[Q] Which I777 Rom supports charging using a I9100 battery - AT&T Samsung Galaxy S II SGH-I777

Hello!! I have a I777 and my battery is almost dead and since I can't find a I777's battery on my country I was wondering if anyone can recommend me a rom (or Kernel) in which I can use and charge a 9100 baterry on my I777 without having the loop issue.
Thanks!!!

No rom/kernel package will be able to get around this hardware issue. You'll either have to make do with what you have or simply buy an i777 battery. They're really cheap ($5 or so), check in the Accessories forum for more info.

The $5 batteries are all fake, and are exactly the same as i9100 fake batteries. They don't have NFC.
i9100 battery is a fit and if you have a normal one - it should work without bootloops.
My phone has lived with i9100 battery for a couple of months.

You are right, the cheap battery are all fakes and don't work but anyway, the problem is that I'm from Argentina and because of new government rules related to importations, I cannot buy a i777 from outside and in my country is imposible to find them.
What do you mean by a normal one? I tried an original i9100 on my i777 and I got the loops .
The reason of this post is because long time ago I read, don't remember where, that with some roms the i9100 battery worked ok so I though that maybe something could be shut off o done in the roms/kernels to disable the NFC. I google a lot but I couldn't find anything and unfortunately I don't have much time to go around testing every single rom. :crying:
Sooo any help would be much appreciated.
Just in case, I'm using SHOstock3 rom, I cannot ask in his thread due to my "new" status but If anyone can ask him, maybe he can find a way to change something in the room to avoid the loops.
thanks!!!!

The cheap batteries are not all fake, I'm using one as well as others. It's true NFC capabilities are lost, but who cares: NFC barely worked for this device in the first place.

Define "fake".
For me, "fake" is when it says "SAMSUNG" on the battery, while it's not produced by Samsung, when it says "NFC" on the battery, but there's no NFC chip inside it, and when it states battery capacity, and the battery capacity isn't even 1/2 of the stated.
By all these criteria, the cheap batteries are fake. They don't have NFC chip, they're not produced by Samsung, they're not even the same batteries - you can read on Skyrocket forums, I've dismantled a true Samsung battery vs fake one and compared, it's easy to spot the fake by touch - the real battery fills all the possible space it has, the fake battery has a plastic holder around a smaller battery that's made to look and fit larger space. Of course, physically smaller battery also means - crappy capacity, nowhere near the "official" claim.
If you prefer other terms, like "counterfeit" - I don't mind the term as long as it stresses the right thing: these batteries aren't built by Samsung, aren't built by anyone that builds for Samsung, aren't of any "official" descent and are crappy (which makes their "SAMSUNG" sticker fake, by the way), so anyone who expects them to match the original battery is heading for a big disappointment. And I used 2 of those too, until I got annoyed enough that my wife's phone can't live till the end of the day, found and bought $30 original Samsung battery. Night and day difference. And the original battery is still alive till today.

I'm not sure of the reason for bootloops, but I'm quite sure it isn't NFC - because the fake cheap batteries don't have NFC either. The additional contact on the battery board is connected to nothing.
I always ran stock-derived ROMs on the phone (SHOStock mostly, but at some point - some other ROM I've ported from i9100), never had a problem running i9100 battery, both true and fake one.
If you can look at the logcat and pinpoint the failure that sends you into a bootloop - it might help.

No problem, how can I look at the logcat?

Here, a dismantled fake battery with marking, suggesting that it's the same fake model that is used for i9100. I've examined it under a microscope to make sure, and even on the photo one can almost see it - the leftmost contact has a board lead left with vias, the middle board contacts have vias, the rightmost contact - the one for "NFC" - has neither vias nor board lead, it's just there for show, connected nowhere.
For logcat, just search the web. You need to enable ADB and have drivers in the PC, apps are not good - because you need log from the boot time. One guide, for example:
http://forum.xda-developers.com/showthread.php?t=1726238
There are many more. Search "how to use adb logcat".

Good points, and good information; so by definition I should have said "counterfeit". Thanks for clarifying some things.

This is the one I'm using - 100% counterfeit but works fine. Does not support NFC but have never had any problems with it. It's cheap for a reason, as it's most definitely not 2200mAh (pretty much stock 1650mAh, or close to it), but it functions well enough for me.

