Hello, I've ran into some trouble with my nexus 9. After the last update my device seems to be bricked, just stuck on the white "google" logo during start up.
I'm trying to flash OEM android on my device and have been unsuccessful because my bootloader seems to be locked, and the only way I can find online is to do it through developer options which I cannot access now since my device is bricked. I've tried the fastboot command oem unlock and permission is denied. Prior to this I have not enabled developer option or usb debugging because I was ok with using stock software.
I can get into bootloader mode and access fastboot USB but I cannot flash my device due to bootloader being locked!
I've also tried Recovery -> wipe all data, and my device is still bricked afterwards!
Is there anything I can do at this point?
I've been running stock software the whole time! Never rooted / unlocked my device.
Forget about it.
Talk to the vendor (google / amazon / etc) the device is FUBAR
I am getting a new one, since there is no way to fix this.
period.
sorry for everyone affected, but google said, that there is no way to fix it.
damn..just called google and they said they will get back to me next week. this is pretty sad

It seems, I have the same problem. I tried to wipe it several times, it is no use.
Maybe I am completely dumb, but could one not sideload from 5.1.1. to 5.0.2.?
adb sideload <>
is about the only thing that is working. I don't know, how ota-files are created.
Have you tried this?
http://forum.xda-developers.com/nex...-disabling-t2951312/post60702161#post60702161
Put Device in Fastboot mode:
Power and Volume down,
then in the bootloader, go to fastboot.
With the fastboot tool (google), type:
fastboot format cache
fastboot format:ext4 userdata
It fixed it for some users, because wiping the userdata is apparently different from a factory reset in the boot loader.
For me, it did not work out: I did not end in a boot loop but in a neverending boot sequence.
Trying to flash 5.1.1 on my N6; now stuck on colored dot bootloop. Tried fastboot format cache and fastboot format userdata; both fail because the bootloader is locked.
Google has completely ruined this. I've owned the Galaxy Nexus, Nexus 4, and Nexus 5, and I *never* had a single issue doing simple **** like this on those phones. Here, everything fails. All the time. This time it's failed hard enough, evidently, to cause a permanent brick. Thanks a lot, Google.
Hi all, this is my last hope at the moment. Any input would be highly thanked.
I own an ASUS Padfone 2 (KOT49H.WW_Padfone-11.8.4.23-20141028), stock firmware, that I managed to get soft-bricked, as I read they call it.
Phone is unrooted, ran KitKat, and I really don't know much more about it, I'm not really an expert unfortunately... No custom ROM or any of those pro stuff.
Scenario:
Every single app crashed upon opening, performed a reboot, phone got stuck into infinite boot-loop, at the company logo in the beginning.
What can the phone do and what I've done so far (all of which have been found through internet):
I can enter into recovery mode.
Did a factory reset and wiped cache partition before the following.
I entered what the phone calls "CSC mode", that other sources call "fastboot mode".
Followed this guide http://forum.xda-developers.com/showthread.php?t=2256977 , installed drivers, entered into the proper directory on CMD, and typed "fastboot boot recovery.img", but CMD says "OKAY" and all, but gets stuck at "booting...", even after like 15 minutes.
Then, for whatever reason I saw on the internet, I tried the command "fastboot oem unlock" that also didn't finish anything either in CMD or (seemingly) on the phone.
Then, I tried following this guide in CSC mode (even though I don't have the invalid kernel error) http://www.modaco.com/forums/topic/365818-padfone-2-invalid-kernel/#comment-2191432 , but also didn't get any further than CMD stuck at "booting..." for forever.
I suspect it could be possible to do some of those booting magic, but I have no clue how it works and how my problem inside the problem could be solved...
Thank you so much in advance.
(Please beware that I don't understand what the words bootloader, fastboot, flash or ROM mean. I'm a mere mortal.)
Hello everyone,
I ran into this problem while trying to solve another.
The current state of my phone (h850):
On booting, I receive this message: "Your device is corrupt. It cannot be trusted and will not boot."
Fastboot is still accessible.
Download mode is not: holding the volume up button and connecting a USB cable presents me with the above message.
I can still access the "Factory data reset" dialog, but after selecting "Yes" twice it takes me to the above message.
[edit]:
fastboot getvar unlocked
unlocked: no
I tried unlocking the phone again using fastboot flash unlock:
Code:
fastboot flash unlock unlock.bin
target reported max download size of 536870912 bytes
sending 'unlock' (1 KB)...
OKAY [ 0.040s]
writing 'unlock'...
(bootloader) Error!!
(bootloader) Bootloader Unlock key write fail
FAILED (remote failure)
finished. total time: 0.080s
... so that sucks.
Any way to recover from this?
How the hell did I get here?
I had TWRP and LineageOS 14.1 installed. Lineage released a new update which I tried to install from the OTA-Update list. After rebooting, I ended up in TWRP, which did... nothing. So I tried rebooting, only to end up in TWRP again; there appeared to be no escape. Finally, I came across an answer on reddit (I'm not allowed to post outside links... it's on the LineageOS subreddit, post ID is 61nxs6):
for g5 the command are these:
dd if=/dev/zero of=/dev/block/platform/soc/624000.ufshc/by-name/misc
dd if=/dev/zero of=/dev/block/platform/soc/624000.ufshc/by-name/fota

I tried those, and that's how I got here.
Try reflashing twrp.img in fast boot (see Autoprime's AIO post for instructions) then try booting into twrp - then at least you can wipe and flash a new stock/custom rom!
Best of luck!

