I'm using the xxxNolimits rom 5.1.3. When I try to do the procedure to update the version of the oxygen I can not. I downloaded the rom from the site of oneplus, 5.1.4, I make the flash in the TWRP blu spark latest version and when I reboot the message "no OS installed"
I do not know what to do, my oneplus only recognizes the custom rom if I try to go back to the stock it does not recognize. It's like I'm not flashing anything. MA does not appear any error during the flashing of the stock rom by twrp
Have you wiped data? You can't upgrade from xXx to stock OOS without wiping data. Try wiping data, system, flashing OOS, rebooting and if it starts, reboot back to recovery and flash kernel ?

I've had many roms flashed on my op2 through twrp, but now whenever i try to flash any rom(cm, exodus, aicp etc.) I get error 7. I tried deleting asserts line on "updater-script" but no luck...

Hi, If you already have twrp recovery and you can boot into twrp recovery, then you need to download stock oxygen os 2.2.1 ota.
when you download oxygen os 2.2.1 ota, flash it via twrp recovery, after that wipe factory data reset, then you flash your custom roms later. this will bypass the error 7 and you will have to resume enjoying your custom roms.
Here's what happens, when u totally erases the system, data, and formats everything with twrp recovery, custom roms don't run again, i think they kinda need some basic files from the stock rom to enable them to run. i experienced this myself with aicp and this is how i fixed it. so go on, look for the oxygen 2.2.1 ota.zip, download, flash, then wipe data fastory reset, then you can now have your custom roms flashed and working. again.
Right!! but oos 3.0 official is also working

It's there to protect you from flashing a ROM incompatible with your current bootloader (there's two of them, pre oos3 and oos3 bootloader/fastboot).
So if you want to flash a ROM which is Lollipop (or using Lollipop bootloader like easier versions of Graraks and Seraph08s builds) you will have to restore your phone to oos2.x.x first. Same goes the other way around, and also your recovery system must be compatible with respective bootloader.
This info should be force-feeded to every noob checking in on this forum hoping for an easy swapping of ROMs on this phone, which is not gonna happen because of this.
I officially upgraded to 3.0.2, unlocked and rooted my phone.
It was fine for the first few times I flashed multiple ROMs. But ever since I flashed Exodus, I keep having issues switching to different ROM.
A week ago, I flashed "Switch to OOS3_H2OSMMv7" zip and was able to flash Resurrection Remix, but today when I tried switching to CM13 or PA it gets stuck at flashing the ROM zip. I tried flashing the firmware zip again and flash the ROM, but to no avail. It won't flash any ROMs now, just stuck at recovery while flashing the zip.
I have a working fastboot and recovery mode though, so I'm trying to avoid flashing the entire factory image but that seems to be only option left. Does anyone have any clue as to why this is happening and how I can fix it?
Edit: Resurrection Remix gets installed fine, CM13 and PA still giving me issues.
Edit: I downloaded the latest version of CM13 and it works. Earlier I was using June 30 build which seems to have issues with the new firmware. I'll try out the new PA build to see if it fixes that too.
What error does your recovery gives?
Do you have Data Backup?
Can you access ADB while in Recovery?

It does not show any error as it just looping while installing the zip. I have to force shut down the phone to exit it.
Yes, I have backed up all my data
Yes, I am able to access my phone in both ADB and in fastboot modes.
After flashing Custom ROM, Wipe data, cache, d-cache and then reboot.
If still doesnt work try flashing another custom ROM. You can use adb-sideload to flash another zip in recovery mod.
Phone is Lenovo A6000, not plus. I installed multiple TWRPs, 3.1.0 and 2.9 something.
I even installed CWM, still couldn't boot to the recovery.
Now, I know how to flash with fastboot, and I know how to boot. Booting doesn't work at all, it says "booting" and never finishes.
Flashing says "okay" and I reboot, do a reboot to recovery, and I get put into bootloader/fastboot.
Any help? I just bought the phone today, no one messed with it.
Edit: Nevermind. CWM installed. How do I install TWRP, so it works? Also, forgot to mention that the phone has the latest stock rom, 4.4.4.
Edit#2: While trying to install "TWRP-3.1.0-Lenovo-A6000.img",
I got an error.
"Can't open /tmp/update.zip (bad)"
"Installation aborted."
Edit#3: Same error with multiple TWRP images.
First of all the twrp 3.1.0 is meant for nougat roms. Since you are flashing that recovery on KitKat rom which it won't support. So first try updating phone to stock lollipop. Then flash twrp 2.8. then take a complete backup(most important) and save it on SD card. After that flash any rom you want. If you are flashing marshmallow or nougat rom then after flashing rom flash 3.1.0 twrp.
I have long ago (10 minutes after last edit) fixed the problem already by flashing stock firmware through some weird software, and then started updating to latest lollipop firmware, and then installed TWRP 3.1 and then installed RR android version 7.1.2. But, thank you for trying to help. I hereby ask a moderator to close the thread because the problem was resolved. Thank you.
SOLVED. Mods you can delete this.
Hi, I could really use some help. I have the ZE552KL.
I unlocked the bootloader with the official apk from the asus website. I installed twrp successfully. This a brand new phone, it had Android 7.0 installed. I want to install Lineage 8.1.0. I wiped wiped data, cache, dalvik/art cache and system, then went to flash this stock oreo rom with twrp. I quickly realized that's not how you flash that rom. So now I have no OS and anything I try to install does not work.
I followed this guide trying to flash a stock rom back with the ASUS flash tool. Everytime I try it fails to "request signature from server" ?!?!? I've tried installing Lineage from TWRP but that does not work. I believe I need to come from a stock rom.
I'm thinking I'm having problems because I used the official unlocked bootloader? I tried the unofficial but was getting the permission denied error and I was fed up with it. What can I do to get back to a stock rom?
edit: downloaded firmware fromt he asus website and flashed via sd card.
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
