Mystic Os V6 -Known Bugs - Micromax Canvas 4 A210

I am Facing Some Bugs On MYSTIC os V6 Rom
1. Call automatically On Hold
2. Network issue ( Solved By Modem.img )
3. Weak Volume ( Solved by Flashing sound patch )
Let Me Knw What About You ?
Are U Facing Some too ?

How exactly did you fix the network issues?
I tried replacing the modem according to this post http://forum.xda-developers.com/showpost.php?p=63750178&postcount=210 but, despite having messed with firmwares quite a bit, found myself somewhat lost, because the instructions weren't all that clear.
For one, the modem in /system/etc/firmware wasn't called modem.img, but modem_1_3g_n.img and some of the values I was supposed to edit in build.prop didn't exist, like ro.ril.hsxpa. (I had ro.ril.hxpa though)
So... I made backups and renamed the new modem.img to modem_1_3g_n.img and added the values that were missing in my build prop. Hope that was the correct way.
And well... in the end I VERY RARELY find two forbidden 2G networks, but still not my provider's.
Changing the Radio Band in Settings > Mystic Settings > System > Phone Settings > Phone Information between EURO and Automatic also didn't really change anything.
Any ideas what I can try?
Edit: For the record, it's V6 from 10/11/2015
Edit 2: Welp, I feel stupid now. I tried another modem, this one: http://forum.xda-developers.com/showpost.php?p=63108271&postcount=8 and now everything is hunky dory. (I couldn't try different modems at home because hurr durr, no reception and people constantly petitioning against radio towers)

Hi
we will list all the modem files and flashable zips.
and the best ways for getting 3g
give a day for this..

[MOD] Orange Signal Boost [UMA]

First thanks to the guys on the sensation forum who worked this out,I wouldnt have tried otherwise!Big big props to ratykat and brokenwall.
ORANGE USERS ONLY
You have to Edit your build.prop to have this line rild.libpath=/system/lib/librilswitch.so Then flash the zip file through recovery, Turn on your WIFI and open the app wait a minute and Voila
What about Virgin, who now use Orange's network in addition to their own? Would it work for me?
Exactly what I have been looking for.
Originally tired on ARHD 3.6.0 ICS on Sensation XE following the original guide however was unable to amend default.prop thus caused issues with the libs.
Currently VI 3.5.0 now so will test this after a backup and keep you posted.
Has anyone tested this on ICS?
Wont flash succesfully for me.
I tried it out on UK Wildfire S running CM7 on Orange network, the phone ran really slow after installing it even after multiple reboots, and was unable to connect to the Orange network at all when I turned off the WiFi, just 'No Signal'.

Hi,
When you say "You have to Edit your build.prop to have this line", do you mean that you just add that line as a new line to the build.prop, or do you change an existing line?
I'm kinda new at this so please excuse my ignorance!
Thanks,
Mike

No signal boost
Hi
I have rooted my wildfire s and gone through the process of modifying build.prop and flashing the signal boost
zip file. The result is a red house that never goes green. My Blackberry works fine on uma.
I placed a new rild.libpath line in my build.prop file was this correct or should I have modified an existing line?

dead links.. trying to find working set of files to port android

hi all!
i am working for a few days on my kaiser to get a working android on the thing...
i would like to use the nand-option
the problem is that there is not a complete set of files to use..
i cant find a androidinstall.tar + matching kaisimg.nbh on the web..
i dont care what version it is.. just anything... donut eclair froyo..
when ik found some matching files, the links were dead...
i updated the hardspl and radio... unlocked the thing...
so the phone is ready for it!
everything i am trying does not work.. trying for two days now.. i need my life back! ;-)
some combo's are bootloading.. installing with errors (bad sectors), but a working set is not to be found... sometimes theres not enough diskspace..
changing the nbh with atools doesn't do the job... install script doesnt.. nothing does...
does anyone have a working set of files for me? (root of sd and andboot)
i need a kaiser panel1 240-320 .nbh file. but that is easy to change with atools..
hope someone can help with a link or attachment...
kind regards, joep
You mean CyanogenMod 6&7 cannot be download?
---------- Post added at 09:56 PM ---------- Previous post was at 08:58 PM ----------
Yea I receive an not downloading try again but it seems that it is downloading and opening(try both) without any problem.Please try again.Thank You.
Search Google for "androidonhtc"... there should be files listed on SourceForge.
"Bad blocks" can stop installation if there are enough of them, find out how many and report back. It sounds to me like you have some NAND marked as bad. It can be fixed through MTTY, but I don't suggest just anyone try it.
There are a multitude of android installers for the Kaiser, but the only one I can suggest is the "system_froyo" on SourceForge. Actually, if you type "system froyo eu" into google, without the quotes of course, it should be the first thing on the list.

