very nice work!

ive got a friend who can cut some copper plating.

So when your done and it works i would love some dimensions.
[Nexus 9 General] Philaphlous:
I took down some of the mod guide since it wasn't really a huge benefit. I'll be picking up some copper tomorrow and I'll be getting some glue to go with it. I'm on a big time budget do it might not be thermal glue but it'll still do the job...
[Nexus 9 General] toopy:
Will one of those flat ram sinks fit in there?
[Nexus 9 General] Philaphlous:
No. There is barely enough clearance for anything. At best you can manage maybe a 2mm heatsink tops. I'm using a solid copper sheet that's 0.025 thick.. Which is about 8x thicker than the normal shield they come with... It's literally like a thick piece of aluminum foil...

I should have new pictures and results up tomorrow. I just got the solid sheet of copper today
[Nexus 9 General] toopy:
easy way to make thermal glue is to mix a solution of 1/2 araldite (epoxy) and 1/2 of your choice of thermal paste.

I use generally use Arctic silver 5 as that's what I normally have on hand.
[Nexus 9 General] Migamix:
and how is the WiFi radio reception after the copper alterations . there are calculations involved in having antenna design modifications that need to be considered.
[Nexus 9 General] Philaphlous:
Well the strange thing is the mod works great... However, it doesn't really help throttling... So something else has to be throttling down the chip...

Quite disappointing.

The actual chip will throttle at 72c ... However at 2.5ghz it's maxing around 68c on a stress test...

Another strange thing is when the gpu is overclocked to 950mhz the temps go through the roof on some stress tests. I've seen temps upto 87c when stressing the gpu and that's after the mod. Overclocking just 100mhz creates a huge temp difference for the gpu...
[Nexus 9 General] Philaphlous:
OK a revisit from the past... The mod helped some but it is still lacking. I ended up breaking down and purchasing 2mm thick thermal pads last night. This is vitally important for this mod. I will have a new guide up in a week or 2 once I get the pads and install them. I've realized the thermal transfer is terrible with the stock 0.5-1mm thermal pad... Hopefully this will finally resolve the heat issues.
[Nexus 9 General] berendspruijt:
nice make lots of pictures ^^
[Nexus 9 General] Philaphlous:
Here is the heatsink I will be using. It is 0.025" thick copper. It's about 50x thicker than the copper foil previously used.

I should have the thermal pad here by Friday I think. Stay tuned.
[Nexus 9 General] tomkins0752:
I came across this thread and decided I would try this as well.

If I play a good 15-20 minutes of Kingdom Rush, the side would get really hot.

So I ordered a couple 1.2mm bronze heat pads from Amazon and just put them in.

The back cover just barely snapped back on, but it doesn't bulge or anything.

Now to go test it out.
[Nexus 9 General] fallen2004:
I am very interested in this thread. What is the point of powerful cpus if they just get throttled.

NAND reflush?

Excellent stuff you wrote here - thank you.

Any hints on how to resurrect dead B15Q that has damaged/erased NAND or a Preloader?

In this link http: // forum . xda-developers . com/ showthread.php?t=1943442 a forum member

claims that mt65xx have META mode even if they appear dead - like mine B15Q is right now - and could be

revived with SPFT and proper W7 drivers.

Does under those circumstances PRELOADER might be reflashed?

I read just afterwards that one should not do fully ticked Memory Test as it silently reformats NAND.

I guess this is what happened in my case.

Also, a reason to do this test was that reflashing the phone with 1.010 BOOTIMG, ANDROID and RECOVERY, having it back for a brief moment and then upgrading it via OTA to 1.019 that had bricked it in a reboot loop.

Any clue would be welcome.
[Android Q&A, Help & Troubleshooting] harddisk_wp:
Bigal1337's image should also contain a preloader, but I guess in your total-dead state it'd be better to send in the device for warranty... after all no one can prove what exactly zeroed out your NAND.
[Android Q&A, Help & Troubleshooting] uhuru-meditation:
It is all OK now and B15Q is alive and works well, as it did before the "big brick" Christmas blackout.

The main thing is that thanks to MTK low-level USB communication on chipset as is in B15Q makes it "unbrickable", really.

The other thing is my bad clicking around and "checking memory" while not really knowing what I am doing.

As well as Windows x64 drivers, admin rights and all the other voodoo lurking in there.

What troubles me more is how come that CAT ppl. allowed "bricking" device upon system update, while root or no root shouldn't really matter there?

They sell it unlocked, so they should sell it, as well, with an easy option to root it. As Nexus One from Google had this "build-in" option.

