Touch screen works in TWRP no touch booted - ZTE Axon 7 Questions & Answers

Okay. This is an odd one for me. bought another axon 7 bc it was cheap. swapped in my old board and battery because it was charging and running really hot. (ive owned 4 axon 7 now, it was the hottest ever) so surgery went fine. upon booting, the touch screen, does not respond to touch. while within recovery (twrp by nfound) touchscreen works perfectly. i really dont know what to do to it. i have tried to restore all sorts of backups, but every one has the same issue. ive tried not including EFS and tried it included. if the screen wasnt working in TWRP, id question my hardware labor, but im kind of stumped. i keep trying to download B19 nougat edl, but the download keeps failing. (thanks tmobile and my in-laws wifi). my question is coming from a functional custom recovery is there a way to flash or restore stock recovery? i know i can EDL eventually, i was just wondering if there is an easier way?
EDL fails to complete using any of the EDL files i have tried so far using
Secondary question, is there any EDL thats works as a necessary starting point? i.e.- on moto devices, many firmwares were not backward flashable. ultimately, i just want to know if i can EDL Marshmallow or if that is even possible. i have attempted B15, B19, and B32 with no success.

you should be able to EDL any update without problems. Use EDL Tool, that one works even better than miflash.
What a mess. ? Maybe an EDL flash on the newer board would have fixed the thermal problems...
Try an IDM for downloading stuff. If the download fails you can simply resume it no problem. IDMs on Windows are crap, but this one works perfectly (on Android, that is):

Pretty much par for the course with me and Axon 7's. Simple op impossible. lol.
I just flashed b32 which Miflash says flashed successfully, yet as was the case after b15N and b2xN the splash screen pops up, the image of stock recovery flashes just for a sec, several red flashes, and power off.
It takes a try or two to get EDL mode after that. i guess tomorrow (left it at work on my desk) the phones original board is going back in. lol.

So i swapped back to the board that came in the phone and touch works perfectly. that board was missing the pink paste on the back of the SOC. after having it run 115-125° F, i decided to swap the battery with my good one and add the pink gummy stuff too. on stock it got so hot it would freeze and shut down, and now bl unlocked on O RR, i have to undervolt -25 global to keep it stable. i did finally manage to get full EDLs to work, but the SOC just seems faulty or tweaked. i imagine it is just one that runs hotter. also, in swapping the screen back, i have concluded that the other board i had must have a connector issue for the touch display. i may try to resinstall it later. kinda tired of screwing with it for now. any input is appreciated. thanks
EDit:
hot board made cool by flashing back as far as i could go, but now it has no IMEI. lol.
UPDATE: finally figured out the b15 full edl i was using was what was killing the screen. flashed back to b20 and screen worked fine. now both phones do not have IMEIs, though. win some, lose some. lol

[Dirty-Santa Root] Bricked Verizon LG V20 Please Help!!!

I have rooted many phones before without an issue, and during the root process for this phone, everything was going great, I flashed SuperSU zip in TWRP and rebooted, since it was the first boot I expected a decently long wait, after about 25 minutes I followed the guide's instructions for Verizon since it did say some Verizon users were experiencing long first boot times. I took the battery out like it said, put it back in, then proceeded to fastboot boot2.img, like the guide said. After letting it sit for an hour this time, I got the idea that something was obviously wrong. After multiple attempts with no success I tried to fix it myself. So far I have learned that on the fastboot screen it says my bootloader is locked again, even after unlocking it. I have tried flashing TWRP as a recovery, just to at least have a recovery boot, that does not work either unfortunately. So as of right now, all I have is a v20 that has no OS, a locked bootloader, no way of booting recovery, I can fastboot with no ADB, and its virtually a paperweight. If anyone has a solution to at least get back to Stock, I would greatly appreciate it! Thanks!
First off. It will say: Bootloader Unlocked: No
Thats normal. 2nd. you are not bricked. You have TWRP installed. You just need to redo some steps.
PM me. and I will help you.
Did you get it fixed?

