[Q] [HELP] Sony Ericsson X8 Bootloop

Two week ago when i played radio from an application on my device while charging it, suddenly my device reboot and reboot again...
Then i was trying reset all data but the problem still exist...
So i followed some guide from this forum by rooting and flashing it using flashtool and using new firmware from provide link ( http://forum.xda-developers.com/showthread.php?p=19684920#post19684920 and http://www.mediafire.com/?d3pobqqc3py66#4c02265ox4l1r )
and the problem was still the same, reboot and reboot again, so i tried using PCC and SEUS but it didn't change anything..
Lately, when i charge my device, it didn't reboot, but when i didn't charge the phone, on some point my device reboot and reboot again and the battery went down to +/- 2-15%
What is really happen to my device ?? Is it battery problem or RAM problem ???
Sorry for my bad english, i am a newbie in this forum...
Thx for your help ..

Using PC Companion: Connect your phone to your PC and turn it on. Look around the update phone section of PC Companion for an option called "Repair your phone". Just follow the steps and your phone will be in working order pretty soon

i've tried it, but no luck....
or maybe i am right, the problem is the battery or the RAM...
cause it happen when i listening a web radio and charging my phone....
that time my battery is full but i forget to unplug it, and when it happen, the battery is enough hot....
or maybe my cache memory, that is used by a web radio application is full....
is any of that possible ??

When you close your phone the ram clears,which means there is no way you have this problem caused by ram..

Sony Ericsson X8 Bootloop
Hey I will tell you what to do.
First of all install Sony Ericsson Update Service or SEUS. Just Google it and you can find it easily!
Now connect your phone to your computer via USB cable.
Start SEUS.
Then follow the on-screen instructions.(You will be asked to select your phone model,update or repair your phone etc)But its easy!!!!!
Then leave the rest to SEUS.
It will first repair your phone,then download the stock rom and kernel and also the baseband and will automatically install them.
After that you will have your X8 on stock rom,it will be updated to the latest baseband and kernel.
Hope it works for you.

it happens to me also.but the only solution that i got to fix is reflashing a X8_E15i_2.1.1.A.0.6_Baseband_015.ftf. :laugh: i fix my bootloop

For my case, it will bootup with 1.6 stock rom, the baseband will be stated unknown, but it still can call and receive SMS...
Any rom that is above 2.1 won't be able to boot, that include stock 2.1 and any custom rom...
It only can be repaired by SE i think (or maybe JTAG )...
So in the end i gave up the phone and sold it at a cheap price to a friend and he took it to SE for repair, the phone comes back with stock 2.1 ROM
but the camera and vol button are not working, most probably damaged by the repair guy in SE...
Btw, any one knows what causes the baseband to gone like that?

How did you update, OTA or pushed via FlashTool?

flashtool

The only thing you can do in situations like this, as told in every such thread, is reflash with the flashtool.

Will FlashTool pick it up when connecting via Vol -Up? If so, try pushing the FTF again,even a different FTF?

i will try when i get home to see if it will pickup the flashtool.
it kinda sucks tho. why it did this ? i didnt even install anything in the stupid thing aside from few games. jesus.

What FTF did you use ? I would suggest using another just in case, you may / may not need to wipe data

the one from the main thread :/. " not the one with the typo "
i think its from singapore one ? because it had some stuff from that country.
i will go home in 1 hour or so and try to flash without wipe.
finger crossed :/

its not accepting the flashtool.
i turn the device off. i click on the back botton. but nothing.
the log says the file is connected in fast boot mode. but there is nothing . i still get the pop screen that shows the instructions how to plug your device.
any help

ok. by miracle i got it to work. but i am not sure what happened and why it did this.
all good i guess :/
also, i wonder if there is an official version of this. not bloated with weird stuff. like euro version or something.
also. one more question.
is there a root for this ?

Reinstall the software with sony update service is what you have to do
http://www.sonymobile.com/gb/tools/update-service/
glad to read that is fixed ..

I had this same issue yesterday. I installed the the update from the India c6602. Things were working fine the first day. I did a reset and then had the same issue as the OP had.
A re-flash with the flashtool didn't work the first time and the I tried the Sony companion fix option, and still had problems. Then I realized I had to install the drivers. Are you on windows 8? did you install the drivers that came with the flashtool? I did and then re-flashed, and now its fine again.

