I have a Nexus 9 that will not connect to Wifi and will not connect to a PC or MAC. It had been rooted and I had TWRP on it which it used to boot to. Once I installed Cyanogen Mod using a USB and Twrp it now boots but no wifi and no more root. Now I seem to have no recovery either. When I push Power and Vol Down it boots to HBoot and when I select recovery it just goes to fastboot. PC or mac will no longer see it. I tried installing TWRP via downloaded APK which states it needs root access and I installed SuperSU but that keeps saying it needs updates and with no WiFi that is not an option. CM13 comes up but has a message that says "Android System, There's an internal problem with your device" All I have is the ability to read from a USB drive which I can transfer files back to the device on. Does anyone have any suggestions at all?
UPDATE: I did manage to gain root access to TWRP but it's saying custom recovery not installed or not detected. Without Wifi still no way to get. Is there a way I can load that from the USB drive I'm able to connect to the device and copy from?
Thanks
Chris

Hello,
I'm trying to connect my Samsung GS3 to my computer to use with the Android SDK Manager and the ADB console, but when I connect it to my computer it recognizes it as a Camera and ADB doesn't recognize it either, how do I fix this?
I'm locked out of my phone and trying to unlock it using methods from here: http://forum.xda-developers.com/showthread.php?t=2620456. So I have no interaction with my phone beyond the locksreen to change from PTP to MTP as I've seen people with similair problems suggest. Is their a workaround?

Since you're already looking in the right place, consider installing a custom recovery (such as philz) with odin and then flash the zip.
Thanks for the help. I was finally able to get my computer to recognize the GS3 (Installed Samsung USB Drivers from their website instead of Kies). But now after it recognizes that I have new hardware installed, when I try to use the Wizard to automatically install the drivers I get the error: "The required section was not found in the inf", did some searching and realized that this is due to not having the wpdmtp.inf file on your computer. I've checked and it is indeed missing, does anyone now of a way to install this file?
I'm still locked out of my phone. And I don't have an SD Card to install recovery and flash the zip as dxppxd suggested.

Take another shot by booting into a custom recovery, most give you adb access while in recovery.
If the phone is locked with usb debugging disabled you won't be able to get adb access.
Hi folks,
I previously managed to get Cyanagenmod installed on my HTC One X but since made a mess of it trying to get a stock ROM on there (to unlock my SIM). I have since given up on getting a stock ROM back on there and am now trying to get Cyanogenmod back on there, but I have hit some problems.
I have CWM on there and my PC can see the phone in Fastboot, but not via ADB (which I am trying to use to 'push' the ROM on there so I can install it). My PC (Win 8.1) is giving me a "device descriptor request failed" when connecting to USB when on the boot menu, and is showing up just as "One" in device manager when I load CWM. However neither of these situations are allowing my computer or ADB to recognise the SD card.
I have tried 'mounting' it in CWM, updating drivers through device manager, installing Sync (and uninstalling/reinstalling it), installing HTCDriver_4.10.0.001.msi all to no avail.
Does anyone have any advice to get my PC to recognise my phone or otherwise get a customer ROM installed (if there is another way.)
Thanks in advance all.
i have a nexus 5 used to run cm13. now only twrp.
when i wanted to instal a new rom, i deleted the old one(did full wipe, all options avileble in the twrp option), before realesing i had no new rom. i went to my computer to put a new rom on in. the my computer would not find my phone. which it used to do. drivers and everything are up to date. i tested it on multiple computers. even other computer where other nexus 5 did connect on.
since the nexus 5 does not support sd card or otg. so i can not put the file on any other way than trough my computer but since i cant connect it. i was hoping someone might now a way to get the file on my phone
tl;dr
-no rom only twrp
-no computer acces

You can try to install nexus driver...do pc find the nexus in download or recovery mode?
When I "Swipe to wipe" in twrp, twrp instantly resets.
I can not swipe to wipe.
I successfully had rooted access and twrp installed with Slimroms on Nexus 9 running correctly.
I Tried to install an 8.0 Oreo rom but it crashes and resets on the google screen.
when i try to return to old roms I get "Error 7" in Twrp.
and I can no longer swipe to wipe or factory reset.
Anyone know how to fix this issue so I can return to 7.1.2 SlimRoms?
the nexus 9 no longer shows up in windows or under ADB Devices.
So i cant access adb functions.
did my bootloader have a problem?
it seems twrp is crashing when its trying to format or wipe mounts ?
Have you tried flashing the latest firmware from Google with fastboot? That's where I would start.
Sent from my SM-T820 using XDA-Developers Legacy app
Can i do that with only twrp?
Does flashboot require adb access from a pc? I cant seem to get the device to show under windows or adb.
Can i use a memory stick and twrp to install those ?
Ill try tonight if thats possible without pc adb acess.

No, can't do it in TWRP. If you're having trouble, try wugfresh toolkit. It's no longer updated but you can use it to flash a factory image that you download yourself. Toolkit might help with your issue of not being recognized by your PC.
Wugflash cant recognize the device if windows cant also.
I tried.
I can get into twrp and fastboot. But i have no connection to pc, except for usb memory stick.
The device says unlocked inside of fastboot.
Why cant i connect to adb windows? Ive installed usb drivers many times for many different phones and pcs. I dont think thats the problem.

I've had to do it few times to get it to recognize device. That's the only reason I suggested wugs. It has quick options to retry driver install. But manually is better of course. Windows 10 gave me a heck of a time with driver's.
Hello,
I have a big problem and try to solve it now longer than 4 hours...
I have an old phone (HTC Desire Eye) and tried to install Lineage 14.1 but it stucks on the loading screen and did always some virbrations but after >15 min it was still in the loading screen.
So I wiped everything except the twrp recovery system and now I try to copy the lineage-zip and gapps on the storage again but the device is marked as offline! So I can't use the sideload command for example.
I reinstalled all drivers and everything but nothing helped.
The device is listed as Android Phone under Universal Serial Bus device in the Device Manager if I use it in the twrp recovery mode.
If I use adb devices it is listed as offline.
If I go into fastboot mode it is listed as My HTC under Android USB Devices in the Device Manager.
If I use adb devices the phone isn't even recoginzed.
And if I try to install an other driver while it is connected as Android Phone, Windows says that the best drivers are already installed.
Please help me I can't use my phone at all now ...
okey luckily this phone has an sd card slot so I used that for the rom. But has the offline device something to do that you have to activate usb debugging in the devoptions? But what to do if there is no rom installed expect the twrp?
