How to downgrade T-Mobile LG Velvet 5g - LG Velvet Questions & Answers

Hello, I am hoping someone can help me. I am at my wits end with this phone since the Android 11 update came out. Since I've updated the phone has been insufferable. Chrome freezes when it plays videos and when viewing apps that are web based such as my news feed stories or Google news (which uses some form of chrome or WebView or whatever?) When there's an ad the page goes into what I can only describe as "seizure mode". The page will just flash and not move, videos and pictures will get pixelated, it's made using those apps impossible.
Point is, I want to downgrade my device back to Android 10 and because the T-Mobile version is a snowflake and has a different processor I've had a difficult time finding concrete info on how to do the downgrade or where to get the firmware. Would appreciate any guidance. Thank you

I just happened upon this website: https://lg-firmwares.com/lg-lmg900tm-firmwares/
I'm having problems with the camera and was hoping to downgrade and see that'll fix my problem.

I can't find the correct DLL to get anything working.

You can extract the dll from the kdz file you're trying to flash. I don't know for sure if that'll fix your problem but just a quick bit of info.

Trying to unlock the bootloader, please help ??

Hi Folks.
Just picked up a very nice old EVO Shift and would like to root it.
Certain problems have arisen immediately and I hope someone can direct me in how to solve them, please.
To start with - right this minute all I have is an old XP PC, so the tools for newer OSes will not work for me right now.
I have searched here and in general extensively and found many possible answers - but cannot get anything to succeed yet.
The HTC Dev site allowed me to join, but instead of getting to the bootloader unlocking area it just demands that I log in over and over - so I cannot do it that way.
(I tried maybe 5 different browsers, clearing cookies, cache & all that - same results.)
Kingo has a specific tool for this - but apparently it just uses the HTC Dev site in the background and it fails as well.
The htcsupertoolv3 opens - but it also depends upon that site and also fails.
Many sites recommend downgrading the phone from 2.3.4 to 2.2 - but their files were uploaded aeons ago and I have not been able to find a complete solution anyplace.
The phone connects fine to my PC, I have the drivers & ADB & I've been working at this most of the day today without success.
Right now seems like a good time to give myself and the phone a rest and to resume tomorrow when I get some time...
Any help will be hugely appreciated.
Thanks

Wow.
Is there no hope for this very nice older phone ??
As of now I have managed to find all but the ShiftRR tool and hope someone here still has that & will help me.

Help: Is a New Cubot X6 image available? System is compromised!

Hello!
I would like to ask for help installing either a new Cubot X6 Android or a linux based system. Until recently I wasn't aware of what kind of aggressive trojans for Android happen to compromise a phone to a degree where the solution is to buy a new one. I do not want to accept that. Therefor I am here to ask for help.
WLAN enabled - the phone runs nutts. It causes unknown apps to be installed, ruining the function of the phone completely. I bought it via ebay, a used Cubot X6. I had the device years ago until i sat on it which happened to break the display, but I liked it and bought it again, used. (The used one cost 60 bucks, a replace-display would have cost 35, so I ran with the used one - big mistake as it turned out).
Now, it's root-system is compromised. I set it to only allow apps from trusted sources. I did not download any apps beside well known trust-worthy ones, like google-maps, WhatsApp, all together.
When I first enabled WLAN, it suddenly started to display a message of the shutting down of "org.rain.ball.update" and also "ssCleaner ("suc", "chengele") is trying to obtain your current position", "ymm" cancelled, and several others. If I allow WLAN it automatically downloads 10-20 apps, some of which correlate with my laptop visited websites (alibaba), others apps from sites I have never visited ("sexy videos"). Basically the phone gets so busy that it needs to be restarted to allow any control of the phone.
I tried to fix it with Avaast, Avira, and Malewarebytes without success. With Avaast it also displays: "/storage/sdcard0/.androidsdata/is.jar", but is unable to fix it. I guess I would have to erase the SD-Card too, if I were to have the system replaced, once. None of the above things can be fixed with the tools at hand. The deletions are always interrupted, nothing gets improved permanently.
I immediately did a "Reset to factory condition", but when I enabled WLAN I didn't even install an app - it all started again, as described above.
So, a quick Google-Research turned out, there are trojan-horses, that cover themselves by pretending to be system applications, so that it would be nearly impossible to get rid of the trojan - only solution: buy a new one (See this article wwwDOTblog.lookout.com/blog/2015/11/04/trojanized-adware/).
Now, while I have a broken device and a trojan device, one solution would be to mount the display of the compromised one onto the broken one. I know it's easy to break the display during this. That's why I am here to ask, if someone might have suggestions of what else could be done to have this fixed?
Maybe it would be possible to get an uncompromised mirror-image of a Cubot X6 from the internet that would replace every data on mine? Would it fix it, if I were to install this: "Ubuntu Touch - Version 15.04 Phone"?
Any help would be appreciated. If I were to take a wild guess, I'ld say the trojan horses might have been developed by Apple...... So what am I to do now? Buy a new one?
EDIT: If you were to not believe this to be true, I could shoot a video of it with my laptop. It's really strange, but it is as it is. EDIT 2: Avaast displays a message, the phone has been rooted.
Please help!! Thank you so much!!
You won't get the virus to YOUR phone from replying ...
Am I here at the right forum for this technical problem?
Thanks
Do a search for your rom and instructions on how to flash. It will replace system partition and problem should then be gone.

