For me its WORKS my phone is alive again... But i have one question about all of this "problem" U write

[Q] What kind of failure is this 0% battery issue?

[A] This is an unrecoverable hardware failure on the fuel gauge controller of the Arc/Neo. On our research, we concluded that no software can correct this.

How it happen im just downgrade soft and try to root so how i can damage HW (overheat for example)? I think its some SW problem, some area's what dont update or somthink i dont know its my frst android phone (mt15i)
[Xperia Arc General] prance666:
i have this lines in my log:

<6>bq27520 0-0055: FW v5.7 (expect v5.7). Golden FW v1.12
<3>power_supply bq27520: driver failed to report `voltage_now' property

is this mean i have 0% problem ?
[Xperia Arc General] Bazoocaze:
The FuelGaugeFix doesnt need root, as long as you use the latest kernel patch.

By the way, the error message you show indicates that you don't have the kernel patch. The FuelGaugeFix app needs the kernel patch to work. Please flash the kernel patch, or use a ROM allready patched (like DooMKernel).
[Xperia Arc General] Bazoocaze:
Yes.

The downgrade process rendered the fuel gauge in an invalid and unrecoverable state, so you bricked your fuel gauge. Invalid because it is not responding for i2c commands, and unrecoverable because it needs to respond i2c commands to upload the correct firmware.

When you "brick" a device it indicates that the software render the hardware unusable, so it`s an absolutely possible condition, and this is what happened to the fuel gauge chip.

From the point of view from the phone motherboard, the fuel gauge is a hardware, so it`s an unrecoverable hardware failure (needs replacement of the chip). From the point of view from the Fuel Gauge chip (bq27520), it`s a software failure (uploaded incorrect firmware), so it`s an unrecoverable software failure (needs reflashing of correct firmware).

No, it`s normal.

The first line (Golden FW v1.12) indicates you DON`T HAVE the fuel gauge issue.

The second line (failed to report...) is absolutely normal, and is show on nearly all ARC/Neo (mine, that doesnt have the issue, shows that line).

Can any1 send me folder from neo soft with WORKING baterry (without 0% issue)..... folder is in ROOT/sys/class/power_suply i see that in my folder are more folders and files in this folders have 0 bytes i try to replace it and chceck maybe it will work.

Or can any1 tell me how to extract FTF and IMG files (soft file) in windows7 i think the files what im looking are there too
[Xperia Arc General] Bazoocaze:
The files in /sys folder are not real files, but are created on the fly by the running kernel and drivers - you can't copy your files to there. You don't have the .../power/bq27520 folder because the fuel gauge driver that creates the bq27520 folder is not loaded on your phone. The only reason I know to the bq27520 fuel gauge driver fail to load on an Xperia phone is a dead fuel gauge, so in this case you must use a patched kernel, with the driver I modified to load correctly in presence of the faulty fuel gauge.

Forget putting files in the /sys folder, and flash your phone with the patched kernel/ROM.
[Xperia Arc General] Kuter_tm:
*The only reason I know to the bq27520 fuel gauge driver fail to load on an Xperia phone is a dead fuel gauge,*

So we need to find another solution cos i dont belive that is dead becouse downgrade..... it can be dead HW if i mechanical (by tools or somethink) crush it, hit it or somthink. I belive that is becouse somthink is not update to phone or updater cant overwrite a file (blocked by Gingerbread). Fuel guage not crash after downgrade its crash after i try ROOT phone by Gingerbread and after that fuel guage is dead. I dont know about linux and programing but im think we should start with checking Gingerbread and see what exacly it do, what block what change and maybe we find solution. BTW there is any way to clear all from phone memory i mean to delete all andriod files (like its new from factory), then install it on clean phone....

FuelGaugeFix app BETA v1.6

This is the FuelGaugeFix app BETA v1.6, with support for ondemand CPU clock detection and current consumption calculation.

This is a BETA version, so please test it and report back your impressions:

So, this is what you will get with this version:

- Battery consumption when listening music/video: if you listen 1 hour of music, the real Arc battery will drain 1 hour on CPU on minimal clock plus a little current from speakers. The calculated value now know that your CPU is working on the 1 hour period, and guess the consumption based on the CPU clock on the period. The current from speakers still be ignored (can't be guess for sure).

- Battery consumption when gaming: before this update, the app only calculate the consumption of the peripheral, so when gaming you only have the consumption from the display and a few other hardware (like the active cel radio). Now the app will read the CPU clock and estimate (best guess) the current consumption based on the clock and workload of the running game.

The formula used for clock consumption was:

current = clock * current_per_mhz + fixed_consumption

where:

current(ua): instant current

clock: cpu clock in MHz

current_per_mhz: 100uA/MHz

fixed_consumption: 25000uA

PS: all the values are based on tests made on my Arc. The current is the instant current, that will be divided by the time of measurement. The current in deepsleep will be maintained in 1mA.

