[HORRBLE!] Software breaks after physical fall!?

So I was shopping for pants today, but I forgot I had my Desire in my pocket (front right one, if you want to know).
So, my phone fell on the ground and the battery and the cover flew off.
I quickly bought my pants and rushed out to see the damage...
IT WAS HORRIBLE!
The thing didn't want to boot, all it did was flash the red and green LED...
I (somehow) managed to get into bootloader to see the damage...
That was ALSO HORRIBLE!
The recovery kept restarting (4EXT, the loading screen that says 'preparing boot') and all I could do was take out the battery...
Thank god, Fastboot worked, so as soon as I came home I started running the RUU (from fastboot)...
Again, HORRIBLE!
when the RUU said the phone was gonna reboot into bootloader, it DIDN'T - the LEDs just kept flashing!
So I pressed power+vol- and that did the trick, but after the RUU finished ... again, flashy LEDs...
So, is this a software or hardware issue, and how to fix it (other than going to a guy and pay him to do it, which I'll do anyway if you people (god, no!) don't know the answer...)
I think I'll go to Fastboot next and clear all storage...
EDIT: Held the power button for a few secs, and the HTC boot logo shows up...
EDIT2: THE BOOTANIMATION!!! FINALLY!!!
Still, I'd like to know what the issue was, since it seems like it'll work normally from here on...?

Seems like all I've damaged are the LEDs and the camera Flash (the camera says it's too cold to use flash...)
I'll heat up the battery and report again
P.S.
Sorry for the double post... My PC is laggy today...
EDIT: Can't boot into 4EXT, no matter what... I tried CWM and it worked fine, but 4EXT won't...
And just today, I bought a new SDcard so I'd have more space and speed so I could partition it...
EDIT2: Also, the battery doesn't want to fill up... The second I take the charger out, it shuts down... Looks like I'm in need of a new battery... (curse my pants' pockets for being so big!)

It won't be bad to disassemble your phone and see if some connector disconnected.

How do I do that...? Is there like a hardware manual somewhere...? Because I'll need to know what screwdrivers I have to buy (I'm all out anyways...)
Yeah, it's probably the connector, since I can hear something shaking when I shake the phone (or it's something broken... hope it's the first thing)
Otherwise, there's a little power button glitch when turning the thing on... The LEDs flash and I can only boot if I hold the vol- button (can't do anything, not even bootloader!)
P.S.
I was just waiting when you'd reply (oh, Great one!)

Youtube is a miracle...
You'll need TORX screewdriver (star shape 6 angles), a small one.

Took my phone apart, saw the drivers I need... Just gotta wait till morning so BauHaus opens up...
I saw the tut on how to replace the screen, so that will help... Other solutions WILL be YouTube, since I don't understand anything from those pictures (but the text part of the guide is great)
I found another glitch: The LEDs flash if charging even if the battery is 60 meters away... I don't believe that's a sign of a disconnected connector... Hope it is
EDIT: Installed SetCPU, and my battery has been at 0% for the last 12 hours (without charging)... And the phone works... It just won't turn on sometimes...
Picking up those screwdrivers at about 6 pm

Just one question:
Is it possible for a connector to break? And if so, if one is broken in my phone, is it possible to replace it...? (haven't gotten the screwdrivers yet...)
If not, do I have to replace the whole cable, whole motherboard or only the component of the connector...? Or even the whole phone...?

I just popped it open... Now what? I disconnected and connected every single connector, reassembled it and the LEDs still glitch... And the phone won't go beyond the boot logo...
Could it be the battery? I saw a new scratch today, could I've damaged the battery and that is what's wrong...?
EDIT: Disassembled it again, looking for anything unusual (note that I don't have a single clue about what I'm looking for...)
Looks like I'm leaving the Android phone world... for the next 4-6 years... :'( Good old Nokia, I'm glad I didn't throw you away...

And it appears I'm yet again talking to myself...
Anyways, I'm taking the phone to a check to a repair shop, so I'll know what's wrong...
EDIT: The guy in the shop said a check is free, so I'm just gonna chill and play Minecraft for the next few days until he calls

Meh... The guy at the store checked it (FINALLY!) and he said the motherboard was dead...
And that costs 200€ to repair...
Anyways, I went to another shop and got me an Xperia S...
Goodbye, developer phone

wow 200 for mobo, u could get a good second hand desire that aint pvt1 for 100 lol. ah well hope u get better luck with ur new phone

I bought my Desire a few months ago, in June, for 120€ (PVT3). It was used, but it was the only used Desire in town... (seriously, I was the only person with a HTC Desire in my town (with 200k people!))
Ah well...
Guess I'll be the only owner of a Xperia S in 4 years

Dead Desire Z? Need help...

