[Xiaomi Mi 4C] Aevum:
The overheating is caused by a ****ty rom some vendors use,

Install the latest recovery, and do a full advance wipe (everything except OTG USB), then do the format,

DO NOT REBOOT the phone, connect it to the PC and copy over the latest miui weekly (i used 6.9.1) and flash it, then see if it keeps overheating.

Apparently some of the malware some vendors install are hard to get rid of, i had weekly, monthly, slim6, Teamsuperluminal and Omni rom installed, and they all showed the same issue. it wasnt until i did this "sanitation" process i managed to get rid of the heat issue.
[Xiaomi Mi 4C] Danny94:
You found some way to hard mod it ? =) The snapdragon 808 would be very powerful if there aren´t that overheats.

Making some holes in the back cover (get out hot air) or give more space (case is extremly tightly built) ? A heat pipe (passive cooling)?
[Xiaomi Mi 4C] Ydraulikos:
Things are a lot better using an undervolted kernel. Built one from kuma sources (not for MIUI), I could share if you want.
[Xiaomi Mi 4C] kar5ten:
nice idea with passive cooling ;)

i glued my nhd 14 to the back that helped ;)

no serious i dont have any clue to make the phone cooler with hardware modifications.

without the backcover it isnt cooler. the difference isnt noticable.

i would say how the cpu is build into the phone is wrong.

for me the phone isnt worth it anymore. im moving to a BQ or the HTC10.

why should i use a phone that i have to downclock to a fraction of its performance ?

or i use normally and get throttled after 20 minutes?

and it doesnt matter which os i use any miui or cm version suffers from overheating.

so i think ether xiaomi make mistakes while building the phone or it is just the bad 800 series.

but looking at the lg g4 the picture is the same. so qualcomm is to blame for it.

sorry for this but the only solution is to use a fan on the back OR the better solution buy a better phone ;(

edit:still finding grammar fails
[Xiaomi Mi 4C] Ydraulikos:
For anyone willing to try this is an undervolted kernel based on kuma's sources and a modified msm8992-regulator.dtsi with lower ceil voltages.

Tested only on CM13 but should work for other ROMs based on CM13. It can make your phone unstable (freezes, crashes), so before you try either keep a backup of your current kernel or simply boot (don't flash!) the kernel to ensure that everything works normally:

fastboot boot undervoltedk.img
[Xiaomi Mi 4C] Danny94:
[MENTION=5532654]Ydraulikos[/MENTION]

im already using a kernel from kuma (Resurrection Rom) and yeah its very great, less overheating. The Rom itself is slim for less heating too.

But its overheating though while playing 3d games for a longer time.

[MENTION=4831564]kar5ten[/MENTION]

..nhd 14.. that would look funny xD.

Yeah the problem is the cpu. Snapdragon 808 and 810 suffering from overheating, 810 more.

But xiaomi could handle this too. Not use this cpu or built better cooling system, instead make it as thin. The most temperatures i have is on the top right. If they used passive cooling like pipe heats for distribute the heat, we don´t have this problem or rather less overheating.
[Xiaomi Mi 4C] kar5ten:
[MENTION=5532654]Ydraulikos[/MENTION] thanks i will try this.

[MENTION=4488955]Danny94[/MENTION]

i made another test.

i use resurrection rom 5.7.1 with oc kernel 1.12 (intelliactive gov.) custom temp. throttle at 75 C

i opened the back and added aluminium foil .

10 layers on the upper side where the cpu sits and 6 layers above the battery and the cpu. they both are connected.

now i run antutu 3-4 times and i got these results

75899-74012-70371-68155

with max temp of 53 C after those 4 runs.

the idle temps are now at 30 -35 C most time

but i only tested it for 2 hours
[Xiaomi Mi 4C] Danny94:
[MENTION=4831564]kar5ten[/MENTION]

oh nice that sounds like a good idee! And withouth foil wich results you get, antutu - temps ?

