HELP! G2X will not boot up, will not factory reset

I just got a replacement G2x and ended up one click rooting it. I installed bloat freezer and started freezing programs that I did before. I accidentally froze "launcher" since I am using launcherpro anyways. It seemed to be ok, but then I froze App Pack and it gave me the constant force close like some of the apps do. I pulled the battery and upon starting it up again, it gives me the LG logo at full brightness. It then dims to half brightness and then goes black. (unresponsive)
I try power + volume down and it brings me to the unpacking android like it should for a factory reset. Shortly after, the screen goes black and just sits there unresponsive but with the notification lights lit up. I had not gotten around to doing an nvflash recovery yet and dont have rom manager or clockwork installed yet. I just want to get back to stock or be able to at least boot up.
Please help.

I believe factory reset on stock recovery is volume up + power. Either way, I'm pretty sure you have to hold them until it starts the restore process.

Nvflash CWM recovery, restore the stock nandroid dump.
This should take roughly 10 mins to complete and will get you back to stock (minus the recovery).

what he said. took the words outta my mouth ahah

Thanks guys, I had done the NVFlash before, I was just worried about bricking my phone if I did it when I wasn't supposed to

Well after doing all that, it still only boots to the LG Logo. I can enter clockwork recovery and even do a factory reset (and the G2X stock nandroid backup) but when I restart the phone it won't bring me past the LG screen.......
Any other suggestions?

Send it back saying they sent you another messed up one, and then again I suggest to you and everyone else to forget about rooting, since there are more negatives that outweigh the benefits to a rooted phone. It's just foolish and it's no wonder that the G2x has a lot of problems, it's because most that do complain of a problem have rooted or tried rooting the phone.

If I send it back and they get it to boot, it will still have superuser which means it was rooted. I don't want them to void any warranty and I am sure they would not have let it out of the warehouse like that.....
Rooting is not the reason the G2X has problems. LG is the problem....
Anyone have anything useful for me to do. I like that I can at least enter recovery and do a factory reset, I just need to get this thing to boot past the LG logo.

Did you do full wipe before restoring. Install a different rom instead of stock....

After you did the reset and it would not boot up - have you tried pulling the battery and booting up again? I have had to do that a number of times.

I have pulled the battery so many times. What will flashing a new rom do that a stock rom won't?

After you restored the stock nandroid, did you wipe data, cache, dalvik again?
Wipe before and after restore. It works, I've done it oodles of times.

In addition to what GideonX posted, make sure you format system, format cache, and format data.

I did just as Gideon stated and it still cannot boot past the LG logo. I wiped everything before, flashed Gunmann's stock nandroid backup, then wiped everything again....
What now?

This same thing happened to me on my second night of fooling around with the phone. I fixed it by reflashing with the nvflasher. Make sure you follow all the steps to the T.

I followed every single step exactly. I ended up just putting the battery in and it booted fully after about 5 hours of sitting there. The battery was at 1% about to die. I don't know what made it boot up near its battery death. Either way, I was able to unroot and the next time I turned the phone off, it wouldn't boot again. It looks like it is an issue with the phone itself

Same problem
Hey, did you fixed the problem??
I'ts happening with my G2x...
Some times, it wont boot up, i leave it alone, and then powers up with 1% or 0% battery.
Today booted up with the right charge. And works flawlessly. But if i power it off i'm shure that the problem will be back.

How do you do that? Pleas tell

Go to the ROM for recovery thread in development section and follow it step by step.

[Q] Bricked for no apparent reason

I rooted my phone back in December and have been using it without problems since then. I've rebooted it tons of time, haven't installed anything unusual or tried to modify anything. I just followed the normal instructions for rooting and flashing a custom rom. Today, I rebooted my phone and now it's hanging at the Galaxy SIII logo screen. Taking out the battery didn't help. I have no idea why it would do this out of the blue. What are my options for fixing this? Can I recover my data?

Should be easy to fix. Common issue.
Try booting into recovery. If you can then clear cache and dalvik. Try rebooting then.
If that doesn't work try re flashing the rom,
If you can't reboot into recovery but can get into download mode then you can easily fix it at the cost of losing all your data.
Let me know how it turns out.
At this point, my phone is just one big tweak.

Wiping the caches didn't work, so I ended up having to reflash the rom. Everything seems to be back to normal now though, thanks!

[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?

