[Q] Please help savage my Z1 - Xperia Z1 Q&A, Help & Troubleshooting

So the other day I confirmed for an OTA update for my Z1. Little did I know, 3 seconds and an auto shut down later, I would end up with my Z1 being stuck in a bootloop with no access to recovery mode.
I really need help on getting my Z1's internal memory (photos, notes, contacts) extracted. I tried a few of the local repair shops and they said that the data inside is corrupted.
I've try ADB but it says "permission denied" whenever I try getting in the storage>sdcard. Probably due to me putting a swipe pattern lock screen on it.
So if there's any hope at all, I'm willing to even disassemble it if that could even help.
I've not rooted it but I do believe the bootloader is unlocked.
- I should also mention I'm a real amateur at this stuff so please be very patient and specific with the instructions. Thanks!

Try using this guide: http://www.ibtimes.co.uk/how-instal...z3-z2-devices-via-xperifirm-flashtool-1492498
it's for updating your os with flash tool just use an ftf file for z1. And in the final stage of the update untick the 3 wipe options and this should save your data.

i'm not totally sure this will work, depends on how much your memory is ruined. If it was just an installation of your os error this should reinstall an updated os without erasing data. first try other methods for saving your data and if you won't find any, try this one

btw, in the picture i posted i didnt untick those 3 wipe options, don't forget to untick them else you'll wipe your memory!!!

I tried with all 3 available firmware (SG) but still not able to boot up the phone normally, nor was I able to access the memory through adb. Any other thoughts on that?

1. try flash ftf again, unstick applog and data, stick on cache ( wipe cache). try several times maybe it will bootup.
2. you sure your bootloader is unlocked ?
use flashtool to check your bootloader status, if it really unlocked just flash a custom kernel have build in recovery to save your data.
if it is locked bootloader, you can unlock via flashtool, it wont wipe you data like fastboot unlock, and flash kernel but you will lose your sony function forever if you dont have any TA backup before. you should consider to choose your data or sony function.

Are you sure your bootloader is unlocked?
Dude, Are you sure that your bootloader is unlocked?
1st confirm that and accordingly there are ways by which you can recover your data.
Guys here have already recommended methods by which you can get your data back. I suggest read through general an Q&A forums. Read thread for soft bricking. Do not panic and carefully follow the instructions. You should get your data back.
similar case has happened with me few times and I was sucessfully able to get my data back.. so dont worry..

[Q] Forgotten pattern lock

Hey, I wanted to ask that how can I remove the pattern lock on my friend's xperia z she forgot her pattern after changing it and she don't even remember her gmail id & password. I know most probably its going to be hard reset but is it compulsory to hard reset the phone with pc companion or is there another way from the phone itself like recovery mode? The phone is not rooted.
And how to get the data back after hard rest?
Thanks.

Hi,

Hey,
i have a similar problem. A friend of mine, who is not the smartest with technical devices, forgot his Lock Pattern and his gmail adress.
I would Hard Reset ,but he stored all his Phone Contacts and Pictures of the last year exclusively on the Phone.
The Phone is a Xperia Z C6603 in complety Stock conditions (Bootloader locked, No Root).
ADB Debugging is off.Wlan is off. Mobile data connections are activated.
Is there any possibility to bypass the lock pattern without hardreset and in best case without unlocking the bootloader/voiding the warranty?
I thought about something like:
Boot a costum recovery via fastboot:
fastboot boot recovery.img
To get a recovery with enabled adb or a filemanager to delete or extract gesture.key
1.Is this possible under these circumstances?
2.Would it otherwise be possible to extract the data form the phone?
The Phone contacts would be more important.The Pictures would be nice to have
Many thanks in advance.

You can't use fastboot until you unlock your phone bootloader (/your friend's, whatever).
And even if you are concerned about doing this, you will need to make a TA backup, unless you'll erase all your DRM keys during unlock proccess, in the result you'll not be able to re-lock bootloader with DRM keys. They will be forever gone. To avoid this, you have to backup TA partition. And the most sadly part is that to do that, you need to enable USB debugging Unfortunately, to do this either, you need to unlock your screen D
Tell your friend that he has only 2 choises:
1. Unlock bootloader and then flash system.img (but you'll erase your DRM keys, it will result in Bravia Engine, Walkman and other functions not working and/or etc.)
2. Completely remove all data and restore phone (Hard-Reset, as you already said, you can perform this action by using PC Comapion).
However, I don't know any other alternative way's.

