[OnePlus 3 Questions & Answers] NeroTheDawn:
Hey, after updating from CB1 to Oxygen OS 9.0.2 i can't access the device (OP3) via fastboot anymore. I have installed all needed drivers and adb is working as it should.

What is strange is, that my device is always shown just as "Android " with a "!" next to it.

Device has been updated via official full update (Downloaded w oxygen downloader - full update)

I have already tried to reinstall the device in the device manager

I have completely reinstalled all ADB/USB drivers

USB debugging is enabled

Has anymone having the same issues? Under CB1, everything was fine...
[OnePlus 3 Questions & Answers] bartovitc:
Have you tried different USB ports? Even other PC's?

I had the same issue, but managed to get it working on another laptop.
[OnePlus 3 Questions & Answers] NeroTheDawn:
It was working on a linux based system started from a usb stick in the end, but using the same computer. After long time of research I found out, that it is a problem caused by windows 10, not wanting to install the right drivers. Aparently you only have few options to fix this. But as it works with a usb linux system, I have a "fix" now :)
[OnePlus 3 Questions & Answers] therightperson_630:
Sounds like ADB/Fastboot drivers aren't installing properly. You have looked up the right way to install those drivers on Windows 10 haven't you? by disabling driver signing enforcement:

https://ph.answers.acer.com/app/ans...windows-10:-disable-signed-driver-enforcement

ADB/Fastboot works for me and a lot of other people.

It's not a OP3 problem.

Good luck.
[OnePlus 3 Questions & Answers] NeroTheDawn:
Check my last reply. I know that its not a OnePlus specific problem, but when I faced this problem the first time, it was right after the Update to pie - which was a coincidence.

Thanks for the advice with the driver signing enforcement, I will try that!
[Huawei Mate 20 Pro Questions & Answers] BlueMeany68:
I've recently started getting notification from "Phone" saying Selected service is unavailable (see screenshot). I know there is no network, as its a network blackspot but I've never received these notifications before!

I've been into Notification settings for "Phone" but there are so many options. I've turned them all off and that seemed to clear but then I'm concerned might not get notifications when like I'm using my mobile phone what it is intended for!

Any suggestions as what to disable?

Thanks
[Huawei Mate 20 Pro Questions & Answers] oslo83:
Settings/Wireless and Network/Mobile Network/Carrier/ then choose Automatic selection
[Huawei Mate 20 Pro Questions & Answers] BlueMeany68:
Bizarre. I had all that set and was still showing the notification.

Changed it so I chose a specific network, then back to automatic, rebooted and it appears to have sorted. Will wait and see...

Thanks
[P8lite General] ghostmag:
Dear friendly xda-developers,

I did a factory reset and afterwards I wasn't able to select a region.

At first it asks me to select a language. After that I have to select a region, but when I press the "next"-Button it just blinks to show me it got pressed and does nothing.

It doesn't matter which language and region I select, none of them will work. And tried to factory reset again and the problem didn't change.

Any idea what I could do?

The phone is not rooted, nor did I do anything to change something on the phone. I just did the factory reset via booting the phone while holding Volume Up + Power Button and then selecting a factory reset.

In case that information helps: Before I did the factory reset I could't open the settings app. It didn't work when I selected it directly nor did it work when I was holding the symbols for example WLAN or bluetooth. The result of trying that was nothing.

I thought it might be a possibility to install stock firmware or stock OS again on the phone? But I couldn't find any guide on how to do that. Bootloader is locked and never was unlocked, so a custom ROM is probably not an option.

I really hope someone here can help me with that.

Kind regards
[P8lite General] D1stRU3T0R:
If you have open bootloader than flash personas mod, if not, try a factory reset again.
[P8lite General] ghostmag:
Bootloader is locked and factory resets won't help.
[P8lite General] D1stRU3T0R:
Hmm, isn't force update working? Put b638 on sdcard and install it from stock recovery.
[P8lite General] ghostmag:
I will try that. Do you have any guide for that?

