[Galaxy S 4 Q&A, Help & Troubleshooting] CorruptedSanity:
I had horrible burn in on my Note I.

Could see the full keyboard like a shadow.

Same with the top bar. Could see the battery icon & alarm icon.

finally got it replaced (screen only).

Burn in came back though.

Screen was noticeably brighter when replaced.
[Galaxy S 4 Q&A, Help & Troubleshooting] Mandeep148:
What burnin looks like? Mura effect?
[Galaxy S 4 Q&A, Help & Troubleshooting] msavic6:
Its like a faint blue hue over the affected area in the begining stages of burn in which isn't noticeable unless you go into a display test app and look for it.
[Galaxy S 4 Q&A, Help & Troubleshooting] MichelN:
Go to a local shop and look there (those demo units). They are all burned in, i owned a galaxy s1 and mine burned in as well (screen was on for 30 min!). My little sister has a S3 and is using whatsapp alot with her friends, the entire keyboard is burned in and the top bar too.

Hello XDA Developers community!

I have this newly rooted tablet, it is an Alcatel OneTouch Tab T10. I rooted it using the tool bin4ry had, and it is now rooted. My classmate introduced me to this stuff and gave me the courage to give it a go, and now he's recommending me to flash ROMs and try out what suits my needs.

However, I found out too that I need to back-up my stock ROM first. Well, I want to back-up my stock recovery as well. I downloaded TWRP Manager from Google Play Store, and now I'm wondering how could I backup my ROM and recovery?

If you can recommend me other tools and tutorials etc., I'm willing to give them a shot. I'm hoping for an immediate response from you guys. :D :angel:

Thank you very much. I'd appreciate your help so much.

I've got a problem with my car kit and the bluetooth of Qtek 9090:

When I shut down the PDA the bluetooth shut down too, so the car kit (a DriveBlue) disconnects from the PDA and you loose the Bluetooth connection (until you turn on the PDA again).

I¡hve got the 3500 bluetooth stack installed.

Does anybody know this problem?. And it's solution if possible.

Thanks a lot!

I just bought triangle away from the app store used it to reset counter and system status workaround my device is now official thanks to all that.

So i uninstalled it to not leave it on my phone just in case someone is playing with my phone and messes with it.. and i receive an email saying it has been refunded!?

Seems odd that just from uninstalling it on phone i get an instant refund, has anyone had that before or is that how the system works?
[Galaxy S 4 Q&A, Help & Troubleshooting] stierney:

[Nook HD, HD+ General] samomamo:
Hi, I changed the DPI from 240 on original CM10 to 480 or 320 (320 I think is much better) and the NHD+ is running much smoother and all the icons, fonts, look right.

If anyone interested try. With root explorer go to system, find build.prop, open it with text editor, change the density DPI from 240 to 320 save and exit, reboot and done. Or get a density changeling app from Google play.

Sent from my HD+
[Nook HD, HD+ General] leapinlar:
Maybe that is why I never suffer any of the issues that others suffer. I have run at 320 since the first verygreen CM10/CM10.1's came out months ago. It is just the way I like it since my first tablet was a Galaxy Tab 7" and the icon and text sizes match that.

Sent from my Nook HD+ running CM10.1 on emmc.
[Nook HD, HD+ General] srgibbs99:
Wow, after running on 240 for so long, changing to 320 makes everything seem magnified...like, so my grandma could read it. :laugh: Also less real-estate to work with.

I think i prefer 240, but thanks for the tip.
[Nook HD, HD+ General] rushless:
I guess a one third increase would look pretty big. I like the current size, but can appreciate others liking bigger. Not noticing the unsmooth issue with Nova, but DID notice it with the default launcher in CM 10.1 and also with stock 2.1 (even when using Nova).
[Nook HD, HD+ General] verygreen:
We are running omap4470 at the far end of it's capabilities, it seems. Same sort of issues are present in Kindle Fire HD 8.9 (also omap4470 chip with 1920x1200 panel).

There are no problems in stock launcher on Nook HD that has same 4470 chip, but much smaller 1440x900 panel.
[Nook HD, HD+ General] killersloth:
It's a lot more pixels to push around, I noticed it on the HD+ as soon as I picked it up compared to the HD.

Usually even overclocking the CPU has little effect, but if we can oc the gpu and make it scalable it might actually make a difference.

I still need to learn more about omap chips, there doesn't appear to be a freq table like with msm chips, maybe I'm looking in the wrong places though. Can't even find any relevant commits on github, but again I'm probably looking in the wrong places.
[Nook HD, HD+ General] rushless:
Tegra 3 has the same issue, based on TF700 performance and Anandtech analysis. They actually found the 4470 more capable as far as cpu (this explains why HD+ is better with MAME) and for Flash and web browsing.

