[Q] Problems by unlocking and locking bootloader ? - Sony Xperia L

Greetings fellow , several weeks ago I decided to unlock the bootloader to test different ROM , I tried many and I stay with cyanogenmod . Given that came to my C2104 official update from sony to 15.3.a.1.17 , I decided to lock my bootloader . I tried a few hours the new official firmware and I was so disappointed by his failures I decided to return to the CyanogenMod ROM . I went to unlock my bootloader but since every ROM I try very unstable , contacts are lost , almost all applications I open lock and close, I have signal problems wifi and 3G (perform all wipes needed for each installation used ) . because I 'm desperate .. block before returning to my bootloader any ROM that proved it worked perfect, but now after the new block and subsequent release any ROM is stable. To top it all went back to the stock ROM 15.3.a.1.14 that has been the stock that has worked best for me and I will ... Did fatal ruin my xperia for having repeatedly locked and unlocked bootloader ? sorry my English

i dont get the question u r asking..hehe but i think u r asking if relocking and unlocking bootloader will damage or ruin the phone, am i right? we'll to solve ur problem there are instances that it will brick ur phone and there are instance also that it will succesfully loack, i think it will be differ on the build of the board..just an advice, if u wanted to try other ROMs better not to relock ur bootloader so it wont mess up ur phone..stay unlock

Thanks for replying. I know the risks of opening the bootloader. In short I mean, excluding damage, the phone may become unstable by opening and closing the bootloader

Please create an backup of your Rom using CWM and then you can try to update/flash your phone.. If your phone is locked again, put your backup back in and search for an patch for multilanguage with arabic support..

NO, the phone will NEVER be locked again
SIM LOCK is more like a hardware based security, not software.
you can flash stock safe

after you unlock the sim, you have to flash custom recovery and then root
then you can flash custom rom through recovery
BTW, its possible the phone can be lock again only if he unlocked the sim via root exploit
if he used an IMEI calculator, yes it is ok

at this point, your phone is not unlocked via root exploit
so you can do whatever you want, it will not lock
and the unlock being part of hardware, it will never lock back unless you want it to happen

he flashed stock rom as the method of calculating the unlock code based on imei is valid for this phone on 2,3,6
he could do this on kk risking to not work and losing the money
maybe he thinks the code resets the bootloader which happens on devices such as htc
but i have here a clear example:
if you use the yellow triangle away app from chainfire and you flash another rom, does the yellow triangle appears again?
i guess you know what is triangle away, search it on google if you dont
and the triangle thing is a hardware code, so is the sim lock
Hope i helped you!

abnormal phone behaviour with 5.0.2 need help

first of all, i have searched a lot about the issue i am having, i have not found a single one as mine.
XT1033 with locked bootloader
It started with 5.0.2 ota update, the update file was downloaded and flashing was smoothly done, after the final restart it stuck in a boot loop (on the moto logo white coloured). i straight away went to service center and they told me that my motherboard was the issue, needs to be changed for almost the cost of the phone itself.
then i thought of trying somethings from here (xda), found [5.0.2][Restore to Stock][XT1033] Asia Retail [Dual Sim][4.4.2/4.4.2][LockBootloader] i tried flashing stock firmware from this thread not flashing the "mfastboot.exe oem lock begin" and "mfastboot.exe oem lock" part. And the phone started!!!! i was laughing about the motherboard thing
Used it for about 15 days with no bug, no issues, no random reboots, the again one day it simply went into bootloop again, i was sure that there was a hardware issue, but then again i went through the same procedure and it was again working, this same process has happened for about 4-5 times on the last month.
i would like to know:
1. Is it a hardware issue? (service center people will surely make me buy a new motherboard)
2. Is it some kind of issue with the lollipop, downgrading to kitkat will help?
3. any permanent solution (or will i have to format the phone every 10 days?)
any help is very much appreciated.

Replacing the motherboard is a very bad idea as you can buy a new phone from that money
You can try unlocking the bootloader and flashing a custom ROM
PS- After unlocking BL You can take a backup is your data partition with a custom recovery and then no worries of data loss
So this is not a hardware issue??

I can't tell you that now because it may be after all a hardware issue
Now
Is your phone in warranty?
Do you have any problem in unlocking the bootloader?

no, the phone is not in warranty.
And about unlocking the boot loader, one option for me was to get a new moto g 2014 with exchange offer on flipkart (i am from india and flipkart is reducing about Rs 3000 for this phone). So i am not sure that if i unlock the boot loader will they accept it??
is there a way to relock it and make it stock?

