Hey guys,
I got a problem.
Bought a second hand z2 today and it sayt it got a update 17.1.2.A.0.314
When I dontload it it sayt cant verify,same with pc companion,but then it says this phone has custom software or something.
I suspect,unlocked bootloader,but when I try to relock bootloader with flash tool it sayt,this phone can not be unloaded officialy?
Someone know how I can fix this?
and is there a way how to check if bootloader is unlocked,like Samsung when u boot with power button and volume up.
Thnx
Go to your dialer and enter *#*#7378423#*#*. Then go to Service Info -> Configuration. What is indicated under Rooting status?
If it says "Bootloader unlock allowed - Yes", this means that your bootloader is still locked but can be unlocked.
If it says "Bootloader Unlocked - Yes", then it means that your bootloader is already unlocked.
If it says "Bootloader unlock allowed - No", then it means your bootloader can never be unlocked.
If your bootloader is indeed unlocked and you want to flash stock firmware, you cannot use PC Companion. You need to use Sony Flash Tool instead.
I faced the same problem. If you have modified any system files (like build.prop) or removed/uninstalled any system apps, then it will error out with the "can't verify".
Just revert all changes you made, re-install and system apk u removed, and try again.
Hello everyone,
I tried to reset my XT1068 phone from Motorola to the original system from Cyanogen mod. When I got the phone, there was already Cyanogen mod installed, but I didn't bought it myself.
After some tries I finally used a Version 5 (?) Android image. All the steps with mfastboot (v2) succeeded - also locking the bootloader.
However after restarting the phone I got ( and still get ) "failed to validate system image. ( fastboot reason: Fall-through from normal boot mode )"
and also "Device is LOCKED".
Why did this happen? Did I flash the wrong image? How can I find the one which fits to my system and the current bootloader?
And the most important part: How can I restore the system to a working state?
I don't want to unlock it using a code from motorola, because if I need support, it would be probably bad, if I voided the warrenty this way.
Is there (any) another solution without requesting a unlock code from motorola or without unlocking the phone again?
Any advice would be highly appreciated.
Thank you very much.
Kind regards
Hi guys, so I seem to have scewed up my phone quite badly. I tried to deodex running the new nougat firmware (with drm-fix and ric-off) by flashing a zip in the nougat firmware thread. Somehow I ended up with not being able to fastboot anymore.
I found out that my bootloader seems to be locked again. Thus I am not able to approach the fastboot mode, but failed to do any flash, as it says [FAILED (remote: not allowed)].
I checked the service menu and found the [Bootloader unlock allowed:no] and [Remote Lock State: Locked] after reflashing the nougat firmware.
So I wanted to unlock the device, how ever I ended up with flashing back to Lollipop and the device boots and then power off after a few seconds of use.
Could this due to "remote lock state: not allowed"?
Try relocking via flashtool?
So. Tried to lock and relock via flashtool. Checked drivers which are working fine.
I was trying to relock and then unlock again using flashtool after updating to .305 Marshmallow firmware . However this does nothing to the bootloader states. The weird thing is that there are no errors showing up in flashtool when unlocking/relocking. I can't even unlock via OEM because when I tick OEM unlock in the developer options this doesn't do any change (Rooting status: Bootloader unlock allowed : No, Remote Lock State: Locked). My DRM keys are gone as well. However I do have a TA Backup but can't restore because after downgrading to lollipop the device shuts down after 30 seconds.
I'm really annoyed because I bought the device with an locked bootloader (without carrier costumizations) and unlocked it via OEM unlock then updated to . Is there any chance to unlock the device again? Restore TA? Any recommendations what I could have done wrong would be helpful.

