Hello,
I just got the OTA message for 4.4 and tried to install it but I got a bootloop. After clearing the cache and performing a factory reset in TWRP (which got installed through Nexus Toolkit) it still didn't work. Someone told me to perform a complete format through TWRP which I did (hindsight, I know) and now TWRP says I have no OS installed, adb won't see my device (I have the drivers installed) and when I go into the bootloader (which says FASTBOOT MODE) fastboot still won't recognize the device (nothing shows up on my PC either but that can be normal).
I'm at my wit's end here, is there anyone who can help me?
You need to realize that if you want to install OTA, you need to use stock recovery. Even though it is possible to flash through TWRP, it can still run into problems. Especially when you made root modifications to your device.
You don't have to do a full wipe for everything. There is a method to flash factory firmware without wiping data (link in my signature). After that if it still don't boot due to existing data, boot into a custom recovery and do a factory reset without wiping the internal storage.
But since you have custom recovery already, just go into the Development section, find a stock KitKat rom, download it and sideload it using TWRP (which is enabled it in the Advance menu).

Yes I've tried that but I don't know how to sideload it. adb doesn't see my device, fastboot doesn't either and windows doesn't recognize the device (although I have the adb naked drivers installed).

If it is connected adb should see your device while in TWRP. Fastboot only work in fastboot mode (bootloader screen), not in recoveries. If you have the UND installed then they both should work, if not it wasn't installed correctly. If you are using Windows 8 you need to disable driver signature before you can install UND (search google for that).
You could also make a bootable Ubuntu flashdrive, and use the ADB/Fastboot for Ubuntu link in my signature to install them.

I tried both. ADB devices gives me an empty line and fastboot devices (when in bootloader screen) gives me nothing at all. I've tested 2 different computers (both windows 7 x64) and it still won't detect it. When in TWRP windows tries to detect my device but it says "Unknown Device" and gives the yellow triangle.

You might have to point the drivers to your phone. If you go into device manager, see if your Nexus 4 has an error. If it does, right click it, and then update the driver. Do a manual install, and point it to the .ini file for the driver

Fix your drivers, uninstall them and select the checkbox to delete the driver files, search Google on how to disable driver signature and try reinstalling the driver again.
or
Make a bootable Ubuntu flashdrive, and use the ADB/Fastboot for Ubuntu link in my signature to install them.

I did this and still the same, adb gives an empty list and fastboot gives nothing.

Try using a different cable and on different computers.

I've tried 3 different computers, 2 different OSes and 3 different cables. Nothing seems to work. I'm really starting to panic now.

Just to clarify, see attachment for the correct name of the device if UND is installed correctly.
If you tried it with Ubuntu, make sure you do the 1st step from here also:
http://bernaerts.dyndns.org/linux/74-ubuntu/245-ubuntu-precise-install-android-sdk
Same here
i installed the ota update normally with twrp installed everything went fine but im kind of disappointed in this update:/

These are my findings:
Ubuntu:
- Bootloader (fastboot)
-- running lsusb in Ubuntu shows no device
- TWRP (adb)
-- running lsusb shows no device
Windows 7 (3 different computers)
- Bootloader (fastboot)
-- Windows gives the following popup, no device listed in Device Manager
- TWRP (adb)
-- Windows gives the same popup as on fastboot and this appears in the Device Manager:

Is file transfering working atleast? If it is, then it's a software problem. If it isn't, then it could be a hardware problem, you can try replacing the USB charging board for the phone. Also some roms with corrupt files can cause this issues, so try a different roms if you haven't.
File transfer used to work but atm I'm unable to even connect it to a computer so I can't actually transfer any files. If I could I would flash a rom but no files = no flashing.

Get one of these: http://www.ebay.com/sch/i.html?_nkw=nexus+4+usb+charging+port+replacement&_sacat=0
If it don't work, then use the phone as a door stopper.
hey guys, I'm having the same problem here but with a Nexus 5 now.
Its been over a month and I've kind of gave up over the situation.
I couldn't resist to write a comment on the thread, since it appears to be the same problem as mine.
long story short, I decided to order an USB charging port to replace the one on the phone (as my last attempt).
Otherwise I will consider using the device as a door stopper.

