[Q] HTC M8 Wifi problems on several Roms -HELP!

I was hoping someone could help me with a problem I have.
My htc M8 was rooted and insertcoin was flashed onto it however the wifi button greyed out and wouldnt turn on in order to s-off it. I tried several different roms and they all have the same problem. I am currently running skydragon v5. I have been trying to sort this phone out for a week and I am getting absolutely nowhere so any help would be appreciated. It's on ORANG001 and is s-on.
Thanks

You have old firmware. You need to have 4.19.61.2 on ORANG001 in order to have wifi on these ROM.
And you post this in wrong section.

Apologies, new to the forum it's been moved now!

Yeah .. requested it to be moved to correct section.
So .. you need to restore your stock ROM and do OTA up to 4.19.61.2
What's your current firmware version .. 3.33.61.9 or 2.26.61.1 ? Or even lower ?
Check what's written on bootloader - hboot 3.16 or 3.18 .. you need 3.19

Hboot is 3.16.0.0000
The phone is currently in the bootloader and I can't get it to turn on to check the firmware version.

That's a very low version ... you need to restore to stock backup 1.54.61.5
But I deleted my TWRP backup for most 1.xx.xxx.x only keep 2.x; 3x & 4x
There is someone else backup made with Philz recovery so you need to download Philz recovery - http://forum.xda-developers.com/showthread.php?t=2703223
then download the backup : https://mega.co.nz/#!WhwRmSoJ!QJxmI0gYj7t_0Hc4fMKx0XLYQ2n45S3OfrEcDRS3C-s
restore that backup with the stock recovery (included in that backup if I'm not wrong)
then do multiple OTA

I was trying to adb push the firmware to my phone to then install it on Recovery but when im typing "adb devices" it says list of devices attached then it is blank. I have been trying to search for solutions but I cant seem to fix it. If you have any advice it would be much appreciated. Thanks

Has anyone got an idea?

This is usually an issue on the computer's side (PC?). Try to re-install HTC drivers, try another USB port, or another cable. Also, if you have USB 3.0, this is known to cause issues with adb connectivity (apparently, you can disable this).
Also, you need to be booted into OS or in recovery for adb to work (does not work in bootloader) and you need to have USB debugging activated in Settings.
And when you say "firmware" I think you mean a nandroid backup, based on the instructions previously given to you? Be careful using the term "firmware" here, as most folks use that term to specifically mean the firmware.zip that contains hboot, radio etc. (but not ROM).

Don't you have a MicroSD ? Put the extracted nandroid on MicroSD at the right location clockworkmod\backups\ is easier than doing that ADB push.

Okay finally got the nandroid backup installed. Then when i tried to install the OTA update it took me to CWM and failed. So i then relocked and tried again to update OTA and it took me to the bootloader with a ***Relocked*** and *** Security Warning*** any ideas ?

You need to re-install the stock recovery in order to OTA. Bootloader lock has nothing to do with it (will OTA with unlocked bootloader).

I have installed the Nandroid backup mentioned above to stock i believe. Is this the correct step or is this still not stock ? it was 1.54.61.5
Thanks

Stock ROM backup and stock recovery are two different things.
You need to fastboot flash recovery recovery.img to replace the CWM that you have now. Inside the backup zip, there is a recovery.img .. take this out and fastboot flash it.
You need to unlock bootloader to flash it.

when using the command "fastboot flash recovery recovery.img" using the recovery.img from the unzipped nandroid folder the process runs and it says okay with no errors then when i try go into recovery the red triangle and exclamation mark appear again

Yes that's stock recovery. Perform the ota now

Because that is stock recovery. You don't need to get into recovery.
Just reboot, check OTA, download then select install.
Let the system do the installation on its own

First question is, are you on stock ROM or not (unlocked/relocked/all stock ?!) ?
Please tell us what you did before and how you did the OTA or even give some more info at all

If you didn't do anything to the phone, i would say the best idea would be to send it back for repair if you still have warranty on it... (any other way of fixing it by yourself would maybe void your warranty)

Warranty is over and i am in a remote town in uae, so sending to repair is the last option.
where can i get stock rom or RUU for my phone version.

ok read trough here: http://forum.xda-developers.com/htc-one-m8/general/guide-restore-european-htc-one-m8-to-t3072235
Best would be if you read every page because the guy at the last page hast the same CID like you (could be helpfull infos for you)
But BEFORE you start trying this method (or the method mentioned at the end with nandriod backups) you first have to unlock your bootloader (wich voids your warranty)

