[Q] Fastboot Reason: Sticky bit factory_fastboot?

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.
Here's a good tutorial on ADB commands. http://mobile.tutsplus.com/tutorials/android/android-adb-quick-guide/

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!

Awesome trick

flash write failure

Dear guys,
due to problems within this morning, i restarted my phone to wipe dalvik/cache.
But it occured that TWRP somehowe needs to have a password (which i didn't ever set though).
Didn't boot up at all now. Even with toolkit no chance to do anything with the device.
Any further suggestions/ideas?

Try flashing the factory image without using a tool kit. Google nexus 4 factory image. Download it to your pc and extract it. Run the flash-all.bat you'll find in there.

Some Partitions of the phone have got some bad blocks causing it to act in such a way !! Seems RMA(if available) is the best recourse since there is no definative solution to this problem !! You can try hard reboot as well as someone once pointed out that his n4 magically restored during it but others dint have that much of luck !! Also u could give LGNPST a try but since that also writes the partition it is highly unlikely to get you through !! One Solution I know will surely work is Qualcomm PST using the HighSpeed USB Device . But unfortunately we need an expert help, probably a Qualcomm employee to get in touch with since the tool has still not been cracked by anyone for n4 though I read somewhere that someone was able to restore using QPST !! Also mostly a JTAG Repair can help you but thats a rip off !! I'll anyday prefer a official LG/Google Repair over a JTAG !!
Hope you find my post useful !!

I was afraid of that. Try one thing. Relock the bootloader, fastboot oem lock, then re-boot and see if the bootloader locks. If it doesn't, and it probably won't, then rma is your option.
Edit, haha, I just read that thread you posted and they tried the same thing

i was already trying that. at first it seems that the bootloader got locked again but right after restart it is already unlocked again.
I guess RMA will cause problems due to the fact that it was a rooted Nexus, using a custom rom.

Google seems to have been pretty good with rma's when it's a hardware failure. Pretty sure your emmc is borked. But you never know until you send it in. Hopefully there won't be a problem.

Ok I'll give it a try on monday. But as far as i know, i'll need to call them first.
I could imagine that they'll try to let me wipe my data or give me any kind of instructions to see if they can resolve the problem right away? What do i tell them?
At latest when they'll lead me to the recovery i'll get stuck using TWRP at latest.
Any kind of conversation dialogue i can follow up?

Let's try one more thing, inside the factory image is a zip file, extract that. In there is recovery.img. Put that file in the same folder as fastboot.exe. In fastboot try fastboot flash recovery recovery.img
If it works it'll put the stock recovery on.

Nope, same issue " flash write failure"

It won't let you flash that either to the best of my knowledge !! Just don't tell those operators that you have unlocked your bootloader and have a custom recovery !! Basically they won't tell u to go into stock recovery !! They'll just ask you hard reset the phone using physical keys !! Bdw check my pm !!

Np, not sure what to tell them. It still boots I assume so you can't tell them it won't boot. I guess just the truth, it is a developer phone after all so it should be flashable

[Q] After 4 1/2 yrs on XDA I am finally stuck! Bricked No download mode, No OS.

Hello my fellow XDA Members. I am stuck in a tight spot and after reading and re-reading some things the situation doesn't look very promising. I hope this is the moment that Karma shows up and I can get some help on this. Here it goes.
Specs - LG G2 D801 Variant > TWRP V2.8.3.1 > NO OS Currently
I was running Cloudy G3 Rom smoothly and got bored and decided to flash that new rom that is a 5.0 Rom all variants. Did the usual back ups and flashed it. Something happened when I flashed the rom. It went through the Aroma installer and then said "successful" but stuck in a bootloop. I tried it again and nothing happened. Then I tried to wipe everything again and started getting an E: Cannot mount (data or system I forget which as that error went away after I completely formatted data, wiped everything and reflashed Cloudy Stock. )
> Cloudy stock bootlooped and nothing is happening in TWRP. I Am using the USB OTG method of getting files on the phone and getting it charged but anytime I try to do anything (flash a rom, an older version of TWRP) it just immediately restarts TWRP and thats that. I have No OS at all.
> I tried to use one of the methods to get into download mode and flash a stock KDZ but the phone acts like it is going into DL mode (shows the little blue transition screen) but never gets into the ACTUAL download mode where the PC or flash tool can recognize it.
So in a nutshell > No OS > I can get into TWRP but it does nothing > No Download Mode > Don't want a new phone > Don't want to take it apart and try to short circuit anything if possible. LOL.
I am totally stuck here. I am done alot of work and even helped friends and family out with their devices over the years. I am just not sure if I need to consider it a done deal and get a new phone or maybe one of you guys know of something easy and obvious (please let it be the latter) I am missing. Thanks for any help you can offer. I Will be standing by.

I haven't thought about flashing a bootloader. How would I flash the bootloader if I can not the phone into either DL mode and or TWRP doesn't do anything either? Is a bootloader file just a flashable file like any other .zip file?

