How do you get to this? Sorry I am a noob when it comes to this stuff. I am not sure if it did come with the new chip I bought this phone used.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] aybarrap1:
It is under settings. Follow this: Settings/More settings(under Wireless and network)/ Mobile networks/ Access Point Names.

Did you get a new sim chip from ATT to fit the phone?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] rilock4:
No, ATT just cut my old sim card to fit the phone.

Thanks a lot, that fixed the problem.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] rilock4:
If I do eventually update this root to the jeallybean root will I need to add that APN information again?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] aybarrap1:
Depends on the rom and if it is integrated into it.

Weird that AT&T would cut the chip instead of giving a new one.

[Xperia Z Q&A, Help & Troubleshooting] Scoregie:
Hello all,

Now this is a very simple question.

Since the Sony Xperia Z has a glass back would it be possible to engrave a picture onto the back part of the phone?.
[Xperia Z Q&A, Help & Troubleshooting] Dsteppa:
There are some stickers available for the back of the XZ. That's about it right now.

There are also some sites that let create your own sticker, but I forgot them, so can't really see if the XZ is available on those.

Edit: I meant a site like this

https://imageware.co/

Only supports myPhone and Samsung phones...:(
[Xperia Z Q&A, Help & Troubleshooting] tharealmb:
There are etching solutions that you brush on and create a froted glass like effect which you can actually feel. This does damage the glass so it's not recommended. What might be an idea, is to buy a spigen tempered glass protector and use the solution on that.

no guarantee it will work, and im not responsible for any damage, but this is the idea
[Xperia Z Q&A, Help & Troubleshooting] danw_oz:
Of course it would be, but it will cost you a lot of money since it is very hard glass (hard to engrave), jeopardise the strength of the rear glass and void your warranty
[Xperia Z Q&A, Help & Troubleshooting] RoChinu:
Watch the video and understand the concept of tempered glass.

https://www.youtube.com/watch?v=9FJUD5WB_ko&feature=youtube_gdata_player

Basically when you engrave something in the glass it will lose most of it's (strength). So I don't advice you to do so. Aluminium and plastic are a totally different story and wouldn't be as affected as the tempered glass when doing things like engraving.

Stickers as someone above me mentioned seems like the best option.
[Xperia Z Q&A, Help & Troubleshooting] xchasa:
Once glass is tempered it can't be drilled or cut so engraving is out of the question I'd say.
[Xperia Z Q&A, Help & Troubleshooting] abd_alazeez2002:
U can drill it with a very low drilling speed and feed, or it will break like normal glass.

But this will dramatically reduce back glass durability.

If I still have access to that cnc machine, I would be able to make my own back panel.
[Xperia Z Q&A, Help & Troubleshooting] Scoregie:
Sorry for the late response I've been busy. Thanks for the ideas I think I'm going to go with getting a clear plastic case and engrave that. I could probably do some sick effects going that route as well.

[Sony Xperia ZL] 7xbyte:
Hello, guys

So i got a series of problems since i unlock the simlock,

I just got my new zl a few days ago, the device was lock to Bell.

I rooted the device and after that, i got a code and enter it to the sim free status.

but here is the problems:

when i check the rooting status, it says bootloader unlock allowed: no. It will fail on if unlock straightway.

As i know, it should turns to yes, but it didn't, hwo come? Also, i flash the recovery, but it only works on first time when i get in the recovery mode.

I selected "reboot system now", and cwm point out that will flash stock recovery, no matter i selected yes or no, recovery doesn't work on next boot.

I used to have Xperia S, it was also says no, after i unlock it turns yes. It wasn't happens on my ZL! I tried to flash a new ftf and wiped all the data,

it still says no. Anyone has a same situation? Can anyone fix it?
[Sony Xperia ZL] 7xbyte:
Nobody reply? Come on guys...
[Sony Xperia ZL] nutzuTo:
I unlocked mine too but not root and still say no
[Sony Xperia ZL] 7xbyte:
Which network was ur phone locks to?
[Sony Xperia ZL] nutzuTo:
It was locked on Bell Canada, I unlocked with a code to be used on fido network
[Sony Xperia ZL] 7xbyte:
So do I, maybe Bell not allow BL to be unlock? Recovery can't even work correctly without BL unlock.