As you mentioned your warranty is over and you don't need to send your phone for repair.
What you need to do :
1. unlock bootloader thru http://www.htcdev.com/bootloader
2. install TWRP 2.8.7.0
3. restore Marshmallow 6.14.707.1 non-rooted backup
4. don't accept root offered by TWRP
5. install stock 6.14.707.1 recovery.img (optional)
6. reboot & done.
All files & How-To, see : http://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860
This will get you back to your stock ROM
Or you can unlock bootloader, install TWRP and install any custom ROM that you like to try.

I did the following instead already:
1. unlock bootloader thru http://www.htcdev.com/bootloader
2. install TWRP 2.8.7.0
3. Root using TWRP
4. ?
Can u ley me know the next step now. Can i use the twrp backup from the below post now ?
http://forum.xda-developers.com/showpost.php?p=60211240&postcount=3
Thanks for your simple and step by step process.
You guys rock.

Yes ... 6.14.707.1 backup on post #3 & 6.14.707.1 stock recovery on post #4
For all the steps, read post #1 ... I don't want to repeat them here.

hey all, great to see this post and i have exact identical situation here and want to try the step here to fix my M8. rashmixda, do you successfully revive your m8?
p/s: sorry that i edit the post twice to correct the name i ask and a typo. realize i asking wrong person after i saw the backup file name after ckpv5. thanks for your backup and it is my life saver for my M8.

Help: Cannot turn on wifi/bluetooth. Phone no longer have cellular signal.
Hi ckpv5,
I followed this guide and I was somehow able to revive my phone. Before, it no longer boots --it goes straight to the bootloader after the HTC logo. Unfortunately, my wifi, bluetooth, and cellular signal issues have remained unresolved -- I still can't turn on wifi and bluetooth and I still don't have cellular signal) . Before my phone went into bootloop, I already had these issues and they have persisted until now.
Is there a chance that these are just due to a software/firmware issue? And if so, please advise on what to do to resolve these issues. Thanks in advance for your help. My phone is not supported in my country. In fact, it was returned to me by the authorized service center unrepaired after a month of being with them.

I don't know whether the problem is hardware issue. Based on your info, it looks like hardware problem.
What you can try is restore one version lower 4.19.707.4 backup and install 4.19.707.4 stock recovery then do OTA again to 6.14.707.1. When doing this, it will reinstall the firmware too and see whether this will fix your problem.

Hi ckpv5,
Thanks a lot. I am now downloading the files.
I'll be probably be doing the OTA update manually since I cannot turn wifi on on my phone. Can I use the 6.14.707.1_ckpv5.zip file that I previously downloaded? Or probably I have to root my phone so that I can share my pc's internet to it through reverse tethering. Will rooting not cause issues during OTA updates. Thanks...

As I wrote above, you need to restore 4.19.707.4 and its stock recovery. Don't use 6.14.707.1 and don't root.
After you restore 4.19.707.4 you can connect to PC and use Internet Pass-Through feature to check and download OTA .. don't root because OTA will fail on a rooted ROM. We expect the OTA from 4.19.707.4 to 6.14.707.1 will fix your problem. If it does not fix it, then it is hardware problem.
Note : you can't manually install OTA on a S-On device

Anyway, i just try to restore version 4.19.707.1 with recovery and let it upgrade with OTA as this is 2nd way to restore my M8 with latest OS. now, quite confirmed it fixed and no more random reboot for pass 5 hours. usually reboot happened 3 to 4 times in an hour. the detail about finding the cause will be posted on my thread.
thanks again for valuable help.

Marshmallow OTA failed

Hi All,
I'd like a bit of advice/help.
I went to update my phone to Marshmallow OTA and it did it's thing. I left the phone for hours and it appeared to be stuck on android is starting. I restarted the phone and it's now stuck on the HTC splash screen. Recovery options don't work etc.
I've searched around and there are loads of guides but these tend to lean towards rooting. I'm not looking to root but instead looking to get the phone back to factory software that it was originally on.
It's a UK model locked to the 3 network. See below for info taken from the phone.

Can anyone assist? I'm desperate here. I've not had a working phone for days here. The guides I've seen appear to apply to either previously rooted phones or suggest I get the file from the HTC us site but my software versions is newer than those listed.
I have HTC tool kit installed and android studio so any tips would be greatly appreciated.
Thanks.

