[Xiaomi Mi 9 Questions & Answers] SlugUnchained:
First of all, i fu**ed up.

So, I was on MIUI.EU 9.8.22 running Android Q.

I tried to install Syberia Rom.

Full Wipe, flashed image vendor, rom, gapps and then magisk.

Rebooted to system. Didn't work, so I went to recovery mode to fix it. It was everything encrypted so I couldn't find a way to go back to miui.eu or install another rom.

I tried to install a twrp that supports encryption via fastboot.

Now I can't go anywhere but fastboot. Any ideas?

Forgot to say, BL is Unlocked

Thanks in advance

[OnePlus 7 Pro Questions & Answers] Tdeljr:
I am interested in getting either this phone or the regular one plus 7, but I have horrible time using a oled screen due to pwm. I suffer from severe headaches and eye strain.

So Im wondering if there is anyone else out there that suffers like I do, is using this phone and does dc dimming actually help?

Please if you dont know what pwm is or if it's not a problem for you Dont Comment.

I appreciate any help you can give.

Thank you!

I wonder if the 90Hz refresh would help....
[OnePlus 7 Pro Questions & Answers] equlizer:
I don't have that issue while using dc dimming but if i turn it off, after about 5 min i do notice my eyes hurting and stuff. DC dimming only works when the brightness is very low (i believe)
[OnePlus 7 Pro Questions & Answers] daninantro:
Hi, I know the thread is old but I wanted to share my views about this topic.

I am one of the few people who are sensitive to PWM flicker used in OLEDs. Before I switched to OP7 Pro, I had OP3. OP3 display destroyed my eyes and i came to know that PWM was the cause of my eye discomfort and headaches.

I switched to OP7 Pro as it had DC dimming which reduces the discomfort to PWM sensitive users. And to a huge extent this has helped me with the discomfort. But I still get headaches after prolonged viewing of the screen so I take frequent breaks and avoid extensive reading on the phone.

I have done some research about OP7 Pro display and turns out that PWM frequency is around 350hz (the more the better) when the screen is kept at 90Hz refresh rate and around 150hz PWM frequency at 60 Hz refresh rate. SO it is advised to keep display at 90Hz. All other phones have roughly 250Hz PWM frequency. Also, our phone’s display uses PWM when brightness drops below 50% which is really good as some other OEMS use PWM brightness control below 95% display brightness. So I keep the DC dimming on and use the phone at low brightness. I also use an app called OLED saver though I dont know whether it is redundant as it does same thing as DC dimming.

Recently I started noticing something after upgrading to OOS Android 10. I noticed that DC dimming implementation is different on OOS android 10 than on OOS android 9. I started getting headaches and eye discomfort on OOS android 10. I noticed that the PWM flicker is much more evident on OOS 10 .I used camera pro mode on another phone and reduced the shutter speed to 1/1000th and viewed OP7P screen through it. The flicker was evident. So I reverted back to OOS 9 and the discomfort was greatly reduced. I think I will stay on OOS 9 for the future :p

There is one thing I am very clear about is that all the OLED screen phones nowadays use PWM brightness control and even if DC Dimming is implemented the OLED screen will still flicker slightly. And if anyone is very sensitive to PWM then buy LCD screen phones. It’s the only option
[OnePlus 7 Pro Questions & Answers] MarcoRefaat:
Same Problem

Actually I am facing the same problem I can't look at the phone more than 10 minutes

and installed "OLED saver" and nothing happened the same problem

I was wondering is this a problem my eyes with all AMOLED displays or it's just Oneplus only ?
[Moto X4 Questions & Answers] crazyramen:
Is this thread more appropriate on discussion? If so I will delete and repost there.

