[Sony Xperia XA Questions & Answers] Vector Edge:
I have seen here on XDA, in the [Guide] Recover 2012 Xperias and newer, that guys are suggesting two totally different (at the first sight) options in order to unbrick a Xperia.

1. Drain battery completely.

2. Plug the phone in the wall charger and wait for days.

As far as I understand, plugging in a phone with a bad kernel will not charge the battery, the battery will drain, after that it will start to recharge. But this works in case when you don't get a red light when plugging in the phone. In my case I get the red led right away, once I plug it in USB or charger, but nothing more than that, no bootloops which would drain my battery, no charging battery icon, no black screen on, nothing... :(
[Sony Xperia XA Questions & Answers] rrvuhpg:
I can confirm, if phone have only red led and you can listen plug/unplug sound when the phone is connected on the PC, the phone is in bootloop on kernel/ramdisk init, you have same result as flashing a bad boot.img

If you are lucky the preloader is not corrupted.

Try to plug phone to PC, put Flashtool in "waiting for device in flashmode" state, hold vol- until the phone "reboot" (next time you listen the plug sound). The flashing process may start.

On the very begin of the init, the phone will start with flashmode mode for 2sec, if a command is send at this moment, it will stay in that mode. It's like an emergency access, thank you MTK :D

XA and Ultra are not Qualcomm, if you want guides, tuto, dev tools, you have to think MTK. Look at Elephone M3 or P9000 to understand ;)
[Sony Xperia XA Questions & Answers] Vector Edge:
I understand that MTK is not Qualcomm, and there is a different approach when in comes to unbricking the phone. Could you, PLEASE, suggest me a source where I could find different methods to enter Flashmode on a MTK? I have had the rubber band on the volume down which was kept pressed for a whole night, with the Flashtool asking to connect the device in Flashmode, but nothing good happened. And the phone was connecting and disconnecting continuously (kind of bootloop, but without any obvious sign on the phone). Bootloop continues only if I have the rubber band on the volume down or on the power button. Otherwise, without a rubber band pressing the buttons, the phone just disconnects (even if it stays connected by USB).

I'm really lost: Should I keep charging the battery until it gives me any sign of life? Or should I leave it alone until it fully discharges??
[Sony Xperia XA Questions & Answers] LuiGi_MM:
Have you tried to repair it through Xperia Companion on PC?
[Sony Xperia XA Questions & Answers] rrvuhpg:
If you tried all over a night your battery is probably full now.

Try an other way: unplug, hold vol+ vol- and power for 8-10sec (force shutdown), release all, hold vol- again and plug.

You can find guides all over the web, generally for other phones you can remove the battery...

NEVER USE MTK SP FLASHTOOL

Your phone can really have a hardware problem and need to be replaced/repaired, do this if you can. That's very strange if your bootloader is locked and you have this problem.
[Sony Xperia XA Questions & Answers] Vector Edge:
I can not use the Xperia Companion method as I can not get into the Flashmode
[Sony Xperia XA Questions & Answers] Vector Edge:
- Vol+ and Vol - did not force the shutdown.

- I literally read already thousands of post on xda, and I can not find what it takes to quit this bootloop

- Why should I never use MTK SP SLASHTOOL? Isn't it specialised for MediaTek ?
[Sony Xperia XA Questions & Answers] aidy.lucas:
Something must of been done differently, I know if it asks for a fsc script you should choose yes(pretty sure this was part of the reason m5+c5 were hardbricking), I'm also pretty sure that only Sony service centre can ressurect it if it's not responding to anything. Best advice would be to take it to them.
[Sony Xperia XA Questions & Answers] Vector Edge:
When I installed the previous version of the firmware xxx.2.93 (just one hour before the fatal flash, when I wanted to flash the vershion xxx.3.74) on the same phone, on the same PC and with the same Flashtool, then I choose NO for the FSC file as well, and everything went good, and the phone booted afterwords with no problem!
[Sony Xperia XA Questions & Answers] rrvuhpg:
It worked many times for me (builded many wrong boots and kernels) and always resurrected from same phone state as you and I have the F3112.

SP Flash Tool will not work and can corrupt your preloader.
[Sony Xperia XA Questions & Answers] Vector Edge:
Ok, rrvuhpg. Let's start over again.

I was keeping pushed the Vol+, Vol- and Power button for about 20 seconds, and nothing happened. No reaction on the phone. And once it is not connected to the PC, I can not understand if the phone changes its state or not. For any combination I tried with the buttons and plug/unplug usb, I can never get a vibration, a screen on/of, or any reaction. The only reaction I have is when I keep ONLY the power button pressed for 15 seconds, then I get one short PURPLE LED flick, but no vibration or anything. Even after this, when I try to connect to the Flashmode (Vol- and Plug), it is still determined by the Flashtool as a Device with USB Debugging off...

What exactly are you doing in order to get a full shut down, in order to enter the flashmode afterwords? How do you know that your phone shutted down?

