[Solved] 5.1.1 OTA and stuck in bootloop cant access fastboot - Nexus 9 Q&A, Help & Troubleshooting

So I had the OTA update for 5.1.1 the other day and thought "yay, let's update." it worked fine till this evening where it crashed to a power off state and in now showing the Google logo like it's about to load up and then a turned off screen.
This repeats over and over I can't even stop this loop.
Holding the power button and it just continues to loop.
Power + ANY volume button and it will show the HBOOT or fastboot menu then before I can select anything turn to the powered off state and loop through (if I'm still holding the buttons the menu will show again shortly, or go back to the Google logo)
Any ideas for a solution?

try waiting until the battery drains all the way down then hold the volume down button and plug it in. if that doesn't work then all you can do is contact google support and they'll probably replace or fix it.

Hold the power button down for 20 seconds 3 times. It helped me once with a similar situation

So I have found a solution. Instead of deleting the thread I'll leave this here unless anyone else has this problem.
It seems that trying to enter the fastboot menu when plugged into a USB seemed to work.
It was either the fact it was in the computer, the timing I pressed the "power button + power down" combo, or it had just looped enough times and decided to actually stop interrupting me using the fastboot menu.
Either way, I cleared the cache partition using the recovery and it booted up fine.
EDIT: Thanks for the help, I had tried holding the combo for a long period of time (multiple loops of the booting). I also feared letting it drain in case it refused to startup again and I would have no chance of fixing it.

glad you figured that out! android can be mysterious sometimes. especially when it's on the nexus 9.

Touchpad Froze? Heres a solution

I was in TWRP recovery flashing Xron rom b2.9 and the recovery said the zip file cant open. So it just kept doing its thing and would not let me go back to the main menu. I tried hitting home and back buttons, but no luck.
This was not found by me. I am giving credit to this amazing person who somehow found a trick to reboot the device even if your not in an OS.
"The reboot solution that I found to work all the time is to simultaneously hold the power button, volume down button and the big HP button for 30 seconds."

5th post- http://h30434.www3.hp.com/t5/Other-HP-Consumer-Products-and/How-to-reset-HP-Touchpad/td-p/852893
I had an issue with my Touchpad where the touchscreen stopped responding in CM7. Volume rocker worked and power button would turn the screen on and off, but I was stuck with no touchscreen and no means to reboot. After a mild panic attack, I plugged it into my computer and luckily had debug mode enabled so I was able to adb reboot it.
But this... this is incredibly useful. Thank you for the post. I'm glad to see that the manufacturers making devices without removable batteries are giving us a trump card to hard reset the devices. My 7" Galaxy Tab has a similar function where holding the power button down for long enough eventually resets the device.
..or you can just hold power + card button for 6 seconds. no volume button needed.

[Q] S3 keeps restart itself

i got s3, suddenly it started to reboot itself all the time, what i see is only the samsung logo and then black, and samsung again.
the funny thing is that when i put the battery in, it automaticly start with this loop.
during the loop, when i press home+volume up, i can see the cwm screen for two seconds, and then it reboot again.
if i press home+voulume down, i see the warning in the stock recovery, but when i press volume up, nothing changed, and eventually after two seconds it reboots again.
i tried to connect it to my pc, but it dosen't show it in device manager, and have no indication that i connected it.
also, when i connect it the charger, i see circle, and then a battery for a brief second, and then the circle again.
is it simple hardware problem (stuck power button? even though it seem okay, but it may explain the automatic turn on), or half SDS?
anyway, are there any recommondations? i have'nt flashed it recently or anything like it.

as i wrote before, i can enter to both recovery modes (volume up or volume down) for something like two seconds, i can't do anything in it.
if i try to get to download mode (home and volume down) i see the warning, but either i press volume up or down, it reset itself.

the regular, about flashing custom roms, if i want to continue press volume up, restart, volume down.
either way, it restarts.
any way it is the power button stuck in 1 mode?
If phone starts on battery insertion, before you push the button then yes, power button is shorted out.

Try leaving the battery out overnight/long time, it helped when I got my phone stuck in a bootloop. But that was due to oc/uv...did you try something risky, causing it to bootloop?
no, it was in regular use, nothing risky.
yesterday i dissassembled it and checked with multimeter, it seem that the power button shorting the circuit, so i ordered a new one, going to be a surgical operation...

