Depends what you want form a ROM, but personally i would recommend the current CM 7 Nightlies

After, battery calibration which you need to wait a reasonable length of time before completing (7-10 days), you should be able to get at least 24 hours out of a charge

The root solution for NAND devices involves using a bug in the firmware, HTC rightly consider this a security hole and have plugged it with more recent releases hence we can't use the exploit to achieve root. As for the differences in firmware I assume you are talking official FW? if so some odd bug fixes and security fixes

Radio S-OFF, involves using the radio, rather than the bootloader to turn the Security OFF, this give a belt and braces approach to turning the NAND protection off
I can only comment about the battery. I followed the battery conditioning tip and I can get around 12 hours of massive usage from the device. Thats 3g on, gps, internet, sms, downloads, games, auto sync, etc...
It only gets better if you try conserving.
What is NAND?

the nand chip, is used for internal storage. basically, as default portions of the nand chip are write protected, turning your device s-off, removes the write protection....
Battery life can vary a lot with different roms. I use Android Revolution HD. Some people are reporting battery life of 2 days with the latest build. I have not tested my life yet but it has definitely improved over stock.
What are these diffrent Radio? and what are the differences?
hi, Ive been using a Arc in the US for about 1 month now on T-Mobile, though Baseband 56 is bad, it constantly gives me dropped signal and such. so which one would you consider? thanks !
Use 64. It's stable for me... on 36 I have some problems with GPS connections
Agree use -64 with baseband patch. That will save your day.
thanks for the reply, does it help with battery life?
-36 baseband has for most users the best battery life.
i tried 36 yesterday because i have Battery problems ( i am using FXP 104), but the drain is not better than with 56 before, now i want to try 64, but where can i download the ftf? most Filehosters seem to be down
And in Deposit Files i have to wait for hours because i already downloaded the Libs there today..
Thanks!
With 56 baseband I had alot problems with signals. Testing 36 now and it seems very nice this far.
For .fi users, 56 had no problems with Sonera but it seems that Saunalahti/Elisa is having promlems that drived me testing 36 and maybe later 64.
Hey all!
I have some problems on my Galaxy Nexus GSM Phone!
The problem(s) are:
Bad Battery life, uses too much battery.. :S
sometimes WiFi signal jumping from 2 to 4
I have tested many ROMs but still same problem..
I have changed baseband radio many times!
I have changed Kernel 3 times!
trinity or what it is, it's not good for my GSM GN and then I flashed Franco kernel that is OK, CMtuna was OK but I wanna use it when it is more stable..
When I bought Galaxy Nexus then all was fine but I didn't get any updates so I flashed to custom ROM...
(I'm using stock 4.0.4 ROM and I changed XXLA2 to XXKK6)
Anybody can help? I need help quickly! Thanks if you can help!
GSM GN, I bought it from Finland and I live in Finland so which is the best baseband for my GSM GN?
1. Looks like screen eats out all your battery, are you using it at 100% brightness? As for kernels, i'd recommend using stock one. Currently i'm testing Franco M3 and battery seem to drain out a bit faster if compared to stockc IMM76D kernel.
2. If signal never drops actually - just ignore it.
Edit. I just noticed you're using nightly kernel with 512MHz frequency on GPU... Looks like you're messing with stuff you have no clue about. Insane overclocking and good battery life is something from hard to imposible to achieve.

OK, I can't find stock kernel (I haven't found yet), I just tested the newest nightly kernel and whatever what ROM I use, what baseband radio I use and Kernel I use them will not make really much difference, still battery goes empty too fast! :/
I keep WiFi all the time on, I'll newer turn it off when it's available to use WiFi, I never use 3G or 2G..
on ZTE Blade CM7, battery stays 1/2 days in 90% and it's using WiFi all the time..
Brightness is in 100%
Thanks!
I flashed GN-GSM Gybrid 3.0.29 kernel!
It works and anybody know is this good for GSM GN Battery? so I mean does it use so much battery as usually modified kernels uses?
just flashed and performance might be a little bit better, about battery I don't know yet!
And what is your screen on time? With 100% brightness you can use any kernel/ROM you want, nothing will help.
Edit: added stock, insecured IMM76D kernel (made by Revoked). Don't forget to wipe Cache/Dalvik-cache.