[solved ] Bootloader is now sucessfully relocked andBootloader states are back to [Bootloader unlock allowed: Yes] and [Remote Lock State: UnLocked].
I need to mention that I bought a phone without carrier lock with [Bootloader unlock allowed: Yes].
So, for anyone who is interested or might face the issue in the future, here's what I did.
You will need your backed up TA-Partition-Image to restore via iovyroot:
1. Downgrade to Lollipop (32.0.A.6.200 / R2B (STOREFRONT GENERIC)) using Flashtool .
->Therfore select/tick everything in the wipe section when selecting the Lollipop-tft
2. Unmount your SIM, reboot the device
3. Skip everything on the welcome/configuration screen as fast as you can to get beyond the Android configuration screen
(skip wif config, Google-Account setup, untick myXperia services! etc.)
The phone might power off only after a few seconds because of the downgrade. So be fast!!!
4. Once you end up on the home screen, unlock developer options, and activate ADB debugging, grant ADB access (check via cmd: fastboot devices)
again: be fast! --> Don't worry if the phone shuts down again. Just reboot if you were not fast enough.
5. Download iovy.root ( iovy.root. Place TA-backup.img in the iovyroot-folder.
Then I modified "tarestore. bat" to save some time regarding the shutdowns. I used notepad++:
...
set response=
set /p response=Type "y" if you want to restore this file:
if "%response%" == "y" (
echo Starting restore
echo.
adb push "root/iovyroot" "/data/local/tmp/iovyroot" > NUL 2> NUL
adb push "root/restore.sh" "/data/local/tmp/restore.sh" > NUL 2> NUL
...
5. Run CMD as admin. CD to Iovyroot folder.
Restore using tarestore.bat (tarestore.bat TA-2016-xxx.img) as soon as your device boots up to home screen and seems to be connected as ADB device.
( I checked this by running the windows device manager simultaniously)
Wait to end the process.
-->When the restore was sucessfull, the device shouldn't shutdown again.
6. Reboot. Your bootloader is now locked again (but able to unlock via OEM unlock). DRM keys/functionality is restored.
I have the same problem (after i had nougat working incl drm fix and root, also the deodex, tried flashing lower ftf files too when i got this problem, noticed the rebooting, which it does not do at 305 kernel or higher..
I would have hope in your solution, if I could find my ta backups (i have from some other phones, this one, may have been on a crashed laptop, already searched through old hdds)
Could this be because of fastboot flash recovery twrp.img (cause that is something i never done before on the z5c.)
If anyone has a solution other than restoring the ta partition, i would like to know. Because i am very uncertain that i can find those files again...
Same case here z5c unlocked since +/- 1 year and I don't have any TAbackup too
I will try to downgrade to .200 But with bootloader unlock allowed : no ... I don't have much hope
edit : no chance, I tried .200 but without tabackup, I can't do nothing
When I faced this problem I noticed it happened because I wiped TA options with Flashtool. Never do that if you don't want to lose TA partition and all other things connected to it. I could fix it only by flashing TA backup even though I hadn't the timing issue zegovernator had for flashing back TA.
I actually wonder why Flashtool allows to wipe these critical partitions/options

I'm sorry for you. I would recommend updating back to MM since LP gives you immediate shut downs when recognising that your TA is lost/wiped. It's sometime a pain in the ass that stuff gets posted before testing. Nonetheless, you could still try to send in your device back to Sony Costumer Service if you are under warranty (after flashing .200, say that it is "broken" and keeps crashing). However, I would not trust on them sending you a new device.

