[G3 General] Kigsuha:
Thank you

do you still get reboot with the copper shim mod?

And is the size for thermal pad the same for the copper shim ?
[G3 General] Racer-1:
Yes, the size of the copper shim is the same as a thermal Pad would be. Maybe a little thicker would work a little better.

No, the reboots are gone. I got a new original battery and now everything works.
[G3 General] Kigsuha:
Okay thank you very much for taking your time to answer my questions .
[G3 General] arebokert:
Just for anyone else wondering, you can't only use a shim. You need paste as well to bridge the gaps on both sides and to ensure proper contact between the CPU and the shim. It's pretty much useless only using a shim and no paste as it's very hard to find a perfect fit, and even if you did find a perfect fit you'd need the paste anyway because there would be essentially no heat transfer without it.
[G3 General] Kigsuha:
Some more questions how much thermal paste do I put for the both sides for the copper shim ?

Thermal paste and copper shim , do they both need to be good quality or one of them can be less good ( cheap) and other good or both ?

Dont really wanna spend more than 10€ if possible.

Thanks again.
[G3 General] Taracair:
I wouldn't save money for that mod. Use top quality materials for that.

Looking forward to do the mod in future also. Not sure when. I think I need more confirmation from people around that everything is fine after few months.
[G3 General] jhonyp:
Ok, i'm doed this mod a week ago, and four days later open my phone again to see if everithing was ok. I notices than metal framework have a dark circle around the thermal, like burned metal.

Next day (three days ago) droped my phone and the result was a cracked screen, so i sell it and buy a new one g3 d850 3gb ram.

This new phone is much cooler than previus one. Why? I dont know
[G3 General] fridaycider:
I did this mod and I now have a dark patch on my screen where the pad is . it is faint but is there.
[G3 General] skui:
Just to let you know... you should put some paste on the cpu first, then you set the pad, thermal paste again on the pad and then you're ready to assemble again the phone.

The paste must be spread inside the cpu edges, and inside the pad edges, not all around them or down to the metal frame.

You should not do this:

Consider that the thermal paste works as a heat conductor, it's not a magic stuff that cools the cpu by itself, and too much of it can results in a bad conduction and so a worst cooling!
[G3 General] cliuc:
I've tried the mod using purely thermal paste without shim or pad.

No dark patches on the screen, runs cooler at the power buttons when running games, but get the feeling some of the heat is transferred to the front now instead (i.e. the top portion screen gets warmer then the rest of the screen)
[G3 General] Racer-1:
That could be because you got a better SoC that needs less voltage for the same clock speed.
[G3 General] Kigsuha:
I undervolt to these values and no change to the heat .

Is it because my undervolt is not working ?

Remix RR ROM with 777jon kernel. D855
[G3 General] fridaycider:
Stupid me left shim in and pad. Too much pressure . all ok now . duhh !!!!
[G3 General] Racer-1:
What's your max clock?
[G3 General] Kigsuha:
CPU0 1113mhz

CPU1 652Mhz

Cpu2 652mhz

Cpu3 652mhz

And still around 50°c in light usage
[G3 General] Racer-1:
Ok, but without a thermal pad or shim?
[G3 General] Kigsuha:
No mod.
[G3 General] Racer-1:
I think you can't expect much without any mod. The heat isn't transferred away from the SoC in any way.
[G3 General] jhonyp:
Maybe. The first one was a d855ar (an international model made in Argentina) and the new one is a d850 (made in korea) so i think materials used in factory can be different.

I feel much more glass screen on d855ar. The screen of d850 feel like plastic. So, are differents.

"Searching thermal pad" on Google didn't gave much of results.

Only notable is the arctic thermal pad but it is too big .

Anyone knows what thermal pad I can buy ? Or will cutting the thermal pad works ? Thanks
[G3 General] liamR:
Cutting will work fine. I bought the 50x50x1mm Arctic thermal pad and cut it to fit the chip.
[G3 General] Kigsuha:
Could you please tell me how you cut it ? Just scissors ?

And do you have a link to order the 50x50x1mm that ships to FRANCE ?

thank you very much.
[G3 General] Racer-1:
Search for a phobya thermal Pad. They are pretty good.
[G3 General] Kigsuha:
Thank you

looks like it is the only choice .
[G3 General] arebokert:
Okay so received the shims today. I got a variety from 0.3mm to 1.5mm thickness, all 15mmx15mm in width.

These were the ones I ordered.

So, I took my phone apart. It was a bit tricky as the plastic panels didn't want to come loose. I used a guitar plectrum and managed to get it off but I really thought I was going to break them when pulling them off.

