Question Bootloop problem - OnePlus 9

Hello,
My oneplus 9 is stuck on the boot loop. I tried to switch it on recovery mode and also tried to force restart but nothing seems to work. I don't want to wipe my whole data as I do not have the backup. Please help me with this issue if someone knows about it

you can get your device back up and running by flashing certain images from the stock rom through fastboot using a pc. I can't tell you exactly what you need to flash as I dont have this device. Maybe look for a tutorial of some sort. As far as I know, you need to flash all images except for data, (i.e. system, boot, recovery, and others). Don't take my word on that, as I haven't done it in a long time, and it varies depending on your device. Proceed at your own risk!

Bootloop help

So I was cruising around the Nexus S forums and found a rom I liked after I unlocked and rooted my phone.
I flashed Paranoid Android and then flashed the Matr1x kernel. Thus putting me in a neverending bootloop.
No ability to go back to CWM so I can't restore. And I can't put it in download mode so no ODIN.
What the heck do I do?
Can anyone help?
BTW if this is actually called a soft brick I'm sorry my terminology might be off.
Also I did this because the last phone I did extensive flashing with was an HTC Inspire 4G and it was easy to flash stuff just clear everything and flash what you wanted no bootloops. Sadly this phone not so much.
Hmm... No recovery...I've been stuck in a bootloop but I had recovery!
Sorry for the useless post, I cant help you..
Are you able to get into bootloader?
Usually when a bootloop occurs you should still be able to go in recovery.
When you say "no ability to access CWM" do you mean ROM Manager? Or the recovery mode?
What happens when you try to access the recovery mode?
same issue like urs
http://forum.xda-developers.com/showthread.php?t=1775933
try clean install;
flash Rom-Wiper.zip
flash Dalvik-Wiper.zip
then;
factory reset,
Format the system, data, cache, boot & partitions of your device.
I mean no access to recovery. CWM is Clock Work Mod Recovery. I have no access to fastboot either. The only thing my phone can do is bootloop.
You have to be mistaken.
Press power and volume up to get into fastboot ( bootloader). Then pick recovery....
That rom or kernel will not erase recovery. If your phone is in a bootloop it is making it past the bootloader
So it appears it as if I was mistaken. I got into fastboot and booted into CWM I'm still confused as to what I did, but I think I corrupted the Kernel.
It was the weirdest thing though. I tried it at least a dozen times, then I tried to run down the battery and try it again afterwards, and it didn't work so I gave up. Then I tried it again about 5 minutes ago and it worked. I'm sorry I cause you guys so much confusion. I've been doing this for so long I guess I just didn't doubt I was doing it right.

[Q] Stuck at Samsung logo during boot even on stock rom

I have soft bricked and then recovered a lot of devices but this one has me stumped. I tried to install a custom kernel that I compiled myself using odin. When that didn't work I tried to copy the image using dd. My theory is that I wrote to the wrong block device and broke something. When it wouldn't boot I figured it was no big deal, I'll just revert to stock. I have tried flashing the stock rom with Odin and by using Kies emergency recovery. Both seem to succeed but whenever I boot I just get stuck at the samsung logo which displays on the screen forever. I can still get into download mode and recovery mode just fine.
Things I have tried:
- Factory reset (I've done this many times from stock recovery and TWRP)
- Cache wipe (Also tried several times from stock recover and TWRP - in TWRP I tried all the different wiping options)
- Flash stock ROM
- Turn off device and wait for more than an hour (since there is no way to do a battery pull)
My understanding is that the bootloader must be functioning otherwise I would not be able to get as far as I do. And since flashing stock ROM doesn't do anything there must be a partition with corrupt data that is not being rewritten when I install the ROM. Any ideas what this might be? Are there any resources I can use to completely repartition the device?
Any ideas are appreciated.
I fixed my problem so I just though I'd post the solution here in case someone finds this on Google or something.
It seems that I did indeed corrupt a partition that is not rewritten when you flash a stock rom or do an emergency system restore with kies (which I believe does nothing more than download the stock rom and then flash it). I actually had to buy a second device and use dd to copy over all the partitions and then returned the second device
So if you have this problem you might have to ask someone on this forum to give you an image of whichever partition you broke.

Nuke the G? Deep wipe/format?