So, if you use a lot of gaming or video/music listening, please test this version and report back.
[Xperia Arc General] Bazoocaze:
Good lucky finding another solution. And please report here if you find some news about the issue. Thank you.
[Xperia Arc General] ST4YSTR0NG:
So any ideas why they would make changes to the firmware? Maybe for better reading or something? But even that seems unnecessary. Im also guessing that ur unable to see what changes they made, if they did make changes because that would have been easy.
[Xperia Arc General] Kuter_tm:
Like i say i dont know nothing about linux i have just one time instaled it on PC. BNut i know that it have open kernel so its chanbe fix. This nice lady say that Bq27520 can be flash

http://www.youtube.com/watch?v=lLSJv22Nw3U&feature=colike

So maybe after root with Gingerbread some wrong code was write to fuel gauge?

I just try to help nothink more
[Xperia Arc General] Kuter_tm:
Bazoocaze one more question.... i want to give phone to GSM service just for soft change (by specjal program as they say with box or somethink) and my question is my phone is not under warranty so they want money, (question) there is any chance that they can fix it by using this magic specjal program to soft update
[Xperia Arc General] Bazoocaze:
In respect to the fuel gauge, I think it can't be fixed by any software, because the chip is in an unrecoverable invalid state, resulting in failure to communicate in the i2c bus (the chip is deaf to communications).

There is no chance they can fix it by software update.

Anyone experiencing random reboots ?

Since i fixed the battery problem using FuelGaugeFix i'm experiencing random reboots of my device.

I always keep it plugged during almost the whole day, and i can see the device reboots with no reason.

I don't know if this is related though... So i'm asking if anyone is experiencing the same ?
[Xperia Arc General] boss134:
Crazy Idea

Hi maybe if this Fuel gauge chip is somewhere on motherboard we can dissemble our phones and reprogram it.
[Xperia Arc General] zdzihu:
It is possible (and not too difficult) to reflash bq275xx soc. In fact, if you have an access to EV2300 board (which is quite popular eval board used to refurbish laptop batteries), the process is very simple. The only obstacle here for me is to solder/desolder this small SMD piece :)

You could also investigate the mainboard for a track/pin to access HDQ (single wire serial interface) of fuelgauge and try to program it that way (the process is documented in various pdfs on TI site).

Cheers,

My phones does reboot every now and then. Like if I go to sleep while charging it, it reboots at some point.
[Xperia Arc General] Bazoocaze:
Ok, I will do some tests on my phone, but until now It apears to be normal here (5% per night).
[Xperia Arc General] Rickette:
Maybe it's because it's fully charged, then it automatically reboots

hey amigo thanks a lot muchas gracias me sirvio perfecto that runs perfect
[Xperia Arc General] JediSchmedi:
1) Is this included in FXP106?

2) I charge my phone during night but when I wake up it says that the battery is around 70-80%. I think this occurs because the battery is full so it stops charging. But is the battery 100% or is it the simulated value?

4.0.2.A.0.62 kernal for xperia neo

hey all devs...

will there be a patched kernal for xperia neo MT15a for the new update 4.0.2.A.0.62
[Xperia Arc General] Bazoocaze:
1)Yes, in CM9.0 RC0. See this:

http://xdaforums.com/member.php?u=3665653

2) In the dead fuel gauge, the battery stops charging when it's full, then begins to drop. On an working phone, it restarts the charge when getting bellow 90%, so if you maintain a working phone connected to the charger it's charge will be between 90 and 100%.

Cant know for sure the exact charge status of battery, because the fuel gauge is dead. We can only suppose that the real charge is at 100% when the charge stops.

It's allready compiled, but it's on my computer at home. Failed several times to upload that here on XDA, so I will try to upload on MediaFire instead.

@for others with FuelGauge v1.6

I carefully analised and tested the working of the new version, and found no flaws on the hardware readings and consumption calculation. This is what I found:

- An USB connected phone (dead or working fuel gauge) doesnt get the CPU to deep sleep state, so if you leave a phone connected after end of charge, it's looses about 3~5% charge per hour only for the CPU usage (additional working hardware, like the cel radio, may render additional battery drop in the time).

- In almost all tests made on my phone, the calculated % value decreased a little bit more than the real value, wich was my object, to make the calculated value a pessimistic reading of the real value. The only case in my tests that the calculated value desyncronized from the real value was using WIFI tethering - I cant figured out how to detect that the WIFI radio was powered in this case.

My recommendations:

- Don't leave the phone connected more time than the necessary for a charge (2h to 2h30 on stock charger, 3h30 on USB). If you leave the phone connected, the CPU will be running all the time, wasting battery charge.

