[Q] Xperia GO Battery - Sony Xperia P, U, Sola, Go

[Q] Xperia GO Battery - Sony Xperia P, U, Sola, Go

Hi! Can someone guide me into removing or getting access to the battery of this unit. I think the kernel is corrupted coz I think I flashed the wrong one. The battery drained out. So without a working kernel, I cant charge the phone. Even in USB to PC or directly to wall charger. I want to re-insert t the battery to see if that fixes the issue.
Can someone tell me if removing the battery then plugging in the usb without the battery if I can enter flash mode or flash boot to be able to flash the correct kernel or go back to stok room for the phone? Would that work?
Or I just need to reinsert the battery then try to enter flash mode?
SITUATION:
- cant enter flash mode or fast boot.
- can hard reset (Power + volume+)
- Cant turn on the phone
-just red led when plugged in then disapperas after a few minutes (not charging)
- the phone never got wet or never been dropped. (so im hoping this is a software issue)
- phone is rooted, unlocked BL with CWM.
-started when I flashed a flshable version of CWM touch version to upgrade from version 5 to 6.
Help please. Im thinking of opening the phone to access the battery.

The idea of removing non-removable battery is not the best one, unless you really know what are you doing - and i don't think you know it.
And i think this won't help you, really not.

You can hard reset - but battery is drained?
Once, i had problem like this one, but i managed to get into fastboot and re-flashed right kernel.
What were you exactly doing? Rooted and BL unlocked Go? What and how were you flashing (which rom and kernel were you flashing)?

sorry just a typo error, i mean i cant hard reset. I know how to access an embedded bat, tried it before with Xperia S. but I was hoping if can flash without doing that anymore?

Managed to disconnect and reconnect the battery; however I still cant turn it on, or even hard reset, or flash mode or fast boot. Crappppp! help. What can I do to bring this phone's life back. I flashed an update for CWM on recovery. Thats when this problem started.

any help out there?

Same problem

Hi, i am having the same problem. I flashed the kernel for another model out of noobness. So removing the battery did not help at all?
OMG right as i was typing this, the rubber band trick worked and i accessed fastboot and flashed another kernel. It wont start for now, but maybe the battery needs to be charged for a while (red led). In case you dont know (if you still have this problem), i will explain what i did (the computer just detected the device, so i think im in the clear):
1) get a rubber band and put it around vol up button (this is for fastboot; for flash it would be vol down)
2) plug the phone to your computer
3) get the fastboot.exe file (google)
4) put the correct boot.img file (or kernel, i flashed the wron boot.img, so i did it this way. I dont know what the difference is) in the same folder as fastboot.exe
4) open command prompt, go to the fastboot folder (look up commands)
5) type in "fastboot flash boot boot.img"
6) the cmd will say "waiting for device..."
leave it like that; i got purple (i guess blue plus red) led after awhile and fastboot flashed the kernel.
I will keep you informed on success or failure.
EDIT
It worked, i have a running phone.

Hey! Thanks for the post and reply, would have done that. However, i sent my phone to a repair center, and they havent got bakc at me until now, its been 3 weeks.
Was your phone unable to go fastboot and flashmode too before? And when you charge it red led appears then goes away after a few minutes? My PC cant recognize the phone, the only indicator i had was the red led when plugged in which goes away after a couple of minutes.
How long did it take for the phone to enter fastboot? Coz, I've tried holding the button (Vol+) for almost 5 minutes and nothing happens.
Can you provide me the exact situation you had? and the clear cut steps you took to fix it? Especially how many minutes for it to go to fastboot with the rubber band on?
TIA!

@ madismet
your rubber band technique actually worked!! thanks a lot!
I was just about to give up on my xperia go, when I came across your post...
thanks!! :good:

[Q] Atrix stuck on Moto bootscreen, unable to enter CWM recovery

I'm pretty new to the whole flashing business, so if whatever I asked does not make sense, please be patient. Thanks!
I recently flashed the Neutrino Rom V2.6 from V2.5p2. Got lazy and didn't do a full wipe before flashing (also my battery was at ~5% ) After the installation, I successfully booted into Android, but realized that the fresh ROM didn't have multilingual or sync support (since the Neutrino Rom is a stripped down CM7), so I booted back into recovery (still with low battery)
I subsequently flashed the addons provided by the dev for multilingual and sync support, and when I selected "Go back" in CWM recovery, it displayed a long string of error messages, I believe starting with E:\"........."
Ignoring the error messages, I selected "reboot system", hoping luck would be on my side, but it wasn't
the result of all this is is that I can only "turn on" the phone with it plugged, and it will go through loops at the Moto bootscreen...also if I try to enter recovery by pressing "power+vol down", the screen goes blank and does not enter CWM recovery. Further, I am also unable to charge the battery for some reason, because as soon as I plug the phone into the wall charger, it will go through the Moto bootloop
My question is, is this a hardbrick or softbrick?
If it's a softbrick, is there any way of fixing it, or has somebody else ran into a similar problem?
Please help me out here, like I said, I'm new to the whole world of flashing stuff, so much advice is needed, and any help would be appreciated!
Thanks a lot ahead of time

Before you begin, turn OFF phone, remove battery, and connect to wall charger charger. When ? appears, install your battery and let it charge for a long time. NEVER FLASH WITH LOW BATTERY!
You need to reflash your recovery. Before you start, perform a proper WIPE. SKIP THE FIRST 4 STEPS, read this:

When I plug in the phone without battery, it just goes to the Moto boot screen, and starts the loop again...the usual "?" symbol doesn't appear at all
I've done battery calibration before, where it was required to plug phone into wall charger without battery, and the "?" has always appeared

Try getting to that menu and let it charge for a while? Have you tried that? ANd I mean, let it charge for about an hour. Charging might take longer than usual because your screen will be on.

update: charging on the fastboot screen now - the battery is a little warm, that means it's getting charged up?

It is possible, but remember your screen is on.

Sent from my MB860 CM7 olympus latest nightly 30p Radio. Leave your charger at home!

sorry for the late reply...and thanks for all the help
no actually am not, I still can't get the battery charged up, which is the biggest issue right now...
I think if I can find someway to charge the battery without plugging in the phone, it's possible to enter fastboot with a charged battery
otherwise, even if I get to the bootloader menu (fastboot, nvflash, recovery etc etc), when I plug the phone into the computer and select fastboot, it'll still say "battery too low to flash"

Just a suggestion...trying to help. What if you find out a fresh charged battery before starting the recover procedure? I dunno if it will work because I dunno if there is some kind of serial number checking at this low level in the phone....I see that under no circunstances could you charge your battery again...

Borrow or buy a battery. Or make a new thread asking how to charge battery. Title on the thread is misleading.

i use this method n it worked thanks..to bad my wifi still shows up error after i attempt to connect it it doesn't reboot thats good i think

low battery
Even i am stuck in recovery. No matter how many times i flash a ROM after wipe data/ cache partition and dalvik and then install the ROM i still boot into recovery when the ROM asks to reboot the device.
Here's what happened
1. Had a nandroid backup of older version of CWM mostly 5.0.2.x
2. Based on Nottachtrix thread installed the romracer recovery(updated flashable zip)
3. Updated to Nottachtrix 1.3.1 and successfully booted
4. Figured out that contacts everything weren't synced. So wanted to go back to older CM7 rom using restore ROM
5. Something went wrong during restoration. Data and other wern't restored and i guess only boot had been restored
6. Endless loop into recovery thereafter.
Trying out different things like flashing boot.img, recovery etc battery drained and couldn't flash.
Fasbtoot and other options triggered by using volume buttons and power button works fine. RDS also detects the device but bootloader unknown and other info all were unknown.
Since battery drained i was searching on methods to charge the battery. Had figured out that custom method for charging the phone needs to be implemented.
While playing around again with phone i powered it through directly through charger and opted for linux cold-booting which gave me the battery icon with the question mark on screen. Popped in the battery and it started to charge. So now i know i can charge the battery using this method.
I am yet to make progress on flashing ROM successfully again. Is my backup lost ? Did the error happen because i backed up using an older version of CWM or flashing to Nottachtrix changed something
I even restored successfully to my previous ROM after deleting .android secure from ext SDcard but still it threw me to CWM only :|
Help appreciated.

