Hello everyone,
I'm new to the Eris. I've had it for a few months, but this is the first "in-depth" thing I've done with it.
I've decided to take the plunge and root the phone. I'm going to use the on-screen method.
My question is this: What do I need to do to prepare? I've got all my apps backed up to the SD card, and the phone is charging right now.
Any suggestions as to what ROM to use? Or what I need to get the Froyo update, etc?
I'm new, so I'm browsing and learning, but any information you guys have would be great. Thanks in advance.
If you want a Froyo rom, that is what you'll need to download. There are about a half dozen in the development section and all mention "Froyo" in the title. Read the entire thread and it's not a bad idea to read some comments. If the developer says you need the google apps aka gapps zip, get it too. Put both files (or only one if gapps isn't needed) on the root (not in any folders) of your sd. Once you're rooted you should enter recovery by powering off, then boot holding power and vol up (rooting instructions may take you there anyway). Youll see options to reboot, ms toggle, backup/restore, etc. Go to back up/restore and create a nandroid by following the prompts. Press vol down until you return to the home screen, then go to wipe. Wipe data/factory reset and wipe dalvik cache. Vol down back to the main screen and flash the new rom and gapps (if needed). ENJOY. Note: Read all instructions thoroughly before rooting. If any instructions i've listed are different then those listed in the official instructions, follow them first. Once you're rooted and begin changing roms frequently you need to always make a nandroid of the current rom your own (in case you dont like the new one or have problems flashing it), wipe data and dalvik (ext partition too if your sd card is partitioned and you're using a rom which allows apps2sd via a partitioned sd card - froyo currently does not), and backup your apps/settings via the app of your choice before flashing. If your upgrading your current rom you usually wont have to do a wipe (the developer will indicate it in the instructions).
It's a good idea to back up your apps before flashing new roms. Titanium is my favorite app but its for root only. Search the market. You can probably find an app to use before you root.

Wow, thanks for getting back to me with such detail. Very, very much appreciated. It turns out however, that I won't be able to do this.
I checked out http://forum.xda-developers.com/showthread.php?t=742228
I found that I had release keys under my build number, which indicates is the 2.1 leak - which really sucks, because I got the update OTA... why would they send out a leaked platform? That sucks
Ah well, thanks very much for your help. I'm going to take a look at my brothers phone, and see if we can root that. Thanks
You CAN root ANY eris now. Do a little more research.

Greetings.
I just bought my Thunderbolt the other day and so far I'm loving it more each day. I successfully rooted it and got ROM Manager on it.
I'm confused as to what exactly a ROM is and how to get it working on my phone. I've been reading about a few ROMs that de-bloat the phone and those are the ones that I'm looking to get onto my phone, but I'm rather confused as to how to install them. I've downloaded the Des BAMF one and put it on my phone's SD card and renamed it to "update.zip" and chose the option "Install ROM from SD Card." It then reboots into a different looking theme/skin that appears to be the default. I'm not sure if I did something wrong or not.
Could someone fill me in on how exactly to install a custom ROM on the Thunderbolt?
Any help is appreciated.
Hey.
I am in the exact same boat as you. Just got my tbolt and unlocked it.. And for the longest time.. 5 hours i had no idea how to install the roms.
So from what I did.
I backed up my user app on Titanium back up.
I downloaded the zip file.. and placed it in my SD CARD. Don't put it in any folder. or you could you just have to find it, without changing the name.
So then with Rom Manager, you should backup current ROM
Then you should reboot into Recovery.
First we will wipe the data/factory reset.
wipe the cache partition.
Apply the new rom. To do this select the install zip from sdcard.
The next option would be to select chose zip from sd card.
Then you will select your rom from the sd card.
Once you have selected the rom you will get to the conformation page.
I have a link that can show you step by step.. but i am not over my 10 post to post link outside the site
there is no need to rename to update.zip. if you are properly rooted with s-off all you need to do is choose choose "install rom from sd card" in rom manager. Find the rim you want to install (name doesn't matter) and click it. It will then prompt you with two checkboxes.
1. Will be to make a back up
2. Will be to wipe data and cache.
MAKE A BACKUP. As for wiping data and cache that erases everything from your phone (not things on the sd card) it is recommended to do that because sometimes the phone gets weird and force closes if you don't, but sometimes it works fine.
After clicking ok, it will boot into recovery, go through back up and installing and reboot. First reboot may take awhile but after thar you have your new rom.
Let me know if that answered your question. If it didn't, clarify for me so I can better assist you.

