Stuck in Boot Loop after Stock Restore

Stuck in a boot loop after attempting to restore my T-Mobile 801.
It boots up to the T-Mobile splash screen does its little ding a ling thing then 10 seconds later restarts the loop.
I used this http://forum.xda-developers.com/showthread.php?t=2432476
Any other ideas?

Looks like I got it, I did a factory reset on top of it and seems to be working again.

Can you tell me exactly what you did? I seem to be having a similar problem with the Verizon G2 and can't get anything working.

After I ran the factory flashing tool, the phone would boot loop (I think most likely because the settings and profile from the last rom wasn't reset by the tool.)
So what I did was use the factory recovery option in the phone by doing the following.
1. Power down the phone (Hold power for 15 Seconds)
2. Press and Hold Vol Down and Power
3. Quickly after seeing the LG logo release the power (while holding Vol Down still) then pressing and holding the power again. You should get a white screen asking if you want to reset your phone press Power to Confirm twice.
A little android pops up and does some work then reboots your phone. The phone should boot after that.

[Q] Bootloop, no recovery - how to shutdown the phone

Hello,
I'm on LG G2 Stock Rom on Kit Kat (4.4.2). The phone is rooted but no custom recovery as I just need "root" to run Titanium backup.
Yesterday, I attempted to update the 1 XML file to increase speaker volume. Upon restart the phone will stuck on LG logo and does nothing.
I can access download mode. So now, i'm downloading LG Flash Tool and KDZ file for my phone to flash all back to stock.
The question is now: how do I turn off the phone? Pressing power button will simply restart the phone - it never goes to off.
Another question: if I don't install any custom recovery, is there any stock recovery installed? When I attempted to go to recovery (by pressing volume down + power method), I was presented with Factory reset questions. I clicked OK twice and then Android logo appears (it seems like it's attempting to really do a factory reset) and then phone reboots.
If I can go to stock recovery, I hope I can access the storage inside and redo what I did yesterday.
Anyone can help? Or share some knowledge?
Thanks

The latest software upgrade was installed by using LGMobile support tool. I'm back to stock and finish with ioRoot.
Now, going to use AutoRec to install recovery (better to have custom now, so if this happens again, I have a way to access my phone data).
No answers given but it's no longer urgent now. Still if anyone found a way to off the phone when boot looping other than waiting for battery to run dry, by all means, please reply the thread.
Thanks.

Unplug the USB cable if it's plugged.
Hold power button for like 30 seconds straight.

To turn off phone ,just push volume down and power button same time for like 7-10 sec, it will be like restart , but keep them pressed until screen shuts off again (it will take less then 1 sec). Thats all

I didn't time 30 seconds, but I did press power button for a long time. Is this method for when you can use the phone? Mine is during boot loop.

I can't say for sure now, since I have my phone backed-on. But I sort of press these buttons for a long time at the beginning (when I wasn't really sure how to go to recovery mode). But good to know about this - (for next time ).
thanks both!

Only method i know to completely shut down phone in any situation is what i already wrote in last post.

Agreed.
it happen to me too when I try to install MIUI ROM.
Pull off USB cable and long press power the power button

Thanks. I'll remember this, if I got unlucky and stuck in booth loops.
For now, I installed recovery, so hopefully if this happens, I can still access my internal folder and do the require changes.

Bricked (?) phone

I have Cyanogenmod 11 on my LG G2 and everything was working fine until I plugged my phone in to charge it earlier today.
Now it's stuck at a firmware update screen and no matter what I do (even trying to boot into my sideloader) doesn't work anymore.
Funny thing is, it booted normally into Cyanogenmod a few hours ago, but now the problem is back. Any help please?

You can manually reboot into recovery using volume down+power button. Holding the power button forces a reboot, so hold the combination keys after it reboots. The phone should show a white screen that asks about factory reset, ignore and follow the instructions listed then recovery will boot.

[Q] Help please !! Autostart f bootloop "Recovery Booting screen" after flashing Twrp

[Q] Help please !! Autostart f bootloop "Recovery Booting screen" after flashing Twrp
Long time xda lurker here,
I have just thrown my t mobile note 3 into an autostarting bootloop that i dont know how to recover from. I have successfully used this same process 4 times on 4 devices, S 3, tab 2,galaxy light and lg volt. Although this time i used mobile odin as the flash tool.
I flashed twrp to the note 3 because it didnt have any recovery at all. Ive had this phone rooted for about a year without a recovery. After flashing twrp now it constantly autostarts to the logo screen and in top left corner it says recovery booting then it restarts with the same result. Ive tried leaving the battery out for an hour but when i reinsert it, i dont even have to push power and it starts bootlooping again. I cant get in download mode,safe mode, recovery mode, anything mode. Im at a loss. Any advice,any at would be appreciated. Is there any way to fix this.

