hi
I have a samsung note which i rooted when i bought it. when i go to recovery mode sig cwm and trying to install this auto brightness mod from this thread
http://forum.xda-developers.com/showthread.php?t=1373008
I get the error
E: failed to verify whole-file signature
E: signature verification failed
any ideas what could be causing this? Im pretty new to android... used to have an Iphone
ps: when I start CWM it says "This version of CWM manager should be used with CF-Root v5.0 or newer.
It appears you are running a different kernel. Various features has been disabled."
and also when entering recovery mode I get an error which says "Can't access to '/system/csc/XEF/system/"
my phone is a mess now ((
ive flashed kernel with cd-root 5.0 ..then seemed like cwm issue was fixed
then i added auto brightness update and now the phone is totally messed up :O
when phone started it didnt ask for pin... i keep hearing the samsung boot sound and the screen goes on and off with menu showing..
please someone help the noob (
i am able to go to recovery mode...any chance i can redo the last mess i did??
Ok, hope you have made a backup (nandroid or Titanium), because now that you are in this situation the best way to recover is to flash an other ROM (custom or stock) and wipe cache & Dakvik-cache, depending if you use a WIPE or NON-WIPE Rom, you might get back your "stuffs". Try first to flash a Stock NON WIPE ROM for your country for ex. and clear cache and dalvik and see how it goes, you might have to manually clear data from som apps that will FC (or even uninstall and reinstall them if clear data is not enough) but has long that you have access to CWM your note is not brick you can always "repair" it good luck.
When you wanted to try patch/mod apk:
- first verify it apply to your build (KKA or such)
- second do a nandroid, and if anythings goes wrong you can always restore to previous state
Good luck
PS: for the kernel missmatch it is not that big of a deal, some kernel have been built in order to have access to some features from CWM from the running OS itself while other does not, but has long that you can go manually in CWM you can do manually all things from there

thanks for the reply..
another noob q... when I rooted it the first time I just put the stock rom onm y sc card and flashed, but now since it wont go to the phone menu, my pc cants see my phone...
so the question is, how do i put the rom file on the phone to flash it?
I dont have a microsd reader either
btw
i did take a titanium back ..its on the phones sd card
Ok, do you have another phone or sdcard reader somewhere, in order to transfer the ROM in it then you can put it back in your NOTE and flash it. If not you are in a not so good situation, you can always go to CWM plug the usb cable, go to advance settings mount the sdcard and with adb you can push the ROM in your sdcard.
For adb, you have to install KIES to have to right driver, then download adb from android sdk then from a command prompt go to your adb folder (put the ROM in it) and then from the command "adb push MYROM /sdcard/" and you you should see it transfer to your sdcard.
For the titanium, it will be use only if you use a WIPE rom and once booted OK install Titanium and restore everythings. GL

I used odin to flash the stock rom, rooted & now restoring now with titanium everything seems fine & dandy ..
Im not gonna touch anything until the ICS is out ..hehe
Merry xmas to you!
This little issue should not scare you that much, the things you should remember from that is to always make a nandroid backup before falshing anythings or changing things.
Do not stop "messing" around your phone because a that experience, go for it but REMEMBER ALWAYS HAVE A VALID BACKUP.
Merry Xmas to you and all the other too

well ..titanium backup screwed me pretty good... apparently sms/contacts was not backed up by default
For contact use google sync and your google accounts
For sms use SMS backup and restore or some other backup (some apk can backup your SMS in your gmail account also)
Sorry to hear for your "lost"
That is why you should always have a nandroid to be able to extract what (backup the working one, restore the old one backup your contaact and email, then restore your new ROM and restore your missing stuffs) is missing and restore to your new ROM

It was my own fault. I took for granted that titanium backed up everything by default I acrtually had sms backup/restore on the phone.. hehe
well... these stuff happen when Im on new platforms. Im gonna go trough this forum to figure more about flashing costume roms.

