Backlight problem/blank screen: any fix? - Sprint HTC EVO 4G LTE

Hey guys and gals!
I've got one of the rare white and silver Jewels, model PJ75100, and after seeing how well my Jewel runs on PAC-ROM 5.1.1 Lollipop, my girlfriend wants it for herself to replace her iPhone 5c.
Problem is... The screen isn't working.
It does boot up and run, but nothing shows on screen. I've even updated the firmware with the latest release Sense, but to no avail.
I haven't disassembled the phone yet, and I'm willing to tackle any hardware related problem I have to just to get this thing going.
Outside of one nick in the back cover, it looks brand new, so that's a plus. Not to mention that my girl wants a 2012 phone to replace her 2014 iPhone 5c, which I think is a big bonus.
Any help would be greatly appreciated, and thanks in advance.

Just bought a iRola DX752 7" tablet

I want to build a android 4.4 kernel for my iRola DX752 7" tablet (formerly known as a Kocasco M752) using Eclipse ADT etc. but I am practically a newbee at this. I figure if I brick it I am only out $50. It currently runs Android 4.2.2 with system updates that I can't count on bringing me up to more current releases, and it runs a Rockchip RK2926 Cortex-A9 CPU with 512MB RAM, 2GB internal SD and a 16GB external SD card.
I have rooted a smart phone without bricking it, but that was with a couple three premade kernels to update with and can not find any for this make or model tablet.
Tablet
Well my friend.. I can help you with that but just a single question.. Is the tablet good? No problems at all? If is good I will buy and we can make even ROMs together...
Just tell me if the tablet is good and what problems you encountered using it.:highfive:
does this thing come unlocked? How hard is it to root and is there any roms?
irola
Let me know if you make a ROM. I want to buy this tablet but it seems like it lags and its slow on the stock 4.2.2 ROM.
Very nice tablet
I purchased two for my kids and one came in the other day. I am very surprised about how well it is made. It doesn't feel like a cheap tablet. I would also be interested in a custom rom for this as well.

I ordered one for my daughter for Christmas. It is still in it's original packaging and I was lurking here to see if anyone had ideas for rooting it. From the specs it seems to have decent hardware so I am confident that it should perform well even though we haven't tried it out yet. I gave her one of my older Viewsonic tablets that's rooted and with a custom ROM. I may buy another one of these iRola tablets if I like the core stock install and then I will join you in creating some root magic for it.. :angel:

If you are seriously thinking of rooting this hit me up we can work together. That makes 3 of us working on it. I was trying to hack it to install windows 8.
Did anyone get anywhere with this tablet? Mine came in this morning. It's a little sluggish, but I have decent hopes for it.

Has this development went any further? I'd also be happy to test or help build in any way that I can.
I just got one of these
I just got one of these for my daughter, but it has the Jellybean that has trouble with Wifi... it won't connect to my home Wifi router at all, and drops the connection regularly at work.
So, I want to get a different version of Android on this thing. Has anyone succeeded yet?
I doubt it's the hardware, as I have friends who had the same problem on their phones until they upgraded their version of Android.
I'm unfamiliar with development, but would also be happy to test. From what I can tell, this thing has a memory issue. We need to get something lighter on it.

Put me on the list of people curious about development for this device. Just picked one up as a gift for a my sister and agree it seems a little more sluggish than I thought it would. Also the screen resolution is kind of poor and was hoping that maybe changing the DPI could help if it were rooted.
i haven't received mine
I order mine back on Nov 22, I haven't received it. I've been itching to root this. Ugh come on N MR send me my tablet. Has anyone have problems with NMR shipping before. ????
Just got mine. It's so sluggish...
I don't understand how, even after a factory reset, this thing is ridiculously slow. I have googled and googled but I can't find any information on how to root this device or even if it's possible yet. I really wanna downgrade the software to something it's more comfortable running. Maybe 4.0.4?
If you haven't received your tablet I implor that you contact NMR ASAP. They didn't send my fiances mothers 3 irola 7" tablets ordered later Nov. until yesterday Dec. 23.
I will also be working on this tablet as I just got it as a present from her So make that 4.
I also just bought this tablet (irola dx752) running android 4.2.2. I have never had a tablet before but it does not seem slow or laggy. I am familiar with linux (someone asked that earlier in this thread) and I am interested in getting into android development. Also happy to test (not intending to brick of course).

