[Q]Soft Brick boots to development warning screen

DISCLAIMER: I'm completely lost, so please break things down into bite-size steps or at least expect some follow-up questions on my part. I'm one of those desperate guys who is attempting to just have a working phone tomorrow. Any help will get as many presses of the thank button as I can possible give.
After several hours of plodding and poking and searching I've managed to do some possibly irreparable damage to my htc one v. Whenever I try to boot the phone it starts up with the htc developer red text "development use only" etc etc. I can access the bootloader and recovery thankfully, so I guess there's hope.
I think the source of my troubles is what's addressed by the essential reading at the top of this sub-forum, ie distinguishing between GSM and CDMA. I think (and this is an assumption here) that despite being in the USA on virgin, the fact that I can shove a sd-card in there means it's GSM (correct me if I'm wrong. please). EDIT: It seems that the phone only works with the CDMA version of TWRP, so I guess that might be an indicator.
Info: htc one v, virgin USA, using TWRP 2.3.3.0, attempted to flash Rom using various versions of Paranoid Android
What I've done thus far:
1. Unlocked bootloader
2. Flashed recovery
2.5. Created backup
3. rooted device (I downloaded rootchecker or somesuch app and was able to confirm that I had rooted my device)
4. Wiped cache and dalvik cache (I think that's what it's called).
5. Attempted to do a factory reset (failed).
6. Attempted to flash ROM (failed)
7. Restarted Device (got stuck on dev screen for the first time).
8. Tried recovering using backup created earlier (which just booted me into the dev screen of doom again).
9. Tried partitioning sd card in an attempt to perform a factory reset (wiped everything including backup).
10. Factory Reset failed with a message about not being able to mount /sd-ext.
11. Tried flashing rom again with different version of PA for shiggles (it worked! oh frabjous day!)
12. Rebooted phone only to get stuck on the dev screen again.

I've been at this for nigh on 7 hours and all I have to show for it is a phone I can't use. Help.

Let's try this in order: if you are with Virgin Mobile, it is a CDMA. GSM phones take a sim card, both versions accept an sd card for storage.
Everything looks good until:
#5 The failed warning is due to lack of a SD EXT partition on your sd card. If you didn't re-partition it, you will get that failed warning. No big deal as it is wiping everything else correctly.
#6 You also need to wipe system prior to flashing your new rom.
After flash your new rom, you will need to connect to your pc and boot into bootloader. Make sure it says "Fastboot USB" at the top your phone screen. You have to flash the boot.img for the specific rom you are trying to install. See the rom thread for the correct method.
Check your radio and Hboot version in bootloader. If you have the newer radio (xxx.xxx.928) and Hboot (1.57), you are limited on the roms that will actually work. Check the CDMA development thread for roms that specify OTA compatible.
Good luck. If you have any more questions, feel free to ask.

Which ROM you have flashed?
Did you install boot.IMG according to your ROM?
Sent from my HTC T320e

If you're restoring "stock" sense 4.0 ROM, you need to flash a kernel that will work with it. Try Titanium-KISS or Stock. The stock one should have been kernel should have been backed up, it's labeled boot.IMG in the backup folder. EDIT: Since you are CDMA, you need to flash this kernel in Fastboot to get it to boot: http://forum.xda-developers.com/showthread.php?t=2024758. Be sure you flashed the CDMA ParanoidAndroid as well, and not the GSM one.

followup
FIRST: Just thought of something that might be very important, I only had a version of android 4.0 installed on my phone. Will that make a difference when installing roms intended for later versions of android? If so, I feel like a huge knuckle-dragging fool.
Update: Was able to install and boot using PACman, but ran into a boot-loop.
But to follow up to your questions:

I'll admit I've had a hard time find a definitive version of PA or really any other Rom. I've tried going through their thread here and downloading one of the "stables" (http://goo.im/devs/gannon5197/paranoid/primoc/stables/). I've also used other unofficial versions of PA (http://forum.xda-developers.com/showthread.php?t=1799372). I'm currently downloading PACman to see if that will make any difference.

I did flash my boot.img using the method explained here:
Copy the kernel image (boot.img file you have extracted from zip file of ROM) to folder in which you have kept your fastboot files.
In the same folder, right click while holding shift button and select ‘Open command window here’.
A command window will appear on your screen. In command window type ‘fastboot flash boot boot.img’ and press enter.
On your screen you will get message ’OKAY/Finished’. You have successfully flashed kernel. Now you can disconnect your phone from computer.