This is Xperia Z forum. Check your phone section to find correct solution.
Hey LaurynasVP,
thank you very much for your fast answer.
Just to not talk at cross-purposes:
When you say I can't use fastboot with looked Bootloader did you mean only the fastboot flash recovery.img command (not fastbood boot recovery.img ) or fastboot at all.
If I can't use fastboot at all ,choosing Select Kernel to Hotboot in Flashtool wouldn't work neither?

This device doesn't have a recovery partition, so using fastboot to flash a recovery isn't possible at all.
Most fastboot commands aren't allowed until you unlock the bootloader. The /data partition is wiped when unlocking the bootloader, so that obviously isn't an option for you, being that you want to recover data from the device. I also believe that hotbooting a boot.img or recovery.img is not possible on this device either.
Your friend should try to remember/recover their Google account credentials as that is the only way they will get their data back.

Unbrick P9 Eva-L19 or where to get logic board

Hi guys
I've mistakenly (I guess) placed an update.zip in dload folder from the internal memory.
When I booted it with key combo to force update from there, it reaches 5% and then I get an error regarding it does not correspond with original version
When I boot it I have 2 options
- Huawei erecovery, where I get it failed through WiFi
- Wipe data or factory reset, which cannot be done
After this I tried getting original ROMs, placed them in dload folder from sdcard, and I get same error as before. So I think it is not taking into consideration the files from there and I think it is still trying to update from internal memory
It had version B605C135
Then it went to b605c135custD003 or 007 and the problems started from there
My questions would be
Is there any procedure to unbrick and make it work again? ... or...
I was told in repair stores to replace the logic main board, but I cannot find a place to buy it. Does anyone know where I could find this spare part?
Thanks a lot in advance [emoji847]

Try to recover with dload folder with UPDATE.APP (in update.zip from differrent FULLOTA versions) insided, by press and hold: Vol Up + Vol Down + Power buttons.
I have an EVA-L19C636 and it's worked and recovered with B320 version only.
Oh I see. The bootloader's locked. Just curious though, why is wiping and restoring to factory data not working?

I'm not sure what that means, but can you post screenshots of your recovery? You should be able to access that by pressing Vol+ and Power at the same time.
At this point, I think what you should see are options to wipe and all. Can you also post pictures on what happens when you select either? And have you tried unlocking the bootloader through ADB?
The goal I have in mind at this point is for the device to be able to boot so that you can access the Settings app
I've finally paid DC Phoenix flash software license
Tried EVA-L19_C432B360_Firmware_Austria_Poland_Hungary_Bulgaria_Czech_Republic_Nonspecific.APP
And voila, it unlocked bootloader, unlocked frp, did everything and unbricked the phone
Now have to test network bands, etc.
But this is an advance

unlock the bootloader (Unofficial free way)

