[Q] random crashing/system incidents - Sony Xperia M4 Aqua

Hello,
I've got a weird problem with my M4
I've got the phone for over 2 years, it's the E2303 version. It worked perfectly normal until at some point it started randomly crashing (Note: the phone wasn't rooted at this point and it had Android 5.0 26.1.A.3.111 (carrier version)). The crash looks like this: the phone freezes for like 2-3 seconds not responding to any input, then the screen goes black, then it boots up normally. However it isn't rare for it to crash like that, then while booting up crash again in the same way, repeat a couple of times. In System incidents it's counted as just 1 incident. I also noticed that sometimes after successfully booting up after crash wi-fi, mobile transfer or airplane mode are switched on/off, not as before the crash.
I thought the problem would go away so I waited a bit, but it kept on crashing. Sometimes it can go for a few days without crashing, sometimes it crashes a few minutes after last crash.
I've tried fixing the phone using PC Companion (it also updated it to 6.0) - didn't help. I've tried flashing a stock 5.0 ROM using Flashtool (same as before: 26.1.A.3.111, but a non-carrier version) - also didn't help. Also I've got the phone rooted by now. I don't know about bootloader, the service menu tells me Bootloader unlock allowed: No, even though I've got the OEM unlocking switched on in the Developer options (I'm not that tech savvy in case of phones and I'm getting lost a little bit).
I've got some screenshots here:

I hope there is a way to fix this phone, this crashing is starting to get a little annoying...
Any help would be really appreciated

[Q] Help needed for unlocked STOCK T-Mobile HTC Amaze

Hey everyone, I've searched thru the forum looking to see if someone had the same issues I did, and the stellar assistance that was given to others with various problems, I'm hoping that I can get the same (haven't seen anyone with my particular issues yet).
As mentioned in the title, I'm using a stock T-Mobile Amaze, unlocked and I'm using it in Barbados. A few weeks ago, a notification popped up on my phone.

Naturally, I was curious to see what this update was, but after ensuring that everything that was required for the update was in place, I see this...
...which I'm sure means there's some error in installing the update. The phone freezes, and I can't get out of this without doing a battery pull a la blackberry. This is issue 1.
Issue 2 is that a lot of my menus have wrong names, e.g. the 1 for Wireless connections says "Turn It On"
and even the options within the menus are wrong, e.g. In the display menu, to set the screen brightness, that option is entitled "Set A PIN code to lock your UIM Card"
Further to these, often when I try to access many of my settings, the whole shebang crashes, and asks me about sending an error report. Til now, nothing has changed in that regard. Any assistance to these problems would be GREATLY appreciated. Thanks in advance.
Your best bet is just to do a master reset on the phone. It should clear up all those issues.
tried it...didn't work (well, the menus still are screwed up, and the settings keep crashing when i try to access some of them, like the Sound menu.)

Have you tried locking your bootloader and flashing the stock firmware?
You already unlocked your bootloader, right?
Just flash a custom rom.
If you REALLY want to flash the 1.43 update then relock your bootloader and flash this: http://goo.gl/KvHzj
Rename it to PH85IMG.zip and store it on the root of your sdcard.
It will update everything.
Then unlock your bootloader again, reroot and you'll be good.

[Q] My failed rooting attempt, need your help

First thing, I am very very sorry if I posted this in the wrong topic, but I am in an extreme rush.

I don't have a wireless router so I wanted to connect my phone to my PC through USB cable and share my internet to download some things. I found this tutorial which I decided to follow. In it, it said I needed to root my phone. I decided to do it and followed multiple tutorials but later on I found out they weren't working for ICS. I did download Java JDK and Android SDK along with files I needed and the google USB driver.
I found this tutorial from here though and thought it would work since this is quite an awesome community. I downloaded the files and ran the .bat file. Everything was going well and then and my phone restarted (as it should), but once it started again it was very slow (which could be caused by some backup that bat file created and my low phone memory with no SD card in it). That's all fine, but after like 1minute my screen goes black. I push the power button (used to lock/unlock phone) and only those 3 buttons glow on the push and turn off when I push again. All I can do is to pull out the battery and start the phone again. I restarted it a few times and once it acted normal, but when I accessed my galery it was messed up and when I tried xperia galery it was even worse (didn't show 3d well and there was lots of flickering and similar...). After that I restarted it to see if that would fix the messed up gallery and once phone booted screen went black again.
I tried the unroot option in the bat file and it gave me this:
This is my first android phone and I got it like couple of weeks ago so please have mercy on me ...
Sorry, I fixed it after couple of hours of work...had to restart my whole phone in the end.