@SteveMurphy
I just looked at the one you are using on ebay, it does not say anything about the battery cover for this 2200mAh. Does it same size as original that does not require new battery cover?
Thanks.

Differences between SGS II batteries...

I wanted to share my experience here in the general forum so others don't waste time, effort or money troubleshooting or buying an incompatible battery. Do to the I777 version of the SGS II using an NFC compliant battery, there is something unique within the battery and the way the phone is charged. In the past ALL SGS I batteries were interchangeable with the exception of the SCH-I500 Fascinate and it's variants having a different battery.
What does this mean?
It means that the SGS II I9100 Battery is NOT compatible with the SGS II I777. The NFC style battery is REQUIRED in the SGS II I777. If you use a base I9100 battery it will operate fine under any stand alone condition but whenever a USB cable is inserted, the phone will immediately go into chronic rebooting every 3 seconds and leave you wondering what is going on for the most part. The only mode this reboot doesn't affect is Download Mode.
What should I look for when buying a replacement?
Make sure the battery you buy is I777 compatible. Don't buy a plain SGS II I9100 battery and assume it will work. Until manufacturers begin to produce units that are compliant with both (backwards compatibility shouldn't be an issue). This should not apply to docks, chargers and cables and most likely is only battery specific.
I just wanted to share my experiences so you don't waste time and/or money buying an incompatible battery or troubleshooting an issue which can appear as software in the form of hard rebooting.
Below is a sample of the difference of the batteries in both model number, and front facing view of the NFC text found on the I777. The I9100 unit is on the right, and the I777 unit is on the left. Excuse the quality I found a random photo to use rather than take one...
Have more details on why the NFC unit is different? Post them up and I'll add them to the OP to help educate.
Did this post help you out? Click THANKS (below and to the right)...
Good find man.
Pics of the contacts, please
The contacts are the same. it is the internals of the batteries that are different.
Good post. Is it ok if I click the Thanks on the right instead of searching for the one on the left...?

Haha edited that one. +1 to the internals being the difference...
great find and great info! thanks for posting this.
i'm taking bets on how many threads will get created asking about why their phone is rebooting when they plug it in?
So if you buy an I900 compatible battery that charges via battery dock connector and never utilize a cord/usb to tether phone would you be OK?
Only reason I ask.....I have this on it's way from Amazon and have heard it works fine from my friend that utilizes the battery on his Samsung GS2.
http://www.amazon.com/Anker-x1900mA...=UTF8&coliid=IIQN5YJKPRZN8&colid=LM1H9GCPJU23
I am using a I9100 battery in my att gs2 with no problems
From my use they work just fine from a stand alone point. I do however have no long term results of what using a non NFC battery will do to it but to be honest during a dis-charge state, it shouldn't matter what battery is in there so long as the voltage is the same which in that case it is.
Stupid question: What about in reverse?
I have a non-NFC UK SGS II...could I use an I777 battery safely inside it?
Additionally, would it be possible with the rightsoftware to utilize that NFC?
(basically got lied to on ebay, been perpetually bummed about lack of NFC)

No, the battery only has the antenna I'm fairly certain. The NFC controller itself is in the phone I'm fairly certain.

I'm using an i777 battery in my i9100 while typing this... needless to say it works fine. The only physical difference I can tell is the i777 battery is a hair thicker if you lay them side by side on a flat surface and get level with yotur eyes... the voltage and everything else is identical... definitely not sweating it. IV been using it for 3 days now. As for long term, still should be fine. But its on you if not... I'm no battery "expert" but I do understand basic AC/DC.

Korean 2000 MAh Battery NFC wont work (?) Anyone have one?

I just got this battery from ebay:
http://www.ebay.com/itm/260899780576?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
NFC doesn't work. I found a picture of the Korean S2 and it seems the better contacts on the Korean model is on the opposite side as the i777. So it seem the NFC side of the battery is facing inward instead of outward when used with the i777 and I'm guessing that is why it doesn't work.
Anyone with a Korean 2000mah battery that can confirm that NFC does not work?
Very disappointing as the battery was not cheap.
I can't be the only one that bought the Korean battery for NFC and extended life.
Just need need to know if I'm correct and NFC doesn't work.
Anyone?
If you can I would try and get your money back. It sounds like it could be a knock off, as the only extended NFC battery that actually worked had the contacts as normal. Also what have you tried to do, read a tag, beam?
Sent from my SGH-I777 using Tapatalk 2
Thanks for the reply...
I have tried both reading tags ans beaming to my other phone. It all works with. My original battery but not the new one.
Seeing pictures of the Korean S II I noticed the contacts are on the other side thus the batter would have to be flipped to be inserted. This is why I think the NFC side faces the wrong way when incerted in the i777. Both batteries have the small rise on one side where the NFC circuits (not sure what to call them), but when you insert the new "Korean" battery that side faces in instead of out as the battery has to be flipped.
Do you have a Korean battery?

