stepped on my at&t 8525 :( - 8525, TyTN, MDA Vario II, JasJam General

While carrying a HEAVY 32" CRT TV my phone fell out of my pocket and I inadvertently stepped on it while wearing steel-toe work boots. The phone seemed to work even though the screen was cracked... I could get the comm manager up and push where I remembered the vibrate button to be and it seemed to work.
I put in a new LCD panel and all I got was a boot sound and a white screen, so I also tried a new flex cable with the same results. I also can't seem to get any kind of reaction out of it like before so I'm not really sure where to go next.
I'd really like to fix this thing but it's not worth putting an arm and a leg into it.
What do you guys think I should try? Anything I'm overlooking or something? Any help would be appreciated.
Thanks,
Noah

You need to be sure the new LCD is made by the same company as the old one. This is ESSENTIAL. See this thread:
http://forum.xda-developers.com/showthread.php?t=485961
In particular my post no 4.

Thanks for that tip, but both LCD panels seem identical except for the stickers, but the model numbers on the stickers are both the same. One has a larger print than the other. The number on both is TD028STEB1, and they both have a black ribbon cable.
Hmm. I just noticed. The old LCD panel says P/N 60H00037-01M and the new one says P/N 60H00037-00M. Even though these are both the Toppoly LCD panel could this mean they are incompatible?
Thanks,
Noah

Well, I think those two are compatible (bith Toppoly). So assuming the new one is ok as a replacment it leaves a couple of possibilities I think:
1
The connectors need to be re-checked.
OR
2
in the worst case scenario there is damaged to the d/pad board. A chip on the d/pad board is crucial for the functioning of the screen. Unfortunately this chip can be prone to micro fractures in the soldering between it and the board. (Even with normal button pressing many members have had a "white screen because of this cracking). Some members have found that putting a little padding on top of the chip to push it against the d/pad board can be used as a solution. (I think though, that this should be vied as a temporary solution).
Just my thoughts.

2 phones / 2 issues / trying to make one phone work.

If anyone can offer any advise/assistance, it would be greatly appreciated!!
I have 2 AT&T branded 8525 phones. Both have issues and I assumed I could make one good working phone from them.
Phone 1 had a touchscreen issue. It is not responsive what-so-ever. I tried the credit card trick, cleaning out the edges, hard reset, soft reset, etc... nothing seems to make it respond at all. Reflashed the ROM, but of course I am stuck at the "Touch Screen to Begin" screen.
Phone 2 works just fine, but when plugging in the mini usb charger the screen starts to fade to white (with many vertical lines appearing...but eventually the screen goes to white). If you wiggle the charger, it will clear up, but then go back to the fading white screen. If you leave it long enough on the white screen, it will lock up.
So I thought I could take the known good LCD from phone 2 and put it in phone 1. Yesterday I took both phones apart to do this. I placed the good LCD in the phone that had the possibly bad LCD. Put it all back together and found the touchscreen still does not work . So perhaps the LCD was fine and it was something else. I then decided to just take the motherboard from phone 2 and put it in phone 1 along with the LCD I just replaced (effictively moving the lcd and motherboard over to a new case). Same issue... touchscreen does not work. I assume moving the parts around eliminates a loose connection of some sort. I did make sure the ribbon cables were properly aligned and secured well. I am guessing something is wrong on the motherboard.
Does anyone have an idea of what could be wrong to prevent the touchscreen from working?
Oh...moving both the motherboard and lcd with the whitescreen issue(phone 2) over to the other phone (phone 1) casing didn't change anything at all either...so I assume that is not a connection issue with the cables. I also looked closely at the mini USB connector on the motherboard to see if there was bad solder or something that was making it act up. I am guessing bad hardware in both phones, but was hoping I could somehow make one of these phones work and junk the other. Sounds like I may have to junk both as the cost of parts is probably is silly.
Thanks for any help!!

X1 Ribbon cable - what happens and a fix I came up with!

