[Q&A] US Dev/AT&T 442/443/444 Debloated VVM/ISIS Release 10-19-2014

um those aren't the flashing instructions....not sure where you see that for Lollipop.


***Current 5.0.1 Lollipop Flashing Instructions***

If you have not flashed the 5.0.1 firmware it is included:

CID's that will flash correctly
cidnum: BS_US001
cidnum: BS_US002
cidnum: CWS__001

****S-OFF is necessary to proceed with flashing firmware package****

Extract firmware.zip from zip, copy to adb/fastboot location,reboot phone into bootloader connecting it via fastboot option,run commands listed below

Also included in this firmware package is the modified hboot with red text removed
IF you do flash this firmware package the commands to do so are as such:
* 1.fastboot oem rebootRUU
* 2.fastboot flash zip firmware.zip(if needed re-run this command)
* 3.fastboot reboot-bootloader

After flashing this firmware package stock recovery will be installed,extract twrp_2_8_3_0_m8.img from zip, copy to adb/fastboot location reflash twrp recovery that is included by running command:
fastboot flash recovery twrp_2_8_3_0_m8.img

Now after flashing twrp reboot device into recovery,do these steps as it is important!!
factory wipe device,click advanced wipe and select data,system,cache and dalvik wipe these partitions.(TWRP will reload,do not flash until after rebooting recovery) Once this is finished reboot recovery and proceed to flash this ROM

On the flash guide for the Lollipop release, I'm confused. Is this the correct procedure?:
-Put full downloaded zip on root sd of phone
-Put full downloaded zip on computer and extract contents
-Follow fastboot instructions with firmware and twrp files in the adb/fastboot folder
-Reboot to recovery, wipe, etc.
-Flash full unextracted zip download from sd card

The reason I ask is because it seems like the zip file placed on the sd would be wiped when following the flashing directions, also the stock recovery and boot.img and some other files are in that zip, will they affect the flashing of the rom? Or am I just missing something?

I was summarizing. I found the answer in your development thread, was just confused about whether zip would be wiped and whether extra files in zip would affect flash, they don't, install went fine.

Lollipop w/o firmware

Hello, so I'm just wondering if WNC has posted his ROM for the latest AT&T Lollipop release that doesn't include the firmware? I'm S-on and just looking for the ROM, don't see it anywhere and wondering if I missed it.

Thanks.

 

[jon145]

Just extract the Rom zip from his package. I'm running it right now.

Got an issue right now. Followed install guide but my phone will not dial out. Immediately disconnects call. Doesn't even ring.

data and WiFi works absolutely fine though. Any ideas?

Got an issue right now where calls immediately drop when being made. Data and WiFi works fine just can't make any calls. Any ideas?

I had this same exact issue (I flashed the ROM yesterday and just noticed today that phone calls weren't working). The fix for me ended up being disabling the enhanced 4G LTE here: Settings > Mobile Networks > Mobile Data > Enhanced 4G LTE Services

Was that the same you did or did you find another fix?

 

[Wonders_Never_Cease]

Calls not coming in is firmware issue....have to flash full att firmware,or run ruu back to att files...full wipe is required also.

The weird thing is the calls don't work at all (Inbound/Outbound) with the Enhanced 4G LTE Services enabled. Once I disable that feature the calls work fine. Is that normal or should I still flash the ATT firmware again?

The first time I flashed rom I did not wipe after flashing. I did wipe BEFORE flashing.
The instructions IIRC say to wipe, flash, then wipe once more. Once doing that second wipe, I had no more issues with calling/receiving. But I am running Viper now lol.

Back on this ROM and I have the same calling issue. With Enhanced 4G LTE services disabled calls work. Not sure why my buddies with stock phones do not have this issue and can utilize VoLTE. This ROM is supposed to be the closest to 100% stock right?

Did you ever use the at&t RUU? You need to fully flash the firmware. And also make sure you have a newer sim card. I tested this before he even released it and it works fine it has to be something on your end

 

[Wonders_Never_Cease]

As you are having this issue across multiple roms you have tried, there is something amiss on your end. viper is euro based and you had same issue. Ill bet your running an older sim that is not provisioned for VoLTE. Or you have flashed a euro firmware which does not play well with the new att features they have implemented.

I flashed the firmware included in your package. I believe 4.28.502.1, is US firmware no? I just want to avoid doing RUU as I really do not want to wipe my entire phone.
I've got way too much camera photos to back up lol

And I actually went to ATT yesterday and got a brand new SIM thinking I had older sim, not the problem here.

Then that is the problem, your going to have to flash the ruu, only way to fix it you need a full firmware update so you get rid of whatever euro stuff is messing with it

Yes. But you'll need to have s-off, and change your CID and MID.