The Alumiunium foil could take the heat from the cpu and distribute it over the device, for better result thermal paste as connection between cpu and foil could help.

Maybe with another material (foil) you could improve it as well. The best result you would get maybe if the backcover consists of metal, this way you could get the heat out of the phone, air cools metal. (problems.: back cover can get hot, you can heat back cover with hands[maybe a case])

Care about that foil doesn´t heat up the battery and the metal can disturb radio signals (gps wifi mobile data).

Could you share a picture as well of your modified version here in the forum, maybe one too please how it looks inside. At the moment i don´t have a plan how to open the back cover. =)
[Xiaomi Mi 4C] kar5ten:
I will post some pictures but next weekend. Before I open it again I want to test it.

I don't know the exact results from antutu before I modded it.

First 75k

2nd 60k

3rd 55 k

At the moment I didn't noticed any signal drop or something.
[Xiaomi Mi 4C] patadas:
Hi,

Did you have the opportunity to take some pictures of your mi4c modding?

would be also great to have a slight bigger case it probably help with the overheating.

best regards,

John
[Xiaomi Mi 4C] kar5ten:
[MENTION=7590612]patadas[/MENTION] I get a new case this weekend. Then I will take some photos.

But the problem is to open the phone
[Xiaomi Mi 4C] patadas:
To open the case i have found a video, see the video and tell me if the video does help in anything?

[YOUTUBE]T8j-n7ZhkyA[/YOUTUBE]

by the way : Xiaomi Mi4c Teardown

http://www.myfixguide.com/manual/xiaomi-mi4c-teardown/
[Xiaomi Mi 4C] kar5ten:
you should try the way it is shown in the video !

i ripped my own open with some small screwdrivers. i cant recommend it. but with the creditcard it looked good
[Xiaomi Mi 4C] patadas:
At this moment i don't have much time to do it so, but in November i want to do some small holes in back case near CPU.

And I am also interest in our modding method.
[Xiaomi Mi 4C] Danny94:
Hmm i don´t think it will help much to make small holes in the case, because there is no air exchange. Like kar5ten said you need a fan for do this.

kar5ten idee with the aluminium foil would help much more. Use thermal paste for better results. But the problem is that there is no air for cool the aluminium foil. Could be that it just delay the overheat.
[Xiaomi Mi 4C] patadas:
Hi,

I believe that aluminum foil will help distribute the heat through the back case. The aluminum foil will increase the heat exchange and eventually the case will cools faster.

I also think that the holes in the box will allow some heat that are retained by the plastic case will be released.

Maybe these modding can help to cool the mobile phone in 1 to 3 degrees or more I really do not know.

But it is necessary to test to know if in fact does help with the overheating issue.

anyway I agree that the optimum would be to have an air circulation.

In my case, I set the thermal engine to significantly reduce the frequencies with the increase of the temperature.

best regards,

John
[Xiaomi Mi 4C] Danny94:
A good solution to test would be a back cover as metal. Connect cover and cpu with thermal paste and you would have a real nice passive cooling. Like written some posts before. That would help really much. But how i said the cons, the backcover could get hot/ you can heat the back cover with you hands.

Small holes withouth air circulation won´t bring a single degree cooler. Air circulation we would never had =) A fan on a mobile device is cancer xD

But i think the idee from kar5ten could help as well. With optimzied software and his mod overheat could be gone.

Lets wait for his reports this weekend.
[Xiaomi Mi 4C] patadas:
yep, lets wait.

I'm just thinking out loud, a custom case made with a 3d printer slightly larger with a metal inside connecting to CPU to metal with thermal paste.
[Xiaomi Mi 4C] Danny94:
And some larger holes in the plastic case for air cooling metal behind ;D. Top would destroy the cons i mentioned and won´t look as bad.
[Xiaomi Mi 4C] patadas:
Anyone here works or study in place where there is a 3d scanner?

to do a 3d scan of a mi4c back case.
[Xiaomi Mi 4C] Danny94:
[MENTION=4831564]kar5ten[/MENTION]

waiting for your report ;D. How does it look like ? Less overheating ? Does you have some free time for any photos ?
[Xiaomi Mi 4C] kar5ten:
Sorry that I couldn't answer the last week.