I still hope that future updates will not have the same behaviour and also that there will be an alternate option for some other flavour of Android.
[Android Q&A, Help & Troubleshooting] harddisk_wp:
I think I have found something... this chinese rooter apparently messed with internal symlinks, and the firmware update broke as it assumed "stock" contents...

Another reason not to trust rooters where one can't even read the description because its chinese...
[Android Q&A, Help & Troubleshooting] uhuru-meditation:
I agree there. I gave up on rooting B15Q.

On the side note: lately I had 2 spontaneous reboots after this reflash and resurrect.

It happened after I used "official" messaging app more precisely after I send a message and close the app..

.

Did anyone noticed this? - it is 1022 I have up and running.

Other than that it works fine.
[Android Q&A, Help & Troubleshooting] EppoEppo:
Hello,

I tried your workaround but haven't succeeded yet. And yes my phone also is bricked, unfortunately.

My phone halts where you have to choose a language after a factory reset. At that moment I get some messages that some services had stopped. Like Google keyboard, Youtube and some more. I can click OK but this doesn't get me passed these messages and they reappear. I only can switch off the phone.

I tried your workaround on a x64 machine (and got the PMT message) because that's what I have. I am preparing a x86 machine which has XP on it but on launching SP Flash Tools I get the message the configuration of the computer is not correct. Will W7 32-bits do the trick?

Also two more questions.

The downloaded images are : boot.img, recovery.img, system.img and uboot.img.

In your explanation you're mentioning : BOOTIMG, RECOVERY, ANDROID or USRDATA.

I presume that in SP Flash Tool I have to use the system.img in the row ANDROID?

Or should it be in the row USRDATA?

You don't use uboot.img. What's the reason for that? For what purpose is this image?

Update 19 april 2015.

I managed bringing back my phone to life. I did another attempt by rebooting my 64-bits computer (as you wrote in the beginning) because at that moment I didn't had a 32-bits machine. It worked wonderwell. So, I'm using my phone again. Like uhuru-meditation I give up rooting for the moment. Nevertheless Android 4.4.2 I still like this phone. Hope it won't let me down after this major reset. Keep fingers crossed.

harddisk_wp many thanks for your hard working in making this workaround. It sure has cost you more then an hour's work.

I hope you read my questions and can or will answer them.

CAT B15 help

Hi guys, i'm sorry i have to ask this in this forum but i've been asking for a couple of months now, and got no answer. I have a CAT B15 (not the B15Q). It is single sim version (IMEI write on the back) and i managed to do plenty of things in it. I swapped memory and worked fine, and even i installed a Dual Sim android rom and i managed to use the secondary Sim bay in it (that was tapped with a plastic fake sim) and used the phone with 2 sims for like 2 weeks. Then i started to play with deodex and build.prop and softbricked the phone, but it was piece of cake since it is easy to unbrick. The problem was that i wrongly flashed the phone with scatter file, and flashed all partitions in it, EBR1, MBR, UBOOT, etc, etc. The result was a non-working dual SIM phone. Everything works, but the SIMS, it does not detect any SIMs in it, in any of the SIM bays, and the IMEIs are wrong numbered. I did no buckup of the phone so i'm pretty screwed. I've been asking for someone to upload the EMEA_SS or US_SS ROM for the CAT B15, but nobody responded. I thaught maybe the CAT B15Q has a similar software/bands flashing partitions, but that i leave to you for answer. Anyway, if any of you has the possibility of taking the images of a single sim CAT B15 it would save me this awesome phone for me. I'm also willing to give a 20GB account of ownCloud server for 1-year free of charge if storage space is needed, no problem. This are the links i've been searching and asking.

I have the same questions as a previous user, but I cannot find any answer to it:

"Also two more questions.

Could you please help with these? Should I use uboot.img as well? And does system.img go to the Android row?

I added this 3d question later: is it safe to flash SS phone with the DS file?

"PMT changed for the ROM" and SP Flash Tool version

Hello,

I'd like to say big thanks and report that my B15Q was saved thanks to this thread, after a failed upgrade to the 1.016.00 firmware (due to the Chinese root app).

Moreover, I would like to point out that the procedure worked only with the v5.1352.01 version of SP Flash Tool. All other versions I've tried bailed out with the "PMT changed for the ROM; it must be downloaded" message. Unfortunately, the thread which is listed in the instructions refers to a version of SP Flash Tool more recent than v5.1352.01. A link to the said version can be found in this post: http://xdaforums.com/showpost.php?p=58810386&postcount=4

CAT B15Q - My Rear Camera doesn't work anymore

Good evening everyone.

