Boot problems

My scenario:
I updated my N1 to 2.1-update1 by applying an update.zip from the SD card. Everything worked fine for a while until a few days later I turned off my phone. On rebooting, it got stuck at the splash screen. I managed to reboot through the bootloader and got back in but have since had problems with a couple of apps force closing on startup and have been unable to send SMS. I decided that maybe I should start from scratch so rebooted into recovery mode again and wiped data and cache and reapplied the update. My phone will now not boot at all. It consistently gets stuck at the splash screen.
It's not bricked, as I can get to the bootloader and recovery menus but:
a) adb and fastboot won't recognize the phone as being connected
b) on the recovery menu I see "E: Can't open /cache/recovery/command"
c) when going in to the bootloader it complains about not finding PASSDIAG.ZIP
Anyone have any ideas what I can do? I can't connect via adb/fastboot so am not really sure what I can try...

Did you do a nandroid if so I would try to restore and start the update from that point.

I get an error when I go to my bootloader screen asking about passdiag.zip and passdiag.nbh but it hasn't ever caused any problems, it just complains about them. I don't get the issues with the recovery menu or USB though. Fairly sure that doesn't help you, just adding my experience in the off chance it helps someone diagnose.
I don't suppose anyone has any idea what passdiag is?

No one with any idea what passdiag is or what one might do to fix this issue?

Don't worry about passdiag.zip and passdiag.nbh. These files are the ROM dumps if i remember right from Google. Just let that pass. Is your phone unlocked running a RA recovery, or are you still at stock. If unlocked you will have to reflash whatever ROM it was you were using.

So here's how I got to having that error.
Originally I was using the stock ROM. No error.
Then I unlocked/rooted using the guide here. Error started appearing.
After that I flashed Amon-Ra's Recovery: Error still present.
Following that I flashed Cyanogen's Mod. Error still present.
I really would like to get rid of the error, even if it isn't hurting anything. I don't suppose there's a place I could get the files to push to my phone or somewhere in the phone I could tell it to stop looking for them?

[q] stuck in bootloop sprint ls980 please help!!!!

OK to start off i am not a noob at this, i have read though the forms and cant seem to find out why my phone will not come out of this bootloop. This started happening 2 days ago when I went to install a new rom on my phone. I powered down my phone, put it in recovery (Twrp), I wiped everything but internal storage. I then processed to flash the new rom. Everything went great. My phone rebooted and worked fine for the first 1 min, when i tried to pull down the notification bar the phone stuck off and went into a bootloop. I then tried to go back to my old rom and had the same problem (notification bar would not pull down). So i went to plan B and used the Back To Stock Form to restore the phone back to stock. The process went smooth as well not a problem at all. When the phone started up it allowed me to set up the voice navigation and name of the phone, as i went to update the prl and profile the phone shut off again, when it turned back on it starts normally and the goes to the lock screen where i am unable to make any iterations with the screen at all besides when it turns the blacklight off, as i try to use the knock on the LED light turns white but the screen will not turn back on (not even with the power button). Then it reboots to the lockscreen again and continues to do it until i manually force it off. I have tried everything from redownloading the firmware files, tried back to stock 3 times, hard factory reset, and reset in recovery mode. My phone is back to stock but i am unable to do anything with it unless i factory reset and go though the set up again, but even then i cant get a connection (even with wifi) without the phone shutting off and rebooting. Everytime the phone reboots the time reads 12:00am and switches to 12:01 really quick. I cant get a connection at ALL (I EVEN TRIED REMOVING THE SIMS AND AND PUT IT BACK IN AFTER BACK TO STOCK PROCESS.)
Im not sure if the application Dr.Web could possibly be making my phone do this. I did have it installed and did not remove before I tried to switch to the new rom. The anti-theft part was active.
SOMEONE PLEASE BE MY HERO AND HELP........I REALLY WOULD HATE TO DEAL WITH LG ON THIS ISSUE IF I CAN FIX IT MYSELF

god that is really hard to read...did you make a back up before you do installation? if so do a restore, if you dint, download another rom, kernel, put it in your phone, wipe everything except internal storage via TWRP then flash rom then kernel.