Is the bootloader UNLOCKED ? or LOCKED or RELOCKED ?
If it is UNLOCKED, I can suggest to restore a non-rooted stock backup.
If it is LOCKED, you can try going to recovery and do data wipe from there (provided that is stock recovery)
and don't use Toolkit .. it brings more harm for less experience user

I've managed to unlock the boot loader. How do restore using a non rooted standard backup? Thanks for replying.

1. You need these files adb/fastboot and HTC USB drivers installed
Read this for the files : http://forum.xda-developers.com/showpost.php?p=64926362&postcount=4
2. Read this thread post #1 on How-To restore a backup and install stock recovery
http://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860
3. Install TWRP 3.0.0.1 - https://dl.twrp.me/m8/
4. Download and restore 6.13.771.4 backup (from post #3 from link on no.2)
5. Download and install 6.13.771.4 stock recovery (from post #4 link on no.2)
6. Reboot and see whether it works or not

Thanks for that.
It's now at the stage where the apps have been optimized and it's now just hanging at the "Android is starting..." "Starting Apps...".
This was my original issue I had when the software was updated first time round.
Any clues on how to get past that?
Thanks

No clues ... hopefully it's not hardware problem.
What you can try .. restore one version lower, then do OTA becuase OTA will reinstall the firmware.
Restore 4.25.771.6 backup & its recovery.img then check for OTA, download and install.

The downgrade worked and I updated to Marshmallow but for some reason, the phone still hangs on Android is upgrading and starting apps. I'm at a loss as to what to do next. I don't want to use a phone on an old version of software and never upgrade.

So you can boot the lollipop but not Marshmallow ?
I don't know whether you can find htc signed 6.13.771.4 firmware.zip .. this is the only thing I have in mind. Maybe manually flashing the firmware.zip will fix your problem.
I'm already in bed as I will be outstation in the morning. If you can wait, just run the lollipop for the time being. I will give you the firmware.zip on Sunday night (GMT +8) to try to fix it.
Hopefully someone else will be able to help you while I'm not around.

Would changing the CID and MID and selecting a different software package work perhaps?

You only can change CID & MID on a S-Off device.
To S-Off your device you need to pay usd25 for the Sunshine app.
Why don't you try a Marsmallow custom ROM to see whether you can boot it.
If you can at least you can run a Marshmallow ROM until you fix your problem.
I'm signing off now .. goodnight & good luck

Thanks, if anyone else could assist that would be appreciated. I've installed a custom marshmallow rom and all went well but it still suffers with the same fault. It hangs on starting apps. No matter what I do this phone doesn't like Marshmallow!

Hi, I'll wait for your offer of the firmware zip and try that. For some reason this phone doesn't like anything to do with marshmallow.

Sure can .. I get back to you once I'm back from outstation tomorrow evening.
1. Restore the Marshmallow 6.13.771.4 backup if you're on different ROM
2. Download firmware.zip
3. Put your device on bootloader/fastboot mode and put the firmware.zip in your fastboot/adb folder and open a command prompt from this folder
4. Run below commands
fastboot oem lock - to relock your bootloader because your device is S-On
fastboot reboot-bootloader
fastboot oem rebootRUU
fastboot flash zip firmware.zip
You'll see -
if failed : FAILED (remote: 90 hboot pre-update! please flush image again immediately)
repeat fastboot flash zip firmware.zip
fastboot reboot
check whether your wifi is working now ..

Thanks for that, what I did in the mean time was use the sunshine app to S-Off and change my CID and MID to a deveolper phone. All was fine until the phone upgraded to marshmallow. It still hangs on the Android is upgrading starting apps. It seems no matter what I do this phone will not accept marshmallow.
Any other ideas as to why? So odd why marshmallow doesnt boot past this screen.

Since now your device is S-Off .. instead of updating it to Marshmallow, have you tried running a Marshmallow RUU on it ?
(Assuming your current firmware installed is 6.12.1540.4)
Here is the RUU : http://www.htc.com/us/support/htc-one-m8/news/
If after running the RUU and still the same problem .. I have to say that I'm out of idea.

I'm downloading one now. I'll update you with the outcome. I'm at a loss as to why this is happening. What does the RRU contain?

