flashing firmware zip fails every time

I am currently using a OnePlus 5 which used to run on a stock based rom, xxxNoLimits v3.1
Since the dev ended the support I wanted to revert back to pure OOS, so I downlaoded the newest 5.1.5 zip and followed the instructions using the newest blu_spark twrp recovery but right after pressing the "flash" button I kept getting error 7, so I download the zip from a mirror link and I have also tried the newest version of codeworkx twrp, still error 7. Then I tried flashing the original stock recovery in order to flash the zip but it instantly threw me back to the zip selection menu, flashing the zip via adb sideload kept quitting at exactly 47%. At this point I was pretty frustrated, I flashed twrp codeworkx again and wiped EVERYTHING, which includes the system, data, cache, dalvik partitions and then I also did a format on the data partition, the point was that now I would have a clean phone only running twrp and I thought I could easily flash the newest zip now without any problems, NOPE, still error 7!!! Now I am stuck here, the stock recovery doesnt let me flash anything and I've tried 4 different versions of twrp recoverys and every single one gives me the same error, I even dug up an older version of OOS, I think it which I had running for a few weeks without any probles so I knew that the zip was not corrupted but same error
Now I had given up and wanted to restore the backup I did just in case anything goes wrong, well, restoring the backup fails when it tries to restore the data partition, so I unchecked everything except system, system image and recovery but it didnt work, now I am sitting here with my phone telling me that there's no OS installed. any advice?

Use Unbrick Tool and Restore
Hey,
You can Flash your Mobile using the Unbrick tool at - https://androidfilehost.com/?w=files&flid=204903
Use the Latest file which I guess comes with OOS 5.1.3 - https://androidfilehost.com/?fid=962339331458999196
If you try to Go to Open Beta ROM First Flash Open Beta 12--> Open Beta 13 --> Open Beta 17

Hi ! Do you have some news about it ? I have the same issue since Monday...
I've tried like anything i've found and even more, but nothing did the job ...
The only way to have my OP5 working is downgrade to an old version running Android 7.1.1

Oneplus 5 hardstuck bootloop. Please help me out, I've tried everything!

Firstly, my phone isn't hard-bricked. I'm able to load different versions of the TWRP recovery and access Fastboot without any problems. I'm also pretty comfortable using adb to push, sideload, access fastboot, recovery , etc. so please feel free to throw out any suggestions that might help me resolve my issue. (Note:I'm unable to find the stock recovery on OnePlus's support page anymore, I recall they always had the option to download the stock recovery just below the download option for the stock ROM, so I haven't been able to try sideloading after formatting with the stock recovery.)
My OnePlus 5 was running stock Oreo and I'd been meaning to upgrade to Lineage 16.0 (Pie) or any other Pie ROM really. I booted into TWRP (3.2.3-0 - Oreo firmware) and wiped everything other than USB storage and formatted data too as my previous Oreo installation was encrypted. Then, I downloaded codeworkxx's 9.0.3 firmware for OnePlus 5 and pushed it to my phone using adb. I flashed the firmware successfully, rebooted into Bootloader/fastboot; and flashed the Android Pie version of TWRP recovery ( https://sourceforge.net/projects/cheeseburgerdumplings/files/16.0/cheeseburger/ ) and was able to successfully boot back into the recovery. Since then, I've tried to flash multiple different Pie ROMs (Pixel Experience, Lineage 16.0, stock OOS official build - 9.0.3 , Beta OOS build OpenBeta26) (clean flashing always) but always ended up with a bootloop with the boot animations in all the ROMs. I've even tried flashing them with Magisk-v18.0 but that doesn't help either. I've waited for 15 min with each boot for the different ROM's (ending up in bootloops) and on rebooting back to TWRP, I've always found that irrespective of ROMs, the only folder that's created in Internal Storage is 'obb' and it is an empty folder. I've even tried sideloading OOS 9.0.3 (official build) via TWRP and that still ends up in a bootloop with the obb folder in Internal Storage being the only thing created. Also, flashing the boot.img recovery in the stock ROM zip files leads to a blank screen with a white LED that tries to install Qualcom drivers, so I just reflashed TWRP and am back to where I started.
That pretty much sums up my problem here. Kindly throw suggestions at me to help fix my problem' I've searched the forums but most of the bootloop issues I've found and read are about unsuccessful firmware flashes (not the case with me as I've explained above) or dirty flashes (again, not the case with me as I always cleanflash).
Thanks!

