OP7T HD1900 Keeps Restarting - OnePlus 7T Questions & Answers

Hi, is there anyone who has ever encountered with such issue? It just randomly restarting. I've done a MSMTool Unbrick Method but no avail, it booted but still randomly restarting. I suspect there is a hardware malfunction.
List of issues that I encounter :
1. Random reboot, a lot
2. Blinking screen on and off when boot animation shown
3. Always fail to do system update, locally and OTA
4. Google play store, gboard, oneplus launcher keeps crashing
5. ???
Will update the list once I remember and encounter a new one.

I've tried multiple method but still no sign of good news. I've tried wiping data & cache using default recovery, all in one tool and lastly MSMTool. Pls help!

Anyone?

Now, even MSM Tool cannot detect my device.
At first, my PC detected my phone as Qualcomm HS-USB Diagnostic 900e, something along that line. And then I found this tutorial to convert that into QDLoader 9008. But when I clicked enum, my MSM Tool didn't detect anything.
Few days ago my device start to restart by itself and then bootloop.

Normally I got bootloops in other phones (HTC) coz of MY fault always - like flashing wrong firmware or wrong version of boot.img but just like this bootloops is quite strange.
Maybe send it back - warranty if your bootloader is still closed etc.

I am really sad that my device still keeps restarting. I've countlessly tried to reflash the software using whatever tools exist. I've noticed something though, when playing youtube video, the video sometimes breaks (blur, I'll attach the ss later) and after several seconds it became normal again.

Phone boots into firmware update

I recently updated my lg G3 ( Google patch update named Aug-18-2015 etc) and it started to malfunction with resets, crashing and eventually got it stuck in boot loop. Then it booted into a green screen that said "demigod crash handler/tz crash" thrice. Instead of a hard reset I decided to using the lg mobile support tool to fix it. During the upgrade recovery my phone went into download mode/firmware update. I could see the progress bar moving and then get stuck and my mobile would switch off. Took out the battery, disconnected and reconnected the phone and tried the process all over again but in vain. I repeated this at least 8 times and eventually gave up. Now my phone is basically useless and only boots into firmware update. Hard reset doesn't work either. Can somebody please help me fix this?
Android version : 5.0
Kernel: 3.4.0
Firmware : v20t-ame-xx
Did you try to unbrick/unroot (there so much video about it) it should fix it

I have tried everything available online but nothing works. Im so frustrated atm. :/
Could you enter recovery. Connect your phone into your computer in firewall update and after go on adb and fastboot commends and type adb reboot-recovery

Yet another help thread with a hard brick/soft brick OP3

The mom needed a device and I dug out my ol OP3 (rooted). It was stuck in a boot loop and I decided to flash it back to the original factory settings. But from there on it would never boot into RECOVERY only into FASTBOOT. So with ADB still working I used the many available "Mega Unbrick Guide for A Hard Bricked OnePlus 3". The main problem was it would load and then faced with 3 errors upon trying to boot. Corrupted MD5, error with recovery and something else. I never had a problem with the drivers part and the main hang up was with either using the x64 or the x86 driver. But with no luck neither worked and always showed the same FAIL.
After many hours of no luck, during a load the phone disconnected on its own and the computer showed that something changed and no longer recognized the previous connected device.
Now resulting in no response to any action of any combination of buttons. Please explain how this can happen again, and could possibly be prevented in the future. I have rooted may devices with loads of help from the XDA community and have now experienced my first hard brick..kinda embarrassing when I told the mom she would have a killer device in about an hour resulting in full embarrassment!
After leaving it on the charger for a bit, it still was able to connect to the computer and run yet an UNSUCCESSFUL install with MSM download tool v3.0.
Thanks guys for reading.