And can I do that via fastboot instead? My SD card has only 2GB. If it only works with a SD Card, I will buy a bigger one.
[P8lite General] D1stRU3T0R:
I guess the rom is less than that. And idk with fastboot, you need unlocked bootloader for that afaik.
[P8lite General] ghostmag:
I borrowed a SD Card and it all works fine now. Thank you.
[Nexus 7 (2013) Q&A] IgNuReNt:
Good morning guys.

I'm not really new to this forum, I've known you for years and I've always followed you for small "mods" or particular problems that I had over time with my devices.

I apologize, but I would like to ask you for help because I have big problems with an ASUS Nexus WiFi 32GB Tablet

Unfortunately, I can in no way connect it to the PC in order to install any rom (I wanted to install the rom stock). I tried everything, I even formatted an old PC and installed windows XP hoping for more compatibility (nostalgic).

The first time, I managed to install a ROM from TWRP recovery 2.8, enabling the USB-OTG and buying the appropriate cable, but then unfortunately, I wanted to try to change ROM and already I was there I wanted to update the recovery to 3.3 .1.0, but I must have been wrong to click somewhere in the recovery. I was convinced that the USB-OTG could always be enabled, so I had the security that I would always be able to install a S.O.

Now the S.O is no longer present in the device and from recovery I can no longer enable USB-OTG, and obviously in the device, no image is present that can help me, probably because I have eliminated everything with different wipes.

The PC in no way manages to see the device, whatever driver I try to install, it tells me that they have no information regarding the connected device, so I can't even use adb.

Please, help me, if needed, format a PC and install Linux or anything else I can use to resurrect this damn device.

Thank you so much for existing ...
[Nexus 7 (2013) Q&A] ichi-nii:
Hello, did you try to reboot your tab in bootloader mode, and then install stock factory image from Asus? Maybe After that you will be able to reinstall twrp and custom rom you want... Your tab is unlocked? Did you try the wugfresh tool? Good luck
[Nexus 7 (2013) Q&A] IgNuReNt:
Thanks for the reply ichi-nii, I tried to reboot the device in bootloader mode (The menu with the open heart robot, Fastboot Mode, right?), Even if it doesn't give me many options, I can only choose whether to Turn off the device, Start it in Recovery (TWRP) or restart the Bootloader, nothing more, and from here I can't install anything anyway.

I believe the device is unlocked, or at least it was, and Fastboot tells me that it is unlocked, so ...

To use the Wugfresh tool, if I didn't err I have to be able to connect this Nexus to the PC and make it see it, but as I said ... No driver allows me to recognize this device from the PC ...

I don't know what to do ...

Isn't there a TWRP terminal way to do something? Some commands that can re-enable the USB-OTG ...

I think I inadvertently (because I didn't know what I was going towards) SELinux enabled, it was after this that the USB-OTG didn't work anymore (I think) ...
[Nexus 7 (2013) Q&A] ichi-nii:
Sorry for you bro, so you tell me even in bootloader mode , the tab is not recognized ? Maybe try to connect it when you are in twrp, And another one thing, maybe try another usb port or cable... About otg I can't help you , maybe your connector is broken? Did you try with windows 7 or linux( just to send files to sdcard)

edit: I just try to connect my tab (twrp mode on the screen) to my computer with kali Linux and I Can access to sdcard on the tab
[Nexus 7 (2013) Q&A] IgNuReNt:
Thank you so much for your help!

I tried to connect the device, both from TWRP and from Fastoboot mode but it is not recognized by Windows ... (Both Windows XP, Windows 7 and Windows 10) I tried to change USB ports and I also tried to change the cable, but nothing ...

The OTG cable is new, I used it on this device and it worked perfectly, I tried it on another device and it works, so the cable is ok, I must have done some **** myself.

Sending any file to the device is just what I'm desperately trying to do, I don't care how, I'm interested in doing it and fixing the damn thing.

If you tell me that your computer with Kali Linux sees it and you can access the memory, I try immediately.

Thank you so much !!

I'm not at all an expert on Linux, how does it work in this case? From Linux terminal? do I have to send commands? Or is it seen as a folder? ....

