I have exactly this problem too in Xperia Neo. Upgraded to 2.3.4 for test from pccompanion, downgraded to 2.3.2 for root and 0% battery.

Flashing again to 2.3.4 doesn't resolve the problem, flashing 2.3.2 and rooting to delete batterystats.bin doesn't resolve the problem.

Has anyone tried factory reset while charging? If still not solved, try re-lock and unlock the bootloader again. This is a blind shot test but it'll not hurt to try. Seems like 2.3.4 you guys are flashing is the problem.
[Xperia Arc Q&A, Help & Troubleshooting] Elessar76:
Tried a hard reset and no unlocked bootloader here, and 2.3.4 is flashed from SEUS, so not flashing strange 2.3.4 ftf.

Maybe it's silly but after you got the problem you tried to do the official update again via SEUS?
[Xperia Arc Q&A, Help & Troubleshooting] KenTsang:
u can try connecting to the power supply, pull out the battery during the boot process and b4 you see the logo. After that when boot complete, insert back the battery.
[Xperia Arc Q&A, Help & Troubleshooting] icet925:
Someone mentioned that its a bootloader problem on the other thread.

Would you think unlocking it will work??

Man.. they messed up so many people this time.
[Xperia Arc Q&A, Help & Troubleshooting] simonsgray:
Well, i was still in the 30 day return policy with Rogers, so i played dumb and they swapped the phone (nice guys).

I'm going to wait until 2.3.4 is available OTA from Rogers, then worry about rooting. Had enough tomf*ckery for a little while, couldn't believe how stressed i got over not having a phone :|

I did have a couple suggestions for other fixes (that don't require spending money to unlock the bootloader)

1) get a batterystats.bin file from someone who isn't having this problem and overwrite the one in data/system - because deleting hasn't worked.

2) find someone with an ARC that's good and stick their battery in - i opted not to try this as i had a momentary concern that my phone would f*ck up their battery.

the other thing i noticed was that while plugged in, once booted, you can pull the battery and run off usb/ac power. So somebody might want to try:

1) plug in

2) boot

3) remove battery

4) delete batterystats.bin (or 4 then 3)

5) leave the battery out for a while.

6) then either unplug and stick the battery in or stick the battery in and unplug.

i have no idea if that will do anything, but its worth a shot.

Anyway, best of luck to those who are out of warranty. I'm going to keep an eye on this thread.

[Xperia Arc Q&A, Help & Troubleshooting] simonsgray:
in my case it was after gingerbreaking 2.3.2

It must be something that Sony has added with the 2.3.4 update to prevent further rooting with the Gingerbreak exploit, but it's very lame to do it in that way...

[Xperia Arc Q&A, Help & Troubleshooting] grat_master:
I have a few questions :

1- you were all rooted from 2.3.2 generic then 2.3.3 ota ? and then you update it from either that ftf file or pc companion to get 2.3.4. what if you remain there ? no problems at all but no root right ? if you downgraded to 2.3.2 to get root again, now problems occurs right ?

2- OTA is coming from who ? Google, service provider ? I have a rogers arc, unlocked it and using it on telus network, can I still have ota update ?

3- If I still can have OTA update, what if I update it to 2.3.4 OTA when being on 2.3.2 generic firmware rooted and update OTA 2.3.3 ?

wow thats hard to follow :O 2.3.2 ota 2.3.3 flash 2.3.4 flash 2.3.2 to root then ota then flash then root then what ? all f*cked up :O
[Xperia Arc Q&A, Help & Troubleshooting] icet925:
1.) Yes

2.)From Sony Ericsson. I don't think there OTA update yet for 2.3.4.

When you flash to 2.3.4 and stay there, it will be fine. But if you flash previous version and root after that, the problem occurs there.

It's something to do with changes that occurred when flashing 2.3.4

I really hope there's a fix for this. :o
[Xperia Arc Q&A, Help & Troubleshooting] yunle:
I had the same problem.

upgrade to 2.3.4 from 2.3.3 using PCC -> Flash back to 2.3.2 -> root with gingerbreak1.2 -> screwed up!!

I sent my phone to SE and they returned it back to me with the motherboard replaced.

After I got my phone back, I downgraded it again to 2.3.2 HK version, root, OTA to 2.3.4 without any problem this time.

What rom versions of 2.3.4 and 2.3.2 did you guys use when you got the problem? It seems like global version will cause the problem.

The UI of 4.0.A.2.368_HK looks exactly the same as 4.0.1.A.0.283_Global to me. Last time I checked, 3.0.1.a.0.145 was 2.3.3. Did I miss anything?

few more questions, as I don't want to mess up everything.

1- I live in Canada, what is the best firmware to flash to get rooted ?

2- ok, so after flashing that firmware, i root with gingerbreak and ota to 2.3.4, and still remain rooted right ? but I just can't get back to another firmware as I'll get the same problem as you ?

Am I correct ?

[Xperia Arc Q&A, Help & Troubleshooting] icet925:
Just don't flash to the latest 2.3.4 and go back to (previous 2.3.2 + gingerbreak root) = Red LED of death.

Now can we get back to the solutions???
[Xperia Arc Q&A, Help & Troubleshooting] Elessar76:
I have a theory. Rooting with Gingerbreak can show that the battery is at false 1%, so its necessary remove it and put it again. Maybe forgetting this step of the process and battery using up these false 1% to false 0% can cause the problem?
[Xperia Arc Q&A, Help & Troubleshooting] meeaaoon:
it was 1% when i root it and then i pull out the battery without any delay and put back after 10 min almost but it was the same and then i try that again n again then it goes to 0

Hi Guys,

I was on 2.3.3 HK, then I flash back to 2.3.2 global and root with gingerbreak1.2, the same 0% battery happened for me!

I then powered off the phone, remove the battery, remove the SIM (I do not kniow if it was important or not) and then I insert the battery again and turn on phone and then plug the AC cable and the phone start to charge! :) :D

the very important thing was that the battery was 78% charged before the rooting operation and I think that 0% is a software problem!

Try this and tell others if this method work for you!

In my case, they didnt "repair it", but they gave me a new motherboard instead. The technicians at SE customer services dont really wanna spend too much time on one customer. If they think a problem is gonna take long time to check out what is going on, they wont dig into it.

I am sure this is a software wise problem, and it shouldnt cost much money to fix it if one have fully access to the chips.
