i used sp flash and wwr. you can prob pull the boot.img pretty easily, but if you tried to take an OTA and it got corrupted, that might not work anyway. the vbmeta an empty one. this boot.img is from the most up to date ota which i got yesterday. i ordered a refurb version of this tablet and started messing with it yesterday. i have a copy of the full ROM dump as well. let me know if you need pieces and I can get them to you. you might be able to flash a few of the partitions and get it running again. can you get into fastboot?
[Walmart Onn Tablets General] Mayday_Channel:
which sp flash version? im on the latest 5.2152, every time i try to dump the full rom, it hangs on 0% readback. same with trying the boot.img. what was the full rom length, just to confirm? i got 0x750000000 from wwr
[Walmart Onn Tablets General] goldensun1893:
I used 5.1524. i had this issue as well and had to update the com port drivers. i used Iobit driver booster for this and it found the right driver. and yes thats the correct length for the one i dumped. i have the full thing on mega if you just want to flash it with sp flash tool.
[Walmart Onn Tablets General] Mayday_Channel:
that would be very nice. please post. thank you

i got rid of userdata and cache to shrink it some.
[Walmart Onn Tablets General] goldensun1893:
let me know how it works
[Walmart Onn Tablets General] Mayday_Channel:
could i please get the cache & userdata partitions? id like to keep a complete rom for archive. it seems to have flashed ok, but it broke wifi and its still stuck on january 5 patch. oh well, thats why i have 2 of these
[Walmart Onn Tablets General] goldensun1893:
ill drop them on there. be warned the userdata.img is something like 28GB. If you have the NV RAM Warning: ERR 0x10, there are a few tuts on here to fix that. Its common with SP Flash and MTK chips.
[Walmart Onn Tablets General] Mayday_Channel:
I think I figured out why it doesn't work. Spft isn't flashing super.img. even if I edit the scatter file to add super.img. I'll do some more trouble shooting at lunch
[Walmart Onn Tablets General] Mayday_Channel:
alright lets goooo. fixed it. just needed to change a few things in the scatter file and change the vbmeta files to img. next ill start experimenting on patching lk.bin to remove the ORANGE STATE text. thanks for the rom dump
[Walmart Onn Tablets General] beachmiles:
NICE! I took a leap of faith and did this on my Oct 5th 2021 Security update build and it appears to have worked and Im rooted with magisk!!! I added a few additional steps to your commands just in case

fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img

fastboot erase cache

fastboot flash boot magisk_patched-24100_w97F6.img

fastboot reboot

I found a USB ADB fastboot driver that was signed and worked on my windows 10 x64 system but I had to go through the "Have Disk" manual driver install and installed even though it wasnt supposedly designed for my hardware. So insane the hoops to do this...

MT65XX-USB-VCOM-drivers\MT65XX USB VCOM drivers\Google_USB_Driver_rev4

Had trouble updating to Magisk to 24.3 however, not sure what pitfall I hit.

Wondering if I should be happy with root or try and flash TWRP and try a different ROM.
[Walmart Onn Tablets General] Omaraguilar1933:
Iam in need of some help i am not sure if i have to install something to the tablet or pc but when i do the command "fastboot flashing devices" on my tablet just says on the bottom left =>FASTBOOT mode... and it doesnt change and on my pc it says <waiting for device> idk what am doing wrong can someone help me
[Walmart Onn Tablets General] MidnightSakura:
Followed the same steps and managed to get it working on my tablet that was on the same secpatch. However I also ran into an issue updating magisk. It acts like it worked fine and then when it reboots it asks to patch again.
[Walmart Onn Tablets General] MidnightSakura:
Had to patch boot file manually and flash via fastboot. Still get an annoying popup when opening magisk but it's now updated to the latest 25.0.

