Device is bootlooping can anyone help? - OnePlus 6 Questions & Answers

Hi, i was messing around with my root for a while the other day and basically my phone seemed ok for a day or two then today i tried to open the built in file manager and my phone turned off and will only bootloop into twrp.
i noticed a lot of apps playing up, like Ebay would open and crash instantly and so would lots of other apps.
question is, is there possible fixes you know of? i have lots of data that i need with no backup and its not just files
if i flash my stock rom in TWRP without wiping data would i possibly be able to get access again or does flashing stock automatically wipe the data?
if there is no fix is there anyway i can find out a list of my installed apps via TWRP?
thanks

Flashing stock does not wipe data. First try just installing magisk in twrp and reboot.

HELP

So, I purchased my Samsung Galaxy S (Captivate) last weekend. I had it rooted and everything was fine. Then I got rid of some of the bloatware. I wrote a couple of programs for myself to use, so I needed to enable side-loading. I did that-successfully.
First sign of a problem was when I went to the marketplace and it would not download any single app that I tried. So, I went to restore the phone using the backup I made, but some reason it wasn't there.
Then I decided to revert to factory settings. I did a hard reset, but the problem was still not resolved. Then I found a thread on here about Odin 3. I've been trying to use that all night but the best I've gotten is to the File Analysis step. I've tried at least 10 different times.
I'm trying to get everything back up and running and preferably rooted again so that I can use my Titanium backup to restore all my apps and settings.
I'm at my wits end, and any help would be greatly appreciated.
Thanks.
Factory reset would not solve any problems that may have been caused by deleting core apps. Is your phone rooted and nand unlocked (baseband) or just rooted? Are you running a custom rom? If so you need to reflash the rom after clearing cache and dalvik cache. If you still have the original rom then you can reflash an official samsung firmware using odin, look for your handsets firmware on www.samfirmwares.com
Other than that you could try finding out which apps are needed and using root explorer you may be able to fix the version you have. If the market is your only issue then try clearing data and cache settings/manage apps/market and download manager (two different apps)
How did you root your phone? Did you install a custom ROM yet? What bloatware did you remove, and how did you go about it?
Ok. In the wee hours this morning I finally got Odin to work and now everything works as it should. I switched computers and the program worked right away. Intersting tidbit though, I accidentally left the sim card in during the reflash and I had no ill effects. I'm actually wondering if that helped me.
Thanks tina333.
nenol, I used the one touch root. I have not installed a custom rom and I don't remember exactly which of the programs I uninstalled. I used Titanium backup to both backup my apps and to delete the bloatware.
There are very few system apps that are not needed by the system, titanium only backs up data by default. Be careful what you delete and always research first

Stuck in a bootloop + CWM question

Edit: Solved, see bottom
ROM (D6633_Customized HK_1290-5630_23.4.A.0.546_R6C_HK_SuperSU2.46_XZDR2.8.21-signedv2)
Bit of a dumb move on my part. It all started when my snapchat stopped working, I updated, and then Titanium Backup wouldn't restore the data properly (giving me "parse error"). I was trying to fix that and read online that sometimes this is caused by improper permissions, so I booted into recovery mode, couldn't find the option, but somehow decided "hey, maybe my root permission (?) is wrong slash it's 6am and I just watched a wild 2016 election end" and I hit the button. Now my phone is stuck in a bootloop.
So my question:
1) What exactly does re-root phone do (in CWM), and why would that have messed me up? Is it because I have a pre-rooted rom?
2) I wiped cache and delvik and it doesn't help
3) How do I fix this? I was thinking of loading a SuperSU zip on the SD card from my computer and flashing that, assuming somehow a corrupted root is at fault. I can't seem to get the thing in ADB mode as a side note.
3b) If that seems like a good idea, does it matter what one I use?
4) If I reflash the ROM, it should keep my apps and stuff, ya? I don't actually care if my phone is crippled, I just need it to work long enough to properly back up some media, and mainly get my whatsapp over to my new SIM card. If I can't get in it's forever stuck on my old number which I don't have the SIM for anymore.
Any help would be GREATLY appreciated.
Edit: I don't know how to delete this. Anyways, with other resources I found out that because I used a pre-rooted ROM, there were issues with using CWM to try to do the rooting with its built in functions, softbricking the phone. Reflashing the original pre-rooted ROM worked fine.

