Dear everyone
My nephew just gor p970 yesterday
for the name of curiosity, i checked and tried the phone.
the rom is 10a
i did root using gingerbreak
it was succeed. i dont kno why i has to root anyway.
actually no need for installing the special app.
then i registered the phone to access to the market.
installing some media music player with lyrics lrc.
the phone then warns the battery just 15%.
i plugged it to the power AC, and continues selecting the music apps.
after several minutes somehow it hangs, the music is jammed.
i pulled the power cord.
i tried turn off by hold the power button not helped. then i removed the battery.and put in back.
restarted, the 4 low phone button was blinking, the screen was grey.
for several minutes, there's no sign froyo menu.
hopeless, i removed the battery.and put in back agin..
i tried to turn on the phone, and it just like no sign of life. no lg logo.
just quiet like corpse. oh dear, what i have just done?
i dont think it is bootloop case, and i dont think it is software issue, right?
charged for 2 hours without any sign of charging, no led indicating what so ever.
still like a dead mobile phone without battery.
Just remove Memory card sim card and flash ur phone with latest V20o or v20e firmware using SMARTFLASH tool. U will get it in development section serch for post [ROOT] v20b and v20o i hope ur phone will work again

There's no way to turn on the phone at least to software upgrade mode via hard reset or something.
no screen / beep / led that was turned on when i push the power button or even when i charge it. totally gave up.
Remove your SIM Card, SD Card and Battery. And Press Hold Volume + Key while Plugging USB Cable to your phone. Your phone should be in S/W Mode, then try Flashing it using SmartFlash.
Check your power cord,is it connected or not?
i mean, it happened to me once (the power is off )
Can't get into the s/w upgrade or what?

i checked the power cord with others also, nokia phone that has same power cord.the nokia was charging, where the optimus was not, not given any clue charging. no led. no sound. nothing. creep...
i just went to the store, and checked with the demo stock battery. it's dead cannot turned on, same. no sign of life.
i gave it back to my nephew to check it to service center tomorrow office hour. i am felling bad bricking his phone. i never bricked original rom smartphone before. it is so badly there's no sign of life.
the question is remaining in my head: this because of the not so qualified first optimus black stocks since it is using 10a, or my miss-use?
i did nt flashing custom rom inside it, i don't think i miss-use it.
it;s no sign of lg boot or minimal sound of turned on, i don't think sw upgrade manually in house will help, right? i did try the hard reset method, up/down volume button with power button pressed at the same time continuouslyand i think plugged in also with usb computer.
there's no new usb device detected.
there's no sign of going to s/w upgrade.
this is just not my day. maybe i have to many sins for jailbreaking
hopefully he can have changed for a new one, rather than serviced for weeks.
Just volume up and then plug in the usb cable. That's how you enter sw mode. But no sign of life at all, is really strange...

same thing with mine
i ve been usinfg OB for 4 months now, and ve used all sought of roms since then and no problem. presently was on sapphire rom 2.2, tried making a call and all of a sudden d screen was off colour, so i removed battery, placed it back in and can't even get the LG logo when switching on. On using volume up plus power key it entered software upgrade mode but this does not show on the screen, used smart flash and it even made it worse. i ve taken it to LG centre now waiting for reply.

It's okay
In this case, i think it's not your fault, it's a factory fail i think
If its guarantee hasn't been expired yet,sure he can get a new replacement

are u using the original cable because other kinds of cables won't work

Like agent205 said, it might be a factory problem. My phone died also like that. I put it to charge and in the morning I just couldn't turn it on. So I use the guarantee and they sent it back after 3 weeks, just saying that they replaced the motherboard (and also replaced software lol). Good luck !

The internal flash memory is soldered to mainboard.

yes it wont respond to usb without battery , no signal, and same with battery. ;(
Can you charge the phone?
Vol+ and insert USB does not work, no sw Upgrade Modus?
When yes, flash firmware again.
When no, its hardbricked, then send to service.

One month ago,i dropped my Htc one mini 2 in a pot of water. I should say that i rapidly took it out (3-4 sec.)
The screen remained on for just 10 seconds, then the phone became completely dead. I have used rice, silica gel and i managed to turn it on,but the phone was rebooting every 5 minutes. At least no other part was damaged, while it was on i could connect it to WiFi, listen to music to speakers,play games... I`ve sent it warranty, they told me that they can repair it after i pay ~150 euros.
After i received it, i wasn`t able to turn it on at all. The led was blinking and all i could get was the logo with the red battery. (photo in thread). I succeeded to turn it on by pressing the power button+volume up 2 minutes.
Battery shows 0%, 0 mAh, 3,37V.
Is it a dead battery?What should i do? Before warranty the battery was completely fine.
I live in Romania, and here there are only 2 authorized services. Except that, i trust no one.
Please, if u know some solutions that may help, answer this post.
Thank you for patience and help.
PS: I want to highlight the lack of water resistance of this phone...

