Reboot & charging issues? - Lenovo Zuk Z2 Pro Questions & Answers

I stumbled over two quirks/bugs and I want to know if someone else has seen these.
1. When I power off the phone and try to load the battery with the charger it starts and stops loading forever. This infinite loop occurs with the original charger and with my "old" Quickcharge 2.0 charger (LG), too.
2. When the phone is connected to my PC and I want to reboot it never finishes. Screen goes dark but the phone won't boot up anymore. All I can do is a reset (volume down + power).
Just me or anyone else?
EDIT: Everything ok with the phone, usb cable is broken. Got a new one.

i have the same issue. did you change rom?

Button ROM reads wrong battery power.

Hi,
I want to update my ROM from a standard WM5 to WM5SE rev 5.0. Following instructions, I downgraded with the button ROM to let me CID unlock my G3 Jammin. The butotn ROM installed, but when it reset it would not boot and both the red and blue lights would flash together, the screen would flash on, and then it would shut off.
This pattern is repeated every couple of second and doesn't stop until I pull the USB cable out, after which it repeats once more then switches off. I can't turn the phone back on with the power button. From here I can get back into the locked cycle by powering on with the USB cable plugged in (back into reset cycle), or into windows with the mains power cable (see below).
I think this means that the problem is related to my USB cable being plugged in. When I put the mains power cable in, the PDA will boot into windows. Related to this is what I think may be the main culprit. In setting, Windows says the battery is on 0%!!! Even the mains power cable doesn't seem to ever charge it, so I think it must be a software problem related to the ROM. Inceidentally, I recall that I had to softreset near the end of Button ROM's install, perhaps this is part of the problem...
Now I can reinsert the USB cable only during the Windows boot process, which as mentioned has to be initiated with the mains power cord, ie. I swap over half way through. If I change from mains power to USB after Windows has fully booted then the phone resets and the above reseting cycle occurs again.
Once Windows is fully booted with the USB cable in everything is stable and Activesync detects the phone. The problem is that when I try to reinstall a stable ROM, the update software throws the following error: Error [220] mains battery power. So the software I believe is reading that the battery is less than 50% (ie. probabaly thinks there is 0 charge left) and I can't reinstall a new ROM!!
The other thing to note is that I can get into bootloader mode with the mains power cable, but as soon as I try to switch over to the USB cable, the phone resets and it again gets locked into the perpetual reset cycle.
Please help me!! Any ideas are appreciated.
Gavin.
Hi,
Found this: http://forum.xda-developers.com/showpost.php?p=1216580&postcount=23
Seems like a similar problem. He solved it by replacing the battery. Is it possbile to destroy a battery while flashing a ROM?

Same problem again:

Wow 40 views, and not a single idea?
Well I think I'm going to invest in a cradle, so that I can have both mains power and a usb connection, hopefully I'll be able to reflash with this. Anyone have expereince with this method? What is a good cradle?

[HELP] Strange Soft Brick issue

Hello all,
I searched around, but didn't find anything quite like my issue so figured I'd create a new thread.
I work for a company that uses Galaxy Tabs for various purposes. One of our men brought back their VZW Galaxy Tab (SCH-i800) and it was in an infinite boot loop.
I went to recovery and attempted to do a full wipe. This did not work (partitions were all jacked up) so I couldn't get it fixed. I'm not sure if the guy tried to root the thing and broke it or what.
Anyway, I was attempting to root then fix the partitions (then was going to flash a stock unrooted rom) and ended up soft bricking it (Phone Icon -- /!\ -- Computer Icon). The issue I'm having is the only time that screen comes up is when the device is plugged into the wall. It turns on, then off, then on, then off. If I unplug the device, it shuts down with no way of bringing it back up. I've tried holding power for 5 minutes, the same amount of time with power + vol up and power + vol down. Plugging it into the computer's USB ports does not help either.
It's like the battery is drained but it won't charge when it's on the soft brick screen. I've had it plugged in to the wall for almost 6 hours now with no hope in sight. When it's plugged in, I feel heat on the back of the device like it would normally be charging. The AC adapter is also the standard warmth after a lengthy charge.
I was wondering if anybody has had similar issues with this device and if there is any way to correct it.
--- EDIT 8/10/2012 ---
Another thing of note is when the device is charging, I can power it down by holding power for a few seconds, but the Soft Brick screen pops back up almost immediately upon release of the button.
I cannot boot into recovery or the standard download mode even when it's plugged in.
As long as you can get the Phone ! PC screen, your'e good, because this screen IS as a download screen. Go to this screen and flash a known good ROM.

