Nexus 7 major issues, may be bricked, guides don't seem to account for my problem

Hi, this forum seems pretty active, which is exciting! Hopefully someone can help me out here. I have searched a bunch and see a lot of similar things to my problem, but I'm running into issues that aren't really described by anything else I am looking at.

Quick background
The device is a 2013 Nexus 7, Wi-Fi version. I never unlocked/rooted the device, so it was basically factory settings. On Thursday everything was working fine. Later that day, it started showing the message "unfortunately the process google.process.gapps has stopped" as soon as I unlocked, even after rebooting. I was not launching any apps. I could navigate for about 1 second every time I hit "OK" on the error before it popped back up, so I tried all the fixes I had found online for the problem (clearing app cache/preferences, disabling/enabling download manager, etc). I decided just to wipe the device and reset from factory defaults. I wasn't confident in the Factory Reset working correctly while the error kept popping up, so I booted into Recovery Mode and just decided to do the Factory Reset from there.

The reset seemed to freeze, but eventually the device rebooted and I got the text "erasing" with the animated robot. This will stay that way for forever, though sometimes it eventually turns into the android icon with the red exclamation mark.

The current problem
Right now, if I boot the device normally, it will show the google logo, then go into "Erasing", which animates. If I hit Power+volume up, it seems to be "erasing /data" but it never gets further than that. If I turn it off, it will turn itself back on and go back to erasing. I have left it on for 14+ hours and it never progresses, other than the times it sometimes stops showing "Erasing" and instead just goes to the red exclamation mark.

I can get to the bootloader menu by holding volume down+power. If I select recovery mode, it shows the Android animating logo (no text) and if I hit Power+Volume Up it shows "Formatting /data..." in the bottom. Eventually this fails and recovery mode will pop up with the following text at the bottom:

Code:

---

Formatting /data...
E:failed to mount /cache (Invalid Argument)
Formatting /cache....
E:failed to mount /cache (Invalid Argument)
E:Can't mount /cache/recovery/log
E:Can't open /cache/recovery/log
E:failed to mount /cache (Invalid Argument)
E:Can't mount /cache/recovery/last_log
E:Can't open /cache/recovery/last_log
etc for last_install, last_kmsg, log, and then repeated all again 1 more time
E:Failed closing /dev/block/platform/msm_sdcc.l/by-name/misc (I/O error)
E:Failed to mount /cache (Invalid argument)

---

If I select "Factory reset/wipe" now, it shows the following:

Code:

---

--Wiping data...
Formatting /data...
then all of the above errors again

---

I tried downloading and installing the Nexus Root Toolkit and running the "Flash Stock + Unroot" iwth the "Soft-bricked/bootloop" option, but all it seems to do is restart the device a bunch of times and then get stuck on "erasing 'userdata'...

Any suggestions on how I might be able to repair my device? It seems completely screwed up, I have no experience with the flashing/bootloading stuff.

Thanks!

No OS installed, don't know what region of firmware to download

So I tried to root my Samsung Galaxy S6 today using TWRP and it got stuck in a boot loop. I went to wipe to cache and accidentally wiped to system. So now there is no OS installed. I know I need to somehow put an OS on the device but I'm in Canada and when I go to samsung's site to download the firmware, there is no Canada option. I bought the phone off of amazon and it came with a European wall charger because it was imported, but how do I know what firmware to download?
Also, when I have found the right firmware, how do I flash it onto the device? I can no longer access TWRP, all I can get is the downloading screen thing. Can I use Odin/how do I use Odin?
Somebody help me I'm panicking because I broke my brand new phone!

HELP ME PLEASE!! Phone doesnt work at all, I'm so frustrated dont know what to do =(

Hello! I'm Nicolas, from Chile. And i own a Xiaomi Mi4 Since March2015.The thing goes like this, since May the screen had a fringe/bar where the touch sensor stopped working, this was NEVER a problem, because it was an area that we never use. But 2 days ago, i pressed the power button to turn on the screen and put my password, but the screen went mad and showed just fringes with lots of colors, then it barely showed the password screen, then colors again and etc, sometimes it worked fine for like 10 seconds, and it crashed again. The phone started working awfully slow, i mean, with like 4 seconds delay for EVERYTHING, i couldnt use it!!. Sometimes it worked just fine then the screen went mad again, with fringes and dots and black or blank screens. I never did hit the phone in the process, not any kick, nothing, the screen just stopped working, all black. The next day i changed the screen (because i thought there was a problem with the screen cause it was previously with an issue, and i thought the ultra laggy system was a problem with the screen or something, that the incredible lag/delay was because the screen). And the thing is when i changed the screen, a brand new one, the exact same thing happened, nothing works, it is alive because i can screencast the phone on my laptop, but it keeps running incredibly slow, it is too slow i cant even open whatsapp without waiting 2 minutes... I cant even put my password smoothly, because it is so laggy and delayed, that if i press the number "1" it shows up on the screen like 4 seconds later... And i mean it shows up << on the laptop screen>> (not to forget the brand new screen doesnt work neither)... So it is a problem with the processor? the ram? the adreno 330? what? Please i need help, i cant afford a new phone =(.

