[Q] Nexus 7 (2012) Broken bootloader, apx mode - Nexus 7 Q&A, Help & Troubleshooting

A few weeks ago my girlfriend rebooted my Neuxs 7 but it somehow got in a bootloop. I tried to fix this but i managed to shred the bootloader i guess because now it won't turn on at all.
I've tried to boot it into fastboot, but that won't work, so i'm pretty sure that the bootloader is broken.
When i plug it in to my computer and hold in the powerbutton it shows up as a apx device, which i guess is a good thing in this situation (meaning i havn't completely broken the device).
I'm not very skilled with these kind of situations and really need help from you guys.
I've read about apx drivers and if i understand the situation correctly i could somehow install a new bootloader this way?
Could anyone help me step by step restoring my precious Nexus?
I could send it to service, but i don't think i have any warrenty left on it since i bought it almost 2 years ago. I also suspect it would cost me a lot of money if i send it to service.
Please give me happy answers

Pretty sure you needed to make a backup of your device first to flash back with apx mode as this is device specific

Same problem here.
From what I read the only way to restore your N7 in APX mode is if you had a backup(again from apx mode).But now the device doesn't have(or its broken somehow) a bootloader anymore so we can't do it.
If you still have warranty return it,if you don't buy a new motherboard(40-60$ on ebay depending on the storage) and change it your self.There is plenty of tutorials on the web how to do it.
Good luck.

I believe I have the same issue. Nothing on screen, does not come up on computer but shows as APX. Does back up have to be from our device or can a backup be made by someone and we restore from that copy?

To the best of my understanding it is device specific so for those who want to be safe make a backup now as you can't use someone elses

My nexus tablet 32gb is permanently bricked

Ok I bought this tablet on 4/7/2014 then yesterday which was 4/8/2014 it bricked on me and it wont power on or charge i tried taking the battery out then replacing it that didnt work next i tried the volume combinations that didnt work either i ran fast boot via pc didnt even picked up the tablet my guess is that either the file structure or NAND went bad and i need to fix that so i can use it again if you know a way to get this tablet working then please tell me also i tried many android toolkits none worked im guessing i need to fix the NAND but dont know how if you can help i would really appreciate it oh btw i was running stock 4.4.2 and had an unlocked bootloader at the time its like my tablet is completely empty.
If you only had it one day is RMA an option? Otherwise your looking at a new motherboard. Does anything happen when you plug it into a PC any noise or connection? Usually corrupted nand will turn on but will bootloop and any attempt to flash will fail. You may be stuck in apx mode with a corrupted bootloader but either way it sounds like your up a creek.

Nexus 7 in APX mode

Hi
A few days ago I wanted to go back to stock and used Wug's toolkit to do it, but when it should flash bootloader it got stuck and here I sit with a tablet in APX mode. I have tried every single button combination that I've read about without any results.
Does anyone know how to fix this? In case not, will a motherboard replacement help?
Dont waste your time looking for a "software" or "firmware" fix, just replace the MB. I had a N7 32g stuck in APX. If you didnt do a "flatline" backup or something like that (blob files, etc....) your stuck in APX and can not bring it back. Buy a MB off ebay and just replace it... you will save a lot of time reading endless attempts by others with no success without a backup of your "own" n7. You cant use other backups from different n7's....

Bricked Huawei Nova, please help

Hi everyone
I tried to updade my huawei nova CAN-L11C530B130 to CAN-L11C432B340
I think the copy/paste of the UPDATE.APP ****ed up beacause the transfer time was very short...Anyway the phone accepted the update but turned off after that.
Now I can't boot, no recovery, no download mode, not even a charging led light.
Please tell me there is a way besides RMA
Thank you very much :good:
Well, either there is no charge (try keeping it on charger for a few hours) or it is totally bricked based on what you said. If it is completely unresponsive there is really nothing you can do.
Boot loader doesnt start as well?
Thanks for your help
I tried an all night charching but It did not help, no boot loader either.
What about the version I had : CAN-L11C530, I don't find any results about it on the internet, strange right ?
When I plug the phone to my computer I get "Qualcomm HS-USB QDLoader 9008 (COM3)"
You could try contacting Huawei support, their is a qualcomm flash tool. You need the tool and the rom to use it. I know it worked on the Nexus 5, but have seen nothing like it for us. I would try going to a shop and asking, but I do not know how viable that is for you.
Thank you wangdaning, it's very kind of you
I'm gonna leave the phone to the carrier who will send it to huawei.
I'm just surprised how easy it was to brick, I have a honor 8 and a mate 8 and it never happened.
I wonder if it comes down to it being a defective device. I have run circles of flashing on mine and it does not brick. I am running Lineage and even the build is not for my device. I have manually flashed partitions, wiped and reflashed partitions (in fastboot). I have made it unusable at times, but never bricked. It works fine now. Seems it might just be an unlucky bad unit you got. Hopefully you had all your stuff backed up and hopefully you get a unit that works well next time.

