[Galaxy S II Q&A, Help & Troubleshooting] marcfields:
Hi all,

I've got my sg2 since june and since the first moment I have got the same problems. I had the stock ROM & kernel with android 2.3.3. The problems I experienced were these:

1) extreme low battery life (6-10 hours, with normal usage)

2) when using heavy apps, my s2 just suddenly turns of. When rebooting it, it has a battery drop of like ~15%. (this only occurs when battery is already bellow 40% left).

3) Like 5-20 times a day (it really difference day-to-day), I got the notification that I have to put my sg2 on a charger. - So the battery bar drops from example 80% to 1%. After like 1 or 2 minutes it just fills up back again to the 80% before. Sometimes when this occurs, it also turns in a few % (like 80% before, and afterwards 75%).

So what did I already tried to fix this?:

- bought new 1600mah battery > didnt solve the problem, conclusion: no hardware malfunction

- I thought the problems could be occured by the tiny space between the battery and the frame of the phone. So it had a lack in connection... So I filled up the little space with i tiny piece of paper> nope didnt helped.

- downloaded mutiply apps for battery saving, task killers, etc etc.> didnt help!

It's really really frustrating, and I'm guessing more and more it's just a software problem. I do have warranty/insurance on it, but i don't want to send my phone to a repairservice because then I've no phone for like 3 or 4 weeks.

So my last option for me was to try a custom ROM and Kernel. So last week I installed the Lite'ning ROM. I also followed up the advice to calibrate my battery, so i did.

And the first day it was running really smoothed! At the end of the day my battery was still alive and I've used it for over 20hours, so I was really statisfied... But a small sidenote: I had a really busy day at work, so I didnt use my phone that much.

So next day, used it alot more. After 5 hours it had only 50% left.... And that's not all, my phone turned off suddenly. Not once, not twice, but 5 times that day.

Seems all these solutions didnt help. The only positive thing of installing Lite'ning ROM is that i now have about 4 or 5 hours more battery life a day.. But if I use it alot, it shut downs a lot more. Wich lead in more battery drops after reboot.

I'm really desperate, and I really don't know what to do now. Does someone have got these really frustrating problems, and do you guys have got some solutions?

And one more question: is my warranty/issurance voided after installing the Lite'ning 6.1 ROM? or can it by tresspassed by using a Jig?

Tnx for your time, and I really really hope you guys can help me cause i'm really getting sick of all this. It's killing me!!!

ps. sorry for my bad english
[Galaxy S II Q&A, Help & Troubleshooting] vickarul:
your warranty is voided by installing custom rom but u can unroot and use the jig to remove counts in counter.

now apart from that it seems if u use your phone for 5-6 hours continuous it will drain the battery because main source of battery drain is the screen display but for moderate use it should be a little over a day.

i am unclear about your usage but still if you have doubts you should really get it checked at a service center. :(
[Galaxy S II Q&A, Help & Troubleshooting] BrandoHD:
I would flash back to stock, use the jig to clear the flash counter and exchange that phone, seems it has some type of hardware issue that could be related to temperature as it only shuts down when you use it.

My 0.02 cents
[Galaxy S II Q&A, Help & Troubleshooting] marcfields:
My usage is definetly not THAT extreme, i guess moderate: I never watch movies or youtube, just some messages with WhatsApp, about 4 of 5 times a day checking Facebook, same for Twitter, always GPS off, some time of the day Wi-fi on, never play games, always closing apps on background.

i've got an example of my battery usage (this is one of the best battery usage days i got!!!):

I am running Taboonay 2.0 and wanted to apply one of the custom kernels. I see people mostly use either thor (tegraowners) and richardtrip kernels. Can somebody enlighten me on the pros, cons and main difference between the two (especially if you had experience with both). I tried to search but could find any thread detailing this information. Thanks in advance.
[Acer Iconia A500] FloatingFatMan:
RichardTrip Kernel. Complies fully with GPL requirements, Source code is available.

Thor Kernel. Does NOT comply with GPL requirements. Source code NOT available.

Otherwise, doesn't really matter. GPL compliance is the main pro/con.
[Acer Iconia A500] DRTMI:
Try both and see what your tab likes better. I tried both and am now on Thor 3.4 and am able to o/c to 1.68 stable.
[Acer Iconia A500] mburke178:
i don't see how GPL compliance is a pro or con to much of anybody except developers. The majority of people wouldn't know what to do with the source code if it was released.

