[Question] how to unroot/restore

Hello,
I recently bought a nexus one from Craigslist. I thought it hadn't been tampered with but it turns out that it is rooted. I read you can tell its rooted when theres an open lock underneath the nexus sign when loading it. I don't know how he rooted but its preventing me from updating to the pinch and zoom capabilities. Always get (status 7) error. So I want to unroot the phone, update it then perhaps later root it. Is there a way I can unroot it with a Mac?
Thanks for the help!

It's rooted without an unlocked bootloader? I doubt that, or maybe you have the only one in existence.
You can always just flash this:

in recovery and you'll get the multitouch update.

How do I update it then? I have always gotten (status 7) error. Better yet how do I unroot it? Any ideas?

As of right now, theres no way to unroot a phone. But if I were you, id consider upgrading it to CyanogenMod (search in nexus one development for it) that enables the multi-touch capabilities.

Its not possible
The best you could do is this, http://forum.xda-developers.com/showthread.php?t=614850
But anyway, why unroot, a rooted phone is much better
How about you look around the site and see wah u can actually do with your phone now

Just look for modaco's 1.7 , download it. Put your phone into recovery by powering down then hold volume down, down while holding that down press n hold power button. A white screen should come up. Leave it be until the green lettering disappears. Then press volume down to navigate to "recovery". Once in recovery use trackball to navigate to USB toggle . Click on it via trackball. Now plug ur phone into your comp via micro USB cable. Go to "my computer" on ur comp. Double click removable disk to open ur SD card. Delete everything from ur SD. Go to where u saved modacos 1.7 drag it to your empty SD card. Now click ur track ball to disable USB connection. Unplug your phone. Go to wipe. Click on it with ur track ball. Now click wipe data. Let it do its thing. Then wipe dalvik cache. Let it do its thing. After that push volume down to get back to ur menu. Go to flash update. Click on it and click on the zip you just put on ur Sd card. Let it do its thing and you're done.

1. Download a ROM of your choice, and then load it on to your SD card in the root directory.
2. Shut the phone off.
3. Hold down the volume down button, and hit + hold the power button at the same time.
4. Continue holding until the phone boots up
5. Scroll down to recovery by hitting the volume down button once.
6. Press the power button once.
7. Scroll down with the scrollball to Wipe
8. Wipe device/factory reset
9. Wipe cache
10. Click the volume down again
11. Scroll to Flash update/zip
12. Scroll to the ROM you downloaded and loaded to your zip, and then click
13. Click the trackball again to accept.
Now, you really just have to make sure the ROM you downloaded has the pinch to zoom, which most have. I don't believe you'll lose root, but you should at least gain the features you're looking for.

Your Nexus One is unlocked, not rooted. There is difference.

Thanks everyone for the help! I ended up needing to install the Amon RA recovery image and then installed the MoDaCo ROM. Works good but I read that Cyanogen is better with better features. I think I will now install the Cyanogen ROM. Not sure what he means by updating the radio if needed though. My radio is RADIO-4.02.02.14
If anyone knows if this is ok then I would appreciate it, I will try to research and see if it's ok too.
Thanks again!

Remember to do a nandroid backup in case you either screws something up or you wish to go back to your previous Rom (saves time and headache).

As far as i know updating the radio is optional, you just download it, nandroid backup, update like a rom, and reboot, IMPORTANT ON REBOOT IT WILL GO TO A LOADING SCREEN WHERE IT UPDATES THE RADIO DO NOT TOUCH ANYTHING OR PULL BATTERY OR YOU MAY BRICK YOUR PHONE-FOR REAL. With that said after the radio loads it will take you back to recovery, then nandroid again if you want(never hurts), wipe and flash cyanogens rom then the gapps add on and then reboot and youre good to go.

I just download all the files but I noticed that the radio is a .img file
Not sure how I can install it... any suggestions?

