HELP! No wifi! :( - X Style (Pure) Q&A, Help & Troubleshooting

So basically I unrooted my device using the script that someone had uploaded on here and it worked perfectly, the only thing that didn't was the wifi modem! I have had this issue when I rooted the device but lost my steps I did to fix my xt1575. I have tried to flash files individually and researched the error and have found its because the bootloader may have been relocked but it isn't. And in developer settings OEM unlocking is ticked and USB debugging is ticked. I tried to rerun the script with same results. If anybody who has had an issue could help me that would be greatly appreciated! :good:

Reflas the erase modem1 and 2 commands and the HLOS command too. No need to flash the rest of the files. If you need more help or this is not clear enough let me know.

The "script" you used is likely really old. The original way if rooting this device was by writing a pre-patched boot image, well, that works great until the radios change, which they have a couple times.
You can probably get this working by flashing an old modem image and firmware, but you are just getting more and more mixed up in versions.
The right way to fix this is restore your pre-root backup, or flash the matching unmodified boot image with fastboot, and then rooting properly.

[A] For all of you, ending up in "bootloop" updating Android

I finally managed to install Android 5.0 Lollipop on my Nexus 4.
First I flashed it using the factory images and fastboot and it was working fine, but after one week the sensors did not work anymore. CPU-Z showed no avalaible sensors. So I tried to reflash system.img and then the misery started. I was not able to boot, having the 4 spinning dots for hours, even over night (~8h). I tried every combination one could think of, e.g. installing the factory image, sideloading the OTA, installing flashable zips of the stock rom, I also tried custom roms and formated and also erased every partition using "fastboot erase ... or fastboot format ...". Literally nothing worked except installing the Android 4.4.4 factory image. So I ended up having a nandroid of Android 4 and from time to time installing Android 5 which did never work.
Today I was using the file manager in the TWRP custom recovery and I thought Android 5 not booting may be due to the encryption I had, when Lollipop was running well, the next thought was to try to reset the phone to a "real" factory state, because factory reset in recovery may format /system and /cache etc but the rest of the root file system is still present.
After some search I found this tutorial and I am happy to say that it worked and I rebooted my phone twice without having a "bootloop".
http://forum.xda-developers.com/nexus-4/general/tutorial-how-to-unbrick-n4-t2347060
I did it on a Windows 7 laptop and followed the tutorial closely except I did not flash the flashfactory.zip he mentions (the links are down anyways), but I flashed the Android 5 factory image in fastboot. I have a 8GB Nexus, so I did not have to do the part for the Nexus 16GB.
I hope I can help some of you who tried to install Android 5.0 and ended up like me. First thing to try is always a factory reset, but if it does not work like in my case, this tutorial may help. If anyone has any questions, feel free to ask!

WiFi fix after restore to 5.1.1

I finally was able to fix my wifi issue. I have been unable to flash anything from my windows 10 laptop to my phone. Adb and fastboot worked fine except for the flash command? I reloaded all the drivers on numerous occasions just to make sure and also manually loaded them even thought the drivers are digitally signed and windows is happy. Still have not figured that one out yet. I tried the one step firmware batch file from http://forum.xda-developers.com/moto-x-style/development/pure-firmware-tuff-wip-t3224833. I put the NON-HLOS.bin, nowarning.bin and the stock kernal, v4tk-kernel-uber-alias-V6.img in the same folder as the extracted, Auto Flash Firmware script and ran the autoflashfirmware. bat file. To my surprise it worked. I still have the unlocked bootloader warning, I can live with that, however I now have my wifi back....Yea.... Thanks to all the people who devote hours setting up tools that help noobs like myself..... History,,, tried to root 6.0 MM on new XT1575 after bootloader unlock and twrp recovery. Soft brick because I did not read enough. Restore back to 5.1.1.. Lost Wifi until now.......

Soft bricked my phone, could somebody help me?

