HELP: Rooting Essential PH-1 on android 9

Guys, I'm at my wits end here. I don't know what to do. And it's driving me crazy.
After saving for 3 months, I got a used Essential Ph-1 from craigslist (for sprint). It came with Android 9, and a February 5, 2019 security patch.
All I want to do is to root the phone. And I have tried everything in my power to get it to work. It just does not. I have unlocked the bootloader, I'm seeing the device in adb and fastboot, but unable to sideload, or flash anything. I've been following different threads on here and youtube looking for directions, but my phone will just not do it.
Can someone please help me? I will send my phone over to you and pay you to have it done. I've tried almost everything to do it, and nothing works. I've even tried to flash android 8 and 7, it still doesn't do it. Someone please help me. I don't know what more i can do. Any guidance is appreciated.

Can someone please help me? I don't know what more to do. Please.

Can you temporarily boot to twrp?
Are you using fastboot.exe from the essential ph1 driver folder?

No. I can't sideload or boot into anything other than the android 9

I also bought my PH-1 on CL, but it was an open market version. I can only outline what I found on this forum, and what worked successfully for me... I assume you are on Windows. First off, make sure you install the drivers provided by Essential, and use adb/fastboot that comes with it (it gets installed and put into the system path when you install the drivers).
I didn't care about TWRP, so the only thing I needed was root. So, after unlocking bootloader (and also unlocking critical, as recommended), I simply followed the steps to install Magisk, which are really straightforward:
https://topjohnwu.github.io/Magisk/install.html
Just use the "Boot Image Patching" section.
That's it. Works perfectly, and I just need to repeat the patching after OTA updates (there is a thread about this procedure specifically).
If fastboot flashing doesn't work for you for some weird reason, I don't have any good ideas about that, sorry! Sounds like you are able to get into the fastboot mode (since you are saying you can see your phone in the device list), so why it wouldn't let you flash is kinda baffling...

I tried that too. But it kept saying unable to unpack boot image | installation failed.
I tried it with the stock images from the Essential website, both the OTA and fastboot versions. I'm getting the error for both files.

I would suggest checking out the PH1 Dev telegram group https://t.me/EssentialPH1DEV . not only will you find pre rooted stock boot images along with ones with TWRP as well you will also find help flashing them if you need it. Hope this helps you out.

Thank you everyone for all your help. Special thanks to kt-Froggy. I got it to work. I had to change my usb port from 3 to 2 and i was able to get it to work!

Bricked my Chinese OP6t (A6010) and not sure what to do. Help??

I was trying to help a friend out by installing the international OS on his new OP6T (A6010) because I know a friend who did it a year or two ago and it worked perfectly. We thought it would work out but I couldn't get the firmware to install using the normal system update--it said that the firmware was lower than the currently installed firmware and therefore couldn't be installed.
So, I tried downgrading using the msm tool (I didn't realize the Chinese version was different...) and now it is stuck in a boot loop saying "build version and HW version is not match!"
What options do I have here? I didn't install TWRP (I was going to but tried the MSM tool because people were recommending it on many other sites...but were only talking about Tmobile and Global variants so I didn't realize Chinese was an entirely separate one).
Is there any way to fix this?

You can get it into fastboot right? I'd push the latest official fastboot ROM into it via ADB.

No, when I hold any combination of buttons, it gives me the error message. I can't do anything with it at the moment.
I got it to flash "fastboot mode" for a moment, but then the error message went up again and black screen.

That's weird, fastboot should be coming up before it tries to load the OS, you're going to be left with reflashing (in your case) HydrogenOS via download mode and MSM.

Thank you for the information here with this. Are all msm things specific to certain firmwares or is it possible to throw a firmware into an msm thing? I'm not sure about this one yet.

I have a A6010 I have used this to go back to Android 9 with out issue.

Thank you for your help here.
Unfortunately I keep getting the same message again and again in all of the msm tools I've tried: images do not match with the phone.
I'm not sure how I've done it but I've messed it up badly and now not sure how to fix it.

You're going into download mode correctly right? Holding BOTH Vol buttons while then plugging into the USB cable thats already in your comp?