I prefer the HD+ with CM over the TF700 and stock Asus firmware. Seriously, and I am a picky person.
[Nook HD, HD+ General] verygreen:
it's in ach/arm/mach-omap2/opp4xxx_data.c, sadly a lot of them are running from a fixed clock so there's no easy way to actually bump them.

If we switch dpll_per clock for dpll_core for clocking bb2d and sgx cores, that should yield about 4% boost, that's about the easiest thing I see, though so far kernel does not want to agree with me about changing the parent clock ;)
[Nook HD, HD+ General] jpisini:
Anyone know if it is possible to change DPI on rooted stock?
[Nook HD, HD+ General] CubeCloudOS:
On my HD I had ROM Toolbox I used that to edit DPI while on stock. When I reboot the device however was still the same. I would suggest a app from google play since you have root.

"dpi changer"
[Nook HD, HD+ General] leapinlar:
Yes, look at my HD/HD+ stock tips thread linked in my signature (see item 7). You edit local.prop.

[Nook HD, HD+ General] blast0id:
doesn't changing DPI affect the ability to install certain market apps? I know on some phones it does...
[Nook HD, HD+ General] jpisini:
It certainly can, on my last tablet the dpi I liked made most apps incompatible. I would just grab them on my phone and then use titanium backup to make a copy for the tablet.
[Nook HD, HD+ General] TonyBigs:
I gave 160dpi a try. Text gets *really* small.
[Nook HD, HD+ General] samomamo:
If we use standard dpi's like 240, 320, 480 then go top settings/applications find the play store and clear the catch, then open play store and that's all it shouldn't be a problem.
[Nook HD, HD+ General] padawan_lp:
thank you for this tips, I'm really liking the tablet at 300 dpi.
[Nook HD, HD+ General] Kevin43:
Be careful doing this on stock with apps like DPI Changer. My HD+ went into the boot loop and restored itself to factory, now I have to go through the hassle of rooting, redownloading all my apps and stuff, and setting everything up again.

i set the hd up for 320. works great for flipboard and pulse. anybody try anything else that works in-between 240 and 320 that works well for the hd. im not to familiar with the standard numbers on the 7 inch tablet
[Nook HD, HD+ General] cenbit:
Got an error while changing the DPI. It requires a root access mode. I am running CM11.
[Nook HD, HD+ General] leapinlar:
Just set your file manager to root access mode and change the default 240 in build.prop to something higher. You also have to set /system to read/write mode.

I use 300 for my HD/HD+.
[Nook HD, HD+ General] lmacmil:
I thought DPI was a function screen resolution and the size of the screen. How can that be changed in software without the effective screen size shrinking?
[Nook HD, HD+ General] leapinlar:
I'm not sure of the total mechanism, but I assure you it works.
[Nook HD, HD+ General] Tzul:
You're right, but the dpi value in Android is basically just a scaling factor. If an app would like to display an icon that should be half an inch in size on the display, regardless of the physical size of the display, then it could use dimensions of 0.5 * dpi pixels. Now if you manipulate the dpi value, it's obvious that you can increase or decrease the size of things that are scaled like that.
[Nook HD, HD+ General] josim:
I have been disappointed with the lag I have been experiencing with my HD+. Bought a Chromebook and this thing is quick going thru web pages.

I made the adjustment to 300 DPI and my HD+ doesn't feel laggy anymore. Doesn't compare to the Chromebook for speed but a nice improvement. If you feel you HD+ is laggy, give this adjustment a try.

I want to increase battery life but wonder if it's noticeable.

[Sprint HTC One (M7)] gk1984:
I use it with just couldn't and display checked. Get great battery but it also helps reduce the overheating problem slightly. I don't notice any difference in performance whatsoever.
[Sprint HTC One (M7)] Vincent Law:
To be more accurate, each user is different. The phones are identical.

Power Saver mode will not save you any remarkable amount of battery unless you are maxing out the CPU or GPU (like playing games). Since what it does under the cover (besides what it advertises in the options) is downclock the CPU, this can actually be a detriment to battery life. It is better for battery life for the CPU to run at max speed for very short periods, and then go to sleep. It uses more power by running slower (and thus staying awake longer).

Again, it'll take a lot to really notice a change in either direction, though.
[Sprint HTC One (M7)] Rirere:
Correct me if I'm wrong, but the jury's still very much out on race-to-finish style processor governors. Sometimes they do well, sometimes they do badly. Either way, it depends on use case.