So I tested it a bit more.

I opened the back and took put the aluminum foil and it made almost no difference. Maybe 2-3 C.

At the moment I have a back cover that cover only the back and the sides.

I put some layers of alu foil inside.

This is the only method I can recommend.

To open the back cover needs some time and if you are unlucky like me will scratch your back plate
[Xiaomi Mi 4C] stillsober:
Is the back glued? Did you use hairdryer?
[Xiaomi Mi 4C] kar5ten:
I just use some tape for a fixed position.

This one was my cover.

For the inside is used some foil as well but only in the upper half.

Also I bought a new one and selled the mi4c.

I now have redmi note 3 pro SD (kate).

It has a body of Aluminium.

The only bad thing is the camera.

But here is a temperature comparison. In °C

Unlock the device

Mi4c - 30

RN3 - 15 - 30

Normal use

Mi4c - 35 - 45

RN3 - 30 - 33

Gaming/other heavy stuff

Mi4c 50 - 75(highest I seen ~85)

RN3 ~ 37 (highest I seen while charging and gaming)

Antutu

Mi4c - 75k after 4 runs down to 68k

Rn3 - 78k after 4 runs down to 75k

I think if they used a metal case the 808 should be cool enough for normal use. Sure the 650 doesn't suffer from overheating like the 808.

If I only had the mi4c camera.
[Xiaomi Mi 4C] Danny94:
If we could get a heatpipe like fujitsu made it problem would be solved.

http://www.fujitsu.com/global/about/resources/news/press-releases/2015/0312-01.html

I would like to use a heatpipe but i can´t find a site to buy one.

Then i will try graphite sheet, has a much higher thermal conductivity then aluminium.

https://www.aliexpress.com/item/200...65.html?spm=2114.13010208.99999999.264.8RyZ0I

^^ i didn´t test this yet but i will order.
[Xiaomi Mi 4C] kar5ten:
Maybe you can try a peltier component?
[Xiaomi Mi 4C] Danny94:
[MENTION=4831564]kar5ten[/MENTION]

hmm thats too thick i think. Maybe withouth the back cover.

I would say Graphit foil can do a good jop. I think about to make a thin hole on the side of the cover to get the graphit foil out of the device, so the air can cool it. (It´s important to get the heat out of the device)

With a good thermal engine and a modified governer i aim constant 65k antutu withouth overheat (~45 °c). That would be a nice result.

Edit:

Picture:

like that somehow =) Sorry for that bad draft ;D. Just for better understanding.

Edit2:

I´m using a case always, so no problem.

Edit3:

but earlier before i make a hole i try otherwise (can´t sell it well with a hole xD). Pictures and reports in 1-2 months.

Edit4: Well now i recieved the Graphit foil, i made an own Thread: https://xdaforums.com/mi-4c/general/mi4c-overheat-hardmodding-passive-t3532565

Hello, im using O+ 3 and just installed the Oxygen 3.2.2 OS

I wanna root it but got problem because my ADB says unauthorized

Ive already tried to dig some similar case and possible answers thru the internet but none of them work for me

Ive tried to enable disable the debug permission

I also already make sure my ADB is the latest one.

Also already try to delete the 'adb_key' files from my PC (im using windows 7 64bit)

The problem is most user which has similar problem with me got the 'authorized debug prompt' popped up again on their phone, but its not working on my phone.

It appear only one time at the very first time i connect it to my phone, but i accidentaly click 'cancel' on that prompt

But after that it never re-appeared again.

Can someone kindly help me? Thanks a lot
[OnePlus 3 Guides, News, & Discussion] speedyjay:
Install the Android SDK or install the OnePlus 3 drivers
[OnePlus 3 Guides, News, & Discussion] toughkid:
What does the Android SDK do mate?