In his case we needed to redo from step 3.
I managed to un-brick mines after returning sadly from the Sprint store.
First, get to the boot loader screen and try running thru the steps again, especially step 3. You need to make sure you have TWRP.
Use this link to make sure you can get into the different modes (Download mode, fastboot, etc) http://www.hardreset.info/devices/lg/lg-v20/
Once you can get TWRP to show up,then you are good. In the mean time I downloaded "LS997-deODEXd-signed"
When I got into TWRP, I transferred the file to my phone. Rebooted from TWRP back into TWRP and flashed the ROM.
During my reboots, I do get a message saying my phone is corrupt, blah blahblah, but I just wait a few seconds and it will boot up.
Hope this helps.
I had managed to brick mines only 3 hours after upgrading from my Note 4. It took me from 9pm to almost 2am to get it back up again. I can live with the message about my phone being unbootable until someone comes up with a work thru.
Bricked T-Mobile v20
I have rooted many phones before without an issue, and during the root process for this phone, everything was going great, I flashed SuperSU zip in TWRP and rebooted, since it was flash a new rom on it then i get boot loop with TWRP. so i decide to OEM LOCK again after that everything was stuck on my phone just boot loop with LG so any solutions please help me...... THx u for help me.
Kinda nerve wrecking to read about all these "bricked" phones popping up after trying this method lol.. Perhaps I'll just wait until a more tried and true way comes out...
Dirty Santa root is not for the average user who has a couple of experience in rooting.
You have to at least have background on Hard bricking phones to fully understand what you are getting yourself into
For anyone that isnt on sprint that has "bricked" their phone. There are kdz's that will allow you to reflash back to 'stock". Someone had an issue with the kdz, but it was an easy fix. If you failed the process, it can be restored. Just if it doesnt want to boot, just lock and unlock the bootloader...
If your phone doesnt have a kdz, I know TeamDev is working on a custom kdz for such phones. Don't bug him if it isn't finished as I type this.
Anyone that can't get into TWRP, or has failed the process. Either start back at step 3, or if you have TWRP installed but can't get to it, the manual way to get into TWRP is a pain.
Keep your back cover off and hold the volume down button for ease. Now press the power button and as soon as you see an LG logo, let go and repress the power button. Its tricky.... If you get the corrupted screen, pop your battery out and put it back in quick and repress volume down and power. Usually if Im quick enough the first LG logo will hang a lot longer than usual and that gives me time to enter TWRP. A factory reset screen will pop up. Hit Yes twice.
Please help urgent

What does that mean? Not for the average user who has a couple of experiences in rooting.
I've only rooted 2 phones, this is my 3rd (maybe 4th). I am on Sprint. Instructions worked fine for me. I did have one hiccup, but it was my fault, and I was able to root just fine. I've been running for a few months now.
I have not flashed any custom ROM yet, I'm going to wait for the next major version of Android to come out. The only mods I've done so far are Titanium Backup install so I can remove Sprint crap.