I haven't used adb cuz i havent been able to set it up. But i have flashed Damaged control succesfully by mounting the zip on the sd card. i flashed it a couple times since ive tried installing Nexus one launcher by flashing from sd card but nothing just messed up rosie. i couldnt restore my older Rom it kept telling me use adb. Fail lol but i flashed damage control 2.05 back and working fine maybe faster. What i want to know is how to get the nandroid restore fixed or working for emergencies.
alt f4 fixes it all
huh? Confused..
he was trying to be "smart" and gave you a bogus answer if you combo press alt + F4 it will exit your screen... Not really sure what your question is though if you are asking as to why your Nandroid won't restore properly it's because you have to "wipe" your cache before doing a nandroid if you are going back to a version that is different than the currently flashed rom. Hope this helps if not then ... perhaps you could re-phrase your question.

The only way I fixed that is by running the nandroid restore through adb like it says to do. I don't understand how you don't have adb installed but you have the phone rooted? I had to get all that working to root my phone and having adb is an invaluable tool anyway.
I did read that the nandroid error sometime comes up when the sdcard is too full so you could see if that is the case. Also, as someone suggested you could try a factory reset/wipe and then try again to nandroid through recovery.

Yup,i don't even have a pc (seriously I don't)
I did run into this problem though, not sure exactly what I did but it worked itself out, maybe try flashing a different recovery image,Or try keeping phone plugged into charger(not sure what significance that has but it did seem to go for me after I was having those problems) which recovery image do you have?
Did you rename the Nandroid backup you were trying to restore to? If you did, and the file name has a space in it, it will tell you to restore via ADB. Just a thought from the limited info you provided.
I had this problem and it fixed itself out and all i did was wipe everything thats under the wipe option in recovery and it worked for me.
Yeah it was actually the cache you guys were right. i did it on my own and thought that might be it. and now i know that was it from checkin the thread. yeah i used pre kitchen to auto root my phone. im actually running damage control 2.05 now the newest sprint leak.damn i love it lol. but imma reflash it cuz i tried to flash a nexus theme/ no luck i want a nexus one interface!!!!!
I'm looking to upgrade my phone to a custom ROM, but I'm not sure which one is the best for my needs. This is what I am looking for:
Fyro Update
Increased Phone Speed
Increased Battery Support
Adblock for browser and apps
Also, how do I flash my ROM? I have the drivers to connect my phone to my computer, and that's about as far as I got. Secondly, will I lose my apps and their data? I already have my contacts and SMS backed up.
Thanks guys
jt
As a shameless plug - I whole-heartedly recommend SyndicateROM. It'll fulfill three of your four features already (including ad blocking in apps and the browser), and when the OFFICIAL, FINAL (ACS prides itself on stability and feature-completeness) Froyo release is out, it will be updated right away!
That's actually the one I was looking at. Is there instructions on how to flash your ROM? Will I lose my apps and their data?
After rooting you'll need Clockwork Recovery mod(CWM). Look for a Dev who has created a root with a CWM install (http://forum.xda-developers.com/showthread.php?t=770388).
1. Follow steps to root and install CWM.
2. Download a ROM and put it on your SDcard (Start with ones that have been around for a while and have been tested quite a bit. Avoid Froyo ones till you feel comfortable with CWM and Odin {if you ever use it}).
3. Reboot into CWM, BACKUP everything (this is key for your data to come back), wipe x3 (including cache)
4. Install ROM from SDcard(reboot, may take a few minutes to load for the first time)
5. Reboot into CWM, and advance restore (DATA only). reboot
6. Enjoy with all your data.
Hope this helps
Epic Experience + Phoenix is the best battery life I've had on any ROM.
Performance feels like stock, which is to say, this phone is really fast just as is and I don't think its screaming for better performance out of the box. Its not like it feels sluggish like the Evo does.
All these devs do great work! You can't go wrong with any of these roms. This belongs in the General Discussions section!

camera button, down volume and power on.
I suggest you try them all and figure out what you like or don't like. Also try out the ODIN program so when you accidentally bork your phone you will know how to fix it right away.
Got it. I assume this is backing up to my SD card. Do I not wipe my SD card?
Thanks, this should be the last question!

