Long story short, I was trying out new kernels, got stuck in a boot loop, nothing would fix it, so I tried to restore back to stock rom. I did it manually in fastboot mode, but the bootloader .img would not write. It gave an error saying mismatched signatures. I redownloaded the image, I tried using a couple of different methods, like using toolkits and various commands, and finally, without thinking, erased the bootloader using the fastboot erase command with the intent of re-writing it, which obviously I can not do or I would no longer be here. It still boots, in the sense that I hear the notification on the computer that a device has been connected, but it shows up as NVidia APX in my list of devices on windows instead of Nexus 7 now, and the screen shows nothing. So... how screwed am I? If it is hopeless, is there any way to return/replace it (without using questionable methods)? Thanks.

You flash your bootloader? That's the last thing one should do. We only need to unlock it, not flash it.

It was already unlocked and rooted, etc, but I kept getting an error about it every time I tried flashing a rom, and the device wouldn't boot anyway, so I got frustrated and derped. I know that was pretty stupid, just wondering if there is any hope.

sounds just like your situation... unfortunately you will most likely have to return/exchange/RMA
I flashed the Eclipse ROM via safestrap and then restored the Eclipse ROM onto the stock ROM slot. For some stupid reason, instead of restoring the stock ROM slot before resetting the phone back to stock, I opted to use RSD Lite 6.1.4 and tried to flash the JB firmware (yes, I got into fastboot). When I tried to do this, the phone reboots past the Motorola M insignia, to the droid startup screen (with the flashing red light/circle), but does not get past the startup screen (yes, I gave it 30+ minutes to no avail). I also tried to reflash the JB firmware, but no matter what, I ended up stuck at the bootup screen.
For this reason, I tried to flash the ICS firmware instead (per instructions on XDA and other websites, I removed the lines in the XML file that had the word var, getvar, and oem). This did work! However, after RSD flashed the firmware, rather than restarting into the OS, the phone reboots into a black screen w/ the phrase "Fastboot Reason: Sticky bit factory_fastboot" at the very bottom. Anytime I try to restart the phone, it automatically boots into this screen. If I hold the volume up and down buttons, together w/ the power button, I am able to get back to the option to start normally.
When I tried to do the OTA JB update, the phone downloads the necessary files, but when the phone tries to reboot to install the OS update, it goes back into that black screen and does not install the update. Also, when I finally do get back into the OS, the phone then constantly reboots as if it were trying to install the OTA JB update.
Does anyone know what "Fastboot Reason: Sticky bit factory_fastboot" means? Also, if anyone knows how to "fix" this issue, I'd greatly appreciate it. If the fix requires command line work (like in this thread), I'd greatly appreciate if someone could walk me through it step-by-step, as I am not familiar w/ the command line process.
Thanks!
Edit 1: The next step I will try is to get root back on my phone, install Safestrap, and see whether I can flash a backup that I previously had.
Edit 2: In some threads for other Moto phones, there is some discussion regarding using ADB to fastboot/flash the stock ROM. Anyone know how this is different from using RSD? Also, can anyone walk me through HOW to ADB? I have zero knowledge in this regard.
Have you tried holding the buttons down to enter fast boot again and reflash? Worth a shot if you haven't. You could also attempt a factory reset from the boot menu. Maybe the corrupt file would correct itself.
You should definitely take the time to learn some ADB; at least a working understanding. It helps down the road.

Yes, I attempted to reflash on multiple occasions, both using the stock ICS and the stock JB roms. I must have reflashed close to 10x at this point. In any case, no matter how often I have reflahsed (including after doing a factory reset from within the OS as well as from within recovery), I still get the error. The good news is that I was successfully able to flash the JB ROM and have the phone OS actually start up, whereas, a few days ago, it would be stuck at the red circle/eye thing.
Furthermore, I attempted the command fastboot flash system [system.img], and I got the error:
(bootloader) Variable not supported!
target reported max download size of 31457280 bytes
error: cannot load '[system.img]': no error
I saved the system.img in both c:\android, as well as the internal SD card of the phone.
The other good news is that I am still able to use the phone if I get into the boot menu and ask the phone to boot normally. However, I am now unable to get root, and anytime I need to restart the phone, it gives me that error message.
I have also tried the command fastboot reboot bootloader but continue to get the same error message.
OK. Find a JB leak zip or current stock JB zip, access the screen where it asks for AP Fast boot and recovery, choose recovery, then volume up I believe when the phone shows the android with the red exclamation point.. Then choose update with zip. Search your SD card and install. It's worth a try in this manner in case you haven't already.
That's odd that your phone didn't respond well with RSD.