Yes you can lock the bootloader again but that's I think not gonna help because when you unlock your device you need to get the unlock code from Motorola only, so they after all know that you unlocked it once
And buying a second gen moto g is not a good deal at current time as the internals are almost same on both devices and besides you are getting only Rs 3000 off that's not a big amount on money considering that you may still be able to save your device

thanks for the suggestion.
as soon as i get home, i will look into unlocking bootloader and installing some custom rom, can you recommend any particular rom that you are using, need it as a daily driver (stable one) .

And please think before talking any step
I said "you may be able to save your device" and not "you will surely be able to save your device"
Don't blame me if custom ROMs are not able to solve your problem
These things don't always have a desired output
Now if you are ready for some customs things my suggestions to you
* Use either philz touch latest or TWRP from xda ( and not from TWRP's official site)
* For ROMs , if you still want to stick with Motorola's stock ROM you can try custom recovery flashable zip made by @lost101
He made both normal variants and optimised ones
*Or if you wanna use custom ROMs try CM 12.1 latest nightly
*Read properly how to flash everything
*If while flashing anything you see any error in logs report back ( it may be able to tell if there's a hardware fault)

will flashing stock rom again in unlocked phone lock the phone ?

..I was already told by a friend here that if I again flash a stock rom in my sm-900p phone which I got unlocked for international GSM use (using from India) , it won't get locked again ...with all due respect to the friend who affirmed me already that it won't get locked ,can anyone else confirm that to me please ? I am not able to dare to flash the stock rom....since two days I am just waiting to take that step..presently I am using darkwolf rom but I want to flash with stock rom so that bootloader and modem gets updated and then on that version,I will flash this rom again ..that's my plan
If you mean will lock your bootloader, yes .
It will not lock your network again, if you already had a sim unlock/network unlock, it will remain as that even if you reflash, lock status is in a different memory not in the one overwritten by your ROM.
If you are talking about the bootloader, none of my motorola , samsung or htc devices relockes the bootloader once you have unlocked it, you have to manually relock it if you want to do that by any reason.

Xperia XA hacked. Worried about ROM virus.

Hi. Hope some Sony Xperia guru can help me with this.
I recently went on vacation and left my Xperia XA F3111 at home. Some a***hole had access to it for over 2 weeks and installed some malware on it. When I found out I factory reset the phone, but I really want to restore the stock ROM too in case he has flashed the phone with a malware-infested ROM which will survive a reset.
My problem is, the phone settings say "Bootloader unlock allowed = No". The guide here on XDA Developers say that this setting means he could not root the phone. My first question is, would this setting have also prevented him from installing a custom ROM?
If that would not have stopped him, are there any step-by-step instructions as to how I can reinstall a clean stock Sony ROM with that bootloader config setting in place?
Thx. D.
Hi, factory reset of the phone was the best choice. You don't need to worry about the integrity of the system as long as your bootloader stay locked so you don't need to flash it again.
For the malwares it's probably coming from crappy apps, for sample: https://www.google.com/amp/s/bgr.com/2018/11/25/google-play-store-apps-removed-malware-found/amp/
@rrvuhpg
Many thanks for your answer. The phone says the bootloader cannot be unlocked, but does this mean he could not have unlocked it, flashed a virus infected ROM and then re-locked it?
I mean, does that config setting mean that nobody can ever unlock the bootloader and change the ROM?

Yes exactly, almost nobody can corrupt the system (for now). If one day you see a TA dumper for locked bootloader on Nougat or a root exploit it will mean that your phone can be corrupted.

You people are foolish even more than me. I wanna abuse you but can't.
If your device shows Bootloader status unlocked allowed 'yes'
Then goto unlockbootloader.sonymobile.com
And select device modle and enter emi number and fu+k yourself and get an unlock code.
And use experifirm to flash any regions firmware even global too.

Please keep your temperament low, Mister.
And thank you for "misguiding" people. I unlocked bootloader, downloaded a ton of roms and none would flash. Each one of them results in errors. Downloaded any custom roms available, most go into bootloop while some wont install even.
Relocked bootloader and still wont install OTAs so I am stuck with stock MM with no possibility of getting Nougat because on SO-01H Nougat update is OTA only and there is no FTF available anywhere.
Thanks again. And please dont swear on public forums.

I am sorry for my misbehave with you people but keep one thing in mind and remember that forever I never misguided anyone in my life and here which I told you about unlocking the device was absolutely perfect ? and that was the only thing I told you and that's a childish work....

Thats OK.
I have no idea what jeffal jetwari is, but rest assured your advice was acted upon and it made me lose too many hours trying to fix it. No ftf's for other variants work, not even the global version, no custom roms work and there is really not much of a benefit having unlocked the bootloader. So please only advise on something you have experienced personally.
Regards