While searching for a way to unlock the bootloader i found a way
​Hello. Instructions for unlocking the bootloader.
-------------- Responsibility for your bricks I do not take over. Everyone does at their own peril and risk .--------------
Downloa ( Google)
1) Install the driver for the phone (in the header);
2) Install a special driver, find it in the Unlock_BootLoader \ Driver for Winwos \ DriverSetup.exe folder;
3) It is necessary to unwind the phone, remove the cover;
4) It is necessary to disconnect the battery;
5) It is necessary to close the contacts (Photo);
6) Connect the phone to the PC;
7) Open the program Unlock_BootLoader.exe, there is a menu at the top, the item: "Operations> Settings> You need to select the Unlock_BootLoader.xml file"
8) After selecting the Unlock_BootLoader.xml file, click "Operations" again and click Start. Or press the green play button.
9) Done. Now you have TWRP_Mod installed in the Recovery section.
Additionally
The method works both with a locked bootloader and an unlocked bootloader. The only difference is that how to use this program at the moment when the bootloader is unlocked, then you do not need to disassemble the phone and put it into TEST POINT mode.
If the bootloader loader, then the program flashes TWRP_Mod.img to the Recovery section. After flashing, the phone will automatically reboot and the bootloader will remain locked. But TWRP_Mod.img will work. If you need a full unlocking of the bootloader, then you need to prepare several other files. There was no time for that. I made the method only for flashing custom recovery.
In the video, my bootloader is unlocked. I had a chance to block the bootloader and delete all data, so I made a video with the unlocked bootloader.
With a locked bootloader, exactly the same thing, the only difference is that you will need to switch the phone to TEST POINT mode​Youtube video
All thanks Goes for SergeySan27 for his work...
this made for 4pda and i am just sharing his work
This is 100% not working. Pls dont waste your effort
Wow
Specific what version of Pie do you have on Honor Play?
can u also tell if we have a method by which we can unlock our bootloader. If its possible using this technique then we can have development for our device. More people will be available to use the roms.
Excuse me, sir. Where is the TEST POINT?

I know lot of people already know but for everyone else's clarification Test Point or EDL Mode requires physically opening the phone and shorting 2 electric points together something like the following video.
https://www.youtube.com/watch?v=W8salW6m-z8
I do not know exactly where those 2 point are on honor play.
But one good thing is opening honor play is comparatively easy as it does not require heating the screen with some heatgun. There are 2 special screws and then the screen is clasped.

the IDT started to flash the image and I got the successful PASS green message in the end.
The bootloader is temporary unlocked in testpoint mode
however, even if I have kept the VOL UP button pressed and removed the usb cable to reboot directly in the recovery mode (to prevent the overwrite with the default eRecovery) it still brings me to the default eRecovery menu.
I have even tried to flash TWRP manually in fastboot (using the tespoint mode to temporary unlock the bootloader) and I got the img file sent and written.
However, it still brings me to the default eRecovery.
Do I do something wrong or miss something? becase flashing of any image is successful but I can't get anything changed on the phone (just getting OKAY or success messages on the pc)
For everyone here trying by opening up the phone, make sure you DON'T touch any other 2 points or your motherboard will short-circuit and become unusable.

Did you try going to recovery through command line?
Code:
fastboot reboot recovery
(or reboot-recovery)

Why would people have to take this tedious route to unlock their Huawei or Honor smartphones? Huawei as a company should listen and release bootloader to those who wish to unlock their system. They can put in place an agreement to be accepted by those who want to unlock their phones and expected no warranty after doing so. This is very simple to do.
Can someone confirm test point connectors on the play please?
Doesn't look too difficult imho.

Mi5 softbricked after removing default launcher. File recovery possible?

Hi,
I have removed default-launcher by accident, then i tried to install Mi Launcher from store, and everything was meh. After rebooting my phone, it stuck at recovery menu. After that, i updated the firmware using Mi Assistant, and nothing changed. I just want to backup my photos and files. I wasn't able to get any success with fastboot and adb either. Bootloader is locked, device is not rooted. Could you please help me?
Hi, so are you able to boot into recovery? In recovery, your computer could recognize the phone (in TWRP it does).

Yes it boots into stock recovery menu. I don't have a custom recovery installed, and i cannot install either because phone's bootloader is locked (which will wipe the all data including my images etc. if i do that). My USB-Debugging was enabled while the phone was on, but right now, I am unable performa any adb commands.

Ok, I see two possible solutions:
1. When you boot to stock recovery and connect your phone via USB, does it open on your PC as a drive? Could you extract files this way?
2. Are you able to install updates via stock recovery? (I had to ask, I didn't use stock recovery for years) If yes, you could theoretically flash an original Xiaomi ROM. Please see this article: https://bit.ly/39wTVmj

1. Yes it connects to pc but not as a media or drive, in sideload mode in adb. There is no way that i can make it force use that.
2. I am not able to install updates via stock recovery. It doesn't have option nor file explorer like the one that you posted. There are 3 options:

The problem with MiAssistant is that it's no longer continued to be developed in English. So the latest version they provide on their website is not even recognising the device. However after some search I found some unofficial translations of Chinese Beta versions of this software. I have found v3.0.3301.134 and v4.0 versions. v4 crashed during installing stock rom (recovery.exe stopped working), however I was able to "Update" to the stock rom with v3 version using this guide.
After that nothing happened. It installed till 100%, and keeps rebooting. I am not even sure if it's installed correctly anymore. All i can think of is wiping cache, but that doesn't seem possible either.