A google search for "cubot x6 firmware" will give you some good results.
Here's also Cubot forums, with link to downloads.
Hope that will help, and be sure to read up on the subject on how to flash before you start
So many Thanks! You linked me to the perfect spot! Thank you!
While i will redo my laptop with linux soon, you got experience with having linux on the phone? If i wee to try and mes up, it still were possible to go bac to the original cubot files u linked to, correct?
Thank you!!

Lenovo Tab TB-X103F Running Lineage OS 14.1 Amazon Prime Video Force Close

EDIT : One time, Prime Video began to load a few images before it force closed.
First and foremost, I have tried searching to no avail. And the OP in this thread (https://forum.xda-developers.com/general/help/req-walmart-black-friday-tablet-lenovo-t3508508) doesn't seem to know, either. So I'm attempting to cast a wider net here. Thanks in advance.
I have a Lenovo Tab TB-X103F 10.1 inch tablet. It's a budget model that Wal-Mart was selling for real cheap earlier this year. (Only 1GB of RAM.) It originally shipped with Android Marshmallow, but in the months since, TWRP and Lineage OS 14.1 were ported to it. Lineage OS runs great. And even though there's some lag, it's not terrible. Overall a decent tablet.
Anyway, back when I was on the stock ROM, I loved using the tablet to watch Amazon Prime Video. But it doesn't seem to work for me since I installed Lineage OS. I'll install the Amazon Underground app. That works fine. I install the Amazon Prime Video app from there. When I open the app, it'll come up, look like it's trying to load something, and then close. All I get was that Prime Video has stopped. No error code. No way (as far as I know) to output some kind of log. Nothing that I can use to help diagnose this.
Oddly, the OP was able to get it to run on his system without a problem.
I've reinstalled newer builds of the OS with full wipes, even wiping user data. Everything else, including stuff like Youtube works fine, so I know it can still handle streaming video.
I've also uninstalled the app, reinstalled it, cleared the cache, cleared all data. Everything I can think of. I don't know why it refuses to work on my system, but the OP can still use it on his.
Even having Root (with and without Magisk) or no root has zero effect. Still get force closes.
Sorry this ran a bit long, but I hope you can help me figure this out. If you know of some way I can log this to aid in diagnosing the problem, please let me know.
Thanks very much in advance!
EDIT: Here's the logcat pull for this. It's long, and I can't make any sense of this, but I think the amazon prime video stuff is near the bottom. I opened the app multiple times ad let it shut down like it does to make sure I had the whole thing captured.
Hope someone can help. Thanks.
I can't upload the logcat.txt directly, as the uploader says its too big.
Here's a link to a version of it on Google Drive. Hope that will work...
EDIT: See bottom post for logcat file.
New Logcat file
Here's a new logcat file. This one is much shorter, and is directly linked. No google drive required.
I hope you can help with this. I've had no luck, and the OP for the rom can't seem to reproduce the error on his end. Frustrating.
Thank you in advance.

Hey everyone,
I just wanted to help spread the word that there is an official Android 12 ROM for Ulefone Power Armor 13.
This was not publicly announced anywhere as far as I know.
Your phone will NOT receive an automatic update for this (at least as far as my experience goes).
The only way to currently upgrade to the ROM is via the SP Flash Tool.
The only reason I know about this ROM is because I just happened to be looking through their website.
Find it here!