it means dirty santa root got a high posibility rate of bricking a device compared to other root methods for other devices and if you have no experience in bricking phones before then you're screwed if it happens to you
Actually, if you follow the directions, almost none of the problems create a true brick-- which means unrecoverable. For most of the cases, you might get a soft brick, meaning you have to back out, use a KDZ to repair it or reflash something else, or start over from scratch and try again-- but usually (maybe with some help from here) you can pull the phone back into a usable state.
I would hazard to guess for the vast majority the process works fine, maybe with a hiccup, but I've not seen many reports of a truly unrecoverable brick from this method. It's complicated, yes, and you need to be ready to read a LOT to understand what's going on, but it seems pretty difficult to end up with a $700 paperweight with this.
So i have been trying tonroot my sprint lg v20 and everytime i try and go to the phone on mobile terminal to enter id
Then enter the apply patch /system/bin/atd /storage/emulated/0/dirtysanta i get this message and i cant go to step 2 to boot into recovery
Any help would be appreciated: i have a sprint v20 and i wanted to know if i have to flash the stock sprint rom or can i just flash lineage rom following this guide? I have it running on AT&T and i want to keep it on AT&T...
can you please assist
Could you help out, please? I don't believe I have hard bricked my LG V20 H910. However, I have read and tried all of the unbrick info out. It seems my screw up is unique. I completed dirty Santa then went to flash a custom. in the boot between that. I get a black screen and cant do anything even download mode will not come up. My PC does make its usual noises when i connect or disconnect, but my phone does nothing.
Ok, I managed to brick mine too. It's a VS995, it was running stock 1AC. I used the LGUP tool to downgrade it to VS99512A, and then did Dirty Sanata and TWRP. After booting into TWRP I decided to try lineage OS with Android 8.0, I did not make a backup of the Stock ROM, which was very stupid. Lineage OS 15.1 flashed but I had no cell service so I panicked and instead of wiping it in TWRP and using the backup of stock I should have created, I just opened LGUP and tried to downgrade it back to stock VSS99512A. Well LGUP said it worked, but when it went to boot it would hang at the Verizon logo with 4 pastel dots. Device manager could see an ADB device and I could connect to it with ADB. So I did and read the logcat. I could see it was trying to update as part of the rollback, but it appeared that some components from Android 8x could not be "upgraded" to Andoird 7.x. There was a repeated error about failing to update SQLite instance version from 3 to 1.
The one feature that could fix this is if the refurbish function worked with any of the VS995 KDZ files we all have access to. But alas, none work instead we only get the upgrade function... or so I thought. Somewhere in my search for the past 2 weeks I found a modified LGUP https://forum.xda-developers.com/v20/how-to/guide-patch-lgup-to-unlock-features-t3652222
**Please be warned what I did was absolutely ****ing stupid, and it was sheer luck I didn't screw anything up.**
From what I can tell if you only flash ("LGUP Upgrade") the KDZ from the same model it never clears the partition it just adds to it. My problem was there was stuff from lineage OS 15 stuck on one of the partitions that was making the rollback to stock fail because it kept saying it couldn't update the SQLLite DB from 3 to 1. So no "upgrade" within LGUP would work because the upgrade function does not clear internal storage. But the link above is to a version someone modded so you can force a partition update from any KDZ onto the system. So I started playing around with forcing KDZs from other models onto my VS995, and I noticed when using the Partion DL function with non-VS995 KDZ files it would say something about the partition changing. All I can assume is that the partition layout is so different on each model and it forces LGUP to re-partition the storage.
**Again I state for the record this was stupid, and I'm only fortunate it worked.**
I forced Partion DL of H91510d_00_VTR_CA_OP_1110.kdz, then H990N10b_00_OPEN_HK_DS_OP_1017.kdz, then back to VS99512A_06_1114_ARB00.kdz, then when it booted it gave the Verizon hello, and moved on finally but the setting service kept crashing while it was trying to load the Secure Boot screen. So I yanked the battery and went into the boot menu and did the Factory Reset function, and it worked.
Lesson learned, always make a backup and don't be so hasty to use tools that aren't fully functional (LGUP).
Perhaps what I've done may help others, maybe I've found out how to reimage or unbrick our V20s. Or maybe I just got really stupid lucky.

Unusable A2017G

So i have this A2017G owned by a cousin of mine. He had never tempered with anything except updating OTAs from the settings app. Meaning Stock everything and BL locked. Now, all of a sudden his device lags a lot (after the N-B06 update). When booting the device the boot animation lags like crazy. And it almost never gets past the boot animation (always restarts at Axon 7). The times it does reach past the boot screen, the device hangs after a minute or so and restarts.
Things that i have tried:
# Factory resetting through stock recovery.
# Downloading update.zips from ZTE and trying SD Card update trough stock recovery. Which always fails saying Signature verification failed.
# Booted to factory test mode and tried adb devices on cmd. Nothing comes up as there is no new device on the device manager. Also no sound.
# Booted to EDL mode and flashed N-B06 from this post: https://forum.xda-developers.com/axon-7/how-to/guide-ztea2017v2-0-0b08-t3658636
Nothing helped. Same old lags. And of course, the device is unusable.
What to do? Suggestions?

