If I did the ROM upgrade for my KJAM what would I lose? I know all the data for sure so I've backed those up already, would I lose lifetimer etc as well?
If you're talking about the cumulative talk time that you see in the Device Information page, that information is stored in the Registry and gets wiped out in the event of a hard reset, so a ROM upgrade would also wipe that out.
thanks for the fast reply. that pretty much sums up my question. now that I rethink it was a pretty dumb question. should've thought of it.

Dude, i made a thread about it and it's right below yours.......
http://forum.xda-developers.com/showthread.php?t=477684
oh.. mine is more of upgrade firmware... i am also asking.. if i decide to push ahead with upgrade , will stuff get loss.. presuming no errorss
I see . Well i have tried it today with hard reseting the phone and spb works perfect ! I don't know about backup after firmware upgrade....
My level 1 upgrade restore from Sprite Backup didn't work - the phone wouldn't complete its startup sequence.
A level 2 upgrade restore succeeded in bringing the phone to life, but some of the apps didn't restore, and some others didn't work.
I'm therefore doing a full manual rebuild from scratch.
Still, early impressions of R2A ROM are good. It feels crisper and snappier, but that's purely subjective (and on an 'empty' phone).
Hey everyone,
I know my way around a computer but I'm an android rooting newbie. I have a T-Mobile USA myTouch. Last night I used Flashrec to flash CyanogenMod Recovery 1.4, backed up my phone with nandroid, wiped and installed JACxROM [v1.5r3]. Phone is running great. I had a couple questions:
1. If I boot into the recovery console, wipe the phone, and load my nandroid backup, my phone will be back the way it was before I rooted it right? Able to receive OTA updates and all?
2. I understand what SPL and Radio is, but what i don't understand is when I would ever change these things? And if I change them, does restoring my original nandroid backup undo the change?
3. I'm sure that the answer to this varies greatly, but if I am doing an incremental update (say from my ROM to the next version of JACxROM), do you have to wipe everytime?
Thanks for your time. This is an incredible community here, there is so much to learn and play with.
Please post in the correct section. The Sapphire development section is for the development of ROMs and such.
As for your questions, I happen to know the answers so I'll be nice.
1. Yes. (But I'm not sure why you'd want to.)
2. Radio updates can sometimes give you better radio reception or better battery life. Spl's can change a lot of things, most notibly: they can sometimes reformat the internal partitions and allocate more space to the user and system partitions (more free space for you)
3. It depends heavily on the ROM and the version.

Hi!
This is my first post and I apologize if it would be a bit long but I wanted to be honest and express what I wanted to say.
First of all, I just want to say.. You guys are great!
I have been browsing your forums years ago while I was still using my HTC Desire HD. I wanted to join then I was afraid to brick my phone and didn’t have the liberty of time to research and study how. I just observed as you guys enjoy modding your phones. But this time, I really wanted to start modding and participate in this community that is why I registered. I just bought my new phone and after two weeks of research and contemplating, I decided to get the Nexus 4. With this, I know this is a very good phone to start my modding ventures..
One thing that’s really hard to do is keeping up with all the information that you guys have already discussed or contributed. Honestly, its so hard to back-read pages and pages of different topics or even the same topics! I consider myself a noob coz’ I do not have yet any experience in rooting. I did some modding way back before when I had my MotoRazr flip phone and did some crazy modding to it, but now android is a new world to me in terms of modding.
XDA is such a large forum already and sometimes you’ll really get dizzy back-reading similar topics, trying to find the right guide for me. Im more of interested to know how things work and not just use toolkits. This way I would not just benefit but rather be educated as well.
I really wanted to start modding and in the future, also be able to contribute to this very great community. I am not a guy who has knowledge in scripts and programming but I am an easy learner and have common sense as well. But I’m not that kind of guy who can easily spend to buy a new phone. I really worked hard to be able to buy my new Nexus 4. Since I am just a newbie it is very likely I might make mistakes. I hope you could help me and guide me as I learn from our forum and from you guys. I do not want to end up bricking my phone.
Thank you for all those who would acknowledge my message and help. To all you guys, great job!
I myself coming from Desire HD..I still remember how painful its rooting process was.Nexus 4 isn't like that..From Unlocking to Flashing a Custom Rom..Whole Process is easy to understand & less chance of getting into trouble..
For learning..you can have a look at this thread..

