I bought this Verizon Galaxy Nexus a while back to use as a media player on a trip.
It already had Paranoid Android on it.
After the trip, I messed around with it, and stupidly wiped everything but TWRP v2.3.2.1.
Now I have a device that boots into TWRP, but thats it. There is nothing to Restore or Install.
I have downloaded updated ROMs, but when I plug into my PC, the phone isn't visible.
Any advice would be appreciated.

I have a good feeling that your pc is detecting your phone because of the twrp. This happened to me. I would download the latest TWRP and flash it using fastboot.
Once I updated to TWRP 2.8.0.x, I was able to use adb again in recovery which it seems like you know how to do. If you have any questions about anything, let us know though. Hope this helps man.
INSTRUCTIONS
-Get to the bootloader with volume up + volume down + power.
-Connect the phone to the PC. Enter at the command "fastboot devices" to see it show up.
-Now locate your newly downloaded TWRP.img. Enter:
Code:
fastboot flash recovery <path_to_recovery.img>
Thank you for this.
I actually got a crash course in ADB last night. I was able to pushe several ROMs into memory, but nothing stuck. They all kept failing.
The phone was rooted and had Paranoid Android on it when I got it. i never had success running anything else on it.
I think your instructions will help me get TWRP updated which should help. So far, I pushed the new TWRP image with adb, but didn't know what to do with it.
I will mess around with it more tonight.
Hi XDA, many threads here have helped me in the past so time to ask another (probably stupid) question. It's a bit of a long story so I apologise in advance.
I've been running CM (one of the nightly builds from about 3 weeks back, don't have the file so I can't say which) on my phone for a while with no issues until a couple of nights ago when it was overheating (charging while playing a game, stupid I know) so I decided to turn it off so it could cool down without taking it off charge.
The following morning I turn it back on to find that it's getting to the blue android head logo of CM and getting stuck there. First thing I do is reboot into TWRP and flash my backup from right after I installed CM. Reboot and... same result. Okay, no biggie right? Time to reinstall CM (the latest nightly build from yesterday) and Google Apps (nano package) via TWRP and reboot again. Still stuck at the blue android head logo. The reinstall was handled after using the Wipe-Factory Reset function of TWRP, as the guide here explains.
At this point I decide to do a bit of research and learn that it's called a softbrick or bootloop and apparently flashing the stock rom can fix it. The LG software suite won't even recognise the device but a friend of mine found this guide so I attempted to run through it. All goes well until it comes time for the software to connect to the phone - I pop it in download mode while putting the USB cable in, the program says waiting for connection, runs for 14 seconds and says it's trying to put the phone into download mode, at this point it fails saying the phone can't be put into download mode.
Some of the comments beneath the article offer fixes like using USB 2.0 instead of 3.0, putting the program into compatability mode for Win7 and running in administrator mode. To be thorough I tried every USB port on my machine (both 2.0 and 3.0) and run the program in compatability mode (with and without admin mode) for several versions of windows. Same result every time.
Another friend then suggests that somehow permissions got borked and it might be worth reflashing SuperSU to the system but at this point I'm at a loss for how to do that. I have the one click root script that I got from god knows where (not this one because that didn't work for me) that has a SuperSU zip in it, presumably it flashes that to the phone when it runs (found this out the hard way because I've been a moron in the past and tried installing SuperSU through TWRP and broke the boot previously, fixed by re-running the one click root script - this was ages ago before even installing CM.)
So right now I can put the phone into download mode manually, get into TWRP and use all its functions as well as connect to my PC and use ADB functions while the phone's in TWRP but can't boot into CM or flash a stock rom. Any help would be appreciated, I've spent a whole day reading guides, asking friends and clumsily trying to fix this only to get nowhere.
Have u tried installing the stock via TWRP? Via zip ... Wipe cache delvik also..