Get a new phone. Unfortunately I think it's some hardware that is broken. But in case it's not try to flash b05 instead?
I don't see anything else you could do since adb doesn't seems to work. I'd just RMA it with the warranty still being in effect. And if it was purchased trough amazon you'll probably just get a new one ! (that's what happened to me last time).

Did you try downgrading through EDL? I'll post the link to MM B10 for you to install through EDL, see if that helps. I seriously doubt that it's a hardware issue since it would not even boot if that was the case (take the Nexus 6P and 5X as an example: big cores busted and the phones wouldn't get past the boot logo).
Don't unlock the bootloader if you can't fix it, it'd make matters worse if LOS-based ROMs didn't work.
Edit: Here are a couple of links for B10 from 4pda. should be the same file:

I have tried this EDL package as well. Most of the time it says can not found programmer file. Only once it said can not find hello packet, reset status. That also ended up in error.
The N-B06 EDL package flashes fine. But the problem still persists.
I have also tried replacing N-B06 recovery.img with TWRP recovery.img and flashed it. But that just bricks the recovery.
Currently the 2 EDL packages i know are these two. N-B06 and MM-B10 for the G. The N one works fine while the MM one doesn't. Do u have any other EDL packages?
I too think it's a software problem since he has never dropped the phone and only used it for 2 months.

I got that package from 4pda. if you go to the 4th category brick repair manual, then enter the link that says "Qualcomm drivers and MiFlash" it will redirect you to 4pda. no need to translate: just open the spoilers (I think it's the 2nd) and you'll find all of the images. You obviously have to use the A2017G ones. there's B10, i think B11, B05, B06 and maybe another N package too
The thing is that it'd be best if you could downgrade to Marshmallow, as that would probably do some other stuff that N packages don't do.
Do you have an external SD card plugged in? Try to use without external sd, i already had lags because of a defective sd card (that couldnt be rescued nor reformatted )

I was gonna suggest that, but a read-only SD card wouldn't provoke that. I had one that got read-only after using it as swap for a long time, and you would only notice in twrp (booted in ~2 minutes). If he was able to try to install a system update through the recovery, he was able to write to the SD card --> it's not dead

Thank you for mentioning there is EDL packages in 4pda. I just tried the packages that are available for the G variant on 4pda. But the problem still persists.
I was thinking that too. Trying to downgrade through EDL. But so far i've found only one MM so far, B10. But that ends up in error during flashing process.
Is there any way to install TWRP through EDL without unlocking bootloader? Also, is there any way to unlock BL without adb? If i could at least unlock the BL, i could flash twrp through EDL. There are EDL packages available for flashing TWRP.
Thanks.

Mabey but I think as in my case that something has happened with the hardware. I think it is a hardware's fault that has come up to the surface when he updated the phone like it did 2 me. But hey, it's just my theory.

The problem is axon 7 is not available in our country. If he has to rma it then he has to send it to a relative in Sweden. Then the relative can do that for him. That's why he asked me to do what i can to revive the phone. RMA is the last resort for him.
Now, i guess i will give up and tell him i did everything i could.
Anyways, thank you all for helping.

