[Completed] Nexus 7 Stuck In APX Mode After Trying To Flash KitKat Stock ROM

Hello everyone,
My first time in this site and been reading a lot of posts. I wonder if anyone can help me out with this problem.
I was dusting off my old nexus 7 in order to use for college. The current lollipop versions brought the speed of the device way down. I been reading that plenty of people have the same problem with the new version. I went searching for a way to revert back to kitkat so my tablet can be usable again. Anyways after reading and watching videos I found a good one. I would post it but since I am new tot the forums it restricts me. I followed it step my step even downloaded the correct nexus 2012 wifi kitkat version but when I was flashing the device on the command prompt it kept saying telapia folder was not found. I made sure the file was placed correctly but was still giving me the error. Then I made the mistake of unplugging the usb cable then the tablet shut down. Now the screen won't turn on and under device manager it shows the device as an "APX." I know the physical hardware isn't damaged because I can here the ding noise when I plug the tablet to the computer. Please if anyone has a step to step guide to recover the device that would be awesome. Thank you.

[Completed] Huge mistake! Please help guys :(

Hello everyone, i'm new here so..sorry if i post this in a different place, but anyways..
i'm using Infocus M2 4g, i'm really happy with it, but yesterday i decided to install an android 5.0.2 custom ROM, maybe i forgot to wipe cache and make a factory reset before installing it, now my phone works till the welcome page, and the screen touch isn't working, and whenever the screen turns off, the device reboots again and keeps doing it over and over, i don't have a custom recovery, i flashed the ROM by a tool called DinDong and it requires usb debugging so that i can install a different ROM, and get rid of the problem, i can get to the fastboot screen, but i can't flash a room trough that :/
so this means .. NO Custom Recovery, No USB debugging, .. nothing :crying:
i would really appreciate it if you guys could help me, i have so many friends that i want to talk to again on whatsapp, and i don't want to use bluestacks again i need to get back my phone working,
thank you so much for reading this, and please reply as soon as possible)
and sorry for my English

R7 PlusM doesn't boot properly anymore

Hi there, I have tried to find a solution today for this issue but I can't find anything useful anywhere .
Last night I received another update via OTA 151115 and proceed to install it as the earlier ones didn't work. Surprisingly this one worked and after restart my phone didn't had any trace of google apps on it, try to install google play, framework and so but the phone says it's not compatible with google (Big time). Then I went to the bootloader to perform a wipe/erase everything and here's when the problem began, it was stuck in the screen that says optimising applications (the one before starting the setup) and after half an hour unattended the phone restart itself one after another, like in a loop.... From this point on, I haven't been able to power on the device anymore.
It was bought through a third party seller from China, already contacted them and waiting for an answer...
Any clue about what can I do to use my phone again?
Update: I can see the oppo logo after pressing volume up plus power buttons for around 15 seconds but it shows for less than a second the screen it appears when it's updating the software and then it switches itself off... Is this a sign of possible recovery in some way?
just downloaded the last 151115 official update from the oppo community forum but I've got a problem. I can not enter the fasboot or recovery mode because the phone is like trying to install something and it constantly switches itself off... The day this happened, I had two files in my root directory, one was the few update and the other was a full Google thing in the same format than the fw file, I'm afraid I selected the wrong one and that's why the phone went crazy. I guess if there's some way to cancel that attempt to update the wrong file or reset that thing in some way, I'd be able to start over but I can't find anything grgrgr
By the way, the last ota update allowed google maps to work flawlessly and also Instagram, two of my biggest concerns with the phone
I'm even trying to contact oppo service to send the thing and sort it out that way xx
Cheers
Pedro

I've just contacted Oppo Customer Service in Europe to see if they have any solution for my problem as I can't make this thing to start and the battery also doesn't seems to be charging though... No response for the moment, just an automated one confirming the reception of my enquiry
Should I start thinking about my lovely new phone as my new paper weight?

No, no you have a chance to save your phone. If you have to R7 plus M Oppo Chinese version, I can help you. I also had this problem, but he was able to solve it. My Skype: ed_mobstyle.

Hi mate, thanks for the answers. Yes it is the China mobile version "M" I don't have Skype I'm afraid grgrgr
Cheers

I was able to fix this problem fairly easily.
First I entered recovery (press Power + Volume Down when the phone is booting up)
Then from the device menu I installed a ROM, you want to download the version you last used. (MAKE SURE IT IS FOR THE OPPO R7 PLUS M)
After installing the stock rom, it will go into installation and have you set up your phone.
After you installed the ROM, download OPPO tools v 1.6.5
Open Oppo Tools and root your phone this will take a few minutes.
After you have rooted your device open Oppo Tools again and select Unlock Google Mobile Services (this too me two weeks to figure out).
Let the phone restart, after it is finished, you should have basic google functionalities (Playstore and Frameworks).
Now since you are rooted, it means that your phone will not download any further OTAs and you will have to install them as ROMs, you can do so by repeating the above process, but I'm not sure of the functionality of Oppo Tools past the most current version.
I cant post links to provide you to where the ROM files and Oppo Tools are at this moment
The roms will be located on the "[ROM][STOCK] Official R7 Plus Roms | R7Plus, R7PlusF, R7PlusM [15 Sep 2015]" of Oppo Fourms
The Oppo Tools will be located when you google "OPPO Tools apk" on your computer and it will take you to the thai version of Oppo Fourms follow the link there to download the apk

