lost wifi after twrp restore - Nexus 6P Q&A, Help & Troubleshooting

Hi guys.
I installed TWRP and rootet my phone with magisk and everything worked fine. I then tried a couple of custom kernels before I restored my TWRP backup. Now I can not turn WiFi on. Can someone please help me.
Is there any way to restore it safely and correctly, maby some file I can download that fixes the problem? I really don't want to flash original firmware allover again..

May it is enough if you flash the boot.img of the rom from which you made the twrp backup. I guess you have the rom file on your sdcard, unzip and flash the boot.img with twrp. Or dirty flash the rom if you're to lazy for a clean install.

I was on stock android 8.0.. So I guess that won't work.

Why this shouldn't work ?? You can flash boot,system,recovery and vendor.img of the unzip factory image with twrp, except bootloader and radio of course, but that's not necessary anyway.

LOL, fastboot flash stock boot, system, vendor.

Btw, if you're flashing to test some custom kernels you should have always the original boot.img from the
rom you're using on your sdcard. First flash the boot.img before you flash the next custom kernel, and don't flash a custom kernel over the next custom kernel.

Do you guys mean my backed up boot? Or should I download this files from somewhere?

If you backuped the original with TWRP, you can use it.
Otherwise download your rom, unzip and look for the file.
To solve your WiFi issue u have to dirty or clean flash anyway with TWRP,fastboot or flashfire. Whatever you prefer.

Okay. Yes i backed up the original. I will try it now

It worked when I only recovered system, boot and data

Flashable Stock N9005 Kernel

My battery life has took a serious turn for the worse every since experimenting with a few different kernels, I'd really like to go back to stock 4.3 n9005 kernel. I did factory reset, but as suspected that didn't return the kernel.
Please help.

Cant get out of this boot loop, still have access to TWRP but cannot do anything from there
Have you tried booting into recovery and clearing data. Do you have a backup? I don't no Twrp verywell as use cwm but I think its under wipe.
I have TWRP recovery but no backup, clearing data not fixing it unfortunately oh god

If boot loop happen after u flash the kernel than u flashed the wrong 1. Need to match with the firmware u're using. Try other custom kernel for 4.3. If u really planning to flash the whole rom then there is no need for custom kernel

s5 fix from bootloop what to do?

So after a week of just bootloop, black screen of death and hard reset my rooted s5 suddenly open again.
Now that its open again what can I do to fix this? Cause im afraid that if i'll restart my phone i will get stuck in the bootlooop.
Suggestions?
Just to give you an update my s5 has been rooted for the past 2 years ...its just now that it got stuck in the bootloop.. im not really sure what caused this cause havent installed any apps that could affect the system...
Any ideas how can I fix it while its working again?
Would help if you gave us the model S5 it is, which firmware it's running, recovery etc?
Its g900f using stock rom... stock recovery
Please see attached file
Thanks in advance.
Download stock ROM using samfirm (or sammobile .com)
http://forum.xda-developers.com/galaxy-tab-s/general/tool-samfirm-samsung-firmware-t2988647
Put phone in download mode
Connect to PC USB > add .MD5 ROM to AP section in ODIN 3.10.7
Flash
Boot to recovery > Factory reset
Any other fix without flashing?
Any other fix.. that doesnt require flashing?

Why don't you want to reflash? If you're rooted you should have backups.
Ok I think I missed that part... ok so if I flash, everthing will be wiped out right?
How do I back it up?

