does 4g works for you after unlocking sprint m8?Dont work for me in europe.Any solution????
[Sprint HTC One (M8)] androidlabs:
No 4g didn't worked for me either there is a gsm sign in a circle right next to signal bar when its light it means u r on 2g and when its dark it means 3g not 4g sign
[Sprint HTC One (M8)] PAKOS-:
cdma sucks.I love harman kardon m8 but i did effort to unlock it but now i am gonna sale tomorrow just cause of this reason.I will never ever buy cdma phone again.
[Sprint HTC One (M8)] androidlabs:
Yes i hate sprint phones too it was not my phone though i unlocked for my client and he was also dishearted after no 4g same like you :)
[Sprint HTC One (M8)] PAKOS-:
harman kardon is class thats why you can find very cheap on ebay because 4g dont work on it until you have cdma

---------- Post added at 12:22 AM ---------- Previous post was at 12:04 AM ----------

You have any idea if i buy at&t or t-mobile htc m8 does 4g work with them?Because at&t and t-mobile are not cdma.I want 32gb version and 32gb version only available in America.AT&T OR TMOBILE unlocked m8 worked in country ?
[Sprint HTC One (M8)] androidlabs:
All you need to do is to check full hardware sepcs and 4g frequency bands available on device and match them with your operator for example in Pakistan we have 3g working on 2100mhz frequency and 4g is working on 1800mhz so i have to match both with my phone secs if a phone have 2100mhz for 3g and 1800 for 4g that phone will work fine with 3g and 4g in my country otherwise no...
[Sprint HTC One (M8)] PAKOS-:
htc m8

It's just question that htc m8 at&t match the 4g frequencies with your country?And if only 4g frequency match with your country's 4g means only 4g will work out not 3g? Right?
[Sprint HTC One (M8)] androidlabs:
Yes but mostly phone have all frequency bands except sprint ones, do some research before buying google is the best teacher ;)
[Sprint HTC One (M8)] PAKOS-:
800 (band 20), 900 (band 8), 1800 (band 3), 2600 (band 7) MHz

Does these 4g frequencies match your country's frequencies?

and how you flash a s-on phone with lolipop to 4.4.4 ?, any one have a backup of 4.4 to recovery throw TWRP ?, i dont want to pay sunshine
[Sprint HTC One (M8)] JP07:
cant go back to lollipop

Hi, I just did it and everything went perfect! unlocked sprint m8 non HK, but I forgot to save my nandroid backup, Its possible to go back to lollipop without my backup??? I'm stuck on 4.4.4.
[Sprint HTC One (M8)] arturgig:
The at&t and t-mobile models work with almost all GSM frequencies, including 4g lte on many countries.

---------- Post added at 06:39 PM ---------- Previous post was at 06:38 PM ----------

You can relock your bootloader then take the OTA, if your rom is stock official

---------- Post added at 06:44 PM ---------- Previous post was at 06:39 PM ----------

This sim unlock works for international use only. Cricket uses at&t frequencies so I highly doubt it will work.
[Sprint HTC One (M8)] JP07:
Error message when relock

Thanks, but when I tried to re-lock with FASTBOOT OEM LOCK I got an error message and stuck on bootloop only could get to fastboot, not even recovery, had to unlock again. Can you give me another method to re-lock??
[Sprint HTC One (M8)] arturgig:
It happened to me once, and I had to do it all over again, install RUU lollipop, unlock bootloader, flash recovery, superuser, make a backup and do all the steps again
[Sprint HTC One (M8)] JP07:
How can I install a RUU if im stuck on fastboot boot and relocked, is that possible??
[Sprint HTC One (M8)] arturgig:
Well if you no longer have recovery Im afraid thats your only option, if you see relock with or wihtout security warning go ahead and install the RUU.

HK phone with 4.4.4

Hey guys!

I managed to "unlock" the phone, at least it now accept Sim card (shows "Sim services"), but it doesn't hook up to the carrier network!

And I can't switch from CDMA to GSM mode (It says "No sim found. Switching back to CDMA"), no matter from what menu I try to do that. It also says "GSM serive - Radio off".

How do I turn "

Radio on

"?