Screen Not Responsive After Flash ..... +

Hey,
I've been on quite a journey since I attempted to flash the Treble rom for newbies. My phone eventually ended up as DFU'd but, I brought it back to life after a following the DFU Unbrick - Disassembly guide. After doing this, the screen was not responsive to touch at all at the Welcome screen of the EDU ROM. So, my adventure continued as I took the phone apart several times again to make certain things were connected, not damaged, etc..
After flashing TWRP I concluded the screen itself must be fine because I could use TWRP using the screen/touch. I have since tried flashing several different roms, tried many combos of unlocking the bootloader (again, because I assume it was already unlocked due to the bootloader warning screen of can not check for corruption message), tried flashing bootstack and the stock rom from DrakenFX. Used MiFlash, EDM Tool to flash various items.
Each time and currently, when it boots to the Welcome screen it does not respond to touch.
Can anyone please help me with this?
Thank you!
I remember this happened to me some years ago with a different phone, and it was a bad flash.
I resolved it by flashing the stock firmware again.
What did you flash with MiFlash? Stock firmware untouched? You must do this, try with B35 untouched. Don't flash stuff with TWRP.
Untouched? Is there anything on here like that?

Those are "untouched" system images. Replace recovery.img with a proper TWRP version before flashing:

Yeah, unfortunately the very first link (since I am in the USA and have a U version) is the very stock EDL version I used with MiFlash rightg after I was successful getting the phone out of DFU. I have tried flashing it twice after and still nothing.
Thank you for helping!!!

Sad to hear that... Maybe you can try again? Who knows, with a little bit of luck...
Or try another version, like this one:
https://www.androidfilehost.com/?fid=890129502657579386
btw, did you try every single spot in your screen while in TWRP? Maybe some pins in the connector are broken and some parts work and others doesn't?
And for the sake of it, you could try discharging your battery completely.
Last thing I can think of... is to restore the stock recovery and apply the official update via sdcard:

Yeah, the entire screen works perfectly in TWRP. I disassembled it several times before when I thought I may have put it back together wrong or damaged something so, the battery was removed those several times therefore, no power.
I'll try the stock above. I'm actually trying another stock rom atm --- flashing from sdcard

Well, EUREKA! I found I had saved the first files you were supposed to load when the Axon was first unlocked ( file name STEP_1_3-B20_FULL_OTA). Flashed it and the screen works fine. Now, I have to remember how to update it...lol I've unlocked the bootloader in Developer mode and I should be on my way..... fingers crossed.

Strange.
Nevertheless, congratulations. Happy for you.
Well, it's great that I now know the screen/hardware is fine but, I am unable to get any further than version B20. OTA doesn't work, the other files to flash (STEP_4-B20_to_B27 and STEP_5-B27_to_B29) won't flash and get aborted due to it expecting a certain version. I've tried DrakenFX Bootstack and then Stock System and it boots to the Welcome screen but the screen is no longer responsive again.
I have been at this all day again and it's shaping up another all night too. I am so baffled!
Restore to stock firmware your phone came shipped with.After that update trough ota or sd card package and maybe dont flash Treble again,its broken

i wish i had seen this sooner, because i have this same exact problem on one of my boards. it will update perfectly to any of the MM sd card update files (see rootjunkys bl unlock video, thanks @Tomsgt) but the board/phone will not retain touch functionality on anything higher than mm b29. i had lost my imei on that board, and actually swapped to another one despite eventually regaining it simply bc i wanted to be on Oreo ROMs. if you find a fix, id love to know about it. i flashed and reflashed every update, sd card versions, edl versions, and OTA updates to no avail. Nougat or above, touchscreen didnt work... mine was a gold a2017u. good luck, man. im glad im not crazy.
Sorry to bump an old(er) thread I started. I wanted to ask if anyone has found a solution to this issue yet?
I have since tried updating using OTA to Nougat and the screen doesn't respond so, I had to flash back to Marshmallow B29. Thank you to anyone who might have an idea!

