[Q] No Network

Hi everyone. My friend and I tried to flash a custom rom to his Xperia S. so before that we have to root, install recovery and etc.
we succeed on flash everything but that's what we thought. We noticed that the phone doesn't have any network, tried different sim and both from different networks are useless. So we Read and we still can't find any solution.
the phone IMEI is intact
the phone is sim unlocked
the baseband is 8660-AAAABQOLYM-313065-39
the phone is on .96 FTF
we already tried to revert back to .96 FTFs I think the baseband is not compatible with our country Philippines.
we already tried downloading the .96 customized PH FTF from Xperiafirm but still there's no luck.
we already tried repairing through PC companion
we already tried flashing FTFs .200 .211 and.96
Can you help us?

Did You flash a stock firmware using flashtool version 0.9.19.1? It causes sim lock while flashing. It was brought to attention when same problem was aced by other user. Quoting him below.

Tried many stock FW and found the reason of the recent problem happened to many people all over the world. That's flashtool-0.9.19.1 which contained some script errors which lead to bootloader locking and loose of network connection

thanks for the immediate reply. What should we do then? just flash a stock FTF using flashtool with different version from the ones you stated? or we can still use the 0.9.19.1 but we have to exclude the simlock?

That's no use bro. I've tried many Stock FW as well as many versions of Flashtool after getting same problem with my phone. As Flashtool creator wrote "The only way to recover from locked phones is to reactivate them in a service center or to restore the 07DA unit". So, if you don't have TA partition backup made prior bootloader unlocking then you've got an alarm with camera & mp3 player made by Sony. The ASC propose to replace the whole motherboard.

Are you sure your phone is Dual Sim ? i think b150 is for single sim check here and follow the correct numbers to update your phone to MM.
As per rooting the phone, you'll need to be more specific about why you are unable to do it, you can't obtain the unlock code ? or you can't get the connection through ADB ? or somethig else ?

Already emailed the huawei support but they asked me to just use the website. I really wanted to root this device to use TB. I tried flashing all latest frimware single sim or dual sim version but still no luck updating to MM. So my plan is to just root this phone and flashed RR and flashable stock rom available on the thread via TWRP. Is there any other way to get the bootloader unlock code mate? If there is no way to get the code, i plan to just sell this phone.

I successfully updated to MM now im searching for root. Can someone here help me to get the bootloader activation code using your account? I cannot open the unlock page. Please help me.

Nvm. I already rooted my device

[SOLVED! ^_^][H930DS ONLY] V30+ Progress Towards Root/TWRP/ROMs (not achieved yet)

The plight has been answered! We have a solution! Thread has been locked, as we now have a solution! Please visit @ChazzMatt 's posts in this thread for a full description, and link, to the method.
---
G'day everyone!
Much like @mr turtle droid , I've decided to create this sister thread to keep us all informed of the progress towards Root, TWRP, and ROM's for the CARRIER UNLOCKED LG V30+ variant.
At this point in time (15:50, 21st Feb 2018), LG HAVEN'T placed this model on their Unlock list, on the LG Dev website. The LG Models that ARE there are the H930 and the H930G for the Euro market. I've emailed LG Australia about this, and am still waiting on a response, but doubtful I'll get a helpful one. I've also asked on the LGDeveloper twitter page, and received a stock standard response: "We are sorry that we can't be of much help. If there are any changes to the supported devices, we will let you know via our website".
Not being a dev myself, I don't know if any fastboot commands work or not, so if someone can get us going with potential methods, that'd be sweet.
I have a link for the Firmware *.kdz downloads, for what it's worth. Link is found HERE.
If anyone has any ideas, please share them. The more that we know, the closer we get to unleashing the full potential of this great phone.
Also, if someone could explain why exactly LG doesn't unlock all the different models of their flagship, or at least give an ETA for the unbranded one's, that'd be sweet. Is it because of licences, or patents or something? Or is because it's a Dual SIM model? Curious more than anything.
It just seems nuts to me that the V30+ that I bought from JB Hi-Fi wouldn't be on the unlock list, if it's an unbranded / noncarrier variant.
Once again, this is for the carrier UNLOCKED variant, H930DS.