SM-950F Hard bricked, JTAG?

Hey
So I was flashing android 7.0 to an S8 and it completely died, this is how completely:
- No screen/LED/vibration motor
- No safety/recovery/download mode (and don't ask about button combos, I've tried them all)
- No USB recognition from device manager (not even as exynos in other devices, just nothing)
- USB jig does nothing
- It is however recognised by wireless chargers (but I doubt that has any real significance)
At this point my question is would a JTAG even work on it? Or is my only hope a complete motherboard replacement?
S8 Hard bricked

Jtag dead phone to life and rewrite IMEI
I had the same thing, sent it to Fonefunshop in England, they said they could fix it, the didn't even open it as discovered by the guys who fixed it and is necessary to use jtag.
Fonefunshop said eMMC chip was bad, which is not true, but that led me to search for someone to replace the chip. I found A2Z cellular in Ottawa, Canada. They got the phone to boot up, but IMMEI was null( I did this trying to flash back to stock after TWRP screwed up). They rewrote original IMEI , now phone works like new. These guys are amazing.

Thank you all for the advice.
But I have now managed to unbrick and reflash the firmware. khawarjaved's advice turned out to be what fixed it in the end.
That was close, nearly lost £30

I have been through that situation man.... So always ready to help, ??
Hi pros
I'm in kind of a similar situation....I think I flashed MY 950U PIE with wrong BL
This phone is dead....Doesn't boot...no download mode....No recovery mode....
When connected to pc....device manager Recognises device as QUALCOMM HS USB 9008
Any way to brig it back to life...?
Your phone is connected in edl download mod. It will accept special files which will allow it to boot to download mode and let you flash stock firmware
The tool used for this is emmcdl.exe
It has to come with phone specific files
No idea where to get it. Ask people here, those who root phones. They know.

Hardbrick on Samsung J5 J500fn What options are?

Phone was hard bricked using standart program Odin, it was bricked because i added 1 flash file needed, to 4 sections BL,AP,CP,CSC same file for each section, it's supposed to be only at AP, and its flashed with green PASS, what is surprising to me that nothing prevented to flash it, after it pass, phone black screen, no recovery or anything, just common hard brick "qhsusb_bulk" thing.
I tried load recovery from microsd 32gb, but nothing happens at all, still black screen, maybe i need correct debrick image?
What other options are for this phone?
Sorry to not have any help but I've done the exact same thing as you have to the exact same phone. Ticked all four sections in Odin instead of just AP. Got the green PASS and then the phone went dead. I must have misunderstood something in the instructions I was reading but it was too late. D'oh. Hard brick. I've been messing around with debrick files trying to get it to boot but not having any luck so far. I was using Odin in the first place to try and bring my phone back from "Custom Binary Locked by FRP" which randomly happened to my phone when I put it on after not using it for a while, never used any root stuff before now (the only other person I could find online who got the FRP error without rooting anything had eMMC failure, so my phone could be toast anyway.) I'll come back here if I have any luck with the debricking files.

