I upgraded my Neo to 2.3.4 from pccompanion for test it, then downgraded to 2.3.2 to enable root and my battery shows 0% charge. It refuses to charge showing always a red light on led. Reflashing to 2.3.4 doesn't resolve problem. Reflashing 2.3.2 and rooting to delete batterystats.bin doesn't resolve the problem.

I tried everything, remove battery, cleaning it, charging via pc usb, via wall socket all night...

I see in Arc forums more people with this problem.
[Sony Ericsson Xperia Neo, Pro] Raoa:
First rule of safety. Don't trust some ftf(or any software for that matter) files put up from china. There are more expert hackers there than you can imagine. Anything might have some little "bonus" code along the normal stuff(doing nothing in your interest), which may break some normal functioning as well. Blind faith and trust will get your stuff broken sooner or later. IF the ftf is in any way tampered it will not work well with your locked bootloader, things can and will break. Use Wotanserver, it's safer but even then... you're not 100% safe.

You tried relocking bootloader and repairing via SEUS?

Get 2.3.3 via Wotanserver before if necessary.
[Sony Ericsson Xperia Neo, Pro] MaxMedia:
remove the battery from phone and reconnect.
[Sony Ericsson Xperia Neo, Pro] Elessar76:
My bootloader is locked. I always used wotanserver to downgrade, so no chinese ftf used. And tried upgrading, downgrading and repairing via SEUS and problem persists.

I removed battery and reconnected dozens of times.

Seems that in Arc forum are more people with same problem.
[Sony Ericsson Xperia Neo, Pro] Raoa:
Ok do you know that you can start phone without battery? I can't immediately find the thread here in XDA. One method was in Motorola Defy forums, using spare USB cable to connect it to phone - and + battery connectors. For other you need some battery juice to get to second bootimage.

Had my defy go into similar state after USB connection failed during upgrade to official froyo... It was deader than dead. Sent it back to shop for repairs.

If you can get another battery you could try if your phone is discovered in SETool and if not then on this thread you can find help to fix bootloader http://xdaforums.com/showthread.php?t=1254409.

To use it you still need a charged battery, so get yours charged or get new.

Did you watch btw how much battery you had left before flashing? Flashing may fail in mid process if it goes below 40%.
[Sony Ericsson Xperia Neo, Pro] yunle:
Hi Elessar, I suggest you to send your phone to SE if you still have your warranty. I had the same problem and SE replaced a new motherboard for my NEO. I saw this issue on a couple of forums and there is no solution yet.

And Raoa, I do understand your concerns, but I think you have worried too much. Most ftf files that I can find on Chinese forums are mirrored from XDA as well as flashing tools, etc. If the Chinese really want your phone hacked, it has already been hacked anyways, because your phone is probably made in China or part of some part of your phone is made in China.
[Sony Ericsson Xperia Neo, Pro] DooMLoRD:
flash any stock FTF

DO NOT power on device

now directly connect to charger (usb or wall charger) for a few hours [make sure that the offline-charging "animation" is seen on screen]

the battery stats will get refreshed
[Sony Ericsson Xperia Neo, Pro] :
flashed the stock ROM

did not power on the device.

directly connected to the wall charger....

but the device powered on automatically and the battery still at 0%.. :confused:

PLEASE HELP!!!!!! I DONT EVEN HAVE THE WARRANTY NOW....
[Sony Ericsson Xperia Neo, Pro] Raoa:
Your logic is incomplete yunle. It's the other way around, a very eager ftf providing comes from China, and these files get mirrored on US/EU servers not the opposite way. Official phone making is not the same as "enthusiastic" providing of unofficial flashing files. 3rdly, trust or not, but always check what is what. Worry and think whatever, thinking can always be wrong. I rather trust an European who puts the source of SE files up along with user made ftf file. Saying anything else is suggesting to "flash away and don't think, all will be fine, nothing bad will happen".

Anyone with this battery problem have you tried relocking bootloader and fixing via SEUS? Try it, if you haven't. It worked for someone in a simliar situation.
[Sony Ericsson Xperia Neo, Pro] Elessar76:
My bootloader is locked by Vodafone and tried to refix with SEUS 3 times, no luck.
[Sony Ericsson Xperia Neo, Pro] Saftawy:
Can anybody confirm that this works, I tried it but as soon as I connect to wall charger the phone auto start!!