Hi,
is it possible somehow to cleare the partitions "deeper" then it's possible with the build in format command inside CWM?
I tried the fastboot erase (system, data, boot) with the result "permission denied" also.
The problem is the Moto G got messed up during the update to 4.4.
Since that moment the Moto G won't boot up with any stock Rom i flashed and i checked up many, many different stock roms (4.3 and 4.4.2).
It is possible to access recovery. (only CWM-swipe is working, CWM-touch, TWRP or the stock recovery won't boot) (Somehow TWRP booted once, but never again...) Sometimes i even can't access CWM-swipe, than I have to erase userdata and cache inside bootloader.
The other thing is it was possible to boot up the G with the Lego Rom, but it rebooted very often (30secs, 1min, 10secs....)
At this moment even that doesn't work it's getting stuck inside the bootlogo like every other custom rom i tried (Slim, CM11).
This behaviour makes me belief that things must be messed up depper inside.
I like to wipe everything!
Try this to restore your system
http://forum.xda-developers.com/showthread.php?t=2644703
I dont know what happened woth your g , but this delets everything except of the bootloader and then flashes the normal stock Rom, so that your moto g is like new.
It could be that sth. is wrong with your recovery as you cant wipe or flash anything, maybe flashing another recovery via fastboot would make you able to flash roms again and you wont need to restore stock.
Hopefully this works but remember that it doesnt metter what you do, you are responsible for everything and noone else. I dont guarentee that this works.
Hi,
this is what i had done about 40 times with almost 20 different stock roms. They all doesn't boot up
The Lego-Rom is the onlyone which had booted up completly but rebooted automaticly. Now Lego is hanging in bootlogo.
Like i wrote in the first post. CWM-swipe is the only recovery that still works most of the time. And I tried the stock recovery, CWM-touch (philz-touch) and TWRP.
I need to go deeper with the wipe/format if it is possible.
Otherwise i need to dump the G.
Thats really weird. If this all doesnt work then i dont know.
Yep, this is why I'm asking for help! Maybe someone know more.

kep i mind before this method i i tried the guide "restore stock moto g rom" for 2 days straight with fastboot failing to flash it each time. if ur ok with starting anew apps wise try to flash a stock rom.

Need help recovering my phone from bootloop after trying to update custom rom

Today I tried to finally update to the latest version of crDroid, but ended up having a bunch of issues doing so, and after a lot of troubleshooting and trying to fix it, I ended up putting it into a bootloop of some sort instead.
I'm pretty sure the last thing I tried was installing a different version of TWRP to see if that version would let me properly install the rom, and stop my phone from always rebooting into recovery mode.
Trying to turn it on normally or boot into TWRP leaves it hanging on the "Redmi" boot screen, it can boot into fastboot mode though.
I'm guessing that the only way to recover my phone at this point is to flash the Official MIUI rom back onto the phone, but that also involves wiping Data and losing pretty much everything I've put on the phone.
I was smart enough to make a TWRP of the Data folder, but while making the backup, the console said it doesn't include all personal files or something.
How much of my personal data and files can I rescue from the phone in this state, and how can I do that before it gets wiped when fixing it?
Also, I think I really need some help in actually restoring my phone and flashing the custom rom properly.
No matter how much effort I put into figuring out how to do this stuff, unexpected issues always seem to happen, and turns something that initially seemed so simple into multiple hours of troubleshooting.
The only way I think i've gotten rom flashing to work at all was by wiping everything and installing the official MIUI rom, but I don't want to be losing my data every month when an update comes out.
So, could someone please help me get my phone working again?
Edit: I ended up fixing my own issue by ADB flashing on a different release of TWRP, and then installing fcrypt disabler after the rom but before everything else.

Unfortunately, I can't.
Trying to boot into TWRP just gets stuck on the 'Redmi' boot logo.
I just remembered that you can install TWRP over ADB, and that Peter's one says it works even when the system partition is empty, so maybe the issue is the TWRP I installed and could possibly undo this part of the issue over ADB.
It won't fix the issue preventing my from updating my rom, but recovery only is still better than a soft brick.
Edit: That worked, i've put Peter's TWRP back on, and it's launching into recovery mode/TWRP again now
twrp not boot after successfully flash in this rom

first click on extract a fastboot rom and copy boot system and vender file with flash.all bat file and make a new folder then click on flash.bat save user data file to flash these images
or you can do this manually
fastboot flash system system.img
fastboot flash vender vender.img
fastboot flash boot boot.img
then reboot device to fastboot again
now flash latest official twrp builder 3.2.3.1 img twrp and take all your data backup,
in fastboot flash latest miui do not downgrade direct otherwise you lost your data,

In the end, I did try orangefox, and it might have been part of why it worked.
However, the crDroid installation instructions specifically mentions using Peter's TWRP, so I initially used that one.

Thank you for the effort you put into typing up a guide to help me, but I ended up fixing my own problem.
I was able to use fastboot to flash on a better TWRP release, and then get the rom to install properly by installing fcrypt-disabler just after it.

