hi am trying to restock my galaxy tab GT-P1000, but i cant charge the battery passed 10%... i left the phone charging overnite, switched off, using the official tab charger & cable with no joy... i hoped it was just reporting the wrong percentage so i started the overcome guide to restock...
once i got to the stage where the phone should reboot and give me the sexy voice reporting that it is converting the file system i hear the sexy voice say something like "no battery level conversion cancelled, no battery level conversion cancelled"
what does this mean ?? i cant get a battery level as i cant charge, so how do i get around this catch 22 ?
i have wiped the battery stats in CWM and i was going to use a market recalibration app.. but phone needs to be rooted... and of course i cant get back to rooted with converting... ARGH...
someone, anyone please help
how do i fix this ?
thanks
Need to fix this for a friend...
He made some mistake or odin failed or smth when he tried to root.. not sure.. but download mode was working still..
No Problem I thought and told him to bring it over - but when I flashed the stock rom, odin failed again.. no problem still I thought.. happens and I'll look for another rom or a pit etc..
But then when I restarted it into download mode, it just turned off after a few secs and hasnt been turning on since then.
I'm guessing the battery is empty, since it wasnt charging for a while .. (kernel broken so it doesnt even charge when completely turned off..)
So I need to find a way to charge the battery, a new one costs like 40 or 50 euros and I would like to avoid buying one.. just to be able to get the thing into download mode again to fix the software..
Anyone know how to charge Tablet batteries externally? I already opened up the tablet and exposed the battery, but I know charging Li-Ion is difficult (if possible at all, without special equipment.) so I need some help please.
Hello, my friends,
Greetings from a old timer. I am a Nexus 5 user and my OS is 5.1.1
I have a LG Adaptor and I have a LG Cable to charge my phone.
Last night when I was plugging in my phone (I was quite sleepy), I saw (or I think I saw) the following:
- A charging ICON (saying Speed or Fast or something like that) and a 15% number
- On touching that pop up it vanished
Has anyone ever seen that ? I am trying to reproduce that and I am failing.
I have a factory build LMY48B and the Baseband version is M8974A-2.0.50.2.26
Please, can someone shed some light or was I seeing things ?
I just connected my charger cable to charger and the other side to the Nexus 5. Properly, I might add.
Thanks and best wishes

after I upgrade my Note Edge on 6.0.1 OTA ( on the Air )
Ive turned off Location History, S-pen detection , and buy new battery to improve battery life
But, my phone got message ( couldn't use fingerprint after restart ) when im trying to used my phone
After i turn it off ( sleep )
- Phone cant be turned on immediately after I turned it off
then after a while I got this message ( couldnt start boot normally, ddi : mmc_read failed )
Any help ? about what might be happening ?
PS : Im trying to downgrade it to KK 4.4 but had no luck on rooting the device.
Any HELP appreciated. TQ
ps : green light with screen off blinking atm..
no simcard nor external sdcard installed
If you want to downgrade to kitkat try flashing stock firmware from manufacturer site
any link ? tks... and do umthink its the hardware issye or the software issue ?
It's probably software, not big deal.
It's better that you google it but search exact model you have that in 'About phone' or on box in which phone was when you bought it.
And just one more thing did you cleared cache after upgrade? Also factory reset would probably clean up the mess, than you'll probably could use phone with marshmallow on it normally.
tq, but we are suspecting the nvram...because off the symptoms and the excess heat.
and yes ive have wiped cache then factory reset it.
seniors, do u have any experienced IF the problem was NVRAM and it was replaced, will it last ? thx
Apparently the problems was the battery, Samsung Note Edges are very picky about the battery, even when I 've replaced the battery with new battery . Apparenty in my case the battery was not super ORI ( even since ive bought the batt with distributor logo on it ) with the same voltage and not even swollen.
nope, not the battery, im thinking of mainboard / ic power defect. since the battery cannot be recharged after forced shutdown
hello,
I have a Samsung S2 PLUS GT-I9105P (4.4.2 stock) at the beginning it started by turning off whenever I plug it into power. I started buy doing what all I can find in the internet ( stick a needle on the hole, factory reset, changed battery). NOTHING worked.
Then, since it never been flashed I tried 2 costom roms then nothing, still the same problem....and after than, I bought a new connector but this time the problem changed. the phone keeps charging and discharging even if it's not plugged (all the time the charge symbole flashes).
The last thing I did is that I disconnected the port from the motherboard and still the symbol whenever I insert the battery... I started to think that it doesn't come from the connector.
Please any ideas? Thansk in advance

4.4.2 stock but i switched now to cyanogenmod 12.1.... it was working fine but i charged it for like 30mins and when i unplugged it it started doing it. Then, I factory reset it and I didnt plug it to the wall and for now it still working... I think im gonna let it dry until it turns off
Replace the whole pcb board where the charging connector is. On this board is located the power controller chip and maybe it is faulty. It is cheap: https://www.aliexpress.com/item/For...lgo_pvid=ecea0e18-0699-4492-9a81-6b08569c2766
First. S2 plus does NOT have 4.4.2 android STOCK (except if it is a custom rom, then yes)
Secondly, you need the replace the charging IC
I did replace the Dock Connector. I will send it for a replacement of the charging IC.
keep u posted guys. Thank you all
