Flashing ROM bricks phone?! - OnePlus 3 Questions & Answers

I'm currently running my OP3 on Resurrection Remix 5.7.4 (MM 6.01), the phone has the latest version of TWRP and I've flashed other ROMs in the past without any issue
RR has proven to be quite unstable for me, the system UI keeps crashing, which renders the phone unusable until after a reboot so I wanted to flash Freedom OS as that worked quite well for me previously. When I tried to flash the ROM in TWRP the ROM seemed to flash successfully but when I rebooted, only the boot logo showed and then the screen went black and the phone refused to respond at all for about two hours, after that exactly the same thing happened. I managed to boot into recovery and tried flashing a different ROM but the result was the same every time, the only way to get the phone to work normally was to flash RR again/restore from a Nandroid backup, either way, the result is the same, I'm stuck on an unstable ROM and I don't know why, the last time I flashed these ROMs they worked fine, I followed all of the instructions for flashing said ROMs to the letter, I have the latest version of TWRP, etc, does anyone know what the problem could be?

Have you flashed the latest firmware? If not, I think this is why due to you being on a very old version (6.0.1) and as you are not flashing official OxygenOS you are not getting the newest firmware.
Download and flash the latest firmware here:

Pick the right one for the ROM you are flashing (For Freedom OS installing firmware Open Beta 14 - Firmware + Modem under 7.1.1 should be good.)
Note: After you have flashed the firmware the next time you reboot the phone it will appear to not turn on for a few seconds, this is normal while it updates, don't worry
Let me know if you have any questions

[Help] Upgrading AT&T i747m from CWM/4.4.4 KitKat to TWRP/CM12.1

Hello guys,
It's been a while since the last time I visited the SGS3 section, over a year ago I remember updating the bootloader in order to upgrade/flash to 4.4.4 which went very smooth and was a success. I gave the phone to a sibling who has been very happy with it for the last year and a half. Lately, the phone has been very unstable with the 4.4.4 KitKat ROM, WiFi doesn't turn on, Bluetooth is unstable, Unstable apps/Force closes. I tried a wipe/factory restore and re-flashed the ROM but the problems persisted.
I did a little research and liked what CyanogenMod is doing and since they are actively supporting the phone I decided to flash CM12.1 and the provided Open Google-Apps, CM12.1 flashed successfully but Open Google-apps refused to install, CWM displayed (Section 6) error which upon research it is common with CWM and the solution is to flash TWRP. I booted with CM12.1 in order to install TWRP Manager through the APK and flash TWRP but it force-closed when it searched for the device model. WiFi was working but Bluetooth was still unstable.
I would like to know what would be the best way to proceed in this case, I would like to upgrade the recovery to TWRP and flash CM12.1 or any other stable Lollipop ROM.
Thanks,
Oscar

LG Based roms bootloop. Cyanogen is fine.

As title says when I flash or install a recovered LG based rom the handset gets into a bootloop. Lollipop or MM doesn't matter.
I see the BIOS type of screen for a few seconds then 3 seconds of boot animation and back to BIOS.
Cyanogenmod 13 based roms work just fine.
background: After receiving MM ota update rooted and downgraded to lollipop. Installed a modem file in the process as well.
Then I decided that I don't like it either. FLashed cyanogenmod straightaway.
Then flashed genesys rom which is LG based 6.0.1.
Still no problems.
Installed xposed framework and the bootloops started.
Then I run the xposed uninstall script, wipe everything and install LG MM rom. bootloop again.
Sorry for the long post. Didn't know which detail is relevant so wrote it all
Any help would be much appreciated as I am stuck with cyanogen...
Try to go back to stock with lgup
lgup doesn't recognize the handset when CM is installed.
Anyway finally found a solution after trying every trick in the book. Basically flashing modem, boot and bootloader solved the problem.
Now I need to find a way to flash xposed framework without bricking the phone.

bootloop to another level...help needed

Was running Resurrection Remix 7.1.2 on my G5 before flashing the pixel experience 8.1 rom, after flashing it though, it began rebooting after ever 10 seconds or so when booted into the actual os, since this was happening, I restored a backup of RR which was made before flashing oreo, and after restoring this backup my device began showing the same symptoms as the ones I saw on pixel experience, except the reboots had an interval of about 20 minutes, unlike on oreo with 10s, and since this was still happening I decided to flash a stock firmware XT1677 (my device however, is XT1675), and somehow after flashing this stock firmware it was displaying THE EXACT SAME symptoms I saw on oreo and then on RR nougat, so put simply: after flashing oreo, every single rom including stock was rebooting every 10 seconds (except RR with 20 minutes), so what I did was flash TWRP on stock rom (bootloader still unlocked) and flashed RR with the hopes of atleast having a longer interval of reboots, and now whatever rom I flash wont even get past the boot animation, anyone ever heard this happening before, or better yet, know how to fix this?
Sorry for the long paragraph.

