First up:
My 5x was rooted and working for 6 months using the amazing step by step posted at: http://forum.xda-developers.com/nexus-5x/general/guides-how-to-guides-beginners-t3206930
It has TWRP custom recovery which I can no longer access.
The only mode I can access is the bootloader using fastboot.
Google has already sent me a replacement but I would like to get as much of my non-backed-up info from the internal memory as possible before returning it.
The phone functioned perfectly in its rooted state for 6 months until one day on vacation when it kept rebooting at random intervals where the intervals got shorter and shorter to the point where the phone was simply unusable. Now it does not boot at all.
Even a week ago ago I was able to go into TWRP once out of 25 tries but now that does not work anymore either.
If you let it try and boot, it will display the "Your device software can't be checked for corruption.... please lock your bootloader..." message. It will then display "GOOGLE" on a plain black screen with an unlocked padlock in the bottom. It will loop between these two screens over and over without every going into the android startup animation screen.
I have reflashed a new stock image from the google repository as well as a new recovery - all of which completed successfully per the messages at the command prompt screen. However this did nothing to fix the actual issue. Same exact screen and bootloop.
At this point I would be happy just to be able to go in and access the information in the two users (I had multi-users setup). Since the bootloader is the only mode I can enter, is it possible to access the internal memory using fastboot? Thanks in advance.
Did you flash the full factory image? It would have deleted all your user information?
Even if not, you would need to access from something like TWRP as the user partition is encrypted, even if you have no password set up (it is encrypted with random password, which itself is then obfuscated by encrypting with known-text)
You could try booting TWRP over USB using
fastboot boot twrp.img
But if I recall correct, twrp has a bug where it can't decrypt user if booted in this way, but I don't remember if that is for pattern/pin/password or even with default known password.

Thank you Sfhub. Just tried your recommendation of booting TWRP over USB. Still the same issue. The device restarts but never goes into recovery, just loops over and over. And no I did not flash the full image so as to protect the user data still on the device.
Nothing else I could try? Anyone?

It just sounds like your EMMC is dying or dead and whenever something tries to access it, the kernel panics and reboots.
https://dl.google.com/dl/android/aosp/bullhead-mtc19v-factory-f3a6bee5.tgz
Extract the archive and archive saved in it, then try flashing these images:
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash vendor vendor.img
and then check if the phone boots. You will not lose data.
No luck :/ but thanks przemcio510
I left the phone alone for a few days and came back to find a weird message saying the encryption process was interrupted and as a result all data is lost. That I should reset the phone to factory conditions to proceed. I am unable to replicate this screen back.
And the bootloop continues...

If the EMMC was dead, would adb or fastboot complete flashing successfully?
What is your bootloader version? Try reflashing it from fastboot. If it fails, then I have no idea what's wrong.
You could get the message that it completed successfully. Try locking your bootloader, fastboot oem lock. Then reboot to the bootloader. If it doesn't say locked them the emmc is bad.

I don't know if fastboot does error checking. The OTA should be doing error checking.
One issue is the problem area of EMMC might not be the system/vendor/boot partitions.
It doesn't need to be catastrophic failure where everything is affected. It can be partial failure.

If you re-lock your bootloader, that wipes userdata now as well.

hi all,
i've managed to get my g-nex (vz lte) pretty badly bricked and am hoping that someone here will be able to help. here's what i did initially on the phone:
1. ran 4.0.2 update from carrier
2. installed adb sdk etc on win 7, verified connectivity and function
3. oem unlock
4. rooted phone
5. installed apps, etc.
6. used phone for a few days, rebooted at will, all working as expected, no issues
7. fully charged phone and in the settings kicked off the encryption process, entered PIN, everything looked good.
8. this morning i woke up to a failed encryption (unfortunately i didn't catch the error message) which needed to be rebooted to move on.
9. after choosing reboot, the screen went very strange - it had grainy horizontal lines that shifted in color somewhat and got dim
10. after waiting for a bit without anything happening, pulled the power and battery
11. the phone rebooted into fastboot, couldn't get into recovery to restore cwm backup, couldn't really do anything
phone shows the following:
fastboot mode - no boot or recovery img
product name - tuna
variant - toro
hw version - 9
bootloader version - primekkk15
baseband version - i515.ek02 cdma - i515.ek05
carrier info - none
serial number - XX_redacted_XX
signing - production
lock state - unlocked
here's what i've tried:
adb commands - doesn't show as there from adb devices
fastboot commands - shows up with fastboot devices, flash commands seem to start but never stop
ODIN mode - connects but writes fail to complete
different usb ports/cables, doesn't seem to make a difference
what i've found to somewhat work - but not really do much - is to oem lock and unlock the phone, once there i can fastboot flash boot boot.img, etc. but if i do a recovery and try and boot into it, it just hangs at the google screen (with the lock unlocked).
i would like maybe reformat the phone completely and reinstall, i've tried the fastboot -w and erase boot / recovery thinking that i could write a clean image to them once they had been cleared, no dice.
if anyone has some suggestions, i'd really appreciate it.
take care,
philo
Have you tried a clean install of the factory image found here? http://code.google.com/android/nexus/images.html#mysidicl53f
i have tried going back to factory, unfortunately that set of images didn't work either. i was able (after an oem lock/unlock) to flash the img files, but it errored on the fastboot reboot-bootloader command with the oddly lined screen. i've attached a picture of the screen for reference.