You need to use an updated fastboot binary for the new larger images in these devices.

Skippid, thanks for the suggestions. I tried your method as well. Went into recovery, selected to update from external SD (or something to that effect), selected the JB zip file, and let it flash that way. Unfortunately, I still received the same error message regarding the sticky bit factory_fastboot.

cellzealot, thank you for the link. I've downloaded the file that you linked to. Could you be so kind as to now give me a step-by-step on how to re-attempt the flashing process?
Quick update - I was able to get root back, installed safestrap, and flashed the nandroid that I had made back when I first flashed Eclipse. However, I am still having the same issue:
Whenever I restart the phone, I get the sticky bit factory_fastboot error. If I use the command fastboot continue, the phone boots up as normal; however, it would be great to not have to do this each and every time I reboot the phone. Any help would be greatly appreciated. Thanks!
More updates (still not fixed):
After getting root, I reflashed my nandroid, factory reset (both within the OS and in recovery), and then tried flashing both the ICS and JB stock ROMs. I tried flashing both using mfastboot, as well RSD Lite. The files flash successfully; however, whenever I restart the phone, I continue to get the stick bit factory_fastboot error.
Also, when I get into recovery, I try to flash via "update from external SD". When I do so, recovery simply restarts without flashing the stock ROM.
Here's my last update as to this issue:
After trying all of the methods that I could think of (RSD Lite, flashing via fastboot and mfastboot, flashing from external), the problem did not correct itself.
I brought my phone into a Verizon store, where they told me that they had never seen that problem before. They agreed to replace my phone pursuant to the one-year warranty (I received my phone in December), which I received today. I've again rooted my phone, but have opted to not screw around w/ safestrap and custom ROMs this time around, as I find the stock JB experience to actually be quite good.
Found the soultion!!!!!!
Ok guys so after serching a while I found out similar moto phones have the same issue. I found in a latin forum and in a Droid forum people ponting to the same issue. So the solution that worked for my Razr HD xt925 was:
1) Enter fastboot mode in your phone (very easy since every time you restart the phone you end there anyways)
2) Write this command on the computer: fastboot oem fb_mode_clear
there will be a dialogue with the time take and OK
You are done!
Thought someone might find it useful
Thank you!

I cannot get my phone to accept ADB commands while in the Bootloader. The phone has been doing some strange stuff so I decided to start from scratch and reinstall everything. I tried to use the "Restore to Stock Tool" but once it reboots to the bootloader, I get "device not found" until it gets to the erase commands, phone restarts and is wiped but still on the 6.0 update. I tried "adb devices" and the device shows up but if I try "adb reboot bootloader" it reboots to the bootloader but "adb devices" doesn't see the device anymore. The only thing I can think that could cause this is a corrupt bootloader but how can you correct the problem if you can't flash anything? If someone can suggest anything I can try, I would appreciate it.
6.0 is the current update...
Flash twrp then try flashing a custom ROM. Honestly it sounds like you might be doing something wrong, or maybe a bad USB cable? Keep trying I don't think you're screwed

Frankly, I would be surprised if your "SCREWED"... it sounds more like your misinformed.
ADB will NEVER work in the bootloader, it isn't intended to, that is what fastboot is for. ADB stands for Android Debugging Bridge because it is the computer's "bridge" to Android, you can think of it as the connection to the operating system, meaning the phone must be booted and running Android for it to work or there is nothing to "bridge" to.
Fastboot is a more limited tool designed to talk to the bootloader and get the phone so that operating system can boot or it can be returned to it's factory state, fastboot cannot talk or "bridge" to Android. They are different and unique tools with different purposes that are used at different times.
This is another case of why one-click or scripting tools are not recommended... even if they work 90% of the time or more, there is still failure due to automation.
I would suggest grabbing the full factory firmware package and install it MANUALLY with the fastboot commands and you will likely be fine. Remember to give it time on the first boot, it can be 20 minutes or more before things look like they are progressing initially.

