[Nexus 6  General] VivaErBetis:
There is a procedure to fool OTA system in order to make it receive the OTA again. So you have a second chance to grab the filename and make a lot of people here happy :)

Update: Thanks to [MENTION=2203685]Sleeepy2[/MENTION] we know this method works in the nexus 6 :good:

DISCLAIMER: It's an unharmed procedure, but be warned, you will change build.prop so anything (bad) should happen if you do it incorrectly, most probably a bootloop.

If you have doubts, don't do it

.

Needs to be rooted.

So if there is a brave enought one, the procedure is just to change two values of the /system/build.prop file to make it looks a previous android version for the OTA system.

For instance, If you have received to OTA to LMY47M your build.prop file will have these values:

ro.build.date.utc=1425686543

and

ro.build.fingerprint=google/shamu/shamu:5.1/LMY47M/1774234:user/release-keys

If you change these lines by the equivalent lines from another version of android, the OTA system will check the OTA availability with the other android version. So, If before receiving the OTA your android version was 5.0.1 LRX22C you can change both lines with:

ro.build.date.utc=1416527965

and

ro.build.fingerprint=google/shamu/shamu:5.0.1/LRX22C/1602158:user/release-keys

That are the LRX22C version lines.

Save build.prop file and reboot your nexus 6

.

Once rebooted check for OTA updates (It will be checked as LMY47D) and download it, if it's not downloading yet (don't apply the OTA, just download it).

While it's downloading, or even after it's download, open a terminal emulator (for instance this one: https://play.google.com/store/apps/details?id=jackpal.androidterm) and execute these two commands (will ask for superuser permission):

su

logcat | grep zip

And wrote down the OTA link for us :)

When you finish just revert the build.prop changes done and delete the file /cache/update.zip (it's the OTA downloaded, and you don't need it), then reboot your system to leave it in it's normal situation.

Thank you very much in advance.

And, If you are kindly enough, you may check for the rest of OTAs from other android versions (the LMY47E OTA to LMY47M should be very useful too). Here are all known versions build.prop lines to play with:

LMY47M
ro.build.date.utc=1425686543
ro.build.fingerprint=google/shamu/shamu:5.1/LMY47M/1774234:user/release-keys

LMY47I:
ro.build.date.utc=1425442825
ro.build.fingerprint=google/shamu/shamu:5.1/LMY47I/1767468:user/release-keys

LMY47E:
ro.build.date.utc=1424577649
ro.build.fingerprint=google/shamu/shamu:5.1/LMY47E/1748839:user/release-keys

LMY47D:
ro.build.date.utc=1424322888
ro.build.fingerprint=google/shamu/shamu:5.1/LMY47D/1743759:user/release-keys

LRX22C:
ro.build.date.utc=1416527965
ro.build.fingerprint=google/shamu/shamu:5.0.1/LRX22C/1602158:user/release-keys

LRX21O:
ro.build.date.utc=1415319727
ro.build.fingerprint=google/shamu/shamu:5.0/LRX21O/1570415:user/release-keys

LNX07M:
ro.build.date.utc=1414346119
ro.build.fingerprint=google/shamu/shamu:5.0/LNX07M/1543455:user/release-keys

-----

KXH21.6-F1.12:
ro.build.date.utc=1416355004
ro.build.fingerprint=motorola/shamu_factory/shamu:4.4.4/KXH21.6-F1.12/25:userdebug/release-keys

Most of them will give you old and known OTAs, but some will give new OTAs for all of us. And the final test build probably doesn't give any OTA :)

Thanks and best regards.
