Razer Phone stuck in bootloop

I tried to update to the latest update to the Razer Phone and was able to install it successfully, but when I went to install Magisk on the new update, it caused the Wifi to stop working. For that reason, I tried to restore my old TWRP backup I made prior to updating which everything was working before updating. I wiped cache, dalvik, data and system and restored my old backup. Now when I try to boot, it gets stuck at the Razer logo and doesn't get past that. I also tried wiping data and restoring the system image only to no avail and it didn't do anything.
Have you tried booting to TWRP and booting The other [email protected]
How long did you wait on the Razer logo.. When I reset my phone after relocking it.. It took 10+min for first boot. I was scared it wasn't gonna work but I just left it alone and it eventually booted itself up

Thanks. I'll try that and see if it works. But I let it sit for 5 or so minutes.
Edit: I'll go ahead and add it was stuck at the Razer logo. It never got to the actual boot animation.
Edit 2: I let it sit for 20+ minutes and it wouldn't boot or get past the Razer logo.

Yes I've tried switching slots and it didn't work.
Any luck with the stuck at logo screen? I followed instructions from Razer and fkashall and now it won't boot to recovery download or system . It just hangs at the logo screen for better part of 2 hours now so it's not a waiting game .. any luck in fixing yours?

Best regards

I have the same problem, but I wasn't updating or installed any new app. I was just ordering food from an app and then all of a sudden my phone restared and got stuck in a bootloop.
I reflashed the stock rom, over and over, slot a or slot b, hoping that would fix it somehow... it's just stuck there now. I could go into download mode and recovery mode. but, it's only until there.
now it's bootloop until it gets into download mode...

I could fix it. After flashing (even Android Pi) you have to do a factory reset.
IMPORTANT: THE FACTORY RESET IN TWRP DOES NOT WORK. So you have to flash the boot-sector in your system partition with the stock boot.img and reset to STOCK RECOVERY by typing "fastboot reboot" and pressing the vol-up button. Once in stock recovery, do a factory reset and return to bootloader. Now you can flash the boot.partition with twrp boot.img, install in recovery the stock boot.img, install the twrp-installer.zip and reboot to system. The bootlogo will not stuck anymore.
I hope, I could help you. Do not forget to backup before trying.

sry for my bad english

Phone keeps Crashing on Boot animation, No iMEI, Wifi, Bluetooth. Restart loop.

This a bit of a long short story, so please bear with me for a while.
I first unblocked my Lenovo K5 Vibe Plus a6020a46 (India) in 2017 and using TWRP I had flashed the AEX Oreo v5.7 ROM. It was a great change and everything else was working fine for a long time.
Fast forward to 2020, I felt the phone was slowing down so I clean flashed AEX Pie v6.7 using TWRP, the ROM worked slick but after some time weird problems started to rise. Here's the chronology of what happened:
1. While using some apps the phone used to freeze, then shutdown. A restart would solve the problem for a while. But the lag used to remain.
2. The same problem repeated after a while but this time the phone went into bootloop.
3. I wiped cache, tried other solutions but nothing worked out so I reflashed the same ROM after a clean wipe. Phone worked fine for a week but then slowed down and finally crashed (This happened 2 times.)
4. After a week it was different, this time the boot animation would get stuck, then the phone would crash. So I reflashed again but when I booted up the phone there was no SIM service, no iMEi, No Wifi, No IP, Bluetooth.
5. I thought this AEX Pie ROM to be a problem so I flashed Arrow OS, Paranoid OS, AEX Oreo version, AEX 10 version but the problem remained: The phone would boot, boot animation stuck, and the phone would crash. This loop is where I am now.
I followed THIS GUIDE and tried reverting back to Official Stock ROM using QFIL. The flash was successful but the phone wouldn't bootup and went into a restart loop.
Here are some more important details:
1. The recovery mode is working fine. I can flash and wipe but I sometimes get the error of "Unable to mount" on Data, System and Cache partition which is solved with a format.
2. I can also get into Fastboot mode, EDL mode for QFIL flash.
3. I can also view all files and folders from TWRP Filemanager.
TLDR; Phone keeps crashing on boot, reverting to stock ROM also leads to restart loop, the phone shows no SIM, Wifi, iMEi, IP, etc. Tried wipe, clean flash, format which is successful but the problem remains. HELP!
"4. After a week it was different, this time the boot animation would get stuck, then the phone would crash. So I reflashed again but when I booted up the phone there was no SIM service, no iMEi, No Wifi, No IP, Bluetooth."
This is caused by bad ROM flashing ( when your flash wasn't entirely successful). You can fix this by reflashing. This could also happen if you downgraded, so go back to the version uou were on and see if this did it. You can fix IMEI with root if you want, I saw a thread for another phone: https://forum.xda-developers.com/g5-plus/how-to/fix-persist-resolve-imei0-explanation-t3825147 see if this could help.
"Animation Stuck"
This could be a problem with the ROM and data/cache, try factory resetting. Otherwise, it is also a problem with the ROM
In any case, I would redownload and reflash Stock ROM again and see if it still happens.

