Wifi and whole bunch of sensors aren't working. Corrupt system?

So I've recently got my hands on a dirt cheap OP3 with problems (seller did warn me of those but I thought "how hard can it be to fix them?")
To start with: OP3 A3003, OOS3.1.2, TWRP and SuperSU. IMEI and Baseband are in tact, I can make calls and use LTE, so it's possible to live with it, but those couple problems ruins whole pleasant oneplus experience.
And problems are:
1. Wifi doesnt work. At all. It can't detect any networks and for MAC adress there is weird 02:00:00:00:00:00
2. None of the sensors shows any signs of life, checked with Sensor Box app and *#808#
There is a perfectly good explaination for both of those: root browsers shows /persist completely empty. So if there is any way to fix this lovely piece of modern tech - only this place can provide it. So help, please ;]
P.S. Soft/hard reset and reflashing aren't helping obviously, nor does deleting /persist - after reboot it appears in same state.

My OP3 has Wifi, GPS, Dialer works but none of the sensors work. I tried everything from flashing roms to using unbrick methods but nothing works too.

Maybe contact OnePlus support, they may be able to fix it via a remote connection...

Did you try the second method discribed here ?
It will rewrite everything on every partitions if the device. https://forums.oneplus.net/threads/guide-mega-unbrick-guide-for-a-hard-bricked-oneplus-3.452634/

Ok, so I've pulled persist.img from the toolkit, flashed it right after "erase persist" and that revived all of my sensors! Yay! I guess that toolkit might help with wifi as well, tho no idea which part of it. I'd use whole procedure, but there is one problem here - it needs bricked phone to start with.

on my lg g2 days, when screwed pretty bad with something, there was a script for nuke laf partition to boot qsbulk mode (and also erase whole emmc for real clean start), dunno how/if there is such a scrip for op3
Sent from the grey stuff inside my skull

If you wanna brick your phone its easy. Install 4.0.2 and then root and make sure you have TWRP of course. Download the OTA to 4.0.3 the small one not the full zip. Flash that in recovery. You'll be bricked

Thanks for info, nice to know ;] Although I'd like to avoid such drastic measures. Better to pin a roach with a needle instead of nuking it, right?

had the same issue, OnePlus replaced motherboard for free.

Bricked Galaxy A3 2017

Hello everyone, I decided to root my phone today. First I enabled OEM unlock and then installed TWRP, no problems with that. Then I tried to install CF autoroot through recovery and everything seemed fine. When I tried to boot up my phone it said something like integrity check failed and I had to do a factory reset to be able to even start the phone. I did not do that but tried to install official samsung oreo firmware through odin but it won't install, just fails. Then i got other error message saying "an error occured while updating the device software. Use the Emergency recovery function in the Smart Switch PC software". The only thing I can do now is enter download mode and nothing else but odin does not let me flash anything. I'm desperate here so any suggestion would be great. Model is SM A-320FL btw. Sorry for my english and lengthy post

What kind of error do you get in Odin?
Is it the one that says something like "SW Rev. check fail"?
If so than for me it worked to flash the bootloader and modem of Oreo and the after that i reinstalled the OS without any problems.

First it was just a red fail for BL, CSC and those other things and later it just won't even start. When I try to install TWRP it goes to half and stays there. Thanks for the suggestion though.

Was your device from a carrier, if so, try to flash the firmware that your device came with. If you can't solve this, PM me, so that we can try to resolve this on Telegram, Discord etc. :highfive:

Thank you for the reply, I don't think it was from carrier, when I tried to flash firmware I downloaded latest firmware from my current carrier so I think that shouldn't be a problem. I'll contact you tomorrow because i'm just too tired now. And update, I can flash TWRP now if that is of any help.

It is solved now, thanks everyone for your help

Hi. Glad to see you got this sorted, but it may be useful for other users to see what you did to resolve this.

Yes, how did you solved that.
Looking at two A320F I found one difference:
One has AP SWREV B:2 K:0 S:0
the other one (that makes trouble): AP SWREV B:3 K:1 S:1
What exactly does it mean.
Flashing with Odin gave me erros (on device, Odin just say "failed") depending on flashing BL (SW Rev Check failed )Bootlader Device: 3, binary: 2 , while flashing AP gives Kernel Rev check fail.
So, how to go on? I was able to flash TWRP, but not Stock (neither an old 6.0 nor 8.0).

Ok, solved it. Flashing stock will probably only work to same or newer versions, not for downgrade (at least not without any special tricks that I don't know).
After downloading the latest stock FW , odin passed.
Now I still have the problem, that I can't transfer data partion from one A3 to another one.
https://forum.xda-developers.com/showpost.php?p=78062070&postcount=71

My first error was that I downloaded wrong firmware for my phone and because of that odin gave me errors. Second error was that I tried to wipe data through advanced wipe, but I needed to format it by pressing format data button. After doing that I was able to flash official stock ROM, install TWRP and root my phone. User MartinYTCZ helped me greatly with this, big thanks to him again. :victory:

Can't you backup your internal storage on PC or SD card, contacts, messages, phone calls, settings on samsung account and apps and data with titanium backup? When I flashed stock ROM I lost all data from my phone so be careful with that.

