Hello to everyone
I decided to buy a used Moto E with broken screen to replace my screen with the broken one, so I can have a working phone. (If you don't know my history, my E had qshusb_buld). The seller from the eBay is a bit odd and he can't understand the phone's problem.
Anyway, the "new" moto doesn't respond at all. Only a led blinks when I connect it with the usb. It can't be regonised from my pc. The screen remains blank. I tried to replace the battery. NOTHING. I tried to charge the battery from an external source. Nothing
Anyone could help me?
PS: The seller claims that the phone was working fine. The only problem was the screen (lcd broken a bit)
Thanks a lot for your time
That happens only when the device gets hard bricked. Only way is to replace its mother board.
Thanks

Before anyone jumps on me, I've been going through the Wiki and forums extensively, and found just one similar problem. Which wasn't solved...
My HTC TyTN/Hermes 200 won't boot up anymore. It is totally dead. I even can't get it into bootloader mode. Screen stays blank and the LED is off.
Put the (3 months old) battery in another Hermes to test it, and it's at 100% charge.
My Hermes shows a steady red LED when it's plugged into power without the battery in, and no LED at all when the battery is installed. The red LED turns off when the battery is installed while there's power going into the unit.
I've left the battery out for at least an hour, plugged it back in, same results. Like the other guy I tried the "pull power, pull battery, plug in power, plug in battery, reset" trick http://forum.xda-developers.com/showthread.php?t=286469&p=1077622 - to no avail.
Does anyone have any last resort ideas on how to get it to at least come back up to a boot loader screen ?

In the past few days I have received some email messages with well-meant tips and tricks , which I already had tried myself. Nothing worked however ... The damn thing is totally dead .
I have obtained another (2nd hand) Hermes 200 in the meantime, in perfect condition and at a fair price, so I am back in the Hermes business again.
I will use the old one for parts, should I ever need them.
Sorry I could not help.

I am waiting for my Treo 750 without camera to arrive from USA which I ordered
in wise foresight.
I will probably buy a used Hermes with broken display and switch the boards and
use that one as replacement.
Thanks anyways...but what I find strange is that so many Tytns die at the same
time and this more often for the Tytn II generation.
Have a nice weekend!
Cheers
Gentleman, my optimus g is showing some really strange behavior. If the battery is fully charged, or above 60%, it works flawless, after it drops below that, there is a chance that the power button will start locking in the pressed down position. After this happens, it is a no come back, the phone keeps bootlooping until the battery goes dry. At first I thought this was a problem with the battery, I got It replaced and the problem persists. I am starting to think this is a problem with the power button flex cable, and I was wandering if anyone knows how to replace it. I've replaced cell phone's screens and such, I have taken the motherboard out and found the flex cable, but I am not sure how to remove it, as it seems that it is firmly glued to the chassis. If anyone could give me some suggestions I would appreciate it, thanks
My friend got his new HTC Desire 826 in July 2015. He is having issue with his phone, the screen totally blackouts. He doesn't want to repair the phone because it has no more warranty and will cost much to repair. He asked my help to recover any data possible from his phone.
This was the info I got from him: The phone would restart itself once in a while in the recent few months of use (almost the time that the warranty ended). The screen would black out sometimes, a physical hit on the phone helped to recover it. At the last few moments before the screen totally blackout, the screen showed the mirror image of what it's suppose to show (he had to put it in front of a mirror to read the message). And then it just died and never come alive again. He can't remember whether he set the phone to silent mode.
What I did: Removed and put in the battery, pressing power button gives me a short vibration (I assume that means it can be turned on). Dissemble and reassembled the boards, flex cables etc. No burn mark or broken connection seen. Connect to TV using MHL cable, no signal detected. Soft reset by pressing POWER + VOLUME UP button, it vibrated and screen was still black. Since then, charging after turn on doesn't shows red light below the front camera. The metal cover above the motherboard was usually very hot whenever the phone is on. I'm working like I'm blind, omg >_<.
What's wrong with the phone? What should I do? Possible to repair? Some questions I'd like to ask.
1) Using MHL, does the phone screen need to be working then the TV will show what's on the phone screen?
2) Is there anyway I can connect the phone to other external screen and control externally?
3) I'm hesitant to repair the phone, the heating up of the motherboard scares me that the phone won't last long even after repair. Anyone has this phone and how do u go about this heating issue?
Hi guys, I have a really big problem. While changing my le max 2 screen I accidentally turned on the phone without the screen connected, now it keeps vibrating every tot seconds like it is cpntinuously restarting. I tried connecting the screen and only the backlight turn on and the screen is black, not even the touch buttons, and he keeps "restarting". I'm 99% sure that the screen is not damaged and that I have not damaged the phone. Someone have some ideas on how could I fix this? Pls help me find a way to solve this cause I have no money for a new phone :/ Thank you

