[Q] N4 Soft-Bricked - NRT Not Helping - Nexus 4 Q&A, Help & Troubleshooting

So I wanted to try Cataclysm, but was having issues switching to it from PA. It always kept booting into PA so I decided to do a full wipe. I did a full app backup and a nandroid backup using NRT. I first tried a regular factory reset, but eventually decided to wipe everything, even /system (a mistake, I now see). After I did that, I tried using NRT to flash stock + unroot. The NRT script gets through everything fine until it gets to the terminal part and says there's no 'boot.sig', 'recovery.sig', or 'system.sig'. It also fails the baseband version check. Don't know if it's even relevant, but it says something failed so I thought I'd include it. After that it tells me it will look like it's boot looping, but it just sticks in fastboot mode. If I wait 20 minutes nothing happens. If I push START it hangs on the Google screen but never gets any further, even 30 minutes later. I've tried pushing a custom zip and install in in TWRP. I've tried flashing a new kernel. Whatever I try I cannot seem to get any further than the boot screen. At this point I'd be happy with stock. I just want my phone back. What do I do?

I'm assuming NRT is a toolkit?
From here on, don't use a toolkit if you know how things work. Manual is the way to go.
Boot into fastboot, choose recovery, go into TWRP, advanced, ADB SIDELOAD.
Now use command prompt or terminal on your computer (depending on your OS), navigate to where you installed your toolkit, there should be a .exe or .sh called adb and fastboot.
Download your preferred rom and gapps, transfer it to this folder.
Now simply do a command "adb sideload *zipname*.zip " and it should transfer and flash your phone.
Don't flash a kernel yet, wait till you finish your first boot, then only you flash it.

I tried exactly what you said to flash the stock image. The terminal said it had transferred 100%, but TWRP said the sideload failed.

that's because you can't flash the stock image like that.
Download CM and try.

It worked! Thank you so much!

Fastboot> Recovery dosen't find *.img file on SD card

Hi Guys!
I am trying to root my nexus, unlocked it, installed the right usb drivers, I can see the phone and everything looks right.
Downloaded Superboot for ERE27 with himem enabled and ran this. no problem.
I put the img file on the SD card and when I boot the phone in Fastboot / Recovery it does not find and img files on the SD card.
I tried 2 different cards and also different img files.
When I do this I get first the message no images found than I see the droid with a triangle and a ! in it. - Have to pull the battery.
Ideas anyone?
Thanks
What are you trying to do?
1) you had to unlock the bootloader which enables you to install a new recovery image (which is needed to allow you to install new roms)
2) you had to apply the recovery image Amon RA via a command prompt and a batch file if you use Windows. The phone's USB connection needs to be in development mode and once the batch file executes and successfully finishes you need to reboot the phone.
3) you restart the phone into bootloader mode, use the volume rocker to select the recovery console. If you end up with an andriod and exclamation symbol the Amon RA recovery file was not installed.
4) the new recovery console allows you to clean the SD card. Install roms from the SD card and some other commands. The Roms for the Andriod are in ZIP format and do not need to be unziped. In other words all you need to copy to the SD card is the full ZIP file (approx 75MB) and install that directly from the recovery console.
If your android stays in the booting sequence which is shown as the X with flying little pixels, it's most likely because you did not wipe the device clean first. That item is in the recovery console as well.
Hope this helps. I am just as new to this as you are.
You didn't unzip them did you?
You're trying to root with superboot. Great, but the recovery is not capable of flashing .img files, only .zip updates and roms and such. .img files have to be flashed using fastboot, not recovery, and are flashed from the connected computer.
If you read the superboot instructions from wherever you got the file, you'll see that you have to put the .img in the same directory ON YOUR COMPUTER as fastboot, connect via USB, boot the phone into fastboot, then enter the appropriate command line on the computer to flash the file.
If you've done that, then you are officially DONE with the rooting process.
Also, make damn sure that the superboot version matches the software version on your phone. They're both ERE27, right?
I'm not sure what anosis's post is talking about, but that looks more like the process for installing a custom rom (ie cyanogenmod), than rooting.
To root your phone, you DO NOT need Amon-RA's recovery. You only need that if you want to install custom roms, etc. It wont hurt to have it, as it includes many more functions than the stock recovery, but just to root, you don't need it.
Summary:
If you flashed the superboot.img from your computer via fastboot, your phone is rooted. Done.
You don't need to do anything in the recovery at all for rooting. Only for installing update.zips and custom rom.zips.
Hey, So I have been scouring the forums trying to find some answers about this and you seem to be the closet to my situation. Here is what I did:
So I was running a CM9 Aplha, reverted back to stock 2.3.6 [1ada25375426.signed-soju-ota-189904.1ada2537]) so that I could then apply ICS update [VQ8PQk_V]) which I sucessfully did. This was about a month ago and it was all going well.
Then yesterday I wanted to upgrade to 4.0.4 [hR7QFEtn] so I did and superuser wasn't working properly but then I reinstalled it and got it to work. However I got to the point where everything was working fine EXCEPT for the Google Play store kept on force closing. I spent hours trying last night and could not find a solution.
I tried restoring the previous ICS update that I had and it worked, and then I tried updating again. Also side: My clockwork was on the fritz lately so I was using Zedowmaxs force into clockwork recovery image [fastboot boot recovery3101.img] to force it in sometimes.
Anyway bottom line here is where my REAL ISSUE begins. I decided just to wipe everything and start anew. I factory reset/ wiped properly [cache partition and davliche cache] and then locked my bootloader again. Then tried rebooting. Got stuck on Google screen. Then I unlocked my bootloader again. Tried again, same issue.
So, here is where I am at. Cannot get into recovery from fastboot, takes me back to fastboot. AND, everything is wiped because I locked/unlocked my bootloader. All I can do is adb commands.
I don't know what to do from here and there is a lot of things going on. If you could help that would be great!? What I am going to try next is to flash some recovery on, but I don't know which one/ try to mount a file to my sd card from adb commands.