thanks in advance
Hi
I flashed CloudG3 rom under CWM, and after install it won't boot the system - it sends me to CWM recovery instead.
Figured I would install another ROM but my device is not recognised by windows (won't show up under my computer). Can you please guide me on what I could do to sort this?
Thanks
Install the lg g2 drivers to get recognised by the os, after you download driver for adb sideload and restart, run sideload in the recovery with the usb pulgged in ur pc.
Open Android folder, and then do to platform-tools, drag a ROM there to be installed. Open a command in this folder. Write what is in the cellphone, adb sideload romfilename.zip if i'm right, then it will start installing and then you get out of the recovery stuck.
Using TWRP.
Hi
I installed lg drivers but it didn't help - looked like it was CWM that was causing an issue to get the device detected by computer.
Before you posted, I followed the instructions here http://forum.xda-developers.com/showthread.php?t=2739739 - this helped to get TWRP on top of CWM. Under TWRP, the device is detected by windows
Now should I install a rom using your guidance above or can I do it under TWRP? Or is it the same?
A friend of mine rooted my phone for me a while back. He's no longer around and I'm still pretty unfamiliar with the process without using twrp. I'm not sure what method he used. I was going to try flashing a stock os via adb but adb doesn't detect my phone. I'm sure it's a driver issue but I can't seem to fix the problem. I also have trouble transferring files with a USB cable. My computer sees the phone but as far as opening it to explore or transfer files, it doesn't work. I downloaded drivers from a link I saw in another thread on xda and installed some file with a weird format and that didn't fix the problem.
Can somebody please point me in the right direction?
First of all, I'd suggest you to try with a different cable. The one shipped with the RP2 is optimized for power and might cause issues when using it for data trasfer.
Secondly, generally speaking you should install adb platform tools (I don't remember installing specific drivers for the adb, to be honest). You probably want to install the google usb driver as well for the fastboot as well.
If you confirm that those solution do not provide a solution to you, we might look at other causes.
Once everything is workin, you can proceed to update (since you have root permissions, I am assuming you see the OTA but you don't know how to proceed). The procedure that I followed is this:
1. Download razer factory images for mr1
1. perform a nand backup with TWRP
3. extract the factory images somewhere, open the "flash_all.bat/.sh":
3.1. make the fastboot variable point to the actual fastboot executable (if you are not familiar with relative paths, use full path and it will work seamlessly)
3.2 remove/comment the line
Code:
fastboot erase userdata
4. run the script
5. reboot your phone and perform the OTA update
6. install arter12 kernel
7. In magisk installer download the zip and flash it with TWRP
So I've been troubleshooting for the past few hours. I'm familiar with the process that needs to be done. The issue I'm running into now is a driver issue. I deleted the Google driver and installed a Samsung driver just for laughs. I can view my phone and transfer files now flawlessly. But it still isn't detected by adb. I was just going to wipe my phone and reflash the stock rom with adb fastboot. I wonder if there's a way to flash the stock rom with the Razer bootloader until I figure out what's going on with adb?
The google drivers are for fastboot (bootloader), not adb. For adb I just let windows do the automatic install (I'm sorry, I just assumed you are using windows, tell me if that is not the case).
Keeping the assumption that you are using windows, try to uninstall all driver (both from installed apps and from installed driver. For the second step you will need to show in device manager, all hidden devices and uninstall all of them).
Reboot windows and reconnect phone, I'd expect it to be automatically recognized as Razer Phone 2.
As per bootloader, in W10 sometimes it's a pain in the ass installing the drivers as you might need to manually install them.
So it had been a while since I had tried getting into recovery twrp but I figured I could remember how so I did
fastboot flash boot twrp etc.img
This was a mistake according to the site here > https://twrp.me/nokia/nokia6_1.html
WARNING: If you accidently flash TWRP to your device using fastboot instead of temporarily booting the image, you will need to download the latest factory image for your device and reflash the boot image.

Which is exactly what I did
So now my phone is either stuck on the Nokia logo, or I can load twrp.
They provide some info on fixing it but I'm not sure I understand what they are saying. Can anyone help with this?
The phone was running Oreo (not sure which version unfortunately) and it was fully rooted and running magisk/xposed/su just fine before my mistake.
I don't have access to fastboot. Only Twrp and adb commands.
Edit, I can get to fastboot/download mode through the twrp terminal.
[SOLVED]
So I was able to use twrp to copy all of my internal files onto an sd card.
Then I set about getting this tool here > https://github.com/RaghuVarma331/Nokia-Tool the firmware specific to my phone, and modifying the bat file found here > https://github.com/RaghuVarma331/Nokia-Tool/blob/master/batscripts/Nokia-Tool-DRG-B2N-PL2-CTL.bat (because windows for some reason gave me a 16 bit application warning when I tried to use the tool exe)
My phone flashed a bunch of time and I was able to load up an almost entirely stock android 10, still capable of using magisk, edxposed, etc.
And now all there is to do is to get everything back onto it and set up which is at this point, the best case scenario.
So I broke my fastboot drivers by learning about all the subcatagories within driver itself, i.e, abi, android composite, etc... essentially I keep flashing the driver over and over and was somehow able to get my device to post in windows as a directory..
I have two Questions,
1. Theoretically, would it not be possible to use a partition manager on windows to inject a custom bootloader, when the shield posts like this?
2. How would one fix their fastboot driver without factory reseting their computer?
I already went into device manager, uninstalled device, uninstalled driver, rebooted, did many unneeded steps on the shield, nothing worked...
So I just factory reset my PC since that was faster and my drivers installed fine....
Any help or suggestions appreciated!
NOTE:
HOW TO OPEN SHIELD FOLDER ON YOUR PC- BOOT INTO FASTBOOT AND RUN TWRP, WHEN TWRP IS OPEN, YOUR SHIELD WILL POST TO YOUR PC!!! THEN YOU CAN DRAG AND DROP FILES NO CODE!!!
