Hello guys,
I have problems with the mobile internet, and wifi connectivity. I noticed that the mobile internet, or wifi loses connection ("freezes"). It still shows that it is connected but nothing is happening when trying to load a page, I have to turn off and on the mobile net / wifi to get it working again.
I was guessing that I could update the radio if there's any update.
Some data about the phone:
ROM: Viper 8.0.0
Hboot: 1.57 S-Off
Firmware: 7.19.401..2
Kernel: ElementalX 20.1
Radio: 4T.35.3218.16_10.33Q.1718.01L
The phone is not carrier locked and has superCID.
Can you please help, if there is an update for the Radio? I mostly found radios starting with 4A. ....

you should update your firmware. Hboot 1.57 means you are probably on a 6.xx.xxx.x firmware. Newer roms need 7.xx.xxx.x firmware.

not done properly as @alray said, 7xxxxx firmware comes with HBOOT 1.61 and your still on 1.57 which is KitKat firmware, and that's also the reason for your wifi issues, its a common problem running Lollipop roms on KitKat firmware.
flash the 7.19.401.2 firmware, don't forget to flash it twice, and then flash the 7.19.401.22 firmware, if you are s-on then you will need to relock the bootloader, if your s-off then no need to relock, you will then have to unlock the bootloader and reflash your custom recovery before trying to boot your phone, neither will wipe your phone.
7.19.401.2 is here: https://www.androidfilehost.com/?fid=23991606952612380

Definitely, sorry my error. I mistyped the hboot. It is 1.61 not 1.57.
Firmware is 7.19.401.2
I guess I can try .22 firmware. Does is contain a newer radio? I'm S-off so won't be a big deal updating.
Thanks for the help.

I thinks its just a radio and recovery update if I remember correctly, always best to be on the latest firmware.
EDIT: just checked, its boot, radio and recovery update.

Did you apply the Sense 6 OTA to your phone? If you did, then the hboot is a higher number than the RUU you are trying to re-install. The same thing happen to me and I had to install a lower hboot. Check @nkk71 SuperGUIDE to returning 100% back to stock for instructions on how to do install a lower hboot.

I need to restore my phone to a version of stock android (either an actual stock RUU or Android Revolution or whatever) so that I can get to the UICC option to turn off my SIM card (this setting is not available in CyanogenMod apparently).
Because I am on a newer firmware and because I am S-ON I do not seem to be able to install any of the (mostly older) RUUs I have found. Any suggestions? Is there an RUU for 4.06.651.9 that I am not seeing? Is there another way to roll back my OS to allow an older RUU to be installed? Another option altogether? A way to S-OFF while on CM?
Thanks for your help

Is this the 3.04.651.2 RUU? If so, I already have a copy, and when I attempt to run the ARUwizard I get Error 155. Most likely I am doing something wrong. I just assumed that since I am already on 4.06.651.9 that the problem was I couldn't install the older 3.04.651.2 version. Thoughts?

This is exactly the same issue I'm experiencing. Well, now I'm even beyond this point... I am only able to boot the phone to the bootloader.
Edit: I am relocked as I am S-ON. I can't update firmware as the signature check fails. Flashing the 3.04.651.2 zip has a signature verify fail, as well.
Hope this helps

If you can still boot to bootloader your phone is fine. You should still have recovery (TWRP?) on your phone I assume. Regardless here are some steps that should help:
1. Figure out if you are S-ON (is found on the bootloader screen)
2. If you are S-ON, try Rumrunner to get S-OFF (just google it). This will allow you to install any RUU regardless of your firmware.
3. If Rumrunner doesn't work or you don't want to go to S-OFF then download the 4.06 RUU here http://forum.xda-developers.com/showthread.php?t=2658910
The problem is your firmware is ahead of the corresponding firmware of the 3.X release. As such you have to install from the newer RUU.