You should be focusing on getting stock OOS back on before trying custom rom. Have you tried rolling back to 5.1.7 Oreo? Sometime it better to go back to square 1 and try again.

I successfully flashed the 5.1.7 firmware and Oreo-TWRP-recovery and was able to install Lineage OS 15.1 and boot it up properly. I'm unable to find a link for previous versions of OOS to test whether or not 5.1.7 would work. Do you know where I can find a link?
Thanks again!

So the Lineage 15.1 flash worked fine but OOS 5.1.7 still leaves me with a bootloop and the obb folder as detailed in my first post. I'm unsure as to how to proceed.

Can you please try to flash 5.1.4 stock oxygenOS rom and the 5.1.7 after it, then magisk and reboot to the os?
Make sure you have an old Oreo compatible recovery like this https://drive.google.com/file/d/1DrEMydZfQxC_eWx1W-OlASo8H7okXNTQ/view?usp=drivesdk

Lineage 15.1 (official) boots successfully but without radios working... I tried reflashing Firmware-5.1.7 but that does not help; not sure how to fix this. Could it be a firmware issue with installing Pie ROMs? But then again, OOS Oreo doesn't boot either - still ends up in a bootloop

My only suggestion ...

Greetings! I got your private message, but I haven't read it yet. Sorry, very busy today. However, I can make the following suggestion to get your device back into original working order.
Have a look at this link on xda. It's for an unbrick tool, which I've used numerous times with great success.
https://forum.xda-developers.com/oneplus-5/how-to/unbrick-tool-oneplus-5-t3648169
This tool will put your device back into its original condition, with original OOS.
Let me know if it works for you.

Wiping system, data, cache, Installing 5.1.4, then magisk, then format internal storage, then boot os should not cause a bootloop
What's your twrp recovery? Did you tried mine?

The tool doesn't detect my device whatsoever - I have system-wide adb & fastboot set up (to use from any folder or path) yet the device is not detected in fastboot mode or recovery mode.
How do you use it?
Thanks!

You need to put your device into MSM Download mode. It's simple. Power off your device. Press and hold the Volume UP key for about 8-10 seconds and, while continuing to hold the Volume UP key, plug in your device to your computer via USB. Open the MSM Tool and press Start.
That's it.
It takes about 3-5 minutes for the tool to complete the unbrick process.

Thank you! I was able to successfully use the unbrick tool to reset to OOS 4.5.8 Nougat. I'm going to try stepping all the way up to Pie now!

What's the REAL method to successfully install a working TWRP, root and custom ROM?

Hi All, I have been reading various threads here and searching on Google for finding a method that truly works for successfully installing a custom ROM, getting TWRP installed and rooting with Magisk. So far, all I have found are numerous and usually contradictory methods and about 7 or 8 different versions of TWRP (so which one is completely stable and working properly?). I have tried several methods over the past two weeks and none of them are working completely.
Sometimes, I'll get a version of TWRP installed, but then trying to reboot to recovery results in a "system has been destroyed" image. Or I'll succeed in getting a custom ROM installed, but Gapps will fail with error 20 or error 70 or there's not enough space on the system partition (and I'm just trying to install the Pico version). Even I double check that the Gapps version matches the ROM version I've used, but still get an error 20 displayed.
From what I had read on numerous threads, it seemed like CosmicDans TWRP would be the one I should go with. I downloaded both of his files (the fastboot image and the zipped installer) and fastboot his "boot-recovery.img" that was specifically for fastboot only and from that recovery, I installed his "TWRP-Installer-3.2.1-with-Tissot-Manager-2.5.zip". Everything appeared as if successfully installed as per the logs, but immediately upon attempting to reboot to recovery, I get the "system has been destroyed" image.
What I want to do is:
Get a working custom ROM (preferably Pie) installed
Install Gapps
Install a working TWRP (that will not display "system has been destroyed" whenever trying to boot to recovery)
Finally, install Magisk and root my phone
Can anyone suggest a site or link or a post somewhere that would explain everything correctly and is actually working? This has been a very frustrating experience. I'm almost sorry that I even bought the Mi A1. Never had any problems installing custom ROMs or rooting the OnePlus devices. All I'm left with currently is an expensive paperweight.
Thanks so much!
Cheers

From your description, I'm certain that you do this on a Pie stock rom right? the installer never work on Pie stock and will cause system destroy. Just hotboot TWRP. And for the Gapps, I think it's due to the time you install it. From my experience, install Gapps after rom and before Magisk usually work. Install after magisk or custom kernel will somehow cause the same issue that you described.
Oh, in case you want to install LineageOS, you have to come to the LOS16 thread and download the TWRP from there, it's the only TWRP that can install LOS16.