I would however agree with the previous post. Try both out and see which runs better on your tablet. They are both well built kernels. Also read through each of the kernels forum post and see what issues people are having with each kernel. If the issues being had don't effect you and your tablet runs good on said kernel i would say you have your winner.
[Acer Iconia A500] Biologos:
I really don't understand why the discussion had to go to GPL, once again. Arguing over GPL compliance in such a topic is just about semantics. The majority of the end users don't really care, one way or the other. The OP was asking to see which of the two gives him better value for his device, with the fewer problems. Saying that the main pro/con is the compliance or lack thereof to the GPL is totally not helpful.
[Acer Iconia A500] lk757:
This is absolutely correct. I am basically trying to understand the difference between two kernels from the technical standpoint as it relates to functionality/performance/stability/design. Having said that, still knowing that one kernel is GPL as opposed to the other is an interesting fact to know and at least provides some information (though you are correct to point out that this likely does not make much difference to me or others when choosing one over the other).

Also, replies of sort "try both and see for yourself..." are absolutely inane. Obviously, I can and most likely will try both of them. That is not the point of my original post. I was just hoping for some technical and user experience insight from people who used it and/or worked on it. Thanks.
[Acer Iconia A500] mburke178:
there really is no good answer for you. Look at each thread, they both have similar if not the same modules built in, they both have OC ability, they both have great dev support.

The only issues i see or hear from thor's kernel is stability to SOME people. Some CPUs don't seem to be able to OC the same as others, not a fault of the dev but a hardware issue. I have personally been running this kernel for 3 days with no issues OC @ 1680 and no undervolting.

Don't really know much on Richard Trip's kernel, but like i said read through his thread and see if anybody is experiencing issues related to his kernel.

Everybody uses their tablet for different things and the kernel/OC they have may act differently when you use it. There is no real good answer for the vague question you asked. Until you ask specific questions, not just thor vs richard trip, you won't get the answer you are looking for.
[Xperia Arc Accessories] umz_786:
I know not to buy any old battery from ebay because it will most probably be poor quality, unsafe and old (An engadget article showed lots of batteries being relabelled as new)

But I saw a 2430mah battery for the arc on ebay and the only reason why I am considering it is because the seller, e-cell, are very good, reliable and honest. I have bought a lot from them (not batteries though) so Im seriously considering whether to go for these. Some plus points:

Made in japan, not china

Offers 1000mah more but same size as original

Seller has already sold 25 and has 98.6% feedback from 75,000 sales

2 year warranty included

At £13 price is a bit suspect so should I go for it?
[Xperia Arc Accessories] martin132014:
Well, i also have bought 1800mAh battery from ebay and it cost RM8.00 only and thats very cheap even for a 2nd hand batteries. I used it for a couple of days and the performance is the same as original 1500mAh battery from Sony...but the difference is that the temp. of the battery. Well i don't know if it is the battery or not but the temperature of the ebay battery is kinday low..I have used the original, when i surf the internet the temp will go up to 41`c but the ebay one only up to 28`c even for long hour of uses, and my phone not responded like i wanted.....well i don't know if it is the battery or not..

But if it's me, i buy the battery cause it's cheap anyway right...what you gonna lose..Just buy and if it's good then great, if it's bad, just feedback to the seller about it...

well thats me anyway...:D
[Xperia Arc Accessories] superlimau:
So did you buy and try out the battery?
[Xperia Arc Accessories] umz_786:
It's on its way
[Xperia Arc Accessories] superlimau:
Keep us posted, I bought the Andida from obostore.com and its worth for its price as it almost similar to the original one
[Xperia Arc Accessories] pinoypower:
Is this the one labeled "GOLD"? I would be very careful. Yes, e-cell is a good seller, I've bought other stuffs from them too. I bought a "GOLD 1930 mAH, Made in Japan" battery from them for my old Samsung Galaxy S last year, but the battery lasted way less than the stock battery, and did not improve even after over 10 charging cycles. I've emailed them about my observation, their customer service came back to me rather quick and advised me to return the battery, to which I did not as it was just a bit of a hassle for me.

Hi im goin to get a sub AU$200 android phone for my bday. The two im deciding between are the lg optimus one (AU$199) or the huawei sonic (AU$188).

thanks in advance to anyone that helps :)
[Optimus One, P500, V General] NeverFlash:
lg P500 thread will only support P500 :)
[Optimus One, P500, V General] deetailed:
For me the cincher would be RAM. O1 has 512mb while Sonic just has 256, even though Sonic is newer. Plus if you like tinkering with custom ROMs and kernels, community support for O1 is better than any sub-$200 Android phone that I know.

