Officially desperate. Please help. Will pay in form of just about anything.

Hi all,
Here is my sad saga.
Today, I decided I wanted to move up to ICS. I had 2.3.4 on a Koodoo phone that I decided was ready for the brave new world of ICS (bought it off Kijiji, now running it on Rogers which means I have no option of bringing it into a shop).
Ran into some issues but some good folks saved my butt in a number of tough spots. However, my grave seems to have been dug deeper by the minute. Essentially, I have managed to upgrade to 4.0.3. but am stuck with no 3G connection, hence no phone signal. This is a HUGE issue since I require my phone for work (foolish move #1 of the night).
Here are things I have tried and the challenges I have faced thus far:
1) CWM. Have not been able to access it or install it successfully. However have somehow managed to root the device. I did it through a one-click root/CWM tool I found online but have never been able to access CWM from the recovery screen, only stock recovery.
2) Changing the radio baseband version. Fail, since I have no CWM. Or Root Explorer because...
3) I can't access the google Market as I have no data connection. And did I mention no wireless? I live out in a rural area (sad story #1). It's ethernet only, sadly
4) Also, I have very limited access to a PC. I do have one at work, but I have my own macbook. Although I could use the PC at work to try some stuff out, I can't be spending my entire day Googling for help. Seems like employers would frown greatly on it. I've already spent a solid 4 hours on the forums and Internet tonight trying to find something that works. Absolutely no dice.
5) Attempted to get back to 2.3.6. No joy. Phone won't budge from 4.0.3. and I think it has to do a huge part with no CWM.
6) Factory reset a number of times. Still stuck on 4.0.3. with no 3G connection.
7) Reset APNs to default. Still no luck. Perhaps it isn't the radio baseband after all?
8) Also tried entering and leaving airplane mode a number of times. Zero luck.
9) I have a pretty low comfort level with PCs to be honest. I am open to all instructions, as long as they are detailed and written For Dummies.
Please help. I really, truly do not know what else to do or where else to turn but the forums. I've tried everything I could think of and I'm afraid this will impact my job since I need to be in constant phone contact for work. I'm exhausted from stress and worry. I swear this will be the last time I experiment with my phone (I know I've said it before, but this time I MEAN it!)
Thank you all you kind-hearted folk out there for anything you can do to help.

first cell phone model you have and that you had changed baseband before all ... You can also try a new version of CMW in case, can also be kernel problem that uses TO in the mobile ...

So you have a nexus with barely PC access running ics minus a recovery. Good news is your in luck. You need proper tools to do the job. Easiest method is either on that Mac or at work, install the phones drivers. search Google for the fastboot binary for the operating system your using. Once the drivers are installed boot to fast boot not recovery but the screen where you choose recovery. Open a terminal on the PC and type fastboot devices. No period. Should return a serial number on the screen. Your good to go. When you download the fastboot program, put it in a folder on the PC. Also put cwm for your phone in a .img format not a .zip. That should give you a name like cwm-2.5.5.0.img. When you open the terminal, navigate to the folder with both files. After typing fastboot devices and seeing the number type fastboot flash recovery cwm-and-whatever.img
That should give you cwm.
Also you got root have you tried downloading rommanager apk from the net putting it on the sd then installing. Once it installs try to flash recovery from the app

You have to relax first lol. When you're panicky nothing gets done so calm down. Do what the guy above says. Install cwm with fast boot. First install the android sdk then get the drivers. Get fast boot file down as well. Remember that the command fastboot flash whatever varies from operating systems.
With cwm installed, do a test. Backup your efs folder , which is essentially extremely important. You would better do a nandroud backup. Then, try various radios. See if that's your issue. If not change to trying out new roms . Worse case scenario go back to your 2.3.6 rom by flashing with cwm or install cyanogen mod 7.
Best of luck

Follow dreamsforgotten's instructions should get you out of the problem.
And yeah, relax.

You flashed the wrong ROM. the i9020a never got 4.0.3, it went straight from 2.3.6 to 4.0.4. you flashed a ROM for the i9020/i9023. This means that you have a US modem, a problem with those in the gingerbread days is that if you toggled 3G off, you lost it.
Now, I'm not 100% sure this will fix your issue, it *will* bring you back to proper stock image for your phone. Also, keep in mind, that you are responsible for anything you do to your phone, I in no way take any responsibility.
Instructions are for windows
Start by downloading the factory image:
Factory image for your phone
(ref) https://developers.google.com/android/nexus/images
Uncompress this file, you will need the following files:
Image-sojua-imm76d.zip
bootloader-crespo-i9020xxkl1.img
radio-crespo-i9020uckj1.img
Put these all in a folder, you'll need them shortly
Now you need to connect your phone to the computer. follow this guide, part 1 ONLY:
http://forum.xda-developers.com/showthread.php?t=1007782
You should still be in the bootloader when you do the following steps, (turn phone off, press and hold the volume down, power up the phone)
Grab a copy of fastboot.exe and put it in the folder with the IMG files (PM me if you can't find one)
Now, test to make sure your phone is seen by fastboot:
Open a cmd prompt and go to the folder where the img files and fastboot are stored.
Type: fastboot devices
you should get a response like this:
C:\temp\nexus image files>fastboot devices
xxxxxxxxxxxxxxxx fastboot
(x's will be alphanumeric)
This means that fastboot can now see your device. if you get nothing, something went wrong above.. troubleshoot that.
If everything is good, start flashing:
fastboot flash bootloader bootloader-crespo-i9020xxkl1.img
fastboot reboot-bootloader
fastboot flash radio radio-crespo-i9020uckj1.img
fastboot reboot-bootloader
fastboot -w update image-sojua-imm76d.zip
Reboot your phone and be *Very* patient with the first boot.
You should now be good.

Thanks all so very much for all the help! It was extremely helpful and really helped to get my head around things.
What I ended up doing was (for those who might be stuck in the same situation as me):
1) Wipe everything. EVERYTHING. Used fastboot into CWM to help me do that.
2) Put in Kustom Kream found here:
http://forum.xda-developers.com/showthread.php?t=1399956
3) CM9 from here:
http://download.cyanogenmod.com/?type=nightly&device=crespo
* Not super stable to be honest; I've had at least three times where my entire phone randomly shut down and went into the CM9 boot screen and was stuck there until I did a battery pull. Reinstalled each time through CWM. Hope this gets fixed soon!
I found that Kustom Kream put CWM AND rooted my phone AND had everything working in terms of radio bands, sending SMS, etc. I originally had major issues with radios but now I have KB3 although the signal is kind of weak. Maybe because I live in a relatively far out suburban area?
But this solved my problems. Good luck to anyone out there stuck where I am, I feel your pain!