Before ZL. My XS was locked to Rogers. As I said, my XS shows BL unlock allowed after typed in the unlock code. Which mean Bell locked the

BL deadly?

I will keep following this god damn sh!*

nutzuTo, thx anyway.
[Sony Xperia ZL] strifej:
Can anyone confirm that the Bell Mobility (Canada) ZL's are permanently bootloader locked? I want to get one off the used market, but won't unless it can be fully unlocked.

Thanks
[Sony Xperia ZL] Crash338:
Maybe I didnt read the post properly but unlocking your SIM doesnt unlock the bootloader as well. It simply allows your phone to be used with different carriers. I have the C6506 from Rogers, flashed the stock Sony ROM, rooted the phone and installed TWRP and CWM. My bootloader remains locked. I dont have the need to flash the Kernel so no point in unlocking the BL. Besides, unlocking your BL voids the warranty.

Anyway, I have played with the C6506 from Bell in a store and the BL is set to "Bootloader unlock allowed: No" so its pretty safe to assume that all Bell and Rogers phones cannot be unlocked. This doesnt stop you from rooting, flashing or installing recovery.
[Sony Xperia ZL] sirsmokey:
Simlock and bl lock two different things :)

if your bl unlock says yes that means you most have one direct from factory

if your bl unlock says no you either have it on a plan or bought it full price through bell or rogers

carrier branded usually bootlocked
[Sony Xperia ZL] strifej:
Thanks for the replies guys.

I know that custom rom / root / recovery can be flashed, but coming from a galaxy nexus and n7, I'm used to being able to try out different kernels.

Can custom kernels be installed if they're part of the custom ROM? Usually the rom cook puts in the kernel of her/his choice but we can freely change after.

Anyone feel the need to change kernels or the standard one is good enough?
[Sony Xperia ZL] sirsmokey:
"Can custom kernels be installed if they're part of the custom ROM? Usually the rom cook puts in the kernel of her/his choice but we can freely change after."

Yes.When you are thinking about installing/flashing custom rom but want different kernel DL and extract the boot.img(name may vary but must end .img)

Now FLASHTOOL is sonys verision of the "Nexus Toolkit" . If you dont have adb setup download and install program to C: as well as all drivers needed. Now in the flashtool folder copy and paste the ".img" kernel into the folder named x10lib.

After double click folder labeled "x10lib" once inside the folder open command prompt window by holding left shift and right click anywhere in the opened x10lib folder.

now make sure your device is connected to your pc in fastboot mode (hold vol +) led will emit blue light.

enter command

"fastboot flash boot boot.img"

followed by

"fastboot reboot"

Anyone feel the need to change kernels or the standard one is good enough?"

yes i first used doomlords kernel (Xperia ZL) mainly for the fact that it came with cwm recovery .thus making the need to flash cwm seperatley an extra non needed step. this was before i flashed 4.2 update.
[Sony Xperia ZL] dirt_squirrel:
With that said, how would I go about flashing CM or something else aosp based with a locked BL xperia zl?

Can flashtool unlock my BL to allow this?

I ask because I clean see an option there, just haven't wanted to muck about with things I don't yet understand lol
[Sony Xperia ZL] dragonmhawk:
sadly only way to change bootloader unlock allowed to yes is to carrier unlock from ur carrier directly. anyone else and it will not change bootloaded unlock allowed no to YES. I have called bell and sony. sony told me i have to carrier unlock through bell to get it to change to yes:) only thing is. you have to have had your phone for 90 days and it costs75$ added to ur bill.

