I just got my TF 700 and rooted an unlocked it, and all was ok, but then installed an app from the app store and now I only get "booting recovery kernel image" I was able to boot to APX mode install the driver and use Universal root toolkit for the TF and install the firmware from ASUS website but I think the boot image file is the problem. The transformer.bct is not for the TF700. Thanks in advace for any help.

No I cannot boot into recovery only APX mode and use nvflash. I am able to flash files. I have flashed the factory firmware from Asus. I think it is the boot image that is still bad. I used the recovery tool BRK_RootKit_v8.0_final to flash the image file but it tries to flash the original TF transformer.bct boot file. I think If I had the correct transformer.bct for the TF700 it would work.

AFAIK the nvflash method doesn't work for TF700 and is possible that you really bricked your device... The only solutionn i can see is to flash a recovery in fastboot mod and flash the Asus stock from there,but if you can't even boot in fastboot then i don't see any other way to recover the device.

I was hoping someone would be willing to make a backup of their file using nvflash. I think the zip should help.

Sorry mate,but according to this --> http://androidroot.mobi/2012/07/15/nvflash-for-tegra3-transformer-prime/ <-- i don't think you will be able to use nvflash for recovery and it clearly states that you need to get fastboot working in order to use that method. (to get in fastboot mode press Volume down + Power and release the buttons when the message about having 5 second to press Volume Up shows...if this work you will get to a menu with the "USB icon" wich means boot in fastboot mode).
P.S : Can you tell us why you had to mess with nvflash?That is the most advanced way to recover/backup the Transformer 101/201 series and you have really high chances to brick your device for good.
EDIT: I don't think someone here will be able to make a backup for you with nvflash...it will only lead to more bricks.
EDIT 2: Can you please tell us the name of the app that bricked your device so we can avoid other people bricking their device?
The app was transformer reboot recovery I think.
I only used nvflash because it was the only option left as the tab wouldn't work with adb or fastboot.
I guess I'll keep it as a paper weight.

Yes,i also used that app with no issue,but one of the developers behind TWRP advised to not use it at all,because if for some reason your recovery gets corrupted (that app send a custom command to boot into recovery) the device will boot loop trying to get in recovery and without nvflash we don't have many options to recover from that.
"
KEEP AWAY from that app for the moment,just stick with the old good " Volume Down + Power and then Volume UP " method to get into recovery.
Same issues here as well
I had rooted the TF700 ( as i wanted to download a market fix for my region, as i wasnt able to download GTA III) and had installed the eris market fix app :sillymy stupidity) it changed certain values to the original market application. After a reset/ reboot i was stuck at the powered by Nvidia Screen. I tried colding booting/ wiping etc non would work. I tried reinstalling the boot/system files through fastboot still no luck. what i cant understand is the fastboot setup seems to work when i id the Device it shows:
"? Fastboot"
i can reboot, push the system/ boot and recovery files, but cant boot into recovery mode. i have even pushed the twrp 2.2 file through fastboot. My only bet would be to boot into recovery so that i could mount and push custom roms.
I have even tried flashing the rom update through the following command "Fastboot flash update filename" however i get the archive cannot find android-info.txt error .
Is there anyway i could boot into recovery. (previously i could boot into recovery, but when i formatted/ erased the system and boot files i only get 2 options 1. Wipe Data & Cache & 2. Fastboot (USB). I tried holding the vol down button and the power button but that just puts me into blank screen mode and the APX driver pops up on the device manager.
I had to uninstall all my current drivers supporting asus and manually select the asus fastboot interface to get the fastboot working.
Any ideas would be helpful.

