Hello everyone, I managed to unlock my phone's bootloader the other day just to end up with the above problem.
Although I've heard that you can loose signal when the line on the s1tool says "NOT RECOGNIZED" whereas in my log ot said "SEMC". Doesn't that mean that it is safe to unlock the bootloader? Then why am I having this problem?
What can I do to fix it?

If you can connect to PCC, then repair your phone! the PCC will will restore your phone to stock ROM. Then you use Stool to "re-lock" your phone again.
If you can't connect via PCC, then do the following:-
1) Download a stock rom,
2) Use Flashtool to flash your phone with the stock ROM you downloaded
3) Use Stool to "re-lock" your phone again.
4) Re-boot and you should be getting your signal back by now!
5) Re unlock your bootloader again, should be OK.
Please don't mess the steps in sequences, if you re-lock your phone"not in stock rom" will break your phone.
Yeah, everything is working fine except the signal problem.
Another thing (might be completely irrelevant).
I flashed GDX v022 without flashing the addons package. Does that have anything inside that controls the signal or something? (highly doubt it)
I followed this guide everything worked for me. Look at this guide and see if you missed anything or did something wrong.

No, if you flash GDX (on Stock Kernel) without the Stock Kernel Modules AddOn you just won't get: ax8smartass.ko, ax8mt.ko, ext3.ko, ext4.ko, jdb.ko, jbd2.ko, x8gesture.ko, x8mddi.ko and x8uv.ko
There's not a single file having to do with GSM/2G/3G radio, so it's, as you already put it, completely irrelevant.
So were you able to restore your phone?

Thanks for the guide. I think I mistakenly executed "msm7227_Setool2.cmd" instead of "msm7227_semc.cmd".
Getting ready to restore original firmware with SEUS and later relock the bootloader
Can anybody tell me in what order should I root, unlock BL, install custom ROM and then a custom Kernel?

you should: root, unlock BL, flash kernel, when phone restarts enter cwm by back button, now flash rom
btw I suggest u to try MiniCM, its so smooth.
Another thing...(sorry for so many questions )
I managed to unlock BL and GSM is working fine. Thanks everyone.
Before all this, I made a backup of GDX in CWM. In another tutorial I read that you should remove everything inside the modules folder before attempting to install a custom kernel. The thing is that GDX already has some files there. Is it safe if I flash the kernel and then restore the ROM I backed up?
I flashed alfs kernel and..I don't see speed improvement...actually it's worse...maybe I shouldn't have deleted all the files in modules folder. Is that the cause of the lagginess?
If look into my other post from above I listed what modules the Stock Kernel Add-On contains - you only need to weed out that ones.
MDDI (aka "lag fix"), ext3/4, (fake) dual-touch, et al should come per default as a integral part of the custom kernel (i.e. Alfs).
Just look into the GDX ROM ZIP and copy the default files from the ZIP to your SD, into the modules folder, set permissions, reboot ... or simply re-flash the GDX ZIP.

Hi,
I've been searching the forums for this, but haven't found any real answer, so I thought I'd open a new thread .
I've successfully rooted my stock N1. However I'm wondering, with my newly acquired root rights, would it be possible to flash a custom kernel on it without needing to use a custom ROM.
The reason I'm asking this is that I would like to use iptables for use with a transparant proxy. It seems that the stock kernel does not support this
Of course if anyone has a different approach for the proxy, feel free to let me know as well .
Thanks!
I was able to flash just the cyanogen kernel onto my FRF91.
Sent from my Nexus One using XDA App
instructions?
Ok that is great news... did you encounter problems afterwards with any of the core components? what about some instructions on how to do this (or a link )
Thanks!
I haven't seen any problems with the stock components on the phone.
I can't find the thread I got this from to save my life! I don't know where you are in the process so here's the entire list of what I did:
Unlocked the bootloader using the fastbooot oem unlock command.
Flash Amon-Ra recovery for N1.
Reboot straight into recovery, Back up Stock ROM.
Flash Modaco's superboot for FRF91 from recovery
Flash Cyanogen's N1 Addons (which contains the kernel).
If you google update-nexusone-FRF91-cm-addons-signed.zip you'll see a bunch of downloads for the kernel update. The MD5 sum on the file I have is: 7cf8074d3685681728043f367e6b35fd
It goes without saying, but backup your phone before flashing...
Thanks
I actually rooted without unlocking the bootloader, and would prefer to keep it that way since I get to keep my warranty
I'll try this today, thanks a lot!
Tried it, failed
No worries though, just 'upgraded' to CM6 RC2
Hi,
It is possible to reinstall android (official rom) without loosing warranty? There are an option in LG mobile to do that?
I want to something to fall back on if something went wrong (and I dont mean making a hard reset).