I took some pictures as requested.

Here are the pictures of the 0.5mm thick, 15mmx15mm shim on the SoC. Before laying it on there I put half a pea size of Arctic silver ceramique cooling paste on it.

I then put about half a pea of cooling paste on the chassi of the phone.

I then put the board back on the phone. I noticed that when I had done that, there was a small gap on the left and right side of the board, as if the shim was too thick. I don't know if there were any gaps before I did this so I can't verify if it's supposed to be like that or if the shim is a bit too thick.

Here's a video of the gap.

If you're going to open the phone, check if there is a gap first, there might have been one before the mod, I do not know.

I continued and assembled the phone again. After I had put it back together I instantly noticed two differences as the phone booted. Before this mod, all the heat my phone was dissipating came from this area.

After this mod, all the heat has instead started to dissipate from here.

I started up antutu benchmark and ran a benchmark. I checked the temperature of the CPU and the temperature was 45c. This is great compared to my earlier temperature that would've been around 70c. As mention above, the heat seem to have shifted to the chassis and so makes a screen hot instead. This shouldn't be a problem however because the chassis stretches all around the phone and the heated spot in the top of the screen never gets really hot, it's merely a bit hotter than before, as compared to before the mod when the back of the phone used to get so hot I could barely touch it.

It should be worth mentioning that if you have a phone that runs very hot, you might want to be a bit careful with the screen as it could potentially cause problems in the future if your screen is very hot all the time. My screen hasn't got very hot, only hot enough to notice really so I'm not that worried.

So, all in all I am happy with the mod. It pulled my temps down from 60c to 35c in idle and works like a charm :good: ;)
[G3 General] nerdo:
Nicely done..... thanks for sharing the details with pics and video :good:
[G3 General] arebokert:
Update: I have noticed a considerable amount of heat on the top part of the screen. If you are worried about your screen taking damage from the heat I wouldn't recommend this mod. As I said in my earlier post, it doesn't bother me too much but I can see how someone else could be affected by it worse than me.
[G3 General] Racer-1:
That's not really a problem. My phone got hot at the same part of the screen without the mod.
[G3 General] fridaycider:
This is a very good mod with great tutorial. The only thing I might do is just use thermal pad or thinner kind of shim as i wouldn't want to put any stress on the board because of solder joints. It's just my theory and maybe not correct. I just dont like flexing the main board.

Didn't the.0.3mm shims fit better?
[G3 General] arebokert:
I thought the 0.3mm shim was a bit too small in thickness. I was afraid that if I chose the 0.3mm shim it wouldn't make proper contact with the chassis. I am not sure if the gaps I spoke of in the guide were there before I applied the shim so I can't really say if it was too thick or not. After I put the plastic covering on I didn't notice any difference in its positioning which leads me to believe the gaps could've been there from the start.

The mass of the shim sticking up above the rim of the SoC socket wasn't very big at all as you can see in the picture, with the 0.3mm shim I don't think it would've even been raised above the rim.

EDIT: I should've mentioned, I haven't noticed any issues in regards to fit at all after I assembled the phone again. My theory is that if the gaps weren't there from the beginning, the fit is much tighter between the SoC and the chassis now than it would've been if I used the 0.3mm shim. I will of course update if I encounter any issues in regards to this down the road but as of now it doesn't seem like I will.
[G3 General] liamR:
I used precision knife and metal ruler. You can order the thermal pad from Amazon France -

http://www.amazon.fr/ARCTIC-Thermal...1440594327&sr=8-2&keywords=arctic+thermal+pad
[G3 General] fridaycider:
Thank you for your informative reply. I might have a go at a shim once I order some and see how it goes. Just have a thermal pad in at the moment. I didn't cut it to the exact size as it should squash into the gap once put back together and seems to be ok.
[G3 General] Kigsuha:
Anyone here that tried both paste + copper shim and only thermal pad ? comparison of cooling performance ?
[G3 General] Kigsuha:
So I planned to do the mod with cooper shim and thermal paste, for the paste I plan to use arctic thermal paste but for the shim, didn't find any name , amazon shows a 30x for roughly 5$, is that one fine ? Are all copper shim the same quality ? Any copper shim to recommend ?

(Very sorry for the double post, forgot I had already a post).

