[How-to] Repair Damaged Bootloader + Trim Area [Red Led][Unknown Device] - Xperia Arc General

Hello again
Sometimes we can brick our devices by a bad unlock, flashing process, or simply bad luck.
The phone doesn't turn on and there is a Red Led Of Death when pressing power button. Even with a GREEN led when we plug the phone with back key pressed the computer detect the phone as "unknown device" so there is no chance to get fixed by Flashtool or SEUS/PC Companion.
Well this problem normally means that the bootloader is broken or damaged. So, in order to fix it we need to write a new SEMCboot and after this we were able to flash a full and fresh firmware with flashtool and unbrick our Xperia.
This process like unlocking process requires SETool dongle/box and a paperclip to make a testpoint to put the phone in flash mode and be able to write the SEMCBoot.
I can help to anyone with a bricked Xperia Arc/Play/Neo/Pro just make send me a PM.
Like unlocking process you will need this 3 programs:
SETool software for unlocking
USB Over network client for remote dongle
Teamviewer client for remote support and guide
THIS PROCESS IS FREE
anyway if you want me to buy a Dr. Pepper just

Sometimes even after fix the bootloader the phone doesn't want to boot. In most cases this is by a damaged TRIM AREA (TA).
The trim area is a part of softwere stored in eeprom so it can be read and write with the proper software like SETool.
Read and Write trim area is very easy but you should know that some sectors of the TA are unique for you phone, lets call it Security Units.
The process for repair trim area is indeed very easy.
For sure we need Testpoint like in unlocking or bootloader repair process.
1. Backup Security Units with this script:
Code:
taread:00020851
taread:000207D3
taread:000207Da
2. Write a Working TA backup from another phone (same model)
3. Restore Security Units.
Thats all, now your phone should boot well but is 90% possible that you dont get Signal so for fix that we need to unlocking.
If this last thing is needed you can refer to this thread:

Trim area repair process is now tested and working for NEO PLAY and ARC

So it's work for 0% issues?

No bro this is for bootloader and trim area repair.
0% issue is about a charging sensor so it can be fixed with this

So is this a yes or no? Does the repair of the Trim Area get rid of the 0% battery issue?
What state does this leave the phone in? Will future OTA's screw the phone up again or is it back to factory build?

Trim Area repair does not fix the 0% battery issue. As for your other questions, I have no idea.

//edit:
whole process took about 5 minutes, didn't need to flash new software, just write new semcboot.
thanks a lot, phone is working again!
i can totally recommend this for people having a broken bootloader

Start calm.
All you need is a cool mind now.
Search for the USB JIGGS available on xda and see if someone from your area has it. You can then take help from that person. If not then just go to service center, tell them that it stuck like this while doing software update and act like you no nothing about rooting our flashing. That will do.

Yes, offcouse.
Just let them be unaware of you knowing about root/cwm etc. just act dumb. If they get to know your warranty is already void, they will charge you money for repairing it.
Follow what bruce says..
Tell them u got an update in kies nd this happened
** rooting is new for me,
nd i am a noob to root....**
They said Board is damaged

The last 'n' only hope left is this:-
Install ur phone specific driver on pc.
1. Take out battery, sim & sd card.
2. Open odin.exe on pc.
3. After this, connect the phone via USB cable to PC(yes! without battery,sim & sd card)
4. Press the download mode combo keys.
5. While keep pressing all those keys, insert the battery now.
6. Now, odin should detect ur phone so that u may get it updated with stock firmware.
And if this also doesn't work, then bro u might have lost it at all

bud same thing happened to me. and unfortunatly there is no fix for this. everytime i turned my phone on i got the little android guy then it would stay on lg screen with blue and green LED. try download mode it goesto the first screen of little blue dots.
since warrenty should not be able to tell anything about root or etc. i sent it in. in the mean time i called my carrier company and they sent me out a new phone for 35$. but i have to send old one back wether it ges fixed or not.
sorry bud but there is no way back from that. even tho your computer gives it a port its not fully booting so you cant flash anything..... here is one last thing you can try................ this could be your only hope.......it didnt help me but it might work for you...

thank you so much sir for replying, what is really wierd is that when i connect it to my pc, kingo root detects it, and gives me the option to root, then the rootin process stops at fetching scripts.
I cannot read.