I hope you flashed the LTE version and not the GSM
You need this one https://dl.google.com/dl/android/aosp/mysid-icl53f-factory-65895fa8.tgz and you must first flash bootloader then radio and then the update img
i have been using the lte, same as your link. i can get the bootloader on, but a reboot-bootloader gives that weird screen, if i try and flash the radio without rebooting i get:
unknown partition 'radio'

Check here http://forum.xda-developers.com/showthread.php?t=1392336
Its the cwm for cdma edition.Check if you can flash it and in this way have access to cwm recovery
i've tried that as well, same lines even if i use the menu to go to recovery after flashing rather than reboot to bootloader first.
So long as it's back to stock, and you've locked the bootloader, it's off for a replacement you go if it was me

+1 to this
interestingly, i can't get the fastboot oem lock to take either. it reverts back to unlocked after the reboot fails and i have to pop the battery.
does anyone know how to straight up repartition/reformat the flash? i'm assuming that the failed encryption of the flash has put it into an unusable state and would be happy enough just wiping the damn thing clean...
It looks the encryption screwed up because of the different recovery partition which might of also messed up the partition table.
Best bet is to plead ignorance and get a replacement phone.
problem "solved"
i called samsung and pleaded for the pit + factory image with no luck, so i went over to my local vzw and had them replace the phone for me.
i'm not going to try and encrypt this one, hopefully this was just a fluke and won't affect anyone else...
nice work... let them try to fix that shiz!
Darn, I was hoping for a solution...
I am having a similar issue with a Nexus 5. Phone was working fine, started the encryption process and went to bed and woke up with a bricked phone. I can get into the Bootloader and had figured no problem, I'll just do a factory wipe. Whether trying to boot the phone or get it to do the factory restore it sits there and bootloops with the Google logo. Wish programmers would put in status messages the way we did in the 'old days.'
I was able to get a little further was able to reflash, format the partitions etc. but no luck. I am wondering if perhaps the user data may have an indicator or flag that states it is encrypted even though it isnt at this point encrypted. Figured the factory restore would have been more than enough. WUG makes a nice Root Toolkit that automates a lot of the process but even letting do what I already didnt help.

Yep , if you can get into recovery , you can adb shell , then list the partitions with "cat proc/mounts" , from there you'll have a list of your partitions and you can use the ext4 tools to manually repartition . I believe the command is makefs_ext4 <whatever partition you wanna do > I'll try to find the exact command but you can do it .
Also if you simply type "fastboot " when at the bootloader it'll give you the help text and it should tell you how to wipe partitions from fastboot

The same issue here ! memory locked
I ve got the same scenario on a phone i just got , brand new but with the same issue , this one boots up but its impossible to factory reset it , odin , cyanogenmod , fastboot adb flashes .... everything fails somehow .... once you reboot the phone everything comes back ! stock software with the applications and old data .... theres no way to erase it ... it seems the previous owner of the phone encrypted it and then used clockworkmod or something like that ..... the nand on the device is like hardlocked .... doesnt let you do anything !
So, I was using my Nexus during my class today and it was working great.
After class, I walked to my next class with the tablet in my hand, I did not drop it or anything, when I got to my next class the lock screen was unresponsive.
I was still able to take a screen shot, so the tablet wasn't frozen, but the touch screen was not working at all. All of the hardware buttons worked fine.
I let it sit for about 2 hours and the problem persisted.
I just did a soft reset, holding the power button down for 10 seconds, and it shutdown and rebooted, but its now stuck on the Google screen.
Anyone know what is wrong or how I can fix it?
Thank you

Have you tried entering bootloader?
[Info] Guide to entering safe mode, bootloader, stock recovery
I really doubt you are in bricked mode or it wouldn't even show google. If it is stuck on google it is having trouble loading the OS.
Most likely you can go into fastboot mode and just flash your /system and it will begin working again with no loss of data.

