You only need to have CWM and the CWM flashable zip. Then, just boot into Recovery, select Zip from SDcard, pick your kernel, flash, enjoy.

No I meant if I flash a kernel immediately after flashing rom or do I wait for setup and then reboot into recovery and flash

Ah I see. Well, I don't know if it's required, but I always flash a ROM, let it boot into the system, wait for about 30 minutes, then go back and flash a different kernel, just to be safe.

Hmm. Phone only seems to like one rom

So I recently flashed to aospish_jk2_v1.0. Works just fine. But I wanna goof around with some other roms. But when I try to flash to other roms or my previous stock backup, it goes into the recovery flashing screen for about 2 seconds. Then the phone restarts and I'm in recovery. When I reboot the phone I'm still on the same rom..what should I do? Try to use odin to flash another rom?

are you flashing though the clock work recovery? Is the recovery letters blue or green?
I've found the best way to go between roms is always Odin back to stock, then install the new rom. That seems to prevent most problems.

I used rom manager to flash. But when in recovery letters are blue and it says android system recovery. So I'm assuming clockwork recovery actually hasn't installed?

You need to open rom manager and flash the CW recovery... from rom manager then click on flash to CWR... it will take you to stock recovery, click on reinstall packages.
now you are at CWR and can flash new rom.
Ah. My problem was that I never flashed ce recovery properly. Thanks guys.

ROM Flashing and Kernel Flashing; Order of Operation?

Hey guys, I've been flashing roms and kernals for a little while now and still I'm far from an expert. I've managed to brick my phone recover and do many other things from the help of this forums and I thank you. But I guess I never knew the answer to the following question.
Is it better to flash a rom then flash the kernel (Overstock, tigersblood etc) before loading the rom and waiting 10 mins or is it better to flash the rom, then load the rom wait ten mins or so then go back into CWM and flash the kernel and wait another 10 mins?
What makes for a more stable rom?
I always flash the rom, do a reboot recovery, flash the kernel then let the phone boot into android. Haven't had any issues.

Flashing kernel first is dumb, because doesn't flashing the ROM replace the kernel????
Obviously.
1) Flash rom
2) any kernel if any at all
3) factory reset (depends on rom)
4) reboot
5) wait 10 minutes, and reboot and done.
I think he meant flash rom then flash kernel immediately or let rom boot, wait 10 then flash kernel...

You CAN flash the rom and then immediately do the kernel, BUT
I believe it is preferred/better to do the rom... let it sit for 10 minutes... reboot.... restore all your apps, reboot into recovery, flash the kernel, rejoice.
That is my preferred method.
Lol, this is a funny thread. But heres what i do.
- Flash ROM
- Boot (Let sit 15min) play blackops here
- Power off phone
- Power on phone
- Reboot recovery
- Flash kernel (usually OC)
- Restore setcpu
- OC system and begin restore process of titanium, sms, bookmarks and such.
Only reason i do this is personally i like to restore with the system OC but thats just me.

Do you lose all settings/media on phone when flashing kernels like you do when you flash ROMs?
No you don't

Can't boot into CWM even though rooted

I've installed CWM. However, whenever I to boot into recovery it'll take me the "Android system recovery <3e>" with no option to install from SD, therefore I can't install any ROM. What can I do? Please help.
If you have CWM installed, when you go to the stock recovery, click on reinstall packages. It will reboot into stock recovery again and again click reinstall packages, and it should take you to the green CWM recovery.

He has 3e recovery and that won't work.
Op: Odin a voodoo kernel, as it's the easiest way and has cwm built in. The other two methods include ironing to jfd and flashing custom rom (easiest if custom is your end goal) or replacing 3e recovery with a modified one (hardest method by far).

Flashimage.gui app

I don't have my computer now and want to update miui tonight. Is the steps of using this app
1. Select recovery image
2. Chose the new rom
3. Wipe dalvik and cache
4. Hit ok
Is there anything else that is needed to do? I can't afford to mess up my phone since I don't have my computer now. Any help would be very helpful. Thanks.