I would recommend that you at least flash a radio that is designed to work with your model - ucjk. That way you won't have any issues if you toggle to 2G.

[Q] In a Bit of a Predicament with Nexus S 4G; is it possible to fix?

So like the genius that I am, I decided to mess with my Nexus S 4G. Right now, my PC will not detect my phone at all (won't show up at ALL, in my Device Manager or any toolkit that I've tried). Please note I had little experience and will probably look like a complete idiot, but bare with me.
So the steps I took were as followed (my phone came already unlocked)
1.) I first installed PDANet to get my computer to recognize my phone and install the right drivers
2.) After that, I flashed the latest, stable clockwork recovery mod
3.) Then, I downloaded the Hellybean ROM and installed it via clockwork recovery mod, with no problems
4.) I downloaded the Google Apps archive and dropped it onto my sdcard
5.) I then installed the google apps zip and then it all went down hill from then
Every time I turned on my phone, the nice Cyanogen mod logo popped up, and then once it was done booting up, it popped up with two error messages:
Code:
Unfortunately, the process com.google.process.gapps has stopped.
Unfortunately, SetUp wizard has stopped.
Both of these error messages will not stop popping up and my phone is currently useless at this stage.
So, I went back into fastboot mode, and tried to fix it with these steps:
1.) I downloaded the "Factory Image "sojua" for Nexus S (850MHz version, i9020a)" images, and followed the instructions on this thread
2.) Once I flashed the bootloader image, my PC no longer detected my phone. It won't show up on my device manages (not even as an unrecognized Android 1.0 phone)
I installed the bootloader image because it was apart of the tutorial on how to do a complete factory reset, I now know that was stupid and not necessary.
So, you can obviously see I didn't know what I was doing, and what I did was quite stupid and careless. So unless you have any suggestions or want to help me, please do not patronize me, I am already mad enough at myself.
With that said, I am unable to even flash anything to my phone anymore, and I don't know what I can do. I tried using Wug's Nexus Toolkit to try and install the drivers, but it won't detect anything. On top of that, I am not sure if I have even flashed the correct bootloader image. Any help or suggestions would be very much appreciated.

Good luck. Flashed a sojua stock ROM on a sojus phone, bootloader and all. I don't know if you'll ever be able to fix this. :|

If you can put it into download mode you might be able to use Odin with a factory image to bring it back to life.

Make sure your cable is connected when you try to put your phone in download mode. Turn off the phone, then hold both volume + and -, and press power. Continue holding volume buttons until you see download mode.

[Q] Anyone else having issues with custom roms? My rundown of steps.

People that can't get the roms beyond stock to work, are your phones activated?
Is it possible to use the Pac Man Rom or CM10 on an unactivated phone?
I'm having similar issues to others trying to flash Pac Man and CM10.2. The first boot was fine and I can access everything on the phone fine, including settings. I rebooted and the activation screen (which I skipped as this phone doesn't have service) always pops up but I would like to use it without putting it on a cell network. I can skip the screen fine (until I decide to disable it) but then have issues like the keyboard (physical and touch), systemUI or NAV Bar crashing with a constant message pop up telling me it has crashed. I have returned to stock using RSD and reflashed Pac Man and CM10.2 MANY (15+?) times, doing a clean install 99% of the time but also trying a couple dirty installs to cover my bases. I should also note that I flashed the phone to Cricket but have no plans to activate it anytime soon.
Another thing to note is that I had issues getting the custom roms to boot at all as the initial setup would take hours. One time I though it was a boot loop but I left it on all night and it had booted in the morning. I believe it has something to do with the file check at boot (with my 32GB low speed class SD card) but that seems to be resolved and I can get the custom roms to boot fine (on the first boot) even with my 32GB (witch is fine and has no errors nor is generic, before you ask.) I also have tried 2 4GB cards and a 2GB card, all different brands, with no change in behavior.
I have done everything below multiple times and in different orders.(If needed I can give a direct breakdown step by step but if you could do it with the files below, I have probably tried it)
Wipe the phone (including all storage internal and external SDs included)
Using RDS v6.15
RDS asanti_c_sprint-user-4.1.2-9.8.2Q-122_XT897_FFW-5-6-release-keys-cid9.xml.zip (Works 100% of the time and never has issues. I keep reverting back to this if I actually need to use the phone)
RDS ClockworkMod, TWRP, and Open Recovery without TWRP (Tried different versions when available)
Then used each recovery to install Pac Man or CM10.2 (tried 10.1 once but had the same issues and I didn't see the need to troubleshoot a rom people seemed to not want to develop for. So 10.1 was only tried once but has the same issues)
Installed GApps at this point but I also tried alternate versions of GApps and not installing it at all. All have the same effect and don't seem to be contributing to the problems at all.
A few installed I tried wiping the phone again or installing each zip multiple times. I also verified the zips were good when on the device to make sure there was no corruption at transfer.
I also tried multiple (confirmed working) SD cards and installing from the internal storage.
I have tried installing arrrghhh's Kernel too.
The issue ether seems to be boot loop (if it's doing a file check) or more often it works until I get one of the said crashes after a reboot.(blame Tyler message is getting SO old...) The time I see the errors seems to be accelerated if I mess with the settings a lot but I don't believe it is directly related to the settings.
My next recourse is to try and flash it back to Sprint (maybe check my Cricket settings) and see if that helps, without it being activated.
On a separate note.
If people need help I can help get you back to stock easily. The instructions/guides on here are all but useless if you don't know what you are doing already. I have seen down to "USE RDS" or "DELETE LINE MD5" like people would just know what that means. I understand RDS Lite is a standard tool for flashing phones but it's nigh impossible to find real explanations on what stuff does in context. I understand the basics though, so if anyone has any questions I can walk you through it.
To start with if you are stuck in a loop at the start of a new rom and it loops between the 'Welcome' Screen (Select your Language) and Activation screen just skip the initial setup by tapping the corners on your screen in a clockwise manor when on the 'Welcome' screen to skip the setup there is a video to explain it here
pocketnow(can't post links )com/how-to/android-quick-tip-how-to-bypass-touch-the-android-to-begin-video
Without doing this or activating the phone it seems to loop between those 2 screens forever (might indicate part of the problem with customs roms....)
I hope this is enough info to go off of I can give you a play by play with the actual files if you need. Maybe a video if needed and I'm feeling extra fancy.
Thanks for your time.