Did you specifically try to get into bootloader mode using the post I mentioned.
You need to Press Power+VolDown continuously until the bootloader menu comes up?
The fact that you are getting to the Google screen at all means your bootloader is still working so I find it hard to understand why you wouldn't be able to get into bootloader mode.

Well since you are getting stuck on Google, that means your ROM (/system) is not loading.
I would flash boot.img and system.img from the factory restore.
http://developers.google.com/android/nexus/images#razor
The restore is in .tar.gz format and within the tar there is a zip file. Within that zip file is boot.img and system.img. You need to extract those (ungzip, then untar, then unzip) and place them in your adb directory.
Boot your tablet into bootloader mode, connect the USB cable, make sure it is recognized as android bootloader interface.
Type
fastboot flash boot boot.img
fastboot flash system system.img
assuming no errors
fastboot reboot
If on the reboot you still get stuck, push and hold Power for 30-60 seconds and try again.
Fails a second time, something more serious is probably wrong.
If you get stuck on X instead of Google, that means something may be wrong with your user data. Try the 60 second reboot thing again. If it is still stuck on X, boot into recovery and do a wipe data factory reset. See previous post for how to get into recovery.

You don't need to enable USB debugging for fastboot mode.
You just need to press Power+VolDown until you get into the bootloader. That is fastboot mode. It will install Android Bootloader Interface (usb debugging does android debug bridge interface)
I actually didn't realize you weren't unlocked. If that is the case, the unlock process will erase your userdata, so you might as well just do the full factory restore.
First goto bootloader mode using Power+VolDown and connect USB, type
fastboot oem unlock
You'll see a question on the tablet screen, Press VolUp to go to yes and Power to select.
On the command prompt in windows, you should see it erase userdata and cache.
On the bootloader screen it should have "Start" highlighted (if not, use VolDown to cycle until you see "Start"). Press Power to accept. You should see Google, then it'll go into recovery and format userdata and cache. It'll then try to boot and since /system is having issues, you'll be stuck in Google again.
Go back into bootloader mode, hold Power+VolDown for a while until you see the bootloader screen.
Now grab the factory image as above, gunzip, untar, and you should have a folder razor-jss15j
Copy these files from your adb directory to the razor-jss15j directory
adb.exe
fastboot.exe
AdbWinApi.dll
AdbWinUsbApi.dll
In command prompt in the razor-jss15j directory, type
flash-all
It should output a bunch of stuff, essentially writing a factory image to your tablet.
When it is done, it'll reboot and hopefully you'll get the initial setup window.
I wrote this up from memory, so hopefully I didn't forget stuff. If something doesn't seem right just ask.
Thanks for all of your help.
It really means a lot you took the time to help me.
I'm going to Best Buy today and I am going to see if I can do an exchange.
If not, I will try this later.
Again, thank you
My Galaxy Nexus reboots a few seconds after starting up. I don't have anything other than stock installed and I've tried following several guides here trying to flash it myself since the built-in recovery mode wipe data/factory reset does nothing.
I did notice something strange which following a guide, when I oem unlock and reboot the fastboot mode it locks itself again like I didn't do anything at all. This was a problem when I was using the Android Toolkit too but I managed to over ride my own fastboot oem unlock commands in between its batch file commands and got to an error "FAIL Exceed Buffer Size"
I believe if I can fix or know what to do with that error I can successfully bring my phone back to factory defaults I just don't know what to do! I tried looking for the error on this forum and it came up with 0 results and google isn't helping much either.
I'd appreciate any help regarding this, even if it means my phone is beyond repair I just want to know!
Thanks guys!

best advice,flash back to stock,root the phone,and use bootunlock on your phone to unlock it,it wont wipe your data,then download a recovery.img and flash it with the flashify app,almost everything done with apps and no data loss.

i mean not using toolkit,using actual fasboot. BTW: do you have a custom recovery? if so you could just adb sideload & if you can get the phone into fastboot mode and just flash a recovery then adb sideload after wiping all partitions && did you try using odin to flash back to stock (i dunno if there are odin images available,i apoligize if not)
Hey all,
I was on android P and wanted to go back to Oreo so i booted twrp and wiped system/data and then afterwards, fastboot is giving me errors and i cant even boot twrp to my phone it just says remote: unknown command. Heres a pic https://imgur.com/a/odn4w

Hold the power button while at no command. Then hit volume up and release both. That will give you the menu.
Get rid of minimal adb and fastboot. I don't understand why people are using something made before even the original pixels were released. It doesn't understand dual partitions or handle the larger sizes of our partitions. Get adb and fastboot from Google.