1. Yes it connects to pc but not as a media or drive, in sideload mode in adb. There is no way that i can make it force use that.
2. I am not able to install updates via stock recovery. It doesn't have option nor file explorer like the one that you posted. There are 3 options:
- Reboot (Regular reboot)
- Wipe (I would like to wipe cache partition but it doesn't give any information. The info on the net suggests that it factory resets the phone. So my data/photos will be gone)

In this case, I don't know. Maybe someone else will find solution.
I don't know if my solution will work or not, just try it if you don't have any other option.
Try it at your own risk, IT MIGHT HARD BRICK YOUR DEVICE.
1: Download Miracle Box crack.
2: Install Mi 5 and Mi 5's fastboot driver.
3: Open Miracle Box and follow the screenshot I uploaded.
https://2.pik.vn/2020c57cbe0d-5f8e-4fae-b73b-7332da16e2b2.png
4: Tap the "Start button" and wait for miracle. Reboot to your phone, if it shows "unlocked" then it means the bootloader is unlocked, install TWRP. Launch TWRP then connect your phone to the PC and get the files back.

[SOLVED] Can't using LGUP now. bootloop with 9008 mode. (V409N)

Hello!
I unlocked the bootloader first.
However, after rebooting, the twrp failed to flash.
and I got a message to re-lock the bootloader.
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
After that, I checked several guides and tried.
but now, never can't boot and can't use LGUP.
Any method to restore stock rom via 9008 mode? please help.
PS :
I think download mode is also broken.
Please let me know if there's any way to recover the download mode.

I'd suggest looking at this thread. Also, the screen telling you the bootloader is unlocked is normal, when you have a device that has it unlocked, you *always* see it when you boot up.
cheers

Very thank you!
but Unfortunately, it didn't work for me.
I forgot what i did, but maybe I modified xbl_a, xbl_b, etc.
and try below method it didn't work, too.
I've touched too many things....
I'd like to know if there's a way to force the use of LG Flash Tool or something like that.

Follow this post. (Don't speak Spanish so have no idea what the above video is doing, can't help there).
Essentially, when you flash an image to a partition it doesn't belong in, you run the risk of overwriting into nearby partitions (because image is bigger than partition size). If you do that, then the only solution is what's in the post above. It basically restores the entire device using qfil. Because when you start overwriting partitions (and possibly the partition table), there's no way of knowing what is messed up and what isn't.
cheers

good that it worked. Follow this link and in the folder find boot_20n_magisk.img and use it (assuming you're on kor 20n), use qfil to flash it to boot_a and b.
It has both magisk and twrp in it. Remember, after flashing it in qfil (save original first of course), you need to hold vol - and pwr for a few seconds (until u hear windows chime meaning disconnect), to exit qfil.
But! and this is important, we don't want the device to boot, we want to go directly to recovery. So keep both buttons pressed but when LG logo appears, release pwr and then re-apply it, which then goes to recovery.
in recovery, u have to format data, then reboot recovery and flash dm_verity.
cheers

Thank you very much for your follow-up.
I succeeded in entering the twrp.
But I got screen asking password, there's default password or something?

There's no password, you just cancel out of that but be sure to do the 'swipe' to make it modifiable. The key after that is to format data, then reboot recovery and flash dm_verity, then encryption won't exist and no longer asked for pw.
cheers

OK, Thank you!!
I followed the guide below and no more password message!!
How to use decrypted stock by @Xsavi : https://forum.xda-developers.com/lg-v40/how-to/guide-twrp-data-access-stock-t3970149
I think everything's finally settled.
I'll try my best to enjoy the v40 now.
Thank you so much for your help.
many many thank you!!!!!!!
