Fixing Blank Screen

Hey All,,

Stumbled on this thread today after a month long battle with what I thought was an H-815 but in the end turned out to be an F-500 in diguise ;)

Long story maybe some other day, but for now, those of you with Blank Screen after you flash h-815 kdz and the phone boots up - If you experience any or all of the following symptoms:

The led flashes; phone makes booting tone; red charging led when plugged in; pressing Vol- and power key (screenshot) gives shutter sound; and finally, in totall darkness, there's a faint backlight ;

I offer the following 2 fixes (that I stumbled upon purely by chance! well- mostly. Okay. For the 1st tip, I got it off XDA so even though 'twas for a different issue, credit where its due, I suppose :cool:):

1- Freeze it. Yes. Stick it in a ziplock and leave it in the freezer for 15-20 mins. Then boot up. After a missed heartbeat or 2, you should see the LG logo and phone will boot up and the screen will stay on. And remain that way, until you need to reboot. Then you gotta stick it in the freezer again. For another 5-10 mins.

How? Why? What? Where? I dunno. If it works for you, then offer thanks to whatever Gods may be and dont question their will. And be near a freezerwhen you need to reboot.

2. To get into Download mode, another trick that worked for me is to:

i- Take out the battery.

ii- Plug in the USB cable.

iii- wait till the screen lights up and a battery icon with a question mark appears.

iv- Press Vol +

v- Stick in the battery.

And if you did it right, Phone should enter download mode.

It takes a few tries. Note that if you stick in the battery (without pressing Vol+), the battery indicator will change to show you how much percentage remaining and your screen will turn off again.

Also note that If you stick in the battery, and immediately take out the USB cable, the screen will turn on but phone will enter bootloop. Atleast it did for me. Might not for you. Give it a try, why not! :)

I hope this helps out a few of you at least. I got so many good tips here on XDA that i figured its time to register and give back.

Need help. pls.

I Bought a lg f500l online . prerooted and flashed with h815v10h. I upgraded to marshmallow h815v20L without knowing its f500l . Now the signal reception is very low. I'm not getting reception inside my home. I used to have 3 bars inside my home. Now no reception at home and 2 bars when i go outside. Will this method work? If yes, Should i use all the above img files? Because only the problem is with reception. Or will flashing lg f500lv20u solve the issue. Pls help

[Ascend Mate 7 Q&A, Help & Troubleshooting] vonotny:
This is a somewhat silly question, I admit. It's reasonable to assume that Huawei will provide Android 6.0 to their older phones, considering they just made the new Nexus 6P.

Or will they? What do you think? Is the Nexus 6P comparable in terms of hardware to our Mate 7? How are chances that we'll actually get Marshmallow within a reasonable time frame?

Also, what do you think - will Marshmallow make it possible that we could get a CyanogenMod installation for the Mate 7 with support for the fingerprint sensor? Or another, similar, close-to-stock Android experience?

I, for one, would rather wait for Marshmallow and stick with KitKat for the time being, hoping that the new system will improve significantly on Lollipop - and also hoping that the Nexus 6P means adoption of Marshmallow to the Mate 7 and other Huawei phones will be much quicker (and easier).

What are your thoughts?
[Ascend Mate 7 Q&A, Help & Troubleshooting] ГАСООП:
we are waiging a year for lollipop. i guess they'll release finally this goddamn lollipop just to get rid of haters on their fanpages and forget about mate 7.

if you are expecting 6.0 in reasonable time you are just dreamer.
[Ascend Mate 7 Q&A, Help & Troubleshooting] gee2012:
The Nexus 6P will be updated by Google and not by Huawei to be clear and i`am afraid we`ll have to wait for the M update at least 6-9 months if they continue developing Lollipop. The Nexus has a different CPU and GPU then the Huawei`s/Honors so that won`t help either. I`ll be switching to the Moto X Style soon i`ll think because the Nexus`s are ridiculously expensive this year imo, at least in the EU :silly:
[Ascend Mate 7 Q&A, Help & Troubleshooting] dpanter:
No, it isn't.

If Mate7 gets M, great! Just don't hold your breath... :fingers-crossed:

[Ascend Mate 7 Q&A, Help & Troubleshooting] gee2012:
Hope this is legit but i have serious doubts ;)
[Ascend Mate 7 Q&A, Help & Troubleshooting] AhsanU:
The AM7 hasn't even received an official Lollipop update, the mere thought of getting Marshmallow is a dream. Huawei has been promising it every month, and has failed every month. I absolutely love my AM7 physically, but the software is outdated. The fact that Google will be in charge of the 6P's software is the only reason I bought one. Huawei has physically built some amazing phones, but hardware needs to be complemented with software, and the fact that their 2014 flagship device has not received the 2014 update to 5.0 a year after its release leaves me saddened for Huawei customers that can't change phones, or are committed to their AM7's.

Different strokes for different folks I guess. Many owners are content with 4.4.2 or the various CM based ROM's out there, but I believe it's reasonable to expect a vital software upgrade to a flagship device within 5-6 months of its release. We're nearing a year and still are going nuts over beta releases that are still buggy (I just reverted my AM7 back to 4.4.2 b125), and that to me is a deal breaker. But again - some people are content.

I'll say this though - CM12.2 or whatever it'll be called for Android M would go amazing with the AM7. With fingerprint reading natively built into 6.0, maybe we could see CM ROM's with a fingerprint scanner. My main gripe with the CM ROM's for the AM7 was lack of fingerprint reading (understandably, of course, given the nature of the way its built into Huawei's kernel). Oh well!