Yeah, I was able to get it recognized by the computer and the msm software. It was just not accepting it.
I actually finally got it to work, though, but using the patched version of the msm tool that Tmobile users were using to install the international firmware, because it ignores the check for hardware/firmware matching and just forces the firmware on there.
It took two different msm tools/firmwares but finally it worked out. It was an incredibly relieving sight to see it boot up and not immediately go into the same bootloop again.

Glad to see you got it going.

Good day, please I got into the same issue of hardbrick on my oneplus 6t chinese variant. Please would you be kind enough to give a break down on how you got it to work. And were you able to finally install Oxygen OS?

Disclaimer: By attempting any of the processes listed in this thread you accept full responsibility for your actions. I will not be held responsible if your device stops working, catches fire, or turns into a hipster and claims to have been modified before it was cool.
Hi everyone, similar to the previous threads for
OP3, OP3T, OP5, OP5T, OP6, OP6T, OP7, OP7PRO, regular OP7T, T-Mobile OP7T, regular OP7TPRO, T-Mobile OP7TPro 5G, regular OP8, T-Mobile OP8, OP8Pro and OP Nord here are the EDL packages (also known as MSM tools or unbrick tools) that can revive a bricked OnePlus 8T.
You should also be able to rollback your phone to a previous release of OOS with them if for some reason you want to go back to an older firmware
You can download the following versions:
KB05AA tools (international firmware):
ANDROID 11:

Tips:
While crossflashing does not seem to break your /persist unlike on 8-series, it is advised that you back it up before attemting to do so as fingerprint reader may give an error related to enrollment issue. You can do so by using dd if=/mnt/vendor/persist of=/sdcard/persist.img (you must have root access, which is not something I'm going to explain here) and moving it to your computer/cloud.
Instructions:
Launch MsmDownloadTool V4.0.exe.
Windows 7 users may use MsmDownloadTool V4.0_Win7.exe instead, but it hasn't been tested.
On the login prompt select "Other" in the dropdown menu and click on Next.
Wait a few seconds until main window shows up.
Click on Target button and select O2 while using global tool or India while using indian tool or EU when using european tool.
Press Start button (this is done so that device will be "captured" automatically by tool instead of going back to normal boot after 10 seconds)
Power your device off.
Let it cool down for one minute.
Hold both volumes in to get in Qualcomm EDL mode and the screen will stay black. While holding, plug in the USB cable from your phone to your computer. Let volumes go alter plugged in.
Wait some time (should not be longer than ~300 seconds).
Enjoy your brand new device.
FAQ:
Does this work on Mac or on Linux?
Unfortunately no, tool is Windows only. You should need at least Windows 7.
Why is my antivirus freaking out when unzipping the archive or running the tool?
In an effort to protect reverse engineering from being done (and by extension prevent conversion process like it was done on 6T and 7Pro), OnePlus now use VM Protect V3 in their MSM tools. As this tries to detect debug environment, this is seen as malicious behaviour by some antivirus.
My device isn't detected when I click on "Enum" button
Go to device manager and make sure your phone shows up as QDLOADER 9008.
If it shows up as QHUSB_BULK, it means Qualcomm driver wasn't installed automatically by Windows Update. Download the latest one from Microsoft website at http://download.windowsupdate.com/c..._fba473728483260906ba044af3c063e309e6259d.cab (source https://www.catalog.update.microsoft.com/Search.aspx?q=qualcomm hs usb 9008 ) and install it manually by right clicking on QHUSB_BULK and selecting "Update driver software" and "Browse my computer for driver software" to where you downloaded CAB file.
MSM tool is stuck on "Param pre-processing"
Ensure you're using the Qualcomm drivers linked above.
MSM tool is stuck on "Sahara communication failed"
Unplug your phone, get in fastboot mode, turn off phone, wait 15 secondes and get back in Qualcomm EDL mode. You can also try using a USB 2.0 port instead of a 3.0 one.
What is SMT Download mode?
Just don't try to unlock that mode, it will wipe your IMEI and your Widevine certificate if you use it.
How can I fix "SMT config not found" error?
Please refer to https://forum.xda-developers.com/showpost.php?p=83448961&postcount=61, all credits to @Shadow12347 for finding it out.
Why is my device getting in Qualcomm crashdump mode in spite of a successful download?
Your unit was most likely manufactured after March 9th 2021, see https://forum.xda-developers.com/t/...ice-to-oxygenos.4180837/page-14#post-84789741 for reference. You therefore need to use HydrogenOS 11.0.7.12 MSM to recover your device linked at https://www.oneplusbbs.com/thread-5886794-1.html (mirrored at https://mega.nz/file/O8UySbgR#cXGlHkdA_7CYEhKIrek9zzAEwJ7Vx1D5BZdemnPlvGE by @pikatenor ). Getting new OxygenOS MSM tools is nowadays impossible unless you own the device it is meant for, so OP will not be updated to add new OxygenOS MSM tools allowing to workaround this issue. Feel however free to reach out to me in DM if you would like to get told how to maximise your chances to obtain one.