You must not have read the whole thing. Not a problem.
The only time I get the Phone ! PC screen is when it's plugged in to the wall. As soon as I unplug it, it goes away and the device won't start up no matter what I try.
When you connect the tab to the pc, is it recognized by Odin.

No... When the device is unplugged from the wall it is shut down and won't boot back to the download screen, recovery, nothing. It doesn't turn on. There are occasions where the download screen stays up but it appears to just be frozen. The computer doesn't recognize it and neither does Odin.
I left it plugged in when I left work on Friday... Going to see if charging for the weekend does anything.

No dice.. still jacked.
I determined the following scenarios may have happened:
1) The battery died (bad battery) during a software update and messed up the partitions
2) The battery died (bad battery) while he attempted to (unauthorized) root or flash the device, messing up the partitions.
The only thing I'm sure of is the battery is fried so any kind of hacking I can do to the device are for naught. I was able to get it to connect to Odin this morning for about 3 minutes (after having it plugged in to the wall all weekend). During the flash it shut down again bricking it even worse. Now the device won't turn on when plugged in to the wall.
Thanks for the suggestions and help. I'm calling this a lost cause at this point. We're just swapping out the device for a new one. Once that's complete, I may tear the device down and try to do a reset on the main board to see if that does anything, though I doubt that's the case.
Right I had exactly the same problem as you (exactly the same symptoms) but I have now fixed my tablet.
Like you I got to the point where the Tablet had enough charge to actually unplug it and connect it to my PC where I then tried to flash a stock ROM using Odin. About three quarters of the way through flashing the stock ROM the tablet died, disconnected from Odin and I got a message in the task list in Odin advising me that the process had failed. Even weirder my PC did an emergency shut down and restarted in safe mode.
Anyway I tried it again but when I started my machine, once I'd logged onto my desktop I started up Odin as quickly as possibly, selected the .tar file and pressed start as quickly as possible....it worked and my tablet was flashed with a stock ROM. However my battery was still pretty much dead and the first time of charging once it had been flashed with the ROM took about 24hrs plugged in at a mains charger for the battery to reach 100%.
My point is persevere with it and you will fix it. I was at the point where I was about to send it off to be un-bricked but obviously I'm glad I didn't now.
It is a ***** of a brick though, this 'coma brick'.
I've been having these same issue with my friends i800 galaxy tab. Can you chime in and offer some advice?

same problem-solved
I was having the exact same issue. the device screen was completely black when plugged into the computer. I was just about to give up when, all of a sudden the device went to the boot error screen while plugged into my computer. Apparently, it must remain plugged into the computer for about 20-30 minutes. Once this screen appeared, I ran the Heimdall one-click unbrick utility, and like magic, my galaxy tab was working again. Give it a try, and good luck.

Phone not charging, Shuts off when plugged in, various other issues.

I am on stock everything except for recovery, I would like to bring my phone into Verizon to get it replaced because of my myriad of issues, but I am unable to install stock recovery. These are my issues:
1.) Phone is not charging, I have tried the original charger + cable, and at least 5 others, nothing is working. I can boot the phone and use it but its stuck at 0% (sometimes it goes up to 2% but never higher)
2.)Whenever I plug the phone into a power source or to the PC it shuts off and restarts
3.) I cannot get into download mode to install the drivers, I hold VOLUP and then plug in the cable, and it says download mode, but then it shuts off again and gets stuck in a bootloop until i unplug the phone, and then power it up without the cable in it. Which is an issue considering the battery never goes above 2%
4.) Phone is in near-perfect condition, minimal cosmetic damage and no scratches on the screen. So it cant be accidental damage.
anyone have any suggestions? I would just take it into verizon but i have TWRP recovery, and im afraid they will charge me if they find out.