Thank you for your reply. When I first started the process to change to a custom ROM, I was on stock Pie. But one of the times I was wiping the device after one more problem, I accidentally also wiped Internal Storage as well. I didn't have much there since I had already backed some things up in advance. Now it's virtually empty. The steps I take are:
1. Hotboot TWRP
2. Install Custom ROM
3. Hotboot TWRP again
4. Install Gapps
This is where I usually have some problem. It's the process of installing Gapps that creates some error.
I also did attempt to install LineageOS 16 using the TWRP recovery that was linked in the post. Follow the instructions precisely I believe and now when it's time to install Gapps, I get error 64. I can't understand why. I am attempting to install "open_gapps-arm64-9.0-nano". This should be compatible with the Mi A1 with LineageOS 16 from what I am able to tell.
No matter what TWRP version I use, no matter what custom ROM I try, no matter what steps I take, there is always some issue that prevents me from completing any installation. But the abundance of so many conflicting posts don't help either. One post will state to use a specific TWRP and certain steps; another post will suggest completely different steps using another TWRP; and yet another post will provide different steps still. In some instances, there will be steps listed in the script on the phone regarding the next steps after the ROM installation that are completely different then the steps provided in the post for that ROM in the forum.
It would just be tremendously helpful to get some instructions that actually do work. As of now, I'm about ready to dump this phone in the trash bin. It's horrible. I can't even tell if it might be decent eventually since I never can get anything installed.
Thanks again for your reply Never_Sm1le.
Cheers.

There is no permanent TWRP install for android 9 on MiA1 as far as i know.
Hotboot works just perfect.

Your reply makes me want to stay on LOS 15.1 even more. So many weird problems happen in LOS 16

I followed all the instructions of Resurrection Remix and TWRP is installed and magisk works perfect.

Hello friend, I am currently on Lineage OS 16.0 with Magisk, Opengapps and TWRP installed. I can boot to recovery with no problems at all; in fact, I used the flashed TWRP to install Magisk.
Here are the steps I took:
Download the TWRP boot img and TWRP installer by CosmicDan (Link below)
Copy the custom rom ZIP, TWRP installer, Magisk installer and Gapps into your SD card
Reboot your device to bootloader
Boot into TWRP using
Code:
fastboot boot boot-recovery.img
do NOT flash via fastboot
Go to Wipe>Advanced Wipe and wipe System, Dalvik, Data, Internal Storage
Press the home button and proceed to flashing the custom rom ZIP
After flashing, reboot to BOOTLOADER then do step 4 again
Flash Gapps, TWRP Installer, then Magisk Installer. You should flash TWRP first before Magisk
Reboot to system and you're good to go
Note that if you are installing Lineage OS and wish to receive nightly OTA updates, having an installed TWRP as your recovery might result in a bootloop after updating. Also, if you want to manually flash the nightly update, you need to boot to the TWRP variant of @flex1911 as flashing lineage using other TWRP will result in an error. I suggest not installing TWRP when using Lineage OS.
(Source: [ROM][OFFICIAL] LineageOS 16.0 for Xiaomi Mi A1)
Regarding your problem with flashing, try to check which slot you are currently in by going to TWRP>Reboot. Keep in mind that when you install a rom, it will always be installed to the inactive slot. For example if you are in slot A, your rom will be installed in slot B. After rebooting, your current active slot will be where the rom is installed. When installing Gapps or any addons, check the slot first. However, when flashing TWRP installer, it will patch both boot_a and boot_b and this is the reason why you need to install twrp first before magisk as TWRP also modifies the boot image.

Bootable TWRP
TWRP Installer
(Both files by @CosmicDan)
Cheers mate!

