First, I searched and read all relevant threads concerning this issue. The five threads that showed up in the search did not help me solve my issue.
So on to my problem. I can no longer flash any rom onto my device. I attempted to flash the first official CM10 nightly (which I recently found out was not flashing properly for others) and had no success. I simply got a black screen and nothing more. I eventually got back into TWRP (v2.2.1.4) to try and Nandroid restore, but I noticed that /data was not formatting and the restore failed. Every time I would slide the bar across to confirm the restore TWRP would reboot itself. I then flashed CWM (v6.0.1.0) and the same problems were there. After that I flashed an earlier version of TWRP and successfully restored the backup. I'm not 100% sure how it was successful. So I decided to try flashing another ROM and no go. Same problems. Anyone have any ideas? When I was using CWM I got the error message below.
Code:
E: unable to locate volume information
E: unable to open ums lunfile '/sys/devices/platform/usb_mass_storage/lun0/file'
E: unable to format data
I'm running Bugless Beast with Motley #219
I'm having similar, if not identical problems. After flashing TWRP 2.2.1.4, I tried flashing a rom and gapps; the tablet would boot endlessly into recovery. Nothing I did would do anything, so I flashed the stock image to start over. This time, I used CWM 6.0.1.0 touch to make sure that it wasn't the recovery that was causing the problem. However, now after flashing the rom and gapps, instead of booting into recovery, I got stuck at a black screen and had to hold the power button in order to get back to the bootloader.
Now, like you, it seems I can't flash any roms anymore. It's frustrating to say the least.

There is a bug with the Nexus 7 where you cannot access the recovery through the bootloader. To fix this, boot up into the bootloader on your nexus 7 and, without doing anything, plug it into the computer you used for rooting it and then select the option Restart bootloader and press the power button. Once it gets you back into the bootloader again select Recovery mode and press the power button. It will now get you into the recovery and once you're in recovery you can unplug your tablet from the computer. Note that this fix is not permanent and you will have to do this every time you wish to access your recovery via the bootloader (and this problem is not relevant to the OP's problem).

Thank You Very Much!!!
I am having much the same problem as the OP. I finally rooted my Nexus 7 using WugFresh's Nexus Root Toolkit. It seemed all went well. I chose to use TWRP in a first attempt to install a ROM (I was on rooted stock), and following the instructions for installing my chosen ROM I went into it to wipe cache, Dalvic Cache and data. Both cache and dalvic cache wiped without issue, but when I attempted to wipe /data TWRP simply reported that it failed. With that failing, I did not attempt to install a rom. I was still able to boot out of recovery, but even with repeated attempts wiping data always failed. Is any one aware of any solution or have any suggestions. Thank you!
My phone originally was using omega rom and philz recovery. I accidentally pressed the "remove recovery flash" while in philz recovery when I was trying to reboot the phone. My phone couldn't boot to os nor recovery, but download mode still works. So I tried to flash custom recovery again but it does not work. Tried flashing stock rom and kernel but recovery does not work. However, the phone is now able to boot to os but the screen color gone wrong. The whole screen is purple-ish when in os.
How can I get back recovery and also solve the purple problem?
Maybe try using a different recovery, at least to get back to stable? I've used TWRP and OUDHS via Odin, and both work well.

Thanks alot! Finally able to enter recovery. Spent quite a long time trying to flash different roms etc.
Now trying to solve the purple problem....
Edit: Everything working fine now.
hi guys,
my find 5 was having some reboot issues (it was rebooting a few times per day) and that was a bit anoying. I was using an old original FW so i decided to update to a newer one. Heard good stuff about the Omni so i went for that, so i was using TWRP 2.4.1.0 (i think... i'm sure it was 2.4.x) and on the omni page they said we have to use TWRP 2.6 so i went for an update.
here, i think, i've created my problem. I used the new flashify app to install the TWRP but instead of choose recovery img i choosed to flash the boot and i guess i'd flashed the TWRP on the boot.
well anyaway, now i'd installed the TWRP 2.6.3.1 i manage to start the phone in fastboot and recovery all good here, i install every rom nice and easy over TWRP but the phone simply doesn't start, it gets stuck on Touchscreen Firmware Update please wait.... this happens ALWAYS with what version of TWRP or even if i install CWM...
my guess is that i'd messed up some partition or so i don't really know what but i'd tried to format every partition that TWRP let me and still getting the freackin Touchscreen Frim updt screen... so need some Pro help to help me undo the mistake i'd done...
thanks for everything
On the official Oppo forum's there's a guide on how to install the latest Omnirom. Under known issues it says:
5)After installing the TWRP recovery the Screen Touch firmware update goes on for more than 5-7 minutes, do a hard reboot and you would be fine,

I haven't tried it myself since I didn't get the problem when flashing Omni and Asylum, but it seems to be worth a shot.
In case you are looking for the topic, search for "How to Install OmniRom 4.4".
I've had my note 4 for a little while now and I've been trying a lot of roms. Yesterday I tried flashing the flyme os 6 beta which I couldn't get to boot up. After that I flashed back the rom I was coming from and I noticed that twrp was unable to boot to recovery or system and went straight to stock recovery mode. When I manually started the rom up and tried to boot to twrp the screen went black for about a minute before booting into recovery. I've tried flashing back the factory images, reflashing twrp, different kernels, different BL and CP versions but nothing seems to work, I keep having this weird issue.
PS: I also can't turn it on when it's powered off. I have to remove the battery first before I can.
Has anyone else had this / knows how to get rid of this issue?
Better option is to try flashing stock firmware using odin download mode.
Hey, I'm new here when it comes to writing forum posts, so bare with me.
I've had this tablet for a few years now and I had flashed it with one of Magendanz roms (Nexus Stock) and I wanted to change to the LineageOS rom he had. I downloaded the .zip file and copied it to my sdcard and tried to get into TWRP to flash it. I did restart to recovery in the OS and once it restarted, it's been doing a boot loop ever since. I have tried using Odin to flash the rom that way, but for some reason it'll keep doing a boot loop after it's done flashing and restart. I can try going back to the stock firmware if it's a final option to get this tablet working again, but I would love to see if I can get LineageOS to work.

I had a similar issue once. It turned out that after flashing, not all the partitions mounted properly.
Are you still using TWRP? Boot to recovery, and go into "Mount". Make sure the system and other partitions are actually ticked. That solved the problem for me, and I was able to successfully boot to the system.
Hopefully your issue is that simple!
I managed to brick my Tab A 10.1 (2019) last year by dirty flashing ROMs I shouldn't have. I properly munted it, I couldn't even get into recovery. But I could still get into download mode with a USB cable plugged in to my laptop (it needed to be plugged in for download mode to come up). I flashed the stock ROM, which made it bootable again, which then allowed me to re-flash TWRP and then Magendanz' LOS18.1 ROM.
If you completely break your tablet, reflashing the latest stock ROM for your region is a great way to get back to a familiar starting point. You can then follow people's guides online to get where you want to be.