That said, if you can get an O1 successor like Optimus Net or Optimus Hub, those are like O1 with better camera but same price, so I would put them in consideration too.
[Optimus One, P500, V General] M95M:
I consider this same phone. I think that optimus is better, cause has more RAM.

But sonic isn't bad. I don't know, I ask each friends but I still don't know. Can you help me?

First off thanks for all the the great roms and how to's to all the devs ... I have flashed to stock 3.2 now i can't gain root ..... any ideas???
[Acer Iconia A500] FloatingFatMan:
Currently there is no way to root the stock 3.2 FOTA. Nor can you go back to the older ROMs as a new bootloader was written when you flashed.

itsmagic and CWM no longer work.
[Acer Iconia A500] plemme61:
Thanks for the the quick reply... was afraid of that answer ,guess I am gonna have to wait. I sure someone will figure it out real soon ...
[Acer Iconia A500] FloatingFatMan:
Always a good idea to search XDA before flashing a new ROM for your device. :p
[Acer Iconia A500] TiboTheGentleman:
or like me, I was in 3.1 stock, waiting for the 3.2 update and custom ROM.

But my girlfriend find the time to update it without me :eek:

Now i've to wait for the root of 3.2 from scratch :D

Niarf
[Acer Iconia A500] erica_renee:
I Sees how you are blame the woman.

Booohoooo.
[Acer Iconia A500] camino62:
I'm having the same problem. Just after buying my A500, I updated it to 3.2 but I didn't know that root wasn't available in that version. Nor that I couldn't downgrade to 3.1 because of the new bootloader.

Does anyone know if it's possible to downgrade this bootloader in order to downgrade to stock 3.1 rom too? I feel that the answer is that it's not possible...
[Acer Iconia A500] pacificwing:
No. It's not currently possible.

I'll probably get people barking at me for suggesting this, but given that you've only recently purchased your tablet, you could always take it back and exchange it. Depending on where you got it from, they may have a satisfaction return window (usually 14-30 days for big box retail). This would allow you to return to an older version, or upgrade to a custom 3.2 ROM instead.

Normally this type of behavior is frowned upon, mainly because it is speculated to result in raised prices of consumer products in general. In truth, really it is up to the retailer. If they are willing to observe a satisfaction return policy, and you are unsatisfied with the product, you are operating within the business perimeters that they've established. It wouldn't be illegal, so its merely a question of your own morality and your willingness to take advantage.

I guess it depends on how badly you need root. For me, it is a show-stopper. My tablet sits at home now that I've lost root, mainly because it is useless for my needs without ad-hoc support.

Or you could just wait for the 3.2 root, but my gut tells me it might be a while. I don't know why, but I have a bad feeling about this particular upgrade. That's not really based on anything factual though.

Cheers,

[Acer Iconia A500] kjy2010:
That could be because most of the "real A500 DEVS" ( not just ROM chefs) have left this forum for a less hostile environment.

I was going to wait for the 3.2 root but now that you say it might take (lot of) time, I think I'll try to give it back to the store.

I need this root for many things, ie : mounting my nas shared folders.
[Acer Iconia A500] ve6rah:
I use ES file explorer, and it opens my NAS shared folders just fine without root.

(of course I also want root for many things, that's just not one of them anymore)
[Acer Iconia A500] iepanx:
can't wait untill the root for 3.2 it's coming! please crack that off!
[Acer Iconia A500] Luescoff:
I'm waiting for 3.2 root.

I'm also waiting for 3.2 root, because i want stock 3.2 with root. Right now i'm on Honeyvillain 1.2 with no issues so far, only SU. But that's a common problem right now for 3.2 ROMS.
[Acer Iconia A500] Mircoron:
What do you think about change wpa_supplicant in update.zip before flash with a version that support ad-hoc network? :confused:
[Acer Iconia A500] ve6rah:
Once you are on stock 3.2 you can not root, and you can not downgrade, and you can not flash any modified or non-stock image. There is simply no way to do this until someone finds a way to root 3.2
[Acer Iconia A500] Mircoron:
Too like i-pad :(:(:(
[Acer Iconia A500] Omaticayan:
I guess that's not correct, at least for A501 but I think for A500, too.

