Two Nexus 7 stuck in bootloop - Nexus 7 Q&A, Help & Troubleshooting

I got an email from my aunt today and both my niece and nephew's Nexus 7 tablets wont boot up anymore. I think they took an update that bricked them both. They are codenamed grouper which I think is this 2012 version right? Anyway, Ill attach a picture of what they look like and maybe it is a common enough issue that the people here on this subforum can help me out on what to do I have used a Nexus before so I know how to do fastboot commands and ADB stuff and can push a ROM and kernel that way, but my aunt tells me that neither device will come up on the PC when plugged in even after downloading the newest drivers. Ill see for myself tomorrow, because I doubt she downloaded fastboot and ADB drivers to try. But figured I would post here about it and hope I can get some answers to start me off on what to do when I pick up the tablets. Both tablets are fully stock so no unlocking or rotting done to them, they were purchased last year.

I got them working. It had some issues because it kept saying invalid argument when I tried to flash stuff, but I eventually got it and now they are working again and both running unlocked with CM11 M9

[Q] Nexus 7 stuck on Nexus logo!

Hi guys,
I know there are threads on this but I would like to start a fresh one just so I don't get confused.
Basically I was running Paranoid Android no problem and then I downloaded the MODACO Rom Jr9 and flashed that, it was working fine with no problems then I thought to flash Motley Kernel r25.
It did that fine then I clicked reboot and it is now stuck on the Nexus logo just flashing. I panicked so opened up Wugs toolkit 1.5.5 and "Flash stock and unroot".
It downloaded the files from Google and the CMD window popped up and I got this,
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
It then flashed to the next screen saying that it is waiting for the device to boot up which it didn't. It just stayed in bootloader.
I did it manually and it is still stuck on the Nexus logo. I can boot into TWRP and I have tried clearing the cache etc but nothing is working.
Please help me if you can.
Sorry again for starting a new thread but I think it would be best for me to understand if I am not reading through other posts right now!
I have just tried this guide...

I have just tried this guide again and it seems to be working. Will update when it is done.
Thanks guys anyway.

Keyboard Glitch/Broken after Rooting/Flashfyre

Hi guys,
I have a fresh S7 SM-G930V(Android 6.0.1). Which i logged in via google and it downloaded all my previous apps on my old phone(i assume it automatically does)
I was following https://forum.xda-developers.com/ve...-to-notes-root-install-xposed-unroot-t3411039.
And now my keyboard is now starting to look weird
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I completed all the steps and rooted to the following image "Samsung_G930x_QC_Rooted_BOOT.TAR (any Samsung Galaxy S7) (MD5 hash 948A01ECCF280828DFD13AC366F6FE85)"
and used Odin3_v3.12_PrinceComsy.zip as opposed to the other odin.
Any ideas besides using another keyboard app?
EDIT: Just flashed back to G930VVRU4API3, which i thought was my stock rom but has a purpleish first time start up which i thought should be blueish?
Going to try and re-flash a root after work again.
UPDATE2: I Follow the rooting/xposed steps again and now i got my normal keyboard back. The difference is that the verizon startup is white/red while when i first ever used the phone it was a blueish/purple verizon start up. But i feel that it was definitely 6.0.1 with PI3.
Accessing the phone via cable seems extremely slow but thats for another thread...
I am now rooted with a working keyboard, now time to work on the other issues....

You're not the only one, same for me and some other Note FE SM-N935F/DS users...
Seems like that only the Korean variant doesn't have this problem as they can just flash the standard TWRP without problems.
Anyone able to boot back to main screen without flashing stock ROM?
So there's no working root method yet for N935F/DS. Seems we have to wait for a year? Hope not. I like their phones but I hate Samsung!

Are your next 10 posts going to be the exact same as this one & the three preceding it?
Try reading the existing threads before posting identical questions/threads, it's not as if there's a lot to catch up on.......
