Help with my N9 - Nexus 9 Q&A, Help & Troubleshooting

I was running the Pure Nexus ROM but took the decision to try a new one, that's when the trouble started.
Before semi bricking the N9, i updated the version of TWRP on it to 3.2.1-0 and installed supersu as it wasn't rooted prior to messing it up.
IO think the trouble started when TWRP was asking for a password, and it didn't match the PIN i had setup. Anyway, i d/loaded slimrom 7.1.2 and gapps to root of SD card, did a factory reset and wiped, system, dalvik and cache. When i went to flash the new ROM, i couldn't see the zip file in the root folder.
If i look at the root folder in recovery, i see one of the images below and the other when rebooting the tablet.
When i try to connect the N9 to my windows 10 PC it is not being detected, i don't know why do to about this to try and go down the adb route.
I have installed Android Studio to try and move things on, but i don't know what to do next, or even if anything can be done.
I am almost sure i had the OEM unlocked before flashing the rom.
Can someone suggest what i should try next? I won't be able to check back in for a day or two due to work, but i definitely will when i get the chance.
TIA

Did you format data? To remove encryption. Format, not wipe.

Gave it a go, no luck unfortunately. The sdcard is as the attached image.
I have ordered an OTG cable, hopefully i will be able to flash a rom that way on TWRP.
Edit: i was able to borrow an OTG cable. I formatted it FAT32 on windows PC and copied across the rom zip file. I rebooted into recovery on N9, and tried to mount the usb drive, but it is not appearing on the list of devices. When i pligged the same OTG cable and attached usb drive into my phone, it picked them up, so i think the otg cable i am using is good.

If you formatted data, there won't be anything on sdcard. You'll have to either push it with adb, or as you said otg.
Or download the factory image and fastboot flash to start over. Or sideload the full OTA zip (they have full images of ota zips now).

Got it sorted in the end. Embarrassingly the reason the tablet wasn't detected by my Windows PC is because the cable was a little lose.

Go into TWRP and adb push a rom.
There is also USB storage under mounts.

can someone tell me how i can push a file in adb
You could always go back to stock ATT firmware. Download the LGNPST and the firmware and then put your phone into download mode and flash it. This will overwrite your recovery with stock stuff but at least you will have something running so you can start over.

I was looking into that but adb seems a lot easier. just push a rom onto the phone and flash it right there. Ill see how that works out

If you have an OTG cable you can also load a ROM onto a USB flash drive and connect it to your phone via the OTG cable. TWRP will need to be set to "External SD" in order to see it. I had to do that with my Nexus 7 when I did something similar.
Edit: Duh, I'm an idiot. It would be far easier to unmount your microSD card with TWRP, take it out of your phone, put it in a SD adapter, then load the ROM to the card from your PC, put it back in your phone, remount it in TWRP and then set it to "External SD" to flash the ROM. Provided you don't have an OTG cable, but do have a SD adapter.

Dude, all you have to do is mount your storage, download which ever Rom u want on your computer and transfer it to your phone. Then do the wipes and flash the rom.
i did that once, thats y i keep copies of my fave roms on my extSD, twrp can read from the extSD and flash from that. i've done nocturnal and slick from flashed from my extSD not internal and it worked just fine, if u prefer tho twrp can copy the file to the internal storage and u can flash that. if u dont have any roms on ur extSD just plug that into the comp and copy a rom to it then restart in recovery and flash away...same idea as baron but using the extSD instead of mounting storage and plugging the phone into the computer

sideload/push help please

I previously had an android revolution hd rom installed, which i love... but due to some tinkering it no longer boots, it's stuck on the htc one loading screen.
However I also deleted that rom off the internal memory, which comes under the directory of "sdcard" even though the htc one doesn't have one.
This means I can't reinstall from the rom zip.
I have an updated version of android revolution, but how do i get it onto my phones internal memory?
After doing some googling , I came up with information about sideload, but because adb doesn't detect my device via clockwork mod recovery I don't think I can proceed.
Adb does however detect the device while it's on the stuck htc one loading screen. I think probably sideload isn't an option from this point?
Do i have to use adp push command?
God i wish htc one had an sd memory card, this wouldn't be a problem.
On a side note i have a device which allows me to insert a usb pen drive via the micro usb slot (which i can easily put a rom onto)
is that a viable way of performing the installation?
Really desperate for any help here, am a a loss why sideload isn't working from clockwork mod recovery.

How to place Custom ROM file on HTC One w/ no Operating System?!

Hi,
This is my first time rooting my HTC One (T-Mobile) and have managed to unlock my bootloader and install TWRP Recovery. Long story short, while attempting to install the latest Android Revolution HD Custom ROM, I seemed to have wiped my whole phone clean and don't even have an operating system anymore.
How can I get the Custom ROM file from my computer to my phone if I don't even have an operating system to boot into? It would be no problem if this phone had an SD card slot, but it doesn't . The only thing I can boot into now is the TWRP Recovery.
I have tried using the MOUNT option in TWRP Recovery, but to no avail. I have also tried to download HTC Sync Manager and the computer still does not recognize my HTC One. All I need is for my computer to recognize my phone and pop up in Windows Explorer so I can copy it into my phone's internal memory and use TWRP Recovery to install the ROM.
P.S. I am using Windows 8.1 64-bit.
PLEASE HELP ME! :'(
I am in the same situation, i have no operating system and can't access the internal storage.
How do I enable usb debugging?
USB OTG
Hi guys,
I just had this same problem. I formatted internal storage and had no OS at all.
I bought a USB OTG wire from Amazon. I put the ROM I wanted to install on a regular USB Drive and connected it using the USB OTG wire.
http://www.amazon.com/StarTech-com-...e=UTF8&qid=1398213984&sr=8-2&keywords=usb+otg
In TWRP I went to the Mount function and unchecked all boxes except USB OTG. Make sure that's checked. Then, go to install and navigate up folders to the top level folder. Scroll down and the bottom folder will be called USB OTG. Look in there for your ROM.
Install and enjoy!
Now if someone could help me figure out why ADB won't connect: http://forum.xda-developers.com/showthread.php?t=2727881

