Cannot install 4.0.2 update

I was using 4.0.0 stock with twrp and root. Tried to install the 4.0.2 update but every boot just took me back to recovery. Tried wiping clean, no change. Tried installing stock recovery v2.0, recovery would hang. Tried using new twrp 3.0.3 and I could get back in, but any ROM, stock or not I installed, would not stick.. Even twrp would warn me "no os installed. reboot anyway?" even when I had just installed a ROM. So in the end I flashed OOS 3.2.8 with twrp and then flashed stock recovery. At this point I'm pretty much at factory stock at v3.2.8 with stock recovery v1.0. Now I'm trying to update to 4.0.2 via OTA and for the 3rd time already I have received a installation failed message and rebooted to system. The first time I thought it was because I disconnected VPN after starting the download, so I downloaded a second and a third time. I don't want to resort to sideloading again because I fear I might get the same no OS installed problem I got when I tried to install 4.0.2 in the first place. Does anyone have any insight on what is wrong?

Steps:
1. Install latest Official or Modified TWRP ( 3.0.3/ 3.0.3 version 14 by eng.stk)
2. Enter into recovery. Connect phone to PC and copy downloaded ROM file.
3. Wipe everything in the recovery- Data, System, cache and Dalvic. It will erase everything.
4. Flash ROM zip after completing, don't reboot phone. Reboot to recovery again, and then reboot phone.
If u reboot phone directly after flashing ROM, u will loose TWRP.

Even twrp would warn me "no os installed. reboot anyway?" even when I had just installed a ROM.

This is pretty normal for nougat OOS. I've faced it for all 3 ROMs i flashed. Don't worry, your ROM was flashed successfully. You can mount and check the /system partition, you can see your ROM files there.
So here's what worked for me. (considering you are on ext4 /data)
1. Flash latest official twrp recovert ext4 version or use the file system swapper zip if it doesn't decrypt your data in recovery. TWRP has some issues as of now and mounts f2fs as default, so you just need to flash the file system swapper zip in order to swap it to ext4 by default.
2. Wipe /system /cache and dalvik cache.
3. Flash full 4.0.2 ROM zip, should be 1.4 GB in size.
4. Flash TWRP image again just in case.
5. Reboot to recovery, not to system.
6. Flash stable 2.79 Super Su and you are good to go.

Thanks for the tip, however I don't mind losing twrp, I only want to get stock unaltered update and this procedure does not help in this

Have you tried this guide: https://forum.xda-developers.com/oneplus-3/how-to/guide-flashing-oos-v4-0-1-custom-rom-t3537757
P.S. I think you did, but I'm just asking.

Thanks for the tip, but I fixed it. Ended up flashing v3.2.8 via twrp and installed OTA to 4.0.1 via sideload. Recovery would not boot unless first fully booted into the system. After that sideloaded 4.0.2 via OTA and now back to complete stock.
Thanks guys!

TWRP Can't Decrypt

I haven't had any software update for about 1.5 months. I was on Resurrect Remix ROM Nougat, firmware 3.2.6, and on TWRP 3.0.1 (or 3.0.0 I'm not too sure). Today I tried updating. Things went wrong. Here are my steps:
1. Wiped everything except internal storage.
2. Updated recovery to twrp-3.0.2-1.28 within recovery itself. Used the file given on the ROM thread https://forum.xda-developers.com/oneplus-3/development/rom-resurrection-remix-m-t3399960?nocache=1.
3. TWRP couldn't decrypt my phone even with the right password.
4. Downgraded TWRP back to 3.0.1. Decryption worked.
5. Updated firmware & modem to version 4 within recovery. Used the files given on the same ROM thread.
6. Updated recovery again to twrp-3.0.2-1.28, this time via fastboot.
7. TWRP couldn't decrypt. Tried trwp 3.0.3 from the official twrp site as well. Same problem.
8. Downgraded TWRP back to 3.0.1. Recovery didn't even start. Phone freezes.
I have two questions. What is causing this problem? And second, any way I can use fastboot to downgrade firmware 3.2.6, so that I can at least access my internal storage and back it up. I got loads of data in there.

