Cingular 8525 won't turn on

I have a Cingular 8525 and it just recently turned off and will not turn back on. I've removed both the battery and the sim and let it sit for a while, put them back in and it still won't turn on. It was cabled to my laptop at the time. No indicator lights at the top turn on at all, even with the wall charger/adapter plugged into it. I've already requested a warranty replacement from Cingular, but apparently they are only sending the phone and not the battery. The person I spoke with said I could go to a Cingular corporate store and have them order me a new battery (none of them in my area have the battery in stock).
Any suggestions? Can someone confirm that the phone will turn on with the battery out and the phone plugged into the wall charger? Can somebody turn off their phone and plug it into the adapter with the phone off and tell me if any lights are lit? Any help would be greatly appreciated. Thanks.

Hi
With no battery in the phone will not operate at all. There should be a RED Led lit up to indicate that the device is failing to charge.
Mike

I know this thread is old, but hopefully someone can help. My 8525 stopped working as of recently. When I plug it up to the charger, there is a red LED..does this mean my battery is junk? or the phone

if there's no battery and you connect the charger, a red light will show......so most likely it would be your battery that's junk. check your battery connections first.

Same problem!
The phone was connected to my computer and was in the middle of replying to a text message when the phone rang. When I went to answer the phone froze and wouldn't respond. I hit the soft rest button and it stayed frozen. I took the battery out and then I got nothing. Won't turn back on. Any suggestions?
Thanks in advance for your help.

If you get no LEDs showing when you connect the charger, then the fuze may be blown.

Fixed
I did a search for the fuse placement on the 8525 and found several screen shoots. I used a pair of tweezers to bridge the gap to see if it was the fuse or not. It worked!!
Replacing a fuse this size on a MB that small is almost impossible for the average person. What I did was place a small amount of solder across the fuse. Everything looks good so far. Of course I will now place the phone inside a sauce pan and leave it on top of the stove top to recharge until I find one on eBay with a broken LCD!
Thanks for the heads up. I'm was hoping for a "normal" fix for this problem. I very grateful for this site and all the users who lend a helping hand.
Cheers, David

My 8525 (HTC Hermes 100) just quit working
Last night I had no problems used the phone while out...got home and my phone just wouldn't respond. No soft reset, no taking out the battery, no charging via wall or by computer worked. No light display to indicate it was charging, or battery was low I tried all these possibilities.
This phone has never touched the ground. (I just got it 2 wks. ago. Its my second HTC Hermes, never had a problem with the other.) the power was at 50 percent so it wasn't dead even...
The phone is unlocked, I don't use ATT, even though this phone is in immaculate condition, it is used, I bought it from someone else who barely used it, so no warranty.
I have taken my other Hermes apart to fix the ribbon cable and screen...I would hate to have to do the same with this phone it still has the void stickers in place.
Bleh, look I love this phone, and if anyone has any suggestions I welcome them as I know this thread is old. I would hate to junk a phone that I can just fix...

I believe u need a charger that could charge the battery outside of phone then when finished put back in battery and see if it turns on u may need a multimeter to test batterys DC volts to see if is below 3.2 volts

Okay - first sorry for opening this deadish thread. But figured better than opening up a new one.
My phone is doing the same thing - it just quit working randomly. Went online to get an address to our next destination. Got there, and picked up phone to make a call - and it wont turn on.
i noticed a capacitor looking thing near the charger that looks like it's cracked or messed up.
Can Mike or someone look at theirs and let me know if it looks similar? Thanks to XDA, this 5 year old phone still feels brand new - and I really haven't seen a need to replace it for at least another year.
Any help, appreciated.

Well aside from the fact you haven't been dusting your motherboard for a while, the component looks OK - here is a picture of mine, see no dust:​

(JUST IN CASE anyone gets confused (get it haha) that is not a picture of the fuse in the picture shown above)​
Assuming you have no LEDs showing even when the charger is plugged in, then it is very likely to be the fuse:
http://www.mikechannon.net/PDF Manuals/Hermes Fuse Location.pdf​
Not that I recommend the old tweezer trick mentioned in a post above! - but it might be worth trying. Or soldering across the fuse. (Neither of these things is at all professional, but I'm old enough to remember putting paperclips in fuse holders as a strictly temporary measure you understand​
If you have any LEDs showing then it is not the fuse.​

I say if you can find someone to take a look at it, you may be able to fix the issue. For me it was as easy as seeing if it was the battery vs. the usb connector vs. even the battery indication LED at the top the phone.
Issue was a mix of the battery and the connector. Fixed and though I have an iPhone my HERMES will always be number 1!