xperia p no charging lights, no usb detect,does not boot (not even the kernel screen

hello everybody,
i used to be active on the x10 forum.
but recently i switched to xperia P.
i unlocked the bootloader,
used fastboot to flash custom boot.img,
fastbooted custom kernel (FreeXperia),
installed cm10.zip with the CWM included in kernel,
everything works except wifi and bluetooth (which i guess is the rom's fault, so i dont really mind)
and then i installed apps from the cm10 file manager.
it detects my 16gb internal memory.
but my titanium backup and some other apps says it cannot access my internal memory, so it doesnt show any apps. (usb is disconnected)
so i thought mayybe some apps dont have access, so i thought i should mount my internal memory (although it already works for my cm10 file manager).
that was a very stupid decision because i used this code from this website which i got after i googled and used it on my terminal emulator.
guess what happened? my device got stuck/hang/frozen.
then when i pressed the power button, it was totally blank, no response and the screen went off.
i tried force shutdown by pressing and holding the volume-up & power button at the same time for a long time, that didnt work either, it had no effect, there was not even a vibration.
and when i charge it, there is no charging light.
it doesnt boot, it doesnt show me the kernel screen, or the CWM screen.
this is worse than a bootloop.
anyone who has previous experience with this?? or has a suggestion on how to repair?
any advice will be much appreciated :crying:

I think you've posted in the wrong forum - should be in Q/A.
Is your phone able to detect in flash mode? (while it is off, hold DOWN volume key and connect USB - check for LED illuminated)
Is your phone able to detect in fastboot mode? (while it is off, hold UP volume key and connect USB - check for LED illuminated PURPLE)

Hi.
1. Have you tried to charge it through the charger, instead of the usb por of PC?
2. If you tried, did you let it charge for at least 30 minutes? (Sometimes the battery drains so much that the phone needs time even to show it´s charging.)
If the battery charges, you should try flashing a Stock Rom through Flashtools.
If it doesn´t, then I can´t say you should do it but if I were in ur position, I would surely open my phone and try to charge this battery somehow. Google a lot to learn how it works, the wires, what is positive and negative and bla bla bla because your biggest problem NOW is not having power to work with the phone.
Hope you have good luck!
=)

Sorry please post your thread at Q&A

Use this guide to open the phone up and just disconnect the battery for a few minutes. Then try connecting in either fastboot/flash mode. The phone may need to be repartitioned and reflashed.

Same issue
Hi Davin-J
Did you finally solved this problem? I have the same now. And my battery should be good.
...............................
1/2 day later:
It was the battery. I managed to get it back to life as copper62472 told us. The strange thing was, that the Sony charger didn't charge the phone battery; may be because I bricked the phone before with system/data/cache wiped and formatted. I was not even able to restore it with SUS, because the phone was not detected at the USB.
Then I charged the battery outside the phone with a current limited power supply. After putting the charged battery back into the phone, restoring with SUS worked without a hitch.

My xperia p is also in dead condition now. I'm thinking like it's battery is fully drained. It all started with flashing of a custom kernel.
i could take the battery out. i need to charge it by external means. How can i do that? Please help me.

[Q] Xperia pro not enter flash(or fastboot) mode. LED blinks only...

Hi guys,
I have mk16i(xperia pro), and installed latest lx cm11 build. Then, I tried dark's kernel. But I wanted to revert to the stock kernel.
Now at that point, i couldn't enter the fastboot or flash mode anymore. The OS running w/o any problem. But i'm stuck with the dark's kernel(which is very battery unfriendly,10 hour standby)
When i try to connect the phone to PC while pressing menu(or back button) the LED blinks for miliseconds and the phone continues switching on normally (enter OS).
I know it is my fault to install nonstock kernel but I really need help. If anyone experienced this issue, it will be great to hear the advice.
Thanks in advance

Try taking out the battery for a few seconds, reinserting it, pressing the button for fastboot mode (I don't know which one you have to use for the xperia pro) and then you connect it to your PC while keeping the button pressed. This should work

Thanks for the reply.
I tried it many times. But no chance... The LED blinks then the phone goes into OS.
I tried to reboot fastboot via adb commands. Again same result. Directly goes to OS.
Flashtool also stucks at "Device will soon enter fastboot mode" nothing happens. Phone stays on...
Is it hw fault? I will be very disappointed if so I replaced its digitizer recently by paying too much money.) It was expensive when i bought it also... I cant stand buying a new phone these times... pff too many issues...

