Needed an inexpensive spare phone. Picked up a Nexus 5x 16GB for less than USD50, with problems (Unable to turn on, only red LED when trying to charge) so starting a project to revive it.

Stumbled across this thread.

Bit the bullet and bought the oudini UNLOCKED H791 32GB Mainboard with the 4GB RAM and a Da Da Xiong 3400mAh Battery to go with it.

Planning to do the copper heatsink mod too.

Was thinking of expanding on the idea of the copper heatsink mod with this Experimental "home-made" modding for heat dissipation mod. Aluminum foil was used along with liquid metal thermal compound in that thread. Not a good idea as liquid metal with aluminum is a recipe for disaster. I was thinking of using copper foil instead. Haven't decided on whether to use thermal paste or liquid metal. Also thinking of creating a bigger surface footprint for the "heat dissipation pipe" like the attached picture.

Your thoughts? :confused:

Will update once all parts arrive and I begin assembling. :fingers-crossed:

Good luck with that. Sounds like fun.

With that mainboard, is there any guarantee it won't start bootlooping a few months down the road?
[Nexus 5X General] flatpedals:
Good to see somebody else dumping money into such a hobby :)

Aside from my daily driver 5X, I have another one now at the shop for a reballing job - kind of a long story, outcome still unknown :)

I don't think that whole 'heat pipe' situation is needed, you are going to be fine just with the copper pad.

I've been running it for a few days now and honestly it's more than enough. You won't get anymore performance out of this chip unless you go sub zero cooling or something. :)

Seriously, having it run at 30 to 40°C on daily normal usage and 40 to 50 in games or other intensive tasks is just fine.

Thermal throttling is also kept to a minimum, especially with the non-stock thermal configs.

That battery capacity is jank, you can't physically fit that much juice into that space.

The best battery you can get your hands on is a LG *allegedly* original unit from Amazon sold directly by LG. Other than that, you are always going to end up with some knock off that gives you, at best, the same battery life as a 3 year old original one.

Good luck with all this then.

But you'll probably ditch it all in a year's time for a Pixel, when you'll want that fresh Android. That's going to be my story, anyway. :D
[Nexus 5X General] LeonF:
I guess there are no guarantees... My understanding is, this bootloop is caused by hardware problem with solder connections between the board, RAM and CPU. The RAM is packed with the CPU together on the top.

This main board has had a new RAM/CPU soldered on. So unless it was a shoddy job, it should all work. Now, under heavy load, heat builds, and when it gets too hot, there is a possibility of the solder connections giving problems again. Which is why I thought of doing the copper heatsink mods to reduce the chances of it happening. Also, with the 4GB of RAM, I am hoping it will have less stress on both CPU and RAM, which in turn will generate less heat, thus reducing the chances of the problems with the solder connections.

All this is just theoretical. I guess I have to build it and see how it goes. :fingers-crossed:
[Nexus 5X General] LeonF:
I don’t really game on phones but where I live, temperatures and humidity are quite high. Not looking for crazy performance, just hoping the phone stays cool and will last a while. ;)

As for that battery, we’ll see. No harm trying after all. A guy on reddit bought one and said it does last longer than the original. If it sucks, I’ll just revert back to the original one. :D

This is just a small hobby/project, who knows how long I’ll use it. I actually already have a Pixel 2 XL. As I’ve mentioned, this is just a spare. :cowboy:
[Nexus 5X General] paradoxiumwind:
I also bought one of the 4GB boards (two actually) and replaced a dead N5X from ebay with the upgraded one. Works flawlessly, will post screenshots of the system info of 4GB RAM soon when I have my phone sorted.

I'm curious about that battery though - is it legit 3400MaH?

This is the 4GB board I bought, same as you. My first two didn't make it past chinese customs but he sent another two and they made it fine. https://www.aliexpress.com/item/oud...for-LG-H791-32GB-Motherboard/32846103543.html
[Nexus 5X General] zurik:
At the moment, no one reported bootloops on Nexus 5X with 4GB Ram. We will see in the future.
[Nexus 5X General] paradoxiumwind:
4GB board installed, just installing apps and setting it up etc. Feels snappier anyway. When installing ElementalX kernel, I set the read-ahead buffer from 512kb to 1024kb to adjust for the increased RAM.
[Nexus 5X General] zurik:
Soon I will order one Motherboard. If my 5X will have bootloop again.
[Nexus 5X General] LeonF:
No idea but on the sellers ad, they say they use a EBC-A10H machine to test their batteries for the desired result. Also, there are a couple of brands besides the Da Da Xiong one that I bought. There's HSABAT, LOSONCOER and IBITION.