[Q] Xperia Tablet S (SGPT1211) not responding to reset/boot comands

Hello,
I think I might be at the end of the road with my tablet. I've never rooted it or tampered with it in an way, however yesterday it locked up so I did the usual soft reset (hold power and vol+ for 10 seconds) I then turned it back on and the sony logo popped up, but there it just hung. If I press and hold the power button it switches off, a brief press on the power button brings it back on in the same state. So I go Googling, including looking at threads on this site, all seemed to advise to try to get the Android recovery menu up. on the Sony this is done by holding the power and vol+ and then releasing the power button (only) when the son logo appears (this process to be started when the tablet is off) so I did this, and no response at all. Worse than that, where it would turn on and instantly hang, it now doesn't turn on at all. Hooking it up to my PC I can see the device in device manager, but it tells me my usb device has malfunctioned.
At the moment, my thoughts are to open it up, to:
1. Check that the power/volume buttons aren't stuck in some way (preventing the boot command being given correctly)
2. Remove and resolder if necessary internal battery to force a power cycle.
3. Bin it and get something new (it is 2.5yrs old so no big loss i suppose)
Any ideas where to look or similar experiences?
Thanks

Reset the Phone
You need to do a factory reset. Hold volume 'up' button and power button at same time for a minute or so, then choose factory reset.

The battery is taped into the case with double-sided tape - in other words, very gently pry the battery out (from bottom of battery) & leave it out for a minute or two. Then put it back in & try again.
Fixes for the Boot Loop/Frozen ANS UL40
American Network Solutions (ANS) mobile phones provided by Assurance Wireless (Virgin Mobile) have been known to boot loop, freeze, stay frozen, crash, (right out of the box, brand new) and worse there is inaccurate or completely wrong information on how to do a factory reset and reboot the device. Below I will outline how to reboot the phone and perform a hard factory-reset with no home button on this cellphone.
Problem: Phone won’t turn off, won’t restart, or is stuck on and has no removable battery.
Solution: Keep the phone on and unplugged until battery dies or perform a hard reboot (see below).
Problem: My cell-phone is stuck on and there is no home button to do a hard reset
Solution: Perform a hard reboot. To restart a phone without taking out the battery, simply hold the Volume Up button, the home button (do not press if there is none obviously) and the Power button at the same time. While you hold these simultaneously, the phone will reboot in about 5 to 10 seconds.
Problem: I can’t factory reset my ANS UL40 phone (American Network Solutions) from Assurance Wireless by Virgin Mobile because I can’t get into the recovery menu.
Solution: Turn the phone off (or do a hard reset by holding the Volume-Up Button and the On-Button. Phones with no home button all reboot like this so just wait a few moments and the phone will restart.
Problem: My new mobile phone from Assurance Wireless gets stuck on the loading screen!
Solution: Perform a hard reboot (Volume Up + Power) then when it restarts and you’re on the white Assurance Wireless screen, stop holding power and only hold Volume Up. Keep pressing-and-holding the Increase Volume button and after a while you will be navigated to the Factory Reset Menu. You can wipe the cache partition only or perform a factory reset (which will also wipe the cache). To move around on the menu, use the volume keys (increase volume goes up, decrease volume goes down) and to select your entry simply use the power button (the on button). If this still doesn’t work, see further instructions in the solutions below.
Problem: Phone is frozen on loading screen, stuck in boot-loop even after factory reset/wiping cache partition.
Solution: After you have factory reset or wiped the cache partition you can also choose to install an update from the internal memory or sd-card. If you select this option it will perform a more rigorous factory reset then since you won’t have a package to install it will cancel. I’ve noticed my device getting out of the boot loop once I did this process and it was stuck on the boot screen even after I did a factory reset.
Problem: Can’t get to the recovery menu with my government assistance phone.
Solution: Turn off the phone and with the volume up button held down, power the device on. Keep holding both buttons until you see the white “American Network Solutions” screen with the outline of an eagle. At this point release the power button and continue to hold the volume-up key. After about 5 seconds you will now be inside the Recovery Menu and can do a factory reset.
Problem: My phone has no home button and I need to hard reboot to get to the Recovery Menu and perform a factory reset!
Solution: Hold the Volume-Up Button and the Power Button at the same time. for at least 10 seconds. Your device will restart and after the white ANS screen shows, stop holding the power button. Continue holding the increase audio key until you are at the Factory Reset / Recovery Menu screen. Use the volume buttons to navigate the menu and use the on button to select your choice.
Problem: My phone hangs on the blue Assurance Wireless screen.
Solution: See Above.
Even on the Virgin Mobile and Assurance Wireless websites and in the owner’s manual it says to hold the Volume Up + Home Button + Power Key and to keep holding them until you’re in Recovery Menu. This isn’t going to work for two reasons on the UL40: 1) It has no home button! and 2) it will just keep rebooting every 5 seconds if you hold the power button down constantly. You have to hold the Volume-Up Button and the Power Button until the phone reboots and then let go of the power button while still holding the volume up button. Keep holding the volume up key until you’re into Recovery Mode.
I hope this helps as the information online is either incomplete or completely wrong. Some places say to keep holding the power button along with the volume up key and if you do that the device will just keep restarting, effectively creating a boot loop where there wasn’t any before. Genius! lol. I figured this out after my device, fresh out of the box, froze while charging on the blue Assurance Wireless screen. Finally OCD is good for something! These phones are supposed to be a “Lifeline” but I’d be hard-pressed to get ANYTHING on the line with this potato. Avoid at all costs unless absolutely necessary.
Enjoy. :highfive:

Great advice. Have had an ANS UL-40 for over a year, & they truly stink if you can't root them - which I can't since I've no computer access (for ADB). I honestly miss the old android Jellybean phones that could be rooted with just an app. Oh well.
I have a UL40, I tried the factory reset method, it reset but the phone is still suck on the blue assurance wireless screen.
Ps. It's been like this for days. It stays on the blue screen for about 5 minutes, then the screen is completely black. When I try to turn it on again, it's blue for five minutes then goes black.
Help...?
My ans ul40 keeps restarting. Every 2 to 5 seconds, on its own. I tried to factory reset it with the steps listed above and I can't tell if it works because when I hold the volume up and power button, it does two things, the phone will either shut off again and go into the constant restarting or number 2, it will show me a white screen as if to say the holding down of the volume and power button worked, but then it just goes back into the constant restarting... at this point I'm thinking I have to call for a new phone.
I have a ul40, technically 2 because one wouldn't hold a charge and now this one keeps crashing and giving me error codes. I can't afford to just drop money on a new phone (hence why i got this one) and I am FORCED to do a factory reset every 3-5 days because the memory gets so full, even if I erase memory, disable or delete apps and barely use it outside of texting or calling. Its frustrating to high hell. The code that shows up is either "GOOGLE SERVICES FRAME WORK KEEPS STOPPING", or "COM.ANDROID.PHONE HAS STOPPED"
Any advice is helpful advice.

Have you tried taking out the battery for a minute or two, then powering up? (Battery is only held down with tape - it can gently be pried out). The other option is a complete reset - instructions on holding the power & volume keys, etc, are posted already.
this phone seems to ship with a lot of malware factory-installed (and possibly more built into the firmware?) so it's critical to go into Settings->Apps and disable everything that looks suspicious, including the less obvious "notepad" app and "voice recorder" app. this should help your phone run somewhat better but there's some adware still running that i haven't figured out how to disable, so a perfect solution in theory would be to root the phone as discussed in this thread. unfortunately so far there doesn't seem to be a working root for this phone.
I did fatory reset from recovery until arrivet to let us go then skip sim then next as new device/retrive from cloud then lis of wifi appear and stop at this point nothing else appear to enter
what the solution please?????

Poco F1 stuck on boot

Hey everyone,
Hope there are still people around in the F1 forum.
My F1 was sitting in the drawer for almost 2 years now.
I'm trying to boot it now, but it gets stuck in the process. It basically keeps going like this to infinity, i gave it hours and it's doing exactly the same thing.
As you can hopefully see in the video, when i try going to fastboot (by pressing power+volume down buttons) it shows the fastboot logo but gets stuck there.
From that point the only thing i can do is try to reboot normally again, which brings me back to the first state.
Connecting to the computer doesn't do anything.
Any ideas?
Ideally i'd like to keep the data but i'd consider anything at this point.
Many thanks!
Try to restore. Press volume up and power button when logo appear release power button but keep holding volume up until recovery has shown up

Thanks for the tip!
Actually, emptying the battery completely and then charging all the way to 100% (without trying to reboot before it reaches 100%) eventually did the trick and the phone turned on with all the data.
