[Micromax A89 Ninja] DAC324:
It is, in my opinion, a bug or at least a missing feature in all versions of the SP Flash Tool.

If you are forced to flash a ROM using "Firmware upgrade" (because of that dreaded "PMT changed for the ROM; it must be downloaded" error), the NVRAM contents will be damaged.

What the trick described here does is re-install two working files from another phone.

If you want to do everything correctly, you would have to do a backup of the NVRAM before even starting SP Flash Tool. Unfortunately, it does not seem to be easy to accomplish. My Doogee Valencia DG800, for example, is not recognized by MTK Droid Tools although SP Tools work flawlessly with that phone.

Kind regards,

Not working on MT6580, with Marshmallow... the WIFI file is too old, you need a new one, I found one online unfortunately I am unable to post the link here yet, but I think you can get and upload a recent one from many phones, if you hexdump it instead of 24 24 (after mac), it should say 26 26, but the method is correct.

When I try to replace it on my device, the error goes from 0x10 (NULL mac) to 0x02 (probably invalid).

How to change MAC address?

Hello guys;

Thanks to this thread, I've fixed the problem.

But the MAC address of the phone fixed with this method shoud be the same one.

So, to change the address to another one, I edited WIFI file, then the error occured again.

What shoud I do to change MAC address to another one?

[Micromax A89 Ninja] DAC324:
Hello all,

although this trick with the modified files works in most cases, it is worth mentioning that this error comes from the SP Flash Tool which damages the NVRAM contents. There is one user at Android-Hilfe.de who knows how to prevent this error but unfortunately, he does not want to tell anyone how to do it.

Kind regards,

---------- Post added at 01:05 AM ---------- Previous post was at 12:58 AM ----------

If there's no /data/nvram folder on your device,

Go to the root folder (/), you will find the /nvdata partition.

And paste the files at /nvdata/APCFG/APRDEB folder.

Good luck!

---------- Post added at 01:07 AM ---------- Previous post was at 01:05 AM ----------

First, make sure your device has root access.

If there's no /data/nvram folder on your device,

Go to the root folder (/), you will find the /nvdata partition.

hi,

i just got a note 3 N900T being used on t-mobile. i currently have the unlimited 4G LTE plan without tethering but have been tethering just fine on my rooted old HTC phone. i've read through a lot of the rooting threads here, but i'm not quite sure if it's possible to root this phone without setting off the knox counter, as it's already on kitkat 4.4.2 NB4. is there a way to downgrade to jellybean and root? how do i get the t-mobile tethering crap off and activate the native tethering capabilities?

i have a note 10.1 tablet but this is my first samsung phone - always used HTC before. sorry if there's already a post about this, there's too many different models and carriers.
[Galaxy Note II Q&A, Help & Troubleshooting] jetfly:
Hello,

Allow me to explain the problem from the very beginning...

a) I just rooted by Note 2 using the CF-Autoroot and Odin method, and then installing

SuperSU from the Play Store. It worked flawlessly!

b) Then I tried to flash MJ5 bootloader using Dr Ketan's method here using Odin:

http://xdaforums.com/showpost.php?p=47379632&postcount=2789

I got the fail message and the phone went into "Firmware upgrade encountered an issue.

Please select recovery mode in Kies & try again" error mode

c) I did a recovery using kies as suggested. Phone came back to normal.

d) After this I tried the Odin and CF-Autoroot method again. Now Odin says Pass!,

but the phone is still unrooted!

e) Then I tried Ketan's Multitool and renamed the knox files to knox.bak and rooted with it.

Didn't work

g) Then again I used the Multi tool and tried to remove the knox files and rooted with it.

This time it worked. After first restart, it says root successful.

But after some time, it again goes back to "phone doesn't have root access"

and becomes unrooted automatically.

And this has happened many times.

What should I do to keep the phone rooted?

What's causing it to become unrooted automatically?

Thanks for your help.
[Galaxy Note II Q&A, Help & Troubleshooting] m.b.jikre:
This might be occured because of JB v4.3 Knox, Update your SuperSu and Scripts after when you'll reboot phone, Oper SuperSu, It'll ask you to disable Knox, disable it.

[Galaxy Note II Q&A, Help & Troubleshooting] jetfly:
Already tried it.

Will flash the file you gave and see if it works.

But my question is I removed the Knox files while rooting with Multitool, right?

Can they still come back after being removed?