Have you tried redownloading? Sounds like a bad download. Make sure you verify the file integrity via md5sum.
Yes, flashed maybe 2-3 different ROMs nothing helps.
I've lost EFS folder. Trying to find out different methods to restore EFS folder/informations from dev/ partition. :crying:

The only way you'll be able to get those items back is to get the NV folder unlocked and salvaged from another sprint s3. Get one with a cracked screen missing back but USB and touch still working. After that you basically salvage the info from it and junk it after. Its illegal for two phones to have the same info active/receiving signal at the same time. To unlock the NV folder you'll need QPST. ither buy it 3.5 for 100$ or look around for for 2.7.402 or 2.7.384 or 2.7.374
I forgot which one detects the S2 and allows the edits. The open sesame door method works on it as well I believe. I did one not to long ago but my memory isn't fresh on it. Or you can use the android terminal method that is used on the prevail in order to get the files. Google is your friend for the "QPST" and for the "open sesame door method" and for the "android terminal backup NV items on prevail".

[Q] G3 radio band editing - Qualcomm SoC

hi all-
Can anyone tell me if there is a hardware difference in the radios of NA/EUR models of the LG G3 such as the D855/852/850? Is it possible to change radio band support by flashing a different radio or other mods? I recall that this was possible with the Nexus4, to enable LTE support when the stock phone had it disabled. Could you flash a different radio baseband package to enable AWS on a D850/852, or additional LTE bands on a D855? I have a Bell D852 that I'd like to be able to use effectively on Wind, or T-Mobile in the US but obviously it doesn't support all of their frequency bands.
[update 11-18-2014] I've changed the title to reflect that editing G3 radio bands appears to be possible, user JustLiveIt has done so with a D855, but we do not have full details yet. Much more testing with different models besides the D855 is required!
Hi,
I am interested to know the answer to this for the reason you just gave, as well as myself having issues with low signal area performance.
If you find out the answer, please share it.
Cheers,
Maybe a better or more precise question would be; do the G3 models have a baseband radio package that is flashable separate from the existing ROMs? Can someone familiar with the previous LGOG->N4 conversions and the process to turn on the N4 LTE radio define what is necessary in this phone?
Simply put: this sort of thing clearly has been possible before with older LG models like making the Optimus G (E970/973) compatible with Nexus4 ROMs due to having common components. And logistically/economically it's in a manufacturers interest to keep the highest commonality of components for economies of scale in manufacturing. So logically- the various G3 models should use as few different hardware parts as possible, and differences should be defined in software as much as possible.
Has anyone tried this Qualcomm SoC dev mode hack on the D850 or D852? JustLiveIt has done testing on a D855 only so far. This thread seems to indicate that any and all GSM bands could be enabled on any current Qualcomm SoC.
Any D850, D852. D851, F460, etc users who feel lucky.. please give this radio edit a try and let us know!
Does anyone have the specific instruction set for LG phones or the G3 in particular? I have tried sending PMs to the LG users in the Qualcomm unlock thread but still no reply.
D852 sitting idle, awaiting some LG-specific instructions. I'm willing to do some testing and provide feedback, I just need a guide on testing with the G3, everyone else in the Qualcomm thread is either Sony or HTC users it seems. And neither of the users working with LG phones in that thread have responded in a week..
I got a reply back from JustLiveIt on Wednesday, unfortunately he has been offline while moving from the US overseas, so he will try to provide his radio details to-date on the D855 as soon as he is able. :good:

3.Turn on USB Debugging and switch to MTP mode
4. Connect the phone to PC and open terminal
5. Type this

