Hello,
After rooting the system I tried to upgrade the stock firmware.
I probably did something wrong because now the device won't boot.
At startup it shows the "Nubia... Powered by android" screen and does not continue with the boot process.
I still have access to TWRP so I tried to wipe everything and to install the ROM from TWRP.
It looks as if the ROM is installed correctly, but it requires reboot and after reboot the same "Nubia... Powered by android" screen comes up.
I also tried the emergency recovery but that installs only from external sd card (that the Z17 lite does not have), or from OTG device. I connected a USB thumb drive with OTG cable but it doesn't recognize it
At this point I have no idea what else to do.
I'd be happy for any assistance.
TIA

UPDATE: I tried different USB drives. One of them mounted. I found that this one was formatted in FAT. Since this is a small 2Gb drive that cannot hold the ROM, I found another drive that was formatted in ExFAT that also loaded correctly.
I loaded the ROM as suggested and now the phone is working again.
My guess is that the phone can't read NTFS file format in emergency recovery mode.

Hi guys,
I am seriously in agony!
I am new to Android so I am not very well around with adb...
First thing first, I accidently wiped internal storage, my rom and everything....
now i am stuck in recovery (TWRP) and fastboot and want to know if there is anyway i can install a rom or send the rom file to my phone...
Right now my phone seems to be not recoginized by the computer.
Please where do i start? Really appreciate your help!
(hope we had an external hard drive - it wouldn't have been such a big deal..)
You are going to have to use fast boot to flash you system.IMG and boot.IMG into place. Use this guide found in the stickies above your post.

You don't necessarily have to flash back factory stock system image. You can send the rom file directly to the internal storage of the device by using ADB or ADB sideload while in TWRP.
Never tried it, but I see it in the TWRP menu ("external storage") - put your ROM file on a USB key and attach to the N7 with an OTG cable.
The above respondent's suggestion (adb) will also work too. Paradoxically, Windows seems to be the most difficult platform to get this done, especially Windows 8.

Update 3-25-2012
I tried this with an older version of TWRP (2.4.1.0) and it worked just fine. 8 GB USB uSD card in a card reader on an OTG cable - VFAT formatting, no other partitions present
cheers

Yup, this guy helped me out with my issue. Get a flash drive and get an OTG cable (you can get it here http://www.amazon.com/eForCity-Micr...=1364349138&sr=1-3&keywords=otg+cable+nexus+7 for a buck and a half, free shipping. Download cyanogenmod on it, then go to install from fastboot, then select install from external storage, and install the mod. Voilà.

Hi there,
So I did something really stupid and I wiped my phone while in recover mode trying to install a new ROM. And now I'm stuck with a useless phone that can only go into TWRP and Firmware Update Mode.
I've tried every method to unbrick my phone, and have a previous thread on this forum trying to get help (http://forum.xda-developers.com/showthread.php?p=48914581#post48914581), but nothing is working.
My question now is I'm running TWRP 6.3.2.2, If I buy a USB OTG cable and put my rom files on a USB thumbdrive, can I then install the rom from the usb? If so, where in the filesystem does this usb storage show up?

I believe only TWRP 2.6.3.4 can support OTG (I've been happy with it).
I think you may have to ADB push the files from PC over while in recovery (may need to look around).
I stupidly wiped everything before trying to sell my phone, i was unaware that it would remove the ROM. When i try to turn on the device i get stuck at the LG logo, and when i try to load a ROM using my flashdrive and an OTG cable, in TWRP it says 0MB for OTG. ADB in TWRP isnt working either, i have no more options. Please help im supposed to meet the guy in an hour and a half.

I tried flash rom in sdcard by twrp but failed and /persdata mounting error. Then tried to flash rom with odin but the pc not recognized my tablet: either in download mode or twrp recovery, when connect it to laptop there are no reactions, no usb notification, no device in control panel, no driver downloading attemp odin/kies/adb/smart switch did not react anything, just "plz connect your device...". I have install samsung usb driver, i also try to reinstall it multiple times with kies and smart switch but it not work. I have try 2 different laptops (i cant access desktop now) with multiple ports and usb cables, the s7 edge with same port and cable is connect fine so i think the cause is my tablet (my fault
). I dont know what to do now, plz help.

You need to install the Samsung USB drivers first.
Have you tried restoring your TWRP backup?

i have install it already, i also try to reinstall it multipletime with kies and smart switch but it not work. i dont back up by twrp and when i click to the restore page there nothing
i made the boneheaded mistake of deleting everything off my phone in twrp (3.2.1-0) and ive had little success in trying to recover it.
1. my pc will not recognize it when its plugged in, this was also an issue when it had an os on it. ive tried to install the google usb drivers as well as the hisuite drivers with no success
2. i bought a usb otg adapter so i could possibly push the new os through there but when ever i try i get 0mb when trying to select the storage in the mount section of twrp. ive also tried reformatting the usb multiple times but that didnt work either.
3. there is no connectivity while in fastboot as well as adb
I'm caught in a tight situation and don't have the means to buy a new phone if anyone could help me out i would greatly appreciate it

Powerdown your phone and boot to bootloader by pressing powerkey and holding vol- then connect to your computer you should see the Nexus 6p on your pc and. from your computer download any rom of your like,gapps,root optional and copy it to your internal storage. Then just flash.

that doesnt work either. i have all of the appropriate drivers and still nothing.
That could be your pc. Try a different port or even better another pc.
