XZ1c bootloop after low storage, tried flashing, keeps on bootlooping

Hi,
been breaking my head about this strange problem for days now.:crying:
Device: G8441
State of device before incident: Bootloader locked, Developer Options off, all stock/Playstore. Aka off the shelf.
What happened: Went into bootloop (black Sony on white background) after device ran short of internal storage while attempting to install an app from the Playstore (it went into pending and gave me a storage warning). Upon then the device became laggy, so I rebooted. Phone never came back to life. I took many photos that day, and upon getting a storage warning earlier I had changed the camera save location to SD. The battery was at about 30%.
When it happened: 17/02/2019, at that point I am pretty sure I was up-to-date with OTA updates.
With the bootlooping phone I am able to connect Flashmode (green LED) and Fastboot mode (blue LED).
I could get the following info from Fastboot:

What has been done so far: By now I have tried to flash almost a dozen different firmware FTF's obtained from Xperifirm, first trying Flashtool by @Androxyde and later Newflasher by @munjeni. I always excluded userdata.sin and most of the .ta files. The flashes seem to work fine as they finish normally and throw no error. But there has been never been a change to the bootloop whatsoever at all at any point.
Only in Flashtool I get some blue warnings about packages excluded from flash.
Strange: Fastboot keeps reading the baseband version as "(bootloader) version-baseband:1307-7511_47.2.A.6.30". However, Xperia Companion identifies it as "47.2.A.8.24-R3C".
It doesn't seem to matter which firmware version I try to flash, fastboot will always identify it as "47.2.A.6.30".
Only with the bootloader version I identified changes between "version-bootloader:1306-5035_X_Boot_MSM8998_LA2.0_P_107" and "(bootloader) version-bootloader:1306-5035_X_Boot_MSM8998_LA1.1_O_77".
I noticed that when plugged into the charger, the phone will attempt boot and go into bootloop. It won't show the Charging screen.
Goal: Get it to boot Android again, into any kind of firmware, to save the tons of non-backuped photos, and only then do a factory reset/Xperia Software Repair...
Question: What else can I try? Is the problem that my internal storage is full, and it is blocking the OS from booting, thus I need to free up space? Is it possible to flash a userdata.sin that only wipes storage partially? Or maybe a partition problem? Is it possible to flash a stock ROM that boots into Safe Mode directly, then stuff could be deleted slectively?
Am hoping to find advise from some experienced devs here.

You said you deleted most of the ta files. I thought you should delete all of them. Also delete persist.sin file. Other than that, I would do a clean wipe. Sorry about your files.

Thanks a lot for your reply.
Yes, during the first few flash attempts I excluded all .ta files. After reading more in the forum I understood there are different opinions about their potential danger, especially since my device's bootloader is locked and Dev Options are off. Then I started to include those less dangerous .ta's during the flashs, like 'reset-non-secure-adb.ta' or the one in the boot folder, 'Lilac_XBootConfig_MiscTA.ta'.
I thought more about the moment the bootloop started and think maybe the Sony Power Saving mode got activated, since the battery was near 30%. Mmhhh
Yes, I am considering a clean software repair with Xperia Companion, too. I still want to try everything to get those photos. Thinking Software Repair -> Bootloader Unlock -> Root -> Internal Storage Raw Image -> Mount it -> Scan . . . damn
Thank you.

I have a similar problem. I bought a new phone because xz1c had memory issues. I was removing Facebook on Google play to save up space to install Samsung Switch. The device went into that bootloop you mentioned. However, I am not a proficient user like you, I can't perform any of the things you've mentioned. But I do recognize the blue and green flashes before the Sony sign. Then comes the black maintenance triangle, then android logo and reboot. A few times I have seen it pass on to xperia logo, but failed to boot every time.
The only goal is to get the device back on so I can transfer phonebook and messages because I don't have any backups. And they are important for me.
Any solutions?

Upgrade to Android 10 with my Mi A2 resulted on a bootloop.

