Hello guys need help, please!
My Xperia Z2 was poor contact in the headset connector, requiring exchange component of that ... I even bought and did the installation (not very complicated) . Before performing the procedure the unit worked perfectly and my battery possessed 30% load, held the exchange of component, tried to turn on my device but it does not respond as it should. The screen shows nothing, just shows a led in red color that flashes 3 times.
Even with the device disassembled i'm tested by removing the battery connector and plugging the USB cable on the device, the screen turns on and quickly shows a red icon battery charging 1%, but in a few moments the phone off automatically, this is repeated in a infinite loop.
With FlashTool and Emma program it is possible to flash some Rom , only ever made this process more than 5 times and even with 100 % completion, the product does not have any reaction. Should re- booting the system but usually this does not happen in fact.

Took on a technical analysis to but could not repair, my components were tested on other Xperia Z2 and everything works normally, it claimed that the main board has a problem , but he would not be able to perform the repair.
Does anyone know how to solve?
Hi Guys,
Greetings to all . So after failing with Googling and trying on my own, i'm here again with another problematic phone .
(Skip the Description if you want, in short i bought my V10 about 8 months back and i didnt have any issues even with heavy usage/gaming)
I bought the V10 H961N Dua Sim variant used almost 8 months back.During my pre purchase research i became well aware of the infamous "Bootloop of Death" faced by numerous LG V10/V20/G4/G5 phones, But the amazing cost/specs ratio and dual sim support was within my budget and i was willing to take the risk that mine won't be one of the "BAD" ones, and apparently it worked out in my favor.
at the start i was too careful not to even open too many tabs in chrome, but with time i became confident and since after a couple months of buying it i've been using it to have over 35 chrome tabs open at a time, playing some heavy games and compressed movies.
Played PUBG Mobile almost daily for the last month or so, and it just heated up same as my Xperia Z5, with no issues and ho lagging/bootlooping/crashing once.
THE PROBLEM
This Tuesday night, as i was sitting in front of my laptop with the V10 on charge infront of me, downloading several versions of Angry Birds from the playstore (i download a bunch of apps/games at a time and then delete the ones i dont like later) and also it was updating some of the installed apps.
battery (last i checked) was just over 76% or so, and the next time i looked at the phone it was showing the LG Boot Logo (not the animated one, but the static "splash logo" that shows up at the beginning of boot process) . it had turned off and rebooted by itself during charging.
i thought it was nothing, waited for it to complete boot, but when it took longer than normal i pulled out the battery , tried to boot again but again got stuck at the boot logo.
Several retries, same result.
Current State of the Phone
Model : H961N Dual Sim Variant
Firmware : Official Nougat H961N30a_00_0519.kdz Flashed manually via LGUP about 3 months back.
Rooted : No
Bootloader : Locked/Stock State
Problem : Phone gets stuck on LG logo when turned on, waited for upto 15 mins, wont go forward.
There is no apparent overheating i dont feel the phone overheating or anything during boot up process, battery is also normal temp.
JUST ONCE, RANDOMLY, YESTERDAY MORNING IT GOT PAST THE BOOT SCREEN AND WENT UPTO THE LOCK SCREEN, EVERYTHING SEEMED NORMAL AND IT SHOWED THE SCREEN AND ALL THE STATUS ICONS, THEN REBOOTED AFTER LIKE 2 SECONDS .
What i've tried so far
Changed Battery, Didnt Work
Can't get into recovery using hardware keys., so cant hard reset it. (the Vol Down key on it sometimes doesnt work so i dont know if its the same thing causing the Vol Down + Power button combination to not work for getting into recovery mode or i am having the same problem as a lot of other users who also can't access the stock recovery on LG V10.
I can get into "Download Mode" by pressing Vol Up and plugging into the USB port of my laptop.
Phone is not detected by LGUP or Device Manager in windows. if i connect it while powered off, it shows the "charging Screen" for a second, reboots to the charging animation screen and then continues on trying to boot by itself. (yes, my v10 cant charge while powered off, it turns on when i connect to wall charger always)
if i connect it to the laptop while in "Download Mode", still not detected.
phone is not visible anywhere in Device Manager, not detected by LGUP, LG FlashTool, Uppercut in either download mode or connected to laptop while powered off (as it continues on to "charge and power on itself")
I used this same laptop to flash the official nougat rom on this phone about 3 months back All Drivers are installed, using the same version of LGUP as before, with uppercut. also tried with LG FlashTool. but this time not detected by windows/LGUP/LG FlashTool. LGUP says no phone connected, the "COM/Devices" list shows up empty.
Also Tried doing it on another laptop with completely clean OS (free from any previous drivers/apps/android related installations), same results.
Tried it on my office desktop with Win 7, no joy .
Tried several different USB cables (long ones, short ones, and they are all good quality), didn't help either.
Kindly help me in recovering my V10, as its not even detected by windows in "Download Mode', which i can't understand at all.
Any help will be greatly appreciated. Following is a list of the versions of drivers/apps i have tried so far.