with tuna kernel 3.0.24 in 16 minutes battery has used more than 6%...
I don't understand why my Battery drains too fast, I have no Idea how to fix!
any kernel, baseband or other ROM will not help!
and I can't find information about the right baseband radio for europe: Finnish/Estonia (other north countries)...
:/
I have to go soon to store to check out what is the baseband radio what GN uses in Finland!
Thanks really much for helping me!
EDIT: I'll flash this ROM: http://forum.xda-developers.com/showthread.php?t=1625700&highlight=stock
Why would you use so outdated ROM (4.0.1)? I'd suggest you to download and flash latest IMM76I image from Google, it will update bootloader (to PRIMELA03) and baseband (XXLA02) is well. This would wipe your phone, so don't forget to make a backup of your all internal storage.
OR
You could try this - http://forum.xda-developers.com/showthread.php?t=1586807&highlight=imm76d and then manually flash XXLA02 baseband. Doing so would not wipe your phone.
And i'll repeat myself: no ROM/Kernel/Baseband will help you to save battery as much as reducing screen brightness would.
Looks like quite a number of wakelocks could be keeping your phone awake while your screen is off. Download BetterBatteryStats to help identify what they are. I suggest reading through this thread.

I used that and with that I used XXLA2 baseband radio..
:/
It's not good for my GN!
the outdated ROM should get updates so then I can update it to newest version!
also I can try to make AOSP ROM for my GN but I'm noob to make ROMs, I just can port ROMs to Jet!
I don't know did I all right or wrong
http://forum.xda-developers.com/showthread.php?p=25495298#post25495298 with those steps I installed https://developers.google.com/android/nexus/images#takju 4.0.4 (IMM76I)
and then kernel...
But all worked when I flashed them via fastboot by extracting the files from .tgz + .zip
Is that normal the templerun game lags little bit on 4.0.4 IMM761 with stock kernel +and baseband is XXLA2!
Hey guys what kernel you recommend for my Galaxy Nexus GSM?
(not nightly, milestone..)
I'll try other baseband radio soon, first I have to charge battery to full and then to wipe battery data..
EDIT:
I changed wifi.supplicant_scan_interval=15 to wifi.supplicant_scan_interval=150 to save battery + soon I add little bit more tweaks to save battery..
EDIT2:
How I can make flash able .zip file to change build.prop?
can somebody tell me how! ? (I replaced build.prop via Es file explorer)
With Stock 4.0.4 ROM (using stock kernel, XXLA2 baseband Radio) + tweaked build.prop to improve battery life.. IMM76I
I still haven't solve the problem..
in 2 minutes without charging 1% less..
So Please tell me which is the most stable with the best battery life Kernel + What baseband radio is worth to test (Europe, can be America too?)
Please help me to solve the problem then I do not bother here anymore..
Edit: I'm using XXKL1 baseband radio now, maybe battery is better now too!
How I can make Kernel dump on Windows/Linux Ubuntu?

Yeah! Now I use Jame bond kernel and it helped little bit, I have to go somewhere store to check the right baseband version..
13 min without charging and it used 4% battery, so still battery drains too fast!

radio: ex: EN 301 908-1 V4.2.1 (03-2010) Do you know WHAT IS THAT?
I really don't know nothing...
I would suggest going back to the roots. Charge the GNex to 100%, boot into CWM and delete battery stats, use your phone until the battery completely dies. Charge to full 100% and repeat the cycle a couple of times.
The battery should get calibrated by then.
I'm using Android Rev. HD ROM, and while it has its issues, its mostly stock with stock kernel and the best battery life I could imagine. But then again, I keep my screen at Auto Brightness!
Hope that you can solve your problem, 'cause it really is a beast of a phone!
I repeat this third and last time. Do not use 100% screen brighness, otherwise battery will suffer badly. There is no ROM/kernel/baseband/magicians that would ADD extra power into the battery. Some kernels might offer little bit improved battery life, but this improvement is nothing if compared to amount of power that screen eats at max. brightness.

Wrong once again. Your phone wouldn't work at all with incorrect baseband. Good luck searching for aliens under your bed, i'm out.
I have been having this big question, im trying the best battery life on my play (r800a), right now im trying stock .42 with SC v6 and using doomkernel v14 with baseband -36 but i dont feel it really good.
What do you recommend? ROM? Memory manager? Baseband? Settings?
Have you tried using a different govener? Perhaps you need a sleep profile or you need to use one that can put the phone into a deep sleep.
Sent from my R800x using Tapatalk 2
Right now im using smartassv2 and noop. I dont know if it is the best option, perhaps using the baseband -36 has increased battery life a lil bit. I will try one of this days flashing .62 firmware without the supercharger v6.

try jokawild v3 .62, with doomkernel v14, baseband 64, smartassv2 and sio governor. It works the best for me. also try juice defender ultimate, it is amazing, it turns off wifi, 3g, gps when you're out of range etc. It makes my battery last for 3 days!!!

