Question [HELP] Lenovo Phab PB1-770M Dead after Battery 0% - Lenovo Phab Plus

Hello, for 5 days I've been looking for a solution to this issue...
i have Lenovo phab plus PB1-770M, when i got battery 1% and gone to 0% (phone shutting down)
i went to my charger to charge it back, but phone said goodbye at that shutdown!!
Charging led doesn't light up, screen doesn't show its charging.. so i waited for about 1 hour thinking it will come back... but nothing
even worse, trying to enter the phone into EDL mode by pressing volume keys and inserting USB cable doesn't work, computer doesn't even detect the device.
so the phone is kinda dead just after being 0% battery.. (it has official software on it)
but yet testing the board outcome voltage to see if the socket/charge circle works and the battery receiving current, is OK.
so battery is charging in dead phone.
i don't know how to fix this or if there is another way to enter EDL mode IF the phone is only software bricked (like corrupted aboot/boot partition).
sorry for the long post.

Did u find the solution bruh? I am also facing this problem...

[Q] Black screen but charging led lights up

Hi There,
Yesterday morning I went to work with a completely charged Moto G. When I arrived at work my screen was black and had become unresponsive.
The powerbutton doesn't wake up the phone, tried several times, holding it for more than 150sec. When connected to a charger (tried multipe) the charging led lights up, not blinking.
I have read on a motorola forum that this could indicate that there's insufficient power in the battery to activate the display.
However it was completely charged.
My Moto G has an unlocked bootloader, is rooted and has a custom rom (C-Rom, [ROM][AOSP][KK][12/05] **C-RoM** -4.4.2- -v6.5)
Is there anything I can try or is my phone a brick now?
Thanx in advance
The same problem
I am having the same problem too.
My moto G drained its battery until it shut down. Then i promptly went to charge it. The screen is blank and and notification light is on.
snooze1973 did u find a solution or is it now working?
PS My Moto g bootloader unlocked, stock rom,rooted and it is on the Faux123kernel
Thanks in advance
No luck Yet
No luck yet, left it on the charger for a whole night, still just the white charging led. No response to the power button.
But I refuse to believe it is completely dead. Before I had a HTC Desire S, tried many custom roms, never bricked it.
I just can't imagine what happend the day before yesterday.
Perhaps I'll try and find a more powerfull charger.

I think I found a solution. I followed these steps
1. Charge your phone via USB cable on your computer.
2. The white notification light should come on.
3. Then, do not touch any buttons on your phone.
4 The iconic Battery Logo(white background) should appear after several minutes.
Followed these steps and my phone eventually turned on
Good luck!!
Still no luck, trying a different cable (blackberry) now.
Not working for me, still just a beautiful white led indicator.
Start to think it's probably dead. Or battery thinks it's drained somehow.
Maybe anyone else has an idea?
Ok, I opened the Moto G and disconnected the battery, reconnected it after 10 sec. still no luck
Odd thing though and not very promising is that when the battery is disconnected the charging led still lights up when charger is connected.
Could this just mean that only the battery is fully drained or that the device is messed up?
Guess I going for a new one.
See if a new battery helps
Bought a new one today, so I can try and fix the other. First I will leave it for at least 24 hours.
Perhaps I will exchange the batteries at one time to see if that helps.

anyone could help please
Black screen but charging led lights up
I am experiencing the same issue.
I bought a dead moto g for part replacement with my current moto g. Just out of curiosity, I plugged in the charger to the newly arrived moto g and observed the similar behavior.
To go further, I swapped the battery and tried to turn it on, and voila, it boots!! It has C-ROM. But it won't charge the battery any how. Its again back to
original behavior : No Screen, No Battery Charging, Only notification LED glows. I kept it on charger for whole night, but no luck.
The notification LED turns on even if I the battery is removed and charger is plugged in. What does that really mean?
Is there a probability that the charging circuit is broken? or it has something to do with bootloader, C-ROM and custom kernel? Does any one thinks reverting back to Stock ROM will help out in any way?
Same here...
Exactly the same with my little brother his Moto G 4G (1st gen) (stock rom, BL unlocked & rooted).
Solid white LED when plugged in, no other response.
The most advertised trick does not work (step 6: flashboot screen doesn't show up)
[SIZE=+1]Q28: Moto G will not power up (addition to Q16 and Q25)[/SIZE]
Plug it into the charger
Hold the VOL DOWN key
While still holding the VOL DOWN key, press and hold the POWER key
Hold both keys down for over 120 seconds. This is more than two minutes and will seem like a long time. You might want to time yourself to make sure you hold it longer than two minutes.
After holding the keys down for more than two minutes, release them.
The Flash Boot screen will display, and the Normal Reboot option will be highlighted
Press the VOL UP key and the device will start a normal reboot.
If you have tried the above and it didn't work, try this:
Plug in the phone for 15 minutes.
Proceed to Step 2 above.