Please DooMLoRD Help...
[Sony Ericsson Xperia Neo, Pro] Elessar76:
No, phone autostarts for me too.
[Sony Ericsson Xperia Neo, Pro] nghiemdung:
My arc got this problem too.can anyone tell me which way to get it back normal???:(:(
[Sony Ericsson Xperia Neo, Pro] masray:
I tried，doesn't work。 Plug in the charger and phone starts
[Sony Ericsson Xperia Neo, Pro] rambo21es:
Can someone try this modification of DooMLoRD's advice:

1. flash any stock FTF

2. DO NOT power on device

3. now press back button without release it and directly connect to charger (usb or wall charger) for a few hours [make sure that the offline-charging "animation" is seen on screen] and test if led is green or orange. If it's red, it doesn't work.

4. If it's not red, you can release back button and wait a few hours charging and reboot your phone.

Hello, sorry for my english.

Can you guys try this method:

There is a simple reset button at the back of the phone.

Firstly remove the hull, then see that images:

remove the plastic mask

Then press the button.

I hope that could help you:)
[Sony Ericsson Xperia Neo, Pro] taaviu:
Are you sure it is BUTTON, not plug for ANTENNA....?
[Sony Ericsson Xperia Neo, Pro] NeoJeo:
That's the reset button. You just have to press on the circle to reset the phone.
[Sony Ericsson Xperia Neo, Pro] anikill3010:

[Sony Ericsson Xperia Neo, Pro] NeoJeo:
Sorry. I just give you a solution wich could work. In another forum, someone who cannot turn on the phone, and cannot connect it in fastboot/flash mode pressed this button. The phone reset, and then it was able to turn on, all worked fine. So maybe that could help you.

Sure that's not the same issue, and i'm not sure that'll work but you lose anything to try:(

[Sony Ericsson Xperia Neo, Pro] taaviu:
Sh*t happens!

We dont know is it hardware or software problems.

:) i pressed already about 10x this "button" (i removed sd card and make backup)

and nothing happened....also i removed battery...connect usb pressed agen 10x times...differen methods(knife, neddle etc...) NOTHING.

And there is a CHIPBQ24185

:confused::cool::)
[Sony Ericsson Xperia Neo, Pro] rubenswing:
Seems to me a problem with the DVFS (Dynamic Voltage and Frequency Scaling) settings. SE might have made changes to sleep/wake settings so that they can cater to a wider variety of hardware specs with the 2.3.4 update, but i guess they have made no changes to the boot settings
[Sony Ericsson Xperia Neo, Pro] taaviu:
But if we reflash back to 2.3.2 or 2.3.3 why "old and good" setting dont come back ??
[Sony Ericsson Xperia Neo, Pro] anikill3010:
...

ok, but... the problem start when after downgrading and root the phone :confused: without root can start the 0% batery?

What is the relation between this and the root?:confused:

:confused::confused:

Tomorrow I will go to the service technician to see what he says

I am a bad idea with the matter, sony not like root's phones ..
[Sony Ericsson Xperia Neo, Pro] rubenswing:
That's the part which is eluding me, because this is a software problem and not a h/w problem, somewhere and somehow the settings are being stored "permanently", logically the "old and good" settings should come back after flashing back to a different firmware and this should be evident after booting up but somehow even though the flash is successful to a different firmware, its going back on the old settings....and thats why the 0% after booting up

---------- Post added at 07:52 PM ---------- Previous post was at 07:49 PM ----------

For me the problem is the same like with you, but I did not root the phone, I simply downgraded to 2.3.2 and thats when I encountered this error after booting up.....for me there is no rooting in the equation even though its 0% battery for me and i had no gingerbreak on this phone and did not even do it or root it. :(
[Sony Ericsson Xperia Neo, Pro] taaviu:
I think SE put a virus named "norootanymore" to his 2.3.4 update :)
[Sony Ericsson Xperia Neo, Pro] taaviu:
Then....gingerbreak is not problem....without root your phone is bricked...? Im right? And your bootloader is locked?
[Sony Ericsson Xperia Neo, Pro] rubenswing:
Technically I will not call it bricked, as it was still working when plugged into the USB cable and had to keep it connected to it. And yes the bootloader was locked never unlocked it and gingerbreak .... I did not even use it. I gave it to the SE service center and they said that either they will replace the PCB or they will be giving me a new arc in lieu of the old one.:)
[Sony Ericsson Xperia Neo, Pro] anikill3010:
the problem starting in phones with bootloader locked...

