Hello
I'm having troubles with my new LG Optmus L5 e610. It comes oot with 4.1.2 and the LG mod v20b.
I rooted it with the v20d_root.kdz and now i've installed an unlocked bootloader, CWR, CM10 and Gapps. I have now a problem: the IMEI inside the information menù is empty and every SIM card is not recognized.
What should I do? I tryed going back to the stock the reflashig all, but nothing. By the way the stock ROM works fine.
Investigating around i discovered the same problem over many Samsung devices, with following solutions talking about this EFS folder that needs to be backed up. Googling around i found that LG don't need to back up this folder. Am i wrong?
EDIT:
Googling around i discovered that flashing a rom fro the v20_root may cause this issue, so it is advised to downgrade to the v10. But how i do it without making the kdz flasher give me errors? And which one of the v10 kdz i have to flash?
Hello,
You must install v10 baseband.I'n on mobile now and u can't help you but serch on google for it.
Sent from my P700 with GSIV rom and some tweaks in it
Okay, I was able to get into pink screen by erasing the dload folder, removing the battery, and connecting to my PC via the USB cable. I then copied CWM 5.0.2.7 over and then flashed Stallion-51-ICS onto the phone. I now have a very fast, rooted and customized U8800-51, BUT no mobile service. IMEI and APN info is correct but it won't access the mobile service that our other phones access, SIM is the same one that I use in my current phone.
I know you are supposed to back up the IMEI partition and APN before flashing a custom ROM, but since my phone got broke trying to restore a full backup done with CWM I was caught off guard.
Still looking for any suggestions you all might have.
Seriously???

Not to be negative or anything but I think this is the least responsive forum on this site. I have spent hours searching for possible solutions to various problems I've encountered over the past several months, asked several questions and received little if any help. I was only able to get back from a bricked phone to where I am now by using information found on other websites. Pretty sad if you ask me.
In contrast, whenever I have asked a question on my tablet's forum I've received fast workable solutions/answers to my problems/queries. The threads are informative, well organized and contain answers to any situation I have encountered.
Granted, my current problem with my phone is my own fault for trying to customize it. And I suspect part of the problem is due to the age of this phone thus most of the "experts" have moved on to other ventures. It is also hindered by the lack of information available from Huawei and the service providers.
All of that said, if anybody has any suggestions for how I can repair the ESF partition or whatever is causing this lack of mobile service issue I would be extremely grateful. It isn't the end of the world since i have a new phone (Consumer Cellular) that I am currently using but it would be great to get this one working since it's much faster and more streamlined than my stock Consumer Cellular version.
I have experienced something similar on my regular U8800, and it seemed like there was a baseband & modem partitions conflict. In stock 2.3, there should be some kind of hwefsupdate tool, it may be renamed though. This tool gets run on the first boot after 2.3 and it restarts the phone shortly after. Try to reinstall the stock ROM, see what happens. It can be fixed in strange ways - for example, my original U8800 got a USB failure, so I sent it to the repair. I had 2.3 installed. When I got it back, they tried to write over some old 2.2 firmware, which softbricked the phone. Being clueless, I wrote the 4GB image of some other phone's image on my phone, and got everything working again. Then, when I tried to write back my original IMEI, I got the same issue as you. The only way to get it right was to rewrite the "other phone's imei".
The baseband/modem errors are actually very hard to debug, hence no replies. And since it's a Huawei, these guys have even failed to provide a good update system, as seen from the IMEI getting nulled issues. The mmcblk0p5 stores the OEMInfo of the phone, it contains serial numbers & other information about the phone (like accelerometer position up/down for example). It also has the boot image (the very first splash screen). The data is loaded onto modem processor, which provides an API to let userspace access it.

Thank you very much for your reply. It seems that you have found the answer to my problem. But unfortunately, I don't have a copy of the original stock ROM. My phone is the -51 version and any links I have found to the stock ROM are broken. There is a version I found but it is for Venezuela and I don't think it will work. I am leery to try it and totally brick my phone. My backup is apparently corrupted. I backed up my new working phone with Disk Image and attempted to restore it to the broken phone but all that did was cause it to come up to the ATT logo screen for a few seconds and then shut down. It wouldn't do anymore than that. So I restored the Stallion 3.5 image I made and am back to a great fast tablet with no phone service. I also tried backing up my IMEI on the working phone and restoring it to the broken phone but that had no effect.
It is my understanding that the -Pro version of the ROM will work, but I don't have the stock image of that either. I suspect it work might since I was able to use the -Pro version of GB on it. All of my internet searches have only turned up custom ROMs and other desperate people looking for fixes for similar problems or worse. I agree 100% with your assessment of Huawei's lack of meaningful support. It really is a shame, because these phones aren't half bad when they have been customized and OC'ed a little.
I have just about given up on it and resigned myself to using it as an MP3 player for my car system. I have learned my lesson and am leaving the working phone stock. It is rooted and I have cleaned off all of the bloatware, and set it up so most apps run from my SD card, so it really isn't half bad. At least it works.
Again, thank you for your reply and advice.

