Details...
What ROM?
What Kernel?
What Modem??

There is not enough information. Exactly what rom were you flashing? Big chance the it's the kernel. It was probably flashed improperly or an incorrect kernel.

[Q] Bricked... and bad battery :(

Just to explan in short notes how everything started..
I was using "ICS GPCR V2.1 by P-VLAD" happily for about a year i think, didn't have any problems. Then one day when i started to play some game my phone just turned off. After that i noticed that my battery drops to zero when i turn my phone on again. I noticed after, that my phone shuts down always when i watch 3d stuff or when my flashlight is on, after 1 or 2 minutes..
So i thinked it's time to refresh system.. So i went to factory reset on phone settings (not on recovery). Then i fell in bootloop. I don't know why but then i started TWRP and wiped cache, dalvik, system.. And that's it, im now in bootloop.
After that i accidently saw that i have inflated battery, so system probably was not the problem..
I readed everything from around this and...
Flashed again TWRP, bootloaders with "SimpleTool" and "OS Hacking" (tried them both), then i tried again to flash P-VLAD ROM but nothing, just says "booti: mmc_read 0x55e2dc" and bootloop stays. Tried "Universal_RecoveryLoop_Breaker.zip", then flashd everything, but it's same again.
I don't know it's possible because of bad battery that those tools cannot do their job. Also when i flash ROM i must get phone to charger..
What to try next?

5.0.1 manual flash - getting stuck on software update screen

Hi all,
I downloaded 5.0.1 factory image and flashed all the files (except for user data and cache) through fastboot and everything went smoothly....once the phone reboots, it asks for language etc - then connects to my wifi and gets stuck on "Software update" screen - it shows "checking for updates" and nothing happens. I tried rebooting and turning off the wifi connectivity and it still does the same thing over cell network. There's a skip at the bottom but it's deactivated so I can't click on the skip. Not sure why it got stuck on this screen....anyone seen this happen?
Any help would be greatly appreciated
thanks

I left it overnight but, still its stuck ont he same screen. I made sure I did flash Hammerhead
I made lrx22c - so it's not the issue of flashing wrong files
any help please?
Interesting thing is I tried to flash back to 5.0 and I still get the same error message.
I know it still has all my data as it automatically connects to my wifi.
Not sure what am I doing wrong?

Were you on 4.4.4 before? If so you're going to have to flash userdata.

Need Help : Phone restarts itself !

I have SM-920V , verizon branded galaxy s6 . my problem is , when i turn on phone , it restarts itself...
I've tried everything , reseting/erasing , flashing firmware with odin , flashing and updating firmware with KIES . It still same , restarts before or on activation screen and can't past it .
It's turned on only for minute or less and then restarts , bu when it's in download mode i can flash firmware without any restarts or so... (more then hour)
So any suggestions?

try this, turn off wifi as soon as your phone boots up.

i can't , because settings menu is not acceptable on activation screen
Also it's not connected to my wifi network (i've mac filtered network)

I had similar issue with wifi being the culprit.
As soon as it boots up, wipe down notification tray and disable wifi toggle. See if that works.

If nothing works, take it back where you bought it for replacement.

No service issue

All of a sudden my OPO started to show No service. But it detects the sim and imei shows a valid value. Wifi works properly but the neither calls nor data. Once rebooted the device shows Airplane mode when power button is long pressed but it is not shown in the home screen. It was running the latest OTA. I tried
* deleting APN and loading the defaults
* trying to turn on the radio via *#*#4636#*#*
* flashing the latest OTA via recovery
* flashing the latest factory image via fastboot
* flashing an old factory image via fastboot
* flashing an old modem via fastboot
none of those methods worked.
Please help me to bring my OPO to normal condition. Thank you.

Hey have you found a solution? My opo started yesterday afternoon running into a lot of issues with service connection and then just no service all the time. I tried most of the things you did and no luck went to tmobile and they didn't help much but gave me new sim which seemed to help some. I have some connection outside but soon as I walk indoors the internet drops to g or edge barely ever lte. And my connection is spotty. Its only been few hours with new sim so I'll see tomorrow if same issue persists.

I have the exact same issue as you and I haven't yet been able to find a fix.
I've tried absolutely everything including:
- Changing the modem
- Wiping the phone completely and reinstalling my Rom
- Trying every other Rom out for the OnePlus One.
- Reverting back to the Stock CM11 Rom that came with the phone.
Nothing helped my issue. My phone would just go from 4g in some places to 2g in others, And sometimes I wouldn't even be able to get a signal, it would just say "No Signal" or "No Data Sim"

I had similar problem few weeks ago, but also my sim card was not detected... My solution was to flash twrp 2.8.0.6 and flash OxygenOS TWRP compatible . This one https://www.androidfilehost.com/?fid=24385658843824180 and after that everything has started working, IMEI , APN settings , sim card, and data worked... and after that you can flash whatever you will. And remember , always make a nandroid backup . Backups are real life savers out there. Let me know if that helped in your case.

I've just tried it. No success, same issue persisted. Not a big fan of oxygenOS anyway.