Hey buddy,
If you're trying to make a guide, make sure you call it what it is properly - RSD Lite.
Also, maybe clean up your post a bit so it's a proper guide (as you point out, it's needed) and make a separate thread for your question.
To answer your question, the unactivated phone shouldn't be an issue in of itself - you'll just get the nag screen like you were talking about.
I know there is an issue some are having with rebooting the 4.3 ROM's. Have you tried any 4.2.2 versions of anything? Carbon, CM10.1?
I wonder if your "flash" to Cricket is causing issue, I'm not sure. Let me know about 4.2.
Edit - I missed this part on my first read of your PM. Taking hours to boot is NOT normal. Perhaps remove the SD card entirely, flash using the internal SD... I've never heard of that. Anything over say 20 minutes is probably cause for concern.

Thanks for taking time to answer me.
In no way was I trying to make a guide yet but I guess I could. I just hate posting stuff without useful content so I figured throwing that in was better than nothing. I'll clean it up and set up some links later today. It's frustrating to try and make a full guide before I can post links that would be needed for it. You are totally right though! (complain about crappy guides and kind of make one... )
Part of my point there was that I can't post out of Q and A and this wasn't really a question so I made a question out of it and that's how my post ended up.
I have flashed many phones before but like I said I'll try and put it back on Sprint later today (probably will be a few hours) as I backed up the settings the phone came with. I know it was a wall of text and not the easiest to read so you probably missed it but I also said in my first post that I tried the internal SD card many times and the taking hours to boot isn't the standard and doesn't seem to happen at 99% of the time. It seems to be related to the recovery software I use as it happened a lot more when I was testing TWRP and none when I use clockwork.
What Recovery do you recommend? I swear they aren't made equal...
I tested CM10.1 once and it had the exact same issues as CM10.2 and Pac Man so I didn't test it further but if you want me to test it I can. I just didn't want the Rom.
I don't want Carbon either but I'll test that and AOKP next. It's just annoying that the stock rom works perfect but I can't get these to function at all. I almost wish I didn't get Pac Man to work at all. I'm very particular about my settings and NEED these features after I tried them Pac Man is AMAZING.
Thank you for the help and I hope I can get this worked out.
PS I saw that you were frustrated about working on a rom you don't have a device for. I hope you don't let a little thing like that stop you as, for the little time I have used it, it's all I want. Thanks again.

Well, OpenRecovery has probably the most work done for this device specifically. I liked TWRP, but it seems lately it has been unstable - you're not the first who has reported issues lately. I don't think CWM has been updated, unfortunately - but perhaps that's a good thing, it's stable that's for sure.

Blasz- I was just about to start a thread when I found yours, and it very accurately describes the issues I've been having. Here's my progress so far.
I got my Photon Q with Sprint and used it for a few months before Sprint started finding creative ways to take my "$79.99" bill and make it more like $140 a month. Naturally, I refused to pay. So I had a Photon Q with no cell service. This is fine, as I only need it to work on WiFi, not 2G/3G and there is no 4G in the area. Anyway.
At the time, I had Ice Cream Sandwich on it, using the (latest?) ICS firmware from Motorola. This worked very well, but I later tried to use a newer firmware, and all the custom ROMs had shown up while I hadn't been looking. All of these seemed to be based on JellyBean. First off, I tried CyanogenMod 10.2. Worked amazing well! I had literally no problems at all. However, while I was experimenting with different software for the phone, and wanted to see if "Arrrgghh"(sp?)'s kernels would give me some decent overclocking capability. Turns out, the kernel I picked wasn't compatible with the JB firmwares (I probably picked an older one by mistake.) Needless to say, it now wouldn't boot. It'd go to the "Unlocked bootloader" screen and stay there all night (literally, I tried that.)
So, I went back into CWM, which is the recovery I have installed. I erased /data, /cache and /system, and also the dalvik cache and battery stats for good measure. I also formatted /pds and /modem, I believe, which was probably dumb of me since I'm not sure what those do. Then I tried re-installing CM 10.2 from CWM. The installation went fine, and it works gorgeously. However, there's two weird issues:
1) WiFi and Bluetooth don't even BEGIN to work! Neither does Cell, as far as I can tell, because where CM used to be unable to make calls or access the internet (of course, I've not been paying my bill), it now shows an empty signal bar or "No Signal" (the little red X) in the notification bar ... When I try to turn on WiFi using the slider in Settings, it moves to "ON" (stays gray) and pauses for a few secs, then goes back to OFF. Same thing for BT. If I open the WiFi menu where you select an AP, it tells me to turn on WiFi. I do, using the slider up top, and the same thing happens. WiFi and BT simply won't turn on. Tried fiddling with every setting I can find.
Before this misadventure with the kernel/reinstall, WiFi worked great. I connected to a local AP and was surfing the net and downloading apps.
2) The system takes a VERY long time to boot up. It sits at the "Unlocked Bootloader" screen for up to a whole minute. Then it goes to the Cyanogen screen for about 30 seconds. Then it gets to the homescreen. It's fine so long as you let it boot up, but this doesn't seem normal.
Next I tried other ROMs thinking that might help. I installed AOKP, PacMan, CM1.0, Carbon, SlimBean, and I think a few others without results-- they all work but WiFi and BlueTooth are dead. PacMan is the only exception-- it boots up and then endlessly gives me "Blame Tyler" errors until I force the machine to shut off.
I also tried an older ROM, since these are all JellyBean ROMs and I wanted to get back to ICS (I'm not that fond of JB's interface) anyway. I was unable to find any ZIPs I could install through CWM of the stock firmware. I found some IMGs that it looks like I could install via Fastboot, but I don't currently have a PC with admin priveleges (it's not mine) so I can't install the drivers to use Fastboot or any part of the SDK. (I can, however, put files on my SD card, that doesn't require privleges.) The closest ROM I found to stock was "TwistedAsanti" beta-1 or whatever it's called. That installs fine, but again, it takes about 2 straight minutes to boot and it's useless after that:
It gets stuck at "Starting Services..." and will sit there forever, even left there all night. Behind this, a dialog pops up saying no cell networks were found and asking if I want to switch to GSM. (i've been trying GSM and CDMA ROMs all this time, I don't need cell access so I doubt it matters which I use. I'm in the USA.) You can pull down the notification bar and get into the Settings, and even launch a couple programs, but I can't find ANY way to get to a homescreen. Task manager shows Circles is running, which is a widget on the homescreen, so where the heck is that screen? .. I try, again, to turn on WiFi or BT without success. The friggin thing just won't turn on.
Did I eff it up by erasing the "PDS" or "modem" partition? Am I missing something obvious or is my phone just possessed?
In a few days I should have access to a computer where I can hopefully use Fastboot and see about installing a stock firmware (wish me luck). Until then, does anyone have a ZIP file I can flash from CWM to get back to an ICS firmware? I managed to find a copy of the stock firmware, in the form of a dump done from TWRP (in .win files). But as far as I know the only way to install TWRP is using Fastboot, and I've explained why I can't do that. I don't know a way to install TWRP from CWM. Maybe I can do it from CM10.2, if I can put APKs or something on my SD card. I can't get it on the network, so I have to copy all the files manually. Needless to say, it's a pain.
After my frenzy of ROM installing, I got frustrated and decided to see if TwistedAsanti would do SOMETHING if I let it sit at "Starting Services" overnight. To my mistake, I left it under my pillow and the system was quite toasty, and the battery had run dead. Plugging it back into the charger, it made a few worrying clicking noises from the speaker, then the green LED came on. This LED seems to mean "I'm charging, but the battery is too dead to turn on for a while." After it sits there a while, the green LED turns off and it just goes black. Or it goes to BOOTLOADER UNLOCKED and bootloops, or goes to black untilyou fiddle with the power button some more. I can once in a blue moon get to CWM. Sometimes it gets to the homescreen. It will charge up to about 4-7% and no further (battery got damaged by the heat?) It doesn't reliably work when plugged in, it likes to shut off at random anyway.
So now I'm stuck with a phone I can't seem to charge, or turn on reliably, and if I *do* get it to boot up, there's no way to connect it to a network.
Needless to say I'm pretty darn frustrated..
Thanks for any advice.

