I too am amazed its taken so long to get a fix sorted, I would have thought that all that would be needed was a known working ROM and a broken ROM build from someones Phone so that a dev can do a diff.. If I hadn't sent my phone away under warranty I would have offered to be the guinea pig and help with testing. Im sure if the guys who are out of warranty offer to make dontations to the Developer who fixes the problem they may be more interested.. There must be hundreds of broken phones out there now, not a bad little earner if you know what youre doing..
[Xperia Arc Android Development] visarya:
i have hit a dead end and decided drop off my phone at sony service center. they said they will replace the mobo and resturn the device in max 10 days
[Xperia Arc Android Development] Lancerfq:
I'm also getting a straight replacement as my phone is less than 28 days old so thankfully has to be replaced with a new one by law in uk :)
[Xperia Arc Android Development] silentxnl:
I was thinking, if the battery is locked to 1% and you charge it all night.

isnt it possible you blow the battery? as its being overcharged at some point?

---------- Post added at 07:17 PM ---------- Previous post was at 07:04 PM ----------

PS:

I also have the 0% battery, and fixed it with the patch from this thread.

What i notice now on my phone maybe could help:

In a system info application the following variables have been reset to 0000:

Hardware: mogami

Revision: 0000

Serial: 000000000000000000

CPU Variant: 0x1

CPU Part: 0x00f

Battery ah/mah: 00000 none found

Android VM info:

Version: reset to 0

Isnt it possible when you downgrade and have the battery problem all the hardware API's have been wiped?

It cant identify any of the hardware anymore, so cant talk to battery.

i was suprised also the phone serial has been wiped.

IMEI is still present though
[Xperia Arc Android Development] anikill3010:
wtf

the fix worse than the disease
[Xperia Arc Android Development] silentxnl:
This is what i mean.

Maybe when you downgrade and have this problem, the whole hardware API is ****ed.

So the kernel cant access any of the hardware as it should..

Basicly your phone doesnt recognise anything
[Xperia Arc Android Development] Xajel:
I dropped it yesterday night to SE service, they thought first it's a battery problem so they checked another battery.. shorter they said they will call me tomorrow ( which is today )...

I bought it less than 1.5 months a go.. I hope they replace it.. but I doubt that...

I'm missing it :(
[Xperia Arc Android Development] laceex:
I really hope this problem can be solved on this website, not in the service centre... :(
[Xperia Arc Android Development] silentxnl:
Just came back from the service center.

Ericsson has put a new firmware checksum validation in their service center software.

When it detects a customized/flashed firmware you dont have any warranty and they sent you to the door.
[Xperia Arc Android Development] laceex:
this is not a good news what I/we hoped for :S

I have a feeling people with this issue, better to sell the phones as spares/repair, because now almost 3 weeks and still no info about what did caused this problem.

s***ks :(
[Xperia Arc Android Development] jeRrRKKKK:
you can still SEUS update to restore firmware before sending your phone in, am i right?
[Xperia Arc Android Development] Xajel:
Before I send the phone to the service center I already flashed the stock firmware, but with Flashtool and not SEUS... I hope it's still on warranty :(
[Xperia Arc Android Development] silentxnl:
I am wondering if any developer is currently looking into this problem?

Or if this post isnt being handled.
[Xperia Arc Android Development] silentxnl:
Attached my logfile as requested in first post.

Model: Arc LT15i
[Xperia Arc Android Development] jeRrRKKKK:
yes is there any?

btw, i'm a programmer; i'm not well versed with c but i know java

if there is any need for solving code do drop me a message and i'll see if i can help
[Xperia Arc Android Development] meeaaoon:
hey after flashing with battery fix of 1%...

can any one tried to update mobile with pc companion....??
[Xperia Arc Android Development] silentxnl:
Nah, it says the software has been modified so cannot update.

Due to the unlocked bootloader.

I wanted to execute the OTA update to check if the 0% goes away.

