I've TWRP 2.8.7.0 installed on my OPO 64 GB running rooted CS12.0-YNG1TAS2I3. I found the multirom thread "http://forum.xda-developers.com/oneplus-one/development/mod-multirom-v26-t2835738" and flashed it on my phone just for fun.Two weeks earlier when I tried installing OnePlus provided AOSP stock "https://forums.oneplus.net/threads/rom-official-4-4-4-oneplus-aosp.65482/" it gave some error about rom built for older build and I forget about it. Recently I wiped my "data" , "system" , "cache" and "dalvik" and tried to installing AOSP zip again but it gave me error saying updater binary error. I tried installinging "cm-12.0-YNG1TAS17L-bacon-signed.zip" and "cm-12.0-YNG1TAS2I3-bacon-signed.zip" ,downloaded from official website of course, and got the same error. I went back to multirom thread and installed "MultiROM uninstaller" zip and it worked perfectly fine but when I again tried installinging "cm-12.0-YNG1TAS17L-bacon-signed.zip" and "cm-12.0-YNG1TAS2I3-bacon-signed.zip" still the same error. I Google(d) about it and downloaded and flashed "twrp-2.8.0.1-bacon.img" from "https://dl.twrp.me/bacon/twrp-2.8.0.1-bacon.img" using fastboot flash recovery twrp-2.8.0.1.img and tried installing zip from that recovery,same error. Then I repeated process with twrp-2.8.7.0 and still same error. Incidentally I'd good sense of creating backup before erasing all partitions and TWRP had no problem restoring it and for now my phone is up and running. Any ideas why I might be getting those errors?
I also pulled out boot.img from "cm-12.0-YNG1TAS2I3-bacon-signed.zip" and flashed it through fastboot,still TWRP giving the same error
I just got my OP6 yesterday and am having strange difficulties flashing zips from TWRP, including TWRP itself.
After a bit of exploring the stock device, I wanted to unlock, flash custom recovery, and root with Magisk. This is very familiar turf for me from Nexus devices, but the OP6 is a somewhat different animal, I'm learning. I unlocked without any problem, but couldn't successfully flash TWRP. I got a "zip signature verification failed" message. Redownloading TWRP didn't change anything. So, foolishly, I deselected the zip verification checkbox and installed it that way. This got me booting into TWRP when I was trying to boot to system. And in TWRP's file manager, my /sdcard was looking corrupted, though I think I may have had PIN security set up, so there would have been encryption that caused me some confusion without realizing it at the time. I'm not sure about that, though. In any case, I couldn't boot into the system, which I'd somehow seemed to be corrupt or wiped out. I was stuck at the animation where the red dot has two white ones orbiting it. Again, I've done this countless times on other devices. I'm only a newbie on this one.
So I was soft bricked. I got myself up and running again by following the steps at Stock Fastboot ROMs for OnePlus 6. I hope that was the right version of stock to be working with.
Then, after getting a little further along in setting up the device, I went to flash the xXx NoLimits ROM. Since I couldn't flash TWRP, I booted into it and tried to flash NoLimits. Again, I got the zip signature verification error. Later, I flashed a system image downloaded from the OnePlus site. I did that from within the Settings, not from fastboot/TWRP. Didn't change anything, though.
It turns out that I can't flash any zip file other than Magisk. I get the zip signature verification failure error with everything else, even a zip of OOS. The files are fine. They can't all be bad. I fear that my restoration from the initial TWRP debacle isn't quite right. But I couldn't flash TWRP without the error and that was with the factory installation of OOS on a device that I'd just received before anything else had gone wrong.
I've searched XDA and the internet and see lots of people getting this error over the years. But I'm not finding out anything that makes it clear why I'm having this happen with this device. I'll wipe the device and start over again if I have to, but the problem was there when it was stock.
I've spent hours today researching and experimentating with no progress other than what I've gained from all the reading and futility. If you have any knowledge about this, please share it with me.
I had updated from my oneplus 2 to the oneplus 6. and with great ease was able to unlock,flash android P.
Bad to hear that you are facing such problems, as my switching was error free.
One of the solutions which you could try for the Zip signature verfication:
- Use the correct/latest TWRP (I remember this fixing my issue on my previous device..)
- Try to adb sideload and flash the zip.

I have tried TWRP with both the current 3.2.3.0 and the previous 3.2.3.2, both downloaded from twrp.me. Sideloading failed, too. Same zip signature error.
I may have to wipe the device and start over yet again. I'd blame myself for doing something wrong, which may very well the the case. But the zip signature issue was there before I installed anything with the stock system.

Try this https://www.bouncegeek.com/fix-signature-verification-failed-oneplus-devices/. I don't know if it'll work for your device as this is for one plus 5t but they are similar in this regard. I would also download all files fresh to make sure there is no corruption. Also disable any lock screen security (finger print, Pin, face lock, etc.)
Among the things I've tried were that I had happened to find that article earlier. Some of it, I can't do. Like clearing the cache of System Update. I'm not seeing that listed in the Apps on Oxygen like it may have been on Hydrogen. One thing I did do, though, almost the only thing, before unlocking and rooting, was to let the system update with an OTA from 5.18 to 5.19. So that could have played a role based on the article's premise.
In any case, I can't sideload, I still get the zip signature failure in spite of what the article says. I tried the other approach. I'll try again later.
This is frustrating. I bought this phone in no small part because it can be rooted and there is a dev community for it. But if I can't do with it what others are and what I want, it may not be worth keeping. I wish I knew exactly this failure is occurring. That it's not rare, I get. But maybe there's nothing wrong with the files. Can all these repeated downloads be bad ones? I've tried both transferring from my Mac via ftp and downloading directly from the web to the phone.
Are you using "fastboot boot recovery.img" with out the quotes then installing twrp from that booted version of twrp or just trying to fastboot flash recovery.img?
Only the first will work as we don't have a true recovery partition any more.