1The first step is to get your recovery back and working...here's a how-to:
1) Download the recovery from here
2) Follow the instruction on how to flash the recovery in fastboot mode
If the flash went good and you can get in recovery mode follow this steps:
1)Download the 9.4.5.26 firmware from Asus site (the SKU for your region)
2)Extract the .zip file somewere on your desktop (the result will be another .zip file,use it for step 3)
3)Put the extracted zip to a MicroSD card
4)Insert the MicroSD card in your tablet and boot into recovery
5)Install the zip from recovery and restard when done
If all goes well your tablet will be again up and running
Ray of Teamwin
:good::good::good:Thanks a million, seeing the team win screen relieved me. The only problem is i cant boot into recovery (teamwin screen is visible)through the wipe data mode, wherein everything is wiped and it reboots automatically. I cant seem to force the table into recovery without this is there any fastboot command which i can use to force the tablet into recovery.
Need Stock Boot, Recovery, System img
Still no luck with the recovery mode. Every time i wipe the device it automatically reboots. I was wondering if i could get hold of stock recovery, boot and system .img files so that i can push them or flash them through fastboot.
i tried using the blob pack and unpack but i cant seem to get around the blob header thing.
Anyone to spare me stock .img files
End of Infinity
Okay my frustration has led me to "fastboot erase bootloader" and now i am permanently stuck in APX mode.
However as nvflash is not avaliable for tf700t i guess i wont be using this for quiet sometime. Unless nvflash is made available

There's a thread (I can't find it again) that talks about this "Reboot into Recovery" app and how it might be bricking TF700T's. This guy wrote in, because he could not get to the recovery menu at all any more and could not do the "PWR+VOL-DOWN" combo. Nothing would happen. Maybe this was the thread, I don't know.
An XDA Mod in another thread said the app *might* be bricking them, but was waiting for confirmation before posting that it does.
I wish to confirm that IT DOES BRICK TF700T's! IT DOES!!!
And there is NOT A DAMN THING you can do! Your PC will not even recognize that the device is connected! You cannot get to the little icons to pick USB Mode, or whatever it's called.
This is the free app, not the other pay one in the Market. I don't know about that one, but this one is called, "Reboot into Recovery" and if you can somehow find that thread if I don't and just copy my post there, I would really appreciate it! I just want to warn people, ya know?
Also, using ANY of the "ROM Managers", whether it's CWM's, or GooMgr's, will take away all ability to get to a recovery menu at boot, at all! The device will still work and everything and boot to your Home Screen and everything. It won't be bricked like the app listed above does to it, but it will take away your recovery menu altogether and the PWR+VOLDOWN thing won't work any more either.
You can Unlock the TF700T, you can Root it. But you cannot use ANY ROM Mgr and you cannot use that Reboot into Recovery app.
But the app I listed above WILL BRICK YOUR DEVICE BEYOND ANY RECOVERY METHOD!
Please pass this on, I am confirming the experience. It doesn't matter if others say it worked for them. It is bricking them at random and even one of the guys who reviewed the app (diff guy than the one who posted here) said it bricked his. It is happening! It is not the user messing up! I did do it right!
Thanks!
I'm not sure if you are talking about the app named "Transformer Reboot to Recovery", but that particular app works fine on the TF700 - I use it all of the time.
The only time that it *can* cause problems is if your recovery is already corrupt or there is some other issue, in which case it can cause a bootloop.
But, if there are no issues, it works fine... There is a risk involved, like I said, if there are pre-existing problems with your device, but if you know that everything is working fine on your device, the app mentioned above works fine.