I had a hell of a time trying to root my brand new X4. At first I was trying to use my recently built (Ryzen 5 1600, Fatal1ty AB350 Gaming-ITX/ac) desktop. Fastboot wasn't working and giving me this or similar errors

(bootloader) is-logical:recove: not found
Sending 'recovery' (33304 KB) FAILED (remote: 'unknown command')
fastboot: error: Command failed

and on the X4's bootloader logs screen it looked like the commands were also getting cut off and scrambled. It would say things like

cmd: getvar:has-slot:recovery
cmd:
cmd: getvar:is-logical:recove

or

cmd: getvar:has-slot:recovery
cmd: max-downlo
cmd: getvar:is-logical:recove

I thought this might've been a driver issue so I reinstalled Motorola Device Manager and the drivers and restarted a few different times. Finally I stumbled upon another thread that suggested using USB 2.0 ports. SO when I tried it with my USB 2.0 ports on my desktop it was still giving me the errors. So digging into device manager I found that even the USB 2.0 ports were part of the "AMD USB 3.1 eXtensible Controller" . So when that didn't work I finally tried on my old 2012 Laptop and bam slam kaboom it worked perfectly.

I've got a spare USB 2.0 header on my mobo so maybe I'll pull a connector off of my old desktop and try that out. I'd be surprised if it didn't run on the USB 3.1 Controller since it's an ITX mobo and maybe can have fewer controllers running?

Has anyone found a software fix for this on modern computers?
[Moto X4 Questions & Answers] guhvanoh:
Fastboot/adb doesn't work on ryzen. You're better off getting a USB 2.0 hub to do this stuff. USB 3 has problems. However, you can use USB 3 to transfer data. Go figure that one out...
[Moto X4 Questions & Answers] NeoandGeo:
Also note that USB-C will generally cause weird issues up to and including complete failure to work properly at all if using USB-C to USB-C connections. For Fastboot always use USB-C to USB-A cabling and USB 2.0 ports are highly preferred.
[Moto X4 Questions & Answers] crazyramen:
Hmm ADB works fine when booted to OS and in Recovery when attached to USB 3.0. I suspect that even using a USB 2 hub would cause the same issues, since it'd be using the USB 3.1 Extensible Host, right?
[Moto X4 Questions & Answers] crazyramen:
I didn't know that, but I have been using the C to A cables, and also trying the 2.0 port on my desktop. Like I said, it's all routed through the USB 3.1 eXtensible Controller, though. I'm a little annoyed that the USB 2.0 port is routed the same way, although I'm not sure if that's the way it's always done/if that's what causes the issue.
[Moto X4 Questions & Answers] NeoandGeo:
There is no telling. I am able to use a USB-C to USB-A cable through my USB 3.0 ports on the front and back, but use the USB 2.0 ports just as an extra precaution. Speaking of the USB 3.1 eXtensible controller, on my Maximus X Hero board, I have to use generic drivers from Microsoft in order for anything to work right. Installing the latest ASMedia USB 3.0/3.1 drivers send my OS into a tailspin that eventually forces a reinstall of Windows due to OS corruption. What once was the most reliable piece of a PC is now a convoluted mess. :p
[OnePlus 7 Pro Questions & Answers] NotATreoFan:
I'm currently running OOS 9.5.13 with arter97's kernel. I converted the data partition to f2fs and it have been very stable for me. Can anyone tell me if the stock OOS kernel still supports f2fs? I suspect it does since I was temporarily running the stock kernel after the 9.5.13 OTA, and didn't get any errors from apps trying to access data on the phone.

Not interested in formatting my data partition, and if it does not support it, I will just wait for an updated kernel before going to 10.
[OnePlus 7 Pro Questions & Answers] keaheng:
It's working fine. I'm on f2fs Android 10 stock kernel. Waiting for arter kernel as well.
[OnePlus 7 Pro Questions & Answers] NotATreoFan:
Thanks! That's what I was hoping for.
[OnePlus 7 Pro Questions & Answers] JhinCuatro:
How????? IS there any guide to convert to f2fs? I tried and tried and it never works no matter what guide I've used.