Will this work for the T-Mobile OnePlus 8T+ or only the unlocked version?
If it does work I guess I'll have to wait for my bootloader unlock code from OnePlus before doing this, or will this bypass it? (I'm already SIM unlocked but Everytime I try to request a Bootloader unlock code and press submit it tells me to enter a valid code, OP claims it's because it's not yet 45 days from when I purchased the device, which doesn't make sense)
#3 I don't see the link anywhere where I can download the MSM tool, it says download tool but does give a link
Thanks for your great work

MSM tools don't care about bootloader lock status. So IF, and that's an IF until we hear otherwise, it works with our model, you won't need to be bootloader unlocked before running it.
I personally won't do anything until we also have the T-Mobile MSM tool as well.

Assuming it works, will I be able to go with the version of the MSM tool from TMO to International OS or I'll need to wait for the TMO MSM tool and load the International OS into that MSM tool and get it done that way?

Great job getting hold of these, vouch!

Not sure. It wasn't possible with the 7T Pro because the device name was different (hotdog vs hotdogg). OP would be better able to answer this.

I'd assume it's the same here as well, because recent years were always that the case and I'll be surprised if it's not the case here as well, so I guess I'll wait a bit longer for the T-Mobile MSM Tool

@SmileBigNow you need to open the spoilers to see the download links
Additionally above files are strictly intended for unlocked units and cannot be used for conversion, however I got the file to unbrick T-Mobile variant as well, but I would prefer if someone could confirm it flash on their device before releasing it, feel free to DM me on here or Telegram (link on my profile). Note that I prefer latter.
If it works I will make a separate thread for it.

I have the same issue. OnePlus reps couldn't wrap their head around that I'm already network unlocked... Kept saying I needed to wait the 45 days which is complete horse****. I had my 7t unlocked within a week and bootloader unlocked in 2. I get the same invalid unlock code error. Good God. They even tried to tell me "the unlock code TMO gave you is bad..."

Yeah, it doesn't even make any sense the 45 days wait, the 45 days is usually to get a SIM unlock from T-Mobile not a unlock code from OP, they are just coming up with stupid excuses

IN2020 back to stock

Hey guys, since I just can't seem to find it myself, I'll ask here.
Im currently owning an IN2020 model, which, for the life of me I can't get back up running after rooting it (worked for around 5h, then I got stuck in a bootloop)
Right now, I'm stuck in fastboot/qualcomm crash dump mode, can't progress any further.
When trying to flash any of the International, Indian or Europe Versions of OOS (I tried several different versions, A10 and A11 alike) either I have some modules not working, i.e. WIFI won't turn on, Phone can't register my SIM so I can't make calls etc etc or it just goes straight to qualcomm crash dump mode.
Bootloader is unlocked.
fastboot oem edl nets me a "FAILED (remote: unknown command)", and I tried the "vol+/vol-" trick for over an hour now to no avail, so I cant use MSMTool either.
Can someone please provide me with a link to a working stock ROM for the IN2020 model I can flash via fastboot?
Or maybe theres a solution I just can't see right now, I'm not that great with Android tbh.
Any help is much appreciated, if you need any info/dumps, please also tell me how to get them.

Here are Fastboot roms.

Thanks for the quick reply, but for the MSM unbrick tool, I can't enter Qualcomm EDL mode, neither via fastboot command nor the vol+/vol- plug-in method.
Am I right in thinking that I need a GLOBAL fastboot rom for the IN2020 model to work properly?