No offense, but I think a huge problem in forums, is that people don't read carefully.
1) I think you are referring to the paid app. Read what I said about that.
2) You're saying what you're saying, in a thread started by a guy who had a running device and who didn't after using the app.
3) I said that it bricks them AT RANDOM.
4) Another problem with forums, is that whenever someone has a problem, A LOT of users want to post responses that ignore the users' experience and they want to act like the problem doesn't "really" exist. If multiple people are posting the same problem, then IT DOES EXIST. It just doesn't exist for YOU! But something working for you, does not mean it works for everybody and it does not mean there is a problem with their device, nor that they did something wrong.
5) And yet another problem with forums, is that when someone like me points things like this out, many users will respond by jumping on me, instead of those who try to make the guy feel like he's hallucinating and who, instead of trying to help him out, or just keep their mouths shut if they have nothing helpful to offer, think the right thing to do is to argue with the person having the problem.
These forums are for help and information. If someone has neither to offer the person, or at least warn others, then why are they responding at all? And why would anyone defend someone doing that?! It's ridiculous! But that's what typically happens, especially in XDA doe some reason (lots of snobs here, who like to prove they are, by doing as I just described).
The bottom line is, you do not run the app I talked about and even if you did, that does not take away from the experience that some have had and the best thing, is to avoid the app, because there's a risk involved and there is no recovery from it. I decided to warn people. You decided to tell us that we're hallucinating and that people should use the app. You did not carefully read what I wrote, or you would have checked the Market to see what the name of the app that does not have a pay version is. The one I am talking about does not.
I will tell you this. I am posting this from my laptop, because I had to return my Tablet and have a replacement shipped and now I have to spend a few days getting it all set up again the way I had it.
Avoid the ROM Mgr apps on the TF700T. And avoid the free app called "Reboot into Recovery". A user told me about it for my device, who had seen it used successfully. However, if you look at the reviews in the Market, you'll see that one of them says it bricked his *WORKING* *FINE* tablet and this thread right here has told you about two more. So just believe it and don't criticize, huh?
Okay Mods, feel free to jump on me again, just like last time.
I agree with many of your points, Zeuszoos, and thanks for pointing that out, but I believe there are many senior members at XDA willing to help if they have knowledge/abilities to do so, that's been my experience so far and hopefully it can be yours too. Of course, a little SEARCH won't hurt before posting one's problem, as you reasonably mentioned yourself
"reboot to recovery" has been in my apps STICKY thread in the sections "apps to avoid" (RED) for quite some time now after first reports of bricking users' devices started popping up and I believe it has helped some users who did a little reading before clicking...
I'm still somewhat new to all this but after buying my tf700 last December I've been trying out a few things, unlocked/rooted and I have been happily using TWRP and various versions of Cromi X for months without any problem. Suddenly one day it didn't want to boot the ROM anymore and I have no idea the cuase (didn't just flash some kernel or drop the tablet, etc). I have TWRP 2.5.0.0 and CROMI-X 5.0.2.
I've dug through the forums and there doesn't seem to be anyone I can find who's having exactly the same problems. There was no special data I particuarlly needed on the tablet and I have backups on saved elsewhere so I am totally happy to wipe everything and start from scratch. I just want my tablet back. I'm just looking for the easist way to fix this (and I hope there is a way!) so any help is greatly appreciated.
Info is as follows:
Cromi x won't load stuck on ASUS logo. Same goes for cold booting
When I boot into recovery it says "Key driver not found.. Booting OS" at the top left
[when I enter TWRP it asks for password and says it can't mount E as below
when i "cancel" the password request i am taken to the usual home screen but installing from internal storage shows no files and a size of "0"
strangely I can get into the Micro SD card and load CROMI X from there which all goes through normally but at the finish when I'm going to reboot it says "No OS Installed!" and after restarting i'm back to same problem
I'm not getting the Fastboot USB logo I think I'm supposed to get in recovery when it is plugged it into my PC and ADB sideload in TWRP also not working (not so experienced with these though)
When I try to wipe data in TWRP I get "Failed" the message about being unable to mount E below
E: Unable to find partition size for '/misc'
E: Unable to find partition size for '/staging'
E: Unable to find partition size for '/data'

Looks like some issue with the internal eMMC. Reboot your tablet into TWRP, connect it to your PC and run on the PC:
Code:
adb shell dmesg > dmesg.txt
adb shell ls -l /dev/block/mmc* > mmc.txt
Post the 2 resulting files.
can't seem to connect through PC

Thanks very much for this. The problem I am having is I can't past the "error: device not found" message I get in the CMD on my (windows 7) PC. (yes I am opening the command line window on my android ADB folder). In fact the tablet doesn't appear in the Device Manager either. I'll admit I'm not so experienced working on the tablet through the PC (though I'm guessing I'm about to learn a lot), but I think the fact I get "Failed" when trying to ADB sideload in TWRP and nothing in the Device Manager is a big part of my problem though I'm stumped how to fix it.
Any ideas?

