Sudden WLAN failure - Zuk Z1 Q&A, Help & Troubleshooting

Hi,
Phone was doing great and overall it was really awesome experience. Suddenly I noticed I cannot turn wifi on. After restart phone started to bootloop, reflashed system, restored twrp 4 days old backup - nothing worked. I wiped everything even sd card, still bootloop. Sim cards seems to work but only in 2g.
Board check says SD and WLAN fail, device status says WIFI mac address is unavailable.
Guys, any ideas how to fix it or is it hardware issue?

[Q] Something went wrong

I formated my sd card from recovery-windows and i got a bootloop when i rebooted it.
No more access to recovery-windows, i took off my sd card, bootloop again, i had to go to recovery with red triangle, pull off battery, disconnect from usb and reboot to make it work.
Factory is reset but no more network even with proper settings, and i can't access the recovery windows without having bootloop all over again. I got a mysterious IMEI SV number now too.
Strange things is the drivers are mad in hboot and recovery now , i got something like this.
I don't understand what went wrong, can someone point me in the right direction to make it work?

Yes, with blay0 0.7 currently on it.
So the network came back after one complete day without it. Don't ask me why.
But i have other major issues:
-SD Card slot not recognize, tested with different SD cards, same result.
-Bootloop when i boot my phone, only way to get around it is to plug it in usb, don't ask me why too.
-Weird Drivers still nuts with HTC DIAG, Qualcomm CDMA Technology not recognize.
I didn't know a simple SD card format from recovery can cause so much trouble :'(
Undoubtly the native drivers from Hboot disappeared, and without sd card nor recovery from PC, i don't know how to bring them back.
Can someone help me please, i don't want to lose it :'(
Okay it's a classic USB Brick sorry for the inconvenience.

[Q] Nexus 4 cant detect network

Hi guys, need some help here. I woke up this morning with my nexus 4's battery flat and so i went to charge it and turned it on while it's charging. However it couldnt detect any network and it's stuck at emergency calls only. I tried rebooting several times to no avail. I also did a factory reset but its still stuck at emergency calls only. Im on 4.4.2 stock, bootloader locked. Any help would be greatly appreciated!

Dial *#06#. Is your IMEI still correct? Try turning it off removing and reinserting the sim card. It could also just be issues with your network.

Nevermind, figured out the cause of it already. My sim card was broken. Thanks anyway!

J5 prime [SM-G570F] - signal issue on secure startup

Hi Everyone,
I've encountered an issue with the secure startup feature. On boot after providing the start up pin, phone take a moment showing a unlocking animation and then load to the home screen. The problem starts after that with no signals and unable to access mobile networks option (says insert sim though the sims are identified at the sim manager). I've done restarts but no use, then check the IMEI codes and it was unavailable. I thought the EFS folder is surely corrupted and I need it to give it to service. However, after several tests and finally disabling the secure startup option got the phone back to it's normal working condition. (Please note that I've not done a factory restore yet) Does anyone else have the same issue? is it a bug?

ZE551KL - Reboot on Setup / WiFi Connect

Good Day,
I'm trying to fix my brother's phone zenfone ze551kl
Initial issue: phone was rebooting on loading up to connect to wifi.
Factory reset was done via stock recovery & upon getting to set up page to select wifi, the phone reboots.
I tried updating via SD Card to latest MM firmware - UL-Z00T-WW-21.40.1220.2056-user & the issue still occured.
I then flashed TWRP via fastboot created a back2stock.zip with UL-Z00T-WW-1.17.40.1531-user & the same issue happened again.
Phone was never rooted & bootloader is still locked.
Any suggestions besides taking to service center would be appreciated as we do not live near any available & would be too costly to ship.
Try to search for an old raw of the ZenFone . I had the same issue with a ZenFone 2 ze551ml rebooting all the time that I tried to connect to Wi-Fi . I ended up flashing a really old raw and with the old raw it was able to connect to any Wi-Fi network without any issues. After that I I just update the phone without any issues
