HI everyboy
I've got a problem with my Qtek wish someone can help me
So, i'm asking about a braid (wish it's the right word) compatible with my Qtek, the problem is that hear i can't find original one, so i'm asking about any other phone that got the same.
Wish you've got a idea
Thx in advance

What?
What do you mean with braid?
Here you can't? or you can't hear?
Please give us more info men!

Hi and thx for the quick replay

Flexible.... well i know its hard to get one of this parts cause are very weak... i has one... how many does you thing it costs?

hey Que...nice pimping with your BA..love it man!
basically if the flex that connects the lcd to the board is damaged it is more advisable to replace the whole lcd itself but of course it's kinda expensive. I got the same problem way way back but sadly did not find any replacement here(phil) for the flex so I was forced to buy a new lcd....

HI
thx for the replies, thx i think i'll never forget it the FLEX, i don't know how much it cost, even i can't but one from europe or USA, cuz i'm living in algeria, so there's no way, i was just thinking that maybe there's some cellphones that got the same flex so i'll just use. if you have any idea, please inform me.
Thx

Mmmmmm?
I think there are two different flex types i mean version!
My bro has a BA but he bricks it when he tried to change the Audio plug in... I know he is a fool
BTW if you want... I can send you the flex just pay the shipping cost... let me check that flex maybe is hard solded to the display...
I toldyou that history cause i tried to connect that display to my BA and it wont works... i think there are differnete revision versions of the display or mother board... ou can check the Part Number behind the flex... may is the same i got... what do you think?

JTAG Wiggler

Hi.
I'm planning on making a JTAG Wiggler cable for my G1. I'm using the modified scheme supplied by Scholbert on post #412 of this thread:
http://forum.xda-developers.com/showthread.php?t=591048&highlight=jtag
I made an image of this scheme with other supplied in the same thread (for VCC).

I have some questions regarding the type of resistors and capacitors...
-What kind of cap are C1 and C2? Does electrolitic works OK?
-R1 and R2 (bottom right) are SMD or doesnt make a difference?
-LM317, is there any problem on what kind of package is it?
.R3 (bottom) is SMD... but the value is 54ohm?
Hope you can help me a little on thiis one.
Best Regards.

Read on another thread that jtag can also be used to unbrick?

Yes, JTAG can be used to unbrick phones...
Let's hope someone can help me with the first Wiggler, after that I would gladly post a guide with tons of pictures if I succeed obviously.
Best Regards.

The caps are regular caps, but I do not see why you couldn't use electrolytic caps.
Resistors: there is no difference between the value of SMD and through-hole resistor, so see fit which one to use.
The LM317 is available in several packages: sot223, to-252, to220, to-263 to-39, to-3..
I would recommend the to-220.
R3 is 56 ohms according to schematic.
Regards,
EqX

Thanks for your answer...
Actually I choose the LM317LZ, it is the smaller one so let's hope it can dissipate the heat correctly.
From my very limited knowledge, this second scheme I post would be correct, using electrolytic cap. and pass throu resistors.
Best Regards.

far beyond my knowledge to do, i would pay someone to do it for my though

those can be bought for a few bucks on ebay.
But I personally would go for a buspirate (27$ shipped):
http://www.seeedstudio.com/depot/bus-pirate-v3-assembled-p-609.html?cPath=61_68
Buspirate can not only be used as JTAG, but as so much more (simply by changing it's firmware )
(see the link or Dangerous prototypes page for more details)
And it is open source hard- and software..
(I also bought the probe set so I didn't have to mess with other headers etc.)

The problem with that is I do not know how to JTAG using that board...
My only chance is get the Wiggler done, use the cfg for OpenOCD the experts posted on this thread: http://forum.xda-developers.com/showthread.php?t=591048&highlight=jtag&page=64
And learn something...
Bye

BusPirate & openOCD totally possible

UPDATE!
This is the final scheme:
According to Scholbert it is correct.
Best Regards.

[Q] What should I do with this screen?

Hello,
I've had my desire for almost a year now, and it broke yesterday... I was playing with my 6-year old nephews, and my desire fell out of my pocket. I didn't know that it was broken until I wanted to check my whatsapp a few hours later, and when I did, the screen was like this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
... (lol the image is way too big)The touchscreen is working fine, I can turn it on and unlock it, I can even send an whatsapp, because I knew where the icon was. So what should I do with it? Repair it if it's possible? How much would that cost? I now have an iPhone 3gs as stand-in, should I keep that for as long as my contract lasts (1 year)? Or should I buy a new one? If so, which one would you advise me? A cheap one please, as I want to save for the PS4 later this year.
I'm running Sandvolds ICS for those that want to know...
Thanks!

There's a possibility that the screen cable is slightly disconnected. Try to disassemble the phone, and check the cable.

Thanks for the reply, I'll give it a try
Edit: Yeah I tried to take it apart, seems I've got no T5 screwdriver at home... Basically, if I would take it apart I would have not any idea what te screen cable is... Is it the LCD connecter? I do know quite a bit about software and that sort of stuff, but I'm a n00b at replacing hardware :S

I had the exact same screen on my Desire :silly:
That screen is broken and you need to replace it. I would recomend a professional to do it because I tried to do it myself and I destroyed my phone. And the other thing if you decide to go on with replacement - Desire had two different screen types and every type had one or two subtypes which are NOT compatible with each other so you need to know exactly what type of screen you have

Cuted cable from display assembly

Hey all,
my galaxy note wont charge. So i opened the device to fix it. The good thing is, that the device now charge. The bad thing is that i cuted the cable for the display assembly.

This is the thing which is broken by me. The right cable is cuted.
Is there any option two replace just the cable instead of buying a whole new display assembly?
Thanks for your help and sorry for my bad english.

Thank you! I try it!

Hey,
the cable arrived today. I tried to get it build in but no change. It's too tricky. I think it's not possible to get the screen off without a brick. If someone can put the screen away without bricking it, it's very hard to connect the new cable to the screen.
The phone is dead. Maybe i found a cheap damaged phone with a working screen on ebay... We will see.

I will try it.

Hope you can fix the phone asap

Tab freezes/green strips/battery drop suddenly

Ok guys there are users who faces the same problems with tab t705/700
1 sudden battery drop
2 green strips on display
3 freeze and reeboot
4 when network changes the green strips come
5 cam flash not work
this is not an software prob definitely (hardware prob faulty battery connector)
i tried on both kk and lp
the solution :d
if u r a nonrooted user
dont waste ur time on cleanning caches, trying recovery etc
replace\repair the tab asap at samsung store
for root users
the problem is in the battery connector(where it connects to the mainboard)
find an good phone mechanic (u dont need an expert for this )
ask him to resolder ur battery connector to the mainboard(btw i have gave 3$ for that)
iam using t705
and get an amazing battery life
it has been 3 months and not a single complain/problem from tab

Plenty seem to get this issue with the 8.5 model, but nobody ever actually posts a pic of the problem.

This is the battery connector, actually the from the 8.4", but the 10.5" should look the same.
Samsung service centers have been know to replace the battery connector with a more heavy duty version during a repair.

The issue seems limited to 8.4 models dont think ive seen a report of anyone with a 10.5 having the same problem.

As I have an 10.5" i hope you are right, below is the post about replacing the battery connector.