You may not have the correct drivers, but even then it should at least appear as unknown device.
I don't know which drivers you need for Windows (it's easier under Linux) but maybe someone else can help you here. I remember sbdags once posted which drivers worked for him, maybe you find it using the search function.
Try these drivers:

Thanks both for this, but the problem that I'm facing is I can't seem to get my PC to recognize the existence of the tablet (connected via USB with TWRP running) even as an unknown device. Because of this I'm not sure how to get the drivers loaded. Also have loaded Android SDK Build-Tools and Google USB Driver through the Android SDK Manager. That doesn't seem to solve it either.
Not surprisingly when I run fastboot from a cmd line window and look for adb devices the list is blank.
Not sure what else to do. Would be willing to create a second Ubuntu boot on my machine if using linux would help me get this fixed. Just at a loss about what to do.
Any further insights are welcome!!!

Is the tablet connected directly to the PC? No dock, no USB hub?
To check if your USB cable works, you can boot your tablet into APX mode (hold volume-up while turning on). The screen will stay black but the backlight should be on. You can only do something useful in this mode if you have previously created your blob file for wheelie/nvflash, but at least your PC should recognize the Tegra APX device (vendor 0x0955, device 0x7030).
If that also doesn't work, boot any live Linux distribution and run "lsusb". If that also shows no trace of the tablet (vendor ID should be 0b05 for normal operation or recovery, or 0955 for APX mode), then either your cable or your tablet's USB connection is broken.
Am I bricked?

Well you gave some great advice...I hadn't thought that the cable (which charges the tablet perfectly) could be the issue. I borrowed a cable from a friend who has the same machine and voila, recognized and could get into fastboot.
...and then with that problem solved, things got really bad.
I attempted to reflash TWRP on the tablet by pushing via fastboot as described on TeamWin's website. All was going perfectly until the tablet froze partway through the flash. Now when i power on, whether or not I hold vol down, I get a brief .5 seconds of the "Asus Inspiring innovation..." logo with a blue bar that goes up to about 75%, with "The device is unlocked" in the corner. After this brief 1/2 second it goes directly into APX -- black screen (though possibly back-lit) but, with the working Asus cable, Windows 7 recognizes the tablet as "Unknown Device"
I fear the device is now bricked as all the forums I've read seem to imply this. No, I didn't really know about creating a blob file for wheelie/nvflash before so don't have one (sure have read plenty about it now).
So...is this the end? Can I create a working blob file from my friend's device (I'm guessing not or it would have been thought of before)? or any other solution?
Or if not I've heard you can replace the motherboard though this is really unknown territory for me...I'm a bit curious so would be up for having a go but don't want to sink money into a helpless situation. Plus I don't know why any of this has happened in the first place so i fear there may be other parts that are not working properly.
Any useful insights on how to solve this problem I've created for myself would be greatly appreciated.
Sounds like it is bricked if you can't get into the bootloader.
What was the exact command you used to 'push' TWRP and which file did you use?

If you cannot get into the bootloader and APX mode is your only access .... without nvFlash - sorry, it's a brick :crying:
The blobs for nvFlash are device specific, so somebody elses would not help you.
Your only option is to sell it for parts or have the main board replaced.
I don't have experience with that (thank God), but there are tear-down videos and instructions on iFixit.com. Maybe that'll help you decide if it would be something you can do yourself.
Otherwise sending it to Asus and have them fix it would be your only option. It is expensive....
My condolences....

TF300T help
I've worked on this now for about 12 hours. I cannot figure it out. I run into the same roadblocks. I know this is an old thread, hopefully by now there's a solution for this kind of issue.
Can this be fixed in Odin or platform tools or something?
I've got TF300T where I believe I bungled the process by format/wiping from bootloader menu instead of TWRP. It's technically not bricked at all. But it's screwed up in the following ways (I was trying to get it to be a Clean Rom tablet, and there were so many sets of instructions, had them all open, and was trying to be careful about this, I've rooted and ROMed so many times and this is the first time I haven't been able to solve the issue in a reasonable amount of time)
-TWRP 2.5.0.0 asks for password, no pw ever set anywhere, tried all possibles that could feasibly be, but nothing works. This TWRP issue causes all cards to be invisible, it wiped by external SD, shows internal SD as having nothing in it but this is false as the OS boots ok (see below).
-cold boot or reboot leads to going straight into TWRP 2.5.0.0
-issuing command 'adb reboot bootloader' while in TWRP does take me into (bootloader?) 3 iconed menu, this menu is the only way I can boot the tablet into the normal Android system
-cannot factory restore the tablet from normal Android as it goes straight into TWRP following this action
-in the bootloader 3 iconed screen it is not seen by issuing that 'devices' command,
-thus cannot do 'fastboot -i 0x0b05 flash staging blob', TWRP disallows this also as the damn thing is locked down by a non-existent password.
I issued your commands:
DMESG.TXT (output too long to post here, exceeds xda allowable) &
MMC.TXT
brw------- 1 root root 179, 0 Jul 12 00:32 /dev/block/mmcblk0
brw------- 1 root root 179, 1 Jul 12 00:32 /dev/block/mmcblk0p1
Without a working fastboot connection you are one or two steps away from a hard brick. Proceed with caution!

