Flash stock firmware on locked phone - Droid Ultra Q&A, Help & Troubleshooting

Hey guys, I have a quick question maybe you guys can help me with.
I have a droid Maxx that is exhibiting some issues and I was wondering if I can use RSD lite to flash stock FW to it.
The phone itself is locked and in a stock state. Is it possible to flash stock FW or would I need to unlock the bootloader with something like Sunshine first?
Or would there be another way to flash stock FW not involving RSD?
Thanks

[Q] Restoring to stock?

I've just received a used VZW Razr HD (Maxx) on trade. It's rooted with unlocked bootloader on 4.04 (don't have the build number handy). It is not a developer version of the phone.
I understand I will lose root, but I wish to restore it to factory stock 4.1.2. While I'm not new to Android (also have a GS3 and a Droid Inc.), I am new to Motorola phones.
What's the procedure for flashing this thing to stock, locked bootloader and all? Have a source for the stock ROM? Any help is appreciated.
Matt's util in original android development should work for most common devices. Make sure your phone is the right variant and flash the stock ICS and receive the otas. Or you could use like rsdlite (which is available on the forums) and flash the stock 4.1.2 firmware on. Look for some of the devs other posts to figure it out. (The firmware is also on the forums).

Thanks. Does flashing the stock 4.1.2 firmware also restore stock Verizon apps ("bloatware") and any changes made to the bootloader? I presume I can flash this despite changes made to stock apps (missing .apk's, frozen apps, etc.)?
How about returning to stock recovery? What's the procedure there? Can I find the necessary .zip file and flash with Matt's utility?

[Q] SBF 9.30.1 on unlocked bootloader

I hope this is an easy answer...
I want to SBF my Droid Razr Maxx HD to full stock. I have an unlocked bootloader and it is currently on CM 10.1.3. If I SBF this phone with RSD Lite and the firmware (from http://sbf.droid-developers.org/phone.php?device=5) will I still have the unlocked bootloader and the ability to flash other roms if so desired?
yes
Thank you.
EDIT: I have successfully brought the phone back to full stock.

[Q] Anyone know where I can grab the stock recovery?

I need to flash the stock recovery for my Maxx, but I'm not sure where I can get it. Any ideas?
why do you need it (if you are in custom recovery and hence rooted)? Are you getting ready for the OTA? I hope you have unlocked your bootloader...
Then its better to return to stock as a whole and the details are here... Yes, the recovery will be stock one and you can receive OTA without any issue. BootLoader will still remain unlocked. Re-rooting is also as simple (even after ota MOSTLY) as flashing TWRP recovery..
here it is, grab it.
its 4.4 droid maxx stock recovery.
You can find all stock firmwares here:
http://sbf.droid-developers.org/phone.php?device=4
Download the 4.4 file and pull the recovery.img file out and flash it with fastboot

[Q] Can i do a OTA update?

Hey guys,

But i got back to stock with this GUIDE and i got no rooted device and no custom recovery but i still have the unlocked bootloader, i also have a other stock image of the moto then normally! (I have the 210.12.32.falcon_umts.Retail.en.US version) and i need the global gsm version xt1032 if i am right. But my question is, can i get ota updates now? because i want android L!

Sorry for bad english
Your warranty is just invalid but you'll be able to perform an ota update. If you have doubts flash a stock 4.4.2 firmware and update it via ota, I'm sure you'll be able to do it. You'll enjoy Andoid L, don't worry

Having an unlocked bootloader has no adverse effect on the ability to update via OTA. You can even be rooted, although, you will more than likely lose root upon updating, which shouldn't be too difficult to get back. The only things that would affect updating via OTA is if you have a custom recovery, or if you've modified/deleted any system files/apps.

[Q] Help upgrading to KKBL. OTA or Flash?

Hi,
It's been years that I've been living with the XT925 on CM11 JBBL and as I've been following latest developments on CM 12.1 and want to give it a try.
I've been searching for the past week on how to safely perform the bootloader upgrade so I can flash CM12.1. As it turns out there is a lot of disperse information on how to do it, followed by scary cases of soft bricked devices.
Current device status:
- Bootloader Unlocked
- Rooted
- CM11 M12 JBBL
- Everything works fine
What I already know:
- I have to Unroot my device
- Need to flash stock 4.1.2
- Must check if everything works once in stock
What I need help:
- Should I download OTA via the stock firmware?
- Should I flash stock recovery?
- Should I perform the update from the device or should I extract the OTA and change something and then flash it manualy?
- Is there any tutorial that I should've found on my searches?
On a sidenote: is there any chance of my bootloader to be relocked and/or loose any chance of future root access due to the OTA?
I believe that as people realise that CM12.1 is stable some noob friendly thread to the ancient JBBL's out there would be much apreciated.
Thanks in advance!
If I were you, I would just flash straight to KK with RSD or House of Moto. If you go this route, you won't need to flash back or reinstall stock recovery. Flashing the FXZ will reinstall stock recovery, but if you use House of Moto you can use an option to flash aftermarket recovery. Flashing shouldn't relock your boot loader, either.

In order to flash straight to KK I need to obtain it via OTA download while in Stock JB.
I haven't found any KK image laying arround, so this might be the only route.
Any other advices will be much apreciated RikRong.
Can you find the firmware on MotoFirmware.com, when it's actually up?
Try this: http://motofirmware.center/files/