I'd like to think I'd partitioned it properly, but I keep getting a "unable to mount sd-ext" or "unable to wipe sd-ext" message when I attempt a factory reset. I've tried formatting the the mini sd and set the file type to FAT32, but to no avail as the errors persist. I know you said not to be too concerned, but I keep failing the system wipe from your next suggestion because of that error.
#6 You also need to wipe system prior to flashing your new rom.
After flash your new rom, you will need to connect to your pc and boot into bootloader. Make sure it says "Fastboot USB" at the top your phone screen. You have to flash the boot.img for the specific rom you are trying to install. See the rom thread for the correct method.

Now how important is it that I flash the boot.img after I have flashed the rom? I've been doing it beforehand, but does doing it afterward make a difference?
Check your radio and Hboot version in bootloader. If you have the newer radio (xxx.xxx.928) and Hboot (1.57), you are limited on the roms that will actually work. Check the CDMA development thread for roms that specify OTA compatible.
Click to expand...

Those both match my radio and bootloader, what does that imply? I'm planning on flashing this rom: http://forum.xda-developers.com/showthread.php?t=1948034
Will that work?

No, it won't. You have the newer updated hboot and radio. That is the source of your boot loops. The only compatible roms at this time are MyOneV, ExtremeSemse, and RhythmicRom. You can also use Cyanprimo, but you'll have flash the boot.img from RhythmicRom.

Now I've downloaded RythmicRom and I'm still stuck in a boot loop. I'm sorry for being a bit thick, but could you link some roms that would be compatible or explain what I need to be looking for?
Version I downloaded: http://forum.xda-developers.com/showthread.php?t=2147407

You'll need to download the 1.2 update, then extract the boot.img from that. The boot.img in the Rom doesn't work with the new update.

So I've been reading up on the issue over here: http://forum.xda-developers.com/showthread.php?t=2018518&page=14
and while I don't claim to understand it all, I believe I get the gist of it.
I also've managed to get RythmicRom working thanks to riggerman. I guess I'll just play the waiting game until someone rolls out a fix or just replace my phone (though that's very much in the long-run).
Once again, thanks to everyone and hopefully this will be the last we see of this mess.

Glad you got it running, and glad I could help.

[root] [ZS570KL] Asus Zenfone 3 Deluxe fast rooting method. Despite TWRP

Not tested on nougat.
I use adb and fastboot , twrp, supersu.
Files We need:
TWRP: It's bogus, in my phone the screen flips upsidedown: Connect a mouse thru female usb or try to figure out how to tap in a rotated screen with a non rotated touch panel.
TWRP Download -> https://drive.google.com/file/d/0B0XMYw0cbs_cdm5FZW1DQXl4MFU/view
SuperSU file - > https://download.chainfire.eu/1021/SuperSU/SR3-SuperSU-v2.79-SR3-20170114223742.zip?retrieve_file=1
For ADB access thru MAC:
1.- First of all we have to get open USB debug mode to get adb acces to the phone by going to Settings -> About -> Software Information -> Tap 7 times over Build number.
2.- After we get Developer options available we have to put the phone on usb debugging by goig to "Settings-> Developer Options" Activate USB Debugging.
3.- Install android platform-tools on your PC/Linux/MAC , in my case had work on MAC and no devices acces thru ADB on PC :silly: .
platform-tools -> http://www.androidpolice.com/2017/0...ble-without-full-sdk-android-studio-download/
Here you have the 3 options to download ADB and FASTBOOT
4.- Connect your phone to the PC (USB) and copy SuperSu to the root of your phone, a place that its easy too acces, cause TWRP, for the moment flips the screen.
5.- Copy TWRP3.0.XXX.zip to the folder where you have platform-tools installed.
6.- Reboot your phone to bootloader and in Linux could work too:
./adb reboot bootloader [./ is placed cause I don't put platform-tools on the my PATH]
After the boot, then we have to boot on TWRP
./fastboot boot twrp-3.0xxxx.zip (you don't flash anything) If you want to flash TWRP, at your awn risk, ./fastboot flash recovery twrp-3.0xxxx.zip".
Well, now you have to see TRWP on your phone screen.
My recomendation is to play a little bit with the flipped screen if you don't have a female USB to plug a mouse.
7.- Trying to make a complete backup of the phone could be a good practice to move on TWRP with the flipped screen . Tap backup option and make a Backup. Always recomended!
8.- After Backup, you can go to INSTALL SuperSU.zip file. "Install -> look for your SuperSU.zip file "
9.- Go to Playstore and install supersu app.
Now you can test your root, after reboot for example tryin to install some APP that requires root. Fast move:
./adb shell
su root
It has to appear a screen to grant root access to the phone.
10. Done!
Well I think thats my second post at all, hope can help someone to root the phone.
I placed In Questions and Answers cause XDA says want to protect us from SPAM.
Feel free to correct me anything.

Links are corrected. Thanks!

You can also substitute Magisk instead of Supersu if you need to use any of the pay apps or have root sensitive apps...

Without the right Twrp, many benefits to rooting are missing such as removing stock rom applications. Seems without being able to boot to a recovery, even Titanium cannot remove apps because it needs to clean the dalvic.. Can't do it without a recovery

You should change your title !!
Tested on nougat.
The variant ZS550KL can be rooted with same method on latest firmware with nougat

Very nice guide, Thank you. Could you please provide updated links to both TWRP and SuperSU. I am currently using TWRP 3.1.1-0 and it functions properly after hanging for approximately 45 seconds on boot. This may be due to the fact my phone is encrypted. I initially rooted without installing TWRP (fastboot boot twrp.img) but have since flashed it. Both ways work well. The posted version of SuperSU did result in root but caused me to lose cell service! The phone could "see" the sim card but not use it. Updating to SuperSU 2.82 solved that issue. This was all done on my finally rooted ZenFone 3 Deluxe Special Edition (Z016D)!!!

I unfortunately figured something out the other day. Using TWRP 3.1.1-0 I am able to install zip files, complete wipes, make & restore backups. The issues only arise after you restore your nandroid image. Everything works except for two things.
1. The ability to hear audio during phone calls. The phone is actually able to place calls but you are unable to hear or record any phone audio. Oddly enough I was able to play music and use voice dictation. It was only in-call audio that seemed to be affected.
2. If you have a pin set when you create your nandroid image your pin will no longer work once restored. You will be locked out of your own phone!!
Fortunately both are fairly easily resolved and keep TWRP relatively useful, although a bit bothersome!
To resolve the pin issue it is necessary to use the TWRP file manager or ADB to delete 5 files (listed below) and regain entrance to your phone. Once deleted simply reboot the phone and reset your pin. If you remove your pin before creating a backup this issue is averted completely.
/data/system/gatekeeper.pattern.key
/data/system/gatekeeper.password.key
/data/system/locksettings.db
/data/system/locksettings.db-wal
/data/system/locksettings.db-shm
To re-enable call audio use TWRP (install zip) to reflash the same version firmware from the Asus website over your current install without wiping. This will restore any system apps you may have removed but you should still have root and can easily remove them again. There will be two errors when performing the flash, which is why I believe root is retained but the system image will be reflashed. Reboot and enjoy
I sincerely hope I have not caused anyone any issues! Or that someone else finds this information useful. I have tested everything in this post at least three times. All testing was done on the most recent Android 7 firmware on my ZenFone 3 Deluxe Special Edition (SnapDragon 821/6/256).

The second issue happens in all the phones/twrp.
It's possible to install the firmware from asus website with twrp?? To update i flash the stock recovery, install the firmware, then reflash twrp and supersu. Didn't know that! It updates successfully with twrp??

Thank you Ryder for confirming my suspicion that the pin issue may have been a more common one with TWRP. This is the first phone I actually cared enough about to use a pin. I was thrown for a loop when I first booted my fresh nandroid restore and the pin I know I've been using was incorrect!
As for installing firmware, with the two errors that occurred during I don't know that you would be able to do full scale upgrade to a higher version. To reinstall the system partition however it does seem to work quite well. I tested this part four times. To do so download the correct device/version firmware to the phones storage, click install, and select that file. After it completes I like to wipe both the cache and the dalvik cache before restarting the phone. The audio issue was unfortunately easily reproduced on my phone, but thankfully equally easy to resolve. This worked for me each time without fail.

You said that the two issues occurred when you restored the nandroid backup and to fix one of them by installing the zip firmware from asus website with twrp... I don't understand. I can install zip firmware with twrp or i have to flash the stock recovery and install with it? Errors may occur using the twrp? Sorry

Everything done in my post so far has been in TWRP. Honestly I didn't even back up the recovery image. TWRP seemed to work flawlessly so I bit bullet and flashed it.
On a sidenote I am currently testing the usability of FlahFire on this device. It appears to create a very nice fastboot installable recovery image! I have yet to restore the image however. I will post my findings here once I have thoroughly tested it.

