It happened a couple of months ago when I accidentally relocked my bootloader through the Flashtool instead of Backup TA , wifi and bluetooth became inconsistent and kept on crashing the phone. It sometimes starts to work for a short period of time , but then phone crashes and it doesn't work again for a long time and sometimes on a random reboot it starts again, only to crash the phone.
Here's what all I have tried...
1.Going back to stock ROM and relocking bootloader through restoring TA. (But it didn't help , its worse on stock ROM my phone freezes and I have to go back to custom ROM)
2.I visited the service centre after doing a software repair and relocking it.(They told I might need to replace the motherboard to get it right , its 10 thousand rupees making it senseless option)
3.Tried to look into phone's important files related to wifi and bluetooth to see if something can be done( I don't have enough coding knowledge so I couldn't understand much)
I need help of kernel developers or anyone with knowledge on this topic to kindly help me. I have my TA backup with me. I am ready to provide you with any logs etc. you might need to diagnose the problem.
Thanks in advance and please help me out :crying: :fingers-crossed:

Okay, first of all I have unlocked my xperia L and other Xperias via Sony the first time and later have unlocked and relocked my bootloader via flashtool numerous times without using TA at all. I never encountered any problems with WiFi or Bluetooth at all till date as you mentioned.
TA has important files which tells the hardware how to be integrated as one unit. (Ram, motherboard,bluethooth etc information) . It is highly possible that you might have corrupted some part of it or you might have a faulty hardware.
I suggest, using a different PC to unlock and relock boot loader using flashtool. This is to ensure no old data is added or removed.
Also, try unlocking using official Sony way and report back. This you can do using the same PC you are using now.
If you ever made an FTF from your phone, flashing that can help as well because at times "data" contains fikwa that can fix Bluetooth and WiFi.
Try using my ftf and see if it helps . you'd find it in general section maintained by @Joel16
@Hnk1 okay thanks I will try unlocking and relocking again ,as I have a newly formatted PC now (I had tried this unlocking-relocking once before but in vain) .
And I don't think flashing FTF is helping in my case , it is only making it worse.
Still , I'll try and get back to you

@Hnk1 hey I tried everything you suggested , but nothing seems to be solving my problem. I tried it with a formatted PC. New Flashtool installation , flashed the ftf also , several relock and unlock cycles later too no progress.... any other thing I may be able to do to fix it?

I suggest you go to a guy who knows "JTAG". I think that's the only way you can revive your motherboard of its a corrupted TA on your phone. Else it could be your hardware.
Research on JTAG and how to find the right guy.
Good luck !

Hello everyone,
I have learned a lot from these forums and am thankful for everyone's hard work here. I have a Tipo Dual that was originally with firmware 11.0.A.6.5 (ST21a2, not i2). I installed GIMLO, which is generally good, but I have some issues with it (LED doesn't light for E-mail or charge, play store and games crashing, little things like that). The phone is rooted and boot loader is unlocked (all with tools from here!). I did not make a backup of my original system before I flashed (I thought I had, but it is not there, not sure how I failed at that).
I have two questions: I have tried a lot of times to relock my boot loader so I could use SUS or PC Companion to reload the firmware. It won't relock with any of the methods I have found here. Is there a reason for that? I have reloaded a stock firmware, and even then I could not relock boot loader. Anything I should look for to allow this?
I would like to put the a2 firmware back on but the firmware I find here is always the i2 version; I understand the difference is little tweaks in how the phone deals with the GSM network, and as phone connectivity is important to me, I'd like the original a2 version again. My wife has the identical phone (with ST21a2 & 11.0.A.6.5 -- or maybe 11.0.A.8), and she has not done anything to hers. Can I root, make a nandroid backup of her phone, and somehow import/flash that to my phone? I have my contacts backed up, so I'm not worried about that, and I have all my apps, so a clean install would be fine with me. If I can do this, how do I get the backup off of her phone and onto mine? Am I right in assuming that if I manage to do this, it will replace the kernel, too (I currently have the gimlo kernel)?
Do the experts here have any advice for a noob on these two questions?
Thanks, and thanks again for all your hard work here!

Yes the nandroid backup would be fine but you will need to reflash the stock kernel with flashtool i don't no if theres any difference between the kernels of i/a. plus even if you relock your bootloader you still might brick your device flashing with Seus & pcc.

