My backup file was deleted after restarting the PC, now I have a problem with no sim card detect ...

Please help!! :cry::cry:
[Sony Xperia 1 Guides, News, & Discussion] MrCooper95:
Oh dear, first of all did you backup your TA.img? What Xperia phone is it and is it a japanese model? I don't understand how the backup file got deleted.
[Sony Xperia 1 Guides, News, & Discussion] Bemzter:
I borrowed someone's computer, it looks like the files are automatically deleted when it restarts.

After using the tool, I want to unlock ubl but my device is not detected.

I try to disable signature so that my device can be detected

After restarting the computer, all my data on the computer is lost.

My device is xz1 au (Japan)

Sorry bad english
[Sony Xperia 1 Guides, News, & Discussion] andyblessing:
Please can you kindly give me the steps to do the unlocking, my device is XZ1 AU, sim already unlocked but bootloader unlock status is "No"

thanks for the reply...
[Sony Xperia 1 Guides, News, & Discussion] andyblessing:
Please does this tool work on XZ1 Sov36..?

Changing BL status from No to Yes...

Need confirmation before I buy the code

Heard it breaks sim card functionality on sov36 model...

Have anyone successful changed BL status from No to Yes...??

Thanks...
[Sony Xperia 1 Guides, News, & Discussion] TrustAugustus:
I can only say it worked for me. AU(Japan) is a CDMA using network. While I used a GSM Softbank. While I personally don't feel there are many risks involved, I can't promise.
[Sony Xperia 1 Guides, News, & Discussion] vinodbad1:
I tried this on my Sony Xperia X5 (SO-01H Docomo) and yes, it did change the status of Bootloader Unlock Allowed to Yes from No. However I'm not able to unlock the bootloader of this device. Anyone else had any luck in that ? Flashtool returms error :

Tried with fastboot in Linux also which ends up in error. Dont know how to move forward. Anyone has any opinion on this ?
[Sony Xperia 1 Guides, News, & Discussion] MrCooper95:
Did you go to Sony Bootloader unlock website to get your bootloader unlock key? You have to unlock it with BLU option in Flashtool.
[Sony Xperia 1 Guides, News, & Discussion] vinodbad1:
Yes, I got the key from Sony website. Used it in Flashtool using BLU option. This is the log message I receive. The Root access is getting denied at the end. Device stays locked. Have given permission for OEM unlocking and USB Debugging.
[Sony Xperia 1 Guides, News, & Discussion] MrCooper95:
What really matters, is your bootloader has been unlocked now? Check in service mode and send a screenshot.
[Sony Xperia 1 Guides, News, & Discussion] vinodbad1:
I don't think so. Im unable to root or flash anything on device. It ends up in error. So kinda stuck now.
[Sony Xperia 1 Guides, News, & Discussion] MrCooper95:
Please tell me your bootloader status in the service menu. Have you tried using TWRP recovery and installing custom ROMs or magisk/SuperSU which roots the firmware?
[Sony Xperia 1 Guides, News, & Discussion] vinodbad1:
Bootloader unlock allowed : Yes

when i try to use TWRP it just returns error saying : Write Failed/Command Failed etc...
[Sony Xperia 1 Guides, News, & Discussion] MrCooper95:
Hmm, so the bootloader is not unlocked, looks like there's a problem with fastboot when you tried to unlock bootloader with BLU option.

What version of Flashtool are you using and try downloading the latest Android SDK, Z5 Compact driver etc... Although I assuming you know all about this.

I checked on the internet and some people with the Z5C just couldn't unlock the bootloader, they did everything correctly but nobody seems to have the answer or found the problem, very strange.
[Sony Xperia 1 Guides, News, & Discussion] uzalu:
I think I have this same problem with my XZ1c (ironically, I have a Z5c which worked fine when I unlocked its bootloader years ago).

I've used the qunlock tool and my XZ1c's service menu shows rooting allowed: yes, where before it showed no.

unlocking via the sony-approved fastboot method gives a generic failure.

unlocking via flashtool gives the following:

Spoiler content hidden.

Same error on both Windows and Linux. Flashtool 0.9.33.0.

On Linux, I put the unlock code in FlashTool/custom/G8441/ulcode.txt, but I don't think the process got that far.