To update run the following:

Root using ops method

Start your device and make sure that everything is rooted and working

adb reboot bootloader

fastboot flash boot [PATH TO MAGISK PATCHED 25000]

fastboot reboot

Tested on Oct521 SecPatch on a devices already rooted with OPs method. Do this at your own risk. Make backups, etc etc.​

[Walmart Onn Tablets General] Vorton:
I just wanted to say thank you so much for this!!! I know I am a little late to the party but I have been looking for a method to root this for a while, Unfortunatly I am still stuck with the walmart button but I am working on a way to remove that now. Again thank you so much!
[Walmart Onn Tablets General] Da Hangry Ninja:
Ive been trying to reoot mine for about a week now and adb work ect but it wont fastboot even with driver installed but never sees the tablet ive tried multiple usbs a laptop and a desktop with no luck
[Walmart Onn Tablets General] Renate:
Can you see your device in fastboot mode in the Device Manager?

Does it have a driver? Did you use the Google driver?

What is the USB VID/PID? You can see that in Details > Instance path.

Which Windows are you using?

You can patch an .inf file to add the non-standard fastboot VID/PID.

Copy android_winusb.inf to your own .inf

Using the examples in there add your VID/PID to two places (86 & AMD).

Install the driver as unsigned (advanced reboot, etc).
[Walmart Onn Tablets General] LosSantosJeep:
Hi everyone. Looking for a little help here. I am stuck betweeen step 2 and 3 and am obviously missing something. I have installed the google driver as well. After the reboot bootloader step it goes directly to a fastboot prompt in the bottom left of the screen. I cannot get to any options or get the device connected via adb after that. If i click on the fastboot.exe it does not open a program. Am I missing a step or doing something wrong? Thanks in advance.

2. ADB:

adb devices (to make sure you are connected)

adb reboot bootloader

~boots to bootloader~

[[ STUCK AT THE TABLET PROMPT HERE]] - Have to hard reset to get back into tablet.

3. FASTBOOT

fastboot devices (to make sure you are connected)

(WARNING: the next command will factory reset the tablet)

fastboot flashing unlock

(follow volume key prompt to unlock and then device will reboot and bootloader is unlocked.)

You will see "orange state" as it boots if it worked properly. I don't have any interest in removing this message so you'll have to go elsewhere if you do.
[Walmart Onn Tablets General] pearce29:
Having same problem you ever figure this out?
[Walmart Onn Tablets General] b1zk1t.1337:
i actually found a way to root the gen 3 10.1" if anyone is interested. it involved a mediatek exploit

to obtain the boot.img / vbmeta.img
[Walmart Onn Tablets General] maverickbleh:
bluetooth and wifi refuse to turn on after flashing boot.img and vbmeta.img, does anyone know how to fix this?
[Walmart Onn Tablets General] Renate:
Probably a mismatch because the Magisk'ed boot that you put in was not based on your original boot image?

They've starting putting everything in kernel modules (WiFi, BT) and the versions must match exactly with the kernel.
[Walmart Onn Tablets General] maverickbleh:
having root access, is there a way to correct it?
[Walmart Onn Tablets General] Renate:
I meant to say:

Did you Magisk the boot image yourself or did you get the already Magisk'ed boot image from somewhere else?

I see someone posted a Magisk'ed boot image above, but time has gone by and that is probably out of date for your kernel modules.

Is there an (current) update.zip that you can get your hands on?

Or is there an even newer update that you can update to (by Update in Settings)?

If you install a whole new update, then fastboot boot oldmagisk.img you'll have root but broken WiFi.

You can use your root to pull the new stock boot image, Magisk it, then flash it.
[Walmart Onn Tablets General] maverickbleh:
i took the boot.img from this page, and i magisked it myself, so i guess the boot.img was not fully compatible. And since the wifi does not work, I can't do OTA updates. So I guess I screwed myself lol. At least it's not my primary tablet, so it's not too sad.
[Walmart Onn Tablets General] Renate:
Well, if somebody has either a stock or a Magisk'ed boot image that matches your system you could get going again.

Try these updates or boot images: https://androidfilehost.com/?w=files&flid=301680

Keep track of any boot image you have that halfway works.

See first if fastboot boot whatever.img works before you flash.
[Xiaomi Poco F1 Questions & Answers] devil1:
Hello all,

It's a long time that's i haven't post a thread here but i have a question.I have a Poco with MIUI Global 9.6 Stable (9.6.25.0) for ROM with a Android Version 8.1.0 OPM 171019.011 with root acces, unlocking bootloader and TWRP 3.3.0-0 installed.

