WiFi issues since version 5.0

Hello,
Two months ago I upgraded my android version to 5.0.1, since then wifi problems start to appear.
There are two problems:
1) When the phone is sleeping, the wifi disconnect. once I wake the phone, even if it still locked, the wifi turns on again after 1 second. (I checked the advanced settings and "keep wifi on during sleep" is on "always").
2) Once I go from the wifi zone and come back after a while, I can't connect to the wifi. it just keep scanning, and when I tap on it to see available networks it just shows white page (switching wifi on and off doing nothing).
This problem can be solve by turning airplane mode on and off, but it only helps for one time - once I go away and come back to the same wifi zone I need to do it again.
*I tried factory reset, doesn't help.
*I flashed another rom, from HD revolution to ViperOne, and now my android version is 5.0.2, doesn't help.
*This problem happens in every router, not only in a specific one.
Maybe going back to the stock recovery will solve the problem, but I don't think so.
Thanks in advance

Your android version is software version but not firmware version. You can't update your firmware by flashing ROMs.
Post your fastboot getvar all (delete serial & imei no.) then maybe that getvar info will point to your actual problem.

Your radio low version suggest that you have a 3.x firmware installed, not 4.x which is required for 5.0.x android version.
Here is the latest RUU for your device version : http://dl3.htc.com.s3.amazonaws.com...G_20.68.4196.01_F_release_446501_signed_2.exe
Relock bootloader & run RUU.
Later you can re-unlock bootloader and install any custom ROM that you like

I'm pretty new to all this, so I'll be glad to have some explanation.
What's "ruu"? And how do I relock the bootloader?
What's the difference between Android version and firmware version?
I need to wipe something before I run ruu?
You think this is what cause the Wi-Fi problems?
Thank you!

Here is a good read for you : http://forum.xda-developers.com/showthread.php?p=52484527
relock bootloader - run command fastboot oem lock (after you put your device in bootloader/fastboot mode and connect to PC)
No need to wipe anything - the RUU will remove all and replace everything with the latest images - data, system, firmware and ROM
Your wifi problem as mentioned earlier because your firmware is old and has old radio baseband and not meet the minimum requirement for Android 5.0..x
An important note : after you done the RUU thing, to install custom ROM or to root, you need to install latest TWRP 2.8.7.0
Don't use the old TWRP recovery that you have .. as seen in your getvar all, there are a few missing info because of outdated TWRP

Ok the status changed to "relocked" instead of "unlocked", now just run the ruu? is there any command or something?
edit: I need to gain s-off first?
sorry for all the questions, I don't want to damage the device

It's harder to help when you ask all non-related stuff. I don't mention anything about S-Off because it is not necessary.
I know your device is S-on, that's why I said relock bootloader
Only two steps :
relock bootloader - run comman fastboot oem lock
run RUU - right click the RUU and select run as administrator on windows context menu
What you need :
USB2.0 on PC
Latest HTC USB driver installed - if not sure, download HTC Sync Manager - http://www.htc.com/us/support/software/htc-sync-manager.aspx
install it as it will install the latest driver then uninstall the HTC Sync Manager but leave the drivers.

RELOCKED is fine to run the RUU (as is LOCKED). UNLOCKED is the only status for that particular flag that prevents RUU.
You don't need s-off to RUU.

I relock the bootloader and run the ruu and now the wifi is working fine!
Thank you very much for your help!

Hi
I got the same wifi issue and I try exactly the same fix as #Avishay28 but they didn't work.

First - edit your post to remove serial & imei no.
Your baseband version suggest that you have a 3.xx.xxxx.x firmware installed.
You need a 4.xx.xxx.x firmware to have a working wifi when install a lollipop ROM.
What device that you have ? 0P6B16000 can be a Canadian device and some South American device. Update your firmware to the one meant for your device version.

My is Canadian device. I couldn't find a ruu version of device

There is no RUU available for Canadian device. At least tell what it is .. Rogers, Bell, Telus or ??? You can try to find a nandroid backup and stock recovery, restore then do OTA to update to the latest.
Or .. as your device is S-Off, you can change it WWE device i.e change MID to EU MID then install EU RUU.

As I mentioned above try find a backup for device.
You need 3.34.631.4 and its stock recovery.
I already switch off my PC and in bed. Not sure whether I have those files in my collection.
I'll check tomorrow when I have time but try to find it first. Should be available.

I'm having a problem being able to launch apps on my One M8 ATT... I Don't have any apps on my home page and ATT Ready2Go keeps crashing on me. Can someone give me a command line so I can launch SunShine on my device through ADB, that way I can S-Off and go back to a different ROM.

Why would you need s-off to install a different rom ?

The phone won't allow me to install anything through an RUU. Every RUU I've tried fails with a 155 Reason (Incorrect RUU) and shows "Loading zip file fail!" in the bootloader. A friend of mine has been working on it, got SunShine installed on the phone. But we want to run it to get the phone in to S-OFF. I'm not too savvy with ABD and that's what he's been using to talk to the phone. I also can't transfer items to the phone via USB even though I have drivers and MTP is running. The phone is a mess and I'm trying to avoid sending to HTC to restore it ($$$$$), or just telling my carrier that I "lost" it and pay the deductible to get a new one. Feels like I'm really close to fixing the phone, just not quite there yet.
If you know of a ROM I could try to flash, I'll give it a shot. I'm running out of options and time. Before I just get a new phone. My friend has helped me out a lot, but it's just not quite there yet.

You need to relock your bootloader in order to run an RUU while you are S-On.
In fastboot: fastboot oem lock
Then run the proper RUU again.
I'd link you to the proper RUU, but you haven't given enough info.
In fastboot: fastboot getvar all and post the results minus your IMEI and ser# (private information), unless you already know what the proper RUU to run is already.

