Bricked Device Help

Hello, my OPO device was bricked after I accidentally wiped the internal memory and it has no rom installed either. However, I have access to the fastboot mode and also TWRP. I've tried to use adb push to put in a rom but it says device not found when I try. Also while connected to my computer, the device doesn't show up, but in device manager it will show up as just "One".
When typing adb devices, nothing shows up, when typing fastboot devices my phone's ID will show with fastboot to the right.

You can do a couple things:
1. Flash COS12.1 from here via instructions in the linked thread
2. Download TWRP and flash it via fastboot commands, reboot to recovery and transfer a nightly and gapps and flash
You are not bricked at all, last time I managed to brick my phone the screen was black no matter what I did, you can easily get back from fastboot

I can't transfer files into the phone as windows doesn't recognize the device anymore, and there is no device found when I try to use adb to push files into /sdcard/
I will try the first option and will let you know.
Edit: First option worked, phone is working fine now. Thanks for your help and I'll be more careful in the future.

Twrp also has USB-OTG function .. Even if you don't have any ROM on phone .. You can download a rom to a usb pendrive and connect it to phone twrp will recognize the USB pendrice and then can install rom from that ..

Flashed stock recovery and thought I soft bricked my shield tablet.

First I'll give credit where it is due. From two threads on this site is where I got help with this issue:
I followed THIS guys steps for manually erasing and got the recovery images and lots of other useful information from HERE. Thank you guys very much!
OK, so, hopefully I can help someone with my little story as well. I was having issues with apps and programs crashing on me with lollipop and the new marshmallow update. The tablet just wasn't working properly and moving slow. I even had the SD card holding all my apps and larger files so I didn't overload the internal storage. So, I decided I wanted to flash back to factory/stock recovery and go from there. I did this using THIS method. I flashed via the "flash-all.bat" file (the command in fastboot is the same as the file name). I should note that there was one instance that failed during the install (I did try it again and got the same failure). Said something about “did you mean you wanted to flash this partition” or something, then showed it failed. After flashing I hit continue on the bootloader screen of the tablet and it said it was "cold booting." After about 5 minutes or so it started to boot but never made it past the NVidia screen. I tried wiping the phone with factory reset, wiping the cache, etc. and then re-flashing the recovery (again with the .bat file). I tried flashing TWRP but it didn't install apparently, because it still went to factory recovery. I even re-locked and then unlocked my bootloader to see if that would set everything straight. Nothing seemed to work. I knew I would eventually find a solution though so I kept looking. Stumbled on some other people that had the same issues but no solution (hope those people got it figured out). So here's what I did after some more research:
First, if you're in this situation and you did factory reset to try and resolve the problem, you may feel like you can no longer communicate with the device via fastboot/adb, but as long as you have the usb drive and your SDK tools installed (I used CodeWorks for Android all-in-one program) that shouldn't be a problem. You'll just have to be in the bootloader on the tablet.
-If for some reason you deleted or uninstalled your drivers and tools you'll have to download them again and then, the computer should still be able to communicate with the tablet. In the device manager under portable devices it will still show up as Module something or other. So the computer still sees the device but doesn't fully recognize it yet. Don't worry, this should still work! Just make sure you that fastboot is seeing the device by inputting "fastboot devices" in the command window and a 14 digit serial number should pop up. If it just says "list of devices" or there's nothing then you wont be communicating with the tablet.
Your device should be connected to your computer and started in bootloader mode. On your computer you should have the command prompt for adb/fastboot open. I just go to the folder where the .exe files are located and hold shift and right click in the white space of the folder, then select "open command window here."
From here follow the erase steps: stolen from manigault! :highfive:
fastboot erase system
fastboot erase userdata
fastboot erase boot
fastboot erase recovery
fastboot erase cache
Then flash your recovery MANUALLY:
fastboot flash recovery {dir}/recovery.img
fastboot flash boot {dir}/boot.img
fastboot flash system {dir}/system.img
fastboot flash userdata {dir}/userdata.img
fastboot flash staging {dir}/blob
fastboot flash dtb {dir}/tegra124-tn8-p1761-1270-a04-e-battery.dtb
You can download whatever recovery version you wish. I downloaded 2.2.2 because that's what my device came with out of the box on Christmas 2014. It will more then likely be a .zip file. To make this whole process a little easier simply extract the files in the .zip file where the adb.exe and fastboot.exe files are located (folder should be named platform-tools) and you can completely eliminate typing the whole directory before the file name. ***After your done flashing everything you can go back and delete those files if you want. Just double check that you're deleting the right files by looking at the original zip file. Not sure if it makes a difference but I deleted them anyway.
For example the commands in fastboot will look like this exactly :
(after extracting recovery files into platform-tools folder)
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash userdata userdata.img
fastboot flash staging blob
fastboot flash dtb tegra124-tn8-p1761-1270-a04-e-battery.dtb
Note: Do NOT use the flash-all.bat command as this doesn't seem to work for this situation. Do it manually like shown above. And let each individual process complete before attempting to input another command.
After this step I didn't select continue on the bootloader. You can either select reboot or simply input "fastboot reboot" into the command window. It may take about 5 minutes to start installing everything but just be patient, it should start. Sometimes with these things you have to do things twice before it works. If for some reason it doesn't work the first time then start from the beginning and try it again. It took two times for me, but that's because I installed system.img twice and was getting double screen. Newb error... and I was a bit inebriated last night when I did this.
Hope this helps someone!
Thanks again to manigault and MidgetMob!
NVIDIA download files HERE!