Forgive my humble ignorance ...
[Nexus 7 (2013) Q&A] ichi-nii:
? I'm not an expert too? just install any linux with graphic interface then open the file manager , I did this with kali just because I have it on an old computer.

Good luck
[Nexus 7 (2013) Q&A] IgNuReNt:
I have to thank you for the help, from Linux I can easily see the device, I managed to insert in the internal memory the rom that I had previously installed ... so I took a big step forward! Unfortunately the misfortune haunts me and the recovery doesn't want to know to install that damn rom. I had to fall back on a Slimroms that I found here on the forum, but I'm not exactly where I want to be. I would like to be able to install my ROM or at most something more complete and updated. Now I try to install the GApps so that I can install some apps that allow me to permanently disable SELinux, then try again to Flash my rom ...

I do not know how to thank you! You have been very helpful.
[Nexus 7 (2013) Q&A] ichi-nii:
Congratulations, like you said it's a big step. Do you use the last twrp? Maybe the problem comes from that...
[Nexus 7 (2013) Q&A] IgNuReNt:
I updated the TWRP to 3.3.1.0, I think it is quite up to date, but it is strange that this is so, because from OTG I installed it quietly without problems ... I am convinced that SELinux blocks something ...

I also tried to check the zip file before installation and it gives me an error, it can't install ...

I'm going crazy ... but at least now I have the chance to do tests!
[Nexus 7 (2013) Q&A] ichi-nii:
And now Can you connect the tab to your computer (with windows this Time) If yes you can try install the rom you want from the wugfresh tool?
[Nexus 7 (2013) Q&A] IgNuReNt:
My dear friend! You are an ace, a beast! It was only thanks to you that I was able to solve my problem. Thank you very much, now there is a little 7-year-old who can come back and have fun with this Nexus 7, and of course he also thanks you very much.

I'll tell you briefly how I had to move and the problems I encountered and how I solved it step by step, so that if it happens to someone else, it may have a path to follow eventually.

I was screwed, after I managed to copy the stock image from flash to Kali-Linux inside the Nexus 7, because that damned TWRP crashed during installation without giving me a reason, I had to restart the tablet and that's it; from linux, same speech with ADB Sideload, did not complete the installation.

So I tried to Flashare a custom image, Slimrom that gave me only problems right away, I couldn't touch anything that gave error (but it was installed .. so I was still hoping).

So I tried to flash my damned stock rom directly from Fastboot, but it gave me a thousand mistakes of every kind, from there I suspected that there was something wrong with the file system or the partitions ... something must have messed up something , it was not possible that I could not install any roms anymore, not even the wipe worked, there was something strange, I thought of starting from the base.

So from recovery I found the function that allows you to change File System in the various partitions, so one by one I restored F2FS, the Wipe worked magically, the road was the right one.

I start with the installation of the Stock Rom ... but nothing, errors concerning the lack of files or information (now unfortunately I don't remember in detail)

Reading on the forum, I realized that it could be a common problem and that you could flash the individual files contained in the "stock.img" file that I had downloaded, even individually. So I extracted the archive of the downloaded stockrom, extracted the same .img file inside it, I found myself with all those files.img (boot.img / recovery.img / userdata.img etc etc) at that point I have them flash them one by one with the special fastboot commands.

eeeeeeeeeeeeeeeeeeeee

Taaaaaaaaaaakkkkk

Now it finally starts, it works !!!!!

All this, thanks to you, with that idea of ​​connecting it to linux you gave me hope and it worked !!

I am Italian, from Rimini, if you ever happen in Italy you have a paid fish dinner !!!!!

Thanks again!!!!
[Nexus 7 (2013) Q&A] ichi-nii:

[Nexus 7 (2013) Q&A] seth.j.near@gmail.com:

[Sony Xperia 1 Questions & Answers] hpsauce37:
Had my x1 for a couple of days now and lots to like about it however I have noticed that it seems to have a very weak phone signal reception.

I am on three in the UK and in the normal areas I travel I have never noticed an issue on my other phones with it struggling to hold on to signal bars.