Hope someone can help

My specs:

S-On

Unlocked on InsertCoin 3.0.4, and then switch back and forth from stock 4.4.4 (from recovery) and installing Insertcoin over and over again, but it always says "radio off"...
[Sprint HTC One (M8)] Tekone:
Have you tried this step? 8. If you see you that you have no network then dial *#*#4636#*#*. A menu will pop up. Select phone information then scroll down until you see 'select preferred network type'. I believe it only pop up on Kitkit, not on Lollipop.

Also, is this phone activated on Sprint yet?
[Sprint HTC One (M8)] mrMMMichail:
Thanks for reply!

Sure I have. It says "radio off" and it won't let me switch to any other type of network but CDMA/LTE bla-bla-bla.

In that very menu (at the bottom) there're buttons "Update", and when I hit it it actually detects the correct sim number!

I assume, in order to make the phone hook up to my carrier network, I have to activate radio. But I have no idea how to.

Nope, the phone isn't activated on Sprint. It's is not in the US, so I can't activate it anyhow.
[Sprint HTC One (M8)] CrashVegas:
has it been done by anyone?

Has anyone actually sim unlocked it? Is this sim unlock only for outside the US? I've unlocked over a dozen phones and htis is my first one that i cant sim unlock. Does anyone have a harmon kardon edition they can take a pic off and show a carrier other then sprint on the notification bar.
[Sprint HTC One (M8)] mrMMMichail:
Still no luck with mine, have tried almost every single tutorial.

Looks like the only way out is to s-off the phone and activate it the other way.
[Sprint HTC One (M8)] CrashVegas:
What other way? lol i havent done the S-off method but am curious as to where that guide is thanks. Also do you know if this is to unlock it for us or for outside of us. I also called a company that all they do is flash ad unlock and even they said its a no go.

Thanks
[Sprint HTC One (M8)] arturgig:
Hi, I've unlocked like 5 htc's, the HK version and normal , its the same. I think this only works for international use. Follow my guide and you shouldn't have any problems
[Sprint HTC One (M8)] Tekone:
This method for international sim unlock. Domestic sim unlock, we may need s-off or feather unlock somethings.

I have done with method, and pop in T-mobile or AT&T sim card will shows invalid sim. Pop in international sim card in without shows invalid sim.
[Sprint HTC One (M8)] mrMMMichail:
Hey!

Well, I'm outside the US, and the phone doesn't say "invalid card", but can't hook up to carrier's network for some reason.

I think the problem is VDM client...

Now the phone is on Lollipop, but radio is still "off".
[Sprint HTC One (M8)] arturgig:
Yeah I had a similar problem with a phone. I recomend you flashing a different ROM based on 4.4.2 or less. And also flashing again the SIMLOCK exploit.
[Sprint HTC One (M8)] mrMMMichail:
I'm playing with it for almost 2 months.

Maybe you have a link to the ROMs I should try?

Thanks!
[Sprint HTC One (M8)] arturgig:
Barebones is the one I always use.
[Sprint HTC One (M8)] mrMMMichail:
Thanks for reply!

Which version? Seems like the latest one is 2.1.

You might have the old one based on 4.4.2, right?

It'd also be one more fix if you could upload it somewhere so others could download and flash it.

Thanks!
[Sprint HTC One (M8)] mrMMMichail:
Hey guys, I got some new info.

In settings, about the phone, I had "account name" ###@vzw3g.com which is Verizon account! How's that possible to have another carrier's settings if the phone isn't unlocked?! Then I reset it by going to "activate the phone", ofcourse it failed and I selected "reset" (top right corner), then the phone rebooted and I saw ###@sprint account. Haven't tested the unlock method yet.
[Sprint HTC One (M8)] ecobio30:
I have tried to unlock it but every time that I use Terminal Emulator I cannot go beyond the am start com.redbend.vdmc/com.htc.omadm.test.TestMainActivity. It says that it cannot be found. I have a Sprint HTC One M8 HK running stock-rooted 4.4.4. What am I doing wrong?
[Sprint HTC One (M8)] jeffamorim:
i've done almost every possible Unlock method with no sucess.

