No one has it, and I really mean no one. I called AT&T and Huawei as well and they don't have it. We're out of luck.

Please do a full backup of the bootloader! So we all can fix our device..!
The procedure is easy and you just take about 8 minutes..
You have to download this tool (for windows)
http://www.roadkil.net/program.php?ProgramID=12
1- Download the tool "Roadkil's Disk Image"
2- Enter to pink screen (volume up and down, then power on)
3- Connect your phone to the computer through the backside usb port (its more safe)
4- Run the tool
5- Click on the "Store Image" tab.
6- In "Store Image to" click the combobox and choose "Physical Disk #" ("#" is a number)
* If there are more than one "Physical Disk #", then you have to choose the one that is about 3.6gb.. This part is very important.. if you give us a backup from another disk, it will leave our phone unusable.
*To be sure that that Physical Disk you choose is the Huawei u8800-51, You can run the tool again (because it has to refresh) without the phone connected, then check which disks are available. Then, close the tool again, connect the device (in pink screen), run the tool, and check what physical disk was added. But it will be about 3.6gb.
7- In "source file", save the file as "u8800.img" in a folder with more than 4gb of storage available.
*There is no risk for you, as it is just data copying, not writting. The risk is for us if you gave us a wrong file hehe..
*If you compress the "u8800.img" file into a "rar" file, the size will be about 700 mb, then please, upload the file into mediafire or some file hosting service.
Thanks man! It will be very useful to many people!
----
*For the ones who do the restore from the file, they have to do something to get the "u8800.img" to work. I will post here what do they have to do before writing to the disk, so Don't restore until I explain it here, or it wont work! and you may have errors!

im about to do it now and sorry im late i never got a chance to do it.

Its not letting me run the program.

Ok I will post the tutorial later.. But about the 3g.. It is working, but you have to do factory reset after you restore from the linux backup..
Also, you will have the IMEI of the person who did the backup.. I tried to restore mine and I did it, but when I restored it, the 3g stopped working.. But in "about" it showed me my imei.. My IMEI backup was made when I already updated to u8800pro..
Maybe the files that this tool (5iromtoolbox) backup are the key for having 3g in the u8800pro rom.. (also with the libril-qc-1).. I dont know.. we should test it later..
Remember.. keep the original IMEI (not yours) and you will have 3g or H+.. whathever--
Advices:
- Do the full backup in Linux
- Backup IMEI (5iromtoolbox)
- Backup CWM
- Backup APN

How to flash the phone with this image? Please help, i need to restore one u8800-51

Restore IMEI and radiomodule
I`m from Russia, sorry for my english
I have too U8800-51 (Impulse 4g) from USA. I bricked him after flash U8800 firmware. I rebuilt my U8800-51 in service center and flashed "U8800-51_dload Froyo Original" and my firmware was from U8800pro. And also changed my IMEI and stopped working 3G and GPS.
Before bricked I am backup my original IMEI with "ToolBox5iromV1.0.4.2.apk".
Today I restored my IMEI from my backup. With the IMEI restored RADIO module (№ 203022) and again began to work 3G and GPS. I am so happy now.
You can do it too:
1. Do the ROOT with "DooMLoRD_v3_ROOT_zergRush_busybox_su.zip".
2. Install "ToolBox5iromV1.0.4.2.apk".
3. Restored your IMEI or my IMEI (if you want) with original radio module of U8800-51 (Impulse 4G) AT&T.
My IMEI link: narod.ru/disk/45304379001.3238bc381c90a94603de19359eda2e72/IMEI_U8800-51_(Impulse_4g)_ORIGINAL_buckup.zip.html

My Radio version changed from 203023 to 203022.
Working HSDPA, HSUPA. HSPA+ probably not works, but in RF not working HSPA+.
You can to try restore my IMEI, before backup your IMEI and if 3G not workingб you return back IMEI

Skipped, can you do a backup of your IMEI when running froyo. Ill restore it and see if I get 3G

Anyone have a working link???
I really was glad to find this post, only to find that the link that may have originally worked only downloads a virus to your pc.
I really hope someone has a restore image that I could use. I am bricked until I find a working one.

titanium and kitkat : sd card problem

Hi everybody!
I can't use the external sdcard to backup my data with Titanium rooted. There is obviously a bug since it says I can't write on that directory/card. I already checked with scandisk. It was fine.
I heard about a bug in Android Kitkat. A story about wrong / new permissions. I am surprised that today, this problem is not fixed yet. I saw a solution where I have to modify some lines in the permissions.xml but ES Explorer refuses to save the file !! Moreover, people report a bug with the bluetooth ...
http://forum.xda-developers.com/showthread.php?t=2537793
Actually, I only want to flash a THL (Thailand) stock ROM although I am using a XTC stock ROM (Philippines). If I do it, I suppose it will reset my phone since these are different countries and CSC.
Boring. I am stuck now. Can't save my phone. Any ideas please?
Thank you!

If you're rooted , try this path /storage/extsdcard/Titanium Backup, or if you modified permission.xml already search for media_rw (grant permission rwxrwxrwx) then choose /mnt/media_rw/extsdcard/Titanium Backup.

Er,... Thank you but did you actually read my post? it doesn't work for me! I tried everything about that.
Thank you.
Edit : my bad, actually, adding some permissions, Here and there AND REBOOTING solved the problem. However, I'm surprised since the creator of the tuto I posted said we can't reboot or we loose the changes (^o^)

Glad you solved it , yes you need to reboot after you set the permission , except for media_rw , you need to set
the permission again after every reboot (for me).

/dev/block renamed.

For experimental purpose, I renamed /dev/block to /dev/block.bak, but after a restart it just came back to /dev/block, I wonder how that works?

Thanks, but rebuild from where? I'm asking is because the phone shows null baseband and I'm not getting any signal. I use EFS professional to
restore EFS, FSG and some other stuff, sometime it works, but sometime after a restart, I'm getting the same issue again.

[Q] Factory Mode

Hello to all you developers out there.
For quit some while now is recieve a consistent warning pop-up whenever i reboot my phone. It only occourse when i'v installed a TW rom. When i'm running any other rom like a GPE for example, the warning does not appear.
Currently i'm on Goldeneye 49.2. My phone is a GT-I9505 on baseband-version: I9505XXUGNK4
I'm not a developer, but a true flashjunky. I would not now how many times is flashed one of your roms and so i do not now specific when this problem started. I'v spend much time browsing the internet in search of this problem and how to fix it. But my effords where not succesfull. The only thing i might have picked up about it, is that is could be related to a corrupt EFS. I hope some of you out there can give me a headsup about this.
Plus! I want to thank all you devoted developers out there. Your hard work and effords are much apreciated.
I have made a picture of the warning.
Thank you for taking your time reading this and i hope someone knows how to fix this.

Hi There,
Thanks for your quick reply. As soon as i read about the EFS, i also read about the backup of the EFS. But i didn't have on.
I made a backup and tried to restore. But i gues a corruption would also be backuped. I also tried to manualy adjust the EFS. Neither workt. Following that i tried holding down the power button for more then 10 seconds till it rebooted (read that somewere between de lines). I also tried various other roms, kernels and basebands. I full despiration i tried returning to fully stock rom. Nothing worked.
Now it has been about a month and a half i left this issieu. So ik can not be very specific about mij tries to resolve.
Is this in any way helpfull?

that is one of the saddest thing that will happen to your phone. My sister has s2 and s3 and she was a flashaholic with different roms and now both phones have no signal/baseband unknown.. She never back up her efs so she cant fix it. I tried my very best to search for an answer, i saw some but it never solve it anyways. Im using my s4 and i backed up my efs every flash that i do. Try to flash official rom, latest modem and pray that it will fix it.

Hi
Well let me tell you about a few things you can try , with some luck they may be enough if not you may have to take it to a local repair shop with a Z3X box of similar they may be able to rebuilt the EFS folder
Check if the EFS folder is mounted correctly
Install / use Terminal Emulator
mount -r -w -o remount,rw -t ext4 /dev/block/mmcblk0p10
mke2fs /dev/block/mmcblk0p10
mount -r -w -o remount,rw -t ext4 /dev/block/mmcblk0p10 /efs
Reboot
With a root explorer go to EFS/factoryApp/factorymode and open it if it says off change it to on
In case none of the above worked check this great thread about EFS and Factory Mode for further help…..
http://forum.xda-developers.com/showthread.php?t=2392632
If those points do not work and without an working EFS backup you may have to look for professional help ( with a Z3X box or similar )

Thank you very much for your help. I did tried to fix the EFS with the guides in the site you mentioned repeatedly. But none were succesfull. The strings you mention in your post, do not look formiliar and i tried them just now. After the second string i get the following in the Emulator:
" can't format mounted filesystem"
Could this be the issieu? Both de FactoryApp and Keystr are on ' ON ' when i open them in a rootexplorer.
And i'm starting to think this problem will, despite all your help, not be resolved.

@MAX 404 try to go to the nearest cellphone repair shop they have this cable that can fix that issue. Its around 4-5$ depends on your country.

Regarding the string , Are you root at the moment , maybe that is the problem , i have not tried in while but they should work...did you check in the thread i gave you?
regarding your other point , ON is the normal , ON is not factory mode...strange but is like that..

I found a wrong reverence in the string. In your string you refer to mmcblk0p10. Except voor the S4 it's ...0p3. Found that out after you let me check the thread again. Although the factory mode is still on after inserting your three strings.
Second thing i noticed was that with the first two string, i get a repley string and info that i can't understand. With the third string, i get no reply string in the emulator. Do you think this can be part of the problem?
I also included a screenshot from the emulator.
