so you can boot to recovery or bootloader?
try nexus root toolkit - there is an option to unbrick. Wipe everything and try to unbrick.
how windows detects your N7? maybe try different usb cable - if not genuine, then cut a lil bit of plastic, so it goes all the way to the usb port
give some photos of what errors do you have in recovery

I can boot to bootloader and thats it that tool can't write to any partitions thats what I tried in the first place it erased the partitions but then could not write to them so im left with no system no kernel or recovery
Download drivers from here
Open cmd as admin and type fastboot devices, it should detect your n7 with some numbers and letters.
If you have grouper (wifi) n7 then download recovery here
Go to bootloader, connect n7 with pc and type:
fastboot flash recovery twrp.img
Where twrp.img is the name of recovery file you downloaded.
Then type: fastboot reboot
In cmd you probably have to go to proper folder just use cd.. to go up a folder and cd name of the folder to go to proper folder. I use C:\adb as drivers install right there

Do you have a dload folder with update.app inside, in sd card?
With that and pressing vol +, vol - and power at same time you enter in flash mode and start to flash the rom

Hi Have got succeeded or not, if not follow the guide.
Is your phone being detected by PC if yes then you have chances of recovering your phone.
1. Download 15 Seconds ADB and Fastboot Drivers. Visit the official XDA forum for download and installation instructions.
2. Install Huawei HiSuite which will install drivers .
3. If HiSuite doesn't install Install drivers then install universal drivers for your device .
Now connect your device to pc and open HiSuite and click on system recovery it will show options for recovery if it is success then you are fine if not then proceed to this method.
Connect your phone to PC.
Open Command Prompt in the directory where you have extracted the ADB files by holding Shift and Right Mouse Button and finally click Open Command Prompt window here in the context menu.
Completely power off your device.
While holding Volume Down button, connect your device to PC via USB cable to boot to Fastboot Mode.
1. Type the following command in ADB :
Code:
adb devices
If your device is being detected and it shows list of devices attached and its serial number.
2.Now download the firmware of the phone before your phone got bootlooped extract the update using the file here
3.Now copy the following files ( boot.img, recovery.img and system.img ,cust.img ) from the extracted files to the ADB files directory.
4.Now Execute these commands one at a time using the command prompt.
Code:
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img
fastboot flash cust cust.img
fastboot reboot
5.Now Perform a Factory Reset if your phone got recovered.
If not then download the stock recovery of your Device and try steps 2,3,4.
Even if it doesn't get succeeded then try this option .
If your device got bootlooped while on Lollipop or Marshmallow then you have one more way to recover .
6.Now download the latest TWRP from here and boot into TWRP recovery if you cant enter TWRP recovery for this version then try the previous TWRP versions like 2.8.7 ,
7.Use the following command to flash the TWRP recovery
Code:
fastboot flash recovery twrp.img
8.Then download any of the custom ROMs or ask any of the XDA members for TWRP backup for your device and flash them through Recovery.
Then Reboot your Device.
You would most probably recover your device from any of the above methods . I too had the same problem and My device was use less for almost 6 months but after several trial and error methods my device got recovered.

Did you try flashing different variant ROM ie different builds?
Actually I too got the same problem bootlooped on LP but cant flash the LP ROM back so I flashed different Region ROM.
Give a try to TWRP Method It should give you success.
Imp:
Try the previous ROM where you got Bootloop, or the version earlier to it.If it doesn't succeed try the rom which you got initially on your mobile.
PS: If your phone is being detected by your PC you have good chances of recovering your phone.

Files all courupted
With stock recovery you can't use adb sideload in windows 10.
If you're unlocked i would flash Codeworkx TWRP, download the OOS 5.0.1 Full Rom Zip, boot into TWRP, copy the zip to your phone or sideload the zip.
If you're not unlocked (and thus being unable to flash twrp) use windows 7 and sideload the zip.
You can download ADB drivers here
Can you boot? Turn on USB debugging , make sure that you allow the device when booted.
Do an advanced devices when in the OS make sure it's there.
Then you can install a TWRP recovery and do what you need to.

be sure your bootloader is unlocked
turn your phone into fastboot
open command prompt to the folder your twrp is in.
rename the twrp image file to recovery.img
do the following command: fastboot flash recovery recovery.img
after that boot into recovery
press adb sideload
on the computer, open command prompt to the folder where your zip file is in.
rename the rom zip file to rom.zip
do the following command: adb sideload rom.zip
done!
Thanks bro, I shall update you on the situation once I done, at work now.
Do I need to “open command promt “ at my sdk folder/plat-form tools?