[Q] No. 1 N3 [Note 3 - Replica] + Cyanogenmod?

Hey everyone!
I couple of days ago I bought this phone from alibaba.com because I got a good price for it and the specs where decent, atleast for the price.
So far, it's a great phone. It has one bug though which is that sometimes, not always, the volume will go from mute to FULL and force itself to stay there. Like if you were to try and lower the volume, either via the phone menu, or with the side buttons, it would go back up.
This is kind anoying, and these spasms lasts for maximum 30 seconds, ie after 30 seconds you can normally turn the volume down.
But overall, good phone, would've been better if it wasnt doing that. Anyways, to my question.
I want to install Cyanogen mod on this phone. That is the reason why I made this thread, to ask for help/informationg regarding this process, wether its possible or not.
Here are some information I took from the "about phone" window;
Model Number: N3
Android Version: 4.3.0
Baseband Version: N3XXUAMDK
Kernel Version: 3.4.5-526212 [email protected]#1 tue aPR 23 23:00:57 kst 2013
Build number: N3_V1.0_V01_2013
SELinux Status: Enforcing
For specifications phonewise visit this link; turns out I cannot post links yet, but just google "No.1 N3" and their main page will pop out and there are the specs. (I have the 1gb version btw, on their page it costs 199 i think)
So, is this possible? I feel like if this is some kind of software failure, installing cyanogen/or any other rom might fix it.
Also, if it isnt going to fix it, I'd still want my phone to have cyanogen if possible.
Thanks in advance everyone!
issues
Just got this phone in the mail....looks identical to note 3 butttt ...it just isn't connecting to my mobile network. Very frustrating
Radio frequencies are correct etc. I'm on Telus network, I did get a connection for 2 mins and then gone.
On the manufactures website the specs indicate it comes with 4.2 but mine has 4.3. Wondering if the 4.3 is an issue.
The status bars are all grey with a red x above them. Any help would be awesome.
Thanks
Porting cyanogen-mod is possible, but just in the way, that almost nothing is impossible.
There is no cyanogen-mod porting so far for the 6589 phones, so you have to port every driver and everything by hand.
If i were you, i would try to flash the newest no1. n3 rom and look if it runs better.
At my No.1 S6 the last firmware solved always every annoying issues from the beginning.
I haven't found a thread about this phone here yet, so i cant give you a link to the latest firmware.
I saw that needrom.com has a rom for the No. 1 N3 so you who had a problem with your phone could maybe use that.
The volume error has seem to have dissapeared now for some strange reason?
Anyways I'm happy, but I still want more discussion about this phone. It's very good actually.
Thanks to the one posted here.
Also, I have no experience with android development so me porting cyanogen to this phone would not work at all
I think i will get my N3 next week.
Now i'm on my No.1 - S6...

From where did you buy it?
Also, please post here with your thoughts of the phone when you get it!
I buyed it second-hand, originally it came from tinydeal.
Is here a general discussion thread about this phone?
I got mine today, with firmware from 2013-11-18, and the camera-pictures are very noisy.
I guess this is an issue of the camera-drivers.
How are your photos?
So no.1 n3 dont have any custom rom

I think something will come up though sooner or later for the N3.
So, has anyone mixtured and experimented with this device?
Looking forward to hearing about your devices.

