Hey guys, last night something happened to my good old S2, i had problems about it's battery before so when it's battery suddenly dropped down from %20 to %0, i wasn't surprised. So i went and put it to charge (i don't use the original charger, i found a huawei charger and it gets the job done) and after a moment it showed that it is at %50 battery (like i said my battery has some problems), so i tried to turn on my phone. Then it went in a boot loop on the Samsung logo, i was going to turn off the phone so i can clear the cache partition so i unplugged the charger cable and it suddenly went dark, no power, no nothing. I tried to put it on charger again but it didn't help. I let it charge there overnight but it didn't help either. Then i borrowed my friend's S2 battery and it didn't work while my battery powered up his phone so i think problem is not on the battery. What do you think, is my phone bricked/fried? I had a photo archive in my usb storage(not in the SD storage) so i really wantt to recover it if its possible in anyway. Your help will be greatly appreciated. Thanks..
Thats wierd , try with another charger and the original battery and let us know how it went.
PS:That phone is a though piece of hardware mine is still runing (of course after a lot of repairings and software changes) after 5 years , finally swtiched for lg g3 used from ebay , best deal ever

I tried another charger adapter (not original, my original charger is not working properly) with different cables and it didn't work. And for the battery, i have an original battery and it didn't work, then i used my friend's non-original battery and it didn't work either like i said before. But my messed up battery turned on his S2. So the problem is probably not on the battery.

No, pc doesn't indicate anything that my phone is connected nor the phone shows "charging" indicator.

Hi there. I has a similar problem, the phone was working but even with the orginal charger plugged in was not charging at all (connection to PC didn't help either).
There is a procedure to "retrigger" a stuck charger IC.. I lost a link to it and I'm looking.
Had something to do like:
_ remove battery
_ plug phone to charger
_ insert battery
_ turn on
After that I'm not sure anymore.. maybe again "remove battery" step. After that put everything to rest, insert battery and then the charger and see if it works.
I'm googling, someone made a post on XDA with the full instructions.

Ok thanks please let me know if you find the full procedure and I'll try it
Hi, I found the procedue, it's exacly how I described the 4 steps above (the source it's on a external forum, I'm not sure if I can link it here - I'll send you a PM if you like).
SO, if the phone was stuck just like mine, working until the battery discharged even if plugged-in, that will solve it quickly (mine did precisely).
Otherwise.. there could be several reasons why the phone is not recognized anymore, some point out a faulty cap around the charging IC (if the phone is totally dead):

This cap, if faulty, is actively shorting "Vbat - Gnd" line thus prventing any operation of the phone. Could be water damage o defective charger. It depends how much you want to dig to repair your phone (there could be 1000s other reasons - this is the most HW one).
From what you described the problem in your post.. this defective Cap would/could explain many things.
How are your soldering skills? First thing I'll do is to open the phone and inspect, possibily with the help of a multimeter, next desolder the cap and power the phone back with a charged battery (don't connect the external charger, there might be burned pcb traces - but that's anohter story).

Sadly the first procedure didn't work. My soldering skills are not that good but i might know someone who can open up the phone and do things properly Do you know any detailed instructions for the second method you mentioned? Thanks..
I've no other details other that the picture. Before tearing the phone apart, you should try to test "continuity" beteween the "+" and "-" metal contacts of the battery holder. If you have a friends with a multimeter he will know how/what to look for (tell him about the short).