greg i have a question. when you wipe data and cache.
your sdcard is safe right?. or does the sdcard get wiped as well

sdcard will not get wiped.
another thing, if your just flashing a new kernel, or updating a rom, like from bamf 1.2 to 1.3, usually a full wipe is not necessary.
But if your switching roms like from BAMF to CM7 always wipe.
just make sure you read the threads and backup before you change anything.
The easiest and simple method of putting a rom on you phone is thru clockwork. You can access the xda site thru an app on the market, just search for xda. Download the app, open the app and sign in. Find the t-bolt forum and download the desired rom using your phone. Once the rom is downloaded, boot into recovery, select "wipe data/factory reset" , select "wipe cache partition", then select "advanced", select "wipe dalvik cache". I usually do this process twice just to make sure. The select "install zip from sd card", find the folder where you downloaded the rom select that then select the file/rom. Install it.
Thanks alot appreciate the feed back and the community

Thank you for all the replies everybody. Clarified a lot of things for me.
I forgot to ask something in my original post; what exactly is a kernel and how would I come about installing it on my TB?
I've been reading a lot about them and I am still clueless as to what a kernel does.

The kernel controls the power and sped of the phone. You can install it the same way I explained prior. The devs tweak the kernel to get better performance and battery life. Adrynalynes 2.0 is good. Dont worry about quadrant scores/ speeds as they are bs. I am also not a fan of overclocking, just my preference.

im not sure exactly, but without getting too technical, it controls your processor speed.
it can make your phone faster, smoother, and more efficient.
if you flash a good rom, i see your on das bamf, it already has a decent kernel.

Check out the section on kernels on wikipedia, it does a decent job explaining it. The reason you might want to run a custom kernel is to add support for something that is disabled in the stock kernel config, like extra filesystem support or tunneling or to undervolt the processor to save on battery. More slots can be added so you can change clock speeds, etc.
Hi folks, first like to say thank you to everyone who puts this stuff together- mindboggling for me so it is.
ANyway, im not a techie, but im getting there.
I've rooted my S2, and i now have CWM and superuser on the phone. I have read ALOT of threads , and i'm a bit confused about my next steps. I have no sd card.
I want to get one of those ROMS to help the battery and all the other jazz(phone call recording sounds particularly sweet), but im wary of jumping into it... I have android 2.33 on the phone, and it was the kf3 kernal that i flashed on with ODIN to ROOT the phone successfully;
Q1. I was thinking of the lightning ROM for my phone- do i need to check which kernel and android version i have and match them up with a specific version of whichever ROM i go for?
Q2. Do i have to 'wipe' the phone before installing the ROM? ( i dont know what this means)
Q3. with the above in mind, can anyone point me towards a detailed tutorial on putting a ROM on the phone? ( i have looked honestly, im not being lazy- they dont seem to say what to do if youve already rooted the phone)
EDIT Q4- Should i have NOT rooted with KF3 V 4.0 and just installed the litening ROM, which would have rooted the phone aswell? - I'm really confused. Basically i can't figure out if ive made it harder to put a ROM on there, or easier.
EDIT Q5; will this method work ( im still not sure how to identify what rom fits my system)
How to install a ROM using CWM
Installing a ROM using CWM is a lot less hassle then installing via Odin. The ROM developer will specify which method of installing their ROM you can use, but it is usually done by a CWM flashable .zip.
To flash:
1. Boot into CWM as described above
2. Navigate to 'install zip from sd card'
3. Select it, and then navigate to 'install zip from sdcard' again!
4. Select the ROM you downloaded from your sd card
5. Navigate down to yes
6. Let CWM install you new ROM!
Many Thank yous in advance for anyone who can help this cabbage (ie, me).
Cheers

A1 No, lighting Rom includes its own kernal and will update your phnes android version when you install it.
A2 you should to make sure their are no stray bits of data floating around. Go to cwm and put it into recovery mode. clean the cache, the go into into advanced and clean daavik cache.
this is what is mean by wiping the phone. if you want you can also do a factory reset.
A3 the method in in question 5 is the usual way to do it from cwm but make sure that you copy it into the internal sdcard.
A4. rooting makes it easier in as it gives you access to the file structure of the phone. It is always a good idea to root the phone, if you want to customize it.
A5. To use cwm mwthod any rom has to come it a zip file version. Tar file versions are used with odin but in any case always follow the developers instructions to get the best out of the rom.