Just curious, but when your in the OS, and open a command prompt on the platform-tools folder and type...adb devices...do you see your device ID?? Same thing for when your in bootloader mode and type...fastboot devices...??? ?
did you fix this? im in the same boat, on p beta tried to flash factory image back to 8.1 and getting "target didn't report max download size".

OP, have you managed to solve the issue?
I ran into a lot of trouble updating June OTA and had the same error. Tried to change ports, USB cables, etc. and just when I was about to give up, I decided to restart my PC and tried again, this time things worked fine without any issue whatsoever.
This is likely not your issue, but if your computer has less than 4 gigs of RAM, or you are trying to flash a file larger than your available RAM you will get this message.
This (i.e. rebooting PC) worked

Hi all,
I installed TWRP on my Honor 7x, that went well.
Yesterday I decided to try to get Lineage working so:
- I installed EMUI 8, that went pretty smooth
- I installed Lineage OS 15.1. (without GApps)
- I flashed TWRP.
The issue I have now is that:
1) I can't install any APK in Lineage. Probably needs a factory reset/dalvik cache wipe.
2) I can't boot into TWRP. It stays stuck on the splash screen forever. This also means I can't install OpenGapps, SuperUser access (afaik), or anything else that requires root.
3) The bootloader is saying "FRP: Locked", which means I can't flash a new TWRP or a different ROM. When I try it fails with "command not allowed"
3) "fastboot oem unlock" fails saying I need to enable it in the developer options, but it's grayed out in the developer options because it's already unlocked.
4) I wanted to try the "dload" method but I can't find a good explanation on how to do it, and Huawei recently took all their downloads down, which means I can't find any UPDATE.app even if I knew how.
5) The other solution that *might* work is using "fastboot oem frp-unlock", but I need an unlock code for that (I assume the same one that you request for an OEM unlock from Huawei), and Huawei closed down the site that generated the codes.
So I'm stuck in a weird limbo where I can't move forward (install Gapps and use my phone as normal) nor backwards (go back to EMUI8).
Does anyone have any idea how I can fix this situation?

Hi all,
I installed TWRP on my Honor 7x, that went well.
Yesterday I decided to try to get Lineage working so:
- I installed EMUI 8, that went pretty smooth
- I installed Lineage OS 15.1. (without GApps)
- I flashed TWRP.
The issue I have now is that:
1) I can't install any APK in Lineage. Probably needs a factory reset/dalvik cache wipe.
2) I can't boot into TWRP. It stays stuck on the splash screen forever. This also means I can't install OpenGapps, SuperUser access (afaik), or anything else that requires root.
3) The bootloader is saying "FRP: Locked", which means I can't flash a new TWRP or a different ROM. When I try it fails with "command not allowed"

small chance you enable root from developer options. (i think it will be adb only)
if so , maybe can use adb shell and "dd" to write recovery to correct partition.
problem is many of the available twrp do not boot on custom rom .
example code. (if you do wrong , it may be bad)
Code:
dd if=/ext_sdcard/twrp_Recovery_ramdisk.img of=/dev/block/mmcblk0p32
It seems like I'm allowed to use dd in ADB shell, but before I run it, what do you mean by " problem is many of the available twrp do not boot on custom rom . "? I thought recovery was independent of the ROM? And does it mean flashing twrp like that could brick my phone?

Like what you have , twrp stuck on splash screen
I managed to unlock the FRP with DC-unlocker. Sucks that it costs money but it worked!
Now Im stuck in a TWRP boot loop though.