Currently, I have no PC to use that has Admin priveleges, so I can't install the USB drivers or RSDLite. I also can't use fastboot to install TWRP to use the TWRP .win backups I found.
I did get a roommate to let me use his laptop for 10 minutes to try RSD Lite, but I had this result: Loaded the ".xml.zip" file for the 4.0.4 and 4.1.2 firmwares (after removing the 'getvar' line that causes problems) and it says the phone reported "FAIL". No further details. MiniRSD gives no info from the phone other than the model (it all stays blank), is that supposed to happen? I have the phone in "AP Fastboot" mode so I don't see the problem.
The guy who let me use his PC momentarily is computer-illiterate and thinks anything will break it, so he only let me use it momentarily, and won't let me touch it because I accidentally left an icon on his desktop. I'll have to ask someone else, I think I may know somone..
If I do, how do I get around this error in RSD Lite? Will keep doing research on my own .. thanks!

I did get a roommate to let me use his laptop for 10 minutes to try RSD Lite, but I had this result: Loaded the ".xml.zip" file for the 4.0.4 and 4.1.2 firmwares (after removing the 'getvar' line that causes problems) and it says the phone reported "FAIL". No further details. MiniRSD gives no info from the phone other than the model (it all stays blank), is that supposed to happen? I have the phone in "AP Fastboot" mode so I don't see the problem.
The guy who let me use his PC momentarily is computer-illiterate and thinks anything will break it, so he only let me use it momentarily, and won't let me touch it because I accidentally left an icon on his desktop. I'll have to ask someone else, I think I may know somone..
If I do, how do I get around this error in RSD Lite? Will keep doing research on my own .. thanks!

Well remember - if you are on JB and you are downgrading to ICS, there are additional lines to remove.
Other than that, not sure why it would fail. Make sure 'fastboot devices' works in the command line before doing RSD perhaps.

I'm trying to wipe the device clean and install ICS. Are there any other lines I need to remove? ..
As for Fastboot.. I did 'Fastboot Devices' and got no devices listed. How come it shows up in MiniRSD? .. I have the drivers installed, Windows says it installed an ADB device successfully. What are some reasons that might not work? Is there any sort of guide for this? Thank you

Oh, as far as the weird booting problem, it seems the battery is fine and the charger died coincidentally at the same time as the overheating did. So my only problem is software now.. thanks.

I have no clue what MiniRSD is - you mean RSD Lite?
If it doesn't show up in fastboot devices, sort that out before trying to use RSD.
As I stated previously, if you were on JB and going down to ICS you have additional lines which are needed to remove.

Yes, RSD Lite. I don't know where I got MiniRSD from.
I got it to show up in fastboot devices, but adb devices doesn't show it. Weird. Is that OK?
I was able to flash TWRP to the phone with Fastboot. RSD Lite was unable to find the phone. However, I opened the XML file and was able to figure out the flash commands to enter from a command prompt, so I did that:
I got these results... all of the files flashed successfully to stock, except for two. I forget the first, haven't got it in front of me, but here's the big one: SYSTEM! (Important, no?) Here's the error from fastboot:
>> fastboot flash system system.img.ext4
fastboot said:
target reports max download size 31457280 bytes
Invalid sparse file format at header magi

(then, Fastboot crashes.)
Does anyone know how to fix that? Also, the system image is way bigger than 31.4 MB. What is it talking about?
Thanks!

I would NOT recommend entering those fastboot commands in the XML file manually unless you KNOW what you are doing.
Sort out why RSD isn't working. adb and fastboot are two different things. If fastboot devices shows the device, RSD Lite should work fine. Try again.