I sorry to say that, but if you lost your TA-backup or didn't even back it up before unlocking the bootloader there is no hope at the moment. You simply can't fastboot because of the Remote State: Locked. It keeps you from accessing the bootloader.
I found my iovyroot TA-backup.img file, I did have a .200 storefront ftf and tried it on that one, which was very anoying as it wants to start a demo , i found an other .200 ftf online which I tried, and the iovyroot seems to work, at that time no reboot, in service menu, the drm keys now seem fine there, Bootloader unlock allowed : No, Remote Lock State: unLocked , fastboot boot or oem unlock still seemed not working well i think that is what it said, (flashtool unlock always seems to, i did try) now i flash a new ftf and try my luck there with the unlock status.
flashing ftf 5.11 flashtool says
03/005/2017 05:05:49 - INFO - Loader : S1_Root_f936 - Version : MSM8994_50 / Boot version : S1_Boot_MSM8994_LA1.2_119 / Bootloader status : ROOTED
And now in 5.11 it also says bootloader unlocked : Yes Lost my drm again
So I am back in flashing and rooting (with drmfix etc) Android 7 again Thanks for sharing this solution!!
So you confirm that TA backup is the only solution to solve the "unlock allowed" bad state, don't you?
This is good for other people because when I faced the problem I was really scared to have messed up my phone!!!
i want to confirm the solution here
i had the same problem and the only way back of it was to downgrade to Lollipop and restore the TA-Partition
i dont think there is a solution if you did not backup your TA and have an image of it.
Yes, the TA restore is the only known solution, and I am glad Zegovernator shared his solution here
So basicaly I was being lazy and in a rush. I had done something like this before on much older phone(s) with no issues...
I backed up my working LG G5 in TWRP all partitions. I brought exactly the same model for my wife and wanted to restore my backup to that phone (I have made many customisations on my rom and didnt want to have to manually do it all again for her)
However after unlocking the bootloader, flashing TWRP and installing new base rom (all went fine) I then went to restore my old backup onto this new phone, stupidly I ticked all partitions to restore. I have a feeling that I should have only done the larger partitions. Once I rebooted I got the "cant be trusted" message, I reflashed in UPPERCUT but then the phone booted and then had secureboot enabled. I hit the wrong password (as there was none) 30 times which then forced a format. Now the phone boots fine and works 100% BUT...BUT....
I now can no longer unlock the bootloader as I think its trying to use MY phones bootloader (as its unlock.img says its the wrong one, I have tried both MY phones original unlock.img and my wifes new phones unlock.img but both dont work) I cannot relock the bootloader as it says its already locked... this also now means that through LG official software I cannot recover the phone. Only UPPERCUT can see the phone. I can get to download mode and fastboot.
Also the phones IMEI now says 0, this worried me however her SIM card is working 100% fine (I guess that the IMEI
is cached somewhere, but im worried that if I use some cleaning tools it may scrub it and then she will have no network access)
So basicaly if her phone starts to play up (or I want to upgrade it to Oreo / Lineage at a later date) can anyone offer me advice on how to...
A: Fix / Restore the bootloader (I dont mean recovery) Im confused as to if this is stored on a chip or can be reflashed from the kdz firmware images.
B: Resore the IMEI (I have it written down) incase we get any network issues in the future. Can it be resored or regenerated without some fancy hardware, ie only through software.
C: I dont have Root or TWRP access it seems, any way of Getting Magisk or Super SU on a phone without bootloader unlock, root access or TWRP?
I have had many years experience and never bricked a phone but almost did this time.
I decided to post a solution here, because it was one of the first Google results when I was looking for some help.
Long story short, I did exactly same mistake of restoring all partitions, including the EFS, between two same LG devices. Turns out it messes with IMEI, which is a big no no and phone locks. Now you can't unlock the device again, because there is no IMEI to use in unlocking. Also no flashing or erasing anymore, because it just fails.
So the IMEI needs to be restored first.
My phone was in a bootloop constantly showing the "cant be trusted" message, but I managed to fix that using LGUP. Apparently not all partitions are locked, because trying to flash the same system with LGUP fixed the bootloop, but failed to flash clean system and the data that TWRP flashed was still there. Trying to restore system to factory settings also fails, but it doesn't matter.
Fortunately I was able boot the system, which made fixing it easier than you'd expect:
1. Fixing the IMEI from booted system (no root or unlocking needed):
- Access the hidden menu on your device by dialing a proper number. For LG G5 H850 it is *#546368#*#850#
Where 850 in the last part is your phone model. The number will vary for different models.
- Go to SVC Menu -> CRCWIZARD Test
- Switch tab to Auto MID
- Here you can enter your new IMEI and WiFi and BT MAC addresses, or you can just generate it.
You can also use the generate option for all values and then manually change only the IMEI for the original one.
- Press MID Write button and reboot your device.
- That's it. IMEI issue should be fixed now.
2. Now that you restored your original IMEI, you can again unlock your device using the same unlock.bin file that you used to unlock bootloader the first time.
Voila. From now on the device is again unlocked and you can just go back to flashing whatever you need.
Hello everybody.
my question is a little bit noobish, is losing a phone with locked bootloader have any security benefits?
like if it's lost or stolen can the thief access my data ?? can he use the phone after formatting it ??
i really need to know it, and my English is not very good as i tried to search for any updated topic about this matter and i couldn't find such thing
On locked bootloader, he can't access your data as your storage is encrypted and any attempt to unlock the bootloader will wipe the storage out. Even if he does some kind of a factory reset, he will still come to the point where he needs a password to unlock the phone after a reset. So no, he can't really use the phone if the bootloader is locked.

With locked bootloader, the thief will not be able to use the phone at all if you have it in secure lock screen.
With unlocked bootloader if you are encrypted (not flashing fde) he will be able to use the phone but will never have access to your data.
With unlocked bootloader and unencrypted (by flashing fde) he will be able to use the phone AND have access to your data.
Thanks guys very helpful, I needed to know the risks... Many thanks [emoji4]

Eventually you can unlock the phone, without using FDE, and backup/flash/restore with an USB-OTG cable and a USB drive, so your data will be encrypted but you still can "play" with your phone. That's what I did.