Thanks for responding to my question, I appreciate your help.
Do you think it's better then to just do something like flash this if I want to go back to stock:
http://forum.xda-developers.com/showthread.php?t=2270976&highlight=+tipo+dual+
and just forget trying to make it retail again? As long as Sony doesn't change and bring out an OTA/PCC update to JB, I guess there's no reason to worry about anything else in being bootloader locked, right? Especially if I can brick the thing by trying.
This is all very new to me (if I'd realized the limitations of the Tipo Dual and cm10, I would have bought the Tipo single!), but I hope to be able to play more with Android and with roms because of this excellent forum.
Thanks again,
Fred (no, not really)

If thats the firmware you want then by all means flash that bro. The nandroid backup from your wifes phone will be just the same. the backup will be on her sdcard in the file /clockworkmod/backups/ just copy it and paste it to your sdcard. restore it then flash the kernel.
There's an ftf file available im the forum to relock the bootloader.
Flash it in fastboot mode.
I myself have flashed it to relock the bootloader on my st21i2.
After that use pc companion to get your firmware.
I have relocked and then used pc companion without any problems using this method.
Should work for you too.
All the best.

Thanks, c4cyro; I managed to relock with flashtool (it had not worked when I had tried before, but suddenly it did); even so, I can't load from pc companion. Did you also unroot your phone? I've seen elsewhere that that can have something to do with it. I'd like to do this just because so far I haven't been able to (and I hate not being able to do stuff, even when I'm a noob).
Thanks again,
Fred
no i did not unroot. if sony pcc does not recognise your phone, you should try doing that on another system maybe.
to unroot you can use "unlockroot" program.
also, did you check this? http://forum.xda-developers.com/showthread.php?t=2001567

I wonder if it's because it's a Tipo Dual, and the firmware that Gimlo is based on for the Dual is the latest (11.0.A.6.8); even when it's locked and unrooted, pc companion just says it doesn't have any software for my phone. Really strange (and annoying). I might try loading an older firmware, locking everything up, and trying again. Or maybe I'll just reinstall Gimlo and see if I can get it to work the way I want it to!

It picks it up as Tipo Dual (listed as St21i2 instead of St21a2 bc the Gimlo .3 firmware -- which is the right one for the dual -- is the "i" version).
I've just found this firmware, which seems to be stock, so I'm going to try this:
1) try out this firmware (http://forum.xda-developers.com/showthread.php?t=2044944; 11.0.A.6.5 stock) and see what it is and how it works;
2) then install the base stock for the Tipo Dual for Gimlo (which for the dual is );
3) then install the Gimlo firmware and ROM, and see if I can get it to work the way I want (going mostly stock except for the loader, which I really like the one I'm using on Gimlo);
Will report back on how things turn out and what I end up sticking with!
Thanks again for your help, it's good to feel like I'm not hopping about on one foot on my own.

I suppose you should do the following. Considering you have unlocked your bootloader via Sony/flashtool. (Sony preferable)
Flash latest stock using Flashtool. 15.3.A.1.17
I found this Download here
The wifi should work after that.
Then you should download any custom ROM. Extract the zip and find boot.img
Flash boot.img via flashtool again. Then flash custom Rom Zip (without extraction) via recovery!
Good Luck

I am glad I could be of any help!
Well, you can use any 15.3.A.1.17 ftf file depending on the region. Usually you do not have any problems apart from supported languages on your phone if you flash some other FTF file apart from your region.
Basically, you will need to download both the files and then you will need to extract them both to find one FTF file. from the link i shared. However, you can flash any FTF file with latest version x.x.17. Make sure you flash FTF made for your own device or you may permanently brick your phone for good. The link I am sharing below is for Xperia L
Here is a place where all the FTF files are compiled together by @Joel16
FIND IT HERE
The guide to flash an FTF file is as follows :
Look here
Remember the guide i sent you is for another device but as long as you flash Xperia L (taoshan) FTF file, it would be fine. Also, you would need to flash everything including kernel.
Good Luck and tell me if you need anything more at all!

I see that you helped the OP get through Wifi problem , but I am also having same problems , maybe more.
I clean installed many different ROMs , including Flashing the 15.3.A.1.17 Stock ROM.
I tried even different KK kernels and JB kernels(for Stock ROM) , but no luck.
Plus I have also tried flashing a kernel through Flashtool and reflashing it from recovery , but my Wifi doesn't work and after a hell lot of reboot cycles , I sometimes manage to get it on , which eventually turns off after crashing the phone after some indefinite time.
Please help.