One S dead after trying to flash CM11

Hi there,
i have a huge problem. As there was no warrenty left for my One S I thought about to change the firmware to CM11.
I have to admit that i don't have any experience in doing such things, but i thought, it couldnt go wrong if i follow a tutorial.
So at first i unlocked the bootloader via HTC website and istalled TWRP 2.7.1 (latest version). Everything went well, I placed the ROM into the phones root directory, started the recovery and then whiped it before choosing install and selected the file. After about 30 seconds the phone reported the step was successful and i pressed reboot. Then there was the HTC starting screen and then a black screen.
After that i had no reaction but the blinking buttons when i press the power button for a longer time. But it changes nothing. No normal boot. No access to fastboot. Only if i connect it to my PC there is an aditional device to see, but whitout any access.
I know I did wrong but i have no idea what or how to fix it. I hope you can help me.

Now i found a way to get access to fastboot again, but i dont really know what to do now.
Can you give me an detailed tutorial, for jelly bean or kitkat (dont matter) that is surely working now?
My main problem is that i can't copy my files into the root directory as i cant boot the phone.

Does it show up in computer connected devices?
If it does, download stock kernel and ROM and upload to phone and go into recovery[power +volume up while off] and flash them both kernel first.

The problem is the phone wasnt ever shown as device on the pc (like a flash drive) since version 4.1 so I allways needed some tricks like airdroid. So i suppose i need adb commands to copy files and i dont have so much experience in doing this.

Do you know how to use adb?You don't need adb I just wanted to know to see if it shows up there and not on computer you simply need to install the drivers.Try holding down all 3 buttons to see if it powers down. Do what it says http://www.technewscentral.co.uk/enter-fastbootbootloader-mode-htc-one/id_7930 if works go into fast boot. Does it say locked or unlocked. If unlocked go herehttps://github.com/koush/UniversalAdbDriver and get the windows installer if your on windows.

I now found out how adb and fastboot are working, but the main problem now is, that it says the sdcard cant be mounted. I tried this tutorial http://forum.xda-developers.com/showthread.php?p=25557817#post25850720 but i dont know how to do the first step. Du i need an extra file and where do i get it from and how to use it. As long as i dont get back this access, i couldnt install any OS. I tried also sideload. It was able to copy but cant install because of the missing sdcard access.
I hope you can help me to become my phone running again.

Go here http://m.youtube.com/watch?v=xWmnHwkDrKk but first type adb devices in cmd. If it shows ur HTC type adb shell and and type mount sdcard next to the "#" once it appears although you should be using the fastboot shell not adb commands.adb should only work on a powered on device or you can use fast boot in cmd while phone is in fastboot not recovery(you did say the phone can go into fast boot right?). Just make sure you got the right drivers and both fast boot and adb. You should get Koush's Universal drivers from my previous post since some phones have multiple drivers and MAY cause problems with cmd. Also HTC one S doesn't have expandable storage correct?

Wow. Now I incidentally soft bricked my phone again if you would believe it and nothing works this time.

Have you been able to fix?
Sent from my ZTE_N9511

Okay, i forgot to write but adb and fastboot are working on my Mac. I use the Mac because Win 8.1 has the known driver problems.
I tried a lot now, but i recognized maybe the main problem. My phone is still S-ON in bootloader. For sure thats the problem. Do I need to get rid of it and how do I do. The tutorial i used hasn't mentioned this step, maybe the person was still S-OFF.
The first thing i try now is to flash the original recovery, lock the bootloader and execute the original signed RUU to get back the original software first. Im going on holiday on tuesday and it would be a pitty without the phone. When I get it working i will leave it, and thy it again, when I'm back. Otherwise.......****

Use this tutorialhttp://htc-one.wonderhowto.com/how-to/fix-soft-bricked-htc-one-by-flashing-new-rom-via-adb-0154361/unless its the one you used already. From boot loader you were supposed to have gone to fastboot.boot loader has to be unlocked.From fast boot you flash TWRP.IMG which happens to have a special adb side load feature under advanced options. There you upload another ROM and kernel.here is the full list of supported devices as I don't know what variant or carrier you havehttp://teamw.in/twrp_view_all_devicesAlso, a stock kernel is optional but it always seems to fix my problems.
Sent from my ZTE_N9511

Thank you. But I already did it like this. The issue is, than after using sideload successfully the installation fails because of the known "unable to mount storage" text. And i don't know what to do wrong.
Like I already said, my phone is still S-ON, but can this make a difference?
Now i got it to bring the stock ROM running again, and as I'm on holiday for a few days I'm happy it is working again.
But one thing is left. It seems like there is no 3G/HSDPA connection now, only EDGE. I dont know what went wrong. Did you hear about this problem.
By the way, my phone is the standalone version whithout any provider.

Search the forums about edge only. There is a huge thread on this.