thanks for the reply!
I read here in xda that you just need to turn your bootloader off so that anytime you want to root it or do some mods, you do not have to make factory reset and lose all your data. So I was thinking should I just turn it off first while I am still trying to learn more about rooting, Roms, flashing, etc. before actually doing it? That way I do not have to erase my data during factory reset if I decide to root a little more later in time where I have already made several settings and setups, contacts and messages. Is this right?
But if I were to turn my loader off then eventually I have to do a factory reset. Since this is my first time to mod, root, flash or use custom roms, so I think the first I should learn before anything else is about backup so I could still put it back to original stock in case I needed to. Could you guys guide me how to make a backup or a full backup from stock and unrooted phone? I also read that there are custom recovery/backup. Could I do this or my phone should be rooted first before I could do this which means I would need to factory reset first to turn my loader off and eventually erase my data even before I could make a backup. Are there apps I could use and what particular files should be backed up? Some things I am concerned of losing is the words I have added in the dictionary coz I have to do it all over again. For apps, sms and contacts should I just use apps available at the Play store to back it up or is there a better way to actually backup everything including settings? Pls guide me how should I do this.

First setup adb http://www.redmondpie.com/how-to-set-up-android-adb-and-fastboot-on-windows-tutorial/, and stay away from Toolkits
Flash a custom recovery like CWM or TWRP in fastboot for backing up and restoring the whole rom (system and user apps, so the whole configuration).
Install Titanium Backup or Helium to backup and restore users apps and data.

thanks for the advice! already flashed twrp because I would use PA later on and many said its better to use this recovery. I actually encountered some problems on Bootloop which is my first real challenge in the world of modding. But i managed to solved it with help form xda members as well.
Tonight I will be proceeding with flashing customs rom (PA). im just reading some more threads to learn more and be prepared to solve problems in case something goes wrong.
Hello everyone! Long time reader of these forums and first time posting. Let me begin by expressing my gratitude for all the hard work you guys put into helping the rest of us with our phones.
I am hoping to get some clarification on what to do before I sell my phone. I have a Sprint GS4 unlocked and running Blu Kuban/TWRP. Due to the excessive amount of travel for work, I am making the switch to AT&T and have a buyer for my phone. This buyer, however, is requesting that I keep the phone unlocked and rooted. I made a NAND backup prior to installing the rom.
What are the appropriate steps I should take to ensure my data is completely wiped and that the phone remains rooted and unlocked? I have read up on it somewhat (and think I know what to do) , but I would rather fall on the side of caution and get personal direction. I am trying to avoid having to root and unlock the phone again.
Any feedback is greatly appreciated.
Thanks!

Make sure you have everything backed up, then go into wipe, and do a factory reset, PLUS do a data wipe. That will kill all the pics and music, etc.

I would do this twice then reboot it
Which things should I select to backup in twrp?
Last time when I restored the backup I got stuck in the bootloader.

Everything!
This is the question that pisses me off every time I see it. Not because the OP asked it,,,but because no one ever really gives a good answer. Rather they give what they do. There are many devs out there who spend a crap load of time making TWRP and it would just be nice if they spoke up and ended this debate. Is it system_images, vendor_image, boot, and data? Some say no Vendor_image because that causes problems. Others say backup everything,,,well why backup everything and take up all that space if you dont need to? I backed up everything and got stuck in a bootloop when I restored. I have been doing android since day one and never seen so many answers to one question. Can just one TWRP dev speak up and give us a definitive answer, or do they not know as well?

This X 1,000!
I've made different backups checking off different things to back up and I'm terrified of having to restore something! Let's just say I'm extra careful of any mod I flash in case I fu-- something up! Haven't had to restore a backup yet and will be shaking when I have to. I have read so much about it, but there is no clear answer and much of it is confusing. And maybe it's the blond girl in me but I remain confused about the A and B partitions - something else I need to read up on.
Wish TWRP devs would have an official message on what to back up and restore! :good:
exactly right! Plus I LOVE the people who say well just back up what they do and it was a fluke that it worked for them. I am like you now, I am very careful what mods I use because I know I will have to start over from scratch and redo my phone. For me I just use TWRP for flashing zips now thats all.