Am I missing something? Please HELP me. Any suggestion may help and is highly appreciated.

Edit: I just tried to keep all 3 buttons pressed for a longer time, while Unplugged! I still get that purple led flick after 15 seconds, and nothing more. Once I replug with the Vol- pressed, it is immediately recognised by Flashtool as a device with debugging off :/

Edit 2: If i keep the Power button pressed all the time during it's plugged in, it keep connecting and disconnecting, and reconnecting immediately each 5 sec (I can hear the windows sound, and I can see in the log in Flashtool). To mention, that when I have the rubber band over Vol- button, I keeps disconnectin once in 15-20 seconds (much more rare), and reconnects after about 10 sec.
[Sony Xperia XA Questions & Answers] rrvuhpg:
Your steps are good, just try to reduce hold time to 8-10sec, if too long the phone reboot. You can't see anything because the phone is stuck before the screen init. First time it happend to me I tried many times to find the good timing. I know your drivers are probably good but can you confirm they are coming from same links as in my root guide thread, and you installed/updated them manually ? On others MTK devices you need drivers called Vcom to recover from hard brick, you can't use generic drivers that's why I ask you.

As said before that's very strange to have your problem on a locked bootloader, probably your phone need to be replaced in warranty.

If you want I can make a small video to show you but not before next week.

Edit: look this guide, it describes how to recover MTK devices from hard brick

http://phonesinnigeria.com/unbrick-hard-bricked-dead-mtk-android-device/

Don't try, it's just for you to understand the similar way for XA

SP Flashtool = Flashtool

Vcom driver = XA official driver

Scatter file = FSC file ?? (not sure but you must act like correct)
[Sony Xperia XA Questions & Answers] Vector Edge:
I have tried many times, starting to keep pressed Vol Up + Vol Down + Power Buttons in many different combinations, starting from 1 sec to 20 sec. I have also tried only Vol Down + Power buttons. Nothing. Every time I am connecting my phone to the PC, I get the same message that the device is connected with USB Debugging Off...

Regarding drivers, besides the fact that I had all the drivers installed OK before my last fatal fw flash, I also installed the Vcom driver afterward. Now, in this state of the phone, in Device Manager it is identified as MediaTek USB DA Vcom Port. I was also trying to install the driver from your Thread (about ROOTing), but it doesn't work, as the Windows says it is not a compatible driver. Probably because I have Windows 10 x64. And yes, I deactivated the signature check before trying to install the driver.

Regarding the video you are offering to do for me, thank you very much, I appreciate your intention, but the next week is too far away. If I can not recover my device today or tomorrow, then I will return it.

What I am trying to do now is to completely drain the battery of the phone. I thought that once it is in a sort of loop and I can not turn it off, then I will just kill the battery until it will switch off itself. When I keep it plugged in the PC usb, I can hear the connected/disconnected device in Windows, as well as it is shown in the Flashtool window. I also mentioned that if I keep the power button pressed, the loop happens much more often, which consequently would kill the battery faster. So I just put a rubber band around the phone which keeps the power button always pressed. I do that since yesterday. What I mentioned is that yesterday after 15 sec of keeping the power button pressed, I got a Purple led flick. Today, I am getting already a Red led flick, with much less intensity. I hope soon the battery will die and I will be able to put it in the flash mode. I don't know what else I can try...

EDIT: Did you upgrade to the last firmware version xxx.3.74? If yes, did you use Flashtool? Did you download it from Xperifirm??? What Customization did you use? Customized FR? What exactly did you check to WIPE and to EXCLUDE? Did you accrept or refuse the FSC file?

The point is that exactly this version of firmware ...3.74) killed my phone. I used the	CIS RU UA KZ BY Customization.

Thanks for your cooperation!!!
[Sony Xperia XA Questions & Answers] rrvuhpg:
I don't have other idea to try for now :(

I never tried with Mediatek Vcom drivers on the XA, interesting to see you don't have error with them. we can imagine firmware 33.2.x.3.74 can kill the phone and that's why Sony stopped to deploy it. :confused:

I'm on 33.2.B.2.93 CE1, was customized FR out of the box.

To update my phone I use Flashtool and Xperifirm, use FSC file, wipe cache/dalvik, exclude boot and fotakernel (nothing to exclude for locked bootloaders)
[Sony Xperia XA Questions & Answers] Vector Edge:
Please, tell me how is the battery life in your XA with 2.93? XA is famous with its poor battery life on all the forums...

Wow, that's an interesting news! I didn't know SONY stopped delivering the new 3.74 XA Firmware. That means they recognize the problem. Also, there are a lot of complains on the official Xperia forum about SD card continuously ejecting in the same FW.