If the bootloader is unlocked on the H930DS then this thread might be a step in the right direction for route

Hi, reports on there suggest that only one sim is working after using that method.
Seems like flashing back some partitions from another ds model with lgup could be the solution.
I have been tempted to buy this phone only put off by no root.

Is second sim not working at all, or is it possible to use it as a data connection only?

Hi, I have only had mine for 3 days so haven't tried yet
I think as a H930 single sim unlocked bootloader is loaded, you will only see 1 sim.
Dont quote me on that as I am still reading up
Any experts who can answer?

Both SIMs work for H930DS. Just flash unlock bin and TWRP as described in WTF thread. Need to mention that I've had official H930DS Oreo update prior to attempting this.

Hi, well thats the first time I have seen that stated.
There are no specific instructions for the DS.
Are the one's with only 1 sim just flashing a single sim rom and keeping it for the bands or something?
I have V10e-AME-XX and no Oreo update is showing.
So do I
LGUP to convert to open single sim H930
Adb reboot bootloader
fastboot flash unlock new_unlock.bin
Install Twrp
Then how to get dual sim rom?

I wouldn't flash single sim rom on a dual sim device if I was you. You need to flash Oreo dual sim firmware and then everything is straight forward. Bootloader unlock process as well as flashing TWRP won't effect any fuctionalty and procedure is simple.

Is H930 eu 20d a dual sim rom then?
Otherwise what exactly is "Oreo dual sim firmware"

Thank you. So you flashed the H930 Oreo KDZ. Just like the instructions say in the WTF thread.
To me, the only way for H939DS users to do this is to flash H9390 and run the command. One India H930DS user says that is what he has done and he has BOTH SIMS. Now you have confirmed it. That's two H930DS users who have bootloader unlocked and rooted, just like I said they could do -- and they both retained dual SIM functionality. Every V30/V30+ can be bootloader unlocked and rooted, except for the T-mobile H932.
Even @crubbish seems to infer that but he contradicted himself -- saying he didn't flash the H930 firmware, which I'm pretty sure HE HAD to -- which is frustrating.

hmm, so I have just re-run LGUPP and device is recognized this time but I get and error 0x8... Please us latest dll LAF protocol version is not match
Do I need to go back down to nougat and them back up again?

No, the H930 variants (which include the HD30DS) do NOT need to downgrade to Nougat.
You just need to figure out how to install and use the LGUP.

@crubbish, I'm sorry but you seem to be contradicting yourself. Please clarify. You either used the WTF instructions or you didn't.
I WROTE the instructions for the WTF thread and they clearly say all H930 variants -- which included the H930DS -- needs to flash the H930 Oreo KDZ to get the fastboot flash commands. So, unless you are saying you somehow managed to enable those commands some other way (and H932 T-mobile users would be all ears for that!), then you did indeed flash the H930 Oreo KDZ, did you not?
Two other H930DS users -- at least one from India -- have used the WTF method, of course flashing the HD30 Oreo KDZ -- and they are bootloader unlocked, have TWRP custom recovery, rooted, and have dual SIM functionality.
Unless you have figured out some other way, THAT is also exactly what you did.

If you've connected the phone to a USB3 port, try a USB2 port instead. That usually works.
Also, if you're not using the cable that came with the phone, try that as well.

No, you need a newer DLL for LGUP which can be found in this thread: https://forum.xda-developers.com/lg-v30/development/lgup-oreo-dll-file-v30-t3779441
Put it in the C:\Program Files (x86)\LG Electronics\LGUP\model\common (create the "common" folder if it's not present). Start LGUP WITHOUT Uppercut.

Thank you.
Besides trying a different USB port or different cable, also try to enter download mode manually (power off completely, then hold volume up button while plugging in USB cable), THEN open LGUP to make it recognize your phone.
Also, try a different computer if none of those suggestions work.

I've had Oreo OTA flashed on my H930DS after which I've followed WTF procedure without flashing any other firmware. Sorry if I wasn't clear on this.
It looks to me that as long as you're on official Oreo firmware you can appy unlock.bin straight away, no need to pre-flash any other firmware. Also someone has reported on losing dual sim functionality after flashing plain H930 firmware, that's why I think it's safer to flash specific dual sim rom for dual sim devices.