Maybe there's some other file that's restoring these deleted knox files back.
[Galaxy Note II Q&A, Help & Troubleshooting] m.b.jikre:
That's just a SuperSU scripts and app update, for v4.3 JB they've provided new security for their devices this will helps alot on 4.3 or 4.4.x for updating SuperSU.

[AT&T HTC One (M8)] rahtrip:
Anyone know how the exchange policy works if you used AT&T next to get this phone? I got my dad this phone on the AT&T next plan since he loved playing with mine so much. His keeps rebooting in a boot loop, and has a dead pixel. Stock, and used only for two days.
[AT&T HTC One (M8)] smknutson:
They will exchange it like any other method of buying the phone. Which, this sounds like a warranty issue so the 14 days shouldn't matter.
[AT&T HTC One (M8)] rahtrip:
I have to go through warranty? Can I just go back to the store where I bought it? Can it be exchanged there? Sorry if that's a dumb question.
[AT&T HTC One (M8)] smknutson:
You could exchange it if he wants a different device, but if exchanging for another m8, they will probably treat it was a warranty issue.
[AT&T HTC One (M8)] Crimson Ghoul:
Mine had a defect on the head phone jack. They replaced it on the 14th day without having to pay any fees. They will only charge you if you switch phones. Even if it is just a color change
[AT&T HTC One (M8)] rahtrip:
Was your M8 purchased through ATT next? and they let u exchange?
[AT&T HTC One (M8)] Crimson Ghoul:
I bought my M8 at the full retail price.
[AT&T HTC One (M8)] graffixnyc:
I exchanged an m8 in a store that I had ordered through their website. The phone was bought through Next and I exchanged it on the 14th day. Whoever said they wouldn't exchange it for another m8 is wrong. If he is within his 14 days they will exchange it for another m8 or even a different device. After that they treat it as a warranty issue.

As a matter of fact, if you are within your 14 days and try to get a warranty exchange they won't allow you. They will tell you you are within your 14 days and should exchange the device.

How do I know this? With my m7 I ordered a 64gb in store.. It was defective.. Stores were not stocking the 64gb, only the 32.. I called to exchange it and they told me since I bought it in a store I had to exchange it in a store.. But no stores had any 64gb.. It was a hellish ordeal.. I had got fed up and tried to get the warranty department to give me a warranty exchange.. They did not allow me to... They said I was still within my 14 days. So if you're within your 14 days they won't even let you get a warranty exchange.
[AT&T HTC One (M8)] smknutson:
I purchased two S5s through Next, and it was the standard $35 restocking fee to exchange to the m8.
[AT&T HTC One (M8)] mr.wizard:
Within the 14 day BRE period, all warranty exchanges can be done in store. You don't have to pay a restocking fee, due to the fact there's something wrong with your dad's phone. You don't even really need to bring the original box, though it's recommended.

They might direct you to the warranty center, but should only do so if they are out of stock or you return/exchange outside of the 14 day window.

Get in there right away just to be sure.
[AT&T HTC One (M8)] graffixnyc:
They will recharge you a restocking fee if you exchange for a different device, not if you exchange for another m8. And again they will NOT process a warranty claim within your 14 days. Try for yourself.. If someone is within their 14 days call the warranty department.. Make up some BS abut the phone being defective and you need a warranty replacement.. They will tell you they can't process one because you are within your 14 days return period. Also I learned if you had ordered it from the website the 14 days begins at the invoice date.. not the delivery date which is pure BS.. It should be from the delivery date.
[AT&T HTC One (M8)] YoungAceAtlanta:
You have 14 days to replace the device for a different device or the same one but different color. If they find nothing wrong with your device, then you'll pay a $35 restocking fee(you might not depending on who you get) you'll also pay $35 to switch devices(M8 to S5 or w/e)

Now if you received a defective device from AT&T they can not decline you a replacement. I've ordered many phones from AT&T and replaced them due to damage within 14 days period. No restocking fee was charged to me.

Now unless they changed the policy since then idk
[AT&T HTC One (M8)] twiggums:
factory defect == restocking fee waived

swapping "just because" == restocking fee.

i swapped out 2 M8s with zero fee, and they were willing to swap more out if i continued to find the same problem (dead pixel). Now im not on NEXT but that shouldn't matter.
[AT&T HTC One (M8)] smknutson:
Next doesn't affect exchanges or warranty returns or anything like that. The only thing different with Next is how you pay for the device itself.
[AT&T HTC One (M8)] Longcat14:
Just go to the store, and get them to exchange it for another M8, they'll do it for free since the problems you have are a factory defect.