M7 charges for 20 seconds then stops charging

Dear XDA,
I have a fairly annoying problem. The phone is not charging properly.
When i connect my phone to a charger it charges for roughly 20 seconds. Usually it doesnt show anyting at the start. But after a while it shows the charging icon on the display and the led starts blinking. After 20 seconds it stops doing that and after a while it shows the charging icon + blinking led again. Somehow it's in a charging loop.
I've tried different adapters. Different cables. Let it 'charge' overnight. And hook it on to a computer for a hour or so.
Sometimes i can turn my phone on but then it's on 1% and powers off emediatly. It won't charge when it's turned on.
I'm running MaximusHD 46. I have it for a while now and had no problems whatsoever.
The phone is from the Netherlands but I live now in Zanzibar. They have a different power output and the voltage is not stable. Usually i charge it when there is a stabilizer connected. But hasn't been always the case. Could that be the problem?
Thanks in advanced for your replies,
Lennard

This problem occurs all the time? I mean it's the same in all modes like when booted up and running Android, while powered off and while in recovery.
Or only when the device is powered off?
What recovery are you using ? (name and version) please :good:

I have not been able to get into recovery. Basically it's dead in the water and occasionally i can turn it on.
The recovery i use is TWRP. The version i'm not sure of (since i cannot check) but if I think it's 2.6.3.6.

Sounds like a Hardware problem either with the usb port or the battery itself.
A new usb cable may help if you've already tried that there's not much else you can do.
Some of the newer 2.8.x.x versions of TWRP have issues charging while off. But it doesn't effect charging any other time. Have you tried powering on while it's connected t an AC wall charger?

I've tried multiple usb cables and chargers . Also I tried to turn it on while connected to a wall charger, even recovery doesnt seem to work. Yesterday I still could turn it on. But today not ..
Ugh, sounds like I have to buy a new phone
You have checked the usb port for dust and lint yeah?

Lint? What do you mean with that? But yeah, I have cleaned the usb port from dust.
And I managed to get into recovery! I tried finding out where i could reset the battery settings... but I couldn't find it . The phone was getting hot so i think it's sort of charging in recovery mode. So i let it be in recovery mode for the charging. Let's see if that works :]

If you can get a little charge in the battery you can try the USB Host Mode reset. Power off the device and hold Volume up+Volume Down+Power. Hold all three buttons for 2mins plus. The device will appear to bootloop while your holding the buttons. That's normal. When you let go the phone should boot up normally.
Test the charging again :good:

Thanks! That might do it. Anyway i'll try it this afternoon when i'm back home. Should I keep the phone connected to the charger or disconnect?

I suppose it would be best to disconnect during the reset procedure. But I don't no for sure if it will make any difference connected or not.

1st Gen Moto X Charging Issue...

Thanks in advance for anyone's advice and or help... My Moto X is stock/unrooted. When I plug it in to charge (yes with the original charger) l noticed the lightning bolt icon does not come on. However, it would originally still charge. Now when I plug it in, no lightning bolt, no charge. To charge it I have to reboot without being plugged in and then plug it in after reboot is complete. If I unplug it and plug it right back in... No charge. I would have to reboot. Here is the kicker... I did a full blown factory reset. And it did not fix anything. One would think it is a hardware issue... But if so why does it charge every time without fail after I reboot??? That sounds like a software issue right??
I am perplexed to say the least. Does anyone have any ideas on how to fix this issue. Also if I reboot with the power cord plugged in I get caught in this restart loop where is shows the boot image and shows its charging... Please down and repeats?? I need help!!!
Thanks!!!

Try with a different charger and cable.It's very long to explain, but it's probably related to the battery protection kicking in. I would put my money on defective charger, but not entirely.