[LG Optimus 4X HD] HitTheRoadJack:
Hello, I'm new to this site and I wasn't sure where to post this but I believe this counts as a possible accessory so I decided to try it out here. I was looking for another solution to the heating problem in regards to the phone as it still does warm up a bit even after the updates to v20a and came across this:

It's a so-called graphite/graphene "ice pad" that sticks to the area inside the back cover, the only caveat is that if used on the LG Optimus 4X HD, it would cover the nfc antenna which is on the original back cover. Personally, I haven't bought and tried it yet, but am wondering if someone already has. I tried searching for it here on the forums but found nothing in regards to it. So I'm just putting this out here in case someone wants to try it, and possibly review it. I'm going to be ordering one for myself to test it out, but if someone already has tried it, please add a review on this thread.

Unfortunately, I can't post the links due to being restricted as a new user, but they are found on dhgate(dot)com and aliexpress(dot)com under the label "Cell Phone Heat Sink Magical Ice Pad Graphite/Graphene"

EDIT: Accessory has been purchased in this post.....http://xdaforums.com/showpost.php?p=41198265&postcount=14
[LG Optimus 4X HD] donkanmcklaus:
too good for be truth, did you buy it?
[LG Optimus 4X HD] HitTheRoadJack:
That's why I am going to get the cheaper one for testing purposes so it won't be a waste of cash. I've also sent an email to Panasonic for a sample of their (PGS) graphite sheet as that's what the ICE PAD reminds me of and that paper-like sheet can disperse heat up to 400 degrees F during testing. Dunno how long they'll (Panasonic USA) reply to me or how long that ICE PAD will get here since I've ordered it with free shipping. In theory and testing, the graphite (PGS) from Panasonic is an ultra-thin, lightweight, graphite film with a thermal conductivity high enough to release and diffuse the heat generated by heat sources such as CPU’s, processors, power amplifiers and cameras. Developed by Panasonic engineers, this synthetically made material was named Pyrolytic Graphite Sheet or PGS. With a thermal conductivity up to four times greater than copper, PGS is extremely pliable and can be applied to heat-source shapes even in high density mounting situations. And according to the slightly broken English on those Asian sites I've mentioned, they've described their product to do exactly what Panasonic's PGS can do and applied it to cooling smartphones.
[LG Optimus 4X HD] ljubisa_sk:
man how much i hate this heating problem
[LG Optimus 4X HD] HitTheRoadJack:
For anyone wondering about what I'm talking about when I mention the PGS by Panasonic, you can search on youtube or add this /watch?v=ZAEhyY1_czM for a look at how the PGS sheet disperses heat during testing.
[LG Optimus 4X HD] donkanmcklaus:
did you find any online store to buy it? because i only find the products on chinese web site and i don't trust them
[LG Optimus 4X HD] AlderCass:
It would probably be possible to cut a small rectangle out of it so that the NFC contact points still work.
[LG Optimus 4X HD] donkanmcklaus:
if it is truly a graphene sheet, it's possible, but if it's not, then don't
[LG Optimus 4X HD] GizModio:
Has anyone tried this magical stuff?

This stuff sounds amazing.

Wouldn't it make sense to have it directly on the CPU instead of sticking it to the back plastic?

Then maybe that way it shouldn't affect the NFC?

I would love to try this! ;)
[LG Optimus 4X HD] alekthefirst:
but then you would have to cut away the plastic to fit the sheet in
[LG Optimus 4X HD] HitTheRoadJack:
There is video in youtube about the Graphite sheet and that even cutting it won't affect it. Search for Panasonic Pyrolitic Graphite Sheets - Another Geek Moment by digikey.
[LG Optimus 4X HD] GizModio:
Who said anything about cutting? There's only 10 screws holding the back cover on!
[LG Optimus 4X HD] LGaljo:
I was watching LG Optimus 4x HD dissasembling on youtube. I noticed that the CPU is on the other side of PCB turned to screen. I don't konw were you can attach this sink. If you attach it to the top of CPU the most of heat will go to screen and this will cause bubbles under screen. On the other side of CPU is SIM PCB. Maybe you can attach it between main pcb and sim pcb.