6T keeps 'crashing'

So I just picked up a clean used International 6T. Was going through the root and update (I did the Android 10 update through Oxygen Updater) process and all that, things were going great, then out of nowhere they weren't and I had a complete black screen. I've literally been up all night trying to fix this thing, then again out of nowhere it actually boots, and I was able to use the MSM tool to restore it to that earlier version, then proceeded to get back up and running again.
Thought, phew, dodged a bullet. Nope, after getting rooted and TWRP installed, transferring a bunch of files over from my old SD card and restoring apps through Titanium (again, everything was going great again), and yet now all of a sudden I'm back where it all started earlier, stuck at the 'The boot loader is unlocked and ....' boot screen, it just hangs there, I can reboot into recovery just fine, but no operating system.
I'm literally about to pull my freaking hair out and try and sell this thing if it's going to keep doing this, I've never had a phone act like this one has (prior phone was a Nokia 8, headache). I have friends/family who haven't heard from me in a couple days now because I'm out of a phone and I need to get this thing working stable.
Can anyone help or shed some light on why this has happened again? I didn't update to 10, left it on the last stable Pie (begrudgingly), didn't flash any custom rom or anything, it was restoring most of the titanium apps just fine (some just hang there, not sure what that's about) and now I can't reboot into the os. To say the least I'm beyond pissed and annoyed at how much time I've lost on this thing.
Please please please help if you can, I'm not a newb to rooting (already rooted this one twice) but I don't know what to do at this point.
Thank you in advance, let me know what/if any info is needed.
Edit: I think I know/understand partially that magisk is to blame for this and reinstalling it fixes it, though I just did that through TWRP and it's still stuck on the boot screen.
Edit: Yup, right back where I was, device now shows as HS-USB QDloader..... in device manager. What gives? I have to use the MSM tool again? Why? Why is this happening...I've never had this much trouble with a phone
Try a clean install. Don't root and don't restore the titanium apps. Install them fresh. If your problem persists then it may just be hardware. But something you are restoring may be causing the crash due to the way it is trying to restore the app data.
I had similar problems. For me it was my self-created magisk module that ran without problems under Android 9. As it seems, there are also problems with modules from the magisk repo.Could be the case with you.
Clean install of the apps, after doing another MSM restore? And trust me, I won't be installing ANY other magisk files other than just the magisk.
Is there any way to save all the work I just did though without having to start over again via MSM? I'm guessing not....sigh
Grrrr...ok before the MSM tool worked, the phone was just unresponsive. It's back at that stage where the MSM tool times out and doesn't do a darn thing to save the phone.
I swear this thing is all over the place, now I'm in the bootloader, yay. I guess I'll try a wipe in TWRP and start over.
One thing I forgot to ask, is magisk the ONLY option available for root?
The question would be, how did you root.
TWRP is not working when you don't follow the instructions which involves OldKeysFlasher.zip.
Otherwise you have to flash Magisk with a patched boot image, be sure uyou have one for OOS 10 Stable.

I hope that anger is directed towards yourself because you can't hold the device or its manufacturer responsible when you get into the flashing game.
If you had done some reading, you'd know that TWRP doesn't play well with Android 10 and upgrading from 9 takes a very specific procedure. There's a dedicated thread for it even. Happy searching. You may also want to take a peek at my posting history for some pointers.
One more thing, are you absolutely sure it's an international device and not a converted T-Mobile version? Because that can cause a major amount of troubles.
Wrapped with delicious Fajita [emoji896]
I'm well aware it's my own doing, part of the frustration is having too many sources of information all claiming they fix a 'thing'. There's the "fix it with fastboot" camp who doesn't like MSM, and there's the MSM camp that helped me the first time. Phone is currently dead/black screen, going to try MSM again, and will check out the info you provided.
And I'm sure, double sim tray, does not flash a pink tmobile screen and/or no branding of any kind on the phone related to tmobile.

Just remember that dual SIM trays are easy to get and if it's been converted from TMO to international version there will be no indicators till n you try to flash A10. Best bet would be to treat it as a converted TMO, if it is the info in recovering and flashing a TMO device will work and if it's truly an international version it will work too. Best of both worlds.
I'm 99% certain, by the label on the box, etc. Regardless, I'm to the point now that I can't even get it to boot to TWRP after 'fastboot flash boot twrp.img', it just does nothing and when I try to boot to recovery it bounces right back to bootloader. I've been trying all afternoon to fix it with no luck.
Was android 8/oreo good on these phones? That was my sweet spot and I'm just gonna downgrade if possible, there's too many things I don't like about 9 and 10.

