G Pro 2 bootloops when trying to connect to any data service - LG G Pro 2

Last night, I was trying to play a 1080p, 60 fps video while connected to data (HSPA), and suddenly my phone died (with 80% battery) and entered into a neverending bootloop.
After I came home, I tried Normal Flash via the LG Flash Tool, and I successfully got it to boot into the OS, only to have it bootloop again after unlocking the phone. Next I tried to CSE Flash which removes literally everything, and it bootlooped the first instance, after restarting again, it somehow managed to enter the login screen and I was able to navigate for a little bit.
After that, I deduced that the coast was clear and that it was safe to rebuild my apps and all, but after I tried to reconnect to our WiFi (I had sim and SD card out), it bootlooped again!
Now I'm on my 2nd CSE Flash to have it forget our WiFi network, and try to see if I can still use the phone functionality. If it can connect to a network and let me make calls/texts it's fine. However, has anyone experienced this before? How did you fix it? What was the problem? My initial deduction was that an application or something was causing the bootlooping, but after a fresh CSE Flash, I don't think that's the case. I also doubt it could be a battery problem, since this phone is barely over a year old (around 4 months over a year) and has not suffered any kind of heavy/extreme damage.
Right now I'm trying to revert it back to Lollipop, if that doesn't work, then I'll try KitKat and see what I get.

Literally, just started facing this issue. Did reverting to lollipop work.

[Q] Big Problem With My S3

Hello,
I have a Verizon S3 (SCH-I535) which I've been using for over a year now. I decided to root the phone about a month ago with TowelRoot and everything seemed fine. But just a few days after I had rooted my phone, Verizon issued their KitKat update for my phone (I dont know why I received the update a few months late). I didn't want to update because I knew that if I did, it would just soft-brick my phone. So I thought I would just connect my phone to Odin and load the stock 4.3 firmware back onto my phone (since deleting the root files won't really have any effect). But when I tried connecting my phone to the computer, the computer won't even recognize it (I had the drivers installed). It charges, but it won't get recognized on any computer I plug it into. After this, I realized that the micro USB module got messed up.After my phone wouldn't connect to the computer, I thought that if I had just soft-bricked the phone by trying to install the update and then restarted the phone from recovery, I could just boot up my phone regularly and I wouldn't get the update anymore. I didn't want the update constantly bugging me every single time I used my phone. But to my dismay, the update downloads once every 24 hours. So I used my phone for a few days, but then I realized I that had another problem, none of the Google apps (Play Store, Google+, Hangouts, etc.) were working. So I decided to clear the cache and memory of all of them and sign out and into Google services again. When I tried signing back in, it would say that I couldn't establish a reliable connection to the server, even if I had really fast internet. Along with these problems, I don't receive notifications from any app even if I turn them on and some apps are starting to crash when I open them up, such as the camera app. I've tried a number of solutions, such as trying to install CyanogenMod through Clockwork, but none of that works because of Verizon's locked bootloader. I've even tried factory resetting, and it still soft-bricks that way. Could anyone please help me with this? Thanks.

[Q] No SIM card - Emergency calls only

Hi, everyone, sorry to bother you, but I'm in a bit of a pinch.
My unrooted stock Nexus 5 was running smoothly with then latest OTA update 5.0.1 until I got No SIM card error. I eliminated SIM card as problem source, removed SIM, discharged it completely and after few days turned it on and it was working. But problem returned soon and same method didn't show result. So things I already did:
- check my card in other phone: works
- check other cards in my phone: doesn't work either
- left it off without SIM for a few days
- erase cache
- upgrade to OTA 5.1.0
- factory reset
- unplug battery from motherboard for some time
- flash stock 4.4.4 from developers google com
- put some tape on card to make contact better
in this order. My next move would be to check if SIM card case pins are broken. Warranty expired month ago so there's that. Do you have any advice to give me? Is there any part of the phone that could've stayed not wiped during 4.4.4 stock flash and that's the reason problem remained?
You have a weather widget, clock, GPS location app that is causing the issue. Try uninstalling one at a time until you find the culprit. For me it was transparent weather clock widget that was causing this. Something about the way the app polls the GPS location causes problems.
I flashed stock 4.4.4 and only stock apps are present. I can either uninstall upgrades or root and delete gapps for good. What say you? I think phone somehow got "stupid" hard and I have to reset certain part that wasn't affected during flashing because it haven't once worked throughout process.
My nexus 5 is doing the exact same thing, exactly as you described, since the update. I'm losing my mind
Seeing as we both have the issue I don't think its a problem with your phone in specific. If anyone knows please help! I've tried uninstalling every app, going on safe mode, swapping sims etc

