RESOLVED
I was flashing the zip with flashgordon zip flasher after root..I guess it don't work
I also rooted a method with some Chinese program..it rooted but I guess differently..
After rooting with method I was able to install cwm fine after updating such binary..then flashed the radio and had signal... Unlocked BL last night
Ive flashed from wind mobile 21d(Canada) to tmobile 10g to 20b(Europe open) to try and unlock bootloader..
I get no radio signal at all after switching to 20b.. I tried flashing the radio.zip from the noobs guide(put in sd folder) thread..as he did in his youtube to repair signal after flash..however it did not bring back my radio...
I have read working signal is needed and important to ul bootloader on 20b and I cant seem to get the radio working
ive heard I need to swap radio..which I did(flashed the radio.zip) from his files( after I rooted and confirmed root on 20b)
still no signal..

Trying to use GSM, what did i do wrong?

Hi again people, ok so here's the deal. I have this Moto Photon that was running on 2.3.4, so i decided to give it a try to the GSM methods by flashing the KDDI radio. First i unlocked the bootloader, then i rooted the phone using AIO, flashed CWM recovery via fastboot and backed up the stock ROM. Everything went fine till that point, but then when i flashed the KDDI radio and flashed the Peetrs rom it looked like everything went well. Except for the fact that when the phone booted was asking for activation. It wont let me pass that message with the onscreen keypad so now i dont know what to do in order to make that work. Please i need some help asap...

Unlock Bootloader lgl9 p769 21d (wind mbile/canada)

Hello i have just purchased this phone and i want to unlock the bootloader and install CWM and then Cyanogenmod but im finding it is very difficult to do so.. I have a few questions.. i have found some info on here but it says from tmobile 10g..which i am not.http://forum.xda-developers.com/showthread.php?t=2277639. Why is it so hard to do this and why after so much time has an easy fast method not been posted anywhere.It pisses me off they lock this thing up with all this built in bloat and make this so hard for users.. we are paying for the phones-therefore we should have 100 percent control over how they are used..
1. Is there any easier less risky way to unlock my bootloader and install cwm/cyanogenmod than this clusterfack way
(http://forum.xda-developers.com/showthread.php?t=2277639) for noobs ha
2. I rooted and flashed Cwm but i cannot get into it either with key combo or adb reboot recovery(brings me to android with open stomach screen, thats it..and i assume if i try to flash a zip like cyanogenmod IF I DID GET IN WITH A LOCKED bootloader it wouldnt work or id get security error)
i have busybox installed and phone is fully rooted..I need to avoid bricking and security errors at all costs
3.i need detailed step by step instructions for lg l9 p769 21d (locked bootloader) willing to offer a bit of cash to anyone who can help me successfully Unlock my Bootloader without any device brickage or security errors.
Update: Itried installing the artas test version on cwm with his installer and I now can get into cwm..the stable one wasn'tworking..
So now Ihave recovery just bbootloader locked preventing me from flashing any new ROMs...sighh
Update..I used cwm recovery installer by artas and I now can get into cwm
Device info
lg l9 p769 21d (android 4.1.2)

1.) Flash to 10G. T-Mobile doesn't matter, it still works with Wind. I've used Wind ROMs on my T-Mobile.
2.) That is the only way to unlock it, I'm sorry. Some conspiratist was trying to unlock it using a different method, but he rage quit when someone made fun of his website (lol).
3.) Really, it just takes luck. I haven't got it yet. But I try daily and it takes about 20 mins of work and 30-40 mins of waiting, so it's worth it. About to give up though lol.
LOL, I just realized you used numbers too. My numbers here don't correspond to your questions in that order. What a coincidence!

OK flash from 21d wind too T-Mobile 10g... Then I need to flash to Europe open 20b for 760...unlock the boot loader with mirrored image and messed up touch screen..then gain root..install cwm and fix the touch screen..
ARE YOU SURE I CANT GO FROM 21d to EUROPE 20b? Unlock bootloader and root and then Be done with it?And if so , Why not?
Anyone here unlocked boot loader of 769? BTW there is no working link to Europe open 20b kdz..I've been looking everywhere for an hour all links and downloads are broken/not working..anyone have the Europe open 20b for this process?
edit think i found the europe 20b
People say there's problems with it lol.. I haven't unlocked yet sadly. It's an annoying process and I feel that some devices can't be unlocked no matter what