All the Unlocks are only to International GSM?

I've tried to make my M8 Non-HK work on H2O with no sucess, but if it works when i get back to Brazil, maybe it is worth to keep the phone.

Does anyone have any ideas of what to do next?

After unlocking the sim in HTC one m8 which type of firmware can be flashed? Should it be sprint firmware or any developer edition firmware???:confused::confused::confused:

Sprint firmware only. Other firmware will cause soft brick.

Hey!

What "badboys.zip" are you talking about? Please share it with us.

The unlock is permanent once you manage to unlock it.

[HTC One Max] RyanH77:
Hi all.. Quick question.

I've just started the process of trying to root my One Max (international) and everything has gone smoothly with unlocking the bootloader etc, and i've flashed a CWM image to it as my recovery, but once i've rebooted, volume down and select recovery, hit power, it says entering recovery but then screen goes off, waits about 20-30 seconds and boots up as normal.. Is the CWM image file wrong? And if so, can i just redo the process of flashing the rom again the same way, or do i need to uninstall this image before i can? Does any new image not just overwrite?

I'm just a little frustrated at this point because it's now unlocked and tampered yet i have no root access.
[HTC One Max] cstrife999:
Go with twrp it roots the device after first time going through the recovery. I've heard of issued with cwm.
[HTC One Max] RyanH77:
The reason i picked CWM over TWRP was because i'm familiar with it and like the UI.. TWRP just seems too basic looking. But my initial question still remains. Can i simply re-run the process over the top with TWRP or do i need to remove CWM before i can write TWRP to the device?
[HTC One Max] cstrife999:
I would highly suggest twrp either way though yea always just flash over in fastboot.
[HTC One Max] RyanH77:
Ok well i'll give TWRP a go. But do i need a specific .img file? Because when i go onto the TWRP site to get the version i need, it only lists Sprint and Verizon for the One Max. I'm on International so surely need a GSM or Non-US variant surely? Or can i just use the M7 GSM version?

Thanks.
[HTC One Max] RyanH77:
Ok, now i've just redone this procedure exactly the same but with TWRP instead of CWM and it's doing exactly the same thing.. Why does it just go blank after saying "entering recovery" then boot as normal after about 20 secs? I really want root access but can't see how i'm going to get it if my phone won't boot into recovery.
[HTC One Max] RyanH77:
Ok.. I finally figured what was wrong.. The .img was too new a version and clearly my phone didn't like it.. So i used an older version and it's done the whole process perfectly. So to anyone else having the same problem, try an older version.
[HTC One Max] RyanH77:
Ok, hang on.. It seems i might not be rooted.. I've installed TWRP, done my Nandroid backup installed Superuser and a few root checkers and one of them said i was rooted, while the others couldn't gain access, same with Superuser and SuperSU, they both say they can't access binaries etc.. Now i assumed once the phone said tampered, unlocked and had TWRP installed that it was rooted.. Is this the case? I have attached some thumbnails of various screengrabs so someone can tell me if i am or if something has gone wrong.. When i did it on my DHD it was never this hard to root..

Updated to OxygenOS this morning. I did a full factory reset before flashing. I signed in to my Google account, everything synced except my contacts. It says they're synced in the settings app, but in the dialer and contacts app, there's nothing. I was able to sync my work Exchange account and everything came down fine. When I go to contacts and select Accounts, I only see my exchange account, no option to even add a Google account for syncing. Does anyone know what's going on?

Also rather annoying, AdFree does not seem to actually be working, even though it says it's installed the latest host file.

I'm mad I didn't make a backup before wiping like I always do. I always back up my SMS messages too, and I forgot to do that :crying:
[ONE Q&A, Help & Troubleshooting] :
Working fine here. Something on your end.
[ONE Q&A, Help & Troubleshooting] beano311:
Solution

I figured out that it's because I flashed an incompatible version of gapps. It said it was a lollipop version, but it may have been for 5.1. I'm used to ROMs not coming with gapps, but then I remembered that Oxygen is certified and doesn't need a separate flash. All the other Google apps seemed to be working fine, but I guess one or more of the services weren't fully compatible.