LG V20 H918 T-Mobile Guide from out-of-the box --> 20H, TWRP, Root

hi,
this is a guide for real helpless people, that got a V20 H918 T-Mobile out of the box and have no idea
what to do, to get TWRP and root. and since on this phone its a REAL hard odyssee if youre not a pro,
and you dont want to spend days and weeks to pick up countless small puzzlepieces to finally get all together up and running, i decided to write this guide. im no pro myself, but with countless hours of reading and try and error, misery, headaches and brainpain, i managed to get this thing running all right with working downloadmode,
newest TWRP-version and 20H oreo 8.0
so far, everything seems working good. ill play around with this version and if i encounter some crap, i will edit this guide later. sadly most "newbie-guides" here, are from pros for advanced users with decent knowledge. so when u start from zero, you dont understand half of what is written. thats why i will keep this guide as simple as possible, with some side explanations. its a lot to read and a lot to do, but this way works!
what we have before starting:
a V20 H918 t-mobile 20H oreo 8.0 with bootloader locked. simply a crippled standard phone.
what we will have after this guide:
a V20 H918 t-mobile 20H oreo 8.0 rooted, with unlocked bootloader, working downloadmode,
and newest TWRP-version.
with twrp u can backup your whole system "as it is", means u fukk up your phone, simply go to twrp-recovery, restore your backup and you have your phone up and running 100% as before all went down the drain. simply and easy. just like a new installation of win10, but in 5 minutes. u can flash custom roms, kernels etc., install all kind of stuff, no need to pay for apps anymore, get rid of obnoxious bloatware, just 100% freedom and the full potential with the V20 (which is the last phone of its kind with exchangable battery, which is why i got myself 3pcs of it )
sidenote: get yourself some extra protection foils so u can change from time to time.
also get yourself 1 or 2 10000mah powerbatterys from aliexpress (perfine) with protective rubbercase, of course, they dont have the printed-on mah, but at least a considerable amount, so that your phone will last at least 3-6 days. my V10 lastet 11 days normal usage with zerolemon powerbattery. unfortunately, these retards refuse to send to europe, and as far as i know, theyre not producing for LG phones anymore, so aliexpress/perfine is whats left.
the rubbercase gives the phone a superior protection, adds a serious amount of weight and will stick in your hand like glue. it is by far less likely to drop out of your hand like these glass-phones for imbeciles. and if it drops, the rubbercase grants excellent protection. my V10 dropped countless times, still working perfect.
but lets get to the guide now.
at first, we will unlock the bootloader. without it, you wont be able to do anything.
unfortunately, LG produces great phones (with great audio!) but terrorizes the users with their strict anti-root attitude. it seems it gets harder everytime to root and unlock the bootloader. i remember back in the days old samsung devices, had been rooted in no time. this one here cost me about 2 weeks.
on this phone, u simply cant hook it up to the pc, and unlock the bootloader with adb. it will be recognized by the pc, but as soon as u enter fastboot, nothing will happen, no command works.
the solution is a FWUL (forget windows use linux) usb-bootstick, with that u boot your
pc into a custom linux (i think) only here u have full access to your phone via fastboot and can unlock the bootloader in no time. it will not work on win10 !
- first, get rufus, a win10 tool, with that u can create boot-usb-sticks.
https://rufus.akeo.ie/
- then get the linux FWUL image (only 15GB version is still up)
https://androidfilehost.com/?w=files&flid=214529
- unzip the linux image to your c drive or your desktop.
- start rufus and select your usb-stick (it should be 30gb+ in size)
be carefull not to chose any other drive or stick (it will get erased completely), better double check.
- select the image you just unziped. (i use 7zip for unzipping)
- leave all other options as they are, press start. when dialog-box pops up, chose DD-mode !
- now waste some time, as it takes a long time to create the bootstick (in my case about 30min)
- when the stick is ready, in my case it couldnt be recognized anymore in win10, its just a raw-drive, that cant be
opened. thats allright. dont worry
- now close down all applications running and insert the created bootstick. (at this time u might consider using a
separate laptop, so you can follow this guide here at pc and use the laptop with linux running, thats what i did)
restart your pc, hit F2 or F8 oder DEL or whatever to enter bios.
select the created stick as bootpriority nr1. so that the system will use this stick as
the first bootmedium to boot from.
- u get to a screen with 9 bootoptions to chose from. chose the first one. it should now boot into linux.
when password request pops up, enter: linux
- u reach the "desktop"
connect your LG V20 H918 20H via usb-c to the pc, which has linux running, make sure that
developer options are unlocked, OEM-unlock and USB-debugging is enabled and u chose picture transfer protocol
(PTP) as transfer-protocol (also in developer options). if PTP doesnt work, try media transfer protocol.
watch your V20, at some point it will ask for confirmation of connection , click OK.
in linux, click on the up-arrow in the most downleft corner and chose "terminal emulator", which is
a pendant to windows shell/command-line.
- here you can execute the adb commands.
first, check if your V20 has been recognized by your pc with linux running.
type: adb devices
it should appear a message like:
* daemon started successfully *
LGH9182bfblablabla device
that means, that your V20 has been recognized correctly. now you can reboot it in fastboot mode.
type: adb reboot bootloader
your V20 screen goes black and seconds after, it restarts in bootloader mode ready for unlocking.
you might get a red warning that your warranty is void if bootloader is unlocked. cool.
type: fastboot oem unlock
wait for response, your bootloader is now unlocked.
u can check by typing: fastboot getvar unlocked
it should say: yes.
the bootloader is now unlocked.
now we will replace the standard recovery with twrp on the phone.
this step will be a little confusing and complicate, just follow the steps, and it will work.
since we cant flash twrp with adb, we have to use the linux bootstick again.
but before, we have to downgrade the 20H version to 10P, bcuz the next stepp will not work with 20H !
so you get the following:
DOWNLOAD H91810P KDZ FILE
https://androidfilehost.com/?w=files&flid=282709
after that, download LGUP (the LG tool for downgrading from 20H to 10P)
and uppercut (dont know what uppercut is for, i just used it instead of running LGUP directly and it worked. its supposed to recognize the phone/driver automatically)
http://downloads.codefi.re/autoprime...sh_Tools/LGUP/
and download the recent LG-usb drivers.
http://tool.cdn.gdms.lge.com/dn/down...=UW00120120425
install LGUP, uppercut and usb-drivers.
connect ur phone to pc in download mode.
turn of phone, press and hold vol.UP button and connect usb cable, small message appears, phone is now in download-mode and waiting.
now run uppercut and hope, that ur phone will be recognized. if not, think about, what kind of restrictions u did to ur system, like OnO-shutup or xpantispy (both great programs to keep win10 from calling home to scum gates) or whatever. in my case, it ONLY worked, after i reset the OnOshutup settings to recommended. so the phone get recognized correctly in LGUP (if not, try laptop or different pc), select upgrade and select the downloaded 10p KDZ file. press start or go, and wait until the procedure is finished.
now your phone is downgraded to 10p.
now we go back to linux, we connect the phone in downloadmode with the pc/laptop where linux is running,
(turn phone off, hold volUP, connect usb-c-cable with linux-pc/laptop, phone will start in download-mode.)
make sure, your laptop/pc has internetaccess.
on the linux-desktop, click on the LG folder, inside, click on LGLAF runningnaked.
a terminal-window opens.
type: git pull
type: git checkout h918-miscwrte
type: ./step1.sh
now we have flashed twrp onto downloadmode. why? i dont know, thats the way it worked for me.
we dont want twrp onto downloadmode, since twrp is a recovery. so the next step is, to flash the newest twrp version for H918 to recovery. at first, we will gather all neccessary downloads, after that, we will flash them one by one. that way, you dont have to get your micro-sd card out of your phone again and again. we put all together on the card, put the card in your phone and we are almost done. for now, have your micro-sdcard connected
with your pc and download the following:
twrp-3.4.0-1-h918.img
from
https://dl.twrp.me/h918/twrp-3.4.0-1-h918.img.html
and put this .img file on micro-sd card.
then download (and put on sd-card):
MAGISK ZIP DOWNLOAD (for root)
https://github.com/topjohnwu/Magisk/...gisk-v16.0.zip
then download original 20H firmware(and put on sd-card)
H918 20H
https://androidfilehost.com/?fid=11410963190603864639
you remember, we have now twrp on downloadmode
for restoring download-mode, download (keep on desktop or c):
H91820h_00_1115.kdz
https://lg-firmwares.com/downloads-file/17076/H91820h_00_1115
then download the firmware extractor:
https://forum.xda-developers.com/attachment.php?attachmentid=3975633&d=1482337024
ok, lets see what we have now:
we have the phone bootloader unlocked and twrp on downloadmode. we can access twrp when we start the phone in downloadmode (hold volUP, and connect usbcable, phone will start now in twrp.)
we dont want twrp on downloadmode, we want twrp as recovery. and we want to restore the original downloadmode. for that we do the following:
unfortunately, the neccessary file for flashing orignal downloadmode is not online anymore, so we have to extract it from the 20H firmware with the firmware extractor (thanks to logical gamer for his guide)
https://forum.xda-developers.com/v20/how-to/guide-h918-restore-laf-partition-t3804728
Extract WindowsLGFirmwareExtract vx.x.x.x. to your desktop, and open it up (preferably in it's own folder).
u might have to install framework 3.5 for it to run.
Select Open across from KDZ/TOT file, and browse to your KDZ (H91820h_00_1115.kdz)
you download previously and double click.
After it loads the kdz check H91820h00.dz, and click Extract KDZ.
Close and re open the program this time Click open across from DZ File in the folder where you placed WindowsLGFirmwareExtract you should see a file called H91820h00.dz Double click to open it.
Check laf_6.bin then click Extract DZ.
put this laf_6.bin on your micro-sdcard. thats your original downloadmode we will flash now.
ok, now we have our micro-sdcard with twrp, magisk, laf_6.bin and H91820h.zip.
put this mirco-sdcard in your phone. start the phone in downloadmode.
it will start in an older twrp-version. in twrp, go to install and select install img
select the twrp 3.4.0.1. img and on the following screen select "recovery"
swipe
this will flash the 3.4.0.1 version of twrp onto recovery.
then go to reboot into recovery. it will now boot into the newly flashed recovery.
then go to wipe, advanced, and select everything EXCEPT micro-sdcard!
this will totally wipe your phone (except twrp), so u can flash the 20H firmware onto a clean phone.
then, go to install, select H91820h.zip. this will flash your original oreo 8.0 firmware.
after that, go to reboot into recovery.
go to install, select magisk. install.
this will root your phone.
after that, reboot into recovery, go to install, select install img, select the laf_6.bin, and select "download"
now the original downloadmode has been restored.
now you can reboot into system, your phone will start as on day1, with new twrp on recovery and root.
i did a complete backup in twrp, so i can get back to a day0 clean install whenever needed. i will do a second backup with twrp with all the stuff installed and working ok and place this on my sd-card. so when things go bad, i always can go back to this state in no time.
congrats, your done. and me too . gonna get a cold one now.
hope this guide will help someone. in case, just drop a like/thanks/or just a short note.
its a long guide, and im no pro, if i made some mistake pls. tell here and i will correct.
thx to all the pro-guys for helping the helpless.