Yes, I'm booting into TWRP via that command line. It's not permanent. I tried to flash the TWRP zip, but signature verification failed. That was the first of my various failures. If I can't find a way to get this straight, I may return the phone, or at least try and get them to trade it to me for another.
Is your oem lock checked?

Do you mean is "OEM unlocking" toggled on in Developer Options? If so, yes, it is and has been.
I had the zip verification error as well, this version of TWRP worked for me: 3.2.1-0

Interesting. I didn't try going back that far. I ended up abandoning zip signature verification and am just flashing without it. So far, no problems.
Good evening /hello/hi,
i own moto one power device (Ram: 4gb, Version: 9.0 pie, MODEL: moto one power, qualcomm snapdragon 626) and i was trying to root my device..
i was successfully able to unlock my bootloader without any error, then i installed and flashed twrp.img(latest version) after flashing twrp i was trying to flash the magisk file which initially landed with a pop up msg (FAILED). After trying it several times i tried to sideload it using adb and was then finally successful and tried to reboot my phone. After rebooting the device i was constantly stuck in the bootloop for almost 20 minutes, i tried rebooting it later but was still in bootloop, so i realized the rom is deleted.
NOTE: The mistake i made was not backing up my device thinking everything will be done fine but i was wrong and landed with this problem.
I also tried to fetch STOCK ROM from forum and flash it, but those zip files was not working. Some say's "invalid zip file" and or "signature not matched".
I also tried to fix the signature error by turning off the option for signature verfication from twrp but still was unable to flash.
i am currently using a custom rom to work with it, but the stock rom was really very good and i would just like to use it.
SO IN THE END I MAKE A HUMBLE REQUEST TO PLEASE, CAN SOMEONE PROVIDE ME THE STOCK ROM SO I CAN FLASH IT CAN START MY PHONE.
im trying to flash havoc os and just started the process
i am getting the attached error regarding switching slots.
I have carefully followed all the steps, bootloader is unlocked and TWRP is installed too
please help
Update here when the process fails and I choose reboot from TWRP the phones then boots into a clean install of Andrpid 10 is this normal behavior?
so tried various things like changing the slot from a to b and back
changed how the files were copied and the location too but all failed.
reinstalled TWRP too
tried a different custom rom and got the same error
however when trying to reflash stock Android 10 rom this worked so TWRP works?
This can be closed I found a much older version of twrp on the TWRP site itself and that actually allowed me to to flash the ROM
Sounds like you had a bad download. Like a corrupted zip
Thanks bud but it it didn't matter what zip or what wrong I tried none of them worked in the end I downloaded an old version of TWRP 3. 3.1.0 and that worked 1st time
Please close the thread
Hey,
following happend: I dirty flashed LOS 17.1 february update over december version following the instructions ivan gave. After flashing gapps and magisk I flashed the newest TWRP image.
Everything went well (at least it seamt so) I booted to LOS and set up new fingerprints (had to deleate them before flashing), started first app (spotify) and screen went black and phone restarted. Than I got the the FRP Lock message and wasn't able to boot agian neither to LOS nor to TWRP.
Everything followed is here. Tldr: I wasn't able to reflash Stock Rom with Odin no matter what I tried and got lost bettween download mode and nothing.
However I somehow got Android Recovery working!! This is what I can and cannot do:

Now I'm able to boot to download mode and original recovery but not to system.
This is what Recovery shows:

I can wipe data and cache partition, but not system partition.
I can view the logs, but I'm not sure what they are telling me....
I can view my external SD card, but trying to install ether TWRP, LOS or the stock image aborted with an error Update from external storage is disabled following a reboot to recovery. Any idea how to enable that?
ADB seams to be working. It can find the phone, although there is an message Stopping adbd... on the phone.

adb devices -l shows:
XXXXXXXcf0cd263704 sideload product:heroltexx model:SM_G930F device:herolte transport_id:8
Sideloading the stock image or TWRP results in: Total xfer: 0.00x in console and adb status 1 on phonescreen with phone reboot to recovery.
Any other adb command (except those three getter) has ether no effect or results in an error.
Any further attempt to flash again with Odin results in the same errors like described in my last post.
Any ideas? ADB or external storage seams like a good way. But system partition worries me.

Can anyone help me?
Some time ago I had a Samsung S6 Edge G925I with which I had the same problems and errors as you. After an intense week flashing systems and without getting it to work, I took it to a colleague who has box and other tools to unbrick, unfortunately he discovered that the problem was hardware, more specifically emmc memory problem, I had to resort to changing the plate and problem solved. I would advise you to try all the firmwares that you can from your binary and with old versions of Odin, without opening as administrator, I hope you are lucky; I'll keep thinking if I can think of another solution, regards.
Thanks! I have finally made it. It took my the third day (thanks to covid home office) but I'm now up again with new LOS (but old TWRP).
For the record: My last try was using an older and modified version of Odin (3.13 here) and flashing the newest stock image with extracted PIT file. After 3 minutest it finally booted.
Im not sure if it was the older Odin version (some recommending using v3.14 for devices newer 2018) or the modified Odin version.