If it happened immediately or just after update try flashing stock KitKat.
Got the same trouble
The problems begun 1 week ago with interruptions with the radio, i have to restart the phone with Stockrom 5.1 self flashed and uber-kernel to get any connection. Switch the airplane mode often to get any radio signals. I ask my provider o2-germany for some trouble in their radio stations - and there was, just a few hours it worked. In a few days ago I traveled across germany, from the south to the north and back, got while traveling no good receptions, only gprs and edge. And now I switched from stock-rom 5.1 to OptiPop 5.1 the trouble begins with no-simcard ...
I will try xTraSmooth 5, when this ist not working i try an older image...
Edit:
OptiPop working now without flashing UBER Kernel. Now Issues so far!
Mine is absolutely stock on 5.1, not seen it once in 18 months and now it has done it twice in 12 hours.
I've always been completely stock and my phone started doing this every time I reboot it. Any more word on this? It also does seem my GPS looses lock on a lot too. This seems to have started since the last OTA update a few weeks back or so.
after i flash latest factory image mmb29v I got No SIM card error. There is an error in Safe Mode and SIM card not detected .pleas help me

Wifi / Bluetooth / Sim Card Issues Since Last Two OTA Updates

I received an OTA Update in early to mid May. I am now forgetting which version I received at that time. ( I forget as I have done so many downgrades/upgrades/factory resets in my troubleshooting the last month!) Up until these issues, I've never rooted or flashed a ROM, or unlocked boot loader or anything. My N5 had always been completely stock.
First Issue
It all started with just the sim card. I get "no sim card" message, even though it was in there. This was my original SIM card and I had never ejected it since I bought it new. I found I could turn it off, pop it out and back in, and boot it again. Sometimes it will see the sim card again. It may take 20 times, but finally work.
I naturally got a new sim card, as well as confirmed said sim cards worked in other phones. My wifi and bluetooth were working fine at first. Working with google support, they recommended a factory reset to fix the sim card issue. Immediately after the factory reset, my bluetooth would no longer turn on nor show a MAC address. At this point, my wifi was fine.
Second Issue
In addition to the sim card slot issue, now my Bluetooth no longer works! Around this time, I received another OTA update, this time it was 5.1.1 LMY48B. I had hoped it would fix the issues, but no dice! I start reading up on the XDA forums as I am determined to start rolling back to see if this will fix anything. I unlocked the boot loaded, rooted, etc following the threads on XDA
Third Issue
I do all sorts of flashing to hammerhead-krt16m_4.4 to hammerhead-ktu84p_4.4.4 to hammerhead-lrx21o_5.0 to hammerhead-lmy48b_5.1.1 . On the final flash back to 5.1.1 my wifi now no longer works!!!!!!!!!!! It is stuck at wifi turning on and no MAC address shows. It also seems my cell data is very very slow now!
After many calls to google, I think I finally succeeded in getting a “ticket routed up”. My phone is from the play store around 10/31/2013. They keep pushing I am out of warranty. I attempt to ask for a refurb N5 without luck so far. I am not very confident anything will come from google. This being my only handset now, it is just not an option to send this to LG. My current state is my voice/txt and cell data are working. Data seems a little slow but usable. Wifi and bluetooth won't turn on. I also still have the sim car slot issue upon rebooting. After a bunch of reboots it will eventually see sim card.
What else can I try? Is there a better way to attempt to repair/reload my radio drivers? Perhaps there is corruption of sorts? I have not tried a custom ROM or radio or kernel…… I did take to a local tech. They looked at everything literally under a microscope and did not see any issues that way. I am in the USA and have a lgd820. Although we are quick to assume a hardware issue, I am wondering if there is some sort of incompatibility with the first run of N5 and lollipop….. who knows!
I’ve read all sorts of threads on the internet. It seems I am not the only one. We are very quick to assume it must be a bad motherboard, it just seems too coincidental to me!