[Q] Restart loop(not bootloop) - really weird

Hey lads,
I got a really weird problem and I've tried nearly everything I can think of. I had EMUI 2.3(b121sp06) and I tried the online OTA update to b307 if I remember right(was automatically suggesting the update) and at the update screen it loaded to about 99% and then stopped. Said not to press power while on this screen but obviously it wasn't going to finish. So I reset the phone and it started the "recovery loop", so basically keep trying to apply the update. I had to flash CWM to break out and flashed the whole system by hand(recovery,system,boot,cache,cust and userdata img files) and it starts up but it keeps resetting and seemingly it's random. Android boots up, I don't touch the phone--> boom reset. Weird thing is it even does it in recovery.
If I really want to explain the problem it's like as if my finger got stuck on the power button(that naturally made me think that the button might be f*cked), but booting into fastboot and not having resets cleared my suspicion. What I also noticed is that every time it boots up it doesn't recognize the sim card and I have no signal or whatsoever.
Tried multi tool unbricking method -> doesn't work
Tried factory reset from stock recovery(had to be fast so it doesn't reset before) ->doesn't work
Tried wiping dalvik cache and factory reset from CWM ->doesn't work
Tried killing battery by letting it keep resetting -> battery drained, reset loop stopped ->put the phone on charger->reset loop started again
I have no f*cking clue how can I get out of this, will keep trying though. Any help is appreciated, thank you!

Hi
Did you try to remove the Sd Card ? Honor 6 reboot is often due to faulty SD Card.
Which model do you have ? L04 ?
B307 upgrade sure ?
Seb

Yes, that was my first idea, still does it though. I have the L02 and I'm not positive it was b307, but it started with 3, could be b303 if there is one.

I don't know for L02 but for L04 there is a Full ROM that you can flash with the three buttons method. (Vol+,Vol-, power and put the ROM in /dload folder on the SD card).
Maybe there is such thing for L02 ?

There is, but as I said the phone restarts even in recovery. It's like the phone restarts every 30 secs except for fastboot.

if it's not SD card or internal flash problem so, it seems to be hardware related to me (

Would make sense but it occurred only after I tried OTA. Would be really surprised if that killed that hardware :-/

Its might be a battery problem Or power flex cable. Try to turn on the phone during charge

guys im facing the same problem now... waiting for any solutions

I have tried stop & uninstall some app
I've tried as quickly as I can when the phone (nokia x) is on, then I stop> uninstall I consider potentially cause this problem (facebook, whatsapp, uc browser) and then it managed to prevent the continuous restarts. but problems arise even though the application had me uninstall and then I restart the phone. and it is back again, I uninstalled the app that has remained with the error settings and restart repeatedly. who knows what else : '(

Sent from my Honor 8 using XDA Labs

In the past my battery lost it's endurance pretty much. Furthermore I've read that a defective battery causes lots of weird behaviours on our Honor 6, which was the same to mine.
In my case a replacement of the battery worked well, to get my Honor 6 back to life:

It's not that difficult and lasts approx. 30-45 mins. Spare Batteries are available for 6 - 10 bucks on ebay or directly from the chinese internet stores.

Samsung Galaxy S6 randomly restarting / gets stucked

Hello guys!
I am encountering an issue with my Samsung Galaxy S6 G920I. The phone suddenly started to restart on its own every 30 seconds or so. After some restarts the phone started to get completely stuck in a randomly time matter, and the only way to take it out of there is by doing a hard reset (volume down + power buttons).
I tried everything. Did wipe cache and factory reset in recovery mode, flashed a new stock ROM with Odin several times but it is still doing that.
The stuck issue also happens on screens like "installing update" or "erasing", after doing the ROM flash with Odin.
Any thoughts?

Try device initialization using SamsungSmart Switch. it Should solve the problem. But that method wipes entire internal storage. So backup before you do anything,
Device initialization is something like resetting it to factory setting by clean install of the firmware.

Hi, could you fix it ? The exact same thing happened to me. I was using stock firmware (I never rooted it or anything) and it suddenly began to reboot by itself. It can be stuck in a bootloop for 2 straight days and then suddenly boot normally and use it for a couple hours until it starts bootlooping again. After a month of having this issues I decided to flash stock 7.0 firmware with ODIN and also with Smart Switch but after succesfully applying the update the phone reboots with the "installing system update" screen and then it gets to 32% and it says "erasing" after which it starts the bootloop once again. I'm stuck with a $500 paperweight. I'm afraid it could be something with the motherboard any help is greatly appreciated!