[ROOT\RECOVERY\ROMS][NX008HD8G] Nextbook 8" Resources

WARNING: These files are reported as not working on Next8HD8G tablets manufactured after August 2013. Check your serial number. If it begins YFG1013... YFG1113... or higher, do not use these files. You may try to root using Cydia Impactor instead. If you do root one of the newer tablets, please dump the ROM for the rest of us!​
Nextbook 8"​
The Nextbook 8 is an afordable 99USD tablet from walmart. Widelly adapted but not with any serious unofficial development going on. I purchased one for a friend and couldn't resist to tweak it. I tried to find some ROMs to no avail. Also rooting was a long journey. So I decided to create this resource thread to help out people to this device and even present my own ROM. So without further to do I begin :​
Rooting & Recovery the Easy way​
Rooting was my first concern so I could de-bloat the tablet itself since it came with various unused software. The most efficient method I came across was the one presented by shaunmt at the freaktab forums here. So let me show you how it's done.
1. Download the modified stock recovery from shaunmt
2. Extract the archive and place the image in the root of your external SD card! NOT THE INTERNAL ONE!
3. Download and copy the root package by Kyser to your external SD card!
4. Power off the tablet and then hold down both volume keys while holding the power button. The tablet should show the first splash screen and then a black one followed by the recovery screen.
5. Use the Volume keys to navigate in the menu and the power button to confirm your selection. Select flash from EXT (or something like that), then select your SD card and then select the root package to install. The root package will be installed. Navigate back to the root mneu and select "reboot system"
6. Rooting should have finished and your tablet once powered on should be permanently rooted. But in the case that you don't see a root management application go to the Play Store and download either SuperSU or Super User.
7. Finished!
ROMs ​
1. Stock ROM - Packed by shaunmt at freaktab - here
2. nextGen 8" - By CedArctic - Comming soon​
Always perform a full wipe when installing ROMs. Neither of these ROMs has been personally tested by me. Shaunmt from freaktab owns all the work on the thread (except my ROM).

Reserved for future needs

Keep an eye on my threads at FreakTab... there is lots more coming soon...

help
i did every step and installation was aborted... any tips?

You don't have the custom recovery file in your EXTERNAL sd card. The stock recovery aborts the installation due to not recognising the google installation keys.

How would I go about dumping the ROM so we can make recovery and a custom ROM. Mine is the newer one. Rooted and debloated
Sent from my MB865 using XDA Premium 4 mobile app

sir shaunmt can you examine my dump files if it is usable in porting any custom recovery in my device? here's my dump file..
http://www.4shared.com/rar/kpulgLt3ce/romdump.html?
thanks for the help in advance..

Same here
I picked one up for either modding or dismantling it to see if I could build it. So the root thing is new to me, I have been spending a few days reading over you guys tuts and suggestions. I came across this one and it seemed fairly simple, take the downloads, extract to SD and recovery reboot? However it has not worked. If I push both volumes I get small yellow script at top saying DNX Fastboot mode, if I do the volume up button with power, I get the options of REBOOT, RECOVERY,POWER OFF, and I believe one other one. Either way I seem to hit a wall. I'm have no doubt it's me, but I would a appreciate a lil advice.
Thank you

NX008HD8G, Firmware? Root?
Hey Guys! I was wondering if maybe there was another link to the files? Has anyone figured out how to update the firmware on the NX008HD8G? I’m having trouble trying to root and I’m unable to find anything on how to at least update the firmware to 4.4.2. I’ve been having trouble with google play services, and could use either the stock rom or maybe a custom. Please help! Hopefully someone sees this!