First of all, how did you unlock your bootloader?
Secondly, when you are flashing an FTF, have you flashed any FTF for a different variant ?
Like if you have c2105 and you flashed c2104 ?
What about your WiFi bug, tell me details about how it started and what kind of error do you get. The more the details, the more you are helping yourself out .
Lastly, is your device in warranty and can you claim it for an exchange if you relock your bootloader?

Bootloader was unlocked through Flashtool from Androxyde.
Wifi problem started when I was using something like FXP 325 , that would be a couple of months ago , but then it was minor , just a reboot would do.
But now I have tried many ROMs(of course clean installed) , kernels(with essentials wiped) , also stock ROMs (.26 ,.12 ,.14 ,.17) all show wifi problems.
By that I know that its a user specific issue. My warranty is over , but I will have no problem paying a bit with relocked bootloader if repairs are needed.
But if there's a way I can fix it at home , please tell. And yeah , I always flash C2104 files as mine is C2104.

I think you should boot into recovery and do a full wipe including internal/ dalvik/everything including SD card. Don't just factory reset but do a complete wipe. (Twrp has that option. In other recoveries usually you have to do it individually.) So go in recovery and wipe everything you can see that could be wiped.
If that doesn't work,
I suggest you relock your bootlader and see if that helps.
Also try to relock bootloader and unlock it via Sony official way. See that works for you or not.
Seems like a software issue most probably because I'm afraid you didn't backup TA while unlocking bootloader and sometimes the keys are lost and it causes some problems like WiFi. Also, the reason is more likely because of the fact that you didn't do it officially. it could be hardware as well but that's very rare. I would suggest that only give it to someone who knows hardware quite well.
Update me what happens!

Well, I would say that this happened due to unlocking your bootloader without a TA backup. I am afraid there isnot much you can do as every device has a specific TA code and I am not sure if someone would be interested to share TA backup with you. Even if they do, I am not sure if it would be helpful.
I would share you with all the options you have got :
Go to question/answer and ask for TA backup from someone, this wouldnot work mostly and I would tell you to do everything with caution and on your own risk but that all that could help you out for now at home really. Try someone else TA and see if it is accepted and the WIFI starts to work again. (But use it as a last resort)
If I may add, if you can get a Jtag guy, he might be able to fix your device for a cost but I am not sure of that either.
Another option for you would be asking an expert to repair your phone and telling him all about TA/ unlocking bootloader. If he understands what you are talking about, it just means he knows what you want him to do. If he doesnot, it probably is a bad idea to pay him. You can add it could be a hardware issue as well just in case. However, some times those people use different sort of cables tools to flash FTF so maybe that could be helpful. You can say, you would only pay if WIFI and bluetooth starts to work again! (Second best option ??? )
I honestly do not know how to solve issues related to TA I also suggest write in Xperia Z1 / Z / Z2 forums about your problem as I remember that many of them had many issues due to unlocking bootloader. Sometimes unrooting solves the problem as well. I think that forum users be able to help you much better! Make sure you add all the details about how it happened, what you did and which device are you using and how everything you tried so far hasnot worked. Make sure you mention all tips you got and those that didnot work for you!
Good Luck!

bro I think I got it , I absent mindedly relocked bootloader through Flashtool , as I was going back to stock after months . I do have my TA backup.And I will restore it and see what happens. Thanks you just made me remeber that
Hi guys
recently bought a s6 from ebay which was frozen on S6 logo. Basically managed to clear cache and factory reset from recovery but that didn't work, anyway I DL the O2 firmware and odin and put it into download mode I get a fail on odin when trying to install the rom
The phone has knox 1 and also has red writing SW Rev. Check Fail. Device: 3 Binary: 1.
I'm unsure what to do and if theres any chance for me to recover.
Many thanks
Mav
it failed because you flashed an incompatible Firmware.
where did it stopped flashing in odin? In sboot.bin?
If thats the case, you need to download proper firmware/country for your device.
Let me know what country is ur fone made of.
Hi thanks for your reply.
I managed to get it working by installing root and unikernel, it boots into O2 the firmwarw is 5.1.1
Only problem now is imei is 3500000000006
And it wont make calls dont know if imei is corrupt ir they sold me a stolen or lost phone?
I may install tw recovery and custom rom and see if that works.
Any suggestions?
Hi
Ive managed to sort out and get it to work infact typing on it now. Its currently rooted custom rom and twrp. I e managed also to restore original imei number so overall im quite pleased with myslef lol.
Anyway one last problem i have is ive tried all sims but none work i know ita picking up signal as the bar shows top right. Also chexk my settings.
Ive tried automatically and manually going to register networks but it says unable to connect try again later. I know uts not my area as my wifes s6 works perfectly. Sim also def works. The phone also picks up when a new sim has been inserted so i dont think its sim slot.
Any ideas guys
OK new update if anyone can help I'd really appreciate.
Installed new vador rom Imei reverted back and serial number is all zeros
Is this something to do with baseband if so how can I fix read somewhere about ariza patch but that was s3 4 etc.
Thanks