This is basicly exactly my situation you mentioned from Odin to FRP lock screen 1:1 match, i was thinking that eMMC failed to, becouse tried Sdcard method, qfil flashing, absolutly nothing works, last thing im waiting to try is usb JIG i ordered, if you find any information or do any progress, be sure to share it, i will do it to if i find anything success, but if JIG wont work, than i suspect that eMMC failed, or phone have liquid damage somewhere, becouse USB sometimes disconnected randomly multiple times, and show Unknown device error on win10, also i took phone to repair shop, said i need reflash becouse bricked, he didnt fixed to, maybe not experenced at that,only things like replace screens
Well, I'm sure you, like me, have made absolutely zero progress on this device since nothing seems to work with it. The J5 SD cards don't work, you can even make your own debrick from a stock rom, but these didn't work for me either. No response at all of any kind to any SD card.
Presumably it should work like in this video, the LG here isn't responsive to anything, shows up as "Qualcomm HS-USB QDLoader 9008" then the SD card goes in and BOOM, device back. Also, that guy seems to be in the "old QDLoader mode" just like us so in theory I don't see any reason for the SD card to not work, maybe we just haven't found the right one?
Annoyingly, if Samsung ever released their files like the firehose (which I doubt they would) or they got leaked, then QFIL would work. But as it stands we don't have those files so we can't do anything with QPST/QFIL except see that it's the only thing that can communicate with the J5 in that state.
I'm not sure what a USB jig does, but looking on Google it seems like it just simulates button presses to hold the combination for Download Mode?

Im still researching, i even used same method to make own debrick image, i tried multiple versions, latest 6.1 android, than latest 5.1 android, even tried first firmware 5.1 released, still absolutly no reaction to phone, not even vibrate or anything, tried press multiple times button combinations, tried few SD cards, 32gb with 10speed, absolutly nothing at all, looks like we are on exactly same situation, im stil trying things, now probably will be USB jig, combination with MicroSD, im just waiting on few USB jigs i ordered, for few dollars, its usefull to have anyway for other situations, so if i found any sign if life i will definetly share here, becouse if my would work, definetly your would work to, i have no idea why its does absolutly nothing, i tried even diffrent battery from other phone, still same, and before i tried use Qualcom flash QFIL, try flash some unofficial firmwares, but looks like Samsung phones not very good at that, only LG or others its designed for that, basicly no infomation about Samsung phones, even no repair services online.so if you find any progress be sure to share it, i would definetly do it, if i discover anything.
I have the same problem as you. My sister was using a Samsung Galaxy J5 (2015) and the battery was growing bigger meaning that it could be dangerous. So we left that one smartphone in the corner without a battery. Well, after my Nexus 5 had a problem too, I decided to get back to my J5 that I gave to my sister. I had to buy a new battery for it so I did. When the battery arrived, I tried to turn it on, but it wasn't turning on. I connected it using a USB cable in my computer but instead of displaying the device's name, it displayed as QHSUSB_BULK. When I was asked to install drivers for the device, I did so, and the name changed to Qualcomm HS-USB QDLoader 9008 (COM8). I went it to a repair shop and they said it might be the freakin' screen!!! I mean, what? People all over the Internet having the same issue with me say that it is a hard brick. Hard brick has NOTHING to do with the screen, correct me if I am wrong. I also saw somewhere that I can only fix my device if only I replace the motherboard entirely (because replacing specific part of the motherboard is kind of dangerous and can cause even more problems...) I have no idea. I need help. I want to try flashing firmware with my SD card, but I have no image for my SM-J500FN device. I feel hopeless. They encourage me to buy a new smartphone. Something "modern". But what I know is that today's devices are more "brick-able" that those of old times. I want to install TWRP Recover again and finally root my device. I know how to do that to my Galaxy J5, but I can't do that when my smartphone is not turning on at all. It doesn't even vibrate!!

Im sure its hardware failure, nothing can be done, i tried alot things, nothing worked, not even small progress, phone just dead, tried usb jig, tried to use every recover image from all firmwares, nothing worked, only fix to this phone is replace motherboard, but to access motherboard you need remove screen first, i give up on this phone, not worth time, tried everything, ether motherboard replacing or just get new phone

Well, they suggest me to get a new smartphone because if I get to replace the motherboard it will be too expensive and maybe not worth it... I guess I will have to give up too, even if I loved that one... Thank you friend.

Probably happened same thing like to you, i received phone from female, who used daily, it was already had this issue, definetly she didnt do anything software related things like flash, so im guessing hardware failed, thats why nothing you can do, only fix is most likely motherboard replacement, but at this point is not worth it, becouse will cost half phone price, so i rip"ed this phone, writed it off, its laying for parts, did what i can, tried all methods, usb jig worked on every samsung i have, s5, j5 2016, but execpt this one, this means is definetly phone dead, also tried to recovery with microsd, every single firmware, from 5 android to 6, all versions, created recovery, and none of them worked, also tried on few microsds, and absolutly was no progress, not even vibrate, dead entire time