Rooting NX008HD8G
These files are dead. Is there anything way you could update them? I’m unable to root or even update firmware. :victory: @CedArctic @shaunmt

"AN-21 U" - Unbranded 6.2" 2 DIN 4.4.2 Car Tried rooting now lost BT and WIFI HELP

"AN-21 U" - Unbranded 6.2" 2 DIN 4.4.2 Car Tried rooting now lost BT and WIFI HELP
I tried rooting my device using BAIDU root, now lost bluetooth and wifi and didnt root. HELP!
Android Version 4.4.2
MCU version 4.3.11.1-11-50-454101
Also tried factory reset using the 7890 password but it loops forever. After a couple hours it still doing the factory reset until I turn it off and back on with no changes.
If someone can tell me how can I effectively factory reset this unit I would really appreciate it. Mine has no home button.
Cant get in the fastboot mode either.
I tried pressing the reset button with the power button and it tries to update but nothing else.

Hi!
Excactly same issue here.
Don't know exactly if my equipment is an AN-21 or a variation of. But passwords are the same (7890, 123456 and [email protected]w-desktop) and kind of version it could be. No visual signs outside of the equipment.
Only difference is that has a RK3066 processor.
MCU version: 4.3.10-11-10-450101
System version: 2.9.4_20150316
DVD Version: 2.13.13.1-860mc
Also factory reset didn't work. Re-choosing MCU version inside extra settings didn't work too.
Last resort if there is no answer is try to do image update with same of the Huifei. Seeing the kind of update on the extra settings it appears to be compatible cos has sepperated mcu and firmware updates.
Configuration of the bluetooth is lost, I mean name, pin, etc. and if is not stored when I reconfigure.
The WiFi detects SSID networks, for example WiFI zone of my phone, but doesn't connect with any on the proccess of adquiring IP address saying poor connection quality (not checked on config avoid bad connections).
Waiting for any help before raising the axe!

More info that may help:
Managed to install a system info app. Confirm that my proccessor is an Cortex A9 so it's a variation of AN-21 but 7''.
On About device says android 4.4.2 but the app says 4.2
Hardware appears to function ok and all function managed by mcu,. cos radio, music, GPS, are perfect, my phone connect via bluetooth with the device ok , but on device screen there is nothing detected, perhaps some part of firmware corrupted on rooting proccess.
Wifi has same problem, it detect even weak signas as I drive on street, but can't connect, perhaps same comunication problem.
It seems that is a problem reading and writing parameters, not a hardware failure.
I believe that a reflash of the firmware must solve the problem. But I can't find same release. Perhaps a downgrade is only way to solve the problem by now, my doubt is if the proccess of flashing erase contents (format partitions) for the case any actual file may conflict with the downgrade version.
Still waiting any word of wisdom....

Solved!!!
As I supossed, the problem was some corruption of files, not hardware.
Re-flashed with version 2.9.5 and everything it's working perfect!!!!!!!
No needed to reflash mcu.

So you are my only hope to solve this too

The combination of, from being power-down, reset+power, release reset, 2 seconds, release power, works for me.
Did you tried using the option firmware update from the general settings submenu?
One more thing, reset to factory now also works and it takes only seconds!!!
For the firmware version I downloaded from here
4pda.ru/forum/lofiversion/index.php?t522762.html (sorry I don't have the sufficient posts to be enable to post urls )
If you do not know rumanian, copy and paste the whole url on google and on the find list use option translate. It is not perfect but works for me

Thank you

Your solution worked perfect. Although the display is different now, (not sure if its an upgrade or downgrade) it solved the problem. Im able to connect wifi and bluetooth again!
No back to the original reason for trying to root it was because I wanted to connect a modem and the app for this is for rooted devices.
Any ideas?

Perhaps you downloaded another vendor version, at least I read there are 3 different customisations. Mine is that with the snow and trees background image.
I just terminate tests of rooting. With Baidu 2001 no problem at all, no further corruption of wifi or BT, it has the ability to root. But root is missing on reboot. Have to investigate a little.
Regards.

Where you able to root it successfully?
Im scared now to loose wifi and bt again.

