HTC EVO 4G :: 2.2 To 2.1 And Root - Now Stuck At Bootloader
Aug 30, 2010
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.

I have tried multiple things, but I'm still stuck at the boot loading screen with the X.
I had cyan 5.0.4. - I wiped and flashed to 5.0.5 and now i cannot get past the boot.
I've tried booting back into recovery and wiping and doing a nandroid recovery to 'amon's recovery 1.7.0' but to no avail.

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.
adp push rom.zip /data/media/0 - 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 want to install Cyanogen 11 in my xperia sp, but we have to unlock the bootloader first unlocking bootloader will result in permanent loss of Bravia engine 2.
But we can backup the Bravia engine 2 by backing up TA, but for backing the TA we need to root the phone, for rooting the phone we need to unlock the bootloader.

My phone wont boot into android because of a bad setting I made in pimp my rom, it only boots into recovery now. So what I need to do is sort files modified by a certain date and time (last night) and restore them with originals hoepfully to get my phone to boot back up.
So how do I navigate and search my root directory through 4ext recovery or bootloader, because those are my only options?
Is there a way to mount these directories and browse them through windows as if it were an actual folder so I can use windows 7's build in search features as well? I have android commander installed and can use that if need be.
how to exactly approach this without installing my rom back over again.

I have a One V, and I want to backup atleast 30 wifi passwords I have stored on my device, but all the apps on play store require root.I can't do that as unlocking the bootloader will remove my phone data, so I'm asking :
If I unlock the bootloader and then restore data still with the stock ROM on, will it restore the wifi data automatically, and then hopefully I can back it up with a wifi backup app (cause there is no way to root device without unlocking the bootloader atm)?Here's what dashboard is showing as backed up:

I have rooted my phone and have now the recovery mode from HD blog. It's was working fine. So I tried to get the Galaxhero ROM installed. I did the following steps:
1) Reboot in recovery mode (Volume down + both Call buttons) and choose "Nandroid backup" to save a backup of your current ROM just in case.
2) Backup G apps
3) Then, choose "Wipe data/factory reset". The phone will reboot in recovery mode again.
4) Choose "Apply sdcard:update.zip" (second menu entry on the recovery screen)
5) Restore Google applications ("Restore G.Apps")
6) "Enable root (su)".
But then enable root failed! Anyway I went on further with reboot system. It rebooted till the "android HD logo" showed up and then suddenly the screen went off and it seemed like my phone went off. So I went back to the recovery mode and did the following steps:
Wipe data
Restore backup
Restore G apps
Enable root SU, but again enable su failed!!
Again I choose reboot system, and when the reboot came again to the "android HD logo". It stuck there and stayed looping.
First, why do I still see the android HD logo again because I did a wipe!
Second, How can I get my phone working again!

I had a rooted Incredible using this method before however I had a problem with the on screen keyboard so I got a replacement. The replacement just came yesterday. Now I am rooting the replacement and the Unrevoked 3 program gets stuck at "Waiting for root... (Safe to restart if this doesn't work)"
I have the HBOOT drivers installed and my phone comes up in device manager as "Android Composite ADB Interface"
Did they apply a new update to the phone that prevents rooting? If so how long before I can get around it?

My dev phone has a stock bootloader. while upgrading to the official signed-dream_devphone-img-147201.zip image I suddenly received the message a ota update arrived and i accepted it. How wrong i was! Now i have a phone with the bootloader with hboot-0.95.0000 in stead of the 0.95.3000. Strange thing is it still has the test keys. Is there any way to correct this? I see guides for rooting your standard G1 everywhere but i expect that i can't install these images due to the test keys on my device.

I am trying to root my Droid but everytime I hold power and up on dpad it just gets stuck on a black screen. I can tell it is trying to go to the bootloader but it just doesn't go. Do I need to hold the power button while holding the dpad up? I need to know because I dropped my phone in some water a few weeks ago and it screwed my power/sleep button up a little bit.Sorry this question may be such a cluster but I'm just trying to get some tips or information on what to do.
