[How-To] ROOT Your Nexus One without Unlocking the Bootloader. ALL ROM'S! - Google Nexus One Owners | Google Groups. Ok, I posted this on my Google Groups page where I was able to Tidy it up and update it easier. Sources credited and applied. I did this on 2 N1's. No wiping, no data loss, both T-Mobile with FRF91. No data loss, no wipes, no nothing. The only reason you will have to wipe or anything is if you want to put a custom recovery on it and a custom ROM.
TRANSLATE from German to English by google.com The boot loader must ensure not be enabled and it works well with FRF91, VF, Korean, etc. Credits: - The Android Exploid Crew: C skills: android trickery - Amon_RA - Cyanogen Notes: - Exploit is not from me (see credits), "proof of concept" for Nexus One created by dolomiti7 http://www.android-hilfe.de/root-hacking-modding-fuer-nexus-one/36923-root-ohne-unlocking-vodafone-korean-frf91-neue-methode.html (German) or here http://forum.xda-developers.com/showthread.php?t=736271 (original tread) - Should work on all previous ROMs - Tested on EPF30, Korean FRF91, Vodafone FRF91. - As always: USE AT YOUR OWN RISK
since I own a Neo V which is locked, and the service menu in the phone says that the Bootloader cannot be unlocked. if I unlock my SIM lock(probably with TurboSIM, since thats the cheapest solution), would that enable me to unlock my bootloader, and start the real modifying of my phone?
i want to know if it's possible to root an Android without unlocking the bootloader. My problem is I don't want anything wiped off the phone. I'm trying to get past the lock screen, because I found this phone in the street, so I want to get the numbers in it to try and return it. I've heard you can bypass the lockscreen if it's rooted. It's a Samsung Galaxy S Mesmerize, (or Fascinate).
I successfully unlocked the bootloader on my xperia x8 via flashtool put on custom kernel nAa 14 and miniCM7 Yay.Everything is fine apart that I want to change network because they have much better deals etc.I went to the 3 network shop and tried to put in the Sim, it took it in loaded but wouldnt register with the network , in fact I tried last week when I was on stock kernel and gingerxperia and it asked for ''unlock code'', today it didn't ask for unlock code took it in but wont register.I guess there must be some sim lock or something.
Maybe it is unlocked but something to do with Radio pehaps nonetheless my current Network works fine.here's my S1 LOG if any good. after unlocking BL of course

I have a problem with my LG optimus 4XHD. I didn't like the 4.1.2 lg skinned android so i wanted to install a custom rom. I started by rooting my phone that worked but then i flashed clockworkmod recovery without unlocking the bootloader. Now i can't enter my recovery anymore but i can still boot into android. Now my question is: Can i still unlock the bootloader now without bricking my phone?
For anyone here that has used Simpleroot, anyone had issues with Step 2? Everytime I click Unlock NAND, instead of moving into that step it does Step 1 again and tries to push the .img to the SD card. Is this a known issue?
The size of the file is much smaller than the size of the stock bootloader, but I don't know if it matters or what exactly I need to flash. I did a lot of web search, including here on XDA, but found no evidence of struggling with flashing the bootloader.
Just ordered an ATT nexus one (getting rid of the pos Samsung Captivate), and I would love to root it and put on a different rom. I have no problem following the guide that is stickied, but I was wondering if z4root (z4root - Android app on AppBrain) works on the n1? I see some appbrain comments saying that it DOES work. Are there different versions of the bootloader and such that it will or will not work on? Also, which modem and kernel do you guys suggest me using (battery life is most important)?
Yesterday I got a sort-of-refurbished Nexus S (I9023) which was apparently not in such a good shape...Had problems flashing the system and userdata partitions (kept saying they were flashed fine but after reboot went back to their previous state).
I followed some tip without actually reading up on it and ended up formatting my bootloader partition.
Now, what I get is just a black screen no response or anything but using a tool called UnBrickable Mod I can get it back to fastboot mode and then boot into a recovery image and have adb access.
All in all, I am currently stuck cuz I want to flash a new bootloader image but what i get when i do that is:
Code: ~ # nandwrite /dev/mtd/mtd0 /bootloader.img Skipping bad block at 0x00000000 Skipping bad block at 0x00040000 Skipping bad block at 0x00080000 Skipping bad block at 0x000c0000 Writing at 0x00100000 Writing at 0x00140000 Writing at 0x00180000 Writing at 0x001c0000 nandwrite: not enough space in MTD device
I have read that NAND blocks tend to go bad when continuously being flashed, but 50% bad blocks on the bootloader partition? Seems pretty unlucky... Is it possible to resize the partitions without any JTAGing or writing custom bootloaders?
I tried the 2.2 root process. short and sweet is downgrade 2.2 to 2.1. Bunch of command line stuff. Install usb drivers, open program to flash and it reboots the phone, then more command line stuff, then installs custom 2.2 and you are now rooted. I got to where I install the custom usb drivers and open the reflash program. All it does is go to the bootloader and sit there. I said screw it and was going to just reinstall 2.2 and be done with the attempt of rooting until a 1 click type came out. Problems is, now I cant even install 2.2. Sits at the bootloader screen. Called Sprint and they tried to help me do a factory reset by going to the phone app and typing ##87# or something.
