Just got an LG Optimus T. Already rooted, question about Basebands. - Optimus One, P500, V Q&A, Help & Troubleshooting

Hey, I just got an LG Optimus T, don't worry, I have already rooted with Z4root, and flashed recovery with ROM Manager.
My question is this:
I want to install a Jelly Bean ROM but am not sure about the basebands.
If I flash the old baseband fix to update to v20, as recommended in the main Q/A thread, will the stock ROM still function?
And if I do, then would I be able to safely and effectively flash ANY Android 4.0+ P500 ROM?
And why don't any ROMs use the Apps2SD+ script? It seems like a better way of using the sd-ext then Link2SD.
Because this will be my 58 year old Mother's phone, and I would prefer it to be automated so she doesn't need my help as often. lol.
Thanks, and sorry for asking what I'm sure has been asked before.

About basebands:
If you choose to use the old baseband fix, that is temporary, as in you must flash that fix each time you flash a rom. Long story short, this fix replaces three files in the rom zip. Assuming that you have a backup of the stock rom, going back to stock is as easy as restoring that backup.
To answer your question, yes, you can flash any 4.0+ roms provided that you flash the old baseband fix afterwards.
Not much I can say about apps2sd or link2sd. I don't use those scripts.

Cool, Is there a permanent fix for the baseband?
And are you saying the fix changes the ROMs so they will work on the older baseband? And It isn't really changing my baseband at all?

This is the permanent fix:
http://forum.xda-developers.com/showthread.php?t=1149530
And yes, you are correct. The fix just makes the ROMs compatible with your current baseband.
If you don't want to keep flashing the fix every time, use the permanent fix above. The permanent fix actually changes your baseband. With that permanent fix, you can choose to flash either the old baseband or the new baseband.
Since you have the Optimus T, you have the old baseband, so if you want to use the permanent fix, you will need to flash the new baseband. However, if you do decide to go back to stock, you will need to use this program again and flash the old baseband.

Awesome. Thanks!
Is there any benefit to using the new baseband here in the States?

Not that I know of. If I remember correctly, some people claimed that the new baseband gives better signal, but when I gave it a shot, signal wasn't affected at all.
Also, if you have data, it is highly recommended that you keep the old baseband. I had a question similar to yours, and this was the explanation:

Okay, cool. If they do have different radios, (which most T-mobile phone variants do) then to be safe I think I'll just flash the fix after if I flash a ROM for the P500.
Thanks for your help!

[Q] I have rooted LG G2X 2.2 Froyo. How can I upgrage to 2.3 Gingerbread?

Dear Moderators/Members.
I am having LG G2X rooted with Super One Click. How can I upgrade to 2.3 Gingerbread. I tried to manually update from LG’s Mobile Support site but failed. I think the reason is my phone is rooted not original, right?
Thanks. Any help is appreciated!

Being rooted should not affect the updater. What will affect it is if you deleted any system files or changed them since rooting. If you have deleted or changed system files and you want to use the LG Updater you need to return to stock rom first. Or you can use the KDZ method to flash the new GB rom with new baseband. The new baseband improves the phones performance quite a bit.
If you don't care about getting the new baseband you can just flash the stock rooted rom available in the development section. You will have GB but the March baseband.

This also included bloatware, if removed can prevent update..
Could also try:http://forum.xda-developers.com/showthread.php?p=16362191
If this works it will give you updated baseband and put you at stock 2.3.3
Good luck hope this helps..

All bloatware are "system files." So my original answer covered that. Bloat Freezer should be used to disable bloat instead of deleting it. Freezing them doesn't interfere with OTA updates.
Actually the LG updater doesn't care whats going on in system.
When I used the updater, I was running CWM and Eagle'sBlood Froyo, and I was able to update successfully. All I had to do afterwards was re-flash CWM.
I'm pretty sure all the LG updater cares about is that your firmware is v10f.

You sure you didn't use the KDZ method? That would not care. But the LG Updater certainly does check many things before allowing a flash, among them checking md5 checksums for all the files in the previous rom to make sure they are all there and as delivered.
Nope. No KDZ method.
I had CWM, and EBFroyo, which is heavily stripped compared to stock.
The LG updater is very lax.

