[Q] Please help, I think I bricked my phone :(

I went to flash the latest version of Mahdi ROM, which I have done many times without a problem. This time, however, the patch.zip that I downloaded failed to install and then I was stuck in a fastboot. I found another post on here where someone said that putting certain commands into the prompt would fix it so I made sure that I had all the right files for my LS980 and went ahead and did it.
These are the commands I followed that got me to this point:
fastboot erase boot
fastboot erase aboot
fastboot erase recovery
fastboot erase laf
fastboot flash boot 6-boot.img
fastboot flash aboot 4-boot.img
fastboot flash recovery 10-recovery.img
fastboot flash laf 11-laf.img
fastboot reboot​
But now I can't seem to bring up anything and I've tried powering it on, going into recovery, and going into download mode but none of those things seem to be working. When I plug it into my computer, it makes the little sound and it's recognized but only as an E: drive with one lonely folder in it titled "image" and then I get a bunch of pop ups saying that "You need to format the disk in drive S: (and other various letters) before you can use it".
I really hope someone here can help me and that I haven't completely ruined my phone because there's no way that I have the money or means to replace it.

I wasn't able to fix it at all and ended up going to Sprint and getting a new phone. I basically just said it stopped charging correctly and then I woke up one morning and it wouldn't turn on. They took it as a hardware issue and I got it replaced. Thank goodness for Total Equipment Protection. I'm not sure who your carrier is, but Sprint gives two free replacements (as long as it is hardware or something similar) and then it's $25 for every replacement after that. Needless to say, I am going full stock and sticking with Nova Launcher this time around.

You could have tried to flash stock firmware. Exactly same thing happened to me. Flashing stock firmware solved the problem.

I should have said I fixed the problem by flashing stock. All is ok now.
I just rooted again and am trying to figure out how to avoid the same problem, which happened when I tried to install TWRP via AutoRec. The thing is, I have the F320K version and it doesn't seem to like the custom TWRP in AutoRec. But I don't see an alternative, yet.
I'm missing something.

Install the Autorec specific to your model. There should not be any problem cause most of us used autorec to install twrp.

I did that, but got the white line issue and didn't see the fix from Cloudyfa until today. I guess I'll try it again, knowing I'll get the white lines. Kind of freaked me out a little.
I'll let you know after the process, tomorrow. Thanks.

Help really need here, big issues

Hello to everybody, so i was thinking my nakasi was really dead this time, the last thing i did was flashing a 5.1.1 rom next when i rebooted got stuck on lolipop boot loop so i restarted the tablet
manually to access the recovery, and to my awe, i couldn't no more access the recovery ! (latest twrp) tried again and again nothing, no recovery no bootloader, can't start the OS
always stuck on google logo with the options above, start, bootloader, recovery etc, today i realized i could access the bootloader and fastboot mode (ADB recognize my device when i type fastboot devices)
so i tried flashing stock image and stuff with no luck, tried many stock roms, tried wug's toolkit and the flash all.bat still no luck, i get all kind of error messages here is a screenshot, help is really appreciated if there is anything i can do to save it :
View attachment 3305126

the problem seems to be that i can't write the things i send to the tablet via ADB, tried the NVflash recovery today and got :
View attachment 3306049

Have you tried not imputing the full file address as you have the emulator already running from that location.
So recovery command would be.
Fastboot flash recovery "name of recovery Img file here"
Just make sure that the image file is in the platform-tools folder.
Probably not your issue but its going to save you some typing.
Good luck

Thank you for the tip I'll certainly use it, but i don't think it is the culprit since as you can see in the screenshots
the files get sent successfully but cannot be written, my bootloader is unlocked by the way

Did you try the latest factory image? I noticed you are flashing a very old bootloader, possibly the first one? 4.23 is the current version.
Where is flatline_grouper.img coming from? I've never seen that.

Hello kind sir, of course at first i tried the 5.1.1 full factory image with the NRT toolkit and got the same writing errors next i tried many bootloaders
(one of them found it here as a 100% working bootloader) the Flatline is the recovery of the NVflash tool where you can access it to unbrick full bricked N7s
if you got blobs.bin of your N7 backed up (clearly not my case)
the flashing writing error i get it with everything i try to flash, recoverys bootloader system etc
when i send them with the flash all command they got sent to the tablet okay, but when writing i get the errors
i don't know but there is a small informations if that can help, before it broke my system was in EXT4 and all the rest in F2FS

It's entirely possible your memory has failed. I'm reading more and more people running into corrupted memory issues.
You can get a replacement motherboard cheap on eBay if nothing else works.