So I got the computer to recognize the phone. I reset everything back to stock 5.1.1. Once I had it reset, the Bluetooth would not turn on (which was one of my original problems). So I took all the OTAs to get back to 6.0. For some reason when It got to about the 3rd update, it wouldn't complete. It failed but didn't specify a reason. I tried this 2 times without any luck. I left it at the update it was on and used it for a day. The Bluetooth still would not turn on and I was experiencing random data drops which required a reboot. I finally gave up because I was so frustrated. I figured something must be going wrong some hardware inside the phone.

Also, I see many guides don't show flashing the Bluetooth firmware for some reason, so depending on the guide you used might be wrong, always look at the XML file in the image.

Pure. I figured if I start all the way over from the beginning it would work out. Like I said, even one of the OTA's failed. I tried flashing the BTFM.bin file but that didn't work either. I will try some other stuff when I get off work today.
So I tried starting from scratch again. I get a "validation failed" when I try to flash the gpt.bin file. Everything else worked. Bluetooth and data are working now. Could I have a corrupt partition that is causing the validation to fail? Does anyone know the partition sizes for the Pure?

No, in fact it is quite common to get that message with the partition information... Ignore it, if everything else went fine and you having no more problems, your good to go.
Hello all. I am about done with this phone. Let me give you a quick timeline.
I had a bootloader error, so I flashed the NPN25.137-35 images to get it working
I used it for about 1 week, installing all of the OTA security updates
One morning, my phone had restarted (I know because "You must enter your pattern after a restart")
Over the course of this day, google apps starting force closing and opening some of them would soft reboot the phone.
The next day, random apps were doing it too
Finally, after one crash, the OS never came back up, it was bootlooping
Upon a hard restart, the phone only boots into bootloader.
This is where I am now. I have downloaded NPN...35-5, NPNS...93-10, and NPNS...92.14. Unfortunately, trying to flash any of these give me a "prevaildation failed security update downgrade" error on every partition I try to flash. The phone just bootloops when I try to restart it.
Things I have tried:
Using fastboot to manually install one of the 3 packages mentioned above.
Using a toolkit to automate the install of the 3 packages.
Using Motorola Device Manager (Never got it to launch)
Flashing the blankflash bin (No usable image file found)
Android OEM unlock setting was not set before this crash, so I cannot unlock the bootloader.
Praying to various deities.
Unzipping the packages, editing the *info.txt file into androidinfo.txt and rezipping to use as an update package (Invalid info.txt error)
I have no idea what to do next. I find it frustrating that Motorola doesn't differentiate between 32GB, 64GB, Amazon ads, no amazon ads, US, EU, or indian variant in it's model numbers! Everything is just "XT1687" and none of the update files are named with words, so knowing what the hell I'm flashing is impossible.
So, frustrations aside, does anyone have any suggestions as to how I can get this phone working again. On a side note, the only thing that I can think of that would cause such a cascading failure from Stock OS is RAM or Storage corruption / failing. Any thoughts on that as well?
=~=~=~=~= SOLUTION FOUND =~=~=~=~=
This may not be a good solution for anyone else that has this issue, but recently Oreo came out and the OTA update was captured. I was able to flash the new OTA because it had a higher security level and at least got the phone bootable.
Do you know what software channel you were on? E.g. retus, retla, etc? If your phone was completely up to date with the OTA, then you can't use a firmware version of less than 92-14 or 93-14. Whether or not you use 92 or 93 depends on the channel.
Locked bootloader limits other possibilities unfortunately.
Retus. I can't guarantee it, but that looks familiar to me, like I had seen it somewhere in the "about phone" section. Is there a released Stock image that has the current security patch? I can't find it on XDA and I'm not trusting androidfixfiles.info or a link in a youtube video.
93-14 hasn't been leaked yet. So you'll be stuck for now.