1. Your EFS is corrupted. The IMEI you see is a generic one, phone will be useless for network provider only wifi will work.
2. The one thing that caused this is by flashing an old bootloader to your phone. Thats why youve encountered Check Fail error on Download mode.
Happened to me also but got it fixed in the end.
OK thanks for the info how do I fix? I do have my wife's s6 but that's not rooted and don't want to root can I restore the efs
Many thanks

Been searching for ages can anyone please point me in the right direction for a fast download of stock o2 5.1 rom? I believe I may need this one G920F_O2U_G920FXXU2BOGC_G920FTEF2BOG1.zip at the moment rapid gator is going to take 10 hours lol.
Thanks
BTW is anyone out there on the s6 forums hardly getting any help really want to try and sort this thanks

I think I know one thread that has a firmware downloader with ultra fast download speed you may try searching it.
I dont know if it will help, but you may be able to successfully flash the firmware but many of those who have problems were unable to boot the phone due to corrupted efs data.
Here's my way of fixing it (if you still have intact efs). http://forum.xda-developers.com/showpost.php?p=63693480&postcount=28
But if its already wiped, there's no way you can retrieve it unless bringing it to samsung or any repair shop.
Anyways, mine was fixed (IMEI) using Octopus box repair tool. Since I cant do anything to recover my generic imei.

Thanks silly question but how do I know if my efs is ok or corrupted?

As far as i know if your EFS partition is corrupt and you do not have a back up of the EFS partition to restore which you probably dont as you bought this as broken then sim capability is dead, im not sure of any other way to fix this unless you have the intact efs partition
Hi
How can I tell if the efs is corrupt it shows a baseband it now shows the correct ime I
It just won't connect to network it says try again.
I can post a screen print of efs folder on es Explorer if anyone knows what it should look like
Here are screen prints but I think I'm speaking to myself lol
Hi there i spent months on fixing issues like this (i now have a tool that takes care of all this) , best thing you can do is flash to a rom where the original imei came back do a backup of the efs, flash to a orginal rom ( latest rom) make sure its the right one for your device, connect to kies, install the rom again root and restore the efs failing that the imei is blocked use checkmend.com the uk version if your from the uk, message me if you need help

Your rom, recovery and kernel doesnt have to do with corrupted efs.
Only way is to bring it to repair service using box tools to re enter/validate your imei so that you can connect to your network provider. There is no other way around other than retrieving your efs and installing it or thru repair service.
You may now relax yourself at finding ways to connect, I assure it wont help trying to flash and flash and flash stuff to your phone.

Uhm can you send sms or make calls? It seems you have a valid Imei
Ok ive tried all stock roms including o2 and a uk btu one but no luck they all do the same thing get frozen on Samsung logo then I flash unikernel and it boots.
When checking my efs folder I can see no modem file I'm now wondering could that be the fault? so I downloaded modem and BL for 5.02 and 5.11 both will not flash via odin I get a fail message and on device check fail device: 3 binary: 1 messgage in red?????.
So I'm a little lost, I was wondering if I managed to root my wifes s6 which is virtually new could I back up her efs folder then copy it into mine and just amend the imei to my original would that work? also is there a way of rooting my wifes phone without triggering knox?
Any other suggestions guys I really don't know what bootloader was on it to start with or rom is there any way for me to find this out?, also another weird thing when the o2 uk roms install they install german apps?
Thanks guys
Ive repaired EFS Partitions with scripts downloaded from links at xda.
For example i trashed my EFS partition on my note 3 so it caused hard reboots after android booted up and it couldnt be fixed with anything else than the EFS partition repair scripts.
Edit: friend repaired his Note 4 also.
Thanks but where can I find these scripts as I've looked everywhere and if I did find how do I go about doing it. At the moment when I try to flash modem and bootloader it fails.