I would also hazard that it's very much an oversimplification to say that the phones are "identical." It's hardly unheard of for different production batches to use slightly different components. However, the impact from this is probably negligible compared to variations in user habit (and if it's not, then someone in QC/QA needs to go).
[Sprint HTC One (M7)] Vincent Law:
Race-to-finish is pretty much the de-facto standard for every decent mobile device right now. It's even getting pushed onto laptops and their associated CPUs (like Haswell).

And I don't think it's an oversimplification if the differing components are only ones that are using on the order of micro-amps of power. They're not using different spec CPUs or something. That would be insanity.
[Sprint HTC One (M7)] SkinnyBiggs:
Thanks Vincent for specifying that for me, I guess it's only roms because I have heard that each phone acts different. But this is new to me the phone uses more battery when it's at low speeds? I usually underclock to save battery while screen on as well as during sleep.
[Sprint HTC One (M7)] Vincent Law:
When your phone is asleep, underclocking does nothing, because it's not really even running at all. This mostly applies when the screen is on as well, for any cores not active. 0mhz > any underclock you can manage :P

[Windows RT Development and Hacking] netham45:
All it does is add the signatures for the debuggers and tools in the HCK to the secureboot whitelist. It's required to use CDB and the like.
[Windows RT Development and Hacking] bfosterjr:
Interesting. That doesn't quite match up with what the documentation states. Unless I'm misinterpreting you.. or the documentation?

Cheers!
[Windows RT Development and Hacking] netham45:
From my understanding of the tool it has the capability to do various things like disable secureboot or add whatever cert you want, but it requires a different .p7b from MS. The only p7b we have enables the HCK .exe's to run.
[Windows RT Development and Hacking] mamaich:
Yes, the tool just takes a policy file and processes it. The only working policy we have - is that adds a prerelease certificate, so that debugging tools from HCK 8.1 can run.

It can't directly disable secureboot itself, but if we'd have such a policy file - this would be possible with this tool. I've even wrote earlier what cert should it contain (info is from MS docs on secureboot), but, obviously, as the policy file is signed, we can't make it ourselves.
[Windows RT Development and Hacking] Myriachan:
Sigh... I was hoping that this information wouldn't get out prior to 8.1 retail.

I don't think that the .p7b file is itself signed; it's simply a certificate container. I did find out that there are 3 policy modes in SecureBootDebug.efi, and which is used depends on 16 particular bytes of the .p7b file. I don't know the .p7b format, so I have no idea what those bytes are.

I'm not sure what exactly SecureBootDebug.efi is validating in the .p7b file. It does do some sort of signature check.
[Windows RT Development and Hacking] mamaich:
It is signed, trust me. It is not an "ordinary" P7B, but a policy container signed by a KEK. It can be opened by a certificate tool - just export the same certificates from it, you'll see the decreased size and the new P7B would be failed by the device.

HCK in "SecureBoot" directory contains other similar files, but they have P7 extensions and signed with a test key, so they can't be processed by our devices.

And I think that SecureBootDebug.efi does not validate the policy file itself - it probably passes it to UEFI as is, and UEFI code validates and parses it (but this is just what I guess, I have not decompiled it yet).

Just for info - here is an article which describes what PK, KEK, DB, DBX are: http://blog.hansenpartnership.com/the-meaning-of-all-the-uefi-keys/

Our SecureBootDebug.efi - updates the DB keys in UEFI. You can use the Get-SecureBootUEFI powershell command to dump the DB before and after the tool.
[Windows RT Development and Hacking] Myriachan:
I read some UEFI documentation and am wondering something. According to it, updates to Secure Boot variables are signed with the Platform Key (PK). Updates have either a timestamp or a counter on them to prevent replay attacks. The timestamp is included with the signature.

Doesn't this mean that SecureBootDebug.efi has the PK's private key embedded somewhere within?
[Windows RT Development and Hacking] Myriachan:
You can use PowerShell to determine whether the SecureBootDebug.efi policy has been loaded: Get-SecureBootUEFI will return {639f31b2-d82f-4c0b-9fcc-6f51db62377a}.
[Windows RT Development and Hacking] mamaich:
No.

The tool updates the allowed certificates in DB, and its policy file is signed with KEK key (the MS one, as KEK also contains Asus keys in my VivoTab), so it is accepted by UEFI. I don't know whether it uses a timestamp or a counter - but it can be uninstalled and then replayed.

Microsoft does not have PK keys for devices (except for surface) as PK is used only by the hardware vendor. And the only usage of PK is to update KEK (or to update PK itself), so MS can't update KEK or PK on anything except their own Surface. But they can update DB and DBX anywhere.

Edited:

Just looked in .efi file - it has some certificate embedded. So I may be wrong and the file signature is checked with that cert, not with KEK. More looking is necessary.
