Unable to mount partitions after flashing TWRP on Nexus 7 (2013, WiFi, flo)

I just bought this device a week and I haven't even rooted I wanted to install Cyanogenmode and follow through the instructions and flashed TWRP through fastboot commands from Windows7 using Minimal ADB and Fastboot [8-28-15].
I got the TWRP recovery but I am not sure what have I done wrong, when I am in the TWRP recovery, it does not show any partitions so I am unable to install any ROM on it.
I have also tried to use this thread: http://forum.xda-developers.com/nexus-7-2013/nexus-7-2013-qa/mount-recovery-t3064562 when I flash the given recovery from fastboot commands from this thread, the recovery get stuck with bootloop. So then I restored it back to the original TWRP 2.8.7.0.
So at this point now I can only access bootloader and the recovery which does not show partitions.
At this point Is it possible for me to go back to the stock ROM somehow? Please advice. Otherwise I might be able to return it because I have only bought it few days ago.
SOLVED: To get TWRP to work, I flashed the original stock ROM from here https://developers.google.com/androi...s/images?hl=en using adb. I then flashed this TWRP multirom https://s.basketbuild.com/filedl/dev...o_20150630.img
This allowed TWRP to work.
Thanks to Batfink33 and lynnux

You can follow this guide to flash the newest factory image: http://androidforums.com/threads/guide-how-to-flash-a-nexus-factory-image-manually.706533/. You should just download the latest factory image from: https://developers.google.com/android/nexus/images?hl=en the one in the guide is outdated.

Join the club, I did the same thing you did with the same results(even flashing the multirom twrp after flashing the regular one, and getting the recovery bootloop). I happened to find the same instructions theminikiller posted above after pulling my hair out trying to figure out what went wrong.
This post http://forum.xda-developers.com/showpost.php?p=62275723&postcount=558 explains what's going on. If you do the above and then flash the multirom twrp it should work fine, it did for me. I also reformatted system in adb after erasing everything, not sure if that was necessary or not.

Did the multirom TWRP work for you? I get a bootloop in TWRP when I flash that multirom TWRP posted.

It worked for me, but only after erasing everything via adb and reflashing all the stock images. I got the bootloop when I flashed the regular twrp first, then the multirom twrp. Also, I'm using the most recent multirom twrp from June (I believe).

Is it required to enable Developer options at some point of flashing it successfully? I am in China and here the google is blocked i bought this tablet and I can not get through the first screen that ask me to connect the wifi (no option to skip it unless i connect to wifi) then after loading it gets error message that it is failed to connect to internet. So just understand that I can not goto the device options right now. So is it possible to flash cynagonmode rom without enabling developer option. Please advice

No, it's not required. Just turn off your device. Then to boot into the bootloader hold volume down + power button until it's done booting. From there you can follow other guides to unlock the bootloader and installing custom recovery and Rom's.

I have tried to do it. But the device is not being recognized with the ADB tools on my PC. Any ideas? Could it be because of the USB debugging option?

When you are in the bootloader it doesn't matter if you have USB debugging enabled or not. It could be a problem with your driver's.

Recovery Screen Blank!

Hi,
I have a unlocked bootloader and a rooted phone(OnePlus3). I was clean flashing to a newer cm14 nightly on my oneplus 3 when I discovered a while later that my phone wouldn't boot into recovery mode. After flashing TWRP recovery, I booted onto my phone and selected recovery in the advanced reboot menu however it started to flash into fastboot whether i tried to fboot into recovery or into fastboot. So i, maybe mistakenly(i'm not sure), flashed stock recovery in command prompt and now there seems to be ,arginal improvement as I think a recovery mode may exist however the screen is blank so i have to power off by holding the button for a couple of seconds before anything appears on the screen and it does but only for fastboot and booting onto the system. Please help, I want to revert to Stock Oxygen OS with TWRP recovery but am unable to do do. I find it imperative for this to get resolved as my phone doesn't have gapps and doesn't offer much use beyond browsing. Any help would be massively appreciated.
Thanks!
P.S I apologise, in advance, if i have broken any forum rules; please tell me if I have so i will know not to do so again
P.P.S I may not understand some procedures or terms mentioned so please explain fully what to do as if I'm a complete noobie

I'm not quite understanding your situation. Can you get into fastboot or adb mode or no?
You can also skip right to http://forum.xda-developers.com/oneplus-3/how-to/guide-mega-unbrick-guide-hard-bricked-t3405700 and follow Method 2.
On a side note, what version of TWRP were you on? You need to be on the modified TWRP, not the official TWRP, for official 14.1 nightlies.

Yes i can get into fastboot mode on my phone but the problem present is recovery mode has a blank screen . And command prompt recognises my phone when I type fastboot devices.

I'm guessing you're running official TWRP? Official 14.1 nightlies needs the modified TWRP http://forum.xda-developers.com/devdb/project/dl/?id=21065. If you have fastboot access, you should be able to flash this version.

After flashing CM14.1 Nightly, I can't boot into recovery.

Hello guys,
As stated in the title, I can not boot into recovery since I flashed CM 14.1. I already tried reflashing TWRP, booting TWRP via fastboot, using another, more recent TWRP image.
This is rather urgent, since, although I can boot CM 14.1 without any problem, I forgot to do a Titanium Backup of two apps, so I have to restore a nandroid backup to get those back, which is kind of hard, without access to TWRP. Using TWRP Explorer is out of question, since that, as far as I know, does not work with encrypted backups.
Flashing via Flashify does not work either.
I just tried with the most recent CM Recovery, that does work, but that does not really help, since that won't restore TWRP Backups..
Greetings

Just flash twrp again!?

