[Q] Can't boot in any OS anymore (Nexus 7)

Hi guys,
I am new to this Forum and I am German so please understand that my english is not the best.
A few days ago I flashed my Nexus 7 (2012) with the newest Ubuntu Touch Version after having android before. After succesfully flashing the device with the OS it booted with no problem but UbuntuTouch didn't quite come to my expectations, so I decided to switch back to Android. I tried that by simply following the steps that are suggested on the Ubuntu webpage but that did not work out. I tried to just load the Android package to tablet in some other way but now I have the problem, that UbuntuTouch is still installed but when I try to boot it, it gets stucked in a bootloop.
I already tried to "wipe data/factory reset" in the recovery mode but it isn't working. At least bootloader and recovery mode are working fine.
I hope there is some way you can help me solve my problem, if there is anything unclear feel free to ask.
Daniel

I'd suggest asking in the Nexus 7 forum. They know what to do. We probably don't as it's different for every device and the chance that someone comes around who has a Nexus 7 as well is much higher in the Nexus 7 forum. (You know why. ^^)
Please add whether you own the 2012 or 2013 model. Then report your own post by clicking on the orange triangle on the right side of your post and in the text field describe that you want your thread to be moved (ask politely ). Then it'll be in the N7 forum and the people over there will be able to help you. Good luck.

Please help stuck on teamwin screen, can't enter into Recovery

I just got my brand new Aluminum Nexus 6P last night, I wanted to test out the new Developer Preview #4 right away, so enrolled in the program and got the OTA update which I took, and rebooted running Android N, looks pretty neat, and nice tweaks, and some new features. But I always like to run Rooted and install custom ROM's, but Root is #1 for me.
Ok so I need a little help, I am following the excellent video by Rootjunky ( thank you ), and got through the unlocked bootloader part easily, and now installed TWRP Recovery easily too, but upon first time booting into TWRP, it's just sitting at the Blue and Gray teamwin screen, and not doing anything else, it's not actually entering into the Recovery, to see the list of options, etc...
I powered the device down, and started up again in Fastboot mode, then chose Recovery, and does the same again, just sits at the blue gray colored teamwin screen, and does nothing.
What happened ?
UPDATE:
I powered the device down / off. Then started up again, it went and booted up, to the fresh clean Android N DP 4. But I am not rooted at all yet, due not being able to fully enter Recovery and flash the SuperSU zip yet.

The issue is because of encryption... you would need to run fastboot format userdata... and then flash twrp... you would then be able to use it... p.s use the latest twrp version
SENT... isn't that enough

Can you spell that out a little bit for me please ?
So right now I am on the Android N beta 4, I have an unlocked bootloader, and TWRP not booting up for me, so do I need to restart the whole rooting and Recovery method all over again ? I do have a modified boot.img from another thread here dated 06-15, but at what point am I supposed to run the command for format data ? And what is the exact correct sentence and spelling of that command I should enter ?

Wow thanks, but never heard of this thing before. Is it like a all-in-one root kit, that does it all for you ? I have normally followed the YouTube videos on how to do it the long way with command prompt and pushing files to the phone, etc...
Silly question, but with this toolkit, is this something I download and install on the phone itself, or run through my PC ?

Could you stop posting the same question in multiple threads? It's inconsiderate of people's time.

Holy crap, that Nexus Root Toolkit, is like something from Star Trek future. Did Commander Data write this amazing program ? UNBELIEVABLY FANTASTIC PROGRAM.
I was just on the stock phone, not rooted or TWRP or anything, I then install this nexus Toolkit, run the program, and it totally rooted and installed custom TWRP Recovery on my phone, while still being on the Android N 4 preview. I am blown away at how it did all of this, in like 5 minutes.
Couple questions please;
- Android N doesn't have Xposed, so that kind of sucks, but totally expected with this being a beta preview obviously.
- Seems like some root programs not even working, like my classic AdAway, is that due to this being N ?
- How hard is it to revert back to a MM ROM ? Let's say I want to install Pure Nexus ROM, which is already on my SD Card, can I just boot into TWRP Recovery, wipe system, and flash Pure Nexus + GAPPS and reboot ? Or do I need to do something special first to downgrade to MM coming from N now ?