without root no idea, i have a custom kernel...... ( rooted automatically) spain people says start problem with root...
[Sony Ericsson Xperia Neo, Pro] taaviu:
I dont like this :(
[Sony Ericsson Xperia Neo, Pro] rubenswing:
Neither do I but in the end we all are victims of our own consequences...:( but don't lose hope yet, something is bound to come out
[Sony Ericsson Xperia Neo, Pro] NeoJeo:
If it's possible, could someone try unlock the bootloader, (warranty will be losed:() to boot into recovery, and do a Wipe Battery stats/wipe data, by using Bin4ry's Hotboot recovery ? :rolleyes:

http://xdaforums.com/showthread.php?t=1183465

Also ther's other ideas, like flashing CM7, in other threads, here and there.

I tink maybe when the phone gets back to the 2.3.2 firmware, it keeps the 2.3.4 kernel :confused:, so you can try to flash the 2.3.2 kernel, or the DooMKernel if you are in a 2.3.3 firmware.

Good luck !
[Sony Ericsson Xperia Neo, Pro] gosleipnir:
I try to flash CM7,and it is complete.

But battery problem is not solved......

Battey is still 0%..
[Sony Ericsson Xperia Neo, Pro] rubenswing:
For me there is no relation with root, as I never rooted my phone with gingerbreak or anything else. I just downgraded from 2.3.4 and when the phone rebooted I ran into this problem. So i can safely say that i got the problem without rooting, but the main point is I got the problem. So from my point of view the problem is not in root, it has got to do with some settings that the phone is storing and reading it off incorrectly because after every flash the phone should restore the old settings back (logically) and it is not :( .... so I guess somewhere in this grey area lies the problem :confused:.....now this is my view, urs may be different
[Sony Ericsson Xperia Neo, Pro] Sipi1302:
Hy. I looked over the arc forum for the same problem 0% battery and run on this thread http://xdaforums.com/showthread.php?t=1274572, for some people who tray downgrade there's Arc phone this method works and having no problem with battery issue. Try test it all of you who have baterry 0% problem if it works for Neo. Who knows maybe thet solve your problem and post it back.
[Sony Ericsson Xperia Neo, Pro] electricbluejase:
As I didn't downgrade from 2.3.4 to 2.3.2 I have not ran into this problem and from what I have seen that happens with this, I won't be doing the downgrade either, I have root via rootxperia, stock kernel and used flashtool to flash the generic 2.3.4 for the neo, my bootloader has been unlocked with the help of alejandrissimo and apart from overclocking, I have 2.3.4, rooted, bootloader unlocked, so pretty much there should be a warning for people flashing to 2.3.4 to NOT downgrade? am i correct in saying this? as there is something from 2.3.4 to 2.3.2 that is obviously playing up and breaking. 2.3.4 I don't seem to have any issues, wifi worked fine when I tested it and it works nice and fast so yeah. just my 2 cents, sorry for rambling :-)
[Sony Ericsson Xperia Neo, Pro] anhviet030295:
They don't meet the issue just bacause their phone has no problem with 0% battery problem :)
[Sony Ericsson Xperia Neo, Pro] Sipi1302:
I know but the method mentioned in the post for downgrading firmware maybe can solve problem for people with battery problem.
[Sony Ericsson Xperia Neo, Pro] Elessar76:
Not possible. There is not uk.184 firmware for Neo.
[Sony Ericsson Xperia Neo, Pro] Guhrasoh:
I'm not a developer, but isn't there a special flash area where things like the IMEI and Sim/Network locks are stored in? Maybe the new 2.3.4 rom changes something in there that confuses older roms/kernels.
[Sony Ericsson Xperia Neo, Pro] NeoJeo:
Did someone try a wipe data ?

Can you try to flash the 2.3.2 kernel using this method ?

There's also an unbrick software :

I was just playing around with firmwares (long story) and I ended up with the same issue after the latest install. Luckily, all I needed to fix it was to remove the battery and restart the phone.

From the previous posts, I doubt this will be of any help, but if any of you guys is interested on my firmware history, here it is:

Flash Generic UK 3.0.A.2.181 -> Gingerbreak -> OTA to 4.0.A.2.368 -> Flash Generic Nordic 4.0.1.A.0.283 -> Flash to Iberic General 3.0.1.A.0.145 -> Flash Iberic General 3.0.A.2.181 -> Gingerbreak

Yeah I can confirm that your have a bad SD card. I had this kind of SD card before too and it was much more cheaper than original.
