot animation on the first boot. It sat there for 10 minutes before I rebooted and restored a CWM backup.
I'm running out of ideas. Some say it's sufficient to go back to stock recovery temporarily. Others say you need to go back to full stock.
I have to repeat that I'm rooted and that I've de-activated a few unused apps (mainly harmless google stuff (hangout, search, music and so on) and Motorola Assist, Migrate and 'Context Services') .
Are there further findings about what stops the OTA from succeeding?
Many thanks in advance,

If your phone is rooted or there is a CWM installed or there is any change in system files then ota will fail till you flash stock rom. You can't just bring back stock recovery. You have to "delete" root as well.
There is some info http://forum.xda-developers.com/showpost.php?p=47495650&postcount=6
I will post my case here, I had the same problem, I had CWM and root and when I rebooted to update I get installation failed and boot loop.
Then I just flashed stock recovery (only) rebooted and now I already have the update installed

Hi, thanks for your replies. Because of your report and others, who state the same (installing stock recovery only to get the update working) I was hoping to get around going back to full stock. It always takes a lot of time to configure the phone the way it was configured before essentially wiping.
Just to repeat what I did: when I try to install the OTA while CWM is installed there's just an error message in CWM, the update fails, but the phone is working normally afterwards. It's just not updated.
When I try with stock recovery the update process finishes without errors, but the phone get stuck during the boot animation.
Maybe there's a way to fix the boot loop?
Looking forward to any suggestions
Cheers, Kleo2
I tried again and found a way without going back to full stock.
1. flashed stock recovery from full 175.44.1 image
2. let the phone download the OTA and restart to install it
3. ota install in stock recovery went fine
4. reboot -> stuck on boot animation again
5. flashed CWM and wiped cache AND dalvik cache
6. next boot took longer than normal but got past the boot animation
7. android optimized/cached my apps and then started normally
8. version is now 176.44.1 and the phone seems to work normally (after 30 minutes of usage)
Hope that helps someone and that I won't have issues going forward because I did it this way.
Cheers, Kleo2

I UPDATED my rooted Kitkat Tesco version SUCCESFULLY! and still rooted.
What I did:
1. install Motorola Device Manager (RESTART computer and telephone)
2. downloaded MotoTool
3. Made a Nandroid backup in CMW, made a backup with MotoTool too. Just in case
And deactived (did not uninstall) my Xposed framework modules (if you dont have it, you dont need to)
I have some system apps disabled, but didnt re-activate it. (was too lazy haha)
4. downloaded the correct ROM from: http://sbf.droid-developers.org/phone.php?device=14 (Tesco UK 4.4.2)
5. unzipped the ROM and rename and overwrite the recovery.img to the exact name as in the MotoTool All In One 2.6\Data\KitKat\StockKitKatrecovery.img (Just for sure it's the same as my ROM, I dont know if all the ROMs have the same recovery sooo )
6. started MotoTool, unplug&replug device. Checked KitKat option in the program, did a connection check, it was okay. Did a NORMAL restart via progam. You have to grant permisson on your phone.
7. after reboot, rebooted the phone to FASTBOOT.
8. Checked Stock Fastboot in the program, it flashed succesfully. Then I went into recovery (1×down volume, then 1× up volume) checked if the recovery was working. It was working (android logo+ no command error message)
9. reboot (long press power button)
10. Updeted OTA, settings/inf./update.. blabla okay okay next next. Wait until it downloads (only 7.9 MB )
11. wait for the update to be done, then it reboots, then apps are being updated. Everything looks fine and working
+1 flash CMW or other recovery again.
Hope this helps! I was afraid to do it too. I'm not used to MotoTool and other Motorola stuff because I had a HTC Desire, it was much simplier with that. But no risk here either! Good luck!
So I am trying to put back my stock recovery so I can take the OTA, but after I flash the recovery and try to reboot to it, it says "No Command". I have reflashed TWRP and then the stock recovery again with the same result. The phone itself will boot fine, but I can't install the OTA as it gets an error part of the way into the install. Any ideas? I have the 1034.
EDIT: Well I remembered I did the H+ mod, so after reverting that the OTA flashed I had Faux Kernel before hand, but after reflashing it my wi-fi wont enable, any ideas?
Thanks!

Wiping cache and dalvik cache did the trick for me. You saved my day
Please please help
I have the same problem. I've tried to update the new OTA and failed. After restoring full stock rom, the system simply doesn't boot!
I had Faux Kernel and GravityBox but I didn't revert anything. I thought that a full stock rom would clear all system settings.
This is my version of stock (Blur_Version.174.44.9.falcon_umts.Retail.en.GB) and I tried to flash it several times now. No success. I get stuck on the boot logo.
I tried to downgrade to 4.3 using version Blur_Version.14.71.8.falcon_umts.Retail.en.GB. I was able to boot and see the initial setup but I have no WIFI! I was trying to install 4.3 then try to update via OTA but OTA only works with WIFI so I'm stuck.
I also tried installing the 24th Feb nightly build of Cyanogen and the device also booted but with no WIFI.
I really don't know what to do! Please help me. I've tried other stock images out of despair but none with sucess.
Does anyone have a clue to what might be to problem and how to revert it?
Thank you