Any ideas?
[Sony Xperia 1 Guides, News, & Discussion] jackma12138:
I Used s1 unlock tool and changed my bootloader unlock allowed from No to Yes, but when I tried use code oem unlock my XZ1 Compact, fastboot shows:

[Sony Xperia 1 Guides, News, & Discussion] greydi12:
excuse me i want to ask, i already boughtb the account in nugsm website. But until now (24 hours later) there's no email come to me. Is it scam?
[Sony Xperia 1 Guides, News, & Discussion] Ralyhed:
The server is down about 3 days ago,no further information about it.

I check with my Geek guys in Chinese Mainland they say they cant use qunlocktool too now
[Sony Xperia 1 Guides, News, & Discussion] Ralyhed:
By the way,anyone know wats going on with qunlocktool server and their team?
[Sony Xperia 1 Guides, News, & Discussion] TrustAugustus:
It's not a scam. I used it. Check your spam folder. Make sure you have the correct email address (in case you used PayPal etc and not your registration account)

EDIT: It seems to be down
[Sony Xperia 1 Guides, News, & Discussion] greydi12:
excuse me i want to ask, i already boughtb the account in nugsm website. But until now (24 hours later) there's no email come to me. Is it scam?

sorry, i want to ask i already got the code but when i plugged in to pc the software can't detect my phone
[Sony Xperia 1 Guides, News, & Discussion] TrustAugustus:
Interesting make sure you have the correct driver installed. There is flash mode and fastboot mode with xperia drivers. When using fastboot I have to reinstall the driver -every time-.

I'm not sure which the software requires.
[Sony Xperia 1 Guides, News, & Discussion] Ralyhed:
now the qunlocktool server back to work

My SO-01K(XZ1 DOCOMO)has been unlock
[Sony Xperia 1 Guides, News, & Discussion] greydi12:
my xperia xz (xperia xz s0-01j) done unlocked already using s1 unlock tool. but i can't ubl using flashtool. the code from sony website is input already. Where can go wrong?
[Sony Xperia 1 Guides, News, & Discussion] Ralyhed:
use 1234567890ABCDEF to unlock
[Sony Xperia 1 Guides, News, & Discussion] greydi12:
thank u so much, it work easily.
[Sony Xperia 1 Guides, News, & Discussion] MrCooper95:
Good news, another two japanese phones working just fine without breaking SIM function. I guess so far, Docomo or SoftBank Xperia models ( SO ) works with this tool without problems so far.

I will update the thread about this. Please let me know if you have any information.
[Sony Xperia 1 Guides, News, & Discussion] Ralyhed:
Mate from coolapk BBS told me if u have any signal problem you should write backup via the qunlocktool after unlock bootloader.

This will make root status back to NO but bootloader just been unlock.Nothing badly would happen.

And another friend told me qunlocktool maybe edited some ta to change NO to YES, that's would be the reason of some Softbank Xperia model has SIM problem

Update:I back to check, seems like only Softbank Xperia has SIM problem
[Sony Xperia 1 Guides, News, & Discussion] MrCooper95:
Aren't SOV Xperia models only from KDDI Corporation?
[Sony Xperia 1 Guides, News, & Discussion] Ralyhed:
Oh my bad,I make a mistake.SOV36 is for KDDI and 701SO is for Softbank
[Sony Xperia 1 Guides, News, & Discussion] jackma12138:
I got mine after two days, u gotta email them.
[Sony Xperia 1 Guides, News, & Discussion] wyzzy:
Does this still work?

Has anyone actually changed the bootloader from no to yes and then gone on to fully unlock the bootloader?
[Sony Xperia 1 Guides, News, & Discussion] MrCooper95:
Yes. There are users that already unlocked the bootloader if you read through the thread replies. What Xperia phone and model do you have?
[Sony Xperia 1 Guides, News, & Discussion] wyzzy:
Yes I read through the replies and saw that people had got the "no" to change to "yes", but a lot of people were getting errors when trying to unlcok the bootloader afterwards.

I have an XZ1 Compact, it says Bootloader unlock allowed: NO

I am waiting on a code from EE to unlock the network, but guess that wont change the above.
[Sony Xperia 1 Guides, News, & Discussion] MrCooper95:
I don't know what caused the errors from some of these guys. Some of it may be user related such as drivers, Flashtool version or a bigger issue related to the trim area, I may have to Google harder or get in contact with someone who knows more about the errors.

I suppose get your code from EE to SIM unlock it first and then try this at your own risk. I can't promise anything, worst case scenario is you lose £20.
[Sony Xperia 1 Guides, News, & Discussion] Rilic:
I'm getting a "no server found" error when checking credentials. Is the server down?
[Sony Xperia 1 Guides, News, & Discussion] andyblessing:
I really wanna buy this tool but my country doesn't support PayPal, I only have skrill account...