Hello everyone. I have a Mi A2. There's been like a week ago or more that popped out on my phone an update to Android 10. I downloaded it, and when i pressed to reboot the system, the phone tried to boot but failed. When i put the phone to charge, it starts to bootloop. When it's not charging, it tries to boot one time and then turns off. I can get to Fastboot thru volume down + power buttons, but it gets stuck on the rabbit screen fixing the android robot. I've downloaded ADB, XiaomiFlash, the ROMs, all the stuff to recover or format the system. All commands with fastboot give me errors. I can't change the partition to "b" 'cause it says that it is in "lock state". When i try to unlock it (fastboot flashing unlock_critical), it says that Flashing Unlock it's not allowed. I've been like close to 6 hours on the pc today trying to fix this **** and tried almost everything. Can anyone help me? I saw some things on YouTube but it would require me to open the phone, but i don't have the tools, neither can buy them ('cause COVID-19). I'm not feeling tempted to send the phone to someone to fix it. Neither wan't to buy a new one. It was a system update, for christ sakes.

You could read this forum and get answers - bootloops are often after OTA, especially with OTA to still buggy Android Q.
So, summarizing answers you could find here:
1. AndroidOne for MiA2 uses A/B partitioning scheme, developed specifically to automatically return to previously installed Android version (in X slot) after OTA update to Y slot fails.
So You are to continue rebooting (bootlooping) with external power ON, until phone reboots to opposite slot. People wrote that extracting SIM helps to minimize number of reboots.
2. Switching slots via fastboot command, as well as flashing, is blocked until phone is fully unlocked (has unlocked boot and critical partitions). Only information command work, e.g. "fastboot getvar {...}".
3. Unlock is enabled only if phone has "OEM unlock" allowed in developers' options.
4. Without unlock, and being unable (or not patient enough) to reboot to previous slot, the only method left is disassembling phone and using TestPoint/Edl method.
Having written this, I expect that you will search for used keywords in these forums and the net, - and thus will do your homework yourself, - or bring phone to service.

There is a way that it seems to work holding the +/- button and power at the same time, it can make the phone change slots

First of all, thanks for answering so quickly. I was so stressed out after spending + than 6 hours at night, i know nothing about these stuff, so i had to start from 0.
1. I didn't knew that the looping was the phone trying to get back to the previous stable system. Right now, i've put it with external power on and took out the SIM. Will let there for a while.
2. Later i'll give you the information about "getvar", but i've tried that already yesterday, it was getting me some kind of unknown error.
3. Yes, almost all videos on YouTube guide people thru this part, but since i can't access developer's option cause the phone won't boot, it's impossible for me to do that.
4. I will continue searching. Also will try to buy a tool to fix it myself.

Thanks for aswering. I've already tried that, no response. :crying:

your phone will only be with test point, when it works again leave the bootloader option enabled, so you can make the phone work again when there is a problem

Hello everyone. I've got an update. I've plugged the phone in fastboot mode without SIM (idk if that's the cause) and manage to get a result on getvar all.

Also, i've managed to (idk how exactly either, i was pressing the buttons) freeze the androidone screen while bootloop.

Hey everyone! I've managed to fix my phone thru test point. Like in this video: https://www.youtube.com/watch?v=5JaSIKoDDGg&t=6s
For anyone trying to do this, if u are getting errors on XiaomiFlash, move the ROM folder to C:/ and rename it to "ROM".
Also, the problematic update was the november one, that caused the bootloop. I'll probably won't be able to update my phone anymore right?
Thanks to everyone!

Regular OTA updates still possible
Hey, went through something similar back in early 2019. Of course you can update your phone. Allow unlocking and debugging and then wait if they pull and fix the OTA update and try again and if that does not happen wait till they release a stable fastboot ROM image that is already updated past the current dodgy update and manually update your phone and then continue with regular OTA updates.
good luck!