I have TWRP, convert data partition to f2fs, all from a fresh wipe. I installed oos and it never boots; always into recovery. FOR YEARS. EVEN ON MY OP5T. The guide is clearly not working for me and never has.
[OnePlus 7 Pro Questions & Answers] NotATreoFan:
Did you install OOS after converting to f2fs? You cannot convert without a clean install after.
[OnePlus 7 Pro Questions & Answers] JhinCuatro:
Tried that (via twrp i guess?). Only reboots to recovery. Already wasted hours, and I assumed the guide was supposed to pretty much actually say what to do, which it clearly doesn't if another oos installation was needed after (which i already did anyway..)

Guess f2fs will only be worth considering in the next few years; not worth all the problems just for a marginal increase in performance on an alreasy fast phone.
[OnePlus 7 Pro Questions & Answers] NotATreoFan:
Format Data, reboot to TWRP, convert to f2fs, install OOS OTA, reboot. If you wind up in stock recovery, do a factory reset from there, and then it will boot.
[Google Pixel 3a Questions & Answers] Helios747:
Hi,

With my playing around with AOSP on the 3a, I've found TWRP to be reasonably reliable to restoring me to a functional phone after I blew something up. What I haven't tested is rolling back from Android 10 builds to a Android 9 backup via TWRP.

I'm wanting to try out Android 10 AOSP builds using the RattlesnakeOS AWS Stack scripts but I don't actually know if my Pie backups taken with TWRP will restore correctly. Especially since the partition layout is changed with Android 10.

My intuition tells me I can do this to roll back to an Android 9 TWRP backup.

1. Flash an Android 9 factory image from Google via fastboot. This will allow a downgrade as it will repartition the phone back to the Pie partitioning layout

2. Boot TWRP and restore my Android 9 backup. System, Data.

3. reboot.

Does this sound reasonable? Basically I have a free weekend and I'm very bored and feel like blowing up my phone all day
[Google Pixel 3a Questions & Answers] wewep:
Hey guys,

I saw a deal where I could get the Pixel 3a for 300€.

And taht sound crazy good in my opinion.

But first I have some questions: The Roms/Kernels section here is pretty small. Isn't there much developing for the Pixel 3a?

How's the battery? Especially the standby drain.

Would you guys buy the pixel 3a again?

I'm currently using a Samsung Galaxy S7 with a broken camera.

First I wanted to wait till the Pixel 4 release, but 300€ sounds amazing...
[Google Pixel 3a Questions & Answers] bblzd:
It's a great phone with long battery life. Development seems to slow but there might be more over on the XL side of the forums. I'm guessing those would be compatible seeing as the devices are mostly identical on the inside.
[Google Pixel 3a Questions & Answers] vinz244:
Got mine a few weeks for 350€ so 300€ is a great deal.

> How's the battery? Especially the standby drain.

For me it can easily last two days if I'm not using it too much

> The Roms/Kernels section here is pretty small. Isn't there much developing for the Pixel 3a?

Since it's up-to-date stock, most people dont seem to want / use custom ROMs. But you can find a few tho. Keep in mind some dev may not be shown on XDA like grapheneos which is developped for all pixels officially

> Would you guys buy the pixel 3a again?

You mean if it broke? I'm not sure, if I had the money, probably, but I also bought this one because it's one of the last <6" phones.

With Pixel 4 coming? I can't really tell since that part depends more on your budget, and your needs.
[Google Pixel 3a Questions & Answers] yabadabadooo:
It depends what your needs are.

What stand by time is good for you?

2 days and ~4h SOT works fine.

Yes development is very poor and nearly doesnt exist.

But hey it's stock AOSP no Samsung bloatware

Camera is great also

I would by it again, i would also buy it for 400€ again.

But lets wait for the Pixel 4, maybe 4a?
[Google Pixel 3a Questions & Answers] Archangel:
I think it is an amazing device. I bought mine when it had the 100 credit used in the Google Store and I can say it is one of the best devices I have had. I had the Pixel 3 when it first came out and other than a few obvious differences I do not really miss it at all since purchasing the Pixel 3a. Battery life is on par with other more expensive phones. Love the features and the display. About the only thing I wish it had was the Pixel Experience when you place it on the Pixel Charger. Other than that 300 is a steal.
[Google Pixel 3a Questions & Answers] moo113:
I'm a big fan and would highly recommend. It's the first device in a decade I haven't rooted with 2.5 years of confirmed system updates remaining.

