[Q] Need help after accidentally wiping OS and Internal Storage.

Hey Xda, so I ran into a little problem earlier today.
After creating a backup on my PC with the nexus 4 root toolkit and rotting and flashing TWRP I attempted to install a rom but since it was my first time using TWRP (Im used to CWM) i accedently wiped my internal storage and my OS and now im stuck in TWRP since i have no OS to boot to.
Is there anything I can do or is all hope lost?
Thanks in advance

Yes, install adb platform-tools and push a rom to the sdcard: adb push namerom.zip /sdcard/. Or try TWRP sideload http://teamw.in/ADBSideload.

Dude the same thing happened to me the very first time but here's what I did I hooked up my phone to the PC and ran wug nexus tool kit and performed back to stock. And it worked like a charm hope that helps if you're still stuck there:thumbup:

I tend to take a FAT32-formatted flash drive, USB OTG cable, throw a custom ROM, Kernel, and Gapps onto the flash drive's root, reboot the tablet to TWRP, wipe everything (except USB OTG) and format data, reboot back to recovery, and then install ROM, Gapps, and Kernel (in that order).
In other words, if you have a flash drive and OTG cable, you can recover your device pretty easily If you don't have these though, you can adb push the zip's over to /sdcard I believe; it's been awhile since I've done this.
If you want to go back to factory stock, you can grab the latest factory image from the link shimp208 provided, and should be able to run the flash-all.bat included (may have to have platform-tools in PATH if running Windows, or cd into the folder).

Edit: I'm not entirely sure how USB OTG is on the N4 though. If it doesn't work, then adb push should be fine.

Interesting, This is indeed a truly "clean install". Any idea if this method would this work in CWM. Sorry to OP for jacking your thread.

I myself have done this before, I hope you get through it. Goodluck

[Q] "No os installed" Help!

i have tried to install a custom rom on my nexus but failed as when i meant to factory reset i deleted everything from my sd card (internal memory) so all i have is TWRP (team win recovery project) and fastboot and nothing else. also i cannot connect my nexus to my pc so i cant flash a new rom on to the device. PLEASE some one help me!

Did you make a backup? You can also use any of the multiple toolkits available to you to reload the stock ROM. Also, questions should be in the QA section to avoid clutter.

i always use this method to flash roms as it cuts the hassel of copying the rom into the device for flashing and its very easy actually......just Follow these Steps.. :fingers-crossed:
Download Wug' Nexus Toolkit
Install it and Boot your device into TWRP recovery
Now (assuming that you have Proper Nexus 7 drivers) Open the Toolkit and connect you device to the PC.
Now click the launch button under "Advanced Utilities"
On your device click advanced and the ADB Sideload.
Check mark Wipe Dalvik Cache and Wipe Cache and Swipe to start Sideload.
Now on your PC, click 'sideload update' under "ADB Sideload Update".
Click ok in the next pop-up and now Browse to the custom Rom that you want to flash.
The rom will be uploaded to your device temporarily for flashing and then it will be DELETED once it is Flashed.
This can take upto 30minutes depending on your computer's SPEED.
The rom will be flashed and the device will boot up.
I AM NOT RESPONSIBLE IF YOUR DEVICE BREAKS, OVER HEATS, OR YOU SPILL COFFEE ON IT. DO THIS AT YOUR OWN RISK..!!!
HIT THANKS IF I HELPED...

Cuts the hassel of copying the rom into the device... how hard is it to copy a zip file from your computers download folder to your device download folder? I found it to be much easier to have all my flashables on my device for reflashing with MultiRom without the need of my computer. The majority of the time just flashing the ROM will not be sufficient; flashing gapps and patches is also needed for it to work properly. And I think it would be extremely concerning if it took up to 30 minutes, even if the computer used was USB 1 with 3400 RPM IDE hard drive. It would not be possible to use a toolkit as his device is unrecognized by his computer, does not have the proper ADB interface driver needed to interact with the toolkit and does not have USB debugging enabled.