Plus info: Everything seems to be connected alright, i did the replacement myself watching lots of videos, and everything is simple and i think well done, the phone is still alive, but controlling it by the laptop, screen doesnt work, wifi doesnt work (its like there is no adapter anymore...), 3g signal doesnt work, it does not even recognize my phone company it says no service, I controled it by the laptop and now is playing music at full volume...

I didnt know where to post this, sorry if misplaced.

HELP ME PLEASE!! I would be so thankful! =(

huawei p7 don't start anymore ...

Help needed,
My huawei P7 lay on my desk, suddenly it shut down and I can't get it start again.
First I thought the battery is empty, so I put on the charger, but if I press the start button there only came a short hum and nothing happens.
It's also impossible to start into the recovery....
The phone only hums and nothing happens....
I've rooted the phone in October 2014 and also unlock the boot sector......
Went to my dealer and give the phone to the guarantee.... but after some days I get the message that my guarantee is forfeited, because I've installed foreign software...
But that also shows my that they were able to start the phone, because how they should know that there is an alternative recovery installed...
I told them they should send the phone back to me ..... (Don't have it back yet)
Could anyone give me an advice how to start the phone if I get it back and it doesn't start ....
Tanks a lot

Warning: CM11 and 12 don't work with the latest versions of TWRP and Philz touch

The short story: I tried to update from CM11 to CM12 snapshot on 9/1/2015, but every CM based ROM would get stuck at CM boot logo, and this is true with the latest TWRP and latest Philz, along with the snapshot CM recovery provided at the official download page. After downgrading to TWRP 2.6.3.0 at the suggestion of http://forum.xda-developers.com/note...2972922/page32, I got it working.

The long story:

I tried to update to CM12 over the air from CM11. That didn't work, as my philz touch recovery just boot directly back to CM11. It's too quick for me to see the install logs, but there was some error message like "can't install" etc.
So I thought maybe I need a different recovery, since the update notice does say "compatible recovery required" and I saw there is such a recovery in the CM download site.
I flashed cm12.1 snapshot recovery using flashify but I got stuck in a boot loop.
I then flashed the recovery using heimdall and that worked.
I then flashed cm12.1 snapshot using the cm recovery, but that was stuck on the cm logo for at least 4 hours before I shut it down.
I then tried a couple more times and it's the same thing.
I installed other cm11 versions and they all get stuck on the logo (even though I came from cm11).
So I tried a different recovery, the latest version of twrp and long story short it's the same thing with cm roms.
Then I flashed back to philz touch (but I didn't realize that I flashed the latest version) and it's the same thing.
Even after I restored a previous backup, the cm11 rom wouldn't boot up.
At the end I was able to use odin to flash back to stock.
I can also flash rwilco's NE2 based ROM.
I have also tried cyanideL, which is CM12 based and it gets stuck too.

Finally I found the post mentioned above and downgrading to TWRP 2.6.3.0 worked.

Hopefully this post will help someone down the road.

I need your help to check my theory: why many users don't have heat issues!

I have seen many reports on XDA and some other forums that many users have NEVER had heating issues, their Antutu are even over 50k. And I have seen a guy compared his Z3+ with his friend's phone in 100% conditional (preinstalled software, latest 251 firmware, background app, temperature at first,...) and the result is strangely diffirent: his phone didn't have heat issues as the camera was all good (just warmer than Z3 a little bit), but his friend's phone was hot and automatically closed the camera.

As all of you have already known, SONY USED TO FIX THINGS MANY BUG, FAULTS, AND RESOLVE MANY PROBLEMS .... in their later manufacturing weeks product. For example: A Xperia Z1 which was manufactured in late 2013 is hot, yellow-tinted screen, micro-USB protections are easily to be ripped off,.... but all the phones in 2014 and later are not having these issues.

So I think maybe, just maybe (and that's why I need all of your helps), Sony actually've done something on all the Xperia Z3+ that being manufactured on later weeks+, so that's the reason why many of you don't have heating issues or battery like others. This is likely to be happened because Sony actually acknowledged about the heating issues, and I don't think they won't do anything about it since the heating issues have been hurting the company.

So I want all of you to check your phone to me these informations:

Phone colors:
Region:
Cus. number:
Firmware version:
Heating status: very hot or not, and is the camera auto-closed thing still bother you?... more details if you can.
Battery status (SoT...):
manufacturing date:

This is how to check your manufactured week: In the simcard tray, you can see a small piece of paper (look closer), pull it out with a pair of tweezers or anything you can (the same thing I do to remove the sim card tray, my fingers are just too fat for that fiddly thing) and you will find found the information you would find usually behind a battery cover of other phone like Samsung's and such, the IMEI number, other serial numbers and of course, the manufacturing date. Write it down to me as above.
Example: 15W15, this means the phone was manufactured in 15th week of the year 2015 (between the dates April 7th to the 13th).

Thank you very much for helping :)