It looks like the time when you were locking-unlocking the bootloader, you messed up the recovery. Since your phone can get into bootloader menu, I think you can get out of this issue.
Here is what I would do.
1. Unlock the bootloader.
2. flash clockworkmod recovery using fastboot USB.
3. Download recovery-RA-passion-v2.2.1.img, put it in C:\fastboot\
4. Shut down your phone. Then start your Nexus One in Fastboot mode by holding down the Trackball and press the Power button.
5. Connect your phone to your computer. Open a Command Prompt (Start -> All Programs -> Accessories -> Command Prompt), and run the following commands:
cd C:\fastboot
fastboot devices
fastboot flash recovery recovery-RA-passion-v2.2.1.img
now see if you can get into recovery. If you can, just flash a custom rom using install zip from sd card option in the recovery
I didn't read all the replies but fastboot reads from your PC's disk not the sdcard, unless you are running it through shell or something?

bricken N7, no OS installed

i was stuck in a bootloop after flashing a ROM, and didnt have any backups or other ROMs on the devices storage, so i was attempting to push files to it via ADB, but it wouldnt connect. i went back into the custom recovery image, and accidentally wiped the whole thing, so now i have no OS installed, and not even the seeminly 'faulty' ROM in /sdcard either. i can still get into the bootloader and the custom recovery, but cant seem to get it to connect to ADB. any ideas what i can do?
If you could boot into fastmode, then just flash stock rom.

how do i boot into fastmode? all that i can access is the bootloader, and TWRP. when on the bootloader screen it sort of connects to my PC. i can go into device manager, and will see 'android bootloader interface' in there, and i have updated the drivers as per the instructions in the nexus root toolkit, but it wont seem to talk to ADB for some reason.
edit: ok, this is really odd. when i use the NRT to try pushing a zip file, if i start the it trying to push the file, then open a command line and use 'adb usb' NRT will say that it has connected to the device, and goes through its various steps, and ends up booting the device into recovery, but the actual zip it was supossed to have pushed isnt there...
it made it enter twrp, so it must be communicating in some way, but when i type 'adb devices' it doesnt show up...