So, let me start
Few weeks ago my phone hard-bricked when i was trying my softbricked (Rom manager fault) O1 unbrick with KDZ. But it is just the start. So my phone was left at service to unbrick it for almost two weeks. When i got my phone , it was running some 2.2 official ROM, but it was strange, filled up with russian applications and widgets. I didn't liked that, so i updated my optimus to 2.3.x (The newest version, but don't remember which) to have the new baseband. Then with super one click rooted, and through terminal i installed CWM (5.0.2.0). Then flashed the newest oxygen. My phone was very unstable. It was just shutting down for no reason, restarting, (and i also got two times kernel panic, when it was clocked just to 748mHz) especially when i was using it. Also battery lasted not long, so i wiped batery stats, but it not helped. So i decided to flash new ROM. I fully wiped everything, and flashed PerfectPeso 2.2. Then flashed fixed scripts, GAPPS, New kernel. IT was also VERY unstable, so i thought old version PerfectPeso is not compatible with new kernel (PP.kernel v1.7), so again i wiped everything and flashed PP 2.3, then GAPPS, new Kernel, Fixed scripts. It was still not stable as it should be.. In the morning phone was just turned off, so i turned it on. In battery stats there were strange things: battery just came down 10 percents as i turned it on, and also it doesn't showed it was turned off at night not all. Phone was connected to charger all night. In a day it was just keeping shutting down, but just then, when the screen was turned on. After that, when i came home, it just turned off, and not turned on, even no LG logo when trying to turn it on (It turned off in my hands, when 20% batt were left). So i just kept trying to turn it on, by removing batt, reconnecting the charger. AND IT TRUNED ON !! but after few moments it went down again. I started trying again to turned it on, it turned on again, just in few attempt's. My phone was showing that 23 percents still were left... So i fully charged it, when i did that i tried to calibrate battery, like the manual said (i typed in su, then calibrate into terminal) but calibrator said i have to turn my phone off, and when it boots, i have to remove batt, and then put it in. I did it few times (with the calibrator help). I thought everything is fine. (But i wanted more performance, so i made EXT2 in my SD, then tried to enable ungaze a2sd by typying into terminal A2SD, but nothing hapened. Then, i tried To ZIPALIGN all APK's Manually, by commands: "su", and then "zpall". The command did something, no errors. Then i wanted to get rid of boot logo by trettet, because it not looked very good, so i went to Settings and disabled my bootlogo. Then i just started playing gta III (now phone was only on default cpu clock speed, because i disabled overclocking on boot, and turned it on when i needed it). Then I pressed home key, opened Dolphin browser, and my phone went down (as usual). Then tried to turn it on, but no signs of life, i did it for over 20 times, but still no luck from yesterday. Can anyone help me to solve this ?
Also, i don't think it is fully bricked, because when i connecting the charger to my phone, phone battery pins gives me around 2.35 V (but when it was full bricked few weeks ago, it gave me no voltage)
Thank you
p.s. sorry for my terrible English
ahaha yes very funny (sarcasm) -.-
Cool story bro..
Can anyone test full-bricked device, what voltage comes to battery pins, when phone is plugged to charger ?
Thanks for the changed name )

I just wanted to know what voltages comes to the battery, (or should come if it is not removed) in the phone ;DD
Anyways, thanks for making me happier )
But i still need to know, how to test if my phone is really bricked :/. I know, it sounds a little bit strange, but i can't explain everything in English because of the lack of knowledge of English words ;DD

Then how another time it didn't show any logo, but after trying it booted up. Also how it could brick, only by opening browser ? (then my phone went down and won't turn on)

Well, you can have hard brick or soft brick...
If it has a hardware brick, it is unknown how will it react, best to go to a service...
If it is software brick, try flash stock GB with kdz... if not then it is bricked, go to a service center...

I know. And also, today i thought that i could try to trun it on, so i took the phone, tried to turn on, but nothing. Then I took the battery out, shaked my phone and "Clapped" it into my leg, inserted the battery, pressed on button and.. the phone showed LG logo !!!
Then it went down, then I plugged in the charger. It charged a for few min. Then i powered on my phone, it turned on succesfully, so i just layed the phone on the table, to charge (It was 4% at the time). After few mi. i took the phone and it was turned off. I tried to turn it on, but no signs of life. So again, my phone is "dead". It is no truning on anymore, and shaking, pulling batt out doesn't seem to help. What should i do ?