When I hit reset it was supposed to show a screen thats wiping and reinstalling or something. Nothing happen. Stuck at that bootloader screen again. So here is what I think happened and I need help fixing it. I installed a newer bootloader or older one or something and the new 2.2 is having a hard time getting past it or I just completely screwed it all up. I am currently on 2.1 and all is working fine but I cant upgrade or anything. What are my options and how do I get this back to 2.2? Would love to try and root it and be done. Or just plug it into the PC and reinstall everything back to factory but I am coming from the iPhone where that is possible and I guess you cant on HTC.
So, my issue is that I simply cannot unlock the bootloader of my Nexus S (i9020T). The phone's connecting to my computer via Samsung Android ADB Interface as seen under the Device Manager. I see the proper device ID when I type "fastboot devices" into the adb command prompt. Then, when I type "fastboot oem unlock" the phone starts the unlock verification process -- I select yes, the phone restarts, but it goes back to the stuck Google screen. Then, if I pull the battery and go into fastboot mode directly, bootloader's still locked. I've tried this quite a few times and same result -- same result trying to unlock w/ toolkits like WugFresh's NRT.
I've also tried to solve it w/ all versions of Odin. None of them detect my phone even after installing Kies w/ drivers. I think I have the required drivers though since I can command the phone fine through adb. And Odin should need bootloader unlocked to work anyway so it won't work if bootloader cannot unlock.... I've even tried a few other things like pushing recovery and bootloader images onto the phone via adb, but these also failed due to the locked bootloader. All options seem to require an unlocked bootloader.
I also cannot enable USB debugging under phone settings either b/c I now can't get past the Google logo/fastboot mode menu. I don't think this is required to unlock bootloader through adb though.
Background: Phone had the latest auto updated version of Android when the phone all of a sudden turned off in the middle of the night recently. Weird b/c the battery was basically full. It now always gets stuck on the Google logo upon normal restart. It goes into fastboot mode OK if I remove the battery and press power/vol. buttons -- I then first tried the restore and recovery functions there, etc, but no effect.
To add, one of the first things I tried was to do a manual factory data reset in the recovery menu (selecting 'yes' to erase all data).
And I tried adb sideload of the OTA .zip file. But installation was aborted. The following appeared immediately under the regular adb sideload instruction in the system recovery menu (under "Now send the package you want to apply to the device..."):
Finding update package... Opening update package... Verifying update package... Installing update... file_getprop: failed to stat "/system/build.prop": No such file or directory Installation aborted.
i recently broke my last phone, so i had it replaced and this one is running 2.3.6, i tried using that black white screen (cmd?) with the options ex:
1. unlock root etc.
2. CWM install/root etc etc. x. debugging etc
but no luck. When i reach the rsd lite portion of the first section, my phone just boots up into the os and rsd lite gets cancelled. ( i chose 2.3.4)when i first got it, i could do everything fine, but i couldn't boot after installing 3 different roms. but when i install clean software it works just as it should
Now that the mempodroid hack based on the memory leak discovered by Aedla has been blocked (since about kernel 2.6.42, and android 4.0.3), are there any remaining ways of getting root access without re-flashing the bootloader? Alternatively, any pointers to how I would find (or build) a bootloader for a tablet based on rockchip RK29 board (for which I'm unlikely to be able to get detailed documentation)? Or is there any way to downgrade the kernel without root access?
how to unlock boot loader, root and s-off my HTC one mini. I bought the phone in november so im assuming that i updated to 4.3 or it was already installed (relevant later). I htcdev unlocked my boot loader, installed twrp and made a backup, installed superuser and rooted my phone. Then I installed titanium backup pro, made a backup and uninstalled all the system apps/bloatware I didn't need. All was peachy but the apps kept reappearing which I found was down to s-on (despite what I read about htcdev unlock boot loader method making my phone s-off) . So I tried the revone method and got error 1 which apparently is down to having android 4.3 so I looked for an earlier ROM and flashed Magio r1 which worked fine but couldn't find the data/local/temp folder to install revone into. Probably could of put it somewhere else but I wasn't that confident with the s-off process. So I finally found Jmz m4 stock ROM so there was light at end of tunnel. So I read up on twrp factory reset/format data functions and saw people were using both methods. I went with the full format and factory reset afterwards. Looking back now that was pretty stupid as I have no ROM and no backups to restore to. I did manage to chmod 777 the permissions on my twrp backups and copy the to dropbox (after endless scouring of forums). I also know how to flash boot images and use the adb side load functions. I can't adb push the file as it returns with error closed, I've tried the following commands:
adb device - my device is attached and side loading. adb usb - returns error closed
adb kill-server adb start server - server starts successfully then returns error closed.
And just to be sure I tried with /data/media/, same error..I've fastboot flashed the jmzM4 ROM image and kernel but no joy as I'm guessing the boot image isn't enough and you need the zip. Currently I can load into boot loader and recovery no problem, just freezes on HTC load screen in normal boot up.
I was able to root the device by downgrading it but when i upgrade manually thru flashtool to ics 431,root and superuser app is gone.i also tried Root_with_Restore_by_Bin4ry_v16 but it does not show any restore backup option and nothing happens.. I read each and every related forum searched web but no luck .