Hi everyone, sorry for a noob problem but I seemed to have soft bricked my phone and was hoping that somebody here would be able to help me out. I have an A2017U in the US.
A short history:
I had been using my phone on B20 rooted/locked with tenfar's tool for about 3 months now, and decided I would try and update it finally before the new year.
To update it, after reading it seemed I would need to unlock the bootloader to keep root on B29 so I decided first step would be to unlock the bootloader and then update to B29. I did the following steps today
1) Unlock bootloader using DrakenFX's guide here http://forum.xda-developers.com/axon-7/how-to/guide-how-to-unlock-bootloader-stay-t3461165 The unlocked proved successful and I was able to boot back into B20 after all the data was wiped, and I followed the instruction to backup the Boot in TWRP. All good.
2) I then decided to follow another of DrakenFX's guides (https://forum.xda-developers.com/showpost.php?p=68873482&postcount=2) to update from B20 to B29. I followed the instructions exactly again, but then the phone just hangs on the ZTE logo on boot infinitely. I wondered if I made a mistake when re-initializing TWRP after unlocking the bootloader. I did a search and found in "Mount" to uncheck "Mount system partition read-only" and unchecked it. The System partition however is unmounted, I'm not sure if that's normal now or not. Even when I check it, after rebooting it goes away. I've checked the MD5 of the ZTE_A2017U.B29_StockSystem_by_DrakenFX.zip file and it's good. I then flashed through fastboot to the new 3.0.3-0 TWRP which I'm now using, and still nothing. It appears I don't have an OS installed. I'm going to guess here the issue is with a setting in TWRP but I've tried everything I could find. Unfortunately I don't seem to have a copy of my stock recovery right now to flash either. I've tried several times to flash ZTE_A2017U.B29_StockSystem_by_DrakenFX.zip and reboot but to no avail. I even tried this tip from rczrazor to delete DATA first and others one by one (https://forum.xda-developers.com/showpost.php?p=69428659&postcount=136) but no such luck for me. Still stuck on the ZTE logo.
tl;dr - I have access to fastboot and TWRP, but apparently no ROM installed even though have flashed now multiple times.
If anybody could help me I would greatly appreciate it. I'm even willing to pay a few bucks in Paypal to help get me going again.
Thank you all in advance.

I have bricked my AXON 7 many times during the last week. The Zip files from DrakenFX are very good. But in case those were still failling...
First, check for corrupted downloads, just check the zip file integrity using 7zip, winRAR or any other tool.
Use TWRP 3.0.3
Try a different ROM such as ZADMix or even CM13.
If everything fails:
Flash TWRP 3.0.2 signed.
Flash the original Stock B29 Boot partition and reboot to recovery
Flash again the verified DrakenFX files.

[GUIDE] Fix PERSIST.IMG Loss Of Finger Print Sensor

New video guide below
VIDEO GUIDE
1. *VERY IMPORTANT* We need to back up your broken persist.img and store it in a safe place. PC preferred. We will need this later. Do not leave the backup on the device as the next step will wipe the device.
*IF YOU LOOSE THIS PERSIST.IMG BEFORE WE MODIFY IT WITH A CALIBRATION, YOU LOOSE ALL CHANCE OF FIXING THIS YOURSELF*
*IT HOLDS IMPORTANT FP CALIBRATION DATA THAT WE WILL BE OVERWRIGHTING IN THE NEXT FEW STEPS*
Note: This requires root​
Type this into terminal or ADB shell with root privileges.
Code:
dd if=/dev/block/bootdevice/by-name/persist of=/sdcard/persist.img
Backup the partition to another device. Preferably a PC as you may need one in the later steps.
2. Next we have to restore our OS to an earlier OOS. (10.5.4 is what I used and recomended)
Use the MSMTool to restore your device to 10.5.4.​Note: You will loose your unlocked bootloader and will be required to unlock your bootloader once more.​
Guide and Source for MSMTool
MSMTool 10.5.4 Download
3. Next step is to unlock the built in 'Factory Mode' I have a guide on how to do this below.
[GUIDE] Unlock Factory Mode *root*
4. Now we need to perform a FP calibration. We want to fail.
Enter Factory Mode as shown in the previous guide. (*#801# in the stock dialer)
Swipe over to "Device Debugging"
Select "Finger print test"
Select "Finger print calibration test(Pure White - 90% Blue)
Select "Start Test"
Keep on going through the tests (You must hold an object or your finger over sensor on all BUT THE BLACK RUBBER TEST of these test for it to work!)
The test will fail and this is what we want. There should be a lot of red lines, if you only have one or two try again.
5. We need to extract the the old broken persist.img
NOTE: It is important that we extract the backed up persist.img as it has been unmodified by our recent calibration. This persist.img although broken still has all our working calibrations on it including Finger Print calibrations.
The way I did this is by opening it extracting it via 7-ZIP on my PC​
Once extracted move the 'DATA' folder and the 'ENGINEERMODE' folder to the root of your sdcard.​
6. Download a root explorer. I highly recommend 'Solid Explorer' from the Play Store.
Open 'DATA' folder and delete 'gf_persist.so'
Select the 'DATA' and 'ENGINEERMODE' folders you just put on the device and place them at /mnt/vendor/persist/
It should ask you if you want to keep the old or new files. Select to keep the new.
Reboot.
7. If you followed all my steps correctly this you should be able to go into settings and add your fingerprints.
Why does this work?
Good question... I think what is happening is something in the persist partition breaks which causes the device to think that the sensor is not calibrated when in fact it still is.
When we start and fail a new calibration this fixes whatever was broken in our partition. But now we have a failed calibration.
So what we do is take the files from our backed up persist partition and move over all the necessary files that have our original calibration. But now our partition has the part of it that wasn't working fixed.
I spent a good many days working on this fix (1-2 hundred hours or so). I hope you can be respectful if you have issues. Please kindly ask below and I'll do my best to help.
Thanks worked on.my TMobile OnePlus.
I can confirm working on OOS 1.5.6 too. I downgraded from 10.5.9 with downgrade rom, which restores OOS to 10.5.6, and followed your guide and it worked as a charm. The only problem is that i cannot lock back the bootloader, cause it breaks FP again. Did you maybe try to lock it to try? Nice work man.
T-Mobile OnePlus 8 here. Stock firmware, orginally had my bootloader unlocked, rooted with TWRP and Magisk, backed up modem, converted to international firmware (10.5.7), lost signal, had to restore modem, ota'd to 10.5.9, unlocked bootloader again, rooted, etc. All while having a working FP the whole time. Ended up flashing EdXposed via Magisk, broke SafetyNet, etc, did a factory reset on TWRP (3.4.0-1 test), wiped data, rebooted recovery, rebooted system, booted back to TWRP. Installed Magisk to see if it'll boot with root, same thing. MSM'd back to T-Mobile firmware, then converted to international again. After the conversion was done and I unlocked bootloader and rebooted to system, my FP was broken. Ended up MSM'ing back to T-Mobile stock to see if it would work again, nothing.
TL;DR does this method only work if I had a working FP to begin with like it did stock out of the box?