At this point you should have access to fastboot though, right? I'd try a different TWRP instead. Perhaps try this one: https://drive.google.com/file/d/1ZYo7Ndte3vlLcUSadD6jIgfBi1oxa0Pb/view?usp=drivesdk
Just to clarify, it gets stuck on TWRP splash screen. When I turn off the phone, it immediately boots up again into TWRP. I tried getting into fastboot mode with all kinds of combinations of button presses, but no luck. Not even Volume Up + USB cable works

Sorry, only saw your answer after sending my other reply. In theory I should have access to fastboot mode. However, everytime I start up I get into TWRP, which doesn't work. I tried Volume up, volume down, both, with and without power button, with and without cable, and no dice.

I have seen this happen before , solution was to wait for dead battery, or disassemble to unplug battery

This is because after the frp unlock, it needed to see a factory reset, and it usually needs to be done with stock recvery.
So will have to wait till battery is dead and and plug in usb while holding volume button. Should then load to fastboot. Where it is best to flash stock recovery to clear the recovery bootloop. The bootloop is do to the fact yo unlocked frp and now phone needs to wipe/data

it sucks this happened to yu but im glad i am not the only one that dc-unlocker deleted my fastboot after i unlocked the frp and i cant boot fastboot for nothing if you find a solution please contact me. my phone is doing the exact same thing booting straight too twrp no mater what combinations i use

i just took mine apart and discconected the battery and still no luck that program deleted my fastboot
Please can you tell me the process to install twrp I have the L24
I waited all the way till the battery drained, stuck in the USB, and it booted to ROM! Sadly it immediately shut off again because the battery is dead (even with keeping the USB in). I'm going to keep trying though.
I can't get into fastboot mode. I can get into the ROM by letting the battery drain completely on the TWRP splashscreen, and then sticking in the USB cable. However, no button combination or "adb reboot bootloader" or rebooting to bootloader from the ROM brings me to the bootloader. I wonder if it's still there. Any ideas?

Seems to be a f-up situation either way.
You have adb DD available, found out before.
Don't know if maybe flashing stock recovery is good idea at this point.
I think fastboot.img can be flashed with DD too, but don't try till someone can confirm.
If flash stock recovery clears the loops, maybe best to do full-ota manual flashing.
I managed to get an UPDATE.APP file and extract fastboot.img from it, as well as all the other .img files. If someone can tell me what to flash and how (with dd), I think Im set.

Fastboot.img is the large part the bootloader. If flashing it goes bad, might be dead phone after, just rember that.
Will add a list of partition names and command s for you soon.
here is a list of oreo partitions and there /dev/blk/** number
and here is an example of code to save images with dd assuming you put the images on your extrnal-sdcard in folder called oreo-images
Code:
dd if=/dev/block/mmcblk0p5 of=/mnt/ext_sdcard/oreo-images/fastboot.img
Do that save first and compare the md5 of the file from update.app to this file.
or just check the md5 before making the copy
Code:
adb shell md5sum /dev/block/mmcblk0p5
If you are conviced you need to flash the images, here is example of writing the image assuming files are in sdcard folder oreo-update-images
Code:
dd if=/mnt/ext_sdcard/oreoupdate-images/fastboot.img of=/dev/block/mmcblk0p5
As I have said, this might be bad advise , I have not done fastboot.img flashing before. But on other devices it is same as lk.img or uboot.img, There is danger in flashing it incorrectly. That is why my suggestion was to flash no-check-recovery and do manael update with "echo -update_package" commands.
Along with the statement that fastboot.img is similar to lk.img or uboot.img on other phones, Your fastboot cannot be gone. because phone boots.
but do let us know how it goes.
I agree it would be better to flash recovery if possible. I assume I need the NoCheck-Recovery image from this thread? https://forum.xda-developers.com/honor-7x/how-to/manual-update-to-oreo-beta-emui-8-bnd-t3767044
And what partition do I have to flash it to? I'm guessing either /dev/block/mmcblk0p28 (erecovery ramdisk) or /dev/block/mmcblk0p32 (recovery ramdisk)? I'm not sure what the difference is between erecovery and normal recovery.
(didn't flash fastboot yet, wanted to see if recovery was doable).

To recovery_ramdisk. 32
What about check md5 of fastboot partition, that will be helpful to know if it did get wiped out.?
Hmm seems like I'm not allowed to use dd after all:
HWBND-H:/ $ dd if=/storage/7C96-7E17/BND-RECOVERY-NoCheck.img of=/dev/block/mmcblk0p32
dd: /dev/block/mmcblk0p32: Permission denied
And here I was thinking I was close to solving it...
Also can't run md5sum on the fastboot partition, since that needs root as well.