Before flashing stock ROM try to clear/format all your partitions with a custom recovery!
Sent from my XT1032 using xda app-developers app
I installed the OTA update using the CWM recovery but not root, I changed the update-script to not give error during installation

At part 8, I am getting an image of the android guy with his stomach open with a big red '!'. That's 'no command' right?
Any ideas? I have no idea what I am doing
Guys, a really easy way to update is:
1. Install Philz recovery - http://forum.xda-developers.com/showthread.php?t=2639583
2. Reboot and then download the OTA update when prompted - select Install when prompted
3. It will now reboot into Philz recovery, install the update and reboot
4. You'll see Android is Upgrading...
5. Re-boot back into recover and re-install faux kernel
I have just upgraded my XT1032 on 174.44.9 en GB (rooted + faux008) to 176.44.1 using this... worked like a dream! All I had to do was re-install faux kernel as that was overwritten by the OTA, but Root was in-tact...
i have root, twrp recovery and faux kernel, the problem is only faux kernel? Or I must remove all? (root recovery etc)
Hi folks,
I'm a little kerfluffled if you will by the sheer number of threads - search isn't pointing me to a thread that deals with this - so apologies if this has been answered before.
I originally rooted my phone with towelroot. I kept stock but installed a few things like Xposed, greenify, gravity box, etc... (also i switched to ART some time back).
Once i received the OTA notification, I deactivated greenify and gravity box, then uninstalled them, then "unrooted" the phone using SuperSU. I did forget to reset my "startup animation" but otherwise everything seems fine. The root checker confirms that the phone is no longer rooted. Since i forgot to backup the stock animation i just renamed the .zip and now when i boot the animation just says Android (with a little animation regarding the color of the letters).
I then DLed the update, restarted and approximately 30 ~ 40% of the way through the update screen it freezes up and then i get the little android dude with his belly open and the red error triangle. The text below says "error" but provides no further information. The only way to resolve the issue is to power off the phone and then turn it back on. It goes back into 4.4.4 and works fine but i can't get past that error and have no idea how to tell what the error actually is.
Any suggestions will be appreciated! I would prefer to not have to wipe my phone if at all possible.
You'll must wipe your phone as I am. Then you'll be able to OTA update your phone.
I do exactly like you, but error appears every time in the middle of update process. After wipe everything was fine
Fastboot flash the new factory images one by one. Reboot the bootloader in between each image, just to be safe. Then use chain fire auto root. It'll take you about 20 min. You will lose all info on your device though.
To save your information, you need to get back to totally stock, unmodified 4.4.4. So flash that in fastboot, just don't flash the user data. Then you can accept the ota.
Even modifying the boot image will cause an ota to throw out an error.

Since I'm not concerned about root in Lollipop for now - if i can find the original boot animation and "reinstall it" so to speak - will that allow me to use the ota without having to wipe my phone?
Not for sure. To guarantee it will work. Fastboot flash 4.4.4 system.img, boot.img, and recovery.img.

okay thanks! i'm going to try and find the original boot animation somehow and if that doesn't solve the problem, i'm going to fastboot everything.
Just dont flash userdata, or you'll lose your setup.

I've got quite a peculiar problem with my Nexus 5.
Last night, I left my phone on charge. It was working normally and the software was functional etc. However, once I woke up, the phone was constantly restarting itself, and wouldn't load past the boot animation. I tried to load up fastboot to enter the TWRP recovery, however, the phone froze on the load screen. I should also add that my custom boot animation was replaced by the CyanogenMod mascot.
This problem has never occurred before, and I really haven't got a clue how to fix it. I tried to use WugFresh's NRT to flash a factory image of Android 6, however, the command terminal indicated that each process had failed. This did not restore the phone to its original condition.
I should also point out that I have been running a CM 12.1 nightly, which has been very stable and I have been using this nightly, without major problems (bar the infrequent system UI crashes) for a couple of months. It is obviously rooted and I have a Nandroid backup, which I can't access for aforementioned reasons.
Please could you help me with resurrecting my phone? I would be happy to clarify and elaborate upon any point of information.
Kind regards,
Sami
Have you tried manually wiping cache in fastboot or manually flashing a stock ROM in fastboot mode?