Actually, it seems that the phone is wiped; I can't boot my recovery. As a result, I can't really get S-OFF. I'll try the 4.06 RUU, but would it make a difference that it's .4 and not .9?
EDIT: I'm talking out of my ass right now. Long day, and this isn't helping. I am figuring it out; unlocked the bootloader, and now things seem to be functional. Well, except CM doesn't seem to want to boot any longer, but that shouldn't matter for long.
EDIT 2: How can I get S-OFF without enabling debugging? As of right now, CM is just in a boot loop.
Sim Unlock Sprint HTC One Max
I almost cannot believe how many different ROMs I've tried to flash after wiping out my original ROM.
Bootloader unlocked and rooted I managaged to relock the bootloader while trying to fastboot flash a stock ROM, which also failed.
Beleive it or not, I've have found a couple that will boot up with my Sprint HTC One Max . I was able to re-unlock the bootloader, flash a new rom and even recover user data I had backed up to my PC via adb backup.
All this for not, as I still cannot find a Sense ROM that will flash on my device and allow me to unnlock the Sim via Sim Unlock Helper.
Any help would be greatly appreciated!!!

Hi,
I want to send my HTC One in for repair, so first I need to restore it to stock.
However, I recently updated my firmware (and hboot) to the new 4.4.3 base (http://forum.xda-developers.com/showthread.php?t=2793539) so right now I am (s-off) on hboot 1.57.0000... Is this a problem when sending it in since this firmware isn't officially released yet (or is it)? And if it is, is it possible to downgrade my hboot?
Also, must I flash the firmware WITH the red warning before going S-on and locking the bootloader again?
I have flashed the stock odexed ROM, boot.img and recovery from the ARHD site (http://android-revolution-hd.blogspot.nl/p/android-revolution-hd-mirror-site-var.html).
Thanks in advance for any help!
No that firmware isn't officially released yet, it's still in testing stages so you will have to downgrade your firmware to 5.??.401.? Lucky for you this firmware comes with hboot 1.57 however if you have flashed a modded hboot/firmware ie to remove red text, then you will need to flash an official one, just find the official firmware package and use that, it comes with the hboot inside it, if you s-on with modded firmware or hboot you will have an instant brick.
The arhd site your got the Rom from should have the firmware package too.

Great, thanks! I will flash the original firmware in a sec, but the most recent RUU I can find is this one: http://www.htc1guru.com/dld/ruu_m7_...0-38r-1157-04l_release_353069_signed_2-1-exe/
And I am not sure if that is also based on hboot 1.57 and because of that, if I am able to flash this RUU. Currently I am downloading it but the download speed is terrible, I will report back after I tried.
Or are you saying that I can flash the stock firmware 5.xx.401.xx on top of the current 6.xx firmware? I thought that wouldn't be possible because I'm currently on a higher firmware version but I'll give it a shot!
If you are s-off, you can flash or downgrade anything, however I would personally flash the matching firmware to the ruu that you are downloading, however, the firmware and hboot will be included in the ruu and be downgraded when you run the ruu, so just run it, once it's finished and you boot the phone, you can ota up to the latest version.

You may have to remove the TAMPERED flag before running the ruu and also lock your bootloader, not relocked as the ruu will replace which ever recovery you ha e on your phone for the stock one, sometimes the ruu requires a locked bootloader whether s-off or s-on.
Once it's finished, boot the phone once and then back into bootloader and check the hboot version, if it is lower than the version you have on there now then you'll know you have stock hboot and should be safe to s-on, however like I said before, make sure your locked and tampered has gone before setting s-on (not sure if s-on is required for warranty)

At the moment I don't have a tampered flag, it only says 'unlocked'. I'll try to lock the bootloader before starting the RUU. Do you know if the Tampered flag will return if I S-ON my M7 after completing the RUU?

Unfortunately I don't know that, there's been some reports it comes back after you s-on not after the ruu, I think it's HTC 's way of catching you out, others say it's been fine, are you sending it to HTC or your operator ?
---------- Post added at 04:14 PM ---------- Previous post was at 04:12 PM ----------
However , if you've had s-off with that phone before, chances are you'll get it again, you'll just have to do whatever you did before to get it, then go back to stock again, and send it s-off.

considering you are s-off,
very little, but even with s-off, you will first need to downgrade hboot to same or lower version than the signed ruu.exe/ruu.zip
on the other hand, a decrypted ruu.zip doesn't have that restriction