American noob here. XDA Developer Boocy has some interesting info: http://forum.xda-developers.com/showthread.php?t=2438752
I received my No.1 N3 (the lower end $179 version as a matter of poverty) with the black boot animation. I believe it shipped with the updated ROM version on http://www.needrom.com/mobile/no-1-n3-2/ . I didn't use Boocy's backup and root tutorial because the cpu name has a T at the end of it (MTK6589T) and this is Android 4.3.0... it seems this phone needs some time on the market before developers see a demand for custom ROMs and we can get a straight forward fix for the GPS issues.
MTK Droid Tools reference in Boocy's post rooted the phone with the superuser button and SuperSu (after spending 8 hours researching why my MTKDroidTools didn't have a root button as seen in some image searches).
As a noob who spent the past 3 days on this phone, MTKDroidTools rooted the phone, but none of the GPS "fixes" or apps I've found work... and GPS is essential for my job. I've researched other custom ROMs but found nothing. I"m stuck at attempting to go back to stock with the needrom.com version posted above (because I didn't know enough about creating and flashing backups until it was too late).
Please link any relevant guides that have helped you in working with this phone. Keep on Google and let the rest of us know when this phone gets the attention it deserves from the developer community! (Thank you developers!)

I've installed the first version of the stock rom from needrom.com... black boot animation. I'm installing the update, which is what I believe came on the phone, black boot animation. I don't think I've seen the white or know where it came from. I'm not sure where the boot animation is stored on the phone, but I'm assuming it is attached to the ROM and when you flash you get a different animation?
I forgot to mention I have MTK Droid Root & Tools v2.5.2... and that in rooting by pressing the SuperUser button, I replaced the HBOOT screen with CWM (when you press volume up, power on, and home screen button during boot). Not sure how I did that, but I'm still trying to figure out where the kernel, rom, and recovery screen and recovery ROM are and which one gets replaced with what. Guides appreciated.
Sorry, if GPS is so important for you, i'm afraid to say you got the wrong phone.
No Fix will make a REAL good GPS, because the antennas are not really good.
With EPO and AGPS on, my phone gets a hot fix in less than 10sec, but navigating with maps is nearly impossible.
Finding satellites inside a car with chromed windows is more than hard.
Nearly all china-phones, but specially the clones have bad gps, and i think they always will.
Better buy a better phone than a cheap samsung galaxy grand or something.

[Q] If I get a Nexus 9, what are the odds of it getting defects?

I'd really like to get a Nexus 9, but it seems like there's no end to the hardware issues people are having. I know HTC has said they've fixed the issues, but is there anyone here who has gotten one in the past few weeks, and if so, were the issues still present? I don't want to get into a loop of sending it back to HTC and them sending it to me with nothing getting resolved. Should I just get a Galaxy Tab S and deal with TouchWiz?
edit: I suppose the title should read "having defects", not "getting defects". Oh well.

Did you get those Nexuses recently though? Not getting updates would be the downside to the Tab S, I agree. Lollipop is so nice, but TouchWiz would cover it up even if it were updated.

I ordered 2, one white and one black. White one ran out of battery and won't charge or turn back on, tried several chargers. Black one had the "usual" defects... visible light bleed and press-able gap in the back cover. RMAing both, props to amazon for awesome return policy especially during the holidays.
have a white 16gb model ordered 2 weeks ago from amazon. nothing wrong.
Picked mine up today from Currys UK, White 16gb, No issues.... Can't see any light bleeding from the edge of thge screen or atleast no more than my Nexus 7!... It gets warm at the top whilst in use but with a case you wouldn't notice it. The white is my favourite as i think it looks more premium with the silver metal edge.

Guess I'll try getting a white Nexus 9 then, it seems people have the least issues with them.

Dude this actually helped me a lot, I am looking to get a nexus 9 from currys too.
Still can't decide whether to keep my Z2 and get a nexus 9 OR just sell Z2 and get a note 4 :/
All these issues with the Nexus 9 are making me uneasy
At the end of the day, any issues you have you can march it straight back and get a full refund. Like I said I'm happy with mine although one of my volume buttons is a bit more sunk than the other I did the bleed test last night and its fine, going by the thread on release codes mine is one of the release ones!