Sounds weird. I have made the experience that it sometimes helps to take the battery out, then keep pressing multiply and long the power button. Wait ~10 minutes. Insert the battery and try again!
Hopefully it helps!
Otherwise could maybe be kernel related. Try to flash another one (with recovery).

We are not able to flash kernel thru recovery in XPeria devices i think.
That is the main problem actually. I m stuck with this kernel...

i think you done it allready but better than have adead phone:
- re check if all drivers installed (android sdk with its google driveer, flashtool drivers)
put out battery , put in & hold volume down while plugging cabel in. (if led not stays blue, pull out abttery, put in & reconnect but hold other button like menu key) --> try all buttons
i cant imagine flashing darks kernel broke yr bootloader. theres sth wrong with your machine / setup / whatever.

If nothing works, you can still "emergency" flash a stock firmware with SEUS, or not?

if he unlocked his bootloader DONT USE SEUS! --> you get a brick...
use flashtool to flash stock ICS ftf .

Thanks for the answers. Yes unlocked bootloader.
Since the device doesn't boot into "flash" mode also, i am not able to flash ftf through flashtool or any firmware via SEUS.

I had managed to enter fastboot mode once!
Happened with USB3.0 port via "adb reboot-bootloader" command.
Still, I am not getting into fastboot again...
I will inform you, thanks guys.
EDIT: I did it once again thru adb in recovery and flashed a stock kernel. Let me see the battery drain is due to kernel or some hw damage.
I am sure hw is damaged...

Ultimately solved...
After i am able to enter fastboot mode via some funny method described above, i erased system partition and flashed kernel.sin of the official .587 ftf file of Sony Xperia Pro.
Now the device is able to enter flash mode and fastboot mode via normal ways...
Thanks guys...
EDIT: I dont understand how is it related to kernel? I thought that bootloader files are damaged which i cannot correct them.
There are many .sin files in the stock .ftf which i cannot flash any of them without flash mode.(i was able to enter fastboot mode only)

The problem started occuring again. LED blinks again.
This time i am not able to enter fastboot via adb while in recovery mode or another mode. I can't enter fastboot or flash mode, cant install kernel. Tried two pc's many usb cables...
I don't know what to do...

Guys please help. I am very confused now: When i connect the phone to charger(AC) when the phone is OFF, the phone tries to enter flash mode!?! Led blinks green then the phone continues to open and offline charging animation comes as usual.
Sometimes the phone connects the charger in flash mode! But doesnt connect to usb in flash mode or fastboot mode. I know it is a bit confusing but that is the situation.
Thanks...

[Q] Booting Problems! [SOLVED]

For reasons unknown, I'm able to boot into flash mode and therefore restore my ROM.
Thanks for helping me though, random stranger!
So can anyone close this thread? It isn't needed anymore.
I recently flashed a new stock pure Lolipop ROM on my Xperia Z Ultra from a stock pure Kitkat ROM that I've been using for months now.
However, it is noteworthy that my device has been rooted and custom roms has been installed on this device for about a year now. So my device has its bootloader unlocked.
I followed all of the instructions I can
- Wipe the data and cache ( incl. dalvik )
- Flashing the ROM in question
- Flashing the su and GApps
- Wiping the cache ( again, just to make sure )
And here's where the problem started
When I started to boot my smartphone, it flashes red for a couple of times. At first instinct, I thought it was a battery depletion problem, and sure enough, it was! So I plugged in and noticed yet another problem; my phone started randomly turning on for a brief moment before shutting back down, presumably due to extremely low battery power. And it didn't even bother to wait for my Z Ultra to be charged to a reasonable level of power before attempting to power on. However, I tried using the power+up button fix, and it didn't work and then there's yet another kicker; Fastboot ( Blue LED ) Mode is no longer accessible on my phone. When I plug in while pressing down on my ZU, it does nothing and simply just charges ( presumably ).
I'm currently on my last legs of hope and doing the last resort: to wait for my smartphone to charge substantially enough for a long time.
Which is about 8-9 hours after this post is made.
TL;DR
- Device is currently rooted for a year now and has been installed with custom roms left and right.
- I followed the instructions to the T
- Phone not able to turn on
- When charging, phone attempts to turn itself on, regardless of power level
- Plausibly due to low battery level 15%-24% during flashing
- Fastboot Mode not possible presumably due to low power
- Now waiting it out for 9-8 hours to see if issue resolved
- Will update whether if method works or not
Please help! This is one of my most used smartphones.