Sorry
[G3 General] pajrul:
well, thanks to this forum and the generous posters who shared their knowledge, i took the plunge and did the thermal mod. I am not a diy kinda guy and believe i am the clumsiest person that ever lived. So you might expect how nervous i was. ( and in all nervousness i forgot to take before pictures). Items used was a 15mmx15mmx1mm copper shim arctic mx4 thermal compound. I followed the video to the letter, going over and over parts that are not clear. And i would say, as a respond to a previous poster that there is a gap after installation on mine too . Except my copper was twice as thick (1mm) but it still screwed on without resistance. Reinstallment was a breeze. All in all it took me 10 mins. And the handphone booted up sweetly. i have not tested the temperature. Everything went smoothly and i was beginning to be happy

Buuuuuuuuuuuuuuut as i cleared away things ... horrors!!!!! there is a leftover part left on the work area which i didnt notice before (definitely from the LG G3 coz i cleared up the work area before starting). Here it is next to my trusty screwdriver https://instagram.com/p/630GFHL0LO/

anybody knows where this part is? help! . I know it didnt breakoff from any phone part as it is made of rubber. : (
[G3 General] pajrul:

[G3 General] Pacote-san:
After a few days going crazy why the hell my gps was gone (tried stock roms, AOSP, going back to the stock kit kat rom and nothing) and i coulnt get gps lock

Decided to open up and take the cooper shim. Gps lock in less than 10 seconds

Perhaps it was some interference issue, already ordered the silicon thermal pad
[G3 General] Kigsuha:
Anyone using copper shim has this problem too?
[G3 General] Shadowjump:
Works perfectly good with a good quality thermal pad. My temps dropped from 64-65C when having the camera open, to 50C. Thanks for the tip.
[G3 General] arebokert:
I do not have this issue and I have a shim.
[G3 General] jamesmatt:
I know how that feels. My fingers burns.
[G3 General] :
I just used some thermal paste from work that we put on heat sinks for power supplies and my temps have dropped a lot. @ 10-15deg C when stressed.

I'm still surprised LG didn't have this included in their manufacturing process. I don't know if it was nefarious(the "manufacturers dont want to build things TOO good or it hurts future sales" conspiracy) or just ignorance but they definitely missed the heat issue during initial testing.

Props to the op for posting the mod. Thanks :good:
[G3 General] liamR:
I'm pretty sure that LG's engineers didn't miss such design benefit. I think some of us will face the consequences of this mod in the near future and it will probably not be so good. That being said I'm still keeping the mod ;)
[G3 General] Kigsuha:
Yeah keeping/doing the mod is the right thing to do.

If your g3 overheat and let it like this, its like having 2 hands but using only one.
[G3 General] :
Even if it overheats the LCD and damages it in time I'm cool with that. LCDs are easy to replace and much cheaper than a new motherboard.
[G3 General] Kigsuha:
And if you don't play lots of games or heavy tasks with the mod , it won't damage the phone at all and keeps it cooler right ?
[G3 General] liamR:
Maybe...
[G3 General] arebokert:
Only time will tell. It probably depends on how hot your phone usually runs without the mod.
[G3 General] ronzky321:
I believe the MAIN purpose of this mod is to

distribute

the heat coming from the processor. The OP just used thermal paste, so SOME of the heat goes to the chassis. Other people who used shims/pads may have caused all or most of the heat to go to the chassis, because these are more efficient in transferring the heat. Prolonged heating of the LCD this way may damage it. Just saying...
[G3 General] motoralbi:
Well,other phones with our SoC are built with thermal pads by default. Yes, 'cause of the QHD screen our 801 heats a little more than an 801 in a galaxy s5/xperia z3,but don't think it will cause many problems to the LCD,which already gets very hot during heavy usage.

[G3 General] pap96:
hey guys has anyone noticed what is engraved on the chip that you apply the thermal paste on?

i must be the ram module..it says "elpida fa164a2pm"

i dont believe its worth cooling it..but i tried and noticed my phone got a bit hotter and even froze on youtube videos :/

i have the d855 eu variant
[G3 General] jcfunk:
I just did this. Been running phone for hours.

Temp used to be 140F or higher. With lots of over heat shut downs. Now it's 96F with screen off, and highest I've seen so far 124F.

When I get on a computer, I will post picks of what I used.

This is the best 15 minute mod I've ever done.

I used Arctic Silver 5 High-Density Polysynthetic Silver Thermal Compound and 15mm x 15mm x 0.5mm Notebook Laptop GPU CPU Heatsink Copper Pad
[G3 General] heirei:
I believe that rubber piece is seated between the notification LED (on the upper corner of the board) and the frame of the phone.