I've seen that jokawild v3 has really poor battery life, may be due to the apps you're using that you are getting good battery life, i also hate the themes of jokawild roms, i will consider those apps that you recommend and i will flash .62 from the r800i

Best baseband/rom/kernel for battery life.
Id like to know who had the best experience with lower basebands so I can update to the newer firmwares and keep those kernels.

Yes, from a fresh installation of this rom it drains battery life because it is by default overclocked. But I managed to get my battery lasts for a long time and my juicedefender score has increased to 2.58% meaning i am near tripling the life of my battery.
i am on baseband 64 android 2.3.4 build 4.0.2.A.69 btw. i use smartassv2 as governor for both screen on and screen off and my min freq is 249mhz and max is stock 1.01ghz. I use noop as my io scheduler. If u always use your phone of course your battery will drain. What saves your battery is when your not using it that is, it is in screen off mode. Here all these battery apps, tweaks, mods will take effect. I can maintain my current battery level for up to many days I wish to as long as i don't use my phone versus the standard and normal battery drain even without using your phone. For example, my current battery level is at full charge 100% and I can maintain this 100% level for more than a day already but without these apps and tweaks normally the battery will discharge by itself. This is the real deep sleep mode others are talking about. Before i only targeted -1% every 4 hours, then I extended it to 8 hours and now a record breaking of two days!! of course I seldom use my phone that much when working and during weekends I use my pc instead.
it is not on the baseband, firmware, etc. but on how you tweak your phone to maximize its potential. Jokawild rom is superfast and stable and i applied my battery techniques to make it a powerful rom for my personal use.
Enlightening. I've never heard of an IO scheduler, just know about the governors for it, Is there a good app you might suggest for such actions?
I'd like to get my phone to that point, it'd be worth the 300 I paid for it. Hah.

No-frills CPU Control works pretty well
VERIZON GALAXY NEXUS RADIOS
Hey guys!!
Im am not sure why no one else has not done this yet but I felt it was about time we had our own dedicated radio thread. Some of you may wonder what a radio is and others may have misconceptions as to what radios do. So let me try to make this clear and simple for all of you. So in a nutshell a radio driver is what allows your phone to communicate with the cell tower, similar to how a printer driver lets the computer and printer communicate with each other. Keep in mind it's a lot more in depth than that but you should now have a basic idea as to what they do.
I would also like to take the time to clear up some common misconceptions as to what radios do and don't do. Now most of this is fact, it is not just an opinion so if you have an open mind you can learn something. However, if you try to argue with me you better come up with a valid argument explaining why you believe what you believe. Different radio firmwares will more than likely NOT give you a stronger signal. Before a phone is released it is excessively tested before being released to the public. During this time the carrier/s test how much power the radio antenna can safely transmit. The way they measure this is through the SAR (Specific absorption rate (SAR) is a measure of the rate at which energy is absorbed by the body when exposed to a radio frequency (RF) electromagnetic field) value and then it is submitted to the FCC. Verizon's fillings are listed as below, in order for these to be raised above this the phone would have to be resubmitted to the FCC.
SAR: Head: .63 W/kg ; Body .88 W/kg , Product Specific Use: 1.01 W/kg, Simultaneous Transmission: 1.39 W/kg - (max allowed by the FCC is 1.6 W/kg)
Click to expand...
Click to collapse
What they will do is control when the phone will switch from 4g to 3g to 2g. This will cause some of you to be able to hold on to a 4g or 3g signal in some place that you didn't used to have it.
Radio drivers can also change the way the phone displays a certain signal strength by changing the way the signal to noise ratio is sent to the android telephony file in the platform_frameworks_base ... EXAMPLE -89dBm 43asu used to give you 2 bars of service. If they want to service providers can manipulate this to where the phone now shows 4 bars of service. Apple has done this in the past and Verizon admittedly did this with the 4.0.4 OTA.
Default values of SNR will display like this...
The LTE signal strength level is the smaller one
between lte rsrp level and lte snr level if both
rsrp and snr are valid.
The lte snr mapping are
Four bars: SNR >= 45
Three bars: 10 <= SNR < 45
Two bars: -30 <= SNR < 10
One bars: SNR < -30
No bars: No Service

