Android is upgrading and then bootloop... - G2 Q&A, Help & Troubleshooting

I recently upgraded my ROM to the latest version. Wiped the cache and davlik, flashed the new rom and then flashed GAPPS. The rom boots and shows Android is Upgrading but after a few seconds, it reboots again and goes through Android is Upgrading again and restarts prematurely.
Also tried only flashing the rom without gapps but I am getting the same issue.

Did you wipe data or was it a dirty flash.

It was a dirty flash. Then since it failed, cleared data and system and flashed but still no dice. Flashed the latest Cm nightly and it worked. Been using it since. Might be a problem with the rom. One other person had a similar problem though there are some people who used the same zip but didn't face any troubles. Looks like Cm for now

Yea I know it sounds weird but not all phones are created equally. I had 2 galaxy s3's, one Rom would work on one and not the other. It's definitely strange.

Apparently, it's a recovery issue. I'm on CWM. People who have flashed it successfully are on TWRP. Will give it a shot over the weekend.

The problem was indeed CWM. Flashed fine with TWRP.

Root access with PA 4.3

Does it work for anyone? Upon first boot it works like normal but after I reboot it thinks I don't have root anymore.
Try rebooting again, some got this issue.

Did you reflash su after flashing the rom?
I put it in my flash Q with the rom and gapps.

The newest PA apparently you don't need to flash another zip so I deleted it after it worked on first boot.

[Q] i9505 wifi hardware fault?

Wifi turns off by itself about 3 minutes after connecting to a network. At times it even reboots itself trying to turn wifi off. Sometimes it even cant detect a wifi signal even though its within strong signal range.
Tried full wipe and reflash stock firmware but to no avail.
Do you guys reckon its a hardware fault?

It could be, but what firmware/kernel version are you using? Wifi is a kernel issue, not a ROM issue per se, but if you are using a custom ROM and custom recovery, you could have flashed it with the wrong recovery and ended up with this sort of mess.
Most common scenario?
Flashing custom ROM with TWRP or the wrong version of PhilZ recovery or even an older version of CWM.
Any of these can screw up your device.

Previously on ARHD 3.0 flashed with Philz as instructed. Been using it for almost 2 months without a glitch. All of a sudden this happened.
Ive now reverted to stock as u see in screen cap. But still doesn't solve the problem.

Do you guys factory reset after flashing CM?
The best way to install is to flash Official CWM recovery from their website (Google Clockworkmod), download .img file and flash with SGS4 FLASHER from Play Store.
Boot to recovery
Go to mounts and storage
format system, data, cache. (make sure you've done a backup of current ROM before doing ths)
Then flash CyanogenMod ROM
Then factory reset
Then reboot
You should be fine
If you get stuck on splash screen it's cool, Just hold power down and try again. You may need to keep doing this till you see CyanogenMod boot animation. I've had to do it 4 times before it would finally boot. It's normal though just something weird with CM10.2 kernel. If you flash a custom kernel it boots fine everytime

Yeah i always factory reset before a fresh install of a rom. So the file is actually 200mb then? Seems a bit strange to me.

[Q] Very Strange Problem

Hey all, I'm having a problem with my nexus here and its driving me crazy. Basically i was behind on updates and running 4.2.2 (Paranoid Android) until today. I decided I would upgrade to the newest Paranoid android 3.99 RC2. First off, i downloaded the stock nexus 4 images, and flashed em all through fastboot. Then i flashed the newest CWM (6.0.3.8 i think) and proceeded to flash PA.
But when i booted into PA, i had no cell connectivity as well as unknown baseband, imei, and imei sv, even though the baseband is clearly shown in fastboot (its 0.84). I tried reflashing the baseband, no luck. So i reflashed the stock google img's and my imei and everything came back.
So i tried a second time and it still didn't work. Seems like whenever i flash PA, i lose my imei and baseband.
Help me out guys
Anybody?

DID you do a full wipe before flashing?
I would be very careful and stay stock until you get an answer. Without IMEI your phone is illegal and won't work. I've stayed away from C /M as it's buggy and has too much trouble, like this.
Sorry

Try using latest TWRP
I got this last time I flashed paranoid android. I had to use the LG tool and download mode

If you are coming from 4.2 make sure to flash 4.3 Radio and Bootloader!!
Follow this guide:
http://forum.xda-developers.com/showthread.php?t=2389721
Yes, I did a full wipe, even the SD.
I flashed the full 4.3 stock Google image through fast boot first. So I should be totally up to date.
I will try TWRP and see if its the new CWM that's messing things up.

The CWM version you used has a bug which derps your baseband when you flash anything. Simple fix: install any other version of CWM or use TWRP, then flash everything again (radio, rom, whatever). This happened to a lot of people. You'll be fine.

KitKat Roms Failed! ~G2

Using twrp ...Whatever the most recent is 2.6.3?
I,have successfully installed cm10.2 Roms in the past.. However when I do the same with a kitkat ROM.. It always fails, I've tried paranoid and cm..... I've wiped, cleared cache and dalvik but alas to no avail :3
Does anybody have suggestions? I almost died of smiles when knock on worked in 4.3 cm (kind of) but I'm sick of the stock ROM and lg's...... Sh-ware
Sent from my LG-D802 using Tapatalk
There's a discontinued 2.6.3.4 in the Original Development section. Flashes kk ROMs just fine

Seems flashing that particular recovery with flashify is... Unhelpful xD just fails to boot into even lg's three power button precursor
Sent from my LG-D802 using Tapatalk
Yeah, I encountered problems through flashify too. I just flashed the zip from TWRP 2.6.3.x, then rebooted the recovery.
Sent from my G2 using Tapatalk
Hey for 4.4 Roms you need twrp 2.6.3.3...comes in a zip so easy enough to just flash!....also Philz custom cwm recovery supports 4.4
yeah update recovery,but also do a system and data wipe as well.
be sure to have a backup
and fully downloaded rom.