It has every images that a device need. Means it removes everything on your device and replace them with new images that come from the RUU.
One thing to note, other that those drivers and HTC USB Drivers that you need (in my previous post), you need a PC with USB2.0

It's currently optimizing apps so we'll see if it boots up. Is there much difference between doing an OTA through all the various updates and going straight via an RRU?

Sadly, it still does the same thing. Would a hardware fault possibly cause this?

My HTC M8 developed random reboot after a failed factory reset

My HTC M8 run into problem since after failed to upgrade to marshmallow via OTA. It was stuck at HTC logo but manage to revive after follow instructions at http://forum.xda-developers.com/htc-one-m8/help/htc-one-m8-htc044-stuck-htc-logo-ota-t3303043 as i have the same exact model in post. I follow everything except flash back stock recovery image which is optional as suggested in post. I kept TWRP just in case it bricked again. Yes, i do relocked the bootloader and it is all fine.
After few weeks for good running, i come to the point that i need restore it from my previous backup. So,i do a factory reset from HTC settings. It reset and rebooted but nothing nothing change. Then, i try to go recovery mode but just it just reboot. Then, i suspect it is the relocked cause the reset cant complete as not possible to get into recovery mode. So, i do unlocked again and reboot to recovery and it does continue the factory reset but failed with message "openrecovery script failed". So, i just use the TWRP to reset and all goes well again but random reboot happened. sometime happen in few mins, sometime hours.
i tried to restore it again as the steps i revive from bricked but random reboot still there. Even restore the stock recovery and relocked and reset again and random reboot still happened. I'm really completely no idea what to do fix it. move to custom rom? Root it and fix the write permission problem? Please guide me what i can do next. I just need to get it back to working condition regardless what rom as long as stable. thank you.

You can certainly try a custom ROM. Its not any more invasive that what you've already done. Just unlock the bootloader again (leave it unlock - more on this later), flash TWRP (even if its still installed, it looks like it has some issues and can use a fresh install) and flash a custom ROM.
In any case, don't worry about relocking the bootloader, its not doing you any favors; and just creating more steps for yourself. Relocked bootloader is only needed to flash RUU or stock firmware (not required for OTA or anything else you are doing).

[Solved] random reboot on my M8
Thanks redpoint73 and ckpv5, i quite confirmed that i just manage to fix my random reboot problem. the solution i do the the alternative way to unbricked M8 on the same post at http://forum.xda-developers.com/showpost.php?p=66274104&postcount=18.
Anyway, here i would like to add more finding about my problem which i has spent this few weeks to observed. the problem that i has is actually corrupted radio baseband. there are few hints i get indicating my M8 having radio based problem.
1. in M8, go to settings > About > Software information > More. there you will see all OS related info and baseband version but my baseband version showed "Unknown" instead of 1.29.214500021_2G.
2. then, back to About and go to Phone identity. there i suppose can see my IMEI and IMEI SV but in my case also showed "Unknown".
3. whenever after the M8 rebooted, it will ask to send error Report to HTC. there you can get to page where it shows the M8 detail and also the Log. just tap on Log and it will open up the error log first. there is where i get to know my problem is in the radio baseband. at almost end of stock, there is 1 log like reboot-reason=modem-crash and something like "oem-98". both also indication radio or modem has problem. this is where i think i should fix the baseband problem and guess it will fix this random reboot problem.
after restore the 1 version earlier stock rom and recovery and upgrade via OTA and not radio baseband is fix and first 2 item above can be view at about page now.
i hope my sharing can help others and avoid go through so much of hassle and time to figure out what's wrong.

Htc one m8 bricked?!?! Stuck on boot screen (htc logo)!

Hi guys I have an HTC ONE M8 running 4.4.4 with TWRP and Root installed and a few weeks ago I tried to go into TWRP and clear cache and dalvik-cache and such, as usual. When I did that and rebooted the phone, the phone is stuck on the HTC logo and I can only boot into bootloader mode and also into TWRP. Also TWRP is also saying I have lost root access.
What can I do to fix this problem can I restore back to 4.4.4 as a new device and re-root it and install TWRP? How do I get out of this mess? It is S-ON and Software Status is MODIFIED.
No matter how long I leave the phone it will stay on the logo until it dies or until I boot into bootloader.
Thank You Guys I Have Lost Hope Honestly.
IF ANYONE CAN HELP ME PLEASE PROVIDE THOROUGH INSTRUCTIONS! THANK YOU!

