[GUIDE][Osprey] Fastboot Flashing Factory Firmware Images

[Rohi09]

Yes, in Android settings. You cannot unlock Bootloader without requesting the unlock key. I'm not saying to request anything, only enable that setting.

i'm wondering, what does enabling that do?

It gives you the option of unlocking Bootloader. It's not complicated. If it's not enabled, you cannot unlock Bootloader even if you had the unlock key. You can disable it again later.

okay, then if something goes wrong and i cannot boot into system then i can ask for unlock key and unlock the bootloader and flash a custom recovery. thanks

Thanks for the guide,
managed to guide my friend through flashing the US marshmallow update on his bootloader unlocked British xt1451

please note, we did not use the following commands

fastboot flash bootloader bootloader.img
fastboot flash recovery recovery.img
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn

Thanks again

If device is rooted (and custom recovery installed) and I'd like to unroot, would be enough running these commands?:

fastboot oem fb_mode_set
fastboot flash recovery recovery.img
fastboot flash system system.img_sparsechunk.0
fastboot flash system system.img_sparsechunk.1
fastboot flash system system.img_sparsechunk.2
.
.
.
fastboot flash system system.img_sparsechunk.N
fastboot oem fb_mode_clear
fastboot reboot

I'd like to avoid loosing user programs and data

You cannot - everything has to be erased or Android will not boot. A factory firmware images is not an OTA Update. You must perform a 'Factory data reset' in Android before flashing any Firmware Image, and include the command: fastboot erase userdata.

Yes and no.
I mean reflashing same firmware.
If I reflash same firmware, but only system partition (or all files), I think it could work (to unroot) without erasing anything.
In nexus 7, reflashing same firmware without erasing user data is the right way to unroot.

Three days ago I upgraded from 5.1 to 6.0 without performing 'Factory data reset' and Android boots ok

With Moto G (3rd Gen) in particular - not doing a 'factory data reset' has prevented Android booting for many people. It's also my experience with Moto G generally that not erasing userdata can introduce a wide range of issues, from very minor to very serious. I am now of the opinion that if you have not done a 'Factory data reset' in Android and erased userdata during fastboot flashing - you have not flashed Android properly. For best performance / experience, do what I say.

Is there any 6.0 firmware that I can flash on my XT1541 with locked bl? I remember that I was able to flash the indian lollipop on my 1st gen eu moto g

edit: I've read that with locked bl there are to many problems, I'll wait : /

 

[beworld16]

I have flashed 6.0 firmware using fastboot commands on my moto g3 xt1550 and
Rooted using twrp.

Now can i re-flash 6.0 firmware using fastboot commands ?

You can flash fine with locked bl. But you must do a 'Factory data reset' in Android settings before flashing.

Yes.

Yes.

But which file should I flash? XT1543? If anything goes wrong if I've enabled "oem unlock" from dev setting I should be able to do something?

It would be best to wait until the correct 6.0 firmware for your phone is available, but if you cannot wait, XT1540 Retail US would be a more sensible choice. Yes, 'oem unlock' will allow you to unlock bootloader in the event something went wrong.

So should I flash the same way as this person with an unlocked bootloader? If it works on an unlocked phone with the bootloader unlocked, it'll definitely work on a locked phone? Also, should I factory reset from fastboot, manually with recovery, or from the OS, which will probably boot back into the OS when it's done?

Many people with locked Bootloader have flashed these firmware images. It is essential you do a 'Factory data reset' in Android settings (not recovery) before flashing any firmware image. Then follow the instructions in first post.

But doesn't it reboot into Android after factory resetting? Also, can I skip the bootloader?

Have you read post where you downloaded ROM???? It says that you may have more o less sparsechunks, it depends your device model... So, YES, it's fine
Please, read carefully before asking
