Go back to previous version of ROM to fix Miracast issue? - Moto Z4 Questions & Answers

Is it possible to go back to previous versions of the Stock ROM on the Moto Z4?
My Wi-Fi Direct (Miracast) connection stopped working and I suspect it's because of an update.

Wow, thanks, that was such a quick response!
That seems like the exact answer to my question, but in light of all the warnings about the risks that seem pretty scary, I think I'm going to not do it for now.
Instead, I'll just search away about the Miracast problem itself, though I suspect I won't be able to fix something that seems to be such low-level functionality.
Thank you, sir.

[Q] No 4.4.3 Update UK 8GB Eu model

Hi, has everyone received their 4.4.3 update as I'm still waiting to receive mine also some are getting the 4.4.4 now so it seems a bit strange! Also does anyone know if I can update manually?
Thanks

you don't want 4.4.3 and they stopped it anyway, 4.4.4 has not been rolled out in the uk yet as far as i can tell from these forums.

It's far more complicated than that.For the moment the UK Moto Gs are still on 4.4.2 (which is actually a good thing).
Even if it comes out these days, I won't be updating, until the don't release a bugfix to patch all the issues with 4.4.4

Can tell you only few that I find significant. But the full list is quite extensive.
OTG doesn't work at all.
The proximity sensor gets stuck/ doesn't react while incall.
Loss of Wi-Fi and 3G signal for no reason.
Your device emmc gets re-petitioned and may get bricked.
Some poorly written, but useful apps doesn't run
Miracast doesn't work from time to time.
The vast majority of issues are due to upgrading via OTA update. I've Fastboot flashed the 4.4.3 US firmware image and had none of these problems.

In which sense bud? I mean, when i flashed ota for kk over jb i haven't had any problem. Do you mean in this sense?
I'm only suggesting if people are having issues; download the full firmware, wipe phone and flash via fastboot.

True. But that image does work perfectly fine on a UK / EU XT1032.

OPO week signal, fluctuating signal...Chinese Version

Hello, I know there is another thread about this but couldn't find what I need. I just got my OPO from China yesterday and flashed CM11s. It works good but the signal is week and keeps going up and down. Like good signal and then almost nothing a second later. What can I do?
Would flashing another ROM maybe fix this? (Like regular cm11).

OK. Great. Thanks. Would you mind explaining this to me...I'm a newbie. So when I flashed cm11s...this doesn't effect my modem, I have to do this seperatly?
Which version of 11S do you have? I mean...25R, 30 or latest 33R.
33R has well enough modem but...it maybe doesn't work for your country.
First... You should to unlock bootloader, then install custom recovery. After that you will be able to install alternative modem from custom recovery.
You can read all information about that in the nearby topics.

Anything you do flash on XDA is risky though. Its a chance you take just loading the web page.
But yeah, be very careful if you do unlock it. It's not hard but requires a lot of reading and paying attention

I dınt think its too risky.I play around the bands and nothing bad happened .Its worth to try,even i could not unlock my 2g bands.But somebody says the signal is much better now.

I turned the modems I have into flashable zips and posted them.

Assume NO - why do you want to flash it anyways? You will not find anything fixed, the problems lie in the bootloader.

I'm having signal drop problem with JB and KK modems so I thought i could give a try to 30F to see if it is fixed.
Tried on latest bliss for d800, booted fine but only sensor that works seems to be GPS. Everything else doesn't for me. Flashed back to previous and all is good.

30f but I am on jb sourced ROM so naturally that's expected
Installed 30f in my wife's D800 and everything so far so good. She had some signal problems with GPS nav, lets see if this fixes it. Thanks
Flashed 30f on my d800 running the latest PA (MikeCriggs' 5.1.1 builds). I couldn't get rotation to work. I just want to confirm that it's not patched yet.
I may or may not have a hardware problem, I'm getting intermittent GPS lock loss.
Jellybean: d80010d & d80010o LTE, rotation works, GPS losses lock
Kitkat: d80020c & d80020y , LTE, no rotation and GPS losses lock
Lollipop: d80030f, every 5 seconds, complete loss of radio, rotation, GPS losses lock
I'm on 06/12 nightly, D800, formatted/wiped, gapps-lp-20141212-signed, everything else works. (Same results on older nightlies).
I hate to say this, but is my only option at this point, to flash back to stock and see the the GPS loss follows the hardware and not the roms?
Thanks,
Dylan
Well damn it all to hell. I flashed back to v10d tot stock rom and my GPS still doesn't lock like it should. So it's a hardware problem. That sucks as I love this G2/D800. At least I was able to eliminate the radios as the cause.