I'm still hoping for a software solution since my fastboot works fine, I'll let the motherboard solution my last i guess

Hello some news about the still staggering situations : when the tablet is off and i put the charger i get the battery refiling animation ! so that mean the bootloader isn't broken
and i still can access fastboot mode, even when i push a bootloader i get a signature match message, but the problem is still that the things i push can't be written as i'm still getting a :
FAILED <Remote: <FileWriteFailed>> changed usb cables, changed ports, the last time the tablet was working i had the system on EXT4 and the rest on F2FS, maybe if i can convert everything to EXT4 ?

[SOLVED] Mi A1 restarting each few minutes after flash.

Hey,
After hard bricking my Mi A1 and flashing an official android 8.0 stock rom, it is restarting every few minutes. First goes the unlock boot loader warning screen, then the mi screen and android one screen. It then goes onto the setup menu. I am able to go only to the point to enter my name. Depending on my setup speed, it becomes unresponsive at about that point, just restarts and goes back onto the lock boot loader warning screen. I tried re-locking the boot loader, but it only went to the mi screen, and again the process repeats. Please note that I can't flash a boot.img partition, says partition table doesn't exist.
**********************************************************
SOLUTION:
Place persist.img into the root of phone(not in any folder), flash twrp.img INTO THE BOOT PARTITION, and then reboot to recovery. You will see the TWRP loading screen. Go to Advanced-->Terminal--> and execute the following:
dd if=/sdcard/persist.img of=/dev/block/mmcblk0p27
And go back to Restart--> Reboot to system.
The persist should b back!
Now use Qualcomm IMEI write tool to restore your IMEI and MAC address!

Try flashing a custom ROM, then reflash Mi A1 stock OS

There has to be a way to manually make the persist partition writable, since the service center somehow knows how to do that...

nope there isnt, if you have flashed every rom available using mi flash tool hasnt solved your issue.
only hope you have is clean flash stock ROM with locked bootloader, go to service center and tell them it happened after you updated to the latest security patch.
first they will flash using EDL cable (deep flash) if that doesnt help they will replace the whole motherboard (that's how my issue was solved)
i recommend you to follow this procedure.

Nothing was charged not even a single penny, i just told them it started after i updated to oreo, even they said its happening because of oreo, but you gotta have a locked bootloader.

I've already tried using it without success because it didn't detect my device, but luckily i managed to repair my phone by changing the slots with fastboot command line tools where i still had oxygenos running.
Thanks though, how do i mark the thread as solved?

The MSM tool requires special drivers and your phone to be in a special boot mode, something like holding volume up while plugging it in or something.
Glad you got it fixed without the MSM tool though!
As for marking the thread solved I can't help with that unfortunately, sorry .

Severe Issues after uninstalling Magisk - Motorola XT1926-7 G6 Plus

I will try to be as brief as possible, but explain in detail what happened to my moto g 6 plus XT1926-7.
I was running the stock firmware from the:
RETLA
Channel from march 27, 2019:
XT1926-7_EVERT_RETLA_9.0_PPWS29.116-11-2
I unlocked the bootloader using the info provided by motorola.
I used a TWRP installer which I found in this website and successfully installed twrp 3.2. I quickly realized that this version did not decrypt the data partition.
No problem, using the boot command in fastboot, I can load TWRP 3.3 which does decrypt the data partition.
I installed magisk V19.2
I then installed 2 magisk modules:
Viper equalizer
Pixel 3 ( something ) which makes the UI a little nicer.
The phone worked with no problems for months until the July OTA "update unsuccessful" nag screen started showing up every 10 seconds.
I read from several sources that an unlocked bootloader phone from motorola won´t take OTA updates. Fine. I lived with it for a couple of weeks until the nagging screen became unbearable.
I decided to unroot, relock the bootloader get the OTA and move on with my life.
I uninstalled magisk from the magisk manager and the phone immediately went into boot loop.
I´ve been using TWRP for years now with several phones, and each time i´ve had a problem, i just restored from the last backup ( which i do at least once a month ) and move on.
This time i used the full twrp backup from a couple of weeks ago, but it didn´t work.
The phone still bootlooped. It either rebooted at the "verity disabled" screen or it went straight into TWRP 3.2
I decided to use the original backup i did several months back when i first installed magisk and it didn´t work either. First time in years that a TWRP backup didn´t work.
I read in several threads on several websites that the only thing left to do was to flash stock rom from motorola in fastboot basically file by file.
So I did it and flashed the original stock rom for my device from the RETLA channel:
XT1926-7_EVERT_RETLA_8.0.0_OPWS27.113-89-5
The phone booted into android but both IMEI and wifi mac address were gone. So no carrier signal and no wifi.
I read from several threads that a backup from the EFS and persist partitions would solve this, so I tried both backups of these partitions i had, but nothing worked.
fastboot would read the IMEI number with the get vars command, but android would not recognize them.
Then i found a post here from a couple of days ago of a person who had the same problem and by flashing the latest stock rom fixed this.
So i downloaded:
XT1926-7_EVERT_RETLA_DS_9.0_PPWS29.116-11-6
from the RETLA channel and again proceeded to flash via fastboot file by file.
this time android booted and it did load the both IMEIs and the wifi mac address BUT, wifi disconnects every 10 seconds and the carrier signal is worse.
I then tried the lenovo assistant as suggested in another thread in this website and used the flash / recover feature. Same thing happened. android boots but wifi signal is lost every 10 seconds and carrier signal gets cut off at regular intervals and is very weak.
This has rendered my phone basically useless. I had been using a Moto G2 for many years with no problem and i bought this one just a couple of months ago.
I don´t mind flashing the phone again, and i´m good at following step by step procedures.
It would be super cool if someone would point me in the right direction on how to fix this.
Thanks in advance

