[Q][help] bricked badly after failed encrypt - fastboot and ODIN can't write to flash

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 !

Honor 7x with Lineage and TWRP, stuck in limbo

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?

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.

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

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.

XL Bricked

Hi people,
I unlocked, rooted, and flashed Liquid on my XL tonight. Everything seemed to be going fine when I rebooted again and got a bootloop. TWRP is not loading, what I am getting is the Android on it's back menu and here's where I'm lost. I'm getting the error in the screenshots when I try to sideload the factory image from ADB. My cords are good, drivers are updated, and I have ADB and Fastboot set to Large Address Aware. I don't want to admit that I have a paperweight now. Any ideas? Thanks in Advance

Can you reboot to download mode (fastboot)? Hold the power button and vol down buttons together.
If you can get into the bootloader, use fastboot to flash the factory image instead of using adb. Or try issuing 'adb reboot-bootloader' command to reboot to bootloader

Both volume buttons? I've only done the power and down volume. I will try both of these when I get home tonight, or when I wake up. I stayed up until 6am working on this and did not get much sleep. I'm also going to uninstall and reinstall the Pixel driver. I don't remember off the top of my head if I installed it before or after I upgraded my laptop to Windows 10.

Sorry for being unclear. To get into the bootloader (where you can use the fastboot command to re-flash the factory image), you hold the Power Button and Volume Down buttons together (not volume up button). This is what your screen should look like if you successfully get to the bootloader: https://www.xda-developers.com/files/2016/10/CvqcEDHUsAA_EY4.jpg
If you see that screen, you're sitting good. Download the latest factory image (https://developers.google.com/android/images#marlin) and run the flash-all.bat (for windows) script to reflash your phone. You will have to have fastboot drivers installed on your computer for that to work.
If your device is recognized by adb (if you type 'adb devices' and it shows your device as the output) but you are having trouble getting to the bootloader, you can type in 'adb reboot-bootloader' to reboot your device into fastboot mode where you can flash the factory image. Hopefully that helps push you in the right direction. Your phone isn't bricked/lost forever if adb or fastboot recognizes your device and you can save it!

That's where that first screenshot came from. I will try the reboot bootloader tonight. They sort of recognize my phone, but I can't get them to flash anything. This isn't my first rodeo with borked phones, but I don't think I've had this much trouble since I placed the wrong boot animation on my Droid 4 many years ago.

:victory: :highfive: It's flashing right now. You don't know how much I appreciate it.

Hi, thought I would jump in on this thread. I have the same issue, and I can get to the fastboot screen and device is recognised by adb with "fastboot devices". When I try to flash-all I get the message that the device must be unlocked. Any idea why mine in different? I just have stock recovery, maybe that is it. The device also will not boot into recovery, it just bootloops

Before you can flash the factory image, you have to unlock the bootloader by issuing this command first: 'fastboot flashing unlock'

X2 Pro: "Your device is corrupt. It can’t be trusted and may not work properly."

X2 Pro: "Your device is corrupt. It can’t be trusted and may not work properly."
Hi everybody,
my Aquaris X2 Pro worked fine with rooted BQ 1.7.3 firmware (Android 8.1 based) - Magisk was installed and worked fine and also the xposed framework.
Today the device was normally working as it suddenly just reboots
After that the usual "unlocked bootloader" screen appears but then it only shows a screen with the message "Your device is corrupt. It can’t be trusted and may not work properly."
I can select "continue" - but that only leads back to the "unlocked bootloader" warning screen --> a boot loop :crying:
Does anybody know how I can bring back my device back to work - without losing all my settings and stuff?
And any idea what happened (so that I can prevent it to do so in future)?

Hmm, I'm not 100% sure, but I think I saw that message / boot process once as I tried to root my X2 Pro.
I had done a
Code:
fastboot flashing unlock / unlock-critical
but no
Code:
fastboot oem unlock
(or the other way round? Definitely only done one of them - I was following instructions from a thread here)
and was trying to boot a magisk patched boot-img via
Code:
fastboot boot magisk_patched.img
So, it looked like the bootloader was "NOT fully" unlocked and it detected booting a "not correctly signed" bootloader.
Perhaps check your unlock status via
Code:
fastboot getvar all
But note - UNLOCKING again will wipe your data ... and can only be done if the setting in developer options is active (I fear that THAT may have changed on your device)
You could also try booting the second slot
Code:
fastboot getvar current-slot
and then
Code:
fastboot set_active a/b
(if current-slot gives a, boot b and vica versa).
Last idea: try flashing ONLY the stock boot.img. If you can do this, this should re-enable you to boot. You will loose root, but may be able to backup (most) of your settings via Helium

Thanks a lot for your help!
Inbetween I had to go the hard way and reflashed the newest BQ factory image v2.0.2 (based on Android 9) to both parts _a and _b - losing all my data...
after that I patched the boot.img for magisk and reflashed that to my _a boot partition (and still have the original boot.img in _b).
It did cost me a bit of my spare time - but it wasn't as hard as I expected...
I was able to restore a lot of my settings with Titanium backup....

