Oneplus 8 fastboot only - OnePlus 8 Questions & Answers

I have a t mobile variant that is sim unlocked and bootloader unlocked.
I wanted to convert to a Global version however it failed because I apparently had the wrong oem software.
I used all in one tool which worked great for everything else I needed but here is the problem; I can only boot into fastboot mode and crashdump mode. When using all in one tool I chose to wipe the device before installing the new software
I also cannot get into EDL Mode to use the Msmdownload tool even though the correct drivers are installed to use this tool.
Anyway out of this? Thanks...
Aslo; I have tried fastboot commands with no luck...

You need to msm using edl. If you are bl unlocked, flash a custom ROM to get booted and maybe try again using proper tool?
Also, try different USB ports, cables, etc. You should be able to boot into edl with hw keys and connect to msmtool

As I stated I can not get into edl, I tried all the the other things also, cables, ports. I did not know I could have flashed a custom rom at this point, phone was not rooted either...
Oneplus has it now for repair, they are about 300 miles from me, or the service center is?

Not sure if you got this fixed but boot into fastboot, the use "fastboot boot" to boot into AICP Recovery. Within recovery eanble ADB, then "adb reboot edl". EDL mode is just a black screen and your phone will exit it and try to boot after a few seconds if the drivers are not installed so its easy to miss. If your phone can boot into fastboot it can boot into EDL.

I do not see that feature listed? Phone would not boot into normal recovery, it went right back into fastboot.

Also if you had read through the posts you would know that I already sent it to 1+ for repair, they have had it a couple of days...

OnePlus repaired my device for nothing which is nice however It's now sim locked and at first try T-mobile says this device does not qualify for unlock!!! T-mobile also said they are looking into it because it was previously unlocked and it may take a week to get a reply.
I called OnePlus and their response was it's not our problem (more or less) I sent them a unlocked phone and they completely ignored my request to load the global software on this device, they did what they wanted to, they could have contacted me at any time..THANK YOU OnePlus.

Stuck at LG logo

i booted into recovery, made a full backup, wiped everything but internal storage, flashed to lollipop 5.1 but decided to go back to my backup. so rebooted into recovery again and restored the backup. everything seemed to work correctly but after rebooting phoned stuck at lg logo. so i rebooted into recovery by holding "volume - and power" and the factory data reset screen came up and i confirmed that i wanted to reset phone, expecting it to boot into twrp but it went to the the black screen with the android on his side (or something like that), which i assume it did do a factory reset.
so still stuck at lg logo with no custom recovery anymore apparently. among other things, i used srktool to nuke download mode, so phone immediatly goes into fastboot mode. now im trying to use the "fix fastboot mode" but it just sits there saying waiting for device even though i have phone connected to computer in fastboot mode.
is it likely that if/when it did the factory reset, that would disable the usb debugging setting and that's why srktool just shows "waiting for device"?
im betting that your OS got corrupted. You can try to reflash your ROM, or you might be relegated to going into download mode and reflashing the OS back to stock. I have a link for the LG recovery tool and the stock 4.4.2. All youll need from there is towel root and the recovery i have in a separate post

uninstall the usb driver and let windows find the correct driver for it and follow the stuff in the link i provided after the computer recognizes the device. If that doesnt work do the stuff in the link on another computer or try a different cable. If you can get to download mode, youre likely ok. The issue is either the computer or the cable, not the phone.

Hard bricked LG D686 - Tried with test point method phone is detcted by PC now but...

Well I have tried every way to get my LG D686 up and running again before that let me revise how I got here
1 - i rooted the LG D686 in 2016, it worked well for a year until one day I had got a certification boot error msg on start up and had no access to bypassing that except the download mode
2 i downloaded a firmware for D685 instead and flashed it with LG FLASHTOOL. It got hard bricked. When ever I would connect it to the pc it would just connect and disconnect repeatedly. it would not turn on or go in recovery or download mode nothing
3- then i tried to use this method here https://forum.xda-developers.com/optimus-g-pro/help/exclusive-solution-lg-d686-dead-flash-t3330691 . I opened the phone managed to short the resistor to ground and got the PC to recognize the phone in mtk mode. Used SP flash tool flashed it successfully but the phone still wont turn on and even tried a hard reset.
4 - I only want to know if its bricked for good or is there still a chance. The mobile repair shop says hardware and software is gone for a toss , will cost allot to fix, however that was before i tried the testpoint method here https://forum.xda-developers.com/optimus-g-pro/help/exclusive-solution-lg-d686-dead-flash-t3330691. Since I was able to short the resistor on the mother board now the pc detects my phone and never disconnects (in MTK mode) which is a good thing ( i have closed the phone so for now its assembled, i have been able to do a format/downlad 100% successfully with the phone assembled
Do I have a bricked phone for good ? or is there any chance?
I have also attached photos of my progress but my phone will never turn on be it fastboot mode , recovery mode, hard reset, no vibration too. Once I even kept the phone charged for a whole night and checked the battery voltage with a multimeter and it says about 90% charge again that was before i tried this test point method, now if i keep it charged on the charger adaptot the back of the phone right near the sim card slot is never warm as before. its cool which i feel its not being charged now. but if its connected to the PC yes , the area near the simcard slots is warmer, so i guess its getting charged.
I have d686 scatter firmware files from A_1stâ„¢ Support Team
I have SP flash tool (tried latest one as well however this version works well for scanning emmc.txt)
drivers are detected properly on PC . i have attached an image for that as well
I apologize if creating this thread is breaking any rule violations but there was no reply on the page/ thread i was seeking help for hence I thought I will start a new thread

Any one have any idea the hardware needs replacement ???
Is this phone to old for an answer ? Just a simple yes or no . Is it bricked for good that the mother board needs to be replaced ? Or is there a chance I can recover it ?