I had the same problem except with me, i was just trying to change fonts manually. It went into a bootloop and i stressed dover it for hours until finally i found out that you have to use the lg mobile support tool (you can find it in one of these threads on the lg g2) and revert it back to stock. That fixed it perfectly fine. Its a lengthy process but simple. If that doesn't work you have to do what the lg mobile support tool does semi-manually with another program lg flash tool which is longer but just as simple if you follow the directions given in the thread to the letter.

**** thats not good at all. This happen when I was using my S3, if IMEI is gone then you could not use the phone at all, theres no way you can get it back unless you made a back up. you have to sent it in man, sorry this is as good as hard brick.

My friend also has a lg g2 that i rooted for him would i be able to use a backup from his phone. Also when i turn the phone conpletely off and hold down all 3 bottons it brings me to a hardware key settings it does shows my imei number there. If i sent it into lg would they know the phone was once rooted or does the back to stock method cover it up? Thanks for your help btw

they have coders there, I'm sure if they really want to know they can figure it out. If you send it in to get it fix out of your own pockets (meaning you pay them) then i'm sure they dont care, but if you want a replacement due to warranty then it may be a different story.

I eneded up restoreing my phone back to stock and took it into my local sprint store it cost ne 75 dollars to replace the phone not under warranty (if u have sprint protection its free) i told them i took and ota update and it started rebooting itself. If you do get a replacement make sure u back up your efs files to a safe place on your phone. Theses files can become corrupted by flashing roms and kernals.

Not under warranty? Doesn't it have a 1 year manufacturer warranty? The G2 wasn't released on Sprint until November last year so it should have been covered.
Sent from my LG-LS980 using Tapatalk

Yes its still under manufacturer warranty but when i made a repair order with lg it said it would take 2 to 3 weeks to get my phone back and if they found out it was due to being rooted and flashing roms im sure lg would of charged a arm a leg to repair it. With sprint i got a new phone in 2 days or ordering it.

Please help! Stuck on boot screen

I left my phone charging overnight as I have done many times with no issue. When I woke up I pressed the home button and the only thing that shows was my wallpaper. Wouldn't show anything else. I then did a battery pull. It now gets stuck at the note 4 powered by android screen. A little history in case it helps. This is an unlocked at&t model that I am using on t-mobile. It's not rooted or anything. A few weeks ago I downloaded the recent 5.0.1 small update. In the past week a notification keeps appearing and disappearing from the menu. It was dm software download or something which would disappear if I clicked it.
So it's stuck on the boot screen today. I booted in to the recovery screen. It starts by saying "installing system update" with the little android. Then it goes to recovery menu. At the bottom it says "dm-verity verification failed". I tried to wipe cache and reboot but it still gets stuck at the boot screen. Another small detail is after turning phone off if I plug it in the charger it stays at the grey lighting screen and does not show any battery percentage.
I don't know what to do. I really need my phone today as I am traveling. I hope someone can please help me. Thank you.

In the case u tried recovery now u should flash ur stock rom.

How do I flash the stock rom? Should I do that before trying a factory wipe/reset? I haven't tried that because I really dont want to erase everything unless I have to.

When u do the flashing everything in your device will be lost. So if u do the flashing then u just need to backup all your data.
---------- Post added at 01:05 PM ---------- Previous post was at 01:02 PM ----------
First u have to download your stock rom

Anyone else have any ideas? I really have no clue how to flash the stock rom. Is there a guide I can follow? Thanks

Just google your device name flashing

I would suggest you start download stock as already mentioned by previous mentor
Than try to make a factory reset from recovery while stock is downloading. In case factory reset all your apps and settings will be gone but your data stay untouched.
If positive with factory reset no need to flash stock anymore

I just tried doing factory reset/date wipe and it's still getting stuck at the boot screen. I guess I need help now to flash the stock rom. Again I have never done this so I appreciate it if someone has or could find a simple guide for me. I just don't want to download the wrong file and mess phone up even more. It's an at&t model SM-N910A. Thanks again

How long did you wait after wiping? For lollipop its normal after wiping to see nothing but Samsung boot up logo up to 20 minutes

In response to above. It did the date wipe/reset which did it in like 5 seconds. I rebooted and left it on the boot screen for about 3 minutes. I should wait longer then? Another thing I was going through kies to see if anything could help. I ended starting a firmware upgrade. I entered my model # and S/N#. It then asked me to go to recovery and made it to a screen with an android, "downloading do not turn off target". That's loading now and i'll see what happens. I also checked on google and it looks like there is a program called odin that will flash the stock rom. I need to find that program and also find the stock rom file to download?