Stop using the toolkit and read the sticky that's not too far above your post... the one titled, "[GUIDE] Flashing a Factory Image with fastboot / return to stock." Coincidentally, it happens to be exactly what you need.

You don't need ADB if you are in the bootloader- you use fastboot.

[Q] Factory image restore fail : stuck at writing system

Hello everyone!
I tried to restore the stock image using Nexus 4 Tool Kit (both the original one and the Wug's one), and everytime I tried, the script stucked at "writing system".
I manually flashed system and userdata images with Wug's tool kit and everything went well but I only have 5Gb memory instead of 16.
Does anyone know why?

In future, don't use a toolkit. Do it yourself
I'm having a similar problem to the OP - I'm trying to do a factory restore, and am unable to flash the "system" image. I can't boot, recovery mode won't work anymore (I get a red warning sign instead)...
I think all of this has to do with me being naieve and following a youtube video instead of the CM wiki to install CM 10.1.

When going into recovery the warning sign is the splash screen for stock recovery. This likely means that you have not yet flashed a custom recovery yet, which is necessary to flash CM. First read this guide to unlock the bootloader (if you havent already), then flash a custom recovery (preferably TWRP). After you have installed the recovery, download CM as well as the latest gapps package and place them somewhere on your internal sd. Boot into recovery and go to the wipe menu, then swipe to factory reset. Finally flash the rom and gapps, and then reboot.

if you are doing a factory restore and DONT need to flash everything individually than don't. yes its good to know how to do it manually but if your flashing everything back just use the script that google provides.
reboot to bootloader/fastboot and run the flash-all.bat file and its all done for you. no toolkits no playing with commands that you dont know properly etc.
if you dont know how to do it right pick the least complicated option.

I am using the .bat file... I've also tried the toolkit, and both appear to use the same basic procedure, and they stop at "writing system" no matter what.
Does anyone happen to know how the .bat file and toolkit get access to the phone? ...because I can't see it in adb (I'm guessing it's because I can't boot the phone.) However I can get into fastboot and recovery modes on the device.
I cannot get the device (nexus 4) to boot or connect in ADB mode to my computer. What can I do??
UPDATE - PROBLEM FIXED
I un-bricked my phone
SOLUTION this is what worked for me, your mileage may vary
Install ADB drivers, etc. from Android SDK (google how to do this)
Flash custom recovery (can be done easily with Nexus 4 Toolkit here on XDA) - I used TWRP Touch Recovery.
Once that is done, shut the phone off completely and boot into Fastboot (hold volume down and power)
Use volume keys to select Recovery Mode, then hit Power
In recovery mode:
Wipe > Advanced Wipe > Check off the box beside "System" > Swipe to Wipe
Go back to recovery mode main screen:
Wipe > Format Data > Follow the instructions on the screen
I think this step is what did it. When having problems with partitions, just format everything and start over
Now we should be able to write to the System partition, meaning you can flash a ROM and get your phone to boot again.
Follow the rest of these instructions to quickly flash the stock Android image from Google onto your phone.
Go back to recovery mode main screen, once again:
Reboot > Bootloader > Follow any additional instructions it gives you
Download Google Nexus 4 factory stock image "occam" (Google it)
When that is downloaded, open it with 7zip. Inside there are some files, one of which is called image-occam-jdq39.zip. Inside are some images - unzip those as well. You'll need the system.img file in a bit...
Using Wug's Nexus Root Toolkit (Google it - install it on your Windows PC):
Open the program
Launch advanced utilities
Hit the System button to permanently flash to System partition. Hit "ok" on the window that pops up.
Find the system.img file I mentioned back on step 10 and select that, when prompted, and open it.
If all went well, your device will now boot into the stock Android ROM.