Hi mate, thanks for your answer but my problems is that I can't enter the recovery mode cause the phone try to install something and then it switches itself off
I've tried to connect the phone to my laptops and sometimes they recognised it as Qhsub something and I can't find anywhere this driver. Then all the softwares I've got ask me for a scatter file which I don't have....
Also trying to contact support from the brand. For now just send them my data and the phone's imei and now waiting for the magic response... They are excessively slow in their answers!
Thanks so much anyway
Cheers
Pedro

Still at the same point mate! The thing keeps on trying to install something and switches itself off. My windows laptop runs on win10, the other is a Mac so I guess useless for this matters... The battery runs out faster than ever even being off. Disaster! Lol
I would really appreciate your help

Hi mate, my problem is that my computer detects the phone as qhsusb_bulk and I've tried every single file I found with that name and nothing changes, well, the device name from unknown to com1, com2... up to com13 I have seen.... Other thing is that I can't enter the fastboot mode or recovery mode neither. I wish I had an oppo service near home but I live in Uk, now I'm trying to get service from oppostyle and waiting for an answer. To be honest with you, I'm really annoyed with all this, never had a problem with bricked androids or iphones until I met this "guy" lol
Cheers
Pedro

I'm really sorry dude I hope I can help you as I did for mine it was quit simple with the same driver problems,so try to uninstall all drivers you have for oppo and install the one I shared with you taken from my ohone directly that the only way you can give any commands to your phone to switch to fastboot mode even if the problem still present

when I try to install the driver on my win10 laptop it says this...

Using an old win7 laptop I managed to install the bloody Qhsub driver and now the phone appears in the com ports under the name Qualcomm HS-USB QDLoader 9008 (COM4) does this means the phone really doesn't exist?

Update to this thread, I can't do anything until I find a proper driver for the phone which actually is recognised by my laptop as Qhsub_bulk and I can't bloody find this anywhere at least for making 6795 processors or specifically for this model...
Any clue?

BRICKED MY DEVICE!!! Please HELP!

Hello good kind hearted fellow reading this,
I was trying to root my Old NVIDIA Shield tablet LTE which I foolishly updated to 6.0 so I could remove the tegra.OTA apk and prevent the kill switch.
I first followed the instructions in this thread: http://forum.xda-developers.com/shield-tablet/general/how-to-root-nvidia-tablet-android-6-0-t3280671 then lost Wifi.
I then decided to follow the instructions in this thread: http://forum.xda-developers.com/shield-tablet/general/unofficial-update-original-shield-t3281541, then after step 3 where I flashed the blob.img, I rebooted the tablet as directed, but now nothing happens. It won't come on so I can proceed with the procedure, It is not recognised in ADB, It only shows up in my device manager as APX when I plug it in and shows the green/orange light which indicates charging. The screen remains BLACK>
The bootloader is already unlocked
Is all hope lost??? Is there anyway to revive this? PLEASE HELP ME...
I have read through threads which i searched for using the keyword "BRICK", but I dont seem to be able to find anything that can help.
Thanks a bunch!

Just call NVIDIA and talk to them. If it's only a software problem (flashing gone bad), they can fix it in 10 minutes. As far as I can remember somebody in the first thread I linked, talked about returning the tablet for repair after talking to them.

Lenovo S856 China Unbricking tutorial

Problem: You have purchased a China Lenovo S856 smartphone and tried to flash ROW ('Rest of World') firmware to it for whatever reason. You now have a softbricked phone that won't boot past the Lenovo screen.
Solution: Download the following files, which are a little tutorial with pictures, as well as the correct China firmware for your s856 and the Flashing tool to use....https://drive.google.com/open?id=0B6knvSQRiKPzQTMtaXFXZEFNbHc https://drive.google.com/open?id=0B6knvSQRiKPzRTk4ZTB3c1VDdzA https://drive.google.com/open?id=0B6knvSQRiKPzWVA2UENuY1NYTkk
All the solutions I have seen so far were sketchy at best and very difficult to comprehend, let alone use to unbrick your phone. This is what worked for me, and my attempt to help anyone else with the above problem.
That is all, and good day to you.

Thanks for your help, but my problem looks very difficult now, because the system cannot recognize the phone and the phone refuse to boot on. What do you advice?

Hello...
My system did not recognize my phone, either. Nor would it boot up... it was bricked. This tutorial is for people who are exactly in your situation. I would suggest downloading the files I have uploaded, and reading the tutorial.

Finally got the process started,...but after 7s I got and error message Reached the end of the file.(0x80070026: Receiving hello packet)
Could it be my PC (win 10 32 bit) problem or what do you think?

This happened to me as well, the first and second time I tried the flash. There is a trick which worked for me... I pulled the battery out and put it back in and while holding the volume 'up' button, I plugged my phone into my computer usb port and let windows install the driver. It took a few seconds and then I clicked 'refresh' on the Miflash window, which I had left on. At this point the 'flash' button became available and I clicked on it. This time the flash was successful. Try it.
