Hey guys! I'm writing, because I screwed up so much and need your help. Well, let's begin:
I wanted to install CM13 on my tablet. It was rooted, but I forgot that bootloader is locked.. Flashed TWRP through the app, rebooted and.. I've got big red warning: Can't load Invalid boot image !!!
This is how it is. The biggest problem is, I can't somehow flash anything, software, boot.img, new recovery, because everytime I got info in console: Cannot flash before unlock.
I've read that you need to download official Asus app to unlock bootloader, but I can't get an access to it right now, because I can't boot my Asus Any ideas what am I supposed to do?
Thanks in advance, cheers!

Hi guys!
I am kind of new to Android, but I bought a Lenovo A7600H, updated to 4.4.2 and rooted it.
By "mistake" I deleted at least one apk-file in the system folder. I wanted to update to the newest firmware, but due to the missing files I wasn't able to update. So I tried to flash it with the original factory image, which didn't work with SP flash tool, so I tried to flash with fastboot.
Apparently I applied the "system.img" to the recovery partition with the command "fastboot recovery system.img". Now, when I turn on the tab, it just says "SYSTEM image incorrect! Shutdown after 10,9,8,... seconds".
Is there anything I can do now or is my tab lost forever?
Thanks in advance for any help and sorry for the bad description.
Hi! I've managed to brick my device (d610ar) badly, i think
the device doesn't boot normally (message "Secure booting error! Cause: boot certification verify.", and i am stuck there), can't charge it with the wall charger, and the only thing that works is download mode; but flashing a kdz with LG FlashTool (the way i went back to stock a few times) says flashing and at 2% (or 3% sometimes) it says that doesn't find the device, that i have pull out the battery to reconnect my device again and when i do that it does the same thing on a loop, asking to do it again later..
the funny thing is that it appears on device manager on windows, on com port 11 for example, but the FlashTool doesn't recognize it..
so, i can't flash any kdz and doesn't boot.. i've read around here in xda to enter fastboot to fix it, but.. can this device enter fastboot? i couldn't do it, tried adb too and couldn't make the device visible..
i, before this happened, had multirom installed, rebooted to recovery and deleted secondary roms to install in primary rom cm12.1.. there started to happen strange things when rebooted normally to configure it..
after a while trying to boot found around here in xda too that i could enter twrp recovery via hardware keys to reinstall again, so got into it and installed a flashable zip to come back to stock KitKat directly, that have worked for me before..
after that rebooted and i can't do anything else than download mode..
i kinda figured that the problem must be that multirom injected the boot sector after installing the stock flashable zip, and when i did that restored the stock aboot and abootb (these, modified carefully, allowed us to unlock bootloader and flash recoveries, etc, etc.. ; by the way, many thanks to the devs that discovered it and made the guides!)..
now i have read the instructions for flash via fastboot the stock boot.img and so pass the security verification, but i can't enter it..
so, what do you think that could be the next step? or is it really hard bricked and i should forget about it? i'm really hoping to recover it but i don't know what else to do..
sorry for the bad english, not my primary language
thanks for reading and i am hoping to hear some suggestions!
He is not hard bricked you need to flash stock boot and reunlock bootloader if you have custom recovery still installed, but go first with the eazy way search xda about lg flash tool stuck at 2% there some guides to help you get kdz flashed
Thank you very much!

