[OnePlus 3 Guides, News, & Discussion] Bradl79:
I have come across an issue with the latest SuperSU and Nougat for the OnePlus 3 with those apps not seeing root and to fix...

u will have to get the su file from the lastest SuperSU zip in the arm64 folder and use twrp's file manager to copy file to system/bin folder, make sure u mount system in Advanced 1st.

Thanks to [MENTION=5624762]matze19999[/MENTION]
[Xiaomi Mi 4C] Cozzmy13:
Haven't managed to test if it fixes the bug because I had to sleep lol.

https://github.com/Demon000/libra/commit/b5067833797cd1eb207cd976bf2419c58ca8c7ed

If anyone can test if it works, I would be very thankful.

How I did it?

Get a hex file editor.

Compile kernel with old touchscreen firmware.

Open the synaptics_biel_sharp_update.fw or synaptic_biel_auo_update.fw that have been generated in firmware/ folder in the hex editor.

Get the MIUI kernel, split it, uncompress it.

In the .fw files, the first four hex groups are magic numbers(a hex group looks like "3F"), and after that there are some common hex groups in sharp and auo firmware.

Use the hex editor to search for the common groups in the MIUI kernel, and also find the magic number before the common groups.

Use the "csplitb" program to split the the kernel binary at the newly found magic number + common groups, and strip the result to 12661 lines.

Repeat this for every common group found.

Then use the objcopy program inside the toolchain to convert the binary files to .ihex, and replace the ihex files in the firmware folder.

Done.

It is complicated, but once you get the first steps it will be easy to understand.

Although I don't know if I did a good job at explaining.
[Xiaomi Mi 4C] Vlad Paul:
Cozmy, you are magic. Lot of thanx, Man.
[Xiaomi Mi 4C] Harrynowl:
Many thanks. :good:
[Xiaomi Mi 4C] danbrown162:
How does one flash this?
[Xiaomi Mi 4C] predragiPredrag:
You cannot, devs that make custom roms can use it to build rom with fixed display firmware.
[Xiaomi Mi 4C] Harrynowl:
I can post a kernel build with it later, not tested as currently I'm working on lineage os using all the vendor binaries and blobs from the nougat release.
[Xiaomi Mi 4C] Cozzmy13:
I couldn't get it to update the firmware because I was not using Xiaomi touchscreen drivers in my kernel, but the firmware itself should be working fine.

I don't want to bloat my CAF touchscreen driver so it will take me longer until I find where it fails.

Please keep us updated.
[Xiaomi Mi 4C] Cozzmy13:

Kernel image which fixes the touchscreen problem.

PS. This kernel may use more battery, just because I didn't spend time optimizing the kernel, but rather optimizing the source-code quality, lol.

You can try flashing your original kernel to see if the fix remains.

Tested on Resurrection Remix Nougat.

EDIT: I haven't tested it on any AUO panels, as my phone has a Sharp one.

EDIT2: Flashed back the Resurrection Remix kernel and touchscreen is still fixed. Success!

Guide: backup your kernel, flash the kernel I provided, restore your old kernel.

Proof as attachment.
[Xiaomi Mi 4C] solis_f:
I hope this gets implemented on next releases of our roms
[Xiaomi Mi 4C] Cozzmy13:
Just give the ROM maintainers a link to this, they will surely add it to the ROM.
[Xiaomi Mi 4C] Phlogistol:
Holy **** :D You're a hero Cozzmy13, thank you! :)

I just tried the image on my AUO Mi4c, and I couldn't boot TS CM13 with the kernel. The fix didn't stick after restoring the original boot partition, but I have a feeling we're very close here :)

I'll try flashing RR later and see what I get, I have a Nandroid backup somewhere.
[Xiaomi Mi 4C] Cozzmy13:
It's my fault, I compiled the image with RR ramdisk. It definitely works on RR Nougat, that's for sure. I have since switched to Lineage OS and the fix sticked.
[Xiaomi Mi 4C] bankov:
I have problem . Ive installed the fix on AICP 12.1 the phone doesent boot. Returned the old kernel from backup. My phone boots but now i have problem with my hardware buttons, sometimes take 3-4 to respond to the touch. I also deleted and flashed system partititon but problem stil presist.
[Xiaomi Mi 4C] Cozzmy13:
Is the touchscreen problem fixed? If it's not then this is not my fault. If it is fixed then it's XIAOMI's fault. I will test on my device and report back. Use on-screen buttons until I do some research.
[Xiaomi Mi 4C] bankov:
The problem was not in your update. It was from the last AICP update 23.01.2017 i installed 19.01.2017 and buttons are fine now. The touchscreen seems to be fixed iven with full wipe, going back to miui and restoring 19.01.2017 AICP.
[Xiaomi Mi 4C] Phlogistol:
Well, I just installed RR on my AUO mi4c, and it doesn't work. The touchscreen is broken and registers touches consistently but strangely. It even does it in recovery. I'm trying to restore my backup now.

EDIT: backup restored. Still don't know why the firmware didn't work :(

bankov, which flavor of mi4c do you have? Sharp or AUO?
[Xiaomi Mi 4C] Cozzmy13:
Can you explain the problem a bit more?

Did it get fixed after restoring?
[Xiaomi Mi 4C] bankov:
Mine is AUO. My touchscreen was like yours but it was from AICP update.

Basicly im not 100% shure it is fixed but i remember it couldnt register touch on the left bezel if somhere else is toched on the screen. And now is fine.
[Xiaomi Mi 4C] Cozzmy13:
For anyone applying this from now on, the process is not reversible, because of the way the driver checks if firmware can be updated, it only wants to do upgrades, not downgrades.