i think i done the same thing
but the problem i now have is i cnt get tablet into fastboot on pc. i can load fastboot on tablet with power and volume down , but the tablet only shows as MTP device in device manager. i have downloaded drivers from nvidia and no matter what i try i cant install them i have been through all instructions but scince it went to mtp device i cant get device showing in adb. The only way i can get device showing in adb on pc ist to select apply update from adb ! but none of these commands listed in your post will work because its in sideload. is there anyway i cn reset , flash custom rom ect bu using commands while device is in adb sideload.
all i get is now send the package you want to apply to the device with "adb sideload <filename>".....
if you could shed any light on this it would be much appreciated , thanks , lester

did you update official android 6.0 before? then, not working stock recovery, stock boot...
If you can enter bootloader mode, download unofficial twrp 3.0.0.0 (here http://forum.xda-developers.com/shield-tablet/development/wip-twrp-2-8-0-1-unofficial-t2877117) and flash it.
i have a working boot.img file on marshmallow if you want.. please reply.

Sorry for the late response! I have no clue how you got into sideload??? Are you talking about through the recovery on your device? You're not able to get adb/ fastboot to recognize the device, right? It doesn't matter how you get the tablet into the bootloader. Whenever you have the phone in the bootloader then you'll use the fastboot command to "talk to" the device; i.e. "fastboot devices" without the quotes. That command should show your device if it shows as an MTP device whenever you open your "device manager" in windows. That's the same exact situation I was in. Download the codeworks from nvidia like I linked above. Hopefully then you should be able to recognize your device through the bootloader. If not DM me and I'll try to help you.

I'm having the exact problem as Lester. Tablet boots into bootloader but won't connect to computer. So I go into recovery mode and nothing works except apply update from adb. Which brings up the side load message that Lester quoted. And bootloader is showing "device=locked". I am attempting to fix this tablet for a friend that messed it up trying to flash a custom rom. Problem is he had no idea what he was doing and I'm not exactly sure what he did. I do however have a lot of experience with rooted android devices and flashing so any help would be GREATLY APPRECIATED!

Also, I've already tried flashing stock rom back onto the tablet by applying update from sd card function in the recovery but when I try to do that the tablet for some reason can't mount the sd card.

If you've got the device in bootloader then you need to use fastboot, not adb. Try the command 'fastboot devices' and see if the device id is listed. If so then grab a factory image, unzip it and use fastboot to flash the .img files using the commands 'fastboot flash system system.img'. Just make sure to match the partition names to the files.

Hello i have similar issue except when i try flash something i get this error ''remote: file write failed''
and i have to reboot into fastboot to get it flashing fully
but even though i managed to flash everything by rebooting when i boot system nothing shows up, i can just see the back light coming on and turning off after a while
Please help

No OS... TWRP won't display files on otg/sd

I had a bit of a problem with CM and it kept saying trebuchet had stopped working. (This is after the phone had been running fine for a whole year with CM. Then the phone kept restarting and saying trebuchet had stopped working and it would constantly restart until it calmed down. I decided to install and alternative launcher but the problem didn't totally go.
Thereafter I decided to delete trebuchet from root and boom the phone never calmed down and kept restarting. Eventually I tried restoring factor settings and it says now that there's no OS.
I had TWRP installed before but now when I've tried to install the latest one, it doesn't show any files on the OTG. I've put twrp on the SD along with a rom as well but nothing shows at all.
Can someone help in simple terms?

Use adb commands to flash TWRP (Put your TWRP image in the same folder on your pc as your adb and enter each command separately):
adb reboot bootloader
fastboot flash recovery twrp.img (latest version is 3.1.1-0-peregrine, remame it to twrp.img - if that doesn't work rename twrp to recovery.img and try that).
fastboot reboot
If that works, restore you last known good working backup or try re-installing your stock rom.

Install or re-install your Motorola Device Manager on your pc from this link: https://mobilesupport.lenovo.com/us/en/solution/MS88481
Check in your pc Device Manager to see if your device is connected and recognized properly when you plug in the USB cable.
In the folder where your adb and fastboot files are, open a command prompt and enter adb devices to see if the phone is recognized now in adb. If it is, proceed as suggested earlier.