Just follow the guide, you'll have it working. You just have to backup your current persist

So back it up even though it's broken? I'm on T-Mobile stock again, locked BL. Should I unlock, root, then pull persist and back it up?

Exactly, a T-Mobile user confirmed guide to work, check 2nd post
While on 10.5.7, unlocked bootloader, I flash TWRP, then reboot, and it boots back to TWRP. When I flash Magisk 20.4 zip in TWRP, it goes to boot, then enters CrashDump Mode. When I try and use the flash-all to downgrade to 10.5.4, I get a bunch of fastboot "cannot flash critical partitions" errors, it fails, and goes back to CrashDump Mode. What am I doing wrong? Also, is it really necessary to downgrade to an earlier version of OOS to use Engineering Mode or can I use 10.5.7?

When you unlock bootloader, only boot into TWRP, then install magisk, i thin it Is still recommend to only boot into TWRP, not to flash it.

Thank you so much, that worked! New problem, what do I do since I can't downgrade to an earlier OOS (10.5.4)?
Performing the test on T-Mobile 10.5.7, when performing the test, nothing is failing after pressing start test. Its all passing, what should I do?
When trying to downgrade using the 10.5.4 MSM Tool. it gives an error of "Unsupported Target TMO" and "param preload" and fails.

Did you follow the instructions in test exactly? In second test you must't press the sensor.
Can help you with TMobile model, I have international one.
I figured it out. I was just being a dumbass I guess. Has anyone noticed the fingerprint sensor not being able to read that well compared to before it was broken? It seems like it fails a lot more before it succeeds. Unless now that it's working, we can perform the calibration again and it'll work better?

Don't know about that, mine works just fine
So I think I messed up, I ended up performing the calibration again, while it was already working, and now it says "fingerprint hardware not present" any suggestions on how to fix? I performed the instructions in the guide (again) and nothing worked. When the error pops up, if I press back, the error message goes away and the FP icon is there. When I tap on it, it lights up white but doesn't vibrate or register anything. I already used the MSM tool to go back to Tmobile stock, then used the fastboot ROM to go to Global 10.5.7, followed the guide again, still nothing.

I tried that, multiple times. Still not working. Is it possible for someone to upload their persist.img so I can try it or is it device specific? Granted, I pulled my initial persist.img from stock rooted Tmobile ROM AFTER I broke it even though it worked before (long story). I wasn't able to downgrade to 10.5.4 because when I tried using the MSM tool, it gave me a TMO device error and I couldn't use a fastboot ROM to go to 10.5.4 cause it kept entering CrashDump mode every time it tried rebooting to fastboot to finish the flash process .