Hi, I come on here quite a lot for information as it's an amazing resource! This time however, I'm attempting to give something back!
I experienced the "black screen on slide out" on Monday. Phone completely screwed. I've also had a few droppages and had it apart once before so there's no way warranty is gonna help!
I stripped it down and soon discovered what it is that actually fails on the ribbon. The coating had worn through due to rubbing on something during the slide out / in process. it had been playing up for a while, probably due to shorting out on the metal case, but now the tracks (aluminium?) had worn right down.....
In pic 1 i've circled the worn area. The shiny section is where i'd tried taping over it to prevent shorting, before i realised the tracks were gone.
Got an almost new one off ebay for 15 quid and, realising it was going to happen again, came up with a solution that, so far, looks like it will work....
A while back I bought some "anti rattle felt" for my car's dashboard - really thin and strong self adhesive felt to prevent squeaking joins between dash sections. I cut a piece of this and stuck it to the new ribbon. Once this stuff is on it's well stuck, by the way!
See pic 2 for the modded ribbon cable.
On reassembly everything is working just fine so far! Here's hoping that it lasts longer than 6 months this time!
Just need a new casing now as mine is decidedly second hand!
Hope this turns out to be of use to someone!
cool story bro
when i took apart my xperia to replace the housing this seemed like a really weak point in the device. glad to see someone who has had the problem has been able to fix it
Why does the screen go black?
Hi,
When the coating wears off the ribbon cable it exposes the tracks in it. when you slide the keyboard out the exposed tracks short out on the metal casing and the screen loses it's input signal.
thats whats happened on mine at least and i presume quite a few others?
HTH!
Update:
That's interesting: My phone was also losing signal with the keyboard out, and occasionally while closed up as well. It would just randomly drop to "no signal" for a few seconds.
It hasn't done it since replacing the ribbon cable.....could be coincidental of course.
I'm having the same problem
It just started a week ago and I got the phone in January off of ebay. I'm new to opening up the phone so could anyone help me find the correct tools or have a link to a site with pictured instructions?
I noticed that the sliding mechanism started to go loose about 4-5 months ago but didn't expect the screen not respond in landscape mode. I have yet to see the other symptoms you all are referring to. I would like to fix this before it get worse.
In mine case it went totaly black after one week of this problem... You have all the instruction on youtube, there is where i looked. For tools you can be inovative, but the exactly right ones come with housings from ebay, it is only 15EUR, and i bet you have some cracks so it wouldn't hurt replacing. That is what i did, along with ordering new sliding mechanizm, and new ribbon cable.
I am open for ideas to prevent my ribbon cable from being cut at it weakest point again.
I'm assuming my flex ribbon went bad yesterday, since sliding the keypad out causes my screen to shut off.
Already ordered a cable off ebay and will attempt to replace it myself :O
Replaced my flex ribbon cable with one I bought on eBay. The screen doesn't turn on at all now, which leads me to believe the cable I was sent is defective. Put the old one back in and it works okay, less landscape mode. ughhh what a pain.
great tips! my input is I bought a case off of ebay that was ~60$ and everything actually fit fine for me...so I wouldn't discount every seller but you do get what you pay for, the 15$ cases are probablly the ones that will give you problems
I working in a mobilephone repair center if anyone need help drop me a priv... i able to get 2nd hand or even brand new components
Replaced the flex ribbon cable -
I got my flex ribbon cable a few weeks ago and took it to my local repair shop. They replaced it but the LCD screen/optical joystick receives no power. The touchscreen and everything else on the phone works just fine now. I thought it was a defective item so it was exchanged with a new one.
Got the repair shop to replace it again and the outcome still remains the same as the first.
Theres no light coming from the screen nor the side illumination.
I just told the repair shop to just place the original back in for the mean time.
Before the repairs, there would be a flicker of white light and random illuminations. Now there's no lights at all except the power botton.
Could it be defective a batch that the seller was sending out? or the repair shop's mistake and is playing dumb so they do not have to admint fault?
Hopefully there's an easy fix to this problem.
-Also I did inspect the ribbon before and after the repair. looks new as the OEm
Can anybody help me out with this new problem after replacing the cable -
perhaps you should try a hard reset. Ive had problems in the past where the optical joystick and the illuminators did not work, and that worked for me.
On the other hand, the top illuminators are on the same piece of hardware as the flex cable that was replaced, so a faulty flex cable is possible. The bottom illuminators are on the circuit board that the optical joystick attaches to, separate but connected to the flex cable.
Ive recently replaced my flex cable and touchscreen. The experience i had with the faulty touch screen was that it appeared to receive no power, but was in fact displaying a dark backlit illumination that could only be seen in the dark. At the same time however, the screen did not display anything. I'm not sure if this is similar to your experience, but if so then your touchscreen would need to be replaced.
ive done all repairs on the xperia myself, and one thing ive discovered is if something doesnt work right after a repair, simply disassembling it and reassembling it to make sure all the connections are properly done has worked for me in the past.
"Before the repairs, there would be a flicker of white light and random illuminations. Now there's no lights at all except the power button."
Now when you say the power button, do you mean that a red light appears under it?
I dont know if i can come to a conclusion or that i can help (or have helped) you come to a conclusion, but i can only assure you that the xperia acts out in strange and weird ways.
Good Luck!