I never used it before, so would be great if u can give me some hints

Thanks :)
[OnePlus 3 Guides, News, & Discussion] tdamocles:
Make sure debugging is clicked on under developer options in the main menu. Then disconnect the phone from the pc and reboot the pc. Reconnect the phone after it reboots and hope that you get the adb prompt on the phone again.
[OnePlus 3 Guides, News, & Discussion] Le_Zouave:
android sdk have the latest tools including latest ADB. There is ADB standalone install, that means that if you tell us that you have the latest ADB, that only mean that someone extracted the ADB and lastest fastboot and did a repack and in the end it's not an official repack.

but "disable the debug permission" reset all the recorded device for debug so you should have another prompt.

If in the end you don't have another prompt, verify you adb version by installing the lastest android SDK, uninstall and reinstall the oneplus drivers.

Then if no prompt there is 2 choices :

- wipe the phone, it will reset the prompt for sure, 100%

- use another computer (well you have to have another computer).
[OnePlus 3 Guides, News, & Discussion] joho5:

[OnePlus 3 Guides, News, & Discussion] toughkid:
Then how's in the end it goes mate? Do you root your phone? I just wanna root it, if u got any other way except the adb that would be great tho
[OnePlus 3 Guides, News, & Discussion] Hw4ng3r:
Have you checked all of your USB ports? I know in the past (with other phones), problems arise if you're not using a direct USB port (one soldered into your MoBo).
[OnePlus 3 Guides, News, & Discussion] dewri21:
Go to Control Panel > Hardware and Sound > Device Manager > expand Universal Serial Bus controllers. Now connect your phone. You'll now see USB Mass Storage Device. Right click on it. Select Properties, then go to Details. In the Details section, under Property, select Hardware ids. You'll then see the device id. It will be shown something like this: USB\VID_2A70&PID_9011&MI_01. From this you have to take the 2A70 code ~ the code between the first _ and &. Now go to desktop and create a new text document and copy paste this using your device id as shown:

# ANDROID 3RD PARTY USB VENDOR ID LIST -- DO NOT EDIT.
# USE 'android update adb' TO GENERATE.
# 1 USB VENDOR ID PER LINE.

0x2A70

Now open the Save As menu. In Save As type select All Files. Save the file as adb_usb.ini

Copy this .ini file from desktop and paste it in C:\Users\YourPCName\.android

Disconnect your phone, reboot your pc. Now with USB Debugging turned on, connect your phone to your pc, you'll surely get the permission thingy popup in your phone.
[OnePlus 3 Guides, News, & Discussion] Wombosvideo:
For completion:

If you DO NOT have access to your phone for any reason but still want to use ADB you can simply boot your phone into TWRP and follow these steps.

Windows:

1. Open %userprofile%\.android

2. Copy "adbkey.pub" to your phone (adb push %userprofile%\.android\adbkey.pub /sdcard/adb_keys)

3. Switch to your phone.

4. Go to Advanced > Open Terminal

5. Type in "stop adbd"

6. Move "adb_keys" from /sdcard to /data/misc/adb (mv /sdcard/adb_keys /data/misc/adb/adb_keys)

7. Type in "start adbd"

8. Switch to computer

9. Type "adb shell setprop persist.service.adb.enable 1"

10. Type "adb shell setprop persist.sys.usb.config mtp,adb"

11. Reboot your phone - DONE

Linux / Maybe Mac:

Same steps, but use "~/" instead of "%userprofile%"

Please note:

You may have to repeat the steps 1-7 after boot when still not having permissions so it makes sense to use cp (copy) instead of mv (move) and only repeat steps 5-7.

Edit: Please also check if your drivers are all installed and enabled.

The smali files in settings zip were creates by an older version of either apktool and/or smali and/or baksmali, so you need to use similar version to decompile your settings, and to recompile when done, (unless you're a smali pro and you can convert them).