Help reviving a Nexus 7 2013 Flo 32G

I need help reviving a Nexus 7 2013 Flo 32G.
This tablet has sat forgotten and dead for a couple of years. I am trying to bring it back to life. It has been several years since I have done any rooting and flashing on Android, so I am looking for a little guidance. I honestly do not recall what has left the device in its current state. But, basically it has no OS installed. The boot-loader version is FLO-04.04. I can get into recovery. The installed recovery is TWRP v2.8.6.0. I do not possess any Windows machines. I have Android Debug Bridge version 1.0.39 installed on Ubuntu 16.04.3 LTS. MTP is enabled.
But that is it. I am not able to locate the device through ADB using ‘adb devices’. As I say it has been several years since I have rooted around Android or used ADB. I did not use Linux the last time I was doing things like this. So, I am stuck as to how to proceed. I was hoping it was going to be a pretty straightforward process of picking a ROM and GAPS and flashing.
Of course not even being able to ABD into the device leads me to believe that, while not in over my head, I made need some help going forward.
Anyone care to volunteer some first steps?
TIA

Wrong forum dude. This forum is for the 2012 Nexus 7, not the 2013 Nexus 7.

It's fine. People make mistakes sometimes.
Also it looks like something majorly screwed up your Nexus 7. Hope you find a solution to fix it up sooner or later.

Beginner's questions - Which ROM how to flush

Hi,
I've been reading for some hours and did not want to bother you with one more beginner's question but I prefer to ask before rather than pulling my hair off and discovering that I did something wrong. Here are my questions.
I have a Nexus 7 2012 Wifi with android v5.1.1 running on it, extremely slow.
1)To flush a new ROM I saw one movie on youtube that was using the android default bootloader, but here on the forum I read (and later learned what it means) about TWRP. Do I need to first install TWRP on my Nexus 7? can you please help me with a link to a tutorial or even better to a youtube movie on how to install it.
2) I remember a long time ago I flushed the v5 ROM by using an OTG USB Cable, I can't use an normal cable right?
3) Which ROM to choose. I'm not that picky, I guess any would be better than the current one. I read that v7 is pretty good, but there are too many ROMs and I got lost in the acronyms. I need a ROM that will run as fast as possible (at least decently). I do not need any google aps, but I read somewhere that sometimes if you choose a ROM without the gapps (I guess this is the acronym used right) then you do not get even the Google Play. I need Google play to install Chrome and a few applications for my son. (to learn a second language: Duolingo)
More than I do not need. It would be good if the battery would last longer, but it's not a problem if I need to charge it every now and then.
I learned that the ROM that I need is called grouper (wifi only).
4) OTA means over the air. Now I guess that all the rooms for android v7 are unofficial ROMs (meaning not provided by google, sorry if I got it wrong). In this case, does the OTA refers to the security patches provided by Google to patch their OS? or does it refer to the installation of a new ROM without the USB cable, directly from the internal memory
5) I do not care about the internal data, I can delete it all, but I did a factory reset of a Samsung Galaxy A10 (a more recent tablet) and I regretted it dearly, because I had forgotten the username and password that I created when I first used the device, and then I had to take it to an official Samsung repair shop to have it fixed, as it couldn't be used without the original account (username and password). I guess this is not the case for older versions. I can of course check my current Google account that I created while using this tablet for the first time. I checked the Users on the tablet, and I can't really find a Google account, but just a local account. In any case, could anyone of you confirm that if I clean all the data it shouldn't be a problem to install a new ROM afterwards.
Many thanks for your time and efforts in answering the above questions, but also to develop new cool great amazing ROMs that bring old devices back to life.

I think the easiest way to go is using Nexus Root Toolkit and Pure Nexus MM rom. Using NRT is pretty easy as long as driver works. It'll unlock bootloader and install TWRP. After installing rom install Parrot Mod and tablet will be reasonably quick way faster than stock lollipop. Thats what I have and it's still usable.