Just squeezing (very hard squeeze) the upper right of my G2 screen got my GPS to start locking. So, soon, I'll use my finger nail to open up the G2 and fix the GPS sensor connector. Thanks !
Can anyone tell me which modem and bootloader I need to run a 5.1.1 aosp based ROM on my d800 please? I've been scouring all over xda and have been out of the loop for almost a year. Just dug this g2 out a few days ago while I wait for parts to arrive for my more recent phone. Sorry if this is OT, but any help would be greatly appreciated. Thanks
hello guys need help, how to go back to stock specially to d8002y i'm currently on custom rom [simple rom] because i want to update to 30f which requires to be on d80020y. from this thread >> http://forum.xda-developers.com/att-g2/general/update-to-stock-lolipop-d80030f-root-t3084081
Correct me if I'm wrong about the GPS, but I believe it gets geographical lockon hints from WiFi/3g data/radio towers. If you've enabled everything regarding location. Use fastergps and set your closest NTP server through fastergps. This was a more common problem on older Android phones which were modded or imported.

Just choose a Lollipop (LP) modem and bootloader, most of the regional things just optimise it for common basebands for telco companies in that area.
Although I suggest going with AICP Marshmallow + minimal slim gapps. For the best performance and battery life. Launcher wise a customised Nova Premium (increase icon size etc) + the free Polycon icon pack, for the best user experience and design.
Question for OP
I have a stock LG G2 that has the OTA LP 5.0.2 Build LRX22G Kernel 3.4.0
When I upgrade to CM13 do I need to reflash the radios or change the bootloader so I get all my radios and sensors working?
When I first got the phone it was JB then OTA to KK on the same day, then like everyone else, I had the forced OTA to LP WHICH I HATE!!! I loved my home screen rotation with JB and Kitkat.
If i Could I would have this thing imaged back to KK and lock out OTA so it never changes again. BUT I have taken this phone to Tmobile now and they tell me that TMO OTA will not affect my phone because it wasn't a TMO model.

Help Y01 tablet ,still working previous owner had issued recall

I currently have a shield tablet Y01 ,its on stock Nougat (5.1 ota update). not rooted or bootloader unlocked
Previous owner did the recall and new tablet will be here in 3-4 weeks , so tablet is currently working
What can I do to make sure this isnt killed ?
Need a n00b guide really as havent flashed anything since a htc desire
no one ??
Root, then use a root explorer to delete TegraOTA.apk.
Root guide is here: https://forum.xda-developers.com/showthread.php?t=2399737
TegraOTA guide is here: https://forum.xda-developers.com/shield-tablet/general/kill-kill-switch-shield-tablet-xx-t3179489
Alternatively, you can flash any custom ROM. They will prevent the tablet from updating as well.
So... The old killswitch-killer still works on Nougat? I could flash the nvidia stock, delete the TegraOTA.apk and go on with the newest official nvidia version?

BTW, newest FullOTA (WiFi) is available directly from nvidia servers, as An Droid mentions here: http://ota-downloads.nvidia.com/ota...-full_ota-1928188_850.6612.20170219210839.zip
Hello,
Sorry for up this last thread, but I'm in the same position that the OP.
I have a pyro tablet on stock Nougat (the original owner did the recall) and it is still working (for 3 weeks). Is the kill switch disallowed for Nougat?
Should I unlock the bootloader and root it for remove the TegraOTA?
Thank you!
Yes.

Any possible future support from OpenKirin?

So, OpenKirin already supports a handful of phones equipped with Kirin 659, is possible that in the future our MediaPad T5 will be added to the compatible devices? There's any interest in this device by the team?

It's just an academy question
There is no doubt in the fact that unlocking the bootloader is the first step needed to flash Custom ROM. As far I know, there is no way to get unlocking code for MediaPad T5.
Well, I read in this forum that unlock the bootloader is possible with the "BLK method", but this requires opening the device and pay a third-party for the code.
I honestly have no idea about what this BLK actually is or why you need to open the back of the tablet.
alex5230white said:

Because you need disconnect the battery and short test point. You also need two things to flash with testpoint - Board firmware ("DC-Phoenix" or "easyfirmware.com" - paid services) and Huawei flash tools "IDT" .
Unfortunately, Board firmware for MediaPad T5 is not available (not supported device).
So it's just an academic question again

It is not officially supported, however, since it is a kirin 659 with emiui 8 openkirin team says it should work.
I've tried a couple of their builds, and only lineageOS16 seems to be booting among those.
It's working well, just disable HW overlays in the dev options to get rid of the annoying blur and it's all good.

there is this thread describing the experience:
- camera does not work
- some problems with Netflix DRM
* must install an older version + some system mod
* (haven't tried it) use third party app like Kodi with Netflix addon?
- must install custom Audio EQ app and disable the included AudioFX
- some 5GHz channels might not work ( must use channel 44 for example)