I would upgrade my phone to something "newer" (A ROM with Android 12 if possible) and conserv the root access and my apps.

I have read that now ,we should have 3 files to do that (firmware,system and vendor) to make a wipe and install new ROM with TWRP.

So my question:

-Is it possible to upgrade Android 8.1.0 to Android 12 witn a new ROM? (i have read something about kernel in Android12 but haven't understand all)

-Have i missed some steps or just download files,boot TWRP,wipe and install newer ROM+firmware and vendor appropriate is good?

-Which ROM do you recommend?

Thanks for the previous answers.
[Xiaomi Poco F1 Questions & Answers] Retrial:
It's not possible to switch from stock ROM to custom without doing clean install. You will have to root again.

First update to latest Official Stock ROM, then take backup of your files to your PC or to SDCard (if you have one) , flash to latest Official TWRP and check my POCO F1 Ultimate Collection & Guides. You can find everything there. I have awarded recommended ROMs in my collection.

Feel free to ask if you have any question regarding the guides.
[Xiaomi Poco F1 Questions & Answers] devil1:
Thanks for the answer.I have begin to read your guides.

If i understand good,it's not possible to conserv my root,unlock bootloader and twrp when i upgrade to android 12? Automaticaly i should root again my phone and restore with titanium backup my files,contact,....?
[Xiaomi Poco F1 Questions & Answers] Retrial:
First you need to take backup of your files to PC or External SDCard.

Then you should update to latest version of MIUI via OTA if it's possible or via TWRP (you can use the stock recovery rom to do it via twrp). (You can also use my guides for clean install stock rom)

Then you should unlock your bootloader if it's not already unlocked.

Then flash latest Official TWRP.

Then flash latest firmware (not vendor) just to make sure you are on the latest. (You should be on latest firmware after updating to the latest MIUI version)

Then Wipe everything + format data according to my guides and flash the ROM you want. If you choose A12 Pixel Experience or crDroid keep in mind that these ROMs use their own recovery because these are encrypted by default ROMs and TWRP can't handle the decryption of A12 encrypted ROMs

yet

. So to make OTA updates and that stuff work correctly devs of these ROMs decide to use their own recovery which can handle the decryption of encrypted roms and as result to make OTA update work fine. Check the installation instructions of these roms in their threads. (Afterwards you can use adb sideload to flash stuff using these recoveries)

After that, flash Magisk since you want root.

Then you can restore titanium backup if you want.
[Xiaomi Poco F1 Questions & Answers] devil1:
OK i follow your instruction.Thanks
[Xiaomi Poco F1 Questions & Answers] devil1:
Hello retrial,

I have now updating my phone to MIUI Global 12.0.3 Stable with Android Version 10QKQ1.My phone is not yet rooted and now he is encrypted.The recovery is now Mi-Recovery 3.0

I have unlock again my bootloader.

Now to follow your instruction,i should flash the latest TWRP.

I have take TWRP-3.6.0_9-0-berylium in your guide.

I think i should do Fastboot Method because i'm now in Mi-Recovery?i'm right?

No problem with the encryption?

Thanks.
[Xiaomi Poco F1 Questions & Answers] devil1:
i have find this video.This is not the good phone but i think that the installation is the same:
[Xiaomi Poco F1 Questions & Answers] Retrial:
Yes use Fastboot Method to flash TWRP. No problem with encryption.

After that follow my clean install custom rom guide to flash the ROM you want. Also please check the instructions in the threads of ROMs you want to flash. A12 crDroid and PE use their own recoveries.

Basically tell me which ROM you want to flash to help you exactly with steps.
[Xiaomi Poco F1 Questions & Answers] devil1:
Hello retrial,

i have a problem to install TWRP-3.6.0-9-0 on my pocophone.Everything working fine but in step 8 of your guide,i can't find my twrp.img that i have copied in 2 different case to test :

8. Boot into Recovery by typing in cmd: fastboot boot <recovery_filename>.img (The file may not be named identically to what stands in this command, so adjust accordingly and write the full path of it, check the example below).