Hi
Im on v20 H918 firmware 10p with bootloader unlocked.
I tried with dirty cow but not works with lafsploit i have a Problem with rufus for create a bootable Linux.
Pendrive is 32 GB i followed your setting but my PC boot only in windows 7.
I succesfully unlocked a h990ds with dirty santa but for this model is not supported.
Can you help me

hi
i tried with dirtycow also, didnt work.
thats why i eventually came to the method i described.
teling by your short description, your next step would be to create a bootable linux-usb-stick, and to find a pc where it will boot correctly. the stick didnt boot on my main pc ( i dont know why, it just canceled with an error),
thats why i had to use the laptop where it worked.

Thanks for the guide man! Very funny and fun to read. I can't wait to turn mine into a 4-day brick like yours. #lastphonewithbatteryrevolution
Sadly I got the dreaded encrypted error at the end though when booting. Everything else worked fine.
After the encrypted error though I formatted and flashed LineageOS 17.1 and then magisk and still keep getting error 1. Even tried Lineage recovery and still same. I think maybe a problem with Magisk 16 itself.
Anyway it works fine just no root.
Edit: Had to flash Magisk 21 and it worked

Thanks for this tutorial. I was able to get my V20 rooted with minimal trouble. The only major trouble was finding a computer that will fully boot into Linux and the only minor issue was locating the UPPERCUT but I was able to find it. Link below.
It's probably worth mentioning that I had to rename laf_6.bin to laf_6.img in order to flash it in TWRP. Also, at the time of writing, the latest version of Magisk is 22.0 but I used Magisk v21.4 instead because it had a zip file (Magisk-v21.4.zip) available for download so that I can flash it via TWRP. Link below.

cool, glad this guide helped at least a little bit. my v20 still works great, no issues so far. as a side phone for unwanted persons, i still use my v10 with powerakku and rubbercase "brickstyle" every time i hold a regular phone from other people, it feels weird since these phones weigh like nothing, and i have to focus not to slip it out of my hand. i love my bricks
and by now, about 4 month later, reading this whole guide, to me its still strange and hard to follow. there is no way to get through this without reading everything possible about it and become familiar with all the technical terms.

I have a h918 with an unlocked bootloader and it's downgraded to 10p. The shell script fails everytime to a hash check. I've run it 4 separate times with the hashes being the same every time. So it looks like the file has been updated but the hash hasn't.
I'm coming late to the game and it seems most of the guides are out of date. I'd appreciate any help I can get.
Update: It works fine. This is by far the easiest guide to follow that I've found. Many thanks! I did have to follow xstahsie's tip.