But i dont want to try locking my bootloader, and shooting myself in the foot when it blocks everything else.
[Xperia Arc Android Development] shahzaib.khan:
Hey i can update from pc companion but the problem still the same 0% bettery.....n shutdown.....i dont know why no one is telling the estimated time to resolve this problem ....there are good developers here in xda but no one is replying on this thread for solution or any thing.....i will wait few more days if the solution will not be available unfortunetly i have to sent my cell to the warranty service and they took atleast 15 ****in days aaaaahhh common developers plz do sum thing i dun want to spent 15 days without my cell :s
[Xperia Arc Android Development] meeaaoon:
did you tried that after fix or without apply fix....??

I if you have warrenty then dont wait just claim it cz there is no estimation about that solution and even SE guys cant resolve with software....
[Xperia Arc Android Development] shahzaib.khan:
I updated after patched 2.3.3 bettery fix....there is a thread on 3 or 4 page which have a link of that patched rom.....ahan oki i will claim it on this week end...
[Xperia Arc Android Development] icet925:
I have been able to use the xperia arc as normal with the battery patch.

It just shows 1% battery all the time.

I believe that it is able to charge the phone because it has never ran out on me yet.

I have been using it for 4 days now.

However, I am sincerely waiting for a full solution.

This is my log_out.txt after the battery patch. Hope this can help.

Thank you.

P.S. It might sound stupid, but maybe we can use this to compare with a fully working device?

[EDIT]

My phone is definitely charging.

The line:

chargalg chargalg: Trying external again...

is gone after the battery patch.

After the patch:

power_supply bq27520: driver failed to report `voltage_now' property

this didn't show without the battery patch.
[Xperia Arc Android Development] icet925:
Again, restating what has already been said...

"The Texas Instruments bq27520 system-side Li-Ion battery fuel gauge is a microcontroller peripheral that provides fuel gauging for single-cell Li-Ion battery packs. The device requires little system microcontroller firmware development. The bq27520 resides on the system’s main board and manages an embedded battery (non-removable) or a removable battery pack.

The bq27520 uses the patented Impedance Track algorithm for fuel gauging, and provides information such as remaining battery capacity (mAh), state-of-charge (%), run-time to empty (min), battery voltage (mV), temperature (°C) and state of health (%)"

This should be the culprit.

That should be why SE insists on replacing the mobo because it is attached there to manage the battery.

If we can find ways to repair this driver, we should have a chance.

the_laser was on to this so please give this a read if you are interested.

[Xperia Arc Android Development] shahzaib.khan:
Aahh these all things are so freakin me out im gonna send my ArC to warranty service....
[Xperia Arc Android Development] shahzaib.khan:
By the way anyone know what SE will do if i will sent my cell to them?
[Xperia Arc Android Development] taaviu:
Repair? :)
[Xperia Arc Android Development] Xajel:
I called them yesterday after I finished work @ 17:45, they told me the phone is ready and I can come and pick it.. I was surprised as it didn't take long... the problem I cannot go there as they close at 18:00 and I need at least 20 - 25min to reach them...

So next day I planned to take it... they called me about 10:00 and confirmed that the phone is ready and I asked the guy what was the problem, he said the motherboard was damaged so he replaced it with another one... I tried to convince him about replacing the phone but he said the phone is older than 1 month now and more importantly there's a scratch on the housing.. so he can't replace it...

I went and received it normally and every thing is working nice now, except that replacing the motherboard made the market think this another android and I need to install apps manually ( thankfully all apps are listed in the market already )... I tried to use MyBackup app but it says I need to buy the Pro version duo to the fact I changed the phone ( which I didn't but the motherboard is different now, so technically this is another phone )...

now it's not World Generic as it's a local firmware again, and it still on 2.3.3 and I lost root :(
[Xperia Arc Android Development] silentxnl:
Dear Xajel,

Was your phone's bootloader unlocked?
[Xperia Arc Android Development] ToMmY_hun:
What do you think? What should I do? Take my phone to the warranty service or wait 'til somebody find the solution?
[Xperia Arc Android Development] uyo_kun:
is anyone can patch the .368? because I need to use XLoud and the other...
[Xperia Arc Android Development] Xajel:
No, it was locked...