The RUU you need can be found here.
Scroll down to the Manual System Update Instructions, and read them. The RUU download is at the end of the instructions.
You can unlock the bootloader again through HTCDev.com. After you are unlocked, flash TWRP from here in fastboot, then use that recovery to flash SuperSU from here.

I can NOT appreciate and thank you for your assistance in this! I went ahead and locked the bootloader and restored the original image with the RUU you linked me to, yesterday. Couldn't wait to try, haha. I had to sweet talk the HTC Live Chat person to tell me if I could use the RUU for the same software version as I had. Phone has been working like a champ. I'm gonna give it another day or two to settle in, do a few backups just in-case the flash doesn't go well.
I will definitely unlock the bootloader again and flash TWRP and SuperSU. But I imagine going S-OFF is just off the table right now since I'm a bit stripped of funds. I can afford it, haha, but my funds are already allocated towards adulting and such.
Again, THANK you for the support! This has been a learning experience.:good::good::good::good::good:

From AT&T to DEV via s-off. stuck on any RUU. sensor_hub.img error

Hello guys.
I've got a problem here. I have an AT&T One M9 unlocked phone.
Yesterday i installed twrp ,than root, than got s-off. That went smooth.
Changed mid
fastboot oem writemid 0PJA11000
than cid
fastboot oem writecid BS_US001 or fastboot oem writecid 11111111 (none helped, mean, it changed but still an error in update)
i was going to install dev edition RUU, so after that upgrade to MM from 5.1.
any RUU i've tried got stuck after flashing radio and 87% and that error bla bla(nothing helpful, no error code or something)
Okay i've got zip RUU and tried to flash via
htc_fastboot oem rebootRUU
htc_fastboot flash zip RUU.zip
or from latest android sdk fastboot.
Everytime i have the same error
....
(bootloader) [email protected]%
(bootloader) [email protected]%
(bootloader) ERR Flashing [sensor_hub.img] failed with status [255]
(bootloader) ERR Faild to update firmware [sensor_hub.img]
(bootloader) [email protected]
and after that only reboot helps.
any ideas? my guess that sensor_hub partition damaged somehow or maybe screen was changed on some non original?

From what i gather its a corrupt partition and only htc can fix it.
Beamed in by telepathy.

You can try flashing one of the firmware packages found in this thread: http://forum.xda-developers.com/one-m9/development/firmware-t3068243
Use the no wipe version as they won't wipe your system and data partitions (although I assume you have no OS since RUU is failing.
Even if sensor_hub fails to flash, you should still be able to install a recovery flashable rom (as in any of the roms in the development section).
You could also try this:
1) rename the RUU.zip to 0PJAIMG.zip
2) copy the RUU to the root of your EXTERNAL sdcard
3) reboot into download mode where you will be prompted to press volume up to flash or volume down to cancel - press volume up and let the process run
This method basically just eliminates the computer and the USB cable as the source of the issue. Although if the RUU always fails at the same spot, I suspect the computer and cable are not the issues.

Pretty easy, if you've already unlocked a bootloader on an HTC device before.
1) Backup any personal data you want to keep (to SD card, or off phone such as PC or cloud)
2) Unlock bootloader via HTCDev.com process
3) Flash TWRP 3.0.2 by fastboot per instructions found here: https://twrp.me/devices/htconem8gsm.html
4) Put ROM on SD card or phone's internal storage
5) Boot into TWRP
6) Do default wipe in TWRP (data, Dalvik, cache)
7) In TWRP, go to install, select the desired ROM
8) Reboot and drink beer

S-off is only needed for some specific things, such as changing CID/MID, manually flashing firmware or radio, flashing modified hboots, and some other things.
You don't need s-off to unlock the bootloader, flash ROMs, root, etc. Its not worth the $25 to s-off by sunshine for most folks, if the goal is simple to flash ROMs, root, etc.

That looks like a stock nandroid (stock ROM) in TWRP-restorable format. Its not applicable to what you want to do. Its also older than your current firmware version 6.12.401.4
Also, you don't need to fastboot oem lock, for what you want to do. You only need to reboot the bootloader if you are flashing an official RUU or signed firmware.zip. Relocking the bootloader at any point in the process will cause you major problems, as you can't flash custom recovery or custom ROMs with a locked bootloader.

RUU flash failed on T-Mobile HTC One M8. Relocked bootloader, Has OS, No recovery

So I've been trying to upgrade a T-Mobile HTC One M8 that was stuck on Lollipop to the official Marshmallow update RUU. However, when I downloaded the RUU and attempted to run it to flash the phone, it gave me Error 155, despite the fact that I had relocked the bootloader before I ran the RUU. No matter how many times I redownloaded the RUU.exe and ran it, it always gave me an Error 155. At this point, I do not know what is causing this to happen and I don't really know how to solve this issue. Help is appreciated!
I should add that the M8 was rooted and had TWRP installed before I tried running the RUU.
Where I got the RUU from: http://www.htc.com/us/support/rom-downloads.html

It also says "Loading zip info fail!" in the bootloader when I unplug the phone from my computer after the RUU flash fails.

There's a weird glitch with US versions that you have to flash the firmware before you run any 6.xx RUUs
Download this
Put it in your fastboot folder and:
fastboot oem rebootRUU
fastboot flash zip fw_6.20.531.5.zip
then run the RUU again

Thanks for your help! I was able to run the RUU after flashing the firmware. The M8 is now running smoothy with Android Marshmallow and Sense 7!