This is how I managed to fix my Moto G6 plus
I was able to fix my phone so I will reply to my own post:
It took me almost 4 days to fix the phone. It took a lot of reading and MANY hours of trial and error, so I´m going to describe what I did in order to help anybody with the same problem to save themselves a LOT of time.
As it happens, I found out that a lot of people have run into the same problem of bootloops after uninstalling magisk and then even after flashing the stock rom, had no wifi and no carrier signal. Hence, a useless phone.
Prerequisites for this solution:
Be able to boot your phone into bootloader mode.
If you don´t know what bootloader mode is, do your research. It´s very simple to get to it. Just power off your phone and then press the power and volume down buttons simultaneously for a couple for a couple of seconds. How to use it is another matter entirely. Again... do your research.
1. Before disaster strikes... Do not use an installer script to force install TWRP on a phone which has A / B boot slots. If you plan to install Magisk later, do not force instal TWRP. Moto G6 Plus is such a phone. This is written very clearly in the Magisk troubleshoot wiki. I wish I had read this before.
If you want to use TWRP ( and you should ), load TWRP 3.3 or newer temporarily from fastboot with the boot command. It will be able to decrypt your phone´s data. TWRP 3.2 does not.
To decrypt you will need to have a pin or pattern unlock set previously on your phone.
I used a script to force install twrp 3.2 to my phone. It´s useless since it can´t decrypt the phone and it was surely the cause of all this mess.
I´m not blaming TWRP or Magisk. This mess was all my fault. I´ll tell you about it later.
2. I have a TWRP 3.3 full decrypted backup of ALL the partitions of the phone from last week. I always do regular backups. I´ve been using TWRP for years and it has always served me well. This time it didn´t. My bad, not TWRP´s. I flashed the backup to the phone and it kept bootlooping. I flashed the backup about 20 times!
3. If you´re in this mess already because you forced install TWRP and you uninstalled magisk and your phone is bootlooping, you will probably have to wipe your phone and flash the stock ROM appropriate to your model. Trust me, if you´re not an android / linux guru, your only way to get your phone back will be to wipe your phone completely. I realized this the hard way.
Don´t flash the original ROM for the G6 plus ( android 8 ). Use the latest build. It seems motorola took note of so many people having the "no carrier / no wifi signal" problem, so they have included a fix for this in the latest android 9 releases. This has worked for other people, It worked for me. I don´t know for sure if it will work for you.
4. Here´s one important piece of info. For motorola phones it is very important to have a backup of these two partitions:
EFS
PERSIST
I´m not 100% percent sure of all the info they have or the entire purpose that they serve, but I now know 1 thing. These two partitions have critical and unique information about your phone.
They provide the unique IMEI info. Wifi Mac address info. Baseband info, which is all the technical carrier signal communications stuff, etc..
How do you back up these partitions? Use a custom recovery like TWRP or similar. If you want to mod your phone, please do your research on the software you are going to install. I usually do it, this time around I just winged it, and look where it got me.
5. Here´s another important piece of information to take note of BEFORE disaster strikes. Write down on a piece of paper and store in a safe place ( a txt file on your pc will do ) the following:
Your phone´s exact model Nº. Mine is:
XT1926-7
Go to settings: tap System, tap about phone and write down which software channel you are on.
Mine is: RETLA
This is important because it determines which stock ROM you will need to download, as not all ROMS for this device are the same. The XT1926-7 is a dual SIM phone so NO. Not all versions of the stock rom will work.
6. In order to download the correct stock ROM for your phone, on your computer, go to:
mirrors .lolinet .com /firmware/moto/evert/official/
This website is one of several which offer stock roms for motorola phones. You can use this one or search around for another one.
The website will show you a directory structure of all the different software channels available for the motorola Moto G6 Plus. Choose the folder appropriate for your phone.
Remember mine was the RETLA channel?