The first one I can not do as I do not have any knowledge at all of Ubuntu, Linux, or any of that. It would take forever to get a working knowledge of that software in order to get things going again. I would probably just have to either take it to a cellphone repair shop or get another phone before I could do the first link.
I have not tried the second one but it is a viable option. I was looking at it online and trying to talk myself down from having to do that. I would reallllllllly rather not have to take my phone apart if I can keep from so that's kind of what this post is all about. Just trying to see if anyone knows of ANYTHING else before I go taking apart my phone.

Can you describe more about "twrp doesnt do anything"?
Does twrp boot up?
Can u see/wipe partitions?
Can u install any rom in twrp? Does it finish?

TWRP boots and I can go into wipe, advanced wipe, and format data and it says it's successful. I can use file manager and move items back and forth from USB OTG. If I try to flash anything it just reboots TWRP immediately so I can't install any .zip files at all.

My guess is that your bootloader is damaged.
The only option i can see for you is that Ubuntu thing i shared with you. So, lets stop acting lazy and do what needs to be done. Dont scare since there is nothing to loose. LG G2 is unbrikable
Booting up ubuntu or any other linux os is so easy. And there is nothing much to learn. Trust me.
Go to ubuntu website and download their newest iso file. Burn it on dvd and boot it up. You dont have to install it, just choose "live mode" and it boots up. Just like that. Then yiu can proceed with tutorial mentioned above and it shouldnt take more than an hour from you. Its all typing some commands in terminal (remember CMD in windows!).
Just make sure to download the files mentioned in that tutorial before proceeding.

First of all calling people lazy is not nice. I'm not lazy I am trying to play it safe. I wouldn't want to brick it to the point to where I don't even have recovery and it can not even be charged any longer. I have Ubuntu on my desktop upstairs. I have used it a little. It's not that I am completely ignorant to Ubuntu I am just a total novice. Also the issue described in that post doesn't exactly match my situation. I am not in a black screen. It's more like a bootloop that I can not get out of because TWRP is not doing what it needs to do and I can not flash TWRP a ROM or get into DL mode at all. Also that post says,
"VERY IMPORTANT!!!!!!! You must use the img files that correspond to the ROM you have installed before getting the problem to avoid breaking your phone."
I don't have a rom on my phone soooo...

You didn't answer my question well. If on TWRP you can finish installing rom without any error, and you keep coming to twrp after restarts, that's another situation. Try this:
http://forum.xda-developers.com/showthread.php?t=2451696
But if you cant even finish install in twrp (twrp gives you errors or just restarts before giving you "successful", either you have problem in rom you try to flash or you need to build everything up from start.
That lazy thing was for encouraging you to do it.
And you cant brick your device. There is always a way on G2.
For img files: find them from last stock rom that was working on your phone.

Axon 7 brick

I've spent the whole night trying to figure this out, but to no avail. Here goes...
Hey guys, so I was innocently playing around with GravityBox when I restarted my phone so some new settings would kick in, and it sends me into a bootloop. I went into TWRP Recovery, and at first factory reset my phone, hoping it would solve the problem, but it didn't, so I ended up "Formatting Data", which still didn't work. I'm kind of new to this whole flashing/rooting/ business, and I was wondering how I could fix my phone. If turned on, it stays in the booting process with the golden "Axon" letters forever. The model is the US variant, it's bootloader is unlocked via the ZTE Request Form, and it currently has TWRP as it's custom recovery. Help will be much appreciated. Also, it's on OTA B20
Edit: Alright so I've tried to flash to boot.img as well as recovery.img in twrp, but both give me an error. Strangely enough, if I wait out the Axon logo for about 5 minutes, it actually boots up, but as if it was the first time turning it on (asks you to sign in to google, wi-fi setup, fingerpring setup, etc). Another thing I noticed was that it says I only have 4gb of storage, instead of the 64 it originally came with. Every time I reset it/turn it off, it makes me set up the phone again.
Edit #2: Fixed with the help of this thread http://forum.xda-developers.com/axon-7/how-to/how-to-restore-a2017u-to-functional-t3445895 Only problem seems to be that Wi-Fi does not work. /:

I'm in the process of doing this as of right now, thank you. Will update.

It sounds like you're going to restore to stock, so perhaps this won't help at this point, but Xposed has a "safe mode" which can be activated during boot-up and perhaps help to resolve these sorts of issues...here's a thread about it:

This once saved me when I had a boot-loop issue with a tablet a while back. Good luck!

Same boat. last day or so of newegg 14 day return. At this point my decision is between Return or Replace. No ZTE image or flashable modem file means there is no fix for this, as far as I can tell.
FYI,. I have tried all of the possible fixes offered.