I've gone back to the stock battery for the NFC functionality. I guess I'm going to look for and buy another stock battery, if I want NFC.
I asked the seller about it and he said:
Hello. Sorry for the inconvenience.
No problem, This is a Original extended back cover and 2000mAh battery.
The EB-K1A2EBSG is the Korean version of the Export Privé, and was supposed to be compatible with all Galaxy S 2 versions.
However, in each country, depending on the carrier that does not support NFC.
Samsung Electronics has confirmed this part.
Please contact the carrier on your smartphone.
For example, AT & T, AT & T, T-Mobile, Sprint and so.
Once again, Sorry for the inconvenience.
Thanks.
When I replied that my stock battery worked fine with NFC and I don't understand how contacting my carrier (AT&T) would help. THen he replied:
Hello. Thank you for response.
Because each country, depending on the version of the NFC-compatible problem occurs.
We do not sell International Version and can not solve this part.
We did guide in the product description. Please refer.
Thanks.
So he's pretty useless.
I have read that others have bought the Korean battery, but never mention NFC functionality. So as far as I can tell if you want NFC stick to the stock battery.

the nfc wire of the Korean battery is said to be on the other side, opposite to that of the att version. Thus nfc cannot work with a korean battery inside.

Yes, seems so. Unfortunately, it was posted many times that you needed the Korean batttery if you wanted NFC. There where even several people that had ordered the Korean battery and talk of having to modify the back cover, but no one cought on to the NFC being on the other side of the batttery. At least I saw no mention until I posted it.
I'm back to using the standard battery.

I have just caught on to this thread because I just picked up some NFC tags to play around with (until now, have had no other devices/cards with NFC). I also have the Korean NFC battery, and it's not working. I'll test the stock 1650mah battery in a few days when I return home from a trip. It sucks that NFC won't work--this phone with the 2000mah battery is pretty great.
EDIT: stock 1650mah battery works with my tags. So Korean extended battery definitely does NOT do NFC.
Can you remove the front thin layer of the battery and flip the nfc wire to the back? Since its inverted can the nfc work through the front of the phone?

[Q] TS came dead, any way to make it work?

Hello guys,
my dad backed TS on kickstarter (probably) and then since it took so long for him to get his watch he bought galaxy gear instead so when it finally arrived it was just siting there unopened until few months later (now) when I found out and wanted to give it a spin. It didn't turn on.
It is 1GB ram model probably for Europe since 3g frequency is stated to be 2100MHz on the box
there is no response to either charging or pushing the power button, it is registered but not recognized when plug into a PC(no change on the watch itself)
I have tried nothing and I'm out of ideas I only tried to take the battery out for a bit and then putting it back in with no result
Any suggestions on how to make it work? Battery is dead? I read on the forum that the product is not very good but I would still love to give it a try.
replacement battery
ok so since nobody has a better idea I'm thinking that it is just that the battery is completely depleated. Is there a way to charge it outside of the watch? Or where can I buy new one?
Thanks, Andress

---------- Post added at 09:50 PM ---------- Previous post was at 09:45 PM ----------
oh I realised that TS was shipped with a spare battery. You should have a second spare battery. If so, then you could try replacing a battery. Normally batteries are stored with 50% charge, because that's best for battery life. So it should have some charge, at least enough to start charging.
it didnt have the spare battery when it came
also in the mean time I checked with voltmeter and the battery is dead so do you know where to buy new one?
Try universal charger
It's quite a common problem with phone batteries not in use for a long time. I used universal charger "Ansmann Vario pro" to get them alive - few times with success. Not necessary this model - look for anyone with adjustable pins.

Battery Replacement - is it possible? Where to buy?

