Dear all
I just get a A7 from a Asian friend.. byt it doesn support the Band 4 of LTE in my country.
Is any way to enable the band 4.
I read in internet that the service mode is a way to enable this. with *#0011# ( that in fact goes to a service mode screen ) but different with the tutorials.. the phone shows
[1] STACK 1
[2] STACK 2
Intead the signal information.....
So i try with <BACK> <Q0000> and <BACK> Q <BACK> 0000 in this menu
also i try inside [2] and [1].. nothing seem to work and go to the "Service options!"
Does anyone know how to acces this menu in A7 2016.. or if there any other way to enable the missing LTE Bands?
Regards,
Are you having a dual-sim phone ?

I need to enable the BAND 4 in an A710 FD phone..
you have to be root. I have the same problem some time ago I tried this method, but it did not work.
if you try too, could share it if it works? http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059

i work a lot in this in my phone.. i finally get how to enter Service mode in A7(2016)
first i go root in the phone .. second part i install phone Info that has the option enter Service Mode in root mode.
But seems that the Network I need to unlock is disable in the NV of the phone, so i need to modify .. i went to the post and try to follow th options.
the problem i found is that the A7 ( 2016 ) is unable to be detected in diagnotic mode
I setup USB options *#0808# to any DM opiton ( Diagnotic mode ) and is supposed to be recognized as USB Diagnostic USB .., but it didin;t work with Normal Samsung USB Drivers.. 1.5.60 do you have any clue on what happening?

Hi,
I would like to have some informations about the Google Nexus 10 Bootloader (and more generally all google device bootloader). Is it possible to reverse-engineering and modify some opcode, or it's signed by the hardware device like the samsung device (I9100 bootloader & co) ? OR is it a way to put my own bootloader based on Das U-Boot on the device ?
The goal is to turn on some CPU mode (hypervisor) to run the kernel in a special mode for virtualization purpose.
Is it sbl.bin who setup CPU mode for the kernel ?
Is bootloader wrapper or 'trampoline like' (which is called by the real bootloader, and will call the kernel with some additional cpu options) is a viable solution ? [1][2]
The cpu load the kernel in a non-secure SVC mode or secure SVC mode ?

Thanks!

Any help on bootloader modification? I have a phone with bricked eMMC and I need to modify bootloader to load boot.img (kernel+ramdisk) from external sd card instead of eMMC if it's possible.
https://forum.xda-developers.com/android/help/how-to-boot-sd-card-qmobile-z8-bricked-t3712171
i have a rooted nexus 6p (h1512) (the international version) with a custom rom (pure nexus rom) and custom recovery...after rooting the device i foolishly tinkered around the hidden secret codes on my device..i downloaded an app called shortcut master (lite)....and searched for some hidden codes...i selected a code 3282 from the options....went into dataSettings, then into lte // edit///(i knew the msl code 000000) and tried to enable band 26...the reason i did that was because i was using an lte sim card and was not getting proper speeds...so i figured enabling a band may make a difference...besides i thought..i could always revert it back...as soon as i enabled band 26....the phone restarted and now i cant get the lte network (no bars)...i went back to the hidden menu to revert the settings but the settings there were exactly similar as before( band 26 was still disabled) ...i cant see any changes that my fooling around had done..and even though i cant get any bars with lte sim....the apn settings associated with the sim are still there..
and i also inserted other 3g sim cards in the phone ...they work perfectly okay...so i think it has something to do with lte bands....i have also flashed the stock factory image from google after this problem after wiping everything, but that didnt solve the problem....i then reflashed the radio too....but it didnt help...so then i went back to my custom rom
is there any way that i can reset the changes i may have made?
any help will be greatly appreciated..
these are the current lte settings on my phone( there is no difference compared to when lte sim was working)

is there any way to reset lte settings?
i think my messing around with these hidden codes has changed some underlying deep seated huawei modem firmware settings...
i just want to know if any of you guys know how to fix this problem? any help will be greatly appreciated.
Edit : All non lte sim cards work just fine..and yes, i inserted that lte sim in other phones and it works just fine, so the sim has no poblem..
EDIT 2: SOLVED...after much searching for solution, bet all my cards on efs partition restoration, was successfull...anyone having similar problems , pm me if u wanna know the commands for nexus 6p to erase efs and its restoration.
CHEERS!!!
Having the same issues on my wife's phone hopefully someone finds a fix.
Had the same issue, download netmonster from market and go into phone info, then turn off cellular radio then turn it back on. Worked for me

Hi,
I've hard bricked my Pro 5. No recovery access, no boot to rom, locked bootloader. After many search i see this : https://forum.xda-developers.com/meizu-pro-5/how-to/meizu-customer-service-flash-tools-save-t3447678, but this is bull-****.
I test many manipulations to get something on my phone other than "Bootloader, Locked".
So i dicovered this : Press and holp Vol + and Vol - and press one time power button. We get this :

Hey there. Got the same problem. Tried everything. Nothing happens. Have you got your problem solved yet?
The same problem

Only way to solve this is taking the phone to technical service. Done it myself. Be careful tought, they will try to make you change the entire mother board (280€), but if you insist they will "find a way" to install the correct software in your phone and leave it as if it was new
it is possible to recovery via dongle ... but sn and imei can be lost
Try this thread.

Try this thread; it worked perfectly for me.
Hi
Ive been trying for the last 2 days to bypass the FRP on the J5.
Ive included some screenshots so that you can see whats going on
I purchased the phone really cheap and i dont know if the phone is locked or unlocked.
it did have a EE sim but i got it without a sim as i was going to put my PAYG sim in it.
it has no sim in it at the moment
Ive done a full factory reset and ive tryed all the easy video options (pressing home 3 times, or using the keyboard settings)
but it doesnt work.
Ive then tryed Imyfone lockwiper but i keeps coming up with failed to find data package
I cant get the exact Device PDA and have tryed the nearest matching ones FXXU5 but none work.
any advice on what to try next easy or hard.
.

Have you got ADB enabled on your phone? I think if you have it enabled on your phone and installed on a computer then you can remove the FRP via command line.
Hi thanks for the response
I spent the past 2 days reading about ADB and USB Debugging before posting as am new to android phone as my last phone has been this
.
.
I downloaded ADB from XDA and opened command prompt to run it, then i run the J5 in download mode, but nothing appears on the computer.
.
.
.
.
if i run the J5 in normal mode (again i cant get into the J5 due to FRP) I can get the J5 icon on the computer but cant access anything else
.
.
.
.
Is there something im doing wrong.
thanks again.
Looking on YouTube there are some videos that show how to remove FRP by flashing a combination file to your phone. You have to find the correct matching combination file which will then allow you to remove the FRP by:
Going into settings
Tap "Build number" 7 times
Go into "Developer options"
Enable "Allow OEM unlocking"
Hope this works for you as I also have a phone that is FRP blocked however I was unable to find a combination file that matches my phone.