---------- Post added at 04:26 PM ---------- Previous post was at 03:32 PM ----------

I just did this mod on my D850 using K5 Pro thermal paste (it's a thermal pad replacement paste...basically a really viscous thermal paste) and I'm not noticing much difference in the idle temps (still between 39-41C) but under heavy load, the CPU has been able to stay just under 75C. Previously, it would go up to 85C, even with the CTT mod installed. Overall, I think it's a great mod and it definitely works. I wonder if there's a "break-in" period for the thermal paste before it reaches its optimal performance. I also wonder if I applied too thick of a layer and if a thinner layer would help with lowering the temperatures even more, especially the idle temps. I'd love to see that go down to 30-35C (maybe too idealistic?).
[G3 General] NFleck:
Would this void the warranty if sent in for heat related issues to the display? And the video in the OP seems to put far too much paste i would think.
[G3 General] liamR:
As long as you remove any sign of the mod before sending it to warranty you shouldn't have any problem.
[G3 General] NFleck:
Arent there any stickers on a screw or something like that?
[G3 General] Racer-1:
No, there is no sealing or anything.
[G3 General] Kigsuha:
just wondering, on the stock lG G3 STOCK BATTERY

there is a "40°C /104°F" icon, does this mean the lg g3 STOCK BATTERY can't go above 40°C /104°F ?

mine usually runs between 35°C and sometimes 38°C, does this mean if i applied the mod, my battery would go over 40°C and stop working since the heat would spread through all the smartphone ??
[G3 General] djdeeles:
I used aluminium foil and thermal paste. Folded 3 times aluminium foil and used thermal paste on both sides of folded foil and applied.

Results never gets pass 60 degrees. Before it gets over 70 degrees.
[G3 General] motoralbi:
Well my battery under heavy use reaches more than 40°C,and i didn't do this MOD. So i don't think the battery will stop working if it reaches more than 40°C.

[AT&T LG G2] cliffm10:
I was wondering if anybody can speak from experience about how updating the LG G2 D800 to Cyanogenmod 12 might have on the camera? I've had pretty good experiences using Cyanogenmod on other devices. I just purchased the LG G2 mainly because I read that it had a pretty decent camera with image stabilization and it is economically priced. I'd be hesitant to move away from Stock KitKat if it negatively affects the camera. I've read that the G2 is full of bloatware (AT&T) and strange extras from LG. Of course I'd like a clean CyanogenMod 12 to get away from that if possible.

Any feedback appreciated.

[One (M7) Q&A, Help & Troubleshooting] Austinh1517:
Hello,

So I made a thread earlier about my Verizon HTC One M7 on 5.0.2 asking if I was able to root it.

Y'all basically said I need to use Sunshine S-Off to unlock my bootloader so I can root. So I downloaded the Sunshine-latest.apk file and it says I need to "Pre-root" before I can use it. I'm confused. :eek: The app that's going to root my phone needs root to work? That doesn't make sense. I now understand that S-off is needed for roms, but I don't want roms. I just want root apps. I'm still confused on why S-off is necessary for root, and apparently root is needed for Sunshine S-off.

Anyways, does anyone know how I can pre-root (Temp root?) my phone so I can use Sunshine? And what do I do after I get S-off to root my phone? Is there anyway I can root without S-off? I just want root access no roms.

Thanks for all those willing to help. Sorry I sound like such a noob (I am)
[One (M7) Q&A, Help & Troubleshooting] alray:
Yes I remember but don't understand why you created a new thread again for the same issue... Your previous thread is only 3 days old.

http://xdaforums.com/htc-one/help/to-root-htc-one-m7-t3127604

Right because Verizon asked HTC to block their phones from being unlocked the normal way using htcdev.com website so they can have more control over their customers. With S-OFF you or sunshine can directly write to the PG1FS partition to unlock the bootloader without the need to use the unlock code generated by htcdev.com

Sunshine need at least temp root to work. Achieve temp root, use sunshine to s-off and unlock, flash a custom recovery and then using your recovery you can root for good (permanent root).

Not really but that doesn't matter for now, you can read about what s-off really do later if you are interested. Flashing roms doesn't require s-off, its only requires and unlocked bootloader but yes since your phone is Verizon you need s-off if you want to flash a rom because its the only way to unlock the bootloader. On other variant of the M7, you can unlock the bootloader from htcdev.com so s-off is not needed to flash roms. I know its confusing...

Because you need at least an unlocked bootloader to permanently root your phone, bootloader unlock is blocked by Verizon so S-OFF will unlock the bootloader

temp root, not perm root.

http://xdaforums.com/showpost.php?p=61174630&postcount=4

Read this post again (second sentence)

Flash a custom recovery (TWRP) for Verizon HTC One and use it to perm root your phone.

Afaik, no, not on the new firmware.
