[Q] Official (not manual) lollipop OTA on unlocked moto g xt1033

So, the situation is I have moto g xt1033 with :- unlocked bootloader, rooted, stock rom 4.4.4 kitkat (i mean no custom rom). and fastboot flash mode 41.13 2014-06-16 and philz touch 6 clockworkmod v6.0.4.7
I want to know how to update to lollipop with official OTA update (not manually or sideloaded)?
Why I am asking this?
I got the prompt of official OTA available on my phone and then i clicked yes and downloaded the update. But when i clicked on install, it went in bootloop. It boots on the philz recovery mode and then nothing happens just restart again whatever i select.
As of now, as I backed up, I recovered to the before state of the phone. Do I need to lock the bootloader again or what? The official OTA update is not for me? Then how to get lollipop? I read the soak test etc threads but why not official update ?
Locking the bootloader won't do anything,so don't lock it
Ota update requires:
1.Stock firmware(unmodified and unchanged or tampered)
2.unrooted
3.Stock recovery
That probably happend becuZ your KitKat firmware was modified and you have custom recovery,root..
So just reflash the stock firmware
Do that on your own risk as failing this might brick your phone
Thank me if I helped
Thanks mate for reply.
1. I have stock firmware KK 4.4.4 (though xposed framework & few modules are installed currently)
2. Rooted
3. What is stock recovery? (m noob here)
And i guess reflashing the stock firmware wipes out all user data & apps, right?
Any other alternative which does not wipes out my data?

Actually there is no other way you could do it
i tried everything i could to stop the wipe procedure but it obviously wiped everything
you just backup everything you have got on your internal and external sd card ..
1.Stock Recovery:: Android devices come with Google’s recovery environment, which is often referred to as the “stock recovery.” You can boot to the recovery system by pressing device-specific buttons as your phone or tablet boots or by issuing an adb command that boots your device to recovery mode. The recovery menu provides options to help recover your device — for example, you can reset your device to its factory default state from here. The recovery mode can also be used to flash OTA update files.
2.Custom Recovery::A custom recovery is a third-party recovery environment. Flashing this recovery environment onto your device replaces the default, stock recovery environment with a third-party, customized recovery environment. This is a bit like flashing a custom ROM like CyanogenMod — but, instead of replacing your device’s Android operating system, it replaces the recovery environment.
what you have to do is:
Find the Kitkat official update on the internet accrouding to your [Build number],[model number] [system version] you can get this information in about phone....
If you have asia retail then follow this method http://forum.xda-developers.com/showthread.php?t=2700502
ok Here what i am planning:
1. Uninstall all modules & xposed framework
2. Unroot using supersu
3. Restore/reflash stock recovery (just recovery not whole firmware as I already have stock rom)
4. Install the update either manually via recovery or using auto install.
Am i on right path? Pls help me on step 3, any link or step-t-step guide? I couldn't find one, every post is abt restoring whole firmware.
TIA. Cheers !!

[Q] Q] [ROM][WIP][NAND] Omni 4.4 - 11.12.2014

Hello to the Forum
I am new on the Forum i do not know exactly how it works Please excuse me
I have a SAMSUNG 8500 with Bada
I would like to suppress Bada and replace it with ANDROID Kitkat 4.4;4
I Tried the procedure listed in the Topic ROM][WIP][NAND] Omni 4.4 - 11.12.2014
i could Flash Bootfiles Startkernel and FOTA with Multiloader
i do not understand the following and I do not want to have my Phone Bricked ! - -
Do I have to proceed the Android recovery immediately after that step Before loading the SDCard ?
ROM means the Android File ? Where can I get this ROM ?
What Does it mean > choose zip with ROM ?
Do you have to set the Phone in - DOWN LOAD MODE to make this procedure - vol low -+ camera + power ?
Thank you in advance for your Help - Georges
I'm not sure about the procedure you followed but did you -
1. Flash a custom recovery.?
2. Wipe data and cache.?
A ROM is the OS (operating system like KitKat lollipop and so on) you need a custom recovery like clockwork mod to flash a ROM. You even need to unlock the boot loader on some phones. It's best if you ask in your device forum. Or such for the stuff I mentioned. I'll list them for you again.
1. Unlocking the boot loader (your phone may not need it too, searching for it over us good)
2. Rooting
3. Custom recovery
4.a ROM (you need a custom ROM to install right.? xD search for cyanogenmod)
MAKE SURE TO PROPERLY BACKUP YOUR STOCK ROM BEFORE FLASHING OTHER ROMS.
Happy flashing and leave a thanks

Kitkat-lolipop firmware base switcher for a6000

We all like to flash new custom roms in our Lenovo A6000.
Some time new custom rom release on Lolipop base which is very attractive and we might wanna check it out.
Unfortunately the new custom rom might be buggy and we may be forced to revert back to kitkat or whatever os you were before.
Analysing the present custom os' available for lenovo a6000, many rom authors says that the phone should be currently running on kitkat/lolipop before instaling that particular OS.
I found a work around to avoid flashing of 1 GB stock rom (which is time consuming) to get into kitkat/lolipop build. You just need to flash a very small sized zip file which contain the core system files that are essential .​Steps
From Kitkat to Lolipop
Download Kitkat named file attached below
Copy it to your sdcard
Boot into recovery
Flash the copied file
flash whatever lolipop custom rom you like
Voila all done and reboot
[*]From Lolipop to Kitkat
Download Lolipop named file attached below
Copy it to your sdcard
Boot into recovery
Flash the copied file
Flash whatever kitkat custom rom you like
Voila all done and reboot
Note: Not for Lenovo A6000 Plus
Status : Stable
Looks useful but I'm on A6000 plus. Can you port this for us?

Thank You Rahul S Nair for Your Efforts and Hard Work,
Unfortunately It's not working for Me on A6000,
i was in CM 11 4.4.4 (Unofficial),
I just flashed your Kitkat based system by you.zip via TWRP and it's succesfully installed,
Then i flashed Xenon HD from ( http://www.techolaty.com/34356/lenovo-a6000-plus-xenon-hd-custom-rom-32-bit.html ) which is based on Lollipop 5.1, > it showed installation completed.
and i rebooted my device.
But Stucked on Lenovo Logo.
Waited for more than 5 - 6 Minutes, Done 3-4 Times, But no more Changes_Any remedy?
But after this i can install Kitkat based ROM, installed CM 11 again without any changes,

Unable to get OTA Updates installed on TWRP - Need to go back to stock recovery

Hi All,
Background:
Installed TWRP recovery to downgrade to KitKat from Android ver 5.0.2 / COS 12.0 YNg1TAS17L
( I guess the changes in lollipop made me to do so).
But after installing TWRP, for some reason or other I did nothing and now the issue is the OTA are not getting installed. From other similar thread I know that we can download the OTA zip and install through TWRP and I am not looking to get into that...as I am giving this device to my family.
Help Required:
1) Is there a way to uninstall TWRP and go back to stock recovery without losing any data?
( Is it as simple as flashing recovery image from the Stock ROM?)
2) Using the OnePlus tool kit can we flash the stock ROM which will also restore the stock recovery?
(If so is it possible to flash the latest ROM 5.1.1 or CM12.1)
I just need guidance here with steps on what will be the best and safe approach without frying up my device.
Please suggest

Numerous other threads on the same subject... I don't understand why you are not ready to flash the OTA through TWRP but you are through stock recovery... It's the same thing... Don't use toolkit, they are the ones, in 99% of the cases, that "fry" your phone... As soon as TWRP is installed no OTA will automatically, you will have to flash them manually.