One final misconception I would like to clear up is that a radio update, assuming everything I stated prior remains true, should not make your phone's download speed faster. There are numerous variables that will cause the speed of your network to fluctuate. If you flash a radio and notice an increase in speed, whether it be small or large, you are only experiencing a placebo effect. The only file in android associated with download speeds is the build.prop file. With the exception of user traffic what I quoted below will be the biggest cause in difference of network speeds.
Reference signal received power (RSRP), is defined as the linear average over the power contributions in Watts of the resource elements that carry cell-specific reference signals within the considered measurement frequency bandwidth. Used to measure the signal of your LTE (GSM/4g) connection. In short, it's what's used to determine the best cell tower your LTE device can connect to at the given time. Anything below say -80db is considered pretty good and you're pretty close to a tower. -80db to -90db is average what you should expect most of the time. -90db or above and you're probably in an "extended network" area for LTE and getting close to a likely handoff. -105db and above you would be likely to see a handoff to 3G if your signal does not get better.
Throughput for your connection measured with LTE is estimated to decline between 30-50% if your signal goes from -75db to -90db for RSRP. Above -95db and your throughput dramatically drops. At around -108db and worse, your throughput for download drops to nearly 3G rates or worse. Note that this doesn't exactly represent how strong your signal is, just the potential of how efficiently it will send that data.
"But why can I have a super awesome RSRP signal and still my download/upload speeds are not that good (or why is it still sometimes good when RSRP is low)?"
Because it's only measuring the efficiency between you and the tower, not the rest of the network or the end source (the website). There are many network hops along the way to the destination and some may also handle connections inefficiently. The more hops, the slower the connection generally is.
However, it does also represent the greater likelihood that your connection will drop more packets of data that need to be retransmitted and thus not only slowing your connection but also causing it to have to work harder and draining more battery when it's actively downloading/uploading. That's why having it hand off is for the best than fighting it to stay on LTE. This is most likely why people always complained about the Thunderbolt having such poor battery life as no one ever saw what their RSRP was on it, only their RSSI like all other Gingerbread devices.

Now that all of that is cleared up here are your downloads :highfive:
INSTRUCTIONS:
All of these files are flashable through a custom recovery. If you would rather use fastboot just unzip the file a move the radios to your fastboot folder,
1. Download
2. Its is VERY important that you check and match the md5 sum before flashing.
3. Wipe cache and dalvik cache (optional)
4. Flash
5. Reboot
AS ALWAYS FLASH AT YOUR OWN RISK. IF SOMETHING GOES WRONG ONLY YOU ARE TO BLAME
FAQ:
1. Nandoids do not back up your radio and no you don't need to back up a radio.
2. There is no need to wipe yet I suggest wiping your cache and dalvik cache anytime you flash anything.
3. Yes you can go back radio versions if you don't like the one you are on. Just download and flash the desired radio.

Thank you for the information you provided - One question that I had that I didnt seem to notice an answer for.
When a carrier updates the Radio's firmware what are they actually changing / adding / removing that we would need an update. If its just the values to show us bars why so many radio updates.... if it has no effect on speed or signal what is happening when they update radio's.
please disregard

Lol I can see why you might say that off of what I said. I was only addressing some misinformation I have seen around. With anything computer oriented, code is constantly being updated and changed. Just like android operates better after an update so should a driver. The most recent update fixed most peoples connectivity issues with data drops. It also speed up 3g to 4g handoffs.

The thing is, the radio firmware is closed source, so unless someone works for Samsung, no one knows what changes they've made.
And while mark is correct that no firmware can change any hardware limitations (eg, max power output, antenna limitations, etc.), who knows what software limits (below maximum) are coded into that firmware, and how those are changed with each revision? I certainly don't know, and unless someone comes up with the sauce, I doubt they would know either. So while a new radio image may not do anything for performance, it may also do something and not just a placebo. No source, no real proof - - there are just too many other factors that affect signal strength and data ping/throughput.

So a new radio is really just an updated driver for the hardware radio?

Not really. The radio firmware that you are flashing is just that: firmware for the modem chip. It is not the "driver" that interfaces between Android and the modem.

While he is right as well, it is closed source and we don't know for sure. However, from a technical stand point to see any real improvement in signal strength you would have to increase output a significant amount. Therefore, if there is an increase chances are in won't be noticeable by the end user

Mark, thanks for doing this! Following this one.
Ok thinking I understand more but had another question/thought
With so many variables leading to our "download" speeds - What would you suggest would be the best way to compare different Radio Firmware.
1) Signal Strength - Mine shows -106 dBm 34 asu ( with the leaked VZ new radio firmware )
2) Download Speed - This has too many variables I think to use this but to each their own.
3) Co Worker had this thought - Drop your phone down to 3G and use the dBm from that . . not sure about this one.

What I would do (if possible) is get two devices, flash them both with the same stock ROM, but different radios. Then make sure that they are both connected to the same cell tower, and run a speed test at the same time.
is it safe to flash the jellybean radios if you're still on a 4.0.4 rom?