Bootloop without solution? happened suddenly

Hi everyone.
I have been reading a few posts about bootloops in hopes that someone would have been facing the same issue as me. It seems my case is a bit different. I am desperate for some help!
My Max 3 came initially with a chinese ROM but I followed some wonderful tutorials here and I unlocked it and installed initially the xiaomi.eu ROM. Then a couple of months later I installed AOSiP ROM, I updated it a couple of times dirty flashing over it, and settled in exactly the "AOSiP-9.0-Pizza-nitrogen-20190719" build. And there i was, for 4 months, all stable, then suddenly today I was going to unlock the phone with my fingerprint and asked for password.
This happens exactly 1 time per day but I noticed that today it was the second time. Then doesn't matter how many times I put my password correctly, it would keep asking for my password. So I decided to restart the device... and then the bootloop issue started. It starts, reaches the moment in which the AOSiP logo shows and (not even 1 second until the logo shows) freezes, and restarts the device.
I can access the recovery without issues so I didn't panic yet, I backed up all I could, wiped everything I could, started from zero: firmware 9.9.3 + AOSiP-9.0-Pizza-nitrogen-20191117 + gapps. The bootloop still there, in exactly the same way. So at this point I have no clue what could be the reason. I was always careful not to trigger any anti-rollback, it was all going good, now not even with a full factory reset seems to work. I even reinstalled the recovery.
Any ideas? does anyone know what could I try next? Thank you very much advance.
I forgot to attach some logs. I got using the TWRP Advanced > Copy Log option.
Well, I guess I completely screwed it now. I had the brilliant idea to go back to some of the original steps I did way back and flashed an old xiaomi.eu ROM "xiaomi.eu_multi_MIMAX3_8.8.9_v10-8.1", that completely bricked the phone. Screen doesn't even turn on anymore. Is it the end for my Max 3?

The mi max 3 has arb enabled, so flashing old rom can cause it to brick.
Have you tried different button combinations to enter fastboot? If you can get to fastboot, just flash a fastboot rom, if that works.
If the brick is caused by triggering ARB, then that may cause some issues, and may need an Authorized Account to flash the ROM from scratch, with some qualcomm flashing tools things.
Though, there may be some way to bypass the authorization for mi max 3 on the internet and have your device unbricked.
Thank you for your replies. Yes probably ARB, I thought my phone had never installed a ROM with ARB and so I was safe to install xiaomi.eu_multi_MIMAX3_8.8.9_v10-8.1 (which it is also to be pre-ARB), but I guess I made a mistake at some point.
Situation now:
- with Mi Flash I am getting the authorization error with almost any ROM, with very old ROMs I am not even able to start the flashing process
- with Qualcomm QFIL tool I always get an error "function: sahara_rx_data:237 Unable to read packet header. Only read 0 bytes". And I also tried with the patched files from here https://forum.xda-developers.com/redmi-note-5-pro/how-to/fix-arb-bricked-device-qfil-t3841780
I think at this point I tried everything that can be tried. My bootloader was unlocked, but at this point I am not even sure if its unlocked anymore since I can't see anything on the device screen.
The only positive thing is that the phone always shows under the Windows 10 device manager "Qualcomm HS-USB QDLoader 9008", so at least is a bit alive, and with the Mi Flash at least for some ROMs starts the flash process. I am not sure if disassembling it and trying things like removing the batter would make any difference.
If anyone knows any other way to bypass authorization please let me know.
Here I am back with another update:
- I fixed the full brick by disassembling the phone and disconnecting the battery, with the battery disconnected I could finally flash a Chinese ROM. That however was just the beginning... more problems came
- Common problem I guess is that after booting with that Chinese ROM i was getting a message about how the encryption was interrupted. This was easy, just changed the file system of Data and formatted it and it was fixed.
- Now I am stuck in another hard to solve problem. Any ROM that boots will not allow me to use WiFi or SIM cards. And the reason is that the IMEI is not set anymore. Reading about it I see that this is related with the EFS partition being corrupted. Nothing seems to work now. I don't have any EFS backup . Anyone knows how to fix the IMEI in this case?

