I'm already failing thats why i asked for help

I don't know if here have latex support...
And my english is really horrible, but I'll try to give you a hint...
First you will need to know about 2º degree equation, about rational/irrational roots...
Things like these:
(x-2)² = (x-2).(x-2) = x(x-2) + (-2(x-2)) = x² -4x +4
I don't know if these are the things that you are searching for, but if you have the hint in your mind you can solve easy these problems....

Those are pretty easy.
I would like to explain how to get the answer, but it's hard not being able to type out fractions (without doing this: x/y).
So I Googled "discriminants and roots" for you and came up with this site.
Good luck.

Is it possible yes . Who makes the parts would be the better question. And the availability of these parts would be the next question. After you have those solved then you will need a bit of electronic skills to open the phone, remove or de-solder the present parts and then do the reverse to install the new parts.

Yes .. It will work fine if you change them correctly. Now if you have never done such a thing make sure you cover your tracks when opening the cell so you can try and get it covered under the insurance I hope you have. Or at least thats what I would do ...
let me tell u one thing.... i have never done this before but there is no insurance in Pakistan but it wont be such a big problem for me becoz my cousin is a electrical gadgets expert he does these kind of things so i would like to trust him and i'm not going do this now ill do it when Wizard reselling price is not more than Rs.5000 or $85, but still thanks for help.

Can Call Duration be cleared... anyone know? Any tweaks / proggies to assist?

Start, Settings, System, Device Information... Call Duration. How do you wipe those figures from your handset folks? Must be a way somehow but how?!
Please gimme a clue cus i'm trying to sell my handset 'as new' and even though i've only used the phone for about 2 hours total, in and outgoing, it'd still be nice to have no comebacks with it.
Besides... someone else might need this info for some other reason to so if you know... shout loudly please!!!!!!!!
By the way... ROM changing doesn't do a thing. Looks like it's part of the handset's brain so... well i dunno now actually! HELP!!! lol

There are 3 command you can enter:
Code:
[email protected]?1
[email protected]?0
[email protected]=270F,270F
These do the following
[email protected]?1 - Shows Outbound time in HEX
[email protected]?0 - Shows Inbound time in HEX
[email protected]=270F,270F - Reset both timers to zero.

lol @ chilax!
Loving it! Thanks Dave. Trying it now so more than likely i'll get back to you saying i c*cked it up!!!
Enjoy lunch!!!
TSS
P.S. Added you to msn if that's ok. Hope i've not overstepped my bounds there
Kewl, let me know if it works.
Now, how do I set my call duration back to what it was before
Dave
I use ATcommander and send
[email protected]?1 and [email protected]?0 and
it's OK, but when i send [email protected]=270F,270F i see ERROR
I've installed Hard-SPL
Why?
Thanks
I knew it......
... when i enter the 270F,270F it says ERROR.
Correct me if i'm wrong Dave. You simply type in what you told me to, namely the AT code and hit send, yes?
I am truly amazed at the amount of help offered to someone who wants to sell a used phone as new. Spare a thought for the poor sod who will be conned into this. And please don't start the "it's like new business", you know it isn't.
You might need security unlock or Hard SPL at least to do this.
So if you have HardSPL already, you possibly need security unlock. Security unlock is still been worked on at the moment, so you could be stuck for a while.
Sorry, but I don't own a Blackstone to test on.
Thanks

Excuse me? Who the hell are you and what are you bringing to this thread apart from negativity? Go and annoy someone else. If you haven't got anything of use to say, sling your hook.
And just to further correct you... it's 3 days old and not been out of it's pouch for more than 90 minutes or so. Why i'm even bothering to explain that to you i have no idea.

Not a problem Dave. Thanks for all your efforts. I'm sure OTHER users may find this thread of interest... unlike SOME i could mention.
Oh, maybe this other option i mentioned to you on PM could help? If that's factory unlocked, that might do it, mightn't it? Just a thought off the top of the old noggin like!!! lol

What I am trying to bring to this thread is a bit of ethos and concern for the guy to whom you will flock your wears. 3 days or 133 days you have no right to clock it and present it for something it isn't. It is also illegal.