Do I need to downgrade pie firmwre if I were to use oreo android ?

My whyred RN5pro come with global rom miui 10 with android pie I think ?
I unlocked the bootloader and flash PE pie latest version, it required pie firmware, and I flash latest pie firmware from https://xiaomifirmwareupdater.com/firmware/whyred/
After usage for half year, I decided to use oreo rom, there's a few reason.
1. I thought always keep update will make it more stable and safe. But I was wrong, the more I update the PE rom, the more unstable it was. After usage a few days, it will freeze and need reboots, sometimes it slow on animation.
2. I need call recorder, but android pie restrict this function.
3. The latest build now come with wifi drop or something, sometimes my internet access is unavailable while my wifi was working fine.
After that I think a lot whether to use pie or oreo, and which custom rom suits my need ?
After reading and searching, and thinking a lot in these 3 days, I come up with a solution.
1. Because the pie keep get updating, it always got bug and some glitches stuff, and I don't have a lot of time and don't like to keep flashing new custom rom, I decided to use Oreo Custom rom final version instead.
2. After a lot of research I come upon RR, PE, havoc OS, liquid remix, lineageos, and decided on lineageos 15.1 final version as my custom rom.
3. Because I don't need a lot customisation, I think lineage os is the best for me, as I only need privacy guard, network traffic indicator, and stability.
So I changed to lineageos 15.1, here is what I do
1. wipe dalvick cache, data , internal storage
2. flash oreo latest firmware V10.3.1.0.OEIMIXM from xiaomi updater site
3. flash lineage-15.1-20180709-UNOFFICIAL-whyred.zip
4. flash magisk 19.3
5. flash opengapps pico
6. flash lazyflasher no verify opt ( ended up failed / error ) Because I read some user getting bootloop caused by encrypted phone or something, I don't know about this part, so I just flash lazyflasher as the instructions said for uncencrypted phone ( ended up failed / error ) ( I don't know if my phone encrypted or not, so I just flash it as additional file)
7. reboot, after getting in, it shows android encrypting, and reboot again, after a few minutes, I thought it stuck on boot loop, but finally it gets into the welcome screen. I tried reboot a few times to see if it stuck or not, but it was working fine. Tested the rom 24 hours by now, and everything seems to work fine.
What I want to ask is,
1. Does my step on changing from pie custom rom to oreo custom rom correct ?
2. lineage-15.1-20180709-UNOFFICIAL-whyred.zip Is this the final version of oreo lineageos 15.1 whyred custom rom ?
3. Sometimes I saw my sim network bar gone completely, but I can make call and check balance, and in the sim status, it show -100dbm and 99 asu. Is this normal ? Or is it because I flash wrong firmware or something ? Or is it caused by my area unstable tower network so the bar completely gone ?
4. Should I use pie or oreo firmware in this custom rom lineageos 15.1 android 8.1 ? Or it's irrelevant because the firmware is flashed by the lineageos custom rom ?
5. Do I need custom kernel ? And what's the best custom kernel for android oreo ?
Other than that, I am satisfied with everything it offers. Thanks for reading and replying.
1. Yes. I've never flashed lazyflasher though.
2. Yes.
3. If you can call, it's probably just very weak signal and the indicator goes off. Otherwise it's a bug in LOS, I doubt the firmware has anything to do with it (I'm on Oreo too).
4. Oreo.
5. No, but it wont hurt you if you try a couple - just make sure they work in Oreo firmware. I'm on KangarooX R4.4 and getting over 10 hours of SOT.

[Help] Problems flashing any android 10+ roms on my redmi 7 device

Hello XDA people. I'm an enthusiast of flashing and testing android ROMs, but I am kinda rookie using this device.
The problem in question is that I cannot successfully flash any Android 10 and later ROMs on my device, I always face several problems after flashing and booting any ROM, such as the wifi's not working (got the exclamation mark on the icon), audio problems, mobile data increiblely slow, bluetooth and GPS issues, etc etc. I tried to flash official and supported ROMs like lineageos, evolutionx, pyxisos, havoc as well as unofficial roms, but I always get the same problems (the wifi issue is the problem that I want to fix the most)
I tried flashing the original MIUI firmware through recovery and bootloader method, I dirty/clean flashed the roms after and nothing, I also used factory reset, used OrangeFox, TWRP (official and unofficial versions) and I still have the same result. I tried every method I know and it seems I won't have the problem fixed. I don't know if it's that the firmware is not properly flashed, or if I deleted a partition. What can I do?
The device only works using the MIUI original firmare but I don't like it because of the bloatware and the waste of resources. I currently use MMX rom (a modified MIUI rom) in my device right now. It works well but It's currently outdated. I just want to use an AOSP based ROM and having my device updated. Please HELP ME!