If the phone turns on by itself when you put the battery in then it's almost certainly the Power switch on the mainboard or the plastic Power button (which is what we interact with).
If that's happening on your phone the first thing to check is the case (if present), to make sure it's not pressing on the Power button.
Next would be to take the phone apart and gently pry the plastic Power button off (there's two legs that hold it in - be careful not to snap them off).
Finally, the Power switch itself - it may just be gunked up, in which case you can try compressed air or electronic contact cleaner (be sure to remove the battery first!) and exercise the switch to get it working.
Otherwise you'll have to replace the switch.

I am going to give that a look right now but it wasnt stuck before flashing twrp. Mobile odin said it was going to restart then it immediately started doing this.
Ok going to check power button now.

The power button seems to be clean on the board and its free on the case, unfortuanately that wasnt the problem.

I've had this before and in my case the Recovery is in place but the boot loop will not let you access it.
Try forcing the phone down by holding down power for >8secs. Then as soon as it goes off, press Vol Up + Home + Power to go to Recovery. If it works, Factory Reset and see if it starts.
If that doesn't work, (Factory) then try flashing a ROM from your extSD if you have one, or flash the TWRP Recovery from there.
If that doesn't work either, remove battery and as you put it back in, have Home + Vol Down + Power pressed as you push battery in - just have battery sitting ready to push in with 1 finger holding it, press the 3 buttons and push battery home. Go into DL mode and Odin a firmware. Get the TWRP .tar file from TeamWiz and flash it from Odin after the ROM. Take the tick out of 'Auto Reboot for both processes. Take phone down, restart in Recovery and flash SuperSU.

Ok journeyman16,
Trying those 1 by 1 right now. Hopefully 1 will work, thanks for reply.

Nothing stops the "recovery booting" bootloop. Although for some reason i now have to actually push the power button before the power comes on after a reinsertion of the battery. But still same bootloop. Idk getting really discouraged with this one.
By the way, I do have an ext SD card with 2 nandroid and a titanium backup but they are useless with what it's doing

That's strange. It might be a timing issue where you aren't doing the DL mode buttons quick enough. DL mode should be available if it gets far enough to try Recovery boot. Did you try having the 3 buttons pressed and holding them down before pushing the battery in? (as in Vol Down + Menu + Power) I ask because it can be awkward to do it all at once - and it takes only a split-second lift of a finger to miss the boot.

Yes i have tried it a hundred times at least, lol. I was holding the buttons then pressing it against my leg to insert the battery fully.
I dont understand it either. Im at the point of just leaving the battery out for about 8 hrs then trying again, basically a hope and a prayer situation.

After my 2 1/2 hrs of sleep i put the battery back n and it went in download mode thankfully.
Tried to start it normally but it just loops to logo without recovery booting on thr screen.
Guess i wiped it somehow with mobile odin. Idk.
Thanks for all the help.
Ill be using regular odin when i get home to restore it.

Note 3 is working better than new
As an update, I ended up putting the tweaked ROM with custom kernal on my device and it just purs along at lightning speed now.That's an absolutely wonderful ROM. I highly recommend it. Only problem is if the battery dies it goes into a bootloop but as soon as I connect the charger it boots up. Not a ROM problem I don't believe though. Oh well thanks for the help guys.

H918 Issue...

So a Tmobile update came on my phone and I decided to click update for some stupid reason... Its early.
I was stock rooted with TWRP installed.
After clicking that it rebooted and went into TWRP recovery. Whether I reboot or turn off and manually go into recovery I can't get it to reboot normally whatsoever.
I tried to flash WETA rom and everything went properly with the install but affter the reboot I am still left with TWRP.
Any suggestions on how to get my phone working again. I am downloading the 10i KDZ file now but was hoping there was another answer.
Thanks for any help or suggestions.

Power off or pull battery for a sec.
Hold vol down and power button - as soon as you see LG logo - release and immediately re-press power button only while continuing to hold vol down.
Factory reset screen will come up if you did it right. Use vol down to select YES twice to factory reset. ( It won't really reset anything but the recovery boot trigger ).
You'll end up in twrp. Just select reboot system and profit