If it was unlocked I wouldn't count on warranty
[Xperia Arc Android Development] shahzaib.khan:
solution solution solutionn.where iss solutionnnnnnnnnnnnnnnnnnnnnnnnnnnnnn ?:P
[Xperia Arc Android Development] Duvel999:
I'm wondering..How may phones are broken?

:confused:
[Xperia Arc Android Development] Kifsito:
I've wondered that too, i keep fighting my urges to update my phone since 2.3.4 smells of danger and who knows what kinda payload did SE embed into it.
[Xperia Arc Android Development] FiDra:
May be a hundred of broken phone are out there :D

We are left behind :(
[Xperia Arc Android Development] ToMmY_hun:
If you have warranty, use it! They'll change the motherboard and your phone will be OK.
[Xperia Arc Android Development] silentxnl:
Too bad my bootloader was unlocked.

i hope someone will still try to find a solution for this.
[Xperia Arc Android Development] ToMmY_hun:
A developer from SeTool is on it. Hope, he can find the solution...
[Xperia Arc Android Development] rubenswing:
Yep that's what they did for me...got mine yesterday after it was replaced
[Xperia Arc Android Development] Nirak:
can't you try to lock bootloader:

http://xdaforums.com/showthread.php?t=1134335

and then send it in for repair? maybe..just maybe they don't look any further then first level to check bootloader
[Xperia Arc Android Development] migsguerra:
replace the Unit or parts ? Ruben ? cause i sent also mine in store to repair
[Xperia Arc Android Development] rubenswing:
They replaced the motherboard...so technically its a new arc now :D
[Xperia Arc Android Development] silentxnl:
I could at least try :-)

They told me last time they do a checksum check of the boot partition.

So this might work, we will try.
[Xperia Arc Android Development] silentxnl:
Great news!

If you relock the bootloader as per the above post you get back your warranty.

The ericsson service center validated my phone's checksum!

i advise all to do the same asap.
[Xperia Arc Android Development] meeaaoon:
ohhhhh :((((

for a moment i thought that the solution arrived... :(

thats not Great for me Got no warrenty...

waiting for solution...
[Xperia Arc Android Development] damogran:
same problem here.

hope for a software based solution

thanks for any help and for the workaround patch.
[Xperia Arc Android Development] icet925:
It's no great news until there's a solution.

It's kinda just rubbing it in for those who cannot get the warranty. :o

I hope devs are still working on this.

I am willing to donate if someone come up with a solution.
[Xperia Arc Android Development] damogran:
word!

same here
[Xperia Arc Android Development] silentxnl:
Bro, the SE shop also said i didnt have warranty due to the bootloader unlock.

but if you use this fix, the SE shop says you DO have warranty....

Now they accept my phone, before they sent me away.

im not rubbin it in yr face, im telling you guys to follow my path as i got back the warranty with this fix
[Xperia Arc Android Development] icet925:
Sucks to be me then,

I bought my phone else where/ out of country.

So no warranty for me.

No matter locked bootloader or unlocked bootloader.

But I don't see why they would not take it in the first place if you relock it.

So, it's not terribly great news..
[Xperia Arc Android Development] shahzaib.khan:
The great news only will be consider if there is a solution of this ****in prob other wise every thing is a suggession.....
[Xperia Arc Android Development] heidality:
have anyone fix this problem?

the laser stop work to solution this problem
[Xperia Arc Android Development] silentxnl:
If the dev's stop working on it, i fear its a genuine hardware problem which cant be fixed through firmwares.

Although the problem is caused by the software, when it should be reversible.
[Xperia Arc Android Development] Bin4ry:
Well let me jump in here:

I read up some informations, maybe you can help me work it out.

From what i know the problem occours:

- On downgrade to a "too" old version

- Intention of downgrade was to use gingerbreak

- Problem does NOT happen when you downgrade step by step in versions

What i know:

- TI Fuelgauge firmware got a firmware-update around the problematic firmware you are downgrading to.

Assumption:

Firmware 181 had included the firmware upgrade of TI fuelgauge. When skippinmg 184 firmware in downgrade process you are running into a firmwareupgrade which fails.