Hello there folks. I've had my Desire Z for 2 years and it always worked great, it is rooted with S-OFF, HBOOT and all, I was running Andromadus Mimicry 1.5.0 ROM. It was working flawlessly as usual, but yesterday I picked it up and it was turned off, I figured it needed a charge so I connected it to the charger, but to my surprise I didn't get the usual orange led, as a matter of fact I got nothing. I waited a few minutes but still nothing. I tried to connect it to the PC but again, nothing. So far I tried different cables, different batteries, chargers, tried the car charger, but nothing seems to work. I tried using ADB to run a Fastboot command but that also didn't work, it hangs forever on <waiting for device>, and ADB doesn't detect it. It really seems absolutely dead. It doesn't show any sign of life, no light, no vibration, NOTHING. Has anyone ever seen something similar? What can be done to resurrect it? I didn't do anything different, it was all of the sudden. I appreciate any help, thank you!

Once I saw a problem like yours and we figured it out that the problems is because of the
eMMC-boot

chip of the device's hardware. Once we replaced the chip ( I dont know if you can do this. i suggest you to buy a new Vision mainboard ) the device started to wark as fine as it used to be

Hey, thanks for the reply! While researching what could be the problem I came across this eMMC issue, I was hoping that wouldn't be the case, but unless someone else sheds a new light on the subject I guess that's probably it. I even looked for a new eMMC chip or Vision mainboard, but couldn't find them anywhere. I guess with the price of a brand new Desire Z at U$90 - 120 nowadays it wouldn't be worth it anyway, I might as well just buy another one, as a matter of fact I probably will, as I love this model so much, but I really wanted to save the one I already have, that way I would have a spare.

You can buy a new Desire Z and keep the old one as a restore device who knows maybe some day you gonna need a touchscreen or a LCD panel or both?
Just keep it

Yeah, I thought about that too, I'll probably need it sooner or later, I had to exchange the led flash once. Who knows, maybe the eMMC could be fixed with JTAG, but that RIFFBox is so expensive. If it weren't I would certainly get one as it's useful for all kinds of phones. Hey, thanks for the reply again, I really appreciate the input. I hope the thread goes on and people keep giving new ideas.

Chances are it isn't an emmc issue, as the emmc issue just stops the emmc from being written to, so the phone will show some signs of life.
It will be some sort of hardware issue though, seeing as it's not doing anything at all.

Thank you very much for the info Nipqer. Is there a way I can tell what kind of hardware issue happened? It really doesn't show any signs of life, no lights, no vibration, no orange led while charging, nothing. Aside from that the phone looks brand new as it has always been well taken care of. Is there something I can do or try out? Thank you.

Did you try a new battery? Or an external charger? It is possible battery is fried or USB port is dead, a new battery and external charger could help figure that out.
Also you can try taking out the battery, plug into PC via USB while holding down both volume buttons, phone should vibrate a bunch

Yup, I got 2 extra batteries besides the stock one that came with it, one of them is a Mugen Power Battey and the other is another original just the same as the stock, tried many different chargers, 4 other wall chargers, different cables, car charger, etc. Doesn't seem to be the problem. Tried to do as you said about taking the battery out and plugging into the PC via USB, still nothing, not even holding both volume buttons down or any other buttons... Hell, I even tried holding ALL of them. Still no deal.

Sorry to say but my guess is logicboard is shot, good news is a new dz/g2 is cheap nowadays

Sadly seems like it. Well, I guess I'll get another Desire Z and store this one for parts and scraps. =/ I still wish someone would appear with a fix for this.

[Q] htc one x problems after screen repair

hi, have searched and searched on the forum but no real answer to my problem.
i dropped my htc one x and the glass cracked, so i sent it away to a supposed reputable firm (i didnt realise htc repaired phones aswell otherwise i would have sent it there)
anyway the lcd display and brightness worked perfectly, the company have replaced the screen and now the backlight no longer works and flickers when touched or cpu is being used.
they have said it is the display IC, and coil etc,
they say that this was caused by the phone being dropped, and not by them and they have charged me (they take payment before sending phone back), they initially took the phone back, and 3 weeks later they have decided to wash there hands of it, have put the phone back together shodily tell me i have to put up with the phone as it is, and refuse me a refund.
they acknowledge that the ic was fine before they took it apart, but blame it on the nature of the phone design as to why it now doesn't work.
i would post link to another forum explainingg the possible issue (has no explanation of cause though) and pics of the phone has been returned to me, but i can't because im a noob

Basicly the question is,
Who is at fault?
And how could the ic get shorted out,

The backlight flickering is likely to be poor installation of the new screen.
Again this is an old example I'm referring to here. I used to replace the screens on the Nokia n95 quite regularly.
You get the screen assembly and the ribbon cable which attached to the motherboard.
If the ribbon cable was not seated 100% perfectly I would get the exact same symptoms you are describing.
No backlight. Pressing down on the screen would either get it to flicker or come on for a while.
It shows a poor connection. I took the screen back out and repositioned the cable back in. Reassembled and then it was fine after

Hi mate did you managed to get this sorted I am having the exact trouble same issue with a company call Elite Phones and Computers.
They are saying that the IC shorted out and the only repair would have to be a replacement board.

[Q] [HELP] Blinking orange light. Won't boot.