OTA on rooted phones?

My first question is: is it possible to get the OTA update on a rooted phone?
The 2nd question is there something I can do to get the Software Update check work?
I realise that my first question may answer this one as well, it's only just that all of the other ROM's I've tried did at least seem to contact a checking service and come back with a response that No Updates have been found. This one just keeps waiting for a response and never gets one.
Want to at least try the official OTA ICS update from Vodafone UK if possible, without having to load a stock ROM and locking my phone again.
Thanks

It has always been traditionally said not to apply an OTA on a rooted phone as, historically, it's caused nothing but problems. Whether the same is true now I can't say BUT I would not recommend it personally
do i need to uninstall only SU, or su and clockwork to install ota?
sorry for my bad english
thanks
CWM needs to go as well - you need the stock recovery
Thanks for the advice. I'll have to go stock if CM9 is a long way off. Or try 7.x again, although I'll really miss ICS.

I think as long as you have stock recovery but are S-OFF; it shouldn't be an issue. I looked at some previous posts , albeit from the Evo forum and it seems to be fine. I could be wrong, though.
I keep seeing people post about being rooted and flashing the OTA update. Now someone please, please, please correct me if I am wrong, but when you flash as new ROM, unless you just flash a new system via ADB fastboot commands, you flash a new kernel and all every time you flash a new ROM. So therefor it does not matter if you are rooted cause the rooted kernel will be replaced with a new ROM. For those out there that do not know the kernel is contained in the boot.img of a ROM. Now in a s tock ROM it is. Of always named boot.img but it is still pretty much the same thing with maybe a little more than a custom TOM's would be. So please people stop wording about being rooted, it does not matter. If you are on the correct stock ROM and have the stock recovery you are good to go to flash and run the OTA. It does not matter if you are S-off or S-on either.
It does 100% matter as otherwise the SU app/binary will still be present and potentially cause issue to the 'stock' ROM. Go look at the Desire forums all over the net for examples as to why you shouldn't flash an OTA onto a rooted handset

Ok I well look into this further when I get home from work. I have not looked at the Desire forums yet, bit I will later today. My question is though are the Desire users having to use the stock recovery, or has someone made a flashable .zip file for them of the OTA? If so this could have something to do with the troubles. Like I said I will check into this further this evening. I still say it should not as the kernel is replaced when you flash the OTA update, bit I could very well be wrong.
It's not that you can't do it, you can, it's just not recommended. By all means try it but should it go wrong flashing an RUU is all that would work

I totally understand what you are saying, but flashing stock is not the only way to fix it, it is just the easiest and most user friendly way to fix it. It is pretty much a one click fix, and that is because of the RUU it self. When you flash via a RUU the utility runs a Task 28 on the NAND memory first meaning the NAND is totally wipped, meaning all partitions, before the ROM is flashed. Now you can also use ADB to remove and reflash all partitions,Splash 1(mtdblock0), recovery(mtdblock1), boot(mtdblock2), system(mtdblock3). cache(mtdblock4), userdata(mtdblock5).
Now back to the question about being rooted, I still have not got home yet to get on my computer to look at the desire forums. Now from what I know root is acheived on the kernel level cause that is what root is. It allows for direct communication with the kernel, again correct me if I am wrong. Now I understand that Superuser app binaries would still be present if you flashed just the system. But if you flash a whole new ROM wich is what the OTA update does, then the kernel is replaced with the kerneel in the OTA update, which by is either a completely new kernel or a modified kernel that HTC has made to work with ICS. I have not had time to look into wich one it is, but from my experience of trying to help port the SDK of ICS to the Sensation it is probably a completely new kernel.
Anyway I will have to do some research on the differences between stock recoveries and custom recoveries. Specifically the processes the recoveries run when flashing a ROM from SD card, and just what all is in the OTA update files. Once I get to do this I will be more able to give a hard core answer to this question. Oh and thinks to the EddyOS for helping to get me back into digging around in ROM files and learning more about how Android works.
Edit: I totally forgot to mention JTAG, this is another way that you could fix the problem, all be it sort of a major over kill for the problem, but still a fix.