Hi,
I guess I should be doing something similar with this tutorial (ok the NRT version is newer now).
https://www.youtube.com/watch?v=tdFQtmgHC5M
And then flush the custom ROM that you were talking about the Pure Nexus MM Rom, which is not in the above video.
Do I need an OTG USB cable for that? I need to be careful and test first as the USB port connection was phisicaly tricky (I need to ensure the connection and then do not touch the USB cable anymore so that it does not disconnect). I think if I'm very careful it should be working eventually.
Many thanks

Any USB cable that allows computer to recognize Nexus 7 as a device is ok. Before doing anything make sure that full driver test is successful. Next is OEM unlock which will wipe the device, then TWRP flash and root. Then flash stock from NRT and boot.
Next download PN MM rom, copy to some directory on Nexus 7, boot into TWRP, install, boot. Repeat same with Parrot Mod (flash from TWRP). After that tablet will be usable. ROM build that I have is MTC19Z

Hey guys listen up, your gonna love this! I have a grouper too and i have it using 7.1.2 tried your methods and ended up here, its incredible if you can do these things :
1) Change your data and cache to f2fs which wipes your internal storage.
2) Install crdroid ROM from this week with june kernel.
https://forum.xda-developers.com/nexus-7/development/rom-crdroidv3-8-3-nexus-7-2012-t3710834
3) DO NOT install GAPPs (for ultimate otherwise pico I guess but this beast is old and tired we are trying for ultimate efficiency.)
Ohh and use NRT 2.1.9 to install your select couple of apk's thats it for performance.
4) Despite all warnings try ParrotMod it works for me.
Literally many times faster than PureNexus..

Fresh op6t tmobile, best rom etc for pentesting platform

i have a op6t bootloader unlocked still on tmobile 10.3.3 oos. i want to flash the nethunter/andrax kernel on it so i can check em both out. i am wondering if i should bother trying to flash the international rom on it, or what might be the best rom to use as a base for a pentesting platform.
it is my first oneplus device, but i messed around with nethunter on the galaxy series and kali on maemo before it. ive just gotten the unlock token and flashed it, i tried to msm it to the international rom prior, but kept getting a 'packed image not found' type error. i guess it doesnt matter now, i can just use twrp. but any advice, or direction on what i should flash or install in what order would be Greatly appreciated, im just trying to read up on all of it as much as i can right now.

Reading is good! You'll really need that as you're about to venture on a potential world of pain. I have the international version so it's been smooth sailing for me but I've read a lot about these TMO devices and either it'll work for you if you follow the right guides or it'll go south really fast. And when it does, there's an endless road back to square one. It can be an excellent learning experience and there will usually be a way out but it will require a lot of patience. If you don't have that, you might as well stay with stock. You know yourself best [emoji6]

super good to know, as it sounds like if i can get the msm flash to work, it will be just like an international one. or maybe i can twrp flash it to a newish international oos that will work well with nethunter. But i guess my first order of business should be twrp flash and pull a full backup just in case. i am indeed looking for an odyssey, ive been bricking arm devices since the nokia n800 days so im sure i can figure things out.
im thinking:
twrp
magisk
backup
flash newest internation oos (msm or twrp?)
flash nethunter/andrax kernel
install non chroot nethunter
install andrax
...
profit?
i dunno why but im unreasonably excited to get a pentesting phone running with a kernel that supports native monitor mode and packet injection

I got it all to work, with plenty of haphazard dirty flashing, and only like 3 softbricks where I had to go back to 9x with msm. So I'm on 10.3.7 with twrp, magisk, seems like I disabled encryption, cause I ran into that issue before, and I have no lockscreen code now. I doubt I could reproduce it all, but the nethunter/andrax kernel seemed to have stuck, after I got nethunter chroot installed, I verified monitor mode worked. Got andrax all installed too, everything seems to be functioning properly. Sooo many tools to play with now. It's weird, every time I did things properly, I'd end up bricking it, then I would try some convoluted dirty flash and it would work out just how I wanted it.

Hey im going through some things with the install so i flashed a international rom after the last fix i did with a .bat file from another post which its running fine so far. so could you explain some details with how you went about it at least the decryption part this has me lost as in...
1= TWRP format data
2=flash all the things i need to flash
3= flash DM verity disable force encryption last
all within the twrp.img first boot? or is it all done after twrp is installed
first of all im fresh to all flashing roms and i have been reading like crazy haha just trying to clearify the missing info or lack of maybe.

Dude could you please help me I can't get nethunter running for the life of me, so it sounds you flashed the kernel then flashed nethunter oos10 for the op6 using twrp but it worked for the op6t? I'm pretty new to phones had nethunter on a oneplus one but that was a cakewalk, I got a T-Mobile op6t running international

Hate to bump an old post but did anyone manage to figure out the flash order on this?
And if so care ta share I'll be forever in your debt