Ok. I'm interested in flashing zip firmware to update. Never tried that. I thought that firmware can be installed only with stock recovery. The stock recovery can be downloaded in an asus forum website

This is the first time I have flashed anything in almost a year. I got to thinking and this is the most success I have had was flashing a stock image with TWRP! I doubt it will perform a full flash. I believe the errors are most likely for the boot and recovery partitions. As a save my butt reflash the system partition it does work. It sounds like it's time to find some TWRP changelogs!

I don't care about stock images... If i can't flash the zip with twrp to update successfully then i reflash the stock recovery and after the update root again with twrp and supersu. By the way, the zip firmare contains factory images? I thought it contains different kind of files

I lack the knowledge to answer that with enough certainty to even call it an answer! This is my foray into the insides of this phone and I don't want to start posting my hunches.
What I do know is you can flash the system partition using TWRP. I have done it several times. Asus's zips run as a script based zip install. You are offered no options during install. When the script runs you will see two errors quickly scroll past.

Are you creating these TWRP builds? If so thank you very much! TWRP-3.1.1-0-Z016-20170826 seems to work flawlessly! No lag on boot and no known issues after restoring a backup unlike before.
I wanted to post my finding about FlashFire by Chainfire. I have had great success with the fastboot backup! It is the only option I have tested extensively however. I have been running the same fastboot restored phone since soon after my last post on this topic with no issues discovered.

How Do I Flash Factory Image?

It's been some time since I've done this so I'm hoping someone can point me in the right direction. I've had my Pixel 2 XL for like a month now...but since day one I've gotten occasional force closes of various apps. Well next week I'm going with a new carrier (Koodo here in Canada) and I thought it would be a great time to flash a factory image to make sure everything is correct. Also when does Google release monthly updates? Is it the first week of April, maybe I'll just wait and flash that factory image when it comes out. Thanks for the help.

Make sure you have the latest adb and fastboot. Get them from Google...
Go get the latest image and Unzip it. Do not Unzip the folder inside. Move everything you just unzipped into the folder with adb and fastboot.
Now, if you've unlocked and unlocked critical, great. If you haven't unlocked critical, you'll have to. The system image won't install if the bootloader is out of date. Sadly, this will wipe your data.
If both are already unlocked, then open the flash-all file with a text editor and remove the,"-w" and the space preceding, then save the file. Removing the -w will keep your data. Run the flash-all.bat file and in about 10 minutes everything will be flashed.

how to back on stock ....i sell the phone and want all stock...no root no boot loader unlocked ...what is the fastest way pls

First thing!! Forget fast!! You need to fastboot flash a full factory image with the -w still in the script. Maybe even do it twice. Then go in and do a factory reset from the OS for good measure. Once that is done and you know it reboots you can go through the locking command. I would NOT toggle the OEM switch in dev though.

So this has been a a very frustrating experiance but I think I've got everything working again. I don't know how many times I've flashed different factory images and then tried to install TWRP and then install a new custom rom. So I want to explain all of the steps I took (if I remember them all).
0. I couldn't boot into my system but had TWRP installed. At this point I should have tried to get all my data from the sd card via "adb pull /sdcard" .
1. I didn't find any option to fix my system. So I followed this guide to install a factory image (link).
3. I skipped through all of the setup processes and gave my phone wifi. Then I went into the system and did a factory reset.
4. After skipping thourgh the setup again I enabled adb and bootet into the bootloader "adb reboot bootlader"
5. From the bootloader I booted into TWRP by "fastboot boot twrp-3.3.0.0-taimen.img. In the recovery I set the display time out to 300s because for some reason once the phone timed out I could get into twrp any more and the screen stayed black.
6. I transferred the twrp installer and my rom by " adb push TWRP_installer.zip /sdcard/Download" and " adb push ROM.zip /sdcard/Download"
7. I first added the TWRP installer to the flash queue and then I added the rom and then falshed them both. This allowed me to install the rom.
8. For some reason TWRP was not installed. So repeat step 5 and only flash the TWRP_installter.zip
Problems I had:
- In twrp I often got errors that said unable to mount system or vendor. I decided to ignore the error but this thread might help
- Installing TWRP while the stock rom is installed led to the problem that touch didn't work in TWRP
- Entering a pin for the stock rom and then installing TWRP led to TWRP asking for a pin to decrypt my data. Apparently this is not the case if you use a stock image which is older

After flashing stock ROM ota and twrp installer zip the only way to get TWRP to respond to touch is if you disable screen lock and connect to your PC before booting TWRP.
I've found the most reliable way to flash factory images is do it manually with fastboot, latest platform tools installed and a Linux OS like Ubuntu or pop os.
But first do some research and get comfortable with fastboot commands. And dear god don't relock your bootloader unless you're ?% sure it's totally stock.