These are the only channels which offer stock roms for the XT1926-7
RETLA
or
TEFCO
or
TEMX
or
TIGCO
If your phone is factory unlocked you will probably have to use the RETLA versions.
Within the correct folder, look for the latest ROM for your model. Pay close attention to the name of the rom. The first section will indicate what model it´s intended for. For example, in the RETLA folder there´s ROMS for 2 different models:
XT1926-6
XT1926-7
The correct file for my phone was:
XT1926-7_EVERT_RETLA_DS_9.0_PPWS29.116-11-6_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip
Please do your research and download the right file for your phone. If you´re not careful, it will lead to bigger problems.
Please also download the original factory version of android 8 ( oreo ) made for your phone. you´re gonna need 2 files from that ROM. In my case the file was:
XT1926-7_EVERT_RETLA_8.0.0_OPWS27.113-89-5_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml
The stock roms are about 2 gigs in size.
6. Next you´ll need to download the right tools to flash the stock rom to your phone.
I´m assuming you have downloaded and installed the latest motorola USB drivers for your computer and installed them. If you haven´t. The time is now.
The internet will tell you to download the Android SDK platform tools. This package will give you fastboot and ADB.
Don´t download it. The "vanilla / run of the mill" version of fastboot won´t help you.
Motorola created a modified version of fastboot for their phones, which flashes a motorola phone in specific ways. It´s called: mfastboot
I saw the procedure differences while running mfastboot in the DOS window. In the end I was able to fix my phone because of the differences which mfastboot offers. You´re gonna have to trust me on this one.
Since the motorola version of fastboot is small in size, i´m going to attach it to this comment. Look for the attached file named:
mfastboot_adb_tools.zip
7. Create a folder on your hard drive. It doesn´t matter how you call it. Just remember where it is. Unzip / decompress the entire contents of the file:
mfastboot_adb_tools.zip
you just downloaded to that folder. it should look like this:
Then unzip / decompress the entire contents of the:
XT1926-7_EVERT_*YOUR-CHANNEL*_DS_9.0_PPWS29.116-11-6
to the same folder. it should look like this:
Now we will need just 2 files from the:
XT1926-7_EVERT_*YOUR_CHANNEL*_8.0.0_OPWS27.113-89-5
Unzip these two files to the same folder where you have unzipped everything else:
8. It is now time to boot your G6 Plus into bootloader mode. With the phone turned off, press the power and volume down buttons simultaneously for about 5 seconds.
You´ll get a black screen with the android robot laying on its back. At the bottom of the screen you will see a piece of text which reads:
Connect USB Data cable.
Do it. Connect the usb cable to your computer and then connect it to the phone. the connect data cable message will change to a green sentence which reads:
Transfer mode: USB connected
9. On your computer, return to the folder where you placed all the files. Look for a blank space with no files within that folder and press the shift key + mouse right click. out of the context menu you get, select:
open command window here
You will get a black screen with a white prompt.
Now let´s make sure your phone is connected to your computer. In that black window type:
mfastboot devices
The result should be your phones serial number followed by the word fastboot.
If you got nothing or any sort of error it means you phone is not connected properly or some drivers are missing. troubleshoot that and come back when your phone is actually connected.
10. OK... let´s start flashing the files. The following series of commands I copied from another post in this website. I did not come up with this set of commands and I will repeat that i´m no expert. This worked for my particular situation and by no means i can guarantee that it will work with your phone. All I´m saying is that if you´re desperate and at the current moment you have a soft bricked phone, go ahead and try this.
In that black window, start copying these commands 1 by 1. Wait for them to execute and get an OK message from the phone. If you get an error try that command again. to paste the command in the black window ctrl + v does not work. you have to right click your mouse on top of that window and paste the command that way. When you´ve pasted the command, press enter to execute.
These are the commands:

mfastboot flash partition gpt.bin
mfastboot flash bootloader bootloader.img
mfastboot flash modem_a NON-HLOS.bin

mfastboot flash oem_a oem.img
mfastboot flash oem_b oem_other.img
mfastboot flash vendor_a vendor.img_sparsechunk.0
mfastboot flash vendor_a vendor.img_sparsechunk.1
mfastboot erase carrier
mfastboot erase userdata
mfastboot erase ddr
mfastboot oem fb_mode_clear
press power button on the phone and restart it.
It might take a while to boot, but if and when you see and hear the "hello moto" greeting, it means your phone has been fixed.
You might end up with a restored phone, but no wifi and no carrier signal. Then what you will need to do is to flash the backup of your EFS and Persist partitions using TWRP, and then retry the whole procedure again.
This is the way I fixed my Moto G6 plus.
It wasn´t a perfect fix for me. Since I had forced installed TWRP 3.2 with an installer script, that did something to the boot partition and now even after reflashing the entire phone I don´t have any type of recovery.
No stock recovery of any kind. It´s not a problem since we can boot TWRP temporarily from mfastboot and in bootloader mode just like the procedure we did with the stock rom. All the rest is back to perfect working condition.
I was also able to make a new full phone backup.
I will tell you this, now I know that all this mess is not TWRP´s or Magisk´s fault. They are fine programs. It was my fault due to a lack of research. I shouldn´t have mixed them both in the way I did.
I forced installed TWRP to my phone because it was what I was used to and I didn´t read any instructions for Magisk which I had never used. I come from the SU era.
I hope this wall of text will be of help to anyone going through the same situation with a Moto G6 plus.
Unfortunately nobody replied to my original post so I had to solve this on my own. The good thing is that I did manage to fix it.
I will repeat it one more time. I´m not an android expert. Not by far. I´m not saying this procedure will work for your particular problem. I´m only sharing what worked for me and I hope it will work for you. If it doesn´t. Keep looking and researching.
GOOD LUCK.

Sorry for spamming the thread, i got out of the boorloop by installing again the oreo stock rom (with no imei nor mac). After doing it i did the whole procedure again and it booted but still having the wifi/mobile data resetting. I will redo everything againand if after several times i get to nothing i will post another question here.
Sorry and thank you

Still doesn't work

Do you have a backup of your EFS and Persist partitions from when the phone was in working condition?
You could use those to restore you Emei and wifi mac address and then flash Pie again.

No, I don't have one. I thought that in this guide I didn't need the backup but apparently there is no solution for now if there is no backup.
Thank you

Like I said in my post, i´m not an expert. I just posted the procedure which worked for me.
I did have a backup of those partitions and I used them several times and it did not work. Are you using mfastboot instead of regular fastboot?
I would try the procedure several times.
Buena Suerte.

I tried it several times but as I said previously there is no point doing it with no backup ( not my words, I talked to a guy that develops most of the g6 Plus roms and told me for now there is no solution without the backup, it was over the Spanish telegram group. I highly recommend it, if you want to join talk to me at the PM because I can't share social network on posts)
Thank you for your advise, if I am able to solve it I will let you know

I screwed up my efs/persist and didn't have a backup (a few months ago).
So can I please have a copy of the backed up efs and persist partitions? I should be able to go through and replace any ids (mac address and imei) with my own. If I figure it out, I'll write a guide on it too .
I have the same device model as you (XT1926-7 RETLA).
I've also been looking at this (https://forum.xda-developers.com/razr-i/development/pds-partition-fix-risky-faint-heart-t2813292) which is for a different problem with a different phone where someone posted their pds/persist partition, but it looks like the data in those partitions are just stored plainly in binary.

Well yes, but actually no. You can't use another's device efs/persist because these files can only be read by the device that created them
However I found a magisk module that fixes several persist issues. It is called PIXELARITY

Does this actually fix the persist issues permanently? Or does it just work around them while it is installed? I am in the same boat as others without a proper backup of efs/persist. If it fixes anything I will be happy.
Also, how are you getting the Magisk module installed? I have no wifi or cell service so the Magisk app can't download the module. Tried just downloading the module repo .zip file and manually installing from that, but magisk is not recognizing it as a valid module. I almost never install Magisk at all let alone modules, so I am a bit in the dark on the general procedures.
Edit: Wound up getting it installed with a USB ethernet dongle to get some form of connection. But the PIXELARITY mod did absolutely nothing in my case. Flashed stock and I have IMEI and Wifi MAC Address back, but they are now both cutting out in the same way as yours. The Magisk module did nothing there either.

I forgot to post it, for mi actually it just partially worked ( permanent). I said partially because I lost my IMEI.
I am now trying to use the efs that doesn't have an IMEI to patch it up with mine and maybe make it "universal" and share it to other people and they just patch their IMEI.
However it is quite complicated and I am not having a really advanced progress on this.

I have just seen the edit.
What worked for me I believe it was a chance and I can't recall exactly what I did before it "workerd", I did a lot of things, as I believe you also did.
I would try following the guide up here and installing the module, maybe that's what I did.