Stuck, but working
I was flashing the 4.3 image using the included flash-all.bat (but I edited it to remove -w parameter so that it wouldn't wipe my data).
In the 'writing system' step, the command window got stuck. In the phone screen, at the bottom, it said 'writing' for a while and then that also went away. I waited for ~40 min, and still the command window was at 'writing system', so I closed the command window, and booted my phone by selecting start from the bootloader.
And voila! It worked. Booted in under a minute, the flash was a success, I got JB 4.3 without losing any of my data.
Lost my root and custom recovery though. But I knew that would happen. Gonna try SuperSu for 4.3 now, after flashing TWRP.
Had the same problem, tried everything! With my tiny powers, but it kept stucking at "writing system" . I thought that I bricked the device, so for the last hope, I installed WugFresh's Nexus Toolkit and did a Fast Stock + unroot. It Installed everything flawlessly! I'm gonna donate to that guy! He's a godsend savior.

Stuck on TWRP without a system to boot to.

Hi, I wanted to return my g2 to stock rom because I didn't like my custom rom, so I followed the lg flash tool guide(tot):http://forum.xda-developers.com/showthread.php?t=2432476
It worked, but it was jelly bean 4.2 instead of Kit kat 4.4, so I tried to install TWRP so that I can install again a custom rom, but when I tried to backup before flashing TWRP, it wrote "backup Failed", I tried again and it wrote it again, but then the phone just stayed on the boot animation for a few seconds and didnt turn on again. After that, again I tried to do the flash tool method just to return to stock rom but now, it just doesn't work, whenever I insert the DLL and TOT file and start the installation, it goes up to 80% extremely quick and just boots up to TWRP without actually installing the stock rom. So now I'm stuck here with TWRP but without a system to boot to and no rom on my sd card to flash.
I really need help here because I have no idea how to continue.
Thanks for any help!

You could load the zip you want to flash to a USB drive, then connect it to your phone with an OTG cable. TWRP can read from OTG.
Can you get into download mode? (phone off, hold up volume, insert USB cable connected to computer)

Can you get ADB connectivity from within TWRP if you connect your device to the PC?
If so you could do the following command from your computer.
Code:
adb push ROM.zip /sdcard/Download/
Then navigate to your /sdcard/Download folder and flash the ROM.

TWRP should detect your phone without the need for ADB sideload.
If I boot into TWRP, I can instantly run "adb devices" from the terminal my phone is picked up as a "device".
If I choose ADB Sideload, my TWRP hangs just like yours does, but if I run another "adb devices" command my device shows up in sideload mode, regardless of it hanging.
Conclusion, try running the adb commands without running sideload in the first place.
Edit: Upon reflection, this is most likely because I have created an RSA key between the PC and my phone.

re-installing stock recovery on Nexus 6P

I installed TWRP custom recovery on my Nexus 6P. I was able to boot into it ONCE. When i next tried to enter Recovery, i get a screen showing the Android Robot and the following statement: NO COMMAND
I tried to re-install TWRP using adb twice, but the result is the same.
How can i either fix TWRP, or re-install the stock recovery
I am basically a beginner here, so any help would be appreciated
If you installed the stock system image and then booted into it, it likely automatically reinstalled stock recovery also. I don't know why it does that, but it does. This is why I usually just reinstall TWRP again after each monthly update is completed.
You should use fastboot to install the images, not adb. The command should look like:
fastboot flash recovery twrp.img
I think i just worded it wrong - I used the above command (fastboot flash recovery twrp.img) to install twrp, and then, when i couldn't get back into recovery (Power - Volume Up combo just lest to screen that stated "No Command".), i used the fastboot flash recovery twrp.imp twice to try to re-install TWRP, but it didn't work
I also downloaded the latest stock Oreo ROM, copied the recovery.img file, and used fastboot.flash.recovery.img to try to re-install the stock recovery, but that didn't work either
The once time that TWRP work, it asked it I wanted to use TWRP is read only, to twice i selected NO (don't know if this matters)
Any other suggestions to fix TWPR, or re-install the stock recovery image???
When you say it didn't work, can you expand on that? Was there an error or anything?

If you want TWRP to stick, you need to flash either SuperSU or magisk. The Android with the exclamation mark is what stock recovery looks like.
Once you have TWRP installed and wish to keep it, you don't need to flash stock recovery in the monthly update. Just boot into TWRP after flashing update and root again.
