Hello XDA forum wanderers .
I use my Samsung galaxy tab s7 SM-T875 for heavy gaming and i am having a problem with it : thermal throttle.
I have looked everywhere with no avail, tried many mods but it just doesn't work.
Is there a way to remove thermal throttle or at least edit the .config (no idea where it is at) file to control the values or something.
I am very well aware of all the problems that might be caused because of this manipulation. So i would like a point of return if possible (backup the file somewhere or something, i dunno)
I am in Android 11 and i am stuck with it so going back to A10 and using another kernel is out of the question
Also my device is rooted with no problem, using magisk latest version.
Many thanks in advance fellow root adventurers.

Hi folks
As mentioned in a thread I posted a couple of weeks back (http://forum.xda-developers.com/showthread.php?t=1207476), Samsung have very annoyingly blocked WiFi channels 12 & 13 on US-originated Tab 10.1s with their latest TouchWiz UX update.
I've got a Tab that I had been using quite happily on chan 13 (minimal interference from neighbouring WiFi APs), but after the updated it wouldn't connect at all, yet could see other networks. Moving the AP channel down <12 solved it, but this only works for my home AP that I have control over. The one at work is on either 12 or 13 and therefore now isn't visible.
The guys at PC Pro have tried their UK-purchased Tab 10.1 and it's working fine, so it seems to be just with the US ones that Samsung have blocked this.
I've logged a support request about it but don't hold out any great hope of them fixing it.
I was therefore wondering if anyone could think of a good way to re-enable this. Do the Tabs had a modem/radio type bin that could be flashed along the lines of the SGS II? If so would this do the trick or are chans 12/13 being blocked elsewhere?
Thanks for any suggestions - as you can see at http://forum.xda-developers.com/showthread.php?t=1223978 I'm not the only one who has run into this problem!
(PS - have already tried a full factory reset before anyone suggests it )
What about flashing a Euro rom, would that then enable the extra channels?
That's the kind of thing I was wondering about, but wasn't sure if it would work or not.
My model number is GT-P7510UWYB and it's 16GB WiFi only model.
Do you think it would just be a case of getting hold of the stock August update for a UK device (and if so, any links? ) and installing it via Download mode/Odin or would it object to that saying it's not a valid ROM for that model?
I don't know I.f there's a newer rom than those shown on the samfirmware site, someone with more knowledge than me may point you in the right direction.

Moving to Q&A
I've just moved from galaxy S8+ to this forum, and I've got used to make the phone more comfortable for my usage like I used to make a combination of poweramp+viper4Android+dolby atoms having a good music experience , Mtweaks to set the kernel work well for me, after upgrading Oreo, the combination broke and only viper4Android in magisk works ,then I turned to my galaxy S9+ with exynos chipset, I can't imagine custom kernels came so fast after Samsung releasing their kernel source.it seems to be great but to me,I tried some of the custom kernels but only superSU works.
so the 1st question is magisk is no longer capable with this device?
and if I use Mtweak to modify the kernels, my phone reboots, it seems nothing could be changed though it looks like to be able to change,so my 2nd question is am I using the wrong APP to modify the kernels?
and the last question is ,is there any soundmod available for this device? really don't like soundalive,I'll be appreciate with every reply, thanks!
Being a no good dirty cheater, I'm a big fan of Game Guardian and I use it with great success on my HTC U11 phone. I recently discovered that it can be used without root, by using a virtualization environment such as Parallel Space or VirtualXposed. As I haven't rooted my M5 (SHT-09), I downloaded Parallel Space and GG and got it all running. However, I've found that I cannot make any edits to game memory space from within GG.
The are a number of posts on the GG forum suggesting that there is a bug (or security feature) in many Huawei device cores / firmware that relates to the implementation of the ptrace system function call. Something in the firmware seems to prevent the GG process from modifying the child process memory space using PTRACE_POKETEXT or PTRACE_POKEDATA.
The suggestion of the developer of GG is to "change the firmware so that there the ptrace system call works normally".
Anyone aware of this "feature" of Huawei device firmwares? Is there / could there be a solution to modify the firmware to "fix" this behaviour?
I saw you posted on my thread. Thanks for that. I wanted to see whether flashing a different kernel like Serenity would help. But i doubt it. Might be worth a try. Would have loved to know that beforehand. :/ Any other ideas? What I am seeing is that it needs a competent developer to recode the Kernel. I would then flash that patch. Other than that it is defined as unfixable. That we'd have to change the device. :/
It's the main reason that I haven't rooted / unlocked the bootloader, as running GG is pretty much all I use root for on other devicxes. And the fact that rooting / boot unlock kills Widevine level 1 support, which is madness on a 2k device like the M5. Wouldn't want Netflix streaming SD content only.
From what I understand, which isn't much, the issue is buried deep down in the kernel. Not sure if a custom kernel would solve the problem or not. Knowing XDA, I'm sure someone will be crazy enough to try it at some point in the future!