Illegal? Well 2 things.
1. As you'll have noticed, i'm new to all this side of things as far as XDA goes so i was unaware of that.
2. Tell that to everyone else and quit hassling me.
The ethics and ethos of this have been discussed everytime a thread like this is started.
As this is not possible at the moment I see no need for this discussion to continue.

I am a computer engineer and i think there is a hardware solution for this

Yes there is,..
1. Dig a hole in the ground
2. Put it in there.
3. Say your prayers and hope it goes to android heaven
Its bricked/dead/not gunna work ANYMORE FOREVER....

The small-mindedness of people in this forum is really disturbing. Don't worry too much about them.

they don't requite English 101 to become a computer engineer? and please have common courtesy by not trying to hurt my eyes even more when i read your post.
no, its not been solved yet. honestly? i don't think it ever will. whoever figures it out will probably get a good paying job with htc because i doubt they know how as well. if they did, they wouldn't replace phones. they would just teach people how to fix it.

Yes, correct. However, do you really think if HTC knew how to unbrick phones they would let you send in your bricked one for a brand new one? No. They'd either walk you through it, or tel you to send it in, they would fix it, and send it back.
Also, you do know the myTouch is like 400 dollars without a contract? Theres no way any company wants to loose 400 dollars because of a warranty.

[Q] Help Needed BIG time

Not entirely sure but can you get into the 3 button download mode? (Guide in general section). Also posting in the dev section will not help as that section is for developers not for questions about phone problems.

The heat trick is a legend...made by ppl who actually have not really bricked or semi-bricked their phones (just a lucky coincidence). He'll only manage to kill his phone for real.

kinda reminds me of the old xbox has broken heat trick. if it did work i think the life of my fone would be shortened. it seems to have totally died now (guess coz cant charge) so im going to have a my fones stopped working chat. i think im still in the 28 days so hopefully they will just replace it. thanks all for the help
and sorry if seemed fussy - i know its my fault but there has always been some kind of software fix with my old htc's guess i rid on hope lol

I seem to be getting that impression too. on a worse case with any of my HTC phones i ever had i could do something to get it working. and i have had some **** ups happen. this was a stupid mistake and im sure on a forum where we have oms posted for both i cant be the first person to click the wrong one as im getting the idea they are simular but hey its a brick now. so carphonewarehouse i go. and just hope they cant switch it on and see the at&t screen lmao.
I had a similar result a couple of weeks back after trying to flash hardcore's speedmod kernel CWM version in Odin - not very sensible...
Couldn't get into download mode at all. After panicking for a couple of hours, I removed the battery for 2 hours, reinserted it and all was good - i.e., got download mode back.
Worth a try, you're not going to make it any worse. Hopefully... Good luck.

Best way to become scholar

WHAT Is IMPORTANT IN Us is NEVER LET ANYONE KNOW HOW WE STUDY
I AM SHARING THIS WITH U SO THAT IT SHOULD NOW BECOME A THING KNOWN to everyone
First calm down before studing.
BE CURIOUS ABOUT WHAT U WILL LEARN.
We should study a chapter on three parts first knowing the concept then get to details and then write it down once
1.get to the concept
This is very important as u should know the concept and what matter are u learning be curious and understand the situation the thong is and to get to a level of a scholar, get the thing ur learning in some other situation it will not be given in the text, it actually bends ur mind and makes u think
Get the details.
Details are very important as they help u to get extra marks as everyone dosrnt try to focus on it and try to neglect it
Use details as a plus point to ur studies and as a secrete wepon too.
After every one hour don't forget to take a break of 10 minutes as scientiests says this too.
Write down ur ans once.
Writing concepts can help u to make a pprint of what u have learnt.
This is known as image framing. In our daily life we memorise many images but all of them are stored on our ram we gave to convert it to fixed memory so write without looking.
Have fun play on PC relax simultaneously as stressing too much will make u mad.
Iisten to what ur parents say and focus on ur goal
AND MOST IMPORTANT THROW UR ELECTRONIC EQ 3 MONTHS BEFORE EXAMS
