You can cool down device out of gas oven! And as I mentioned before electric ovens can have problems with electric waves induction (thru hot tungsten and etc). And of course it can cause/harm electrical scheme of device.
[HD2 General] the_scotsman:
I bought a TMOUS HD2 off eBay advertised as locking up, hoping to fix it and sell it on. After lots of playing around, I've found that it has this heating issue.

The phone doesn't get HOT, or even WARM...but it simply won't get past the splash screen, UNLESS I sit it on top of an ice pack....in this case, it works great.

I'm experienced in micro miniature soldering, and have *some* equipment at work.

I'll have a detailed read of your posts again and open this one up and have a look, see if I can do anything. I have a thermal gun that can direct heat onto the chip...but as you said, this is risky...

Have you made any progress recently on any process of solving this issue?

PS. Amazing work so far, your write ups are fantastic! ;)
[HD2 General] lukesan:
@booze_pistol

Wow that is some cool info and result.

Also must be a great feeling if that thing boots for the first time after the fix.

I also took a look at the equipment you mentioned. Dirt cheap, I just can't believe the evolution in 15 years time.

Maybe if you take some pictures on how you connect the temp probe that would aid people.
[HD2 General] ubejd:
thats a great news - descovery... i hope those experiance that we share here will help peoples around the globe.

thanks again all of you for being part of this thread - of course facdemol for starting everything.
[HD2 General] booze_pistol:
Thanks, and yes having a phone work again is a great feeling. The equipment is fairly affordable especially if you can use it for more than just this project. I have a need for it beyond this so it was easy for me to make a decision to invest the money,

When I get another phone, I am going to document the entire process, keep in mind folks I am a better tech than I am a photographer. :) I will show the mod to the hotplate, the placement of the probes etc. I will try to make it as detailed as possible. This solution can have a high probability of success. Yet the details are important.
[HD2 General] DTNT:
Did HTC use various soldering alloys for every HD2?! I think we have 2 versions of HD2, EU one and TMOUS one. As I remember EU is 'Made in Taiwan' and TMOUS is 'Made in China' labeled. Only restrictions or standards in these countries could cause to the alloy ingredients. And I think the alloy has the same materials as you described both in EU and TMOUS versions.
[HD2 General] motoi_bogdan:
no, the soldering is the same. However i've noticed that eu hd2's have a slightly different resin placement then tmous ones.

Still i have no reason to think that the solder material itself is different.

As they left the factory, all hd2's had a similar solder alloy chemistry. However that could change over time in the phone's normal life due to exposure to various environments. For example, prolonged expose to humidity, humid heat or salty environments (near sea/oceans) will lead to premature oxidation of the surface of the balls composing the bga connection. Although the phone itself will still be fine and working, when you're working with chip reheating that changes the story a little. The oxidized material is a poor heat conductor so a bigger amount of heat must be applied in order to partially melt it.

This translates into the fact that 2 solutions were provided (i reheated the phones at above 250 degrees - even 300 degrees while booze_pistol had success with only 200-210 degrees) and both seemed to work at some degree. However in the case of a normal hd2 with good non oxidized soldering, heating it above 230-250 degrees could be dangerous/deadly.

A good and pure tin-silver-copper alloy will melt at anything above 230-240 degrees. Oxidized alloy can withstand 360 degrees without melting, i've tested this after reading booze_pistol's results.
[HD2 General] DJ_MiX:
So best practice is to start at safe temp and if it fails, try again with slightly higher temps.
[HD2 General] motoi_bogdan:
uhm..yep

i couldn't put it better myself :p
[HD2 General] booze_pistol:
Great observations my friend, I agree with you completely. I also noted the differences in my temps and yours, and was puzzled why my results. The board that I ruined I could consistently get that solder to begin to melt at 213-218C. That is why I did it multiple times to be sure what I was seeing was actually happening, Your observations above make perfect sense though, and would explain this difference. People should realize this is never going to be a 100% fix. Any place that does rework as a business does not have that kinda success rate, they are happy with 85-90%.

I would suggest to everyone to start at that 215C mark. If you do not have success at that temp, BUT THE PHONE STILL WORKS LIKE BEFORE, then bump it up to 225C, maybe hold the temp longer, say 2-3 minutes instead of 1. If still no success, BUT THE PHONE STILL WORKS LIKE BEFORE then go 10C higher and try again. Repeat until your successful or until it becomes obvious that the board is not gonna take the fix. facdemol has pointed out that if oxidation or other factors are involved it could take higher temps to be successful. He was NOT suggesting you jump from 215C to 250-260C immediately. :) Do it in increments and you will likely find the spot where your board will respond.

In my repair of the last three phones I believe that having that bottom heat from the hotplate is a critical part of the process. It does not change the temp needed to be successful, but it does get the entire board to an even temp, it prevents any flexing or stress of the board, and allows for a smoother melt of the solder. This is absolutely an opinion, not to be taken as a fact. It works well so far, I just need more phones to be able to continue the work, and see what the success rate can be. It should be noted that a reball template is available for this processor. It is not beyond the realm of possibility to reball this chiip, but that is an entirely different monster, and shall be saved for a different time.

This is facdemol's work, he got all this started, and my success is only due to all of his work on this problem. Many, many thanks!
[HD2 General] DTNT:
@booze_pistol

How do you think, how many HD2s needed to be experimented to come for some constant results in your experiments? I think after 5-6 repaired HD2s you can easily write "User's Manual" how to cook HD2 with successful results. I mean exact temp, exact timing in the oven and etc.