On reddit k3v1ng1994 says ;-

I guess there is an issue with calibration but I think should be an easy fix with a flash of stock images (or factory wipe) and batterystats.bin will be removed in /data/system... Should be calibrated after that. Not sure which brand he bought though. Who knows. Will try and see how it goes.
[Nexus 5X General] LeonF:
Got a notification, my items have been shipped!

Main board should arrive by the 2018-03-18 but the battery says 2018-04-08 :eek:. I've ordered stuff from China recently and they usually arrive before their estimates. Hopefully they get shipped out of the country before their Chinese New Year holidays. Then it's up to my country to deliver the goods.

Took apart the phone today and tried the "heating" method fix but it didn't work. I got as far as getting "Google" to appear on the screen then it gets stuck there.

Anyway, looking at the heatsink/"heat pipe" mods, I'll probably stick to thermal paste instead of liquid metal. Liquid metal is corrosive. Even with copper the metal ions will migrate into the copper metal, gradually creating a copper-gallium alloy that is grey-silverish in color. Which is why people think it's drying up. It's actually the copper absorbing the liquid metal.

Looking at what PC CPU heatsink are like these days, the contact point is usually copper, followed by aluminum fins for faster heat dissipation. Why not just follow that recipe. :silly:

So, looks like the copper foil I ordered won't be of any use now :laugh:.
[Nexus 5X General] paradoxiumwind:
Really don't think a heatsink mod is needed, in my old phone I used a 0.1mm(or 0.2mm I forgot) copper shim over where the CPU is, stuck it on with thermal paste, didn't make much difference in cpu temp.
[Nexus 5X General] flatpedals:
A .1 or .2 mm shim won't indeed change anything, it's way too thin for the chip to be in contact with the chassis. Especially if you don't remove the factory yellow pad and the thin foil from the chip shield.

With a .8 or .9 mm copper pad (can't tell for sure, I sanded down a 1mm pad) I can guarantee that you'll notice the temp difference, the throttling is almost gone.

It also depends on what thermal paste you use and how much of it.

Also to everybody wondering why the bootloop issue occures, here's a few things:

The 808 and 810 were the first x64 chips Qualcomm came up with as a response to Apple's. So you can imagine they aren't exactly well thought out, especially in the long run. You can do a bit of research to see how they just janked together some ARM cortexes, slammed a GPU in there and called it a day. Samsung even ditched the 810 from the S6 and used in-house silicon - I think we can safely assume Samsung knows its hw game.

The stock thermal config and kernel are absolute garbage and don't help at all with the thermal throttling that keeps the little cluster pinned at 1440Mhz and the big one off, anytime the package is above 46°C - that's most of the time. Now you tell me how easy that is on the hw.

These design flaws coupled with possibly bad soldering led to our problems. Even though it's hard to imagine that so many boards made it out of the production line with bad soldering since that's a mostly automated and very tidy job, leaving little to mistake.
[Nexus 5X General] CLPose:
I don't want to go OT, but understanding some things may help "solve" the heat / bootloop problem in non-bootlooping N5X. In stock kernel, through ExKernelManager, I've seen CPU at 96º C when taking photos with HDR+ :eek: With Jolla kernel and the big off, CPU hardly reaches 60º C. If soldering is not "the problem", an "accurate" kernel configuration will be enough to avoid the bootloop? :confused: Sorry if I misunderstood your explanation or if I ask something stupid. I know nothing about this, but I would love to learn something. ;) Thanks!
[Nexus 5X General] flatpedals:
All I'm saying is pure speculation, the web is filled with people talking bs about 808 and 810.

Also, Qualcomm, LG or Google never settled this with actual honest facts.

Another fact is that some Huawei made Nexus 6P devices bootlooped as well, so you can see how one could easily think that the root problem is the architecture itself of that generation of SoCs.

On the other hand, I can make an 'educated guess' about how a cooler running package prolongs its life and puts less stress on the 'allegedly' weak soldering.

So I think it's safe to assume that running a custom kernel and thermal config, along with other tweaks like the heatsink, will dramatically increase the life of your 5X.

Hello friends first forgive the translator's mistakes. I already knew this topic before but did not know that the motherboard had already been sold already modified.

My thanks to @LeonF for providing the link of the sale of the motherboard with 4GB of RAM.

I already have a functional 5x nexus, but I bought another today with the burned motherboard per US $40.00. Then I bought the motherboard per US $132.05 5% off.