You dont need a PC if you are s-off.You are on hboot 1.50 I think
In another thread joeykrim (developer of Flash Image GUI) told that there should not be any problem untill a rom and kernel mismatches.
So i think you are good to go with that app.
But imo the steps are:
Run Flash img GUI
Choose kernel
then tap browse and selecet the zip file of miui rom
It should give a message to make sure it is a valid rom zip as the file size is much more.
Then tap flash image . the app will flash the boot.img from the romzip file.
Then it will ask to reboot.
But i think you should not reboot the phone as you are flashing a aosp kernel.
You should power off the phone.
Then boot into bootloader >Go to recovery > Then install the miui rom zip file from recovery.
Hope this helps......
Dont forget to thanks if I helped you.....

As far as I know, support was added for selecting the kernel image from the ROM zip itself. So select the image, wipe dalvik and cache, ok, reboot and flash the ROM.
So select kernel image in the app. Pick the miui and wipe dalvik and cache then hit yes and that's it? I'm alittle confused cause I don't want to f it up. Don't choose recovery image to do it choose kernel?

Yes exactly......choose kernel image in app not recovery.......then choose miui rom's zip file > then boot in bootloader > go to recovery > install zip from sd card > choose from sd card > then select the same zip that you have chosen in the app (miui rom.zip) . If you choose recoverey and then selct miui rom .zip you may really f it up
If something goes wrong then you will need a pc to solve the issue......

I did that. It's all good but when I boot into recovery it just restarts. Is there something I'm missing?

are you able to boot into bootloader? you need to uncheck fastboot from settings>power or you can turn off the phone and remove and reinsert the battery then hold volume down+power button.
If recovery is not working try to flash a zip file containg a workig recovery with flash image gui.

I downloaded the recovery from the website I got the app from and flashed it through the app and it said successful. When I boot into recovery the htc logo comes up and after a minute it just reboots. Do you have a better link for me for recovery?
Sent from my PG86100 using xda premium
The only Recovery that worked for me is in the attachment.
It contains the recovery that i use. Extract the file using any file explorer then you will have a cwm.img . I dont know if you can flash a .img file with Flash image GUI. And dont forget to select recovery image option in the app while flashing this.
I've been trying to get into recovery and It won't work. I followed all of your guys suggestions and still nothing. I downloaded the cwm file from the website and selected it and it said successful but when I try to restart and boot into recovery it stays on the htc screen for a second then vibrates and then just restarts. Anyone have a clue what I'm doing wrong?

Different App related question:
I'm running CM7.1 right now. I would like you use my backed up version of MIUI that I backed up using TWRP. Can I boot into bootloader using FlashImage app and go into recovery and do it? Or do I still need to go into bootloader using a computer?
Many thanks.

That's what I'm trying to figure out
Sent from my PG86100 using xda premium
Well if you're getting the bootloop then I'm guessing it's not possible. Because while it's rebooting, you're holding down right?
If so, then I guess that answers our question. It's not possible.
Need to go into bootloader the normal way using a computer.
So I'm assuming that this app is really only for flashing kernels. I tried that and it worked perfectly.

Hey thats not true.....I was on olymus ROM and i wanted to switch to infected ROM but i wasn not having PC but my recovery was working . I used Flash image GUI > kernel image> Selected the infected ROM> And it flashed the boot.img from infected ROM .zip
Then I rebooted in bootloader > selected recovery > install zip from sd card> and chose the same infected rom.zip......................and everything worked fine.
@arozer
If you want to restore your backed up MIUI then I think you will need to flash the boot.img from your backup 1st using flash image GUI. Then without rebooting phone , you have to boot into recovery then restore the backup.
@peecs121
I guess you will need a computer to get your recovery working using fastboot.
Maybe you should do that on your friends PC .
Then try the steps.
I will download the latest MIUI and will try to install it without a PC for you.

