[Q] [HELP] My LG P970 is stucked on LG Screen

Hello guys, I am new at this forum but I have been reading this for years, but just now I needed to post something.
I have a LG Optimus Black P970 and it's now Bricked, I will try to explain it.
The samrphone was from my father and he gave it to me already bricked, he was using Stock ROM from VIVO (Brazil) Android 2.2 (Froyo) when It bricked, then I asked for him the smartphone and I tryed to use the SmartFlash to unbrick it and put the CWM Recovery as I used to use. The P970 didn't boot at CWM Recovery automatically as was supposed to, but after few hours pressing Vol - + Home Key and Power Button I was successed. Then I flashed Zeus ROM and everything went fine, the P970 was UNBRICKED!. Ok, I gave it to my sister-in-law and she was using it untill tomorrow... Then she asked me to unclock the network so she could use every SIM Card, for this I had to flash another ROM, I asked the P970 to boot into CWM Recovery (holding power button, reboot>reboot recovery) and now It is stucked on LG logo again. I tryed to flash 5 Stock Firmwares, 10A, 20B, 30A, 30B, etc but none worked. I really need it unbricked. I have been searching tought internet but every tutorial didn't work.
Please some one help me, I can't lose this smartphone. Oh, one more thing, I can boot into S/W Upgrade normally...
Thanks!

So you have tried using the smartflasher?? If so then it should be fully fixed... give it sometime to boot though as when I'd restored mine it took like 5 mins top for it to get into the main menu..

Yes, I did it several times and didn't fix the bootloop.
Is there a way that I can wipe data/factory reset thought a computer? Because maybe It could fix my phone, but I cant boot, it's still stucked. I really need help here

any help?

Hi MuriLOCO, I had bricked my p970 before and flashing via flash tool did the job.
You can try flashing it via S/W upgrade.
Go to LG website and download the updater so you could flash it with S/W update.
Hope that helps.

[HELP] XT1058 Suddenly doesnt boot

Hi guys, i have a weird problem here.
I have updated my phone to 5.1 a couple of weeks ago and on friday 08/08 i let the phone discharge completely , put on charger and went to sleep.
When i woke up, tried to power up the god **** phone and it just froze at Motorola Screen, then boot it up to fastboot and tried to Factory Reset him.
Dont know why, it didnt worked, then i unlocked the boot loader and tried to flash via RSD with a Stock firmware of the same version xt1058_ghost_retbr_5.1_lpa23.12-15_cid12_cfc
After flashing everythink looked normal, but the problem persists, Manually flashed GPT.BIN, still doesnt work.
It start, goes to the animated moto logo and later the screen goes off and nothing happens. PLEASE GUYS HELP ME HERE!
(Sorry for the worst english that you ever seen here in xdaforum)

Why update phone stuck at bootloop? 20i to 20o.

My phones stucks at bootloop after ota update, so I decided to flash kdz via LGUP. (v. 1.14.0.3). Then I tried it two times and I have no errors both of pc and phone, but phone stuck at lg logo(one time T-Mobile logo appears and suddenly rebooted itself). Also, the second time I get some unexpected things like the phone says it is h81120o but LGUP recognize it as h81120i.
Anyone has this problem? Can I flash again h81120i?
Edit:Thanks for everyone who helped me but I am so bored to deal with it. So I give up to try and I will use my old phone. (All photos are removed by me)

i think its normal.. it says 20i cause it was on 20i.. once you flash it. hte next time it would say 20o..
as for the reboots i think you have the infamous bootloop.. so it must be sent to LG for repair.. sorry.
noooooooooooo dont flash 20i
20i its antirollback V2
20o its V3 if you do itll brick phone.. so you stuck on 20o...

I'm not in U.S. It was bought by my friend when he was in U.S. So, No option to send it to LG. I talk with lg service center, they says I have warranty but they need a physical address.
My phone optimizing 55 apps when first boot then finishing boot and then it reboots and stucks at T-Mobile screen. Just for once it ask for first setup configuration but it shutdown because of my battery is too low. After that it doesn't boot any more. Do you have any suggestions to back it live? I have download mode and factory reset and pc can recognize the phone. But this is first time I deal with this issue.
<deleted>-Please look for photos what I have first time it boot normally after factory data reset.</deleted>

best thing is to have it repair... but if you cant.. then no.. theres a TOT file that disbles big cores .. but only for h815..

Stuck on LG Bootscreen only download mode, LGUP didn't work

Hey Xda-ers,
I'm freakin out about my phone. I was using hangouts this morning and it just rebooted itself and got stuck on boot screen. It has NEVER done this before and always worked fine. I was on USS Enterprise ROM I believe. I can only get into download mode, so naturally I tried to flash stock h81120o (the version I was already on and rooted) and LGUP completed fine. Only my bootloader was still unlocked and it still was stuck on boot screen. Does anybody know what I can do to at least relock the bootloader so I can do a warranty claim with T-mobile....or get my phone back working if this is not catastrophic.
Oh I also tried holding down & power, no recovery...and cannot use the buttons to factory reset either. Then it loops and get stuck again.

Ditto

How can i tell if this is indeed a hardware issue ? I am guessing it is though also the serial number falls in the problem range.

in safemode can you see big cores working.? are you bootloader unlocked?
thats supposed to be fixed but still some had hardware failure.
some disable big core and leave all small 4 cores and they work..
or get a new motherboard.. unless you have a way to ship it to someone in usa and send it to LG usa.