Need to flash firmware?

Ok, let's say I have Cyanogenmod 9 installed on my TF300T, and then ASUS puts out a .31 firmware. Do I need to flash the firmware, then put CM9 back on to get some part of the update?
For instance, I have an LG Optimus 2X, that phone has a "baseband" that only gets updated when I flash a new stock ROM (when one comes out), it'll never get updated by CM or any other custom ROM.
I am pretty sure that the answer is no. Cell phones have radio software that our tablet does not use or need. Somebody, feel free to correct me if I am wrong.
I agree...dont think so. If it was the case, typically the dev will post instructions to do so.
No you don't. We have no radio's on the tablet so it isn't necessary. The only time I could see it needing to be done is if the bootloader got updated or something.. Highly doubtful. Haha.

Wifi, bluetooth, and GPS all use radios with update-able firmware. So, yes, you may need to flash a stock firmware blob every-so-often for firmware updates.

[Q] Going from CM 7.1.1 to Liquid ICS - Backup to Restore?

I'm thinking about upgrading my Thunderbolt from CM 7.1.1 to one of the Liquid ICS ROMs found on this board. I have a few reservations so I want to do this right. I know enough to be dangerous but I'm far from an expert so any help is appreciated.
First, what I did to get to where I am: I went from a Stock Gingerbread HTC Sense ROM to CM 7.1.1 following this how-to: http://wiki.cyanogenmod.com/wiki/HTC_Thunderbolt:_Full_Update_Guide
To my knowledge, I've never flashed any radios and following that guide worked perfectly. The ROM is a little buggy but not bad. For the most part it works brilliantly and I love it.
However, as I said, I'd like to try Liquid ICS and my understanding is it requires you flash a radio. What I want to do is ensure that I can do a full Nandroid backup now so that in case I'm not a fan, I'm able to restore back.
Presumably that would involve flashing the radio that I'm currently using and then restoring from the Nandroid backup. Is that right?
If so, how do I find the current radio file? My baseband version looks odd to me, but maybe it isn't. It's listed as "1.39.00.0627r,0.01.69.0625r". The comma (seemingly separating two version #s?) is what is throwing me off.
Anyway, I really want to try ICS but I just want a method to get back to my current state if need be. How can I accomplish this?
Any help is greatly appreciated.
Thanks!
Find the 605.19 radio and flash in the bootloader by renaming it PG05IMG.zip. The file has to be on the root of your sd card for the bootloader to detect the radio. To go back to your old radio just download the one you had and flash it in the same manner. Radios aren't as simple to change back to as a Rom but once you know how to flash a radio its easy enough. Just remember to check the md5 sum of your radio after you download it and before you flash it. It will brick your phone if you flash a bad radio. Always rename the radio after you flash it or move it to another directory so that if you need to go into the bootloader it doesn't try to run the update again.

So my assumptions were correct. I need to flash the 605.19 radio to get to Liquid ICS.
How do I know which radio I have now? How do I find it? And the Nandroid restore will work after flashing back to the old radio?

You don't have to use that radio... It's only advised. If you want to flash liquid ics then go for it. If you have some data issues then try flashing the new radio. Make a nand of your current Rom of course in case there is something that you just can't stand. I would say that if the radio you are using now works fine for you then it should still work fine.

Ah gotcha. But still just in case- how do I find the radio file for what I currently have in case I do have to/wish to flash the 605.19 radio?

Yep you can always go back. Just download that radio and flash it the way I posted earlier. I don't know if you will have problems with your current radio but I imagine you're going to have data drops with them and liquid ics. They fixed the ril using the .19 radios so they seem to work better.
Sent from my ADR6400L using Tapatalk 2
Makes sense. Okay, one last question- looking at the link you posted, it looks like I have two radios (at least it's two separate files on that link). Am I losing my mind?
No. They can be packaged together or separate. They can even be mixed or matched. It's usually better to use the same two though. If you do go back you will have to flash each one of those radios to get it back the way you are now. That is unless you can find someone that knows how to combine the two in a zip.
Sent from my ADR6400L using Tapatalk 2
So if I want both back- I can flash one zip and then the other and it'll have both?

Yea. Just remember to change the name of the zip before going back to the bootloader so that you don't try flafhing the same one again.

[Q] [CM10 ROM] No GSM, baseband coming up as "unknown"

Hi,
after being a lurker I finally made an account to ask for help with a problem I can't solve.
I flashed my P500 with the latest 7th build of the CM10 by Rashed97 from stock 2.2.2 with V10a badeband.
All wipes done etc. flash went well.
Only problem, the phone didn't detect any SIM cards, detected no GSM.
I went on looking at all the ways to flash baseband and fix it. In the end I failed, tried LGMDP got errors, tried the fix provided by some of the users but the baseband stays "unknown" (not sure if was like that b4 fix, so I recovered to 2.2.2 and gonna do it again).
I'm asking for some advice, just how am I supposed to handle it this time so in the end I get a functioning phone.
Should i update baseband first, then flash ROM?
Cheers, looking forward to your replies.
First link in my signature below. Try flashing that.
If didnt work, unzip it and place it in /system/lib and set permissions right.
Same as other lib's permissions.

I used the fix already, didn't work. Tho i didn't figure out how to get it into /system/lib (where do I find that directory?). You mentioned in an earlier post, that one has to use root explorer, as in an APP?
Or maybe I'm supposed to flash the fix while I'm still on stock 2.2.2?
EDIT: Ugh, I'm tired and my posts are quite bad, but I got some news.
Baseband turns to unknown right after flashing ROM (flashed gapps also). So I'm gonna try that method of yours with putting the fix into /system/lib , I'm off to figure out how it's done....
EDIT2: Copied and overwrote the files from system/lib but where do the META - INF folder go?
Meta-Info folders are for recoveries not for us
No need to extract them.
Sent from my LG-P500 using xda premium
Sadly, even extracting the fix and putting the files manually into system/lib doesn't fix my problem ( I even checked the permissions).
Maybe I should just try updating the baseband first on 2.2.2 and then flash the CM10 ROM?

So I updated my ROM and baseband with G Mobile Support Tool.
Right now I got stock 2.3.3 with V20c on my P500. I guess I'll make a recovery of this and start flashing the CM10 again.
EDIT: Now this is bat**** crazy. After getting stock 2.3.3 had to fight to root it (finally managed with Onec Click Root). Now when I got my superuser I can't even go into recovery. Holding home + vol up + power makes a factory reset instead (superuser stays, other app like rom manager, quickboot and settings get deleted). So wth?
I think I'll try reflashing recovery with rom manager (after i once again dl it).
Victory!​
:laugh:
Finally I managed to get it to work.
After updating to stock 2.3.3 I already had the right baseband, so then I just had to reflash recovery (which fixed the issue of going into recovery mode) and finally reflash the whole CM10 ROM.
Got greeted by phone asking for PIN, GSM works with full bars and now I can sit back and enjoy the smoothness of JB Android.
I'd like to thank all the people who answered my posts, gave me advice and tried to help.
I really, really needed this :victory: because changing to P500 with 4.1.2 is a really great upgrade from my GT540.
That's both for soft and hardware (finally multi-touch, Donkey Kong Adventure on SNESOID, here I come).
Rock on guys! :highfive:

The Lg LU6200 is a much different phone from ours and probably has a much different solution to your problem, I would recommend you ask on the forum for that phone. The nitro HD is a very similar phone, and there is a development subforum for your phone in the nitro hd's forum so there is probably a solution somewhere on there: http://forum.xda-developers.com/forumdisplay.php?f=1445

You can search the forum mentioned in the previous post or this thread as I think it may be more along the lines of the answer you're looking for. Since I don't have one of these devices, all I can do is search and hopefully point you in the right direction.