Can't Mount SD & Can't Download with Odin... STUCK

I have a Samsung GT-i9100 and all I wanted to do was install CyanogenMod 12.1 custom ROM and partition the internal SD to something like 4 GB rather than 2 GB. WELL... this has been a complete nightmare.
I already had Slimsaber's custom ROM (Kitkat 4.4.4) with TWRP. I decided to wipe everything to start fresh. Then I went to mount the microsd card to install the new ROM... and... nothing happens. It won't mount. No error, no nothing. Just highlights blue as if it's about to mount, but it never gets the X in the box beside it and mounts. Just continues to be a blank box. I can't access the microSD card at all. The card I have is FAT32 and it works in other Android systems just fine.
Then I try mounting the USB to my computer. Nothing. No sounds like Windows is detecting it. Nothing. I make sure I have all the appropriate drivers installed. Nothing.
So off I go to try Odin. Still no detection on my computer. So I can't use Odin either.
What do I do?!?!
Stupid cord. It was the stupid cord. I switched it and now ADB sideloader, and USB Storage and everything works fine. Ugh. Transferring ROM file to flash right now!!!
Although if someone could shed some light as to why I can't mount the microSD card... that would be great.

It could be many factors. Sometimes changing the recovery will make it work, it could be the sd card has shat itself. Try flashing the latest philz recovery from sdcard0 then reboot into recovery. This has worked for me in the past

U can use a USB OTG or SD with the stock rom or u can push the zip via adb and flash via recovery.

borrow it from someone for abit. sd card is easy to come by. cause if you can't do adb, there's really no other way to flash your rom in then via otg or sd.

omg, are you serious.. you can use an adapter. If they don't have an adapter, just put the sd card into some other phone, and connect that other phone via usb to your pc and transfer the rom

So... I don't even know, if I use ADB right. I use it in this way:
I boot into recovery - Open ADB on Computer - Plug my phone into the computer - Tap in the recovery ADB sideload - Its loading, loading... While its loading I check, if my ADB on my computer finds my phone (adb devices), it don't find it - my phone displays after a few minutes a red error (just one word, error)
So, am I doing right? Please correct me, if I doing sth wrong. Thanks
If you have TWRP then you should be able to connect your phone to PC via usb and transfer data on internal storage via MTP.
Hey,
All u need is a little work, firstly I would recommend you to buy 1 sdcard as it's so cheap and easy to get rather than borrowing it from friend, as u may need it again sooner or later.
Second, after u plug in usb cable to pc, please check whether your pc has installed right adb driver for your device or it wont work for adb sideload command.
Third, ensure you have the right rom for your device, I assume you have it downloaded into your pc. Just open the adb terminal and type adb sideload filename.zip . and it will automatically start installation process.
Dont forget to make a full nandroid backup at least once and save it in Sdcard or cloud storage for emergency case like one you're facing now.
Good luck buddy [emoji1]

Hey, I am not a noob, but I too accidentally deleted my internal memory of samsung SM-N750. I am quite experienced in using odin and flashing kernels etc. But I am stupidly impatient. Today I performed a nandroid backup, then went ahead and wiped off ALL DATA except sd card! It was cuz of lack of awareness and shortage of time. I am preparing for my college exams, suddenly xposed framework caused repeated bootloops, so I decided to perform a proper rom installation, root and xposed right from scratch.
Anyways, I easily installed the lollipop rom via odin, rooted it and everything's peachy.
Is there any way of recovering that nandroid backup zip file, which was on the internal storage? In short, Does twrp perform a full wipe or quick wipe of storage?
I tried using an app "undeleter" but it didn't find any such (around 4gb) zip file in the internal storage. Any other android or windows based apps?
I don't stand to lose too much, just that I would have to install all apps and settings etc which will waste a lot of time.
@arya809
I believe that big files are harder to recover. There's an app called DiskDigger but to recover .zip files you need the pro version which is paid and it can't guarantee that you will recover your file. I do not know any other app that might help you (there are many apps for windows but I can't recommend a particular one since I haven't used any).
If you didn't lost important data I will recommend to install them manually. You can use your PC and install the desired apps directly from http://play.google.com/ (it might be slightly faster to find and install them).
Boot up the recovery, plug it into your computer, your device should show up in the file manager, copy the ROM to the device, and then flash it

There is a device called card reader(some wizard from hogwarts invented it) which will help you to copy data to sd card from your computer
And did you tried mount option in twrp???
In twrp first click mount internal storage the connect it with usb cable it will show storage on your device then copy the rom to it.
Sorry for bad english