It has been an hour on the charger of my Asus T100 Tablet (5V, 2A). Still no luck...
Due to the lack of other solutions, I guess all our phones are ready for RMA...
Update: an overnight charge on a 5V 1A charger did the trick. White led was gone this morning, booted normally.

I don't know why a USB charger and a PC connection should make any difference when the phone is not booted up.
I had the same problem. I solved it by removing the battery by opening the phone (mine was out of warranty) and taking it to repair shop where they charged the battery for an hour. Then when I put it back in, the phone rebooted normally with 10% charge.
But ever since, my battery life has deteriorated. Doesn't even last one full day. And I have had the same issue twice. I think I need a new battery.

I have a simple solution for that I have faced this issue long time ago and now I know a permanent solution. You all have usb cables in your house...just took a old one and cut it from the mini usb side..there are 4 wires...you have to care about red and black..open your moto g battery and took it off from the phone now connect the usb cable to your pc and touch the red wire to the positive and black to the negative ...just do this for 45 seconds and immediately connect the battery to the phone and connect the charger...phone will starts charging from 0 % pls do not wait to connect the switch and back cover just charge it upto 20 % the cover it up.....DO NOT LET YOUR BATTERY DRAIN MORE THAN 30% AS THIS IS COMMON PROBLEM IN LI ION BATTERIES...

Interesting, but how did you determine the negative and positive terminals on the battery flex? Can you, please, mark the attached photo of the battery of moto g to help the community?
Also, as a side note I think I discovered a solution - I connected the phone to my PC's usb 2.0 port and held the power button for 2 minutes - at which the LED blinked momentarily and then continues to shine. I left the phone connected and continued to browse for solutions to this battery charging dilemma - then about 5 minutes the LED stopped shining (and I breathed a sigh :silly: !!! becaue this is the sign of battery being charged!) and after about 30 minutes of charging I turned the phone on and it was 16% charged. Well I haven't been able to reproduce this solution (since, I have been extra cautious with the battery now!) but I would surely like to know if anyone can reproduce this solution:
1. Plug in your phone to USB 2.0 or 3.0 port with original moto g cable and confirm that the LED shines continuously.
2. Hold the power button for 2 minutes (which I discovered to be a long time if you just continuously stare at the phone!) after which you will notice that the led with blink momentarily before continuing to shine continuously. (I suggest you continue holding it for another 2 minutes after which the led will blink again momentarily)
3. Leave the power button and leave the phone attached to the port for at least 30 mins before attempting to power on.

Does your pc detect anything when you plug usb cable ?
Yes, it detects, but then disconnects, can it be a problem in the battery?
Chances are you have received a refurbished device or defective battery.
Try and find another Mi4 user for trial of the battery or let's see you need to contact the vendor soon.

Charge via wall adapter. Leave it for some time.
PS: When your battery reaches 9-10%, it is advisable to charge it back to 100%.

I just got this issue 10min ago. Havn't depleted the battery on the phone for a very long time, my guess is that it hasn't calibrated the battery in a while or something like that. Will keep it in the fast charger during the night and then i'll reply here.
EDIT: Normally the red LED is constantly on when the battery is low and it's in the charger, now it's flashing which makes it look a bit more scary.
EDIT2: Works fine now after a night of charging
Charger could be not pushing enough voltage to charge battery. Try another one to see if it remedies the issue.
I do have the same problem with my Mi4. I wanted to start the update in the Updater app (to Android 6 version of Xiaomi.eu) and suddenly it turned off (at 100% battery). When I connect my phone with my computer it is recognized and all the partitions are mounted. And with all I mean all. There are about 7 partitions mounted (Linux and Windows) and they keep being mounted until I disconnect the phone. I let my Mi4 on the wall charger for 24 hours (2A Samsung one which charges all my other devices without any problems) but I still have the blinking red light after connecting it to the charger. Any other things I can do to get it running again?
EDIT: I can't see the phone in fastboot or adb and when I keep the power button pressed for about 10s it seems to disconnect and instantly reconnect the phone.

