noob w/rooted & unlocked d800 stuck on 4.2.2 (JDQ39b) need help flashing custom rom!
hey guys so ive had my lg g2 since Feb 2015, bought it ATT and unlocked and using it on cricket. so i rooted it soon after getting and tried flashing a rom and i cant remember what i did wrong but in between flashing a kernel and rom i briked my phone. i had used goomanager to flash twrp 2,6,3 i believe and then that to flash a rom. needless to say i wanted to go from 4.2 to the newest possible rom with no bloatware and very slim with good battery, undervoltage and overckock etc. after weeks having the lg dead and of using a different phone i spent some time trying to figure it out, and used the LG tool to flash the lg back.
now after doing this my phone was back to 4.2 and worked fine except i havent had data or mms working and the battery life is really bad. phone has been like this for a very long time. been so busy that havent had the luxury to experiment snd risk bricking again as i need to at least make calls and text. but i am SICK od paying for data and not having it. please dont tell me to search threads uve spent months before doing that and did all kinds of flashing to no avail. i need help in step by step to get twrp back working, to get the right kernel, to get the newest android version that is STABLE/long lasting battery and perhaps most importantly to have data back.
thanks in advance guys
current version: 4.2.2
baseband version: m8974a AAAANAZM 1.0.190034

Ok, I know there are a lot of threads on these topic and believe me i have spent a lot of time reading multiple threads and the end result is i am not sure how to proceed , for my particular froyo version so I am posting it here hoping some Kind soul will help/suggest me on installing Cyanogen mod 7.
So here I go.
I have an LG P500 model phone with Anroid Froyo 2.2.1 (Software version V10c-DEC-08-2012, Build number FRG-83, KErnel 2.6.32.9 ). After trying several ways finally I have rooted my phone successfully. after making a clockwork recovery of my custom ROM, I proceeded to install CM7 Stable (for P500) using my 2GB memory card with 200 MB free space, it did not succeed and got stuck with the CM7 android logo.
I cleared up my memory upto 450MB and proceeded again by deleting cache/data and installing CM7 stable. This time it did install but i lost the IMEI number and the phone could not detect any network. I got the same result when i tried CM7 RC-3 . being unable to get a working phone I have reverted back to my custom rom using recovery.
After reading so many threads about these issues, i feel that this is some kind of basband problem as mine version is V10C, Can someone please help me how to install CM7 without loosing my IMEI and netwroks. (a step by step approach would me most appreciated). Thanks in advance.
Yes you need to upgrade your baseband to V20, there are several tutorials (step by step) on how to upgrade baseband on this forum.
Sent from my LG-P500
Thanks for the reply, but do i need to install the new baseband after flashing with CM7 or prior to installingCM7, Please clarify this. as I dont want to get stuck again.
cm7 roms are new bb. u need to upgrade to v20 b4 flashng cm7. u can do it using lg pc suite or kdz updater.
Solved
I followed
tried to install V20 using this http://forum.xda-developers.com/showthread.php?t=1217504 which i found from here
I followed the steps in the thread but nothing noticable changed after doing it.
Thinking it had worked somehow I Flashed it now with CM7 but sadly nothing changed and my phone still did not had any network or IMEI even now.
I followed this http://forum.cyanogenmod.com/topic/44849-My-experience-rooting-and-ROMing-the-p500-on-Android-2.2.2..... and flashed using oldBBfix_signed.zip and whoa I got my network working again in no time.
Thank you guys for your reply and special Thanks to the people who made the threads that i have added above. :good::laugh:
I purchased an Optimus T (P509) in 2012 and had it unlocked to use on a trip I went to europe. I played around with it a lot and messed with custom roms and basebands, and then left it alone for about a year. I'm now downsizing my phone/tech collection in general and looking to update this to use as a daily driver.
Here's the info about my phone:
ClockworkMod recover v5.0.2.0
Baseband: LGP509AT-00-V10l-OPEN-COM-OCT-23-2010
CyanogenMod version: 10-20130108-UNOFFICIAL-p509
Build number: cm_p509-userdebug 4.1.2 JZO54k eng.arjen.20130108.030427 test-keys
My questions are:
What updates to baseband (if any) do I need to do? Would this mess up my unlock?
Do I need to flash a new recovery?
What ROM would be best for my needs as a daily driver? requirements are stable without crashes and everything works, followed by the newest android version.
Really the rom part I can experiment with later, I'm just not sure if I've hosed myself with the baseband 'fixes' that I recall messing with 2 years ago. I have a new sim card on the way that I will use with this.

1 - Actually upgrading baseband on that device would lock you out of some frequencies the radio ( not the FM radio ) uses to communicate with the carriers towers. I also have a Optimus T ( P509 ), tho no longer in service.
2 - Depends if you want KitKat ( 4.4 ). If you do then you'll need CWM 6.0.4.4 or newer. I am currently working on a utility for older CWM versions to be able to install KitKat but until then you'll need what I just mentioned. If not too interested in KitKat then you can leave your recovery as is. I use CWM 5.0.2.7 Touch by @vivekkalady. I've been using her recovery since she introduced it.
3 - You'll have to search and make that decision for yourself as we all have different needs and habits.

That's interesting what you said about the current baseband, I'm not sure if I changed it after I last used it. But I turned off airplane mode and popped in a T-mob sim and it wasn't able to connect to a network, similar results with H2O wireless card (at&t mvno). I'm not sure if my current version of android is messed up or the baseband.
I don't mind upgrading CWM, is there any downside to doing so? Is there a kitkat build out now that works? I may want to use KitKat as I hear it's meant to be more usable on smaller memory systems like the p509.
I don't mind finding one I like eventually, but looking for a recommendation to start off with that should work without too much difficulty.
Thanks for you help so far, I hope if can figure out this cell network problem :-/

Either your APN settings are wrong, which you can manually fix, or you did upgrade/downgrade/change baseband. The P509 is supposed to be an old baseband phone. The P500 and P509 are identical. Only difference is the P500 is a new baseband device. You can flash a P500 ROM. If you don't get any signal, then most likely your on old baseband. There is a patch for that, no biggie. If you do get signal then you're on new baseband and you should continue to use P500 ROMs. If you decide to flash a P509 ROM you won't have any service which will be a baseband issue. There is a new baseband patch around here somewhere too.
You can find a link to the old baseband patch in the LG Optimus One FAQ. Post #8 or #9, I think.

I wasn't certain what my starting point was since I'd done this so long ago (and I thought I applied the old BB fix at some point too...). Anyways, I took a drastic step and installed the stock rom V10s_00.kdz with the kdz installer from LG. It successfully flashed and I don't have a brick on my hands
The problem is now the phone doesn't recognize any sim cards, of which I've tried 3: tmobile micro, h2o micro, and a gophone minisim. The microsims were put in a cut out minisim as an adapter. The gophone is a normal minisim that is uncut, but it's not activated. I never got a locked or bad sim message, just that there is no sim card in place.
Under phone status it shows a signal strength (varies -65 to -75 and 25 asu)
Under APN settings it matches the T-mobile ones
And the baseband via secret menu is amss6038
I'm wondering if the sim module or gsm module are messed up? I kinda want to try out the emergency calling but would rather not get the police involved
I messed up my SIM contacts when I left an adapter in there and pulled it a little too hard out! I removed the compression plate on the back and it works again. I'll have to get a small piece of electronic safe foam to apply pressure to the back of the SIM to keep it in proper position. (http://forum.xda-developers.com/showthread.php?t=2598308)
I'm interested in the kitkat build here: http://forum.xda-developers.com/showthread.php?t=2589303
If I were to want to use that, do I need to flash the baseband fix on top of the other install instructions? Anything special in terms of timing it at a certain point in the install process?
Thanks for your help so far, I forgot how much fun messing with android was :laugh:

Well, we still aren't sure if your device is new or old baseband. With the recovery you already have, flash CM10.1, CM10.2, or CM10.3 ( All JellyBean ). Latest CM10.2 builds can be downloaded here. Easiest way to work around the baseband thing is to figure out which ROMs, P500 or P509, that will give you cell service. Flash a P509 ROM. If no service then you upgraded baseband so you'll need to use P500 ROMs. Flash a P500 ROM and if no service then you're on old baseband and you should use P509 ROMs. Only difference between P500 and P509 ROMs is the P500 ROMs are NEW baseband and the P509 ROMs are OLD baseband.
As of now the only KitKat ROMs being build are for the P500. If you find you are OLD baseband, flash the oldbb fix from the FAQ I mentioned a couple posts back. Oh, and you'll need the newest CWM 6.0.4.4 or newer recovery to flash KitKat.
Hope all this helps...

Well, I'm on the old baseband, the reason I know is I used KDZ to nuke it back to p509 stock! The more I read about kdz after I did it the more scared I got, but I lucked out and everything is fine now
The sim unlock is preserved, and I successfully rooted it with gingersnap. I don't have any sort of recover on it yet, it looks like CWM 6.0.4.4 does not work with older roms, just Kitkat based ones. So I'll do some more homework and figure out if I want to jump right into KK or try JB first.
Thanks for all your help, you gave me a quick jumpstart and brought back a lot of knowledge that was tucked away in the back corner of my brain!

Hey all, need a quick hand with my T-Mo LG G2 d801- 4.4.2 stock rom.
Process so far: towelroot>supersu>autorec>twrp>...
Tried flashing CM11, but after about 20min I figured I did something wrong, lol.
What version of cyanogenmod should I be flashing, 10 or 11? From the description of what AutoRec does to deal with the bootloader, it downgrades to the last vulnerable rom to install/enable custom recovery, correct? If so, does it stay downgraded or is that just to get the custom recovery in place?
Don't want to brick my phone experimenting, so here I am. Thanks in advance!
Also should have waited till after work, as I have no more time tonight to mess with it unfortunately. Back in 8hrs! :silly:
Nevermind, I got it working.

Autorec just flashes an older boot loader, with a stock based KK kernel that's compatible. Once up and running any stock based kernel can be flashed if running a stock ROM. It also supports running any after market ROM, however, if running a jb based ROM one needs to be on a jb modem, and if running KK a compatible modem. These are pretty much the only prerequisites.
Sorry, that was rather rude of me wasn't it? Apologies. Not fair to ask for help if I can't return the favor when I can.
Well, instead of looking around on the CM downloads page to get the most stable release, I just got the most recent snapshot of CM 11. Silly me
Turns out the right file to flash first was, of course, the last stable release for the G2 D801, which was CM 10.2.0 (at least at the time of this writing, as far as I know.) After getting the right file and trying again, I was rocking my first custom ROM. Go me! :good:
I have not yet tried the snapshot again to see if I could upgrade to CM11, as I hit another snag: I can't connect to my carrier anymore. I can see T-Mobile in the list for networks but selecting them does nothing, I get no service. Restoring the stock ROM works just fine, its like nothing happened, but running CM I can't connect. Any suggestions?
Good day to all, ya'll have changed things a bit it appears since my last visit. Okay I don't know what is going on as I have flashed hundreds of ROM's without issue and this morning Im seeming to have all kinds of issues. Sprint Galaxy S4 rooted and Flashed for Straight talk network. I am having some kinds of problems and am not able to flash any custom ROM's. Ive tried flashing GPE 4.4.4 and Super S4 ROM and Im getting a Footers Wrong error, error #7 and Signature not verified error and then it will reboot back to the stock firmware. So being my bright self that I am I toggled the signature deal in Clockworkmod and flashed it again and the phone rebooted and started up in GPE, but I could not get a data signal nor would it allow me to even turn on the wif-fi. and now Ive got it bricked and hooked up to odin. Any suggestions, comments, beatings or there of the likes. lol thanks guys yall are great.
Custom ROM Issues
Okay good day once again....Okay the phone has booted up completely and with GPE 4.4.4 or what I assume is GPE. I have no service to the device what so ever, but it does saying preparing network in the task bar and has been saying that for 20 minutes now, I still can not turn on Wifi. When I go to about device it says the following Software Version - Unknown Hardware Version - nothing Android Version 4.4.2 Baseband Version- unknown Kernal Version 3.4.0-216929 [email protected]#1 Wed Jul 9 09:03:50 2014 Build Number - SuperS4-1.5(which means it isn't GPE it is Super S4 ROM, which is cool especially since one of your guys I think built it) and everything else their looks normal to me. So any feed back on this post please. I have to be at work in a few hours and can not do without a phone ....
Hello...! I have some questions to you.... Do you try to flash a custom rom from recovery right....?
And it says "status 7 error"?
I think the reason for this is that you are trying to flash a rom that does not match with your phone or it's not singed...! For example you are trying to flash a rom for Samsung Galaxy S 4 GT-I9500...
Difficulty installing a custom ROM on samsung galaxy S4. Pls help
Pls am having difficulty installing a custom ROM on my Samsung galaxy S4 GT-i9500 Verizon. I have already installed a custom recovery(clockworkMod 6.0.4.7) and the phone is rooted. But each time i try to boot into recovery mode this is where am stuck. i cant seem to find the custom ROM i want to flash i mean the zip file cant be seen and its already donwloaded in my phone. I have some custom ROMS already in my phone for flashing but i cant seem to see the zip file in recovery mode. I took a screenshot so you can tell me what the problem is. Thanks
So, I'm sure I'm probably doing something incredibly stupid..
I just got my Note 5 today. I've been trying to flash a custom ROM, TEKXodus first and then Dr Ketan's ROM. I managed to get them to boot up (at least Ketans, I've been trying so long today at this point I'm not sure if I ever got TEKXodus to load).
However, after finally getting in, my SIM card isn't being detected, neither is the baseband and IMEI. The phone registers as a N290I instead of N290T.
Did I flash something wrong? Would the wrong version of recovery cause this? Kernels?
This isn't my first time rooting and flashing ROMs, but I can't figure out what I'm doing wrong this time.
Any help would be greatly appreciated.

You need to start from scratch (square one) and odin flash the
official stock Samsung N920T Tmobile Marshmallow 6.0 firmware
before doing anything else.
You can find the N920T Marshmallow 6.0 firmware here:
http://sammobile.com
Good luck,
Have a great day!
The phone came with Marshmallow already installed I believe. Either way I've currently got the stock TMobile installed now and am still having the same problem.

Perhaps your phone came with the wrong version of Marshmallow 6.0 if the phone was not new when you got it.
Either way I bet you still have NOT Odin flashed the full official stock samsung N920T 6.0 Marshmallow firmware
which can be found at http://sammobile.com
If you finally decide to do the above be sure to do a full wipe and factory data reset before you odin flash.
And forget about roms until you get the phone working properly with the stock N920T odin flash firmware.
Will definitely double check and retry that when I get off of work.
And that worked!
Thank you so much, I was working off a different MM build apparently. Probably would never have figured that out by myself.