Hi Cosmic blue,
thak you so much for coming back to me, i really appreciate it.
So if i can just clarify my proposed method then from the above with a few more questions;
1 go to cwm recovery and clean the two caches you mentioned above while in recovery mode. ( i see the menu now in recovery mode- would i be right in saying the ones to select are 'wipe cache partition' and i can see the dalvik one in advanced no problem)
2 I need to get the rom zip file from the developers thread. SO i download that to my laptop- then whats the best way to transfer to the phone internal sd card as you said...Do i Need an external sd card yes? (sorry, i know this sounds dumb )
3 ( please ignore this one if youre busy- no big deal as i can do more research) can you recommend a good ROM thats not majorly complicated, saves the battery, looks cool i suppose and has some good extra fucntions? as i was saying i liked the lite'ning one but ive read some places that its a bit of a battery drain...
Thank you so miuch again, its so appreciated.

1. correct, wipe those 2 to prepare your phone.
2. no, you do not need an external card. Go to the laptop root directory, you will see the internal sdcard of your phone as a drive, create a new folder in the phone sdcard and copy the zip file to it.
then detach cable and go into recovery and flash the zip file.
3. you will need to experiment with different roms. Lite'ing is fine all custom roms are a bit of battery drain because of the extra functions. But the battery life is still better then the stock as they have tweaked the battery to discharge slower for longer battery life.
4. Everyone has different preferences. try different combinations of firmware, kernal and modem till you find one that you will like.
hi,
this ROM works very nice for me, thanks all the deveopers!
i have few questions:
(1) since this ROM has OTA updater (it seems, from the changelog), next time when the new version is realeased, can i just update the ROM via OTA updater?
(2) i dont really understand what “Wipe cache/dalvik” and “Wipe data / factory reset” really do. my guess is that “Wipe data / factory reset” repartitions the internal flash memory of the original memory, so we can use all the memory for our purpose. (not like original Nook Tablet, in which they dedicate only 1GB for personal usage)
if i understand all these correctly, this means next time if i flash the new ROM and want to keep the old data, i should not do "Wipe data / factory reset", but only need to do "Wipe cache/dalvik"? is this correct?
thanks so much,
Jun

Wipe data/factory reset is an option in CWM Recovery. Really all it does (from the screen messages) is format both /data and /cache.
Assuming you have CWM Recovery (though I imagine that there are similar entries in TWRP, I've just never used it), to wipe both of the caches you will first need to go to the entry "Wipe Cache Partition", which I believe is directly below Wipe Data/Factory Reset. Do that 3x (that's always been the recommendation, anyway) then go to Advanced and click on Wipe Dalvik Cache (again, 3x).
Again, assuming CWM Recovery, when you're in the recovery Vol Up/Down goes up and down in the list, the 'n' key is for Enter, and the Pwr button goes back.
I don't know about the OTA Updater. I always download and install ROMs (on both my phone and my NT) via Recovery.
Since this is a CM10 based rom you probably don't want to do the ota updater since that is a Cyanogenmod feature. This rom is optimized for the Nook from the CM10 Source I would presume. I personally tried the ota uldater since i get the notifications all the time but i get an error message something like "can't verify the source with a string of numbers". Stick to the recovery based flash installation.

I agree with liquidzoo that you should probably do the wipe cache, wipe dalvik cache and factory reset 3times seems like overkill but you can never be too safe. Also i use twrp recovery and click the system button and wipe system a few times as well.