Help me

I am in need of help with my xiaomi mi a2 I am not able to make a full flash by miflash because the phone goes out of fastboot mode and turns on alone. I'm also having a problem using the Cellphone, if I try to turn on the flashlight or any other function to slide the screen down with the screen locked or using the flashlight to flash and the Cellphone turns off and crashes, I'm also having problems when switching between apps because when I change it just closes. can someone help me get my cell phone back to normal?

your explanation makes it difficult to help you and doesn't explain the problem properly & it is not up to others to fix your phone ... but if you're lucky you might get some advice how to ??*??* ..also helps saying please...
1. what version of android ?
2. stock or custom?
3. bootloader locked or unlocked?
4. rooted or unrooted?
5. which mods and launchers are you using ?
6. which version of miflash are you using ?
7. which version of stock are you using ?
* first of all
-uninstall fastboot and miflash ..reboot ..install latest version of both AND QUALCOMM 9008 DRIVERS
- check that bootloader is unlocked and oem unlock is toggled
- connect your phone and enable adb debug
- download latest stock rom fastboot
- unzip to /C of pc
- run cmd window from adb folder
adb devices
adb reboot bootloader
-run cmd from fastboot
fastboot devices
fastboot getvar all
*paste answer here
*ARB must be less than 2
*unlock critical must be unlocked
*bootloader must be unlocked
*if not run :
fastboot oem unlock
fastboot flashing unlock_critical
*now enter edl
*prepare miflash
*select extracted stock rom & select "clear all"
fastboot oem edl
*screen will go black
*refresh miflash
*flash

Mi A2 bootloop: something missing?
Hi, I am trying to revive a Mi A2 from a bootloop state (the coloured thin stripe circling endlessly through the middle of the white screen). Fastboot and Recovery are accessible and the bootloader shows as "unlocked". I bought the phone in this state, hoping to make it work.
Following your instructions above, I used MiFlash to install the latest official firmware - "jasmine_global_images_V11.0.15.0.QDIMIXM_10.0" and after about 300 seconds it finished with "Success" but the phone remained black, without restarting. After restarting it manually, nothing seems to have changed, the bootloop issue remaining the same.
In recovery mode, it shows this:
"xiaomi/jasmine/jasmine_sprout
9/PKQ1 . 180904 . 001/V10 . 0 . 9 . 0 . PDIMIXM"
In Fastboot I get the following information:

your anti rollback is fine , so no problems there ... everything seems fine ...it just tells you your bootloader is unlocked and the different partitions etc
everything looks good , according to the output above, the best way to boot safely , is to change your active slot from A to B using fastboot
fastboot --set-active=b
if that fails you should just boot twrp custom recovery and "dirty flash " your rom
fastboot boot recovery.img
*take a backup in case you haven't yet ...
if it still fails to boot try flashing a custom kernel
if still fails to boot flash stock rom in Miflash in edl mode

Hi KevMetal, thank you for your help.
I followed your instructions and did the following:
- switched partitions from a to b but with no success - still in bootloop.
- installed TWRP (Pitch Black version) but I don't know how to "dirty flash" a rom. I wiped the cache and Dalvik cache. I get confirmation in the text console but on several different lines it keeps showing, in red letters: "Failed to mount ‚/persist’ (Invalid argument)"
- I don't know yet what a "kernel" is or does but I saw the option to flash from twrp. Can I flash any custom kernel? I saw there's a thread about this, I will check it out.
- I flashed again the latest stock rom in MiFlash - no success, still in bootloop.
What is keeping it from booting past that white screen with the coloured thin line in the middle?
Thank you.

if you can boot custom recovery .. wipe everything ..but everything ..and then install a custom rom ...reboot to recovery and then using orange fox recovery you need to search on web and flash the persist partition ..there are some .zips that can be used to wipe and restore your persist ( your problem is that your persist partition is corrupted) .. probably*... so anyway ..find a .zip file on the web for restoring persist ..( official global telegram) ..then flash it and then reboot to recovery once ..use power off function in recovery .. restart the phone and plug it into the charger and leave it to reboot 2-3 times spontaneously ..after a few reboots start using it ..it might bootlooop once or twice .. it's normal but it will eventually stabilize after a day or two

Wipe everything, start clean - I like this. Will come back with results, thank you.

Done. It's working!