Odin is for Samsung devices only, the platform tools give you adb and fastboot, see below

Usually the reason if TWRP is asking for a password is a corrupted data partition. The recovery cannot read /data, so it assumes that it's encrypted and it asks for the password. Surprising is that you can boot into Android if your data partition is corrupted!!
-cold boot or reboot leads to going straight into TWRP 2.5.0.0

That's what stumps me... Most of the time, if you use the "Wipe Data" option in the bootloader or do a factory reset from within the stock rom with TWRP installed, you end up in a forced reboot to recovery loop - no boot to rom, no boot into the bootloader. So you are saying a normal boot goes straight into TWRP, but you can adb reboot into the bootloader and from there, by selecting the Android icon, boot into the rom??

That's totally normal because the factory reset command calls the recovery to perform a wipe of data. Since you don't have the stock recovery it calls TWRP - but TWRP cannot resolve the command. Read this for background, but you probably don't need bootit.ko since you can boot into the bootloader anyway.. http://www.transformerforums.com/fo...my-transformer-tf700-boots-only-recovery.html
in the bootloader 3 iconed screen it is not seen by issuing that 'devices' command,
-thus cannot do 'fastboot -i 0x0b05 flash staging blob', TWRP disallows this also as the damn thing is locked down by a non-existent password.

This is the part that worries me. Without a fastboot connection you could be dead in the water pretty quickly. And that's the problem you should tackle first.
How did you get TWRP installed on the tablet? Not in fastboot? Most often fastboot not working is a PC driver problem. Read this to get fastboot working:
http://forum.xda-developers.com/tra...inners-guide-unlock-custom-rom-tf300-t3061648
There's also one very important information missing from your post: What bootloader are you on? your bootloader and recovery have to match and the rom you flash has to match both.
You COULD try to just format data in TWRP which should take care of the "missing password" problem and then flash the rom you want to run, but you better make sure the bootloader supports the rom!
And again - if that goes wrong and you don't have fastboot working, you could end up with a paperweight. Be careful!
Thanks for taking the time to answer. Understanding more of this is helpful (doesn't drive me as mad when I know that I don't need to keep trying passwords in TWRP). I'd like to be in a position where I knew knew all this stuff & could be helping others instead.
I thought the reason for all the lock ups was my wiping data from the 3 iconed menu rather than from twrp (the latter was supposed to do)

Yes. That would be the safest way to go, but you need fastboot for it. I thought you don't get the device ID returned when issuing 'fastboot devices' while in the bootloader??
As long as you can boot into the BL you don't need bootit.ko so follow that guide from the "fastboot devices" input
Correct, I do not have a fastboot ID.

That's what i mean: Probably a driver problem. Open Device Manager on the PC. then connect/disconnect the tablet while in the bootloader. Check if anything changes, check for yellow triangle next to the driver if it shows as Fastboot interface.
You can also try this in adb shell in recovery since you do have that working. This will also format your data partition:

The issue was resolved with the help of Joshua Lynch. He saw my post and PMed me. For those that are losing hope like I was, if you're coming back to this old tablet, all is not lost. I will post how this resolved as soon as I have time. Thanks for the answers. Bounty has been claimed.
the issue was a driver. the computer would only have one driver installed at a time and installing fastboot driver again fixed the not seen issue. I had installed another driver (as part of this process, and it eliminated the presence of fastboot driver), and was racking my brains because I didn't think to reinstall the original fastboot driver.
I had help from Joshua Lynch a couple months back on this. It turns out that the reason the tablet wasn't seen was indeed a driver issue. What had confused it with me is that I did physically install both drivers fastboot & adb. However, my system only allowed one to be active at a time. So when I was trying to, if I'm remembering this correctly, fastboot into the tablet to console, it wasn't seen because adb was the active driver. All that needed to be done was remove adb & put in fastboot.
Just to let you all know, I did a full one & zero wipe of the tablet & installed Zombi-Pop rom with Joshua's help. The tablet was still slower than hell. Slower than any device I've ever used. I'm talking 5 to 15 second delay time from when touching something & getting a response. I found that disabling everything google (except play store & play services) helped a great deal.
But the tablet has never returned to its former speed prior to the asus update. Tinfoil hat: I have this feeling that they sent out an update that permanently screwed up the hardware on purpose.

Question: do you know if the original stock software that the tablet came with (before the update) can be installed? Is there a full set of instruction on this (and the stock rom)? I've got a ton of files (some roms, some files from asus website) downloaded for this tablet. I've taken a break from this thing, returning to it now... Ready to take another crack at it.
If someone wants to make some money and help me out with this, I'll pay them a total of 50 if all goes well. First 20 for their service to get the thing back on stock, original out of box software and updates disabled, another 30 when I've seen after a few days, that indeed it was done right and fast like it originally was.
Reason for this is that I already gave someone 50 for their help with this and the outcome wasn't acceptable. I've invested a ton of time in this and the $$ put in so far exceeds the value of the tablet.
On Tuesday, my phone started restarting periodically without any input from me, so I decided to look up a solution on the web. There was one recommendation for me to boot into recovery mode and clear my cache, but in doing so I think I wiped out the contents of my SD Card.
I am using TWRP as my means of recovery. It has been on my phone for months now, because I used to dabble in changing my device's OS. The version number I'm using is
v2.7.1.1
On my bootloader (HBOOT), some more potentially necessary info:
K2_CL
HBOOT-2.21.0000
Right now, I am able to both boot into the bootloader and recovery, but when I normally power up my device, it gets stuck on the HTC animation. In TWRP, it indicates that there is "No OS installed" whenever I get the option to reboot my device.
I am able to push zip files on my device with adb, but lately my phone has also had trouble utilizing its USB connection. This might be merely a problem with my computer, because my USB drives haven't been working either. So, I can only use adb to push them onto my SD Card. For now, at least...
Here are the sources of the zip files I tried to use: http://forum.xda-developers.com/showthread.php?t=2562236
http://forum.xda-developers.com/showthread.php?t=2734434
When I go into TWRP to install a zip, it takes literally less than two seconds to report a success. I know that isn't supposed to happen, because it typically took more than a few minutes before, and because it's supposed to report an error. When I look into my reboot options, there still isn't an OS installed, and my phone still doesn't work properly. However, it lately also reports that it can't mount /data and /cache. This happens every time I try to install a .zip.
For now, I'm looking for answers to these 2 questions:
1. Is it possible to even restore my phone to working order? I've bricked my phone once before, but at the time I was able to rely on backups and the fact that TWRP didn't lie about its installations.
2. Where can I acquire Stock ROMs for Boost Mobile? I'm not sure if I've been using the proper sources for my .zip files. My HTC One SV was fully updated before it bricked, just so you guys now.
I have an Asus tf700t that i rooted a long time ago and was running Cromi-x 5.something. I also have TWRP recovery installed.
I can't even remember the details now but at one point about 12 months ago, i when to do a wipe & flash (which i did many times and I felt very confident doing with TWRP) and something went wrong.
All my tablet does now is turn on and flash at the TeamWin screen, that's it. I've allowed for the battery to drain, I've attempted holding the volume key in to boot into recovery, I've removed the SD card...nothing seems to get me un stuck.
I attached my tablet to my pc (which now is windows 8.1 x64) and all I get is an Unknown Transformer device. I have attempted to download and install the google SDK kit along with the original items i used to root my device, none of them seem to "click in".
Am I looking at a dead unit here?
cheers,
Dave
Did you use Wipe Data from the bootloader menu?
If yes, you may be in a forced reboot to recovery loop.
First thing to try is to connect the tablet to power and leave it in TWRP. If you're lucky it'll sort it out and eventually execute the wipe data command. I would leave it for 8 hours or so....
Can you get into the bootloader = fastboot mode?
When in TWRP do you get it recognized with
Code:
adb devices
?
If I'd prefer not to purchase a new phone, is there much risk a rootkit is installed? Or, is this certainly random device corruption that doesn't seem to be harming anything?
Is there anything I can do to fix the problem? (Yes, I could turn dm-verity off through adb, but that hides the error without fixing it.)
TL;DR
I have an Asus Zenfone V Verizon edition, which is the V520KL A006.
When I was using my phone a few days ago, it suddenly rebooted and since then shows:
Your device is corrupt. It can't be
trusted and may not work properly.