Edit:
I should note - if you do a full wipe & flash this ROM, it WILL flash you a new IMEI number
This IMEI number will be the same IMEI number for everyone running this ROM fully wiped.

I keep getting an "incorrect scatter file format" error when attempting to flash using SP. Either I'm doing something wrong or they messed it up.

What SP Flash Tool version are you using?
I flashed with SP Flash Tool v5.2216
Another tip - move the ROM folder inside the SP Flash Tool folder.

Oh gosh you name it. I went thru numerous versions, some antiquated, some supposedly being the latest versions. Definitely used v5.22, probably twice if not more.
Thanks for the tip about moving the ROM folder. I figured the solution might have to do with the placement of the ROM folder or the SP flash tool folder(possibly both on C: drive) but I just kept on getting the same annoying error message. I'm gonna take your advice right now as a matter of fact. Hopefully it'll work for me as I'm assuming it did for you.
Incidentally, you probably know this already...about the wireless update section having the ability to apply updates 'locally' as well. Tried that a couple of times but no go. Just before you replied I was gonna try the old 'update from recovery mode' but I'd rather try your approach.
Here we go(again!)
Ok.... I'm back. What's it been, over 4 hours since my last post? but in truth I can't claim to have been pulling my hair out for that long. Maybe 2 and a half lol.
>Alternate response: Wow. That was not fun. I somehow managed to boink my phone to seemingly do nothing but start in Fastboot mode.
**But wait, let me give credit and thanks where it's due to benhall. That little tidbit of advice that practically Everyone neglected to divulge about putting the ROM folder in the SP flash folder- a crucial step btw- was the key to getting Android 12 on my PA13. So ben, thank you very much. My deadened eyes sparkled when instead of constantly seeing 'stop feeding me this trash', the little balls of processing hope began-a-spinning to indicate that, yes Virginia, put that dang ROM folder in the SP folder. Again, never saw that in any instructions or any god-awful video that some people made to show how it's done, but instead irritate beyond belief because of their insistence of loud techno music as they talk, or babies yelling in the background while - ok I'm stopping. It was stressful to say the least because I knew I was almost there.
ANd to be fair I actually ended up watching (again) that one video that Ulefone condones on YouTube with the silent Asian (?) guy speeds thru the steps using that client sp thingy with the PDF instructions that Ulefone pushes. I tried SP v5.22 and 6.22 for that matter, but they just weren't working for me. Most likely entirely my fault, but I finally went back to square one with what they suggested and I went over that video again and again and finally....it took!
So, Android 12. It's big, had to reduce the display size because everything is Huge. Visually appealing, nice to get an update.
Funny thing is, sorta like benhall, I happened upon Android 12 in Ulefones Google Drive folder(just bored snooping around). But I was like Whoa we got 12¿?¡! Googled for a quick sec, found this thread cause like the man said it hasn't been mentioned or reported about at all it's so new. If you know you know.
Hey man glad I could help!
Yeah I tried that just out of a hunch & it worked for me haha.
Same thing on my end - no tutorials anywhere mention to do that.

I've had mostly Samsung phones before I recently got the Uley. Sammy's are easier to flash with Odin compared to Mediatek's SP tool, all good tho.
Btw I don't know what camera app you prefer using (stock or 3rd party) but for what it's worth after many tries I've settled on SnapCamera version 8.7.8. The stock cam app is ok, still checking out the new goods with A12, but SnapCamera has a ton of flexibility as far as manual camera controls. Panorama resolution sucks compared to stock panorama res but the ton of other abilities makes up for it.