That was exactly what I did - the first time I only did a "flashing unlock", no "unlock-critical" - so now I had to do it to flash the complete factory image, and therefore it wiped all my data again

I used the BQ batch script to flash it, but did not execute the erase commands.
But that did not help to keep my data as I needed to execute a "unlock-critical"...

You are most welcome
The erase commands are not the ones doing the factory-reset - if you want to keep your data during a "factory-flash" you need to comment/delete the lines which flash the userdata-partition.
But I do not know if you can flash the factory image without unlocked critical (=boot) flashing. I never tried this myself. Some phones allow flashing of correctly signed boot images even when critical is locked, others prevent ALL flashing then.
Of course, for "he who knows what he is doing" there is always the possibility to flash in EDL-mode (turn off, afterwards keep vol+, Vol- and Power pressed - will bring you to a special flash mode that allows flashing even when locked - but via a special serial interface etc. pp.). Google it - this would have helped you regarding "loose of userdata when doing unlock critical". But of course - you need to edit the file because in EDL mode, normally userdata is flashed, too.
Just something to keep in mind for the next time
Hmm, it worked for several months without problems - don't know why it suddenly complained about it.
That would be a great idea :good: which I could've tried - but I didn't...; maybe next time - although I hope the problem will never come back

I think that perhaps an update was installed (explanation for the reboot?!) that switched to the other boot-slot and did a more thorough check of the boot-chain. This was the reason to suggest trying the other boot-slot (which would then be the pre-update version, that may still boot - and even have root)

I hope that wasn't the reason, because I explicitly switched off all automatic updates. And I did not do a manual update!

I tried to switch to the other slot and boot it - but that didn't help either and led to the same problem...
What I didn't tried was to only flash the boot.img - will do this next time

Question 9 Pro crashed to lockscreen on loop, forced reboot and will no longer boot

hey, i have a completely stock 9 pro, i was texting someone and sending them pictures from the night but while i was doing that the phone suddenly crashed to the lock screen over and over again. so i just hard rebooted it since it was completely unresponsive and just crashing on the lock screen and now it will not even boot up it just shows the oneplus log and a field to put in a password and after entering the password its looking to format the phone and probably factory reset the whole device i was hoping that there would be some way to use adb to get my photos back since i didnt get a chance to save or send them and it would be a real bummer if they were gone. not enough to pay 1000s of dollar but enough that i would spend time playing with adb to recover them. im very familiar with commandline and adb but i dont know of a way to get in without unlocking the bootloader first.... any help would be very much appreciated.

Can you manage to boot into fastboot and try some things there?
Setup platform tools (let me know if you do not have it setup) and then boot into fastboot. Connect your device to your computer and try out the following commands :
fastboot getvar current-slot
If this outputs something like :
current-slot: b
Then run the following command :
fastboot --set-active=a
otherwise, run the following command :
fastboot --set-active=b
After this is done, reboot your device by running :
fastboot reboot

Like the original poster above. my completely stock OP9P (with all official updates installed) is stuck in a bool loop in which it displays the 1+ logo for a fraction of a sec, then reboots. I believe this was the result of the phone being unlocked in my pocket and something happening. When I pulled the phone out of my pocket, there was a message about a corruption in the OS on the screen.
I am able to get it to boot to fastboot by holding the Vol +&- buttons during the boot cycle, but I don't know how to recover the OS.
Can anyone help guide me or point me at a thread with tools that I can try?
Thanks, in advance.

I never set bios or lockscreen passwords, or encrypt data drives. You are the one most likely to be locked out, sometimes through no fault of your own. People will steal these devices regardless if they're locked or not; physical security is the only type of security that works.

When you enter the Bootloader (fastboot as you call it), and by navigating with the volume buttons, choose the "reboot to recovery" and confirm with the power button. This will reboot you to the recovery, and from there you can again use the Volume buttons to navigate and choose to wipe your data/phone.
This will format your internal storage, so your data is lost, but it will most likely help you with the issue you have. Another solution would be to use the MSM tools and "unbrick" the phone from EDL. Just by getting into recovery and formating your phone should do the trick, if not, MSM will fix it since it is the unbrick tool.

Thank you for the response. Sorry for the bad nomenclature. It's been a long time since I have used anything except stock. (Go all the way back to the custom ROMs on my Note 4)
I've tried that. Booting to recovery puts it right back into the boot loop.
It seems like there's a way to sideload the stock OS, but I can't find a cohesive, step-by-step guide that'll walk a N00B like me through.

There is no way to sideload it with a locked bootloader. Your only way out now is the MSM tool.

You can't do a factory reset from there?
It's rare but a SEU can corrupt any part of the flash memory. It causes no physical damage but the altered memory cells will need reset.

I think the best way to recover is MSM tool for youre specific model phone.
My phone power off by it self after watching a video on a received link with whatsapp.
Nothing workt beside MSM. I factory reset, downgrade rom. flash-reflash rom's.
MSM wipe all in youre phone.

Sorry for the slow reply, but I haven't had time to deal with the problem because of work. I'll be looking into this today.

Ho Lee Sheet! I finally got around to dedicating serious time to working on this.
I had to jack-around with it quite a bit to get Windows 11 to load the proper drivers so that the phone would be recognized, but: BOOM! BACK IN BUSINESS!
Thank you so much for the guidance.