Hi guys,
my Nexus 9 started to randomly shutdown around 40-50% with some strange noises and screen artefacts. I know some people faced that as well. I've tried to go trough that google support bull*hit and finally when we agreed it's battery issue, they stopped answering - seriously.
So I've removed the back cover - it's pretty easy. The battery is 2 pieces, one is ok, the second is probably dead - very bloated. So I need a new battery and it will probably be ok. BUT the battery is impossible to buy
I've contacted our local HTC partner repair centre, but they told me, they no longer do repairs, they just send it to HTC, so they cannot say how much will the battery replacement cost :silly:
So finally the question - is there any way how to get a new battery for the Nexus 9? Swap is super easy and paying half a price of the tablet for battery replacement, which I can do in 3 minutes is just lame.
Anyone saw Nexus 9 battery as spare part? Anywhere? I've found a guy in Poland, but he's not replying to my emails.
Thanks!

Don't waste your time putting a new battery in it. It's a hardware issue. My first N9 thr exact same issue after 4 months of use and ultimately had to be replaced. There's another forum here on XDA pertaining to the exact same issue. Under 50% screen locks up with a scrambled image and loud noise from the speakers. It's a bad motherboard and the only fix is a new motherboard or new Nexus 9. Trust me on this. You can replace the battery, but it won't help this issue. Sorry

Furthermore, both Google and HTC know of this issue. I swear they instruct their tech people to play dumb.
Sadly that make sense. After I've send a few photos, when I was quick enough to take a photo of the display before shutdown, google support went silent!
These are not a good news, but I thank you for reply and sharing some light on it. I will consider buying a new tablet then.

Makes sense. My N9 has had minimal use (displaced by Pixel-C). Brought it out of hibernation a while back, and it kees crashing (even when on charge!)
I've had this problem with crashing and loud noises several times. Previously I had a charging issue, under warranty the mainboard was replaced. A long while after that the problems with scrambled screen and loud noises started. I then disconnected the battery, and reconnected it, and the problem went away for a long time. But it has returned and even returning more often.
So I ordered a replacement battery via ebay (straight from China), and yesterday I finally found some time to replace it. First thing I noticed the tablet is more responsive, snappier.. It hasn't discharged enough to reproduce the problem, but I had trouble lately with updating apps when it wasn't on the powersupply, which convinced me it was a faulty battery. Now it's updating without charger no problem at all.
2,5 weeks after replacing the battery, and the problem did not come back. I'm happy with it.. pretty easy fix..
So the same problem has been happening to me also, got the N9 up to 7.1.1 and this started to happen a lot more. Seems to be when the battery is low (under 50% or 40%, somewhere around there) and usually when I'm looking at the Chive app, mostly again with animated GIF's they have. I'm not sure it's happened with games since I mostly game on my N6 since it has more RAM so it plays a bit better where the 2GB on the N9 is too laggy.
Any way, so this happens now too. So some say bad motherboard, others say bad battery. Has anyone gone through the trouble of the motherboard replacement? Or have actually had HTC replace the motherboard on warranty? If yes, has it made the problem go away? Has anyone else bought a battery off eBay (I can't find them new OEM anywhere and I hate the idea of a Chinese knockoff so close to my hands and face - ya know, fire) and had the problem go away?
I've replace all manners of parts from various phones so I know I can do it to the N9, which is just a large ass phone. I have to give up my N9 for some Samsung tablet (sorry 7" tablets are too small). I love having a 8"-10", pure vanilla Android tablet. I wish Google would make another one that was like the N9.

So the same problem has been happening to me also, got the N9 up to 7.1.1 and this started to happen a lot more. Seems to be when the battery is low (under 50% or 40%, somewhere around there) and usually when I'm looking at the Chive app, mostly again with animated GIF's they have. I'm not sure it's happened with games since I mostly game on my N6 since it has more RAM so it plays a bit better where the 2GB on the N9 is too laggy.
Any way, so this happens now too. So some say bad motherboard, others say bad battery. Has anyone gone through the trouble of the motherboard replacement? Or have actually had HTC replace the motherboard on warranty? If yes, has it made the problem go away? Has anyone else bought a battery off eBay (I can't find them new OEM anywhere and I hate the idea of a Chinese knockoff so close to my hands and face - ya know, fire) and had the problem go away?
I've replace all manners of parts from various phones so I know I can do it to the N9, which is just a large ass phone.