Anyone else have this?
[Sony Xperia 1 Questions & Answers] VeixES:
Signal bars mean absolutely nothing. Many oem even show full bars even when there is actually no signal.

Better install cellmapper app that will exactly show and record the signal where you travel.

Also, do you have 3uk volte working?(calls over 4g network)
[Sony Xperia 1 Questions & Answers] hpsauce37:
Well all I can say is that I live less than a mile from the nearest mast and would nearly always have full signal bars on other phones yet on this phone it drops on and off 1 bar.

I will download the app you mentioned and see what that shows
[Sony Xperia 1 Questions & Answers] andybg40:
I've had this problem with numerous Sony phones over the years, always poor signal compared to Sammy's, Pixel's and iPhones that I've had. Same issue with the X1 I have now, always on WiFi calling and no signal, my Pixel 3 XL would be happily sitting on 4G.
[Sony Xperia 1 Questions & Answers] hpsauce37:
Glad it's not just me then.

I do remember having this issue on a previous Sony phone also but can remember the model now. It's been a long time since I had a Sony but thought this one was going to tick every box which it almost does apart from having reliable signal reception which is really should be a must!

Is there anyway they can improve this with software of are we stuck with it due to hardware issues?

I'm in my 14 days returns periods at the moment and like everything about this phone apart from what it should do first and foremost
[Sony Xperia 1 Questions & Answers] ramheer:
I am having the same problem, I'm on EE and my LTE keeps dropping from 4 bar's to 1 bar then nothing which causes me to lose data connection. It then jumps to 4 bar's again and then repeats this over and over. This is happening at home where I always have full reception. I have tested my sim in 5 different phones all have full reception and don't lose connection only my Xperia 1 does! Any help would be appreciated.
[Sony Xperia 1 Questions & Answers] jackfrost3821:
Same problem for me. I switched my SIM from Galaxy S8 to X1. S8 has 4 to 5 bars while X1 struggles with getting one bar at home.
[Sony Xperia 1 Questions & Answers] VeixES:
Ffs... The bars mean nothing. Sony phones take into consideration RSRQ(signal quality) and SINR(s noise) values of the signal. Other oem don't. The actual signal power RSRP (do not confuse it with bars) is same or better on Sony.

Xperia 1 has most advanced modem and antenna setup of any 4g phone. 4x4 mimo even on low bands (first to have it).

3uk and ee are special in the sense that they need phone to support volte to get access to their low band spectrum(band 20).

So make sure you have volte aka 4g calling enabled and check with apps like Netmonster or Cellmapper the band and RSRP of the signal. Then compare it with other phones at the same place.
[Sony Xperia 1 Questions & Answers] hpsauce37:
If it's as simple as that why is it not enabled on this phone already?

I think what you seem to be over looking is the fact that I and others here have said that yes the bars are lower than other phones and flutter slot but also to the point where they drop completely and give no reception at all. A situation not faced on other phones.

Can you explain how we enable this missing band so that the phone can provide a more reliable/stable reception
[Sony Xperia 1 Questions & Answers] VeixES:
Does your phone have 3uk volte(4g calling) enabled? Phone should stay in 4g during call. If not then you are out of luck.

ee users can install EE firmware to get Volte working if it's not already . newflasher on xda helps to change firmware.

And please compare signals with abovementioned apps.
[Sony Xperia 1 Questions & Answers] charlatan01:
If you're having signal drops / dropped phone calls etc... I get it. But Sony is historically notorious for showing lower signals than others on those bars. However, as stated, the bars are pretty meaningless. I've owned many Sony's, and while the bars are lower (sometimes all empty), I still have signal in all the places I should. YMMV.
[Sony Xperia 1 Questions & Answers] hpsauce37:
I don't honestly know. My phone was purchased sim free from carphone warehouse and I use it on 3 network. The phone just set itself up. How would I check this? Is it something listed under network settings?

It's so frustrating as I'm really loving a lot about this phone but just want it to be comparable at least with my other phones I've used with call reception
[Sony Xperia 1 Questions & Answers] XSIIS:
those who are having signal problem, are you using EE network?