I tried but it has not worked I tried a lot of combination between screen, battery, wall charger and pc but for the moment nothing worked. Tomorrow I'll try the unbrick procedure just to add it to the list :/
After the unbrick procedure my touch buttons turned on for a sec, then turned off again. They turn on randomly :/ Screen is still black and now when I connect the phone to the pc I see it as "Qualcomm HS-USB Diagnostics 9025". Dunno what to try more
im wondering if you were able to fix it, i have the same problem after replacing my screen
same problem. is there improvement?
Any new here?
Yesterday I replaced my fingerprint sensor, but after putting the screen got the exact problem that the OP guy says, the screen is black, just turn on the back side, sometimes the buttons and so on.
Some one could solve it?
Me too , Anyone can help us please. ,
times ago, i had the same issue on a nexus 5 (hammerhead) after screen replacing. i've solved buying another device and putting the n5 in trash.
For what I know the screen connector on motherboard is extremely delicate.
Maybe you guys have broken it.
Hi folks,
First things first: I know there are a lot of threads concerning the "red light of death" for Huawei and other devices. I already read so many of them that my head is spinning xD However, I have some questions left and I need to distract myself from getting crazy due to the possible loss of data on my phone (and I have to wait at least until Tuesday for any news regarding the phone...)
What happend?
- Phone restarted while surfing
- Went into a bootloop
- Tried a soft reset
- Tried eRecovery --> Not succesfull
At this point I had to leave the train and the phone had turned off anyway. Wanted to charge the phone at the airport and back up recent data. Removed the protective cover and noticed that the battery was bloated. Since I was afraid I unplugged the phone and came to the conclusion that the phone doesn't work due to the defective battery. Back at home I ordered a new battery - didn't help. Phone won't turn on, softboot doesn't work. I only see a solid red LED when I try to charge it. Bought another battery - nothing. Went to a repair shop: This is the point where I start to have questions
They are all very nice at this place and maybe everything will turn out fine but I just can't wrap my head around certain things.
At first they also wanted to check for a defective battery and possible repairing errors since I replaced it myself. Today they called and let me know that the new battery is alright and they now want to order a new screen module. Later today I went to their shop to ask how much everything will cost and also to ask them about the procedure. I asked them why they want to change the display. Answer: Since the battery is fine, we believe the screen cable got damaged when taking out the old battery - its a common issue because the cable is underneath the glued battery. Once the new screen module is ordered there is a good change that it'll work and we can save your data. Note that I don't have to pay for the new screen, since I said that I only want the data back and that I don't need the phone back fully working. So I don't think they suggested it for the sake of making money.
I have indicated that I suspect a hardware problem, but the guy said the motherboard is fine. He continued to explain, that since the red LED is on and the mainboard as well as the battery are fine they assume a problem with the screen.
My questions:
How can they check if the logicboard "is ok" (I asked if they can do micro soldering and since they can't I doubt they can measure the components). Are there easy ways to exclude an hardware error on the board?
Is it possible that the phone doesn't start, vibrate, is not detected by the PC all because of a faulty screen? Any ideas why the LED is visible then?
Doesn't the red solid LED indicate charging? So how come I "charge" while not being plugged in? (LED stays red all the time)
My initial problem wasn't a possibly ruined screen cable/connection but a bloated battery. It just cracked the backcover open but nothing happened to the screen --> Is it possible at all that the bloated battery killed the display module?
If anyone has read this far: It would help me if you speculate with me about the problem, share your experiences or help me in any other way. Somehow I have to pass the time until next week and I'm going insane xD
Thank you so much!