I think you must watch the video:

[LG Optimus 4X HD] HitTheRoadJack:
OK, I just got the graphite/graphene "ice pad" yesterday and have started testing it by adding it as it supposed to be via enclosed instruction (the butchered English grammar notwithstanding). So far, close to within 24 hrs of current testing, I've seen some "slight" improvement. The phone - so far - within the span of an hour or more of solid gaming with all the cores on (software updates included) - doesn't get aggravatingly hot enough to the point where it feels as if it will blister your skin unlike before where I almost believe it will blow up. Yeah, I know it may sound like an exaggeration, but it DID get that hot prior to everything that I feared it will melt the sd card/sim card along with the plastic back cover when I first got the phone. And yes, I have already updated my phone to v20a with the obligatory root and tweaks... however, on stock ROM from LG ONLY. Currently, it does get warm but not overly "toasty" as it did out of the box. The battery still drains like a rock during super heavy use, but that is expected of quad core devices, especially on stock battery with EVERYTHING on (wifi/data/etc). I wish I had a thermal camera to really see the difference but it does "seem" to be able to dissipate heat faster. Alas, I am a noob when it comes to custom ROMs and have only rooted my unit with as-is stock v20a updated from LG so I cannot tell if there is a definite difference with people using the thing with custom ROMs. Will keep testing for the next few weeks.

And yeah, I did cut out a small portion of it to let the back cover still have access to the antenna.
[LG Optimus 4X HD] Hellothere718:
Does NFC work as before?
[LG Optimus 4X HD] HitTheRoadJack:
It does. if you can check on the pic I included, I made sure the contacts on the back cover had clear access to the contacts on the phone by cutting out a small piece of the pad .

The only update I have at the moment after almost a month of testing is that the heat rarely rises to "ouch" levels now. A long phone conversation only becomes warm now to my ear, and I did this by calling one of the worst customer service call centers I knew of with a VERY long hold time. Yes, the one where they BOUNCE you through a TON of lines before you get to the right department. :P

Sadly, however, I still can't test this via thermal imaging camera as I don't know anyone personally who owns one to really validate the rest of my tests. All I know so far is that it does help with the heat to a small degree with all the added extra precautions included in taking care of your phone. I've roughly played a two-hour game on it without the feeling of it cooking my hand. I've switched between wifi/data, etc and had the screen on from 60% brightness and up - the thing still automatically stops the brightness control when the unit gets too warm - including leaving it lit for the same amount of time straight as when I was playing a game. In fact, I did both at the same time and separate to see the difference. Only once did it go up to 100 degrees fahrenheit and slightly above that on max brightness using a flashlight app while looking at the internal indicator on as reference before I lost my nerve and let it cool off. It cooled off faster though when it was with the pad than without.

In the end, I would like to say that does kinda work, but don't take my word for it. Everyone in here has different setups for their own units so I hope this thread will get some more people interested in testing it out. For less than ten dollars US (I got mine for five with free shipping), I can say that it's an acceptable risk to test the pad out.
[LG Optimus 4X HD] Arne_B:
Where did you find it?
[LG Optimus 4X HD] HitTheRoadJack:
LOL the site still won't let me post links until I get more seniority. You can search for it under "Graphite/graphene heat sink for cell phone". I came out with sites like dhgate(dot)com and aliexpress(dot)com... I got mine from gadget-buy(dot)com for about less than 5 dollars US, it used to come with free shipping but I guess a lot of people want it because when I went back to the site, I saw a shipping price already added to it. You can probably keep on searching until you can find a cheaper one.
[LG Optimus 4X HD] Arne_B:
Ok thx. I've had bad experiences with these sites and found them on there indeed. I was kind of hoping you found it at ebay somewhere, but I couldn't find it over there.

Another question. Does the back cover still close easily?
[LG Optimus 4X HD] HitTheRoadJack:
It closes perfectly, no problems whatsoever. Just make sure you make a space/hole if the place you're going to put it on has an antenna connection. This should work on most phones. Actually, I think they sell also on ebay, but it's rare I guess. I did a recent search on ebay, and nothing came up either. It took me a while to look up those pads so I believe you have to be patient while you trawl through the net for a reliable site. I certainly took my own time to decide on whether I should get it or not, but when I got to a site that sold it for less than $5, then took the plunge on getting it. Only time will tell if it is an investment well spent or not, and the price is negligible enough to not put me in the hole.
[LG Optimus 4X HD] Arne_B:
For a while now, I'm using Chinese 'Gold' 2450mAh batteries.