I followed those steps to get a rooted HC 3.2 for my A501:

- Download HC 3.1: Acer_A500_4.017.07_EMEA_CUS7 http://cdn.acer.futuredial.com/Acer_A500_0.000.00_4.017.07_EMEA_CUS7_1311771237783_253e5e46.zip

- Download Decrypter [DEV][APP] http://xdaforums.com/showthread.php?t=1099673

- Decrypt downloaded file with Decrypter (put Decrypter and Acer_A500_0.000.00_4.017.03_EMEA_CUS7.zip into same folder)

- Unzip Acer_A500_0.000.00_4.017.03_EMEA_CUS7_decrypt.zip

- Copy update.zip from the above package to MicroSD card of A501

- shutdown (NOT restart!) A501

- Power up the tablet using Volume - & Power buttons (hold buttons until text shows up)

- A501 finds update.zip and Update will commence

After that you will have HC 3.1 on your tablet. Now root your tablet with iconiaroot 1.3 (use google to find the apk). Once it is rooted you are able to install ClockWorkMod via Acer Recovery Installer from Market, there's a thread somewhere around here, too.

Then look at thread:

[ROM][24.08]Acer A500 HC 3.2 4.015.01[HC 3.2][CWM & root] - xda-developers

So far I have no problems, everything's seem to work okay, WiFi, Bluetooth, 3G...

Hope this helps! However, I am not responsible if you brick your device! Do it on your own risk!

[Acer Iconia A500] hapid:
I followed this guied already mentioned in other forums. I reach the point heaving 3.1 on the tablet - I guess - but mine at least is not starting whit this room. "Boot validated failed..." There is also a room which is supposed to downgrade to 3.0.1 for A501 but same outcome. My table was factorishipped with 3.2 (or somebody updated it - hate him). If somebody else tries this, please report on the outcome. If you brick your tablet whit error message "Boot validated failed..." you can reanimate it with the A501 3.2 room found in this forum.

I absolutely agree, if it goes ahead like this, I will reach the point to change to I-Pad. For a closed system I consider it as the better choise. :mad:
[Acer Iconia A500] Mircoron:
I will try it, from wich version you started? I tried some rom after installed 3.2 but the message at start is alway the same "boot validated failed" :(
[Acer Iconia A500] :
My A501 was on HC 3.0.1 ex works, rooted it with iconiaroot...

then upgraded to stock 3.2 OTA, lost root of course...

then rooted again with the aforementioned method...

...and happy since then... :D

[Acer Iconia A500] synapses11:
You say you updated to OTA 3.2 but did you download that from here or did you do the update directly from the update on your tab?

If you're an A500 owner with the true 3.2 stock updated via your tab, don't waste your time doing this. Won't do any good.
[Acer Iconia A500] ve6rah:
Tme and time again people post this "solution" failing to read or realize that you can not flash a 3.1 rom over the stock 3.2

This doesnt work. People who did the official OTA 3.2 update can not downgrade!
[Acer Iconia A500] brnakp:
I have rooted A501 with HC3.2

I used the same procedure as was described by Omaticayan (werner). I also have german A501 originally with HC 3.0.1 updated via OTA to HC 3.2.

The only difference is that I used this version of HC to downgrade: Acer_A501_1.309.02_COM_GEN1_SD_update.zip

It was HC3.0.1 for A501, then it was possible to root it with Iconiaroot 1.3 app, install AcerRecovery etc.

Hi Its been more than 2 weeks from when the stock 3.2 was released. is the 3.2 ROM so hard to root for the devs. or is it that the devs are busY?
[Acer Iconia A500] ve6rah:
well I got the revert to work, so the "official" root method for 3.2 at the moment appears to be revert to 3.0.1, upgrade to 3.1, root, install clockwork recovery, install custom rooted 3.2 rom

It's progress, things don't happen instantly, but it's a step forward. As I mentioned in another thread, hopefully devs will be able to take this information and modify it to make it easier and quicker, but for the moment there's at least a method.
[Acer Iconia A500] :

[Sony Ericsson XPERIA X10 Mini] mattes13:
[Q1] I was using paul-xxx's custom RIM MiniCM Pro. Last saturday, it refused to boot and got stuck while showing white "Sony Ericssson" on black screen.

So I reflashed the stock ROM and it worked again. Rooted and flashed with custom -> stopped working.

[A1] The answer was my SD-card. After I took it out, phone booted normally. So I formatted it and put it back - still working.

The difference to the stock ROM is that most custom ROMs use higher Android versions which include using a part of the SD-card for apps. So I guess, something happens here and sometimes. A friend of mine had a similar problem with his HTC desire.

[Q2]: Does anybody know, what exactly could have happend?