Is there any method to purchase this tool apart from using PayPal..?

Thanks...
[Sony Xperia 1 Guides, News, & Discussion] Rilic:
Still no luck on the "no server found" error. Can anyone else verify that it's down and not working?
[Sony Xperia 1 Guides, News, & Discussion] Ralyhed:
Well…Maybe just some Technical Difficulty, back and try next morning
[Sony Xperia 1 Guides, News, & Discussion] zskynet09:
Yeah, i think the server still down, mine had no luck as well. been trying to check credits, still got the "no server found" error as well. had disabled firewall as well for reconfirmation.
[Sony Xperia 1 Guides, News, & Discussion] Rilic:
Thing is, I'm still not entirely sure how this works. What server does this thing connect to? Or would that require a deeper explanation of GSM?
[Sony Xperia 1 Guides, News, & Discussion] zskynet09:
I'm not really sure either. But I believe the server thing is more like acting like authentication or granting access to perform the unlock service. The unlock coding is probably done by the software itself. I had been trying from 2 days ago (8 march), and seems the server still down until today. Also, I asked several other website operator who offer similar unlock and I quote that "It's on and off all the time, but without having an active credit I have no way of checking it. Sometimes it can take a day or two to come back online. it's not the most reliable of services, but it's the only option that works for most Sony's." Plus, there are several post on GSM-Forum members mentioned that "Most of the time working for me 9:00am-1200pm gmt +5.5" and " Try in this hours 1p.m, 3p.m, 6p.m , limit is reset every day", though I dont exactly know which region time the server would work. The lack of official support for the software regarding updates of the service or maintenance work status would mean we had to try it every single day without knowing when would the server back online. I also read that there is limit 150 account per day only. In the end, we can't really be sure the status of the server of qUnlocktool unless someone that related to the team could announce its status updates. Hmphh :(
[Sony Xperia 1 Guides, News, & Discussion] danidarklord:
woww, I just found out about this!
[Sony Xperia 1 Guides, News, & Discussion] zskynet09:
bad news guys, received this from website that I bought the account saying :

"Hello,

We have checked the situation: the qUnlocktool server is down for 2 weeks, due to maintenance works. That is the reason why we have suspended the sale of those credits."

Guess need to wait for 2 weeks from now. sad :(
[Sony Xperia 1 Guides, News, & Discussion] Rilic:
That's a yikes. But if it's what it takes, I'll wait!

I'm trying to unlock my old Xperia XZ that I've had lying around for about a couple years since I got my new phone. I wanted to try some funky Linux stuff on it, but obviously the bootloader is locked down tight. I hope that I'm able to unlock it instead of leaving it to e-waste!
[Sony Xperia 1 Guides, News, & Discussion] lotekatah:
Server still down until now. Tried to check credits every single day for the last 4 days. The CS guy on the WA chat tells me to be patient. . .
[Sony Xperia 1 Guides, News, & Discussion] zyva73:
Just found out this thread and that the qUnlocktoolserver is down at the moment... it seems I have to be patient as well ! I will follow this thread so please post updates if you have any
[Sony Xperia 1 Guides, News, & Discussion] Rilic:
March 20th. Server still down :/

Hopefully they can get it back up and running in the next week or so.
[Sony Xperia 1 Guides, News, & Discussion] lgoxvxe:
It seems that the server has been down for two weeks
[Sony Xperia 1 Guides, News, & Discussion] saraththaliyil:
Does the same happened before?
[Sony Xperia 1 Guides, News, & Discussion] lgoxvxe:
The server has been down before, but it doesn’t seem to have been so long
[Sony Xperia 1 Guides, News, & Discussion] Rilic:
Alright, I can check how many credits I have now! Seems back up.

However, I still get this error when trying to unlock:

Checking for signature ...
Waiting for calculation process ...
remote dongle not available
signature calculation not done,err: 144
UNLOCK FAILED

Any ideas? Is this that magic phones-per-day limit I keep hearing about?

[Sony Xperia 1 Guides, News, & Discussion] zskynet09:
Yea, i can check the credits too. Probably the server just starting, it maybe not fully up yet. Or theres many of us doing the same haha, so hit the limit.
[Sony Xperia 1 Guides, News, & Discussion] Rilic:
Has anyone had luck with it yet? Server is definitely up, it's just going to error 114 whenever an unlock is tried. It doesn't take away your credit for trying, so it's just a simple error.
[Sony Xperia 1 Guides, News, & Discussion] Splash1.17:
It took me about 3 hours to unlock my Xperia1, but it didn't work. Always prompted recv error [10054] and remote dongle not available.