I noticed how my phone was noticeably cooler with these battery's instead of the stock and another crappy Chinese battery I own.

So I tried to figure out why that was so. But actually it seemed to be very simple to me: These 'Gold' batteries are covered with a metal/aluminum sticker. While the LG and other battery has a regular plastic sticker.

The metal sticker on the gold battery touches the metal plate of the phone under the battery and transfers the heat from there away to the back cover. Spreading the internal heat of the phone better.

So I tested this by giving that other crappy Chinese battery an aluminum 'wrap'. I just wrapped it up in some aluminum foil. And this time the phone stayed cooler than before, with the same battery.

So, anyone can try this, it's totally safe. Just wrap the battery in aluminum foil (except the side where the contact pins are). And use it like that in the phone. For me the phone feels cooler after this little tweak.
[LG Optimus 4X HD] vidit_panchal:
just wraped the original lg battery with an aluminium foil.. wil report back if this helps :good:
[LG Optimus 4X HD] Arne_B:
It's not that effective as my Gold batteries though... But I think it helps a bit.

I could try to experiment with some kind of other copper materials or so.
[LG Optimus 4X HD] cickvoa:
You are aware that metal part of housing is negative, and if you put some metal around battery you could easily shorten positive and negative which could destroy your battery, or in the worst case scenario cause battery explosion and heavily hurt person who is close to phone?
[LG Optimus 4X HD] Arne_B:
I think this metal foil won't affect the signal because it's only the battery that gets the foil.

Behind the battery the phone is all metal. The battery itself is metal with a plastic sticker around it. So adding a metal foil around the battery won't affect the signal strengths of 3G, GPS or Wifi (which, I guess, are positioned above the battery, around the SIM card slot). I didn't get any negative side effects signal wise, so it should work out ok.

Yes, everyone should make 100% sure that the copper battery contact pins don't have any foil over them:

But for the rest it's safe to do.

The only problem/warning I do could think of is that when the battery is the part that gets hotter than the rest of the phone, the foil might act as an insulator instead of a cooling part. But that's something to test out.
[LG Optimus 4X HD] cickvoa:
Please tell me, how did u manage to understand that i am talking about signal? OMG. That metal part of housing, as i SAID, is negative. if you shorten that with positive pin, your battery will heat up and die in matter of seconds. That is called Short-circuit

Since youve mentioned signal, it wont be affected because there is no antenna around the battery cause if there is, it signal would be weak. Keep in mind, engineers designs phones, they know what they are doing

Battery and battery place is carefuly designed and have perfect fit, so no problem can occur

no, Al foil cannot be heat insulator, it is the complete opposite!
[LG Optimus 4X HD] Arne_B:
I thought you meant with 'metal part of housing is negative', being 'metal part of housing' the metal foil that would than be a part of the phone it's outer housing and 'negative' that it's negative to the phone's operation or so. Thus I concluded you were talking about the foil that it could have a negative effect on the phone.

I didn't know you were talking about negative polarity. Sorry.

I know..

Sure it can, that's why it's used for this: http://en.wikipedia.org/wiki/Space_blanket

And used in cooling boxes :p or on the wall of a home to reflect heat from the radiator, preventing it from getting in the wall.

[LG Optimus 4X HD] bipbop:
About this "Graphite/graphene heat sink for cell phone", could anyone post real test results ? I mean: all lg 4x hd has battery temp shown so its easy to evaluate if this magical item works or not. For example: I get +42 Celsius after heavy-playing NFS:MW for half an hour. If this item shows +39 Celsius after half an hour, I take it no questions asked ;). Just use any tool like free "battery notification+widget" from playstore:

https://play.google.com/store/apps/...sMSwxLDEsImNvbS5haXNvZnQuYmF0dGVyeXdpZGdldCJd

it will show you in notification the current battery temp.