Unfortunately I live in Brazil, the customs (IRS) here are horrible, it will certainly take up to 70 days for me to receive the product, as soon as arrive i come to post my opinion here... on a battery 3400mAh do not think it's good.
[Nexus 5X General] paradoxiumwind:
I have noticed with my 4gig ram board, my battery usage is really good. same battery. ordered two of those 3400mah ones though, but somehow more ram = better battery time
[Nexus 5X General] LeonF:
Copper shims arrived today. They're 15 x 15 x 0.8 mm. Took the phone apart, did a mock of the copper shim then cleaned off the yellow thermal pad...

[Nexus 5X General] LeonF:
So @Mortihead found a service that will replace your emmc chip to 32GB, 64GB or 128GB and mentioned I should try.

I got in touch with them and found out (as best as I can understand the WeChat translator) that the 128GB chips have been out of stock but they still have the 64GB ones and it will cost RMB280 to do it.

I found this chart from @ikfe from this thread of the part numbers...

Searched for the 128GB chips and found this for USD$35. I can go as far as fitting the new 128GB chip but I have no idea how to proceed after that. Reading the thread about [MENTION=7245337]KApetz2[/MENTION] and how he fitted a 64GB eMMC to his Nexus 5 you have to fix the partition tables to support the larger capacity storage or it wouldn’t recognize the upgrade. If someone can point me in the right direction, I might try it out. :D
[Nexus 5X General] Komodoketavaran:
Hmm, there have to be different RAM chips out there that are compatible... In this video there are 3,9GB available. The most of the other phones with the RAM Upgrade I have seen there is 3,6GB available.

The oudini Mainboard arrived today. That was quick. Ordered on the 7th, arrived on the 13th using AliExpress Premium Shipping.

Hooked it up to test it but it looks like my battery is dead as well :(. Will pick up an OEM battery whist I wait for the 3400mAh one to arrive.

Edit: Picked up a battery and booted it up. Came with Oreo 8.0.0 installed already.
[Nexus 5X General] LeonF:
Copper foil came today so I did the copper heatsink mod.

Cut out and lined the screen side with copper foil.

Then cut out the mesh thingy.

I tried using thermal paste but mine was a bit old so it was a bit too pasty for my liking...

Ended up using Conductonaut Liquid Metal instead since I used all copper. We'll see how it holds up. :D

Still waiting on the 3400mAh battery to arrive...
[Nexus 5X General] thesebastian:
Thank you for this topic.

I have 2 5X at home.

1) One is my old 5X with a totally baked motherboard, (and warranty was denied by LG Spain before i started baking, because, they decided to flip the coin, say that the bootloop issue was a liquid leak or something, and tried to charge me 330€ for repair). --> I've just bought a modded 4GB motherboard for this nexus.

2) The second one is an Amazon Refurbished (with Warranty I think 2 years) 5X that my gf is using. This one was cheap, like 190€ 7 months ago --> If Nexus 1 is fixed, I'll probably do the same with this one, because currently the Nexus 5X is very low on free ram and sutters all the time, I disabled assistant, google feed, OK Google always listening, etc. But free RAM is still below 700 and in my experience, when free ram is below 1GB, the phone becomes very slow. (Even in my Pixel 2, after 5 days of standby and free ram is oscillating between 1.2 and 1.4GB, the performance is a bit decreased compared to when the free ram is 1.4-2.0).
[Nexus 5X General] octavioromo:
I have some feedback on doing the copper shim mod. It appears as though there is some GPS interference when using any metal shim in place of the thermal pad. I tested this with a .8mm copper shim and it was slightly too thick that created a slight bump but everything seemed to connect to the antennas on the back plate. Used the phone and had terrible GPS. Tried just testing with just a thinner square from a tin can that had no clearance issues and i also lost GPS signal. Went back to a Arctic thermal pad, mine was .5mm but its a bit on the thin side and was barely making contact, used a bit of thermal paste. Not the ideal solution but is better than what i had before. Let me know if you have any different experience with your copper shim mod.

I used GPS Toolbox to test satellite connections. with the either the copper of tin shim i would get only 2-3 indoors bu the window. After removing the shim with nothing in place and with the thermal pad i would get 7-9 in the same location and at much faster speeds.

Let me know if you have any questions
[Nexus 5X General] flatpedals:
[MENTION=1838842]octavioromo[/MENTION]

I have the copper pad in there and I can't confirm your trouble with the GPS.