Exhaust all options before giving it up for repair or warrenty exchange good luck and i hope you are more secessful then i was. Altho rogers did send me out a new phone good luck
thank you guys , my phone when on lg logo, and connected to pc, i can see it in device manager under modem as LGE android net usb modem,
and under ports as LGE android serial port com 8, any chance or sign of live to my phone, as mentionned before, there is no waranty services in our country.

Completely dead P9 lite

So it looks like this phone is not completely unbrickable. I've seem to brick mine pretty bad.
The phone doesn't turn on at all. No vibration or other kind of feedback.
Doesn't appear on the computer either.
So my question is: is there any emergency download mode like in qualcomm based phones?

It seems completely dead. Probably only with test point. Warranty most likely will refuse it since it is boot loader unlocked.

Yes Warranty falls if the bootloader unlocked. Test Point could help.
Well warranty will most likely only complain if it was bricked by the user and software modification.
If your phone broke because of an hardware issue, you have a chance that warranty still repairs it for free.

Well since it broke after I flashed b160 firmware I am most likely SOL. Since I had twrp flashed they will find out that it was modified..
My advice is not to mess with fastboot mode. Flash twrp and be careful with what you flash.
Did you tried to flash original firmware with the three buttons?

Yup. It's completely dead. No fastboot mode, no recovery or erecovery. It simply does not turn on (or enumerate in a computer either).
If you could boot into recovery,the rest would be simple....download the stock firmware, unzip it and push the file to your phone,then install

Have you tried to enter fastboot or recovery solely using the button combos? or did you try using adb as well? It's possible your battery deep-discharged, or your power adapter/connectors are faulty.

Yes I cant enter anything in fact. There was a suggestion to connect the phone without battery to the computer but it implies opening up the phone and even if it did something I don't have the tools to flash it. (dc-phoenix only seems to work with phones with fastboot working)
As far as I know the symptoms that my phone is experiencing are due to the fastboot partition being messed up.
As far I was able to research there is another boot loader before the fastboot one. But the phone doesn't respond at all, it is dead. I will ask around in phone repair shops if they can reflash the phone.

Before you do anything rash, have you considered getting a usb jig? Simply put the stock firmware on the jig then plug it into the usb port on your phone. It will automatically put your phone into download mode and install the firmware. Here's the link to make your own usb jig http://forum.xda-developers.com/galaxy-s2/help/guide-how-to-make-usb-jig-reset-binary-t1604707. Hopefully this helps!!!

That is for samsung phones. I gave on trying to fix the phone. Next week I'm going to send it to a phone repair shop and see what they can do.
Edit: The phone repair guy says that the only way it can be repaired is by replacing the emmc or replacing the motherboard. So for now the phone will sit in the drawer until I manage to get a new board.
Hello
I had the same problem with my honor 7, the only solution is to replace the motherboard :/
If the phone is completely dead, warranty will accept it just because they will change your motherboard if they can't turn it on. I had the same problem last week, probably an hardware fail, I gave it to them saying that the phone simply turned off and they changed the whole motherboard (bootloader unlocked, twrp and root).
Well I tried sending it to the repair center. Two days later they replaced the whole phone, they said that there was an issue with the power ic.
B160 works for me.. hmm.... using it for like a [email protected]@
might be your hardware that cause the problem and not the firmware?

I'm starting to think so, I've flashed the replacement and it didn't brick. May or may not be related to the headers, but I don't want to be creative right now since I need the phone lol.

Qualcomm hs-usb qdloader 9008 nexus 6P (HELP!)

