Hi All,
I have a G Tablet and have gotten myself into a right mess.
I had bricked the device to a point where the logo splash screen would appear, but it wouldn't progress any further. I couldn't get into CW restore or anything.
I got the unit into APX mode, installed the driver and managed to get a connection.
Then I accidentally ran the "nvflash_1gb_lcd.bat" file.
Now the unit doesn't want to even go into APX mode, so I can't reflash the unit with a different boot/restore/system img set.
Is there any way that I can get back from this?
If so, how do I go about it?
Mark
Take it back
Return it and tell them its defective.... they will have to replace it. I mean especially if you show them it won't turn on properly.

Are you serious? You screw things up and then hand the mess over to someone else? And some people wonder why return polices at certain places are so crappy for the rest of us.
To the OP, please don't do what alynch75 suggested. I would help you if I knew how but unfortunately, I don't. Hopefully, this bump will get your thread some more attention from people who potentially do know what to do.
If you can get it back into APX mode (and you should be able to), then try bekit's nvflash image:

If you cannot get it into APX mode, then you might be SOOL.

Nah, I wouldn't do this even if I was in the US. I am in Australia.
We'll see how we go.

Not to worry. Did you get clockwork recovery installed? Go to WWW.droidpirate.com and go to g tablet section. You,LLC find all the files you need there. Had the same issue today and got it resolved following the tutorials there! If not maybe we can setup a remote session and get it resolve. Send me a pm and we can go from there. Don,t lose heart, your device is not bricked!
come on i dind't know he screwed it up. I thought this was something that the device was supposed to be able to do. I am new to android... give me a break .. i didn't mean any harm....
I think I posted this in the wrong forum, I suppose I was a little confused on my phone
I have a US AT&T version of the i727 Skyrocket. I think i accidentally flashed an improper kernel:
http://forum.xda-developers.com/showthread.php?t=1369977
I didn't realize I was browsing the wrong forum *sigh*.
Anyway, when I went to reboot after installing the kernel in CWM, I get a black screen. If I hold down both volume buttons and plug in USB, I get nothing. It doesn't seem to put it in download mode. There, it doesn't get recognized in ODIN.
What are my options here? Would a "jig" actually do anything in this case? I can't tell the scenarios it can actually recover from and not.
Hard brick, its done
Jtag or send to samsung

If it does absolutely nothing, i'd say you bricked it which is quite possible if you flashed something for another phone. I don't think a jig will do you any good, based on things i've read before. Not 100%. Maybe someone else will give you some better input.
thanks for the replies. I can't get it in to download mode at all, so I'm afraid it's hard bricked.
Are there any guides to doing the jtag repair yourself? I'm pretty tech-savvy and comfortable opening up the phone, etc. I could get my hands on a jtag unit.
I just don't want to keep bricking it and sending it out for another $50. I'd rather have a solution where I can fix it myself.

I'd hope not to, but on my first try I bricked it. I've never bricked my Nexus S after a ton of crappy kernels. Sigh...
Doesn't look like anyone has figured out a homebrew JTAG solution.

Well, jtag for this phone was just made possible only a month or two ago. There may be a guide somewhere, but I dunno. You flashed something from a completely different phone, any time you do that you are pretty much guaranteed a brick. Just pay attention to what you're doing, man. Read more and flash less.