Well it can be unlocked..but its a pain..day 1 and lg support tool will not install w admin priv/compatibility mode for xp sp 2/3.I'm on win 7
I take it this is why it won't flash the kdz and crashes the kdz installer..also shows phone not found in emergency mode but it is found in diag mode..what's with that?
Lol.. I'll try again tomorrow.. But I think I need to on a diff PC cause I've tried everything and it just gets stuck(lg support tool) at like 10 percent install..
What is the reason for going from 10g to 20b Europe and then back to 10g
Why not just stay on 20b fix the touchscreen etc and leave it..?
What issues if any would arise from flashing 20b Europe from 21d wind?
The unlock boot loader for.noobs 769 has files for SD including radio.zip..
Does the radio not work after flashing 20b Europe open? And if so how can I flash a zip on Europe 20b and unlock the boot loader without first installing radio.zip through a cwm?

[Q] ¿Can i take an OTA whit S-OFF?

(SOLVED)
Im in stock 4.1.2 whit S-OFF, unlocked bootloader (1.55) and then RELOCKED.
¿Can i take the last OTA?
Im not rooted, and i dont have custom recoverys (i recently flashed a RUU.zip to return to stock, but i could not remove the S-OFF and RELOCKED status because the hboot 1.55).
I have economic (health) problems and I'll really need to sell my phone, but I'm afraid that the new owner will come out error when trying to update.

Yes. You can get OTAs while S-OFF. And assuming you haven't unlocked the bootloader since flashing the RUU, all the system files it verifies should be in place to accept OTAs. However, considering you are currently on 4.1.2, you'll need to run through a progression of OTAs to get up to the latest version, 4.4.2 w/ Sense 6. Might be better to just run the latest RUU to bring it up to 4.4.2 w/ Sense 5.5 then OTA to Sense 6. Be aware that you'll need to be on the AT&T network in order to get the updates OTA. If you're not on AT&T, you'll need to flash the updates manually, in which case you'll need to be S_OFF.
Also, once the phone is S-OFF there is no good reason to change that back to S-ON. There's the potential of bricking the phone by doing so. And even if it doesn't brick, the updates in firmware may make it more difficult to obtain S-OFF again.
Thank you very much.
At the begining i did this:
1- Unlocked bootloader and flashed TWRP.
2- Root
3- Gained S-Off
When i decide to sell it i did this:
1- Removed xposed and root.
2 - Relocked bootloader.
3 - Flashed RUU.zip (4.1.2)
¿What do you mean whit AT&T network? I unlocked the phone vía imei (using it in mexico whit Telcel) and still have the update appearing.
Sorry for my terrible english

First off, since you are S-OFF there is no need to relock the bootloader in order to flash an RUU. It will run just fine with an unlocked bootloader. Also when you flash an RUU, all the partitions get wiped so there is no need to do anything within the ROM such as remove xposed & root prior to flashing. The RUU will set the device essentially in a factory state.
As far as I understand it, the OTAs for carrier specific devices are served up by the carrier. So if the phone has been SIM unlocked and is being used on another network, if you go into Settings>AT&T software update, it will not receive any available OTA update. You will need to flash the update file manually using the information in this thread, http://forum.xda-developers.com/showthread.php?t=2659374.
Since you are still on 4.1.2, you will need to run one of the recent RUUs in order to manually flash the OTA updates in that thread. The latest RUU available for AT&T devices is KK4.4.2 w/Sense 5.5.
http://androidruu.com/getdownload.p...09_10.26.1718.01L_release_356565_signed_2.exe
Flash that then you can manually flash the OTA update to get Sense 6.
You are the man.
THANK YOU SO MUCH!