@booze_pistol @facdemol

Most of HD2 users couldnt have access to temp probes or other high-tech gadgets (termometr and etc). So you should think how regular users can Cook his/her device with only Temp indicator in gas/electric oven/hotplate's camera/plate. Would be great if you do so.

Now we have 2 experimentators who did success in their results. And I think solution of the problem is in a finish line!!!
[HD2 General] abufaris:
its work now

hello my freinds,i wont to share u all with my experiment ,after reading your threads i decided to be a phone surgery :) so,i took my hd2 board and put it in electric oven for 10 minutes on 100 degree,after that i raised the heat to 200 by keeping board inside for 13 minutes,i smell smoke come out of board:eek:, don't worry it was the cooling shield:D then i took it and leave it to cool,then reconnect every thing,its working good now yes it back like the old times , even gps come back to live:D ,!!but:confused::confused::confused::eek: i found the screen colors is not normal its become yellowish now:mad: i reconnected the parts again ,cause i thought maybe the flex cable for screen is not connected well,but:( that's mean board heating and freezing is fixed but screen colors is the problem now:confused:,any way my friends ,its soldering ,heating and freezing caused by bad chips soldering,

hd2 is great phone i ever used,but i think its time to say goodbye now, ,

hope HTC company could read our threads ,to void having like this troubles in the other phones,my hd2 coast me 800 us dollars ,cause we have no dealers here,only black market,and now worth nothing, :) ,

thank u all:)
[HD2 General] Ev0luti0n_:
it is so nice to see everybody trying to find the best way to insert their device on the oven to cook it :lol: LOL
[HD2 General] motoi_bogdan:
@abufaris you partially made it. The display i/o pins are also contained in the bga matrix that you were trying to fix by heating. So.. you managed to fix the freezes and other stuff but broken a few other contacts in the process, in this case some of the display i/o connections. Because of this, the display tft matrix is not biased properly so you see different strange things/colors.

First of all begin by carefully checking the display connector on the motherboard, the display itself or it's ribbon cable (flex cable). Check to see if any damage has occurred to them during disassembly. ONLY after making sure there is nothing visibly wrong with them (of course the ideal thing would have been to check the motherboard with another hd2 display) proceed to another heating round using the same settings as before.

One note: you should have REMOVED the metallic shields over the cpu area and on the opposite side before heating up the chip. Without any way to escape, too much heat can build up inside those small enclosures and you can risk thermal damage to the chip or it's bga soldering. Next time you reheat it, please remove those things first.

Good luck.
[HD2 General] DTNT:
Do you think this screen mulfunction came from cable or i/o connections? Maybe overheated chip work unproper and giving such display issues?! Besides, Abufaris kept his device more than recommended by You and Booze_Pistol! Can it be a reason for such mulfunctioning?!

@Abufaris

Good to hear such news. Try as Facdemol advised you and than comeback with results.
[HD2 General] lukesan:
Reading through all these threads about not working things like GPS, buttons etc I wonder how much % of the HD2's are now suffering from these issues.

@facdemol: sent you an email
[HD2 General] DTNT:
Difficult (impossible) to say! And because this thread can only be read by english speaking (or knowing) readers, and think how many who doesnt know english.

Would be great if after some success examples and ideal cooking receipt, somebody will post the translations of results in his/her own language in local forums. Of course with the direct link to this post and with thanks to Facdemol and Booze_Pistol! :)
[HD2 General] DTNT:
@all

today is hot in our city. So when I was coming back from the lunch an idea came to me related this topic.

In childhood everybody used to play lenses in a sunlight days and burned a lot of things with the ray of light. :) So how do you think, can I use lenses to heatup my chip and deserve a success?! (In my country there are a lot of sunny days:))

Anyways, I'm going to cook my HD2 chip this sunday (by start of F1 Great Britain GP) and Inshallah it should work properly.
[HD2 General] ubejd:
well thats a new and funny idea :D , i dont know what to say, im afraid you could damage your phone , but inshAllah you will succeed my bro.
[HD2 General] DTNT:
As promised, yesterday I cooked my HD2's processor chip. (And Alonso won in Silverstone :D) But unfortunately while disassembling device I torn off hard buttons bus. And now cannot switch on device. (Anyone know how to turn on without hard buttons:)) In a days I'm planning to replace this bus and try to work out with the device.

Later will come with all details of the process.

Help!

guys... i ran into a problem yday ... was using the TyphooN CyanogenMod 7 v2.5 standard build when it occurred... after setting up the rom, tried the new cam with zoom function for vol keys... cam worked nicely and that was that for the time being... some time later, the home, windows key and backspace key became non-responsive and the vol key behaved as if it was always pressed down.. it wont increase the vol but will only decrease....except for the non-responsive keys, rom was fine...to correct it, i tried everything from rebooting to reloading diff roms... later tried a a wp7 build hoping it would alter the key mapping.. but nothing worked... also, when inside a rom (android or wp7), green button wont wake up the screen...

in magldr menu, there is a slight screen flicker... looks like screen focus is always moving down in a cyclic manner... as if the vol down key is kept pressed... i could hold the vol up key n select menu options with green button but only have to wait for the selection to come to the correct menu option n then quickly select it...

has anyone seen this issue before? any suggestion on how i could recover? is it a hardware error?

all suggestions n comments are welcome...

thanks!