I solved this problem on my own. Even though the phone doesn't show up on the fastboot devices list you can use the Mi Flash Tool to flash the fastboot update (http://xiaomiadvices.com/miui-7-flash-fastboot-rom-on-xiaomi-phones-using-mi-flash-tool/). The drivers installed with the Mi Flash Tool for the Windows 10 Mobile Release (http://en.miui.com/thread-189369-1-1.html) recognize all the partitions as one device and show it with a cryptical name in the flash list.
Hi ! I fully charged the phone and after it shuted down. It doesn't starts. PC doesn't see it. When I'm plugin the wire just half way into the phone the red light stays on for a few seconds and than nothing at all. Can anyone help me?
Push power+vol up for quite enough lets say 20 sec
same problem here i kept charging for whole night but phone not getting on.. only red LED comes when kept for charging and not detected in PC also. Can any 1 help on this
I had the same problem ( strangely,it occured after a whole night charging, f... knows what happened)
Tried to change charger. No luck. The phone won't even boot by pushing Vol down+ Power
Solution: I simply connected the phone to a portable external charger, and tadaaaa !!! it was brought back to life !
Hope this helps

Battery dead, not charging, stuck on "low battery screen", bootloops with forceboot

Battery dead, not charging, stuck on "low battery screen", bootloops with forceboot
Hello people, this is my very first post on xda, even though I've been lurking around for about a year. The community has helped me a lot, I'd like to thank you all for that.
Back on topic though! My error seems to be very similar to the one here.
I was watching some YouTube, battery sitting on a respectable 85%, when it suddenly shut off. Not the usual "shutting down for low battery" kind of shutting down, it was istantaneous, more like the battery was unplugged from the phone. Which is clearly impossible. I tried to boot it using the power button to no avail. I connected it to the charger, and the "the battery is too low" screen popped up. I left it at that for about 45 minutes, then unplugged from the charger and tried to boot. No success. The battery didn't even charge; the charger should be is fully working.
So I tried leaving it plugged to the charger and force boot the phone via volume down and power button; it attempted to boot, but stopped midway through, bootlooping until I unplug it, at that point it shuts off again.
The loop goes like this: OnePlus white logo (normal when you boot), radioactive kernel loading, reboot and repeat. That happens, again, until I unplug it from the charger. Then it shuts off.
EDIT: If I try to get into bootloader instead (volume up + power), after about 8 seconds of me pressing the buttons the screen just shuts off and doesn't react to any more presses (even while plugged). If I unplug and replug it to the charger, I'm back to square one (low battery, please charge).
PC doesn't recognize it. It makes the "the battery is low" screen pop up, but nothing else.
Here's some phone information in case you need them.
Phone info:
Rom: NucleaRom 1.3 (+ Radioactive kernel which comes with it) got it from here
Xposed modules: Youtube Background Playback, AdAway
Root: Yes
Thanks in advance everyone.
I doubt it would be software related if it does it even when in bootloader. It could be the problem I had with my nexus 7 a few times. I needed to charge it like all day for it to even turn on. Either that or faulty phone/bad battery. I hope it's just dead

Hello there, thanks for taking the time to reply. Yesterday I worked all day to try and make sense of the problem. I could have just bought another phone but I'm fairly attached to this one so I went deep.
I was fairly sure (like you) that it couldn't be a software problem, so I looked at the logic board of the phone; turns out (correct my poor technical wording) the bracket (connector?) for the battery on the logic board was coming off from the motherboard itself (the battery was indeed attached to the bracket, the bracket was just coming off of the board). What I did was just reposition the bracket and pushed it down with a bit of force on the board, then replugged the battery in the newly restored battery plug, and tried my luck. It booted! Back at its original 75%-ish.
My only guess would be that due to a fall the bracket got misplaced, but stayed close enough for it to still make contact and never actually shut down, until yesterday. That was... Quite an interesting ride.
Thanks for replying, it was indeed a "faulty phone", but I just couldn't leave it at that without trying
I'm glad it worked out for ya
Not work at all ...
My phone its show the logo on charging or low charge but its stuck for this for while full battary is empty...

Overnight Charging [Redmi 4 not Booting ]

I don't know what happened to my phone (Redmi 4), I kept it overnight for charge and when I woke up to check my phone , it wasn't turning on at all.
(I kept it switched off at night while it was charging). It wasn't the first time I charged my phone overnight.
Tried Trickle Charging ,it's sill not booting . Although now I am able to boot into fastboot mode.
Is there any chance it might have been bricked ?
Any solution or would I have to pay service station a visit ?
Also whenever I press and hold power button it flashes mi logo for less than a second and switches off , also the led which used to get on during charge isn't getting on.

Help! Battery dead

Hi,
I was given this phone without knowing any history of the problem, (if i get information i will update).
The phone doesn't power on, not even on recovery or download mode (i used these directions: https://thedroidguy.com/fix-galaxy-s8-wont-power-troubleshooting-guide-1079105). Connecting its charger seams to have no effect on the phone.
No led indicator no nothing...
The charger is charging another phone i tried.
Any ideas on how to bring the phone to life again?
Thanx in advance, i know the information is not enough but i expect information update soon.
* Update
The phone had stuck in a boot loop and it left charging for a long time.
Then it was left on battery untill it died out of battery and want power on or charge.