Most people seem to have flashed the Global FTF, you could reflash the old firmware, then when you plug into PC Companion it should flick up the update for you/your region.
I would just flash Global

Used PC companion to "repair" phone; things got only worse (no menu, black screen, still rebooting, ...)

No luck with sus. Tell me more about flashtool, I don't know a lot about it.

you need to download flashtool. its here in the xperia forum or googling "xperia flashtool" should give you what you need. then you need an ftf file of the firmware for your phone. again you should be able to find it here. go to c:/flashtool/drivers (on your pc) to install the adb drivers for your phone. use flashtool (from power off holding volume - anf plugging in to usb) to flash the ftf for your phone (67 fw preferred) and if you used the right ftf file for your phone (shoot download a few so you can play Round) it should reset like brand new.

Thanks. Is there any global stock rom to find it? Because I live in Slovenia (Europe) and I dont think that i'll find the rom for my country.
I have a question about stock roms: can i flash any stock rom that i find? There are also diffenrent model numbers (C6602, C6603, ...)?

I somehove succed to flash my phone and now i have one further problem. It says no sim card inserted, but sim card is placed in a slot. I have new sim card and it word on other devices. I allready tried different stock roms. My phone was bought in US, do you think that i must flash the US stock rom? Any other sugestions?

Firstly i want to note that my battery is certainly dead, and i can't charged it beacause of the restart/boot loop that i mentioned in my early posts...if yes, can you guys provide me with necesary tools, firmaware and stuff, because after all the attempts i tried, i'm afraid to do something else to the phone. I mean i was stupid in the first place to not ask how to do it properly, and i don't want to lose the phone...
And sorry if my English is rough

Hey guys, I don't know if this is out of topic but since this is for xperia z bricked, I'll show my problem.
So, I updated my xperia z for 3 times since I bought it, It came with Android 4.2.2 and the updates were all OTA.
Then, sudently It started to reboot itself and entering in bootloop.. Then, I tried to use flashtool but always gave me error about S1 flash, and then "Error: Flash Aborted"
So I tried to unlock my bootloader several times (Yes, several times, because it was always saying ok, but then it was showing "ROOTABLE") then, when I Finally got it unlocked, I couldn't flash anything because it was gaving me error saying that couldn't write boot.. Then, Tried Pc companion but again, failed, and my phone was stuck in "Update failed (...)"
Then finally, I flashed advanced kernel by DoomLord and entered in CWM, but when I tried to wipe factory reset, It was saying that couldn't mount data.. Then, I have formated the Data and Media (SD Card) And then, I was able to do factory reset, but, then, I went to advance and did reboot recovery.. My phone turned off, but never came on... I arrived at home and connect ti to wall charger, but no sign of life, nothing, not even red led or anytihng.. NOTHING!! Don't know what happened.. I really need help on this man, please :c

Xperia Z restarts

Hi my friends.
Today was very bad day for me. First my bird died, then my phone stops working and i stuck in elevator. I need your help. Afternoon i want to call my buddy for lunch. Everything starts after lockscreen. When i call him phone wont connect to operator then it says no connection and stuck at dialer. I push power button to get lockscreen and it frozen for while then it locks and i opened lockscreen. When i saw launcher phone resets and every time it resets at SONY logo. I flashed my device 3 times or more. I used .233 . 230 and 4.3 . Every time battery shows wrong percentage. Phone opens when i plugged to charge. But if it has sim card it resets. When i disconnect from charger it resets. I try to open USB DEBUGING for install recovery to reset battery info but when i check USB debuging it resets again. You guys have any idea for that problem.

Did you try clean installation?

did you put the phone in flashmode?

Try pushing your simcard back in place, sometimes it'll get out of place, and then you're phone won't connect to network and reboot every time it thinks simcard is removed

Oh, and battery will show right percentage again if you fully charge it

Looks like the is some issue with Sim assembly or can be a software/hardware issue.
As all methods have not worked take the phone to a service center and get it diagnosed

ive got the reboot problem too,
try to use philz touch, go to mount and storage, mount system, factory reset,
go back to mount, mount system, flash rom
keep stamina mode off, so far that has kept my rom stable ( tried to turn stamina mode on and caused a reboot after an hour or so)
im not sure if this a final solution, but its what i am trying

Yesterday i got my device from service. They change full body. I didnt understand what problem couses it. Now everything works fine.