Thanks for the lengthy reply. However, those steps do not work as you have described. Since, if I wipe Internal Storage (as per your step 5), I just deleted all the files I copied previously in Step 2. What I did, was wipe everything, *then* copied all the files and tried to install. As soon as it try to install Gapps, I get Error 64 again. I am absolutely using "open_gapps-arm64-9.0-nano" and it always fails. I have attempted 11 or 12 times already, using different slots, using different dates of "open_gapps-arm64-9.0-nano" and ALWAYS Error 64. I don't know any other version of Gapps I should be trying. The arm64 versions never will work for me.
I give up. I'll just have to stick with stock ROM. No custom ROMs will work for me no matter which one I use or which version of TWRP I use. I already wasted too much of my life with this garbage phone.

Hi,
Which version of TWRP did you use? There's too many. I don't know which one is considered to be the right one.

Copy the files to your external SD card not internal storage. But if you don't have an ext SD card, don't wipe internal storage.
Also try to check if system is properly mounted when installing gapps.
May I ask what custom rom you are trying to install?
I suggest you try Pixel Experience as it already has a builtin Gapps so you dont have to flash opengapps.

flashing 10.3

Hey guys
I made a post and got no replies but have been looking into it more and remember I need adb to flash the 10.3 update, I've got all the files ready but from reading I'm confused as to how to flash via adb.
I've read you need the phone in twrp while doing flashing you need to flash the other slot blah blah blah , doesn't make sense to me...
Can anyone help me out? I've seen stuff has changed since the 10 update and I'm at a loss right now..
Thanks for any help in advance

You nearly never need adb to update.... Dable in some circumstances with fastboot.
Just...update. You don't specify what OS you run now, rooted , twrp etc...
Read my thread about OOS stable in Guide News section and ask there if it's not clear

You're seriously late in versions of TWRP and Magisk. Update twrp with latest installer.
Then in twrp flash OOS, then twrp installer again
Reboot to recovery to switch slots
Flash again OOS and TWRP installer again
Reboot to twrp and flash Magisk then reboot system
If there's issues with encryption in recovery you can eventually use an OTG disk if you have one or ADB sideload
Last possibility is fastbooting oos ROM

You're seriously late in versions of TWRP and Magisk. Update twrp with latest installer.
Then in twrp flash OOS, then twrp installer again
Reboot to recovery to switch slots
Flash again OOS and TWRP installer again
Reboot to twrp and flash Magisk then reboot system

Brilliant thanks! I've updated twrp and magisk now, had no internet so couldn't update. Do I not need to wipe the internal storage at all when flashing stock oos ontop of havoc?
And for the slot just so I know for certain;
I flash slot A with oos, twrp.
Now I reboot go to slot B, do the exact same.
Reboot again, flash new ROM , twrp/magisk.
Profit? I read you post detailing the slots, that's the part that confuses me. I'm going to have another read so I fully understand what I am actually doing instead of doing everything blind.

Anytime you go from AOSP to OOS, or back you generally have to wipe DATA. If you don't OOS will dump you off at recovery, wipe data and then it will boot generally.
As for the slots, when flashing a ROM it always flashes to the opposite slot. So if you are currently on Slot A and you flash a ROM, it will flash to Slot B. The ROM will also overwrite install it's own recovery. So you install TWRP again if you want. Then you reboot to recovery, it will automatically switch to the new slot since you installed a new ROM. Now on the slot where the new ROM is installed, we could install Magisk or Gapps, things like that if needed. If we wanted to update the original slot (A) we would install the ROM again. As well as TWRP again. Reboot to recovery again, Magisk, etc.
ROMs install to opposite slots. After a ROM installation, rebooting to recovery will switch slots for you. Most other items install to the current slot (that is why you need to reboot before install things like Magisk, Gapps, etc). Hopefully that helps clarify things? If not ask.

That does clear up things for me, I've either mis-read or not read that when on slot A you are actually flashing slot B and Visa versa.
I'll be flashing both my slots to 10.3.1 just so they're fully updated. ( A is my main)
Finally part from me, when I'm going to flash my custom ROM (havoc again) I've just got to repeat said steps but flashing havoc instead of OOS then on the last reboot, recovery and magisk?

Fair warning, I don't use Havoc. I use Lineage, here is how I install AOSP ROMs, (link) However, yes, on the final reboot would be when you install Magisk (Gapps as well if you need them). In theory recovery should already be installed, but installing it again won't hurt anything (installing recovery wipes out Magisk, so install Magisk after recovery if you do that). Remember you need Havoc on both slots (you don't want OOS on one and Havoc on another). So flash it twice.