One year ago they promised Lollipop for January. So forget it.
[Ascend Mate 7 Q&A, Help & Troubleshooting] vonotny:
Possible :)
[Ascend Mate 7 Q&A, Help & Troubleshooting] vonotny:
The different hardware is a convincing point - considering this is (from what I've read) also what's keeping back Lollipop for so long.

I've been eyeing the Moto X Style myself, as well as the Nexus 6P (which I find far too expensive) and the OnePlus 2. I would miss the fingerprint sensor on the Moto, though ...
[Ascend Mate 7 Q&A, Help & Troubleshooting] vonotny:
That's what I'm hoping - that a CM-based Marshmallow ROM with fingerprint support will come to our phones. In fact, I can't stand EMUI and would prefer vanilla or close to vanilla Android - if only it were currently possible. Since the OnePlus 2 is impossible to get (at least at its official retail price) and the Nexus 6P is so damn expensive (almost iPhone money ...), I'm going to stick with my Mate for the time being ...
[Ascend Mate 7 Q&A, Help & Troubleshooting] alvinma:
No.

Don't expect Marshmallow for mate 7.

Just don't.
[Ascend Mate 7 Q&A, Help & Troubleshooting] armude:
Did you this leak?? It's a picture where there are the first devices that will get marshmallow(6.0), probably at the end of this year(i dont believe that part haha)
[Ascend Mate 7 Q&A, Help & Troubleshooting] vonotny:
Yeah, but is that official information or is it wishful thinking? My bet is on the latter.
[Ascend Mate 7 Q&A, Help & Troubleshooting] armude:
I cant tell, i only know that is a leak, but there are several news telling that huawei will update mate 7, mate S, honor 6, p8, and more, to android M, lets give them a try
[Ascend Mate 7 Q&A, Help & Troubleshooting] smilu:
I would say that the lollipop upgrade has been dumped away - and we will go directly to Android M6. Last known AL5 beta was B317 for the LT-09 - the betas came out every few weeks, now it's silent since the B317 wich was close to done - was in matter of days for the official release.

Also some sites report that Huawei said about AM6 update is coming much much sooner...and some of them even say Q4 2015

[Sprint Samsung Galaxy Note5] nycdarkness:
Traveling to china and was hoping to just bring one phone. Anyone know if I would get LTE on band 41 with the note 5?
[Sprint Samsung Galaxy Note5] nycdarkness:
Bump for help again. Gonna have to buy a 6s if I can't get any more info on this. From all the googling I've done I should get LTE on china mobile but would really not carry 2 phones if I don't have to.
[Sprint Samsung Galaxy Note5] Wasabi Sushi Cat:
I live in Shenzhen currently and it works in theory. The device can really register to the LTE network but signal can be very fluctuated when moving, since only one of the bands are compatible, and China is still on the way to establish a complete LTE network. China Mobile don't have UMTS network so I suggest you to use China Telecom's service with a EVDO service. It's more stable and have a quite good coverage especially in rural area.
[Greenify] crackers8199:
just installed greenify yesterday and have been playing around with it, pleased with the results so far...but i'm trying to greenify google maps and not having much success.

i get that only the donation version (which i'm strongly considering purchasing btw, just want to do a little more tinkering before commiting) allows for greenifying system apps...so i converted maps to a user app in titanium and rebooted - but maps still isn't showing in the app analyzer for me to greenify it. am i missing something? i see tons of people saying they've greenified maps, but i can't for the life of me figure out how to do it...

also (unrelated), what does 'don't remove notifications' do? i checked it but i don't seem to get any notifications when apps are hibernated (i don't get any notifications regardless of whether it's checked or not, actually)...
[Greenify] DB126:
Maps hibernates fine with the donate version ('nuff said).

'Don't Remove notifications' refers to notifications the target app has posted which could be dismissed by Greenify. Eg: new mail count.
[Greenify] crackers8199:
I'm sure it does...that doesn't answer the question of why it doesn't show up once it's converted to a user app. Like I said I'm considering the paid version, but I'm not sure why this wouldn't work as a user app...
[Greenify] DB126:
Who knows...maybe it retains some if its system characteristics. Donate version $3 USD and it does what you want.
[Greenify] crackers8199:
I still might...but the FAQ on google+ specifically says you can do it by converting to user app. It doesn't work. I'd like to know if there's something I'm missing, aside from "buy the paid version" (and if that's the case, they should update the FAQ)
[Greenify] crackers8199:
Nvm, after a bit of use maps showed up in the list. Greenified it now, we'll see how it works... :)

Firstly, a big thank you to all those members of this forum that post usefull infomation, whilst I don't post, I do find most of the posted info very useful.

A couple of questions:

1) Are T-Mobile going to offer a WM 6 Upgrade in the UK (I assume the O2 UK upgrade is official ?)

2) Have the issues with WM 6 and the Blackberry Rim software been resolved ?

Many thanks in advance :)

[P3300, MDA Compact III  upgrading etc.] Gajet:
Last I heard T-Mobile had said NO, they weren't going to give us an official upgrade.

Not that it's a problem, Network's own releases are always notoriously bad, look at the reviews of O2's offering for example, much better off with the software direct from HTC or a cooked ROM like one of Tom's B&B.

Sorry don't use Blackberry software here.