?
so, another thing: The phone in yesterday evening started working normally (Exept few turn-offs), i left it charging till this morning. In morning phone was not active, i turned it on by reinserting batt, but phone showed just 75% batt left, even if it was plugged in whole night. Can anyone help me to remove all this sh*t ?
Also I tried few ROMs, but same. Maybe KDZ would help me if it is baseband problem ?
Or maybe it is hardware problem ?
I would be very happy if someone could help me with this
(last time KDZ bricked my phone, so i don't want to use it anymore)

Also it is happening only with sim, never experienced it without sim somehow...
Hi. I’m having a problem with my Samsung Galaxy S2 I9100 (actually the I9100M, with Bell Mobility in Canada). I’ll try to be as detailed as I can.
I unfortunately had the phone in my pocket, and went into salt water (the ocean) for about 5 minutes. I realized it was there, and took the back case and the battery out. But I did not do anything else. About a month later, after sending it back to Bell and hearing I couldn’t get warranty, I decided to take a look myself.
I took the phone apart, and used 99% alcohol and a cotton swab and wiped everything down. After letting it dry for a day, I turned it on and it worked, nearly perfectly. The screen’s color is fine, the speaker works, the microphone works, the internet works, SIM card, making calls, Wi-Fi, etc… So I was quite happy.
However, I quickly found out that there is a problem somewhere with the USB connection. (Or, so I thought) When I plug in the USB to power the phone, nothing happens. It is not recognized by the computer, nor does it show that it is charging. So after going to a cell phone repair shop and speaking with someone, they said the cheapest thing would be to replace the entire USB Flex cable (incl. microphone, etc). So I bought one for $25 brand new (which I later realized I could’ve gotten cheaper, but I digress), and then went home, opened it up, took out the old one, and put in the new one. And sure enough, it did NOT fix the problem.
However, the “weird” thing, is that if I turn the phone off, and then plug in the USB connection, it then powers up and shows it is charging. (So obviously the “connection” works, and I mean, it is a brand new USB flex board, or whatever it’s called) But as I sat there, I noticed it is NOT charging… (Even though the battery indicator shows that it is charging, and the About Phone setting states this as well) And as well, the computer still does not even recognize that it’s plugged in.
So, I’m really at a loss for words here. I replaced the part, and obviously there is another issue. So the main points are:
Battery (which is brand new) does not charge when I plug in the USB connection to either a computer or the wall plug-in.
If the phone is on and I plug in the USB, it does NOT recognize it.
If the phone is off and I plug in the USB, it turns the phone on, and states it is charging, but does NOT charge. And the phone is NOT recognized by the PC if I have it plugged in.
If anyone has any ideas on what I can do, please let me know. There is still a lot of corrosion inside, but I’m not sure how much more I can get at. I assume that the problem must lie with the mainboard, where the USB flex cable connects to, but before I do anything else, I wanted to see if anyone had anything I could try. I hope I explained it well above. Please note, the phone works PERFECTLY aside from this (and some minor blurriness on the camera, probably the lens is dirty).
Is there a test I can run to see what the issue is? Clearly the connection does work, otherwise the phone wouldn’t recognize the USB and turn on by itself when I plug the USB in. But I’m just looking to know 1) why the battery does not charge when the USB is plugged in, and 2) why the PC does not recognize the connection.
Thanks so much in advance,
Much appreciated.
I had the same issue with i9000
Hi Alex,
I have the same problem with my SGS.
The only difference is that I do not know how/why it happened. I was hiking in the snow and kept the phone in my packet. At home I put it on the AC charger and like 20 min. later it started to vibrate (like in case of software problems). Since that time the USB connection shows the same symptoms as yours.
Official service suggested the replacement of the motherboard. I do not need to tell you that it would cost 50% of the price of a new phone...
So I bought an external charger for something like 10 EUR and everything is fine.
-I use the external charger to charge the additional battery I bought and replace it when the other one is running low.
-I use the external SD + BT or WiFi to transfer files
-Since the phone was already rooted I use mobile Odin for updates
Not a perfect solution but at least I got a workaround for everything for a minimal cost.

That is a solution but not the optimum one.
Assuming the warranty does not cover for water damages, its better having the charging port replaced. Chances are this might fix it.
i think take it service an get it repaird,cause as the main board has corrussion..good luck
Went fishing with some friends last month and a mate dropped his in salt water as well. I popped it into a cup of fresh water to rinse out the salt and pulled it apart completely.
After about an hour put it back together and worked fine, except for the charging port and battery. A fresh battery and it now runs fine again.

