Yeah, it is pretty off topic. But basically, F2FS is supposed to be faster opening apps. But probably only noticeable in more intensive games. Most other apps, the difference is reported by folks to be insignificant. You can read some more arguments pro and con on the following threads:

https://xdaforums.com/oneplus-3t/help/insainly-slow-partition-update-twrp-t3656276

https://xdaforums.com/oneplus-3t/help/twrp-super-slow-loading-twrp-t3663815

As well as a good technical write up comparing F2FS versus EXT4 here:

https://www.xda-developers.com/clea...-and-op3t-storage-speed-differences-and-f2fs/

There are some concerns that F2FS is not quite mature enough, and may lead to data instability. Which is supposedly the reason why OP went back to EXT4 for the OnePlus 5:

https://forums.oneplus.net/threads/ext4-on-oneplus-5-no-f2fs-why.554647/

Personally, I always backup my data to the cloud, and also to PC (and everyone should backup their data some way, if it's important to them). So I'm not terribly concerned about losing data.

TWRP boot is also much slower on F2FS. Obviously not an issue if you are on stock recovery/stock phone. And unless you are booting to TWRP frequently (such as a ROM flashing fanatic - and that's completely valid) I don't see this as a deal breaker in itself. But as you can see from the threads linked, it really bothers some folks. Not sure if they fixed or worked around the issue in the newer versions of TWRP. But I just updated to TWRP 3.1.1-2 and the boot times seem much quicker. It takes 1-2 minutes to boot TWRP now, and before it took more like 4-5 minutes. Supposedly, this is dependent on how much data on the data partition. But if anything, I have

more

data there now.

I have read it, but I just wanted to reconfirm because my friend said it is possible to brick a phone without unrooting the phone while flashing the updated ROM.
[OnePlus 3T Guides, News, & Discussion] ZenR2:
Thanking you so much for cleaning out the doubts :)

Yup, don't need to unroot before you flash

So guys, I'm on OOS 4.1.7, rooted with SuperSU and on TWRP. I have decrypted my device... So my question is, what steps should I follow to update to the latest 4.5.0 version? As, flashing OOS zip would overwrite the TWRP with OOS Recovery & also encrypt my device, which I don't want to happen...coz then I would've to move all my 30 gigs+ of data to my PC & again put it back :/

TIA! :)
[OnePlus 3T Guides, News, & Discussion] mmurphmsu:
Did you even read the third post? It tells you the exact steps to perform.
[OnePlus 3T Guides, News, & Discussion] redpoint73:
You will only soft brick if you mistakenly flash the OTA (partial or "patch") update instead of the full update zip. The "soft" brick is recoverable, simply by flashing the full update zip. This is all described clearly in the instructions in Post #3.

This device is actually pretty difficult to truly brick (some call that a "hard brick). And you aren't going to do so, by following the instructions posted here by Funk_Wizard, Midomad, etc.

Unless you friend is specifically knowledgeable about the OnePlus 3T; he should refrain from giving advice, with the assumption that all Android phones are the same. Each device has a lot of subtle nuances, and drastically different rules/processes about updating, root, etc.
[OnePlus 3T Guides, News, & Discussion] DarkSJ1998:
Yes I read it. But it doesn't say anything regarding the encryption thing. I don't want my device to encrypt again automatically
[OnePlus 3T Guides, News, & Discussion] redpoint73:
No problem, you're quite welcome.

What I also meant to post, and forgot: It's mostly a matter of your preference and how you use your device, whether to stay on F2FS or convert it to EXT4.

---------- Post added at 10:54 AM ---------- Previous post was at 10:50 AM ----------

I'm not too up on the subject, but flashing the patched boot image would be one way to prevent forced encryption (may be other methods):

https://xdaforums.com/oneplus-3t/how-to/rom-dm-verity-force-encryption-disabled-t3618232

I'd still recommend to backup any data, that is important to you; before doing a big update like this. Just in case.

---------- Post added at 10:58 AM ---------- Previous post was at 10:54 AM ----------

Have the SuperSU zip (or Magisk zip, if preferred) on the phone when you update. Root immediately (by flashing root zip) after you flash the full 4.5.0 update zip (do not reboot) and this prevent TWRP from being overwritten with stock recovery.