Regarding Vcom driver, I installed them manually in my desperate attempts to recover my XA. To mention, that in this brick state, my device was recognised as some kind of generic USB Device. Before the brick, the device had all the necessary drivers installed through Xperia Companion and Flashtool Drivers.
[Sony Xperia XA Questions & Answers] rrvuhpg:
I have 2.93 firmware with 2.95 kernel (not released by Sony) and I have 4h30-5h screen on, not bad if you look other equal devices. In idle the battery life is more than a day without problem, no stamina, only doze mode. (With ForceDoze app tweaks)

For the firmware it's not a news, if you look here

https://xpericheck.com

The 3.74 firmware is not deployed as fast as usually, or I missed the official news.

I will try to install Vcom drivers and flash my phone to see if it can work for you.

I'm not sure if Flashtool provide specific drivers for XA or if they are generic. I recommend to use drivers from Sony Dev.
[Sony Xperia XA Questions & Answers] rrvuhpg:
Screenshot :)

My brightness is at 50%
[Sony Xperia XA Questions & Answers] Vector Edge:
That's the exact link where I always check for new firmwares. And the 3.74 firmwares (all customizations) are still there. Am I misunderstanding something? Or, what do you mean they are not deployed as fast as usually?

Don't flash your device and erase everything just for a driver. It's not worth it. Thow, thank you for your intention and for the screenshot. :good:
[Sony Xperia XA Questions & Answers] rrvuhpg:
No problem I'm happy to help you, I corrected my link to Xpericheck you have to see all F311xx, I think some customizations are missing I'm on CE1 and nothing. That strange, a "massive" release in 3 days and nothing after, usually we have some releases more often and where is the firmware 33.2.A/B.2.95? But it's not official, just my feedback.
[Sony Xperia XA Questions & Answers] wrundawan:
Scatter file is not equal to FSC file.

I tried to change fsc file to txt format to but it wont detect it.

[Sony Xperia XA Questions & Answers] wrundawan:
Yes I had send it to Sony and those guys said for motherboard replacement which is half of the price of this device. So I avoided and waiting for the solution to fix this issue.

I hope scatter file based firmware may fix this problem. Just waiting if someone can help me to get scatter file based firmware for flashing with SP Flash Tool or Crack version of miracle box.

Flashtool will brick your device

Think twice before flashing your device via flashtool by androxyde it wll brick your device
[Sony Xperia XA Questions & Answers] aidy.lucas:
I've flashed my xa numerous times with flashtool no problem at all works like a charm most recently I flashed it yesterday, you just need to know what you are doing. The attached screenshot is from when I flashed it a while ago. Use flashtool in simple mode only(it automatically starts in this mode), I always wipe the device clean (I. E. User data), and as long as you select the same as I did before flashing it should be fine only part of the ftf I leave out is the simlock.Ta part all other parts with. Ta in I leave in, removing them yourself and changing from simple mode is what causes the bootloop+hardbrick problems along with people not really knowing what they are doing most guides on the net are outdated and for older jb+kk+lpop
[Sony Xperia XA Questions & Answers] wrundawan:
Mine device is F1116. I flashed latest firmware via flashtool and I got flashed successfully message but when I disconnected device it's not booting at all. Again I tired to connect it in flashmode but now it won't enter in any mode just gives red LED,, no vibration on holding power +volume up botton.

Now for me no option just have to go for motherboard replacement.
[Sony Xperia XA Questions & Answers] wrundawan:
Any one give me screenshots of device manager when sony xperia is connected.

Help me guys,,I am looking for screenshots of device manager when sony xperia xa is connected to PC in Flashmode, Fastboot mode and in normal mode.
[Sony Xperia XA Questions & Answers] Lexheader:
So... there's no solution for this brick? the only way to revive the phone is to deliver to Sony? :(
[Sony Xperia XA Questions & Answers] derpydm:
Nope.

In fact, flashtool has unbricked my phone everytime I screwed something up.

Not a dev myself, but I've flashed an Xperia L, an Xperia E3 and my current XA. You must have flashed wrongly for it to hardbrick.

As long as you don't corrupt the preloader it can be saved (it's an MTK device after all)

I'll SS device manager when I get home.

To the post above me, the answer is probably yes.

with this method you do lose the unlocked bootloader, don't you?

I tried it on my friend's axon 7 the other day and he was able to get the update but the bootloader was locked again. For him it doesn't matter as he uses stock and no apps that require root.
[ZTE Axon 7 Guides, News, & Discussion] DrakenFX:
as far my understanding if you are already BOOTLOADER UNLOCK you still be in the same state (Unlock).

[ZTE Axon 7 Guides, News, & Discussion] xtermmin:
I'm guessing you went through the official ZTE bootloader unlock process, ie filled out the form on their site. When you do that, your device IMEI is placed on a list that will no longer receive regular OTA updates, and will only get B20_Boot.

Try putting the B27 OTA update ZIP on an microSD card, rename to update.zip, make sure that OEM Unlocking is enabled in your developer options, boot into stock recovery, and apply update from microSD card.
