Unlock 3G bands (greyed) on MTK tablet - Android Q&A, Help & Troubleshooting

Not sure, if the post belongs here or elsewhere, but here's the story:
Recently I've got a generic chinese fake specs tab. Jlinksz ZH960. MTK6582 1/16. Bad thing is that UMTS bands in engineering mode are disabled (shown but greyed), and only GSM are available. So the quest is what's the way to enable UMTS bands?

Same, i bought a Chinese phone, OUKITEL but doesn't enable those greyed bands. Hope there's a solution.

[Q] Is the Samsung Galaxy S II penta band 3G 850 900 1700 1900 2100 frequencies

Hi all
Thanks in advance for any help please provide links if possible. So I've finally stopped waiting for Nokia and then Nokia/Microsoft to get their act together and jumped on the android wagon. It seems android has everything I'm looking for (sync to outlook, office document viewing editing, etc not Garmin yet though).
Anyway I've been doing research on the Samsung galaxy s2 and found some discussion on the 3G modem/antenna being penta band. Is this true? If so can I get links, also how do you enable all the bands? Or can you enable those bands that pertain to the firmware and have to keep the other bands on the phone so if you need them you can flash.
Side question I played with a korean S2 and saw that it has NFC on the apps (out of the box). I'm pretty sure this is true but I'm having some doubts as the FAQ and some other forum member claim that no current S2 has this feature.
Thanks
It's quad band 3G. 850/900/1900/2100. It does not do 1700.
From Samsung.com:
Quad band GSM 850/900/1800/1900
Quad band UMTS 850/900/1900/2100

As for NFC, the I9100 does not have it. I'm not sure if any of the other Asian models (different model numbers too) have it or not.
I heard that the modem intel x626 gold is penta band (unconfirmed) that is in the galaxy s2. Also the tmobile version is coming out which has 1700mhz this might lead me to believe that it is penta band in hardware and only needs software.
Only the korean version of the s2 has NFC.
No other version has it as cell phone providers are thinking of releasing it attached to the sim card as soon as the technology has stabilized and is widely available in a number of countries.
here is some information about in this blog.

the sd card sounds like a good idea as a aftermarket part but I thought I saw the SGS2 with NFC on ebay as the I9101. what would happen if I had to add extra memory to the phone?

I emailed Brian Klug that did the review of the SGS2 on Anandtech.

It is one of the most in depth that I have seen but here is what he says about the SGS2 being penta band.
"XG-626 is compatible with more bands, however the limiting factor always is whether the device manufacturer has provided the power amps for those other bands, and in this case there aren't more."

[Q] Modify SHV-E120L NV settings to enable 850

Hi I'm looking at seeing if i can modify the NV settings for the E120L to get 850 and possible LTE working on Telstra.
I have looked at other threads and forums and seen some limited success at doing this on Moto and some phones for Europe. Having looked at the NV dumps from Moto's i see a number of settings for WCDMA 800 and have also reviewed some of the general settings. As the moto i've seen isn't the MSM8660 chipset i am looking to see if i can obtain some NV dumps from MSM8660 phones to base my experiments on.
I note the Galaxy Note is one such phone and it has been released here in Australia.
other SII's from the telstra Network would be OK as at least then i could get a feel for the Qualcomm settings for 850.
Additionally i understand from some of the threads here that the E120k will work on Telstra 1800LTE, this might be a good option for this part.
Can anyone out there help with some NV dumps.
cheers.

Lenovo S660 - can 3G 900MHz be enabled or is it HW?

I bought Lenovo S660 and it was advertised of having 900MHz support, most websites claim it does but there are some stores which only promise 2100MHz.
I can received the phone and noticed that it apparently only supports 2100MHz because 3G disappears when moving further from town central. Phones bought from my country have the support and stay in 3G.
Are there two versions of this phone and one of them is simply missing required hardware for 900MHz or can it be software unlocked? I have seen couple custom roms for this.

Unlock all bands on LG K7 (K330) T-Mobile

Phone : LG K7 (K330) T-Mobile
Chipset : Qualcomm MSM8909 Snapdragon 210 (LTE model)
I tried to follow these guides : http://forum.xda-developers.com/z3-compact/general/guide-unlock-z3c-international-bands-t3091344 & http://forum.xda-developers.com/cro...ad-progress-please-leave-im-updating-t2871269 in order to unlock all 3G & 4G bands because the phone was bought in US and now I'm in Europe.
The initial state was that phone could only operate at 2G networks in Europe.
I tried several combinations on the enabled bands, like all of them enabled, only the European ones, only a few etc etc but nothing worked. The phone could not detect the SIM at all, or at some occasions it was in a loop trying to connect and was showing the "welcome to <carrier>" pop-up without actually managing to connect to the network/cell at all. Even when all bands were enabled, the phone could not operate even at 2G network (that was initially working).
(I have checked after reboots etc that the new NV values are saved as should).
At all these failing states, the process qmuxd was running continuously at 100% cpu (if this info is at any help)
Now, I reverted it back to US bands, and it operates at 2G
My question is: since the chipset (as mentioned at its specs) can operate at these bands, shouldn't it work? Is there something else I should have in mind, that maybe prevents the phone/antenna from operating at European bands?
Thanx in advance
You have to contact the carrier. T-Mobile 1st to see what options are available to you (since it's a US Phone), and then call your current carrier provider if T-Mobile can not resolve this issue. Hope this helps you.