LGUnitedMobileDriver_S51MAN312AP22_ML_WHQL_Ver_3.12.3

Hello there,
First of all Extremely sorry for such late reply, after not having any internet access for quite a while, I just t got a chance today to check my emails and any notifications.
I had to disassemble my V10. I'm not sure about the G5, but on V10 the volume keys are a separate flex cable module connected to the motherboard, and the market here is full of dead/bootlooping V10s and G5s so it was an easy replacement to find and install.
But still the problem wasn't resolved.
For the stuck on logo issue, i had to get the cpu reballed on the mobo as a final effort, after trying and failing on everything else for about 2 months. Which was strange because I had absolutely no overheating issues prior to the V10 dying on me as well as no signs of overheat when it was stuck on logo, so I never suspected the infamous "loosening of the cpu chip on mobo" on V10s, G5s V20s etc as the cause of my actual problem.
Also this might be worth pointing out that since my V10 was already disassembled, I decided to install a heatsink (several guides and videos on that available online, do on your own risk).
And also decided to retry my "original" volume keys module.
I found out that one of the connector pins on the motherboard were bent so I very carefully straightened it up, as well as cleaned up some gunk on the module itself under using rubbing alcohol.
After drying it up, it worked flawlessly for a week or so before the volume down key stopped working again. I guess the connector pin under it slipped again, but because of my extremely busy routine now, and also just not feeling the need to take it apart anytime soon so just using my phone just as it is for now .
For volume changes I just use the notification bar, or press volume up once to bring up the volume slider and then lowering the volume form there.
For taking screenshots, I've installed "screenshot touch" app from playstore (free). I already found the screenshot method on V10 quite inconvenient anyways, and the "Capture+" feels too much work for just a screenshot so the app works for me .

Thank you for replying. I implemented the same workarounds for my volume keys also but failed to think of recovery since I usually boot recovery from shutdown menu or term emulator.
I fixed my g5, sounds like we have similar button hardware, I had a few pins that weren't contacting the back of the case which I think is grounding it....I sent them up a bit and was able to boot into twrp. There glitchy again but I just pinch the case a lil and they work(time for a new phone lol)

Good to know that your issue was resolved
Hi there,
Over the years i've done several smart phone repairs, screen replacements, batteries, new cases etc. All of them without any problems. A Few days ago a friend asked me to replace the case and screen of a Huawei P20 lite. Everything went fairly smooth, however after i finished replacing the parts and put the phone back together it does not turn on completely, only the charge light turns red and the phone is vibrating non stop while on charger.
Note: The phone has not been used +- 4 months before repair. When i remove the charger the phone dies again. Sometimes when powering up, the boot animation starts (max 2 sec) but then the screen goes black again (vibrating continues and charging led stays on). The battery was a real pain to get out, so it took some light bending to get it out. Not sure the battery is causing the issue though.
What i've tried:
- Charge the phone with different chargers/cables for 1 hour +
- Charge from low power charger for 4 hours.
- Leave the phone 2 days and try again
- Took it apart again and put it back together, exact same issue.
- Try to start the phone without battery/screen/camera's and other devices that are not mandatory, same issue persists.
- try to get in recovery etc.. no success.
Could anyone help me how to find the culprit of this issue, im really lost.. Any tips are much appreciated.
Thanks in advance!
check batery by multimeter first and if posible use other for test.
take tooth brush and clean all connectors in phone also.
Did u test screen before asembly it ? it was works ?
Hello I have the same problem and I fixed
Dear,
This is solved by changing the sense of the motherboard cable, incredible but True
Hi guys please help me out. My redmi note 5 ai dual camera phone went off for no reason a week ago. The phone had xiaomi.eu rom installed 1 year ago and since then I never messed with custom roms or anything. Until last week, the phone was working fine. I left my phone on my bed and 30 minutes later tried to turn on the screen and it wouldn't open. I became scared and tried pressing the power button for a while but still no sign of life. Then I charged the battery for 5 hours to be sure it was not a battery issue but still I saw no signs of life. I then plugged my phone to the laptop and it said 'Qusb_bulk' which means the phone went to edl mode.
I then downloaded qualcom driver and tried to flash the phone using mi flash to recover it but nothing seems to work. I even tried qfil but there is always some kind of error which prevents the flash from completing. I tried the anti test rom and still an error happens at 10 seconds saying storsec.mbn error. Then I opened the back panel and disconnected the cables and put them back on again but still the same error happens during flashing. At this point I have no hope for my phone anymore? Do you guys think it's a hardware issue or something? With the corona **** going on I can't even go to repair store to get it checked out. Please help I was in love with this phone and it's hurting to see my phone in this condition.
Hello! Today my Honor 10 touchscreen just randomily stopped work (It has been quiet a hot day). It wasn't dropped or anything, does anyone have any idea why? It boots just fine just litterally the screen is not interactive. I have rebooted it god knows how many times and tried loading into Safe mode aswell, I opened it up and unplugged everything and plugged itself back it and nothing still. I can't factory reset it as you need to type Yes. If you know how to fix this problem much appreciated! Or if you know a PC software which lets me control my phone by plugging it into the PC??
