HTC EVO 4G :: Bootloader Screen - No Recovery
Sep 23, 2010
I originally rooted my phone with Unrevoked before Froyo came out(can't recall the version). Once froyo came out, I backed up the phone with clockwork, then flashed over Netarchy's stock rooted froyo(backed up afterwards too). Today I went to the link on the unrevoked twitter page and flashed 3.29 to my phone. I flashed it using the update from SD card option in clockwork. Here's the issue. Afterward my phone rebooted and will not go past the bootloader screen. I'm thinking no biggie, I'll just go back into recovery and load a backup or an older working rom. Well there is no recovery. All I get is the phone with a red triangle. So I'm freaked out and thought, well lets just go back to the stock RUU. Well thats getting an bootloader version error. WHere can I go from here? is there a way for me to get those backups I made loaded from the bootloader screen?

1. Can recovery flash bootloader?
From this link====>[URL] ....., I think it can do that. But I'm not sure.
2. Can recovery flash recovery partition itself?
I think it can not do this. Not confirm that.
3. We know in update.zip, boot.img is corresponding boot partition, but why system is a folder, not system.img? There is a system partition also.
4. While OTA upgrade system, why the update package downloaded under /cache path? Can we change it to sdcard?
5. Most important, what exactly update-script do things under recovery mode? How the command executed?
BTW, there are other questions, but not related to Recovery Mode.
1. How can I see the flash partitions? I know to use the command cat /proc/mtd, but as Samsung, it use emmc flash, while I type that command, no results printed. How to see?
2. About userdata partition, we know that when first run android OS, system will copy files from /system to /data, but does it do it every time that we turn on the phone or just do it once after the first booting after we update our system?

I noticed that you can now add a "Reboot" button to SwitchPro that works a lot like Quick Boot. This is GREAT! and I am super excited. When you press the button, you're given the option for Reboot/Recovery/Bootloader (also awesome!).
The problem is... it doesn't work!
Is this an issue with my Eris/ROM or are other Eris users experiencing the same? If so, I'd be happy to ping the SwitchPro dev to see if a solution can be found.

Have a problem, I cant start the phone i bootloader or recovery. Have done this multiple times before and had no problems then. I have flashed openfire before this, maybe something to do with that?
Really want to be able to make this work, because my battery drains from full to empty in a couple of hours, so wanting to reflash opefire or try cynagonmod to see if that could help my problems.
How do I enable this again? (have tryed to install recovery from rom manager, says success, but cant start in recovery afterall) have clockworkmod 2.5.0.1 now.
Have tested volume down+power, backbutton+power, and restarting the phone in bootloader and recovery, nothing happends.

Can anyone give me some insight on restoring an Eris completely back to stock? I was running 2.1 OTA rooted and I'm trying to get the stock recovery back. I rolled it back to 1.5 using the SD card method, downloaded the OTA 2.1 update but it won't install since the bootloader is S-OFF. Is there an SBF that I should use for this that gives me a total stock flash? I tried to re-root and start over but I wasn't able to get SU installed...I'm all twisted around here and could use a back to basics walk through if one exists.

I have an AT&T SGS4 with a melted USB port so there is no way for me to use fastboot or Odin to flash bootloaders, etc. Is it possible to flash a Samsung factory bootloader through recovery?
What I am trying to accomplish:
I am on Touchwiz 4.3 and the 4.4.2 KK release was leaked in our forum. I used the dsixda kitchen to break it down and made a ROM out of it that successfully flashed in recovery but kernel panics at the AT&T splash boot screen because the RAMdisk doesn't match the bootloader version. So I need to upgrade the bootloader to the 4.4.2 version so it will boot.
I unpacked the RAMdisk and there is nothing in any of the init.xx files that points to the bootloader. I even used a hex editor to look at the init binary which references the bootloader but there was nothing in there that I could change (from what I saw).

I flashed a ROM this morning and it failed. One thing leading to the next I ended up with no OS on my phone and USB Debugging turned off. Now I want to turn on USB Debugging but the only menus I can access from the phone are "Recovery" and "Bootloader." Is there anyway to turn it on or am I screwed. Also, messing with all of these ROMs and rooting my phone so looking for link to a ROM that doesn't make any major changes to your phone. Or the original ROM that came with the phone would be good.

I'm just trying to get my recovery menu back!
I've tried RUUing my phone but that won't work now. It dies on the HTC screen and when I pull the USB I get to a menu that has the option of RUU but it wont' do anything.
So I tried this to fix the bootloader
How-To repair your bootloader after using the 2.1 RUU - Android Forums
It doesn't work
I can't load the flash_image to my system/bin file. My phone IS rooted and I've done it via various ways and none of them will give me permission to move the flash_image to the /system/bin folder
I can't flash a recovery image to flash_image because... flash image doesn't exist.
I'm at th end of my rope and I'm about to slip it around my neck. I know I need to step away from this and take a deep breath, but I'm determined.
Anyone able to give me some hints to as what I'm missing
I'm on 2.2

I've got an HTC One & I've already unlocked the bootloader but had to give the computer I was using up before I could install recovery or SU. SO, is there any possible way to get a recovery onto my One without a computer? Then I can just flash a rooted ROM. I am also still S-ON.

I lose phones... habitually. Sometimes they find their way back to me and sometimes they don't, It is unsettling to me that even if I have a security app installed, or a GPS tracker that ability to perform a google search can simply factory wipe my phone and make it their own.
So the question: Is it possible to include a password requirement to access the bootloader or recovery? I realize that if you forget your password there would likely be no way to save your phone in the event you need to, but I don't forget my passwords so this does not affect me.