As result you will end up with a ****ed up firmware!

Similar problem we had on X10 some time ago, but on X10 it was camera firmware which got upgraded.

Ok. Here is the plan:

Because i am busy in fixing hdmi i have no time to crossflash all firmware versions or extract it. Just too busy sorry.

But you can help me.

Please dump me the filesystem (exclude apps!) from 184 and 181 firmware! I think we can find some informations inside which helps to repair the firmware of the fuelgauge ;)

Regards
[Xperia Arc Android Development] damogran:
dunno how to dump filesystems but know how to donate, have fun with the beer! ;)

thanks for offering your help!
[Xperia Arc Android Development] FiDra:
Finally, Cyanogen team has involved.

Thank you so much, Bin4ry :)

I will search around to know how and dump the filesystem for you.

---------- Post added at 12:08 PM ---------- Previous post was at 11:51 AM ----------

Hi Bin4ry,

I found this:

Firmware 3.0.A.2.181 [retail]:

http://www.fileserve.com/file/B5PtdEV

(Source: http://xdaforums.com/showthread.php?p=12109695#post12109695)

Does it is what you want?

I did not find the 184 yet.

Can you tell me how to dump the file system of an arc firmware. I got 181 and 184 firmware (used to flash with FlashTool) but don't know how to dump it.

Hope to hearing from you soon.

Thanks!
[Xperia Arc Android Development] heidality:
you help us to find battery problem fix?
[Xperia Arc Android Development] FiDra:
I think he said very clear in his reply, heidality :D
[Xperia Arc Android Development] SubK:
I think he meant, you have to flash the ROM, then use ADB and tarball the /system on your phone.....

Both .181 and .184 /system so he can compare what is changed in the downgrade/upgrade process. Correct me if i'm wrong...
[Xperia Arc Android Development] heidality:
ok.and no one help?we must go to service this is only way to solution?

---------- Post added at 05:14 PM ---------- Previous post was at 05:11 PM ----------

you are right
[Xperia Arc Android Development] uyo_kun:
Well, if you can patient for a while, just wait the developer to solve this problem. Use the 1% patch if you want bring it to somewhere you want. And, if you can't wait, go to SE to repair it.

Cheers,

uyo_kun
[Xperia Arc Android Development] FiDra:
Hi heidality,

What is "tarball the /system on your phone....."?

What command should I run with the adb to dump the filesystem?

Please advice! I'd like to help, but don't know how to do :)

Thanks!

[Xperia Arc Android Development] shahzaib.khan:
Pleaseee any one any help him to fix fule gauge :p.cuz i dunno nothing about this dev thing :p...
[Xperia Arc Android Development] icet925:
Thanks B1nary,

I think you are correct on your assumption.

It cannot be a hardware issue, if it works on the 1% battery patch.

I will see if i can find them file you need to fix this.
[Xperia Arc Android Development] Bin4ry:
Please do :

adb pull /system/. C:\yourdir\system\.

adb pull /. C:\yourdir\root\

adb pull /etc/. C:\yourdir\etc

for both 181 and 184 firmwares. This would help me to help you ;)

If you are not able to do i have to do it myself. But this may take some more days, because i want to workout hdmi for CM first.

By the way with that battery patch I am working already more than week and it's all right I mean when phone should normally turn off it don't so it is quit useful....
[Xperia Arc Android Development] Poker gypsy:
That's why I don't root my phone anymore
[Xperia Arc Android Development] :
You can root your phone safe if you do that in recovery mode using flashtool.

True, but only if you have an unlocked bootloader.

[Xoom Android Development] stachre:
Yes. I suggest using this update only if you wish to have stock ROM and stock kernel with root.

EDIT: updated OP for clarity.