"Warning" Total Brick After Flashing Android 12 Beta

My phone is totally bricked, and it will not respond to anything, a totally black screen, after flashing Android 12 Beta using Fastboot.
I was on A12 Beta, I hated it, I wanted to flash AOSP, it did not work, so I decided to flash OOS 11 from Fastboot, it did not work either, I tried EDL MSM tool, it did not work either, it kept on booting into fastboot, fastboot loop, I extracted the payload.bin from A12 Beta using payload_dumper, I ran flash-all script, the phone successfully booted into fastboot the at the first section from the script, flashed the remaining files, when the phone attempted to rebooted for the final time after the script was completed successfully with no errors, the phone died at the final part of the script, which is the final boot, and it will not respond to anything, no sign of anything, complete black screen, I tried EDL mode, I tried everything, it's not responding to anything, I opened the phone and reseated the battery and the motherboard, still nothing. So Sad
Flashing roms via fastboot never works for me.
You should read the threads next time, there is no custom rom that works from a12, every rom need a11 as a base. And yes the a12 custom roms too.
Your only option is and was the MSM tool.
I was in a similar situation, i got my phone back with pressing vol +, vol - and power for i think several minutes while connected with a third party cable to my pc with msm tool where i already pressed start.
It started to flash everything somehow and i got a working phone.
Good luck.
A quick note: EDL mode will show nothing nor vibrate. The only way you know it's in EDL mode is that it's going to show up in MSM tool.
Just try using the MSM tool.
Start the program.
Hold the Vol Up and Vol Down at the same time for 5 seconds, then connect your phone to your PC.
If it doesn't show up in the MSM tool list, just hit Enum.
If you see the phone just click Start and wait for it to complete. For me it's usually around 300 sec.

Yes, OSS 11 is a must, I have tried downgrading and I guess "downgrading" is the issue here.
I have been using OnePlus since its first release, I am very familiar with it,
I have tried everything, but nothing works, I read more about this, and looks like the circuit is out of order, it will not pass anything "signal", especially to the screen.

Thats possible im not a pro. But from my understanding, its nearly impossible to brick a phone which is using a/b partitions via fastboot.
You tried a third party cable?

My last suggestion is to try to charge overnight and see if things are different tomorrow.
Other than that, only option is RMA as it's still under warranty.
Forgot that you already opened up the phone, so most likely they'll throw it back as it was opened by an unauthorized party.

OMG
Nobody believed me in the threads when this happened (end of Feb/early Mar). This wasn't spiteful in anyway either. It was more/less just unheard of and my methods and adherence to the most vital aspects for EDL recovery, were justifiably questioned. Unfortunately, in my case, I have had years of experience jacking-up my devices and I immediately knew/felt there was something different with this situation. In my situation though, when introducing how I had entered the predicament, it was strictly self-inflicted, complacency at its finest and terrible terrible timing for a well overdue slap-in-the-head to interject itself into my life. Did I mention I was OMW to Disney with m/wife, kids.....driving. I had 7 days to deal with at Disney with a pre-planned, fresh-flashed A-12 OP8....I ended up using my LG G3 which I had been spending significant time trying to develop into a dedicated full-fledged Kali device (had success w/that actually).
So seeing these posts and threads now is dis-heartening but vindicating. Had I not flashed A-12 the way I did, I would've been fine. I can not blame OnePlus for anything, I bought a locked-down (carrier unlocked) Note 10+ in its place and its driving me bonkers. I thought I would be able to tolerate the non-rootiness, but I've been flashing since my 1st smartphone, one of the 1st Galaxy's, the Verizon Fascinate.....good ol' Jelly Bean. Meanwhile, my lifeless OP8 sits on my desk upstairs surrounded by older devices.....its the only one that doesn't turn on.