Poco X3 NFC android 10 rollback

Let me start by saying I am not rooted no twrp just plain stock , with locked bootloader. Also EU version.(V12.0.8.0.QJGEUXM)
A few months ago I downloaded the Android 11 Rom V12.0.6.0.RJGEUXM through the phone even though I am not on any trial program.
It installed easily on my phone , some people have had to use other methods...so I read.
Anyhow , I thought it was way too buggy and needed to downgrade.( Even after the the 2 other upgrades to V12.0.7.0.RJGEUXM. This is what I did to rollback if someone else is in the same boat.
I had to wait 3 days to unlock my bootloader,
Then I used the MiTool to select the ROM I wanted.
The problem then is the bootloader is still unlocked after you flash the new ROM, you need to use ADB command " OEM lock" to relock then phone , it should erase everything then go back stock. I am still learning with this Xiaomi device so I had to learn this from different sources and hope it helps somebody else out.
Soz if this is common knowledge or wrong part of forum!
thanks for the info but why did you downgrade did android 11 lags the phone or what

1) WiFi issues and random reboots, when the phone booted (on its own accord) on reboot the wi fi took quite a few minutes ( over 5 minutes sometimes longer) to get back online.
2) The speaker volume seemed too quiet for video and calls.(on at full volume most of the time).
3) Not so polished, sometimes would be a bit laggy other times not.
At the minute Android 11 for the Poco is still Beta, I am sure these problems will get resolved. The moral of story ... Wait for OTA instead of forcing updates.
i used xiaomi flash tool to flash fastboot rom and selected this to keep unlocked bootloader

Help: Phone randomly restarts & sometimes stucks in boot loop!

Hey there,
as mentioned in the title my long used Honor 9 started to randomly restart (sometimes multiple times). I can be triggered when opening/closing different apps, browsing through youtube or listening to spotify. Sometimes the phone even restarts after I entered my sim-pin, so I can't use it at all at the moment which is very frustrating. Most of the time, if the phone restarts, it ends up in the eRevovery Mode or the Emergency Backup Mode. There I only have the option to shutdown/restart/backup/reset the phone. I always press restart and with a bit of luck it starts completly normal so I can use it... until it restarts again on its own at some point...
I never had issues with this phone until last week. The last few days those random restarts and boot loops ending in the eRevovery Mode happened very frequently.
Here is some info:
I use this phone since November 2017 with an external 128GB SD-Card
4GB Ram, 64GB internal memory
SD-Card used 100GB/128GB, Internal used 30GB/64GB (so technically there is enough space left)
EMUI 9.1.0.231 (strangely it shows the same version as an "update" sometimes, see picure down below)
In 2019/20 I changed the battery once (old battery was bloated/swallen, no problems occured after the replacement)
My phone is not rooted
... if someone need more informations about my phone: just ask!
What I have already tried to fix the problem:
Downloading "the same version update as already installed" (see picture down below)
Deleting unused apps
SD-Card removed
Cleared System Cache
Using "safe mode"
Doing a factory reset
Unfortenately nothing helped.. Someone has an idea whats the problem and how I can fix it?
Thanks in advance!

UPDATE:
I think I found the issue. I just saw the reviews of the battery I changed in late 2019 (see: here). Nearly every review is stating that this battery is causing the restart problems. This is a little bit strange because I used this battery for like 2 1/2 years and had no problems until early 2022 when I suddenly experienced the same issues.
Has a new battery solved the issue?
I'm currently having the same issue.

Viewport broken after flashing TWRP

Hi, first time playing vith custom ROMs
I've SIM unlocked and unlocked bootloader of my old XPERIA XZ1.
I followed this tutorial https://www.getdroidtips.com/lineage-os-18-1-sony-xperia-xz1-compact/ in order to install Lineage OS 18.1 using TWRP
So I've downloaded all the software, images, drivers and such... then used adb and fastboot to flash TWRP.
When I finally managed to boot with TWRP my screen looked like this
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
The display appears to be somewhat broken or misconfigured, with a smaller version of the display on the top left corner of the screen and everything else is RGB snow.
Touchscreen is responding on the non broken part of the screen only. It looks like this as soon as the screen turns on, even before Xperia booting sequence.
I couldn't manage to install Lineage properly either. I got stuck in a weird boot loop. Taking up to minutes to boot with the lineage loading animation and a black screen. I was able to interact with the parameter tab but could open any app or do anything else.
Then I decided to restart from scratch and reinstalled a stock ROM with Sony Xperia Flash Tool, following this tutorial https://www.getdroidtips.com/sony-xperia-xz1-stock-firmware/
Now I have a working Android system running on the phone but it didn't fix the screen.
It doesn't detect my SIM card either.
This isn't my main phone so it doesn't really matter to me if SIM doesn't work, but i'd like to fix the screen.
It might have something to do with the fact that I've tried to flash a Lineage ROM made for Sony Xperia XZ1 Compact. Mine is not a compact, but there was no official ROM for my specific model. This was the closest match and I thought this should be OK. I was SO wrong, lol
I couldn't find another thread with the same screen glitch, but I highly doubt it to be unique. I'm probably just using the wrong keywords.
Any hint would be greatly appreciated
Thanks !