Hi there, I've been browsing through the threads related to unbricking of the Nexus 6P stuck in qualcomm hs-usb qdloader 9008 mode, really desperate to get my device working again if even possible however I've tried for about four days now different ways and files and I've had no luck.
My bootloader is locked and no ADB etc managed to get my device showing as the 9008 port so I think it's stuck in EDL.
Following guides, this is the furthest I've yet to get (In screenshot)

Use a hairdryer to warm up the back of the phone.
Are you pulling my leg? Warm it up then reflash?
nah im not trying to make you destroy your phone, being rather serious with this method. i use it on a daily basis to solve phones that fail during restoring factory images. i wouldn't know how long to give it with a hair dryer as i have access to a heat gun/heat mats .
just think of it as a cheap mans re balling method

thank you so much that worked, it has said flash successful, first time I got a google logo but now nothing, what would be my next step please?
if the bootloader is unlocked then you can directly flash the firmware. but if its not google "nexus ota" and then on your phone jump into the recovery and check the firmware model number and download the same ota and adb sideload it.
im not 100% sure on the next step as I've never had a nexus 6p with a dead bootloader. but thats what id do.
---------- Post added at 04:50 PM ---------- Previous post was at 04:49 PM ----------
but from my personal experience with having to heat a phone up to restore factory images, it kinda means the phone is nearing the end of its life and id start thinking about buying your next phone before it sh*ts the bed.

Thank you for the reply and continuing to help, after seeing the google logo just once I'm getting nothing again - I'm even more determined now though as It's been dead for 2 months so this is the furthest I've gotten - the application of heat is what did it for me and fixed the error I was getting, can't get into recovery now though holding power + down etc

yeah can you access the bootloader at all ? does it say that the bootloader is locked ? from trying to restore LG's it sometimes has to be re heated a few times, but yeah if you need to re heat it to get further into the phone then its pretty much a lost cause. the only reason i do it is to remove the data so we can resell the device.

I believe so, I can just about get into the bootloader at the best of times and when I do I can select options but once proceeding to start said mode phone freezes so can't get into recovery mode :/
Thank you for your continuous help, only way i can get it into bootloader is by heating it up so does that mean for the device to ever work It'll need heat every time? looking like a spares and repairs listing on ebay

Hello....
How did you manage to get in to EDL mode..? I'm really curious. With stock bootloader? Since you can't access recovery
Also what is exactly displayed in Windows device manager?
You are using an outdated QFil version... It is from 2014 àr 2015.
Do a google search with: QPST_2.7.453.0 . This version seem to be from 2016.
Use the first link from the result. I analysed the files with virustotal, those seem clean or malware...
Also when plugging your usb cord to your PC, does your phone vibrate? Or does the LED blink in red?
You may have to press power button when plugging the usb cord or press power button for a certain amount of time before you plug the usb cord. I'm not completly sure, but your phone may not be in the "proper" EDL state to accept the QFil flash.
Good luck... :good:
Is it possible to send me the guide you used? Thanks.

Hey there sorry for slow replies, will be back on my desktop in an hour I'll send you links for what I followed and such, I think the only reason my device was in EDL mode was due to a hardware fault? As my device is faulty indefinitely as I had to use a hairdryer to warm it up while flashing this then allowed it to enter firehose state which a lot of people seem to error with - after all my attempts and research I'm to velieve there's a fault with the phone itself the only way I could get it to even power up was applying heat to it after removing the back panel
As blackcell said deballing or something? Worked a treat!
Furthest I've managed to get now is into my boot loader however everything is locked - when I press enter recovery my handset just freezes ?

Light usually a red LED blink while in proper EDL state as far as I know. Could be something else on the N6P. Well, it looks like you are SOL. Sorry, I don't know what else to say, since you exhausted all possibilities...
Good luck...

[F32xx][F31xx][Guide] How to unbrick dead Xperia XA and Ultra

Hi all,
Today I will explain you how to unbrick your dead phone, now that I have a XA Ultra for dev and test I tried to kill it (yes I'm crazy).
until now I didn't searched all ways because my XA was my daily phone and when I asked the community to send or sell me a dead phone, no answers
I tried many ways to brick and unbrick the phone, tried to brick it by not using FSC file, using an old Falshtool, flashing boot.img from an other device (Xperia X and Z5 ) and I always recovered it. In my last try the phone was totally dead, no red light and not detected by my computer but all ended fine :good: I will upload a video soon.
On Mediatek devices, if the preloader is not corrupted you can always recover it. If it doesn't work for you maybe you can use some "special" boxes to connect on the UART serial port and flash the preloader but I didn't find the correct pinout on it and no proofs what will work on XA and Ultra.
Other thing, if someone claim that he found an other way and need your phone (and money), don't trust it until you have some real proofs (some users know what I mean), it's probably a scam to steal your phone.
By following this guide you will void the warranty so do it only if you can't send it to Sony!!
## What we need ?
- Some tools to open the device (a plastic card can be enough)
- The last version of Flashtool
- Flashmode drivers installed (you can install them from Flashtool)
- A firmware downloaded from Xperifirm (inclued in Flashtool)
- One set of sticker glue tape for the backplate like this one:

## Step by step guide
1. Follow this video to remove the backplate (thanks to the author): https://www.youtube.com/watch?v=2O5dAljOpR4
2. Unplug the battery connector, pull it from the upper side very slowly or you can damage it.
3. Open Flashtool and load the firmware (remove all TA related partitions), click "flash" and wait until you see the popup to plug the phone.
4. Hold "vol-" and plug the phone, you will see the red light 1 seconde and the green light just after.
5. Release "vol-" button and wait until the end of the flash process.
6. Unplug the phone, plug the battery connector and power on the phone.
7. If it's ok the phone will start and you can put the backplate again (clean the old glue and put the new sticker)
## How to avoid brick
First of all you must understand that flashing something on our devices is always dangerous, official or unofficial things.
Generally our devices goes wrong after updating the firmware, to reduce the risk you have to follow some simple things:
- Don't unlock the bootloader and use OEM tools.
- Always download files from trusted sources.
- When you use Flashtool, always use the last version, download the firmware from the inclued Xperifirm and always use FSC file when asked.
If it worked for you, don't forget to feedback, hit the thank button and why not offer me a coffee

You followed my guide? Have you the green led?
what should i do if i don't get the green led and can't enter flash mode
It stays at the red light..
what else can i do?
If it doesn't work for you I don't know what you can do. Maybe if one day it doesn't work for me too I will try some more experimental things or if I can have a device with the same problem in my hands.
Welcome my dear friend! My phone is also lit red led. How to reflash?
Unfortunately at this time their no way to reflash your phone if you have that red light flash only
If don't have flash mode or fastboot use able their is not a way to recover.

my xa ultra dual wont response the touchscreen
hi all I desperately need advice for my unresponse or maybe likely death xperia xa ultradual.
I have some lagging issues at first then I reset to factory, then comes normal then a week later become lagging again,and finally stuck in the welcome screen after xperia logo and I the touchscreen becomes totally unresponsive ,the detailed are in this link youtu.be/_ELKIpn7QG8
I wonder should I change the LCD TOUCHSCREEN or is it just some corrupt files that caused this problem, because I experience someflickering isssues in the screen. FYI I still learning howto use a flashtool cause I am afraid that it can brick myphone.
very much appreciated,warms regards from Indonesia
my BL still locked but I dunno, somehow i feel safe & happy to found this thread
keep the good job mate!
sony- android- xperia- off
good day! i hope im on the correct thread. i am having this issue on my xperia xa ultra dual.
everytime i turn the device on, it displays the sony logo, then the android logo, the xperia logo, then it turns off. i cant seem to get past through this regardless if i'll press the volume- and power or the volume+ and power. im almost certain that this can be fixed by doing something on the flashtool. i guess i just dont know how to do it. a step-by-step tutorial is greatly appreciated.
If you have why not share it in xda? Probably you are a scammer and request money in order to unbrick phone... Seen so many like you

I totally agree with you, and now you can see fake users who post fake feedbacks but until now we have absolutely no proof about this miracle
Its like videos on youtube with title saying 2017 paypal free money hack, which directs you to a survey site and wants you to pay money in order to download a 'paid virus' even though it says free you still pay for a virus. They are too funny man

F3213 DEAD
SOMC MTK6755 Virtual Serial PORT Driver shown in device manager .
hey there my xa ultra phone is not even starting like its fully dead what is the solution
I know I'm late but, Those who are having problems with green light not showing up:
1. Hold the Volume Down button
2. Connect USB
3. Keep holding the button for 30 seconds atleast.
When bricked, device doesn't show green light readily. It takes atleast 30 seconds.
Thank you
You're the BOSS! You've saved my Mini ST15i. Thank you! :highfive:
