Yes I've followed the procedure I made that mistake flashing CM10, this displays error message on WiFi, disconnected mobile data, no gsm/ hspda connection... i have a screenshot but new to this site
Did you do a complete wipe before installing the ROM ? What is the error ? You can upload the screenshot to some public image hosting site and post the link here. As for HSPA/3G, do you have the correct APN settings ?

i49.tinypic.com/ 33ucvh4.jpg the airplane mode wont allow me to alter the APN settings. I'll try Re-Flash the ROM after my phone charges... thanks anyway i feel ive done something wrong
I started by wiping previous rom and everything (full wipe)
Extracted boot.img into my fastboot folder.
Fast booted via Fastboot flash boot boot.img
Went through the viperx installation in recovery
Rebooted took a while to load then all connections failed to connect on the phone
Hspda, Gsm and WiFi

HOPE THIS IS ENOUGH

[Q] Mobile Odin Pro Fail - Help!

I rooted my GT-N7105 using CWM6 and desktop Odin when I got it. I wanted to update to 4.1.2 without losing Root, so I decided to use Mobile Odin Pro with the EverRoot feature turned on.
I downloaded the new ROM to the root of the device (not the external SD card) and set Mobile Odin to install the new ROM and retain Root.
The device rebooted to the Mobile Odin icon, and then nothing... can't reboot, can't seem to recover, every time I try anything, it just reverts to the Mobile Odin icon.
Any Help?
How can I restore my phone?

Hi mate, I would suggest you to use the odin from desktop and flash a stock rom and then try rooting again using odin from desktop with cf-autoroot.
With a little more searching, I discovered I had a broken cache. Installed a fix using desktop odin and am back where I started. When I get home later will try flashing a stock rom.
Do I need to use triangleaway first?
Broken cache was issue with very old recovery by chenglu, (i think that is already removed)
If so then just flash CF auto root package it should solve.
BTW what option you are selecting to flash ROM with Mobile Odin?
My unit is running 4.1.1 rooted with cwm6. I wanted to update to 4.1.2 and retain root. I downloaded the correct new rom for my carrier (Starhub in Singapore) from sammobile and extracted it to the root of my phone, then opened the file using Odin Mobile and told it to flash with EverRoot enabled.
That's where the process died and I was left with the Odin Mobile android logo frozen on my phone.
After unplugging and trying to reboot - it kept goign to the Odin Mobile logo so I rebooted into recovery mode and tried Odin Desktop to flash the Rom - no luck.
Then tried Odin Desktop with the cache fix I found earlier and that reset everything as if I hadn't started this process.
Now I'm unsure how to proceed.
Should I unroot, flash the stock rom then re-root? If so to flash the stock rom (using Desktop Odin, I assume), do I need to reset the counter? Using Triangleaway?
Am new to this phone so am not sure how to proceed. Any help would be appreciated.
First you check you have latest Mobile odin, if it happens with that too, do this
As per OP, you have CWM so your counter will be already 1 or more.
Simply flash new ROM with PC odin.(though it won't raise counter)
Reroot with Cf auto root.(this will raise flash counter)
Install triangle away and reset counter.
before doing this backup your important data, though above mention method won't erase anything, but in any step if you get bootloops, you may need to factory reset and that will erase data.
I've got it figured, I reckon.
I installed the new rom using Odin, then rooted using CF-Auto-Root
All seems well.
Thanks for the replies - I probably should have been a little more patient and worked it out myself!

No wifi & no mobile signal - please help!

Hi all.
Just got my one x 32gb, basically...wifi and mobile signal was all working perfect, so I did what I usually do and flash a custom rom straight away.
Unlocked the bootloader with the all in one tool kit and the token etc and installed recovery.
Installed Viper kernel, the Viper Rom.
Rom installs fine, then i reboot and it goes to the screen where you have to choose 'language'
I select English, then next screen is 'Team Venom Rom Specs and setupwizard' so i click next.
then a message comes up saying 'Warning = Network service is unavailable'...so i press ok.
next screen is scan and install apps, so i do that, works fine.
Then next screen is 'internet connection' where you can choose 'mobile data or wi-fi etc.....i select 'mobile data or wifi' then click 'next'...but instead of it going to the next screen where it asks me to click on what wifi connection i want to connect to and password etc, it just goes straight to 'Transfer My Stuff' then 'Dropbox'
When ive gone through all that, I try to manually setup wifi via settings, but it just keeps saying error.
Can someone help me out please??
I've wiped everything and tried reinstalling Rom twice.:crying:
Any help would be sooooooo appreciated.:good:
cheers

Maybe you missed a step in the toolkit you used. you usually get the sort of problems you are experiencing when you either, forget to flash the boot image, or forget to erase the cache after you flash the boot image. The boot image is in the zip file of the rom, you should have extracted it from the rom zip before you placed the the zip on your sdcard. Or if you used a custom kernel it should be accompanied by modules which you have to install in the same way as the rom, ie flashed from within recovery