[SOLVED] Bootloop after flashing IMEI qcn file, caught in vicious circle

/EDIT:
Alright, the thread can be closed. I somehow managed it.
In case someone faces the same issue, I used twrp to dd the sdf files back on the phone which stopped the reboots. After that, just wiped and formatted everything again and reinstalled the ROM.
Hello guys,
I hope you can help me with this issue since I've tried everything I know to fix this problem.
The plan:
Unlocking bootloader, installing TWRP and xiaomi.eu ROM on a new device.
Changing its IMEI with QPTS/QFIL afterwards.
What happened:
Unlocked successfully. Installed TWRP, xiaomi.eu ROM and Magisk.
After pulling the QCN backup and editing the file I pushed it back to the phone what seemed to work.
After rebooting, I noticed that the phone rebooted 5 seconds after showing me the "Enter PIN" screen.
Booted up again and the same thing happened.
I booted into TWRP, wiped and formatted "data", installed the ROM again. The phone started up normally and there was no reboot.
I went back to TWRP and flashed Magisk, the phone crashed again and everytime I boot it up, it immediately reboots after some seconds. Installing Magisk somehow triggers the phone to reboot on its own.
I thought to start over, flashed everything from stock using Mi Flash Tool and the newest China Rom.
After starting up the phone, the issue still exists. This time with this rom there is no difference between installing Magisk or not, the phone always reboots after showing up the miui welcome/setup screen.
Current situation:
The phone boots up Android, reboots after some seconds and goes into fastboot automatically. After the fastboot timeout it again reboots automatically, goes into the OS and crashes again and on and on.
No matter what I do, I can't keep the phone from rebooting.
And since I can't flash Magisk, I have no root.
This means that I can not use root to put the phone into diag mode to restore the original qcn file.
I have backups of the EFS partition and also sdf7/8/9/10 files. I just don't know how to restore them given the current situation.
Thank you very much in advance for your support!
Cheers

Self-bricked Lenovo P2. Can't load or flash TWRP

My wife used a Lenovo P2a42. The phone has bootloader unlocked, she used either stock firmware or deodexed stock firmware ver. 244. A few days ago, she put a working phone in her bag, and when she took it out, all she saw was the startup logo. The phone was in this state for over an hour, it was reset by long pressing the POWER button. The phone now has a bootloop. Unable to enter Recovery, only fastboot is available. ADB is not working.
I tried to re-flash the firmware by the command line - the files upload correctly, but after the reset the phone still has a bootloop. I also uploaded the TWRP file both as recovery - everything is fine each time, but after rebooting the phone does not enter TWRP, but still has a bootloop. What's the problem? What else can I do or check? I have a full phone backup with TWRP, but cannot restart TWRP to recover my data. Maybe the partition format is incorrect or the memory is corrupted?
These problems r common in lenovo mobiles. try booting to download mode and install stock firmware using odin.

Unlocked bootloader - boot loop after trying to put stock firmware back on

My telephone keeps booting to fastboot after trying to update TWRP.
I am trying to restore the original ROM (apollo_eea_global_images_V12.5.12.0.RJDEUXM_20220208.0000.00_11.0_eea) and I can get the rom installed through fastboot but the phone enters a boot loop cycle. It starts up, vibrates shortly then reboots.
If i press volume up it goes into the original recovery menu. I have tried clearing everything and even entering safe mode but the phone will not boot.
Am i screwed?
Thanks in advance.
I installed the Pixel Experience recovery and side-loaded the zip and at least have a working OS.
I must be doing something wrong with the stock mi10t
Now i sided the miui zip and its working agian. I think i have misunderstood the procedure. I thought you only need to install the rom with flashboot and that was it.