The only way you will wipe your SD card is if you partition it for A2SD support. The factory reset wipes all your data and might be a good idea if you are going from one rom/kernel to another. CWM backs up to your SD card. I have about 6 backups and can restore several different roms if I want. If you try all the roms out and make backups of all them it will be easy to go back to what you want.
A program called ROM Manager will make it easy to rename your backups.
I've had such great help in these forums (Nook specifically) I couldn't resist trying my luck in these (Droid X) forums as well.
So, I've searched for Clockworkmod threads but they are all (That I found or noticed) from back in August.
Plenty of info to be had on Titanium Backup.
So my question, is Titanium the backup/restore program of choice? I was hoping for an idiots guide to backup and restore (especially in the event of problems) but the guides are kind of sketchy on the restore part.
Titanium
Use titanium backup to backup and restore all your apps. Useful when trying out new roms, although without the paid version of titanium you will spend alot of time tapping through the installation screens as it goes through your apps. Titanium won't help you recover a broken system.
SBF
Use RSDLITE 4.9 with a .SBF file to perform what many call a "sbf". This is usually used to restore a phone back to stock, or to recover from a bad/corrupted operating system. If your phone is unbootable, this is your recovery option. SBF'ing your phone is not as scary as it sounds, just download the system restore file (.sbf), connect your phone via usb to your computer, and use RSDLITE 4.9 to flash the phone.
Nand backups / Clockwork recovery
Use clockworkmod to do a full backup of your phone. Think of it as a clone of your phone. Restore your phone by booting into clockwork recovery and instead of choosing "backup", use the "restore" command. It will then allow you to select one of the backups you have made with clockwork. Pretty easy stuff here.

Thank you, this is exactly what I was after. My only problem remains that I do not see any guides on how to go about downloading/installing/operating this program. I'll keep searching now that I know more about what I'm searching for. Thanks!
Search the market for "rom manager", it's free. Load it and tap "flash clockworkmod recovery".
You can use this app to reboot into recovery or by holding down the home and volume down buttons while pushing the power on button.
You can also download the DX bootstrapper from koushik's site, just google "koush bootstrap". Also free.