Hi,
This link was actually what i was going to suggest. It seems you've tried pretty much everything in the book except that.
I think its worth a try. Same as any other learning process, take your time and read the whole thing once or twice until you feel comfortable with the process. Then go for it.
Darn it, I should have downloaded those programs BEFORE rooting my phone again. Now I a struggloing to get my SIM card detected again to get data to DL them! whooops!
How would I go about attempting to read my files first to see if they are accessible and potentially write down my old MACs first?
EDIT: I found this but not sure how to get that working? I have Windows 7 and CMD prompt at this point. what program is that using?

OK, I went through those steps. everything appeared to go through correctly. Still no wifi nor bluetooth
EDIT: I rebooted a second time. WHen it first boot up, wifi was on and connected to my works AP. I quickly went in and snagged a screen shot of MAC address. Oddly enough, it did not match what I had input via hex editor. Within a few moments the wifi stopped working. It is back to the turning wifi on issue..... bluetooth still not working as well.
Very interesting.....
EDIT2: I get access denied when attempting to read either files within their corresponding folders under persist.
I was able to copy my stock files into my sdcard download folder and read them there without issue. Thus seeing my default addresses for both!
Perhaps it is normal, but I am never able to edit the old or new files under persist. I basically renamed original folders to bluetoothold and wifiold. I could delete them perhaps.
Note that I put my phone into airplane mode before doing anything noted in the steps.
Any other ideas? Given that it is showing my original MAC address the one time it worked, this makes me think that it is not reading the files .macaddr at all
I have the same problem. Funny thing is, the phone is just over 2 years old and the motherboard was replaced just 9 months ago (so, brand new one).
In my case, I received and Android update 2 days before I found the phone burning hot and restarting on it's own. Then the same chain of events you describe started to unleash. Now I can't be sure if this is software related, hardware related or both.
Can't seem to find a solution to the issue either.

I'm facing the same issues and I tried all the possible steps I could find on internet trying to repair the problem.
Actually, since the latest updates I was encountering some issues with the WiFi only: not turning on either off and not showing properly the MAC addres. So I decided to factory reset, even SDcard and since yesterday I have tried all the possibile guide I found to internet to fix the MAC address not showing and the WiFi not turning on/off but nothing worked. I tried even to flash again the old factory images, such as KitKat, Lollipop, etc., to lock the bootloader again and to dismantle the phone in order to clean the motherboard, but nothing worked. Phone still gives me MAC address 02:00:00:00:00:00 alternatively with the correct one, I can't figure out on what it depends because sometime it seems to work: it shows the correct MAC, it connects to wifi network; suddenly it doesn't!
I'm really going crazy to understand what's wrong.
You'll have to dig up my final posts on this , but in a nutshell, send into LG for repair, select cheapest option they offer. Receive mint phone. My cost was $45 and about one month... I picked up a cheap $20 phone to get me by.
In other news.... I now have a 6p!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[Completed] Sprint note 4 rooted, completely screwed