WiFi not working is a mismatch between boot.img and /system, they have to be from the same 'set' so if you flash B20_Boot (BL unlock) boot.img, you have to flash a matching /system as well. We have a problem with numerous file version marked just B20 floating around. From what i know, this

is for sure the B20_Boot /system image , but i am unsure of anyone posting matching boot.img file. The one on idlekernel might be correct, since the dump came from B20_Boot BL unlocked phone, but it might have been modded. Maybe someone can post one

Uggg... I'm really frustrated now, because I got it working with tenfar's original modified boot image and rczrider's system backup. Everything was working. Of course, I didn't have root, so like and idiot, I tried to flash SuperSU 2.76. The phone stuck at the LTE screen after that. I tried re-following all my past steps, and can get the phone to boot, but it's acting crazy. I have two empty SIM icons on the taskbar (I had none when it was working fine) and the phone is very jerky and laggy. I cannot shut it down, or connect to PC easily. It will frequently reboot on its own, and I can't even power it down (it'll say "shutting down" for a few minutes, then reboot).
I eventually got it to shutdown, and repeated the "How to reset..." steps, but it's still acting crazy. I've wiped everything except for system. I'm going to try that next.

Would not mind fixing this rather than shipping my packed up axon7 to newegg. Think I have a few days before it has to ship, so I am open to working on it some more.
Thanks.

It kinda late right now but if that is what's needed I'll be uploading my boot
Image tomorrow (b20_boot),
P. S. I know for sure CM13 is just around the corner and that alone is fix for slot of you guys boot problems .

That's the thing.... I've restored it repeatedly. All traces of 2.67 should be gone. I've completely restored it three times now.
I'm honestly thinking I'm better off returning this phone while it's still working. I wonder if something is wrong with it.

Moto E4 sperry XT1766 not booting up after a restore via TWRP

Long story short, my phone only displays the n/a screen and won't boot up.
I got the phone from Sprint, and it is the Qualcomm version. (The box says that anyway.) I wanted to root the device, so I unlocked the bootloader and attempted to flash SuperSU. This didn't work, as the app didn't show after the flash. I then tried to use Magisk, but I received Error 1 (boot image patched by other programs). To fix this issue, I downloaded a similar stock ROM and tried to install that. I ended up just wiping all the data on the phone, including the OS. Luckily I did make a nandroid backup.
The phone currently has no OS, due to me wiping all my data on it. I made a backup of when it did work (said earlier), with all partitions excluding Data. I have restored it, but it doesn't boot up. TWRP says nothing about there being no OS on the phone. I can't find a stock ROM of this particular phone, but there are some close ones. (sperry XT1768 I believe.) If anyone could help me restore my phone or possibly provide me the stock ROM I would be beyond grateful. I would also be also be okay with posting any logs or things you need.
Thanks much!

Go here:
https://firmware.center/firmware/Motorola/Moto E4/Stock/
This is the Boost XT1766 firmware :
https://firmware.center/firmware/Mo...ubsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip

I did a dumb and was rewarded
So, I ended up flashing the sperry XT1768 ROM that I had downloaded. Keep in mind I already lacked an OS, so I had nothing to lose.
PLEASE NEVER FLASH A ROM THAT DOESN'T BELONG TO YOUR DEVICE. THIS COULD CAUSE YOUR PHONE TO BE BRICKED.
Against the above statement, I literally had nothing to lose. I got my phone to boot up, and it has all of its functionality. Thank you for posting the correct software amarc78, I'll have to flash the correct ROM at a later time.
Moral of the story, please know what you are doing before you do something dumb. Use proper forums (such as the one you are on...) to do such tasks as rooting your phone.

Hmmmm, sounds intriguing. I soft bricked my xt1766 a few days ago and have found multiple fixes, but nothing that sticks. That above firmware? Took me two days to realize I needed RSD Lite to flash it. What was that RSD Lite? You play funny with Windows 10, no worries, I'll create my own batch file to manually flash this firmware.........WHAT!!!!!!! Why is there a multi colored ring saying "erasing" at the bottom and rebooting every 30 seconds?????? So after further research and "multiple error 7s" as well as "cant mount cache/data" errors, I came to another fix, lo and behold, im in a TWRP bootloop. Long story short, FML!!!!! Im glad you found a fix. Happy flashing.

I used this rsdlite, and it works on my PC with Windows 10. Just make sure you have Motorola drivers installed.

For the Twrp loop, try selecting reboot bootloader, then in bootloader, select start. That should get you into system.
There is a fix for that, I'll find the link. Some twrp build aren't wiping something properly and causes a recovery loop after formatting data.

You're just all over the place, kudos to your dedication.
Basically in trying to fix the bad key/erasing boot loop I flashed twrp and tried to format data/unencrpyt which in turn throws errors which require manually reformatting /data until errors are gone and then formatting/unencrypting again which upon rebooting turns into twrp loop. Then tried to flash no-verity, the twrp loop persists.

Used to have a couple of these phones .
If you're stuck in a TWRP loop
The quick workaround is to reboot to bootloader, then proceed from there to Start. However, you'll need to do this *every* time until the BCB is cleared.
To clear the BCB manually, issue this command in TWRP terminal:
Code:
dd if=/dev/zero of=/dev/block/bootdevice/by-name/misc bs=1M
have you tried formatting data, then flashing.magisk?