MORE EDIT: You can always re-flash a custom kernel after the update.
[Xoom Android Development] shakuyi:
have you noticed any changes from 3.2 to 3.2.1?
[Xoom Android Development] i_am_the_one:
Worked great, thanks
[Xoom Android Development] stachre:
I haven't been using it like a normal user yet, so I haven't noticed any differences. It's a small update, though, with the following files having notable patches/updates:

Bootloader

Recovery

Boot image (kernel 2.6.36.3-g111d827, also corresponding small update to bcm4329.ko)

/system/etc/security/cacerts.bks (probably response to DigiNotar debacle)

/system/framework/bouncycastle.odex

/system/framework/ext.jar

/system/app/NetworkLocation.apk

/system/lib/libskia.so

/system/lib/modules/bcm4329.ko (tiny update, probably due to new kernel)

In addition, a slew of system APK's, framework JAR's and ODEX's, and other miscellaneous files got touched, but the patches were so small that they're likely just version updates or minor bug fixes.

An official changelog (if we get one) would provide further clarification.

EDIT: HTK75D notable file updates:

Recovery

/system/app/Phonesky.apk (new Android Market 3.1.6)

/system/app/BooksTablet.apk

/system/app/BooksTablet.odex

/system/app/Music2.odex

/system/app/SystemUI.odex

/system/app/SystemUI.apk

/system/app/VideoEditorGoogle.apk

/system/app/VideoEditorGoogle.odex

/system/app/Videos.apk

/system/app/YouTubeTablet.apk

/system/app/YouTubeTablet.odex

/system/framework/ext.jar

/system/framework/framework-res.apk
[Xoom Android Development] BigBadBuddy:
Just trying to be clear, sounds like this will update without effecting existing configuration and install. Is that correct?
[Xoom Android Development] i_am_the_one:
Yes data was not touched, everything was the same as before the update.
[Xoom Android Development] BigBadBuddy:
Thanks!
[Xoom Android Development] BigBadBuddy:
One more thing. Did you flash Tiamat or any other custom kernel over this? Just wondering if the bootloader update in the new Tom would hose my Xoom with a different kernel.
[Xoom Android Development] BigBadBuddy:
OK, just did this. Flashed this ROM, booted, rebooted into recovery, wiped cache and dalvik, flashed Tiamat Tachi, booted. Done. All good.
[Xoom Android Development] i_am_the_one:
I did not flash a custom kernal. I was running the rogue kernal before the update though. Have you noticed any issues running the tachi kernal? I would love to go back to overclocking, but I wasn't sure if the kernals would play nice with 3.2.1
[Xoom Android Development] tincbtrar:
Test it. Make a nandroid before you do so and give it a shot for a week.

Looks like that would break the bluetooth mod that was created though :(

Let us know how it works. I like the rogue kernel a lot.
[Xoom Android Development] BigBadBuddy:
Tachi works great. I'm typing this on my bluetooth keyboard (the only bluetooth device I have to test with). I'm going to test with Rogue later today. My concern initially was with the boot loader update on the 3.2.1 ROM. On the first kernels that I fflashed on my Xoom, there were custom boot loaders. I think they were only for charge lights onn/off, but wasn't sure. I'm pretty sure that any 3.2 compatible kernel will work with 3.2.1. The update was pretty small and mostly bugfixes from what I understand.
[Xoom Android Development] i_am_the_one:
the rogue kernel aborts before flashing I think due to version checks. But I flashed tachi , so we'll see how that works.
[Xoom Android Development] tincbtrar:
@bigdaddy I meant the Bluetooth tether feature. I imagine all else works great.

I installed this today and its great so far - thanks for your contribution.
[Xoom Android Development] tincbtrar:
You should be able to modify the installer script to look for 3.2.1 :)
[Xoom Android Development] shakuyi:
does this update have a new market?
[Xoom Android Development] i_am_the_one:
Looks the same to me 1.0.28
[Xoom Android Development] BigBadBuddy:
Oh, got it. No problem. I haven't tried the bluetooth tether. Did you try it yet?
[Xoom Android Development] lexus470:
Thanks ...
[Xoom Android Development] tincbtrar:
I havent tried it because I flashed Tachi right over it. I wanted the ability to overclock and I dont use bluetooth tether. I wouldnt mind having it as an option in the future on Tachi...but no bigs.