Locked out of J2 Core (SM-J260T1)

So a good friend of mine recently changed the lock screen password to his Samsung J2 Core (SM-J260T1), and then forgot what he changed the password to. He's really pissed, and I completely understand why; most of the files/pictures he has are on that phone. I've tried Dr.fone, but it doesn't have a working unlock function for his phone, I've tried numerous other 3rd party Android screen bypass tools, all to no avail. Now I'm looking into recovery mode options, but as far as I know, TWRP doesn't have an official custom recovery download for his specific phone model number (SM-J260T1).
I found this: https://forum.xda-developers.com/showthread.php?p=32965365#post32965365
..but it's way over my head. I've searched online for other custom recoveries and they do exist for the SM-J260G, (for example, TWRP -_-), but I'm not sure if these custom recoveries are inter-compatible with his J260T1 and I'm scared to try out of fear of bricking his phone.
Problem:
Forgot Android lock screen password, can't get back into phone
Constraints:
-Android lock screen password unknown
-USB debugging is not enabled on the phone (*If anyone has a "USB debug enable file" I can flash using the stock recovery mode, or a way to enable USB debugging from via PC USB connection, let me know!)
-I'm pretty sure developer mode hasn't been enabled either
-He has a Google account linked to it, but correct me if I'm wrong but Google updated the FMD options to where you can't send the phone a new password remotely; it'll wipe the device.
-Wiping data/factory reset is an absolute last resort option because the phone's not backed up.
I can get into recovery mode, and with ADB running on my computer, I can select the
Code:
Apply update from ADB
option, and it'll show up on my PC's ADB as:
Code:
O:\Software\platform-tools_r29.0.0-windows>adb devices
List of devices attached
420087d0d35ec5ed sideload
I'm pretty sure that's this function: https://twrp.me/faq/ADBSideload.html
Not sure if I'll be able to do anything using adb sideload, but it's something I'm able to use (if there are any working files for the SM-J260T1)
I can also
Code:
Reboot to bootloader
and
Code:
Apply update from SD card
(I have a 32GB SD card if I need to use it)
Does anyone have any ideas as to how I can get back into this phone? Thanks to everyone's advice/info/answers in advance!

you do know why lock screen exists, right?
(to be clear, there's a lot of threads in here that have this same problem. If you cannot get it, who knows if you are an actual owner or not. Only way to get in phone that doesn't require a few bucks is factory reset)
That said, throw a few bucks at a technician might be a good idea.

find device storage corrupted your device is unsafe now

Im using MI 6 since last two weeks i am facing Error "find device storage corrupted your device is unsafenow" and already it’s been reset two times!
the wifi is not enabling and some of sensors are also not working i am in very big trouble
the bootloader is locked and i am not able to flash the official stock ROM
i have tried to download latest package from update and installed but not get success
I've seen many tutorials to solve this problem, but the thing is I've to unlock bootloader! My phone bootloader is still locked
What should i do now!
Experts please help me to sort out my problem!
Thank you.

I've heard xiaomi phone can use 'fastboot oem edl' even if it is not unlocked.
Maybe you can search something about that.
Hope that helps.

Good point. I have the same problem. I will try edl mode.

i am also getting this, have you solved?
---------- Post added at 11:48 AM ---------- Previous post was at 11:07 AM ----------
Reflashed using edl, problem still continues.

Edit, posted in wrong topic

You can try to use XiaomiTool and flash your phone with instead..
Check if your device is still encrypted, if not, that's likely the reason why it tells You storage is unsafe.

Is it solved? The same problem
Help

I had same issue. I unlocked bootloader, flashed twrp format data and then flash xioami eu and it works.
If you want to flash Global or other official you have to use miflash and tgz rom. If you, after flashing, see a corrupted memory try from fastboot the command:
fastboot format userdata

I also have this problem, but my status is strange. I use Xiaomi Flash Tool to flash the offical rom 10.3.4. When I boot to system, I get the error message, "find device storage corrupted your device is unsafe now". I flash the newest rom 10.4.3 from miui.eu, everything is good....><"
When I get this error, I have tried to enter fastboot mode and enter the command, "fastboot format userdata", but it's not work.
Have anyone also this problem and solution?

Were you able to find a solution?

