[SOLVED]stuck in bootloop help please - Samsung Galaxy Nexus

edit: I got it. I was stuck right after the unlock and could not get menu after going into the stock recovery. It appears that you have to push the power button just a fraction of a second before the Vol up/down. Or at least in my case that is what worked.
Trying to root this manually with an Ubuntu Linux box, adb and fastboot setup I got stuck. Not sure what is wrong. Any help is appreciated. This is what I did so far:
adb devices recognizes the phone
1- downloaded fastboot and cd to it in terminal (but don't really need it since it is already setup)
2- volume up and down and power to get to inital menu with locked state
3- fastboot oem unlock, chose yes and got the unlocked state
now I can't get to the menu for recovery to wipe data and factory reset. I pressed the volume down to get the recovery mode option and then power button, it flashed an android standing up (after the google and the lock screen) but quickly goes into the laying down android with a red triangle in it's tummy. Did I miss something?
phone won't boot up (bootloop). any help is appreciated

Fastboot Problems, because of hw keys

Hey
im trying to unlock my bootloader again (had to lock it because i did a OTA on unlocked stock firmware)
im currently on stock ics, if that has anything to say. but the problem is when trying to install the fastboot drivers in windows device management
as far as i have read, when going into fastboot, is powering of the device, press and hold the menu button and connect the usb cable to the phone then u will get a blue light, find the drivers and install
but my menu button does not work anymore, idk why but it wont work when running android either. i have also tried getting in fastboot mode by holding the back button, then i get a green light as usual.
is there any way to enter fastboot without holding the menu button, or do i need to order a new keypad board for my phone
Thanks, Joakim
EDIT!!!!: i dont know what i have been thinking about, as you could enter fastboot, by typing adb reboot bootloader in adb, sorry
good you found out... there's also an option in flashtool inside fastboot window called "reset to fastboot through ADB"... also works... obviously your phone but be turned on and connected to PC through ADB.

[Q] Bricked! Stuck on Google logo, can enter Fastboot mode, but unrecognized by comp

Truly happened out of nowhere. I was running the Lollipop developers build (LP***9?) and right around the time the OTA was supposed to happen, my device bricked.
My device was rooted, bootloader unlocked. When attempting to boot normally, it is stuck on the Google logo. I can enter Fastboot mode by pressing Power + Vol Down, though the device never seems to be recognized by my computer (checked w/ adb devices command), so the Nexus Tool Rootkit is seemingly useless. When attempting to enter recovery, the Android robot is shown with an exclamation point. I really can't figure out where to go from here, and it's ultra frustrating because I feel like this happened on its own!
Any ideas?

If you're in the bootloader you need to use "fastboot devices" not "adb devices". Also, in recovery from the "dead android" hold the power button and tap VOL UP once to get the recovery options for factory reset, etc.
I have just got the same problem. I'm stuck at google logo, can't do much more except power + vol down
oh, this works perfectly well.

[SOLVED] Can not unlock the phone (lockscreen) & can not enter into fastboot mode

Hello.
This could be more general question so I try to get an answer here. Device: H815 wit bootloader unlocked. USB debugging is enabled but PC is not authorized so I can not execute any ADB command.
My problem is simple, I have flashed the latest Genisys rom and after initial setup (included lockscreen pattern setup) I restarted the phone. No I am not able to unlock the phone with correct lockscreen pattern provided. When I "connect" three dots it says "Try again", when I connect four and more dots it stucks and I can not swipe another pattern.
I am also unable to enter into recovery/fastboot mode (with power+vol down buttons). The phone starts booting instead of boot into the fastboot mode.
Is there any way how to flash anything or delete files containing lockscreen pattern?
Thank you very much for any help.
Babi
EDIT: Solved with LGUP.
when you attempted to go into recovery by holding power + vol down, did you let go of the power button and hold again immediately (while keeping vol down hold) when LG logo showed up?
anyways, if you can get ADP to detect your device, you can use this command to remove lockscreens
rm /data/system/locksettings.db
rm /data/system/*.key
or if you able to get into TWRP, find that folder and delete those files manually.
sorry i'm at work and can't type long, but let us(community) know.
Yes I did. I tried it with volume down button released as well. So I am not able to enter into fastboot mode. This issues persists.
I know about these commands, but how can I execute these commands without authorized device (ADB litsts "unauthorized" device)?
No, I was also not able to enter into recovery mode.

Soft-brick problem

I restored an lineage os update last night, then i restored a BOOT update that didnt belong to that rom and i`m in bootloop unable to enter recovery or enter bootload, my phone responds only to power button+ volume up ( it restarts), tried to connect fastboot and i get that device isnt found( its connected to usb ports, i installed htc sync manager for htc drivers)
What can i do to go into bootloader, because if i get there i flash twrp then restore the correct rom, but now its just bootloops in RR remix( it doesnt restart itself just loading loading )
Can i get some help with right drivers or something that i could use that command" adb reboot bootloader" and it wont answer with device not found
P.S I get the device in device manager but in adb just says "device not found"
P.S2 Close the thread, i let the phone fully discharge then Volume down + power and it entered fastboot and i was able to get to recovery, nvm

I know you fixed the problem, but for future reference, in the above scenario, as long as you can force a reboot (power+vol up); the moment the screen goes black to reboot, just slide your finger to vol down (no need to hold power button any longer) and keep holding it; and the phone will go to bootloader.

adb would never have worked in the condition your phone was in. The phone needs to be booted to OS or custom recovery for adb to work.

