What is the safest method to downgrade to previous ROM version?
I am having a lot of issues with connectivity. I verified that APN settings are correct. I am able to connect to 4G network but when I try to make a phone call the phone is switching back to 3G.
I used to have VoLTE icon and clarity was fantastic , aftert the latest update I am unable to place calls on 4G network and quality of sound on 3G network is very poor.

I also having problems with connection signal. Before update I had full bar 4G LTE. Now I have 2 bars of 3G or sometimes 4G but internet is very laggy.

I tried the APN settings mentioned earlier in a thread by bencebacsi (Name: IMS, APN: ims, APN type: ims, APN protocol: IPv4/IPv6, APN roaming protocol: APN protocol: IPv4/IPv6)- phone was not able to place a call with those settings at all so I switched it back to the APN settings provided by my carrier.

I would like to downgrade my version and go back to previous version but I was not able to find the procedure on the forum. I see the postings on UPGRADING manually but found no information on DOWN grading. Can I reflash older ROM over newer one?

Right now I have V1.3 but I would like to go back to V1.1.

Please advice on what can be done.

Thank you.

The IMS profile is already there and I check the IMS setting too. It is as same as you mentioned.

VoWiFi is important if my carrier signal is not covered. Also, I can make or receive call normally with WIFI when I am in oversea too. Why it is not important?

Your issue is specific on your side, we can't reproduce it and not a mass of users have reported it. Try to reset the wireless settings or the phone to factory data defaults. You can downgrade/upgrade your phone with SP Flash Tool to any version but after flashing an older version, you shall not be able to reboot your phone without a factory data reset.

I didn't say that nobody needs VoWiFi but I'm pretty sure, less than 1% of all users need it and less than 10% would even be able to use it. Fortunately, there are third party apps to help you out.

Hi,

I'm on version 1.2. Phone didn't find any update. Looking here I see that rar version is only for v1.1.

So for these that have v1.2, the only possibility is to use SP Flash tool or it will be delivered via OTA?

There's nothing to fix about that. Your issue is related either to your specific device (flash with SPFT in firmware upgrade mode) or to your mobile carrier/subscription.

Yeah, that's what I meant. Sorry for that.

Anyways, I saw that Wyroczen over at XDA actually compiled a RAW Enabler for the RN8P. I flashed it just to see...no luck of course. But would something like this be possible for the US5P?

On a side note, GCam Go seems to work, albeit in a limited state (No HDR or Nightmode yet). Hopefully in the future!

Good day.
After the last update, did I just notice or are there other users that the battery charge just flies - even in standby mode? If before, with moderate use, the battery lasted for 5-7 days, now almost without using the phone the battery dies in 3-4 days. What is that supposed to mean? What have you done with your phone's power consumption?