5T - device corrupt

Hi Everyone,
I have a 5T running android 9 - completely stock. The device is SIM free, I have never customised it at all - if anything it's never been connected to a PC even.
A few days ago I was using my phone as normal (on whatsapp) but it completely froze. It now boots up to the "Your device is corrupt and cannot be trusted and may not work properly" - it freezes on start up and won't work at all.
- I can get to the fastboot screen
- I can get to the recovery screen to install from ADB
The fastboot screen says in red - device state - locked.
The device is a clean, un-customised phone. Only a few days prior I checked for any OTA updates but I haven't received android 10 yet.
I haven't flashed phone firmware or anything for years now. (By years, I literally mean years - back in the Nokia 8210 days). My only other experience of flashing firmware was with Samsung phones and 'debranding' them.
As I was not trying to root the device or anything - how do I fix this issue? I've searched the forums but I cannot fine a scenario similar to mine therefore I'm a bit confused as to what to do to resolve it.
I've tried to sideload this - oneplus.com/uk/support/softwareupgrade/details?code=PM1574156155944 via recovery but it says installation failed.
Any help appreciated thanks!
Sounds like you're straight out of luck to recover any data if your device is completely stock, as to unlock your bootloader to access encrypted data would mean a factory reset. You could try try one of the unbrick tools using the guide here. You will lose your data.
I tried the unbrick tool here - forum.xda-developers.com/oneplus-5t/how-to/oneplus-5t-unbricking-tool-confirmation-t3733012
... and it doesn't work. The phone now boots to a blank screen with a constant white LED.
Could this be a hardware issue?
I'm not too concerned about losing my data - already gave up on trying to keep my data when the problem first occurred!
After the 4th use of the unbrick tool (each time it completes successfully) I was finally able to boot into the phone.
I got as far as setting the region but then it wouldn't find any wifi networks. It then completely froze on this screen and is now back to "your device is corrupt and cannot be trusted" and will continually try to boot and freeze on the oneplus logo. Sometimes it will boot to a blank screen with a white LED.
Has anyone else had this issue? I'm definitely suspecting a hardware issue now...

Problem fixed?
unfortunately not. Any ideas on next steps?
That's an odd issue for sure. My only idea would be installing TWRP and maybe formatting from there and using fix permissions etc. to see if it has any effect.
I've done some googling to try and understand "TWRP" but I'm not sure I fully understand. Are there any forum posts I can refer to?
- phone has been flashed several times
- before this whole saga dev mode was enabled, but only to reduce animation scale - USB debugging was never enabled
- the phone has always been stock / sim free - never rooted
Thanks
Can you get into recovery? If yes then try connecting to a pc whilst in recovery as it should let you open your phones internal storage on PC but im not too sure if stock recovery allows it, (TWRP) does. Then copy whatever files you need. Let us know if you can get into fastboot mode aswell
It sounds similar to an issue I have just experienced with a friends 5T. In my case it's a hardware issue (seems like Wi-Fi has died). Just for kicks try to flash the Android 7 firmware. For some reason it allowed me to boot the phone fine and use it, albeit without any Wi-Fi. I sideloaded OOS 4.7.6 and that seems to be the last version 7. You could also use the older unbrick software. Academic I fear as I think you have a hardware issue.

Crashing problem after installing /e/OS

Hi,
I bought a Moto G 5g Plus and instantly unlocked the bootloader to install /e/OS. I did everything exactly like the guide and everything worked, except that it randomly froze for some seconds and then restarted. Because of that, I tried installing LOS for microg but ran into the same issue. After that I wanted to install stock firmware with Motorola's own RSD software, but it couldn't set the phone to fast boot, so I tried to do it with the batch file included in the firmware zip just to see that recovery mode and fastboot now both show the no command error. After restarting, somehow /e/OS started (no clue how or why) and that's the point where I'm stuck.
I can't reinstall because of the recovery thing, and my OS is unusable because of the crashes. I would guess it's some background service that's crashing it, but I'm not an expert. Did someone have this issue in the past and can help me with this?
Thanks!
