wi-fi not working on M8

Hello,
I want to buy a second hand HTC M8 and it has a issue with wi-fi.. it won't turn on or connect to wi-fi. from the screen shots i see that it has network (3g network). the guy selling the m8 says that a friend of his tried to put a custom rom on the phone and after that the wifi stopped working. here are the printscreens send by him. could you tell me if i can repair it myself or it is the wi-fi chip damaged.

Wifi doesn't work because the ROM is 4.4.4 but device is still 4.4.2
(can see this from the baseband version)
You can easily fix this by put in correct ROM version

can it be done without s-off? with a ruu.exe?

This s the bootloader

No need S-Off.

You better remove the 3rd pic where it shows the IMEI no. & Serial No. Those are sensitive data.
Anyway ... checked your IMEI, it is a EU version, so there is a RUU available which you can directly update it to the latest Lollipop version 4.16.401.10

thanks. will remove those pictures. i will but it tonight.

Is it for a good price due to WiFi not working? If so, the devil on my right shoulder says it serves them right for modding the phone without doing the proper research! Or researching properly to (easily) fix the problem, for that matter.

the price is ok. my old htc m7 + 100 euro

Help me to get it stock please !!

Remove serial no. in your post
I'll write simple guide on how to get back on stock and update to the latest lollipop when I'm home in next 3 - 4 hrs (if no one attend to this yet)

i see that the phone has Vodap001 CID but the soft on it (rooted one) is for the HTC_00x CID.. problem? i have got a stock backup, unzipped it, putted in TWRP backup folder, now i restore it and after that flash the stock recovery?? is that all?

It's a Vodafone UK M8, but still easy restored to stock
To be honest, I'd get it back to 1.54.161.x using the backups @ckpv5 will post, S-OFF with Sunshine and then convert it to the unbranded handset using the 4.16.401.10 RUU (using the guide in my signature)

skirmish please .. one m7 i could do it with no problem but this guy kills me

Can't write proper guide as I'm driving....
Follow this guide : http://forum.xda-developers.com/showpost.php?p=59034701&postcount=4
But don't use that 3.29.161.9, you need to restore 1.54.161.10 and its recovery then proceed multiple OTA up to lollipop 4.19.161.2
You can get the needed files here : http://forum.xda-developers.com/showpost.php?p=58606328&postcount=4278
Note : if you have plan to S-Off your device, do it after restore 1.54.161.10
if you want to keep it S-On, just proceed OTA. Later you can install any custom lollipop ROM if you want to

you could follow my guide on the viperone thread , steps 1 to 6 would get you onto stock android lollipop with a stock recovery , just do a full setup at step 6 , my guide proceeds past this point to then install a custom recovery and a custom rom but if you stop at step 6 after setting up the phone you will be unbranded stock
hope this helps

First ... remove the serial no. & imei no in your post as they are sensitive info.
You have 3 options :
1. Restore 4.16.401.10 TWRP backup - http://forum.xda-developers.com/showpost.php?p=60147089&postcount=5104
It read as WWE 4.20.401.10 TWRP Backup but that's typo error .. it should read as WWE 4.19.401.10 TWRP Backup
or
2. Relock your bootloader and install 4.16.401.10 RUU.exe - http://forum.xda-developers.com/showpost.php?p=56140330&postcount=1
(make backup of your internal storage important data as this will wipe everything)
or
3. Relock your bootloader and fastboot flash the 4.16.401.10 RUU.zip - http://forum.xda-developers.com/showthread.php?t=2735235
(make backup of your internal storage important data as this will wipe everything and also note you need htc_fastboot instead of normal fastboot)

thanks for your fast response.

Read the thread linked in my signature on how to restore a TWRP backup.
You need to extract it with 7-zip and put those files in your backup folder not to ADB it nor fastboot it.

hi guys
I have similar problem.

software number was 4.16.401.10 before OTA update.
can i also use the files above to try to fix the phone?