My G2 might be dead. It won't boot up. When I press the power button it vibrates three times then blinks an orange light on and off continuously. The only way to stop it is to remove the battery. When I hold volume down and power it vibrates about five times then has a green light for a little bit. Either way nothing shows up on the screen. It was doing this same thing a few weeks ago, I messed with it a little bit and it worked fine. Adb will recognize the phone only if it has the blinking orange light. I have tried charging it, of course. When charging it has a solid orange light until full, then it's green; just like normal. I wasn't doing anything unusual when it started (flashing a rom, messing with system files, etc.) it just happened out of nowhere. My rom is LewaOS. The first time it happened I think I was using JoyOS. I don't think it is a faulty battery, because I tried swapping batteries with my brother's MyTouch 3G Slide and the issue was the same. (I know they don't have the same battery, but I held the battery in at an angle so the contacts would meet). Has this happened to anyone else? I would really like to get this figured out, because I don't have enough money for a new phone and the old school Nokia I am using for the time being is sort of a pain.

Does this mean it is bricked?

What happens when you plug it in to PC? Does windows auto search for a driver called qusbdownload or something like that?
Sent from my Nexus 4 using Tapatalk 2

If it is "on" when I plug it in Windows tries a driver called Qualcomm Technologies something or other then says the driver failed.

Then chances are its bricked, this means the phone is trying to get into an HTC download mode that no one has gotten to work with the vision to the best of my knowledge. There has been work done on other phones (the debricking project) that makes use of this mode to unbrick your phone, but nothing for this phone
You can try to leave out the battery for a week (fully charge battery first) and the test it, some say this works and it did work for me on a similar phone in a similar circumstance or you could get someone to JTAG it back to life.
Also I have read that some people have been able to open the phone and clean it thoroughly, reassemble and then it works. I've opened these phones many times and don't know what components need cleaning but you can enter this mode holding the volume down button while plugging phone into PC, so maybe the volume rocker or USB needs cleaning
Just some thoughts, best of luck to you!

Even though you're basically informing me that I have a bricked phone, I'll hit the thanks button for your knowledge. I will try some of what you said, then probably commence the search for a phone I can afford.

haha, i dont require thanks, i help for the sake of helping! but thanks!
HERE IS A LINK to more info about the vision, including brick advice and teardowns of your phone.
If your looking for a cheap fix you can often find a used cracked screen broken g2 on ebay for under 40$ and its easy to swap logicboards. if you really want a qwerty phone there are few to choose from and this is still one of the top choices.
I own many qwertys, htc g1, g2, mytouch 4g slide, samsung sidekick 4g, just bought a samsung relay and really my favorite to this day is still the htc vision.
my advice if you cant get yours working, consider swapping logicboards, take about 10 minuets and LOOK HERE cant promise anything of course but sounds like a perfect phone to swap logicboards and only costs 24$
best of luck!

Goodbye
I guess this is my farewell to the G2 and Desire Z forums. You guys have been great. I thought about buying a Vision with good internals and swapping them, but in the end I decided it was time to try something different. I've had this phone for a while. Ideally, the HTC One (M7) would be the successor of my G2, but it just doesn't work with my tiny budget. My second choice would have been a HD2, but, again, I don't have enough money (that's how small the budget is). Today I ordered a Motorola Milestone 3 for $49 on ebay, so when it arrives I'll hopefully be able to get my SIM to work in it. I thought I would never buy a non-HTC phone again (never a Samsung, not even once). Oh, well. Who know, maybe someday my desolate G2 will get jealous of the Milestone and decide to boot up again.

Black (not working) screen after drop.

Hello comunity
I bought one nexus 2013 wifi... (Second hand) and I am planning to mount it in my car...
well ... i just started preparing the software ...rooting, unlock bootloader and so on ...
then accidently I dropped it on the floor :/
After this the screen is black. It is OK - it is not brocken but is not working at all...
The computer recognizes the Nexus (I can see it from Device menagment in my computer).
Then I opened the Nexus..
Reconnected the battery... and trying to hold the power button for 60 sec...
again nothing worked and the screen is still dead.
Is it possible this to be a problem?
https://goo.gl/photos/k4EYBvWvQynab3v16
seem it is not OK... (There is a black line on the cable ... may be it is a missing part >)
If i buy one of this cables and change it may be the problem would be fixed??
Tnx and Happy new year

Yes, that part has been stripped. Can't tell if that causes the problem, but I'm almost certain it was not caused by the drop since that part was locked inside the connector, unless it had already fallen out when you opened the thing. Where you ripped it when removing, you might want to look inside the connector to make sure the loose bit doesn't remain in there as it could short. I take it you're not in the US. Otherwise, I could mail you an extra cable I have. Good luck with your repair.

Disconnecting the cable caused your issue for sure, be careful before you tinker with devices.

This cable is OK unless you damaged it during disassembly. The most likely failure is the screen. Have a look at it with a lamp at an angle to check for any cracks.
Did you earlier manage to install TWRP? If so boot to recovery and check with ADB file system access.

Well..
Tnx to all of you.
The tablet is working again.
The problem was this cable.
I ordered a new one.
I really couldnt undartand how just one drop can be the reason for damaging the cable.