Thanks for the links. I've tried the hardreset and restoring the original rom but the issue is still there. It's really bugging me that everything works but the LCD screen. I'm currently using MyMobiler to use my phone. The touch screen works fine and so does the soft keys. Just no power for the lights. I might just give up and wait for another phone that catches my eye and then tinker with the xperia myself. but if anyone got a solution or want me to test something then I'll give it a try.
My warranty is no longer affective so I'll use my phone as a tester to help others with any problems.
TRIONDAVE, how's your Xperia running now with the cable mod that you did? Its been 6 months since you created the thread. I hope you're still around.
My Xperia X1 works nearly fine, except for the keyboard issues, so I'm thinking of opening it up. If your Ribbon mod helped I might just do it too once I've got it opened. Mine has a MOUNTain of cracks though, and the battery compartment itself is cracked on both side enough to make the compartment CURVED. Hence the Battery cover doesn't sit well.
I'm looking around for broken Xperias which I might be able to use to change the internal cracked casing. Lets see.

My thoughts exactly.
Hello guys, I am in need of real help over here!
Its just that Ive replaced my ribbon cable, the old one got screwd up.
However I got done for 10 minutes ago, tried to start up the phone.. without success :,(
The ribbon cable doesnt have anything to do with the start up, only the screen am I correct? Cause I cannot even start my phone..
Ive connected the charger, but when I remove the battery it shows a red light, meaning no battery, correct?
So what may the problem be exactly? Maybe the battery is all dead, or?
PLEASE HELP!
for the people with ribbon failures how long have you had the phone before it occurred ? im just interested on the cables lifespan.
mine is fine so far but i have noticed the slider is flimsy and rocks left and right.

What else can I replace? (Screen issue)

My screen started turning white awhile back. I now have a screen and a ribbon cable.
I replaced the screen first, and the new screen shows only white. Probably the cable, right?
Then I replaced the ribbon (keeping the new screen in) and still got only white.
Hooked the old screen back up with the new ribbon cable, and now I have a working screen, but the colors are horribly washed out and it looks like it has lines of white every other line or so.
Is there anything else I can do? Should I give up? Suggestions?
Thanks guys, I don't know if I've ever posted here, but you've been a great help for many years!

Assuming the cable connectors are good and clean, it is now generally accepted that white screen issues are caused by faulty chip connections on the d-pad daughter board. If you can replace that at a reasonable cost, it might be worth it.
Your new screen may have been white because either:
1
The d-pad board is indeed faulty
OR 2
The new screen although made for the Hermes is not an exact match. You MUST replace like with like. There were at least 3 different and NON-compatible screens made for the Hermes (by different manufacturers - Toppoly, Samsung etc). The only easy way to know if the new screen is the correct one is to compare the code numbers printed on the rear of the screens.

I'll have to keep a eye on eBay for a d-pad... There are a few parts phones out there now, but I can't tell if they have the right parts inside or not,
Does the serial number tell me what screen components it uses (IE Serial number XXXX+ came with the black flex, XXXX and below came with the white flex, etc?)

It may be that you can match screen to seriel number, but so far as I know, nobody has done that detailed matchiing task. So unfortunately at the moment, the only way to tell is to dismantle and see the number.
A thought crossed my mind about the d-pad board. Have you read the long thread about fixing the whitescreen problem. One reasonably successful solution is to place a little padding on a d-pad chip to press it against it's board. (simply put the issue arises from fractured chip solder joints - caused by finger presses on the d-pad). I don't suggest this as a permanent fix, but if such padding caused the whitescreen to disappear, then at least you could be sure it is a d-pad problem.
Mike
My boss is a parnter in a Electric car conversion company, and they build all sorts of small circuitry (including surface mount stuff) so I'll take the board into one of them and ask if they'll re-do the solder joints for me, thanks.
I never posted here, but I got all the information I used to try and fix it here, but in all my searches, I don't think I ever read anything about the Dpad untill the past few days... So thanks alot for that...

One thing if you have the solder reflowed (obvious to some but not all!!) remember to peel off the sticky plastic layer on the opposite side or you'll end up with a sticky mess

Touch HD (Blackstone) Screen & touch repair, pics and tips inside!

Hi XDA peeps.
I would like to share my notes and pictures of my recent repair i performed on my touch HD. If you end up suffering from the Newton_Ring problem or cracked lcd, and decide to purchase a factory assembled LCD + Digitizer, you can use the Official Service manual and this thread, to perform the repair.
The Battery and the Battery cover have been removed.
Lower mainboard cover and inner housing have been removed
the Digitizer & LCD (preassembled) replacement Part, beside the damaged Blackstone.
Removal of the GPS Coaxial cabling.
I'll skip past the wifi coax removal, but will like to note that you will find a spare coax socket on the mainboard next to the wifi one, so dont get those mixed up when reassembling it!!
both Coax cables removed. (bad quality picture)
Removal of the Ribbons Mylar
this is the removal of the Ribbon plug.
Removal of the Volume buttons and its petite PCB. Take your time, dont break the ribbons or damage the pcb trying to remove this.
Removal of the mainboard phillips screw.
Power PCB slot removal, this ones tricky.
Unplugging of the 5 megapixel main camera, a nice and easy step.
Note: Please be aware that the whole Top PCB is very fragile and does actually bend, hence the term Flex PCB, be gentle with this component.
You wont see this part of the repair listed in the official manual, infact when I had a google around, there was little to no information on howto perform this anywhere.
Let me make one thing certain, if you've just spent like an hour on the above, while following the Official service manual, squinting at the poor quality photos (or my poor quality photos ) and you're feeling a little impatient, take a decent break before attempting the above!
Because, for the above procedure, you need to tear off the 3 layers of Digitizer and LCD from the front of the phone, if you don't take your time with how you do it, you'll dent your frame (a lot).
you won't find this in the service manual, if you worked out its significantly easier do a factory pre-assembled Digi+LCD replacement, and if you don't purchase the housing along with LCD and Digitizer, then you'll need to take the front Speaker piece grill, and transplant it to the new part.
Note: that you don't need to add any extra glue to perform any of this.
Next you simply gently fold a ribbon so you can place the new part into the old frame, and you'll end up with something like this:
I also did a lot of very minor aesthetic damage to the inner area of the frame, between the frame and the touch screen.
Take your time to prevent this, also if you don't care for the old part at all and aren't replacing a LCD or Digitizer standalone, you can pretty much gain access to the layers from one corner then tear the layers away from the glue with your hands.
Next proceed to rebuild the phone following the above in reverse or keep following the service manual (or both, is probably the best way IMO)
Note: Don't forget to place the camera back into the reassembly as you're re adding the coax wires. The service manual won't instruct you to do this.
Install back your flexible and mainboard pcb. as above.
The above is with all the boards, cables and camera installed back into place.
Verify the replacement part is good before fastening in the shell casings.
Lastly the two shells are fastened back on and the battery is put back into place.
Note: When installing the main shell, be very considerate of the camera, while at the same time, ensuring that none of the coaxial or the vibrator cable falls out of their desired places.
OK, if you have the HTC Service manual PDF, and need to repair your Blackstone (and want to DIY), it can be done albeit some instructions are clearly omitted from the official service manual.
One final note, When researching on what part to use to perform the repair of my Blackstone mobile, I read a great many people have attempted to repair their Blackstones and failed miserably, so even if you're savvy with repairing small electronics, the general suggestion is to get a pre-made digitizer & LCD, it is without a doubt well worth the price difference of a Digitizer or LCD standalone.
Thank you for taking the time to check this out, I hope someone may find it useful and save them from a bit of misery.
you are fantastic! i will try to replace the screen in next days...your guide is the best!
very thanks
excume friends, but i'm from venezuela...... i buy a HTC TOUCH HD in miami, the february 2009, ,i phone present this problem, the LCD work fine, but the touch no responding, anybody know where can buy it...... i donĀ“t know how call the replace..... digitalizer, LCD.... how???
Thanks and excuse me by me bad english........ i know, soooo bad.....
Believe me it's almost imposible to replace just digitizer.
I have similar problem few weeks ago, and I buy pre-made LCD+Digitizer and replace it without any problem. I bought my from ebay. UK reseler. 65 euro. I heard that you can find it for lower price but I was searching on ebay.de so maybe on US ebay you can find for less money.
Don't bother to replace just digitizer, just to go 40$ less. Sometimes is batter to give 40$ more but to do job without any problems. (PS It's very, very hard to detach factory attached LCD from frame without braking it!)
Good luck!
Thank you so much, look for us on ebay or on amazon.com to see them .... any questions do not hesitate to do that around here ...... thanks again

... What do you think? Does this serve me?
my baclstone started acting funny with screen alignment getting messed up and than it completely stopped responding...
even the touch sensitive hardware buttons donot work no more...i have hard reset many times did task 29. i have changed different roms and went back to stock rom but screen doesnt respond at all... not even the backlight turn on to full brightness when screen is tapped?
anyone have any idea whats broken lcd or digitizer or both... or maybe something else.... and there is no official htc repair shop so i probably gotta fix it on my own
Got Touch HD from someone I know.
He has scratches on the fone screen, so he decided to DIY by replacing the screen, he did not manage to screw everything together so he gave it to me...
I have tried to follow instructions both here and another thread which points me to videos that I can watch...
The problem is that I have black screen, I can hear the sound when turned on. Just no life on screen.
The screen was super glued on so there was no reponsibility of removing and check if eveything OK.
Could it be that the screen defect?
Have google but found no info on how to attach screen to the fone !!!
There was just one ribbon cable, I believe from the screen to the main borad and it is attached to the main board....
OK
Have had some free time over the weekend, disassembled the phone and found that 1 of the fles connectors was loose. Reconnected and all was perfect...
Now I have a fully working phone
Thanks for the guide....
Don't try to replace only the digitizer...i suggest to disassembly the phone first to buy the digitizer.. to see how much is hard to detach to lcd without broke lcd! if you can detach you can buy only digitizer!
i bought the digitizer but i broked my lcd to try to change...with Lcd+touchscreen's block I ve changed in 10 minutes and it is perfect!
Glad to see this has helped others.
My main intention was to cover the steps missed by the not so comprehensive service manual, if it was more comprehensive i probably wouldn't have started this thread to show how I repaired mine. was quite a few too many important steps missing really. (re-adding the camera, etcetera)
Hi all,
I just replaced the lcd screen of my blackstone and got a new touch screen, I put all together but the touch screen seems to be dead. Is there anything I should check? you always talk of touch panel and digitizer like two different layer, does this mean that I should have 3 different pieces (LCD - digitizer?!? - plastic touch panel)? Because I only have two, the LCD and the "glass" with an outgoing flat cable. In the case I am not missing anything, should the touch panel work even if not in contact with the screen ?
If you got one pre-assembled (which we call LCD + digitizer), it would actually just be one whole piece.
If you have two pieces, then you have a LCD screen (the glass one AFAIK) and a plastic layer (the digitizer)
My replacement part came in as one, and in the OP I disassemble, and remove it and place the new on in the old ones spot.
Sounds to me like youve gotten the parts not pre-assembled by the manufacturer, unfortunately its common for non- pre assembled ones to not make contact to eachother properly when you assemble it, some people reported being able to do it, and others from what i've read found either partial or no touch capability, but it would likely be the digitizer contacts are not touching the LCD contacts (kind of a ribbon on the plastic piece)
It maybe worth just getting a pre-assembled replacement. if youve already used the current one and cannot fix it.
No it's not preassembled but you probably solved my problem. you basically say the touch panel and the LCD MUST be in touch in a specific point to close some contact (maybe the lower LCD ribbon must touch the lower part of the touch panel?)!! If you confirm that than probably that is my fault. I've seen some videos on youtube where the touch panel works even if it's away from the LCD but it was not a blackstone and probably not a resistive touch panel.
Please confirm I got it right, you probably saved my blackstone.
as far as i know, the digitizer will have some kind of ribbon, on the LCD theres contacts or a socket for that ribbon, you can see (poorly) in the pictures I took, where I show the LCD and digitizer and a layer (digitizer and face place layers) of torn apart.
I looked around my room for my old damaged screen but unfortunately I can't find it I think I may have disposed of it.
lucky, ebay type sites do have some pictures of the digitizer and its ribbon as you can see in this picture - link (I googled this and found it here
that ribbon would likely attach to the lcd panel, I'm quite sure if they aren't making proper contact the touch won't work.
But, having said that, before I made this thread, while reading about others who did a repair without a pre-assembled part, they mentioned that the digitizer part contained many tiny bubble like resistive cells in the digitizer layers, its imperative you don't damage the any of these touch cell things, because if they somehow get damaged, even if you get the digitizer ribbon to make proper contact with the LCD board/slot/contact (which ever its supposed to plug into), if those tiny cell break in the digitizer the touch wont work (could be partial, or could be overall interoperability) and if that happened, it would be a circumstance where you'd need to source another digitizer.
this is more or less an elaboration on my prior post I think.
What I can say for sure is before I fixed mine, after some searching around on these forums and on others, I found that most of those who did not get the digitizer, face plate and lcd factory pre-assembled did not fix their handset (only a minority did), they either ran into a problem with the digitizer making contact with the lcd panel, or they somehow damaged the digitizer resistive cells.
Also, since I did do mine with a pre-assembled part, I cannot say absolutely that the resistive cells will be between the faceplate layer and the second layer of the digitizer replacement part (like you see in my pictures, I ended up with 3 layers) it could be that the resistive cells are exposed on the back of the last layer and need to sit against the lcd, once again though, I'm not sure about it because I did opt for the more expensive easier choice to fix mine up.
Hope you get it all working smog
No way, tried to push lcd and digitizer together without any result. I don't believe there is something that can be broken on the back of digitizer (Resistive cells???) but I hope you are right, I am waiting for a housing I bought from HK it's complete with a new digitizer ... we'll see
Thanks a lot
Hello, great guide but I am still having a problem and I wonder if it's with what I bought; Off ebay I got the plastic and the glass attached to each other as I assumed thats all I needed because my lcd works fine. So I connected it all up and it only slightly works, where you touch the screen is actually showing up as quite a bit below (depends where - top left corner works fine but if you click the center of the screen the phone thinks you're clicking at the bottom).. I have tried calibration with no luck.. Any help/suggestions greatly appreciated.
Thanks
Afraid that theres not a lot you can do, if you havent fully reassembled it yet you could try reapplying the digitizer layer but I think that even trying that could make it worse then it is.
Like i said a few times, I wouldn't try replacing the digitizer on its own, I read up on it before repairing mine and concluded it was too much risk or trouble and just got an all in one lcd + digitizer which I used in the guide.
anyway these phones are quite old now, its hard to justify spending on an LCD and digitizer to fix one up.
you need to decide if thats worth it to you or not.
Infact, my blackstone has Newton rings again on the replacement screen, im not certain what squashed against it hard enough to cause them but it happened recently, the digitizer on mine is still working even with the newton ring damage so Im not planning on replacing the screen again.
Okay thank you very much for your help,
Are they still good phones though? I have a nokia 5800 from around the same time and i'm bored of it now but can't afford a new one so i bought this one really cheap as broken and was just going to fix it.. Or is it not really that much better?
Thanks again for your answer
they're considerably faster then nokias usually, i had the 6600, 6260, 9300i and they were all considerably slower ARM processors.
but It will all come down to what OS you run on it, if you do put a WinMo 6.5 rom on it it will be slow to the degree where its unusable. but if you use a 6.1 rom on it then it will never suffer from slow downs (unless the rom is hybrid 6.1 with 6.5 stuff like the one i use).
It also can do heaps of stuff the nokia can't, assuming your nokia is a series 60 or similar.
the Os can do tethering and heaps of other neat things, winmo also has got a fair range of apps, tho dated now, the variety is nice and gives you functionality, you could obtain a lot of this on a nokia symbian phone but winmo (based on wince) is just even better then symbian.
I think it all comes down to how much it will cost you to fix, I have a better phone so i cant justify spending over 50 dollars on fixing a slower older one, but to someone who doesnt have a better phone it may be quite viable to spend that to benefit the improvement over their current worse phone.
ideally, I would say just skip over it, its not truely that fast, you need at least a gigahertz phone to be fast. a HD2 or something, if you can get one like that quite cheap and in good condition, it would be worth more then spending a bit on the blackstone (touch HD).
just my opinion though
I would repair my blackstone again because i get use out of it each time its healthy even though I have something better its still handy to have, i love the audio output on it over my htc desire, but i wouldn't be spending the amount i spent on another repair screen like it did back when it was the best potential phone i could have had at the time.

Fun times repairing my G1

Okay, so I had this G1 for about a month now, works fine, rooting was a blast, but I wanted to get rid of the cracked digitizer glass. So the part comes in the mail... I read and followed the take-apart tutorials to the letter, install it, put it back together, and what's this???
The screen is dark with no display, I slide out the keyboard and I get a display but no back-lighting. I wait for the thing to get to the home screen and I am not getting any touch-screen action. Any ideas? It is safe to assume the digitizer may be dead but what's the deal with the darkness?
Prior to installing the screen I had the back-light issues and I thought "maybe one of the flex cables are loose" but now I am dead in the water. Any info anyone would have about this would be helpful
Thanks

That sounds like the right thought. Clearly, something isn't connected properly.
As i see, there are three variants (from good to bad):
1.) You`ve connected some cable badly, or, for example, you`ve didn`t put down the black blocking panel on some of connectors where it is. As for me, i`ve additionally put some scotch upon any connector i was attaching - it works.
2.) Some cable went bad due to inaccurate handling. When i was doing the same thing (replacing G1 digitizer) - it was stated in manual, tha flex cables, especialy black ones, connecting mainboard with LCD&touch block - can be easily torn. You should examine then carefully - electrical tester would be a nice idea.
3.) You`ve spoiled some chip on the board with static electricity on your fingers. It is really rare - but really bad variant.
Hehe turns out that the flex cable was already fried before working on it, thanks to a great friend I received a new flex cable and was incredibly surgical putting all those cables back in, but I did it. Back up and running @ 100% muahahaha!
So how do I cook for this device?