I couldn't figure out how to unplug the cables.
You need to pull it vertically from the board. I used a guitar pick to make it a bit looser, then I pulled it of.

Is it still working?
I am pretty sure is the battery connector. I unplugged and replugged the connector and the problem was gone for a few days. I could finally solve it applying a contact cleansing spray to the connector and then using a special kind of glue which is typically used to prevent screws for unfasten. It has worked perfectly since then, no need to replace the battery.

Just wanted to be sure this was the root cause.
Already exchanged my battery in the meantime.
Thanks anyway!
I installed a replacement battery six months ago due to shortening run times on the original battery. I purchased it from newpower99.com for $60. They have an instructional video on their site that shows how to replace the Nexus 9's battery. It worked well for me, giving me a run time that was comparable to the run time when the Nexus 9 was new.

Battery Replacement on HP Touchpad

HI All,
I wasn't even sure I was going to post this or not but I thought it might help someone out. This is not meant to be a "how to" post and you should proceed at your own risk.
A friend of mine had a 16gb Touchpad that he hadn't used in several years. It was just sitting in a box for several years. When I told him I was still using mine to watch videos and such he decided to dig his out. Unfortunately it wasn't in very good shape. The battery had swollen and had practically pop the screen out of the case. I'm fairly handy at fixing things so I told him I would give it a shot to replace the battery.
I wasn't very hard to open the case because the swollen battery had pushed the screen up and gave me easy access to the clips that hold the screen in. By gently prying up under the screen to released the remaining clips the screen came away from the other half. There are 2 cables attaching the screen to the MB so be careful. I wish I would have taken more pics but I didn't think about posting a how to. There are a couple of good how to's online and batteries are available online for around $30.

Once I separated the screen from the body I had to pry the battery out. It is stuck down with some pretty sticky tape on the underside of the battery. You have to pry up pretty hard but you also have to be gentle as not to damage the copper foil that is under the battery. Once the battery is free you can give it a little pull to disconnect the cable from the motherboard. The online how to has you disconnecting all the little cables from the MB and actually removing the whole MB from the case. This is not necessary. The only thing that needs to be removed is the usb module and one or two screws from the MB near the battery connector. With a little patients, good light you should be able to mate the new battery plug to the connector. Just make sure you line the two connectors up and use a small tool to push the plug all the way onto the connector. Now once the battery is installed just replaced the parts in reverse order and you should be good to go.
Hope this helps someone,
Cheers
Thanks! My battery is equally swollen but working just fine, so I'm not sure if I need to do this before it fails. I hope it doesn't explode further or cause a fire!
It's curious, I was going to open a new thread right about that and I've found yours!
I extracted the old swallen battery from my touchpad many months ago but I still have to buy a new battery.
I believe that the batteries sold online were producted many years ago and, considering the value of the touchpad on the used market, 30 dollars are not little in my opinion.
Does anybody by chance know of any cheaper alternative battery that could be adapted to the touchpad?

They are lithium. If the pack is swollen it has gone bad.
Replace as soon as possible. The risks with lithium are too high.
Hi all,
It's over 4 years since the last posting in this thread, but thought I'd check in anyway.
The battery in my Touchpad does not appear to be swollen (no obvious bulging in the case. However, it seems the battery is not retaining a charge as long as it used to so I'm wondering if anyone has a legit source for a replacement. My backup plan is to take the TP apart and see if I can provide an access point for an external source (battery or P/S) and would be interested f anyone has done this, as well.
The TP is certainly not as fast or have as much memory capacity as current tablets, but its display is beautiful and the price was certainly right (firesale
Thanks in advance for any help.....cheers (and happy upcoming holidays!

You can look for all about the battery on this thread:
https://forum.xda-developers.com/t/hp-touchpad-poweroff-prevents-battery-drain.4002265/
If the Tablet boots, then just keep it charging.
This thread provides some information on how to wake up the battery:

Appreciate the links. They were helpful. However, it did not answer my specific question: Replacement battery and a reliable source for it. I will try some of the suggestions to see if I can "rebuild" the battery charging capacity, but at 11 years old, there will be limits to doing this.
Cheers and happy holidays back to you....