I do miss having wireless charging and a notification LED, but these are acceptable compromises.
[Google Pixel 3a Questions & Answers] sic0048:
I have a 3a XL and will be buying another Pixel soon (for my wife). I'm trying to wait until the 4 comes out to see what kind of deals they have on the 3 or 3a. I would absolutely buy another 3a, but I'd also pick the 3 over the 3a at comparable prices. The 3 is almost as cheap as the 3a, and I'm hoping it comes down in price even more with the 4 release coming up in the next few weeks.

The OTA Settings manager established the T-Mobile MMS and GPRS data accounts and they do match what T-Mobile's settings on their website. Anyone know what needs to be corrected?

Hi i was wondering if someone could tell me whats a good file recovery for a micro sd card on android i was looking into recovering my MineCraft worlds that was saved that got deleted on my ext micro SD card thanks
[Xiaomi Mi A2 Lite Questions & Answers] Grzojda:
Hi!

So i formated my sd card as internal memory, and few days later just remove it from slot and format when in other phone. Then i placed it back in my phone.

The problem is, now in file explorer it seems i have 0B/1B memory free, I can't make screenshots, make photos or download files, but i can download apps from google play.

Any ideas how to fix it? I didn't try factory reset yet, but it is last option for because phone is rooted, and i have apps that aren't backed up at google.

magisk rooted

no twrp

android 9 PKQ1.180917.001.V10.0.10.0.PDLMIXM
[Xiaomi Mi A2 Lite Questions & Answers] nikoman1987:
As far as I can tell , when you formatted as internal storage , you have transferred the data from the main storage to SD card. Before you remove any SD card , transfer the data from the card to internal storage , then format the SD card as external from the phone. You didn't do that , so you messed up the partitions right now. For me the Factory reset is not the last , but the only option. Never take out the SD card if it's not formatted as external.

The last thing that you can try before factory reset is to try to flash the stock firmware via MiFlash tool, but you need to choose the option "save user data " from the bottom right corner of the tool, the hit the flash button. It might work. If you don't wanna use MiFlash, just decompress the stock firmware and execute this . bat file : flash_all_except_storag.bat

You can try to boot in TWRP and backup the data partition. But I'm not sure that will help, but these are the options that I can think of.

[Moto G7 Power Questions & Answers] :
So after I installed the Official Android 10 GSI just out of curiousity, it worked and the only reason I didn't stay with it was because it didnt have the new gestures and no lockscreen options. Everything else worked amazingly.

At this point I just wanted to install LineageOS and root but the phone kept rebooting to TWRP over and over no matter what I'd flash and no matter how many times I wiped it kept rebooting until it eventually got no response at all.

I tried everything restoring back up nothing, when I tried just flashing the zip file the recovery screen just kept flashing then rebooted back. I cannot save this for life of me I am left with a paperweight.

Ive tried the classic Moto G force restart trick but no luck in anything. No matter what I tried now it wont respond to any button presses. Am I just screwed? I'm waiting 24 hours before trying again while plugged in. What am i to do?

Easiest way (that I have found), is to simply use a Backup tool like SPB Backup. I keep a backup of each ROM I might go back to (and keep the downloaded ROM as well). Of course I name the backup file appropriately so that I know which ROM it is from (e.g. Backup060108_Sleuth3.exe). That way if I need to restore, I can simply Flash back to that ROM, and then run my restore. This has worked in almost every case.

I have no clue what happened, but every time I try to load the camera, the system freezes. The camera can't be opened anywhere.

I've used TWRP, etc, for a long time, no problems. I decided to try the LOS17 ROM, and now I can't get the camera to load no matter what I do. I've even reset the phone using LGUP and installing the KDZs, to no avail.