Woah there buddy.
I'm going to clarify this process a bit for you before you mess something up, if you don't mind.
Root your phone.
The simplest method is to search for Z4Root here in the forums...it's a .apk that roots your phone for you.
Now...
I assume you want a sweeeeeeeet rom, ya?
We can do that...
MY personal recommendation would be this...
Make sure you have at least 2-3 gigs free on your SD...it won't need to STAY that way...but during this process, it will.
Open your contacts.
Click the options button.
Backup your contacts to your SD card.
Now download Titanium from the market...
The free version works fine for 99% of what you need.
The only problem is (as mentioned) you have to manually click the "install" button for all 500098098098 of your apps when you restore...as opposed to just one button and letting it work for a few minutes.
Open Titanium and backup all of your apps+data.
Do you want Liberty 2.0? I personally use it and LOOOOOOVE it...but you currently have to pay $5.99 for it...a free version should be released soon.
If you do...just download liberty toolbox donate from the market.
It will install the rom for you! The option is under the "Rom Manager" part...
Make sure you select both options when installing....The "Backup" and "clear data" ones.
If you don't want liberty...read below...if you've chosen to pay the $5.99...skip down to the ****** below.
Download either DX bootstrap or Rom Manager.
Rom manager actually installs Clockwork...where bootstrap is simply a method of booting into clockwork via an application.
Either work fine.
Find the ROM you'd like to install and download the .zip
Put the zip on the root of your SD card.
Boot into clockwork.
(With DX bootstrap you click "bootstrap" and when it finishes click "reboot recovery")
Backup. (Camera button selects options, volume moves up and down, and power moves back a page)
Now Wipe Data/Factory Reset
Now...Wipe Data/Factory Reset
And again.
And again.
I usually do that 3-4 times just for extra security.
Now install zip from SD card.
Pick the "Choose Zip from SD card" option.
Find your rom's .zip
Click Reboot.
******
CONGRATULATIONS!
You're running a custom ROM!
Now...if you're contacts don't automatically start restoring...
You can choose the backup that you made from the options menu in your contacts.
Now...restore all apps+data with Titanium.
And you're back to where you were before the rom.
All your contacts...all your apps...
You may need to go back into your settings menu and change those back to your exact specifications.
Now...
If you don't like your rom...
You can boot into recovery again...
And restore to where you were previously with one click.
At this point after deciding I like the rom (I don't keep much free space on my SD)
I usually move my nandroid backup from before the rom to my computer...and delete it from my SD card...and then do another backup of my current (rom'd) setup.
I keep a copy of the titanium backup on my PC as well...and delete it from my SD card...there is no reason to waste a gig of space that can easily be transferred back when needed.
My recommendation is to always have you're most recent nandroid backup on your SD card and a copy of your last few on your computer.
You can rename the backup folders for organization...but don't use any spaces or special characters.
If you're REALLY hurting for space...
You can delete the nandroid backup safely if you have a microSD reader on your computer...in the case that your phone doesn't work and need to transfer the backup back onto your SD card.
Happy modding!
Thanks for the info, all of which answered my question just right. I've been using Gingerbread rooted & deoxed since Friday and it is quite nice. The improved battery life is phenomenal!
I want to STRONGLY recommend that everyone who is new/does not know what they are doing actually go through the process of flashing the rom. I was inexperienced once and I hard bricked it (unfixable). No one needs to go through that and anyway that's what keeps our bootloaders locked.
INCREDIBLY IMPORTANT STEPS
If you do not wipe data/cache/dalvik cache/battery stats, you will bootloop. Repeatedly wiping is not at all necessary but its good for ocd.
If you do not mount system and data, your phone WILL NOT BOOT and you will have to sbf.
SBF'ing is not difficult but a pain in the ass. First of all you do not need version 4.9. I used 4.7 three days ago to flash the most recent system version. Make sure that you have the file for your bootloader version or again your phone WILL NOT BOOT.
That being said, I have found that all problems are almost always careless mistakes or at least mine have been
You will find that as long as you're careful and follow all instructions, you'll never have any problems
Ok. Great info. I have been reading through the stickies n then came across this.
I am currently running darkslide 4.2 with blur. Flashed using clockwork mod on DX rooted with z4. I know that's alot of acronyms but yall understand. I used the bootstrap to get to clockwork and load everything using astro file manager.
Here is the question.
Do I have to wipe my cache in clockwork or can I leave it? So far I have left it n its running fine but doesn't seem any faster and my battery runs down in about a day.
I also use Titanium to back up my stuff but do I ha e to back up everything manually or is the free version one touch good enough? I noticed there are alot of things not backed up in to do list. I will happily get the donate version if its recommended.
Thank you all for your time and effort to answer our beginner questions.
Sent from my DROIDX using XDA App
Glad to see you are making progress, jperro. It never hurts (in my experience) to wipe the cache.
The paid version of Titanium backup lets you perform batch operations without interacting with every single install screen. There are other features that make it good, but thats the main one that saves you time/frustration.
I only back up a few system apps/data like Contacts Storage and Wifi Hotspots Storage. If I'm restoring my phone, chances are I'm either trying a new rom and I don't really want to muck it up with any old data - so I don't back up all the system apps/data that Titanium Backup shows as "not backed up". Besides, I've got nand backups in case I'm flashing back to a previous setup, so restoring system data or apps via Titanium seems redundant.
Ahhh. Ok. Thanks jeftep for the info. Very useful and informative.