Hi, I've done it and it is finally working!
I booted into twrp... wiped everything... installed custom rom (https://forum.xda-developers.com/mi-a2/development/rom-pixel-experience-t4062563)... restored persist partition following Aerobatic's instructions (https://forum.xda-developers.com/mi-a2/how-to/how-to-fix-sensors-camera-stock-pie-10-t3914885)... rebooted (after several failed attempts to reboot, the phone switched into recovery suggesting to wipe data in order to fix this problem - chose "yes".)... the phone started completely and everything is working normally.
Thank you, KevMetal for helping me through this. Otherwise I'd have renounced. Cheers to all contributors here!

Well, I celebrated a bit early. The interface works "buttery smooth" but there's one problem: no cellular connection. Wifi is working fine but no cellular. Although the phone recognizes that there's a sim card inserted, it has no signal, neither on sim slot 1 or 2. I tried with different sims on each slot or on both slots. It always shows an "x" on the antennae symbol on the screen.
I wiped the phone, flashed the latest official rom, booted and... still no cellular connection.
What could cause this? Should I flash another persist partition? Last time I used the one from the latest official rom (jasmine_global_images_V11.0.15.0.QDIMIXM_10.0). Thank you.

what did you originally do that caused this ? you must have messed around with stuff pretty extensively ... usually the wifi and sensor issues are solved by flashing persist
if your imei are all o's or there is no data you wiped your imei too which is different to just corrupting your persist
you might as well search for guides related to restoring your imei for a Qualcomm device be careful not to use mtk guides and search for a current one .. I've posted the fixes to this and the persist issue various times and don't feel like repeating the process ..you will have to dig a little ..you will need to copy your original imei's from your box and rerstore them using a specific tool .

New phone unresponsive (hardware issue?)

Afternoon all,
I recently purchased a Xiaomi Redmi 8 online (global ROM). I bought the phone cheap, the person I bought it off reported that "as been turned on once, However, when trying to set up the phone it crashed and hasn't turned on since. It still vibrates when the power cable is plugged in or the power button is held down." Since then the phone has turned on once randomly (everything working) but it then shut off an hour later.
The phone appears to be able to enter fastboot mode, but can't enter adb. I have been unsuccessful trying to unlock the bootloader (for reflashing purposes). I assume this is due to the USB debugging being disabled.
Below I've posted the fastboot device info and getvar.

Has anyone encoutered this issue before? At this stage my next move is to
try enter EDL mode (although, this requires authentification I've read?).
Could it be a hardware issue, or firmware? I have access to multimeters, oscilliscopes, etc,
are there any guides on test-points for Xiaomi phones?
If anyone could shed some light on this, it would be greatly appreciated.
Thanks,
Lachlan

If you require more information, I'm happy to try and provide it. Also, if this should be posted on a different thread, please let me know!

Hey guys,
I've found the issue with the phone so thought I'd post for anyone else who might have this issue. The issue was the screen ribbon connector. After removing the cable and then reseating it in the socket, the screen returned to normal

Between Soft-brick and Hard-brick

Just got my xz2 bricked. I try to install lineage OS on my xz2, but the system partition is not big enough(jap ver), so I decide to repartition it. But something went wrong with the parted, the partition did not created with given name but with a null value.
So the partition system_a, system_b, vendor_a, vendor_b, oem_a, oem_b is gone, physically.
By now my phone can only be boot into fastboot mode, when u try to boot into recovery or flashmode, it will tell u that device corrupt cannot be boot ,will power off in 5 sec.
In normal condition, it can be fix by reflash system partition but the system partition is no more so it wont help.
Also, due to the inaccessable flash mode, neither new flasher and flash tool will help.
Try to boot up from a img using fastboot boot boot.img it return this:

I'm wondering if there's a way to skip the AVB to force boot into recovery or manage partition under the fastboot mode，or boot my phone into EDL mode to save it

If your partitions are broken, You can try to use command:
fastboot oem format
It should be create new GPT table on eMMC for further flashing appropriate partitions, if partition table was modified.
If the command is successful, then you can try to restore the firmware. This guide should help.