Rooted G7 Play: Forgot pattern lock, can't factory reset either

I searched and didn't see anything that relates to my specific problem.
I have a 1952-4 that I rooted per instructions on here (Magisk). I dropped it and broke the screen about 9 months ago and just fixed it today...and I can't remember my pattern. I'm up to 50 tries, so now I have to wait 120 seconds before it lets me try the next one.
Since the root process requires you to reboot recovery for root, doing that just sends it to the normal lock screen. When I hit Vol Down/Power, my options on the bootloader screen are:
-Start
-Restart Bootloader
-Recovery Mode (restarts it, sends to lockscreen)
-Power Off
-Factory Mode (restarts, sends to lockscreen)
-Barcodes
-BP Tools (restarts, back to lockscreen)
-QCOM (restarts, back to lockscreen)
-Bootloader Logs
-Switch Tools Mode (enables/disables "Tool Mode Config" option on the bootloader screen)
My computer beeps the "something USB has been plugged in" chime when I connect it, but it doesn't pull up in File Explorer (unless it's off, but just shows that a USB drive has been connected but won't pull up anything when I click on it), nor can I connect through ADB. It's not a cable/USB port issue either as ADB finds my Note 8 when I plug it in and check via "adb devices."
Can't wipe it via Find my Phone either because it's been 270 days since my account pinged the phone, so it just shows up as "Android" device.
Any suggestions on how to either get my computer/ADB to recognize it (with root) so I can just delete the lock database, or how I can factory reset it? Am I forgetting a reboot option?
Thanks in advance.

Window 10?
Yeah. It should remember this phone, since I used this computer to root it when I first got it a year and a half ago.
I used a different cable and got it to pick up the phone (as an unknown device) in Windows but NOT ADB, and the phone to realize it was connected (see last line on phone screen) but they're not talking.
If I boot it all the way up, either regular or recovery (root), it doesn't show at all on my computer.
Like I said, I'd be fine with wiping it, but can't even get to that option.
Install the moto drivers. If that doesn't work then make sure your using a usb2 port and not a usb3 port as its a known issue with moto phones.
I just ordered a new OEM cable.
Also ordered an OTG cable to see if I can force it to startup into a different mode that'll allow me to do something with it.
I'll update this thread once I'm able to test them out.
I got a new cable. My USB ports are not labeled, and my Moto drivers reinstalled.
After rebooting to the recovery screen, I plugged it in and apparently I have fastboot. I checked the bootloader logs and it says:
AP Fastboot Flash Mode (Secure)
Fastboot Reason: Volume down key pressed
USB connected
Windows doesn't pick up anything connected by USB. I can't restart to get root because then adb doesn't pick up the phone either because of the screenlock preventing me from hitting ok to trust my computer.
I'm asking the following because I can't find answers: Can you delete the screen lock file with the only bridge being fastboot, not adb. How can I do a factory reset if rebooting to recovery is our normal way of turnin gon the device with root access? Or would reflashing something work?
command line commands are a perishable skill and it's been a couple years since I did this stuff.
Thanks in advance.
To recap, I either need to be able to get into the directory to delete the pattern lock, or factory reset the phone.
I've tried the pattern lock 79 times, which means I have to wait 300+ seconds between tries. I think an error is causing that though.
Fastboot is my only option at this point as far as using commands goes. Rebooting recovery just reboots it with root permissions, but neither adb or Windows 10 picks it up. Using a brand new factory cord and tried every USB port on my computer, even the USB-C to USB-C. But I can't find anywhere that shows how to get into the directory using fastboot.
In Device Manager, I've been getting an error with Android ADB Interface (The device cannot start; Code 10). I uninstalled, reinstalled various drivers, killed adb.exe, etc., Still happening.
HOWEVER, Motorola ADB Interface is working just fine and goes away when I unplug my phone, returns when I plug it in. Only when it's in recovery/fastboot mode though.
I got into Safe Mode, but computer won't pick it up.
I can't get into Field Test Mode. I did reboot it into something else. I don't know what, but the screen was off and the home button was illuminated. EDL mode? I don't know. Neither my computer or adb read that anything was attached, and i can't figure out how I did it.
I also tried sideloading some pattern lock removers, but apparently you can't do that in fastboot.
Thoughts?
Just to close this out with a solution: I had forgotten that in order to get to the recovery menu, you have to hold the buttons when you reboot recovery. Didn't realize that until I was rooting my Moto e6.
Factory reset complete. No more pattern lock. Though since I've now tried rooting it 4 times with 4 different images and have not succeeded even though I had root before all this, I wish I could have realized the above and possibly gotten in and deleted the gesture.
Lesson learned.
Hold what buttons? I'm afraid I'm in same spot.

Just found this. Timing is everything apparently.
Press and hold the Volume Down and Power buttons simultaneously until the Android Recovery screen appears.
Press the Volume Down button to navigate to Recovery.
With Recovery displayed, press the Power button.
When you see the 'Droid' with 'No Command,' hold Power and tap Volume Up just once and immediately release both buttons.
Scroll to wipe data/factory reset by pressing the Volume Down button
Press the Power button.
Scroll to YES by pressing the Volume Down button.
Press the Power button.
The 'phone will wipe all contents.
Press the Power button.
The 'phone will now reboot to the initial setup screen.