hey I downloaded the MIUI ROM and flashed it successfully without using PC.
For you I also tried Flashing different recovery through Flash Image GUI which also worked.
Here's what I did:
1.copied the " MIUI.us_shooter_1.12.2_Eng_Deo_ZipA_Signed_scott951.zip "(97 mb size) and recovery.img to root of SD card
2.In Flash Image GUI , I selected recovery image option and flashed the recovery.img by using flash image button ( also checked wipe dalvik & wipe cache) Then it prompted to reboot and i tapped no
3.Then i selected kernel image in Flash Image GUI and Selected the "MIUI.us_shooter_1.12.2_Eng_Deo_ZipA_Signed_scott951.zip" and flashed it aslo using flashimage button( also checked wipe dalvik & wipe cache)Then it prompted to reboot and i tapped no.
4.Then i switched off my phone manually.
5.Then i booted into bootloader by pressing volume down+power button..
6.selected Recovery and pressed power button and recovery booted successfully.
7.In wipe menu i selected wipe cache , wipe everything ,dalvik etc
8.Then pressed go back and selected flash zip from sd card and select Synergy_3Dvo_Superwipe.zip
9.Then again flash zip from sd card and select Synergy_Format_Data_EXT4_Optimized.zip.
10.Then again flash image from sd card and select MIUI.us_shooter_1.12.2_Eng_Deo_ZipA_Signed_scott951.zip.
11.Finally reboot the phone and voila!! got it to workwithout PC.
You could flash any other rom instead of MIUI.
And i wanna ask you have you even unlocked and rooted your phone?
Here are the files you will need:
The recovery.img is here http://www.mediafire.com/?n72emuv5a1c00sd
Thank you so much man for those steps!!! It worked perfect!!!!

How do I boot into recovery without rebooting?
Also, in my back up of Miui in the Twrp folder, I don't have file called boot.img. i have boot.win and boot.win.md5
Would one of those be it?
(I also have data.win and system.win.)

Oops!! Sorry
I wanted to say that after flashing boot.img you should not "normal reboot" the phone.
You should power it off and boot in bootloader > recovery..
Sorry for the mistake
Which version of which recovery do you use.....???
The CWM 4.0.1.4 recovery by revolutionary (which i was using till today) made ".img's" in nandroid backup. I dont know about your recovery.
If you had not changed your kernel while you were using MIUI
You should do one thing:
1.Instead of searching boot.img in nandroid backup, just use the boot.img from the miui rom's zip file you downloaded and flash it via FLASH IMAGE GUI and follow the above steps by me from step 3 (if your recovery does not work, follow steps from no 1). You will be good to go.

[Q] flash image question

hey everyone. so my question is about the flash image gui. if I flash a kernel through it and reboot recovery, am I able to wipe the rom using superwipe right then and there? or do I have to reboot recovery again to make the kernel stick so superwipe doesn't touch it before flashing the rom. pretty sure that's clear. but if not let me know. thanks for everyone who looks and helps!
When using flash image GUI to flash a kernel. You don't need to go into recovery at all afterwards. Should be good. When installing a ROM with a custom kernel flash superwipe script then flash ROM in recovery boot phone then flash kernel VIA image GUI. Then test your wifi, 4g, data, calling etc.
sent from America...F__k Yeah!
Actually you had it right the first time. You flash the kernel first, reboot into recovery, wipe then flash the rom. Wiping won't touch the kernel you just flashed.

You should change this post as you could cause problems for people. If someone is changing from sense rom to an AOSP rom, or vise versa, you definitely want to flash kernel first with flash image gui.

Because of s-on I don't think that the superwipe script can affect the boot partition of the phone so your good with what you say OP.

Oh! Thats weird because thats how I have been doing it. Everything works for me. I been on just about all ROMS out there...from ICS to sense 3.5 and now the lastest firmware running imbredded ROM. Only once I had a problem with a kernel when I updated to latest OTA using my method above. I then used flash image gui to flash the stock kernel (boot.img) and everything worked fine after.
thanks everyone for answering! I was pretty sure the superwipe wasnt able to erase the kernel being 1.5, just wanted to have some clarification