Great stuff. Thought I understood from how you explained it. I'll check that guide as well and have it to hand just incase.

Something didnt want to play when I was flashing... Got to flashing gapps and magisk, gapps flash gave me a error 64 and i got magisk installed, booted, now I've got no twrp and when I use fastboot it just softbricks then restarts after about 5 minutes, I'm gonna try booting from 3.2.3-2 as that was fine and hope I can boot into recovery and just go lineage I think for something new
EDIT
So I used fastboot --set-active=a, managed to get back to twrp so now its flashed on both again. In the process of flashing lineage now, hopefully this wont chuck another error at me for gapps

Flash a Custom Rom in 2020?

For the past 24+ hours I've been trying to flash a few custom roms on my UNLOCKED BOOTLOADER OP6T, but the phone TURNS OFF a few seconds after the boot sequence/animation.
I've read about the A/B slots and tried the Roms' flashing instructions, along with a few suggestions from others, but I cannot get any Custom Rom on my phone...
Here are the steps I've taken to flash (a few times I tried different things that I'll put in parenthesis). Is there anything ya'll see that I'm doing wrong?:
Starting from OOS 10.3.2 Fastboot Recovery and all required files on an OTG USB Drive
fastboot to TWRP....img
Confirmed I'm on Slot A
Wipe Data/Dalvik
Install OOS...zip (10.3.2)
Install TWRP...zip (3.3.1.32)
Reboot Recovery
(Format Data)
Confirmed I'm on Slot B
Install OOS...zip (10.3.2)
Install TWRP...zip (3.3.1.32)
Reboot Recovery
Confirmed I'm on Slot A
Install Xtended (v8 4/13)
(Wipe Data/Cache)
Install TWRP...zip (3.3.1.32)
Reboot Recovery
Confirmed I'm on Slot B
Install Xtended (v8 4/13)
(Wipe Data/Cache)
Install TWRP...zip (3.3.1.32)
Reboot Recovery
Confirmed I'm on Slot A
Install GAPPS (Arm64 10.0 Nano)
(Format Data)
Reboot System

My Guide for Lineage, however it will work for most AOSP based ROMs.
I assume you arent manually switching slots. Don't, there is no need, in fact dont worry about it. Slots will switch automatically after flashing a ROM when you reboot recovery. There is no cache partition, stop wiping this, its not doing anything. There are two slots, but only one data partition that is shared, there isnt a reason to keep wiping it.
On most instructions adding or removing steps will make things not work. Unfortunately for this device there is a lot of out dated information and information that just doesnt work. My guide has been tested with 10.3.3, and the latest version of LOS, however if you have a T-Mobile 6T you are on your own. (I have a regular 6T)

Thanks for the comment! I just followed your guide, but still seeing the boot animation for a few seconds, then the phone vibrates and turns off.
For kicks, I decided to Format Data and I see the boot animation longer, all the way to the end when it's about to start Android, but then it vibrates and shuts off. Strange.
I'm thinking there is something different about my phone... It's a global, unlocked version and I've rooted/flashed hundreds of roms over the years on various devices, so all of this should be a piece of cake................. Thanks!

Have you tried without Gapps?

After the shutdown go back to twrp and extract the content of /sys/fs/pstore/* and upload the files here.

Thanks. I actually gave up and setup stock OOS again, so it took a while to get a TWRP backup, etc. etc.
So after the backup, I installed Xtended + TWRP, reboot to recovery, installed Xtended + TWRP, wiped dalvik, and reboot to system.
Boot animation shut down issue as usual.
Afterwards, I copied the pstore folder (attached zip).
Thanks!

Anything in the logs I can look for?
This is driving me crazy. I flashed MIUI just fine (because it had the .bat file that does everything for you). Essentially it's doing the same thing as flashing OOS & Rom on A/B, right?
Just tried flashing the newest Xtended Rom (May 11th), same issue. Phone vibrates and completely turns off while the boot animation is running.

If you have a TMobile 6t I can confirm I have had to manually change the slots during the flashing process to get custom ROMs installed.

I found out that I do have the T-Mobile version that the seller flashed to International Software haha
When I reboot to recovery, I do see that the slots are being changed though.
Would you mind post the exact steps you took to successfully flash a ROM/GAPPS?