Any way to enable USB debugging if I can't access the OS?

Hey, my friend has a Pixel 2 that seems to have gotten bricked today. His phone was working fine all day but when he tried to unlock it to check the time, it was suddenly in fastboot mode. He was running stock android, and has never flashed any custom ROM/software to it, nor unlocked it:

I can't open recovery mode or boot the OS from fastboot. The only option I can access is the "barcode" one. I've been trying to flash a factory image from google(as I've done several time for my Nexus 5 and Nexus 7 using the fastboot/ADB from CMD), but currently ADB won't recognize the device(probably because USB debugging and other developer settings are off/have never been accessed at all), and Fastboot recognizes the device but can't perform any flashing to it because it's locked. I also tried deuces script from a folder with all the factory .img files unzipped etc. I also updated the USB drivers in windows, but basically every step I can find here, on reddit or on stack overflow mention enabling USB-debugging and OEM unlock in the settings, which I can't access. Is there anything I can try or is it per definition bricked?

Have you tried using the OTA instead of the factory image? That might give you a workaround to get it functioning again.

Have you tried changing your usb cable and the port its plugged into? Its stupidly simple, but has solved nuuuuuumerous problems I've had with manually flashing.
Other that that, I think you've covered a lot of bases. Are you sure you can't get into recovery mode tho? I was only able to get in by unplugging, full power off, then using power + vol dn for bootloader mode, then selecting recovery mode. You might be able to do some flashes from there.
Also, adb only works in the OS and maybe recovery mode. Fastboot only works in bootloader mode. I'm not exactly sure if fastboot needs to be authorized. Adb does though.

ASUS ZENPAD 3S 10 Z500M Bootloop (HELP!!!)

Hello!
So i got my asus zenpad 3s 10 rooted (with magisk) a long time ago. I have the bootloader which has the normal mode, fastboot mode and the recovery mode. However, i forgot if i had the custom TWRP or not. So, i had this device rooted for like 1 year now. But, for some reason my device keeps rebooting. In hopes of fixing this, i updated THE MAGISK MANAGER and rebooted. Here comes the fun part, my devices is stuck in a bootloop and now i don't know what to do. Getting into recovery mode says 'NO COMMAND' and a broken android bot. Fastboot mode gets stuck for hours and i don't know how to access it cause adb can't recognize my device when i connect it to my PC. I don't really have the model number and i can't get a custom patch for magisk (it might me in the tablet WHICH I CAN'T ACCESS ) I really am desperate right now since i don't have money yet to buy a proper phone.
Thanks!!
Re-flash Stock ROM to get rid off of all modifications you applied so far.

I can't connect it to my PC, adb doesn't recognize it for some reason
I can't even find the stock rom cause i forgot the build number lol. It maybe in the internal storage which i can't access
It should be obvious that ADB doesn't work on bootlooping devices.
If you can find a suitable Stock ROM then you might use Asus Flash Tool what relies on Fastboot to re-flash the tablet

Is there any way i can find the stock rom without accessing the tablet itself?

What the hek is going on?

I've got a Moto One 5G Ace that I picked up from eBay. It's an XT2113-2 according to the Recovery Mode 128/6. I guess the carrier was T-Mobile because the annoy screen always comes on when I boot. Fastboot lists it as
NK0T4M0308 fastboot
but when I try and write the recovery.img I get
fastboot flash recovery recovery.img
Sending 'recovery' (102400 KB) FAILED (Write to device failed (No such device))
When I try and use the Recovery and Smart Assistant(Windows) from Motorola
the IMEI doesn't match to the firmware
And it's stuck on Android 10, when I try and update from the phone it says it has the latest version of Android
When I try and run Rescue and Smart Assistant(RSA) and boot to the Recovery mode it soon drops and says it can't connect to the device
Mobile Assistant is installed by RSA but after RSA tries to detect the device in Recovery Mode but can't it can no longer detect the USB when it's attached. I need to reset the device so I can go through the entire process all over again.
Please help I don't know what's going on or how to fix it

You have an engineering phone. It cannot be updated via regular ways.

So what irregular ways can I employ then?
Send it to someone who has the tools to flash it. I don't know anyone but perhaps someone on the Telegram channel does.
Just in case anyone else comes across this problem too. The internal hardware is not the same as the model would indicate with the model number it's entirely different. So in other words, it's an entirely different phone, it can't be flashed to anything. It's like comparing apples to oranges they are in no way the same.
In Developer options, does it say "Bootloader is already unlocked" under OEM unlocking?
Does it still fail to load recovery if you run "fastboot boot recovery.img" so it says "Waiting for device...", then plug the phone in while holding down the volume and the phone is shut down? Even retail kiev can be really finicky in fastboot mode.
Really cool find in any case.

it would be cool if I could image it, but the internals don't match to what it actually is
but yes it does say the bootloader is already unlocked