Same with me also need help
So I have a problem with my phone [d2303] is just indicating that there is no SIM card. This ONLY happens on the stock lollipop rom. I'm currently on slimrom to test it but I will revert to stock. No the cyanogenmod rom isn't stable enough for me and I don't like kitkat even dough it fixes problems such as bad camera quality... And NO tis isn't just me. I know someone with the same problems but on KitKat ( he's too lazy to update). Recently I've been also getting some errors while moving files to SD card (with the automatic function and manualy). If it helps I can post some screenshots of the problems if it helps....
I'm starting to get frstrated with this phone and is it a software or hardware problem? Should I take it to service and if so will they accept my phone because I have allredy unlocked my bootloader? Is there an efficient method of relocking a bootloader (links to posts are enough)? I've used the flastool method to unlock the bootloader on my phone(link- http://forum.xda-developers.com/showthread.php?t=2743694).
Is anyone having the same problems?
I also have some experience in rooting and installing costom roms on a few phones so if you know a software solution or a fix I won't have problems installing it.
I am thankful for you at least reading this thread. Also thank you for all your responses in advance.

Did you used flash ftf? I think main reason is you didn't flashed baseband. If this still happens, go to the service with relocking bootloader. I went to the service for dead pixel with relocking bootloader, they swapped my device.
This started appearing before I flashed any rom or unlocked the bootloader, so basically when the phone was stock. Also I'm not sure what is a baseband. I flashed a tft from a xda post with a youtube video with downloads for all android versions and xpria m2 models. The problem seems to be less frequent if I don't use the phone as much. I'll tryt his method: [It's on techbeasts but i'm not alowed to link outside links yet] to restore to stock and relock bootloader maybe even kitat since it has better camera quality. If the problem doesn't go away I'll take the phone to service because I want a reliable phone.
Thanks for the reply I almost gave up on this post. I saw a lot views but no replies this might mean that a lot of people have the same problem.
I'll also post some status updates about my problem so this post can be as an instruction to people with the same problem.

This phone's problems not limited with sim card, also screen, camera and many more. M2 series are not good.
Don't agree with you sorry, my m2 hasn't missed a beat in over a year of serious use apart from when it's something I've done to it myself tweaking and changing things maybe I've been lucky even gonna keep it when I get my upgrade in a few months(Xperia of course).

I love my 2303 too, but I used 4 m2, this doesn't mean all m2's are damaged But mostly of them are little produce damaged (Example, when you pushed screen on normal touch, you can see LCD liquid moving or find dead pixels)
hello, i am new, and first of all sorry for my bad english
so, everything started when i got my xperia Z5 a few days ago, however i got the USA version. The fingerprint scanner is diabled in this version so i decided to flash my phone. i unlocked the bootloader succesfully, then i flahsed with an USA custom firmware wich i downloaded from xperifirm (i have to say that i replaced some files in the USA custom firmware with the same files from another custom UK firmware bc it said so in some thread i read to re enable the fingerprint scanner) anyways, everything worked fine, i mean not really, the fingerprint scanner did not work and other problems came up
I live in central America so my phone wouldnt recognize my sim card anymore, fine, i thought i could fix it, so i donwloaded another firmware that was for my country, i connected my phone to my laptop, and starting flashing this new firmware and when it was like 90%, it just got stucked for a few minutes so i pressed the "flashing" button again and suddendly the flashing was aborted, so guess what ? now when i try to turn on my xperia Z5 it just says "the software update failed make sure that your phone is connected to the computer and try again". ok i can fix this i told myself, with pc companion, but it rutns out that because i unlocked the bootloader, it can NOT be fixed, so i have no idea what to do , please tell me theres nothing left to do. please help me, i even tried re-locking the bootloader using flashtool, but it keeps getting stucked midway so... i can not do anything. i am afraid that the battery can run out, bc every time y try to charge it, it just keeps happening the same thing (this loop where it says that the update faled and then it turns off, and then on again and it repeats.
i really need your help guys. and sorry again for my english:crying:
Thankyou