[Q] Help!! Wifi Issues after installing Viper on AT&T HTC M8

This are all steps that I have tried and nothing works:
1. Install twrp 2.7.0.2 succesfully, then viper. (no wifi)
2. flash ruu for att, install twrp 2.7.0.2 succesfully, the viper. (no wifi)
3. flash ruu for att, install twrp 2.8.6.0, twrp recovery won't load, stuck on screen
I've read in some threads that wifi issues are because of old firmware, but I installed latest rue and didn't solve anything, and for some reason twrp 2.6.8.0 which says is for all carriers won't work in my phone. Also tried installing ARHD rom and it doesn't work either. Is there any file I need to flash for wifi to work or what are the specific steps I need to follow for it to work correctly. I did this in another HTC M8 for Sprint and had no issues at all. I appreciate your help.
*** I managed to flash 4.4.2 custom kitkat rom. Wifi works in this one. How do I go from this one to Viper M8 without messing the wifi up? In the page it says to upgrade to 5.0.1 before but how do I even do that? Not sure what I'm supposed to flash before installing Viper or where to find it. Do I also need to update TWRP before? Thanks.
Did you try the Viper thread?
Haven't found detailed instructions yet. I managed to flash a stock rom for 4.4.2 for at&t. But when I searched on the phone for an ota update to 5.0.1 it didn't find any. Then I flashed viper again but wifi didn't work. I guess I have to install stock 4.4.2 again, the install a stock update to 5.0.1 and then flash viper. I'll try this option later to see if it finally works. Have been working on this for the past 3 days.
What RUU did you run?
Did you relock the bootloader to run the RUU (required since you are s-on)?
Your hboot indicates you are still on 4.4.2 firmware, which is why WiFi is broken on 5.0 (Lollipop) ROMs. You either ran the wrong RUU, or the RUU failed to install due to unlocked bootloader.
Easiest way to update the firmware is to relock the bootloader and run the AT&T Lollipop RUU.
I downloaded ann RUU zip file for version 4.4.2 and just placed it in sdcard and asked for uptade automaticaly. I don't have the AT&T sim card, which I guess is the reason why I press software update and it says that the phone is up to date. The two ruu I found for lollipop, one says european version and the other is .exe which won't work on a mac. I really don't know if a lollipop ruu zip file of the US version even exists or if installing the European version is the same thing or if my only option is OTA update with a sim card
Finally got it to work. Long process but I'll explain what I did for anyone with the same problem. Thanks for the help everyone.
* I downloaded RUU.exe from one of the threads
* Used parallels on mac ( download free trial of software and windows 7)
* First enabled show hidden files on windows
* went to C> users> (USERNAME)> APP DATA> LOCAL > temp> (open folder just created, one with a really long list of letters)> copy rom.zip from there to mac 1.6gb file
*rename to OP6bimg.zip
* copy to sd card root
* open bootloader > hboot
* it should automatically ask to complete update, just press volume up button and it should work just fine
* now you should be in stock lollipop.
(I havrn't rooted yet, but I guess now I won't have any wifi issues when flashing custom rom)

That means you are on 4.4.2 firmware. So you if you try to run any more recent version based ROMs (4.4.3, 4.4.4, 5.0, etc.) you will have broken WiFi. You need to run the 5.0 RUU to fix this.

That is correct. AT&T is unique compared to most other versions of the M8 in that you need to be connected to AT&T's network to get the OTA updates.

Running the Euro RUU zip is definitely not the same thing as the AT&T RUU. The RUU checks the CID and MID of the phone. Since the CID and MID on the phone will not match what the RUU is looking for, the RUU will fail.
I haven't seen a Lollipop zip version of the RUU for AT&T.

couldnt connect to wifi

my at&t variant of htc m8 doesnt connect to wifi.
i bought it from a friend.
it searches and scans the wifi networks but doesnt connect to it and it seems the range is low too coz i have another m8 and it catches 3 bars in the room while this one catces only 1.
mobile data wasnt working before as well. i installed new viper rom and the data started working without any effort but wifi is the same. i couldnt connect.
this problem was before i even flashed a custom rom.
All I can think, is RUU back to stock (or update, as the case may be) and see if the issue persists.
okay ill try..
can someone plz guide me? link to a thread? where i can find ruu?
also, i have now bootloader unlocked and custom softwre.. can i still flash ruu?
can someone plz guide me?
i m now on custom rom with s-off and bootloader unlocked
i have a backup of stock at&t stock rom (wifi wasnt working ....nor mobile data) which i had backed up before flashing custom rom (after which mobile data started working but wifi problem still persists)... soo after restoring the stock rom how should i update it? and of course i couldnt update via phone coz wifi wasnt working... so if i find a stock update flashable file on xda should i flash it straight away? what about the radios? and should i relock the bootlaodeR?

That's a lot of questions, most of which aren't relevant to my previous recommendation (RUU - which is not the same as a stock ROM backup).
You can find links (and more info on RUU) to AT&T RUUs on my Index thread: http://forum.xda-developers.com/showthread.php?t=2751432
Latest RUU for AT&T is 4.28.502.2, and you fill find the download and instructions on how to run it near the bottom of the HTC support page linked for RUU 4.28.502.2 on the Index.
You'll need to relock the bootloader in order to RUU with the command: fastboot oem lock
RUU 4.28.502.2 will return you to a full stock image, and the latest official software available for the AT&T M8. Hopefully, this will help your WiFi issue as well.
Make sure you don't have any apps installed that would mess with it. I had one app that no matter how many times I tried to turn off my wifi it kept. It back on