This wouldn't help at all considering that it looks like OP panicked and did a full internal wipe.
OP, if you have TWRP working I would suggest booting into TWRP, going to Advanced > ADB sideload and then find the ROM zip you were trying to install, then open up command prompt and use adb sideload <path-to-zip> (how exactly you go about doing this last step depends on where you get adb-- any of the previously linked toolkits should include an adb.exe file though that you can run).

D801 (Tmobile) Stuck in TWRP - No OS Boot

This isn't my phone. It was just running the stock OS with root. I think what happened is that an update from tmobile was released, and got installed, which corrupted the ROM/OS. The only backup it has is a couple of months old. I've tried wiping data/system/caches and factory resets which did not work. I've also tried restoring from the backup; just system, then both data and system, and no results.
Currently it has no ROM on it that I can install.
No matter what I do it always reboots back to TWRP. It has TWRP 2.6.3.2
I've tried to mount the SD card from the Mount menu so I can push a ROM to it, which doesn't work.
I've tried using ADB sideload but it doesn't seem to start, and I'm not able to see the device from command line with 'adb devices'
I've tried using the LG PC Suite, but it also cannot detect the device.
Please help, thanks!

you said you see no adb devices, this usually means the adb drivers are not installed. no adb drivers = no sideload. also make sure you are in twrp when you are trying to use adb. also i'd recommend updating to twrp 2.6.3.3 from the official twrp site, it's much better than 2.6.3.2. also if you are using an outdated adb.exe that will give you adb problems. can get the latest from android website.

Well, I have no way to transfer any files to the phone, so I can't install the new recovery. All I need to do is be able to push a ROM file to the phone, I think, so I can install it.
I am using adb sideload from recovery. I'm not aware of another location to do so. It just sits at the prompt saying starting sideload...

that's because you have no adb connection. no connection = no pushing files. that's why i said you need to get adb working first.

I installed the universal adb driver and now 'adb devices' does show the device, and I'm transferring the ROM with adb sideload 'filename', so hopefully this will work.
Thanks!

Okay I got the ROM transferred and I have installed it successfully.
Using this one: http://forum.xda-developers.com/showthread.php?t=2598361
But when I reboot it goes straight to recovery.
A factory reset fails. I'm only able to advanced wipe of system/data, also it fails when I wipe cache or dalvik.
So I've tried wiping system/data, then installing the ROM again, and it just reboots straight back to recovery.

I sideloaded TWRP 2.6.3.5 for tmobile. Verified it shows 2.6.3.5 TWRP now. I'll try to sideload/install the ROM again.
Edit: When trying to factory reset it says failed to mount cache.

Okay so I have successfully installed the ROM with TWRP 2.6.3.5 and when I reboot it still goes straight into recovery.
What next?
Thanks
Edit: Is there perhaps something wrong with the bootloader, or what? I'm thinking part of the issue is because I can't mount or wipe cache/dalvik?

I'm in the exact same position with the d800. Stuck in twrp. I think we need to sideload a working boot.img. Idk. I was working on it all night reading everything I could about adb because although I had the lg drivers and my PC recognized my phone was connected it would give me a driver error. Thus I couldn't use the flash tool. Can you get to download mode?

How do you start download mode?
I was able to mount cache now, after unchecking format setting (use rm instead of -rf), but after doing factory reset and advanced wipe (everything except internal storage), then installing ROM, it still reboots straight back into recovery. Damn.

Any luck? I tried flashing CM11 on TWRP 2.6.3.2 (per XDA instructions) and it failed. Now I am stuck in recovery and can't ADB new recovery

[Q] Help Please!

Hey guys! I'm not a developer. I unlocked the bootloader of my Nexus 4 and rooted it. Along with that i even installed a matrix kernel. So now what happened is my phone wouldn't display anything after starting up but it was connecting to my PC as i had enabled USB debugging mode. But as the phone wasn't starting, i formatted everything except the sd card, cleared the cache and dalvik cache and reinstalled the franco kernel. Even that didn't start so i downloaded CM 11 nightly version and tried to install it, but it didn't get installed. I installed the matrix kernel again and tried to install CM 11 but even then it didn't get installed. Now my phone is stuck on the google logo and the only thing i can do is go to the bootloader, recovery etc. but I can't connect it to my PC as i had factory reset it, the USB debugging had stopped. Basically i just need help in figuring out what should i do. I'm ready to have my phone back to its stock settings and i'm even ready to keep my phone rooted. I just need a way for it to start working. Please guys!! Some help here!!