[Q] Glitched screen

The issue is about screen getting glitched output. I don't think this is a software issue. There is some hardware issue because I tried flashing 5.0, 5.0.2, 5.1.1 still problem persists. Randomly at any time the glitched screen like seen in the pic is popped up in between from any app or just home screen. First i thought some app may be causing this but its not the issue. I deleted all the apps still this problem stays.

Hmm thanks
I've been spreading word in xda about the same issues. If you search the Q/A forum, you'd find too many people having this issue. This is due to a faulty GPU when the device heats up excessively. Recurrent issue in a Nvidia chip. If you bought it recently within 30 days on eBay, I'd suggest you return your device and claim your money back. Else I'm afraid you are screwed since neither HTC nor Google offer warranty if purchased through unofficial sources in India.

Now that what i feared. Let me see if they will take this back. Anyway thanks for the info that was really helpful
Unfortunately your Nexus 9 is toast. This happened to my first one and it got so bad it would happen during boot and I couldn't get any further. HTC was next to unless. Delt with them for 3 weeks trying to get an exchange. They are clueless. They wanted to try flashing stock image over and over. I'm like dude, I'm a Nexus owner. Don't you know your customer base? Anyways, best buy agreed to exchange it for a new one if I bought their premium protection plan, which I did gladly. But it is a hardware failure. There's no fixing it.
I just had my day one nexus replaced for the same issue last week. Had been getting worse for months. I called warranty service, told them about the screen corruption/noise/lockup issue needing a mainboard replacement. sent my tablet back and they overnited me a replacement that appears brand new (mine was mint condition as well). Still has lightbleed and so-so buttons but works great and I've put it through its paces. Only thing I had to tell them was the serial # but I was the original amazon purchaser.
Is it a newer build date than your original?
I had an experience similar to techiedj's. Got my old N9 replaced by Google a few weeks ago. Replacement looked brand new, but is actually an older built with slightly crappier buttons. Curious how long this one will last now...
These are the symptoms that I saw: At some point the screen started to flicker for a few seconds, then froze, and slowly turned black. After a few second I could turn on the display again. The area on the back next to the camera had become hot, but apps that read the sensor values did not really show high temperature (50 degrees or so). A good way to trigger it was to open Chrome and open multiple pages in a short time (opening different links in new tabs). Surprisingly, seemingly GPU intense games were less affected by this than Chrome. Factory reset did not help, even when I skipped the initial login/restore apps step.
Hopefully they aren't all doomed to this fait at some point. I have best buys replacement plan now, so this this can die early Jan 2017 and I'll get whatever the new Nexus is then.
Not really. HT4AJ I think it was, HT4AY on this one.

I went from an AE to an AF. Hard to believe best buy still had old stock, but I guess they didn't sell a lot of these. Buttons are nearly perfect on this one though. Way more tactile and the volume up isn't sunken in.

Lock Screen Removal/Bypass?

Just curious if anyone knows of any method/software to get past the lock screen on an LG G5 (Rogers is the carrier in Canada). My little brother recently passed away (he was 29....) and we are wanting to get any pictures we can and make sure we take care of his estate/accounts. I have found the "Dr. Fone" software by wondershare but it looks super sketchy and i've yet to find any confirmed cases of anyone using it successfully to remove the lock screen on a device. It is completely stock and is still on Marshmallow (the Nougat update is pending). If anyone knows it would be greatly appreciated

So sorry to hear a bout your lose. I know the pain, brother died 8 months ago And sister few years back. Rip to your brother and my siblings.
But back to your question. Did you try taken out sd card? Most stock and 3rd party cam apps go to pictures on sd. I am sure you google already. As you can see there isn't many options for lockscreen bypass.
Later on today I will test that program out for you and report results.
Bump help this guy out people. Maybe someone knows more?
Question could he call google and supply proof of relationship and death of owner. Then google would provide password? Doubt it, just curious.