I followed the guide after I rooted and installed Lineage OS 18.1. I had to remove LineageOS because it was bad with response, couldn't see hidden wifi, and just ran hot. So I followed your guide and I am in a logo bootloop and get the reminder to lock the bootloader everytime it starts. Any suggestions for getting past the bootloop?

I fixed problem by installing LAF you referenced and then LGUP to 10p kdz. However I noticed two things.
1) Whenever I boot up I have the nag message to my bootloader. Any way to address this?
2) If I try to follow steps above to install 20h, I get a decrypt message in TWRP after I flash 20h and before Magisk. Anyone see this? I didn't encrypt my storage before hand.

You're stuck with it, it's just the way it will be from now on.

I don't remember seeing that. I probably didn't care if it did show up since it was a new install from scratch anyway.

Does encrypting the phone work after following this guide?

hey there, cant help u with the encryption thing cuz thats far beyond my knowledge. some weeks ago my phone dropped, and a tiny crack on the edge appeared. what i didnt know was that this crack is the beginning of the end of the V20. heres the story short: small crack over time leads to a bigger crack, bigger crack multiplies and u have some more cracks covering the whole screen. also the screen can pop off and hanging loose a little. in my case 4-6 weeks and i have to get out phone 2/3 which i am setting up using this guide now. fortunately i left myself a huge pyle of information on how to do this when starting at 0. over time u forget EVERYTHING u have done, so having these infos is hammering.
lucky me did i save my internal memory of phone 1/3 bcuz 30min later the screen was totally fuqqed up, no access no chance of backupping internal memory.
so heres my recommendation:
DONT drop your phone. even in my case with rubber battery case from aliexpress
(perfine "10000"mah) a 50cm drop cracked the edge of the screen. if that happens, backup your internal memory !!! (just do this on a regular base)
when ur screen gets damaged and u cant enter information or cant see anything anymore on the screen ur internal data is lost. so always have ur internal memory backuped!
and great job LG for producing such a huge pyle of ****. one small drop, screen cracked, bravo, last time i ever bought anything from lg. my V10 dropped like a 1000times, nothing, still up and running. v20, drop, 6weeks later, dead. thanks LG the customers all over the world couldnt wait to use these bull**** crackable glass-screens. great job, -1 customer.

I've tried this on two different computers with two different cables in every USB port on the machines but can't get by the Windows portion. I am using UPPERCUT as the windows box/LGUP reports no device found without it...
Of course UPPERCUT drives windows security mad as it's reported as doing bad things but as I'm using an extra win laptop that will be wiped I disable all of that....
I have three different sourced KDZ files as the one linked wasn't initially reporting any mirrors. Eventually a mirror did pop up for it but by then I had downloaded two others -- all were the same size and one of the three reported from LGUP was bad. Every attempt with the other two failed. Invalid Command response came up a few times... sometimes it just failed at around 80+ percent from the PC side which was 99% on the phone's downloader mode progress bar.
It's very frustrating.... I would like to blame windows but there seem to me plenty here with success... any other ideas?

Also... since it got so far, rebooting at this point just goes to the download mode so I might be hosed... I can force it to the fastboot mode and it is still unlocked so I've been trying to install TWRP onto recovery using the linux/android machine but when I type
fastboot flash recovery twrp.img from the directory where twrp was downloaded I get this:
sending recovery --- okay
writing recovery --- failed remote: unknown command
So... any thoughts?

aloha, at which step are u stuck exactly? did u make your phone being recognized by the win10 pc?
one thing to regard is, that a usb-CHARGING cable possibly wont work, u need a designated media/data-cable.
i had this situation before, where using many different usb cables drove me insane bcuz i simply couldnt establish a proper data connection with phone/pc, it just didnt work. it took me many hours until i realized, that all of the cables i tried were charging cables!
for me the most difficult step was having the phone being recognized by the win-pc, the rest went relatively easy.

The phone is recognized by the PC, no problem. I do have to use UPPERCUT to get LGUP to recognize it though. The step I'm stuck at is applying the downgrade. It gets to various percentages of done-ness and fails. It got far enough that now my only options on the phone are Download mode or fastboot mode. Problem is, I can't seem to get anything to push to recovery so I assume that it's still not properly downgraded.
I've tried a few different cables and keep in mind the cable I used in the linux adb bootloader step worked fine. I don't entirely know what difference there is between a charging and data cable but I do know the main differences in the steps are a> Windows and b> size of transfer.

weird. since im no pro myself, my ideas are limited on this one. there might be some kind of loose contact at the charging port,
that when the phone is moved just a little it looses connection for a second and reconnects again, had that in the past, so try not to touch the phone at all. did u use the 10p kdz file mentioned before? did u make sure it has been downloaded correctly?
if an error occured and there are some % missing... its like faulty ram, hard to detect.
assuming, u did or did not downgrade to 10p, did u try to continue with the linux-step? ---->
---------------------------
on the linux-desktop, click on the LG folder, inside, click on LGLAF runningnaked.
a terminal-window opens.
type: git pull
type: git checkout h918-miscwrte
type: ./step1.sh
now we have flashed twrp onto downloadmode
-----------------------------
maybe uppercut/lgup displayed an error message for no reason, and the downgrade itself went through without a problem in the background.
pcs sometimes do weird things.
if nothing works, try setting up win10 and try on a virgin system. in my case, OnOshutup prevented win10 from recognizing the phone,
or try using a 3rd pc from a friend.
i was able to setup my phone 2/3 using this guide in 30min, no problems at all. (i hope i wrote down, how i solved that simlock issue.....)
no matter what causes the problemin ur case , id be interested to hear what it was.

Thanks! Rooted and Unlocked thanks to this guide!

I tried following other guides using UPPERCUT and it fails to downgrade due to Anti Roll Back. How does this relate to this guide since the last thing I want is for (by design) for it to brick the phone. I have yet to find anything specific saying an unlocked bootloader will bypass the anti rollback check.

Hi As a noob does this keep VoLTE? I have followed this guide and backgrade to 10p was perfect! VoLTE working on a phone that was "new" from china. VoLTE did not work on the 20p rom it had. Also does anyone prefer Phoenix591's h918-20g-prerooted rom to the stock one? I have read a lot but am somewhat confused by varying instruction threads. I want to use this as a daily driver. Thanks