After a bad update, my rear camera on CAT B15Q doesn't work anymore. I read all the posts here and I'm using Windows Vista Home Premium 32 bits. I downloaded all the necessary files and when I open the SP Flash Tool, I think it didn't recognize my smartphone and when I try to download any file to the phone the status bar on SPFT still stopped, like if anything is going on. I buy this B15Q on Paraguay. Could this fact be my problem? Anyone could help me, please???
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] kreemerz:
I am seriously considering ditching sprint in my area. Their network (Sacramento) has been the worse I've ever used.

I've heard about TMobile taking care of your ETF if you switch to them by offering customers what amounts to a credit card that you can use.

Has anyone done this?
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] puhiniho:
I've moved from Sprint to T-Mobile about two months ago. I really wanted to stay with sprint but there mobile service sucked... As I see your experiencing the same thing. I've heard T-Mobile service can be spotty in places but in Seattle and Honolulu (where I'm usually at), it's really good.

The only impact negative impacts are the cost of the phone. You just plain have to pay the $500 - $900 uncontracted phone. I'm not use to that huge amount lingering over me.

And I could be the only one, be I found Sprint customer service significantly better than t-mobile.

Anyway, if you can muster the cost of the phone, I don't think you'll regret the way better data /phone service. I did the 5-day try the service out from t-mobile initially. You'll get an iPhone 5s and try it in your area. Good luck!

EDIT: did get the ETF reimbursement, and you can apply it towards your bill /phone, that's what I did. Lastly, don't expect you'll use the same data amount between Sprint and T-Mobile. The data service is much better and I found out my wife and I use about 2x to 3x. So go unlimited if you can.
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] kreemerz:
Very good point regarding the use of the data once you actually get better service, I'm certain that it will increase. So, you're right, I may have to go with unlimited. Yeah, the coverage map for sprint is much worse than TMobile's. In fact TMobile's 3G is faster than Sprints 4LTE.
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] mgbotoe:
Tmobiel is going to have a server where you can stash your unused data if you are paying 30+ on your data (not counting unlimited) you can make use of that if you do not want unlimited as well.
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] ajr0312:
I also just ditched Sprint, data speed is faster and more reliable for me.

I just made the switch (in Mass.) after 10+ years with Sprint. Just got sick of their lousy LTE, and also wanted better international options. It's only been a few weeks, but I haven't been hit with the Sprint ETF yet. Anyone know how long it usually takes?
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] kg6bki:
I left Sprint and did the ETF for the $350 from Tmobile. I was sick of hearing from Sprint..."We are in the process of working on our Towers today thats why your LTE is not there" and that was at 3am in the morning...ummm.ok..

Ever since I have left LTE has been lightning Fast...I even saw I was on AT&T this last week when I was in the Central Valley and not in T-mobile Coverage...I was able to make and Receive calls. The LTE on T-mobile as far as I'm concerned blows Sprint out of the water...I was tired of the False Promises and the 7+ years of service from Sprint to be treated like crap.

The Downfall as others have said T-mobile phones are not cheap but as I don't have a house phone I am connected all the time with my cell phone.

I have a friend in Carmichael...Not far from you and he Switched to T-mobile and has been very very happy...

OP...make the switch and you will be very happy..

I hope this helps you...

[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] javisuhfiks:
Lol, exact same story for me. I was tired of their "promises to upgrade", it never happened. I left Sprint and never looked back. We had to use our credit card to pay Sprints ETF because they wanted full payment when we ended. It took us about 1 1/2 month to get our rebate card, but this was when T-Mobile started this deal so it might be quicker now. I have the 3GB of LTE data and never go over it since most of the place I am at have WiFi. And now with there rollover data plan, I am set! I live in Los Angeles county but I have had great service and speed from San Diego to Santa Cruz.
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] ummduh:
Just an FYI, sprint will let you out of the contract if you roam too much.

Right before we switched away from Sprint, we drove across the country and roamed practically the entire trip. The next month we called up and they offered to cancel our contract if we sent the phones back. Done and done.

The only real problem with t-mobile reimbursement system is it can 1-2 months for them to reimburse you. They did 2 of my 3 lines in just over a month, and it took almost 2 more months for the 3rd cuz they kept denying it despite it being legitimate.
[Nexus 4 Q&A, Help & Troubleshooting] eighteesix:
Hey guys. Been using this nexus 4 for ages. I've lived in Minneapolis and San Diego and encountered this issue in both cities.