Got my note back in November, rooted through odin in December. Everythings been grand and perfect.
Till I watched a video on youtube 2-3mnths ago about good rooted apps (wanted to get more daring other than xposed) loaded gsm gestures app? I think was the name. Kept it for a week, didnt use it. Uninstalled it, phone rebooted, instead of the normal "app uninstalled"
After that my phones been laggy, freezes, and freezes and turns off. Its factory wiped itself 8 times. I have countless posts on Reddit timelining everything. Long short is, tried liquid smooth to see if that would fix my problem, lost text messaging with that could only text for an hr a day, flashed stock sprint firmware and rerooted afterwards, have been slow to reload apps on phone, incase of factory reset or whatever. my phone is now taking 75+ batter pulls to get into a normal boot, every 15bat pulls it jumps into download mode "could not do normal boot ddi_mms read fail" and now an ssl text ive only seen once today, ill try and write that down if it happens again.
Finally when I get back into my phone, sometimes I have to update prl to get service again, the other day my phone lost signal and all my network settings were unselected, I had to select them all and my phone was fine, then I was on the phone and it cut me out in the middle of a call and said roaming lost or something, and I had to reapply cdma/lte on sprint.
Im beyond frustrated, im getting married in 2 weeks, and going out of country immediately after, so I need a working phone as most my business is conducted through it. I have no upgrade on sprint, and cant afford to throw out 400$ for a "new" note 4
Please please please someone help me.
Thanks for your time.
Matt
Hi,
Here's a thread on returning to stock firmware. That should give you a fresh start,

If you want to find other options, you could ask for other ideas in your device section here,

Good luck!

Softbricked, basic usage no rooting.

Gday everyone.
I just got this phone and since it was first powered on I've had issues. I will likely be going back to the carrier tomorrow and asking for a replacement, but wanted to put my experience down here. Ive looked at a lot of other threads, but all of them involve unlocking of bootloader, flashing etc - I havent done ANY of this (yet). Its fresh out of the box.
Location: Australia
Carrier: Optus
Model: MHA-L09 (cant access extended model number)
So first up, had issues connecting to the carriers in-store wifi, which uses a captive portal.
When I finally got it going I was presented with a Chinese site - id accept this usually considering it is Huawei.
This phone is a replacement for my dead Note4 and as such I wanted to restore apps, as I had no internet, I skipped the process.
Got back to my office and connected to my wifi fine, so decided to factory reset to get a fresh start.
Noticed that after reset the initial process was in a different order. Restored from Google and all apps downloaded, happy days for a couple of hours, just waiting for my service to port over.
2 hours later, I decide to restart the phone, it gets hung up on the Optus logo which is displayed before the reboot starts.
Hard reboot.
System loads, I figure I may as well see about a firmware update. Get 'Package installer isn't responding' errors. Try again, works, no updates available.
Go to google photos, get 'Package installer isn't responding' error.
At this point I think, f**k - what is going on here.
So I reboot into recovery to wipe the cache. This processes fine, but then the option to reboot the phone doesn't work.
Hard reboot.
Boots into recovery without me touching it.
Hard reboot. - happens again.
So then I think, fine ok, I've upset the balance, lets do a factory reset.
Factory reset hangs on 99% for over 30 minutes.
Against better judgement - hard reboot.
Now I have the EMUI logo with a nice round 0% under it... and that's where its staying.
Thoughts?
I have to fly interstate on the weekend and cant really afford unreliable comms. Should I ditch the Huawei?
Thanks all.
So - it seems that nowhere did i find a mention of the fact that if i plug it into my PC and goto the recovery mode, it loads eRecovery. Whilst this didnt actually work (I believe it only works for CN firmware) It did give me a shutdown option. I shut it down and started it again and im back into a fresh install.
Lets see how I go now...
Never restore backups from other phone.
Wow, helpful.
I didn't restore the backup from another phone, just apps, ie google downloaded the apps I selected.
The device is still performing poorly, even a standard reboot does not succeed, instead it hangs on the carrier logo before actually rebooting.
Ill take it back to the store tomorrow and ask for another one, im hoping Ive just gotten a dud.