Nahhh, once you know it's not hardware problem, know how to reflash, have the firmware, there's no problem. Always can start over and over.
I will write down the phrase I have on the car forum I modereate, it is in spanish, but can be translated with easy.
"La categoría de vencido sólo se alcanza después de haber luchado y es lo que distingue del desertor y del cobarde"
Good Luck!!!

Getting Closer.
I came across with this feed from the site:
http://forum.xda-developers.com/wiki/Tonghai_Create_AN-21_U#For_Software_Versions_2.7.38_and_up
And is very specify about which app to use depending on the system version. Using the one indicated there, was able to root too, but lost it at reboot .
I thought to share it with you because there were more tips you may find useful.

More info my friend.
Not yet all the work but with good news.
I was reading some posts across the universe, and decided to to this:
1 - format the equipment completly. This is done with a special firmware called fullformat (fullformat.rar on the repository I mentioned to you some posts above)
2 - flash the version 2.8.8 (2.8.8_TT_preroot.zip on repository)
3 - install and run Baiduroot_2001.apk inside the zip 2.8.8
rooted effectively.
3 - install CWM SuperUser.apk inside the zip 2.8.8
runn supersu, update binary (normal install) when Baidu ask for root access (is easy to recognize cos has a counter decrementing on option)
4 - reboot
5 - install rootchecker from play store.
6 - run rootchecker and agree supersu asking permission of root.
7 - uninstall baidu
8 - reboot
9 - re check root with rootchecker and voila, root doesn't dissappear.
Now I am at this point. Very happy indeed. For the time here 22:00hs (I don t know were you live, here is Argentina).
Tomorrow
10 - update firmware with last version 2.9.5 and check for root not lost.
11 - if root lost -> goto 1 and stop on step 9 untill more information to root last version.
Bye!!!!!

Ok, Just go to point 9.
The only firmware that stays rooted is that 2.8.8 permroot thay I downloaded.
With that firmware also works "ppp widget" (version obsolete of widget, not ver 2) with a Huawei 176 dongle.
Bye.

OK now rooted with version 2.9.5!!!!

Thank you for valuable information. I was able to perm root using the previous method and then upgraded to 2.9.5 and tried to perm root using the latest method but when I try to access gocsdk file, inside the sys/bin folder is empty, which suggests me that the temp root is not working although baidu messages ok.
Any suggestions?

Use "RootChecker" for checking rooting process.
I have this problem at first using X-plore as a file explorer with no root access, al directories with no permissions are shown as empty.
I've redone all the process this weekend directly flashing the format firmware, then a fresh 2.9.5, and root whith the process of the post
baidu
move gocsdk to gocsdk.bin
create gocsdk as indicated
install supersu
reboot
check root with rootchecker
remove baidu
reboot
check root with rootchecker
And worked again with a fresh 2.9.5.

How to Root Android 10 Radio

Hi, I am new to the forum and have never done any of this. I bought a Chinese Android radio, and because it lacks several options in the menu, I would like to change the start icon, and I see that to modify the Bootlogo I need to root. I have already done the OEM unlocking, I have tried with Kingoroot, it has not worked, and I am unable to access the recovery menu when starting the system, I cannot find the combination of keys to start it even by pressing the small "reset" button, Its a Fiat 500 radio type. I cant post the link. Thank you very much in advance.

Not Android auto, request moved to Android head units forum.

bootloop on px6 android 9

Hello, I have a Dasaita PX6 with hal9k mod installed and it can't start android, only the android name appears and nothing else. I've wiped from recovery but it still doesn't work. I want to know, if I can install the same android rom through the recovery or I have to follow another method to make it work. I am also talking to the manufacturer to send me the original firmware, but they only ask questions and do not give me solutions at the moment. It tells me to access the motherboard and send it a picture.

thanks for answering. I have seen the tutorial of your signature, but I can't find a tutorial to do it through the SDcard

I have tried to reinstall the rom with an sd card from the recovery and it gives me an error.

I was able to solve it by installing the ROM from a USB. Now it works perfect!!!