In other words, it will only revert back to stock recovery, if you reboot after updating (before rooting).
[OnePlus 3T Guides, News, & Discussion] RASTAVIPER:
I am pretty sure that I had rebooted my device after upgrading, without rerooting and my custom recovery wasn't affected.

Then I had another reboot and flashed Magisk normally.

So, I don't think that this point is valid.

[OnePlus 3T Guides, News, & Discussion] Sam Nakamura:
Not sure what you did exactly but you can try it yourself, flash full stock OOS and reboot, next time you boot to recovery it's stock and TWRP is gone...

Already happened back in the days with my OnePlus2 :)

I personally don't reboot before I flashed the TWRP image from within TWRP, haven't tried the "root solution yet...

Method to get OxygenOS 4.5 update immediately

Dear All,

Here's a 100% working method to get the latest OxygenOS 4.5 update on your OnePlus 3/3T. You'll get the update in seconds. I have rooted OnePlus 3T with TWRP and this method worked for me and it should work on non-rooted or stock recovery OnePlus 3/3T.

Method:

1. Install VPN Master from PlayStore. Link: https(colon)//play(dot)google(dot)com/store/apps/details?id=com(dot)mdu(dot)mastervpn(dot)free

*Change (dot) to . and (colon) to : in the above link.

2. Open VPN Master and connect to Canada VPN.

3. Go to Settings -> System Updates in your phone.

4. Tap on Check for Updates.

5. You'll get OxygenOS 4.5 update immediately.

6. Start downloading the update and Disconnect VPN and continue the download.

Don't forget to turn VPN off after starting the download.

4.1.6 it worked a little better, I could have more ins and outs of WiFi, and have LTE. But in the end I always ended with stale connection, and no internet.

4.5.0 is like 4.1.7.

What I discovered until now: "disconnecting" and "reconnecting" to the provider network fixes the issue (methods: disable/enable SIM2; change data to SIM1, then to SIM2; Initiate a call on SIM2), then I have roaming LTE.

Next step: switch SIM2 with my wife, as her roaming data works fine.

If u have unlocked bootloader just put ur phone into fastboot mode connect it to ur computer and use adb method to flash twrp. Its simple and easy and no data loss
[OnePlus 3T Guides, News, & Discussion] AndreiVolk:
You only lose data if you unlock the bootloader but i dont think this is your case. Flashing oos replaces twrp with stock recovery but doesn't lock your bootloader. So if for some reason you still have twrp just boot into it and flash magisk. If you have the stock recovery then you need to flash twrp from fastboot then reboot in twrp and flash magisk.

If you have been having GPS problems on two different Android phones my guess is you will have problems on any other Android phone. Enjoy the iPhone ?
[OnePlus 3T Guides, News, & Discussion] nokkenas:
I had a Galaxy Mini, a crappy phone way back on 2010 and GPS works fine (it was on Android 2.3). Nexus 4's GPS was also working fine. Those two phones never gave me any GPS trouble.

My GPS trouble started since I've been using OnePlus One. Brand new it was fine, but some CM/OOS builds crapped the GPS. My experience with Oneplus 3T is also more or less the same with OnePlus One. On some OOS version, GPS works fine, some don't.

I had a friend selling his iPhone 6 since he just got OnePlus 5. So if there's no Android phones LG/Google Pixel/Samsung has good GPS, I'll sadly convert.

To avoid this getting off topic, I won't reply non OOS related posts anymore. Wish me luck guys.
[OnePlus 3T Guides, News, & Discussion] jd1001:
Just out of interest have you ever updated your modem? Again a little off topic but I used to have GPS issues in the past sometimes when I would use CM/non stock ROMs. Never with oneplus but other flagships and my issues were always solved by updating to the lastest modem firmware. Just a thought, would not like to lose anyone to iOS if it is avoidable.

I haven't used any custom roms on my Oneplus 3T. I am on unlocked & rooted Oxygen OS stable release since the first time I got this phone and my updates are from this thread installed by latest TWRP. Correct me if I am wrong, but I reckon the OOS Full ZIP posted here contains modem so I haven't flashed any modems. Do I have to flash them manually?

On my OnePlus One, I have updated the modem. Basically I was testing out modems until I found one that work for me (it was C7.11 or something).