I'm not picking on you personally, but deleting and/or wiping partitions (in the case of /system) or directories (dalvik-cache) three times as opposed to once is completely unnecessary. You'll gain nothing by running the command three times over running it once, assuming you received no errors the first time.
When wiping the dalvik cache, both CM recovery and TWRP perform an "rm -rf /data/dalvik-cache" command using the shell. It's not Windows, and is unlikely to fail when passed the "-f (force)" option along with the "-r (recursive)" option.
In the case of wiping the /system partition, again both CM and TWRP write out zeros to clear the data on the partition. I would be suprised if CWM acted differently from CM and TWRP when wiping dalvik-cache and /system.
The only reason I bothered to look into what these commands actually do is to prevent a user from thinking there's a corellation between a failure to wipe 3x versus a problem they're having. If a 3x wipe "fixes" something for you, whatever the problem was, it's very unlikely that the second or third wipe was what fixed it but instead it was more likely a result of a clean install of the ROM.

Have fun modding!
No worries, it's just something I've always done as it's been recommended to me in the past (there are some ROM developers that recommend 5x, actually). I'm not saying that 3x over 1x is any better, but I've never had issues. YMMV, but it doesn't take much more time and I like being thorough.

sorry, but can you confirm that when i upgrade to the new ROM (from the same author), it is really necessary to Wipe cache &Dalvik cache?
i am confused because somebody told me that i can just flash the ROM by installing the ZIP file (containing the ROM), and reboot the Nook without having to wipe or clean anything.
thanks,
JK

I don't know if I am doing it right or wrong but I have flashed numerous ROMs and lately have flashed every version of SGT7+CM10+Cherry Picks,By meghd00t. from 24/09 thru my current installation of 08/10 with only one glitch and that was when I flashed enhancements v2 on top of v1.
I have never had any other issues with the above mentioned ROMs except when I flashed 04/10 with enhancement v2. I didn't have the tablet option.
The way I do it is as follows:
1. format /system
2. format /data
3. Flash ROM
4. Flash CWM emmc
5. Flash GAPPs
6. Reset Factory/format data
7. Remove CWM SD card put in data SD Card with Flash Player (no longer avail on Google Play)
8. Boot from CWM menu
Takes awhile to boot this first time. When booted up I bypass the setup screens.
9. Manually set up wireless (need to access auth web site at work and need wireless to be working to accomplish that)
10. Browse to a web site and get redirected to auth page.
11. Auth
12. Set up Google account and other settings, especially under Security <Install from other locations>
13. Download apps I want from Google.
At this first boot SD card is not mounted.
14. Shut down and do a cold boot.
Now I can see SD Card.
15. Install Flash Player from External SD Card.
16. Install Crackle from Play Store.
Now I check Pandora for Audio, Crackle for Video, other apps I use, utilities, keyboards, launchers, games, etc.
So far since Version 24/09 everything has worked for me with the two exceptions above, tablet mode with 04/10 with enhancement v2 and when I flashed enhancement v2 over enhancement v1.
I am now running 08/10 and am very happy with the performance, battery drain is more than CM7 but that is to be expected from a fairly new ROM but not so bad that it is unacceptable, to me at least.
I have never had a black screen or arbitrary reboot (knock on wood). However I do turn my tablet off when I am finished using it, so don't know about deep sleep. I'm using OnDemand, and three launchers without one being the default....Apex, Nova and Trebucket.
All I can say is these developers really ROCK, way to go guys!

You don't need to re-flash CWM every time you flash a ROM. Also, it doesn't make sense to me why you would do a factory reset/format after flashing the new ROM, I would think it would be done prior to flashing the ROM but maybe it doesn't make a difference, I don't know.
I've got TWRP installed to the emmc so I just download the new ROM to the SD with GooManager, reboot into recovery, do a backup, factory reset, flash new ROM & GApps and reboot. Only takes a few minutes.

Tried it as you mentioned, doing a factory reset before flashing the ROM and got a black screen and wouldn't boot. May have been a fluke but the way I mentioned above gives me a good image and alway boots. Don't know why, but if it works for me, I will continue to do it this way as long as it works for me. I have flashed numerous other ROMs the same way with good results each time.

sorry, but can you confirm that when i upgrade to the new ROM (from the same author), it is really necessary to Wipe cache &Dalvik cache?
i am confused because somebody told me that i can just flash the ROM by installing the ZIP file (containing the ROM), and reboot the Nook without having to wipe or clean anything.
thanks,
JK

For an update, yes it is recommended to clear both caches. To be clear, this is only for an update. If it is a new ROM, or if the author recommends it, you should also wipe /data and /system first.
You can just flash without clearing them, but you might run into unexpected issues, so it's not recommended.