Flash the twrp in the following link https://www.androidfilehost.com/? using flashify from play store .This helped me

That did not work, at least not with the official TWRP. Flashing this TWRP gave me TWRP back, but now restoring the Backup somehow did not work as expected, the old CM 14.1 unofficial build that is in that backup won't boot.
I'll try only restoring the data part onto the official build, is there anything else you can recommend? Another firmware? Something?
Oh and by the way, thank you, for helping here and for you CM 14.1 builds, somehow I couldn't build CM 14.1 and 14, so having your builds was really helpful.

What version of OOS was you on prior to flashing CM14.1?

Directly upon receiving my OP3 I flashed CM13, that was in August, so 3.2.4 I guess, and I flashed the firmware of 3.2.6 before flashing Takers and your CM14 and later 14.1 builds.
TWRP behaves funny, the progress of restoring Data is already at 138%, 6800MB of 4899MB, the calculation is not taking compression into account I guess?
LOOOL, I have booted into the official CM14.1 with the old data, no fc or anything, but my pattern does not work anymore. same pattern as before, won't be accepted.

Never seen that issue before what happens if you reboot into the bootloader and then connect the phone to your pc and type fastboot boot <name of recovery> does it boot up?
Of course replace the < > with the name of the img file.

Yes, TWRP works now, but the backed up unofficial CM 14.1 does not boot.
But, only this TWRP works, booting the official TWRP does not work.
I could probably just use the TWRP file manager to extract the few files from the data partition that I need, but this is a workaround and not a fix, and that is not desired in most cases. Fixing it is hard without someone that still has a broken system.

Do you know how one would debug something like that? I have nothing but the splash screen in the beginning and then a black screen
I will just flash CM 14.1 and manually extract my OTP tokens from the data backup, so I don't really need to debug that, but it would probably help determine the cause and properly fix it for the future.

Ask for the link

Sorry to hear that. You have to use Qualcomm Drivers to reset your cellphone

Same issue here. Whenever I try to boot into recovery it just goes straight back to the bootloader/fastboot.
**** me, what do I do?

I try "fastboot format userdata" but after i have the same problem with TWRP-3.0.2-1.28

Can you get into fastboot?
If so, you can sideload a working TWRP via there.

Can't boot into recovery

Hi to everyone!
I recently bought a second-hand Redmi Note 8 Pro, did a factory reset and started working on it! I found some problems, such as:
1) Google Pay doesn't work; when I try to add a credit card it says something about my phone being rooted etc.
2) I can't connect to public WiFi's through their webpage (without a normal password directly), as it won't load the respective page.
3) I can't update MIUI version as it says "Couldn't verify update".
4) I can't login into Xiaomi Services (Cloud).
I did some searching and came to the conclusion that if I root my phone maybe I can find workarounds for the above. So I tried getting into rooting.
Every tutorial started with unlocking the bootloader, but in dev options OEM Unlock is greyed out with the switch off and it says "Bootloader already unlocked". So, first step clear (right...?).
The next step is to reboot into fastboot mode and through some hacker-like commands in cmd to flash a recovery image, which I did successfully (according to screen indications and such...).
BUT!
Although everything seems perfect, my phone won't reboot into recovery, neither Mi's nor TWRP. I've tried every way (from cmd and with volume buttons etc) and many older versions, it just won't load!
It just reboots into Redmi screen (it has an unlocked locker at the top), then a little black, then again this screen, then MIUI screen, then PIN screen etc.
What should I do? Thank you in advance!

Question Bootloop after battery died

Yesterday it happend suddenly: Battery 5% left, just a quick newsarticle before bed and it left me.
At first it didn't even take any charge. Booted in recovery and it's at 40% now.
But booting doesn't work.
OP Logo, bootanimation for around 20 seconds, repeat...
What I tried:
Power off, reboot
changed active slot
Flash the boot image what was last downloaded by me a while ago (semed to be Boot 12.C44_BA, not sure)
Flash the magisk image
Flashed a C47 image
no difference at all, same boot pattern.
A little sidenote:
I have magisk on my op9p, worked fine. a recent ota update failed repeatedly installing in defaulkt way. at boot i had to switch active slot in fastboot a few times. then it booted to current firmware.
I am wondering why i get the same issue independent from the boot.img.
Why did the low battery started this problem at all? How can i be sure to have the right boot.img flashed.
And most important: how can i boot into andoird again?
let me know if you need more information.
Thanks in advance!
edit:
is it possible to install twrp and backup/restore later the important data?

thanks for the hint! I read about this tool. But this means a full wipe of system and user data, right? any chance to avoid this and rescue images before setting up new?

I see a few possibilities to get closer:
i can boot twrp via fastboot. wiping data seemed to not help.
mounting userdata doesn't work because it needs a pin code which is not my system code.
maybe i have the wrong boot.img? can i find out which firmware version is installed via twrp and flash the right image afterwards?

Click on "advanced options" in the tool and that'll bring you to "adb sideload". I hope that works for you!

This sounds promising. I will try that later. To be sure: This will keep personal data like an usual ota update?
Edit: I'm still stuck. Heres what i do: Boot twrp (not install) from fastboot. in twrp start adb sideload. open the toolaio, generic device, advanced options, select firmware.zip and click flash under sideload. Than it prompts "phone is not in adb or fastboot mode". In the main window it show the device id and "adb sideload".
what am i missing?