Yeah I get that, but some games dont have a cloud feature. Making parallel space useless. Plus I appreciate some other root features. I have a note 8 which should work GG without root, but I'll see how it goes. Oh really, I'm a big time stream fan. I havent tried Netflix with root yet . Should still work tho. I think. Hmm well, problem is all kernels are made for devices like the mate 10 or the P20. Not sure if they will work with the M5, wouldn't want to brick after all the trouble. [Edit, found the nextflix module apk. Can flash that with Magisk. Makes it work again ]

Alright guys, I found this out today (I'm also Kr1msonReaper on GG forums);
Huawei kernel prevents GG from working in Android Oreo HOWEVER-- If you downgrade to Android Nougat, I find that it works perfectly. Hope this helps!
Just a note, when you are, of course, debloating Nougat, make sure to disable Huawei system update app so you don't find yourself in Oreo the next day.

How do you downgrade to nougat? Any reason not to do it? And will I retain root ?
I actually like Nougat more than Oreo as it fixes issues such as the ptrace error and seems to have more battery optimization. It's been a long time since I downgraded to Nougat and since then I got a new phone but here's the tutorial I followed. @mrmazak has helped me out of se sticky situations and his tutorials have never failed me. https://forum.xda-developers.com/honor-7x/how-to/guide-honor-7x-flash-oreo-update-t3781649/amp/
I believe you will lose root but you can easily flash magisk again after installing the downgrade package.
Hope this helped!

I am not sure this would work on the Huawei mediapad m5 tablet. As far as I can tell it never had a nougat firmware to rollback too. I looked for sht-w09 and the all the files appear to be for Android 8 and none for 7 nougat. Unless I am missing something??
Other than they locked out ptrace stuff and that it appears unlikely to get Android 9 in the US for my mode l its a pretty good tablet. Maybe I should just sell it and move on to a tab s6 that can be rooted.

Hey! You're right I couldn't seem to find a nougat downgrade. On the bright side, I did find a Pie update for your model. Who knows, maybe ptrace will be fixed in that version?

Last September,I bought a new phone called the Kult Beyond and it was a good phone for the Price.It's a little under $100 and myself being a student,couldn't really spend too much over that.Previously,I had an iPhone 3GS which I rescued from a recycling Center for $30 bucks,4 years ago.iOS 6.1.6 Jailbroken and was a lot of fun.But soon enough,I found it to be lacking in many aspects.So I bought this new phone,My first Android phone and I was OK with it for a while,But soon enough,I realized that it's very average and software optimization is kind of missing.3GB RAM and at idle,Only 900MB is free.Then I found it's all that System Bloatware which cannot be removed.I then learned that with ROOT,We can remove them! Also learned that Root can allow to mess with CPU/GPU Voltage and Clock settings which can help with battery life as well!
But I ran into another problem - Media*******Tek.I tried MONTHS of rooting the phone using various methods right from KingRoot.etc and NONE worked.I read that the newer MTK-equipped phones are very hard,near-impossible to root compared to Snapdragon due to many reasons such as the Mass fragmentation of MTK-Based devices.etc
Here is the specsheet of my phone
Device I.D - 33DE8604CFF9E987
Serial Number - K1950A1X77150008
Kernel Version - 3.18.35
MediaTek MT6737 Quad Core 1.25Ghz CPU
3GB RAM,32GB ROM
13MP Front and 13MP Rear Camera with Dual LED Flash
3000MaH Battery
Android 7.0 Nougat
Can anyone here please help me root my device so that I can atleast try to fix the sluggish performance at times due to some unwanted System Bloatware using the Memory and CPU Excessively ? Thanks a lot!

Make sure you have unlocked bootloader before following the steps given in the above thread.
Since you have Mediatek device, you should use the custom boot img method given in the thread.

You will have to search the internet for it. Try androidmtk.com or firmwarefile.com

I was recently gifted a lovely Lenovo Tab M8 FHD tabled, and while the hardware and overall design is very spiffy, Android 10 is absolutely horrible on it. Android 10 is using up massive amount of resources, has some real bad optimization issues and it's just bad in general. I checked the official Lenovo forums and there are tons of threads about how the Android 10 OTA update that was not announced or anything has caused issues with their devices. I read both on there multiple times, and in a thread on here that it's possible to use the Lenovo rescue and recovery tool to install Android 9 through putting the old rom in a folder that has the name of the most up to date rom. I found two separate roms with the same name, if slightly different file sizes while I was combing through the internet, and while I tried to use both to get Android 9 on my device, neither worked. So, I am hoping and praying that someone on xda can give me some badly needed help with a link or even vague directions toward where I can get the firmware I so seek. I am rambling on a bit and I do apologize for that, but I can sincerely say that it would be a big weight off my metaphorical chest if I could get some help with this. Thanks for reading my post. Also, I apologize if I mixed up rom and firmware at times.
Just got Tab M8 FHD and decided to give Android 9 a try since tablet is more laggy than I though.
I got rom from https://mirrors.lolinet.com/firmware/lenovo/Tab_M8_FHD/TB-8705F/
Flashed it with SP_Flash_Tool, using the Download agent MTK_AllInOne_DA_6765.bin (found in the archive with the ROM) (I disabled "Check LIB DA match" in Flash tool options).
Rom TB-8705F_S100099_200706_BMP.zip is Android 9. Got Magisk and EdXposed running.
Maybe it's just in my mind but it does seem faster than Android 10 - well at least when scrolling through menus or browsing Play Store. Overall performance is probably the same so downgrading won't make games / apps run smoother.

After you installed Android 9, did you have to use the disbale vbmeta method like they did in Android 10 to get root or did you have to use another method?