I'm interested in finding out more about this too - I think I may have damage from humidity?
Have been in fiji for a week.
While I was there I had the similar symptoms:
Thinking it's in car mode occasionally, or thinking its charging when not plugged in, and discharging when plugged in. Very weird.
Now that i'm back home, I've tried different usb and power cables, and they all give the same result of not turning on but occasionally giving me this screen:
http://i.imgur.com/l5BjA.jpg
A different battery (I had an 2000mah sized one and a stock one) is working but not charging at all so I turned it off quickly after that.
This makes me think it may be humidity damage from the trip, but it hasn't been in water or treated badly.
samsung galaxy s2 water damage help please!
Hi please help if you can any suggestions are appreciated!
My brand new (as in three days old!) samsung galaxy s2 got some vodka and coke spilt on it, I took it all apart dried the excess off then left it in rice for a week. When I put it back together it wouldn't turn on so I decided to try charge it as it had already been low battery when it got damaged. It's been charging for around five hours with absolutely nothing happening then all of a sudden this message has appeared on the top left side of the screen: LOW BATTERY!! CAN'T DOWNLOAD!!
I have no idea what this means as it hasn't been on for a week and I am crap with phones.
Does anyone know what to do or why it's done this please? Really don't want to claim as I have already 4 times!
Please help! thank you
Crap I dunked my phone on a soda/vodka drink. Phone kept working. I was rather surprised. Didn't think much of it.
The next day I checked to make sure that the phone will charge, it does. I connect it to the PC, and it fails to get recognized. Wow Just realized that any data saved on the internal USB is probably out of reach. I can move it or copy it to external SD and get my stuff.
This makes a good case why NOT buy phones without External SD Cards.
Wow, I'm a little sad. Just a little.
anything i can do besides specialized service
I spilled just a drop of Pepsi on my GT-N7000 and after drying it with a towel(i didn't think there was much dmg) i tryed to put it to charge as it told me the battery is at 10%,so i leave him charge for like 2-3 hours,and when i removed the charger he got stuck in a charging loop,showing me the sign of charging on the battery and after 2-3 seconds,disappearing and so on,also if i try to shut down the phone,it shuts down but right after that the battery charging icon pops on and off making the phone shut down for good and again again in a loop,making me remove the battery for total shut down,after that,i opened him up and saw that there are some drops of juice near the micro usb hole,so i took some ear cleaners and cleaned all that mess up,dried the zone with a hair dryer carefully not to melt something, assembled him back and still no sign of recovery,also i didn't use any alcohol in the cleaning process,just the dry ear cleaners.... :crying::crying::crying::crying::crying: besides all that the phone works fine...

Trying to charge a device which probably got some liquid into it, very bad idea.
Guidelines for next time:
1 . Switch of immediately and remove battery.
2. Keep in rice or someplace safe to dry.
3 . Use after couple of hours

I took the N7000 to a service and the guy had to change to USB port because it got oxidated,so problem solved,i have to take big care next time where i keep my **** and liquids
Why should we care ? This is SGSII Q&A. And even tho telling people to do this has started to get old over the past few days....
Post to the correct forum for your device
And to you boneheads who encourage this by helping people who do it, stop. Now.
Hi Alex,
I have exactly the same problem and I wonder if you solve it? I'm also thinking to buy new USB Flex cable, but not sure if would fix the problem.

Don't use „ETHANOL", use that so-called „ISOPROPANÔL/ISOPROPÝL“ - Alcohol. 90% is enough but higher is better.