Better use this method if you want 100% original factory ROM:
http://forum.xda-developers.com/showpost.php?p=15039107&postcount=16
Thanks everyone!
One other question, if I do that, the phone will be unrooted? And if I flash the phone with a custom rom, this will make my LG like out of the box and I wont have any problem with the warranty?
Thanks
not with a "custom rom" but a "Official rom" !!
If you reflsah an official rom, you won't have any problems with warranty.
Hi,
I think I didn't explain myselft.
My question is this:
I want to flash a custom rom. I use Rom Manager, install a recovery image and install a custom rom. so far so good.
But if I have a problem with my phone and I have to use the warranty. This way I loose the warranty.
But if I flash the official ROM, when I send the phone to the warranty, they can tell if I flashed a phone with a differente rom, if I rooted it? If I flash it will erase the recovery image, the root,everything? And I will not have any problem?
Thanks
As i wrote before, use THIS method. After this you'll have ORIGINAL STOCK ROM which was in your phone after unboxing. There will be no sign of rooting, custom ROM, etc.
as I already said, if you flash Official rom of you region (or operator) (with method 1 or method 2, no matter) you'll have no problem with warrenty

Hello guys,
I've been looking around hier for a while, and I spotted a Custom ROM that I'd like to try, it's this one: http://forum.xda-developers.com/showthread.php?t=1424260
I've never rooted my phone before so I don't have experience with it.
I found a couple of threads that can help me but, I don't know in wich order I have to follow them.
First of all, I'd like to make a complete back-up of my current ROM, so in case something goes wrong, I can restore it. How do I do this? I read something about ClockWorkMod and a nandroid back-up, can somebody clear this out?
I have an unrooted HTC Incredible S with S-ON. So first, I think that I have to get S-OFF? I found a tutorial with the Revolutionary tool, but it doesn't support my HBoot, so I think that's not an option?
So then, I found this tutorial: http://forum.xda-developers.com/showthread.php?t=1337105
The tutorial is easy to follow, but can I create a full back-up before I start the tutorial?
And to get S-OFF, do I need a rooted device?
I hope somebody can help me. If you need more information, just ask.
Here is some information about my device:
- Android 2.3.5
- HTC Sense 3.0
- S-ON
- Not rooted
- HBoot 2.00.0000
- No SIM-lock
If more information is needed, please ask.
Unfortunately having your current h-boot the method available to you to root and install custom ROMs does not let you back up your phone prior to flashing. As the method used is flashing a new ROM that allows root access to your phone. Prior H-boots (1.13.0000) allowed you to root your phone without flashing a custom ROM thus unlocking boot loader to be flashed CWM as a custom recovery and allowing you to create a nandroid backup of your current state before flashing a new rom. However[/] the process you are going to need to complete might contain a back-up function included in the flashing process, I don't know for sure as I flashed from 1.13.0000, but it doesn't really matter as your going to have to complete the process anyways. I say just go for it and follow the instructions to the "T". If you follow everything properly and take your time you shouldn't encounter any problems.
In the tutorial I posted, step 10 is
10. Using volume up/down and power to select, go down to Backup/Restore. Select it, then hit Backup. ClockWorkMod will backup your stock ROM in case there are any dramas and you want to go back to it.