This command will not flash permantly the recovery, it will just temporary boot into it and afterwards you will flash permantly the twrp.img you copied into your Internal Storage or SDcard in recovery partition.

For example: fastboot boot C:\Users\Retrial\Desktop\twrp-3.5.2_9-0-beryllium.img

Have you an idea to why i cannot find my twrp.img in the boot mode?
[Xiaomi Poco F1 Questions & Answers] Retrial:
Send a screenshot what you type in cmd and where you have the twrp.img

Or you mean you can't find it in your device while you are booted on TWRP?
[Xiaomi Poco F1 Questions & Answers] devil1:
i cannot find the twrp.img in my device.The step 8 of your tutorial.

I have copied the files but cannot find it in the cases.I have take TWRP-3.6.0-9-0

The link of the files: https://eu.dl.twrp.me/beryllium/twrp-3.6.0_9-0-beryllium.img.html
[Xiaomi Poco F1 Questions & Answers] Retrial:
Are you sure you select Install Image?
[Xiaomi Poco F1 Questions & Answers] devil1:
ok i have download an other twrp.img and this time it's ok.i can go to the end of the tutorial but when i reboot my device mi-recovery 3.0 come back.I have tried 2 times but all the time mi-recovery3.0 come back

Have you an idea?

Should i take a additional command like in the video i have send you in the thread "fastboot flash recovery"?

View attachment 5549731
[Xiaomi Poco F1 Questions & Answers] Retrial:
I have all the steps on my guide. Please read it carefully. It boots back to mi recovery because you haven't flash TWRP yet just booted into. After boot into TWRP u need to flash twrp in recovery section so it will stay after reboot.

Please read the steps.

Download portable Minimal ADB and Fastboot and latest Official TWRP recovery.

Open cmd from minimal adb and fastboot and write:

fastboot boot and the path you have TWRP.

Example:

fastboot boot C:\Users\Retrial\Desktop\twrp-3.6.0_9-0-beryllium.img

Then proceed with the rest steps in my guide. Connect ur device to pc while u are booted into TWRP and copy TWRP.img to your device. Then in TWRP press Install Image and select the twrp.img u just copied into ur device. Select recovery and done.
[Xiaomi Poco F1 Questions & Answers] devil1:
I have made a video to show you what happened (sorry for the bad quality and the moove) :

I think a video is easyest to understand my problem.For information my bootloader is unlock and usb debugging ok.
[Xiaomi Poco F1 Questions & Answers] Retrial:
Hmm strange, probably of MIUI. Anyway since you are going to flash custom rom, when u flash twrp in recovery go back and select wipe and wipe everything (read my clean install guide), go back press format data type yes, and then reboot to TWRP.

EDIT: I just saw u rebooted to system. That's not what we want. Press reboot to recovery.
[Xiaomi Poco F1 Questions & Answers] devil1:
i reboot first to bootloader after have flash the twrp.img in recovery.That's only the second time that i reboot to system to use the normal mode of the phone and reboot after to recovery mode to show you that mi recovery is back.
[Xiaomi Poco F1 Questions & Answers] Retrial:
The TWRP flashed correctly. You overlap it again by pressing reboot to recovery from MIUI updater.

Don't do that...do the combination to boot to TWRP after flashing it. Power+Volume Up.

And continue with clean install steps in my guide to flash custom rom.

In my guide I write nowhere to boot to MIUI and press from MIUI Updater reboot to recovery, please stick to my guide and you will be fine.

[Touch Pro, Fuze General] r603:
Is there anyway to change the volume display, or decrease the amount of time it stays on the screen?

When I change the volume in the middle of a call, or game, or whatever... the volume display stays on the screen for what seems like an eternity. There's also no easy way to get rid of it. Hitting the back button takes you back from wherever you were... not just back from the volume display. I find it very annoying.

(I did a search for this topic and didn't find anything... if this has already been discussed, than sorry for the extra thread...)

Thanks-
[Touch Pro, Fuze General] mtem1985:
Maybe it's a solution to hit anyplace on the screen where no button or volume slider is (standard the grey area) it shuts down the volume display only so you'll return to the place where you pushed the volume button
[Touch Pro, Fuze General] r603:
That was waayyy too easy!

