Service issues after upgrading to 5.0

I upgraded from a stock rooted 4.4.2 to the OTA 5.0 using the ROM that was rooted. Some apps for my smart watch don't work in 5.0 yet, so I went TWRP and restored my backup. After booting, the phone will not get any service at all. It shows it's searching for service then gives a red "x" then starts searching again. This is process that just keeps going. I flashed the stock .tot file using the LG flash tool to get the phone completely back to stock. After doing so, the radio still won't get service. I then applied the OTA push of 5.0. After 5.0 was installed, the radio gets service without any issues. I used the LG flash tool again to go back to 4.4.2 stock and same issue; no service. Updated again to 5.0, and I get service. Any ideas on what's happening here? Is it the firmware for the radio that's having issues?
I was able to fix this by playing with the APN settings and it was able to get service, but no data. I then went back to the default t-mobile APN setting and now it works.
Same Issue
After using lg update tool to go to new 5.0 update, I put twrp back on and flashed cm12 and bliss pop rom on mine and service 100% drops out and only came back after a battery pull or a reboot, e tried to re-install roms on both and after having the same issue with the roms i tried a custom kernel issue went away and then came back, so i haven't tried AOSP since the t mobile said they'd send me another brand new phone ....but once i put everything back to OEM using the lg tool it's been 100% working again with no issues... i will try AOSP when the new phone gets here,, im thinking its kernel related
You need the new modem, boot loader, and boot images. You can't simply just flash a ROM unless all 4 (system included) is packaged as so

Android 10 Update/Upgrade a705mn/ds Variant

Hi,
Is there another way to flash the firmware of A70 without using ODIN. I've updated my A70 yesterday via OTA trough ANDROID 10. It Updated successfully but when the phone restarts the phone no longer charges and can't recognize charging. Battery Icon shows 0% and keeps rebooting by itself.
I've already try clearing the cache/ reset to factory via recovery. same issue.
Try to download official firmware from Samsung. Flash successfully via ODIN. Still Same Issue (Android 10)
Try to Downgrade Official Firmware (Android 9) flash trough ODIN And still The Same.
Any Help Will Do. Thanks
By the way my Phone is a A705mn/ds (XTC Firmware)
Solution Found.
I manage to recover the device. using the latest ODIN (version 3.13.1) downgrade to XTC-A705MNXXU5ATA3-20200211101340 (Last Android 9 Update for A70 (January 2020 Patch)). Booted up normally.
But the weird thing is when I try to FLASH the Android 10 Firmware using ODIN (A705MNXXU5BTC2_CL17976949_QB29690579_REV00) the problem happens again. Auto Reboot, Battery Not Recognize, Charging Port Not Charging. Can't Even Use it for a couple of minutes.
I think there is a problem with the Android 10 Update on a705mn/ds variant. tried and tested via OTA and Manual Upgrade ODIN Flash. =(
By the way in order for you guys to stop the Update Just go to
Settings > Software Update > Disable Auto-Download over WIFI
then go back to
Settings > Biometric and Security > Other Security Settings > Disable Security Policy Update
then go back to
Settings > About Phone > Software Info > Tap Build Number 7 times (For Developer Option) if not done yet
then go back to
Settings > Developer Option > Turn off Auto Update System
This should STOP the update process
Hope this helps!
P.S. If you have an a705mn/ds variant give some feedback did you successfully update your device on Android 10?
Hey. I have SM-A705MN and the Android 10 update is working well. The only issue so far is minor. Task Changer interferes with the ability to swipe down for notifications unless turned off/on (problem arises after reboot).
I did foolishly try to install TWRP and after the second failed attempt i could not restore firmware in (any version) Odin. Finally after messing with Heimdall and getting odd responses i flashed bl, restarted Odin and flashed all 4 parts.
After that i patched AP in Magisk. I then flashed all four files in Odin with HOME csc and it looped so i went to recovery and after a factory reset i have root with the button start method.

I'm going to tweak the csc files now (after a run through the decoder). I'll post whatever tweaks i use that work if you plan on rooting.
it's always preferable to use the latest Odin , your is v3.13.1
here it is : Odin v3.14.1

Hello I'm currently experiencing random reboot on my device (SM-A705MN/DS). It started last February 27, 2021 when i download patch update for Android 10. Prior to this update I'm already on Android 10 and everything seems to work fine back then. However this last Android 10 update cause this strange behavior. The phone will freeze then goes off and the it will boot again. After reboot it will work for say 30secs to a minute then it will freeze again and goes off.. It goes to this process multiple times until it gets hot on the upper half portion of the phone. What i do is let it rest and cool for good 1 hour or more and then when i reboot it manually it will work fine for the rest of the day. After nearly 24hrs or up to 36hrs it will work well. Until it resets itself and do the multiple restart again. I experienced this on a daily basis now even after upgrading to Android 11.
Do you think downgrading to Android 9 will resolve this issue? I already visited Samsung Service Center and initially they thought it was already fixed. So i did not left the service center immediately and test the unit first. I see that my unit is still Android 10 and factory reseted. After quite some time it reboots randomly. That's when the Samsung service tech concluded that it's a malfunctioning circuit board. However i am not quite convinced since my phone works perfectly and the issue only manifested after that particular update and the proceeding ones.
Does downgrading to Android 9 and upgrading straight to Android 11 can prevent this issue. I hope you could help me. By the way Noypi here. I supposed Noypi ka din coz it's obvious base on your username. hehe

How to restore stock rom on XT1789-03 Sprint?

Hi
I bought this phone few months ago. It comes with Android 9 whereas officially XT1789-03 only has Android 8. I installed LineageOS 17.1. It was working great but from last 2 weeks the phone started randomly rebooting. So today I tried to update it using the recovery (Dirty Flash). After that phone was rebooting again and again at Lineage logo. So I factory reset and clean flash the lineageos 17.1 but it is not working. Used different techniques but not working (Used TWRP also). Now I want to go back to stock firmware or to stock Android 9. But I have read here that I will loose my imei and baseband. So what is the proper way to flash stock firmware or stock Android 9 (Preferably Andriod 9)?
Please help me.

Do I really need to flash the stack ROM , is that the only option I have ?
