General :: Can Recovery Flash Bootloader?
Jan 28, 2014
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 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).

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,

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?

I rooted my S3 a few months ago based on some detailed instructions found online - no issues. The method used involved clockwork mod or some such.I was following these URL....
instructions to attempt to install liquid smooth (URL...) ROM. I had backed up everything on titanium backup and using the back up in ROM manager. In step 3.1, "flash a recovery image," I didn't think I needed to do this, as I thought it was a part of ROM manager.I proceeded onward, and after the phone finished making a back up, immediately after it started to install the new ROM, the screen went black (I assume the phone turned off).
I'm currently unable to get it to turn on at all, taking the battery out didn't do anything, and when I plug it into the comp via USB, it doesn't seem to recognize the device.I'm a broke med student on loans, and a new phone is going to hurt the bank account a lot.

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'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.

I have a phone called Y9190 that suddenly turned off and will not turn back on. I tried to flash it with flashtool, but the program sends me this error:
"Boot Loader does not exist on NAND / eMMC flash! Please download bootloader first."
At this point, I do not know how to go forward. The flashtool drivers are installed correctly and the rom is the right one.

My android is rooted and sim-unlocked by Omnius.
I manually installed ClockworkMod Recovery. (to do this I had to remount the /system folder as rw, don't know if this is important, but wasn't in the installation instructions).
PC companion says my firmware is the lastest
I want flash this kernel. I think I can't unlock my bootloader...
I followed this guide to unlock the bootloader, using FlashTool or msm7227_omniusSL.cmd. Both processes complete without errors... But when I check with s1tool, the erom version has an uppercase "R".
When I try to flash, FlashTool throws the error:
Code:
06/056/2012 20:56:22 - ERROR - ERR_SEVERITY="MAJOR";ERR_CLASS="SECURITY_CLASS";ERR_DYNAMIC="SIN header verification failed"
Here are my s1tool and FlashTool logs:
s1tool:
Code:
Welcome to S1 identify tool
[Code] .......
Both BL unlocking methods were repeted several times, with equal logs...

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?

I have a Nabi 2 tablet that I've rooted, installed TWRP, and flash the gapps and a few other tweaks to. It's about to go in for an RMA since the USB and charging ports are both broken. The problem in the USB port is that one of the pins got bent - I don't know how, it looks like the conductor somehow got peeled back off of the plastic. The point is, I have no USB access to the device.
In order to pass the inspection for the RMA, I need to have it stock I can flash the stock ROM by putting it on the SDCard in my laptop then transferring that to the device and flashing it through TWRP. The question I have, though, is whether I can flash the stock recovery with ADB access to it. Every thread I've been able to uncover so far about flashing a recovery requires ADB access to issue the "adb fastboot flash" command. Is there another way to do this?

I have myTab 7 tablet and it's not officially supported device for any recovery. Does it matter? Can I flash any custom recovery e.g. CWM touch recovery or TWRP? Won't it destroy my tablet?

I hit the top button. Flash Clockworkmod recovery or what ever it said. I then backed up my Current ROM. I then downloaded Cyanogen v6.0.0 cr2. It downloaded and rebooted my phone. But It went to a screen with a Triangle w/ exclamation and a phone under it. I then hit the up vol button and camera, and now I'm at the Android system recovery page and I don't know what to do next. These are my options reboot system now apply sdcard:update.zip wipe data/factory rest wipe cache partition wipe base band data. I did click to backup current ROM and wipe data and cache.

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.