Edit:
Seems like having the phone connected via a USB3.0 port was the issue here, I tried a 2.0 and suddenly i can enter EDL. Now running the MSMtool (working fine so far). I'll update as soon as its finished.
Edit 2:
Well, beat me up and call me names, it actually worked, phone is now "set up" again, ill still keep a second alarm on for tonight though, just in case my phone decides to go back to bootloop. All this time all it took was a 2.0-port ...
Thanks anyway, next time I'll be a bit more careful when playing around =)

Progress is good!

hi, I have a bricked IN2020 as you did.
may I know which fastboot rom in the above link you had chosen work for you? As I can see only indian / EU /international build, and cannot find any Chinese hydrogen build for IN2020.
Or it worked fine for you to flash an international into the IN2020? Thanks for advise

OnePlus 8 Pro refuses to install TWRP. Qualcomm Crash Dumps every time. Any advice?

I want to install TWRP as my recovery I've tried at least four different versions that are listed here and a few others from other links:
https://forum.xda-developers.com/t/...p-for-oneplus-8-8-pro-unified-stable.4101313/
I'm not having driver issues anymore so I'm working with adb and fastboot fine. All commands are going through fine and I've tried flashing to recovery_a and recovery_b. Factory resetting doesn't resolve the issue. Every walkthrough I find I get to says flash then boot to TWRP but every time I flash it qualcomm dumps and every time I boot to it it qualcomm dumps.
Is there something corrupted in my recovery I need to wipe somehow? If so how do I wipe it because the only command I found online that would run was fastboot -w and that didn't fix the issue either.
Honestly really annoying at this. This is my 4th OnePlus phone and I've never had so many issues flashing it.
Edit:
I have also tried to do whatever steps are needed to go back to base stock and OS and it doesn't seem to work either. Any help would be appreciated.
Edit 2:
I did it. For anyone who finds this thread in the future the MSM tool did finally work. This is the video I used in the end
(I muted it.) and the first few starts it failed. I went into the properties of the MSM exe and under compatibility checked ran as admin. I also did install the qualcomm driver at some point way before this so not sure if that helped. The MSM tool still didn't work until I started it, turned my phone off, held both volume buttons (not the power) while plugging the phone in. All the stuff online I saw had people starting the program at this point but mine had started already and was in a "waiting for device" state when it worked.
What a lifesaver. Won't be messing around with this again until TWRP is available.

Because you are unable to flash phone's Stock ROM take phone to authorized service center and let them fix it.

Flash stock recovery. TWRP is but compatible with OOS11 for 8/Pro.

I have had so much trouble figuring that out too. Do you have a good link for that? I can't find an easy way to do it. I've seen people recommend the msmdownloadtool but every time I use it it doesn't pick up my phone.
I've settled with Lineage OS and Gapps until I figure out more.

Sorry if I wasn't clear either. I was wondering if you have a good resource for flashing the stock again. I haven't been able to myself.

The same way to flashed TWRP.
fastboot flash recovery recovery_a and _b.
In the future, you should not flash both slots, just flash without specifying _a or _b.

In the future, you should not flash both slots, just flash without specifying _a or _b.

Although i am not sure which OOS version you use, so you might have to change branch

I hate to be this much of a noob about it but I see a recovery file listed in the link you sent. Is that the recovery I flash? And if so after flashing is this branch also a stock rom? I've been trying for a while now just to get back to the basic oxygen that comes with the phone but it's been a nightmare for me and it feels like no resource I find fully explains it.

If you want OOS back / new start, best way is really to use MSM. Haven't really used it, so can't help you much. There are tutorials online / YouTube though

Gotcha. Unfortunately I haven't been able to get MSM to recognize my phone yet but I guess I will keep working on it and see what I can do. Thanks for your help.

It is very sensitive to which USB port you use. For some people only USB2.0 works, for me USB3 works fine as long as it's chipset USB3. The second ASMedia controller doesn't work.
Also, use original cable, and switch off the phone completely, get MSM to the point it's waiting for device so start the download before connecting phone, then while holding the volume keys connect the USB cable and it should instantly start flashing.