Thanks-
[Touch Pro, Fuze General] SquidgyB:
Personally I don't like the HTC volume control, or the System Status screen, I prefer the to have WM deal with them, and just give me the bubble with volume sliders/comm panel links...

You can disable the system screen through the TouchFlo settings in Start > Settings > System > TouchFlo but you need a cab file to remove the volume control, I have it as "Remove-Htcvolume-by-HellengreeN.cab, I'm not sure where I found it.

It's a little glitchy when changing volume in a full screen app, as the bubble/volume bars are drawn "through" the full screen app, but you can see what's going on and it negates the need to use the stylus at all.
[Galaxy Tab S2 General] Akipe:
Hello,

For those interested in the original kernel source code for the SM-T813 :

As I am learning how to make ports for Android, I am trying to train on the original sources of the Linux kernel for the SM-T813.

After several weeks of research, I couldn't find the origin of the different kernel repositories.

Also on https://opensource.samsung.com, it was impossible to find the sources. So I contact them at the end of January to have an access to this sources...

... And they are now available !

You can download them on https://opensource.samsung.com (search SM-T813 at mobile phone on release center) or on my repository at https://github.com/Akipe/android_kernel_samsung_gts210vewifi_original_samsung

It is based on the T813XXS2BTK3 firmware with Android 7 Nougat.

I will see to ask for sources of similar tablets.
[Galaxy Tab S2 General] Pawel_:
Will this help with porting new Adnoid version to these tablets?
[Galaxy Tab S2 General] Akipe:
I don't think so,

Kernel sources for this tablet already exist, and are ported to newer versions.

It is more useful for those who want start from scratch, and want to inspect the unmodified source code.

But my goal would be to successfully create from scratch for the SM-T813 LineageOS 14.1 (Android 7); and then try to move to the latest versions.

Since I am a beginner, I still have a lot to learn, and I don't have much time, so we will see ;)
[Samsung Galaxy S22 Ultra] EmilZackrisson:
I got my new S22 Ultra this monday and I have been having quite a lot of problems with it.

The battery life is terrible, only around 2-3 hours of lite use. Snapchat is near unusable because it is terribly slow and laggy to use and the viewport in the app has a delay of 2-3 sec.

No software updates has come out, and no app update has fixed it.

Any suggestions of how to fix this?

[Samsung Galaxy S22 Ultra] lucky_strike33:
Probably got a lemon
[Samsung Galaxy S22 Ultra] varcor:
Now that the S22 Ultra is in users hands we're seeing big differences between what Samsung has touted and actual performance. Charging times aren't much better at 45W. 1 hour, 3 minutes at 45W for full charge compared to 1 hour, 6 minutes at 25W. Barely any advantage. Also, the S22 Ultra doesn't come with a charger. A 45W Charger will cost around $35 USD.

Even worse, tests reflect a big difference in battery life. The S22 Ultra drained after 8 hours, 50 minutes whereas the S21 Ultra lasted 11 hours, 25 minutes. The S22 Ultra may improve over time with an Adaptive Battery but if it doesn't improve much this is a big issue. The S22 Ultra is looking less and less like an upgrade.

I think we are forgetting the basics of threads like this one:

Which exact model are you using?

Software version, build number, etc..

That kinda helps other users see if they have similar issues on the same device or if it's limited to specific regions..
[Samsung Galaxy S22 Ultra] Paul_Deemer:
I been seeing some tests done on various sites showing that the S22 Ultra Exynos version is very similar to the s21 Ultra in terms of bench scores. Battery Life is worse than the S21 Ultra and of course the Snap Dragon version is faster as it has been in the past. But don't take my word for it do a search on Google. The results are there. Glad the U.S. version is the Snap Dragon. But still not fair to those getting stuck with the Exynos version. This was a big problem with the S20 Ultra Exynos version as well.
[Samsung Galaxy S22 Ultra] Nghtmare:
Keep in mind that Samsung launched a new 45w charger, the previous one had issues with thermals. The model number for the new one is EP-T4510XBEGGB.