Yep. Google for Odin, download and extract it on your PC. You'll need to download a stock firmware from Sammobile for your device. It will be as Archiv so extract it. In Odin click on AP and choose extracted file.

Another update. The firmware upgrade through kies went through fine. It booted up like normal afterwards. I didn't know it would happen but I am back to kit kat 4.4.4 as well. I wasn't too thrilled with lollipop so maybe that isn't a bad thing.

[Q] At my wits end

tl;dr phone is in some kind of bootloop, tried flashing stock firmware (successful but can't get past start splash screen), plz halp me
So I was just simply browsing on my phone on reddit is fun app, some Google Chrome sites, and 9gag. So then I saved a gif on 9gag and the phone just gives up on me. It went straight to shut down without any warning whatsoever and proceeded to restart. Thinking that it was just an unusual one time thing, the phone kept rebooting and I started really getting worried. I kept getting the Samsung Galaxy S4 splash screen and after that a black screen and then it vibrated twice and I saw the splash screen again. Didn't even get to see the menu for SafeStrap. After several unsuccessful attempts, I finally accessed SafeStrap after restarting the phone from download mode pressing the volume down button. To make as much precious time as I had, I made a backup (although I checked enable compression which I shouldn't have but I didn't have a lot of space on my SD card) and made an advanced wipe cleaning everything except the SD card. I then proceeded to flash a different custom ROM (GoldenEye if you were wondering) and hoped that it was just a custom ROM error that kept giving bootloops. No such luck. The different ROM didn't even help. So I went back to SafeStrap and made another advanced wipe. At this point, I decided to flash stock firmware via Odin from this link (http://forum.xda-developers.com/galaxy-s4-att/general/guide-odin-to-stock-updating-rooting-t2926642) with NB1 base. I remember having flashed the non-rootable version successfully and restarted the phone after that. Got past the Samsung Galaxy S4 splash screen and went all the way to ATT splash screen but then it crashed right there. After that, I couldn't figure out the problem and I couldn't flash any more stock firmware (at least from that link) via Odin because I kept getting a fail notice. I asked this question on reddit and the responses kept saying that I may have a defective power button but it doesn't stay shut down and instead bootloops. Should I try to find a new GS4, get another phone or try sammobile firmwares next to see if there's any luck? I really need to save this phone as it is super dear to me. I'm at the point where I can cry right now :crying:
If you guys need any pictures or videos, I will be more willing to do so

I'd say try redownloading the firmware and make sure your cable is good, try a back USB port, etc. I'd guess the firmware files didn't download properly and so it didn't flash properly. Before you do anything though, try going into stock recovery and wiping everything you can from there.

Thank you for the reply. As for the firmware, where should I acquire them? The link I posted has only one firmware (NB1) and I cannot access stock recovery AT ALL. When I do, I can see the blue text in the corner "Recovery booting..." and then the phone restarts again. This is really frustrating

NB1 is the only one you can get, just try downloading either one again.

Recover data from softbricked, unrooted VS980 G2 stuck on LG screen?

One of my friends was having me try to fix or at least recover data from her Verizon G2- it's been stuck on the LG screen for about a week, can still go to recovery/download/other basic screens but that's it, all she did was put it in her pocket and it stopped working. Unfortunately I'm REALLY new to anything Android (please forgive me if I'm using terminology incorrectly!) so I've been lost trying to work this out.
I found out today that she went ahead and got a new phone altogether but she asked me to pull the data from this one. Before this I've tried using LGFlashTool to reset the phone without removing the data, but every way I've gone about doing that has told me that "there was an error connecting to the device" or something along those lines, same in Alligator Toolkit 3.1 and even Windows Device Manager.
At this point I just need to get the data from it, but it's not rooted so I can't install TWRP (not sure about any alternative recoveries), and I can't root it because it hasn't been able to get past the aforementioned screens.
Is there a way to basically just copy all the data on the phone to a computer without a recovery, rooting it, or anything like that? Or is there any way I can install a recovery like TWRP?
Another thing is that strangely last night I managed to make it turn on and work properly, but when I finally decided that it did work and went to unplug it and put it away, it went straight back to the LG screen. I'm not really sure what I did to get it to work that time but I haven't been able to make it happen again.
Sorry if any of this is unclear, I'll be up late available for any clarifications. Thanks in advance for the help!