Thanks Mike! You know - I was going to post "please don't mind the dust" then i figured, everyone else's gotta look like that. i guess not, eh?
anyhow i realized that that thing wasn't the fuse - from finding this thread before I posted, I was actually able to get to the fuse. My eyes caught that funky looking thing and said, hey this doesn't look right. So I figured it might be the issue (okay, i hoped it's the issue, because even with my fat sausage fingers, I can probably try swap that out).
I will try the ole tweezer trick to see if it will work. For now I'm in an BJ II - no touch screen and no WinMo (no matter how much we've grown around here, i still like the WinMo interface).

yeah - I can't drop the hermes for an iphone... thanks to these guys in XDA, my 5 year old phone feels brand new ( i just put 6.5 on not too long ago) and was loving it. I will never buy a non-Xda supported device, ever
btw, how much did you fix run you?

BTW Mike have you ever insert tweazer in the EXTusb port?
All the USB cables have some kind of shortcircuit so i asume that the pines are just to low and i need to rise them a lil... do you think it can be done? thans a lot

Not tweezers, but I have seen reports that they can be tweaked with a pin. However, you'll need a magnifying glas or preferrably a watchmakers Loupe. I'm lucky, I do watch repairs as a hobby so I have a Loupe and it makes life much easier!
Pins in the USB port do get bent easily and can cross each other.

help!
Last night i was surfing the net on the handst htc tytn, i in the meantime connected to my laptop thru usb n transfering mp3 songs, while doing so the handst hangs, i removed the battery, then when i tried to restart it boots up till microsoft corporation and doesnt go beynd that, no hard reset helps am using windows mobile 6.5 titanium hd. plz help

OK so I think i was able to confirm that it WAS infact the fuse. Tweezing it with my giant tweezer was difficult, but did work (I saw the RED led light come on).
Now - the question is what do I do? I am not sure I have the skill to solder this tiny thing w.o. getting solder ALL over the components around there. BUT at the same time, to me the device is dead, I'll only be putting the nails on the coffin if I mess it up.
Does anyone know if a regular ole cell phone shop can fix this? Or am I going to need to spend more than the device's street value to get it fixed ala the ole cheaper to replace than to fix mantra?
Advice, appreciated

Personally, put the repair money towards a new phone... It will probably be expensive..
Sorry, but as much as I loved the Hermes, its getting just a bit long in the tooth... Newer devices have more ram, and more little things, like GPS and so forth..
Though it was a good Phone, my Hermes has been retired for a younger faster model, aren't we all at some point...

Please Help! Black screen but LCD has backlight!

Well guys this is what happened:
1. My wife got mad with me and broke my lovely trinity. In fact only touch screen was broken, lcd still works.
2. So I bought a new one on ebay (lcd+touch), so much more cheaper!
3. I replaced the broken one for the new one and everything was fine, I got my trinity back
4. Anyway I had to disassamble it all again because lcd was not placed conveniently, I've done it several times until I got it perfect but when I power-on there was no image on LCD, just a black screen with backlight.
5. I thought it could be a damage in flex cable, but older lcd leads me to the same result.
Any idea?

hello friend how the things going!!??!

Can't find a reason for it! Broken flex or chipset damage? I'm not in the mood to buy a new one to check it!...

hi, it's has appening the same thing to me!!! but i solve it!!!! how? my problem was in the connection of the LCT to the motherboard! I just have put a small paper in it between the cover to make some pressure on it and then the LCD work perfectly!
if you need some more help, tell me something and i will take some picture of it!!!
great rom's!!!

Boy I just bought a new LCD on ebay thinking i'd get my problem solved!
So we'll have to wait someone help us...

Great! I got my trinity working now with my brand new lcd, but it's kinda unstable i wonder if could be keypad flex cable that is broken as i read somewhere that a broken cable could cause other issues...
NOW SOLVED: I unpluged keypad flex and removed the whole board now it works perfectly (no keypad of course, but i'll buy a new one )

happy for you!!!!
hope you can release a new PTG rom for trinity!!!!
greetings

Thanx!!!!
Thanks vimafeje!!! you are great!!!! i thought my problem was software!!! i tried all kind of stuff,change roms, radios, format with mtty, unbrick..and always got that black screen!!! almost tried everything!!and i luckily found this thread... your solution was mine!!!
before reading your thread i used to make some pressure on the down right side of the battery...and it was working a couple of minutes because when pressing on battery i was pressing under screen !!!
anyway......i'll try to disassemble it to fix it.....
i think my problem came from one of my trinity's fall !!!
take good care!!