@Blefish
hi there, can you please give me the exact steps do to so, because im experience the exact same problem.
I've lost the imei in the upgrade process, and them flashed the 4GB image from a user, and then when i try to update to gingerbread, i can't have 3G signal, only 2G.
in the past, i had made a backup of the imei after flashing that .img file, and i think that after update to gingerbread had restored the imei and the 3g was working nice. But this time i cannot acomplish the same, don't remember very well the exact steps that i've made.
I already tried with the B517 and B518, and can't get it to work...
Can you give me some help please?
Thanks in advance

In my case, I restored the full 4GB from some russian community's provided image (it was named Huawei_U8800_FullFlash.bin), which returned my device to stock 2.2. From there I installed 2.3, and everything still worked. The problem in my case was that I could not restore my own IMEI, it never gave me connection & failed to register to a network. The only solution was to use the "wrong" IMEI that came with the 4GB image.
Huawei has some sort of backup mechanism if they think the "data" is corrupted. I can't tell how it works, but it likes to break things that were working before.

i have exactly the same phone than you, because i installed that backup too. After installed it, the IMEI SV is 36, after installing B518 it says it is 18, but before it was 17, and i had 3g signal, but not now.
My question is, wich SV is your phone reporting?
Thank you
I also have a problem like this, but I think it's a bit more severe. My phone got stuck while charging. Couldn't reboot. Was getting stuck on the aurora loading screen(using DZO 5u20). Than reinstalled whole rom. But now I don't any signal and the phone doesn't even see a SIM card. Showing 'baseband unknown' and the IMEI and IMEI SV are also unknown. Not 0's but just unknown. Is this is a similar problem? And can something be done to fix it.
I had some backups on my sd card, untill the sd-card got fried in the phone a couple of months ago.
Hi there,
I realy need your help on my problems with the G2 32GB D802.
I bought it on ebay and instead of getting it from GB it came from HongKong and I didn't think about it that it does not have a european ROM.
First I wanted to root and flash custom recovery and cloudyG3 rom. After rooting with ioroot and installing the TWRP I stuck in the fastboot mode. First problem I did not make a backup because I never reached TWRP. Download mode only appeared for a second an then disappeared again.
After a lot of searching I found that probably the 802autorec.apk was wrong, since I don't have a european model. So I installed via fastboot a laf.img for a D800. After that the download mode was working again and I installed different roms via flashtool2014. The installation worked again but after rebooting the phone I had a lot of trouble with it. That the reason for trying different roms as I sad befor.
First, the fingertip points at different areas of the screen but not there where you are touching the screen. So you can not reach the buttons or write on the keyboard.
Second, after connection to pc I recognized that my 32GB model had only 10GB internal memory.
Finaly I can not use the phone. For me it seems that I burned my partitions and need your help to get it right again.
Please give me a chance.
Best regards an thanks for helping me.
p.s.: I tried to go to the settings menu in the phone and reached it after a lot of confusing taps on the screen. All the phones informations like IMEI and all the other disappeared. Something realy went wrong with it.
No one an idea how to get back to normal?