Cannot adb to the phone in FASTBOOT. adb devices shows nothing when in FASTBOOT, but shows the device when in normal boot.
Hence I cannot upgrade TWRP from 3.2.1-1 to 3.2.3-0. Was trying this so to upgrade from beta23 to the beta 26, now 27 with which 3.2.1-1 seems to have problems.
A 2nd approach, just re-installing beta23 without Magisk18 gives the stock recovery which manages the beta27 install. But then I'm blocked from a Magisk18 install and still cannot use FASTBOOT mode to put TWRP back on.
Thought the adb drives could be old and sought new drivers, even assuming your link is to the most current I don't know how to get my Windows7 to use the zip file. Can you assist? This would let me put the latest TWRP, hence install Magisk18 and be rooted again!
Hi,
When my S7 Edge boots up it jumps to twrp but it's stuck on the teamwin logo screen and does not advance to menu.
This happened after I tried to format the data partition to ext4 via twrp and it just got stuck there too so when I rebooted it landed in this situation.
Unfortunately reflashing twrp or reflashing the stock rom via ODIN does not work as COM3 is recognized but then when I press start it doesnt do anything....
Also tried the suggestion I read online of:
fastboot format cache
fastboot format userdata
These commands just get stuck on <waiting for device>.
Also tried adb shell recovery --wipe_data but it gets stuck at I:LANG: en
Any help will be much appreciated!
Thanks
This is how I solved it in the end.
With cable connected I did:
1. adb push boot.img /external_sd
2. adb shell
3. dd if=/external_sd/boot.img of=/dev/block/platform/155a0000.ufs/by-name/RECOVERY
4. fastboot format cache
5. fastboot format userdata
6. adb shell recovery --wipe_data
7. adb fastboot recovery
Notes:
The boot.img was obtained from a downloaded stock rom image and by decompressing the AP file (just open it with 7Zip) and then you need to uncompress boot.img.lz4 with 7zip zstandard (look it up)
Step 1 took sometime to run since TWRP was stuck loading using a lot of CPU as phone was really really hot!
Sometime I needed to do a adb fastboot recovery and then quickly run and rerun command in step 1 until it succeeded.
Step 6 is redundant but is there just to be safe.
After this you are booted back to a stock recovery where you can use Odin to flash what you want.
In my case I flashed a stock rom and then flashed TWRP again.

Same problem and question here
Hello guys
I have a problem, yesterday I was putting the twrp to my one plus 6t via fastboot and as soon as I entered the bootloader I put the command "fastboot boot twrp.img" and it said "fastboot unknow command".
So I searched on google for the commands to start the twrp via the PC terminal and I found this command "fastboot flash recovery twrp.img".
Everything ok, it restarts the screen, 3 minutes then it is turned off and remains in the initial screen where it says that the bootloader is unlocked, it does not go in fastboot mode not in recovery
Tips?
Use the Msm tool to recover if your phone is bricked.

When it comes to A/B slot phones (Like the OnePlus 6T), you're not suppose to use the fastboot flash recovery twrp.img command. The reason why is because that command doesn't apply to A/B slotted phones, you need to use the fastboot boot twrp.img command to boot into TWRP and then flash the TWRP flasher for OnePlus 6T which can be found here:
https://forum.xda-developers.com/on...overy-unofficial-twrp-touch-recovery-t3861482
Make sure to download the flasher zip and the latest img for TWRP.
Drag the .img into the fastboot folder and use fastboot boot twrp-3.3.1-8-fajita.img. Then once it boots into TWRP, drag and drop the installer zip onto your phone's storage and flash it. Reboot into recovery and you should have TWRP on your phone.

Make sure the device is off,Press volume up + volume down button then connect it to the computer.
If your device still doesn't show up,try pressing volume up+volume down+power button and then connect it.
This worked for me in many cases.
When I connect my phone via USB it shows up in the device manager as Qualcomm HS-USB.... But when I try using MSM it shows the phone connected on port 16 and I hit start and it fails after 16 seconds because it can't do a download. My question is is the download external via internet or is it a file in the MSM folder? I might be blocked by firewall at work if external.
EDIT: Looks like I found my issue. I couldn't tell if my phone was on or off since I had no display after trying about 20 more times I guess I got it ON.