Tried it as you mentioned, doing a factory reset before flashing the ROM and got a black screen and wouldn't boot. May have been a fluke but the way I mentioned above gives me a good image and alway boots. Don't know why, but if it works for me, I will continue to do it this way as long as it works for me.

I get a black screen for a while on first boot too, but it only last a couple minutes at the most and if you shine a bright light at the screen you can see the CM logo spinning. Are you sure it was hung?

When you clear the Dalvik cache, it clears out data stored in your applications. When you turn on your Nook after clearing the Dalvik, the first thing it does is it rebuilds the Dalvik cache, that's why it seemed like it hung on startup. I believe the long black screen in the beginning is when it rebuilds Dalvik for core Android apps and then when it says "Optimizing Apps", that's for the rest of your applications. The more apps you have, the longer it will take to build the Dalvik. No need to freak out, just a little patience is all you need. Correct me if I'm wrong, however, as I'm still pretty much a noob at this... :laugh:

Well fhe screen was black, no light at all and I waited for over five minutes for the Flash Screen to come up and it never did. Yes I know when you are waiting time drags. But due to the ROMS always taking awhile to boot up the first time I actually pay attention to how long it takes. No more then 2 minutes in my experience. I had to hold the power button in for a long time until it finally booted in B&N Recovery. Used my sequence mentioned in earlier post to flash the ROM again and everything worked as it should, GREAT. The number of APPs shouldn't be an issue as these ROMS only have the very basic apps.
I have read this forum and see the various and asundry errors some are getting, so far I have never gotten a major error, except for when I forgot to do the Wipe Data/Factory Reset after flashing.
I also got the "No Tablet Mode Option" with 04/10 with enhancement v2.
But I consider these minor issues and currently am running 08/10 with no issues, works smoother then any version of Microsoft Windows I have dealt with.
These developers are exceptional.

I don't know if I am doing it right or wrong but I have flashed numerous ROMs and lately have flashed every version of SGT7+CM10+Cherry Picks,By meghd00t. from 24/09 thru my current installation of 08/10 with only one glitch and that was when I flashed enhancements v2 on top of v1.
I have never had any other issues with the above mentioned ROMs except when I flashed 04/10 with enhancement v2. I didn't have the tablet option.
The way I do it is as follows:
1. format /system
2. format /data
3. Flash ROM
4. Flash CWM emmc
5. Flash GAPPs
6. Reset Factory/format data
7. Remove CWM SD card put in data SD Card with Flash Player (no longer avail on Google Play)
8. Boot from CWM menu

oh, so you always reset factory every time you upgrade the ROM? that way will delete all the old data/apps you installed, so you need to install all the apps again?
this is my concern, because i dont want to reinstall apps, or lose my data. so i think i just need flash the new ROM, then Wipe cache/Dalvik cache, and hopefully all the old apps and data are still intact.
thanks.

i have some questions on the "Enhancements":
(1) the correct way to install them is to flash version 1 first, then immediately flash version 2 right after version 1 (without having to reboot first)?
(2) i am not sure what i will get with this "enhancements". they will make video/audio playing more smoothly? is the quality improvement really noticable? anything else, like they make the battery last longer, for example?
thanks,

If you're running 08/10, the enhancements are not needed. That's my understanding at least. I had problems with V2 so I decided to not install them while on 04/10.

If you flash enhancement v2 on top of version 1 you will have problems, UI will stop. If you only flash v2 you will not have the Tablet Mode Option. So my understanding is that you can use either v1 or v2 but not both.
ROM 08/10 does not need either enhancement as indicated by the developer. ROM 08/10 works great by itself is my experience.
If I'm installing a ROM, backup the existing ROM and wipe everything.
If I'm installing a .zip package like GApps or an enhancement, backup the existing ROM, wipe Data/Dalvik.
Folks, these are development ROMS. Thar be bugs in thet thar code. It's going to take you longer than the time you think you're going to save by doing a dirty flash, and then having to restore the thing to stock (worse case) only to start all over.
Don't ask how I know.

so it is possible to back up the existing data/apps, then restore them back after the new ROM is flashed? could you please confirm this?
if so, how & what is the right steps to do the backup? can we still use CWM, or use ROM Manager, or other tools?
thanks