I now have the answer from the dealer that my G2 has the Firmware D80220B.
Just try and test it. Good luck.
@Angryyolk
I just ask myself how to enter engeniering mode?
Thanks for your help.
I walked one step forward now.
But there is still no solution for my problem. I found a link to LG "http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=IMEI" to get the information about the version of my stock ROM. Just replace IMEI by your real number and you will get it.
In the meantime I flashed the rom with flashtool but the screen behaviour is still the same.
I later rooted the phone with towleroot and then installed the correct autorek.apk for the D802. That worked properly. I reached TWRP but in fact of the weired screen behaviour I couldnt do something. I tried to fix my IMEI problem with QPST but this tool showed only empty tables on my PC when I connected my G2 with usb.
I tried an update of the screen firmware as posted above. The code that has to be entered on the dialer is 3845#*802# but it wont work for me since I can't enter "settings" the service menu. That's because of the weired behaviour.
Beste regards
I now was able to enter the hidden menu. And I was able to get to the menu point "update touch firmware" but nothing happend.
What is wrong?
touch screen problem
The same problem occurred on my phone. how did you do it. please help.
I installed the software and touch screen freaked out.
It's because its a Refurbished Models..
You have to check your Mother board for exact Model
Sent from My LG G Flex LG-F340K Stock KitKat V20D on LTE Network using XDA Free Mobile app
Hey guys. I know for sure there is another thread about a similar problem but the biggest problem I'm having is figuring out what to do next, or better yet, what did I even mess up?
I made a thread a couple days ago here asking about the LTE option on my phone and how there was none. It's an Intl' phone and therefore I guess doesn't work on Canadian LTE networks.
Before we start, I'm using TWRP 2.7.0.0 . My phone is the UAE version of the D802, which is the D80220C. My current custom rom is Liquidsmooth MS3.2 .
So I found a list of modems and flashed the one for Bell. It was for the D803, but the thread I was looking at said it was cross-compatible so I assumed that meant it's okay for me to flash it on my phone.
Even so, I backed up my EFS partitions just to be 100% sure. I even used the .zip file that automatically backs up the current modem files. So I thought there was definitely a way out if it didn't work.
I will give you the full story of what was done and maybe I can get some guidance on maybe something I did wrong.
1) I flashed the D803 Bell modem.
2) Reboot to system, LS3.2 hangs on start up. Tried a hard restart to see if it wasn't a fluke. Nothing. Still hanging.
3) Figured the EFS files were toast, so I ran the restore .zip for my EFS. Reboot, and still hanging.
4) Said WTF? and restored my first stable rooted stock rom. It booted into the rom fine, but when it got to the lock screen I saw the "Service Disabled" and the phone quickly crashed.
5) Didn't even attempt to restart on that rom. So I tried a couple terminal commands to copy the modems1.img and modemst2.img files to corresponding partitions. Copied both just fine, but no change. Still screwing up.
So, this is where I am so far. I am in the process of downloading the D80220C UAE .kdz file so I can try to flash that one first. If that doesn't work, I'm really at a loss.
When I read into this some more, all I see is people who have totally wiped their EFS files and having to spend a whole bunch of time using a bunch of different programs to get in an recover the IMEI number.
What do you guys think?
Some good news right off the bat. I found a KK baseband for D802 and flashed it. So now I was able to restore my LS3.2 rom and boot into it fine. I see my IMEI and MAC address and can get WiFi at last!
Mods, you can delete this thread if you wish.
I was trying to root my at&t s6 edge+ using Odin. As soon as the process completed, my phone froze on Samsung screen. Then I tried wiping cache and data but nothing worked. I downloaded few stock ROM for Odin but flashing keeps on failing. I read in some thread that new Samsung devices do not support downgrading. I went and checked my current build number and found that to be G928AUCS4CPK1. However, the firmware I was trying to flash were older version.
Has anyone experienced similar issue before? The main problem here is I cannot find the exact build number anywhere. I spent a lot of time searching and finally decided to post here.
Your valuable suggestions will be greatly appreciated.
Thanks.
hey man, you flashed an older version of the firmware? even if it wasnt bricked, your phone is essentially useless now. the efs is gone, meaning you cant make phonecalls or connect to wifi at all. sorry; your phone is bricked. perm.
download mode dosen`t work ?if so the only thing you can try is to use samsung kies to restore your phone but don`t know if that works
I done something similar to my standard S6 Edge the only difference was i was able to start it up ok and i thought everything was ok until i realised i had no reception. I so happened to notice my imei number was gone. I had no back ups of the partition that saved this info so i totally bricked my phone.
I did however find a website that would be able to do a work around ( for a fee of course) for it however it does question your morals as its essentially illegal in alot of countries. I dont want to post anything on here so if you want any info send me a PM.
Exact same thing happened to me... went to AT&T repair center but they didn't have the 'K1' firmware..
anyhow managed to find the latest firmware (gsm-firmware.com)... cost me $4, but the phone is up and running... I only flashed the AP file.. also used Odin 3.12.5..