Hey all,
I was trying to get OTA2 installed while retaining my root and long story short I ended up formatting my /system in CWM thinking it would rebuild the factory image. Now of coarse my system won't boot. For some reason I am also unable to mount /sdcard. Is there anyway I could restore my system?
Thanks for any help!
restore \system of your CWM backup
I don't have a CWM backup . I know, a real bonehead move. If anyone could help me out with a clean CWM backup I'd be willing to compensate.
Edit: BTW I have a 16gb US version of the TPT.
Is it even possible to flash someone else's CWM backup?
Could I use the full image that Lenovo took down, found here?
I don't suppose there's an nvflash image for this device...
While I'm not sure, it might be possible to use that full image. Certainly worth a try. You might try asking on that forum, if you haven't already.
Yes, It is possible to restore from someone else's backup. I, in the past have copied my backups to my pc when they were too much and If i needed them, I just copied them back to external_sd/clockworkmod/backup/ and voila, it would appear for restoration in CWM.
I may be wrong, I do not believe that region should have any effect but to be safe (since you already made one mistake ) restore your US version with a US backup. I have a UK version and I would have uploaded a backup for you if you couldn't find a US one but unfortunately, my tablet is at the lenovo repair centre, being treated for the dreaded micro usb port failure. Hope someone here can help with a backup.
Thanks for the advice!
I downloaded that full image, but I could not get it to flash in the traditional sense. I extracted it and copied the system directory to my system partition and the tablet actually boots now. However, wifi does not work, whenever I press any of the menu keys a red frame flashes around the screen, and I cannot go to the About section of the settings to try to download updates or anything, it just crashes. I am also unable to update to OTA1 via zip in CWM, it gives me:
Code:
assert failed: file_getprop("/system/build.prop", "ro.buildfingerprint") == "Lenovo/ThinkPadTablet/Indigo:3.1/ThinkPadTablet_A310_02/0024_0065_US:user/releasekeys" || file_getprop("/system/build.prop","ro.build.fingerprint") == "Lenovo/ThinkPadTablet/Indigo:3.1/ThinkPadTablet_A310_02/0037_0075_US:user/release-keys"
Since you still need a lot of help anyway why don't you try manually installing all of the updates up to OTA 0076. You have to have all the updates before it flashed first. Link here:
http://download.lenovo.com/slates/think/tablet1
The nandroid backup would have to be of a factory restore, correct? Otherwise, all accounts/settings, etc would be within the backup as well.
I wasn't planning on doing a factory restore any time soon, but if the CM9 ICS port releases is soon, I can make one then as I have the same model and region as you.
I'm just really busy at the moment due to school and I rely on my tablet for school!
That would be the only safe way to let someone have a backup.
toenail_flicker, Thanks for the suggestion, I'll start from the top of the list and work my way down.
obscure.detour, being a student also, I completely understand. Luckily I just bought a Livescribe pen to offset my need for my TPT for the moment .
In the mean time, in case anyone else would be willing, you could also take a backup of your current system, do a factory restore, take a backup of the clean rom, and than restore your original image.
Thanks!
LOL You make it sound easy, but for a CWM noob it's a dicey thing. Never restored anything. Perhaps someone with more confidence in CWM than me can pull it off for you.
I know letting someone have a backup that contains personal info my be tricky, but if you've got time (couple of hours) on your hands you can backup your current system, do a factory reset, and since a factory reset only affects data, it wont wipe your root or CWM. you can then make a CWM backup of the newly reset rom, copy it off the sd card and restore your earlier system which you backed up.
This would save the OP having to start installing the OTA updates one by one.
Like I said, my tablet is away for repairs, otherwise I would have helped him. Or, maybe that's a good thing cos its certain that my tablet's main board will be changed, thus its going to be a fresh android installation on it. when I receive it in a couple of days, if you're still in need, I'll try to reroot and install CWM so I can send you a backup.
Much appreciated darkhandsome18! Installing the OTA's failed . It looks like the image I found is actually a test build. Even the earliest patches do not recognize it as a viable base to install on.
Did you ever get someone's backup? If not I can make one for you today. I am on OTA2 though, were you updated before you wiped system?
Here is a CWM backup from my 32GB US TpT.
Extract the file onto your external sd card in the folder /clockworkmod/backup/
Reboot into CWR
Select Restore Backup and select my backup (You can use advanced backup to restore individual parts or just the normal restore to restore everything, which will be factory reset US OTA2 with root)
Hopefully everything will work properly and you will never format your system partition without a nandroid backup again.
I have it on my Dropbox for now but will delete it in a couple of days because it takes up a lot of space. Let me know once you have downloaded it.
If you don't have a Dropbox account then sign up here and we'll both get an extra 250MB of storage space.
jhankinson, thanks! I was not on OTA2, would that be a problem? Also, I'm having issues backing up my current setup, I got ICS running. CWR gives me "Error while backing up boot image". Any ideas?
I'd like to backup my current (semi-working) setup before attempting to restore yours. Thanks again for uploading that!
I finally got it to work by remounting my sdcard in rw using ADB in clockwork recovery. That backup seems to have worked flawlessly jhankinson, I can't thank you enough!
This is great news! I knew I couldn't help you, but so glad GodfatherIP was able to help you. He helped me a great deal, too, recently.
Who is GodfatherIP?
Some apps not working after updated to 4.2, so I'm considering back to 4.1.2.
Though I never done this before since the day I get Nexus 7,
I think use Wug's Nexus Root Toolkit should get it done.
But just for sure:
1. Do I need to unlock/root to flash factory 4.1.2 image? (I think it is not but not so sure)
2. Directory structure seems different from 4.1.2, is it OK just using Toolkit to backup/restore settings?
(Sorry for my English if anything looks impolite)
1) unlock bootloader yes; root no, as you're going to overwrite the system anyways.
Also I'd suggest not using a toolkit, just download the factory image off google's page and run the "flash-all.bat"
2) Use Titanium Backup to backup all app data, wipe after flashing 4.1.2 and then restore apps + data with Titanium again
I just downgraded this morning. All your data will be wiped .. ALL YOUR DATA ... meaning, after I got back to 4.1.2 I was having 13GB of free space on the tablet (out of 13 possible) .
So, if you HAVE a nandroid from the 4.1.2 days, save it to your computer (along with all your files).
If you don't have a 4.1.2 nandroid, at least create now a backup repository with whatever tool you prefer and then save the respective files to PC.
Then, flash the factory image for 4.1.2.
Then copy all your files back to the internal memory, install the backup tool and restore your apps.
The reason behind this is that the update from 4.1.2 to 4.2 has some scripts that are porting the original /data and /sdcard mounts to the new structure used in 4.2
When downgrading, you no longer have scripts to do that for you so the newly installed 4.1.2 will not recognize anything so it will bootloop like crazy (I tried first to restore just the /system ... but all the other data was already affected by the update so was no longer usable).
My thoughts:
If you got the ota, and things messed up, try flashing the 4.2 factory image. That seemed to help me. If you're not rooted already, I would recommend becoming familiar with the adb backup command to backup apps before doing anything else. You have to unlock the boot loader to downgrade or flash the factory 4.2 image, and this will wipe the device.
Once you update either way, definitely take the time to root. You can then use adb restore or titanium backup to restore from the adb backup you made before unlocking.
Just be aware that adb backup doesn't seem to backup all apps, and that titanium backup isn't exactly fast parsing through a big adb backup file.