If you can access fastboot, then flash TWRP.... Enter recovery, wipe your system partitions and then flash the Stock MIUI ROM or use the MiFlash tool. Make sure you aren't flashing an older version of the ROM than the onle already installed.

Stuck in Bootloop | TWRP installed

Hi, i just got my old 5 year old (now retired) device to bootup because someone had made a kernel for the device which supports overclocking so for the fun I wanted to try it
but there was one weird problem, it seemed that though the root permissions from years ago remained just like they were but magisk manager itself had lost root permissions though I was still able to grant root permissions to other applications normally
I was on an unofficial Lineage OS build and thought of returning to original Miui for the device, got the fastboot rom, got Mi flash, flashed it, booted up
but there was a catch, it would always throw an error on the login Miui account screen at startup saying "Couldn't check device security, please try again"
I had tried everything possible including:
adding a Xiaomi account
skipping sign in
Inserting a sim
None of them seemed to do anything so i flashed twrp recovery again as using mi flash to flash ur device's stock rom gets rid of custom recovery
Now here is the mistake I made
**I wiped the device clean using TWRP**
now i tried going into adb sideload mode, no matter what I did my PC wouldn't detect my device, tried going into fastboot mode and still my PC wouldn't recognise the device and same goes for Mi flash tool
additionally the device would automatically exit out of fastboot mode within 2 minutes and go on to the power off screen
I do have charge on the device it says it's at 87% on the TWRP menu
I can no longer bootup, im stuck at the MI logo on bootup
Device: Mi Max 2
Additional notes: I am not in a hurry as that is not my primary device so it is okay if you want to take your time to reply, even if there's no way i can get my phone to see the light of day again it's alright as the phone was retired and sitting collecting dust for 2 years now
I do not wish to visit a service center as it's not worth it for a device I'm just gonna use for a few hours then put it back into its grave again
just download that same, or another custom ROM, and flash it via TWRP (just put ROM in SD card).
Nothing is gone, i mean if you delete system via twrp of course it will bootloop as it don't have system.
And for reverting back to original stock ROM , i think it have to do something with encryption, or maybe just the fact you unlocked bootloader.
Best is to stay away from stock ROM, find some custom ROM which have similar to MIUI (stock rom) , somewhat improved, if you want to get as much stock ROM experience.

Hi, thanks for the reply, I tried using an SD card and unfortunately it wouldn't detect that too, what i found was I didn't wipe System it still shows that it's taking up some place (3597 MB)
i would be fine getting a custom rom on the device infact i have crdroid ready to be installed
could it be that the TWRP i installed (yes I downloaded the latest version and didn't flash the old one i had years ago) have some bugs? (I did install it from official TWRP website)
also note: though you see a Senior Member title below my name, im a complete and utter noob

Lol I thought I was the only proper noob here on xda but nice to meet other noobs here too .
I think Kraken-gz is right, once the older devices are OEM off-support its best to stay away from OEM servers, I lost couple of old lesser-known-brand devices to OEM mischief i'd say coz it happened twice to me when I reloaded the original ROMs and tried to connected to the net they went dead on the next bootup, I think the OEMs have something going on there to boot out the older devices so newer ones could be pushed in the market sooner than they were supposed to. Possible.
so, first, in twrp, try to completely format it, follow this to do it
Just, a note: in advanced wipe delete system, data, dalvik cache and cache.
When trying to reboot into system, make sure twrp complains that it have no system. (that way, you know you deleted it)
reboot it, again in twrp.
try to flash custom ROM, should work as it have clean memory.
If it doesnt flash, then make sure to note all log file from twrp while flashing, and post it here, in order to see, what failed in flashing. If it succeds, it should load custom rom . If custom rom dont work, try another one, maybe older, or one that you had previous time (before trying to go into stock rom) (just, to try to boot it somehow. But before trying another custom rom, if one fails, do proper wiping described above.
If that fails try to download oldest stock ROM, and flash it. Maybe newest is blocking it.
If that fails, there is something called EDL mode, when fastboot is not available (for hard brick, like this).
here is video just to give you overview how to do it
and text also
Edit:
WAIT, try to format it, without wiping system. maybe it will boot again.
If not, other solutions are not applicable, if you dont find way to detect that sd card. Only EDL remains.

Tried wiping data, cache and dalvik cache and formatting data, none seemed to help
and still no sd card being detected
Now edl mode
I would love to boot into edl mode but the thing is my device isn't being recognised by adb nor is it being recognised by fastboot commands
so that's where I'm stuck for now