So my process will be...
1. Downgrade hboot to 1.44
2. Change back my cid to HTC__002 (when i flashed the RUU from the GPE i changed it to GOOGL001)
3. Flash the RUU zip
Is that right?

you don't have to go back to hboot 1.44
If your RUU is 4.xx flash a 3.xx firmware first
or 3.xx RUU a 3.xx or 2.xx firmware will work.
you may also need the MID change tool if you changed it also

The 1.28.401.7 is Jelly Bean it's equal to a 3.xx.xxx.x RUU
So the Firmware you would want is this http://xda7.androidrevolution.org/db_mirror/Firmware/HTC/HTC_One/401/2.24.401.8.zip
Hi guys,
I have soft bricked my device and currently the only way I see out of this is to flash RUU but then my version is way too high than the RUU available on the internet I've gone through. My current version is 4.20.707.7 but so far I've only found 1.29.707.3 the highest RUU version available on the internet.I have SuperCID but device is currently relocked and S-ON. I tried flashing other region's RUU which has higher version than mine believing the fact that I can flash it because I have SuperCID but I failed and received an error 155 which I searched and it means I'm using the wrong RUU. So I guess I can't flash other region's RUU and have to stick with my current region's.
Question:
1) Is it possible to flash the same version of RUU with the device?
2) Is it possible to flash other region's RUU if I have S-OFF? If yes, I only have access to fastboot and recovery and as far as I know, you only can S-OFF with a working homescreen, so how do I S-OFF while I only have access to fastboot and recovery?
If yes, does anyone have RUU for version 4.20.707.7 ( my current version ) or above?
If no, does anyone have RUU for version above 4.20.707.7?
Please help. Replies are much appreciated. Thank you And sorry for the tiny misleading information on the title. My current version is 4.20.707.7 not 4.20.707.6.

My current version is 4.20.707.7 but so far I've only found 1.29.707.3 the highest RUU version available on the internet.I have SuperCID but device is currently relocked and S-ON. I tried flashing other region's RUU which has higher version than mine believing the fact that I can flash it because I have SuperCID but I failed and received an error 155 which I searched and it means I'm using the wrong RUU. So I guess I can't flash other region's RUU and have to stick with my current region's.
Question:
1) Is it possible to flash the same version of RUU with the device?
2) Is it possible to flash other region's RUU if I have S-OFF? If yes, I only have access to fastboot and recovery and as far as I know, you only can S-OFF with a working homescreen, so how do I S-OFF while I only have access to fastboot and recovery?

Yes, with s-on you can flash same or newer ruu version to your phone as long that it match your MID/CID + Firmware base (x.xx.707.x)
Yes you can flash other region RUU if s-off. You might need to change your CID and MID which can be done from fastboot (CID) and from recovery (MID). You can flash a close to stock rom like arhd to achieve s-off.
If yes, does anyone have RUU for version 4.20.707.7 ( my current version ) or above?
If no, does anyone have RUU for version above 4.20.707.7?

Many option for you.
You can restore the 4.20.707.7 version using the 4.20.707.7 stock reset rom (to be flashed in custom recovery)
You can flash the 7.21.707.5 ruu but in order to do that, your phone firmware must be at least 6.xx.707.x or 7.xx.707.x so it will requires to flash one of these firmware before the ruu.
Honestly I would simply flash the 4.20.707.7 reset rom, simple to do. When installing the rom, select "yes" to stock recovery and radio. Select "no" for root. when flashed, take all ota updates until you are on latest (7.21.707.5). From there you can flash a custom recovery and root if you want and returning back to stock from this point (if something else happen) will be as simple as flashing the 7.21.707.5 ruu.

Hey man, thanks for the useful information. I flashed the 4.20.707.7 reset ROM and did what you have told me but then the problem in the end is still the same as flashing other ROMs ( custom and stock ). The problem will be after unlocking the screen, green HTC logo appears and stays there for quite some time while dialer keeps crashing from time to time, and after few minutes, reboots by itself. This cycle will go on forever. Any advice ? Thanks again bro.

Looks like an hardware problem. Is your phone still having an IMEI # when doing "fastboot getvar all" ?