Yeah, it might be the battery that's gone bellow the "zone". What I mean is when you deplete the battery completely to 0%, there's still more battery left, but the system shuts it down so not to damage the battery. It's a Li-ion thing. But once in awhile it does happen that it get completely empty, and you'll experience what you've done here. A dead device. It's not only Sony phones that experiences this, but from all OEMs.
Notes:
- So, keep it charging for 15-20 hours and see if it helps.
- You mentioned fastboot not working. Be sure to have fastboot installed on the computer. If it's not, it won't work.
- Blinking red LED also (usually) means there's been a kernel panic

Just flash a different kernel. If that doesn't solve anything, then we'll know that it isn't a kernel panic.

We've got Fastboot and Flashmode. Fastboot is what you use when you want to flash some ROMs and kernels through a terminal (command line), while Flashmode is for flashing ROMs in Flashtool and Sony's PC Companion.
You can enter Fastboot by holding VOL UP while you connect your device to the computer. Remember to hold VOL UP until the LED above the screen turns blue. Once you've achieved that, the either flash/hotboot a kernel with recovery, like NUT's Dual Recovery, and then restore or flash a different ROM. If the device doesn't reboot by itself or do anything weird, then case closed. If it does do something weird, then I'm not sure what's going on.
Remember to have fastboot installed on your computer. Or else it won't work. You can easily install it by using this installer. If you don't know how to use fastboot through a command line, then use Flashtool or QuickIMG.

Bootloop and battery won't charge

so i was flashing existenz MM and i can't go to recovery mode, before installing it i have xzdual recovery installed, so i thought i can just flash it again (and ofc it was stupid because after that i just know xzdual won't work with MM) so it's bootloop even when i charge it, the problem is the battery died and it won't fill the battery, the phone keep restarting when plugged in with charger so it keeps draining the battery before it filled up, i can't flash it because of that, the question is, how can i fill the battery so that i can flash it using flashtool?
thanks, and sorry if my English is bad.

If there is no other way you can always open the phone and charge the battery manually(if you have the equipment to do that). I had to do that to my phone yesterday(my battery was so low that it wouldn't boot).

You have to use a hairdryer. There are tutorials on YouTube.

The phone should also be able to charge in recovery. Try that.
Btw. I recently flashed a Z2 via flashtool with an unplugged battery (usb power was enough), so you could also try flashing it now although it's empty.

Thank you for the reply,
but the phone cant boot to recovery.
so i should remove the battery and try to flash it without battery plugged in?
because i tried to charge the phone overnight with no luck, havent tried removing the case yet because im not experienced to remove them, is there any alternative that i should try without touching the hardware stuff?

I would first try to flash just like it is now, without opening the back cover.
Opening the back panel is the last option I would consider, but only if everything else fails.
The thing with opening back cover is, that you will most likely damage you back panel, and you will have to order some new, fake raplecement + the phone won't be waterproof anymore.
And if you can get your phone into fastboot mode (and you've got unlocked bootloader) then just use "adb fastboot flash boot boot.img" command to flash some kernel with recovery.

Have you tryied to plug it in and then press power and volume up continiusly until you fell three vibrations? i think this is for reseting the phone if you continue to press until another vibration it will shut down and maybe then it will charge.

i tried the vol up + power only one time until it vibrates 3 times for the first time and its off, but when i plugged the charger its continues on bootloop cycles thus battery not filling up.
i guess im gonna try until another vibration and see what happen.
and thank you for the link, im gonna give it a try too later, im not home right now, cheers.

4 once the flashtool request to connect the phone connect the phone while keep on pressing the vol button
it should flash the ftf

It won't probably charge in fastboot/flashmode.
But it's very strange that the PC won't detect your phone when trying to enter flashmode.
Because, as I said earlier, I was able to get Z2 into flashmode without any power (battery taken out).
There should be some change in device manager when you connect the device.
Are you sure all the drivers are installed on your PC?