After a few days, I finally tried the power button, and it boots up just fine, and seems perfectly stable. I performed complete backups, and for what it's worth, I ran a bunch of droid virus/malware/rootkit scanners, and they found nothing. (Obviously, a good rootkit will hide itself.)
I eventually did a factory reset. This went well, but the red error message remains. So, I believe the corruption must be in a partition that a reset doesn't replace.
MORE DETAILS
I've never unlocked, rooted, or installed a custom ROM onto this phone. The only "beyond typical user" thing I'd previously done is to install adb sourced directly from Google, to be able to run Genymobile's scrcpy, which is an extremely fast open source program that allows me to remotely control my phone from my linux PC, via USB or wireless. I've been using this for many months without any issues.
This appears to mean dm-verity is detecting corruption, and is the "red" version of it which many have described as the death of their device. I believe this means the phone is able to verify the signature on the bootloader and it's able to verify the signature on the kernel, but that the kernel is finding an invalid block(s) on one of the many partitions being read right at turning on (detected because the hash for the block is not as expected.) When this happens, an I/O error is given indicating the block cannot be read.
I have been quite concerned if this might indicate a rootkit had been installed. I haven't done anything that I would suspect could let one in. After spending a lot of time learning about adb, fastboot, TWRP, and having the ultimate goal of discovering which partition has an unexpected hash, determining if this meant a rootkit or file corruption, and fixing the error, I've hit many brick walls.
For a day or two, I avoided seeing if the power button would allow it to boot, because if there was a rootkit, I didn't want it to run. I was disappointed to learn that through fastboot (specifically, I mean the fastboot PC program that connects to the droid when in fastboot mode), there is no way to do something like a full bitwise image of the internal storage, and analyze the situation in linux. Or, any type of backup whatsoever. I was frustrated to learn from another XDA thread about a lot of problems others have had rooting and/or installing TWRP on this device. I was frustrated to see there is no prebuilt version of TWRP for my device. (There is an image for the Asus ZenFone 5z 2018 ZS620KL which is very different than my Zenfone V520KL V.)
I realized with my particular device, I think, the only way I was going to take any next step required hitting the power button. (As I mentioned way above, that's when I found it appears to work fine, and I eventually did a factory reset.)
I attempted using the TWRP recovery.img posted by game #1 in that XDA thread about my device, but like he encountered, fastboot boot recovery.img doesn't work, and just reboots instead.
Without being able to extract the original recovery.img, I'm not sure that I'm willing to install his and see if it works for me. I was frustrated to find there appears to be no way to extract the original recovery.img without first having root access. All non-root methods I later found to do this didn't work. Notably, su can't run anymore through adb, and adb root can't run with a user build.
I've looked a bit at custom compiling TWRP myself, but haven't done that yet. In part, because if my version doesn't work through fastboot boot recovery.img, I'd have the same concern about overwriting the original one before getting some feedback here. Also in part, because I haven't looked enough to find how someone goes about making a BoardConfig.mk and the device tree from scratch.
Hey. I tried installing TRWP on my device, Asus Zenfone 5Z (ZS620KL) but I also got the same message. "This phone is corrupted and cannot be trusted." It also said it won't boot. Now I am stuck in Fastboot mode.
I tried installing a stock rom. Downloaded the firmware. i even downloaded python so I can extract the payload.bin file. Followed the steps but still to no avail.
Is there anyone who could help me?
If you could attach the files that I would be needing, that would be a great help.
Thanks.
