I've got stuck in boot loop twice in a row after spending hours restoring phone with different method. Maybe I should have learned my lesson not to touch TWRP. Has anyone backedup and restored without a problem? Is there a way I can fix this issue without starting all over again?

Ive backed up and restored twice now with no problems, did you completely wipe and factory reset? You have to do it in that order.
I forgot, and just restored. But that shoulnd't cause bootloops. Ive used TWRP before on gnexus. what did you learn from your first bootloop error? I saw you had many posts. What have you changed to fix that ?

This isnt the Gnex, i know what you mean, this phones recovery method doesnt work the same as the nexus.
I learned this from other people's trial and error actually from this very g2 forum. With this device it requires a complete wipe and then a factory reset.otherwise boot loops will occur.

in your experience, has how you flashed TWRP mattered? What about how you booted into recovery? I recall you bricked not trying to restore. is wiping the only thing you changed to prevent the boot loop?

Yes, ive had one bootloop from using TWRP but a full wipe and FR resolved this issue. I did brick once by taking the verizon OTA while having TWRP. But that was a month ago and I tried to restore from my backup to no avail though. This was fixed by the devs. Anyway bottom line when I ran into bootloop issues I just did this methodology and it worked, its def different from how we use TWRP on the Gnex.
Is this what your asking about or no?
I ran into the same problem but fixed it using the method in "go back to stock" thread. The mistake I made was that I chose to format my internal storage in the wipe menu so i couldn't restore either lol.

Can you point me to a method to install via ADB? I am confused about loki's involvement.
FWIW, I'm using TWRP without issue so far. Very easy install and I've done two backups, but have not had to restore anything yet.

Holy Crapshoot that was easy... how do you reboot into recovery using hardware buttons on this thing?
I use the clockwork mod app .. if you use the hard buttons I think you have to choose the factory reset option and then that will take you to recovery. .. I have not used that method. .. just what I have read. .. vol down and power. .please research that first

This is about the 15th post I've seen this week about someone screwing up their n7. If there already isn't one there needs to be a step by step video for the correct way to unlock, root, and flash Roms. I suggest others read heavily before doing any flashing. Its bad enough the boot loader is already screwy.
The toolkit does everything for you. All in one method and you're done.

I had this problem happen with my Xoom.
Boot into the bootloader from recovery. There should be an option to do so.
In the bootloader flash a different recovery.
Then reinstall your ROM. It should boot.
If that doesn't work I would suggest flashing the stock images in fastboot and starting over.

I had a similar problem on my og evo. Try seeing if you can flash the recovery from a computer while booted into cwm. Then it'll reboot into new recovery, you flash rom, and you stop sharding your pants

Hmmm. You should have a working adb while booted into a custom recovery. Are your drivers installed correctly?
Also, the reason why you computer sees the files is because with mtp it caches the files.

Sorry I wasn't trying to bust your stones. I haven't rooted yet because of all of the posts like yours. I've just seen more problems with flashing on this device then any other that I have with my past Droid devices. What we really need is apx (spelling?) Drivers and n7 files for a sure fire recovery from any disaster
Hopefully I don't have to start another thread.
I too think I bricked my Nexus 7.
I was having trouble and I accidentally cleared a file from the System UI app (its a system required app) which caused me to loose the 3 buttons on the bitten of the screen.
So I went to CWM to do a restore which said it failed.
After that it would not boot.
Its just stuck with the Google logo on the screen.
I held down the power up & down volume buttons and I get a screen that gives me that START button on the top right of the screen with the text in small size on the bottom left.
I can use the up and down volume to make the start button change to recovery mode or bootloader but activating them just goes to Google logo.
Can I recover or is it totally lost?
I also don't remember if I left the Nexus 7 in Debug mode which is usually required to perform custom Roms
Thanks

You may find help there.
UPDATE: So the issue was a misset flag in misc, meaning that the phone can only boot into recovery. This happened when you used the hardware keys to boot into recovery. Usually you could fix this with adb, but adb in the current G2 build of TWRP wasn't working.
So, until ADB works in recovery again, don't try to flash it!

I don't see you making it to twrp without a boot loader, but did you possibly check anything besides recovery in flashify?
Sent from my LG-D800 using Tapatalk 4
That's is what happens if you format system. Did you make a back up in TWRP? If system had not been formatted then perhaps factory reset us a good option.
First I would force a hard reboot by holding power button until it turns off.

im also stuck at TWRP but i do have access to adb and adb sideload
i was wondering if it would be possible to sideload an TWRP from someone who had a working G2
I've researched it and cannot find a answer. Say if you get stuck in a boot loop and want to flash a nandroid backup or something. The only options I seen with the buttons when the device is off or whatever take you into download mode or a mode that only says factory reset.

On the Verizon model I have TWRP installed and hold power on+volume down and when it says the factory reset I just go ahead through it. The phone still has all your files. It just ends up wiping the OS.
Just my .02 cents because I've been in that position.

^ that's what I meant. It's been a long day and I confused what you asked with something else.
Let me start off by saying I apologize if this is posted somewhere already.
Here's my situation. A couple days ago I lgflashed back to stock. All went well. I then rooted and installed TWRP. No issues at all. I didn't take an update, modify the stock ROM or even flash another ROM. Just ran stock rooted. Today, I pick my phone up, go to turn it on and I'm in recovery. No big deal, right? Well I can't get out of TWRP. My backups are still showing, but when I restore it and reboot the phone I'm right back in recovery.
I can't get into download mode either. Not sure what happened and everything was fine earlier in the day. Any thoughts?

I'm so glad your back up and running again. I've been following your thread. And thanks for sharing the fix.
Does that mean that without your knowledge, your phone may have probably automatically updated itself (OTA) when you left your phone overnight? That's why you were stucked in recovery? Because it seems so odd that you didn't do anything wrong and it suddenly behaved that way. And I have read somewhere here that OTA just installed itself automatically without user intervention. So confusing if that did happen. How is that even possible?

It took me to my recovery (Philz Touch recovery) then I attempted to reboot my phone but now it just keeps going back to recovery and wont go any further. I've tried to install another rom but it still goes right back to recovery after I reboot. Please someone help me out here. I'm pretty I'm not bricked but cant figure out what to do to get to my phone. I'm thinking I need to restore my phone back to factory and start again.

Rule #1. NEVER INSTALL OTA UPDATES IF YOURE ROOTED!
Just saw your other thread. If you are not confident using adb just get yourself an otg cable, put twrp on a memory stick, mount the otg in philz and flash twrp from the memory stick. You can then use the terminal in twrp.
PS. A micro usb drive would work just as well.
