Hello.

Today, I write here to get some help.

After several days research everywhere on the web without find anything or some partial informations… I really need your help.
I have some skills but I’m not really a pro

First, I bought this phone from this wholesaler : http://www.ahappydeal.com/product-142733.html

It seems it is a copy of Samsung Galaxy S4. I knew it.
This smartphone worked perfectly until I make changes of recovery.

I rooted my phone with this tuto : https://droidchina.com/forum/showthread.php?tid=607
It works perfectly.

I tried to flash the base recovery with a custom recovery (here : CWM).
I have failed…

[Root] Recovery Tools – Flasher is the last app I used to flash my recovery.
Playstore link : https://play.google.com/store/apps/details?id=de.mkrtchyan.recoverytools

When I rebooted the phone into recovery mode, the phone booted normally… BUT..
Now :
– I can’t use the recovery mode
– my SIM is no more accessible.
– my IMEI is invalid.

– the baseband version is Unknow

In my researches, I found one interesting thing…
It would seem I have corrupted my EFS directory.

Here are device infos obtained with Mobileuncle Tools

I can use ADB and FASTBOOT commands with Androïd SDK.

I’m really allergic with the toolkits…
Odin, SP Flash Tool don’t work. Why ? I don’t know.

I tried to use EFS Professional to repair Unknow Baseband / No Signal but this soft don’t work with my phone (no Qualcomm processor)

I prefer use adb / fastboot commands or some scripts.

my requests are the followings :

– Anyone could give me Stock ROM and Custom ROM ? (I think I need Recovery, Boot, Cache and System ROM)
– Anyone could give me an original EFS directory zipped and not corrupted for this phone ? (I could try with basic EFS directory).

If you need more informations (screenshots) then you can ask me .

I’m waiting for your replies. Many Thanks.

The only thing I can suggest is that you can install a new ROM (make sure it is the correct one for your device). When you install a CWM, it also has to be compatible with your phone, otherwise, you will have problems.

If you haven’t backed up your ROM before doing such things, only the people who has the same phone can help you unless you find the rom on the internet.

It’s a joke ?

Hello,

here is news :

You can find lot of ROM here : http://www.needrom.com/?s=JDQ39.I9500ZSUAMDF&sa=search&scat=0

This ROM (ALPS S4 GT-I9500 : http://www.needrom.com/mobile/alps-s4-gt-i9500/) works with my smartphone but the screen is inverted. Into build.prop (system/build.prop), the parameter ro.sf.hwrotation is set 180 instead of 0.
I tried to set to 0 but I had an infinite boot…
This ROM (Bonni ROM : http://www.needrom.com/mobile/bonni-rom-gt-i9502-e-gt-i9500/) works with my smartphone but this ROM does not contain any userdata.img. I used the previous userdata.img

To retrieve the recovery, I used this app [ROOT] Recovery Tools – Flasher https://play.google.com/store/apps/details?id=de.mkrtchyan.recoverytools.
I taken the recovery.img in Bonni ROM.

Recovery is BACK !

Now, I’m seeking for some help to rebuild, reformat, retrieve an EFS directory because my IMEI is invalid and my network connection (gsm) is away.

When you use CWM Recovery, please backup your ROM!