All I can think of is your back cover that has all the antennas on. Make sure they are in contact with the pins on the board. Maybe the pad changes the height the board is sitting at and causes some contacts not to touch properly.

I can't see a reason for the pad to be interfering with anything. The whole chassis is made of some aluminium, so you could say that interferes too, but I don't think it's a problem at all.

Oh and please don't quote such long posts like that, it clutters everything up. XDA Labs takes forever to load such a long post that has images too.
[Nexus 5X General] octavioromo:
I did think it was a clearance issue,I raised the pins slightly to ensure connection, and when using the tin shim that doesn't make full contact I also had issues. Very odd. I'll try and get slightly thinner copper shims and give it another go. Can someone tell me what points are for the GPS?
[Nexus 5X General] flatpedals:
I guess we don't know for sure, the labels are cryptic.

All I know is the one around the camera lens is the NFC antenna.

So you're left with four other contact points.
[Nexus 5X General] LeonF:
I too have no issues with GPS signals.
[Nexus 5X General] Flyview:
This is cool! I'm trying to sell my Nexus 5x but I'd be up for upgrading the motherboard with the 4GB of RAM just for fun, if it was a bit cheaper...

Yes that's normal. He shipped my board when the clock was ticking at <24h. Message him as he responds promptly. I had to poke him twice. My board is on its way :laugh:
[Nexus 5X General] thesebastian:
Is your shipment with DHL by any chance ? My OUDINI was shipped at the last hour of the 13th day. However, the provided DHL tracking number still doesn't work. (I'll wait 2-3 days but probably the item hasn't still shipped).

I bought two of the 4GB RAM boards, using one as my main phone and stuck the other one up on ebay; https://www.ebay.co.uk/itm/323095744155

Hope it's ok to post the link.

Anyway what do you think of the price for that? is it too high?

I haven't notice much difference with my N5X to be perfectly honest - although when I check the RAM usage sometimes it's about 2GB+, so it must be helping a bit.
[Nexus 5X General] vewa52:
I suspect so too. It still hasn't shown up on the tracking site. Guess all orders have been delayed because of Chinese New Year.
[Nexus 5X General] paradoxiumwind:
They were pretty slow shipping mine, infact the first shipment seemed to be stopped by chinese customs so he had to re-ship me my two boards.

Out of curiosity, do you have custom ROMs installed? Does unlocking the bootloader stick across reboots? I am seeing some buyers of the 4 GB motherboards say that bootloader unlock is not persistant across reboots. This is keeping me worried.

Yeah the boot-loader was locked when I got it on both, in Chinese so Chinese boards I guess? I unlocked them and everything was fine / in English then, have rooted/installed custom ROM on it and the unlocking has persisted fine, just like a standard board.

Is it possible just to replace the original Samsung chip (K3QF3F30BM-QGCF 2 GB LPDDR3 RAM) with a compatible chip?

Compatible chips suggested by some members that have their phone upgraded:

- H9CKNNNCPTMT LRNUH from Cathair290 4GB RAM upgraded of my Nexus 5X. Probably the same chip on this thread's oudini LG Nexus 5X mainboard?

- K3QF4F40BM-FGCF

These chips can be found on aliexpress. I was thinking of buying and replacing the board like LeonF suggested, but I think it would be cheaper to buy the chip only, however it will require some handy job to replace the chip. Has anyone tried this method? and please advise if it's possible to do so. Thank you :o

Can you tell me if it really works like a 3400mAh battery? Thanks
[Nexus 5X General] LeonF:
I don't know. Until today, battery hasn't arrived yet...
[Nexus 5X General] Cathair2906:
Very interesting post.

To be honest, someone has mentioned the that 3rd party 3400mah battery indicator stuck on 50% which is the fault from the battery itself instead of your 5x hardware, i have experienced this issue before. Moreover, pls look at the comment below of the aliexpress link, someone has feedback that the high capacity is fake.

And also, about the issue of bootloader unlock is not persistent across reboots, i have done a deep research on this issue as well. The only answer i've been told from a repair shop, they said this issue is caused by using a second hand S808 SoC instead of using the brand new S808 SoC.

Hi,

I setup the 4gb ram on my nexus 5X.

And I see the difference between the old configuration.

The nexus 5x is very fast. :cool:

Let's see the attachement.

But be careful when you wanna change the mainboard. There's a really small black rubber housing piece that you need to transfer from the old frame to the new one.

This black rubber is on the proximity sensor. :mad:

If you forget it, the phone stay on black screen during call, after you can't turn screen on. You must wait the conversation muste be ended by the other caller. :eek:
