Hello, following my device does not start anymore.
- PC does not recognize it, it is not because of the drivers because my Zuk z2 pro recognizes immediately
- no vibration
- no Zuk sign
- The display of what happened when I press about 1-2 minutes on the power button and plugged into the charger that the LED flashes.
-Have ordered a deep flash cable from China and there it is not recognized on the PC
- I have removed the battery and connected to the PC and it starts flashing white Led
Another idea what I can do before I throw it in the trash. Should I buy a new battery? Thank you

Hey guys!
A few weeks ago my phone(z1c) fell on the ground (directly onto a metal bar) and as a result the touchscreen cracked and died. Since I didn't want to spend much money for a new display+digitizer I bought the Z3 Compact. But a few days ago I found and bought a cheap one from ebay to revive my touchscreen-cracked Z1 compact as a secondary phone. Boring story - I know.
Well, yesterday I disassembled it (dumb me startet to dismantle it from the backside till I recognized that I can't swap the screen from there. (I completely dismantled the backside at that point)). Since I didn't have enough time to fiddle around with it any more I left it dismanteled till today. So today I reassembled it and swapped the display and there I am:
My phone is dead. It wont turn on. It just shows a red led when I connect it to the charger. I can't get it into Flashmode nor fastboot mode. I tried the Power + Volume Up reset as well as the 'Off' button beside the SIM-slot. Doesn't change anything. If I connect my Z1c to the charger with the battery _disconnected_ it slooooooowly blinks red. (Like 10sec red 1sec off).
Any ideas on how to proceed?
Ok now I tried with Testpoint but I can't seem to get it into emergency flash mode...
This is what I'm doing: Connect TP to GND > Plug In MicroUSB > Red LED is on > Disconnect TP > Red LED turns off after a few seconds
This is what happens without TP connected: Plug In MicroUSB > Red LED is on > Red LED turns off after a few seconds > Red LED turns back on > ...... (flashing slowly)
Am I doing something wrong? I attached a pic of the mobo
@munjeni D:
Here i've another pic of testpoint
That seems to be the same pin as I am trying to use. Still no luck to get it into emergency flash mode :/
Hi All,
I recently tried to fix my older sons xperia zl, The phone would not power on, it did not show any signs of life when plugged in to a computer. Tried all the different button combos and the off button at the back of unit but still nothing.
So I opened it up and checked each component visually, did not notice anything wrong.
I decides to see what would happen if I disconnected the battery and plugged it in to just usb to the computer.
Well it showed up in device manager as a SEMC flash device, and the red notification light came on. Then it started to try to turn on without me pushing the power button, the screen gets to the sony logo and then goes black and starts again.
The next thing I tried was to flash a new rom to it, under Flashtools it automatically goes in to flash mode, found my rom and hit flash and it completed the flash. Disconnected the usb , connected the battery but nothing no power and still nothing in device manager.
Another weird thing that happens is that while the battery is disconnected and i hold the vol+ a blue notification light turns on and the phones goes into fastboot mode.
I initially thought the battery was the problem so I ordered a new one and installed it but the same thing keeps happen, anytime the battery is connected the phones does not react to and buttons, even when the usb charging cable is also connected.
I am wondering if someone has a schematic or know of a capacitor, resistor or fuse that is stopping the phone from recognizing the battery.
Any help would be greatly appreciated.
Hi everyone,
(sorry for my bad english, I'm Italian)
two days ago I've buy an used Zenfone 2 ZE551ML 64gb ROM, 4gb RAM.
The seller tell me only display wasn't working.
I put it charging immediately, and bot LED and vibrating working sussefully.
But, no battery logo on the display (display KO).
So, I changed the display and when was charging, battery logo was ok.
But... a strange think happens.
Few minutes later, still charging, no BOT led, no battery logo...
I push botton to turn on it, but was dead... no vibrating, no led, nothing!
I tried to change battery, change usb dock, but nothing helps.
At the last chance, I plug it to PC.
When I plug it to PC, moorefield device appears but I don't push any botton!
Immediately, when I plug it, moorefield device appears.
If I push power button for few seconds, moorefield device disappears, but if I release button, reappers immediately... so strange.
Last chance, I tried to flash it with xFSTK but don't work.
Here the messages:
- GetAck - ER04;
- LogError;
- Error Code: 40 - ER04 - SecurityInit
Then xFSTK aborting...
Any tips??
Thank you so much.
No one can help me? Thanks...
So I was talking on my Z2plus and I dropped the phone it was in its original case.
no physical damage to the phone.
but it won't power on now. tried all the button combination nothing works ,no vibration nothing.
When I connect it to the charger the notification LED blinks.
Connected it to my laptop too still nothing.
any idea what to do with it now?
UPDATE: saw this suggestion in the official lenovo forums to remove the back cover and unplug and plug back the battery.
tried it and it works.PHone has started .
UPDATE 2: The phone has shutdown again and unplugging and plugging the battery doesn't work any more. but notification light blink when connected to charger whether the battery is connected or not. so I think that battery might be at the fault here.cant do anything about it as lockdown is going on.will update once lockdown is over.