If you downloaded a custom kernel it will have been in a zip file. Extract the boot.img from zip and put zip on your one x. Boot your phone to bootloader choose fastboot usb. Type fastboot flash boot boot.img[or name of image you extracted]. Type fastboot erase cache. Boot into recovery and flash modules (zip file you download) after you flash modules erase cache and dalvik cache.
Thanks very much for the info guys, have now flashed the boot image and got it working. Initial problem was me being stupid, I had not made a nandroid backup of my initial rom so had nothing to recover back to. I then had the wrong hboot for the rom, was really worried.
I really appreciate the help.

[Q] Phone stuck in Micromax Logo, lost imei and bluetooth.

Hi,
I was trying to flash STOCK ROM.
After flashing the stock rom, I found that I lost IMEI numbers and bluetooth address.
So, I went back to recovery to flash the rom again, Android Bot with red alert was coming.
So, I used SP tools to flash the ROM again but now with "Format option" including boot loader also.
After that, phone is stuck in Micromax logo and am not able to access anything including recovery.
Pls help. </b>

Use SP tools again to download (flash) complete stock ROM again. This time, use "Firmware Upgrade" option.
To fix IMEI issue, install Android CDC Gadget Drivers and use MAUI Meta 3G tool. Use this tutorial: http://www.youtube.com/watch?feature=player_embedded&v=-CokpIVGPBw
Hi GokulNC,
I tried flashing it but still its the same condition.
When I did a memory test from SP FLASH TOOL, it sayid NAND flash was not detected.

So, if your phone is booting up, it means you can access boot loader menu. Press Volume up+power button and choose fastboot mode. Unlock the boot loader and flash any ROM or Nandroid backup from anyone. Otherwise format all the partitions from ADB and try reflashing the stock ROM using SP Tools

You cannot just say that stock recovery is not working.
To work with stock recovery, you need to hold power button and press volume up bottom top access the options. That's how it works. Moreover, you cannot do much with stock recovery. Its features are limited. In this case, custom recovery helps
Can you tell why misc error comes when we install cmw recovery

Hello,
A friend of mine tried to change from stock ROM to Eragon a few days ago.
He wiped all data and then tried to flash the ROM from Android system recovery but it wont install the ROM.
So now the phone just loads the boot screen when its started but nothing happens after that. I can still get access to Android system recovery.
From what I understand, he should have installed CWM before doing anything really but what's done is done.
Is there a way to save his phone?
Hi,
no worries, it's safe! Just reflash Stock ROM, afterwards CWM and install Eragon.

I have downloaded K05TS-A.A.vA0L.E1.150725.zip (Stock ROM Elephone P8000_20150909_Android)
put that on sd card, then I tried to "apply update from sdcard"
then I get "opening update package..." then "installation aborted"
is there something im doing wrong?
You need to use the sp flash tool, there is a guide somewhere so either try the BBS.elephone forum or Google it you will need to install mtk drivers on your PC/laptop...

Sp flash tool wont start to download.
Is there a certain setting that needs to be on phone, when you just connect it android preloader shows up in drivers quickly and then disappear. But if you hold down Vol - you get "CDC Serial"
But when in fastboot you get android "ADB Interface."
From what I have understood you want to stay in Preloader.
How do I do that?
Have read about sp flash tool, but there seems to be problems with the downloading proces and the mtk drivers.
Any idéas?
Click download first and then connect the phone while it's off. The guide on elephone's site is weirdly explained.

1. Install drivers on your pc
2. download spflashtool
Turn off phone
3. format all + download K05TS-A.A.vA0L.E1.150725.zip
connect phone to pc while off
4. when its done start phone, takes around 5minutes to boot up.
5. download cwm recovery
6. use Spflashtool again and flash cwm.
7. put eragon 2.5 on your SDcard
8. Restart phone in recovery, turn off, powerbutton + vol up.
9. wipe data / factory and cash, and delvik cash.
10. install eragon 2.5
DONE
Thanks for all your suggestions on how to fix it.
I will try them as soon as possible.
To be clear:
You can only install STOCK ROM with SP Flash Tool
You can only install ERAGON ROM via Recovery
To install ERAGON you need to be ROOT'ed and have working CUSTOM Recovery...
Followed Peinnes list of what to do and it worked!
Thanks alot for the help!
Thx very much for this solution that work fine
Just i lose my imei duration and i fix it via the EngineerMode (*#*#3646633#*#*) connectivity - cds information - radio information - phone 1 - AT+ EGMR=1,7,"IMEI" and for phone 2 AT+ EGMR=1,10,"IMEI" (with the space between + and E and a restart at the evry time), you save me
Have a nice day