The screen’s color is fine, the speaker works, the microphone works, the internet works, SIM card, making calls, Wi-Fi, etc… So I was quite happy.
However, I quickly found out that there is a problem somewhere with the USB connection. (Or, so I thought) When I plug in the USB to power the phone, nothing happens. It is not recognized by the computer, nor does it show that it is charging. So after going to a cell phone repair shop and speaking with someone, they said the cheapest thing would be to replace the entire USB Flex cable (incl. microphone, etc). So I bought one for $25 brand new (which I later realized I could’ve gotten cheaper, but I digress), and then went home, opened it up, took out the old one, and put in the new one. And sure enough, it did NOT fix the problem.
However, the “weird” thing, is that if I turn the phone off, and then plug in the USB connection, it then powers up and shows it is charging. (So obviously the “connection” works, and I mean, it is a brand new USB flex board, or whatever it’s called) But as I sat there, I noticed it is NOT charging… (Even though the battery indicator shows that it is charging, and the About Phone setting states this as well) And as well, the computer still does not even recognize that it’s plugged in.
So, I’m really at a loss for words here. I replaced the part, and obviously there is another issue. So the main points are:
Battery (which is brand new) does not charge when I plug in the USB connection to either a computer or the wall plug-in.
If the phone is on and I plug in the USB, it does NOT recognize it.
If the phone is off and I plug in the USB, it turns the phone on, and states it is charging, but does NOT charge. And the phone is NOT recognized by the PC if I have it plugged in.
If anyone has any ideas on what I can do, please let me know. There is still a lot of corrosion inside, but I’m not sure how much more I can get at. I assume that the problem must lie with the mainboard, where the USB flex cable connects to, but before I do anything else, I wanted to see if anyone had anything I could try. I hope I explained it well above. Please note, the phone works PERFECTLY aside from this (and some minor blurriness on the camera, probably the lens is dirty).
Is there a test I can run to see what the issue is? Clearly the connection does work, otherwise the phone wouldn’t recognize the USB and turn on by itself when I plug the USB in. But I’m just looking to know 1) why the battery does not charge when the USB is plugged in, and 2) why the PC does not recognize the connection.
Thanks so much in advance,
Much appreciated.

Hey,
Major issue I'm facing today. I first noticed this about 2 days ago, I'm currently running Resurrection Remix 2.0 and has been installed for about a week? with no issues.
Two days ago, I put my phone on to charge at night, as usual. Woke up the next morning and by mid morning Noticed my battery was at 15%, When I checked the battery stats, It looked as If the battery had not charged ( I'm pretty sure it had been on charge, but put it down to the fact that It wasnt plugged in correctly)
Next Day, (last night) I put it on charge, and checked it was definitely on charge, which it was. I woke up this morning to find the exact problem, this time at 50%, When I remove the power cable the charging animation still continues.
I turn the power off, Remove the battery and wipe battery stats and start back up, over the next 20 minutes the battery stats increase my battery percentage (not charging) and then continue to drop later on.
Tonight my phone had drained its battery, thought it would be best to drain it, leave it off on charge and turn it back on. I've come to turn it back on removed the power cable and now it will not turn on but constantly loop through the Charging animation icons..
Does anyone know the fault for this or even a fix? I cant boot into my rom, or even CWM
urgent help needed!! thanks in advance

Do you have a screen shot of the battery usage? And it sounds like you have an issue with the charging port. Clean it with a dry toothbrush
Sent from my GT-P7510 using xda premium
may be a kernel change would also help u ...
Pretty straightforward really. Either a battery problem (less likely) or a problem with the USB/charging circuitry (more likely; we see it on here all the time).
Try another battery & see if you can get the phone to boot. Otherwise, service centre.
As KMs said, you might as well clean the USB port while you're at it, and then try a new battery (at least you'll have a spare when you get it back from repair).

Okay tried cleaning it with a tooth brush but no luck, the phones been playing up all day, still saying its charging even though Its not plugged in lol. Just got back home to back everything up do a full wipe and update the rom to the latest version+ kernel and its not even being recognised by USB, it'll charge, but not recognise
Is this a common problem with the S2 then? that the usb fails/malfunctions?
Think I'm gonna have to take it back to three on Monday, hopefully get it repaired/replaced asap ( but will need to flash back to original stock ROM + Kernel first!)
We've seen our share (I've seen at least a couple of dozen) of these in Q&A over the time I've been here (~8 mths), yeah.