you should contact the service that done the repair and explain that the phone its not working.
Thank you for response I sent a mail to the service, but they didn`t answer.
I managed to fix the charging problem . I opened the device properly, i disconnected the connectors from the motherboard, i cleaned them and then when i reconnected it all worked. Phone charges to 100%.
BUT, i get random restarts. They are absolutely unexplainable . It`s really annoying.
Finally, if i fix the restart problem the phone is brand new.
It may be a software or a power problem !? (after restart the battery history gets deleted)
I guess it isn`t a hardware problem as long as the phone does not restart at all while it`s in RECOVERY or FASTBOOT.
If u have any ideas, everythink would help. I`ll come again if i fixed something. (i try to clean cache and data and factory reset)

it could still be hardware. Fastboot or recovery does not use all the hardware.
try to run Diagnotics
call *#*#3424#*#*

True, didn`t think about that. I found a service with free diagnostics and i`ll visit them asap.
Recieved my mi5 yesterday and used it for about 15-20 minutes (just playing around with MIUI), turned the screen on and off multiple times but suddenly the screen wouldn't turn back on I rebooted the phone (hold power button) but nothing happend when turning it back on.
the capacative buttons and charging LED works as well as volume up and down (I can hear the volume change sound). After about 4 hours it suddenly worked again and I thought it was fixed (it was not), I booted into fastboot and unlocked my device but when I try to turn it back on the screen was dark again, and after several hours it still doesn't work.
There are other people with the same problems but I don't think anyone has been able to fix it.
Has anyone else encountered this? If so, did you fix it? I thought I'd should mention it anyway.
same problem..no FIX !!
Few months ago I also received a 32gb device and had exactly the same issues you mentioned. First with MIUI and locked bootloader, then unlocked and tried 3 different Rom's, MIUI 7, 8 and Lineage OS. No difference.
IMHO a common hardware issue on some devices, mine has a LGD Display. Meanwhile I got another one, which is working fine, but have this faulty one still here, for spare parts right now
Would help if someone could state whether this issue is screen or motherboard related, so I could maybe replace parts and use or sell.
Sometimes it went completely off, no capacitive buttons, no volume sound, no reboot possible. But battery not empty. Had to disconnect battery or wait one night until it would respond again.
Also observed less black screens in warm surroundings, had more problems being outside in winter.
yesterday my mi5 died with this problem...
hope the warranty over tradingshenzhen works fine...

Want to share following with people who experienced also blackscreen issues with Mi5:
lately needed an identical Mi5 device to recover some apps from another device and decided to try with this "damaged" one from last year. Fastboot flashed Miui9, then wiped, installed latest TWRP and LineageOS 15.1. Did my backup/recover tasks. Then I just kept using the phone, because I was curious how long it takes until the blackscreen issues would appear but they didn't.
Device is working without any screen issues now since a week or so Seems like new firmware has fixed something, at least for my device.
Hi, my Xiaomi Redmi 4X (santoni) got a strange bug this morning, no audio from the speaker, I tried to see if there was something on the jack port but nothing, then I reflashed the same rom (Miui Pro, never had problems, used for three months) but nothing happen.
In the evening the smartphone got bootloop, if I try to access to the fastboot mode graphics glitches, recovery is not accessibile.
Should I have to call the warranty service or can I do something by myself?
Sorry for my bad english.

Can u sent a pict??
Bootloop on first logo? Or second logo? Or blank screen?
Or maybe u can try to flash it with edl cable ( Deef flash cable )
No, sorry, I can't send any photos, at the moment the phone is on black screen (it is turned on), the classic fastboot pic doesn't appear anymore.
I'm waiting for the battery discharge, then I will try to recharge the phone for one houre...
Hello, guys!
So, two days ago I just checking my phone left on the table, a notification arrived, when I unlocked it, the phone turned off and has never returned. It has around 22% battery, and I have been using it for only 7 months. There was no physical damage (cracks, water damage, etc) or overheating. The phone (chinese market with global rom) was updated to the last MIUI 13 OTA around one week ago.
The phone:
- Wont turn on (none of the buttons combo work/ no fastboot)
- No sign of charging using any charger, neither through wireles or usb
- My PC doesnt recognize the usb connection at all
Since I had to import it, the warranty is long gone. Ive read about shorting the testpoint for getting into EDL mode. I just bought the tools and gonna try to do it and contact the telegram guy again (he told that he can only help me when I get the usb working).
I am really disappointed with this. I have a 6 years old Mi 4C and a 4 years old Xiaomi A1 and they both still work, never expected a phone to be gone so fast and completely by itself.
Since I lack hope on making the EDL work, is there anything else I can do?
Every thread I read, people at least can get their USB to work.
Thanks!