[GUIDE] Flashing XQ-AT51 Firmware on XQ-AT52 Device

Disclaimer: I am not responsible for any bricks/ issues you may encounter following this guide. Although, I will do my best to try to help you if something were to go wrong.
MAKE SURE OEM UNLOCK IS ENABLED UNDER DEV SETTINGS BEFORE YOU DO ANYTHING BELOW
Update 2: 3/11/2021 : I see maybe deleting the .ta files may help avoid soft bricking, feel free to try it I have not personally tested yet to see if it works.
Update#3 3/13/2021 : If you are following this guide recently make sure you update to Android 11 first! Do not do any updates after the first one to Android 11! Then the flashing should work just fine. Tested and verified this on Taiwan XQ-AT52 to 51 firmware
Hello, I've managed to successfully flash AT51 firmware on my AT52 without issue using Newflasher.
Step 1 download = the US firmware/ whatever region is needed for you and new flasher/ the sony xperia drivers needed to flash the firmware to your device. Extract it to your desktop. Install the Xperia driver from newflasher if you need to/ haven't yet. Newflasher needs to be extracted into the same folder where the firmware files are that you downloaded from Xperifirm. This step is crucial!
Step 2 : Power off your Xperia and put it in flash mode by pressing down on the volume and connecting it to your PC via usb. (Do not use the USB C cable that came with the phone use a different one if you have one) You'll know it is in flashmode if the notification LED turned green and the screen remains off.
Step 3 : Open newflasher.exe
Step 4: type n then press enter
Step 5: type n again and press enter
Step 6 : This is when you should get to the flashing stage. Press Y and enter to everything you are prompted to. type y for yes to. This for me resulted in a successful conversion over to AT51.
Step 7: Once everything is done and it says you are safe to disconnect your phone please do so and then press and hold your power button until the phone boots up.
At this point you should have a fully working AT51 firmware!
Bare with me as I"m working on getting developer access for androidfilehost and will upload the files asap. In the meantime you can download newflasher and the firmware files yourself using Xperifirm if you don't wanna wait for me to upload.

Can you tell me the model of your xperia phone? If you can still get it into flash mode when the notification LED turns green you may still be able to recover it.

Hi, I finally managed to restore it. I have to remove all the ta files to flash it, then it booted up.
Thanks for your respond.

I have using newflasher
After using 3 time xperia companion it work normal again

Hi, I didn't find this thread until after I made an attempt at flashing the device. I followed the instructions from the link below and ended up with the device saying it's corrupted.
https://www.xperiablog.net/2018/01/...-firmware-for-xperia-xz-premium-xz1-and-more/
I tried redownloading newflasher as well as redownloading the firmware I wanted as well as a new cable and that did not help. I reflashed it with this procedure listed above and it did not help.
Xperia companion won't let me do anything because it says the device is locked even though the device was not locked and there doesn't appear to be a way to unlock it. edited to add that I did get xperia companion to repair it successfully
edit again to advise I succeeded only after doing n and enter a third time then hitting y and enter for the final flashing step and that was successful in getting it updated correctly

Would it work to unlock my phone
Thanks for the guide!
Can I ask few questions please?
First is do I need to have my bootloader unlocked? I enabled OEM unlock setting in developer settings but that is only one thing I did.
And the second one is could this flash unlock my phone?
I am in this situation where my AT51 won't work with other sims except for Vodafone. UK.
I stayed with them for 30 days, (required time frame to get your phone unlocked) requested unlock code and it has been more than 10 working days but still have not received the code.
So today I did some searching online and found the service code to check if my phone is locked to a network and to my surprise it says it's not. So I am guessing that they have limited my phone to using only their sim through some other means andnot buy locking my modem. But this is ofc just a guess.
I kept chatting with the customer support and he keeps saying wait for the code which I do not believe is going to come, they have to unlock it on their end. But I am not sure about that. I don't think they are sure either..
Basically I'll wait fem more days maybe they will unlock it but if they won't when I am thinking maybe my modem is not locked and I could unlock it by flashing different ROM?
Or do you think this won't work?
Sorry for a rambling post. Looking forward to your reply. Thanks!

Basically I'll wait fem more days maybe they will unlock it but if they won't when I am thinking maybe my modem is not locked and I could unlock it by flashing different ROM?
Or do you think this won't work?
Sorry for a rambling post. Looking forward to your reply. Thanks!