Thank you. restore is in progress.
After restore i will flash back stock recovery and then relock the bootloader.
If i do that, my top line in bootloader will disappear ? right now is : "Software status: Modified "

No need to relock bootloader.
Only when running RUU.exe or RUU.zip you need to relock bootloader when S-On.
Using a backup no need to relock bootloader. Just flash stock recovery then do OTA.
If that backup fails (as I'm not sure whether that's fully stock or not), I put up my own stock backup in my thread .. you can try that later if current one fails.

Restore successfully completed. Now, in order not to have problems with latest OTA , i have to restore stock recovery, right ?

Are you sure that you started installing OTA after flashing stock recovery ?

Yes. OTA downloaded and I tried twice to install, but all it did was restart phone into bootloader.
After flashing stock recovery, I rebooted phone, ran OTA and update started.
After update completed, phone rebooted to white start screen with HTC logo and froze there.
I have read that this is probably because I ran OTA on rooted device.
So now i am stuck with no OS and hope these files will help.
Thanks ckpv5 for help and link.

stock nandroid restore worked. got my phone back
flashed stock recovery and running OTA again now. fingers crossed.
but whatever happens, just wanna say thanks again guys. much appreciated.

if I may ask, what is the safest method to run OTA in future?

i dont really know. Anyway , how about your free space. i dont know what happened because now i have less that 1 GB free space.

Boot the custom recovery and make a pure stock backup. Restore that one if you need to ota update again

The best solution for me if I ever have this problem .. I will format data (not wipe data) in TWRP before I restore the backup (of course need to backup internal storage data somewhere else first)

Done . Now i have free space. many thanks !!

Can't get my m8 to boot anymore

I used to have a custom rom on my phone but I tried to wipe it and im not sure what happened but I don't think there's an OS on there anymore. It gets stuck on the HTC white screen. I am able to access fastboot and I have TWRP recovery installed that I'm able to access, but I believe it's an older version. I tried just downloading another rom and flashing it but it still wont boot. I'm not sure what I need to get it working again.

Yes your Firmware is the version-main and its empty, thats crappy.
First download this TWRP Stock Nandroid Backup: https://mega.nz/#!mYxDWApA!JbdLZAhYkz8fas5MpPfOQqGScikCLCmG21KBsjRJKQQ
Then use latest twrp recovery 3.0.2-0: https://dl.twrp.me/m8/twrp-3.0.2-0-m8.img.html and install it.
Here is the Stock Recovery that you need later: https://mega.nz/#!SUATBBbQ!-IUlr_tqnpkYFUM0bedRSRH3w__nCZjEAYls-5zncX4.
Then do this taken from this page: http://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860.
The basic idea is : fastboot flash recovery NameOfRecovery.img
2. Download TWRP backup - link in post #2 & post #3
3. Download stock recovery - link in post #4
4. Extract the downloaded x.xx.xxx.x_ckpv5.zip on PC
5. Boot to TWRP recovery and make a backup of boot only, this is to see where the backup goes on your device.
6(a). Reboot, connect device to PC then
open Internal Storage - TWRP/BACKUPS/SerialNo./ (if backup is set to internal storage)
open SD Card - TWRP/BACKUPS/SerialNo./ (if backup is set to MicroSD)
6(b). For those with no OS, connect device to PC. In TWRP recovery go to mount, make sure MTP is enabled.
Then you can open Internal Storage - TWRP/BACKUPS/SerialNo./ (if backup is set to internal storage)
7. Transfer the extracted x.xx.xxx.x folder (not x.xx.xxx.x_ckpv5 folder) and its content to the backup path on your device, so it looks like this :
TWRP/BACKUPS/SerialNo./x.xx.xxx.x
8. Reboot to TWRP, wipe your device - in TWRP go to wipe - advance - select dalvik cache, cache, data, system (only these)
9. Restore the transferred backup - make sure all boot, data & system are ticked - swipe to restore
10. In reboot menu select bootloader (when TWRP asks whether you want to root your device, select do not install)
11. fastboot flash stock recovery that you downloaded - command fastboot flash recovery x.xxx.xx.x_recovery.img
12. reboot - check for OTA, download, install
13. you may have multiple OTA when your device currently on a lower version
14. done
If you want to flash TWRP again, use the latest TWRP after last OTA
NOTE : There is no need to relock bootloader when doing the nandroid way to revert to stock and do OTA.