Every few months, my texting app will tell me it cannot receive MMS messages. So I restart my phone, call at&t, etc do all the necessary steps and it eventually just goes away on its own. The issue is that even when the phone says 'cannot receive', I do receive some MMS messages but some I just dont. Usually it seems to be group chat related but can confirm sometimes i do not receive photos. Today i got the error again using a group chat and I just received a picture from a different friend (who is on AT&T like me). Are there issues between carriers with group chat or something?

I'm coming from years of android phones and have always purchased wireless Qi adapters for them. After experimenting with several different brands of receivers over the years, I became a believer in the Nillkin brand. They cost a little bit more but they are way better built. I have always bought this receiver and have never had a single issue with mine or my wife's galaxy notes. I recently picked up a note 4 and after using it for a few days, I realized why I stay with the note brand. Absolutely amazing phone. Naturally I waited till Nillkin made an adapter for my phone and picked one up.

I placed it on charge the first night and when I picked it up in the morning, I nearly dropped it due it being so hot to the touch. That has never happened in any of my phones. Obviously something is not right with this thing.

Here's the weird thing....

I'm running "SmoothKat" rom but have a stock rooted back up. Oddly enough, when I restored to stock rooted and placed it on charge, It would still get quite warm but nothing like it was on the custom rom. I also tried turning off Fast charge option but no dice. Anyone have any advice? Is anyone else having an issue with the wireless charging making the phone hot?

BTW I'm using the TYLT Vu charger.

Thanks in advance...
[Galaxy Note 4 Accessories] rcobourn:
Same charger here, using the OEM charging back. No heat issue.
[Galaxy Note 4 Accessories] docdrey:
Weird... It has to be this Nillkin receiver. I just searched around and noticed the Nillkin receiver has a significantly larger output of 850Ma. Most other receivers are 600-750 max. Could that be the issue?
[Galaxy Note 4 Accessories] rcobourn:
I have a couple of receiver cards too, no heat issue with them but could not get tap to pay to work.
[Galaxy Note 4 Accessories] stureiney:
Hmmm that's never happened to me, and I have the same Nilkin charger. Maybe something with your phone?

Was the charger equally as hot?
[Galaxy Note 4 Accessories] docdrey:
Very strange. It seems the issue has worked itself out. I woke up yesterday and the note was slightly warm to the touch. This morning, completely normal temperature.... Weirdest thing... its like it learned what was going on in the past few days and fixed itself.... Mind blown.

Thanks for the help!
[Galaxy Note 4 Accessories] buddhafool:
I had the same thing happen. I was using the OEM back with my TYLT, Airdock and Qi infinity chargers and it was running cool. The phone was too thick for my case so I switched to a Enpower transmitter with the original back. It was much slimmer but got WAY too hot. (I only tried it on my TYLT and decided not to F with it anymore.)
[Galaxy Note 4 Accessories] docdrey:
That's really weird. It may be something with our phones? I don't like the bulkiness of the oem cover so I was determined to figure out what the heck was going on. Shame I wasn't able to get to the bottom of this. Ill keep this thread updated as the days go by. I'm sure we aren't the only ones that had this issue.
[Galaxy Note 4 Accessories] buddhafool:
Maybe they use the extra thicknesses for heat dissemination. It has a metal plate near the bottom on the inside, maybe that acts like a heat sink. I am sure their engineers did not take the decision to increase the thickness lightly, there must be a good reason...

And yes they should have baked it in by default. A flagship phone needs this built in, they were just greedy for accessory sales I guess.
[Galaxy Note 4 Accessories] stureiney:
Well, I'm glad the problem solved itself for you, OP. I don't know why that would have ever been an issue, but hey, if it ain't broke, don't fix it.

My nexus 7 gets hot when charged using Nokia wireless charger. It stays hot even after charging is done. As if it won't stop charging so the energy needs to be dissipated somehow how so lt just generates heat.

I would NEVER use wireless charger on my note 4 because heat kills battery life.
[Galaxy Note 4 Accessories] psycovirus:
I use a cheap ebay charger and wireless receiver that fits into the normal backcover...

It warms up while charging but nothing too hot. Just like charging normally by cable... Ofcourse, the cheap wireless receiver only gets 600ma max from the wireless charger.
[Galaxy Note 4 Accessories] zurkx:
thats just silly. the note 4 stops charging and cuts off the qi charger when charging is done. you can see the wireless symbol disconnect.
[Galaxy Note 4 Accessories] THS1989:
Then the fault is with the Nexus 7 ? Sometimes i pick it up from the Nokia charger hours after it is done charging at it is still very warm, even almost hot.

Tbh I wouldn't be surprised. The nexus 7 I have has lots of issues like random reboots, touch screen issues. Many people have these problems. ASUS really screwed up the 2013 nexus 7.