hello,
its look like you are having a connection problem with the flat cable to connect the screen to the motherboard. making some pressure in the side of the trinity, like in the picture posted some post ago qill prove that.
so, have you try to dismantle them?
try it, and make shure the flat cable is in place, try to turn on the phone while he is dismantle, and if the screen is not working, try to touch this flat cable.
i solve mine by luck, i have dismantle mine more than 50 times!!!!! but now, it's working wonderfull!!!!
good luck!!!
try it,

The problem is the flex cable connection of the display or keypad to the motherboard.
Check if the display flexcable is well aligned and properly inserted into the motherboard slot.
Place a piece of paper or other soft material on the two connectors (display/ keypad) to improve the pressure from the back cover in these components.

Hi guys ... i tried to dismentle it many times
the main problem coming form the motherboard itself ..as i touched the lcd flat cable and nothing happend still black screenn,,but if i twist the main board it works fine and quickly
thank for replying
hope we find a solution anyway,,i nneed my trinity so much

try to assemble and disassemble it until it works, and try to put litle piece of paper to make some pressure in the flat cable to the motherboard/display.

Thank you for your fast reply,,,, i really appreciate it
i am working on it now ,,, i try to find where to put the paper piece and i will tell you the result soon ,,,, thank you
Jimmy

i have the same problem 3 weeks ago, if u r in Shanghai China. I bet u can 100% fixed. I hv send to repair house and they tried to fix the flex cable but no luck. Change the touch screen same issue happen. and when the Samsung CPU is depressed. It boots up all right. So... the root cause is the CPU BGA balls suspected crack. So this guy just removed it reball it and place back.. Wallah!... IT WORKS！！！。。。。 My Trinity was dropped before black screen... hope this help!.. My advice is if you r not good in rework skill,don't do it. Get the expert help!... it cost me RMB400... :-(

Hi guys ,, i tried to place a piece of paper under the flat cable ,,but no luck to boot normally,,, i think the problem like Gooki said ,on the one of the chips placed under the LCD connector,,,,, i hope i can find someone can help me in egypt ....
could u send me the name and the address in china pls for repairing ,,,, maybe i can send mine to be repaird i have 2 trinitys should be repaired ... thnaks

here to put the paper:

What can I do with a screenless device

Beginning of the year my younger brother gave me his replaced HTC Touch from Telus (which I believe is the Vogue - correct me if I'm wrong). I used it for all of 2 weeks before it cracked in my pocket (huge rage moment).
I've got a Sapphire now, so it's cool, but I just found this busted phone. I still boots and I can hear sounds coming from it, but the screen is still toast (of course).
So, is there anything cool or fun or useful I can do with it? I'm not afraid of getting dirty or technical with it.
Here's a picture:

get a new screen?

Is it worth the cost? And where do I get one?
(I post before googling, mostly to get more responses, but off I go...)

I found a couple of replacement parts. I guess the screen for the Vogue and Elf are the same.
Now theres two things here:
OEM LCD Screen Display $50 US
https://www.gsm4world.us/htc-touch-oem-lcd-screen-display-d-01230_238.html
OEM LCD Digitizer/touch screen $20 US
https://www.gsm4world.us/htc-touch-oem-lcd-digitizer-touch-screen-d-01246_238.html
What's the difference? I'm fearful of the second one only being the touch input, and that I'd actually need to replace the screen, which is $50 US (and I'm in Canada - pushes it high enough not to be worth it).
Anyone got a broked model with a working screen they want to send me?
I was hoping I could do something without a screen. Like run a TF2 server or host a file share. (I hope you get the sarcasm)

you could sell it... check ebay for the lcd screen and you might save a little money.

can you access the internal memory using active sync? if you can, you can place a .lnk of any program installed on your phone into the /windows/startup/ folder and have it run automatically on boot. trying to think of a program that would be useful without the screen, coming up with blanks right now.

Not sure, I've never done this before. Perhaps I'll try some of that this weekend. It's not really important for me, just something cool to do.

Screenless Device
interesting.. Lol.. I am in Canada looking for a Touch Vogue Cell (doesn't matter what provider as I am pretty sure they are all the same except for Roms and Wifi. )that I can use for parts.. My Touch sensor died, was hoping to get one that was mostly in tact as I can use the touch sensor and the Casing to fix mine.. If you want to be able to do stuff still you can actually, get ActiveSyc working and use My Mobiler and you can do everything you need to through a computer as well.. Is how I do most of my major stuff like txting and settings etc..
Just some random thoughts..
PM ME if you want to talk

I mostly just want to use it as a phone. I've got a Magic from Rogers that work pays for, but my girlfriend's phone is crap. I've seen screens for these things for about $50 around... I may try to take this apart and see if I can get the screen off. If I can, it may be worth a shot.
Are you saying you'd be interested in taking this shell off my hands? I'm pretty sure it's only the screen because I can turn it on and still here things and clicking and whatnot.

continuing on tatnai's thought....I guess you could set it up to act as an ipod shuffle listen to mp3's without a screen. you could have the music link boot from start and set it to be the only thing that runs and bam you have an mp3 player. Also can be used for a paper weight

Note that taking apart the Vogue is hard without the right equipment. You need a fivesided screwdriver (T5) as well as a plastic prying tool. I recently replaced my digitizer and it was fairly easy with these tools (they came with the new digitizer)
If you want a guide to disasembling the vogue, this is what I used.
http://mikechannon.net/PDF%20Manuals/OSeven%27s%20Disassembly%20Guide%20to%20the%20HTC%20Touch%20-%20Elf%20.pdf

Hey, thanks a lot. I'll keep that guide handy. I don't have a plastic tool, but I should be able to make due with some other things around my tool box.

I personally thought my Vogue is one of the easier phones I've disassembled (had to air it out and redo the LCD flex - water damage). You just need a T5 which you've probably got in a screwdriver set somewhere.
Replacing the display itself would be *very* straightforward - disassemble, remove and reinsert one flex cable and two screws, and reassemble. You aren't going to get much out of it without a display, sadly.
As a note, I had the most trouble putting mine together because of the SD card door on the side - try not to let it fall off during disassembly as it's got some rubber tethers that are mildly tricky to put back. It's not exactly a disaster if it comes off though - it took me maybe 30 seconds. Was frustrating though.

Should be good as a card reader, microSD of course.
Get a big enough microSD card and it's a portable drive...slow and there're cheaper and/or faster alternatives...but something to brag about.

[Q] HELP! LCD screen replacement - Wierd display - (256 colors only?)

Hey friends,
My beloved HD2 (T8585, the international version, running ParanoidAndroid v2.15 Jellybean) had a hard fall yesterday, and the the LCD got cracked on the bottom right. I was left with a fully working touchscreen but no display. So I gave it to a local cell phone repairer to get the LCD+Digitizer/touchscreen replaced. After the LCD+digitizer were replaced, the display has gone complete weird. It looks like I'm dealing with a phone that has 256 colors only. All pictures, camera, apps, live wallpapers etc. are looking horrible now. Of course I did not take the phone back from the repairer and have asked him to fix the display, but I thought it worthwhile to ask the experts out here if they've seen anything like this issue before.
To give you an idea of how things are looking now, I have posted pictures (from the internet) that are in 256 colors only. This is exactly how everything on my phone is showing up after the replacement!

AND this is the best example. On the far right is how I expect a pic to look like, and on the extreme left is how it is looking on my fone now. (please note that all these are pics I got from the internet)
Can someone help me understand what could have gone wrong?
Also, after the replacement all the front keys (except the End-Call key) have stopped working. What's going on guys?...!
The volume buttons are not working too.

If it is not the display itself, looks like the flex cables may not be connected properly to the motherboard- the keys not working strengthens this doubt, though front keys have a separate flex cable, while Vol keys are a part of the main flex. Are you sure this repair guy is capable?

Thanks for your response ph03n!x. Yes, I am seriously doubting this guy's abilities now. Took the phone back from him after replacing the new LCD+digitizer with my broken LCD+Digitizer. The front keys are still not working... only the end-call key is working. BUT the key backlights are not lighting up at all.
I think you may be right about the Flex cable.
The vol keys seem to have a different issue all-together because yesterday (when he first replaced the LCD+Digitizer) I couldnt even 'feel' the key click when I pressed it. Today he claims to have 'repaired' it and the vol up key feels good when I press it but the vol down key has become very hard. Nevertheless, I cannot test anything until the display issue is fixed.
You got any good references in Pune?
P.S. HTC service center had quoted me a bill of INR 8800/- (approx 160US$) while this guy was doing it for INR 3600/- (approx 65USD).
I am getting my refund from this guy tomorrow.