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?

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.

Are there other ways to flash a recovery with a locked bootloader?
My Problems:
I can't flash my stock recovery through fastboot with a locked bootloader.
I can't boot into my recovery because my current recovery is TWRP 2.5.0.1 and I have a locked bootloader.
I can't unlock my bootloader because I have used an IMEI Hack Tool and set my IMEI to 0 (I guess).
I can't boot into my ROM because I used an IMEI Hack Tool.
I can't Force Upgrade too (Vol Up + Down + Power). It only shows a pink/purple screen.
Solutions:
I can only flash a recovery with an unlocked bootloader.
I can only boot into a recovery with an unlocked bootloader (except for stock).
I can only unlock bootloader if my IMEI has restored.
I can only restore my IMEI if I can boot into my ROM.
I can only boot into my ROM if I have a stock recovery.
I can only Force Upgrade if I have restored my IMEI.
If I could only restore my IMEI through fastboot,

I see these components discussed all the time on xda-developers. I have a vague understanding of what they are and how they're related to each other, but it's not perfectly clear. For example, the radio seems to be a lot more than just the radio. I have a good understanding of the basic ideas as a Linux user and software developer.To kick things off, let me present my current understanding. I could be way off on some things:"Radio" - I'm not sure if this runs before the bootloader or after HBOOT is the bootloader, the first thing that runs when you boot up your phone. Like your regular Linux bootloader, it lets you boot off of different partitions.There are multiple partitions on the system, at least one for HBOOT (maybe? or is it in some kind of MBR type of area?), recovery, system and data. All of these partitions are in the system's "ROM" which is not really ROM it's actually NVRAM or flash or whatever. Hence, each of these areas can be independently flashed.Recovery is a partition you can boot into. It's originally meant to be a kind of "recovery" mode and so offers a base for hacking. This is typically re-flashed so as to follow further modifications. From the recovery image, you can also access the sdcard which is useful for fetching update.zip files etc. update.zip - these are updates that can be applied from a custom recovery image. It seems like these updates can contain more or less arbitrary code, but I'm not clear on how they get applied or where they get flashed to or applied to./system - gets mounted read-only (what control this?) unless you do some hacking Where does the kernel sit? Is there a different one in the recovery versus the regular image? which parts form a custom ROM like CyanogenMod? What is the NAND and what does it mean to unlock the NAND? What is an RUU? SPL? Where do the WiFi and 3G radio images sit? PC36IMG.zip? PRI?I've seen some of this explained elsewhere but I don't understand how they all fit together.

with sprecovery on my phone. I'm trying to force 2.2 but cannot do it through sprecovery for some reason. RSDlite instructions say I must get to a bootloader screen. I cannot because when I hold power and x it goes into the sprecovery/nandroid back up with the Android guy with a ! on him.

I picked up my phone and it had a weird screen on it that looked like some that I saw when people have rooted their phones (from posts). It had options like "bootloader" and "power down" on it so I used the rocker bar to scroll and get out of it by powering down. My question is this: Someone I know was talking about spyware that can be put on laptops and computers and now this happened when they were around. Is this just a glitch or could it be indicative of spyware having been put on my phone?

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.

So I made the mistake of attempting to root my new HTC one V without knowing what I was doing. I currently can't get past the bootloader screen. I've attempted installing the RUU for my phone with no success. I've resorted to extracting the rom.zip from the RUU, renaming it PK76IMG.zip (required for hboot to recognize it) and putting it on my sd card. Everything works fine up until the end when it says "hboot version is older! Update failed"

This so frustrating. I am trying to root my droid that is currently running the 2.1 firmware. I have researched and it seems that the only way to do so is go back to the 2.0.1 firm. So, I download RSD 4.6, the 32-bit 4.2 usb driver zip, the vzw sbf file, and the apk file. Proceed with everything as instructed and the start button on the RSD Lite stays greyed out. I believe because I do not have the "SE Flash OMAP3430 MI" driver on my PC. Does anyone know how I can get past this? Does this "SE Flash OMAP3430 MI" exist somewhere that I can retrieve it? Is there an easier weay to root or change my 2.1 to froyo 2.2?

I recently rooted my Hero using superoneclick, worked like a charm. I downloaded ROM Manager and was looking to start experimenting with ROMs. For starters, I figured I'd load one of the ROMs already preloaded in ROM Manager (free version).
So I downloaded the ROM which seemed to go fine, clicked on it, followed the prompts which eventually led me to reboot into recovery mode via Clockworkmod to "complete the installation." So I got to the reboot screen, here's what it looked like (below). What do I do from here? Where did the ROM download to? How do I "complete installation." Thanks.
Not sure what to do once I reach this screen. It already asked if I wanted to back up the current ROM and wipe, which I agreed to. when I downloaded the ROM it didn't ask me where I wanted to save it to, when I got to this screen I looked in the SD card by clicking "install zip from SD card" and didn't see it there. Where is it?

I can boot into ClockworkMod Recovery v2.5.0.1 but my backup and nandroid files can't be located. Sometimes I get the Android with the exclamation point, sometimes not. PCIMG36.zip image can't be found either. I think my phone is screwed! I've searched through the forums and googled and tried out a many things but to no avail. Also, does doing all this through a Mac make a difference?

I downloaded the velocity 0.3 and I tried to install the ROM but when it goes to the boot it shows an exclamation mark and the android robot thing. Then it goes away and reboots the system again. Its also the same when I try to access recovery mode via ROM manager. I read somewhere it's the signature for the ROM is missing and to change the settings manually but I can't get to recovery screen.