You won't be able to run current ROMs because your firmware is too low version.
What you can do is run the latest RUU to get back to stock at Marshmallow firmware then reinstall TWRP to install any custom ROM that you like
1. You need these drivers - http://forum.xda-developers.com/showpost.php?p=64926362&postcount=4
2. You need to relock bootloader because your device is S-On, use command
fastboot oem lock
fastboot reboot-bootloader
3. You need to install htc signed 6.20.531.5 firmware
Download :
https://mega.nz/#!yIhBTRKJ!5rZldUEzCaFqYUhomn4mO_IgA_-nW6-gV9HX5LCzT5Y
run commands
fastboot oem rebootRUU
fastboot flash zip fw_6.20.531.5.zip
you'll see error : FAILED
repeat fastboot flash zip fw_6.20.531.5.zip
fastboot reboot-bootloader
4. You need to install the latest 6.20.531.5 RUU
Download : http://www.htc.com/us/support/htc-one-m8-t-mobile/news/
right click the RUU.exe and select run as administrator, follow the instructions - agree/accept, next,next,update,blablabla until it finish.
Now you'll have a out of the box state device.
You can unlock the bootloader again with the unlock_code.bin
Re install TWRP - use the latest TWRP 3.0.2-0
You can install any custom ROM that you like.
All the above procedure require you to put the device on bootloader/fastboot mode and connect to PC.
The above procedure will wipe everything in your device including internal storage data/files (if you want to backup first, install TWRP 2.8.1.0 and in recovery you can enable MTP after connect to PC to copy out files from Internal storage)
All these require you to have a Windows PC with USB2.0

Hboot 3.16 means OP is on 1.xx firmware.
Which also means the nandroid and stock recovery you suggested are off by 3 versions (4.xx). Are you guessing at the version number?
ckpv5 has the best route. RUU will update the firmware, and get the phone back up and running.

4. You need to install the latest 6.20.531.5 RUU
Download : http://www.htc.com/us/support/htc-one-m8-t-mobile/news/
right click the RUU.exe and select run as administrator, follow the instructions - agree/accept, next,next,update,blablabla until it finish.
Now you'll have a out of the box state device.
You can unlock the bootloader again with the unlock_code.bin
Re install TWRP - use the latest TWRP 3.0.2-0
You can install any custom ROM that you like.
All the above procedure require you to put the device on bootloader/fastboot mode and connect to PC.
The above procedure will wipe everything in your device including internal storage data/files (if you want to backup first, install TWRP 2.8.1.0 and in recovery you can enable MTP after connect to PC to copy out files from Internal storage)
All these require you to have a Windows PC with USB2.0

Thanks for this information. I had tried to revert back to stock using that exact RUU from the HTC website but it would keep failing and I didn't know why. Using the stock firmware steps you included got it work. I appreciate the help.

If you had posted the RUU failure symptoms (Error number and message, if there was one; specific behavior and results, etc.) we could have helped there (and still be happy to, if you are at all curious about getting RUU to work). But it looks like you sorted it without RUU, anyway.

Restoring by RUU versus nandroid are two completely different things, and you should be careful not to confuse the two:
RUU re-writes all partitions, including firmware, so there is no chance of a mismatch between firmware and ROM. Therefore, you don't need to match the RUU version to firmware, as long as the RUU is equal or greater number than the current firmware on the phone (no "downgrading" with s-on). And with s-off, this requirement is removed entirely, so you can run any version RUU that matches your CID, MID.
Restoring by nandroid is a completely different animal. Nandroid just contains the ROM and kernel. It needs to match the firmware on the phone, otherwise it won't work properly.