TWRP Question - so confused

Hi all.
Hope someone can help me. When I got my Samsung S8+, I quickly installed TWRP and then rooted it with magisk the same day I received it.
After that I removed a LOT of bloatware and installed hundreds of apps and everything was fine for 6 months.
One day it gave me a weird lock error, because I think I accidentally removed the OEM Unlock and the phone went crazy.
I had no phone for a few days but eventually I managed to flash stock rom and phone went back to normal.
I lost root, but I managed to keep all my data.
Now I want to see if I can get root again. However, all the tutorials to get TWRP require that I wipe my phone.
My questions are:
Can I root my phone without wiping all my data? Is there a chance that my bootloader is unlocked already or did flashing stock rom remove that?
If I have to wipe my data, how can I keep all my apps (and the app data). I have Titan Backup but that needs root to work so I don't see how to save the app data?
Thanks

Inorder to root, you need twrp and in order to get twrp working you need to wipe everything first.
I don't know if there is the possibility to backup app data without root, however i found this articel.
Just because I'm curious, which apps are important for you to have a local backup? I went through all my apps and didn't found a single app which isn't either naturally stored in the cloud (like whatsapp, FB, Snapchat,..) or has the function to export/backup things like tasker. :fingers-crossed:
Hi Jaannis.
I have a lot of apps that do not store their data in the cloud but locally in the phone. Without being too specific, some of these are notes, some are social apps (connections with hundreds of different people around the world with conversations, pictures and videos) and some are personal collected data.
I managed to migrate all the data the last 5 years using Titan and I think it's silly after managing to save them suddenly to lose them. On the other hand it kind of looks like there is no other way. Without Titan backup working, I will need to lose everything.

How can I thoroughly wipe and reflash my S6?

My trusty S6 running rooted Android 5.0.2 has decided to act up, more specifically, it crashes and reboots ever more frequently. I can run stress tests and other test apps fine, but when I actually load apps and start using them it crashes after anything from 20 secs to a couple of minutes. This has happened before, but then wiping, etc fixed it. My suspicion is that the nand flash has gone bad. So I'm wondering what the most comprehensive flash erase and reprogramming is that I can do? I've used FlashFire to reflash the CleanROM Lite 1.1 that I use and I've wiped data and cache. That made the device stay up for a couple of minutes instead of just seconds...
Some questions:
- is there any trick to rewrite more of the flash or identify bad blocks permanently?
- if I use Odin, does that provide additional options? An issue is that I haven't been able to find Odin files for OE2...
It's clear to me that I need a new phone, but given the timing of announcements and availability it would be really great if I could eek out a few more weeks on this one...
Odin would be the smart way to go. It has everything needed to wipe the phone, install new ROMs and root

Quick update: I did find OE2 for Odin somewhere and flashed that using Odin. It restored my S6 to life! So I assume that some flash sectors in the parts that don't get reflashed by FlashFire were corrupted and using Odin did the trick. Thanks for the nudge!

Question Xiaomi Poco X3 Pro is constantly rebooting itself to recovery mode:

Hello,
About two months ago I successfully rooted that phone through Magisk. Now I am facing the told problem. I searched for some problems like mine, but it is not because of updates. I do not remember I have done something dangerous for the system. However, I tried to install this package. When I tried with the Android package installer, I got an error "it could not be installed". Then I tried to do it through this app manager for rooted devices, and it just stayed loading for a while until I just closed it. I entered the custom app manager and I realized that the app was recognized as an installed app, but however, I could not see it in the poco app launcher. I launched the app and it worked fine, but when tried to make f-droid a system app it displayed an error "/ directory could not be remounted as read-write". I left it be and removed that app. Everything fine... But the next morning the phone was asking for the SIM unlocking code. I unlocked both, the SIM and the phone, but after about five minutes it rebooted to MIUI recovery 5.0. If once in recovery mode the phone is inactive for a while, it automatically reboots to system. The rebooting time once unlocked the SIM was decreasing to two minutes. Apparently, it only will reboot if the SIM is unlocked, and the time is five minutes when the phone is cold and it decreases as it is being restarted. The phone it is not too hot when rebooted.
Thank you if you spent your time by reading the text above. Now the question: How can I fix it without losing my data? Regards.
PD: I do not have enough time to make a backup till it is rebooted, at least from system, and safe mode did not solve the issue.
You tried to install an obsolete app for moving apps to system, an app from 2016... no less?! What were you thinking?
Let me be honest and tell you that that move was extremely stupid. Chalk up your mistake to a brain fart, take the loss and try to reflash the firmware without formatting anything prior to doing so. Leave internal storage, dalvik, cache and everything else untouched. You just might make the phone bootable to backup your data, and then do a PROPER flash procedure.

So therefore, which partition should I reflash with the stock ROM?

flash the stock firmware with miflashtool and select de option "save_user_data" and done, the firmware will be flashed and your data will stay there

OK, that flash was successful, the root and the custom recovery were lost, but it is still rebooting. Should I flash all?