@schpongo,
Also, a good point to keep when flashing via TWRP is to flash/install ONE AT A TIME. As per the great @Az Biker, you should even reboot to the bootloader after each subsequent flash/install. So, in your case, it seems that you might/should be rebooting to the bootloader three times; one for TWRP installation, one for flashing the custom ROM, and one more for any other subsequent installation (i.e. custom kernel or custom font)...
Also, as it's been said before, but stock kernel doesn't play nice with touch commands on TWRP, and (usually) the only way around it is to reboot into bootloader using the adb command -- as opposed to holding the volume-down button or from an app.
I know you figured this all out already, but it might bear repeating just in case you didn't know and/or to help any other users here...

Can someone give me the easy, simplified version on how to install Lineage (PH-1)?

First off, sorry if this has been asked or covered before. I made my account just yesterday simply to post this topic.
I have no experience with rooting or installing a different OS on phones, but decided to try with my backup Essential.
So far I've unlocked the bootloader using Fastboot and ADB, but can't seem to get Lineage installed correctly. I've flashed twrp but after being in recovery mode and trying to flash the latest image and Lineage OS, it won't seem to boot out of the bootloader screen.
This has happened twice and both times have been able to wipe it from recovery and go back to stock Essential, thankfully. But I don't know where I'm going wrong. Maybe I don't have the latest image or Lineage zip folder? What partition should I install on?
I've even tried using fastboot -w to wipe my phone and it won't wipe it. I can't remember exactly what cmd says but it's something about not finding user data, I think?
I've watched YouTube videos on how to do it, and the videos I saw referenced the thread made by the user invisiblek.
I also read his post specifically and there is still something that I'm missing.
After having reset my phone twice and get it stock and up and running, I'm on the official Essential build OPM1.180104.14
Could anyone with some knowledge help a newbie?
edit: got it working!

Nexus 5x major rooting issues, help!

****** Would really appreciate some help here...
I've tried to install quick reboot (zips), magik, (zips) and busybox, on 3.4 0-0 twrp, and it won't work to boot to system, still says on this version it cannot mount the system. I don't have the perma-recovery file as I cannot find it online, and nexus root toolkit doesn't download it in the dispensaries, latest version.
Hope I haven't knacked it, i also have some screenshots but it doesn't matter as I cannot access the system itself, unless i am missing something it should just boot back to system, I don't understand what I am doing wrong, or have done wrong. Got the img and everything with it.
That said, the mount storage issue is the only thing red, or wrong in the flash, everything else worked apparently, said it installed without a hitch. Which was different that with the standard NRT downloaded twrp, with supersu, as that didn't work.
It just goes back to twrp constantly, can't boot. Help. Really wish I just waited for a response here first. Also I don't believe this is a bootloop, as it just goes back to twrp not bootloader or anything else, probably wrong.
I have been using this vid from the start: realizing that wasn't doing it, magik and a new bionic busybox zip eventually did the trick on 3.4 0-0 twrp, but it sitll won't boot to system. It is probably something obvious, I have been on this for hours today and yesterday, no luck.
only thing i can think of is something to do with: fastboot flash recovery twrp-3.2.1-0-fbe-4core-bullhead.img
basically i flashed the latest version, i dunno if it's supported by nexus 5x.
thanks. uh just please say it ain't bricked.

Anyone?!
edit:
hi all, after immense pain, stress and struggle to get the thing to mount, and trying everything suggested online, it eventually just like "soft-bricked" or whatever, like it was just perma-stuck on the google screen and wouldn't boot to system. i am guessing it's because after a mistake it wiped the system.
i have managed to flash it back to stock, everything is there, and/or redownloading. no way am i gonna bother again, like if it ain't broke don't fix it at this point that would be foolish thought it was perma broke. i'm gonna get a profressional to do it or something, or to give me one to one support to try it again. in the meantime i am going to learn more about rooting and the NRT and all the fundamentals of that.
if anyone here has advice about this still, or articles where I can read about it online, where to learn etc. I'd appreciate that as well, thanks.

issues such as what youve experienced are usually caused by version mismatches. I dont have this device and am unfamiliar with the root process for it, but it shouldnt be too different from any other phone. what is the baseband version of your actual phone?

look at this specific reply in this thread