I actually have tried to flash stock Android ROMs, from KitKat to Marshmallow, however, this didn't work as there was a 'write failure' and CyanogenMod wasn't removed. I did erase the cache, but to no luck.
Sounds like the memory module on the phone is defective. I had a Nexus 5 that would constantly re-lock the bootloader after I reboot. I had another N5 where the bootloader remains unlocked and a full wipe in recovery would finish in about 3 seconds which is far too short.
I could only solve both problems by replacing the motherboard.
Hi All,
I have been searching and trying many different things to unbrick my Honor 6 (H60-L02V100R001CHNC00B316)
I have read all the posts here relating to bricked Honor 6's and none of the suggestions that I've tried have worked or are for my model.
Basically I had a perfectly working EMUI 5.1 stock install (unlocked, rooted) and wanted to try the stock EMUI 4 update.
I backed up my phone with TWPR and then unrooted and installed the stock update.
This was working fine, however I wasn't completely happy with it so I decided to go back to what I had.
I should have just flashed my backup, but I thought I needed to flash this 'rollback' file (H60-L02-L12_EMUI4.0_2_EMUI3.1.zip from https://mega.nz/#F!uopFUBJa!jp6hkjmftAKjQ8LrriwOTA!C4ZCVB5T) because it was there, but now my phone wont boot.
I can do all of these things:
Boot fastboot
flash system,cust,boot
Unbrick with MultiTool
Boot recovery
Flash custom recovery
Restore twrp backup
I cannot:
Boot into the system (the phone is stuck at the splash screen before the animated boot logo, no change after an hour)
Flash stock update via 3-button (freezes at 5% or gives error)
Charge properly, battery always low even after charging for hours
I'm presuming that something in that rollback file has overwritten something crucial and no stock updates are fixing it.
I'm considering using DC Phoenix but don't want to pay unless it's guaranteed to work.
Can any one make any suggestions as to what I can do?
Any help is appreciated.
Fixed you issue?
Issue is not fixed sorry, I gave up on it, but I still have the phone to try again if there is a solution.
Well, not fully bricked, but it's completely non-working just the same.
I've had the K1 for a few years now and have been fine with the standard, stock OTA updates. Recently though I've been seeing constant notifications that I'm short on ram and after uninstalling apps, deleting old files, it would work ok for a few days and then start complaining about low memory again. So I figured that something must be corrupt and now is a good a time as any to root and see about flashing a new rom.
I've owned many android devices over the years and have rooted and patched most of them. so I'm familiar with the tools.
This time however, I think I must have crossed something up somewhere.
What I did was this:
Grabbed the minimal ADB package and fastboot drivers.
Booted into the bootloader and ran the fastboot oem unlock. No problem.
From the nVidia site, I then grabbed and flashed the latest stock image and recovery, just to ensure I was on a clean slate. No problem.
Flashed the latest TWRP for the device. No problem.
Flashed SuperSU. No problem.
Booted into the stock system to make sure everything was still working and it was. But, this is the start of where I maybe hosed things up(?).
While running stock, I converted the SD card to internal memory, just so I wasn't having to mess with it later, not thinking that I'd have to do it again anyway after flashing a new rom.
Rebooted back to TWRP and proceeded to flash the new rom (AOSP Extended (AEX) 5.8).
I flashed it by way of the sideload method rather than from a zip file sitting on the SD card. This all seemed to work just fine.
Next I went ahead and flashed OpenGapps Mini. This resulted in an error 70 and after reading about it, it was a simple matter of going into the advanced settings in TWRP and extending the system partition. Did that and OpenGapps then flashed with no problem.
Finally I wrapped it up by flashing tegra124-tn8-p1761-1270-a04-e-battery.dtb and rebooted.
... Nothing. Now I know that when flashing a new rom, the first boot can take some time, but I let it sit for about 2 hours with no result. It didn't appear to be boot looping, but instead just stuck on the nVidia boot screen. Forced it to boot back to the bootloader and brought up TWRP. I obviously did something wrong, so I prepared to reflash the stock image.
Did the wipe, flashed the files and rebooted. Again, nothing.
This time however, not only can I not boot to the system, I now also can't get back into recovery.
No matter how many times I reboot, or attempt to reflash anything, it hangs on the boot screen when attempting to get back into recovery.
So I'm stuck. I've tried reflashing TWRP, stock recovery and stock system, with the SD card in and out, a number of times, all with no joy.
I can access the bootloader, so I can at least run fastboot commands, but that's all I can do. Without being in recovery, I can't access an ADB shell if I need to repair anything.
If you're still with me after this rambling mess, do I have any hope at all in recovering this thing?
Hi,
I think the problem is in the modified .dtb try flash the original file.

I'm also sort of in the same boat i had a custom rom installed and decided to go back to stock os and now i'm stuck at either the Nvidia Logo or the Fastboot menu there's nothing else it let's me do i'd take any advice at this point. I can use Fastboot commands and I've tried Flashing Twrp.img and also flashing all the stock os which goes through with no problems i reboot the device and it's just stuck at the Nvidia logo
Ps: how did you manage to get back into recovery
Hello.
I think i had the same Problem.
I Flashed a Custom Rom, MiniGapps and the tegra...Battery file and since then i had boot loop an the NVidia Logo.
The Problem was: i flashed the tegra-Battery.ZIP file!!!
I noticed that i have to unzip it and flash teh tegra-..battery.DTP file.
since then it booted up again.
the OpenGappMini was buggy. it worked with the Nano!
Hope this helps for you as well!
OMG you guys. I did the exact same damn thing. Flashed the ZIP instead of the DTP file. 100 million thanks to you. I'm going to give it a shot now.
It worked! I wonder how many other folks didn't realize it wasn't a zip to flash to dtb and bricked their devices.