Right, understandable. Lesson learned there.
I can't tell if this is legitimate or not:
http://www.jtagbox.com/2012/03/page/2/
$50 isn't too bad. Obviously doing it yourself, if you could, would be better. I'd be on the safe side though and have mobiletech (i'm assuming you know about them), do it.
This is going to be long!
If anyone has insight to this would be appreciated
Precursor: I am on CM9 nightly (7-27-12) with 6.0.1.0 non touch recovery (NS4G)
So last night I go to open my opera web browser and it would flash like it would open and instant close (no error message). I say OK thats weird and decide to reboot. Upon rebooted I am greeted with never ending amount of FC's from every app and service imaginable. I again say OK EXTREMELY weird and decide its time to restore my backup from yesterday.
I reboot in recovery and what do I get greeted with? Unable to mount /sdcard! Long story short after scouring google for about an hour I find that if I do a fastboot oem lock/unlock I should get back up and running. Thankfully that works and I install the newest 7/31 CM9 nightly.
I wake up today without my phone alarm going off when it should. Weird huh? I go to open the clock and get a FC from the clock application. Reboot and it works just fine. OK weird again.
Go to work and leave my phone on the counter to help a customer. I come back to the desk and my phone is in recovery mode? Uhhh what? I reboot the phone and it says "encryption unsuccessful" and the phone needs to wipe data and reboot to continue use...
I decide WTF why not, not like I can use it. At this point I'm worried though. The phone reboots to recovery and I guess does a data wipe (takes 3-5 mins) and reboots. Now I am stuck on the CM9 bootscreen and won't go past.
I have some ideas as to get the phone (hopefully) back up and running. Just curious what this sounds like to anyone more knowledgeable then me (especially the part where it tried to encrypt my phone without me touching it!)
Any thoughts or help is appreciated!
Edit: I tried copying files to sdcard from recovery using mount usb storage. The files copy over and as soon as I leave the mount menu and go to install the zip files WHICH I SAW ON THE SDCARD they ARE NOT THERE anymore.
Edit2: It still lets me install the CM9 7/31 nightly which I had saved on the phone yesterday. Even after wiping everything and reinstalling the ROM I can't get past the CM9 bootscreen
Edit3: Tried fastboot, odin, nothing works. Even after odin I still get the CM9 boot screen. Pretty sure something is messed up to the point of I need a new phone. FML!
YESS!!!
YES I WANT ATTENTION.
I Have exactly the same. Mother of smartphones Somebody help us!
Its the internal Memory thats messed up yes, But Please somebody fix this Bullcrap. We don't have the knowledge but I will gladly donate to you who fixes it!
I just bought a brand new screen for my phone and I don't freaking want to buy a new Phone At the moment, So if you find a way to help us then let us know since that could be lifesaving right now.
Pretty sure I've given up. Everything I've tried has failed... looks like it might be gnex time.

I HAD THIS SAME EXACT PROBLEM
Temporary solution: heat the phone up with a hair blow dryer. get it hot but not so hot that it melts things. it will be able to boot up and work. I used this method so i could copy my sd card to my computer and wipe everything off
Permanent solution: turn your phone in for repair. there is no remedy to fixing this. apparently the circuit board or chip is bad and you can't fix it.
Luckily I had best buy black tie protection and I am waiting on my new replacement phone.

You can have mine lol x) And Yep i fix computers for friends and so on their friends and this sounds like Nvidia was behind the chip... xD
It wouldn't matter who actually makes a chip if the heating it up is a temporary fix. That is a OEM issue. Basically think xbox360 rrod with the warped boards the solder melting/failing and the chips get loose etc.
Unless heating up failed flash storage temporarily makes it work. Which I doubt is the case but don't actually know. Brings back memories of putting failing HDD drives in the freezer though.
Well this is my official goodbye to the Nexus S forums (not like anyone cares haha). Just got my shiny new Galaxy Nexus. Have a great night everyone and happy modding!

Unfortunately that is good only if software screwed up your phone. In my case and I'm sure others when it is hardware failure, that won't work :\
Hi all,
I bought a Chinese tablet from Focalprice, waited three weeks for it to arrive only to find there's something wrong with the screen. It's really washed out. When tilted it's light at the top and dark at the bottom. If I flip it over it's dark at the top and light at the bottom! If in Portrait it's noticeably brighter one side and darker the other. It's just... weird!
Now, don't get me wrong, I wasn't expecting Samsung quality when I bought this for sixty quid, but I was expecting to be able to see whatever's on the screen! I tried playing Candy Crush on it last night and I managed about 5 minutes before my eyes went wonky!
I've attached some photo's so you can get an idea (sorry they're not great!).
I've opened an RMA with Focalprice but they're just jerking me about so I thought I'd see if it's fixable.
Here are the details of the tablet:
Make: V100q
Model #: rk30sdk
Android version: 4.2.2
Kernel version: 3.0.36+ [email protected] #442 Tues Oct 22 12:40:31 CST 2013
Build #: rk30sdk-eng 4.2.2 JDQ39 eng-edward.20131105.205030 test-keys
I was going to try one of Oma's roms but I can't even get CWM to install properly.
*Sigh* I only wanted it for comic books. :crying:
Any help gratefully received.

Sorry, dude. It seems You have to learn the hard way. As a german saying goes: If You buy cheap, You will buy twice or triple.
Have you rooted it yet?
First off, I'd suggest you inquire with any other owners of this same tab, and check with them if only your device is faulty, or if that's the case with every model of that tab.
If everyone else owning this tab has the same problem, most probably its a software problem. You might wanna play around with root brightness adjusters, and/or Chainfire3d (CF3D is not officially supported for your android version, make sure to take backup of stock rom before doing anything!).
Your best bet would be to raise hell with Focalprice. Make sure to do a full unroot if you're sending it in for warranty!