I saw lots of people with EE reporting this issue on official sony forum.
[Sony Xperia 1 Questions & Answers] marra2:
Got mine yesterday from Vodafone and signal is perfect !
[Sony Xperia 1 Questions & Answers] ramheer:
Yes
[Sony Xperia 1 Questions & Answers] decomposed:
I also have only 1 bar... Orange.
[Sony Xperia 1 Questions & Answers] VeixES:
If you are EE UK user, then you need EE firmware on your Xperia 1 to get best network compatibility(Volte and low band support because of it).

3UK users probably need also 3UK firmware but that does not seem to exist yet.

This weirdness of low band access is specific to two UK operators. Everywhere else the device is fully capable of best 4g experience.

[Sony Xperia 1 Questions & Answers] hpsauce37:
So for those of us on three network but purchased the phone sim free are stuck with the problem as three do not sell this handset themselves so unlikely to release any firmware for it.

That does not look good for me so I think I will need to return within my 14 days.

Shame.
[Sony Xperia 1 Questions & Answers] Chippy_boy:
There's definitely a network connectivity issue with the XP1 right now though. This seems to affect only XP1's on the EE network, which were *not* bought from EE direct, i.e. ones with stock firmware. (e.g. mine!)

The symptoms are that periodically, first the 4G symbol disappears, then the signal goes to zero and you've lost the internet. Then it reconnects back onto 4G again. Sometimes this repeats 3 or 4 times in succession. The whole thing takes from 5 seconds to maybe 30 seconds depending on how many re-tries.

You can go for maybe an our or so without a problem, or sometimes it happens like every 10 minutes.

And here's the key part: this happens wherever you are, even on a full strength signal. As far as I can make out, this affects ALL XP1s with stock firmware on EE. EE say it's a Sony problem. Sony say it's a network issue. So we are all stuck.

Does anyone know of a suitable network logging app, which will log 4G disconnects and signal loss, so we can provide evidence to EE and Sony?

More info here:

https://talk.sonymobile.com/t5/Xperia-1/Issue-with-network-dropping/td-p/1376332/highlight/false

(My phone is fine with a Vodafone sim. There's something specific to the phone firmware/config - timers, buffer sizes, packet sizes - whatever - and the EE network. But right now, on EE, it's unusable.)

[Sony Xperia 1 Questions & Answers] augie7107:
UK carrier
[Sony Xperia 1 Questions & Answers] Chippy_boy:
Latest OTA update on EE fixed the connectivity problem (dropped connections) and also provides WiFi calling and 4G calling even for stock firmware XP1':s. So I am very pleased.

However, a quick question regarding antennas: does the phone have only 1, or is there one for upload and one for download? Does anyone know?

The reason I ask is that I am getting amazing download speeds (300 Mbs or more on occasion), but my upload speeds at the same time are often like 4 Mbps. Seem incredibly unbalanced. I rarely see more than maybe 10M bps upload. It's MUCH slower than my old Pixel on Vodafone. Maybe this is just how it is with EE? I don't know
[Sony Xperia 1 Questions & Answers] decomposed:
It depends on carrier. So yes, most probably your new carrier has poorer upload speeds, remember upload costs more than download that is why most of the time it is slower.

I have Sony Xperia one bought directly from Sony store (vanilla) After the lastest update I had a problem with poor signal.. After using secret code *#*#4636#*#* I have changed lte/UMTS prl to LTE/WCDMA it resulted have a lot stronger and stable signal. ( EE UK user). Do not change in android prefered setting within system setting after that
[Sony Xperia 1 Questions & Answers] Chippy_boy:
That doesn't make a lot of sense to be honest. UMTS and WCDMA are both 3G protocols. So I am assuming the setting means "if I can't get LTE, i.e. 4G, should I drop down to 3G UMTS or 3G WCDMA". Changing the setting should have no impact on your 4G signal (or speed). Are you on 3G only where you are?

EDIT: and just to add, *#*4636*#* doesn't do anything on my XP1. Strange??!