First of all, the fact the screen comes on at all, means it almost certainly not bricked, and recoverable. You just can't boot into OS, and with TWRP installed, that is not too serious a problem.
On the other hand, once you have TWRP installed, the first thing you should always do before rooting or other mods, is to use TWRP make a backup of system and boot.img. And even after successful root, it's good to make a backup of the rooted ROM. If you had a TWRP backup o the phone, in an event like this (no boot into OS) you can simply boot into TWRP, and restore the backup.
If you have no backups, you can download the proper one from the collection: https://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860
You can then restore using the instructions from that same thread. You only need to do steps 4-9 to get the phone running again, then reboot. Steps 1-3 relate to installing TWRP (which you already have). Steps 10 and on, are optional as they will install stock recovery to the phone, which will allow you to update to more current Android version (which will eventually get you up to Marshmallow).
If you need help determining what version number TWRP backup to restore from the above linked collection, then do fastboot getvar all, and post the results (delete IMEI and serial number before posting).
Another option is to RUU back to stock (if your version M8 has an RUU) if you are okay with the phone being wiped. If you are s-on, you will need to relock the bootloader in order to RUU. Then after RUU, unlock the bootloader again, install TWRP and root the phone.

What does it say next to "OS" in your bootloader?
Also, if you can boot to recovery you should be able to restore a backup

There is no OS installed at all for some reason! When I try to download a backup I need to flash it and the only way to do so is by having the MTP Driver installed in order to drag it into TWRP and flash the backup. I can't do so because it fails to install my MTP Driver.

you can use a card reader to put the rom or the backup on external sd card
or use an OTG USB flash memory
also connect the device to pc while you are in recovery this should work by it self no need to install MTP driver
which OS you have on your pc ??

No OS is usually an easy fix. Download a ROM on your PC, put it onto your extSD, and flash the ROM in recovery. The reason you have no OS is because you wiped system in TWRP. If you do that, you need to flash a ROM after or you'll have no OS on a reboot.
It's best to never wipe system in TWRP as this is done by default in recovery when you flash a ROM. There will be the odd instance that it is suggested to wipe it ( I've never seen that with HTC based ROMs), but if it isn't then don't.

Not clear which drivers you are trying to install, the HTC drivers from their website, the ones which load from the phone, built-in Windows drivers, etc.?
Try going to HTC's website, and download HTC Sync, which will also install the drivers. If you already have this installed, try uninstalling, and re-install.
Alternately, the Android MTP device drivers built-in to Windows is a generic version of drivers which can often get at least adb/fastboot working, and probably also allow you to drag/drop to internal storage in TWRP. If these drivers are the ones failing to install, it would imply there is something wrong with your Windows installation (which there isn't a lot we can help you with) rather than anything with the phone.

How did you pick a nanddroid backup to download, if you don't know the OS number?
Do fastboot getvar all, and post the results (delete IMEI and serial number before posting).
Also, what version TWRP?

You need to be more specific:
What version number of file name of the RUU you tried? Zip format or exe format? If zip format, did you flash by fastboot, or SD card method?
Did you get an error message, if so, what did it say exactly? If no error message, what was the mode of failure (what happened exactly - be detailed - at what exact point did the RUU fail, status of the phone, etc.)? Saying "It didn't work" doesn't give us any info to troubleshoot why it failed, or how to get it to work.
Also, you did not provide all the info requested (questions I asked you in my last response):

You need to flash the firmware 6.20.651.3 in order for the RUU to install (firmware and RUU are different things - so don't confuse the two). The firmware and how to flash are described here (as well as all the Sprint RUUs): https://forum.xda-developers.com/showthread.php?t=2729173
Just a heads up, if you don't know already: No need to relock the bootloader to do this (flash either firmware or RUU) since you are s-off, and no benefit in doing so. Plus, relocked bootloader gives you less options to recovery, so it is not recommended to relock it in your case.
Also, in regards to your original question (no boot after restoring TWRP backup): you never answered my question of how you picked a TWRP backup to download and restore (which I asked twice before). Now that I see you have the Sprint version M8, I will guess that you tried to restore the incorrect version backup. Sprint version uses different kernel from most other M8 versions. So if you don't restore the proper one, no boot is the expected outcome. Also, even if Sprint, it would have to be the same version you were on before (Kitkat) which is another reason it would not boot.