Thanks, that was really constructive.
I'm sure I'm not the only member who's bought a Chinese tablet, I only wanted to know if I can fix the problem or not before I try and send it back. I realise it's a matter of "You get what you pay for" but reviews seemed to suggest this was a good tablet for it's price.

Thanks mate, this is more what I was hoping for in response!
I have rooted it, but couldn't find any program to help with the problem. Could you recommend a brightness adjuster?
I can't get CWM to work properly and ADB just refuses to see this tablet.
I've been playing around with devices for around 10 years so I'm not a n00b with these things, but this tablet just won't play ball!
I'm trying like mad with Focalprice, even said I'd so a chargeback, but they're not budging!

Haha, you're welcome.
RootDim works fine, you can find it on the Play Store.
Is your tab a MediaTek device? If so, which one? You will need MTK VCOM drivers for chinese tabs which you will have to install manually. I will provide links if it's a MTK device. Also, if it's an MTK device, you can use rua1's auto-CWM builder to get a fully functional CWM yourself in a minute
Thanks, will check out RootDim.
How would I find out if it's MediaTek? The info in my first post is all I can find.

Download the latest SP Flash Tool from here. Insert your stock rom's scatter loading file (will be in .txt format) into SP Flash Tool, and it will tell you which MTK model it is.
Should look something like this-
Once you find that, let me know. Please do reply by quoting my last post, so that I get a notification and can get back to you asap.
Tried RootDim but it just darkens or lightens the screen, doesn't help with the colour. Anything else I can try?
Edit: Oops, didn't see your reply! Will try that, but like I said, I can't get my PC to see the tablet so... I'll get back to you!
Hi again,
I know it's been some time since I started this thread, but hoping you (or someone else who's looking!) could still help?
I finally worked out how to get the scatter file and this is the result I got:
No matter what I try I cannot get access to ADB Shell with the tablet connected via USB so I downloaded ADB Wireless from Google Play and was able to connect that way.
I've tried installing CWM from here: http://androtab.info/clockworkmod/rockchip/install/ Tried from SD but no go. Also tried using a terminal on the tablet and root shell, again no luck.
I think I've discovered that to enter recovery I press PWR and Vol- for 2-3 secs and it enters something, but the screen's blank. It'll show up in device manager as "Rockusb" but I still can't get any programs to see it.
I've tried half a dozen different drivers and none seem to work. Am I stuffed? Or is there something really simple I'm missing?
Cheers!
Edit: Little update since I posted. I decided to pop the tablet open and take a look at the actual chip. Turns out it's a Rockchip RK3168 and not the RK3066 I thought it was (based on information I gathered via t'interweb). Not sure it's that big of a deal, but thought it was worth mentioning in case it is!

Got the Note 20 Ultra 5g a week ago used from a decent reseller. Today I got the black screen of death. Stock firmware.
I want to return the phone while I have the chance, no interest in trying to fix it. It is password protected but I would ideally like to hard reset it before it goes back. Can anyone tell me how when I can't get the screen to work?
Phone beeps etc so I think is live.
The power button + vol down does give a vibration after 10 seconds but never gets to a Samsung logo.
Power button + vol up does the same.
Tried connecting to a pc, no change. No dex message on the PC.
If anyone can tell me how to do this reset so I can wipe it for peace of mind I would appreciate it. Thanks in advance.
Edit; I removed the sim cards and then the PC detected the phone, and offered to install Dex. If that helps.
Ok before you do anything else. Stop. If you void the warranty by changing anything you can't return it
You need to find a trusted phone store near you or call the support number for the phones manufacturer
Thanks for the advice. Appreciated.

So I did a little more digging and found a website imma give you the link I'll read through the rest of it, and advise you what seems safe but in the end what you do is up to u
So you need to go into recovery mode and try something simple what you are gonna wanna do is find where to wipe the cache partition and that should solve it. but I'm guessing you can't get into recovery otherwise you could factory reset it there

>>I'm guessing you can't get into recovery
Correct. The phone is goig back to the seller as it is within the return window. I don't want to mess with it. I think that was good advice. Did Samsung ever say if they resolved this issue properly? It puts me off this model. Very expensive phone to suffer such a problem.