I haven't tried that, I didn't even know it was possible. Could you give me some more detailed pointers on how to do this? I noticed that the stock ROM I have cames as a .TOT file but CM is several files and folders in the zip. Will it install fine from that zipped up TOT file?
Thank you so much for your time.
When the rom is uploaded by the dev its also uploaded in .zip file place it ur system rom just go into twrp recovery flash the the zip file before flashing wipe cache n delvik too its easy as 1,2,3 search here on xda for ur compatible model

Hello everyone,
yesterday I flashed a new Cyanogenmod 14 nightly (12062016) for my G4 from earlier nightly in TWRP. After reboot the phone keeps going back to TWRP and I can't seem to get it to boot to system..
I tried factory reset, reflashing back to old nightly, flashing stock.. but nothing seems to work.
Also tried doing this in the TWRP terminal:
dd[space]if=/dev/zero[space]of=/dev/block/platform/f9824900.sdhci/by-name/fota
Didn't fix the loop, I guess because it wasn't the OTA update that caused the problem in the first place.
If anyone has an idea, I would greatly appreciate the help!
Thanks.
If you can reach download mode you could try reflashing back to stock then starting again.....Hope you get yours fixed - Sorry to say this but mine did a very similar thing only 24 hours before you posted!!! Only mine was on stock FW and was in use at the time - I've now had to swap it as valuebasket who sold me the phone have ceased trading. If yours is a UK model you may be able to get it replaced under warranty - believe that LG guarantee their phones for 2 years and a ruling by the European court said that flashing a custom rom doesn't invalidate any warranties.
I have the same exact issue, I also flashed the latest CM14 nightly and cannot get the device to boot any rom.
I have even tried flashing stock rom but I get the same problem.
From what I have read, the bootloop issue happens once the device boots but I don't seem to be getting that far.
Any ideas?
Ran into the same problem 3 days ago. This is the first time I have encountered a non-revertible issue in 3 years as a cyanogenmod user. This changes my opinion on how safe it is to make use of a custom ROM. I tried to wipe everything, reinstall TWRP, change TWRP with another recovery, reinstall a safe NAND backup of mine.....nothing.....it went into boot loop. Before I read this post, I was convinced my phone encountered the infamous G4 bootloop problem.....now I see there are other examples, so it shouldn't be the case. Long story short, I had to check my device in at the LG assistance, with 25 days as time forecast.
The guilty nightly was 20161205.
I have never seen anything like this...
This has solved it for me - I installed LG Bridge and flashed the factory firmware using the tool. Now it seems I'm back on stock but at least it's working.
got mine working. I had to install LGUP and flash stock ROM. Once flashed I installed CM14 and I am back up and running again.
I tried LGUP but it could not recognize the device while this was looping.....a bad experience......
I have the same issue. My phone was updated to 20i via the original stock firmware, then I put twrp 3.0.2-0 and cyanogenmod on. I did a cyanogenmod update from within cyanogenmod, which just booted into twrp, then I manually installed the update zip that cyanogenmod had downloaded, then it always boots into twrp. I wonder if initiating the update from within cyanogenmod was the cause. The phone is not detected by LGUP or LG Bridge. I've tried this on a win10 machine, and a win7 vm from linux. I have access to twrp, and download mode by doing the reboot into bootloader from within twrp.
If those people who have fixed this could give more details about how they did it, that would be good. What exact steps did you take? What stock firmware version did you have before installing a custom rom? What OS version were you using? What twrp version?
Well. Mine got stuck in bootloop for the second time today. What is going on? In between the two bootloops I had one good update with CM. Using TWRP 3.0.2.1. Steps to reproduce failure: updating CM from within CM, it autoreboots into TWRP and after that nothing happends, no autoinstall. Then after a manual install of the new CM the bootloop starts.
Resolve the problem:
* Install LGUP 8994 DLL Ver 0 0 3 23, Install LGUP Install Ver 1 14, get the latest KDZ
* Get the phone into download mode with usb cable and after that in firmware update mode
* Startup LGUP and choose refurbish and select the kdz file.
* After that you can boot into your stock LG firmware again, reinstall TWRP an CM. If you want so.
Read that it is advised to manual update cm from within TWRP. TWRP will get an update in the future to solve this bootloop problem.