You can use TTSLex to remove the announcement from Google Phone - Call Recording
(it announces to everyone on the phone call that you're recording them when you start recording..)
FIRST -
In Settings > Security > Google Play Protect > Disable google play protect (this makes installing things google doesnt like work better. I've found it doesnt work as good if you have this enabled before beginning these steps)
Steps I used to remove the announcer
1. Open the Google Phone APK inside Google Play - uninstall/downgrade to the stock version of the app.
2. Open Google Phone - Make a phone call (someone has to actually pick up the phone) - record the phone call (it will be announced that the phone call is being recorded)
3. Download TTSLex
4. Set TTSLex as your phone's text to speech.
5. Open the App Info of Google Phone - force stop
6. I forget if this step is correct or not.. - delete storage/cache for Google Phone apk
(if this doesnt work, try again & skip step #6)
7. Update the Google Phone APK before opening it.
8. Make a phone call & record the phone call - enjoy no more announcer <3
Android Auto - Screen2Auto APK for mirroring your screen onto android auto! (movies/tv shows/youtube on car screen)
Steps -
1. Open Android Auto via Google Play store & confirm its downgraded/uninstalled to the stock APK.
2. Download AAAD
GitHub - shmykelsa/AAAD
Contribute to shmykelsa/AAAD development by creating an account on GitHub.
github.com
3. Using AAAD - install Screen2Auto
(they only give you 1 free install per month, ive tested them all on this ROM - Screen2Auto is the best to use.)
4. Update Android Auto & enjoy! <3
Pro tip for Screen2Auto - if you go to Screen2Auto > Other Settings > Alternative touch enabled > Profile 2 (Poco)
This allows you to use the touch screen of your car to control your phone while mirroring your screen.
(pause/play videos from car screen)
I also disable the Screen2Auto > Settings Launcher > S2A Launcher
But you could play with it & enable that if it suits you better than me.
(gives you a launcher page for launching apps from Screen2Auto - customize which apps are shown on the launcher etc..)
Hey all, thank you for the info on Android 12. I'm kind of out of the game with updating, ROMs, and rooting. I've been running stock 11 rooted since I've gotten this phone. I actually backed everything up and tried to update with Android 12 stock rom yesterday. I haven't messed with spflash since I've had my Armor 7. For some reason I cannot get this to work. I'll tried the Linux sp version, but gave up on that quick and grabbed my wife's win notebook. I downloaded all the drivers, latest adb, tried different cords, made sure it's in the same folder but couldn't get it to go. I know it's something very basic but I can't get past the bar on the bottom of spflash being red and then timing out after a minute or 2.
Would someone be kind enough to post an imbecilic like walkthrough for me? I got that itch to mess with it and mediatek is just a pain in the ass. Well hopefully thank you in advance.
Any idea if there is a non eu rom?

They keep their updates on drive so this might get flagged, but here's the link
Non-EU version - Google Drive
drive.google.com
If you go to ulefone's website, go to support, then software downloads, scroll to the power armor 13. The nonEU folder will be in that under the Android 12 folder.

After first watching a few very annoying walk-thru videos on how to flash a Ulefone I eventually went back to the video link they provided and used the SP flash version they advised, and it worked(go figure right?). Granted there's no audio and the guy briskly goes thru it, you just gotta slow that sucker down, hit pause and rewind to fully and correctly grasp what's happening. And as was mentioned above, and I think you got this part, the importance of putting the rom folder in the SP flash folder.
Also make sure you're either using the stock charging/data cable or something very close to it(ie. no cheap stuff). Here's the video Ulefone says to follow and the one that eventually got me to successfully flash Android 12:

Backup Mirrorless Camera SONY ILCE-6500

Hey ya'll!
Been running snooping around the xda forums for a while now (2017?), and even compiled lineageos for myself last year for the first time! Gots a question not phone related though. (o:
I have acquired a sony alpha 6500, and it still has the original firmware on it that it shipped with when it was new (2016). I'd sure like to save that before updating to the newest one, as it seems it could have some value for developers as well as for historical/museum value for archive.org. It seems like it's android based as some of the documentation I was reading suggests that opening an android shell might be useful to me, which I've never done/don't know what to do with.
Some folks have had some success with this tool: https://github.com/ma1co/fwtool.py . I did run the tool with the "--help" command, but it didn't offer any insight to the switches that are available or how to use them and I can't seem to find a manual for the fwtool. I think this is the tool I'm supposed to use to get the camera to give up everything that's on it right now, but i don't actually know.
This site won't let me make an account right now to ask for help: https://www.personal-view.com/talks/discussion/12756/sony-alpha-hacks-talk/p11 which seems to be the developer of the software that fwtool.py is a fork of possibly? It didn't have any information about how to use the flags/switches for the app either. That's why I'm asking here
Is anyone able to explain from this information I've found so far what command I would need to run (from linux terminal or windows cmd/powershell) or if there are additional steps needed in order to save or backup the current "ROM/OEM Firmware" that's currently on the camera? Or point me in the right direction?
Thanks!