Will this create a complete back-up? So when I restore it, will everything be back the way it is right now?

Exactly. Stay safe.
So if I just follow that tutorial, I will have a Custom ROM with root? And do I still have to get S-OFF?
You don't need to go S-OFF to flash a custom rom. There is actually no need whatsoever to go S-OFF, unless you want to go and flashing other radios. But the lastest sense 3.0 and android 2.3.5 update included the lastest radio, so keep S-ON. Better for warranty.
First go to htcdev.com and follow the instructions to unlock bootloader. BE AWARE THAT THIS WILL WIPE YOUR PHONE TO FACTORY DEFAULTS for security reasons, sdcard remains untouched.
After bootloader unlocked you can flash the clockwork recovery (you're still S-ON). Once you flashed that you can go into recovery with volumebutton down and power on. Take a backup with clockwork (=nandroid = full image of the phone in its current state) of your original rom and start flashing custom ones.
They're is probably a time where you gonna think you bricked your phone, I have. But I always got through it by searching the forum. Always, in any circomstance, manually push the boot.img of the associated rom from a PC to your phone. So never flash a ROM from your sdcard if you don't have a PC in hand. Otherwise it will probably not boot or get hardware not working (not broken in anyway, just not properly loaded).
Before changing roms, I always do the ARHD wipe script. Just to be sure every trace of the previous rom is gone. There are multiple partitions on your phone (system, data, boot). It wipes all of them to start clean.
The ROMs you are going to flash are rooted by default.
So now, of you go and be a ICS beta tester
Thanks fot the explenation.
But, because I can't root my phone because it's HBoot 2.00.0000; I can't make a back-up of it? Not even with Titanium Back-up.
Is there any way I can back-up my app's? So I don't lose all the saved data in the app's?

As far as I know the answer is "no".
You need clockwork for a nandroidbackup, you need bootloader unlocked for clockwork, unlocking bootloader wipes your phone.
I accidently wipe mine with the unlocking of the bootloader. It seems harder than it is to start over. Just link contacts and calendar with gmail, backup sms on sdcard in messaging. That's all you need. Starting over is good to get the crappy apps gone
Hmm, okay, then I'll have to do it without making a back-up.
And is there an easy way to switch between ROM's? Without using a computer.

It is very easy to change roms. They are stored in zip-format on your sdcard which you can browse to with clockwork. Also the nandroidbackups are stored on your sdcard and can also be chosen with clockwork.
Experience tells me that you still need to flash the boot.img of the rom manually after you flashed the rom (something to do with clockwork not able to write in boot partition while in recovery-mode, you have to be in fastboot-mode). Flashing the boot.img litterly takes 2 secs to upload, done, and reboot.
So it is no big deal to swich:
- boot in recovery
- browse to the desired rom/backup
- start and wait 5 mins
- boot in fastboot
- connect to pc and flash boot.img
- wait 2 secs and reboot
Do not flash when you need the phone and there is no pc around. If it goes wrong, you need your usb pc to fix things.
I heard something about Rommanager, can I use this and what does it do excactly?

ROM Manager is an app that works with ClockworkMod recovery to keep it up to date and allows you to make and manage CWM nandroid backups and manage partitions on your SD card. The paid version also allows you to download custom ROMs and flash them.
It requires root access in order to run.
But it's not a necessary application?