I understand his post differently .. he managed to run RUU after firmware is flashed, a step his missed before (a needed step to run a MM RUU on lower firmware, but never told earlier).

Now I understand. Its confusing, since the 2 methods (both of which have you to credit) to return to stock are both referenced in this thread (another user references the nandroid method); and folks often use the term "firmware" incorrectly to refer to the ROM.
It also means that the user did not follow your instructions in Post #5 in the proper sequence. So RUU failing was inevitable, and easily avoidable; if they had followed your instructions in the proper order.

You flashed a rom that wouldn't work on Sprint device by default. You need proper kernel to run with this ROM but I will not go further on this.
Your best bet now is install RUU meant for Sprint.
Everything that you need is here : http://forum.xda-developers.com/showthread.php?t=2729173

Thnks for your reply sir , i was trying to do this , but now my phone cannot connect to the RUU installation wizard , How can i do it

I'm not on PC .. unable to write proper guide.
The easier one for you is download 0P6BIMG_Sprint_HTC_One_M8_4.25.651.14_RUU.zip
then rename it to 0P6BIMG.zip and put it on your microSD, not in any folder.
On bootloader, press power once to go to hboot. Once on hboot it will scan the file and ask whether to update. Volume up to update and let it do its stuff. Once completed, reboot.
After setup complete, delete that zip file.
Before that, if you select to go to recovery, do you still have TWRP ?
If yes, boot to recovery and make backup of your internal storage as the above procedure will wipe everything on your device except microSD.
Or you can install any ROM with sprint support (like the one I'm using now) then you don't need RUU.
After completed and ROM is booting, you can install any other ROM with Sprint support.
But it's best for you to update your firmware to Marshmallow first.

thnks a lot , i'm going to do this steps seems easy ,
the last part that i didn't get , how can i update my firmware to marshmallow first ?

ckpv5 , got the ruu file and rename it and copy it to sdcard , but when i go into HBoot it says
Image Update Fail
Parsing ...
Device Halted due to large Image Update Fail
press power to rebbot .

You downloaded the one that I mentioned ? I made a mistake there (wrong file copied).
You need the one that have 4.25.654.14 in it, sorry.
When I said update to Marshmallow first, that's after you fixed current problem.
After you successfully installed 4.25.654.14, then do OTA to 4.25.654.18 then later to 6.20.654.3
(That's why I don't like to help when not on PC.. sometime copy wrong filename)

Soft Bricked M8 in need of help badly

Hi there in need of some help. I have really ****ed up my install of twrp and supersu from my htc one m8.
I followed this person tutorial htconeroot com/htc-one-root I followed everything to the letter apart from enabling Dev enable usb debugging.
1st of all I downloaded this twrp file "openrecovery-twrp-2.7.0.2-m8" when I should have downloaded the latest version of twrp. Such a noob mistake I know now : (
2nd I also downloaded a older version of supersu SuperSU-v2.79-201612051815 which I loaded onto my phone and should have downlaoded the latest version.
I followed all the instruction on the video and when I rebooted after instaling supersu my device is now stuck on the HTC startup screen.
I tried to reboot again going into fastboot and recovery and nothing worked. I know I should have just updated supersu to the latest version but I followed some other peoples advice and now I have completelty screwd my phone I think.
I deleted supersu from twrp and wiped the files as well. My computer now does not recognise my phone folder to be able to install any updated version of supersu or install a ROM. My computer OS is windows 10 and it now sees my phone as a cd drive so cannot install anything on the drive at all.
I can get into twrp but nothing seems to work when I try to reset back to factory settings.
Is there a command line way in geting back into my phone and being able to sort this mess that I have made.
In need of some serious help from the experts here at xda developers.
All help is very much appreciated.
Thanks Steve

These random "root" websites just copy content from XDA, and have little or no community to help you. All you need is on XDA, so I recommend stick to XDA.
Such "root" websites also don't give enough information, aren't well organized, and don't update it all. So they are very likely to get you into trouble, as you now know.