That's weird...No comment...
So what can we do to re-add or load the necessary files on a Lollipop ROM? OR do we need to flash back to a stock Kitkat build? Does anyone who actually knows anything ever read these threads??
---
I've only been looking and asking for help and information for FOUR MONTHS in the G3 forums and the Qualcomm chipset thread and noone has provided any tangible information for the G3 phones, ever. I said right from the start I was willing to use my D852 to test and provide feedback, noone could even be bothered to reply. I asked people who claimed they'd had success with other G3 models, they provided nothing. This is why people hate on XDA- because it's full of useless posers who can't do anything except rehash files written or edited by others and take their credit. LOL ROMz!1one!!wan But ask for something original and useful to edit the hardware? Complete silence. Guess I may as well just sell my 852 and go buy an 851 on eBay, at least it will have what I wanted out of the box, for only $500.

Sorry, this is actually just the LG service menu accessible on any stock ROM LG phone with the standard 3845# code.. It is not really unlocking or enabling anything that wasn't already available from your provider. In fact this is pretty clearly an LG service code testing hook as this works on the stock ROM, but does not work at all on a Lollipop ROM such as Candy5. 3845# doesn't work there either.
Has anyone gotten this to work?
I have a d851 on t-mobile in the us and want to try to enable band 12 for lte
Glad that this treat is revoked again and sorry that there still is no usefully info about some interesting questions, specifically about hardware ( also regardless to ^^^post#15), would like to provide some personal update and experience past couple mounts with mine d851 model that i don't want to give up, since where i am, accordingly to lte i need bands 3 and 20, which d851 officially doesn't have them.
I did try every info that was find on net, was do a every idea that i can thing of (lacky me phone survive after couple serious crashes ), what from i know fore sure in editing android or it was hit and miss, try and error, restrictions of free (read demo) softwares, pagans magic and voodoo zens, etc etc... all i can say that i didn't succeed in enabling 3 and 20 bands and still looking for answers.
Also have a question: is it possible to change some hardware part (radio, modem, soc, whatever) and from d851 to transform in d855/d850/bands 3,20, and supporting it with appropriate software (kernel, baseband, whatever)?
I got it working.
working with qxdm not in a band 12 area dont know if it worked but settings sticking from boot.
You need to set the selinux to permissive then run from a su adb prompt

[Q] No 4G/LTE capability after IMEI repair

My G3 was reported as stolen (presumably by the seller) shortly after I bought it, so the IMEI was blocked on my network. I sent the phone to the US for repair and, after some hassle and a complaint to Paypal, I received it it by return post almost 6 weeks later. Not sure if I can mention the "repair" company here but PM me for details, if you'd like them.
The phone now works on Edge / 3G but will not connect to any Australian 4G network. I've tried flashing the European (4.4.2) tot and Australian 5.0 tot but the situation persists. In slight desperation, I'll try the Hong Kong tot later today but in the meantime, does anyone know of a solution?
Possibly useful info:
There is no EFS backup.
The (new) IMEI is displayed in Phone Information and with the "06" code entered in the phone.
The model number is D855 (not D855K or any other variant)
The phone was rooted and running (I think) ANHD Lollipop when it was sent in for repair.*
Extensive searching has not produced anything that has been of use.
LTE is available in Network Selection and it sticks after reboot, so no need to use 'hidden menu', delete system files, etc...
* Probably the cause. The only instructions given were to send the phone without SIM or external SD card.
Have you tried this: http://forum.xda-developers.com/showpost.php?p=54621213&postcount=26
Or this?

Yes. It's nothing to do with settings, I think. I have LTE in settings, no problem. It just won't connect to any band n the hidden menu (I tried each one). Seems that the Australian LTE bands have been knocked out, somehow.
Just discovered that the phone will not connect to data network if GSM only is selected but GSM/WCDMA will switch between EDGE/3G (H - no H+)
HK .tot file did not resolve the problem.

You are wellcome, this is the way it should be i think. I'm old enough who knows sharing is a must ..
http://www.androidbrick.com/qualcomm-snapdragon-imei-tamiri-ders-4-qualcomm-snapdragon-imei-repair/ , the trick is to "zero" necessary partitions, and put your original imei in an orginal untouched qcn backup of your version. You can see it in the pictures of this article. Your 3 partition that holds this info are 21, 22 and 24.