As a last resort you might try booting TWRP in fastboot mode, download and flash the TWRP flashable version of NPNS25.137-93-14. and see if that gets you back to a working phone. Just a suggestion. I don't know if it will boot when the bootloader is locked but it is worth a try.

I get that. What I am suggesting is not installing TWRP, but booting it from fastboot, if it is even possible. Given your results trying to flash a ROM I would say not. But what do you have to lose by trying?

I've tried that with a locked bootloader myself, it doesn't allow a non-signed image to boot. OP should give it a go as a 'hail Mary' attempt, but I wouldn't be holding my breath.
I've never heard of a phone that was fully stock with no mods or flashing ever done on it getting a bootloader error. The only bootloader error I am aware of is when the bootloader and ROM build are mismatched which doesn't happen unless the phone is being manually flashed. Was the phone on a custom ROM and you tried to return to full stock? Did you purchase the phone used?
If no to both exactly what did you see when you got the bootloader error? What was the message and what was the phone doing?
People who are on full stock with a locked bootloader don't usually flash system images so your story is a little hard for me to understand unless there is more to it. Normally a factory reset would be the logical solution when your phone is acting odd--flashing a system image seems pretty extreme and it sounds like flashing the wrong system image might be the cause of your current problems.

I agree. :good:
While my phone was wholly stock, I am not new to phone rooting or custom ROMS. I bought the phone from someone who was trying to unlock it. They screwed something up and couldn't get the phone to boot. I bought it, flashed the NPN25.137-35 image after reading plenty of XDA posts about it. This one was the Retus / North America stock image. Flashed using the suggested guidelines that are along the lines of "fb_oem_mode ... flash oem oem.bin ... flash partition sparsechunk1.img" (Something like that). That got it running and once booted, it had many OTAs update in quick succession. After about a week the phone started having trouble. Google apps would crash frequently, then non-google apps started crashing and restarting my phone. After one said restart, the phone would only bootloop. I tried rebooting into recovery to do a factory reset and got the bootloader instead. I can go take a look at the bootloader and see if it says it's secure / oem or what

Try flashing just the stock recovery, as it sounds like that is corrupt. Ideally you'd want to get a recovery that was the same build as you were on after all the OTAs had installed. At least you'd hope that that would give you the factory reset option.
If that doesn't work, there's fastboot commands to erase user data, cache, which would be pretty much what a factory reset would do. Hope you had your data backed up.
Oreo OTA came out recently. Someone grabbed the update file and uploaded it. I was able to flash it and get the phone to boot. The verdict is still out on if it'll be stable.
Problem is in the title. Here are the Cliff's Notes:
1) got Moto E4 from Textnow
2) fastboot boot TWRP.img (cant recall which image I used but pretty sure it was proper. if this makes a difference I can dig out the TWRP I used and attach it, but I really cannot recall which one it was. Pretty sure I got it from xda though, not the official TWRP page)
3) took TWRP backup of bone-stock device.
4) unlock bootloader at Motorola.com
5) check out the custom roms and found out about the LTE problem. Seanstars fix didnt work for me on several roms, but in his defense I may have done something wrong. I didnt want to mess with it anymore and decided to go back to stock.
6) I found out that I lost my bone-stock-TWRP backup through my own idiocy. I honestly have no idea how I got back to stock but I managed it. Seems to be awful hard to get a stock rom to work with. I must not be looking hard enough but it seems like all the links for Perry stock roms here are dead.
Now to the problem.... after all that I cant get OTA updates. I get notifications, the update downloads,, but no joy.
Device does *not* restart after the update downloads.
Manual restart begins the update process, but then I get the Android on the Operating Table screen. I relocked the bootloader thinking that might be the issue, but now I fear that there is some sort of signature verification issue that is stopping the update.
Trying to give relevant info from the bootloader:
Baseband: M8920_15000.280.06.58.02R PERRY_NA_CA_CUST
Product/Variant: perry XT1766 16GB P3B
I really dont know where to go from here though. Any help is appreciated, thanks in advance.

A number of partitions need to be pure stock for OTAs to work on Moto devices - including many that are not normally mounted. Likely one or more was altered by previous tinkering. Obviously system (never mounted r/w) and recovery; data must not have had dm-verity disabled. Etc, etc.