What version, if it wasn't SuperSU 2.79?
What version of Android was the phone on when you started? Was it Marshmallow?

There is really no such thing as "reset back to factory settings" especially in TWRP. Just going in and wiping things, isn't going to fix the problem.
Try to fastboot flash an updated version of TWRP. If you were on Marshmallow, try current version 3.1.0-0 from there: https://dl.twrp.me/m8/
Once booted into TWRP, see if you can access the internal storage from your PC. If not, make sure internal storage is checked in "Mount".

Sorry was this version SuperSU-v2.37.zip. I do appologise thats the latest version that I posted and was ment to be this version SuperSU-v2.37.zip this is the one that I installed.
Yes it was marshmallow.
I downloaded the latest version of twrp and can I ask how to re install twrp ??
I cannot access my phone internal storage for some reason my computer is not recognising my phone now. It was before as I installed supersu straight onto my phone internal storage and tried to boot the phone from that. It's now coming up as a cd drive and I cannot access to install anything on it.
In mount all I have
System >>> not checked
cache >>> not checked
Data >>> is checked
Micro SDcard >> is checked
USB-OTG >>> not checked
Thanks again for your help

Flash with fastboot. Which I would assume is the same way you did it before. Instructions on TWRP's website: https://twrp.me/devices/htconem8gsm.html

Let's get the right version of TWRP on the phone first, and see if that helps. If not, we'll go from there.

Updated twrp
Hi just to let you know that I have booted into the new twrp. I am using FWUL and using simple-ADB and it installed it no problem.
Just cannot seem to find how to install supersu onto my device as my phone is not showing up FWUL OS.

Sorry, what is FWUL?

Updatefor you
Hi just to say that I installed supersu as well the latest version SuperSU-v2.79-201612051815. After rebooting I am back to the htc page. I have no ROM installed at all on this and it's saying there no OS installed on my phone.
I want to install kali Linux Nethunter and I have downlaod the correct files to install.
WillI have to install another OS like Marshmallow or kitkat before installing Kali Nethunter.
Thanks again for yourhelp : ))

[LIVE-ISO][FWUL][STABLE] adb/fastboot without any installation and driver issues

Did you not send me there to download it lol : ))

You must have at some point in trying to "fix" the problem, wiped system in TWRP. System is same as ROM/OS. So if you wiped it, it's pretty obvious that no ROM is the result.
Flashing old SuperSU in itself doesn't result in no ROM/no OS. It just makes the phone stuck on boot screen, and flashing the proper SuperSU will fix it.

I've never used it. But reading the thread, it looks like you need a fully working OS. So pick a ROM, put it on the phone, and flash it. Then flash Kali Nethunter.

Ah, I see it's listed as one of the several options for adb/fastboot in the TWRP install instructions. I've never used that specific one, so the acronym confused me. Any fastboot/adb environment will work about the same. You didn't really need to install anything new on your computer. You already had fastboot on your computer to begin with (to unlock the bootloader), and that would have worked fine to install TWRP.

BackUp File
Hi there and thanks very much for your help very much appreciated. Before I did everything I made a back up and have the files on my desktop they are:
0C77AEECE8C258113148C6FB487946BF97B34672
01C669ECF50A775226B15B9F60EEB522AB34BE2F
I have ten of these files and a deafault file as well. Can I restore these to my hpne at all.
I am going to try and install marshmallow on my phone as that was the last OS that I had. Do I have to have the most current and updated version MM.

What did you use to "backup" the phone? Those don't look like TWRP backup folder names. They look like MD5 verification codes?
Individual TWRP backup folders will usually have name format of the date/time the backup was made, such as: 2017-04-22-20-43-56....

There weren't many different official versions (maybe 1 or 2) of Marshmallow for each M8 carrier version. Any version MM should do.
