[Q] Stuck in lockscreen!

Hi,
Big fail by me, I ****ed up my lockscreen by disabling all the unlocking methods. Now I'm stuck in the lockscreen and I have no way of enabling them again. I don't have a PW on it, I just don't have any way to unlock it.
Is there anything I can do? I don't want to lose all data!
I've rooted and flashed CM7.2
Thanks for reading.

your probably going to lose some data pal. one thing to try first. turn the phone off and on again, while its turning on play with the screen to keep it active, you might be able to keep it unlocked until it loads, then try getting into settings. if not boot into recovery and nandroid backup! the try to reflash cyanogenmod over what you have. dont delete anything just flash over. if that doesnt work then your going to have to clean install mate. sorry :/

After 4.3 update, phone reboots whenever i log in

The phone received the OTA update this afternoon. After it was updated, every time I try to swipe in at the lock screen, the phone reboots. Based on the lock screen, I can see the phone works just fine. There's notifications, I can scroll to the lock screen widgets and I can even answer phone calls.
The phone was stock/rooted prior to the update. What to do?

Same. Update seems to have finished, bootloops after inputting user password to unlock screen. It's a short boot right back to the password screen again.
Was stock, rooted, unlocked, 4.3 was OTA update

I was having miscellaneous issues after the 4.3 update as well. I'm starting to think that some of these people who insist on un-rooting your phone prior to system updates might have made a good point. I don't use a lock screen, but I couldn't uninstall any applications or the phone would reboot. Even trying to modify some of the settings would force reboot as well.
I ended up giving up on it and wiping it / flashing 4.3 stock. If anyone is reading this and hasn't updated to 4.3 yet, I would suggest unrooting your phone, but keeping an unlocked bootloader before updating (the update will break root anyway... and OTA Rootkeeper doesn't work). To get root back use TWRP to load SuperSU and you should be back in business.

I got really lucky somehow, in getting the phone to work and managing to keep my data.
I don't remember every step in order, as I'm sure lots of them didn't do anything, but eventually I just reflashed every part of the factory images EXCEPT userdata.img as I (correctly?) figured that would erase my ****.
Wiped cache a few times from recovery as well.
Had a couple scares - at one point the LED turned RED during a couple bootup attempts.
First time after the 3rd round of flashing (including system.img) it would not boost past the X. Had to wipe cache in recovery again.

[Q] Where to go from MJE?

Have MJE and had stopped OTAs. Would like to move forward to lollipop on this phone. 2 different questions:
1. Would I be able to install a lollipop ROM from MJE or is it already locked down with no options
2. Phone is in "custom" mode. Can I just reenable OTA updates and let it receive updates OTA without bricking or does the knox need reset first? Not worried about warranty issues.
Please spare the flames, I dont know what I am doing much but can follow instructions and I am just looking for a little help. Dont want to blow my phone out and not be able to do anything with it. Thanks!

Im in the same boat with you. Im still on 4.3/MJE/Stock/Rooted. I rooted with RootMaster when i got the phone over a year ago and disabled OTA updates. Its been an awesome phone but recently been having glitches (screen flickers randomly when on and auto adjust brightness is turned off and google maps cannot find my location, the GPS icon never comes on anymore, other mapping apps still work fine) and ive had to disable my google play services from killing my battery. Also my music has been stuttering on poweramp (not sure if it is just a app issue). Another thing Ive noticed is when i restart my phone its been doing a double bootloop, it gets to the launcher screen then immediatly reboots, but then fully boots up the second time.
Any suggestions anyone? I want to keep root and dont mind stock. Go launcher gives me most of the customization i need, really only need root for AdAway (which doesnt work so well anymore), Gemini App Manager- so i can keep certain apps from startup upon boot, SD speed increase (which im not really sure actually does anything), and of coarse TITANIUM.
Do i need to do an ODIN flash or TWRP or CWM? Can i just hit the factory reset and keep my root? Maybe flash up to 4.4.2? I keep seeing that 4.4.4 and higher cant be rooted unless im mistaken.
Any direction from someone knowledgeable would be greatly appreciated.