Cheers, Thanks for your Help. I'll let you know the outcome on Monday.
no point starting a new thread.
So Does anyone Know where I can get the original (HG3) Three UK ROM for Samsung Galaxy S2?
I don't want Three to say that because I've put a custom ROM on it I've voided my warranty
Here, Samfirmware.com or you can get the latest firmware for phone model/country/carrier that you'd normally get via OTA update with the PC version of Checkfus (search for it on here/Google).
Thanks again for all your help.
finally got some screen shots off my phone,
here's the battery stats if anyone's interested

Downloaded the firmware, however I cant seem to find how to update OTA, Its given me a .tar which I could use Odin to upgrade, However as I cant get it to read from USB I cannot get Odin to detect my device
That's probably due to the USB circuitry problems you seem to be having. Might want to use Mobile Odin (get it from Google Play) to flash the firmware. If it's an ICS stock rom, you should be able to use Triangle Away to reset the flash counter.
Hey guys..im also experiencing the same problem.....sometimes charging stopped halfway....when i check with the "battery widget" it says overvoltage (with " ! " symbol)....
is it because the firmware problem or usb port or charger problem ? any solution? Tq in advance guys !
Did you even bother to read the thread ? Go back to stock & see if this resolves the problem. Then clean the USB port with an unused toothbrush or similar. Try a new battery. Try a new charger. And if none of these fixes things, service centre.

Hi guys.
Just now I was trying to use my phone and suddenly it couldn't turn on anymore. I searched around in the internet and found out that it might be the problem of motherboard.
It doesn't turn on at all. So I am wondering if I change my motherboard, will the data inside be wiped too?
I am okay with the apps and stuff but I don't want to lose the pictures, contacts and my texts.
Any idea on what I can do ?
I really really really don't want to lose those 3 things mentioned.
Thank you a lot for any replies
What (if anything) did you do to resurrect your phone?
Did you remove the battery for some minutes?
Did you try turning it on with the help of a USB Jig?
Does the phone charge?

As far as I know the memory is part of the MBO so if it gets replaced the memory gets replaced too, hence all data not on external SD will be lost.

I did remove the battery for about an hour. Charged with and without battery on. No response both ways. I don't own an USB Jig so I didn't try that method. I am using official ROM, most probably 4.0.4 ICS. Any clues ?

What I was trying to say is: does the battery get charged, i.e. if you connect the AC adapter to your phone (which is turned off and has the battery inserted) do hear a sound and do you see the battery charging symbol? If not, how can you tell that the battery is charged at all? First of all you should make absolutely sure your battery is fully charged, for instance by putting it in an other phone.
Once you know the battery is fully charged the Jig might help. You should also try getting into download mode by using Volume Down + Home + Power button. But again: first make sure the battery is charged.

I used two different charger and tried to charge the phone and nothing came out on the screen. No battery charging symbol. It remains the same dark screen. I will try to find another phone or battery that can fit to test, most probably at the stores tomorrow. But I am pretty sure my battery have some batteries left. If so, anything I can do right now ? It doesn't switch on at all so I guess that's why the download mode didn't work ? Is there a big possibility of it being the motherboard ? I don't mind replacing anything but I just don't want to lose those important data. Thanks for the help
Can you get into download mode? Use the volume down + home + power button combination.

Without Jig? No. Probably order one from Ebay? The Jig is quite cheap so you do not loose much money if it does not work.

I don't know, sorry. See my first post concerning MBO replacement.
Thanks a lot. I will see what I can do at the stores later Hope it's not the motherboard problem. If not I guess I have to lose all the data.

Hey!
I had a PiPo M9 (WiFi) now for about 2-3 weeks and everything worked perfectly.
No problems with rooting and installing ROMS ( i fixed that 2-3 days after i bought it)
I was playing some angry birds yesterday, and all of sudden i had VERY low battery, i put it on charge even if i recently took it from it.
Then i noticed that the DC-connection in my tablet is "loose" , i needed to have the cable in a specific position for make it charge.
Battery was fully charged but it said i had about 16 minutes left, and in 1 minute it dropped to 43% and only had 2 minutes of the battery left...
I tried to calibrate the battery after it was fully charged (i let it charge for almost 10 hours) but there was no difference...
Anyways... i played some games later on and forgot about the position of the cable so the tablet died...It had a bootloop about 6 times and i was trying to put the cable correct for make it charge but i failed and the tablet died.
Now it doesnt react at all, and unfortunally i don't know what the EXACTLY position is for the cable so i have been trying around but without success...
When i am connecting the USB to the computer it doens't react either, and i tried to push in RESET while holding the other buttoms as well, without success...
I Don't know what to do , and i don't know what is wrong?
I opened up my tablet carefully to see if i could see the problem but it is hard to do anything without knowledge about it....
I know that it has something to do with the DC-connection but i can also imagine that it has something to do with the batteries..
If i need to change the batteries , what should i buy? And how should i do? I need a guide, walkthrough ,... i have been googling around , also on youtube, without any luck...
Anyone out there who can help me?

