Troubleshooting.

I would like to advise everyone NOT to follow instructions dated December 6, 2011, which describe how to install CyanogenMod on the V9C. That makes wifi/bt/sensors dysfuctional. Since we now have a new ROM, kindly follow the new post.

Also, try to give details about the problems you face, and the steps you tried.

Lately, there is some issue with my new post. In the sense that I am not able to view new comments that are posted. That is why, I have not been able to reply to anyone of you.

I request all to ask your questions via comments, underneath this post, not the original one. Also, kindly leave your e-mail address, as it'll help me to respond quickly.

Someone, in emergency, can write to me at sarthilongani@gmail.com.

PS: The solution for wifi problem is mentioned in the comments of this post. What others suggested is a bit confusing to me also. Look for the comment which I wrote in there regarding wifi. Still, if you have any issues, feel free to ask.

Dear sarathi, i have used your latest instruction set only. Please help me out on vedio calling issue. My mail id is cintu.m@gmail.com
Regards.

Capt. Sarthi Longani said...

as of now, the stock ROM has video calling disabled over cellular 3G network. as in, someone directly calling your number as video won't be able to do so.

I had not looked into or edited anything major in the stock, so will have to look again into the video calling issue.

FYI, yahoo messenger with its video plugin, is able to do video chat comfortably, over 3G data or wifi networks. I am looking for other programs which can do so.

Capt. Sarthi Longani said...

mailed you.

Capt. Sarthi Longani said...

original ROM cannot be rooted. I had to modify it externally.

Capt. Sarthi Longani said...

for others who wanted to know, the nv_4319.txt file, which needs to be edited to fix the wifi issue, can be found under /system/etc folder. it needs to be copied elsewhere (like sdcard), edited, pasted back into /system/etc, and then permissions corrected.

I forget my wi-fi mac . How to retrieve my wi-fi mac ?

Capt. Sarthi Longani said...

I have replied to you, and will be hunting for the further instructions you requested.

Capt. Sarthi Longani said...

you don't need to specifically remember your own wifi mac address. you can use any valid address for that purpose, since it is very very unlikely that two devices with same mac addresses will be near each other, ever.

use this link: http://sqa.fyicenter.com/Online_Test_Tools/Test_MAC_Address_Generator.php

REGHU said...

dear friend

do you know the file names that belongs to the UNLOCK in any custom ROMs. Or where are these file(files related to UNLOCK)in the ROM. Becoz I flashed my V9C with your rom.
But the network doesn't unlocked yet. My tab is rooted with the rom.

Before this, the ROM in my tab was Cyanogen 7.1. It is a rom with unlocked network. And I want know how to find the files belongs to the unlocking from Cyanogen ROM. thinking that, copy and replace these files to your ROM and flash again.
pls pls pls help me.

Capt. Sarthi Longani said...

if you have read my previous flashing posts thoroughly, it is mentioned therein that the unlocking is NOT dependent on any files of any ROM. the SIM lock breaks during flashing, since the NV memory is formatted and rewritten.

are you getting the box to enter SIM unlock code on bootup, while you insert the SIM, or are you simply getting no signals?

I'll advise you to do the flashing once again. if still the case is same, kindly post here again. yours is the first case I am hearing who said that the tab is locked after flashing.

REGHU said...

ok, I will do.

I am planning to root my reliance tab with your software. Having gone through the comments i have a few questions.

Mehul said...

Hi.I plan to unlock my R tab.
My main reason for unlocking tab is very poor net speed from Reliance during the last 4 months.
I understood the procedure for unlocking tab and restoring wifi.
But,can u tell me where i can find steps for BRINGING BACK THE OEM OS after unlocking tab and restoring wifi ?
My tab is still under warranty
Is there a way by which i can prevent the service centre people from knowing that i have unlocked my tab if there are any problems in the warranty period in future ?
I am aware that in normal circumstances warranty will void if i unlock the tab.
But i would really appreciate if u think over and come up with a solution to disguise the service centre people and claim warranty inspite of unlocking the tab.
I know that ur method is full proof, but just wanted an opinion whether there are any problems occurring after unlocking such as problems relating to touchscreen,auto orientation,front,rear camera,Bluetooth.The reason being, while surfing,i have gone thru reviews which mention similar problems.
Lastly,would appreciate if u guide me how to reload OEM OS back after unlocking.

Buddy if you seriously want to do it just go ahead, download the jugaad files and flash. Make sure to follow the steps 100%, if you do, nothing bad will happen. I am enjoying my unlocked, rooted piece!

Capt. Sarthi Longani said...

google talk video, as of now, is not working on this tablet. though it installs properly and works fine with chat, it hangs while processing a video call.

Capt. Sarthi Longani said...

if you have successfully edited the above two files, you wifi should be working. that error is a useless message, you'll have to learn to ignore it.

Capt. Sarthi Longani said...

CWM does not works with stock ROMs.

Capt. Sarthi Longani said...

you are probably mixing up the reviews from two different posts. there is no hardware issue with the new ROM.

also, please note that once unlocked, there is NO method to lock the tab on reliance SIM again. if you are forced to go for warranty, they will eventually find out what you have done with it, if the tab is working till then.

the only solution, which I had tried personally, is to brick the tab using a bad flash to such an extent, that it doesn't even turns on.

Capt. Sarthi Longani said...

to all:

who advised you to follow half the steps from 25/01 post and half from 06/12 post?

my new instruction set clearly mentioned the steps to be followed and file to be used, and it also said that CWM or custon recovery will NOT work with this version, since it is an unmodifie stock ROM.

you DON'T have to do anything other than mentioned in the January 25 post. if someone really needs cyanogen and CWM on the cost of wifi/bt/front cam/sensors, for such people, I have left the original post on the blog.

the procedures ARE NOT SUPPOSED TO BE MIXED UP, PLEASE.

for messaging, install handcent mms/go sms pro from the market.

Anirudh said...

Successfully flashed my tab. Now it is working with other SIMs also. Wi-Fi working, Message - separate application loaded. It is now "44'H,ME" Error. Reliance Sim not registering. MTNL sim registers Is there any solution.

Capt. Sarthi Longani said...

well if it does, then the SIM must be in roaming.. in any case, i dont think it should affect you much.

Capt. I tried this procedure and on doing this the led is ON constantly. Now when i connect the data cable, my PC says Unrecognised USB Device. Kindly let me know what to do. The PID & VID is 0000 instead of the actual ones. Is there any way to modify the original driver files to recognised the USB Device with PID/VID=0000.