Also, for anyone having problems that go away after a clean flash, they are probably not because of my fix.

If they don't go away, there is probably an updated firmware version somewhere that fixes it. I'll extract them again from the newest Nougat version.
[Xiaomi Mi 4C] Phlogistol:
Sure, I was a bit pressed for time yesterday :)

The touchscreen was inconsistent, for lack of a better word. Touches on a specific point on the screen didn't register on that location, but on some other one. It wasn't random because I could reliably reproduce this. There were also some points on the screen I couldn't reach at all. The capacitive buttons also didn't work. I'd have taken logs, but I couldn't get into developer options :(

I don't know exactly how this works, but the touchscreen got reversed to its original state when I managed to restore a backup of my earlier TS CM13.1 system from TWRP (I restored all available partitions). It took a few tries because of the weirdness though :) When I say original state, I mean it still suffers from the multitouch bug, so nothing got fixed.

Hope this is useful, but I'm stumped. Could we have different digitizers?
[Xiaomi Mi 4C] Cozzmy13:
Well, this doesn't seem to be a problem with the fix. Since the firmware gets flashed on the actual memory of the touchscreen and the touchscreen driver can't downgrade it, the problem must come from somewhere else.

We currently can't extract the firmware from a running device, so I can't analyse what firmware you have installed now. I'll work on the problem more when I have time, as I'm busy with school now.
[Xiaomi Mi 4C] Phlogistol:
Well there's something strange going on, because I flashed a touchscreen fix and the touchscreen went wonky :)

I'd try playing with this more, but I don't really feel confident in my low-level Linux knowledge to explore this.

Thanks for your effort Cozzmy, it's greatly appreciated, we'll get to it someday :)
[Xiaomi Mi 4C] Cozzmy13:
Maybe you have a different touchscreen, I don't know. I only extracted the Sharp and AUO firmwares, but there were more which I thought are not used. Maybe there are. I will extract them all, but in my kernel I only added support for Sharp and AUO so this will take even more work. Currently I'm really trying to optimise it, as I'm really happy that I barely used any Xiaomi driver modifications. I'm doing this to get accustomed to working with the kernel source code, it's a really good skill if you are going to work as a sysadmin.
[Xiaomi Mi 4C] Phlogistol:
It's possible, although all the info apps I've tried say it's an AUO panel. I'm attaching an AIDA64 screenshot. I can't find any info on the actual touchscreen used though :(

I've also tried installing a newer MIUI version before, and the touchscreen was fixed in it -- the multitouch worked properly at the edges. It never sticked though, after reinstalling RR and then CM13 the fixes disappeared, so I presumed it's a kernel thing.

You did a great job, but seems the problem is a bit more complex than we figured :)
[Xiaomi Mi 4C] Cozzmy13:
My assumption now is that the kernel does downgrades only on AUO panels, so something must be wrong somewhere. Probably the open source AUO firmware is recognized as a newer version. I'll compare them and report back.
[Xiaomi Mi 4C] Autines:
Nice work! Thanks man.

I'm confused how can I fix it in newest MIUI Dev rom without root,you know I use mouse via otg right now.its hard to operate without touchscreen ?
[Xiaomi Mi 4C] celrau:
This is an old thread but...

I'm having this touchscreen (sharp) issue with any rom only when the device gets hot. Touches are totally random or if I keep my finger on the screen it acts like multiple touches. When the screen is cool I have none of that.
[Xiaomi Mi 4C] Cozzmy13:
It's a hardware/touchscreen controller firmware calibration problem, I get the same sometimes. We can't fix it.
[Xiaomi Mi 4C] celrau:
So I guess the trick is to keep the CPU from getting hot.
[Xiaomi Mi 4C] Cozzmy13:
Yeah, probably.

[OnePlus X Q&A, Help & Troubleshooting] Im_Mattgame:
Hello,

I've been experiencing a strange problem with my OnePlus X

This problem comes back regardless of ROM. Data will work fine for a while but at some point (haven't found what causes it), data will stop working completely. A SOFT Reboot won't fix the problem. I have to do a FULL reboot.

I tried on two completely different 7.1 roms but no else reported the same issue.

Thanks in advance guys. Getting desperate

Downloading the proper firmware from SamMobile -> https://www.sammobile.com/firmwares/database/SM-G930U/

Flash the firmware via odin (you can use the same method found here: https://xdaforums.com/s7-edge/how-to/official-stock-firmware-update-odin-t3335065)

I just did this recently to switch from SM-G930R4 to SM-G930V

Note, you will lose all data on the phone if you try this.
[Verizon Samsung Galaxy S7 Questions & Answers] nrage23:
Go to Updato.com and get the newest SM-930U firmware from January and flash via Odin. The 930U firmware you flash must have a bootloader the as or newer than your current firmware or it will not boot. You do not have to root to update via Odin.

Also it unlocks the LTE bands Verizon has Disabled. And Disables the Hotspot Lock.

Yes jedi the built in Caller ID is deffinitly cool.
[Verizon Samsung Galaxy S7 Questions & Answers] JediDru:
Bootloader is locked because it is a snapdragon variant. Only downside is can think is you would have to pay your bill in store or on a PC. Lte seems the same. Yes if nougat is on. You just load up the most recent U firmware and flash over nougat in odin.
[Verizon Samsung Galaxy S7 Questions & Answers] SDRebel:
it shoudl be simple...but it failed for me in one of my two phones. now it keeps going to recovery (downloading the original firmware to reflash it). the one that worked was a SMG930VZDA (made in vietnam) while the one that didn't is a SMG930VZKA (made in korea). I hadn't updated either one from the original firmware, but not sure what firmware they came with....

so if it works, it's great, but if it fails...