No it won't, and for a proper backup you need TWRP recovery
If your phone is having problems like it is, you very likely need to flash
Just flash the stock ROM over the top and your apps and data will remain
But backup photos and important files first by connecting the phone to USB and copying to PC
Forget about apps, you can reinstall them if something goes wrong
Ok thanks im starting to understand it now.. i just need to confirm a few things before i start doing it...i have watched a few vids and ok i think i missed installing a custom recovery... ill install it later and go with cwm...
Flashing the stock.. means getting my firmware(which has the size of 1gig+) in sammobile ang flashing it using odin right?
Read my 2nd post
Thanks alot got it! One last question , suppose that im not going to lose my apps but am i going to lose root once i have flashed the stock rom?
Yep, just root again, instructions are all over the forum, easy to find
Because you're getting bootloops, I suggested factory reset too, that will wipe the device, the flash won't, the reset will
I assume here's the steps that i need to take
1. Back up through cwm
2. Flash stock rom through odin
3. Clear dalv cache
4. Factory reset through recovery or from the homescreen setting?(will this removed supersu?)
6. Root device again
5. Restore back backup from cwm recovery?
Better method:
Flash TWRP 3.0.2.0 (Much more powerful recovery)
Make full Nandroid backup in TWRP
Wipe everything apart from Internal and External storage
Boot into Download Mode
Flash stock ROM with ODIN 3.10.7
Reboot
Now boot back into download mode
Flash TWRP 3.0.2.0 again
Boot into TWRP
Flash systemless SuperSU 2.72 beta or whichever is the latest beta atm
Don't restore your backup or you could end up with the same problems as before, I recommend using TiBu to restore your apps and data from the backup you made in TWRP

Unlock your bootloader and try again

Bricked (No OS installed, Only TWRP)

Title explains it all, I recently installed TWRP so I could edit build.prop to get the google assistant. It worked btw, but I wanted to flash the pixel launcher and when I did, I rebooted and it gave me: encryption unsuccessful. I read online that i should just say yes and just wipe cache in twrp. It asked for a password in TWRP so i pressed cancel and I wiped cache. Boom! I was stuck in a TWRP bootloop. Now I tried to wipe everything but I wiped /system. Somebody please please please help me!
As long as you have access to TWRP you should be able to recover. If you need to restore the system partition you could use this DEODEX version. Follow thread instructions (download RAR, extract system.img, load to SD and flash via TWRP).

I FIXED IT! I am making a thread later on how I did it!
Fixed this by restoring stock recovery.img.
Of course I lost TWRP and root, but it's progress.

TWRP not booting system

I tried to factory reset a custom ROM, got sent to TWRP then I can't reboot to system from there. Tried a clean install but to no avail. I've looked around on the internet and I think I have to reinstall stock ROM and then reinstall custom recovery and ROM, except if I were to install the stock ROM once again (with sp tools) I need my phone to be turned off, not in recovery mode. So how exactly should I proceed now?
EDIT: Managed to get rid of the TWRP bootloop by restoring from a stock nandroid I've found on the forums, coupled with flashing a stock recovery image using TWRP. Reunlocked bootloader, flashed TWRP all over again and then flashed custom ROM and Gapps. Everything running fine now.
Mods feel free to delete this post since it's solved itself, or leave it in case anyone needed help concerning the same issue, up to you.

can you put a link where you find the stock recovery, cos i've restore stock recovery on twrp but my device keep booting to twrp

How do i install teamwin ?

I have a i9000 and i would like to install twrp so i can install a 7.0 rom but i dont know how to install twrp can someone tell me how?
I would also like to know this as well. I've tried CWM through odn but it's a zip so wont flash. I've tried it in stock recovery but obviously get the signature fail msg.
TWRP comes with the kernel and hence the ROM.
It gets automatically installed if you're on older BML/MTD device..
In which case you should have rebooted after acceptign wipe..
Ahh right, so I flash a new kernel to it and that comes with the recovery built in.
Do I flash the kernel from odin or stock recovery. Got the stuff to unbrick the phone if that happens, just wanted to know the right way before flashing stock rom back and starting again.

The kernel is flashed by the ROM zip... I dont remember if it automatically reboots to recovery or not..
However it does create a file in cache that makes it boot to recovery.. Since the /system is not yet installed.
You should flash the ROM after it boots to new recovery.. then install the zip file again..
All this is described in https://github.com/xc-racer99/android_device_samsung_aries-common/blob/aosp-7.1/updater.sh
I got there in the end.
I flashed CF-Root-XX_OXA_JW4-v4.4-CWM3RFS.tar with odin, then installed cm-10.2.0-galaxysmtd.zip which also updated my older CWM. It had a spam, so I wiped/factory/dalvik etc from the updated CWM and then reinstalled cm-10.2.0-galaxysmtd.zip - now running the rom just fine.
Will be trying out some more over next few days now I have a nandroid of CM10.
Thanks for pointing me in the right direction.