I have the same problem in my Mix2 having followed the instructions to move from the now stopped Global Developer ROM to the Global Stable. I followed the directions carefully and after unlocking the bootloader, flashed using the fastflash method choosing to lock the bootloader again. On starting up the phone, I have all the problems you describe, including no way of signing into my Mi account to reflash the phone. [email protected] have been contacted but their suggestions have not addressed the fundamental problem of the corruption also blocking my ability to log into the Xiaomi account to unlock the bootloader.
This has been a very good phone but now!!!
Did you find a way to unllock the bootloader? It seems to be a problem for quite a few people and it would be helpful to know if it is still worth trying to rescue the phone.
Thank you in advance. You described the problem very clearly,
Chris

On xiaomi mi 9t I installed
Code:
davinci_eea_global_images_V10.3.12.0.PFJEUXM_20190801.0000.00_9.0_eea_1d38ae0ec5
and
davinci_global_images_V10.3.11.0.PFJMIXM_20190802.0000.00_9.0_global_ea6683ef55
two times . device storage corrupted every time
3rd time installed davinci_global_images_V10.3.11.0.PFJMIXM but logged in with miaccount during first configuration and error is gone..

i have this problem in redmi note 8, after trying xiaomi.eu rom, i have flashed stock rom again via twrp and now i have that error.
is it solved already?

I have removed the problem, but I don't know the root cause. I install third rom and rollback to miui eu rom, then the problem is disappeared.
1. Install OmniRom(clean dalvik, cache, and internal).
2. Install magisk to root OS(clean dalvik, cache, and internal).
3. Boot to os and reboot to twrp.
4. Reinstall xiaomi.eu_multi_MI6_V10.3.1.0.OCACNXM_v10-8.0.zip.
5. Boot to OS and I find the problem is fixed.

Well I got a solution from telegram group.
People having this problem can flash persist.img . But this worked on POCO F1 , don't know about other devices . Y'all can try and let other know.

Bootloader auto locks, can install TWRP but asks for password.

Hello,
New to the forums, I've come across a Nexus 5X that has got me stumped. I haven't had to create and post on xda-developers before because I could always find a solution. But this phone...I've even got the book (xda-developers Android Hackers Toolkit)
So I needed a Nexus 5 for a project. I went to ebay and ordered one from China/Hong Kong.
I've got TWRP installed but the device asks for a password. I've tried different versions of twrp. in the more recent version TWRP asks for a password. In earlier versions it just runs a script and reboots.
I cannot yet post links to images, being a new member.
I'm not sure what I'm doing wrong. I can run fastboot oem unlock and unlock the device. Then, if I try and flash a stock good android Nexus ROM the bootloader locks itself and reboots.
Is there something obvious I am missing? I just want to wipe the phone and install a stock nexus ROM. It's like the people who sold it have it loaded with something the prevents the phone from being wiped/modified.
I've never come across an Nexus phone that I couldn't wipe. I don't care about the data on the phone. I cannot securely use a phone if I cannot wipe it first. I can get to the bootloader and TWRP recovery. But there is no
point with TWRP because when it prompts for a password and I click cancel it runs a script, reboots and then locks the bootloader again.
Thanks

"bootloop_after_lg_replaced_mainboard_bootloader reddit"
google it

https://forum.xda-developers.com/nexus-5x/help/req-help-to-unbrick-t3251740
This is the droids guide you are looking for...
Hope this helps anyone else who lands here with the same issue.

First sorry my bad english. I guess you took wrong way.
I suggested safety and easy solution. TWRP needs password due to encrypted data partition.
If you can format userdata,TWRP require no password and you can flash any Rom.
I wish you success with your way.

Thank you for your reply.
I am following the instructions here; https://forum.xda-developers.com/nexus-5x/help/req-help-to-unbrick-t3251740
I am stuck at the google logo. The bootloader is locked and I cannot unlock it because I cannot get the system up to enable developer tools and allow unlocking.
I don't really know what else to do.

The last resort
h ttps://ja.aliexpress.com/item/32846103543.html?spm=a2g0o.cart.0.0.74743c004Bny1g&mp=1
There is no longer anything that I can do for that.

I've managed to recover the phone using a combination for LGUP + tot files and sideloading an OTA from google.
I want to turn off encryption though... not sure how to do that..

Can you manage bootloader unlock?
O.K. following the tut of reddit thread and use fastboot tool this ver.

Majisk latest
Probably no problem

Hi mate,
I managed to flash TWRP. I booted into TWRP and selected to keep the system read only. I then used 'adb push' to push Magisk to the SDCARD and successfully flashed Magisk. I can boot back into the system and I have root access. Where do I go from here? I would like to install a custom ROM
thanks mate.

OK.
So. I installed Magisk successfully. I setup the phone and rebooted into recovery. It no longer asks for a password. I was able to push a custom ROM to the SDCARD and flash using TWRP.. I have learned alot about android and the 5X in just a couple of days.
Thanks