Hi I made that too with this rom! (https://forum.xda-developers.com/oneplus-3/development/rom-resurrection-remix-5-8-0-oms-t3527344) I think it is that 3.0.3 TWRP that did it! I hawe to wipe everything but i got it working! with these instruction https://forums.oneplus.net/threads/guide-mega-unbrick-guide-for-a-hard-bricked-oneplus-3.452634/ Method 2 worked for me but it wipes all! there seemed to be instructions for not loosing all but i cant test it

I have found a solution. Even without decrypting /data, you can still get into recovery (except you can't read your data partition). This is key. What I did is simply use recovery sideload to flash the old 3.2.6 firmware (apparently flashing works even without decryption), use fastboot to flash twrp 3.0.1, and backup all my data to the computer via mtp. Then I completely wiped everything, flashed the new firmware and recovery, and decryption worked.

I cannot install xiaomi.eu. ERROR 7 in TWRP

I can't install xiaomi.eu for my mi5s. When I try to install I get error
Updater process ended with ERROR: 7
Error installing zip file '/sdcard/xiaomi.eu_multi_MI5S_V8.5.2.0.MAGCNED_v8-6.0.zip'
md5 for this file is ok

Are you using Updater app?
You should not!
Use TWRP.
BTW, your device is unlocked, isn't it?

Error 7 is that the ROM is not for your phone.

bootloader version problem
You might have installed TWRP and tried to install EU rom.
Flash the latest chinese developer rom to update the bootloader, wipe and install the EU rom you want.
It'll solve the problem

Questions about upgrading 5T from 5.1.1 to 5.1.3

Hey. I have a rooted with TWRP installed OnePlus 5T on OOS v5.1.1
I've been receiving the 5.1.3 upgrade for a while now and have decided to update. Can i dirty flash the package or do i need to wipe system and data? I'm guessing the root will not be retained and i will have to root again but will the TWRP recovery stay intact? Thanks for your answers

I guess you would be able dirty flash.
You have to flash the twrp and magisk root again. If you are going to flash latest Open Beta 11, you have to flash Beta 10 before to retain data.

I have switched from 5.1.3 to beta11 like;
1- download the rom you want to install from oneplus site.
2- also download the stock recovery image from oneplus site.
3- put both files into the phone.
4- flash the stock recovery you downloaded.
5- boot into stock recovery and install the downloaded rom without wiping or formating anything.
6- enjoy your new rom with all your apps and data.
After the above steps you can install custom recovery and magisk again.
I also highly recommend to take a full backup of your phone .

Why was stock recovery flashed? Can the Rom not be installed using TWRP?

Well, i always got an error with twrp. No OS installed or something like that. Tried also a dirty flash with twrp and phone was not able to boot. So i found the way with stock recovery.

Rom can be flashed with Blu Spark treble TWRP V8.78not normal TWRP. And after you flash reboot to recovery then flash magisk 15.3 and no verity V2 or version 3 if your not encrypted either work, I used V2 just fine.
If you try to flash magisk right after rom it will probably give you an error. Reboot only to recovery BEFORE letting the rom boot or you loose recovery, then magisk will flash, 15.3 is the least grievous version after a successful boot upgrading to 16.4 is easy.
16.6 has been giving people grief also.

Impossible to install custom rom with TWRP

Hi, earlier, I wanted to change the rom of my mi 5s. I've got an error 7 on twrp during the flash. I tried many things: edit the installation script, format all the data, update and downgrade TWRP, and finally perform a fastboot flash using mi flash and the last one worked. But I am not longer able to flash a custom rom without getting error 7 after the "Patching system image unconditionally" message. I've tested lineage, havoc, pixel experience, miui, even 8.1 rom but same result. I'm stuck with fastboot global miui 10
Btw, I think that after the error the partition are corrupted since I can't repair them with TWRP.
I don't know what I can do more.
edit: I tried to lock and relock bootlander, still geting the same error. I'm stuck on Oreo

I think that i figured out something, I am able to flash system.img file using fastboot but I can't flash zip rom using recovery.
As anyone encounter this ?

Did you try reflash twrp latest version?