Thanks for everything who helped me, I followed the tutorial and everything is working fine.
Hi, i rooted my Z1 on Monday and a few questions pop up, so what did i do:
i had 4.4.2, so i downgraded, then rooted, then installed dualrecovery, then using CWM i flashed [Nut]'s .681 FTF and saw i got superSU and stuff, checked for root and i seem to have root. phone seems to be working fine.
Q1: What is the stripped FTF for? i flashed the corresponding stripped FTF later, also from [Nut], but it kinda broke things, and i started to experience strange things like vibration&sound gone, gyroscope not working, etc. so i flashed [Nut]'s .681 back but without the stripped FTF - works fine this way and i got root. In my research i found that the stripped FTF supposedly only contains a kernel. is that true? what is different in that kernel? do i need it or can i keep the kernel that comes with the .681 ROM?
Q2: Today i found out a new version came out the .757. i purchased Titanium backup, and made backups of my third party apps and data. i also made a TWRP backup, and i am considering flashing the new .757 ROM. But i would like to know if there is a way to save my email settings, i mean not the emails or sms itself, don't care about that, but the email accounts and its settings like pop, smtp, email, exchange email, etc
because everytime i flash a new rom on my z1, i need to setup like 6 email accounts and its getting annoying. so Q2 is: is there a good way to backup those?
Q3: do i need a stripped .757 ftf?
Q4: for third party apps to have write access to my sd card, i had to install a fix for the permission.xml in .681 because google supposedly changed the required permissions, do i have to fix it in .757 too? if yes, can i use the same installer? afaik it's just adding a few lines in permission.xml, then setting the proper owner(root root) and attributes (644 was it?), so theoretically if all that installer does is replace that one file it should work right?
Q5: i purchased setCPU Pro to find out it can't set the governor and frequencies on the other cores, just on the first one. so i tried a few others and use "Multicore CPU Control Free" now, it says the free version only lets me set stuff on the first core, but it seems like i can also set the other cores and also the settings seem to work. so i am kinda satisfied, but is there a better one?
Thanks for reading and answering in advance! i am quite new to this rooting and unlocking and flashing thing....:
You need to follow the instructions in the OP of the rom.
You have not done that, that's why you are hitting problems.
Flash the .zip and then WITHOUT REBOOTING the phone flash the stripped FTF, and yes, you do need it
oh, i see, yes i did indeed boot into the rom before flashing the stripped FTF. still without the stripped FTF it seems to work fine, i have root and can run all apps requiring root.
So what exactly is the stripped FTF for?

Basicaly it installs the correct kernel without flashing user data, apps or system
The kernel has probably not changed between 681 and 757 so it will probably work without flashing that if you are coming from 681.
i see, thanks, so is there a way to keep all my settings and flash to newest version .757?

yes. if you are on 681 now just follow the instructions in the OP
wow i just flashed .757 and really didn't lose my data. i thought when i flash a another Rom it always deletes everything? Thanks!
this time i also understood correctly that after flashing 757 i had to turn off and immediatly flash the ftf. looks like no problem so far. Thanks for explaining that too!

Hello, i'm newbie here, trying to learn some stuff, i searched the forum but i couldn't find it, i think this page is most appropriate to post it here.
Well i want to flash a custom rom, but my first attempt went not good for me. I've lost my imei and panicked, anyway by flashing stock sony rom i recovered it.
Now i unlocked my bootloader again (it was locked again after i flashed my stock firmware back), rooted my phone, and learned that nandroid app can make a full backup, and even i screw things up (except hard bricking i guess), that backup will save me. So i downloaded it made a full back up, but it says "back up type: clockwork or TWRP,"
And i heard that TWRP is not for Xperia Z1. Thats why i decided to not install it,
Then i installed clockwork rom manager, it said "this app requires clocwork recovery", but i couldnt find a appropriate version of clockwork recovery, the ones i found on play store were for android 4.0.4, and mine is 4.4.4
You guys probably understand that i know almost nothing about this stuff, (i have only got what i read form forums), so what should i do, which version of clockwork should i install or is there any other supported apps that i can use my nandroid backup?
Soka, i checked your link but couldnt be sure about which link should i click.
And another question, do i still need titanium backup while i have nandroid?
Thanks in advance

CWM Recovery
There two methods:
1. Unlock your bootloader and flash a custom kernel (Bootloader Unlock is required for flashing custom roms which are not stock based; for example cyanogenmod)
-> with a custom kernel you have cwm and often twrp also.
2. check this out: http://forum.xda-developers.com/xperia-z1/development/newroot-z1-t2807092
maybe you have to flash .108 kernel to use newroot, after rooting you can flash the actually kernel from your firmware....