You do not need the bootloader unlocked as you are flashing official firmware.

Anyone know if you can flash a XQ-AT52 to a XQ-AT51 and then back to the XQ-AT52 firmware?
Sent from my XQ-AT52 using Tapatalk

I know this thread is a few months old at this point but I'm really struggling to flash to XQ-AT51. I've successfully flashed from XQ-AT52 Hong Kong (my original firmware) to the Taiwan version which is slightly better because of the messaging compatibility but I really want to get the US version. I have tried at least 20 times over the course of a full day and I have not been able to flash the US firmware without getting an error saying "Your device is corrupt It can't be trusted and will not boot" every time. I have repaired it back to the Hong Kong firmware (back when that was the one I had) and to the Taiwan version once I had that installed. But I have never gotten the US firmware to take without the "Device is corrupt" error.
My phone is the Sony xperia 1 mark 2 running the then default XQ-AT52 Hong Kong, and now running the default XQ-AT52 Taiwan. I've been trying to flash to XQ-AT51 US. I've been using newflasher v39 and the US firmware downloaded for xperifirm v 5.5.0.

So I was able to flash from the hong kong version to the Taiwan version and back with no issues at all. But I'm still unable to flash to the US version without the "Your device is corrupt It can't be trusted and will not boot" error that seems to happen every single time I try to install the US firmware.

Can someone make me a favor and can upload the latest ftf of Android 10 for the Xperia 1ii Single SIM?

The 1 II has downgrade protection, so as long as the firmware version of the US version isn't the same or newer than the highest version you've ever used you're gonna get the corruption error.
What you could try is flashing the newer EU version and then flashing only the older US customisation image. That's what I did for a while since US firmware was older than EU firmware, and it worked. Not sure if it'll work with Android 11.

im in the us and was looking to the 256gb version (i think its taiwan). is the hong kong or taiwan version missing anything? or is the only reason to flash to US to get better coverage with us carriers?

It's for better coverage and for VoLTE and Wi-Fi calling support. Also if you get a HK one with Android 11 you will be unable to flash the US firmware, because it is still on Android 10; and the phone has anti-rollback protection.

it arrived on 10 still, but its bugging me to update.

This isn't the case now since the US models have Android 11 too now

Can anyone confirm that this process has to be done using USB 2.x? I've read in a separate post that newflasher isn't compatible with USB 3.x, which is currently what all my computer use. Also, should I be using the newest version newflasher?
EDIT: Tried on USB 2.0 and it worked perfectly.

Question Updating s22 SD (s901u)

Hi all. I am from Singapore and I have gotten a s22 off an online platform here only to discover it is a USA set.
The csc is S901UOYN2AVE4
I am unable to get ota updates and am still stuck with a may 2022 android 12 update while checking updates shows as up to date.
I have some questions after doing a Google search.
1) will I be able to get ota updates? Does this mean I have to somehow change to csc and is this possible?
2) if it is not, do I have to update manually thru Odin patched? Given the above csc, can anyone guide me as to which firmware can I use? I see there are many different ones from different carriers like Verizon or t mobile
Thanks in advance!

were you able to find a solution? I am also facing the same issue

None so far.

Have you guys tried smartswitch?

hello! I have also researched a bit & came to this conclusion. The device was possibly under a carrier (such as ATT or Verizon) from the US. Although it's unlocked and you can use any sim card but you won't receive any updates unless you use the sim card of that particular carrier. You can install the latest firmware using ODIN tool yourself by downloading firmware based on CSC region code. You can youtube to find the specific CSC region of your phone. Please let me know if you find any other solution. & also please let me know what 'service provider software version' is on your device. you can find it at About phone>Software Information

I have managed to flash it with the right software and get it to update ota. To test this I flashed a older android 12 firmware and it manages to update to android 13 ota.
Follow the steps in this thread closely and you will be good. Use the unlocked u1 version firmware.

Just to confirm one thing, My CSC is S901UOYN2AVE4 and AP/CP/BASEBAND is S901USQU2AVE4. Csc is basically same as you.
But my service provider software version is SAOMC_SM_S901U_OYN_GCF_12_0002
GCF/GCF, GCF/XAA.
Will it alright to flash u1 unlocked firmware to the device? This software version shouldn't be an issue right?