The red LED charging indicator should be lit when it's charging, so that should be your indicator if the cable is connected properly

.... But... That is weird...
If i am connecting the charger to the wall - it is glowing - before i am connecting the tablet.. so how should i know that it is actually charging correctly?
So, if i connect the charger to my tablet and it is NOT glowing , then wnat is wrong?
(In some positions it is not glowing...)
It is glowing however the tablet is connected or not... But how do i know it is charging?
I cannot turn it on, and the computer doesn't react either when connecting the USB.
Btw, the light on the tablet haven't been working for a few days either so i can not see fomr there...
Are you referring to the red LED on the charger itself? I was referring to red LED on the tablet. The red LED on the charger is always lit regardless of the status of the charge. The red LED on the tablet stays lit while it's charging and turn off when it's full (100%)
Yes, i am going after the charger and not the LED on the Tablet because the LED on the Tablet haven't been working the latest days...
It has been charging without the LED on, .. But now i can not see when it is charging while i am trying to move around the cable while being connected....
It seems like there's a problem in the battery circuitry or the battery itself. The red LED on the tablet should be lit while it's charging. Also when connecting the charger to the tablet while it's off, the screen should turn on for a few seconds, showing the Pipo logo and then the battery charging animation. Maybe you can also use this indication when trying to find the "correct" cable position.

But... How do i open up the tablet ? Is there a guide anywhere? And if i need to buy new batteries - which should i have?
And how to fix the battery circurity?
I've been trying with different positions and everything since it died, NOTHING is happening at all... No bootlogo, no batterylogo, no light... Nothing happens..
I am really appriciating your time, i feel really desperate hah
Well unfortunately, I don't have any idea how to open the tablet. Have you considered sending it for repair/replacement?

No since i already opened it up i destroyed my warranty
It will cost so much.. so i rather have it as a project... But like i said... Guide/walkthrough would help SO much..
If you know ANYTHING or maybe check around it would be a BIG help..
A girl like me never gives up, but even if i am a geek and nerd when it comes to computer/phone/tablet... i need help on this one..
Jah those pictures isn't much for help, better than nothing ofc but i can not go from that! =/
I'm confused, so now you've already opened the tablet? Maybe you can check first why the cable connection feels loose. Other than that, I don't think there's much that can be done by a typical end users like us
Yes, i mentioned that in the first post as well.
I opened it up already but i cannot see or touch anything because it looks like i need to open up the part from the screen as well...
I dont dare to do firthermore without guide or walkthrough.. =/
https://www.dropbox.com/sh/b3te9typrpamhdh/v8ad8clWis
I took some pictures of what i can see, but like i said - i don't dare to open up more than this without using a guide or walkthrough...
If you know more about it, please let me know!
I see nothing unusual with the DC port. Hopefully someone can guide you further with this

Well, since i haven't fully opened the tablet it is hard to se the connections on the other side, but indeed - it does look okey... It isn't moving either when i an connecting the cable... so either it is the batteries or the connection from the other side i guess..
I really hope someone can guide me through this, it is an interesting project while at the same time this tablet is my nr1 favorite at home atm haha
I've got the same problem. I don't want to open the tablet and break warranty. I think it's a problem with the dc connector.
I solded and fixed the DC-contact, it was loose, but there is a component missing and i am unsure what component it is, so i have a picture and hope someone can help me out....
I'm a little unsure of what component that is missing, but it is backside off the mainboard, just below the dc connection.

OK I am going nuts... I have two Pipo Max M9 Pro (s) and for the life of me I can't get my micro SD card to fit correctly in the TF slot. FIRST the slot is right on the top which seems dumb... An SD micro card should be somewhat recessed... And it just does not feel right.... Anyone cross this bridge with their Pipos....