I second that. Same issue and neither LG Up nor LG Bridge will recognize my device. Looking in device manager there are no serial interfaces. Do I need a special driver that provides a com port for a phone in recovery or fastboot mode?
---Edith 2016-12-12: Found a solution for my issue:
The phone has to be in _download_ mode, not in recovery or fastboot. After realizing that I have to boot the phone in a different manner, it will be recognized by LG UP.
Here is how to boot the pone in download-mode:
- Power off your LG device.
- Press and hold Volume Up button.
- Connect your device to PC with a USB cable while holding the Volume Up button.
- You’ll boot into download mode with “Firmware Update” written on top of the screen.
Now everything is fine again.

I was able to get out of that by also wiping by-name/misc. Don't do that, though, because then your wifi mac address will get messed up and you'll spend all day looking for a permanent fix for that.
I suggest reflashing a stock KDZ using LGUP, as others have said. You can get the usb drivers from LG Bridge.
I will release a fix for that soon. Check the twrp thread for updates on this.
Hi
I also have this problem
I installed cm-14.1-20161201-NIGHTLY-h815 successfully and was running it for almost 2 weeks without issues, today I updated to cm-14.1-20161213-NIGHTLY-h815 from cmupdater and I have been ending up in recovery every time I rebooted.
I tried flashing the latest cm recovery and reflashing the rom, with full wipes but no luck.
Full steps of recovering would be appreciated (for example, there are comments about flashing the latest stock rom, but a link to this rom would be helpful)
Thanks
Good news regarding this:
http://forum.xda-developers.com/showpost.php?p=70082901&postcount=213
The above will fix TWRP bootloop issues as well and I also released a first h811 version which should allow installing CM etc as it should.
Keep in mind that this is a BETA and not an official TWRP release.
Please report back in the above thread!
.
Does your twrp beta really fix the boot loop even it is already happening. What do I have to wipe? I have not managed to get out of the boot loop despite intalling it.
Is using using LG Up to flash to the stock rom really the only option?
Edited 2017-01-25 2:45 pm:
Well, sometimes you just have to be patient. Powered down the phone and when th H815 restarted CM did boot. Great. :good:
Hey, I just want to share a small detail, possibly a fluke that helped me overcome the bootloop.
So...I started with a fresh, stock H815, I don't quite remember the firmware version..it was something like version "20g"..
OK, I looked up several guides and tried to get the newest stable versions of each tool. I went through with the official bootloader unlock, then moved on to rooting: Kingroot didn't work for me so I went on installing twrp in fastboot mode so I could afterwards install supersu and root.
I got there eventually but first I was stuck in bootloop - kept ending up in twrp interface. I found the 2 dd commands but those didn't work for me as the msm_sdcc folder did not exist, but instead there was a "f9824900.sdhci". Tried to overwrite this one ...but as others have stated as well, it didn't work.
At that point, I had nothing to lose, I was starting to accept that I had soft-bricked my precious G4 so..I went on installing the DU 10.6 7.1.1 rom and the stock gapps, wiped dalvik, rebooted and held my breath...not literally
About 12 minutes later, after an endless red, spinning logo, my shiny ping pong paddle showed me a different screen, a fresh start welcome screen .
Almost 24h / 10-12 reboots (twrp included) / 70+ apps installed and removed later, the new OS holds around 2G ram average, a bit better battery life, smoother transitions, flawless navigation, flush streaming over both 3G/LTE & 2.4/5 G wifi.
FYI the reboots were intended, wanted to see consistency in boots - we're in the green . Now testing long term stability with moderate/high usage.
There is 1 aspect I noticed, there are a couple of contexts when the interface burps (several menus, various situations, never in apps) and resets back to homescreen...but I think that's more of a launcher topic than an OS one.
Other than that, so far I'm happy with the mod.
Hope my experience helps others that might be in the same spot I was or at lest boosts their confidence to try out a decent idea they might be pondering.
My Zenfone 2 (ZE551ML 4GB) dilemma:
*•*I unlocked the bootloader with the official bootloader app
*•*I flashed the latest TWRP via adb. In the recovery screen, I saw an android showing error. That's when the panic started.
*•*I Then I rooted my phone with the one click Zenfone root application (available in XDA)
*•*I installed the official TWRP manager from the playstore and flashed with it. That also didn't solve my problem. Actually, a new problem set in. The phone started bootlooping IN RECOVERY.
*•*I rebooted the phone and then flashed an old version of TWRP for my phone. That solved the problem.
*•*Now, I wanted to flash Lineage OS in my phone. According to a YouTube tutorial, I copied my required files (the custom ROM and OpenGAPPS) to my Micro SD and then from twrp's advanced wipe, deleted everything except for Micro SD. I know that was an extremely stupid move but please bear with me.
*•*Deleting everything made things hundred times worse. It seemed impossible to get the phone into recovery mode again. But after a long time, I did.
*•*Now onto flashing the new ROM. I did a factory reset with twrp and then flashed the ROM and immediately got Error 7. By googling a bit, I found that the only way to solve this problem was by deleting the assert lines from the updater-script in meta/com/google/android inside the ROM.
*•* When I reflashed it, the process completed but it showed an error: (E:unknown command [log])
*•* Then I overlooked it again as a quick google said it didn't matter. Then I successfully flashed OpenGAPPS. I rebooted my phone and it kept bootlooping until it was back in the recovery screen. Weird right?
*•*I didn't seem to find any workaround so I decided to restore stock ROM. I downloaded it and flashed it. It succeeded. I rebooted my phone. And. .
*•*My phone now vibrates when I power on the phone and then it shows a black screen. It reboots automatically. I know it does as the phone vibrated periodically after the reboot
*•* I also can't go into the bootloader menu. My phone seems dead but I really need to revive it. I can't afford a new phone. Could you guys help me out please?