Don't panic. The first thing you need to do is flash the factory image in fastboot. After you get your phone back then you need to read a lot before you flash anything again

Relax!
Download the Nexus 4 factory image from Google and flash it using fastboot from your PC.
This will revert the phone to pure stock unrooted settings and then just try rooting the phone again from there.
Check of your kernel and ROM files were proper, if they were corrupted then it could have lead to the bootloop

And by the way, I downloaded CM11 Nightly but it couln't get installed due to some error and before installing the ROM i installed the matrix kernel but after installing, the phone didn't start. It showed the starting animation but did not start the phone up. Can you please tell me how to enable USB Debugging from CWM Recovery? Coz it's stuck on the Google logo and i can't start it, so neither can I enable the USB debugging mode.

Is your recovery up to date? If not please flash the latest one or flash trwp recovery instead. Use adb sideload, since you cant access your usb debugging

You don't need USB debugging for fastboot. Download the factory stuff from google, turn off device, hold volume down and boot up device (i.e. into bootloader), and run the "flash-all.bat" (after extracting the downloaded file) .. This will wipe your data. If you want to keep data, open the flash-all.bat file and remove the "-w" from the last line.

Boot into bootloader (hold power and system on), flash the though recovery through adb, mount your .zip,, flash your .zip through recovery. Sorry if that doesn't make sense, I've been drinking with the roommates, lol.

The same thing happened to me also! The whole /data (incl. sdcard) partition went corrupt (showed up in TWRP as eemc instead of ext4) & the /vendor failed to mount.
First I had to repair the /data partition (unfortunately the data was lost, as it repaired to a blank partition). I ended up having to go home (was at work at the time) & hook the phone up to the PC & download the ROM & transfer it onto the sdcard. I'm not entirely sure why/how this happened, but I believe it was because a corrupt vendor IMG. Although that theory doesnt include why the /data partition corrupted, it only explains why the /vendor partition failed to mount.

Fastboot flash system system.img

I have the same issue. The problem is, that my computer will not recognize the phone in bootloader mode or in recovery mode(MTP enabled). How can install usb drivers without being able to boot into phone OS???? I've tried Nexus Toolkit with no success. Please help?

Have a look here how to load in bootloader, flash, etc.

So I did the same thing. I'm sitting in TWRP right now but have nothing on the phone. Will I be able to reboot from TWRP into the bootloader and just use the flash-all command to get my phone to boot back up, then just go through the process of custom recovery again?
Basically I'm worried about leaving twrp without an OS. I didn't wipe bootloader did I? Also, I tried to download a ROM and just drag it to internal memory, but I can't seem to add anything to the internal memory.

Hi... Just boot into recovery and reflash system.img from the factory image of your choice in bootloader with fastboot. Also flash the vendor image from the same factory image. Done...
Or reflash the whole package with flash all (manually is better imho). But you'll waisted time... Let your phone reboot into Android and you'll have your internal storage back.

Yes TWRP has a reboot to bootloader option available. So you can access fastboot via bootloader to flash the necessary images. Just don't forget to re flash TWRP image again in case the stock recovery image was flashed beforehand.

The odd thing was that I did choose that option to boot to bootloader in twrp and it didn't work. I ended up having to reboot to bootloader manually. Not a big deal. All is working now, but thought that was interesting.

Exactly which partitions did you wipe? system? data? Internal Storage (userdata)? all of the above? Hopefully you did not wipe userdata (all your stuff). Were you on a stock ROM? You should be able to d/l the Google image from the same build you were on, extract system and data and fastboot flash those. Don't flash userdata. All your stuff should be there. Follow the tutorial on how to set up fastboot and selectively flash partitions.