Go to this link (https://forum.xda-developers.com/moto-g/4g-development/rom-stock-motorola-4g-lollipop-rom-t3142816) and download the correct untouched rom for your phone model and transfer it to your sd card or internal memory.
Then try this command: fastboot boot recovery.img or fastboot boot twrp.img
and follow the directions exactly in the op in that thread to flash the rom.

Absolutely no idea how but I managed to get one of the CM roms sideloaded and even though when i chose to reboot it said no OS. I've got it going, however I've forgotten to put gapps on so I'll try that now. Later on I'll try sideload stock rom or something and see how that goes. Thanks for the help so far! :good:

The problem with CM roms is they're not really being updated anymore - just one of the problems I have with a lot of custom roms besides the bugs, etc., etc.
If you're hell bent on a custom rom, I would check out this one: [ROM][OFFICIAL][Peregrine][7.X] LineageOS 14.1 at https://forum.xda-developers.com/moto-g/4g-development/rom-cyanogenmod-14-0-t3469103
Lineage is the new go-to from CM. I personally would go back to stock first, however, to ensure everything is restored properly before installing it.
It's being updated regularly currently.

I just had a old CM rom downloaded from before hence I went to that lol. I'm trying lineage for now but I've also downloads the stock ROM. Whatever will keep the phone going

bricked shield?

hi guys,
i my shield is stuck on the nvidia logo when booting normally, if it brings up the bootloader, it shows unlocked but hitting continue caused it to freeze on the screen, recovery freezes on nvidia logo and fastboot protocol just brings it back to this screen. i orginally installed twrp and it confirmed successful flash of new os .... on reboot it bricked to its now state, i cant get into twrp or get my pc to see it to install a new copy
anyone got any ideas
thanks

@Fairmax don't click continue, it freezes because there is nothing to continue to, as long as you can enter bootloader your device isn't fully bricked. So, to fix your problem you will have to download official ROM from nvidia's site (https://developer.nvidia.com/shield-open-source find your model and click recovery images).
When you download latest ROM unzip it and follow the textual guide, but, there will be one file missing (i can't remember which one, user data maybe or something like that), don't worry and just continue with the next step. After you flash just reboot to system by holding power button. Good luck !

i cant seem to get it to be recognised by windows all i get is this-- Windows has stopped this device because it has reported problems. (Code 43) A request for the USB device descriptor failed.--
trying to install nvidia usb driver via have disk bring up an error that the file is not usable with x64 system

ok after many driver reinstall iv got device manager to say android adb interface but still not showing on on device list in cmd

Well of course adb devices shows no devices because you are not actually in adb mode, you are in the bootloader mode. Just download minimal fastboot and adb, install it and extract recovery image into the folder where you installed minimal adb and fastboot (you don't need any other drivers).After you did this and your device is in bootloader and connected, click on the path in your fastboot & adb folder and delete everything and type cmd. No need to do adb devices, just proceed with fastboot flash ...

good news after a few hours of trying (usb dropped connection a few times then battery died) it finally works again .....been over 2 years since iv had this shield running after nvidia did the recall , now goto put a different rom on there so it dosnt update and kill itself

Hello I had a similar issue with my k1 tablet and ended up flashing factory images via adb fastboot and all flashed fine. Now my tablet is stuck on the boot screen with the green and white nvidia logo. How long does it take to boot please?

I have same issue too. I can load TWRP and flash the other partitions but TWRP shows un-mountable partitions and even a full stock ROM flash will not allow it to boot. I have a similar issue with a recall tablet. what did you do to fix it?

stuck at bootloader , No OS No Recovery :(

hi my oneplus 7 pro 1910 stuck at bootloader and when i press start or recovery it gets back to the bootloader screen i cant even turn off the phone
i accidentally wiped all partitions in twrp and made a format .
anyhelp ? ive tried to do the fastboot rom flash but my pc doesnt detect my phone
i tried almost every solution i found but nothing works

Your bootloader needs to be unlocked to use a fastboot ROM.
Is it unlocked?

Yes it’s unlocked , any help

Search on the fast boot rom thread for the fast boot rom version you were last on, i have used this many times and it worked.
One thing to note, after it flashed everything , I ended up in crash dump error. I went into stock recovery and wiped/formatted my device and it boot up great.

https://forum.xda-developers.com/t/msm-tool-guac-for-all.3934691/ - just follow this guide

One thing that worked for me is when your phone is plugged into your pc open a command prompt and type fastboot boot twrp-*.img (make sure it is the .img not .zip), and from there download the twrp installer .zip and flash that, reboot to recovery, and install the OTA for your device (OTAs can be found at this thread).
If it fails to boot and gives you an error, try fastboot getvar all to see which slot is currently active then do fastboot --set-active=*inactive slot letter* then fastboot --set-active=*original active slot letter* then try to boot to the twrp .img from fastboot again. If fastboot doesn't detect your device at all, try seeing if adb devices outputs anything, and if it does type adb reboot bootloader