Did you flash the MM bootloader compatible TWRP mentioned in the OP for LineageOS? That solves error 7.

HI,
I am not new to flashing phones and tablets, but I am a bit confused about the new partition format.
I have a nokia 6.1.
I want to flash the official lineage 18 ROM on it.
I downloaded the latest version , and also the latest lineage recovery.
I followed the install instructions on the website . I believe, exactly.
But after I have executed this command '' fastboot flash boot xxxxx.img"" to temporarily boot recovery, the phone stays in download mode and does nothing.
I then thought maybe I need to reboot?, and power down, because the next thing on the lineage install instructions is to start the phone having powered down.
Anyways, when it boots up, it hangs and stays on the android one screen.
Power/Volume up does nothing.
Whats worse is, it is no longer recognised in ADB.
I was really worried. I let the battery die overnight, and then tried to get some response, but no - still stuck.
Finally, after more fiddling, I got it into download mode, and was able to flash stock using OST.
I tried again - same thing, and once again luckily managed after an hour or so to get it into download mode.
So I have reflashed stock, and wondering if somebody a lot brighter than me can give some advice??
Currently on stock android 10, but would much prefer lineage 18 , as I have no need for google services.
Can only think something is going wrong with whichever partition I am temporarily booting to recovery?
Many Thanks ( with a relieved sigh for escaping a brick )

Something similar happened to me, it turns out that from android 10 stock you have to first:
fastboot flash recovery xxxx.img
you will get an error in the cmd, that's good, now
fasboot boot xxxx.img
.
this was mentioned a long time ago but was never mentioned more in other threads
if you get stuck you can use ost la. also remember the slot A B when you flash the rom

Hey bro same experience, thats why im stock in android 10 with unlock bootloader. but i successfully flashed lineage with unofficial twrp but the problem is i cant flashed gapps thats why i cant install pre apps and cant use the default message and call. please help me