Back to square one again, I guess. Totally disappointing. Really unreliable service ever.

Try to search on google "sony xperia cable unlock- 0 counter credits" and you will find a lots of websites selling it, find the website that you trust. Price may vary according to the websites. Many suggested to buy from NUGSM with about £23.94, while I was able to find about just £20 from unlockingshop.co.uk with friendly owner & fast response email, thus easy to communicate regarding my order and the qUnlocktool status. Choice is up to you to find any websites you trusted. Cheers, regards.

Use Flashtool for bootloader unlocking, you bootloader is not unlocked yet.

Please do not ask NUGSM questions about the S1 Network Unlock Tool relating to bootloader unlocking. They only provide the credentials and the tool, as they do not know much about the Xperia bootloader unlocking.

[Sony Xperia 1 Guides, News, & Discussion] MrCooper95:
I have seen this specific error before from another user but I dont know what is exactly causing the error, no one seems to have answers on google search. Try using a slightly older flashtool firmware like ( 0.9.25.0 ) if you on the newest.
[Sony Xperia 1 Guides, News, & Discussion] zskynet09:
Have you tried getting the unlock code from sony website? Mine doesnt work with the flashtool, so I ended up trying getting the unlock code from sony website, and it does work and unlock my phone's bootloader.
[Sony Xperia 1 Guides, News, & Discussion] sa4zet:
First of all: Thank you for your help.

I tried different older versions. With 0.9.25.0 both on linux an windows the flashtool stuck at "Sending Sync" and the phone stucks in flash mode, I have to hold the UP+POWER button on the phone about 3 sec to unstuck it and kill the flashtool.

Yes I have the unlock code, but I'm stuck before anything ask for any code...
[Sony Xperia 1 Guides, News, & Discussion] zskynet09:
My advice was that you try using the adb fastboot platform tools (refer to Sony unlock bootloader guide), boot into fastboot on command prompt on windows (power+vol up) until blue light appears on the notif led. then put this command on the cmd

fastboot oem unlock 0x<insert your unlock code>

And you should good to go. Hopefully it helps.
[Sony Xperia 1 Guides, News, & Discussion] sa4zet:
I tried that before, but I always kept getting this error:

└› fastboot oem unlock 0x##################

FAILED (Write to device failed (Cannot send after transport endpoint shutdown))

fastboot: error: Command failed

But I tried again now (after trying BLU from flashtool which was unsuccessful)

└› fastboot oem unlock 0x##################

fastboot: error: Command failed

So something changed... I tried without the 0x

└› fastboot oem unlock ##################

Finished. Total time: 0.077s

And after that, the phone went blank. I tought I bricked, but holding DOWN+POWER about 20 sec helped and the phone started to boot, and the first screen tells me:

"Your device software cannot be checked for corruption.

Please lock the bootloader"

So I guess the bootloader unlocking was finally succeeded! :) :) :)

I guess the qUnlockTool got updated. Wasn't able to proceed with the one linked in first post. It returned me the following error:

*snip*
Checking for signature ...
Waiting for calculation process ...
unspecified server error [0x16]
signature calculation not done,err: 144
UNLOCK FAILED
*snip*

In my search figured that a new version of the tool has been released.

Reference: https://www.imei.us/productsandservices/server

Screen cap of the page:

Download link in screen cap: https://we.tl/t-0KJBEr2rEV

From that description, looks like the above error is from using an older release. Tried with the new tool from that download link, still an error though, will try later and revert:

*snip*
remote dongle not available
signature calculation not done,err: 144
UNLOCK FAILED

The interface has got some updates. It now has three unlock buttons SIM unlock, FRP unlock and MLR unlock. I suppose I should be doing the "SIM unlock" hoping that this would be the same as "Unlock" button on the old tool and hope to have the Bootloader unlocked too. If anyone knows, please comment.
[Sony Xperia 1 Guides, News, & Discussion] zskynet09:
Sorry, don't know much about the new design & functionality of new updated qUnlocktool. But did you tried the "SIM unlock" button and had the bootloader status changed to yes? I had 1 more xperia device (pending arrival from seller) to unlock it and was hoping for your feedback on the experience of new qUnlocktool.