Very rarely comes a query that does not find many answers on this forum. Could this be one such? Only time will tell.
Anyways, I have emailed HTC India customer care asking for the price of a LCD+Digitizer, and I have found this online: http://www.ifixit.com/Guide/Installing+HTC+HD2+PB81120+Screen/5651/1

Ebay has some expensive stuff, plus I cant be sure what they're selling will work on my phone.
What if it turns out to be incompatible like the one I got from this local phone repairer?

Hello,
If you consider yourself experienced enough to open up your phone by yourself, you could actually open it up and look if the LCD flex connector aswell as the Touchflex-Button-connector are connected properly and investigate the status of the volume buttons. This will only require minimal opening of the phone itself....
But please only do it if you think you can do it. If you never opened up electronics before, DONT do it, there are a lot of "traps" to fall in while opening the phone which could cause damage.
In my opinion, the best tutorial is this one. Unfortunately for you, its in German, but I think the pictures should speak for themselves.

You can buy LCD and touchscreen (digitizer) on ebay. There are actually 2 versions, one version, the touchscreen connector is soldered to the lcd display (old), the other version, the touchscreen is connected via a flex cable connector (new and better)
make sure to buy a version which is the same on your phone (if you want to buy LCD and Touch as a bundle, use the connector variant)
You can determine the version you have by going into the bootloader (press and hold volume down and power button), if there is 0x30 you have soldered LCD/Touchscreen, 0x40 or 0x50 is the connector variant
But again, if you dont feel like you can do this and only have little experience in electronics, dont do it. Let someone repair it.
Best regards

Request to mods.
I request the mods to move this thread to the HD2 General section where it may get more visibility (and possibly more responses too).
Thanks in advance.

HTC HD2 256 colors problem - motherboard issue
Hi all. Looks like problem is more complicated. I am working on it for longer time.
I am IT Laptop / Server / PC professional (hardware refurbishment) - mobile phones as a hobby.
I think that your tech guy could do his job properly - I mean labour, like connecting ribbon cable, etc., but..
1st my story: I have got two HTC HD2's. One day digitizer has stopped working on one of them.
(Found that it is a factory fault - every time when you press power button, you crush ribbon cable from digitizer under it actually)
Anyway decided to replace a whole screen with digitizer who bought on ebay. Screen and digitizer was separetly so had to solder them together. After fitting a new screen digitizer works (touch screen), but screen shows 256 colors only! I was checking everything again - like: connections, sockets, ribbon cables. Nothing helps! Decided to try old screen and even a screen from 2nd phone - no success - the same 256 colors only!
Last test was to check new screen (with digitizer soldered by me) in 2nd, good phone - and works fine!
Conclusion: Motherboard in 1st phone is faulty!
Question: Why? New screen/digitizer has damaged the motherboard? If yes - why works on 2nd phone?
Shall I use ESD strap? (never happend to me so far) and again - why works on second phone?
Problem with solder balls due to extra stress during work?
Or maybe I've missed something?
I would be thankful for any professional advice - please write if you really know or at least opened this phone before (no guessing)
I would like to add that I've flashed phone with stock software and no success as well - still 256 colors :/
Thanks.

Not really. I am from Madras, and know a guy here - but even then, when it came to opening up my phone (when it went weird after gathering some moisture inside - another day in the beach!), I decided to do it myself. I followed the instructions from the official HD2 assembly/ disassembly video from here: http://pocketnow.com/hardware-1/official-htc-hd2-disassembly-assembly-training-videos-leaked
Long story short - my phone is not perfect yet. I had to change the keypad for the front keys twice, still they are a bit 'soft', and dont give a solid click - sometime they go all weird, one key will activate the other. And the vol-up is not working, I will have to change the main flex to fix that.
That said, it is pretty straight forward to get your hands on - especially if you have ever opened an electronic item before and have the tools.

I have two HD2, one is whacky (see my reply above) and the other is pristine. I have opened both, and without ESD strap.
Why dont you find the panel manufacturer of this new panel:
Code:
dmesg | grep "Board id"
and see if this color issue is because of difference is manufacturers for the LCD you have gotten newly? We know that HD2 panels comes Acer (AUO) or Sharp - is the after-market panel from either of them, or is there a 'new guy' out there...?!

Guys,
I think my case is kinda different from what both of you described. I took my phone back from this repairer, and gave it to another guy. Surprisingly when he changed the LCD+Digitizer, the colors looked PERFECT! However the digitizer wasnt functioning properly so unfortunately I couldn't get my fone back. Gonna get it back tomorrow.
And on another note, the first repairer damaged the front buttons' panel. I had to replace that as well
Let me revert back with my findings if God-willing all turns out well by this time tomorrow

P580 Power Issues?

Hey all, I recently bought a P580 when I was out in the States with work (I'm back in the UK now). Whilst I was out there it was working fine and when I came back it was working fine when I originally tried it out - I didn't want to use it much as it was supposed to be a gift but wanted to make sure it was all set up and stuff. Second time I tried it, it won't power on. I've tried multiple USB cables, multiple wall plugs and tried charging it on my PC. Nothing seems to get it to power on.
Everytime I connect and disconnect it to my PC I get the audible tone that says a device was connected but that's it. Samsung's Smart switch doesn't recognise it either. Talking to their support, I've tried holding Power + Volume down + home button but that doesn't seem to do anything other than disconnect it from the PC and holding the Power button for more than a minute doesn't seem to do anything either.
I hadn't rooted the device, in fact I'd barely done anything other than install a couple of apps like Facebook, Snapchat and Youtube. Does anyone know what's going on with the device and is there anything I can do? I'd definitely prefer not to send it back to Samsung as they won't accept it in the UK support so I'd have to send it back to the US support.
Anyways, if anyone has any advice it would be GREATLY appreciated. Thank you.

It's not a power but display issue. If you can hear the sound in the background or press volume up and down and you can hear the sound, it mostly has the loose LCD cable.
Search Youtube how to open your tablet, the tool you may need is a guitar pick.
Disconnect the battery first. You only need to disconnect and reconnect the LCD cable. The locking tab is at the top of the connector, lift it gently up 90 degree and be careful, otherwise you might break it. All connectors are unlocked by lifting up from the top 90 degree and they're very easy broken if you're not careful.
Here the LCD cable ( black ) is just slightly below the line on mainboard, you will have a black screen

This one, the LCD cable is fully seated.
This connector is weakly hold the cable, you can pull the cable out while is in locking position. So you need put tapes over the connector and cable to hold it firmly, another one at the center of the battery to prevent if from moving. Battery should be back, otherwise you'll see nothing. Test by plugging your charger and press the HOME button, you should see the battery icon briefly if everything you're done correctly.

Hey, thank you for the reply! I opened up my Tab and it was loose. Unfortunately being a complete beginner I think I f****d it up and ruined the cable - imgur dot com/a/kvP8Z ( I cant post links)
Am I going to have to replace that now as it still doesn't seem to be working.. :/
Other than that I can't see anything else that might be wrong with it whilst it's opened up??
Again, thanks for your help, it's MASSIVELY appreciated!

Speaking from experience, you are in a tight spot now... if you did what I did. I had a Tab S and I opened it up to replace the charging port. Different pieces, but same steps as listed above. I broke the locking tab that holds the cable down. My only recourse was to replace the motherboard. Long story short, it was easier (and not much more expensive) to buy a new tablet. I know this isn't what you want to hear. Sorry about your luck.
HOWEVER, my problem was with supply, my S was old and I couldn't find a new motherboard and the website I found was "out of stock" of used ones priced high. Since you have a fairly new device, you might be able to find a replacement much easier.

I don't think that the locking mechanism is effected, but I scuffed the black LCD cable thing and it's now showing some of the bronze beneath it.. I thought that maybe that was causing it to not just work now that the cable's in the correct position? If it's the case that I've completely ruined the device and that I can't do anything with it, I don't know if I can justify getting a second one in such a short space of time. :/

That's good. You might be able to find a replacement cable or even just put a small piece of electrical tape over the scuffed segment... Depending on how deep the scuff is. There are a lot smarter people on this board that may be able to advise you better.
Just searched "galaxy tab a 10.1 lcd cable" and they are pretty inexpensive. Cheaper than a new tablet! About $2 USD.

Try to tape the LCD cable down to the mainboard, I don't know how bad you damaged it. This LCD cable is not easy to take out as the section connected to LCD is under the frame.
In order to take it out, you have to cut the frame. It's easier than heating up the whole assembly to remove the touchscreen and LCD from the frame. Newbie will most likely damage them in this process.

See Sn0wtek... A much smarter person than me!

This is the proper way to secure LCD cable both SM-T580 and SM-P580, without tape the cable will loose again.
This is another bad design from Samsung, the motherboard has no screw to hold it at the bottom. It can wobble easily, that's reason you need tapes to hold the LCD cable to mainboard , prevent it from moving out of the connector.