- You can use the CPUSpy app to verify the time running in each state of the CPU. Watch out for the DeepSleep state time. When CPU is in deepsleep state, the phone will getting the maximum battery life from the CPU. The phone can only enter deep sleep when display switched off and no running application/driver.

DoCoMo

Hello i have note to EVRYBODY with locked bootloader :

If you cant use kernel patch from zdzihu for locked bootloader

YOU CAN flash arc with DoCoMo JP firmweare (android 2.3.2 i think)

It will show you 1% battery and will not shutdown so you can use it
[Xperia Arc General] tyrand3:
Bazoocaze, Today my arc is turning off it still have 15% battery and it cant turn on again.

I have problem similiar like this but i have an arc

and i cant get into fastboot/flash mode, when turning on its shutdown again even on usb/ac charging ,every time i turn it on without getting to charging (battery pictures) it blinking red led 3 times i cant charge it too.

I can only go to recovery mode.

my arc condition is:

-repaired from 0% battery 3-4 months ago ,they dont give me a new unit,

i think they just repair/replacing some parts inside.

-lastest doomkernel

-fw .62

-flamemo xperia s themes(v1,v2,v3,v4>installing working app via root explorer)

-never run gingerbreak again since repaired.

Do you think its the fuel gauge problem again?

Or is it different? Can you give some advice?

Thanks,sorry if my word/english is confusing.

Arc is dead?

As stated in my post's subject, i suffer from the 0% error...

I understand that it was my fault, but sincerely, i cannot believe that a software change, no matter it is an update or downgrade, could do that....

So I digged the forums for SOLUTION, just to find this thread, and the locked bootloader patched kernel ftf trio, wich at least in my case, doesn't work...

I managed to flash a mix of a vodafone Spàin and DoCoMo blend, and it reports 1% perpetually, so i can use the phone, but it beeps continuosly with battery warnings, rendering it almost unusable, and can't upgrade if i want to conserve the 1% trick...

Any advice?

Thanks
[Xperia Arc General] ST4YSTR0NG:
This problem really is annoying. My Arc is at tops usable for 2 hours with gaming, a day or two of standby. Sometimes I charge the phone for 2-3 hours and start using it after that, it turns off without warning after like 30 minutes.

I dont think its possible for me to get it repaired by SE Service since there is none in my country (Greenland) and Id like to know if someone knows anything about that.

My Arcs desirability and usability has pretty much vanished although I appreciate Bazoocazes work which made my phone usable at least until I get a new phone (hopefully Xperia S ^^).
[Xperia Arc General] Ofnir107:
Bazoocaze, I wanted to say thanks for coming up with this fix. It stinks that this was my first smartphone, but it was an experience figuring out how to flash roms, etc to solve the issue. Looking forward to CM9. :D
[Xperia Arc General] Bazoocaze:
Sorry, but I can´t do any help for the DoCoMo firmware. I suggest you unlock your bootloader and use the patch.

To see if your fuel gauge is ok:

Enter *#*#7378423#*#*

then "Service info" - "Software info" - look in "Fuel Gauge Firmware Version", if it show an error message, then your fuel gauge is dead again.

Your problem seems to be an empty battery. Try to leave the battery charging for a while (1hour) using stock charger. If this doesnt work, try charging using USB port on PC.

You can also try to flash stock firmware and see if it works. Whatch out for the correct keys to enter fastboot mode and flashtools mode - they are not the same.

It's completely ok to software render the hardware unnusable - it is a brick.

I can´t do any help for the DoCoMo firmware. I suggest you unlock your bootloader and use the patch.

I am sorry for your instability. It seems to be a problem on the system structure. Try to wipe the phone and reflash stock firmware, to see if it works again.

Nice to know this. Thank YOU! ;)

then its turning into charging mode again then dies red led flashing again!

Never ending cycles!

I can go to flash/fastboot mode and i flashing .62 fw using flashtool/seus same neither of them work,flashing you patched kernel can get me into flash/fastboot mode fast(before i've to pressing menu/back button for a long time until its turning to blue/green) but when turning on it still same

By the way, i better go to service center see if my warranty is still apply .

@NEO users

Can someone confirm if the .68 NEO kernel patch is working properly (or isn't)?

Can someone confirm if the .68 NEO ftf firmware linked on first post is working properly (or isn't)?

Kalarox, can you enlight wath combination has worked and what combination has not worked on your phone? Also, can you confirm if your firmware is working (not boot loop) without applying the kernel patch? (I would like to know if the problem is on the firmware or on the kernel patch).

Anyway, it was supposed that the firmware version and kernel version must match to things work properly, so in your case you would like to do a test and try using the .62 firmware + .62 kernel patch, or the .42 firmware + .42 kernel patch. Mismatching firmware and kernel versions can work, but there is no garanty.