Thank you very much! You made me realize why wasn't working..
Because of you, i started to search threads related with the "flashtool stuck at 2%" and one of the things to look at was a txt file to see what was the problem.. there i found out that the lg FlashTool recognized my device as LGD618..
That's when i realized that i must've messed up when i flashed a lollipop flashable zip for the D618(a while ago), "converting" my cellphone on that model.. so when i connected on download mode and put the LGD610 kdz the comparison of cellphone model and binary model didn't match..
Solution was to flash LGD618 kdz, boot up normally, install towelroot, install supersu, edit a line on build.prop
from persist.multisim.config=dsds to persist.multisim.config=none
rebooted and that's it.. everything works perfectly now! i won't be doing stuff to it for a while
probably will stay stock like that, because now i will be using an OnePlus One in a few days and the G2 mini will be used by my mother, i think..
Thanks again! You saved my device for being bricked forever
i glad i could helped you :good:
I tried installing kitkat having installed lollipop and did not work, also I tried installing lollipop and nothing. Well I think this update lollipop are adding some kind of lock to disallow downgrade or upgrade by KDZ. I try other methods, unlocking bootloader, and install a aboot.img, bricked my phone. I recommend that you do not attempt to unlock the bootloader and install any system image that is not official, or may end up with a dead device.
Hi experts!
Is there an available factory image of the latest firmware for griffin xt1650-03 for download? I unlocked my boot loader and tried to flash custom firmware now I am stuck in boot loop. My phone was nougat and updated via OTA last week before I decided to unlock boot loader. I tried loading the latest image I got from firmware.center but I am getting Downgrade version and verification failed when flashing stock partition and not loader. Please help
Note: I did this my wifi became unusable after my last OTA (mac 02:00:00:00) and thought using custom firmware would help
And I did not make a back up
Get it in fastboot mode, flash TWRP and root it. That might work.
I am in exactly the same position as OP, although I have successfully installed TWRP and have open bootloader from which I can boot into TWRP no probs. I didnt do a backup (will never again make this error!!)
The problem arises when I try to flash (any) files over to device I get the "Downgrade version and verification failed" like OP when flashing stock Telus rom (telus phone) or any other rom/files.
Rebooting brings me back to the moto unlocked bootloader page (horrible!) and the only way out is to get key combo or fastboot into bootloader/recovery etc.
Tried flashing multiple images as whole or bit by bit, always get the same bad validation message. Finding it hard to believe this 700dollar phone is a brick after literally following MotoS own 'unlock your bootloader' instructions. Never had issues like this on OPO, S6, S7, LG etc.
PC shows android device connected, nothing in the two empty folders that appear. TWRP confirms I have no OS installed and throws me back to bootloader.Wondering if locking bootloader again will allow me to install 'stock' ROM or at least recovery? I have reached my android knowledge limit and am not sure where to go from here, any help much appreciated!
OK. This happened to me. The way that I solved it was by flashing the RETUS NPL86.25.15 and then flashing the OTA 25.17-3-3 through twrp. Although I think I could've saved the headache if the original instructions included flashing the OEM.bin but anyways. That's what I did. Hope it helps.
Thanks. I did try flashing the oem.bin but got partition name error.
Can you link to the files you mention I think it's a kernel and then an OTA image? Thanks again in advance.
What I mean is that when I first started flashing the RETUS rom the instructions skipped that part so I ended up flashing most of the file system without something so it would never boot but it wouldn't loop it'd just hang. So basically you flash everything and then include the OEM.bin after you do the system chunks
Hello!
Thanks for reading this thread, there's a lot that I'm about to say based on what has happened for the past 8 hours of troubleshooting.
I hope you'll be able to help me regarding my issue.
Everything was going well as I on my way to unlock my bootloader (done) and root my device.
After rooting via TWRP, I'm stuck on the white XPERIA logo screen.
Proceeded to wipe my phone, and thanks to my stupidity, loss of OS.
Downloaded an GLOBAL OS online, tried to flash into my device with FlashTool.
Error came to me as I needed flash script.
Search online, to no avail, I went to my final option
I saw a tutorial of creating a pre-rooted ROM : https://forum.xda-developers.com/crossdevice-dev/sony/tool-prfcreator-easily-create-pre-t2859904
I attached my OS I previously downloaded which i tried to flash with FlashTool, attached SuperSu into the application and a flashablezip (as instructed).
Flashed this pre-rooted ROM into my device using TWRP, rebooted.
New problem: Stuck at white Sony logo, couldn't enter TWRP.
Flashed in via cmd.exe a working boot.img & recovery.img.
TWRP now works, but I'm back to square one : stuck at the white XPERIA logo screen.
If you've read all of that, I thank you so much for doing so.
I hope that you'll be able to help me after these gruesome 8-hours of researching, trial & error session.
It's about time I requested help from professionals.
Thank you!
Edit : I can boot up my phone now, however that's achievable by removing SuperSu via TWRP.
This is no longer an urgent need for help, but it will be nice if I could get an idea why would I be stuck at the XPERIA logo screen when SuperSu is installed.

Hi, without any logcat it will be very hard to help you
Hello, everyone.
I'm not sure if this is the right forum.
My 1801P was trapped in a bootloop.
Then I tried to reset it with Power+VOL- -> Wipe.
Well, the stupid thing is now apparently the bootloader is gone.
Signature mismatch
Booting failed
Unrecoverable bootloader error (0x00000008).
Can someone help me?
Same Problem
Hello everybody,
I have two stock ASUS P1801 and one got stuck in this bootloader error. It happened once or twice and I was able to restart it until the last reboot.
I have still access to the recovery and I did a "wipe data" that did not solve the problem. Unfortunately, this was also the only solution proposed by the ASUS customer service.
I downloaded the original firmware on a SD card but I think it was not loaded on the P1801 because I don't know the naming convention for the zip file.
Do you think it is also possible to use fastboot to flash it even if the bootloader is not unlocked?
Thanks for your advices.