Is my XT1575 recoverable?

My XT1575 just decided to go into a bootloop a week ago on its own, literally. I was just checking traffic on Google maps when I noticed it started to lock up. Finally, I see the Motorola splash screen, and that was the beginning of it. Went into recovery mode and tried a factory reset, clear cache partition, etc. but no luck. I've tried everything under Android 6.0 here but it continues to bootloop no matter what I do.
It's not rooted and the bootloader is locked, so I don't think I can even install TWRP or any custom recovery. I have never even though of enabling USB debugging so that's out of the question. What's odd is after trying all sorts of things, sometimes, after the phone has been off for a while I would power it on and it would actually boot into the Welcome screen. Shortly after that though, it locks up and starts bootlooping again. I don't know what else I can do about this or if it's recoverable. I hope someone can help. If it's of any significance, when in recovery mode, at the top I see what I think is the firmware it's currently on -- motorola/clark_retus/clark 6.0/MPHS24.49-18-4/5. Please help!

Update - After having my XT1575 powered off overnight, I powered it on this morning and it was able boot all the way into the Welcome screen, setup, etc. Right away I went and turned on USB Debugging and Allow OEM unlock. Tried rebooting and again it fails to boot. What's weird is it randomly seems to boot when it wants, and something must be corrupt but I just don't know what it could be. Does anyone have any ideas?

Don't unlock the bootloader.
If it is locked and behaving that way you should be able to get a warranty fix out of Lenovorola. If you unlock the bootloader you void your warranty, and they might choose to not honor it even if you say the problem started before.
Painful and slow as it might be, I'd recommend working with the manufacturer on this one.

I'm afraid it's too late for the bootloader, since it was one of the things I was trying out of desperation. After trying fastboot flashing the stock firmwares, I still get bootloops and strangely enough I was able to use the phone the other day for several hours before it started bootlooping again Thing is, it seems to behave differently at random times. Sometimes it makes it all the way up to the "Android is upgrading" screen but then freezes and reboots.. Other times it locks up at the Motorola splash screen and reboots.. And sometimes it even boots all the way up, is usable for a little bit, then begins bootlooping on its own.
I'm just wondering if something is corrupt software-wise (boot? system? etc?) or if it's a hardware issue. How do I even tell at this point?

The random nature of what you're describing does sound like hardware. Consider a full restore where you fastboot flash everything back to stock of you haven't already.
Check logs. See if you're getting anything in last_kmsg. Use an app like syslog if you aren't used to pulling them, though you might have to use adb if you aren't getting through boot all the time.

Thanks for replying. I've tried fastboot flashing everything and even going into recovery and clearing cache partition as well as doing a factory data reset. I'm afraid it may very well be hardware. I'll try your suggestion about the logs.
Is 'last_kmsg' a line I should be looking for in the log? If so, what would I need to see in order to determine whether or not it's a hardware problem?

/proc/last_kmsg is a log file that should get written to if a kernel panic causes a reboot in theory. In practice I find it is often blank even after a random reboot.

going by that logic the thing that you should have done was get a factory image from moto and flash to stock using moto tools if that failed at fixing it then send into moto it might not be lost yet but the more you progress the more less likely to replace the phone moto is...
it sounds like something is going bad could be ram emmc or the soc
What i would do is get into discussions with lenovo to see if they can get you fixed up. if you unlocked the bl they know be straight with them. if you get nowhere and no rom you load can fix it sell as parts replace at your expense...

TWRP and LineageOS working fine. But I locked the bootloader after. Is this trouble?

After installing TWRP and LOS I unknowingly locked the bootloader.
I had the idea this was the course of action to protect your phone. Only after did I noticed messages saying not to lock it.
After that the phone automatically rebooted and TWRP apparently detected the problem and did something to fix things I suspect. It was too fast and I can't recall the details.
Anyway, everything works fine. Apart from the warning message during boot, that everyone also gets.
My question is:
Will this be a problem when upgrading TWRP or LOS? Or is there anything I should be worried about?
Thanks