Thanks for the reply!
Reflashing TWRP doesn't work as the device is somehow locked again:
Code:
fastboot flash recovery twrp-3.1.1-0-h850.img
target reported max download size of 536870912 bytes
sending 'recovery' (19076 KB)...
OKAY [ 0.471s]
writing 'recovery'...
FAILED (remote: device is locked. Cannot flash images)
finished. total time: 0.490s
Unlocking fails as mentioned in my fist post.
did you try flashing stock kdz file with lgup? if it boots you can later try unlocking.

It's my understanding that LGUP requires "download mode" to be active (which I cannot access, see first post). In any event, any mode that I can still reach (error message, factory reset, fastboot) does not cause the device to be visible to LGUP, even using Uppercut.

good point. how about if you try fastboot flash recovery twrp.img or if it fails flash stockrecovery.img?

if flashing recoveries fail, try fastboot flash bootloader stockbootloader.img (you can find these images from stock zip format in the forum)
Thanks everyone for the help! Just to be thorough, I tried entering download mode for what felt like the 42nd time, and whaddaya know, it worked! So I'm currently in the process of returning to the point I was on before I tried that ill-fated update of LineageOS. Thanks again everyone!

what exactly have you done? i have the same problem

To enter download mode:
Turned phone off by removing the battery
Reinserted the battery without the USB cable plugged in
Pressed volume up and kept it pressed
Reinserted the USB cable while still keeping volume up button pressed
(As I mentioned, this didn't work the first few times around and I don't know why. Apparently, persistence paid off.)
To reflash the stock ROM:
Google-searched for this phrase: lg firmware h850
Note: I'm not yet allowed to post links. Your results may vary. There was a result at a domain which includes the words "lg" and "firmwares". That one I chose. Hope that's vague enough.
Also note that there are other sources of this image, I'm sure I've seen something here on the forums.
Downloaded the image H85020i_00_OPEN_EU_OP_0628.kdz (I had trouble with an image version that was less than 20i (10c I believe). Again, your mileage may vary.)
Booted into Windows because (sigh) LGUP, which is used to flash the above image onto the device, is only available for Windows
Acquired UPPERCUT along with the correct version of LGUP and the latest drivers
Started UPPERCUT which in turn started LGUP
Note: this will only work with your device connected and in download mode.
Selected the image mentioned above (click the File path column of the BIN file row if I remember correctly), selected upgrade, started and waited
Had a cup of tea to calm me down after a day's work of messing with my phone
After the phone rebooted, I reset it to factory settings
(you may run into an issue here with a password that you're supposed to enter, don't remember what I did there but as far as I understand it entering it wrong enough times will factory reset your phone as well)
[Optional stuff from here on out I guess]
Unlocked the phone again (fastboot flash unlock unlock.bin)
Flashed TWRP again
Installed LineageOS again
Hope that helps, good luck with your phone!

Not sure what you mean. If you're wondering whether I lost that piece of information: no, it's printed on a sticker on the back of my phone. In general there's usually a sticker with your phone's IMEI somewhere on the packaging or, like in my case, on the device itself.

Again I did the same, bar the tea, but unfortunately my tale does not end quite so happily... Not yet at least. I can "upgrade" with literally no problems using LGUP and one of the few G6 KDZs available, but when it's time reboot my phone always boots into the fastboot for bootloader unlock mode. I can use fastboot commands but my bootloader relocked at some point and I'm still not able to unlock it again. No matter what I do my phone always boots to fastboot... Except when I do the recovery key combination and press "Yes" twice, in this case there's a brief "erasing" animation and then I'm back to fastboot.
I realize I'm using a different device, but would anyone happen to have any thoughts on this? This is my first time using a non-Nexus LG and I must admit I'm struggling a bit to get out of this mess. The recovery and fastboot modes also look quite bare to me, but I might just be using the wrong.
Cheers!

Thank you for your detailed guide, but it didnt work for me yet. I tried maybe 100 times. Everytime the same Message "Your device is corrupted".
You are a life saver
Thank you for detailed tutorial.
My H850, which I managed to almost dead brick, like yours (of course from the same source - reddit ) after few minutes with uppercut + lgup ressurected with all the files and apps inside
So, after that I'm running through factory reset now and trying to unlock once again.
Thank you
Have the same problem but......

I've got this problem also, thanks to those lines put into 'terminal'.
I can get into download mode easily, however by the time I then open Uppercut and try doing anything the phone reboots itself back into the 'corrupt' screen and keeps looping on that.

Maybe unlock.bin is corrupted, try ask LG to resend the file.