What about someone else's DATA and ENGINEERINGMODE folders? I've tried everything. Even recalibrating multiple times. It's not giving me a bunch of errors like it did before, just one error. The last error is FAIL! OPERATION_STEP_GET_KB_CALIBRATION TEST FAIL:GF_ERROR_GENERIC
Just wondering, what is the point of downgrading to an earlier OOS? If I was able to do it on the Tmobile firmware with success, is there an importance in downgrading?
Thank you so very very much!!! I have a T-Mobile 7T Pro 5G McLaren which hasn't had a working fp in almost 2 months. I hadn't made a backup of persist before the fp broke, so I thought I was completely screwed. Luckily, I did make a backup of persist before trying to use the fp calibration tool myself without any luck shortly after it broke (basically just clicking stuff and guessing lol). Found this thread and I had my FP scanner working again perfectly in less than 15 minutes!!!! Thank you soooo much for all the hours and effort you put into figuring this out!!!!!!!
Didn't have to run the msm tool to revert to older version of OOS and lose all my data either!!
Just one question and it's just for my curiosity. Why do we delete "gf_persist.so" from our original persist.img before copying/pasting into /persist partition after "calibration"? Is gf_persist.so not a file containing part of the original calibration? Is that the file which is being fixed by running the hidden calibration commands?
If anyone can help me, it would be much appreciated. https://forum.xda-developers.com/oneplus-8/help/broken-persist-img-problems-t4129587

Soft brick on oneplus 6T after version upgrade from Lineage OS

Hi there,
So I unknowingly did something kinda risky and of course, it backfired. I used the in-system update feature of linage OS to upgrade my version on my Oneplus 6T. Can't exactly remember which one the old version was, but it was at least 4 versions older than the newest nightly one. Afterward, the phone got stuck in a boot loop. Also, in recovery, it can't bind/ mount the system, because there is no file directory. "E:Failed to bind mount /mnt/staging/emulated/media/0 to /storage/emulated: No such file or directory." I tried the following:
- went into recovery, factory reset the device, then flashed new clean lineage os [multiple different versions]. Gets back to boot loop afterward. (note that Fastboot shows no bootloader version or baseband version)
- tried unlocking the bootloader via fastboot flashing unlock. It fails with error code: (remote: Unrecognized command flashing unlock)
- tried copying the contents of slot a to b, in case one was severely outdated as the cause for the soft brick as stated in this guide. Didn't change mentioned issue after flashing os.
- installed Qualcomm USB drivers, to get the PC to detect the phone as a USB device
- after that, tried using the ms-downloader tool to reset and re-flash the phone. It does not get detected and the downloader tool waits for the full 15s before returning the error for no detected device.
- tried unlocking the bootloader itself via fastboot flashing unlock_critical. same error as with normal unlock: (remote: Unrecognized command flashing unlock)
Maybe overwriting the possibly corrupt bootloader would be a good bet, but as mentioned, I cannot unlock the device to make the command for that useable.
Hey, so I am not really knowledgeable enough to help fix this, but I did notice one thing: Why are you using the wiki page from Lineage for the OnePlus 6 (enchilada) instead of the 6t (fajita)?

I didn't even notice it was for enchilada, but iirc the file I loaded was only to copy the contents of slot a to slot b. I could search for a fajita version of this. Still, thanks for your reply.
Hi there,
I have the exact same problem. After updating my OP 6T, the cell phone was broken. It's stuck in a reboot loop. Which surprises me, however, because the documentation for this device type recommends that the update be carried out using the system's internal update process. I also noticed that some OTA updates work and some don't. Unfortunately, this is the only way to make use of it very little fun because you never know if the phone is working again when you update. And the security weaknesses show that updates are also important for Lineageos. thanks for the feedback

Whatever you do in your device,they will not touch critical partition such as bootloader and many more of it, do u still have twrp or other recovery on your device?

Tell me the exact problem you with your phone and maybe i can help
once again,
today got informed via updater that a new update is available. I try do install it, but now i stuck again in recovery. And the only think i can do is a factory reset and everything is lost.
can anybody give an info if it is safe to update the 6T trough OTA? It doesn't look like that.

Oof, I thought mine only got bricked because I tried to upgrade across 4 versions. It seems as though even normal updates now cause soft bricks, neat.
I tried again today but there seems to be a connection to the error. I had an update pending, which could be installed without any problems. After the restart, I was informed that there was another update, after installing this update there was a total failure again. Could it be that this is somehow related to slot A / B?

Why don't you try to flash Stock rom on both slots via MSM tool and then just try ota to update to latest build for you specific device
How can i verify if there is an difference between slot a and slot b?
If i flash the stock rom i will be back on oos and that is not what i want i will continue using los, or do we have an idea missmatch there?
thanks for help