1) unlock bootloader yes; root no, as you're going to overwrite the system anyways.

Assumed you are referring to downgrade from 4.2.1 to 4.1.2 and rooted to run TB, so the basic stock rom is up & running otherwise, correct?
Let's try Plan B instead - go into (Custom) Recovery and wipe dalvik cache first, then reboot. Give it a few minutes to settle and try to do your TB restore WITHOUT data, and see if it works. The /SD and/or /SD/0 directory structures are setup differently on the N7 and trying to retore with your custom settings will just make it more difficult & complicated. If this works, you can then try to selectively restore one or more with data and hopefully without going into endless bootloop again.
Plan C - go to Play Store, then Settings and "All" - you should see all of your Apps and what's installed, etc. - and install from there, it's semi-manual but it works for me 99.8% of the time when it would otherwise freeze within TB, especially true when switching custom Rom & kernels.
I usually manually copy & move back items such as documents, pictures & mp3's, etc. from standalone/usb backup drives or cloud storage back into the device once everything else are up & running properly.
Let us know if this helps & working for you or not.
Thankss !

Thanks for your help , but I think the problem was that there were apps in the backup only compatible with the custom ROM I had and android 4.2.1 xD
I restored the apps one by one , but I think if I deleted the extra custom rom apps , the process would have finished without any problems
Hi fellow people,
i'm a noob just made my xda account like 5 mins ago. I've been trying to search for my problem but I haven't really a found a direct answer. So yesterday I just got my Samsung Galaxy nexus update to 4.2.1. I was really excited until I started having the battery issues, screen lock issues, and overheating problem. I really don't like 4.2.1 and want to downgrade my version back 4.1.2. My carrier is the Mobicility (Canadian). I did not do anything previously with this phone such as rooting it, doing all the funky stuff that will void my warranty. I heard about flashing some google images to get back 4.1.2 but I'm not sure if I need to root or how to like do it through the gnex toolkit that mskip made. As well what if the difference between yakju and maguro? I heard if you flash the wrong image it will brick your phone or something like that. If there is a method without having to root it and lose all my contacts, then I would prefer that a lot.
Thanks,

You dont have to root but you need to UNLOCK the bootloader which will obviously erase all your data(and VOID your warranty). you can find the factory image here https://developers.google.com/android/nexus/images . just flash the appropriate image and you should be as good to go.

mleung754,
You are posting in the wrong forum.
Asus Nexus 7 is not the same thing as a Samsung Galaxy Nexus.
Ignore mmystere68's remarks.
